Description
Technical field
The invention belongs to intelligent storage technical fields, relate in particular to a kind of intelligent racking system.
Background technique
It is particularly significant to production efficiency is improved to sort accuracy rate and sorting efficiency for basis of the material as production.It is existing
Factory in material allocation mainly using tradition material frame, the course of work is as follows: 1, material stock: the two dimensional code-on barcode scanning charging tray
Charging tray is put will barcode scanning gained two by the empty place-of barcode scanning in entering bin for the estimated place of being put into vacancy two dimensional code-on barcode scanning material frame
Input system-system records the material position after a two dimensional code binding.2, feeding: manual entry in system/distribute work order-material automatically
Position position indicator it is bright-scanning material frame bright light position two dimensional code-scanning material frame on bright light position storage charging tray on two
Dimension code --- take the charging tray away, system saves operation note.This scheme the problem is that: needed in blowing and reclaiming process
Barcode scanning is carried out to charging tray and material frame respectively while needing to bind barcode scanning result, time cost is excessively high;During access material
Risk of error is higher;Safety is poor, can not accomplish anti-theft and loss;When the existing two dimensional code on charging tray can not be used directly
When need secondary patch code, reduce the efficiency of management;The quantity of material on current material frame can not be counted.Therefore, how one is developed
The novel intelligent racking system of kind is the direction that those skilled in the art need to study to overcome the above problem.
Summary of the invention
The object of the present invention is to provide a kind of intelligent racking systems, can be improved the working efficiency of material stock and feeding, reduce
Artificial and Material Cost prevents material from placing mistake and appropriating public property for personal use and puts steathily, saves material storage record, promotes the efficiency of management.
The technical scheme adopted is as follows:
A kind of intelligence racking system comprising: material frame, input unit, controller and writing station;The material frame is equipped with
Multiple placement positions;A sensor and an indicator light are respectively equipped at each placement position;Each sensor respectively with controller
It is electrically connected, for incuding locating placement position in real time and exporting inductive signal to controller when the placement position is placed with material;Institute

It is made of the material removed;;The controller includes Database Unit, sensing unit, transmission unit, coding unit, storage list
Member, indicating unit and delete menu member;The Database Unit is used to store the location information of each sensor and each indicator light;It is described
When sensing unit is used to read the inductive signal of each sensor output;The transmission unit is used to read the material of input unit output
Disk information;The coding unit connection sensing unit, Database Unit and transmission unit, for the sensing of inductive signal will to be exported
The location information of device and the charging tray information are bound and generate material stock information;The storage unit connection coding unit is used
In the material stock information that storage coding unit generates;The indicating unit connects writing unit, storage unit and Database Unit, uses
In the reading work order and search the indicator light for meeting the location information of the charging tray of work order and lighting positioned at the position;It is described to delete
Menu member connects writing unit, storage unit and transmission unit, for what is exported after reading in the work order, based on input unit
Charging tray information deletes corresponding material stock information from storage unit;The input unit includes code reader and information two dimensional code;Institute
It states information two dimensional code to be fixed on charging tray, the code reader is electrically connected with the controller.
By using this technical solution, material stock process is as follows: being identified, is expected to charging tray information with information two dimensional code
Disk information includes the material information that it is installed.By code reader to the barcode scanning of the information two dimensional code, by charging tray information export to
In the controller of code reader electrical connection.Charging tray is then put to placement position idle in entering bin, the sensor sensing of the placement position
To charging tray and export inductive signal;Coding unit called data library unit, the position based on the sensor for exporting the inductive signal
The two is bound and generates material stock information by information and charging tray information.The material stock information includes: that charging tray location information+charging tray installs
Material information.The material stock information preservation is in storage unit.Its reclaiming process is as follows: passing through writing station manual entry work order
Or system distributes work order automatically, indicating unit, which is searched to install according to the work order, to be met the charging tray of material in work order, then lights
Indicator light positioned at the charging tray present position.Employee removes charging tray from material frame according to the indicator light;Employee scans charging tray letter again
Breath;It deletes charging tray information of the menu member after reading in work order, based on input unit output and deletes the charging tray information from storage unit
Corresponding material stock information.
In above process, only need to sweep a subcategory number to charging tray, at the same by sensor sensing its material frame be put into position
It sets and generates position in systems automatically, and automatically record position number, therefore can accurately save material stock information, improve management effect
Rate.Without the secondary patch code in the scene of carrying out, reduce secondary patch code bring Material Cost and cost of labor.
Preferably, in above-mentioned intelligent racking system: further including that alarm, the alarm are electrically connected with the controller;Institute
Stating controller further includes alarm unit;The alarm unit is separately connected sensing unit and transmission unit, in sensing unit
Inductive signal is read to interrupt and without reading in charging tray information and sensing unit without reading induction letter when reading in work order or in transmission unit
Number when activate alarm;The alarm is used for output sound/light alarm when entering state of activation.
By using this technical solution: realizing real time monitoring to each placement position on material frame with sensor.Alarm is single
Member simultaneously monitor sensing unit and transmission unit, when sensing unit read inductive signal interrupt and without read in work order when, illustrate this
When occur appropriating public property for personal use the case where stealing, at this time triggering alarm realize overcomes the problems, such as that in the prior art appropriate public property for personal use steals.And when transmission is single
Member reads in charging tray information and sensing unit illustrates occur the case where not being put into material actually at this time, at this time without inductive signal is read
Triggering is alarmed to guarantee the accuracy rate of material stock.
