Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for processing a stitch-inserted stopper thread in which a stopper thread is inserted into a loop at the end of a bag-knitted fabric in a horizontal striping device, and the inserted stopper threads are bonded to each other. A threading pestle protrudes from one side to the other side to pass through the loop of the final course of the hemmed fabric set on the knitting machine, grips the stopper thread, pulls it in and threads it through, and then holds the stopper thread through the loop on the other side. The present invention relates to a method for processing a stopper thread, in which the stopper thread is pushed in while being held in place, passed through and released, and the start and end ends of the stopper thread are joined to prevent the stopper thread from slipping out of the loop.

The whole land formed by the Yoko-Nuka machine will come undone unless measures are taken to secure the loop of the final course.

Therefore, various measures are taken to prevent greening, and when done manually, a handhold called a winding stop or a hold-down is used; when using a machine, an overlock key is used to connect the final course loop to the previous course loop. The loops are sewn together using an overlock sewing machine, which is extremely time-consuming. Measures have also been taken to join the loops of the final course of striped fabric using adhesive, to fuse them using meltable yarn, or to shrink the stitches using elastic yarn. However, the stitches sometimes hardened and the appearance of the product was damaged. Focusing on these circumstances, the present applicant proposed a method and device for preventing the final line from unraveling. The technical means is to form a loop hook part and a passage groove for the threading rod in a part of the knitting needles, and when the final loop is formed, the bran needles are displaced all at once to form a passage for the threading twill. At the same time, a threading rod was passed through the passageway to insert a retaining thread (Hakama Kaisho 50-1536). That is, as shown in FIG. 2, the knitting needles 1, 1 disposed on the needle beds 5, 5 are provided with an engaging portion 2, a part of which is shown enlarged in FIG. A notch groove 3 is formed on the lower side of the. Then, the bran needles 1 are slightly displaced all at once to form the final loop 4, and one of the threading rods 6 and 6' as shown enlarged in FIGS. 4 and 5 is passed through the notch groove 3. It is something. The threading parts 7, 7 are attached to the threading hakama 6, 6'.
' is formed, and the retaining thread 8 is hooked and inserted. Therefore, the threading rod 6 shown in FIG. 4 is shown hooking the stopper thread 8 and moving in the direction of the arrow, and the threading rod 6 shown in FIG. state.
Therefore, these threading rods 6, 6' move by hooking the stopper thread 8, and two threads of the stopper thread 8 pass through the loop as shown by 8', and the stopper thread 8 passes through the loop in one direction. It was to be passed. Therefore, for example, as shown in Fig. 1, the stopper thread 8 consisting of a single thread or a plurality of threads is inserted into the loops 4 and 4' of the bag-knitted final courses A and A' from one side, and then the loop on the pond side is inserted again. In order to insert the retaining thread in such a manner that the retaining threads are fastened to each other at one end thereof, a plurality of thread passing twills are required, and a delivery device for the retaining thread 8 is also required. Therefore, based on the basic idea of using knitting needles and a stop thread threading twill, a part of the stop thread 8 is held by the thread threader, the thread is inserted through the loop group on one side so as to pull the stop thread, and then the thread is inserted into the loop group on the other side. We proposed a method in which the threading rod is passed through the threading groove that is formed, and the threading thread is inserted into the threading hole while the threading thread is held and pulled in. Furthermore, when inserting the other end loop group, if there is a lot of resistance from the pull-out retaining thread, the required length of the retaining thread that has been inserted through the one-side loop group to be pulled in is stored and inserted. These threading punches are provided with a device that securely engages and grips the stop thread 8, and this thread holding device releases the gripping portion only at the position where the threading village is the most protruding, receives the stop thread, and It was designed to open.

We have also proposed a stop thread hooking device that automatically guides the stop thread to these threading villages and holds the open stop thread end. However, unless a means for connecting these threads is developed, there is a risk that the threads inserted through the loops may unravel or come off. The present invention has been made based on the above, and particularly relates to a method of binding a thread inserted by the above-mentioned threading village and thread hooking device. The gist of this is to provide a holding means for holding both the starting end and the terminal end of the inserted fastening thread, and a joining means for tying or joining the fastening thread, and to move and displace one or the other to hold the fastening thread. This is used to join the fastening threads together. The present invention will be explained below based on the drawings, but the drawings show one example of a concrete implementation of the method of the present invention, and the present invention is not limited to these illustrated examples, but in accordance with the spirit of the above and later descriptions. The same effect can be achieved by changing the design or replacing parts.

FIG. 6 is a front view schematically illustrating an example of a fully automatic glove knitting machine 9 to which the present invention is applied, in which a retaining thread processing means 12 of the present invention is provided across a group of knitting needles of a needle bed 5, and a threading punch device 11 It is arranged on the other side of the knitting machine 9 and fixed to the knitting machine 9 via a placket. The threading device 11 is constructed of the above-mentioned stop threading device and its driving device 15 as shown in FIGS. 7, 8 and 9. That is, FIG. 7 is a partial configuration diagram with the central portion omitted, FIG. 8 is a sectional view taken in the direction of the arrow along the cutting line of FIG. 7, and FIG. 9 is an explanatory diagram of the operation. In these figures 1
Reference numeral 9 indicates a threading punch, and the threading punch 19 is formed of a cylindrical shaft having a length at least longer than the arrangement length of the fin needle group 1, as shown in FIG. ′ is formed.
Also, closing parts 21 and 22 are formed near the tip and rear ends, and the closing part 21 serves as a stopper thread holding part, and the closing part 2
2 constitutes a sliding regulating section. A sliding shaft 20 is movably housed in the threading punch 19 formed of a cylindrical shaft, and a locking member 23 is arranged in the regulating opening 22 so as to protrude from the top surface of the threading punch 19. A tree will be erected. The sliding shaft 20 is always biased toward the protruding side (toward the knitting needle group 1 side) via a spring 25, and a lid 25' is formed on the rear end side of the threading village 19. Further, the gripping and closing portion 21 is configured such that the sliding shaft 20 is biased to hold the retaining thread, and the sliding shaft 20 is configured to hold the retaining thread at the closing portion 2.
1, the locking member 23 is configured to leave some space in front of the opening 22 even when it is in contact with the wall formed at the tip of the locking member 23. Therefore, by moving the locking member 23 protruding from the threading village 19 to the retreating side while compressing the spring 25, the sliding shaft end of the lever opening 21 can be moved back and closed as shown in FIG. I hope you understand. The threading village 19 configured in this way is slidably held on the support tube 18, and
The lower part of the groove forms an open groove along its entire length. The threading shaft 19 slides smoothly within the support tube 18, and the sliding movement is driven through the open groove of the support tube 18. In order to ensure these drives, rack teeth 26 are formed at the lower part of the threading punch 19 to engage with the drive pulley 27, but the rack teeth 26 are omitted and the drive pulley 27 is Alternatively, the rack teeth 26 may be replaced with another friction material and brought into contact with the drive pulley 27.The point is that the threading village 19 smoothly threads the loops of the knitted fabric and the knitting needles 1. It is configured such that it passes through the groove portion 3 of. Therefore, instead of the support tube 18, it may be slidably supported by a ball bearing, or instead of the drive pulley 27, a steel band or a steel wire may be connected to the threading village 19 and driven. Good too. Reference numeral 24 denotes a regulating piece that is adjustably attached to the support cylinder 18, and the regulating piece 24 is attached to the threading punch 1.
9 to restrict the protruding position of the threading village 19, and also slide the locking member 23 to move the sliding shaft 20 backward (in the protruding direction) as shown in FIG. (to regulate port movement) and open the retainer opening section 21.

Although the regulating piece 24 is shown as being fixed to the support tube 18, it may be configured to be attached to another fixing member to support the locking member 23, or the protrusion of the threading punch 19 may be restricted. It may be configured separately. Also, the drive pulley 27 threads Azusa 1.
When the protruding position of the slide shaft 9 can be regulated, the regulating piece 24 may simply be used to restrict the movement of the sliding shaft 20 in the protruding direction. When the threading punch 19 thus configured is moved to the protruding tip, the thread gripping portion is opened as shown in FIG.
It becomes obstructed as soon as it begins to retreat. On the other hand, the processing means 12 is provided corresponding to the threading punch device 11 and is constructed as shown in the side view of FIG.

That is, a mounting plate 29 is attached to a bracket 28 fixedly provided on the knitting machine 9, and the swing motion device 3 is attached to the mounting plate 29.
0 and a drum support rotation device 31 are attached, and the drum support rotation device 31 is swingably supported by the swing movement device 30. A placket 35 is fixed to the lower surface of the rocking motion device 30, and a bracket 36 is fixed to the top surface of the drum support and rotation device 31 to pivotally support each other, and the electromagnetic actuation member 37 is fixed to the rocking motion device 301 Then, the operating punch 38 is pivotally supported on a bracket 36 fixed to the upper surface of the drum support rotation device 31. Therefore, when the electromagnetic actuating member 37 is magnetically excited, the actuating punch 38 rises and swings the drum support rotation device 31 to the position shown by the dotted line. Further, when the magnetic excitation is removed, the solid line is maintained by its own weight or by a return spring provided in the electromagnetic actuating member 37. A drum 32 is freely supported on the front side of the lower part of the drum supporting and spreading device 31 by a supporting lacquer part 33, and the drum 32 is configured to reciprocate at a constant angle. FIG. 11 is a front view of the drum support and rotation device 31, partially cut away, and FIG. 12 is a direction of the arrow along the cutting line Yanagi-Kari in FIG. 11 showing the inside of the spreading device. FIG. That is, a toothed row 39 is formed on the outer periphery of the drum 32, and the drum 32 is supported by a support portion 33 with the toothed row 39 in between so as to rotate smoothly via a bearing or the like. A rack village 40 is slidably provided so as to engage with the toothed row 39 of the drum 32, and an operating lever 42 is engaged with a pin 41 provided in the rack village 401. As shown in FIG. 12, the actuating lever 42 is pivotally supported by an actuating member 45 of an electromagnetic actuating member, such as an attraction type magnet 44. 4
3 shows the guide rail of the rack village 40.

The drum support and rotation device 31 configured in this manner operates the actuation lever 42 to the position shown by the dotted line 42' through the actuation village 45 by energizing the electromagnetic actuation member 44, and this actuation rotates the drum 32 by approximately 240 degrees. . When the electromagnetic actuator village 44 is de-energized, a spring built into the electromagnetic actuator village 44 or a return spring 42'' provided in a part of the actuating lever 42 returns to the position indicated by the solid line, and the drum 32 returns to reverse rotation. On the other hand, there is a hole 48 (first hole) in the center of the drum 32 in the direction of the ball.
3), and a groove 46 that fits into the hole 48 is formed on the rear side of the drum 32, and the rear end edge is formed with a circular curved surface.

A part of the split groove 46 has a hole 48 and a notched groove 4 through which the groove is inserted.
7 is formed, and a part of the trailing end of the split groove 46 or a thread hanging piece 49 is formed. Then, as shown in FIG. 10, the threading village 1
9 is held in position so as to protrude and be inserted into the hole 48 of the drum 32, and the thread holding opening 21 thereof reaches the groove 46 of the drum 32, so that the protrusion of the threading hole 19 is restricted. be done. And on the rear side of the drum 32 there is a trumpet-shaped opening □
As shown in FIG. 6, the suction nozzle 13 is fixedly connected to the suction side of a fan device 14 fixedly installed on the knitting machine 9. The drum 32 holds the retaining thread by the suction airflow of the suction nozzle 13, and can be pivoted as shown by the dotted line in FIG. 20 by the swing motion device 30. By the way, the essential part of the present invention is that a retaining thread joining/cutting device 34 as shown in FIG. 10 is provided at this drum rocking displacement position, and this device is fixed to the mounting plate 29 via an arm 34'.

Although the details of the stopper thread joining and cutting device 34 are not shown in the drawings, the stopper thread joining and cutting device 34 utilizes a thread tying machine and a cutting device that have been used in conventional yarn handling machines. When the thread is a thread), it may be joined by heat-sealing means, and the joined end may be cut and separated. FIG. 13 shows the loop 4 of one final course A of the bag knitting shown in FIG.
9 is shown protruding, and the drum 32 of the yarn processing means 12
is held in the position shown in the cross-sectional view of FIG. 15, and the tip 8'' of the stopper thread 8 is suction-held by the suction nozzle 13 via a suitable guide member, and a part of it is positioned so as to be in contact with the drum 32. Then, when the threading village 19 is fully protruded and its holder opening 21 reaches the split groove 46 of the drum 32 as described above, the holder comes to a stop as shown in FIG. 14. Next, the electromagnetic actuating member 44 of the drum support and rotation device 31 is magnetically excited to rotate the drum 32 by about 240 degrees. Due to this rotation of the drum, the stopper thread end 8'' shown in FIG.
The threading hole 19 is guided around the threading hole 19 by the split groove 46 and threading piece 49 as shown in FIG. As shown in FIG. 2, when the thread retainer 19 begins to retreat, the retainer opening is closed, retains the retaining thread 8, retreats, returns through the loop 4, and inserts the retainer thread 8 into it. The locking thread 8 can be freely drawn out via the drum 32 and is pulled out via a suitable tensioning device.The locking thread 8 is thus passed through the loop 4 on one side, and then the threading punch 19 is pulled out. This is to pass the pinned thread 8 through a path made up of other knitting needle groups, but the thread 8 passing through the loop group has considerable resistance, and the length of the thread forming the return path must be adjusted in advance. It may be preferable to provide a means for holding the drawer on the drawer side. Fig. 17 shows an example of this.
A retaining thread storage device 50 that moves in one direction in contact with the retaining thread 8 pulled out by the threading punch 19 is illustrated, and this device is composed of a swinging arm 51 and a guide pulley 52 loosely supported at the tip of the arm. 51 is swung as shown by a dotted line 51' to temporarily store the retaining thread 8. Next, as shown in FIG. 18, the threading tube 19 is inserted through the loop 4' formed on the side of the thread so as to push in the retaining thread 8. Then, when the threading punch 19 enters the drum 32 again and the lock-holding entrance 21 is opened, the starting end 8'' of the fastening thread that has been held as described above is released, and at the same time, this thread end 8
'' becomes the starting end and is sucked and held by the suction airflow of the suction nozzle 13. As a result, the threading punch 19 becomes bare, moves backward through the loop 4', and returns to the preparation position shown in FIG. 6. Meanwhile, the drum 32 In this state, as shown by the solid line in FIG. 20, the terminal end of the retaining thread 8 is guided by the split groove 46, and the starting end thereof is guided by the hole 48.

Next, the drum 32 is displaced to the dotted line 32' by excitation of the electromagnetic actuating member 37 by the rocking motion device 30, and the stopper thread 8,
8 to the stopper thread joining and cutting device 34. The retaining threads 8, 8 introduced into the layer 34 are joined as described above, and their ends are cut. Therefore, as shown in FIG. 21, the cut end is sucked in by the suction force of the suction nozzle 13, and a new retaining thread starter 8'' is formed.Then, the drum 32 is reversed at the same time or before returning to the standby position. The retaining thread end 8'', which has been suctioned and held through the hole 48, is guided to the outer periphery through the notched groove 47 formed in the drum 32 and restored as shown in FIG. Note that, if necessary, the swing motion device 30 of the drum 32 may be omitted and the retaining threads 8, 8 holding the retaining thread joining and cutting device 34 as shown in FIG. 23 may be used.
They may be joined by moving as indicated by the arrows at ', or they may be brought together and joined.

Furthermore, these joining devices 34 utilize various knotters conventionally used in the textile industry as described above, joining means using adhesives, or stopper threads using heat-fusible fibers. The bonding may be performed using a simple heater. Further, although these joining devices 34 are shown as being equipped with a thread cutting device, this cutting device may be constructed separately and configured to act on the retaining thread extending between the joining device 34 and the drum 32. can also be implemented in the same way. As described above, in the present invention, the threading punch 19 grips the stopper thread and passes through the loop group, and the starting end and the terminal end of the stopper thread are held by the holding means, and the joining device is applied all at once. Because of this, the stopper thread can be easily connected, the thread insertion process for preventing stitch unraveling can be carried out extremely rationally, and these operations can be mechanized, contributing to a reduction in production costs.
