2. Description of the Related Art Generally, in a spinning machine such as a ring spinning machine and a ring twisting machine, in order to facilitate the automatic pipe replacement work by the pipe replacement device when the pipe replacement work is accompanied by a full pipe, a spindle pitch is set along a spindle rail. It is necessary to supply the empty bobbin in a corresponding state and to carry out the full bobbin that has been fried. As a conveyor of this type, there is a belt conveyor in which an endless steel belt in which pegs are planted at intervals equal to the spindle pitch is wound around a drive pulley and a driven pulley. Then, an auxiliary conveyor and a picker that engages with the bottom of the full bobbin mounted on the peg and pushes up the bobbin are arranged on the first end side (out-end side) of the belt conveyor. The full bobbin pulled out from the peg was carried out to the full bobbin storage box by the auxiliary conveyor. Further, an empty bobbin supplying device is also disposed on the first end side of the belt conveyor to supply the empty bobbin to the peg from the empty bobbin supplying device (for example, the actual open shovel 5
6-3165, etc.). However, with belt conveyors that use steel belts, the belt stretches over a long period of time, and the stretch gradually increases, and the peg pitch does not correspond to the spindle pitch, hindering pipe replacement work. It becomes a state.

As a device for solving this inconvenience, Japanese Unexamined Patent Publication No. Sho.
Japanese Patent Publication No. 7-161133 discloses a guide rail that includes a portion extending along the longitudinal direction of the spinning machine base, a portion extending in a direction orthogonal to the longitudinal direction, and an arc-shaped portion connecting the two parts under the spinning machine base. And a peg tray is arranged on the guide rail. In this device, the peg trays are placed on the guide rails in a state of abutting each other, and the drive device having the locking claws that engage with the locking recesses formed on the lower surface of the peg tray is the longitudinal direction of the spinning machine stand of the guide rails. It is arranged in a portion extending along the direction. Then, the peg tray is intermittently moved by the amount corresponding to the pitch of the spindle by the reciprocating movement of the locking claws. In addition, in the part of the guide rail orthogonal to the spinning machine stand, there is a full tube discharge device that removes the full bobbin mounted on the peg tray, and an empty bobbin supply device that supplies the empty bobbin to the peg tray from which the full bobbin has been removed. It is set up. Then, after the doffing with the full pipe is completed, the full bobbin is pulled out from the peg tray and the empty bobbin is mounted while the peg tray goes around the guide rail by the operation of the drive device, and the empty bobbin is placed at a position corresponding to the spindle. It has become so.

Further, Japanese Patent Application Laid-Open No. 4-214428 discloses that
At the end of a plurality of spinning machine bases, a conveyor for transporting the peg tray is arranged so that the peg tray can be transferred between the conveyors mounted on the machine frame in a state orthogonal to the longitudinal direction, It is disclosed that a bobbin carrying device and an empty bobbin supplying device are provided at the ends. In this device, the peg tray in which the full bobbin fried from the spinning machine stand has been inserted is carried out onto the full bobbin carrying path of the carrying conveyor, and is carried to the end of the spinning machine group by the carrying conveyor. ,
It is transferred to the bobbin transport device at that position, transferred to the bobbin container placement position, and discharged into the bobbin container. The peg tray from which the full bobbin has separated is conveyed to a position below the empty bobbin supply section of the empty bobbin supply device, and after the empty bobbin is inserted into the peg at that position, it is transferred onto the empty bobbin transfer path of the transfer conveyor. . Then, the empty bobbin is again delivered to the transport device mounted on the spinning machine base.

Problems to be Solved by the Invention JP-A-57-1611
In the apparatus disclosed in Japanese Patent No. 33, the peg trays arranged on the guide rails arranged around the spinning machine stand are always moved so as to be in contact with each other. Further, the full pipe discharging device is fixed at a predetermined position, and while the peg tray is stopped, the upper part of the full bobbin is grasped and the full bobbins are pulled out one by one from the peg tray. Therefore, when the peg tray is moved, it is necessary to stop the peg tray with the full bobbin attached at a position corresponding to the full tube discharge device and confirm that the full bobbin has been pulled out before moving the peg tray. As a result, carrying out full bobbins fried on the peg tray,
It takes time to finish supplying empty bobbins to the peg tray. Even if it takes time to complete the supply of the empty bobbin, it may be completed before the next doffing of the spinning machine. Therefore, in the case of an ordinary spinning frame with about 400 spindles, there is no problem. However, when the number of spindles is, for example, about 900 spindles, when spinning a thick yarn, the time from the start of full bobbin delivery to the completion of empty bobbin supply is longer than the doffing cycle. There are cases. in this case,
It is necessary to wait until the supply of the empty bobbin is completed in the state where the pipes are fully stopped, which causes a problem that the operating rate of the machine base is lowered.

Further, in the apparatus disclosed in Japanese Patent Laid-Open No. 4-214428, a plurality of conveyors for transporting are provided at the end of the spinning machine stand so as to be orthogonal to the longitudinal direction of the spinning machine stand. It is necessary to set the time for carrying out full bobbins and the time for carrying in empty bobbins so that they do not overlap with other spinning machine bases, which reduces the degree of freedom in setting the pipe replacement time. or,
Since it is necessary to control the moving direction of the peg tray by providing a point at the connecting portion between the conveyor for transportation and the transportation device of each spinning machine stand, the control becomes complicated.

Further, as in the apparatus disclosed in Japanese Patent Laid-Open No. 4-214428, peg trays on the conveyors disposed on both the left and right sides of the spinning machine stand are connected from one conveyor to the other via connection rails. In the configuration in which the peg tray is moved to the transport device, the peg trays are generally placed in one row on the connection rail. Therefore, when a full bobbin is inserted into the peg tray on the transfer device during pipe replacement, a peg tray group in which an empty bobbin is inserted between the peg tray groups in which the full bobbin on both transfer devices is inserted. It becomes a state that exists. Conventionally, when unloading a full bobbin, the peg tray in which an empty bobbin has been inserted is also emptied without distinction, and the empty bobbin is mixed in the bobbin storage container, resulting in a full bobbin and empty bobbin during the winder process. It took a lot of time to sort out the bobbins.

While the peg tray 2 passes through the position corresponding to the belt conveyor 20, the full bobbin F or the empty bobbin E inserted into the peg tray 2 is pressed against the belt 30 via the pressing plate 34 by the action of the torsion spring. Then, the bobbin is pulled out from the peg 2b by the frictional force with the belt 30 and is carried into the bobbin storage container 50.

That is, while the full bobbin F or the empty bobbin E is inserted, the bobbin is automatically removed from the peg 2b while passing through the position corresponding to the belt conveyor 20. Further, the bobbin removing operation has nothing to do with the operation timing of both the transport devices T1 and T2. If a belt having a large frictional resistance is used as the belt 30, the bobbin can be removed without the pressing plate 34, but the bobbin is pressed against the belt 30 by the pressing plate 34, so that the bobbin can be reliably removed. Further, in this embodiment, since the tip of the pressing plate 34 is bent upward, the bobbin mounted on the peg tray 2 is full bobbin F.
Whether it is the empty bobbin E or the pressing plate 3
4 enters below and is pressed against the belt 30 side.

The peg tray 2 fed from the transfer device T2 is not limited to the full bobbin F inserted, but may be the empty bobbin E inserted. In this apparatus, the empty bobbin E as well as the full bobbin F is accommodated in the bobbin accommodating container 50 and sent to the winder process, for example. However, since the winder has a device for selecting the empty bobbin E and the full bobbin F, there is no problem.

The posture of the peg tray 2 from which the full bobbin F or the empty bobbin E has been removed is changed so that the peg 2b becomes substantially vertical while moving to the position corresponding to the empty bobbin supplying device 21, and the empty bobbin is moved. It moves to a position corresponding to the front end of the supply unit 39. The feeding device 49 is always the engaging arm 48a.
Is arranged at the engagement position shown by the solid line in FIG. 3, and the peg tray 2 stops with the locking portion 2c engaged with the empty bobbin E located at the front end of the empty bobbin supply portion 39. When the sensor S3 detects the peg tray 2, the air cylinder 47 is operated based on the detection signal and the lever 48 is swung. Then, as the lever 48 swings, the engagement arm 48b comes into a state of engaging with the peg tray 2, and the peg tray 2 is moved to the front side by a predetermined amount. At this time, the empty bobbin E engaged with the locking portion 2c is moved to the front side against the urging force of the regulation member 45, and the engagement with the regulation member 45 is released to the peg 2b. It is inserted. And empty bobbin E
The peg tray 2 in which is attached moves to the first end of the first transport device T1.

When the empty bobbin E is unloaded from the empty bobbin supply unit 39 and the two bobbin detection sensors S1 and S2 are not detecting bobbins, the drum 41 is rotated by a predetermined amount to form one empty bobbin. E is sent out from the empty bobbin storage box 37, and the empty bobbin supply section 39 is replenished with the empty bobbin E.

In the same manner, the peg tray 2 with the bobbin inserted therein is sequentially sent from the second transfer device T2 to the bobbin transfer device 14, and while passing through the bobbin transfer device 14, the bobbin is removed from the peg 2b. Then, the empty bobbin E is inserted and returned to the first transport device T1. Then, when the peg tray 2 having the empty bobbins E inserted therein is arranged at a position corresponding to the spindle rows on both sides of the spinning machine base 1, the bobbin carry-out / supply work is completed. Then, the bobbin accommodating container 50 is carried by the operator to the next step by the carrier 51. The empty bobbin E is supplied to the empty bobbin storage box 37 of the empty bobbin supply device 21 when the worker transports the bobbin storage container 50 from the next process by the carrier 51. The bobbin E is stored and transported, and the bobbin E is moved from the inside of the bobbin storage container 50.

As described above, the peg tray 2 carried out from the second transfer device T2 is passed through the bobbin transfer device 14 to be the first.
While being returned to the transport device T1 of
The full bobbin F is detached from the peg 2b and the empty bobbin E is supplied to the peg 2b regardless of the operation timing of the. Therefore, the processing capacity is improved and the control is simplified.

In addition to the above effects, this embodiment has the following effects. (A) Since the belt conveyor 20 for carrying out the full bobbin F constitutes a part of the bobbin extracting means, the structure is simplified.

(B) At the lower end of the belt conveyor 20,
Pressing plate 34 whose tip side is bent upward
However, up to the center of the width of the belt 30, the belt 30 is supported by a torsion spring so that the distance between the belt 30 and the belt 30 is substantially smaller than the outer diameter of the empty bobbin E and is substantially parallel to the belt 30. There is. Therefore, the full bobbin F or the empty bobbin E inserted in the peg tray 2 is reliably pulled out from the peg 2b and transferred onto the belt conveyor 20.

(C) Since the engaging portion 2c is formed at the tip of the peg 2b, the peg tray 2 is engaged with the bottom portion of the empty bobbin E while moving to easily move the empty bobbin E to the front side. Become.

(D) Since the peg tray 2 engaged with the empty bobbin E is positively pushed and moved by the feeding device 49, the empty bobbin E reliably moves to the front side against the biasing force of the regulating member 45. Then, it is attached to the peg 2b. Therefore, it becomes easy to adjust the frictional force of the belt 17 for moving the peg tray 2 with respect to the peg tray 2 and the urging force of the regulating member 45.

(Second Embodiment) Next, a second embodiment will be described with reference to FIGS. In this embodiment, the empty bobbin E extracted from the peg tray 2 is selected and discharged from the belt conveyor 20 before being carried into the bobbin storage container 50 by the belt conveyor 20, and the bobbin in which the full bobbin F is stored. Empty bobbin E into the container 50
The present embodiment is different from the above embodiment in that it is configured so as to avoid the mixture of The configuration of the belt conveyor 20 is slightly different, and a bobbin identifying means and a bobbin discharging means are provided in the middle of the belt conveyor 20, which is different from the above embodiment, and the other configurations are the same.
The same parts are designated by the same reference numerals, and detailed description will be omitted.

As shown in FIG. 7, the belt conveyor 20 is formed longer than that of the above-mentioned embodiment and is arranged so that the inclination thereof is gentle. Further, instead of providing the pressing plate 34, the extracting member 52 is provided at a position corresponding to the lower portion of the belt conveyor 20 of the bobbin transfer device 14.
Is provided. As shown in FIG. 9, the extraction member 52
Is formed in a wedge shape and engages with the bottom of a full bobbin F, an empty bobbin E, etc. inserted into the peg tray 2 passing through the position corresponding to the belt conveyor 20, and moves the bobbin as the peg tray 2 moves. The peg 2b is moved in a direction away from the peg 2b.

As shown in FIG. 7, the support plate 26a has an opening 53 formed above the notch 33 and slightly longer than the length of the empty bobbin E. Notch 33 and opening 5
Two sensors SS that constitute bobbin identification means between
1, SS2 are provided. Both sensors SS1 and SS2 are non-contact type transmissive optical sensors.
As shown in, the light projecting portions SS1a and SS2a are attached to the support plate 2
The light receiving portions SS1b and SS2b are fixed to the support plate 26b at 6a, and are arranged so as to face each other with the bobbin passing region in between. The first sensor SS1 is arranged at a position where the empty bobbin E moving on the belt conveyor 20 can be detected, and the second sensor SS2 is arranged at a position where the bobbin winding being detected by the first sensor SS1 can be detected. It is arranged. In this embodiment, both sensors SS1 and SS2 are arranged side by side vertically, and the second sensor SS2 has a distance from the belt 30 where the light projected by the light projecting portion SS2a is slightly larger than the diameter of the base end of the empty bobbin E. Positioned to pass through the position. That is,
When the empty bobbin E passes a position corresponding to both sensors SS1 and SS2, only the first sensor SS1 outputs a detection signal,
When a bobbin (tubular yarn) such as a full bobbin F on which a yarn is wound passes, both sensors SS1 and SS2 output detection signals.

An air nozzle 54 as a bobbin discharging means is arranged at a position facing the opening 53 on the support plate 26b. The air nozzle 54 transfers the compressed air to the belt 30.
It is arranged at a position orthogonal to the traveling direction of No. 1 and capable of injecting toward the empty bobbin E moving together with the belt 30. The air nozzle 54 is connected to a compressed air source (not shown) via a pipe 55, and the air nozzle 54 is provided in the middle of the pipe.
A solenoid valve 56 is provided to control the supply of compressed air to the. The solenoid valve 56 changes from the state in which the bobbin detection signal is output only from the first sensor SS1 to the first sensor SS1.
When the bobbin detection signal from is turned off, the solenoid valve 56
The opening / closing is controlled by a control device (not shown) that outputs an open signal to the.

In this embodiment, before the bobbin carrying-out / supplying work is started, the bobbin storage container 50 is placed under the belt conveyor 20 while being placed on the transport carriage 51, and the empty bobbin storage is carried out. The container 57 is arranged below the opening 53. When the bobbin carrying-out / supplying work is started from that state, the peg tray 2 carried out from the second carrying device T2 to the bobbin carrying device 14 is located at a position corresponding to the belt conveyor 20 in the same manner as in the above-described embodiment. And is returned to the first transport device T1. When the peg tray 2 passes through a position corresponding to the belt conveyor 20, the bobbin inserted into the peg 2b tilts so as to be parallel to the belt 30, and the extracting member 52 engages with the bottom of the bobbin. To meet. Then, while the peg tray 2 passes through the position corresponding to the belt conveyor 20, the bottom of the bobbin is moved along the engaging surface 52a of the extracting member 52 in the direction of separating from the peg 2b, so that the belt 30 is moved. Reprinted in. Therefore, as compared with the case where the pressing plate 34 is provided, when the tubular thread is pulled out from the peg 2b, the thread is less likely to be damaged.

Belt 3 pulled out from peg tray 2
The bobbin transferred above 0 is conveyed upward as the belt 30 travels. And the bobbin has both sensors SS1 and SS2
When passing the position corresponding to, it is identified whether the bobbin is the full bobbin F or other tubular thread or the empty bobbin E. In the case where the bobbin is a full bobbin F or a yarn near the full bobbin F, as shown in FIG. 10A, the bobbin is extra by the thickness of the winding layer YL as compared with the case of the empty bobbin E. Then, the belt 30 is separated from the belt 30. As a result, both sensors SS
1 and SS2 always correspond to the bobbin, and the ON signals are continuously output from both sensors SS1 and SS2. or,
In the case where the bobbin is a tube thread in which the thread is wound only on a part thereof, as shown in FIG. 10 (b), the bobbin is inclined with the end portion on the side remote from the winding layer contacting the belt 30. It becomes a state. Therefore, the first sensor SS1 is always in the state corresponding to the bobbin and continuously outputs the ON signal, and the second sensor SS1
SS2 temporarily becomes a state corresponding to the bobbin and outputs an ON signal at that time.

On the other hand, when the bobbin is the empty bobbin E, while the bobbin passes through the positions corresponding to both sensors SS1 and SS2,
The ON signal is continuously output from only the first sensor SS1. That is, the ON signal is continuously output from only the first sensor SS1 only when the empty bobbin E passes through the positions corresponding to both the sensors SS1 and SS2.

Then, after the ON signal is continuously output only from the first sensor SS1, a predetermined time after the output signal is turned OFF, the control device outputs an opening signal to the solenoid valve 56 for a predetermined time. Then, the compressed air is ejected from the air nozzle 54. This predetermined time is set to the time after the end of the empty bobbin E has passed the positions corresponding to both sensors SS1 and SS2 and until the entire empty bobbin E is in a state substantially corresponding to the opening 53. Therefore, the empty bobbin E has the opening 5
3, the compressed air is injected from the air nozzle 54 at a position opposite to the position 3, and the compressed air causes the compressed air to roll in a direction substantially orthogonal to the traveling direction of the belt 30 and is discharged from the opening 53. To fall. The yarns other than the empty bobbin E are accommodated in the bobbin accommodating container 50 without receiving the compressed air jet from the air nozzle 54. The empty bobbin E accommodated in the empty bobbin accommodating container 57 is transferred to the empty bobbin accommodating box 37 by an operator.

Since a device for selecting empty bobbins is provided in the winder process, the operation of the winder itself is not hindered even if the empty bobbins E are mixed. However, since the number of empty bobbins E carried out from one spinning frame 1 during one bobbin carrying-out / supplying operation is a considerable number, when the empty bobbins E are selected on the winder process side. Take the trouble.
In addition, extra energy is required to transport the empty bobbin E, which is unnecessary in the winder process, between the spinning frame 1 and the winder process. However, in this embodiment, since the empty bobbin E of the bobbins taken out from the peg tray 2 is discharged from the belt conveyor 20 during the conveyance by the belt conveyor 20, the yarn is conveyed to the next step (for example, the winder step). The empty bobbin does not mix in the bobbin housing container 50. As a result, the above inconvenience is eliminated.

Further, since the empty bobbin E is discharged by the injection of compressed air, the structure is compared with the case where the empty bobbin E is discharged by using the pushing plate or the like which is reciprocally moved by the driving means such as the cylinder. Will be easier. Further, even if the distance from the succeeding bobbin is short, there is no possibility that the pushing plate or the like interferes with the succeeding bobbin.

The present invention is not limited to the above-described embodiments, but may be embodied as follows. (1) As an empty bobbin supplying device 21, as shown in FIG. 11, an empty bobbin supplying section 58 capable of accommodating only one empty bobbin E is provided below the shooter 38. Empty bobbin supply unit 5
8 is opened at the front side in the moving direction of the peg tray 2 moving below, and the open portion is covered by a regulation plate 59 which is urged to a closed position by a spring (not shown). A rotary solenoid 60 is fixed to the lower open side of the empty bobbin supplying section 58, and its drive shaft is moved to a restricting position where the peg tray 2 on the belt 17 can be engaged and a retracting position where it cannot be engaged. A restriction piece 61 that restricts the movement of the peg tray 2 is fitted and fixed. A sensor S3 for detecting the presence / absence of the peg tray 2 at a position corresponding to the empty bobbin supplying section 58 is arranged near the rotary solenoid 60. Then, the sensor S3 detects the peg tray 2, the drum 41 is rotated with both the detection sensors S1 and S2 off, and one empty bobbin E is supplied from the empty bobbin storage box 37. When the empty bobbin E is mounted on the peg 2b, the restricting piece 61 is arranged at the retracted position, the peg tray 2 starts to move together with the belt 17, and the empty bobbin E resists the biasing force of the spring to restrict the restricting plate 59. Move away by pushing. In this case, a normal peg tray having a conical tip of the peg 2b may be used as the peg tray 2 without any problem.

(2) In the first embodiment, the front and rear walls of the empty bobbin supplying section 58 in the moving direction of the peg tray 2 are moved to the side that allows the empty bobbin E in which the peg tray 2 is inserted to pass. It can be opened. The inclination of the peg tray 2 at the position where the guide member 18 of the bobbin transfer device 14 corresponds to the belt conveyor 20 is
Only the full bobbin F that is inserted into the empty bobbin F is engageable with the belt 30 and the empty bobbin E is disengaged, and the pressing plate 34 is omitted. A position where the pressing plate 34 is arranged at a position where the distance between the pressing plate 34 and the belt 30 is larger than the outer diameter of the empty bobbin E without omitting the pressing plate 34, and the empty bobbin E inserted in the peg tray 2 is allowed to pass. It may be placed at. In this configuration, the peg tray 2 having the empty bobbin E inserted therein does not pull out the empty bobbin E even when it passes through the position corresponding to the belt conveyor 20, and the empty bobbin E is inserted into the empty bobbin supplying section 58. pass. And full bobbin F
Only the belt conveyor 20 pulls out the pegs 2b from the pegs 2b and carries them into the bobbin storage container. Therefore, there is no need to transport an unnecessary empty bobbin to the next process. The number of empty bobbins E to be accommodated in the empty bobbin accommodating box 37 can be the same as the number of spindles of the spinning machine stand.

(3) In the second embodiment, not only the empty bobbin E but also the tubular thread wound on only a part of the bobbin is selected together with the empty bobbin E to obtain the full bobbin F and the full bobbin F. It is also possible to adopt a configuration in which a similar yarn is stored in the bobbin storage container 50. For example, the second sensor SS2 is installed at a position where only the portion corresponding to the outer portion of the wound yarn can be detected, and while the ON signal is continuously output from the first sensor SS1, the The bobbin is discharged from the opening except when an ON signal is output from the second sensor SS2. In this case, the full bobbin F and the full bobbin F in the next process.
As a result, the number of times the yarn is spliced in the winder is reduced.

(4) In the first embodiment, the extracting member may be provided without providing the pressing plate 34, and in the second embodiment, the extracting plate 52 may be provided without providing the extracting member 52.

(5) As shown in FIG. 12, the belt 30 of the belt conveyor 20 is configured to run horizontally on the upper side, and an opening 53 is provided at a location corresponding to the horizontally running portion. In this case, the position at which the tubular yarn such as the full bobbin F is carried out from the belt conveyor 20 is lowered, and the yarn is less likely to be damaged by the impact when dropped into the bobbin accommodating container 50. or,
When the empty bobbin E is discharged from the opening portion 53, the empty bobbin E slips and descends, so that there is no possibility of failure in discharging.

(6) A reflection type sensor may be used as the bobbin identifying means, or a contact type sensor may be used instead of the non-contact type sensor. Further, a line sensor is provided as the bobbin identifying means, and the empty bobbin E, the full bobbin F, or the bobbin in which only a part of the bobbin is wound can be identified from the state of the output signal while the bobbin passes through the position corresponding to the line sensor. You may.

(7) Instead of the air nozzle 54 as the discharging means, a structure may be adopted in which the pressing member is reciprocated by a cylinder or the like so as to traverse the belt 30. (8) The pressing plate 34 itself may be composed of a leaf spring.

(9) The belt 17 is not limited to a flat belt having a three-layer structure, and a flat belt having a single-layer structure, a V belt, or a round belt may be used. Further, the guide piece 24 and the leaf spring 25 may be omitted.

(10) Instead of disposing the empty bobbin supplying device 21 on the extension line of the first conveying device T1, the belt 17 is provided.
May be disposed at a position corresponding to a portion traveling in a direction orthogonal to both the transport devices T1 and T2.

(11) The connecting rail 8 may be formed in an arc shape so that the peg tray 2 is transferred at the connecting portion by the carrying operation of the peg tray 2 by the first carrying device T1.

(12) A belt conveyor may be provided as a connecting portion to transfer the peg tray 2 from the first transfer device T1 to the second transfer device T2. In this configuration, the peg trays 2 do not necessarily have to be arranged on the connection portion so that they are always in contact with each other, and, finally, the two transport devices T are not required.
It suffices to dispose them on the T1 and T2 in a contact state. For example, a sensor for detecting the peg tray 2 on which the bobbin is mounted is provided at the first end and the second end of the connecting portion, and the first transport device T1 is provided.
Count the number of peg trays 2 sent to the connection part from. Then, after reaching the predetermined number, the first transfer device T
The operation of No. 1 is stopped, and thereafter, only the second transfer device T2 is operated to arrange the peg tray 2 at a predetermined position. In this case, the number of peg trays 2 can be reduced.

(13) Instead of a device that uses a transfer rail 3 that carries the peg trays 2 in a single row and reciprocates as both transfer devices T1 and T2, see Japanese Patent Laid-Open No. 60-139836.
A device having a structure in which a peg tray is placed on a guide rail and a rod provided with a locking claw is reciprocally moved by an air cylinder like the device disclosed in Japanese Patent Laid-Open Publication No. 2005-242242 may be adopted.

(14) Since it is extremely rare for all the machine stands to perform the pipe replacement work at the same time, the belt conveyor 20 is not provided for each spinning machine stand 1 and a movable type is adopted to provide a plurality of machines. The spinning machine base 1 may be shared. In this case, the cost is low.

(15) Instead of the operator moving the carrier truck 51 for transporting the bobbin accommodating container 50, the carrier carriage 51 may be automatically moved on the rail laid between the next step and the next step. In this case, transportation to the next process becomes easy.

(16) The bobbin transfer device 14 may be provided on the gear end side instead of the out-end side of the spinning machine base 1, or may be applied to a ring twisting machine other than the ring spinning machine.

Inventions other than those described in the claims that can be understood from the above-described embodiment and modifications will be described below along with their effects. (1) In the invention according to any one of claims 1 to 5, a pressing member that engages with a bobbin inserted in the peg tray above the lower end of the belt conveyor to press the bobbin toward the belt conveyor, The belt is urged toward the belt conveyor and is arranged so as to be movable from a state where the minimum distance from the belt of the belt conveyor is smaller than the outer diameter of the empty bobbin to a state where the bobbin is allowed to pass. In this case, the empty bobbin and the full bobbin are reliably pulled out from the peg while the peg tray passes through the position corresponding to the belt conveyor.

(2) In the invention described in claim 4, the bobbin discharging means includes an air nozzle for injecting compressed air so as to discharge the empty bobbin to the side of the belt conveyor. In this case, the structure is simpler than that of a mechanism that comes into contact with an empty bobbin and discharges it from the belt conveyor, and there is no risk of interfering with the succeeding bobbin even if the distance from the succeeding bobbin is short.

[0074]

As described above in detail, according to the invention described in claim 1, the operation timings of the conveying devices arranged on both sides of the spinning machine stand are such that the bobbin attached to the peg tray is removed and the bobbin is attached. The structure is simple and the control is easy without being affected by the supply timing of the empty bobbin to the peg tray that has been removed.

In addition to the above effects, the empty bobbin is automatically mounted on the peg when the peg tray passes below the empty bobbin supply section. According to the third aspect of the present invention, even if the frictional force between the belt and the peg tray is small, the peg tray reliably engages the empty bobbin and passes the empty bobbin.

In addition to the above effects, the inventions according to claims 4 and 5 can avoid mixing empty bobbins into the container in which the full bobbin (tubular yarn) is accommodated. Further, in the invention according to the fifth aspect, it is possible to easily distinguish the empty bobbin and the full bobbin with the two sensors.
