2. Description of the Related Art Recently, there has been an increasing trend to collect and sort out unused empty cans and glass bottles for reuse. As for the glass bottles, the glass bottles are temporarily stored in the hopper and the glass bottles are removed from the hopper. An apparatus has been put into practical use in which a predetermined amount is cut out and crushed into a predetermined particle size by a crusher.

[0003]

However, in the conventional crusher, there is an example in which an ammeter is attached to the operation panel as a means for monitoring the power load of the crusher. The glass bottle supply increases, foreign matter is mixed in and the crusher becomes overloaded,
Occasionally, you may not notice the overload of the crusher until a trouble occurs and the crusher stops, and the operator cannot grasp the load state of the crusher unless you monitor the ammeter at all times, which is a burden. Has become a big one.

In view of the above points, the present invention provides a glass bottle crushing plant capable of automatically operating in an appropriate load state without the operator having to constantly monitor an ammeter when operating the glass bottle crusher. The purpose is to do.

[0005]

In order to achieve the above object, the present invention provides a crusher in which a glass bottle stored in a hopper is cut out by a feeder and crushed by a predetermined amount, and the crusher is based on the rated load capacity value of the crusher. The proper load capacity value is set in advance in the supply control device, the power load of the crusher is detected during operation of the crusher, and when the detected power load is larger than the appropriate load capacity value, the cutting amount of the glass bottle by the cutting feeder And the amount of cutting out of the glass bottle is controlled to increase when the power load is smaller than the appropriate load capacity value.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION According to the glass bottle crushing plant of the present invention, the glass bottle stored in the hopper is cut out by the cutting feeder and supplied to the crusher, and when crushing to a desired particle size, the power load of the crusher is reduced. If the power load is detected and the power load is larger than the appropriate load capacity value preset based on the rated load capacity value of the crusher, the cutting amount of the glass bottle is reduced.If it is smaller than the appropriate load capacity value, the cutting amount of the glass bottle is decreased. Adjust automatically to increase.
In this way, the load of the crusher is automatically kept within an appropriate range, so that damage to the crusher due to foreign matter mixed in is avoided and efficient crushing can be performed.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the structure of a glass bottle crushing plant. Reference numeral 1 is a hopper for storing recovered glass bottles, and a cutting feeder 2 of a vibrating feeder system is arranged below the hopper. In the cutting feeder 2 of the vibration feeder system, the cutting speed is adjusted by increasing or decreasing the vibration frequency by changing the rotation speed of the motor 3. Further, here, the vibration feeder is described as an example of the cutting feeder, but various other feeders such as a conveyor type may be used as the cutting feeder, and it may be appropriately selected according to the capability of the apparatus.

Reference numeral 4 in the figure is a crusher for crushing crowbin. The crusher 4 has a rotating shaft 5 to which a large number of arms 6 are radially fixed, a hammer 7 for crushing is attached to the tip end thereof, and a motor 8 is used. A rotating shaft is often used, but other crushing machines such as rotating chains and other crushing means are also conceivable. Depending on the capacity of the crushing machine, various crushing machines can be used. A crushing means may be adopted as appropriate.

Reference numeral 9 in the figure denotes a vibrating screen for sieving the glass pieces crushed by the crusher 4 according to particle size,
The vibrating screen 9 is made by layering a screen mesh with smaller openings toward the lower side to form a layer, and vibrating it back and forth at a predetermined angle to send the crushed glass pieces forward so as to screen it to a desired particle size. I have to.

Below the vibrating screen 9, a storage bin 10 having a compartment formed by partitioning the inside into a plurality of compartments is arranged. Glass pieces sieved by the vibrating screen 9 are stored in the compartment according to particle size. I am trying. Further, a glass piece that is oversized by the sieve net overflows from the sieve net and is returned to the crusher 4 to be crushed again.

Reference numeral 11 in the figure is a supply amount control device for controlling the supply amount of the glass bottle, which takes in the power load amount detected by the power load detector 12 attached to the motor 8 of the crusher 4 and supplies the power load. A rotation speed control signal for instructing the rotation speed is sent to the motor 3 of the cutting feeder 2 according to the amount.

Next, the operating procedure of the glass bottle crushing plant will be described with reference to the flowchart of FIG.

First, as an initial setting, the standard rotation speed of the motor 3 for driving the cutting feeder 2 of the hopper 1 is input and set to the supply amount control device 11 (S1). Next, the proper load capacity value of the motor 8 of the crusher 4 is input and set based on the rated load capacity value as a value equal to or slightly lower than the value (S2). When the input is completed, it is determined whether or not the input is to be ended (S3). If the input is to be ended, the process proceeds to END to end. If the input value is to be corrected or the like, the process returns to S1 to return. input.

Next, the crusher 4 and the vibrating screen 9 are driven to start the operation of the crushing plant (S4). Then, the driving of the motor 3 of the cutting feeder 2 is started at the standard rotation speed which is preset and set (S5). The glass bottle in the hopper 1 is supplied to the crusher 4 by driving the cutting feeder 2 (S
6) When the crushing of the glass bottle is started, the power load detector 12 causes the motor 8 of the crusher 4 to have a current value (or a power value).
Is detected and sent to the supply amount control device 11. (S7).
The supply amount control device 11 compares the detected current value (or electric power value) of the crusher 4 with an appropriate load capacity value which is preset and set (S8), and the detected current value (or electric power value) is lower than the appropriate load capacity value. It is judged whether or not it is large (S9), and if it is large, an instruction is issued to decrease the rotation speed of the motor 3 of the cutting feeder 2 (S10). If it is small, the rotation speed of the motor 3 of the cutting feeder 2 is increased. To instruct (S1
1).

At this time, if the appropriate load capacity value is further provided with an upper limit value and a lower limit value, and an operating range between them is set as a permissible value, the rotational speed of the motor 3 for driving the cutting feeder 2 can be smoothly controlled, which is practically used. Target.

Subsequently, it is judged whether or not the operation of the crushing plant is to be ended (S12), and when the operation is to be continued, S7.
Returning to step S7 to S11, the power load of the crusher 4 is properly maintained by repeating each step. When ending the operation, the process proceeds to END, the driving of each device is stopped, and the operation is ended.
