Description

  The present invention relates to a bamboo chip making apparatus and a bamboo chip making method for converting bamboo material into chips.

  Biomass as a substitute for conventional fossil fuels has recently attracted attention toward a low-carbon society, and research in this field is progressing. Among these biomass materials, the effectiveness of bamboo materials has been generally attracting attention, and application development for industrial products has recently been advanced.

  Indispensable for the effective use and development of this bamboo is the cost reduction of the bamboo material, and the biggest bottleneck is due to the poor work efficiency from bamboo material to the first chip processing It is. It can be said that cost reduction by improving work efficiency from bamboo material to chip is an indispensable issue in promoting effective use of bamboo.

  In order to make effective use of the fiber strength of bamboo, it is indispensable to mass-produce and process approximately 3-4 cm square bamboo chips from bamboo material, but such processing technology has not yet been established. Therefore, it is one of the factors that bamboo fiber is not used on a large scale.

  As a general bamboo chip making apparatus, there is known a method of supplying to a chipper apparatus while holding one by one manually. However, the size of the chip produced by this method has a large variation, and there is a problem that only a long and thin linear chip or a mixture containing powder can be produced. In addition, this method is labor intensive, requiring labor costs, and is also one of the causes of high costs due to low productivity. Further problems are that the working environment is poor due to the cracking and breaking noise of bamboo when making bamboo chips, and that the tool life is as short as about 40 hours. It was a big bottleneck to promote utilization.

  As a conventional method other than the above, when processing a bamboo chip of about 3 cm square from a bamboo material, the supplied bamboo is first crushed from the side through a compression roller and divided in the longitudinal direction, and then 2 on the circumference. There is an example in which cutting is performed by a disk-type chipper device in which a straight blade is fixed at a location. However, even in this method, there is a problem that the life of the straight blade is as short as about 40 hours, the noise during processing is as large as 95 db or more, and the production quantity is low.

  In this way, as a method of making bamboo chips, all the conditions that 3-4 cm square bamboo chips for papermaking pulp materials, etc. are small in size, have high production capacity, and can be automatically produced with low noise. There was no satisfactory device.

The rear views showing the supply guide 20 are respectively shown. As shown in the schematic plan view of FIG. 1, the bamboo chip making apparatus 100 includes a bamboo stocker unit 10, a supply guide 20, and a cutting area. A certain number of bamboo materials BM held by the bamboo stocker unit 10 are sent to the supply guide 20 and further supplied to the cutting area. In the cutting area, a ring cutting section 30 and a divided cutting section 40 are provided. As shown in the schematic diagram of FIG. 2, the bamboo material BM is first sent from the supply guide 20 to the ring cutting unit 30, and the bamboo material BM is cut into a ring shape with a certain width to form a bamboo ring RM. Further, the bamboo ring RM is sent to the division cutting unit 40 and divided into bamboo chips CM cut in an arc shape with a central angle as a constant angular width.
(Bamboo stocker part 10)

  As shown in the plan views of FIGS. 1 and 7, the bamboo stocker unit 10 holds a plurality of cylindrical bamboo materials BM. Here, a plurality of square bars 12 are arranged in parallel and face the side surface of the supply guide 20. The interval between the square members 12 is made narrower than the length of the bamboo material BM supplied here. The bamboo material BM is supplied in a posture perpendicular to the extending direction of the square member 12. In addition, it can replace with a square material and can also be set as a flat bamboo stocker part.

  Further, as shown in the rear view of FIG. 5 and the perspective view of FIG. 6, the bamboo stocker unit 10 is held in an inclined posture so as to have a downward slope toward the feeding direction of the bamboo material BM, that is, toward the supply guide 20.

The bamboo stocker unit 10 can also be fixed in an inclined posture. Moreover, you may make it movable so that the bamboo stocker part 10 can change from a horizontal state to arbitrary inclination angles. According to this method, when the bamboo material BM is supplied to the bamboo stocker unit 10, the inclination angle is made horizontal or shallow so that the operator can easily set the bamboo material BM in the bamboo stocker unit.
(Feeding mechanism)

Further, a feeding mechanism is provided at a boundary portion between the bamboo stocker unit 10 and the supply guide 20 so that a predetermined number of bamboo materials BM are supplied from the bamboo stocker unit 10 to the supply guide 20. Specifically, when the bamboo material BM is sent to the supply guide 20 by a predetermined number, the gap between the supply guide 20 and the bamboo stocker unit 10 is blocked to prevent further bamboo material BM from being sent out.
(Stationary part 14)

For the feed mechanism, for example, a configuration in which the stationary portion 14 protrudes from between the square members 12 below the bamboo stocker portion 10 can be used. In the example of FIG. 8, the stationary portion 14 is formed in a claw shape, and is projected when the four bamboo materials BM are delivered to the supply guide 20, and the bamboo material BM is further supplied from the bamboo stocker portion 10. Suppresses moving to 20.
(Supply guide 20)

The supply guide 20 guides the bamboo material BM delivered from the bamboo stocker unit 10 to the ring cutting unit 30. In the example of the plan view of FIG. 1, four V blocks 22 in which a metal plate is bent in a V shape are arranged in parallel so as to hold four bamboo members BM.
(Guide tilt mechanism 24)

  Further, the supply guide 20 is provided with a guide tilt mechanism 24 that can be tilted from a horizontal posture to an inclined posture that is a downward slope toward the ring cutting section 30 side. The guide tilt mechanism 24 holds the supply guide 20 in a substantially horizontal posture as shown in FIG. 3 when the bamboo material BM is conveyed from the bamboo stocker unit 10 to the supply guide 20. Then, when the bamboo material BM is held in each V block 22, the supply guide 20 is inclined by the guide inclination mechanism 24 as shown in FIG. 4, and each bamboo material BM is cut into a circular shape by sliding down the inclined surface in the length direction. It is moved to the cutting unit 30 side. As described above, the bamboo material BM rolls in a direction substantially perpendicular to the length direction due to the inclination and is moved from the bamboo stocker unit 10 to the supply guide 20 and further moved to the cutting area so as to slide down in a direction parallel to the length direction. Is done. By adopting such a movement method using the weight of the bamboo material BM due to the inclination, there is no need to separately provide a transport mechanism for the bamboo material BM, and an advantage that the configuration can be simplified can be obtained. The inclination angle is set to, for example, 10 ° to 40 °, or 20 to 30 °, preferably 25 ° in consideration of the weight of the bamboo BM, the friction coefficient with the supply guide 20, and the like.

Here, the guide tilt mechanism 24 is pushed up by the pneumatic cylinder and moved to the tilted posture. The guide tilt mechanism 24 is configured to detect that the bamboo material BM is held in each V block 22 and automatically tilt the supply guide 20 from the horizontal posture. For this purpose, each V block 22 is provided with a sensor and a micro switch for detecting that the bamboo material BM is held.
(Cutting area)

The cutting area includes a ring cutting section 30 and a divided cutting section 40. The bamboo material BM is sequentially cut into chips.
(Round cut section 30)

The ring cutting section 30 cuts into a ring shape with a certain width from the tip of the bamboo material BM. Here, the ring cutting section 30 has a plurality of circular saw shapes. Here, as shown in the schematic cross-sectional view of FIG. 9, the bamboo ring RM is formed by cutting the four bamboo materials BM into circles using the circular saw teeth 32 which are two circular saw-shaped cutting portions. Further, the bamboo material BM is cut into a circular shape so that the circular sawtooth 32 is inserted between the bamboo materials BM. Thereby, several bamboo material BM can be cut | disconnected on a ring cut simultaneously and reliably.
(Moving plate 34)

Moreover, the circular sawtooth 32 presses a tooth | gear from the upper direction of the bamboo material BM, and cuts it from the top to the bottom. As a result, the cut bamboo ring RM drops downward and is sent to the divided cutting portion 40 side. As shown in the perspective views of FIGS. 6 and 10, the circular saw blade 32 is fixed to the moving plate 34. By moving the moving plate 34 up and down, the circular saw blade 32 fixed to the moving plate 34 also moves up and down. Moved. The moving plate 34 is also moved up and down by a pneumatic cylinder or the like. In this example, the circular cutting section 30 is formed in a circular saw shape. However, the present invention is not limited to this configuration. For example, a chain saw-shaped flat tooth 232 is used as in the bamboo chip making apparatus 200 according to the second embodiment shown in FIG. It is also possible to cut it.
(Pressing plate 36)

  Further, a pressing plate 36 for holding the bamboo material BM is provided at the time of cutting by the ring cutting unit 30. As shown in the perspective view of FIG. 10, the pressing plate 36 is pressed from the upper surface of the bamboo material BM held by the V block 22 to sandwich the bamboo material BM with the V block 22. As a result, a situation in which the bamboo material BM is exposed during the cutting by the ring cutting section 30 can be avoided, and the ring cutting can be performed stably. The pressing plate 36 is also fixed to the moving plate 34 and is moved up and down by a cylinder or the like.

Prior to cutting by the circular saw blade 32, the pressing plate 36 is lowered to press and hold the bamboo material BM. When the circular saw blade 32 is raised after the circular saw blade 32 is lowered and the bamboo ring RM is cut, the pressing plate 36 is also raised. As described above, the vertical movement of the pressing plate 36 is interlocked with the vertical movement of the circular saw blade 32 and is designed to be lowered before the circular saw blade 32 is lowered.
(Holding part 38)

The bamboo ring RM cut into a ring by the ring cutting unit 30 is dropped downward and temporarily held by the holding unit 38. As shown in the perspective views of FIGS. 12 and 13 and the schematic views of FIGS. 14 and 15, the holding portion 38 has a curved surface or an inclined surface along the circumference so as to hold the lower surface of the bamboo ring RM. It is. In the example of FIG. 14 and the like, the holding portion 38 holds only the bottom surface, but may be configured to hold the side surface of the bamboo ring RM. For example, a wall is made upright vertically along both sides of the bamboo ring RM to form a holding portion.
(Division cutting unit 40)

The bamboo ring RM held by the holding unit 38 is divided into chip-like bamboo chips CM by the division cutting unit 40. As shown in the front view of FIG. 16A, the divided cutting unit 40 is provided with a frame 43 having an arc shape when viewed from the front, and a plurality of divided cutting blades 42 radially from a central axis 41 at a certain angle. The shape is arranged. Further, as shown in the cross-sectional view of FIG. 16B, the divided cutting blade 42 has a substantially triangular shape that is inclined so as to be wider toward the center in a side view and narrower toward the circumference. By doing in this way, it can cut | disconnect from an inner side to an outer side by pressing the bamboo ring RM, and it can make it easy to cut | disconnect and divide | smooth smoothly as the bamboo ring RM is broken.
(Extruded part 50)

  Moreover, the extrusion part 50 for extruding the bamboo ring RM with respect to the division | segmentation cutting part 40 is provided. As shown in the side view of FIG. 15 and the plan view of FIG. 17, the extruding unit 50 presses the bamboo ring RM held by the holding unit 38 against the divided cutting unit 40 from the back surface, and divides it into chips. The extruding part 50 has a disk-like pressing surface so that the back surface of the bamboo ring RM can be pressed, and is pushed out in a piston manner. Further, in order to cut the bamboo ring RM into a plurality of bamboo chips CM at once, a pressing force having an instantaneous force is applied to the pushing portion 50. After pressing, the extruding part 50 is pulled in to prepare for the next pressing. Moreover, when it cannot divide into bamboo chip | tip CM at once, it tries to press the extrusion part 50 again. In this example, it is set so that it is detected that the division of the bamboo chip CM is not completed and the pressing of the pushing portion 50 is repeated up to four times.

  Further, since the bamboo ring RM is extruded by the extruding unit 50 and cut by the divided cutting unit 40, the bamboo ring RM held by the holding unit 38 and the divided cutting unit 40 are arranged so as to be substantially coaxial. Here, the height and position of the holding portion 38 are adjusted so that the height of the divided cutting portion 40 and the height of the bamboo ring RM coincide with each other and the central axes substantially coincide.

  This division cutting part 40 sets the center angle which provides the division cutting blade 42 according to the magnitude | size of the required bamboo chip | tip. The smaller the central angle, the smaller the bamboo chip, and the larger the central angle, the larger the bamboo chip. On the other hand, the smaller the central angle is, the more the pressing force by the extruding unit 50 is required. Taking these into account, the central angle is set. For example, the central angle is set to 15 ° to 45 °, preferably 20 ° to 40 °, more preferably 30 °. Needless to say, a plurality of divided cutting portions 40 having different center angles can be prepared and exchanged depending on the application. In this way, the bamboo ring RM can be divided into bamboo chips CM into substantially equal sizes. Moreover, the outer diameter of the division | segmentation cutting part 40 is designed according to the diameter of the bamboo ring RM, ie, the bamboo material BM. In this example, it is designed to be compatible with a bamboo ring RM having a diameter of 50 to 150 mm, and can be applied to most bamboo materials BM.

  Thus, by providing the division cutting part 40 so that it may be located under the ring cutting part 30, the bamboo ring RM cut in a ring shape can be dropped and conveyed from the ring cutting part 30 to the division cutting part 40. In addition, by shifting the position where the ring cutting part 30 and the divided cutting part 40 are provided up and down, the bamboo material BM is fed forward to the ring cutting part 30 in the length direction when cutting the ring, while the bamboo ring RM is used when dividing the cutting. Can be arranged in the length direction of the bamboo ring RM, which is advantageous in securing a space for arranging each member.

Since the divided cutting portion 40 is in communication between the divided cutting blades 42, the bamboo chip CM divided by being pressed against the entire surface of the divided cutting portion 40 by the extruding portion 50 is separated from the back surface of the divided cutting portion 40. Discharged. Each of these bamboo chips CM is in a state of being bent like a tile as shown in FIG. In this example, it is processed into a bamboo chip CM of about 3 to 4 cm square. The obtained bamboo chip CM is stored in a bucket 61 arranged on the back side of the divided cutting portion 40 as shown in FIG.
(Conveying unit 60)

  Alternatively, a transport unit 60 for transporting the bamboo chip CM to a desired position can be further provided. For example, as shown in the side view of FIG. 19, the transport unit 60 is arranged in the shape of an inclined belt conveyor, the front end of the conveyor is disposed close to the discharge portion of the bamboo chip CM, and sequentially transports the discharged bamboo chip CM. To do. The conveyed bamboo chip CM is sent to a predetermined post-process, such as bagging in a predetermined amount.

  As described above, the bamboo material can be put into one apparatus and cut into chips. As a result, the amount of work for obtaining bamboo chips can be greatly reduced in labor compared to the conventional technique. In particular, it is possible to produce bamboo chips efficiently by saving labor significantly compared to the conventional method of obtaining bamboo chips from bamboo using multiple devices and equipment by continuously performing round cutting and chipping of bamboo. Thus, the use of bamboo chips can be expanded by reducing the production cost of bamboo chips, which is advantageous for the spread of bamboo chips. In addition, bamboo chips can be continuously produced and the production efficiency is improved by dividing the process into a plurality of processes, ie, bamboo stock, supply process, ring cutting process and split cutting process. . In addition, since a plurality of bamboo materials can be processed in parallel at the same time, the processing capability is higher than the conventional processing of one bamboo material at a time. In addition, the noise during operation is a circular saw cutting sound during circular cutting and an impact sound during split cutting, so there is no loud noise as in the past and low noise is achieved throughout the entire process. It becomes possible to configure a system that takes into account the work environment of noise.

  In addition, the produced bamboo chips can be secondarily processed to produce fibers. For example, fibers made from 3-4 cm square bamboo chips can be mixed into conventional wood pulp as a pulp material for papermaking, or mixed with MDF (medium density compressed plywood) wood material for building materials. It can be suitably used for applications that make use of the antibacterial properties and fiber strength of bamboo, such as special bamboo fiber sheets and paper products containing bamboo fibers.

  The bamboo chip making apparatus and the bamboo chip making method according to the present invention can be suitably used for a bamboo chipper or the like that can be easily chipped by introducing bamboo material.
