Abstract

PURPOSE:To achieve good stacking performance in paper stacker by providing a sliding swash board on the floor board to lift the front section of paper then moving a central projection member to the center between the swash board and back plate. CONSTITUTION:A rotatable central spiral shaft 11 and a pair of guide bars 10 are secured through three sets of fixed flanges 9a, 9b to the fixed floor board 2. The floor board 2 has a sliding swash board 5 and a central projection 3. The swash board 5 will slide in longitudinal direction to lift the front face of continuous paper 1 thus to prevent slip down while the central projection 3 will prevent collapse in the center of paper. The swash board 5 can be moved to the position suitable to the paper width through rotation of handle 6. Consequently, the central projection 3 will move to the central position between the swash board 5 and the back plate 4 through balance of the springs 12a, 12b wound over the circumference of the spiral shaft 11 and the guide bar 10 thus to realize good stacking.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a paper stacking device in a printer device that uses continuous form paper.

[Conventional technology]

In general, for those that do not have a separate stacking device,
A conventional stacking device is shown in FIG. In the figure, the stacking device is integrated with a housing 13, has a floor plate 2 having a central protrusion 3 at the paper drop position, and has a back plate 4, and the continuous paper 1 is placed on the back plate 4. It was an extremely simple method of stacking them on the floorboard 2.

[Problems to be solved]

In conventional paper stacking devices, the quality of the stacking performance is greatly affected by the slight difference in the position of the start of folding of the continuous paper 1. Since there is no support, there is a problem in that when the continuous paper 1 exceeds a certain height, a stacking failure occurs in which it slides down to the front.

In addition, the central convex portion 3 is originally intended to prevent the central part of the continuous paper 1 from collapsing and obtain good stacking properties, and if it is not always located at the center of the fold of the continuous paper 1, it will not stack well. can't get any effect. In this respect, when the central convex portion 3 is fixed, there is also the problem that folding of the continuous paper 1 that can be stacked is limited.

[-One Step Solution to Eleven Points] The present invention solves the above-mentioned problems and provides a paper stacking device having a horizontal floor plate and a vertical back plate, and folding continuous paper on the floor plate. , a diagonal plate for lifting the edge of the paper is provided on the opposite side of the back plate on the floor plate so as to be slidable back and forth in the direction of the back plate, and a central convex member for lifting the center of the test paper is provided as a core. The central convex portion is provided between the back plate and the diagonal plate so as to be slidable back and forth in the direction of the back plate, and springs are interposed between the central convex member and the rear plate and the diagonal plate, respectively. It is configured so that it is always moved and set to a substantially central position between the back plate and the diagonal plate, with a delay h to the movement of the diagonal plate.

That is, in the present invention, by providing a sliding diagonal plate on the floorboard, the front part of the paper is lifted up to prevent the paper from sliding down, and the central convex member is moved diagonally in conjunction with the sliding diagonal plate. By moving it almost to the center of the board and back plate, it will always support the center of the paper even if the paper is in different sizes [to obtain good stacking properties, and it will be convenient because it can be used with various types of paper]. .

〔Example〕

Next, one embodiment will be described with reference to FIGS. 1 and 2.

Figure 1 (2) and [F]) are respectively a front view of an embodiment of the paper stacking device according to the present invention, and IB-I in Figure 1 (4).
A longitudinal cross-sectional side view along line B, IC2 diagram is a diagram showing details of the spiral shaft.

In the figure, the fixed floor plate 2 has three sets of fixed flanges 9a.

9bK, rotatable central spiral shaft)
11 (details shown in FIG. 2) and a pair of guide bars 10 on both sides are fixed.

The floorboard 2 has a sliding diagonal board 5 and a central protrusion 3.

The sliding diagonal plate 5Ii slides and moves in the longitudinal direction of the spiral shaft 11 and the guide bar 1O by a structure described later, and lifts the continuous paper l, that is, the front surface of the paper, to prevent the paper from slipping off. The central convex portion 31- is used to prevent the central portion of the paper from collapsing.

By rotating the handle 6, the sliding diagonal plate 5 is placed in a suitable position within the paper in the front and back direction, that is, in FIG.
) It is possible to move without moving in the right direction at medium pressure. This moves the spiral shaft 7) 110 on the spiral groove of the spiral shaft ll.
As the screw rotates, the screw 7 inside the support part of the sliding diagonal plate 5
This is because it has a mechanism that allows it to pass through.

Following this, the central convex part 3tl spiral shaft) 11
b and the springs 12a and 12b wound around the circumference of the two guide bars 10, so that the springs 12a and 12b are always positioned approximately at the center of the distance between the sliding diagonal plate 5 and the back plate 4 (movement). .

As a result, even if the continuous paper l is stacked and its height increases, the front end side of the continuous paper l is lifted by the sliding diagonal plate 5, so that inconveniences such as slipping can be prevented. Even if the folding of the continuous paper l is different, the center convex part 3
It is possible to perform good stacking by always moving and setting the center position of the folding machine in correspondence with the folding machine, and it is convenient because it can correspond to various folding machines.

[-Effect of invention]

As explained above, the present invention lifts the front part of the paper by providing a sliding diagonal plate on the floorboard to prevent the paper from slipping, and the central convex member is moved in conjunction with the sliding diagonal plate. Because it moves to approximately the center of the diagonal plate and the back plate, it is possible to always support the center of the paper and obtain good stacking properties even if the paper is in different sizes. This has the effect of being compatible and convenient.
