Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll paper manufacturing apparatus for office machines, and more particularly to a roll paper manufacturing apparatus for manufacturing so-called register rolls, that is, roll recording paper used in printers of register devices.

[0002]

2. Description of the Related Art The above-mentioned cash register roll is delivered as a product after winding a paper having a predetermined width dimension on a pre-cut paper tube for a predetermined length in a small winder process. Normally, in the small split winder process, about 14 to 28 products are dispensed onto the table after completion of the process in each cycle. These semi-finished products are printed with a manufacturing lot number etc. on a predetermined surface and sent to the next process.However, the paper with the predetermined width dimension and the axis of the pre-cut paper tube are used. It is unavoidable that some errors occur in the directional dimension, and in the winding process described above, a deviation of 2 to 3 mm or more may occur at the paper edge.
Further, if the left and right balance of the upper core pressing roll is unbalanced during winding, the edge of the paper will be misaligned to the side where the pressure is weak, so it is necessary to correct the side surface of the product. For these measures,
Conventionally, the correction work is set as a necessary process, and the work is performed by hitting it with a hammer manually or by mechanical force such as a punch press using the flywheel effect.

[0003]

In any of these correction work, that is, when hitting with a hammer manually, and when mechanical force such as punch press is used, the load is an impact load, so that a stable finished surface cannot be obtained. There was a drawback that it could not be obtained. In addition, since there are front and back sides in the rewinding direction of the cash register roll, it is necessary to manually sort and arrange the cashier rolls scattered on the dispensed table for printing in the next process. In both the case of hitting and the case of using mechanical force such as a punch press, the load is 1500 to 2000 kg, which is a shock load, so noise is large, and in the case of human power, fatigue of the operator is also large. there were.

Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide a correction process centering on a hydraulic cylinder, which is conventionally corrected by an impact load by a human hand or the like. Another object of the present invention is to provide a roll paper manufacturing apparatus capable of automatically correcting misalignment of paper end surfaces on both sides of a roll paper for register or the like and projection of a paper tube by the above roll paper manufacturing apparatus. Also, after the roll paper is finished by the correction process, the roll paper is laid down 90 degrees and sent to the next process, which makes it easier to perform the front and back sorting process for printing the next process and packing the case. To provide a device.

[0005]

According to the present invention, the above-mentioned problem is solved by the first pusher device for pushing out the roll paper sequentially arriving at a predetermined position by the carry-in conveyor toward the next process, and by the first pusher device. When the rolled roll paper is placed, the falling discharge plate that discharges the rolled paper to the next process, and the product stop stopper cylinder device and the roll that stop the roll paper that is discharged from the falling discharge plate at a predetermined position A pressing device including a second pusher device that presses the side surface of the paper, a 90 ° reversing device that rolls the roll paper discharged from the pressing device sideways by 90 ° and sends it to the next step, and the first pusher. An apparatus, a second pusher device, and a control unit that controls the product stop stopper cylinder device in accordance with the movement of the roll paper manufacturing process. The falling discharge plate and the 90 ° reversing device are both solved by using an inclined surface.

[0006]

[Function] The pusher, which is the actuator of the push-in cylinder for product loading, pushes out the roll paper that sequentially arrives at the predetermined position by the carry-in conveyor, and it rolls down on the falling discharge plate, which is an inclined surface of about 5 °, to stop the product. It is stopped by the stopper device that is the actuator of the stopper cylinder device. When the side surface of the roll paper is pressed by the side surface hydraulic pusher to make it flat, the stopper device descends, and the roll paper is sent to the next step while being turned sideways by 90 ° by the 90 ° reversing device. The push-in cylinder for product loading, the hydraulic pusher for side press, and the stopper cylinder for product stop are controlled by the control unit at predetermined timing according to the movement of the roll paper manufacturing process. Is obtained,
Since the front and back sides of the next process are aligned, it is possible to perform highly efficient production.

The pusher 3 of the first pusher device 11, which is a push-in cylinder for loading the product, is actuated to the register roll 20 stopped at b, and a force is applied so as to push it in the direction of arrow A in FIG. The pushed-out registration roll 20 is sent to the press device 4, and is rotated by using a pair of fall discharge plate guides 6a and 6b provided in the press device 4 as guides, and a fall discharge composed of an inclined surface of about 5 degrees. It falls on the work plate 6 and is discharged.

The discharged registration roll 20 is rotated in the direction of arrow B in FIG. 4, and is regulated by the stopper device 5 projecting from the product stop stopper cylinder 13 as an actuator, and the end of the falling discharge plate 6 and A press device base 23 on which the fall discharge plate 6 is mounted,
It stops at a position in contact with the stopper device 5. In this state, the circular arc is in contact with the above-mentioned three points, so that the state is extremely stable.

In this state, the second pusher device 1 which is the hydraulic presser for the side press provided in the press device 4 is provided.
2 operates to flatten the side surface of the registration roll 20. That is, the second pusher device 1 on the press device base 23
The pusher 22 held by 2 is operated by hydraulic pressure, and pressing is performed so that the register roll 20 is sandwiched between the pusher 22 and the restriction member 24 also mounted on the press device base 23 at a position opposed thereto.

Upon completion of this pressing, the stopper cylinder 13 for stopping the product is actuated, the stopper device 5 is lowered, and the registration roll 20 has a sloping surface which is twisted by 90 degrees and two ridges twisted along the sloping surface. By the reversing device 7 having a guide rail of 90 degrees, it is placed on the discharge printing conveyor 8 in a state of being laid down in the direction of arrow C in FIG. 4 and sent to a printing process (not shown).
