Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a method for winding a linear body such as a long hose onto a drum, or for supplying the wound linear body to the next process. Regarding equipment.

[Conventional technology]

In the manufacturing process of rubber hoses, etc., first a mandrel is supplied from a drum, and then the final product, the rubber hose, is wound onto the drum.Of course, the hose in the process of being manufactured is wound onto a large drum several times, and then the hose is wound on a large drum several times. It is fed and fed to the next process.

For example, an inner rubber layer is extruded onto a long flexible mandrel made of nylon or the like using an inner rubber extruder, and a winder installed at the rear of the extruder aligns and winds it around a drum. In order to apply a reinforcing layer such as a fiber reinforcing layer to the drum, the drum is removed from the winder, placed on a lift, etc., and moved to the supply side of the braider machine.
After being set in the feeder of the braider machine, the hose is braided while being fed out from the drum, and then the hose is braided and wound in line on the drum using a winding machine installed at the rear of the braider machine. Furthermore,
The drum on which the braided hose is wound to cover the cover rubber layer is carried by lift etc. to the supply side of the cover rubber extruder, transferred to the supply device installed on the supply side of the extruder, and fed out from this drum. Covering is then carried out, followed by vulcanization and other treatments to produce rubber hoses.

Such conventional hose winders and feeders are installed close to each braiding machine and extruder as described above, and drive shafts that receive shafts at both ends of the drums of the winders and feeders. By rotating the drum, the hose could be wound onto the drum or fed from the drum.

In this way, conventionally, each time a hose is wound onto a drum during manufacturing, a winding machine and a feeder to connect it to the subsequent process are placed, and each time the process changes, a lift or clay is used to move the drum one by one. It had to be set on the bearing shaft of the winder or feeder.

[Problems to be Solved by the Invention] In view of the conventional circumstances, the present invention eliminates the trouble of setting a drum in a winding machine or a feeding machine installed in an extruder or braider machine every time a hose is wound up or supplied. It is an object of the present invention to provide a hose winding and supply layer device which can wind up or supply a hose while the drum is placed on a moving cart.
