Abstract
Description
Technical Field
[0001] This invention relates to the field of building component molding technology, and in particular to a fully automated circulating processing line for ring molds. Background Technology
[0002] In the production of ring-shaped precast concrete components (such as short pipe piles and ring bricks), the disassembly, cleaning, reassembly, and re-pouring of molds are key factors restricting production efficiency. Traditional production methods often use linear assembly lines or fixed workstations, resulting in long mold turnover paths, waiting times between processes, low automation, high equipment vacancy rates, slow production cycles, large floor space requirements, and difficulty in achieving continuous assembly line operations. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a fully automated circulating processing line for ring molds, including a ring conveying mechanism and multiple automated functional stations arranged sequentially along the conveying direction. The multiple automated functional stations include:
[0004] The mold receiving station is used to receive the cast-in-place product that has been poured and has completed initial setting from the upstream concrete forming process.
[0005] The mold disassembly station is used to disassemble products with molds. The disassembly process includes removing external fasteners, releasing internal pressure in the mold, and separating the inner mold assembly from the outer mold assembly.
[0006] The component removal station is used to remove the already formed concrete components.
[0007] The mold reassembly station is used to reassemble the disassembled inner mold components and outer mold components into a complete mold.
[0008] The concrete pouring station is used to pour freshly mixed concrete into the reconstituted mold.
[0009] The mold sealing station is used to seal the injection port of the mold.
[0010] The mold delivery station is used to send out the molds that have been filled with concrete and return them to the upstream concrete forming process.
[0011] The circular conveyor operates in a cyclical manner, allowing the mold to flow sequentially through each workstation to complete the entire mold processing cycle from finished product demolding to new material injection. The circular conveyor adopts a stepping operation mode: as the mold flows with the circular conveyor to each automated functional workstation, the circular conveyor stops at each workstation to ensure that each workstation has sufficient time to complete the corresponding operation.
[0012] Furthermore, the mold includes an outer mold, an inner mold, a clamp, an air bladder, a circular lower sealing plate, and an annular upper sealing plate. The outer mold, inner mold, clamp, circular lower sealing plate, and annular upper sealing plate are at least partially made of ferromagnetic metal.
[0013] The outer mold adopts a split, detachable structure. The outer mold is composed of multiple circumferentially segmented pieces assembled to form an annular cavity. The outer side of the outer mold is secured by clamps. Several wedge-shaped recessed portions are provided on the inner wall of the outer mold.
[0014] The inner mold is nested within the inner cavity of the outer mold. The inner mold adopts a split, detachable structure. Multiple inner mold blocks are assembled circumferentially to form an annular cavity. The outer wall of the inner mold has a wedge-shaped protrusion that matches the wedge-shaped inward contraction. The gap between the outer mold and the inner mold forms a pre-reserved concrete cavity. A circular lower sealing plate seals the lower opening of the pre-reserved concrete cavity. An annular upper sealing plate seals the upper opening of the pre-reserved concrete cavity.
[0015] The airbag is a flexible bladder with an air valve. The airbag is fixedly connected to a circular lower sealing plate. In its flexible, stowed state, the airbag folds and retracts into the inner cavity of the inner mold. In its inflated state, the airbag has a composite shape with two parts. The portion of the airbag located within the inner cavity of the inner mold is cylindrical. This cylindrical portion expands radially, compressing the inner mold, with the outward and inward wedge-shaped sections abutting against each other, thereby locking the relative radial position of the inner and outer molds. The portion of the airbag extending beyond the inner mold expands to form a bulge shape. This bulge abuts against the annular upper sealing plate.
[0016] Furthermore, each automated workstation is equipped with different automatic actuators. These automatic actuators include drive components and pneumatic components.
[0017] The driving elements include robotic arms and electromagnetic devices. The component removal station is equipped with an electromagnetic device. The robotic arms include a type A robotic arm for overall movement, a type B robotic arm for inflation / deflation and movement of the annular upper sealing plate, a type C robotic arm for position control, a type D robotic arm for moving the clamp, a type E robotic arm for disassembling the inner and outer molds, and a type F robotic arm for grouting. The mold receiving station relies on type A robotic arms to move and transfer the molded product. The mold disassembly station relies on type B robotic arms to deflate the airbags and simultaneously use electromagnetic adsorption to pull away the annular upper sealing plate. Type C robotic arms press down on the inner and outer mold parts from the center. Type D robotic arms grasp the clamp and move it upwards, separating the clamp from the inner and outer molds. Multiple type E robotic arms use electromagnetic adsorption to sequentially remove the inner and outer mold components, completing mold disassembly. The electromagnetic device at the component removal station adsorbs and fixes the circular lower sealing plate, and then type A robotic arms complete the removal of the finished concrete component. The mold reassembly station uses multiple type E robotic arms to sequentially merge the inner and outer mold components using electromagnetic adsorption. The D-type robotic arm is then used to attach the remaining clamps to the outside of the inner and outer molds, completing the mold reassembly. At the concrete pouring station, the F-type robotic arm uses visual recognition to identify the pre-reserved concrete cavity and performs the concrete pouring operation. At the mold closing station, the B-type robotic arm uses an electromagnetic gripper to restore the annular upper sealing plate, followed by an inflation and sealing operation. At the mold delivery station, the A-type robotic arm completes the mold movement and transfer operation.
[0018] The pneumatic components include an automatic pneumatic interface a and an automatic pneumatic interface b. The mold disassembly station is equipped with an automatic pneumatic interface a that can connect to the air valve of the air bladder to perform an exhaust operation, causing the air bladder to contract and thus releasing its radial expansion lock between the outer and inner molds. The mold closing station is equipped with an automatic pneumatic interface b, which is used to inject gas into the air bladder, inflating it to a predetermined pressure to close the mold injection port and achieve radial locking of the inner and outer molds.
[0019] Furthermore, the dwell time of the circular conveyor at each workstation is controlled between 10 seconds and 600 seconds.
[0020] Furthermore, the annular conveying mechanism may employ an annular conveyor belt, a chain conveyor, an annular roller conveyor, or an intermittently driven rotary table.
[0021] Furthermore, the annular conveying mechanism is arranged at at least one end of the concrete centrifugal molding production line and is connected to the concrete centrifugal molding production line via a transfer robotic arm to receive molded products and deliver the poured molds.
[0022] Furthermore, there are two concrete centrifugal molding production lines, arranged in parallel and rotating in opposite directions. Correspondingly, there are two fully automated circular processing production lines for the annular mold, each connected to one of the centrifugal molding production lines and operating independently.
[0023] This invention also discloses a concrete component production process based on the above-mentioned fully automated circulating processing line using an annular mold, comprising the following steps:
[0024] S1) Mold receiving: The molded product that has been initially set in the upstream concrete forming process is placed at the mold receiving station of the ring conveyor mechanism by a transfer robotic arm.
[0025] S2) Mold disassembly: The annular conveyor mechanism sequentially sends the molds to the mold disassembly station, automatically removes the external clamps, releases the internal airbag pressure, and separates the outer mold.
[0026] S3) Component removal: The mold is sent to the component removal station, and the formed concrete component is automatically removed from the inner mold.
[0027] S4) Mold Reassembly: The separated inner and outer mold components are sent to the mold reassembly station, where the inner and outer molds are automatically reassembled above the bottom sealing plate, the airbag is placed in the middle, and the clamp is installed.
[0028] S5) Concrete pouring: The reconstructed mold is sent to the concrete pouring station, and freshly mixed concrete is automatically poured into the mold.
[0029] S6) Mold sealing: The mold is sent to the mold sealing station, and the airbag is automatically inflated to seal the mold injection port.
[0030] S7) Mold delivery: The mold that has been poured is delivered to the mold delivery station, and then transferred back to the upstream concrete forming process by a transfer robotic arm.
[0031] The technical effects of this invention are beyond doubt:
[0032] 1. High-efficiency continuous circulation: The circular closed-loop design eliminates the back-and-forth running of the mold and the waiting time between processes, realizing zero-interval connection of the mold processing flow and extremely high turnover efficiency.
[0033] 2. Fully automated flexible production: Each workstation is highly automated, and through program control, it can adapt to the rapid switching of different specifications of molds and products, resulting in good production flexibility and stable product quality.
[0034] 3. Compact spatial layout: The ring structure itself has the advantage of intensive space utilization and can be easily combined with the linear layout of upstream molding equipment, which greatly saves the workshop floor space.
[0035] 4. Strong system scalability: As an independent mold processing module, this circular production line can be modularly connected with single or multiple centrifugal lines or other types of molding equipment (such as vibration tables). The system configuration is flexible and easy to expand production capacity. Attached Figure Description

[0045] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0046] Example 1:
[0047] See Figure 1 and 2 This embodiment provides a fully automated circulating processing line for ring molds, including a ring conveyor mechanism and multiple automated functional stations arranged sequentially along the conveying direction. The multiple automated functional stations include:
[0048] The mold receiving station is used to receive the cast-in-place product that has been poured and has completed initial setting from the upstream concrete forming process.
[0049] The mold disassembly station is used to disassemble products with molds. The disassembly process includes removing external fasteners, releasing internal pressure in the mold, and separating the inner mold assembly from the outer mold assembly.
[0050] The component removal station is used to remove the already formed concrete components.
[0051] The mold reassembly station is used to reassemble the disassembled inner mold components and outer mold components into a complete mold.
[0052] The concrete pouring station is used to pour freshly mixed concrete into the reconstituted mold.
[0053] The mold sealing station is used to seal the injection port of the mold.
[0054] The mold delivery station is used to send out the molds that have been filled with concrete and return them to the upstream concrete forming process.
[0055] The circular conveyor operates in a cyclical manner, allowing the mold to flow sequentially through each workstation to complete the entire mold processing cycle from finished product demolding to new material injection. The circular conveyor adopts a stepping operation mode: as the mold flows with the circular conveyor to each automated functional workstation, the circular conveyor stops at each workstation to ensure that each workstation has sufficient time to complete the corresponding operation.
[0056] This embodiment integrates the entire mold processing process into a closed-loop system. Through the coordinated operation of the automatic actuators at each workstation, the mold can be used continuously and rapidly, thereby significantly improving production efficiency, reducing manual intervention, and saving production space.
[0057] Example 2:
[0058] See Figures 3-6 The main content of this embodiment is the same as that of Embodiment 1, wherein the mold includes an outer mold 1, an inner mold 2, a clamp 3, an air bladder 4, a circular lower sealing plate 7, and an annular upper sealing plate 8. The outer mold 1, inner mold 2, clamp 3, circular lower sealing plate 7, and annular upper sealing plate 8 are at least partially made of ferromagnetic metal.
[0059] The outer mold 1 adopts a split and detachable structure. The outer mold 1 is composed of multiple outer mold blocks assembled along the circumference to form an annular cavity. The outer side of the outer mold 1 is fixed by a clamp 3. The inner wall of the outer mold 1 is provided with several wedge-shaped inward recesses 1011.
[0060] The inner mold 2 is nested within the inner cavity of the outer mold 1. The inner mold 2 adopts a split, detachable structure. Multiple inner mold blocks are assembled circumferentially to form an annular cavity. The outer wall of the inner mold 2 has a wedge-shaped protrusion 2011 that matches the wedge-shaped inward contraction 1011. The gap between the outer mold 1 and the inner mold 2 forms a concrete pre-reserved cavity 6. The circular lower sealing plate 7 seals the lower opening of the concrete pre-reserved cavity 6. The annular upper sealing plate 8 seals the upper opening of the concrete pre-reserved cavity 6.
[0061] The airbag 4 is a flexible bladder with an air valve. The airbag 4 is fixedly connected to the circular lower sealing plate 7. In its flexible, stowed state, the airbag 4 is folded and retracted into the inner cavity of the inner mold 2. In its inflated state, the airbag 4 has a composite shape with two parts. The portion of the airbag 4 located within the inner cavity of the inner mold 2 is cylindrical. The cylindrical portion expands radially, compressing the inner mold 2, with the wedge-shaped outward protrusion 2011 and the wedge-shaped inward retraction 1011 abutting against each other, thereby locking the relative radial position of the inner and outer molds. The portion of the airbag 4 extending beyond the inner mold 2 expands to form a bulge shape. The bulge-shaped portion abuts against the annular upper sealing plate 8.
[0062] Each automated workstation is equipped with different automatic actuators. These automatic actuators include drive components and pneumatic components.
[0063] The driving elements include robotic arms and electromagnetic devices. The component removal station is equipped with an electromagnetic device. The robotic arms include a type A robotic arm for overall movement, a type B robotic arm for inflation / deflation and movement of the annular upper sealing plate 8, a type C robotic arm for position control, a type D robotic arm for moving the clamp 3, a type E robotic arm for disassembling the inner and outer molds, and a type F robotic arm for grouting. The mold receiving station relies on type A robotic arms to complete the movement and transfer of the molded product. The mold disassembly station relies on type B robotic arms to deflate the airbag 4 and simultaneously use electromagnetic adsorption to pull away the annular upper sealing plate 8. Type C robotic arms press down on the inner and outer mold parts from the center. Type D robotic arms grab the clamp 3 and move it upwards, separating the clamp 3 from the inner and outer molds. Multiple type E robotic arms use electromagnetic adsorption to sequentially remove the inner and outer mold components, completing the mold disassembly. The electromagnetic device at the component removal station adsorbs and fixes the circular lower sealing plate 7, and then type A robotic arms complete the removal operation of the finished concrete component. The mold reassembly station uses multiple type E robotic arms to sequentially merge the inner and outer mold components using electromagnetic adsorption. Then, a type D robotic arm places the remaining clamps (3) onto the outside of the inner and outer molds, completing the mold reassembly. At the concrete pouring station, a type F robotic arm identifies the pre-reserved concrete cavity (6) using visual recognition and performs the concrete pouring operation. At the mold sealing station, a type B robotic arm uses an electromagnetic gripper to restore the annular upper sealing plate (8), followed by an inflation and sealing operation. At the mold delivery station, a type A robotic arm completes the mold movement and transfer operation.
[0064] The pneumatic components include an automatic pneumatic interface a and an automatic pneumatic interface b. The mold disassembly station is equipped with an automatic pneumatic interface a that can connect to the air valve of the airbag 4 to perform an exhaust operation, causing the airbag 4 to contract and thus releasing its radial expansion lock between the outer mold 1 and the inner mold 2. The mold closing station is equipped with an automatic pneumatic interface b, which is used to inject gas into the airbag 4, causing it to inflate to a predetermined pressure, thereby closing the mold injection port and achieving radial locking of the inner and outer molds.
[0065] Example 3:
[0066] The main content of this embodiment is the same as that of embodiment 2, except that the dwell time of the annular conveyor at each working position is controlled between 10 seconds and 600 seconds.
[0067] Example 4:
[0068] The main content of this embodiment is the same as that of embodiment 2 or 3, wherein the annular conveying mechanism adopts an annular conveyor belt, a chain conveyor, an annular roller conveyor, or an intermittently driven rotary table.
[0069] Example 5:
[0070] The main content of this embodiment is the same as any one of embodiments 2 to 4. The annular conveying mechanism is arranged at at least one end of the concrete centrifugal molding production line and is connected to the concrete centrifugal molding production line through a transfer robotic arm to receive molded products and send out the poured molds.
[0071] Example 6:
[0072] This embodiment is similar in content to any one of embodiments 2-5. The mold receiving station is located at the entrance of the production line and is equipped with a positioning device and sensors for accurately locating the molded product transferred from upstream equipment. The mold disassembly station group is subdivided into two sub-stations. First is the collar removal station, equipped with a multi-degree-of-freedom robotic arm and special clamps, used to grasp and remove the mold clamps 3. Next is the mold separation station, which has a three-dimensionally movable automatic pneumatic interface for precisely connecting to the air valve of the mold's central airbag 4 and releasing its internal pressure; simultaneously, another robotic arm, after the air pressure is released, grasps the handles on each segment of the outer mold 1, removes them, and separates them from the inner mold. The component removal station is equipped with a flexible gripper robotic arm with adjustable clamping force or a vacuum suction cup robotic arm for smoothly removing the concrete component that has loosened from the inner mold 2 and placing it on the conveyor line leading to the curing area. The mold reassembly station integrates multiple collaborative robotic arms. First, the robotic arm grabs and assembles the cleaned inner mold 2 (after automatic spraying) into a ring. Then, the airbag 4 is placed into the central cavity of the inner mold. Next, the outer mold 1 is grabbed and assembled into a ring around the inner mold. Finally, the robotic arm retrieves the clamp 3 from the feed tray and installs it in place, locking the mold. The concrete pouring station is equipped with a high-precision quantitative pouring machine and its moving gantry. Once the mold is in place, the pouring head automatically descends and aligns with the pre-drilled hole at the top of the inner mold 2, completing the concrete pouring. The mold sealing station again uses the automatic pneumatic interface to connect to the air valve of the airbag 4 and inflate it. The inflated airbag 4 pushes the annular sealing plate at its top downwards, tightly sealing the pouring hole. The mold delivery station is located at the production line exit and has a positioning and standby area. A transfer robotic arm waits here to grab and remove molds that have completed pouring and are waiting to return to the upstream process.
[0073] All workstations are centrally controlled and scheduled. The circular conveyor can move in a stepping or continuous uniform speed to ensure that the operation rhythm of each workstation is synchronized.
[0074] Example 7:
[0075] This embodiment provides a typical application of embodiments 2-6. A concrete centrifugal molding production line is arranged horizontally for centrifugal rotation molding of molds. The annular mold processing production line of this invention is arranged at the discharge end of the centrifugal line. Two large gantry robotic arms are respectively responsible for taking the molded products that have completed initial setting from the centrifugal line at the mold receiving station, and placing the newly poured molds back to the starting end of the centrifugal line at the mold delivery station. The two production lines are driven independently but controlled in a linked manner, forming a complete production closed loop of molding-processing-remolding.
[0076] Example 8:
[0077] This embodiment provides applications of embodiments 2-6, see also... Figure 8This embodiment includes two sets of centrifugal molding production lines and two sets of fully automated circulating processing production lines for annular molds. The two sets of centrifugal molding production lines are parallel, straight-flowing lines. The flow directions of the two sets of centrifugal molding production lines are opposite. After concrete is poured into the production mold, it is placed on the centrifugal molding production line for centrifugal rotation and longitudinal movement. The fully automated circulating processing production lines for annular molds are respectively arranged at both ends of the centrifugal molding production lines. By reusing the molds, the mold turnaround time can be shortened, and seamless connection between mold disassembly and mold assembly can be achieved.
[0078] In actual production, depending on the capacity requirements, one or more circular production lines can be flexibly combined with one or more centrifugal production lines.
[0079] Example 9:
[0080] This embodiment provides a concrete component production process for a fully automated circulating processing line with an annular mold as described in any one of Embodiments 2 to 6, including the following steps:
[0081] S1 Mold Receiving: The molded product, which has been initially set in the upstream concrete forming process, is placed at the mold receiving station of the circular conveyor mechanism by a transfer robotic arm.
[0082] S2 Mold Disassembly: The annular conveyor mechanism sequentially sends the molds to the mold disassembly station, automatically removes the external clamps 3, releases the pressure of the internal airbags 4, and separates the outer mold 1.
[0083] S3 Component Removal: The mold is sent to the component removal station, and the formed concrete component is automatically removed from the inner mold 2.
[0084] S4 Mold Reassembly: The separated inner and outer mold components are sent to the mold reassembly station, where the inner mold 2 and outer mold 1 are automatically reassembled above the bottom sealing plate. The airbag 4 is placed in the middle, and the clamp 3 is installed.
[0085] S5 Concrete Pouring: The reconstructed mold is sent to the concrete pouring station, and freshly mixed concrete is automatically poured into the mold.
[0086] S6 Mold Closing: The mold is sent to the mold closing station, and air is automatically inflated into the airbag 4 to close the mold injection port.
[0087] S7 Mold Delivery: The completed mold is delivered to the mold delivery station, and then transferred back to the upstream concrete forming process by a transfer robotic arm.
[0088] This embodiment realizes the standardization and automation of the mold processing flow, completely changing the traditional intermittent and discrete production mode.
