Abstract

A tray having a vertically stacking unit is provided to receive uniform load all the time by placing a support sill on the upside of a partition by a recessed groove. A tray(10) having a vertically stacking unit comprises four sides by forming cells(11) of predetermined depth connected by partitions. The partitions forming each cell has an inner space at the back side by an upside(13). A recessed groove(14) is formed on one surface of the inner side of each partition. The recessed groove has an inclined surface(16) widened from the upper side to the lower side, viewed from the back side. A support sill(15) having a predetermined surface is protruded on a part where the inner space is formed. The support sill is placed on the upside of the partition of the other tray.

The present invention relates to a tray that can be moved and used in a state in which a small article is loaded, and is particularly used in an industrial automation process, and to provide ease of operation during storage or use in a state where parts are stored.

Currently used trays are stored in a large amount of various kinds of parts in an automated process, and are used individually by being transported.

Therefore, for continuous operation, the trays must be used by separating the sheets one by one in a multi-layered state, and there should be no deformation of the trays by the pressing force transmitted to the trays by picking up and transporting the parts accommodated in these trays by robots, It should be used in place.

However, the conventional trays are formed by forming a plurality of compartments by partition walls with spaces in which most parts can be accommodated, as shown in FIGS. 9 and 12, and forming them by attaching them to one sheet by vacuum molding. In this state, even though each compartment of the stacked trays is stacked, the compartments stored in each compartment are stored and used in an automated process so that the bottom surface of the lower compartment is not allowed to enter.

However, this lamination structure is easy to store, but when it is used to separate each tray in the upper layer and the lower layer in the state of use, a separate work process that needs to hold the upper layer and the lower layer for separation is required, especially for long time storage. When it is, there is a disadvantage that each compartment is stacked deep because it is not easily separated in the automated process.

Therefore, in order to improve this, as shown in FIGS. 10 and 13, the cells formed in the trays of the upper layer and the lower layer may be manufactured in different forms or may be manufactured in the same manner, and then laminated by rotating the lamination state by 180 degrees. It is convenient to use because the spaces stacked up and down are not inserted into each other. However, in this case, there are many problems in the device implementation that the machine should be rotated by 180 degrees when used for work. .

Accordingly, in the present invention, in order to solve such a problem, the inner side of the partition wall of each compartment having a certain depth is formed in the inner groove of the form that goes from the top to the bottom to open the support jaw at the outside of the partition wall This protruding projection allows the support jaw to be placed on the upper surface of the partition walls constituting each compartment, so that even when stacked in the same form, the upper and lower compartments can not be inserted and can be accurately stacked up and down.

In addition, the laminated structure can withstand the load even by a strong force pressed up and down to improve the working environment.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figs. 1 to 8, the tray 10 of the present invention heats one sheet of plastic sheet having a constant thickness to be heated by a vacuum or a press in a sintered state, and the surface is shown in Figs. 5 and 6. As shown in FIG. 5, the partitions are formed by quadrilaterals to form respective compartments 11 connected to each other having a predetermined depth by the partition walls 12 and the partition walls 12a. 12 and 12a are formed by the upper surface 13, respectively, as shown in FIGS. 7 and 8, and the inner space 17 is formed on the rear surface thereof, as shown in FIGS. 5 and 6, respectively. Inner grooves 14 are formed on one inner side surface of each of the partition walls 12a constituting the partition wall, and the inner grooves 14 are open from the upper side to the lower side as shown in FIGS. 7 and 8. A base having an inclined surface 16 and having a constant surface as a portion where the inner space 17 is formed. A configuration formed to protrude to 15, which is to be put on the upper surface 13 of the partition wall 12 as shown in Fig. 5 and 6, the base jaw (15).

Therefore, the upper surface 13 of the partitions 12 and 12a constituting each compartment 11 has no groove and has only a constant upper surface 13, so that the supporting jaw 15 formed at the bottom thereof is the upper surface of the partition 12. Being placed in (13) is able to withstand a constant load at all times and each compartment 11 is not inserted into each other to facilitate the separation for use in a stacked state.

At this time, the supporting jaw 15 is formed on all sides of the partition wall 12 constituting each compartment 11 and each position is formed in a position (symmetrical direction) that is symmetrical to the tray 10 is the upper layer and Even when pressing any part in a state of being stacked in a lower layer, deformation by pressing on the tray 10 does not occur, and a uniform load is always uniformly received.

Therefore, it is easy to be separated by overlapping of compartments when stacking the upper layer and the lower layer without deformation of the compartment, and the supporting jaw by the indentation groove is placed on the undamaged upper surface of the bulkhead so that it is always subjected to uniform load. The tray's function will be excellent.
