Description

Technical Field

[0001] This invention relates to the field of building material preparation technology, specifically to an automated circular production process for prefabricated components. Background Technology

[0002] Currently, precast concrete components (also known as PC precast components) refer to assembled concrete components that are prefabricated before installation on the construction site. PC component production lines are generally arranged in a horizontal, circulating manner, with each station performing a specific task. The advantage is that the production flow is very clear. Generally, a production line includes a demolding station, a cleaning station, a painting station, a rebar rack placement station, a concrete pouring station, and a vibration station. When the factory needs to improve efficiency, after the production line reaches its efficiency limit, a new production line will be introduced to increase production efficiency. However, two horizontal, circulating production lines occupy too much space, and because the two production lines are independent, it is difficult to coordinate them. For example, two independent conveyor chain structures are needed to achieve circulation, which can easily lead to increased costs. Based on this, engineers typically connect two production lines end-to-end in a vertical loop. The molds circulate sequentially between the two sets of workstations via a circular conveyor chain, reducing floor space, lowering costs, and improving the interoperability of the two production lines. However, with this method, a malfunction at one workstation can cause the entire production line to break down, affecting the entire processing cycle and reducing processing efficiency. Summary of the Invention

[0003] The purpose of this invention is to design an automated circular production process for precast components to solve the problems mentioned in the background art. To achieve the above objective, this invention provides the following production process: It includes two working groups, which are sequentially arranged with a demolding station, a cleaning station, a spraying station, a rebar frame placement station, a concrete pouring station, and a vibration station. The first and last stations of the two working groups are connected, and each station is arranged in a vertical ring. The vibrated mold is then sequentially sent to a pre-curing chamber, a high-temperature steam curing chamber, and a three-stage cooling chamber. The cooled mold is then sent to the demolding station. The mold table circulates sequentially from the workstations of the two work groups under the action of the circular conveyor chain. The circular conveyor chain, cleaning station, painting station, and rebar rack placement station are all equipped with normal working speed and emergency working speed. The emergency working speed is twice the normal working speed. The work group to which the workstation requiring maintenance is located is designated as the maintenance group, and the workstation requiring maintenance is designated as the maintenance station. When the cleaning station, painting station, or rebar rack placement station requires maintenance, the emergency process is activated. That is, the circular conveyor chain will cycle between the normal working speed and the emergency working speed, and the workstations before the maintenance station in the maintenance group will be suspended, while the remaining workstations will start normally.

[0004] Furthermore, the specific steps of the emergency process are as follows: S1. The circular conveyor chain and the workstations in the non-maintenance group maintain the normal working speed, and the workstations in the non-maintenance group that are before the workstations corresponding to the maintenance workstations are temporarily stopped. S2. Once all the molds after the maintenance station in the maintenance group have entered the pre-curing chamber, the circular conveyor chain will switch to emergency working speed. At the same time, the stations in the non-maintenance group before the maintenance station will start at emergency working speed, while the stations after the maintenance station will stop starting. The empty mold chamber will also be connected to the demolding station in the non-maintenance group and will work in conjunction with the original demolding station to stagger the delivery of the demolded molds to the mold table. S3. When the mold table in the non-maintenance group corresponding to the maintenance station circulates to the maintenance station in the maintenance group, the circular conveyor chain will switch to normal operating speed. At the same time, all stations in the non-maintenance group and the stations after the maintenance station in the maintenance group will operate at normal speed. In this cycle, the start-up of each station in the non-maintenance group and the maintenance group is determined by the gravity-vision linkage system. The gravity-vision linkage system determines the mold status on the mold table in the cycle and feeds it back to the corresponding station. The station will only start when the mold status corresponds to the station. When the mold table in the maintenance station in the maintenance group circulates to the station in the non-maintenance group corresponding to the maintenance station, it will enter the S1 process, at which point the cycle between S1 and S3 is completed.

[0005] Furthermore, the cleaning station, spraying station, rebar rack placement station, concrete pouring station, and vibration station in each group are arranged vertically, with two stations at the same height. The two demolding stations are located above and below the other stations, respectively, and are both located between the two vertically arranged groups of stations. In each level, there are two emergency stations with the same function as the two stations at the same level. The emergency stations with the same function are located on a circular track and can be fixed on the circular track. When a station at the same level needs to be inspected or maintained, it is only necessary to swap the station at the same level with the emergency station.

[0006] Furthermore, the emergency workstation is also equipped with a commissioning workstation on the same floor for debugging, inspection and maintenance, and the commissioning workstation is located between two circular tracks.

[0007] Furthermore, the circular track is L-shaped, and the two circular tracks at the same level are U-shaped, with the two workstations at the same level located on parallel circular tracks within the U-shape.

[0008] Furthermore, the pouring pipes in the two concrete pouring stations are connected to a concrete mixing device through a pouring pipe network, and a feed storage tank is provided at the end of the pouring pipe network. The discharge pipe of the concrete mixing device is connected to the feed storage tank. When the concrete mixing device needs to be inspected and maintained, the feed storage tank can temporarily supply concrete to the production.

[0009] Furthermore, the gravity-vision linkage system classifies the state of the mold platform into six states: moldless state, waiting to be cleaned, waiting to be sprayed with paint, waiting to be placed, waiting to be poured, and waiting to be vibrated. After the determination is completed, the corresponding color light one to color light six will light up on the mold platform. The light colors of color lights one to color light six are different. Each of the six workstations in the group is equipped with a recognition system to identify the corresponding color light to determine whether the workstation should be activated. Specifically, when color light one is identified at the demolding workstation, the demolding workstation is activated; when color light two is identified at the cleaning workstation, the cleaning workstation is activated; when color light three is identified at the spraying workstation, the spraying workstation is activated; when color light four is identified at the rebar placement workstation, the rebar placement workstation is activated; when color light five is identified at the concrete pouring workstation, the concrete pouring workstation is activated; and when color light six is ​​identified at the vibration workstation, the vibration workstation is activated.

[0010] Furthermore, the gravity-vision linkage system includes a gravity analysis system located at the bottom of the mold platform and a vision analysis system located at the top of the mold platform. The gravity analysis system first analyzes the weight placed on the mold platform and classifies it into four weight levels from lightest to heaviest: Level 1, Level 2, Level 3, and Level 4. Level 1 weight determines the state of the mold platform as moldless; Level 2 weight determines the state as awaiting cleaning, awaiting painting, or awaiting placement; Level 3 weight determines the state as awaiting casting; and Level 4 weight... The state of the mold platform is determined to be in the state of needing vibration. When the gravity analysis system classifies the state of the mold platform to the secondary weight, the vision analysis system is activated. The system captures an image through a camera and compares it with a standard image of the cleaned mold through a comparison system. When the similarity between the two images is less than 96%, the state of the mold platform is determined to be in the state of needing cleaning. When the similarity is greater than 96%, the brightness of the two images is compared. If the brightness is higher than that of the standard image, the state of the mold platform is determined to be in the state of needing to be poured. If the brightness is lower than that of the standard image, the state of the mold platform is determined to be in the state of needing to be sprayed with oil.

[0011] Furthermore, the identification system is also equipped with an alarm system. When the identification system of a workstation detects a color that does not match the color of the light at that workstation, it will issue a warning to the staff, thereby determining that the previous workstation of that workstation has malfunctioned during operation.

[0012] An automated circular production equipment for precast components includes a U-shaped fixed frame with several layers and a circular conveyor chain located inside the U-shaped fixed frame. The U-shaped fixed frame includes two parallel workstation supports and a corridor connecting the two workstation supports. A cleaning module, a spraying module, a rebar placement module, a concrete pouring module, and a vibration module are sequentially arranged in each layer of the workstation supports. The arrangement order of the modules in the two workstation supports is reversed. Demolding modules are located in the top and bottom layers of the corridor, respectively. All modules are distributed in a circular pattern. The circular conveyor chain is equipped with mold platforms that are aligned with each module. One of the mold platforms is aligned with each module sequentially under the action of the circular conveyor chain. The mold platform remains horizontal during the conveying process of the circular conveyor chain. Each module is equipped with a transfer mechanism for moving the mold to the mold platform or the corresponding module.

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] Example: An automated circular production process for prefabricated components, comprising the following steps; S01. The inside of the mold is cleaned at cleaning station 2, and then the mold table moves the cleaned mold to spray painting station 3. S02. Spray oil on the inside of the mold at the spraying station 3, and then the mold table moves the sprayed mold to the steel bar frame placement station 4. S03. At the rebar frame placement station 4, the already tied rebar cage is placed inside the mold. Then the mold table moves the mold after placing the rebar cage to the concrete pouring station 5. S04. At the concrete pouring station 5, the mixed concrete is poured into the mold, and then the mold platform moves the poured mold to the vibration station 6. S05. Vibrate the concrete inside the mold at the vibration station 6, and then the mold table moves the vibrated mold to the pre-curing chamber for initial setting. S06. The mold containing the partially set concrete is sent to a high-temperature steam curing chamber for curing. S07. The mold containing the cured concrete is sent to the three-stage cooling chamber for gradual cooling. S08. The mold containing the gradually cooled concrete is sent to the demolding station 1 for demolding. After demolding, the mold will be moved to the cleaning station 2 under the action of the mold table. The demolding station 1, cleaning station 2, spraying station 3, rebar frame placement station 4, concrete pouring station 5, and vibration station 6 in S01 to S08 are arranged in two sets in sequence. The first and last stations in the two sets are connected to form a vertical ring shape. The mold table circulates sequentially from the two sets of stations under the action of the ring conveyor chain 7. Therefore, in this invention, two production lines are arranged vertically and transported by a single ring conveyor chain 7, thereby reducing the floor space and lowering the cost.

[0020] The circular conveyor chain 7, cleaning station 2, oil spraying station 3, and rebar rack placement station 4 are all equipped with normal operating speeds and emergency operating speeds. The emergency operating speed is twice the normal operating speed. When cleaning station 2, oil spraying station 3, or rebar rack placement station 4 in one of the groups requires maintenance, the emergency process can be activated; that is, the circular conveyor chain 7 will cycle between the normal operating speed and the emergency operating speed. The stations before the maintenance station in the maintenance group will be suspended, while the remaining stations will operate normally. Specifically: S1, the circular conveyor chain 7, and the workstations in the non-maintenance group maintain the normal working speed, and the workstations in the non-maintenance group before the workstations corresponding to the maintenance workstations are temporarily stopped until all the molds after the maintenance workstations in the maintenance group enter the pre-curing chamber. S2. When all the molds after the maintenance station in the maintenance group enter the pre-curing chamber, the circular conveyor chain 7 will switch to emergency working speed. At the same time, the stations in the non-maintenance group before the maintenance station will start at emergency working speed, and the stations after the maintenance station will stop starting. The empty mold chamber will also be connected to the demolding station 1 in the non-maintenance group and will cooperate with the original demolding station 1 to stagger the delivery of the demolded molds to the mold table. S3. When the mold table in the non-maintenance group corresponding to the maintenance station circulates to the maintenance station in the maintenance group, the circular conveyor chain 7 will switch to normal operating speed. At the same time, all stations in the non-maintenance group and the stations after the maintenance station in the maintenance group will adopt normal operating speed. In this cycle, the start-up of each station in the non-maintenance group and the maintenance group is determined by the gravity-vision linkage system. The gravity-vision linkage system determines the mold status on the mold table in the cycle and feeds it back to the corresponding station. The station will only start when the mold status corresponds to the station. When the mold table in the maintenance station in the maintenance group circulates to the station in the non-maintenance group corresponding to the maintenance station, it will enter the S9 process, at which point the cycle between S9 and S11 is completed.

[0021] In each group, cleaning station 2, spray painting station 3, rebar frame placement station 4, concrete pouring station 5, and vibration station 6 are arranged vertically, with two stations on the same level. Two demolding stations 1 are located above and below the other stations, respectively, and are situated between two vertically arranged groups of stations. When any station other than demolding station 1 requires maintenance, emergency process two can be activated, specifically: S4. Each level has two emergency workstations with the same function as the two workstations on the same level. The emergency workstations with the same function are located on a circular track and can be fixed on the circular track. When the workstations on the same level need to be inspected or maintained, the workstations on the same level and the emergency workstations can be swapped.

[0022] In S4, the original emergency workstation is also equipped with a commissioning workstation on the same level for debugging, inspection and maintenance. The commissioning workstation is located between two circular tracks.

[0023] The circular track is L-shaped, and the two circular tracks at the same level are U-shaped. The two workstations at the same level are located on parallel circular tracks in the U-shape.

[0024] It also includes Emergency Process 3; Emergency Process 3 is applied to concrete pouring station 5, specifically as follows: S5. The pouring pipes in the two concrete pouring stations 5 are connected to a concrete mixing device through a pouring pipe network, and a feed storage tank is provided at the end of the pouring pipe network. The discharge pipe of the concrete mixing device is connected to the feed storage tank. When the concrete mixing device needs to be repaired or maintained, the feed storage tank can temporarily supply concrete to the production.

[0025] In one embodiment, the gravity-vision linkage system determines the state of the mold table into six states: moldless state, waiting to be cleaned, waiting to be sprayed with oil, waiting to be placed, waiting to be poured, and waiting to be vibrated. After the determination is completed, the corresponding color light one to color light six will light up on the mold table. The light colors of color light one to color light six are different. Each of the six workstations in the group is equipped with a recognition system that identifies the corresponding color light to determine whether the workstation should be activated. Specifically, demolding workstation 1 corresponds to color light one, cleaning workstation 2 corresponds to color light two, spraying workstation 3 corresponds to color light three, rebar frame placement workstation 4 corresponds to color light four, concrete pouring workstation 5 corresponds to color light five, and vibration workstation 6 corresponds to color light six. The gravity-vision linkage system includes a gravity analysis system located at the bottom of the mold platform and a vision analysis system located at the top of the mold platform. The gravity analysis system first analyzes the weight placed on the mold platform and classifies it into four weight levels from lightest to heaviest: Level 1, Level 2, Level 3, and Level 4. Level 1 weight determines the state of the mold platform as unmolded; Level 2 weight determines the state as awaiting cleaning, painting, or placement; Level 3 weight determines the state as awaiting pouring; and Level 4 weight determines the state as awaiting vibration. When gravity... When the analysis system classifies the state of the mold table to the second-level weight, the vision analysis system is activated. It captures images through a camera and compares them with a standard image of the cleaned mold to check for differences in brightness. When the similarity is less than 96%, the mold table is classified as awaiting cleaning. When the similarity is greater than 96%, the brightness of the two images is compared. If the brightness is higher than the standard image, the mold table is classified as awaiting pouring; if the brightness is lower than the standard image, the mold table is classified as awaiting painting. Ultimately, this ensures the smoothness of the entire process cycle.

[0026] In one embodiment, the identification system is also equipped with an alarm system. When the identification system of a workstation identifies a color light that does not match the color light of that workstation, it will issue a warning to the worker, thereby determining that the previous workstation of that workstation has malfunctioned during operation.

[0027] The present invention also includes an automated circular production equipment for precast components, used for implementing the aforementioned production process. It includes a U-shaped fixed frame with several layers and a circular conveyor chain 7 located inside the U-shaped fixed frame. The U-shaped fixed frame includes two parallel workstation supports and a corridor connecting the two workstation supports. A cleaning module, a spraying module, a rebar placement module, a concrete pouring module, and a vibration module are sequentially arranged in each layer of the workstation supports. The arrangement order of the modules in the two workstation supports is reversed. Demolding modules are located in the top and bottom layers of the corridor, respectively. All modules are arranged in a circular pattern. The circular conveyor chain 7 is equipped with mold platforms aligned with each module. One mold platform aligns sequentially with each module under the action of the circular conveyor chain 7. The mold platform remains horizontal throughout the conveying process of the circular conveyor chain 7. Each module is equipped with a transfer mechanism for moving the mold to the mold platform or the corresponding module, thereby ensuring the cyclical operation of the above process.
