Automatic pallet delivering device for palletizing system
The utility model relates to a kind of goods automatic pallet delivering device for palletizing system of lifting automatically that is used for.
Carry out goods, workpiece when lifting automatically at harbour, warehouse, manufacturing line, will use pallet in its palletizing system, pallet then needs to provide automatically by setup program.The pallet apparatus that supplies in the past adopts hydraulic pressure, motorized motions to add mechanisms such as upper screw rod transmission, gear transmission, chain-driving and rack-and-gear transmission and carry out the lifting or the decline of pallet, stop place after the rotary type latch of employing air cylinder driven is raised pallet is carried out spacing, above driving device structure is complicated, installation and maintenance inconvenience, input expense height, and hydraulic efficiency gear has pollution, power consumption height during the electric device Fraquent start unavoidably, the rotary type latch is stuck sometimes, and flexibility and reliability is not good enough.
The utility model content
The technical problems to be solved in the utility model is to overcome existing weak point for pallet apparatus, and a kind of simple in structure, convenient for installation and maintenance, less investment is provided, and helps the automatic pallet delivering device for palletizing system of environmental protection and energy saving, use flexibility and reliability.
The technical solution of the utility model is: automatic pallet delivering device for palletizing system comprises pallet storehouse, lifting mechanism, latch detent mechanism and control part, to be described lifting mechanisms be made of 1～4 double stroke cylinder that is located at pallet bottom of the reservior portion and lifting guiding mechanism improvements, described latch detent mechanism constitutes by being located at many horizontal latches on the symmetry side, pallet storehouse and driving cylinder, each latch line of centers is located in the same horizontal plane, and above-mentioned double stroke cylinder is connected with described control part with the driving cylinder.
Further scheme is: described double stroke cylinder is to have the single cylinder of two kinds of strokes or the combined cylinders that is in series by two one-stroke cylinders; Described horizontal latch is 3～4, and latch one end has diameter clearance with driving cylinder junction.
The pallet apparatus that supplies of the present utility model adopts double stroke cylinder under the guiding of riser guide, realize the lifting of pallet, adopt one or many double stroke cylinders according to pallet specification and weight different, whole device is only used pneumatic drive mechanism, simple in structure, be convenient to installation and maintenance, less investment, many power consumptions when avoiding Fraquent start in oil pollution in the hydraulic-driven and the motorized motions in service meet the energy-conserving and environment-protective requirement.Horizontal latch moving linearly of while, there is diameter clearance its junction, end, avoids the junction to produce moment of deflection, can be not stuck, flexible movements are reliable.Latch is preferably 4 symmetries and installs, and also can a side adorn two, and opposite side is adorned one, and each latch line of centers is contour, guarantees stress equalization, and pallet is steady.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Further specify the utility model architectural feature and working process below by embodiment.
Referring to accompanying drawing, pallet storehouse 5 is a rectangular frame, interior tray group 6, and pallet is packed into from the rectangular frame top, by oblique guiding, the pallet group is stacked neatly, and pallet group each pallet from the bottom up is decided to be P1, P2, P3 successively ...Pallet bottom of the reservior portion is provided with the double stroke cylinder 1 of 2 symmetrical distributions, every double stroke cylinder 1 is the combined cylinders that is in series by two one-stroke cylinder 1-1 and 1-2, there is lifting guiding mechanism 2 the cylinder side, the driving cylinder 4 of respectively establishing 2 horizontal latches 3 and matching on one group of symmetry side in pallet storehouse, each latch line of centers is located in the same horizontal plane, there is diameter clearance latch one end and cylinder junction, and above-mentioned double stroke cylinder and driving cylinder carry out programming control by control part.
The confession pallet apparatus of this enforcement is when initial condition, and latch withdraws from, and cylinder 1-1 and 1-2 all are in the retraction state, and all tray supportings are on feedway 7.Working process is: the first step, realize the separation of pallet P1 and send.Cylinder 1-2 is stretched out, with pallet group jack-up, allow latch insert the gap of pallet P2, the cylinder 1-2 that withdraws again is placed on pallet P1 on the feedway, and all the other pallets are held by latch, and this moment, P1 saw off smoothly; In second step, realize the separation of pallet P2 and send.Cylinder 1-1 and 1-2 are stretched out simultaneously,, allow pallet P2 exceed latch, withdraw from latch pallet group jack-up, the cylinder 1-1 that withdraws again, the gap that allows latch insert pallet P3, condensation cylinder 1-2 again is put into pallet P2 on the feedway and sees off smoothly.Repeat the action in second step, just the pallet in the pallet storehouse can be seen off one by one.Above working process after each action puts in place, is sent signal by sensor, controls this device by setup program by control part again and carries out automatically.
