[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a gold bullion stamping device.
In particular, it relates to a device that automatically stamps melter's marks, purity, weight, and serial numbers on small gold bullion bars of 100 g and 200 g.

0002

[Prior Art] Conventionally, 100g, 20g as shown in FIG.
To stamp melter's mark 2, purity 3, weight 4, and serial number 5 on a small gold bullion bar 1 weighing 0 g, press the stamp body that stamps melter's mark 2, purity 3, and weight 4 together. The size and the numbering for stamping the serial number 5 were larger than the gold bullion bar 1 and could not be stamped at the same time, so each was stamped separately.

0003

However, in the above-mentioned stamping method, stamping requires two steps, which doubles the time, resulting in poor productivity. In addition, since the gold bar 1 is moved manually,
It may get scratches, oil, etc. and reduce the product value.

[0004] Therefore, the present invention has a method of automatically moving small gold bullion bars and simultaneously stamping the melter's mark, purity, and weight on one of the two gold bullion bars, and the serial number on the other. It is an object of the present invention to provide a gold bullion stamping device that successively improves the productivity of gold bullion bars and prevents the commercial value from decreasing.

[0005]

[Means for Solving the Problems] In order to solve the above problems, the gold bullion stamping device of the present invention has a stamping body that stamps a serial number, a melter's mark, purity, and a weight together. A vertically movable stamping machine holds the bar downward on both the left and right sides, and a gold bullion bar is placed on the receiving position of this stamping machine in the right angle direction in front of the stamping position below the numbering, and the bar is transferred to the stamping position below the numbering. A receiving air cylinder has a receiving stand at its tip, and a receiving stand at its tip, which transfers the gold bullion bar stamped at the stamping position below the stamping body of the stamping machine to the take-out position at right angles to the rear of the stamping position. and a press tool on the side for transferring the gold bullion bar stamped at the stamping position below the numbering to the stamping position below the stamping body, parallel to the stamping machine. A positioning jig is provided for positioning the gold bars on both the left and right sides of the air cylinder and the base for passing the gold bars between the lower stamping position of the numbering and the lower stamping position of the stamp body. It consists of an air cylinder installed at the tip.

[0006]

[Operation] To explain the operation of the gold bullion stamping device of the present invention configured as described above, 100g of gold bullion that has passed the weighing
Alternatively, when a small gold bar weighing 200g is placed on the receiving table that has been placed in the receiving position, the receiving air cylinder is activated and the receiving table with the gold bar placed on it is placed under the numbering of the stamping machine. It is transported to the stamping position. At the start of work, there is no gold bar at the stamping position below the stamping body of the stamping machine, so the gold bar transferred to the stamping position below the numbering continues to be passed by a pressing tool by the operation of the transfer air cylinder. The stamp is transferred through the marking stand and placed on a receiving stand positioned at the stamping position below the marking body. Then, the receiving air cylinder is operated and the receiving stand at its tip returns to the receiving position, waiting for the next gold bar. When the next gold bar is placed on the receiving table, the receiving air cylinder is activated and the bar is transferred to the stamping position below the numbering. When the two gold bars are positioned in the stamping machine in this way, the positioning jig moves forward between the two gold bars by the operation of the air cylinder, and the positioning jig moves the two gold bars into the stamping machine. The bar is positioned and fixed on the receiving table. Then, the stamping machine descends and a serial number is stamped on one of the gold bullion bars by numbering, and the melter's mark, purity, and weight are stamped on the other gold bullion bar by the stamping body. After stamping, the stamping machine rises, the positioning jig is moved back by the operation of the air cylinder, and the gold bar below the stamping body is sent to the takeout position while remaining on the receiving table by the action of the takeout air cylinder. Since this gold bullion bar is just the beginning of work, there is no serial number stamped on it, so it is placed in a dummy box after being taken out. When the receiving base at the tip of the take-out air cylinder returns to the stamping position below the stamp body, the gold bar with the serial number stamped on it is pressed by the pressing tool by the operation of the transfer air cylinder. It will be sent and posted. When the pressing tool returns to its original position, the receiving table located at the stamping position below the numbering is moved to the receiving position by the operation of the receiving air cylinder, and waits for the next gold bar to be delivered. Thereafter, the above process is repeated, and the serial number, melter's mark, purity, and weight are automatically stamped on the gold bullion bar in sequence.
They are taken out at the take-out position and arranged on a pallet.

[0007]

[Embodiment] An embodiment of the gold bullion stamping apparatus of the present invention will be explained with reference to the drawings. In FIG. 1, 10 is a stamping machine that can move up and down, and the serial number is stamped on both the left and right sides of the holder 11 as shown in FIG. A numbering 12 to be engraved and a marking body 13 to be engraved with a melter's mark, purity, and weight are held facing downward. The stamping machine 10 has a receiving stand 14 on which the gold bar 1 is placed at the stamping position B below the numbering 12, and this receiving stand 14 is located in front of the stamping position B in the right angle direction as shown in FIGS. 2 and 4. In order to place a gold bullion bar at the receiving position A and transfer it to the stamping position B, the base is attached to the tip of a receiving air cylinder 16 arranged and fixed on the base 15 at the rear of the stamping position B in the right angle direction. It is adapted to slide on the table 15. The stamping machine 10 shown in FIG.
As shown in FIGS. 2 and 4, in order to transfer the gold bar 1 stamped by the stamping body 13 at the stamping position C to the take-out position D at right angles to the rear of the stamping position C, A take-out air cylinder 18 is arranged and fixed on the base 15 at the front in the right angle direction.
It is attached to the tip of the base 15 and slides on the base 15. On the outside of the stamping position B, there is a pressing tool 19 for transferring the gold bar 1 stamped with the numbering 12 to the stamping position C by an air cylinder, and this pressing tool 19 is arranged parallel to the stamping machine 10. Transfer air cylinder 20 provided

4 is opened laterally and widened, and the two gold bars 1 are respectively latched to stoppers 27 on the receiving stands 14 and 17 by rollers 25 at both ends of the link 24, and are positioned and fixed. Then, the stamping machine 10 descends, and the serial number 5 shown in FIG. 5 is stamped on one of the gold bars 1 by numbering 12.
On the other gold bar 1, a melter's mark 2, purity 3, and weight 4 shown in FIG. 5 are stamped by the stamp body 13. After stamping, the stamping machine 10 rises, the positioning jig 22 shown in FIGS.
8, it is sent to the take-out position D while remaining on the receiving table 17. Since this gold bullion bar 1 has not been stamped with a serial number since it is the beginning of work, it is placed in a dummy box (not shown) after being taken out. When the receiving stand 17 at the tip of the take-out air cylinder 18 returns to the stamping position C, the gold bar 1 on which the serial number is stamped in the numbering 12 is pressed into the press tool 19 by the operation of the transfer air cylinder 20. It was sent to me and posted. When the pressing tool 19 returns to its original position, the receiving stand 14 located at the stamping position B is moved to the receiving position A by the operation of the receiving air cylinder 16.
, and wait for the next gold bar 1 to be delivered. Thereafter, the above-mentioned process is repeated, and the serial number, metal mark, purity, and weight are sequentially and automatically stamped on the gold bars 1, and the gold bars 1 are taken out at the take-out position D and arranged on a pallet (not shown).

[0009]

As described above, according to the gold bullion stamping device of the present invention, a small gold bullion bar of 100 g or 200 g can be automatically moved and a melter's mark can be placed on one of the two gold bullion bars. Since it is possible to simultaneously stamp the purity and weight and the serial number on the other side, the stamping efficiency is improved and the productivity of the gold bullion bar is improved. Furthermore, since stamping is performed completely automatically without manual intervention, the gold bar will not get scratched or oily, and the product value will not decrease.
