Description

Control mechanism of pneumatic gripper of prize machine

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

Press, the familiar common clip game machine is mainly using a mobile crane equipped with clamping jaws, coupled with a hanging clamping jaw to fall down, and use the clamping jaws to grab prizes (such as dolls, 3C products …, Etc.), and then use the movement of the crane to move the gripper of the winner to the blanking port to loosen it, so as to obtain the prize of the game.

However, the grippers of the conventional clamp game machines are all powered by the action of the solenoid valve, so the grip force of the grippers is limited, and it is impossible to clamp the large or heavy prizes, which leads to the contents of the clamp game machines. Restrictions.

In order to overcome this deficiency, some industry players have tried to increase the grip of the gripper by increasing the size of the solenoid valve; however, this action has caused the loss of the benzene weight of the solenoid valve, overheating of the circuit, and power consumption.

In addition, the industry has also proposed the technology of pneumatic grippers, which are pushed by a high-pressure gas, so that the pneumatic grippers have sufficient power to grasp heavy objects. Although the pneumatic gripper can achieve the purpose of grasping heavy objects, a single stable and stable high-pressure gas allows the pneumatic gripper to have excellent gripping force, leading to an excessively high loss rate for the operator, which is contaminated by the operator and is not allowed. use. If you provide a low-pressure low-pressure gas, although the gripping force of the pneumatic gripper can be limited, the excessively weak clamping force will appear obvious. As a result, consumers believe that the game is malfunctioning and lose their willingness to consume.

Therefore, how to achieve a balance between the probability of the consumer and the industry, without the obvious lack of action of the pneumatic gripper, it is obviously necessary to improve its control method of working air pressure.

In view of the problems and shortcomings of the above-mentioned conventional techniques, the main purpose of the present invention is to provide a control mechanism for the pneumatic gripper of the prize machine. Through the design of the structure, based on the probability or preset procedures, it can selectively output different pressures. The working gas allows the pneumatic grippers to exhibit different gripping force responses, increasing the variability and probability of the game.

According to the above object of the present invention, the present invention proposes a control mechanism for a pneumatic gripper of a prize machine, which includes a pneumatic gripper assembly, a control unit, an air supply unit and a high-pressure runner unit electrically connected to the control unit. , An intermediate pressure flow channel unit, a low pressure flow channel unit, and a pressure relief flow channel unit. The pneumatic gripper assembly is operated 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 regulate driving gas to form high, medium, and low-pressure working gases, and are triggered to output to a pneumatic gripper assembly. The pressure-releasing flow channel unit is triggered to communicate with the pneumatic gripper assembly to prevent leakage. The control unit is a unit that selectively triggers electrical connection. With the composition of the upper member, the working pressure of the pneumatic gripper assembly is output at different pressures, and the power of the gripper is adjusted.
