[0032] like Figure 1 and Figure 2 As shown, the turnover box includes a box body 1 and a box cover 2. The small tea cans 3 are supported by blister trays 4, and the multi-layer blister trays 4 are sequentially placed into the box body 1. The outer dimensions of the turnover box are: 600*400*375mm, and the inner dimensions are: 556*356*355mm.

[0033] like Figure 3 and Figure 4 As shown, a blister support partition 4 needs to be arranged between the multi-layer small can products, and hand-picking holes 5 with a diameter of 20 mm are set on both sides of the blister support partition 4. Multiple rows of slots 6 for placing small can tea products 3 are evenly arranged between the hand-picking holes 5 on both sides, and ventilation holes 8 are also set between each row of grooves 6. Limiting grooves 7 are set around the periphery of the blister support partition 4. The blister support partitions 4 will be stacked together in front of the box body 1. The limiting grooves 7 can prevent the blister support partitions 4 from being too tightly stuck to each other when stacked.

[0034] like Figure 5As shown, the automatic can picking and boxing machine includes a diversion and sorting device 10, an equally spaced suction and separation device 20, a box conveying and automatic positioning device 30, a box cover operation device 40, and a partition removal device 50 installed on a frame 60. The diversion and sorting device 10 is used to divide the small can products 3 into two columns, the equally spaced suction and separation device 20 is used to suck a set number of small can products 3 in the same column and place them into the blister support partition 4 in the box body 1, the box conveying and automatic positioning device 30 is used to transport the box body 1, the box cover operation device 40 is used to remove the upper box cover 2 of the box body 1 before boxing, and put the box cover 2 back on the top of the box body 1 after the box body 1 completes the boxing of the small can products 3, and the partition removal device 50 is used to put a new blister support partition 4 into the box body 1.

[0035] The frame 60 includes a transverse fixing frame 61, a longitudinal fixing frame 62, a front drive roller fixing frame 67, and a rear drive roller fixing frame 68. The equally spaced suction and separation device 20 is provided with a box packing module 27, which is mounted on the left side of the longitudinal fixing frame 62 and can move forward and backward along the longitudinal fixing frame 62. The box conveying and automatic positioning device 30 includes a box conveyor belt 32, which is located between the front drive roller fixing frame 67 and the rear drive roller fixing frame 68. The cover removal module 41 of the box cover operation device 40 is mounted on the rear end of the transverse fixing frame 61 and can move left and right along the transverse fixing frame 61. The cover installation module 43 of the box cover operation device 40 is mounted on the right end of the longitudinal fixing frame 62 and can move forward and backward along the longitudinal fixing frame 62. The partition removal module 51 of the partition removal device 50 is mounted on the front end of the transverse fixing frame 61 and can move left and right along the transverse fixing frame 61. Furthermore, the box packing module 27, the cover removing module 41, the cover installing module 43 and the partition removing module 51 are all linear modules.

[0036] The frame 60 also includes a feed roller 63, a first rotary roller 65, a second rotary roller 66, and a discharge roller 64. The feed roller 63 is used to transport unpacked turnover boxes. A first rotary roller 65 is provided between the feed roller 63 and the rear drive roller fixing frame 68. The first rotary roller 65 rotates the turnover box 90 degrees and then transfers it to the rear drive roller fixing frame 68. The box cover operation device 40 sucks up the box cover 2. The box conveying and automatic positioning device 30 transfers the box body 1 from the rear drive roller fixing frame 68 to the front drive roller fixing frame 67 for packing. The partition removal device 50 on the left side of the front drive roller fixing frame 67 is used to place the blister support partition 4 to achieve layered packing of the box body 1. After the small can tea products are packed, the box cover operation device 40 places the box cover 2 back on the box body 1. The turnover box reaches the rear end of the front drive roller fixing frame 67 and is sent to the discharge roller 64 via the second rotary roller 66.

[0037] The feed roller 63 , the first rotating roller 65 , the second rotating roller 66 , the discharge roller 64 , the front drive roller fixing frame 67 and the rear drive roller fixing frame 68 are all equipped with drive rollers.

[0038] like Figure 6 As shown, the diversion and sorting device 10 includes a main conveyor line 11, a branch conveyor line 12, a first shifting rod 13, a second shifting rod 14, and a rotating hair roller 15. The first shifting rod 13 is installed at the bifurcation of the main conveyor line 11 and the branch conveyor line 12. The branch conveyor line 12 is provided with a column partition, which divides the small can buffer station 16 into two columns, front and back, through the column partition. The second shifting rod 14 is installed on the right side of the column partition. Rotating hair rollers 15 are installed on both the front and back sides of the branch conveyor line 12.

[0039] The diversion and sorting device 10 is used to sort the small can products 3. It can guide the small can products 3 on the main conveyor line 11 to the branch conveyor line 12 via a first shifting rod 13. At the same time, the small can products 3 are separated into two rows on the branch conveyor line 12 by a second shifting rod 14. After the small can products 3 are separated, the rotating hair roller 15 guides the easy-tear edges of the small can products 3 to the same side. The small can products 3 arrive at the small can buffer station 16 at the end of the branch conveyor line 12, waiting to be sucked up by the evenly spaced suction and separation device 20 and placed into the blister tray 4 in the box body 1.

[0040] The first lever 13 is a channel divider driven by a cylinder. When the channel divider is opened, the small cans can flow to this device. The first lever 14 is a channel divider driven by a cylinder, which evenly distributes the small cans into the downstream dual channels. After the sorting state, two rows of small cans are sucked in at a time. The rotating brush 15 uses a rotating brush to accelerate the rotation of the can body (the brush does not damage the can body). When the tear-off film on the surface of the small can product 3 rotates to the edge of the guardrail and is blocked and cannot continue to rotate, it maintains the existing direction, which can ensure that the tear-off direction of all small cans is consistent.

[0041] like Figure 7 and Figure 8 As shown, the equally spaced separation device 20 includes a connecting bracket 21, a first cylinder 22, a second cylinder 23, a suction cup fixing bracket 24, a connecting rod mechanism 25, a suction nozzle 26, a mounting bracket, and a packing module 27. The connecting bracket 21 is fixedly mounted on the packing module 27. When the packing module 27 drives the connecting bracket 21 forward, the connecting bracket 21 reaches above the small can buffer station 16. When the connecting bracket 21 is driven to move backward, the connecting bracket 21 reaches the canning station 33.

[0042] The multiple suction cup mounts 24 are connected by a linkage mechanism 25. The suction cup mounts 24 on both sides are connected to the connecting bracket 21 via mounting brackets, including a left mounting bracket 28 and a right mounting bracket 29. The linkage mechanism 25 includes multiple sets of "X"-shaped rods connected in sequence. The centers of the "X"-shaped rods are connected to the middle of the suction cup mounts 24 via shafts, and adjacent "X"-shaped rods are also connected by shafts. In this way, when the linkage mechanism 25 extends, it drives the multiple suction cup mounts 24 to extend toward the sides. When the linkage mechanism 25 contracts, it drives the multiple suction cup mounts 24 to contract.

[0043] The first cylinder 22 and the second cylinder 23 are installed in sequence above the connecting bracket 21. The left side of the first cylinder 22 is fixedly connected to the left mounting bracket 28, and the right side is fixedly mounted on the connecting bracket 21 by bolts. The left side of the second cylinder 23 is fixedly mounted on the connecting bracket 21 by bolts, and the right side is fixedly connected to the right mounting bracket 29. Baffles are provided on the left and right sides of the connecting bracket 21 to prevent the mounting bracket from detaching from the connecting bracket 21, so that the connecting rod mechanism 25 is driven by the first cylinder 22 and the second cylinder 23.

[0044] A suction nozzle 26 is provided below the suction cup fixing frame 24 , and the suction nozzle 26 is driven by a negative pressure device. When the negative pressure device is working, the suction nozzle 26 generates suction, thereby sucking the small can product 3; conversely, when the negative pressure device is not working, the small can product 3 falls off from the suction nozzle 26 .

[0045] During use, after the small can products 3 pass through the diversion and sorting device 10 and arrive at the small can buffer station 16, they are divided into two rows, with the small can products in each row close together. The equally spaced separation device 20, with the suction nozzle 26 in the retracted state, sucks up one row of small can products 3, and then the first cylinder 22 and the second cylinder 23 move, separating the spacing between the small can products 3 through the connecting rod mechanism 25, making it easier to load them into the slots 6 of the blister support partition 4. After placement, the equally spaced separation device 20 returns to the retracted state and then sucks up another row of small can products 3. Then the first cylinder 22 and the second cylinder 23 move, separating the spacing between the small can products 3, and continue to load them into the slots 6 of the blister support partition 4. In this way, the two rows of small can products will be placed into the blister support partition 4 in sequence.

[0046] like Figure 9 As shown, the box conveying and automatic positioning device 30 includes a lifting device 31, a box conveyor belt 32 and a positioning device. The lifting device 31 is installed below the rear end of the rear end drive roller fixing frame 68, and is used to lift the box body 1 upward to the entrance of the box conveyor belt 32. The box conveyor belt 32 transfers the box body 1 from the rear end drive roller fixing frame 68 to the front end drive roller fixing frame 67. The front end drive roller fixing frame 67 is provided with a positioning device for limiting the position of the box body 1.

[0047] The positioning device includes a limit positioning device 35 and a lateral blocker 34. The lateral blocker 34 includes a first positioning rod and a third cylinder connected to the first positioning rod, and the third cylinder controls the first positioning rod to rise and fall.

[0048] The position limiting and positioning device 35 includes a second positioning rod and a fourth cylinder connected to the second positioning rod, which is used to determine the front and rear positions of the box body 1 when it reaches the canning station 33. The second positioning rod is in a vertical position. When the box body 1 is moving from the box conveyor belt 32 to the canning station 33, the second positioning rod located at the front end of the canning station 33 determines the front position of the box body 1. Then, the fourth cylinder is activated, driving the second positioning rod to move backward, thereby making the box body 1 close to the side of the box conveyor belt 32.

[0049] During operation, the box 1 moves from left to right along the rollers of the front drive roller mounting bracket 67. The first positioning rod of the lateral blocker 34, driven by the third cylinder, rises from the bottom to block the box 1. Then, the second positioning rod of the position limiting positioning device 35, driven by the fourth cylinder, pushes the box 1 backward. A baffle is provided on the side of the front drive roller mounting bracket 67 near the rear drive roller mounting bracket 68. The baffle and the second positioning rod limit the position of the box 1.

[0050] In this way, the cylinder drives the positioning rods of the limit positioning device 35 and the lateral blocker 34 to clamp the box body 1, thereby ensuring that the position of the box body 1 is fixed.

[0051] like Figure 10 As shown, the box cover operation device 40 includes a cover removal module 41, a transfer conveyor belt 42, and a cover installation module 43. The cover removal module 41 is installed at the rear end of the horizontal fixing frame 61 and is provided with a first suction cup 47 for sucking the box cover 2 at the cover removal station 44. The cover removal module 41 then moves left and right along the horizontal fixing frame 61 to place the box cover 2 on the left side of the box cover conveyor belt 42; the transfer conveyor belt 42 is located at the rear end of the horizontal fixing frame 61 and is arranged parallel to the horizontal fixing frame 61, and is used to transport the box cover 2 to the box cover buffer 45 at the right end; the cover installation module 43 is installed at the right end of the longitudinal fixing frame 62 and can move back and forth along the longitudinal fixing frame 62. After the turnover box is loaded with materials, the second suction cup 48 provided by the cover installation module 43 moves the box cover 2 to the cover installation station 46 and installs it back on the turnover box.

[0052] The cover removal station 44, the box cover buffer 45 and the cover installation station 46 are all provided with infrared sensors. When the box body or the box cover 2 is in place, the operation of the cover removal module 41, the transfer conveyor belt 42 and the cover installation module 43 is controlled.

[0053] like Figure 11As shown, the partition removal device 50 includes a partition removal module 51, which is installed at the front end of the horizontal fixing frame 61 and can move left and right along the horizontal fixing frame 61. The partition removal module 51 is provided with a robot 52, which can grab the blister support partition 4 from the partition storage station 53 and place the blister support partition 4 in the box body 1.

[0054] The robot arm 52 is rectangular, with spring-loaded suction cups 54 at each of the four corners of the lower portion of the rectangle, used to pick up the separators within the turnover box. Springs are located on the outside of the suction cups 54 to ensure maximum contact with the separators without crushing them. The system records the number of separators picked up. Once all the separators have been removed, the turnover box becomes empty and returns to position 44.

[0055] like Figure 12 As shown, when the present invention is used, there are several steps: feeding semi-finished small cans, receiving turnover boxes, automatically packing small cans, and discharging full boxes, which are specifically described as follows:

[0056] S1: feeding of semi-finished small cans:

[0057] Through the conveyor belts of the main conveyor line 11 and the branch conveyor line 12 and two levers, the small can products 3 are sent to the small can buffer station 16 in separate lanes, ensuring the time for packing and the time for placing the blister tray partition 4 so that production is uninterrupted; before the small can products 3 enter the small can buffer station 16, a rotating hair roller 15 is provided as a guide device on the branch conveyor line 12 to guide the easy-tear direction of the small can products 3 to be consistent within the range of ±30° to avoid overlapping with each other; after the small can products 3 enter the small can buffer station 16, the small can buffer station 16 is arranged with partitions to prevent the can bodies of the small can products 3 from colliding and squeezing with each other, causing scratches and dents.

[0058] S2: Incoming turnover boxes:

[0059] Initiate material requests for turnover boxes (empty turnover boxes, partition turnover boxes) to the upper system (workshop logistics scheduling system WCS) and receive the turnover boxes. The turnover box materials are transported by AGV carts;

[0060] There are two buffer boxes at the feed roller 63, and a box cover operation device 40 is set;

[0061] The entrance of the automatic can picking and packing machine needs to be equipped with a barcode scanner to scan the two-digit code information of the turnover box and check and judge it with the upper system.

[0062] S3: Canning in turnover boxes:

[0063] Automatically suck and position the partition, and suck 3 small cans of products into the partition groove (using the rectangular coordinate machine module), requiring the small cans of products to be accurately positioned in the partition groove;

[0064] Automatically absorb the partitions and place the whole plate into the empty turnover box. The canned turnover box is automatically transported out of the packing station.

[0065] Complete data statistics and update turnover box material information;

[0066] S4: Full box discharge:

[0067] After packing is completed, scan the turnover box two-digit code, bind the information with the box, and output the turnover box material information to the upper system;

[0068] Automatically absorb the box cover to complete the box cover process;

[0069] Initiate AGV transportation requirements and deliver turnover boxes to the AGV docking port, waiting for loading and transportation;

[0070] The discharge roller 64 is provided with two buffer boxes.

[0071] The automatic can picking and packing machine replaces the repetitive work of manual can picking and packing, reduces manual packing, and material loss caused by item handling, can save 2-3 operators (single shift), and realizes AGV automatic delivery and reception of material boxes to equipment entrance and exit stations (empty turnover boxes, partition turnover boxes, full turnover boxes). The present invention automatically completes processes such as can picking, packing, placing partitions, and placing box covers.
