[0044] The following combines specific embodiments to further elaborate on the content of the present utility model in detail:

[0045] In the description of the utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the utility model.

[0046] As Figures 1-3 shown, a feeding device for a multi-bin that can correct the front and back of a product includes a positioning platform mechanism 40 and an intermediate transfer mechanism 30, and also includes a feeding mechanism 10, a transfer and flipping mechanism 20, and a discharging transfer mechanism 50: In this embodiment, the product 60 to be fed is as Figure 8 shown, which are two paper trays of different sizes. There are four grooves 61 on the smaller paper tray and six grooves 61 on the larger paper tray. Figure 8 The state of the paper tray shown is with the front side facing up. Conversely, if the groove 61 protrudes upward, it is with the back side facing up. In this embodiment, the front, rear, left, right, upper, and lower are all with Figure 1 the structure as the reference direction.

[0047] As Figure 3 and Figure 4 shown, the feeding mechanism 10 includes at least two bin units; there is a feeding station corresponding to it, and the product in the bin unit is transferred to the feeding station; the transfer and flipping mechanism 20 is used to determine whether the product on the feeding station is facing up or down, transfer the product facing up to the positioning platform mechanism 40, or flip the product facing down to face up and then transfer it to the intermediate transfer mechanism 30; the intermediate transfer mechanism 30 transfers the product transferred by the transfer and flipping mechanism 20 to the positioning platform mechanism 40; the discharging transfer mechanism 50 transfers the product on the positioning platform mechanism 40 to the next station.

[0048] One bin unit for feeding is the target bin unit. The feeding mechanism 10 includes a first driving component for driving the target bin unit to move directly below the feeding station, a second driving component for driving the product in the target bin unit to rise to the feeding station, and a first detecting component for detecting whether the product at the topmost of the target bin unit has moved to the feeding station. The number of bin units is two, and the two bin units are arranged in a straight line. Taking Figure 1 as the reference, from left to right are the first bin unit 11 and the second bin unit 12 respectively. The first driving component drives the two bin units as a whole to move in a direction perpendicular to the first direction (i.e., along Figure 1In the X direction, the silo unit includes a plurality of vertically arranged enclosing plates 13; the first driving assembly is installed on the fixing plate 14; the first driving assembly includes a first mounting plate 15, a second mounting plate 16, and a first driving member. The first mounting plate 15 is located above the second mounting plate 16. Two silo units are mounted on the top surface of the first mounting plate 15. The second mounting plate 16 is installed on the top surface of the fixing plate 14 through a linear guide. The first driving member is installed on the bottom surface of the fixing plate 14, and the second mounting plate 16 is fixed on the movable part of the first driving member; the second driving assembly includes a support plate 19 and a second driving member for driving the support plate 19 to lift. A notch 17 for avoiding the support plate 19 is formed on the side edge of the first mounting plate 15; the first detecting member is a photoelectric sensor 111, which is arranged on the side of the feeding station. In this embodiment, the first driving member is a first air cylinder 18, and the second driving member is a first electric cylinder 110.

[0049] The working principle of the loading mechanism 10 is as follows: In the initial state, both the first bin unit 11 and the second bin unit 12 are full. The second bin unit 12 is located directly below the feeding station. The pallet 19 is located at the bottom of the products in the second bin, supporting all the products. The piston rod of the first cylinder 18 is in the retracted state. When starting to operate, the first electric cylinder 110 drives the pallet 19 to rise, and then drives all the products in the second bin unit 12 to rise. When the photoelectric sensor 111 detects that the topmost product in the second bin unit 12 has risen to the feeding station, the first electric cylinder 110 stops operating. The transplanting and flipping mechanism 20 picks up the product at the feeding station. The first electric cylinder 110 continues to drive the pallet 19 and the products to rise. When the photoelectric sensor 111 detects that the topmost product in the second bin unit 12 has risen to the feeding station, the first electric cylinder 110 stops operating. The transplanting and flipping mechanism 20 picks up the product at the feeding station, and the feeding is cycled in this way. When the products in the second bin unit 12 are taken out completely, the first electric cylinder 110 drives the pallet 19 to descend to the lowest position (at this time, the pallet 19 is located between the first mounting plate 15 and the second mounting plate 16). The piston rod of the first cylinder 18 extends, driving the second mounting plate 16 to move to the right, and then driving the first bin unit 11 and the second bin unit 12 to move to the right as a whole, so that the first bin unit 11 is located directly below the feeding station. The first electric cylinder 110 drives the pallet 19 to rise through the notch 17 and then supports the bottom of all the products in the first bin unit 11. When the photoelectric sensor 111 detects that the topmost product in the first bin unit 11 has risen to the feeding station, the first electric cylinder 110 stops operating. The transplanting and flipping mechanism 20 picks up the product at the feeding station. The first bin unit 11 feeds materials in the same principle as the second bin unit 12, and at the same time, the second bin unit 12 is refilled manually. When the products in the first bin unit 11 are taken out completely, the first electric cylinder 110 drives the pallet 19 to descend to the lowest position (at this time, the pallet 19 is located between the first mounting plate 15 and the second mounting plate 16). The piston rod of the first cylinder 18 retracts, driving the second mounting plate 16 to move to the left, and then driving the first bin unit 11 and the second bin unit 12 to move to the left as a whole, so that the second bin unit 12 is located directly below the feeding station. The first electric cylinder 110 drives the pallet 19 to rise through the notch 17 and then supports the bottom of all the products in the second bin unit 12, returning to the initial state. It should be noted that the number of bin units can also be three, four or more, and those skilled in the art can easily implement it.

[0050] Such as Figure 6As shown, the transplanting and flipping mechanism 20 includes a second detection member for detecting whether the product on the feeding station is face up or face down, a first grasping assembly, and a third driving assembly for driving the first grasping assembly to reciprocate in a first direction; the first grasping assembly includes a first suction cup module, a flipping driving member for driving the first suction cup module to flip 180°, and a sixth driving assembly for driving the whole flipping driving member to move up and down. In this embodiment, the flipping driving member is a flipping cylinder 29, the sixth driving assembly is a second cylinder 210, and the third driving assembly is a second electric cylinder 211.

[0051] As Figure 7 shown, the first suction cup module includes a slat 21, a plurality of adapter plates 22 vertically fixed on the slat 21 and arranged parallel to each other, and a suction cup module movably mounted on the adapter plates 22; each adapter plate 22 is provided with a mounting groove 23 along its length direction; the suction cup module includes a hollow connecting rod 24, a sleeve 25, a spring 26, and a suction nozzle 27. One end of the connecting rod 24 passes through the mounting groove 23 and is fixedly installed with a mounting nut 28, and the other end is fixedly installed with the suction nozzle 27. The sleeve 25 and the spring 26 are slidably sleeved on the connecting rod 24. The adapter plate 22 is stuck between the mounting nut 28 and the sleeve 25, and the sleeve 25 abuts against the lower end surface of the adapter plate 22 under the action of the spring 26. In the suction cup module of this embodiment, since the sleeve 25 and the spring 26 are slidably sleeved on the connecting rod 24 and the connecting rod 24 passes through the mounting groove 23, that is, the connecting rod 24 can move in the mounting groove 23. When the suction nozzle 27 contacts the product, the spring 26 is further compressed, and the connecting rod 24 drives the suction cup to rise relative to the adapter plate 22, so as to have a buffering effect on the suction cup and avoid sucking the product too tightly by the suction cup.

[0052] The second detection member is a height sensor (not shown in the figure); the height sensor is installed on the slat 21 of the first grasping assembly. The working principle of the height sensor is: the height sensor is fixed on the slat 21 of the first grasping assembly, directly above the groove 61 of the product, and is used to detect the vertical distance between the height sensor and the product on the feeding station. If the product is face up, the groove 61 of the product protrudes downward, and the vertical distance detected by the height sensor is longer. If the product is face down, the groove 61 of the product protrudes upward, and the vertical distance detected by the height sensor is shorter, so as to determine whether the product on the feeding station is face up or face down. Specifically, when the detected vertical distance between the height sensor and the product on the feeding station is lower than the set value of the height sensor, a signal is output to the PLC, and the product is flipped; when the detected vertical distance between the height sensor and the product on the feeding station is higher than the set value of the height sensor, no signal is output to the PLC, and the product is not flipped.

[0053] As Figure 10As shown, the blanking and transplanting mechanism 50 includes a second grasping component and a fourth driving component for driving the second grasping component to reciprocate in the second direction. In this embodiment, the fourth driving component is a third electric cylinder 53; the first direction is parallel to the second direction, and the first direction and the second direction are the Figure 1 Y direction in Figure 8 . In this embodiment, the route for the product to be sent to the trimming machine is basically a straight line along the Y direction, making the feeding device structure of the multi-bin for correcting the front and back of the product more compact and the transportation efficiency of the product higher. The second grasping component includes a second suction cup module 51 and a seventh driving component for driving the overall lifting of the second suction cup module 51. In this embodiment, the seventh driving component is a fourth cylinder 52. The structure of the second suction cup module 51 is the same as that of the first suction cup module, which will not be elaborated here; the intermediate transplanting mechanism 30 is located directly above the positioning platform mechanism 40, as Figure 9 shown. The intermediate transplanting mechanism 30 includes a third grasping component and a fifth driving component for driving the overall lifting of the third grasping component; the third grasping component includes a third suction cup module 31, and the structure of the third suction cup module 31 is the same as that of the first suction cup module, which will not be elaborated here; in this embodiment, the fifth driving component is a fifth cylinder 32. As

[0054] shown, the positioning platform mechanism 40 includes a positioning platform 41, a plurality of push plate components arranged on the positioning platform 41, and baffles 42 corresponding to the plurality of push plate components respectively; in this embodiment, the push plate component includes a push plate 43 and a push plate cylinder 44 for driving the movement of the push plate 43.

[0055] The feeding mechanism 10 continuously feeds materials. When the photoelectric sensor 111 detects that there is a product at the feeding station, the second electric cylinder 211 drives the second cylinder 210 and the first suction cup module to move integrally to directly above the feeding station. The piston rod of the second cylinder 210 extends, and the first suction cup module sucks the product at the feeding station. The height sensor detects whether the product is face up or face down. If the product is face up, the piston rod of the second cylinder 210 retracts, thereby driving the product to move upward. Then, the second electric cylinder 211 drives the second cylinder 210 and the product to move backward integrally (i.e., move toward the side where the intermediate transplanting mechanism 30 is located), thereby driving the product to move to directly above the positioning platform mechanism 40. The piston rod of the second cylinder 210 extends. Subsequently, the first suction cup module releases the product, and the product is placed on the positioning platform mechanism 40. The piston rod of the push plate cylinder 44 extends and cooperates with the baffle 42 to position the product on the positioning platform mechanism 40. The third electric cylinder 53 drives the fourth cylinder 52 and the second suction cup module to move forward integrally (i.e., move toward the side where the intermediate transplanting mechanism 30 is located) and stops when it moves to directly above the positioning platform mechanism 40. The piston rod of the fourth cylinder 52 extends to drive the second suction cup module to move downward. The suction cups of the second suction cup module suck the positioned product on the positioning platform 41. Then, the piston rod of the push plate cylinder 44 retracts, and the piston rod of the fourth cylinder 52 retracts to drive the product to move upward. The third electric cylinder 53 drives the fourth cylinder 52, the second suction cup module, and the product to move backward integrally (i.e., move toward the side where the trimming machine is located). The third electric cylinder 53 transfers the product to the trimming machine. After each mechanism completes its action, it resets to the initial state and enters the next working cycle;

[0056] If the product is facing downwards, the piston rod of the second cylinder 210 retracts, thereby driving the product to move upwards. The flipping cylinder 29 drives the first suction cup module and the product to flip 180°, so that the product faces upwards. Then, the second electric cylinder 211 drives the second cylinder 210 and the product as a whole to move backward (i.e., move towards the side where the intermediate transfer mechanism 30 is located), thereby driving the product to move between the positioning platform mechanism 40 and the intermediate transfer mechanism 30. The piston rod of the fifth cylinder 32 of the intermediate transfer mechanism 30 extends a certain distance, and the third suction cup module sucks the top surface of the product. The first suction cup module releases the product. The second electric cylinder 211 drives the first suction cup module to move forward to the front end of the sliding table stroke of the second electric cylinder 211. The flipping cylinder 29 drives the first suction cup module to flip 180° so that the suction nozzle 27 of the suction cup faces downwards for resetting; the piston rod of the fifth cylinder 32 continues to extend, and the third suction cup module places the product on the positioning platform mechanism 40. The piston rod of the push plate cylinder 44 extends and cooperates with the baffle 42 to position the product on the positioning platform mechanism 40; the third electric cylinder 53 drives the fourth cylinder 52 and the second suction cup module as a whole to move forward (i.e., move towards the side where the intermediate transfer mechanism 30 is located). When it moves directly above the positioning platform mechanism 40, it stops. The piston rod of the fourth cylinder 52 extends to drive the second suction cup module to move downwards. The suction cup of the second suction cup module sucks the positioned product on the positioning platform 41. Then, the piston rod of the push rod cylinder retracts, the piston rod of the fourth cylinder 52 retracts to drive the product to move upwards, and the third electric cylinder 53 drives the fourth cylinder 52, the second suction cup module, and the product as a whole to move backward (i.e., move towards the side where the trimming machine is located). The third electric cylinder 53 transfers the product to the trimming machine. After each mechanism completes its action, it resets to the initial state and enters the next working cycle.
