, carry lamellar article the article distortion in can preventing to carry by more than being put into independent container.But such conveying form exists in the problem that occupies very big keeping space when temporarily taking care of in the way of carrying.And, wanting to put together be transplanted on other local time, also there is the problem of taking time and energy very much.
Therefore, considering can lamellar article placed apart, and can be with the container scheme of stacked container mutually in interim keeping or when being transplanted on other place and going.But there is in the container accumulation dust in such container or itself produces the such problem of article that dust pollution is placed when stacked.And, have that whole weight becomes heavy when stacked, the inconvenient such problem of keeping or carrying.
In order to overcome such problem, considered once to accommodate the scheme of the box of many article for the transporting thin plate-like articles.But, when between device, carrying, be necessary that in the entrance of each device that drops into article the special use that is used for taking out lamellar article in box and drops into being set drops into manipulator with such box.
Thin-type display devices etc. are in most cases made in the clean room, are necessary to carry in the clean room.For glass substrate being dropped in each manufacturing installation in the clean room, need few produce dust and can unmanned running with the corresponding input manipulator in clean room.Such manipulator price is very high, and the acquisition cost of causing delivery system increases.
And thin-type display device sharply maximizes in recent years, and 1 of the weight of the employed large-size glass substrate of read out instrument has tens kilograms.And the box of accommodating large-size glass substrate needs quite high intensity, so the weight of box itself increases.Generally speaking, use during conveying and once accommodate 20 pieces of box-shaped boxes of carrying together to 40 pieces of glass substrates, but the box gross weight that glass substrate is housed is sometimes above 1 ton.
Not only price is higher to be used for dropping into the manipulator of glass substrate of maximization, Heavy Weight, and in order to carry the box of about 1 ton of total weight to need hoisting crane between operation and the operation.Owing to need these equipment, therefore use the delivery system of box to have along with articles conveyed maximization the problem that the acquisition cost of system significantly increases.
And because about 1 ton box is carried very difficulty with manpower, therefore when dropping into manipulator or hoisting crane because of adjusting or repairing when stopping, the conveying of glass substrate just might be interrupted.Therefore, delivery system in the past might stop to make the Fabrication procedure of thin-type display device to stop because of dropping into manipulator or hoisting crane, causes whole Fabrication procedure capacity rating and descends.

Because it is resin mass 8 is the contact parts that contact with the pallet for single chip conveying 1 of stacked on top of one another, therefore preferred with the material formation that can suppress to produce dust.The resin mass 8 usefulness abrasion test height of present embodiment, the UPE that mechanical strength is good form.Even do not wear and tear owing to resin mass 8 contacts with each other also, can not produce dust, therefore can not pollute the lamellar article of conveying.
Resin mass 8 usefulness rivets or screw retention are on housing 2.Fig. 5 and Fig. 6 schematically represent resin mass 8 usefulness rivets or the state of screw retention on long limit member 2a.Fig. 5 represents the cutaway view of the length direction of long limit member 2a, and Fig. 6 represents the lateral plan of long limit member 2a.Resin mass 8 is connected to the par, the outside of long limit member 2a by the upper surface that is supported portion 23 lower surface, projection 21 and the top of main body 20 is fixed under the outstanding state of resin mass mounting hole 15a.
The upper surface of main body 20 that is fixed on the resin mass 8 on the housing 2 is than par, the outside 11 height of long limit member 2a.And the lower surface of main body 20 is lower than the lower surface of the flange 14 that is provided with on the outside par 11.
The pallet for single chip conveying 1 of present embodiment is to form the structure of also fixing as the resin mass 8 and the housing 2 of contact part with different materials respectively.Therefore, can be that contact part uses the material that suppresses to produce dust, can make contact part process easily, form.And other parts of housing 2 contact with other pallet for single chip conveying 1 or equipment etc. hardly, therefore can use the material of paying attention to intensity than the inhibition of dust more, can increase the degree of freedom of the material of selecting housing 2.
Put off until some time later the structure of bright housing 2 below.Long limit member 2a is connected with the union piece 10 of L word shape shown in Figure 7 with minor face member 2b.The union piece 10 of present embodiment is provided with 3, amounts to 6 connecting bores 18 on the limit of each bar L font.Connecting bore 18 relative position relation between mutually be configured to the connecting bore 16 of growing limit member 2a and minor face member 2b between relative position relation identical.
One side of union piece 10 overlaps with the end of long limit member 2a.Run through the connecting bore 16 of long limit member 2a and connecting bore 18 ground of union piece 10 simultaneously and play blind rivet, long limit member 2a of riveted joint and union piece 10.The another side of union piece 10 overlaps with the end of minor face member 2b.Run through the connecting bore 16 of minor face member 2b and connecting bore 18 ground of union piece 10 simultaneously and play blind rivet, minor face member 2b is connected with union piece 10 blind rivets.2 long limit member 2a are connected with 4 union piece 10 blind rivets with 2 minor face member 2b, form approximate rectangular housing 2.
The housing 2 that is connected to form by blind rivet is provided with space 19 (with reference to Fig. 1) on the top of the connecting portion of long limit member 2a and minor face member 2b.By space 19 is set, dust can not rest on connecting portion, and can easily carry out the clean and dry of housing 2.That is, by space 19 is set, dust can not put aside the connecting portion at housing 2, can obtain to take precautions against in advance the effect of polluting the lamellar article of placing.
The pallet for single chip conveying 1 of present embodiment sets up many frameworks 4 between the relative minor face member 2b of housing 2, form the placement section of lamellar article.Framework 4 uses certain thickness SUS304 plate, is processed into predetermined cross sectional shape by sheet metal.
The enlarged drawing of one end of framework 4 is illustrated among Fig. 8.Framework 4 forms the smooth installation portion 25 that is installed on the housing 2 in both sides, form the protrusion 26 that projects upwards between the par.The two ends of installation portion 25 are provided with the housing mounting hole 27 that is connected on the housing 2.The pin 28 of laying that the lamellar article of a plurality of supports are used is fixed on the protrusion 26.
Lay the high UPE of pin 28 usefulness resistance to abrasions and form, also can or not pollute lamellar article because of wearing and tearing produce dust even place lamellar article repeatedly.
Run through the housing mounting hole 27 of framework 4 and the frame mounting hole 17 ground riveter nails of housing 2, riveted joint housing 2 and framework 4.Because framework 4 possesses protrusion 26, so framework 4 at both endss have under the state of peristome and are connected on the housing 2.Therefore, housing 2 is not easy to put aside dust with the connecting portion of framework 4, and can easily carry out during clean pallet for single chip conveying 1 framework 4 parts clean and dry.
And, because framework 4 is formed with protrusion 26, so beam strength strong when using planar plate members.So framework 4 can the thinner sheet material of used thickness, can alleviate the weight of framework 4.
Intensity in order to determine to be placed on the position of the lamellar article on the pallet for single chip conveying 1 and to increase housing 2 bights has been inclined cross transom 6 between near long limit member 2a the bight of housing 2 and minor face member 2b.The perspective representation of transom 6 is in Fig. 9.Transom 6 and the framework 4 the same protrusions 26 that are provided with, 2 locating dowel pins 29 that are used to support the bight of laying pin 28 and the lamellar article of butt of lamellar article to carry out the riding position location are fixed on protrusion.
In order to determine the corner positions of lamellar article, be provided with the locating dowel pin 29 of transom 6, can guarantee that the every side and the size of the lamellar article of reality have the configuration of 2～3 mm clearance ground.The high UPE of locating dowel pin 29 usefulness resistance to abrasions forms, though in order to locate lamellar article repeatedly contact can or not pollute lamellar article because of wearing and tearing produce dust yet.
Figure 10 has schematically the represented stacked on top of one another state of multi-disc pallet for single chip conveying 1.And Figure 11 represents the cutaway view on every side of a resin mass 8 in 3 stacked pallet for single chip conveying 1.As shown in Figure 10 and Figure 11, enter the rake 13 of the pallet 1 of downside from top let-in other the rake 13 of pallet 1, by stacked like this.
By making the rake 13 that enters the pallet 1 of downside from top let-in other the rake 13 of pallet 1, can in less space, take care of more pallet when stacked.Height in the pallet below the stacked spacing of explanation and the pallet 1 that is placed on upside enter below---be the relation between the height of accommodation section 13b in, the whole height when a plurality of pallet for single chip conveying 1 of stacked present embodiment is described.
The pallet for single chip conveying 1 of this fact Example is stacked under the upper surface of the main body 20 that only is fixed on the resin mass 8 on the housing 2 and state that lower surface contacts with each other.The height of resin mass 8 be 1 thin plate article of safe containment accommodate height (H1), the partial sum framework 4 beyond the housing 2 of pallet for single chip conveying 1 does not contact with up and down pallet 1 when stacked.Therefore, pallet for single chip conveying 1 is determined height by resin mass 8, is that spacing is stacked to accommodate height (H1) promptly.
When pallet for single chip conveying 1 is spacing when stacked with the height of being determined by resin mass 8 (H1) of accommodating, enter the housing 2 of the pallet 1 of downside from top let-in other the housing 2 of pallet 1.If suppose that the lower surface of inboard par 12 of the pallet 1 of the upside that enters is 13a to the distance of the lower surface of the inboard par 12 of the pallet for single chip conveying 1 of downside, then clearly, said here height 13a equates with the height H 1 of resin mass 8.So, entering the height of rake 13 of the pallet 1 of downside from top let-in other the rake 13 of pallet 1---the height that is accommodation section 13b is that the height (H) of rake 13 deducts the height H 2 of accommodating height (H1).
It is irrelevant with the height (H) of rake that 1 needed height of the every increase of the sheet number of stacked pallet for single chip conveying 1 increases part, for stacked spacing is promptly accommodated height (H1).For example, the height of stacked n sheet rake is H, accommodate highly height for H1, accommodation section when being the pallet for single chip conveying 1 of H2, and whole height is with following formula (1) expression:
H1×n+H2……………(1)
From following formula as can be known, during stacked n sheet pallet for single chip conveying 1, to the most influential height of whole height for promptly to accommodate height H 1 with the proportional stacked spacing of stacked number.For example, though for the intensity that increases housing 2 the stacked pallet for single chip conveying 1 that has increased the height H of rake, the change of rake 13 height to the influence of whole height only in the height H 2 of the accommodation section of a slice 13b, very little to the influence of whole height.So, the pallet for single chip conveying 1 of present embodiment is by being provided with the accommodation section 13b that enters for from top let-in other the rake 13 of pallet 1 on the rake 13 of the pallet 1 of downside, even under the situation of the height that for example changes rake 13, can be stacked with less spacing.
As mentioned above, when the pallet for single chip conveying 1 of stacked on top of one another present embodiment, between pallet for single chip conveying 1 up and down, have only resin mass 8 contacts, housing 2 does not contact with other pallet for single chip conveying 1 fully with framework 4.Because resin mass 8 usefulness UPE form, therefore can not produce dust because of contact.And, therefore can not produce dust because housing 2 does not contact with other pallet for single chip conveying 1 with framework 4.So, dust can be do not produced yet, lamellar article can be do not polluted even the pallet for single chip conveying of present embodiment 1 is stacked.
And the pallet for single chip conveying 1 of present embodiment adopts the structure that is stacked in the weight of top pallet for single chip conveying 1 by resin mass 8 supporting layers, and the weight of the pallet for single chip conveying 1 of upside can not be loaded on the housing 2.Therefore, just passable as long as housing 2 possesses the intensity of weight of lamellar article of the weight that can support self and placement, to compare when adopting outer frame 2 supporting layers to be stacked in the structure of top pallet for single chip conveying 1, the intensity of requirement is little.Therefore, can easily obtain the intensity that housing 2 is required, can expendable weight.
As previously discussed, the cross sectional shape of the housing 2 of the pallet for single chip conveying 1 of present embodiment by flange 14, than its high slightly par, the outside 11, with its continuously and rake 13 that descends and form with continuous inboard par 12, the below of this rake 13, by suitably adjusting the height of rake 13, can easily obtain the intensity that housing 2 is required.
And the part of the rake 13 of the pallet for single chip conveying 1 of present embodiment plays a part for other the accommodation section 13b of pallet that enters from above.Thus,, when the stacked multilayer of reality pallet 1, also can be distance between the upper and lower, can in smaller space, take care of more pallet with the height (H1) of accommodating littler than the height of rake 13 even under the situation of the height that for example increases rake 13.
And, become the resin mass 8 of the contact part of pallet for single chip conveying 1 and the structure that housing 2 is fixed again up and down by adopting to form respectively with different materials, the resin mass 8 that is not easy to produce dust can easily be processed, be formed to the pallet for single chip conveying 1 of present embodiment.The material of housing 2 can use the material of paying attention to intensity, can enlarge the degree of freedom of the material selection of housing 2.
Though below describe concrete example of the present invention in an embodiment in detail, these only are examples, do not limit the scope of claim.The technology of being put down in writing in the claim scope comprises carries out all distortion or change to the above-mentioned concrete example of enumerating.For example, the method for attachment of the long limit member 2a of the housing among the embodiment 2 and minor face member 2b or be connected the method for attachment of local, housing 2 and framework 4 or be connected the place and can suitably change according to the size or the weight of the lamellar article of laying.And the shape of the shape of housing 2, resin mass 8 or configuration can be changed in the scope of detrimental effect effect not.
