Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bobbin conveying device that receives a fully wound bobbin from a winder or the like and conveys it to a processing machine for the next process.

Generally, in the fiber manufacturing process, the fully wound bobbins formed are loaded onto a trolley and transported to the next processing machine, but conventionally, the fully wound bobbins transported in this way are manually set on a creel after being processed one by one. was.

However, in recent years, a so-called creel truck system has been adopted for transporting such fully wound bobbins to a processing machine, in which the cart carrying the fully wound bobbin is directly guided to the creel section of the processing machine. The process and the post-processing process are connected by a creel cart, and the creel cart is directly transported to the winding machine of the yarn manufacturing process, where the full bobbin formed is loaded and transported in this state for post-processing. In this process, the film is introduced into the creel section of a drawing machine.

Although such a creel truck system is very rational and has many excellent advantages, on the other hand, it has the following major drawbacks.

In other words, in the case of a twisting machine with a creel stand installed at the top, the spacing between the spindles is much narrower than that of a spinning winder, and prevents mutual contact when the creel stand is buttoned to unwind the yarn. Therefore, the yarn bobbins are arranged on the creel so that the horizontal spacing is wider than the spacing between the spindles of the stretching machine, and the yarn bobbins are arranged in several stages at regular intervals in the vertical direction by shifting their positions.

This arrangement is the same in the case of a drawing machine that processes fiber bundles on the same floor.

For this reason, the pegs for supporting the raw yarn bobbin of the creel cart are arranged as described above, and the creel cart is moved in this state from the spinning and winding process to the stretching and twisting process.

However, when transporting the reel cart to the winding process and loading fully wound yarn bobbins one after another, the peg arrangement is arranged in several rows above and below, making it difficult to transfer the yarn bobbin from the winding machine. This method has the drawbacks that the work is complicated and time consuming, and it is difficult to accurately move the cart to the delivery position.

It is also conceivable that the delivery of the yarn bobbin could be carried out by an automatic doffing machine or the like that is movably disposed in front of the winding machine. It is dangerous to work because it occupies a large space in front of the winder with attached equipment such as multi-tiered bobbin trolleys and other attached equipment outside the main body of the machine, and has the disadvantage of being subject to severe space constraints. It is expensive and extremely troublesome to repair and manage.

In particular, in the case of large packages where the winding amount is several tens of kilograms, the above-mentioned tendency is severe because the equipment becomes huge.

The present invention has been made in view of the current situation, and includes a creel unit equipped with a plurality of pegs for loading the fully wound bobbin into a device that dots the fully wound bobbin from the winder and transfers it to the next process. , a self-propelled vehicle on which the unit is placed and moves and stops at a fixed position along the front of the winder, and a creel knitting machine that has a multi-stage support shelf, and the unit is placed on the support shelf to be subjected to the next process such as a drawing machine. It consists of a creel truck as a component, and is further characterized in that the self-propelled vehicle or creel truck is stored at the end of the traveling line of the self-propelled vehicle, and the unit is delivered via a lifting means that moves up and down. This is a fully wound bobbin transfer device.

At the same time, the protrusion 81 hits the limit switch 33, and the signal closes the compressed air supply valve of the air motor, completely stopping the self-propelled vehicle.

This position is such that the peg 11 of the creel unit 10 corresponds to the bobbin holder 3 of the winding unit 2 to be doffed, so when the fluid cylinder 7 is actuated by the next operation, the bobbin holder 3 Rotate downward to the same angle as the peg and face it.

During this time, the spun yarn is cut by the female yarn cutter shown in the figure and sucked into the aspirator, and the bobbin holder 3 stops rotating.

Thereafter, the pusher 8 is projected to press the bobbin end face of the yarn bobbin 4a, and at the same time, when the bobbin holder 3 is released, the yarn bobbin 4au is given an initial velocity and moves under its own weight to the peg 11.

In this case, instead of rotating the bobbin holder 3, the peg 11
It is also possible to have the bobbin holder 3 on the same level as the bobbin holder 3 and to transfer it using a pusher.

Next, by pressing a button on the operation panel, the self-propelled vehicle 20 travels toward the next winding unit 2, and in the same manner as described above, this time the empty peg 11 is placed in a position corresponding to the bobbin holder 3. It stops and the yarn bobbin is doffed.

During this time, an empty bobbin is inserted into the doffed winding unit 2 and a thread is threaded thereon.

When the transfer of the yarn bobbin 4a to all the pegs 11 on one side is completed in this way, the motor 43 is driven, the turntable 44 rotates half a turn, and the empty peg 11 on the other side is transferred to the bobbin holder 3 of the winding unit 2. They stop at the facing position, and the yarn bobbin is doffed as described above.
