Abstract

PROBLEM TO BE SOLVED: To make improvements in productivity as well as to prevent any possible paper loss from occurring. SOLUTION: A first paper receiving lever 17 is made to be free of retractable motion in an A to B direction between a refuge position at the outside and an operating position at the inside of a dropping route of a sheet of paper at a position where a front stopper is installed. Paper 30b conveyed by a claw rod 14 of a conveyed chain 13 is temporarily received by both first and second temporary paper receiving levers 17 and 27. Then, the second temporary paper receiving lever 27 turns round in the C direction with an operating shaft 24 as the turning center, turning to a tilting state from an upright state in order to advance into the operating position.

題もあった。However, in the above-described conventional sheet ejection device of the sheet-fed printing press, since the sheet receiving member is structured to enter substantially horizontally with respect to the paper drop path, the sheet ejection member is ejected. Depending on the speed and the discharge state, the paper may drop in a wave-like manner in the paper width direction, so that all the paper receiving members arranged in the paper width direction may enter below the falling paper. If you can't do this, you may get across two or more sheets of paper. In this case, not all of the paper receiving members can support the lower side of the paper as a whole, and the edge of the paper hangs downward from the paper receiving member.
For this reason, the paper loaded on the paper receiving member collapses, and complicated work is required to correct the collapse of the cargo, resulting in a decrease in productivity. Further, when the paper receiving member is inserted, the front end of the paper receiving member easily hits the side surface of the paper, and if it hits, the paper is rolled up, resulting in a waste paper.

In a paper discharge device of a sheet-fed printing press provided with a temporary paper receiving member movably supported between an operating position for receiving and falling paper, the temporary paper receiving member is erected at a retracted position, It is rockably supported so that it will lie down in the retracted position, and the temporary paper receiving member will push it downward without contacting the side of the paper immediately before it is temporarily received, and securely enter the first paper to be temporarily received.

Curved to the side, the paper 30 is released from the grip
Of the plate removing plate 3 without the paper edge of the paper catching on the paper receiving portion 27a.
1. Drops smoothly on top. When a predetermined amount of paper 30 is loaded,
When the paper stacking table is slightly lowered and the air cylinder 20 is operated to move the operator 21 in the A direction in FIG. 2, the operating shaft 24 is rotated in the C direction via the levers 22 and 23. The second temporary paper receiving lever 27 is the holder 26.
As shown in FIG. 4 (a), it rotates in the C direction integrally with and is positioned at an operating position inside the drop path of the paper 30.

Since a is pushed down by the lower surface of the second temporary paper receiving lever 27, it is reliably separated from the temporarily received paper 30b. Therefore, since the second temporary paper receiving lever 27 is inserted below the paper 30b to be temporarily received without entering below the paper 30a, a plurality of second temporary paper receiving devices arranged side by side in the paper width direction are provided. Since all of the levers 27 support the temporarily received paper 30b as a whole, the end of the temporarily received paper 30b does not hang down from the second temporary paper receiving lever 27.

る。Further, at this time, after the paper 30a is reliably separated, the second temporary paper receiving lever 27 advances below the paper 30b on which the temporary paper is received, and the paper 30b is placed on the paper receiving portion 27a. Since the second paper receiving lever 27 does not come into contact with the side surface of the paper 30b, the paper 30b is not wound up and is lost. Further, since the operating shaft 24 that supports and rotates the temporary paper receiving levers 27 is horizontally supported between the support plates 25, the leading ends of the paper receiving portions 27a are not aligned when the plurality of temporary paper receiving levers 27 are in the upright state. Never becomes,
Moreover, since all the temporary paper receiving levers 27 fall down in the C direction, the paper 30a and the paper 30b are reliably separated.

The paper 30c which is temporarily received by the receiving portion 27a and the first temporary paper receiving lever 17 and is further conveyed is also temporarily received by the first and second temporary paper receiving levers 17 and 27.

る。While the first and second temporary paper receiving levers 17 and 27 are temporarily receiving the paper 30b in this manner, the plate removing plate 31a is inserted in the D direction along a guide member (not shown). . At this time, as described above, a plurality of the second temporary paper receiving levers 27 are provided in the paper width direction of the paper 30, and the second temporary paper receiving lever 27 is provided in the horizontal direction on the upstream side of the paper 30 in the carrying direction and orthogonal to the carrying direction A of the paper 30. The first temporary paper receiving lever 27 is temporarily received by fixing the operation shaft 24 to the second temporary paper receiving lever 27 so that the second temporary paper receiving lever 27 can swing. Since the first paper sheet 30b that surely enters the paper sheet 30b is supported and the first paper sheet 30b that is temporarily received is entirely supported, the edge of the first paper sheet 30b that is temporarily received may hang down from the second temporary paper sheet receiving lever 27. Therefore, when the plate removing plate 31a is inserted, it is prevented that the load collides with the side surface of the paper 30 on the second temporary paper receiving lever 27 and the load collapses, thereby improving the productivity.

定する。In the present embodiment, the second temporary paper receiving lever 27 is fixed to the operating shaft 24 so as to rotate the operating shaft 24. However, the present invention is not limited to this, and the operating shaft 24 may be a frame or the like. Alternatively, the second temporary paper receiving lever 27 may be rotatably supported with respect to the operating shaft 24, and the second paper receiving lever 27 may be erected and laid down by an air cylinder or the like. Further, although a plurality of second paper receiving levers 27 are provided, the number of the second paper receiving levers 27 may be one. By forming the second paper receiving lever 2
An effect similar to that of providing a plurality of 7 can be obtained. Further, although the operating shaft 24 is one, it may be divided into a plurality of operating shafts 24. In that case, for example, the operating shaft 24 is divided into two, and the two operating shafts 2 are divided.
If the outer ends of the second temporary paper receiving levers 27 are arranged so as to incline upward, when the operating shafts 24 rotate and the second temporary paper receiving levers 27 fall down, the tip ends of the second temporary paper receiving levers 27. Contacts the paper 30 stacked on the plate removing plate 31 so as to move from the center side of the paper toward the outer side in the width direction of the paper,
Air that has accumulated between the sheets of paper 30 can be efficiently released from the paper 30, so that the stacking of the paper 30 on the planing plate 31 is stabilized.

損紙の発生が防止される。As described above, according to the present invention, in the sheet discharging device of the sheet-fed printing press, the temporary sheet receiving member is swingably supported so as to stand up in the retracted position and fall down in the operating position. By doing so, when the temporary paper receiving member enters, the paper just before the temporary paper receiving member temporarily receives the paper is pushed downward to surely separate from the first paper to be received, and the temporary paper receiving member Since the first paper to be supported is supported so as to be guided downward, the first paper to be temporarily received does not come into contact with the side surface of the first paper to be wound up, and thus the occurrence of waste paper is prevented.

When the paper is in the retracted position, the leading edge does not become misaligned, and all the temporary paper receiving members fall down, so the paper that is temporarily received and the previous paper can be reliably separated. Be seen.
