Description

Technical Field

[0001] The utility model relates to the field of photoelectric fixing structures, in particular to a photoelectric fixing structure of a stereoscopic warehouse conveying line. Background Art

[0002] The high-bay warehouse is an efficient and automated warehousing system that maximizes space utilization and enables quick access to items through vertical storage and mechanized operations.

[0003] However, the existing photoelectric fixed structure of the stereoscopic warehouse conveyor line has the following disadvantages:

[0004] (1) The existing stereoscopic warehouse conveyor line in-place photoelectric fixing method is to fix it with the conveyor line as a whole. However, when the conveyor line is docked with the trolley, the conveyor line will shake, causing the photoelectric irradiation beam to leave the reflector range, generating an error signal. The host computer mistakenly believes that the task has completed the interaction with the conveyor line, but the actual position of the empty pallet is between the trolley and the conveyor line. It has not completely left the trolley's operating range and has not reached the in-place photoelectric position.

[0005] (2) At the same time, because the over-limit photoelectric illumination position of the trolley is relatively low, there is a phenomenon of penetration, so the trolley does not alarm. When the trolley receives a new task and runs, it will hang on the empty pallet, causing a tray failure. Utility Model Content

[0006] The purpose of the utility model is to provide a photoelectric fixed structure of a stereoscopic warehouse conveyor line to solve the existing problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a photoelectric fixed structure of a three-dimensional warehouse conveyor line, comprising a floor, a conveyor is installed on one side of the top of the floor, a vehicle body is provided on the other side of the top of the floor, a photoelectric bracket is installed on one side of the top of the floor in front of the conveyor, a lifting mechanism 1 is installed on the top of the photoelectric bracket, a fixed frame is installed on the top of the lifting mechanism 1, a conveyor line in place photoelectric is installed on the top of the fixed frame, a lifting mechanism 2 is installed on the front of the vehicle body, an L-shaped column is installed on the top of the lifting mechanism 2, a fixing part 1 is installed on one side of the top of the L-shaped column, a fixing part 2 is installed on the other side of the top of the L-shaped column, a trolley in place photoelectric is installed on the top of the fixing part 1, and a trolley protection photoelectric is installed on the top of the fixing part 2.

The bottom of the sleeve rod is rotatably connected to the rotating member via a ball bearing, and one end of the rotating member passes through the inner wall of the sleeve rod and is fixedly connected to the second bevel gear. The lifting mechanism is used to adjust the height of the photoelectric device.

[0011] As a preferred technical solution of the present invention, the bottom end of the threaded rod is rotatably connected to the bottom end of the inner wall of the sleeve rod through a damping bearing. The damping bearing prevents the threaded rod from rotating due to the gravity of the photoelectric device and its bracket.

[0014] As a preferred technical solution of the present invention, the sliding block is slidably connected to the inner wall of the sliding groove. The lifting rod can slide up and down on the inner wall of the sleeve rod.

[0015] As a preferred technical solution of the present invention, a back frame is installed on one side of the top of the floor behind the conveyor, and a reflector is installed on the top of the back frame. The reflector is used to receive the light beam emitted by the photoelectric device and reflect it back.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By installing an independent photoelectric bracket on the outer edge of the conveyor line, the photoelectric signal is not affected by the shaking of the conveyor line during operation, avoiding photoelectric signal errors caused by the shaking of the conveyor line, effectively reducing the failure rate and ensuring the normal operation of the equipment;

[0018] 2. By uniformly raising the trolley arrival photoelectric, trolley protection photoelectric, and conveyor line arrival photoelectric to a certain height, the light beam from the signal transmitter is irradiated onto the flat surface of the upper edge of the pallet, thereby improving the accuracy of the photoelectric signal, reducing more serious equipment and personnel safety issues caused by tray failures, and improving the safety of vertical warehouse operations, thus contributing to achieving safety efficiency, cost reduction, and efficiency improvement.

[0026] During use, by installing an independent photoelectric bracket 5 on the outer edge of the conveyor line, the photoelectric signal is not affected by the shaking of the conveyor line during operation, avoiding photoelectric signal errors caused by the shaking of the conveyor line, effectively reducing the failure rate and ensuring the normal operation of the equipment.

[0027] A pallet 4 is placed on the top of the vehicle body 3, and the conveyor line arrival photoelectric 6, the trolley arrival photoelectric 11 and the trolley protection photoelectric 13 are on the same horizontal line with the top of the pallet 4 to improve the detection accuracy. A back frame 7 is installed on one side of the top of the floor 1 behind the conveyor 2, and a reflector 8 is installed on the top of the back frame 7 to reflect light.

[0028] When in use, the trolley in position photoelectric 11, the trolley protection photoelectric 13, and the conveyor line in position photoelectric 6 are uniformly moved up a certain height so that the light beam from the signal transmitting end is irradiated onto the flat part of the upper edge of the pallet 4, thereby improving the accuracy of the photoelectric signal. The reflective plate 8 is used to cooperate with the conveyor line in position photoelectric 6 to detect the presence or absence of the pallet 4.

[0029] The lifting mechanism 14 and the lifting mechanism 2 16 both include a sleeve rod 17, a threaded rod 18, a lifting rod 19, a bevel gear 1 20, a bevel gear 21 and a rotating member 22. A threaded rod 18 is installed inside the sleeve rod 17. The top of the threaded rod 18 is threadedly connected to the inner wall of the lifting rod 19.

Since the top of the threaded rod 18 is threadedly connected to the lifting rod 19, and under the guidance of the slider 23 and the slide groove 24, the lifting rod 19 can move vertically, which can change the position of the photoelectric device above. The damping bearing 25 provided can prevent the threaded rod 18 from rotating due to the gravity of the photoelectric device and its bracket.

By installing an independent photoelectric bracket 5 on the outer edge of the conveyor line, the photoelectric signal is not affected by the shaking of the conveyor line during operation, thereby avoiding photoelectric signal errors caused by the shaking of the conveyor line. By rotating the rotating part 22 of the lifting mechanism, the threaded rod 18 can be driven to rotate with the cooperation of bevel gear 21 and bevel gear 1 20. Since the top of the threaded rod 18 is threadedly connected to the lifting rod 19, and under the guidance of the slider 23 and the slide groove 24, the lifting rod 19 can move vertically, which can change the position of the upper photoelectric. The trolley in-position photoelectric 11, the trolley protection photoelectric 13, and the conveyor line in-position photoelectric 6 can be uniformly moved up to a certain height, so that the light beam of the signal transmitting end is irradiated to the upper flat part of the tray 4, thereby improving the accuracy of the photoelectric signal. The damping bearing 25 provided can prevent the rotation of the threaded rod 18 due to the gravity of the photoelectric and its bracket.
