Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is to rotate a rod-shaped elongated body such as a steel rod or an iron mandrel having a rubber hose on its outer periphery in a circumferential direction, The present invention relates to a device for transferring in the direction.

[Conventional technology]

Conventionally, a rod-shaped elongated body as described above is rotated in the circumferential direction,
As a device for transferring in the longitudinal direction, for example, in the production of rubber hoses, the outer diameter is 50 to 200 mm and the length is 5 to 25 m.
A rubber hose, etc. is applied to the outer circumference of the iron mandrel, and this long body is supported by a group of idler rollers in which a plurality of pairs of freely rotatable spherical idler rollers are linearly arranged, while the long body is circled. In the case of rotating in the direction, one end thereof is held by a chuck or the like and rotated by a rotation drive device provided separately from the idler roller group. Further, when the long body is transported in the longitudinal direction, it is manually pushed and moved on the idler roller group in the longitudinal direction.

For example, in cloth vulcanization of a rubber hose, two groups of the above idle rollers are arranged at intervals and two mandrels and the like are arranged.
A rubber hose is manufactured while reciprocating in the longitudinal direction between the idle rollers of the group. Explaining in one example, the rubber hose vulcanized on the outer periphery of the mandrel is placed on one idler roller group from the vulcanized mountain with a hoist or the like, and is placed in the middle of both idler roller groups. The tape is wound from the outer periphery by the installed unwrapping machine, and at the same time, the rubber hose and the mandrel are rotated and transferred to the other idle roller group. Therefore, while holding the other end of the rubber hose with a chuck provided at the far end on the other side of the other idling roller group and rotating it on the spot, a cutting machine installed in the middle of both idling roller groups is used to cut the rubber hose. Cut one end. After that, the mandrel and the rubber hose are manually transferred in the longitudinal direction, returned from the other idling roller group onto the one idling roller group, and the chuck provided at one far end of the one idling roller group. The rubber hose is gripped, and the other end of the rubber hose is cut by the above cutting machine while rotating the rubber hose on the spot to obtain a rubber hose having a desired length.

In this way, by installing an unwrapping machine or cutting machine in the middle of both idle roller groups, unwrapping and cutting operations can be performed efficiently, but the end of the rubber hose can be gripped. The chuck for rotating the machine inevitably has to be at the far end from the unwrapping machine or cutting machine, and therefore the worker has to move a considerable distance each time the chuck is operated, which reduces workability. The result was a great loss.

It is conceivable to rotate the idler roller group in the longitudinal direction and the circumferential direction of the elongated body, but the structure of the entire device including the drive system becomes extremely complicated, and practical application is difficult.

[Problems to be solved by the device]

In view of the above-mentioned conventional circumstances, the present invention is a rotation / transfer device for a long body that can transfer a rod-shaped long body such as a mandrel in the longitudinal direction with a simple mechanism and can also rotate it in the circumferential direction. The purpose is to provide.

It features an endless belt.

〔Example〕

 A specific example of the device of the present invention will be described with reference to the drawings.

The apparatus shown in FIG. 1 is an apparatus for rotating and transferring the mandrel 1 used for rubber hose manufacturing, and the base 2 is directly fixed to a base material such as an upper wall or a rail fixed to the base material. A hollow box-shaped support portion 4 is suspended vertically below the base portion 2 by three rods 3 so as to be movable in the horizontal direction. A vertical drive unit 5 composed of a cylinder is installed on the base unit 2, and by setting the drive rod thereof to one of the rods 3,
The support part 4 can be moved up and down with respect to the base part 2.

At the center of the lower surface of the support portion 4, a support shaft 6 extends downward and is rotatably provided with respect to the support portion 4. One end of the crank rod 7 is supported on the upper end of the support shaft 6 protruding into the support portion 4,
The other end of the crank rod member 7 is connected to a drive rod of a rotary drive device 8 composed of a cylinder horizontally provided on the side surface of the support portion 4, and the reciprocating motion of the crank rod 7 causes the support shaft 6 to move 90 °.
It is designed to rotate back and forth by only °. The rotation of the support shaft 6 is performed by combining a rack provided on the drive rod of the cylinder with a pinion provided at the upper end of the support shaft 6,
Other devices are also possible.

A rotation base 9 is fixed to the lower end of the support shaft 6, and the rotation base 9
On the lower side, two rotary shafts 10 are supported in parallel with each other with a space therebetween, and a belt 12 of a rotary drive device 11 composed of a motor fixed on the upper side of a rotary base 9 is hung on one rotary shaft 10. It has been passed. Collared rollers 13 are fixed to substantially the center of each rotary shaft 10, and are arranged side by side in the direction orthogonal to the rotary shafts. Further, belt pulleys 14 are attached to both ends of both rotary shafts 10, and endless belts 15 are laid between the belt pulleys 14 facing each other of both rotary shafts 10 in parallel with the two rollers 13 with flanges. I have passed it.

[Action]

Next, the operation of the above rotation / transfer device will be described in the case of cloth vulcanization of a rubber hose.

Two idle roller groups in which two freely rotating idle rollers 16 are linearly arranged are installed linearly at two intervals. An unwrapping machine and a cutting machine are installed, and the above-mentioned rotation and
A transfer device is provided. In a normal state, the roller 13 with a collar and the endless belt 15 of the rotation / transfer device are free to rotate freely.
Have been lifted above.

A rubber hose vulcanized on the outer circumference of the mandrel 1 is placed on one idler roller group by a hoist, and the tape around the hose is wound by the unwrapping machine as described above, and the rubber hose and the mandrel 1 rotate. While moving to the other idle roller group.

Therefore, when the endless belt 15 of the rotating / transporting device holds the turntable 9 in the direction orthogonal to the longitudinal direction of the mandrel 1, and the supporting unit 4 and the turntable 9 are lowered by the vertical drive device 5, As shown in FIG. 2, the center of the two endless belts 15 is located under the turntable 9 from above and the mandrel 1
Abut the rubber hose on the outer circumference. When the rotary shaft 10 is rotated by the rotary drive device 11 in this state, the mandrel 1 and the rubber hose can be rotated on the idler roller 16 in the circumferential direction. In this way, one end of the rubber hose is cut by the cutting machine while rotating the rubber hose in the circumferential direction on the other idler roller group.

Next, after the support 4 and the turntable 9 are pulled up by the vertical drive unit 5 to separate the endless belt 15 from the rubber hose, the support shaft 6 is driven by the rotary drive unit 8 via the crank bar 7 to rotate the support shaft 6. Rotate the moving base 9 by 90 °. The supporting unit 4 is lowered again by the vertical driving device 5, and the rotary table 9 is lowered accordingly, so that the two rollers 13 with flanges come into contact with the outer circumference of the rubber hose from above as shown in FIG. Therefore, when one of the rotary shafts 10 is rotated by the rotary drive device 11, the other rotary shaft 10 connected by the endless belt 15 is rotated.
Since it also rotates, the two rollers 13 with ribs can be driven to transfer the mandrel 1 and the rubber hose on the idler roller 16 in the longitudinal direction. In this way, the mandrel 1 and the rubber hose are moved from the other idler roller to the one idler roller group and stopped at a predetermined position.

Then, the vertical drive unit 5 pulls up the rotary base 9 to separate the flanged roller 13 from the rubber hose, and then the rotary drive unit 8 rotates the rotary base 9 to the original position by 90 °. Further, the rotary table 9 is lowered by the vertical drive device 5, and the central portions of the two endless belts 15 under the rotary table 9 are again brought into contact with the rubber hose on the outer periphery of the mandrel 1 from above as shown in FIG. . In this state, by rotating the rotary shaft 10 by the rotary drive device 11 and rotating the mandrel 1 and the rubber hose on the idler roller 16 in the circumferential direction, the other end of the rubber hose is cut by the cutting machine. A rubber hose having a predetermined length can be obtained.

Finally, the vertical driving device 5 raises the rotary table 9 and the like to the original position, and waits for the next mandrel 1 and the rubber hose.
