Abstract

PURPOSE:To make paper holdable in a way of smoothly rocking each bin vertically even case of installing a lot of bins, by installing plural number of supporting parts supporting a low of bins free of vertical rocking motion at regular intervals in vertical directions, in case of a copying machine or the like. CONSTITUTION:Each of horizontal rods 24 and 25 serving as both first and second supporting parts is horizontally installed in symmetrical side plates 11 and 12, and the horizontal rod 24 comes into contact with the underside of a tenth bin 1510 while the horizontal rod 25 with the underside of a twentieth bin 1520 respectively, supporting bins 151-1510 in a first group and bins 1511-1520 each separately. Therefore, bin's dead load acts on directions Y1 and Y2 being orthogonal with a line X1 connecting the horizontal rod 24 and the center of gravity G1 as well as a line X2 connecting the horizontal rod 25 and the center of gravity G2, and when the bin 15 to be vertically rocked by a Geneva mechanism drops down, a bin 16 will not be pressed to each side of longitudinal grooves 13 and 14 with strong force so that the bin is able to drop down so smoothly at will.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheet collating device that sorts and stores sheets discharged from a copying machine or the like into a large number of bins.

BACKGROUND ART As shown in FIG.
3 i7) Hi 4 Slide into the bottle 3
At the same time, the support member 5 is brought into contact with the lowermost bin 3, and the cutout part 7 of the Geneva 6, which rotates and moves up and down, is fitted into the bin 4. A paper collating device that is designed to swing.

Problem to be Solved by the Invention Since the center of swing of the bottle 3 is the support part 5, the weight of the bottle 3 acts on the side surface of the vertical groove 2, and the sliding resistance of the bottle 4 increases, causing it to swing downward. (pushing down) the bottle 3 may not fall freely.

This becomes more noticeable as the number of bins 3 increases.

In other words, the weight of the bottle acts in the direction Y perpendicular to the straight line X connecting the center of gravity G of each hip 30 and the support part 5, and as the number of bottles 3 increases, the center of gravity G moves away from the support part 5 and the angle α1 of the straight line As a result, the angle α between the direction Y, in which the bottle's own weight acts, and the vertical groove 2 becomes large, and the bottle 4 is strongly pressed against the side surface of the vertical groove 2, so that the bottle 3 may not fall freely.

Means and Effect for Solving the Problem A plurality of support parts that support the bottles in a vertically swingable manner are provided at intervals in the vertical direction, and a large number of bottles are divided into several groups, and each support part is separately provided. As the number of bins increases, the bins can fall smoothly and freely, and even in paper collating devices equipped with a large number of bins, the bins can be smoothly swung up and down to sort and store paper. What I did.

Embodiment FIG. 2 is a longitudinal sectional view, and FIG. 3 is a plan view. The main body IO has a bottom wall 10α, earthen walls (not shown), and left and right walls +06, +Ot.
! And before and after I! lod, log,! : It is box-shaped, and the front and back are 11110d.

101 has left and right side plates 11. +2 is constructed, and these left and right side plates 11. +2 left and right vertical grooves 13. The first to 20th bins 151 to 152 degrees are slidably inserted into +4, and the notched grooves 18 of Geneva I7 are fitted to these bins 16 so that the bins 15 can be swung up and down. It is.

Reference numeral 19 indicates a paper conveyance belt, and 20 indicates a sorting member for feeding the paper into each bin 15.

As shown in FIG. 4, the Geneva 17 is movable up and down along the vertical groove 21 of the left side plate 11, and is rotatably supported by a support 22, with a lead screw 23 screwed into the sono support 22. Yes, when the lead screw 23 is rotated in the forward and reverse directions, the support 22 moves up and down, and the Geneva 17 moves up and down. At the same time, by rotating the Geneva I7 in the forward and reverse directions, the bin 16 fits into the notched groove 1g, and the bin 3 is moved up and down. It is configured to swing up and down.

Note that this structure is the same as the conventional one.

The left and right side plates 11 and 12 have first and second horizontal bars 24 and 25 that serve as first and second supporting parts, and the first horizontal bars 24 and 25 are horizontally suspended from each other.
is on the bottom surface of the 10th bin 15Io, and the second horizontal rod 25 is on the 20th
The first to 20th bins 151 to 15 . o to the 1st to 10th bins + 5. ~15
．． o's 1st group and 11th to 20th bins 15m, ~15□G
The bins of the first and second groups are divided into the first and second groups.
It is supported separately by horizontal rods 24 and 25. 1) Since it is like this, the 1st to 10th bins 15. ~151o
is supported by the first horizontal rod 24, and the 11th to 20th hinges 151
1-15. Since o is supported by the second horizontal rod 25, the straight line X1 connecting the first horizontal rod 24 and the center of gravity G1, the second horizontal rod 25
Since the weight of the pin acts in the direction Y, Y, which is perpendicular to the straight line connecting the center of gravity a and the center of gravity a, the bottle 16 is not pressed against the side surface of the vertical groove 13, 14 with a strong force.
The bottle can freely fall smoothly.

In other words, as shown in FIG. 5(α), there are two supporting parts 24.
and 25, the angle α between the two straight lines X, , X, is small, and the pin self-weight action direction Y1. Y! The angle α becomes smaller, but as shown in FIG.
．． 25, the angle α of the straight line X.

is large, and the angle α of the bottle self-weight acting direction Y also becomes large.

Effects of the invention The angle of the straight line connecting the center of gravity and the support part can be made smaller, and the angle in the direction in which the bottle's own weight acts becomes smaller, so the force with which the bottle hits the vertical groove is reduced, allowing the bottle to fall smoothly and freely. Q-kill.

Therefore, even in a paper collating device equipped with a large number of bins, the bins can be smoothly swung up and down to sort and store paper.

Claims (1)

[Claims] A large number of bins 15 are made vertically movable along vertical grooves 13 and 14 via bins 16, and the bins 16 are moved up and down by a Geneva 17 to sequentially swing the bins 15 up and down. In addition, the paper combining device is characterized in that a plurality of support portions 24 and 25 for vertically swingably supporting the bin 15 are provided at intervals in the vertical direction.
