Description

Technical Field

[0001] This utility model relates to the field of cartoning machine technology, and in particular to a medicine box positioning and error prevention device for a cartoning machine. Background Technology

[0002] Cartoning machines are automated devices widely used in pharmaceuticals, food, cosmetics, and other industrial fields. They are primarily used to automatically fill products into cartons and seal them. Cartoning machines can be customized to meet different product characteristics and packaging requirements, including but not limited to blister packaging for pharmaceuticals and cartoning for bottled or bagged foods. Their working principle typically involves steps such as product feeding, instruction manual insertion, carton forming, product filling, and carton sealing.

[0003] In the pharmaceutical production and packaging process, cartoning machines are responsible for automatically loading the medicine and its instructions into boxes and sealing them. However, on high-speed production lines, boxes may become misaligned, misoriented, or fail to enter the designated track. This can lead to cartoning failure, production line downtime, increased production costs, and, more seriously, serious quality and safety hazards if incorrectly cartoned medicines enter the market.

[0004] Therefore, it is necessary to design a box positioning and error prevention device for a cartoning machine to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of cartoning machines in pharmaceutical packaging, which are responsible for filling and sealing medicines and instructions into boxes, but which are prone to positional deviation, incorrect orientation, or failure to enter the correct track on high-speed production lines, leading to cartoning failure, machine downtime, increased costs, and even potential quality and safety hazards, this utility model provides a box positioning and error prevention device for cartoning machines.

[0006] A box positioning and error prevention device for a cartoning machine includes a support frame, a control panel, a warning light, a connecting frame, a vision sensor, a mounting plate, and a laser scanner. Each of the two support frames has symmetrically distributed mounting holes on one side. The control panel is fixedly connected to the left side of one of the support frames, and a warning light is fixedly connected to the top of the control panel. A connecting frame is fixedly connected between the tops of the two support frames. A vision sensor is fixedly connected through the middle of the connecting frame and electrically connected to the control panel. Mounting plates are fixedly connected to both sides of the connecting frame, and laser scanners are fixedly connected to the bottom of each of the two mounting plates. Both laser scanners are electrically connected to the control panel.

[0007] Further explanation: It also includes a fixed rod, a motor, a bidirectional screw, a guide rod, and an adjusting plate. Fixed rods are fixedly connected to one side of each of the two support frames. A motor is fixedly connected to the left side of one of the fixed rods. The output shaft of the motor passes through one of the fixed rods and is fixedly connected to the bidirectional screw. The bidirectional screw is rotatably connected between one side of the two fixed rods. A guide rod is fixedly connected between the other side of the two fixed rods. Adjusting plates are symmetrically connected between the guide rod and the bidirectional screw. One side of each adjusting plate is slidably connected to the guide rod, and the other side of each adjusting plate is threadedly connected to the bidirectional screw.

[0008] To elaborate further, the two adjustment plates are located between the vision sensors.

[0009] To further explain, it also includes a fixed shell and rollers. The fixed shell is fixedly connected to one side of each of the two adjustment plates, and multiple rollers are linearly arrayed and rotated on one side of each of the two fixed shells.

[0010] To further explain, it also includes a lamp holder, a lamp tube, and a diffuser plate. The lamp holder is fixedly connected to the bottom of the connecting frame, the lamp tube is fixedly connected inside the lamp holder, the lamp tube is electrically connected to the control panel, and the diffuser plate is fixedly connected to the bottom of the lamp holder.

[0011] To further explain, the lamp holder has a circular structure, with its axis being the mounting position of the vision sensor.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model uses a visual sensor combined with an image recognition algorithm to accurately determine whether the medicine box exists, whether its orientation is correct, and whether it is damaged, tilted, or overlapped; the laser scanner non-contactly detects the height, width, and position of the medicine box to ensure size matching. The two sets of data are transmitted to the control screen in real time for fusion analysis. If an abnormality is found, an alarm light is immediately triggered, and specific error information is displayed on the control screen to prompt the operator to handle it in time. This realizes comprehensive monitoring of the positioning status of the medicine box and effectively prevents mis-packing and omission.

[0013] 2. This utility model achieves accurate identification of the positional deviation of the medicine box through the coordinated detection of a visual sensor and a laser scanner. The control panel drives the bidirectional screw to rotate, which drives the two adjustment plates on both sides to move synchronously towards or away from each other, completing the automatic centering calibration of the medicine box. The adjustment plates move smoothly under the guidance of the guide rod and the sliding guide sleeve, ensuring that the calibration action is accurate and reliable, avoiding positioning deviation caused by mechanical shaking, realizing automatic correction of medicine box positioning errors, reducing manual intervention, and improving the boxing efficiency and operational stability.

[0014] 3. When the medicine box is calibrated by adjusting the plate, the medicine box enters the guide channel formed between the two roller rows. The roller surface contacts the side of the medicine box and rotates with its movement, converting sliding friction into rolling friction, which significantly reduces the conveying resistance and effectively prevents the medicine box from getting stuck during movement. At the same time, the roller rows apply a guiding force to the medicine box with slight lateral deviation during rotation, achieving automatic alignment without hindering its forward movement, and improving the consistency of the medicine box's posture when entering the detection area.

[0015] 4. This utility model sets up a ring-shaped lamp holder below the vision sensor and installs a diffuser plate at the bottom of the lamp holder. This allows the light emitted by the lamp tube to be evenly diffused by the diffuser plate and then illuminate the surface of the medicine box, forming a soft and uniform surface light source. The surround lighting structure provides synchronous illumination from multiple directions, effectively avoiding the shadow and reflection problems caused by traditional single-sided light sources. This significantly improves the image acquisition quality of the vision sensor in complex environments. Under uniform lighting conditions, the image contrast is higher and the edge details are clearer, greatly enhancing the system's accuracy in recognizing the direction, damage, and overlap of the medicine box.

Detailed Implementation

[0022] Example: A box positioning and error prevention device for a cartoning machine, such as... Figures 1-5As shown, the system includes a support frame 1, a control panel 2, a warning light 3, a connecting frame 4, a vision sensor 5, a mounting plate 6, and a laser scanner 7. The two support frames 1 have symmetrically distributed mounting holes 101 on their opposite sides. The control panel 2 is mounted on the left side of the left support frame 1 with screws. The warning light 3 is mounted on the top rear side of the control panel 2 with screws. The connecting frame 4 is mounted between the tops of the two support frames 1 with screws. A vision sensor 5 is mounted through the middle of the connecting frame 4 with screws. The vision sensor 5 is electrically connected to the control panel 2. Mounting plates 6 are mounted on both the front and rear sides of the connecting frame 4 with screws. Laser scanners 7 are mounted on the bottom of both mounting plates 6 with screws. Both laser scanners 7 are electrically connected to the control panel 2.

[0023] Two support frames 1 are symmetrically arranged on both sides above the cartoning machine. They are securely fixed with bolts or quick-release mechanisms through mounting holes 101. A connecting frame 4 spans the top of the two support frames 1, serving as the mounting platform for the core detection component. The control panel 2 is convenient for operators to view and operate. Warning lights 3 are used for abnormal indication. The vision sensor 5 is vertically downward facing the medicine box conveying path. When the medicine box passes below, the vision sensor 5 captures its image and uses an image recognition algorithm to determine whether the orientation is correct, whether there is damage, tilting, overlapping, or other abnormalities. The detection results are transmitted to the control panel 2 in real time, where the system within the control panel 2 makes judgments and processes them. The laser scanner 7 uses a non-contact scanning method to continuously measure the height, width, and surface contour of the medicine box. It can accurately identify whether the medicine box has completely entered the detection area, whether there has been any offset, stacking, or flipping, and whether there are any size discrepancies. The data is also fed back to the control panel 2 and fused with the data from the vision sensor 5 for analysis. The control panel 2 receives dual data from the vision sensor 5 and the laser scanner 7 and performs comprehensive analysis. If the medicine box is in the correct position, orientation, and size, the subsequent boxing process continues. If an incorrect orientation, missing, stacked, or off-track medicine box is detected, the alarm light 3 will flash, and the specific error information will be displayed on the control panel 2. The operator can intervene in time according to the prompts on the control panel 2 to adjust the position of the medicine box or clear the abnormality. After the problem is resolved, the system can be manually reset through the control panel 2 to restore automatic operation.

[0024] like Figure 1 and Figure 3As shown, it also includes a fixed rod 8, a motor 9, a bidirectional screw 10, a guide rod 11, and an adjustment plate 12. The fixed rod 8 is installed on the side of the two support frames 1 that are far apart from each other by screws. The motor 9 is installed on the left side of the fixed rod 8 on the front side by screws. The output shaft of the motor 9 passes through the fixed rod 8 on the left side and is welded to the bidirectional screw 10. The bidirectional screw 10 is rotatably connected between the front sides of the two fixed rods 8. The guide rod 11 is welded between the rear sides of the two fixed rods 8. The adjustment plate 12 is symmetrically connected between the guide rod 11 and the bidirectional screw 10. The rear sides of the two adjustment plates 12 are slidably connected to the guide rod 11. The front sides of the two adjustment plates 12 are threadedly connected to the bidirectional screw 10. The two adjustment plates 12 are located between the vision sensors 5.

[0025] If the vision sensor 5 and the laser scanner 7 detect a misalignment in the placement of the medicine box, the motor 9 can be started via the control panel 2. Its output shaft drives the bidirectional screw 10 to rotate clockwise. Since the bidirectional screw 10 has a left-right thread structure, when it rotates, the adjustment plates 12 on both sides will move synchronously in opposite directions along the screw. The adjustment plates 12 push the medicine box to center and calibrate it. After calibration, the output shaft of the motor 9 reverses, and the adjustment plates 12 on both sides move synchronously in opposite directions along the guide rod 11 to detach from the medicine box. One side of each adjustment plate 12 is engaged with the guide rod 11 through a sliding guide sleeve to ensure that its movement trajectory is stable and without shaking.

[0026] like Figure 1 and Figure 4 As shown, it also includes a fixed shell 13 and rollers 14. The fixed shell 13 is welded to the side of the two adjusting plates 12 that are close to each other. Multiple rollers 14 are linearly arrayed and rotated on the side of the two fixed shells 13 that are close to each other.

[0027] The medicine box enters the channel formed between two rows of rollers 14 during calibration via the adjustment plate 12. The surface of the rollers 14 contacts the side of the medicine box and rotates under their influence. Since rolling friction replaces sliding friction, the resistance during the movement of the medicine box is greatly reduced, preventing jamming. If the medicine box has a slight lateral deviation before entering the detection area, the rows of rollers 14 can apply a certain guiding force to it. Since the rollers 14 have the ability to rotate, they will not obstruct the medicine box, but will instead play a role in straightening it.

[0028] like Figure 5 As shown, it also includes a lamp holder 15, a lamp tube 16 and a diffuser plate 17. The lamp holder 15 is installed at the bottom of the connecting bracket 4 by screws. The lamp tube 16 is installed inside the lamp holder 15 by screws. The lamp tube 16 is electrically connected to the control panel 2. The diffuser plate 17 is welded to the bottom of the lamp holder 15. The lamp holder 15 has a circular structure, and its axis is the installation position of the vision sensor 5.

[0029] When the medicine box enters below the vision sensor 5, the control screen 2 lights up the lamp tube 16, projecting light onto the surface of the medicine box from all sides. This surround lighting method can effectively avoid shadows or reflections caused by a single-direction light source. The vision sensor 5 captures images under uniform lighting conditions, significantly improving image contrast and edge recognition capabilities. The light is first emitted by the lamp tube 16 and passes through the diffuser plate 17, which can transform the originally concentrated or striped light into a soft and uniform surface light source, further improving the imaging quality.
