Abstract
Description
Technical Field
[0001] This application relates to the field of product packaging technology, specifically to a POS automated packaging production line. Background Technology
[0002] Packaging boxes are containers used to package, protect, and display products, and are typically made of cardboard, plastic, metal, or other materials. They come in a wide variety of types and designs to meet the packaging needs of different products.
[0003] Packaging boxes are typically flat sheets with pre-cut shapes and creases at the factory. They require folding to form the final box shape. To improve folding efficiency and reduce labor costs, the inventor has developed an automatic folding device for folding cardboard into corresponding shapes. During operation, the cardboard is manually placed into a feeding trough. A material-grabbing mechanism uses suction cups or mechanical grippers to pick up the material, then moves the box to the stamping and forming station. Under the action of a mold, the box is pressed and formed. A lifting cylinder then pushes the formed box to the folding station, completing the three-dimensional structure. This allows for engineered and mechanized folding operations, significantly saving time and improving work efficiency. It also reduces labor and time costs while ensuring the folded boxes meet the required shape and size.
[0004] In the production of packaging boxes in some manufacturing sectors, it is common to affix labels to both the inside and outside of the box. However, the aforementioned box-folding machine, to the inventor's knowledge, can only fold the box body and cannot perform labeling on both the inside and outside sides. Currently, box labeling is mainly done manually, which leads to problems such as inconsistent label placement due to operator error, resulting in misaligned or uneven labels that affect the aesthetics of the packaging box.

[0027] The programs involved or relied upon in the following embodiments are all conventional or simple programs in this technical field. Those skilled in the art can make conventional selections or adaptive adjustments according to specific application scenarios.
[0028] To better understand the technical solution of this application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0029] To address the issue that existing folding boxes cannot perform labeling operations, requiring manual labeling which leads to low production efficiency, high labor costs, and inconsistent labeling quality, this example discloses a POS automated packaging production line. (See attached image.) Figure 1 It includes a feeding and waste discharge machine 1, an inner box labeling machine 2, a box folding machine 3, and an outer box labeling machine 4, which are arranged sequentially from upstream to downstream. The materials are transferred between each mechanism by corresponding conveyor belts.
[0030] In this embodiment, taking a paper packaging box as an example, the cardboard is cut and shaped according to the corresponding contours and then enters the POS automated packaging production line for box folding and labeling operations. Specifically, the cut and creasing material board is placed at the feeding and waste removal machine, which then transports it to the POS automated packaging production line for folding and labeling. For details, see... Figure 2 In this embodiment, the feeding and waste discharge machine includes a feeding trough, into which material plates are stacked and placed to achieve feeding. In this example, the feeding trough includes a vertically arranged frame 11, the cross-sectional profile of which matches the profile of the material plate, facilitating the stacking of the material plates to be folded and labeled. Since the material plates are stacked vertically, to ensure sequential retrieval and processing in subsequent stages, the feeding and waste discharge machine 1 also includes a feeding arm 12. The feeding arm 12 moves along a guide rail fixed to the top of the feeding and waste discharge machine 1, thereby enabling the movement of the material plates after pickup. To ensure reliable pickup of the material plates by the feeding arm 12, several suction cups 121 are provided at the bottom of the feeding arm 12. These suction cups are pneumatic suction cups, controlled by an air source. The suction action of the suction cups 121 is controlled by the suction action of the suction cups 121 at the bottom of the feeding arm 12, thus achieving the purpose of picking up the material plates.
[0031] However, considering that the feeding trough needs to have a certain depth to reduce the number of times the material plates are added to the feeding trough, as the number of material plates decreases, the feeding arm needs a larger range of motion to reach deeper into the feeding trough to pick up the material plates. This will result in low feeding efficiency and an increase in the size of the feeding arm's moving mechanism. Therefore, in this embodiment, a lifting plate 13 that moves vertically along the trough frame is provided in the feeding trough. In this example, the lifting plate 13 is driven by a belt. The material plates are stacked and placed on the lifting plate 13. As the number of material plates decreases, the lifting plate 13 rises continuously, so that the top material plate is always at the top of the feeding trough, thereby reducing the movement distance of the feeding arm 12 and improving the material plate picking efficiency.
[0032] In this embodiment, considering that some scrap material may not be completely removed during the processing and cutting of the material plate, thus affecting the subsequent box folding and labeling process, a waste removal machine is used to clean the scrap material at the corner holes of the material plate. For details, see [link to documentation]. Figure 2The feeding and waste discharge machine includes a waste discharge tray 14. After the feeding arm 12 picks up the material plate, it is placed on the waste discharge tray 14. The waste discharge tray 14 is provided with dropping holes 141 at the corners or slots of the material plate. Correspondingly, the bottom of the feeding arm 12 is provided with waste discharge blocks 122 driven by a waste discharge push rod. The arrangement of the waste discharge blocks 122 at the bottom of the feeding arm 12 corresponds one-to-one with the arrangement of the dropping holes 141 at the waste discharge tray 14. In this example, the waste discharge push rod is a pneumatic push rod. Thus, after the material plate is placed on the waste discharge tray 14 by the suction cup 121 of the feeding arm 12, the waste discharge push rod extends vertically to drive the waste discharge blocks 122 to press down. The corner waste that has not completely detached is squeezed by the waste discharge blocks 122 and then passes through the corresponding dropping holes 141 to separate from the material plate and fall off. In addition, in this embodiment, in order to facilitate the collection of waste falling from the waste discharge tray, a collection chute 15 is provided below the waste discharge tray 14. Thus, the fallen waste enters the collection chute 15 and gathers. By setting a waste collection container at the outlet of the collection chute 15, waste collection can be achieved.
[0033] The box labeling machine is used to apply labels to the inside of the box. See details below. Figure 3 It includes a first conveyor belt 21. After being crushed, the waste material from the edges of the material plate is moved and conveyed by the loading arm 12 to the first conveyor belt for labeling. Because the labeling operation requires precise positioning of the material plate, otherwise problems such as misaligned labels may occur. To accurately position the material plate at the first conveyor belt 21, a positioning mechanism 22 is fixedly installed at the first conveyor belt 21 to position the material plate to the center of the conveyor belt. See [link to relevant documentation]. Figure 3The positioning mechanism 22 is set perpendicular to the running direction of the first conveyor belt 21. To adjust the position of the material plate, the positioning mechanism 22 includes a driving gear on one side of the first conveyor belt 21 and a driven gear on the other side of the first conveyor belt 21. A synchronous ring belt 221 is provided between the driving gear and the driven gear. The driving gear is driven by a synchronous motor. Two positioning blocks 222 are symmetrically fixed at the synchronous ring belt 221 about the center line of the first conveyor belt 21, and the two positioning blocks 222 are respectively located on both sides of the synchronous ring belt 221. Thus, under the power drive of the driving gear, the positioning mechanism 22 adjusts the position of the material plate. As the synchronous belt 221 rotates, the two positioning blocks 222 are symmetrically positioned on both sides of the synchronous belt. When the synchronous belt 221 rotates, the two positioning blocks 222 move synchronously to the sides or center about their symmetrical centerline, i.e., the centerline of the first conveyor belt. Therefore, before the material plate arrives, the synchronous belt is adjusted by the drive gear to maximize the distance between the two positioning blocks 222. After the material plate is placed on the first conveyor belt, the distance between the two positioning blocks 222 is reduced synchronously, pushing the edge of the material plate. This adjusts the position of the material plate so that its centerline coincides with the centerline of the first conveyor belt 21, ensuring consistency in subsequent labeling positions. Furthermore, in this embodiment, considering that the positioning blocks 222 have a certain weight, and the synchronous belt material is relatively soft and cannot guarantee the stability of the positioning blocks 222 during movement, therefore, see [reference needed]. Figure 3 The positioning mechanism also includes two guide rods 223 passing through the positioning block 222. The guide rods 223 are relatively fixed to the first conveyor belt 21, so that the positioning block moves along the guide rods 223 under the drive of the synchronous ring belt 221, ensuring the stability of its motion force and avoiding shaking and other factors that would affect the centering positioning of the material plate.
[0034] In addition, the in-box labeling machine also includes a first labeling head, which includes a feeding tray 23 storing label rolls and a receiving tray 24 for collecting the backing tape of the used label rolls. Several rollers for guiding the label rolls are provided between the feeding tray 23 and the receiving tray 24. To achieve automatic labeling on the surface of the material plate, in this embodiment, the first labeling head also includes a horizontal adjustment mechanism and a vertical adjustment mechanism. The horizontal adjustment mechanism is used to adjust the position of the first labeling head in the horizontal direction perpendicular to the running direction of the first conveyor belt. The vertical adjustment mechanism is used to move the first labeling head up and down in the vertical direction, thereby realizing the adjustment of the labeling position and the labeling action. For separating the label from the backing tape at the label roll, see [link to documentation]. Figure 3The first labeling head also includes a peeling plate 25. The back of the label roll is in contact with the end of the peeling plate 25. As the feeding tray 23 and the receiving tray 24 roll, the label roll moves along the rollers and the peeling plate 25. Since the label roll bends and changes direction at the peeling plate 25, and the label is thicker than the backing tape, the label opens and separates from the backing tape as it moves along the peeling plate 25. At this time, the first labeling mechanism is pressed down, so that the end of the label contacts the material plate, thus realizing the labeling operation. In this embodiment, to ensure flatness and complete adhesion to the material plate surface after labeling, the first labeling head also includes a first conveyor belt with its movement direction set on the end side of the peeling plate 25 for pressing and rolling the sponge roller 26 with the label already applied. In addition, the in-box labeling machine also includes a first position sensor to detect the position of the material plate. In this example, the first position sensor is a photoelectric sensor, which drives the first labeling head to perform the corresponding labeling action after detecting that the material plate has moved into position.
[0035] After the inner labels are affixed, the folding machine folds the material board according to the corresponding creases. See below. Figure 1 The folding box machine 3 is connected to the end of the first conveyor belt of the box labeling machine, see [link / reference]. Figure 4 It includes a picking arm 31 for picking up a plate from the first conveyor belt. See also... Figure 5 The folding machine 3 also includes several guide plates 32, which are respectively located at the positions of the material plate to be folded. An extrusion arm 33 is provided along the top guide rail of the folding machine 3. The material plate picked up by the picking arm 31 is placed on the top of the guide plate 32, and then the extrusion arm 33 presses down vertically at the position of the bottom of the packaging box corresponding to the material plate. Under the action of the guide plate 32, the corresponding surface of the material plate is folded along its indentation. In this example, the top of the guide plate 32 is outwardly flared, which plays a guiding role for the material plate and avoids wear and scratches between the material plate and the guide plate 32 during the pressing process. Furthermore, in this example, a box frame 34 that can move along the conveying direction of the first conveyor belt is provided below the guide plates 32 that correspond to the side walls of the packaging box on both sides of the folding material plate. This box frame matches the bottom contour of the packaging box. Thus, after the material plate is squeezed by the extrusion arm 33, it falls into the box frame 34 and is transported to the depressor arm 35 through the box frame 34. To ensure the stability of the packaging box body, the side plates folded up by the two guide plates 32 need to be bent into the box body again to form the two side walls of the box body. For this purpose, see [reference needed]. Figure 5The semi-finished product with its side panels erected is conveyed by the box frame 34 to directly below the tongue-pressing arm 35. Then, it is pushed towards the center simultaneously by the folding components 36 on both sides, achieving further bending of the side panels. The tongue-pressing arm 35 then lowers, causing the further bent panel to bend inwards and be positioned within the box. In this example, the end of the further bent panel has a flange, and the corresponding position on the box body has a slot. Under the pressing action of the tongue-pressing arm 35, the flange at the end of the panel bends and simultaneously engages with the slot at the bottom of the box body, completing the folding assembly of the box wall. Similarly, through the pushing of the folding components 36 on both sides and the downward pressure of the tongue-pressing arm 35, the folding ears on both sides of the box lid can be folded and closed. It is then further conveyed to the external labeling machine for labeling.
[0036] See Figure 6 In this embodiment, the box labeling machine includes a second conveyor belt 41 connected to the tail of the box folding machine, used to receive and convey the folded packaging box to the second labeling head 42 for labeling. Similar to the first labeling head, the second labeling head also includes a feeding tray, a receiving tray, and a peeling plate. To ensure the accuracy of the labeling position, see [reference needed]. Figure 6 In this example, the conveyor belt is equipped with a guide groove 43 for limiting the top surface of the box and its direction and position of movement. The height of the groove 43 matches the height of the packaging box. This allows the packaging box to move along the guide groove 43 while preventing the box lid from tilting up. Additionally, a packaging box positioning component is provided at the labeling position of the second labeling head 42, see [link to documentation]. Figure 6 The packaging box positioning assembly includes a limiting plate 45 that moves vertically along the direction perpendicular to the second conveyor belt 41 and is located on one side of the guide groove 43. The limiting plate protrudes from the guide groove 43 as needed to limit the positioning of the packaging box, preventing it from moving further with the second conveyor belt 41 and stopping it at the labeling station. Furthermore, to prevent relative movement of the packaging box and ensure the accuracy of the labeling position, in this embodiment, the packaging box positioning assembly also includes a suction cup box 44 located on the other side of the guide groove 43, which adheres to the side of the packaging box to ensure its stable position. Additionally, in this embodiment, to detect the position of the packaging box, the external labeling machine also includes a second position sensor; in this example, the second position sensor is a photoelectric sensor.
