Technical Field

[0001] The invention relates to the technical field of concrete sample detection, and in particular to an automatic sampling and sorting method for concrete samples. Background Art

[0002] Concrete, abbreviated as "concrete", is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement concrete that is mixed with water in a certain proportion using cement as a cementitious material, sand and stone as aggregates. After the finished concrete product is completed, the factory generally needs to make samples of the finished concrete product and then conduct performance tests on the sample blocks of concrete.

[0003] At present, before testing concrete samples, the client needs to manually mark and code the concrete samples before sending them to the testing unit, and the staff of the testing unit are also required to manually collect and classify different types of concrete samples. This highly manual operation-dependent method will cause many inconveniences to both the client and the testing unit, greatly increasing labor costs while reducing subsequent testing efficiency. At the same time, manual operation is also prone to omissions due to negligence in manual operation, and the authenticity and accuracy of subsequent concrete sample test results cannot be guaranteed.

[0004] Therefore, how to reduce the labor cost before testing concrete samples, improve the subsequent testing efficiency, and at the same time improve the authenticity and accuracy of subsequent concrete sample testing results has become a problem that needs to be solved urgently.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Example

[0042] The present invention provides a method for automatically collecting and sorting concrete samples, comprising the following steps:

[0043] S1. Automatic collection of concrete samples: placing a number of concrete samples on an empty tray in the sample collection mechanism 100;

[0044] S2, after confirming the information of the several concrete samples placed on the empty tray in the sample receiving mechanism 100 in step S1 by scanning the order information obtained in the system library, the tray and the several concrete samples placed on it are bound, and the confirmed and bound information is downloaded to the system of the sample receiving mechanism 100;

[0045] S3, implantation of a unique identifier of the concrete sample: the automatic marking and transporting mechanism 200 receives the information of the sample receiving mechanism 100 in step S2, and implants a unique identifier of the concrete sample according to the information;

[0046] S4, secondary confirmation of concrete sample information: in the automatic marking and transportation mechanism 200, the concrete sample with the unique identifier implanted in step S3 is scanned, and the information obtained after the scan is compared and confirmed twice with the order information obtained in the system library in step S2;

[0047] S5, classification of concrete samples: the layered transport mechanism 300 receives the information from the automatic marking transport mechanism 200 in step S4, and layers the concrete samples with different unique identifiers in step S3 according to the information;

[0048] S6. Cache of concrete samples: The sorting and storage mechanism 400 receives the information in the layered transportation mechanism 300 in step S5 and uploads it to the subsequent experimental system. At the same time, the concrete samples that have been layered in step S5 are cached in the sorting and storage mechanisms 400 on the second and third layers.

[0049] S7. Automatic recycling of empty pallets: Recycling and storing empty pallets in the empty pallet storage mechanism 500, and preparing for the empty pallets required in the next step S1.

[0050] In the present invention, the method provided by the present invention can eliminate the need for manual labeling and coding of concrete samples before concrete sample testing, and eliminates the need for manual collection and classification of concrete samples of different categories, thereby bringing convenience to the client and the testing unit, reducing labor costs while improving subsequent testing efficiency; at the same time, the method provided by the present invention can realize automatic sampling and sorting of concrete samples, does not rely on manual operation, and will not cause omissions due to negligence in manual operation, thereby improving the authenticity and accuracy of subsequent concrete sample testing results.

[0051] In this embodiment, refer to Figure 1-13 , the present invention also provides a device for the automatic sampling and sorting method of concrete samples, including a 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, and a support frame 600 for fixing the overall device;

[0052] The sample receiving mechanism 100 includes two sample placing conveyor belts 105 detachably mounted on the support frame 600, and the two sample placing conveyor belts 105 are arranged horizontally and in parallel; two empty tray receiving conveyor belts 104 are arranged between the two sample placing conveyor belts 105, and the two empty tray receiving conveyor belts 104 are arranged horizontally and in parallel, and the entrance of the empty tray receiving conveyor belts 104 is located at the exit of the empty tray storage mechanism 500, and an empty tray receiving lifting cylinder 106 is detachably mounted on the empty tray receiving conveyor belts 104, and the empty tray receiving lifting cylinder 106 is arranged on the empty tray receiving conveyor belts 104. The other end of the lifting cylinder 106 is detachably connected to the support frame 600; two sample delivery conveyor belts 101 are symmetrically arranged at both ends of the sample delivery conveyor belt 105, and the two sample delivery conveyor belts 101 at both ends are respectively arranged horizontally and in parallel, and the bottom end of the sample delivery conveyor belt 101 is detachably installed with a sample delivery lifting cylinder 102, and the end of the sample delivery lifting cylinder 102 is detachably connected to the support frame 600; the exit of the sample delivery conveyor belt 101 is located at the entrance of the automatic marking transport mechanism 200.

[0053] In step S1, the sample conveyor belt 105 will transport the empty pallet to the top of the sample delivery conveyor belt 101 at both ends of the sample conveyor belt 105. When transported to the top of the sample delivery conveyor belt 101, the sample lifting cylinder 102 will drive the sample delivery conveyor belt 101 to lift, so that the sample delivery conveyor belt 101 contacts the bottom of the empty pallet, and at the same time, the empty pallet is also separated from the contact with the sample conveyor belt 105, so as to ensure that the empty pallet will not be separated from the equipment under the continued movement of the sample conveyor belt 105; when the empty pallet is lifted to a certain height, it will stop, and the staff can place a number of concrete samples in the empty pallet on the sample delivery conveyor belt 101 to complete the automatic collection of concrete samples.

[0054] A further optimized solution is that two symmetrically arranged clamps 103 are provided above the two sample conveyor belts 101 at both ends, and the ends of the clamps 103 are detachably mounted with clamp telescopic cylinders, which are detachably connected to the support frame 600; when the empty pallet is lifted to a certain height and stops, the clamps 103 will clamp the two ends of the empty pallet under the extension of the clamp telescopic cylinder, thereby ensuring the stability of the empty pallet when placing the concrete sample in step S1, and preventing the empty pallet from falling.

[0055] The solution is further optimized. In step S1, the number of concrete samples placed on the empty pallet is three. The three concrete samples are placed in a group. This can not only efficiently collect the concrete samples, but also prevent the pallet from being unable to support the concrete samples due to too many concrete samples being placed, thereby ensuring the smooth progress of the work.

[0056] In step S2, the staff will scan the information on the order form obtained from the system library to confirm the information of the three concrete samples placed on the tray on the sample conveyor belt 101; after confirming the concrete sample information, the confirmed concrete sample information will be retrieved and downloaded to the system of the sample receiving mechanism 100 according to the information on the order form, and the three concrete samples placed on the tray will be bound to the tray; after completion, the jaw extension cylinder will contract to make the jaw 103 release the tray, and the sample conveyor belt 101 will move, and the tray on the top of the sample conveyor belt 101 and the concrete samples placed on the tray will be transported to the automatic marking and transportation mechanism 200.

[0057] To further optimize the solution, some concrete samples will be implanted with RFID electronic tags during the production process, while some concrete samples will not be implanted with RFID electronic tags during the production process, but will have identity information handwritten on their surfaces. Therefore, in step S2, the staff can use the RFID tag reader to automatically scan the concrete samples implanted with RFID electronic tags and download the information to the sample receiving agency 100, without having to confirm the information of the concrete samples implanted with RFID electronic tags by scanning the information of the order form obtained in the system library, which greatly saves labor costs.

[0058] To further optimize the solution, in step S2, after confirming the information of the concrete sample, because the pallet already has an RFID electronic tag when it is produced, the staff can use the scanning device external to the device to bind the three concrete samples placed on the pallet on the sample conveyor belt 101 with the pallet on which they are placed, and also download the bound information into the sample receiving mechanism 100; by binding the concrete sample with the pallet on which it is placed, in the later work, the staff can more conveniently check the concrete sample information, thereby improving work efficiency.

[0059] The automatic marking transport mechanism 200 includes two horizontally and parallelly arranged marking conveyor belts 201, which are detachably connected to the support frame 600, and the entrance of the marking conveyor belt 201 is located at the exit of the sample conveying conveyor belt 101, and the exit of the marking conveyor belt 201 is arranged corresponding to the entrance of the layered transport mechanism 300; a marking support platform 202 is arranged on the side of the marking conveyor belt 201 close to the sample conveying conveyor belt 101, and the marking support platform 202 is detachably connected to the support frame 600, and a marking telescopic cylinder 203 is detachably installed on the marking support platform 202, and an inkjet head 204 and a barcode scanner 205 are detachably installed at the end of the marking telescopic cylinder 203 in sequence in a horizontal direction, and the inkjet head 204 is located on the side of the barcode scanner 205 close to the sample conveying conveyor belt 101.

[0060] In step S3, the automatic marking and transporting mechanism 200 will receive all the information in the sample receiving mechanism 100, and the marking conveyor belt 201 will rotate in the same direction as the sample delivering conveyor belt 101, thereby connecting the tray above the sample delivering conveyor belt 101 and the concrete sample above the tray into the automatic marking and transporting mechanism 200; when the three concrete samples pass through the inkjet head 204 in turn, the inkjet head 204 will implant unique identification into the concrete samples in turn according to the information received in the sample receiving mechanism 100.

[0061] According to a further optimization scheme, in step S3, the unique identification implanted by the inkjet head 204 into the concrete sample includes any one or more of a QR code or a barcode, a sample number, an inspection date, a commissioning unit code, a test order number of the sample, a sample production date, and a sample code; in this embodiment, the unique identification implanted by the inkjet head 204 into the concrete sample includes all of the above information, so that complete and sufficient unique identification information can be implanted into the concrete sample, thereby ensuring the integrity and authenticity of the concrete sample information; at the same time, the inkjet head 204 implants sufficient unique identification into the appearance of the concrete sample, which can be more eye-catching. When the concrete sample needs to be manually searched in the later stage, the staff can easily and quickly search for the concrete sample based on the unique identification implanted on the appearance of the concrete sample, thereby greatly reducing labor costs and improving work efficiency.

[0062] In this embodiment, the unique identification of the concrete sample is embedded using a tamper-proof one-time coding technology to ensure the integrity and uniqueness of the concrete sample during transportation and storage. The style of the unique coding identification is as follows:

[0063] The upper part is a QR code or bar code, which can be scanned by a scanner to obtain the concrete sample identity information;

[0064] The middle part is "commissioning unit code - sample test order number - sample production date - sample code", for example, its format is "0-00-0227-xxxxxxxxx";

[0065] The lower part is the sample number and inspection date. For example, the format is: Sample number: 20240001; Inspection date: 240227 (standard maintenance).

[0066] In step S4, after the unique identifier is implanted in the concrete sample, the scanner 205 will scan the unique identifier implanted in the concrete sample in turn, and compare the concrete sample information obtained by scanning with the order information obtained in the system library in step S2 in turn, so as to complete the secondary confirmation of the concrete sample information, which greatly ensures the authenticity and accuracy of the concrete sample information, and also improves the authenticity and accuracy of the subsequent concrete sample test results.

[0067] To further optimize the solution, when the inkjet head 204 and the barcode scanner 205 are implanting unique identification and scanning codes into concrete samples, the marking telescopic cylinder 203 can adjust the positions of the inkjet head 204 and the barcode scanner 205, so as to adapt the spraying position and scanning position of concrete samples of different sizes and shapes, thereby ensuring the smooth progress of the work.

[0068] The layered transport mechanism 300 includes a slide rail 301 detachably mounted on a 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 on the end of the slider, the entrance of the layered conveyor belt 302 is arranged corresponding to the exit of the marking conveyor belt 201, and the exit of the layered conveyor belt 302 is arranged corresponding to the entrance of the second and third layers of the sorting and warehousing mechanism 400, and 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 belt 302.

[0069] In step S5, the layered transport mechanism 300 will receive all the information in the automatic marking transport mechanism 200. When the marking conveyor belt 201 transmits the concrete sample implanted with the unique identification and the second code scanning confirmation to the exit of the marking conveyor belt 201, the layered cylinder 303 will lift the layered conveyor belt 302 to the exit of the marking conveyor belt 201. At the same time, the layered conveyor belt 302 will rotate in the same direction as the marking conveyor belt 201, so as to connect the pallet and the concrete sample on the pallet to the layered conveyor belt 302. After connection, the layered cylinder 303 will layer different types of concrete samples on the layered conveyor belt 302 according to the information received by the layered transport mechanism 300.

[0070] A further optimized solution is that the number of slide rails 301 is two, the two slide rails 301 are arranged in parallel and horizontally, and the two slide rails 301 are detachably connected to the support frame 600; the setting of the two slide rails 301 can further ensure the stability of the layered conveyor belt 302 during the lifting process, and can also ensure the stability of the tray on the layered conveyor belt 302 and the concrete sample on the tray.

[0071] To further optimize the solution, when stratifying the concrete samples, the stratification cylinder 303 will stratify the concrete samples waiting for pressure testing and penetration testing into one layer and the concrete samples waiting for curing into another layer according to the information in the stratification transportation mechanism 300, so as to better classify the concrete samples to be tested and to be cured; because when the concrete samples are produced, due to the different environments they are in, some concrete samples will be in a dry environment for a long time and cause excessive water loss, while concrete samples with too little water are not suitable for testing and need to be cured later before testing. Therefore, classifying the concrete samples to be tested and to be cured can better ensure the smooth progress of subsequent concrete sample testing work, and at the same time will not cause waste of concrete samples, and can also better ensure the authenticity and accuracy of subsequent concrete sample testing results.

[0072] The sorting and storage mechanism 400 is provided with three layers, and each layer includes two first sorting conveyor belts 401 detachably mounted on the support frame 600, the two first sorting conveyor belts 401 are arranged in parallel and horizontally, two third sorting conveyor belts 404 are arranged between the two first sorting conveyor belts 401, and the two third sorting conveyor belts 404 are arranged horizontally and in parallel, the entrances of the third sorting conveyor belts 404 of the second and third layers are arranged correspondingly to the exits of the layered conveyor belts 302, a sorting lifting cylinder 405 is detachably mounted on the support frame 600, and the end of the sorting lifting cylinder 405 is detachably connected to the third sorting conveyor belt 404, and the exit of the third sorting conveyor belt 404 of the bottom layer is located at the entrance of the empty pallet storage mechanism 500.

[0073] In step S6, the sorting and warehousing mechanism 400 will receive all the information in the layered transportation mechanism 300. At the same time, after receiving the information, the sorting and warehousing mechanism 400 will also upload the information to the subsequent experimental system; the sorting lifting cylinder 405 on the second or third layer will drive the third sorting conveyor belt 404 to lift, and lift the third sorting conveyor belt 404 to a height higher than the first sorting conveyor belt 401, and at the same time, the layered conveyor belt 302 will be raised to a height flush with the third sorting conveyor belt 404, and under the same direction rotation of the layered conveyor belt 302 and the third sorting conveyor belt 404, the tray and the concrete samples on the tray are transported to the third sorting conveyor belt 404 on the corresponding layer, that is, the tray waiting to be transported is transported to the third sorting conveyor belt 404 on the corresponding layer. The concrete samples undergoing pressure testing and waiting for penetration testing are transported to the third sorting conveyor belt 404 of any one of the second or third layers, and the concrete samples waiting for curing are transported to the third sorting conveyor belt 404 of another layer of the second or third layers; after the transportation is completed, the third sorting conveyor belt 404 will stop rotating, and the sorting lifting cylinder 405 will descend to make the bottom of the tray contact the first sorting conveyor belt 401. At this time, the first sorting conveyor belt 401 will rotate and transport the tray and the concrete sample on the tray to one side of the third sorting conveyor belt 404, thereby arranging and caching the tray and the concrete sample on the tray horizontally on the first sorting conveyor belt 401, and waiting for the subsequent work of taking away the concrete sample.

[0074] According to a further optimization scheme, the sorting and storage mechanism 400 also includes two second sorting conveyor belts 402 which are arranged horizontally and in parallel, and the second sorting conveyor belts 402 are detachably connected to the support frame 600; the two second sorting conveyor belts 402 are respectively arranged parallel to and corresponding to the two first sorting conveyor belts 401; by setting the second sorting conveyor belts 402, the cache space of the concrete samples can be increased.

[0075] A further optimized solution is that a transition conveyor belt 403 is detachably installed between the first sorting conveyor belt 401 and the second sorting conveyor belt 402, and both ends of the transition conveyor belt 403 are respectively arranged corresponding to the first sorting conveyor belt 401 and the second sorting conveyor belt 402; through the arrangement of the transition conveyor belt 403, when the pallet is transported between the first sorting conveyor belt 401 and the second sorting conveyor belt 402, the transition conveyor belt 403 will rotate in the same direction as the first sorting conveyor belt 401 and the second sorting conveyor belt 402, thereby playing a transition role in the transportation of the pallet, further ensuring the stability of the pallet and the concrete sample above the pallet.

[0076] Further optimization scheme, in step S6, the stratification cylinder 303 will sort the concrete samples to be tested for pressure and penetration to the height flush with the sorting and storage mechanism 400 on the second layer, and then the sorting and storage mechanism 400 on the second layer will connect the concrete samples to be tested for pressure and penetration through the third sorting conveyor 404 and cache them on the first sorting conveyor 401 and the second sorting conveyor 402; similarly, the concrete samples to be cured will be cached on the first sorting conveyor 401 and the second sorting conveyor 402 in the sorting and storage mechanism 400 on the third layer. On the conveyor belt 402; since the concrete samples to be cured have less water content inside, their surface is more easily broken by external collisions, and the concrete samples to be cured are sorted into the third layer, that is, the top layer. When they are taken out by subsequent equipment, there is no sorting and storage mechanism 400 above them, so the possibility of collision of the concrete samples to be cured can be reduced, thereby ensuring the integrity of the concrete samples and avoiding the waste caused by collision and fracture of the concrete samples. At the same time, the authenticity and accuracy of the subsequent concrete sample detection results can be better guaranteed.

[0077] In this embodiment, for subsequent inspection or maintenance work, a robot can be used to clamp and take out the concrete samples cached on the sorting and storage mechanism 400. A scanning device is also provided on the subsequent inspection or maintenance equipment, which can record the identity information of the clamped concrete samples in sequence; when the last concrete sample on a pallet is taken away, the subsequent inspection or maintenance equipment will automatically unbind the pallet from the concrete samples placed above it.

[0078] In this embodiment, in subsequent testing experiments on concrete samples, three concrete samples are generally grouped together for testing, and a set of experimental data is issued after the three concrete samples are tested. This method of combining and packaging concrete samples can significantly improve the experimental efficiency of concrete sample testing. The three concrete samples are combined and packaged and the synchronous transfer and transportation in the testing process reduces the chance of losing a concrete sample or the concrete samples being replaced or falsified during the process, which can further ensure the authenticity of the experimental data. At the same time, there is no need to transport the concrete samples one by one, which improves the transportation efficiency of subsequent experiments.

[0079] The empty pallet storage mechanism 500 includes two horizontal and parallel empty pallet recovery conveyor belts 501, the empty pallet recovery conveyor belts 501 are detachably connected to the support frame 600, the entrance of the empty pallet recovery conveyor belt 501 is located at the exit of the third sorting conveyor belt 404 on the bottom layer, and the exit of the empty pallet recovery conveyor belt 501 is located at the entrance of the empty tray conveyor belt 104; a partition table 502 is arranged above the empty pallet recovery conveyor belt 501, an empty tray through hole is opened on the partition table 502, and a plurality of guide holes are arranged on the upper outer side of the empty tray through hole along the circumferential direction. Toward bar 503, the bottom end of the guide bar 503 is detachably connected to the top of the partition table 502; the top sides of the partition table 502 are detachably installed with a lifting support plate telescopic cylinder 506, and the end of the lifting support plate telescopic cylinder 506 is detachably installed with a lifting support plate 505, and the end of the lifting support plate 505 is fixedly installed with a protrusion; an empty pallet lifting cylinder 504 is arranged between the two empty pallet recovery conveyor belts 501, and the empty pallet lifting cylinder 504 is arranged corresponding to the empty pallet through hole, and the empty pallet lifting cylinder 504 is detachably connected to the support frame 600.

[0080] In step S7, the empty pallet is placed on the empty pallet recovery conveyor belt 501 in the empty pallet storage mechanism 500, and the rotation of the empty pallet recovery conveyor belt 501 will transport the empty pallet; when the empty pallet is transported to the bottom of the empty pallet through hole, the empty pallet lifting cylinder 504 will lift the empty pallet and pass it through the empty pallet through hole to above the partition table 502, and then the lifting support plate telescopic cylinder 506 will extend, driving the lifting support plates 505 on both sides to move, and at this time the protrusions on the lifting support plates 505 will be stuck in the slots on both sides of the bottom of the empty pallet, thereby completing the recovery and storage of the empty pallet between the several guide bars 503.

[0081] In step S7, if it is necessary to recycle and store subsequent empty pallets, when the subsequent empty pallets are transported to the bottom of the empty pallet through-hole, the empty pallet lifting cylinder 504 will lift the subsequent empty pallet, and at the same time, the lifting support plate 505 will retract. However, at this time, the previous empty pallet will not fall due to the retraction of the lifting support plate 505, because the empty pallet lifting cylinder 504 lifts the top of the subsequent empty pallet to contact the bottom of the previous empty pallet. At this time, the previous empty pallet will continue to be lifted together with the subsequent empty pallet under the lifting of the empty pallet lifting cylinder 504, until the bottom of the subsequent empty pallet rises above the partition table 502, the lifting support plate telescopic cylinder 506 will extend, and the protrusion on the lifting support plate 505 will be stuck in the slot at the bottom of the subsequent empty pallet, thereby completing the recycling and storage of the subsequent empty pallets.

[0082] In step S7, when the sample receiving mechanism 100 needs an empty tray, the empty tray lifting cylinder 504 will be lifted until it stops after it touches the bottom of the empty tray between the guide strips 503, and then the lifting support plate 505 will release the limit on the empty tray, and the empty tray lifting cylinder 504 will descend. When it descends to the point where the bottom of the second-to-last empty tray from the bottom is parallel to the lifting support plate 505, the lifting support plate telescopic cylinder 506 will extend and the protrusion on the lifting support plate 505 will be stuck into the slot at the bottom of the second-to-last empty tray. At this time, the empty tray of the first-to-last layer will continue to descend with the empty tray lifting cylinder 504 until it contacts the empty tray recovery conveyor belt 501. After contact, the empty tray recovery conveyor belt 501 will be moved. 01 will rotate and transport the empty pallets of the last layer to the entrance of the empty tray receiving conveyor belt 104. At this time, the empty tray receiving lifting cylinder 106 will lift the empty tray receiving conveyor belt 104 and lift it to the same height as the empty tray recovery conveyor belt 501. Then, under the same direction rotation of the empty tray receiving conveyor belt 104 and the empty tray recovery conveyor belt 501, the empty pallets will be connected into the sample receiving mechanism 100; after connection, the empty tray receiving lifting cylinder 106 will drive the empty tray receiving conveyor belt 104 to descend, so that the bottom of the empty pallet contacts the sample setting conveyor belt 105, and the empty pallet will be transported to the sample delivery conveyor belt 101 under the movement of the sample setting conveyor belt 105, thereby completing the work of preparing the empty pallets required in the next step S1.

[0083] To further optimize the solution, in step S7, after the subsequent equipment takes away the concrete samples in the sorting and storage mechanism 400 on the second and third layers, the subsequent equipment can simultaneously place the empty pallets after taking away the concrete samples onto the empty pallet recovery conveyor belt 501 in the empty pallet storage mechanism 500, and recover and store the empty pallets. There is no need to manually place the empty pallets on the empty pallet recovery conveyor belt 501, thereby reducing labor costs.

[0084] To further optimize the solution, in step S7, if the number of empty pallets that need to be recycled is relatively large, the empty pallets can be placed on the first sorting conveyor belt 401 and the second sorting conveyor belt 402 of the bottom sorting and storage mechanism 400, and arranged and cached; or the bottom sorting lifting cylinder 405 can be made to drive the bottom third sorting conveyor belt 404 to lift, and the empty pallets can be placed on the third sorting conveyor belt 404. After placement, the third sorting conveyor belt 404 will descend, so that the bottom of the empty pallet contacts the first sorting conveyor belt 401, and the first sorting conveyor belt 401 will rotate and arrange and cache the empty pallets, thereby completing the temporary caching of the empty pallets in the bottom sorting and storage mechanism 400.

[0085] When it is necessary to recover and store the empty pallets in the bottom-level sorting and storage mechanism 400 into the empty pallet storage mechanism 500, the first sorting conveyor belt 401 will transport the empty pallets to the top of the third sorting conveyor belt 404. At this time, the sorting lifting cylinder 405 will make the third sorting conveyor belt 404 rise to contact the bottom of the empty pallet, and then the third sorting conveyor belt 404 and the empty pallet recovery conveyor belt 501 will rotate in the same direction to transport the empty pallets to the empty pallet recovery conveyor belt 501, and carry out subsequent recovery and storage work, thereby enabling the empty pallet storage mechanism 500 to complete the recovery and storage of the empty pallets cached in the bottom-level sorting and storage mechanism 400.

[0086] To further optimize the solution, in step S7, the system of the empty pallet storage mechanism 500 will automatically record in real time the number of empty pallets stored in the empty pallet storage mechanism 500, so there is no need to manually count the number of empty pallets stored in the empty pallet storage mechanism 500, thereby reducing labor costs; at the same time, if the empty pallets in the empty pallet storage mechanism 500 are full or cleared, the system can also promptly notify the staff, thereby improving work efficiency.

[0087] Further optimization scheme, in this embodiment, refer to Figure 1 There are four empty pallet storage mechanisms 500, which are arranged in sequence along the transport direction of the empty pallet recovery conveyor belt 501, thereby increasing the storage space of the empty pallets.
