Description

[Detailed description of the invention] [Industrial application field] The present invention is a winding device for winding sheet-like or film-like products, which does not compress the product and allows smooth winding. Regarding.

[Prior Art] Sheet-like or film-like products often need to be wound up using a winding device not only when the product is completed, but also during product processing and production.
In this case, the sheet-like or film-like product is wound up by the winding roller of the winding device, but in a normal winding device, the winding roller does not compress the product and rolls the product smoothly. A receiving roller is provided correspondingly.

[Problems to be solved by the invention] However, most of the receiving rollers in conventional winding devices are of a fixed type. The pressures are different, and when the amount of product rolled up is large, the product may be compressed or cut, and when the amount of product rolled up is small, the product may sag.

[Means for Solving the Problems] The present invention is a winding device designed to solve the above problems, and includes a winding roller for winding a product, a lifting device for moving the winding roller up and down, and a winding roller. a lower rotary roller which is provided parallel to the roller and comes into contact with the product of the winding roller; a holder which rotatably supports the lower rotary roller and is movable in the radial direction of the lower rotary roller; and a switch member that operates to raise the lifting device. Further, the winding device of the present invention is configured such that the holder of the receiving roller can be supported by a spring member in order to optimize the contact pressure of the receiving roller.

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

Fig. 1 shows a front view of the embodiment, and Fig. 2 shows a side view of the embodiment. is supported by. The roller receiver holder 2 has a hook shape with a bent rear part, and the front upper part is connected to an elevating device (not shown) via two left and right joints 3, and the rear part is connected to a vertical movement via a stroke bearing. The guide bar 4 is loosely aligned. A motor, hydraulic pressure, pneumatic cylinder, etc. may be used as the lifting device, and the joint 3 has a built-in spring 3a, so that when the product is rolled up with the winding roller 1 located at the top, the rotation described later is The product S of the winding roller 1 is brought into contact with the roller surface of the roller and the pulling roller 5 with an appropriate pressure.

Reference numeral 5 denotes a pulling roller, which pulls the product S in a wrinkle-free state with an appropriate force and winds it up on the winding roller 1, and in this embodiment, it is paired with a clearing roller 6. This pulling roller 5
is in contact with the product S of the winding roller 1 at the rear of the lower part of the winding roller 1 . Reference numeral 7 denotes a lower rotating roller for winding up the product S on the winding roller 1 without any slack, and is in contact with the product S of the winding roller 1 at the front of the lower part of the winding roller 1. The pulling roller 5 and the lower rotating roller 7 are both the winding roller 1
It is placed parallel to. Reference numeral 8 denotes a holder that rotatably supports the lower rotary roller 7. A receiving metal 9 is provided in the intermediate portion of the holder 8, which is attached to a fixed plate 10 so as to be movable in the radial direction of the winding roller 1. Also, holder 8
A pressing member 12 of the limit switch 11 is located at the bottom of the
is provided in a protruding manner, and a push spring 13 is also attached. The end of the push spring 13 is located on the pull roller 5 side, and is mounted so that the pressure can be adjusted by an adjustment screw 14. Therefore, the lower rotating roller 7 is connected to the winding roller 1 via the holder 8.
The product S is brought into contact with the product S with an arbitrary pressure.

In addition, 15 is a main motor which rotates the pulling roller 5, thereby sequentially rotating the winding roller 1 and the lower rotating roller 7.

According to the winding device of the embodiment configured in this way, the product S is transferred to the winding roller 1 via the pulling roller 5.
is wound up, and as the weight and thickness of the wound product S increase, the lower rotating roller 7 moves in a direction away from the winding roller 1 against the pressure of the push spring 13. When the weight or thickness of the product S on the winding roller 1 exceeds a predetermined amount and the lower rotating roller 7 also moves by a predetermined amount, the pressing member 12 at the lower part of the holder 8
presses the limit switch 11 to operate it. When the limit switch 11 is activated, the lifting device is activated, and the roller receiving holder 2 of the winding roller 1 is raised via the joint 3, and the product S of the winding roller 1 is raised.
and the contact pressure of the lower rotating roller 7 is relaxed to an appropriate contact pressure.

Note that the winding roller may be raised in stages each time the limit switch is operated. Further, it goes without saying that a switch member other than a limit switch may be used, and a plurality of switch members may be provided to raise the winding roller in stages.

[Effects of the invention] According to the winding device of the invention configured as described above, the contact pressure of the lower rotating roller for the product wound on the winding roller can always be maintained at an appropriate pressure, and the product is compressed. The product will not sag or break.
