Description

  The present invention relates to a processing device for paper sheets such as securities, and more particularly to a sealing device for sealing paper sheets.

  A paper sheet processing apparatus that processes paper sheets such as securities takes out paper sheets one by one from a paper sheet (for example, 1000 sheets) input in a batch according to the processing unit. The paper sheet is discriminated and the quality (shape, damage, etc.) of the paper sheet is determined by a paper sheet discriminating device, and a normal ticket (hereinafter referred to as a regular ticket), a defective ticket (hereinafter referred to as a non-performing ticket), and When it is classified into an exclusion ticket such as a transport abnormality ticket or a two-sheet pick-up ticket, and is primarily collected by the accumulating device, and the number of the bundle of paper sheets primarily accumulated reaches a predetermined number (for example, 100), This is an apparatus for forming a bundle H by binding (sealing) with a binding device (sealing device) using a binding belt (band) such as a paper belt.

  In the sealing device, at the time of sealing, the band can obtain a banding force with respect to the handle by winding the band in a state where the handle is bent in the longitudinal direction. If this curvature is not uniform over the entire length, the banding becomes unstable or the band of the finished handle is displaced.

  FIG. 1A is a perspective view of a portion that curves the sheet bundle 8 of the sealing device according to the first embodiment of the present invention. FIG. 1 (2) is a side view of the main part of FIG. 1 (1).

  In the present embodiment, an auxiliary mechanism for assisting bending is provided not only on the longitudinal direction rear side of the sheet bundle 8 used conventionally but also on the front side in the longitudinal direction. I do.

  The curved portion of the paper sheet bundle 8 is provided with a carver device 1 that receives the lower surface of the paper sheet bundle 8 conveyed in the longitudinal direction and promotes the curving, and the paper sheet bundle 8 placed on the carver device 1. The upper surface of the sealing position is pressed toward the carver device 1 to come into contact with the sweeper device 2 that curves the paper sheet bundle 8 and the belt wound around the sealing position, and the movement of the belt stops and the paper A clamper device 10 is provided to prevent the paper sheets constituting the leaf bundle 8 from being rampant.

  The carver device 1 is composed of two supporting members that support both longitudinal end faces of the sheet bundle 8 from below so that the placement surface on which the sheet bundle is placed has a recess in the longitudinal direction. The tip of the support material is bent in a V shape inside to form a curve of the sheet bundle 8 and prevent the sheet bundle 8 from falling.

  The sweeper device 2 moves (sweeps) to the sealing position of the paper sheet bundle 8 placed on the carver device 1, presses the upper surface of the paper sheet bundle 8 toward the carver device 1, and Curve the sheet bundle.

  The clamper device 10 is provided with a clamper 5, an arm 6 and a pusher 7 for pressing the sheet bundle 8, and a clamper shaft 51b provided at the end of the clamper 5 is connected to the link mechanism 4 that performs a rotational motion. By being linked and driving the link mechanism 4, it is possible to perform a rectilinear motion or a rotational motion that can freely move forward and backward with respect to the clamper 5. As a result, it comes into contact with the band wound at the sealing position, and the movement of the band stops.

  Further, the arm 6 is moved by the rotation of the link mechanism 4, and the pusher 7 having the auxiliary protrusion 71 that assists the bending of the sheet bundle 8 functions.

  The rotation center 42 of the link mechanism 4 is fixed to the rotation shaft 31 of the drive motor 3 as drive means, and the link mechanism 4 is driven as the drive motor 3 rotates to assist the clamper 5 and the pusher 7. The protrusion 71 is operated. Hereinafter, the structure of each part which comprises the said clamper apparatus 10 is demonstrated.

  FIG. 2 is a detailed view of the link mechanism 4. FIG. 3 is a detailed view of the clamper 5. FIG. 4 is a detailed view of the arm 6. FIG. 5 is a detailed view of the pusher 7.

  The link mechanism 4 includes a groove 41 for sliding a component connected to the link mechanism 4 and a shaft 42 incorporated in the groove 41 for attaching other components. A clamper 5 described later is attached to the shaft 42.

  The clamper 5 has a clamper main body 51, and a rail 52 and a pusher holder 53 are arranged on the clamper main body 51.

  The clamper body 51 is provided with a pressing surface 51a for preventing the bundle shape of the sheet bundle 8 from being disturbed, and a clamper shaft 51b disposed at the end of the body. The clamper shaft 51b is incorporated in the shaft 42 of the link mechanism 4 and can slide in the groove 41.

  The rail 52 is configured in a plate state and is arranged in the moving direction of the clamper 5. The arm 6 is incorporated in the rail 52.

  The arm 6 has a rod state, and in this rod state, a pair of rotating bodies 62 and 62 disposed opposite to each other so as to sandwich the rail, a protrusion 63 provided at the other end, A pivotal fulcrum 61 provided in the section is provided. The rail 62 is sandwiched between a pair of rotating bodies 62 and 62 of the arm 6. The fulcrum 61 is rotatably fixed to a base (not shown) that fixes the clamper device 10. With this configuration, the arm 6 moves along the rail 52 in the direction of the arrow 54 according to the rotational movement of the link mechanism 4.

  The pusher holder 53 is provided with a pusher shaft 53a for rotatably mounting the pusher 7 and a protrusion 53b for restricting the operation of the auxiliary protrusion 71 of the pusher 7.

  The pusher 7 is provided with an auxiliary protrusion 71 that presses the sheet bundle 8, a protrusion 72 that is hooked to the rotating bodies 62 and 62 of the arm 6, and a shaft 73 that is a fulcrum incorporated into the pusher shaft 53 a. It is biased in the direction by a spring force (not shown).

  6-10 is a figure explaining the operation | movement of the bending part comprised from the components mentioned above later on.

  A bundle of paper sheets (100 sheets of paper sheets) 8 is stacked on the carver apparatus 1.1 (FIG. 6).

  The accumulated sheet bundle 8 is pressed and curved from the upper surface of the sheet bundle 8 by the sweeper 2 (FIG. 7).

  When the drive motor 3 is driven, the link mechanism 4 pivotally supported on the motor shaft 31 of the drive motor 3 rotates in the counterclockwise direction indicated by an arrow 44 in the figure.

  At this time, by the operation of the link mechanism 4, the clamper 5 starts a linear motion in the direction of the sheet bundle 8 and approaches the sheet bundle 8.

  Further, since the rotating bodies 62 and 62 of the arm 6 sandwich the rail 52 of the clamper 5, the arm 6 starts to rotate counterclockwise around the fulcrum 61.

  At this time, the pusher 7 pivotally supported by the pusher holder shaft 53a of the clamper 5 approaches the sheet bundle 8 together (FIG. 8).

  When the link mechanism 4 continues to rotate, the arm protrusion 63 rides on the rotating body 43 of the link mechanism 4. As a result, the clamper 5 is subjected to rotational motion in addition to linear motion. In addition, when the arm protrusion 63 rides on the rotating body 43, a pressing force for pressing the sheet bundle 8 is defined. The escape of the pressing force when the thickness of the sheet bundle 8 is different can be absorbed by the protrusion 72 of the spring-like body.

  Simultaneously with the above operation, the protrusion 72 of the pusher 7 rides on the rotating body 62 of the arm 6. As a result, the pusher 7 leaves the protrusion 53b of the pusher holder 53 of the clamper 5, and eventually the auxiliary protrusion 71 that presses the sheet bundle 8 from the pressing surface 51a appears (FIG. 9).

  When the clamper 5 reaches the operating position in this way, the pressing surface 51 of the clamper 5 presses the upper surface of the sheet bundle 8. At the same time, the protrusion 72 performs an auxiliary function of bending by pressing downward from the upper surface of the sheet bundle 8 (FIG. 10).

As described above, the sheet bundle 8 made of 100 sheets is placed on the carver apparatus 1. The paper sheet bundle 8 is bent by the sweeper 2 protruding from the right side in the drawing to the sealing position, descending from the illustrated position, and pressing the paper sheet bundle 8. In this state, the paper band K is wound around the sheet bundle 8 at the illustrated position, and the upper end portion thereof is thermally bonded with a heater (not illustrated). Various methods for winding the paper band K around the paper sheet bundle 8 and thermal bonding methods are known and can be achieved by the conventional technique, and thus the description thereof is omitted.

  FIG. 12 is a schematic diagram showing the positional relationship of the carver device 1, the sweeper device 2, the clamper 5, and the pusher 7 with respect to the band position of the sheet bundle 8 in the sealing device of the first embodiment. In the present embodiment, the pressing position of the pusher 7 is set in the vicinity of the front end portion 1 a of the carver device 1. The height of the pusher 7 is set to be approximately the same as the height of the conventional clamper 5.

  In addition, when the bill length of the sheet bundle 8 is large, a stable curving effect can be obtained by providing the auxiliary protrusion 71b in addition to the auxiliary protrusion 71a of the pusher 7. The auxiliary protrusion 71b is provided at a position near the middle between the front end 1a of the carver 1 and the tip 8a of the maximum sheet length of the sheet bundle 8.

  As described above, according to the embodiment of the present invention, by further providing an auxiliary mechanism that assists the pressing of the sheet bundle in bending deformation, the gripping shape such as a sealing failure or a band shift due to distortion of the bending is provided.
