Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is directed to sending out card-like items such as prepaid cards one by one from a card hopper to a conveyance path, and punching holes in the cards during the conveyance path. The present invention relates to a card punching inspection device that detects whether the punching is good or bad.

<Prior Art> In recent years, some prepaid cards have holes punched in order to check the reading timing of the reader and the direction of insertion into the reader.

These holes are punched after the cards are manufactured, while the cards are being transported one by one onto a transport path. A large number of cards are stored in a card hopper, and the cards are sent out one by one to a conveyance path by a card feeding mechanism having a tab etc. in order from the bottom card of this card hopper. The cards are sequentially sent out one by one to the conveyance path by a card feeding mechanism having a vacuum pad. Then, when the card is conveyed to a predetermined position below the punching portion based on the card delivery timing, punching is performed.

<Problem to be Solved by the Invention> Here, since the card is thin, it is impossible for the card feeding mechanism to reliably feed the card, and the amount of card feeding may deviate from the normal amount. If the card is not fed out normally in this way, the timing of feeding the card and the timing of punching the hole will deviate, and the hole will not be punched in the correct position. Further, if the hole making mechanism does not operate normally, problems such as not being able to make holes may occur. In the past, inspectors visually inspected punched cards to determine whether they were good or bad, but it was not possible to completely inspect all cards.

<Means for solving the problem> This invention was made to deal with the above-mentioned circumstances,
The purpose is to provide a card punching inspection device that can automatically detect whether the card punching is good or bad and can realize labor saving and rationalization of inspection.

In other words, the purpose of this is to send cards one by one from a storage means to a conveyance path in response to a predetermined timing signal, and to punch a predetermined hole at a predetermined position on the card on the conveyance path, and check whether the holes have been punched correctly. In a card hole punching inspection device that detects whether the card This is realized by a card hole punching inspection device that includes one sensor placed at one end of the card, two sensors placed at positions corresponding to the inside and outside of the card at one end of the card, and an inspection section that determines whether the hole is good or bad. be done.

<Function> According to the card hole punching inspection device according to the present invention, in the card conveyance direction immediately after punching, one optical sensor is arranged at a position corresponding to the hole position in the card conveyance direction, and an optical sensor adjacent to the sensor is arranged. Automatically determines whether the card hole punching position is good or bad according to the output signals of one sensor placed at the end of the card and two optical sensors placed at different positions in the card feeding direction. can be detected,
Labor saving and rationalization of inspection will be realized.

<Embodiment> An embodiment of the card punching position inspection device according to the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic diagram showing the configuration of the first embodiment.

A card hopper 14 storing a large number of cards 12 is arranged at one end of the conveyance path 10.

The lower part of the card hopper 14 is opened, and the card feeding mechanism 16 has a claw (not shown) under this opening, which allows cards 12 in the card hopper 14 to be transferred one by one onto the transport path. Send it out on 10.

The cards 12i immediately after being sent out onto the transport path 10 by the card feeding mechanism 16 are sent from the card hopper 14 to positions spaced apart by a predetermined interval, and each card 12 is sent out at a predetermined time interval.

The conveyance path 10 is composed of a pair of "U"-shaped conveyance guides that sandwich the card from the left and right sides, and the card is not displaced in the left-right direction, so that the hole punching position is not displaced in the left-right direction.

The card 12i in the conveyance path 10 is connected to the card feeding mechanism 16.
Each time a card is sent out, it is moved by the length of one card. Therefore, the cards 12i+ are continuously lined up in the transport path lo.

A perforation section 18 is provided at the forward end of the conveyance path 10.

The punching section 18 is interlocked with the card feeding mechanism 16, and punches a hole in a predetermined position of the card when the card is stationary within the transport path 10.

The perforated card 12ii is sandwiched between a pair of upper and lower card feed rollers 17 at the forward end of the conveyance path 10 and conveyed. This card feed roller 17 allows the card 1
2i i is transported at a slightly faster transport speed than the transport path 10. The inside of the card feed roller 17 consists of a pair of U-shaped conveyance guides that sandwich the card from left and right sides, and the card 12ii is conveyed without shifting in the left-right direction.

An optical sensor 2 is disposed in the conveyance section of the card feed roller 17 at a position corresponding to the hole position in the card conveyance direction.
1, a sensor (not shown) disposed adjacent to the sensor, and optical sensors 22 and 23 disposed at different positions in the card conveyance direction at an end along the card conveyance direction.

FIG. 2 shows an external view of the punched card.

A predetermined hole 31 is bored in the card 30 at a predetermined position. The dimensions a and b from the end of the hole 31 are determined, and if the hole 31 is not drilled at a predetermined position, the card will be defective. When the conveyance direction is the direction shown in the figure, the card is held between the U-shaped conveyance guides, so that it does not shift.

FIG. 3 shows the arrangement positional relationship of the three optical sensors 21 to 23 shown in FIG. 1. Three optical sensors 21~
Reference numeral 23 is a light emitting/receiving integrated type, and detects the presence or absence of a card based on the level of reflected light. The distance between the optical sensors 21 and 22 is less than a, and the distance between the optical sensors 21 and 23 is more than a.

The operation of this embodiment will be explained with reference to the schematic configuration diagram of FIG. 1, the timing chart diagram of FIG. 4, and the explanatory diagram of FIG. 5 showing a part of the inside of the inspection section 30 of the determination circuit.

The card 12ii punched by the punching section 18 is sandwiched between the card feed rollers 17 and conveyed.

The optical sensor 21 first reads the top of the card and then reads the hole. As shown in FIG. 4, the output signal 21s of the optical sensor 21 is 'L'° on the card, becomes '°H' at the hole, and then becomes 'L' when reading the card again.2
The signal of 1s is converted into a differential signal such as 21S' by a differentiating circuit. This differential signal 21s is used as an inspection timing signal,
The output state of the optical sensors 22 and 23 at this time is the optical sensor 22.
If the light sensor 23 is on the inside of the card and the light sensor 23 is on the outside of the card, it is determined that the product is good.

The hole part (A) shown in Figure 4 is judged to be "good", and the hole part (B)
In this case, it is judged as “defective”.In the hole (B), the sensor 21
This is an example in which the sensors 22 and 23 are both inside the card when the hole is detected, and the dimension a is larger than the specified value.

The 24s signal shown in FIG. 5 is a signal from a card presence/absence sensor (not shown), which is a sensor for prohibiting inspection between the front and rear cards. are arranged and arranged in a direction perpendicular to the

When a defect signal is output from the determination circuit, a patrol light and buzzer activation signal is output from the inspection section, and an alarm is issued to the outside. Further, a stop signal is output to the card feeding mechanism 16, and card feeding is stopped.

Note that this invention is not limited to the embodiments described above, and can be modified in various ways. For example, the configuration is not limited to the card feeding mechanism, conveyance path, etc. In the above embodiment, the conveyance path itself does not have a conveyance function, and the cards on the conveyance path are moved one card at a time by the card sending force, but the conveyance path itself may have a conveyance function. . In this case, the punching timing may be determined by determining the card position using an optical sensor or the like, and the punching mechanism may be driven.

In addition, the sensor is not an integrated light transmitting/receiving type, but a transmission type optical sensor or a sensor other than the optical sensor may be used.

<Effects of the Invention> As described above, the present invention provides a card punching inspection device that can automatically detect punching defects and realize labor saving and rationalization of inspection.
