[0002] In existing technology, cartons are clamped between a pair of left and right conveyor belts and conveyed along their conveyor paths. However, as the carton is fed between the left and right conveyor belts, the shape of the carton becomes unstable due to the force applied. This can cause the carton to skew when the bottom is opened and sealed, commonly known in the industry as the "carton scissor gap." Applying tape to a skewed carton can affect its appearance. Furthermore, if the carton is skewed significantly, the edges of the seal may lift upward, or the tape wrapped around the front and back of the carton may warp or break, resulting in a less stable seal.

[0003] Therefore, there is an urgent need for a carton conveying device to solve the problem of carton skew during conveyance. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 3 The embodiment of the present invention provides a carton filling system and a carton conveying device 1. The carton filling system may include, for example, a carton conveying device 1, a carton opening device 2, and a carton sealing device 3. The carton opening device 2 is arranged on one side of the carton conveying device 1. The carton opening device 2 is used to open the carton 30 and fold the outer flap. The carton conveying device 1 clamps the carton 30 for conveying. The carton sealing device 3 is arranged on the lower side of the carton conveying device 1 to stick an adhesive tape on the bottom of the carton 30.

[0027] The carton conveying device 1 provided in the embodiment of the present invention may include, for example, a conveying mechanism 10 and a correction mechanism 20. Figure 2 and Figure 3 The conveying mechanism 10 may, for example, include a first conveyor belt 110 and a second conveyor belt 120. The first conveyor belt 110 and the second conveyor belt 120 are arranged opposite to each other and in parallel. A conveying channel 130 is formed between the first conveyor belt 110 and the second conveyor belt 120. The conveying channel 130 is used to convey the cartons 30 along a first direction. The first direction may, for example, be the longitudinal direction of the conveying mechanism 10. The first conveyor belt 110 and the second conveyor belt 120 clamp the cartons 30 on the conveying channel 130, and the cartons 30 are conveyed by the movement of the first conveyor belt 110 and the second conveyor belt 120.

[0028] The correction mechanism 20 can be, for example, disposed on one side of the transmission mechanism 10. The correction mechanism 20 includes a drive assembly 300 and a shaping plate 200, wherein the drive assembly 300 is connected to the shaping plate 200. The drive assembly 300 is used to drive the shaping plate 200 to extend into or out of the conveying channel 130. When the shaping plate 200 extends into the conveying channel 130, it is used to block the carton 30. The blocking of the carton 30 by the shaping plate 200 causes the carton 30 to be shaped by the friction between the first conveyor belt 110 and the second conveyor belt 120 and the carton 30 under the inertia of the forward movement, thereby resolving the problem of carton skew that occurs during the process of unpacking and bottom sealing the carton 30.

[0029] In the embodiment of the present invention, a conveying mechanism 10 and a correcting mechanism 20 are provided. The conveying mechanism 10 conveys the carton 30 through the conveying channel 130 between the first conveyor belt 110 and the second conveyor belt 120. The correcting mechanism 20 is provided on one side of the conveying mechanism 10, and the correcting mechanism 20 drives the shaping plate 200 to extend into or out of the conveying channel 130 through the driving component 300. The shaping plate 200 extends into the conveying channel 130 to block the carton 30, so that the carton 30 is shaped under the inertia of the forward movement. This can effectively solve the problem of carton skewness that occurs during the process of unpacking and bottom sealing the carton 30, reduce the difficulty of debugging the unpacking and bottom sealing, save debugging time, and improve the qualified rate of the carton bottom sealing.

[0030] In one implementation of this embodiment, Figure 3 As shown, the shaping plate 200 is in an extended state, and the shaping plate 200 is extended toward the conveying channel 130 and along a second direction perpendicular to the first direction. Figure 4 As shown, when the shaping plate 200 is in the extended state, the shaping plate 200 extends toward the first direction. The portion of the shaping plate 200 that extends into the conveying channel 130 may be, for example, a strip structure, and the surface of the shaping plate 200 that contacts the carton 30 is a smooth plane to avoid damage to the carton 30. In the present embodiment, the motion trajectory of the shaping plate 200 is an arc, that is, during the switching process of the shaping plate 200 from the extended state to the extended state, the shaping plate 200 is opened or closed in an arc-shaped motion estimate. When the shaping plate 200 is opened in an arc-shaped estimate, the carton 30 and the shaping plate 200 can gradually change from blocking to contact, and then gradually move from contact to the extended state, that is, the shaping plate 200 is out of contact with the carton 30, which can avoid affecting the conveying of the carton 30 or damaging the carton 30 due to excessive movement.

[0031] See also Figure 2 、 Figure 5 and Figure 6 The correction mechanism 20 may, for example, further include a fixed base 400, with the drive assembly 300 disposed on the fixed base 400. The carton conveying device 1 also includes a sensor switch 40 and a controller 50. The sensor switch 40 is disposed at one end of the fixed base 400 near the shaping plate 200. The sensor switch 40 and the drive assembly 300 are electrically connected to the controller 50. The sensor switch 40 may, for example, be a photoelectric sensor switch, specifically a photoelectric proximity switch. The controller 50 may, for example, be a PLC (Programmable Logic Controller), a microcontroller unit (MCU), or the like.

[0032] The sensor switch 40 is disposed on the fixing base 400 and is disposed near the shaping plate 200. The sensor switch 40 may, for example, have a delay function. The sensor switch 40 is used to detect when the carton 30 arrives at the correction mechanism 20 and send an opening instruction to the controller 50 according to a preset delay time. The controller 50 is used to control the driving assembly 300 to open the shaping plate 200 according to the opening instruction. For example, the carton 30 is conveyed in a first direction under the clamping of the first conveyor belt 110 and the second conveyor belt 120. When the carton 30 is conveyed to the position of the shaping plate 200, the sensor switch 40 detects that the carton 30 has reached the position of the correction mechanism 20. Through the delay function of the sensor switch, the controller 50 controls the shaping plate 200 to open, so that when the carton 30 is conveyed to the shaping plate 200, the shaping plate 200 blocks the carton 30 to complete the shaping of the carton 30. The controller 50 controls the shaping plate 200 to open after blocking, and the carton 30 continues to be conveyed.

[0033] In one embodiment of this invention, the conveying speed of the conveyor mechanism 10 is equal to or greater than the opening speed of the shaping plate 200. Specifically, the difference between the conveying speed of the conveyor mechanism 10 and the opening speed of the shaping plate 200 is 0 to 0.2 m / s. For example, the conveying speed of the conveyor mechanism 10 may be 0.6 m / s, and the opening speed of the shaping plate 200 may be 0.4 to 0.6 m / s. This configuration allows the carton 30 to move with the shaping plate 200, ensuring that the carton 30 enters the next workstation with its appearance restored.

[0034] See also Figure 5 and Figure 6 The drive assembly 300 may, for example, include a guide rod 310, a drive member 320, a sliding member 330, and a follower 340. The guide rod 310 is fixedly connected to the fixed base 400, and the sliding member 330 is disposed on the guide rod 310. The guide rod 310 may, for example, be a rod-shaped structure, and the sliding member 330 may, for example, be a slider. The sliding member 330 is provided with a through hole and is disposed on the guide rod 310. The follower 340 has one end connected to the sliding member 330 and the other end connected to the shaping plate 200. The follower 340 may, for example, be a cam follower. The driving member 320 can be, for example, a pneumatic cylinder. The driving member 320 is fixedly connected to the guide rod 310 and connected to the sliding member 330. The driving member 320 is configured to drive the sliding member 330 to reciprocate along the guide rod 310 in a first direction, while simultaneously causing the follower 340 to drive the shaping plate 200 along a motion trajectory into or out of the conveying channel 130. The driving member 320 can drive the sliding member 330 to reciprocate along a linear path along the guide rod 310. The follower 340 converts the linear motion of the sliding member 330 into circular motion, thereby driving the shaping plate 200 to move in a circular motion into or out of the conveying channel 130. The driving member 320 can be provided with, for example, a solenoid valve 321. The controller 50 is electrically connected to the solenoid valve 321. The controller 50 controls the movement of the pneumatic cylinder by controlling the solenoid valve 321, thereby controlling the opening or closing of the shaping plate 200.

[0035] The drive assembly 300 also includes an adjustment member 350, which is connected to the drive member 320. The adjustment member 350 can be, for example, a regulating valve. The adjustment member 350 is used to control the operating speed of the shaping plate 200. The adjustment member 350 can adjust the operating speed of the drive member 320. By controlling the operating speed of the drive member 320, the operating speed of the shaping plate 200 can be controlled. By adjusting the operating speed of the shaping plate 200, the operating speed of the shaping plate 200 can be matched with the conveying speed of the conveying mechanism 10.

[0036] In one embodiment of this embodiment, there may be one straightening mechanism 20, for example, which may be located on one side of the first conveyor belt 110 or on one side of the second conveyor belt 120. The length of the shaping plate 200 may be, for example, greater than half the width of the carton 30 or may be equal to the width of the carton 30, thereby better shaping the carton 30. In another embodiment of this embodiment, there may be two straightening mechanisms 20, for example, which may be located on opposite sides of the conveyor mechanism 10. The two shaping plates 200 block the carton 30 on both sides, thereby better shaping the carton 30.

[0037] See also Figure 1 The carton whole-box system may, for example, include a carton conveying device 1, a carton opening device 2, and a carton sealing device 3. The carton whole-box system may, for example, further include a support base 11, on which the carton conveying device 1, the carton opening device 2, and the carton sealing device 3 are arranged. The carton opening device 2 is arranged on one side of the carton conveying device 1, and is used to open the carton 30 and fold the outer flap. The carton conveying device 1 clamps the carton 30 for conveying, and corrects the carton 30 during the conveying process. The carton sealing device 3 is arranged on the lower side of the carton conveying device 1, and may specifically be arranged on the lower side of the conveying channel 130, for example. During the conveying process of the carton 30, an adhesive tape is affixed to the bottom of the carton 30, which can effectively solve the problem of carton skewness during the process of unpacking and bottom sealing of the carton 30, reduce the difficulty of debugging the unpacking and bottom sealing, save debugging time, and improve the qualified rate of the carton bottom sealing.
