[0002] The cartoning system consists of a cardboard conveyor, a product handling unit, and a boxing conveyor. The cardboard conveyor transports cartons to the boxing station of the boxing conveyor, where the original sheets of material are unfolded into finished cartons. Because the conveying path of the cardboard conveyor intersects with the conveying path of the boxing conveyor, the existing conveyor belt design would need to be lengthened to transport the cartons into place, which could affect the natural gravity-induced formation of the packaging cardboard at the boxing station. [Summary of the invention]

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a packaging cardboard conveying component that can convey the packaging cardboard to the boxing station while avoiding affecting the natural shaping of the packaging cardboard by falling by gravity at the boxing station.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0037] Reference Figures 1 to 9 As shown, a box packing device includes a box packing conveying component 1, a cardboard conveying component 2 and a product conveying component 3.

[0038] The boxing conveyor assembly 1 is equipped with a horizontally extending packaging material conveying channel and a packaging material drive assembly 11 with a horizontal motion path. The horizontal motion path corresponds to the packaging material conveying channel, and the corresponding packaging material conveying channel is provided with a boxing station. The corresponding boxing station is equipped with a packaging material forming guide structure 13 to guide the packaging material forming. The cardboard conveyor assembly 2 conveys the packaging material cardboard 200 to the top of the boxing station. The product transport assembly 3 transports the product 400 from the product supporting surface 4 to the top of the boxing station. Under the guidance of the packaging material forming guide structure 13, the packaging material cardboard 200 enters the conveying mechanism for transporting the carton under the influence of the product's weight and is bent into shape at the same time.

[0039] Reference Figures 3 to 5 As shown, the box conveying component 1 further includes a push plate 1111, which is installed on the packaging material driving assembly 11. The packaging material driving assembly 11 drives the push plate 1111 to move unidirectionally along a circular path, and the circular path has a horizontal movement path.

[0040] Furthermore, a packaging material support platform assembly 12 is provided below the boxing station. This assembly includes a packaging material support platform 121 and a lift actuator 122 that raises and lowers the packaging material support platform. Several suction cups 1211 are mounted on the packaging material support platform 121. The shape of the packaging material support platform 121 corresponds to the bottom surface of the packaging material after it is formed, i.e., a rectangular structure. The suction cups 1211 are arranged in a rectangular array on the packaging material support platform 121. The cardboard conveyor assembly 2 transports the packaging material 200 to the boxing station. Before the packaging material is formed, the packaging material support platform 121 rises, and the suction cups 1211 hold the packaging material. The product handling assembly 3 then places the product on the packaging material. As the packaging material falls and forms under the influence of the product's gravity, the packaging material support platform 121 descends simultaneously.

[0041] As an embodiment, the lifting driver is a linear motor, or a similar electric cylinder, etc. In order to guide the lifting of the packaging material carrying platform 121, the packaging material carrying platform 121 is connected to a guide rod 1212, and a guide sleeve is provided corresponding to the guide rod, and the guide rod and the guide sleeve cooperate.

[0042] Specifically, such as Figure 3As shown, the packaging material forming guide structure 13 includes corner positioning blocks 131 positioned corresponding to the four corners of the formed packaging material. The corner positioning blocks 131 are provided with first lateral guide surfaces 1311 corresponding to the left and right sides of the formed packaging material 100. The upper portion of the first lateral guide surface 1311 is an inclined surface for guiding the left and right sides of the packaging material. The upper inclined surface of the first lateral guide surface 1311 is perpendicularly connected to the second lateral guide surface 1312. The second lateral guide surface 1312 is higher than the first lateral guide surface 1311 and has a side flange 1313 on its upper side. The side flange 1313 has a horizontal portion, a vertical portion, and an arc-shaped transition portion connecting the horizontal and vertical portions. The packaging material forming guide structure 13 also includes a rear stop plate 132 located at the rear of the boxing station to guide the forming of the rear side of the packaging material. The packaging material forming guide structure 13 also includes a front stop plate 1112 located at the front of the boxing station to guide the forming of the front side of the packaging material. It is understandable that the upper portions of the rear limiting plate 132 and the front limiting plate 1112 are both provided with guiding inclined surfaces.

[0043] The rear limit plate 132 is set at the input end of the packaging material conveying channel, so it can be fixed. The front limit plate 1112 is driven by the packaging material driving assembly 11 to move unidirectionally along the circular path. When it moves to the front side of the packing station, it guides the front side of the packaging material to form.

[0044] In this embodiment, the packaging material drive assembly 11 includes a chain and a sprocket. The chain is mounted on the sprocket and unfolds to form a ring-shaped structure with curved ends and a straight center. Two sets of packaging material drive assemblies are provided, corresponding to the first and second chains 111 and 112. Each of the first and second chains 111 and 112 includes two chains that are parallel to each other. The front and rear ends of the two packaging material drive assemblies share a sprocket shaft 113, one of which is driven by a drive motor 114, while the other is driven by the chain to rotate together. Due to the shared sprocket shaft 113, the first and second chains 111 and 112 operate synchronously. The two chains of the first chain 111 are evenly spaced along the circular motion path with several pairs of push plates, while the two chains of the second chain 112 are evenly spaced along the circular motion path with several pairs of front limit plates 1112. Each pair of push plates 1111 and a corresponding pair of front stop plates 1112 form a push plate and stop plate assembly. When the front stop plates reach the front of the packing station, they guide the front side of the packaging material into shape. Because the packaging material 100 is rectangular, the spacing between two adjacent push plate and stop plate assemblies corresponds to the width of the packaging material 100. It will be appreciated that the installation position of the push plates and front stop plates can be adjusted according to the width of the packaging material 100, and accordingly, the spacing between two adjacent push plate and front stop plate assemblies can be varied.

[0045] Furthermore, the boxing conveyor 1 also includes limit rods 14 provided on the left and right sides of the horizontal motion path. The limit rods 14 are located outside the chain and guide and limit the sides of the formed packaging material 100 as it is conveyed along the packaging material conveying channel.

[0046] To guide the push plate 1111 and front stop plate 1112 along the chain, guide plates 15 are provided on either side of the chain's width. Guide grooves are provided on the push plate 1111 and front stop plate 1112, and these guide grooves slidably engage with the guide plates 15. Grooves can be provided on the bottom sides of the push plate and front stop plate, and the bottom sides of the push plate and front stop plate are fixedly connected to side plates via screws. The side plates mate with the grooves to form guide grooves. The guide plates 15 guide and limit the chain, and the guide grooves slidably engage with the push plate and front stop plate, ensuring that the push plate 1111 and front stop plate remain upright as they pass through the horizontal conveyor path.

[0047] Reference Figures 6 to 8 The cardboard conveyor assembly 2 shown includes a cardboard conveyor track 23 that carries the packaging material cardboard 200 for horizontal transportation, and a cardboard conveyor drive assembly that drives the packaging material cardboard 200 along the cardboard conveyor track 23. The cardboard conveyor track 23 extends above the boxing station and intersects with the horizontal motion path of the boxing conveyor assembly. Thus, the packaging material cardboard can be conveyed along the cardboard conveyor track 23 to the top of the boxing station. The cardboard conveyor track 23 intersects with the horizontal motion path of the boxing conveyor assembly but is located above it, so it does not affect the normal transportation of the formed cartons.

[0048] Among them, the cardboard conveying drive assembly includes a cardboard conveyor belt mechanism 21 and a pressure wheel group 22. The cardboard conveyor belt mechanism 21 is provided with a cardboard conveyor belt. The cardboard conveyor belt has a horizontal conveying surface. The pressure wheel group 22 is arranged above the horizontal conveying surface. The pressure wheel group 22 presses the cardboard on the horizontal conveying surface, so that there is a large friction between the cardboard and the horizontal conveying surface, so that the cardboard conveyor belt drives the packaging cardboard to be conveyed.

[0049] Although the cardboard conveyor track 23 extends above the boxing station, the cardboard conveying drive assembly cannot fully extend above the boxing station to ensure that the packaging cardboard can fall at the boxing station. However, it is also necessary to ensure that the cardboard conveying drive assembly can fully convey the packaging cardboard to the boxing station. Therefore, the cardboard conveyor belt has been specially designed. The cardboard conveyor belt includes two main conveyor belts 211 arranged side by side and an intermediate conveyor belt 212 that extends forward from between the two main conveyor belts and protrudes from the front end of the main conveyor belts 211. The intermediate conveyor belt 212 protrudes toward the boxing station but does not extend into the space directly above the boxing station. Because it occupies a small space, it does not interfere with other components. At the same time, it can act on the rear end of the packaging cardboard to fully convey the packaging cardboard to the boxing station. After leaving the cardboard conveyor belt and before boxing, the packaging cardboard is mainly supported by the cardboard conveyor track 23 and remains flat.

[0050] Furthermore, the cardboard conveying drive assembly also includes a conveyor belt drive motor 213 and two sets of drive pulleys 214 driven by the conveyor belt drive motor 213. The two sets of drive pulleys 214 are arranged side by side and are respectively connected to the main conveyor belt 211; the main conveyor belt is also connected to at least one driven pulley 216, and the driven pulley 216 is installed on the driven pulley shaft. The intermediate conveyor belt 212 is connected to the intermediate pulley, and the intermediate pulley is installed on the intermediate pulley shaft, one of the intermediate pulley shafts and one of the driven pulley shafts are separately arranged and fixedly connected, or one of the intermediate pulley shafts and one of the driven pulley shafts are integrated, and the corresponding intermediate pulley is integrated with the driven pulley.

[0051] To facilitate the arrangement of the intermediate conveyor belts, the cardboard conveying drive assembly features an intermediate bracket 215 between the two main conveyor belts. This bracket 215 protrudes from the front of the two main conveyor belts and houses two intermediate pulley shafts: the first rotatably supported at the rear of the bracket, and the second rotatably supported at the front. The two intermediate conveyor belts are symmetrically positioned on either side of the intermediate bracket. This creates a wide conveying surface between the two main conveyor belts 211, ensuring stable cardboard transport in the rear half of the cardboard conveying track 23.

[0052] Specifically, the pressure roller assembly 22 includes two rows of pressure rollers 221 mounted side by side on a pressure roller bracket 222. A fixed bracket 223 is provided above the pressure roller bracket, and a guide sleeve is provided on the fixed bracket. The guide sleeve is connected to a guide rod 224. The lower end of the guide rod is fixed to the pressure roller bracket. An adjusting nut is provided on the fixed bracket, and the adjusting nut is connected to an adjusting screw 225. The adjusting screw is connected to the two guide rods via a connecting cross bar 226. After the adjusting nut is adjusted, the adjusting screw drives the two guide rods to rise and fall along the guide sleeve via the connecting cross bar 226, thereby adjusting the height of the two rows of pressure rollers 221. Finally, the position of the adjusting screw 225 can be locked by a locking nut. Therefore, the distance between the pressure roller 221 and the horizontal conveying surface can be adjusted, which is suitable for conveying packaging cardboard of different thicknesses.

[0053] Furthermore, a guide plate 227 is provided in front of the pinch roller bracket, which cooperates with the protruding portion of the intermediate conveyor belt 212 to guide the conveyance of the packaging cardboard. A height adjustment mechanism is connected to the guide plate 227, which is used to adjust its height to accommodate packaging cardboard of varying thicknesses. The height adjustment mechanism can refer to existing technologies, for example, similar to the height adjustment structure of the pinch roller assembly 22.

[0054] like Figure 7 As shown, the cardboard conveyor track 23 includes side rails 231 arranged side by side and a middle rail 232 located between the two side rails 231. The middle rail 232 is located to the side of the cardboard conveyor drive assembly, extending from the side of the cardboard conveyor drive assembly to above the box packing station. It corresponds to the bend of the packaging cardboard. Therefore, it cooperates with the side rails 231 to ensure that the packaging cardboard maintains a stable posture during conveyance. It also guides one side of the packaging cardboard during the packaging material forming process, so that it can be folded along the bend.

[0055] Furthermore, the lateral track 231 includes a conveying section 2311 corresponding to the horizontal conveying surface of the conveyor belt, and an output section 2312 connected to the conveying section 2311 and extending above the boxing station. The conveying section is provided with a limiting channel formed by upper and lower limiting walls and side limiting walls, which limit the upper and lower sides and sides of the edge of the packaging cardboard. Therefore, the packaging cardboard can be conveyed in a stable posture. The output section is provided with a conveying surface arranged in the direction of extension of the lower limiting wall and side retaining walls arranged in the direction of extension of the side limiting wall. The output section 2312 is provided with a positioning plate 2313 extending inward near the output end. A structure similar to the upper limiting wall is not provided above the output section because during the packaging material forming process, the edge of the packaging cardboard will flip upward, and the provision of an upper limiting wall will affect this movement process. The positioning plate 2313 prevents the packaging cardboard from continuing to be conveyed after it has been delivered to the desired position.

[0056] Reference Figure 9 The product handling component 3 shown in FIG. 1 is used to carry a product 400 from a product carrying surface 4 to the top of a packing station. The product carrying surface is horizontally disposed and located to the side of the packing station. The product handling component 3 includes a handling suction cup assembly 31, a suction cup flipping assembly 33, and a suction cup posture maintaining assembly 32. The suction cup flipping assembly 33 is equipped with a flipping arm 333. The flipping arm 333 rotates to cause the handling suction cup assembly 31 to flip, thereby carrying the product from the product carrying surface to the top of the packing station. The posture maintaining assembly 32 maintains the posture of the handling suction cup assembly 31 during the rotation of the flipping arm 333.

[0057] To achieve rotation of the flip arm 333, the suction cup flip assembly 33 is further provided with a flip drive shaft 334 connected to the flip arm, and the flip drive shaft 334 is driven by the flip drive motor 331. It is understood that a reducer 332 may also be provided, with the input shaft of the reducer 332 connected to the output shaft of the flip drive motor 331, and the output shaft of the reducer 332 connected to the flip drive shaft 334, or may be integrally provided with the flip drive shaft. Of course, the flip drive shaft may also be directly driven by the flip drive motor 331, or the motor shaft and the flip drive shaft may be integrally provided.

[0058] In one embodiment, the posture-maintaining assembly 32 includes a rotating shaft 321, which is rotatably connected to a flip arm 333. The rotating shaft drives the transport suction cup assembly to rotate during the rotation of the flip arm to maintain the posture. For example, if a product is placed horizontally on the product support surface, it will remain horizontal during transportation, which is also the state after packaging.

[0059] Furthermore, the flip drive motor 331 can also serve as the power source for rotating the rotating shaft 321. A first synchronous pulley 335 is fixed to the flip drive shaft 333, and a second synchronous pulley 322 is fixed to the rotating shaft 321. A synchronous belt 323 is connected between the first synchronous pulley 335 and the second synchronous pulley 322. This can save costs and ensure coordinated movement of the flip drive shaft 333 and the rotating shaft 321. That is, the rotation angle of the rotating shaft 321 is coordinated with the rotation angle of the flip drive shaft 333, so that the transport suction cup assembly always maintains its posture.

[0060] The transport suction cup assembly 31 includes a suction cup mounting plate 311 , on which are mounted multiple suction cups arranged in a rectangular array. The suction cup mounting plate 311 is connected to a drive bracket 312 , which is fixedly connected to a shaft connector 313 via a clamp structure. The shaft connector 313 is connected to a rotating shaft 321 .

[0061] The above description is merely a specific embodiment of the invention, but the scope of protection of the invention is not limited thereto. Those skilled in the art will understand that the invention includes, but is not limited to, the drawings and the contents described in the above specific embodiments.
