BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stacker in which forms are stored in a stacked state, and in particular, a separating slip sheet is inserted between a form and a subsequent form in order to separate the stacked forms. The present invention relates to a stacker equipped with a device.

[0002]

2. Description of the Related Art Heretofore, a stacker has been used in which forms on which predetermined information is printed are discharged one after another on a gradually descending stacking base to be stacked and stored. In addition, when the forms are stacked on the stacking table, the forms that are continuously discharged are divided into units of related forms (hereinafter referred to as “name identification”). It is also known that an interleaf sheet inserting device for inserting a narrow interleaf sheet such that at least one end of the interleaf sheet extends outward from the edge of the form is inserted between the item and the next form accumulated on the form. Has been.

[0003]

However, in the interleaf sheet inserting device in the conventional stacker, the next form falls after the last related form is ejected and stacked on the stacking table. To send interleaving paper in between,
Although it is necessary to send out the interleaving paper at a high speed at an extremely short time (for example, about 0.3 seconds), it is difficult to send out the interleaving paper at a high speed because the interleaving paper itself is not stiff. However, there was a problem that insertion errors were likely to occur.

The present invention has been made in view of the above conventional problems, and provides a stacker with an interleaving paper insertion device which can insert interleaving paper satisfactorily without lowering the processing capacity. The purpose is to

[0005]

In order to solve the above-mentioned problems, the present invention collects a plurality of related forms once in a name identification unit instead of directly discharging the forms sent to a stacker unit to a stacking unit. It is configured such that the name is sorted by name and then discharged to the stacking unit, and after sending the sorted form to the stacking unit and storing it in a stacked state, the slip sheet is sent in between the sending of the next sorted form. It is composed. According to the present invention, as described above, the name identification unit temporarily names a plurality of forms and then sends them out to the stacking unit to store them in a stacked state. Therefore, the time interval for discharging the forms from the name identification unit to the stacking unit becomes long. Therefore, it is possible to secure a sufficient time for inserting the interleaf sheet and to reliably insert the interleaf sheet.

BEST MODE FOR CARRYING OUT THE INVENTION A stacker of the present invention is a stack supply unit for sending out a form, a reading device for reading a mark attached to the form, and a stacker unit for storing the forms sent out from the form supply unit in a stacked state. And a stacking unit, in which the forms discharged from the form supply unit are accumulated based on information from the reading device, and a name identification unit that discharges after name identification, and is arranged on the discharge side of the name identification unit, A stacking unit that stores the sheets discharged from the name identification unit in a stacked state, and a sheet is discharged from the name identification unit and stored in the stacking unit after the name identification unit discharges the form and before the next sheet is discharged. It is characterized in that it has an interleaving paper inserting device for supplying interleaving paper between the form and the form which is next discharged from the name identification section.

According to the present invention, according to the above-mentioned structure, the related forms sent out one after another by the form supply unit are temporarily accumulated in the name identification unit, and after a predetermined number of names are identified, the forms are ejected to the accumulation unit and stored in a laminated state. The slip sheet insertion device sends the slip sheet to the front surface of the form, and then, the forms sorted by the name sorting unit are discharged to the stacking unit and stored in a stacked state, which can be repeated. It is possible to store the forms in a stacked state while inserting a slip sheet between the forms to be identified with. Here, since the time interval between discharging the form that has been sorted by the name collating unit to the stacking unit and discharging the next sorted form is longer depending on the number of collated sheets, it is possible to secure sufficient time for inserting slip sheets. , The interleaving paper can be inserted without sending it at a high speed as in the conventional case, and the interleaving paper is surely inserted.

It

Reference numeral 21 denotes a form supply unit that conveys and sends out the cut form 1A of a single form, and a plurality of conveyance belts 2
2 and a presser roller 23 are provided. 24 is a form supply unit 2
The stacker unit receives the forms 1A sent from the sheet 1 and stores them in a stacked state. The stacker unit 24 temporarily collects only the related forms 1A that are successively discharged and names them, and when the next form 1A is sent, the previously named forms can be sent downward. It has a name identification unit 25 which is separated from the following form 1A, and a stacking unit 26 which is arranged below the name identification unit 25 and receives and stores the forms 1A discharged from the name identification unit 25 in a stacked state.

As the name identification portion 25, a well-known structure can be appropriately used, but in the present embodiment, one having a pair of spiral fans 28 having spirals symmetrical to each other and a stopper 29 is used. There is. The name identification by the name identification unit 25 is performed as follows. That is,
While the pair of spiral fans 28 are stopped in the state shown in FIGS. 6A and 6B, the forms 1A are successively sent and accumulated on the pair of spiral fans 28,
Immediately after the last form to be sorted out is sent,
As shown in (a) and (b), the pair of spiral fans 28 is based on the information from the reading device 20 (see FIG. 1).
Rotate in opposite directions. As a result, the form 1A, which has been previously named, is sent downward along the spiral of the spiral fan 28, and is separated from the position where the following forms 1A 'are accumulated. The spiral fan 28 stops when it makes one revolution from the initial position, ejects the previously named form 1A downward, and enters the state shown in FIGS. 6A and 6B again. Hereinafter, by repeating the same operation, the predetermined form 1A can be identified and discharged downward.

1 to 4, the stacking section 26 has a stacking table 30 arranged at a position for receiving the form 1A discharged downward from the name collating section 25, and the stacking table 30 is stacked thereon. In order to keep the uppermost surface of the form 1A held at 1. at substantially the same height, the form 1A descends as the forms are stacked.

The stacker unit 24 further includes three interleaving paper inserting devices 32. Each interleaf sheet insertion device 32 draws out the interleaf sheet 33 set in the winding state and feeds it onto the form 1A accumulated on the accumulating table 30.
4 and a cutter 35 for separating the fed interleaving paper 33. Therefore, after the form 1A sorted by the name collating unit 25 is discharged onto the stacking table 30, the slip sheet 33 is sent out by the slip sheet inserting device 32, and then the name collating unit 2 again.
By repeating the operation of ejecting the form 1A sorted by name 5, the slip sheet 33 can be inserted between the sorted forms. Here, the interleaving paper 33 inserted between the forms 1A is inserted so that at least one end thereof extends from the edge of the form 1A, but the insertion depth is usually about half the length of the form 1A. Selected above. As can be seen from FIGS. 3 and 4, the three interleaving paper inserting devices 32 are arranged so as to insert interleaving paper 33 at positions apart from each other in the width direction of the forms 1A accumulated on the accumulating table 30. There is. Although not shown, a control device for controlling the entire device is provided and controls the following operations.

Next, the operation of the stacker with the slip-sheet inserting device having the above-mentioned structure will be described. The pin tractor 10 pulls out the continuous form 1, the slitter 12 separates the margins on both side edges thereof, and the form cutting unit 14 separates the continuous form 1 into a single form 1A and sends it to the form supply unit 21. Further, 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 identification unit 25, and the name identification unit 25 accumulates the predetermined forms 1A to be identified on a pair of spiral fans 28. Then, 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 the information read by the reading device 20, and rotates the pair of spiral fans 28 once. . As a result, the sorted form 1A is sent downward and discharged onto the stacking table 30. In addition, the following form 1A
Are collected on the pair of spiral fans 28 and are named.

When the sorted form 1A falls on the stacking table 30, the control device judges the timing, and one slip sheet inserting device 32 is operated to put the slip sheet 33 on the form 1A on the stacking table 30. Send in. After that, as the name identification unit 25 finishes the name identification, the pair of spiral fans 28 makes one revolution again, and the name-identified forms 1A are discharged and stacked on the forms 1A and the interleaf sheet 33 on the stacking table 30. As a result, the slip sheet 33 is inserted between the name-matched form and the next name-matched form.

Next, another slip sheet inserting device 32 is operated to feed the slip sheet 33 onto the sheets 1A discharged and accumulated on the stacking table 30. By repeating the same operation thereafter, the form cutting unit 14 separates the forms into one form, and the forms 1A discharged one after another are identified by the name identification unit 25, stacked on the lower stacking table 30, and each form identified. During 1A, the slip sheet 33 is sequentially inserted using the three slip sheet inserting devices 32. Thus, the slip sheets 33 are distributed and inserted in three places in the form 1A accumulated on the accumulating table 30, so that the swelling due to the insertion of the slip sheets is small, the accumulated forms are not easily broken, and stable accumulation is performed. Be seen.

At the time of stacking as described above, the form cutting unit 14 and the form supply unit 21 downstream thereof discharge the single form 1A one after another at a high speed, but the discharged form 1A is once sorted. The number of pieces that can be identified in part 25 is retained,
After that, since it is discharged to the stacking table 30, it takes a considerable time until the next form 1A is discharged after the sorted form 1A is discharged to the stacking table 30.
3 should be inserted. Therefore, a sufficient time is secured for inserting the slip sheet 33, and the slip sheet is surely inserted.

When one interleaf sheet inserting device 32 fails, interleaf sheets are inserted by the remaining interleaf sheet inserting devices 32. This does not impair the name identification function.

In the above embodiment, the interleaf paper inserting device 32 is used.
Although three are arranged, the number of interleaf paper inserting devices 32 used is not limited to three, and may be one or two or more. However, it is preferable to use a plurality of sheets, because it is possible to disperse the swelling due to the insertion of slip sheets into the stacked forms and prevent the forms from breaking easily. Further, in this case, the plurality of interleaf sheet inserting devices 32 may be arranged at positions symmetrical with respect to the center of the form 1A to stabilize the stacked forms,
It is preferable because it does not easily collapse. Further, when arranging the plurality of interleaf sheet insertion devices 32, not only when all the interleaf sheet insertion devices 32 are disposed on one side of the stacking table 30, the interleaf sheet insertion devices 32 are arranged as shown in FIG. It may be arranged on both sides of the stacking table 30. Further, in the above embodiment, FIG.
As shown in FIG. 3, the interleaving paper 33 is inserted by the interleaving paper inserting device 32 so that only one end extends from the edge of the form 1A.
As shown in FIG. 8, both ends of the slip sheet 33 may be inserted so as to extend to both sides of the form 1A. With this configuration, the swelling of the accumulated forms 1A in the front-rear direction becomes uniform, and there is an advantage that it is more difficult to collapse.

Further, in the above embodiment, the form cutting unit 14 for cutting the continuous form into a single form upstream of the form supply unit 21.
However, the form cutting unit 14 may be omitted, and a form that is a single form may be set in the form supply unit 21 at another location, and the form supply unit 21 may pull out the form one by one and send it out. Further, in the above-described embodiment, the layout relationship between the name identification unit 25 and the stacking unit 26 and the stacking direction of the forms are set to the upper and lower sides, but the present invention is not necessarily limited to this configuration, and, for example, the forms are stacked in the name identification unit. However, it may be configured to horizontally send it to the accumulating unit and store it.
