Description

  The present invention relates to a roller cleaning mechanism of a medium processing apparatus that feeds paper sheets by a roller or the like and performs predetermined processing.

  In general, in media processing processing for handling media such as banknotes, a banknote which is set by a customer in a stacking manner at a take-out port is fed out by a feeding roller, taken in by a gate roller, separated by a separation roller, and a banknote is processed one by one. It is transported inside.

  Because of this take-in operation, the number of banknotes to be taken in a day is several thousand. Therefore, part of the material of the medium at the time of take-in and dirt adhered on the medium adhere to the gate roller. In some cases, poor media uptake may occur. For this reason, maintenance personnel regularly clean this dirt.

  Alternatively, in order to eliminate the cleaning work by the maintenance staff, the cleaning roller is periodically pressed against the gate roller to remove the dirt (for example, see Patent Document 1).

Alternatively, in electrophotographic printers, copiers, and the like, there is a technique for removing the unnecessary toner by pressing a cleaning roller against the drum every predetermined time in order to remove unnecessary toner attached to the drum. (For example, see Patent Document 2).

(Step S1). In addition, the clip portion 14 shown in FIG. 2 is normally in a state in which the rubber tube 13 is pressed by a spring or the like (not shown) and the rubber tube 13 is closed (step S2).

  As in the first embodiment, for example, when the number of bills to be fed out is equal to or more than a predetermined number (for example, 10,000) by the passage number / time detection unit 10d, or the accumulated time required for the feeding is a predetermined time (for example, 1 week) or more, or when the slip monitoring unit 10a or the transit time monitoring unit 10c extracts the slip generated due to the dust from the feeding time, the transport time, and the moving distance, and becomes a predetermined value or more. It is determined that cleaning is necessary (step S3).

  When it is determined that cleaning is necessary, the opening / closing drive unit 17 is activated, the clip unit 14 is pulled, and the rubber tube 13 is opened (step S4). Then, the cleaning liquid in the cleaning liquid container 21 flows out from the opened rubber tube 13, passes through the tube 15, and begins to adhere to the cleaning roller 6.

  Then, after the cleaning liquid is adhered to the cleaning roller 6 for a predetermined time, when the activation of the opening / closing drive section 17 is stopped, the clip section 14 is pushed by a spring or the like (not shown), the rubber tube 13 is closed, and the cleaning liquid flows out. Stop (step S5). At this time, the cleaning roller 6 is preferably attached while being rotated by a motor or the like (not shown) as in the first embodiment.

  Then, in order to press the cleaning roller 6 against the gate roller 3, the rotation driving unit 16 is driven and rotated in the direction of arrow E at the fulcrum b to raise the cleaning roller unit 6 (step S6). This state is the state of the solid line in FIG.

  Then, when the gate roller 3 is idled, the cleaning roller 6 rotates together to clean the gate roller 3 (step S7). At this time, instead of rotating the cleaning roller 6 together with the gate roller 3, it can be efficiently cleaned by rotating the gate roller 3 while rotating slowly or faster than the gate roller 3 or in the opposite direction. The same as in the first embodiment.

  Then, after performing the cleaning operation for a predetermined time, the operation control unit 9 returns the cleaning roller 6 to the direction opposite to the E direction and separates it from the gate roller 3 to complete the cleaning operation (step S8).

  In the above description, it has been described that the cleaning liquid does not adhere when the cleaning roller 6 is in contact with the gate roller 3 and cleaning is performed. However, in order to further improve the cleaning effect, the position of the tube 15 can be moved upward. Thus, the cleaning liquid may be adhered even during the cleaning operation.

(Effect of Example 2)
As described in detail above, according to the roller cleaning mechanism of the medium storage device of the second embodiment, the cleaning liquid is attached to the cleaning roller 6 by using a tube instead of spraying the cleaning liquid. There is no need to provide a cleaning liquid container with high sealing performance, and the roller can be efficiently cleaned with an inexpensive configuration.
