[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, as long as there is no conflict, the various embodiments of the present invention and the various features in the embodiments can be combined with each other, and the technical solutions formed are all within the protection scope of the present invention.

[0034] like Figure 1 and 2 As shown, the laser cutting automatic cloth stacking machine of the present invention comprises a frame 5 and a feeding unit 1 , a cutting unit 2 and a sorting unit 3 arranged on the frame 5 .

[0035] The feeding unit 1 is used to change the conveying direction of the raw material from the horizontal direction to the vertical direction. The cutting unit 2 is arranged on one side of the feeding unit 1, and is used to cut the raw material conveyed in the feeding unit 1. The cutting unit 2 includes a laser cutter 21 and a walking mechanism 22 connected to the laser cutter 21. The laser cutter 21 is used to cut the raw material conveyed in the vertical direction in the feeding unit 1. The sorting unit 3 is arranged below the cutting unit 2, and is used to convey the cut raw material to the workbench 4 in the horizontal direction.

[0036] Among them, the laser cutter 21 can be a laser head, which includes a laser emitter that can emit a laser beam onto the raw material to cut the raw material to obtain slices and a laser tube that transmits high energy to the laser emitter. The laser head can adopt the structure in the existing technology and will not be repeated here.

[0037] The cutting unit 2 also includes a dust suction device (not shown) arranged on the side corresponding to the laser head. When the laser head is cutting, the dust suction device will absorb the dust generated during cutting, so that there is no dust in the cutting process and the cut edge is cleaner, so the slices produced are of high quality.

[0038] Furthermore, the dust suction device is a dust suction tube, such as a negative pressure dust suction tube.

[0039] like Figure 1 As shown, the feeding unit 1 changes the direction of the raw material conveyed along the positive direction of the Y-axis to the negative direction of the Z-axis, and conveys it to the sorting unit 3. The laser cutter 21 can cut the raw material in the vertical direction. After the cutting is completed, the sorting unit 3 changes the conveying direction of the raw material to the positive direction of the Y-axis again, so that the initial conveying direction of the raw material is the same as the conveying direction after cutting. Therefore, the feeding unit 1 and the sorting unit 3 can be arranged in parallel in the X-axis direction and staggered with each other in the Z-axis direction, thereby utilizing the space in the Z-axis direction to reduce the footprint of the laser cutting automatic stacking machine.

[0040] like Figure 1 In the embodiment shown, there are two laser cutters 21, which are respectively arranged at the end and the middle of the feeding unit 1. The walking mechanism 22 is used to drive the two laser cutters 21 to move simultaneously along the axial direction of the walking mechanism 22. Figure 1 As shown, when cutting, the two laser cutters 21 are driven by the walking mechanism 22 to move along the positive direction of the X-axis, so that each laser cutter 21 only needs to move half of the width of the raw material to complete the cutting of the raw material; at the same time, the two laser cutters 21 only need to move along the negative direction of the X-axis during the next cutting to complete the cutting of the raw material again, thereby improving the cutting efficiency.

[0041] It should be noted that the raw material described in the present invention can be dust-free cloth, leather, leather or plastic.

[0042] In one embodiment, the cutting unit 2 further includes a first material clamping mechanism 23, both ends of which are connected to the linear reciprocating mechanism, and the first material clamping mechanism 23 is used to fix the raw material transported in the vertical direction. Figure 1 In the Z-axis direction, the first clamping mechanism 23 fixes the raw material in the Z-axis direction, thereby facilitating the laser cutter 21 to perform cutting work.

[0043] Specifically, if Figure 4 As shown, the first clamping mechanism 23 includes a connecting plate 231, a plurality of support plates 232 vertically arranged on the connecting plate 231, and a fixed plate 233 arranged on the other side of the support plate 232, wherein the connecting plate 231 and the fixed plate 233 are parallel and both extend in the horizontal direction (i.e., the X-axis direction), and the two ends of the connecting plate 231 are respectively arranged on both sides of the frame 5 and are connected to the linear reciprocating mechanism, and the linear reciprocating mechanism drives the connecting plate 231 and the support plate 232 to move in the negative direction of the Y-axis, that is, the connecting plate 231 moves in the direction close to the raw material, thereby pushing the raw material to the fixed plate for fixing, and the laser cutter 21 can perform cutting work at this time; when the cutting is completed, the linear reciprocating mechanism drives the connecting plate 231 and the support plate 232 to move in the positive direction of the Y-axis, that is, the connecting plate 231 moves in the direction away from the raw material, thereby the raw material is loosened, which is convenient for the sorting unit to perform subsequent work.

[0044] The linear reciprocating mechanism may be a synchronous pulley mechanism or a slider rail mechanism arranged on both sides of the frame 5. The synchronous pulley mechanism or the slider rail mechanism may adopt the structure in the prior art, which will not be described in detail here.

[0045] In one embodiment, the sorting unit 3 includes a pushing mechanism 31 and a second clamping mechanism 32 arranged in parallel. The pushing mechanism 31 and the second clamping mechanism 32 are both connected to the linear reciprocating mechanism. The pushing mechanism 31 is used to change the raw materials transported in the vertical direction to transported in the horizontal direction.

[0046] Specifically, the pushing mechanism 31 is arranged below the feeding unit 1, and the pushing mechanism 31 pushes the raw material after cutting along the positive direction of the Y-axis, so that the second clamping mechanism 32 can clamp the end (outer end) of the raw material. Then, the raw material can be moved along the positive direction of the Y-axis under the drive of the second clamping mechanism 32, so as to reach the workbench 4.

[0047] In order to ensure that the material pushing mechanism 31 and the second material clamping mechanism 32 operate simultaneously, both ends of the material pushing mechanism 31 and both ends of the second material clamping mechanism 32 are connected to the linear reciprocating mechanism.

[0048] like Figure 3 As shown, the second clamping mechanism 32 includes a cylinder mechanism 321, a clamping plate 322 connected to the cylinder mechanism 321, and a clamping plate cross beam 323 extending in the horizontal direction. The clamping plate 322 extends in the horizontal direction. Driven by the cylinder mechanism 321, the clamping plate 322 closes or opens in the vertical direction to clamp or release the end of the raw material transported in the horizontal direction. The two ends of the clamping plate cross beam 323 are respectively connected to the linear reciprocating mechanism, and the cylinder mechanism 321 is arranged on the clamping plate cross beam 323. Driven by the clamping plate cross beam 323, the cylinder mechanism 321 and the clamping plate 322 move along the negative direction of the Y axis. When the clamping plate 322 approaches the raw material, the cylinder mechanism 321 closes the clamping plate 322 and clamps the end of the raw material. Then, driven by the clamping plate cross beam 323, the cylinder mechanism 321 and the clamping plate 322 move along the positive direction of the Y axis and pull the raw material onto the workbench 4.

[0049] When the clamping plate cross beam 323 moves driven by the linear reciprocating mechanism, it has limit mechanisms in both the positive and negative directions of the Y axis. The limit mechanism can be a mechanical limit mechanism, such as a limit slot, or an electrical limit mechanism, such as a limit switch, which is electrically connected to the linear reciprocating mechanism to control its limit position. Of course, it can also be a combination of a mechanical limit mechanism and an electrical limit mechanism.

[0050] Furthermore, both ends of the workbench 4 are connected to the vertical lifting mechanism, and the vertical lifting mechanism is electrically connected to the cylinder mechanism 321. When the raw material reaches the workbench 4 along with the cylinder mechanism 321 and the clamping plate 322, the cylinder mechanism 321 opens the clamping plate 322, so that the raw material stays on the workbench 4. At the same time, the vertical lifting mechanism receives the action signal of the cylinder mechanism 321, and drives the workbench 4 to move downward (negative direction of the Z axis), so that the raw material on the workbench 4 is slightly lowered by a certain distance in the Z axis direction, so that the cylinder mechanism 321 and the clamping plate 322 can return to the original path and clamp the next raw material without interfering with the raw material already on the workbench 4.

[0051] The vertical lifting mechanism can adopt structures in the prior art such as a motor mechanism, a synchronous belt mechanism or a screw mechanism, which will not be described in detail here.

[0052] Furthermore, the workbench 4 is a conveyor belt that transports raw materials in a horizontal direction. When the raw materials move along the positive direction of the Y axis together with the cylinder mechanism 321 and the clamping plate 322, the workbench 4 also transmits along the positive direction of the Y axis to prevent the raw materials from rubbing on the workbench 4 and damaging the surface of the raw materials.

[0053] In one embodiment, Figure 2As shown, the feeding unit 1 includes a raw material roller 11, a conveying roller 12 arranged above the raw material roller 11, and a clamping roller 13 arranged below the conveying roller 12. The axes of the raw material roller 11, the clamping roller 13 and the conveying roller 12 are parallel to each other. The raw material roller 11 and the laser cutter 21 are respectively arranged on both sides of the conveying roller 12. The raw material can be smoothly conveyed to the clamping roller 13 through the conveying roller 12.

[0054] exist Figure 2 In the illustrated embodiment, the axial directions of the raw material roller 11, the conveying roller 12 and the clamping roller 13 are all along the X-axis direction. The raw material roller 11 is lower than the conveying roller 12 in the Z-axis direction. The number of conveying rollers 12 is 4-6 and they are arranged in sequence along the Y-axis direction. The clamping roller 13 is arranged below one of the frontmost conveying rollers 12. The clamping roller 13 is two rotating rollers with opposite rotation directions. The raw material enters between the two rotating rollers and is conveyed. The rotating roller is the output end of the feeding unit 1, and the raw material outputted by it falls onto the pushing mechanism.

[0055] The raw material is transported from the raw material roller 11 through the conveying roller 12 to the clamping roller 13, wherein the raw material is transported along the positive direction of the Y axis on the conveying roller 12, and is transported along the negative direction of the Z axis after entering the clamping roller 13, that is, the direction of the raw material changes by 90 degrees after entering the clamping roller 13 from the conveying roller 12, and the cut raw material is pushed out by the pushing mechanism 31, so that the second clamping mechanism 32 clamps and pulls it to be transported along the positive direction of the Y axis, thereby changing the angle of the raw material by 90 degrees again, making its conveying direction the same as the initial conveying direction in the feeding unit 1, which can maximize the use of space and make the laser cutting automatic cloth stacking machine occupy a smaller area.

[0056] The raw material roller 11 and the workbench 4 are respectively arranged on both sides of the conveying roller 12, that is, the raw material roller 11 is arranged on the rear side of the frame 5, and the workbench 4 is arranged on the front side of the frame 5. The raw material roller 11 includes an air expansion shaft 111 arranged on the rear side of the frame 5 and a magnetic powder controller 112 arranged at the end of the air expansion shaft 111. The air expansion shaft 111 rotates under the drive of the motor to realize the feeding function, and the magnetic powder controller 112 is used to control the motor.

[0057] The frame 5 is also provided with a control display screen 52 for displaying the operating parameters of the laser cutting automatic stacking machine. The frame 5 is also provided with a control display screen 52 and a control button 53 for controlling the start and stop of the laser cutting automatic stacking machine. In addition, the frame 5 is also provided with a control unit, which is electrically connected to the walking mechanism 22, the linear reciprocating mechanism and the vertical lifting mechanism to control their operation.

[0058] The working process of the laser cutting automatic cloth stacking machine described in the present invention is described in detail below.

[0059] like Figure 4As shown, the raw material roller 11 rotates to convey the raw material S to the conveying roller 12. After the raw material S is conveyed in the positive direction along the Y axis by the conveying roller 12, it enters the clamping roller 13. The clamping roller 13 conveys the raw material S in the negative direction along the Z axis and reaches the pushing mechanism 31.

[0060] The linear reciprocating mechanism drives the connecting plate 231 and the supporting plate 232 to move along the negative direction of the Y axis, pushing the raw material S onto the fixing plate 233 for fixing. The laser cutter 21 moves along the X axis direction driven by the walking mechanism 22 to cut the raw material S.

[0061] The linear reciprocating mechanism drives the connecting plate 231 and the supporting plate 232 to move along the positive direction of the Y axis to loosen the raw material S. The pushing mechanism 31 moves along the positive direction of the Y axis to push the cut raw material S. At the same time, the cylinder mechanism 321 is actuated to close the clamping plate 322 and clamp the outer end of the raw material S.

[0062] Driven by the clamping plate cross beam 323 , the cylinder mechanism 321 and the clamping plate 322 move along the positive direction of the Y axis, and the workbench 4 is transported along the positive direction of the Y axis, so that the raw material S is located on the workbench 4 .

[0063] The cylinder mechanism 321 is actuated to open the clamping plate 322 and release the raw material S, and the vertical lifting mechanism drives the workbench 4 to move along the negative direction of the Z axis, so that the raw material on the workbench 4 is slightly lowered by a certain distance in the Z axis direction.

[0064] Driven by the clamping plate cross beam 323, the cylinder mechanism 321 and the clamping plate 322 move along the negative direction of the Y axis to clamp the next raw material S. In this way, multiple regular raw materials S can be stacked together in the Z axis direction.

[0065] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no conflict.
