The planting hole 5 has an inclination angle of >0° and <20° in the circumferential direction of the roll brush, and an inclination angle of >0° and <20° in the axial direction, and the brush bundle 6 is planted in a direction along the inclination angle of the planting hole 5.

Description

  The present invention relates to a roll brush. More specifically, the brush bristles are inclined flocks, so that the distance between the bristles is narrowed, and the bristles are brought into contact with the cleaning body with certainty. The present invention relates to a roll brush that is excellent in quality and can stably transport a cleaning body.

Roll brushes are known as cleaning brushes for cleaning and polishing agricultural products (root vegetables, fruits, vegetables, etc.) and industrial products. A conventional general roll brush has a cylindrical brush substrate attached to a rotating shaft, and brush hairs are implanted on the brush substrate.
In addition, cleaning devices and other various devices using a roll brush have been proposed as follows.

  For example, a cleaning device for root vegetables disclosed in Patent Document 1 is a device that performs cleaning by spraying high-pressure water onto an object to be cleaned such as a flat-shaped long bean or a leaf radish, and in the longitudinal direction. An inner cleaning roll brush disposed alongside, an outer cleaning roll brush positioned on the outside, and a splash preventing brush for an object to be cleaned positioned above. Brushes planted on the inner cleaning roll brush or the outer cleaning roll brush are planted by tilting in the direction in which the object to be cleaned advances, thereby cleaning the object without damaging the object to be cleaned It is.

  The root vegetable washing machine disclosed in Patent Document 2 is a plant in which a linear body to be planted on a cleaning brush is planted in an inclined posture in a discharge direction in a concave portion and an ascending slope portion, thereby smoothly transporting root vegetables. At the same time, by planting the linear body without inclining in the convex part and the descending slope part of the cleaning brush, and arranging a plurality of cleaning brushes so that the concave part and the convex part are offset, This is an apparatus that efficiently performs both cleaning operations.

  The supply device of the fruit sorter disclosed in Patent Document 3 is a stepped, U-shaped, or V-shaped cross-sectional shape of a spiral groove that fits a selected item and conveys it in the axial direction on a rotating peripheral surface of a brush roll. Thus, the central part is formed deeply. As a result, when a plurality of sorts are supplied onto the sorter of the sorter, it is possible to accurately maintain the supply of one sort.

  The fruit and vegetables feeding roller disclosed in Patent Document 4 has a brush having a different planting inclination angle with respect to the axial direction, and is placed on the brush roll that carries the fruit and vegetables by rotation and conveys it in the axial direction. This roller is formed so as to intersect with the rotation direction in an oblique direction, and forms a delivery edge that engages the conveyed fruits and vegetables and feeds them to the end side. As a result, the fruits and vegetables being conveyed do not jump over or over the rotating peripheral surface of the spiral brush, and the fruits and vegetables can be fed and conveyed accurately one by one.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
(Roll brushes 1A-1C, 2A-2C, 3A, 3B, 4A, 4B)
Roll brushes 1A, 1B and 1C shown in FIGS. 1A to 1C, roll brushes 2A, 2B and 2C shown in FIGS. 2A to 2C, roll brushes 3A and 3B shown in FIGS. 3A and 3B, and FIGS. 4A and 4B. Roll brushes 4A and 4B (hereinafter collectively referred to simply as “roll brush 1A etc.”) are used for cleaning or sorting agricultural products or industrial products. A roll brush 1A or the like is a cylindrical or cylindrical stainless steel or other metal shaft formed in a shaft hole 3 formed in a ring-shaped roll brush substrate 2 (hereinafter simply referred to as “substrate 2”) in an axial sectional view. 4 is mounted, and a bristle bundle 6 is planted in a planting hole 5 formed in the substrate 2. Here, the “brush bristle bundle 6” is obtained by bundling dozens of brush bristles 6a with a round wire 7 made of stainless steel or other metal and folding it in half (that is, a bunch of brush bristles 6a. (See FIG. 5 (4)). The diameter of the substrate 2 is not particularly limited, but is preferably 50 mm or more and 150 mm or less, and more preferably 70 mm, 80 mm, 90 mm, or 100 mm.

As shown in FIG. 5, the roll brush 1 </ b> A and the like are (1) production of the substrate 2 → (2) mounting of the shaft 4 → (3) formation of the flocking hole 5 → (4) brush hair bundle 6 to the flocking hole 5. It is produced by the procedure of flocking. Among these, the formation of the flocked holes 5 of the roll brushes 1A to 1C and 2A to 2C and the flocking of the bristles 6 to the flocked holes 5 are performed by spiral flocking. Here, “spiral flocking” means that the flocking hole 5 inclined at an inclination angle α (described later) and an inclination angle θ (described later) is formed in the hole formation path shown in FIG. The method for flocking the brush hair bundle 6 to the hair also refers to a method performed through the flocking route shown in FIG. In addition, the formation of the flocked holes 5 of the roll brushes 3A, 3B, 4A, and 4B and the flocking of the bristles 6 in the flocked holes 5 are performed by 2D flocking. Here, “2D flocking” means that when the inclination angle θ (described later) is 0 ° (that is, there is no inclination in the axial direction),
(1) An inclined flock hole 5 (described later) inclined, or
(2) Flocking hole 5 having an inclination angle α of 0 °,
Is formed by the hole formation route shown in FIG. 3C (hereinafter the same).

(Roll brush 1A-1C: Spiral flocking of regular formula)
The roll brushes 1 </ b> A to 1 </ b> C are straight cut type, taper cut type, and wave cut type roll brushes, respectively, and are based on regular spiral flocking. Here, the “regular expression” means that the inclination angle α (described later) and the inclination angle θ (described later) are constant (unified).
The roll brushes 1A to 1C are those whose shape and size are determined according to the shape of agricultural products or industrial products to be cleaned or sorted, so that the overall shape of the roll brush is a desired shape.
(1) The shape of the substrate 2 is formed in each shape, or
(2) It is produced by forming a brush length (described later) in each shape (this embodiment is based on this).

  The flocking holes 5 of the roll brushes 1A to 1C all have an inclination angle α in the circumferential direction of the roll brush of more than 0 ° and less than 20 °, and an inclination angle in the axial direction of more than 0 ° and less than 20 °. (Regular formula spiral flocking).

  Here, “inclination angle α in the circumferential direction” (hereinafter simply referred to as “inclination angle α”) means that the substrate 2 is placed horizontally as shown in FIG. 1A (the same applies to other embodiments). When viewed from the axial direction, the “inclination direction A of the flock hole 5 for flocking the bristle bundle 6” is “radial direction B (for example, vertical direction) passing through the center of the shaft 4 such as the roll brush 1A”. "Is an angle deviating from the absolute value (indicated by an absolute value, especially when it is necessary to indicate a direction, the same applies hereinafter). The inclination angle α is preferably less than 20 °, more preferably 15 ° or less.

  Further, the “inclination angle θ in the axial direction” (hereinafter simply referred to as “inclination angle sθ”) means that the substrate 2 is placed horizontally as shown in FIG. 1A (the same applies to other embodiments). When viewed from the front direction (side direction), “the inclination direction C of the flock hole 5 for flocking the bristles 6 is“ the radial direction D (for example, the vertical direction) passing through the center of the shaft 4 such as the roll brush 1A ”. ) "(Refers to an absolute value, and in particular, if it is necessary to indicate the direction, the same is applied). The inclination angle θ is preferably less than 20 °, more preferably 15 ° or less.

  If the diameter of the flocked hole 5 is d, the depth is preferably 1.5d to 2.5d. Specifically, the flock hole 5 has a diameter of 0.5 to 20 mm, more preferably a diameter of 2 to 15 mm, a depth of 1 to 40 mm, and more preferably a depth of 4 to 30 mm, but is not limited thereto.

  The bristle bundle 6 has a flocking direction along the inclination angle α and the inclination angle θ of the flocking hole 5. The brush bristle bundle 6 is implanted in the flock hole 5 inclined at the inclination angle α and the inclination angle θ. The bristle bundle 6 is planted in such a manner that each bristle 6a grows from the bottom of the tuft hole 5. Therefore, the flocking direction of the bristle bundle 6 is flocked within the range of the inclination angle α ± schedule error (described later) in the circumferential direction and flocked within the range of the inclination angle θ ± schedule error in the axial direction. Is done. The “scheduled error” is based on the premise that the brush bristles 6a are planted in a state where the bristles 6a grow from the flock holes 5, so that the inclination angles of all the brush bristles 6a are approximately the inclination angle α and the inclination angle θ. means.

The flocking length of the bristle bundle 6 is obtained by adding the embedding length of the portion that is embedded in the roll brush substrate 2 and cannot be seen from the outside, and the brush length of the portion that appears outside from the roll brush substrate 2 and that is visible from the outside. (Flocked length = embedded length + brush length).
The brush length is specified according to the application and is not particularly limited, but is preferably 8 to 450 mm, more preferably 90 mm (the brush length is cut and aligned after flocking is performed). The length of the state where the single round wire 7 of the brush hair is not applied is not particularly limited and is specified according to the application in consideration of the brush length, the embedding length, and the cut amount, but about 50 to 150 mm is a preferable range. .
Of the materials described later, the brush bristles 6a are particularly preferably nylon (particularly 66 nylon is preferred), polypropylene, vinyl chloride, polyethylene terephthalate, polyphenylene sulfide, animal fibers, and plant fibers, and have a diameter of 0.1 to 1. 2 mm (especially practically made of 66 nylon and preferably 0.2 mm, 0.3 mm, 0.4 mm, and 0.5 mm) is preferable, and the number of turns shown in Table 1 described later is preferable (automatic flocking) Since the hair is planted by the machine, there are variations, but the values shown in Table 1 are expected to vary 20% up and down). As described above, the brush length is preferably 8 to 450 mm, and more preferably 90 mm. The material of the round wire 7 is preferably made of stainless steel, but is not limited thereto.

  FIG. 1E and FIG. 1F are drawing substitute photos of the roll brush 1A. The roll brush 1A shown in these drawings is made of two kinds of materials (indicated by the color coding of the brush bristle bundle 6). In this way, a plurality of types of brush hair bundles 6 may be combined. For example, a roll brush shown in Table 2 below is an example. What is necessary is just to select suitably how to combine according to a use.

(Roll brush 2A-2C: Spiral flocking of irregular formula)
Each of the roll brushes 2A to 2C is a straight cut type roll brush, which is based on an irregular spiral flocking. Here, “anomalous expression” means that the inclination angle θ is not constant (non-uniform or changes regularly). Further, in the flocking holes 5 of the roll brushes 2A to 2C, the inclination angle α in the circumferential direction of the roll brush is greater than 0 ° and less than 20 °.

  Among these, the flock holes 5 of the roll brush 2A have an inclination angle θ in the axial direction of 0 from an inclination angle θ that exceeds −20 ° from both end portions of the roll brush 2A toward the center of the roll brush 2A. Or an angle that gradually changes from an inclination angle θ of less than + 20 ° to 0 °. Further, in the flocking hole 5 of the roll brush 2A, the inclination angle θ of “a portion other than both axial end portions” is 0 °. Here, the “both end portions in the axial direction” includes a portion that gradually changes from both ends in a strict sense until just before the inclination angle θ reaches 0 °. In particular, in the roll brush 2A, the both ends of the brush bristle bundle 6 are open, so that the objects to be cleaned and the objects to be sorted are prevented from dropping onto the shaft 4.

  Next, the flocking holes 5 of the roll brush 2B regularly have an inclination angle θ in the axial direction of 0 ° and an inclination angle of more than 0 ° and less than 20 ° for each predetermined number of bristles. To do. In the roll brush 2B, four rows of brush hair bundles 6 with an inclination angle θ of 0 ° and two rows of brush hair bundles 6 with an inclination angle θ of more than 0 ° and less than 20 ° are spirally implanted. The number of these arrays is not particularly limited, and is appropriately selected according to the object to be cleaned and the object to be sorted.

  Next, the flock hole 5 of the roll brush 2C has an inclination angle θ in the axial direction of both end portions of the roll brush 2C of 0 °. Further, the flocking hole 5 of the roll brush 2C has a reverse inclination angle θ in the axial direction other than both end portions of the roll brush 2C in the range where the absolute value alternately exceeds 0 ° and less than 20 ° for each flocking hole. It is formed. As used herein, the “reverse direction” is most preferably symmetrical with respect to the vertical direction (see direction D in FIG. 2C) in front view of the roll brush 2 </ b> C, but is not limited thereto. In addition, since it is the same as that of roll brush 1A-1C about the other structure of roll brush 2A-2C, it replaces with description of roll brush 2A-2C with the description.

(Roll brush 3A, 3B: 2D flocking)
All of the flock holes 5 of the roll brush 3A have an inclination angle α in the circumferential direction of the roll brush of more than 0 ° and less than 20 °, and an inclination angle θ in the axial direction of 0 °. The flock hole 5 of the roll brush 3B gradually changes in the range where the roll brush has an inclination angle α in the circumferential direction of 0 ° or more and less than 20 °, and the inclination angle θ in the axial direction is 0 °. In addition, since it is the same as that of roll brush 1A-1C about the other structure of roll brush 3A, 3B, it replaces with description of roll brush 3A, 3B with the description.

(Roll brush 4A, 4B: Spiral flocking of irregular formula)
The flocking hole 5 of the roll brush 4A has an inclination angle α in the circumferential direction of the roll brush of 0 °, and the inclination angle θ in the axial direction of the roll brush 4A is an absolute value alternately for each flocking hole. In the reverse direction in the range of more than 0 ° and less than 20 °.
The flock hole 5 of the roll brush 4B has an inclination angle α in the circumferential direction of the roll brush of 0 ° and gradually changes in a range where the inclination angle θ in the axial direction is 0 ° or more and less than 20 °. In addition, since it is the same as that of roll brush 1A-1C about the other structure of roll brush 4A, 4B, it replaces with description of roll brush 4A, 4B with the description.

  In the conventional roll brush, since the above-mentioned inclination angle α and inclination angle θ of the flocking hole were 0 °, the contact of the brush hair with the object to be cleaned was too strong, and the object to be cleaned was damaged or operated in that state. As a result, there was a problem that the brush hair remained bent. However, according to the roll brush 1A and the like according to the present embodiment, the flock holes 5 are inclined at a predetermined angle in the circumferential direction and / or the axial direction. Therefore, the bristle bundle 6 can also be inclined in the same circumferential direction and / or axial direction. Therefore, according to the roll brush 1A and the like according to the present embodiment, since the brush bristle bundle 6 is inclined in the circumferential direction and / or the axial direction, the contact with the object to be cleaned can be made soft, and the object to be cleaned A gap between roll brushes provided to sandwich an object can be narrowed. Thus, since the space | interval between roll brushes can be narrowed, cleaning power can be improved and cleaning time can also be shortened. Therefore, it is possible to improve the transportability of the object to be cleaned.

(Brush hair 6a wire)
As a wire of brush hair 6a, any 1 type chosen from the following fibers, or 2 or more types is used in combination.
(1) Nylon (6 nylon, 66 nylon, 66 nylon wave, 610 nylon (manufactured by Toray), 612 nylon (manufactured by DuPont)) (diameter 0.05 to 2.5 mm). Nylon has the most excellent wear resistance, elasticity, and flexibility among chemical fibers, and has excellent durability. Therefore, it is suitable for washing or sorting agricultural products or industrial products.
(2) Nylon with abrasives (Tinex A (manufactured by DuPont), Tregrit (manufactured by Toray), Sangrit (manufactured by DuPont)) (diameter 0.40 to 1.30 mm, and silicone carpalite abrasive grains 60c to 600c Or AL abrasive grains 400-600AL). Nylon with abrasive is a wire processed by mixing alumina oxide and silicon carpallite as an abrasive and processed as a filament. It has excellent polishing power and exhibits the same properties as nylon. Suitable for product cleaning and sorting.

(3) Polypropylene (diameter 0.05 to 2.0 mm). Polypropylene is light in chemical fiber (specific gravity 0.91), relatively strong in both acids and alkalis, insoluble in common solvents, harder than nylon, strong in elasticity, elastic and resilient On the other hand, the tip of the hair causes a longitudinal tear during use, and wear may be accelerated. Therefore, washing and sorting of agricultural products or industrial products are suitable for use.
(4) Vinyl chloride (diameter 0.05-0.70 mm). Vinyl chloride has strong bristle and is excellent in alkali resistance and chemical resistance, but is weak in temperature, has poor elasticity recovery, and wears quickly. Therefore, it is suitable for washing or sorting agricultural products or industrial products.

(5) Polyethylene terephthalate (diameter 0.10 to 0.50 mm). As a use, washing and sorting of agricultural products or industrial products are suitable.
(6) Hard steel wire (carbon content 30C-80C, diameter 0.10-0.90mm). Hard steel wire is advanced by cold drawing and is harder than chemical fibers and animal and plant fibers, and has strong fur, but rusting occurs or breaks due to metal fatigue when used continuously. Therefore, washing and sorting of agricultural products or industrial products are suitable as applications.
(7) Stainless steel wire (diameter 0.05 to 0.55 mm). Stainless steel wire is strong in acid resistance, alkali resistance, and heat resistance, and does not generate rust and has less breakage than hard steel wire. Therefore, it is suitable for washing or sorting agricultural products or industrial products.

(8) Brass wire (diameter 0.10-0.40 mm). The brass wire is softer and softer than the hard steel wire and stainless steel wire, but has a color, so that it is suitable for washing and sorting agricultural products or industrial products.
(9) Tetron (registered trademark) (diameter: 0.10 to 0.40 mm). Tetron is superior in acid resistance to nylon and has the same level of wear resistance, durability and heat resistance as nylon, and therefore is suitable for washing or sorting agricultural products or industrial products.
(10) Conductive raw materials (Monoate (nylon system: manufactured by Nihon Unit), Elebai (nylon system: manufactured by Nihon Unit)). Since the conductive raw material does not cause static electricity because carbon is mixed, cleaning and sorting of agricultural products or industrial products are suitable for use.

(11) Acrylonitrile copper sulfide composite (Sunderlon (registered trademark) (diameter: 0.03 to 0.10 mm). The wire made of acrylonitrile copper sulfide composite is excellent in conductivity but is in the form of a thin thread. As an application, washing and sorting of agricultural products or industrial products are suitable.
(12) Kanegoto (diameter 0.01-0.10 mm).
(13) Animal fiber (horse hair, pig hair, goat hair). Horse hair is softer than chemical fibers and has a slightly stronger chemical resistance, so it is suitable for cleaning. Pig hair is harder than horse hair and has strong fur, but its length is limited. Therefore, it is suitable for washing or sorting agricultural products or industrial products. Since goat wool is softer and softer than horse hair and pork hair, it is suitable for washing and sorting agricultural products or industrial products.

(14) Plant fiber (Pakkin (Tampico)). Since the packing contains water, the cleaning effect is good, but since the breakage and wear are severe, washing and sorting of agricultural products or industrial products are suitable for use.
(15) Heat-resistant material (polyphenylene sulfide (PPS)) (diameter 0.2 to 1.5 mm).

(Substrate 2 material)
The material of the substrate 2 includes (1) ABS resin excellent in impact resistance, (2) high-density polyethylene, (3) non-reinforced polypropylene, (4) impact-resistant polystyrene / general-purpose polystyrene, and (5) hard chloride. Vinyl resin, (6) non-reinforced polycarbonate, and (7) polyacetal are preferably used.

Examples of the present invention and comparative examples will be described.
(Production of roll brush)
As shown in Table 1, roll brushes according to Examples 1 to 3 and Comparative Examples 1 to 3 were produced. The production procedure is a procedure in which a roll brush substrate is produced and flocked. Details of the procedure are shown below.
(1) Production of roll brush substrate (1-1 to 1-6).

The center of 66 nylon brush hair (0.5 mm diameter) bundled with a stainless steel round wire so that it can be processed to a planting length of 50 to 150 mm (see Table 1 below) (hereinafter simply referred to as “brush hair bundle”) ) Was implanted into the flocked hole formed in the step (1-6) using an automatic flocking machine. The inclination angle α and the inclination angle θ of the flock hole are as shown in Table 1. Accordingly, the inclination angle α and the inclination angle θ of the bristled brush hair bundle are substantially the same.

  The roll brushes used in the examples and comparative examples are all made of foamed resin HIPS whose substrate material is produced in the above process (impact resistance by adding rubber to amorphous, colorless and transparent general-purpose polystyrene with a polymer of styrene only. The impact diameter polystyrene and polybutadiene / styrene polymer with the properties of 95 parts by weight and 5 parts by weight of pigment are used as the raw material and are foamed 2.0 times, and the outer diameter is 90 mm. The flock holes formed were (hole diameter, depth) = (5 mm, 10 mm). Moreover, as for the roll brush used by the Example and the comparative example, as for the material of the brush hair, all consisted of 66 nylon, and the brush length was 90 mm (it is the length after folding). The number of brush hairs constituting the bristle bundle (the number not counting the number of turns) is due to the automatic flocking machine and has some variations, but as shown in Table 1 according to the flocked hole diameter.

  Table 2 shows the inclination angle α and inclination angle θ of the roll brush according to the example and the comparative example, the flocked state of the roll brush, and the results.

(Verification)
Since the roll brush produced in Examples 1-6 set the inclination | tilt angle (alpha) and / or inclination | tilt angle (theta) to the predetermined range, it was able to endure practical use. On the other hand, Comparative Example 1 was not inclined at all, so that the object to be cleaned was damaged during use. Moreover, since the roll brush produced in Comparative Examples 2 and 3 had an inclination angle α and / or an inclination angle θ of 20 °, the roll brush was not able to withstand practical use because cracks occurred during flocking onto the brush substrate. Therefore, it has been found that both the inclination angle α and / or the inclination angle θ are preferably less than 20 °, and more preferably 15 ° or less.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made.

  In the roll brush according to the present invention, the inclination angle of the flock hole in the circumferential direction of the roll brush and / or the inclination angle in the axial direction is within a predetermined angle range, so that the contact with the object to be cleaned is made soft. The gap between the roll brushes provided so as to sandwich the object to be cleaned can be narrowed, the cleaning power can be increased, the cleaning time can be shortened, and the transportability of the object to be cleaned can be improved. Therefore, it is very suitable for washing or sorting agricultural products or industrial products, and has high industrial applicability.
