DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for continuously and automatically supplying a long coil wound in a coil shape.

[0002]

2. Description of the Related Art For example, in the case of a hose with metal fittings, after a long hose is continuously extruded and vulcanized, the hose is continuously taken out from one end side in a coiled state. It is customary to cut the product by a cutter at regular intervals and attach a metal fitting to the end to form a hose assembly (assembled product).

[0003] In supplying a coiled long hose to a cutting machine, a worker manually sets the end of the long hose to a hose feed mechanism, and supplies a single coiled hose. When the cutting was completed, the operator again set the end of another coiled hose.

[0004] However, when the hose is supplied and the subsequent cutting is performed by such a method, there is a problem in that it is necessary to manually set the end of the hose every time the processing of one coil is completed.

[0005]

The device of the present invention has been devised to solve such problems. The gist of the device is as follows: (a) a long table provided with a rotary table and wound in a coil shape; A plurality of transfer pallets which move along a predetermined transport path with the hose placed on the rotary table; and (b) a take-out side end of the coil-shaped and wound hose provided on the transfer pallet. (C) moving the plurality of transfer pallets one after another along the transport path, stopping at a take-out station, and stopping by the end holding means. Transport means for positioning the end of the hose held in position at a predetermined take-out position, (d) a hose feed mechanism arranged near the take-out position and feeding the hose, and (e) the take-out position Hose end positioned at It is to have a set means for automatically set to the hose feed mechanism taken from the end supporting means.

[0006]

In the apparatus according to the present invention, when a long hose wound in a coil shape is placed on a rotary table of a transfer pallet, the transfer pallet is transferred to the take-out station by the transfer means. At this time, the take-out end of the coiled long hose is held in position by the end holding means, and when the transfer pallet reaches the take-out station, the end is taken off. It is located at a predetermined removal position.

[0007] Then, the setting means receives from the holding means the end of the hose which is held in the fixed position and is supplied to the hose feed mechanism. The hose feed mechanism having received the supply at the same end feeds out the same and supplies it to the next process such as a hose cutting process.

On the other hand, the empty transfer pallet is discharged from the take-out station, a new transfer pallet carrying a coiled hose is brought to the take-out station, and the same operation as above is performed again. Hose is automatically sent out.

According to the apparatus of the present invention, by taking the end of a coiled long hose at a fixed position, the end can be automatically taken out and set in a feed mechanism. As a result, a long hose wound in a coil shape can be continuously taken out and supplied between the coils, and automation of hose production becomes possible.
