Description

Technical Field

[0001] The present invention relates to the technical field of packaging, and in particular to a packaging box final inspection machine. Background Art

[0002] During the production process of packaging boxes, it is necessary to check whether there are defective boxes and whether they meet the production requirements. At present, the packaging box production line usually uses manually operated machines to check one by one, which is not compatible with the packaging box production line with high automation. Manual operation inspection is inefficient, time-consuming and labor-intensive, which reduces the production efficiency of the enterprise and increases production costs. Summary of the invention

[0003] The object of the present invention is to provide a final inspection machine for packaging boxes, which can quickly and automatically detect and judge the quality of packaging boxes and screen out defective packaging boxes.

[0004] The technical solution of the present invention to solve the above technical problems is as follows:

[0005] A packaging box final inspection machine comprises: a frame and an automatic transmission component, a detection component, a waste discharge component and a control component arranged on the frame;

[0006] The detection component includes an anti-foolproof sensor, an in-place sensor, a material-blocking cylinder and a feature detection element. The material-blocking cylinder is arranged above the automatic conveying component, the anti-foolproof sensor is arranged on one side of the automatic conveying component, the in-place sensor is arranged below the automatic conveying component and the distance between the in-place sensor and the anti-foolproof sensor along the conveying direction of the packaging box is equal to the normal spacing between two packaging boxes, the anti-foolproof sensor and the in-place sensor are connected to the material-blocking cylinder through an electromagnetic valve, a material-blocking plate is arranged on the power output shaft of the material-blocking cylinder, the feature detection element is arranged above the conveyor belt, and the feature detection element is connected to the control component;

[0007] The waste discharge component is arranged downstream of the detection component. The waste discharge component includes a kicking cylinder and a material trough. The material trough is arranged on both sides of the automatic transmission component. The kicking cylinder is arranged above the automatic transmission component. A kicking rod is provided on the power output shaft of the kicking cylinder. The kicking cylinder is connected to the control component through an electromagnetic valve.

[0008] In the present invention, an automatic conveying component is used to convey the packaging boxes throughout the entire process, and a detection component and a waste discharge component are arranged along the automatic conveying component to detect the quality of the packaging boxes and remove abnormal packaging boxes; an in-place sensor is provided in the detection component, and when the packaging box is transported to the in-place sensor, the in-place sensor triggers the feature detection element to detect relevant parameters of the packaging box, and the feature detection element is connected to the control component so that the detected parameters of the packaging box can be transmitted to the control component, and the control component compares the pre-set parameter information and outputs instructions to continue to convey the normal packaging boxes forward and process the abnormal packaging boxes through the waste discharge component; the waste discharge component includes a waste discharge cylinder and a material trough, and the waste discharge cylinder drives the kick rod to remove the abnormal packaging boxes from the assembly line into the material trough; in addition, in order to prevent the feature detection element from making a misjudgment due to the close distance between the two packaging boxes, an anti-fool sensor and a material blocking cylinder are also provided upstream of the in-place sensor. The distance between the anti-foolproof sensor and the in-place sensor is equal to the distance between the two packaging boxes under normal circumstances. When the two packaging boxes are at a normal distance, when the front packaging box triggers the in-place sensor, the rear packaging box just does not trigger the anti-foolproof sensor. The control component controls the feature detection element to detect the front packaging box. When the two packaging boxes are close to each other, when the front packaging box triggers the in-place sensor, the rear packaging box triggers the anti-foolproof sensor. At this time, the control component controls the blocking cylinder to block the rear packaging box from moving forward, and the front packaging box is detected. When the detection is completed and the front packaging box has exceeded the in-place sensor, the in-place sensor is turned off, and the anti-foolproof sensor is still in the triggered state. The control component controls the blocking cylinder to retract, and the rear packaging box continues to move forward for detection. That is, the distance between the two packaging boxes can be adjusted by the different triggering states of the in-place sensor and the anti-foolproof sensor.

[0009] Furthermore, in a preferred embodiment of the present invention, the control component includes a feature matching device and a controller connected to the feature matching device, the feature detection element is connected to the feature matching device, and the controller is connected to the kicking cylinder.

[0010] In this solution, the feature matching device is a computer. The appearance parameters and barcode parameters of the standard packaging box are pre-input into the computer, and the parameters are compared with the information detected by the feature detection element. When the information matches, the controller does not work and the packaging box continues to be transported forward. When the information matches fail, that is, the packaging box is abnormal, the controller controls the exhaust cylinder to kick the abnormal packaging box into the material trough.

[0011] Furthermore, in a preferred embodiment of the present invention, the feature detection element includes a barcode scanner and a plurality of cameras.

[0012] In this solution, the feature detection elements are a camera and a barcode scanner. The barcode scanner collects barcode information of the packaging box to determine the type of the packaging box. The pre-set parameters of different packaging boxes are called up from the computer through the barcode information, and then matched with the parameters collected by the camera. The camera is used to photograph the packaging box and collect information parameters such as the packaging box's external dimensions, pattern position, and color. The number of cameras is not specifically limited and can be determined according to actual detection needs.

[0013] Furthermore, in a preferred embodiment of the present invention, multiple light sources are provided at multiple cameras.

[0014] Multiple light sources are set around the camera to facilitate clearer camera shooting and more accurate parameter collection.

[0015] Furthermore, in a preferred embodiment of the present invention, the power output shaft of the material blocking cylinder extends in a vertical direction.

[0016] Since the material blocking cylinder is arranged above the conveying assembly, the power output shaft of the material blocking cylinder is extended or retracted in the vertical direction, thereby driving the material blocking plate to block or release the packaging box.

[0017] Furthermore, in a preferred embodiment of the present invention, the power output shaft of the kicking cylinder extends in a horizontal direction, one end of the kicking rod is arranged on the power output shaft of the kicking cylinder, and the other end of the kicking rod extends to the automatic conveying component.

[0018] The material trough is arranged on both sides of the conveying component, and the kicking cylinder drives the kicking rod to remove the abnormal packaging box into the material trough by moving left and right.

[0019] Furthermore, in a preferred embodiment of the present invention, the automatic conveying component includes a panel and two conveyor belts disposed on the panel and spaced apart from each other, and position adjustment rods are respectively provided at the feed inlets of the two conveyor belts.

[0020] The two sides of the packaging box are placed on two conveyor belts and are driven forward by the conveyor belts. Adjustment rods are set at the entrance of the conveyor belt to facilitate the adjustment of the direction of the packaging box on the conveyor belt so that the packaging box is straightened to facilitate the subsequent detection of accurate information.

[0021] Furthermore, in a preferred embodiment of the present invention, a through hole is provided on the panel, the in-position sensor is arranged on a rack below the through hole, and a light source is also provided on the rack below the through hole.

[0022] The present invention has the following beneficial effects:

[0023] The present invention provides a final inspection machine for packaging boxes, which conveys the packaging boxes forward through a conveying component, and a detection component and a waste discharge component are sequentially arranged along the conveying component. The detection component can automatically detect the parameters of the packaging boxes, and the detection component is also provided with an anti-fool sensor and a material blocking cylinder for adjusting the spacing between adjacent packaging boxes to avoid misdetection of packaging box parameters, thereby further ensuring the detection accuracy. The waste discharge component can make judgments based on the information detected by the detection component and remove abnormal packaging boxes from the assembly line. The entire detection process is fully automatic and does not require manual operation. Compared with manual detection, the detection accuracy and detection efficiency are greatly improved, and the overall structure of the device is simple, which is convenient for promotion and use in the packaging industry.

At this time, the controller receives the signal and triggers the blocking cylinder 33 to work. The blocking cylinder 33 drives the blocking plate 331 to move downward, blocking the next packaging box so that it cannot continue to move forward. At the same time, the controller triggers the camera 341 and the barcode scanner 342 to work and collect information about the previous packaging box. Figure 5 In the schematic diagram (c), when the information of the previous package box is collected and it continues to be transported forward, the in-position sensor 32 is turned off. At this time, the anti-fool sensor 31 is still triggered. The controller receives the signal and triggers the material blocking cylinder 33 to retract. The next package box can continue to be transported forward for inspection.
