Description

Technical Field

[0001] The invention relates to the technical field of concrete test block demoulding, and in particular to a concrete test block demoulding machine and a control method thereof. Background Art

[0002] The quality of concrete directly determines the safety and stability of the building. According to GB 50164-2011 "Concrete Quality Control Standard", in order to ensure the quality of the building and the division of responsibilities, the relevant properties of the concrete test blocks must be retained and tested before the concrete finished products leave the factory. The existing retention and testing of concrete test blocks in concrete mixing plants is relatively complicated, requiring a lot of manpower to complete the sampling, maintenance, performance testing, concrete batch data recording and other processes of concrete. The overall automation of the testing process is extremely low, and the costs and errors caused by manual labor are also the problems faced by concrete industry manufacturers. The realization of automation and intelligence of concrete laboratories is an inevitable trend in the development of the industry.

[0003] Among them, during the demoulding after the concrete solidifies and the subsequent constant temperature curing in the preparation process of concrete test blocks, the solidified test blocks need to be manually taken out of the mold and transferred to the workshop for cleaning. The cleaning process requires the burrs on the side walls of the test blocks to be manually trimmed and polished, and finally transported to the constant temperature curing area. The operation is difficult and easy to damage the concrete test blocks. Summary of the invention

DETAILED DESCRIPTION

[0056] Although the present invention can be easily embodied in different forms of embodiments, only some of the specific embodiments are shown in the drawings and will be described in detail in this specification. It should be understood that this description should be regarded as an exemplary illustration of the principles of the invention and is not intended to limit the invention to that described herein.

[0057] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the present invention, rather than implying that each embodiment of the present invention must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0058] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front and back) used to explain the structure and movement of various elements of the present invention are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the description of the positions of these elements changes, the indications of these directions also change accordingly.

[0059] Figure 1 The schematic diagram of the structure of the concrete block demoulding machine is shown. Figure 2 Shows Figure 1 The structural diagram of the concrete block demoulding machine from another perspective. Figure 3 The schematic diagram of the structure of the first mold 2 is shown. Figures 1 to 3 The concrete block demoulding machine comprises a frame 1, a trimming device 3, a first mold 2, a second mold, a first conveying device 5, a second conveying device 8 and a material ejecting device 6. The trimming device 3 is arranged on the frame 1, and the trimming device 3 forms a trimming channel 31, and a first position 312 corresponds to the outside of a feeding end 311 of the trimming channel 31, and a second position 314 corresponds to the outside of a discharging end 313 of the trimming channel 31.

[0060] The first mold 2 has an opening 21 for placing a test block, and the first mold 2 is provided with a through hole 22 on the inner bottom surface corresponding to the opening 21. The first mold 2 can be used as an initial setting mold to place an initial setting concrete test block. The first conveying device 5 is configured to convey the first mold 2 to the first position 312, and make the opening 21 of the first mold 2 located at the first position 312 face and communicate with the feed end 311 of the trimming channel 31.

[0061] The second mold is also provided with an opening 21 for placing the test block. The second mold, as a curing mold, can place the test block after trimming and deburring, which is convenient for the test block to be transported, and is transferred through an external transfer component for subsequent watering and curing of the test block. The second conveying device 8 is configured to convey the second mold to the second position 314, and make the opening 21 of the second mold located at the second position 314 face and communicate with the discharge end 313 of the trimming channel 31.

[0062] The first mold 2 can be placed on the transfer component and automatically loaded to the first position 312 by the first conveying device 5, or directly placed on the first conveying device 5. The second mold can be placed on the transfer component and automatically loaded to the second position 314 by the second conveying device 8, or directly placed on the second conveying device 8. In addition, the transfer component can be an AGV trolley.

[0063] The pushing device 6 has a pushing end 621 that can be displaced from the first position 312 to the second position 314 along the length direction of the trimming channel 31, and the pushing end 621 can penetrate the through hole 22 and abut against the test block of the first mold 2 located at the first position 312. Then the pushing end 621 is displaced and pushes the test block of the first mold 2 located at the first position 312 into the trimming channel 31, so that the circumferential side wall of the test block is trimmed by the trimming channel 31, and then the test block is pushed into the second mold located at the second position 314.

[0064] Specifically, when the periphery of the test block needs to be demolded, the concrete test block demolding machine uses the first conveying device 5 to align the opening 21 of the first mold 2 with the feed end 311 of the trimming channel 31, and the second conveying device 8 aligns the opening 21 of the second mold with the trimming channel 31 and the discharge end 313, and then the ejecting device 6 pushes the test block in the first mold 2 out, and passes through the trimming channel 31 for trimming before entering the second mold. The inner wall of the trimming channel 31 fits the outer shape of the test block, so that when the test block passes through the trimming channel 31, the burrs and flash on the side of the test block can be removed under the action of friction.

[0065] The concrete test block demoulding machine of the present application can simultaneously realize the trimming and transfer functions of the test block during the demoulding process of the concrete test block, saving working procedures, reducing the handling process, and improving production efficiency. At the same time, the trimmed test block side is smoother, which can reduce the stress error of subsequent pressure quality testing and improve the standardization of the test block.

[0066] like Figure 1As shown, a plurality of casters 11 are provided at the bottom of the frame 1 so that the concrete block demoulding machine can be moved and is convenient for users to use flexibly. In addition, a guide mechanism 12 is provided at the lower part of the outer periphery of the frame 1 and above the corresponding casters 11. The guide mechanism 12 can be a through groove extending horizontally, which can facilitate the positioning of the transfer components loaded with multiple first molds 2 and multiple second molds to the corresponding working positions respectively. The guide mechanism 12 can provide auxiliary position adjustment for the transfer components.

[0067] like Figure 3 As shown, the first mold 2 is provided with three openings 21 arranged in sequence, and the inner bottom surface of the opening 21 is provided with a through hole 22 so that the ejection end 621 can extend therein. The structure of the second mold can refer to the structure of the first mold 2, and the same number of openings 21 are correspondingly provided so that the test blocks can be accommodated one-to-one in the second mold. In actual work, the number and position of the openings 21 on the first mold 2, the number and position of the feed ends 311 of the trimming channel 31, and the number and position of the ejection ends 621 correspond one to one. The number and position of the openings 21 on the second mold correspond to the number and position of the discharge ends 313 of the trimming channel 31. In addition, the first mold 2 may also be provided with only one or more openings 21.

[0068] Figure 4 The structural schematic diagram shows the trimming frame 32 facing the discharge end 313 of the trimming channel 31. Figure 5 FIG. 3 shows a cross-sectional view of the trimming frame 32 cut along a direction passing through a plurality of trimming channels 31. Figure 4 and Figure 5 The trimming frame 32 is arranged on the frame 1, and the trimming frame 32 encloses at least one trimming channel 31, and the axial ends of the trimming channel are respectively a feed end 311 and a discharge end 313. The position corresponding to the feed end 311 is a first position 312. The position outside the discharge end 313 is a second position 314. The trimming frame 32 is provided with a trimming portion 315 at a position corresponding to the trimming channel 31, and the trimming portion 315 is protruded relative to the inside of the trimming channel 31.

[0069] Specifically, the first mold 2 at the first position 312 abuts against the end face of the trimming frame 32 facing the first position 312, and the second mold at the second position 314 abuts against the end face of the trimming frame 32 facing the second position 314. The inner peripheral wall of the trimming channel 31 fits and corresponds to the outer peripheral wall of the test block. By providing a trimming portion 315 on the inner wall of the trimming frame 32 corresponding to the trimming channel 31, the test block passing through the trimming channel 31 can remove burrs under the action of the raised trimming portion 315, and then fit the inner wall of the trimming channel 31 to further remove small burrs, thereby improving the trimming effect of the test block. In this embodiment, the test block is square, and the cross-sectional shape of the trimming channel 31 can be square, that is, it has four inner side walls connected end to end in sequence. It should be noted that the raised position of the trimming portion 315 can always ensure that the test block can pass through the trimming channel 31 smoothly.

[0070] The trimming portion 315 may be located at the feed end 311 of the trimming channel 31, or at a position other than the two ends of the trimming channel 31. The trimming portion 315 is disposed on at least one inner side wall of the trimming channel 31, and may be disposed on one, two or more inner side walls of the trimming channel 31. The trimming portion 315 may be in the form of a strip or a sheet-like protrusion. If the trimming portion 315 is in the form of a strip, the trimming portion 315 may extend in a direction perpendicular to the length of the trimming channel 31, or may be at an angle to the length of the trimming channel 31. In addition, the strip-shaped trimming portion 315 may be in a structure along a straight line, a broken line, an arc line or a wavy line, and the present embodiment does not impose any specific restrictions on the specific shape, position and layout of the trimming portion 315.

[0071] Furthermore, the trimming frame 32 includes a plurality of partitions 323, a first side plate 321 and a second side plate 322 that are arranged opposite to each other, wherein the partitions 323 are connected between the first side plate 321 and the second side plate 322, and the plurality of partitions 323 are arranged opposite to each other in sequence. The trimming channel 31 is formed between two adjacent partitions 323, the first side plate 321 and the second side plate 322.

[0072] Specifically, a square trimming channel 31 is formed by the plate structure, the length direction of the trimming channel 31 extends in a straight line, and the inner wall of the trimming channel 31 fits the outer wall of the test block, thereby improving the trimming effect of the test block. Multiple trimming channels 31 are arranged in sequence along the same direction, corresponding to the positions of the openings 21 of the first mold 2 and the second mold.

[0073] In addition, the trimming channel 31 surrounded by the trimming frame 32 extends in the horizontal direction. Specifically, the first side plate 321 and the second side plate 322 can be both arranged in the horizontal direction, and the two are arranged at intervals up and down, and the corresponding partition 323 extends vertically. In some other embodiments, the first side plate 321 and the second side plate 322 can also be arranged vertically, and the two are arranged at intervals in the horizontal direction, and the partition 323 extends horizontally. In addition, the trimming channel 31 can also be extended in an angled direction relative to the horizontal direction. However, the trimming channel 31 is generally not arranged to extend in the vertical direction to prevent the test block in the first mold 2 or the test block on the second mold from falling directly into the trimming channel 31 under the action of gravity. If the trimming channel 31 is set to a vertical or relatively inclined extension direction, it is necessary to set a movable part on the trimming channel 31 to carry and drive the test block to move.

[0074] The first side plate 321 , the second side plate 322 and the partition plate 323 can be connected by welding or formed by bending a sheet metal. The first side plate 321 and the second side plate 322 are disposed on the frame 1 .

[0075] Furthermore, Figure 6 This is a structural schematic diagram of the trimming frame 32 in this embodiment. The trimming frame 32 also includes a trimming strip 325. The trimming strip 325 is connected between the first side panel 321 and the second side panel 322. The trimming strip 325 is arranged on the side of the partition 323 close to the first position 312. The relative two side edges of the trimming strip 325 extend into the interior of the two adjacent trimming channels 31 respectively.

[0076] Specifically, the number of the trimming strips 325 corresponds to the partitions 323 one by one, the arrangement direction of the plurality of trimming channels 31 is the first direction, the thickness of the trimming strips 325 in the first direction is greater than the thickness of the partitions 323 along the first direction, and the trimming strips 325 on opposite sides along the first direction can protrude toward two adjacent trimming channels 31. The trimming strips 325 in this embodiment are the trimming portions 315 described above.

[0077] In this embodiment, the trimming channel 31 surrounded by the trimming frame 32 extends in the horizontal direction, and the trimming strips 325 extend in the vertical direction, so that each trimming channel 31 forms bulges on both sides of the feed end 311 in the horizontal direction. The trimming strips 325 on both sides can remove the burrs on the two horizontally opposite pressure surfaces of the test block, and then further remove the flash after the burrs fall through the inner wall of the trimming channel 31, so that the pressure surfaces on both sides of the test block are smoothed. After the two pressure surfaces of the test block are trimmed, the position of the pressure surface needs to withstand the pressure of the pressure tester during the pressure test, and needs to be completely fitted with the anvil of the pressure tester. The trimming of the pressure surface can make the pressure surface more uniform, improve the standardization of the test block, and reduce the stress error of the pressure quality test. After the two opposite pressure surfaces of the test block are squeezed, the remaining free surface of the test block will be broken, and the staff can observe the cracks on the test block through the camera, and then judge the force strength of the test block.

[0078] In order to improve the positioning stability of the first mold 2 at the first position 312 and the second mold at the second position 314, and ensure that the test block can be smoothly demolded from the first mold 2 and pass through the trimming frame 32 into the second mold, in some embodiments, a first support 33 is provided on the side of the trimming frame 32 close to the first position 312. A second support 34 is provided on the side of the trimming frame 32 close to the second position 314. The first support 33 can be used to support the first mold 2 located at the first position 312 to maintain the stability of the first mold 2. The second support 34 can be used to support the second mold located at the second position 314 to maintain the stability of the second mold.

[0079] The first support 33 and the second support 34 may be selected as rods, blocks or plates, etc., as long as the first support 33 can at least position or limit the bottom or two horizontally opposite sides of the first mold 2, and the second support 34 can at least position or limit the bottom or two horizontally opposite sides of the second mold.

[0080] Furthermore, the first support member 33 in this embodiment includes two first support plate units 331 arranged at intervals in the horizontal direction. The two first support plate units 331 are arranged at intervals, and can be staggered with the first transfer mechanism 51 on the first conveying device 5 to reduce interference between the devices.

[0081] Specifically, the two first support plate units 331 can be disposed at the bottom of the first position 312 at two opposite sides along the first direction, and can be supported on the bottom of the first mold 2 at the first position 312 at two opposite sides along the first direction.

[0082] In some embodiments, the first support plate unit 331 includes a bottom plate and a side plate that are staggered. The bottom plate extends horizontally and can support the bottom surface of the first mold 2. The side plate extends vertically and can limit the movement of the first mold 2 in the first direction. At the same time, the first mold 2 is positioned in height and limited on both sides along the first direction. In fact, the bottom plate and the side plate can be set separately, or the two can be connected to each other to form an L-shaped structure.

[0083] In addition, the opening 21 of the first support plate unit 331 on the side corresponding to the entry direction of the first mold 2 is gradually expanded, so as to guide the first mold 2 and facilitate the alignment of the first mold 2. Specifically, when the first mold 2 enters the first position 312 from top to bottom, the side plates on the two support plate units are inclined upward in a direction away from each other. When the first mold 2 enters the first position 312 horizontally, the side plates on the two support plate units extend in a direction away from the trimming frame 32 and away from each other.

[0084] The second support member 34 in this embodiment includes two second support plate units 341 spaced apart in the horizontal direction, which can reduce interference with the first conveying device 5 and other structures. In addition, the structure of the second support plate unit 341 can refer to the above description of the first support plate unit 331, and can also be an L-shaped plate structure, which will not be described in detail here.

[0085] Reference Figure 7 The first conveying device 5 includes a first transfer mechanism 51, and the first transfer mechanism 51 includes a first supporting platform 511. The first supporting platform 511 can be used to support the first mold 2, and can drive the first mold 2 to flip 90 degrees and reset, so that the first mold 2 with the opening 21 facing upward located on the first supporting platform 511 can flip to the first position 312. Specifically, the trimming channel 31 extends in the horizontal direction. Correspondingly, the feed end 311 and the discharge end 313 of the trimming channel 31 both have the opening 21 facing horizontally. The first mold 2 with the opening 21 facing upward is loaded onto the first supporting platform 511, and the first mold 2 is positioned and supported by the first supporting platform 511, and the first mold 2 is driven to flip, so that the first mold 2 can flip from the state with the opening 21 facing upward to the state with the opening 21 facing horizontally, and enter the first position 312, at which time the opening 21 of the first mold 2 faces the feed end 311 of the trimming channel 31. The test block is initially solidified in the first mold 2 with the opening 21 facing upward, and the first mold 2 is turned 90° by the first conveying device 5, so that the solidified test block can be demolded from the first mold 2 under the action of the ejection end 621, enter the trimming channel 31 for trimming, and then enter the second mold with the opening 21 also facing horizontally. In addition, the first transfer mechanism 51 can also drive the first mold 2 to turn 180° or other angles.

[0086] In addition, the first conveying device 5 can also be a conveyor belt, a pushing component that can push the first mold 2, or an upper and lower conveying component that can drive the first mold 2 to move up and down, etc. The direction of the opening 21 of the first mold 2 remains unchanged during the process of being brought from the first conveying device 5 to the first position 312.

[0087] The part of the first supporting platform 511 used to support the first mold 2 may be a flat plate or blocks arranged at the bottom of two opposite sides of the first mold 2. When the first supporting platform 511 supports the first mold 2 with the opening 21 facing upward, the supporting surface of the first supporting platform 511 in contact with the first mold 2 faces upward, and when the first supporting platform 511 supports the first mold 2 with the opening 21 facing the feed end 311 of the trimming channel 31, the supporting surface of the first supporting platform 511 also faces the feed end 311 of the trimming channel 31.

[0088] Furthermore, the first conveying device 5 includes a first supporting platform 511, a rotating driving member 512 and at least one rotating arm 513, wherein the output end of the rotating driving member 512 is synchronously connected to one end of the rotating arm 513, and the first supporting platform 511 is synchronously arranged at the other end of the rotating arm 513. The rotating arm 513 swings under the action of the rotating driving member 512, so that the first supporting platform 511 can achieve a relatively large position switching, thereby driving the first mold 2 to be transported a certain distance, and the first mold 2 can be switched back and forth between the loading position of the concrete block demoulding machine and the first position 312 under the action of the first conveying device 5. Two rotating arms 513 can be provided to improve the connection stability of the first supporting platform 511.

[0089] In addition, the first transfer mechanism 51 may also only include the first supporting platform 511 and the rotating driving member 512, and the rotating driving member 512 rotates and drives the first supporting platform 511, so that the first supporting platform 511 rotates and drives the opening 21 of the first mold 2 thereon to adjust the direction. The rotating driving member 512 is arranged on the frame 1, and can be a rotating cylinder or a motor.

[0090] In order to improve the positioning stability of the first mold 2 on the first supporting platform 511, baffles 514 are provided on opposite sides of the first supporting platform 511 in the rotation direction. The baffles 514 extend in the direction away from the rotating arm 513 and protrude from the first supporting platform 511. A limiting space 515 capable of positioning the first mold 2 is constructed between the baffles 514 on both sides and the first supporting platform 511.

[0091] Specifically, the baffle 514 includes a first baffle 514 and a second baffle 514, which are respectively arranged on opposite sides of the first supporting platform 511 in the direction of rotation. When the first supporting platform 511 flips the first mold 2 with the opening 21 facing upward to the first position 312, the first baffle 514 can prevent the first mold 2 from falling under the action of gravity, and the first baffle 514 can be supported on the bottom of the first mold 2 located at the first position 312. When the first supporting platform 511 flips the first mold 2 at the first position 312 back to the position with the opening 21 facing upward, the baffle 514 on the other side can prevent the first mold 2 from falling out of the first supporting platform 511 under the action of inertia, and the first mold 2 can remain positioned in the limiting space 515, so that the first transfer mechanism 51 can continuously switch the position of the first mold 2.

[0092] In some specific embodiments, the extension length of the second baffle 514 in the direction away from the rotating arm 513 is less than the extension length of the first baffle 514 in the direction away from the rotating arm 513, so that it is convenient for the staff or other automatic loading structures to load the first mold 2 onto the first supporting platform 511, thereby reducing interference. Moreover, the first baffle 514 and the second baffle 514 can be a whole plate, or composed of plates arranged at intervals.

[0093] Combination Figure 7 and Figure 8 The end face of the first supporting platform 511 is provided with a protrusion 516 corresponding to the shape and position of the through hole 22, and the protrusion 516 is provided with a guide hole 5161, wherein: when the first mold 2 is located at the first position 312, the top material end 621 can penetrate into the through hole 22 through the guide hole 5161.

[0094] Specifically, when the first mold 2 is placed on the first supporting platform 511, the protrusion 516 penetrates into the through hole 22 of the first mold 2, and the guide hole 5161 is connected with the through hole 22. When the first mold 2 is located at the first position 312, the ejection end 621 of the ejection device 6 can penetrate into the through hole 22 through the guide hole 5161, and can pass through the through hole 22 to abut against the test block in the first mold 2. The number of the protrusions 516 matches the number of the through holes 22 of the first mold 2.

[0095] In some specific embodiments, the opening 21 of the guide hole 5161 close to the end of the rotating arm 513 gradually expands to guide the ejection end 621 and facilitate the insertion of the ejection end 621. The outer diameter of the end of the protrusion 516 facing away from the rotating arm 513 gradually decreases to facilitate the protrusion 516 to penetrate into the through hole 22 of the first mold 2.

[0096] Reference Fig. 9 and Fig.10The first conveying device 5 further includes a first clamping and conveying mechanism 52, which is used to clamp and convey the first mold 2 with the test block placed on it to the first supporting platform 511, or to remove the empty first mold 2 from the first supporting platform 511. This enables the first mold 2 to be automatically loaded onto the first supporting platform 511.

[0097] Furthermore, the first clamping and conveying mechanism 52 includes a clamping jaw 521, a switching platform 522, a first driving member 523 and a second driving member 524. The clamping jaw 521 can grasp or release the first mold 2. The switching platform 522 is staggered up and down with the first supporting platform 511. The driving end of the first driving member 523 is connected to the clamping jaw 521, and the first driving member 523 is configured to drive the clamping jaw 521 to move above the switching platform 522. The driving end of the second driving member 524 is connected to the switching platform 522, and the second driving member 524 is configured to drive the switching platform 522 to move up and down, so that the switching platform 522 can transfer the first mold 2 on the clamping jaw 521 downward to the first supporting platform 511.

[0098] Specifically, after the clamp 521 grabs the first mold 2, it moves to the top of the switching platform 522 through the first driving member 523. The switching platform 522 moves up to the bottom of the first mold 2 under the action of the second driving member 524, and is higher than the height of the first supporting platform 511. The clamp 521 releases the first mold 2, so that the first mold 2 is placed on the switching platform 522. Then the second driving member 524 drives the switching platform 522 to move down and move to, so that the first mold 2 is switched to the first supporting platform 511. The first mold 2 on the clamp 521 can be smoothly transferred to the first supporting platform 511 through the switching platform 522, so as to avoid the vibration and sudden drop of the first mold 2 after the clamp 521 is released, and protect the integrity of the first mold 2 and the test block.

[0099] Conversely, after the test block in the first mold 2 is demoulded, the first transfer device flips and resets the first supporting platform 511, and then lifts the first mold 2 to a position where the clamp 521 can be clamped through the switching platform 522, so that the clamp 521 can move the first mold 2 out under the action of the first driving member 523. The clamp 521 can be formed by two clamp arms that can be relatively far away and close to each other through the clamp 521 cylinder or through a linear driving member such as a cylinder. The first driving member 523 and the second driving member 524 are arranged on the frame 1, and can be a driving device such as a cylinder, a motor screw, etc.

[0100] It should be noted that if Fig.10As shown, the switching platform 522 and the first supporting platform 511 are staggered up and down, so that the switching platform 522 can avoid the position of the first supporting platform 511 during the up and down displacement process. In addition, the first supporting platform 511 does not completely cover the bottom surface of the first mold 2, ensuring that the switching platform 522 can face upward to part of the bottom surface of the first mold 2, so that the switching platform 522 can stably receive the first mold 2 from the clamp 521 or the first supporting platform 511.

[0101] In this embodiment, two switching platforms 522 are provided, and the two switching platforms 522 are disposed on opposite sides of the first supporting platform 511 . Specifically, the two switching platforms 522 are disposed on both sides of the first supporting platform 511 along the first direction.

[0102] Reference Fig.11 The ejection device 6 includes a third driving member 61 and an ejector pin 62. The third driving member 61 is arranged on the frame 1. The ejector pin 62 is synchronously connected to the output end of the third driving member 61 and can move back and forth along the length direction of the trimming channel 31. The ejector pin 62 extends in a direction close to the trimming device 3, and the end of the ejector pin 62 close to the trimming device 3 is the ejection end 621.

[0103] The ejector pin 62 extends toward the feed end 311 of the trimming channel 31. In this embodiment, the ejector pin 62 extends in the horizontal direction. Three ejector pins 62 are arranged in sequence along the first direction and correspond to the feed end 311 openings 21 of the three trimming channels 31 in the trimming frame 32. The third driving member 61 is arranged on the frame 1, and the third driving member 61 can be a driving device such as a telescopic cylinder or a motor screw.

[0104] Reference Figure 1 An escape space is formed between the rotating arm 513 of the first transfer mechanism 51 and the first supporting platform 511, and the ejecting device 6 is located in the escape space. When the first supporting platform 511 transfers the first mold 2 to the first position 312, the ejecting end 621 of the ejector pin 62 can just face the through hole 22 of the first mold 2 and the guide hole 5161 of the protrusion 516 on the first supporting platform 511.

[0105] Combination Figure 1 and Fig.12 The concrete test block demoulding machine further includes a waste bag 7, which is arranged on the frame 1 and below the trimming device 3, and is used to collect the residual material of the test block after being trimmed by the trimming device 3. The waste bag 7 has a collection port with an opening 21 facing upward, and the inner bottom surface of the waste bag 7 extends obliquely downward, so that the residual material can be led out of the device. In addition, a blowing structure can also be provided on the frame 1, which can blow the debris in the trimming channel 31 corresponding to the trimming frame 32 into the waste bag 7.

[0106] In this embodiment, the second conveying device 8 includes a second transfer mechanism 81, and the second transfer mechanism 81 includes a second supporting platform 811. The second supporting platform 811 can be used to support the second mold, and can drive the second mold to flip 90° and reset, so that the second mold with the opening 21 facing upward on the second supporting platform 811 can be flipped to the second position 314. The second conveying device 8 includes a second clamping mechanism 82, and the second clamping mechanism 82 is used to remove the second mold with the test block placed on it from the second supporting platform 811, or to clamp the empty second mold to the second supporting platform 811. In addition, the second transfer mechanism 8 can also drive the second mold to flip 180° or other angles.

[0107] The second mold with its opening 21 facing upward is loaded onto the second supporting platform 811. The second mold is positioned and supported by the second supporting platform 811, and the second mold is driven to flip over, so that the second mold can flip from a state with its opening 21 facing upward to a state with its opening 21 facing horizontally, and enter the second position 314. At this time, the opening 21 of the second mold faces the discharge end 313 of the trimming channel 31.

[0108] In this embodiment, the second transfer mechanism 81 includes a second supporting platform 811, a rotating driving member 512 and at least one rotating arm 513, the output end of the rotating driving member 512 is synchronously connected to one end of the rotating arm 513, and the second supporting platform 811 is synchronously arranged at the other end of the rotating arm 513. The second supporting platform 811 is provided with baffles 514 on both sides opposite to the rotation direction, and the baffles 514 extend in the direction away from the rotating arm 513 and protrude from the second supporting platform 811.

[0109] The second clamping and conveying mechanism 82 may include a clamping jaw 521, a switching platform 522, a fourth driving member, and a fifth driving member. The clamping jaw 521 can grasp or release the second mold. The driving end of the fourth driving member is connected to the clamping jaw 521, and the fourth driving member is configured to drive the clamping jaw 521 to move above the switching platform 522. The driving end of the fifth driving member is connected to the switching platform 522, and the fifth driving member is configured to drive the switching platform 522 to move up and down, so that the switching platform 522 can transfer the second mold on the clamping jaw 521 downward to the second supporting platform 811.

[0110] The structure of the second transfer mechanism 81 can refer to the specific structure of the first transfer mechanism 51. The specific structure of the second clamping mechanism 82 can be the same as the first clamping mechanism 52, which will not be described in detail here. Figure 1 and Figure 2The second conveying device 8 and the first conveying device 5 are symmetrically arranged on both horizontal sides of the trimming device 3. In addition, the second conveying device 8 can also be a conveyor belt, a material pushing member capable of pushing the second mold, or a vertical conveying member capable of driving the second mold to move up and down, etc. The opening 21 of the second mold always remains in the direction from the second conveying device 8 to the second position 314.

[0111] Reference Fig.13 The present invention also discloses a control method for a concrete test block demoulding machine, which is applied to the above-mentioned concrete test block demoulding machine, and the specific steps are as follows:

[0112] S1. The first conveying device 5 conveys the first mold 2 with the test block placed thereon to the first position 312. Specifically, the first conveying device 5 clamps the first mold 2 with the opening 21 facing upward, flips it 90°, and places it in the first position 312, so that the opening 21 of the first mold 2 is connected to the trimming channel 31.

[0113] S2, the second conveying device 8 conveys the unloaded second mold to the second position 314. Specifically, the second conveying device 8 clamps the second mold with the opening 21 facing upward, flips it 90 degrees, and then places it in the second position 314, so that the opening 21 of the second mold is connected to the trimming channel 31.

[0114] S3, the ejection device 6 is started, so that the ejection end 621 pushes the test block from the first mold 2 into the trimming channel 31 through the through hole 22, and the test block enters the second mold after being trimmed by the trimming channel 31.

[0115] S4, the first conveying device 5 moves the first mold 2 out of the first position 312 after demolding, which specifically includes: the first conveying device 5 turns the first mold 2 at the first position 312 over 90 degrees and clamps it out, so that the opening 21 of the first mold 2 is restored to face upward.

[0116] S5, the second conveying device 8 moves the second mold loaded with the test block out of the second position 314. Specifically, the second conveying device 8 turns the second mold loaded with the test block at the second position 314 by 90° and clamps it out, so that the opening 21 of the second mold is restored to face upward.

[0117] The control method of the concrete test block demoulding machine of the present application can realize the automation of test block demoulding on the same equipment, and in the initial setting demoulding process of the test block, the automatic trimming and automatic transfer functions of the test block are realized at the same time, the automatic loading and unloading of the first mold 2 and the second mold are completed, and the demoulding and transportation of the concrete test block are realized intelligently, which saves working procedures and improves production efficiency. At the same time, the side of the test block after trimming is smoother, which can reduce the stress error of subsequent pressure quality detection and improve the standardization degree of the test block.

[0118] Before the concrete block demoulding machine works, the trolley loaded with the first mold 2 is moved to the loading position of the first conveying device 5, and the trolley loaded with the second mold is moved to the loading position of the second conveying device 8. The first conveying device 5 can clamp the first mold 2 on the trolley, and the second conveying device 8 can clamp the second mold on the trolley. In addition, the concrete block demoulding machine can also be pushed to the loading and unloading positions of the first mold 2 and the second mold.

[0119] The specific implementation process is as follows:

[0120] Step 1: The AGV trolley loaded with the first mold 2 and the second mold arrives at the opposite sides of the concrete test block demoulding machine respectively;

[0121] Step 2: The first clamping device reaches the position of the first mold 2 under the push of the first driving member 523 (i.e., the translation cylinder), and the cylinder on the clamping jaw 521 moves, driving the clamping jaw 521 to clamp the first mold 2, and then the first driving member 523 drives the clamping jaw 521 to return to the position above the switching platform 522; the second driving member 524 (i.e., the lifting cylinder) is lifted to the bottom surface of the first mold 2, the clamping jaw 521 is opened, and the first mold 2 falls onto the supporting plate of the switching platform 522, and the second driving member 524 is lowered, so that the first mold 2 falls onto the first supporting platform 511 of the first transfer mechanism 51;

[0122] Step 3: The second clamping device reaches the position of the second mold under the push of the fourth driving member (i.e., the translation cylinder), and the cylinder on the clamping jaw 521 moves, driving the clamping jaw 521 to clamp the second mold, and then the fourth driving member drives the clamping jaw 521 to return to the position above the switching platform 522; the fifth driving member (i.e., the lifting cylinder) is lifted to the bottom surface of the second mold, the clamping jaw 521 is opened, and the second mold falls onto the supporting plate of the switching platform 522, and the fifth driving member is lowered, so that the second mold falls onto the second supporting platform 811 of the second transfer mechanism 81;

[0123] Step 4: The rotary driving member 512 (i.e., the rotary cylinder) of the first rotating mechanism rotates to drive the first mold 2 located on the first supporting platform 511 to rotate to the first position 312, and the first mold 2 is located on the first supporting member 33 of the trimming frame 32, and the opening 21 of the first mold 2 is horizontally opposite to the feeding end 311 of the trimming channel 31;

[0124] Step 5: The rotary driving member 512 (i.e., the rotary cylinder) of the second rotating mechanism rotates to drive the second mold on the second supporting platform 811 to rotate to the second position 314. The second mold is located on the second supporting member 34 of the trimming frame 32, and the opening 21 of the second mold is horizontally opposite to the discharge end 313 of the trimming channel 31.

[0125] Step 6: The third driving member 61 (i.e., the ejecting cylinder) moves, driving the ejector pin 62 to sequentially pass through the guide hole 5161 of the first supporting platform 511 and the through hole 22 at the bottom of the first mold 2, and then eject the concrete test block out of the first mold 2. The ejection process of the test block passes through the trimming frame 32. The trimming strips 325, the partition plate 323, the first side plate 321 and the second side plate 322 on the trimming frame 32 can trim the test block with residual materials. The ejector pin 62 continues to push the test block to the second mold, and the residual materials fall into the waste bag 7.

[0126] Step 7: The rotating driving member 512 of the first transfer device drives the first supporting platform 511 to return to its original position, and the second driving member 524, the first driving member 523 and the clamping claw 521 cooperate with each other to lift the first mold 2 back to the AGV trolley;

[0127] Step 8: The rotating driving member 512 of the second transfer device drives the second supporting platform 811 to reset, and the fifth driving member, the fourth driving member and the clamping claw 521 cooperate with each other to lift the second mold back to the AGV trolley;

[0128] Step nine: After the test blocks on the plurality of first molds 2 are demolded in sequence, the empty first mold 2 and the second mold with the test blocks are transported to a designated storage location by an AGV vehicle.

[0129] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
