[Technical field]

[0001] The present invention relates to a bamboo powder manufacturing device for obtaining bamboo powder by cutting bamboo positioned on a work table with rotary cutting teeth. [Background technology]

[0002] Recently, in order to deal with abandoned bamboo forests and to make effective use of bamboo, it has been proposed to crush bamboo and mix the resulting bamboo powder into edible products to make it into a health food, or to ferment it with microorganisms to make it into feed or fuel. Therefore, in order to easily obtain high-quality bamboo powder, the applicant has proposed a bamboo powder manufacturing device that uses a motor to rotate rotary cutting teeth and feeds bamboo in the longitudinal direction against the rotating rotary cutting teeth to crush it and obtain the desired bamboo powder (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2003-236403 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, while conventional bamboo powder manufacturing devices can easily produce high-quality bamboo powder, they require the bamboo stalks to be positioned on the work table one by one and cut one by one, and in order to produce a large amount of bamboo powder, the device must be operated for a long time to perform the cutting process. In addition, conventional bamboo powder manufacturing devices have the disadvantage that the dead space on the work table becomes relatively large because the rotary cutting teeth are rotated and driven in the almost central area of ​​the work table, and each bamboo stalk is positioned and fed longitudinally against the rotary cutting teeth for cutting.

[0005] The present invention has been made in consideration of the above circumstances, and aims to provide a bamboo powder manufacturing device that can simultaneously produce large amounts of bamboo powder and effectively utilize dead space on the work table. [Means for solving the problem]

[0009] The invention described in claim 4 is characterized in that, in the bamboo powder manufacturing apparatus described in claim 1, the drive source comprises a motor having an output shaft extending in a direction approximately perpendicular to the work table and capable of being rotatably driven, and multiple stacked circular cutting teeth are attached to the output shaft to form the rotating cutting teeth.

[0010] The invention described in claim 5 is characterized in that, in the bamboo powder manufacturing device described in claim 4, the work tables are formed in multiple tiers in the vertical direction, the output shaft extends in the vertical direction across each work table, and multiple work areas are formed on each work table.

[0011] The invention described in claim 6 is characterized in that, in the bamboo powder manufacturing apparatus described in claim 5, the work tables formed in multiple tiers are each covered with a cover and each is connected to an exhaust duct capable of discharging the produced bamboo powder. Effect of the Invention

[0012] According to the invention of claim 1, the work table has multiple working areas around the rotary cutting teeth, and positioning means is formed in each working area, so that bamboo positioned by each positioning means can be simultaneously cut by the rotary cutting teeth.This makes it possible to obtain a large amount of bamboo powder at the same time and to effectively utilize the dead space on the work table.

[0013] According to the invention of claim 2, a cover is provided to cover multiple working areas of the work table, so that the bamboo powder obtained by cutting processing using the rotary cutting teeth can be prevented from scattering outside the working area, and the obtained bamboo powder can be easily collected.

[0014] According to the invention of claim 3, the positioning means has a longitudinal positioning portion that abuts against the tip of the bamboo on the work table to position the bamboo in the longitudinal direction, and a radial positioning portion that abuts against the side of the bamboo on the work table to position the bamboo in the radial direction, and since these longitudinal positioning portion and radial positioning portion are attached to each working area, the bamboo can be reliably positioned in each working area, and the bamboo can be reliably cut using the rotating cutting teeth.

[0015] According to the invention of claim 4, the drive source consists of a motor having an output shaft that extends in a direction approximately perpendicular to the work table and can be rotatably driven, and multiple circular cutting teeth are stacked and attached to the output shaft to form the rotating cutting teeth, so that the number and type of cutting teeth attached to the output shaft can be appropriately changed depending on the diameter and hardness of the bamboo, etc.

[0016] According to the invention of claim 5, the work tables are formed in multiple tiers in the vertical direction, and the output shaft extends vertically across each work table, so that multiple work areas are formed on each work table, thereby making it possible to obtain a larger amount of bamboo powder at the same time and to make the size of the bamboo powder obtained on each tier of work tables different from each other.

[0017] According to the invention of claim 6, the work tables formed in several stages are each covered with a cover and each connected to an exhaust duct that can discharge the bamboo powder obtained, so the bamboo powder obtained at each stage can be collected at each exhaust duct. Therefore, if the bamboo powder obtained at each stage of the work tables is made to have different sizes, it is possible to collect the bamboo powder while avoiding the bamboo powder of different sizes from being mixed together.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The bamboo powder manufacturing apparatus of this embodiment is for obtaining bamboo powder by cutting bamboo positioned on a work table using rotary cutting teeth, and as shown in Figures 1 to 3, is equipped with a work table 1, rotary cutting teeth 2, a longitudinal positioning section 3 and a radial positioning section 4 as positioning means, a rotation device 5 (see Figure 7), a motor M as a drive source, a cover K, and an exhaust duct G.

[0020] The work table 1 is made of a plate-like member on which the bamboo W to be processed is placed, and is attached to a base F of a predetermined height. The rotary cutting teeth 2 are located in the central area of ​​the work table 1, and as shown in Figures 2 and 7, it has multiple (four in this embodiment) work areas (A-D) around the rotary cutting teeth 2. Each work area (A-D) is fitted with a positioning means (longitudinal positioning portion 3 and radial positioning portion 4) and a placement plate 1a on which the bamboo W to be processed is placed.

[0021] The rotary cutting teeth 2 is made of a disk-shaped cutting tool that is rotated by a motor M (drive source) to cut the bamboo W, and the rotary shaft (output shaft Ma of the motor M) is formed in a direction approximately perpendicular to the work table 1. More specifically, as shown in Figures 1 and 3, the motor M has an output shaft Ma that extends in a direction approximately perpendicular to the work table 1 and can be rotated, and the rotary cutting teeth 2 is configured by attaching multiple stacked disk-shaped cutting teeth 2a to the output shaft Ma, as shown in Figure 6.

[0022] Each cutting tooth 2a has a plurality of cutting edges n formed on its periphery, and a through hole 2b through which the output shaft Ma can be inserted is formed in its center. The cutting teeth 2a are stacked, and the output shaft Ma of the motor M is inserted through the through hole 2b of each cutting tooth 2a to connect them, thereby forming a rotary cutting tooth 2 with the output shaft Ma as the rotation shaft. As shown in Fig. 3, a bearing m (such as a ball bearing or a needle bearing) is attached to the tip of the output shaft Ma, enabling the output shaft Ma to be smoothly rotated.

[0023] The positioning means is attached to each of the working areas (A-D) and is used to position the bamboo at a prescribed position in each working area (A-D) on the working table 1 for cutting by the rotary cutting teeth 2, and is comprised of a longitudinal positioning section 3 and a radial positioning section 4. The longitudinal positioning section 3 is made of a plate-like member fixed to the working table 1 and, as shown in Figures 1 and 2, is erected at a position to the side of the rotary cutting teeth 2, with one end section abutting against the tip of the bamboo W placed on the mounting plate 1a on the working table 1 to position the bamboo in the longitudinal direction.

[0024] In addition, the radial positioning portion 4 has one end which abuts against the side of the bamboo W placed on the mounting plate 1a on the work table 1 to position the bamboo W in the radial direction, and as shown in Figures 4 and 5, is configured to have a first abutment portion 4a which abuts against one side of the bamboo W, a second abutment portion 4b which abuts against the other side of the bamboo W, and a spring S which urges the first abutment portion 4a and the second abutment portion 4b in a direction approaching the work table 1.

[0025] However, the radial positioning portion 4 in this embodiment is biased by a spring S and is capable of swinging around an axis L. When positioning a bamboo W with a large diameter, as shown in Figure 4, the first abutment portion 4a and the second abutment portion 4b abut against the two side surfaces of the bamboo W with a large diameter by the biasing force of the spring S, thereby positioning it radially. When positioning a bamboo W with a small diameter, as shown in Figure 5, the first abutment portion 4a and the second abutment portion 4b abut against the two side surfaces of the bamboo W with a small diameter by the biasing force of the spring S, thereby positioning it radially.

[0026] Therefore, because each radial positioning part 4 in the working areas (A to D) is elastically supported by the spring S, even if the diameters of the bamboo W to be cut in each working area (A to D) are different, the radial positioning can be reliably performed according to the size of the diameter of the bamboo W. As a result, bamboos W with different diameters can be cut simultaneously in each working area (A to D), improving work efficiency.

[0027] The cover K is a box-shaped member that collectively covers multiple work areas (A-D) of the work table 1, and its internal space is where the bamboo W is cut using the rotary cutting teeth 2. The cover K according to this embodiment has a motor M attached to its top surface and an exhaust duct G attached to its side. The exhaust duct G communicates with the inside of the cover K and is connected to suction means (negative pressure generator, etc.) (not shown), so that the bamboo powder obtained by cutting the bamboo W with the rotary cutting teeth 2 can be collected by sucking it up.

[0028] 7, the rotating device 5 supports and rotates one end of the bamboo W placed on the mounting plate 1a of the work table 1, while pressing the bamboo W in the longitudinal direction to continuously cut the bamboo W with the rotary cutting teeth 2. That is, the bamboo W as the workpiece is supported at one end on the mounting plate 1a of the work areas (A to D) and at the other end by the rotating device 5, and during cutting, the rotating device 5 rotates each of the bamboo W in each work area (A to D) and presses them in the longitudinal direction to cut the bamboo W with the rotary cutting teeth 2, so that multiple bamboo W (four in this embodiment) can be cut simultaneously to obtain a large amount of bamboo powder.

[0029] According to the above embodiment, the work table 1 has multiple working areas (A to D) around the rotary cutting teeth 2, and positioning means (longitudinal positioning portion 3 and radial positioning portion 4) are formed in each working area (A to D). Therefore, the bamboo W positioned by each positioning means can be simultaneously cut by the rotary cutting teeth 2. This makes it possible to obtain a large amount of bamboo powder at the same time and makes effective use of the dead space on the work table 1 (especially the space around the rotary cutting teeth 2).

[0030] In addition, the cover K that covers the multiple work areas (A-D) of the work table 1 prevents the bamboo powder obtained by the cutting process with the rotary cutting teeth 2 from scattering outside the work areas (A-D), and the obtained bamboo powder can be easily collected. Furthermore, the motor M can be attached to the upper surface of the cover K, and the cover K can function as a mounting member for the motor M.

[0031] Furthermore, the positioning means of this embodiment has a longitudinal positioning section 3 that abuts against the tip of the bamboo W on the work table 1 to position the bamboo W in the longitudinal direction, and a radial positioning section 4 that abuts against the side of the bamboo W on the work table 1 to position the bamboo W in the radial direction, and since these longitudinal positioning sections 3 and radial positioning sections 4 are attached to each working area (A to D), the bamboo W can be reliably positioned in each working area (A to D), and the cutting process of the bamboo W can be reliably performed by the rotating cutting teeth 2.

[0032] In addition, according to this embodiment, the driving source for driving the rotary cutting teeth 2 consists of a motor M having an output shaft Ma that extends in a direction approximately perpendicular to the work table 1 and can be rotated, and the rotary cutting teeth 2 are formed by stacking multiple disc-shaped cutting teeth 2a and attaching them to the output shaft Ma, so that the number and type of cutting teeth 2a attached to the output shaft Ma can be appropriately changed depending on the diameter and hardness of the bamboo W, etc.

[0033] Next, a bamboo powder manufacturing device according to another embodiment of the present invention will be described. As shown in Fig. 8, the bamboo powder manufacturing device according to this embodiment has multiple work tables 1 (five in this embodiment) formed in the vertical direction, and the output shaft Ma of the motor M is vertically extended across each work table 1, with multiple work areas (A to D) formed on each work table 1. Note that the same components as those in the previous embodiment are given the same reference numerals, and detailed explanations thereof will be omitted.

[0034] A motor M as a drive source is attached to the top surface of the cover K covering the topmost work table 1, and an output shaft Ma extends downward from the motor M to the bottommost work table 1, with rotary cutting teeth 2 attached to the central region of each work table 1. In this embodiment, a cylindrical collar member is attached to the outer periphery of the output shaft Ma located between the rotary cutting teeth 2.

[0035] In this way, the work tables 1 are formed in multiple tiers in the vertical direction, and the output shaft Ma extends vertically across each work table 1, and multiple work areas (A to D) are formed on each work table 1, so that a larger amount of bamboo powder can be obtained simultaneously and the size of the bamboo powder obtained on each tier of work tables 1 can be made different from each other.

[0036] Furthermore, the work tables 1 formed in multiple stages are each covered with a cover K, and each is connected to an exhaust duct G that can discharge the bamboo powder obtained. As a result, the bamboo powder obtained at each stage can be collected in each exhaust duct G, so that if the bamboo powder obtained at each stage of the work tables 1 is made to be different in size, it can be collected while avoiding the bamboo powder of different sizes from being mixed together.

[0037] Although the present embodiment has been described above, the present invention is not limited to this. For example, two, three, or five or more work areas may be formed on the work table 1, and positioning means may be attached to each work area, and the bamboo W positioned in each work area may be simultaneously cut and processed by the rotary cutting teeth 2 located in the central area to obtain bamboo powder. In another embodiment, the work table 1 is formed in five levels vertically, but it may be formed in a number of levels other than five. The positioning means for the bamboo W to be processed is not limited to the one equipped with the longitudinal positioning portion 3 and the radial positioning portion 4 as in this embodiment, and may be of another form. [Industrial Applicability]

[0038] The present invention can also be applied to devices with different external shapes or devices with added functions, etc., so long as they have the same gist as the present invention. [Explanation of symbols]
