Description

[Detailed description of the invention] This invention is a storage bin for a sorter that is connected to a copying machine and uses a movable deflection unit to distribute paper sent by a conveying means into a number of storage bins and to classify the paper. This invention relates to a paper alignment mechanism for paper in a paper machine.

The paper ejected into the storage bin by the ejection roller of the deflection unit is ejected at a considerable speed, so even after it leaves the ejection roller, it moves forward due to inertia. There are disadvantages in that it is difficult to remove the paper, and it takes time and effort to align the paper after taking it out.

Conventionally, the method of aligning the sheets ejected into the storage bin is to tilt the storage bin upwards in the front, and then the paper that has reached the front slides back on the bottom plate of the storage bin under its own weight, and the trailing edge of the paper is placed behind the storage bin. The paper sheets fed in one after another were aligned by being brought into contact with the end wall.

However, if the paper is charged with static electricity, it will repel the paper underneath, float up or stick to it, and instead of sliding straight down backwards, it will move left and right, often resulting in lateral misalignment. be.

As a means to solve this problem, we mechanically changed the inclination of the storage bin in the front-rear and left-right directions, so that the paper could slide on the bottom plate of the storage bin and follow the rear end wall and one side wall of the storage bin. However, this requires a complicated mechanism, which inevitably increases the size and cost of the device, and also requires a device that automatically adjusts according to each size. , what if I do it manually?
There are disadvantages such as the need for a large number of units.

In view of the above-mentioned problems of conventional paper alignment mechanisms, this idea allows the paper to be ejected one after another into the storage bin to be moved forward and backward without any trouble using a simple mechanism, regardless of the size of the paper or whether it is charged or not. To provide a paper alignment mechanism capable of aligning left and right sides.

To explain this invention based on the drawings shown in the embodiment, as shown in FIG.
,1.

,...1. are arranged one above the other with an appropriate upward slope.

A conveyor belt 2 is provided which is driven vertically along the paper entrance side of the storage bins 1, 1, . ing.

The deflecting unit 3 is provided with a deflecting plate 4 and a pair of ejection rollers 5, and the deflecting unit 3 is provided with a deflecting plate 4 and a pair of ejection rollers 5, and the deflecting unit 3 is provided with a deflecting plate 4 and a pair of ejection rollers 5.
is deflected and discharged into the storage bin 1 located at that position.

As shown in FIG. 2, each storage bin 1 has a lever 8 that is rotatably pivoted along the bottom plate 1a around a stepped screw 7 provided on the bottom plate 1a near the back side when viewed from the operator. supported.

There is an end plate (paper alignment member) 9 at the tip of the lever 8.
is rotatably mounted.

Details of how to attach the lever 8 and the end plate 9 are shown in FIGS. 3 and 4.

The end plate 9 passes through an escape hole 1b formed in the storage bin bottom plate 1a and projects upward from the storage bin bottom plate 1a.
It is designed to be able to swing freely within the range of the escape hole 1b.

The position and shape of the escape hole 1b and its positional relationship with the shaft 7 are as shown in FIG. The leading edge of the escape hole 1b shall be provided as close as possible to the front end wall 1e of the storage bin.

Further, the swing shaft 7 of the lever 8 is positioned close to the storage bin side plate on the back side when viewed from the operator, and slightly forward of the extension line of the rear edge of the escape hole.

Therefore, when the lever 8 swings along the bottom plate 1a around the shaft 7, the end plate 9 moves in an arc around the shaft 7 within the range of the escape hole 1b, and the end plate 9 moves in an arc shape around the shaft 7, and the end plate 9 moves in an arc shape around the shaft 7, and the end plate 9 moves in an arc shape around the shaft 7.
As it moves backward from b, it moves forward in the left-right direction by the maximum amount S.

The left and right edges of the relief 7L1b are provided in an arc shape at a position that does not impede this movement of the end plate 9.A notch 1C for taking out paper is provided on the front side edge of the storage bin bottom plate 1a. ing.

Further, as shown in FIG. 5, a front door 10 of the sorter is provided close to the front side of the storage bin, and the front side edge of the paper 6 discharged from the pair of discharge rollers 5 into the storage bin 1 is closed. The distance between S and the inner surface of the front door 10 is S', which is slightly smaller than S.
has been adjusted to be.

Since this device is constructed as described above, the paper 6 ejected from the ejection roller pair 5 comes into contact with the end plate 9 and moves forward while pushing it in the direction of travel, so that the paper 6 is delivered to the ejection roller pair. 5, the force in the advancing direction of the paper becomes only inertia, which gradually weakens due to frictional force and eventually stops.

Since the storage bin bottom plate 1a is tilted upward in the front, the engine plate 9 and the lever 8 rotate around the shaft 7 due to their own weight, and a force is constantly acting to push the paper 6 back.
The end plate 9 pushes back the paper 6 while moving in parallel along the front edge of the paper 6 until the rear end abuts against the rear end wall 1d of the storage bin.

At this time, the end plate 9 moves in an arc around the shaft 7 as shown in FIG. 6, so the friction between the end plate 9 and the front edge of the paper 6 causes the paper 6 to retreat and at the same time move forward a distance S. The front door 10 attempts to move as much as possible, comes into contact with the inner surface of the front door 10, and follows this pattern, thus aligning the front, rear, left, and right directions.

When the size of the paper changes, the position at which the leading edge of the paper settles after being pushed back by the end plate 9 differs, but as is clear from FIG. Since the position in the left and right direction hardly changes even if there is a large change, the side edges of the paper can be aligned with the inner surface of the front door, regardless of the size of the paper.

In addition, if a transparent material such as synthetic resin or glass is used for all or a required part of the front door, the sides of the sheets arranged on the storage bin will be in contact with the inner surface of the glass, etc. of the front door and overlapped. This makes it extremely convenient to visually check the storage status of the paper in the storage bin.

In addition, the opening and closing of the front door is linked with the drive power of the copying machine and sorter, so that the front door will not open unless the copying machine and sorter are turned off, and the power of the copying machine and sorter will not be turned on unless the front door is closed. By disabling the paper from entering the machine and making it inoperable, you can prevent malfunctions such as paper being ejected into the storage bin with the door open and falling out of the machine or being lost.

Further, the copying machine and the sorter may be automatically turned on and off by opening and closing the front door.

As described above, according to the present invention, the paper ejected into the storage bin can be aligned in the front, back, right, and left directions with a simple mechanism, regardless of the size of the paper, and without any effort at all, and the storage status can be visually checked. It is also convenient to take out sorted paper,
Effective in streamlining office work.
