Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing equipment, and more specifically to a safety control system suitable for storage cabinets. Background Art

[0002] In the tobacco processing process, the tobacco leaf and tobacco storage cabinet is one of the important equipment. It is used on the process line to store and adjust the processed tobacco leaves and tobacco, balance the production process and meet the process requirements.

[0003] The working states of the storage cabinet include "waiting for materials", "storing materials", "feeding materials" and "discharging materials". In the "feeding materials" state, the auxiliary material vehicle, driven by the transmission device, reciprocates on the track on the upper part of the cabinet, and scatters the conveyed materials on the conveyor belt of the cabinet in a straight line or layer by layer. In the "discharging materials" state, the electric control cabinet controls the conveyor chain belt transmission device and the consumption roller transmission device to start, and the conveyor chain belt conveys the materials to the discharge port, and the consumption roller consumes the materials evenly until the discharge is completed.

[0004] However, traditional tobacco leaf and cut tobacco storage cabinets have some safety issues during the production process, such as:

[0005] (1) Since the cabinet door has a safety interlock control, the operator may accidentally open the cabinet door during the operation of the cabinet, causing the upstream or downstream equipment to shut down and causing process quality accidents.

[0006] (2) When the operator enters the storage cabinet or exits the cabinet, he may collide with moving equipment such as the fabric cart and rollers, causing a safety accident.

[0007] A safety protection system and method for a storage cabinet and a storage cabinet are provided, which relate to the field of tobacco processing safety. A human body recognition device is arranged within 2 meters from a material-discharging roller at a discharging end of the storage cabinet. When a person is in the detection area of ​​the human body recognition device, an alarm signal is sent to a control system, and the control system controls the movement state of the material-discharging roller according to the alarm signal, thereby realizing safety protection of the personnel in the storage cabinet.

[0008] However, the existing technology cannot prevent the cabinet door from being opened by mistake during the feeding and unloading stages, causing the cabinet and upstream and downstream equipment to shut down, or even cause safety accidents. Therefore, how to design a safety control system that can prevent the cabinet door from being opened by mistake is a technical problem that urgently needs to be solved in this technical field.
