2. Description of the Related Art Foamed polystyrene (so-called expanded polystyrene: EPS, hereinafter referred to as expanded polystyrene) is used for packaging of home electric appliances and AV (audio visual) equipment.
Are used in large quantities. This type of styrofoam has features such as excellent impact buffering properties, easy processing into an arbitrary shape, and low price and good appearance. However, when incinerated as waste, Styrofoam generates high heat and shortens the life of the incinerator, and also produces severe odors and does not decompose in the soil even if discarded. In recent years, as environmental protection and the tendency to conserve resources have been increasing, its mass use has been questioned in recent years.

[0003]

Therefore, as an alternative to styrofoam, pulp molding materials produced by recycling milk packs, cardboards, newsprints and the like have begun to be partially used. However, while Styrofoam exhibits excellent shock-absorbing properties due to its own elasticity, pulp mold materials provide buffering properties by processing paper into an uneven shape, so its strength and cushioning properties There is a limit and the variation in characteristics is large. Therefore, for general packaging products, especially large products such as refrigerators, washing machines, and televisions, for the time being, styrofoam must be mainly used as a packaging material. Therefore, attempts have been made to collect and recycle the Styrofoam compact.

Conventionally, such a device for crushing polystyrene foam has a structure as shown in FIGS. 10, 11 and 12. FIG. In the crushing apparatus shown in FIG. 10, the styrofoam 1000 crushes while pressing it between the fixed wall 1001 and the rotary blade 1002.

Therefore, in order to efficiently pulverize the Styrofoam, it is necessary to provide a plurality of arms and a plurality of rotating blades for pressing the foaming roll against the rotating blades. As a result, the mechanism becomes complicated and the manufacturing cost of the apparatus is increased. In order to pulverize a large polystyrene foam, a rotary blade for coarse pulverization and a rotary blade for fine pulverization are required, and the mechanism becomes complicated and the cost increases. When a plurality of rotary blades are used for crushing, a large power is required for crushing and power consumption is increased. The need for high power required a robust structure, which was heavy and expensive to manufacture. The pulverized styrene foam is accumulated in the pulverizer due to its lightness and static electricity, and thus has a problem in discharging. Therefore, the present invention solves the above-mentioned problems, a resin object such as styrene foam can be finely and efficiently pulverized without difficulty, and a resin object capable of reliably and efficiently discharging the pulverized object to the outside of the apparatus.

The operation is controlled by a command from the control unit 100.

Next, the operation of the above-described resin object crushing apparatus will be described. For example, an operator opens the cover portion 34 shown in FIG. 1 in the direction E and puts a plurality of polystyrene foams 30 into the container 12. Then, after the lid 34 is closed, the motor 66 and the motor 68 operate. Then, the air supply device 230 and the suction device 200 operate.

When the motor 68 shown in FIG. 4 is operated, the moving body 64 shown in FIG. 3 starts moving in the X1 direction due to the engagement between the rack 88 and the pinion gear 86. FIG.
When the motor 66 operates, the pulleys 80 and 82 shown in FIG. 2 rotate, and the rotary shaft 78 and the rotary blade 62 continuously rotate in the R1 direction. Thereby, the moving body 64 shown in FIG.
As shown in FIG. 1, the rotating blade 62 rotates in the R1 direction while moving in the X1 direction, and the Styrofoam 30 positioned between the rotating blade 62 and the inner surface of the lower portion 38 of the container 12 is roughly pulverized by the rotating blade 62. Styrene foam 40 which is roughly pulverized. The rotating blade 62 linearly moves toward the inner surface 39 of the lower portion 38 of the container 12 while rotating. As a result, the Styrofoam 30 is sandwiched and pressed between the rotating blade 62 and the inner surface 39 that move straight, and is pulverized while being retracted to form the roughly pulverized Styrofoam 40.

At this time, as shown in FIG.
1 and 7, the rack 88 shown in FIGS. 1 and 7 moves in the X2 direction against the urging force of the spring 134.
4 relative to 4. That is, the spring 134 is compressed, the first propulsion force detecting element 114 is turned on by the movement of the receiving member 130, and the signal S2 is sent to the control unit 100 in FIG. The control unit 100 temporarily stops the operation of the motor 68. As a result, the Styrofoam 30 sandwiched between the rotary blade 62 and the inner surface 39 moves the rotary blade 62 at which the linear movement stops.
Is further coarsely ground. When the styrofoam 30 is roughly pulverized and the propulsive force becomes equal to or less than a predetermined value, the control unit 100 operates the motor 68 again to send the rotary blade 62 in the X1 direction, and starts the pulverization of the styrofoam 30 by the rotary blade 62. At this time, when a large load is applied to the rotary blade 62 at the time of pulverization, the rotary load detecting element 140 outputs a signal S1 to the control unit 100 shown in FIG. Thus, the control unit 100 stops the motor 66 or performs a reverse operation to rotate the rotary blade 62 in the direction of R2. When the load applied to the rotary blade 62 becomes appropriate, the rotary blade 62 rotates forward in the R1 direction again.

The rotary blade 62 that has reached the vicinity of the inner surface 39 of the container 12 shown in FIG. 1 is reversed from the rotation in the direction R1 to the direction R2, and the control unit 100 rotates the motor 68 in the reverse direction to move. From the linear movement in the X1 direction, the body 64
Move on to linear movement 2. When the rotary blade 62 approaches the vicinity of the inner surface 39, its rotation is detected by a sensor (not shown) as R1.
The motor 64 is rotated in the direction X1 from the direction X1 by a sensor (not shown).
Reverse in the direction of 2. At this time, the styrene foam 40 coarsely crushed is located between the rotary blade 62 and the inner surface 39, and the styrene foam 40 coarsely crushed positioned between the rotary blade 62 and the inner surface 39 is R2
Is wound and sent to the fixed blade 22 side by the rotation in the direction of. Moreover, as shown in FIG. 6, since the air supply device 230 supplies compressed air from the air intake port 38A into the lower part 38 of the container 12, the foamed polystyrene 40 roughly pulverized by the compressed air smoothly moves toward the fixed blade 22 side. Gathered in.

When the moving body 64 moves in the direction X2 and the rotary blade 62 rotates in the direction R2, the styrene foam 40, which has already been roughly pulverized, is sandwiched between the rotary blade 62 and the fixed blade 22, as shown in FIG. Meanwhile, the styrene foam 40 which has been roughly pulverized becomes the styrene foam 50 which has been further finely pulverized as shown in FIG. The finely crushed styrene foam 50 is forcibly sent to the storage unit 210 side by the suction device 200. Therefore, even if the finely crushed styrofoam 50 is light and generates static electricity, the finely crushed styrofoam 50 can be reliably and smoothly fed into the storage section 210 by the suction operation of the suction device 200.

The styrene foam 50 finely ground in this way can be reliably and efficiently arranged on the storage section 210 side by air conveyance. When the rotary blade 62 shown in FIG. 1 approaches the vicinity of the fixed blade 22, the rotary blade 62 reversely rotates from the direction of R2 to the direction of R1 according to a signal of a sensor (not shown), and the motor 68 also reversely rotates. The body 64 again linearly moves in the X1 direction opposite to the X2 direction. By repeating the above operation, the styrene foam 30 stored in the container 12 can be pulverized into the styrene foam 50 that has been finely pulverized. Container 1
When the Styrofoam 30 in 2 has run out, the control unit 100
Automatically stops the operation of the motor 68 and the motor 66.

As shown in FIG. 8, when the rotary blade 62 is rotating in the direction of R2 and the moving body 64 is linearly moving in the direction of X2, the coarsely crushed portion located between the rotary blade 62 and the fixed blade 22 is crushed. When the propulsive force of the rotary blade 62 exceeds a predetermined value due to the influence of the expanded polystyrene 40, the rack 88 moves relative to the moving body 64 in the X1 direction against the urging force of the spring 124. That is, since the spring 134 is compressed and the receiving member 120 turns on the second propulsion detecting element 116 as shown in FIG. 8, the second propulsion detecting element 116 sends the signal S3 to the control unit 100. As a result, the control unit 100
8 is temporarily stopped. Then, when the coarsely crushed styrene foam 40 is crushed and the propulsion force becomes equal to or less than a certain value, the control unit 100 operates the motor 68 so that the moving body 64 starts moving to the fixed blade 22 side again in the X2 direction. It has become.

The present invention is not limited to the above embodiment. In the above-described embodiment, the moving body 6
4 moves linearly in the X1 or X2 direction,
The method is not limited to this, and the moving body may adopt a method in which the moving body is moved by a curved movement or an infinite orbiting method.

In the embodiment of the present invention, since a plurality of single rotary blades movable on one rotary shaft are provided, a plurality of rotary blades are provided or a styrofoam for pulverizing the rotary blades is pressed. The need for an arm to be attached is eliminated, the mechanism is simplified, the strength can be reduced, and the weight can be reduced, so that the manufacturing cost can be reduced. Since the number of rotating shafts of the rotary blade is reduced, the power is reduced and the cost is reduced. The crushed styrofoam can be discharged efficiently because it uses the flow of air. By providing the propulsion detection element of the moving body and the load detection element of the rotary blade, the pulverization can be performed without difficulty and efficiently.
