Description

Technical Field

[0001] The utility model relates to the technical field of packaging devices, in particular to an automatic case packing machine. Background Art

[0002] Liquid preparations are typically packaged in bottles with individual packaging boxes. Manual packing is not only costly but also time-consuming and labor-intensive. Take cod liver oil emulsion as an example: each bottle contains 500ml, and each box contains 30 bottles. Packing is labor-intensive, requiring six people to complete the subsequent code scanning and packing operations, including two people to straighten the products output by the cartoning machine, one person to scan the supervision code, and three people to pack and bundle the boxes. The three box packers and bundlers handle an average of 2 to 4 tons of product per day. The high labor intensity of boxing not only causes physical harm to the operators, but also easily leads to work-related accidents such as lumbar sprains.

[0003] Currently, there are also packaging devices that use a pushing method to push the packaging box containing liquid preparations into the outer box. Although this can reduce some manual labor processes, during packing, the four folded edges at the opening of the outer box are folded inward, resulting in the packaging box containing the liquid preparations being unable to be pushed into the outer box, which may cause product damage and subsequent squeezing of the packaging box.

[0030] Example

[0031] Combine Figures 1 to 8 As shown, this embodiment provides an automatic cartoning machine, including a feeding conveying mechanism 1 and an outer box 14 conveying mechanism, and also includes a cartoning device 4, the cartoning device 4 includes a first box pushing mechanism 5, a lifting box loading bin mechanism 6 and a second box pushing mechanism 7.

[0032] The outer box 14 conveying mechanism is provided with a box turning mechanism 8 for turning the outer box 14 90 degrees so that the opening of the outer box 14 is horizontally facing the loading port 26; the first box pushing mechanism 5 is used to push the products 17 horizontally into the lifting loading bin 21 and cooperate with the lifting loading bin mechanism 6 to stack multiple products 17 in layers in the loading bin 21;

[0033] A plurality of guide plates 25 are flippably provided on the pushing and loading port 26; the second box pushing mechanism 7 is used to push the products 17 stacked in layers in the box loading bin 21 into the outer box 14 through the pushing and loading port 26; the guide plates 25 are configured to drive the four folded edges of the opening of the outer box 14 to flip outward during the pushing and loading process of the second box pushing mechanism 7.

[0034] By cooperating with the first box pushing mechanism 5 and the lifting box loading bin mechanism 6, multiple products 17 are stacked in layers in the box loading bin 21, and then pushed and packed in a one-time manner by the second box pushing mechanism 7; and the arrangement of multiple reversible guide plates 25 on the pushing opening 26 can drive the four folded edges of the opening of the outer box 14 to flip outward during the pushing and loading process of the second box pushing mechanism 7, so that the layered stacked products 17 can smoothly enter the outer box 14, avoiding the situation where the four folded edges at the opening of the outer box 14 flip inward, resulting in the product 17 being unable to be pushed into the outer box 14, causing damage to the product 17, and subsequent squeezing of the packaging box.

[0035] It should be noted that Figure 1 and Figure 2 The box turning mechanism 8 is a schematic diagram in two states. Figure 3 Only one box turning mechanism 8 is shown.

[0036] Specifically, in this embodiment, Figure 4 and Figure 5 As shown, the box turning mechanism 8 includes a bracket 9, a first drive 10 that drives the bracket 9 to turn, a fixed plate 11 disposed on one side of the turning axis of the bracket 9, a clamping plate 12 disposed on the other side of the bracket 9, and a second drive 13 for driving the clamping plate 12 to move. When the outer box 14 is transferred to the position of the box turning mechanism 8 on the outer box 14 conveying mechanism, the second drive 13 is activated to drive the clamping plate 12 to move, clamping the outer box 14 between the fixed plate 11 and the clamping plate 12, at which point the opening of the outer box 14 faces upward. The first drive 10 then drives the outer box 14 to turn 90 degrees between the fixed plate 11 and the clamping plate 12, at which point the opening of the outer box 14 faces the loading port 26. A sensor can be provided on the outer box 14 conveying mechanism to provide an electrical signal when the outer box 14 enters the position of the box turning mechanism 8, so as to activate the second drive 13 to clamp the outer box 14; or a reversible limit device can be provided at an appropriate position to limit the position of the outer box 14; thereby ensuring that the outer box 14 can be clamped by the box turning mechanism 8 at the correct position and then turned over. It should be noted that Figure 4 and Figure 5 Schematic diagram of the structure of the box turning mechanism 8 in two states.

[0037] like Figure 6 As shown, the first box pushing mechanism 5 includes a first push plate 15 and a third drive 16 for driving the first push plate 15 to move. The first push plate 15 is used to push a plurality of horizontally arranged products 17 into the box loading chamber 21. For example, for cod liver oil emulsion 17, each outer box 14 contains 30 bottles, packed in six layers of five bottles each. Therefore, each time the third drive 16 drives the first push plate 15 to move, it pushes the five horizontally arranged bottles 17 into the box loading chamber 21.

[0038] like Figure 7As shown, the loading bin lifting mechanism 6 includes a plurality of vertically arranged guide rails 18, a screw module 19 connected to the loading bin 21, and a fourth drive 20 connected to the screw module 19. The loading bin 21 is open along the direction of movement of the first push plate 15. After each layer of products 17 is pushed into the loading bin 21 by the first pushing mechanism 5, the fourth drive 20 lowers the loading bin 21 via the screw module 19. The first pushing mechanism 5 then pushes the next layer of products 17, and this cycle repeats until the loading bin 21 is fully stacked.

[0039] like Figure 8 As shown, the second box pushing mechanism 7 includes a plurality of slide bars 22, a second push plate 23 movably mounted on the slide bars 22, and a fifth drive 24 for driving the second push plate 23 to move. When the box loading chamber 21 is filled with stacked products 17, its opening is lowered to align horizontally with the loading opening 26. At this point, the fifth drive 24 drives the second push plate 23 to push the stacked products 17 through the loading opening 26 into the outer box 14. During this pushing process, the products 17 push outward against the four guide plates 25 located at the loading opening 26. These guide plates 25 then cause the four folded edges of the outer box 14 opening to tilt outward, allowing the stacked products 17 to smoothly enter the outer box 14. The box turning mechanism 8 then turns the outer box 14 again, so that its opening faces upward, allowing it to continue to be transported to the next step.

[0040] The first drive 10 and the fourth drive 20 above use servo motors; the second drive 13, the third drive 16 and the fifth drive 24 use cylinders.

[0041] Preferably, four guide plates 25 are elastically hinged on the push-in opening 26, and under the action of elastic force, they are in a closed state when not pushed by external forces. The elastically hinged guide plates 25 are in a closed state when not pushed by external forces, which can effectively ensure that when the guide plates 25 are opened, they can drive the four folded edges of the opening of the outer box 14 to flip outward. At the same time, during packing, the four sides of the layered stacked products 17 can be tightly pressed to allow the layered stacked products 17 to better enter the outer box 14. In other embodiments, the guide plates 25 placed on the upper side can also be fixed horizontally, so that after the outer box 14 is flipped, the folded edges on the upper side of the flipped outer box 14 can be limited to the outside of the guide plates 25.

[0042] In this embodiment, the feeding and conveying mechanism 1 is a conveyor belt; a first code scanning mechanism (not shown in the drawings) is provided on the conveyor belt. The first code scanning mechanism scans the QR code of product 17 on one end face of product 17. The outer box 14 conveying mechanism is a roller conveying mechanism, which includes a first roller conveyor line 2 and a second roller conveyor line 3 whose conveying directions are perpendicular to each other; the box turning mechanism 8 is provided on the first roller conveyor line 2; a second code scanning mechanism 27 is provided on the second roller conveyor line 3. After the product 17 is packed, the QR code on one end face of the product 17 is placed on the opening side of the outer box 14, and the second code scanning mechanism 27 scans the QR code of the product 17 and compares it with the result of the scan by the first code scanning mechanism; when the results of the two scans after the comparison are inconsistent, the packing operation is stopped, or an alarm is issued to ensure the number of products packed.

[0043] Furthermore, a sealing and packaging device 28 is included, which is connected to the second roller conveyor line 3 and is used to seal the four folded edges at the opening of the outer box 14.

[0044] It should be noted that liquid preparations of medicines are usually packaged in separate cartons, so the product 17 described above refers to a product 17 packaged in a separate carton. Of course, in other embodiments, the product 17 may also be packaged in a separate bottle, but the bottle is preferably square for easy stacking.
