JPH05262443A - Duplicate feed detector for card and the like - Google Patents

Abstract

PURPOSE:To provide a duplicate feed detector for cards and the like by which duplicate feed can be detected reliably without damaging the cards and the like to be conveyed. CONSTITUTION:An insertion sensor 3, pull-in rollers 4, a standard unit 5 having a length sensor 8, duplicate feed preventive rollers 10, a passing sensor 6 and conveying rollers 7 are arranged in order in a conveying passage for cards and so on. Detecting signals of the length sensor 8 arranged upstream of the duplicate feed preventive rollers 10 and passing sensors 7a and 7b arranged downstream of them are inputted to a control means 11. The control means 11 detects that duplicated feed is caused when the passing sensors 7a and 7b do not detect the passing of the cards and so on even if a prescribed time is passed after the length sensor 8 detects the passing of the cards and the like.

招来し、利用効率を低下させる。In the conventional card type conveying apparatus as described above, a plurality of cards are inserted from the insertion opening due to error or mischief.
When the cards are overlapped and inserted into the device, the overlapped cards cause a jam inside the device and the operation of the device must be stopped. This leads to a situation that cannot be obtained and reduces utilization efficiency.

る虞れも高くなっている。In particular, in recent years, an automatic vending machine which can use both cards and bills and which can insert cards and bills from a single insertion port has been developed. In this case, it is necessary to secure a relatively large vertical dimension (thickness direction dimension) of the insertion slot in order to facilitate acceptance of weak banknotes, and as a result, a plurality of cards may be erroneously inserted. This is also high.

るフォトインタラプタ等のセンサ１０９とを備える。By the way, as an apparatus for detecting double feeding of banknotes, for example, ones shown in FIGS. 2 (a) and 2 (b) are known. This paper money double feed detection device is a pair of pulleys 101 arranged coaxially at a predetermined interval, and a base spool located coaxially between both pulleys 101 and having a diameter slightly larger than the pulley 101.
A base 102, a carrier 102, an inner carrier belt 103 and an outer carrier belt 105, which are wound around the outer peripheral surface of the pulley 101 to form a banknote transport path in their contact areas.
When two or more banknotes are about to pass by causing the circular arc-shaped banknote contact edge 107a to closely face the outer peripheral surface of the second banknote, the banknote M is sandwiched between it and the base pulley 102, and the direction of the arrow is indicated. Double feed detection plate 107 and double feed detection plate
The sensor 107 includes a sensor such as a photo interrupter that detects the rotation of the switch 107 in the direction indicated by the arrow.

Is urged in the direction opposite to the rotation direction indicated by the arrow, and the limit of the rotation range in the opposite direction is set by the stopper 115.

When fed into the gap between the double feed bill and the bill, the double feed bill cannot pass through the gap smoothly and hits the bill contact edge 107a of the double feed detection plate 107 at the leading end thereof, and the bill is fed in the direction of the arrow. Then, the sensor 109 is turned on to detect double feeding.

Cannot be formed in a curved shape like a bill conveyance path, and it may be necessary to form a conveyance path composed of belts 103 and 105 in a linear shape as shown in FIG.

The work required skill to determine the detection accuracy. In addition, when the bill double feed detection device is also used for double feed detection of cards, there is no choice but to make the transport path linear as shown in FIG. This causes problems such as a reduction in the degree of freedom in the installation location of the double feed detection device. Also, double-fed cards are
1 and the multi-feed detection plate 107, the upper corners of the upper cards and the like contact the bill contact portion 107.
Since it is easy to lock the double feed detection plate 107 by hitting a, the plate 107 cannot rotate in the direction of the sensor 109 and stable double feed detection becomes difficult.
There was a problem that the tips of the cards were damaged by the friction with the plate 107.

類と紙幣とを判別すること従来と同様である。In this embodiment, between the length sensor 8 for detecting the passage of the cards and the passage sensor 6, only one card discharged from the standard unit 5 is allowed to be conveyed. To prevent this, the double feed prevention roller 10 is sandwiched across the transportation paths for the cards.
Opposite. In this case, the transport roller 9 of the standard unit 5
And the distance between the double feed prevention roller 10 and the double feed prevention roller 1
It goes without saying that the distance between 0 and the transport roller 7 is set smaller than the length dimension of one card. In addition, the distance between the upper and lower double feed prevention rollers 10 is one sheet.
Slightly thicker than the thickness of the cards and thinner than the thickness of the two cards, for example 0.3 as in a commercially available prepaid card.
In a vending machine handling thin cards of about mm, it is preferable to set it to about 0.4 mm. The car
In a vending machine that accepts bills as well as bills,
The standard unit 5 is provided with a width sensor to discriminate between cards and bills as in the conventional case.

When the insertion sensor 3 detects the insertion of cards, the motor 4
A, 10A and 7A are driven to rotate the pull-in roller 4, the double feed blocking roller 10 and the transport roller 7 to transport the cards into the apparatus. Alternatively, when it is determined that the cards have a prescribed length based on the detection signal from the length sensor 8, the motor 9A is driven and the transport roller 9 is rotated in the normal direction. Discharge to the downstream side. On the contrary, when it does not have the specified length, it is reversed and returned to the insertion opening 1.

When a card or the like is inserted, the insertion sensor 3 detects the insertion of the card or the like, and the control means 11 actuates the moder 4A based on the insertion detection signal to cause the retractable roller pair 4 to operate the card or the like. Nip the tip of and feed it into the standard unit 5. In the standard unit 5, the length sensor 8 detects the length of the insertion cards, and if the cards match the reference length, the transport roller 9 is rotated in the forward direction to rotate the cards. Is discharged from the standard unit 5, and if it does not match, the transport roller 9 is reversed and returned to the customer. When the number of cards discharged from the standard unit 5 is one, the card can pass through the gap between the double feed blocking roller pair 10 and one card that has passed through the passage sensor 6.
The sheets are nipped by the transport rollers 7a and 7b and further transported into the apparatus. The control means 11 monitors the time from when the cards pass the length sensor 8 to when the card passes the passage sensor 6. However, since double feeding does not occur, a warning means or a stopping means is provided. It does not work.

When the cards are discharged, the double feed cards cannot pass through the gap between the double feed blocking roller pair 10, so that the passage sensor 6 is closed.
It does not detect the passage of birds. In this case, the control means 11 determines that the double feeding has occurred when the passage sensor 6 does not detect the passage even if a predetermined time has elapsed after the cards passed the length sensor 8, and the warning means or Activate the stopping means.
