As shown in FIG. 1, the peg trays 2 are placed on the guide passages 17 of the second connection portion 4 in a state in which the peg trays 2 are in contact with each other upstream of a position corresponding to the turntable 39. The gap corresponding to two peg trays 2 is vacant at the position corresponding to, and the peg trays 2 are placed in contact with each other on the downstream side in the moving direction of the peg trays 2. An empty bobbin E is mounted on the peg tray 2 downstream of the bobbin shooter 32, and no bobbin is mounted on the peg tray 2 upstream of the bobbin shooter 32.

In this state, the air cylinders 11 and 12 of the two transfer devices T1 and T2 are simultaneously operated based on a command from the control device C.
It is moved forward with a stroke slightly larger than double. The peg tray 2 is reliably transported by the forward movement of the transfer rail 5 at the time of forward movement of the transfer rail 5 by the action of the locking projections 5 a protruding from the upper surface of the transfer rail 5. With the forward movement of the transfer rail 5 of the second transfer device T2, the entrance T2a of the second transfer device T2
A space is formed in which two peg trays 2 can be arranged. Since the transfer rail 5 of the first transfer device T1 also moves forward at the same time, the two peg trays 2 are pushed into the first connection portion 3 with the forward movement and the second tray 2 of the first connection portion is moved. The two tag trays 2 placed on the end side are sequentially fed into the space, that is, the support.

The transfer rail 5 of the second transfer device T2
With the forward movement, the two peg trays 2 placed at the outlet portion T2b of the second transfer device T2 are sent out to the second connection portion 4. Then, the peg tray 2 disposed upstream of the turntable 39 in the guide passage 17
When it is moved on the turntable 39 by the number of pieces, it is positively moved by the turntable 39. Therefore, when the movement (forward movement) of both transfer rails 5 in the feed direction is completed, a space where two peg trays 2 can be arranged is formed at a position corresponding to the turntable 39.

When the movement of the transfer rail 5 is completed, the locking projection 7a of the positioning member 7 enters the locking recess 2a of the peg tray 2, and a gap is formed between the locking recess 2a and the locking projection 7a. It is arranged in the state. When the transfer rail 5 is moved backward, the locking projections 7a that have entered the locking recesses 2a engage with the locking recesses 2a to prevent the peg tray 2 from retreating. It is arranged at a predetermined pipe replacement position corresponding to 8. When the transfer rail 5 is moved backward, the locking projection 5a pushes up the tag tray 2 whose movement is restricted by the action of the locking projection 7a, and passes below it. Also, the second transfer device T2
When the transfer rail 5 moves backward, a force is applied to the tag tray 2 supported by the support portion toward the first connection portion 3 via the locking projection 5a.
Is in contact with the tag tray 2 in the connecting portion 3 of the connecting portion 3, the movement thereof is restricted and is held on the supporting portion.

The peg tray 2 sent from the second transfer device T2 to the second connection portion 4 is
When passing through the position corresponding to the above, the bottom of the full bobbin F or the empty bobbin E mounted on the peg 2b is brought into a state of engaging with both the extracting members 28a and 28b. The bobbin B is withdrawn from the peg 2b by the action of the two withdrawing members 28a and 28b with the movement of the peg tray 2, and at the same time falls down to the belt conveyor 20 side and is discharged onto the belt conveyor 20. The full bobbin F and the empty bobbin E are conveyed upward with the movement of the belt 24 and discharged into the storage container 51 in a state where the downward movement is restricted by the restriction pieces 27 protruding from the belt 24. Is done.

The peg tray 2 from which the full bobbin F or the empty bobbin E has been removed will eventually move to a position corresponding to the front end of the bobbin shooter 32. In the state where the air cylinder 12 is located at the original position, as shown in FIG. 10, the locking portion 2f of one peg tray 2 enters the notch portion 32b of the bobbin shooter 32, and the foremost empty bobbin E And are not engaged. When the air cylinder 12 is operated from this state and the peg tray 2 is moved by a predetermined amount, the locking portion 2f engages with the empty bobbin E during the movement,
The empty bobbin E is moved to the front side against the urging force of the ball 37 and the regulating member 38. As a result, the empty bobbin E is disengaged from the ball 37 and the regulating member 38, and the peg 2b
Attached to. Then, the peg tray 2 on which the empty bobbin E is mounted is moved to a position corresponding to the turntable 39. The peg tray 2 engaged with the turntable 39 is positively transferred by the rotation of the turntable 39, and is moved to a position where it comes into contact with the peg tray 2 transferred earlier. Also, on the upstream side of the guide passage 17, the peg tray 2 that was in contact with the peg tray 2 that was in a state corresponding to the foremost empty bobbin E also moved after the empty bobbin E was mounted on the peg 2 b during the movement. It is moved to a downstream side from the shooter 32.

When the empty bobbin E is unloaded from the bobbin shooter 32 and the two bobbin detecting sensors S1 and S2 are not detecting the bobbin, the drum 34 is rotated by a predetermined amount and the single bobbin E is removed. The empty bobbin E is supplied to the bobbin shooter 32 after being sent out from the empty bobbin storage box 30.

The empty bobbin E is the peg 2b of the peg tray 2.
It is important that it is arranged at a predetermined position corresponding to the spindle 8 in a state where the spindle 8 is mounted straight. And FIG.
As shown in (2), if the empty bobbin E is inserted while the trailing yarn residue Y or fly cotton is attached to the peg 2b, the empty bobbin E may not be mounted straight. However, in this embodiment, while the peg tray 2 is stopped near the notch 32b of the bobbin shooter 32 and upstream in the moving direction of the peg tray 2, exhaust air during the operation of the air cylinders 11, 12 in the feed direction is reduced. Each peg 2b is sprayed. Therefore, even if fly waste or tail yarn residue is attached to the peg 2b, it is blown off. Therefore, when the empty bobbin E is supplied, the fly waste or tail yarn residue is not attached to the peg 2b, and the empty bobbin is not attached. E is mounted straight on the peg 2b.

Exhaust gas when the air cylinders 11 and 12 are operated in the return direction is blown toward the balls 37 of the bobbin shooter 32 by the pipe lines 49 and 50. Therefore, it is possible to prevent fly waste and the like from being bitten by the ball 37 when the ball 37 moves in and out of the movement path of the empty bobbin E, and to prevent malfunction due to biting of the fly waste and the like.

Hereinafter, similarly, the control device C controls each sensor S
The detection signals from 1a, S2a, S1b, and S2b are input, and the immersion and protruding state of both piston rods 11a, 12a are confirmed, and both air cylinders 11, 12 simultaneously move forward and backward the transfer rail 5 respectively. So that the air cylinder 11,
Activate 12. Therefore, two peg trays 2 on the transfer rail 5 of the second transfer device T2 are unloaded onto the second connecting portion 4 at a time. In addition, two peg trays 2 are sequentially supplied from the second connecting portion 4 onto the transfer rail 5 of the first transfer device T1, and the peg tray 2 on which the full bobbin F or the empty bobbin E is mounted is moved to the first peg tray 2. The two pieces are sequentially transferred from the first transfer device T1 to the second transfer device T2 via the connection part 3. Then, when a predetermined number of the peg trays 2 with the empty bobbins E mounted thereon are arranged on both the transfer devices T1 and T2, the unloading of the full bobbins F and the loading of the empty bobbins E are completed.

Then, the storage container 51 is transported to the next step by the transport trolley 52 by the operator. The peg tray 2 fed from the second transfer device T2 is not limited to the one equipped with the full bobbin F, but may be the one equipped with the empty bobbin E.
In this apparatus, the empty bobbin E is housed in the housing container 51 together with the full bobbin F and sent to, for example, a winder process. However, there is no problem because the winder has a device for selecting the empty bobbin E and the full bobbin F.

The empty bobbin E is supplied to the empty bobbin storage box 30 of the empty bobbin supply device 29 by the worker.
When the container 51 is transported from the next step in Step 2, the empty bobbin E is stored in the container 51 and transported.
This is done by moving from within 1.

Therefore, in this embodiment, the following effects can be obtained. (1) Pipe line 4 for guiding exhaust of air cylinders 11 and 12
The outlets 47a and 48a of the pegs 7 and 48 are disposed at positions facing the pegs 2b of the peg tray 2 when the bobbin B is not mounted. Therefore, the empty bobbin E is inserted into the peg 2b in a state where the tail yarn residue and fly cotton are not attached to the peg 2b of the peg tray 2, and the empty bobbin E is mounted on the peg tray 2 at a predetermined position. Can be placed.

(2) No extra energy is used for cleaning because the exhaust air of the air cylinders 11 and 12 is used. (3) The air cylinders 11 and 12 are
The exhaust when the transfer rail 5 is moved to the return side is guided, and the exhaust is blown to the peg 2b of the peg tray 2 in the stopped state. Therefore, the cleaning effect of the pegs 2b is higher than in the case of blowing the exhaust gas when moving the transfer rail 5 to the feed side.

(4) Outlets 47a, 4 of pipes 47, 48
Since 8a is arranged near the notch 32b of the bobbin shooter 32, the empty bobbin E is supplied immediately after the peg 2b is cleaned by the exhaust gas. Therefore, after cleaning, there is almost no risk that fly waste or trailing thread remains on the peg 2b before the empty bobbin E is supplied.

(5) When the peg tray 2 passes below the empty bobbin supply device 29, the empty bobbin E is automatically supplied to the peg 2b with the movement of the peg 2b. The configuration is simplified as compared with a supply mechanism configured to supply the empty bobbin E by dropping toward the peg 2b in a stopped state.

(6) One stroke of the transfer rail 5 for intermittently moving the page tray 2 at a predetermined pitch is set to twice or more the spindle pitch, and the page tray 2 is moved twice the spindle pitch. Therefore, the number of actuations of the air cylinders 11 and 12 for reciprocating the transfer rail 5 until the unloading of the full bobbin F and the supply of the empty bobbin E are completed is half that of the apparatus for moving the peg tray 2 by the spindle pitch. The transport time per peg tray 2 is greatly reduced.

(7) Two stopped peg trays 2
In addition, when the air cylinders 11 and 12 move the transfer rail 5 to the return side of the peg tray 2, exhaust air is supplied to the pipelines 47 and 4.
8 from the outlets 47a and 48a.
Therefore, the cleaning effect is improved as compared with the case where the exhaust gas of one air cylinder is blown in two parts.

(8) Exhaust when the air cylinders 11 and 12 move the transfer rail 5 to the feed side of the peg tray 2 is discharged through pipe lines 49 and 50 to a predetermined location where the accumulation of fly waste in the bobbin changing device is not preferable. In the embodiment, it is sprayed on the ball 37 of the bobbin shooter 32. Therefore, fly cotton or the like is prevented from being caught between the surface of the ball 37 and the support portion of the ball 37, and the empty bobbin E is smoothly supplied to the peg 2b in a predetermined posture.

(9) Guide passage 17 of second connecting portion 4
A turntable 39 is provided in the middle of the guide path 17, and a gap of approximately two peg trays 2 is positively formed in the guide passage 17 by the rotation of the turntable 39. Therefore, when the transfer rail 5 of the second transfer device T2 moves forward, the two peg trays 2 on the transfer rail 5 are smoothly fed into the second connection portion 4.

(10) Guide passage 1 of second connecting portion 4
A gap having a size corresponding to approximately two peg trays 2 formed at 7 is formed near the downstream side of the bobbin shooter 32. Therefore, when the peg tray 2 is moved in a state of being engaged with the empty bobbin E in the bobbin shooter 32 during forward movement of the transfer rail 5 of the second transfer device T2, the resistance is reduced, and the peg tray 2 moves smoothly. Then, the supply of the empty bobbin E is smoothly performed.

(11) The outlets 47a of the pipes 47 and 48,
Since the outlets 48a are arranged in a state of extending horizontally, the outlets 47a, 48a are mounted so as to point to the predetermined positions of the pegs 2b, compared with the case where the outlets 47a, 48a are mounted with the outlets 47a, 48a inclined upward or downward. And easier.

The embodiment is not limited to the above, and may be embodied as follows, for example. ○ As a configuration in which the exhaust air when the air cylinders 11 and 12 are operated to the return side is blown to the two peg trays 2,
Instead of guiding the exhaust air of both air cylinders 11 and 12, respectively, as shown in FIG.
Is disposed at a position facing the peg 2b. In this case, the pipe 47 is unnecessary for cleaning the peg 2b, and the piping work is simplified.

As shown in FIG. 11, a pipe 47 not used for cleaning the peg 2b is disposed so that its outlet 47a is directed to a position corresponding to the turntable 39, for example. The outlet 47a is provided below the cover plate 18a. In this case, since the portion corresponding to the turntable 39, which is one of the portions that dislikes the accumulation of fly waste, is cleaned, the peg tray 2 moves smoothly.

Instead of using the conduits 49 and 50 for guiding the exhaust gas used for cleaning the bobbin shooter 32 for cleaning the ball 37, the distal end side of one conduit 49 is forked and used for cleaning the ball 37. The other pipe 50 may be used for cleaning the inside of the bobbin shooter 32. In this case, fly waste and the like hardly accumulate in the bobbin shooter 32,
The empty bobbins E are sequentially and smoothly supplied to the peg tray 2 while being aligned in a predetermined posture.

The bobbin shooter 32 may be arranged such that the outlet of the conduit for guiding the exhaust of the air cylinders 11 and 12 faces the peg 2b of the peg tray 2 when the bobbin B is not mounted. The position may be any position after the bobbin B is extracted by the full bobbin extracting section 19 and before the empty bobbin E is supplied.

The exhaust used for cleaning the peg 2b is:
Not only the exhaust air at the time of operation of the air cylinders 11 and 12 to the return side, but also the exhaust air at the time of operation to the feed side may be used. However, since the peg tray 2 moves during the operation to the feed side, it is preferable to use the exhaust gas during the operation to the return side for cleaning the peg 2b.

○ As shown in FIG.
The configuration is such that the supply of compressed air to 1 and 12 is controlled by a solenoid valve 53 composed of a common 5-port 3-position switching directional control valve. The air cylinder 11 is connected to a port A5 via a pipe 54 at a piston end, and is connected to a port A6 via a pipe 55 at a piston rod end.
It is connected to the. The pipe 54 is branched and connected to the piston rod end of the air cylinder 12. Pipe line 5
5 is branched and connected to the piston-side end of the air cylinder 12. Supply port P3 of solenoid valve 53
Is connected via a supply line 56 to a source of compressed air (not shown). The solenoid valve 53 is an air cylinder 1
When driving the feed trays 1 and 12 to the peg tray feed side, the supply port A5 communicates with the port P3 and the port A6.
The spool is disposed at a position where the spool communicates with the exhaust port E5. When driving the air cylinders 11 and 12 to the return side, the spool is disposed at a position c where the supply port A6 communicates with the port P3 and the port A5 communicates with the exhaust port E6. Then, the distal end side of the conduit 57 that guides the exhaust gas at the time of the operation to the return side is made bifurcated and used for cleaning the peg 2b. Exhaust gas during operation to the feed side is guided to a conduit 58 and used for cleaning a desired portion. In this case, the supply of compressed air to both air cylinders 11 and 12 can be controlled by one solenoid valve 53, and the manufacturing cost of the device is reduced by the solenoid valves 41 and 4 for each air cylinder 11 and 12.
It becomes cheaper than the case of providing 2. Also, piping work is simplified.

Outlets 47 of conduits 47 to 50 for guiding exhaust
a to 50a may be tapered to increase the pressure of the exhaust gas to be injected. Further, the outlets 47a and 48a are not limited to being horizontal, and may be provided in a state of being inclined upward or downward.

The strokes of the air cylinders 11 and 12 may be set to a value slightly larger than three times the spindle pitch, or a value slightly larger than an integral multiple of four or more. However, when it is larger than four times, the space for securing the stroke of the transfer rail 5 becomes large, which is not preferable.

The strokes of the air cylinders 11 and 12 may be set to a value slightly larger than the spindle pitch, and the peg trays 2 may be fed one by one to the second connecting portion 4. In the case where the number of weights of the machine base 1 is not very large, with this configuration, the discharge of the full bobbin F and the supply of the empty bobbin E are completed by the next doffing.

In a configuration in which the strokes of the air cylinders 11 and 12 are set to values slightly larger than the spindle pitch, the empty bobbin supply device 29 is provided below the shooter 31 and can hold only one empty bobbin E. A supply unit may be provided to supply the empty bobbin E to the peg 2b in a state where the peg tray 2 is stopped below the empty bobbin supply unit. In this case, peg 2b is used as peg tray 2.
There is no problem using a regular peg tray with a conical tip.

A belt conveyor may be provided as the first connection part 3 so that the peg tray 2 is transferred from the first transfer device T1 to the second transfer device T2 by a belt conveyor. In this configuration, the peg trays 2 do not always need to be arranged on the first connection portion 3 in a state of being in contact with each other, and the number of peg trays 2 can be reduced.

Instead of operating both transfer devices T1 and T2 simultaneously, the transfer rail 5 of the second transfer device T2 is reciprocated, and then the transfer rail 5 of the first transfer device T2 is reciprocated. It may be configured. In this case, the transfer rail 5 of the first transfer device T1 is reciprocated in a state where a space for mounting two tag trays 2 is secured at the inlet portion T2a of the second transfer device T2. There is no need to provide a bearing at T2a.

The locking projections 5 a are not necessarily required for each peg tray 2, but may be provided for each of the plurality of peg trays 2. In place of the apparatus using the transfer rails 5 that reciprocate by mounting the peg trays 2 in a single row as the transfer devices T1 and T2, the peg tray 2 is replaced by a device as disclosed in JP-A-57-161133. A device that is placed on a guide rail and reciprocates a rod provided with a locking claw with an air cylinder may be employed. In this case, the guide rail constitutes the tag tray passage, and the rod provided with the locking claw and the air cylinder constitute the transfer member.

Instead of supporting the transfer rail 5 with the bracket 10 having the guide groove 10a, a method disclosed in
Similarly to the apparatus disclosed in Japanese Patent No. 4839, the transfer rail 5 may be supported via a ball bearing.

The empty bobbin supply device 29 may be provided on an extension of the first transfer device T1. As the second connecting portion, an endless belt wound around a driving pulley and a plurality of guide pulleys and a peg tray along the belt as in the device disclosed in JP-A-8-188340. A transport device having a linear guide member that is arranged to sandwich the peg and elastically presses the peg tray together with the belt may be used.

The first connection part 3 may be provided on the out-end OE side, and the second connection part 4 may be provided on the gear end GE side. ○ The present invention is not limited to the ring spinning machine, but may be applied to a ring twisting machine.
