BACKGROUND OF THE INVENTION
The present invention relates to a stacker that stores forms in a stacked state, and more particularly, to a stacker that includes a device that inserts a slip sheet between a form and a subsequent form in order to sort the stacked forms.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a stacker is used in which a single form on which predetermined information is printed is stored in a stacked state by successively supplying it onto a stacking table that is gradually lowered. In addition, when the forms are stacked in a stacked state on the stacking table, the forms that are continuously supplied are classified by the unit of the related forms (hereinafter referred to as name identification). Insert a narrow slip sheet between the last of the relevant forms to be stacked and the next form to be stacked on it, with at least one end extending outward from the edge of the form. Also known are those with an insertion device.
[0003]
[Problems to be solved by the invention]
However, in a stacker equipped with a conventional slip sheet insertion device, slip sheets are inserted at the same position of the stacked forms, and therefore, the slip sheet insertion portion of the stacked forms is raised by the accumulation of the slip sheet thickness. There was a problem that the form was unstable and easily collapsed. Further, since the slip sheet inserting device is one, if the slip sheet inserting device breaks down, the slip sheet cannot be inserted, and accordingly, the name collation function for separating the name collated form and the subsequent name collated form becomes impossible. There was also a problem.
[0004]
The present invention has been made in view of the above-described problems, and provides a stacker with a slip sheet insertion device that is less likely to collapse in a stacked form, even though the slips are stacked while inserting slip sheets. For the purpose. It is a second object of the present invention to provide a stacker with a slip sheet insertion device that hardly impairs the name identification function.
[0005]
[Means for Solving the Problems]
In order to solve the above-described problems, when inserting slip sheets between stacked forms, the slip sheets are selectively placed at positions shifted in the surface direction of the forms, and both ends of the slip sheets are in the form. It is configured to be inserted so as to extend to both sides . With this configuration, the positions where the slip sheets are inserted into the stacked forms are distributed in a plurality of places, and the bulge due to the insertion of the slip sheets is distributed in a plurality of places. , Individual excitement becomes smaller and forms are less likely to collapse. Here, as a mechanism for selectively inserting the slip sheet at a position shifted in the surface direction of the form, one slip sheet insertion device is used, and the slip sheet insertion device is moved each time the slip sheet is inserted. Although it is good also as a structure, it is preferable to set it as the structure provided with the some interleaving paper insertion apparatus arrange | positioned at a fixed position instead of this. When a plurality of slip sheet insertion devices are used, when one slip sheet insertion device fails, the slip sheet insertion can be performed by the remaining slip sheet insertion devices, so that the name identification function is not impaired.
[0006]

Reference numeral 20 denotes a reading device that reads the mark 4 printed on the continuous form 1, and the name identification information indicated by the mark 4 read by the reading device 20 is used for controlling the name identification unit and the slip sheet inserting device as will be described later. The
[0011]
Reference numeral 21 denotes a form supply unit that conveys the separated single form 1A and sends it to the downstream, and includes a plurality of conveying belts 22, presser rollers 23, and the like. A stacker unit 24 receives the form 1A sent from the form supply unit 21 and stores it in a stacked state. This stacker unit 24 once collects only the related forms 1A that are continuously discharged and collects the names. When the next form 1A is sent, the stacker unit 24 sends the previously-named forms downward. A name collating unit 25 that is separated from the subsequent form 1A, and a stacking unit 26 that is disposed below the name collating unit 25 and receives the form 1A discharged from the name collating unit 25 in a stacked state.
[0012]
As the name collation unit 25, a known configuration can be used as appropriate, but in this embodiment, a unit having a pair of spiral fans 28 having spirals symmetrical to each other and a stopper 29 is used. The name identification by the name identification unit 25 is performed as follows. That is, while the pair of spiral fans 28 is stopped in the state shown in FIGS. 6A and 6B, the forms 1A are successively sent and collected on the pair of spiral fans 28. Immediately after the last form to be collated is sent, a pair of spiral fans 28 are connected to each other based on information from the reading device 20 (see FIG. 1), as shown in FIGS. Rotate in the opposite direction. As a result, the previously-named form 1A is sent downward along the spiral of the spiral fan 28 and separated from the position where the subsequent form 1A ′ is stacked. The spiral fan 28 stops when it makes one rotation from the initial position, discharges the form 1A previously named, and enters the state shown in FIGS. 6A and 6B again. Thereafter, by repeating the same operation, the predetermined form 1A can be identified and discharged downward.
[0013]
1 to 4, the stacking unit 26 includes a stacking table 30 disposed at a position for receiving a form 1 </ b> A discharged downward from the name collating unit 25, and the stacking table 30 of the form 1 </ b> A stacked on the stacking table 30. As the form is stacked, it descends so that the top surface is kept at almost the same height.
[0014]
The stacker unit 24 further includes three slip sheet insertion devices 32. Each interleaf inserting device 32 pulls out the interleaving paper 33 set in the winding state, and separates the interleaving paper 33 fed out from the feeding roller 34 that feeds out the slip 1A accumulated on the stacking table 30. A cutter 35 and the like are provided. Accordingly, after the form 1A that has been collected from the name collation unit 25 is discharged onto the stacking table 30, the slip sheet 33 is sent out by the slip sheet insertion device 32, and then the form 1A that has been collated from the name collation unit 25 is discharged again. By repeating the above, it is possible to insert the slip sheet 33 between the identified forms. Here, the slip sheet 33 inserted between the forms 1A is inserted so that both ends of the slip sheet 33 extend to both sides of the form 1A . As can be understood from FIGS. 3 and 4, the three slip sheet inserting devices 32 insert the slip sheets 33 at positions separated in the width direction of the forms 1 </ b> A stacked on the stacking table 30. The slip sheet 33 is arranged so as to be inserted in a position shifted in the surface direction, and each is driven independently. Accordingly, by selectively operating the three slip sheet inserting devices 32, the slip sheet 33 can be selectively inserted at a position shifted in the surface direction of the form. In addition, although illustration is abbreviate | omitted, the control apparatus which controls the whole apparatus is provided, and the following operation | movement is controlled.
[0015]
Next, the operation of the stacker with a slip sheet insertion device having the above configuration will be described.
The pin tractor 10 pulls out the continuous form 1, the slitter 12 cuts off the margin portions on both sides thereof, and the form cutting unit 14 cuts the continuous form 1 into a single form 1 A and sends it out to the form supply unit 21. The reading device 20 reads the mark 4 of the continuous form 1 and outputs the name identification information of the single form 1A to a control device (not shown). The form supply unit 21 sequentially discharges the single form 1A to the name collation unit 25, and the name collation unit 25 accumulates the predetermined form 1A to be collated on the pair of spiral fans 28. When the last form 1A to be identified is discharged onto the pair of spiral fans 28, the control device determines the discharge timing based on information read by the reader 20, and rotates the pair of spiral fans 28 once. . As a result, the classified form 1A is sent downward and discharged onto the stacking table 30. Further, the subsequent form 1A is accumulated on the pair of spiral fans 28 and is collected.
[0016]
When the identified form 1A falls on the stacking table 30, the control device determines the timing, operates one slip sheet inserting device 32, and feeds the slip sheet 33 onto the form 1A on the stacking table 30. Thereafter, as the name collation at the name collation unit 25 ends, the pair of spiral fans 28 once again rotate, eject the collated form 1A, and stack it on the form 1A and the interleaf 33 on the stacking table 30. As a result, the slip sheet 33 is inserted between the name-named form and the next name-named form.
[0017]
Next, another slip sheet insertion device 32 is activated to feed slip sheets 33 onto the forms 1A that have been discharged and stacked on the stacking table 30. Thereafter, by repeating the same operation, the form cutting unit 14 separates the sheets into one form, and the forms 1A to be discharged one after another are collected by the name collation unit 25, stacked on the lower stacking table 30, and each collated form. Between 1A, the slip sheet 33 is sequentially inserted using the three slip sheet insertion devices 32. Thus, the stacking platform 30 on the integrated form 1A, the interleaf sheet 33 is inserted dispersed in three places, therefore, is raised by the slip sheet insertion rather small, yet, the interleaf sheet 33, both ends form Since it is inserted so as to extend to both sides of 1A, the swells in the front-rear direction of the accumulated forms 1A are also uniform, and the accumulated forms are not easily collapsed, and stable accumulation is performed.
[0018]
At the time of stacking as described above, the form cutting unit 14 and the downstream form supply unit 21 discharge the single form 1A one after another at a high speed, but the discharged form 1A is temporarily stored in the name collation unit 25. Since only the number of sheets to be identified is retained and then discharged to the stacking table 30, there is a considerable time until the next form 1A is discharged after the named document 1A is discharged to the stacking table 30. In this time, the slip sheet 33 may be inserted. For this reason, sufficient time is ensured for the insertion of the slip sheet 33, and the slip sheet is surely inserted.
[0019]
When one of the slip sheet inserting devices 32 fails, the remaining slip sheet inserting device 32 inserts slip sheets. As a result, the name identification function is not impaired.
[0020]
In the above embodiment, three slip sheet inserting devices 32 are arranged, but the number of slip sheet inserting devices 32 used is not limited to three, and may be two or four or more. The plurality of slip sheet inserting devices 32 are preferably disposed at positions that are symmetrical with respect to the center of the form 1A. With this configuration, it is possible to obtain an advantage that the forms 1A stacked while inserting the slip sheets 33 are stable and are not easily collapsed. Further, when arranging a plurality of slip sheet insertion device 32 it is not limited to the case of placing on one side all the interleaf insertion device 32 with respect to the stacking platform 30, as shown in FIG. 8, a slip sheet insertion device 32 It may be arranged on both sides of the stacking table 30.
[0021]
In any of the above-described embodiments, a plurality of slip sheet insertion devices 32 are provided at fixed positions, and the plurality of slip sheet insertion devices 32 are selectively operated to be shifted in the surface direction of the form. However, the present invention is not limited to this configuration, and a single slip-sheet inserting device is used and moved to shift the slip-sheet insertion position. Is also possible. That is, one slip sheet inserting device can be moved to a plurality of slip sheet insertion positions set in the surface direction of the form, and a slip sheet is inserted for each slip sheet insertion from the plurality of slip sheet insertion positions. It is also possible to select an insertion position, move the slip sheet insertion device to the selected slip sheet insertion position, and insert the slip sheet at a position shifted in the surface direction of the form. In this case, the mechanism for moving the slip sheet inserting device is arbitrary. For example, a guide is provided along the width direction of the form, the slip sheet inserting device is movably held in the guide, and further, along the guide. This can be easily realized by providing a moving device including a feed mechanism using a combination of a ball screw and a nut for moving the slip sheet inserting device and a motor for driving the ball screw.
[0022]
In the above embodiment, the stacker unit 24 includes the name identification unit 25. However, the name identification unit 25 is not necessarily required for the present invention, and the form supply unit 21 directly supplies the form to the accumulation unit 26 for accumulation. It is good also as a structure. Furthermore, in the above-described embodiment, the form cutting unit 14 for cutting continuous forms into single forms is provided upstream of the form supply unit 21, but the form cutting unit 14 is omitted, and a single form is obtained at another location. A form may be set in the form supply unit 21, and the form supply unit 21 may pull out and send it out one by one.
[0023]
【The invention's effect】
As described above, the stacker of the present invention stores the form supply unit that sequentially sends out forms, the reading device that reads the marks attached to the form, and the forms sent out from the form supply unit in a stacked state. And a slip sheet inserting device for inserting slip sheets according to the information of the reading device between the stacker portion and the slips stacked on the stacker portion, and the slip slip inserting device is shifted in the surface direction of the slip. Since slip sheets are selectively inserted into positions so that both ends of the slip sheets extend to both sides of the form, the slip is shifted in the face direction of the form between the forms stacked in the stacker unit. The slip sheet can be inserted at a certain position, and the rise due to the slip sheet inserted between the forms can be dispersed to prevent the form from collapsing, thereby enabling stable operation. .
[0024]
Here, by providing a plurality of slip sheet insertion devices so that slip sheets are inserted at positions shifted in the surface direction of the forms stacked on the stacker unit, one slip sheet insertion device fails. In this case, it is possible to insert the slip sheet with the remaining slip sheet inserting device, and therefore, the effect that the name identification function is not impaired can be obtained.
