Description

Technical Field

[0001] The invention relates to the technical field of screen printing equipment, and in particular to a double-platform shuttle printing machine and a printing method. Background Art

[0002] Screen printing is also known as "silk screen printing". During printing, the ink is transferred to the substrate through the mesh of the image part through the extrusion of the scraper, forming the same image as the original. Screen printing is widely used because of its simple equipment, convenient operation, simple printing and plate making, low cost, and strong adaptability.

[0003] The shuttle screen printing machine in the related technology includes single-platform (single direction) and double-platform printing methods. The single-platform printing method has low processing efficiency and cannot meet the needs of high-speed printing. The double-platform (two-way loading) printing method requires pausing and waiting in one direction when printing in the other direction. The existing double-platform printing machine does not optimize the printing process for the paused and waiting side, thereby wasting a lot of waiting time, thereby reducing printing efficiency and increasing printing costs.

The carrier plate carrying the second printed product, and the received carrier plate is transferred to the double printing mechanism and shuttled between the two printing components of the double printing mechanism, wherein the first printed product is a printed product that has been printed, and the second printed product is a product to be printed; the oven mechanism is used to bake the first printed product placed on the corresponding carrier plate; the synchronous loading and unloading mechanism of the stacking stack is used to flexibly dock with the shuttle conveying mechanism placed in the corresponding oven mechanism, and after receiving the carrier plate carrying the third printed product, the carrier plate carrying the second printed product is pushed to the shuttle conveying mechanism located in the oven mechanism, so that the corresponding shuttle conveying mechanism transfers the carrier plate carrying the second printed product to the double printing mechanism, and the third printed product is a printed product that has been baked.

[0007] In a second aspect, the present invention further provides a technical solution as follows: a printing method, comprising the dual-platform shuttle printing machine of the first aspect, the printing method comprising the following steps: Step S1, one of the shuttle conveying mechanisms, while another of the shuttle conveying mechanisms conveys the carrier plate carrying the first printed product to one of the two oven mechanisms for baking, conveys the carrier plate carrying the third printed product corresponding to the previous printing to the corresponding one of the stacking synchronous loading and unloading mechanisms at the docking position with the corresponding one of the oven mechanisms, receives the carrier plate carrying the second printed product pushed by the one of the stacking synchronous loading and unloading mechanisms, and conveys the received carrier plate to the double printing mechanisms; Step S2, one of the shuttle transmission mechanisms transmits the corresponding carrier plate to drive a plurality of second printed products to be placed under the two printing components in sequence, so that the two printing components perform two-time printing or two-color printing on each second printed product in sequence; Step S3, after the two printing components complete printing of all the second printed products and obtain the first printed products, one of the shuttle conveyor mechanisms conveys the corresponding carrier plate to drive the plurality of first printed products to shuttle back to the corresponding oven mechanism for baking, and the other shuttle conveyor mechanism located in the corresponding oven mechanism, after completing conveying the carrier plate carrying the third printed product to the other stacking synchronous loading and unloading mechanism, receives the carrier plate carrying the second printed product pushed by the other stacking synchronous loading and unloading mechanism, and conveys the received carrier plate to the double printing mechanism for printing; Step S4: the shuttle transmission mechanism, the oven mechanism and the synchronous loading and unloading mechanism for stacking located on both sides of the double printing mechanism cooperate with the double printing mechanism to repeat the operations of steps S1 to S3 until the preset number of printings is completed.

The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0014] See also Figures 1 to 9 The double-platform shuttle printing machine of the embodiment of the present application comprises a double printing mechanism 200, a shuttle transmission mechanism 300 and an oven mechanism 400 arranged on a horizontally extending frame 100. An oven mechanism 400 is arranged at both horizontal ends of the frame 100. A shuttle transmission mechanism 300 is arranged between each oven mechanism 400 and the double printing mechanism 200. A stacking synchronous loading and unloading mechanism 500 is arranged on the other side of each oven mechanism 400 away from the shuttle transmission mechanism 300, and is movably docked with the shuttle transmission mechanism 300 that shuttles into the corresponding oven mechanism 400. The shuttle conveying mechanism 300 is at least used to receive the carrier plate 600 carrying the second printed product at the corresponding oven mechanism 400 during the process of transferring the carrier plate 600 carrying the first printed product to one of the two oven mechanisms 400 for baking in another shuttle conveying mechanism 300, and transfer the received carrier plate 600 to the double printing mechanism 200, and shuttle transfer between the two printing components 21 of the double printing mechanism 200, wherein the first printed product is a printed product that has been printed, and the second printed product is a product to be printed.

[0015] In this embodiment, when printing starts, one of the two shuttle conveyor mechanisms 300 needs to transport the carrier plate 600 carrying the second printed product loaded from the stacking synchronous loading and unloading mechanism 500 to the double printing mechanism 200, and then the shuttle conveyor mechanism 300 carries the carrier plate 600 carrying multiple second printed products and places them under the two printing components 21 in sequence, and the two printing components 21 print each second printed product in sequence. After printing is completed, the shuttle conveyor mechanism 300 will shuttle the carrier plate 200 carrying the printed product (corresponding to the first printed product) back to the position for receiving the printed product, that is, back to the oven mechanism 400, so as to At least the printed product is baked; after the first operation, while a shuttle conveyor mechanism 300 is conveying a second printed product to the dual printing mechanism 200 for printing, another shuttle conveyor mechanism 300 will convey the first printed product of the previous printing to the corresponding oven mechanism 400 for baking, and after the baking is completed, it will take over a new second printed product to be printed, so that when the second printed product conveyed by the one shuttle conveyor mechanism 300 is printed and conveyed to the corresponding oven mechanism 400 for baking, the other shuttle conveyor mechanism 300 can carry the new second printed product to be printed to the dual printing mechanism 200 for printing.

[0016] It can be understood that in this embodiment, two shuttle conveying mechanisms 300 are used to cyclically and alternately convey the second printed product to the double printing mechanism 200 for printing, and to convey the printed first printed product back to the corresponding oven mechanism 400 for baking. In this way, a cyclic printing operation is performed to realize a double-platform printing operation. At the same time, the waiting time for printing caused by baking the printed products is reduced, thereby improving printing efficiency.

[0017] The oven mechanism 400 is used to bake the first printed product placed on the corresponding carrier plate 600 .

[0018] In the present embodiment, the oven mechanism 400 includes but is not limited to a mini tunnel oven, and the oven mechanism 400 is nested with the frame 100, the cavity of the oven mechanism 400 constitutes a part of the channel for the shuttle conveyor mechanism 300 to drive the corresponding carrier plate 600 to move, and the oven mechanism 400 uses wind heat drying to dry the first printed product. When the shuttle conveyor mechanism 300 conveys the corresponding carrier plate 600 into the oven mechanism 400 and is placed in a docking position with the stacking synchronous loading and unloading mechanism 500, the carrier plate 600 is also located in the corresponding baking area, thereby drying the first printed product; it should be understood that in the present embodiment, in order to ensure that the dual-platform cycle uninterrupted printing can be achieved, the oven mechanism 400 is for the first printed product. The printing time of one printed product is matched with the time when another shuttle transmission mechanism 300 drives the corresponding carrier plate 600 to drive all the second printed products to shuttle to the double printing mechanism 200, and the two printing components 21 sequentially perform two-time or two-color printing on all the second printed products. That is, when the printed product on one lateral side of the frame 100 is printed at the double printing mechanism 200, the printed product on the other lateral side of the frame 100 has at least been dried and unloaded to the corresponding stacking synchronous loading and unloading mechanism 500, and the loading of the new second printed product to be printed is completed. Then, when the printed product that has been printed is transmitted to the corresponding oven mechanism 400, the new product to be printed on the other side is transmitted to the double printing mechanism 200 for printing.

[0019] The synchronous loading and unloading mechanism 500 for stacking is used for movably docking with the shuttle conveyor mechanism 300 placed in the corresponding oven mechanism 400, and after receiving the carrier plate 600 carrying the third printed product, pushes the carrier plate 600 carrying the second printed product to the shuttle conveyor mechanism 300 located in the oven mechanism 400, so that the corresponding shuttle conveyor mechanism 300 transfers the carrier plate 600 carrying the second printed product to the double printing mechanism 200, and the third printed product is the printed product that has been baked.

[0020] In this embodiment, the conveyor arranged in the synchronous loading and unloading mechanism 500 for stacking is stacked up and down and corresponds to the storage layer 511 on its turnover shelf 51. The upper and lower storage layers 511 are also respectively defined as storage layers 511 for placing different printed products, thereby ensuring that each conveyor corresponds to one storage layer 511, and realizes synchronous unloading of the carrier 600 carrying the third printed product to the synchronous loading and unloading mechanism 500 for stacking and loading and loading of the carrier 600 carrying the second printed product to the corresponding conveyor, and then after receiving the carrier 600 carrying the third printed product, the carrier 600 carrying the second printed product is transferred to the shuttle conveying mechanism 300. In this way, synchronous loading and unloading is achieved, and the double platforms are maintained for shuttle feeding, printing and returning of materials, and baking. Circular operation.

[0021] It is understandable that in order to meet the requirements of multiple printing operations, the turnover shelves 51 of the synchronous loading and unloading mechanisms 500 of the stacks arranged on the horizontal sides of the frame 100 can also be arranged to be able to circulate with each other, that is, when the printed product located on the left side of the double printing mechanism 200 completes one printing, it is transferred to the right side through the mutual circulation of the turnover shelves 51, and then printed once, thereby realizing the printing of printed products that need multiple printing needs; it is also understandable that after the printing of the printed product on one side is completed, the printed product that has been printed once before is reloaded from the synchronous loading and unloading mechanism 500 of the stack, and then printed again, so as to meet the printing needs of printed products that need multiple printing needs.

[0022] In the above-mentioned double-platform shuttle printing machine, a carrier plate 600 carrying a first printed product is transferred to one of the two oven mechanisms 400 by a shuttle conveying mechanism 300 and baked in another shuttle conveying mechanism 300, and a carrier plate 600 carrying a second printed product is received at a corresponding oven mechanism 400, and the received carrier plate 600 is transferred to the double printing mechanism 200 and shuttled between the two printing components 21 of the double printing mechanism 200; the first printed product on the corresponding carrier plate 600 is transferred by the oven mechanism 400 to the second printing component 21 of the double printing mechanism 200; The printed products are baked; and after receiving the carrier plate 600 carrying the third printed product through the stacking synchronous loading and unloading mechanism 500, the carrier plate 600 carrying the second printed product is pushed to the shuttle conveying mechanism 300 located in the oven mechanism 400, so that the corresponding shuttle conveying mechanism 300 conveys the carrier plate 600 carrying the second printed product to the double printing mechanism 200, so as to realize the synchronous cycle of the double platforms to carry out printing, conveying, baking, unloading and loading operations uninterruptedly, improve the printing efficiency, and solve the problem of low printing efficiency of the shuttle screen printing machine in the related technology.

[0023] In order to realize the transfer of the carrier plate 600 carrying different printed products between the synchronous loading and unloading mechanism 500 and the shuttle transmission mechanism 300, refer to Figures 1 to 6 In some embodiments, the shuttle transmission mechanism 300 includes a lifting unit 31, a material conveying unit 32 and a shuttle feeding assembly 33. The lifting unit 31 is installed on a lateral side of the frame 100 and is used to drive the material conveying unit 32 connected thereto to move vertically. The shuttle feeding assembly 33 is movably arranged on the frame 100. After the lifting unit 31 drives the loading and conveying unit 32 to move vertically and lifts the carrier 600 carrying the first printed product from the shuttle feeding assembly 33, the loading and conveying unit 32 transmits the corresponding carrier 600 laterally to the docking position with the synchronous loading and unloading mechanism 500 of the stacking stack; the loading and conveying unit 32 is also used to receive the carrier 600 carrying the second printed product laterally loaded by the synchronous loading and unloading mechanism 500 of the stacking stack, and then transmit the corresponding carrier 600 laterally to the position directly above the shuttle feeding assembly 33, and place the carrier 600 carrying the second printed product on the shuttle feeding assembly 33 while being driven by the lifting unit 31 to move vertically downward.

[0024] In the present embodiment, the loading and conveying unit 32 is lower than the position of the carrier plate 600 placed on the corresponding shuttle feeding assembly 33 when in the initial position, and the loading and conveying unit 32 is a loading and conveying unit with a hollow middle, that is, when the loading and conveying unit 32 moves vertically up and down, it will not be blocked by the shuttle feeding assembly 33. When the loading and conveying unit 32 is placed in a position lower than the shuttle feeding assembly 33, the loading and conveying unit 32 moves vertically upward to support the carrier plate 600 located on the shuttle feeding assembly 32. When the loading and conveying unit 32 is placed in a position higher than the shuttle feeding assembly 33, the loading and conveying unit 32 moves vertically downward to place the supported carrier plate 600 on the shuttle feeding assembly. 32; in the present embodiment, when it is necessary to transfer the carrier plate 600 carrying the first printed product to the synchronous loading and unloading mechanism 500 for stacking, the lifting unit 31 will drive the material conveying unit 32 to move vertically upward, and lift up the carrier plate 600 located on the shuttle feeding assembly 32, and cooperate with its own lateral transmission to transport the corresponding carrier plate 600 to the synchronous loading and unloading mechanism 500 for stacking; when the material conveying unit 32 receives the corresponding carrier plate 300 loaded from the synchronous loading and unloading mechanism 500 for stacking, the lifting unit 31 will drive the material conveying unit 32 to move vertically downward, and lift up the carrier plate 600 located on the shuttle feeding assembly 32, so that the carrier plate 600 carrying the second printed product is placed on the shuttle feeding assembly 33.

[0025] The shuttle feeding assembly 33 is used to shuttle the carrier 600 carrying the second printed product through the two printing assemblies 21, so that the printing assemblies 21 can print the second printed product on the carrier 600 in turn, and return the carrier 600 carrying the first printed product from the double printing mechanism 200 to the corresponding material conveying unit 32.

[0026] In this embodiment, as a transport component, it is used to transport the carrier 600 carrying multiple second printed products to the double printing mechanism 200, and after all the second printed products on the carrier 600 are printed, the carrier 600 and the multiple corresponding first printed products are returned to the corresponding oven mechanism 400, which is also the docking position with the stacking synchronous loading and unloading mechanism 500.

[0027] It can be understood that, with such an arrangement, the lifting unit 31 is used to drive the loading and conveying unit 32 to move vertically, and cooperate with the lateral transmission of the loading and conveying unit 32, so as to realize the transfer of the carrier 600 carrying different printed products to the synchronous loading and unloading mechanism 500 of the stacking stack or place it on the shuttle feeding component 33; through the transportation of the shuttle feeding component 33, the printed products are transported to the dual printing mechanism 200 and corresponding printing is carried out. While realizing the transmission of the carrier 600 carrying different printed products between the synchronous loading and unloading mechanism 500 of the stacking stack and the shuttle transmission mechanism 300, it also assists the dual printing mechanism 200 to print.

[0028] In some of these embodiments, reference Figures 1 to 6 The lifting unit 31 includes a bottom plate 311, a guide column 312, a lifting drive unit 313 and a U-shaped bracket 314. The material conveying unit 32 includes a synchronous transmission belt 321, a V-shaped seat 322 and a synchronous drive unit 323. The bottom plate 311 is fixed on the frame 100. The U-shaped bracket 314 is movably connected to the bottom plate 311 through the guide column 312. The U-shaped bracket 314 is also connected to the lifting drive unit 313 fixed on the bottom plate 311. The two side walls of the U-shaped bracket 314 are provided with synchronous transmission belts 321. Each synchronous transmission belt 321 is fixed with a plurality of V-shaped seats 322. The two synchronous transmission belts 321 are connected to the synchronous drive unit 323. The lifting drive unit 313 is used to drive the U-shaped bracket 314 to drive the loading and conveying unit 32 to move vertically, so that the loading and conveying unit 32 lifts the carrier 600 carrying the first printed product from the shuttle feeding assembly 33 or places the carrier 600 carrying the second printed product on the shuttle feeding assembly 33.

[0029] In this embodiment, the lifting drive unit 313 includes but is not limited to one of the following: a driving cylinder, a ball screw module, and an electric cylinder. In this embodiment, the lifting drive unit 313 provides power to enable the loading and conveying unit 32 to move vertically.

[0030] The synchronous drive unit 323 is used to drive the two synchronous transmission belts 321 to synchronously drive the corresponding multiple V-shaped seats 322 to rotate, and drive the carrier 600 supported by the V-shaped seat 322 to move horizontally to the shuttle feeding assembly 33 located in the U-shaped groove of the U-shaped bracket 314, or to remove the carrier 600 located on the shuttle feeding assembly 33.

[0031] In this embodiment, the synchronous drive unit 323 includes but is not limited to a servo motor; in this embodiment, a plurality of V-shaped seats 322 are fixed to the synchronous transmission belt 321. When two synchronous transmission belts 321 synchronously drive the corresponding plurality of V-shaped seats 322 to perform cyclic rotation, the V-shaped seats 322 located on the horizontal plane will first move horizontally until they move to the front and rear ends of the synchronous transmission belt 321, and then rotate. The carrier plate 600 is stuck on the V-shaped seat 322. When the V-shaped seat 322 moves horizontally, it will drive the carrier plate 600 to move horizontally. When the corresponding V When the V-shaped seat 322 needs to be rotated, the carrier plate 600 will continue to move horizontally due to the drive of other V-shaped seats 322 in the horizontal plane, or when the V-shaped seat 322 needs to be rotated, the carrier plate 600 has been partially received by the shuttle feeding assembly 33 or the synchronous loading and unloading mechanism 500 of the stacking stack, and under the push of the V-shaped seat 322 located behind the V-shaped seat 322 that needs to be rotated, the carrier plate 600 can continue to move horizontally until it is completely placed on the shuttle feeding assembly 33 or the synchronous loading and unloading mechanism 500 of the stacking stack, so as to realize the horizontal transmission of the carrier plate 600.

[0032] To realize the transfer of the carrier plate 600 between the double printing mechanism 200 and the oven mechanism 400, refer to Figures 1 to 6 In some embodiments, the shuttle feeding assembly 33 includes a linear guide rail 34, a sliding table 35, a vacuum suction plate 36, a positioning assembly 37 and a linear motor 38. Two linear guide rails 34 extending along the length direction of the frame 100 are provided on both sides of the width direction of the frame 100. The linear guide rails 34 are also located on the longitudinal outer sides of the two synchronous transmission belts 321 in the setting position. The sliding table 35 is movably connected with the two linear guide rails 34 and is transmission-connected with the linear motor 38 installed on the frame 100. The vacuum suction plate 36 is arranged on the sliding table 35. The positioning assembly 37 is installed on the sliding table 35 and distributed around the vacuum suction plate 36. After the carrier 600 carrying the second printed product is placed on the vacuum suction plate 36 by the material conveying unit 32 , the positioning assembly 37 is used to perform lateral and longitudinal alignment on the carrier 600 so as to place the carrier 600 at a preset position.

[0033] The vacuum suction plate 36 is used to absorb and fix the corresponding carrier 600 after the carrier 600 carrying the second printed product is calibrated to a preset position, and to release the corresponding carrier 600 after the shuttle feeding component 33 returns the carrier 600 carrying the first printed product to dock with the corresponding carrier conveying unit 32.

[0034] The linear motor 38 is used to drive the sliding table 35 to drive the vacuum suction plate 36 and the positioning assembly 37 to move between the docking position with the material conveying unit 32 and the docking position with the double printing mechanism 200, so as to shuttle the carrier 600 carrying the second printed product through the two printing components 21 and return the carrier 600 carrying the first printed product to the corresponding material conveying unit 32.

[0035] In this embodiment, the linear motor 38 is an electromagnetic induction linear motor.

[0036] In some embodiments, the positioning assembly 37 includes a limit column 371, a longitudinal push calibration unit 372 and a transverse push calibration unit 373. A limit column 371 and a longitudinal push calibration unit 372 are provided at a vertex on both sides of the sliding platform 35. A transverse push calibration unit 373 is fixed on both sides of the sliding platform 35. The longitudinal push calibration unit 372 and the transverse push calibration unit 373 both include a driving cylinder 374 and a calibration seat 375. The two limiting posts 371 are used to be inserted into the limiting holes 61 of the carrier plate 600 when the corresponding carrier plate 600 is placed on the vacuum suction plate 36 , so as to initially position the carrier plate 600 .

[0037] The driving cylinders 374 of the longitudinal push calibration unit 372 and the transverse push calibration unit 373 respectively drive the corresponding calibration seats 375 to move along the corresponding directions, so as to drive the corresponding carrier plate 600 to perform transverse and / or longitudinal fine adjustment relative to the limiting column 371 until it moves to the preset position.

[0038] In this embodiment, when the carrier 600 is placed on the vacuum suction plate 36, the limiting hole 61 of the carrier 600 is inserted into the two limiting columns 371. At this time, the carrier 600 is initially limited and fixed, but a certain gap is still provided on the limiting hole 61 and the limiting column 371. At this time, the driving cylinders 374 of the longitudinal push correction unit 372 and the transverse push correction unit 373 respectively drive the corresponding correction seat 375 to push the carrier 600 to move, so that the carrier 600 is close to the limiting column 371 in the longitudinal direction and the transverse direction. In this way, it means that the transverse and / or longitudinal fine adjustment of the carrier 600 is completed, that is, the carrier 600 is adjusted to the preset position; after the positioning of the carrier 600 is completed, when the carrier 600 is conveyed to the set position below the printing component 21 (the position check can be performed by setting the corresponding photoelectric sensor), the corresponding printed product is placed at the preset printing position, so that the printed product can be accurately printed by the printing component 21.

[0039] In order to load the second printed product to be printed onto the shuttle transmission mechanism 300 located in the oven mechanism 400 or to receive the carrier plate 600 carrying the third printed product, refer to Figure 1 , Figure 2 and Fig. 9In some embodiments, the synchronous loading and unloading mechanism 500 for stacking includes a turnover shelf 51 and a stacking conveyor 52. The stacking conveyor 52 includes a lifting transmission assembly 54 arranged on the side wall of a chassis 53. The lifting transmission assembly 54 is connected to an upper conveyor 55 and a lower conveyor 56 arranged in a stacked manner. The upper conveyor 55 and the lower conveyor 56 are both arranged to face the shuttle transmission mechanism 300 and the turnover shelf 51. In this embodiment, the turnover shelf 51 is provided with multiple storage layers, and the upper and lower layers are respectively defined as storage layers for placing different printed products, that is, the upper and lower storage layers are cross-arranged, and when the storage layer of the lower layer is set as a storage layer for placing the carrier 600 carrying the second printed product (the product to be printed), the storage layer of the upper layer is set as a storage layer for placing the carrier 600 carrying the third printed product (the printed product that has been dried), so that the upper conveyor 55 and the lower conveyor 56 are connected to different storage layers, and the carriers 600 carrying different printed products are loaded (the carrier 600 carrying the second printed product is transferred to the shuttle conveyor mechanism 300) or unloaded (the carrier 600 carrying the third printed product is transferred from the shuttle conveyor mechanism 300). In this way, loading and unloading are carried out synchronously, and the double platforms are kept to perform the cyclic operation of conveying, printing, returning and baking.

[0040] After the oven mechanism 400 bakes the first printed product into the third printed product, the lifting transmission assembly 54 drives the upper conveyor 55 and the lower conveyor 56 to move vertically, so that the lower conveyor 56 and the upper conveyor 55 are movably docked with the shuttle transmission mechanism 300 in sequence.

[0042] The lower conveyor 56, when being driven to dock with the shuttle transmission mechanism 300, receives the carrier plate 600 carrying the third printed product pushed by the corresponding shuttle transmission mechanism 300, and when it is flush with the corresponding storage layer 511 of the turnover shelf 51, transfers the carrier plate 600 carrying the third printed product to the corresponding storage layer 511.

[0043] The upper conveyor 55, when being driven to dock with the shuttle conveyor mechanism 300, transfers the carrier plate 600 carrying the second printed product to the shuttle conveyor mechanism 300 located in the corresponding oven mechanism 400, and before being transferred to dock with the shuttle conveyor mechanism 300, receives the carrier plate 600 carrying the second printed product loaded from the corresponding storage layer 511.

[0044] In this embodiment, the lifting transmission assembly 54 synchronously drives the upper conveyor 55 and the lower conveyor 56 to move, and when the lower conveyor 56 is docked with the shuttle transmission mechanism 300, the upper conveyor 55 is docked with the corresponding storage layer 511. Similarly, when the upper conveyor 55 is docked with the shuttle transmission mechanism 300, the lower conveyor 56 remains docked with another storage layer 511, thereby realizing synchronous unloading of the carrier plate 600 carrying the third printed product to the turnover shelf 51 and loading of the carrier plate 600 carrying the second printed product onto the upper conveyor 55, and after the lower conveyor 56 receives the carrier plate 600 carrying the third printed product, the upper conveyor 55 is then loaded. It is capable of transferring the carrier 600 carrying the second printed product to the shuttle transport mechanism 300; it can be understood that the upper conveyor 55 receives the carrier 600 carrying the second printed product, and it can be that the lower conveyor 56 receives the carrier 600 carrying the third printed product pushed by the corresponding shuttle transport mechanism 300. At this time, there is a corresponding carrier 600 on the storage layer 511 corresponding to the upper conveyor 55, or it can be that the lower conveyor 56 is flush with the storage layer 511 corresponding to the turnover shelf 51 and transfers the carrier 600 carrying the third printed product to the corresponding storage layer 511, but at least before the upper conveyor 55 is transferred to dock with the shuttle transport mechanism 300.
