Description

Description: TECHNICAL FIELD The present invention relates to a Shino-joining method in a spinning machine and a Shino-joining machine preferable for carrying out the method. For more details, when the Shino-maki bobbin hanging on the bobbin hangers in the front and rear two rows of the creel of the spinning machine becomes a small ball, just before and after the small ball bobbin being spun on the front of the Shino The present invention relates to a method for connecting the Shino end of a full bobbin suspended on a bobbin hanger of a spare rail provided, and a Shino joining machine for carrying out the method.

[Conventional technology and its problems]

As is well known, the Shinobu bobbin hanging on a bobbin hanger of a spinning machine has only a slight twist, as is well known, and therefore has a very weak tensile tension and can be broken by only lightly pulling. For this reason, the Shino jointing work has conventionally been carried out manually, but the invention of the applicant developed for the purpose of automating this work is disclosed in Japanese Patent Laid-Open No. 62-53426, "Method for replacing Shino Shinko spinning machine", and Japanese Patent Laid-Open No. 62-53425. "The Shino exchange for spinning machines" is open to the public. In the Shino exchange of this disclosed invention, when the front row Shinobaki bobbins become small balls, a plurality of (six in the embodiment) small bobbins in the front row and a plurality of (six in the embodiment) spare bobbin full bobbins are set. We are carrying out Shinotsugi work as well as replacement. Since the full bobbin in the front row and the middle bobbin in the back row being spun have to be exchanged before the next Shino exchange, only the spinning machine equipped with the exchanging machine is required to carry out this Shino exchange. There are practical problems.

In order to solve such a problem, a method of simultaneously replacing a pair of empty bobbins in the front and rear and two full bobbins of a spare rail has been proposed in, for example, JP-A-61-119728 and JP-A-61-102428. However, all of them only automate the work of replacing the empty bobbin with the full bobbin. In the case of this exchange, a total of four pegs, two empty bobbin pegs and two full bobbin pegs, are moved three-dimensionally in different trajectories, resulting in a complicated structure and a large space. It is difficult in terms of design to incorporate each device required for Shinotsugi into these devices because of the necessity. If the simplification of this device is attempted and two Shino joints and Shino exchanges are simultaneously performed as disclosed in Japanese Patent Application Laid-Open No. 62-6298 filed by the applicant, the time required for Shino exchange for each weight becomes long. (Three times more than the Shino exchange in JP-A-62-53425). It takes a long time for one fine spinning machine having 240 spindles or more per side, which is not preferable in practice.

[Means for solving problems]

Therefore, the present invention aims to solve the above problems by independently performing the sash jointing work and the sashiwa exchange work to achieve full automation of the sash joint work. A full bobbin support head equipped with at least two rotatable pegs on the main body of the splicing machine, and a shino end withdrawing device for rotating the full bobbin in the rewinding direction to eject the shino end and pull out the shino end of a predetermined length.
Equipped with a Shinotsu head that connects the Shino end that has been spouted to the Shino drawn from the small ball bobbin that is being spun, and a Shino hanging device that hangs the Shino of the full bobbin that has been Shino to the roving guide,
These devices are operated in a predetermined cycle to carry out unit joining work, and are automatically carried out sequentially from one side of the machine base to the other end.

[Work]

When a Shinobaki bobbin hung on a bobbin hanger of a creel turns into a small ball, rotate at least two full bobbins in the rewinding direction to bring out the Shino end, and move the Shino end back and forth. The unit is to overlap the Shino drawn from the pair of spun small bobbins with the Shino splicing and to divide the Shino of the small ball bobbin upstream of the Shino joint and then to hook the Shino to the roving guide. It is a continuation work. This Shino-Join machine successively performs Shino-Join from one end to the other end of the machine base, and the Shinobu of the full bobbin suspended on the spare rail is spun on the roving guide.

It is reliably guided into the guide groove 132. Then, the pipe opening 89a of the lead-out member that has returned to the standby position is pulled out from the full bobbin because it is sucking at a position below and behind the groove bottom 133 of the shino guide groove 132 (position at the lower left of FIG. 5). The shino is pulled by the pipe port 89a, and the shino in the shino guide groove 132 is in a state of being attached to the curved groove bottom 133. At this time, the air cylinder 137 for grasping
When the piston rod 138 protrudes, the shino of the full bobbin is grasped between the shino grip lever 134 and the nip piece 142, and the shino fits into the concave groove 144a of the shino guide plate 145. After gripping the Shinobu of the full bobbin 1, the actuator 102 is normally rotated again and the tube mouth 89a of the output member 89 is swung upward to the vicinity of the Shino gripping lever 134 (position of virtual line III in FIG. 5). The actuator 102 is reversed to return the lead-out member 89 to the standby position again. Then, the downstream portion of the shin grasped by the shino grasp lever 134 is combed and separated by the comb-shaped needle 92 that is planted on the upper side of the tube mouth 89a to form a writing-tip-shaped shin end. The separated Shino is stored in the filter box 94.

Next, while rotating the peg rotation motor M2 again in the rewinding direction, the Shino joint head swing cylinder 157 is operated to immerse the piston rod 158 so that the main body 131 of the Shino joint head 130 is located above the trumpet 6 at the Shino joint position. When moving to, the Shinobu of the small bobbins 2F, 2B being spun are guided by the Shino guide groove 132 of the main body 131 of the Shinotsu head and guided to the groove bottom 133, and spun when reaching the Shino joint position at the forward end. Shino of the inner small bobbins 2F, 2B are gripped by the Shino gripping lever 134 and are pressed against the Shino of the full bobbin 1 hanging on the curved groove bottom 133 to be superposed. The shining air cylinder 137 is operated to rotate the shining lever 134 to the neutral position to release the shining of the full bobbin. The released full bobbin 1 Shinobu is guided to the spinning small ball bobbins 2F and 2B Shino,
After the Shino end of the full bobbin 1 is nipped by the back roller of the drafting unit together with the Shino, the Shino gripping air cylinder 137 is operated and the Shino gripping lever 134 is further rotated to form the nip piece 143. Grip the small bobbin 2F, 2B between. Then Kodama Bobbin Shino is a draft part 16

As described above, when the Shino joint head 130 swings forward and is in the Shino joint position, the engaging pin 195 of the slide plate 191 engages with the engaging portion 56a of the arm piece 56 of the lifting body 53 of the full bobbin supporting head 40. Since this is possible, the full bobbin 1 that has been spliced by the raising and lowering of the elevating body 53 is returned to the bobbin hanger 15 of the spare rail 13, and the shinobi of the full bobbin 1 is hooked on the roving guide 10. The lower front views of FIGS. 13 (a) to 13 (d) are front views at the positions of (a) to (d) indicated by phantom lines in FIG. 9, and are the front views of FIGS. 13 (a) to (d). The top plan view is the plan view at that position. The sashing work will be described below with reference to this drawing.

When the Shino joint is completed, the Shino gripping lever 134 is returned to the neutral position to release the Shino grip of the small bobbins 2F, 2B and the peg lifting motor M2 is rotated in the forward direction (at the same time, the peg rotation motor M1 is wound for a predetermined time). The slide plate 191 ascends together with the elevating body 53 and rises to rotate the slide plate 191.
The Shino guide member 196 of the Shino hanging bar 194 attached to
Ascend to the position shown in the figure. Shino guide member
Since the 196 is arranged above the main body 131 of the Shinobu head 130, the Shinobu of the full bobbin 1 has a corresponding guide recess of the Shino guide member 196 while the Shinotsu head 130 swings from the standby position to the Shino joint position. The shino of the full bobbin is already in the state of being hooked on the shino guide member 196 at (the position of) the shino connecting position, which is guided by the 196a. Therefore, when rising from the position to the position, the shino of the full bobbin rises while hanging on the shino guide member 196, and when reaching the position of the rising end, the shino guide member 196 moves the roving guide 10 and the small ball bobbin in front. Between the 2nd floor, the full bobbin Shino is lifted above the anchor-shaped hook of the roving guide 10. On the other hand, at this time 2
1 full bobbin 1 is the original bobbin hanger 15 on the spare rail 13
It is mounted on the peg 42 while being inserted into the. Next, when the air cylinder 188 for swinging the sash bar is operated and its piston rod 189 projects, the slide bar 181 swings forward, and the sash bar 194 also swings integrally with the slide bar 181. 196 moves from the position of to the position between the roving guide 10 and the rear small bobbin 2B. Since the slide bar 181 swings following the cam groove 183 of the cam plate 184, the shino guide member 196 swings substantially straight forward to above the hook piece of the roving guide 10 and passes above the hook piece of the roving guide 10. After doing, move to the right while moving forward. Therefore, in the plan view of FIG. 13, when the shino of the left full bobbin 1 exceeds above the hook piece of the roving guide 10, the shino of the downstream portion of the shino guide member 196 engages with the hook piece and moves backward. Since it is guided, it hooks on the hook piece of the roving guide 10 and the full bobbin on the right side is
When the downstream portion of the riving guide 10 reaches the position passing the left side of the hook piece of the roving guide 10, the shino of the upstream portion of the shino guide member 196 is vertically opposed to the hook piece (Fig. 13 (C)). ). Next, when the motor M2 for raising and lowering the peg is reversely rotated to lower the lifting body 53, the two full bobbins 1 are suspended by the bobbin hanger 15 of the spare rail 13, and the slide plate 191 is lowered together with the lifting body 53. As a result, the shino guide member 196 also descends (during the descent (the position shown in FIG. 9), the shino hanging bar swinging air cylinder 188 is operated to retract the piston rod 189 to move the shino guide member 196 into FIG. 9). Return to the position of.
The shinobi of the full bobbin 1 hung on the spare rail 13 is roving because the shinobi of the full bobbin hanging on the shino guide member 196 is entrusted to the hook piece of the roving guide 10 while the shino guide member 196 descends →→. Spinned on the guide 10. Thus, when the shining of the two roving guides 10 is applied to the shining of the two full bobbins 1, the shining of the left full bobbin is wound around the hook piece of the left roving guide as shown in FIG. 13 (d). The state is that the full bobbin on the right side simply hangs on the hook piece of the roving guide on the right side. Therefore, the small bobbin 2B on the rear side of the left full bobbin 1 in the state in which one winding is wound around the hook piece of the roving guide by the Shino exchange machine which runs along the machine base after the Shino Tsume machine of the present invention performs Shino Tsume and Shino hanging Replacing with, the full bobbin 1 passes between the roving guides 10 on both sides and is hung on the bobbin hanger 12 on the rear row of the creel, so the full bobbin shining on the bobbin hanger 12 on the rear side also roves. It is in a normal spinning state where it is simply hooked on the hook piece of the guide 10. Shino guide member 196
After returning to the position of, the air cylinder for swinging the Shinobu head
The piston rod 158 of 157 is projected to return the Shino joint head 130 to the standby position, and the Shino gripping lever 134, which was at the neutral position, is returned to the position where it abuts on the nip piece 143. In the shining device 180 of the above embodiment, instead of moving the slide bar 181 laterally by the cam mechanism shown in FIG. 12, for example, a lateral moving air cylinder is attached to the hinoki joint head support arm 151 and the slide bar 181 is placed. It is configured to move laterally by a fixed amount, and after moving backward from the position shown in FIG. 9 of the above embodiment, it is moved laterally to the right by the lateral movement air cylinder and moved to the rear position of the roving guide 10. Next, return to the front, then move to the left and return to. That is, the Shino guide member 196 →
Even if it is moved to →, Shino of the full bobbin 1 which was guided by the Shino guide member 196 while being moved from to is deposited on the hook piece of the roving guide 10 and the same Shino hanging can be performed. .

Thus, the Shinotsugi work of one unit cycle is completed, and Shinotsuki 3
Moves laterally to a position corresponding to the next pair of front and rear small bobbins 2F, 2B, and repeats the above-mentioned joining work from one end of the spinning machine to the other end.

In the above embodiment, the bobbin hanger 15 for the spare rail is used.
Place the full bobbin 1 that is suspended on the peg 42 of the full bobbin supporting head 40, perform the sashing work at the standby position of the full bobbin supporting head 40, and then return the shunted full bobbin to the spare rail. However, a spare rail may be provided at an appropriate position in front of the creel, and a full bobbin may be suspended on a freely rotatable bobbin hanger to perform the splicing work. In this case, since the peg 42 of the full bobbin supporting head 40 only needs to rotate the full bobbin in the rewinding direction, it is not necessary to place the full bobbin on the peg. Further, the Shino end pull-out device 40 may be provided on the main body of the Shino-joint machine so as to be able to move up and down, and the pick-up member 89 may be opposed to the full bobbin suspended on the spare rail to perform the Shino-end draw-out. Further, in the above embodiment, the shining device 180 also serves as the lifting device for the full bobbin supporting head 40 to raise the shining guide member 196 and the joining bobbin at the same time. It goes without saying that the device may be configured to move up and down. In any case, the present invention connects the full bobbin shino to the shino from a pair of front and rear small bobbins that are suspended and spun on a creel, and the full bobbin shino hanging from the spare rail is a roving guide. It achieves its purpose by making it spin.
