Description

Technical Field

[0002] In the brewing of liquor, the mash needs to be piled up after cooling to achieve aerobic fermentation. The traditional process is manual operation, in which the mash is piled up in layers and spread in bulk on the ground from the inside out, and finally a hemispherical pile is achieved.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0040] like Figure 1-Figure 8 The system for automatically piling up fermented grains for brewing liquor shown in the figure comprises: a walking mechanism 1, a grain buffering and receiving mechanism 2, a quantitative conveying mechanism 3, a piling mechanism 4 and a visual positioning mechanism 5.

[0041] like Figure 1-Figure 4 As shown, the traveling mechanism 1 includes a frame 11, a track 12, a roller 13 and a driving member, the track 12 is laid on the ground, the bottom of the frame 11 is provided with a roller 13 that can travel along the track 12, and the frame 11 is provided with a driving member, which is connected to the roller 13. Therefore, the driving member can realize the entire frame 11 traveling along the track 12 by driving the roller 13 to rotate, so as to facilitate moving to different positions for stacking.

[0042] In a specific configuration, the frame 11 is a U-shaped frame with an opening downward, and a walking mechanism 1 is provided at the bottom of the left and right sides of the U-shaped frame. Figure 3 and Figure 4 As shown, the driving member includes a first motor 14 and a first transmission mechanism 15. The first motor 14 is connected to the roller 13 through the first transmission mechanism 15. The first transmission mechanism 15 can select common belt drive, chain drive and other transmission mechanisms. This is a common transmission method in the field and will not be repeated.

[0043] like Figure 1 , Figure 5 and Figure 6 As shown, the slag receiving mechanism 2 includes a temporary storage bucket 21 and a first conveyor 22. The temporary storage bucket 21 is fixed on the frame 11. The top of the temporary storage bucket 21 is open to form a feeding port. A first discharge port is provided on one side of the temporary storage bucket 21. The bottom of the temporary storage bucket 21 is provided with a first conveyor 22 for transporting slag to the first discharge port.

[0044] The quantitative conveying mechanism 3 includes a feeding hopper 31, a second conveyor 32, a guide hopper 33 and a scraper. The feeding hopper 31 is fixed at the first discharge port, and a second discharge port is provided on one side of the feeding hopper 31. A second conveyor 32 for transporting mash to the second discharge port is provided at the bottom of the feeding hopper 31. A guide hopper 33 and a scraper are provided at the second discharge port. The scraper is located on the upstream side of the guide hopper 33, and the scraper is used to break up the mash.

[0045] In this system, the temporary storage bucket 21 in the slag buffer receiving mechanism 2 is used to receive and temporarily store the slag after cooling, and then the slag is transported to the feeding hopper 31 through the first conveyor 22, and then the slag is transported to the guide hopper 33 through the second conveyor 32 to feed the stacking machine robot 41. During the feeding, the scraper can break up the slag to prevent uneven slag or large lumps.

[0046] In the specific setting, a buffer connection mechanism 2 and a quantitative conveying mechanism 3 are provided on the left side of the U-shaped frame. Both the first conveyor 22 and the second conveyor 32 can be belt conveyors. This type of belt conveyor uses belts or chain plates to transport materials. It is widely used in the transportation of bulk materials and is a conventional conveying method in this field, which will not be described in detail.

[0047] like Figure 5 and Figure 6 As shown, the scraper includes a second motor, a driving sprocket, a driven sprocket, a chain 35 and a scraper 34. From bottom to top, a bracket inclined toward the feeding hopper 31 is provided on the upper side of the guide hopper 33. A driving sprocket and a driven sprocket are provided on the bracket. The second motor is connected to the driving sprocket. An annular chain 35 is provided between the driving sprocket and the driven sprocket. A scraper 34 is fixed on the chain 35. There are multiple scrapers 34 and they are arranged at intervals along the circumference of the chain 35. The outer edge of each scraper 34 away from the chain 35 is provided with serrations.

[0048] Therefore, when the second motor drives the chain 35 to rotate in a circular motion through the driving sprocket and the driven sprocket, the scraper 34 can be driven to scrape the mash from the belt of the second conveyor 32 into the guide hopper 33. In addition, the outer edge of the scraper 34 away from the chain 35 is provided with saw teeth, which can actively break up the mash while scraping.

[0049] like Figure 1 , Figure 7 and Figure 8 As shown, the stacking mechanism 4 includes a robot 41 and a material spreading hopper 42. The robot 41 is a multi-degree-of-freedom robot 41. The robot 41 is arranged on the frame 11. The movable end of the robot 41 is provided with a material spreading hopper 42. The top of the material spreading hopper 42 is provided with a material receiving port. A third material discharge port is provided on one side of the material spreading hopper 42. A third conveyor 43 for transporting mash to the third material discharge port is provided in the material spreading hopper 42. The visual positioning mechanism 5 includes a plurality of cameras 51. The cameras 51 are arranged on the frame 11.

[0050] In this system, the robot 41 is used to move the material hopper 42 to the guide hopper 33 to receive the material, and then adjust the position of the material hopper 42 to pile the material. The robot 41 is a multi-degree-of-freedom robot 41, which can flexibly adjust the spatial position of the material hopper 42 to meet the pile requirements. The material hopper 42 is provided with a third conveyor 43, which can automatically transport the mash to the third discharge port for discharge.

[0051] The visual positioning mechanism 5 is used to detect the shape of the simulated pile through the camera 51 when the robot 41 is piling. On the one hand, the size of the pile is detected in real time, and the height position of the robot 41 laying the materials layer by layer is adjusted; on the other hand, the robot 41 is guided to pile up the material in a crown shape close to the surface of the pile, and the path of the robot 41 is planned in real time, so that the final shape of the pile is as follows: Figure 1 and Figure 2 Therefore, the visual positioning mechanism 5 mainly obtains image information through the camera 51, thereby providing navigation and positioning for the action of the robot 41. There are many related visual positioning implementation schemes in the prior art, and those skilled in the art can adjust and select them according to needs.

[0052] In a specific configuration, a stacking mechanism 4 and a camera 51 are provided on the top of the U-shaped frame. The robot 41 in the stacking mechanism 4 is a six-axis robot 41 and is mounted on the frame 11 in an inverted manner.

[0053] The six-axis machine has six degrees of freedom, including rotation (S axis), lower arm (L axis), upper arm (U axis), wrist rotation (R axis), wrist swing (B axis) and wrist rotation (T axis); the six joints are combined to realize the six-degree-of-freedom movement of the end. The combination of these axes enables the six-axis robot 41 to achieve almost any trajectory or angle in space, with high flexibility and adaptability. In addition, the six-axis robot 41 is highly programmable and can perform various tasks by writing and modifying programs. Therefore, in conjunction with the above-mentioned visual positioning mechanism 5, the position of the paving hopper 42 can be flexibly adjusted to achieve the effect of restoring traditional manual piling.

[0054] like Figure 7 and Figure 8 As shown, the third conveyor 43 is a belt conveyor, and the discharge speed can be adjusted by adjusting the speed of the belt conveyor.

[0055] The third discharge port is provided with a first comb plate 44 and a roller comb 45. The first comb plate 44 is fixedly connected to the material spreading hopper 42. The first comb plate 44 is provided with a plurality of evenly arranged first strip holes. The roller comb 45 is rotationally connected to the material spreading hopper 42. The roller comb 45 is located on the downstream side of the comb plate and is adjacent to the first comb plate 44. The roller comb 45 is provided with a plurality of comb teeth corresponding to the first strip holes one by one. The material spreading hopper 42 is provided with a third motor, which is connected to the roller comb 45. Therefore, when the third motor drives the roller comb 45 to rotate, the roller comb 45 cooperates with the first comb plate 44 to further break up the discharged mash, prevent uneven mash or large lumps, and send out the mash at the same time. Moreover, by controlling the rotation speed of the roller comb 45, the material can be evenly discharged and lightly sprinkled on the surface of the pile when spreading the material.

[0056] Furthermore, if Figure 8As shown, a second combing plate 46 is further provided at the third discharge port, and the upper edge of the second combing plate 46 is adjacent to the belt end of the third conveyor 43 close to the third discharge port, so that the upper part of the second combing plate 46 can play a role similar to that of the scraper 34, and can scrape off the residual mash on the belt of the third conveyor 43. At the same time, a plurality of evenly arranged second strip holes are provided on the second combing plate 46, and the arrangement spacing of the second strip holes is smaller than the arrangement spacing of the first strip holes, so that the second combing plate 46 can be used to scrape and comb the surface of the pile more delicately later to achieve more uniform loose spreading.

[0057] The working process of this system in practical application is as follows:

[0058] 1. Temporary storage of fermented grains

[0059] After the cooling is completed, the mash is transferred to the temporary storage hopper 21, the volume of which is ≥ 2m 3 , a steamer of materials can be temporarily stored. When starting to pile up, the temporary storage bucket 21 quantitatively supplies materials to the pile-up robot 41, and the scraper breaks up the mash during feeding to prevent uneven mash or large lumps.

[0060] 2. Robot 41 receives materials

[0061] When starting to pile up, the robot 41 moves the spreading hopper 42 to the material receiving point, and the temporary storage bucket 21 supplies material to the robot 41 in a quantitative manner, with each supply of about 60L (adjustable). After the material receiving is completed, the robot 41 starts to spread the material and pile up.

[0062] 3. Robot 41 stacking

[0063] The main body of the stacking robot 41 adopts an inverted six-axis robot 41. When stacking, the robot 41 drives the spreading hopper 42 to spread a small pile on the ground at the stacking point, and then the robot 41 drives the spreading hopper 42 to spread the material layer by layer from the inside to the outside close to the surface of the pile, and two combing plates and a roller comb 45 are arranged at the outlet position of the spreading hopper 42 to ensure that the mash is loose and free of lumps when stacking and spreading the material.

[0064] When piling, on the one hand, the material is spread layer by layer from the inside to the outside to increase the dissolved oxygen content of the material in the pile and ensure the stacking effect; on the other hand, the material is spread close to the surface of the pile to prevent the pile from being compacted when piling; at the same time, the fermented grains are broken up when piling to prevent lumps or uneven fermented grains from affecting the stacking and fermentation effect. The robot 41 drives the spreading hopper 42 to circulate the material to pile until the whole pile is completed.

[0065] 4. Camera 51 detection

[0066] When piling, the camera 51 detects the shape of the simulated pile. On the one hand, it detects the size of the pile in real time and adjusts the height position of the robot 41 for laying materials layer by layer; on the other hand, it guides the robot 41 to pile up in a crown shape close to the surface of the pile and plans the path of the robot 41 in real time so that the final shape of the pile is hemispherical.

[0067] 5. Complete the stacking

[0068] After the pile is completed, the robot 41 retracts its joints and returns to the starting position, with the entire inverted robot 41 above the pile to ensure that it does not touch the pile when the pile robot 41 moves to the next pile point. The entire pile process follows tradition, with the robot 41 completely simulating the process of manually spreading the pile layer by layer to complete the pile.

[0069] In summary, this solution realizes automation to simulate manual heaping on the basis of following traditional processes, thereby reducing the number of operators through automated operations, reducing the intensity of manual labor, and standardizing production. This solution uses the robot 41 to simulate manual operation, and the camera 51 replaces the human eye to heap according to the hemisphere, retaining the traditional ground stacking, and when heaping, the heap is piled from the inside to the outside in layers, and is lightly spread and evenly spread close to the surface of the heap, effectively ensuring the effect of the stacking of the mash.

[0070] Although a portion of the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations to these embodiments are within the scope of protection of the claims of the present invention without departing from the principles and purpose of the present invention.
