The pair of attachment portions 113 and 115 are provided with bent portions 119 and 121 at their root portions so that their surfaces are positioned above the surface of the first guide member 110 by a predetermined dimension. The bent portions 119 and 121 are formed by bending at a right angle in the opposite direction twice in a staircase pattern.

  The second guide member 150 is made of a metal plate and is formed in an elongated flat plate shape. A bar insertion portion 151 that is recessed in a substantially U shape is formed in the center of the side on the distal end side of the second guide member 150, and the central portion of the base side of the rod insertion portion 151 is substantially circular and has the above-mentioned protection. A cover portion exposed portion 153 that exposes the entire cover portion 41 of the cover 40 is formed, and a lever that exposes the entire lever portion 43 of the protective cover 40 in the form of an elongated slit at the base side central portion of the cover portion exposed portion 153. A partial exposed portion 155 is formed. The cover portion exposed portion 153 and the lever portion exposed portion 155 are collectively referred to as a protective cover exposed portion 157. Furthermore, at a position facing the pair of screw insertion holes 15 of the grip portion 10 of the second guide member 150 and a position facing the pair of screw insertion holes 117 of the mounting portions 113 and 115 of the first guide member 110, respectively. A screw screw hole 159 made of a screw hole is formed. The bar insert portion 151 has a dimensional shape that accepts the diameters of various coins so that bar bars of various coins can be inserted.

  The convex forming member 170 is formed by forming a metal material into a cylindrical thin plate shape. A screw screw hole 171 formed of a screw hole is formed at the center of the convex portion forming member 170.

  In order to assemble the bar opening device 1, for example, in FIG. 3, first, the convex forming member 170 is first placed in the center of the upper surface of the first guide member 110 in advance, and the first guide member 110 is placed from the lower surface side of the first guide member 110. The screw 191 is inserted into the screw insertion hole 117 at the center of 110 and screwed into the screw screw hole 171 of the convex forming member 170 to integrate them. As a result, a convex portion is formed at the center of the upper surface of the first guide member 110.

  Next, the second guide member 150 is placed on the upper surface of the cutter unit 70, and the screws 193 are inserted into the two screw insertion holes 15 from the lower surface side of the cutter unit 70, so that each screw screw hole 159 of the second guide member 150 is inserted. And screw them together.

  Then, the first guide member 110 is disposed on the lower surface side of the cutter mounting portion 30 of the cutter portion 70, and the upper surfaces of the pair of mounting portions 113 and 115 of the first guide member 110 are in contact with the lower surface of the second guide member 150. The screw insertion holes 117 of the mounting portions 113 and 115 are aligned with the positions of the pair of screw screw holes 159 of the second guide member 150, and screws are inserted into the two screw insertion holes 117 from the lower surface side of the first guide member 110. 195 is inserted and screwed into each screw screw hole 159 of the second guide member 150 to integrate them. Thereby, the bar opening device 1 is completed. The above assembling procedure is an example, and it goes without saying that the assembly may be performed using other various assembling procedures.

  The bar opening device 1 configured as described above includes, for example, as shown in FIGS. 3 and 6, a gripping portion 10, a first guide member 110 installed at a longitudinal end portion of the gripping portion 10, The rotary blade 31 is installed parallel to the first guide member 110 while maintaining a predetermined distance from the upper surface of the first guide member 110, and the second guide member 150 is arranged on the rotary blade 31. ing. A gap formed between the first guide member 110 and the rotary blade 31 and a portion in front of the gap (up to the outer peripheral surface of the convex portion forming member 170) are defined as a holding portion S. A gap dimension (height dimension) between the first guide member 110 forming a part of the holding part S and the rotary blade 31 is slightly smaller than a diameter dimension of the curled part 203 of the bar 200 described below. ing.

  In order to open the bar 200 using the bar opening device 1, as shown in FIG. 7, first, one end of the bar 200 is inserted into the second guide member 150 of the bar opening device 1. Inserted into the portion 151, the one end surface of the bar 200 is brought into contact with the upper surface of the first guide member 110 (including the upper surface of the convex forming member 170). Here, as described above, the bar metal 200 wraps the stacked coins with the packaging body 201 formed of a sheet material (synthetic resin film, paper, etc.), and shows both end portions (only one end side in FIG. 7). ) Inwardly to form a curled portion 203.

  For this reason, at one end of the bar 200, the surface of the coin exposed inside the curled portion 203 comes into contact with the front end surface of the convex portion (convex portion forming member 170), and at the same time, the curled portion 203 is the convex portion. It is located at a position that surrounds the outer periphery and is in light contact with the surface of the first guide member 110 (or slightly away from the surface).

  Then, the finger 300 is inserted into the finger insertion portion 111 of the first guide member 110, and the outer peripheral surface of the bar metal 200 is pressed in the direction of the rotary blade 31 with a predetermined force. The cutting edge of the rotary blade 31 is pressed against the surface (upper part of the curled portion 203).

  And if the upper part of the bar 200 is grasped by hand and rotated, the rotary blade 31 rotates in the direction opposite to the rotation direction of the bar 200, and at the same time, the package 201 is cut in a circumferential shape. When the bar 200 is rotated once, the curled portion 203 is cut from the upper packaging body 201, and the packaging body 201 is opened.

  Then, as shown in FIG. 8, the opened bar metal 200 is removed leaving the cut curled portion 203 on the first guide member 110. A part of the cut curled portion 203 enters a gap between the rotary blade 31 in the holding portion S and the first guide member 110. Since the gap is slightly narrower than the diameter of the curled portion 203 as described above, the curled portion 203 is sandwiched. Particularly in this example, since the bar 300 is pressed against the rotary blade 31 by the finger 300 in the cutting step, a force that enters the gap is also applied to the curled portion 203. Therefore, only the cutting step is performed. A part of the curled portion 203 smoothly enters the gap and is clamped. Accordingly, the curled portion 203 that has been cut off is securely held by the bar opening device 1.

  As described above, according to the bar opening device 1, it is possible to easily cut the bar metal packaging 201 of various types of money by simply rotating the one end surface of the bar 200 in contact with the first guide member 110. Since the curled portion 203 (chips) of the package 201 generated when the package 201 is opened at the same time can be held, the curled portion 203 that has been cut off is mixed into the change machine together with the coins that have been separated. Etc. can be reliably prevented. As a result, the trouble that the chips of the package 203 are mixed in the change machine and the coins are clogged when the change is dispensed does not occur. In particular, the curled portion 203 has substantially the same height in various money types of metal bars and has a predetermined rigidity. Therefore, the curled portion 203 can be cut and held in the holding portion S, so that various It is possible to easily and surely hold the curled portion 203 cut out of a different money type bar.

  Further, during the cutting step, the first guide member 110 is provided with a convex portion by the convex portion forming member 170, so the curled portion 203 of the package 201 is positioned at a position surrounding the outer periphery of the convex portion. It can be floated from the surface of the guide member 110 (or brought into contact with the upper surface of the first guide member 110 with a weak force). Thereby, the bar 200 can be easily rotated, and the package 201 can be easily cut.

  When cutting the package 201, as described above, the bar 300 is pressed with the finger 300 and the outer peripheral surface is pressed against the rotary blade 31, so that the package 201 can be easily and smoothly cut from this point.

  Further, the second guide member 150 performs positioning in the plane direction (horizontal direction) orthogonal to the longitudinal direction of the bar metal 200, and the first guide member 110 performs positioning in the longitudinal direction (vertical direction) of the bar metal 200. Therefore, positioning of the bar 200 with respect to the rotary blade 31 can be performed easily and accurately, and the unsealing of the bar 200 and the holding of the cut curled portion 203 can be reliably performed.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea described in the claims and the specification and drawings. Is possible. Note that any shape, structure, or material not directly described in the specification and drawings is within the scope of the technical idea of the present invention as long as the effects and advantages of the present invention are exhibited. For example, in the bar opening device 1, the guide member 100 is configured by the first guide member 110, the second guide member 150, and the convex portion forming member 170, but the convex portion forming member 170 may be omitted, or the second The guide member 150 may be omitted. That is, the first guide member 110 alone can abut the one end surface of the bar 200 to make a positioning guide in the longitudinal direction of the bar 200, and by rotating this, the package 201 can be cut by the rotary blade 31, Further, a holding portion S that sandwiches the curled portion 203 between the rotary blade 31 and the first guide member 110 can also be formed.

  Moreover, in the said bar metal opening apparatus 1, although the rotary blade 31 was used as a cutter, this invention is not limited to this, You may use the fixed blade which does not rotate. Even if a fixed blade is used, the package 201 can be cut by rotating the bar 200 that touches the fixed blade. The structure of the cutter mounting portion 30 can be variously modified. In short, any structure may be used as long as the cutter is installed at a predetermined distance from the first guide member 110.

  Further, the gap between the first guide member 110 and the rotary blade 31 constituting a part of the holding portion S is not necessarily narrower than the thickness of the cut curled portion 203. In this case, the curled portion 203 cannot be sandwiched in the gap, but can be placed and held. In addition, by setting a narrow gap between the cutting edge of the rotary blade 31 and the outer periphery of the convex portion forming member 170, the curled portion 203 can be held between the gap portions.

  In the bar opening device 1, the convex portion is formed by attaching the convex portion forming member 170 to the first guide member 110. However, the convex portion is formed by bending the first guide member 110 itself. May be.

  In the bar opening device 1, the first and second guide members 110 and 150 and the convex portion forming member 170 are made of metal, but may be made of synthetic resin. The member made of synthetic resin in the above example may be made of metal.

  Moreover, although what was carried and carried in the embodiment of the bar opening device 1 of the present invention was shown, the present invention is not limited to this, and it is a base material part that can be installed in the apparatus instead of the grip part 10.
