Description

A kind of automatically handling material A GV and material handling method
Technical field
The present invention relates to AGV device fields, refer in particular to a kind of automatically handling material A GV and material handling method.
Background technique
The logistics transportation of common production material, finished product is transported using container car, and existing to counter Vehicle carries out cargo, all manually method is completed for the handling of material, this carry out material handling by manual method Mode, the labor intensity of carrying personnel carry material for a long time and are easy to appear production accident.In order to reduce the labour of carrying personnel Intensity, Some Enterprises spent material handling facilities come assist handling material, such as assisted using fork truck handling material, but using pitch Vehicle needs when loading and unloading material using Forklift plate, and Forklift plate can occupy the space of storage material in cabinet case, result in cabinet case It is interior storage material space utilization rate reduce, and Forklift plate purchase and store will increase enterprise production cost and occupy store Space;In addition, needing the enterprise for being equipped with multiple material handling harbours in the enterprising crudely-made articles object of multiple material handling harbours, object The handling of material then need to put into bigger human resources, while configuring more material handling equipments, and production cost is caused to increase Greatly.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of full-automatic handling material A GV, can be used for reality The full-automatic quick despatch of existing material, to save production cost investment.
In order to achieve the above object, it the invention adopts the following technical scheme: a kind of automatically load and unload material A GV, including moves Dynamic docking platform, flexible conveying device and grabbing device;The flexible conveying device and the grabbing device are arranged in the shifting On dynamic docking platform;The grabbing device can be moved synchronously with the extended end of the flexible conveying device, the grabbing device end Extremity piece is equipped with buanch unit, and buanch unit is equipped with vacuum chuck;The grabbing device drives the buanch unit described Material transfer is carried out between flexible conveying device and container car.
Compared with prior art, the full-automatic handling material A GV of one kind of the invention, has the advantage that
(1) after automatically handling material A GV is docked with container car, the flexible conveying device, the grabbing device can be certainly Dynamic to be retractable in cabinet case, the grabbing device carries out material transfer between the flexible conveying device and container car automatically, To realize the full-automatic handling of material, artificial high-intensitive handling material work is replaced completely, reduces the shadow of human factor It rings, it is ensured that the quick despatch of material;
(2) automatically cargo is directly grabbed by the grabbing device, is not necessarily to during handling material A GV handling material Material is carried using assistant carrier, on the one hand, the space that assistant carrier occupies storage material in cabinet case is avoided, so as to Under the premise of not increasing counter tankage, the maximization of the space utilization rate of storage material in cabinet case is realized, on the other hand, Burden caused by enterprise's purchase and storage assistant carrier is decreased, to save production cost;
(3) the extended end synchronizing moving of the grabbing device and the flexible conveying device, makes the work of the grabbing device Dynamic range can cover the cabinet case of different depth, so that material is deposited in place deeper in cabinet case as much as possible, and Can material heap is high, without adjusting the position of container car artificially to cooperate the working range of the grabbing device, avoid The normal work of full-automatic handling material A GV is limited by container car size, in addition, due to the grabbing device and described stretching The extended end synchronizing moving of contracting conveying device, so that it is guaranteed that the job stability and operating accuracy of grabbing device;
(4) automatically handling material A GV is configured with mobile docking platform, and automatically loading and unloading material A GV can be according to reality Production needs to be moved to different harbours and carries out material transfer to different container cars, and full-automatic handling material A GV movement is flexible Property it is higher, to reduce setting of the enterprise to material handling equipment, save production cost, meanwhile, can be reduced enterprise and be used to park Bigger freedom degree is brought for corporate planning material handling region in the space of material handling equipment;
(5) automatically handling material A GV transports material using flexible conveying device, effectively reduces full-automatic handling The volume of material A GV and the site area of occupancy allow automatically to load and unload material A GV and apply in different usage scenarios, can Effectively expand the use scope of full-automatic handling material A GV.
Preferably, the grabbing device includes mobile foundation and robot device;The mobile foundation with it is described stretch it is defeated The extended end of device is sent to be fixedly connected, the mobile foundation includes car body, driving mechanism and driven wheel;The driving mechanism and institute Driven wheel setting is stated in the vehicle bottom, the driving mechanism is for driving the body movement, and the driven wheel is for branch Support the car body;The robot device is arranged on the mobile foundation.By the way that mobile base is arranged on the grabbing device Seat, it is ensured that the relatively described flexible conveying device of the grabbing device is provided with independent mobile device, so as to stablize in operation It is moved on face, and provides good support for robot device, improve the precision of the crawl material of the grabbing device.
Preferably, the flexible conveying device is equipped with several telescope supports, the width of the upper surface of several telescope supports Successively successively decrease, several telescope supports are sequentially stacked from big to small according to the width of upper surface, adjacent two telescope supports linkage; The outer end for being stacked in the telescope support of lower side is fixedly connected with the grabbing device.The flexible conveying device is set using above-mentioned Set mode, structure is simple, assemble it is convenient, meanwhile, when any telescope support damages, need to by the telescope support of damage into Row replacement, that is, can ensure that the normal use of the flexible conveying device, effectively shorten maintenance time and reduce maintenance cost.
Preferably, the extended end bottom of the flexible conveying device is equipped with driving mechanism and driven wheel;The driving mechanism For driving the stretching, extension end motion of the flexible conveying device, the driven wheel is used to support the stretching, extension of the flexible conveying device End;By the way that driving mechanism and driven wheel is arranged in the extended end bottom of the flexible conveying device, to be the flexible conveying The extended end of device provides support and power when moving on working face, on the one hand, can improve stretching for the flexible conveying device Stability of the Zhan Duan in stretching, extension and storage, to improve the reliability of the flexible conveying device and prolong the service life, separately On the one hand, when the extended end of the flexible conveying device is stretched over operating position, the driving mechanism and driven wheel can be used as institute The supporting point of the extended end of flexible conveying device is stated, so that the conveyor surface of the flexible conveying device be made to be in same position always It sets, cooperates convenient for the grabbing device and the flexible conveying device.
