Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention prepares a peg tray having an empty bobbin inserted in advance on a conveyor which is arranged below a spindle row of a spinning machine in parallel with a spindle rail. After the stand was completely filled,
A tube that takes in an empty bobbin together with a peg tray from the conveyor into the pipe changer, replaces a plurality of empty bobbins on the spindle with empty bobbins on the peg tray at the same time, and returns the peg tray with the full bobbin inserted to the conveyor. The present invention relates to a tube replacement method in a spinning machine that uses a replacement machine to perform tube replacement.

[Prior Art] In a spinning machine such as a ring spinning machine and a ring twisting machine, a full bobbin on a spindle and an empty bobbin prepared in advance on a conveyor provided below a spindle rail are automatically automatically stopped after the machine stand is fully loaded. A pipe changer of a type that moves along a spinning machine stand has been proposed and used as a pipe changer for replacement.
Conventionally, this type of pipe changer is disclosed, for example, in Japanese Patent Publication No. 56-8136.
As in the device disclosed in Japanese Patent Laid-Open No. 60-246828, an empty bobbin is preliminarily attached to a peg of a conveyor arranged below a spindle rail, and is prepared at the time of pipe change due to a full pipe stop. The pipe changer moves along the spindle rail, pulls out the full bobbin on the spindle, pulls out the empty bobbin from the peg, and inserts the full bobbin pulled out from the spindle into the peg after the empty bobbin is pulled up. At the same time, the empty bobbin pulled out from the peg is inserted into the spindle after the full bobbin is pulled out.

On the other hand, in recent years, in a spinning factory, it is considered to further reduce the labor by going one step further from the automation of each process and connecting a plurality of processes with an automatic conveying means. Then, by connecting the spinning process and the winder process with a transport path, the full bobbin fried in the spinning machine is transported to the winder process, and the empty bobbin used in the winder process is transported to the spinning process. Reusable methods have been proposed and implemented. In this way, when carrying out the full bobbin and empty bobbin transport by directly connecting the spinning process and the winder process by the transport path,
For example, as disclosed in Japanese Unexamined Patent Publication No. 60-52475, a transport method using a peg tray having a peg projecting on its upper surface has a mechanism that is more efficient than a method using a belt conveyor having a peg projecting. It is attracting attention because it is easy.

However, there is a problem in that a conveyor for carrying a bobbin using a peg tray is provided below the spindle rail and the pipe changing operation is automatically performed using the conventional pipe changing device. That is, in order for the conventional automatic pipe changer to smoothly perform the pipe change work, the empty bobbins prepared in advance below the spindle rail must be arranged at the same predetermined interval as the spindle pitch. However, in recent years, spinning machines such as spinning machines and twisting machines have become more and more spindles, and it is not uncommon to use a spinning machine with 400 spindles on each side. However, there is a problem in that the pitch of the peg tray is very strictly manufactured and a means for arranging the peg tray at a predetermined pitch is required. In addition, in the conventional configuration of the pipe changer, the transfer time of the empty bobbin or the full bobbin between the peg and the spindle on the conveyor during the replacement work of the empty bobbin and the full bobbin becomes a large proportion of the entire pipe change time. As a result, there is a problem that the pipe replacement work time is prolonged, the machine standstill time is lengthened, and the operating efficiency of the spinning machine stand is reduced.

In order to solve the above-mentioned problems, the applicant of the present invention previously prepared a peg tray having an empty bobbin inserted on a conveyor arranged below the spindle row of the spinning machine in parallel with the spindle rail, and fully prepared the spinning machine table. After stopping the pipe, run the pipe changer along the spindle rail from one end of the machine base, take the empty bobbin together with the peg tray into the pipe changer from the conveyor, and remove the empty bobbin from the peg of the peg tray in the pipe changer. Insert the empty bobbin into the spindle with the full bobbin pulled out, insert the full bobbin pulled out from the spindle into the peg of the peg tray with the empty bobbin removed, and return the peg tray with the full bobbin inserted to the conveyor. Proposed a replacement method (Japanese Patent Application No. 62-1095).
No. 40).

[Problems to be Solved by the Invention] However, in a pipe changing machine that takes the empty bobbin together with the peg tray into the pipe changing machine, the empty bobbin is removed from the peg tray taken into the pipe changing machine, and the spindle with the full bobbin pulled up. Before the empty bobbin removing / inserting device that inserts the empty bobbin into the spindle reaches the position corresponding to the spindle,
Since it is necessary to take in the peg tray in which the empty bobbin is inserted from the belt conveyor into the pipe changer, the relationship between the peg tray in which the empty bobbin is inserted and which is previously arranged on the belt conveyor and the spindle is shown in FIG. Thus, it is necessary to dispose the ends so that they are displaced. However, depending on the spinning machine, as shown in Fig. 7, the out-end
Some OE and gear end GE have a wide range. When the widths of the out-end OE and the gear end GE are wide as described above, it is difficult to apply the above pipe replacement method because the both ends of the conveyor that conveys the peg tray cannot be made sufficiently longer than the both ends of the spindle row. There's a problem.

The present invention has been made in view of the above problems, and an object thereof is to load an empty bobbin with a peg tray even if the length of the conveyor arranged below the spindle row of the spinning machine is not much longer than the length of the spindle row. An object of the present invention is to provide a pipe changing method in a spinning machine, which can smoothly perform the pipe changing by the pipe changing machine which takes the whole pipe into the pipe changing machine.

[Means for Solving the Problems] In order to achieve the above object, in the present invention, the pipe changer is arranged on a conveyor in which the peg tray intake is arranged below the spindle row and in parallel with the spindle rail. While stopped at a position corresponding to one end of the peg tray row, drive the conveyor in the direction in which the peg tray row approaches the pipe changer, take in a predetermined number of peg trays into the pipe changer, stop the conveyor, and then change the pipe changer. Perform a pipe replacement work by sequentially moving the full bobbin on the spindle and the empty bobbin on the conveyor by running along the spindle rail, and after inserting the empty bobbin on the last spindle of the spindle row, stop the travel of the pipe changer, Drive the conveyor in the direction in which the row of peg trays moves away from the pipe changer, and the peg trays with the full bobbin inserted into the pipe changer are sequentially conveyed. I tried to hand it over.

The full bobbin F is conveyed to a position corresponding to and above the full bobbin F and the peg tray 12 from which the empty bobbin E has been removed is conveyed to almost the same height as the lower part of the spindle 11, and the full bobbin F is inserted at that position. A twisting / conveying device 15 for conveying the formed peg tray to the peg tray delivery device 14 is provided.

The twisting / conveying device 15 has a portion in which the traveling path of the belt 16 for transferring the peg tray 12 runs substantially parallel to the tray guide 9 and a portion that runs parallel to the lower part of the spindle 11 in parallel. A motor 18 that is wound around a large number of guide pulleys 17 so as to have a portion that runs parallel to the spindle rail 8 above the full bobbin F that is inserted on the motor 11 and that is disposed in the lower center of the machine base. It is wound around a drive pulley 19 fitted to the drive shaft of No. 2 and is driven so that the portion traveling in parallel with the tray guide 9 is the same as the traveling direction during pipe change of the pipe changer 1. Further, a pair of linear guide members 20 are arranged along the traveling path of the belt 16 so as to sandwich the peg 12a of the peg tray 12 and to press the peg tray 12 toward the belt 16 side. That is, this twisting and conveying device 15 is disclosed in Japanese Unexamined Patent Publication No. 62-180882.
The same effect as the device disclosed in the publication is exhibited, and the peg tray 12 is held in a state of being pressed against the belt 16 by the guide member 20, and the belt 16 is driven in this state to move the peg tray 12 to the belt 16. It is to be moved with. By disposing the guide member 20 in a twisted state with respect to the belt 16, the posture of the empty bobbin E or the full bobbin F on which the peg tray 12 is mounted can be freely changed.

On the rear wall side of the pipe changer 1, a traveling body 21 is supported by support shafts 22 and 23 so as to be slidable in the traveling direction of the pipe changer 1. The empty bobbin E conveyed upward is removed from the peg tray 12, and the empty bobbin extracting / inserting device 24 for inserting the empty bobbin E into the spindle 11 from which the full bobbin F has been lifted up, and the full bobbin F is pulled out from the spindle 11.

The traveling body 21 is reciprocally moved by a cam lever 27 that is reciprocally swung via a cam 26 operatively connected to the screw roller 7, and a supporting arm 28 of the empty bobbin removing / inserting device 24 and a supporting arm of the full bobbin removing / inserting device 25. 29 is also operatively connected to the screw roller 7 via a gear mechanism and a cam mechanism (not shown). The empty bobbin removing / inserting device 24 and the full bobbin removing / inserting device 25 are driven in synchronization with the reciprocating movement of the traveling body 21, and the traveling body 21 is pulled up by the full bobbin removing / inserting device 25 and When the empty bobbin removing / inserting device 24 inserts the empty bobbin into the spindle 11, the positional relationship between both devices and the corresponding spindle 11 is kept constant. That is, the empty bobbin extracting / inserting device 24 is installed in the pipe changer 1 from above the belt conveyor 10 and
Peg tray 12 with an empty bobbin that has been transported above 11.
The empty bobbin E is removed from the peg tray 12 in a state where four are aligned at a predetermined position by the action of the peg tray restricting piece 30, and the full bobbin F is inserted into the spindle 11 after being pulled out. After the empty bobbin E is taken out, the full bobbin F is inserted into the four peg trays 12 aligned by the action of the peg tray restricting pieces 31 at substantially the same height as the spindle 11.

As shown in FIG. 1, the spinning machine SF in this embodiment has a belt 10a of a belt conveyor 10 extending between an out end OE and a gear end GE of the spinning machine SF as shown in FIGS. 4 (a) and 4 (b).
As shown in FIG. 3, the frame 32 is rotatably supported via a bearing 33, and is provided between the driven pulleys 35 and 36 provided with an engaging recess 34 having teeth on its peripheral surface on the side corresponding to the pipe changer 1. It is wrapped around. The pipe changer 1 has a cylinder 37 in the lower center.
Is equipped with a support bracket 38 that is moved to a position approaching the belt conveyor 10 and a position separating it from the belt conveyor 10, and the drive shaft of the motor 39 fixed on the support bracket 38 is engaged with the recesses of the driven pulleys 35 and 36. A bevel gear 40 meshing with the gear 34 is fitted and fixed.

Next, a pipe replacement method using the apparatus configured as described above will be described. Prior to the pipe replacement, the peg tray 12 in which the empty bobbin E is inserted is arranged on the belt conveyor 10 in a state corresponding to the spindle row. When the spinning machine SF is fully stopped in this state, empty bobbins E and full bobbins F as shown in Fig. 1 (a).
And correspond to each other. Next, the pipe changer 1 is moved from the standby position, and the peg tray intake port in which the peg tray intake device 13 is arranged is stopped at a position corresponding to the end of the row of peg trays 12. At this stop position the belt conveyor 10

In this state, the cylinder 37 is operated and the bevel gear 40 is meshed with the engagement recess 34. Then, the motor 39 is driven and the belt conveyor 10 is driven in the direction in which the peg tray 12 row approaches the pipe changer 1. Further, the motor 18 of the twist conveying device 15 is driven at the same time as the driving of the motor 39. As a result, the peg tray 12 is sequentially taken into the pipe changer 1 together with the empty bobbin E by the action of the peg tray taking-in device 13, and is conveyed to a predetermined position by the twisting and conveying device 15. A certain number of peg trays 12 are pipe changer 1
The motor 39 is stopped and the cylinder 37 is actuated when it is taken into the inside, the bevel gear 40 and the driven pulley 35 are released from the engagement, and the belt conveyor 10 is stopped, as shown in FIG. 1 (b). It becomes a state. From this state, the pipe changer 1 starts traveling along the spindle rail, and the operations of the empty bobbin removing / inserting device 24 and the full bobbin removing / inserting device 25 are started. As a result, when the empty bobbin removing / inserting device 24 performs the operation of removing the empty bobbin E, the peg tray 12 that has been taken into the tube changer 1 before the traveling of the tube changer 1 is moved to the predetermined position corresponding to the full bobbin F. It will be placed. Then, the pipe changer 1 continuously runs along the spindle rail 8, and the full bobbin F on the spindle 11 and the empty bobbin E on the belt conveyor 10 are moved.

Move to the side. The full bobbin F is inserted because it takes a predetermined transport time by the twist transport device 15 until the full bobbin F pulled out from the spindle 11 is delivered to the belt conveyor 10 via the peg tray delivery device 14. The peg tray 12 is not arranged at a position corresponding to the spindle from which the full bobbin is pulled out, but is arranged at a position displaced in the advancing direction of the pipe changer 1 as shown in FIG. 1 (c). After the pipe changer 1 inserts the empty bobbin E into the spindle at the end of the spindle array on the out end OE side, the bevel gear 40 moves the driven pulley.
The pipe changer 1 is stopped at a position facing 36, and the state shown in FIG. In this state, the four full bobbins F finally pulled out from the spindle 11 are in the pipe changer 1. In this state, the cylinder 37 is operated and the bevel gear 40 moves the driven pulley.
After the engagement with the engagement recess 34 of 36, the motor 39 is driven to drive the belt conveyor 10 in the direction in which the row of peg trays 12 is separated from the pipe changer 1. As a result, a space for delivering the peg tray 12 is created on the belt conveyor 10 corresponding to the peg tray delivery device 14 of the pipe changer 1, and the peg tray 12 in which the full bobbin F taken into the pipe changer 1 is inserted is sequentially formed. It is delivered on the belt conveyor 10. Then, the peg tray 12 in which all the full bobbins F are inserted is the belt conveyor.
The drive of the motor 39 and the drive pulley 19 is stopped when the peg tray 12 with the full bobbin F is inserted into the empty bobbin E inserted into the spindle 11 as shown in FIG. 1 (e). It is placed in the corresponding state and the pipe replacement work is completed. After that, the pipe changer 1 moves to the original position as shown in FIG. 1 (f).

The present invention is not limited to the above-mentioned embodiment, and for example, as shown in FIG. 5, a belt conveyor 10 equipped with a motor 41 is used, and a pipe changer at the start and end of pipe replacement is used. The motor 41 may be driven by transmitting and receiving a signal to and from 1. Further, the method of the present invention may be applied to a spinning machine having narrow out-end OE and gear-end GE.

[Effects of the Invention] As described in detail above, according to the present invention, even if the length of the conveyor disposed below the spindle row is substantially the same as the length of the spindle rail, the empty bobbin can be moved from above the conveyor to the peg tray. In addition, it is possible to use a pipe changer that takes it into the pipe changer and performs pipe changing work while running continuously, and also uses a peg tray to transfer bobbins to an existing spinning frame with wide out-ends and gear ends. It becomes easy to apply the carrying means for carrying out.
