Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an apparatus and method for manufacturing a coreless paper roll of coreless paper without a paper tube as a core on the inner periphery.

<Conventional technology> Conventionally, as a production equipment for coreless paper rolls,
Various methods have been proposed, such as those shown in Japanese Patent No. 129440. According to this, initially a configuration was adopted in which paper was wound around a winding shaft and the rolled paper of a predetermined thickness was pushed out from the winding shaft, making the paper winding and punching operations more efficient. In order to mass produce roll paper, the roll shaft is placed on a conveyor and intermittently fed to a paper winding device. When the roll paper has been wound to a predetermined thickness, the roll paper integrated with the winding shaft is transferred to the punching position by the supporting device of the conveyor, and the pressing member of the punching device attached to the conveyor chain moves the roll paper to the punching position. , the roll paper is pushed out from the winding shaft, one end of which is fixed, and the remaining winding shaft is transported to a position for winding the roll paper by means of a support on the conveyor.

<Problems to be Solved by the Invention> However, in such a conventional coreless paper roll manufacturing apparatus, both the conveyance of the roll shaft to the winding position and the punching operation by the pressing member of the punching device are performed. Since it uses an endless conveyor, the structure is complicated and large, and it is necessary to use an auxiliary cylinder operated by an air cylinder to move the rolled paper to the punching position after winding. , there were problems such as the configuration and operation becoming complicated.

This invention has been made in view of such conventional problems, and the movement of the single roll shaft to the paper winding device and the punching operation by the punching member of the punching device are performed without relying on the rotational movement of the conveyor. In addition to making it possible to perform it in a relatively small occupied space,
It is an object of the present invention to provide a manufacturing apparatus and method for manufacturing a coreless paper roll, in which the roll paper can be guided to a punching position by simple planting.

〈Means for solving problems〉 A manufacturing apparatus for a coreless paper roll according to the present invention is:

The winding shaft is supported while rotating on the drive roller.

As the drive roller rotates, the paper, one end of which is fixed, is wound around the winding shaft, and the paper roll being wound is pressed from above by the pressure roller.

The roll body that has been wrapped is pushed and rolled onto the support member at the punching position using a push cylinder, and the paper continuous to the roll body on the support member is cut by a cutting machine. One end of the roll body on which the paper is wound is locked by a locking member, and the roll body is pushed out from the winding shaft while the supporting member is moved by a punching member, and the winding shaft after this punching is pushed out. It is configured to be sandwiched between the winding shaft transfer members and transferred onto the drive roller.

Further, the method for manufacturing a coreless paper roll according to the present invention includes the steps of: attaching one end of the paper from the original roll to a winding shaft; and then winding the paper on a drive roller by rotation of the drive roller; After this winding is completed, the rolled roll body is pushed out of the drive roller by a push cylinder and rotatably supported on a support member, and in this supported state, the paper continuous with the roll body is cut by a cutting machine. After this cutting, one end of the winding shaft is locked so that it cannot move in the axial direction, and then the roll body is pushed out from the winding shaft by a punching member while moving the supporting member, and the punched out winding shaft is removed. is transferred onto the drive roller by a winding shaft transfer member.

Function> The punching device of the present invention moves the support member in the punching position forward in the axial direction so as to push the roll body against the winding shaft which is locked at one end. After each punching operation, it returns to its original position and prepares for the first punching operation. Further, after the punching is completed, the winding shaft remaining on the support member is grabbed by the winding shaft transporting member and operated to be transferred onto the drive roller on the paper winding side. As a result, there is no need to use a conventional large conveyor for punching and transporting the rolls, the installation space for each of these components can be reduced, and the entire coreless paper roll manufacturing equipment can be downsized. It works like this.

<Embodiment of the Invention> An embodiment of the invention will be specifically described below with reference to the drawings. FIG. 1 shows an apparatus for producing a coreless paper roll according to the present invention, which includes a paper winding section A, a punching section B that punches out the paper roll, a paper zero cut section C, and a paper roll cutting section C. It consists of a winding shaft transfer section that transports the winding shaft of the punching section B to the paper winding section A.

First, the winding section A consists of a pair of drive rollers (2) and (3) that support the winding shaft (1) while rotating, and a paper roll (4) wound around the winding shaft (1). A press roller (5) that lightly attaches from above to the roll body (4), a cylinder (6) that presses the press roller (5) against the roll body (4), and a paper (not shown) that is delivered from a 1M counter roll (not shown). 7
), and at the beginning of winding the paper (7) on the winding shaft (1), the end of the paper from the original roll is attached to the winding shaft (1) and one winding is carried out. It is composed of an air injection pipe (9) that injects air to enable this. Further, (10) is a pressing cylinder provided with one end facing above the driving roller (3), and the piston rod (11) end of this cylinder projects near the driving roller (3) when pushing out the roll body (4). It looks like this.

In addition, as shown in FIG.
), a punching member (15) attached to the chain (14) and reciprocating between the chain wheels (12) and (13), and a fork-shaped punching member (15) attached to the punching member (15). bearing members (16) and these bearing members (1
6) A pair of support rollers (17) that rotatably support the roll body on the winding shaft (1) supported above on the lower peripheral surface thereof.
and a locking member (18) that locks one end of the winding shaft (1) supported on the support member (16) so that it cannot move in the axial direction. Side plate (19)
It is provided on one side of the

In addition, the chain wheel (13) has a pulley (13a
) Rotation is transmitted from the motor (13b) through the motor (13b), and this is controlled to rotate in forward and reverse directions at a predetermined speed.

Furthermore, the cutting part C of the paper is the winding part A and the punching part B of the paper.
a cylinder (21) having a piston rod with a cutter blade (20) attached to the tip; A pair of support rods (22)
A glued thread (
23), this glue pot (24) contains a glue box (24) containing liquid glue in which the thread (23) is dipped, and this glue pot (24).
), the gluing device consists of a pot operating device (25) that is held out to a position where the thread is dipped and then withdrawn at a certain timing.

Furthermore, the first-volume shaft transfer section includes a cylinder (31) that is swingably provided around a support shaft (30), and a grip that is attached to the end of a piston rod that moves in and out of this cylinder (31). It consists of a member (32) and another cylinder (33) that swings the cylinder (31) by moving the piston rod in and out.

Next, we will discuss the operation. Now, one end of the paper (7) from the original roll is guided onto the two drive rollers (2), (3) via the guide roller (8), and then.

First, the winding shaft (1) is placed on the drive rollers (2) and (3) via this paper (7). In this state, compressed air is injected from the injection pipe (9) to Upon receiving the jet of air, the above-mentioned end of the paper (7) is rolled up onto the roll @ (1), and one end of the rolled up paper (7) is properly pressed by the pressure roller (5) lowered by the cylinder (6). After contacting with contact pressure, the drive rollers (2) and (3) are driven by a motor at a predetermined speed to wind the paper (7) onto the winding shaft (1). In this way, when the roll body (4) of the paper (7) reaches a predetermined thickness, the pressure roller (5)
is moved upward by the contraction operation of the piston rod of the cylinder (6), and then the roll body (4) is pushed out to the left guide passage R by the end of the piston rod (11) of the cylinder (10). Therefore, the roll body (4) rolls on its guide path R, and the winding shaft (1
) is received so that the end thereof is supported. At this time, the roll body (4) has its outer periphery in contact with the pair of support rollers (17) so that it can rotate together with these support rollers (17).

In this state, the cylinder (21) operates to lower the cutter blade (20) between the winding section A and the punching section B, and the roll body (4) and the original fabric roll ( (not shown) to cut the continuous paper (7). At this time, the glue thread (23) is attached together with the cutter blade (20).
The thread (23) is glued onto the paper (7) on the roll body (4) side a little distance from the cut part. Also, this paper (7)
After cutting, the cutter blade (20) retracts upward together with the glue thread (23), and during this retraction period, the glue thread (23) is inserted into the glue box (24) pushed out by the cylinder (25). 23) is soaked and glue is attached to it. When the cutting of the paper (7) is completed, the support roller (17) rotates to cut the paper (7).
The remainder of the paper (7) is also rolled up onto the roll body (4), and at this time, the end of the paper (7) is stuck to the roll body (4) at the linear gluing section. In this case, since the gluing section and the cutting section are spaced a certain distance, it becomes easy to unravel the paper at the gluing section during use.

Next, the roll body (4) with the winding shaft (1) on the support member (16) as described above is assembled with the chain wheel (12), ( 13)
While placed on the punching member (15) attached to the upper chain (14), it moves axially in the direction of arrow P in FIG. At this time, one end of volume till (1) (the right end head)
is locked by a locking member (18) provided on the side wall (19), and movement of this winding shaft (1) in the direction of arrow P is restricted. Therefore, the supporting member (16) is attached to the roll body (4).
The end face of the roll body (4) is pressed in the direction of arrow P, and the roll body (4) is pushed out from the winding shaft (1). In addition, the roll body (4) to be punched out by punching is
5), it is pushed out from the winding shaft (1).

For this reason, the tip of the punched roll body (4).

Finally, a pair of conveyors (29a) located outside the side wall
(29b) and carried out to the outside. thus,
When all the roll bodies (4) are carried out to the outside of the side wall.

The winding shaft (1) spans over the support member (16) and the locking member (18), and the piston rod (34) of the first cylinder (31) extends and descends, and the gripping member (32)
) after gripping the winding shaft (1), the motor (13)
As a result of the reverse rotation, the punching member (15) returns along the forward path, reaches the rightmost end, and prepares for the supporting operation of the next winding shaft (1).

By the way, even after the roll body (4) is carried out, only the winding shaft (1) remains between the locking member (18) and the member (16).
The cylinders (33), (31) operate to extend the piston rod of the gripping member (32) to grip its remaining winding shaft (1), and further contract or extend the piston rod to grip its remaining winding shaft (1). the drive roller (2) of the winding section A.
), (3) facing above, and then gripping member (32)
Release the gripping action of this drive roller (2), (
3) Place the winding shaft on top and wait for the next roll body winding operation.

In this way, the winding, cutting, punching of the paper (7), and the transfer of the roll shaft (1) are carried out continuously and repeatedly, and a coreless paper roll is manufactured.

<Effects of the Invention> As described above, according to the present invention, a coreless paper roll manufacturing apparatus is provided with a winding section A and a punching section B that do not use an endless belt conveyor, and cutting and gluing of paper. Since it is composed of a cutting section C that is carried out at a separate location and a single-volume shaft transfer section, the overall configuration of the bookbinding can be simplified and downsized, and the reliability of the operation can be increased. It will be done. Furthermore, according to this method of manufacturing coreless paper rolls, complicated auxiliary members such as conventional auxiliary guides and the above-mentioned belt conveyor are omitted, simplifying operations such as paper feeding and processes. , it is possible to speed up the transfer and processing of the roll body and the winding shaft, and effects such as an improvement in the manufacturing speed of the roll body can be obtained.
