2. Description of the Related Art Generally, yarn produced by a spinning machine, particularly a ring spinning machine, is rewound by a winder into a package of a size and shape suitable for subsequent processing. In order to save labor and improve productivity, the spinning machine and the winder are directly connected through a bobbin conveyance path, and the full bobbin (tube yarn) from the spinning machine is sent to the winder, and the empty bobbin after being used in the winder is transferred to the spinning machine. A variety of spinning winders have been proposed for conveying and supplying to the respective spinning machines. This type of spinning winder uses a peg tray with pegs protruding from the upper surface to transport full bobbins and empty bobbins, as disclosed in Japanese Utility Model Application Publication No. 60-50665 and Japanese Patent Application Publication No. 60-52475. Publication, JP-A-62-1
This is disclosed in JP-A No. 80881 and the like. Furthermore, a device has been proposed in which the spinning frame frame is equipped with a transport device using a peg tray, and the bobbin is removed from the peg tray when transporting a full bobbin to the winding process or transporting an empty bobbin from the winding process. (For example, Japanese Patent Application Laid-open No. 58-7

[Problems to be Solved by the Invention] By the way, when heat-setting the yarn, it is necessary to heat-set the yarn before winding it back in the winder, and it is not possible to directly connect the spinning machine and the winder. Furthermore, since older models of winders do not use peg trays, it is inconvenient to transport a full bobbin to the winding process with it inserted into the peg tray. Under these circumstances, currently only a few percent of spinning machines have spinning winders that directly connect spinning machines and winders. but,
Since it is convenient to transport bobbins using a peg tray, full bobbins doffed onto the peg tray at the spinning machine stand are stored in a bobbin storage container for transport to the next process, and empty bobbins are supplied to the peg tray. A device is required to do this. The method of picking up a full bobbin from a peg tray and storing it in a bobbin storage container is to use a picker that engages the bottom of the bobbin with the peg in between and pushes up the bobbin, or a picker that works to push up the bobbin by grasping the top of the full bobbin. There is a method of storing a full bobbin in a full bobbin storage container using a device (Japanese Patent Application Laid-open No. 161133/1983). However, with this method, a full bobbin extraction device is required for each spinning machine.
An empty bobbin supply device is required, and equipment costs are high. In addition, a full bobbin storage container is required for each spinning machine, and it takes time and effort to transport the storage container from each spinning machine end to the collection location of the storage containers.

A rotary solenoid 23 is fixed on the guide rail 8 of the full bobbin conveyance path 5a on the upstream side of the notch 22, and the rotary solenoid 23 has a drive shaft that rotates in a plane intersecting the moving direction of the belt 7. A regulating member 24 is fitted and fixed, and is moved between a regulating position where it can engage with the outer circumferential surface of the peg tray 3 and a standby position where it cannot engage with it to regulate the movement of the peg tray 3.

As shown in FIGS. 1 and 4, the empty bobbin supply device 10 includes an empty bobbin storage box 25, an empty bobbin payout drum 26 disposed near the front of the bottom of the storage box 25, and an empty bobbin storage box 25. a hopper 27 that receives the empty bobbins E dropped one by one from the outlet 25a of the hopper 27 and changes the attitude of the empty bobbin E so that the bottom of the empty bobbin E is on the lower side;
It consists of a chute 28 disposed below the hopper 27 and bobbin detection sensors S1 and S2 disposed at positions corresponding to the chute 28. The chute 28 is open on the side in the movement direction of the peg tray 3 moving below, and the open portion is covered by a regulating plate 29 biased to a closed position by a spring (not shown).

As shown in FIGS. 1 and 4, a rotary solenoid 30 is fixed to the lower opening side of the shooter 28.
A regulating piece 31 is fitted and fixed on the drive shaft to restrict the movement of the peg tray 3 by being moved to a regulating position where it can engage with the peg tray 3 on the belt 12 and a retracted position where it cannot engage. Further, a peg tray detection sensor 32 is disposed near the rotary solenoid 30 to detect the presence or absence of the peg tray 3 disposed at a position corresponding to the shooter 28.

Next, the operation of the apparatus constructed as described above will be explained. After completion of the tube change operation in which the empty bobbin E on the peg tray 3 and the full bobbin F on the spindle, which are prepared on the transfer devices 2a and 2b of the spinning frame frame 1, are exchanged by a tube change device (not shown), the transfer is carried out. The devices 2a, 2b and the bobbin transfer device 9 are operated, and the conveyor 5
is driven, and the peg tray 3 in which the full bobbin F doffed on the spinning frame frame 1 is inserted is transferred onto the full bobbin transport path 5a of the transport conveyor 5.

The peg tray 3 with full bobbins transferred onto the full bobbin transport path 5a is moved to the transport conveyor 5 where the bobbin storage container is disposed at the location S by the drive of the transport conveyor 5.
conveyed to the end of the Then, with the bobbin storage container 13 placed on the transport cart 33 placed below the bobbin storage container placement location S, the bobbin transport device 11 and the empty bobbin supply device 10 are driven. After the bobbin transport device 11 is driven, the rotary solenoid 23 disposed in the peg tray discharge section 17 of the full bobbin transport path 5a is activated, and the regulating member 24 engages with the peg tray 3 on the full bobbin transport path 5a. placed in an impossible evacuation position. As a result, the peg tray 3 in which the full bobbins F on the full bobbin transport path 5a are inserted is guided by the guide member 19 and sequentially transferred onto the belt 12 of the bobbin transport device 11 via the notch 22. The peg tray 3 transferred onto the belt 12 is the guide member 1
9, the attitude of the full bobbin F is changed from a vertical state to an almost horizontal state, and it moves in that state to a position near the bobbin storage container arrangement location S.
At the position corresponding to , the full bobbin F changes its attitude and moves so that it is directed downward from the horizontal. Then, the peg tray 3 into which the full bobbin F is inserted is transferred to the full bobbin storage container 1.
3, the full bobbin F inserted into the peg tray 3 is detached from the peg 3a and moved into the bobbin storage container 1.
3 and is contained inside.

Peg tray 3 after full bobbin F is removed
Due to the action of the guide member 19, the attitude of the peg 3a is changed again to the vertical state, and the empty bobbin supply device 1
It moves to a position corresponding to the lower end of the shooter 28 of No. 1, is engaged with the regulating piece 31, and waits at that position. When the peg tray 3 reaches the relevant position, the peg tray detection sensor 32
detects it. When the peg tray detection sensor 32 detects the peg tray 3 and the two bobbin detection sensors S1 and S2 of the empty bobbin supply device 11 do not detect the bobbin, the empty bobbin payout drum 26 is intermittently rotated. An empty bobbin E of books is sent out from the empty bobbin storage box 25, and as shown in FIG. It is inserted into the peg 3a of the peg tray 3 waiting below. When the bobbin detection sensor S1 provided in the hopper 27 detects an empty bobbin E, the rotation of the empty bobbin payout drum 26 is stopped. When the bobbin detection sensor S2 disposed at the bottom of the chute 28 detects an empty bobbin E, the rotary solenoid 30 is driven, the regulation piece 31 is rotated to the retracted position, and the peg tray 3 starts moving together with the belt 12. The empty bobbin E pushes away the regulation plate 29 of the chute 28 against the biasing force of the spring and moves while being inserted into the peg tray 3. and,
After the attitude of the empty bobbin E is changed to almost horizontal by the action of the guide member 19 and moved to the vicinity of the peg tray introduction part 18 of the empty bobbin transport path 5b, the attitude of the empty bobbin E is changed again to the vertical state and the empty bobbin is transported. Transferred onto Road 5b,
As the belt 7 moves on the empty bobbin transport path 5b, the empty bobbin is transported to the spinning frame frame 1 side. In addition, when the peg tray 3 moves from the position corresponding to the shooter 28, the regulating piece 31 is arranged at the regulating position again.

As described above, the full bobbin F can be reliably removed from the peg tray 3 by simply changing the attitude of the full bobbin F, and moreover, the full bobbin F can be removed while the peg tray 3 is moving on one belt 12. Since the discharge of the empty bobbin E and the supply of the empty bobbin E are completed, the processing capacity is improved. Thereafter, the peg trays 3 with full bobbins F inserted therein are sequentially transferred from the full bobbin transport path 5a to the bobbin transport device 11, and the full bobbins F are transferred to the bobbin storage container 13 at the bobbin storage container arrangement location S.
After the empty bobbin E is inserted into the peg 3a at a position corresponding to the empty bobbin supply device 10, it is discharged onto the empty bobbin transport path 5b. Shortly before the bobbin storage container 13 mounted on the transport trolley 33 becomes full, the regulating member 24 provided on the full bobbin transport path 5a is placed at the regulating position to prevent the flow from the full bobbin transport path 5a to the bobbin transport device 11. Transfer of the peg tray 3 is stopped. As a result, the peg tray 3 with full bobbins transported on the full bobbin transport path 5a waits on the upstream side of the regulating material 24. Then, the bobbin storage container 13 filled with full bobbins F is transported to the next process by the transport truck 33 by the operator. Note that the empty bobbin storage box 25 of the empty bobbin supply device 10 is replenished with empty bobbins E by storing the empty bobbins E into the bobbin storage container 13 when the operator transports the bobbin storage container 13 from the next process using the transportation cart 33. This is done by transporting the bobbin and transferring it from inside the bobbin storage container 13.

(Embodiment 2) Next, a second embodiment will be described with reference to FIG. In this embodiment, when the full bobbin F inserted in the peg tray 3 moves above the bobbin storage container arrangement location S, the full bobbin F can be discharged while its posture is maintained in a horizontal state. This embodiment is different from the previous embodiment, and the other configurations are the same. At a location where the belt 12 runs horizontally near the upper end of the bobbin container 13 disposed at the bobbin container arrangement location S, a guide member 19 holds the full bobbin F inserted in the peg tray 3 so that its posture is horizontal. It is arranged to move while being held. A scraper 34 that can engage with the bottom of the full bobbin F inserted into the peg tray 3 is disposed at the same location. scraper 34
has an engaging surface 34a whose distance from the belt 12 gradually increases in the direction of movement of the peg tray 3, and is arranged so that the peg tray 3 passes below the scraper 34.

When the full bobbin F inserted into the peg tray 3 moves above the bobbin storage container arrangement location S, the bottom of the full bobbin F engages with the scraper 34, and the peg tray 3
As the bobbin F moves, the full bobbin F gradually slips out of the peg 3a and falls into the bobbin storage container 13, as shown by the chain line in FIG. Therefore, it is not necessary to change the arrangement state of the guide member 19 so that the attitude of the full bobbin F is directed downward from the horizontal at a position corresponding to the bobbin storage container 13 arranged at the bobbin storage container placement location S. The scraper 34 is configured to be rotatable and is provided with a sensor that detects when the full bobbin F reaches the position where it engages with the scraper 34, and the scraper 34 moves the full bobbin F to the peg tray 3 based on a detection signal from the sensor. The peg 3a may be rotated in a direction in which it is removed from the peg 3a.
