Description

A technique for automatically binding rubber bands to gloves

technical field

The invention relates to the field of horizontal knitting machines, in particular to a technique for automatically binding rubber bands on gloves.

Background technique

Computer glove machine is a weft knitting machine with double-needle plate and latch needle. Its cam device is like a set of flat cams. The regular lifting movement, and through the action of the needle hook and the needle latch, the yarn can be woven into a knitted fabric. When the knitting needle is rising, the coil gradually withdraws from the needle hook, opens the needle latch, and withdraws from the needle latch to hang on the needle bar; while the knitting needle is falling, the needle hook catches the newly placed yarn and pulls it Bending into coils, while the original coils come out of the needle hook, new coils pass through the old coils, and are connected in series with the old coils, and many knitted coil strings are connected to each other to form a knitted fabric.

After the knitted fabric is formed between the double needle plates, it falls, and the knitted fabric can be neatly moved to the platform or conveyor belt outside the computerized flat knitting machine through an automatic finishing device such as that disclosed in CN202111320479.3, and then automatically tied The device automatically binds neatly stacked knitted fabrics.

The above-mentioned automatic finishing device and strapping device have only appeared in this field in the past two years, and they are still incomplete. Among them, Zhejiang Baixiang Technology Co., Ltd. disclosed an automatic strapping machine for gloves in "202122521567.1", including rubber band connection and strapping device, elastic device and glove device, but there are following disadvantages in this program:

First of all, the device for placing elastic bands cannot realize the processing of bundles of elastic rings: when a bundle of elastic rings is set on a single drum, the elastic rings are stacked in a staggered state, which is not conducive to the hooking of the hook line components; Putting the elastic rings on the roller after sorting them is actually equivalent to manually binding the stacked gloves, which cannot improve production efficiency.

Secondly, the hook heads of all hook wire components in the rubber band and binding device need to accurately position the radial groove on the drum. Due to the rotation of the drum itself, it is also necessary to ensure that the radial groove stays at the same position each time after rotation. position, to ensure that each hook head needs to be hooked to the elastic ring; at the same time, the hook line assembly is divided into a hook line and a release bar, with a complex structure, and the spring pressure piece bears all the stress, and its own nature As a result, it is easy to cause metal fatigue to lose elasticity, and it may fall off from the hook line and the release bar; while the hook head of the hook line needs to ensure that the elastic ring does not fall off when hooking the line, and it also needs to ensure that it does not cause excessive damage when the line is off the line. The large resistance causes the release bar to fail to let the elastic ring disengage.

Finally, in the glove pushing device, pushing the glove through the push plate may easily cause the fingers of the glove to bend, and according to the disclosed solution, only one end of the glove can be bound.

Therefore, the inventor further researches this, develops a kind of glove automatic binding rubber band technology, and this case arises thus.

Contents of the invention

The object of the present invention is to provide a process for automatically binding rubber bands on gloves, which can overcome the above-mentioned problems in the prior art.

In order to achieve the above object, the technical scheme of the present invention is as follows:

An automatic rubber band binding process for gloves, including the following binding actions:

Through a rubber band conveying device, the rubber bands used for binding are transported to the rubber band binding device one by one;

After the rubber band binding device catches and expands the rubber band, the rubber band conveying device returns to its position, the rubber band binding device moves to the glove placement platform, puts the rubber band on one end of the stacked gloves, and pushes out the rubber band;

After finishing the binding at one end, return the rubber band binding device to its original position, and wait for the rubber band conveying device to provide the rubber band again. At the same time, the glove placing platform rotates 180° so that the other end of the glove is aligned with the rubber band binding device. After repeating the above actions to complete the second binding, the rubber band is bound The device pushes the glove out of the glove placement platform;

Among them, the rubber band conveying device separates the rubber bands one by one through two horizontal rollers with spiral grooves; the four rubber band claws of the rubber band binding device are first gathered and then expanded, and the rubber bands are grasped through the fixed claws of each rubber band claw. And the rubber band claw moves relative to the fixed claw with the movable claw of the rubber band claw in the process of expanding and moving, and the rubber band is pushed out from the end of the fixed claw.

In the above-mentioned binding process, in the process of conveying the rubber band, by setting two rollers, the rubber band claw can be removed from the gap between the two rollers, and a certain operating error is allowed;

In the bundling of rubber bands, the "four claws" expansion method is adopted, but compared with the prior art, the fixed claws of the present invention are rigid and will not be affected by the tightening force of the rubber bands. Roll out, can avoid the problem described in background technology;

On the placement platform, by setting the glove placement platform, the knitted fabric itself has the ability to adjust its own placement angle, and the gloves can be tied at both ends;

Through the mutual cooperation of the above-mentioned mechanisms, the automatic finishing effect is realized.

Further, the rubber band conveying device makes the bundled rubber bands enter the spiral groove through the rotation of the two rollers to separate from each other, and through the movement of the rubber band conveying device, the separated rubber bands are transported to the rubber band claws of the rubber band binding device, and the four rubber band claws It is in a gathered state; then, the four rubber band claws are pushed into the rubber band circle, so that the fixed claws of the rubber band claws match the rubber band, then the rubber band claws expand outward, the rubber band delivery device moves back, the rubber band delivery device returns to its original position, and the gloves are placed The platform drives the gloves to rotate clockwise 90°, compacts the fluffy gloves and then rises to leave space for the rubber bands to enter. The fixed claws of the rubber band claws move forward with the rubber bands and enter the binding position. The rubber band claws continue to move outward, and the movable claws of the rubber band claws will move The rubber band is pushed out from the fixed claw to bind it on the glove, the glove placement platform is rotated 180° clockwise, and the other side of the glove is bound by repeating the above steps.

Further, the four rubber band claws of the rubber band binding device are driven by the same binding driving mechanism, the binding driving mechanism includes a gear driven by a motor, the gear is linked with several racks, and the racks are linked with their respective rubber band claws.

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

Further, the movement of the movable claw relative to the fixed claw is realized in the following ways:

The movable claw and the fixed claw are arranged side by side, and the movable claw and the fixed claw are connected by a return spring. When one end of the movable claw slides on the boss on the base, the movable claw is raised relative to the fixed claw, so the rubber band is pulled by the other end of the movable claw. Push out; when the movable claw slides out of the boss, the return spring makes the movable claw return to its original position.

The boss of the base is at the position where the rubber band is disengaged after expansion, and is generally located around the base.

Further, the movable claw is arranged on one side of the fixed claw in a relatively movable manner through an adjusting bolt.

The movable claw cannot be tightened by the adjusting bolt, which can be replaced by other parts with similar limit functions.

Further, the glove placement platform includes a main bearing board and a bearing telescopic board, and the bearing telescopic board can be extended or retracted relative to both sides of the main bearing board.

Taking woven gloves as an example, in order to bundle the stacked gloves, the bottom of the glove should be suspended, and once the glove is suspended in the air, it is easy to cause the glove to sag or fall. After binding with the gloves through the rubber band, the load-bearing telescopic plate can be retracted. If the other end of the glove needs to be bound, rotate the main load-bearing plate 180° and repeat the above action.

Furthermore, the rotation of the main bearing plate is realized by the gear set, and the bearing telescopic plate slides in the arc-shaped groove through the linked rollers, thereby pushing the bearing telescopic plate to perform telescopic movement relative to the main bearing plate.

Further, the side of the main bearing plate is provided with an arc-shaped hem for defining the position of the glove.

Further, a lifting pressure plate is provided on the side of the glove placement platform, and the lifting pressure plate is used for compacting the fluffy stacked gloves.

The lifting plate is used to assist in binding the stacked knitted fabrics.

Further, the two rollers of the rubber band conveying device are driven to rotate by the same motor through the synchronous belt.

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

1. The rubber band conveying process ensures that the rubber band will not be entangled or twisted, and 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 band from between the two rollers;

2. The rubber band binding process ensures that the rubber band claws have sufficient rigidity and stability, even if the rubber band is expanded enough, it will not be affected;

3. The platform for receiving and fixing gloves is flexible and diverse.

The bottom plate 15 of the rubber band conveying device 1 is provided with two horizontally arranged rollers 16, and a continuous spiral groove is provided on the roller 16. Driven to rotate, the synchronous belt 17 is driven by another independent driving device. After a bundle of rubber bands is wound on the two rollers 16, the rubber bands 5 can be gradually embedded in the spiral grooves through rotation to realize separation.

The rubber band binding device 2 is arranged on one side of the glove machine and the rubber band conveying device 1, and its specific structure is shown in Fig. 4-7, which includes a relatively vertically arranged base 21, and four chutes 212 arranged at intervals are arranged on the base 21 Each chute 212 is provided with a rubber band claw, the sliding seat 23 of the rubber band claw is linked with the binding transmission structure 22 on the back of the base 21, the sliding seat 23 is provided with a fixed claw 24 vertical to the base 21, and one side of the fixed claw 24 is provided with The movable claw 25 and the end of the fixed claw 24 are provided with an L-shaped limiting groove 241, so that the four fixed claws 24 can grab the rubber band by expanding, and the movable claw can move the rubber band from the limiting groove of the fixed claw 24. 241 launched.

As shown in FIG. 7 , the movable claw 25 is provided with a strip groove, and an adjusting bolt 251 is arranged in the strip groove, and the adjusting bolt 251 restricts the movable claw 25 to the fixed claw 24 side relative to each other. Simultaneously, between movable claw 25 and fixed claw 24, be connected by back-moving spring 26, one end of back-moving spring 26 in the figure is fixed on the fixed claw 24, and the other end has not been hung in the corresponding hanging hole of movable claw 25, according to actual conditions, through Adjust the pretightening force of the adjusting bolt 251 and the tension of the return spring 26 so that the movable pawl 25 can be pushed and reset by the return spring 26 .

The promotion of the movable claw 25 is realized by setting the boss 211 on the base 21. The boss 211 is arranged on one side of the chute 212, and the boss 211 is arranged on the movement route of the rubber band claw. After the rubber band claw expands the rubber band, When the rubber band needs to be disengaged, 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 raised relative to the fixed claw 24, thereby pushing out the rubber band in the limiting groove 241; When the movable pawl 25 slides down from the boss 211 , it returns to its original position under the action of the return spring 26 .

As shown in Figure 6, the binding transmission structure 22 is driven by a second drive motor 221, and the second drive motor 221 drives four second drive racks 222 to move synchronously through a gear set, and each second drive rack 222 corresponds to a rubber band claw .

The whole rubber band binding device 2 is on the second slide rail 27 and can move along the second slide rail 27, and its moving direction is perpendicular to the moving direction of the rubber band conveying device 1 .

The rotary placement platform 3 is arranged on the top of one end of the second slide rail 27, and it mainly includes a main load plate 31 and a load telescopic plate 32. As shown in FIG. 8, the load telescopic plate 32 can stretch out relative to both sides of the main load plate 31 or indent.

In order to bundle the stacked gloves, the bottom of the glove should be suspended, and once the glove is suspended, it will easily cause the glove to sag or fall. Therefore, one end of the glove needs to be supported by the load-bearing expansion plate 32, and the load-bearing expansion plate 32 and the glove are passed through the rubber band. After bundling together, the load-bearing telescopic plate 32 can be retracted. If the other end of the glove needs to be bound, the main load-bearing plate 31180° can be rotated.

Wherein, the rotation of the main bearing plate 31 is realized by the gear set. In FIGS.

The expansion and contraction of the load-bearing expansion plate 32 is realized through the following hierarchy:

Below the main bearing plate 31 is a load-bearing telescopic plate 32, and under the load-bearing telescopic plate 32 is a connection seat 312. Below the connection seat 312 is a half cam and an arc-shaped plate, and an arc-shaped groove 323 is formed between the half-cam and the arc-shaped plate. A roller 321 is arranged on the same plane as the arc groove 323 , and the roller 321 is linked with the load-bearing telescopic plate 32 through a connecting frame 322 .

Take Figure 9-Figure 12 as a reference:

Fig. 9 is the initial state of waiting for gloves to be placed, that is, the initial state of the rotating placing platform 3 in Fig. 1 .

Fig. 10 is the state when the main bearing plate 31 is rotated 90° to bind the rubber band for the first time to one end of the glove, and the roller 321 is not limited by the arc groove 323 at this moment.

Figure 11 is on the basis of Figure 10 and the main bearing plate 31 is rotated 180° again. At this time, due to the restriction of the roller 321, the connecting frame 322 pushes the load-bearing telescopic plate 32 to translate from the right side to the left side, and the other end of the glove that needs to be bound is carried out. lifting.

Fig. 12 shows that after binding the two ends of the glove, it is rotated 180° again in the state of Fig. 11. At this moment, the load-bearing telescopic plate 32 is released from the rubber band again, and the state of the whole device is referred to Fig. 13 .

The side of the main bearing plate 31 is provided with an arc-shaped folded edge 311, which can better limit the position of the glove in this embodiment. The side of the rotary placing platform 3 is also provided with a lifting pressure plate 33, and the lifting pressure plate 33 compacts the fluffy gloves by pressing down, and is used to assist in binding the stacked gloves. The lifting and lowering plate 33 is driven by an independent motor, and can be arranged on one side of the rotating platform 3 as the case may be, as long as the pressing part of the lifting and lowering plate 33 is located above the glove.

The binding process is as follows:

The rubber band conveying device 1 makes the bundled rubber bands enter the spiral groove to separate from each other through the rotation of the two rollers 16, and through the movement of the rubber band conveying device 1, the separated rubber bands are transported to the rubber band claws of the rubber band binding device 2, four The elastic claws are in a gathered state, as shown in Figure 14.

Subsequently, the four rubber band claws are pushed into the rubber band ring, so that the fixed claws 24 of the rubber band claws match the limit slots 241 of the rubber band, and then the rubber band claws expand outward, the rubber band delivery device 1 moves backward, and the rubber band delivery device 1 returns to its original position , the rotating platform 3 drives the gloves to rotate clockwise 90°, 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 fixed claw 24 of the rubber band claw moves forward with the rubber band to enter the binding position, as shown in the figure 15.

As shown in Figure 16, the rubber band claw continues to move outwards, because the movable claw 25 of the rubber band claw is acted by the inclined surface of the boss 211 at this time, thereby pushing the rubber band out from the limiting groove 241 of the fixed claw 24, so that it is bound on the glove (the lower part of the rubber band is to bundle the load-bearing telescopic plate 32 together at this moment).

The rotating placing platform 3 rotates 180° clockwise, and while the load-bearing telescopic plate 32 is retracted, it moves to the opposite side to hold up the other end of the glove 6 waiting to be tied up (that is, the process of the aforementioned Figures 10-11). Lifting pressure plate 33 presses down earlier to compact fluffy gloves and then rises to leave space for rubber bands to enter, and rubber bands on the claws of rubber bands move forward to enter the binding position.

Repeat the above steps to bind the other side of the glove 6. After binding, refer to the state of Fig. 12 and Fig. 13. Finally, the glove can slide into the storage box for placing the glove along the slope on the right.
