Description

[Detailed description of the invention] (Field of industrial application) This invention is applied to roll products wound by a slitter winder, in which the sheet end face and the core tube end face are not flush but are shifted. The present invention relates to a device for correcting positional deviation.

(Prior art) A plurality of core tubes 15 are formed by vertically cutting a plurality of rows of narrow sheet-like materials 14 from a wide original fabric S and having the same length as the narrow sheet materials 14 and fitted in vertical rows onto a single core shaft. A slitter winder (see Fig. 4), which winds each film to form a roll product 13, is often used as a manufacturing device for wrap film products for packaging. It is difficult to accurately align the slit position of the wide original fabric and the end position of the heart tube fitted on the core shaft.
In addition, since there is a problem in that a complicated device is required to make this alignment accurate, generally the heart tube 15, for example, a paper tube, protrudes slightly on one side, as shown in FIG. The reality is that they are being sent to the market as products.

(Problem that the invention attempts to solve) Recently, there have been demands from customers to improve products with uneven end faces as they lose their commercial value. However, manual hammering is not suitable for mass production due to its low performance and the risk of damaging the edges of the sheet material.
Apart from this, some methods have also been used to cut off the protruding portions, but this also has the problem of damaging the sheet-like material.

In response to these circumstances, the present invention has been developed to provide a device that is efficient for mass production and capable of end face correction with uniform high quality. The present invention is characterized by a structure in which the misalignment of the heart tube can be easily corrected by a hammering means without damaging the end surface of the object,
The purpose of the present invention is to inexpensively and quickly manufacture beautiful roll products with neatly arranged end faces, thereby playing a role in rationalization.

(Means for Solving the Problems) However, as is clear from the drawings showing the embodiments, the present invention provides a method for attaching a narrow sheet-like material 14 to a heart tube of equal width.
A product receiver is provided with a receiving tray 2 capable of receiving a rolled product 13 formed by winding the rolled product 13 on a central portion thereof in an axially horizontal manner so that the rolled product 13' mounted on the receiving tray 2 can be moved in the axial direction. a mechanism 1, and a tray provided on one side of the product receiving mechanism 1 in the movement direction of the tray 2,
A pressure-receiving fixing plate 3 fixed to the end face of the loaded roll product 13' with a vertical surface facing the product axis extension line, and a receiving plate 2 of the product receiving mechanism 1.
a backing plate 4 provided on the other side of the movement direction, having a vertical surface facing the pressure receiving fixing plate 3 along the product axis extension line, and capable of horizontal movement in the product axis extension line; an actuator 5 for horizontally moving the backing plate 4 and the pressure-receiving fixing plate 3 to a predetermined position where the loaded roll product 13' can be held;
Then, a hitting block 6 is provided coaxially and horizontally movably on the side opposite to the pressure-receiving fixed plate 3 with respect to the backing plate 4, and this hitting block 6 is moved toward the backing plate 4 to cause a collision. The urging mechanism 7 constitutes an end surface correction device for roll products.

(Function) When the roll product 13 is mounted on the receiving tray 2, the actuator 5 is operated to horizontally move the backing plate 4 toward the pressure-receiving fixed plate 3, and both plates 3,
4 to pinch the rolled product 13, and then the actuator 5 is released to allow the cover plate 4 to move freely.

Next, when the biasing mechanism 7 is activated to cause the striking block 6 to collide with the backing plate 4, the impact causes the backing plate 4 to move in the direction of increasing the clamping force generated between it and the pressure-receiving fixed plate 3. In order to do so, both plates 3 and 4
act on the end surface of the roll product 13 in opposition to each other, and as a result, no matter which side the heart tube 15 protrudes, the positional deviation between it and the sheet-like material 14 is corrected by the acting force. be done.

In this case, the output of the biasing mechanism 7 is set to an appropriate value so that the impact force of the striking block 6 is applied to the sheet-like object 14.
By preventing the material from being compressed and deformed, it is possible to obtain a rolled product 13 with beautifully arranged end surfaces.

(Example) Hereinafter, an example of the present invention will be described based on the accompanying drawings.

1 to 3 are schematic structural diagrams of an embodiment of the present invention, and this device includes a product receiving mechanism 1, a pressure receiving fixing plate 3, a backing plate 4, an actuator 5, a striking block 6, and a biasing mechanism 7. The main components are:

The product receiving mechanism 1 includes a base (not shown) having a horizontally extended rail 8 on its upper surface, a sliding body 9 that slidably engages with the rail 8 and moves in the horizontal direction, and the sliding body 9 It is provided on one side where the pressure-receiving fixing plate 3 is located, that is, extending between the sliding body 9 and the rail 8 in order to elastically restrict movement to the left in FIG. buffer spring 1
0, consists of each member of the saucer 2 fixed to the sliding body 9, and the saucer 2 is obtained by longitudinally dividing a cylinder whose axial length is shorter than the width of the roll product 13, that is, the axial length. It has a substantially semicircular gutter shape, and is fixed to the sliding body 9 so that its axis is parallel to the rail 8.

The product receiving mechanism 1 configured in this way is capable of handling roll products 1.
3 is received by the saucer 2 at its central part,
In this case, the loaded roll product 13' is
The receiver tray 2 is received in a state where it protrudes in the axial direction (left and right direction), and of course it is mounted while keeping the axis horizontal, and when the receiver tray 2 is moved horizontally guided by the rail 8, it is mounted. It begins to move in the axial direction of the rolled product 13'.

The pressure-receiving fixing plate 3 is a thick-walled plate made of a heavy rigid body, and is connected to the receiving plate 2 of the product receiving mechanism 1.
The fixing plate 3 is provided on one side in the direction of movement, and this fixing plate 3 has a vertical surface that faces the end face of the loaded roll product 13' along an extension line of the product axis. It is fixed so that it does not move by sufficiently resisting the impact force received from it.

The abutting plate 4 is, for example, a plate body formed of the same material and approximately the same shape as the pressure-receiving fixing plate 3, and is a sliding plate that is slidably engaged with a rail 11 provided parallel to the rail 8. It is fixed to the base 12 and provided on the other side of the product receiving mechanism 1 in the direction in which the receiving tray 2 moves.

This backing plate 4 has a vertical surface facing the pressure-receiving fixing plate 3 at the product axis extension line of the loaded roll product 13', and is fixed to the sliding base 12 so as to be horizontally movable in the direction of the product axis extension line. There is.

On the other hand, the actuator 5 is a drive device for horizontally moving the backing plate 4, and is, for example, a pneumatic cylinder, which fixes the cylinder body in parallel with the axis of the rail 11 and slides the tip of the rod. It is connected to a movable base 12 so that the caul plate 4 can be moved between a position in which it abuts the end face of the loaded product roll 13' and a suitable position away from the end face.

It should be noted that an escape allowance is provided at the connecting portion between the rod tip of the actuator 5 and the sliding base 12, or the connecting portion between the sliding base 12 and the backing plate 4, to cushion the impact from the hitting block 6, which will be described later. It is preferable to provide a structure having the following.

Next, the hitting block 6 is made of, for example, a hard alloy resin and is formed into a block having a size and strength sufficient to apply the required impact to the backing plate 4,
It is provided on the side opposite to the pressure-receiving fixing plate 3 with respect to the backing plate 4 so as to be movable coaxially and horizontally. In the illustrated example, the striking block 6 is horizontally movable by being engaged with the tip of a rod of a pneumatic cylinder 7 which is disposed at a predetermined position with its axis horizontal. In this case, the pneumatic cylinder 7 constitutes an air hammer type biasing mechanism 7.

In other words, by supplying pressurized air at a predetermined pressure to the pressure chamber on the forward side of the rod for a short period of time,
The hitting block 6 instantaneously moves at high speed toward the backing plate 4 and collides with it, and is also operated to move backward due to the reaction force, thus moving the backing plate 4 against the pressure receiving fixed plate 3.
It can be moved elastically to the side.

The biasing mechanism 7 may be of an air hammer type using an air spring, or may be a spring type using the energy stored in a coil spring.

The apparatus having the above-mentioned configuration moves the rod after the pneumatic cylinder forward from the state shown in FIG. 1 in which the rolled product 13 is mounted on the tray 2 so that the central portion is supported, and the loaded rolled product 13' is moved forward. Abutment plate 4 is applied to the end surface, and further the receiving tray 2 and the loaded roll product 13' are pushed forward until the opposite end surface of the product 13' comes into contact with the pressure receiving fixing plate 3, and the pneumatic cylinder 5 is moved. Stops forward movement.

Incidentally, this stopping can be easily automated by a signal from a limit switch, and the operating state of the device at this time is as shown in FIG.

Next, when pressurized air is fed into the pressurizing chamber side of the pneumatic cylinder 7 for a short period of time, the cylinder 7
The striking block 6, which is attached to the end of the rod, moves forward vigorously and collides with the backing plate 4.

As a result, collision energy is generated, but this energy is evenly distributed and propagated to the vertical plane of the backing plate 4, and the corresponding plate 4 is elastically moved by the loaded roll product 1.
Press evenly against the end face of 3'.

In this way, the loaded roll product 13' is clamped by the pressure-receiving fixing plate 3 and the backing plate 4 with a balanced instantaneous force, so that the protruding portion of the paper tube 15 is pushed in or contracted. Then, the end faces of the sheet-like material 14 and the end faces of the paper tube 15 are flush with each other, and the end faces are thus corrected.

In the illustrated example, since the saucer 2 is elastically supported by the buffer spring 10, the striking block 6
Loaded roll product 13' against impact in the event of a collision.
There is no risk of damage to the product because there is no slipping with the surface of the product, and the product can be returned to its original position reliably after the end face has been corrected.

When the end face correction is completed in this way, the apparatus is returned to the initial state shown in FIG. 1 by operating both the pneumatic cylinders 5 and 7 to the return side, and then the loaded roll product 13' is taken out from the saucer 2, the series of end face correction steps is completed, and the end face is placed on standby for the next step.

(Effects of the invention) The present invention has the configuration and functions as described above, and is capable of receiving the roll product 13 in a horizontal state on the receiving tray 2, and connecting the pressure-receiving fixing plate 3 and the backing plate 4. Since the roll product 13 is clamped from both end faces on each vertical plane and a striking force is applied to the backing plate 4 in the axial direction of the product, an average force is applied to the roll product 13 over the entire length of the end face. As a result, the end face modification to make the protruding heart tube 15 flush with the end face of the sheet-like material 14 is performed reliably and neatly without any problem of distortion or application of excessive force to some parts.

In addition, the present invention has the advantage that it is extremely simple in structure as it only needs to be a device that provides linear motion in the same horizontal direction to the saucer 2, the backing plate 4, and the striking block 6, and can be easily automated. There is.
