Tray with shovel arm cavities in two directions

Abstract

The invention discloses a tray with shovel arm cavities in two directions, and belongs to the technical field of stacking and packaging. The tray comprises a tray body, the upward surface of the tray body forms a goods stacking tabletop, and the downward surface of the tray body forms a tray body supporting surface. The left side, the right side and the center of the tray body supporting surface form tray body supporting mechanisms respectively. The tray is characterized in that each tray body supporting mechanism comprises three tray body supporting feet, wherein every two adjacent tray body supporting feet are connected through a tray body supporting foot connecting rib, and the tray body supporting foot connecting ribs are provided with the transverse shovel arm cavities; tray body reinforcing bosses are arranged on the tray body supporting surface, and tray body reinforcing parts are embedded in tray body reinforcing boss cavities of the tray body reinforcing bosses. Interference influences are avoided, and the requirement that a shovel transportation device can select the longitudinal shovel arm cavities and the transverse shovel arm cavities as needed according to the space conditions of an operation place can be met. Materials are saved, and the weight is reduced. The strength of the tray is improved, and the tray is convenient to clean, simpler in structure and low in cost.

Description

technical field [0001] The invention belongs to the technical field of stacking and packaging, and in particular relates to a pallet with bidirectional shovel arm cavities. Background technique [0002] The aforementioned pallets are also called pallets, which are widely used in warehousing and logistics industries. For the concept and use of pallets, please refer to column 0002 of the specification of the invention patent authorization announcement number CN102009774B (the patent was proposed by the applicant). Compared with the Chinese patent authorization announcement number CN2536528Y (artificial skid with improved structure), CN2536529Y (artificial skid with improved structure), CN2536530Y (artificial skid with improved structure), CN2747171Y (packaging pallet) and authorized announcement number CN2887765Y (packaging As far as pallets are concerned, CN102009774B objectively has the technical effects described in the technical effect column of its description (see paragr...

Problems solved by technology

[0004] However, the above-mentioned CN103552737B still has the following technical problems that need to be remedied: First, because the shovel arm cavity is a one-way shovel arm cavity, a pair of spaced sides is formed only at the bottom of the pallet body towards the floor side when the pallet body is in use. The shovel arm cavity penetrates from left to right, so there is pickiness about the shoveling direction. For example, in the state of stacking in storage, when there are follow-up When other goods are stacked, and the space between other goods and the left and right openings of the shovel arm cavity of the pallet body is too small to be driven in by a shoveling device such as a forklift, it can only be removed first. other goods, thereby affecting the transfer efficiency of the target goods; second, since a pair of shovel arm cavities are formed between two adjacent pallet support feet, the pallet support feet must be continuous from the left side of the pallet body to the right. As a result, on the one hand, the material consumption of building the pallet support feet increases, and the pallet body becomes too bulky; on the other hand, the pallet support feet only play the role of supporting goods and Separate the monotonic effect of the shovel arm cavity; thirdly, when a pair of shovel arms of the scraper device are inserted into and lifted the pallet body loaded with goods in the corresponding pair of shovel arm cavities on the pallet body, due to stress concentration, it tends to There is an unwanted but objectively unavoidable arching trend, that is, the pallet body appears like a bread-like trend in food, especially when the quality of the goods stacked on the pallet body is large, this trend is particularly obvious. The arc arch phenomenon is a taboo in the process of cargo transfer, because a pair of shovel arms are slightly out of balance, and the cargo will jump out from the side of the pallet body, resulting in damage and even accidents; Fourth, because the pallet body is in use The side facing upwards is formed with many upper bearing longitudinal cavities, upper bearing transverse cavities, upper bearing lateral reinforcement cavities, upper bearing longitudinal reinforcement cavities, etc., so it is easy to accumulate dust and it is difficult to clean It is clean; Fifth, due to the relatively complex overall structure of the tray body, the mold structure for blow molding is also correspondingly complicated and expensive, and because the high mold price will eventually be passed on to the tray body, the tray body has lose economical cheap
