And, in this type of coin wrapping device, when stacking coins one after the other to make a stacked coin, the stacking is stably performed by pressing the uppermost coin from above with a vertically movable pressing member, There is one that detects the accumulated height of the accumulated coins using this pressing member (for example, see Patent Document 1).
JP 2006-92188 A

  By the way, when stacking coins, it is effective for the pressing member to hold the large range of coins as much as possible to stabilize the stacking. On the other hand, since coins may have a stamp or the like and the posture may not be constant during accumulation, it is necessary to detect the height at the center as much as possible in order to eliminate the influence of this posture. In the case of performing the pressing of coins and the detection of the accumulated height using the above-described one pressing member, it has been difficult to achieve both stable accumulation and accurate detection of the accumulated height.

  Therefore, an object of the present invention is to provide a coin wrapping apparatus that can achieve both stable accumulation and accurate detection of the accumulation height.

  In order to achieve the above-mentioned object, the invention according to claim 1 includes a stacking unit that stacks coins sequentially to form a stacked coin, and a packaging unit that wraps a wrapping paper around the stacked coin to form a packed coin. In the coin wrapping machine provided, a vertically movable pressing member that presses the uppermost coin from above, and a height of the accumulated coins is detected by contacting the uppermost coin provided on the inner side of the pressing member. And a height detecting member.

  The invention according to claim 2 is the invention according to claim 1, wherein the stacking unit has an inclined lifting means for lifting the upstream side in the feeding direction of the coins fed from the side. The coins are sequentially stacked downward by repeatedly feeding the next coin from the upstream side to the lower side of the raised coin and lifting the upstream side in the feeding direction of the next coin by the inclined lifting means. In a state where the accumulated coins accumulated at the portion are supported on the lower side and separated from the inclined lifting means, the accumulated height is detected by the height detecting member, and the lower end portion of the pressing member is The height detecting member is inclined so that the upstream side in the feeding direction is located on the upper side, and the height detecting member has a lower part having a truncated cone shape with a convex downward and a flat bottom end. Yes.

  According to the first aspect of the present invention, the height detection member for detecting the height of the accumulated coins by moving the height detection member in contact with the uppermost coin on the inner side of the vertically movable pressing member that presses the uppermost coin from above is moved up and down. Since it is provided freely, a large range of coins can be pressed by the outer pressing member, and the accumulated height can be detected by contacting the center side of the coin by the inner height detection member. Therefore, both stable integration and accurate detection of the integration height can be achieved.

  According to the invention of claim 2, the stacking unit lifts the coins fed from the side upward in the feeding direction, feeds the next coin from the upstream side to the lower side of the raised coin, and feeds the next coin Since the coins are stacked one after another by repeatedly lifting the upstream side in the direction, the coins are stacked with the upstream side in the feed direction inclined at the time of stacking. By tilting so that the side is positioned on the upper side, the coin can be satisfactorily pressed from above. In addition, since the lower portion of the height detection member has a truncated cone shape that protrudes downward, it can escape well with respect to the initial coin feeding on the conical surface. Further, the accumulated height is detected by the height detection member in a state where the accumulated coins accumulated in the accumulation unit are supported on the lower side and separated from the inclined lifting means (that is, the state in which the inclination is released). The height detection member can contact the center side of the coin on the plane of the lower end and accurately detect the height.

A coin wrapping apparatus according to an embodiment of the present invention will be described below with reference to the drawings.
The coin wrapping apparatus 11 of the present embodiment shown in FIG. 1 has a rotating disk (not shown) into which coins C are put in a lump, and the coin C in the rotating disk is horizontally aligned by the centrifugal force of the rotating disk. One sheet is sent to the coin passage 12 provided.

  The coin passage 12 has a conveyor belt 13 that conveys the coins one by one in the upper position thereof. A coin discriminating section (not shown) is provided in the middle of the coin passage 12 so as to discriminate the authenticity and denomination of the coin C being conveyed. The coins C that have passed through the coin passage 12 are supplied to the stacking unit 15 and are stacked in the vertical direction by the stacking unit 15 to be stacked coins. 16 is packaged.

  The stacking unit 15 stacks the coins C one by one sequentially to form a stacked coin, and stops the coins C by abutting on the downstream in the feed direction of the coins C fed from the conveyor belt 13; An accumulation roller (inclined lifting means) 21 is provided upstream of the stopper 20 in the feeding direction of the coin C and lifts the upstream side in the feeding direction of the coin C stopped by the stopper 20.

  The accumulating roller 21 has a plurality of inclined protrusions 22 formed at equal intervals on the outer diameter side, the radius of which gradually increases along the rotation direction, so that some of the inclined protrusions 22 protrude upward from the coin passage 12. Thus, it is arranged below the coin passage 12. Then, one coin C fed horizontally from the side by the driving force of the conveyor belt 13 abuts against the abutting surface 22a along the radial direction of the one inclined protrusion 22 and pushes this, thereby pushing the stacking roller 21. The roll is rotated by a predetermined angle and stopped by the stopper 20, and the rotation of the predetermined angle causes the accumulation roller 21 to lift the upstream side in the feed direction of one coin C by the inclined surface 22b on the outer diameter side of the next inclined protrusion 22. At the same time, the contact surface 22 a of the next inclined protrusion 22 is protruded substantially perpendicularly from the coin passage 12. In this way, the next coin C is fed from the upstream side to the lower side of the one coin C in the inclined state in which the upstream side in the feeding direction is lifted from the coin passage 12 by the accumulation roller 21, and the next coin C , While sinking under one coin C, abuts against the abutting surface 22a along the radial direction of the next inclined projection 22 and pushes it to rotate the stacking roller 21 by a predetermined angle and stop at the stopper 20 As a result, the accumulation roller 21 further lifts the upstream side in the feeding direction of the next coin C by the inclined surface 22b on the outer diameter side of the next inclined projection 22 by the rotation of the predetermined angle, and the The contact surface 22a protrudes from the coin passage 12 substantially vertically. By repeating such an operation, the coins C are sequentially stacked below.

  In the present embodiment, the stacking unit 15 has a hollow pressing member 25 that can move up and down to hold the uppermost coin C from above. As shown in FIG. 2, the pressing member 25 includes a curved bending member 26 obtained by cutting a cylinder into an axial line and removing a part thereof, and a bending member 26 fixed to the inside of the upper portion of the bending member 26. And a guide 27 having a coaxial cylindrical shape. As shown in FIG. 1, the pressing member 25 is supported by the guide column 29 via a support member 28 extending radially outward, and moves up and down along the guide column 29. Here, the pressing member 25 is arranged so that the position of the central axis coincides with the substantially center of the coin C that abuts against the stopper 20, is positioned below by its own weight, and the coin C sent from the side is stopped by the stopper C When it comes into contact with 20, the coin C is pushed up. Then, when the coin C sequentially enters the bottom, it is pushed up by the rising uppermost coin C, and the coin C is pressed downward by its own weight (or its own weight and a biasing force of a spring (not shown)).

  Here, since the coins C are accumulated in an inclined state by the accumulation roller 21, the lower end surface (lower end portion) 26 a of the bending member 26 of the pressing member 25 is positioned on the upper side in the feeding direction in accordance with the inclination of the coins C. It is a flat slope.

  And the height detection member 31 which contact | abuts the uppermost coin C and detects the height of the accumulation | storage coin is provided inside the above-mentioned holding | suppressing member 25. As shown in FIG. The height detection member 31 includes a guide shaft portion 32 slidably fitted to a guide 27 in the holding member 25, and a detection shaft having a larger diameter than the guide shaft portion 32 provided coaxially with the lower end of the guide shaft portion 32. Part 33. A stopper ring 34 for preventing the stopper 27 from coming off from the guide 27 is fitted to a part of the guide shaft portion 32 of the pressing member 25 that protrudes upward from the guide 27, and the upper surface of the detection portion 33 of the height detection member 31. And a coil spring 35 that presses the height detection member 31 downward is interposed between the holding member 25 and the lower surface of the guide 27 of the pressing member 25. The spring force of the coil spring 35 is set to a relatively weak spring force that can accommodate the height detection member 31 in the pressing member 25 when the height detection member 31 is pushed up.

  The lower part of the detection unit 33 has a truncated conical shape that protrudes downward and has a flat bottom end. That is, the detection portion 33 is formed with a cylindrical surface 33a coaxial with the guide shaft portion 32 at the upper portion, a conical surface 33b coaxial with the guide shaft portion 32 and having a diameter reduced toward the lower side, and formed at the lower end. A horizontal circular planar detection surface (plane) 33c coaxial with the guide shaft portion 32 is formed.

  As described above, the height detection member 31 is provided to be movable up and down with respect to the pressing member 25.

  The stacking unit 15 has a conveyor post 38 that vertically moves up and down with respect to the coin passage 12 from a position upstream from the stopper 20, and the conveyor post 38 is in a stacked state as shown in FIG. 3. The accumulated coins CC are supported on the lower side and lifted to a predetermined packaging position separated from the accumulation roller 21 and the stopper 20.

  Above the pressing member 25 and the height detection member 31, a height detection unit 40 that abuts on the upper end portion of the height detection member 31 and detects the height position is provided. That is, when the conveyor post 38 is lifted to a predetermined packaging position as described above, the height detection member 31 that comes into contact with the accumulated coins CC accumulated on the conveyor post 38 by its own weight and the biasing force of the coil spring 35 is also lifted. Thus, the height detection unit 40 detects the accumulated height of the accumulated coins CC by detecting the height position of the upper end portion of the height detection member 31.

  The height detection unit 40 abuts on the upper end of the height detection member 31 and rotates in accordance with the height position thereof, and the height detection member 31 detects the rotation position of the detection lever 41. And a rotary encoder 42 for detecting the height position of the upper end of the encoder.

  The wrapping unit 16 wraps wrapping paper around the accumulated coins CC that are lifted up to a predetermined wrapping position by the conveyor post 38 to form wrapping coins, and is arranged around the conveyor post 38 along the vertical direction. And three parallel wrapping rollers 44 (only two are shown in FIG. 3) that can be brought close to and away from each other. The wrapping rollers 44 supply a predetermined length of wrapping paper around the accumulated coin CC and wind it A wrapping mechanism that rotates, and a crimping mechanism (not shown) that crimps the wrapped wrapping paper at the upper and lower ends of the accumulated coins CC are provided.

  In the coin wrapping apparatus 11 according to the present embodiment having the above-described configuration, when coins C are collectively put into a rotating disk (not shown) and a start operation is input, a control unit (not shown) causes the rotating disk and the conveyor belt 13 to move. Rotate. Then, the coins C in the rotating disk are fed one by one to the coin passage 12 by centrifugal force, and are conveyed by the conveyor belt 13 toward the stacking unit 15 on the coin passage 12. Then, it is discriminated and counted by a coin discriminating unit (not shown) and sent out from the conveyor belt 13 to the accumulating unit 15. Then, the first coin C comes into contact with the contact surface 22a of the inclined protrusion 22 of one of the stacking rollers 21 and pushes this, thereby rotating the stacking roller 21 by a predetermined angle and stopping at the stopper 20. By this rotation of the predetermined angle, the accumulation roller 21 lifts the upstream side in the feeding direction of the first coin C by the inclined surface 22b of the next inclined protrusion 22 to be in an inclined state. At this time, the first coin C sinks under the lower end surface 26a of the pressing member 25. At this time, the first coin C comes into contact with the conical surface 33b of the height detecting member 31 and lifts it by its inclination. Then, while pushing into the holding member 25, it goes under the detection surface 33c. In this state, the upper surface of the first coin C comes into contact with substantially the entire lower end surface 26 a of the pressing member 25. Then, the second coin C is sent from the upstream side to the lower side of the first coin C, and the second coin C sinks under the first coin C, When the abutting surface 22a of the next inclined protrusion 22 is brought into contact with and pushed, the accumulating roller 21 is rotated by a predetermined angle and stopped by the stopper 20. The upstream side in the feed direction of the second coin C is lifted by the inclined surface 22 b of the inclined protrusion 22. As a result, the first coin C is lifted in an inclined state and abuts on substantially the entire lower end surface 26 a of the pressing member 25. By repeating such an operation, as shown in FIG. 1, the coins C are sequentially stacked below.

  Then, when the last coin of the predetermined number of packaging units is detected by the coin discriminating unit, the control unit regulates the delivery of further coins to the stacking unit 15 with a sending stopper (not shown), and this last At the timing when the coin C surely enters the lowest position of the already accumulated coins C, the conveyor post 38 that has been retracted below the coin passage 12 until then is moved to a predetermined packaging position as shown in FIG. Raise. As a result, the accumulated coins CC that have been riding on the accumulation roller 21 are supported by the conveyor post 38 from below and rise together with the pressing member 25 and the height detection member 31, and leave the accumulation roller 21. By separating from the accumulation roller 21, the accumulated coin CC changes in the inclined state. However, the height detection member 31 follows the change in the inclined state by the urging force of the coil spring 35 on the detection surface 33c. And the state which contact | abutted to the center side of the uppermost coin C is maintained. Then, the upper end portion of the height detection member 31 comes into contact with and pushes up the detection lever 41, and the rotary encoder 42 is rotated.

  The control unit detects the rotational position of the rotary encoder 42 in a state where the conveyor post 38 is raised to a predetermined packaging position and stopped as described above, and if the detected position is within a preset allowable range. Then, it is determined that the accumulated height of the accumulated coins CC, that is, the number of accumulated coins, is appropriate, the wrapping paper is wound around the accumulated coins CC by the wrapping portion 16, and both ends thereof are crimped to form a wrapping coin as a storage portion or a withdrawal portion Transport to. On the other hand, if the detection position of the rotary encoder 42 is not within the preset allowable range, it is determined that the accumulated height of the accumulated coins CC, that is, the number of accumulated coins is not appropriate (that is, there was an excess or deficiency). The stacked coins are stored in another defective storage unit without packaging.

  According to the coin wrapping apparatus 11 of the present embodiment described above, the height of the accumulated coins CC is in contact with the uppermost coin C inside the vertically movable pressing member 25 that presses the uppermost coin C from above. Since the height detecting member 31 for detecting the movement is provided so as to be movable up and down, a large range of the coin C can be pressed by the outer pressing member 25, and the inner height detecting member 31 can contact the center side of the coin C. The integrated height can be detected in contact. Therefore, both stable integration and accurate detection of the integration height can be achieved.

  Further, the stacking unit 15 lifts the coin C fed from the side upward in the feeding direction, feeds the next coin C from the upstream side to the lower side of the raised coin C, and feeds the upstream side of the next coin C in the feeding direction. The coins C are stacked one after another by repeatedly lifting the coins C. Therefore, at the time of stacking, the coins C are stacked in a state where the upstream side in the feed direction is inclined. By tilting so that the upstream side is positioned on the upper side, the coin C can be favorably pressed from above. In addition, since the lower portion of the height detection member 31 has a truncated cone shape that protrudes downward, the conical surface 33b can escape upwardly with respect to the feeding of the first coin C.

  Further, the height detection member 31 detects the accumulated height in a state in which the accumulated coins CC accumulated in the accumulation unit 15 are supported on the lower side and separated from the accumulation roller 21 (that is, in a state where the inclination is released). Thus, the height can be accurately detected by the height detection member 31 coming into contact with the center side of the coin C with the detection surface 33c on the center side at the lower end. That is, as shown in FIGS. 4A and 4B, the holding member 100 also serves as a height detection member, and the lower end of the holding member 100 is inclined so as to be higher toward the upstream side in the coin feeding direction. When the surface 100a and the horizontal plane 101b at the end on the downstream side in the coin feed direction are provided, the coin C is pressed by the inclined surface 100a during accumulation, and the coin C is contacted by the horizontal plane 101b at the lowest end when detecting the height. The detection value of the accumulation height of the accumulated coins CC changes due to the change in the inclination state of the coins. On the other hand, in the present embodiment, as shown in FIGS. 4C and 4D, the height detection member 31 inside the pressing member 25 detects the height of the center side of the coin C. It is possible to suppress the change in the detected value of the accumulated height of the accumulated coins CC caused by the change in the inclination state of C.
