Description

Technical Field

[0001] The utility model relates to the technical field of intelligent sample collection and sorting of concrete specimens, in particular to an intelligent sample collection and sorting device for concrete specimens. Background Technique

[0002] Concrete, simply referred to as "砼", is a general term for engineering composite materials in which cementitious materials bond aggregates into a whole. Usually, the term "concrete" refers to cement concrete obtained by mixing cement as the cementitious material, sand and stone as aggregates, and water in a certain proportion. After the concrete finished product is completed, the factory generally needs to make specimens of the concrete finished product, and then test the performance of the concrete specimen blocks.

[0003] In the inspection and testing industry in the field of construction engineering, the market is huge, there are many testing institutions, and the levels of testing and management are uneven. When it is necessary to test concrete specimens, the client will carry some concrete specimens to the laboratory of the testing unit for testing. After the testing is completed, the construction party will go to the testing unit to pick up the test report. The current testing method requires the client to manually mark and label each specimen and then send it to the testing unit. Subsequently, the staff of the testing unit also need to manually classify, transport, and test the specimens. This highly manual operation method brings a lot of inconvenience to both the client and the testing unit, increases the labor cost, and the efficiency of subsequent testing of concrete specimens is also very low. Relying on manual operation may also result in the loss of specimens or the replacement and forgery of specimens midway, with poor confidentiality and inability to ensure the authenticity and confidentiality of experimental data.

[0004] Therefore, how to reduce the labor cost while improving the efficiency of subsequent performance testing of concrete specimens and effectively guarantee the authenticity and confidentiality of test data has become an urgent problem to be solved. Content of the Utility Model

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Reference Figure 1-13 This utility model provides an intelligent sample collection and sorting device for concrete specimens, comprising:

[0041] The manual layout mechanism 100 is used for manually placing concrete samples to be tested or cured, receiving empty trays, and sending out trays containing concrete samples.

[0042] The automatic marking and transport mechanism 200 is used to mark and scan concrete samples to be tested or cured, and to place the concrete sample trays for entry and marking before delivery. The entrance of the automatic marking and transport mechanism 200 is located at the exit of the manual layout mechanism 100.

[0043] The layered transport mechanism 300 is used for layering concrete sample trays with different types of marking, receiving concrete sample trays with different types of marking, and sending out concrete sample trays with different types of marking; the entrance of the layered transport mechanism 300 is set to correspond to the exit of the automatic marking transport mechanism 200; the layered transport mechanism 300 and the automatic marking transport mechanism 200 are communicatively connected.

[0044] The sorting and storage mechanism 400 has three layers. The second and third layers of the sorting and storage mechanism 400 are used for the layered storage of concrete sample trays with different markings, the entry of concrete sample trays with different markings, and the delivery of concrete sample trays with different markings. The entrances of the second and third layers of the sorting and storage mechanism 400 are respectively set at the exits of the layered transport mechanism 300. The first layer (i.e., the bottom layer) of the sorting and storage mechanism 400 is used for the entry of returned empty trays and the delivery of returned empty trays.

[0045] The empty pallet storage mechanism 500 is used to store empty pallets, receive returned empty pallets, and send out empty pallets. The entrance of the empty pallet storage mechanism 500 is located at the exit of the first layer (i.e., the bottom layer) of the sorting storage mechanism 400, and the exit of the empty pallet storage mechanism 500 is located at the entrance of the manual placement mechanism 100.

[0046] The manual layout mechanism 100, the automatic marking and transport mechanism 200, the layered transport mechanism 300, the sorting and storage mechanism 400, and the empty pallet storage mechanism 500 are all detachably equipped with support frames 600 on their outer sides.

[0047] In this invention, the automatic intelligent collection and sorting of concrete samples can be achieved by setting up a manual sampling mechanism 100, an automatic marking and transportation mechanism 200, a layered transportation mechanism 300, a sorting and storage mechanism 400, and an empty pallet storage mechanism 500. This improves the efficiency of concrete sample collection and sorting, greatly reduces labor costs, and also improves the efficiency of subsequent concrete sample performance testing. At the same time, the automated collection and sorting of concrete samples does not rely on manual operation, which improves confidentiality and avoids the loss of samples or the substitution or falsification of samples during the process, thus improving the authenticity of experimental data.

[0048] In a further optimized design, the manual layout mechanism 100 includes two layout conveyor belts 105 that are detachably mounted on the support frame 600. The two layout conveyor belts 105 are arranged horizontally and parallel to each other, and the layout conveyor belts 105 are used to transport empty pallets within the manual layout mechanism 100.

[0049] In this embodiment, three concrete samples can be placed on an empty pallet. The detachable connection between the layout conveyor belt 105 and the support frame 600 can be a bolt connection. The empty pallets on the layout conveyor belt 105 come from the empty pallet storage mechanism 500.

[0050] Two empty pallet receiving conveyor belts 104 are arranged between the two layout conveyor belts 105. The two empty pallet receiving conveyor belts 104 are arranged horizontally and parallel to each other. The entrance of the empty pallet receiving conveyor belt 104 is located at the exit of the empty pallet storage mechanism 500. The empty pallet receiving conveyor belt 104 is used for receiving empty pallets. An empty pallet lifting cylinder 106 is detachably installed on the empty pallet receiving conveyor belt 104. The other end of the empty pallet lifting cylinder 106 is detachably connected to the support frame 600. Two sample delivery conveyor belts 101 are arranged at one end of the layout conveyor belt 105. The two sample delivery conveyor belts 101 are arranged horizontally and parallel to each other. A layout lifting cylinder 102 is detachably installed on the sample delivery conveyor belt 101. The end of the layout lifting cylinder 102 is detachably connected to the support frame 600. The sample delivery conveyor belt 101 is used for manually placing concrete samples to be tested or cured and for sending out sample pallets. The exit of the sample delivery conveyor belt 101 is located at the entrance of the automatic marking and transport mechanism 200.

[0051] In operation, the empty pallet lifting cylinder 106 rises, causing the empty pallet conveyor belt 104 to rise as well. This raises the height of the empty pallet conveyor belt 104 above the height of the lofting conveyor belt 105, preventing the horizontal movement of the lofting conveyor belt 105 from affecting the empty pallet receiving conveyor belt 104's access to empty pallets. Empty pallets within the empty pallet storage mechanism 500 will enter above the lofting conveyor belt 105 under the movement of the empty pallet conveyor belt 104. When the empty pallet is fully inside, the empty pallet conveyor belt 104 stops moving, and the empty pallet lifting cylinder 106 descends, causing the empty pallet to contact the lofting conveyor belt 105. The empty pallet will then be lofted... Driven by the conveyor belt 105, the sample delivery conveyor belt 101 moves above the sample delivery conveyor belt 101. At this time, the sample delivery conveyor belt 105 stops moving, and the sample delivery lifting cylinder 102 drives the sample delivery conveyor belt 101 to rise, thereby driving the empty pallet to rise. At this time, the operator manually places three concrete samples as a group on the empty pallet on the sample delivery conveyor belt 101 according to the order form displayed on the external operation display screen of this equipment. The operator also confirms the concrete sample information in the order form list on the external touch screen of this equipment. After confirmation, the pallet loaded with concrete samples will enter the automatic marking and transport mechanism 200 under the movement of the sample delivery conveyor belt 101.

[0052] In this embodiment, two sample delivery conveyor belts 101 and two sample lifting cylinders 102 are provided at both ends of the layout conveyor belt 105. There are also two automatic marking and transport mechanisms 200, which are respectively connected to the two sample delivery conveyor belts 101 at both ends of the layout conveyor belt 105. When placing concrete samples on one of the sample delivery conveyor belts 101, the empty tray conveyor belt 104 will simultaneously connect to the empty tray. At this time, the layout conveyor belt 105 will move in the opposite direction and transport the empty tray to the sample delivery conveyor belt 101 at the other end. The operator can simultaneously place concrete samples on the empty tray on the sample delivery conveyor belt 101 at the other end, which increases the efficiency of concrete sample collection.

[0053] To further optimize the design, a gripper mounting plate is installed above the sample conveyor belt 101. The gripper mounting plate is detachably connected to the support frame 600. Two gripper telescopic cylinders are detachably installed on the gripper mounting plate. Grippers 103 are detachably installed at the ends of the gripper telescopic cylinders. The two sample conveyor belts 101 and the two grippers 103 are set in a one-to-one correspondence.

[0054] When the layout lifting cylinder 102 lifts the empty pallet, the empty pallet is prone to instability because it is no longer in contact with the layout conveyor belt 105. However, the clamps 103 are designed so that when the empty pallet is lifted, the extension of the clamp telescopic cylinder will clamp the two clamps 103 on both sides of the empty pallet, greatly ensuring the stability of the empty pallet. When the concrete sample is placed manually, the empty pallet is less likely to fall, ensuring the smooth progress of the work and improving work efficiency. At the same time, the concrete sample will not fall with the empty pallet, thus avoiding the concrete sample from being broken. After the concrete sample is placed, the clamp telescopic cylinder can be controlled to retract, at which point the clamps 103 disengage from the pallet, allowing the pallet with the concrete sample to smoothly enter the automatic marking and transport mechanism 200.

[0055] In this embodiment, each end of the gripper 103 is provided with a protrusion, and the two protrusions are adapted to the slots at the bottom of the empty tray. When the gripper 103 fixes the empty tray, the protrusions on the gripper 103 will be inserted into the slots at the bottom of the empty tray, thereby better fixing the empty tray and better ensuring the stability of the empty tray when the concrete sample is placed manually.

[0056] Further optimizing the design, the automatic marking and transport mechanism 200 includes two horizontally and parallelly arranged marking conveyor belts 201. The marking conveyor belts 201 are detachably connected to the support frame 600. The entrance of the marking conveyor belt 201 is located at the exit of the sample delivery conveyor belt 101, and the exit of the marking conveyor belt 201 corresponds to the entrance of the layered transport mechanism 300. The marking conveyor belts 201 are used for receiving sample trays and sending marked sample trays out. A marking support platform is provided on the side of the marking conveyor belt 201 near the sample delivery conveyor belt 101. 202. The marking support platform 202 is detachably connected to the support frame 600. A marking telescopic cylinder 203 is detachably installed on the marking support platform 202. An inkjet head 204 and a barcode scanner 205 are detachably installed at the end of the marking telescopic cylinder 203 in the horizontal direction. The inkjet head 204 is located on the side of the barcode scanner 205 that is close to the sample conveyor belt 101. The inkjet head 204 and the barcode scanner 205 are used for marking and scanning the concrete samples to be tested or cured, respectively. The barcode scanner 205 is communicatively connected to the layered transport mechanism 300.

[0057] In this embodiment, the inkjet head 204 can be a thermal inkjet head, and the barcode scanner 205 can be a QR code reader.

[0058] When concrete samples are produced, some are equipped with RFID tags, while others are not. Therefore, when concrete samples are manually placed on empty pallets on the sample delivery conveyor belt 101, the concrete samples with RFID tags on the three samples on the empty pallet are scanned beforehand, and the scanned information is uploaded to the system database. For concrete samples without RFID tags, after placement, the staff will manually input and upload the information to the system database according to the information on the order form. After completion, the three concrete samples are bound together, and the information is uploaded to the system database.

[0059] After the previous step is completed, the rotation of the marking conveyor belt 201 and the co-rotation of the sample delivery conveyor belt 101 will bring the tray containing the concrete sample onto the marking conveyor belt 201. When the concrete sample passes the inkjet head 204, the inkjet head 204 will sequentially spray the information obtained by scanning the RFID electronic tag in the system library and the information manually entered according to the order form onto the appearance of the concrete sample. The concrete sample with the information sprayed will be conveyed to the barcode scanner 205. The barcode scanner 205 will identify the information sprayed on the concrete sample a second time and upload the scanned information to the system library for comparison and confirmation, thereby further ensuring the accuracy of the concrete sample information. At the same time, the barcode scanner 205 will also send the scanned concrete sample information to the layered transport mechanism 300 for the next layering work. After the concrete sample is sprayed and scanned, it will be driven by the marking conveyor belt 201 into the layered transport mechanism 300 for layering processing.

[0060] The marking telescopic cylinder 203 automatically adjusts according to the different shapes and sizes of concrete samples, thereby adjusting the position of the inkjet head 204 and the barcode scanner 205 to ensure the smooth progress of the spraying and scanning work.

[0061] Furthermore, the operation of the inkjet head 204 spraying information on the appearance of concrete samples allows staff to quickly identify abnormal concrete samples when the entire system malfunctions. This reduces the cost of manually searching for abnormal concrete samples and further improves work efficiency.

[0062] Further optimizing the scheme, the layered transport mechanism 300 includes a slide rail 301 detachably mounted on the support frame 600. A slider is slidably mounted on the upper limit of the slide rail 301. Two parallel and horizontally arranged layered conveyor belts 302 are detachably mounted at the ends of the sliders. The entrance of the layered conveyor belts 302 corresponds to the exit of the marking conveyor belt 201, and the exit of the layered conveyor belts 302 corresponds to the entrances of the second and third layers of the sorting and storage mechanism 400. The layered conveyor belts 302 are used for the access of marked sample trays and the delivery of different types of marked sample trays. A layered cylinder 303 is detachably mounted on the support frame 600. The layered cylinder 303 is arranged parallel to the slide rail 301, and the end of the layered cylinder 303 is detachably connected to the layered conveyor belts 302. The layered cylinder 303 is used to layer the trays of different types of marked samples. The layered cylinder 303 is communicatively connected to the barcode scanner 205.

[0063] In this embodiment, there are two slide rails 301, and the two slide rails 301 are set horizontally in parallel. The setting of two slide rails 301, compared with setting only one slide rail 301, makes the lifting and lowering of the layered conveyor belt 302 more stable, further avoiding the situation where the concrete sample falls during the lifting and lowering process, and increasing work efficiency.

[0064] When the marking conveyor belt 201 transports the concrete sample on the pallet to the entrance of the layering conveyor belt 302, the layering cylinder 303 will promptly raise and lower the layering conveyor belt 302 to the same height as the marking conveyor belt 201. The co-rotation of the layering conveyor belt 302 and the marking conveyor belt 201 will transport the concrete sample onto the layering conveyor belt 302. At this time, the layering cylinder 303 will automatically layer the three concrete samples on the layering conveyor belt 302 according to the data transmitted by the barcode scanner 205.

[0065] In this embodiment, the compressive concrete sample to be tested is sorted to the second layer of the sorting and storage mechanism 400, and the concrete sample to be cured is sorted to the third layer of the sorting and storage mechanism 400. After the layers are sorted, the pallet and the concrete sample on it are transported to different layers in the sorting and storage mechanism 400 by the rotation of the layering conveyor belt 302, thereby completing the layering of the compressive concrete sample.

[0066] In a further optimized design, each layer of the sorting and storage mechanism 400 includes two first sorting conveyor belts 401 detachably mounted on the support frame 600. The two first sorting conveyor belts 401 are parallel and horizontally arranged. The first sorting conveyor belts 401 of the second and third layers are used to store trays of different types of marked samples. Two third sorting conveyor belts 404 are arranged between the two first sorting conveyor belts 401, and these two third sorting conveyor belts 404 are horizontal and parallel. The entrances of the third sorting conveyor belts 404 of the second and third layers are connected to the layered conveyor belts 302. At the outlet, a sorting lifting cylinder 405 is detachably installed on the support frame 600. The end of the sorting lifting cylinder 405 is detachably connected to the third sorting conveyor belt 404. The third sorting conveyor belts 404 of the second and third layers are used for the access of different types of marked sample trays and the delivery of layered sample trays. The outlet of the third sorting conveyor belt 404 of the first layer (i.e., the bottom layer) is located at the entrance of the empty pallet storage mechanism 500. The third sorting conveyor belt 404 of the first layer (i.e., the bottom layer) is used for the access of returning empty pallets and the delivery of returning empty pallets.

[0067] While the layered conveyor belt 302 is conveying the concrete sample, the third sorting conveyor belt 404 in the sorting and storage mechanism 400, which corresponds to the second and third layers of the concrete sample, will be raised to a height exceeding that of the first sorting conveyor belt 401 under the lifting of the sorting lifting cylinder 405, and will be level with the layered conveyor belt 302 at this time. At this time, the concrete sample will enter the upper part of the third sorting conveyor belt 404 under the same rotation of the layered conveyor belt 302 and the third sorting conveyor belt 404.

[0068] If it is necessary to immediately transport the layered concrete samples to the outside, the concrete samples that have entered the third sorting conveyor belt 404 will continue to be transported to the outside under the movement of the third sorting conveyor belt 404.

[0069] If it is necessary to buffer the layered concrete samples, when the concrete samples enter the third sorting conveyor belt 404, the third sorting conveyor belt 404 will stop moving, and the sorting lifting cylinder 405 will also descend, so that the bottom of the tray contacts the first sorting conveyor belt 401. At this time, the first sorting conveyor belt 401 will rotate and transport the concrete samples to the side of the third sorting conveyor belt 404. At this time, the first sorting conveyor belt 401 will stop rotating, and the third sorting conveyor belt 404 and the sorting lifting cylinder 405 will repeat the above operation to receive the next group of concrete samples. In this way, the concrete samples are buffered on the first sorting conveyor belt 401 and wait for the subsequent removal and unbinding of the layered concrete samples.

[0070] When empty pallets need to be recycled into the equipment, they are delivered manually or by machine to the sorting and storage mechanism 400 on the first floor. At this time, the third sorting conveyor belt 404 on the first floor will rise and rotate, thus smoothly receiving the empty pallets, and can continue to rotate to transport the empty pallets into the empty pallet storage mechanism 500.

[0071] If it is necessary to buffer empty pallets after use, the third sorting conveyor belt 404 on the first layer will stop rotating and descend after successfully receiving an empty pallet, so that the bottom of the empty pallet contacts the first sorting conveyor belt 401 on the first layer. The rotation of the first sorting conveyor belt 401 will transport the empty pallet to the side of the third sorting conveyor belt 404. By repeating the above operation, the empty pallets can be arranged and buffered on the first sorting conveyor belt 401.

[0072] In a further optimized design, the sorting and storage mechanism 400 also includes two horizontally and parallelly arranged second sorting conveyor belts 402, which are detachably connected to the support frame 600; the two second sorting conveyor belts 402 are respectively parallel to and corresponding to the two first sorting conveyor belts 401.

[0073] By adding a second sorting conveyor belt 402, the storage space of the sorting and storage mechanism 400 can be expanded, thereby improving work efficiency.

[0074] In a further optimized design, a transition conveyor belt 403 is detachably installed between the first sorting conveyor belt 401 and the second sorting conveyor belt 402, with the two ends of the transition conveyor belt 403 corresponding to the first sorting conveyor belt 401 and the second sorting conveyor belt 402, respectively.

[0075] By adding a transition conveyor belt 403 between the first sorting conveyor belt 401 and the second sorting conveyor belt 402, the transport of pallets between the first sorting conveyor belt 401 and the second sorting conveyor belt 402 can be made smoother, further preventing concrete samples from falling off.

[0076] In a further optimized design, roller lifting cylinders 406 are detachably installed on the outer sides of both first sorting conveyor belts 401. A transition roller 407 is rotatably installed at the end of the roller lifting cylinder 406. The transition roller 407 is arranged parallel to the first sorting conveyor belt 401. Two transition frames 408 are symmetrically arranged at both ends of the transition roller 407. The transition frames 408 are detachably connected to the first sorting conveyor belt 401.

[0077] When a pallet is received by the third sorting conveyor belt 404, the transition roller 407 near the entrance of the third sorting conveyor belt 404 will be raised to the same height as the third sorting conveyor belt 404 by the roller lifting cylinder 406. Under the combined action of the transition roller 407 and the transition frame 408, the pallet can be smoothly received. At the same time, the transition roller 407 on the other side will be raised to the middle of the receiving pallet, which will block the receiving pallet and prevent the pallet from sliding off the third sorting conveyor belt 404 from the other end due to inertia, thus further avoiding the concrete sample and the pallet from falling.

[0078] Further optimizing the design, the empty pallet storage mechanism 500 includes two horizontally and parallelly arranged empty pallet recycling conveyor belts 501. The empty pallet recycling conveyor belts 501 are detachably connected to the support frame 600. The entrance of the empty pallet recycling conveyor belts 501 is located at the exit of the third sorting conveyor belt 404 on the first layer (i.e., the bottom layer), and the exit of the empty pallet recycling conveyor belts 501 is located at the entrance of the empty pallet receiving conveyor belt 104. The empty pallet recycling conveyor belts 501 are used for receiving and sending out empty pallets. A partition platform 502 is provided above the conveyor belt 501. The partition platform 502 has through holes for empty pallets. Several guide strips 503 are arranged circumferentially above and outside the through holes. The bottom ends of the guide strips 503 are detachably connected to the top end of the partition platform 502. A lifting support plate telescopic cylinder 506 is detachably installed at the top end of the partition platform 502. A lifting support plate 505 is detachably installed at the end of the lifting support plate telescopic cylinder 506. A protrusion is fixedly installed at the end of the lifting support plate 505 to support the empty pallets. An empty pallet lifting cylinder 504 is provided between the two empty pallet recycling conveyor belts 501. The empty pallet lifting cylinder 504 is correspondingly positioned to the through holes for empty pallets and is detachably connected to the support frame 600. Empty pallets are stored between the guide strips 503.

[0079] In this embodiment, there are four empty pallet storage mechanisms 500, which are arranged sequentially along the movement direction of the empty pallet recycling conveyor belt 501, thereby increasing the storage space for empty pallets.

[0080] In this embodiment, the protrusions are adapted to the slots on both sides of the bottom of the tray, and the number of protrusions at the end of the lifting support plate 505 is also two, which are respectively set to correspond to the two slots at the bottom of the empty tray.

[0081] In this embodiment, there are 6 guide strips 503, which are evenly arranged around the outer circumference of the through hole of the empty disk.

[0082] When the third sorting conveyor belt 404 of the first layer transports an empty pallet into the empty pallet storage mechanism 500, the empty pallet recycling conveyor belt 501 rotates in the same direction as the third sorting conveyor belt 404 of the first layer to receive the empty pallet. When the empty pallet is transported on the empty pallet recycling conveyor belt 501 to the area directly below the empty pallet through hole of the separator 502, the empty pallet lifting cylinder 504 will lift it upwards and raise the empty pallet above the separator 502. At this time, the lifting support plate telescopic cylinder 506 will drive the lifting support plate 505 to move and engage the protrusion into the slot at the bottom of the pallet. At this time, the empty pallet lifting cylinder 504 will retract, and the pallet will not fall due to the support of the lifting support plate 505. If the next empty pallet enters, the above operation is repeated to store the empty pallet between the guide bars 503.

[0083] When it is necessary to remove an empty pallet from the empty pallet storage mechanism 500, the empty pallet lifting cylinder 504 will first press against the empty pallets between the guide bars 503 and descend to a position where the second-to-last layer of empty pallets is flush with the bottom of the lifting support plate 505. The lifting support plate 505 will then hold the second-to-last layer of empty pallets in place. At this time, the empty pallet lifting cylinder 504 will retract, and the last layer of empty pallets will come into contact with the empty pallet recycling conveyor belt 501. The empty pallets will then be transported to the empty pallet receiving conveyor belt 104 by the movement of the empty pallet recycling conveyor belt 501, thereby completing the removal of the empty pallets.
