Next, the transport control in the above configuration will be described. The bobbin transfer system is provided with a controller (not shown) for carrying out the bobbin transfer as shown in FIG. That is, the actual bobbins B ₁ that have been doffed and inserted into the transport bands 13a and 13b are continuously dispensed, and in parallel with the supply of the actual bobbins B ₁ according to the request of the winder 2. The reserve conveyor 3, which has previously stocked the empty bobbin-equipped tray T ₀ , receives the remaining real bobbins B ₁ and sequentially stocks them. Then, when the actual bobbin B ₁ has been dispensed, the reserve conveyor 3 has all the empty bobbin trays T _0
1 is replaced with the inserted tray T ₁ ,
In parallel with the subsequent return of the empty bobbin, the stocked actual bobbin B ₁ is sequentially supplied to the winder 2 and the discharged tray T ₀ with the empty bobbin is received.
Therefore, the required stock capacity RE of the reserve conveyor 3 is
It is expressed by the following equation.

RE = (empty bobbin return time / spinning time) × the number of spinning machine spindles × a ... Here, the spinning time is determined by conditions such as yarn count, tube yarn weight, etc., and empty bobbin return time Varies depending on the capacity of the spinning machine 1 and the number of spindles. In addition, a is a constant (for example, a = 1.1) in consideration of the margin time. In this way, by determining the capacity of the reserve conveyor 3 (the length and the number of the reserve lines 3a ... 3h), the reserve conveyor 3 can be reduced to the necessary minimum scale.

Next, the operation of this embodiment will be described.

First, a predetermined number of trays T ₀ with empty bobbins are stocked in each of the reserve lines 3 a ... 3 h,
An appropriate number of empty bobbin-equipped trays T ₀ are also provided on the empty bobbin direct feed path 8.
Is in a waiting state. Further, the winder 2 has finished winding the actual bobbin B ₁ and is on standby with knotting stopped. When the doffing of the spinning machine 1 is completed in this state, a doffing completion signal is issued and the winder 2 starts operation. At the same time, the real bobbins B ₁ are transferred to the winder 2 side by the transport bands 13a and 13b, and the tray T ₀ with an empty bobbin is cut out from the empty bobbin direct feed path 8 and communicated via the circulation path 9 and the intermediate conveyor 12. The position of the bobbin removing device 6 on the path 5 is reached. The bobbin removing device 6 extracts the empty bobbin B ₀ from the tray T and appropriately conveys it to the bobbin box 59 of each spinning machine by the bobbin conveyance guide 57. The empty tray T is connected to the actual bobbin insertion device 35 by the connecting path 5.
Is transferred to just below the chute 36. Then, under the condition that the actual bobbin B ₁ is near the upper opening of the chute 36 and the empty tray T is on standby, the transport bands 13a and 13b are driven by one pitch, and the actual bobbin B ₁ passes through the chute 36. It drops and is inserted into an empty tray T. This insertion is performed continuously. In this example,
First, one transport band 13a operates to dispense all the actual bobbins B _1, and then the other transport band 13b dispenses the actual bobbin B ₁ . In addition, both transport bands 13a, 13b
Alternatively, the actual bobbins B ₁ may be paid out alternately.
Tray T of real bobbin B ₁ with one side transport band
When the insertion into the tray is performed, the tray T is passed through on the opposite side. The tray T ₁ on which the actual bobbin B ₁ is inserted is the connecting path 5
Is caused to flow through the circulation path 9 via the intermediate conveyor 11,
When the actual bobbin direct feed path 7 is not full, it is fed into this direct feed path 7. On the other hand, when the actual bobbin direct feed path 7 is full, it is flowed to the reserve lines 3a ... 3h. Since the actual bobbin direct feed path 7 is empty at the initial stage, it is sent to this direct feed path 7.

In the meantime, on the winder 2 side, the actual bobbin B ₁ waiting in the winder 2 is rewound in each winding unit. Therefore, the tray T _{0 on} which the empty bobbin B ₀ (in some cases, with residual thread) is loaded is sequentially dispensed from each winding unit.
₀ is discharged to the empty bobbin direct feed passage 8 by the empty bobbin discharge passage 15. The discharge of the empty tray T ₀ is confirmed by the tray confirmation sensor 100 provided on the downstream side. When one empty tray T ₀ with an empty bobbin is discharged from the winder 2, one real bobbin B ₁ is discharged from the real bobbin direct feed path 7 and is directed to the real bobbin carry-in path 14 by the guide device 41 of the connection path 10. It is sent to the carry-in path 14. When there is no tray T ₁ (actual bobbin B ₁ ) in the actual bobbin direct feed path 7 (detected by the sensor 45 at the head of the actual bobbin direct feed path 7), the actual bobbin B ₁ is cut out from the reserve lines 3a ... 3h. Although so as to be, due to the presence of loaded trays T ₁ the reserve line 3a ... 3h empty bobbin with trays T ₀ on the actual bobbin direct path 7 until after interchanged in real trays T ₁ as described below, until it Is the actual bobbin direct feed path 7
The real bobbin B ₁ is paid out from. A sensor for confirming that the direct feed passage 8 is full is provided at the upstream end of the empty bobbin direct feed passage 8. When the sensor confirms that the empty feed passage 8 is full, the empty bobbin discharge passage 15 allows the tray with the empty bobbin. The discharge of T ₀ may be stopped.

The empty bobbin-equipped tray T ₀ that was on the empty bobbin direct feed path 8 is sent to the connecting path 5 and the actual bobbins B ₁ are inserted one after another by continuous actual bobbin payout. For this reason, the amount discharged from the winder 2 of the empty bobbin-equipped tray T ₀ exceeds the amount discharged from the empty bobbin direct feed path 8,
The tray T ₀ with empty bobbins is in a shortage state. When this state is detected by the tray sensor 45 provided on the way of the empty bobbin direct feed path 8, the reserve lines 3a ...
The tray T ₀ with the empty bobbin that has been stocked in the above is sequentially cut out from the A line 3a side and is sent to the empty bobbin direct feeding path 8 by the connecting path 9. On the other hand, in the actual bobbin direct feed path 7, the amount of the actual bobbin B ₁ required by the winder 2 is
Since the amount of the actual bobbin B ₁ continuously sent exceeds,
Eventually it will be full. When the tray sensor 45 at the upstream end detects this fullness, the guide device 41 is actuated, and the tray T ₀ with an empty bobbin is discharged to the empty A line 3a. After that, in the reserve conveyer 3, the tray T ₀ with an empty bobbin is cut out and the actual bobbin B _{1 is} cut out.
Are sequentially received from the A line 3a to the H line 3h (the tray T ₀ with an empty bobbin is sequentially provided from the A line 3a).
And the replacement with the actual tray T ₁ is completed). The empty bobbin B ₀ extracted by the bobbin extracting device 6 is sent to the spinning machine 1 side by the empty bobbin transport guide 57 and is temporarily stored in each bobbin box 59.

The reserve conveyor 3 eventually becomes the actual bobbin B ₁
Then, the full amount of the actual bobbin is dispensed. When the payout is completed, the empty bobbin B ₀ is returned. That is, the transport bands 13a and 13b that have been dispensed are driven in the direction M opposite to the dispensing direction L, and the empty bobbin insertion device 99 inserts the empty bobbin B ₀ into the empty peg P ₁ . First, the empty bobbin B ₀ is inserted into one of the transport bands 13a, and then the other bobbin B ₀ is inserted into the other transport port band 13b. The winder 2 continues to operate even during the time when the empty bobbin B ₀ is inserted. Therefore, the empty bobbin tray T ₀ is continuously discharged from the winder 2 and the actual bobbin B ₁ is continuously supplied to the winder 2. As a result, there is no real bobbin B ₁ on the real bobbin direct feed path 7. When the tray sensor 45 at the head detects that the actual bobbin B ₁ is gone, the actual bobbin B ₁ is cut out from the A line 3a side and sent to the actual bobbin carry-in passage 14. On the other hand, the tray T ₀ with an empty bobbin discharged from the winder 2 is connected to the empty bobbin direct feeding path 8
Then, the actual bobbin B ₁ is further cut out via the circulation path 9 and sequentially fed to the reserved lines 3a ... When the actual bobbins B ₁ are lost in the reserve lines 3a ... 3h, the operation of the winder 2 is temporarily stopped. At this time, the amount of empty bobbin B ₀ required for the doffing has already been transferred to the spinning machine 1 side, and when the empty bobbin B ₀ in the bobbin box 59 is completely inserted, the doffing can be performed, and Wait for the end of spinning 1.

As described above, the reserve conveyor 3 as a buffer is provided between the spinning machine 1 and the winder 2, and the spinning machine 1 out of the actual bobbins B ₁ delivered from the spinning machine 1 side.
The excess bobbin generated by the actual bobbin payout speed from the side and the processing speed of the winder 2 is stocked on the reserve conveyer 3, and the stocked bobbin B ₁ is completed and the transport band 13 of the empty bobbin B ₀ is completed.
Since the winders 2 are sequentially supplied during the insertion period to the a and 13b, the delivery of the actual bobbin B ₁ is performed early so that the transport bands 13a and 13b can be inserted to the empty bobbin B _0. The empty bobbin B ₀
And the operation of the winder 2 can be performed in parallel. That is, there is almost no time lag even if the processing capacity of the winder 2 and the production capacity of the spinning machine are approximately 1: 1 and there is no need to increase the number of winder spindles when automating the bobbin transfer. Further, it is not necessary to control the winder 2 and the spinning frame 1 in cooperation with each other, and even a line in which operation is controlled separately can be easily applied without significant change. That is, an extremely versatile bobbin transfer system is achieved.

Since the bobbin removing device 6 is provided in the connecting path 5 connecting the reserve conveyor 3 and the spinning frame 1, the bobbin transfer guide 57 can be made relatively short. When returning the empty bobbins B ₀ to the plurality of spinning machines 1, if the bobbin removing device 35 is installed on the winder 2 side, the transport path becomes radial and the mechanism becomes complicated. In the present invention, the hobbin transport guide 57 has a simple structure including a straight cross section and a small-sized branch portion 58. In addition, since the empty bobbin is transported in one direction, the operation of the conveyor 86 that constitutes the transport guide 57 can be simplified.

In this embodiment, the actual bobbin direct feed path 7 and the empty bobbin direct feed path 8 are connected to the reserve lines 3a ... 3h.
Since it is installed in the winder 2, it is possible to supply the real bobbin B ₁ to the winder 2 promptly after the start of dispensing, and it is possible to smoothly carry out the empty bobbin-equipped tray B ₀ and receive the real bobbin B ₁ .

Since the circulation path 9 is formed in a closed loop, the reserve line 3a can be formed by increasing the conveying speed.
It is possible to retry even if the tray T is not taken into 3h. That is, the trays T can be accurately stocked in the required reserve lines 3a ... 3h, and the transport speed can be increased. Further, during the empty bobbin return period, the empty bobbin-equipped tray B ₀ discharged from the winder 2 can be immediately carried into the reserve conveyor 3 without using the connecting path 5. Therefore, during this period, the drive of the communication path 5 and the intermediate conveyors 11 and 12 may be stopped.

Further, a cover 3 for covering the reserve conveyor 3
1 is provided, the passage between the winder 2 and the spinning machine 1 can be facilitated, and the cotton wool can be prevented from adhering to the actual bobbin B ₁ or the transport drive system.

In this embodiment, the reserve conveyor 3 is installed on the floor, but the reserve line 3a is used.
3h and the direct feed paths 7 and 8 may be formed in a gate shape by a twisting conveyor having a rising portion so as to ensure a space where traversing of a truck is possible.

The circulation path may be enlarged so as to serve also as the communication path so that the empty bobbin can be removed and the tray T can be distributed in the enlarged circulation path.

Furthermore, in the above embodiment, the following is preferable. That is, the transport band 13
When the delivery of the real bobbin B ₁ of a is completed, the insertion of the empty bobbin B ₀ into the transport band 13a is started immediately. As a result, the empty bobbin B ₀ to the one transport band 13a is parallel to the payout period of the real bobbin B ₁ of the other transport band 13b.
Therefore, the empty bobbin B ₀ insertion time can be substantially reduced. Therefore, the amount of the actual bobbin B ₁ stocked on the reserve conveyer 3 can be reduced, and the reserve conveyer 3 can be made compact.

The present invention is not limited to the above aspect, but may be as follows.

The reservoir may store only the actual bobbin, and the actual bobbin may be dispensed from this reservoir to the tray. The reservoir is not limited to the conveyor, and may have a function of simply stocking, and the transport function may be performed by another means. It is also possible not to mix the tray with the actual bobbin and the tray with the empty bobbin in the reservoir. The connection path on the winder side may be a circulation path. To take the tray into the reserve line or to run the circulation path without taking it in,
A guide for directing the tray to the reserve line side is attached to each reserve line inlet of the circulation path so that the tray can be taken into the reserve line when the reserve line is empty, and when the reserve line is full, the tray is full. Alternatively, the tray at the entrance may be obstructed to prevent the tray from being taken into the reserve line and flow through the circulation path.

In summary, according to the present invention, the empty bobbin return path can be straight and the carrying direction can be one direction, and the empty bobbin return path can be simplified.
