Description

Technical Field

[0001] The present invention relates to a production device and a production method for precast concrete components, and in particular to a demoulding device and a demoulding method for precast concrete components. Background Art

[0002] For small prefabricated components, traditional production methods generally use single-piece molds made of plastic, and demolding is achieved by manually knocking the mold. This is time-consuming and labor-intensive, and the mold is easily damaged, affecting the quality of subsequent components. The mold also has a short service life. In some new small prefabricated component production lines, in order to increase production and improve efficiency, molds with integrated multiple cavities are often used. One mold can produce multiple components at a time, and then demolding is achieved through a demolding device. Existing demolding devices have the problem of some components being unable to be demolded or even damaged. They can only be used for components of the same type or components using the same demolding method. They cannot provide a suitable demolding method for different types of components, have a small scope of application, and poor versatility. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a demoulding device for precast concrete components which has a simple structure and can be demoulded upward or downward.

[0004] The present invention further provides a demoulding method for the above-mentioned precast concrete component demoulding device.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

The mold conveying mechanism, the demoulding mechanism and the mold limiting component are all arranged on the rotating mechanism. The rotary drive mechanism is connected to the rotating mechanism. The mold limiting component is located above the mold conveying mechanism.

[0012] As a further improvement of the above technical solution: the demoulding mechanism includes a lifting component that is detachably connected to the component mold.

[0013] A demoulding method for the above-mentioned precast concrete component demoulding device comprises the following steps:

[0014] S1. The component mold is transported to the mold conveying mechanism. The mold limiting component fixes the component mold. The rotary drive mechanism drives the rotary mechanism to rotate 180 degrees so that the prefabricated component in the component mold faces downward.

[0015] S2. The transfer trolley moves to the bottom of the component mold, and the component tray rises until the distance between the topmost prefabricated component on the component tray and the component mold reaches the set value. The demoulding mechanism removes the prefabricated component from the component mold and places it on the component tray;

[0016] S3. The component tray descends, the transfer trolley moves out from under the component mold, the rotary drive mechanism drives the rotary mechanism to reset, the mold limiter releases the component mold, and the component mold falls onto the mold conveying mechanism, which then outputs the demolded component mold.

[0017] S4. Repeat steps S1 to S3 until all components are demoulded.

[0018] As a further improvement of the above technical solution: in step S1, the component mold is conveyed to the mold conveying mechanism, and the lifting drive member drives the pressing block to lift up and press the component mold against the mold limiting component;

[0019] In step S2, the transfer trolley moves to the bottom of the component mold, and the component tray rises until the distance between the current top prefabricated component on the component tray and the component mold reaches the set value. The lifting drive member drives the pressing block to press down the ejector rod on the component mold, and the prefabricated component is ejected from the component mold and falls onto the component tray;

[0020] In step S3, the component tray descends, the transfer trolley moves out from under the component mold, the rotary drive mechanism drives the rotary mechanism to reset, and the lifting drive member drives the pressing block to reset so that the demoulded component mold falls on the mold conveying mechanism.

[0021] As a further improvement of the above technical solution: in step S2, the vibrator vibrates to release the prefabricated component from the component mold and drop it onto the component tray.

[0022] As a further improvement of the above technical solution: in step S2, the lifting component lifts the component mold upward, then releases the component mold, and the component mold falls onto the mold limiting component.

[0054] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] Example 1

[0056] Figures 1 to 6 and Figure 24 An embodiment of a demoulding device for precast concrete components of the present invention is shown. The demoulding device for precast concrete components of this embodiment includes a mold conveying mechanism 1, a demoulding mechanism 2, a rotating mechanism 3, a rotating drive mechanism 4, a mold limiting component 5, and a transfer trolley 6. The mold conveying mechanism 1, the demoulding mechanism 2, and the mold limiting component 5 are all arranged on the rotating mechanism 3. The rotating drive mechanism 4 is connected to the rotating mechanism 3. The mold limiting component 5 is located above the mold conveying mechanism 1. The transfer trolley 6 is provided with a liftable component tray 61. The mold limiting component 5 can be, for example, a limiting rib, a plurality of blocks arranged at intervals along the conveying direction of the mold conveying mechanism 1, etc., which can cooperate with the demoulding mechanism 2 to achieve the fixation of the component mold 7 on the rotating mechanism 3; the component tray 61 can be lifted and lowered by, for example, a commonly used hydraulic scissors support.

[0057] The demoulding device for precast concrete components comprises a mold conveying mechanism 1 for carrying the component mold 7 and outputting the empty component mold 7 after demoulding; a demoulding mechanism 2 for lifting the component mold 7 upwards so that the component mold 7 and the mold limiting component 5 are pressed against each other for subsequent overall rotation; and a push rod 72 for pushing the component mold 7 downwards to realize demoulding of the precast component 71; and a rotating mechanism 3 can drive the component mold 7, the mold conveying mechanism 1, the demoulding mechanism 2, the mold limiting component 5 and the like to rotate as a whole under the drive of the rotating driving mechanism 4, so that the precast component 71 faces downwards for easy removal. The demoulding mechanism 2 cooperates with the push rod 72 on the component mold 7 to reliably remove the prefabricated component 71. The transfer trolley 6 is used to carry the removed prefabricated components 71 and stack them. The overall structure is simple, reliable, and easy to use, which is conducive to the smooth removal of the prefabricated components 71. It has a high degree of automation and high production efficiency. The concrete prefabricated component demoulding device is suitable for component molds 7 with push rods 72 and deep mold cavities of the component molds 7, such as E-groove and U-groove prefabricated components 71.

[0058] Reference Figures 25 to 27Of course, in other embodiments, a track frame 8 can be further provided and a mobile trolley 81 can be provided on the track frame 8. The mobile trolley 81 is provided with a lifting mechanism 82, and the lifting mechanism 82 is provided with a plurality of component grabbing parts 83. The rotating mechanism 3 does not need to drive the component mold 7 to rotate, and can realize upward demoulding, so that the demoulding method of the equipment is more diversified and can be applied to different types of prefabricated component 71 products. The lifting mechanism 82 can be, for example, a screw nut pair, a hydraulic cylinder, a winch, etc. The component grabbing part 83 preferably adopts a vacuum suction cup and is equipped with a vacuum source. When the vacuum source is turned on, the vacuum suction cup can absorb and fix the prefabricated component 71. When the vacuum is disconnected, it can be separated from the prefabricated component 71, which is suitable for prefabricated components 71 with relatively flat surfaces. Of course, the component grabbing part 83 can also be a clamping claw, etc.

[0059] During demoulding, the demoulding mechanism 2 lifts up and presses the component mold 7 against the mold limiting component 5, and the mobile trolley 81 moves along the track frame 8 to drive the component grabbing component 83 to move above the component mold 7, and the lifting mechanism 82 drives the component grabbing component 83 to descend, and the component grabbing component 83 grabs and fixes the prefabricated component 71, and the demoulding mechanism 2 pushes the push rod 72 on the component mold 7 upward or the vibrator 23 vibrates, and at the same time, the lifting mechanism 82 drives the component grabbing component 83 to rise, and the prefabricated component 71 is removed from the component mold 7, and the demoulding mechanism 2 is reset to make the demoulded component mold 7 fall on the mold conveying mechanism 1, and the mold conveying mechanism 1 outputs the demoulded component mold 7, and at the same time, the mobile trolley 81 moves along the track frame 8 to drive the component grabbing component 83 to move above the component pallet 61, and the lifting mechanism 82 descends to stack the prefabricated components 71 on the component pallet 61, and the component grabbing component 83 releases the prefabricated components 71.

[0060] As a preferred technical solution, in this embodiment, the mold conveying mechanism 1 includes two parallel rows of conveyor chains 11, with the demolding mechanism 2 located between the two rows of conveyor chains 11. This facilitates the demolding mechanism 2 to lift or press down the component mold 7, resulting in a compact and rational layout. Of course, in other embodiments, two parallel rows of rollers or conveyor belts may also be used to convey the component mold 7.

[0061] As a preferred technical solution, in this embodiment, the demolding mechanism 2 includes a pressing block 21 and a lifting drive 22 connected to the pressing block 21. The pressing block 21 increases the coverage area of ​​the lifting drive 22, thereby pressing down all the push rods 72 as a whole, thereby simultaneously performing demolding. The lifting drive 22 can be, for example, a hydraulic cylinder, an air cylinder, an electric push rod, a screw-nut pair, or the like, as long as it can achieve the lifting and lowering of the pressing block 21.

[0062] As a preferred technical solution, in this embodiment, the rotating mechanism 3 includes a rotating frame 31, a supporting wheel 33 provided on the side of the rotating frame 31, and a ring gear 32 provided on the rotating frame 31 for driving the rotating frame 31 to rotate. The mold conveying mechanism 1, the demoulding mechanism 2 and the mold limiting component 5 are all provided on the rotating frame 31. The rotating drive mechanism 4 includes a driving gear 41, and the driving gear 41 is engaged with the ring gear 32. During operation, the supporting wheel 33 provides support for the rotating frame 31, and the driving gear 41 rotates, thereby driving the ring gear 32 and the rotating frame 31 to rotate as a whole. The structure is simple and reliable, and the flipping is stable and smooth. Of course, in other embodiments, the supporting wheel 33 can also be used to directly drive the rotating frame 31 to rotate. The supporting wheel 33 can directly drive the rotating frame 31 to rotate by friction, or it can be driven to rotate by a transmission device such as a chain or belt. See Figure 28 Alternatively, a transmission chain 34, a belt, etc. may be provided on the rotating frame 31, and the rotation driving mechanism 4 may be provided with a driving sprocket 42, a driving pulley, etc. accordingly.

[0063] The demoulding method of the concrete precast component demoulding device of this embodiment includes the following steps:

[0064] S1. The component mold 7 is transported to the mold conveying mechanism 1. The lifting drive member 22 lifts the pressure block 21 to press the component mold 7 against the mold limiting member 5. The rotary drive mechanism 4 drives the rotary mechanism 3 to rotate 180° so that the prefabricated component 71 in the component mold 7 faces downward.

[0065] When the trolley 61 is in the state of being moved to the position below the mold 7, the pallet 61 is lifted and the distance between the uppermost prefabricated component 71 and the mold 7 reaches the set value. The lifting drive 22 drives the pressing block 21 to press down, and the push rod 72 on the mold 7 is pressed down. The push rod 72 pushes the prefabricated component 71 out of the mold 7 and onto the pallet 61. It should be noted that in the initial state, the pallet 61 does not carry any prefabricated components 71. At this time, the distance between the pallet 61 and the mold 7 reaches the set value. In each subsequent cycle, the next batch of prefabricated components 71 is stacked on the previous batch of prefabricated components 71. The height of the pallet 61 is reduced by the thickness of one prefabricated component 71, thereby ensuring that the height of the prefabricated component 71 is unchanged each time it is demoulded, and avoiding damage to the prefabricated component 71 caused by excessive demoulding height.

[0066] S3: The component tray 61 descends, the transfer trolley 6 moves out from under the component mold 7, the rotary drive mechanism 4 drives the rotary mechanism 3 to reset, and the lifting drive member 22 drives the pressing block 21 to reset, so that the demolded component mold 7 falls onto the mold conveying mechanism 1, and the mold conveying mechanism 1 outputs the demolded component mold 7;

[0067] S4. Repeat steps S1 to S3 until all component molds 7 are demoulded.

[0068] In this demoulding method, the demoulding mechanism 2 lifts the component mold 7 and presses it against the mold limiting component 5, so that the component mold 7 can rotate with the rotating mechanism 3. The rotating drive mechanism 4 drives the rotating mechanism 3 to rotate 180° as a whole, so that the prefabricated component 71 is arranged downward. The demoulding mechanism 2 cooperates with the push rod 72 on the component mold 7 to reliably remove the prefabricated component 71, reducing the component breakage rate. The transfer trolley 6 is used to carry the removed prefabricated components 71 and complete stacking, with a high degree of automation and high production efficiency. Of course, in other embodiments, a vacuum suction and lifting device or a clamping device can also be provided above the component mold 7. The vacuum suction and lifting device or the clamping device cooperates with the demoulding mechanism 2 below to perform demoulding. During the demoulding process, the rotating mechanism 3 does not need to rotate, so that the demoulding device has both upward demoulding and downward demoulding functions, so as to be suitable for components using different demoulding methods.

[0069] Example 2

[0070] Figures 7 to 14 as well as Figures 22 to 24 Another embodiment of the demoulding device for precast concrete components of the present invention is shown. This embodiment is substantially the same as the first embodiment, except that, in this embodiment, a lifting drive 22 serves as a lifting component for driving the component mold 7 to rise and fall. Furthermore, a telescopic latch 24 is provided on the demoulding mechanism 2 (specifically, a telescopic latch 24 is provided on the pressure block 21), and a slot 73 is provided on the component mold 7 to cooperate with the telescopic latch 24, thereby achieving a detachable connection between the two. This structure is simple and reliable. When the telescopic latch 24 extends into the slot 73, the demoulding mechanism 2 can drive the component mold 7 to rise. When the telescopic latch 24 retracts from the slot 73, the component mold 7 is impacted downward by gravity and falls onto the mold stopper 5. The precast component 71 can then be separated from the component mold 7 by inertia. This device is suitable for precast components 71 that are not convenient to vacuum lift or clamp. For example, hexagonal bricks, fences, fence posts, curbstones, etc. Of course, in other embodiments, other lifting components (not shown in the figure) can also be provided, and the detachable connection method can also be clamping, vacuum adsorption, etc., which can drive the component mold 7 to rise and fall and then release the component mold 7 to achieve impact demolding.

[0071] The demoulding method of the concrete precast component demoulding device of this embodiment includes the following steps:

[0072] S1. The component mold 7 is transported to the mold conveying mechanism 1. The lifting drive member 22 lifts the component mold 7 and presses it against the mold limiting member 5. The rotary drive mechanism 4 drives the rotary mechanism 3 to rotate 180 degrees so that the prefabricated component 71 in the component mold 7 faces downward.

[0073] S2, the transfer trolley 6 moves to the bottom of the component mold 7, the component tray 61 rises until the distance between the current top prefabricated component 71 on the component tray 61 and the component mold 7 reaches the set value, the telescopic latch 24 extends into the card slot 73, the lifting drive 22 drives the component mold 7 to rise to the set height, the telescopic latch 24 retracts from the card slot 73, the component mold 7 falls onto the mold limiting component 5, the prefabricated component 71 is released from the component mold 7 by inertia and falls on the component tray 61, and the lifting drive 22 drives the pressing block 21 presses down to press the component mold 7 and the mold limiting component 5 tightly together; it should be noted that in the initial state, the component tray 61 does not carry any prefabricated components 71. At this time, the distance between the component tray 61 and the component mold 7 reaches the set value. In each subsequent cycle, the next batch of prefabricated components 71 is stacked on the previous batch of prefabricated components 71. The height of the component tray 61 is reduced by the thickness of one prefabricated component 71, thereby ensuring that the height of the prefabricated components 71 remains unchanged each time they are demoulded, avoiding damage to the prefabricated components 71 caused by excessive demoulding height.

[0074] S3: The component tray 61 descends, the transfer trolley 6 moves out from under the component mold 7, the rotary drive mechanism 4 drives the rotary mechanism 3 to reset, and the lifting drive member 22 drives the pressing block 21 to reset so that the demolded component mold 7 falls onto the mold conveying mechanism 1, and the mold conveying mechanism 1 outputs the demolded component mold 7;

[0075] S4. Repeat steps S1 to S3 until all component molds 7 are demolded. In this demolding method, the demolding mechanism 2 lifts the component mold 7 and presses it against the mold limiting component 5, so that the component mold 7 can rotate with the rotating mechanism 3. The rotary drive mechanism 4 drives the rotating mechanism 3 to rotate 180 degrees as a whole, so that the prefabricated component 71 is arranged downward. The demolding mechanism 2 cooperates with the telescopic latch 24 to achieve impact demolding. The prefabricated component 71 can be reliably removed by inertia. The transfer trolley 6 is used to carry the removed prefabricated components 71 and complete the stacking. It has a high degree of automation and high production efficiency. It is suitable for prefabricated components 71 that are not convenient to be lifted or clamped by vacuum suction, such as hexagonal bricks, fences, fence posts, curbstones, etc.

[0076] Example 3

[0077] Figures 15 to 24Another embodiment of the demoulding device for precast concrete components of the present invention is shown. The demoulding device for precast concrete components of this embodiment is basically the same as that of the second embodiment, except that, in this embodiment, a vibrator 23 is provided on the pressing block 21, and the pressing block 21 and the vibrator 23 are driven up and down by a lifting drive 22. The vibration of the vibrator 23 can loosen the precast component 71 within the component mold 7, ultimately achieving smooth demoulding. At the same time, when the component mold 7 is cleaned after demoulding, the vibration of the vibrator 23 can specifically cause concrete residues adhering to the surface of the component mold 7 and in the gaps to fall off, thereby improving the cleaning effect. Of course, in other embodiments, the vibrator 23 can also be directly mounted on the rotating frame 31.

[0078] The demoulding method of the concrete precast component demoulding device of this embodiment includes the following steps:

[0079] S1. The component mold 7 is transported to the mold conveying mechanism 1. The lifting drive 22 drives the pressing block 21 to lift the component mold 7 and press it against the mold limiting component 5. At the same time, the vibrator 23 contacts the component mold 7. The rotary drive mechanism 4 drives the rotating mechanism 3 to rotate 180°, so that the prefabricated component 71 in the component mold 7 faces downward.

[0080] S2, the transfer trolley 6 moves to the bottom of the component mold 7, and the component tray 61 rises until the distance between the current topmost prefabricated component 71 on the component tray 61 and the component mold 7 reaches the set value, and the vibrator 23 vibrates to remove the prefabricated component 71 from the component mold 7 and drops it on the component tray 61, and then stops vibrating; it should be noted that in the initial state, the component tray 61 does not carry any prefabricated components 71. At this time, the distance between the component tray 61 itself and the component mold 7 reaches the set value. In each subsequent cycle, the next batch of prefabricated components 71 is stacked on the previous batch of prefabricated components 71, and the height of the component tray 61 rises by a thickness value of one prefabricated component 71, thereby ensuring that the height of the prefabricated component 71 remains unchanged each time it is demoulded, and avoiding damage to the prefabricated component 71 caused by excessive demoulding height;

[0081] S3: The component tray 61 descends, the transfer trolley 6 moves out from under the component mold 7, the rotary drive mechanism 4 drives the rotary mechanism 3 to reset, and the lifting drive member 22 drives the pressing block 21 and the vibrator 23 to reset, so that the demolded component mold 7 falls onto the mold conveying mechanism 1, and the mold conveying mechanism 1 outputs the demolded component mold 7;

[0082] S4. Repeat steps S1 to S3 until all component molds 7 are demoulded.

[0083] In this demoulding method, the demoulding mechanism 2 lifts the component mold 7 and presses it against the mold limiting component 5, so that the component mold 7 can rotate with the rotating mechanism 3. The rotating drive mechanism 4 drives the rotating mechanism 3 to rotate 180° as a whole, so that the prefabricated component 71 is arranged downward. The vibrator 23 on the demoulding mechanism 2 vibrates, which can reliably remove the prefabricated component 71 and avoid damaging the prefabricated component 71. The transfer trolley 6 is used to carry the removed prefabricated components 71 and complete stacking. It has a high degree of automation and high production efficiency, and is suitable for prefabricated components 71 that are not convenient to use vacuum suction and lifting, such as hexagonal bricks, fences, fence posts, curbstones, etc.

[0084] Further, referring to Example 2, in other embodiments, in step S2, if there is a prefabricated component 71 that has not been ejected, the vibrator 23 stops vibrating, the telescopic pin 24 extends into the slot 73, the demoulding mechanism 2 drives the component mold 7 to rise, the telescopic pin 24 retracts from the slot 73, the component mold 7 falls onto the mold limiting component 5, and the prefabricated component 71 that has not been ejected is ejected from the component mold 7 by inertia and falls onto the component tray 61. The demoulding mechanism 2 presses down to press the component mold 7 against the mold limiting component 5, that is, vibration demoulding is performed first, and then impact demoulding is performed. The two demoulding methods are combined to ensure that all prefabricated components 71 are ejected.
