The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0056] The first aspect of this application provides a fabric piece adjusting device capable of adjusting the angle of fabric piece placement. To more clearly illustrate the structure of the fabric piece adjusting device, it will be described below in conjunction with the accompanying drawings. Please refer to... Figure 1 as well as Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of the cut piece adjustment device provided in the embodiments of this application. Figure 2 This is a partial structural diagram of the material placement plate 100 in one embodiment of this application.

[0057] For example, the cut piece adjustment device includes a placement plate 100, a drive assembly, a cover plate 200, and a first air supply component. The placement plate 100 is used to place the cut piece 10, and a limiting member 110 is provided on the placement plate 100. The drive assembly is connected to the cover plate 200 and is used to drive the cover plate 200 to move relative to the placement plate 100. The cover plate 200 is used to limit the range of motion of the cut piece 10 on the placement plate 100 in the direction of gravity. The first air supply component is used to supply air towards the limiting member 110 so that the cut piece 10 moves on the placement plate 100 and abuts against the limiting member 110.

[0058] The aforementioned cut piece adjustment device, by setting a limiting member 110 on the material placement plate 100 and controlling the cover plate 200 to move relative to the material placement plate 100 through the drive assembly, effectively limits the range of motion of the cut piece 10 in the direction of gravity. Furthermore, by supplying air to the limiting member 110 through the first air supply component, the cut piece 10 can stably contact the limiting member 110 without easily causing wrinkles, and can automatically adjust the cut piece 10 to a specific position even when there is an unknown deviation in its initial position.

[0059] Furthermore, the above-mentioned cutting piece adjustment device is particularly suitable for adjusting the posture of thin cutting pieces. By adjusting the air supply force of the first air supply component, the cutting piece 10 can be adjusted in posture through continuous small changes, effectively preventing the cutting piece 10 from rebounding or folding due to strong pushing when it comes into contact with the limiting member 110.

[0060] Furthermore, under the action of the cover plate 200, the influence of the direction of gravity can be ignored, so that the first air supply component does not need to be strictly pointed to the specific position of the limiting member 110, allowing for some deviation in the direction of gravity, thereby improving the adaptability of the cut piece adjustment device.

[0061] In some embodiments, the limiting member 110 includes a protrusion structure protruding from the material plate 100.

[0062] Alternatively, the limiting member 110 may be a single, continuously extending protruding structure.

[0063] Optionally, there are multiple protrusions, which are arranged at intervals along a straight line.

[0064] In some embodiments, the drive assembly includes a mounting member 310, a first drive cylinder 330, and a connector. The mounting member 310 is used to connect to the frame, the connector is used to connect to the cover plate 200, and the first drive cylinder 330 is connected to both the mounting member 310 and the connector, and is used to drive the cover plate 200 to move.

[0065] In some embodiments, the cut piece adjusting device further includes a first hinge seat 210 and a hinge assembly 220. The first hinge seat 210 is installed on the side of the cover plate 200 away from the material placement plate 100, and the connecting member is connected to the cover plate 200 through the first hinge seat 210; the hinge assembly 220 connects the cover plate 200 and the material placement plate 100 respectively.

[0066] In some embodiments, the connector is a rod end spherical bearing.

[0067] In some embodiments, the mounting element 310 is connected to the first drive cylinder 330 via a second hinge seat.

[0068] With the above settings, under the driving action of the first drive cylinder 330, the cover plate 200 can swing about the hinge assembly 220 as the axis.

[0069] In some embodiments, the cut piece adjusting device further includes at least one set of fixing mechanisms and a second air supply component. The fixing mechanisms are movable relative to the placement plate 100 to press or release the cut piece 10 on the placement plate 100, and the second air supply component supplies air towards the side opposite to the limiting member 110 to spread the cut piece 10 fixed by the fixing mechanisms. Reverse air supply further ensures that the cut piece 10 is wrinkle-free. Optionally, the air supply directions of the second air supply component and the first air supply component have opposite projection directions on the placement plate 100. Further, the air supply directions of the second air supply component and the first air supply component are symmetrical.

[0070] In some embodiments, the fixing mechanism includes a second drive cylinder 420 and a first pressing member 410. The second drive cylinder 420 is installed on the side of the cover plate 200 away from the material placement plate 100, and is used to drive the first pressing member 410 to move relative to the material placement plate 100. A positioning hole 230 is provided on the cover plate 200, through which the first pressing member 410 can pass to press the cut piece 10 on the material placement plate 100. By adding a positioning hole 230 to the cover plate 200 and cooperating with the first pressing member 410 to fix the cut piece 10, the reverse air supply of the second air supply component can be avoided, which would cause the cut piece 10 to shift.

[0071] In some embodiments, the first pressing member 410 includes at least two pressing contacts that can pass through the positioning hole 230 under the action of the second driving cylinder 420 to press the cut piece 10 on the material plate 100.

[0072] In some embodiments, the cut piece adjusting device includes two sets of fixing mechanisms. The first pressing members 410 of the two sets of fixing mechanisms are arranged horizontally and are used to cooperate in pressing the two sides of the cut piece 10.

[0073] In some embodiments, the material plate 100 has at least one first air passage 120, and the first air supply component supplies air through the first air passage 120.

[0074] In some embodiments, the material placement plate 100 has 5 to 10 first air channels 120, which are arranged linearly and in the same direction as the extension direction of the limiting member 110. By controlling the air supply through the multiple first air channels 120, the air supply force of each first air channel 120 can be reduced while ensuring the effective movement of the cut piece 10, thereby avoiding unexpected deformation of the cut piece 10 caused by providing a large air supply force in a certain direction.

[0075] In some embodiments, the opening direction of the first air passage 120 is inclined toward the limiting member 110. Furthermore, the vertical projection of the first air passage 120 on the material plate 100 is perpendicular to the extending direction of the limiting member 110.

[0076] In some embodiments, the opening direction of the first air passage 120 is tilted at an angle of 10° to 60° relative to the plane of the material plate 100.

[0077] In some embodiments, the material plate 100 is provided with at least one second air passage 130, and the second air supply component supplies air through the second air passage 130.

[0078] In some embodiments, the material plate 100 has 5 to 10 second air passages 130, which are arranged linearly and in the same direction as the extension direction of the limiting member 110.

[0079] In some embodiments, the opening direction of the second air passage 130 is opposite to that of the limiting member 110. Optionally, the opening direction of the second air passage 130 and the first air passage 120 are opposite in direction to the vertical projection on the material plate 100. Further, the opening directions of the second air passage 130 and the first air passage 120 are symmetrical.

[0080] In some embodiments, the opening direction of the second air passage 130 is tilted at an angle of 10° to 60° relative to the plane of the material plate 100.

[0081] In a second aspect, this application provides a method for positioning a cut piece 10.

[0082] For example, the cutting piece 10 positioning method uses the above-mentioned cutting piece adjustment device and includes the following steps:

[0083] S1. Place the cut piece 10 on the material placement plate 100 and control the cover plate 200 to be close to the material placement plate 100.

[0084] S2. Air is supplied through the first air supply component, causing the cut piece 10 to come into contact with the limiting member 110.

[0085] In some embodiments, the cover plate 200 is controlled to be close to the material placement plate 100, such that the maximum vertical distance between the cover plate 200 and the material placement plate 100 is 0.5cm to 2.5cm. The distance between the cover plate 200 and the material placement plate 100 should not be too small, otherwise the movement of the cut piece 10 will be hindered, and a large air force will be required to blow it; the distance between the cover plate 200 and the material placement plate 100 should not be too large, otherwise unexpected movement may occur due to different positions of the cut piece 10, or even reverse folding.

[0086] In some embodiments, after the cut piece 10 is fed to the limiting member 110, the following steps are also included:

[0087] S3. The cut piece 10 is pressed by the fixing mechanism and air is supplied by the second air supply component to spread the cut piece 10.

[0088] A third aspect of this application provides an automatic feeding device for cut pieces 10, capable of automatically separating, flattening, and positioning them. To more clearly illustrate the structure of the cut piece adjusting device, the automatic feeding device for cut pieces 10 will be described below in conjunction with the accompanying drawings. Please refer to... Figures 3-6 As shown, where Figure 3 This is a schematic diagram of the structure of the feeding platform 510 in one embodiment of this application. Figure 4 This is a schematic diagram of the lifting component in one embodiment of this application. Figure 5 This is a schematic diagram of the material distribution mechanism in one embodiment of this application. Figure 6 This is a schematic diagram of the feeding mechanism in one embodiment of this application.

[0089] For example, the automatic feeding device for cut pieces 10 includes a feeding table 510, a sorting mechanism, a feeding mechanism, and the aforementioned cut piece adjustment device. The sorting mechanism includes a lifting assembly, a first synchronization frame 532, and at least two clamping components. The lifting assembly and the first synchronization frame 532 are mounted on a frame. The clamping components are movably connected to the first synchronization frame 532. The lifting assembly lifts the cut pieces 10 on the feeding table 510, and the clamping components unfold and grip the lifted cut pieces 10. The first synchronization frame 532 can transport the gripped cut pieces 10 to a first waiting area. The feeding mechanism includes a multi-directional moving assembly and a second pressing component. The second pressing component is mounted on the multi-directional moving assembly and can move in multiple directions. The second pressing component transfers the cut pieces 10 from the first waiting area to the placement plate 100 of the cut piece adjustment device. The cut piece adjustment device is used to adjust the orientation of the cut pieces 10.

[0090] In some embodiments, the automatic feeding device for cut pieces 10 further includes a first driver connected to the feeding table 510, which is used to drive the feeding table 510 to rise and fall.

[0091] In some embodiments, the feed table 510 is provided with a cut piece detector 511, which is used to detect whether there is a cut piece 10 in a specific area of ​​the feed table 510.

[0092] In some embodiments, the lifting assembly includes a pin 521 and a second driver 522, the pin 521 being perpendicular to the plane of the shelf, and the second driver 522 being capable of driving the pin 521 to rise and fall, so that the pin 521 engages and lifts the first layer of multiple stacked cut pieces 10 on the shelf.

[0093] In some embodiments, the lifting assembly further includes a position detector, which is used to trigger the gripping action of the lifting assembly. Specifically, the first driver drives the feed table 510 to rise, and when the cut piece 10 lifts the pin 521 to a certain height, it triggers the position detector, which in turn triggers the gripping action of the lifting assembly to lift the uppermost cut piece 10.

[0094] In some embodiments, the lifting assembly also includes an air blowing assembly, which can assist in the separation of the cut piece 10 by blowing air after the pin 521 pierces the cut piece 10.

[0095] In some embodiments, the gripping component includes a gripping arm 531, which is movably mounted on a first synchronization frame 532 and is capable of moving along the first synchronization frame 532.

[0096] In some embodiments, the clamping arm 531 includes an upper clamping plate and a lower clamping plate, the upper clamping plate being able to move up and down relative to the lower clamping plate to clamp or release the cut piece 10.

[0097] In some embodiments, the frame is also provided with two sets of horizontally aligned first guide rails 533, and the two ends of the first synchronization frame 532 are movably connected to the two sets of first guide rails 533, and the first synchronization frame 532 can move along the first guide rails 533.

[0098] The multi-directional moving assembly includes a second synchronous frame 543, a lifting component 542, and two sets of horizontally aligned second guide rails 544. The lifting component 542 is connected to the second pressing component and can drive the second pressing component to move up and down to press the cut piece 10. The lifting component 542 is movably mounted on the second synchronous frame 543 and can move along the second synchronous frame 543. Both ends of the second synchronous frame 543 are movably connected to the two sets of second guide rails 544, and the second synchronous frame 543 can move along the second guide rails 544.

[0099] In some embodiments, the multi-directional movement component is used to move the cut piece 10, which has been adjusted by the cut piece adjustment device, to a subsequent process.

[0100] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
