Method for a treatment of ironing and similar of clothing articles, particularly uncreased-style trousers and corresponding apparatus

Description

Field of Application

[0001] The present invention relates to a method for a treatment of ironing and similar of clothing articles, particularly uncreased-style trousers.

[0002] Specifically, the invention relates to a method for a treatment of ironing and similar of clothing articles, particularly uncreased-style trousers, by means of a plurality of treating heads active on said clothing articles, these being held by a plurality of grip elements.

[0003] The invention further relates to an apparatus for a treatment of ironing and similar of clothing articles, particularly uncreased-style trousers, of the type comprising a plurality of working heads and a plurality of gripp elements of the article to be treated.

[0004] Although not limited to, the invention relates to a method of ironing through blowing and steaming uncreased-style trousers and the following description of this field of application is given for convenience of explanation only.

Prior Art

[0005] As it is well known, clothing article treatment, particularly uncreased-style trouser ironing, is industrially performed by means of proper machines that are equipped with working heads operative to discharge steam on the articles.

[0006] Conventional ironing machines also comprise grip elements or grippers holding clothing articles positioned at a working head.

[0007] In particular, an operator loads a clothing article in the grippers, and remove the clothing article by release of the grippers at the end of the ironing treatment.

[0008] In order to increase the number of articles treated per time unit, it is also known to provide a system for treating clothing articles with a plurality of treating machines controlled by an operator, who loads a clothing article on a machine, while another clothing article is being treated by another machine, and then unloaded once the ironing treatment is ended, in such a way as to minimize waiting times.

[0009] However, such a treating system is not little automated, because it depends on the operator's ability to load and unload quickly the clothing articles on/down the machines.

[0010] A system has also been suggested wherein a plurality of machines, each including a working head and grippers, are installed on a turntable type of structure.

[0011] US 6449369 describes such a machine.

[0012] A single operator loads a clothing article to be treated on the grippers of a machine when this one passes for treating by the machine as the latter moves past him, and the treated article is then picked up by some automated means. During the turntable rotation, the clothing article moves from a loading station to an unloading station through a number of other stations where it can be treated as desired.

[0013] This prior construction, although advantageous on several counts, especially in that it allows a higher degree of automation, is made complicated by the orbiting machines either involving the provision of steam generators to serve each machine individually, or of elaborate and expensive rotary pipe connections between the machines and a common steam generator.

[0014] The underlying technical problem of this invention is to provide a method and an apparatus for ironing clothing articles, particularly uncreased-style trousers, which while meeting all of the treating requirements, can overcome the limitations that beset prior arrangements.

Summary of the invention

[0015] The resolution idea on which this invention stands is one of providing for the clothing articles to be moved around and the working heads held stationary for treating the articles.

[0016] Based on the above idea, the technical problem is solved by a method for a treatment of ironing and similar of clothing articles, particularly uncreased-style trousers by having a plurality of working heads arranged to act on said clothing articles while they are held in a plurality of grippers, characterized in that it comprises mounting said plurality of grippers on a carousel, and rotating the carousel relative to said plurality of working heads maintained stationary to successively take each said clothing article under each working head of said plurality of working heads for treating.

[0017] The problem is further solved by an apparatus for a treatment of ironing and similar of clothing articles, particularly uncreased-style trousers, which apparatus comprises a plurality of working heads and a plurality of grippers in which clothing articles to be treated are gripped, and is characterized in that it comprises a carousel mounted in a support frame and carrying said plurality of grippers, and that the carousel is rotatable relative to said plurality of working heads, which are instead maintained stationary on said frame, thereby to take each said clothing articles in succession under each working head of said plurality of working heads for treating.

[0018] The features and advantages of the method and apparatus according to the invention should become more clearly apparent from the following description of embodiments thereof, given by way of example and not of limitation with reference to the accompanying drawings.

Brief description of the drawings

[0019] In the drawings:

Figure 1 is a schematic perspective view of a clothing treating apparatus embodying this invention; and

Figures 2 and 3 are respective longitudinal and transverse cross-sectional views in perspective of the apparatus shown in Figure 1.

Detailed description

[0020] With reference to the drawings, in particular to Figure 1 thereof, an apparatus for ironing clothing articles, particularly uncreased-style trousers, is shown generally at 1.

[0021] The apparatus 1 comprises a support frame 2, which is preferably a metal construction extending between two opposite decks, specifically a lower or base deck 3 and an upper deck 4, the decks being connected rigidly together by peripheral uprights 5.

[0022] The frame 2 has a generally prismatic shape that grows vertically around a vertical axis XX.

[0023] Mounted fixedly on the upper deck 4 of the frame 2 are a plurality - eight in the example shown - of working heads, as follows:

a first head 11 of article loading, i.e. an article loading head;

a second head 12 of steaming and/or blowing, i.e a steaming and/or blowing head 12;

third, fourth and fifth heads 13, 14 and 15 of steaming and/or blowing, i.e. steaming and/or blowing heads, which are essentially similar to the second steaming and/or blowing head 12;

a sixth head 16 of article cooling and stabilizing, i.e. an article cooling and stabilizing head;

a seventh head 17 of article unloading, i.e. an article unloading head;

an eighth head 18 of spare loading, i.e. a spare loading head.

[0024] Preferably, the plurality of working heads are mounted on the frame 2 in a circular array around a set vertical axis X-X, at equiangular distances from each other.

[0025] The steaming and/or blowing heads include each a steaming assembly and a blowing assembly. Each head may optionally be provided with a cooling assembly as well.

[0026] In particular, the steaming assemblies are advantageously supplied steam from a common steam generator, not shown in the Figure. The steam generator is connected to the steaming assemblies by steam supply lines 6 and an associated header 7, as shown schematically in Figure 2.

[0027] In particular, respective connection lines lead to the steaming assemblies from the header 7.

[0028] The apparatus 1 also has an air intake line 8 connected to a conventional source, such as a pressurized air source, not shown. The air intake line 8 branches off by a line 9 to a distributor 10 and to a rotary pipe connector 20. Air supply lines radiate from the distributor 10 to the stationary working heads, the rotary pipe connector 20 being connected to further lines to be described.

[0029] In particular, suitable valve means, e.g. gate valves, generally shown at 7A may be arranged to control the delivery of steam from the steaming heads, and to cut it off altogether as the tubular support is rotated forward one step.

[0030] To hold the trousers for treating, the apparatus 1 of the invention is provided with a plurality of grippers 21, which are all identical and adapted to grip respective pairs of the trousers being treated. In particular, each gripper 21 has a respective stretcher appropriate to grip the trousers at the waist end and a clamp 23 appropriate to hold the trousers bottom ends closed, the trousers being thus held in an upright position.

[0031] Said plurality of grippers 21 are mounted on a carousel that comprises a tubular support 24 having an axis XX. The tubular support 24 is mounted for pivotal movement about the axis XX of the frame 2. In particular, the tubular support 24 bears for pivotal movement on a bearing block 25, which bearing block is secured within the uprights 5 on the lower deck 3 of the frame 2 and reaches upwards just short of the upper deck 4, it being designed to take the individual grippers 21 under the working heads. In other words, the combined tubular support 24 and bearing block 25 define a carousel that is rotatable relative to the working heads and carries a plurality of grippers 21.

[0032] The stretcher and clamp 23 of each gripper 21 are supplied air through lines 26 that lead out from said rotary connection 20.

[0033] As far as the electric power supply is connected, electric cables 27 are led to the area of the upper deck 4 and connected to the individual working heads over a branch strip 27A.

[0034] Power is also supplied to the area of the lower deck 3 through a rotary connection 28 from which electric cables 29 radiate to each gripper 21.

[0035] It should be noted that, concentrically with the bearing block 25, an internal ring gear 30 is attached to the tubular support 24 for mesh engagement by its teeth 31 with an idler 32, in turn meshing with a drive gear 32A that is keyed onto a shaft 36 of a conventional electric motor 37, the motor being mounted fixedly to a plate 33 and rotating the tubular support 24 stepwise, as shown schematically in Figure 3.

[0036] It should be noted that the apparatus 1 of the invention has a station P1 located near and opposite the first working head 11 for loading the trousers to be treated, and has a station P2 near and opposite the eighth working head 18 for unloading the treated trousers. In the example of Figure 1, the loading station P1 would have human attendance, and the unloading station P2 includes a belt conveyor 34 and a chute 35 mounted to the lower deck 4 and sloping down to the belt conveyor 34.

[0037] The operation of the apparatus 1 in treating trousers articles as desired will now be described.

[0038] At the loading station P1, the trousers are manually loaded, one pair at a time, in the grippers 21, which are maintained stationary therein and the trousers are here treated by the first working head 11.

[0039] On completion of the operation, the tubular support 24 is rotated one step to take the trousers under the second working head for further treating, and so forth to the eighth working head 18, where the final treating of the trousers takes place and the trousers are ultimately removed over the chute 35.

[0040] In operation, the valve means 7A are operated to control the amount of steam being delivered, or to cut off the steam supply as the tubular support is advanced one step.

[0041] The apparatus of this invention has a major advantage in that its construction is simple, since it has a moving portion only in the area devoted to holding the trousers, and is held stationary with its major portion, represented by the working heads.

[0042] A second, not less important advantage of the apparatus of the invention is the unique quality of the trousers product that is achieved by having the trousers treated in a motionless condition. In fact, no uneveness is experienced in the steam and/or air flow delivered to the trousers being treated, such as would otherwise result in one side of the trousers showing a different final treatment from the other side.

[0043] Also noteworthy is that the simple construction of the apparatus makes for high expectations in the respect of reliable operation and long maintenance-free life of same.

[0044] It should be further noted that the working heads of the apparatus of the invention are multi-functional, in that it is possible to equip them with steaming, blowing and cooling assemblies. The apparatus is therefore highly versatile, flexible, and adaptable to meet different requirements of clothing treating.

[0045] Finally, the apparatus of the invention affords energy usage benefits, which arise from the delivery of steam being controllable, as well as from the steam supply cut-off feature as the tubular support is to be rotated forward one step.
