Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic magazine feeder for a spinning machine.

[0002]

2. Description of the Related Art Recently, roving bobbins have been supplied to spinning machines.
It is done as follows.

That is, a hanger rail is installed around each spinning machine, and a magazine is hanged and supported on the hanger rail so that the magazine can run freely. It is freely suspended and supported. The hanger rail is connected to the side of the roving frame, and the magazine produced by the roving frame is once stored in the stockyard and conveyed from here to each spinning frame. The magazine conveyed to each spinning machine is stopped at a fixed position, and the roving bobbin suspended and supported by the magazine is not removed from the magazine. The roving yarn is then fed until the roving yarn is exhausted. Then, when the roving thread is used up, the empty bobbin is carried out from the spinning machine while being hung in the magazine, and the empty bobbin is removed from the bobbin holder of the magazine and collected by the collecting section of the empty bobbin. The recovered empty bobbin is supplied to the roving machine, and the roving is wound around it to produce a full-filled roving bobbin. On the other hand, an empty magazine is transported to the roving frame side, and is loaded with a full-threaded roving bobbin produced by the roving frame to be transported to a stockyard or a spinning frame. It should be noted that the magazines are connected in the required number in order to simultaneously replace the roving bobbins for all spindles of each spinning machine (for example, 400 to 900 spindles on each side).

Conventionally, the bobbin is carried in and out of the spinning machine by an operator manually pushing the magazine to move the magazine along the hanger rails.

[0005]

As described above, by pushing the magazine by hand, from the roving machine or the stockyard,
The conventional method of carrying in and out of the spinning machine has the following problems. That is, recently, with the introduction of a high-speed spinning machine, the winding weight of the roving yarn per bobbin is increasing, and the total number of spindles of each spinning machine is increasing. Moving the long passage by pushing it by hand puts a lot of labor on the worker, and automation and labor saving are demanded.

The present invention is directed to satisfying the above needs.

[0007]

In order to achieve the above object, the present invention provides a plurality of spinning frame rails arranged along a spinning frame and a plurality of spinning frame rails spaced apart from the spinning frame rail. Full bobbin stock rails and empty bobbin standby rails are connected between each rail, and a connecting rail with a point switching mechanism at the connection point with each rail and bobbin for the number of spindles of one spinning machine are attached and detached. A plurality of magazines that can be divided and supported as much as possible, are connected in a row, and are supported movably on each of the rails, and at appropriate places such as the entrance and exit of each of the rails, are installed so that they can be contacted and separated from the magazine, and when contacted, A magazine drive mechanism that drives one or more magazines in contact with each other to drive the magazine row in forward and reverse directions, and is installed at different starting positions of the rails and at both ends of the magazine row. A detector for stopping the operation of the magazine drive mechanism by detecting passage of the rearmost end in the traveling direction of the magazine row driven by the gazin drive mechanism, and an operation section for starting and manually operating the magazine drive mechanism are provided. An automatic conveyor device for a spinning machine magazine is provided.

The present invention also provides a magazine drive mechanism and a detector in the above-described automatic magazine feeder for a spinning machine.
The bobbin stock rails, empty bobbin standby rails, and connecting rails may be installed and installed only in appropriate places.

[0009]

In the apparatus of claim 1, the magazine drive mechanism at a required position is started by the operation portion to carry out the empty bobbin from the spinning frame rail to the empty bobbin standby rail or from the full bobbin stock rail. Carrying in a full bobbin to the spinning machine rail, and other things, from the empty bobbin standby rail to the full bobbin stock rail, the empty bobbin is removed along the way and the full bobbin is loaded automatically. Alternatively, the detection of the carry-out end is detected by the detector, and the magazine drive mechanism is automatically stopped.

As for the magazine drive mechanism, only those currently required are driven, and the others are stopped. By keeping the magazine driving mechanism in contact with the magazine while stopped, the magazine driving mechanism serves as a stopper that prevents the magazine row from being moved.

According to the second aspect of the present invention, the semi-automatic device is advantageous when the spinning machine is far away from the full bobbin stock rail and the empty bobbin standby rail. That is, the worker goes around each spinning machine to perform post-processes for thread breakage and bobbin replacement work. Since bobbin replacement timing of each machine frame is slightly different, the bobbin of one spinning machine is changed. When exchanging, first, the empty bobbin is carried out and the full bobbin is carried in. At this time, the leading magazine in the magazine row of empty bobbins is pulled and moved to the magazine drive mechanism of the communication rail, and thereafter, the magazine drive mechanism automatically carries out to the empty bobbin standby rail. Then, the full bobbin is automatically conveyed to the position of the spinning machine from the full bobbin stock rail to the position of the spinning machine to some extent, and the operator manually pushes only the final position to complete the loading. Then, the starting ends of the rovings of the full bobbins that have been carried in are connected to the weights, and the operation of the spinning machine is restarted.
