Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper sorting machine for sorting cards and office documents.

A paper sheet in which a large number of pockets are arranged along a paper transport path from a paper hopper, a selection valve is provided corresponding to each pocket, and the paper is guided to a desired pocket by operating the selection valve. Classifiers are already in use.

This kind of sorting machine requires sorting a large amount of paper, so
High-speed processing is desired.

On the other hand, there is also a strong demand that the size of the classifier should not be too large. Also, if there is a need to sort more than the total number of pockets, or if all the sheets are to be rearranged in order according to their unique numbers, it may be necessary to run a group of sheets through the sorter multiple times.

In such a case, the question is what order the sheets in one pocket are loaded in the first classification.

SUMMARY OF THE INVENTION An object of the present invention is to provide a paper sorting machine that can satisfy the above-mentioned requirements.

In order to achieve the above object, the inventor of the present invention focused on the fact that the size of the sorting machine could be reduced to 4 mm by arranging the pockets in two stages, upper and lower, and solved various problems related to this. That is, the paper sorting machine according to the present invention is a paper sorting machine that sorts sequentially fed sheets into pockets arranged along a conveyance path, in which pockets are sequentially arranged in upper and lower pairs along the paper conveyance path. , a pair of rollers for conveyance and feeding provided in upper and lower pairs for each pair of pockets, and a pair of rollers for conveying and feeding provided in upper and lower pairs for each pair of pockets, and a pair of rollers provided corresponding to the roller pair, which can take a neutral position, an upper layer, and a lower path. each pocket has an inclination of more than 900 with respect to the sheet conveyance direction; When the selection valve is brought to a lower level, the paper is placed in the upper pocket by the upper guide of the selection valve, and when the paper is brought directly to the upper layer, the paper is lowered by the lower guide. It is configured to be guided into the side pocket.

According to the above configuration, the number of sorting valves is only half of the total number of pockets, and since the paper is stacked diagonally in each pocket so that the paper that was fed first is on the bottom, the paper The objects of the present invention can be fully achieved, such as being very convenient when sorting or when using the sorter in succession.

The classifier according to the present invention will be explained in more detail below with reference to the drawings and the like.

FIG. 1 is a perspective view showing an embodiment of a classifier according to the present invention.

In this embodiment, a large number of electromagnetic devices inside the sorting machine drive the sorting valves and sort them in response to signals from an external device (not shown). The electromagnetic device can also be configured to select a pocket by driving the electromagnetic device. In FIG. 1, D is a paper supply section, and the sheets stacked here are sequentially sent out to a conveyance path.

An upper pocket group B is arranged above this conveyance path, and a lower pocket group C is arranged below it. This pocket group is configured in an upper and lower pair, with the upper pocket maintaining an angle of Q, and the lower pocket maintaining an angle of Q2 with respect to the conveying direction A.

These angles Q, , Q2 are all larger than 900. Therefore, the paper sent later and stored in the pocket is stacked on top and bottom, and the front and back sides of the paper are made to match.

FIG. 2 is an explanatory diagram showing the concept of a classifier according to the present invention.

Paper is fed one by one from the right side in the figure by the upper roller a.
, lb, lc...1g, lower rollers 2a, 2b,...
It is sent to the left by a conveying means formed from each pair of 2g. A rotational force is applied to all of the lower rollers 2 from a drive source (not shown) so that they rotate clockwise. Each upper roller is rotated in contact with a lower roller 2 serving as a pair. Upper and lower pocket plates 3a and 4a are made to correspond to each o-la pair, for example la and lb, respectively.
The selection valve corresponding to each pair of rollers has an upper guide 6 and a lower guide 7, which can be moved up and down together.

When the selection valve is in the neutral position, the paper passes through the passage hole,
It is sent to the next pair of rollers. Passage ducts 8a, 8b, . . . , 8f are provided between the selection valves. The selection valve is a lever 5a driven by an electromagnetic device as described later.
・・・・・・It is moved up and down by rotation of 5g.

The selection valve with guides 6c, 7c is shown in a raised position. In this state, the paper sealed via 8b is guided by the lower guide portion 7c, dropped into the pocket space formed by the lower pocket plates 4c and 4b, and stacked on 4c.
When the sorting valve with guides 6f, 7f is brought into the upper and lower positions, the paper is thrown up into the space in the pocket between 3g, 3f and is loaded onto 3f. Although this figure shows the selection valve in the raised position and the selection valve in the lowered position for comparison, the two are not operated at the same time. Next, the relationship between the upper and lower rollers and the selection valve will be further explained.

FIG. 3 is a view of the roller pair from the direction in which paper is fed. The lower rollers 2 are provided with four lower roller shafts 10' each.

In this figure, only the two on the right side are shown. Lower roller shaft 1
0 is rotated in the paper feeding direction by a chain or the like (not shown). The upper rollers 1 are driven rollers, and two of them are fixed to the shaft 9.

The pair on the left side is omitted. The reason why four pairs of rollers are used at each location is to take into consideration that the widths of the sheets to be sorted are different, so that sheets with smaller widths can be transported by two pairs. Upper guide back plate 11,1
2 is fixed at both ends with a gap maintained, and an upper guide part 6 and a lower guide part 7 are fixed to each end.

The back plates 11 and 12 are fixed to the silk 13 together with the connecting spring 14.

The slider 13 is guided by a guide provided on the machine frame (not shown) and supports the selection valve so as to be able to move up and down with respect to the machine frame. The lower end of the connecting spring 14 is fixed to the tip of an upper and lower arm 15 that rotates together with a lever 5, which will be described later, about a shaft 20.

This rotation of the upper and lower arms 15 allows the selection valve assembly to be moved up and down. Next, the drive mechanism of the selection valve assembly will be explained in detail with reference to FIGS. 4 and 5.

The shaft 20 is a lever shaft fixed to the machine frame.

This lever shaft 201 is provided with the above-described upper and lower arms 15 and bar 5 such that they can rotate together. Grooves 5a and 5b are provided on both sides of the lever 5. A raising lever 1 is provided in the groove 5a so as to be rotatable around a fixed shaft 18.
The pin 16a that stands on the shield 6 is connected to the pin 16a.
A pin 17a that stands up against a lowering lever 17 that is rotatably provided around a fixed shaft 19 is coupled to the groove 5b. The raising lever 16 and the lowering lever 17 are attracted by a spring 21 extending between their lower ends, and the pins 16a and 17a of each lever hit the outermost ends of the grooves 5a and 5b of the lifting bar 5, and the lever 5 is moved. Keep it level. The inner arm of the lifting lever 16 is connected to a lifting electromagnet 24 via a lifting connecting rod 22.

Similarly, the inner arm of the lowering lever 17 is connected to the lowering connecting rod 23.
It is connected to the lowering electromagnet 25 via. In the state shown in FIG. 4, neither electromagnet is energized, and the lever 5 is kept horizontal by the force of the spring 21. The upper and lower arms 15 integrated with the lever 5 keep the selection valve assembly consisting of 6, 7, 11, 12, etc. in a neutral position via a connecting spring 14.

Therefore, in the state shown in FIG. 4, the paper supplied from the right is further sent to the left through the passage hole formed between the guide back plates 11 and 12. FIG. 5A shows a state in which the lever 5 is rotated clockwise by energizing the raising electromagnet.

When the raising electromagnet 24 (see FIG. 4) is activated, the raising connecting rod 22 is pulled down.

As a result, the raising lever 16 rotates counterclockwise about the shaft 18, and the pin 16a moves inward along the groove 5a, causing the lever 5 to move clockwise. At this time, the pin 19a of the lowering lever fits into the groove extending below the groove 5b, and the lever 5
Allow the left edge to rise. In this state, the upper and lower arms 15 (see FIG. 4), which rotate together with the lever 5, push up the connecting spring 14 and raise the selection valve assembly.

The positions 6c and 7c previously shown in FIG. 2 correspond to this state. In this state, the paper sent from the right side is guided by 7c and sent into the lower pocket. When the lifting electromagnet 24 is released, the lever 5 is moved by the force of the spring 21.
It returns to the horizontal position shown in FIG. FIG. 4 corresponds to this neutral state. When the lowering electromagnet 25 is energized, FIG.
As shown in , the lever 5 is moved clockwise and then stopped.

In this state, the selection valve assembly is in the lowered position (Fig. 2, 6f, 7f
position) and the paper is guided into the upper pocket. In FIG. 4, 26 is a detector provided for the purpose of detecting paper jams, so-called jams, and the like.

As described in detail above, the sorting machine according to the present invention can select three types of paper, upper, lower, and pass, by operating the same selection valve assembly.

The selection is possible with two electromagnets and no expensive electromagnetic equipment is required. When paper is guided to the upper or lower pocket, it is fed by the upper and lower rollers and rapidly changed direction by the guide section, and is thrown upward or downward, making it possible to reliably determine the direction and insert the paper.

Since the upper and lower pockets are oriented at an angle of more than 90 degrees with respect to the direction of travel, the sorted sheets loaded in each pocket can be stacked one on top of the other without distinguishing between the top and bottom for sorting or next sorting. Can be done.
