Description

  The present invention relates to a method for producing a brush for cereals provided on an outer peripheral portion of a rotating body that is rotatably arranged in a dehuller tube.

  Such a brush for cereals is used, for example, in a rice polishing apparatus that removes rice cake remaining on the surface of polished rice after polishing, and is arranged to be freely driven to rotate in the removal cylinder. It is provided on the outer periphery of the rotating body so as to scrape off the rice cake from the surface of the rice grains transferred through the removal cylinder.

  Conventionally, as a method for producing such a brush for cereals, a method of planting hair groups in each of a plurality of bottomed recesses formed on the surface of a brush base that can be attached to a rotating body is employed. (For example, refer to Patent Document 1).

  When a conventional method for producing a cereal brush is described, although it is not clearly described in Patent Document 1, two bottomed recesses formed on the surface of the brush base are each The hair group was planted by performing a hair transplanting process in which a retaining member positioned in the valley of the folded hair group was fitted.

JP 2000-354773 A

  However, in the brush for cereals manufactured by the conventional manufacturing method, each of the plurality of hair bodies constituting the hair body group that is planted in a folded shape in each concave portion has a folded body Locking by a retaining member fitted in the recess in a state located in the valley of the group, and friction between the adjacent hairs and friction between the inner peripheral surface of the recess and the retaining member The entire ciliary body group planted in a folded manner in each concave portion is locked by the retaining member and the inner surface of the concave portion. Since the holding force to hold the hair bodies and the hair bodies constituting the hair bodies group so as not to come off is weak, It has been desired to make it difficult for the ciliary body group and the ciliary body constituting the ciliary body group to escape.

  That is, when a strong force is applied to a part of a plurality of hair bodies constituting the hair body group (for example, one or several hairs) in the grain of the grain, a part of the hairs. There is a risk that the hair-like body may come off, and if some of the hair-like bodies fall out, the holding power for holding the whole hair-like body group becomes weak and the whole hair-like body group may fall out. It is.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a method for producing a brush for cereals that can be planted so that it is difficult to escape the ciliary group while avoiding a decrease in the strength of the brush base. There is to do.

The method for producing a cereal brush according to the present invention is a method for producing a cereal brush provided on an outer peripheral portion of a rotating body that is rotatably arranged in a dehuller cylinder,
The first characteristic configuration is that each of a plurality of flocking holes formed in a state penetrating in the front and back direction of the brush base that can be attached to the rotating body is positioned in a valley portion of a fold-like ciliary body group. The hair retaining member is fitted so that the folded end of the bi-folded hair group protrudes to the back side of the brush base, and then the brush base is not melted. In the state, the plurality of hair bodies that protrude from the back side of the brush base are heated and melted to integrate the plurality of hair bodies constituting each hair body group, and the plurality of hair shapes It is characterized in that an integration process for integrating the protruding portion of the body group on the back side of the brush base is performed.

  That is, a retaining member positioned at the valley of the fold-like ciliary body group is formed in each of the plurality of flocking holes formed in a state of penetrating the brush base that can be attached to the rotating body in the front and back direction. , Performing a flocking process to fit the folded end of the bi-folded hair group so as to protrude to the back side of the brush base, and then a plurality of hair bodies without melting the brush base. The part protruding to the back side of the brush base in the group is heated and melted to integrate the plurality of hairs constituting each hair group, and the part protruding to the back side of the brush base in the plurality of hair groups By carrying out the integration process for integrating the hairs, the hair groups are implanted in each of the plurality of flocking holes.

  That is, in the integration process, the protruding portions of the plurality of hair groups to the back side of the brush base are integrally coupled to the plurality of hair bodies of each hair group, and the brush base is not melted. Each hair group is heated and melted in such a state that adjacent bodies are joined together, and solidified by cooling in this state, thereby avoiding a reduction in the strength of the brush base due to melting, and each hair. A plurality of hairs constituting the group of hairs are joined together, and an integrated body is formed that joins together the protruding portions of the plurality of hairs group to the back side of the brush base.

And each of the plurality of hair bodies constituting the hair body group planted in each hair transplantation hole is locked by the retaining member fitted in the hair transplantation hole, and the adjacent hair body and In addition to being prevented from slipping by friction between the inner surface of the hole for flocking and the inner peripheral surface of the flocking hole and by friction with the outer peripheral surface of the retaining member, it is prevented from coming off by being joined by an integrated object. As a result, it is possible to increase the holding force for holding the hairs so as not to slip out, so that the hairs cannot be easily pulled out.
In addition to the fact that the entire group of hairs planted in each flocking hole is locked by a retaining member and is retained by friction with the inner peripheral surface of the flocking hole, It becomes possible to strengthen the holding force for holding the whole of the ciliary body group by being bonded by the chemical compound, and a plurality of ciliary bodies constituting the ciliary body group It becomes possible to prevent each of the hair groups from falling out, and it is possible to suppress a decrease in holding power for holding the whole hair bodies group, so that it is difficult to remove the whole hair bodies group. .

By the way, without performing the integration process, in a state where the protruding portion to the back side of the brush base in the plurality of hair bodies is not heated and melted, in the thermoplastic resin having adhesiveness, in the plurality of hair bodies A manufacturing method is conceivable in which a covering process is performed to cover the protruding portion of the brush base on the back side.
However, in this manufacturing method, it is not possible to sufficiently strengthen the binding force for joining the plurality of hair bodies constituting the hair body group, and the holding force for holding the hair bodies so as not to come out is sufficient. Can not be strong.
On the other hand, the said integration process is performed, the protrusion part to the back side of the brush base in several hair body groups is heat-melted, and the several hair bodies which comprise a hair body group are integrated. Thus, the binding force for binding the hairs can be sufficiently strengthened, and the holding force for holding the hairs so as not to come out can be sufficiently strengthened.

  Therefore, it has become possible to provide a method for producing a brush for cereals in which hair can be planted in such a way that it is difficult to escape from the ciliary group while avoiding a decrease in strength of the brush base.

In addition to the first feature configuration, the second feature configuration is
It is characterized in that after the integration process, a coating process is performed to cover an integrated product formed on the back side of the brush base by the integration process with an adhesive thermoplastic resin.

That is, a coating process is performed after the integration process, and the integrated product formed on the back side of the brush base by the integration process is covered with a thermoplastic resin having adhesiveness.
In other words, in the coating process, it is possible to cover the integrated product with the thermoplastic resin while filling the gap between the integrated thermoplastic resin with the thermoplastic resin. It becomes possible to reinforce the strength of the integrated product and to further increase the binding force for joining together a plurality of hair bodies constituting each hair body group.

  Accordingly, it is possible to make it more difficult for the hair group grouped in each flocking hole to come out, and each of the plurality of hair bodies constituting the hair group grouped in each flocking hole. Therefore, it is possible to provide a method for producing a cereal brush that can be planted so as to make it more difficult to remove the ciliary group while avoiding a decrease in the strength of the brush base.

FIG.

  A retaining member 45 positioned in a valley portion of the fold-like ciliary body group 42 is provided in each of a large number of flocking holes 44d formed so as to penetrate the brush base 44 in the front and back direction. A flocking process is performed in which the bent end of the trifold-like hair group 42 is fitted so that it protrudes to the back side of the brush base 44, and then a plurality of hairs are formed without melting the brush base 44. The protruding part to the back side of the brush base 44 in the body group 42 is heated and melted to integrate the plurality of hair bodies constituting each hair body group 42, and the brush base 44 in the plurality of hair body groups 42. An integration process is performed to integrate the projecting portion to the back side of the brush, and after the integration process, an integrated thermoplastic resin 46 having adhesiveness is formed on the back side of the brush base 44 by the integration process. Coating covering the chemical compound 42a Perform the management, the production of grain milling brush B.

The hair bodies constituting the hair body group 42 are made of, for example, a material in which 6-12 nylon carries silicon carbide abrasive grains having a size of about 800 mesh and has a thickness of 0.4 mm or less. , About 0.25 mm.

By inserting, the retaining member 45 positioned at the valley of the bi-folded hair group 42 is in a state in which the bent end of the bi-fold hair group 42 projects to the back side of the brush base 44. Fit to be.
Then, the hair group 42 is planted in a cylindrical shape in each of the flocking holes 44 d of the brush base 44.

  Further, as shown in FIG. 4, the tips of all the ciliary body groups 42 are the same center as the center of the cylindrical outer peripheral surface of the polishing rice roll 41 in the axial direction view, and the protrusions 44a and 44c. The hair is implanted so as to be substantially positioned on a virtual curved surface having a radius of curvature R4 larger than the radius of curvature R1 of the surface.

As shown in FIG. 11, in the integration process, protruding portions to the back side of the brush bases 44 in the plurality of ciliary body groups 42 in a state where the brush bases 44 are not melted by an electric iron (not shown). In this state, the plurality of hair bodies of each hair group 42 are joined together and are melted in such a state that the joint bodies of each hair group 42 are joined together. By solidifying by cooling, a plurality of hair bodies constituting each hair body group 42 are combined together while avoiding a decrease in strength of the brush base 44 due to melting, and the plurality of hair bodies 42 are each combined. The integrated part 42a which joins together the protrusion part to the back side of the brush base 44 is formed.
Incidentally, when the brush base 44 is formed of a polyamide resin, the melting temperature of the brush base 44 is about 85 ° C., whereas the melting temperature of the hair group 42 made of 6-12 nylon is 185 ° C. Degree.

In the coating process, the target base cooling is performed so that the brush base 44 is held in a posture in which the concave portion 44 h faces upward, and the thermoplastic resin 46 heated and melted is prevented from penetrating into the ciliary body group 42 by capillary action. In the state cooled to the temperature, as shown in FIG. 12, the integrated product 42a is covered with a thermoplastic resin 46.
Specifically, in the state where the brush base 44 is cooled to the target cooling temperature, the thermoplastic resin 46 heated and melted is poured into each recess 44 h, thereby covering the integrated product 42 a with the thermoplastic resin 46. The integrated product 42a is covered with the thermoplastic resin 46 in a state where it is not higher than the two wall portions 44i.
Incidentally, the target cooling temperature is set to about −15 ° C., for example.

  That is, in the state where the brush base 44 is cooled, the molten thermoplastic resin 46 is poured into the upper part of the integrated product 42a of the plurality of hair bodies 42, thereby increasing the viscosity of the thermoplastic resin 46 and the molten heat. The plastic resin 46 is prevented from penetrating into the ciliary body group 42 by capillary action.

  Therefore, in the coating process, the gap between the integrated products 42a is filled with the thermoplastic resin 46 while preventing the plurality of hairs constituting the hair group 42 from being hardened by the penetration of the molten thermoplastic resin 46. At the same time, the entire surface or almost the entire surface of the integrated product 42 a can be covered with the thermoplastic resin 46.

  As the thermoplastic resin 46 having adhesiveness, for example, a hot melt type adhesive having a product number 2025 manufactured by Hirodine Co., Ltd. (ethylene vinyl acetate resin (EVA) as a main component) can be used.

Furthermore, in this embodiment, between the integration process and the covering process, the brush base 44 is heated to a set temperature for annealing, and an annealing process for correcting the warp of the brush base 44 is performed.
That is, if the integrated product 42a is formed by the integration process, stress may be generated and the brush base 44 may be warped. Therefore, the warping of the brush base 44 is corrected by performing the annealing process. Incidentally, the set temperature for annealing is set to 80 ° C., for example.

  By manufacturing the brush B for cereal by the manufacturing method as described above, a plurality of hairs constituting each hair body group 42 are combined together and integrated into a plurality of hairs by an integration process. In the body group 42, an integrated product 42a is formed to join together the protruding portions of the brush base 44 to the back side, and further, a thermoplastic resin 46 having adhesiveness is filled into the integrated product 42a by a coating process. The integrated product 42 a is covered with the thermoplastic resin 46.

Therefore, each of the plurality of hairs constituting the hair group 42 planted in each hair transplanting hole 44d is locked by the retaining member 45 fitted in the hair transplanting hole 44d and adjacent to each other. In addition to being prevented from slipping by friction with the hair, friction with the inner peripheral surface of the flocking hole 44d, and friction with the outer peripheral surface of the retaining member 45, it is coupled by the integrated member 42a. Since it is also prevented from coming off, the holding force for holding each hair is strengthened, making it difficult for the hair to come off.
In addition, the entire ciliary body group 42 implanted in each flocking hole 44d is locked by the retaining member 45 fitted in the flocking hole 44d, and the inner peripheral surface of the flocking hole 44d. In addition to being prevented from slipping off by friction between the two, since it is prevented from slipping by being joined by the integrated object 42a, the holding force for holding the hair group 42 becomes strong, and each hair group Each of the plurality of hairs constituting the hair 42 is difficult to come out, and a decrease in the holding force for holding the whole hair body group 42 can be suppressed, so that the hair body group 42 is hard to come off. .

  Furthermore, the integrated product 42a is coated with the adhesive thermoplastic resin 46, whereby the strength of the integrated product 42a is reinforced, and a plurality of hair bodies constituting each hair body group 42 are grouped together. Since the coupling force becomes stronger, the plurality of hair bodies constituting the hair body group 42 planted in each flocking hole 44d is more difficult to come out, and the hair shape planted in each flocking hole 44d. The entire body group 42 is also more difficult to escape.

  Then, when the grain brush B configured as described above is attached to the polishing roll 41 with bolts 43, the shape of the brush base 44 is the polishing roll 41 in the axial direction view as shown in FIG. The tip of the ciliary body group is substantially positioned on a virtual circumference having a radius R4 that is the same center as the center of the cylindrical outer peripheral surface of the polishing rice roll 41. Thus, even if the brush base 44 is mounted in the circumferential direction reversed, it can be polished under the same conditions.

By the air discharged to the outside and flowing in such a manner, the rice cake separated from the rice grains with the rice polishing in the rice polishing room 40, the residue from which the hair bodies of the hair group 42 were worn and separated, etc. Is discharged.
In addition, although the hair body of the hair body group 42 is worn out and a residue is generated, the amount thereof is, for example, that when a 20 t rice grain is polished, the hair body is only worn about 1 mm. As can be seen, the amount is extremely small, and the residue is discharged together with the soot by ventilation by the suction fan 29.

  Further, air is sucked in from the outside through the vent hole 22 by the suction action of the suction fan 29, and flows along the inner surface of the cylindrical portion 4a of the base frame 4, so that the transparent portion of the cylindrical portion 4a is in the same state. Is configured to prevent fogging.
