Description

Control mechanism of prize machine pneumatic gripper

The invention relates to the technical field related to a game machine, in particular to a control mechanism of a prize machine pneumatic gripper.

Press, the commonly known clip game machine mainly uses a mobile crane equipped with grippers, and a suspended gripper hangs up and down, and uses the grippers to grab prizes (such as dolls, 3C products) ...And so on), and then move the gripper using the crane to move the gripper that holds the prize to the blanking port and release it to obtain the prize of the game.

Of course, the gripping force of the conventional gripping game machine comes from the action of the solenoid valve, so the gripping power of the gripping claw is limited, and it is unable to grasp large or heavy prizes, resulting in the content of the prizes of the gripping game machine Limitations of things.

In order to overcome this shortcoming, there have been attempts to increase the gripping power of the gripper by increasing the size of the solenoid valve; however, this has caused the solenoid valve to become heavy, the circuit is overheated, and the power consumption is missing.

In addition, the industry has also proposed the technology of pneumatic gripper, which is pushed by a high-pressure gas, so that the pneumatic gripper has enough power to grab heavy objects. Although the pneumatic gripper can achieve the purpose of grabbing heavy objects, a single stable and stable high-pressure gas gives the pneumatic gripper an excellent grip, resulting in an excessively high loss rate of the industry, and the industry is ridiculed by it. use. Moreover, if a lower pressure gas is provided, although the gripping force of the pneumatic gripper can be restricted, the gripping force that is too weak will be obvious. As a result, consumers think it is a malfunction of the clip-in game machine and lose their willingness to consume.

Therefore, how can the probability balance between the consumer and the industry be achieved without obvious insufficient action of the pneumatic gripper? The control method of the working air pressure obviously needs to be improved.

In view of the problems and deficiencies of the above-mentioned known techniques, the main purpose of the present invention is to provide a prize machine pneumatic gripper control mechanism, which can selectively output different pressures based on probability or preset procedures through structural design The working gas makes the pneumatic gripper show different grip response, increasing the variability and probability of the game.

According to the above objective of the present invention, the present invention proposes a prize machine pneumatic gripper control mechanism, which includes a pneumatic gripper assembly, a control unit, an air supply unit electrically connected to the control unit, and a high-pressure runner unit , A medium pressure flow channel unit, a low pressure flow channel unit, and a pressure relief flow channel unit. The pneumatic gripper assembly is actuated by a working gas. The gas supply unit is triggered to provide a driving gas. The high-pressure runner unit, the medium-pressure runner unit, and the low-pressure runner unit adjust the driving gas to form high, medium, and low-pressure working gas, and are triggered to output to the pneumatic gripper assembly. The pressure relief flow channel unit is triggered to communicate with the pneumatic gripper assembly to prevent leakage. The control unit selectively triggers each unit of electrical connection. With the composition of the upper component, the pneumatic gripper assembly can output different pressures of working air pressure to adjust its gripping force.
