Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet bundle chuck device for holding a stacked sheet bundle between a first chuck member and a second chuck member. The present invention is suitable for a paper sheet processing apparatus such as a denomination sorter for band-sealing a predetermined number of bundles.

[0002]

2. Description of the Related Art Banknote sorters are used in financial institutions such as banks, superstores and department stores. This banknote sorting apparatus automatically sorts banknotes of a plurality of denominations mixed at random (for example, 10,000-yen bills, 5,000-yen bills, and 1,000-yen bills) into denominations via a sorting mechanism, A plurality of bill containers prepared for each denomination are stored in a stacked state. Each bill container is detachably set at a position corresponding to the distribution transport route of the distribution mechanism in the apparatus. In general, the stacked banknotes sorted into a plurality of denominations by the above-mentioned banknote sorting apparatus are accommodated in a banding portion of a denomination banding / arranging machine for banding by denomination, and banded by a predetermined number. In the vicinity of the banding portion, a chuck device for taking out the laminated banknotes after banding from the banding portion is provided.

FIG. 4 shows a conventional chuck device. The chuck device shown in the drawing is adapted to move toward or away from a band sealing portion (not shown), and slides a lower chuck claw 101 and an upper chuck claw 102 for pinching or releasing a stacked banknote M to a guide column 105. The upper chuck pawl moving arm 103 and the lower chuck pawl moving arm 104 are slidably mounted on a support 106 parallel to the guide support 105. The upper chuck pawl moving arm 103 and the lower chuck pawl moving arm 104 are respectively moved up and down along the columns 106 by the driving force of a motor (not shown). In the chuck device having such a configuration, the lower chuck claws 101 and the upper chuck claws 102
When holding the stacked banknotes M, the lower surface of the stacked banknote M is
1 and in this state, the upper chuck pawl moving arm 10
3, the stacked banknotes M are lightly held between the two chuck jaws 101 and 102, and then the upper chuck jaw moving arm 103 and the lower chuck jaw moving arm 104 are moved closer to each other to move both the chuck jaws 101 and 102. Thus, the stacked banknotes M are held at a predetermined chuck pressure.

[0004]

However, in the above-described chuck device, the upper chuck pawl moving arm 103 and the lower chuck pawl moving arm 104 are driven by different motors. It is difficult to control the current value to each motor when the stacked bills M are clamped between the two chuck claws 101 and 102 by moving the lower chuck jaw moving arm 104 and the lower chuck jaw moving arm 104 closer to each other.
It is also difficult to set the chuck pressure when sandwiching the stacked banknotes M by 01 and 102. Further, since the lower chuck claws 101 and the upper chuck claws 102 hold the stacked banknotes M by the torque of the corresponding motors, the lower chuck claws 101 and the upper chuck claws 102 separate the stacked banknotes M. When sandwiched, the torque of the motor is defeated by the reaction force of the stacked banknotes M, and the reaction force causes both or one of the chuck claws 101 and 102 to move, thereby strongly holding the stacked banknotes M. There was a problem that could not be.

Since the lower chuck pawl 101 and the upper chuck pawl 102 are connected to the lower chuck pawl moving arm 104 and the upper chuck pawl moving arm 103, respectively.
Each of the chuck jaw moving arms 103 and 104 may slightly move down due to the own weight of the corresponding chuck jaws 101 and 102, and the chuck jaws 101 and 102 enter the band sealing portion to hold the stacked banknote M. At this time, there arises a problem that the upper chuck claw 102 hits the stacked banknote M and cannot pinch the stacked banknote M. SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problem of the chuck device, and can easily perform drive control and chuck pressure setting of a holding member, that is, a chuck member that holds a sheet bundle. An object of the present invention is to provide a sheet bundle chuck device having a simple structure capable of preventing movement of a chuck member due to a reaction force of an object, that is, a sheet bundle, or movement of the chuck member due to its own weight.

[0006]

A second chuck member movably mounted on the first chuck member, and driving means for moving the second chuck member with respect to the first chuck member. Thus, the sheet bundle is held or released between the first chuck member and the second chuck member. In the chuck device according to the present invention, the second chuck member is moved with respect to the first chuck member by the driving means, so that the object to be pinched, that is, the sheet bundle, is held between the first chuck member and the second chuck member. To hold or release.
Therefore, it is possible to perform the drive control of the driving means and the setting of the chuck pressure based on the moving distance of the second chuck member with respect to the first chuck member. The chuck pressure setting can be simplified.

The second chuck member has a locked member, and the first chuck member engages with the locked member at a holding position for holding the sheet bundle with the second chuck member. A first latch mechanism for holding and fixing the second chuck member, and a second latch member engaged with the locked member at a standby position where the second chuck member is separated from the first chuck member and waits. It is preferable to have a second latch mechanism for holding and fixing the chuck member. Thus, the first latch mechanism engages with the locked member at the holding position where the sheet bundle is held between the first chuck member and the second chuck member, and holds and fixes the second chuck member. As a result, the movement of the second chuck member due to the reaction force of the sheet bundle can be suppressed. Further, the second latch mechanism is engaged with the locked member at a standby position where the second chuck member waits away from the first chuck member,
Since the second chuck member is held and fixed, the movement of the second chuck member due to its own weight can be suppressed.
