Plastic pallet
Technical field
The present invention relates to logistics equipment manufacturing technology field, particularly a kind of plastic pallet relates more specifically to a kind of left-hand thread formula plastic pallet.
Background technology
Improving constantly of Along with people's living standard can not be satisfied present requirement to increasingly high, the traditional logistics that requires of modernized logistics.Be accompanied by the continuous development of domestic logistics industry; Various places and each large enterprises are all in the automated three-dimensional storehouse of building oneself; But because present some intrinsic defectives of plastic pallet; Make the conventional plastic pallet can not satisfy the demand in automated three-dimensional storehouse, become and hinder logistics modern one big obstacle, therefore be badly in need of improving.
The shortcoming of conventional plastic pallet is summed up as follows:
1, the conventional plastic pallet has multiple style, plurality of specifications at present, and double deck pallet, field word pallet, river word pallet, nine pin pallets etc. are for example arranged.The plastic pallet of every kind of style and every kind of specification all needs own specific mould, and the cost of each mould is all more than 1,000,000, and energy consumption is big, and efficient is low.
2, every type pallet all needs distinctive technology, can't unify, and causes the wasting of resources.The pallet welding process was processed about for example double deck pallet adopted, and processing technology is very complicated, and energy resource consumption is big.And pallets such as field word, river word, nine pin adopt disposable Shooting Technique to form, and die cost is high.
3, the conventional plastic pallet can't be discerned by infrared ray because the supporting leg bottom is not the plane, therefore is inappropriate for present automated three-dimensional storehouse.In addition, the color of conventional plastic pallet supporting leg and the color of upper plate are blueness, and this color also can't be discerned by infrared ray, therefore can not in the automated three-dimensional storehouse, turn round, and can only in the logistics of plane, use.
4, the different techniques standard all may be adopted in each automated three-dimensional storehouse at present; Therefore the height to plastic pallet all can have different requirement, and producer often need invest new mould if satisfy different requirement of client like this; Not only increase cost, also caused the waste of resource.
5, at present the conventional plastic pallet is embedded to steel bar in the plastic pallet during all in injection moulding when producing, but does not need the support of steel bar in the plurality of applications occasion, if therefore adopt the plastic pallet of band steel bar will certainly increase cost in this occasion.
6, because the RFID technology is often also adopted in the automated three-dimensional storehouse, and do not have corresponding position that this RFID is set in the conventional plastic pallet, therefore caused the conventional plastic pallet to use yet.
7, the surface of conventional plastic pallet is not anti-skidding, therefore usually can be on plastic pallet at fixedly one deck rubber or other materials as slipmat, but rubber tends to produce smell, is not suitable for some like products such as food, tobacco, grains.Equally, on the leg of plastic pallet, also there is same problem.
8, bar code often is attached on the outer wall of plastic pallet in the conventional plastic pallet, after the long-time use of pallet, tends to the bar code wearing and tearing are caused and can't discern.
9, the conventional plastic pallet, just needs all to change if certain part goes wrong often for the one injection moulding forms, and has caused the waste of resource, has also brought difficulty for past-sale service.In addition, the pallet of one injection moulding cost in transportation is also very big.
10, the upper plate of conventional plastic pallet is made up of a monoblock plastic flagstone, and permeability to air is poor, is inappropriate for the product that dryings such as carrying grain, medicinal material, tobacco is had relatively high expectations.
