Description

  The present invention relates to a bone crushing apparatus for crushing human bones or animal bones.

  Conventionally, bones of animals such as human bones and pets that have been processed by cremation in a sanctuary or the like have been mainly buried in graves of temples or stored in an ossuary or the like.

  The amount of bones of animals such as human bones and pets that have been buried has increased greatly as the population and pets have increased, and with the development of urban areas due to urbanization, there are fewer places where these bones can be buried. Therefore, in order to reduce the bulk capacity of the bone, a reduction processing is performed in which the bone is manually pulverized by using tools such as a mortar and a pestle.

  In recent years, the number of people who wish to have bones has increased year by year. In order to spread human bones to mountains, rivers, seas, etc., avoid misidentification of incidents, etc. In order not to deteriorate the environment, human bones must be crushed to a predetermined size or less (2 mm or less).

  From these facts, in order to pulverize bones, especially human bones (remains) by hand, not only a great deal of labor is required, but the crushing process may be performed by the deceased's bereaved family. In many cases, it is mentally painful to crush human bones (skeletal bones) whilst mourning the death of the deceased. To solve these problems, bones that are repeatedly collided with a rotating body that rotates at high speed are crushed. A pulverizer has been proposed (see, for example, Patent Document 1).

Japanese Patent Application No. 2003-201524

  Although these bone crushing devices of Patent Document 1 are preferable because they can quickly and sufficiently crush the remains of humans and pets, in order to repeatedly collide bones with a rotating body that rotates at a high speed, pulverization, in particular, unpulverized large When a crushing noise is generated at the start of crushing when bone remains, and when crushing in the presence of the survivor, it may be painful for the survivor to hear the crushing loud sound and rotation. A large mechanical load is applied to the drive system such as the drive motor and drive shaft for driving the body and the rotating body, the wear of the rotating body and the drive system is large, and it is necessary to replace the rotating body and the drive system relatively frequently. There was a problem that there was.

  On the other hand, in order to reduce the crushing noise and the wear of the rotating body and the drive system, when the rotational speed of the rotating body is uniquely reduced, although the crushing sound and the wear of the rotating body and the drive system can be reduced, There is a problem that large unground bone remains in the crushed bone or that the pulverization process takes a very long time.

  Further, as shown in FIG. 6, button switches (SW) 61 to 77 and a touch panel 78 for an operator to change setting contents and perform various operations are provided at an upper right position toward the front of the soundproof box 19. A front operation unit 45 provided is provided, and various operation switches such as a power switch for controlling the bone crushing device 1 and a notification lamp for notifying operation status are provided inside the side surface of the soundproof box 19. A control panel 21 including an operation panel 53 is attached. In addition, a dust collector 22 is provided inside the soundproof cabinet 19, and a dust collection duct 23 attached to the dust collector 22 extends to the side of the storage body 5, and the storage body 5 is removed. By operating the dust collector 22 at times, dust generated in the container body 2 and the storage body 5 due to pulverization is sucked from the dust collection duct 23 so that dust including the remains is not scattered.

  As shown in FIG. 2, a pedestal 24 that protrudes forward is provided at the lower part on the front side of the leg 8, and a pedestal 25 is provided on the pedestal 24. The pedestal 25 can be moved in the vertical direction by driving an electric cylinder 26 attached below.

  When the storage body 5 is attached to the container body 2, the storage body 5 is placed on the base 25 with the base 25 lowered. Next, the electric cylinder 26 is driven to raise the pedestal 25 and lift the storage body 5. The upper end of the storage body 5 is brought into close contact with the lower end of the container body 2 and the spring catch 4 a is operated to fix the storage body 5 to the container body 2. Then, when the pedestal 25 is lowered in a state where the storage body 5 is fixed to the container body 2, the crushing operation can be started.

  Further, as shown in FIG. 2, when the motor 13 is driven, the swing shaft 11 is rotated via the emarmor 12. The potentiometer 15 detects the angle of the swing shaft 11, and when the swing shaft 11 is rotated 180 °, the motor 13 is temporarily stopped. At that time, the container body 2 is turned upside down, and the swing base 14, the swing shaft 11, the emarmor 12 and the motor 13 constitute the reversing mechanism as the repeated collision means of the present invention. .

  Next, the obstruction | occlusion container 6 used for the present Example is explained in full detail using FIG.3 and FIG.4. FIG. 3 is a side sectional view of the closed container 6, and FIG. 4 is a cross-sectional view taken along line AA of the closed container 6 in FIG. 3.

  As shown in FIG. 3, a servo motor 16 as a driving means is provided in the engine unit 17 fixed to the rocking table 14, and a large-diameter gear 27 and a rotating shaft directly connected to the servo motor 16 are provided. A small diameter gear 28 directly connected to the (shaft) 29 is disposed. The rotation of the servo motor 16 is transmitted by fitting the large-diameter gear 27 and the small-diameter gear 28. Therefore, when the servo motor 16 is driven, the rotating shaft (shaft) 29 is rotated at a high speed. The rotary blade 33 attached to the tip of the rotary shaft (shaft) 29 also rotates at high speed. A socket 31 is formed on the bottom surface side of the engine unit 17, and the upper end of the container body 2 is detachably attached to the socket 31 by the clamp lever 18. In this embodiment, as will be described later, since the wear of the rotor blades 33 can be reduced by keeping the rotation of the rotor blades 33 low at the start of pulverization, the replacement frequency of these rotor blades 33 can be greatly reduced. In order to facilitate the replacement of the rotor blades 33, the rotation shaft (shaft) 29 is not devised to connect a plurality of (for example, two) individual shafts, and the rotation is made in a single shape. The shaft (shaft) 29 is used, and by doing so, the generation of sound from the connecting portion of these shafts is also reduced, but the present invention is not limited to this, and these rotating shafts The (shaft) 29 may be a combination of a plurality of individual shafts.

  The container body 2 is connected to a cylindrical storage body 5 capable of storing the bone 7 by a spring catch 4a, and the bone 7 stored in the unground bone storage portion 5a constituting the storage body 5 has a swing shaft. When 11 is rotated and inverted, it is dropped by dropping into the container body 2.

  Further, a rubber packing ring 32 (not shown for the lower end of 5a) is attached on the outer periphery of the lower end of the cylindrical container body 2 and on the outer periphery of the lower end of the unground bone receiving portion 5a. The body 2 and the uncrushed bone storage portion 5a, and the uncrushed bone storage portion 5a and the ground bone storage portion 5b can be brought into close contact with each other without a gap. Therefore, the inside of the closed container 6 composed of the container body 2 and the storage body 5 is in a sealed state, and the pulverization operation can be performed without scattering the pulverized fine powder of the bone 7 to the outside.

  A rotating blade 33 as a rotating body is arranged at a substantially central position of the container body 2 having a substantially cylindrical shape so as to partition the inside of the container body 2. The length of the rotating blade 33 in the longitudinal direction is It is formed to have a length substantially inscribed in the inner surface of the body 2. Therefore, when the bone 7 collides with the rotary blade 33, it is possible to reduce the passage of the insufficiently pulverized bone 7 through the gap between the inner surface of the container body 2 and the rotary blade 33.

  Further, the inner diameter of the container body 2 in the vicinity of the position where the rotor blades 33 are provided is formed to be larger than the inner diameters of both end regions of the container body 2 and the inner diameter of the storage body 5, and the inner diameter is small. The bone 7 that has moved (dropped) from both ends of the container body 2 and from the storage body 5 is guided to the inner peripheral area of the rotary blade 33 so that it can collide with the rotary blade 33 more reliably. It has become.

  Moreover, as shown in FIG.3 and FIG.5, the container body 2 and the storage body 5 which comprise the obstruction | occlusion container 6 of a present Example are made into the double wall structure, and make between each container wall hollow. Thus, the sound pressure of the pulverized sound generated inside the container body 2 leaking out of the closed container 6 can be lowered, and the soundproof portion of the present invention is formed by the hollow double structure portion. Yes.

  In this embodiment, the hollow double structure is applied to the entire container body 2 and the storage body 5 constituting the closed container 6, and in this way, the sound leaking out of the closed container 6 is obtained. Although it is preferable because the pressure can be lower, the present invention is not limited to this. Only the vicinity of the position where the rotor blade 33 of the container body 2 where the pulverization sound is provided is provided with a hollow double. It is good also as a structure.

  Furthermore, the lid portion 34 that closes one end of the container body 2 has a substantially cylindrical projecting portion 35 formed so as to be recessed inward of the container body 2. A hollow portion 36 is formed. A rotation shaft (shaft) 29 that transmits the rotation of the servomotor 16 is inserted into the hollow portion 36. Since the rotary shaft 29 directly connected to the rotary blade 33 and the rotary shaft 29 supported on the engine unit 17 side are connected by fitting the gears 37 and 38, the container body 2 is removed from the engine unit 17. It can be easily removed.

  Moreover, the wall part of the protrusion part 35 for forming the hollow part 36 is made into the hollow double structure similarly to the outer wall of the container body 2, The soundproof part of this invention is formed by this hollow double structure. Yes.

  In addition, in this embodiment, a hollow double structure is used as these soundproof portions, but the present invention is not limited to this, and a soundproofing material or a sound absorbing material may be filled in these hollows, These soundproof portions may be formed by adhering a soundproof sheet or a sound absorbing sheet to the outer periphery or inner periphery of the container body 2 or the inner surface or outer surface of the protruding portion 35.

  A ball bearing 40 as a bearing portion is disposed on a bottom surface portion 39 that closes the distal end side of the hollow portion 36 of the protruding portion 35. Since the ball bearing 40 is disposed on the bottom surface 39 of the projecting portion 35, the rotary shaft 29 can be pivotally supported at a position closest to the rotary blade 33, and the shaft blur generated when the rotary blade 33 rotates at a high speed. Can be suppressed. In addition, since the ball bearing 40 is provided inside the hollow portion 36, it is possible to avoid a trouble caused by the crushed bone 7 entering the ball bearing 40.

  And since the hollow part 36 is formed in the protrusion part 35, while the heat which generate | occur | produced from the servomotor 16 becomes difficult to be transmitted to the inside of the container body 2, the container body 2 is metal materials, such as stainless steel. By being formed, the heat generated inside the container body 2 can be quickly radiated to the outside, so that the temperature rise inside the container body 2 can be minimized. Therefore, dust explosion due to temperature rise inside the container body 2 can be prevented.

  As shown in FIG. 4, the rotating shaft 29 is provided at the center of the circular cross section of the container body 2, and the center of the rotating blade 33 is fixed to the rotating shaft 29. The shape of the rotary blade 33 is a flat plate having a narrow width in the direction of the outer periphery of the rotation. Therefore, the rotational speed of the rotary blade 33 can be increased, and a good crushing force can be obtained. Durability can also be improved.

  By driving the servo motor 16, the rotor blades 33 can rotate at a high speed of 3000 to 9000 revolutions per minute. The rotational speed of these rotor blades 33 depends on the shape of the rotor blades 33 used, the outer diameter, and the like. As long as the rotation speed is such that the bone 7 can collide with the rotor blade 33 and be pulverized, it may be selected appropriately.

  Further, the rotating body of the present invention is not limited to the plate-shaped rotating blade 33 but may be a rod-shaped rotating body or a propeller-shaped one, or is not limited to one rotating blade 33, and a plurality of sheets. The rotary blade 33 or a multistage rotary blade 33 may be provided.

  FIG. 7 is a block diagram showing an electrical configuration of the bone crushing apparatus 1 of the present embodiment. The control panel 21 is connected to a servo motor 16 and a motor 13 as shown in FIG. A motor control circuit 52 for controlling the rotation of the servo motor 16 and the motor 13, an operation panel 53 having various operation switches such as a power switch and a notification lamp for notifying the operation status, the motor control circuit 52 and the operation Connected to the panel 53, a P-ROM for storing a control program in which the contents of a control process for controlling the entire operation of the bone crushing device 1 are stored, a control microcomputer for executing the control program, and various types executed by the control microcomputer And a main control circuit 51 including a nonvolatile memory and a volatile memory for storing various setting data. Both the electric cylinder 26, the rail motor 42, the dust collector 22 and the potentiometer 15 are connected to the main control circuit 51 via the external I / O 54. The electric cylinder 26, the rail motor 42, Various signals can be exchanged between the dust collector 22 and the potentiometer 15, and the main control circuit 51 can grasp the operation status and angle information, and the operation of these parts can be performed by outputting operation instructions. The main control circuit 51 can be controlled.

  Further, the main control circuit 51 is connected to the above-described front operation unit 45 via the communication unit 55, and the touch panel 78 (see FIG. 8) provided on the front operation unit 45 with respect to the front operation unit 45. Display contents displayed on the front operation unit 45 and various data such as setting contents received on the touch panel 78 can be received from the front operation unit 45. ing.

  As shown in FIG. 8, the front operation unit 45 used in the present embodiment has a touch panel 78 on which various settings and processing statuses can be confirmed by finger touch in an interactive format corresponding to the display contents. At the same time, the slider raising button SW61 operated when the gate door 41 is raised, the slider lowering button SW62 operated when the gate door 41 is lowered, the cylinder raising button SW63 operated when raising the pedestal 25, and the pedestal 25 are lowered. Cylinder lowering button SW64 that is operated when the dust collector 22 is operated, the dust collector operation button SW65 that is operated when the dust collector 22 is operated, the dust collector stop button SW66 that is operated when the dust collector 22 is stopped, and the automatic operation button that is operated when the automatic operation is performed. SW67, empty button SW68 to be operated when performing empty driving, resetting Provided is a reset button SW69 that is operated to stop the operation, a buzzer stop button SW70 that is operated to stop a buzzer sound (not shown) that notifies an abnormality, and an emergency stop button SW77 that is used to stop the device in an emergency. It has been.

  Below the touch panel 78, six function switches 71 to 76 F1 to F6 are provided. Of these, by operating the function switch 76 of F6, the touch panel 78 has the function switch shown in FIG. As shown in the figure, a processing content setting screen is displayed. In the processing content setting screen, the rotation of each rotary blade 33 at a low speed at the start of the grinding process, a medium speed at the middle, and a high speed at the end. The speed (the number of revolutions per minute: RPM) and the number of times of reversal of the closed container 6 (the number of times of reversal where the reversal and return to the original initial state once) are displayed at the bottom of the processing content setting screen. It can be changed and set by selecting the numeric keypad.

  Specifically, in the present embodiment, the rotational speed of the rotary blade 33 is at least 3000 rotations and at most 9000 rotations, so the rotation speed at the start of crushing is 3000 rotations that is the minimum rotation speed, The rotation speed at the end of grinding is 9000 rotations, which is the maximum rotation speed, and the medium rotation speed may be 6000 rotations that are intermediate between both rotation speeds. As for the number of reversals, if the number of times of processing at low speed is large, the time required for the pulverization processing becomes long. Therefore, it is preferable to grasp and set the standard appropriate number of conditions by several trial runs. The number of times of efficient execution is set to 2 times of inversion at low speed, and medium speed More inversions at The number, for example six times, fewer than medium speed is fast, for example, if two or three times, can be performed efficiently pulverized.

  In this way, the setting data of the rotational speed and the number of inversions of the low-speed, medium-speed, and high-speed rotating blades 33 received on the processing content setting screen is transmitted to the main control circuit 51 and updated and stored as setting data. Thus, the pulverization process is performed based on the updated setting data, and the touch panel 78 and the main control circuit 51 form the change setting means in the present invention. When a rotational speed higher than the medium speed or high speed is set as the rotational speed at low speed or medium speed, a warning is displayed, the setting is invalidated, and the setting is accepted again. That is, by the main control circuit 51 and the motor control circuit 52, the rotation speed of the rotary blade 33 at the start of the collision of the bone 7 with the rotary blade 33 is the lowest than the rotation speed of the rotary blade 33 at the time of repeated collision. The main control circuit 51 and the motor control circuit 52 form the control means in the present invention.

  In this embodiment, the rotational speed of the rotary blade 33 can be changed and set. However, the present invention is not limited to this, and the rotational speed of the rotary blade 33 is fixed in advance. It is also possible to accept only the number of inversions. By doing so, the contents to be set are limited to the number of inversions at each of the three rotation speeds of low speed, medium speed, and high speed, and the contents to accept change settings are simplified. Thus, the change setting may be easily performed.

  In addition, as a setting method, the setting content is set to “large large block” or “a large block” so that the setting when the bone has many large chunks or the bone with few large chunks can be easily selected. Select the menu by displaying the menu of “Large block” and the menu of “Bone bark” or “Bone barb” for the moisture content of the bone, and selecting the menu. For example, when the menu item “Many large chunks” is selected, the setting item is set in the menu item so that the number of inversions is one more than the normal number at a low speed. May be selected.

  The crushing operation of the bone 7 of the bone crushing apparatus 1 will be described in detail with reference to FIG. 5A and 5B are cross-sectional views showing a state in which the top and bottom of the closed container 6 are inverted.

  First, when automatic operation is started, the main control circuit 51 drives the servo motor 16 to rotate the rotating blade 33 at a low speed set, for example, 3000 rpm. When the motor 13 is driven, the swing shaft 11 starts to rotate, and when the swing shaft 11 rotates 180 °, the motor 13 is temporarily stopped. Then, as shown in FIG. 5A, the vertical position of the closed container 6 composed of the container body 2 and the storage body 5 is reversed, and the bone 7 stored in the storage body 5 is replaced with the container body 2. It falls inside and collides with the rotating blade 33 rotating at high speed. The bone 7 that has collided with the rotary blade 33 and turned into powder falls below the rotary blade 33 and is accumulated on the lid 34 side of the container body 2.

  Next, as shown in FIG. 5 (b), the main control circuit 51 reversely rotates the motor 13 and rotates the swing shaft 11 by 180 °, so that the closed container 6 is reversed and the lid portion 34 of the container body 2 is reversed. The bone 7 accumulated on the side begins to fall. Then, the bone 7 again collides with the rotary blade 33 rotating at a low speed, for example, 3000 revolutions per minute, and is accumulated on the bottom surface side of the storage body 5.

  Further, since the projecting portion 35 has a substantially cylindrical shape, the falling bone 7 is guided to the projecting portion 35, and the bone 7 can collide with the outer peripheral side where the rotational speed of the rotary blade 33 is high. it can. Since the protruding portion 35 has a tapered shape in which the outer diameter on the bottom surface 39 side is smaller than the outer diameter on the lid portion 34 side, the powdered bone 7 can be quickly dropped without retaining. .

  When the reversing operation of the upper and lower positions of the closed container 6 by the rotation of the swing shaft 11 is repeated a predetermined number of times of reversal that is set corresponding to the low speed, for example, 2 times (the reversing operation is 4 times the reversal operation). The main control circuit 51 then controls the rotation speed of the servo motor 16 to a rotation speed of, for example, 6000 rotations where the rotation of the rotor blades 33 is set to a medium speed, via the motor control circuit 52, and then at a low speed. Similarly to the above, the reversing operation corresponding to the number of reversals set corresponding to the medium speed is performed by driving the motor 13, and the rotation of the rotary blade 33 is set at a high speed after the number of reversals is completed. For example, after controlling the number of rotations to 9000 rotations through the motor control circuit 52, the motor 13 is driven to perform a reversing operation corresponding to the number of reversals set corresponding to the high speed. Rotating blade 33 Almost all the bones 7 that have been crushed once again collide with the rotating blades 33 at different rotational speeds and are crushed. As in the prior art, at the rotational speed of a single rotating blade 33, Soft bone sites, such as bone marrow, are relatively soft and may remain elastic, and these sites may not be crushed well, whereas Since the soft bone portion is crushed well at a relatively low speed, all the bones 7 having different hardness depending on the bone portion can be crushed evenly. As described above, in this embodiment, the main control circuit 51 controls the rotational speed of the rotary blade 33 based on the number of inversions of the closed container 6.

  Since the bone crushing apparatus 1 of the present invention can move the bone 7 freely within the closed container 6 simply by turning the closed container 6 upside down, the repeated collision means of the present invention is formed with a simple configuration. be able to. Further, the bone 7 can be easily crushed to a predetermined size or less (2 mm or less) by repeatedly colliding with the rotating blade 33 rotating at high speed in the closed container 6, and the predetermined Only bones having a size less than or equal to (2 mm or less) can be separated and collected in the crushed bone receiving portion 5b.

  Further, when the rotary blade 33 rotates at a high speed, the bone 7 crushed in the closed container 6 is agitated, and the bones 7 collide with each other, so that finer pulverization is possible. Furthermore, since the bone 7 can be pulverized within a short time, the pulverization operation can be completed before the dust reaches the ignition temperature, and dust explosion due to mixing of the dust and air can be prevented.

  Further, the servo motor 16 is provided with a detection sensor (not shown) for detecting a load applied to the servo motor 16 when the bone 7 collides with the rotary blade 33. When the bone 7 is crushed, the resistance applied to the rotor blade 33 is reduced and the load applied to the servomotor 16 is reduced. Therefore, the main control circuit 51 detects the load applied to the servomotor 16 by a detection sensor (not shown). Thus, the pulverization state inside the closed container 6 can be easily confirmed from the outside of the closed container 6, and when all the bones 7 have passed and the pulverization is finished, the reversal operation is immediately started or the bone pulverizer is used. 1 can be stopped, and if the bone 7 that is not sufficiently ground remains, the number of inversions can be increased to continue the grinding operation.

  After the crushing operation, the crushed and powdered bone 7 ′ passes through the stainless steel mesh 5 c and is accumulated in the crushed bone receiving portion 5 b. When recovering the bone 7 ′, as shown in FIG. 1, the electric cylinder 26 provided on the pedestal 24 is driven to raise the pedestal 25, and the gate door 41 provided on the front surface of the soundproof box 19 is moved. The opening 44 is opened by pressing the slider raising button SW61 of the front operation unit 45. Next, after removing the spring catch 4a connecting the container body 2 and the storage body 5, the gate door 41 is closed by pressing the slider lowering button SW62 of the front operation section 45. The storage body 5 can be removed from the container body 2 by lowering the pedestal 25 while operating the dust collector 22 provided inside the soundproof box 19.

  When the storage body 5 is removed from the container body 2, finely pulverized fine powder of bone 7 ′ may be scattered. The fine powder of bone 7 ′ can be collected by the dust collector 22 and the soundproof box 19. By being provided, it can be prevented from flowing out. Further, the inside of the soundproofing cabinet 19 has a double structure, and a sound deadening material is disposed in the hollow of the double structure, and in addition to preventing the outflow of dust, the crushed sound can be blocked. ing.

  Further, since the handle 2 is provided on the container body 2, the container body 2 can be removed from the engine portion 17 and easily transported. Further, the rotary blade 33 can be removed from the container body 2 so that the inside of the container body 2 can be easily cleaned. In order to clean the inside of the container body 2, it is possible to spray compressed air to the inside of the container body 2 to blow off the powder, or to wash by pouring water into the container body 2 removed from the engine unit 17. is there.

  Furthermore, since the bone crushing apparatus 1 of the present invention crushes the bone 7 for each deceased person, the crushed material such as the remains can be pulverized without being mixed with the crushed material such as the remains of others.

  Moreover, it is also possible to form a window by providing a transparent member such as an acrylic resin in a part of the housing 5, and the pulverization state inside the closed container 6 can be confirmed visually. In addition, a sensor capable of detecting pulverization sound can be attached to the outer surface of the container body 2, and a change in the pulverization sound can be detected by this sensor to grasp the internal pulverization state. Furthermore, it is possible to determine whether or not the bone 7 has been crushed by providing a sensor capable of detecting the rotational speed of the rotary blade 33 and measuring the change in the rotational speed of the rotary blade 33.
