Description

Technical Field

[0001] The present invention relates to the field of clothing machinery, in particular to an automatic fabric layering mechanism for facilitating a fabric grabbing mechanism to grab a single-layer fabric, a single-layer fabric grabbing device, and an automatic coding machine using the automatic fabric layering mechanism and the single-layer fabric grabbing device and a cloth turning method of the coding machine. Background Art

[0002] When a garment factory cuts fabric, they stack the fabric in multiple layers, then mark a code on each layer of fabric, and then use a machine to cut all the fabrics according to the cutting route designed by a computer.

[0003] Currently, all garment factories are equipped with dedicated coders. Coding fabrics is a labor-intensive and boring job.

[0004] There are two ways of working: one is that the coder turns the fabric with one hand and codes with the other hand; the other is that the coder turns the fabric manually and the machine codes it. The problems with these two methods are low work efficiency and high work intensity of the coders, resulting in many coders developing occupational diseases.

[0005] A better solution is to turn the fabric by machine and apply coding by machine. The existing machine turning and coding equipment on the market has the problem of grabbing multiple layers of fabric at one time. Once multiple layers are grabbed at one time, it will directly cause code skipping, and eventually lead to the scrapping of the entire batch of cut fabrics.

[0006] Therefore, how to automatically layer the fabric and grab only a single layer of fabric each time the machine grabs the fabric has become a technical problem that needs to be solved urgently in the industry. Summary of the invention

[0007] The applicant has conducted research and improvements on the above existing problems.

[0008] The object of the present invention is to provide an automatic fabric layering mechanism that enables the fabric grabbing mechanism to grab only a single layer of fabric each time, thereby avoiding the occurrence of code jumping events, and at the same time can effectively reduce the strength of the coder's fingers turning the fabric.

[0009] This technical solution:

[0010] An automatic fabric layering mechanism includes a pressing mechanism for pressing a fabric, wherein the pressing mechanism presses the fabric so that the pressed part of the fabric is in a relatively fixed state; the pressure exerted by the pressing mechanism on the fabric is greater than the pressure exerted by the touch part on the fabric; the touch part of the fabric layering mechanism presses the fabric and moves to the pressing mechanism, that is, the touch part drives the pressed fabric to move toward the pressing mechanism, and during the process of the touch part pressing the fabric and moving to the pressing mechanism, the friction between the touch part and the pressed first fabric is greater than the friction between the first fabric and the second layer of fabric adjacent to the first fabric; the touch part may press the fabric to translate toward the pressing mechanism; or the touch part may press the fabric to rotate and approach the pressing mechanism; the touch part contacts the fabric and layers the fabric through sliding friction. That is, the fabric part contacted by the touch part of the fabric layering mechanism and the fabric part pressed by the pressing mechanism form a relative displacement; thereby the fabric between the touch part of the fabric layering mechanism and the pressing mechanism is layered.

[0011] In the above solution, the contact portion of the fabric layering mechanism translates toward the pressing mechanism.

[0012] In the above solution, the contact portion of the fabric layering mechanism rotates toward the pressing mechanism.

[0013] In the above solution, the contact surface between the touch portion and the fabric is a rough surface.

[0014] In the above solution, the roughness of the contact surface of the touch portion and the pressure and contact area of ​​the touch portion are adjusted according to different fabric properties.

[0015] Another object of the present invention is to provide a single-layer fabric grabbing device.

[0016] This technical solution:

[0017] A single-layer fabric grabbing device comprises a central controller, a fabric layering mechanism, a fabric clamping mechanism and a detection sensing mechanism; the central controller controls the coordinated actions of the fabric layering mechanism, the fabric clamping mechanism and the detection sensing mechanism through signals.

[0018] The fabric layering mechanism comprises a pressing mechanism for pressing the fabric, wherein the pressing mechanism presses the fabric so that the pressed part of the fabric is in a relatively fixed state; the pressure exerted by the pressing mechanism on the fabric is greater than the pressure exerted by the touch part on the fabric; the touch part of the fabric layering mechanism presses the fabric and moves to the pressing mechanism, that is, the touch part drives the pressed fabric to move toward the pressing mechanism, and during the process of the touch part pressing the fabric and moving to the pressing mechanism, the friction between the touch part and the pressed first fabric is greater than the friction between the first fabric and the second layer of fabric adjacent to the first fabric; the touch part may press the fabric to translate toward the pressing mechanism; or the touch part may press the fabric to rotate and approach the pressing mechanism; the touch part contacts the fabric and layers the fabric through sliding friction. That is, the fabric part contacted by the touch part of the fabric layering mechanism and the fabric part pressed by the pressing mechanism form a relative displacement; thereby the fabric between the touch part of the fabric layering mechanism and the pressing mechanism is layered.

[0019] The cloth clamping mechanism includes a clamping arm A and a clamping arm B, wherein the clamping arm A is fixed on the fixing mechanism; the clamping arm B is rotatably connected to the clamping arm A, and the clamping arm B is connected to the lifting mechanism through a rocker arm; the central controller controls the lifting mechanism to rise or fall through a signal, thereby controlling the clamping or loosening of the cloth clamping mechanism. The detection sensing mechanism is fixed on the fixing mechanism, and is used to detect the displacement change of the tail of the clamping arm B; and judges whether the cloth clamping mechanism clamps the fabric and whether the clamped fabric is a single-layer fabric according to a preset value.

[0020] When the cloth clamping mechanism is in a clamping state, the detection sensing mechanism detects whether the cloth clamping mechanism clamps the fabric or whether the clamped fabric is a single layer; if the fabric clamped by the cloth clamping mechanism is not a single layer or the fabric is not clamped, a signal is transmitted back to the central controller and an alarm is triggered, and the automatic coding machine stops working. The detection sensing mechanism is a proximity switch or a sensor.

[0021] Another object of the present invention is to provide an automatic coding machine.

[0022] This technical solution:

[0023] An automatic coding machine includes a central controller, a cloth clamping mechanism, a pressing mechanism, and a fabric layering mechanism. The central controller controls the operation of the cloth clamping mechanism, the pressing mechanism, and the fabric layering mechanism through signals. The pressing mechanism includes a coding part and a pressing mechanism shell. The coding part is located in the pressing mechanism shell and can be raised and lowered in the pressing mechanism shell. After the pressing mechanism presses the fabric, the coding part of the pressing mechanism codes, and then the coding part rises and leaves the fabric, and the pressing mechanism shell is still pressed on the fabric; the pressing mechanism and the cloth clamping mechanism clamp the fabric and then rise as a whole. The cloth clamping mechanism includes a clamping arm A and a clamping arm B, and the clamping arm A is fixed on the fixing mechanism; the clamping arm B is rotatably connected to the clamping arm A, and the positions of the clamping arm A and the clamping mechanism are relatively fixed; the clamping arm B is connected to the lifting mechanism through a rocker arm. The contact part of the fabric layering mechanism presses the fabric and moves to the pressing mechanism, the contact part of the fabric layering mechanism contacts the fabric and delaminates the fabric between the contact part and the housing of the coding machine through sliding friction; after the cloth clamping mechanism clamps the first layer of fabric between the contact part and the housing of the coding machine; the pressing mechanism releases the clamped fabric, and the cloth clamping mechanism carries the first layer of fabric to the cloth dropping area. Among them, the cloth clamping mechanism, the pressing mechanism, and the fabric layering mechanism can be connected to the fixing mechanism. The fixing mechanism is slidably connected to the guide rail, and the guide rail is fixed on the fixing frame of the workbench. The fixing mechanism drives the cloth clamping mechanism, the pressing mechanism, and the layering mechanism to translate as a whole along the track.

[0024] In the above scheme, a clamping reinforcement member is further provided at the lower part of the clamping mechanism, and the clamping reinforcement member is fixed to the outer shell of the clamping mechanism. The reinforcement member compresses the fabric and shortens the distance between the contact part of the fabric layering mechanism and the clamping mechanism.

[0025] In the above scheme, a detection sensing structure is also provided; the detection sensing structure is fixed on the fixing mechanism and is used to detect the displacement of the tail of the clamping arm B. When the cloth clamping mechanism is in a clamping state, the detection sensing structure detects whether the fabric clamped by the cloth clamping mechanism is a single layer or whether the clamped fabric is a single layer; if the fabric clamped by the cloth clamping mechanism is not a single layer or the fabric is not clamped, the signal is transmitted back to the central controller and an alarm is triggered, and the automatic coding machine stops working.

[0026] In the above solution, the detection sensing mechanism is a proximity switch or a sensor.

[0027] In the above solution, the clamping mechanism may only have a clamping function, or may be a composite mechanism including a clamping function and a coding function.

[0028] Another object of the present invention is to provide a method for automatically turning cloth by a coding machine.

[0029] This technical solution:

[0030] A method for automatically turning cloth by a coding machine, firstly, a central controller issues an instruction so that a pressing mechanism and a fabric layering mechanism both press the fabric; then the pressing mechanism presses the fabric and does not move, and the fabric layering mechanism presses the fabric and drives the pressed fabric to move toward the pressing mechanism, and the friction between the contact part of the fabric layering mechanism and the pressed first layer of fabric is greater than the friction between the first layer of fabric and the second layer of fabric, so that at least part of the fabric pressed by the fabric layering mechanism is displaced relative to the pressing mechanism, thereby causing the fabric between the pressing mechanism and the fabric layering mechanism to arch; then the central controller issues an instruction to control the cloth clamping mechanism to start the cloth clamping action, and when the cloth clamping action of the cloth clamping mechanism is completed, the central controller issues an instruction again to judge whether the cloth clamping mechanism clamps the fabric and whether it clamps a single layer of fabric through a detection sensing mechanism;

[0031] If the detection sensing mechanism determines that the fabric clamping mechanism does not clamp the fabric, that is, the thickness of the clamped fabric is not within the preset range, the detection sensing mechanism returns a signal to the central controller, and the central controller immediately issues an instruction to sound an alarm and instruct various components of the coding machine to stop working.

[0032] If the detection sensing mechanism determines that the fabric clamping machine clamps the fabric, but the thickness of the clamped fabric exceeds the preset range, the detection sensing mechanism returns a signal to the central controller, and the central controller immediately issues an instruction to sound an alarm and instruct all components of the coding machine to stop working.

[0033] If the detection sensing mechanism determines that the fabric clamped by the cloth clamping mechanism is a single layer, that is, the thickness of the clamped fabric is within a preset range, the detection sensing mechanism sends a signal back to the central controller, and the central controller issues an instruction to raise the clamping mechanism, and the cloth clamping mechanism moves the clamped fabric to the cloth dropping area with the clamped fabric and releases the clamped fabric in the cloth dropping area, and then each mechanism is reset and the action is repeated.

[0034] The beneficial effects of the present invention are as follows:

[0035] 1. The automatic fabric layering mechanism of the present invention has the advantages of small size and accurate fabric wrinkling and layering.

[0036] 2. The automatic coding machine of the present invention can effectively reduce the situation of missing codes.

[0037] 3. It can effectively reduce the intensity of employees’ work. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] Combine the following Figure 1 Further explanation of the present invention

[0057] An automatic fabric layering mechanism 200 includes a pressing mechanism 1 for pressing fabric, a fabric layering mechanism 4 and a fixing mechanism (not shown in the figure). The pressing mechanism 1 and the fabric layering mechanism 4 are both fixedly connected to the fixing mechanism.

[0058] The pressing mechanism 1 presses the upper surface 51 of the fabric 5, and the pressed part of the fabric 5 is in a relatively fixed state; the contact part 41 of the fabric stratification mechanism 4 presses the fabric 5 to rotate and approach the pressing mechanism 1, and the contact part 41 contacts the upper surface 51 of the fabric 5. The friction force between the contact part 41 and the upper surface 51 of the fabric 5 is greater than the friction force between the first layer of fabric and the second layer of fabric adjacent to the first layer of fabric, thereby stratifying the fabric through sliding friction.

[0059] Embodiment 2:

[0060] Combine the following Figure 2-6 Further explanation of the present invention

[0061] An automatic coding machine comprises a fixing mechanism 3, a cloth clamping mechanism 2, a pressing mechanism 1 and a layering mechanism 4.

[0062] The cloth clamping mechanism 2, the pressing mechanism 1, and the layering mechanism 4 are connected to the fixing mechanism 3 through components such as cylinders.

[0063] The fixing mechanism 3 is slidably connected to the guide rail 63 , and the guide rail 63 is fixed on the fixing frame 62 of the workbench 61 .

[0064] The clamping mechanism 1 includes a coding part 10 and a clamping mechanism housing 11. The clamping mechanism 1 is connected to the number machine coding cylinder 73. The coding part 10 is located in the clamping mechanism housing 11. The clamping mechanism 1 only moves left and right with the fixing mechanism 3 as a whole. An L-shaped clamping reinforcement member 12 is fixed to the lower part of the clamping mechanism housing 11.

[0065] The cloth clamping mechanism 2 includes a clamping arm A21, a clamping arm B22 and a rocker arm 23. The clamping arm A21 is fixed on the fixed block 31 of the fixing mechanism 3; the clamping arm B22 is connected to the clamping arm A21 through an axis rotation, the clamping arm A21 and the clamping mechanism 1 are relatively fixed in position, and the clamping arm A21 only moves left and right with the fixing mechanism 3 as a whole; the clamping arm B22 is connected to the clamp tensioning cylinder 77 through the rocker arm 23; the clamp tensioning cylinder 77 is fixed on the fixing mechanism 3; the fixed block 31 is connected to the clamp lifting cylinder 76, and the clamp lifting cylinder 76 drives the cloth clamping mechanism 2 to move up and down. The clamp tensioning cylinder 77 controls the clamping arm B22 and the clamping arm A21 of the cloth clamping mechanism 2 to tighten or loosen. The end of the clamping arm A21 is close to the L-shaped end 12a of the clamping reinforcement 12 and the position is fixed.

[0066] After the overall lifting module 72 drives the fixing mechanism 3 downward to its position, the pressing mechanism 1 presses the fabric 5, and the numbering machine coding cylinder 73 drives the coding part 10 of the pressing mechanism 1 to code. Then the numbering machine coding cylinder 73 drives the coding part 10 to rise and leave the fabric, and the pressing mechanism shell 11 is still pressed on the fabric 5.

[0067] After the lifting cylinder 74 drives the fabric layering mechanism 4 downward to its position, the rotating cylinder 75 drives the contact part 41 of the layering mechanism 4 to rotate, and the contact part 41 contacts the fabric of the first layer. The rotation of the contact part 41 forms a sliding friction force with the fabric, so that the fabric between the contact part 41 and the pressing mechanism shell 11 is wrinkled and layered.

[0068] After the clamp lifting cylinder 76 drives the cloth clamping mechanism 2 downward to the position, the clamp tensioning cylinder 77 moves upward to drive the clamp arm B22 to clamp the wrinkled and layered first layer of fabric.

[0069] A detection sensing structure 9 is fixed on the fixed block 32 of the fixing mechanism 3. The detection sensing structure 9 is used to detect the displacement of the tail of the clamping arm B22; the detection sensing structure 9 is a proximity switch 91a and a proximity switch 91b. When the cloth clamping mechanism 2 is in a clamped state, the proximity switch 91a detects whether the cloth clamping mechanism 2 clamps the fabric. If it is detected that the fabric 5 is not clamped between the end 21a of the clamping arm A21 of the cloth clamping mechanism 2 and the end 22a of the clamping arm B22, the signal is transmitted back to the central controller and an alarm is triggered, and the automatic coding machine stops working. If the proximity switch 91a detects that the cloth clamping mechanism 2 clamps the fabric 5, the proximity switch 91b works to check whether the clamped fabric 5 is a single layer; if the fabric clamped by the cloth clamping mechanism 2 is not a single layer, the signal is transmitted back to the central controller and an alarm is triggered, and the automatic coding machine stops working.

[0070] After the integral lifting module 72 drives the fixing mechanism 3 to move upward to the right position, the left and right moving cylinders 71 drive the fixing mechanism 3 to move, move the clamped fabric to the fabric drop area, and the clamp tensioning cylinder 7 drives the clamp arm B22 to move, loosening the fabric. The remaining cylinders are reset, and the reciprocating action is repeated.

[0071] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. The present invention may be modified in any form without violating the basic structure of the present invention.
