Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a grater used for grating radish, wasabi, etc.

In the conventional grater manufacturing process, the nail attachment process involves using a comb-like cutter and applying force diagonally to the grater surface with the tip of the teeth of the comb. By carving and repeating the process, many rows of nails were carved. However, with the grater manufactured in this way, the claws are too aligned vertically, so when grating the radish, they always hit the same spot, creating many grooves and ridges in the radish, causing the radish to crumble little by little. It is a daily experience that unless you hold the knife in a different position, you will not be able to cut it easily if you lower it in the same direction. The object of the present invention is to simply and quickly produce an efficient grater that does not have the drawbacks of conventional products, that is, can continue to grate radish in a good manner without having to change the radish every time. It is.

Next, the structure of the present invention will be described. The present invention is a method for manufacturing a grater in which a large number of claws 1 are carved vertically and horizontally on the surface of the grater. While changing the relative positional relationship of the grater by repeatedly advancing and stopping in the lateral direction of the grater, the nails that are lined up in the same line are individually carved by the nail attachment tool 2, and the adjacent ones are separated by controlling the advancement or stopping time. The method is characterized in that it includes a step of randomly changing the distance between each claw within a certain range.

Next, examples of the present invention will be described.

As a premise of the embodiments of the present invention, a machine is prepared in which a nail attaching tool operates at predetermined time intervals to bite diagonally into the surface of a grater fixed to a table and attach nails. .

A rack 5 is attached to the lower surface of the table 4, and the table can be moved in the axial direction of the rack 4 by connecting this rack to a worm gear 6 connected to a prime mover 7. This direction of movement coincides with the lateral direction of the grater 3 fixed to the table 4. In addition, this machine has a device (not shown) that can also move the table 4 in a direction perpendicular to the axis of the rack 5. Several rows of nails can be engraved with this device. The prime mover T for rotating the worm gear 6 is a servo motor, and is repeatedly activated and stopped by pulses controlled by the computer 8. This command pulse is changed by a random number. Further, the two are connected so that when the servo motor is stopped, the claw attachment tool 2 is operated and the claws are engraved on the grater. To explain the method of manufacturing a grater using such a system, a semi-finished grater with no claws attached is fixed on the table 4, and a switch is turned on to send pulses to the servo motor.

The servo motor is operated intermittently by the pulses, and the operating time is changed randomly by inputting random numbers, so the distance traveled by the table, which is repeatedly advanced and stopped by the servo motor, changes little by little. Therefore, the respective spacing of the grater claws 1 applied by the claw applicator 2 while the table is stopped also changes. To obtain a desirable product,
Random numbers may be taken so that the spacing can be varied within a range of ±0.25 with respect to a predetermined standard claw spacing. This process creates one row of nails, and once one row is completed, the table is moved lengthwise along the grater to add another row of nails. In this way, a number of rows of claws are engraved on the grater. When grating daikon radish using a grater,
If you can't grate the radish in either direction when moving it back and forth in the vertical direction of the grater, it won't be efficient, so the claws must be oriented in opposite directions for each row. That is, the claws are oriented in the same direction in every other row, as shown in FIG. For this purpose, in this embodiment, as shown in FIG. 3, two nail applicators tilted in opposite directions operate simultaneously to carve two rows of nails at once. 1 nail attachment
When using only one piece, just change the direction of the grater and repeat the same process. The present invention has the above configuration,
Since the claws are attached by randomly changing the spacing between adjacent claws in the horizontal direction, the grater produced by this method has uneven rows of claws in the vertical direction.

That is, as shown in FIG. 2, the claws overlap when viewed from the vertical direction. For this reason, when the radish is being grated, the entire surface of the radish is always scraped by one of the nails. Therefore, (unlike conventional products, the grater does not become uncut immediately after use). Since the present invention mechanically produces such an excellent grater, it can be produced in a short time and at low cost. Since the claws are attached mechanically individually using attachment tool 2, even on hard metals such as stainless steel, larger claws can be attached reliably.The larger claws allow you to grate the radish quickly. Although it is sometimes necessary, it has been impossible with conventional methods to apply large claws evenly to hard metals such as stainless steel.Furthermore, graters with claws attached to hard metals have the advantage of a long sharpness life. The present invention has the effect that such an excellent grater can be easily manufactured.
Several patterns of how to apply the nails were recorded on magnetic tape, and graters with each pattern were manufactured.
If, through trial and error, a pattern is selected that allows the most efficient radish preparation to be made into a product, it will be well-received in the market.
