Abstract

PURPOSE: To lessen occurrence of jamming as well as to make the divided position reliably distinguishable by certainly restraining continuous paper sheets from making an inclined condition due to sliding in the cross direction in the course of folding operation of continuous paper sheets. CONSTITUTION: Continuous forms 3 are folded in zigzag and stacked up on a stacker table 5 by beaters 4a, 4c, which are adjustable so that they can correspond with the folding width of the continuous forms 3, and the cross direction of the continuous forms 3 are prevented from sliding to the cross direction during folding operation by guiding them with stoppers 7a, 7b. Continuous forms 3 are demarcated by specific demarcation units and stacked up on the stacker table 5 by sliding the stacking position of the continuous forms 3 to the cross direction by means of displacing the position of the stacker table 5 to the cross direction of the continuous forms 3 by a displacement position means 6.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to FIGS. Here, FIG. 1 is a schematic front view of the folding and sorting apparatus, FIG. 2 is a side view of the same, FIG. 3 is a flowchart showing the operation of a stopper as guide means, and FIGS. 4A to 4G are explanations of the operation of the stopper. It is a figure.

As shown in FIGS. 1 and 2, the folding and sorting device 1 is a swing fin 2 swinging in the left-right direction in FIG. 2 and is a continuous sheet 3 having transfer holes on both sides in the width direction.
Fold in a zigzag shape at the perforations that form the unit sheet.
The folding end is folded by two pairs of rotatable beaters 4a, 4b and 4c (only one of which is shown for the pair) serving as folding means and stacked on the stacker table 5. A pair of the beaters 4a, 4b and 4c is configured to be movable in the contact and separation directions with each other, and is adjustable so as to correspond to the folding width of the continuous paper 3.

Further, the stacker table 5 is provided for the continuous paper 3
Is configured so that the folding end of the continuous paper 3 is located at the same height position as the folding operation of (1), and the width of the continuous paper 3 is changed by the position displacing means 6 including a conventionally known drive mechanism and drive force transmission mechanism. The position is displaceable in the direction. Further, two pairs of stoppers 7a, 7b, and 7c (only one of which is shown for a pair) are provided on both sides in the width direction of the continuous paper 3 as guide means for guiding the width of the continuous paper during the folding operation. Stoppers 7a, 7b and 7c are actuators 8a, 8
It is configured to be displaceable in the contact and separation directions with each other by b and 8c.

For convenience of explanation, the displacement positions of the respective stoppers 7a, 7b and 7c are located at the inner side of the end of the continuous paper 3 which was previously sorted and stacked below (hereinafter simply referred to as the inner end). Is the ON position (position of the stopper 7b in FIG. 1), on the contrary, the end located outside the end of the continuous paper 3 previously sorted and stacked below (hereinafter simply referred to as the outer end). The position where the outer edge can be pressed is the OFF position, and the position that is outside the OFF position and cannot contact the outer end is the separated position (stopper 7a in FIG. 1).
Position). That is, the inside broken line positions in FIG. 4 are ON positions, and the outside broken line positions are OFF.
These positions are relative positions that change depending on the position of the stacker table 5 and the stacking position of the continuous paper 3.

Next, the sorting operation in the state of FIG. 1 of this embodiment will be described with reference to FIGS. 3 and 4. Here, a case will be described in which the sorting operation of the continuous paper 3 is completed in the state of FIG. 4A, the folding position is changed to the position shifted to the left side in FIG. 4, and a new sorting operation is started. The continuous paper 3 is folded at the perforations by swinging of the swing fins 2, folded by the beaters 4a, 4b and 4c and stacked on the stacker table 5, but a predetermined number of folding operations to be sorted are performed. When the folding is detected by a folding counter (not shown), the continuous paper 3 is cut at a predetermined perforation (step 10).
1) On the other hand, the folding counter is reset and the count value returns to 0 (step 102).

When the cut ends of the continuous paper 3 are stacked on the stacker table 5, two pairs of stoppers 7a, 7a,
One of the stoppers 7a and 7c of 7b and 7c is O
If it is at the N position (step 103, FIG. 4A), the process proceeds to step 105. At this time, the other stopper 7b is OF
Since it is in the F position (FIG. 4 (A)), the actuator 8b
Is moved to and separated to the separated position (steps 103 and 104, FIG. 4B). In step 105, the position displacement means 6 is driven and the stacker table 5 is moved to the position shown in FIG.
When the stopper 7b is moved in the upper right direction (FIG. 4 (C)), the stopper 7b is relatively displaced to the OFF position (FIG. 4 (C)), while the stoppers 7a and 7c are also relatively O.
It will be displaced to the FF position (FIG. 4 (C)).

As a result, the folding operation of the new continuous paper 3 is performed at the position displaced to the left side in FIG. 4, and the stacking position is displaced to perform the sorting (FIG. 4).
(D)). When the folding counter (not shown) detects that a predetermined number of folding operations have been performed as the folding operation continues (step 106), each stopper 7 is pressed.
It is determined whether a, 7b and 7c need to be displaced to the ON position. One of these stoppers 7a and 7c is OFF
Since it is in the position (FIG. 4 (C)) and is in a position where the outer edge of the continuous paper 3 can be pressed (see FIG. 4 (D)), the displacement to the ON position is unnecessary and the process proceeds to step 109.

On the other hand, the stopper 7b on the other side is also in the OFF position (FIG. 4C), but this OFF position is the continuous paper 3
Since it is a position where the inner end of the can not be pressed (Fig. 4 (D))
(See FIG. 4D), after moving to step 108 and being moved to the ON position by the actuator 8b (see FIG. 4D).
Move to step 109. Then, each stopper 7a, 7b
And 7c, the folding operation is continued in the state of FIG.

Then, when the folding counter (not shown) detects again that the predetermined number of folding operations have been performed, the continuous paper 3 is cut at the predetermined perforations (step 101). On the other hand, the folding counter is reset and the count value returns to 0 (step 102). Here, when the cut ends of the continuous paper 3 are stacked on the stacker table 5, the stoppers 7a and 7c on one side of the two pairs of stoppers 7a, 7b and 7c are in the OFF position contrary to the above. (FIG. 4 (E)), the actuators 8a, 8c have moved the actuators 8a, 8c to the separated positions (steps 103, 104, FIG. 4 (F)).
Then, it moves to step 105. At this time, the other stopper 7
Since b is in the ON position (step 103, FIG. 4E), the process proceeds to step 105 without displacement.

Then, in step 105, the position displacement means 6
Is driven, and the stacker table 5 is moved leftward in FIG. 4 contrary to the above (FIG. 4 (G)). By moving the stacker table 5 leftward in FIG. 4, the stoppers 7a and 7c are relatively displaced to the OFF position, and the stopper 7b is also relatively displaced to the OFF position (FIG. 4). (G)). As a result, the new folding operation of the continuous paper 3 is performed at the position shifted to the right side in FIG. 4, the sorting is performed, and the folding operation is continued. Then, the folding counter (not shown) detects that a predetermined number of folding operations have been performed (step 1).
06), and again, the stoppers 7a, 7b and 7c become O
It is determined whether displacement to the N position is necessary.

Here, since the stoppers 7a and 7c on one side are in the OFF position and are in positions where the inner edge of the continuous paper 3 cannot be pressed (see FIG. 4G and FIG. 4C). , Move to step 108, and each actuator 8a,
After being moved by 8c and displaced to the ON position, the process proceeds to step 109. On the other hand, since the stopper 7b on the other side is in the OFF position and is in a position where the outer edge of the continuous paper 3 can be pressed (see FIG. 4G and FIG. 4C), the process proceeds to step 109. In this way, the folding operation is continued again, and the operations from step 101 to step 109 described above are performed for the continuous paper 3 of a predetermined amount.
It is repeated until the folding operation for is completed.

The present invention is not limited to the above-described embodiment, and the stacker table 5 is not lowered as the continuous paper 3 is folded, but the swing fins 2, beaters 4a, 4b, 4c, stoppers 7a, 7b, 7c may be configured to rise. Further, the folding means is not limited to the beaters 4a, 4b, 4c, and the folding end may be pressed by a plate member such as a pressing claw. Further, the guide means is not limited to the two pairs of stoppers 7a, 7b and 7c arranged on both sides of the continuous paper 3 in the width direction, and if the guide means is arranged on at least one side of the continuous paper 3 in the width direction. It is enough.

[0019]

As is apparent from the above detailed description, according to the present invention, it is possible to reliably suppress the occurrence of the tilted state due to the deviation of the continuous paper in the width direction during the folding operation of the continuous paper, and to divide the paper into the sorting positions. It is possible to surely identify the jam and to reduce the occurrence of jam.
