Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing apparatus for producing a booklet having a predetermined number of pages from a paper, and more specifically, an address card corresponding to each page, in which requirements are printed in advance. Single-cut sheets such as billing slips, receipt slips, transfer slips, and notification slips, or continuous papers in which these individual cuts are arranged in series are as they are in the case of single-cut papers, for example, in page units in the case of continuous papers. After cutting into sheets, the booklet is divided into pages to be composed, and the apparatus is arranged to butt and sew together, and in particular, cut sheets or cut continuous sheets are divided into a predetermined number of sheets corresponding to each page. The present invention relates to a sorting device that stacks the sheets and sends them to align them.

2. Description of the Related Art A general sorting device of this type in the related art is, for example, in the case of continuous paper, as shown in FIG.
Is fed into the pocket 3 of the rotary drum 2 for each page, and the cut paper 1a is fed into the pocket 3 of the rotary drum 2. When the paper 1a reaches a predetermined number of sheets forming a booklet, the rotary drum 2 is rotated in the direction of arrow A. The predetermined number of sheets of paper 1a are dropped onto the conveyor 4 having the feed claws 5.

However, according to this configuration, in addition to the paper 1a dancing in the pocket 3 and causing a jam, the paper 1a is dropped from a high position with respect to the conveyor 4, so that the paper 1a is likely to be misaligned and cannot be accurately sorted. There was a flaw. This drawback is not peculiar to the continuous paper 1 and, of course, also exists in the case of single-cut paper if the configuration of the sorting device is the same.

In order to eliminate this drawback, the pocket 3 has been conventionally used.
In place of the rotary drum 2 having a rotary drum, a configuration using a rotary fork (Japanese Patent Laid-Open No. 54-26131) or a pair using a pair of rotatable spiral blades (Japanese Patent Laid-Open No. 54-92418).
No.) has been proposed.

Problems to be Solved by the Invention However, even in each of the above-mentioned improvement plans, these sorting devices are completely different in configuration from the horizontal conveying means located in the front and rear thereof, and are different from those in the front and rear conveying means. Since the connection is not smoothly performed, the sheets are in a free state especially when the sheets are sent from the sorting device. This is because a predetermined number of divided sheets are dropped by rotating the rotary hawk and the spiral blade only by supporting the lowermost surface thereof. Therefore,
Although the drop position is lowered and the distance is shortened, there is a possibility that the paper may be misaligned due to the drop. In particular, when the rotation speed of the rotary hawk or the spiral blade is increased to increase the processing speed, the defect that the paper becomes uneven tends to be more remarkable.

In order to solve such a drawback, conventionally, a member such as a guide or a press is provided to stabilize the paper. However, when the size or quality of the paper is changed, each member is Since it is also necessary to adjust, the handling is complicated and it is difficult to adjust to the optimum state according to the processing situation.

SUMMARY OF THE INVENTION The present invention is directed to a sheet processing apparatus that prevents unevenness of sheets at the time of delivery from a sorting apparatus, particularly when the processing speed is increased, and does not require any adjustment in response to changes in sheet quality. The purpose is to provide a sorting device.

Means for Solving Problems Paper transporting means in which belt moving bodies which are supported by rollers or the like and circulate and move in a front and rear direction in a transport direction are vertically opposed to each other,
The upper belt moving body side of the lower belt moving body of the paper transfer means is detoured in a Z-shape by a rotating roller arranged with a vertical step and separated from the upper belt moving body to form a single sheet or Standby means constituted by a part of the paper transfer means for feeding continuous paper cut into a unit number of sheets to the paper transfer means, and stacking and waiting until a preset number of sheets, and this standby means When the number of the sheets sent to the printer reaches a preset number, they are sandwiched in the vertical direction and sent out so as to be aligned with each other from the standby means. For example, the feeding means constituted by a part of the paper feeding means and the rotary roller are integrated. The sorting device is composed of moving means for moving the sheet in the direction parallel to the sheet transfer direction.

A predetermined number of sheets of paper stacked in the work standby means are sandwiched in the vertical direction and sent out so as to be aligned with each other.Therefore, during this sending operation, the sheets are kept in the stacked state without becoming free. Keep it and never rumble. Further, even if the paper quality is changed, no adjustment is required correspondingly, and even if the size of the paper is changed, it can be easily dealt with by simple adjustment.

It is configured to be carried out on the transfer conveyor 32 provided with. On the other hand, the sheet 10 sent out from the lower sorting device 12a by the upper and lower belts 16a and 17a is the belt 4 wound around the drive pulley 18a and the driven pulley 44.
5 and the carry-out belt composed of the belt 43 and the belt 38, the carry-out belt is carried out on the transfer conveyor 32 while being held in the vertical direction.

Although not shown, a known jogger section and stitcher section are also provided on the transfer path of the transfer conveyor 32 as in the first embodiment.

The operation of this embodiment is different from that of the first embodiment in the supply operation of the upper and lower sorting devices 12b and 12b of the sheet 10 and the discharging operation from the sorting devices 12b and 12a to the transfer conveyor 32. . That is, paper 1
0 is alternately supplied from the carry-in belt 13 to the upper sorting device 12b and the lower sorting device 12a by the sorting member 36, and sorted by the sorting devices 12b and 12a in the same manner as in the first embodiment. The sorting devices 12b and 12a are alternately sandwiched and sent out from the vertical direction, and are conveyed to the transfer conveyor 32 while being sandwiched from the vertical direction by the carry-out belts configured as described above. .

Therefore, in this embodiment, the paper 10 is always held in the vertical direction not only when the paper 10 is fed into the waiting means and when it is sent out from the waiting means, but also when the paper 10 is conveyed on the transfer conveyor 32. Therefore, there is no risk of jamming or irregularity in the standby means, and the stacked state in the standby means can be maintained as it is and conveyed on the transfer conveyor 32 without irregularity.

Further, as in the present embodiment, the two sorting devices 12b, 12 are
When a is provided, since the sorting devices 12b and 12a can perform the sorting process alternately, it is possible to increase the transport speed of the sheet 10 (similarly to the single-cut sheet), and there is an advantage that the processing speed is further improved. Further, if a plurality of sorting devices are provided as in the present embodiment, it is possible to achieve a sorting function of distributing a predetermined number of sheets sorted by each sorting device to different places.

It should be noted that the present invention is not limited to the above-described embodiment, and for example, the paper may be continuous paper or single-cut paper,
Further, the sheet transporting means and the feeding means may be constituted by separately driven belts, and the feeding means may be constituted by rollers instead of the belt, and many modifications are possible.

Effect As is apparent from the above description, according to the present invention, a predetermined number of sheets of paper are sandwiched in the vertical direction and sent out from the sorting device, so the jam occurrence rate in the sorting device decreases and the processing is performed. It can increase the effective speed of work, and even if the paper quality changes, it does not require any adjustments, and it does not hinder the operation of each belt, and it is arranged with a step up and down to rotate it. Since the rollers can be moved integrally, it is easy to adapt to the size of the paper by supporting the trailing edge of the paper, and the misalignment of the paper at the time of delivery is prevented, and the stability of the butt alignment work It is possible to achieve the excellent effect that the above can be improved.
