Description

  The present invention relates to a marking device for a card that performs marking such as a print on a card surface such as a laser marker.

  Laser markers are known as card marking devices. The laser marker includes a laser unit serving as a marking head and a card transport unit that transports the card. The card transport unit includes a roller transport mechanism that includes a drive roller and a driven roller as a set, and transports the card between the drive roller and the driven roller (see Patent Document 1 below).

JP2012-11630A

  In a roller conveying mechanism in a conventional card marking device, a urethane rubber roller is generally used as a driving roller, but a plastic roller such as a polyacetal roller is used as a driven roller. In such a conventional technique, when a large amount of cards with burrs are conveyed, the driven roller is easily damaged, and if the driven roller is damaged, the scratch is compressed on the card surface, There was a problem in which the image itself was damaged or the marked drawing was disturbed.

  An object of the present invention is to deal with such a problem. That is, it is an object of the present invention to provide a card marking device capable of suppressing damage to the card and performing marking without any disturbance on the card surface.

  In order to solve such a problem, a card marking device according to the present invention has the following configuration.

  A marking head, and a card supply / conveyance section for supplying / conveying a card at a marking position by the marking head, and the card supply / conveyance section includes a roller conveyance mechanism including a driving side roller and a driven side roller. The card-side marking device is characterized in that both the driving side roller and the driven side roller are rubber rollers, and the adjacent outer peripheral surfaces are arranged with a gap smaller than the thickness of the card.

  According to the card marking device of the present invention, it is possible to suppress damage to the card and to perform marking without any disturbance on the card surface.

It is explanatory drawing which shows the whole structure of the marking device for cards (laser marker). It is explanatory drawing (perspective view) which showed the partial structure of the card supply and conveyance part in the marking device for cards of this invention. It is explanatory drawing (front view) which showed the partial structure of the card supply and conveyance part in the marking device for cards of this invention. It is explanatory drawing (side view) which showed the principal part of the card supply and conveyance part in the marking device for cards of this invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same reference numerals in different drawings indicate parts having the same function, and repeated description in each drawing will be omitted as appropriate.

  In FIG. 1, a laser marker as the card marking device 1 will be described. The card marking device 1 includes a marking head 2 composed of a laser unit, and a card supply / conveyance unit 3 that supplies and conveys a card W at a marking position M by the marking head 2.

  The marking head 2 includes a laser light source that irradiates the marking position M with the laser light L, a scanner device (galvanomirror), a laser irradiation optical system, and the like. The card supply / conveyance unit 3 is provided with a card supply unit 3A that supplies a plurality of cards W stacked one by one, and a card conveyance unit 3B that conveys the supplied cards W. .

  In the illustrated example, the card W supplied from the card supply unit 3A is provided with a transport path switching unit 3A1, where the path is switched and sent to the information reading unit 4 once. Therefore, the information on the card W is read by the imaging unit 5 and the information is sent to the control unit 6. The information of each card W sent to the control unit 6 is sent to the marking head 2, and the marking head 2 performs a marking process according to the information of each card W. The card W sent to the information reading unit 4 is returned to the transport path switching unit 3A1 after reading the information, and is sent to the marking position M therefrom. The marking head 2 performs a marking process on the surface of the card W sent to the marking position M according to information on the card.

  2 to 4 show configuration examples of the roller transport mechanism in the card supply / transport unit 3. The roller transport mechanism 10 includes a driving roller 11 and a driven roller 12. The driving side roller 11 is a roller that is rotationally driven by transmitting the driving force of the motor 13, and the driven side roller 12 is a roller that is driven to rotate as the card W is conveyed.

  A detailed example of the roller transport mechanism 10 will be described with reference to the drawings. The roller transport mechanism 10 includes a frame body 20. A motor 13 is mounted on the side wall of the frame 20. The rotation of the motor 13 is transmitted to the drive shaft 11A of the drive roller 11 via the pulley 21. The drive shaft 11A is pivotally supported on the side wall of the frame 20 via a bearing.

  The frame body 20 is provided with a support base 22 on the drive shaft 11 </ b> A, and a card guide frame 23 for guiding the card W is attached to the support base 22. The frame 20 supports the driven roller support portion 24 so that the driven roller 12 is positioned on the driving roller 11.

  The driven roller support portion 24 includes a shaft support bracket 24 </ b> A and supports the rotating shaft 12 </ b> A of the driven roller 12. The pivot bracket 24A pivotally supports the rotary shaft 12A so as to be movable up and down. The rotating shaft 12A is provided with a roller bracket 24B, and a spring 24C is provided so as to elastically press the roller bracket 24B. Thus, the driven roller 12 can move upward (in the direction in which the gap S becomes wider) against the elasticity of the spring 24C from the illustrated lowermost limit position. An appropriate pressure can be applied when the card W is conveyed.

  Both the driving roller 11 and the driven roller 12 are constituted by rubber rollers. Specifically, a urethane rubber roller is used. By using both the driving roller 11 and the driven roller 12 as rubber rollers in this way, it is possible to prevent the roller surface from being damaged even when a card W with burrs is conveyed. Accordingly, the card W can be transported without damaging the surface of the card W itself, and the drawing disturbance marked on the surface of the card W can be eliminated.

  Further, as shown in FIG. 4, the driving roller 11 and the driven roller 12 are arranged such that adjacent outer peripheral surfaces are spaced apart by an interval S, which is larger than the thickness of the card W being conveyed. It is set small. Thus, by arranging the driving roller 11 and the driven roller 12 at an interval, it is possible to prevent the deformation of the roller that occurs when they are always in contact. Thereby, the card | curd W can be conveyed with the stable conveyance speed.

  As described above, the embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to these embodiments, and the design can be changed without departing from the scope of the present invention. Is included in the present invention. In addition, the above-described embodiments can be combined by utilizing each other's technology as long as there is no particular contradiction or problem in the purpose and configuration.
