Description

Technical Field

[0001] The invention relates to the technical field of koji fermentation, in particular to a fully automatic koji turning device for koji fermentation. Background Art

[0002] During the fermentation process, koji has very high requirements for humidity and temperature. As the demand for koji quality becomes higher and higher, storing koji in multiple layers and densely on shelves can facilitate the control of temperature and humidity, effectively improve production efficiency and reduce production costs. In order to allow the microorganisms on the koji blocks to reproduce better, the koji blocks need to be turned over regularly during storage. Generally, turning over is done manually, but manual turning over is time-consuming and labor-intensive. Therefore, with the development of the liquor industry, koji turning devices have also come into being.

[0003] For example, a Chinese patent (publication number: CN117163652A) discloses a koji turning robot and a koji turning system. The koji turning robot is used to be set on a walking track in the koji room and can walk in the koji room along the walking track. The koji turning robot includes a frame and a clamping component. The frame is provided with an X-axis track, and a Y-axis track is slidably provided on the X-axis track. The clamping component is movably set on the Y-axis track. The clamping component includes a mounting seat and a clamp. The mounting seat can move vertically up and down relative to the Y-axis track, and the clamp can be horizontally rotatably set on the mounting seat. The clamp is used to clamp the koji block and drive the koji block to flip horizontally and vertically. The koji turning robot can be suitable for clamping and flipping the koji blocks in the traditional liquor brewing industry to realize automated koji turning operations. In addition, there is no need to use customized koji frames in the koji turning operations, which can greatly reduce project investment and effectively reduce external factors.

[0004] However, the device is not efficient enough. The robot simply replaces manpower to turn the koji, and the koji materials still need to be turned over one by one.

[0031] In addition, the flipping mechanism 5 includes a driving motor 501 fixed to the left side wall of the inner cavity of the box body 1, and a reducer 502 is fixed to the bottom of the inner cavity of the box body 1 and to the right side of the driving motor 501. The reducer 502 can increase the output torque by reducing the rotation speed, helping the driving motor 501 to smoothly drive multiple curved blocks to flip and clamp. The input end of the reducer 502 is fixed to the output shaft of the driving motor 501, and the output shaft of the reducer 502 is fixed with a driving shaft 503 rotatably connected to the stabilizing plate 3 through a bearing. The right wall of the box body 1 is rotatably connected to two driven shafts 504 that pass through the stabilizing plate 3 through a bearing. The stabilizing plate 3 can provide stable support force for the driving shaft 503 and the two driven shafts 504 to ensure smooth and stable operation of the device. The outer surface of the driving shaft 503 is fixed with a driving gear 505. A driven gear 506 meshing with the driving gear 505 is fixed on the inner side of each driven shaft 504. The two driven gears 506 are respectively meshed with the outer top and inner bottom of the driving gear 505. The internal and external meshing method can ensure that the two driven gears 506 rotate in opposite directions. The outer surfaces of the two driven shafts 504 are threadedly connected with racks 507. The two driven gears 506 rotate in opposite directions, driving the two driven shafts 504 to rotate in opposite directions, driving the two racks 507 to move in opposite directions. The opposite sides of the two racks 507 are fixed with limit blocks 508 extending into the top wall of the box body 1 and the limit plate 4 respectively.

Since it is a driving gear 505 that drives the two driven gears 506 to rotate, the outer meshing pitch circle diameter of the driving gear 505 must be larger than the inner meshing pitch circle diameter. In order to ensure that the two driven gears 506 have the same angular velocity, the two driven gears 506 are required to have different pitch circle diameters.

[0034] Furthermore, each output component 509 includes an output rod 5091 rotatably connected to the rear side wall of the box body 1 through a bearing, and a small gear 5092 engaged with two racks 507 is fixed to the outer surface of the output rod 5091.

The outer surface of the transmission rod 5101 and the outer surface of the flip cylinder 5102 are fixed with locking structures 5103 respectively located on the inner side of the flip cylinder 5102 and passing through the front side wall of the box body 1. By installing the two locking structures 5103 in reverse, two rotation output directions can be achieved to achieve two motion effects.

[0038] In this embodiment, the shock-absorbing spring is an auxiliary structure, and the main clamping is still achieved by the movement of the clamping claw 5109. The shock-absorbing spring can make up for the clamping gap and effectively protect the curved block.

[0039] Please refer again Figure 1 In order to ensure stable operation of the device, the lifting assembly 6 in this embodiment includes an oil tank 601 fixed to the inner bottom wall of the box body 1. The oil tank 601 can provide the necessary hydraulic oil for the lifting assembly 6.

[0041] In this embodiment, the turning efficiency can be effectively improved by height adjustment and automatic clamping and turning, and the power is output simultaneously through multiple small gears 5092, so that the bending blocks are turned at the same time, further improving the turning efficiency.

[0042] See also Figure 6 In order to improve the overall convenience of use, multiple groups of koji racks 7 are fixed on the ground in this embodiment. A layer of wooden boards is laid on the koji racks 7. The wooden boards can prevent the koji blocks from contacting the koji racks 7 to ensure the fermentation quality of the koji blocks. Multiple koji blocks are placed on each layer of the koji racks 7, and multiple positioning rods 8 are fixed on the top of each koji rack 7, two in a group, respectively located on both sides of the koji blocks.

[0043] In the embodiment, the positioning rod 8 on the koji shelf 7 can facilitate the workers to quickly place the koji to the appropriate position, so as to ensure that the device can smoothly clamp and turn the koji, and further improve the efficiency of the overall koji turning.

[0044] It should be noted that the device is convenient to use, and when not in use, the device can be pulled to other positions for placement, saving space, and when in use, the koji turning efficiency is high, and it is very convenient to place the koji or turn the koji, and the koji turning efficiency can be further improved by writing the program in advance to perform mechanical repeated work.

[0045] The electrical components appearing in the text are all electrically connected with the controller and the power supply, the control mode of the present application is controlled by the controller, the control circuit of the controller can be realized by simple programming by those skilled in the art, the power supply provided by the battery also belongs to the common knowledge in the art, and the present application is mainly used to protect the mechanical device, so the control mode and the circuit connection of the present application will not be explained in detail.

[0046] The working principle of the above embodiment is as follows:

[0047] Before use, the worker holds the handrail, and then reversely starts the lifting assembly 6, the hydraulic pump 603 sucks out the hydraulic oil in the hydraulic cylinder 605, promotes the piston 606 to drive the push rod 607 to move upwards, realizes height reduction, ensures that the universal wheel 2 smoothly contacts the ground, and pushes the device to the position opposite to the koji block.

[0048] The driving motor 501 is started to output power to the speed reducer 502, the speed reducer 502 reduces the speed and increases the torque, and then outputs power to the driving gear 505 on the driving shaft 503 to rotate, further drives the two driven gears 506 to rotate in opposite directions, drives the two driven shafts 504 to rotate in opposite directions, and under the cooperation of the two limiting blocks 508, the two racks 507 move in opposite directions, promote the pinion 5092 to rotate, and the power is output by the output rod 5091.

[0049] When the upper rack 507 moves to the right and the lower rack 507 moves to the left, the locking structure 5103 fixed to the outer surface of the transmission rod 5101 will be locked, and the locking structure 5103 fixed to the outer surface of the turning cylinder 5102 will be unlocked, and the power of the output rod 5091 will pass through the transmission rod 5101, the turning cylinder 5102 and the protective shell 5106 in turn, thereby promoting the clamping jaw 5109 to rotate, and after the clamping jaw 5109 rotates, the device is pushed to the koji block direction until the clamping jaw 5109 is located on both sides of the koji block.

[0050] When in use, the lifting assembly 6 is started, and the liquid pump 603 sucks the hydraulic oil in the oil tank 601 into the hydraulic cylinder 605, causing the piston 606 to move and the push rod 607 to move, and the reflux hole can balance the pressure difference in the four hydraulic cylinders 605, further ensuring the lifting of the device and promoting the stability of the device. Then the drive motor 501 is started in the reverse direction, causing the rack 507 located above to move to the left and the rack 507 located below to move to the right. At this time, the locking structure 5103 fixed to the outer surface of the transmission rod 5101 will be unlocked, and the locking structure 5103 fixed to the outer surface of the turning cylinder 5101 will be unlocked. The locking structure 5103 fixed on the outer surface of 102 will be locked, and the power is transmitted from the output rod 5091 through the transmission rod 5101, the limit cylinder 5104, and the connecting rod 5105 to the active bevel gear 5108, driving the two driven bevel gears to rotate, and further driving the two threaded rods 5107 to rotate. Since the two threaded rods 5107 rotate in different directions, the two clamping jaws 5109 will move in opposite directions with the cooperation of the threaded rods 5107 and the stabilizing block, clamping the curved block. After clamping, the lifting assembly 6 is started to increase the height.

[0051] Then start the drive motor 501, causing the upper rack 507 to move to the right. When the lower rack 507 moves to the left, the locking structure 5103 fixed to the outer surface of the transmission rod 5101 will be locked, and the locking structure 5103 fixed to the outer surface of the flip cylinder 5102 will be unlocked. The power of the output rod 5091 will pass through the transmission rod 5101, the flip cylinder 5102, and the protective shell 5106 in turn, thereby causing the clamping claw 5109 to rotate, realizing the flipping of the koji block. After the flipping is completed, the lifting assembly 6 is controlled to lower the height, thereby placing the koji back in place.

[0052] When the block is flipped, the driving motor 501 is started in the reverse direction, causing the rack 507 at the top to move to the left and the rack 507 at the bottom to move to the right. At this time, the locking structure 5103 fixed to the outer surface of the transmission rod 5101 will be unlocked, and the locking structure 5103 fixed to the outer surface of the flip cylinder 5102 will be locked. The power is transmitted from the output rod 5091 through the transmission rod 5101, the limit cylinder 5104, and the connecting rod 5105 to the active bevel gear 5108, driving the two driven bevel gears to rotate. However, since the two threaded rods 5107 have been flipped, the two threaded rods 5107 are reversed, and the original rotation direction of the active bevel gear 5108 has not changed. At this time, the rotation directions of the two threaded rods 5107 are opposite to the original, which can smoothly cause the clamping claw 5109 to loosen, and then the lifting assembly 6 is started in the reverse direction, causing the height of the device to become lower, the universal wheel 2 contacts the ground, and the device is pushed to move to the next group of koji, and the above process is repeated.
