[0033] The present application provides an automatic feeding device for cutting pieces, which can improve the efficiency of cutting piece feeding and avoid problems such as wrinkles or adhesion of the cutting pieces. In order to more clearly illustrate the structure of the automatic feeding device for cutting pieces, the automatic feeding device for cutting pieces will be introduced below with reference to the accompanying drawings.

[0034] For example, see Figure 1 As shown, one embodiment of the present application relates to an automatic cutting piece loading device 10. The automatic cutting piece loading device 10 includes a frame 100, a feeding mechanism 200, a material separation mechanism, and a correction mechanism 400. The material separation mechanism has a first working area for separating and unfolding the cutting pieces 20, and the correction mechanism 400 has a second working area for adjusting the posture of the cutting pieces 20.

[0035] The feeding mechanism 200 includes a movable platform for carrying the cut pieces 20 , and the storage table 210 can move the cut pieces 20 on its surface to the first working area of ​​the dividing mechanism so as to further divide the cut pieces 20 .

[0036] The material separation mechanism includes a lifting assembly, a synchronous frame 320, and at least two gripping components. The lifting assembly is connected to the frame 100 and is capable of lifting the topmost piece 20 on the storage platform 210 in the first working area to separate multiple stacked pieces 20 one by one. The gripping assembly is movably mounted on the synchronous frame 320. The gripping components are capable of horizontally moving on the synchronous frame 320 to accommodate gripping of pieces 20 of varying widths, maintaining the gripped pieces 20 in an extended position. The synchronous frame 320 is movably connected to the frame 100 and is capable of moving the gripping components adjacent to the piece 20 lifted by the lifting assembly so that the gripping components can grip the piece 20. Furthermore, the synchronous frame 320 can transport the gripped piece 20 to the second working area of ​​the straightening mechanism 400 for further straightening.

[0037] The correction mechanism 400 includes an image acquisition device 410 and an adjustment platform 420. The image acquisition device 410 analyzes the orientation of the cut piece 20 on the adjustment platform 420. The adjustment platform 420 rotates to adjust the orientation of the cut piece 20 in the second working area, ensuring that the cut piece 20 maintains a predetermined orientation for subsequent processing steps.

[0038] See also Figure 2 , Figure 2 The figure is a schematic diagram of the structure of a feeding mechanism in one embodiment of the present application. In some embodiments, the feeding mechanism 200 includes a storage platform 210, a lifting guide 221, and a first actuator 222. The storage platform 210 is movably mounted on the frame 100, and the lifting guide 221 is disposed below the storage platform 210. The first actuator 222 is capable of driving the lifting guide 221 up and down, thereby raising and lowering the storage platform 210, thereby transferring the cut pieces 20 from the feeding position to the material distribution mechanism.

[0039] In some embodiments, the lifting guide 221 is a screw. The first driver 222 can drive the screw to rotate, thereby achieving the lifting movement of the screw. The screw can be a ball screw or a trapezoidal screw.

[0040] In some embodiments, a plurality of support rods 230 are provided below the storage platform 210. The support rods 230 can rise and fall synchronously with the storage platform 210 and support the storage platform 210.

[0041] In some embodiments, four support rods 230 are evenly distributed under the storage platform 210 in a square array to provide stable support for the storage platform 210 .

[0042] In some embodiments, the feeding mechanism 200 further includes a fixed platform 240 connected to the frame 100. The fixed platform 240 is provided with holes adapted to the lifting guide 221 and the support rod 230 so that the lifting guide 221 and the support rod 230 pass through the fixed platform 240.

[0043] In some embodiments, a bearing 250 is provided at the port of the fixed platform 240 for passing the hole of the support rod 230. The support rod 230 passes through the bearing 250 on the fixed platform 240 to achieve a more stable movement and support effect.

[0044] In some embodiments, the first driver 222 is disposed on a fixing platform 240 .

[0045] See also Figure 3 , Figure 3 This is a partial structural diagram of the lifting component in one embodiment of the present application. In some embodiments, the lifting component includes a pin 310 and a second driver. The pin 310 is perpendicular to the plane of the storage table. The second driver is connected to the pin 310, and the second driver can drive the pin 310 to descend so that the pin 310 can pierce the first layer of multiple stacked pieces on the storage table 210. The second driver can also drive the pin 310 to rise to lift the piece 20 pierced by the pin 310. After the clamping component clamps the piece 20, the second driver can also drive the pin 310 to continue to rise to separate the pin 310 from the piece 20.

[0046] In some embodiments, the insertion pin 310 is positioned relative to the first working area so that the insertion pin 310 can be inserted into the middle section of the panel 20 located on the first working area.

[0047] See also Figure 4 , Figure 4 It is a partial structural diagram of the material dividing mechanism in one embodiment of the present application. In some embodiments, the clamping component includes a clamping arm and a third driver. Among them, the clamping arm is movably mounted on the synchronous frame 320. The clamping arm is used to grab the piece 20 lifted by the lifting component. The third driver can drive the clamping arm to slide along the synchronous frame 320 so that the clamping arm can grab the piece 20 at a set width, thereby ensuring that the piece 20 can maintain an unfolded state and avoid the piece 20 from curling in subsequent processes. It can be understood that in order to unfold the piece 20, the clamping arms of the two sets of clamping components should be arranged on both sides of the lifting component to grab both sides of the lifted piece 20.

[0048] In some embodiments, the clamping arm includes an upper clamping plate 331, a lower clamping plate 332, and an upper clamping plate driver 333. The upper clamping plate driver 333 is capable of driving the upper clamping plate 331 to move relative to the lower clamping plate 332 to tighten or loosen the panel 20. Furthermore, the lower clamping plate 332 is configured to have a preset height below the height of the panel 20 after it is lifted, while the upper clamping plate 331 is configured to have a preset height above the height of the panel 20 after it is lifted.

[0049] In some embodiments, in order to more efficiently and accurately unfold and grasp the cut piece 20, the initial positions of the two sets of clamping components are set relatively close to each other, so that when the clamping components move to the first working area with the synchronous frame 320, the two sets of clamping components can be close to the lifting device located between the two, thereby avoiding the situation where the edge of the cut piece 20 falls below the lower clamping piece due to the clamping components being far away from the middle of the cut piece 20. At this time, after the cut piece 20 is lifted and the synchronous frame 320 moves into place, it can be ensured that the cut piece 20 is located in the middle of the upper and lower clamping pieces. By driving the left and right clamping arms relatively apart by the third driver, the cut piece 20 can be gradually unfolded. When the third driver drives the clamping arms to move to the set position, the upper clamping plate driver 333 drives the upper clamping plate 331 to descend, thereby completing the gradual clamping of the cut piece 20. After the clipped piece 20 is moved to the second working area by the synchronous frame 320, the upper clamping plate driver 333 drives the upper clamping plate 331 to reset, so that the piece 20 is flattened on the adjustment table 420. After the transfer of the piece 20 is completed, the third driver drives the clamping arm to reset.

[0050] In some embodiments, the synchronization frame 320 has a horizontal first guide rail 321. The clamping component further includes a guide rail connector 334, and the clamping arm can be connected to the first guide rail 321 through the guide rail connector 334 and move along the guide rail.

[0051] In some embodiments, the first guide rail 321 includes two upper and lower parallel screw rods. The two grabbing components are respectively mounted on different screw rods via the guide rail connector 334.

[0052] In some embodiments, the first guide rail 321 includes two screw rods facing the same direction and arranged adjacent to each other. The two grabbing components are respectively installed on different screw rods through the guide rail connector 334.

[0053] In some embodiments, the frame 100 further includes a horizontally aligned guide rail assembly 110 and a fourth actuator. Both ends of the synchronization frame 320 are movably connected to the guide rail assembly 110. The fourth actuator can drive the synchronization frame 320 to move along the guide rail assembly 110 to move the synchronization frame 320 toward or away from the first working area and the second working area.

[0054] See also Figure 5 , Figure 5 In some embodiments, the image collector 410 is located on the expansion bracket 130 of the frame 100 so that the image collector 410 can have a larger image acquisition range.

[0055] See also Figure 6 , Figure 6 The diagram below is a partial structural diagram of a correction mechanism in one embodiment of the present application. In some embodiments, the adjustment platform 420 is located on the table 120 of the frame 100. The adjustment platform 420 in this application is a circular disk. Rotating the adjustment platform 420 adjusts the orientation of the cut piece 20 located on its surface. To prevent the center position of the cut piece 20 from shifting during rotation, the center of the adjustment platform 420 is designated as the second working area.

[0056] In some embodiments, the horizontal projection of the line connecting the center of the adjustment platform 420 and the center of the pin 310 is parallel to the guide direction of the guide rail assembly 110. In this case, after the grabbing assembly grabs the panel 20, it only needs to drive the synchronization frame 320 to move along the guide rail assembly 110 to align the middle section of the panel 20 with the second working area, that is, align the center of the panel 20 with the center of the circle, thereby preventing the panel 20 from shifting during rotation.

[0057] In some embodiments, the height difference between the surface of the adjustment platform 420 and the lower clamping plate 332 is set to be less than 3 cm to prevent the cutting piece 20 from curling again after the clamping member releases the cutting piece 20.

[0058] In some embodiments, the correction mechanism 400 further includes an annular ring 421. The annular ring 421 is located outside the adjustment platform 420 and serves to reinforce the outer ring.

[0059] In some embodiments, the image collector 410 further includes an image analysis component that analyzes the data collected by the image collector 410 to determine the orientation of the cut piece 20. If the orientation of the cut piece 20 does not meet a set requirement, the image analyzer controls the rotation of the adjustment stage 420 to adjust the cut piece 20 to the set orientation.

[0060] In some embodiments, the correction mechanism 400 further includes a rotating shaft 430 and a fifth actuator 440. The rotating shaft 430 is connected below the adjustment platform 420. The fifth actuator 440 drives the rotating shaft 430 to rotate, thereby rotating the adjustment platform 420 to adjust the orientation of the cut piece 20.

[0061] In some embodiments, the correction mechanism 400 further includes a coupling 460 , through which the fifth driver 440 and the rotating shaft 430 are connected.

[0062] In some embodiments, the correction mechanism 400 further includes a mounting plate 451 and a support base 452 connected to the frame 100. The support base 452 and the fifth driver 440 are disposed on the mounting plate 451.

[0063] In some embodiments, the automatic cutting piece feeding device 10 further includes a feeding robot. The feeding robot is used to move the cutting pieces adjusted by the correction mechanism to the sewing equipment.

[0064] In some embodiments, the automatic cutting piece feeding device 10 further includes a power switch, which can control the on and off of the power supply of the automatic cutting piece feeding device 10.

[0065] In some embodiments, the automatic cutting piece loading device 10 also includes a control console, which can control the automatic cutting piece loading device 10 to start the work process according to the set parameters, or control the various components of the automatic cutting piece loading device 10 to reset to the initial position, or stop all processes of the automatic cutting piece loading device 10.

[0066] Example 1

[0067] This embodiment illustrates one of the workflows of the automatic cutting piece loading device 10 of the present application for feeding, dividing, and correcting the cutting pieces 20 .

[0068] The staff places a stack of multiple cut pieces 20 on a designated area of ​​the storage table 210, sets the cut piece model and quantity via the console, and starts the workflow of the automatic cut piece loading device 10. The workflow of the automatic cut piece loading device 10 includes the feeding process, the material separation process, and the correction process.

[0069] After the workflow is started, the automatic cutting piece loading device 10 will first perform a feeding process, and the feeding process is as follows: the first driver 222 drives the storage table 210 to rise to the first working area to complete the feeding process.

[0070] After the feeding process, the automatic cutting piece feeding device 10 will repeat the steps of the material dividing process and the correction process according to the set number of cutting pieces to complete the processing of all the feeding cutting pieces.

[0071] The material division process is as follows: the second driver drives the pin 310 to descend to a set height, so that the pin 310 hooks the middle section of the cut piece 20. The second driver drives the pin 310 to rise to a set height, so that the cut piece 20 is lifted to the set height. The fourth driver drives the synchronous frame 320 to move to a set position, so that the cut piece 20 is located between the upper clamping plate 331 and the lower clamping plate 332 of the clamping arm. The third driver drives the clamping arm to move to a set position, and the cut piece 20 is gradually unfolded under the drive of the lower clamping plate 332. The upper clamping plate driver 333 drives the upper clamping plate 331 to descend, clamping the two ends of the cut piece 20. The second driver drives the pin 310 to rise to a set height, so that the pin 310 is separated from the cut piece 20. The fourth driver drives the synchronous frame 320 to move to a set position, so that the middle section of the clamped cut piece 20 is aligned with the second working area. The upper clamping plate driver 333 drives the upper clamping plate 331 to rise, loosening the ends of the cut piece 20 and laying the cut piece 20 flat on the second working area of ​​the sorting table. The fourth driver drives the synchronous frame 320 to reset, and the third driver drives the clamping arm to reset, completing the single material separation process.

[0072] The correction process is as follows: Image acquisition device 410 captures the orientation of piece 20 in the second working area. Image analysis components analyze the orientation of piece 20 and control fifth actuator 440 to rotate adjustment platform 420, adjusting piece 20 to the desired orientation, completing the correction process.

[0073] Whenever a correction process is completed, the loading robot will move the corrected cut piece 20 from the second working area to the sewing equipment.

[0074] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
