A stapler sorter for stapling, which relates to a jogger device of a stapler sorter for aligning sheets stored in the bin tray within a predetermined range for stapling.

Referring to the accompanying drawings, a conventional jogger device proposed in US Patent No. 4,928,941 is briefly described as follows.

1 is a plan view of a conventional jogger, and FIG. 2 is a side view of a conventional jogger.

In the drawings, 40 is a tray support, 50 is a tray, 50a is an incision, 60 is a guide groove, 70 is a rotating shaft, 80 is a half-gear gear, 100 is a motor, 110 is a jogger arm, and 120 is a jogger bar.

Referring to the operation of the general stapler sorter briefly, after storing the discharged paper in each tray 50 inclined to a predetermined inclination, the stapler is placed to operate the jogger device to position the paper on the tray 50. The paper is aligned so that the edge is out of alignment with the cutout 50a formed to staple to the side, and when the jogger is completed, a stapler (not shown) is operated to staple the paper on the tray 50. do.

Looking at the conventional jogger device operated as described above in detail as follows.

Guide grooves 60 formed on the respective trays 50 which constitute the rotary shaft 70 at the position corresponding to the stapler, and inclined the jogger bar 120 connected to the rotary shaft 70 and the jogger arm 110. ) And the vandal gear 80 at the lower end of the rotating shaft 70 to engage with the motor 100 provided in the tray support 40 located at the lower end of the tray 50. In this configuration, the jogger bar 120 is rotated by the forward and reverse rotation of the motor 100 to align the sheets stored in the tray 50.

Since the paper is gradually moved to the upper side according to the gradual upward movement often occurs when the paper is not aligned, since the jogger bar 120 is arcing around the rotation axis 70 of the jogger bar 120 When the jogger arm 110 is long because the rotation range is limited, the jogger bar 120 comes into contact with the rear end of the paper having a small length in the longitudinal direction. Jogger bar 120 prevents short because there is a problem in the alignment of the paper is not possible.

In addition, since the driving force of the motor 100 is directly transmitted to the jogger bar 120, even after the paper loaded on the tray 50 is pushed out, the jogger bar may have an error in the paper size or a driving error of the motor 100. When 120 continues to rotate, the paper impedes the rotation of the jogger bar 120 and thus loads the motor 100, and the jogger bar when the paper is bent by the rotation of the jogger bar 120. The paper unfolding force is applied at the moment when the 120 returns to the initial position, and the paper is disturbed.

As a result, the jogger bar 5 stops.

Accordingly, the present invention prevents the pressure spring 19 from directly transmitting the load to the motor 11 that prevents the movement of the jogger bar 5 generated when the paper is aligned, thereby operating the motor 11. This prevents malfunction due to the load at the time, improves operational reliability, extends the life of the motor 11, and prevents the paper from being disturbed at the moment when the jogger bar 5 returns to the initial position.

As described above, in the present invention, since the jogger bar moves in a straight direction, even a small size of paper can be aligned, and since the jogger bar moves at an inclination such as a tray, only a minimum size and space are required. Since the contact point of the jogger bar is not displaced, it is possible to realize reliable paper alignment operation, and to use the small size of the jogger arm, and also the position of the tray is not limited by the position of the tray even when positioning the rotation axis which is the rotation point of the jogger arm. It can be set freely, and as a result, it is possible to implement a reliable jogger operation and to miniaturize the product.

In addition, the present invention has the effect of preventing the stopping force of the paper alignment is completed is not directly transmitted to the motor, and stops the movement of the jogger bar, so that the paper is not disturbed when restored to the initial position.
