Description

[Detailed explanation of the invention] Ryotsu Emperor's Fighting Malonization Invention is a processing device that manufactures a booklet with a prescribed number of pages from the paper, more details, the address that corresponds to the page basis in which the required matters are printed in advance. Single sheets such as bills, billing slips, receipts, transfer slips, notification slips, etc., or continuous sheets on which these single sheets are arranged consecutively, can be stored as is in the case of single sheets, or as pages in the case of continuous sheets. After cutting into units, the device separates each page to form a booklet, aligns them, and stitches them together. In particular, the device cuts single sheets or cut continuous sheets into a predetermined number of sheets corresponding to each page. The sectioning, stacking, and sending them out to align them is related to the device.

For example, in the case of continuous paper, as shown in FIG. The cut sheets 1a are fed into the pockets 3 of 2, and when the number of sheets 1a reaches a predetermined number constituting a booklet, the rotary drum 2 is rotated in the direction of the arrow 6 to feed a predetermined number of sheets 1a into the booklet. It is configured to be dropped onto a conveyor 4.

However, with this configuration, the paper 1a dances in the pocket 3 and jams occur, and since the paper 1a is dropped from a high position relative to the conveyor 4, the paper 1a is likely to be misaligned, making accurate sorting impossible. There was a drawback. This drawback is not unique to the continuous paper 1, and it goes without saying that the classification similarly exists in the case of single-cut paper as long as the configuration of the apparatus is the same.

In order to eliminate this drawback, pocket 3
In place of the rotating drum 2 having a rotary drum 2, an improved proposal adopts a structure using a rotating hawk (Japanese Patent Application Laid-Open No. 54-26131) or a structure using a pair of freely rotatable spiral blades (Japanese Patent Application Laid-Open No. 54-92418). is proposed.

However, even in each of the above-mentioned improvement plans, the structure of these sections is completely different from that of the horizontal conveyance means located before and after the device, and there is a Since the linkage is not carried out smoothly, especially when the paper is sorted, the paper becomes free when it is sent out from the device, because a predetermined number of sorted sheets are supported on their bottom side. This is because the chisel rotates the rotating hawk and spiral feathers, causing it to fall downward. therefore,
Although the falling position is lower and the distance is shorter, there is a risk that the paper may become misaligned due to the fall. Particularly, when the rotational speed of the rotary hawk or spiral blade is increased in order to increase the processing speed, the disadvantage that the sheets become irregular tends to become more pronounced.

In order to solve these drawbacks, conventionally, members such as guides and pressers have been installed to stabilize the paper, but if the size or quality of the paper changes, each of the above-mentioned members It is also necessary to make adjustments, which makes handling complicated and difficult to adjust to the optimum state depending on the processing situation.

It is an object of the present invention to provide a partitioning device in a paper processing device that eliminates these drawbacks.

A standby section in which cut sheets or continuous sheets cut into unit numbers for "r-counting" are fed by, for example, a belt or rollers, and stacked until a preset number of sheets is stacked and wait, and this standby section. When the number of sheets fed into the section reaches a predetermined number, the sheets are clamped from above and below and sent out from the standby section so as to be aligned. It is composed of

A predetermined number of sheets of paper stacked in the standby section are held from above and below and sent out to be aligned, so that during this sending operation, the sheets do not become free and are kept in the stacked state. It will remain as it is and will not become irregular.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 1 to 3 of the accompanying drawings.

This support member 28 is for supporting the rear end of the paper 10. Further, a stopper 29 is provided near each drive pulley 18.21 so as to be rotatable in the left and right directions in FIG.
The stopper 29 is normally in a vertical position, but when rotated, it becomes horizontal and is positioned above the upper belt 16 (see Figure 2).This stopper 29 comes into contact with the leading edge of the paper 10. This prevents the paper 10 from moving and also positions it. Near the idler pulley 26 side of the stopper 29, there is an elevating roller 30 that abuts the lower surface of the lower belt 17 and is movable up and down using a known a mechanism.
is provided. At the position corresponding to this elevating roller 30, there is a gap between the upper and lower belts 16, 17, but when the elevating roller 30 is raised, each belt 16, 17 has a contact distance of 4 km, and the paper 10 It is possible to hold the support member 2 (see Fig. 2).
The distance from the vertical portion of the sheet 8 to the stopper 29 corresponds to the vertical size of the sheet 10, and the distance can be easily adjusted according to this size by moving the movable plate 27 in the horizontal direction. .

Note that the paper 1 is removed in the gap between each idler pulley 20.24 and the stopper 29 on each of the upper and lower belts 16.17.
0 constitutes a standby section in which a predetermined number of sheets of paper 10 are stacked, and constitutes a delivery mechanism that grips the paper 10 from above and below in a conveying section between the elevating roller 30 and each drive pulley 18, 21 and sends it out from the standby section. The paper 10 is placed in the waiting section at the conveyance section between the pulley 22 and each idler pulley 20°24.
This constitutes an infeed structure that sends in m.

In addition, each drive pulley 1 of the above-mentioned upper and lower bells) 16 and 17

In this way, when a predetermined number of sheets lO, which have been set for tightening, are fed into the standby section, as shown in FIG. The tip of the paper LO is at the top and bottom bells) 16
．． 17 from above and below. Subsequently, the stopper 29 is displaced to the water droplet state, and the paper 10 is sorted by the device 11 while being held between the belts 16 and 17.
from there onto the transfer conveyor 39. Thereafter, the jogger part 33 and the stitcher part 34 align the sheets of paper IO and stitch them together to create a booklet.

On the other hand, when the paper 10 is sent to the transfer conveyor 32,
The stopper 29 returns to the vertical state again before the next sheet 1o is fed into the waiting section, and the elevating roller 30 descends to again form a gap between the upper and lower belts 16, 17 in preparation for the next operation.

In this way, the classification in this embodiment is such that the paper 10 is
Since they are always clamped from above and below, there is no risk of jams or irregularities caused by dancing in the standby section.

Next, a second embodiment of the present invention applied to continuous paper will be explained based on FIG. W12
The two divisions from a are equipped with devices. Each of these sections is a device 12b.

12a is each driven pulley 19b, 19a, 22b, 2
2b, the section of the first embodiment has the same configuration as the device 11, with the upper section having the same components as the device 11.
For the lower section vi1l2a, the corresponding components of the first embodiment are shown with the same reference numerals as the device 11 with a subscript a added thereto. Also,
Other components having the same configuration are shown with the same reference numerals.

As in the first embodiment, the paper 10 cut into a predetermined number of sheets by a part of a known datarature (not shown) is supplied to a carry-in bell (13), and is rotated vertically on a shaft as shown in FIG. The portion having a rectangular side surface supported by 35 is conveyed toward member 36.

When the member 36 rotates clockwise in FIG. 3, the sheet 10 is folded downward and the lower section is fed into the device 12a, while when the member 36 rotates counterclockwise, the lower section is fed into the device 12a. , the paper 10 is guided upwards and the upper section is connected to the device! 1
2b.

As previously mentioned, the upper section is device 12b and the lower section is device 1.
2a, the first embodiment is divided into device 11
Since they are basically the same, their explanation will be omitted, and the configuration of the conveyance path from the devices 12a, 12b to the transfer conveyor 32 will be explained for each section.

The upper section is from the device 12b to the upper and lower bells) 16b.

The paper lO sent out by the drive pulley 18b
and the belt 38 that is passed between the drive pulley 21b and the driven pulley 37, the belt 40 that is passed between the drive pulley 21b and the driven pulley 39, and the drive pulley 21a and the driven pulley 41.
．． 42 and a conveyor belt 43 passed therebetween, the conveyor 32 is placed on a transfer conveyor 32 equipped with a feed pawl 31, one end of which is located directly below the driven pulley 41. It is configured to be transported. On the other hand, in the lower section, the paper 10 sent out from the device 12a by upper and lower belts 16a and 17a is composed of a belt 45 passed between a driving pulley 18a and a driven pulley 44, and the belt 43 and the belt 38. It is configured such that it is conveyed onto the transfer conveyor 32 while being held between the upper and lower directions by a conveyor belt.

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

In addition, the difference between this embodiment and the first embodiment in terms of operation is that the upper and lower sections of the paper 10 are supplied to the devices 12b and 12a, and the sections are carried out from the devices 12b and 12a to the transfer conveyor 32. It is. That is, paper 1
0 is distributed from the carry-in belt 13 by the member 36 and alternately supplied to the upper section to the device 12b and the lower section to the device ff12a, and each section is supplied to the device r! 112b and 12a are respectively divided into sections in the same manner as in the first embodiment, and then these sections are alternately held and sent out from the apparatuses 12b and 12a from above and below, and are then conveyed by the respective delivery belts configured as described above. , and is conveyed to the transfer conveyor 32 while being held between the top and bottom.

Therefore, in this embodiment, the paper 10 is always held between the top and bottom, not only when it is fed into and out of the waiting section, but also when it is transported onto the transfer conveyor 32. Therefore, there is no risk of jamming or misalignment in the standby section, and it is possible to maintain the stacked state in the standby section and convey it onto the transfer conveyor 32 without causing misalignment.

Further, as in this embodiment, the two sections are the devices 12b and 12.
By providing the section a, each section can be processed alternately by the devices 12b and 12a, which has the advantage of increasing the conveyance speed of the sheet 10 (same as a cut sheet) and further improving the processing speed. . Furthermore, if a plurality of sorting devices are provided as in this embodiment, each sorting device can also perform a function of distributing a predetermined number of sheets sorted by the device to different locations. - Note that the present invention is not limited to the embodiments described above; for example, the paper may be continuous paper or cut paper, and the feeding mechanism and the feeding mechanism may be configured with belts that are driven separately. In this case, it is also possible to omit the upper belt of the feeding mechanism, or to use the carry-in belt 13 as the feeding mechanism.Furthermore, the feeding mechanism may be configured with rollers instead of the belt. Many modifications are possible.

Summer - As is clear from the above explanation, according to the present invention, a predetermined number of stacked sheets are pinched from above and below and sent out from the device for sorting, which reduces the jam occurrence rate in the device. This has the advantageous effect of increasing the effective speed of the processing operation, preventing sheets from being misaligned during feeding, and improving the stability of the alignment operation.
