Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic sleeve changing device for a winding drum of a steel strip winding machine.

[0002]

2. Description of the Related Art As a sleeve mounting device for a steel strip winding machine, there is a sleeve mounting device for a winding machine disclosed in Japanese Utility Model Laid-Open No. 58-51815. This device has a sleeve mount that holds a steel sleeve on a carriage that runs on a rail and that straddles the coil car in the same direction as the coil car that extracts and discharges the coil wound around the drum of the winder. After placing the steel sleeve on the stand, the link and hydraulic cylinder for aligning the steel sleeve and the center of the steel strip winder drum in the height direction, and the height corresponding to the outer diameter of the steel sleeve For center alignment in the center direction,
That is, after centering with a screw and a handle for adjusting the stroke of the hydraulic cylinder, the mounting device is run to the winder side, and the steel sleeve is mounted on the drum of the winder.

[0003]

The sleeve mounting device for the conventional winding machine has the following problems. Since there is only one sleeve holder that holds the steel sleeve on the trolley, in order to attach sleeves with different outer diameters that correspond to changes in the inner diameter of the coil wound by the winder, you must manually operate the handle each time. The centering of the winder drum and steel sleeve must be adjusted.

After the drum of the winder is reduced from the perfect circle, the sleeve is mounted and the coil is wound by enlarging the drum. However, in the case of a thin sleeve, the sleeve is flatly deformed by its own weight, so that the sleeve cannot be mounted. The required clearance between the outer diameter of the drum and the inner diameter of the sleeve must be increased, which increases the expansion / contraction amount of the winding drum.

Since the sleeve holder is held only by the frictional force caused by the weight of the sleeve, the sleeve holder is struck by the error due to the above-mentioned operation and the deformation amount due to the vibration during traveling of the carriage, which causes the sleeve stand to hit the drum drum. Occurs, and there is a risk of the sleeve falling from the sleeve stand.

The coil wound by the winding machine is taken out by a coil car and conveyed to a payout saddle or a payout conveyor, but a large equipment scale and space are required because the sleeve mounting device is installed in the same direction.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art and to provide an automatic sleeve changing device capable of mounting and removing a sleeve at the same time with one device.

[0008]

SUMMARY OF THE INVENTION The technical means of the present invention for solving the above-mentioned problems is to provide a traverse carriage that moves in a direction perpendicular to a winding drum of a winder and a traveling carriage that moves in the winding drum direction. A built-in holding base for holding a plurality of sleeves having different sleeve outer diameters on the traveling carriage, the holding base is divided into two, and a sleeve holding base expansion / contraction device is provided so that the sleeve can always keep a perfect circle. It is characterized in that it is provided with a claw for mounting the sleeve, and a claw for moving up and down by a cylinder for taking out the sleeve.

[0009]

[Operation] When the φ508 mm sleeve is mounted on the winding drum and the φ610 mm sleeve is mounted after the sleeve is removed, the φ508 mm sleeve holder at the standby position is empty, and the φ610 mm sleeve holder is φ
After the 610 mm sleeve is loaded, the traverse carriage is traversed by the operation of the multistage cylinder to a position where the center of the φ508 mm sleeve holder is aligned with the center of the winding drum.

Then, the rotation of the traveling motor causes the rotation shaft to rotate via the sprocket and the chain, and the rotation of the pinion attached to the rotation shaft moves the rack attached to the traveling carriage to advance the traveling carriage to the sleeve removal position. Then, due to the lifting of the holding table elevating cylinder, a uniform gap is secured between the outer diameter of the winding drum and the inner diameter of the sleeve, and the sleeve is held on the holding table. Next, the take-out pawls are lifted by the operation of the cylinder, the take-out pawls are caught by the sleeve end portions, and the withdrawal of the traveling carriage completes the sleeve withdrawal of φ508 mm. Next, the holding platform loaded with a sleeve of φ610 mm is traversed until it coincides with the center of the winding drum, and then the traveling carriage is advanced.
The sleeve is attached to the winding drum, the traveling carriage moves backward, and the sleeve replacement work is completed.

The rubber sleeve holder is semicircular and the lower part is divided, and there is an adjusting mechanism 21 for keeping the rubber sleeve in a perfect circle state. It is provided on the upper surface of the traveling carriage.

[0013]

Since the present invention has the above-mentioned structure and operation, it has the following effects. The removal and mounting of multiple sleeves with different outer diameters according to the inner diameter of the winding coil can be performed automatically at the same time using a single device, which eliminates the need for an operator who was previously engaged in this work. Exchange time can be shortened and work efficiency has improved. The steel strip winding device on the process line is for continuous operation. 2
It is installed on a stand, and by using the equipment space of each winding device, by installing the sleeve exchange device in the cross direction with respect to the traveling direction of the coil car, the traveling stroke of the coil car can be shortened and the equipment cost can be reduced. .
