Description

Technical Field

[0002] Apple is a highly nutritious fruit. When the apples are ripe, fruit manufacturers will purchase them from fruit farmers, and then grade them according to their size, shape and color. Fruits of different grades are then classified, packaged and shipped out of the factory. In this process, after the apples are classified, they need to be transported to the packaging line of their grade using a conveying and loading device, so that the packaging personnel can load the materials. However, when the classified apples are transferred to the conveying device, the existing method is to directly pour apples of the same grade onto the conveying device.

The air bag 2 39 is initially in a state of expansion to the limit, and the apples are supported and fixed by four air bags 2 39 in the same support frame 34, so as to protect the apples. Ventilation channels are provided in the support frame 34 and the fixed seat 1 37. The fixed shell 35 is connected to the ventilation channel in the adjacent support frame 34, and the ventilation channel in the support frame 34 is connected to the ventilation channel in the adjacent fixed seat 1 37. The part of the rotating rod 2 38 located in the adjacent air bag 2 39 is provided with a ventilation hole, and the ventilation channel in the fixed seat 1 37 is connected to the ventilation hole on the adjacent rotating rod 2 38. The support frame 1 is fixedly connected to the collecting frame 310, and a torsion spring is connected between the air bag 2 39 and the adjacent fixed seat 1 37, and this torsion spring is initially in a state of storing force.

[0045] Please refer to Figure 7-Figure 9 As shown, the support frame 34 is slidably connected with an extrusion block 1 41 and an extrusion block 2 42, the extrusion block 1 41 is a triangular block, the extrusion block 2 42 is composed of a square block and a straight rod, the straight rod is rotatably connected to the square block, and a torsion spring is connected between the two, the support frame 34 is rotatably connected with four rotating wheels 43 distributed in a cross, two rotating rods 2 38 symmetrically distributed in the same support frame 34 are fixedly connected and wrapped with a connecting rope 44, the connecting rope 44 passes around the adjacent rotating wheels 43, the square blocks on the extrusion block 1 41 and the extrusion block 2 42 are respectively fixedly connected to the adjacent connecting ropes 44, the support frame 1 is fixedly connected with an extrusion block 3 45 and an extrusion block 4 46, the extrusion block 3 45 is a triangular block, the extrusion block 46 is a square block, the extrusion block 3 45 squeezes the inclined surface on the extrusion block 1 41 through the inclined surface thereon to move the extrusion block 1 41, and the extrusion block 46 squeezes the straight rod on the extrusion block 2 42 to move the extrusion block 2 42.

[0046] When it is necessary to transport apples and inspect their appearance, the staff starts the two electric pulleys 11, the two electric pulleys 14, the visual sensor on the support frame 13, the visual sensor on the support frame 1 and the appearance inspection device 31 through the control terminal, and connects the negative pressure device with the connecting pipe 110. The two electric pulleys 14 work to drive the conveyor belt 15 between them to move circumferentially, and the two electric pulleys 11 work to drive the conveyor belt 12 between them to move circumferentially. Then the staff puts the processed apples on the conveyor belt 15, and the conveyor belt 15 drives the apples to move from left to right. During this process, the conveyor belt 15 on the support frame 13 The visual sensor detects the position of the apple until the apple moves to be flush with the left airbag 22. The visual sensor on the support frame 13 shuts down the two electric pulleys 11 and 14 through the control terminal, and starts the motor 18 on the left. The output shaft of the motor 18 drives the rotating rod 17 through the gear set to drive the parts thereon to rotate. After the rotating rod 17 rotates 180°, the airbag 22 is located on the upper side of the conveyor belt 15. The control terminal shuts down the motor 18 on the left and starts the electric push rod 16 on the left. The telescopic end of the electric push rod 16 drives the adjacent rotating rod 17 to move downward, and the rotating rod 17 drives the parts thereon to move downward synchronously.

[0047] In the process of the rotating rod 17 moving downward, when the air bag 22 moves to contact with the apple, since the shape of the apple is wide at one end and narrow at the other end, the sliding rod 25 on the air bag 22 that first contacts with the apple moves upward and compresses the adjacent spring. After the sliding rod 25 moves upward, the sliding rod 25 blocks the ventilation pipe 23 on the lower side of the adjacent fixed pipe 24, so that the gas in the air storage shell 21 no longer enters the sliding rod 25 through the ventilation pipe 23 on the lower side. At the same time, in the process of the sliding rod 25 moving upward, the sliding rod 25 squeezes the gas in the adjacent fixed pipe 24, so that the gas in the fixed pipe 24 is The gas enters the air storage shell 21 through the upper ventilation pipe 23, and then enters the other sliding rod 25 through the lower ventilation pipe 23. The gas entering the sliding rod 25 enters the adjacent area of ​​the adjacent air bag 22 through the ventilation channel thereon, so that the adjacent area in the air bag 22 expands and deforms and wraps the apple, thereby ensuring that there is no gap between the apple and the air bag 22 when the suction cup 19 adsorbs the apple, avoiding air leakage between the apple and the air bag 22 due to the lack of complete contact between the apple and the air bag 22, which makes the suction cup 19 unable to adsorb the apple.

[0048] After the airbag 22 wraps the apple, the visual sensor on the support frame 13 turns off the electric push rod 16 on the left and starts the negative pressure device. The negative pressure device generates negative pressure and adsorbs the apple through the connecting pipe 110 and the suction cup 19. The apple is transported by adsorption by the suction cup 19, thereby completing the loading operation and protecting the appearance of the apple to prevent the appearance of the apple from being damaged during the transportation process, which would cause the apple's rating to drop.

[0049] After the suction cup 19 absorbs the apple, the control terminal starts the electric push rod 16 on the left, and the telescopic end of the electric push rod 16 drives the adjacent rotating rod 17 to move upward and reset. After the telescopic end of the electric push rod 16 is reset, the control terminal turns off the electric push rod 16 on the left and starts the motor 18 on the left. The output shaft of the motor 18 drives the rotating rod 17 through the gear group to drive the parts on it to rotate in the opposite direction. After the rotating rod 17 rotates 180 degrees in the opposite direction, the control terminal turns off the motor 18 on the left. At this time, the apple is located on the upper side of the conveyor belt 12, and then the control terminal starts the left The electric push rod 16, the telescopic end of the electric push rod 16 drives the adjacent rotating rod 17 to move downward, and the rotating rod 17 drives the parts thereon to move downward synchronously until the apple contacts a support frame 34 on the conveyor belt 12, the control terminal shuts down the electric push rod 16 on the left, and shuts down the negative pressure device, the suction cup 19 no longer absorbs the apple, and then the control terminal starts the electric push rod 16 on the left, the telescopic end of the electric push rod 16 drives the adjacent rotating rod 17 to move upward and reset, after the rotating rod 17 is reset to the initial position, the control terminal shuts down the electric push rod 16 on the left.

[0050] When the apple contacts a support frame 34 on the conveyor belt 12, the control terminal starts the two electric pulleys 11 and the two electric pulleys 2 14, and the conveyor belt 12 drives the apple to move through the support frame 34. During this process, the visual sensor on the support frame 1 detects the position of the apple until the apple moves to be flush with the right airbag 22. The visual sensor on the support frame 1 shuts down the two electric pulleys 11 and the two electric pulleys 2 14 through the control terminal, and starts the motor 18 on the right. The above process is then repeated to transport the apple to the location of the packaging personnel.

[0051] When the apple contacts a support frame 34 on the conveyor belt 12, the apple is located between the four air bags 2 39 on the adjacent support frame 34. As the conveyor belt 12 moves, the support frame 34 drives the apple to move through the four air bags 2 39 thereon until the apple moves to the lower side of the appearance inspection device 31. The appearance inspection device 31 then starts to inspect the appearance of the apple.

[0052] During the movement of the apple at the lower side of the appearance inspection device 31, when the extrusion block three 45 contacts the extrusion block one 41 on the support frame 34, under the extrusion action of the extrusion block three 45, the extrusion block one 41 drives the adjacent connecting rope 44 to move, so that the front and rear two rotating rods two 38 drive the adjacent airbags two 39 to rotate, and the front airbag two 39 rotates counterclockwise (from the perspective of the left view) and continues to tighten the adjacent torsion springs. The rear airbag two 39 rotates counterclockwise under the action of the adjacent torsion springs, and the airbag two 39 rotates the apple through friction transmission, so that the lower side of the apple rotates to the upper side (this lower side specifically refers to the surface of the apple located at the lower side of the four airbags two 39), which facilitates the appearance inspection device 31 to fully inspect the appearance of the apple.

[0053] After the extrusion block three 45 is no longer in contact with the extrusion block one 41 on the support frame 34, under the action of the torsion spring between the front airbag two 39 and the fixing seat one 37, the front and rear airbags two 39 rotate to drive the apple to reset, and at the same time, the torsion spring adjacent to the rear airbag two 39 twists and accumulates force.

[0054] After the front and rear airbags 239 rotate and reset, the extrusion block 46 contacts the straight rod on the extrusion block 232 on the support frame 34, and then under the extrusion action of the extrusion block 46, the extrusion block 232 drives the adjacent connecting rope 44 to move (at this time, the straight rod does not rotate, and the torsion spring between the straight rod and the square block does not store force), so that the left and right rotating rods 238 drive the adjacent airbags 239 to rotate, and the airbag 239 on the right rotates clockwise (from the perspective of the main view) and continues to tighten the adjacent torsion spring. The airbag 239 on the left rotates clockwise under the action of the adjacent torsion spring, and the airbag 239 transmits the apple through friction. Rotate until the extrusion block 2 42 is limited by the support frame 34, the straight rod on the extrusion block 2 42 starts to rotate, and the torsion spring adjacent to the straight rod starts to accumulate force until the straight rod on the extrusion block 2 42 rotates 90°, and the extrusion block 2 42 can pass through the adjacent extrusion block 4 46. After the extrusion block 2 42 passes through the adjacent extrusion block 4 46, under the action of the torsion spring between the straight rod and the adjacent square block, the straight rod rotates and resets. At the same time, under the action of the torsion spring between the right airbag 2 39 and the fixing seat 1 37, the left and right airbags 2 39 rotate to drive the apple to reset, and at the same time, the torsion spring adjacent to the left airbag 2 39 twists and accumulates force.

[0055] When the appearance inspection device 31 inspects the appearance of the apple, the conveyor belt 12 continues to move until the slide bar 36 moves to the rear side of the electromagnetic adsorption plate 33. At this time, the electric push rod 2 32 determines whether to work based on the inspection result of the appearance inspection device 31 on the appearance of the apple on the support frame 34. If there is no problem with the appearance of the apple, the electric push rod 2 32 does not work. If there is a problem with the appearance of the apple, the appearance inspection device 31 shuts down the two electric pulleys 11 and the two electric pulleys 2 14 through the control terminal, and starts the electric push rod 2 32 and the electromagnetic adsorption plate 33.

[0056] When the electric push rod 32 is working, the telescopic end of the electric push rod 32 drives the electromagnetic adsorption plate 33 to move backward. When the electromagnetic adsorption plate 33 moves to contact with the slide bar 36, the control terminal controls the telescopic end of the electric push rod 32 to move forward. The telescopic end of the electric push rod 32 drives the electromagnetic adsorption plate 33 to start moving forward. At this time, under the magnetic attraction of the electromagnetic adsorption plate 33, the slide bar 36 moves forward to compress the adjacent spring and generate negative pressure in the adjacent fixed shell 35. Subsequently, under the action of the negative pressure, the gas in the airbag 39 passes through the adjacent rotating rod 36. The ventilation holes on 8 and the ventilation channels in the adjacent fixing seat 1 37 and the adjacent supporting frame 34 enter the adjacent fixed shell 35. At this time, due to the reduction of gas in the air bag 2 39, the air bag 2 39 begins to deflate and reduce the support for the apple until the electric push rod 2 32 moves forward to the reset state, and the air bag 2 39 no longer supports the adjacent apples. Then, under the action of gravity, the apples fall into the collection rack 310, and then the control terminal starts the two electric pulleys 11 and the two electric pulleys 2 14, and shuts down the electric push rod 2 32 and the electromagnetic adsorption plate 33.

[0057] After the electromagnetic adsorption plate 33 stops working, under the action of the spring between the slide bar 2 36 and the fixed shell 35, the slide bar 2 36 is reset, and the gas in the adjacent fixed shell 35 is transported back to the adjacent airbag 2 39 through the ventilation channels in the adjacent support frame 34 and the adjacent fixed seat 1 37 and the ventilation holes on the adjacent rotating rod 2 38, so that the airbag 2 39 is inflated and reset.

[0059] Please refer to Figure 6 , Figure 7 and Fig.12 As shown, an electric push rod 4 61 is installed at the lower part of the support frame 1, and the electric push rod 4 61 is electrically connected to the control terminal. The telescopic end of the electric push rod 4 61 is fixedly connected with an extrusion block 5 62 and an extrusion block 63. The extrusion block 5 62 is set as a triangular block whose shape and size are consistent with the extrusion block 3 45, and the extrusion block 6 63 is set as a square block whose shape and size are consistent with the extrusion block 4 46. The extrusion block 1 41 is extruded and matched with the extrusion block 5 62, and the extrusion block 2 42 is extruded and matched with the extrusion block 6 63.

[0060] Please refer to Fig.13 and Fig.14As shown, the part of the rotating rod 2 38 located in the adjacent airbag 2 39 is rotatably connected to the fixed seat 2 71, the fixed seat 2 71 is fixedly connected to the adjacent fixed seat 1 37, and is rotatably connected to the adjacent airbag 2 39, a slide plate 72 is slidably connected in the fixed seat 2 71, a spring is connected between the slide plate 72 and the adjacent fixed seat 2 71, the slide plate 72 is provided with a convex column, the slide plate 72 is spline-connected with an arc plate 73, the arc plate 73 consists of two rods and an arc plate, an inclined groove is provided in the fixed seat 2 71, the convex column on the slide plate 72 is located in the inclined groove in the adjacent fixed seat 2 71 and slides, in the same support frame 34, four arc plates 73 are respectively located on the outside of the adjacent airbag 2 39, the support frame 1 is installed with an electric push rod 5 74 electrically connected to the control terminal, the telescopic end of the electric push rod 5 74 is installed with a push plate 75, and the slide rod 2 36 is squeezed and matched with the push plate 75.

[0061] When the staff connects the negative pressure device with the connecting pipe 110 , the staff connects the liquid inlet pipe 54 with the liquid supply device.

[0062] During the circumferential movement of the conveyor belt 12, when the visual sensor on the support frame 1 detects that the first support frame 34 for placing apples moves to the upper side of the electric push rod 3 51, the visual sensor on the support frame 1 starts the electric push rod 3 51 through the control terminal, and shuts down the two electric pulleys 1 11 and the two electric pulleys 2 14. The telescopic end of the electric push rod 3 51 drives the fixed tube 2 52 and the parts thereon to move upward synchronously until the four nozzles 53 are in contact with the air bag 2 39. The control terminal shuts down the electric push rod 3 51, and then starts the liquid supply device. The liquid supply device transports cleaning liquid to the fixed tube 2 52 through the liquid inlet pipe 54. The cleaning liquid entering the fixed tube 2 52 is sprayed out through the four nozzles 53 to clean the air bag 2 39, so as to prevent the fruit liquid produced by the apples from being deteriorated and rotted from adhering to other apples through the air bag 2 39 during the process of the four air bags 2 39 supporting the apples, so that the other apples that come into contact with the fruit liquid adhering to the air bag 2 39 also deteriorate and rot.

[0063] During the process of the four nozzles 53 spraying cleaning liquid, the control terminal starts the electric push rod four 61, and the telescopic end of the electric push rod four 61 drives the extrusion block five 62 and the extrusion block six 63 to move to the right. The extrusion block five 62 moves to the right and repeats the process of the extrusion block three 45 and the extrusion block one 41 to make the two adjacent airbags two 39 rotate. The extrusion block six 63 moves to the right and repeats the process of the extrusion block two 42 and the extrusion block four 46 to make the two adjacent airbags two 39 rotate as well. This makes it easier for the nozzle 53 to comprehensively clean the airbag two 39.

[0064] When the control terminal starts the liquid supply device, the control terminal starts the electric push rod 5 74, and the telescopic end of the electric push rod 5 74 drives the push plate 75 to move backward. When the push plate 75 moves to contact the slide bar 2 36, the push plate 75 drives the slide bar 2 36 to move backward. The slide bar 2 36 moves backward to stretch the adjacent spring, and the gas in the adjacent fixed shell 35 is transported to the adjacent air bag 2 39 through the ventilation channel in the adjacent support frame 34, the ventilation channel in the adjacent fixed seat 1 37 and the ventilation hole on the adjacent rotating rod 2 38. The air bag 2 39 expands to the limit state. Therefore, the gas entering the air bag 2 39 will act on the adjacent slide plate 72, causing the slide plate 72 to move in the direction close to the adjacent fixed seat 1 37 and compress the adjacent spring. In the process of the movement of the slide plate 72 The convex column on the slide plate 72 moves along the inclined groove in the adjacent fixing seat 2 71, so that the slide plate 72 drives the adjacent arc plate 73 to rotate until the telescopic end of the electric push rod 5 74 is fully extended. At this time, the control terminal shuts down the electric push rod 5 74, the slide plate 72 no longer moves, and the arc plate 73 rotates to the lower side of the arc plate located in the airbag 2 39, thereby supporting the part of the airbag 2 39 flushed by the adjacent nozzle 53, preventing the part of the airbag 2 39 flushed from being deformed by the impact of the sprayed cleaning liquid during the process of the airbag 2 39 being flushed by the adjacent nozzle 53, resulting in the fruit liquid adhering to the surface of the airbag 2 39 being hidden in the dead angle area after its deformation, so that the cleaning liquid sprayed by the nozzle 53 cannot clean the fruit liquid adhering to the airbag 2 39.

[0065] After the nozzle 53 has finished cleaning the airbag 2 39, the control terminal shuts down the liquid supply device and the electric push rod 4 61, and starts the electric push rod 5 74. The telescopic end of the electric push rod 5 74 drives the push plate 75 to move forward and reset. The push plate 75 moves forward to reduce the squeezing of the slide bar 2 36. At this time, under the action of the adjacent spring, the slide bar 2 36 moves forward and resets, and extracts the gas in the adjacent airbag 2 39 through the ventilation channel in the adjacent support frame 34, the ventilation channel in the adjacent fixing seat 1 37 and the ventilation hole on the adjacent rotating rod 2 38. At this time, as the gas in the airbag 2 39 is reduced, Under the action of the spring between the slide plate 72 and the adjacent fixing seat 2 71, the slide plate 72 moves and resets in the direction away from the adjacent fixing seat 1 37. During the reset process of the slide plate 72, the convex column on the slide plate 72 moves along the inclined groove in the adjacent fixing seat 2 71, so that the slide plate 72 drives the adjacent arc plate 73 to rotate in the opposite direction and reset. Until the telescopic end of the electric push rod 5 74 is completely reset, the control terminal shuts down the electric push rod 5 74. At this time, the slide plate 72 and the arc plate 73 are also reset to the initial state, and then the control terminal starts the two electric pulleys 11 and the two electric pulleys 2 14.

[0066] When the control terminal starts the two electric pulleys 11 and the two electric pulleys 2 14, the control terminal starts the electric push rod 4 61, and the telescopic end of the electric push rod 4 61 is reset. After the telescopic end of the electric push rod 4 61 is reset, the control terminal shuts down the electric push rod 4 61 until the next support frame 34 moves to the upper side of the electric push rod 3 51, and repeats the above steps.

[0067] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
