Abstract

PURPOSE:To remove a part of sheet papers to be fed and process respective sheet papers by installing a guide which positions the sheet papers on a paper receiver for circular movement of the paper receiver to utilize the section positioned until the positioned sheet papers drop upon a paper discharging conveyer from the paper receiver. CONSTITUTION:Sheet papers S from a printing machine or the like are fed upon a paper receiver 7 one by one. As the fed sheet papers S travel, they are positioned by a guide 5 to keep the positioning condition until they are dropped from the paper receiver 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a paper ejecting device used in conjunction with a printing press or the like.

[Prior Art] Conventionally, a paper discharge device in a printing press or the like is composed of a so-called impeller having a plurality of arc-shaped receivers attached around the impeller, and a paper discharge conveyor connected to the impeller. Then, the pieces of filter paper that are intermittently sent in from a printing machine or the like are received by the receiving part of the impeller and decelerated, and then they are dropped onto a paper discharge conveyor and are discharged in a sashimi-like manner.

[Problems to be Solved by the Invention] In the above-mentioned conventional sheet discharging device, pieces of paper from a printing machine, etc. are continuously discharged directly onto a sheet discharging conveyor via an impeller. are overlapping like sashimi at irregular pitches. Therefore, when performing post-processing such as pasting another piece of paper onto a piece of paper, it is necessary to accumulate the pieces of paper on the paper discharge conveyor, transport them to another location, and perform the processing off-line. However, there is a problem in that processing paper pieces off-line in this way is inefficient.

The present invention has been made in view of the above problems, and
The purpose is to provide a paper ejecting device into which a device for processing and manipulating paper pieces ejected from a printing machine or the like can be incorporated.

[Means for Solving the Problems] In order to achieve the above object, the paper ejecting device of the present invention has a plurality of receiving portions arranged in an annular band-like body for receiving pieces of paper ejected from a printing machine, etc. a receiving part assembly that is attached at regular intervals; a driving part that circulates and moves the plurality of receiving parts by rotationally driving a band-shaped body in this receiving part assembly;
It is characterized by having a guide for positioning the piece of paper on the receiving part as the receiving part circulates.

1 Effect] In the paper discharging device having the above configuration, pieces of paper from a printing machine, etc. are fed one by one onto the receiver, and as the receiver moves, the inserted pieces of paper are positioned by the guide, and the paper pieces are positioned by the guide as the receiver moves. The positioned state is maintained until the object falls.

[Example] Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a schematic diagram showing an embodiment of a paper discharge device according to the present invention, and FIG. 2 is a perspective view showing the positional relationship between a receiving portion and a guide in the paper discharge device.

As shown in FIG. 1, the paper discharging device is disposed between a conveyor 1 and a paper discharging conveyor 2, which are connected to a folding machine of a printing press. It is configured to include a drive section 4 that drives the subassembly 3 and a guide 5.

The receiving part assembly 3 is made up of a pair of endless chains 6 which are belt-shaped bodies, and a plurality of single-toothed receiving parts 7 are attached at regular intervals. It is designed to receive Ding S one by one. Reference numeral 8 denotes a stop member that connects the receiving section 7 to the endless chain 6 and stops the signatures S introduced from the transport conveyor 1 on the receiving section.

The drive section 4 consists of upper and lower sub-blocks) 9 and 10, and the pair of endless chains 6 are strung between the sub-blocks) 9 and 10 and rotated to move each of the receiving sections 7 in circulation. It has become.

The power for this rotational drive is either transmitted from the driving part of the printing press or supplied by a separate motor. The driving speed of the endless chain 6 is controlled so that the receiving section 7 is fed one step while a portion of the signatures S are supplied from the conveyor 2.

The guide 5 is made up of a plurality of elongated plates 11, and each plate 11 is installed in a tapered shape between the single teeth so as not to interfere with the single tooth shaped receiving part 7. As the receiver 7 moves from top to bottom, the signature S on the receiver 7 is positioned at a fixed position. In order to facilitate positioning of the signatures S, the guide 5 is finely vibrated by a cam mechanism (not shown) or the like.

Next, the operation of the paper ejection device having the above configuration will be explained.

In FIG. 1, a signature S is conveyed from a folding machine of a printing press to a paper discharge device while being held by a conveyor 1. As shown in FIG. In this embodiment, the signature S is conveyed with its spine facing forward. The signature S that has been conveyed is on the conveyor l
It is thrown into the receiving part 7 from the end with great force, hits the stopper member 8, and is placed on the receiving part 7 with some bounce. Thereafter, as the receiving part 7 descends, it is driven toward the stop member 8 by the guide 5, and is finally positioned between the stop member 8 and the guide 5 at the lower end of the guide 5. As described above, the signature S is positioned at a fixed position on the receiving part 7. Then, the signature S remains positioned until the receiving portion 7 further descends and the signature S falls onto the paper discharge conveyor 2.

Although the present invention has been described above with reference to one embodiment, the present invention is not limited to the above-mentioned embodiment, and the detailed configuration may be variously changed within the scope of the claims. It is possible to implement it by

For example, in the above embodiment, the signature S is positioned only in the direction in which it is inserted, but if necessary, a similar tapered guide may also be provided in a direction perpendicular to the direction in which the signature S is inserted for positioning. You can do it like this.

Further, in the above embodiment, the receiving part 7 moves from top to bottom with respect to the conveyor 1, but it may be moved from the bottom to the top if necessary. A guide 5 is attached to the side opposite to the conveyor 1 (on the left side in FIG. 1) to position the paper pieces S on the receiving section 7.

Furthermore, in the above embodiment, it is assumed that the signatures S are conveyed while being held by the conveyor 1, but as shown in FIG. The same effect can be obtained even if

Furthermore, in the above embodiment, each receiving part 7 is attached to a pair of endless chains 6 using a locking member 8, but as shown in FIGS. It is also possible to attach each receiving part 17 perpendicularly to one side of the rotating surface of the endless chain 16.

[Effect of chucking] As explained above, according to the paper discharging device of the present invention, the positioned state of the paper piece positioned by the guide is maintained until it falls from the receiving section to the paper discharging conveyor. Therefore, this positioning section can be used to extract part of the paper pieces and process them into individual pieces of paper.
By incorporating a device that performs post-printing processes into the paper ejecting device, work efficiency can be improved.
