[0002] In textile production, after the fabric is rolled into rolls, it is usually necessary to use a palletizer to classify the rolls and place them on a stacking rack, and then store or transport them uniformly. There are still some problems with the existing roll palletizers. The rolls are sometimes divided into multiple categories according to their thickness, and the multiple categories of rolls are mixed and transported to the bottom of the palletizer through a roll conveyor belt. The existing roll palletizer uses a visual system to take pictures and classify them. For example, the invention name is a method for stacking rolls of non-uniform specifications, and the invention patent application with publication number CN117755762 A. This method requires a visual camera system, which has high cost, high equipment precision, and inconvenient maintenance. Some roll palletizers can only use grippers to grab the rolls, and then place the rolls on the stacking rack from above, which cannot be used on some stacking racks that are closed on the top.

It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0029] like Figure 1 and Figure 2 As shown, a cloth roll stacking device includes a frame 1, an X-axis displacement component 2, a Y-axis displacement component 3, a Z-axis displacement component 4, a clamping component 5, a weighing sensor 6 and a locking component 7. The frame 1 is a rectangular frame, and the frame 1 includes a rectangular frame at the top and four support columns 11 connected to the four corners of the rectangular frame. The Y-axis displacement component 3 is connected to the frame 1, and the Y-axis displacement component 3 includes two symmetrically arranged self-propelled trolleys 31. The self-propelled trolley 31 uses an existing hoist trolley, such as the hoist trolley produced by Shanghai Tuoqi Equipment Co., Ltd., item number: MT-01, which is suitable for The track type is 80-160mm. The self-propelled trolley 31 includes a self-propelled motor 311, a driving wheel connected to the self-propelled motor 311, and a driven wheel corresponding to the driving wheel. The rectangular frame of the frame 1 includes two first guide rails 11 and a second guide rail 12. The first guide rail 11 is arranged along the Y-axis direction. The driving wheel and the driven wheel are symmetrically arranged on both sides of the first guide rail 11 and roll on the first guide rail 11. The self-propelled motor 311 drives the driving wheel to roll through gears. When the self-propelled motor 311 is working, the two self-propelled trolleys 31 move in the same direction along the Y-axis on the first guide rail 11.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, the X-axis displacement assembly 2 is connected to the Y-axis displacement assembly 3, and the X-axis displacement assembly 2 includes a beam 21, a first slide 22 and a first displacement motor 23. The beam 21 extends along the X-axis direction and the two ends of the beam 21 are respectively connected to a self-propelled trolley 31, so that the two self-propelled trolleys 31 drive the beam 21 to move along the X-axis direction as a whole when working. A first screw rod is provided in the beam 21, and the first displacement motor 23 is used to drive the first screw rod to rotate. The first slide 22 is movably connected to the first screw rod, so that when the first screw rod rotates, it drives the first slide 22 to slide along the beam 21. The first slide 22 includes a base 221, a turntable 222 and a rotating motor 223. The base 221 is located at the upper part and is movably connected to the first screw rod. The turntable 222 is located at the lower part and is rotatably connected to the base 221 through an intermediate shaft. A gear ring is provided on the outer edge of the turntable 222. The rotating motor 223 is arranged in the base 221. A gear corresponding to the gear ring is provided on the output shaft of the rotating motor 223. The rotating motor 223 drives the turntable 222 to rotate through a multi-stage gear.

[0031] like Figure 1 and Figure 3 As shown, the Z-axis displacement assembly 4 is connected to the X-axis displacement assembly 2 through a weighing sensor 6. The Z-axis displacement assembly 4 adopts an existing electric cylinder. The Z-axis displacement assembly 4 includes a first cylinder body 41, a first piston rod 42, and a second displacement motor 43. The top of the first cylinder body 41 is connected to the bottom of the turntable 222 through a weighing sensor 6. There are three weighing sensors 6. The weighing sensor 6 adopts a LASCAUX Lijing 0.5tSQB-SS cantilever beam weighing sensor with a comprehensive accuracy of ±0.02%RO. The weighing sensor 6 is used to weigh the clamped cloth roll 9 and classify the cloth roll 9 according to the weight. The first piston rod 42 is movably connected to the first cylinder body 41. Under the drive of the second displacement motor 43, the first piston rod 42 moves upward or downward.

[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, the clamping assembly 5 is connected to the Z-axis displacement assembly 4, and the clamping assembly 5 includes a base 51, a first clamping plate 52, a second clamping plate 53 and a working motor 55. The base 51 is arranged horizontally, and a second screw rod is arranged in the base 51. The working motor 55 is connected to the second screw rod for driving the second screw rod to rotate. The first clamping plate 52 is connected to one end of the lower part of the base 51, and the second clamping plate 53 is movably connected to the second screw rod and thus movably connected to the base 51. When the second screw rod rotates, it drives the second clamping plate 53 to move back and forth along the base 51. When the second clamping plate 53 moves back and forth, it approaches or moves away from the first clamping plate 52. When the second clamping plate 53 moves toward the first clamping plate 52, the second clamping plate 53 and the first clamping plate 52 are used together to clamp the cloth roll 9. The second clamping plate 53 and the first clamping plate 52 clamp the cloth roll 9 from both ends, and the movable first stacking rack 91 is placed under the frame 1. There is no cover above the first stacking rack 91, and the end of the cloth roll conveyor belt is located below the frame 1. After the cloth roll conveyor belt conveys the cloth roll 9 to the end, the second clamping plate 53 and the first clamping plate 52 of the clamping assembly 5 clamp the cloth roll 9, and then the clamping assembly 5 is moved to the top of the bottom plate of the first stacking rack 91 under the joint work of the Z-axis displacement assembly 4, the Y-axis displacement assembly 3 and the X-axis displacement assembly 2. The second clamping plate 53 moves to the right and releases the cloth roll 9, so that the cloth roll 9 is placed on the first stacking rack 91. After the stacking device repeats the work, multiple cloth rolls 9 are stacked on the first stacking rack 91 (such as Figure 6 When the stack is full, the first stacking rack 91 is forked away as a whole by a forklift.

[0033] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, when two cloth rolls 9 of different weights need to be stacked, two first stacking racks 91 are provided, and after the clamping assembly 5 clamps the cloth roll 9 on the cloth roll conveyor belt, the weighing sensor 6 works to weigh the cloth roll 9 first, and then places the cloth roll 9 on the designated first stacking rack 91 according to the weight of the cloth roll 9. The weighing sensor 6 has high precision, and can stack cloth rolls of different weights separately, and classify the cloth rolls into multiple categories according to their different weights, with low classification cost and high work efficiency.

[0034] like Figure 4 , Figure 7 , Figure 8 and Fig. 9As shown, the first clamping plate 52 is movably connected to the base 51 by a hinge 54, so that the first clamping plate 52 can be folded outward, and the folding direction of the first clamping plate 52 is the same as the forward direction of the second clamping plate 53. A locking assembly 7 is provided at one end of the base 51 corresponding to the first clamping plate 52. The locking assembly 7 is used to press the first clamping plate 52 tightly. The existing hydraulic cylinder is adopted. The locking assembly 7 includes a second fixed cylinder 71 and a second piston rod 72. The second fixed cylinder 71 is obliquely arranged and connected to one end of the base 51. The second piston rod 72 is movably connected to the second fixed cylinder 71. After the second piston rod 72 extends out of the second fixed cylinder 71, the lower end of the second piston rod 72 presses against the back side of the first clamping plate 52 to prevent the first clamping plate 52 from folding. When the second piston rod 72 presses against the first clamping plate 52, the first clamping plate 52 is used to clamp the cloth roll 9. When the cloth roll 9 needs to be placed on the closed stacking rack 9 from the side, 2, the closed stacking rack 92 includes multiple storage bins. The top of the closed stacking rack 92 is blocked and the cloth roll 9 cannot be placed from top to bottom. The two sides of the storage bin are unblocked, and the cloth roll 9 can only enter and exit from the side. The X-axis displacement assembly 2 and the Y-axis displacement assembly 3 drive the clamping assembly 5 to move to the side of the closed stacking rack 92, and one end of the clamping assembly 5 enters the closed stacking rack 92. At this time, the second piston rod 72 slowly retracts into the second fixed cylinder 71, and the second clamping plate 53 moves forward under the drive of the working motor 55. One end of the cloth roll 9 falls into the stacking rack 92 and is pushed by the second clamping plate 53 to move into the closed stacking rack 92. The second clamping plate 53 pushes the entire cloth roll 9 into the storage bin of the closed stacking rack 92 to complete the stacking of the cloth rolls 9. After the entire closed stacking rack 92 is filled with cloth rolls 9, the closed stacking rack 92 is forked away as a whole by a forklift.

[0035] like Figure 1 , Figure 3 , Figure 5 and Fig.10 As shown, due to the Z-axis displacement component 4 and the turntable 222, through the rotation of the turntable 222, the Z-axis displacement component 4 and the clamping component 5 can rotate, so that the cloth roll conveyor belt can enter the bottom of the frame 1 from the front and back sides or the left and right sides of the frame 1. The clamping component 5 can clamp the cloth roll 9 on the cloth roll conveyor belt, and when stacking the cloth roll 9, the turntable 222 can also drive the clamping component 5 to any angle, and the stacking frame can be stacked at any position under the frame 1, and the clamping component 5 can reach it. When an unobstructed first stacking rack 91 is used, the X-axis displacement assembly 2, the Y-axis displacement assembly 3 and the Z-axis displacement assembly 4 drive the clamping assembly 5 to stack the cloth roll 9 on the first stacking rack 91 from above; when a closed stacking rack 92 with a shield on top is used, the X-axis displacement assembly 2, the Y-axis displacement assembly 3 and the Z-axis displacement assembly 4 drive the clamping assembly 5 to the side of the closed stacking rack 92, and under the action of the locking assembly 7 and the second clamping plate 53, the cloth roll 9 enters the closed stacking rack 92 from the side.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
