Description

  The present invention relates to a collation apparatus, and more particularly to a collation apparatus such as a newspaper advertisement collation machine.

  In a collation apparatus such as a newspaper advertisement collation machine, in order to sandwich a plurality of papers such as advertisements in a newspaper, for example, the same type of advertisements and papers are stacked and held one by one from the top layer side. A configuration having a plurality of paper feed shelf units that feed paper one by one is usually used (see FIG. 9).

  In such a collating apparatus, since the paper is discharged and fed one after another in each paper feed shelf unit (101 to 10n), the replenishment is performed when the remaining amount of the stacked and held paper decreases. Is required. As an example of this replenishment method, there is an example in which a rear end side of the stacked and held (sometimes simply referred to as stacking) paper is lifted, and a new paper is sandwiched underneath. This will be described with reference to FIGS. 9 and 10 (a) and 10 (b).

In this example, a plurality of paper feed shelf units (101 to 10n) are arranged in a step shape, and each paper feed shelf unit (101 to 10n) has its rear end side raised to the upper surface side. Auxiliary paper feeding plates (12, 13) that can be hooked and held on the upper shelf are arranged. During the stacking operation, the rear end side of the already loaded paper 900 is lifted by the auxiliary paper feeding plates (12, 13), and the stacking paper is replenished to the lower side (for example, Patent Document 1).
For reference, a control system block diagram is shown in FIG.
Japanese Utility Model Publication No. 4-138063 (FIGS. 1 and 3)

In such a collating apparatus, a number of paper feed shelf units are provided in parallel in stages, and the sheets are discharged and fed sequentially from each stage. Since the remaining amount is reduced and the paper is fed at a high speed, the replenishment may not be in time and the apparatus may stop due to the absence of paper.
Once stopped, the device must be restarted, which takes time to accelerate the main motor and reduces efficiency.
In addition, since there is a possibility that a bundle that does not include paper that has run out of paper immediately before stoppage of paper is formed, one or several sets of bundles created immediately before stoppage must be inspected. There is a problem that it takes time to replenish paper that is insufficient as a result.

In view of the problems in the background art described above, the object of the present invention is to detect that the remaining amount of paper has decreased before the absence of paper is detected, and to perform the feeding operation of each shelf without stopping the main motor. An object of the present invention is to provide a collating apparatus that can stop and replenish paper.
