Description

Technical Field

[0001] The invention relates to the technical field of concrete test block manufacturing, in particular to a concrete test piece manufacturing device and method. Background Art

[0002] At present, concrete production enterprises, testing units and project construction parties need to make concrete specimens frequently. During the production process of concrete specimens, concrete is usually poured into a square mold, and then goes through processes such as vibration, stacking, curing, and demolding. Among them, the demolding process is a more critical step;

[0003] In the prior art, during the demoulding process of the concrete specimen, the blowing port of the demoulding air pump is generally inserted into the reserved port at the bottom of the square mold by hand, and then the mold is inverted, and the molded specimen is ejected from the square mold by the air pressure generated by the demoulding air pump. However, after a portion of the specimen is ejected from the mold, due to the gap between the specimen and the inner wall of the mold, the airflow blown in by the air pump is discharged along the gap, and it is difficult to generate further thrust on the specimen. At this time, there are two situations. One situation is that if the friction between the remaining part of the specimen and the inner wall of the mold is small, the specimen falls out of the mold under the action of its own gravity. The other situation is that the friction between the remaining part of the specimen and the inner wall of the mold is large and the specimen is still stuck in the specimen. It is necessary to manually pull the specimen out of the mold, and the pulling process is difficult. In addition, during the pulling process, concrete particles are stuck between the gap between the inner wall of the mold and the specimen, which further increases the difficulty of demoulding. The entire demoulding process is laborious and there is a risk of damage to the specimen that falls directly from the mold.

[0004] In addition, the existing methods for making concrete specimens usually involve manual production, manual handling, and manual demoulding, which have the problems of high labor intensity, unstable quality, and difficult process supervision. It is necessary to further improve the above-mentioned defects.

[0005] The above contents are only used to assist in understanding the technical solution of the present invention, and do not constitute an admission that the above contents are the closest prior art. Summary of the invention

[0006] The object of the present invention is to provide a concrete specimen production device and method to solve the problem that the existing concrete specimen demoulding process proposed in the above background technology requires manual labor to pull the specimen out of the mold, the pulling out process is difficult, and during the pulling out process, concrete particles are stuck in the gap between the inner wall of the mold and the specimen, which further increases the difficulty of demoulding. The entire demoulding process is time-consuming and laborious, and there is a risk of damage to the specimen that falls directly from the mold.

The upper rack and the lower rack are staggered to switch the rotation direction of the third spur gear.

[0051] In addition, the present invention also provides a method for preparing a concrete specimen, comprising the following steps:

[0052] Step 1: Mold on-line process: put the mold body and the tray on the production line, and raise them from the lifting station to be flush with the pouring and vibrating station. Then, the first barcode scanner automatically scans the QR code on the mold body, scans the concrete specimen to be poured, and inputs the information of the concrete strength, location, and pouring date of the concrete specimen, so that the QR code information of the mold body is assigned;

[0053] Step 2: concrete loading process: lower the lifting concrete placing boom and pour the concrete from the bucket truck into the hopper of the concrete placing boom;

[0054] Step 3, pouring and vibrating process: the concrete placing machine discharges the concrete from the spiral discharge port to the pouring and vibrating station through the shaftless discharge spiral configured at the bottom, and then the mold body after pouring and vibrating is sent to the smoothing station for smoothing;

[0055] Step 4: Palletizing process: Use the second barcode scanner to scan the mold body, and according to the content of the read QR code, lift the test piece to different channels according to different uses. At the same time, write the pouring time of concrete, and palletize it on the roller conveyor through the palletizer;

[0056] Step 5, resting process: resting the mold body after palletizing;

[0057] Step 6, depalletizing process: the system automatically calculates the resting time, and after the resting time is met, the pallets are automatically transported from the roller conveyor to the depalletizing machine for depalletizing;

[0058] Step 7: Demolding process: The third barcode scanner scans and identifies the QR code of the mold, reads the QR code information, confirms the purpose of the test piece, grabs it with a robot, flips it over, and puts it on the demoulding machine. Use compressed air to blow the test piece out of the mold body;

[0059] Step 8: Cleaning and spraying process: Use a robot to send the test piece into the coding machine for coding of the QR code and test piece information. Then, put the test piece into the stacking station for stacking. Send the pallet and mold body into the cleaning spraying machine. After cleaning the concrete residue, spray the demoulding machine, and return to the lifting station through the mold reflux roller line to enter the next cycle.

[0060] Compared with the prior art, the present invention has the following beneficial effects:

[0061] 1. The present invention supports the test piece in the initial demoulding process synchronously to avoid the test piece directly ejected by air pressure from the mold body falling to the ground and causing the test piece to be damaged.

[0062] 2. The present invention provides downwardly extending limit plates around the demoulding opening, so that when the specimen is demoulded downward in the mold body, the limit plates can vertically guide the demoulded specimen to prevent the demoulded specimen from sliding sideways and falling along the pallet.

[0063] 3. The present invention automatically clamps the test piece stuck in the mold body after preliminary demoulding and completely pulls it out from the mold body. The entire demoulding process does not require manual demoulding, which greatly reduces the labor intensity of workers.

[0064] 4. The present invention drives the second limit block to move from the top of the retreat hole to the bottom of the retreat hole through the telescopic rod. At this time, the third spur gear is just disengaged from the upper rack, and the top block clamps the side of the specimen. Subsequently, as the accommodating plate continues to move downward, the second limit block drives the extension rod to move downward through the bottom rod, and the extension rod gradually compresses the tightening spring downward through the lifting block and drives the top rod to move downward, and the top rod drives the tray to move downward, ensuring that the distance the tray moves downward can always be consistent with the distance the specimen is clamped and brought out, thereby avoiding the subsequent specimen that is clamped and brought out falling onto the tray and causing the specimen to be broken.

[0065] 5. The present invention drives the raised portion to rotate in the opposite direction by a rotating roller, so that the raised portion originally pressed against one side of the slide plate is reset and separated from the slide plate, the reset spring drives the slide plate to reset, and the slide plate drives the top block to separate from the fully demolded specimen, thereby achieving the goal that the top block can automatically separate from the specimen after the specimen is fully demolded, making it convenient for the robot to grip and transfer the fully demolded specimen.

[0066] 6. The present invention uses the first barcode scanner, the second barcode scanner and the third barcode scanner to monitor the specimen information during the specimen production process, ensuring that when the robot clamps the mold body to the demolding machine for demolding, the demolded specimen can be accurately classified according to its purpose. The entire concrete specimen production process can be monitored multiple times to avoid errors in specimen classification. BRIEF DESCRIPTION OF THE DRAWINGS

The air pump injects gas into the mold body 100 through the air pump connection box 3215, the blowing port 3216, and the air hole 101 in sequence, so that the test piece in the mold body 100 moves downward after being subjected to the gas pressure, and the preliminary demolding of the test piece is completed;

[0135] like Figure 8 , Figure 12-13 As shown, during the process in which the specimen in the mold body 100 is pushed downward by the air pressure, the specimen pushes the tray 3225 to move downward and gradually penetrate into the demoulding opening 3213, and the tray 3225 drives the lifting block 3223 to move downward along the guide cavity 32211 through the ejector rod 3224 and gradually compresses the tensioning spring 3222, and the lifting block 3223 drives the bottom rod 32271 to move downward along the second limit block 32273 through the extension rod 3226. During this process, the second limit block 32273 is in a stationary state and the ejector block 32322 does not clamp the portion of the specimen passing through the demoulding opening 3213, thereby achieving synchronous support for the specimen in the initial demoulding process, and preventing the specimen directly ejected by the air pressure from the mold body 100 from falling to the ground, causing the specimen to be damaged;

[0136] like Fig. 9 As shown, the present invention provides downwardly extending limit pieces 3217 around the demoulding opening 3213, so that when the specimen is demoulded downward in the mold body 100, the limit pieces 3217 can vertically guide the demoulded specimen to prevent the demoulded specimen from sliding sideways and falling along the tray 3225, thereby further reducing the risk of the demoulded specimen being damaged.

[0137] After the initial demoulding by the air pressure push method adopted in the prior art, a gap appears between the test piece and the inner wall of the mold, and the air flow blown in by the air pump is discharged along the gap, making it difficult to generate further push force on the test piece. The friction between the remaining part of the test piece and the inner wall of the mold is large, and the test piece is still stuck in the test piece, requiring manual labor to pull the test piece out of the mold, and the pull-out is difficult.

[0138] For this reason, Figure 6-Figure 8 , Fig.14 , Fig.16As shown, after the specimen is initially demoulded, the second cylinder 324 is started, and the second cylinder 324 drives the third spur gear 3238 to move downward through the accommodating plate 3231. Under the meshing action between the third spur gear 3238 and the upper rack 32391, the third spur gear 3238 drives the second spur gear 3237 to rotate through the shaft, and the second spur gear 3237 drives the second bevel gear rod 3235 to rotate through the first spur gear 3236, and the second bevel gear rod 3235 drives the roller 3233 to rotate through the first bevel gear rod 3234, and the roller 3233 rotates the protrusion 32331 to press against one side of the slide plate 32321 and pushes the slide plate 32321 along the guide groove 323 11 moves, the slide plate 32321 gradually compresses the return spring 32325 and pushes the top block 32322 to clamp the two sides of the test piece that passes through the demoulding port 3213, then the third spur gear 3238 separates from the upper rack 32391, and the second cylinder 324 continues to drive the accommodating plate 3231 to move downward until the test piece is completely demoulded from the mold body 100 and the upper end of the test piece is lower than the lower end of the limiting piece 3217, then the second cylinder 324 stops working, so that the test piece stuck in the mold body 100 after the initial demoulding can be automatically clamped and completely pulled out from the mold body 100, and the entire demoulding process does not need to be demoulded manually, which greatly reduces the labor intensity of workers;

[0139] like Figure 8 , Figure 12-13 As shown, in the process of the top block 32322 clamping the test piece after preliminary demoulding and pulling it out from the mold body 100, the accommodating plate 3231 first drives the second limiting block 32273 to move from the top of the retreat hole 322711 to the bottom of the retreat hole 322711 through the telescopic rod 32272. At this time, the third spur gear 3238 is just disengaged from the upper rack 32391, and the top block 32322 clamps the side of the test piece. Subsequently, as the accommodating plate 3231 continues to move downward, The second limit block 32273 drives the extension rod 3226 to move downward through the bottom rod 32271, and the extension rod 3226 gradually compresses the top spring 3222 downward through the lifting block 3223 and drives the top rod 3224 to move downward, and the top rod 3224 drives the tray 3225 to move downward, ensuring that the downward movement distance of the tray 3225 can always be consistent with the descending distance of the clamped specimen, so as to avoid the subsequent clamped specimen falling onto the tray 3225 and causing the specimen to be broken;

[0140] like Fig.15 , Fig.17As shown, when the specimen is completely taken out and the upper end of the specimen is about to be lower than the lower end of the limiting plate 3217, the third spur gear 3238 moves downward to mesh with the lower rack 32392, so that when the third spur gear 3238 continues to move downward, the lower rack 32392 drives the third spur gear 3238 to rotate in the opposite direction, the third spur gear 3238 drives the second spur gear 3237 to rotate in the opposite direction through the shaft, the second spur gear 3237 drives the second bevel gear rod 3235 to rotate in the opposite direction through the first spur gear 3236, and the second bevel gear rod 3235 drives the second bevel gear rod 3235 through the first bevel gear The gear rod 3234 drives the roller 3233 to rotate in the opposite direction, and the roller 3233 drives the protrusion 32331 to rotate in the opposite direction, so that the protrusion 32331 that was originally pressed against one side of the slide plate 32321 is reset and separated from the slide plate 32321. In this process, the reset spring 32325 drives the slide plate 32321 to reset, and the slide plate 32321 drives the top block 32322 to separate from the completely demolded specimen, so that the top block 32322 can automatically separate from the specimen after the specimen is completely demolded, which is convenient for the manipulator 33 to clamp and transfer the completely demolded specimen.

[0141] like Figure 1 As shown, after the demolding of the specimen is completed, the first cylinder 3214 drives the air port 3216 to reset through the air pump connection box 3215, and the manipulator 33 respectively clamps the demolded specimen and the mold body 100 out and places them in the next station, and the second cylinder 324 returns to the initial position.

[0142] Embodiment 2

[0143] like Figure 18-Figure 19 As shown, a method for making a concrete specimen comprises the following steps:

[0144] Step 1, mold on-line process: put the mold body 100 and the tray 3225 on the production line, and raise them from the lifting station 11 to be flush with the pouring and vibrating station 16. Then, the first barcode scanner 12 automatically scans the QR code on the mold body 100, scans the concrete specimen to be poured, and inputs the information of the concrete strength, location, and pouring date of the concrete specimen, so that the QR code information of the mold body 100 is assigned;

[0145] Step 2, concrete loading process: lower the lifting concrete placing machine 13 and pour the concrete from the bucket truck into the hopper of the concrete placing machine 13;

[0146] Step 3, pouring and vibrating process: the concrete placing machine 13 discharges the concrete from the spiral discharge port 14 to the pouring and vibrating station 16 through the shaftless discharging screw arranged at the bottom, and then the mold body 100 after pouring and vibrating is sent to the smoothing station 17 for smoothing, wherein a multifunctional robot 15 for inserting and tamping, inserting and pulling out a spatula, hammering, and smoothing the concrete in the mold body 100 on the smoothing station 17 is arranged above the smoothing station 17;

[0147] Step 4, palletizing process: scan the mold body 100 with the second barcode scanner 24, and according to the content of the read QR code, lift the test piece to different channels according to different uses, and at the same time, write the pouring time of concrete, and palletize on the roller conveyor 22 through the palletizer 21;

[0148] Step 5, resting process: resting the stacked mold body 100;

[0149] Step 6, destacking process: the system automatically calculates the resting time, and after the resting time is met, the stacks are automatically transported from the roller conveyor 22 to the destacking machine 23 for destacking;

[0150] Step 7: Demolding process: The third barcode scanner 31 scans and identifies the QR code of the mold, reads the QR code information, and after confirming the purpose of the test piece, the manipulator 33 grabs and flips it and puts it into the demoulding machine 32, and uses compressed air blowing to demould the test piece from the mold body 100;

[0151] Step 8: Cleaning and spraying process: Use the robot 33 to send the test piece to the coding machine 34 for coding of the QR code and the test piece information. Then, put the test piece into the stacking station 36 for stacking. Send the tray 3225 and the mold body 100 to the cleaning spraying machine 35. After cleaning the concrete residue, spray the demoulding machine 32 and return to the lifting station 11 through the mold return roller line 25 to enter the next cycle.

[0152] The concrete specimen manufacturing method can be generally summarized as a casting unit 1, a rest unit 2 and a demoulding, coding and stacking unit 3.

[0153] It should be noted that: in the process of specimen preparation of the present invention, the specimen preparation is divided into three main parts, namely, the pouring unit 1, the resting unit 2 and the demoulding, coding and stacking unit 3. Before the concrete is poured, vibrated and smoothed in the pouring unit 1, the strength, location and pouring date of the concrete specimen are first given on the surface of the mold body 100 by the first barcode scanning gun 12. Then, when the stacking machine 21 stacks the mold body 100 after pouring and vibrating, the second barcode scanning gun 24 gives the strength, location and pouring date of the concrete specimen on the surface of the mold body 100. The information is identified, so that the stacker 21 can lift the mold body 100 to different channels according to the purpose of different concrete specimens after identifying the information. Finally, in the demoulding process, the third barcode scanning gun 31 will recognize the mold body 100 after resting and destacking again according to the purpose of the specimen, ensuring that when the manipulator 33 clamps the mold body 100 to the demoulding machine 32 for demoulding, the demoulded specimen can be accurately classified according to the purpose. The entire concrete specimen production process can be supervised multiple times to avoid errors in specimen classification;

[0154] In addition, when making a test piece in the present invention, the entire mold body 100 is transported through the robot 33, the mold reflow drum line 25, etc., without the need for manual participation in the handling work, and the process is centralized.

[0155] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
