Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a system for automatically correcting the position between constituent elements.
In particular, the present invention relates to a paper sheet handling device suitable for reducing delivery errors and improving reliability when paper sheets are delivered between each component by a transport mechanism.

[Conventional technology]

Conventionally, as this type of device, there is one shown in Japanese Patent Laid-Open No. 59-33590. In this example, banknotes 10 in the storage section 4
is grabbed all at once by the arm section and delivered to the conveyance section 6.

[Problem that the invention seeks to solve]

The above conventional technology does not take into consideration the adjustment of the paper delivery position and the movement control amount of the arm is a fixed value, so when assembling the device, each component must be adjusted within predetermined standard dimensions. There was a problem that it had to be done.

An object of the present invention is to automatically control and correct the delivery position so as to reduce the effects of variations in component dimensions during manufacture of these components, assembly errors between each component, and long-term accuracy changes in the transport mechanism. It provides a way to control the

[Means for solving problems]

The above purpose is to provide a position detection means on the movable part of the transport mechanism,
Furthermore, each component is provided with one or more position detection means or auxiliary means for position detection, and when the position needs to be adjusted or corrected, the control unit moves the movable part and uses a physical quantity to recognize the position. , for example, motor ON time, rotation amount,
Number of driving pulses.

Furthermore, this is achieved by detecting the absolute spatial positions between the constituent elements.

[Effect]

The position sensing means can measure dimensions between the components. As a result, the control unit can store the position data, so after the position detection work is completed, hand delivery control can be realized based on the position control information that is optimal for handing over. Thereby, assembly variations between each component and long-term accuracy changes can be reduced.

〔Example〕 An embodiment of the present invention will be described below.

First, the banknote handling device and its operation will be briefly explained. Figure 1 shows the external appearance. The conveyance mechanism section 5 that transfers banknotes is equipped with a hand 4, and deposit/withdrawal ports 1.
Cassette 3 (paper sheet storage section) counting section 2. Furthermore, the banknote handling device is comprised of a block separation mechanism 10 that separates a suitable number of banknotes into blocks from the banknotes in the cassette, and a control unit 12 that controls the operations of the above-mentioned parts.

゛ Next, as an example of operation, the operation of paying bills is shown in Figures 3 to 6.
This will be explained with a diagram.

As shown in FIG. 3, the banknotes are separated into appropriate numbers by a block separating mechanism 10.

Next, the hand 4 enters the cassette 3 and clamps one banknote in order to remove the banknote from the cassette 3 (FIG. 4).

Next, in order to transfer the bill to the separation section 21 of the counting section 2, the hand 4 enters the section and sets one bill (FIG. 5).

Thereafter, in the counting machine 2, the bills are separated and counted one by one from the separating section 21, and transported to the stacker 22 where they are temporarily stacked (FIG. 5).

Finally, as shown in FIG. 5, the hand 4 enters the stacker 22, holds and extracts the banknotes, moves to the deposit/withdrawal port 1, enters the stacker 22, receives the banknotes, and withdraws the money.

All of the above operations are controlled by the control section 12. The above operation ends the payment operation, and an important position control is control of the entry position of the hand 4. In the embodiment, an automatic correction method for this position is adopted. An example of this will be explained below with reference to FIG. It is assumed that this automatic position correction is performed by the control unit 12 before a transaction is started, for example, immediately after the power is turned on in the morning.

Structurally, the hand 4 includes an optical sensor 8a as a detection mechanism,
8b is installed, and the other deposit/withdrawal port 1, cassette 3
, detection pieces 9c and 9 are placed at the hand entry position of the counter 2, respectively.
d is attached, and the optical sensor has a structure that detects the detection piece at the entry position.

In the automatic correction operation, the hand 4 first descends, detects the lower limit reference position with the lower limit detection switch 7, and stops.

Use this as the reference position and ascend from here. Next hand 4
In this device, a stepping motor 11 is used as a driving force to raise the temperature.

Next, the control unit 12 drives the stepping motor 11 by one pulse in the hand upward direction, and stores the number of drive pulses from the reference position (initially O). After moving the position by one pulse, the inputs of the optical sensors 8a and 8b are checked to see if the detection piece at the hand 4 entry position has been detected.

If it is not detected, try stepping motor 11 again.
Drive the hand in the upward direction by one pulse.

Check the detection piece while memorizing the number of pulses in the control unit.

By repeating this procedure, the hand approach position A, B, C, D of each component is raised from the reference position.
Measure the dimensions of. (Dimensions can be converted by the number of pulses from the reference position.) By performing the above operation at initialization as described above, the hand entry position can be determined extremely accurately, and when trading, move at high speed based on this value. It can be performed.

According to this method, the hand entry position can be confirmed every day at the opening of the station, and by correcting long-term changes in accuracy, it is possible to always operate at the correct position.

〔Effect of the invention〕

According to the present invention, there are the following effects.

(1) Since the hand can measure and correct the entry position by itself, no adjustment is required when assembling the device.

(2) It is possible to eliminate the need to make adjustments when replacing units such as deposit/withdrawal slots and cassette counters due to breakdowns or other maintenance activities.

(3) By measuring the position of each unit during initialization every morning when the device is started up, the operational accuracy of the transport mechanism can be checked.
