The cam member 65 is provided with a certain length in the rail direction so that the bobbin carriage elements 12a and 12b can be separated over a wide stopping range, but the length can be set as appropriate.

Furthermore, B is a connection location provided during the return transport of the bobbin carriage 11, which is located in front of the roving stripper 14 at the empty bobbin rail 8 position in the drawing. On the empty bobbin rail 8, there is a detector 82 that detects that the locking arm 45 of the bobbin carriage element 12b has been transferred to the connection position B and issues a signal, and a locking piece 37a of the bobbin carriage element 12a is placed in the connection position B. A detector 81 that detects the transfer and issues a signal is provided. These detectors 82.81 are for example bobbin carriage elements 12b, 1
This is achieved by a detection switch that detects a dog (not shown) attached to 2a.

When this detector 82 emits a detection signal, the control device 10
0 is the bobbin carriage element], the operation of the transfer device 9 that is holding and conveying the bobbin carriage element 2b is stopped, and the bobbin carriage elements 12a and 12b are moved to the connection position B with the contact plates 37 and 38 of the bobbin carriage elements 12a and 12b in contact with each other. It is designed to stop.

Next, the operation of the above configuration will be explained.

First, with the bobbin carriage 11 positioned on the doffing rail 5, the braided yarn bobbin is doffed from the roving frame 1 using a well-known doffing device, and all of the braided yarn bobbins are transferred to the bobbin hanger of the bobbin carriage 11-. 15.

At this time, for example, when there is a signal requesting a roving bobbin from the spinning machine 3a, the control device 100 switches the point switching device 70 so as to guide the spinning bobbin to one of the spare rails 6 of the spinning machine 3a, and then the corresponding dotting rail. 5 and the corresponding spare rail 6 and main rail 4 positions (excluding the similar empty bobbin rail 8 position) operate the feeding devices 9 to move the bobbin carriage 11 from the dotting rail 5 to the main rail 4.
Thereafter, it is conveyed in a relay manner by the feeding device 9,
The bobbin is transported to the full bobbin rail 7. During the above-mentioned transport, the two bobbin carriage elements 12a, 12b are attached to the support member 34.3.
5, the relative movement between the two sides is prevented by the positioning portion 40, so even if the transport rail 10 vibrates vertically when passing through a joint, the locking arm 45 and the locking piece 37a will not disengage. Prevented.

The bobbin carriage 11 is conveyed to the full bobbin rail 7 by the feeding device 9, and the coupling tool 30 of the bobbin carriage 11
When the is transferred to the separation position A, the detector 7↓
detects it and sends out a detection signal. Based on the detection signal, the control device 100 temporarily stops the operation of the feeding device 9 at the full bobbin rail 7 position, stops feeding the bobbin carriage 11, and positions the coupling tool 30 at the disconnected position A. Further, when the coupling tool 30 of the bobbin carriage 11 is moved to the disconnection position A, the tip portion 52 of the operating arm 52 of the coupling tool 30
e is guided by the guide slope 65b of the cam member 65 and rides on the cam member 65, and the locking arm 45 is swung against the urging force of the spring 50, so that the locking portion 45b and the locking piece 37 The disengaged state is maintained. After the feeding device 9 is stopped, only the feeding device 9 located closer to the spinning machine than the separation position A of the full bobbin rail 7 is operated again. As a result, only the separated front bobbin carriage element 12a is transferred in a relay manner and carried into one of the spare rails 6. Next, the control device 100 switches the point switching device 70 so as to guide the spinning frame 3a to the other spare rail 6, and then also switches the point switching device 70 so as to guide the spinning frame 3a to the other spare rail 6. Activate.

As a result, the rear bobbin carriage element 12 is separated.
b is transferred in a relay manner and carried to the other spare rail 6. When the bobbin carriage element 12b is transferred toward the spinning machine 3a, the operating arm 52 and the cam member 65 are disengaged, and the locking arm 45 is brought into contact with the locking piece 38a and directed forward approximately horizontally. The position is restricted to the state in which it was. In the above case, the signal from the detector 71 may be used to stop only the feeding device 9 on the roving machine side from the separation position A, and to perform separation without stopping the feeding device M9 on the roving machine side from the separation position A.

Next, when there is a signal requesting a roving bobbin from the spinning frame 3b, and the bobbin carriage 11 with the bobbin suspended at the dotting rail 5 position is to be transferred to the spare rail 6 of the spinning frame 3a, first The control device 100 switches the point switching device 70 so as to guide the spinning frame 3b to one of the spare rails 6, and then switches the point switching device 70 to the corresponding dotting rail 5,
The feed device 9 located on the main rail 4 and the corresponding spare rail 6 is operated, but in this case there is no need to separate the bobbin carriage 11, so the detector 71 detects the bobbin carriage 1 at the separation position A. The feed device 9 continues feeding without stopping the operation even when the feed device 9 is in use. As a result, the bobbin carriage 11 moves to the coupling tool 3 at the disconnection position A.
The operating arm 52 of No. 0 is swung by the cam member 65 and the engagement between the locking portion 45b and the locking piece 37a is disengaged, but when the operating arm 52 passes through the separation position A, the operating arm 52 is disengaged from the cam member 65 and the locking portion is disengaged. 45b engages with the locking piece 37a again, and is carried into one of the spare rails 6 of the spinning frame 3b while maintaining the connected state. Transferring the bobbin carriage 11 to the other spare rail 6 of the spinning frame 3a is carried out in the same manner as described above.

Next, when carrying the bobbin carriage 11 to the spare rail 6 of the spinning fi3c, first cut off the bobbin carriage 11 at position A, and then move the bobbin carriage 11 to the front bobbin carriage. Element 12a
into one spare rail 6, the rear bobbin carriage element 12b into the other spare rail 6, and then into the spare rail 6 of the spinning frame 3b, without separating the bobbin carriage 11. transport it to the spare rail 6.

Next, when returning the bobbin carriage elements 12a, 12b with empty bobbins suspended from the spare rail 6 position of the spinning frame 3a to the dotting rail 5, the corresponding spare rail 6, main rail 4, and empty bobbin rail 8 are feeding device 9 located
is activated, one bobbin carriage element 12b is first carried into the empty bobbin rail 8, and when the locking arm 52 of that bobbin carriage element 12b is positioned at the connecting position B, the detector 82 detects that bobbin carriage element 12b. Upon detection, a signal is generated, and the operation of the feeding device 9 that clamps the bobbin carriage element 12b is stopped to stop the movement of the bobbin carriage element 12b (7), and the locking arm 5 is stopped.
2 at connection position B. Next, the other bobbin carriage element 12b is transferred to the empty bobbin rail 8, and the locking piece 37a of the bobbin carriage element 12a is at the connection position B.
When the bobbin carriage element 12a is located at the position, the detector 81 detects the bobbin carriage element 12a and generates a signal, which causes the feeding device 9 to stop operating and stop the movement of the bobbin carriage element 12a, and at that moment the bobbin carriage element 12a is stopped. The piece 37a is the locking part 4
5b, and the bobbin carriage elements 12b, 12a are connected to each other. Thereafter, the bobbin carriage 11 is transferred to the roving stripper 14, and then the feeding device 9 located on the dotting rail 5 corresponding to the main rail 4 is operated to carry it to a predetermined dotting rail.

Next, FIG. 6 shows a different embodiment of the connector 30, and the same components as in the above embodiment are denoted by the same reference numerals, and redundant explanation thereof will be omitted. In the figure, the operating arm 52e is provided on the opposite side of the pivot 46 from the locking arm 45, and the operating arm 52e
A cam follower body 84 having mountain-shaped guide slopes 84e and 84f formed thereon is protrudingly provided further outside of the cam follower body 84e. On the other hand, the guide slopes 65b at both ends of the cam member 65 are the guide slopes 84e, 84.
．． It is slanted upward so that it can guide f. In the case of this coupling device 30e, in order to couple the separated bobbin carriage elements 12a, 12b on the empty bobbin rail 8, it is necessary to provide a coupling cam member 65 at the coupling position B. In the present application, a cylinder or the like is used to move the cam member 65 to a position where it can engage with the operating arm 52 when disconnection is necessary, and to a retracted position where it does not engage with the operating arm 52 when disconnection is not necessary. It may be set in The locking arm 52.52e can also be operated by other configurations of disconnection devices, such as actuating members actuated by cylinders or solenoids.
It may be configured to operate.

Effects of the Invention As described above, in the present invention, the bobbin carriage is transferred in a relay manner by a feeding device, and the transfer of the bobbin carriage is stopped when the coupling tool is located at the separation location to separate the coupling tool. Since then, the front bobbin carriage and the rear bobbin carriage were conveyed separately, so even if the number of spindles on the spinning frame was not an integral multiple of that on the roving frame,
Full bobbins doffed on the roving frame can be easily and automatically transported to the spinning frame position, saving labor in transport work.In addition, the bobbin carriage can be separated in a short time during transport on the main rail, increasing transport efficiency. This has the advantage that it can be easily implemented, and the structure of the conveying device can be simplified and implemented at low cost.
