Description

Technical Field

[0001] This invention relates to the field of cold chain logistics warehousing technology, and in particular to an automated sorting and containerization system for cold chain logistics warehousing. Background Technology

[0002] Cold chain refers to a special supply chain system where certain food raw materials, processed foods or semi-finished products, special biological products, and pharmaceuticals, after being acquired, processed, and inactivated, are kept at a specific low temperature environment necessary for the product throughout the entire process of processing, storage, transportation, distribution, retail, and use. This minimizes loss, prevents contamination and spoilage, and ensures food safety, biosafety, and pharmaceutical safety. Cold chain logistics generally refers to a systematic project that ensures refrigerated and frozen foods are kept at a specified low temperature environment throughout all stages from production, storage, transportation, and sales to consumption, in order to guarantee food quality and reduce food loss. Currently, after production and processing, large quantities of cold chain goods are generally transferred to cold chain warehouses for refrigeration to maintain the freshness of frozen foods, pharmaceuticals, or biological products, before being sorted and distributed.

[0003] Before goods leave the cold chain warehouse, they need to be sorted and packaged together according to order information to facilitate centralized transportation and save packaging and transportation resources. Existing cold chain warehouse management systems have low levels of automation; goods are primarily sorted manually during outbound transport. After sorting, the ordered quantity of goods needs to be packaged together in an insulated box. To ensure the stability of product quality during transportation, a certain amount of cooling materials, such as ice packs, needs to be added to the insulated box as needed to maintain the goods at a consistently low temperature during transport and prevent frozen or chilled goods from spoiling due to temperature increases.

[0004] Currently, the standard outbound process for cold chain warehousing after receiving a system order is as follows: First, based on the order information, an automated sorting system sorts all the goods in the order and gathers them together; second, insulated boxes are manually retrieved, and all the goods in the order are packed into the insulated boxes, completing the picking of all cold chain goods in the order; then, the sorted and packed insulated boxes are transferred to the next process, and ice packs are added as needed to cool down and maintain the temperature of the goods; finally, the insulated boxes are sealed again, transferred out of the warehouse, and transported via cold chain.

[0005] However, existing cold chain warehousing typically relies on manual packing, which is inefficient, labor-intensive, and prone to errors. Furthermore, manual packing involves direct hand contact with the goods, easily transferring bacteria from hands to the products, inevitably causing contamination and posing potential safety risks. Moreover, the current cold chain warehousing process is cumbersome and results in low operational efficiency. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned deficiencies in the existing cold chain warehousing process of sorting and packing goods, and to propose an automated sorting and containerization system for cold chain logistics warehousing that is fast in packing goods, saves time and labor, has a low risk of contamination, and has high warehousing operation efficiency.

[0040] The present invention adopts the above technical solution and has the following technical effects compared with the prior art:

[0041] (1) The automatic sorting and containerization system for cold chain logistics warehouses connects the empty box conveyor line, the chilled goods conveyor line, the ice pack conveyor line and the container conveyor line to the container platform in a centralized manner. The container platform realizes the feeding of insulated boxes, the centralized packing of picked goods, the packing of ice packs and the transfer to the next process in sequence, which greatly simplifies the outbound process of cold chain logistics and improves the operating efficiency of cold chain warehousing.

[0042] (2) The support platform, rotating container mechanism, rotating transmission mechanism, ring transmission mechanism, fixed transmission mechanism and container conveying mechanism of the container are integrated into one unit, with a compact structure and small equipment volume. The whole unit uses a single drive motor to achieve intermittent operation, which simultaneously realizes the purpose of workstation transfer and stop for packing. The sorting and packing effect is high, saving time and effort.

[0043] (3) The fan-shaped gear disk with an “8”-shaped sector gear structure and the fixed transmission gear set at the outer point realize the intermittent meshing connection between the fan-shaped gear disk and the ring gear disk. The angle of the fan-shaped gear disk is designed to be 90°, so that when the fan-shaped gear disk rotates one revolution, its quarter revolution synchronously drives the rotating disk and the heat preservation box on the work station slot to rotate for work station circulation, and three-quarter revolution disengages from the fixed transmission gear and is in a stationary state, which is convenient for putting heat preservation boxes, goods or ice packs into the corresponding work station. This intermittent rotation structure is ingenious and precise, and can alternately realize the purpose of work station rotation and material feeding.

[0044] (4) The container conveying mechanism is mainly composed of three sections of conveying rollers connected in sequence and laid along the flow direction of the insulated box to ensure the accuracy of the transfer direction of the insulated box and avoid the problem of deviation or jamming. At the same time, the thrust of the rotating container mechanism is used to indirectly realize the automatic transfer and discharge of the insulated box at different work positions. Moreover, the container conveying mechanism with roller structure design greatly facilitates the transfer connection with each conveyor belt and ensures the stability and speed of the transfer of the insulated box.

[0062] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0063] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0064] Example 1 Figure 1 As shown, an automated sorting and containerization system for cold chain logistics warehousing is provided. The system mainly includes an empty box conveyor line 100, a chilled food conveyor line 200, an ice pack conveyor line 300, a containerization platform 400, and a containerization conveyor line 500. The tail ends of the empty box conveyor line 100, the chilled food conveyor line 200, and the ice pack conveyor line 300, and the front end of the containerization conveyor line 500 are respectively set around the containerization platform 400. By centrally arranging the containerization platform 400, the empty box conveyor line 100, the chilled food conveyor line 200, the ice pack conveyor line 300, and the containerization conveyor line 500 are connected to the containerization platform 400 as a whole. It also has multiple material inlets and one material outlet, thereby meeting the needs of picking and packing various types of boxes.

[0065] like Figure 1 As shown, the empty box conveyor line 100 mainly includes an empty box conveyor belt 101 and an empty box buffer position 102. One end of the empty box conveyor belt 101 extends to the empty box buffer position 102, and the other end extends to the empty box inlet on one side of the container table 400. An automated handling robot transfers the empty insulated boxes on the empty box buffer position 102 to the empty box conveyor belt 101. Then, the empty box conveyor belt 101 is started to transport the empty insulated boxes sequentially into the workstation slots 245 in the empty box inlet, realizing automatic feeding of the insulated boxes.

[0066] like Figure 1As shown, the chilled goods conveyor line 200 mainly includes a chilled goods conveyor belt 201, a picking station, and a chilled goods buffer position. One end of the chilled goods conveyor belt 201 extends to the picking station, and the other end extends to the chilled goods packing port at one end of the container table 400. Automated handling robots or existing automated picking equipment are used to automatically pick all chilled goods from the order information at the picking station. The picked chilled goods are then pushed onto the chilled goods conveyor belt 201 by manual or automated means. The chilled goods are then started, transporting them sequentially to the chilled goods packing port, where they fall into the insulated boxes located at position 245 below, thus achieving automatic packing of the chilled goods.

[0067] like Figure 1 As shown, the ice pack conveyor line 300 mainly includes an ice pack conveyor belt 301 and an ice pack buffer position 302. One end of the ice pack conveyor belt 301 extends to the ice pack buffer position 302, and the other end extends to the ice pack boxing opening on the other side of the container table 400. An automated handling robot transfers the ice packs from the ice pack buffer position 302 to the ice pack conveyor belt 301. Then, the ice pack conveyor belt 301 is started to transport the ice packs sequentially to the ice pack boxing opening, and they fall from the ice pack boxing opening into the insulated box at the lower workstation slot 245, realizing the automatic boxing of ice packs.

[0068] It is worth noting that, depending on the location of the chilled goods and ice packs, such as Figure 1 As shown, the empty box conveyor line 100 can be positioned in the second workstation direction, and the ice pack conveyor line 300 can be positioned in the third workstation direction. This allows for a centralized packing method where chilled goods are first loaded into the insulated box, and then ice packs are centrally loaded into the insulated box after the ice packs have been loaded. Alternatively, the positions of the empty box conveyor line 100 and the ice pack conveyor line 300 can be interchanged according to actual needs, so that ice packs are loaded into the insulated box first, and then chilled goods are centrally loaded into the insulated box after the ice packs have been loaded.

[0069] Furthermore, such as Figure 9 , Figure 10 , Figure 11 and Figure 13 As shown, to control the packing speed of chilled goods and ice packs, adjustable first baffle 207 and second baffle 303 are respectively installed at the discharge ports of the chilled goods conveyor belt 201 and the ice pack conveyor belt 301. By manually controlling the opening of the first baffle 207 to narrow, the problem of some chilled goods falling out of the box and causing missed packing can be effectively avoided by the packing speed being too fast. At the same time, the opening of the first baffle 207 can be manually controlled to widen, solving the problem that the current packing speed is too slow and cannot complete the centralized packing action within the three-quarters loop dwell time.

[0070] Similarly, by manually controlling the opening of the second baffle 303 to narrow, the problem of some ice packs falling out of the box and causing omissions can be effectively avoided by the ice pack packing speed being too fast. At the same time, the opening of the second baffle 303 can be manually controlled to widen, which solves the problem of the ice pack packing speed being too slow and not being able to complete the packing action within the three-quarters circle dwell time.

[0071] In addition, such as Figure 1 As shown, to achieve centralized loading of insulated boxes, chilled goods, and ice packs, the container platform 400 needs to be connected to the empty box conveyor line 100, the chilled goods conveyor line 200, the ice pack conveyor line 300, and the container conveyor line 500, respectively. To this end, empty box inlets, ice pack filling inlets, chilled goods filling inlets, and container discharge inlets are respectively provided on the left and right sides and at the front and rear ends of the container platform 400. In operation, insulated boxes fed into the empty box inlet are driven to rotate by external force and sequentially transferred to the chilled goods filling inlet and the ice pack filling inlet, where they remain for a period of time. After centralized loading of chilled goods and ice packs, they are transferred from the container discharge inlet to the container conveyor line 500, and then transferred to the next process for sealing.

[0072] In a preferred embodiment of this invention, for a three-dimensional cold chain warehousing system, the main equipment of the automated sorting and containerizing system, such as the containerizing platform 400, empty box conveyor line 100, chilled food conveyor line 200, ice pack conveyor line 300, and container conveyor line 500, is installed on the ground floor of the cold chain warehouse. To fully utilize the upper space of the warehouse, the picking station and chilled food buffer area are divided into two groups, including a first picking station 202, a first chilled food buffer area 203, a second picking station 204, an elevator 205, and a second chilled food buffer area 206.

[0073] Specifically, the first picking station 202, the first cold-fresh buffer position 203, the second picking station 204, the first cold-fresh buffer position 203, the container table 400, the empty box conveyor line 100, the ice pack conveyor line 300, and the container conveyor line 500 are located on the ground floor of the cold chain warehouse to facilitate the installation and maintenance of each piece of equipment. To fully utilize the upper-level space of the cold chain warehouse, the second cold-fresh buffer position 206 is located on the upper level of the cold chain warehouse to achieve automated centralized packing of cold-fresh goods stored on the upper level.

[0074] like Figure 1 As shown, on the one hand, the first cold-fresh buffer position 203 is connected to the first picking station 202 by a four-way vehicle or other handling robot. That is, the cold-fresh goods to be picked are automatically transferred to the first picking station 202 by the four-way vehicle or other handling robot. The first picking station 202 is located on one side of the middle section of the cold-fresh conveyor belt 201. The picked cold-fresh goods are transported to the insulated box by the cold-fresh conveyor belt 201.

[0075] On the other hand, a second picking station 204 is set in front of the first picking station 202. The second picking station 204 uses a four-way vehicle or other handling robot to connect to the elevator 205. The four-way vehicle or other handling robot automatically transfers the chilled goods in the upper second chilled goods buffer position 206 to the second picking station 204 via the elevator 205, and finally transports them to the insulated box via the chilled goods conveyor belt 201.

[0076] In summary, the core technical solution of this automated sorting and containerization system for cold chain logistics warehousing is to creatively connect the empty box conveyor line 100, the chilled goods conveyor line 200, the ice pack conveyor line 300, and the container conveyor line 500 to the four sides of the container platform 400. By utilizing the alternating workstation flow and dwell characteristics of the container platform 400, the system sequentially achieves the feeding of insulated boxes, the centralized packing of picked goods, the packing of ice packs, and the transfer to the next process, greatly simplifying the outbound process of cold chain logistics and improving the operational efficiency of cold chain warehousing.

[0077] Example 2 Figure 2 , Figure 3 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, this embodiment provides a container platform 400 for the automatic sorting and containerization system of cold chain logistics warehousing in Embodiment 1. The container platform 400 mainly includes a support platform 410 and a rotating containerization mechanism 420, a rotating transmission mechanism 440, a ring transmission mechanism 450, and a fixed transmission mechanism 460 concentrically arranged on the top of the support platform 410. The rotating transmission mechanism 440 sequentially realizes the power transmission with the fixed transmission mechanism 460, the ring transmission mechanism 450, and the rotating containerization mechanism 420. In the process of power transmission, the alternating station flow and stopping for box packing of the ring transmission mechanism 450 and the rotating containerization mechanism 420 are realized.

[0078] Specifically, four workstation slots 425 are equidistantly arranged around the periphery of the rotating disk 424 on the rotating container mechanism 420. The four workstation slots 425 are arranged at the four corners and their openings face outwards, for accommodating insulated boxes. A ring transmission mechanism 450 is fixedly installed above the rotating disk 424. The main power transmission technology of this container platform 400 is that the ring transmission mechanism 450 is intermittently engaged with the ring transmission mechanism 450 through an inner fixed transmission mechanism 460.

[0079] During the passive rotation of the rotary transmission mechanism 440 by 90°, the insulated box on one of the workstation slots 425 of the rotary disk 424 can rotate synchronously with the annular transmission mechanism 450 for one-quarter of a turn, thus transferring the insulated box from the previous workstation slot 425 to the next workstation slot 425. Furthermore, during the subsequent passive rotation of the rotary transmission mechanism 440 by 270°, since the rotary transmission mechanism 440 and the annular transmission mechanism 450 disengage, no power is transmitted to the annular transmission mechanism 450. Consequently, the insulated box on the workstation slot 425 remains stationary as the annular transmission mechanism 450 rotates three-quarters of a turn with the rotary transmission mechanism 440. Repeating this arrangement achieves the alternating rotation and stationary position of the rotary disk 424, facilitating workstation transfer and centralized packing.

[0080] The container platform 400 is an integrated structure assembled from a support platform 410, a rotating container mechanism 420, a rotating transmission mechanism 440, a ring transmission mechanism 450, a fixed transmission mechanism 460, and a container conveying mechanism 430. It features a novel design, compact structure, and small footprint. The entire system can operate intermittently using a single drive motor 480, simultaneously achieving the purpose of transferring and packing at each workstation. It has the advantages of high sorting and packing efficiency and saving time and effort.

[0081] As one of the preferred embodiments, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, the support platform 410 mainly includes a box body 411, a sliding door 412, and support legs 417. The box body 411 is constructed of stainless steel or aluminum alloy profiles. The sliding door 412 is made of transparent glass window. The support legs 417 are height-adjustable support legs, or brakeable wheels can be used as needed.

[0082] A circular groove 413 is provided in the middle of the top plate of the housing 411 to facilitate the installation of the rotating container mechanism 420. A set of first screw holes 414 are provided at the four corners of both ends of the top plate of the housing 411 for fixing the cover 470. Several oblique strip holes 415 and several wire holes 416 are provided on the back plate of the housing 411.

[0083] There are two sliding doors 412, which are slidably installed in the grooves of the front door frame of the container 411 to form a sliding door structure that can slide relative to each other from left to right. To facilitate the opening and closing of the sliding doors 412, handles can be installed on the sliding doors 412. To ensure the stability of the container platform 400, there are four support feet 417, which are fixedly installed at the four bottom corners of the container 411.

[0084] As one of the preferred embodiments, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the rotating container mechanism 420 includes a hollow support shaft 421, a fixed disk 423, and a rotating disk 424 arranged concentrically. The hollow tubular structure of the hollow support shaft 421 has its lower end rotatably connected to the fixed disk 423 via a first bearing 422, and its upper end is supported by a rotating transmission mechanism 440 via a second bearing 427. The rotating transmission mechanism 440 can rotate relative to the hollow support shaft 421 via the second bearing 427 without affecting each other.

[0085] The outer periphery of the fixed plate 423 is fixedly installed in the circular groove 413 on the top of the support platform 410 by welding, and the inner periphery is fixedly connected to the outer ring of the first bearing 422. The fixed plate 423 is fixedly installed through the inner and outer edges. In order not to affect the transfer and feeding of the insulation box, the fixed plate 423 is installed below the rotating plate 424.

[0086] The inner periphery of the rotating disk 424 is fixed to the lower middle position of the hollow support shaft 421, and four U-shaped opening work slots 425 are provided at equal intervals on its outer periphery. The height of the rotating disk 424 from the lower fixed disk 423 is required to be less than the height of the insulation box, so that at least part of the insulation box is limited in the work slots 425 and can be pushed by the rotating disk 424 to rotate synchronously.

[0087] Furthermore, to facilitate the fixed installation of the ring transmission mechanism 450, a plurality of second screw holes 426 for fixing the ring transmission mechanism 450 are provided at intervals on the rotating disk 424. Figure 13 As shown, there are at least four second screw holes 426 arranged at the four corners, which are used to be threadedly fixed to the support rod 452 of the upper annular transmission mechanism 450.

[0088] As one of the preferred embodiments, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the rotary transmission mechanism 440 mainly includes a transmission shaft 441, a synchronous pulley 442, and a sector-shaped gear disk 443, which are assembled into a single structure.

[0089] The drive shaft 441 is rotatably mounted inside the hollow support shaft 421 of the rotating container mechanism 420. Its lower end is connected to the drive motor 480 via a fixed synchronous pulley 442, and its upper end is fixedly connected to a sector-shaped gear disk 443. The drive motor 480 can synchronously drive the drive shaft 441 to rotate, which in turn synchronously drives the sector-shaped gear disk 443 at the upper end to rotate.

[0090] Of particular note is that, in order to achieve the purpose of alternating power transmission between the annular transmission mechanism 450 and the rotating container mechanism 420, the sector-shaped gear disk 443 adopts a special figure-eight sector gear structure, with external transmission racks 444 respectively provided on the outer peripheral walls of the sector structures at both ends. Moreover, the angle of the external transmission racks 444 is 90°, and they are intermittently meshed with the fixed transmission mechanism 460 during rotation.

[0091] Specifically, within the 90° rotation range in contact with the fixed transmission mechanism 460, power can be transmitted through the fixed transmission mechanism 460, thereby synchronously driving the annular transmission mechanism 450 and the rotating container mechanism 420 to rotate. At this time, the rotating container mechanism 420 is in a stationary circulation state. Within the remaining 270° rotation range after disengaging from the fixed transmission mechanism 460, the annular transmission mechanism 450 and the rotating container mechanism 420 are not driven by external forces and are therefore in a relatively static centralized packing state.

[0092] By employing a figure-eight-shaped sector gear structure, the sector gear 443 and the fixed transmission gear 460 positioned at a fixed point on the outer side achieve intermittent meshing connection between the sector gear 443 and the ring gear 450. The angle of the sector gear is designed to be 90°, so that when the sector gear rotates one revolution, its quarter revolution synchronously drives the rotating disk and the insulation box on the work station slot to rotate, thus facilitating the flow of the work station. When it rotates three-quarters of a revolution, it disengages from the fixed transmission gear and is in a stationary state, which makes it convenient to put the insulation box, goods or ice packs into the corresponding work station, thereby alternately achieving the purpose of work station rotation and material feeding.

[0093] As one of the preferred embodiments, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13As shown, the annular transmission mechanism 450 mainly includes an annular gear disk 451 and four spaced-apart support rods 452. To achieve power transmission between the annular gear disk 451 and the fixed transmission mechanism 460, the annular gear disk 451 is a hollow annular structure, and an inner transmission rack 453 is provided on the inner circumferential wall of the annular gear disk 451. Power transmission is established by the meshing connection between the inner transmission rack 453 and the inner fixed transmission mechanism 460.

[0094] To connect the annular transmission mechanism 450 with the rotating container mechanism 420, the top ends of the four support rods 452 are threaded to a number of third screw holes 454 spaced apart on the annular gear plate 451, and the lower ends are threaded to a number of second screw holes 426 on the annular transmission mechanism 450.

[0095] As one of the preferred embodiments, such as Figure 2 , Figure 3 , Figure 5 , Figure 16 and Figure 17 As shown, the fixed transmission mechanism 460 includes two sets of apex gear transmission mechanisms arranged symmetrically on the left and right, consisting of a fixed transmission gear 461, a pin 462, and a support plate 463.

[0096] Specifically, the inner side of the fixed transmission gear 461 is intermittently meshed with the sector-shaped gear disk 443 on the rotary transmission mechanism 440, and the outer side is meshed with the inner transmission rack 453 on the inner side of the annular transmission mechanism 450. The lower end of the pin 462 is rotatably fitted with the fixed transmission gear 461, and the upper end is fixedly connected to the support plate 463, which is fixed to the top position of the cover 470.

[0097] As one of the preferred embodiments, such as Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 16 and Figure 17 As shown, the container platform 400 also includes a container conveying mechanism 430 disposed on the top of the fixed plate 423 and a cover 470 disposed on the top of the support platform 410.

[0098] The container conveying mechanism 430 consists of a first conveying roller 431, a second conveying roller 432, and a third conveying roller 433 connected in sequence. The second conveying roller 432 has a three-quarter arc shape, extending in an arc from the empty box inlet to the container outlet. The first conveying roller 431 and the third conveying roller 433 are located at the empty box inlet and the container outlet, respectively. That is, the container conveying mechanism 430 is laid along the transfer path of the insulated box, ensuring the accuracy of the transfer direction of the insulated box and avoiding problems such as deviation or jamming.

[0099] To ensure that the insulated box after packing can be transferred from the end of the second conveying roller 432 to the input end of the third conveying roller 433 under the push of the rotating disk 424, a guide roller (434) is provided at the outer connection of the second conveying roller 432 and the third conveying roller 433. The guide roller (434) is arranged in an arc shape, with one end located on the outer side of the end of the second conveying roller 432 and the other end extending in an arc to the third conveying roller 433, so as to guide the insulated box conveyed to the corner connection into the third conveying roller 433, avoid the insulated box getting stuck at the corner, and effectively ensure the smooth transfer of the insulated box.

[0100] Furthermore, since the top of the insulated box is confined within the work station slot 425, the thrust of the rotating container mechanism 420 can be used to indirectly realize the automatic transfer and discharge of the insulated box at different work stations. Moreover, the container conveying mechanism 430, which adopts a roller-type structure design, greatly facilitates the transfer and connection with the empty box conveying line 100, the chilled food conveying line 200, the ice pack conveying line 300, and the container conveying line 500, ensuring the stability and speed of the insulated box transfer.

[0101] Corresponding to the above, square openings 471 are respectively provided on the left and right sides and front and rear ends of the cover 470 to form empty box inlet, ice pack inlet, chilled fresh box inlet and container outlet. The insulated box input from the empty box inlet flows through the chilled fresh box inlet and ice pack inlet in sequence and then exits from the container outlet to the container conveyor line 500.

[0102] As needed, a dust removal fan 475 is installed on the top of the enclosure 470. The dust removal fan 475 introduces dust-free and sterile air into the enclosure, keeping the inside of the enclosure 470 in a slightly positive pressure environment at all times. This prevents external space from entering the enclosure and contaminating the insulated boxes, chilled goods, and ice packs during transfer.

[0103] In addition, to facilitate the installation and fixation of the cover 470, ear plates 472 are respectively provided on the open sides at both the front and rear ends of the cover 470. Mounting holes 473 are provided on the ear plates 472, such as... Figure 16 and Figure 17As shown. Fastening screws 474 are screwed through mounting holes 473 and tightened into the first screw hole 414 on the top of the support platform 410.

[0104] As one of the preferred embodiments, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 12 As shown, the rotating container mechanism 420 is designed to provide driving force for automated drive and control. The container platform 400 also includes a drive motor 480 and a controller 490.

[0105] The drive motor 480 is vertically mounted inside the housing 411 of the support platform 410 and is fixed to the base plate of the housing 411 with bolts. The output shaft at the top of the drive motor 480 is then connected to the synchronous pulley 442 at the lower end of the rotary transmission mechanism 440 via a synchronous belt 481. When the drive motor 480 is started, the synchronous pulley 442 rotates synchronously via the synchronous belt 481, and then intermittent transmission is achieved through the sector gear plate 443, the fixed transmission mechanism 460, the ring transmission mechanism 450, and the rotating disk 424.

[0106] The controller 490 is controlled by a PLC and is screwed to the top of the cover 470. It is electrically connected to the drive motor 480, the empty box conveyor belt 101, the chilled food conveyor belt 201, the ice pack conveyor belt 301, and the container conveyor belt 501 on the container conveyor line 500, and is used to control the operation of the drive motor 480 and each conveyor belt.
