Figure 10 represents the enlarged drawing of an end of horizontal stripe 4.The structure of horizontal stripe 4 comprises: as the par 41 of workpiece mounting surface, a pair of side wall portion 42 and a pair of flange 43 that extends laterally from each side wall portion 42 that is formed on 41 both sides, par with formation cross section コ word shape.Make horizontal stripe 4 according to above-mentioned shape and further improve beam strength when using flat board members, so horizontal stripe 4 can use the thinner material of thickness of slab, thereby can realize the lighting of horizontal stripe 4.Be fixed with a plurality of mounting pins 44 that are used for supporting glass plate S above the par 41.Mounting pin 44 is to be formed by higher polyetheretherketone of abrasion test (PEEK (registered trade mark (RTM))) or ultra-high molecular weight polyethylene (UPE) etc., even carry glass substrate S repeatedly, does not also produce the dust that brings because of wearing and tearing substantially, thereby can not pollute glass substrate S.At the two ends of par 41 and dispose the support 14b of support unit 14 in the コ word shape of cross section, both are fixed by not shown rivet.Like this, par 41 is supported on housing 2 by support unit 14.
In above-mentioned pallet 1, the top of the rake 13 of framework part 2a, the 2b of housing 2 and inboard par 12 be as surrounding parts and play a role, its be used to cover horizontal stripe 4 par 41 around.Particularly, surrounding parts is the wall that is higher than the par 41 of horizontal stripe 4.Therefore, can be from the peripheral part of outside cover glass substrate S.In addition, though for example because of device promptly stop glass substrate S is moved, glass substrate S also is difficult to fly out from pallet 1, though perhaps just in case under the damaged situation fragment also be difficult to disperse to around structure.
(4) structure of resin mass
The structure and the configuration of (5) first resin mass and second resin mass
(a) common structure
Fig. 6 (a) is the birds-eye view of the first resin mass 8A, and Fig. 6 (b) is the front view of the first resin mass 8A, and Fig. 6 (c) is the upward view of the first resin mass 8A, and Fig. 6 (d) is the lateral plan of the first resin mass 8A.Fig. 8 (a) is the front view of the second resin mass 8B, and Fig. 8 (b) is the upward view of the second resin mass 8B, and Fig. 8 (c) is the lateral plan of the second resin mass 8B.
At first, will the common structure of the first resin mass 8A and the second resin mass 8B be described.Resin mass 8A, 8B mainly have the main part 20 of approximate cuboid.Main part 20 is longer at the left and right directions of figure.According to the height that mode that height H 1 (referring to Fig. 5) equates forms main part 20 that holds that is used for holding safely a substrate S.Be provided with protuberance 21 above the main part 20.Protuberance 21 is formed conical shaped or circular cone is trapezoidal.
The both sides of main part 20 are extended with the portion of being supported 23, be supported portion 23 and be used for tray stack, take the contact part that supports when stacked apart.Be supported and be through with housing mounting hole 24 in the portion 23, housing mounting hole 24 is used for resin mass 8 is fixed on framework part 2a, 2b, and resin mass 8A, 8B are fixed on the housing 2 by the screw-nut 19 (Figure 13) or the rivet of penetrating mounting holes 24.Fig. 3 and Fig. 4 are expression resin mass 8A, 8B are fixed on the state on framework part 2a, the 2b by screw-nut (Figure 13) or rivet block diagrams.Resin mass 8A, 8B are according to the following butt of the par, the outside 11 that is supported the top of portion 23 and framework part 2a, 2b, and the top of protuberance 21 and main part 20 is fixed from piece portion mounting hole 17 outstanding states.The par, the outside 11 that is higher than framework part 2a, 2b above the main part 20 of resin mass 8A, 8B.In addition, following (protuberance 25 described later following) of main part 20 be lower than par 11, the outside below.
By such configuration, when at above-below direction during with multilayer mode stacked tray 1, the main part 20 of resin mass 8A, the 8B of each pallet 1 top and below be in contact with one another, so pallet 1 is a spacing and stacked with the height of the main part 20 of resin mass 8A, 8B.
As mentioned above, being configured to of the pallet 1 of present embodiment: form respectively as fixing after resin mass 8A, the 8B of contact part and the housing 2 with different materials.Thus, can only be suitable for using and to suppress the material that dust produces, therefore easily process, form contact part at contact part.On the other hand, the other parts of housing 2 do not contact with other pallet 1 and equipment etc. substantially, therefore are suitable for using the material of more paying attention to intensity compared with the inhibition of dust, can enlarge the degree of freedom of the material of selecting housing 2.
(b) different structure
Then, will the not isostructure of the first resin mass 8A and the second resin mass 8B be described.As shown in Figure 6, the main part 20 of the first resin mass 8A below be provided with recess 22.Recess 22 is to be formed between the protuberance 25 that a pair of long side direction at main part 20 extends and the groove of its both ends open.Recess 22 has and top protuberance 21 cooresponding cross sectional shapes.Fig. 7 is the lateral plan of the state that engages mutually of two first resin mass 8A of expression.Under above-mentioned state, the first resin mass 8A can relatively move on the long side direction of main part 20.In addition, the first resin mass 8A can relatively rotate around the center shaft of protuberance 21.
As shown in Figure 8, the main part 20 of the second resin mass 8B below be provided with recess 26.Recess 26 is formed at a pair of between the protuberance 27 that separates on the long side direction of main part 20, and open on the short side direction of main part 20.Fig. 9 is the partial front elevation view of the state that engages mutually of two second resin mass 8B of expression.Under above-mentioned state, protuberance 21 is guaranteed the gap for recess about 26, front and back.In a word, though second resin mass 8B supporting is positioned at the weight of the pallet 1 of upside, yet pallet 1 is not positioned each other.
(c) configuration
Below, will the configuration of the first resin mass 8A and the second resin mass 8B be described.As shown in Figure 2, resin mass 8A, 8B are arranged on last each three place of each framework part 2a, 2b and add up to 12 places.
The first resin mass 8A is disposed at A position, B position, three places, C position of Fig. 2.A position, B position are the both end sides of the minor face framework part 2b of figure downside.The C position is the minor face parts 2b side away from the figure downside on the long margin frame body spare 2a in figure left side.Like this, the first resin mass 8A of A position and first 8A of B position are configured on the identical minor face framework part 2b, recess 22 towards also identical.Relative to this, the first resin mass 8A of C position is configured on the straight line of first 8A of the first resin mass 8A that connects the A position and B position, in addition recess 22 towards also with both recess 22 towards different.Remaining nine place disposes the second resin mass 8B.
According to above-described structure, can under parts precision and the also impregnable situation of assembly precision deviation, carry out stacked.This is external also to limit the first resin mass 8A moving each other with minimal gap after stacked.Therefore, under stacked state,, also the accumulative total of pallet 1 dislocation can be controlled at irreducible minimum even in conveying, adopt under the situation of emergency braking.
In addition, bigger in the size of pallet 1, and do not obtain fully for lighting under the situation of intensity of housing 2, the second resin mass 8B of the position D of Fig. 2 also can be replaced into the first resin mass 8A.The D position is the minor face framework part 2b side near the figure downside on the long margin frame body spare 2a in figure left side.In these cases, can limit change in location between the resin mass 8 that the elastic deformation because of housing brings effectively.
