BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card cleaning machine for cleaning cards such as IC cards.

[0002]

2. Description of the Related Art In recent years, many IC cards have come into circulation. Although IC cards are superior to conventional magnetic cards in terms of security and the like, since they are expensive, cards that are no longer used are collected and reused. When reusing, it is necessary to remove dirt adhering to the card, but card cleaning machines that automatically clean the card without manual labor have been conventionally known.

As an example of a conventional card cleaning machine, Japanese Unexamined Patent Publication No. Hei 9 (1998)
What is described in Japanese Patent Laid-Open No. 136068 and Japanese Patent Laid-Open No. 10-85685 will be briefly described. A conventional card washing machine is provided with a hopper for storing cards to be washed above a container, and a plurality of transportation rollers and a plurality of washing rollers are provided from the hopper to the card outlet. The cleaning roller is porous, and the cleaning liquid is transmitted from the cleaning container in which the cleaning liquid is stored to the cleaning roller via the plurality of rollers. The card that has passed through the cleaning roller is cleaned with a cleaning liquid.

Further, the conventional card cleaning machine is provided with a drying heat roller for drying the card passing through the cleaning roller. A halogen lamp serving as a heat source is provided in the heat roller. The card that has passed through the heat roller is dried and stored in the card receiving portion.

On the other hand, in order to solve the above-mentioned drawbacks of the conventional card washing machine, the inventor of the present invention carries a card from the lower side to the upper side by nipping it with a roller and conveys the card while nipping the card with a washing roller. I thought about a washing machine. This card cleaning machine stores a hopper for storing cards before cleaning, a feeding roller for feeding cards one by one from the hopper to a cleaning roller, a scraping device for scraping off the cleaning liquid adhering to the cleaned card, and a cleaning liquid. And a feeding roller for feeding the card scraped off to a stacker for storing the card.

This card cleaning machine is provided with a scraping means which is a rubber plate-like member, and scrapes off the cleaning liquid or the like adhering to the cleaned card, so that it is not dried through the heat rollers. Reliable removal of water. Also, the device can be simplified and downsized,
It also contributes to the cost reduction of the entire device.

[0007]

However, especially when a cleaning liquid containing a large amount of a surfactant is used in order to enhance the cleaning power, the diffusibility of the cleaning liquid is increased, and the card can be dried sufficiently by only scraping means. There was a problem that could not be done.

Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to reliably dry a card even when a cleaning liquid having a high surfactant content is used. To provide a card washer.

[0009]

The present invention has the following constitution in order to achieve the above object. That is, according to the card cleaning machine of the present invention, a hopper capable of storing a plurality of cards to be cleaned, and a stacker capable of storing a plurality of cards after cleaning, the hopper being downward and the stacker being upward. A card cleaning machine in which the cards are conveyed from below to above, and at least one card is arranged on each side of the conveyed card, and each card is rotated in contact with both sides of the card. Insert the card in the hopper to the position where the roller and the cleaning roller are installed.
A feeding means for feeding one by one, a cleaning liquid ejecting means for ejecting a cleaning liquid toward the cleaning roller and / or a card located near the cleaning roller, and a cleaning liquid adhering to the card passing through the cleaning roller, etc. At least one scraping means for scraping off and a card that has passed through the scraping means are placed on both sides of the card so as to sandwich the card from both sides, and the cleaning liquid that is elastically deformed and comes into contact with the card surface and adheres to the card surface It is characterized in that it is provided with an elastic roller that spreads the elastic members and the like, and a sending-out means that sends out a card that has passed through the elastic roller so as to be stored in the stacker. By adopting this configuration, the rollers made of elastic material elastically deform and rotate while contacting both sides of the card, so that the cleaning liquid etc. adhering to the card surface is spread out thinly and the drying is promoted. it can.

Further, by providing a blower for blowing air toward the card sandwiched by the elastic roller and / or the card passing through the elastic roller, the elastic roller pushes thinly. It is possible to more reliably dry the spread cleaning solution and the like.

Furthermore, a heater for heating the air blown from the blower may be provided. according to this,
When the humidity is high, you can raise the temperature of the wind applied to the card to make it easier to dry.

Further, since the first water absorbing body is provided in contact with the elastic roller in order to wipe off the water adhering to the elastic roller, it contacts the next card before the elastic roller dries. Then, it is possible to prevent the next card from getting wet.

The present invention is characterized in that a second water absorbing body is provided in order to wipe off moisture adhering to the card that has passed through the elastic roller. The operation of this structure will be described below. Especially, when a detergent containing a large amount of surfactant is used, if a little water remains, the remaining water becomes spherical, and in this state, it does not easily dry. Even if the spherical water droplet is spread by the elastic roller, the water droplet only moves to the end portion of the card, and it is difficult to dry. Therefore, the second water absorbing body is provided, and the first water absorbing body is configured to wipe off the water droplets pushed out to the end of the card by the elastic roller, whereby the card can be completely dried.

The same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted. Heaters 73 and 74 are provided in front of the blowers 60 and 62 (directions in which the wind is directed). The air output from the blowers 60 and 62 passes through the heaters 73 and 74 to be heated and then becomes warm air to hit the card 28, so that the card 18 is surely dried even when the humidity is high or the temperature is low. Can be

Further, temperature sensors 75 and 76 for measuring the temperature of warm air are provided in front of the heaters 73 and 74, respectively. By providing the temperature sensors 75 and 76, if the temperature sensors 75 and 76 detect that the temperature can be sufficiently dried without hot air, the heaters 73 and 74 are not operated. It is preferable that the operation is performed by sending a mere wind instead of the warm air, because the electricity bill and the like during the operation of the heater can be reduced. In addition,
Each of the temperature sensors 75 and 76 is connected to a CPU (not shown), and when the temperature sensors 75 and 76 detect that the temperature is below a predetermined temperature, the CPU automatically operates the heaters 73 and 74. If the temperature sensors 75 and 76 detect that the temperature is higher than a predetermined temperature, C
In order for PU to automatically stop each heater 73,74,
The heater may be automatically turned on and off.
By doing so, it is possible to save the trouble of turning the heater on and off and reduce the electricity bill while the heater is operating.

On each outer side of the pair of elastic body rollers 58 (the side facing the side where the elastic body roller 58 comes into contact with the card, not the side where the elastic body roller 58 comes into contact with the card), there is a mall shape as an example of the first water absorbing body. Absorption brush 70 composed of fibers
Are arranged in contact with each other. Since the water absorbing brush 70 is provided in contact with the elastic roller 58 as described above, the water absorbing brush 70 wipes off the moisture adhering to the elastic roller 58. Therefore, the elastic roller 58 can be kept in a dry state at all times, and even if moisture adheres to the elastic roller 58, the moisture is not returned to the card to accelerate the drying of the card. The water absorbing brush 70 of the present embodiment absorbs water by the capillary action sucking water by the capillary phenomenon.

A second water absorbing body 72 is provided above the elastic body roller 58 at a position where both sides of the card passing through the elastic body roller 58 are sandwiched. As an example of the second water absorbing body, it is possible to employ a water absorbing brush using the same molding fiber as that provided in contact with the elastic roller 58. By arranging the water absorbing brush 72 above the elastic roller 58, the following effects are obtained. That is, the elastic roller 58 is made of soft rubber and rotates while contacting the surface of the card 18 by elastically deforming the surface of the card 18, so that even a small amount of water that cannot be scraped off even by the plate-shaped body 56 is thinly spread out. However, if the water content is spherical due to the use of a cleaning liquid containing a large amount of surfactant, the elastic roller 58 cannot spread the water droplets thinly, and simply spread it on the edge of the card. It just pushes out water droplets. Therefore, the water absorbing brush 72 wipes off the water droplets that are not dried by being pushed by the elastic roller 58 and not dried, so that the card 18 can be completely dried. The water absorbing brush 72 is preferably arranged so as to come into contact with the end of the card 18 so that water droplets accumulated on the end of the card 18 can be wiped off.

The direction of the warm air coming out from the blowers 60, 62 is the position where the elastic roller 58 and the water absorbing brush 70 are provided, and the water absorbing brush 72 provided above the elastic roller 58. It is designed to face the designated position. Therefore, the card 18 is surely dried, and the water absorbing brushes 70, 72 themselves are also dried, so that the moisture adhering to the water absorbing brushes 70, 72 does not adhere to the card 18 sent next. To be dried.

The first water absorbent body and the second water absorbent body are not limited to the water absorbent brushes composed of the above-mentioned molding fibers, but may be those capable of absorbing water droplets. For example, various materials such as sponge and simple cloth can be adopted.

Although the present invention has been variously described with reference to the preferred embodiments, the present invention is not limited to these embodiments, and many modifications can be made without departing from the spirit of the invention. Of course.
