Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a pallet with a non-slip device, and more specifically, a pallet body formed by injection molding of synthetic resin,
By the injection molding, a non-slip elastic member embedded in the pallet body in a partially projecting state is provided, and the projecting portion of the non-slip elastic member partially projecting from the deck surface or the fork surface of the pallet body is , A pallet with anti-skid device adapted to stop the sliding of an object located in contact with the deck surface side or the fork surface side.

[Conventional technology]

In such a pallet with an anti-slip tool, the deck surface of the pallet body, the fork surface, or the protruding portion of the elastic member for non-slip that partially projects is located on the deck surface side (specifically, on the deck surface). To prevent slippage of objects to be transported, etc.) and slippage of objects located on the fork surface side (specifically, forks of forklifts that are inserted into the fork holes and pressed against the fork surface) Will be fulfilled. In addition, the non-slip elastic member,
An elastic material such as rubber that can elastically deform when pressure is applied to increase the friction coefficient of the contact surface is selected as the material so that the protruding portion can sufficiently perform the above-mentioned function.

By the way, if the non-slip elastic member falls off from the pallet body while the pallet is in use, the function cannot be fulfilled. Therefore, conventionally, in order to prevent the slip-out, the following measures have been taken when performing the injection molding.

That is, the injection molding conditions are set so that the anti-slip elastic member and the pallet body are heat-sealed, and
As shown in the figure, a plurality of irregularities (31) are formed in an annular shape on the outer peripheral surface of the anti-slip elastic member (30) to increase the contact area between the anti-slip elastic member (30) and the pallet body (10). The two (10) and (30) are heat-sealed together to improve the bonding strength of the both (10) and (30) (see Japanese Patent Laid-Open No. 52-123044).

[Problems to be solved by the device]

When the pallet body is injection-molded while embedding the anti-slip elastic member, the pallet body is cooled from the heated and fluidized state. Then, at the time of cooling, the pallet body is pulled and shrink-molded, but its deformation is caused by various causes (for example, the influence of the reinforcing member embedded in the pallet body) around the anti-slip elastic member. Does not always occur uniformly, and usually contracts and deforms in a distorted state. In other words, when the mounting hole (which may be a hole) of the anti-slip elastic member in the pallet body is viewed from the pallet thickness direction, the mounting hole generally shrinks as the pallet body shrinks, but a part of the mounting hole It may swell. Therefore, a gap tends to be formed between both the pallet body and the slip stopper. Therefore, even if the various measures described above are taken to strongly heat-bond the two, the force for forming the gap is based on the distorted shrinkage deformation of the pallet body, and the heat-welding force between the two is And a slight gap is formed between the two. Then, when such a gap is formed, moisture that adversely affects the durability of the pallet and the like enters the gap. Further, if the gap is formed to be extremely large, the anti-slip elastic member may fall out.

The present invention was created with attention paid to such circumstances, and an object thereof is to provide a means capable of solving the above-mentioned problems.

[Means for Solving the Problems]

A characteristic structure of a pallet with anti-slip according to the present invention comprises a pallet body formed by injection molding of synthetic resin, and an anti-slip elastic member embedded in the pallet body in a partially protruding state by the injection molding. A slip portion in which a protruding portion of the anti-slip elastic member that partially projects from the deck surface or the fork surface of the pallet body serves to stop the non-slip of an object located on the deck surface side or the fork surface side. A pallet with a stopper, wherein the non-slip elastic member has an extending portion extending from a main body portion thereof in a direction orthogonal to a pallet thickness direction, and the inside of the extending portion is formed by injection molding. In this case, the operation and effect are as follows due to the formation of the convex portion which is recessed in the pallet thickness direction for allowing the filling of the synthetic resin.

[Action]

The anti-skid pallet of the present invention is such that, in the injection molding process of the main body, the synthetic resin forming the pallet main body is filled in the recess formed in the non-slip elastic member, and the filled synthetic resin portion is filled. Engages with the extending portion of the anti-slip elastic member, and the pallet body and the anti-slip elastic member are coupled via the engaging portion.

As a result, even if the pallet body is cooled from the heated and fluidized state in the injection molding process, and even if distorted contraction deformation of the pallet body occurs at the time of cooling, the anti-slip elastic member coupled to the pallet body through the engaging portion The member elastically deforms,
The non-slip elastic member remains in engagement with the pallet body, and the gap is not formed.

[Effect of device]

As described above, according to the present invention, since a gap that allows the entry of moisture that adversely affects the durability of the pallet is not formed, the quality such as the durability of the pallet is improved. In addition, the problem of slipping off of the slip-resistant elastic member that occurs when the gap is extremely large is solved.
