Description

Technical Field

[0001] The invention relates to the technical field of pickle packaging container transportation, in particular to container transportation equipment and method for finished pickle packaging. Background Art

[0002] Pickles are made from fresh vegetables, which are pickled with salt to make pickle blanks. The excess brine in the pickle blanks is then squeezed or soaked in clean water to reduce the salinity, thereby reducing the salinity of the finished vegetable blanks. Different pastes or soy sauces are then used to make the pickles, so that the sugars, amino acids and aromas in the pastes can penetrate into the pickle blanks, making them delicious, nutritious, appetizing and easy to preserve. After the pickles are processed, they are stored in containers and then packaged in corrugated cardboard boxes. Conveying equipment and stackers are used to stack the boxed pickles on wooden or plastic pallets on warehouse shelves for easy storage of the finished pickles.

[0003] When transporting packaged finished pickles, the existing stacker conveying equipment only lifts the pallet with the packaged finished pickles by a structure similar to the front shovel of a forklift, and places the boxes of finished pickles on the shelves by moving the track and rising the lifting mechanism. There is a lack of protection structure for the finished pickles, especially when the conveying equipment stacker starts and stops, the pickles will shake or even slide relatively on the pallet due to inertia, affecting the stability of the pickles during transportation, resulting in the risk of the pickles falling during transportation, reducing the safety of the pickles during transportation and stacking. At the same time, after the pickles are placed on the shelves, the displacement between the pickles and the pallet caused by shaking will also cause a greater risk for the next time the pickles are taken, thereby causing certain safety issues when the conveying equipment stacker transports the finished pickles.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing container conveying equipment for finished pickle packaging, and even if it can be solved, it needs to be solved through the cooperation of external tools, which makes it impossible to achieve the desired effect.

[0015] A conveying method of a container conveying device for finished pickle packaging, specifically comprising the following steps: S1: First, connect the external power supply and controller to the bidirectional motor. When the packaged finished pickles need to be transported and stacked, first place the finished pickles packaged in corrugated paper on the pallet. Then, the bidirectional motor cooperates with the speed reducer, the pulley and the first V-belt to drive the first screw to rotate inside the sliding frame, so that the sliding block drives the pallet to slide forward and insert into the gap under the pallet. At this time, the finished pickles on the pallet can be lifted up by cooperating with the lifting machine. Then, the bidirectional motor reverses and moves the pallet to the top of the support frame through the pallet. S2: The other output end of the bidirectional motor drives the connecting rod and the worm to rotate through the meshing relationship between the first bevel gear and the first connecting shaft through the second bevel gear. When the worm rotates, it can cooperate with the worm wheel to drive the second screw to rotate, and then cooperate with the sliding rod to limit the moving frame. The second screw can drive the baffle plate and the rubber plate to move to the left through the moving frame, and approach the finished pickles above the supporting frame from the left. At this time, the limiting frame can prevent the finished pickles from excessive shaking and relative sliding from the rear and right sides. S3: When the second screw rotates, the fourth bevel gear cooperates with the auxiliary frame to limit the second connecting shaft, and the third connecting shaft can be driven to rotate by the second connecting shaft. When the third connecting shaft rotates, it can cooperate with the third bevel gear to drive the third screw to rotate inside the connecting seat, so that the moving block can drive the first movable frame on the right to slide to the left, and then cooperate with the second movable frame on the right and the auxiliary block to slide to the left in the moving seat, so that the scissor-type telescopic frame can be expanded upward with the assistance of the telescopic cylinder, so as to limit the finished pickles on the pallet from the front. S4: When the pallet moves to the top of the support frame, the bidirectional motor can drive the internal rotor of the air pump to rotate through the second V-belt, so that the air pump can inhale the outside air through the air intake cover and the air intake slot, and send it into the rubber airbag through the air supply pipe. At this time, with the expansion of the rubber airbag and the elastic force of the auxiliary spring, the position of the finished pickles on the pallet can be limited, and the limit frame can be prevented from scratching the outer packaging of the finished pickles. In addition, when the scissor-type telescopic frame is unfolded upward, the moving seat can be used to unfold the rubber air curtain, and then part of the gas in the air supply pipe can be sent into the rubber air curtain through the shunt pipe to expand it, thereby preventing the scissor-type telescopic frame and the connecting seat from scratching the outer packaging of the finished pickles, so that the finished pickles packaged in corrugated paper are not easily crushed or scratched by the metal parts on the conveying equipment stacker; S5: When the pallet moves to the top of the support frame, the rubber airbag and the rubber air curtain have been inflated, so the protection effect of the finished pickle outer packaging can be prevented from being affected by the untimely inflation of the rubber airbag and the rubber air curtain. Finally, the first pressure relief valve and the second pressure relief valve can be used to discharge the excess gas in the rubber airbag and the rubber air curtain to prevent the rubber airbag and the rubber air curtain from over-expanding and squeezing the finished pickle outer packaging. In addition, the good elasticity of the rubber air curtain itself and the second pressure relief valve can be used to make the rubber air curtain expand without affecting the smooth deployment of the scissor-type telescopic frame. When the finished pickles are moved to the shelf placement position through the movement of the elevator and the bottom guide rail, and the limit movement of the top guide rail, it is only necessary to let the bidirectional motor rotate again to move the baffle to the right, and the scissor-type telescopic frame shrinks, and finally the sliding block drives the pallet and the pallet to move to the top of the shelf, and the pallet is placed on the shelf to complete the transportation and stacking of the finished pickles.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is provided with a conveying protection unit, which can move the pallet with the finished pickles placed on it to the support frame for transportation, and can prevent the finished pickles from excessive shaking and relative sliding from the rear and right side, thereby increasing the transportation stability of the packaged finished pickles, so that the finished pickle packaging container transportation equipment can transport the finished pickles more stably and reliably, and the finished pickles are not easy to fall due to sliding during transportation, thereby increasing the safety of pickles during transportation and stacking.

[0017] 2. The present invention provides a conveying limit unit, which can limit the finished pickles on the pallet from the front without affecting the smooth movement of the finished pickles to the support plate, so that the inertia generated when the conveying equipment stacker starts and stops will not cause the finished pickles to shake excessively and slide relatively on the pallet, so that the finished pickles can maintain a neat and stable display structure after being placed on the shelf, reducing the safety hazard in the next pickle retrieval process, and further improving the transportation safety of the conveying equipment stacker.

[0018] 3. The present invention can cooperate with the conveying protection unit and the conveying limit unit by setting a protection mechanism to further protect the packaged finished pickles, so that the finished pickles packaged in corrugated paper are not easily crushed or scratched by the metal parts on the conveying equipment stacker, thereby ensuring the integrity of the corrugated paper outer packaging of the finished pickles, so that the corrugated paper outer packaging of the finished pickles can also be well protected during transportation.

[0028] As a further limitation of the protection mechanism 3 of the present invention, the protection mechanism 3 includes a rubber airbag 301, the back of the rubber airbag 301 is fixedly connected to the front of the limit frame 2102, the upper surface of the rubber airbag 301 is fixedly connected to the first pressure relief valve 302, the inner side wall of the limit frame 2102 is fixedly connected to three auxiliary springs 303, the outer surface of each auxiliary spring 303 is in contact with the back of the rubber airbag 301, the opposite sides of the connecting seat 2202 and the movable seat 2203 are commonly fixedly connected to a rubber air curtain 304, the upper surface of the rubber air curtain 304 is fixedly connected to the second pressure relief valve 305, the bottom surface of the support frame 2101 is fixedly connected to the air pump 306, the outer surface of the input end of the reducer 2109 is sleeved with a second V-belt 307, The inner wall of the second triangular belt 307 is in contact with the outer surface of the input end of the air pump 306, and the air outlet end of the air pump 306 is fixedly connected with an air pipe 308, and the other end of the air pipe 308 is fixedly connected with the inner cavity of the rubber airbag 301, and the outer surface of the air pipe 308 is fixedly connected with a shunt pipe 309, and the shunt pipe 309 is fixedly connected with the inner cavity of the rubber air curtain 304. By setting the protection mechanism 3, the conveying protection unit 21 and the conveying limit unit 22 can be coordinated to further protect the packaged finished pickles, so that the finished pickles packaged in corrugated paper are not easily crushed or scratched by the metal parts on the conveying equipment stacker, thereby ensuring the integrity of the corrugated paper outer packaging of the finished pickles, so that the corrugated paper outer packaging of the finished pickles can also be well protected during transportation; The air inlet end of the air pump 306 is fixedly connected to an air inlet hood 310, the upper surface of the air inlet hood 310 is fixedly connected to the bottom surface of the support frame 2101, and the outer surface of the air inlet hood 310 is provided with a plurality of air inlet grooves 311. The air inlet hood 310 and the air inlet grooves 311 can prevent external impurities from entering the air pump 306, thereby realizing simple filtration of the air and reducing the impact of impurities on the air pump 306.

[0029] The specific implementation of this embodiment is as follows: when the pallet 2108 moves to the top of the support frame 2101, the bidirectional motor 2103 can drive the internal rotor of the air pump 306 to rotate through the second V-belt 307, so that the air pump 306 can inhale the outside air through the air inlet cover 310 and the air inlet groove 311, and send it into the rubber airbag 301 through the air supply pipe 308. At this time, with the expansion of the rubber airbag 301 and the elastic force of the auxiliary spring 303, the position of the finished pickles on the pallet 2108 can be limited, and the limit frame 2102 can be prevented from scratching the finished pickles. Moreover, when the scissor-type telescopic frame 2205 is unfolded upward, the rubber air curtain 304 can be unfolded in cooperation with the movable seat 2203, and then part of the gas in the air delivery pipe 308 can also be sent into the rubber air curtain 304 through the shunt pipe 309 to expand it, thereby preventing the scissor-type telescopic frame 2205 and the connecting seat 2202 from scratching the finished pickle outer packaging, making it difficult for the finished pickles packaged in corrugated paper to be crushed or scratched by the metal parts on the conveying equipment stacker, thereby ensuring the integrity of the corrugated paper outer packaging of the finished pickles, so that the corrugated paper outer packaging of the finished pickles can also be obtained during transportation. At the same time, when the pallet 2108 moves to the top of the support frame 2101, the rubber airbag 301 and the rubber air curtain 304 have been inflated, so the protection effect of the finished pickle outer packaging can be prevented from being affected by the untimely inflation of the rubber airbag 301 and the rubber air curtain 304. Finally, the first pressure relief valve 302 and the second pressure relief valve 305 can be used to discharge the excess gas in the rubber airbag 301 and the rubber air curtain 304 to prevent the rubber airbag 301 and the rubber air curtain 304 from over-expanding and squeezing the finished pickle outer packaging. In addition, the rubber air curtain 304 itself can be used to prevent the outer packaging of the finished pickles from being squeezed. The good elasticity and the second pressure relief valve 305 ensure that the expansion of the rubber air curtain 304 will not affect the smooth deployment of the scissor-type telescopic frame 2205. When the finished pickles are moved to the shelf placement position through the movement of the elevator 15 and the bottom guide rail 11, and the limit movement of the top guide rail 13, it is only necessary to let the bidirectional motor 2103 rotate again to let the baffle 2113 move to the right, and the scissor-type telescopic frame 2205 shrink, and finally let the sliding block 2106 drive the support plate 2107 and the pallet 2108 to move to the top of the shelf, and place the pallet 2108 on the shelf to complete the transportation and stacking of the finished pickles.

[0030] A conveying method of a container conveying device for finished pickle packaging, specifically comprising the following steps: S1: First, connect the external power supply and controller to the bidirectional motor 2103. When the packaged finished pickles need to be transported and stacked, first place the finished pickles packaged in corrugated paper on the pallet 2108. Then, the bidirectional motor 2103 cooperates with the deceleration of the reducer 2109 and the pulley 2110 and the first V-belt 2111 to drive the first screw 2105 to rotate inside the sliding frame 2104, so that the sliding block 2106 drives the support plate 2107 to slide forward and insert into the gap under the pallet 2108. At this time, the finished pickles on the pallet 2108 can be lifted up by cooperating with the lifting machine 15 to rise upward. Then, the bidirectional motor 2103 is reversed, and the pallet 2108 is moved to the top of the support frame 2101 through the support plate 2107. S2: The other output end of the bidirectional motor 2103 drives the connecting rod 2117 and the worm 2119 to rotate through the meshing relationship between the first bevel gear 2115 and the first connecting shaft 2116 through the second bevel gear 2118. When the worm 2119 rotates, it can cooperate with the worm wheel 2121 to drive the second screw 2120 to rotate, and then cooperate with the sliding rod 2124 to limit the movable frame 2112. The second screw 2120 can drive the baffle 2113 and the rubber plate 2114 to move to the left through the movable frame 2112, and approach the finished pickles above the support frame 2101 from the left. At this time, the limiting frame 2102 can prevent the finished pickles from excessive shaking and relative sliding from the rear and right sides; S3: When the second screw rod 2120 rotates, the fourth bevel gear 2210 cooperates with the auxiliary frame 2211 to limit the second connecting shaft 2212, and the third connecting shaft 2213 can be driven to rotate through the second connecting shaft 2212. When the third connecting shaft 2213 rotates, it can cooperate with the third bevel gear 2209 to drive the third screw rod 2207 to rotate inside the connecting seat 2202, so that the moving block 2208 can drive the first movable frame 2204 on the right to slide to the left, and then cooperate with the second movable frame 2206 on the right and the auxiliary block 2215 to slide to the left in the moving seat 2203, so that the scissor-type telescopic frame 2205 can be expanded upward with the assistance of the telescopic cylinder 2214, so as to limit the finished pickles on the pallet 2108 from the front. S4: When the pallet 2108 moves to the top of the support frame 2101, the bidirectional motor 2103 can drive the internal rotor of the air pump 306 to rotate through the second V-belt 307, so that the air pump 306 can inhale the outside air through the air intake cover 310 and the air intake slot 311, and send it into the rubber airbag 301 through the air supply pipe 308. At this time, with the expansion of the rubber airbag 301 and the elastic force of the auxiliary spring 303, the position of the finished pickles on the pallet 2108 can be limited, and It can prevent the limit frame 2102 from scratching the outer packaging of the finished pickles, and when the scissor-type telescopic frame 2205 is unfolded upward, it cooperates with the movable seat 2203 to unfold the rubber air curtain 304, and then part of the gas in the air supply pipe 308 can also be sent into the rubber air curtain 304 through the shunt pipe 309 to expand it, thereby preventing the scissor-type telescopic frame 2205 and the connecting seat 2202 from scratching the outer packaging of the finished pickles, so that the finished pickles packaged in corrugated paper are not easily crushed or scratched by the metal parts on the conveying equipment stacker; S5: When the pallet 2108 moves to the top of the support frame 2101, the rubber airbag 301 and the rubber air curtain 304 have been inflated, so the protection effect of the finished pickle outer packaging can be prevented from being affected by the untimely inflation of the rubber airbag 301 and the rubber air curtain 304. Finally, the first pressure relief valve 302 and the second pressure relief valve 305 can be used to discharge the excess gas in the rubber airbag 301 and the rubber air curtain 304 to prevent the rubber airbag 301 and the rubber air curtain 304 from over-expanding and squeezing the finished pickle outer packaging. In addition, the good elasticity of the rubber air curtain 304 can be used to prevent the rubber airbag 301 and the rubber air curtain 304 from over-expanding and squeezing the finished pickle outer packaging. The rubber air curtain 304 and the second pressure relief valve 305 can expand without affecting the smooth deployment of the scissor-type telescopic frame 2205. When the finished pickles are moved to the shelf placement position through the movement of the elevator 15 and the bottom guide rail 11, and the limit movement of the top guide rail 13, the bidirectional motor 2103 only needs to rotate again to let the baffle 2113 move to the right, and the scissor-type telescopic frame 2205 shrinks, and finally the sliding block 2106 drives the support plate 2107 and the pallet 2108 to move to the top of the shelf, and the pallet 2108 is placed on the shelf to complete the transportation and stacking of the finished pickles.
