2. Description of the Related Art As a conventional roving bobbin conveying device, there is one disclosed in Japanese Patent Laid-Open No. 62-62932 and Japanese Patent Laid-Open No. 62-62933, which is used for each roving machine of a roving machine group. Bypass rails are installed side by side in the middle of the main rail that connects the doffing grenels and the spare shino rails of each spinning fleet of the spinning machine group, and the switching pieces are switched by the action of the cylinder at the branch points of each rail. A bobbin carriage is provided on the doffing gren of all the spinning machines as a standard state of the transfer cycle, and at least one spinning machine's spare Shino rail of the spinning machine group is an empty house without a bobbin carriage. A bobbin carriage with a full bobbin suspended by a doffing grail of a roving frame requires removal, and a bobbin with an empty bobbin hung by a spare shin rail of a spinning frame. When the carriage requests receipt,
Both bobbin carriages are conveyed at the same time, passing by the bypass rail part, the bobbin carriage that hangs the full bobbin hangs to the spare shino rail of the spinning machine in the vacant house, and the bobbin carriage that hangs the empty bobbin hangs the full bobbin. The bobbin carriage was transported to the doffing grail of the roving frame machine, which became an empty house.

However, in the above roving bobbin transport device,
In order to convey the bobbin carriage, it is necessary to control the switching of the switch by the control device, and there is a problem that the cost is high, including the parts such as wiring and piping and construction.
Therefore, there is a switching device submitted by the applicant of the present application in Japanese Patent Laid-Open No. 6-212344, in which a switching piece located at one switching position that connects one branch portion and a merging portion is continuous with the other. When the bobbin carriage enters from the branching portion, it is switched to the other switching position that connects the other branching portion and the merging portion to each other, and is held at the other switching position. There are the following two examples as the roving bobbin transporting device that does not require the switching control of the switch using the switch.

The doffing rail of one roving frame and the spare shino rail of a plurality of spinning frames are connected by the main rail,

[0006]

In the above-mentioned conventional roving bobbin transporting device, the other bobbin carriages are main until the bobbin carriage on the spare shino rail of the spinning frame reaches the doffing gren of the roving frame and returns. Since it is not transferred on the rail, the transfer time is long and the transfer efficiency is poor. Further, in the conventional roving bobbin transfer device, the roving bobbin between the roving machine and the stock rail needs to be transferred by an operator who carries a trolley on which a large number of roving bobbins are mounted, which is an automation level. The roving bobbin was conveyed at a low level.

[0007]

In order to solve the above problems, in the present application, the doffing gren of the roving frame group and the transport rail of the spinning frame group are connected by a main rail, and the switching control is performed in the middle of the main rail. The stock rail group is connected through three unnecessary one-way switches, and the switching control is not required at the branch point between the main rail, the doffing rail and the transport rail, and at the branch point between each stock rail. A roving bobbin transfer device having a high transfer efficiency and a high automation level is characterized by being provided with a switch.
