Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a conveyor belt unit opening / closing device in a banknote processing machine in which an upper conveyor belt unit, which is vertically positioned and communicated with each other so that a banknote can be conveyed, can be opened and rotated so that maintenance and the like can be performed.

[Prior art]

Conventionally, a banknote transport unit equipped with a pulley and a transport belt located above the tension roller is located above the banknote transport unit equipped with a transport belt for transporting banknotes and a tension roller. In the banknote handling machine configured to be rotated so as to be opened so as to be openable, the tension roller has a mounting structure in which the tension roller is simply elastically pressed.

[Problems to be solved by the device]

Therefore, when rotating and opening the upper unit about the axis during maintenance, the front part of the unit in the direction of rotation will come into contact with the tension roller, and the unit can only be rotated just before that. It is not possible to do so, the opening angle is limited, and the front part of the unit approaches as the tension roller is still in contact with the conveyor belt, so if the part gets jammed with bills, collection will be troublesome. Or, there was a problem that the bills would be damaged. The present invention has been made in view of the above circumstances, and makes it possible to open the upper conveyor belt unit, which is vertically positioned and communicated so that banknotes can be conveyed, as much as possible.
It is an object of the present invention to provide a conveyor belt unit opening / closing device for a banknote handling machine that facilitates maintenance and the like.

[Means for Solving the Problems]

In order to achieve the above object, the present invention provides a conveyor belt 55 wound around a pulley 54 fixed to a shaft 52, and a conveyor belt 55 paired with the conveyor belt 55 and wound around a pulley 57 supported on a shaft 56. Conveyor belt unit with rotated conveyor belt 58
A transport belt unit 65 having a transport belt unit 23 and a transport belt 69 that is swingably supported about a shaft 52 of the transport belt unit 23 and is wound around a pulley 68 supported by a shaft 57.
And a tension roller 48 provided in a transfer section between the conveyor belts 55 and 58 of the conveyor belt unit 23 and the conveyor belt 69 of the conveyor belt unit 65 and provided so as to be able to come into contact with and separate from the conveyor belt 55, In the banknote handling machine including 49, the tension rollers 48 and 49 are swingably supported by a shaft 56 of the conveyor belt unit 23, and are rotated by torque springs 61 and 62 toward the conveyor belt 55. The roller arms 59, 60 are rotatably supported by the swinging tips of the roller arms 59, 60, and the roller arms 59, 60 are further swingable by the shaft 67 of the conveyor belt unit 65 at the swinging tips. The pin 91, 92 engaged with the engaging groove 89, 90 formed at the swinging tip of the roller arm rotating piece 88 supported by the is fixed.

[Action]

Therefore, when the conveyor belt unit 65 is rotated about the shaft 52 in the opening direction, the distance between the shaft 56 of the conveyor belt unit and the shaft 67 of the conveyor belt unit 65 approaches the shaft 67 side so that the distance between the shaft 56 and the shaft 67 of the conveyor belt unit 65 becomes shorter. To do. As a result of this approach, the pins 91 and 92 connecting the roller arm rotating piece 88 and the roller arms 59 and 60 are moved to the roller arm rotating piece 88.
By shortening the line that connects the shaft 67 that supports the roller arm 59 and the shaft 56 that supports the roller arms 59 and 60,
Pin 91, 92 for connecting the roller arm 59, 60 with the engaging groove 8
The 9,90 part rotates backward. With this rotation, the pulley 57 of the shaft 56 and the pulley of the shaft 67
The tension rollers 48, 49 located in the transport path between the transport belt unit 68 and 68 are retracted from the transport path, and the transport belt unit 65 can be largely opened to the transport belt unit 23.

When you operate to grasp 29 together, lock release lever 12
The lower end of 8 is locked by connecting pins 205 and 206 to lock cams 126 and 127.
Since the lock release lever 128 is connected to the shaft 124b,
In the form of being guided by 125b, it moves downward while rotating slightly counterclockwise in FIG. 2, while the lock cam 126,
127 rotates clockwise in FIG. By the rotation of the lock cams 126, 127, the engagement state between the lock cams 126, 127 and the lock pins 120, 121 is released, while the link 139 connected by the lock cam 127 and the connection pin 209 moves to the right in FIG. . By the movement of the link 139 to the right, the release pin on the link 139 that was at a position separated from the lock arm 133
141 moves to a position almost in contact with the lock arm 133. In this state, the third conveyor belt unit 1 is attached to the shaft 3
When it is rotated upwards about, the lock pin 135
It pivots upward and moves in the long hole 133b of the lock arm 133. When the third conveyor belt unit 1 is swung so that the lock pin 135 moves to the upper limit position of the long hole 133b of the lock arm 133, the lock arm 133 causes the torque spring 1 to move.
Since it is urged to rotate counterclockwise in FIG. 2 by 37, the lock arm 133 tries to rotate counterclockwise in FIG. However, since the release pin 141 of the link 139 has already moved to a position where it is almost in contact with the lock arm 133, the lock arm 133 cannot rotate. In this state, the lock release lever 12
When 8 is operated to be separated from the lever 129, the lock releasing lever 128 moves slightly upward while rotating clockwise in FIG.
126 and 127 rotate counterclockwise. When the lock cams 126 and 127 rotate counterclockwise, the link 139 further moves to the left in FIG. 2, and is rotated by the release pin 141 while being biased in the same direction by the torque spring 137. For the first time, the lock arm 133, which has been restricted, rotates counterclockwise in FIG. 2, and the lock pin 135 of the third conveyor belt unit 1 becomes
Entering into the hook-shaped long hole 133b of the lock arm 133, so that the third conveyor belt unit 1 is locked to the open position with respect to the second conveyor belt unit 10 as shown in FIG. become. At this time, the third conveyor belt unit 1 is swung upward to separate from the second conveyor belt unit 10,
The stopper cam 110 formed at the end of the third conveyor belt unit 1 on the swinging end side is provided with a stopper cam 110.
The engagement state with a part of the stopper 106 provided at 0 is released, and this stopper 106 is used for the second conveyor belt unit 1.
It swings in the direction closer to the lock levers 102, 103 provided on 0. Therefore, the conveyor belt 17 of the second conveyor belt unit 10
When the space between the second conveyor belt unit 1 and the conveyor belt 6 of the third conveyor belt unit 1 is opened, the lock levers 102, 103 provided on the second conveyor belt unit 10 and the first conveyor belt unit 23 are provided. It becomes impossible to release the locked state with the lock pins 100 and 101. On the other hand, in order to release the state in which the third conveyor belt unit 1 is locked in the open position with respect to the second conveyor belt unit 10, the above operation is reversed to
First, the lock pin 135 and the hook-shaped long hole 133b of the lock arm 133.
It suffices to release the locks for and to swing the third conveyor belt unit 1 downward. Next, a mechanism related to the fourth conveyor belt unit 65 will be described.

When the shaft 67 of the conveyor belt unit 65 moves downward about the shaft 52, the roller arm rotating piece 88 and the roller arms 59, 60 are moved.
Since the pins 91 and 92 for connecting the roller arm are located rearward of the line connecting the shaft 67 supporting the roller arm rotating piece 88 and the shaft 56 supporting the roller arms 59 and 60,
88 and roller arms 59 and 60 also rotate rearward. With this rotation, the pulley 57 of the shaft 56 and the pulley of the shaft 67
The tension rollers 48, 49 located in the transport path between the transport belt unit 68 and 68 are retracted from the transport path, and the transport belt unit 65 can be largely opened to the transport belt unit 23.
