Description

Technical Field

[0001] This invention relates to the field of textile processing, and in particular to an automatic processing equipment for duvet covers. Background Technology

[0002] The textile industry is the sector that processes natural and chemical fibers into various yarns, silks, threads, tapes, fabrics, and their dyed and finished products. With the development of the textile industry, in order to improve manufacturing efficiency, more and more textile products are being produced automatically using related equipment. However, in the process of making duvet covers, which requires a large amount of fabric and multiple layers of processing, the degree of automation in the duvet cover manufacturing process is not high.

[0003] The current process for manufacturing duvet covers is as follows: First, rolls of fabric are pulled out and laid flat; then, the two sides of the fabric are cut along its length to meet the width requirements; next, the fabric is cut along its width to the set length to obtain the duvet cover; finally, to prevent the fabric from fraying, the cut sides are sewn together. In this process, workers first lay the fabric flat on a work surface, then use a cutting machine to cut out the required shapes, followed by sewing and edge finishing by another worker. The entire duvet cover manufacturing process requires multiple workers to cooperate, resulting in low automation and low production efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide an automated duvet cover processing device to address the problems of low automation and low production efficiency in the duvet cover processing process.

[0005] An automatic duvet cover processing device includes a control unit, a sequentially arranged edge-cutting unit, a slitting and sewing unit, and a material collection unit, wherein:

[0006] One end of the fabric passes through the edge-cutting unit and is then fixed to the slitting and sewing unit;

[0007] The receiving unit is communicatively connected to the control unit and is used to grab the fabric on the cutting and sewing unit and move the fabric a preset distance in a direction away from the cutting and sewing unit.

[0008] The edge-cutting unit is communicatively connected to the control unit and is used to cut off the side edge of the fabric along the length direction of the fabric when the fabric is moved.

[0009] The cutting and sewing unit is communicatively connected to the control unit and is used to cut the fabric along a first direction after the fabric stops moving, and then sew the fabric remaining on the cutting and sewing unit along the first direction, wherein the first direction is perpendicular to the direction of movement of the fabric.

[0010] The aforementioned automated duvet cover processing equipment uses a receiving unit to grab the fabric and move it a preset distance, ensuring that the fabric length on the side of the cutting and sewing unit closest to the receiving unit meets the designed length of the duvet cover. An edge-cutting unit removes the side edges of the fabric, ensuring that the fabric after edge trimming meets the required width of the duvet cover. The cutting and sewing unit then cuts the fabric before sewing the remaining fabric, thus automating the duvet cover processing. Compared to existing manual duvet cover processing methods, this equipment improves production efficiency and reduces the labor intensity of operators.

[0053] See Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides an automatic duvet cover processing device 10, applied in the textile field. The automatic duvet cover processing device 10 includes a control unit, a cutting edge unit 100, a slitting and sewing unit 200, and a receiving unit 300 arranged sequentially. The control unit can be a PLC control cabinet, wherein:

[0054] One end of the fabric passes through the edge-cutting unit 100 and is then fixed to the slitting and sewing unit 200. In a specific setup, the rolled fabric is laid flat and one end of the fabric passes through the edge-cutting unit 100 and is then fixed to the slitting and sewing unit 200.

[0055] The receiving unit 300 is communicatively connected to the control unit. The receiving unit 300 is used to grab the fabric on the cutting and sewing unit 200 and move the fabric a preset distance away from the cutting and sewing unit 200. With the above settings, when the receiving unit 300 grabs the fabric and moves the fabric, the fabric is also conveyed along the cutting unit 100 toward the receiving unit 300. In specific settings, the preset distance that the receiving unit 300 moves the fabric is the required length of the duvet cover.

[0056] The edge-cutting unit 100 is communicatively connected to the control unit. The edge-cutting unit 100 is used to cut off the side edge of the fabric along the length direction of the fabric when the fabric is moving. With the above settings, the length direction of the fabric is as shown in the second direction b in the figure, which ensures that the fabric after the side edge is cut can meet the required width of the duvet cover.

[0057] The cutting and sewing unit 200 is communicatively connected to the control unit. The cutting and sewing unit 200 is used to cut the fabric along the first direction a after the fabric stops moving and then sew the fabric remaining on the cutting and sewing unit 200 along the first direction a. The first direction a is perpendicular to the direction of fabric movement.

[0058] In actual operation, the receiving unit 300 first grabs the fabric from the slitting and sewing unit 200 and moves the fabric a preset distance along the direction of the slitting and sewing unit 200 towards the receiving unit 300. The preset distance is the required length of the duvet cover, so that the length of the fabric on the side of the slitting and sewing unit 200 near the receiving unit 300 meets the required length of the duvet cover. While the fabric is moving, the edge trimming unit 100 simultaneously cuts off the side edges of the fabric, ensuring that the fabric after the side edges are trimmed meets the required width of the duvet cover. Then, the slitting and sewing unit 200 moves the fabric along the first direction a, i.e., the fabric... The fabric is cut in the width direction so that the portion of the fabric picked up by the receiving unit 300 meets the length and width requirements of the duvet cover. Then, the fabric retained in the slitting and sewing unit 200 is sewn to automate the duvet cover processing. By repeating the above operation, the entire piece of fabric can be processed. It should be noted that when processing a piece of fabric begins, the side of the fabric on the side away from the slitting and sewing unit 200 of the edge-cutting unit 100 will be cut off. Only when the fabric from the edge-cutting unit 100 to the slitting and sewing unit 200 has undergone one cycle has the side cut off to meet the width requirements.

[0059] The aforementioned automatic duvet cover processing equipment 10, by setting up a receiving unit 300 to grab the fabric and move the fabric a preset distance, ensures that the length of the fabric on the side of the cutting and sewing unit 200 near the receiving unit 300 meets the length of the duvet cover design; by using the edge cutting unit 100 to cut off the side edges of the fabric, it ensures that the fabric after cutting the side edges can meet the required width of the duvet cover; by using the cutting and sewing unit 200 to cut the fabric, the fabric remaining in the cutting and sewing unit 200 is then sewn to achieve automation of duvet cover processing; compared with the existing duvet cover processing, which all uses manual operation, it improves production efficiency and reduces the labor intensity of operators.

[0060] In the process of processing duvet covers, there is also the operation of yoke marking. Currently, yoke marking is done after the side edges of the fabric are cut, and then the yoke is marked on the fabric. It should be noted that yoke marking generally refers to making positioning marks on the fabric, which can be done by cutting a marked positioning hole or punching a hole at a designated location on the fabric. To improve production efficiency and automate yoke marking, in a preferred embodiment, the duvet cover automatic processing equipment 10 further includes a positioning unit 400. One end of the fabric passes sequentially through the edge-cutting unit 100 and the positioning unit 400 and is then fixed to the slitting and sewing unit 200. The positioning unit 400 is located between the edge-cutting unit 100 and the slitting and sewing unit 200. The positioning unit 400 is communicatively connected to the control unit. The positioning unit 400 is used to control the positioning unit 400 to yoke the fabric at a preset position after the fabric stops moving and before the slitting and sewing unit 200 starts working.

[0061] To facilitate the marking work of the positioning unit 400 at designated locations, the positioning unit 400 specifically includes a positioning frame 410, a first cutting pin module 420, and a first drive module 450, wherein:

[0062] The first cutting pin module 420 is slidably connected to the positioning frame 410 along the first direction a, and the first cutting pin module 420 is communicatively connected to the control unit. The first cutting pin module 420 is used to mark the yoke position on the fabric. In a specific setting, the first cutting pin module 420 is provided with a first slider 430, and the positioning frame 410 is equipped with a first slide rail 440 that cooperates with the first slider 430 and extends along the first direction a.

[0063] The first drive module 450 is disposed on the positioning frame 410. The first drive module 450 is communicatively connected to the control unit. The first drive module 450 is used to drive the first cutting pin module 420 to move along the first direction a to a preset position. In a specific setting, the first drive module 450 can be a motor. In actual operation, the output end of the first drive module 450 is connected to the first slider 430, driving the first slider 430 and the first cutting pin module 420 connected to the first slider 430 to move along the first direction a, so that the first cutting pin module 420 can mark the fabric at the preset position.

[0064] In the specific configuration, there are two first shearing pin modules 420, which are spaced apart along the first direction a and are slidably connected to the positioning frame 410 along the first direction a. Therefore, the positioning frame 410 is provided with two first slide rails 440 spaced apart along the first direction a, and each of the two first shearing pin modules 420 is provided with a first slider 430. There are also two first drive modules 450, each connected to a first slider 430. The control unit can simultaneously control the two first drive modules 450 to drive the two first sliders 430 connected to them to move on the first slide rails 440, so that the two first shearing pin modules 420 connected to the two first sliders 430 respectively reach the preset position simultaneously.

[0065] To facilitate the yoke setting of the first shearing pin module 420, more specifically, the first shearing pin module 420 includes a first connecting plate 421, a first shearing component, a first pin component, a first driving assembly, and a second driving assembly, wherein:

[0066] The first connecting plate 421 is slidably connected to the positioning frame 410 along the first direction a, and the first connecting plate 421 is connected to the first shearing member and the first pin member that can move up and down. In a specific setting, the first connecting plate 421 is connected to the first slider 430, and the first connecting plate 421 is also provided with a second slide rail extending in the vertical direction. The first pin member is provided with a second slider that matches the second slide rail.

[0067] The output end of the first drive component is connected to the first shearing component, and the first drive component is communicatively connected to the control unit. The first drive component is used to drive the first shearing component to open and close after the first shearing pin module 420 reaches the preset position, thereby realizing the cutting and marking of the fabric at the preset position. In specific settings, the first drive component can be a cylinder, motor or other drive component.

[0068] The second drive assembly is disposed on the first connecting plate 421 and is communicatively connected to the control unit. The second drive assembly is used to drive the first pin to move up and down relative to the first connecting plate 421 when the first shearing piece cuts the fabric. In a specific configuration, the second drive assembly can be a motor. In actual operation, the output end of the second drive assembly is connected to the second slider, driving the second slider and the first pin connected to the second slider to move up and down, thereby enabling the first pin to punch and mark the fabric. Alternatively, the control unit can control the second drive assembly to drive the first pin to move up and down before and after the first shearing piece cuts the fabric to achieve punching and marking of the fabric. To improve efficiency, the first shearing piece often operates simultaneously.

[0069] Combination Figure 4As shown, in order to more conveniently produce duvet covers of different widths, in a preferred embodiment, the trimming unit 100 includes a trimming frame 110, a first cutting module 120, and a second driving module, wherein:

[0070] The first cutting blade module 120 is slidably connected to the edge trimming frame 110 along the first direction a, and the first cutting blade module 120 is communicatively connected to the control unit. The first cutting blade module 120 is used to cut the side edge of the fabric along the length direction of the fabric. In a specific setting, the first cutting blade module 120 is provided with a third slider, and the edge trimming frame 110 is equipped with a third slide rail that cooperates with the third slider and extends along the first direction a.

[0071] The second drive module is mounted on the edge-cutting frame 110 and is communicatively connected to the control unit. The second drive module drives the first cutter module 120 to move along the first direction a. In operation, the output of the second drive module is connected to the third slider, causing the third slider and the first cutter module 120 connected to the third slider to move along the first direction a. This allows the first cutter module 120 to reach any position in the width direction of the fabric, and using this position as the starting point for edge cutting, the first cutter module 120 removes excess side edges along the length direction of the fabric.

[0072] In a specific configuration, the second drive module can be a motor, and the edge trimming unit 100 also includes a second cutter module 130. The second cutter module 130 and the first cutter module 120 are spaced apart along the first direction a. The second cutter module 130 is fixed to the edge trimming frame 110. By setting the position of the first cutter module 120 along the first direction a to be adjustable, the width of the fabric between the first cutter module 120 and the second cutter module 130 can be adjusted, thereby enabling the production of quilt covers of different widths.

[0073] To facilitate the edge cutting of the first cutting module 120 and the second cutting module 130, both the first cutting module 120 and the second cutting module 130 include an edge cutting blade, a bridging component, and an edge cutting motor. The bridging component is disposed on the edge cutting frame 110, and the edge cutting blade is mounted on the bridging component in a vertically movable manner. The edge cutting blade extends along the length of the fabric, specifically with a fourth slider on the edge cutting blade. The bridging component is also provided with a fourth slide rail extending vertically. The edge cutting motor is communicatively connected to the control unit, and the output end of the edge cutting motor is connected to the fourth slider. When the fabric moves, the edge cutting motor drives the fourth slider to move the edge cutting blade down to cut the fabric. The bridging component of the first cutting module 120 is provided with a third slider that slides in cooperation with the third slide rail of the edge cutting frame 110.

[0074] To ensure proper marking and positioning of the fabric, the trimming unit 100 specifically includes a pin module and a third drive module, wherein:

[0075] The pin module is slidably connected to the edge trimming frame 110 along the first direction a, and the pin module is communicatively connected to the control unit. The pin module is used to mark the yoke on the fabric. In a specific setting, the pin module is provided with a fifth slider, which cooperates with the third slide rail on the edge trimming frame 110.

[0076] The third drive module is located on the edge-cutting frame 110 and is communicatively connected to the control unit. The third drive module drives the pin module to move along the first direction a. In a specific configuration, the third drive module can be a motor. During operation, the output of the third drive module is connected to the fifth slider, causing the fifth slider and the pin module connected to it to move along the first direction a, thus enabling the pin module to mark the fabric at the required positions. The pin module is used for puncturing and positioning the fabric, which is existing technology and will not be discussed further here. With the above configuration, the control unit can simultaneously control the second and third drive modules to drive the first cutting pin module 420 and the pin module to mark the fabric after the first cutter module 120 has trimmed the fabric and before the slitting and sewing unit 200 has started operating.

[0077] To facilitate cutting and sewing of the fabric along the first direction a, in a preferred embodiment, the cutting and sewing unit 200 includes a fixing frame 210, a fourth drive module, a fifth drive module, a cutting module 220, and a sewing module 230, wherein:

[0078] The cutting module 220 and the sewing module 230 are spaced apart on the fixed frame 210 along the first direction a, and both the cutting module 220 and the sewing module 230 are slidably connected to the fixed frame 210 along the first direction a. In a specific configuration, the fixed frame 210 is provided with a fifth slide rail 240 extending along the first direction a, and the cutting module 220 and the sewing module 230 are respectively provided with a sixth slider and a seventh slider, which cooperate with the fifth slide rail 240. When the cutting and sewing unit 200 is not in motion in its initial state, the cutting module 220, the sewing module 230 and the fabric are arranged sequentially along the first direction a on the fixed frame 210.

[0079] The control unit is communicatively connected to the fourth drive module, the fifth drive module, the cutting module 220, and the sewing module 230. The control unit controls the fourth drive module to move the cutting module 220 along the first direction a and simultaneously controls the cutting module 220 to cut the fabric. The control unit also controls the fifth drive module to move the sewing module 230 along the first direction a and simultaneously controls the sewing module 230 to sew the fabric. In a specific configuration, the fixed frame 210 is equipped with a presser foot and a presser foot drive mechanism that can move up and down. The presser foot drive mechanism is communicatively connected to the control unit. Before the fabric moves, the presser foot moves upward, and after the fabric moves, the presser foot moves downward to press the fabric against the fixed frame 210. In actual operation, the output end of the fourth drive module is connected to the sixth slider, driving the sixth slider and the cutting module 220 connected to the sixth slider to move along the first direction a, realizing that the cutting module 220 cuts the fabric along the first direction a; the output end of the fifth drive module is connected to the seventh slider, driving the seventh slider and the sewing module 230 connected to the seventh slider to move along the first direction a, realizing that after the cutting module 220 cuts the fabric, the sewing module 230 sews the fabric and its edges along the first direction a. After the sewing module 230 finishes sewing, the sewing module 230 and the cutting module 220 return to their original positions under the control of the control unit; the positioning frame 410 and the fixing frame 210 can be connected as one unit.

[0080] To facilitate the cutting of fabric by the cutting module 220, specifically, the cutting module 220 includes a cutting blade, a third drive assembly, and a second connecting plate, wherein:

[0081] The second connecting plate is slidably connected to the fixed frame 210 along the first direction a, and a cutting blade that can move up and down is connected to the second connecting plate. In a specific setting, the second connecting plate is provided with a sixth slider that cooperates with the fifth slide rail 240, the cutting blade is provided with a connecting slider, and the second connecting plate is also provided with a connecting slide rail that extends in the vertical direction.

[0082] The third drive assembly is disposed on the second connecting plate and is communicatively connected to the control unit. The third drive assembly is used to drive the first cutter to move downward when the cutting module 220 moves along the first direction a. In a specific configuration, the third drive assembly can be a cutting motor. The output end of the third drive assembly is connected to the connecting slider. When the cutting module 220 moves, the third drive assembly drives the connecting slider to move the cutter to the cutting position.

[0083] Combination Figure 5As shown, to facilitate material collection, in a preferred embodiment, the material collection unit 300 includes a material collection frame 310 and a clamping module 320 disposed on the material collection frame 310. The clamping module 320 is communicatively connected to the control unit. Under the control of the control unit, the clamping module 320 grips the fabric on the cutting and sewing unit 200 and moves it at a preset distance. After the cutting and sewing unit 200 cuts the fabric, the clamping module 320 moves to a designated location to release the fabric. In a specific configuration, the preset distance by which the clamping module 320 moves the fabric is the required length of the duvet cover.

[0084] In order to facilitate the clamping module 320 to grasp the fabric and move it at a preset distance, the clamping module 320 specifically includes a clamping component 321, a fourth driving component 322 and a fifth driving component 323.

[0085] The clamping assembly 321 is slidably connected to the take-up rack 310 along the length of the fabric. In a specific configuration, the clamping assembly 321 includes a clamping claw 3211 and multiple spaced slide bars 3212 disposed on the clamping claw 3211. The slide bars 3212 extend along the length of the fabric, which is also the second direction b shown in the figure. The take-up rack 310 is provided with multiple sleeves that cooperate with the slide bars 3212. The number of sleeves is the same as the number of slide bars 3212.

[0086] The output end of the fourth drive component 322 is connected to the clamping component 321, and the fourth drive component 322 is communicatively connected to the control unit. The fourth drive component 322 is used to drive the clamping component 321 to switch between clamping and releasing states. In specific settings, the fourth drive component 322 can be a first cylinder, which is connected to the gripper 3211. The first cylinder controls the clamping and releasing of the gripper 3211.

[0087] The fifth drive assembly 323 is connected to the clamping assembly 321 and is communicatively connected to the control unit. The fifth drive assembly 323 is used to drive the clamping assembly 321 to move along the length of the fabric. In a specific setting, the fifth drive assembly 323 is a take-up cylinder. The output end of the take-up cylinder is connected to the slide bar 3212. The take-up cylinder drives the slide bar 3212 and the gripper 3211 connected to the slide bar 3212 to move along the second direction b. In actual operation, the receiving cylinder first drives the slide bar 3212 to move the gripper 3211 along the second direction b to the cutting and sewing unit 200. The first cylinder then drives the gripper 3211 to grab the fabric. Then the receiving cylinder drives the slide bar 3212 to move the gripper 3211 a preset distance away from the cutting and sewing unit 200 and then stops. In order to make it easier to make the movement of the clamping component 321 a preset distance each time, the length that the first cylinder can drive the slide bar 3212 to extend along the second direction b is the length required for the duvet cover. To facilitate the movement of the clamping assembly 321 to a designated location to release the fabric after it has been cut by the cutting and sewing unit 200, the clamping module 320 also includes a take-up motor, a take-up slider, and a take-up rail 324. The take-up slider is mounted on the clamping assembly 321, and the take-up rail 324 extends along the second direction b and is fixed to the take-up frame 310. The output end of the take-up motor is connected to the take-up slider, and the take-up motor is communicatively connected to the control unit. The control unit controls the take-up motor to drive the take-up slider to slide the clamping assembly 321 along the second direction b after the fabric is cut, so that the slide can stop at a designated location and the fabric can be released.
