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 the koji in multiple layers and densely on shelves can conveniently control 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, the koji is turned over manually, but manual turning 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 a 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 arranged 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 arranged 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, thereby greatly reducing project investment and effectively reducing 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. The turning efficiency is not high enough. Therefore, a fully automatic koji turning device for koji fermentation is proposed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 to 5 A fully automatic koji turning device for koji fermentation in this embodiment includes a box body 1, a plurality of freely rotatable universal wheels 2 are fixed to the bottom of the box body 1, the universal wheels 2 can improve the portability of the device as a whole, a stabilizing plate 3 is fixed between the top wall and the bottom wall of the inner cavity of the box body 1, a limiting plate 4 whose other end is fixed to the stabilizing plate 3 is fixed to the right side wall of the inner cavity of the box body 1, a turning mechanism 5 capable of efficiently turning the koji is provided on the inner left wall of the box body 1, and a lifting component 6 for stably changing the height is provided on the inner bottom wall of the box body 1 and on the left side of the stabilizing plate 3.

[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 at the bottom of the inner cavity of the box body 1 and on the right side of the driving motor 501. The reducer 502 can increase the output torque by reducing the rotation speed, and help 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 penetrate the stabilizing plate 3 through bearings. 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, and the two driven gears 506 are respectively meshed with the outer top and inner bottom of the driving gear 505, and the inner and outer meshing method can ensure that the two driven gears 506 rotate in opposite directions, and 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, and 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, and a plurality of output components 509 are provided on the rear side wall of the inner cavity of the box body 1, and the front of each output component 509 is provided with a grabbing portion 510 penetrating the front side wall of the box body 1.

[0032] It needs to be further explained that the inner top wall of the box body 1 and the top of the limit plate 4 are both provided with limit grooves, and the two limit blocks 508 are movably connected to the two limit grooves respectively. The limit grooves can limit the limit blocks 508 to further ensure the smooth movement of the two racks 507. Two stabilizing holes are provided on the stabilizing plate 3, and the two driven shafts 504 both pass through the stabilizing holes and are rotatably connected to the side walls of the stabilizing holes through bearings. The bearings can help the two driven shafts 504 rotate more stably.

[0033] It can be known that an annular meshing groove is provided on the left side of the driving gear 505, and a plurality of internal teeth are fixed on the side wall of the meshing groove. The internal teeth on the meshing groove can mesh with one of the driven gears 506. A plurality of external teeth are fixed on the outer side of the driving gear 505. The driving gear 505 meshes with the two driven gears 506 through the internal teeth and the external teeth respectively. The internal and external meshing can ensure that the rotation directions of the two driven gears 506 are opposite. The pitch circle diameter of the driven gear 506 meshing with the outside of the driving gear 505 is larger than the pitch circle diameter of the driven gear 506 meshing with the inside of the driving gear 505. Since one driving gear 505 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 assembly 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 meshing with two racks 507 is fixed to the outer surface of the output rod 5091. The two racks 507 drive multiple small gears 5092 to further realize the simultaneous flipping of multiple curved blocks, thereby improving the efficiency of flipping. Each grasping portion 510 includes a transmission rod 5101 fixed to the front end of the output rod 5091, and the outer surface of the transmission rod 5101 is movably connected to a flip cylinder 5102 that passes through the front side wall of the box body 1. The outer surfaces of the transmission rod 5101 and the flip cylinder 5102 are fixed with locking structures 5103 that are respectively located on the inner side of the flip cylinder 5102 and pass through the front side wall of the box body 1. By reversely installing the two locking structures 5103, two rotation output directions can be realized to achieve two motion effects, and the front of the flip cylinder 5102 is fixedly connected to a protective shell 5106.

[0035] In addition, each flip cylinder 5102 is provided with a transmission hole, a limiting hole and a connecting hole. The transmission hole is connected to the limiting hole, the limiting hole is connected to the connecting hole, the transmission hole is connected to the limiting hole, and the limiting hole and the connecting hole are connected to each other, which can help the power to be transmitted smoothly. Each transmission rod 5101 passes through the transmission hole and extends into the limiting hole. Each grasping part 510 also includes a limiting cylinder 5104 fixed to the front side of the transmission rod 5101 and movably connected to the side wall of the limiting hole. The limiting cylinder 5104 cooperates with the limiting hole to improve the stability of the grasping part 510. A connecting rod 5105 that passes through the connecting hole and extends into the protective shell 5106 is fixed to the front side of each limiting cylinder 5104. A driving bevel gear 5108 is fixed on the surface, and the top and bottom of the inner cavity of the protective shell 5106 are rotatably connected to threaded rods 5107 through bearings. A driven bevel gear meshing with the driving bevel gear 5108 is fixed on the opposite side of the two threaded rods 5107. The driving bevel gear 5108 drives the two driven bevel gears to rotate, and the rotation directions of the two driven bevel gears are opposite. The outer surfaces of the two threaded rods 5107 are fixed with external threads, and the two external threads have the same rotation direction. The driven bevel gears drive the two threaded rods 5107 to rotate in opposite directions to achieve relative movement or opposite movement of the clamping jaws 5109. The outer surfaces of the two threaded rods 5107 are threadedly connected with the clamping jaws 5109 that penetrate the front side wall of the protective shell 5106.

[0036] It should be further explained that each locking structure 5103 is composed of an outer shell, four elastic steel sheets, four hinge shafts, four pawls and a ratchet. The four elastic steel sheets, four hinge shafts and four pawls can improve the stability of power transmission and the stability of the overall force of the locking structure 5103. The front side wall of the box body 1 is provided with a plurality of stabilizing holes. Each grabbing portion 510 is provided with a self-locking component. Each self-locking component is composed of two locking structures 5103 installed in opposite directions. The two locking structures 5103 are installed in opposite directions to ensure that no matter what direction of rotation the power input to the transmission rod 5101 is, the power can be smoothly transmitted. The outer shell is fixed to the inner wall of the stabilizing hole and the inner wall of the limiting hole respectively, and the two ratchets are fixed to the outer surfaces of the transmission rod 5101 and the flip cylinder 5102 respectively. The ratchet is an existing structure and is widely used in structures such as bicycles. The four hinge shafts are fixed to the bottom wall of the inner cavity of the outer shell, and each hinge shaft is hinged to a pawl that abuts against the outer surface of the ratchet. The pawl holds the ratchet, and when the ratchet rotates in the direction of the pawl, the ratchet can rotate smoothly. When the ratchet rotates against the direction of the pawl, the pawl will hold the ratchet, thereby locking the ratchet. The inner wall of the outer shell is fixed to four elastic steel sheets abutting against the pawls, and the elastic steel sheets can provide force for the pawls to abut against the ratchet.

[0037] It can be known that a stabilizing block that abuts against the rear wall of the inner cavity of the protective shell 5106 is fixed to the rear side of each clamping jaw 5109, and multiple shock-absorbing springs are fixed to the opposite side of each clamping jaw 5109. A stabilizing plate is fixed to the opposite side of the multiple shock-absorbing springs, and the shock-absorbing springs are existing structures.

[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 component 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 necessary hydraulic oil for the lifting component 6. The left side of the oil tank 601 is fixedly connected to a liquid pump 603 fixed to the inner bottom wall of the box body 1. The front and rear sides of the liquid pump 603 are respectively fixedly connected to two output pipes 604 fixedly connected to the inner bottom wall of the box body 1. Four hydraulic cylinders 605 are fixedly connected to the bottom of the box body 1. The inner side of each hydraulic cylinder 605 is movably connected to a piston 606. The piston 606 can improve the overall sealing performance. The bottom of each piston 606 is fixed with a push rod 607 that penetrates the bottom wall of the hydraulic cylinder 605. The movement of the piston 606 pushes the push rod 607 to move.

[0040] In addition, four input holes are provided on the bottom wall of the box body 1, which are respectively connected to the four output pipes 604. The other ends of the four input holes are respectively connected to the hydraulic cylinders 605. The input holes can smoothly transfer the hydraulic oil to the hydraulic cylinders 605. Four reflux holes are provided at the bottom of the box body 1, which are connected to the hydraulic cylinders 605. The four reflux holes are interconnected. The reflux holes are used to balance the pressure in each hydraulic cylinder 605 to ensure the stability of the device for height adjustment. Handrails are fixed on both sides of the box body 1 to provide portability. A backup battery is fixed on the left side wall of the inner cavity of the box body 1 and above the drive motor 501. The use of a backup battery can ensure that the device can operate smoothly even if there is no power supply or a power outage in the room.

[0041] In this embodiment, the turning efficiency can be effectively improved by adjusting the height and automatically clamping and turning. 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, two in a group, are fixed on the top of each koji rack 7, which are located on both sides of the koji blocks.

[0043] In this embodiment, the positioning rod 8 on the koji rack 7 can facilitate the staff to quickly place the koji until it is suitable, thereby ensuring that the device can smoothly clamp and flip the koji, further improving the overall koji turning efficiency.

[0044] It should be noted that the device is easy to use. When not in use, the device can be pulled to other locations and placed, saving space. It is also efficient in turning the koji when in use. It is convenient for placing the koji or turning the koji, and can perform mechanized repetitive work by writing programs in advance, further improving the efficiency of turning the koji.

[0045] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The power supply provided by the battery is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

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

[0047] Before use, the staff holds the handrail and then starts the lifting assembly 6 in reverse. The liquid pump 603 sucks out the hydraulic oil in the hydraulic cylinder 605, prompting the piston 606 to drive the push rod 607 to move upward, thereby lowering the height and ensuring that the universal wheel 2 contacts the ground smoothly, so that the device is pushed to face the curved block.

[0048] Start the drive motor 501 to output power to the reducer 502. After the reducer 502 reduces the speed and increases the torque, it outputs the power to the driving gear 505 on the driving shaft 503 to rotate, further driving the two driven gears 506 to rotate in opposite directions, driving the two driven shafts 504 to rotate in the opposite direction, and with the cooperation of the two limit blocks 508, the two racks 507 move in opposite directions, causing 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 flip cylinder 5102 will be unlocked, and the power of the output rod 5091 will pass through the transmission rod 5101, the flip cylinder 5102, and the protective shell 5106 in sequence, thereby prompting the clamping jaw 5109 to rotate. When the clamping jaw 5109 rotates, it pushes the device in the direction of the bending block until the clamping jaws 5109 are located on both sides of the bending 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 drive 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, and then the drive motor 501 is started in the reverse direction, causing the rack 507 located at the top to move to the left and the rack 507 located 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 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 rod 5107 and the stabilizing block at this time, clamp the curved block, and after clamping, start the lifting assembly 6 to increase the height.

[0051] Then start the driving 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 turning cylinder 5102 will be unlocked. The power of the output rod 5091 will pass through the transmission rod 5101, the turning cylinder 5102, and the protective shell 5106 in sequence, thereby causing the clamping claw 5109 to rotate, realizing the turning of the koji block. After the turning is completed, the lifting assembly 6 is controlled to lower the height, thereby placing the koji back to its original position.

[0052] After the block is flipped, the drive motor 501 is started in reverse, 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 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 at this time, while 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 ones, which can smoothly cause the clamping claw 5109 to loosen, and then the lifting assembly 6 is started in reverse to cause 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.
