Description

Detailed Description of the Invention 3. Detailed Description of the Invention Industrial Field of Application The present invention is directed to a spinning machine that moves along the edge of a spinning machine group in which a large number of spinning machines are arranged side by side and is connected to a spinning machine that requires five operations. The present invention relates to a work machine for a spinning machine that starts work by confirming a work start signal after the work has been completed.

2. Description of the Related Art Conventionally, it is well known that, as the above-mentioned working machine, there is, for example, a wagon-type doffing machine in a spinning machine. This wagon-type doffing machine is equipped with the doffing machine itself on both sides of a carrier that moves between the frames of the spinning machine, and moves between the machines along the edge of the frame of the spinning machine group, requesting doffing. The spinning machine detects the full tube warning light on the spinning machine and stops at the end of the spinning machine, then checks the full tube lamp (work start signal) and performs the doffing operation.

Problems to be Solved by the Invention According to the conventional technology, the wagon-type doffing machine stops at the end of the spinning machine where the doffing request is issued and waits for the full tube lamp to light up. For example, if the working machine cannot confirm that the full-tube lamp is lit due to reasons such as the full-tube lamp being damaged or burnt out, or the spinning machine not operating properly and the bobbin rail not descending to a state where it can be doffed, the machine will remain at the end of the machine. There were problems such as the spinning machine remained stationary, and would not move even if there was a request for doffing from another spinning machine, reducing the doffing efficiency of the work machine.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a work machine with an alarm output means, and includes in the control circuit of this alarm output means the information on the work machine from the time it is connected to the previous spinning machine. The present invention is characterized in that a timer for setting a waiting time is incorporated, and the alarm output means is configured to operate when a work start signal from the spinning machine is not detected within the waiting time after the working machine is connected.

Effects According to the above configuration, a spinning machine in a group of spinning machines that requires work such as a request for doffing is joined, and from the time of joining to a spinning machine that is required to perform work such as a request for doffing, the processing is performed from the spinning machine side during a predetermined waiting time set in advance by a timer. If the work start signal is not detected, an alarm is issued and the worker is informed that there is an abnormality in the spinning machine or working machine that has been joined, and that the work cannot be carried out despite joining, allowing the cause of the abnormality to be quickly removed. .
