Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roll changing device, and more specifically to a roll changing device that can efficiently replace a scratched or damaged roll with a new roll when the number of ends of a steel cord changes. This relates to a switching device.

Rubberized steel cords are generally used for tire components such as breakers and carcass.

By the way, in the conventional manufacturing of rubberized steel cords, multiple steel cords are sent out in parallel and the number of ends is pulled using a thread roll with multiple grooves, and then this is calendered. The steel cord is fed into a roll and rubberized on the top and bottom surfaces of the steel cord. However, if the number of ends of the steel cord changes, if the thread roll gets scratched during manufacturing, or if the thread roll is damaged, the thread roll must be replaced each time. The work was done by using a chain block, etc., to hang hooks on both ends of the thread roll, and then replacing it with a new thread roll.However, the above-mentioned thread roll replacement work required a worker with at least 2 Å or more. The work efficiency is extremely poor because the thread roll has to be attached with a There was a problem in that the transport work was extremely dangerous due to the considerable weight.

This invention was devised by focusing on the conventional problems, and its purpose is to replace the rolls safely and efficiently, which requires a lot of effort and time. The present invention provides a 1:1 exchange device.

In order to achieve the above object, the present invention includes a roll exchange mechanism that removably clamps both ends of the roll and carries it in and out of a predetermined position on a support frame erected on both sides of the roll. Roll exchange position P of the exchange mechanism,

Next, the replacement work of the thread roll 30 having the above-mentioned configuration will be explained.

First, a situation occurred where the thread roll 30 was damaged and had to be replaced. 11.1. Replace the new thread roll 30 housed in the roll stock rank not shown. The roll clamp 1 of at least one of the upper stage or the lower stage of the trolley 150 (lower stage in this embodiment) is taken into the roll clamp 1 (io, 170) and clamped,
The roll exchange device 10 is transported to a predetermined position.

Next, the moving member 53 holding the thread roll 30 is moved about the shaft 52 by contracting the drive cylinder 55 of the roll changing mechanism 50 [rotated clockwise along the trace G, and guided At a predetermined position of the rail device 100, tighten the shaft end 32 of the thread roll 30 held in the grooves 57a, 57b of the fitting holding part 54 using the screw 54.
It can be released by loosening c. This thread roll 30 is then transferred to the rear end side 110b of the turning rail 110.

Next, after the thread roll 30 is transferred onto the turning rail 110, the turning cylinder 113 is operated to extend and pushes the rear αj11 side 110b of the KIi turn rail 110 upward.
Then, the thread roll 30 is transferred onto the fixed rail 120 while rotating due to its own weight.

The thread roll 30 placed on the fixed rail 120 is transferred by a worker through the swing rail 130 while rotating the thread roll 30 to the two-stage roll clamp mechanism 160 of the roll exchange cart 150. After the worker has positioned the clamp handle 253 in the specified position,
is operated to lower the movable clamper 220 and firmly clamp the shaft end 31 of the thread roll 30 between it and the fixed clamper 210. Also, during this operation, the swing rail 1
30 is placed by rotating it upward so as not to get in the way.

Next, in order to position the new thread roll 30 housed in the lower stage of the roll exchange cart 150 on the upper stage side, the handle 233 of the turning mechanism 230 is operated to move the worm 232.
Worm wheel 231. The rotating plates 200a and 200b are rotated 180 degrees via the rotating shaft 190, and the damaged thread I:1-roll 30 is placed in the lower part 11, and the new thread roll 30 is placed in the upper part. From this state, the clamp handle 253 is rotated to release the clamp on the thread roll 30, and the swing rail 130 is also pivoted to its original horizontal state.

The thread roll 30 is taken out from such a state, transferred along the swing rail 130 and the fixed rail 120, and transferred to the swing rail 10''. Then, the rotation cylinder 113 is retracted to move the thread roll 30 toward the rear end side 110b, and the clamp plate 54a and opening/closing plate 54b are fitted together by force A (1 of M holding portion s4).
The shaft end 32 of the threaded throat roll 30 is fitted into the threaded nozzles 57a and 57b, and tightened by the screw 54c. Then, the drive cylinder 55 is now operated to extend, and the moving member 53 is rotated and disposed along the trace G to a predetermined position on the calender roll 20 side.

Through the above-described operations, the scratched and scratched roll 30 can be replaced easily and in a short time.

Although the exchanging device for the thread/throat roll 30 in the above embodiment has been described, it is possible to easily exchange other rolls.

The present invention includes a roll changing mechanism that removably clamps both parts 11 of the mouth to the support frame erected on both sides of the roll to carry it in and out of a predetermined position. Since the saw roll exchange cart is movably arranged and equipped with a roll clamp mechanism that clamps both end shafts of the roll at the roll exchange position of the roll exchange mechanism, it takes a lot of effort and time to exchange the rolls. This has the effect of allowing for safe and efficient replacement.

Moreover, since the structure is simple, it can be manufactured at low cost and maintenance is also easy.
