Automatic gate and gate control system for warehouse

Abstract

The invention discloses an automatic gate for a warehouse and a gate control system, and belongs to the technical field of access control. The automatic gate comprises a door frame and a PLC; pieces of U-shaped guiding groove steel are arranged on the adjacent frames of the door frame correspondingly, a pair of transverse toothed plates or a pair of longitudinal toothed plates are arranged in thepieces of U-shaped guiding groove steel in a sliding fit mode, and the transverse toothed plates and the longitudinal toothed plates slide on the door frame through force of a rack driving mechanism;a power source of the rack driving mechanism is a servo motor, a weighing table is arranged on one side of the door frame, and the PLC is further connected with a gate control unit; and the gate control unit comprises a half-open control subunit and a full-open control subunit, a gate is controlled to be opened half or fully through a hydraulic cylinder and a motor. According to the automatic gate, passing transporters and shovel cars in the warehouse are controlled through half opening or full opening of the gate, the transporters are weighed and metered, overweight travelling of the transporters is prevented, thus the shovel car with the small size travels in a gap between the longitudinal toothed plates, and the number of times of opening of the gate is decreased.

Description

technical field [0001] The invention belongs to the technical field of access control, in particular to an automatic gate for a warehouse and a gate control system. Background technique [0002] At present, referring to the prohibition authority of the "door" is the guard against the "door". The "door" here, in a broad sense, includes all kinds of passages that can pass, including doors for people and vehicles. Therefore, access control includes vehicle access control. In the application of parking lot management, vehicle access control is an important means of vehicle management. In the process of warehouse management, due to the transportation of goods, the entry and exit are relatively ordinary, and the doors of large warehouses are relatively large, making the production of warehouse doors more expensive. Moreover, it is not convenient to open, and during the transfer, the loading of the goods is inconvenient to supervise, and most of the freight is easy to carry overw...

Problems solved by technology

In the application of parking lot management, vehicle access control is an important means of vehicle management. In the process of warehouse management, due to the transportation of goods, the entry and exit are relatively ordinary, and the doors of large warehouses are relatively large, making the production of warehouse doors more expensive. And it is not convenient to open, and when the cargo is transferred, it is inconvenient to supervise the loading of the cargo, and most of the cargo is easy to carry overweight for the sake of earning more.
