Description

Lace weaving apparatus having cutting function

The present invention relates to a lace weaving apparatus having a cutting function capable of weaving lace, cutting the lace woven in two layers, and applying a functional liquid.

Lace refers to a decorative fabric processed so that there is a space in which rather complex pattern elements made by intertwisting threads are connected with a mesh or decorative connecting nose.

The weaving device may weave a lace that twists the yarn to form a pattern. The spools on which the thread is wound are disposed on the frame (eg, annular frame) of the weaving apparatus, and the yarns fed through the spools are twisted in the weaving unit to produce a lace. The woven lace is conveyed through a conveying section on which rails and a plurality of rollers are arranged.

The lace has a band shape in which both sides are straight, and a pattern may be disposed between the bands. (For example, an insertion lace lace is woven with a belt-like member disposed long in the longitudinal direction, Patterns may be arranged symmetrically with respect to the center of width Accordingly, if necessary, if the lace is cut based on the center of width, two laces having the same pattern are manufactured.

The lace may be supplied to the conveying unit in a folded state, that is, in a state of two layers, based on a fold line disposed at the center of the width. Therefore, if necessary, in order to manufacture two laces having the same pattern, it is inconvenient for an operator to manually cut the fold line. In addition, if such a cutting operation is not performed in the process of transporting the lace, cutting is performed through a separate cutting process, thereby increasing the manufacturing process and manufacturing time of the lace. In addition, since it is necessary to go through a separate reprocessing process in order to add an antibacterial function to the lace or to give a fragrance, there is a problem in that the manufacturing process and manufacturing time increase.

This front roller 210 serves to guide the race 1 to the cutter 300 . In addition, the front roller 210 serves to apply the functional liquid (W). The configuration of the front roller 210 for applying the functional liquid (W) is as follows.

The roller 206 of the front roller 210 may include a first shaft portion 201 , a roller body 202 , and a nonwoven fabric 203 . The roller body 202 is coupled to the outside of the first shaft portion 201 . The nonwoven fabric 203 is coupled to the outer peripheral surface of the roller body 202 . The first shaft portion 201 may include a storage portion 201a for accommodating the functional liquid (W). The roller body 202 is formed with an injection port communicating with the storage unit 201a, so that the operator can fill the functional liquid (W) through the injection port.

The roller body 202 is formed of a microporous member, and may be formed to communicate with the storage unit 201a. Therefore, when the roller 206 of the front roller 210 rotates, the functional liquid W accommodated in the storage unit 201a penetrates into the roller body 202 by centrifugal force. The functional liquid (W) penetrating into the roller body 202 permeates into the nonwoven fabric 203 . The functional liquid W permeated into the nonwoven fabric 203 is applied to the lace 1 .

Here, the functional liquid (W) may be an aqueous solution containing an antibacterial agent or an aqueous solution containing a fragrance.

The front roller 210 may be formed to selectively apply various functional fluids (W) or to guide the race (1) toward the cutting part (30) without applying the functional fluid (W). For example, the front roller 210 may include a second shaft portion 204 , a plurality of connecting bars 205 , and a roller 206 connected to the connecting bar 205 . The second shaft portion 204 is disposed on the frame 100 and is disposed along the left-right direction (y). The plurality of connecting bars 205 are disposed in a radial direction with respect to the second shaft portion 204 . For example, all three connecting bars 205 may be arranged at intervals of 120° with respect to the second shaft portion 204 . A roller 206 is connected to an end of each connecting bar 205 so as to be sinterable. For example, all three rollers 206 may be disposed on the front roller 210 . When the operator rotates the second shaft portion 204, the three rollers 206 move along the first circular track O1 or the second circular track O2, while any one of the three rollers 206 races. It can be located on the transport path of (1).

Only some of the three rollers 206 may include the aforementioned storage unit 201a, the roller body 202 and the nonwoven fabric 203 . For example, two of the three rollers 206 may be for applying the functional liquid W, and the other roller 206 may only be for guiding the race 1 .

The shape of the front roller 210 may be implemented in both the upper front roller 211 and the lower front roller 212 . However, in the upper front roller 211 , the radius R1 of the first circular track O1 on which the rollers 206 moves is the second circular track on which the rollers 206 move in the lower front roller 212 . It may be smaller than the radius R2. That is, the length of the connecting bar 205 of the lower front roller 212 may be longer than the length of the connecting bar 205 of the upper front roller 211 .

The race 1 supplied to the cutter 300 may be cut and separated into an upper race 1a and a lower race 1b. The cutter 300 may be disposed on the transport path of the race 1 .

One edge of the cutter blade 320 is caught by the protrusion 311 disposed on the separator 310 , and movement is limited even by the restoring force of the elastic member 330 .

The fold line L of the race 1 is changed in position as shown in L' in FIG. 4 as the running direction of the race 1 is slightly changed despite the guidance of the roller unit 200, and the left and right direction (y) ) deviation (d) may occur. Even if the position of the fold line L is changed, the elastic member 330 may naturally change the position of the cutter blade 320 to match the position of the fold line L in response thereto. In addition, when the position of the fold line L of the race 1 in the left and right direction y greatly deviates from the position of the cutter blade 320, the operator can directly adjust the position of the separator 310 in the left and right direction (y). . The cutter 300 may include support parts 350 and 360 connecting the separator 310 and the frame 100 . The supports 350 and 360 may include a first part 350 connected to the frame 100 and a second part 360 slidably coupled to the first part 350 and connected to the separator 310 . .

At this time, the leg portion 102 is arranged to be stretchable in length in the vertical direction (z). When the length of the leg portion 102 is extended, the upper front roller 211 and the upper rear roller 221 move upward to move away from the race 1, respectively, and contact with the race 1 is released. In addition, when the length of the leg portion 102 is increased, the lower front roller 212 and the lower rear roller 222 move downward to move away from the race 1, respectively, and contact with the race 1 is released. At this time, the cutting portion 30 is also deviated from the transport path of the race (1). In this way, the operator adjusts the vertical direction (z) position of the roller unit 200 and the vertical direction (z) position of the cutter 300 as needed to advance or omit the cutting operation or the application operation of the functional liquid (W). can do.

Meanwhile, the lower frame 120 may be detachably disposed on the upper frame 110 . Accordingly, the upper frame 110 and the lower frame 120 may be separated from each other, removed from the rail 21 , and mounted again, if necessary.
