Description

Pallet

Technical field

The invention belongs to stacking and packing material technical field, be specifically related to a kind of pallet.

Background technology

Pallet also claims pallet, very extensive in storage and the application of logistic industry, can be proposed by the applicant referring to this patent of invention patent mandate notification number CN102009774B(about concept and the purposes of pallet) specification sheets the 0002nd hurdle.With respect to the structure improved artificial skid of Chinese patent Granted publication CN2536528Y(), the artificial skid of CN2536529Y(structural development), the structure improved artificial skid of CN2536530Y(), CN2747171Y(Underpan for package) and Granted publication CN2887765Y(Underpan for package) for, CN102009774B objectively has the technique effect (specifically referring to specification sheets the 0017th hurdle) described in the technique effect hurdle of its specification sheets.

But, in view of aforementioned CN102009774B has shortcoming, therefore " pallet " (patent application being proposed by the applicant) of being recommended by Granted publication CN102407967B done to make up, specifically can be referring to the 1st to the 3rd page the 3rd section of the specification sheets of this CN102407967B.

But, although aforementioned CN102407967B has the flexible selection requirement of shovel arm insertion the first shovel arm slot or the second shovel arm slot that can meet forklift, and there is the labour intensity that alleviates workman's handling and the technique effect that improves the transfer efficiency of goods, but still there is following shortcoming: the one, due to first, the shape of cross section of the second shovel arm slot all shows as n shape (inserting at the shovel arm in by forklift under the state of the first shovel arm slot or the second shovel arm slot), that is to say due to first, the second shovel arm slot is uncovered, therefore under stacking or title piling state, in the time that the shovel arm (industry also claims teeth) of forklift inserts from the shovel arm slot of a superposed pallet, there is the anxiety that the goods on the pallet of bottom exerts an influence to stacking, for example, in the time that the shovel arm of forklift touches the goods of stacking on the pallet of bottom and likely undermine goods, the 2nd, because stability in the time that shovel arm holds up the pallet that is loaded with goods is difficult to ensure, therefore can only be made up by the gait of march that slows down forklift, but so disposal options can affect operating efficiency, the 3rd, due to the structure relative complex of pallet, therefore cause that Mould Machining difficulty is large and cost is high, the 4th, owing to separating the comparatively fragility of wall body of first, second shovel arm slot, therefore when the shovel arm of forklift is when together with stacking, the goods on pallet shifts pallet under lifting state, there is the anxiety of not wishing the amount of deflection occurring and/or tearing situation in first, second shovel arm slot position of pallet, the 5th, as aforementioned, because shovel arm stability in the time lifting the pallet that is loaded with goods is difficult to ensure, therefore suitable use has the forklift (industry claims multiple tooth fork truck) of multiple shovel arms, there is the forklift (bidentate fork truck) of a pair of shovel arm and be not suitable for adopting, so caused the fastidious property to forklift, reason is fairly obvious, because, if when using double-arm forklift and a pair of shovel arm of forklift being corresponded respectively to the left side of pallet and the first shovel arm slot on right side or the second shovel arm slot insertion lifting pallet (goods is housed), the central region of pallet very easily produces amount of deflection so, is affected the service life of pallet.Otherwise, if a pair of shovel arm of forklift is inserted while being positioned at two first shovel arm slots at pallet position placed in the middle or the second shovel arm slot lifting pallet, so because stability cannot ensure the risk that exists pallet to roll together with goods.

In addition, if ignore the fund input factor of pallet production manufacturer to equipment variations in order effectively to eliminate the shortcoming of aforementioned CN102407967B, can cause so undoubtedly the scrap build cost of the production firm of the pallet of producing CN102407967B structure to increase, therefore how rational modification support holder structure with alleviate that between production firm's scrap build cost, to find rational equilibrium point same be a key factor overlooking either of the two, in brief, the improvement of support holder structure must take into account the interests of the manufacturer that produces pallet and the continuity that equipment uses.
