When it is detected that the broke is formed into a roll shape, the lower stage take-up rollers 27, 28 are opened, thereby, automatically the rolling up and discharge of broke.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a paper winding device that is applied to roll and discharge laminated waste paper cut in an automatic paper winding device.

[Conventional technology]

As shown in FIGS. 5 and 6, the waste paper 3 of the web cut by the cutter 2 of the automatic web trimming device 1 is fed onto the table 5 by the guide roller 4 and the web drive motor 13.

The paper is discharged into a waste paper box 9 by a tension roller 6 at the lower end of the table 5 and a pressure roller 8 pressed against the tension roller 6 by an air cylinder 7. In addition, if the pair of tension rollers 6 and presser rollers 8 are located low, a pit for the waste paper box 9 must be provided at a location lower than the floor, so a paper discharge conveyor 10 is provided, and the pair of belts of the paper discharge conveyor 10 is ,
Between 11 and 12, the waste paper 3 is narrowed and guided upwards from an appropriate height and dropped into the waste paper box 9 as shown in Figure (b).

In any case, the cut waste paper 3 is discharged in the form of a sheet, but when the waste paper 3 is directly discharged into the waste paper box 9, as shown in Fig. 6 (at) and (b). Since the paper falls naturally due to its own weight, the paper will fold into a dumpling shape or overlap.
Or they may intertwine, resulting in a very complex shape.

It also becomes bulky. In addition, when the waste paper 3 is ejected using the paper ejection conveyor 10, when the waste paper 3 is caught between a pair of bells) 11 and 12.

The paper is delivered to the waste paper box 9' in a crumpled or, in some cases, torn state.

[Problem that the invention seeks to solve]

Such conventional devices have the following problems.

(1) The wrinkles, distortions, and curls that occur when the waste paper cut by the automatic roll paper finishing device is discharged through the tension roller into the waste paper box are discharged without being corrected.

This is a disadvantage because waste paper with these problems is treated as waste paper and can only be taken back at a low price. (
(2) Disposing of the stacked sheets of waste paper is bulky and difficult to dispose of, and the waste paper transport equipment is large, and since the waste paper is in sheet form, the processing itself is difficult. Difficult and a barrier to automation.

(3) In the case of (1) above, if the sheet-like waste paper is rolled up into a roll, it can be reused as a product, so it can be sold at a good price.

Labor costs are high because it is manual work.

[Means for solving problems]

In order to solve these problems, the present invention is a device for discharging waste paper from a roll of paper cut by an automatic winding machine, in which a plurality of winding rollers are arranged in an arc, The take-up rollers are rotated in the same direction, and each take-up roller is made up of a plurality of disks, and the disks are arranged in a mutually interlocking manner so that the nine disks do not come into contact with each other. To provide a paper winding device characterized by winding a sheet of waste paper guided by a roller and a presser roller into a roll.

[For production]

Since the present invention has such a configuration, a plurality of take-up rollers arranged in a 9-circular shape rotate in the same direction and at the same speed, so the waste paper is easily rolled, and the circular shape of each take-up roller is rotated in the same direction and at the same speed. Since the plates are inserted into each other, the waste paper does not fly out to the outside, and the lower take-up roller is opened when the waste paper is detected to form a roll, making it into a roll.

Automation of discharge becomes possible.

〔Example〕

As shown in FIGS. 1(a) and 1(b), the waste paper 3 cut by the cutter 2 of the 9-roll paper automatic tailoring device 1 passes through the table 5, forms a pair with the tension roller 6, and is transferred to the air cylinder 7. The process up to the presser roller 8 that applies nip pressure is the same as that described in the prior art section.

The waste paper 3 fed out by a pair of rollers 6.8 is guided by a pair of guides 21.21'.

Take-up roller 26 and presser roller 25 (at this time.

The pressing roller 25 is in a disengaged state with respect to the winding roller 26, that is, in the position shown by the broken line. ) to get into the gap between By this time, the tension roller 6 and each of the winding roller groups 26 to 31 have been rotationally driven by the motor 35 in the direction of the arrow (as shown in FIG. 2). Next, when it is detected that the waste paper 3 has passed the take-up roller 26, the presser roller 25 is pressed against the take-up roller 26 to forcibly feed the waste paper 3. Since the take-up roller groups 26 to 31 rotate in the same direction and at the same speed, the waste paper 3 that has been fed is transferred to the take-up roller group 26.
31, and is neatly wound into a roll as shown at 3'. Take-up rollers 27 and 2 are used to take out the completely wound waste paper 3 from the discharge paper take-up device 36, which is composed of take-up roller groups 26 to 31, etc.
8 in the direction of the arrow with an air cylinder (not shown) to cause the rolled waste paper 3' to fall downward. At this time, each winding roller group 26 to 31
is rotating. Each winding weir roller group 26 to 31 is the second
As shown in the figure, it consists of multiple discs, which are arranged at regular intervals, placed side by side so as not to touch each other, and stacked on top of each other. Therefore, the waste paper 3 does not escape from between the winding roller groups 26 to 31 to the outside. Each of the winding roller groups 26 to 31 is equipped with a disc made of a material that has a high coefficient of friction with the paper, or a disc 9 whose surface has been treated to increase the coefficient of friction, such as a rubber disc or a knurled steel disc. etc. are used so that the coefficient of friction with the waste paper 3 becomes large.

It is easy to wind and comb. However, the surface of the disk of the 9-roll weighted roller 31 is made smooth and made of a material that reduces the coefficient of friction with the waste paper 3, thereby preventing the rolled waste paper 3' from being discharged to the outside. . The air blow pipe 23 provided below the guide 21 takes up the waste paper 3 at a winding roller group 26.
~31 is used as an auxiliary means to make it easier to enter. Therefore, the air blow tube 23 is attached to the guide 23.
There is a cutout hole in the part corresponding to the part where the air is blown. Also, the air blow tube 24 presses the waste paper 3 at the initial stage of winding against the winding rollers 26, 27, and 28 to facilitate winding and winding*! This serves to push back the waste paper 3' that is about to be discharged along the roller 31.

When the waste paper 3 is wound several times, the presser roller 25 is in the unloaded state (the position indicated by the broken line), and then the presser roller 8 moves in the direction of the arrow and comes into contact with the tension roller 6, and the paper winding device 36 The waste paper 3 is fed in and the tension of the waste paper 3 fed out onto the table 5 is kept constant. The guide 22 serves as a guide when several sheets of waste paper 3 that have fallen all at once on the table 5 are lifted up.

The rotation speed of the winding roller groups 26 to 31 is set slightly faster than the speed of the tension roller 6.

This prevents sagging during the process. Winding roller 27.28
The method for discharging the roll-shaped waste paper 3 that has fallen from the gap is carried out by the waste paper box 9 as described in the prior art section or by the paper discharge conveyor 32 as shown in FIG.

The paper discharge conveyor 32 is different in that nine paper receiving arms 33 for receiving the roll-shaped waste paper 3' are attached to a rotating chain 34 at equal intervals.

Therefore, the roll-shaped waste paper 3' discharged from the paper winding device 36 is held by the paper receiving arm 33 and conveyed to the waste paper box 9'.
will be put into the

〔Effect of the invention〕

According to the paper winding device of the present invention described above.

The following remarkable effects can be obtained.

(1) The winding up of waste paper is completely automated (unmanned), resulting in labor savings.

(2) Since the waste paper is neatly rolled up, the product value is high, and the company can take it back at a high price, which improves profits.

(3) Since the waste paper is discharged in the form of a roll, complete automation of the waste paper discharge process can be achieved by installing an appropriate paper discharge conveyor device.

(4) Since the main paper winding device is designed to be compact, the entire double-roll automatic paper finishing device can be made smaller, and when a paper discharge conveyor is installed, the paper discharge conveyor for sheet-shaped waste paper is more compact than roll-shaped waste paper. Since the paper ejection conveyor is smaller, the overall installation space is saved.
