Description

  The present invention relates to, for example, a medium transport apparatus that transfers and transports a bundle of a predetermined number of sheets and sealed with a small band between first and second transport mechanisms having a height difference.

  In this type of medium transport apparatus, a lift conveyed in the horizontal direction by the first transport mechanism is received by the lifter mechanism at the receiving position, and the received grip is vertically lifted by the lifter mechanism. There are some which transfer to the second transport mechanism.

  By the way, the lifter mechanism has a mounting plate for mounting the handle, and the mounting plate is moved to the receiving position by the driving mechanism to receive the handle conveyed by the first transport mechanism. After that, there is one that raises to the delivery position and delivers the handle to the second transport mechanism at this delivery position.

Further, two mounting plates are arranged symmetrically on the belt that runs endlessly, and one of the mounting plates is moved to the receiving position by running the belt to receive the handle conveyed by the first conveying mechanism. After that, the handle is raised to the delivery position, and at this delivery position, the handle is delivered to the second transport mechanism. After this delivery, the belt is run again to move the other mounting plate to the delivery position, and the first delivery mechanism is moved to the first delivery mechanism. There is one that receives a bundle conveyed by a conveyance mechanism (see, for example, Patent Document 1).

  However, in the former case, since there is only one mounting plate, after reaching the delivery position and delivering the bundle, it is necessary to return from the delivery position to the receiving position in order to receive the next bundle, There is a problem that it takes time.

  In the latter case, when one of the mounting plates reaches the delivery position, the other mounting plate does not reach the receiving position. The other mounting plate must be moved to the receiving position. For this reason, it is necessary to rotate the belt by an amount corresponding to the position adjustment of the mounting plate, which takes time.

  In addition, both of the two grips can be held on the mounting plate, and the subsequent grips are retained on the mechanism before passing the grips to the delivery mechanism, that is, the first transport mechanism.

  The present invention has been made paying attention to the above circumstances, and an object of the present invention is to provide a medium transport apparatus capable of simultaneously delivering a medium at a delivery position and receiving it at the receipt position. .

In order to solve the above-described problem, the first aspect of the present invention provides a first transport unit that transports a medium in a horizontal direction, a medium transported by the first transport unit, and receives the medium at a receiving position. Transfer means for moving in the vertical direction and transferring to the delivery position; and extrusion means for extruding the medium transferred to the delivery position by the transfer means in a direction perpendicular to the transfer direction of the medium;
Second conveying means for receiving and conveying the medium pushed out by the extruding means, and the transfer means is arranged to travel endlessly and to the traveling member at a predetermined interval in the traveling direction. And a plurality of placement units that receive and place the medium at the receiving position, and when one of the plurality of placement units reaches the delivery position, another placement unit is provided. One of the placement units is arranged to reach the receiving position.

  According to the present invention, the delivery at the delivery position of the medium and the receipt at the receipt position can be performed simultaneously, and the processing efficiency of the delivery of the medium can be improved.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a schematic configuration diagram showing a paper sheet processing apparatus according to an embodiment of the present invention.

  In the figure, reference numeral 1 denotes an apparatus main body, and a loading unit 2 for loading sheets in a stacked state is provided on one side of the apparatus main body 1. The sheets fed into the loading unit 2 are taken out one by one by the take-out unit 3, and the taken-out sheets are conveyed along the conveyance path.

  In the conveyance path, detection units 4 and 5, a plurality of regular paper accumulation units 7, an audit (inspection) accumulation unit 13, and an exclusion paper accumulation unit 14 are sequentially arranged along the conveyance direction of the sheets. .

  Hundred strip hanging sections 8 are respectively disposed on the lower side of the plurality of regular paper stacking sections 7 and the audit (testing) stacking section 13. The hundred-sheet belt-hanging portion 8 binds hundred sheets of paper sheets together with a small band to form a bundle as a medium. A transport conveyor 16 as a first transport means for transporting the handle in the direction of the arrow A1 is provided on the lower side of the hundred-sheet belt hanging portion 8, and the handle is received and raised on the unloading end side of the transport conveyor 16. A lifter mechanism 17 is provided as a transfer means. The handle lifted by the lifter mechanism 17 is pushed out onto a transfer table 18 as a second transfer means by a sweeper 33 as an extruding means described later. On the upper side of the transport table 18, a label attaching unit 11 for attaching a label to a handle and a bar code reader 12 for reading information on the label are arranged.

  In the above-described configuration, the 1000 sheets stacked in the feeding unit 2 are taken out one by one by the taking-out unit 3. The paper sheets are transported along the transport path, counted by the detection units 4 and 5, printed, read, and determined by various detection functions. The paper sheets are classified based on the determination result, and the normal determination papers are continuously stacked on the regular paper stacking unit 7. Each band is wrapped and sealed to become a handle.

  A bundle of hundred sheets is transferred onto the conveyor 16 and conveyed, and then lifted through the lifter mechanism 17 and pushed onto the conveyor table 18. A label on which information is printed by the label sticking portion 11 is attached to the extruded handle, and the label is read out by a barcode reader and then discharged to the outside. Further, the paper sheets determined to be abnormal by the detection unit 5 are accumulated in the rejection ticket accumulating unit 14.

  FIG. 2 is a perspective view showing the lifter mechanism 17 described above, and FIG. 3 is a side view thereof.

  The lifter mechanism 17 has two lifter belts 21 as traveling members that are arranged in parallel and perpendicularly with a predetermined interval, and these lifter belts 21 are stretched between a driving pulley 22 and a driven pulley 23. The vehicle travels endlessly along the direction of the arrow A2. Mounted on the lifter belts 21 are a plurality of (for example, nine) placement plates 25a to 25i at equal intervals in the running direction.

  The upper end side of the lifter belt 21 is the delivery position A for the handle t, and the lower end side is the receiving position B for the handle t. For example, when the placement plate 25a reaches the upper end delivery position A due to the travel of the lifter belt 21, the placement plate 25e reaches the lower end delivery position B. Thereafter, the placement plate 25b reaches the upper end delivery position A. When the position A is reached, the mounting plate is simultaneously positioned at the delivery position A and the receiving position B such that the mounting plate 25f reaches the receiving position B at the lower end.

  FIG. 4 shows a detection sensor for detecting the presence or absence of a handle placed on a placement plate disposed on the front surface side of the lifter mechanism 17.

  The detection sensor 27 includes a light emitting element 28 and a light receiving element 29, and light emitted from the light emitting element 28 is received by the light receiving element 29 through an opening 30 formed in the mounting plate 25 a (˜25 i). It has come to be. The presence or absence of a handle on the mounting plate is determined depending on whether or not the light receiving element 29 receives light.

  FIG. 5 shows a sweeper 33 as an extruding means provided in the delivery part of the small bundle t.

  The sweeper 33 is reciprocated in a direction perpendicular to the ascending / descending direction of the mounting plate 25a (to 25i) by a driving mechanism (not shown), and the handle on the mounting plate 25a (to 25i) is transferred from the mounting plate to the transfer table 18. It is designed to push upward.

  Next, the operation of the lifter mechanism 17 configured as described above will be described.

  The small bundle t discharged from the hundred-sheet band hanging portion 8 is placed on the conveyor 16 and conveyed. As shown in FIG. 2, the small bundle t is discharged from the transport conveyor 16 and transferred to the mounting plate at the lower end of the lifter mechanism 17. When there is this transfer, the lifter belt 21 travels upward and the handle t is transferred to the delivery position A at the upper end. At this time, assuming that the mounting plate 25a (shown in FIG. 3) located at the delivery position A is the first sheet, the fifth mounting plate 25e installed on the front surface is positioned at the lower receiving position B.

  From this state, the sweeper 33 of the sweeper 33 is advanced to push out the handle t on the mounting plate 25a at the delivery position A and transfer it onto the transport table 18. At this time, if there is a subsequent handle t ejected from the hundred-piece band hanging portion 8, it is placed on the conveyor 16 and conveyed, and is transferred onto the lower mounting plate 25e at the receiving position B. It will be posted.

  If the bundle t is not discharged from the hundred-sheet belt section 8, it stops and waits until it is ejected from the hundred-sheet band section 8, and if it is ejected from the hundred-sheet band section 8, the discharged bundle Is transferred by the transfer conveyor 16 and transferred onto the mounting plate 25e at the receiving position B at the lower end.

  The grip t transferred onto the mounting plate 25e is transferred to the delivery position A at the upper end in the same manner as described above, and is transferred onto the transfer table 18 by being pushed out by the sweeper 33. Thereafter, the same operation is sequentially repeated.

  In addition, when the discharge interval of the small bundles t discharged from the 100-sheet belt hanging portion 8 is short, there is a possibility that the small bundles may stay on the conveyor 16. In this case, the lifter mechanism 17 can hold a plurality of grips t by placing the grips t on the respective mounting plates 25i to 25e on the front surface. That is, the lifter mechanism 17 is not lifted continuously from the lower end to the upper end, but is lifted and stopped every one or two mounting plates, and the grip t discharged from the hundred-sheet belt portion 8 at this stop is If there is, a handle is placed on the mounting plate at the lower end by the transfer conveyor 16 and raised again. By repeating this, it is possible to convey the lifter mechanism 17 while holding a plurality of grips.

  At this time, it is also possible to select the rising width of the mounting plate by detecting the presence or absence of a handle using the detection sensor 27 installed on each mounting plate.

  Further, in the present invention, nine mounting plates are provided on the lifter belt 21, but the mounting plates can be increased or decreased according to the height difference.

  As described above, according to this embodiment, it is possible to simultaneously deliver and receive a bundle between conveying mechanisms having different elevations, and to shorten the conveying time.

  Further, a plurality of small bundles can be held on the lifter mechanism 17, and the small bundles can be prevented from staying on the conveyor 16.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments.
