[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a punch and rod supporting device in a rice-milling machine for automatically stopping the operation of a freely falling punch and rod at a high position.

[0002]

[Prior art]

 In the past, when mochi was milled with a free-falling punch, it had to be stopped when the punch rod was in the raised position, but since it was a manual stop, the timing could be shifted, so it was skillful to stop at a good position Cost.

[0005] Further, there has been proposed a device in which the position of the punch rod is detected by a sensor, the intermediate portion of the punch rod is supported, and stopped at the raised position (Utility Model Registration No. 2603042).

[0004]

[Problem to be solved by the invention]

 The conventional manual support device is slightly difficult for an unskilled operator, and the stop position of the punch rod may be unstable.

A known utility model is to detect the movement of a cam with a sensor and to lock a stopper body in a concave groove of a punch rod, which has given a certain effect. It is intended to be further improved.

[0006]

[Means for Solving the Problems]

 This invention and the above-mentioned known example are considered to have substantially the same purpose in that the ascent position of the punch rod is detected and stopped at the ascended position.

However, in the present invention, the necessary cam plate is always used at the upper end of the punch rod as a retaining plate, and the sensor is devised to complete the present invention.

[0008] That is, the present invention relates to a rice cake milling machine in which a punch rod with a punch is installed above and below a die so as to be able to move up and down, and the rice cake is polished by the free fall of the punch. Means for supporting the punching rod in the rice cake milling machine, wherein the punching rod is provided with a punching rod above and below the mill so that the punching rod can be raised and lowered. In a rice-milling machine designed to mill rice cakes by free fall, a cam receiving plate is fixed to the upper end of the punching rod, and a sensor for detecting the tip of the cam at the highest position of the cam receiving plate is installed. A punching rod support device for a rice-milling machine, characterized in that a punching rod supporting means operated by an output of the detecting means is provided.

[0009] Further, another invention is a rice cake milling machine in which a punch rod with a punch is installed so as to be able to move up and down over a die, and the rice cake is polished by the free fall of the punch. In addition to the provision of the detecting means, the supporting rod which is engaged with the cam receiving plate fixed to the upper end of the punching rod is provided at the raised position of the punching rod, and the supporting rod is operated by the output of the detecting means. In a mochi milling machine, the mochi milling machine is characterized in that a moisturizing machine is provided in which a moisturizing device is provided, in which a moisturizing device is installed above a mill so that a moisturizing bar can be milled by free fall of the moat. A cam receiving plate is fixed to the upper end of the punch rod, and a sensor for detecting the tip of the cam at the highest position of the cam receiving plate is installed to constitute a detecting means, and a support for engaging with the cam receiving plate is provided. A supporting means for driving the rod by the output of the detecting means, and A punch and rod supporting device in a rice-milling machine, characterized in that the device is connected to a detecting means.

[0010] Further, in a rice cake milling machine in which a punch rod with a punch is set up and down freely above the mortar, and the rice cake is polished by free fall of the punch, a cam for detecting the rising position of the punch rod is provided. When the protrusion fixed to the shaft and the cam fixed to the cam shaft raises the punch rod to the highest position, a sensor for detecting the protrusion is installed to constitute detection means, and the output of the detection means is provided. A punch and rod supporting device in a rice cake mill characterized by further operating a punch and rod supporting means.

[0011] In the above, the detecting means detects the cam receiving plate with a sensor.

[0012] The sliding of the locking rod in the above-mentioned invention is supposed to be performed by an air cylinder, but it is needless to say that an oil cylinder may be used. Therefore, when the punching rod reaches the highest position, the locking rod protrudes, and locks and supports the locking plate (cam receiving plate). In this case, if the latching rod is pushed out before the punching rod reaches the highest position (when the timing is out of order), the latching rod may collide with the latching plate and be damaged. I do.

[0013]

[Embodiment of the invention]

 In this invention, a mochi milling machine that naturally falls a punch and grinds a mochi is configured to support the punch at an ascending position when the mochi is stopped. Therefore, the mochi milling machine is instructed to stop, or the mochi time is made constant by a timer or the like to stop the punch.

In the present invention, when the punch rod reaches the uppermost position, the locking rod is slid by an air cylinder or other power by the output of a sensor when the punch rod reaches the uppermost position, and is fixed to the upper end of the punch rod. And the punch rod is supported at the raised position. The support at the ascending position is because it is obstructive if the punch rod is supported at the lower position.

In the present invention, the detection of the punch rod is performed by detecting a cam, a projecting piece of a cam shaft, and the like by a sensor, and locking the locking rod and the cam receiving plate or the punch rod so that the punch rod has a predetermined height. To support.

Embodiment 1 An embodiment of the present invention will be described with reference to FIGS. A lower base plate 2 is provided at the lower part of one side of the column 1, an upper frame 3 is provided above the column 1, and a frame 4 is set on the upper frame 3 (FIG. 1).

An abutment 5 is placed on the lower base plate 2, and a receiving stand 7 of a die 6 is placed on the abutment 5. A punch rod 9 of a punch 8 is attached to the upper frame 3 and the frame 4 so as to be able to move up and down, and a cam receiving plate 10 is fixed to the upper end of the punch rod 9. A cam shaft 11 is mounted on the upper frame 3, and the base of the cam 12 and the projecting piece 11 a are fixed to the cam shaft 11, and the cam receiving plate 10 is brought into contact with a cam edge 12 a of the cam 12 to 9 is raised. In the drawing, 13 and 14 are motors, 15 and 16 are pulleys fixed to the motor shaft, and 17 and 18 are shafts 19 of the rotary plate 6 a at the center of the die 6 and pulleys fixed to the cam shaft 11. The air cylinder 20 is placed laterally on one side of the frame 4, and the rod 21 of the air cylinder 20 (which may be a hooking rod or a hooking piece may be connected) raises the punch rod 9 to the top. In this case, the cam receiving plate 10 is slidably engaged with the flange 10a. Further, the sensor 22 is mounted on the upper underframe 3, and the highest position of the punch rod 9 is detected by the detection piece 22 a of the sensor 22 and the protrusion 11 a of the cam shaft 11.

In the above embodiment, when the motor 13 is started, the shaft 19 of the rotary plate 6 a of the mill 6 is rotated via the pulley 15, the belt 23, and the pulley 17. When the motor 14 is started, the camshaft 11 is rotated via the pulley 16, the belt 24, and the pulley 18. The cam 12 is rotated by the rotation of the camshaft 11, and the cam receiving plate 10 is brought into contact with the cam edge 12 a of the cam 12. When the cam 12 is disengaged from the cam receiving plate 10 as shown by arrow 25, the punch rod 9 is lowered by its own weight as shown by arrow 26, and the rice cake 27 in the die 6 is moved. (Fig. 1).

When the rice cake 27 has been polished as described above, the timer 28 in FIG. 5 closes the circuit 30 of the electromagnetic valve 29. Then, when the punch rod 9 is raised and the detecting piece 22a of the sensor 22 detects the protruding piece 11a of the camshaft 11, the circuit 30 is completed. When the electromagnetic valve 29 is opened, pressurized air is supplied through the air pipe 31 as indicated by an arrow 32 and is supplied to one side of the air cylinder 20 as indicated by an arrow 33. Therefore, the rod 21 protrudes as indicated by an arrow 34, engages with the cam receiving plate 10, and supports the punch rod 9.

Next, when the manual switch 35 is turned off and the sensor 22 detects the projecting piece 11a, the circuit 30 of the electromagnetic valve 29 is opened, the electromagnetic valve 29 is switched, and the pressurized air of the air cylinder 20 is indicated by an arrow. Since the rod 21 is released to the outside as indicated by 36 and 37, the rod 21 is retracted by the spring 38 as indicated by an arrow 39. Then, the hook between the rod 21 and the cam receiving plate 10 is released, the punch rod 9 falls freely, and the rice-milling is started.

In the above-described embodiment, the circuit 30 of the electromagnetic valve 29 is closed by the timer 28, but the same applies when the circuit is closed by the manual switch 40.

In the embodiment (FIG. 5), when the sensor 22 detects the protruding piece 11a, the pressurized air is supplied into the right side of the air cylinder 20, and the rod 21 protrudes as indicated by an arrow 34. The cam receiving plate 10 was supported. When the hook 9 is released, the pressurized air in the air cylinder 20 is discharged, and the rod 21 is retracted by the elasticity of the spring 38 so that the punch 9 can be lowered. In another embodiment (FIG. 6), when the sensor 22 detects the protrusion 11a, the pressurized air contained in the left side of the air cylinder 20 is discharged as shown by arrows 44 and 45. In this case, the rod 21 protrudes as indicated by an arrow 46 by the elasticity of the spring 38 and supports the punch rod 9. Next, when the sensor 22 detects the projecting piece 11a after issuing a command to release the support of the punch rod 9, the pressurized air is supplied to the air cylinder 20 as indicated by an arrow 47, so that the rod 21 is As shown by the arrow 48, the lever 9 is retracted to release the support of the punch 9.

Although the workings of the pressurized air and the spring are reversed in the embodiment of FIG. 5 and the embodiment of FIG. 6, the technical ideas of detection and support are the same.

[0024]

Second Embodiment Next, another embodiment will be described with reference to FIG. In the embodiment of FIG. 3, the air cylinder 20 is placed on one side of the frame 4 and the sensor 22 is installed on the other side, and the tip 22b of the cam 12 is detected by the detection piece 22a of the sensor 22. Things.

In this embodiment, the installation location of the sensor 22 is changed, and the detection target is changed from the projecting piece 11 a of the cam shaft 11 to the tip 12 b of the cam 12.

Although there is no great difference in the mechanism for supporting the punch and rod, there is an advantage that the number of parts is reduced in that a cam is used, and the detection is directly performed. In addition, the hooking rod 21 supports the cam receiving plate 10, but as shown in FIG. 8, the hooking rod 21 may be hooked on a collar 9 a fixed to the punching rod 9 to support the punching rod 9.

[0027]

Embodiment 3 In the embodiment of FIG. 7, a rod 42 is slid by a cam plate 41 fixed to a cam shaft 11, and an end of the rod 42 is detected by a detection piece 22 a of a sensor 22. .

In FIG. 7, when the cam 12 pushes the cam receiving plate 10 to the highest position, the projection 41 a of the cam plate 41 expands the rod 42 to the spring 43 and pushes out the rod 42 as shown by an arrow 49. The cam 12 and the cam plate 41 are synchronized.

Then, when a command is issued to support the punch rod 9, the rod 42 is pushed out by the cam plate 41 in the direction of the arrow 49 by the spring 43, whereby the sensor 22 detects and the rod 22 is supported. I do. The detection by the sensor in the above is completed once, and thereafter, even if the rod 42 projects, the sensor 22 does not detect it. Similarly, when releasing the support of the punch rod 9, the rod 42 is detected and the support of the punch rod is released.

This point is the same in each embodiment, because it is assumed that the cam shaft needs to be rotated as it is even when the lifting and lowering of the punch rod is stopped.

For example, when a plurality of cams are rotated by the same cam shaft to perform a plurality of rice-milling operations, there is naturally a simultaneous stop at the same time, but one is rice-milling and the other is stopped. This is because there are cases. The punch rod can be supported or released even when the camshaft is rotating.

[0032]

[Effect of the invention]

 According to this invention, there is an effect that the punch rod can be automatically stopped at the raised position when the rice cake milling is stopped. In addition, since the punch is supported at the top, the punch will fall freely from the top when the rice-milling starts.
