Description

[Detailed Description of the Invention] "Industrial field of application" The present invention relates to a form stacking device for stacking forms such as checks which are not uniform in size.

"Prior Art" As a device for accumulating forms such as checks which are not uniform in size, there is a device shown in Japanese Patent Publication No. 63-501148.

The apparatus is provided with a flexible band at the introduction position of the stack part, the flexible band is deformed by the tip of the form sent into the stack part, and the rear end of the accumulated form is sent by the deformed band. By evacuating by the rush area at the tip of the coming documents,
It is designed to prevent the forms from colliding with each other and the forms to be sent from being mistakenly stacked in the rear side of the existing stacking device.

[Problems to be solved by the device] However, when the number of forms accumulated in the device increases, the force with which the rear end of the forms presses the flexible band also increases. Even if the flexible band is deformed when the leading edge of the incoming forms plunges into the stack portion, the pressing force at the rear end of the already accumulated forms becomes larger than the urging force of the flexible band. For this reason, the trailing edge of the accumulated forms cannot be saved from the entry area at the leading edge of the conveyed forms, and the conveyed forms accidentally enter the rear of the accumulated forms and are read. When the forms are sorted in the order of data, the sort order is broken. In the worst case, the forms may collide with each other, causing a jam problem in the stack part, which may cause a problem that the subsequent mechanical processing of the forms becomes impossible. It was

Therefore, the object of the present invention is that the rear end of the accumulated forms cannot be retracted from the rush area of the leading end of the forms that are sent,
To solve the problem that the sent-in forms accidentally enter into the post-report of the already-collected forms or the forms collide with each other, and to perform the sorting process or the machine process smoothly after the accumulation. The purpose is to provide a form accumulation device capable of performing the above.

[Means for Solving the Problem] In order to achieve the above-mentioned object, the present invention has a stacking device for forms, which has a stacking part including a stacking region for stacking forms and a receiving region into which forms are sent. In the above, along the boundary between the stacking area and the receiving area, a plurality of scraping blades that move in the same direction as the form is fed are provided, and the plurality of scraping blades have a predetermined distance from each other. It is characterized in that it is provided so as to be inclined with respect to its moving direction.

[Operation] According to the present invention, the scraping blade is moved along the boundary between the stacking area and the receiving area in the same direction as the direction in which the documents are fed, and is inclined with respect to the moving direction. Since the leading edge of the scraping blade is forcedly scraped from the rear end toward the stacking area, the leading edges of the scraping blades are sent to the receiving area. When the scraping blade moves further, it is moved to the stacking area through the gap of the scraps and the documents scraped by the tip of the scraping blade. When the next form is sent to the receiving area after such scraping, the forms sent earlier are already scraped from the trailing edge by the scraping blade. The tip of the next form and the rear end of the form that has been sent will not be misaligned or collided. It should be noted that the scraping blades are arranged at a predetermined interval from each other and continuously move along the boundary between the stacking area and the receiving area of the stack portion, so that any position along the boundary can be set. You can scrape the forms with. As a result, even if the forms having different lengths are sequentially sent, the forms are always scraped in the order in which they are sent.

[Embodiment] A form accumulating apparatus according to a first embodiment of the present invention will be described with reference to FIGS.

As shown in FIG. 1, the stacking apparatus 1 according to the first embodiment has a stacking unit in which documents in a standing posture (a posture orthogonal to the paper surface in FIG. 1) are fed and the documents are accumulated in the posture as they are.
It has an endless belt 20 joined with a plurality of scraping blades 21 for scraping and separating the fed documents, and four pulleys 30 for winding the endless belt 20.

Here, the stack portion 10 is a plurality of endless belts (not shown).
It has a receiving port 11 that is connected to the transport path 90 configured by, for example, and that receives forms, a front face 12 and a side face 13 that are formed by a plate member, and the inside thereof has a receiving region 15 and a collecting region 16. It is divided into two areas. Of the side surface 13,
What is present in the receiving area 15 forms a convex surface 13a that projects into the stack.

In addition, the scraping blades 21 are provided with a predetermined interval so that documents can pass between the scraping blades.
The endless belt 20 passes through the boundary between the receiving area 15 and the stacking area 16 of the stack portion 10. In order to scrape the forms in the receiving area 15, the receiving area 15
It is provided in an appropriately inclined state so that an angle θ formed between the existing portion 21a and the moving direction (in the stack portion 10 in FIG. 1, the direction indicated by the white arrow) is an acute angle. In this case, the scraping blade 21 is joined to the endless belt 20 at its end 21b, as shown in FIG. Of the scraping blades 21, at least part of the scraping side 21
The c is formed of a flexible material such as plastic, and the other parts are formed of thin metal pieces or the like in order to have some strength.

In the stacking device 1 of the first embodiment having such a configuration, first, among the forms conveyed one by one by the conveyance path 90, the ones sorted by the sorting fork 40 are sent from the receiving port 11. As shown in FIG. 3 (A), it is put into the receiving area 15. Here, the stack part 10 has a convex surface 13
Because it has a, the rear part 50a of the form 50 has scraping blades.
It will turn to the 21st side. Since the scraping blades 21 continuously move downward in FIG. 3, the forms 50 are scraped at the rear end 50a, and the scraps 21 enter the gap 91 between the scraping blades. In this state, the next form 51 is sent from the receiving port 11 (FIG. 3 (B)).
When the scraping blade 21 moves further, the rear end 50 of the form 50
a will completely enter the integrated region 16 (FIG. 3 (C)). When the scraping blade 21 moves further, forms
The 50 completely passes through the gap 91 and moves into the stacking area 16 to complete the stacking, and the scraping blades go out of the stack section 10. Then, the trailing edge of the next form will be scraped off by the scraping blade, and thereafter the forms will be sequentially accumulated in the same manner. Since the scraping blades 21 are continuously moved at a predetermined interval, even if documents having different lengths are continuously fed, they are always scraped in the order in which they are fed.

Next, the form stacking device 2 of the second embodiment of the present invention is
This will be described with reference to FIGS.

As shown in FIGS. 4 and 5, the stacking device 2 of the second embodiment has a receiving area with respect to the stacking device 1 of the first embodiment.
The side surface of 65 is a flat surface 63a, and the receiving area 65 is narrowed so that the side portion 21d of the scraping blade 21 comes into contact with the flat surface 63a. The attitude of the forms handled in the second embodiment is the same as the attitude of the forms handled in the first embodiment.

In the stacking device 2 of the second embodiment having such a configuration, the forms 52 are first sent from the receiving port,
As mentioned above, the scraping vanes narrow the receiving area 65.
Since the side portion 21d of 21 comes into contact with the flat surface 63a, the one of the scraping blades 21 closest to the receiving port and the leading end of the form collide with each other (not shown). However, in the integrated device of the present invention, since the part 21c of the scraping blade 21 on the form-scraping side is made of a flexible material, the scraping blade 21 bends to form a document due to a collision. Problems such as deformation of the forms can be avoided, and the conveyance of the forms 52 is not hindered.

In this way, as shown in FIG. 6 (A), the forms 52
Are thrown into the receiving area 65. Since the scraping blade 21 continuously moves downward in FIG. 6, the form 52 is scraped off at the rear end 52a, and in this state, the next form 53 is fed from the receiving opening 61. This is the case (Fig. 6 (B)). In the second embodiment, the scraping blade 21 scrapes the forms 52 while contacting the flat surface 63a in the stack portion 60. For this reason, even if the rear end 52a of the form 52 is curled in a direction in which the rear end 52a curls back with respect to the scraping blade, the scraping blade 21 will surely scrape. As the scraping blade 21 moves further, forms 52
The rear end 52a completely enters the integrated region 66 (FIG. 6 (C)). When the scraping blade 21 moves further, the forms 52 completely move into the stacking area 66 and the stacking is completed. Then, the rear end of the next form will be scraped off by the scraping blade, and thereafter, the forms will be sequentially accumulated in the same manner. Note that, like the first embodiment, the scraping blades 21 continuously move at a predetermined interval, so that even if sheets of different lengths are continuously fed, the order in which they are always fed It will be scraped off.

Next, the form accumulating device 3 of the third embodiment of the present invention will be described.
It will be described with reference to the drawings.

As shown in FIG. 7, the integrated device 3 of the third embodiment is
The shape of the scraping blade is modified with respect to the stacking device 2 of the embodiment, and the posture of the forms to be handled is the first,
This is similar to the second embodiment. This is the plane 73 of the stack 70
A notch portion 73b extending in the same direction as the moving direction of the scraping blade 81 is formed in a, and the scraping blade corresponding to the notch portion 73b.
A protruding piece 81e protruding from the side surface is formed on a part of the side portion of 81. This projecting piece 81e makes it extremely difficult for the forms to escape when scraping, so that it is possible to more reliably scrape the forms from the stacking device of the first and second embodiments described above.

"Effect of Device" As described above in detail, the device for collecting forms of the present invention is
The inside has a stack part consisting of a stacking area for collecting forms and a receiving area for receiving forms.
Along the boundary between the stacking area and the receiving area, a plurality of scraping blades that move in the same direction as the forms are fed are provided, and the plurality of scraping blades have a predetermined distance from each other. It is provided so as to be inclined with respect to the moving direction.

Therefore, the leading edge of the scraping blade is forced to scrape the forms fed into the receiving area from the rear end toward the stacking area, and when the scraping blade moves further, The scraped documents will be moved to the stacking area through the gap between the scraping blades. And when the following forms are sent to the reception area after scraping like this,
The documents sent earlier have already been scraped from the rear end side by the scraping blades. Further, since the scraping blades are a plurality of blades arranged at a predetermined interval from each other and continuously move along the stacking area of the stack portion,
It is possible to scrape the forms at an arbitrary position along the boundary, so that even if the forms having different lengths are sequentially fed, they are always scraped in the order in which they are fed.

Therefore, it is possible to stack the forms while preventing the misalignment or collision between the leading end of the next sent forms and the rear end of the sent forms, and thus the sorting process or the machine process after the stacking. Can be done smoothly.
