DETAILED DESCRIPTION OF THE INVENTION

[0001]

This invention relates to a reinforced plastic,
The present invention relates to a crusher for a laminate and a phenolic resin molded product.

[0002]

2. Description of the Related Art Conventionally, as a method of reusing industrial waste such as reinforced plastics, laminates and phenolic resin molded products, it has been known to grind the powder into a powder form with a grinder and use it as a filler instead of calcium carbonate. Many.

In this case, as a method for producing fine powder,
Due to the longevity of the crusher blade, a cylindrical grinding tool type crusher with excellent wear resistance in which diamond and the like are embedded in the cylinder surface is used. Actually, fine powder is manufactured by manually inputting into an apparatus as shown in JP-A-63-39648.

[0004] For example, as shown in FIG. 17, in a state where the upper portion of a crushed material (object to be crushed) 2 stored on a support plate 3 is pressed by a pressing roller 4, a cylindrical grinding tool type crusher is pushed by a pusher 5. The crushed material 2 is pressed against the cylindrical surface 1-2 to be crushed.

[0005]

However, the method disclosed in Japanese Patent Application Laid-Open No. 63-39648 has a drawback that the crushing ability is lacking because the crushing cannot be performed while the crushed material is supplied to the crushing machine. was there.

As a means for supplying the crushed material, pneumatic transportation or a method of supplying the crushed material to the crusher by a conveyor or a robot instead of manual work may be considered. However, in the pneumatic transportation, since the crushed material is heavy, When transporting is difficult, and when using a conveyor, it cannot be pressed against the crusher during falling and the crushed material cannot be uniformly dropped.Therefore, crush in a part of the width of the crusher. However, there was a problem that the grinding ability was greatly reduced.

[0007] Further, when a robot is used, if the size and shape of the crushed material are not uniform, handling becomes difficult, and there is a problem that mass production equipment is unsuitable in terms of cost and performance.

Therefore, in actuality, means for supplying the crushed material to the crusher must be manually performed.

Generally, a method of crushing before crushing is employed, but with a crusher, 100 to 300 mm × 100 to 3 mm.
Because it crushes big like 00mm, the ability comes out easily,
Since the pulverizer requires fine powder of 1 to 100 μm, the production capacity is low, and when the pulverizer and the pulverizer are connected in a one-to-one relationship, the capacity of the entire apparatus cannot often be exhibited. When trying to connect 2 to 4 crushers to the table, the connection was difficult.

The present invention has been made in view of such circumstances, and provides a pulverizing apparatus capable of improving the pulverizing ability and automatically performing an integrated operation from coarse pulverization to pulverization. It is an object.

[0011]

In order to achieve the above object, a crushing apparatus according to the present invention comprises a crusher for crushing a reinforced plastic, a laminated plate and a phenolic resin molded product, and a crusher for crushing the phenolic resin. The crushed material was weighed to a predetermined amount by a quantitative control device, and a container for accommodating the crushed material, a leveling device for leveling the crushed material in the container, and a crusher and a cylindrical grinding tool type crusher were filled with the crushed material. A transport device equipped with a guide for transporting the container, and the cylindrical surface of the cylindrical grinding tool type crusher, in which the crushed material in the container is covered with a cover covering the upper opening of the container transported in front of the cylindrical grinding tool type crusher. And a pusher that performs pressing and crushing.

As the above-mentioned conveying device, a series of devices including one or more pulverizers is connected by using an asynchronous intermittent feeding one-way driving conveyor which can be moved and supplied at any time required, or one crusher is provided. In addition, two intermittent mills placed on both sides of the intermittent feeder are connected by a synchronous intermittent feed alternate-direction drive conveyor, or a synchronous intermittent feeder having a large number of partition plates perpendicular to the traveling direction instead of the transport device and the container. It is also possible to use a directional drive conveyor, synchronous intermittent alternate feeder with rack and pinion or synchronous intermittent alternate rotary feeder, to feed the crushed material directly to the crusher side by sandwiching it between conveyors, or from the container without using a transport device. The crushed material may be directly supplied to the crusher side.

Further, in addition to the container having the above configuration, the container may be replaced with a container and a guide, and a side wall in a direction perpendicular to the traveling direction of the transfer device is fixed and both side surfaces parallel to the traveling direction are open. A cylindrical container may be used.

It is important that the cutter axis of the crusher and the cylindrical surface of the crusher of the cylindrical grinding tool type are installed so that they are parallel to each other.

[0015]

As is apparent from the above constitution, if the crushing device according to the present invention is used, reinforced plastic, phenol-epoxy resin crushed by a crusher such as a shredder or a shear in a container placed on a transfer device. Drop the crushed product of the laminated plate or phenolic resin molded product, and when it reaches a predetermined amount, shut off devices such as dampers etc. by the completion signal of quantitative control device such as weight control by weigher, time control by timer, volume control by position sensor etc. Close and then open the container 2
While the surface is closed by the fixed guide, intermittent feeding is performed to the leveling device by the transfer device.

Further, the crushed material in the container is leveled evenly and horizontally by a leveling device such as a vibrating device, and then is intermittently fed by a transfer device to a position in front of a cylindrical grinding tool type pulverizer. The crushed material is pulverized by being covered with a cover and pressing the crushed material in the container against the cylindrical surface of the cylindrical grinding tool crusher with a pusher.

[0036]

As described above, the pulverizing apparatus according to the present invention has the following special functions and effects.

According to the present invention, when the crushed material is put into the crusher, the crushed material is automatically supplied to the crusher thereafter, and the productivity is improved as compared with the conventional manual crushed material supply. .

Further, it is moved and moved by the intermittent feeding conveying device.
Stopping is repeated, but it is possible to perform operations such as dropping, leveling, crushing etc. during the stoppage, and filling the container with crushed material in a space different from the crusher, eliminating the waiting time of the crusher, The operating rate increases and the productivity improves.

In addition, since a fixed amount is uniformly supplied by the equalizing device, the material is always pulverized in an ideal state, thereby improving the productivity. There is no need to do this, and labor can be saved and productivity can be improved.

In addition, since a two-sided open container is used, the supply to the pulverizer becomes easy, and since a cylindrical grinding tool type pulverizer is used, the life of the blade is long, and unlike a shear type pulverizer,
This eliminates the need for maintenance to maintain a constant blade spacing and is ideal for grinding highly abrasion-resistant materials such as reinforced plastics, phenolic-epoxy laminates, and phenolic resin molded products.

In addition, instead of pellets, coarsely crushed
Fine powder of about 0 μm can be obtained, and the process is simplified.

As described above, according to the present invention, it is possible to automatically and consistently perform processing from crushing to pulverization, and it is possible to efficiently exert the performance of a crusher, thereby significantly improving productivity. This has the effect.

Next, the operation and effect unique to each embodiment of the present invention will be described.

First, when an asynchronous intermittent one-way driving conveyor is used for the transport device, even if there is a variation in the time of each process, if a waiting process is set during that time, when it is necessary,
Since it can always be sent to each process independently, the operating rate is greatly improved.

Further, since one or more crushers, for example, several crushers can be installed and connected to one line for one crusher, the crusher can be reliably supplied to the crusher. Such as Hundley FRP, which has a large amount of resin components and is particularly suitable for a material having a low crushing ability, and a crusher is relatively large, such as 100 to 300 mm x 100 to 300 mm, and thus tends to have a high production capacity. In a crusher, it is necessary to make fine powder of 1 to 100 μm,
Although the production capacity is low, two to four crushers can be connected to one crusher as in the present invention.
Overall equipment capacity is improved and investment costs are reduced.

When a synchronous intermittent feeding alternate direction driving conveyor is used as the transporting device, one of the two crushers is always inactive, but the equipment cost is reduced.

When a synchronous intermittent one-way drive conveyor is used as the transfer device, the correspondence between the crusher and the crusher is one.
Although there is little advantage in the case of using a one-to-one asynchronous intermittent feed one-way drive conveyor, there is an advantage that the equipment cost can be reduced.

If a container having a structure in which two side walls perpendicular to the traveling direction are fixed and the remaining two side walls are slidable in the vertical direction is used, it is not necessary to install guides on both sides of the transfer device, and the cost is reduced. Becomes

When a shredder is used for the crusher, the crusher has the ability to crush large amounts of crushed material of 100 to 300 mm × 100 to 300 mm as compared with a shear or the like, and is excellent as a mass production facility.

It should be noted that this is one of a series of facilities described above.
The effect can be particularly exhibited when used as one.

When a scale is used for the quantitative control device, the ideal amount of the crushed material can always be constantly supplied to the crusher side, so that the crusher can exert its capacity without any limitation. In addition to improving the capacity, it can also contribute to extending the life of the blade of the crusher.

It is needless to say that the weigher is weighed by weight, so that quantitative control can be performed with high accuracy.

On the other hand, when a timer is used in the quantitative control device, the accuracy of the quantitative control is slightly inferior, but the device can be manufactured at a low cost and, like the weighing method, installed in the same process as the crusher together with the leveling device. , So that more crushed material can be stored in the container, the capacity of the crusher,
This leads to longer tool life.

On the other hand, the case where the position sensor is used in the quantitative control device is the same as the case of the timer.

Since the width of the crushed material varies from 100 to 500 mm, the width falling into the container varies from 150 to 550 mm. When using a vibrating device for the leveling device, the crushed material in the container is leveled evenly over the entire surface, so that it hits the cylindrical surface of the crusher uniformly and over the entire surface, improving the crushing ability. In addition, since local heating due to local contact does not occur, the life of the blade on the cylindrical surface of the crusher can be extended.

Next, a leveling device using a mechanical stirrer eliminates the need for a container for accommodating crushed material, and is indispensable when a synchronous intermittent feeding one-way drive conveyor is used. Cannot be used due to its structure.

When a vibration having a frequency of 1 to 100 Hz and an amplitude of 0.03 to 5 mm is applied to the container in a horizontal or vertical direction by a vibrating device, the crushed material in the container can be evenly leveled in the horizontal direction. did it. Thereby, the effect as described above can be exerted.

When the blade axis of the crusher and the cylindrical surface of the cylindrical grinding tool type crusher are installed in parallel, the width of the crusher and the width of the crusher are more easily approximated than in the case where they are respectively installed in orthogonal directions. Therefore, since the container width is also approximated, the crushed material falls cleanly from the crusher to the container, and the pressing to the crusher by the pusher tends to be uniform in the width direction, which leads to an improvement in crushing ability and a longer blade life.

When the blade axis of the crusher and the cylindrical surface of the cylindrical grinding tool type crusher are installed in a direction orthogonal to each other, the depth of the container becomes unnecessarily large due to the width of the crusher. A large amount of crushed material accumulates in the direction, the pressurization of the crusher by the pusher tends to be insufficient, and the crushing capacity tends to decrease, but when installed in parallel, the depth of the container becomes 3 based on the width of the crusher
These drawbacks can be eliminated by setting the dimensions to about 100 to 450 mm.

In the case where the materials are sent to the left and right containers by the weighing conveyor and then alternately supplied to the central crusher by the rack and pinion, the installation area is small.

Further, the crushed material put into the cylinder from the crusher is supplied alternately to the left and right by using a rack and pinion, and the installation area is also small when pressing and crushing with a pusher. Space efficiency is improved.

Further, in any of the eighth, ninth and tenth embodiments, since there is no transfer device and the crusher and the crusher are directly connected, the installation area can be reduced, and the space can be saved as described above. Has the effect of greatly contributing to

Table 1 shows the effects of the main embodiment, but it has been found that other embodiments and other reinforced plastics, phenol / epoxy laminates, and phenol resin molded products have the same effect.
