[0028] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0029] like Figure 1 The structure shown in this utility model is a safe operation system for a finishing automatic baling machine in high-speed wire production. The finishing automatic baling machine includes a PLC, two baling machine compaction carriages, and a C-shaped hook 6 located between the two baling machine compaction carriages.

[0030] In order to solve the problems and overcome the defects of the existing technology, and to achieve the invention objective of preventing unauthorized personnel from entering the bundling production process and causing safety accidents, the technical solution adopted by this utility model is as follows:

[0031] like Figure 1 As shown, the safety operation system of the finishing automatic bundling machine in the high-speed wire production of this utility model is provided with a photoelectric sensing device at the entrance of the finishing automatic bundling machine.

[0032] The purpose of this utility model's safety-type automatic baling machine photoelectric sensing device is to achieve personal safety protection for personnel entering and stopping the machine during automatic operation by installing and modifying an automatic sensing detection interlocking system; without operator intervention, the photoelectric sensing system automatically triggers the interlock to achieve safe baling, which can effectively prevent safety accidents caused by personnel accidentally entering the baling machine's working area, improve the safety and reliability of the baling equipment, and eliminate potential safety hazards.

[0033] Specifically:

[0034] The two baling machine compaction vehicles are designated as Baling Machine Compaction Vehicle 5 (No. 1) and Baling Machine Compaction Vehicle 7 (No. 2). The photoelectric sensing device includes two photoelectric sensor transmitters and two corresponding photoelectric sensor receivers. The two photoelectric sensor transmitters are designated as Left Photoelectric Sensor Transmitter 9 and Right Photoelectric Sensor Transmitter 1, and are distributed on the left and right sides of Baling Machine Compaction Vehicle 5. The two photoelectric sensor receivers are designated as Left Photoelectric Sensor Receiver 10 and Right Photoelectric Sensor Receiver 4, and are distributed on the left and right sides of Baling Machine Compaction Vehicle 7.

[0035] Infrared sensors are installed at the entrances on both sides of the baler. An automatic sensing and detection interlocking system is distributed on both sides of the two balers, and two induction diffuse reflection baffles are installed to improve the accuracy of monitoring and ensure that personnel are prevented from entering the baling production area from both directions.

[0036] The left photoelectric sensor transmitter 9, the right photoelectric sensor transmitter 1, the left photoelectric sensor receiver 10, and the right photoelectric sensor receiver 4 are respectively connected to the PLC through a control circuit.

[0037] The photoelectric sensor signal processing unit (PLC) of the safety-type automatic baling machine can accurately identify the signal characteristics of personnel entering and transmit the signal to the safety control module in a very short time, and issue an audible and visual alarm.

[0038] The left photoelectric sensor transmitter 9, the right photoelectric sensor transmitter 1, the left photoelectric sensor receiver 10, and the right photoelectric sensor receiver 4 are all positioned at a height of 30-50cm above the ground.

[0039] The installation height is set at 30-50cm to ensure that the movement and entry of ordinary people (including related items) can be identified and judged.

[0040] Based on the above technical solution, install two more confirmation buttons and one set of audible and visual alarm equipment:

[0041] The safety operation system is equipped with two confirmation buttons, namely the left confirmation button 8 and the right confirmation button 2, which are respectively arranged on the left and right outer sides of the left photoelectric sensor transmitter 9 and the right photoelectric sensor transmitter 1.

[0042] The left confirmation button 8 and the right confirmation button 2 are respectively connected to the PLC through a control circuit.

[0043] After personnel leave the baling area and press the confirmation button, and the baler operator confirms again on the operating interface, the baler can resume automatic baling operation.

[0044] An audible and visual alarm 3 is installed on the No. 1 baler compaction vehicle 5; the audible and visual alarm 3 is connected to the PLC through a control circuit.

[0045] When personnel enter or remain in the bundling production area, the audible and visual alarm 3 will sound an alarm, prompting the operator to take safety measures and stop the equipment.

[0046] The control center of the finishing automatic baling machine is equipped with a PLC operation interface; through the PLC operation interface, the operator performs safety control on the safety operation system.

[0047] The operator performs interlock programming on the PLC; sets the infrared sensor parameters according to the length of the baler, realizes the human body trigger sensor switch output signal, and sends the signal to the baler PLC; when a person enters the baling area and triggers the signal, the program interlock automatically controls the baler to immediately execute the stop action, the baler stops and at the same time issues an audible and visual alarm, and a confirmation window alarm pops up on the baler operation interface.

[0048] This invention effectively solves the safety protection problem of automatic baling machines being unable to identify personnel entering the baling area during operation. It realizes the function of automatically triggering the baling equipment to stop and alarm when personnel accidentally enter the baling area during automatic operation, thereby improving the inherent safety of the equipment.

[0049] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
