Abstract

PROBLEM TO BE SOLVED: To reduce weight by miniaturization, to make transportation easy and to simplify an assembly operation by making a crushing part having rotary blades, a driving device, and a roller case separable by a housing part in which a container is placed and an attachment/detachment apparatus. SOLUTION: In a crushing part 2, a rotary blade part, a driving device, and a roller case are provided. In order to disassemble a board crushing apparatus to be divided into the crushing part 2 and a housing part 3, the door of the housing part 3 is opened, and when the lock lifting handle of a crushing part lock mechanism 41 is pulled against the repulsion force of a spring, a lock pin is pulled out from a receiving hole. When the crushing part 2 is slid from the position of an upper base fixed guide channel 14B to the position of an upper base insertion guide channel 14C, the parts 2, 3 can be disassembled. In this way, weight is reduced by miniaturization, and transportation is made easy. In order to open the door to be separated, since a door detection switch detects it, the crushing part 2 is not actuated even when operated with a power source turned on, and work can be done safely.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of crushing an object to be crushed, such as a gypsum board, to reduce the volume of the object to be crushed and to prevent noise and dust at the time of crushing from being scattered around. The present invention relates to a board crushing device that is easy to use.

[0002]

2. Description of the Related Art In recent years, there has been an increasing social demand for environmental protection and recycling, and gypsum boards, which are construction waste materials, are not discarded as they are but are subjected to post-treatment, which may affect the environment. Gypsum board deposits (such as paper and pulp) are incinerated, and useful gypsum is expected to be recycled. Similarly, besides plasterboard,
There is also a need in the world for waste materials such as tiles and tiles to be crushed at building sites to facilitate crushing and transportation, and to be recyclable at the same time.

[0003] As a conventional crushing apparatus for such recycling, there is Japanese Patent Application Laid-Open No. Hei 6-277537. A pair of pinch rollers and a pair of cutter rollers are provided, and the cutter roller rotates at a higher speed than the pinch rollers. The gypsum board is eaten with a pinch roller and crushed finely. However, the pinching and pinching operations of the pair of pinch rollers require the rotation of the rollers and the swinging (revolution) of the arm, which complicates the driving mechanism and causes a failure due to the complexity. It was easy. In addition, when a difference in biasing force is generated between the pinch rollers, the feeding direction of the gypsum board that has been eaten fluctuates, and when crushing, it is likely to hit one of the cutter rollers and hit easily. . The longer the pulverizer is used for a longer period, the more the biasing force tends to appear. The conventional crushing apparatus needs to be transported to the site, installed and worked on the site, but the size is considerably large and the weight is heavy, which makes it difficult to transport.

As a conventional crushing apparatus, there is Japanese Patent Application Laid-Open No. Hei 8-1023 proposed by one of the present inventors. This conventional technique is intended for cutting general paper or the like, and is provided with a pipe-shaped shutter. However, since it does not have a function of self-rotation by driving or the like, it does not perform a process for preventing the thickness of a tangible material to be crushed such as a gypsum board from being overloaded.

[0005]

As described above, in the conventional crushing apparatus (Japanese Patent Laid-Open No. Hei 6-277537),
The gypsum board is eaten and crushed by a pair of pinch rollers, but the feeding direction of the gypsum board becomes unstable and fluctuates. This instability in the direction of feeding increases the impact noise during crushing and shortens the life of the device. Also, to drive the pinch roller,
In addition to the driving source for driving the cutter roller, another driving source was required, and it was necessary to control the speed of the driving source. This increases the number of vibration sources, increases noise and shortens the life,
Costs are also high. In addition, this type of crushing equipment has the essential problem of having to carry the equipment to the construction site to process the gypsum board, and for this purpose downsizing is desired. It becomes large. In addition, a gap is formed between the guide plate and the pair of pinch rollers to allow the arm to swing, and dust inside leaks through the gap. Sound was leaked for the same reason.

Another conventional crusher (Japanese Patent Laid-Open No. 8-1)
No. 023), since a gypsum board or the like is a thick material to be crushed, there is also a problem that the material to be crushed is clogged during transfer and the crushing function is stopped. Unless the means for transferring the object to be crushed is provided in the crushing device, it is difficult to reduce the size and weight. Since there are a pair of pipe-shaped shutters, problems such as dust and noise are basically the same as those of the crushing device described above.

Further, since these crushing devices are used only on site, a person who is unfamiliar with the handling of the device first obtains operating know-how so as not to block the crushed material. It was something I needed to get.

The present invention has been made in view of such problems, and does not generate noise during crushing and does not leak to the outside. To provide a recyclable board crushing device.

[0009]

In order to solve the above-mentioned problems, a board crushing apparatus according to the present invention comprises: an inlet guide provided at a board inlet for guiding the board; and an upper surface of the inlet guide. And a roller case provided with an opening surface facing the upper surface of the loading guide, and housed in the roller case.

Press. The pushing causes the regulating roller 4 to ride on the upper surface of the board 10. Thereafter, when the leading end of the board 10 reaches the rotary blades 6A and 6B and is eaten by both, the board 10 is retracted by this, and the tension state continues until the end of the board 10 passes through the regulating roller 4. After the board 10 has passed, the regulating roller 4 again comes into pressure contact with the surface of the inlet guide 5 by its own weight.

As described above, the regulating roller 4 has its own weight and the board 1.
0 seals and shuts off the inside and outside of the board crusher,
When the board 10 having a small width is inserted, the following problem occurs. That is, as shown in FIG. 4 (E), it is also conceivable to insert the board 10 one-sidedly into one of the insertion port guides 5, and in this case, only one side of the regulating roller 4 is lifted, resulting in an inclined state. . At this time, if a single inlet switch 11 is provided at the center of the rear part of the roller case 12, the regulating roller 4 is inclined and does not come into contact with the inlet switch 11, so that the switch is not turned on. In the present embodiment, in order to prevent such inconveniences, one and two convenient opening switches 11 are respectively provided near both ends in the longitudinal direction of the rear surface of the inner surface of the roller case 12, and the driving device is logically ORed.

As shown in (D), both of the inlet switches 11 are turned on, and the logical sum of both is also turned on, so that the driving device 7 starts operating without any problem. Thereafter, when the board 10 is retracted and the board 10 is no longer present at the regulating roller 4, the state again becomes as shown in FIGS. 4A and 4D, and both of the inlet switches 11 are turned off. In this embodiment, when the rotary blades 6A and 6B are stopped, two input port switches 1 are used.
By taking the logical product of 1 and off, the rotation of the driving device 7 is stopped only when both are off. At this time, the operation is stopped after a predetermined time has elapsed by a timer (not shown). This is for crushing without leaving the board 10. FIG.
The operation is stopped only when the state of (C) is reached, so safety is ensured. Even if dust is floating in the crushing section 2 after crushing, this does not leak to the outside, and crushing does not occur. Even when odor is generated due to the odor, the odor does not leak to the outside.

Next, a description will be given of a device for attaching and detaching the crushing unit 2 and the storage unit 3, which is a feature of the first embodiment. Reference numeral 40 denotes a crushing unit base mounted on the base 14 provided on the upper surface of the storage unit 3 and forms a bottom surface of the crushing unit 2; 41, a crushing unit lock mechanism for attaching and detaching the crushing unit 2 and the storage unit 3; A support fitting, 41B is a pin pressing spring, 41C is a lock pin as a guide, and 41D is a lock release handle. In addition, the upper base fixing guide groove 14B and the upper base insertion guide groove 14B are attached and detached between the crushing unit 2 and the storage unit 3.
C, the fitting member 37 (guide) is involved.

The lock pin 41C has a pin pressing spring 41B.
A spring receiving portion receiving the urging force is formed. The pin pressing spring 41B includes a spring support 41A and a lock pin 41C.
, And presses the lock pin 41C against the crushing section 3 side. The base 14 and the crushing part base 40 respectively have receiving holes through which the crushing part 2 and the storage part 3 are exactly overlapped when the crushing part 2 and the storage part 3 are placed at the predetermined mounting positions, and the lock pins 41C are inserted through both bases to prevent sliding. Is provided. Lock pin 41C
The spring receiving portion serves as a stopper for keeping the insertion length of the lock pin 41C constant. When the crushing unit 2 and the storage unit 3 come to the correct positions, they are automatically locked by these attaching / detaching devices. Conversely, when releasing the lock pin 41C, the lock release handle 41D may be pulled to pull out the lock pin 41C.

Since the fitting member 37 is formed downward in the crushing portion base 40, if the fitting member 37 is inserted into the upper base insertion guide groove and slid as it is, the fitting member 3 is formed.
7 moves forward until it contacts the upper base stopper 14A,
At the contact position, it fits exactly into the upper base fixing guide groove. At this time, the crushing unit 2 and the storage unit 3 are connected to the stopper 14A.
And a predetermined mounting position is reached, and the lock pins 4 formed on the base 14 and the crushing portion base 40 are formed.
The receiving holes of 1C are in an overlapping state. In this state, the lock pin 41C enters the hole by the urging force of the pin pressing spring 41B, and the crushing unit 2 and the storage unit 3 are locked.
At the same time, the connector socket (not shown) of the crushing unit 2 is attached to the connector housing (not shown) of the storage unit 3, so that electrical continuity between them can be achieved.

Conversely, the board crusher is disassembled and the crusher 2
In order to divide the lock pin 41C into the storage section 3 and open the door 25 of the storage section 3 and pull the lock release handle 41D against the elastic force of the spring, the lock pin 41C is pulled out from the receiving hole. As it is, the crushing part 2 is fixed to the upper base fixing guide groove 14B.
Is slid from the position to the position of the upper base insertion guide groove 14C, the crushing part 2 and the storage part 3 can be disassembled. Since the opening and closing door 25 is opened and separated, the opening and closing door detection switch 26 detects this, so that the crushing unit 2 does not operate even if the operation is performed while the power is on, and the operation can be performed safely.

The fitting member 37 inserted into the upper base insertion guide groove 14C and the upper base fixing guide groove 14B is used as a lock pin 41C, and a receiving hole for the lock pin 41C is provided in the upper base fixing guide groove 14B. May be. In this case, the configuration for the guide and the configuration for the lock can be shared, and the number of parts can be reduced.

As described above, the board crushing apparatus according to the first embodiment can be disassembled into the crushing section 2 and the storage section 3 by the attachment / detachment apparatus, and is small in size, light in weight and easy to carry. The assembling operation is also easy, and an assembler can easily assemble on site.

Next, the operation when operating the board crushing apparatus of the first embodiment will be described. The user turns on the power switch 27 first. Next, look at the operation unit 28,
The storage container 20 is set by the storage container detection switch 21, the opening and closing door 25 is closed by the opening and closing door detection switch 26, and there is still enough room to store crushed materials in the storage 20 by the full detection switch 23. Check that there is. When these conditions are satisfied, when the board 10 such as a gypsum board is inserted into the slot between the roller case 12 on the slot guide 5, the regulating roller 4 pressed against the surface of the slot guide 5 by its own weight is used. It is lifted into the roller case 12 by the insertion force. Control roller 4 at the same time
Is rotated by frictional force and can be inserted smoothly. The pushing operation of the regulation roller 4 turns on the logical sum of the input switch 11 and the driving device 7 starts rotating. The driving sprocket 19B and the driven sprocket 19C connected thereto rotate, and the rotary blades 6A and 6B mesh with each other and start rotating. When the tip of the board 10 inserted between the rotary blades 6A and 6B is reached, the two bite and pull in the board 10 to perform pulverization. Since the logical sum of the input port switch 11 is calculated, the rotary blades 6A and 6B can be reliably connected regardless of the form of the board 10 or the case where the board 10 is inserted in one side. Can be turned on. Further, the board 10 is moved along the input port guide 5 surface.
Is inserted, the insertion direction is not unstable as in the case of inserting between a pair of pinch rollers of the related art,
Since only the board 10 up to the height of the insertion port between the insertion port guide 5 and the roller case 12 can be inserted, the drive device 7 cannot be predicted and does not become overloaded. If an overload occurs, the board crushing apparatus of the first embodiment detects that the rotation speed of the rotary blades 6A and 6B is extremely reduced or stopped by the rotation detection sensor 29 of the operation unit 28. Then, the control unit 31 reverses the driving device 7 to release the locked state. At this time, an overload is also displayed on the operation unit 28.

As described above, the board crushing apparatus according to the first embodiment can be disassembled into the crushing section 2 and the storage section 3 by the attachment / detachment apparatus, and is small in size, light in weight and easy to carry. The assembling operation is also easy, and an assembler can easily assemble on site. In addition, when the board 1 is inserted, the input opening opens only a minimum space due to the pressing action of the regulating roller 4 when the board 1 is inserted.
No crushing noise or dust is leaked to the outside, and no odor inside is leaked. Further, when the vehicle is locked and becomes overloaded, it is reversed and the lock is released to protect the drive device 7, which is safe. Since the overload is prevented and the sealing is performed only by the regulating roller 4 and the introduction port guide 5, the board crushing device can be reduced in size and weight. Further, when the board 10 has a long length in the longitudinal direction, the board 10 itself is used as the drawing means without specially providing a drawing device, so that the structure can be simplified.

When the fullness detection switch 23 detects fullness, a display indicating fullness is lit on the operation unit 28, and the control unit 31 temporarily stops the rotation of the driving device 7, so that the user opens the door 25. The storage container 20 may be taken out and replaced with a new storage container 20. When this replacement is completed, the storage container detection sensor 21 is turned on, the open / closed door detection switch 26 is turned off, and the fullness detection switch 23 is turned off, and if the temporary stop release switch (not shown) is pressed, the crushing is performed again. Since the operation is started, the automatic operation is performed while detecting the full state of the storage container 20, so that the operation of the crushed material is not mistaken and the operation is easy.

For this reason, the same members as those in the first embodiment except for the parts showing the features of the second embodiment are denoted by the same reference numerals, and the description thereof will be omitted from the first embodiment.

A feature of the board crusher of the second embodiment is that a transfer path guide 32 and a transfer roller 33 are provided instead of the input port guide 5 of the first embodiment. The transport path guide 32 has an opening for the transport roller at a position where the regulating roller 4 is exposed from the opening surface of the roller case 12, and the upper end of the roller surface of the transport roller 33 in the aperture for the transport roller is the transport path guide 32. Is provided at the position of the upper surface. Therefore, in the normal state in which the operation is stopped, the regulating roller 4 is pressed against the transport roller 33 by its own weight to seal the inside and outside of the board crushing device. 34 is a driven pulley, 35 is a driving pulley, and 36 is a conduction belt for transmitting power between the driving pulley 35 and the driven pulley 34. The attachment / detachment device for the crushing unit 2 and the storage unit 3 is the same as that of the first embodiment, and the base stopper 14A, the upper base fixing guide groove 14B, the upper base insertion guide groove 14C, and the fitting member 3
7, crushing portion base 40, crushing portion lock mechanism 41, spring support fitting 41A, pin pressing spring 41B, lock pin 41
C, a lock release handle 41D and the like. The disassembling and assembling operations using these are the same as those described in the first embodiment, and therefore will not be described.

The drive pulley 35 is connected to the rotary shaft 17 of the rotary blade 6A.
Is driven by gear transmission. This drive pulley 3
Reference numeral 5 further transmits power to the driven pulley 34 by a conduction belt 36. The driven pulley 34 drives the transport roller 32 attached to the rotation shaft. Therefore, when the rotary blades 6A and 6B are driven, the transport roller 32 is also driven. As described above, the transport rollers 33 support the transport of the board 10 from the lower surface side of the transport path guide 32.

An operation when using the board crushing apparatus according to the second embodiment will be described. The user turns on the power switch 27 first. Next, looking at the operation unit 28, the storage container 20 is set by the storage container detection switch 21, and the door 2 is detected by the door detection switch 26.

When these are OK, when the board 10 is inserted into the slot between the roller case 12 on the slot guide 5 as in the first embodiment, the regulating roller 4 pressed against the transport roller 33 by its own weight is inserted. It is lifted into the roller case 12 by force. At the same time, the regulating roller 4 starts to rotate by frictional force. The pushing operation of the regulation roller 4 turns on the logical sum of the input switch 11 and the driving device 7 starts rotating. Along with this, the drive side sprocket 19B,
The driven sprocket 19A and the rotary blades 6A, 6B mesh and start rotating. Since the paper is forcibly fed by the transport roller 33, even if the board 10 is small, the rotary blades 6A, 6
B can be crushed. When the board 10 is inserted, the transport roller 33 is rotated by friction by the force of inserting the board 10, and when the regulating roller 4 is pushed up, the rotating blades 6A and 6B are started to be driven. Then, since the automatic conveyance is started by the regulating roller 4 driven by the rotation, the user finely adjusts the insertion force and the insertion direction and pushes up, so that an overload is not caused as compared with the conveyance by the conveyance roller 33 from the beginning.

As described above, in the board crushing apparatus according to the second embodiment, when the board 10 is inserted, the inlet is opened only with a minimum gap, so that during the crushing, after the crushing, the crushing sound and dust are also generated outside. It does not leak and no internal odor leaks out. In addition, a load is likely to be imposed on the drive device immediately after the start of operation, but this can be avoided by manual insertion, so that overload can be prevented. Further, reliable transport can be expected by the transport roller 33.
