Description of the Related Art Conventional technology and its problems Conventionally, a doffing gren arranged at the position of a roving frame and a spare rail arranged at a position of a spinning frame are connected by a main rail, and a bobbin carriage guided by the doffing gren is connected to the roving frame. Hanging the roving bobbin that was fried in
This bobbin carriage travels along the main rail and is transported to the spare rail of the spinning machine. Conversely, the bobbin carriage that suspends the empty bobbin (including the residual roving bobbin) at the spinning machine position is used as the spare rail. There is known a roving conveying system for conveying from a to doffin greil. In this roving yarn conveying system, the number of spindles of the roving machine is generally 1 / the number of spindles of the spinning machine.
Set it to be the same as 4 or half of it, equip the bobbin carriage with the same number of bobbin hangers as the number of spindles of the roving machine, and set one roving bobbin to be fried in the roving machine.
Hanging all on the bobbin hanger of the book bobbin carriage,
One or two bobbin carriages are carried into the spare rail. However, in actual spinning factories, there are roving machines and spinning machines with various numbers of spindles, and the number of spindles of the spinning machine is not an integral multiple of the spinning machine, but may be 1.5 times or 2.5 times, for example. Even in such a case, it has been desired to convey the roving bobbins or the empty bobbins from the roving frame to the spinning frame or vice versa by the bobbin carriage.

Therefore, the conventional Japanese Unexamined Patent Publication No. 62-110928 and Japanese Unexamined Patent Publication No. 1-9243
As disclosed in Japanese Patent Publication No. 6, a bobbin carriage element (conveyor) is provided with a bobbin hanger having the greatest common divisor of the difference between the number of spindles of the roving frame and 1/4 of the number of spindles of the spinning frame. A connection in which a plurality of roving bobbin transport units) are connected to each other and the bobbin carriage elements are separated from each other or the bobbin carriage elements are connected to each other at a position where the bobbin carriage is transported from the roving frame to the spinning frame or vice versa.

The detection switches 81 and 82 for detecting the () are provided. In the control box (not shown), the connected bobbin carriage elements 12a and 12b conveyed from the doffing rail 5 into the full bobbin rail 7 are moved to the innermost part of the spare rail 6 of the spinning machine 3a or the spinning machine 3c. In the case of transporting, that is, in the case where separation is necessary, after the detection switch 71 detects a dog (not shown), the transfer device 9 on the full bobbin rail 7 is temporarily stopped,
After that, only the transfer device 9 on the spinning machine side from the cam member 65 is operated to bring only the bobbin carriage element 12a into the required spare rail 6, and the bobbin carriage element 12b is moved this time by the command of the confirmation switch (not shown). The transfer is controlled to be carried to the required spare rail 6, and when the separation is not necessary, it is controlled to be carried to the required spare rail 6 by each transfer device 9 as it is without stopping. Even when the separation is not necessary, both bobbin carriage elements 12a and 12b may be temporarily stopped and then conveyed together with both. When the connecting portion of the bobbin carriage element in the connected state reaches the position of the cam member 65, the locking arm 45 is rotated by the cam member 65 against the bias, and the connected state is released.
With the contact plates 37, 38 in contact, the bobbin carriage element
Since both 12a and 12b are moved, the locking arm 45 is moved to the cam member 65.
When it is separated from the locking arm 45, the locking arm 45 is rotated in the urging direction to lock the locking portion 45.
b again locks the locking piece 37a and returns to the original connected state. Further, when the bobbin carriage elements 12a and 12b on which the empty bobbin is suspended are taken out from the spare rail 6, the control box (not shown) is provided with the bobbin carriage element 12 in the separated state.
In the case of a and 12b, first, the bobbin carriage element 12b is taken out from the spare rail 6 and conveyed from the main rail 4 to the empty bobbin rail 8, and when the detection switch 82 detects a dog (not shown), the transfer device at that position. 9 is stopped and stopped at the position indicated by the phantom line in the figure, then the bobbin carriage element 12a is conveyed to the empty bobbin rail 8, and the detection switch 8
1 detects the dog (not shown) and controls the operation of each transfer device 9 to stop. This allows empty bobbin rail 8
The bobbin carriage element 12a that has been carried in has its locking piece 3
7a abuts on the guide slope 45a of the locking arm 45 and rotates it against the biasing force, and the abutment plate 37 abuts on the abutment plate 38 to engage the locking arm.

It is connected to 2b. After that, the transfer device 9 is operated to apply the roving stripper 14. In the case of the connected bobbin carriage elements 12a and 12b, the bobbin carriage elements 12a and 12b are conveyed from the spare rail 6 to the empty bobbin rail 8 and are controlled so that the roving stripper 14 is put on without stopping.

Next, FIG. 7 shows a different embodiment of the connecting and disconnecting device 30,
The same components as those of the above-described embodiment are designated by the same reference numerals, and the duplicated description will be omitted. In the figure, the operating arm 52e is provided on the side opposite to the locking arm 45 with respect to the pivot axis, and a cam follower body 84 having chevron-shaped guide slopes 84e, 84f is provided on the outer side of the operating arm 52e so as to project. On the other hand, the guide slopes 65b at both ends of the cam member 65 are inclined upward so that the guide slopes 84e and 84f can be guided. The connecting and disconnecting device 30 thus configured
Even at e, by engaging the cam follower body 84 with the cam member 65, the locking arm 45 can be rotated against the urging force and can be separated. This connecting and disconnecting device 30
In order to carry out e, it is necessary to provide a cam member 65 for connection so that the separated bobbin carriage elements 12a, 12b can be connected on the empty bobbin rail 8, for example, as shown in phantom in FIG. Is.

As described above, according to the present invention, one end of the bobbin carriage element on the connecting side is provided so as to swing vertically, and is engaged with the other locking piece of the connecting end. When the bobbin carriage travels, the operating arm integrated with the locking arm engages with a cam member fixed in the middle of the transport rail, so that the locking portion is engaged. Since the bobbin carriage element is moved so that the connecting portion of the bobbin carriage element comes to the position corresponding to the cam member, only one bobbin carriage element is moved with respect to the other. By separating the two, the bobbin carriage can be separated from the bobbin carriage only by controlling the travel of the bobbin carriage without using a separate driving device for the bobbin carriage separating device as in the conventional case. It has the advantages that it can be separated into elements, the entire device has an extremely simple structure, can be implemented inexpensively, and that the number of parts is reduced and failures are reduced. Further, since the bobbin carriage is separated by the engagement of the fixed cam member and the operating arm that moves relative to the fixed cam member, the cam surface of the cam member is kept in the separated state in the traveling direction of the bobbin carriage for a long time. With such a configuration, there is an advantage that the connecting portion of the bobbin carriage can be reliably separated even if the stopping accuracy with respect to the cam member is low. Moreover,
In the present application, even if the cam member is fixed,
By moving the bobbin carriage elements at the same speed, there is the advantage that the bobbin carriage can be passed through without disconnecting. Further, in the present application, since the vertical positioning member is provided on the supporting member at the end of the bobbin carriage element on the connecting side, the bobbin carriage may vibrate up and down while traveling in the connected state along the transport rail. However, there is also an advantage that the connected state of the locking arm and the locking piece is maintained and the locking arm does not come off.
