Description

[Detailed description of the invention] This invention takes out the screens one by one from the screen layer onto a roller conveyor, transfers them, temporarily stops the screens with a stopper to adjust the timing, and then transfers the screens to the paper machine. This invention relates to a screen edge bending correction device for a screen feeding machine, which corrects the bend when the side edge of the screen bends downward on a roller conveyor. It is something.

In conventional cage loading machines, if the side edge of the cage bends downward for some reason when the cage is taken out onto the roller conveyor, the cage is placed in the slightly bent state. There was a problem in which insertion errors occurred, causing the operation of the sieving machine and paper machine to stop, resulting in a halt to production capacity.

In particular, when used in a device that automatically performs everything from laver cutting to drying, there is a problem in that the operation of the entire device is stopped and the production capacity is significantly reduced.

Therefore, the purpose of this invention is to solve the above-mentioned problems. Even if the left and right ends of the cage taken out on the roller conveyor are bent downwards, the bent ends can be corrected and An object of the present invention is to provide a device for correcting the bent end of a paper sheeting machine, which is capable of eliminating insertion errors into a paper machine incorporated in a paper machine or a fully automatic seaweed manufacturing machine.

Next, embodiments of the present invention will be described based on the drawings.

1 is the machine frame of the sifting machine, 2, 2 are the left and right side plates fixed to the machine frame 1 so as to face each other, 3... are the left and right side plates 2,
A large number of feed rollers 2 are rotatably supported, and are rotated in the direction of the arrow by a drive motor (not shown) via a belt 4 suspended around the ends of these rollers.

These feed rollers 3... constitute a roller conveyor 6 that transports the nori paper baskets 5 in a direction parallel to the cage rods, and these feed rollers 3... The screens 5 are taken out one by one from the screen layer by a screen removal device (not shown).

Reference numeral 7 denotes a positioning plate attached to one side plate 2, which moves horizontally on the roller conveyor 6 by a biasing mechanism (not shown) (for example, a screw is provided on the circumferential surface of the feed roller, or the feed roller is arranged diagonally). The side edge of the screen 5 being moved is received to position the screen 5.

This positioning plate 7 is provided with a notch 7a to avoid interference with a correction piece to be described later.

8 is a safety cover. 9 is a stopper operating shaft rotatably supported on the side plate 2.2, 10.10 is a stopper support arm fixed to the stopper operating shaft 9, and 11 is a stopper fixed to the stopper support arm 10.10.

This stopper 11 is moved into and out of the cage transfer locus on the roller conveyor 6 in conjunction with the take-out of the cage 5 onto the roller conveyor 6 by the cage take-out device when the stopper operating shaft 9 is rotated by a drive motor (not shown). , which temporarily receives the front end of the screen 5 being transferred, and places it on the screen holder 12 of the paper machine.
A cage 5 is placed in the center of the cage.

The above-mentioned is a conventionally known staking machine, and the placed end bending correction device of the present invention has the following configuration in addition to such a staking machine.

Reference numeral 13 denotes a support rod whose both ends are fixedly attached to the left and right side plates 2, 2 and disposed below the cage transfer trajectory, and support members 14 and 14 are fixed to respective portions separated by appropriate intervals.

Reference numeral 15 denotes a pivot that is rotatably supported on the support 14 on the right side in FIG. ing.

Reference numeral 18 denotes a swinging arm pivotally attached to the support 14 on the left side in FIG. In conjunction with the swinging, the swinging arm 16 swings in a direction opposite to the swinging direction of the swinging arm 16.

Reference numeral 21 and 22 are correction pieces whose lower ends are fixedly attached to the upper ends of the swinging arms 16 and 18, and when the swinging arms 16 and 18 are swung from the solid line position to the imaginary line position in FIG. These tip portions are arranged so as to trace the lower surface of the side end of the screen 5 on the roller conveyor 6 while pushing it up slightly from the center toward the circumferential outside.

These correction pieces 21 and 22 are preferably made of an elastic material such as rubber in order to reduce damage to the lower surface of the screen 5, but are not limited to this.

Note that these correction pieces 21 and 22 may be formed integrally with the swing arms 16 and 18.

Reference numeral 23 denotes a drive mechanism for swinging the lever 17, which is constructed as follows.

That is, the camshaft 24 is rotatably supported by bearings 25 and 25 attached to the machine frame 1, and is continuously rotated in the direction of the arrow by a drive motor (not shown) via a belt 26.

A cam 27 is fixed to this camshaft 24.

Reference numeral 28 denotes a cam lever pivotally attached to the machine frame 1 via a pivot 29, which is biased downward by a spring 30 stretched between the machine frame 1 and the cam follower 31 attached to the intermediate part. It is pressed against the cam 27.

The tip of this cam lever 28 is connected to the lever 17 by the connecting tool 3.
2.33 and the rod 34 so that the interval can be adjusted, and while the cage 5 transferred by the roller conveyor 6 is received by the stopper 11, the lever 17
is pivoted downward, and while the screen 5 is not received by the stopper 11, the lever 17 is pivoted upward.

With the above configuration, when the drive motor is rotated and brought into operation, the feed roller 3 of the roller conveyor 6
... rotates in the direction of the arrow, and the screen take-out device takes out the screens 5 one by one from the tube layer onto the roller conveyor 6.

Also, in connection with the removal of the screen 5 by the screen removal device, the stopper operating shaft 9 is rotated reciprocally, and the stopper 11 is moved in and out of the screen transfer trajectory. Swings downward, stopper 1
1 is projected (raised) into the cage transport path
In the meantime, the correction pieces 21 and 22 are moved in an out-of-plane direction from the center side.

Therefore, the cage 5 taken out onto the roller conveyor 6 is immediately transferred to the left in FIG. 1, but on the way, it is stopped by the stopper 11 to adjust the timing of the cage placement.

Further, the screen 5 is laterally moved by the biasing mechanism, whereby the side ends of the screen 5 are brought into contact with the positioning plate 7, and positioning in the lateral direction is performed.

When the screen 5 is positioned and stopped in this manner, the swinging arms 16 and 18 of the placed end bending correction device swing from the solid line position to the imaginary line position in FIG.
The tip of the screen traces the lower surface of both ends of the screen 5 which is stopped by the stopper 11 while pushing up slightly from the center side to both outside sides, and if the side end of the screen 5 is bent downward, this Correct the bends as shown in A, B, and C in Figure 3.

In this case, even when the bent part of the screen 5 is in contact with the positioning plate 7 as shown in A, the correction piece 21 traces the screen 5 while pushing it up slightly as shown in B, so the bend in the screen 5 is can be modified as shown in C.

Further, the bends at both end portions can be corrected at the same time.

After that, the stopper 11 is retracted (lowered), the screen 5 is placed on the screen holder 12 of the paper machine, and the correction pieces 21 and 22 are placed on the screen holder 12 of the paper machine.
is returned to the center side until the next screen 5 is transferred.

Note that the present application is not limited to the above-mentioned embodiment, and correction pieces may be provided on the sliding body that slides from the center side of the cage transfer locus toward both outer sides.

As described above, in the present invention, a pair of correction pieces are placed in front of the stopper and reciprocate in the left and right directions with respect to the baton feeding direction in relation to the operation of the stopper. Since the lower surface of the side edge of the screen is traced from the center side to the outside of the surface, even if the side edge of the screen is bent downward when the screen is taken out from the tube layer onto the roller conveyor, The bend in the side edge of the screen can be corrected while the screen is stopped with a stopper and the timing is adjusted, and mistakes in insertion of the screen into the nori machine can be prevented and the nori production capacity can be reduced. There is an effect that can improve the situation.

In addition, as mentioned above, since the tip of the correction piece traces the lower surface of the side end of the screen that is stopped by the stopper from the center side to the outside, there is no need to separately stop the screen to correct the bend. It has the advantage that it can be implemented relatively inexpensively over conventional siege machines.
