Description

Folding device comprising a folder and a labelling machine

Technical Field

The present patent application for industrial invention relates to a folding device comprising a folder and a labelling machine.

In the present invention, the labelling machine is a machine capable of moving and placing labels from a first position (preferably in a store) to a second position, wherein the folder of the folding device is adapted to fold the patches or pockets. And the patch or pocket is positioned continuously on the web by inserting a label applied by the labelling machine.

Although the description and the claims refer to labels, the labelling machine of the present invention may also be used to move and support any type of protective film, trimmings or inserts, suitable for being positioned under a folder.

The machine according to the invention may comprise, downstream of the folding device, a sewing device adapted to sew the pockets and the labels on the piece of fabric, wherein the pocket and the labels have been positioned by the folder and the labelling machine.

Background

Garments are known having labels sewn into the side edges of the pocket.

In order to sew the label on the side edge of the pocket, the operator must manually pick up the label from the area where it is stored, separating it from the other labels.

The operator must then position the label between the piece of fabric at the pocket to be folded and sewn and the lateral edge of the pocket not folded on the fabric, so that the label partially protrudes from the lateral edge of the pocket. It must be noted that in some cases the label is already folded.

Furthermore, it must be noted that the tag is currently inserted in the following way: when the folder moves backward, after folding the pocket, the pocket is folded on the board, a piece of fabric sheet is applied thereon without being completely adhered, and then the label is inserted with a jig. This fact makes the insertion difficult and risks causing problems on the folded edges of the pocket. In fact, in the event of contact, the folded edge of the pocket tends to move, thus losing the correct position for folding the pocket.

In addition to compromising the proper positioning of the pocket, this method requires a long time to properly apply the pocket.

It must be noted that in some cases, the label is folded in two before application to the fabric sheet, so that the slot is formed after application and sewing of the label. These tags may be stored in a folded or unfolded state. In the latter case, the label needs to be manually folded immediately before being sewn to the pocket.

This process for picking up and positioning the labels suffers from serious drawbacks.

A first drawback is that picking and positioning the label on the web requires a high degree of operator precision. As already mentioned, the operator must from time to time place the tag in the same position with respect to the pocket so that the garment is identical. Obviously, the operator must be skilled and trained to properly place the label between the piece of fabric and the pocket.

A second drawback is that when the labels are not stored in the folded condition, they must be folded manually by the operator and then placed between the piece of fabric and the pocket. Obviously, such folding operations are long, difficult and require a high level of attention and precision.

WO2017194714 discloses a sewing machine comprising a bearing frame on which a sewing head is mounted, a loading fixture, a work surface and a support arm.

US5133271 discloses a workpiece fabric folding device having a clamping mechanism for a label which is sewn to the fabric.

EP1231312 discloses a quick tag insertion device for sewing machines, in particular for positioning sewing machines.

Detailed Description

Referring to fig. 1-8, a folding device according to the present invention is disclosed and is generally indicated by reference character C.

The folding device C comprises a folder 200 for folding and applying the pocket or patch on the piece of fabric. The folding device C comprises a panel D, shown in fig. 1 and 6, to support the pocket or patch.

The folding device C comprises an applicator 100 for picking up the labels E and moving them until they are arranged partially under the pockets or patches.

With reference to fig. 1, 1A, 1B, 2A and 2B, the labelling machine 100 comprises a storage device 2 having a compartment 21 for storing labels E and an outlet 22 for ejecting the labels E from the compartment 21.

More precisely, the storage device 2 extends vertically so that the labels E are stacked one on top of the other. The outlet 22 is in an upper position with respect to the compartment 21.

Each label E stacked in compartment 21 is folded in such a way as to have two edges E1, E2.

The storage device 2 comprises an extraction column 26, arranged in an upper position with respect to said compartment 21, comprising an extraction mouth 26 a; the extraction column 26 further comprises moving means and extraction means (not shown in the figures). It has to be noted that the pick-up means may be different, such as a needle.

The moving means are configured such that the extraction column 26 can be moved from a first position, in which the extraction column 26 is arranged above the compartment 21 with the extraction opening 26a close to the outlet 22, to a second position, in which the extraction column 26 is partly accommodated in the compartment 21 with the extraction opening at a remote position with respect to the outlet 22.

The extraction means are adapted to extract air from within the extraction opening 26a to retain the label E within the extraction opening 26 a.

More precisely, the extraction column 26 is moved by the moving means until said extraction opening 26a comes into contact with the aforementioned label E to be picked up; next, when the extraction column 26 is moved from the second position to the first position, the extraction device is actuated in such a way that the label E is held and lifted by said extraction column 26 (fig. 1A, 1B).

With reference to fig. 1A and 1B, the storage device 2 comprises two metal plates Y having two free edges defining an exit 22 into which a label E is to be inserted.

The storage device 2 further comprises a slide 20 aligned with said exit opening 22 of the storage device, the slide 20 being configured to move a label E located on the extraction opening 26a to the outside of the storage device 2 through the exit opening 22.

As shown in fig. 1A, the slide plate 20 is arranged in the vicinity of the outlet 22, and the extraction opening 26a of the extraction column 26 is arranged in an intermediate position between the slide plate 20 and the outlet 2 when the extraction column 26 is in its second position.

The storage means 2 comprise moving means MM which allow the slide 20 to assume a first position (fig. 1A) in which it is in a remote position with respect to the two metal plates Y, and a second position (fig. 2B) in which the front end of said slide 20 is inserted between said two metal plates Y so as to push the label E from the outlet 22 towards the gripper 1.

Referring to fig. 1B, the storage device 2 further comprises a nozzle 29 disposed adjacent the sled, the nozzle being disposed at a proximal position relative to the sled 20 and the extraction column 26.

The nozzle 29 is constructed in such a way that: when said label is held in front of the outlet 22 by the extraction column 26, air is blown in a direction intercepting the label E, so as to propagate in this way out of the two edges E1, E2 and insert the front end of the slide between said two edges E1, E2, so as to push the label E towards the outlet 22.

With reference to fig. 1 to 8, the labelling machine 100 comprises a gripper 1 adapted to grip the label E moved by a sled 20.

The labelling machine 100 comprises an opening/closing device 3 connected to the clamp 1 so that the clamp 1 can assume an open position and a closed position. The opening/closing device 3 is provided on the support surface P and supports the jig 1. Furthermore, the labelling machine 100 comprises a movement device 4 which moves the gripper 1 between a position close to the storage device 2 and a position far from the storage device 2. More precisely, the moving means 4 move the support surface P, where the opening/closing means 3 of the support gripper 1 are arranged. When the clamp 1 is in a remote position relative to the storage device 2, the clamp 1 is located below the folder 200 and the label E is partially disposed between the piece of fabric and the bag or patch.

Referring to fig. 9 and 10, the clamp 1 comprises two

Referring to fig. 4 and 4A, the linear actuator 30 of the opening/closing device 3 moves the diffuser 31 to the second forward position in order to close the

arms

10a, 10b of the clamp 1. In view of the above, the label E is firmly gripped by the

front portions

15a, 15b of the

arms

10a, 10b of the gripper 1.

Referring to fig. 5 and 5A, the slide 20 is disposed in its first retracted position and the moving device 4 moves the gripper 1 supporting the label E so that the gripper moves away from the storage device 2.

As shown in fig. 6 to 8, the moving device 4 moves the gripper 1 to a distant position with respect to the storage device 2, that is, moves the gripper 1 below the folder 200, and places the label E between the upper surface of the fabric sheet and the side edge of the pocket so that the label E partially protrudes from the side edge of the pocket.

Alternatively, the label may be inserted when the gripper has completed its folding step and moved backwards.

The folder 200 is disposed on the web so as to apply the pocket or patch to the web, while the labeler 100 places the label E on the web beneath the pocket or patch.

The clamp 1 does not move and supports the label E when the pocket or patch is positioned on the fabric sheet.

The opening/closing device 3 then opens the

arms

10a, 10b of the gripper 1 and the labelling machine 100 returns to its idle position (fig. 1).

It has to be noted that the labels E stored in the storage means 2 shown in fig. 1-8 may be pre-folded labels E, i.e. said labels E are provided in a pre-folded state in the compartments 21 of the storage means 2.

Fig. 11 to 20 show a first embodiment of a labelling machine of a folding device C according to the invention, which, in addition to moving the labels E, pre-folds said labels E in an extended state, i.e. not folded, inside the storage means 2.

In the following description, the same or corresponding parts as those described above are identified by the same reference numerals, and detailed description thereof is omitted.

The labelling machine 100 comprises a folding apparatus 5, the folding apparatus 5 comprising two fingers 50 adapted to take the labels E in the extended position out of the outlet 22 of the storage device 2 and to fold the labels E in the stretched condition.

The folding apparatus 5 comprises an opening/closing device (not shown in the figures) connected to the fingers 50 to move said fingers 50 closer/farther. More specifically, the fingers 50 may be in a proximal position, wherein the fingers 50 are in contact to support the label, as shown in fig. 15, and the fingers 50 may be in a distal position, wherein the fingers are spaced apart to allow insertion of the label E between the fingers 50, as shown in fig. 11.

The folding apparatus 5 comprises a rotation device 52 (not shown in the figures) connected to said fingers 50, said rotation device 52 rotating said fingers 50 by 180 ° about a horizontal axis with respect to the central position of the two fingers 50 when said fingers 50 are in the horizontal position.

Advantageously, the folding apparatus 5 comprises translation means (not shown in the figures) to move the finger 50 closer to/further from the outlet 22 of the storage device 2.

The folding apparatus 5 comprises fastening means 53, the fastening means 53 being adapted to support and fasten the tag E when it is folded. Referring to fig. 11 and 12, the gripper 1 picks up the label E and moves the label E out of the storage device 2.

Referring to fig. 13, when the label E passes under the rotating lever of the fastening device 53, the rotating lever rotates in such a manner as to block the label E. The gripper 1 opens to release the label E.

Referring to fig. 14, the finger 50 in the open position moves closer to the tag E and is arranged in such a way that: one finger is above the label E and the other finger is below the label E.

With reference to fig. 15 to 17, the fingers 50 are closed to pick up the labels E and rotated by 180 ° about their rotation axis to fold the labels E.

Referring to fig. 18 to 20, the gripper 1 moves closer to the label E and grips the label E near its folded edge. The rotating lever of the fastening device 53 is lifted and the finger 50 is opened in order to release the label E.

Fig. 21 to 31 show a second embodiment of a labelling machine 100 according to the invention with two illustrated grippers 1. The clamp 1 is identical to the clamp 1 described above.

The jigs 1 are connected to each other and fixed to the support 6 so as to support the jigs. The support 6 is connected with the moving device 4 to move the two clamps 1 simultaneously.

More precisely, the clamps 1 are in adjacent parallel positions.

Referring to fig. 21 to 24, the moving device 4 moves the support 6 in such a manner that the first gripper 1 moves closer to the storage device 2 so as to pick up the first label.

Next, as shown in fig. 25 to 27, the moving device 4 moves the support 6 in such a manner as to move the second gripper 1 closer to the storage device 2 so as to pick up the second label.

Referring to fig. 28-31, the moving device 4 moves the support 6 until the label is partially disposed under an angle formed by the upper edge of the pocket and the side edge of the bag or patch. The holder 1 supports the label until the pocket or patch is positioned by the folder 200 on the piece of fabric to be sewn.

It must be noted that the distance between the two clamps 1 coincides with the distance between the side edges of the folded pocket.

Although not shown in the drawings, the storage means 2 may comprise a roller on which the roll of labels is wound. A breaking line, for example included in a precut line, is provided between two successive labels E. When the gripper 1 pulls the label E, the breaking line breaks, separating the label E from the other labels. Alternatively, the labelling machine 100 may comprise a blade which separates the label E from the other labels E when coming out of the storage means.

Finally, it must be noted that the label may be part of a textile or non-textile material with stiffening or stabilizing properties, in particular for sewing pockets, patches or elastic fabrics, which may be damaged if washed or otherwise handled.

In view of the above, the hardened or stabilized labels can be continuously removed after the treatment, since they have a technical function rather than an aesthetic function, intended not to damage the fabric piece or the seams fixing the patch or pocket to the garment.
