TECHNICAL FIELD
[0001] The present disclosure relates to a feeder device configured for mounting on a shelf
for feeding successive products to a front of the shelf. The feeder device comprises
a spring arranged to act on a sled for pushing the products towards the front of the
shelf. The feeder device may be used e.g. in shops such as grocery stores or the like
for providing and displaying products on shelves therein.
BACKGROUND
[0002] Feeder devices for merchandising in general are used for example in grocery stores
where goods are exposed on the shelves. Indexing devices are used to push forward
placed goods or stored items, in a row one behind the other, to the shelf's front
edge, to facilitate the picking of the goods, improve visibility of the goods and
make the shelf aesthetic appearance more appealing.
[0003] The feeder device may include a base or web which is placed on the shelf so that
it extends from the shelf front edge in a rearward direction. A feed sled is slidably
disposed on the base along its length. The automatic feeder devices are sled biased,
for example by a helical spring which is arranged on the backside of the sled and
which at one end is attached to the front end of the base.
[0004] To improve the system of the shelves and to separate neighbouring goods from one
another feeder devices are often used together with shelf dividers or partitions.
The dividers comprise a dividing wall that extends from the shelf front edge in an
essentially rearward direction. Dividers may also comprise a front stop plate or front
extending perpendicularly to dividing wall on one or both sides of said wall, to prevent
goods from falling off the shelf. The dividers are attached to the shelf next to each
other to form compartments in which the feeder devices are placed. The distances between
dividers are chosen in accordance with the relevant goods width, so that the goods
are brought into line with each other in their respective compartments. This minimizes
the space required to store the goods on the shelf, while the shelf aesthetic appearance
becomes more appealing. To fit the different products and product packaging, dividers
can be designed in a variety of ways. For example, the dividing wall height may vary
widely. Furthermore, the fronts of the dividers can be designed in a variety of ways,
for example as regards the width, height and contour, to suit different goods and
to provide desired visual impact for every occasion.
[0005] Feeder devices and dividers should be easy to assemble and disassemble from the shelf.
The feeder devices and the partitions should also preferably be possible to fix at
arbitrary positions laterally along the shelf, to thereby provide the goods compartment
with the desired width.
[0006] DE 1 297 833 discloses a feeder comprising a product supporting wall formed integral with a housing
which receives a wounded portion of a spring. The free end of the spring is fixed
to a front stop which extends along the front edge of a shelf.
[0007] EP 0 337 340 discloses a shelf divider system comprising a divider wall mountable in a channel
member secured to the front of a shelf. A spring-urged sled is slidably mounted on
a track having a pair of rails integral with the divider shaft. In one embodiment,
the operationally mounted divider wall is vertically oriented and the sled extends
horizontally therefrom so that displayed merchandise resets directly on the shelf
surface but is automatically urged forwardly by the retracted sled. In another embodiment,
the track guiding the sled rests on the shelf such that it provides the supporting
surface for displayed merchandise and a vertical divider wall is integrally formed
with the track. By mounting the product urging sled slidable along a track, the guidance
of the product urging member is enhanced which improves the functioning of the feeder,
keeps the row of products in order and enhances the visual appearance of the installation
and stored products.
[0008] For avoiding the drawer effect and achieving a satisfactory guidance of the product
urging sled, it is desirable that the distances between the guiding contact surfaces
of the sled and the track are longer in the longitudinal direction than in the transverse
direction. At the same time it is desirable to fully utilize the available space on
the shelf, in the feeder device's longitudinal direction for storage of products.
For this reason it is desirable that the sled does not extend excessively behind the
product urging support surface of the sled.
[0009] US 2016/0324334 A1 discloses a feeder device intended for bottles which comprises a sled that is guided
by a track and urged forwardly by a wound spring, the free end of which is fixed to
a front portion of the track. The sled comprises a vertical back support wall which
urges the bottles forwardly by contacting a rear portion of the rearmost bottle. The
sled further comprises a horizontal bottom wall which extends forwardly from the lower
edge of the back support wall. By this means, the longitudinal distance along which
the sled is guidedely in contact with the track may be increased by arranging at least
a portion of these contact surfaces in front of the vertical wall, at the lower side
of the bottom wall. At the same time the upper surface of the bottom wall may be used
for supporting at least the rearmost product, such that a comparatively great portion
of the length of the sled may be used for housing products.
[0010] This type of feeder provides good functionality for bottles and other types of products
being comparatively rigid and having a comparatively large lower support surface.
However, for other types of products and packages this type of feeder exhibits some
major disadvantages.
[0011] Fig. 1 illustrates a known feeder device of generally the same type as described
in
US 2016/0324334 A1. In fig. 1 this feeder device 1 is used for feeding pouch packages. The feeder device
1 comprises an elongate track 2 which is attachable to a front profile 3 extending
along the front edge of a shelf S. A front stop 4 is also fixed to the front profile
3 and arranged to prevent pouch packages P being fed forwardly by the feeder device
to fall off from the shelf S. The feeder device further comprises a sled which slidably
fixed to the track 2. For this purpose, the track exhibits transversely protruding
rails 6 which extend on both sides of the track along essentially its entire length.
The sled 5 comprises corresponding guide flanges 7 forming guide grooves (not visible)
which receive a portion of a respective rail 6 for rectilinear guiding of the sled
5 along the track 2. The sled further comprises a back support wall 8 which is arranged
to contact a rear portion of the rearmost of a number of packages arranged one after
the other in a row. A support bottom 9 extends forwardly from the lower edge of the
back support wall 8 and is arranged to support the bottom of a few of the rear packages
in the row of packages. For achieving satisfactory guidance of the sled 5, the guide
flanges 7 and guide grooves extend forwardly from the rear end of the sled almost
all the way to the front end of the support bottom 9.
[0012] The feeder device 1 also comprises a wound spring (not shown), the wound portion
of which is housed behind the rear support wall 8 and the free end of which is fixed
to the front end of the track 2. The spring thus urges the sled 5 forwardly along
the track 2. As long as there are a number of packages placed between the front stop
4 and the rear support wall 8, the normal forces created by the packages will maintain
the sled 5 in position. When a front most package is picked out, the sled will move
forwardly pushing the row of packages forwardly such that the emptied space left after
the picked package is filled by the next package in the row.
[0013] Now, as seen in fig. 1, this known arrangement causes some problems when the feeder
device is used for comparatively thin pouch packages. When the sled 5 has reached
its forward end position shown in fig. 1 and the remaining number of packages do not
occupy the entire distance between the front stop 4 and the back support wall 8, the
remaining packages will have a tendency to lean or tilt forward such that the upper
portion of at least the front most remaining package will extend out in front of the
front stop 4. This may result in that persons or shopping carts passing by make contact
with the tilted packages and causes the packages to unintentionally fall off from
the shelf. Naturally, this is most unwanted and causes disorder in the shop as well
as additional labour for putting the packages back on the shelf and it may even lead
to that the packages are damaged such that they must be discarded. These problems
occur not only for pouch packages but also for rigid packages where the thickness
of the packages is smaller than the distance between the front stop 4 and the back
support wall 8, when the sled is in its forward end position.
[0014] At pouch packages and other comparatively soft package, an additional problem resides
in that such soft packages, when tilted forwardly, have a tendency to be bent along
the contact line with the upper edge of the front stop 4. Such bending of the packages
causes an unpleasant appearance and may even hinder customers from reading printed
matter on the packages or otherwise to identify the products.
[0015] The problems described above also occur at similar feeder devices where the guide
track has been omitted. At such feeder devices the back support wall may rest directly
on the shelf and may be forwardly urged by similar or corresponding spring means.
In order for the back support wall to be maintained in an upright position, it is
important that the lower support surface being in contact with the shelf is large
enough for avoiding tipping over of the back support wall. Just as for guided sleds
described above, it is desirable that the lower support surface of the back support
wall extends forwardly from the back support wall in order not to decrease the available
space of the shelf when the back support wall is in its rear most position. For this
reason, also such back support walls which are not guided by a track normally exhibits
a support bottom which extends forwardly from the lower edge of the back support wall.
The forwardly protruding support bottom provides a satisfactory support for the back
support wall on the shelf but also results in that the last remaining thin and / or
soft packages resting on the upper side of the support bottom will experience the
same problems of tilting, falling and bending as described above.
SUMMARY
[0016] An object of the invention of the present disclosure to provide a an enhanced feeder
device for feeding products to the front of a shelf.
[0017] Another object is to provide a feeder device which at use reduces the risk of comparatively
soft products or packages fall off the shelf.
[0018] A further object is to provide such a feeder device which enhances the visibility
and identification of products or packages being fed.
[0019] A still further object is to provide such a feeder device which enhances the visual
appearance of the shelf as well as products and packages stored thereon.
[0020] Yet another object is to provide such a feeder device which is simple in construction
and reliable in use.
[0021] These and other objects are provided by a feeder device of the type indicated in
the introductory portion of claim 1, which feeder device exhibit the special technical
features defined in claim 1's characterizing portion. The feeder device is configured
for being mounted on a shelf for feeding successive products arranged one after the
other in a row on the shelf to the front of the shelf. It comprises a sled which comprises
a back support wall arranged to contact a rear portion of a rearmost product in the
row and a support bottom which extends forwardly from the back support wall and is
arranged to support the bottom of at least one product. A first spring is connected
to the sled and arranged to urge the sled forwardly towards a front of the shelf.
The sled further comprises a pusher which is arranged to urge a lower portion of a
product placed on the support bottom forwardly relative to the sled.
[0022] The pusher thus forces products and packages placed on the bottom wall forwardly
such that they will make contact with a front stop arranged at the front of the shelf.
At products and packages having a dimension in the longitudinal direction of the feeder
device which is smaller than the distance between the front stop and the back support
wall, in the front most position of the sled, any space between the front most product
and the front stop is eliminated. By this means, forward tilting of last remaining
products is avoided and the problems connected thereto and described above are eliminated.
[0023] The pusher may be urged forwardly by means of an elastic member.
[0024] The elastic member may be a spring.
[0025] The spring may be said first spring.
[0026] The pusher may be hinged to the back support wall.
[0027] The feeder device may further comprise an elongated guide member which is configured
for extending longitudinally backwards from the front of the shelf when the device
is mounted and the sled may be slidably and guidedly connected to the guide member
such that the sled can slide longitudinally along the elongated guide member.
[0028] The sled and the guide member may be provided with cooperating guide means configured
to guide the sled along the guide member and wherein at least one of said guide means
is arranged at the support bottom.
[0029] The cooperating guide means may be separated in the longitudinal and the transverse
direction of the guide member and at least one longitudinal separation distance may
be then equal to or greater than at least one transverse separation distance.
[0030] The guide means may comprise at least two longitudinally extending guide flanges
arranged side by side at the sled and wherein the longitudinal extension of the guide
flanges is equal to or greater than the transvers distance between them.
[0031] The invention also relates to a shelf managing system comprising a front profile
arranged to be fixed to the front edge of a shelf, a front stop and a feeder device
as described above.
[0032] Further objectives and advantages of the invention will appear from the following

DETAILED DESCRIPTION
[0035] Embodiments will now be described more fully hereinafter and with reference to the
accompanying drawings, in which certain embodiments are shown. However, other embodiments
in many different forms are possible within the scope of the present disclosure. Rather,
the following embodiments are provided by way of example so that this disclosure will
be thorough and complete, and will fully convey the scope of the disclosure to those
skilled in the art. Like numbers refer to like elements throughout the description.
[0036] The feeder device 100 shown in figs. 2-4c comprises an elongate guide member 10,
a sled 30 and a spring 60. The feeder device is positioned on a shelf S and attached
to an elongate front profile 200 which is fixed to the shelf by means of a double
sided adhesive tape (not shown) the front profile 200 extend along the front edge
of the shelf and exhibits a constant cross section with a T-shaped flange 201 protruding
upwards from a base web 202.
[0037] In the shown example, the guide member 10 comprises a front portion having a forwardly
protruding fixation member 12 which defines a downwardly open fixation grove which
receives the T-shaped flange 201 when the fixation member 12 has been snap mounted
onto the front profile 200. However, the guide member may be fixed to the shelf in
many different ways, such as by adhesives, magnets, screws or the like. Normally,
it is desirable that the feeding device is easy to remove, re-mount and displace along
the shelf for adjusting the shelf lay-out or planogram for different products. For
this purpose, the feeder device advantageously forms part of a shelf management system
which also comprises fixation means such as a front profile, divider walls, front
stops and other shelf accessories such as label holders, flag holders and illumination
means. Typically, the shelf management system is designed such that the accessories
may easily be fixed and adjusted to any desired position along the shelf and the system
often comprises a front profile having engagement means for such adjustable fixation
of the accessories. The engagement means may vary in many different ways which are
known in the art and it is readily understood that the feeder device according to
the invention may be provided with any type of corresponding fixation means which
are not described further in detail here.
[0038] In the shown example the guide member 10 comprises three sections comprising a front
section 14, a mid section 16 and a rear section 18 which are provided with cooperating
engagement means (not shown) for attaching the sections one after the other in the
longitudinal direction. The front 14 and rear 18 sections are identical and comprise
the fixation member 12 for fixation to the front profile 200 and, when applicable,
an identical or similar rear profile. In the shown example the rear profile has been
dispensed with and the guide member is fixed to the shelf S merely by means of the
front profile and the engagement member 12 of the front section 14. The mid section
16 may be manufactured and delivered in different lengths, such that the guide member
10 and the feeder device 100 may easily be adapted to different shelf depths.
[0039] The assembled guide member 10 is generally plate shaped and exhibits a lower side
which rests on the shelf S when mounted and an upper side which supports the products
and the sled 30. On the upper side, two longitudinally extending first guide flanges
20, 22 are arranged along a respective side edge of the guide member 10. The cross
section of each first guide flange 20, 22 projects upwardly and transversely outwards
passed the respective side edge of the guide member 10. Two support ribs 24, 26 extend
in parallel, side by side longitudinally along the guide member, between the guide
flanges 20, 22.
[0040] The sled 30 comprises a vertical back support wall 32 with a forwardly facing rectangular
support surface and two generally triangular side walls 34, 36 extending perpendicularly
backwards from respective side edges of the back support wall 32. Two spring housing
walls 36 (only one shown) extend backwards from the rear side of the back support
wall, in parallel with and between the side walls 34, 36, such as to define a spring
receiving space them between. A hinge flange 40 extends backwards, between the side
walls 24, 26 from the upper edge of the back support wall 32. The back support wall
further exhibits two through penetrating slits 33 arranged vertically, in parallel
and debouching in the spring receiving space.
[0041] The sled further comprises a pusher 42 which is hinged to the upper edge of the back
support wall 32. The pusher 42 comprises a rectangular pusher plate 44 with two generally
J-shaped hinge hooks 46 extending backwards from its upper edge. Each hinge hook 46
hingedly receives a portion of the hinge flange 40. Two curved spring legs 48 extend
backwards from the pusher plate 44 through a respective slit 33 into the spring receiving
space.
[0042] The sled 30 also comprises a support bottom 50 which extends horizontally forwards
from the lower edge of the back support wall 32, The support bottom exhibits a number
of longitudinally extending and upwardly projecting support ribs.
[0043] The guide member 10 and the sled 30 comprise cooperating guide means. In the shown
example these guide means comprise the first guide flanges 20, 22 of the guide member
and two corresponding L-shaped longitudinally extending second guide flanges 54, 56
projecting downwards and toward each other from the lower side of the support bottom
50. The second guide flanges 54, 56, thus define a respective guide grove which faces
each other and which receive a respective first guide flange 20, 22. The second guide
flanges 54, 56 are separated by a first distance in the transverse direction. In order
to enhance guiding of the sled 30 along the guide member 10 and to avoid the drawer
effect the second the longitudinal separation of the front most and rearmost guide
surface portions should be equal or greater than the first, transverse separation
distance. In the shown example, this is accomplished by that the second guide flanges
54, 56 extend over essentially the entire longitudinal length of the sled, which length
is greater than the first transvers separation distance.
[0044] In a not shown alternative embodiment the second guide flanges 54, 56 may be exchanged
by two or more pairs of transversely separated guide means, such as guide tabs or
the like which cooperate with longitudinally arranged guide means on the guide member.
In such case the longitudinal distance between the front most and rearmost pair of
guide means on the sled should preferably be separated by a distance which is greater
than the transverse distance between the guide means in each pair.
[0045] An advantage of the feeder device according to the invention is that the support
bottom 50, which extends forwardly from the back support wall 32 may be utilized for
carrying the sled's 30 guide means. By this means the longitudinal distance between
front and rear most guide means may be increased without the need of excessively extending
the sled rearwards behind the back support wall 32. In this way a maximum portion
of the shelf's depth may be used for storage of products.
[0046] The feeder device also comprises a spring 60 for urging the sled 30 forwardly along
the guide member 10. In the shown example the spring 60 is a flat spiral spring of
the clock spring type. The spring 60 comprises a wound portion 62 and an elastically
extendable and retractable extended portion with a free end 64. The wound portion
62 is housed and maintained in the spring receiving space, between the spring housing
walls 36. The extended portion extends under the support bottom 50 and between the
support ribs 24, 26 of the guide member 10. The transvers distance between the support
ribs 24, 26 is essentially equal to the width of the spring, thus maintaining the
extended portion of the spring 60 aligned with central axis of the guide member 10.
The free end 64 is thread through a spring slit 28 arranged in proximity to the fixation
member 12 and fixed to the guide member 10.
[0047] With reference to figs. 4a-c, and 5a-b, the functioning of the feeder device 100
will now be explained. In fig. 5a the feeder device 100 is shown in a fully reward
extended position on the shelf S and loaded with a number of pouch packages P arranged
one after the other in a longitudinal row. In the shown example, the thickness of
the packages allows the two rearmost packages to be supported on the support bottom
of the sled 30.
[0048] The feeder device 100 is fixed to a front profile 200 as described above and a front
stop 210 is also fixed to the front profile by a similar snap fixation. The front
stop comprises a transparent stop plate which extends vertically upwards and in parallel
with the front profile. The front stop 210 is positioned in front of the sled 30 and
the pouch packages P.
[0049] In this reward extended position the spring 60 urges the sled 30 forwardly whereby
the back support wall 32 and the pusher plate 44 exerts a forwardly directed force
to the pouch packages P. The front most package P rests against the front stop 210,
whereby the packages P are compressed and exert a normal force to the pusher plate
44. The spring legs 58 rests against the wound portion of the spring which radially
urges the pusher plate 44 to rotate clockwise (as seen in the figures) about a hinge
axis defined by the hinge flange 40. However, the normal force of the row of packages
P is greater than the spring force applied to the spring legs 48 and the pusher plate
44, such that the pusher plate 44 is maintained in a vertical position in parallel
with and resting against the back support wall 32.
[0050] When the front most package P is picked out from the shelf such that an empty space
is created behind the front stop 210, the spring 60 is elastically wound, such that
the extended portion is retracted and the sled 30 is urged forwardly pushing the row
of packages P forward relative to the guide member 10 and the shelf S. The lower edges
of the packages P rest on the guide member's 10 comparatively narrow guide flanges
20, 22 and support ribs 24, 26 such that the friction between the packages P and guide
member 10 is reduced, thereby enhancing feeding action of the feeder device 100.
[0051] In fig. 5a all packages except the previously rear most package P have been picked
out and the sled 30 has thereby been displace forwardly to its front most position.
In this position the front edge of the support bottom 50 rests against the front stop
210, thereby preventing further forward displacement of the sled 30. At picking out
of the second last package P the pusher plate is rotated clockwise as illustrated
in figs. 4a to 4c. When the second last package is picked out, further forward movement
of the sled 30 is prevented by the front edge of the support bottom 50 making contact
with the front stop 210. Since the thickness of the remaining last package is smaller
than the longitudinal length of the support bottom and thereby the distance between
the back support wall 32 and the front stop 210, the remaining package will not exert
any normal force on the pusher plate 44. By this means the radial spring force exerted
by the springs wound portion on the spring legs 48 will cause the pusher plate to
rotate clockwise about the hinge axis defined by the hinge flange 40. The lower portion
of the pusher plate 44 thereby makes contact with a lower portion of the remaining
package P and displaces the lower portion of the package forwardly relative to the
now stationary support bottom 50 and the front stop 210. During this displacement
the narrow support ribs 52 on the support bottom reduces the friction and facilitates
the forward displacement. During the forward displacement of the lower portion of
the remaining package P, a mid portion of the package rests against an upper portion
of the front stop 210. The displacement of the lower portion will thereby result in
that the package is rotated clockwise (as seen I the figures) such that the entire
remaining package P straighten up to an essentially vertical orientation as illustrated
in fig 5b.
[0052] By this means any forward tilting of the package is eliminated and the risk of any
upper portion of the package extending out in front of the front support is greatly
reduced. Thereby the problems occurring at the prior art as described above is eliminated
or at least greatly reduced.
[0053] The present disclosure has mainly been described above with reference to a few embodiments.
However, as is readily appreciated by a person skilled in the art, other embodiments
than the ones disclosed above are equally possible within the scope of the present
disclosure, as defined by the appended patent claims. For example, in a non shown
embodiment the pusher plate is urged forwardly relative to the support bottom by means
of a second spring or other elastic means such as an elastic pad which is arranged
between the back support wall and the pusher plate. The pusher need not be hinged
to the back support wall but nay instead comprise any type of pusher plate or the
like which is arranged in front of the lower portion of the back support wall and
which is urged to be linearly displace forwardly. As indicated above the cooperating
guide means of the sled and the guide member may take many other forms as long as
they provide a satisfactory guidance of the sled along the guide member. The movement
of the sled may be accomplished by other means than a flat wound spring, e.g. by an
extension spring or an elastically loaded rack and pinion drive. At further not shown
embodiments, the guide member is omitted. At such embodiments, the sled comprising
the back support wall and the support bottom rests directly on the shelf and is urged
forwardly by a suitable spring means such as a wound spring or similar. The sled may
be guided merely by the forwardly urging action of the spring means. It is however
also possible that the sled, at such embodiments, is guided by divider walls or other
shelf accessories that extend rearward from the front edge of the shelf in parallel
with the movement path of the sled at either or both sides of the sled.
