Abstract
Description
Technical Field
[0001] The utility model relates to the field of transmission devices for tire production, and more specifically, to an anti-over-position device for the embryo conveyor belt when leaving the warehouse. Background Art
[0002] As is well known, with the development and maturity of automated equipment, automated equipment in the tire field is indispensable, and automated logistics equipment for auxiliary production has also been widely used in tire production. When the embryo needs to interact with other logistics equipment during the conveying process on the conveying line, unexpected troubles may occur due to different specifications of the embryos. After the tire is scanned and recorded when leaving the warehouse, the hanging basket of the transport cart for pulling the embryo will descend and sink below the conveyor belt. At this time, the embryo will be conveyed to this station and stop relying on the induction photoelectric on the conveyor belt. However, due to the large number of specifications and diverse embryo sizes on site, a single photoelectric cannot ensure the stopping position of the embryo. This will cause embryos of different sizes to stop at different positions. When the hanging basket rises after the embryo receives the signal allowing it to rise from the conveyor belt, the position of the embryo in the hanging basket will be different, resulting in the situation of the embryo being over-positioned in the hanging basket (although the position of the photoelectric can be moved backward, there will be problems such as the embryos not being conveyed in batches to the correct position and the inability to transmit the signal for the hanging basket to rise). When the aerial transport cart is in the process of transportation, there may be situations where the embryo scratches the guard net at the tire unloading port or the embryo is thrown off when the cart turns, posing a huge safety hazard to personnel and equipment. Summary of the Invention
[0003] In order to overcome the deficiencies of the prior art, the utility model provides an anti-over-position device for the embryo conveyor belt when leaving the warehouse, which solves the problems of scratching and being thrown off caused by different specifications of embryos, resulting in different stopping positions of the embryos on the conveyor belt and different positions of the embryos entering the hanging basket of the aerial transport cart, ensuring the normal operation of the equipment and avoiding the safety hazard of the embryo falling from a height.
[0004] The technical solution adopted by the present utility model to solve its technical problems is as follows: A device for preventing over-positioning of a tire embryo storage conveyor belt is provided with a cloth conveyor belt. The feature is that a conveying roller conveyor belt is arranged in front of the cloth conveyor belt. An optoelectronic switch is installed in the middle part of the cloth conveyor belt, and the optoelectronic switch is connected to the input module of the PLC through a connecting wire; A detection-in-place optoelectronic switch is installed at the rear part of the conveying roller conveyor belt, and the detection-in-place optoelectronic switch is connected to the input module of the PLC to transmit the detection signal to the PLC; A stop optoelectronic switch is installed in the middle part of the conveying roller conveyor belt, and the stop optoelectronic switch is directly connected to the input module of the PLC; A cylinder is installed at the front position below the conveying roller conveyor belt. A cylinder lower magnetic switch and a cylinder upper magnetic switch are respectively installed at the lower part and the upper part of the cylinder. The cylinder lower magnetic switch and the cylinder upper magnetic switch are connected to the input module of the PLC through connecting wires. A free roller is installed on the telescopic rod of the cylinder; An EMS trolley is installed directly above the front part of the conveying roller conveyor belt through an EMS trolley track. An EMS trolley hanging basket is suspended on the EMS trolley. The PLC is wirelessly connected to the EMS trolley PLC. When the PLC signal is sent out, it will control the action of the EMS trolley through the EMS trolley PLC.
[0005] The beneficial effect of the present utility model is that it effectively ensures that during the operation of the tire embryo, the situation of over-positioning of the tire embryo transportation will not occur due to tire embryos of different specifications, ensuring that the tire embryo can completely enter the hanging basket lowered by the aerial transportation trolley, avoiding the situation that the tire embryo is scratched and dropped during transportation due to the tire embryo exceeding the edge of the hanging basket, and ensuring the safety of personnel and the normal operation of the equipment. Brief Description of the Drawings
[0006] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0009] In the figure, the present utility model is provided with a cloth conveyor belt 10. In front of the cloth conveyor belt 10, there is a conveyor roller conveyor belt 11. An optoelectronic switch 1 is installed in the middle part of the cloth conveyor belt 10. The optoelectronic switch 1 is composed of an emitting and receiving optoelectronic device and a reflector. The optoelectronic switch 1 is connected to the input module of the PLC through a connecting wire, used to sense the goods position and trigger a signal to the PLC, and is wirelessly connected to the PLC of the EMS trolley. When the PLC signal is sent out, it will control the action of the EMS trolley through the PLC of the EMS trolley. The cloth conveyor belt 10 is driven by a motor through a chain to drive the conveyor roller to rotate, thereby driving the cloth conveyor belt 10 to rotate, and is used to convey the tire blank to the next conveyor roller conveyor belt 11.
[0010] A detection-in-place optoelectronic switch 2 is installed at the rear part of the conveyor roller conveyor belt 11. The detection-in-place optoelectronic switch 2 is composed of an emitting and receiving optoelectronic device and a reflector. The detection-in-place optoelectronic switch 2 is connected to the input module of the PLC, and transmits the detection signal to the PLC. The detection-in-place optoelectronic switch 2 is used to detect whether the tire blank is conveyed to the next conveyor belt in place. Its purpose is to detect the state of the tire blank entering the basket 7 of the MES trolley, and prevent the EMS trolley from transporting the tire blank away when the tire blank is not completely in the middle of the basket of the MES trolley; A stop optoelectronic switch 3 is installed in the middle part of the conveyor roller conveyor belt 11. The stop optoelectronic switch 3 is composed of an emitting and receiving optoelectronic device and a reflector. The stop optoelectronic switch 3 is directly connected to the input module of the PLC. After the stop optoelectronic switch 3 detects the tire blank, it transmits the signal to the PLC, and the PLC controls the motor driving the conveyor roller conveyor belt 11 to stop.
[0011] A cylinder 9 is installed at the front position below the conveyor roller conveyor belt 11. A cylinder lower magnetic switch 4 and a cylinder upper magnetic switch 5 are respectively installed at the lower part and the upper part of the cylinder 9. The cylinder lower magnetic switch 4 and the cylinder upper magnetic switch 5 are connected to the input module of the PLC through a connecting wire, used to detect and feedback the state of whether the cylinder is extended or retracted, so as to stop the signal of the solenoid valve driving the cylinder to act. A free roller 6 is installed on the telescopic rod of the cylinder 9. The function of the cylinder 9 is to drive the free roller 6 to lift. The free roller 6 is installed on the telescopic rod of the cylinder 9, and it has two states: one is the normal state when the telescopic rod of the cylinder 9 rises. When the cylinder 9 rises, the free roller 6 is used to block the situation of the tire blank passing through. The other is that when the barcode scanner fails to identify the tire blank, the tire blank needs to be discharged to the abnormal port, but the unrecognized tire blank also passes through the conveyor roller conveyor belt 11. At this time, the telescopic rod of the cylinder 9 descends, and the free roller 6 is at the same horizontal plane as other driving conveyor rollers.
[0012] An EMS trolley is installed directly above the front part of the conveyor roller conveyor belt 11 via the EMS trolley track 8. An EMS trolley hanging basket 7 is suspended from the EMS trolley. The EMS trolley track 8 is installed and laid in the air in the tire receiving area and extends all the way above the vulcanizer to form a closed-loop track for hanging the EMS trolley and enabling it to move along the track route. The conveyor roller conveyor belt 11 is driven by a motor through a chain to make the conveyor rollers rotate. At the same time, there is a space between the conveyor rollers through which the EMS trolley hanging basket 7 can pass. The EMS trolley hanging basket 7 can be lowered below the horizontal plane of the conveyor roller conveyor belt 11. The EMS trolley is suspended with an EMS trolley hanging basket 7, and the EMS trolley hanging basket 7 is an apparatus for the EMS trolley to carry the tire embryo. When the EMS trolley receives the signal to transport the tire, after the EMS trolley moves to the tire receiving position, the EMS trolley hanging basket 7 descends and exactly drops to the gap between the conveyor rollers of the conveyor roller conveyor belt 11. At the same time, the position of the EMS trolley hanging basket 7 is slightly lower than the horizontal plane of the conveyor roller conveyor belt 11 to facilitate the tire embryo to enter the EMS trolley hanging basket 7.
