Description

[Detailed description of the invention] "Field of industrial application" This invention relates to a paper sheet counting machine that distinguishes different types of tickets.

"Prior Art and Problems" In general, a paper sheet counting machine for discriminating different types of paper sheets counts paper sheets such as banknotes, and also detects different types of paper sheets mixed in the paper sheets being counted. This is how it is done.

By the way, the conventional paper sheet counting machine that distinguishes between different types of tickets is
As shown in Figure 1, paper sheets (hereinafter referred to as banknotes)
When a banknote A is placed on the holder 1 in a horizontal position, the holder 1 rotates toward the rotary cylinder 2 disposed nearby, and the banknote A is moved between the holder 1 and the paper presser bar 3. The rotary cylinder 2 is sandwiched between the rotary cylinder 2 and the suction head 4 disposed annularly on the rotary cylinder 2. After that, a vacuum pump (not shown) operates to perform a suction action, and a drive device (not shown) moves the rotary cylinder 2 is rotated, the suction head 4... revolves around its axis, suctions and separates the banknotes A one by one and counts them, and when the banknotes A are suctioned and separated by the suction head 4, , the height of the top tip of the banknote A is detected by a different type of note discriminating device comprising a light emitter 5 and a light receptor 6 to discriminate between different types of notes (different denominations).

However, in this type of paper sheet counting machine for discriminating different types of bills, when the bill A is attracted and separated by the suction head 4... When the portion shown by ( ) bends toward the uncounted banknote A side, the different type of banknote discriminating device detects the height of the banknote A at which the banknote A curves in a folded manner. Therefore, the denomination of the banknote A can be accurately determined. The problem was that I couldn't do it.

This idea was made in view of the above circumstances,
The purpose of this is to prevent the upper tip of the banknote from bending when the banknote is attracted and separated by the suction head, and to accurately distinguish different types of banknotes (denominations). An object of the present invention is to provide a ticket discrimination paper sheet counting machine.

``Means for Solving the Problems'' In order to achieve the above object, the present invention provides a cylindrical suction system mounted at a position radially away from the rotation center of the rotating cylinder and spaced apart from each other in the circumferential direction. Rotate the head around an axis parallel to the rotation center, and from a plane formed by cutting out a part of the side surface of the suction head approximately in the vertical center of the paper sheet in a horizontal position, While vacuum pressure is applied before and after the area where the flat surface directly faces the surface of the paper sheet, each sheet is suction-separated and counted one by one, and when the sheet is suction-separated by the suction head, the paper sheet is In a paper sheet counting machine for discriminating different types of bills, which irradiates light onto leaves and distinguishes between different types of bills based on the transmitted light and reflected light, when the paper sheets are separated by suction by the suction head, the The suction head is provided with a holder for holding the upper end of the paper sheet in an upright state, and the holder is located at the upper part of the suction head and in contact with the cutout plane on the outer periphery of the suction head. The suction head is configured to protrude radially outward from the rotation range of the suction head at different positions.

"Operation" The suction head rotates while applying vacuum pressure to the surface of the paper sheets, attracting them one by one and peeling them off. During this peeling, there is a holder that protrudes from a part other than the paper sheet suction part of the suction head that is about to adsorb the bill, and a holder that has already turned up the paper sheet adjacent to the holder. The paper sheet is held between the suction head and the holder immediately after it is turned over.

"Example" An example of this invention will be described below in Figures 2 and 3.
This will be explained based on the diagram. Note that the same reference numerals in the figure as in FIG. 1 indicate the same constituent elements, so the explanation thereof will be omitted.

A mounting plate 10 is mounted above the suction head 4 on the rotary tube 2 disposed near the holder 1.
They are respectively attached so as to protrude slightly to the right with respect to the suction surface 4'. A holder 11 with which banknotes A are held in contact with is erected on the upper surface of the protruding end portion of the mounting plate 10 (a portion eccentric from the central axis of the suction head 4). That is, as shown in FIG. 3, this holder 11 is installed on the suction head 4b which, when the banknote A is attracted by the suction head 4a and separated after being turned over, uses its elasticity to suck the banknote A next. The suction head 4 is held in an upright state by contacting the holder 11, which is attached to the holder 11, and performs adsorption and separation.
than the outer circumferential surface of the suction head 4 so that the holder 11 on the top a contacts the banknote A and the banknote A is held between the holders 11, 11 on the suction heads 4a, 4b. Installed in a protruding position.

Next, the operation of the paper sheet counting machine for discriminating different types of bills configured as described above will be explained.

First, as in the conventional case, when banknotes A to be counted are placed on the holder 1, the banknotes A are rotated toward the rotary cylinder 2, and the banknotes A are sequentially collected one by one by the suction head 4. It is adsorbed and separated and counted. In this way, when the banknote A is suction-separated by the suction head 4a, the elasticity (returning force) of the banknote A causes the banknote A to move to the holder 11 on the suction head 4b which will perform the suction-separation next. It is held in an upright state so that its upper tip (denomination discrimination part) does not bend due to contact, and the holder 11 on the suction head 4a comes into contact with the banknote A, so that each suction head 4
The banknote A is held between the holders 11 and 11 on a and 4b. When the bill A is held in this way, the bill A is prevented from shaking due to air resistance or vibration of the machine during counting, and in this state, a A bill discriminating device measures the top tip of the bill A. As a result, even if there is a wide banknote, such as a 10,000 yen note, the upper end of the banknote is prevented from bending, and the different denominations can be discriminated by the different banknote discriminating device. In addition, according to the above embodiment, banknote A
If only the number of banknotes A is to be counted, the counting can be performed without any problem even if the banknote A is bent in a bent manner, as in the conventional case.

Next, other embodiments will be described. In the above embodiment, the mounting plate 10 is provided on the suction head 4, and the round bar-shaped holder 11 is provided on the mounting plate 10, but the structure is not limited to this, and for example, as shown in FIG. A support pin 12 may be erected on the suction head 4, and a disk 13 having a diameter larger than that of the holder 11 may be attached to the support pin 12. With this structure, the banknote A The outer periphery of the disc 13 on the suction head 4 that has suctioned and separated the banknote A and the outer periphery of the disc 13 on the suction head 4 that has suctioned and separated the next banknote A are attached to the holder of the above embodiment. 1
1 and 11 for a longer period of time.

"Effects of the invention" As explained in detail above, this invention provides a holder for holding the upper end of the paper sheet in an upright state when the paper sheet is adsorbed and separated by the suction head. Since the structure is installed in a position other than the suction surface of paper sheets, when peeling them off,
A holder protrudes from a part other than the paper sheet suction part of the suction head that is about to suction banknotes, and a holder of the suction head from which paper sheets have already been turned over, which is adjacent to the holder. Since the paper sheets are held in an upright position immediately after being turned over, the paper sheets to be measured by the optical sensor are in an extremely stable state, and therefore cannot be read by the optical sensor. This has the excellent effect of making it possible to accurately distinguish between different types of fruit and paper leaves as the data obtained is extremely stable.
