Description

  The present invention relates to a granular material supply apparatus that supplies granular materials one by one.

  One type of grain is an abrasive used for a grindstone. When this abrasive grain is electrodeposited on a base metal, an electrodeposition grindstone can be produced. However, when electrodepositing a plurality of abrasive grains on the base metal, if the abrasive grains are concentrated on a specific part of the electrodeposited surface of the base metal, a grindstone in which the abrasive grains are electrodeposited on the specific part of the base metal is manufactured. Therefore, a technique for preventing the deviation of the abrasive grains is required.

  Conventionally, a method for manufacturing an electrodeposition grindstone in consideration of dispersibility of abrasive grains with respect to a base metal is known (for example, see Patent Document 1 (see FIG. 1A)).

Patent document 1 is demonstrated based on the following figure.
FIG. 11 is a diagram for explaining the basic principle of the prior art. As shown in FIG. 11A, the masking sheet 300 covers the ink 302 made of thermosetting resin solidified on the transfer paper 301 with a film 303. It is a sheet. The ink 302 is provided on the transfer paper 301 except for a plurality of non-masking portions 304 that are open at a constant pitch.

  The masking sheet 300 is soaked in chemicals, and the ink 302 is peeled off for each film 303 and is attached to the electrodeposited surface 306 of the base metal 305 as shown in FIG. Next, only the film 303 is peeled off, and the base metal 305 is immersed in the electrodeposition liquid 307 in the electrodeposition tank, as shown in (c). Since a plurality of non-masking portions 304 are formed on the base metal 305, abrasive grains can be arranged on the non-masking portions 304. Since the plurality of non-masking portions 304 are provided on the entire electrodeposited surface 306 of the base metal 305, the abrasive grains can be dispersed and arranged.

  By the way, when arrange | positioning an abrasive grain in the non-masking part 304 of patent document 1, since an abrasive grain is made to adsorb | suck with an air tweezers and it puts into the electrodeposition liquid 307, the electrodeposition liquid 307 may be suck | inhaled with an air tweezers. When the air tweezers sucks the electrodeposition liquid 307, the air tweezers are broken.

  Therefore, an abrasive supply device that can be used in a liquid is required.

  In FIG. 10, the same reference numerals are used for the same structures as those in FIG. The first fan-shaped cross-section column 20B does not include a fall prevention member (reference numeral 161 in FIG. 3). Further, the second fan-shaped cross-section column 30B also does not include the fall prevention member (reference numeral 162 in FIG. 3).

  Since there is no fall prevention member, when there are no abrasive grains, the spring mechanism (reference numeral 210 in FIG. 9) is removed with the abrasive supply cartridge 40B attached to the abrasive supply apparatus (reference numeral 10B in FIG. 9). Next, the abrasive grains are supplied to the abrasive supply cartridge 40B. That is, it is possible to smoothly supply the abrasive grains.

In addition, although the abrasive grain was applied to the granule based on this invention in embodiment, since activated carbon etc. can be applied besides this, it does not interfere to apply a general granule.
