Description

[Detailed description of the invention] The present invention is based on the invention, for example, by cutting out individual sheets from writing paper such as cards, booklets, slips, etc., or from continuous sheets of various formats made of written paper and stacking them in desired numbers. The classification relates to a conveyance width alignment adjustment device for a plurality of divided sheets of paper, which is configured so that the document feed width can be easily variably adjusted in accordance with the width of the object to be processed through the above processing in the processing device. be.

Generally, when stacking multiple sheets of paper such as billing slips, receipt slips, transfer slips, notification sheets, cards, booklets, etc. in predetermined numbers and binding them into one book, the individual sheets to be bound are combined into one continuous sheet. The sheets are separated from the perforations, stacked one after another in a desired number, and divided into sections, and then, in the process of sending the sheets to the binding section, the divisions are regulated by an alignment guide plate in the feed width direction.

However, it is desirable for the classification to be able to carry and align paper of many types and widths with the same aligner, but normally, for this classification, paper conveyance mechanisms are arranged in parallel at appropriate intervals. The chain has feeding claws protruding from it at regular intervals, so the maximum width section of the applicable conveyance width is the conveyance mechanism that can feed the paper, and the minimum width section is the so-called unnecessary chain when feeding the paper. Some parts will come naturally.

However, it is extremely difficult and inconvenient to remove the unnecessary chain portions and to remove the protruding feeding claws of the unnecessary portions each time the conveyance width range is changed.

In view of the above, the present invention can appropriately solve such inconveniences, and can simultaneously align multiple sheets of divided sheets in the conveyance direction and in a direction perpendicular to the conveying force, as well as align them in the direction perpendicular to the conveyance direction. We have developed an alignment adjustment device that makes width adjustment extremely easy.
Next, this will be explained with reference to the illustrated embodiment.

1, the section facing the paper feed mechanism side is section, and this section is section 1.
The classification of the predetermined number of sheets received in the pocket is paper a.
The division is transferred from the unit 1 to the transport mechanism 2 side.

The conveyance mechanism 2 includes a chain 4 with a feed pawl, in which feed pawls 3 are protruded at regular intervals, and is supported upright by a spring on the chain so as to be rotatable and descendable.
A table 5 which is arranged at a height such that only the feed claws protrude between the chains with feed claws, which are formed by arranging an appropriate number of chains in parallel.
The feed claw chain 4 has no sections so that it can move intermittently in the direction of the arrow in synchronization with the rotation of the part 1.

On the other hand, the section is provided with a guide 6.7 in a peripheral area on the conveying mechanism 2 side close to the section 1 for guiding the section in a direction orthogonal to the conveying direction of the sheet a in a butt-aligned manner.
The bottom plates 6a and 7a are placed on the surface of the table 5 and can be mounted and fixed by a mounting position adjustment device extending onto the chain 4 in a direction perpendicular to the conveying direction.

Therefore, in order to transfer the form a to the guide 6.7 side without erroneously conveying the form a from section 1, the section is divided into sections where the upper surface position of the table 5' is located on the table 5 surface. The bottom plate 6a, ? It is set to be slightly higher than the upper surface position of a.

In addition, the height relationship of the table 5' surface in the above section is such that the sheet portion of paper a does not enter between the table 5 and the bottom plates 6a and 7a or get caught on the edge of this bottom plate in the sections starting from section 1. As long as it is a mechanism, both table surfaces may be on the same surface, or the tips of the bottom plates 6a and 7a may be inclined downward like a knife, and the tip portions may be recessed into the table side.

In the above, the guide 6 is located on the side of the binding section 8, so that one side of the sheets a can always be aligned and guided to the predetermined binding position of this binding section, and the guide 7 is placed on the section side of the section. The bottom plate 7a of the waist guide 7 is wide and has a shape that is close to the guide 6 side and parallel to it in the conveyance direction.
has a relatively wide structure so that the spacing between the pair of guides 6 and the pair of guides 6 can be easily adjusted, and the bottom plate 7a is placed on the chain 4 with the feed claw along the guide 7 side within the range where the guide 7 is moved toward the pair of guides 6. There is no structure that allows it to be placed under cover.

The adjustment mechanism in the above does not include the fixing and adjustment of the guide 7 using the screw 9 for fixing the guide 7 and the screw hole 10 provided on the device body side for tightening the screw 9 when adjusting the position of the guide 1. It may also be a mechanism.

In this way, the feed pawl 3 is attached to the chain 4 with a feed pawl by pivoting the feed pawl 3 to the pin 4a as shown in FIGS. As shown in FIG. 4, it is erected so that it can be rotated and lowered in the opposite direction to the conveyance direction, and this erecting can be restricted by a claw stopper 3' engaging one of the pins 4'.

In the above, the structure of the feed claw 3 is such that the paper a can be conveyed in a pressure manner, and when it collides with the bottom plate 7a of the guide 7, the feed claw 3 passes through the bottom plate 7a (r). A configuration other than that illustrated may be used.

The apparatus of the present invention is constructed as described above, and the section 1 is for sorting, and the section for transfer to the conveying mechanism 2 after sorting is paper A, which is conveyed under pressure by a feed pawl 3 protruding from a chain 4 with a feed pawl. The guide 6.7 in the rain area performs alignment in the left and right width direction while also aligning the front and back.

Reference numeral 12 denotes a brush that assists in alignment in the front-back direction.

By the way, on the one guide 7 side, the bottom plate 7a can be placed on the chain 4 in the outer area that deviates from the alignment width when the chain 4 is moved inward according to the alignment width adjustment range as the guide 7 adjusts. When the butting width is narrowed with this bottom plate 7a, the unused feed pawl 3 automatically descends and moves while the feed pawl 3 is in progress in the butting section with the lowering permission of the feed pawl 3, so that the butting width is narrowed. There is no need for any means for removing the feeding claws of unnecessary chains due to downsizing.

Therefore, according to the present invention, the mechanism and handling operations are extremely simple, and the width dimension of paper a can be adjusted across the chain 4, and the range of adjustment can be widened. The use of a single machine for classification increases the versatility of processing and has great practical effects.
