Description

Technical Field

[0001] The invention relates to the field of flat knitting machines, in particular to an automatic rubber band tying device for knitted fabrics. Background Art

[0002] The computerized glove knitting machine is a double-needle plate latch needle weft knitting machine. Its cam mechanism acts like a set of flat cams. The needle's foot enters the cam's groove, moving the cam, forcing the needle to perform a regular up-and-down motion within the needle groove of the needle plate. Through the action of the needle hook and the needle latch, the yarn can be woven into a knitted fabric. As the needle rises, the yarn gradually exits the hook, opening the needle latch and withdrawing it to hang on the needle bar. As the needle descends, the hook grabs the newly placed yarn and pulls it into a coil, while the existing coil escapes the hook. The new coil passes through the old coil and is connected in series with the old coil. Numerous strings of knitted yarns are connected to form a knitted fabric.

[0003] After the knitted fabric is formed between the double needle plates, it falls down. Through an automatic finishing device such as that disclosed in CN202111320479.3, the knitted fabric can be neatly moved to the platform or conveyor belt outside the computer flat knitting machine, and then the neatly stacked knitted fabric can be automatically bundled through an automatic bundling device.

[0004] The above-mentioned automatic sorting and bundling devices have only appeared in this field in the past two years and are still imperfect. Zhejiang Baixiang Technology Co., Ltd. disclosed an automatic glove bundling machine in "202122521567.1", which includes a rubber band receiving and bundling device, a rubber band placing device, and a glove pushing device. However, this solution has the following disadvantages:

[0005] First, the rubber band placing device cannot handle bundles of rubber bands: when a bundle of rubber bands is put on a single roller, the rubber bands are stacked in an interlaced state, which is not conducive to the hooking of the hook line assembly; if the rubber bands are manually sorted and then put on the roller, it is actually equivalent to manually tying the stacked gloves, which does not improve production efficiency.

[0006] Secondly, the hook heads of all hook wire components in the rubber band receiving and bundling device need to be accurately positioned on the radial slots on the drum. Due to the rotation of the drum itself, it is also necessary to ensure that the radial slots stay in the same position each time after rotation to ensure that each hook head can hook the rubber band ring; at the same time, the hook wire component is divided into a hook wire strip and a release strip, which has a complex structure, and the spring pressure piece bears all the force. Its own properties make it easy to cause metal fatigue and lose elasticity, and it is possible to fall off from the hook wire strip and the release strip; the hook head of the hook wire strip needs to ensure that the rubber band ring does not fall off when hooking the wire, and it also needs to ensure that it does not cause excessive resistance when falling off, so that the release strip cannot let the rubber band ring fall off.

[0007] Finally, in the glove pushing device, the glove is pushed by the push plate, which easily causes the finger portion of the glove to bend, and according to the disclosed solution, only one end of the glove can be tied.

[0008] Therefore, the inventor conducted further research on this and developed a knitted fabric automatic rubber band tying device, which resulted in the present invention. Summary of the Invention

[0009] The object of the present invention is to provide a knitted fabric automatic rubber band tying device that can overcome the problems existing in the above-mentioned prior art.

[0010] In order to achieve the above object, the technical solution of the present invention is as follows:

[0011] An automatic rubber band tying device for knitted fabrics, comprising

[0012] The rubber band conveying device includes two horizontal rollers with spiral grooves;

[0013] The rubber band binding device includes four rubber band claws, which move on the same base. The rubber band claws include fixed claws and movable claws, and the movable claws can move relative to the fixed claws;

[0014] A rotating placement platform is provided on one side of the rubber band binding device, and the rotating placement platform adjusts the binding position of the knitted fabric by rotating itself;

[0015] The rubber band conveying device has the function of moving toward the rubber band bundling device, and the rubber band bundling device has the function of moving toward the rotating placement platform. The bundles of rubber bands are allowed to enter the spiral groove and be separated from each other through the rotation of the roller. The separated rubber bands are conveyed to the rubber band claws of the rubber band bundling device through the movement of the rubber band conveying device. The four rubber band claws are gathered and expanded through movement. The fixed claw of the rubber band claw is used to grab the rubber band, and the movable claw can push the rubber band from the end of the fixed claw by moving relative to the fixed claw, thereby bundling the knitted fabric placed on the rotating placement platform.

[0016] Compared with the prior art, the above scheme has the problem of rubber band conveying as described in the background. However, the present invention provides two rollers so that the rubber band claws can be removed by expanding from between the two rollers, which allows a certain amount of motion error in the operation of the device.

[0017] In the rubber band bundling, the "four-claw" expansion method is adopted. However, compared with the prior art, the fixed claw of the present invention is rigid and will not be affected by the tightening force of the rubber band. The rubber band is pushed out from the end of the fixed claw by the movable claw, which can avoid the problems described in the background art.

[0018] On the placement platform, by setting a rotating placement platform, the knitted fabric itself has the ability to adjust its own placement angle, and the two ends of the same knitted fabric can be tied;

[0019] Through the cooperation between the above mechanisms, an automatic sorting effect is achieved.

[0020] Furthermore, the four rubber band claws of the rubber band binding device are driven by the same binding drive mechanism.

[0021] Driving the rubber band grabber through the same driving mechanism can improve its synchronization rate and simplify the overall structure of the device.

[0022] Furthermore, the strapping drive mechanism includes a gear driven to rotate by a motor, the gear is linked to a plurality of racks, and the racks are linked to respective rubber band claws.

[0023] Furthermore, a boss is provided on the base, a fixed claw of the rubber band claw is provided on a sliding seat, and the sliding seat moves on the base; a limiting groove for accommodating the rubber band is provided at the end of the fixed claw, the movable claw and the fixed claw are arranged in parallel, and the movable claw and the fixed claw are connected by a reset spring;

[0024] When the rubber band claw moves to the boss, one end of the movable claw slides onto the boss and moves relative to the fixed claw, and the other end of the movable claw pushes the rubber band out of the limit groove; when the movable claw slides out of the boss, the reset spring returns the movable claw to its original position.

[0025] The boss is located at the position where the rubber band detaches after expansion, and is generally located around the base.

[0026] Furthermore, a strip groove is provided on the movable claw, and an adjusting bolt is provided in the strip groove. The adjusting bolt restricts the movable claw to one side relative to the fixed claw.

[0027] The adjusting bolt cannot tighten the movable claw and can be replaced by other parts with similar limiting functions.

[0028] Furthermore, the rotating placement platform includes a main bearing plate and a bearing telescopic plate, and the bearing telescopic plate can extend or retract relative to both sides of the main bearing plate.

[0029] Taking knitted gloves as an example, in order to bundle stacked gloves, the bottom of the gloves should be suspended in the air. Once the gloves are suspended in the air, they are likely to sag or fall. Therefore, a supporting telescopic plate is needed to support one end of the gloves. After the supporting telescopic plate and gloves are tied together with rubber bands, the supporting telescopic plate can be retracted. If the other end of the gloves needs to be bundled, the main supporting plate is rotated 180 degrees and the above steps are repeated.

[0030] Furthermore, the rotation of the main bearing plate is achieved through a gear set, and the bearing telescopic plate slides in the arc groove through the linked rollers, thereby pushing the bearing telescopic plate to perform telescopic movement relative to the main bearing plate.

[0031] Furthermore, the side edges of the main bearing plate are provided with arc-shaped folded edges.

[0032] The curved hem can better define the knitted fabric.

[0033] Furthermore, a lifting and pressing plate is provided on the side of the rotating placement platform, and the lifting and pressing plate compacts the fluffy fabric by pressing downward.

[0034] The lifting plate is used to assist in bundling the stacked knitted fabrics.

[0035] Furthermore, the two rollers of the rubber band conveying device are driven to rotate by the same motor through a synchronous belt.

[0036] After adopting the above scheme, the present invention has the following advantages compared with the prior art:

[0037] 1. The rubber band conveying device ensures that the rubber bands will not be entangled or twisted. The continuous spiral groove of the roller can separate the bundled elastic rings one by one, and it is more convenient to grab the rubber bands from between the two rollers;

[0038] 2. The rubber band binding device ensures that the rubber band claw has sufficient rigidity and stability, and is not affected even when the rubber band is expanded sufficiently;

[0039] 3. The platform for receiving and fixing the fabric is flexible. BRIEF DESCRIPTION OF THE DRAWINGS

[0069] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0070] An automatic rubber band tying device for knitted fabrics includes a rubber band conveying device 1, a rubber band bundling device 2, and a rotating placement platform 3. The device is described by taking the rubber band tying device 6 in conjunction with a glove knitting machine 4 (a flat knitting machine specially used for knitting gloves) as an example. Figure 1 shown.

[0071] The rubber band conveying device 1 can be arranged on the side wall of the glove machine 4. The specific structure is as follows: Figure 2 、 Figure 3 As shown, the first drive motor 11 drives the first drive gear 12 to rotate, and the first drive gear 12 drives the first drive rack 13 to translate; the rubber band conveying device 1 is connected to a group of first slide rails 14 and the first drive rack 13 through the base plate 15 to achieve translation.

[0072] Two horizontal rollers 16 are mounted on the bottom plate 15 of the rubber band conveyor 1. These rollers 16 are provided with continuous spiral grooves whose dimensions match those of a single rubber band loop. The two rollers 16 are driven by a timing belt 17, which is driven by another independent drive unit. After a bundle of rubber bands 5 is wound around the two rollers 16, the rollers 16 are rotated to gradually embed the rubber bands into the spiral grooves, achieving separation.

[0073] The rubber band binding device 2 is arranged on one side of the glove machine 4 and the rubber band conveying device 1. The specific structure is as follows: Figure 4-7 As shown, it includes a relatively vertically arranged base 21, four spaced-apart slide grooves 212 are provided on the base 21, and a rubber band claw is provided on each slide groove 212. The sliding seat 23 of the rubber band claw is linked to the bundling transmission structure 22 on the back of the base 21, and a fixed claw 24 perpendicular to the base 21 is provided on the sliding seat 23. A movable claw 25 is provided on one side of the fixed claw 24, and an L-shaped limiting groove 241 is provided at the end of the fixed claw 24, so that the four fixed claws 24 can grab the rubber band by expansion, and the movable claw can push the rubber band out of the limiting groove 241 of the fixed claw 24 by movement.

[0074] like Figure 7 As shown, the movable claw 25 is provided with a strip groove, in which an adjusting bolt 251 is disposed. The adjusting bolt 251 constrains the movable claw 25 to one side relative to the fixed claw 24. At the same time, the movable claw 25 and the fixed claw 24 are connected by a return spring 26. In the figure, one end of the return spring 26 is fixed to the fixed claw 24, and the other end is not yet engaged with the corresponding hanging hole of the movable claw 25. According to actual conditions, by adjusting the preload of the adjusting bolt 251 and the tension of the return spring 26, the movable claw 25 can be pushed and reset by the return spring 26.

[0075] The pushing of the movable claw 25 is achieved by setting a boss 211 on the base 21. The boss 211 is set on one side of the slide groove 212, and the boss 211 is set on the movement path of the rubber band claw. When the rubber band claw expands the rubber band and the rubber band needs to be detached, the bottom end of the movable claw 25 needs to slide onto the boss 211, and then under the action of the boss 211, the movable claw 25 is lifted relative to the fixed claw 24, thereby pushing out the rubber band in the limiting groove 241; and when the movable claw 25 slides down from the boss 211, it returns to its position under the action of the reset spring 26.

[0076] like Figure 6 As shown, the bundling transmission structure 22 is driven by a second driving motor 221 , and the second driving motor 221 drives four second driving racks 222 to move synchronously through a gear set, and each second driving rack 222 corresponds to a rubber band claw.

[0077] The entire rubber band binding device 2 is on the second slide rail 27 and can move along the second slide rail 27 , and its movement direction is perpendicular to the movement direction of the rubber band conveying device 1 .

[0078] The rotating placement platform 3 is arranged above one end of the second slide rail 27, and mainly includes a main bearing plate 31 and a bearing telescopic plate 32. Figure 8 As shown, the supporting telescopic plate 32 can extend or retract relative to both sides of the main supporting plate 31 .

[0079] In order to bundle the stacked gloves 6, the bottom of the gloves should be suspended. Once the gloves are suspended, they are likely to sag or fall. Therefore, one end of the gloves needs to be supported by a supporting telescopic plate 32. After the supporting telescopic plate 32 and the gloves are tied together with the rubber band, the supporting telescopic plate 32 can be retracted. If the other end of the gloves needs to be tied, the main supporting plate 31 can be rotated 180 degrees.

[0080] The rotation of the main bearing plate 31 is realized by a gear set. Figure 9-12 The small and medium gears are driving gears, which are linked to the motor, and the large gear is the driven gear, which is linked to the main bearing plate 31.

[0081] The expansion and contraction of the supporting expansion plate 32 is achieved through the following hierarchical structure:

[0082] Below the main bearing plate 31 is the bearing telescopic plate 32, below the bearing telescopic plate 32 is the connecting seat 312, below the connecting seat 312 is a half cam and an arc plate, an arc groove 323 is formed between the half cam and the arc plate, and a roller 321 is provided on the same plane as the arc groove 323. The roller 321 is linked to the bearing telescopic plate 32 through a connecting frame 322. The above linkage method requires a groove to be opened on the connecting seat 312.

[0083] by Figures 9-12 For reference:

[0084] Figure 9 , is the initial state of waiting to place the gloves, that is Figure 1 The initial state of the rotating placement platform 3.

[0085] Figure 10 , is the state when the main bearing plate 31 rotates 90 degrees to tie the rubber band to one end of the glove for the first time, and at this time the roller 321 is not restricted by the arc groove 323.

[0086] Figure 11 exist Figure 10 On the basis of this, the main bearing plate 31 rotates 180 degrees again. At this time, since the roller 321 is restricted, the connecting frame 322 pushes the bearing telescopic plate 32 to move from the right side to the left side, and lifts the other end of the glove that needs to be tied.

[0087] Figure 12 After tying the two ends of the gloves, Figure 11 The state of the whole device is rotated 180 degrees again, and the supporting telescopic plate 32 is again separated from the rubber band. Figure 13 .

[0088] by Figure 10-11 For example, when the main bearing plate 31 and the connecting seat 312 rotate 180 degrees, the roller 321 also rotates from the left to the right. Since the roller 321 begins to be restricted by the arc groove 323 after rotating 90 degrees, the push-bearing telescopic plate 32 linked with the roller 321 is pushed to the left. Figure 11 In the figure, the main bearing plate 31, the connecting seat 312, and the roller 321 are relative to each other. Figure 10 In fact, it rotates 180 degrees, but because the roller 321 is restricted by the arc groove 323, the supporting telescopic plate 32 that should be on the right side is actually pushed to the left side, realizing the telescopic function.

[0089] The main support plate 31 is equipped with a curved hem 311 on its side, which, in this embodiment, better secures the gloves in place. A lifting and pressing plate 33 is also installed on the side of the rotating platform 3. This plate compacts the loose gloves by pressing downward, assisting in bundling the stacked gloves. Driven by an independent motor, the lifting and pressing plate 33 can be positioned on the side of the rotating platform 3, as long as the pressing portion of the lifting and pressing plate 33 is positioned above the gloves.

[0090] The working process of this device is as follows:

[0091] The rubber band conveying device 1 has the function of moving toward the rubber band bundling device 2 through the cooperation of the first drive motor 11, the first drive gear 12, the first drive rack 13, and the first slide rail 14, and the rubber band bundling device 2 can also move toward the rotating placement platform 3 along the direction of the second slide rail 27.

[0092] The rubber band conveying device 1 rotates the two rollers 16 to make the bundled rubber bands enter the spiral groove to separate from each other. The separated rubber bands are conveyed to the rubber band claws of the rubber band bundling device 2 by the movement of the rubber band conveying device 1. The four rubber band claws are in a gathered state, such as Figure 14 shown.

[0093] Subsequently, the four rubber claws are pushed into the rubber ring, so that the limiting groove 241 of the fixed claw 24 of the rubber claw matches the rubber, and then the rubber claw expands outward, the rubber conveying device 1 moves backward, the rubber conveying device 1 returns to its position, and the rotating placement platform 3 drives the gloves to rotate 90 degrees clockwise. The lifting and pressing plate 33 first presses down to compact the fluffy gloves and then rises to leave space for the rubber to enter. The fixed claw 24 of the rubber claw moves forward with the rubber to enter the bundling position. Figure 15 shown.

[0094] like Figure 16 As shown, the rubber band claw continues to move outward. At this time, the movable claw 25 of the rubber band claw is acted upon by the inclined surface of the boss 211, thereby pushing the rubber band out of the limiting groove 241 of the fixed claw 24, so that it is tied to the glove (at this time, the lower part of the rubber band is tied together with the supporting telescopic plate 32).

[0095] The rotating placement platform 3 rotates 180° clockwise, and the supporting telescopic plate 32 retracts and moves to the opposite side to lift the other end of the glove waiting to be tied (that is, the aforementioned Figure 10-11 The lifting plate 33 first presses down to compact the fluffy gloves and then rises to leave space for the rubber band to enter, and the rubber band claws with the rubber band move forward to the bundling position.

[0096] Repeat the above steps to tie the other side of the glove. Figure 12 、 Figure 13 Finally, the gloves can slide along the slope on the right into the storage box where the gloves are placed.

[0097] The above are only specific embodiments of the present invention. At the same time, all words such as "upper, lower, left, right, middle" involved in the present invention are for reference only and are not absolute limitations. Any non-substantial changes made using the present invention shall be deemed as an infringement of the protection scope of the present invention.
