[0045] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0046] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0047] Reference Figures 1 to 10 As shown, a five-pack commodity sealing and cutting machine comprises a feeding unit 1, a folding unit 2, a flipping unit 3, an arranging unit 4, a bag making unit 5 and a sealing unit 6. The feeding unit 1 conveys the five-pack commodity in a horizontal position to the folding unit 2. The folding unit 2 folds the five-pack commodity and conveys the folded five-pack commodity to the flipping unit 3. The flipping unit 3 flips the folded five-pack commodity into a flat position and conveys it to the arranging unit 4. The arranging unit 4 arranges a plurality of five-pack commodities in a flat position in a row and conveys them to a packaging bag made by the bag making unit 5. The sealing unit 6 seals the packaging bag.

[0048] The structure of the feeding unit 1 can refer to the feeding conveying mechanism in patent 201911031182.8. Of course, the feeding unit 1 can also be a conveyor belt device or a chain network conveying device, which is responsible for conveying the original horizontally placed five-pack goods to the folding unit 2.

[0049] Reference Figures 2 to 6 The folding unit 2 includes two side plates 21 arranged at intervals, the two side plates 21 are connected by rollers 22, the rollers 22 are two and arranged at intervals in the horizontal direction, the two rollers 22 are connected to a conveyor belt group 23, the conveyor belt groups 23 are two and arranged at intervals along the axial direction of the rollers 22, a positioning plate 24 is provided above the conveyor belt group 23, a groove is formed between the two side plates 21, and the groove is connected to the feeding unit 1;

[0050] The feeding unit 1 conveys the five-pack of goods to the conveyor belt group 23, and places the center package of the five-pack of goods on the positioning plate 24;

[0051] A first folding push rod assembly 25 and a second folding push rod assembly 26 are provided between the two conveyor belt groups 23. There are two first folding push rod assemblies 25 and they are located on both sides of the positioning plate 24. There are two second folding push rod assemblies 26 and they are located on both sides of the positioning plate 24. The first folding push rod assembly 25 is located on the side of the second folding push rod assembly 26 away from the positioning plate 24. The first folding push rod assembly 25 pushes the edge package of the five-pack commodity to rotate upward in the direction close to the positioning plate 24, and the second folding push rod assembly 26 pushes the package adjacent to the edge package in the five-pack commodity to rotate upward in the direction close to the positioning plate 24.

[0052] Two limit rods 27 are provided above the conveyor belt group 23. The two limit rods 27 are arranged at intervals along the moving direction of the five-pack commodity. The two limit rods 27 are symmetrically arranged about the positioning plate 24. The two limit rods 27 are raised and lowered under the drive of the fourth cylinder 271. A first pressing plate 28 is provided above the positioning plate 24. The first pressing plate 28 is raised and lowered under the drive of the fifth cylinder 281. When the first pressing plate 28 is lowered, the first pressing plate 28, the positioning plate 24 and the limit rods 27 cooperate to maintain the posture of the folded five-pack commodity.

[0053] A first opening 211 is provided on one of the side plates 21, and a second opening 212 is provided on the other side plate 21. The first opening 211 and the second opening 212 both correspond to the positioning plate 24. A first cylinder 213 is provided on a side of the first opening 211 away from the positioning plate 24, and a push plate 214 is provided at the output end of the first cylinder 213.

[0054] The two side plates 21 form a channel. When the five-pack of goods is transported to the conveyor belt group 23, the channel can limit the position of the five-pack of goods to prevent the five-pack of goods from moving around. Since the conveyor belt groups 23 are arranged at intervals, there is a gap between the two conveyor belt groups 23 to facilitate the movement of the first folding push rod assembly 25 and the second folding push rod assembly 26. The center package of the five-pack of goods is located on the positioning plate 24. Therefore, the center package of the five-pack of goods does not need to be folded. When the center package of the five-pack of goods reaches the positioning plate 24, the first folding push rod assembly Component 25 is actuated first, and the first folding push rod assembly 25 pushes the edge packages of the five-pack product to rotate upward in the direction close to the positioning plate 24. At this time, it is the first folding, so that the two edge packages of the five-pack product are folded up first, and then the second folding push rod assembly 26 is actuated, and the second folding push rod assembly 26 pushes the packages adjacent to the edge packages in the five-pack product to rotate upward in the direction close to the positioning plate 24. At this time, it is the second folding. The posture of the folded five-pack product is similar to a concave shape, which reduces the space occupied by the five-pack product after folding; refer to Figure 2 , showing the comparison between the original posture of the five-pack product and the posture after folding;

[0055] Before folding, the first pressing plate 28 will drop, and the bottom contour of the first pressing plate 28 is convenient for forming the five-pack product during folding. The limiting rod 27 is initially in a low position, and the five-pack product will be above the limiting rod 27. When the second folding push rod assembly 26 completes the pushing action, the limiting rod 27 will rise, so that the folded five-pack product is stuck between the two limiting rods 27. The first pressing plate 28, the positioning plate 24 and the limiting rod 27 cooperate to maintain the posture of the folded five-pack product to prevent the five-pack product from falling apart.

[0056] When the first pressing plate 28, the limiting rod 27 and the positioning plate 24 hold the five-pack commodity, the first cylinder 213 will be activated, and the first cylinder 213 can drive the pushing plate 214 to push the five-pack commodity in the maintained posture out of the second opening 212, so that the folded five-pack commodity enters the flip unit 3;

[0057] A corresponding notch may be provided on the push plate 214 to avoid the limiting rod 27 and the first pressing plate 28 .

[0058] In practice, there is a frame outside, the side plate 21 can be fixed on the frame, and the positioning plate 24 is fixed on the side plate 21 .

[0059] In this embodiment, the conveyor belt set 23 includes two rubber rings, which can increase the support points to ensure that the five-pack of goods will not fall. One of the rollers 22 is driven by a motor to rotate. When the five-pack of goods is transported in, the roller 22 is also rotating to assist the movement of the five-pack of goods and prevent the five-pack of goods from being stuck on the conveyor belt set 23.

[0060] Moreover, the length of the groove constructed by the two side panels 21 is adapted to the length of the five-pack of goods. The feeding unit 1 is connected to one end of the groove, and a corresponding sensor can be set at the end of the groove away from the feeding unit 1. After detecting the product coming over, it can be determined that the five-pack of goods has completely entered the groove, and the feeding unit 1 is stopped. At this time, the center package of the five-pack of goods will be on the positioning plate 24.

[0061] In this embodiment, a pressing module 29 is provided between the first folding push rod assembly 25 and the second folding push rod assembly 26. The pressing module 29 includes a second cylinder 291 and a mounting seat 292 arranged at the output end of the second cylinder 291. A third cylinder 293 is provided on the mounting seat 292. The extension direction of the third cylinder 293 is parallel to the axial direction of the roller 22. The piston rod of the third cylinder 293 can reach the top of the conveyor belt group 23. The third cylinder 293 drives the mounting seat 292 to rise and fall.

[0062] Before the first folding push rod assembly 25 is actuated, the mounting seat 292 is in a high position, and the third cylinder 293 is actuated first, allowing the piston rod of the third cylinder 293 to pass through the side plate 21 to reach above the connection between the edge package of the five-pack product and the adjacent package, and then the second cylinder 291 is actuated to lower the mounting seat 292, so that the piston rod of the third cylinder 293 presses the connection between the edge package of the five-pack product and the adjacent package, and then the first folding push rod assembly 25 is actuated again to ensure that the adjacent packages will not move when the edge package of the five-pack product is pushed, thereby ensuring the folding effect; then the second cylinder 291 and the third cylinder 293 are reset, and the second folding push rod assembly 26 is actuated again.

[0063] In this embodiment, the first folding push rod assembly 25 and the second folding push rod assembly 26 are both composed of a cylinder and a cushion block. The cushion block is arranged at the output end of the cylinder. The cylinder drives the cushion block to move, thereby driving the package of the five-pack product to rotate.

[0064] Reference Figures 7 and 8 The flip unit 3 includes a receiving module 31, a pressing module 32 and a pushing module 33. The pressing module 32 includes a sixth cylinder 321 and a second pressing plate 322 arranged at the output end of the sixth cylinder 321. The sixth cylinder 321 drives the second pressing plate 322 to rise and fall.

[0065] The receiving module 31 includes a slide 311 and a seventh cylinder 312 driving the slide 311 to slide along the moving direction of the push plate 214. The slide 311 is located on the side of the second opening 212 away from the positioning plate 24. A rotating shaft 313 is provided on the slide 311. The axis of the rotating shaft 313 is parallel to the extension direction of the groove. The rotating shaft 313 rotates under the drive of the first driving member 314. A receiving frame 315 is fixed on the rotating shaft 313. A receiving plate 316 is fixed on the slide 311. The receiving frame 315 is used to load the folded five-pack of goods. The slide 311 slides back and forth to allow the receiving frame 315 to receive the five-pack of goods from the second opening 212 or to allow the flipped five-pack of goods to be located below the second pressing plate 322.

[0066] The pushing module 33 includes an eighth cylinder 331 and a pushing block 332 arranged at the output end of the eighth cylinder 331. The extension direction of the eighth cylinder 331 is parallel to the axial direction of the rotating shaft 313.

[0067] Under the action of the slide 311, the receiving frame 315 is in a position close to the second opening 212, and the second opening 212 transports the folded five-pack of goods into the receiving frame, and then the rotating shaft 313 drives the receiving frame 315 to flip downward and backward 90 degrees, so that the five-pack of goods becomes a flat posture and reaches the top of the receiving plate 316. At the same time, the slide 311 also moves in the direction away from the second opening 212, so that the flipped five-pack of goods is located below the second pressing plate 322, and then the second pressing plate 322 is actuated to push the five-pack of goods in the receiving frame 315 onto the receiving plate 316. At this time, the five-pack of goods is placed on the receiving plate 316 in a flat posture and is not easy to spread out. Then the push block 332 is actuated again to push the five-pack of goods on the receiving plate 316 to the arrangement unit 4.

[0068] In this embodiment, the receiving frame 315 includes a rectangular frame, and the chamber constructed by the rectangular frame can accommodate and limit the folded five-pack of goods to prevent the folded five-pack of goods from spreading out. One of the open ends of the chamber is provided with a limiting card plate, and the limiting card plate is fixed on the rectangular frame. When the receiving frame 315 receives the product from the second opening 212, the limiting card plate is located on the side of the rectangular frame away from the second opening 212, thereby preventing the folded five-pack of goods from leaving the chamber; when the receiving frame 315 is completely flipped 90 degrees downward, the limiting card plate will be located on the side of the rectangular frame away from the receiving plate 316, and the limiting card plate will not completely block the open end of the chamber, and the second pressure plate 322 can enter the chamber normally.

[0069] In this embodiment, one end of the receiving plate 316 in the sliding direction of the slide 311 is fixedly connected to the slide 311, and the other end of the receiving plate 316 is provided with a retaining edge 317, which cooperates with the slide 311 to prevent the five-pack of goods on the receiving plate 316 from scattering.

[0070] In this embodiment, the first driving member 314 is a motor.

[0071] Reference Figures 9 and 10 , the arrangement unit 4 includes a buffer plate 41, and the receiving plate 316 can be connected to the buffer plate 41;

[0072] An arranging plate 42 is provided on the buffer plate 41. The extending direction of the arranging plate 42 is parallel to the axial direction of the rotating shaft 313. The arranging plate 42 can move along the sliding direction of the sliding seat 311 under the drive of the second driving member 43. The pushing block 332 pushes the five-pack of goods on the receiving plate 316 onto the buffer plate 41, and the arranging plate 42 pushes the five-pack of goods arranged on the buffer plate 41 into the packaging bag.

[0073] It also includes a blocking plate 44, which is driven by a ninth cylinder 45 to rise and fall;

[0074] When the blocking plate 44 rises, the blocking plate 44 is located on the side of the receiving plate 316 close to the buffer plate 41, and the blocking plate 44 is opposite to the push block 332; when the blocking plate 44 falls, the blocking plate 44 is lower than the upper surface of the buffer plate 41;

[0075] The buffer plate 41 is provided with an arc-shaped piece 46, which is opposite to the push block 332, and the push block 332 can move along the axial direction of the rotating shaft 313;

[0076] There is a gap between the arrangement plate 42 and the buffer plate 41, and the arc-shaped piece 46 is located in the gap. The blocking plate 44, the arrangement plate 42 and the arc-shaped piece 46 cooperate to limit the five-pack of goods on the buffer plate 41 to prevent them from spreading;

[0077] During arrangement, the arc piece 46 is located near the receiving plate 316, and the blocking plate 44 is first in the lowered position; then the push block 332 pushes the five-pack of goods onto the buffer plate 41, and the blocking plate 44 will rise. The blocking plate 44, the arranging plate 42 and the arc piece 46 cooperate to limit the five-pack of goods on the buffer plate 41 to prevent them from dispersing. Since the arc piece 46 is movable, after the blocking plate 44 drops again, the push block 332 can continue to push the five-pack of goods onto the buffer plate 41, and the five-pack of goods will push the arc piece 46 to move until a row of five-pack of goods is arranged on the buffer plate 41. Then, the arranging plate 42 moves to push the five-pack of goods in a row into the packaging bag, or the five-pack of goods in a row can be pushed to the next station of the buffer plate 41 first, and then pushed into the packaging bag at one time after being arranged in more rows.

[0078] In this embodiment, the packaging bag is located at the end of the buffer plate 41 away from the folding unit 2. After the five-pack is folded, it is similar to a concave shape. Therefore, when the arrangement plate 42 pushes the five-pack to move, it will contact the side of the five-pack with the concave portion. In this way, the five-pack will not be scattered when the arrangement plate 42 is pushed. This is why the flip unit 3 flips the five-pack in a specific direction.

[0079] In this embodiment, a guide plate 47 can be fixed on the buffer plate 41, and there are two guide plates 47. The arranged five-pack of goods can be located between the guide plates 47. When the arranging plate 42 pushes the five-pack of goods to move, the guide plate 47 can limit the five-pack of goods, and the five-pack of goods will not disperse after leaving the blocking plate 44 and the arc-shaped plate 46.

[0080] In this embodiment, a guide rail 411 is provided on the buffer plate 41, and the extension direction of the guide rail 411 is parallel to the axial direction of the rotating shaft 313. A slider 412 is provided on the guide rail 411, and an arc-shaped piece 46 is arranged on the slider 412 so that the arc-shaped piece 46 can move. A pulley 413 is provided at one end of the guide rail 411 close to the flip unit 3, and a cable is connected to the slider 412. The cable is wound around the pulley 413, and a counterweight is hung at the lower end of the cable. Relying on the counterweight, the slider 412 has a tendency to move close to the flip unit 3, so that the arc-shaped piece 46 can cooperate with the blocking plate 44 to limit the five-pack of goods. When there is no five-pack of goods between the blocking plate 44 and the arc-shaped piece 46, the arc-shaped piece 46 will return to a position close to the receiving plate 316 under the drive of the counterweight.

[0081] In addition, a spring 414 is connected between the side of the arc piece 46 close to the receiving plate 316 and the slider 412. The arc piece 46 is rotatably set on the slider 412. When the five-pack of goods is pushed from the receiving plate 316 to the buffer plate 41, the five-pack of goods contacts the arc piece 46 and then pushes the arc piece 46 to rotate. The spring 414 allows the arc piece 46 to be close to the five-pack of goods, which has a better limiting effect on the five-pack of goods. When the arrangement plate 42 pushes the five-pack of goods, the five-pack of goods can push the arc piece 46 to rotate, so that the five-pack of goods can be separated from the arc piece 46, and then the elastic force of the spring 414 is used to reset the arc piece 46.

[0082] In this embodiment, a height limiting plate 48 is provided above the buffer plate 41, and the arrangement plate 42 and the arc-shaped sheet 46 are both located between the height limiting plates 48. The height limiting plates 48 can limit the five-pack of goods and prevent the five-pack of goods from tilting.

[0083] In this embodiment, the bag making unit 5 is similar to the bag making and forming mechanism of Patent 201911031182.8. The bag making unit 5 can construct a packaging bag and connect the bag mouth of the packaging bag with the output end of the buffer plate 41;

[0084] After the arrangement plate 42 pushes the product into the packaging bag, the packaging bag with the product will arrive on a conveyor belt, and then the sealing unit 6 seals the sides and ends of the packaging bag. The sealing unit 6 includes an edge sealing mechanism and a transverse sealing mechanism. The edge sealing mechanism and transverse sealing mechanism of Patent 201911031182.8 can be referred to, and other sealing mechanisms can also be used to seal the packaging bag;

[0085] In this embodiment, the second driving member 43 is a linear module.

[0086] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
