Flip type loading and unloading safety device

Abstract

The invention discloses a flip type safe material loading and unloading device which comprises a machining equipment outer shell, wherein a material inlet / outlet is formed in the outer shell; the flip type safe material loading and unloading device is characterized in that a sliding table supported by a stander in a sliding manner is arranged at the material inlet / outlet; a sliding table cylinder capable of driving the sliding table to operate is arranged on the stander in the outer shell; a position, which corresponds to the material inlet / outlet, on the stander in the outer shell is also hinged to a flip body; the flip body is hinged to a flip cylinder in a matched manner; the other end of the flip cylinder is hinged to the stander; a transparent push-pull door is arranged at the material inlet / outlet in a matched manner; a push-pull door cylinder matched with the transparent push-pull door is provided; the sliding table cylinder, the flip cylinder and the push-pull door cylinder can detect extreme position signals of contraction and extension and send the signals to a control system; meanwhile, the sliding table cylinder, the flip cylinder and the push-pull door cylinder are uniformly controlled by the control system.

Description

technical field [0001] The invention relates to a loading and unloading auxiliary device, in particular to a flip type loading and unloading safety device. Background technique [0002] When the machining equipment is processing or assembling the workpiece, the operator needs to cooperate with the machining equipment to load and unload the material: the transport mechanism such as the manipulator on the equipment transports the processed workpiece to the designated position, and the operator removes the workpiece. And place the workpiece to be processed in the specified position. In order to prevent workers from being injured by moving equipment or workpieces during the above operations, a light curtain is traditionally installed at the loading and unloading position. When the light curtain senses that the hands of the worker have entered its own limited The control system of the equipment sends out a signal, and the machining equipment stops the delivery of the workpiece; ...

In order to prevent workers from being injured by moving equipment or workpieces during the above operations, a light curtain is traditionally installed at the loading and unloading position. When the light curtain senses that the hands of the worker have entered its own limited The control system of the equipment sends out a signal, and the machining equipment stops the delivery of the workpiece; however, there are still certain hidden dangers and risks in this way: first, the light curtain may fail and cannot transmit the signal, and the user thinks that the light curtain The curtain is working normally, and is injured by a moving workpiece or a mechanical arm; second, even if the light curtain is not faulty, the light curtain detects the worker's hands and sends the signal to the control system, and the control system controls the actuator to stop Action, the whole process requires a certain reaction time, that is to say, there is a delay in using the light curtain to detect whether the human hand enters the dangerous area, which may still cause the operator to be injured
