[0001] The invention relates to the technical field of brewing, in particular to a koji block unloading device on a brewing koji block production line. Background Art

[0002] In the wine making process, one of the important procedures is koji making. The so-called koji making is to mix the raw materials (wheat, barley, peas, etc.) for making koji blocks according to the proportion. After the raw materials are treated with impurities, they are moistened and crushed. The amount of water added to the crushed koji is determined according to the calculated proportion. After the koji and water are mixed evenly, they are stepped on and pressed into koji blocks on the koji making mold. The formed koji blocks need to be moved from the production line, placed on a transport cart and sent to the culture room to enter the culture process. At this point, the automated production line will be transformed into manual operation, which will increase the labor intensity here and cause idle work. The industry urgently needs to develop a device that can complete the pressing and unloading operation of this process with professional mechanical equipment to greatly improve the production and transportation efficiency of koji blocks.

The first conveying frame 1 is provided at the output end of the formed koji blocks, so that the formed koji blocks can be directly put on the first conveying frame, the first conveying frame conveys the koji blocks horizontally, and when conveyed to the end, the koji blocks can be naturally conveyed to the storage trough on the second conveying frame, and then the koji blocks are conveyed in the vertical direction by the second conveying frame, and then delivered to the required place. However, conveyor belts are only suitable for long-distance transportation. No matter where they are transported, the curved blocks must eventually leave the conveyor belts and still need to be removed from the conveyor belts by both hands. This not only increases labor intensity, but also easily causes contamination of the curved blocks.

[0004] Therefore, the industry urgently needs to solve the problem of equipment that can quickly unload and remove the curved material from the conveyor belt after it is pressed. Summary of the invention

[0012] The above-mentioned koji block unloading device used in the wine production line, the pressing surface of the pressing upper mold is a uniformly distributed hemispherical pressing surface or a wavy surface. Beneficial Effects

[0013] Compared with the prior art, the main features of the present invention are as follows: 1. After the pressing part of the curved block of the present invention is pressed, the process switching mechanism directly transfers the curved block together with the mold frame to the unloading process. The two processes are closely connected, the switching consumes less time and the production efficiency is high; 2. In the unloading process, the present invention relies on the unloading device to complete two operations. The first is demoulding, that is, separating the mold frame from the surface of the curved block, and the second is opening the two doors that carry the curved block, so that the curved block automatically falls onto the transport vehicle, completing the operation of unloading the finished product from the production line. This process can be carried out under the control of a predetermined program, and the structural configuration of the present invention is very suitable for docking with this.

[0014] 3. The unloading action of the present invention is divided into two steps. The first step is to open the unloading door latch, and the second step is to use the servo motor to slowly open the two doors that support the curved block. At this time, the curved material will fall slowly and land steadily on the transport vehicle, avoiding damage to the curved block caused by a sudden fall.

[0015] 4. The process switching mechanism of the present invention separates the guiding and driving operations, that is, the side of the nut is used to cooperate with the slide rail to complete the guiding of the nut movement, and the lead screw is used to complete the driving of the nut, and the transposition electromagnet is used to complete the clutch of the mold frame. The three cooperate with each other to make the operation clean and neat, ensuring the smooth progress of the process switching.

[0016] 5. The pressing surface of the curved block of the present invention is an arc surface or a wavy surface, so that the upper surface of the curved block after pressing is a convex arc surface, or a plurality of evenly arranged hemispherical wavy surfaces. The more hemispherical surfaces there are, the more the total area of ​​the upper surface of the curved block can be increased, thereby increasing the area of ​​the curved block in contact with the air during the bacterial cultivation process, thereby improving the bacterial cultivation efficiency.

DETAILED DESCRIPTION

[0020] See also Figure 1 The block unloading device of the present invention is located after the profiling process of the block production line, and its structure includes a unloading platform 1, two discharging doors 2 that open opposite each other, a demolding suction cup 10, a demolding cylinder 12 and a bracket 8, and the block 3 after profiling is contained in the mold frame 9. The unloading platform 1 is installed on the bracket 8, and the bracket can adopt a four-column structure, so that it can be freely operated in the front, back, left and right directions without being affected. A discharging door frame 18 is provided in the middle of the unloading platform 1, and the discharging door 2 is installed in the discharging door frame. The discharging door is rotatably supported on the rotating shaft 6 through the connecting rod 5 and the shaft sleeve 7 on the back side, and the rotating shaft 6 is fixed on the back side of the unloading platform 1. Such a structure can make the two doors fully open without being affected by the rotating shaft. A large gear 14 is fixed on the shaft sleeve 7, and there is a meshing transmission between the large gear and the small gear 15. The small gear is driven to rotate by the servo motor 16, thereby completing the conversion of the closed and open states of the discharging door. The reason why servo motor drive is used is that servo motor has better control characteristics. After being reduced by small gears and large gears, the opening or closing of the discharge door can be safer and smoother, preventing damage to the curved blocks and ensuring the quality requirements of the shape and surface of the curved blocks.

[0021] The process switching mechanism of the present invention is used for switching between processes, that is, it transfers the curved block 3 connected to the mold 9 formed in the pressing process to the unloading process, and transfers it from the pressing conveyor belt 20 to the unloading platform 1.

[0022] The process switching mechanism is provided with two symmetrical sets, which are respectively provided on both sides of the pressing conveyor belt 20 and the unloading platform 1 to ensure that the switching is not blocked. The process switching mechanism is provided with a mold driving motor 25, a lead screw 22 and a nut 21. A transposition electromagnet 23 is provided on the nut. Its function is to play a clutch-like role between the nut and the mold frame 9. When switching, the mold frame is attracted to follow it, and it is released after it is in place, completing the transfer of the position of the mold frame and the curved block. The electromagnetic suction force generated by the transposition electromagnet 23 should be designed to be large enough to ensure that it is sufficient to pull the mold frame 9 to move left and right. The lead screw and the nut form a threaded pair, and the lead screw is driven to rotate by the mold driving motor 25. Two slide rails 24 are parallel and fixed on the frame. It forms a sliding fit with one side of the nut and the slide rail, ensuring that the nut can move freely along the track and smoothly attract the mold frame (9) to move into the unloading process. The process switching mechanism of the present invention separates the functions of guiding, driving and clutching, that is, the side of the nut is used to cooperate with the slide rail to complete the guidance of the nut movement, the lead screw is used to complete the driving of the nut, and the transposition electromagnet is used to complete the clutch of the mold frame. The three cooperate with each other to make the operation clean and neat, ensuring the smooth progress of the process switching.

[0023] Before unloading, the present invention must first separate the mold frame 9 from the curved block 3. For this purpose, the present invention designs a demoulding sucker 10. The demoulding sucker 10 is a square frame structure. Its top cover is connected to the piston rod of the demoulding oil cylinder 12. Its inner frame size is slightly larger than the outer profile of the mold frame 9. The demoulding sucker 10 and the four frames of the square frame structure are respectively provided with electromagnets 11. The mold frame is sucked by the electromagnet. When the demoulding oil cylinder lifts the demoulding sucker 10, the curved block 3 is separated from the mold frame, and is ready for unloading.

[0024] If stickiness occurs during demoulding, slightly vibrate the mold frame to separate smoothly.

[0025] In order to improve the stability of the unloading operation, the present invention adds unloading door latches 4 on the front and rear sides of the unloading door. The unloading door latches are in the form of sheets and are respectively installed at the two ends of the middle part of the two unloading doors. The purpose is to provide support force on the other side of the unloading door 2 and improve the reliability of the unloading door in bearing weight. The other end of the unloading door latch is connected to the piston rod of the unloading cylinder 17. When unloading, the unloading cylinder retracts, driving the unloading door latch 4 to leave the support of the unloading door 2. At this time, if the servo motor of the unloading door is powered and rotated, it will drive the unloading door to rotate slowly and open. The curved block will continue to lower its position as the unloading door descends, and finally land on the transport vehicle 13.

[0026] The surface of the block of the present invention is designed to be uniformly distributed hemispherical pressed surfaces or wavy surfaces. The more hemispherical surfaces there are, the larger the radius is, and the larger the total area of ​​the upper surface of the block is, thereby increasing the area of ​​the block in contact with the air during the bacterial cultivation process and improving the bacterial cultivation efficiency. The hemispherical pressed surface or wavy surface of the block of the present invention is completed in the previous process of the unloading process---the pressing process. The upper mold is made into a hemispherical pressed surface or a wavy surface, so that when the bent material is pressed, a set profile can be pressed out, and then output to the unloading process by a conveyor belt.
