As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 and 2, a rope cutting apparatus 100 according to an embodiment of the present invention includes a material roll holder 110, a rope combing shaft 120, a traction device 130, and a cutting device 140.

The roll stand 110 is used to set a plurality of rolls. The rope carding shaft 120 is provided with a plurality of rope placing grooves 142 along the axial direction. The traction device 130 includes a first conveyor roller 132, a second conveyor roller 134, and a rotation driver (not shown), the first conveyor roller 132 and the second conveyor roller 134 are disposed opposite to each other, and the roller surfaces are pressed against each other, and the rotation driver is connected to the first conveyor roller 132 and/or the second conveyor roller 134 to drive the first conveyor roller 132 and the second conveyor roller 134 to rotate in opposite directions. The pulling device 130 is used to pull a plurality of ropes passing through the combing shaft 120 into the shearing device 140.

As shown in fig. 2, the roll stand 110 can set a plurality of rolls at different heights. In one example, the roll stand 110 includes a base 112 and a column 114 disposed on the base 112, and the column 114 is provided with a plurality of roll inserting rods 116 for disposing rolls at different heights.

In one example, the roll insertion rods 116 are disposed at 3-10 different heights of the vertical posts 114, such as 4, 6. In the specific example shown in fig. 2, two roll-insertion rods 116 are provided at 5 height positions on the vertical column 114, respectively, and the two roll-insertion rods 116 are provided on opposite sides of the vertical column 114. Each material roll inserting rod 116 is arranged obliquely upwards, so that material rolls can be conveniently inserted, and meanwhile, the material rolls are prevented from falling.

As shown in FIG. 2, in one example, a plurality of columns 114, such as 2-10 columns, are disposed on the base 112, and the columns 114 are arranged in sequence toward the card line shaft 120. Further, between the plurality of posts 114, roll-inserting bars 116 provided at respective heights are aligned. In this way, the plurality of roll inserting rods 116 on the roll rack 110 are arranged in a regular and ordered spatial array.

In the specific example shown in fig. 2, 4 vertical posts 114 are provided on the base 112, each vertical post 114 is provided with a material roll inserting rod 116 at 5 height positions, and the material roll inserting rods 116 provided at the respective heights are aligned among the multiple vertical posts 114. Thus, in this example, there are 40 roll insertion rods 116 on the roll rack 110, and 8 roll insertion rods 116 at 5 height positions, respectively, to achieve a maximum of 40 hang tag strings cut at a time.

As shown in FIG. 2, in one example, the lower portion of the upright 114 is also provided with diagonal braces 118 to stiffen the upright 114.

As shown in fig. 1 and 2, in one example, the rope cutting apparatus 100 further includes a lead frame 150, the lead frame 150 is disposed between the material winding frame 110 and the rope combing shaft 120, the lead frame 150 is provided with a plurality of rope penetrating rods respectively distributed at different heights, and each rope penetrating rod is provided with a plurality of rope penetrating holes 152 distributed in parallel. After a plurality of tag ropes are pulled out from a plurality of material rolls on the material roll frame 110, each tag rope respectively passes through one rope threading hole 152 and is led out to the rope combing shaft 120 through the rope threading holes 152, so that the condition that the plurality of tag ropes are mutually staggered and wound can be reduced.

Further, as shown in fig. 2, in one example, there are a plurality of lead frames 150, such as 2-5 lead frames, and the plurality of lead frames 150 are sequentially arranged at intervals along the direction from the material roll frame 110 to the combing rope shaft 120. In the direction from far away from the rope combing shaft 120 to near the rope combing shaft 120, the number of the rope threading rods on the lead frame 150 is decreased gradually, the height of the rope threading rod with the highest height is decreased gradually, and the height of the rope threading rod with the lowest height is increased gradually. In this way, the hang tag ropes led out from the material rolls originally distributed at high and low positions on the material roll frame 110 are gradually converged to the position of the rope combing shaft 120 in the vertical direction.

In the specific example shown in fig. 2, the rope cutting apparatus 100 is provided with two lead frames 150 between the stock reel 110 and the combing shaft 120.

Wherein, the lead frame 150 near the material roll frame 110 is provided with a row of threading holes 152 at 5 height positions. The 5 height positions correspond to the height positions of the coil inserting rod 116 set by the coil rack 110. Each row of the stringing holes 152 has 8 holes, and the number of the stringing poles is the same as that of the material roll inserting poles 116 at the same height position. Therefore, the hang tag rope on each coil rack 110 can pass through the rope through hole 152 at a corresponding height position, so that the hang tag ropes are led out orderly and are not easy to intertwine. It is understood that in other examples, the number of the stringing holes 152 in each row may be more than the number of the material roll inserting rods 116 at the same height position.

As shown in fig. 2, a lead frame 150 adjacent to the coil frame 110 is attached to the post 114. More specifically, the lead frame 150 includes a connecting bar and a stringing bar. Wherein the rope threading rod is horizontally arranged. The rope threading hole 152 is formed by winding a steel wire provided on the rope threading rod. The rope-threading rod is connected to the upright 114 by a connecting rod.

In the specific example shown in fig. 2, the lead frames 150 near the cord carding shaft 120 are each provided with one cord threading bar at 3 height positions. Compared to the lead frame 150 near the reel stand 110, two stringing poles of the lead frame 150 having the highest and lowest heights are close to the stringing shaft 120 in the vertical direction. The middle row of lacing holes 152 is at the same height as the position of the card line shaft 120. The tag line passes through the threading hole 152 of the previous lead frame 150 and then passes through the threading hole 152 of the lead frame 150, so that the tag line gradually converges toward the position of the card line shaft 120 in the vertical direction.

As shown in fig. 2, the lead frame 150 adjacent to the grooming shaft 120 includes a support post and a stringing pole. Wherein the rope threading rod is horizontally arranged. The rope threading rod is arranged on the supporting column. The support posts are disposed on the base 112 of the coil holder 110. The stringing hole 152 is formed by drilling on the stringing rod. The rope penetrating rod is further provided with a notch above each rope penetrating hole 152, and the notches are communicated with the corresponding rope penetrating holes 152, so that the hanging tag ropes can be conveniently placed in the rope penetrating holes 152.

As shown in fig. 1 and 2, in one example, the rope cutting apparatus 100 further includes a rope breakage detecting device 160, and the rope breakage detecting device 160 is disposed between the combing shaft 120 and the lead frame 150 closest to the combing shaft 120.

Further, as shown in fig. 2, the rope breakage detecting device 160 includes a detecting frame 162 and a first controller (not shown). The test rack 162 is provided with a plurality of test holes 164. In the particular example shown, the plurality of test holes 164 of the test carriage 162 are divided into upper and lower rows. The first sensor is disposed on a wall of the detection hole 164. The first controller is electrically connected to the first sensor and the traction device 130. When the first sensor does not sense that the rope passes through the corresponding sensing hole 164, the first controller controls the traction device 130 to stop, thereby preventing a quantity error in packing. When the first sensor senses that the rope passes through the corresponding detecting hole 164, the first controller controls the traction device 130 to operate. Wherein the first sensor may be an infrared sensor. In other examples, the rope breakage detection device 160 may be a commercially available device.

It will be appreciated that the card wire shaft 120 is disposed proximate the nip of the first conveyor wheel and the second conveyor wheel. Preferably, the card line shaft 120 is parallel to the nip of the first conveying wheel and the second conveying wheel, facilitating the feeding of the tag line from the card line shaft 120 to the traction device 130. After feeding, the plurality of tag hanging ropes obtain the same conveying speed along with the rotation of the conveying wheel, and the plurality of tag hanging ropes are cut off simultaneously when conveyed to the shearing device 140, so that short ropes with equal length can be obtained.

It is understood that the rope discharge groove 142 is provided at least at an upper portion of the rope carding shaft 120. In the particular example shown in fig. 2, the payout eye 142 is disposed circumferentially around the grooming shaft 120. In one example, the rope placing grooves 142 on the rope combing shaft 120 are distributed at the same intervals.

In one example, the first conveyor roller 132 is a grinding wheel and the second conveyor roller 134 is a rubber covered roller. The rotation driver drives the first conveying roller 132 to rotate.

As shown in fig. 2, the first conveyor roller 132 and the second conveyor roller 134 are disposed on a base 136. The rope breakage detecting device 160 and the rope combing shaft 120 are also arranged on the base 136, so that the whole structure is compact. In one example, the first conveyor roller 132 and/or the second conveyor roller 134 are adjustable in position, for example, the second conveyor roller 134 (rubber roller) is adjustable in position, which can achieve adjustment of the feeding position. Further, the roller shaft of the first conveying roller 132 and the roller shaft of the second conveying roller 134 are connected by an elastic member (e.g., a spring) to press the roller surfaces of the first conveying roller 132 and the second conveying roller 134 against each other.

In one example, the rotational speed of the first conveying roller 132 is adjustable. In one example, the first conveying roller 132 may rotate in forward and reverse directions. In one example, the traction device 130 also includes a revolution counter to record the number of revolutions of the conveyor roller.

As shown in fig. 1 and 2, in one example, the rope cutting apparatus 100 further includes a conveyance control device 170, and the material receiving box 170 is disposed between the traction device 130 and the cutting device 140.

Referring further to fig. 3, the transport control device 170 includes a material receiving box 170 and a second controller (not shown). Wherein, receive the material case 170 and have upper portion open-ended and receive material chamber 174, receive the material chamber 174 middle part and can hang the matte 176, be provided with the second inductor on the lateral wall of receiving the material chamber 174, second controller and draw gear 130 and second inductor electric connection, sense the matte 176 when the second inductor, second controller control draw gear 130 stop the action, do not sense the matte 176 when the second inductor, second controller control draw gear 130 action.

Wherein, the second sensor can be a photoelectric sensor. In the particular example shown in FIG. 3, the second sensor includes a light emitter 178 and a reflector 179 (e.g., a glass lens), both of which are disposed on and opposite the side wall of the material receiving chamber 174.

Because the shearing speed of the operator cannot be well matched with the conveying speed of the traction device 130, the shearing speed is high, the conveying of the traction device 130 cannot be followed, the shearing speed is low, and a plurality of hang tag ropes are stacked on the ground and are easy to be intertwined in a staggered manner, so that the shearing precision is influenced. In the present example, the conveyance control device 170 is designed to solve this problem.

Specifically, a piece of shielding cloth 176 naturally hangs down from the receiving cavity 174, and after being conveyed by the traction device 130, the hang tag rope is sent into the receiving cavity 174, passes through a gap between the shielding cloth 176 and the bottom of the receiving cavity 174 on one side of the shielding cloth 176, is pulled out of the receiving cavity 174 from the other side of the shielding cloth 176, and is cut in the cutting device 140. When the rope in the material receiving cavity 174 is long enough, the shielding cloth 176 cannot be pulled up by the rope, the second sensor senses the shielding cloth 176, the second controller controls the traction device 130 to stop running, and the rope is prevented from being stacked and is prevented from being wound in a staggered mode. Along with the cutting, the hang tag rope is continuously pulled out of the material receiving cavity 174, the hang tag rope can pull up the shielding cloth 176, the shielding cloth 176 cannot be sensed by the second sensor, the second controller controls the traction device 130 to continuously operate at the moment, the hang tag rope is conveyed into the material receiving cavity 174, and when the shielding cloth 176 is put down, the traction device 130 stops operating again. Thus, the above problems can be solved.

As shown in fig. 4, in one example, the shearing device 140 includes a shearing table 142, and a shearing blade 144 and a measuring mechanism 146 disposed on the shearing table 142, the measuring mechanism 146 is disposed adjacent to the shearing blade 144, and a reference mark of the measuring mechanism 146 is aligned with a blade edge of the shearing blade 144. The cutting device 140 may alternatively be a cutting machine and have a measuring mechanism 146 disposed thereon. In the particular example shown in fig. 4, the measuring mechanism 146 is a straight edge, and the zero scale of the straight edge is aligned with the cutting edge of the cutting knife 144, which greatly facilitates the operation. The operator pulls the plurality of tag hanging ropes from the receiving box 170 through the knife edge of the shearing knife 144 until the preset rope length, that is, the plurality of tag hanging ropes can be cut off at one time and the rope lengths are consistent.

Further, the present invention also provides a rope cutting method, which uses the rope cutting apparatus 100 of any of the above examples, and comprises the following steps:
