Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a winding device capable of unloading and unloading a small-diameter winding roll of a band-like object such as a paper web.

[Prior Art] A winding device uses a slitter to cut a wide strip of paper or other material into a desired width dimension, and then winds the material around cores arranged in a staggered manner on both sides of a winding drum. Accordingly, there is a type of winding roll that can be manufactured with a required width and diameter.

However, in recent years, with the diversification of printing technology, etc., it has become necessary to manufacture winding rolls with a wide range of diameters.
A winding device having a structure as shown in the figure has been proposed.

That is, a plurality of pairs of carts 4 movable along rails 3 extending in the axial direction of the winding drum 1 are provided on both sides of the support portion 2 of the winding drum 1, and a base frame 5 is attached to each cart 4. On the base frame 5, a support frame 6 with high rigidity extending horizontally toward the side opposite to the winding drum 1 is pivotably supported around a pin 7 extending parallel to the rail 3, and is connected to the trolley 4 and supported. A cylinder 8 is interposed between the frames 6 so that the downward tilting of the support frame 6 can be driven;
A winding roll holder 10 is provided on the upper part of the support frame 6 with a chuck 9 for supporting the core and capable of moving toward and away from the winding drum 1, and a web of paper cut to a desired width by a slitter (not shown) is installed. Paper is loaded onto cores supported by chucks 9 of winding roll holders 10 provided on support frames 6 of each pair of carts 4 which are arranged in a staggered manner on both sides of the winding drum 1 according to the width dimension of the paper web. As the paper web becomes thicker, the paper web is wound up while separating the winding roll holder 10 from the winding drum 1, and when the desired winding diameters of the rolls a and b are obtained, When the roll holder 10 is moved to the tip of the support frame 6 and the cylinder 8 is contracted to tilt the support frame 6 downward, the wound rolls a and b are automatically unloaded onto the table 11. Therefore, even a large diameter and heavy roll a can be safely and reliably unloaded.

12 is a motor provided on the truck 4 for driving a gear 14 meshing with the rack 13; 15 is a roller of the truck 4; and 16 is a stopper for the roll holder 10.

[Problem to be solved by the invention] However, in the above-mentioned winding device, the support frame 6 must have a thick dimension d to increase its rigidity so that it can hold the winding roll a which has a large diameter and a large weight. Therefore, when the support frame 6 is tilted downward and touches the table 11, the distance e from the center of the core supported by the chuck 9 located at the tip of the support frame 6 to the top surface of the table 11 is
Smaller diameter winding roll c (hereinafter referred to as small diameter winding roll)
could not be automatically unloaded.

Therefore, when unloading the small diameter roll c, a worker brings in a stand, unloads the small diameter roll c onto the stand, and then unloads the small diameter roll c from the stand onto the table 11. I had to do it, and it was inefficient.

In view of the above-mentioned circumstances, the present invention aims to enable automatic unloading of both large-diameter rolls and small-diameter rolls.

[Means for Solving the Problems] The present invention includes at least a pair of support frames arranged on at least one side of the winding drum so as to be tiltable downward until the opposite side of the winding drum touches the table. A winding roll holder that can approach and move away from the winding drum is attached to the support frame, and a pit that can be opened and closed by a slide table is provided at the unloading position near the support frame grounding position of the table, and a pit that can be opened and closed by a slide table is provided in the pit. The present invention relates to a winding device characterized in that a small-diameter roll holder whose drum side can be tilted downward is provided so as to be movable up and down.

[Function] By opening the pit with the slide table, raising the small-diameter roll holder, and tilting the support frame downward, the small-diameter roll is unloaded from the roll holder of the support frame onto the small-diameter roll holder. After the small diameter roll holder is lowered to the same height as the top surface of the slide table, the side of the small diameter roll holder opposite to the winding drum is tilted downward, and the small diameter roll is unloaded onto the slide table and the table.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 shows one embodiment of the present invention, and the parts in the figure with the same reference numerals as in FIG. 2 represent the same parts.

A pit 17 is provided at the unloading position near the grounding position of the support frame 6 of the table 11.
A slide groove 18 extending perpendicularly to the axis of the winding drum 1 is provided near the opening of the pit 17 of 1, and a guide 19 slidably fitted into the slide groove 18 is provided so that the upper surface of the pit 17 can be opened and closed. A slide table 20 is provided, and a cylinder 21 is interposed between the table 11 and the slide table 20 so that the slide table 20 can be driven to open and close.

An elevating table 22 extending in the width direction of the winding drum 1 is provided in the pit 17 so as to be driven up and down by a cylinder 23, and an arm 24 extending in the width direction of the winding drum 1 is raised on the upper side of the elevating table 22 on the side opposite to the winding drum 1. The arm 24 is pivotally attached with a pin so that it can be tilted freely, and a cylinder 25 is interposed between the lifting platform 22 and the arm 24 to drive the arm 24 up and down.

A rail 26 extending in the width direction of the winding drum 1 is laid on the upper part of the lifting platform 22, and a plurality of pairs of small diameter roll holders 28 are movably arranged on the rail 26 via conventionally known linear bearings 27. . The small diameter roll holder 28 has a side opposite to the winding drum 1 that can be raised and lowered by an arm 24 of the lifting table 22.

Note that 29 is a bar attached along the upper surface of the arm 24.

Winding and unloading of the large-diameter roll is performed automatically in the same manner as shown in FIG.

When unloading the small diameter roll c, move the roll holder 10 that holds the small diameter roll c to the top of the unloading position at the tip of the support frame 6, and at the same time contract the cylinder 21 and move the slide table 20. The pit 17 is opened, the pair of small-diameter roll holders 28 in the unloading position are moved to the lower part of the small-diameter roll c, and the cylinder 23 is extended, thereby raising and lowering the lifting table 22, that is, the small-diameter roll holders 28. When the cylinder 8 is moved up as shown on the left side in FIG. 1 and the support frame 6 is tilted downward as shown by the imaginary line in FIG. The cylinder 23 is further contracted to lower the small diameter roll holder 28 to the same height as the top surface of the slide table 20, the cylinder 25 is contracted, and the arm 24 is unloaded.
When the small-diameter roll holder 28 is tilted down (tilted downward), the small-diameter roll c is moved to the slide table 20.
and is automatically displayed on the table 11.

After unloading the small diameter roll c, as shown on the right side of FIG.
Close 7.

It should be noted that the winding device of the present invention is not limited to the above-described embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.

[Effects of the invention] As explained above, according to the winding device of the present invention, a pit that can be opened and closed by a slide table is provided at the unloading position near the support frame grounding position of the table, and the unwinding is carried out in the pit. Since the small-diameter roll pedestal whose take-up drum side can be tilted downward is provided so as to be movable up and down, an excellent effect can be achieved in that the large-diameter roll and the small-diameter roll can be automatically unloaded onto the table.
