Description

TECHNICAL FIELD The present invention relates to a roll stacker roll for winding and stocking printed matter on a peripheral surface of a roll with a holding tape. This roll for a roll stacker is used for temporary storage of printed matter and feeding for feeding to a collator between a printing machine and a bookbinding machine.

(Prior Art) Conventionally, this type of roll for a stacker rolls a printed matter, for example, a signature, which is supplied by a plurality of holding tapes which are separated from each other in the axial direction of the roll and whose one end is fixed to the circumferential surface of the roll. I kept it wrapped around.

(Problems to be Solved by the Invention) However, if the printed matter has a partial difference in thickness, specifically, a postcard is stuck on a signature or the like and a part of the postcard is thickened, the postcard sticking side is unevenly thickened. Then, the signature wound between the winding layers of the roll may slip and the roll may collapse. Therefore, an object of the present invention is to provide a roll stacker roll in which roll collapse does not occur even when a printed material has uneven thickness.

(Means for Solving the Problem) In order to achieve this object, printed materials that are flatly arranged in a certain posture and continuously conveyed are placed on a plurality of tapes extending in parallel, and the plurality of tapes are wound around a roll. A roll stacker roll wound around a surface to hold a large number of printed materials between the tape and the roll peripheral surface, the thickness of a portion of the plurality of tapes located in the orthogonal direction of the tape in the printed materials. The feature is that a difference in wall thickness is provided according to the difference in.

According to the roll stacker roll of the present invention, in the case where there is a difference in the thickness of a portion of the plurality of tapes which are supported so as to be wound around the roll peripheral surface in the direction orthogonal to the tape, the difference in the thickness of the printed matter By providing a difference in the thickness of the tape in accordance with the above, even if a large number of printed matter is wound around the roll circumferential surface by successively superimposing the printed matter on the front and back, it is possible to prevent the difference in the thickness of the printed matter from accumulating.
The printed matter on the peripheral surface of the roll is wound around the roll with a substantially uniform radius in the axial direction.

(Example) Next, this invention is demonstrated based on drawing.

1 to 4 show an embodiment of the present invention. In the figure,
Reference numeral 1 denotes a frame forming a roll stacker, which has a U-shape that opens upward. The shaft 5 of the roll 3 is supported on the upper portion of the frame 1 so that the roll 3 is rotatable.
Although not limited to the resin tape on both sides of the rotor 3 on the shaft 5, here, a holding tape made of polyester or the like is used.
Retaining tape supply reels 9a and 9b are provided, with one end of each of the retaining tapes 7a and 7b fixed and winding of the retaining tapes 7a and 7b by unillustrated winding biasing means.

The holding tapes 7a and 7b are pulled out from the holding tape supply reels 9a and 9b as shown in FIGS.
After passing through the rollers 1a, 11b, the second rollers 13a, 13b, and the third rollers 15a, 15b, as shown in FIG. 3, they are separated from each other in the direction of the axis 5 of the roll 3 and fixed at the other end.

A dovetail groove 3a extending in the axis 5 direction is formed on the outer peripheral surface of the roll 3, and a trapezoidal piece 4 is movably inserted in the dovetail groove 3a.

The movement of this piece 4 is restricted by being biased to the outside of the roll 3 in the radial direction by a built-in spring, or by a known screw mechanism (not shown). Each end of the holding tapes 7a and 7b is fixed to the piece 4 by sandwiching or screws.

Further, below the roll 3, a belt conveyer 17 is installed in the frame 1 so as to be swingable or movable, and the printed matter 19 is rolled up from the state where the roll 3 is close to the outer circumference, and the outer diameter increases. It is always close to the outer circumference.

The printed matter 19 is, for example, a folded signature that is folded in two, and a postcard 19a, which is smaller and thicker than other things, is folded in, which is an example of uneven thickness. In such a case, the A side of the printed matter 19 (the side where the postcard 19a is pasted) and the B side
There is a difference in thickness of two postcards 19a from the side, and one of them is sequentially superposed on the belt conveyor 17 as shown in FIG. 2 and wound around the roll 3 with the holding tapes 7a and 7b. The holding tapes 7a and 7b are provided with a difference corresponding to the difference thickness in order to remove them. That is, the B-side holding tape 7b is the A-side holding tape.
The thickness of 7a is obtained by adding and correcting the difference thickness.

Although two holding tapes have been described above, the present invention is not limited to this, and a roll stacker that cooperates with at least two holding tapes to sequentially wind and stock printed matter around a roll has been described. When the printed material of the holding tape has a partial thickness difference at the winding position of the printed material, the thin holding tape has a thickness that is added and corrected by the difference thickness from the thick holding tape.

 The use of this roll stacker will be explained.

The printed matter 19 is a signature folded as shown in FIG.
When the postcard 19a is stuck to this part and uneven thickness occurs, the holding tape 7a wound around the position of the postcard 19a on the A side is thin, and the holding tape 7a wound around the position of the B side is pressure-differential. Select the one with the added thickness and correction, and set the holding tape supply reels 9a, 9b respectively, and the rollers 11a, 11b, 13a, 1
3b, 15a, 15b, and the position of the piece 4 shown in FIG. 3 is also set and fixed at the winding position of the printed matter 19.

In this state, when the printed matter 19 is sequentially supplied onto the belt conveyor 17, the outer periphery of the roll 3 or the printed matter 19 wound around the roll 3 and the holding tape 7 at the tip position of the belt conveyor 17.
It is sent to the pharynx formed between a and 7b and holding tape 7a, 7
The wound layer is wound while being tightened at b to form a wound layer of the printed matter 19.

At this time, although the printed matter 19 has uneven thickness, the holding tapes 7a, 7b
Therefore, the sum of the thickness of the holding tape 7a and the thickness of the printed material 19 on the A side of the holding tape 7a is the difference between the thickness of the holding tape 7b and the B side of the printed material 19 on which the tape passes. Since the sum of the thickness and the thickness is always equal, the outer circumference is always parallel to the axis 5 even if the printed material is rolled up and the outer circumference is large, and the signature slips and the roll collapses. There is no such thing.

(Effects of the Invention) As described above, according to the present invention, since the holding tape is set by providing the thickness difference corresponding to the uneven thickness of the printed matter, even if a lot of printed matter is wound around the outer circumference of the roll. The printed matter does not slip, and the roll collapse does not occur.
