The tray is a carrier for stacking cargoes, a tool for mechanized loading/unloading and

handling. The tray puts the scattered small cargoes and containers in a certain quantity, and it

transports cargoes in unit and form a transportation system of a container unit together with a

forklift. Therefore, the tray has become an indispensable and important tool for a modem

logistics system, which is widely used in various countries of the world.

Molded trays are generally made of recyclable resources, such as wood, bamboo and its

recycled materials, processing residues, wood/bamboo forest cutting and tending residues, as

well as crop straws, the production process usually adopted is hot pressing method, and its raw

materials and processes are environmental-friendly. In addition, the production technology of

molded trays has experienced continuous developments and improvements, so the proportion of

molded trays in the tray market is increased year by year.

gradually applied to the production line to replace manual loading and realize automated cargo

loading. Most of the existing production lines are only equipped with simple photoelectric

sensors, which can only be used to distinguish whether the pallet moves to the specified position.

If there are multiple different types of pallets on the production line, the production line will not

be able to distinguish which type of pallet moved to the specified position. Therefore, it is

impossible to load according to the specific pallet type; in addition, when the molded pallet is

transported on the production line, due to the existence of the existing molded pallets, the supporting feet are often stuck in the position where the two conveyor belts meet As a result, the molded pallets cannot move with the conveyor belt, or the molded pallets are turned over on the conveyor belt; in addition, people are studying more and more deeply on the molded pallets, how to make better use of environmentally friendly materials, and how to design the reinforcing ribs on the molded pallets The type and its arrangement position to improve the bearing and strength of the pallet are the key research directions of the molded pallet.

To sum up, the present invention has the following beneficiary effects:

1. The assembled molded tray of the present invention comprises a molded panel, a

support block, and a bottom plate, which is applicable for automated production lines,

multi-layer stacking and various racks; and it meets the requirements of mechanical automation

and intelligent loading.

2. The assembled molded tray has a detachable support block, and the support block may

not be assembled during the transportation, which reduces the distance between the adjacent

trays when stacking them up, thereby facilitating the tray transportation.

3. The support block also has a third plane for pasting an identification, the identification

may be a QR code, and the QR code can be used to record information such as the production

date of the pallet, the material used for the tray, the maximum carrying capacity of the tray, and

information about cargoes on the tray and some other information, the identification may also be

4. RFID chip is set in the support block, which can be applied in automated production

lines for reading and writing remote data.

5. The bottom plate arranged in the assembled tray enlarges the contact area between the

assembled tray and the ground, so that the assembled tray may not easily slide on the ground,

and the objects carried on the tray may not easily fall off; simultaneously, the bottom plate can

enhance the overall anti-bending ability of the assembled tray and make the assembled tray not

easily deformed when carrying objects, thereby greatly enhancing its carrying capacity.

6. The bottom plate plays an active role in automatic loading of cargoes on the production

line. Due to the existence of the brackets, it is common that the conventional molded trays have

their brackets stuck in the junction of the two conveyor belts, which causes the tray fail to move

with the conveyor belt or leads to overturning of the tray on the conveyor belt, and arrangement

of the bottom plate can solve this problem, with the help of the bottom plate the tray perfectly

achieves the transition between the conveyor belts.

7. The stiffener structure is improved, by using different types of stiffeners, such as

connecting stiffeners, partitioned stiffeners, semi-partitioned stiffeners, ring stiffeners and

right-angle stiffeners, the bearing capacity of the molded panel is greatly improved without

changing the production process.

8. The assembled molded tray may install the support block and the bottom plate or not

according to the requirements of the application scenarios. For example, when the tray is in

scenarios where the cargo carrying capacity is small and the ground is relatively flat and dry, the

molded panel may be used directly without assembling a support block and a bottom plate; if the

tray is used in scenarios where the cargo carrying capacity is small and the ground is relatively

rough and wet, then molded panel is preferably installed with the support block to prevent the

V

cargoes from getting damp; if it is used in some scenarios where the cargo carrying capacity is

high and the ground is smooth and wet, then the molded panel is preferably installed with the

support block and the bottom plate; the complete assembled molded tray has high carrying

capacity, and has the advantages of preventing the cargoes from getting damp, and guaranteeing

stable placement.

9. A groove is arranged on the bottom plate, and the groove can further improve the

anti-sliding effect of the assembled tray.

Detailed description of embodiments

Combining the drawings and the detailed description, the inventions are further described

as follows. It should be noted that the embodiments are detailed description of the present invention and do constitute any limitation on the invention, all characteristics, or the steps involved in all the methods or processes disclosed in embodiments of the present invention, except the mutually exclusive characteristics and/or steps, can be combined in any way.

An assembled molded tray, as shown in FIGS.2-4, comprises a molded panel 10, wherein a

reserved area 70 is configured on the molded panel 10, a support block 22 is detachably installed

on the reserved area 70, the support block is also called a detachable bracket. A conventional

molded tray is formed by pressing materials with a mold, the molded panel of the molded tray is

integrated with the bracket, and the bracket cannot be removed; during the press forming process

of a molded tray, it is impossible to ensure that all the materials on the mold are evenly

distributed, at least one bracket on the finished molded tray is slightly thinner than the bracket at

other positions; when these molded trays carry relatively light-weighted cargoes, the defect of

the bracket may not be obvious; while when these molded trays carry the cargoes with the mass

close to its maximum carrying capacity, the position of the thin bracket may easily get damaged,

which will result in scrapping of the entire tray. When the support block 22 is used, the support

block 22 is independently processed, so it can be ensured that the loading capacity of all support

blocks 22 are the same, which can avoid the bracket at a certain position from being easily

damaged; simultaneously, when the tray is carrying cargoes, even the cargoes on the tray are not

uneven distributed, which causes the support block at a certain position to bear particularly

heavy pressure and results in damage of the support block at the position, at this time, the

damaged support block can be removed and replaced with a new one, then the tray can still be

used normally, thereby greatly reducing the scrap rate of molded trays. A bottom plate 23 is

arranged on the support block 22, and the bottom plate is also called a brace; the support block is

installed in the said reserved area of the molded panel 10, in order to solve the problem of easy

damage to the bracket and easy scrap of the tray, but this technical solution also brings a new

technical problem, that is, the stability of "molded panel 10 after installing the support block" on the ground is not as good as the stability of "molded tray with an integral molding panel and bracket" on the ground; this is because the support block is installed later, and it is difficult to ensure that all support blocks are on the same plane when the support blocks are installed; therefore, when the molded panel carries cargoes, the case may that one of the support blocks may has a large bearing capacity and a certain support block has small bearing capacity; after installing the bottom plate on the supporting block, the bottom plate is connected to at least two supporting blocks, and the bottom plate can combine the bearing capacity between the connected supporting blocks so that the assembled molded tray is placed on the ground steadily. When the conventional molded trays are stacked with two layers of cargoes, for specific, No.1 tray is placed on the bottom side, and the No.1 tray is loaded the cargoes; while the No.2 tray is placed on the top of the cargoes, and the No.2 tray is loaded with the cargoes on the upper side. Because the top of the cargoes is generally not very flat, some brackets on the conventional molded tray

(No.2 tray) may be suspended, which may result in unstable placement of trays; while, if the

assembled tray of the present invention is used, the bottom plate increases the contact area

between the tray and the cargoes, and also balances the force between the support blocks, this

ensures the No.2 tray maintains a good contact with the top of cargoes, thereby greatly

improving the placing stability. Further, as shown in FIG.5, the support block 22 has at least two

planes: a first plane 80 and a second plane 81, and the first plane 80 and the second plane 81 are

respectively connected to the reserved area 70 and the bottom plate 23, and the support block 22

also has a third plane 82 for pasting an identification, and the third plane 82 is not parallel to the

first plane 80 or the second plane 81, the identification may be a QR code, and the QR code can

be used to record information such as the production date of the pallet, the material used for the

tray, the maximum carrying capacity of the tray, and information about cargoes on the tray and

some other information. The identification may also be a label of a manufacturer, a barcode or

others that can record information; the third plane 82 generally faces the outer side of the tray,

IU

thus to make it convenient for an operator to read. A designated equipment on the production

line can identify the specific model of the tray by reading the information indicated by the

identification, thus to facilitate the production line to load cargoes according to different trays.

The assembled molded tray comprises a molded panel, a support block, and a bottom plate,

which is applicable for automated production lines, multi-layer stacking and various racks; and it

meets the requirements of mechanical automation and intelligent loading.

Preferably, as shown in FIG.25 and FIG.26, the support block 22 is arranged in the third

plane 82 and is provided with a mounting slot 88, an RFID chip 87 is fixed in the mounting slot

88 and the RFID chip is also called RFID tag, electronic tag, radio frequency tag, transponder

and data carrier. This is a non-contact automatic identification technology able to store a large

amount of data. It recognizes a target object automatically and obtains related data through radio

frequency signals without need of manual intervention, applicable in various harsh environments.

The supporting block 22 is also provided with an identification 86, and the identification 86 can

seal a RFID chip 87 in the support block 22, and the identification 86 is waterproof. Arranging a

RFID chip in the support block 22 has the following advantages: 1. Record more data; 2.

Applicable for automatic production line; 3. Support remote data reading through a specific

reading device, allowing the distance reach up to 10m; it avoids the cumbersome of scanning a

QR code to read information, because when reading a QR code users have to align and focus the

QR code; while sampling a RFID chip is much easier.

In order to ensure that the assembled molded trays and the loaded cargoes are kept stable on

a horizontal surface, the plane of the bottom plate 23 and the plane of the molded panel 10 must

be in a horizontal level. Preferably, the first plane 80 is parallel to the second plane 81, when the

bottom plate 23 is placed on a horizontal surface, the plane of the molded panel 10 will remain

horizontal.

Preferably, as shown in FIG.5, in order to reduce the production cost of the support block

22, the support block 22 is required to be square as a square support block 22 is easy to process

and the processing cost is low. A round corner 84 is arranged at the contour edge of the support

block 22, and the rounded corner 84 can prevent the edge of the support block 22 from causing

wear and even cuts to a surrounding object and the environment.

Preferably, as shown in FIG.1, a recess 20 is arranged in the reserved area 70, and the

thickness of the recess 20 is thinner than that of the molded panel 10. It will facilitate the

connection between convenient the reserved area 70 and the support block 22. Specifically, four

round recesses 20 are arranged in the reserved area 70, and the connection to the support block

22 is achieved by driving connecting nails into the round recesses 20; it should be ensured that

the position of the connecting nails is reasonable and accurate when driving the connecting nails,

so as to prevent the connecting nail from passing through the side of the support block 22.

Compared with a common detachable connection method, the connection method adopted by the

present invention is stronger, which is suitable for the tray to carry objects for a long time.

Preferably, a reinforcing structure is arranged on the molded panel 10, and the reinforcing

structure is mainly in the form of a stiffener, the stiffener is a groove structure pressed on the

surface of the molded panel 10, and the stiffener includes connecting stiffeners, partitioned

stiffeners, semi-partitioned stiffeners, ring stiffeners, right-angle stiffeners, etc. Connecting

stiffeners, partitioned stiffeners and semi-partitioned stiffeners are mainly distinguished based on

whether they are connected to other stiffeners or brackets: the ones with both ends connected to

the brackets or to other stiffeners are called connecting stiffeners; the ones with both ends not

connected to the brackets or to other stiffeners are called partitioned stiffeners; the ones with one

end connected to the brackets or to other stiffeners and the other end not connected to the

brackets or to other stiffeners are called semi-partitioned stiffeners. Ring stiffeners and

right-angle stiffeners are mainly distinguished by the shape of stiffeners: the stiffeners both ends

of which are connected to form a closed loop are called ring stiffeners; the stiffeners with s

IZ/_

-degree corner are called right-angle stiffeners. The specific application of the stiffeners will

be described in detail below.

The molded panel 10 is square, when the square molded panel 10 is loaded with cargoes,

the adjacent molded panels 10 can be bonded together and the occupied area is relatively small,

so the most commonly used trays in life are also square, although the square molded panel 10 is

used as an example in the present invention, it does not constitute a constraint to the combination

mode of the molded panel 10, the support block 22, and the bottom plate 23; the technical

solution used in this application also applies to other trays, for example, round tray and triangular

tray, any changes or replacements that come into mind without any creative work shall be within

the protection scope of the present invention. The outer edges of four corners of the molded

panel 10 are made into arc, or 45, 600 chamfers (determined according to the actual

requirements), which can reduce the wear and even cuts of the tray to surrounding objects and

the environment.

Some embodiments of assembling the molded panel 10 and the support block 22 are given

below.

Embodiment 1, as shown in FIG.1-FIG.5.

The embodiment provides a method for assembling the molded panel 10 and the support

block 22,and no bracket is configured on the molded panel 10; in this embodiment, the reserved

area 70 comprises a central reserved area 11 located at the center of the molded panel 10, a

corner reserved area 13 at the corner of the molded panel 10, and an edge reserved area 12 at

middle of the edge of the molded panel 10; accordingly, the support block 22 comprises a central

support block 71, a corner support block 73, and an edge support block 72, and the central

support block 71, the corner support block 73, and the edge support block 72 are respectively

installed in the central reserved area 11, the corner reserved area 13 and the edge reserved area

I -Y

12.

The central support block 71, the corner support block 73, and the edge support block 72

may be the same or different, and the same herein means the same material and the same shape.

In order to reduce the production cost of the assembled molded tray, the central support block 71,

the corner support block 73, and the edge support block 72 preferably adopt the same support

block.

Embodiment 2, as shown in FIG.6.

block 22, and a central bracket 60 is arranged at the central position of the molded panel 10; in

this embodiment, the reserved area 70 comprises a corner reserved area 13 at the corner of the

molded panel 10, and an edge reserved area 12 at middle of the edge of the molded panel 10;

accordingly, the support block 22 comprises a corner support block 73, and an edge support

block 72, and the corner support block 73 and the edge support block 72 are respectively

installed in the corner reserved area 13 and the edge reserved area 12.

The corner support block 73 and the edge support block 72 may be the same or different,

and preferably, the corner support block 73 and the edge support block 72 preferably adopt the

same support block.

Embodiment 3, as shown in FIG.7.

The embodiment provides an assembling method of the molded panel 10 and the support

block 22, and a central bracket 60 is arranged at the central position of the molded panel 10, and

a corner bracket 61 is arranged at the corner position; in the embodiment, the reserved area 70 is

an edge reserved area 12 at middle of the edge of the molded panel 10; accordingly, the support

block 22 is an edge support block 72, and the edge support block 72 is installed in the edge reserved area 12.

Embodiment 4, as shown in FIGS.8-11.

block 22, a central bracket 60 is arranged at the central position of the molded panel 10, and an

edge bracket 62 is arranged at the middle position of the edge; in the embodiment, the reserved

area 70 is a corner reserved area 13; accordingly, the support block 22 is a corner support block

73, and the corner support block 73 is installed in the corner reserved area 13.

The above described an embodiment of assembling a variety of molded panel 10 and the

support block 22, which are respectively: 1 without bracket; 2. without corner bracket and edge

bracket; 3. without edge bracket; 4. without corner bracket. There are totally four cases. The

following three embodiments are not given: 1. Missing a central bracket; 2. Missing a central

bracket and a corner bracket; 3. Missing a central bracket and an edge bracket. Because the

embodiments of the three missing are not preferred solutions, and the practicability is far inferior

to the embodiments 1-4 given above. Because the molded panel 10 misses a central bracket, the

carrying capacity of the molded panel 10 will be greatly reduced when it is used independently,

and it is easy to break when loaded with cargoes; in addition, even if a corresponding central

support block is installed on the molded panel lacking of a central bracket to improve its carrying

capacity; however, the central support block is at the middle position of the molded panel, the

identification pasted on the block is not easy to read; relatively, the identification pasted on the

corner support block and the edge support block are pasted are much easier to read; due to the

above two technical disadvantages, the three embodiments are not deemed as preferred solutions.

If you choose to use the said RFID chip in the support block, the technical problem will not exist,

but application of the RFID chip may greatly increase the production cost of the assembled tray,

I -)

hence, most factories still prefer to paste identification during production. Though the present

invention does not give embodiments of the latter three choices, the changes or substitutions in

the three embodiments that are made without creative work are just simple applications, and

should be covered within the protection scope of the present invention in combination with the

technical solutions.

The bottom plate 23 is introduced based on embodiment 1 to embodiment 4; arrangement of

the bottom plate 23 enlarges the contact area between the assembled tray and the ground, so that

the assembled tray may not easily slide on the ground, and the objects carried on the tray may

not easily fall off; simultaneously, the bottom plate 23 can enhance the overall anti-bending

ability of the assembled tray and make the assembled tray not easily deformed when carrying

objects, thereby greatly enhancing its carrying capacity; additionally, the bottom plate 23 plays

an active role in automatic loading of cargoes on the production line. Due to the existence of the

brackets, it is common that the conventional molded trays have their brackets stuck in the

junction of the two conveyor belts, which causes the tray fail to move with the conveyor belt or

leads to overturning of the tray on the conveyor belt, and arrangement of the bottom plate 23 can

solve this problem, with the help of the bottom plate the tray perfectly achieves the transition

between the conveyor belts. The conventional molded tray can also adopt the technical solution

of the present invention: a bottom plate is directly fixed on the bracket, but relatively speaking, it

is not as well as expected if the bracket and the bottom plate are fixed by glue, the bottom plate

may not easily fall after long-time use; if the bracket and the bottom plate are fitted by

connecting nails, as the bracket is thin, after the connecting nails are screwed in, there may be

small holes on the bracket, which will reduce the carrying capacity of the tray. The molded panel,

the support block, and the bottom plate are combined; the support block is solid, the carrying

capacity of the assembled tray will not be affected after the connecting nails are driven in;

simultaneously, the support block is firm and have a long service life after the connecting nails

IV

are driven, therefore, the assembly method of the molded panel, the support block and the

bottom plate is preferred. Some embodiments of assembling the molded panel 10, the support

block 22 and the bottom plate 23 are given below.

Embodiment 5, as shown in FIG.4 and FIG.11.

The embodiment provides a method for assembling the bottom plate 23 on the molded

panel 10 and the support block 22 based on embodiments 1-4. In FIG.4, there are three bottom

plates 23, wherein two bottom plates 23 are respectively connected to two corner support blocks

73 installed in the corner reserved areas 13 and the edge support block 72 installed in the edge

reserved area 12, and the remaining one bottom plate 23 is connected to two edge support blocks

72 installed in the edge reserved area 12 and one central support block 71 installed in the central

reserved area 11. In FIG.11, there are three bottom plates 23, wherein two bottom plates 23 are

respectively connected to the corner support blocks 73 installed in the two corner reserved areas

13 and an edge bracket 62, and the remaining one bottom plate 23 is connected to the two edge

brackets 62 and one central bracket 60.

In FIG.4, each bottom plate is connected to three support blocks; in FIG.11, one bottom

plate is connected to three brackets, and the other bottom plate is connected to the bracket and

the support block. Although as shown in FIG.4 and FIG. Ithe objects that are connected to the

bottom plate are different, they are substantially the same: the bottom plate is connected to three

objects (bracket or support blocks), and finally the bottom plate is in "E" shape, therefore, any

changes or replacements that come into mind without any creative work, for example replacing

the bracket connected to the bottom plate with the technical solution of the present invention,

shall be covered within the protection scope of the present invention.

Preferably, the outer contour edge of the bottom plate 23 does not exceed the edge of the

molded panel 10, this design makes the tray occupy a small space when it is placed on the

ground.

The above Embodiments 1-8 describe various different assembly modes among the molded

panel 10, the support blocks 22 and the bottom plates 23. The molded panel 10 without brackets

described in Embodiment 1 has the best market application prospects. Due to the fact that the

molded panel of the molded tray in such assembly modes is not provided with the brackets, the support blocks may not be assembled during transportation, the support blocks, the molded panel and the bottom plates are separated, so that the distance between adjacent trays is reduced during stacking of the trays, and tray transportation is facilitated. Meanwhile, the molded panel 10 without the brackets can be provided or not provided with the support blocks 22 and the bottom plates 23 according to application needs of usage scenarios. For example, when the molded panel in Embodiment 1 is applied under the situation where the cargo carrying capacity is small and the ground is relatively flat and dry, the molded panel 10 may be used directly without assembling the support blocks 22 and the bottom plates 23; if the molded panel 10 in

Embodiment 1 is applied under the situation where the cargo carrying capacity is small and the

ground is relatively rough and wet, then the molded panel 10 is preferably installed with the

support blocks 22 to prevent cargoes from getting damp; if the molded panel 10 in Embodiment

1 is applied under the situation where the cargo carrying capacity is high and the ground is

smooth and wet, then the molded panel 10 is preferably installed with the support blocks 22 and

the bottom plates 23; the complete assembled molded tray has the advantages of being high in

carrying capacity, preventing the cargoes from getting damp and guaranteeing stable placement.
