Embodiment Construction
[0036] Such as Figure 1-3 As shown, the first-generation multi-layer drawer centralized weighing material management cabinet invented by the company includes a cabinet body 5, a cabinet body bottom frame 3, and a control measurement module 1. The cabinet body 5 is set on the cabinet body bottom frame 3. A number of drawers 2 for storing materials are arranged in the cabinet 5; materials or parts are placed in different drawers according to their types. A set of weighing units is installed in the cabinet bottom frame 3 to measure the weight of the entire material management cabinet in real time; the material drawer is locked on the cabinet 5 by an electric control lock, and the user's identity can only be confirmed by the identification unit The drawer is automatically opened by the electric lock.
[0037] The control measurement module 1 includes an upper computer, an identification unit and several lower computers; each lower computer is located in the material management cabin...

The invention discloses a material management cabinet capable of realizing high-sensitivity centralized weighing and counting. The material management cabinet comprises a cabinet body, a cabinet bodyunderframe, an auxiliary supporting unit and a control measurement module; the cabinet body is arranged on the cabinet body underframe; the cabinet body is internally provided with a plurality of drawers which are stacked and used for storing materials; the cabinet body underframe is provided with a weighing unit for measuring the weight of the whole material management cabinet in real time; the auxiliary supporting unit applies an upward constant supporting force to the cabinet body underframe, and the amplitude value of the supporting force is smaller than the weight of the cabinet body underframe without the materials; and the control measurement module is used for controlling the opening of the drawers, calculating the amount of the materials in the material management cabinet according to parameters of a weighing sensor and displaying the amount. The auxiliary supporting mechanism is capable of generating the upward constant supporting force for the cabinet body in a measurement process, so that most of self-weight of the cabinet body can be balanced, the load range of the sensor can be reduced without affecting the measurement precision, and the measurement range of the sensor can be effectively reduced.
Description
Technical field [0001] The invention belongs to the technical field of storage management systems, and relates to an intelligent material management cabinet, in particular to a high-sensitivity material management cabinet that is stacked and centrally weighed. Background technique [0002] In the management of materials and parts in high-end intelligent manufacturing and maintenance industries, there are shortcomings such as low labor efficiency, untimely replenishment of parts and materials, and inaccurate quantity statistics, which cannot satisfy the standardization and refined management of materials and parts in and out of the warehouse. Requirements, for this has produced intelligent material management technology. [0003] The Chinese patent "Material Management Device, Application No. 201610303077.5" discloses a material management device, including a drawer-type material cabinet. The material cabinet includes a box-type shell and a number of drawers. The drawers are provide...
