Description

Technical Field

[0001] This utility model relates to the field of textile equipment, specifically to a device for splicing webbing / round rope / strips. Background Technology

[0002] Webbing (including but not limited to round, flat, or other shapes) is typically used to sew carpets / mats, and is generally sewn by hand. In the process of hand-sewing large carpets, the process begins with taking a portion from a whole roll / whole strip of webbing, such as... Figure 1 The process involves cutting out the first webbing 201, then sewing the second webbing 202 alongside it using a sewing machine. When the lengths are roughly equal, the second webbing is cut into sections. The third webbing is then sewn alongside the second webbing, and so on, until a long strip of board-shaped fabric 200 with a width of about 10 centimeters (depending on the space of the sewing machine, with a maximum width of 40cm) is formed. (Due to limited manpower and the weight of the webbing itself, it is necessary to drag the sewn webbing back and forth each time it is sewn, which is not conducive to manual operation even if it is wide.) Multiple long strips of board-shaped fabric are then sewn in this way, and then the multiple long strips of board-shaped fabric are spliced ​​together to form a carpet that is wide enough. It is difficult to ensure that the length of each webbing cut is consistent each time, because there are different lengths. The entire carpet still needs to be cut again after it is formed. The whole process is time-consuming and laborious, and causes a lot of material waste.

[0003] There is an urgent need to invent a new device to save manpower and resources. Summary of the Invention

[0004] The purpose of this invention is to provide a device for splicing webbing, which can splice webbing and save manpower and resources.

[0005] A device for splicing webbing, characterized in that it comprises: a support base, a first transmission column, a second transmission column, a limiting part, a sewing machine, a power unit, and a controller. The first and second transmission columns are disposed on the support base, and the positions of the first and / or second transmission columns relative to the support base are adjustable. The first and / or second transmission columns are connected to the power unit. The webbing is located inside the limiting part, which abuts against the webbing to move it inward. The controller is electrically connected to the power unit and the sewing machine. When the webbing is wound around the first and second transmission columns, the controller can control the operation of the power unit to drive the first and / or second transmission columns to rotate, and synchronously control the operation of the sewing machine, enabling the splicing of adjacent webbing.

[0006] By adopting the above technical solution, the power component can drive the connected transmission columns to rotate, causing the webbing to rotate continuously. This allows the fed webbing to continuously wrap around each transmission column. The limiting part prevents the webbing from moving outward, instead causing the webbing to move along the other side (inner side) of the transmission column's length direction. The fed webbing can then be sewn together with adjacent webbing using a sewing machine to form a large looped fabric. Finally, a large carpet / mat can be formed by manual or machine cutting. The position of the first and / or second transmission columns relative to the support base is adjustable, allowing control over the size of the spliced ​​webbing, adjusting the size of the sewn carpet or mat, and further expanding the size of the splicable webbing.

[0007] As a further improvement of this utility model, the limiting part is provided on the first transmission column and / or the second transmission column, the outer edge surface of the limiting part protruding from the outer edge surface of the first transmission column and / or the second transmission column, and the limiting part is located near the end of the first transmission column and / or the second transmission column. By adopting the above technical solution, the spliced ​​webbing can be moved inward along the length direction of the transmission column to cover the entire transmission column and form a large fabric with a wider width.

[0008] As a further improvement of this utility model, the limiting part is annular. By adopting the above technical solution, the annular limiting part is installed on the corresponding transmission column and rotates with the rotation of the transmission column, which facilitates the limiting of the webbing and causes the webbing to move away from the limiting part.

[0009] As a further improvement of this utility model, the limiting part is composed of two semi-circular ring components spliced ​​together; friction parts are provided on the first transmission column and / or the second transmission column. By adopting the above technical solution, the two semi-circular ring components constitute the limiting part, which is convenient for disassembly, assembly, and fixation. The friction parts can improve the conveying efficiency of the webbing.

[0010] As a further improvement of this utility model, the limiting part is located between the first transmission column and the second transmission column, and the position of the limiting part for abutting the webbing is within the end position of the first transmission column and / or the second transmission column. By adopting the above technical solution, this position setting of the limiting part can also limit and abut the webbing, allowing the webbing to move inward along the length direction of the transmission column.

[0011] As a further improvement of this utility model, the first and second transmission columns are horizontally arranged, and their rotation center lines are parallel. The rotation center lines of the first and second transmission columns are located in the same transverse plane, the same longitudinal plane, or the same oblique plane. During sewing, the outer surfaces of the first and second transmission columns are on the same plane as the sewing machine's needle plate and presser foot. By adopting the above technical solution, the specific arrangement of the two transmission columns facilitates the smooth movement of the webbing. The fact that the outer surfaces of the first and second transmission columns are on the same plane as the sewing machine's needle plate and presser foot allows the webbing to be fed straight, facilitating sewing and splicing.

[0012] As a further improvement of this utility model, it also includes a reversing device, a shearing device, a conveying device, a tensioning device, and a tape-guiding device for preventing the webbing from knotting. The controller is connected to the reversing device and can control the power component to rotate in the opposite direction. The shearing device is located between the two transmission columns. The conveying device, tensioning device, and tape-guiding device are located around the first transmission column, on the feed line of the sewing machine. The conveying device includes a driving wheel and a driven wheel, the ends of which are meshed by gears. The webbing is wound around the driving wheel and the driven wheel in a figure-eight shape. The tensioning device includes a tensioning roller and several tensioning wheels. The relative position of the tensioning roller and the tensioning wheels is adjustable. A roller is also provided on the outer surface of the webbing to press it onto the webbing. By adopting the above technical solution, the reversing device is mainly used for situations such as thread breakage, skipped stitches, and missed stitches during sewing. The reversing device allows the broken thread, skipped stitch, or missed stitch to return to the sewing machine needle for continued sewing. The shearing device can cut the webbing along its width after splicing to form carpets or mats. The installation of conveying, tensioning, and webbing management devices facilitates the conveying, tensioning, and knot prevention of the webbing, making subsequent sewing easier. Combined with a controller, it enables unmanned, automated splicing and sewing, improving the overall automation of the system. One person can manage multiple machines, achieving automated operation and significantly improving work efficiency. Because some sewing materials are too stiff and do not easily adhere well to the drive column, to increase the friction and adhesion between the carpet and the drive column, ensuring smooth forward movement, rollers (pressure rollers) can be added to the outer surface of the webbing (this can be the outer surface of the webbing above the sewing machine, above or below the first drive column, or above or below the second drive column). These rollers compress the sewing material, ensuring synchronous movement with the drive column and preventing slippage.

[0013] Compared with the prior art, the beneficial effects of this utility model are at least as follows: using the device involved in this utility model to splice webbing saves manpower and material resources, and can form large carpets / mats, which is convenient for promotion and application. Production efficiency and application prospects are significantly improved, realizing unmanned automation and one person managing multiple devices. It is a major innovation in the splicing of webbing carpets and mats.

Example

[0033] It should be noted that the webbing involved in this utility model includes, but is not limited to, the three-layer core-spun webbing, round rope webbing, flat webbing or other shaped webbing or strips made of cloth, as involved in patent number 2019209175090.

[0034] See Figures 2-8 A device for splicing webbing includes: a support base, a first drive column 1, a second drive column 5, a limiting part 6, a sewing machine 8, a power unit, and a controller. The first drive column 1 and the second drive column 5 are mounted on the support base. The two drive columns can have the same diameter. The position of the first drive column 1 and / or the second drive column 5 relative to the support base is adjustable (e.g., it can be slidably mounted along a track on the support base). The first drive column 1 and / or the second drive column 5 are connected to the power unit. The webbing is located inside the limiting part 6, which abuts against the webbing to move it inward. The limiting part 6 is provided on the first drive column 1 and / or the second drive column 5, and the outer edge surface of the limiting part 6 protrudes beyond the outer edge surface of the drive column on which it is mounted (e.g., it can be slidably mounted along a track on the support base). Figure 5 As shown, the limiting part 6 is disposed on the second transmission column 5, and the outer edge surface of the limiting part is higher than the outer edge surface of the second transmission column. When the limiting part is disposed on the first transmission column, the outer edge surface of the limiting part is higher than the outer edge surface of the first transmission column. The controller is electrically connected to the power unit and the sewing machine 8. When the webbing is wrapped around the first transmission column 1 and the second transmission column 5, the controller can control the operation of the power unit, drive the first transmission column 1 and / or the second transmission column 5 to rotate, and synchronously control the operation of the sewing machine 8. The sewing machine 8 can splice adjacent webbing. The side of the webbing wrapped around the two transmission columns is in the shape of a racetrack.

[0035] Specifically, the power component can be an electric motor, such as the rotating shaft of the first transmission column 1 being connected to the first motor 2, and the rotating shaft of the second transmission column 5 being connected to the second motor 4. In other embodiments, the first transmission column may be connected to a motor while the second transmission column is not equipped with a motor, or the first transmission column may not be connected to a motor while the second transmission column is connected to a motor.

[0036] In other designs, the motor can also be installed at one or both ends inside the corresponding drive column.

[0037] like Figure 3 , Figure 5 , Figure 7 The limiting part 6 is disposed on the second transmission column 5. In other embodiments, the limiting part may be disposed on the first transmission column, or as shown below. Figure 8 As shown, a limiting part 6 is provided on both the first transmission column and the second transmission column.

[0038] The first transmission column 1 and the second transmission column 5 can be directly or indirectly mounted on the support base. The support base can be a symmetrically arranged frame. For example, if the first transmission column 1 and the second transmission column 5 are arranged longitudinally, the support base can be a first support frame 3 and a second support frame 7 arranged laterally (each frame is assembled from profiles). One end of the first transmission column 1 and the second transmission column 5 spans across the first support frame 3, and the other end spans across the second support frame 7. Of course, in other embodiments, the number of transmission columns can be more than two as needed.

[0039] Guide rails, slides, etc., can be provided on the support base to allow for position adjustment of the first drive column 1 and / or the second drive column 5. In one embodiment, the position of the first drive column 1 relative to the support base can be relatively fixed, while the position of the second drive column 5 can be slidably adjusted relative to the support base to accommodate carpets of different sizes. For details, please refer to [reference needed]. Figure 5 For example, a guide rail is provided on the second support frame 7, and a slide block 16 is provided on the guide rail. The slide block 16 can move relative to the guide rail to adjust the position of the object on it. A base plate 15 is provided on the slide block 16, a support rod 14 is provided on the base plate 15, a support plate is provided on the support rod 14, and a bearing seat 13 is provided on the support plate. The rotating shaft of one end of the second transmission column 5 is connected to the bearing seat 13 through a bearing. On the other side, a guide rail and a slide block are provided on the first support frame 3, and a base plate is provided on the slide block. A second motor 4 is directly or indirectly provided on the base plate, and the rotating shaft of the other end of the second transmission column 5 is connected to the output shaft of the second motor 4. A locking handle 17 can be provided on the base plate 15 to lock the position of the base plate relative to the guide rail. One end of the first transmission column 1 is provided on the support base through a bearing, bearing seat, etc., and the other end is connected to the output shaft of the first motor 2. The first motor is mounted on the support base. In other embodiments, each transmission column can also be configured to be electrically adjustable to control the size of the carpet.

[0040] Support rollers 10 can also be installed on the support base to support the webbing. For example, a roughly inverted T-shaped support frame 11 can be installed on the guide rails of the first support frame 3 and the second support frame 7. The support frame 11 is connected to the guide rails via a slide. A locking handle can be installed next to the slide and below the support frame to lock the position of the support frame and fix it to the guide rails. Two support grooves are opened on the support frame along the vertical direction to install two support rollers 10. The two support rollers 10 support the lower part of the circular carpet respectively. The sewing machine 8 can be installed on the sewing machine base frame 9. A crossbeam is installed at the bottom of the sewing machine base frame 9. One end of the crossbeam is connected to the vertical beam on the side, and the other end extends inward along the length of the transmission column. This crossbeam serves as a support and also allows the bottom of the sewing machine and the bottom of the transmission column to be an open structure, ensuring that the carpet does not pass through when sewing. The number of support frames and support rollers can be set multiple times according to needs to support webbing of different weights, preventing the webbing from sagging due to its own weight, affecting splicing, and making it less prone to deformation or dimensional changes during sewing. Simultaneously, rollers 12 (pressure rollers) can be added to the outer surface of the webbing (here, the outer surface of the webbing can be the surface above the webbing below the sewing machine, or the outer surface of the webbing above or below the first drive column, or the outer surface of the webbing above or below the second drive column) to press the webbing onto it, facilitating tension and smooth movement of the webbing during sewing. That is, the position of the rollers 12 can be adjusted as needed, as long as it can press the webbing firmly onto the surface of the corresponding drive column, facilitating webbing tension and movement. The limiting part 6 is provided on the first drive column 1 and / or the second drive column 5. The outer edge surface of the limiting part 6 protrudes from the outer edge surface of the first drive column and / or the second drive column, and the limiting part 6 is located near the end of the first drive column 1 and / or the second drive column 5, with the webbing located inside the limiting part 6. See reference. Figure 3 and Figure 5 The inner side refers to the side closer to the center of the transmission column. The limiting part 6 is annular. The limiting part 6 can be a protruding annular component, which can be integrally formed with the transmission column, or it can be a single piece of annular component with holes. During installation, it is fitted onto the surface of the transmission column, and a fastening screw is provided on the annular component.

[0041] Preferably, the limiting part is composed of two semi-circular ring components spliced ​​together, and the two semi-circular ring components are detachably connected to the first drive column and / or the second drive column 5 by fasteners such as bolts. The first drive column and / or the second drive column are provided with friction parts, which can be oriented rubber granules or attachments with threads or recesses, allowing the spliced ​​floor mat to move more smoothly to the end away from the sewing machine (i.e., move inward to each drive column).

[0042] In other embodiments, the limiting portion may be protrusions arranged in a circumferential array and disposed on the surface of the corresponding transmission column.

[0043] The device for splicing webbing also includes a reversing mechanism. A controller connected to the reversing mechanism can control the power unit to rotate in the reverse direction, thereby causing each drive column to rotate in the reverse direction. This prevents thread breakage or the absence of bobbin thread during sewing. If over-sewing is detected, the reversing controller can control the drive shaft to move in the reverse direction, returning the broken thread section to a position where sewing and splicing can continue. It is mainly used for situations such as thread breakage, skipped stitches, and missed stitches during sewing. The reversing mechanism allows the broken thread, skipped stitch, or missed stitch section to return to the sewing machine's needle position for continued sewing.

[0044] See Figure 4 , 5 6. The first transmission column 1 and the second transmission column 5 are arranged horizontally. The rotation center lines of the first transmission column 1 and the second transmission column 5 are parallel.

[0045] The rotation center lines of the first transmission column 1 and the second transmission column 5 are located in the same transverse plane, the same longitudinal plane, or the same oblique plane. For example... Figure 6 , 7 8. The rotation center lines of the first transmission column 1 and the second transmission column 5 are located in the same transverse plane. In other embodiments, the rotation center lines of the two transmission columns may be located in the same longitudinal plane or the same oblique plane. During sewing, the outer surfaces of the first transmission column 1 and the second transmission column 5 (the outer surfaces of the first transmission column 1 and the second transmission column 5 can be as follows) Figure 7 , Figure 8 The outer surface formed by the upper outer edge generatrix of the two drive columns is on the same plane as the needle plate and presser foot of the sewing machine.

[0046] In other embodiments, such as Figure 12 The limiting part 6 can be cylindrical (in other embodiments, the cross-section of the limiting part can be polygonal, etc.), and can be installed on the ground or on a support base. The limiting part is located between the first transmission column and the second transmission column, and the position of the limiting part 6 that abuts against the webbing is within the end position 51 of the first transmission column and / or the second transmission column.

[0047] See Figure 9 , Figure 10 and Figure 11The device for splicing webbing also includes a cutting device, a conveying device, a tensioning device, and a webbing straightening device to prevent the webbing from knotting. The cutting device is located between two transmission columns and is used to cut the spliced ​​webbing. The cutting device is existing technology and can be a fabric cutting machine, including but not limited to the bidirectional fabric cutting machine described in 202323120598.1. The specific structure will not be described in detail. The conveying device, tensioning device, and belt feeding device are located around the first transmission column, on the feed line of the sewing machine (in the direction of the webbing feed). The conveying device includes a driving wheel 31 and a driven wheel 33. The ends of the driving wheel and the driven wheel mesh with gears 32. Multiple gears 32 can be provided. The surfaces of the driving wheel and the driven wheel have several recesses 311 for winding the webbing. One end of the webbing is wound into the driven wheel, then wound in a figure-eight shape around the driving wheel and the driven wheel, and then exits from the driving wheel. The end of the driven wheel 33 is connected to a guide pressure wheel 331 via two connecting rods 332 (one end of one connecting rod is connected to the driven wheel). One end is connected to another connecting rod, and the other end of the other connecting rod is connected to a guide pressing wheel. The two connections are tightened by a spring 333. When the webbing is trapped in the recess on the surface of the driven wheel, the guide pressing wheel 331 presses and guides the webbing. The tensioning device includes a tensioning roller 22 and several tensioning wheels 21. The relative positions of the tensioning roller and tensioning wheels can be adjusted up and down. An adjustment groove 23 is opened on the base of the tensioning device. The tensioning roller 22 is mounted on the adjustment groove 23 through a connecting plate. The tensioning wheel can also be adjusted up and down relative to the corresponding adjustment groove. Several tensioning wheels 21 are arranged side by side. The webbing 101 is wound in an S-shape around the adjacent tensioning wheel and comes out from the tensioning roller 22. When the tensioning device is arranged, the tensioning wheel is close to the side of the sewing machine presser foot, the tensioning roller is close to the side of the conveying device, and the other side of the conveying device is close to the belt feeding device. The tensioning device, conveying device, belt feeding device, sewing machine presser foot and needle can be arranged in a straight line.

[0048] Near the presser foot and needle plate of the sewing machine (in the direction of the webbing feed), a webbing tensioning device, a synchronous webbing conveyor, and a webbing guide device are installed. The webbing guide device can organize the webbing rollers, which can improve the automation level of the entire device. The operator only needs to change the bottom thread and top thread of the sewing machine and the webbing feed. One person can operate multiple machines at the same time, which greatly improves work efficiency and the mass production of products.

[0049] The tensioning device can be adjusted up and down to control the tension of the carpet webbing and the tightness of the sewn products. The conveying device delivers the webbing to the tensioning device without resistance. The webbing guide device is existing technology, which mainly includes a polygonal-shaped guide roller 41 with baffles 42 on both sides. The guide roller 41 is rotatably mounted on a support 44, and both ends of the guide roller can be directly or indirectly connected to a motor. Figure 11The diagram shows that one end of the straightening roller 41 is connected to the motor via a pulley 43. The webbing straightening device is used to straighten the webbing. Sometimes the webbing gets tangled or knotted. The straightening roller 41 of the straightening device rotates in the opposite direction to the conveying direction of the webbing 101, and its reverse rotation can be used to beat the webbing, thereby straightening it. After being straightened by the straightening device, the webbing is transported to the conveying device, and then to the tensioning device. Finally, it is sent to the first drive column, sewing machine, and other positions to facilitate continuous sewing by the sewing machine.

[0050] In use, after the webbing 101 is unloaded, it wraps around the first drive column 1 and the second drive column 5. The webbing is positioned inside the limiting part 6, and the part to be joined is located below the sewing machine head 8. The controller is activated, and the two motors are controlled to rotate synchronously in the same direction, thereby driving the first drive column 1 and the second drive column 5 to rotate in sync with the sewing machine. Figure 7 From the perspective shown, the rotation direction of the two drive columns can be clockwise. The webbing moves from the first drive column to the second drive column. The controller can control the sewing machine needle to synchronously sew adjacent webbing that needs to be joined. As the webbing is fed, it abuts against the limiting part 6. The limiting part 6 prevents the webbing from moving outward from each drive column while causing the webbing to move inward from each drive column. Following the rotation of each drive column and cooperating with the sewing machine, adjacent webbing are joined together to form a large loop fabric 100 that extends continuously along the length of each drive column. When the predetermined size of the carpet is reached, or when the maximum length of the drive column is reached, the sewing can be stopped and the rotation of each drive column can be stopped. Subsequently, the loop fabric can be cut manually or using a cutting device to unfold it into a large rectangular carpet.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
