[0002] Traditional warehouse bagging is labor-intensive, requiring only simple movements that can easily fatigue workers. Furthermore, the need to use tools (such as utility knives) to carton-splitting poses potential safety risks. Currently, automated carton-splitting equipment is being used to replace manual labor.

[0003] Current carton-cutting equipment often uses cylinders to position cartons. However, because the cylinders cannot be adjusted steplessly for cartons of different sizes, they can only achieve a "force balance" state. During actual use, unexpected situations such as cartons being "flattened" may occur.

[0004] The above content is only used to assist in understanding the technical solution of this application and does not constitute an admission that the above content is prior art. Summary of the Invention

[0008] Refer to the three-dimensional dimensions of the carton to be cut and use the servo motor to clamp the carton to be cut;

[0014] In one embodiment, the step of measuring and obtaining the three-dimensional dimensions of the carton to be marked includes:

[0015] If the difference between the three-dimensional dimensions of two adjacent cartons to be marked is greater than a preset size threshold, the three-dimensional dimensions of the cartons to be marked are measured a second time after the cartons to be marked are moved slightly.

[0016] In one embodiment, the step of clamping the carton to be scored using a servo motor with reference to the three-dimensional dimensions of the carton to be scored comprises:

[0017] Referring to the three-dimensional dimensions of the carton to be cut, the distance at which the servo motor rapidly approaches the carton to be cut and the gap between the servo motor and the carton to be cut are obtained;

[0018] During a first movement of the servo motor based on the distance, the servo motor is quickly brought close to the carton to be scribed;

[0019] During the second movement of the servo motor based on the gap, the servo motor is slowly moved closer to the carton to be scribed until the clamping mechanism safely applies force to the carton to be scribed.

[0020] In one embodiment, the step of clamping the carton to be scored using a servo motor with reference to the three-dimensional dimensions of the carton to be scored comprises:

[0023] Determine the real-time intrusion distance of the carton based on the actual running distance of the servo motor and the three-dimensional size of the carton to be cut;

[0024] If the real-time intrusion distance of the carton is greater than or equal to the preset safe deformation distance allowed to intrude into the carton, the carton to be cut will be stopped from being clamped.

[0025] In one embodiment, the step of delivering the carton to be cut in the clamped state to a preset cutting position for cutting includes:

[0026] If, during the process of delivering the carton to be cut in the clamped state to the preset cutting position for cutting, it is determined that there is a jam in the carton to be cut, the carton to be cut is clamped again based on the preset safe deformation distance allowed to intrude into the carton;

[0027] If it is determined after the second clamping that there are still stuck cartons to be cut, the cartons to be cut will be discharged before being sent to the preset cutting position for cutting.

[0028] In addition, to achieve the above-mentioned purpose, the present application also proposes a box-striping device, which includes:

[0050] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0051] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device or a computer that can perform the above functions. The following uses a computer computer as an example to illustrate this embodiment and the following embodiments.

[0052] Based on this, the embodiment of the present application provides a box-marking method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the box-dividing method of the present application.

[0053] In this embodiment, the box marking method includes steps S10 to S30:

[0054] Step S10, measuring and obtaining the three-dimensional dimensions of the carton to be cut;

[0055] In this embodiment, a TOF rangefinder is used. The selected rangefinder has high anti-interference performance and can be used for measuring the distance of cartons with common surface attachments such as transparent tape and label paper.

[0056] In a feasible implementation manner, step S10 includes:

[0057] Obtaining reference position data measured at a preset measurement position of the carton to be marked;

[0058] Collecting actual position data of the carton to be marked obtained by actual measurement at the preset measurement position;

[0059] The three-dimensional size of the carton to be marked is calculated based on the reference position data and the actual position data.

[0060] In one embodiment, referring to Figure 2 When a carton passes through the "pre-centering + measurement" position, the centering clamping cylinder pushes the carton to the center of the unit and immediately stops applying force to prevent "flattening" of soft materials, underfilled cartons, or cartons without strong support. Distance meters 1 and 2 respectively capture the carton's height and width. When a carton passes through the "side seam push" unit, distance meter 3, driven by the servo / swing cylinder, swings to the side of the carton to capture its length.

[0061] In one embodiment, referring to Figure 3 , Figure 3 This is a schematic diagram of measuring the width of the carton to be marked. Figure 4 , Figure 4 It is a schematic diagram of the height and length measurement of the carton to be marked. L1 is the reference position data measured at the preset measurement position of the carton to be marked, which can be the distance data from the "rangefinder installation position" to the "fixed reference position" pre-entered through the touch screen. L2 is the actual position data of the carton to be marked actually measured at the preset measurement position, that is, the distance data measured by the rangefinder. L=L1-L2 is the three-dimensional size data of the carton to be marked.

[0062] In this way, all cartons within the allowable range of the mechanical mechanism's travel can be automatically "adapted". After the machine is adjusted once, there is no need for manual adjustment for different cartons.

[0063] In a feasible implementation manner, step S10 includes:

[0064] If the difference between the three-dimensional dimensions of two adjacent cartons to be marked is greater than a preset size threshold, the three-dimensional dimensions of the cartons to be marked are measured a second time after the cartons to be marked are moved slightly.

[0065] In one embodiment, if the three-dimensional size data measured between two adjacent cartons to be marked differ too much and exceed a preset size threshold, the roller will move the cartons to be marked slightly and then perform a second measurement to ensure the accuracy of the measurement data.

[0066] Step S20, referring to the three-dimensional dimensions of the carton to be cut, using a servo motor to clamp the carton to be cut;

[0067] After accurately positioning the three-dimensional dimensions of the carton to be cut, a servo motor can be used to clamp the carton to be cut. Therefore, when processing cartons of different sizes and hardness, the carton cutting equipment must be able to automatically "adapt" to the carton, and by automatically measuring the carton size, the servo motor can achieve "safe positioning" of the carton.

[0068] It should be noted that the motor clamping mode is "stationary position" and the cylinder clamping mode is "force balance". During the movement of the carton, the surface stress will change due to the influence of blade resistance and belt friction. At this time, the force balance of the cylinder clamping will be destroyed, which may cause the carton to be "flattened" and damage the products in the box. Motor clamping can avoid this situation.

[0069] In a feasible implementation manner, step S20 includes:

[0070] Referring to the three-dimensional dimensions of the carton to be cut, the distance at which the servo motor rapidly approaches the carton to be cut and the gap between the servo motor and the carton to be cut are obtained;

[0071] During a first movement of the servo motor based on the distance, the servo motor is quickly brought close to the carton to be scribed;

[0072] During the second movement of the servo motor based on the gap, the servo motor is slowly moved closer to the carton to be scribed until the clamping mechanism safely applies force to the carton to be scribed.

[0073] In one embodiment, referring to Figure 5 , Figure 5 The X-axis position of the middle seam is shown in Figure 2. Figure 6 , Figure 6The diagram below shows the position of the center seam Z axis and the side seam X / Z axis. L is the distance that the servo motor quickly approaches the carton to be marked. L1 is the reference position data measured at the preset measurement position of the carton to be marked. It is the distance between the motor origin and the fixed reference object pre-entered according to the actual assembly of the machine. L2 is the gap between the servo motor and the carton to be marked after the servo motor quickly approaches the carton to be marked (which can be set according to the actual scene through the touch screen). L3 is the three-dimensional size of the carton to be marked obtained above. When the carton flows out of the front unit, the motor drives the clamping mechanism to move at high speed for a distance of L (L=L1-L2-L3). At this time, due to the gap L2, the carton can smoothly enter the "clamping mechanism". The motor clamping mechanism is equipped with a micro switch. When the carton reaches the carton cutting position, the motor moves at low speed. When the micro switches on both sides of the X-axis (one side of the Z-axis) of the clamping mechanism are triggered, it proves that the clamping mechanism has safely applied force to the carton surface. The motor stops moving, and the carton is pushed forward by the belt, and the center seam / side seam is cut open.

[0074] In this embodiment, the dimensions of the carton are measured in advance and calculated to control the multi-stage movement of the servo motor, thereby achieving safe and accurate positioning and clamping of the carton.

[0075] In a feasible implementation manner, step S20 includes:

[0076] Monitor the real-time position of the clamping mechanism;

[0077] Determine the actual running distance of the servo motor based on the real-time position of the clamping mechanism;

[0078] Determine the real-time intrusion distance of the carton based on the actual running distance of the servo motor and the three-dimensional size of the carton to be cut;

[0079] If the real-time intrusion distance of the carton is greater than or equal to the preset safe deformation distance allowed to intrude into the carton, the carton to be cut will be stopped from being clamped.

[0080] In one embodiment, referring to Figure 7 , Figure 7 To prevent over-clamping, the clamping mechanism is powered by a servo motor, which features precise closed-loop control. This allows accurate monitoring of the clamping mechanism's real-time position. L represents the calculated distance between the motor's origin and the carton surface, and L1 represents the permissible distance of intrusion into the carton (which must be less than the generally accepted safe deformation of the carton). If the clamping mechanism's microswitch is damaged or other special circumstances occur, and the motor travels a distance (L + L1) without receiving a stop signal, the machine will immediately shut down and issue an alarm to prevent the carton from being clamped and damaged, potentially affecting the contents.

[0081] Step S30: The carton to be cut in the clamped state is sent to a preset cutting position for cutting.

[0082] In a feasible implementation manner, step S30 includes:

[0083] If, during the process of delivering the carton to be cut in the clamped state to the preset cutting position for cutting, it is determined that there is a jam in the carton to be cut, the carton to be cut is clamped again based on the preset safe deformation distance allowed to intrude into the carton;

[0084] If it is determined after the second clamping that there are still stuck cartons to be cut, the cartons to be cut will be discharged before being sent to the preset cutting position for cutting.

[0085] If cartons soften due to repeated use or if the material itself is too soft, the resistance of the blades when cutting the cartons may be greater than the driving force of the belt, causing the cartons to jam. The program automatically determines whether a carton is jammed based on the unit's normal rhythm and whether the cartons are actually flowing out. When a carton jam is detected, the X-axis and Z-axis apply a secondary, appropriate amount of pressure to the carton (the amount of movement can be pre-set on the touch screen based on the scenario; the sum of the movement and the aforementioned intrusion distance must be less than the carton's safe deformation), thereby providing greater friction to drive the carton forward.

[0086] In rare cases, if the carton is still stuck after the second compression, the drive mechanism will retract the blade and simultaneously open an appropriate gap between the X-axis and Z-axis to allow the carton to flow out. This avoids the need for manual entry into the equipment's working area to handle anomalies when the carton is stuck, maximizing equipment utilization while ensuring personal safety.

[0087] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the box-drawing method of the present application.
