Automatic anti-collision device for packaging machine platens

Abstract

The invention relates to an automatic anti-collision device for packaging machine platens. The automatic anti-collision device comprises a PF wire transmission chain, a C-shaped hook, a clamping claw, a PF wire fixing support, a PLC, the packaging machine platens, a photoelectric detection device and an external alarming device. The C-shaped hook is fixed to the PF wire transmission chain in a hung manner. The packaging machine platens are arranged on the packaging machine base below the C-shaped hook. The clamping claw and the photoelectric detection device are fixedly mounted on the PF wire fixing support. The external alarming device is arranged on one sides of the packaging machine platens. A reserved platen opening is formed in the center axis of the top of each packaging machine platen and allows the C-shaped hook in the normal shape at the normal position to pass. The photoelectric detection device is arranged over the reserved platen openings. The photoelectric detection device and the external alarming device are both electrically connected with the PLC. According to the automatic anti-collision device, the position and the shape of the C-shaped hook can be detected automatically, and it is guaranteed that the coil extrusion operation by the platens is prohibited under the risky condition.

Description

technical field [0001] The invention relates to an anti-collision device, in particular to an automatic anti-collision device for the pressure plate of a baler in a steel rolling workshop. Background technique [0002] Finished product packaging equipment (that is, baler) in the steel rolling and wire rod workshop is used to pack the finished steel coils conveyed through the PF line, and then deliver the goods after packing. During the packing operation, when the C-hook carrying the finished coil suspended and fixed on the PF line travels to the central axis of the packing machine, the clamping claw will clamp the C-hook so that the packing operation can be carried out in a static state . At this time, it is necessary for the packaging operator to confirm whether the C-hook is at the central axis of the baler through monitoring or on-site observation, so as to prevent the pressure plate from colliding with the skewed or deformed C-hook (press There is a certain gap reserve...
