Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for determining the required number of copies of thin materials such as newspapers and magazines that can be partially supported in a cantilever shape, which are transported in a scale-like manner with folds, seams, etc. facing up. This invention relates to a method and device for extracting thin materials such as newspapers.

Newspapers are sent out from a rotary press in piles on a conveyor, and during delivery, the required number of newspapers are pulled out for inspection. Newspaper is drum 1 of rotary press
Since two copies are printed by rotation, at least two copies are successively removed from the conveyor and inspected. Conventionally, such extraction was carried out manually or by using a extraction device described in Japanese Patent Publication No. 16762/1976, but in the former case, skill was required and the newspapers before and after were removed. In the latter case, when grasping the newspaper, the legs 4 shown in Figure 1 of the above publication may push down the newspaper being transferred and cause a delay in the initial stage. Because they moved in the same direction at the same speed, there was a risk of disturbing the arrangement of the newspapers in front and behind them.

The object of the present invention is to provide a method for extracting thin materials such as newspapers, which does not disturb the arrangement of newspapers, etc. before and after the newspapers, etc. when extracting them as in the past, and which is adjustable in accordance with changes in the number of copies to be extracted or the thickness of the newspapers, etc. We are in the process of providing equipment.

The lower clamping plate 40 is biased by the spring 39 so as to clamp the newspaper P between the lower clamping plate 40 and the claws 35 . The roller 41 attached to the upper end of the metal fitting 38 is attached to the support plate 1.
The clamping plate 40 is moved against the biasing force of the spring 39 by contacting the reverse ladder-shaped striker 42 fixed to the main body 3.
It is held in an open state (dashed line) that is inclined downward with respect to the lower surface of 1. In this open state, the clamping plate 4
The tip of 0 faces directly above the center of the newspaper P on the conveyor 1.

A push-up device 43 for pushing up the newspaper P on the conveyor 1 into a mountain shape is provided at the lower center of the conveyor 1 in the width direction. The push-up device 43 rotatably fits and supports a support fitting 45 on the boss portion of a sprocket 44 fixed to the rotating shaft 7, and a guide plate 46 having a semicircular tip and parallel sides is fixed to the fitting 45. The rollers and inner links of the endless chain 47 that are placed on the sprocket 44 are configured so that they fit into the end surface of the guide plate 46 and are guided, and the tips of the legs 48 are fixed to some adjacent links of the chain 47.

It is configured to push up the newspaper P into a mountain shape.

A cover plate 57 is attached to the upper end of the support plate 18 and the arm 56 fixed thereto, and its outer end is curved downward so as to cover the outer periphery of the sprockets 19 and 20. A guide rail 58 for guiding the roller 34 is fixed to the support plate 18.

Next, the operation of the present invention will be explained with reference to FIG.

Initially, the push-up roller 49 is located at the bottom of the chain 47 (FIG. 2), and from there it is pre-aligned with the sprocket 1 so that the hook 25 can advance and engage the driven roller 29a during movement to the newspaper push-up position.
The stopping position of the hook 25 is determined by adjusting the angular position in step 9.

(1) When the electromagnetic clutch/brake 3 is actuated by a newspaper grabbing command, the rotating shaft 7 operates the synchronous chain 12, the drive chain 24, and the chain 47.
is activated, the push-up roller 49 pushes up the newspaper P on the conveyor 1, and the hook 25 moves forward and approaches the position where it engages with the driven roller 29a (FIG. 6A).

(2) Since the push-up roller 49 moves at the same speed as the pushed-up newspaper, the series of newspapers P stacked in a scale-like manner moves with the part touching the roller 49 lifted up into a mountain shape without disturbing the arrangement. At some points, a wedge-shaped gap is created between the front part of the newspaper P that has been pushed up and the preceding newspaper that overlaps below it. When the pushing up reaches a certain value or more, the leading edge of the pushed up newspaper P1 rides on the clamping plate 40 of the scissors device 30a stopped directly above it, and the clamping plate 4 is moved by the conveying force of the conveyor 1.
0 and the main body 31.

(3) At the same time, the hook 25 moves to the driven roller 29a.
When the roller 41 of the scissors device 30a is disengaged from the striker 42, the spring 39 causes the clamping plate 40 to clamp the inserted newspaper P1 between the claws 36. It is pulled out from above the conveyor 1 while moving parallel to the conveyor 1 (FIG. 6b).

The time from when the newspaper P1 is inserted onto the clamping plate 40 to when it is clamped by the clamping plate 40 can be changed by adjusting the angular position of the sprocket 19, thereby making it possible to change the number of newspapers to be subsequently taken out.

The scissors device 30a then moves diagonally upward and pulls out the newspaper P1;
Since the rear part of conveyor 1 is relatively flexible,
It does not disturb the arrangement of other newspapers above. Around the end of the above-mentioned extraction, the push-up roller 49 sinks from the upper surface of the conveyor 1, and the newspapers P return to the flat stacked state again (FIG. 6C).

(4) When the scissors device 30a goes around the sprocket 20 and the rollers 34 fit into the guide rails 58 and move forward, the newspaper P1 slides on the cover plate 57, and the rollers 41 of the scissors device 30a move around the support plate 1.
When it rides on the upper striker 59 fixed to 8, the grip is released. At this time, the other scissor device 30b reaches directly below the striker 42, and its roller 41 operates the limit switch 60, thereby disengaging the electromagnetic clutch/brake 3 and stopping the chains 12, 24, 47.

This completes one extraction operation, and the entire device returns to its original state (FIG. 2).

The present invention has the above configuration, and since the push-up chain device moves at the same speed as the conveyor for transporting newspapers, etc. and pushes up the newspapers, etc. into a mountain shape, the arrangement of the newspapers, etc. on the conveyor is not disturbed by pushing up, and the newspapers, etc. are not disposed of. It is easy to adjust the push-up height depending on the thickness of the newspaper, etc., and the scissor device moves the front part of the pushed up newspaper, etc. onto the clamping plate due to the conveyor conveying force, and immediately after the movement, the newspaper, etc. Since the sheets are automatically clamped and pulled out in the same direction faster than the conveyor speed, and then pulled upwards, the scale-like arrangement of other newspapers on the conveyor is not disturbed, and the number of sheets to be pulled can be easily changed. There are other effects.
