SET AND METHOD FOR DELIVERING A STACK OF ROOF COVERING PANELS AT A LOCATION OF USE

Description

[0001] The invention relates to a set for delivering at a location of use a stack of roof covering panels which is formed at a stacking location remote from the location of use. These are particularly, though not exclusively, corrugated panels. Arranging roof covering panels on a roof can be heavy work. The panels, which usually each weigh several tens of kilos, have to be lifted up to the roof and there be arranged at a correct location and with a correct orientation.

[0002] It is an object of the invention to at least partially lighten this heavy work. It is a particular object of the invention to provide a set for picking up and transporting a stack of roof covering panels whereby a stack of roof covering panels can be displaced upward and whereby the panels can be presented one by one at a suitable height and location.

[0003] Documents JP H05 330779, NL 1 027 861, EP 1 375 397, and WO 2010/080023 all disclose a device for lifting reinforcement mats. Document DE 44 02 641 discloses a device for gripping a pile of stones.

[0004] Document US 3 983 676 discloses an apparatus for automatically applying and securing roofing panels to the purlins of a steel frame building. A wheeled cart containing a plurality of roofing panels rolls longitudinally of the purlins of the building and automatically deposits roofing panels on the purlins. An automatic fastening device is provided to secure the panels to the purlins in synchronism with the deposit thereof on the purlins.

[0005] The invention is defined by a set according to claim 1. The stack can be formed in efficient manner at a stacking location, for instance in or at a production facility for the panels. From there, the stack can be transported to the area surrounding the location of use, for instance a construction site where a roof has to be placed on a building, and the stack can be picked up by the carrier device. The carrier device carries the stack of panels to the location of use, for instance a roof construction for finishing, where the panels to be used are taken from the stack.

[0006] The carrier device comprises a number of pairs of co-acting carrier elements, wherein at least one pair of carrier elements is in each case configured to carry one roof covering panel of the stack of roof covering panels at a time; and drive means for driving the pairs of carrier elements for presenting one roof covering panel of the stack of roof covering panels at a time.

[0007] The carrier device can be displaced upward as a whole, for instance by lifting or hoisting, wherein an individual roof covering panel can in each case be presented to a user at any desired height and/or at any desired location and/or at any desired moment by driving the carrier elements. Because the roof covering panels are displaced upward as a stack, presenting each individual roof covering panel can take place relatively quickly. The user can in this way process the roof covering panels and arrange them on the roof in relatively rapid and/or easy and/or simple manner.

[0008] Presenting is understood here to mean that the carrier device releases, delivers or makes available in other manner one roof covering panel at a time.

[0009] The drive means can be configured such that at least one pair of carrier elements can in each case be driven individually for the purpose of presenting the one roof covering panel at a time, which is carried by this pair of carrier elements. If a plurality of pairs of carrier elements carry one roof covering panel, all the pairs of carrier elements carrying this roof covering panel can be driven simultaneously.

[0010] The drive means can alternatively be configured such that all carrier elements are driven simultaneously, wherein one roof covering panel is presented at a time.

[0011] The drive means can for instance comprise a single motor, and a transmission for distributing the drive force over the carrier elements of each pair. The motor can for instance be driven electrically, for instance by the mains power supply or a battery. The drive means can alternatively be driven manually, wherein the drive means can optionally comprise a manually drivable handle or the like.

[0012] The carrier elements of each pair are arranged on at least two carrier members disposed at a mutual distance, which carrier members can be disposed on either side of the stack of roof covering panels for carrying during use of the carrier device. Using the carrier elements arranged on the carrier members, the stack of roof covering panels can be carried or supported on either side thereof by the carrier elements. Each roof covering panel is in this way carried or supported by at least two carrier elements on either side of the roof covering panel, so that the roof covering panels can be carried in stable manner.

[0013] In another embodiment of the set the carrier elements of each pair are movable toward and away from each other in a first direction, which is substantially perpendicular to a height direction of the stack. The carrier elements can thus be moved between a first position, in which they are situated at a distance from a stack for carrying, and a second position in which the carrier elements extend in each case between two roof covering panels, which adjoin in longitudinal direction of the stack, for the purpose of carrying one roof covering panel at a time.

[0014] Using the displaceable carrier elements or the at least one displaceable carrier member, the carrier elements can be disposed adjacently of a stack of roof covering panels in simple manner when the carrier elements are in their first position, wherein the carrier elements can then be displaced to their second position for the purpose of carrying the roof covering panels.

[0015] The two carrier members are displaceable relative to each other in a direction toward and away from each other. One of the two carrier members can here be displaceable, or both carrier members can be displaceable.

[0016] When the carrier elements are arranged on carrier members, wherein at least one carrier member is displaceable, the distance between opposite carrier elements disposed on either side is in the first position of the carrier elements greater than a width dimension of the stack of roof covering panels. The carrier members with carrier elements can in this way be disposed in simple manner on either side of a stack of roof covering panels for carrying. The carrier elements can then be displaced to their second position, in which second position the distance between opposite carrier elements disposed on either side is smaller than the width dimension of the stack of roof covering panels, so that the carrier elements extend between and carry the roof covering panels.

[0017] In yet another embodiment of the set the pairs of carrier elements or the carrier members are displaceable in a second direction which is substantially parallel to the height direction of the stack for the purpose of presenting one roof covering panel at a time. Because the carrier elements or carrier members are displaceable in the second direction during use of the device, the roof covering panels can be displaced substantially in the direction of the user and can thereby be presented one by one in simple manner.

[0018] It is noted that the carrier elements or the carrier members can optionally be displaceable exclusively in the second direction and not in the first direction. "First" and "second" must therefore be understood here only as distinguishing and indicating the directions, and not limitatively.

[0019] When the carrier elements of each pair extend on either side of a stack for carrying, so that two or more carrier elements in each case carry or support one roof covering panel, it is preferred to simultaneously displace the two or more carrier elements which in each case carry this roof covering panel.

[0020] In yet another embodiment of the assembly the carrier members each comprise an endless conveyor belt which is disposed parallel to the height direction of the stack for carrying and which can be driven in the second direction. Using the carrier members embodied as endless conveyor belts, the carrier elements can be displaced in the second direction in simple manner by driving the conveyor belts in the second direction. The carrier elements can thus be displaced substantially from and to a user in simple manner.

[0021] Another advantage of such carrier members embodied as endless conveyor belts is that the carrier elements automatically retract around a reversing point or reversing zone of the conveyor belts in substantially the first direction in a direction remote from the stack of roof covering panels. Due to the retracting displacement of the carrier elements, the distance between at least two opposite carrier elements situated at the reversing point and disposed on either side of the stack is automatically greater, whereby the carrier elements move away from under the roof covering panel which they are carrying and thereby deliver this roof covering panel to a user in simple manner. The conveyor belts can in each case be displaced over a short distance, particularly over substantially the distance between two adjoining carrier elements on one conveyor belt, so that one roof covering panel can be delivered at a time. It is noted that the distance is particularly short in relation to the length of each conveyor belt.

[0022] In yet another embodiment of the set the carrier elements of each pair can be moved apart individually in the first direction for the purpose of presenting one roof covering panel at a time. By displacing the carrier elements from their second to their first position, one roof covering panel is presented at a time. When a plurality of carrier elements carry one roof covering panel, they can be displaced together in the first direction from their second position to their first position.

[0023] In practical manner the device can comprise a frame which carries the carrier elements, the drive means and optionally the carrier members. The frame can for instance be placed over a stack of roof covering panels, particularly when the carrier elements are in their first position, wherein the carrier elements can then move to their second position. The device can in this way be disposed correctly in simple manner, and then pick up the stack.

[0024] In an embodiment the frame can comprise connecting means for connecting the frame to hoisting means for hoisting the frame. The device with stack can in this way be connected in simple manner to the hoisting means and be hoisted up thereby to a location of use on a roof.

[0025] In another embodiment of the set at least one of the carrier members is arranged in the sub-frame, which is movable in the frame in the first direction. The carrier member in question can thus be displaced in simple manner.

[0026] A secondary drive can be arranged for this purpose between the frame and the sub-frame. The secondary drive can be an electrical drive, but can also be a manual drive.

[0027] In order to enable the corrugated panels to be delivered at a desired position on a roof in simple manner, the assembly can be provided according to another embodiment with a means connected to the frame for moving the carrier device over a roof construction.

[0028] Because roofs often define an inclining surface, there is a danger of an upper edge of the corrugated panel coming into contact with the roof construction first during delivering, and the other side of the panel then falling hard and in uncontrolled manner on the roof construction. In order to prevent this, the assembly can be provided with means, connected on at least one side to the frame, for guiding a displacement of the presented roof covering panel from the carrier device to the roof construction.

[0029] According to an embodiment of the set, the stack forming means comprise at least two sets of spacers arranged on different sides of the stack for forming. An advantage of such stack forming means is that the carrier elements can be arranged between the roof covering panels, which are held at a mutual distance, in simple manner for the purpose of carrying the roof covering panels. The spacers can here in each case extend between two adjoining roof covering panels.

[0030] The two sets of spacers can for instance extend on two first opposite sides of a stack for carrying. When the stack is picked up by the device according to the set of the invention, the carrier elements can be arranged between the roof covering panels, for instance on said two first opposite sides of the stack for carrying, or conversely on the two other opposite sides of the stack for carrying.

[0031] The spacers can be embodied in any suitable manner. Each set of spacers can thus comprise a support which extends substantially in the height direction and on which the spacers are arranged with regular interspacing. In practical manner, the spacers can for instance comprise at least one elongate element with spacer elements extending substantially perpendicularly therefrom. As stated, the elongate element or the support can extend in the height direction of the stack during use, wherein the spacer elements in each case extend between two adjoining roof covering panels. The distance between two adjoining spacer elements can be chosen as desired for setting a suitable distance between two adjoining roof covering panels. The distance between two adjoining spacer elements can in particular be chosen to equal the distance between two adjoining carrier elements of the carrier device.

[0032] In an embodiment of the set the stack forming means comprise a base part to which the sets of spacers are releasably connected. By forming the stack of corrugated panels on the base part, the panels are held clear of the ground and the lowermost panel in the stack is protected from damage.

[0033] The stack forming means can in addition comprise a closing means to be placed on the stack and to be releasably connected to the spacers. With the combination of the base part, the supports and the closing part a construction is obtained which encloses the stack on all sides, whereby the stack is stable and can be transported in simple manner without the danger of panels falling from the stack.

[0034] The invention also relates to a method for delivering roof covering panels, such as corrugated panels, at a location of use, wherein a set according to the invention as described above is used. According to the invention, this method comprises of:

forming a stack of the roof covering panels at a stacking location remote from the location of use, picking up the formed stack of roof covering panels using a carrier device, transporting the carrier device with the stack of roof covering panels to the location of use and de-stacking the roof covering panels at the location of use, wherein the spacers are placed between each pair of successive roof covering panels during forming of the stack, and the roof covering panels are taken over from the spacers by the movable carrier elements of the carrier device during picking up of the stack,

wherein the carrier elements are situated in pairs on mutually opposite sides of the formed stack, and the carrier elements of each pair are moved toward each other in a first direction substantially perpendicularly of a height direction of the stack during picking up of the stack by displacing the at least two carrier members relative to each other in a direction towards each other. The stacking location can be situated in the area surrounding the location of use, so that the carrier device can be used to pick up the stack after forming and transport it to the location of use. As stated, the stacking location can however also be further removed from the location of use, and the stack can first be transported by a truck to the area surrounding the location of use, and then still be picked up there by the carrier device.

[0035] Variants of the method are described in the dependent claims 13-14.

[0036] The invention will be further elucidated with reference to figures shown in a drawing, in which:

Figures 1A, 1B and 2 show a carrier device 1 which forms part of a set according to a first embodiment of the invention. Device 1 comprises a frame 2 which can be hoisted up using hoisting means (not shown here) and then be placed over a stack of roof covering panels, in this case corrugated panels 3. Figures 1A and 1B show device 1 while it is placed partially over a stack of corrugated panels 3. Frame 2 can for instance comprise a number of lifting eyes 14 for connecting to the hoisting means, for instance a lifting crane.

[0037] In the shown example device 1 comprises four carrier members 4, here in the form of endless conveyor belts with carrier elements 5 arranged thereon. Carrier elements 5 are in this embodiment embodied as pins extending substantially perpendicularly from conveyor belts 4. Two conveyor belts 4 are in each case disposed on either side of the stack of corrugated panels 3 for carrying, so that each corrugated panel 3 can be carried by two pairs of mutually facing carrier elements 5. Two of the four conveyor belts 4 are in this example incorporated in a sub-frame 17 which is mounted in frame 2 for sliding along guides 18. Arranged between sub-frame 17 and frame 2 is a secondary drive, embodied in this example as a pair of shafts 15 mounted rotatably at the top and bottom of frame 2 and carrying scissor arms 16A, 16B. Scissor arms 16A, 16B on the upper and underside of frame 2 are connected here by vertical arms 16C. For rotating of shafts 15 a handle or lever (not shown here) can be provided, whereby the movement can be manually driven. It is otherwise also possible to envisage an electrical, hydraulic or pneumatic drive.

[0038] By sliding sub-frame 17, carrier members 4 and the carrier elements 5 arranged thereon are thus displaceable in a first direction 8, substantially perpendicularly of the height direction of the stack of corrugated panels 3 for carrying, between a first position in which carrier elements 5 are situated at a distance from a stack for carrying (see figures 1A and 1B) and a second position in which carrier elements 5 in each case extend between two corrugated panels 3, which adjoin in longitudinal direction of the stack, for the purpose of carrying one corrugated panel at a time (see figure 2). During this displacement the stack of corrugated panels 3 is shifted in the direction of fixed carrier members 4 so that the carrier elements 5 on that side of carrier device 1 also engage between the panels in stacks 3.

[0039] In the first position of carrier elements 5 the frame can be arranged over the stack of corrugated panels 3 in simple manner, as shown in figures 1A and 1B, and in the second position corrugated panels 3 are carried by device 1, as shown in figure 2. Corrugated panels 3 are stacked with some mutual distance, so that carrier elements 5 can be arranged therebetween in simple manner. Spacers are arranged for this purpose between corrugated panels 3, see also figure 3.

[0040] Conveyor belts 4 are drivable in a second direction 9 substantially parallel to the height direction of the stack of corrugated panels 3, so that the carrier elements 5 arranged thereon can deliver one corrugated panel 3 at a time. Carrier elements 5, which carry corrugated panels 3, are in the shown example displaceable in the direction of lower reversing rollers 10, around which reversing rollers 10 the conveyor belts 4 rotate. As shown in figure 2, the distance between opposite carrier elements 5, which opposite carrier elements 5 together carry one corrugated panel 3, increases close to reversing rollers 10 so that carrier elements 5 move away from under the corrugated panel 3 carried thereby and thus deliver the corrugated panel 3 in question on the underside of carrier device 1. In this manner it is possible to deliver one corrugated panel 3 at a time in simple manner, for instance on a roof construction, by driving endless conveyor belts 4 in each case over a short distance, particularly a short distance which is substantially equal to the distance between two adjoining carrier elements 5 on each conveyor belt 4.

[0041] Carrier device 1 could otherwise also be made suitable to supply panels to a location of use from the underside, for instance in the case of ceiling panels which are to be mounted on the underside of a roof construction. Conveyor belts 4 would in that case have to be driven in opposite direction. Drive means 19, which are now placed on the upper side of frame 2, would then also have to be accommodated elsewhere in frame 2 in order to leave the upper side of frame 2 clear.

[0042] Conveyor belts 4 can be driven over said short distance by a user at any desired moment. Conveyor belts 4 can alternatively be driven automatically, in each case with a time delay between two said short distances, for releasing one corrugated panel 3 at a time.

[0043] Conveyor belts 4 are driven by drive means 19. In the shown example the drive means comprise an electric motor 20 mounted on the upper side in frame 2 and coupled by a transmission 7 to two shafts 6A, 6B which are rotatable in opposing directions. Shaft 6A has a fixed length, while shaft 6B is a telescopic cardan shaft which can accommodate the displacement of sub-frame 17. Each shaft 6A, 6B is coupled by a right-angled transmission 21 to a transverse drive shaft 22, which carries the upper reversing rollers 23 of conveyor belts 4 at its ends. Device 1 can optionally comprise at least one battery 24 for driving motor 20 (figure 5) or can alternatively be provided with a plug for connecting motor 20 to the mains power supply. As further alternative conveyor belts 4 can be manually drivable. Device 1 can for instance comprise for this purpose a drive handle coupled to the conveyor belts.

[0044] Figure 3 shows means 25 for forming a stack of corrugated panels 3 according to an embodiment of the set according to the invention. Corrugated panels 3 are held at a mutual distance by spacers. The spacers each comprise an elongate, substantially slat-like, element or support 11 with substantially pin-like spacer elements 12 extending substantially perpendicularly from a longitudinal main plane thereof. Spacer elements 12 can in each case extend between two adjoining corrugated panels 3 for holding corrugated panels 3 at a mutual distance. The stack of corrugated panels 3 is arranged on a pallet or base part 13, to which supports 11 are releasably attached.

[0045] It is noted that spacer elements 12 are in figure 3 disposed on the same opposite sides as where carrier elements 5 extend. It is however also possible for spacer elements 12 to be arranged conversely on the other two opposite sides. This can possibly facilitate the picking up of stack 3 by device 1. As soon as carrier elements 5 have moved toward each other and stack 3 is carried by the device, supports 11 can be removed.

[0046] In an alternative embodiment of the set (figure 4) base part 13 of stack forming means 25 is embodied as a metal grid which rests on a ground surface on four feet 27. The four supports 11 of the spacers are placed on or into feet 27. Base part 13 has protruding stops 26 on which frame 2 of carrier device 1 comes to rest when stack 3 is picked up. Stack forming means 25 here also comprise a closing part 28 which is placed on stack 3 and which is connected to the upper sides of the four supports 11. Closing part 28 has two transverse bars 29 with outer ends which are received in vertical guide profiles 30 on the sides of frame 2 (figure 5). Base part 13 with feet 27, supports 11 of the spacers and closing part 28 together form a stable housing for the stack of panels 3, while stops 26 in combination with guide profiles 30 provide for a good enclosing of the stack in frame 2 of carrier device 1.

[0047] In this embodiment carrier device 1 differs slightly from the above shown and described device. In addition to the above discussed guide profiles 30, two handgrips 31 are also fixed to frame 2 to enable handling of carrier device 1 when hoisted. The secondary drive for siding sub-frame 17 is now further provided with three sets of scissor arms 16A, 16B, not only on the upper and underside of frame 2 but also halfway therebetween. The secondary drive is further provided here with a screw spindle 32 which is controlled by a hand wheel 33. By rotating hand wheel 33 sub-frame 17 is moved from its position shown in figure 6, in which carrier elements 5 lie clear of stack 3, to the position of figure 7, in which stack 3 has been shifted to a position against the fixed carrier members and the pairs of carrier elements 5 protrude into stack 3 on either side. This is shown in detail on enlarged scale in figure 8. In the position of figure 7 base part 13 has otherwise already been disconnected from stack 3, which is here carried by device 1.

[0048] When the stack of panels 3 has been received in carrier device 1, carrier device 1 can be hoisted by for instance a lifting crane to the location of use, for instance on a roof construction 34 which is being built (figure 9). In order to enable carrier device 1, which is still suspended from the lifting crane, to be moved uniformly over a roof construction 34 with little effort it is in the shown example equipped with moving means 35. Moving means 35 here comprise two blade wheels 36, each having a central recess 37. Blade wheels 36 are mounted rotatably in extenders 38.

[0049] In the shown example carrier device 1 is further provided with means 39 for guiding the movement of each individual roof covering panel P which is released by carrier elements 5 and delivered on roof 34. These guide means 39 here comprise a plate 40 which is mounted on the side of frame 2 furthest removed from roof construction 34. The position of plate 40 relative to frame 2 can be adjusted by extenders 41, from which hangs a hook 42 which can be hooked into an opening 43 of plate 40. This position is chosen such that each panel P lands on roof construction 34 in properly guided manner.

[0050] The set according to the invention and the method wherein this set is used thus make it possible to safely transfer heavy and large roof covering panels to a location of use on a roof in rapid, simple manner with little effort. In addition, the invention makes it possible to form stable stacks of such panels, which can be handled and transported easily, in rapid and simple manner.

[0051] It is further noted that the invention is not limited to the shown embodiments but also extends to variants within the scope of the appended claims.
