Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides high-speed printing (150,000 copies per hour) from a newspaper rotary press.
The present invention relates to a device for extracting newspapers being conveyed in order to inspect the printed surface of the newspapers that are continuously discharged, for example, the density of ink and whether the printing is clear.

[Conventional technology and its problems]

Conventionally, the above-mentioned sampling work has been carried out manually by a skilled person, which is extremely dangerous and requires a large mental burden.

In order to solve this problem, Japanese Utility Model Application No. 52-1203 proposes a device that automatically performs paper inspection work.

However, this device had the following problems.

That is, in this device, the guide claws were lowered regardless of the position of the folds in the newspaper, so the guide claws sometimes directly hit the folds in the newspaper, resulting in paper jams.

[Problem that the invention seeks to solve]

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus that can solve the above-mentioned problems and can accurately and safely sample sample samples.

[Means and actions for solving problems]

The paper inspection and sampling device of the present invention collects newspaper discharged from a rotary press and has a crease at the front end in the conveyance direction.
a conveyor belt that conveys the newspaper with the folded portion superimposed on the trailing edge of the preceding newspaper; A swinging arm extending toward the upper surface of the belt, a pair of delivery rollers arranged at the tip of the swinging arm so as to be able to pinch the folded portion of the newspaper, and rotationally driven by a drive section; a guide that is attached to the movable arm and has an opening located downstream in the conveying direction from a portion where the newspaper is sandwiched between the pair of feed rollers, and discharges the newspaper fed out from the pair of feed rollers to the outside of the conveyance line; The feed roller is disposed near the feed roller, has its base end facing the opening of the guide, has its tip facing downstream in the conveying direction, and is driven so that its tip approaches the conveying surface side of the conveyor belt. a guide claw that is rotatable by a section and connected to the swing arm; and a guide claw that is provided on the downstream side in the conveying direction opposite to the delivery roller and the guide claw, with its tip approaching the conveying surface side of the conveyor belt. and a stopper that is rotatable by a drive unit and that can engage with the folded portion of the newspaper, and the swing arm is oriented in the conveying direction so that its tip is away from the conveyor when it is in its standby position. furthermore, the swinging arm and the stopper are swung to a position where the pair of delivery rollers face the crease after a certain period of time after the fold is restrained by the stopper; It is characterized by having an interlocking relationship in which the arm is rotated and then the restraint by the stopper is released.

When the paper to be tested is removed, due to the interlocking relationship between the swing arm and the stopper, the stopper goes first and restrains the folded portion of the newspaper to stop the newspaper on the conveyor. Thereafter, the swinging arm rotates and the pair of delivery rollers are set at a position facing the folded portion of the newspaper, and the drive unit is ready to send out the newspaper in the guide direction. Then, when the restraint by the stopper is released, the folded portion enters into the delivery roller using the feeding by the conveyor, and the newspaper is delivered into the guide by rotation of the delivery roller.

In this way, the newspaper on the conveyor belt can be extracted by the swing arm moving from the downstream side in the conveyance direction to the extraction position, and the newspaper being scooped up from the fold by the delivery roller.
Therefore, compared to the case where newspapers are removed by cutting through the flow of continuously conveyed newspapers, it is possible to perform inspection and sampling without disturbing the flow of newspapers.

2 to lower the guide claw 30, and
0 is lowered, the stopper 61 is raised.

The newspaper 72 is sandwiched by the rotation of the first and second delivery rollers 17 and 19, and after confirming that the paper is pinched, the swing frame 15 is rotated to the newspaper removal position. Thereafter, when the newspaper 72 is taken out from the guide 40, the sampling of the paper to be tested is completed.

In this way, with respect to the continuous flow of newspaper 72, after a part of the newspaper 72 is stopped by the stopper 61, the folded portion 73 is removed from the flow by the guide 30.
can be scooped up and sent to the guide 40. Therefore, compared to the case where a rod or the like is cut into the flow of newspapers 72 to remove the test paper, the flow of other newspapers 72 is not disturbed, and the test paper can be quickly extracted.

〔Effect of the invention〕

In the present invention, since the folded portion of the newspaper is scooped up and fed into the guide, the newspaper can be pulled out more reliably and quickly than when a rod or the like is cut through a continuous flow of newspaper to pull it out. can. For this reason, the rows of newspapers on the conveyor belt are not disturbed during paper inspection, and efficient newspaper printing is possible without causing problems in processing in subsequent lines.
