Description

[Detailed Description of the Invention] Technical Field This invention relates to a sorter that sorts or collates and stores copy paper or printed paper discharged from a copying machine or printer.

Prior Art In general, a sorter is equipped with a large number of bins (trays for storing copy paper, etc.), and automatically selects one of the bins to sequentially collect copy paper, etc. (hereinafter referred to as "paper") discharged from a copying machine, etc. It is designed to be stored.

In such a sorter, it is conceivable to attach a display board showing the bin number to the entrance of the bin in order to confirm which bin the paper is currently stored in, but it is difficult to confirm visually.

It is also conceivable to attach an LED near the bin number on the display board and turn it on when the paper is stored to facilitate visual confirmation, but this increases the cost.

Purpose This invention was made in view of the above points, and its purpose is to facilitate visual confirmation of the bin in which paper is being stored, without increasing the cost.

Structure: In order to achieve the above object, this invention is equipped with a large number of bins each having a bin cam attached to the tip extending outwardly, and in order to store paper in a predetermined bin, a corresponding bin is attached to the bin cam. In a sorter that has a mechanism that opens the bin inlet by sliding it along the paper conveyance direction, a bin number is displayed on the top surface of each bin cam at a position that is exposed when the corresponding bin slides. be.

Hereinafter, a specific explanation will be given based on one embodiment of this invention.

FIG. 1 is a perspective view showing the appearance and drive section of a sorter implementing this invention.

First, when the paper passes through an exit sensor (not shown) of a copier, printer, etc., the roller drive motor 1 starts rotating, and the rotation is transmitted to the exit roller 3 via the roller drive belt 2. Rotate in the direction of arrow A.

The rotation of the exit roller 3 is transmitted to the upper exit roller 3', and the upper exit roller 3' rotates in the direction of arrow B.

The paper conveyed into the sorter passes between paper guides 4, 4', is held between exit rollers 3, 3', is further conveyed, and is stored in a predetermined bin.

Further, the roller drive motor 1 stops rotating after a certain period of time after the paper reaches the paper sensor 5 provided immediately before the exit rollers 3, 3', and at the same time, the exit rollers 3, 3' also stop rotating.

Next, the bin moving mechanism will be explained with reference to FIG. 2.

First, the bin drive motor 6 is connected to a copying machine (not shown),
In response to a drive signal from a control unit of a printer or the like, it starts rotating in the direction of arrow C when moving to the upper bin, and in the direction of arrow D when moving to the lower bin.

The rotation is transmitted to the Geneva wheel shaft 9 via the timing pulley 7 and the timing belt 8, and the Geneva wheel shaft 9 and Geneva wheels 10, 10' fixed to both ends thereof rotate.

The shaft 3a of the exit roller 3 is cylindrical, and the Geneva wheel shaft 9 is passed through it, so the Geneva wheel shaft 9 and the Geneva wheel 10, regardless of the rotation of the exit rollers 3, 3', are rotated. 10' can be rotated.

When the Geneva wheels 10, 10' rotate, as shown in FIG.
One of the two grooves 11 formed 180 degrees apart at 0 and 10' engages with the bottle moving pin 12 to lift the bottle 15.

Also, as the Geneva wheels 10, 10' rotate, the wheel switch 14 is once turned on by the cam 13 fixed to the Geneva wheel 10', and when the Geneva wheel 10' and cam 13 rotate 180 degrees, the wheel switch 14 is turned off again. Therefore, the rotation of the bin drive motor 6 is stopped.

In this way, the Geneva wheels 10, 10' are 180
Each time the machine rotates, only one bin 15 is raised to open the entrance of the bin 15 to accommodate the paper conveyed by the exit rollers 3, 3'.

If the direction of rotation of the bin drive motor 6 is reversed, the rotation speed of the Geneva wheels 10, 10' will be 180 degrees.
Only one bin 15 can be lowered to open its inlet.

As shown in FIG. 1, a bottle cam 16 is mounted on both sides of the tip of each bottle 15, projecting outward, and a sticker 17 displaying a bottle number is affixed to the top surface of each bottle cam 16. .

Next, the operation of the embodiment configured as described above will be explained with reference to FIGS. 4 and 5.

As shown in Figure 4, a bin 1 for storing paper
5 is the second bin 15b, for example, the inlet of the first bin 15a is raised by the Geneva wheels 10, 10' as described above, and the bin cam 16
a slides in the paper conveying direction along the bin cam 16b, and the first bin 15a and the second bin 15b
The interval between is widened.

At this time, since the bins 15 other than the first and second bins 15a and 15b overlap, the sticker 17 displaying the bin number cannot be seen, but the label 17 displaying the bin number of the second bin 15b that stores paper The seal 17b is spaced apart from the bottle cam 16a of the first bottle 15a and is exposed at a shifted position as shown in FIG. 5, so that it can be easily visually confirmed.

In this way, in this sorter, the bin number display of the bin storing paper is displayed as each bin is moved, so there is no need to count the bins or turn on the LED. It is easy to visually check whether it is stored in the

In the above embodiment, an example was described in which the bottle is opened using a Geneva wheel, but it is also possible to open the bottle using a helical cam, a locking pawl, or the like.

Also, in the above example, the number of bins is 10.
Although the example of the type has been described, it can also be implemented with other types.

Effects As explained above, according to this invention, it becomes easy to visually check the bin in which paper is stored, and the cost does not increase.
