Description
Technical field
The invention belongs to logistic storage systems technology field, particularly one is used Special Automatic floor truck Transport cargo rack, realizes the shelf warehousing system of unbundled sorting by Transport cargo rack.
Background technology
Along with social progress, logistlcs technology is deep into all trades and professions.Under the identical prerequisite of storage content, can divide according to the not equal factor of the difference of the difference of construction style, storage form and article move mode the multiple different storage pattern that is combined into.The first kind is stereo garage, and can be divided into stacking machine for tunnel with track formula stereo garage is that automatic stereowarehouse, high-order three-way fork truck stereo garage are VNA-Very Narrow Aisle narrow passage formula, high-order bogie type fork truck stereo garage, board-like stereo garage etc. shuttles back and forth.Equations of The Second Kind is multi-storey building storehouse, can be divided into Pallet for forklift shelf storehouse, two-layer pallet and stack storehouse, stacking etc. on the spot without shelf pallet-free storehouse or smallclothes.The 3rd class is low layer plane library, be called for short flat storehouse, can be divided into the flat storehouse of Pallet for forklift shelf, two-layer pallet stacks storehouse, is that hangar, steel wire elevator secret Ji Ku etc. are carried in the intensive storehouse of drive-in, the intensive storehouse of the through drive-through of being, portable intensive storehouse, the intensive storehouse of gravity type boat davit, Conveyorized intensive storehouse, low layer piler without shelf pallet-free storehouse (moistureproof backing plate, shield, smallclothes are stacking on the spot), the formula of sailing into.
No matter which kind of mode storage technique adopts, at the flow process end of article, that is to say in retailing logistics distribution center, in the today that generally adopts electronic display tag auxiliary sorting, although use the various zero picking methods of tearing open, but can be summed up as generally two kinds: one is that order is not chosen, be commonly called as the fruit formula of plucking; Another kind is that commodity do not gather selection, is commonly called as sowing type.
Plucking fruit formula selection method, is for every a order or each client, and picking personnel or equipment are touring in each goods storage space, and required goods is taken out, and likeness in form is plucked fruit.Be characterized in that everyone only processes a order at every turn, or a client.After round Realization mechanical automation, the work flow of plucking the selection of fruit formula is as follows: first from warehouse district to tearing zero selection district deliver goods open, and shelf are put in goods yard one by one; Then Turnover Box is moved along sorting conveyor line, sorting personnel picking from shelf, puts into Turnover Box; Finally the goods that packs Turnover Box into is checked according to kind, quantity etc., sometimes also needed to change cargo in case.
Sowing type method of distributing, is many parts of orders, or multiple clients' enquiry requirements set becomes a collection of, the quantity of every kind of commodity is wherein gathered respectively, then kind is carried out distribution of goods to all clients one by one, and likeness in form sowing, is called by " commodity do not gather point broadcast ".The work flow of sowing type sorting: first gather picking: from warehouse district, this ripple time required goods is all sorted out, delivered to unbundled sorting district, be put into one by one on sorting line; Then distribution of goods along the line, containing checking vanning, treats that a point container moves along conveyor line, and sorting personnel picking from case, puts into shelf-box.Intermittence is checked, is cased; Be finally consolidating the load as ready, deliver to shipping space checking the complete container of vanning, wait transports.
Tear the feature of zero selection mode open for two kinds as can be seen from the above description:
Manual mode is plucked fruit formula selection method: if goods required on order is taken out, picking personnel must be touring in each goods storage space, need to the go the rounds walking operating distance in thousands of goods yards of picking personnel, normally hundreds of rice length of this distance, this mode has an obvious advantage, be warehouse district and selection area overlapping, there is no obvious boundary;
Travel line formula is plucked fruit formula selection method: after adopting automation travel line, the work efficiency of plucking the selection of fruit formula is obviously promoted comprehensively, but the thing followed is: the cost of sorting delivery system significantly improves; Use and maintenance cost significantly improves; The complexity of system improves, reliability reduction etc.;
When the kind number of tearing zero selection open is less than 300, and order customer quantity is huge, while exceeding 1,000, is just applicable to very much using and plucks really formula sorting;
Order response time is shorter is the advantage of plucking fruit formula;
When tearing the kind of zero selection open when more, for example be greater than 1,000, corresponding identical sorting ability, pluck the shelf of fruit formula sorting system and travel line length, floor area much larger than sowing type system, therefore how a lot of cost and operating personal quantity is also, in other words,, if take same site area, the sorting ability of sowing type system can be more much larger than plucking fruit formula;
Tear on a large scale zero selection open for order kind and quantity are all many, sowing type sorting has many-sided advantage than plucking fruit formula, now should be take sowing type as key operation flow process, and be suitably aided with and pluck really formula flow process;
Modern logistics market is more and more higher to ageing requirement, increasing goods does not often enter just directly sorting shipment of warehouse district, be called " passing through type " logistics, plucking fruit formula sorting mode must be placed on goods to tear open on zero shelf and could sort shipment, therefore be difficult to support " passing through type " logistics, analyzed from mode of operation, " passing through type " logistics can be finely supported in sowing type sorting, such as fresh food sortings etc., are also convenient to DISTRIBUTION CENTRE and realize the quick replacement of line of business;
For commercial distribution, sowing type system easily realizes the progressively expansion of scale, is convenient to realize the upgrading from low to high, from handwork to automation, more can adapt to enterprise's progressively development from small to large;
Pluck fruit formula sorting technology and be directly derived from the most original shelf picking mode, simple to operate, technology maturation, because being processes respectively every part of order, the control and management ratio of flow process is easier to;
Because sowing type sorting need to be processed many orders simultaneously, between order, there are various difference, as kind overlap ratio, packaging volume, quantity, physical condition etc., the integrated operation difficulty that therefore sorts flow process is greater than the fruit formula of plucking;
The work mistake of plucking the sorting of fruit formula only affects a order conventionally, and what sowing type affected is a collection of order, therefore uses sowing type sorting higher to the requirement of workflow management, and management information system, personnel's operation, rules and regulations are had to higher requirement;
As seen through the above analysis, two kinds of zero selection modes of tearing open respectively have merits and faults.
Summary of the invention
For solving in existing logistics operation, when fruit formula selection method is plucked in employing, picking personnel labour cost is high, and the high problem of handling cost while adopting sowing type method of distributing the invention provides a kind of small-scaled shelf warehousing system based on automatic transporting dolly, its technical scheme is as follows:
