The fermented tofu in the lower layer is designated B1, B2, B3, B4, B5, and B6. The fermented tofu in the upper layer is designated T1, T2, T3, T4, T5, and T6. The bottom layer of fermented tofu is arranged perpendicular to the upper layer of fermented tofu.

[0042] Reference Figure 3 and Figure 4 A fermented bean curd bottling device includes an equipment frame 1, a dividing plate operating mechanism 2, a first grabbing mechanism 3, a second grabbing mechanism 4, a third grabbing mechanism 5, and a fourth grabbing mechanism 6. By using the fermented bean curd bottling device of the present invention, 12 pieces of fermented bean curd can be put into bottles in a certain order to achieve the bottling of fermented bean curd.

[0043] The equipment frame 1 primarily supports the entire machine and connects several related modules. Two fermented bean curd bottling production lines are installed on the frame. The frame comprises a bottom bracket 11, support rods 12, and a top plate 13. Support rods 12 are secured to the side walls of bottom bracket 11, and top plate 13 is affixed to the tops of support rods 12. The indexing plate mechanism 2 primarily switches the fermented bean curd bottles relative to the various gripping mechanisms and positions for loading, rotating, and unloading bottles, enabling continuous operation to form an automated production line.

[0044] Reference Figure 5-Figure 14 The indexing plate operating mechanism 2 includes an indexing plate body 21, a rotary clamping mechanism 22, a paddle bottle entry connecting rod mechanism 23, a bottom support plate 24, a clamping pneumatic guide drive mechanism 25, a paddle bottle entry pneumatic drive mechanism, a bottle rotation trajectory control mechanism 26, and a paddle position control and protection mechanism 27. The bottom support plate 24 is fixed to the bottom bracket 11 by bolts. A rotating shaft 242 is fixed to the bottom support plate 24. The indexing plate body 21 is fixed to the top of the rotating shaft 242. An intermittent drive motor 241 that drives the rotating shaft 242 is fixed to the bottom of the bottom support plate 24.

[0045] The dividing plate body 21 is a circular plate. According to the production process requirements and the structural characteristics of the dividing plate operating mechanism 2, the dividing plate body 21 is divided into eight working position spaces in the circumferential direction. Each spatial position corresponds to a work station. These eight work stations are the first work station 211, the second work station 212, the third work station 213, the fourth work station 214, the fifth work station 215, the sixth work station 216, the seventh work station 217 and the eighth work station 218.

[0046] Below, the work content of the above eight workstations is explained in detail.

[0047] The first station 211: loading bottles and positioning and clamping them.

[0048] The second station 212: grabs and transfers fermented bean curd B1, B3, B4, B6 to bottles and packs them in the order and position required. After packing is completed, the indexing plate body 21 rotates to the third station 213 according to the work cycle time requirement.

[0050] The fourth station 214 is a bottle rotation station. The bottle and the fixture are rotated 90 degrees relative to the indexing turntable under the action of the bottle rotation trajectory control mechanism 26 below the indexing turntable body 21 and enter the fifth station 215.

[0051] The fifth station 215: grabs and transfers fermented bean curd T1, T3, T4, T6 to the bottle and packs them in the order and position required. After packing is completed, the indexing plate body 21 rotates to the sixth station 216 according to the work cycle time requirement.

[0052] The sixth station 216: grab and transport fermented bean curd T2, T5 to the bottle and pack them in the order and position. After packing is completed, the indexing plate body 21 rotates to the seventh station 217 according to the working cycle time requirement.

[0053] The seventh station 217 is a bottle rotation station. The bottle and the fixture are rotated 90 degrees relative to the indexing turntable under the action of the bottle rotation trajectory control mechanism 26 below the indexing turntable body 21 and enter the eighth station 218.

[0054] The eighth station 218: The clamping mechanism 22 is rotated to release the fermented bean curd bottle and place it in the container. After the container is placed in the container, the indexing plate 21 rotates according to the work cycle time and returns to the first station 211, and the next work cycle begins.

[0055] The first grabbing mechanism 3 is responsible for grabbing the lower layers of fermented tofu (B1, B3, B4, and B6) into bottles. Its working position is the second station 212, and the first grabbing mechanism 3 is located directly above the second station 212. The second grabbing mechanism 4 is responsible for grabbing the lower layers of fermented tofu (B2 and B5) into bottles. Its working position is the third station 213, and the second grabbing mechanism 4 is located directly above the third station 213. The third grabbing mechanism 5 is responsible for grabbing the upper layers of fermented tofu (T1, T3, T4, and T6) into bottles. Its working position is the fifth station 215, and the third grabbing mechanism 5 is located directly above the fifth station 215. The fourth grabbing mechanism 6 is responsible for grabbing the upper layers of fermented tofu (T2 and T5) into bottles. Its working position is the sixth station 216, and the fourth grabbing mechanism 6 is located directly above the sixth station 216.

[0056] Each workspace on the indexing plate body 21 is provided with a rotary clamping mechanism 22, which positions and clamps the fermented bean curd bottle. A plurality of mounting holes 219 are evenly distributed on the indexing plate body 21, with each rotary clamping mechanism 22 corresponding to one mounting hole 219. The rotary clamping mechanism 22 includes a fixed plate 222 and a follower planetary turntable 221. The fixed plate 222 is located below the indexing plate body 21 and is fixedly connected to the bottom of the indexing plate body 21. A rotary core shaft 2221 is rotatably connected above the fixed plate 222. The follower planetary turntable 221 is located in the mounting hole 219 and is fixed to the top of the rotary core shaft 2221.

[0057] A bottle placement guide block 223 is fixed on the follower planetary turntable 221. The bottle placement guide block 223 is U-shaped, and the fermented bean curd bottle is located in the U-shaped cavity of the bottle placement guide block 223. A first clearance groove 2231 is opened on the bottle placement guide block 223.

[0058] A support and fixing assembly 224 is fixed beneath the fixed plate 222. This assembly includes a support and fixing block 2241 and a central hinge axis 2242 for the clamping jaws. The rotary core shaft 2221 passes through the fixed plate 222 and is fixed to the support and fixing block 2241. A second clearance groove 2243 is defined in the support and fixing block 2241, and the central hinge axis 2242 for the clamping jaws is fixed to the wall of the second clearance groove 2243. A bottle clamping jaw assembly 225 is mounted on the support and fixing block 2241. The bottle clamping jaw assembly 225 includes an upper connecting rod 2251 and a lower connecting rod 2252. Two upper connecting rods 2251 and two lower connecting rods 2252 are provided, intersecting each other and articulated at the intersection via the central hinge axis 2242 for the clamping jaws.

[0059] A positioning guide spindle 2244 is fixed to the bottom of the support and fixing block 2241. A compression return spring protective sleeve 227 is sleeved on the bottom of the positioning guide spindle 2244. A compression return spring 226 is fixed between the bottom of the support and fixing block 2241 and the compression return spring protective sleeve 227. The compression return spring sleeve 227 sleeves on the positioning guide spindle 2244. A lower connecting rod 2252 corresponds to each upper connecting rod 2251. One end of the lower connecting rod 2252 is hinged to the bottom end of the upper connecting rod 2251, and the other end of the lower connecting rod 2252 is hinged to the compression return spring protective sleeve 227.

[0060] The follower planetary turntable 221 has a third clearance slot 2212 for the upper connecting rod 2251 to rotate. The upper connecting rod 2251 passes through the first clearance slot 2231. The top of the upper connecting rod 2251 passes through the third clearance slot 2212 of the follower planetary turntable 221 and the first clearance slot 2231 of the bottle insertion guide block 223. A clamping block 2253 is fixed to the top of each upper connecting rod 2251 on the side closest to each other, contacting the fermented bean curd bottle. Below the first station 211 and below the eighth station 218, a clamping pneumatic guide drive mechanism 25 is installed. This pneumatic guide drive mechanism 25 drives the compression return spring protective sleeve 227 upward, thereby releasing the two upper connecting rods 2251 from the fermented bean curd bottle. The clamping pneumatic guide drive mechanism 25 is a first pneumatic cylinder, whose piston rod pushes the compression return spring protective sleeve 227 upward. The piston rod of the first cylinder can contact the bottom of the compression return spring protection sleeve 227, but there is no connection relationship between them.

[0061] Before placing the fermented bean curd bottle at the first station 211, the first cylinder piston rod is lifted upward, releasing the two upper connecting rods 2251. After the fermented bean curd bottle is placed at the first station 211, the cylinder piston rod is lowered. The compression return spring protective sleeve 227, under the action of the compression return spring 226, moves downward, causing the two upper connecting rods 2251 to clamp the fermented bean curd bottle. When the fermented bean curd bottle rotates to the eighth station 218, it needs to be removed. The first cylinder below the eighth station 218 pushes the compression return spring protective sleeve 227 upward, causing the two upper connecting rods 2251 to release the fermented bean curd bottle, allowing the fermented bean curd bottle to be removed.

[0062] The rotary clamping mechanism 22 also includes a rotation track lever assembly 228, which includes a steering lever 2281 and a guide wheel 2282. The steering lever 2281 is fixed to the side wall of the support and fixing block 2241, and the guide wheel 2282 is rotatably connected to the steering lever 2281. The bottle rotation track control mechanism 26 includes a guide ring plate 261 and a ring plate support rod 262. The ring plate support rod 262 is fixed between the guide ring plate 261 and the bottom support plate 24. Four ring plate support rods 262 are arranged around the guide ring plate 261. The bottom of the guide ring plate 261 defines a second track groove 263, along which the guide wheel 2282 slides. A torsion return spring 2283 is arranged between the bottom of the follower planetary turntable 221 and the fixed plate 222. A blocking block 2211 is fixed to the bottom of the follower planetary turntable 221, and one end of the torsion return spring 2283 abuts against the blocking block 2211; a plug-in slot 2222 is opened on the top surface of the fixed plate 222, and the other end of the torsion return spring 2283 is inserted into the plug-in slot 2222.

[0063] When the follower planetary turntable 221 rotates from the third station 213 to the fifth station 215 along with the index plate body 21, the follower planetary turntable 221 rotates 90 degrees. When the follower planetary turntable 221 rotates, the guide wheel 2282 moves along the second track groove 263, rotating the steering lever 2281 90 degrees, thereby rotating the follower planetary turntable 221 and the fermented bean curd bottle 90 degrees.

[0064] The second track groove 263 includes an arcuate groove 2631, a folded groove 2632, and a straight groove 2633. The arcuate grooves 2631 at both ends separate the folded groove 2632 from the straight groove 2633. The arcuate grooves 2631, the straight grooves 2633, the arcuate grooves 2631, and the straight grooves 2633 together form the second track groove 263. The folded groove 2632 is located above the fourth station 214. When the guide wheel 2282 of the steering lever 2281 passes through the folded groove 2632, the steering lever 2281 begins to slowly turn. When the steering lever 2281 reaches the fifth station 215, the steering lever 2281 rotates 90 degrees (relative to the steering lever 2281 on the first station 211), thereby rotating the fermented bean curd bottle 90 degrees. When the follower planetary turntable 221 rotates from the sixth station 216 to the eighth station 218, the guide wheel 2282 on the steering lever 2281 passes through the arc groove 2631, the straight groove 2633 and the arc groove 2631. Under the action of the torsion return spring 2283, the steering lever 2281 drives the follower planetary turntable 221 to rotate 90 degrees.

[0065] Each workspace corresponds to a paddle-injection linkage mechanism 23, which includes a bottle-injection paddle 231, a lifting link 232, and a guide rod seat 237. The guide rod seat 237 is fixed to the indexing plate body 21 via bolts. A fixed hinge support 238 is fixed to the guide rod seat 237, and the bottom of the bottle-injection paddle 231 is hinged to the fixed hinge support 238. A guide rod 236 is provided on the guide rod seat 237, extending through the guide rod seat 237. A lifting angled pull plate 239 is fixed to the bottom of the guide rod 236. A pneumatic drive mechanism for the paddle-injection paddle, which drives the lifting angled pull plate 239 upward and downward, is fixed to the bottom support plate 24.

[0066] A third intermediate rod 235 is hinged to the top of the guide rod 236, and a second intermediate rod 234 is hinged to the fixed hinge support 238. The third intermediate rod 235 is hinged to the middle position of the second intermediate rod 234 on the side away from the top of the guide rod 236. A first intermediate rod 233 is arranged above the second intermediate rod 234. One end of the first intermediate rod 233 is hinged to the end of the second intermediate rod 234 away from the fixed hinge support 238. The first intermediate rod 233 is hinged to the bottle-entry paddle 231.

[0067] When the paddle-into-bottle pneumatic drive mechanism 23 drives the lifting angle pull plate 239 to move downward, the bottle-into-bottle paddle 231 is inserted into the fermented bean curd bottle to support the fermented bean curd B1, B3, B4, B6 or the fermented bean curd T1, T3, T4, T6 to prevent the fermented bean curd in the fermented bean curd bottle from tipping over (the bottle-into-bottle paddle 231 needs to be inserted into the fermented bean curd bottle before the gripper is lifted to prevent the fermented bean curd from tipping over, which will be described in detail in the subsequent gripping mechanism action).

[0068] The pneumatic drive mechanism for inserting the paddle into the bottle is a second cylinder, the piston rod of which is fixed with two paddle plates 28, arranged one above the other. The paddle position control and protection mechanism is a cylinder 271, fixed to the bottom support plate 24. The top of cylinder 271 supports the indexing plate body 21. A first track groove 272 is defined on the outer wall of cylinder 271. A guide cam 2391 is fixed to the lifting angle pull plate 239, which slides along the first track groove 272. The first track groove 272 comprises an upper groove 2721 and a lower groove 2722. Each of the upper and lower grooves 2721 and 2722 has two sections, forming a circle formed by the upper and lower grooves 2721 and 2722. A pneumatic drive mechanism for inserting a paddle into a bottle is set at the position where the upper groove 2721 and the lower groove 2722 communicate. When the guide cam 2391 slides from the upper groove 2721 to the lower groove 2722, the guide cam 2391 slides between the two paddle plates 28, and the lower paddle plate 28 supports the guide cam 2391.

[0069] When the follower planetary turntable 221 moves from the first station 211 to the second station 212, or when the follower planetary turntable 221 moves from the fifth station 215 to the sixth station 216, the guide cam 2391 slides from the upper groove 2721 to the lower groove 2722, and the guide cam 2391 slides from the upper groove 2721 to the lower paddle plate 28. When the bottle-entry paddle 231 needs to be inserted into the fermented bean curd bottle, the piston rod of the second cylinder moves downward, thereby driving the two paddle plates 28 to move downward, thereby driving the guide cam 2391, causing the bottle-entry paddle 231 to rotate downward and enter the fermented bean curd bottle.

[0070] Afterwards, the bottle-entering paddle 231 rotates with the fermented bean curd bottle. When the second grabbing mechanism 4 or the fourth grabbing mechanism 6 puts the fermented bean curd into the bottle, the bottle-entering paddle 231 is pulled out of the fermented bean curd bottle.

[0071] Reference Figure 15 、 Figure 16 and Figure 17 The first gripping mechanism 3 includes a first transverse portion 31, a first lifting portion 32, a first gripping portion 33, a second lifting portion 34, and a second gripping portion 35.

[0080] The function of the first dividing assembly 335 is to clamp the fermented bean curd B1 and B3 and place them in the bottle, and then move the fermented bean curd B1 and B3 to the sides to make way for the fermented bean curd B2 and B5 to be bottled. Before moving the fermented bean curd B1 and B3, the outer clamping claw 3324 needs to be pulled out of the bottle. The first dividing assembly 335 includes a first main shifting rod 3351, a first shifting rod 3352, and a first shifting slider 3355. A first shifting vertical guide rail 3353 is fixed to the side of the first mounting plate 3314 near the clamping shifting stepping motor 331. A slider is fixed to the side of the first main shifting rod 3351 near the first mounting plate 3314, and the slider is slidably connected to the first shifting vertical guide rail 3353. A first elongated hole 336 is formed on the first main shifting rod 3351, and the first elongated hole 336 is arranged in a vertical direction. The inner clamp lifting nut 3313 located below the clamping and shifting stepping motor 331 is threadedly connected to the inner clamping claw lifting screw 3312 . The first shifting active rod 3358 is fixed on the inner clamp lifting nut 3313 , and the first shifting active rod 3358 is inserted into the first elongated hole 336 .

[0081] Two first dispatch levers 3352 are located below the first main dispatch lever 3351. A first connecting shaft 3356 is fixed to the bottom of the first main dispatch lever 3351, and a second connecting shaft 3357 is fixed to the top of the first main dispatch lever 3351. A first dispatch transverse guide rail 3354 is fixed to the bottom of the first mounting plate 3314, and two first dispatch sliders 3355 are slidably connected to the first dispatch transverse guide rail 3354.

[0082] One end of one of the first dispatching levers 3352 is rotatably connected to the first connecting shaft 3356, and the other end of the first dispatching lever 3352 is rotatably connected to the top of one of the first dispatching sliders 3355. Another first dispatching lever 3352 also has one end rotatably connected to the first connecting shaft 3356, and the other end of the first dispatching lever 3352 is rotatably connected to the top of the other first dispatching slider 3355.

[0083] After putting fermented tofu B1, B3, B4, and B6 into the bottle, you need to separate B1 and B3, and B4 and B6, to make room for B2 and B5. After the fermented tofu B1, B3, B4 and B6 are placed on the bottom of the bottle, the clamping and shifting stepping motor 331 drives the outer clamping claw lifting screw 3311 and the inner clamping claw lifting screw 3312 to rotate, and the inner clamp lifting nut 3313 moves downward, and the inner clamp lifting nut 3313 drives the first shifting active rod 3358 to move downward. When the first shifting active rod 3358 moves to the bottom of the first elongated hole 336, the first shifting active rod 3358 abuts against the bottom end hole wall of the first elongated hole 336, driving the first main shifting rod 3351 to move downward, and the first main shifting rod 3351 drives the first shifting rod 3352 to move downward, and the first shifting slider 3355 corresponding to the first shifting rod 3352 slides along the first shifting transverse guide rail 3354, thereby driving the inner clamping claw arm 3331 and the inner clamping claw 3333 to move, so that the two inner clamping claws 3333 move away from each other. Thus, fermented bean curds B1 and B3 are separated, and fermented bean curds B4 and B6 are separated.

[0084] The clamping assembly 334 includes a roller 3342, an upper clamping slider 3343, and a lower clamping slider 3344. A mounting rod 3341 is fixed to the side wall of the U-shaped mounting plate 322. The roller 3342 is mounted on the bottom of the mounting rod 3341 and contacts the side wall of the outer clamping arm 3322. The upper clamping slider 3343 and the lower clamping slider 3344 are both fixed to the outer clamping arm 3322. When the fermented tofu needs to be clamped, the outer clamping arm 3322 moves downward a distance, and the roller 3342 contacts the lower clamping slider 3344, sliding from the inclined surface of the lower clamping slider 3344 to the vertical surface of the lower clamping slider 3344, thereby squeezing the outer clamping arm 3322. When the outer clamp arm 3322 moves downward, the inner clamp lifting nut 3313 moves upward, thereby driving the first main pull rod 3351 to move upward. When the first main pull rod 3351 is at the top, the inner clamp 3333 is closest to the corresponding outer clamp 3324. The outer clamp 3324 arm and the inner clamp 3333 arm work together to clamp the fermented tofu.

[0085] When the inner clamp lifting nut 3313 descends, the outer clamp lifting connecting plate 3321 rises, and the outer clamp arm 3322 rises along with the outer clamp lifting connecting plate 3321, causing the roller 3342 to disengage from the upper clamping slider 3343. At this time, the outer clamp 3324 is separated from the fermented bean curd. The outer clamp 3324 then continues to move upward along with the outer clamp arm 3322. When the lower clamping slider 3344 on the outer clamp arm 3322 contacts the roller 3342, the two outer clamps 3324 move toward each other, thereby facilitating the withdrawal of the outer clamp 3324 from the bottle mouth. After the outer clamp 3324 is withdrawn from the bottle mouth, the first shifting active rod 3358 abuts against the bottom end of the first elongated hole 336, driving the first main shifting pull rod 3351 to move downward.

[0094] When clamping the fermented tofu B2, the first clamping stepper motor 431 drives the clamping screw 4313 to move downward, and the clamping screw 4313 drives the clamping nut slide 4314 to move downward. When the clamping nut slide 4314 drives the second main shifting rod 4321 to move downward, the two second shifting rods 4322 push the two second shifting slide blocks 4329 to move away from each other, so that the distance between the two B2 clamping jaws 4333 in the same group is wider than the thickness of one fermented tofu. Then the third lifting part 42 drops to a certain height, and the first clamping stepper motor 431 drives the clamping screw 4313 to move, thereby driving the second shifting active rod 4327 to move upward. When the second shifting active rod 4327 is pressed against the top side wall of the second long hole, and the second return spring 4328 restores its deformation, the two B2 clamping jaws 4333B2 clamp the fermented tofu B2.

[0100] The longitudinal fine-motion assembly 544 of the clamping jaw is located below the transverse fine-motion assembly 543 of the clamping jaw. The transverse fine-motion assembly 543 of the clamping jaw includes a transverse fine-motion stepper motor 5431, a transverse fine-motion ball screw 5432 and a transverse fine-motion nut slide 5433. The transverse fine-motion stepper motor 5431 is fixed on the first connecting plate 5434.

The transverse fine-motion nut slide 5433 is installed on the transverse fine-motion ball screw 5432. A second connecting plate 5447 is fixed on the transverse fine-motion nut slide 5433.

[0101] The jaw longitudinal fine-motion assembly 544 includes a longitudinal fine-motion stepper motor 5441, a longitudinal fine-motion ball screw 5442, a longitudinal fine-motion nut slide 5443, a longitudinal fine-motion clamping slide 5444, a longitudinal fine-motion secondary slide 5445, and a secondary slide return spring 5446. The longitudinal fine-motion stepper motor 5441 is fixed to the second connecting plate 5447, and the longitudinal fine-motion ball screw 5442 is connected to the output shaft of the longitudinal fine-motion stepper motor 5441.

[0102] A third connecting plate 545 is fixed to the side of the first connecting plate 5434 away from the transverse fine-motion stepping motor 5431. A secondary longitudinal fine-motion slide rail 5445 is slidably connected to the third connecting plate 545. A fourth connecting plate 546 is fixed to the side of the secondary longitudinal fine-motion slide rail 5445 away from the third connecting plate 545. A longitudinal fine-motion clamping slide rail 5444 is slidably connected to the fourth connecting plate 546. The longitudinal fine-motion nut slide 5443 is fixedly connected to the longitudinal fine-motion clamping slide rail 5444. A stopper 5461 is fixed to the end of the third connecting plate 545 away from the clamping direction, and a stopper 5461 is fixed to the end of the fourth connecting plate 546 closer to the clamping direction.

[0103] The sixth gripping part 55 includes a T4 clamping arm 551, a T4 clamping arm connecting plate 552 and a T4 clamping jaw 553, wherein one T4 clamping jaw arm 551 is fixedly connected to the longitudinal fine-motion clamping slide rail 5444, and the other T4 clamping jaw arm 551 is fixed to the longitudinal fine-motion secondary slide rail 5445, the T4 clamping jaw arm connecting plate 552 is fixed below the T4 clamping jaw arm 551, and the T4 clamping jaw 553 is fixed at the bottom of the T4 clamping jaw arm connecting plate 552.

[0104] To clamp the fermented tofu T4, the longitudinal fine-motion stepper motor 5441 drives the longitudinal fine-motion nut slide 5443, which in turn moves the longitudinal fine-motion clamping rail 5444, thereby moving one of the T4 clamping jaws 553. Meanwhile, the other T4 clamping jaw 553 remains stationary. When the longitudinal fine-motion clamping rail 5444 reaches the end of the adjustment screw 5462 on the stopper 5461 of the fourth connecting plate 546, the longitudinal fine-motion clamping rail 5444 drives the longitudinal fine-motion secondary rail 5445 to move. The longitudinal fine-motion secondary rail 5445 is then pulled in the opposite direction by the secondary rail return spring 5446. As the tension of the secondary rail return spring 5446 increases, the fermented tofu T4 is clamped. Driven by the longitudinal fine-motion clamping rail 5444 and the longitudinal fine-motion secondary rail 5445, respectively, the two T4 clamping jaws 553 clamp the fermented tofu T4.

[0105] When fermented tofu T4 is released, the longitudinal fine-motion stepper motor 5441 drives the longitudinal fine-motion nut slide 5443 in the opposite direction. When one end of the longitudinal fine-motion secondary slide rail 5445 moves to the end of the adjustment screw 5462 on the stop 5461 of the third connecting plate 545, the secondary slide rail return spring 5446 returns to its original length. The function of the adjustment screw 5462 is to adjust the tension of the secondary slide rail return spring 5446 during extension, preventing excessive tension from damaging the fermented tofu. The seventh lifting portion 56 has the same structure as the sixth lifting portion 54, and the seventh gripping portion 57 has the same structure as the sixth gripping portion 55.

[0106] The working steps of the third gripping mechanism 5 are:

[0107] Step 1: Grab fermented tofu T1, T2, T3, and T4;

[0108] While the collection of fermented tofu T1, T2, T3, and T4 occurs simultaneously, their stacking is completely different, with different timings. These are discussed separately here. First, due to the objective requirements of the fermented tofu collection and stacking process, the salt blocks on the upper layer are stacked perpendicular to those on the lower layer. Furthermore, due to space limitations, the stacking order of T1, T2, T3, and T4 on the second layer is: T1 and T3 first, T4 second, and T6 last.

[0109] The grabbing, moving and stacking of fermented bean curd T1 and T3 are the same as those of fermented bean curd B1 and B3, except that the stacking height is one fermented bean curd block higher than the bottom layer.

[0110] The grabbing of fermented tofu T4 and T6 is a bilaterally symmetrical operation, so the grabbing of fermented tofu T4 will be used as an example. First, the third transverse displacement unit 51 drives the sixth lifting unit 54 and the sixth gripping unit 55 from the zero position of the control system to directly above the fermented tofu jig. The sixth lifting unit 54 drives the sixth gripping unit 55 downward. Based on the specific design, each gripping jaw of the gripper component is ideally positioned directly above the corresponding fermented tofu (salt block) to be gripped. When the sixth gripping unit 55 descends to a certain height, each fermented tofu salt block to be gripped is within the optimal gripping space of each gripper's specific jaw. Fermented tofu T1, T3, T4, and T6 are grabbed simultaneously. When grabbing fermented tofu T4, the longitudinal fine-motion stepper motor 5441 drives the longitudinal fine-motion nut slide 5443 to slide. The longitudinal fine-motion nut slide 5443 drives the longitudinal fine-motion clamping slide 5444 to move, thereby moving one of the T4 clamping jaws 553. When the longitudinal fine-motion clamping slide 5444 moves to the position of the stop block 5461, the longitudinal fine-motion clamping slide 5444 drives the longitudinal fine-motion secondary slide 5445 to move. After the longitudinal fine-motion secondary slide 5445 moves a certain distance along with the longitudinal fine-motion clamping slide 5444, the two T4 clamping jaws 553 clamp the fermented tofu T4. At this time, the longitudinal fine-motion secondary slide 5445 is pulled by the secondary slide return spring 5446. Fermented tofu T6 is clamped in the same way. After the fermented tofu T1, T3, T3, and T6 are clamped, it is ready for the next step of "fermented tofu transfer."

[0111] Step 2: Transfer of fermented tofu T1, T3, T4, and T6;

[0112] The transfer of fermented tofu T1, T3, T4, and T6 is accomplished by the third transverse moving section 51, the sixth lifting section 54, and the seventh lifting section 56. Once the fermented tofu T1, T3, T4, and T6 are grabbed, the fifth lifting section 52, the sixth lifting section 54, and the seventh lifting section 56 simultaneously work to lift the fermented tofu to a certain height. The third transverse moving section 51 then moves the entire fermented tofu toward the mouth of the fermented tofu bottle, positioning the center of mass of the combined fermented tofu T1 and T3 directly above the center of the bottle mouth. At this point, the third transverse moving section 51 stops. The fifth lifting section 52 then drives the fifth grabbing section 53 downward, moving the fermented tofu T1 and T3 downward. After the fermented tofu T1 and T3 are stacked, the fermented tofu T4 and T6 are stacked separately.

[0113] Step 3: Pack fermented tofu T1, T3, T4, and T6

[0114] The stacking of fermented tofu T1, T3, T4, and T6 begins with the transfer of fermented tofu into the bottles. After being placed in the bottles, the fifth lifting member 52 continues to move the fermented tofu T1 and T3 downward, stopping when the lower surfaces of the fermented tofu T1 and T3 are 5 mm from the upper surface of the lower layer. The third transverse member 51 then moves the fermented tofu T1 and T3 toward the left inner wall of the fermented tofu bottle, stopping approximately 1.5 mm from the front sidewall. The fifth lifting member 52 then continues downward until the lower surface of the fermented tofu contacts the upper surface of the lower layer. At this point, the fifth lifting member 52 stops, and the clamping and dispensing stepper motor 331 of the fifth gripping member 53 activates, releasing and lifting the outer gripping jaws 3324 of the fermented tofu T1 and T3 until all of the fermented tofu T1 and T3 are removed from the sides and dispensed to the predetermined stacking locations. At this time, the inner clamping claws 3333 of the fermented bean curd T1T3 are still in the fermented bean curd bottle and have not been extracted.

[0115] At this point, fermented tofu T4 and T6 have already been moved to the top of the bottle mouth (not the center) in the previous process step. Due to their spatial relationship, fermented tofu T4 and T6 cannot be bottled at the same time. Since T4 and T6 follow mirror-image process paths, differing only in timing, only T4 will be discussed here.

[0116] Under the action of the horizontal and vertical micro-motion assemblies 543 and 544 of the sixth lifting member 54, the fermented tofu T4 moves toward the center of the bottle's mouth until the fermented tofu and the T4 jaws 553 can be vertically inserted into the bottle (without interfering with the edge of the bottle mouth). At this point, the sixth lifting member 54 is activated, moving the fermented tofu T4 downward until the lower surface of the fermented tofu T4 is 3-5 mm from the upper surface of the underlying fermented tofu layer. At this point, the horizontal micro-motion stepper motor 5431 is reversed, moving the fermented tofu T4 in the opposite direction until the side of the fermented tofu T4 is 1-1.5 mm away from the right side wall of the fermented tofu bottle.

[0117] At this point, the longitudinal micro-motion assembly 544 of the clamping jaws is driven in the reverse direction, and the fermented tofu T4, supported by the two T4 clamping jaws 553 (the clamping force here is provided by the secondary slide return spring 5446), moves away from the center of the bottle mouth until the T4 clamping jaws 553 release. The fermented tofu T4 then moves toward the side of the bottle, closer to the bottle wall. After the fermented tofu T4 is stacked in place, the fermented tofu T6 is stacked.

[0118] Afterward, the bottle-entry paddle 231 on the indexing plate body 1 enters the fermented bean curd bottle, with the bottom of the paddle 231 positioned 3-5 mm from the upper surface of the fermented bean curd layer below and remaining stationary. The sixth and seventh lifting members 54 and 56 are activated, raising the sixth and seventh gripping members 55 and 57 until the gripping jaws return to zero. The process then waits for the next work cycle. The indexing plate body then rotates to the sixth station.

[0119] At the sixth station, the fermented tofu T2 and T5 are grabbed and transported into bottles by the fourth grabbing mechanism and stacked in order and position.
