[0040] Embodiment 1

[0041] refer to Figures 1 to 3In one embodiment of the present application, a material transportation system is disclosed, including a first line-changing component 1, a second line-changing component 2, and a plurality of material conveying lines 3, one end of the material conveying line 3 is connected to the first line-changing component 1, and the other end is connected to the second line-changing component 2. The first line-changing component 1 and the second line-changing component 2 have a bidirectional transmission function, which is used to transfer materials on any material conveying line 3 to any other material conveying line 3, thereby forming a serial transmission state and a parallel transmission state.

[0042] In some embodiments, the material conveying line 3 may adopt a conveying device that also has a bidirectional transmission function; in other embodiments, the material conveying line 3 may adopt a conveying device that has a unidirectional transmission function.

[0043] Furthermore, the material conveying line 3 has a first conveying direction from the first line changing component 1 to the second line changing component 2, and a second conveying direction from the second line changing component 2 to the first line changing component 1. And there is at least one material conveying line 3 conveying along the first conveying direction, and one material conveying line 3 conveying along the second conveying direction.

[0044] In some embodiments, the number of material conveying lines 3 is at least three. When the present application is in a parallel transmission state, a material conveying line 3 moving along a first conveying direction and a plurality of material conveying lines 3 moving along a second conveying direction form a plurality of parallel conveying loops, which are used to cope with a condition where one of the material conveying lines 3 needs to be replaced or repaired. Similarly, more similar conditions requiring shutdown can be dealt with by increasing the number of material conveying lines 3 moving along the first conveying direction and the number of material conveying lines 3 moving along the second conveying direction.

[0045] refer to Figure 1 , is a parallel transmission state of an implementation method, in which a material conveying line 3 moving along the first conveying direction and two material conveying lines 3 moving along the second conveying direction form a transmission loop with two partially overlapping routes. Figure 2 As shown, when one of the material conveying lines 3 moving along the second conveying direction needs to be shut down for a changeover, the other material conveying line 3 moving along the second conveying direction ensures that the transmission state is still operating normally.

[0046] In some embodiments, the number of material conveying lines 3 is at least three. When the present application is in a serial transmission state (such as Figure 3 As shown in FIG. 1 , the first line changing component 1 cooperates with the second line changing component 2 to transport the material alternately along the first conveying direction and along the second conveying direction on the material conveying line 3. That is, it can be understood that multiple material conveying lines 3 in different directions are connected in series in sequence to extend the transmission distance and increase the number of stations along the way, which are used for different conditions such as reprocessing of materials during transmission, increase or decrease of transmitted items, etc.

[0047] Embodiment 2

[0048] refer to Figures 4 to 9 In combination with the above-mentioned embodiment 1, the present application also discloses a conveying device with the material transportation system in the above-mentioned embodiment 1, which is used to transport a carrier 4, and the carrier 4 is used to place and transport materials.

[0049] In this embodiment, the conveying device is composed of two line-changing devices 5 and at least one conveying device 6, and any two conveying devices 6 can be connected to each other, so that the length of the conveying line on the conveying device can be controlled by changing the number of conveying devices 6.

[0050] It should be noted that the two line-changing devices 5 in this embodiment correspond to the first line-changing assembly 1 and the second line-changing assembly 2 disclosed in the first embodiment, respectively, and the material conveying line 3 is located on the conveying device 6. The line-changing device 5 is arranged at both ends of one conveying device 6 or multiple conveying devices 6 connected in series, and is used to cooperate with the conveying device 6 to form a complete transportation loop.

[0051] refer to Figure 4 In some embodiments, the conveying device 6 includes a machine platform 7, on which a first conveying line 61, a second conveying line 62, and a third conveying line 63 corresponding to the material conveying line 3 are installed. Figure 5 As shown, the first conveyor line 61 , the second conveyor line 62 , and the third conveyor line 63 are arranged side by side, and the movement direction of the second conveyor line 62 is opposite to that of the first conveyor line 61 and the third conveyor line 63 .

[0052] Furthermore, the first conveyor line 61, the second conveyor line 62, and the third conveyor line 63 are all provided with a guide mechanism and a transmission mechanism acting on the carrier 4. The guide mechanism is used to guide the moving direction of the carrier 4, and the transmission mechanism provides power for the carrier 4 along the moving direction.

[0053] In some embodiments, the guide mechanism can guide the moving direction of the carrier 4 by means of a guide rail 64 cooperating with a slider 41 , wherein the carrier 4 is provided with a slider 41 cooperating with the guide rail 64 .

[0054] In some embodiments, electromagnetic transmission or conveyor belt transmission is adopted between the transmission mechanism and the carrier 4 .

[0055] Furthermore, electromagnetic transmission is adopted between the first conveying line 61, the third conveying line 63 and the carrier 4, and conveyor belt transmission is adopted between the second conveying line 62 and the carrier 4. Figure 5 As shown.

[0056] refer to Figure 6 and Figure 7When the transmission mechanism adopts electromagnetic transmission, the transmission mechanism is composed of several electromagnetic modules 8 connected in series. The electromagnetic module 8 includes a base 81 for bearing and a coil 82 and a coil clamp 83 located on the base 81. The base 81 is connected to the machine 7, and the coil clamp 83 is connected to the base 81 and fixes the coil 82.

[0057] Furthermore, the guide rail 64 is disposed on the base 81 .

[0058] A slider 41 cooperating with the guide rail 64 is disposed on one side of the carrier 4 , and a pressing block 42 is disposed on the other side.

[0059] A permanent magnet is arranged at the inner side of the carrier 4 where the coil 82 is in contact with the carrier 4. When the coil 82 is energized, it cooperates with the permanent magnet in the carrier 4 to drive the carrier 4 to move.

[0060] refer to Figure 8 The pressing block 42 cooperates with the conveyor belt mechanism 65 on the second conveyor line 62. When the pressing block 42 contacts the conveyor belt mechanism 65, a static friction force is generated to drive the pressing block 42 to move synchronously with the second conveyor line 62.

[0061] refer to Fig. 9 The line changing device 5 includes a reciprocating linear module 51 , and an electromagnetic module 8 is carried on the linear module 51 . The electromagnetic module 8 moves with the linear module 51 between the first conveying line 61 , the second conveying line 62 , and the third conveying line 63 .

[0062] Furthermore, the linear module 51 translates to dock the guide rail 64 that moves with itself with the guide rails 64 located on the first conveyor line 61 , the second conveyor line 62 , and the third conveyor line 63 , respectively, so as to guide the carrier 4 to move to the line changing device 5 .

[0063] The electromagnetic module 8 located on the line-changing device 5 can change the direction of the current in the coil 82, so that the carrier 4 gradually stops and remains motionless when the carrier 4 moves toward the line-changing device 5. When the carrier 4 leaves the line-changing device 5, a thrust is generated to drive the carrier 4 to move.

[0064] In some embodiments, the linear module 51 may be a cylinder, or a combination of a motor and a lead screw.

[0065] Embodiment 3

[0066] In combination with the above-mentioned embodiment 2, the present application also discloses an automated production line for quickly combining the modularization of the automated production line to form a new production line. This embodiment is based on the fact that multiple conveying devices 6 in embodiment 2 can be connected in series with each other, and a work station is set outside the first conveyor line 61 and the third conveyor line 63 on the conveying device 6, so that the conveying device 6 becomes a processing station.

[0067] The workstations have multiple functions. Both sides of each conveying device 6 are provided with workstations with a single function, and the workstations have different functions and corresponding processing stations, and the processing functions are also different, so that the first processing station, the second processing station, and more are formed according to the functional division.

[0068] Producers can quickly adjust the automated production line by adjusting the order between processing stations with different functions, as well as adding or removing a processing station.

[0069] Specifically, the processing stations may include a curing station, a pad printing station, and a sterilization station. Each processing station is provided with a workstation with corresponding functions, and the workstation is arranged outside the first conveying line 61 and the third conveying line 63 on the conveying equipment 6.

[0070] For example, according to the production capacity requirements, three curing stations need to be set up, that is, corresponding curing stations need to be set up in the production line, and by increasing the span of the material transmission line 3, multiple stations can be added to meet the curing requirements.

[0071] Taking contact lens preparation as an example:

[0072] In the process of preparing contact lenses, if the production requirements of the manufacturer change from producing five-color contact lenses to producing four-color contact lenses, it can be achieved by removing a group of pad printing stations and reducing one transfer step;

[0073] If the manufacturer's production needs increase the number of five-color contact lenses to six-color contact lenses, six-color pad printing can be achieved by adding a set of pad printing stations.

[0074] When the producer's production needs change from preparing colored contact lenses to preparing colorless transparent contact lenses, all the pad printing stations can be withdrawn as a whole to achieve rapid switching of the line.

[0075] It should be noted that the above-mentioned preparation content of contact lenses is only used to explain the adjustment method of the automated production line disclosed in this embodiment, but the adjustment method of the automated production line in this embodiment is not limited to the preparation of contact lenses.
