Description

Non-blind area safety touch edge strip

Technical Field

The utility model relates to a sealing strip technical field, concretely relates to non-blind area safety touches strake.

Background

The safety contact edge, also called safety edge, is a belt-shaped pressure-sensitive switch. The safety edge and the safety buffer are flexible and bendable belts which can be fixed on the edge of moving parts such as machine tool working tables and electric doors, which are in danger of extrusion and shearing.

1. When the moving parts with safety edges or buffers are impacted to the operator (or the operator is impacted to the moving parts), the flexible safety edges are pressed and send signals to the power source to stop the movement of the parts.

2. The safety edge or safety buffer may be classified as a "belted" device. The security edge or security buffer does not restrict access but merely "feels" it. The safety edge and the safety buffer are completely dependent on their sensing and switching capabilities to provide safety protection, so reliable control of the control circuit of the safety edge or the safety buffer is very important. Safety edges or bumpers are typically used only on machines where the moving parts can stop immediately after power is removed.

3. The safety edge or buffer together with the controller constitutes a flexible and versatile emergency stop system, which the machine operator or installer must be able to stop the towing installation easily and with ease.

At present, when an AGV unmanned vehicle, a lifting platform, a stage, a movable door and the like are used, moving objects can very possibly touch people and injure users. In order to achieve the technical requirement of preventing from injuring or colliding users, the obstacle state is generally known by detecting the current parameter of the motor, or an anti-pinch strip is arranged, so that the obstacle state can be more directly known, and meanwhile, the injury to the users is greatly reduced. Present prevent pressing from both sides a structure, prevent pressing from both sides the part and suffer the collision extrusion in the use, only conductive part warp, prevent pressing from both sides the part because inside supports or the edge is difficult to for the linear type warp, also can cause the injury to the user, new national standard not only requires to prevent pressing from both sides the strip and can extrude electrically conductively, requires simultaneously to warp easily.

The utility model discloses a strip is prevented pressing from both sides by sliding door in application number CN207241378U, discloses a strip is prevented pressing from both sides by car electrically operated gate in application number CN201210543601.8, but should prevent that strip resistance range is little, is unfavorable for discerning.
