Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention improves the efficiency of card feeding when sending card-like items such as ID cards one by one from a card hopper to a conveyance path.
The present invention relates to a card feeding inspection device that detects defects.

[Conventional technology]

In recent years, with the development of computers, ID cards have been used in various fields. This ID card has a hologram panel transferred to a predetermined position on the card surface to prevent forgery. In addition, ID so that the user's name can be written
A signature panel is also transcribed onto the surface.

These transfers are performed after the card is manufactured, while the ID cards are being transported one by one onto the transport path. A large number of ID cards are stored in a card hopper, and the ID cards are sequentially sent out one by one to a conveyance path by a card feeding mechanism having a claw or the like, starting from the lowest card in the card hopper. Then, when it is determined that the card has been conveyed to a predetermined position below the transfer unit based on the timing of card feeding,
The hologram panel and sign panel will be transferred.

[Problem that the invention seeks to solve]

Here, because the card is thin, it is impossible for the card feeding mechanism to always feed the card reliably, and the amount of card feeding may deviate from the normal amount. If the card is not sent out normally in this way, the timing of sending out the card and the timing of transfer will deviate, and the hologram panel or sign panel will not be transferred to the correct position. Conventionally, the operator visually checked whether the card feeding was good or bad. Therefore, the burden on the operator increased, and it was not possible to completely inspect all cards.

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

[Means for solving problems]

The purpose of this is to feed the cards one by one from the storage means to the conveyance path in response to a predetermined timing signal, and to transfer a predetermined transfer material to a predetermined position of the card on the conveyance path. In a card feed inspection device that detects whether the card has been fed out normally from the storage means, two pieces of paper are placed at positions corresponding to the inside of the card and the outside of the card at one end of the card in the conveying direction when the card is normally fed out from the storage means. This is realized by a card feeding inspection device that includes a sensor and an inspection section that determines whether card feeding is good or bad according to the outputs of the two sensors and timing signals.

[Effect]

According to the card feeding inspection device according to the present invention, the position of the end of the card along the feeding direction immediately after feeding is automatically determined according to the output signals of two optical sensors arranged at different positions in the feeding direction. It is possible to detect whether the feed is good or bad, which saves labor and streamlines inspection.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a card feed 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 ID cards 12 is arranged at one end of the conveyance path 10. The lower part of the card hopper 14 is opened, and a card feeding mechanism 16 is provided below this opening. The card feeding mechanism 16 has a claw (not shown), and this claw feeds the ID cards 12 of the card hopper 14 one by one to the conveyance path 10 starting from the lowest one. ID card 12 immediately after being sent out onto conveyance path 10 by card feeding mechanism 16
i is sent from the card hopper 14 to a position at a predetermined interval. Each ID card 12 is sent out at predetermined time intervals.

The conveyance path 10 consists of a pair of U-shaped conveyance guides that sandwich the card from the left and right sides, and the ID card 12 is positioned in the left-right direction. As a result, the transfer positions of the hologram panel and the sign panel will not shift in the left-right direction.

The ID card 12 in the conveyance path 10 is moved by the length of one card each time one card is sent out by the card feeding mechanism 16. Therefore, the ID cards 12 are lined up continuously in the transport path 12.

A transfer unit 18 for transferring the hologram panel and the signature panel onto the ID card 12 is provided at the forward end of the conveyance path 10 . A timing signal is supplied from a timing generator 20 to the transfer section 18 and the card feeding mechanism 16. The transfer timing of the transfer section 18 is controlled according to this timing signal, and the ID card 12 is placed in the conveyance path 10 immediately after the card feeding mechanism 16 sends out one ID card.
When the card is stationary, the hologram panel and signature panel are transferred to a predetermined position on the card surface.

Two optical sensors 22 and 24 are provided at the end of the transport path 10 on the card hopper 14 side. The optical sensors 22 and 24 are integrated light emitting/receiving types, and detect the presence or absence of an ID card based on the level of reflected light. The optical sensors 22 and 24 are provided at positions corresponding to the inner side and the outer side of the ID card 121 at the rear end of the ID card 121 immediately after being normally sent out onto the conveyance path 10 by the card feeding mechanism 16, respectively. That is, the distance between the optical sensor 22 and the card hopper 14 is less than or equal to 0, and the distance between the optical sensor 24 and the card hopper 14 is 1 or more.

The output signals of the optical sensors 22, 24 are sent to the amplifiers 26, 26, 24, respectively.
It is supplied to the inspection section 30 via 28. The timing signal supplied from the timing generator 20 to the card feeding mechanism 16 is also supplied to the inspection section 30.
identifies whether the card feeding is good or bad according to this timing signal and the output signal of the optical sensor 22.24 via the amplifier 26.28. A patrol light 32 and a buzzer 34 are connected to the inspection section 30 to notify of a feeding failure. Further, when the inspection section 30 detects a feeding failure, it supplies a stop signal to the card feeding mechanism 16 and the transfer section 18.

The operation of this embodiment will be explained. In this embodiment, the optical sensor 22 , 24 detects when the ID card 12 is successfully fed into the transport path 10 by the card feeding mechanism 16 .
As shown in Figure (a), the inside and outside of the rear end of the ID card 12i are detected. That is, at this time, the optical sensors 22 and 24 each output a detection signal and a non-detection signal. Therefore, at this time, the optical sensor 22.
The inspection unit 3 sets the combination of the 24 output signals as the reference state 2.
0, and immediately after each ID card 12 is sent out according to the timing signal supplied from the timing generator 20 to the card feeding mechanism 16, the inspection unit
By comparing the combination state of the output signals of the optical sensors 22 and 24 at 0 with this reference state, it is possible to identify whether the card feeding is good or bad.

For example, as shown in FIG. 2(b), when the card is not fed enough and the card is half fed, the optical sensors 22 and 24 output a detection signal. Further, as shown in FIG. 2(c), when the card is fed too much and the card overruns, both the optical sensors 22 and 24 output non-detection signals. When the optical sensors 22 and 24 both output non-detection signals, as shown in FIG. 2(d), the amount of card feeding is too small, or the card may not be fed at all. In the case of FIG. 2(c) and FIG. 2(d), after the timing signal is supplied to the card feeding mechanism 16 to instruct card feeding, whether a detection signal is output from the optical sensor 22, 24 or not. You can tell the difference. That is, when a card overruns as shown in FIG. 2(C), a detection signal is always output from the optical sensors 22 and 24 after the timing signal is supplied to the card feeding mechanism 16. On the other hand, if the amount of card feeding is too small as shown in FIG. 2(d), or if the card is not fed at all, the optical sensor 22.24 No detection signal is output.

When a card feeding failure is detected in this way, the inspection unit 30 activates the patrol light 32 and buzzer 34 to notify the operator of the card feeding failure, and also checks the card feeding mechanism 1.
6 and the transfer unit 18 to stop the transfer operation of the hologram panel and the sign panel to the card. As a result, an ID card whose transfer position has shifted from the normal position can be removed.

- As described above, according to this embodiment, two sensors are placed at the rear end of the card immediately after it is normally sent out from the card hopper, at positions corresponding to the inside of the card and the outside of the card. Immediately after the card is sent out, the combination of the output signals of these two sensors is compared with the reference combination when the card is sent out normally, so that it is possible to accurately detect whether the card feeding is good or bad.

Note that this invention is not limited to the two consecutive embodiments and can be modified in various ways. For example, the configurations of the card feeding mechanism, conveyance path, etc. are not limited to the above example. In the dual embodiment, the conveyance path itself did not have a conveyance function, and the cards on the conveyance path were moved by the length of one card by the card feeding force of the card feeding mechanism, but the conveyance path itself had a conveyance function. It's okay. In this case, since it is not necessary for the ID cards to be lined up continuously on the conveyance path, the optical sensor may detect the position of the front end of the card instead of the rear end of the card immediately after being sent out. In addition, the sensor may be a transmission type optical sensor rather than an integrated light emitting/receiving type, or a sensor other than the optical sensor.Furthermore, the object to be inspected for feeding defects is not limited to ID cards, but greeting cards. etc. may be used.

〔Effect of the invention〕

As explained above, according to the present invention, the position of the end of the card in the transport direction immediately after being sent out is detected using two optical sensors arranged at different positions in the transport direction, thereby automatically detecting the position of the end of the card in the transport direction. Provided is a card feeding inspection device that can detect feeding defects and realize labor saving and rationalization of inspection.
