Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for regulating the travel of a blow-off cleaning traveling body for a spinning machine.

[Conventional technology]

The above-mentioned blow-off cleaning traveling body has an endless rail laid corresponding to a group of spinning machines, for example, spinning machines, and blows off and cleans each spinning machine in sequence along this rail. In this case, the spinning machines undergo periodic repairs one after another, and each spinning machine performs doffing work at predetermined intervals.At this time, the entry of the running bodies causes various obstacles, so it is necessary to stop the intrusion of the running bodies. There is. For this reason, temporary measures have been taken to make the traveling body turn around when it reaches the spinning machine (for example, in Japanese Patent Publication No. 43-14977
Publication No.).

[Problem that the invention seeks to solve]

It takes a considerable amount of time for the traveling bodies to make one round of the above-mentioned large number of spinning machines. Therefore, the doffing operation is carried out, which causes the traveling body to move backwards, during which time the doffing operation is completed (normally doffing is completed within 5 to 6 minutes after issuing the doffing forecast), and the spinning machine is moved in the opposite direction. It takes a considerable amount of time to enter.

In particular, when one of the spinning machines in a group is undergoing regular repairs and one of the other spinning machines is doffing, or when two spinning machines are doffing at the same time, only the two spinning machines are reciprocated, and the other spinning machines are Doffing is completed for the spinning machine on the side, and after a considerable amount of time has elapsed, the spinning machine may be passed through and the spinning machines ahead of it may be cleaned.

Originally, the number of running bodies to be handled was determined based on the cleaning cycle time for the spinning machine and the traveling speed of the running bodies, and a large delay in cleaning intervals would result in a large amount of fluff, etc. There are problems such as causing the occurrence of

[Means for solving problems]

The present invention is suitable for short-time stop tables such as doffing.
Rather, the present invention was arrived at by focusing on the fact that it is possible to shorten the loss time for all spinning machines by having the traveling body wait until it stops and restarting the traveling immediately after the end of doffing. The method includes, in a traveling body that runs along an endless rail laid corresponding to a group of spinning machines and performs blow-off cleaning in sequence, a traveling body reversing means for preventing the traveling body from entering each spinning machine; , a running body temporary stopping means, and the running body is turned around by the running body reversing traveling means when the spinning machine is stopped for a long time among a group of spinning machines, and when it is run when the spinning machine is stopped for a short time such as doffing. The present invention is characterized in that the running body is stopped on the entrance side of the spinning machine by body temporary stopping means and is made to wait.

A second aspect of the present invention relates to an apparatus for carrying out the above-mentioned method, which comprises a traveling body reversing means and a traveling body temporary stopping means for preventing the traveling body from entering each spinning machine in the traveling body, and the traveling body reversing traveling means. The means consists of a retractable actuating rod provided at an appropriate position in each spinning machine, and a switching lever provided on the running body that projects into the operating position and engages with the actuating rod to switch the motor circuit between forward and reverse directions, and temporarily stops the moving body. The means includes a transmitting member provided on the running body, a receiving member provided at a suitable location near the entrance of the running body of the spinning machine, and a stop operation circuit for opening and closing the running body drive circuit, and receives a stop signal such as when the pipe is full and a reception signal from the receiving member. Accordingly, the stop operation circuit is opened and the traveling body is stopped.

[Function] When the platform is stopped for a long period of time, such as for periodic repairs, the traveling body is run in reverse. Also, when approaching a short-time stop table such as doffing, the machine stops and waits. After the doffing is complete, the train resumes running. This makes it possible to immediately clean the doffing finishing table and each spinning machine following it.
