[0002] Packing boxes are common packaging consumables in industrial production. During the production process, the flat cartons or paperboards are unfolded into a usable box shape by unfolding equipment. This method can quickly unfold the paperboards. In the assembly line, it will be used in conjunction with other packaging equipment such as carton sealers and balers to form an efficient production line.

[0003] In a production line, the packaging box production equipment is usually located at the end of the production line. During the normal unfolding process, the packaging box can form a complete packaging box body. The complete and properly placed packaging box can be directly used for subsequent bagging operations.

[0018] A method for using a position adjustment component of a packaging box assembly line comprises the following steps:

[0019] Step A, debugging the detection area. For long strip packaging boxes, the movable part of the second slide rail drives the transposition plate to move horizontally to the side close to the carton specification identification component, and the two groups of laser heads arranged on the transposition plate move horizontally synchronously. There is a gap between the two groups of laser heads, and the two groups of laser heads generate two groups of detection lights.

The upward carton baffle restricts the subsequent cartons from continuously entering. When the end of the long strip package enters the detection area of ​​the laser end head, the main body of the long strip package enters the carton specification identification component, and the carton specification identification component pushes the long strip package to reset to the center. The short package enters the detection area before entering the carton specification identification component, and the carton specification identification component is pre-operated, and the pulley group rotates. Due to the opposite movement of the two sides of the pulley group, the two groups of skateboard groups can move oppositely along the first slide rail under the drive of the pulley group, and the movement interval is the same at the same time. When the two groups of skateboard groups clamp the carton, and the sliding plate pushes the carton to make it centered in the middle of the conveyor roller, the measuring head determines the stroke of the carton clamp by measuring the distance from the carton clamp to the laser reflector, thereby indirectly obtaining the specifications of the carton, determining and recording the specifications of each group of cartons, and in the direction of travel, when the carton triggers the second group of photoelectric switches, the second group of carton limit plates move down first, and the first group of carton limit plates move down after an interval of 2-5s, and repeat the above process to achieve centering and specification identification of each group of cartons.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The present invention is provided with a carton specification identification component, which includes a slide plate group and a measuring component. The measuring component cooperates with the slide plate group to move horizontally synchronously. The slide plate group pushes the carton to the middle of the conveying roller through the process of opposite horizontal movement to correspond to the packing operation in the subsequent process. The measuring component measures the diameter of the carton by measuring the activity distance of the slide plate group. When the measured diameter data is less than the rated data of the carton, it is determined that the carton is not fully opened. The incompletely opened carton is not included in the packing operation in the subsequent process, thereby realizing the identification of the carton and adapting to the production link;

[0024] 2. In the present invention, a carton limiting plate is provided, and the carton moves driven by the conveying roller. The conveying roller passes through the first group of photoelectric switches during the movement. When the first group of photoelectric switches is triggered, two groups of pneumatic push rods push the carton baffle plate upward, and the carton baffle plate moves vertically upward to the upper part of the conveying roller with the cooperation of the limiting sliding sleeve and the sliding rod. The upward-moving carton baffle plate limits the subsequent cartons from continuously entering. In the direction of travel, when the carton triggers the second group of photoelectric switches, the second group of carton limiting plates moves downward first, and the first group of carton limiting plates moves downward after an interval of several seconds, thereby realizing the centering and specification identification of each group of cartons one by one.

[0043] The slide plate group 35 includes a sliding plate 351 and a carton clamping plate 352.

[0044] The sliding plate 351 is installed between the two groups of first slide rails 34. The sliding plates 351 of the two groups of slide plates 35 are respectively connected to the two sides of the pulley group 32. The sliding direction of the sliding plate 351 is limited by the first slide rail 34. The sliding plate 351 can only slide laterally along the first slide rail 34 under the drive of the pulley group 32.

The carton baffle 63 moves vertically upward to the upper part of the conveying roller 21 with the cooperation of the limiting sleeve 61 and the slide rod 62. The upward carton baffle 63 limits the subsequent cartons from continuously entering. In the moving direction, when the carton triggers the second group of photoelectric switches 7, the second group of carton limiting plates 6 move downward first, and the first group of carton limiting plates 6 move downward after an interval of 2-5s. The above process is repeated to realize the centering and specification identification of each group of cartons.

[0052] A method for using a position adjustment component for a packaging box assembly line comprises the following steps:

[0053] For long strip packaging boxes, the movable part of the second slide rail 43 drives the transposition plate 44 to move horizontally to the side close to the carton specification identification component 3, and the two groups of laser heads 45 arranged on the transposition plate 44 move horizontally synchronously, leaving a gap between the two groups of laser heads 45, and the two groups of laser heads 45 generate two groups of detection lights, and the two groups of detection lights cooperate with the laser reflector 5 to form a detection area.

[0055] The carton moves driven by the conveyor roller 21. The conveyor roller 21 passes through the first group of photoelectric switches 7 during the movement. When the first group of photoelectric switches 7 is triggered, the two groups of pneumatic push rods 64 push the carton baffle 63 upward. The carton baffle 63 moves vertically upward to the upper part of the conveyor roller 21 with the cooperation of the limiting sliding sleeve 61 and the sliding rod 62. The upward carton baffle 63 limits the subsequent cartons from continuously entering. When the end of the long strip package enters the detection area of ​​the laser end head 45, the main body of the long strip package enters the carton specification recognition component 3. The carton specification recognition component 3 pushes the long strip package to reset in the center. The short package enters the detection area before entering the carton specification recognition component 3. The carton specification recognition component 3 is pre-operated, and the pulley group 32 rotates. Due to the pulley The opposite movement of the two sides of the group 32 allows the two groups of slide groups 35 to move in opposite directions along the first slide rail 34 driven by the pulley group 32, and the movement intervals are the same at the same time. When the two groups of slide groups 35 center the carton by clamping, and the sliding plate 351 pushes the carton to center it in the middle of the conveyor roller 21, the measuring head 361 determines the stroke of the carton clamp 352 by measuring the distance from the carton clamp 352 to the laser reflector 5, thereby indirectly obtaining the specifications of the carton, determining and recording the specifications of each group of cartons, and in the direction of travel, when the carton triggers the second group of photoelectric switches 7, the second group of carton limiting plates 6 move down first, and the first group of carton limiting plates 6 move down after an interval of 2-5s, and repeat the above process to realize the centering and specification identification of each group of cartons.

A method for using the position adjustment assembly for a packaging box assembly line according to any one of claims 1 to 9, characterized in that: The following steps are included: Step A, testing area debugging; Step A1: for a long strip packaging box, the movable part of the second slide rail drives the transposition plate to move horizontally toward the side close to the carton specification identification component, and the two groups of laser heads arranged on the transposition plate move horizontally synchronously, with a gap left between the two groups of laser heads, and the two groups of laser heads generate two groups of detection lights, and the two groups of detection lights cooperate with the laser reflector to form a detection area; Step A2: for short and small packages, the movable part of the second slide rail drives the transposition plate to move laterally to a side away from the carton specification recognition component, and the laser head arranged on the transposition plate moves laterally synchronously; Step B, feeding the packaging box; Step B1, when the chain motor is working, it drives the conveyor chain to rotate, and the rotating conveyor chain synchronously drives each group of conveyor rollers connected thereto to rotate; Step B2, placing the packaging box on a continuously rotating conveyor roller, and the conveyor roller pushes the packaging box to move in one direction; Step C, packaging box identification; Step C1, the carton moves driven by the conveyor roller, and the conveyor roller passes through the first group of photoelectric switches during the movement. When the first group of photoelectric switches is triggered, two groups of pneumatic push rods push the carton baffle upward, and the carton baffle moves vertically upward to the upper part of the conveyor roller under the cooperation of the limiting sliding sleeve and the sliding rod. The upward moving carton baffle restricts the subsequent cartons from continuously entering; Step C2, when the end of the long strip package enters the detection area of ​​the laser head, the main body of the long strip package enters the carton specification recognition component, and the carton specification recognition component pushes the long strip package to reset to the center; Step C3, the short and small package enters the detection area before entering the carton specification recognition component, and the carton specification recognition component starts pre-operation; Step C4, the pulley group rotates. Due to the opposite movement of the two sides of the pulley group, the two sets of slide plates can move oppositely along the first slide rail under the drive of the pulley group, and move at the same interval at the same time. The two sets of slide plates are clamped to center the carton; Step C5, when the sliding plate pushes the carton to make it centered in the middle of the conveying roller, the measuring head determines the stroke of the carton clamping plate by measuring the distance from the carton clamping plate to the laser reflector, thereby indirectly obtaining the specifications of the carton, and determining and recording the specifications of each group of cartons; Step C6, in the direction of travel, when the carton triggers the second group of photoelectric switches, the second group of carton limiting plates move down first, and the first group of carton limiting plates move down after an interval of 2-5 seconds. The above process is repeated to achieve centering and specification identification of each group of cartons.
