The shaft 42 is connected to an output shaft 53 of a rotary actuator 51 via a coupling 49. The rotary actuator 51 is configured to be capable of driving the reversing chute 27 in reverse so as to drive the reversing chute 27 in reverse, and is attached to an actuator receiver 55 fixed to the outer surface of one bearing receiver 45a. The rotary actuator 51 is connected to a compressor 59 via an air solenoid valve 57 as shown in FIG. Accordingly, the rotary actuator 51 is switched by the air from the compressor 59 through the switching of the air solenoid valve 57.
Of the rotary actuator 5
1. The air solenoid valve 57 and the compressor 59 constitute the actuator 29 which can be driven forward and reverse to reversely drive the reverse shooter 27 in this embodiment.

The air solenoid valve 57 is switched by a command from the sequencer 31. The sequencer 31 switches the air solenoid valve 57 after a predetermined delay time upon receiving the input completion signal from the synthetic resin injection molding machine 3. It has become. Accordingly, the sequencer 31 constitutes the controller 31 for driving the actuator forward / reverse at a predetermined timing.

By the continuous operation of the synthetic resin injection molding machine 3, several (for example, four) products W are molded at a time, and are received together with the runner R in the receiving port 5 of the molded article separating apparatus 1. The product W and the runner R are supplied onto the roll 9, and the rotation of the roll 9 causes the product W to fall downward from a gap between the adjustment plate (not shown) and is received by the hopper 25 of the distributor 21 from the product outlet 23.

The product W received in the hopper 25 reaches the lower outlet 37 by the guides of the chutes 35a and 35b of the hopper 25, and is stored in the first polytener 13a from one outlet 37a as shown in FIG. It has become so. At this time, an empty second polytainer 13b is arranged below the other discharge port 37b. When the number of accommodated products of the first polytainer 13a reaches a specified number, the rotary actuator 5

7, the reversing plate 39 closes the one outlet 37a and opens the other outlet 37b. During this time, the synthetic resin injection molding machine 3 is continuously operated, and the product W is successively stored in the second polytainer 13b by switching the reversing shooter 27. When the reversing shooter 27 is switched in this manner, the lamp 17 is turned on and a buzzer sounds, whereby the operator replaces the first polytainer 13a with an empty third polytainer. By such a continuous operation, the synthetic resin injection molding machine 3 can be continuously operated even during the replacement of the polytainer, the operation rate can be remarkably increased, and the number of the polytainers to be inserted becomes accurate. Further, the replacement of the polytainer can be performed with a margin. The lighting of the lamp 17 and the buzzer alarm can be stopped by the operator pressing the reset button.

The forward / reverse drive of the rotary actuator 51 is performed by the sequencer 31 at a predetermined timing. This will be described with reference to the flowchart of FIG.

The flowchart of FIG. 4 is started by the operation of the synthetic resin injection molding machine 3 and firstly, step S
In step 1, a controller N built in the synthetic resin injection molding machine 3 sets a specified number N of products to be accommodated in the polytainer.
Further, the delay time T in the sequencer 31 is set. The delay time T is the time from when the product W is molded in the synthetic resin injection molding machine 3 and the number of products is counted to when the product W reaches the polytainer. Thus, the specified number of products W can be simply and reliably stored without waste so as not to forget to count products that are being discharged.

Next, in step S2, the molding machine 3 counts the number of products W each time it is molded, and reads the product count number n by its controller.

Next, in step S3, the controller of the molding machine 3 determines whether or not the product count number n is equal to the prescribed product number N. If the product count number n is smaller than the product number N, the process proceeds to step S2. The reading of the product count n is continued. If n is equal to N, the input number completion signal is output from the molding machine 3 in step S4, and the sequencer 31 starts counting time t in step S5. Then, it is determined whether or not the counted time t is equal to the set delay time T in step S6. If t has not reached T, the counting of t is continued in step S5, and if equal, the air solenoid valve 57 is determined in step S7. , Lamp 1
7, and a signal is sent to the buzzer. Thereby, the air solenoid valve 57 is switched, and the rotary actuator 51 is driven by the air from the compressor 59,
The inversion of the inversion shooter 27 is performed. Lamp 1
The lighting of 7 and the buzzer alarm are also performed. Such control is performed during the entire operation of the synthetic resin injection molding machine 3.

The discharge of the runner R is carried to the runner discharge port 11 by the roll 9 as in the case of FIG.

The present invention is not limited to the above embodiment. For example, the dispensing machine 21 has the runner outlet 1
1 and can be used for replacement of the runner storage case 15. Further, the present invention can be applied to apparatuses other than the molded article separating apparatus in the synthetic resin injection molding machine.
