Description

Technical Field

[0001] This invention belongs to the technical field of concrete component production, specifically relating to a small-scale automated production line for components. Background Technology

[0002] The production process of small concrete components is usually as follows: a concrete placing machine is used to fill and pour concrete into the forming mold and vibrate it to make it dense. A forklift is used to transport the mold to the curing area. After the conditions for demolding are met, the mold is demolded. The empty mold is transferred to a conveyor equipment, sprayed with a release agent, and then transported to the concrete placing and vibration area to wait for production. This production operation method has obvious advantages over traditional manual operation. It has a high degree of automation and good safety. However, due to the small size of small components (such as hexagonal slope protection) and the large demand, conventional production lines face the problem of high labor repetition, which is not conducive to improving production efficiency and reducing production costs.

[0057] like Figure 1 As shown, an automated production line for small components is used to produce small concrete components, such as hexagonal slope protection. The production line includes a prefabrication production line and a mold recycling line extending in parallel. A steam curing workshop is provided at the same end of the prefabrication production line and the mold recycling line. The steam curing workshop can quickly cure the concrete components, thereby improving the concrete curing speed and efficiency.

[0058] In order to improve production efficiency by prefabricating multiple concrete components at the same time, the jig 3 used in this application has multiple molds arranged in an array. The openings of the multiple molds point to the same side of the jig 3. The jig 3 is a cuboid frame welded from galvanized square steel, and the six molds are distributed in the jig 3.

[0059] Preferably, each jig frame 3 has six molds arranged in three rows and two columns.

[0060] The precast production line includes a flipping device 1, a material placing device 2, and a stacking device 4 arranged sequentially along a conveyor line. The conveyor line is a conveyor belt, conveyor roller, or other conveying equipment, which connects the various production devices together to achieve assembly line production. The flipping device 1 is used to flip the jig 3 to be placed, so that the mold opening inside the jig 3 faces upward. Then, it is transported to the material placing device 2 through the conveyor line. The material placing device 2 is used to place concrete into the mold inside the jig 3. The material placing device 2 accurately places concrete into each mold through the material placing port. Then, the conveyor line transports the jig 3 to the stacking device 4. The stacking device 4 is used to stack multiple jigs 3. After stacking, the multiple jigs 3 are transferred to the steam curing workshop by forklift for curing, thereby reducing the number of repetitive tasks and improving production efficiency.

[0061] The mold recycling line consists of a stacking device 5, a turning device 1, and a demolding device 7 arranged sequentially along the conveyor line. After curing, the mold frames 3 are transported to the stacking device 5 by forklift. The stacking device 5 conveys multiple mold frames 3 one by one along the conveyor line after steam curing. At the turning device 1, the mold frames 3 are turned over so that the mold openings on the mold frames 3 face downwards for demolding. The demolding device 7 is located between the precast production line and the mold recycling line. It is used to demold the mold frames 3 and then transfer the demolded mold frames 3 to the conveyor line in front of the turning device 1 of the precast production line. At this time, the turning device 1 of the precast production line turns over so that the mold openings face upwards for the next round of small component precasting. The stacking device is used to stack and store the demolded concrete components. The stacking device is a robotic arm 6, which is equipped with suction cups corresponding to six concrete components to carry them by suction.

[0062] In this embodiment, the stacking device 4 and the destabilizing device 5 are the same device, the difference being that they achieve stacking and destabilizing respectively through opposite operating methods.

[0063] The following provides a detailed description of stacking device 4, such as Figure 2-3As shown, it includes a conveying mechanism, a stacking rack 503, and a lifting platform 506. The conveying mechanism is used to convey the mold frame 3 for mold transfer. A stacking station is provided at the end of the conveying mechanism. After the mold frame 3 is conveyed to the stacking station by the conveying mechanism, the mold frame 3 is stacked by the cooperation of the stacking rack 503 and the lifting platform 506, so as to realize the synchronous handling of multiple mold frames 3. The four legs of the stacking rack 503 are correspondingly straddling the stacking station. The middle of the stacking rack 503 forms a stacking space directly above the corresponding stacking station, which can accommodate multiple stacked mold frames 3.

[0064] Limiting members A504 are provided on both sides of the stacking rack 503 corresponding to the width direction of the conveying mechanism. The limiting members A504 extend and retract within the stacking space. The lifting platform 506 is located directly below the stacking station. It can be lifted upward through the conveying mechanism and then the jig 3 is lifted above the limiting member A504. At this time, the limiting member A504 extends into the stacking space and can form a stop limit at the bottom of the jig 3, thereby limiting the jig 3 in the longitudinal direction. After the next jig 3 is conveyed to the stacking station, the lifting platform 506 lifts the jig 3 upward. The next jig 3 touches the lower surface of the previous jig 3. Then the limiting member A504 exits the stacking space. The lifting platform 506 continues to lift. The next jig 3 reaches the limiting member A504. At this time, the limiting member A504 extends into the stacking space again to limit the next jig 3. This process is repeated to achieve the stacking of multiple jigs 3.

[0065] At least the conveying mechanism corresponding to the stacking station includes a conveyor frame 501 and a conveyor roller group. The conveyor roller group extends linearly, and two conveyor roller groups are located on both sides of the conveyor frame 501. The distance between the two conveyor roller groups is adapted to the width of the jig 3. The gap between the two conveyor roller groups is used for the lifting platform 506 to lift. The length of the lifting platform 506 is greater than the length of the jig 3, so that the jig 3 can be effectively lifted.

[0066] In this embodiment, the conveyor roller assembly includes a mounting groove A508 and an idler roller 507. The upper end of the mounting groove A508 is open, and the length of the idler roller 507 is adapted to the opening width of the mounting groove A508. The two ends of the idler roller 507 are rotatably connected to the two sides of the mounting groove A508 through bearings. The mounting groove A508 extends along the conveying direction of the conveyor frame 501, and multiple idler rollers 507 are equidistantly assembled in the mounting groove A508. The sidewall of the idler roller 507 protrudes upward from the upper end of the mounting groove A508.

[0067] In this embodiment, one end of the idler roller 507 is connected to a driven sprocket. The driven sprockets of the idler rollers 507 in the same conveyor roller group are driven by the same chain, and the stepper motor A509 is connected to the chain through the drive sprocket.

[0068] In this embodiment, the limiting member A504 includes two pins that are slidably mounted on the side wall of the stacking rack 503. The pins pass through the side wall of the jig 3 and extend into its inner wall, thereby forming a stop with the frame of the jig 3 to stop and limit the jig 3.

[0069] A telescopic rod with a drive pin is provided on the outside of the stacking rack 503. Two pins are provided on each side of the stacking rack 503, and the two pins are located at the two ends of the length direction of the jig 3 respectively.

[0070] In this embodiment, the stacking rack 503 has a feed inlet and a discharge outlet. The stacking rack 503 has a discharge outlet on one side corresponding to the conveying direction of the conveying mechanism, and a feed inlet on the other side. Positioning members A505 above the conveying mechanism are provided on both sides of the discharge outlet. Positioning members A505 can limit the jig 3 to prevent the jig 3 from flowing out of the stacking station.

[0071] The installation methods of positioning component A505 and limiting component A504 are basically the same. When the forklift needs to remove the tire frame 3, positioning component A505 moves outward from the unloading port to make way for the tire frame 3 to be removed.

[0072] In this embodiment, lifting columns are provided below the lifting platform 506. The lifting columns are hydraulic cylinders, and the four lifting columns correspond to the four corners of the lifting platform 506 to achieve lifting.

[0073] In this embodiment, the stacking rack 503 is equipped with a corresponding sensor switch for the jig 3. The sensor switch can be a Hall element or an infrared sensor, thereby sensing whether the jig 3 has completely entered the stacking station.

[0074] In an optional embodiment, the flipping device 1 includes a rotating frame, a clamping mechanism, and a drive ring 101, such as Figure 4-8 As shown, the rotating frame is a columnar frame. Specifically, multiple connecting rods B109 are welded between the two drive rings 101 to form a columnar frame. A base B108 is set on the flow path of the frame 3. Drive roller groups are correspondingly provided on opposite sides inside the rotating frame. The two sets of drive roller groups are symmetrical about the center of the rotating frame. The gap between the two sets of drive roller groups is greater than the thickness of the frame 3. Thus, when the frame 3 flows to the rotating frame via the conveyor belt, the drive roller groups drive the drive roller groups to pass through the rotating frame.

[0075] The two sides of the same drive roller group are fixed to the two drive rings 101 by the receiving groove 118. The opening of the receiving groove 118 faces the inside of the rotating frame, thereby rotatably connecting the guide roller B107 and receiving the transmission chain.

[0076] Two clamping mechanisms correspond to two drive roller groups respectively. Specifically, the clamping mechanisms are set on the side of the drive roller groups that are far apart from each other. The clamping mechanisms have clamping members 104B that pass through the drive roller groups. The clamping members 104B can pass through the drive roller groups, thereby clamping or releasing the tire frame 3 through the relative movement of the clamping members 104B. The tire frame 3 can be restricted during the flipping process.

[0077] Two drive rings 101 are located at both ends of the rotating frame. A first drive member corresponding to the drive ring 101 is provided on the base B108 to drive the rotating frame to roll on the base B108 and drive the frame 3 to flip.

[0078] The carriage 3 flows along the conveyor path via a conveyor belt. In the initial state, both drive roller groups inside the rotating frame are kept horizontal. At this time, one of the drive roller groups (for easy distinction, the lower drive roller group in the initial state is named the first roller group, and the other drive roller group is named the second roller group) is on the same horizontal plane as the conveyor belt. When the carriage 3 moves into the rotating frame, it is clamped by two oppositely arranged clamping mechanisms. Then, the rotating frame can be driven to rotate by the first drive member, thereby causing the carriage 3 to flip. At this time, the horizontal plane of the other drive roller group (the second roller group) is on the same horizontal plane as the conveyor belt. The second roller group is then started to move the carriage 3 to the conveyor belt behind the rotating frame for subsequent flow.

[0079] In this embodiment, the drive ring 101 protrudes outward from the outer peripheral surface of the rotating frame. An arc-shaped groove corresponding to the drive ring 101 is provided above the base B108. The angle corresponding to the arc-shaped groove should not be less than 90°. The outer peripheral surface of the drive ring 101 is provided with gear teeth. The first drive member meshes with the outer gear teeth of the drive ring 101 through the drive gear. The first drive member can be a stepper motor, which can drive the drive ring 101 to rotate precisely.

[0080] The drive roller assembly includes multiple guide rollers B107 that are equidistantly distributed along the axial direction of the rotating frame. The guide rollers B107 are spaced apart, and the gap between two adjacent guide rollers B107 is adapted to the diameter of the guide rollers B107. A sprocket is provided at one end of each of the multiple guide rollers B107. The second drive unit B103 drives the multiple guide rollers B107 synchronously through a transmission chain.

[0081] In this embodiment, each clamping mechanism includes multiple clamping members 104B, with three clamping members 104B in total. Thus, one clamping member 104B is respectively provided at both ends and the middle part of the jig frame 3. The clamping member 104B is a strip structure, the length of which is adapted to the length of the guide roller B107 and is directly opposite the gap between the guide rollers B107. The clamping member 104B is driven by a third driving member B102, which is an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder. Guide posts B105 are provided at both ends of the clamping member 104B, and the guide posts B105 are slidably mounted on the mounting truss.

[0082] In this embodiment, the rotating frame is provided with guide rods 106 corresponding to both sides of the tire frame 3 in the middle. The guide rods 106 are located at the midpoint between the two drive roller groups and their length is adapted to the length of the rotating frame. The front end of the guide rods 106 is bent to both sides to form an outwardly expanding guide opening. A sensing mechanism is provided at the rear end of the guide rods 106 to detect the position of the tire frame 3.

[0083] The sensing mechanism includes a dial 110 and a fourth driving member B111. The dial 110 is rotatably connected to the rear end of the guide rod 106. The diameter of the dial 110 is basically the same as the diameter of the guide post. Two paddles corresponding to the end frames of the tire frame 3 are distributed on the outer periphery of the dial 110. The paddles are fan-shaped plates at 90°. As the tire frame 3 moves forward, it can be driven to rotate by the push of the support posts B113 on both sides of the end of the tire frame 3. As the dial 110 rotates, it determines that the tire frame 3 has reached the designated position.

[0084] Alternatively, by actively rotating and actuating the end of the frame 3, the frame 3 can continue to move axially along the rotating frame. During the flow of the frame 3, there will be a certain gap between the drive roller group and the conveyor belt flowing behind. In order to make the frame 3 enter the conveyor belt more smoothly, the end of the frame 3 can be actively rotated and actuated, specifically the support column B113 at the corner of the frame 3.

[0085] The fourth driving component B111 is connected to the dial 110 to drive the dial 110 to rotate actively, thereby giving the tire frame 3 a certain initial power. The fourth driving component B111 is the third stepper motor.

[0086] In this embodiment, the specific position of the dial 110 is detected by the sensor B112. During the rotation of the dial 110, one of the sector plates is pushed by the tire frame 3 to move. When the sector plate is rotated to the position (90°), the fourth drive unit B111 is activated, so that the other sector plate pushes the tire frame 3 forward. The active rotation angle is also 90°. At this time, the dial 110 returns to the initial position so as to detect the next tire frame 3.

[0087] Specifically, the position of the dial 110 is sensed by the sensor B112. The sensor B112 is located on the outside of the guide rod 106. The sensor B112 can be an infrared sensor, a position sensor, or an angle sensor, etc. When the sensor B112 is facing the dial, it detects the relative position of the dial. The sensor B112 is connected to the control center.

[0088] The control center is a PLC control center, and is connected to the first drive unit, the second drive unit B103, the third drive unit B102 and the fourth drive unit B111, thereby enabling automated control reversal.

[0089] In this embodiment, the dial 110 is rotatably connected to the rotating shaft B115, and a ratchet 116 is provided between the rotating shaft B115 and the dial 110. The rotating shaft B115 passes through the guide rod 106 and is correspondingly connected to the fourth drive member B111.

[0090] Specifically, the dial 110 has a mounting hole in the middle corresponding to the rotating shaft B115. A ratchet 114 is provided inside the mounting hole. The outer wall of the rotating shaft B115 has a mounting groove with a ratchet 116 that slides radially along the rotating shaft B115 inside. A spring 117 is provided at the bottom of the mounting groove so that the ratchet 116 has the potential energy to drive the ratchet 114, thereby forming the ratchet 116 structure.

[0091] A dial 110 is provided on each of the guide rods 106 located on both sides of the rotating frame, and the dials 110 on the two guide rods 106 are symmetrical to each other.

[0092] A flat surface corresponding to the dial 110 is provided above the guide rod 106. A through hole corresponding to the rotating shaft B115 is provided inside the guide rod 106. The rotating shaft B115 passes through the guide rod 106 and is connected to the third stepper motor B.

[0093] In one optional embodiment, the fabric feeding device includes a hopper C204, a feeding track, a feeding trough 201, and a driving component, such as... Figure 9-10 The upper end of the hopper C204 is open, and the lower end of the hopper C204 is provided with a material distribution chamber. After the concrete passes through the material distribution chamber, it is discharged from the lower material distribution port 217. The material distribution chamber is equipped with a spiral guide rod 212. The inner cavity of the material distribution chamber is adapted to the spiral guide rod 212. The rotation of the spiral guide rod 212 drives the concrete to be discharged from the material distribution port 217. When not rotating, a certain degree of sealing is formed, thereby ensuring accurate material distribution.

[0094] Two fabric openings 217 are provided below the fabric cavity, and the fabric openings 217 correspond one-to-one with each row of molds on the die frame 3.

[0095] The feeding track extends obliquely to the upper end of the hopper C204. A feeding trough 201 is slidably mounted on the feeding track. A driving component is provided at the upper end of the feeding track. The driving component drives the feeding trough 201 to move along the feeding track. The upper end of the feeding trough 201 is inclined towards the hopper C204 and extends between the two guide rails C202. A feeding port 216 is opened on the side wall of the hopper C204 corresponding to the lower part of the feeding trough 201. A baffle 215 is hinged to the lower edge of the feeding port 216. The baffle 215 opens the feeding port 216 to unload the material.

[0096] Guide rails C202 are provided on both sides of the feeding track. Slide grooves extending along their length are provided on the opposite sides of the two guide rails C202. A first roller that slides above the two guide rails C202 is provided on the outer wall of both sides of the feeding groove 201. Slide columns C213 are provided in the middle and lower part of both sides of the baffle 215. The two slide columns C213 extend into the two slide grooves on both sides respectively. When the slide column C213 is located in the slide groove, the baffle 215 is limited to block the feeding port 216.

[0097] An opening / closing station 211 is provided on the chute, located above and extending towards the hopper C204. When the sliding column C213 passes the opening / closing station 211, under the influence of the internal pressure of the feeding trough 201, the sliding column C213 will rotate around the hinge point towards the opening / closing station 211 to open the feeding port 216. As the feeding trough 201 moves further upward, the baffle 215 continues to rotate downward under the action of gravity, thereby guiding the internal concrete into the hopper C204. When the feeding trough 201 falls back, the baffle 215 is stopped from rotating by the opening / closing station 211 and closes the feeding port 216.

[0098] In this embodiment, the opening / closing station 211 is an extension of the chute, and its shape is a right-angled triangle. The corresponding hypotenuse connects to the chute, and the length of its base plate is not less than the distance between the sliding column C213 and the hinge point of the baffle 215, thereby ensuring that the baffle 215 can be fully opened. The end of the sliding column C213 is provided with a pulley corresponding to the chute.

[0099] In this embodiment, a conveyor belt C205 is provided below the material feeding port 217 for conveying the mold of the concrete component. Position sensors are provided on both sides of the conveyor belt C205 to detect the position of the jig 3, thereby determining whether the mold is aligned with the material feeding port 217.

[0100] In this embodiment, the spiral guide rod 212 extends along the width direction of the conveyor belt C205, so as to synchronously feed material to a row (no less than two) of molds in the width direction, and start the third stepper motor to realize the sequential feeding of material to multiple rows of molds on the jig 3.

[0101] In this embodiment, the fabric feeding chamber is formed by a guide tube adapted to the spiral guide rod 212. A strip-shaped guide port corresponding to the inner cavity of the hopper C204 is provided on the guide tube. The driving component is a second stepper motor C206. A main shaft C208 extending along its width is provided above the feeding track. The drive shaft of the second stepper motor C206 is connected to the main shaft C208 via chain drive, gear drive, or belt drive. Wheels C207 corresponding to both sides of the feeding trough 201 are provided at both ends of the main shaft C208. The wheel C207 drives the feeding trough 201 via a traction rope 209. A second roller C214 slidably mounted in a groove is provided in the portion of the feeding trough 201 extending between the two guide rails C202. Position sensors are also provided at both ends of the guide rails C202 to detect the travel position of the feeding trough 201.

[0102] In an optional embodiment, the demolding device 7 includes a crossbeam C703, a lifting component C706, a demolding frame 707, and a clamp 708, see below. Figure 11-12 The crossbeam C703 spans between the prefabrication production line and the mold recycling line. The prefabrication production line and mold recycling line consist of conveyor belts, conveyor rollers C701, etc. The demolding frame 707 is connected to the crossbeam C703 via a lifting rod. The lifting rod is slidably mounted on the crossbeam C703, allowing it to move between the two conveying mechanisms along the crossbeam C703. The demolding frame 707 is a steel truss structure, its shape conforming to and matching the shape of the mold 12 jig 3. Multiple jaws 70... 8 are respectively hinged to both sides of the demolding frame 707. The non-hinged ends of the claws 708 extend to both sides of the jig 3. The ends of the claws 708 are provided with bent portions extending squarely towards the jig 3. The claws 708 are driven by the drive component C711 to rotate towards the jig 3 and clamp the jig 3. After the jig 3 is gripped, the lifting rod shortens to lift the jig 3 upward. After the crossbar C703 is used to move to another conveying mechanism, the jig 3 is lowered and released by rotating the claws 708. The demolding frame 707 is reset to realize the demolding operation.

[0103] In this embodiment, two claws 708 are provided on each side of the demolding frame 707. The two claws 708 are hinged by the same hinge shaft C713. Hinge ears or hinge seats corresponding to the hinge shaft C713 extend outward on both sides of the demolding frame 707. After the hinge shaft C713 extends outward from the end face of the demolding frame 707, it is connected to a lever arm 710. The lever arm 710 extends radially along the hinge shaft C713. The lever arm 710 is connected to a driving member C711, which drives the claws 708.

[0104] In this embodiment, the driving component C711 is hinged to the end of the demolding frame 707, preferably any one of an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder, and the driving end of the driving component C711 is hinged to the lever arm 710.

[0105] The lifting rod is slidably mounted on the crossbeam C703 via a slide block C704, which is driven by a drive wheel C705 supported on the upper surface of the crossbeam C703.

[0106] Furthermore, multiple vibrators corresponding to the bottom of the small component mold 12 are provided below the demolding frame 707. The vibrators are connected to the lower surface of the demolding frame 707 by springs. During the downward movement of the demolding frame 707, the vibrators abut against the bottom of the mold 12 and demolding is assisted by vibration. The corresponding vibrators are connected to the controller.

[0107] In another alternative embodiment, a clamping fixture 8 is provided in front of the palletizing equipment, see [link to previous embodiment]. Figure 13 The system includes a conveying mechanism, a baffle D806, and a pusher plate 811. The conveying mechanism is used to convey concrete components 810, allowing the concrete components 810 to be conveyed sequentially to the rear of the conveying mechanism. A baffle D806 is provided at the corresponding stacking station of the conveying mechanism. The baffle D806 blocks multiple concrete components 810 to be arranged side by side in the conveying direction of the conveying mechanism, thus forming a close arrangement. Two pushers 811 are located on both sides of the width direction of the conveying mechanism. The two pushers 811 move relative to each other, so that multiple concrete components 810 are linearly arranged after being limited by the pushers 811, thus making multiple concrete components 810 linearly and closely arranged to correspond one-to-one with the suction cups on the robotic arm 6, thereby facilitating the robotic arm 6 to pick them up.

[0108] In this embodiment, in order to improve production efficiency, six concrete component 810 molds are arranged in an array within the jig 3, with the openings of multiple molds pointing to the same side of the jig 3, so that two rows of concrete components 810 are formed after being limited by the clamping tool 8 baffle D806 and the push plate 811.

[0109] The conveying mechanism includes a conveying frame D801 and a conveying roller D802. Guide plates D803 are provided on both sides of the conveying frame D801 in the width direction. The width of the guide plates D803 is adapted to the thickness of the concrete component 810. At least two guide posts D804 are provided on the outside of the push plate 811, so that the push plate 811 can slide along the width direction of the conveying frame D801 through the guide posts D804.

[0110] The push plate 811 is driven by the push rod D805, which is fixed to the outside of the guide plate D803. The driving end of the push rod D805 passes through the guide plate D803 and is fixedly connected to the push plate 811. The push rod D805 extends and retracts along the width of the conveyor frame D801, thereby driving the push plate 811. The push rod D805 can be a pneumatic rod or a hydraulic cylinder.

[0111] In this embodiment, the concrete component is a hexagonal slope protection. Multiple limiting members are provided on the inner side of the push plate 811. The inner side of the limiting members is adapted to the shape of the outer wall of the corresponding concrete component, which is used to limit the angle of the concrete component, avoid stacking errors caused by the angle deviation of the concrete component, and improve the stacking accuracy.

[0112] The concrete component 10 is a hexagonal slope protection. After demolding on the jig, one side of the concrete component 10 is parallel to the width direction of the conveying mechanism, so that the foremost concrete component 10 can be closely attached to the baffle D806 as it is conveyed.

[0113] The limiting member located in the middle of the push plate 811 is the first limiting member D808. There are multiple first limiting members D808, located at the joint of adjacent concrete components 10. Each first limiting member D808 has an inclined surface that is distributed in a V-shape and corresponds to two adjacent concrete components 10. The inclination angle of the inclined surface is the same as the angle of the outer wall of the concrete component 10 at the joint. After compression, the outer walls of the concrete components 10 at the joint are pressed together, thereby limiting the angle of the concrete components 10.

[0114] The two limiting members located at both ends of the push plate 811 are the second limiting members D807. The second limiting members D807 are used to limit the two concrete components 10 at the beginning and end. Specifically, the inclined surfaces on the two second limiting members D807 are inclined surfaces that are adapted to the outer wall of one side of the concrete components 10 at both ends. In this way, the two second limiting members D807 limit the multiple concrete components 10 in the conveying direction of the conveying mechanism, so that the multiple concrete components 10 are tightly attached to two rows.
