[0057] In this embodiment, the 0-meter layer is the ground layer, which is used for the entry and exit of empty / full equipment. It is equipped with a conveyor belt, and the upper surface of the conveyor belt is flush with the ground, which is convenient for employees to enter the pallet to pick products. When the pallet is empty or the order color is switched, the elevator inserts the equipment and returns it to the warehouse. In order to achieve the best use effect, the 0-meter layer has a total of 19 equipment picking positions, and the number of the second elevators 9 is the same as the number of equipment picking positions.

[0058] During use, according to the order requirements of the assembly line, the control system transfers the required equipment from the main inventory area 4 to the line-side conveyor line 17 through the round-trip conveyor line 3, and the second elevator 9 stores the equipment in the assembly line side warehouse 6 for cache. When there is an order requirement in the 0m picking area, the system inserts the corresponding equipment in the assembly line side warehouse 6 to the 0m layer through the second elevator 9. When the equipment is empty, the empty equipment returns to the main inventory area 4 through the 5.5-meter layer conveyor line (the lower layer conveyor line of the line-side conveyor line 3); when switching to products of different colors and models, the second elevator 9 takes the equipment away and puts it back in the assembly line side warehouse 6.

[0059] In addition, the main inventory area 4 is connected to the round-trip conveyor line 3 and the line-side conveyor line 17. The equipment is transported to the unloading station in the spraying area through the 5.5-meter conveyor line. After the spraying unloading task is completed, it is transported to the stacker platform through the 8.9-meter layer conveyor line, and then transported to the main inventory area for storage by the stacker.

[0060] like Figure 4 As shown, a storage area round-trip conveyor 10 is provided between the second storage area and the assembly line side warehouse 6. The storage area round-trip conveyor 10 is connected to a bag turning area conveyor 11. An assembly conveyor 13 and a classification area 14 are also provided in the second storage area. The assembly conveyor 13 can transport the accessories entering the second storage area to the appropriate workers' positions.

[0061] See also Figure 2 , Figure 4 , the side of the assembly line side warehouse 6 is provided with a second storage area, which is located on the third floor. In this embodiment, the air height is 14.4m. Other workshop products are lifted to the second storage area by elevator. The manual / computer calls the pallet equipment, which is lifted to the 14.4m floor height by the second hoist 9 and the conveyor and enters the assembly line side of the storage area. The worker takes the parts from the transport equipment, inspects the appearance, scans the pallet equipment, and transports the equipment to the main storage area for storage.

[0062] See also Figure 2 , Figure 5 The spraying offline area 1 includes a lifting conveyor frame 101 and a first conveyor belt 102. The lifting conveyor frame 101 can be raised and lowered to facilitate workers to take automobile exterior parts; the automobile exterior parts taken off the spraying frame are transported to the loading area through the first conveyor belt 102, and the workers load the painted parts into the pallet device.

[0063] The replenishment conveyor line 2 includes a feed conveyor line 202, a discharge conveyor line 201 and a side waiting position 205. The discharge conveyor line 201 is provided with two groups of conveyor lines arranged side by side in the work station area. The discharge conveyor line 201 is connected to the upper conveyor line 301. A plurality of first rotating conveying positions 203 are provided on the discharge conveyor line 201. A plurality of side waiting positions 205 are provided on the side of the feed conveyor line 202. The side waiting positions 205 can provide space for empty pallet equipment to stay. The feed conveyor line 202 is connected to the lower conveyor line 302. A plurality of second rotating conveying positions 204 are provided on the feed conveyor line 202.

[0064] In this embodiment, in order to achieve the best economic and usage effects, two first hoists 8 are arranged side by side.

[0065] like Figure 6 As shown, the assembly line side warehouse 6 includes a first line side warehouse area 601, a second line side warehouse area 602 and a third line side warehouse area 603. The first line side warehouse area 601 is located above the second line side warehouse area 602, and the line side conveyor line 17 is located between the first line side warehouse area 601 and the second line side warehouse area 602. The first line side warehouse area 601 and the second line side warehouse area 602 can both be connected to the second elevator 9 arranged side by side, and the third line side warehouse area 603 is connected to the side of the second elevator 9 away from the line side conveyor line 17; thereby, the second elevator 9 can transport the pallet equipment to the first line side warehouse area 601, the second line side warehouse area 602 or the third line side warehouse area 603.

[0066] like Figure 7 As shown, the main inventory area 4 includes a plurality of shelves 401 and a plurality of lane palletizers 402. A palletizer platform is provided between the upper conveyor line 301, the lower conveyor line 302 and the shelves 401. The palletizer platform can facilitate the lane palletizer 402 to transport or store pallet equipment. Figure 8 shown.

[0067] like Fig.10 As shown, several groups of fire-proof pipes and sprinklers are arranged in layers in the main storage area 4. The fire-proof pipes are connected to the original fire hydrant water supply system, and the main pipes of the fire-proof pipes are DN150 pipes, and the pipes connecting the sprinklers are DN65 pipes; thus, the fire-fighting needs of the main storage area can be met.

[0068] See also Figure 1-Figure 2 Since the spraying offline area 1 and the main storage area 4 are set in two relatively independent workshops, a fireproof roller shutter is provided above the area where the round-trip conveyor line 3 and the supply conveyor line 2 are connected. When the fireproof roller shutter is lowered, the main storage area 4 can be separated from the spraying offline area 1. Therefore, a gap is reserved between the round-trip conveyor line 3 and the supply conveyor line 2; in order to meet normal conveying needs, the conveyor at the connection between the round-trip conveyor line 3 and the supply conveyor line 2 is set as a telescopic line conveyor 16.

[0069] like Fig.11 and Fig.12 As shown, the telescopic line conveyor 16 includes a protective plate 1601, a side support frame 1602, a telescopic frame 1603, a driving wheel 1605 and a tensioning wheel 1606. The side support frame 1602 is provided with two groups, and the protective plate 1601 is arranged above the side edges of the two groups of side support frames 1602; the upper sides of the side support frames 1602 are provided with guide plates 1613, and the side support frames 1602 are installed with a conveying chain 1604 and a driving wheel 1605 for ensuring the operation of the conveying chain 1604. A tensioning wheel 1606, an adjusting wheel 1607, a first guide wheel 1609, a second guide wheel 1611 and a third guide wheel 1612; one end of the side support frame 1602 is provided with a telescopic frame 1603, the telescopic frame 1603 is provided with a telescopic guide slot 1614, and the telescopic guide slot 1614 is installed on the side support frame 1602; the second guide wheel 1611 is installed on the telescopic frame 1603, and the third guide wheel 1612 is arranged at one end of the side support frame 1602 away from the telescopic frame 1603.

[0070] The driving wheel 1605 is arranged on the right part of the side support frame 1602 , and a tensioning wheel 1606 is arranged above the driving wheel 1605 ; the tensioning wheel 1606 is closer to the third guide wheel 1612 than the driving wheel 1605 .

[0071] The adjusting wheel 1607 is arranged on the left part of the side support frame 1602, and a first guide wheel 1609 is arranged below the adjusting wheel 1607, and the first guide wheel 1609 is closer to the telescopic frame 1603 than the adjusting wheel 1607; the adjusting wheel 1607 is connected to a second telescopic rod 1608 through a support frame, and the second telescopic rod 1608 is connected to a mounting seat reserved on the side support frame 1602.

[0072] The telescopic frame 1603 is connected to a first telescopic rod 1610 , and the first telescopic rod 1610 is also installed on the side support frame 1602 .

[0073] The conveying chain 1604 passes through the second guide wheel 1611, the adjusting wheel 1607, the first guide wheel 1609, the tensioning wheel 1606, the driving wheel 1605 and the third guide wheel 1612 in sequence to form a closed-loop conveying chain.

[0074] During normal use, the telescopic frame 1603 is in an extended state, at which time the first telescopic rod 1610 and the second telescopic rod 1608 are both in an extended state; when the telescopic frame 1603 is contracted, the first telescopic rod 1610 and the second telescopic rod 1608 are both contracted. In order to ensure that the conveyor chain 1604 does not fall off the wheels during the telescopic process, the first telescopic rod 1610 and the second telescopic rod 1608 are telescoped at the same time, and the telescopic stroke of the first telescopic rod 1610 is larger than that of the second telescopic rod 1608.

[0075] In addition, when the paint parts of the automotive exterior parts are unloaded in the spraying line area, two main inspectors and two main polishing warehouse personnel are configured for each unloading station of the paint line. The inspectors first scan the product, inspect it on the sled, and then remove the product and put it in the middle buffer area for polishing. The empty tool supply is automatically bound to the current station. If the product quality is qualified, the warehouse personnel will scan it into the tool; if the quality is defective, the warehouse personnel will optimize the polishing and then scan it into the tool; if the product is unqualified, the inspector will scan it and put it back on the sled to the first floor. All unloading stations are equipped with manual control selectors and have the function of lifting the machine down to the first floor for unloading operations.

[0076] On the assembly line, the assembly line personnel take the parts from the equipment and send them to the inspection area for the inspection personnel to verify the product status. If qualified, they are placed on the accumulation chain in order to be transferred to the assembly area for assembly: if there are minor quality problems, they are polished and optimized and placed on the conveyor belt to be transferred to the assembly area; if the product is judged to be scrapped, it is placed in the scrap area, triggering a signal, calling the product equipment of this color again or taking the parts from the line side warehouse until this product is qualified before the next product inspection.

[0077] In order to achieve better use effect, the assembly line side warehouse has a pre-sorting switching function, and the specific steps are as follows:

[0078] The personnel picking up parts on the assembly line trigger the switching device of the second elevator, and the inspection personnel judge the product quality status and trigger the request for re-order (the pickup point is equipped with an all-in-one machine, and the inspection point is equipped with a display screen).

[0079] a. If the color of the subsequent order is still the same, the current equipment does not need to be returned to the line warehouse.

[0080] b. If the quality of the same batch is too low, the quality management personnel will decide whether to freeze the batch. If necessary, mark it and return it to the main warehouse, and transfer another batch of products from the main warehouse to the line-side warehouse.

[0081] c. If a scrap replacement order is required, the second elevator will deploy the corresponding replacement equipment to the ground floor after completing the current action.

[0082] d. A single product on the assembly line in the pre-sorting area is operated by two second elevators and a double-layer conveyor with a green light (the person picking up the item picks up the item according to the green light prompt, and after leaving the safety grating, he needs to press the confirmation button).

[0083] e. The double-layer conveyor is connected to the second elevator and chain conveyor, and the three work together to save delivery time. When the color of subsequent orders on the production line remains unchanged, or the two colors appear alternately, the double-layer conveyor is required to control the up and down movement of the pallet in and out, and the operation of the second elevator is not involved.

[0084] f. Design a temporary storage container near the inspection station to store the parts of the next order after the parts being inspected.

[0085] g. Set up a cache warehouse at the line side. (Take the previous example) Each color and each product type is stored in the cache warehouse. When unqualified products or urgent order tasks appear in the production process, you can urgently take parts from the line side warehouse to the production line for assembly. When a certain type of cache warehouse is empty, you need to scan the code from the line side warehouse to replenish it in the cache warehouse.

[0086] In addition, for the platter function of platter area 7, if the qualified rate of the paint line is low, the platter area function will be activated, and the platter area system can automatically determine whether platter operation is required according to the status of the pallet and product (for example, if the critical point is defined as 70% loading capacity, then platter is not required if it is greater than 70%). If not required, it will be directly put into storage; if required, it will enter the platter area.

[0087] Furthermore, the monitoring and scheduling system in this implementation realizes task decomposition scheduling and optimization, status monitoring and motion control of the actuators, and is the core software to ensure the normal operation of the three-dimensional warehouse logistics system, including scheduling management and monitoring management. The monitoring and scheduling layer transmits the operation command to the control system through PROFINET industrial Ethernet, and then transmits it to stackers, conveyors and other equipment to control each actuator.

[0088] In addition, if Fig. 9 As shown, a plurality of third elevators 15 are also provided on the side of the round-trip conveyor line 3. The third elevators 15 can switch the conveyor line when a failure occurs at a single line-side conveyor line 17, thereby ensuring the normal operation of the entire storage system.

[0089] The round-trip conveyor line provided by the present invention can directly convey new products from the spraying offline area to the assembly line side warehouse, and can also call the inventory products from the main inventory area to the assembly line side warehouse, which can greatly improve the rapid call of exterior parts of different colors and specifications, without having to wait for the products in the offline area to be stored first and then call them. In addition, for the products returned or unqualified from the assembly line, they can also be quickly transported from the assembly line side warehouse to the main inventory area.

[0090] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
