Description

Technical Field

[0001] This application relates to the field of transportation technology, and more specifically, to a transportation system and a plant. Background Technology

[0002] After product manufacturing is completed, short-distance cross-product line deliveries are required. Currently, the delivery method involves first packaging the products using various packaging materials such as cartons and die-cut cards, then manually transferring or transporting the packaged products using forklifts or other conveyor vehicles. This not only increases packaging and labor costs but also causes product contamination during the packaging process, affecting delivery quality. Utility Model Content

[0003] In view of this, this application provides a transportation system and plant to solve the problem of potential product contamination during short-distance cross-product line transfers in the prior art.

[0004] One embodiment of this application provides a transport system for transferring materials. The transport system includes multiple clean units and transport devices. Each clean unit includes a clean device and a transport pipe. The multiple transport pipes are connected sequentially to form a transport channel. The transport channel has two inlets / outlets for material entry and exit. The clean devices and transport pipes are connected to ensure that the cleanliness level within the transport channel meets a preset standard. The transport device includes a first transport mechanism. The first transport mechanism is at least partially located within the transport channel. The first transport mechanism is used to transport materials between the two inlets / outlets.

[0005] Multiple cleanroom units are connected via transport pipes to form a transport channel, with material entry and exit at both ends. The cleanroom equipment ensures that the cleanliness level within the transport channel meets preset standards. A first transport mechanism installed within the transport channel enables automated material transfer; workers only need to load and unload materials at either end of the channel. This transport system is suitable for short-distance cross-product line material transfer or transport. When the transfer distance increases, the length of the transport channel can be extended by adding cleanroom units. This allows materials to be transferred in a cleanroom environment, effectively preventing contamination during cross-product line deliveries.

[0006] In some embodiments, the transport channel is configured to be above ground level. The space between the transport channel and the ground is used for user passage. The transport device also includes lifting mechanisms. There are two lifting mechanisms. The two lifting mechanisms are respectively located at the two entrances and exits of the transport channel to lift or lower materials.

[0007] Setting the transport channel above ground utilizes underutilized space above ground, effectively saving floor space. The space between the transport channel and the ground can be used for user passage. Lifting mechanisms are installed at the entrance and exit of the transport channel to raise or lower materials. Workers simply need to put materials into or retrieve them from the lifting mechanism.

[0008] In some embodiments, the lifting mechanism has a first exchange station and a second exchange station spaced apart along the lifting direction. The lifting mechanism includes a lifting platform and a drive mechanism. The lifting platform is used to exchange materials with a first transport mechanism at the first exchange station and to exchange materials with the outside at the second exchange station. The drive mechanism is used to drive the lifting platform to move up and down.

[0009] Setting up fixed first and second exchange stations for material transfer on the lifting mechanism helps to standardize the material transfer process.

[0010] In some embodiments, the transport device further includes a second transport mechanism. The lifting mechanism has a first exchange station and a second exchange station spaced apart along the lifting direction. The first transport mechanism engages with the lifting mechanism at the first exchange station to allow material to be transferred between the lifting mechanism and the first transport mechanism. The second transport mechanism engages with the lifting mechanism at the second exchange station to allow material to be transferred between the lifting mechanism and the second transport mechanism.

[0011] A second transport mechanism is further set up on the ground, which connects the first exchange station of the lifting mechanism with the first transport mechanism, and the second exchange station with the second transport mechanism. This enables efficient transfer of materials between different heights and makes the transfer of materials smoother, helping to ensure that materials can be transferred in an orderly manner between the ground and the transport pipeline.

[0012] In some embodiments, the transport system further includes a vehicle. The vehicle is used to carry materials.

[0013] There are inevitably gaps where the lifting mechanism connects with the first and second transport mechanisms. The vehicle helps to ensure that materials can be safely transferred between the first transport mechanism and the lifting mechanism, and between the lifting mechanism and the second transport mechanism.

[0014] In some embodiments, the number of lifting platforms is multiple. These multiple lifting platforms are spaced apart.

[0015] The addition of multiple lifting platforms to the mechanism can further improve the efficiency of material transfer.

[0016] In some embodiments, the drive mechanism includes a first lifting chain and a second lifting chain. The first lifting chain is connected to the front end of the lifting platform. The second lifting chain is connected to the rear end of the lifting platform. The first and second lifting chains move in the same direction to drive the lifting platform to rise or fall between the first and second exchange stations.

[0017] The front and rear ends of the lifting platform are connected to the first lifting chain and the second lifting chain, respectively, so that the lifting platform can carry materials to move along the lifting direction of the lifting mechanism.

[0018] In some embodiments, the drive mechanism further includes a first sprocket assembly and a second sprocket assembly. A first lifting chain is disposed on the first sprocket assembly. The first sprocket assembly rotates to drive the first lifting chain to rotate cyclically. A second lifting chain is disposed on the second sprocket assembly. The second sprocket assembly rotates to drive the second lifting chain to rotate cyclically.

[0019] The first lifting chain is driven to rotate cyclically by the first sprocket set, and the second lifting chain is driven to rotate cyclically by the second sprocket set. The first and second lifting chains move in the same direction. With regard to the lifting mechanism at one end of the transport channel, this lifting mechanism allows the lifting platform to move along a predetermined path instead of reciprocating between the first and second exchange stations, driven by the first and second lifting chains, thus completing the switching between the first and second exchange stations and achieving cyclic lifting.

[0020] In some embodiments, the lifting platform includes a chain support plate and a connector. The front end of the chain support plate is connected to a first lifting chain via the connector, and the rear end of the chain support plate is connected to a second lifting chain via the connector. The chain support plate includes a plurality of parallel and spaced-apart chain plate members. The plurality of chain plate members are hinged to each other.

[0021] Multiple chain plate components are hinged together to form a continuous bearing surface, and can be driven to move by the first lifting chain and the second lifting chain.

[0022] In some embodiments, the number of transport devices is two sets. The first transport mechanism of both sets of transport devices is located within the transport channel. The material transfer directions within the two sets of transport devices are opposite.

[0023] The first transport mechanism of the two sets of transport devices can realize bidirectional material transfer within a transport channel, and one set of transport devices can also serve as a carrier recovery line for the other set of transport devices.

[0024] In some embodiments, the number of transport devices is two sets. The number of transport channels is two. The first transport mechanism of one set of transport devices is located in one transport channel. The material transfer directions within the two sets of transport devices are opposite.

[0025] The first transport mechanism of each transport unit is independently set up in a transport channel, which can realize bidirectional material transfer and facilitate independent cleaning of each transport channel and its corresponding first transport mechanism.

[0026] One embodiment of this application provides a factory building. The factory building includes a building structure and a transportation system. Multiple cleanroom units are disposed within the building structure.

[0027] Multiple cleanroom units can be installed above the ground within the building structure, creating a space between the transport corridor and the ground for personnel and other equipment to pass through.

[0028] In some embodiments, the building structure includes walls. The walls serve to divide the building structure. Transport passages pass through the walls. Fire-resistant roller shutters are installed at the points where the transport passages pass through the walls to form fire-resistant partitions.

[0029] When the transport passage passes through the walls of the building structure, in order to ensure that the original fire protection facilities of the factory are not affected by the installation of the transport system, fireproof roller shutters are installed at the walls through which the transport passage passes, so as to prevent the spread of fire in the event of a fire.

[0043] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component present at the same time.

[0044] Embodiments of this application provide a transport system for transferring materials. The transport system includes multiple clean units and transport devices. Each clean unit includes a clean device and a transport pipe. Multiple transport pipes are connected sequentially to form a transport channel. The transport channel has two inlets / outlets for material entry and exit. The clean device and transport pipes are connected to ensure that the cleanliness level within the transport channel meets a preset standard. The transport device includes a first transport mechanism. The first transport mechanism is at least partially located within the transport channel. The first transport mechanism is used to transport materials between the two inlets / outlets.

[0045] Multiple cleanroom units are connected via transport pipes to form a transport channel, with material entry and exit at both ends. The cleanroom equipment ensures that the cleanliness level within the transport channel meets preset standards. A first transport mechanism installed within the transport channel enables automated material transfer; workers only need to load and unload materials at either end of the channel. This transport system is suitable for short-distance cross-product line material transfer or transport. When the transfer distance increases, the length of the transport channel can be extended by adding cleanroom units. This allows materials to be transferred in a cleanroom environment, effectively preventing contamination during cross-product line deliveries.

[0046] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0047] Please see Figure 1 and Figure 2 One embodiment of this application provides a transport system 100 for transferring material 3. The transport system 100 includes multiple clean units 1 and transport devices 2. Each clean unit 1 includes a clean device 11 and a transport pipe 12. Multiple transport pipes 12 are sequentially connected to form a transport channel 101. The transport channel 101 has two inlets / outlets for material 3 to enter and exit, including an outlet 1011 and an inlet 1012. The clean device 11 and the transport pipes 12 are connected to ensure that the cleanliness level within the transport channel 101 meets a preset standard. The transport device 2 includes a first transport mechanism 21. The first transport mechanism 21 is at least partially located within the transport channel 101. The first transport mechanism 21 is used to transport material 3 between the outlet 1011 and the inlet 1012. In some embodiments, the number of outlets 1011 and the number of inlets 1012 are multiple, so that loading and unloading can be completed at the location required by the user.

[0048] Multiple cleanroom units 1 have interconnected transport pipes 12 to form a transport channel 101. Materials 3 enter and exit at both ends of the transport channel 101. The cleanroom device 11 ensures that the cleanliness level within the transport channel 101 meets preset standards. A first transport mechanism 21 installed within the transport channel 101 enables automated transfer of materials 3; workers only need to load and unload materials at both ends of the transport channel 101. The transport system 100 of this application is suitable for short-distance cross-product line material transfer or transport. When the transfer distance increases, the length of the transport channel 101 can be extended by adding cleanroom units 1. In this way, materials 3 are transferred in a cleanroom environment, effectively preventing contamination of materials 3 during cross-product line deliveries.

[0049] Cleanroom unit 11 is a self-powered air purification device, including a built-in fan and a filter. The filter can be a high-efficiency particulate air filter (HEPA) or an ultra-low penetration air filter (ULPA). The cleanroom unit 1 (FanFilter Unit) works by drawing in indoor air through the fan, filtering it, and then delivering clean air in a laminar flow into the transport channel 101, thus creating a cleanroom. The cleanliness level of the transport channel 101 only needs to be Class 100. Understandably, the multiple transport pipes 12 should be sealed together. In some embodiments, the transport pipes 12 are made of rock wool board, and the cleanroom unit 11 is located on top of the transport pipes 12.

[0050] In some embodiments, the transport channel 101 is configured to be above ground level. The space between the transport channel 101 and the ground is used for user passage. The transport device 2 also includes two lifting mechanisms 22. The two lifting mechanisms 22 are respectively disposed at the outlet 1011 and the inlet 1012 of the transport channel 101 to lift or lower the material 3.

[0051] By setting the transport channel 101 above ground level, it utilizes the underutilized space above ground, effectively saving ground space. The space between the transport channel 101 and the ground can be used for user passage. Users include people or other transport devices. Lifting mechanisms 22 are then installed at the exit 1011 and entrance 1012 of the transport channel 101 to lift or lower the materials 3. Workers only need to place the materials 3 into or remove them from the lifting mechanism 22.

[0052] In some embodiments, the lifting mechanism 22 has a first exchange station 2201 and a second exchange station 2202 spaced apart along the lifting direction. The lifting mechanism 22 includes a lifting platform 221 and a drive mechanism 222. The lifting platform 221 is used to exchange materials 3 with the first transport mechanism 21 at the first exchange station 2201 and to exchange with the outside at the second exchange station 2202. The drive mechanism 222 is used to drive the lifting platform 221 to lift.

[0053] Setting up fixed first exchange station 2201 and second exchange station 2202 for transferring material 3 on the lifting mechanism 22 helps to standardize the material 3 transfer process. The first exchange station 2201 is farther from the ground than the second exchange station 2202.

[0054] In some embodiments, the transport device 2 further includes a second transport mechanism 23. The lifting mechanism 22 has a first exchange station 2201 and a second exchange station 2202 spaced apart along the lifting direction. The first transport mechanism 21 connects to the lifting mechanism 22 at the first exchange station 2201 to allow material 3 to be transferred between the lifting mechanism 22 and the first transport mechanism 21. The second transport mechanism 23 connects to the lifting mechanism 22 at the second exchange station 2202 to allow material 3 to be transferred between the lifting mechanism 22 and the second transport mechanism 23.

[0055] A second transport mechanism 23 is further set up on the ground. The first exchange station 2201 of the lifting mechanism 22 is connected to the first transport mechanism 21, and the second exchange station 2202 is connected to the second transport mechanism 23. This realizes the efficient transfer of material 3 between different heights and makes the transfer of material 3 smoother, which helps to ensure that material 3 can be transferred in an orderly manner between the ground and the transport pipeline 12.

[0056] In some embodiments, the first transport mechanism 21 is an electrostatic flat belt conveyor, which can effectively prevent static electricity or dust from contaminating the transport channel 101. The second transport mechanism 23 can be a conveyor belt.

[0057] In some embodiments, the transport system 100 further includes a vehicle 4. The vehicle 4 is used to carry the material 3.

[0058] Gaps inevitably exist at the points where the lifting mechanism 22 connects with the first transport mechanism 21 and the second transport mechanism 23. The carrier 4 helps ensure that the material 3 can be safely transferred between the first transport mechanism 21 and the lifting mechanism 22, and between the lifting mechanism 22 and the second transport mechanism 23. The carrier 4 may have two or more bearing cavities, so that one carrier 4 can carry more than one material 3, thereby improving the transfer efficiency of the material 3. In some embodiments, the carrier 4 may be a dual-cavity carrier.

[0059] In some embodiments, the number of lifting platforms 221 is multiple. The multiple lifting platforms 221 are arranged at intervals.

[0060] The lifting mechanism 22 is equipped with multiple lifting platforms 221, which can further improve the transfer efficiency of materials 3.

[0061] In some embodiments, the drive mechanism 222 includes a first lifting chain 2221 and a second lifting chain 2222. The first lifting chain 2221 is connected to the front end of the lifting platform 221. The second lifting chain 2222 is connected to the rear end of the lifting platform 221. The first lifting chain 2221 and the second lifting chain 2222 move in the same direction to drive the lifting platform 221 to rise or fall between the first exchange station 2201 and the second exchange station 2202.

[0062] The front and rear ends of the lifting platform 221 are connected to the first lifting chain 2221 and the second lifting chain 2222 respectively, so that the lifting platform 221 can carry the material 3 to move along the lifting direction of the lifting mechanism 22.

[0063] In some embodiments, the drive mechanism 222 further includes a first sprocket assembly 2223 and a second sprocket assembly 2224. A first lifting chain 2221 is disposed on the first sprocket assembly 2223. The first sprocket assembly 2223 rotates to drive the first lifting chain 2221 to rotate cyclically. A second lifting chain 2222 is disposed on the second sprocket assembly 2224. The second sprocket assembly 2224 rotates to drive the second lifting chain 2222 to rotate cyclically.

[0064] The first lifting chain 2221 is driven to rotate cyclically by the first sprocket set 2223, and the second lifting chain 2222 is driven to rotate cyclically by the second sprocket set 2224. The first lifting chain 2221 and the second lifting chain 2222 move in the same direction. With regard to the lifting mechanism 22 at one end of the transport channel 101, the lifting platform 221 does not need to move up and down between the first exchange station 2201 and the second exchange station 2202. Instead, it can move along a predetermined path under the drive of the first lifting chain 2221 and the second lifting chain 2222, thereby completing the switching between the first exchange station 2201 and the second exchange station 2202 and realizing cyclic lifting.

[0065] Please see Figure 3 and Figure 4The lifting mechanism 22 is symmetrical on both sides. The entire lifting mechanism 22 includes two first lifting chains 2221 and two second lifting chains 2222. Taking one side as an example, the outer lifting chain is the first lifting chain 2221, and the inner lifting chain is the second lifting chain 2222. The first sprocket group 2223 includes a first outer sprocket 2223a, a second outer sprocket 2223b, a third outer sprocket 2223c, a fourth outer sprocket 2223d, and a fifth outer sprocket 2223e. The first lifting chain 2221 is sequentially wound around the first outer sprocket 2223a, the second outer sprocket 2223b, the third outer sprocket 2223c, the fourth outer sprocket 2223d, and the fifth outer sprocket 2223e. The second sprocket assembly 2224 includes a first inner sprocket 2224a, a second inner sprocket 2224b, a third inner sprocket 2224c, and a fourth inner sprocket 2224d. A second lifting chain 2222 is sequentially wound around the first inner sprocket 2224a, the second inner sprocket 2224b, the third inner sprocket 2224c, and the fourth inner sprocket 2224d. The drive mechanism 222 further includes a drive motor 2225. The first outer sprocket 2223a and the first inner sprocket 2224a are coaxially rotatably connected and driven to rotate by the drive motor 2225. The first outer sprocket 2223a and the first inner sprocket 2224a rotate in the same direction. The fourth outer sprocket 2223d and the third inner sprocket 2224c are coaxially rotatably connected, and the fifth outer sprocket 2223e and the fourth inner sprocket 2224d are coaxially rotatably connected. The second outer sprocket 2223b guides the first lifting chain 2221, and the second inner sprocket 2224b guides the second lifting chain 2222. The second outer sprocket 2223b and the second inner sprocket 2224b are at the same height. The second outer sprocket 2223b is closer to the second transport mechanism 23 than the second inner sprocket 2224b, and the second inner sprocket 2224b is closer to the first transport mechanism 21 than the second outer sprocket 2223b. The second outer sprocket 2223b rotates in the opposite direction to the first outer sprocket 2223a, and the second inner sprocket 2224b rotates in the opposite direction to the first inner sprocket 2224a. The third outer sprocket 2223c, the fourth outer sprocket 2223d, and the fifth outer sprocket 2223e rotate in the same direction as the first outer sprocket 2223a, and the third inner sprocket 2224c, the fourth inner sprocket 2224d, and the first inner sprocket 2224a rotate in the same direction. The instruction manual is required to clearly demonstrate the structure of the drive mechanism 222. Figure 3 and Figure 4 The lifting mechanism 22 shown does not include the frame and baffle structure.

[0066] Taking the sequential transfer of material 3 from the first transport mechanism 21 to the lifting mechanism 22 and the second transport mechanism 23 as an example, the lifting mechanism 22 is used to lower material 3. Driven by the first transport mechanism 21, a portion of the carrier 4 is located at the front end of the lifting platform 221 at the first exchange station 2201. As the lifting mechanism 22 operates, the first lifting chain 2221 and the second lifting chain 2222 drive the lifting platform 221 forward along the movement path, simultaneously moving the carrier 4 along with it. When the entire lifting platform 221 is at the height of the first exchange station 2201, the entire carrier 4 is also located on the lifting platform 221. Then, the lifting platform 221 is lowered until it reaches the second exchange station 2202. The front end of the lifting platform 221 leaves the second exchange station 2202, and a portion of the carrier 4 is placed on the second transport mechanism 23. When the rear end of the lifting platform 221 also leaves the second exchange station 2202, the entire carrier 4 is located on the second transport mechanism 23.

[0067] Please continue Figure 3 and Figure 4 Taking the illustrated embodiment as an example, the front end of the lifting platform 221 refers to the end of the lifting platform 221 that is close to the second transport mechanism 23 when it carries material 3, and the rear end refers to the end that is close to the first transport mechanism 21. When the lifting mechanism 22 is used to lift material 3, the movement direction of the first lifting chain 2221 and the second lifting chain 2222 close to the second transport mechanism 23 is from the second exchange station 2202 to the first exchange station 2201, that is, from bottom to top. When the lifting platform 221 is lifted to the first exchange station 2201, the lifting platform 221 will move downward with the first lifting chain 2221 and the second lifting chain 2222. In this way, the movement path of the lifting platform 221 is cyclical, and it is not necessary to lift one lifting platform 221 and then lower it before the next lifting. Multiple lifting platforms 221 can realize the cyclical transfer of material 3.

[0068] In some embodiments, the lifting platform 221 includes a chain support plate 2211 and a connector 2212. The front end of the chain support plate 2211 is connected to a first lifting chain 2221 via the connector 2212, and the rear end of the chain support plate 2211 is connected to a second lifting chain 2222 via the connector 2212. The chain support plate 2211 includes a plurality of parallel and spaced chain plate members. The plurality of chain plate members are hinged to each other.

[0069] Multiple chain plate components are hinged together to form a continuous bearing surface, and can be driven to move by the first lifting chain 2221 and the second lifting chain 2222.

[0070] The lifting mechanism 22 in the various embodiments of this application is made of stainless steel, which can greatly reduce the probability of dust generation from wear during the use of the lifting mechanism 22.

[0071] In some embodiments, the number of transport devices 2 is two sets. The first transport mechanism 21 of both sets of transport devices 2 is located within the transport channel 101. The transfer direction of the material 3 within the two sets of transport devices 2 is opposite.

[0072] The first transport mechanism 21 of the two sets of transport devices 2 can realize bidirectional material 3 transfer within a transport channel 101. One set of transport devices 2 can also serve as a carrier 4 recovery line for the other set of transport devices 2.

[0073] In some embodiments, there are two sets of transport devices 2. There are two transport channels 101. The first transport mechanism 21 of one set of transport devices 2 is located in one transport channel 101. The materials 3 are transferred in opposite directions in the two sets of transport devices 2.

[0074] The first transport mechanism 21 of each transport device 2 is independently set in a transport channel 101, which can realize the bidirectional transfer of materials 3, and also facilitates the independent cleaning of each transport channel 101 and the corresponding first transport mechanism 21.

[0075] Please see Figure 5 and Figure 6 One embodiment of this application provides a factory building 200. The factory building 200 includes a building structure 5 and a transportation system 100. Multiple cleanroom units 1 are disposed within the building structure 5.

[0076] Multiple cleanroom units 1 can be installed above the ground inside the building structure 5, so that a space for users to pass through is formed between the transport channel 101 and the ground.

[0077] In some embodiments, the building structure 5 is provided with walls 501. Walls 501 are used to divide the building structure 5. A transport passage 101 passes through the wall 501. Fireproof roller shutters 6 are provided at the points through which the transport passage 101 passes in the wall 501 to form fire-resistant partitions.

[0078] After the transport channel 101 passes through the wall 501 of the building structure 5, in order to ensure that the original fire protection facilities of the factory 200 are not affected by the installation of the transport system 100, a fireproof roller shutter 6 is installed at the wall 501 through which the transport channel 101 passes, so as to prevent the spread of fire in the event of a fire.

[0079] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
