It is a device that stamps precious metals and other metals such as palladium, copper, lead, aluminum, and zinc.

搬送部１は、地金Ｉｎを載置する載置部１２を一端側に有し、載置部１２を移動させる機器である。そして、載置部１２は、地金Ｉｎの少なくとも二辺、少なくとも二点、又は、少なくとも一辺及び一点から選ばれるいずれかと当接可能である送り側当接部１１が表面に配設されている。具体的には、搬送部１は、搬送部１と電気的に接続された制御部４との間で各種情報の送受信を行うことにより、一端側に設けられた載置部１２に地金Ｉｎが載置されることで、載置部１２を刻印台２まで移動させる。こうして、搬送部１によって、刻印部３と干渉せずに、載置部１２に載置した地金Ｉｎを、刻印部３の下方に位置する刻印台２まで移動させることができる。また、載置部１２の一面である表面であって、載置部１２が刻印台２へ移動させられる方向とは逆方向側に設けられた送り側当接部１１は、地金Ｉｎと当接し得る部材であり、例えば、地金Ｉｎが正方形、長方形などの四角形、若しくは他の多角形状の板状等であるときには、その少なくとも二辺、少なくとも二点、又は、少なくとも一辺及び一点から選ばれるいずれかと当接可能である立方体、直方体などの多角柱形状や円柱、楕円柱などの閉曲線の柱形状、或いはそれらを組み合わせた形状を有し、若しくは、地金Ｉｎが円形、楕円形、長円形など曲線形状の板状等であるときには、その少なくとも二点と当接可能である立方体、直方体なの多角柱形状や円柱、楕円柱などの閉曲線の柱形状、或いはそれらを組み合わせた形状を有している。送り側当接部１１によって、載置部１２を移動するときに載置部１２に載置した地金Ｉｎが滑り落ちることがなく、さらに、後述するように、載置部１２が刻印台２まで移動されたときに刻印台２に設けられた受け側当接部２１と協力して、地金Ｉｎを所定位置に固定することができる。 The transport unit 1 is a device that has a mounting unit 12 on which the bullion In is placed on one end side and moves the mounting unit 12. The mounting portion 12 is provided with a feed-side contact portion 11 capable of contacting at least two sides, at least two points, or at least one side and one point of the bullion In. .. Specifically, the transport unit 1 transmits and receives various information between the transport unit 1 and the electrically connected control unit 4, so that the bullion In is attached to the mounting unit 12 provided on one end side. Is placed, the mounting portion 12 is moved to the marking stand 2. In this way, the transport unit 1 can move the bullion In placed on the mounting unit 12 to the marking table 2 located below the marking unit 3 without interfering with the marking unit 3. Further, the feed-side contact portion 11 provided on the surface opposite to the direction in which the mounting portion 12 is moved to the marking table 2 on the surface of one surface of the mounting portion 12 is in contact with the metal In. It is a member that can be in contact with each other. It has a polygonal pillar shape such as a cube or a rectangular parallelepiped that can abut on any of them, a closed curved pillar shape such as a cylinder or an elliptical pillar, or a combination of these, or the base metal In is circular, elliptical, or oval. When it is a curved plate shape, etc., it has a cube that can contact at least two points, a rectangular parallelepiped polygonal pillar shape, a cylinder, a closed curved pillar shape such as an elliptical pillar, or a shape that combines them. There is. The feed-side contact portion 11 prevents the bullion In mounted on the mounting portion 12 from slipping off when the mounting portion 12 is moved, and further, as will be described later, the mounting portion 12 reaches the marking stand 2. When moved, the bullion In can be fixed in a predetermined position in cooperation with the receiving side contact portion 21 provided on the stamping table 2.

本実施形態において、搬送部１は、アクチュエータであり、制御部４と接続されており、運搬部５であるロボットアームによって矩形板状の載置部１２に地金Ｉｎが載置され、ロボットアームが所定の位置に戻ったことを制御部４から通知されて、図５に示すように、アクチュエータの筐体から出たり入ったりすることができる棒状部１３を直線状にアクチュエータの筐体から出すことで、棒状部１３の端部に設けられた載置部１２を刻印台２へ向かって移動させる。そして、図６、図７に示すように、載置部１２に載置された地金Ｉｎが、刻印台２に設けられ平面視が略Ｌ字状の受け側当接部２１と当接し、さらに、平面視が略Ｌ字状に配設された送り側当接部１１と当接するまで、載置部１２が棒状部１３によって移動される。このとき、図７に示すように、矩形状の地金Ｉｎは、右側辺及び底辺の二辺を送り側当接部１１と当接され、左側辺及び上辺を受け側当接部２１と当接されている。さらに、棒状部１３は、所定の圧力の負荷が加わるように、受け側当接部２１に向かって押し出されるので、載置部１２に載置された地金Ｉｎは、送り側当接部１１と受け側当接部２１によって挟持されて固定される。このように、地金Ｉｎは、送り側当接部１１と受け側当接部２１によって挟持されることによって、刻印部３によって刻印されるときに動くことがないために、地金Ｉｎの表面に所定の識別表示を適切に刻印することができる。また、本実施形態のような地金Ｉｎが直方体形状などの多角柱形状のときには、送り側当接部１１は、平面視で略Ｌ字状に配設されていることが好ましい。送り側当接部１１がこのような形状であると、載置部２２に地金Ｉｎが少々傾いて載置されても送り側当接部１１及び受け側当接部２１と当接しながら方向が容易に整えられるとともに、受け側当接部２１と協力してしっかりと地金Ｉｎを固定することができる。さらに、地金Ｉｎが所定の方向に整えられやすいようにするために、図５に示すように、棒状部１３によって載置部１２が、略Ｌ字状に配設された送り側当接部１１の各辺が為す小さい角に向かって移動されることが好ましい。なお、本実施形態において、送り側当接部１１は、載置部１２の一面である表面であって、載置部１２が刻印台２へ移動させられる方向とは逆方向側に平面視で略Ｌ字状の多角柱形状に配設されているが、受け側当接部２１とで地金Ｉｎを当接することができる限りにおいて、上述したように、円柱、楕円柱などの閉曲線の柱形状、或いはその閉曲線の柱形状及び多角柱形状を組み合わせた形状としてもよい。 In the present embodiment, the transport unit 1 is an actuator and is connected to the control unit 4. The robot arm, which is the transport unit 5, mounts the metal In on the rectangular plate-shaped mounting portion 12, and the robot arm. Is notified from the control unit 4 that the robot has returned to a predetermined position, and as shown in FIG. 5, the rod-shaped portion 13 that can move in and out of the actuator housing is linearly ejected from the actuator housing. As a result, the mounting portion 12 provided at the end of the rod-shaped portion 13 is moved toward the marking table 2. Then, as shown in FIGS. 6 and 7, the bullion In mounted on the mounting portion 12 abuts on the engraving table 2 and abuts on the receiving side contact portion 21 having a substantially L-shaped plan view.

At this time, as shown in FIG. 7, the rectangular bullion In is in contact with the sending side contact portion 11 on the right side and the bottom side, and is in contact with the receiving side contact portion 21 on the left side and the upper side. Being touched. Further, since the rod-shaped portion 13 is pushed toward the receiving side contact portion 21 so that a load of a predetermined pressure is applied, the bullion In mounted on the mounting portion 12 is the feed side contact portion 11. It is sandwiched and fixed by the receiving side contact portion 21. As described above, since the bullion In is sandwiched between the sending side contact portion 11 and the receiving side contact portion 21 and does not move when engraved by the engraved portion 3, the surface of the bullion In is formed. Can be appropriately engraved with a predetermined identification mark. Further, when the bullion In has a polygonal column shape such as a rectangular parallelepiped shape as in the present embodiment, it is preferable that the feed side contact portion 11 is arranged in a substantially L shape in a plan view. When the feed-side contact portion 11 has such a shape, even if the bullion In is placed on the mounting portion 22 at a slight inclination, the direction while contacting the feed-side contact portion 11 and the receiving-side contact portion 21. Can be easily arranged, and the bullion In can be firmly fixed in cooperation with the receiving side contact portion 21. Further, as shown in FIG. 5, the mounting portion 12 is arranged in a substantially L-shape by the rod-shaped portion 13 so that the bullion In can be easily arranged in a predetermined direction. It is preferable to move toward the small corner formed by each side of 11. In addition, in this embodiment, the feed side contact portion 11 is a surface which is one surface of the mounting portion 12, and is viewed in a plan view in the direction opposite to the direction in which the mounting portion 12 is moved to the marking table 2. Although it is arranged in a substantially L-shaped polygonal column shape, it is a closed-curved column such as a cylinder or an elliptical column as described above, as long as the metal In can be contacted with the receiving side contact portion 21. The shape may be a combination of a closed curve column shape and a polygonal column shape.

刻印台２は、刻印部３により地金Ｉｎを刻印するときに、載置部１２を介して地金Ｉｎを受ける部材である。刻印台２の表面には、地金Ｉｎを載置する載置部１２が移動されたときに送り側当接部１１と当接可能である辺又は点とは異なる地金Ｉｎの少なくとも二辺、少なくとも二点、又は、少なくとも一辺及び一点から選ばれるいずれかと当接する受け側当接部２１が設けられている。具体的には、刻印台２は、角形状又は円形状の平板状の部材である。そして、受け側当接部２１は、刻印台２の表面に設けられ、地金Ｉｎが正方形、長方形などの四角形、若しくは他の多角形状の板状等であるときには、送り側当接部１１と当接可能である地金Ｉｎの辺又は点とは異なる地金Ｉｎの少なくとも二辺、少なくとも二点、又は、少なくとも一辺及び一点から選ばれるいずれかと当接可能である立方体、直方体などの多角柱形状や円柱、楕円柱などの閉曲線の柱形状、或いはそれらを組み合わせた形状を有し、又は、地金Ｉｎが円形、楕円形、長円形など曲線形状の板状等であるときには、送り側当接部１１と当接可能である地金Ｉｎの点とは異なる地金Ｉｎの少なくとも二点と当接可能である立方体、直方体なの多角柱形状や円柱、楕円柱などの閉曲線の柱形状、或いはそれらを組み合わせた形状を有している。受け側当接部２１によって、載置部１２により移動された地金Ｉｎを送り側当接部１１と協力して、地金Ｉｎを所定位置に固定することができる。このため、地金Ｉｎは、運搬部５より移動されて載置部１２に載置されたとき、又は人の手によって載置部１２に載置されたとき、刻印される正しい向きに対して少々傾いて載置されたとしても、載置部１２よって移動されると送り側当接部１１と受け側当接部２１と当接しながら刻印される正しい向きに容易に整えられるので、地金Ｉｎを載置部１２の所定の位置に厳密に載置する必要がなく、より迅速に一連の刻印作業を行うことができる。 The engraving table 2 is a member that receives the bullion In via the mounting portion 12 when the bullion In is engraved by the engraving portion 3. On the surface of the engraving table 2, at least two sides of the bullion In that are different from the sides or points that can be in contact with the feed side contact portion 11 when the mounting portion 12 on which the bullion In is placed are moved. , A receiving side contact portion 21 that abuts at least two points, or at least one side and one selected from one point is provided. Specifically, the engraving table 2 is a square or circular flat plate-shaped member. The receiving side contact portion 21 is provided on the surface of the engraving table 2, and when the base metal In is a square such as a square or a rectangular parallelepiped, or another polygonal plate shape, the receiving side contact portion 21 and the feeding side contact portion 11.

Therefore, the receiving-side abutting portion 21 shown in FIG. 12 can abut and sandwich the bullion In, which is smaller than the bullion In abuting at the receiving-side abutting portion 21 shown in FIG. 7. Further, although the feed side contact portion 11 is fixed to the mounting portion 12, if it is fixed by a screw or the like, the screw or the like can be removed and removed from the mounting portion 12. In this way, the feed-side contact portion 11 can be replaced with a feed-side contact portion 11 having a different size, and can be used corresponding to the bullions In having different sizes.

そして、第三実施形態における搬送部１と載置部２について示した図１３に示すように、送り側当接部１１は、地金Ｉｎの相異なる二辺上の二点と当接可能な配置にて載置部１２に固設されており、受け側当接部２１は、送り側当接部１１と当接する二辺上の点とは異なる他の相異なる二辺上の二点と当接可能な配置にて刻印台２に固設されている。このため、第三実施形態は、第一実施形態及び第二実施形態と同様に、地金Ｉｎは、載置部１２よって移動されると送り側当接部１１と受け側当接部２１と当接しながら刻印される正しい向きに容易に整えられるという作用効果を奏する。 Then, as shown in FIG. 13 showing the transport portion 1 and the mounting portion 2 in the third embodiment, the feed side contact portion 11 can contact two points on two different sides of the bullion In.
