The present invention relates to an automatic injection system for a release agent of a blowout robot, which can be applied to various fields, in particular, injecting a release agent automatically for injection molding.

In the past, the release agent injection system was imported from the country or used as a COPY, but the development of a device that can perform the same performance with a simple circuit configuration is expensive, inconvenient to use, and has an import substitution effect. When the injection molding machine was working, the release agent (relaxing agent for smooth injection during injection molding) was sprayed to the place where the worker needed it directly, so that the workability, production yield and work risk (injector operation) were held.

Therefore, the present invention has been made in order to solve the conventional problems as described above, the injection nozzle bracket that can be adjusted in the angle and length adjustment on the Z-axis 11 and the nozzle jig 12 of the take-out robot for the purpose. ) To the nozzle 4 using the pressure of the release agent can and all the control is to be used by the release agent control unit 2 as required by the user, and another object of the present invention is to It is possible to expect the improvement of quality, the reduction of working time and the stability of the work by constructing a simple circuit as the selected cycle counter (C) and each timer and relay so that it can be inserted and used in the alarm control part.

Hereinafter, the configuration of the present invention having such an object will be described in detail with reference to the accompanying drawings.

The control unit 3 is applied to the release agent control unit 2 which is a main control part through the interlock wiring 8, and is connected to the nozzle 4 through the nozzle coil 7 for inputting a control signal and a sensor to the release agent control unit 2. It is a release agent injection system of a take-out robot by installing a liquid detection sensor (9) (9 ') for detecting the amount of release agent is injected on both sides of the nozzle (4), Figure 3 is a detailed circuit diagram of the main control part of Figure 2 according to the present invention The cycle counter (C) for selecting how many times to spray the cycle counter switch (C ') and the self-maintained relay switch (R ₁ ') through pins 5 and 8 according to the input signal (CP). and a delay timer switch (T ₁ ') the relay (H,) by way of the Delay timer (T,) and to be connected to a delay timer switch (T ₁ ˝) and the relay switch (R ₃ ˝) and bunreuk timer switch (Ta ') for controlling the relay (Ra) and the injection time by selecting the STE To the nozzle Nz via a relay switch R, ˝ 'and connected to the nozzle Nz, and a relay switch R, (R ₃ ′ and a spray sensor signal terminal Rs and It connects to the relay R ₃ and the flicker relay 66 which detects whether the release liquid is consumed through the alarm signal stop terminal Pb, and the flicker relay switch 66 'makes the alarm signal terminal B sound the alarm. _Z ) (R _L ), each terminal of which is reset to the cycle counter (C) via the relay switch (R ₂ ').

In the description of the drawings, reference numerals R ₁ ', R ₂ ', -R ₂ 는, R ₃ ′ are relay switches, T ₁ , ', T ₂ 지연 are delay timer switches, and T ₂ ′ is injection timer switch. 66 'is a flicker relay electrical switch.

Hereinafter, the operation and effects of the present invention will be described in detail with reference to the accompanying drawings.

When the release agent box 1 is completely filled with the release agent, the filling to the release agent pipe 6, the release agent distributor 5, and the nozzle 4 is completed. After selecting the start time and injection cycle (available once each time and selectable up to 9999) in the release agent control unit mounted on the release agent control unit 2, the Z-axis 11 of the take-out robot is selected. When the product is taken down and the control signal and the start signal are applied to the nozzle 4 through the nozzle coil 7 in the release agent control unit 2 according to the operator's instructions, the release agent is sprayed from the nozzle 4 to perform the work. do.

After the start signal is input from the nozzle control unit 2 to the nozzle 4, the liquid detection sensors 9 and 9 'installed on both sides of the nozzle 4 operate when the agent is not sprayed even after 0.01 set (SEC) passes. When the release agent control device mounted on the release agent control unit 2 detects that all of the release agent has been consumed, and the lamp 10 mounted on the release agent box 1 emits an alarm sound or flashes as an alarm signal, To replace the new release agent in the release agent box (1) to be able to work.

3 is a detailed circuit diagram of the main controller 13 of the release agent control unit 2, and when a 24V power is applied, the injection cycle of the equipment to be used in the cycle counter C may be sprayed every several times (1-9999). Periodic counter connected to pin 5 and pin 8 of the counter counting signal applied to pin 4 of this equipment when it is equal to the setting of cycle counter (C) according to the input signal (CP) input of the equipment. Since the switch C 'is ON, the relay R ₁ and the delay timer T ₁ are excited and self-sustained by the relay switch R ₁ ′.

Therefore, when the set value of the delay timer (T ₁ ) is reached, the relay (R ₂ ) and the non-timer (T ₂ ) are excited by the delay timer switch (T ₁ ˝) and self-hold by the relay switch (R ₂ ). The relay R ₁ and the delay timer T ₁ are deactivated and the relay R ₂ is turned ON by the delay timer switches T and ˝.

Therefore, since the relay R ₃ is turned on, the relay switch R ₁ is turned on, and a signal is input to the nozzle N2 so that the release agent starts spraying and the spraying time is completed or set. When the injection timer T ₂ , UP is passed, the relay R ₂ and the injection timer T ₂ are decompressed by the injection timer switch T ₂ ′ so that the release of the release agent is stopped at the nozzle Nz.

Next, the alarm device will be described.

When the relay R ₂ is turned ON and the release type injection starts at the nozzle Nz, the injection detection unit 2 mounted at the nozzle Nz transmits the injection detection signal. The sensor signal terminal (R _S ,) is turned on and the injection sensor signal terminal (R _S ,) is turned off when not sprayed. The relay (R ₂ ) is sprayed when it is turned on. When the sensor signal terminal (Rs) is turned on, it is in a normal state. When the relay (R ₂ ) is turned on, when the injection sensor signal terminal (R.) is turned off, the relay (R ₃ ) and the flicker relay are turned off. (66) turns on at the same time.

Therefore, when the flicker relay 66 is turned on, the alarm signal Bz (R _L ) is periodically flickered by the flicker relay switch 66 'to call an operator and call the alarm signal stop terminal Pb. Can be stopped by).

As described above, the present invention can greatly contribute to the automation of robots that eject injection molds because the injection system of the take-out robot is applied to various injectors to improve quality, shorten the working time and improve the stability of the work, and do not require additional equipment. It is.
