Detailed Description

The present invention will be further explained with reference to the drawings and the embodiments.

Referring to fig. 1, the utility model provides a tire building machine safety protection system: the device comprises a mechanical railing arranged at the periphery of a tire building machine, a first safety light curtain arranged in a translational motion region of a tail stock cloth expander and a positive and negative wrapping device of the tire building machine, a second safety light curtain arranged between the tail stock of the tire building machine and a host, a region scanner arranged at one side of the tail stock of the tire building machine and used for scanning a sector region in which the cloth expander rotates, and safety contactors arranged at the edges of two sides of a transfer ring of the tire building machine, wherein one safety contactor is arranged in the direction of the machine head and the direction of a case; a safety control PLC and an emergency stop device; the safety PLC is respectively connected with the mechanical handrail, the first safety light curtain, the second safety light curtain, the safety contactor, the area scanner and the emergency stop device.

In this embodiment, the mechanical handrail is provided with a passage safety door; the emergency exit is provided with the mock safety door lock, the safety door lock is connected with safe PLC, can realize access protection, and the real time monitoring lock situation, in case someone gets into, the information feedback of safety door lock to safe PLC, can controlgear's running state through logic programming to reach the control that prevents the mistake and go into or the maintenance is shut down.

In the embodiment, the safety control PLC adopts a Siemens S7-1515F safety PLC.

In this embodiment, safety contactor adopts the Qingdao to touch the limit safely, and equipment moving part is the machinery with human contact and is the collision, increases the safe limit that touches, and when receiving the collision, the signal real-time transfer to safe PLC controls moving part and stops. .

In this embodiment, the area scanner is a SICK area scanner, and is located beside the tailstock and outside the mechanical enclosure, as shown in area D in fig. 1. The SICK safety laser scanner is an advanced proprietary technology, experience and perfect crystallization for optimal performance. The surroundings are scanned and the distance is measured. The two-dimensional monitoring result of an arbitrarily defined protected area can be generated by means of the integrated rotating mirror. And the monitoring result is fed back to the safe PLC, and the rotating fan-shaped area of the cloth expanding device can be controlled through the safe laser area scanner, so that the damage of the equipment to personnel caused by the mistaken entry of the personnel is effectively prevented.

In this embodiment, the safety light curtain adopts a SICK safety light curtain: one is located in the translation movement area of the tailstock spreader and the front and back packaging device, such as area B in figure 1, and the other is located between the tailstock of the forming machine and the host machine and is a necessary part for entering the operation area, such as area C in figure 1. In the area without a mechanical fence, a safety light curtain is added, access protection is set, and the safety of personnel entering and exiting in the operation process of equipment is guaranteed.
