[0025] Reference Figure 1-4 The automatic cloth picking and placing device of this embodiment includes a bracket 2, a cloth sticking mechanism arranged on the bracket 2, a stripping sheet 3 slidably arranged on the bracket 2, a return mechanism for providing a downward movement trend of the stripping sheet 3, a limiting mechanism for limiting the up and down movement of the stripping sheet 3, an updating mechanism for driving the cloth sticking mechanism to update, and a telescopic mechanism for fixing the stripping sheet 3 at the highest point of its movement. Among them, the stripping sheet 3 includes a pressing sheet 31 and a connecting sheet 32 ​​arranged perpendicularly to each other, and a through hole 311 is opened on the pressing sheet 31 for part of the cloth sticking mechanism to move through, and the connecting sheet 32 ​​is connected to the sliding plate 5. The connecting sheet 32 ​​is fixedly connected to the limiting mechanism, and the upward and downward movement of the limiting mechanism drives the stripping sheet 3 to move up and down.

[0026] The following is a description of the structures of each of the above institutions:

[0027] The limiting mechanism includes a sliding plate 5 slidably arranged on the bracket 2, a sliding groove 51 provided on the sliding plate 5, and a guide block 4 fixed on the bracket 2, wherein the guide block 4 is located in the sliding groove 51. The connecting piece 32 of the stripping sheet 3 is fixedly connected to the sliding plate 5. The position of the guide block 4 is fixed, and the sliding groove 51 is slidably moved up and down by the cooperation between the guide block 4 and the sliding groove 51.

[0028] The return mechanism includes a fixed plate 6 fixed on the guide block 4 and an elastic member 7 connecting the fixed plate 6 and the sliding plate 5. The fixed plate 6 is provided with a lower fixing hole 61, the sliding plate 5 is provided with an upper fixing hole 52, the lower end of the elastic member 7 acts on the lower fixing hole 61, and the upper end of the elastic member 7 acts on the upper fixing hole 52. The elastic member 7 in this embodiment is a spring, and the upper and lower ends of the spring have hooks for hooking the upper fixing hole 52 and the lower fixing hole 61 respectively.

[0029] Under normal circumstances, the elastic member 7 is in a natural state. When the cloth is being picked up, the stripping piece 3 moves up, driving the sliding plate 5 to move up, and the elastic member 7 is stretched. After the automatic cloth picking and placing device moves to the specified position, the elastic member 7 needs to return to its original position, driving the sliding plate 5 to move downward, and then the stripping piece 3 moves downward, thereby removing the cloth from the cloth picking mechanism.

[0030] The bracket 2 in this embodiment includes a side ear 201, and the fabric sticking mechanism includes an upper tape seat 81 arranged on the upper part of the bracket 2 through an upper tape wheel shaft 811, a lower tape seat 82 arranged on the side ear 201 through a lower tape wheel shaft 821, a pressure wheel 10 arranged at the lower part of the bracket 2 through a pressure wheel shaft 101, and a guide wheel 11 for guiding the movement of the tape 12, the guide wheel 11 is arranged on the bracket 2 through a guide wheel shaft 111, and bearings 22 are arranged between each wheel and each wheel shaft, a rubber ring 91 is arranged on the upper tape seat 81, and an inner ring 92 is arranged on the lower tape seat 82, and the tape 12 on the rubber ring 91 is led out by the rubber ring 91 and wound around the inner ring 92 after passing through the pressure wheel 10. The pressure wheel 10 is located above the stripping sheet 3 to match the through hole 311. It can move downward from the through hole 311 so that the tape 12 can stick to the cloth from the through hole 311. Therefore, the horizontal height of the pressure wheel 10 is the lowest relative to the horizontal heights of the upper tape seat 81, the lower tape seat 82 and the guide wheel 11. The rubber ring 91 on the upper tape seat 81 is the tape 12 before sticking to the cloth. After passing through the guide wheel 11 and the pressure wheel 10, it is wound on the inner ring 92, that is, the waste tape after sticking to the cloth is wound on the inner ring 92. In this embodiment, a tape limiting plate 20 is also provided between the lower tape seat 82 and the bracket to allow the waste tape to be more neatly wound on the inner ring 92.

[0031] The updating mechanism and the lower tape holder 82 are respectively located on both sides of the bracket 2. The updating mechanism includes a ratchet 13 coaxially connected to the lower tape holder 82, an active claw 141 rotatably connected to the sliding plate 5, and a separation component for controlling the active claw 141 to separate from the ratchet 13. The active claw 141 is provided with a first elastic component 142 for providing a tendency for the active claw 141 to engage with the ratchet 13. The active claw 141 is provided on the sliding plate 5. When the active claw 141 engages with the ratchet 13, the ratchet 13 is driven to rotate by the upward movement of the sliding plate 5, thereby driving the lower tape holder 82 to rotate, thereby realizing the updating of the tape 12. When the separation component is activated, the active claw 141 is separated from the ratchet 13, and the movement of the sliding plate 5 will not affect the rotation of the ratchet 13. By providing the separation component, the updating cycle of the tape 12 can be controlled.

[0032] The separation assembly includes a stopper wheel 16 disposed on the active claw 141, a cylinder 171 disposed on the sliding plate 5, and a driving head 172 disposed at the end of the piston rod of the cylinder 171. The driving head 172 is used to drive the stopper wheel 16 to rotate the active claw 141. The cylinder 171 is fixed to the sliding plate 5 through a cylinder seat 173. The movement of the driving head 172 is controlled by the cylinder 171, and the rotation of the active claw 141 is achieved through the matching of the driving head 172 and the stopper wheel 16, and the engagement and separation of the active claw 141 and the ratchet 13 are controlled. That is, the first elastic component 142 is used to achieve the engagement of the active claw 141 with the ratchet 13, and the separation assembly is used to achieve the separation of the active claw 141 from the ratchet 13. The cylinder 171 in the separation assembly is selected as a needle-type cylinder 171. In this embodiment, the driving head 172 is configured to be in a shape similar to a bullet head so that the driving head 172 can contact the blocking wheel 16 smoothly without causing collisions and other problems; and the blocking wheel 16 in this embodiment is arranged on the upper side of the connection point between the active claw 141 and the sliding plate 5.

[0033] The bracket 2 is fixed with a stop pawl 181 for preventing the ratchet 13 from rotating in the reverse direction and a second elastic component 182 for providing a tendency for the stop pawl 181 to engage with the ratchet 13. The second elastic component 182 is used to ensure that the stop pawl 181 engages with the ratchet 13 to prevent the ratchet 13 from rotating in the reverse direction. In this embodiment, the first elastic component 142 and the second elastic component 182 are torsion springs.

[0034] When the bottom end of the guide block 4 contacts the bottom end of the sliding groove 51, the sliding plate 5 and the stripping sheet 3 are both located at the highest point of their respective movements. The telescopic mechanism and the limiting mechanism are respectively located on both sides of the bracket 2. The telescopic mechanism includes a telescopic cylinder 191 and a telescopic head 192 located at the end of the telescopic cylinder 191. When the bracket 2 corresponds to the highest point of the movement of the sliding plate 5, the top of the sliding groove 51 is provided with a blocking hole 202 for the telescopic head 192 to pass through. The telescopic cylinder 191 is fixed to the bracket 2 through a cylinder support block 193. When the sliding plate 5 moves to the highest point, the guide block 4 is located at the lowest end of the sliding groove 51, and there is a certain distance between the top of the guide block 4 and the top of the sliding groove 51. The blocking hole 202 is opened in the space corresponding to the distance. The telescopic cylinder 191 drives the telescopic head 192 to extend from the blocking hole 202 into the sliding groove 51. The telescopic head 192 abuts against the upper end of the sliding groove 51 to prevent the sliding plate 5 from moving downward, that is, to fix the stripping sheet 3 at the highest point of its movement. The telescopic cylinder 191 in this embodiment is selected as a needle-type cylinder 191.

[0035] In this embodiment, a sensor 231 is also installed on the bracket 2, and a sensing plate 232 cooperating with the sensor 231 is installed on the upper part of the sliding plate 5. When the sliding plate 5 moves upward, when the sensor 231 senses the sensing plate 232, the sliding plate 5 stops moving, and then the telescopic mechanism is activated to lock the sliding plate 5.

[0036] This embodiment also provides a sewing device including the above-mentioned automatic cloth picking and placing device, which can realize automatic cloth picking and placing in the process of sewing products. In order to realize the movement of the automatic cloth picking and placing device, a mounting plate 1 can be fixed on the bracket 2, and the mounting plate 1 is connected to a moving mechanism such as a horizontal moving cylinder 171, etc., to realize the operation of sticking cloth at a fixed place, and driven by the moving mechanism to remove the cloth when it reaches another fixed place. Other components of the sewing device can be conventionally selected according to common knowledge in the field.

[0037] The working process and working principle of the automatic cloth taking and placing device in this embodiment are briefly described below:

[0038] The automatic cloth picking and placing device is installed on the moving mechanism through the mounting plate 1, and the moving mechanism drives the automatic cloth picking and placing device to move. After the automatic cloth picking and placing device moves to the fixed location for picking up the material, the servo-controlled up and down moving workbench drives the cloth pile and the cloth to move upward, and the cloth first hits the stripping sheet 3, and pushes the stripping sheet 3 and the sliding plate 5 and the components fixed on the sliding plate 5 such as the sensing plate 232, the active claw 141, and the cylinder 171 to move upward, at which time, the elastic member 7 is stretched. In order to make the cloth more firmly connected to the tape 12 of the pressing wheel 10, the cloth pile will press the pressing wheel 10 and continue to move upward for a distance, so that part of the pressing wheel 10 and the tape 12 under the pressing wheel 10 pass through the through hole 311 to stick to the cloth, until the sensor 231 senses the sensing plate 232, and the stripping sheet 3 and the sliding plate 5 no longer move upward.

[0039] When the sensor 231 senses the sensing plate 232, the telescopic cylinder 191 is activated, pushing the telescopic head 192 through the blocking hole 202 to the slide groove of the sliding plate 5, and the telescopic head 192 abuts against the upper end of the slide groove 51, thereby locking the sliding plate 5 to prevent the sliding plate 5 and the stripping sheet 3 from moving downward. After that, the workbench drives the cloth pile to move downward, the pressing wheel 10 is separated from the cloth pile, and the automatic cloth picking and placing device is driven by the moving mechanism to move to another fixed location, and the telescopic cylinder 191 retracts the telescopic head 192, the sliding plate 5 is reset under the action of the elastic member 7, and drives the stripping sheet 3 to move downward to take off the cloth, completing a picking and placing action.

[0040] When the driving head 172 of the needle cylinder 171 is not extended, the driving head 172 is not in contact with the stopper wheel 16, and the active claw 141 is engaged with the ratchet 13 under the drive of the first elastic component 142. During the upward movement of the stripping sheet 3 and the sliding plate 5, the active claw 141 rotates the ratchet 13, thereby rotating the lower tape holder 82 coaxially connected to the ratchet 13, thereby realizing the renewal of the outer tape 12 of the pressing wheel 10.

[0041] When the needle cylinder 171 is in motion, the piston rod of the needle cylinder 171 drives the driving head 172 at its end to move upward, and the driving head 172 touches the stopper wheel 16, and drives the stopper wheel 16 to drive the active claw 141 to rotate, so that the active claw 141 is separated from the ratchet wheel 13. At this time, when the sliding plate 5 moves upward, it will not drive the ratchet wheel 13 to rotate, will not drive the lower tape holder 82 to rotate, and will not update the tape 12 on the pressing wheel 10. When the needle cylinder 171 is retracted, the active claw 141 is reset under the action of the first elastic component 142. At this time, when the sliding plate 5 moves upward, the active claw 141 will force the ratchet wheel 13 to rotate. Through such a setting, the update cycle of the tape 12 outside the pressing wheel 10 can be controlled.

[0042] When the needle cylinder 171 is extended, the active claw 141 is disengaged from the ratchet 13, and the ratchet 13 will not rotate when moving upward; when the needle cylinder 171 is retracted, the active claw 141 is reset under the action of the torsion spring, and the active claw 141 will force the ratchet 13 to rotate when moving upward, so that the renewal cycle of the outer tape 12 of the pressure wheel 10 can be controlled, and the tape 12 can be renewed after taking and placing the cloth many times.

[0043] The tape 12 on the rubber ring 91 passes through the guide wheel 11 and the pressure wheel 10 and is wound around the inner ring 92 of the tape 12; after the tape 12 is used up, the inner ring 92 wound with the waste tape and located at the lower tape holder 82 is replaced with the remaining inner ring of the rubber ring 91;

[0044] In order to better grasp the cloth, multiple cloth automatic picking and placing devices can be set according to the size of the cloth, and one or more sensors 231 can be installed. And the distance of the pressing wheel 10 protruding from the stripping sheet 3 can be adjusted according to the state of the cloth.

[0045] The automatic cloth picking and placing device of the present invention has a reasonable structural design and a compact structure. By setting a through hole, when the stripping piece moves upward, part of the cloth sticking mechanism passes through the through hole downward to stick the cloth. After the cloth is stuck, the position of the stripping piece remains unchanged. After the cloth picking and placing device moves to a specified position, the recovery mechanism is activated to press the stripping piece downward, so that the cloth is taken off from under the cloth sticking mechanism, thereby realizing automatic cloth picking and placing.

[0046] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
