Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, automatic access bin, comprises automatic material stock storehouse mechanism and material platform mechanism.
Described automatic material stock storehouse mechanism is used for depositing workpiece (omitting workpiece in figure), comprises storehouse frame, material stock storehouse 2-1, charging tray 3 and lifting unit;
Described storehouse frame is framed structure, comprises level and the storehouse frame upper head plate 2-12 be arranged in parallel up and down and storehouse frame bottom plate 2-14, is vertically fixed on some lifting guide pillar 2-9 (quantity is generally four) between storehouse frame upper head plate and storehouse frame bottom plate; Storehouse frame upper head plate is also manufactured with storehouse frame mouth 2-20, material stock storehouse in the turnover of this storehouse frame mouth vertical motion, can be deposited to coordinate robot or takes out workpiece.
In described material stock storehouse: rectangular frame is surrounded by the two pieces of flat boards arranged up and down (i.e. top board 2-1-1 and base plate 2-7) and some (normally four) post bar 2-1-2 of being vertically arranged in dull and stereotyped corner, the inside face (inner side of post bar) of the left and right sides, material stock storehouse arranges several bar shaped bearings 2-13 respectively, and these bar shaped bearings up and down between equidistant arrangement; The base plate in material stock storehouse is also positioned on lifting guide pillar by linear bearing 2-8, and thus material stock storehouse can be positioned in the frame of storehouse vertical motion;
Width and the material stock storehouse width of described charging tray adapt, and when charging tray pushes in material stock storehouse, the edge, the left and right sides of charging tray is respectively by the horizontal holding of bar shaped bearing of the right and left, and the quantity of bar shaped support is determined as required, are generally 5-20; And correspond to layout (horizontal projection overlaps) up and down between multiple charging trays in material stock storehouse and by the holding of bar shaped bearing; Each charging tray is shaped with some knock hole 3-1 for depositing workpiece, shape and the quantity of knock hole are determined according to workpiece (in Fig. 1, the shape of knock hole is for circular and quantity is 35).
Described lifting unit to be arranged on the frame of storehouse and for driving material stock storehouse vertical motion, comprises the motor 2-4 be fixed on the frame upper head plate of storehouse, for coordinating the reductor 2-3 of machine operation and being driven the band wheels that drive material stock qurush to fall by motor; In described band wheels, driving wheel 2-5 is rotatably positioned on the frame upper head plate of storehouse (in Fig. 4, display is fixed on the lower surface of upper head plate) and be connected with speed reducer output shaft, flower wheel 2-11 is rotatably positioned on the frame bottom plate of storehouse (in Fig. 4, display is fixed on the upper surface of bottom plate), and Timing Belt 2-10 is arranged on driving wheel and flower wheel and Timing Belt is fixed by stay 2-6 and material stock house bottom plate; The power of motor to be passed on driving wheel by reductor and to drive Timing Belt to rotate, thus drives material stock storehouse vertical lifting.
Charging tray can push in automatic material stock storehouse mechanism or from automatic material stock storehouse mechanism and pull out charging tray by described material platform mechanism, comprises mechanism support 1-8, for lifting the sensing chip 1-6 of the crotch 1-1 of charging tray, moving cell and detection charging tray position; Described mechanism support is fixed on the side left side of material stock storehouse (in the Fig. 4) of storehouse frame horizontal direction, and the bottom of mechanism support and storehouse frame bottom plate are connected and fixed and the height of material platform mount pad is about 2/1 to three/2nds of storehouse frame height;
Described crotch is arranged in the top of mechanism support, and crotch is shaped with a pair and can fastens the grab 1-11 on charging tray bottom sides edge with charging tray bottom sides along fit, crotch is pulled out charging tray by this grab or put into by charging tray and pushes material stock storehouse from material stock storehouse.
Described moving cell be also arranged in mechanism support top and for driving crotch translation and lifting, wherein: translation guide rod 1-5 is horizontally fixed on material platform mount pad, slide block 1-4 is positioned on translation guide rod slidably, front inlet casing 1-3 is for driving slide block along translation guide rod horizontal motion, and lift cylinder 1-2 to be fixed on slide block and for driving crotch vertical motion; The bearing of trend of described translation guide rod is parallel to the moving direction (in Fig. 4 shown in arrow A) that charging tray passes in and out from material stock storehouse, and the both sides of translation guide rod bearing of trend are also provided with and are parallel to translation guide rod and for two pieces of backplate 1-7 (spacing of backplate is slightly larger than the width of charging tray) on positioning material web edge.
The utility model controls the operation of above-mentioned each parts by artificial or signal switch (as travel switch).
Principle of work of the present utility model is:
1, some charging trays are placed with in material stock storehouse of the present utility model; After electric motor starting, material stock qurush is played specified altitude assignment (charging tray to be pulled out and crotch keep in the same horizontal line);
In material platform mechanism, front inlet casing promotes crotch near storehouse frame (grab of crotch stretches into the bottom waiting to pull out charging tray), then crotch is lifted certain altitude by lift cylinder, make the grab of crotch block charging tray bottom sides and rise charging tray (charging tray disengaging seat supports) along developing simultaneously, before last, inlet casing oppositely pulls crotch, make charging tray be drawn out storehouse frame and place (charging tray arrival assigned address on mechanism support, namely sensing chip 1-6 sends signal, front inlet casing stop motion);
2, next step operation robot can from charging tray grabbing workpiece or workpiece is put into charging tray; After workpiece completes and picks and places, charging tray pushes on the bearing in material stock storehouse by front inlet casing again, then crotch is fallen the grab disengaging charging tray bottom sides edge that certain altitude makes crotch by lift cylinder, and last front inlet casing pulls out crotch and material stock storehouse drops to initial position.
