Specifically, based on the existing garment sewing mode, the overlapping area edges of the front cut piece positioned in front of the chest of the human body and the rear cut piece positioned behind the human body are required to be sewn, namely, the 'side seams' of the garment are required to be sewn, and after the side seams are completed, the hem, the cuffs, the neckline and the like of the garment are required to be sewn.

The garment with the side seams needs to be turned inside out and then subjected to the next process. In the related art, the internal and external turnups of the clothing with the side seams are needed to be completed by manual operation and then are sleeved on a lower hem machine. Therefore, the sewing line 200 must be configured with a corresponding operator on duty to turn over and set the garment, which is too low in productivity.

In view of the foregoing, embodiments of the present invention provide a turn-over device 100 for turning over the inside and outside surfaces of a sewn article.

The sewing product comprises a first cloth layer and a second cloth layer which are stacked, and two opposite sides of the first cloth layer and the second cloth layer pass through side seams, so that the edge of the first cloth layer of the sewing product is connected with the edge of the second cloth layer, and a first opening is formed at the first end of the sewing product along the first direction.

In one embodiment, the turn-up device 100 is used to turn up and around a hem machine for hem stitching of a garment having completed a hem seam. The side seam device 110 is used for side seam of the garment, the turn-over device 100 is used for turning over the garment, and the turned-over garment is sleeved on the lower hem sewing device 120 in the next process, so that the turn-over device 100 can automatically finish the turn-over and sleeving process of the garment before the lower hem processing, and can replace manual operation to realize automation.

The description is made herein with the positive and negative directions of the X axis as the first direction, the positive and negative directions of the Z axis as the second direction, and the positive and negative directions of the Y axis as the third direction in fig. 1.

Referring to fig. 1-3, in some embodiments, the opening mechanism 10 includes a gripping mechanism 18 and a securing mechanism 20. The clamping mechanism 18 is used for fixing and driving the first cloth layer to move so as to enlarge the first opening. The fixing mechanism 20 is used for fixing the second cloth layer under the condition that the first opening is enlarged, and is used for driving the first end to act after the sewn product is turned over so that the first end faces the sleeving mechanism 14.

In this way, the clamping mechanism 18 fixes the first cloth layer, the fixing mechanism 20 fixes the second cloth layer, and the clamping mechanism 18 or the fixing mechanism 20 moves to drive the cloth layer to move, so that the first opening can be enlarged.

Specifically, the opening mechanism 10 includes a gripping mechanism 18 and a fixing mechanism 20. The clamping mechanism 18 is used for fixing or driving a part of the first cloth layer to move, and the fixing mechanism 20 is used for fixing and driving a part of the second cloth layer to move, so that a first opening formed by connecting edges of the first cloth layer and the second cloth layer can be enlarged.

Referring to fig. 2, in some embodiments, the gripping mechanism 18 includes a second support 22, a first lifting assembly 24, and a gripping assembly 26, the second support 22 is disposed on the first support 16 by the first lifting assembly 24, the gripping assembly 26 is disposed on the second support 22, and the first lifting assembly 24 is used to drive the second support 22 to move along the first direction.

In this way, the clamping assembly 26 is disposed on the second support 22, and the first lifting assembly 24 can drive the second support 22 and the clamping assembly 26 to move on the first support 16, so that the clamping mechanism 18 can drive the first cloth layer to move to enlarge the first opening.

Specifically, after the clamping assembly 26 fixes the first cloth layer, the first lifting assembly 24 drives the second support 22 and the clamping assembly 26 to move along a direction away from the second cloth layer, so that the first opening is enlarged.

In the illustrated embodiment, the first lifting assembly 24 is configured to move the second support 22 and the clamping assembly 26 along the second direction, so that the clamping assembly 26 may contact and fix the first fabric layer and move the first fabric layer away from the second fabric layer, thereby enlarging the first opening.

Referring to fig. 2, in some embodiments, the clamping assembly 26 includes a needle chuck 27 and a first jaw assembly 28, the needle chuck 27 being configured to separate the first cloth layer from the second cloth layer, and the first jaw assembly 28 being configured to secure the first cloth layer.

Thus, the needle sucker 27 can separate the stacked first cloth layer from the second cloth layer, and the first cloth layer can be fixed by grabbing the first cloth layer by the first clamping jaw assembly 28.

Specifically, the sewn product is transported to the turn-over device 100 after the previous process, the first lifting assembly 24 drives the clamping assembly 26 to descend along the second direction through the second support 22, the clamping assembly moves to the needle type sucker 27 to contact the first fabric layer of the sewn product, the needle type sucker 27 controls the needle to extend out to penetrate the first fabric layer, the first lifting assembly 24 drives the clamping assembly 26 to ascend along the second direction, and the needle type sucker 27 drives the first fabric layer to ascend and stop after a certain distance is reached. At this time, the first clamping jaw assembly 28 is controlled to act to fix the first cloth layer.

It should be noted that the needle type suction cup 27 drives the first cloth layer to rise a certain distance, so that the first opening becomes larger. The first jaw assembly 28 also requires a height when securing the first layer of material to avoid interference with other components on the turn-up device 100. Meanwhile, the height of the clamping assembly 26 for driving the first cloth layer to rise needs to be proper, so that the clamping assembly 26 is prevented from driving the first cloth layer to rise too far, and the second cloth layer is driven by the edge connected with the first cloth layer to rise simultaneously with the first cloth layer, so that the subsequent fixing mechanism 20 cannot fix the second cloth layer.

The specific value of the distance that the needle suction cup 27 drives the first fabric layer to rise is set according to the dimensions and the assembly relation of the components of the turn-over device 100 and the specifications of the sewn product, which is not limited herein.

The first cloth layer is extracted by the way that the needle type sucking disc 27 penetrates the cloth, and the degree of penetrating the cloth can be controlled by adjusting the extending distance of the needle, so that the needle type sucking disc 27 can be prevented from penetrating the first cloth layer and the second cloth layer at the same time.

In one embodiment, the gripping assembly 26 includes two or more needle suction cups 27 that allow the first layer of material to rise in synchronization with the needle suction cups 27 after the needle suction cups 27 pierce the first layer of material. The two or more needle-type suction cups 27 fix the first cloth layer together, so that the first cloth layer can be effectively prevented from being separated from the needle-type suction cups 27.

Referring to fig. 2, in one embodiment, the first jaw assembly 28 includes an upper mount 28a and a lower clamp 28b, the lower clamp 28b being rotatably coupled to the upper mount 28a. The upper mount 28a is movable up and down in a first direction, and the lower clamp 28b is rotatable about a fixed point to move closer to or farther from the upper mount 28a. When the lower-layer clamps 28b are close to the upper-layer clamps 28a around the fixing points and the upper-layer clamps 28a are moved downward, i.e., the upper-layer clamps 28a and the lower-layer clamps 28b are close to each other, the cloth can be clamped between the upper-layer clamps 28a and the lower-layer clamps 28b, and when the lower-layer clamps 28b are far from the upper-layer clamps 28a around the fixing points and the upper-layer clamps 28a are moved upward, i.e., the upper-layer clamps 28a and the lower-layer clamps 28b are far from each other, the cloth is loosened.

Referring to fig. 3-5, in some embodiments, the securing mechanism 20 includes a support plate 30, the support plate 30 is mounted to the first support 16, the support plate 30 is used for placing the sewn product, and the turn-over device 100 includes a mop assembly 31, the mop assembly 31 is mounted to the first support 16, and the mop assembly 31 is used for paving the sewn product on the support plate 30.

Specifically, the support plate 30 is used for receiving the sewn product transferred to the turn-up device 100 after the previous process. The mop assembly 31 comprises a first directional drive 31a, a second directional drive 31b and a mop plate assembly. The first direction driving member 31a and the second direction driving member 31b are used for driving the mop plate assembly to move in the first direction and the second direction, the mop plate assembly comprises a pressing plate 31c and a blowing pipe 31d, the pressing plate 31c is fixedly installed with the first direction driving member 31a, the blowing pipe 31d is installed on the pressing plate 31c, and the blowing pipe 31d blows air in the first direction. When the sewn product is conveyed to the position of the supporting plate 30, the first direction driving piece 31a and the second direction driving piece 31b drive the mop plate assembly to move above the sewn product to press the sewn product, then the air blowing pipe 31d supplies air along the first blowing direction to trim and flatten the sewn product, wrinkles on the sewn product are removed, and the first end of the sewn product is flattened on the supporting plate 30 so that the follow-up clamping mechanism 18 and the fixing mechanism 20 can work.

The cloth mop assembly 31 is used for finishing and paving the sewed products conveyed to the supporting plate 30, so that the phenomenon that the clamping mechanism 18 or the fixing mechanism 20 cannot contact the sewed products due to wrinkles, folding angles and the like when the sewed products are conveyed to the supporting plate 30, and the turnover failure is caused can be prevented, and the operation accuracy of the turnover device 100 is improved.

In one embodiment, the support plate 30 further includes a needle-type suction cup 27, and the needle-type suction cup 27 can extend from below the second cloth layer to penetrate the second cloth layer when extended, so that the second cloth layer moves along with the first cloth layer when the clamping mechanism 18 drives the first cloth layer to move upwards.

When the second jaw assemblies 32 are in the initial position, the two second jaw assemblies 32 are in the middle position of the guide rail, and the opening of the second jaw assemblies 32 faces the positive direction of the second direction. In operation, the third direction driving member drives the second jaw assembly 32 to move to the positions corresponding to the second grooves 30b respectively along the third direction, at this time, the second jaw assembly 32 is located at the second groove 30b, the second jaw assembly 32 rotates to adjust the opening of the jaw to be in the negative direction towards the first direction, at this time, the supporting plate 30 and the second cloth layer are clamped by the second jaw assembly 32, at this time, the second jaw assembly 32 moves to the first groove 30a along the third direction, moves to align with the first groove 30a, and the two second jaw assemblies 32 clamp the second cloth layer at the two first grooves 30a respectively. Thus, the support plate 30 can support the sewn product, and the first groove 30a and the second groove 30b can avoid interference of the support plate 30 when the second clamping jaw assembly 32 turns.

The second cloth layer is clamped at the position of the second groove 30b and then moved to the position of the first groove 30a, so that the phenomenon that the second cloth layer is wrinkled or cannot be clamped completely due to the fact that the second cloth layer is touched when the second cloth layer is clamped at the position of the second groove 30a can be avoided.

Referring to fig. 4, in one embodiment, the second jaw assembly 32 includes an upper jaw 32a and a lower jaw 32b, the upper jaw 32a being movably connected to the lower jaw 32b such that a cloth can be clamped between the upper jaw 32a and the lower jaw 32b when the upper jaw 32a is adjacent to the lower jaw 32b, and released when the upper jaw 32a is moved in a direction away from the lower jaw 32 b. Further, the portion of the upper layer clamping jaw 32a and/or the lower layer clamping jaw 32b, which is in contact with the cloth, further comprises a flexible clamping block 32c, and the flexible clamping block 32c can enable the clamping jaw assembly to clamp the cloth more firmly, and meanwhile has a certain protection effect on the clamped cloth.
