Description

Technical Field

[0001] The present invention belongs to the technical field of detection equipment, and more specifically, relates to a detection device and method for the filling material of a packing box. Background Art

[0002] When bottled drinks are packed in a packing box, in order to shock-absorb or place different numbers of bottles, it is necessary to fill the gap between the packing box and the internal bottles with filling materials such as cardboard or foam to prevent the internal bottles from tipping or colliding. In actual production, the filling materials in some packing boxes may not be correctly filled (that is, not filled or the filling does not reach the expected effect) due to worker omission or equipment failure. Such problematic packing boxes are very likely to deform and become unstable during stacking storage and transportation, easily causing the internal bottles to break, and in severe cases, the entire stack of products may tip over, posing a safety hazard. Since the inside of the packing box cannot be seen once it is sealed, it is relatively difficult to check whether the internal filling materials are correctly filled. Therefore, to solve this problem currently, workers are usually arranged to specifically check before the packing box is sealed. Although this can basically meet the requirements, there is still a possibility of omission, and it is relatively labor-intensive, which is not conducive to reducing production costs. Summary of the Invention

The middle of the support lever is rotatably connected to the side of the blocking frame facing away from the packaging box to form a fulcrum. The trigger rod is slidably arranged on the blocking frame, and one end is connected to the support lever and the other end is used to contact the packaging box.

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0036] It should be further noted that the drawings and embodiments of the present invention mainly describe and illustrate the concept of the present invention. On the basis of this concept, the specific forms and settings of some connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be completely described. However, on the premise that those skilled in the art understand the concept of the present invention, those skilled in the art can implement the above specific forms and settings in a well-known manner.

[0037] When an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0038] The orientation terms "inside" and "outside" refer to the inside and outside of the contour of each component itself. The terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0039] The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, the meaning of "a plurality" is two or more, and the meaning of "several" is one or more, unless otherwise specifically defined.

[0040] Now, the packaging box filler detection device and method provided by the present invention will be described.

[0041] Such as Figure 1As shown in the figure, the packing box filler detection device provided by the first embodiment of the present invention includes a conveyor 10, a shaking mechanism, a gantry 30, a mounting seat 40, and a filler detection component 50. The conveyor 10 is used to convey the packing box 80; the shaking mechanism is arranged on the conveyor 10 to shake the passing packing box 80; the gantry 30 straddles the conveyor 10; the mounting seat 40 is slidably arranged on the gantry 30; the filler detection component 50 is arranged on the mounting seat 40 to detect the passing packing box 80.

[0042] At the same time, the present invention also provides a method for detecting the filler of a packing box, which applies the above-mentioned packing box filler detection device, and includes the following steps:

[0043] The packing box 80 to be detected is transported to the conveyor 10 through the previous process, shaken by the shaking mechanism, and then passes through the gantry 30 and is detected by the filler detection component 50 to check whether it is correctly filled. If it is correctly filled, it can directly pass through. If it is not correctly filled, preset operations including alarm or shutdown can be performed.

[0044] Compared with the prior art, when the packing box filler detection device and method provided in this embodiment are used, the packing box 80 to be detected is transported to the conveyor 10 through the previous process, shaken by the shaking mechanism, and then passes through the gantry 30 and is detected by the filler detection component 50 to check whether it is correctly filled. If it is correctly filled, it can directly pass through. If it is not correctly filled, preset operations such as alarm and shutdown can be performed; since the bottle placement positions of the equipment for loading bottles into the packing box 80 are fixed, the shaking mechanism can shake the packing box 80 and the bottles inside it. If the bottles in the packing box 80 are not fixed by the filling material, they will shift or fall in the packing box 80 and can be more easily detected when passing through the filler detection component 50; in this way, not only can it detect whether the internal filling material is correctly filled after the packing box is sealed, but also it can replace manual detection, improve the detection accuracy and reduce the labor cost. It can also repeatedly detect and confirm the sealed packing box 80 before warehousing and transportation to ensure the accuracy of detection and avoid missed detection.

[0045] As Figure 1 and Figure 5 shown, a specific embodiment provided by the present invention on the basis of the first embodiment is as follows:

[0046] The gantry 30 is provided with a plurality of mounting seats 40 and a plurality of filler detection components 50. The mounting seat 40 is slidably connected to the gantry 30 in the horizontal direction, vertical direction or oblique direction, and the mounting seat 40 is provided with a fastening component to fix the mounting seat 40 on the gantry 30. This can facilitate adjusting the quantity, orientation and position of the filler detection component 50 according to the arrangement of the filling materials in different packing boxes, so as to enhance the applicability.

[0047] Further, the packing box filler detection device further includes a controller 51 and an alarm component 52. The controller 51 is electrically connected to the filler detection component 50 and the alarm component 52 respectively, so as to control the alarm component 52 to emit an alarm signal according to the signal transmitted by the filler detection component 50.

[0048] After the filler detection component 50 detects that the filling material in the packing box 80 is not correctly filled, the signal is transmitted to the controller 51, and the controller 51 controls the alarm component 52 to emit an alarm signal to remind the user to pay attention.

[0049] Further, the controller 51 is electrically connected to the electric control part of the conveyor 10, so that after the filler detection component 50 detects that the filling material in the packing box 80 is not correctly filled, the conveyor 10 is controlled to stop running, thereby avoiding the situation that the user fails to receive the alarm signal in time or fails to process it in time, making it difficult to find the problematic packing box 80.

[0050] Specifically, the conveyor 10 includes a roller conveyor or a belt conveyor, etc., which are conveying devices that can drive the packing box 80 to pass through the shaking mechanism and the filler detection component 50; the filler detection component 50 includes an ultrasonic probe, an X-ray probe, an electromagnetic detection probe, etc., which are one or more of the components that can detect the filler in the packing box 80. The ultrasonic probe can judge whether the filling material is correctly filled by the difference in density and shape, and is suitable for drinks with thin packing boxes. The X-ray probe can judge whether the filling material is correctly filled by the difference in shape, and is suitable for drinks without metal packaging. The electromagnetic detection probe can judge whether the filling material is correctly filled by the difference in metal materials, and is especially suitable for drinks in aluminum cans or iron pipes; the alarm component 52 includes an indicator light, a speaker, a vibrator, a display, a wireless communication module, etc., which are one or more of the components that can provide an alarm signal to the user; the controller 51 includes a PLC controller or an industrial computer, etc., which are one or more of the components that can receive, process and judge the detection signal from the filler detection component 50 and control the alarm component 52 according to the detection signal.

[0051] For more accurate detection, an identification strip can also be attached to filling materials such as foam. The filler detection component 50 can be an ultrasonic probe, an X-ray probe, an electromagnetic detection probe or a Bluetooth module, etc., which are detection devices that can cooperate with the identification strip for identification. The identification strip can be a sticker with ultrasonic characteristics, X-ray characteristics, electromagnetic characteristics or Bluetooth characteristics, and is pasted on the side of the filling material facing the electromagnetic detection probe. In a specific embodiment, when the filler detection component 50 is an electromagnetic detection probe, the identification strip can be a tape with metal wires spaced apart, and is pasted on the side of the filling material facing the electromagnetic detection probe.

[0052] Furthermore, the packing box filler detection device further includes a weighing component 70 which is arranged on the conveyor 10 to weigh the passing packing box 80, and the weighing component 70 is electrically connected to the controller 51. The controller 51 receives the weight signal detected by the weighing component 70, and after determining that the weight of the packing box 80 is abnormal, controls the alarm component 52 to send out an alarm signal to alert the user.

[0053] Since the weights of the products in the same batch are consistent and the weight difference is within a relatively small error range, the weighing component 70 can directly identify when the weight of the packing box 80 is abnormal; when the weight of the filling material in the packing box 80 is relatively large or the number of bottles in the packing box 80 is incorrect, the weighing component 70 can also identify whether there is filling material in the packing box 80 or the number of bottles is incorrect. Therefore, it can be used as a backup detection means or a way to test the detection effect of the filler detection component 50; when the weight of the filling material in the packing box 80 is relatively small, it is easy to generate false alarms when using the weighing component 70 to identify whether there is filling material in the packing box 80, so it can be set as needed.

[0054] As Figures 1 to 5 shown, a specific implementation manner provided by the present invention on the basis of the first embodiment is as follows:

[0055] As Figure 1 and Figure 2 shown, the shaking mechanism includes a support frame 21, a rotating shaft 22, a track disk 23, a limiting column 24 and a plurality of packing box fixing units. The support frame 21 is arranged on the conveyor 10, the rotating shaft 22 is rotatably arranged on the support frame 21 and has the freedom of axial movement. The plurality of packing box fixing units are arranged around the rotating shaft 22. The track disk 23 is fixedly arranged on the rotating shaft 22, a track groove 231 is arranged on the edge of the track disk 23, one end of the limiting column 24 is fixedly connected to the support frame 21, and the other end is located in the track groove 231 to cooperate with the track groove 231 to drive the rotating shaft 22 and the plurality of packing box fixing units to move axially; each packing box fixing unit includes a blocking frame 25 and two side limiting components. The blocking frame 25 is fixedly connected to the rotating shaft 22 and is used to contact the front end face of the packing box 80. Here, the front end of the packing box 80 refers to the face facing forward when the packing box 80 moves forward. The two side limiting components are respectively located on the left and right sides of the blocking frame 25 and are used to abut against the side faces of the packing box 80 to drive the packing box 80 to shake left and right when the packing box fixing unit moves left and right.

[0056] During use, the packing box 80 is driven by the power of the previous process or the power of the conveyor 10 and moves forward on the conveyor 10. After the packing box 80 contacts one of the packing box fixing units, it drives this packing box fixing unit to continue moving forward and is limited and fixed by the stop frame 25 and the two side limiting components. At the same time, it also causes the packing box fixing unit to rotate around the axis of the rotating shaft 22, thereby driving the track disk 23 to rotate. The cooperation between the track groove 231 and the limiting column 24 causes the packing box fixing unit to move left and right after rotating a certain angle. At this time, the packing box 80 is exactly fixed in the packing box fixing unit, so it will be shaken left and right by the packing box fixing unit. Then the packing box 80 continues to move forward and separates from the packing box fixing unit, and is detected after passing through the gantry 30. And the subsequent packing box fixing unit just runs to the starting position of this packing box fixing unit, and can cooperate with the next packing box 80 to complete the above process; the power source of this process all comes from the inertia of the packing box 80 and the power of the conveyor 10. Therefore, the shaking mechanism does not need to be provided with another power mechanism. And if necessary, a power device can also be provided on the rotating shaft 22 to provide power, or a damping structure can be provided to increase the resistance, so that the packing box fixing unit can better contact the packing box 80. Moreover, such a design also reduces the speed of the packing box 80, which is beneficial to increasing the accuracy of the subsequent detection process.

[0057] In the actual design process, the outer diameter of the track disk 23 can be designed to be as large as possible, so that the track groove 231 therein will be longer, and it is easier to increase the shaking strength and frequency when the limiting column 24 cooperates with the track groove 231.

[0058] In some scenarios, the form of cooperation between the track disk 23 and the limiting column 24 can also not be used, but other structures that can periodically drive the rotating shaft 22 to move axially along with the rotating shaft 22 can be adopted, such as installing cylinders or push rods at both ends of the rotating shaft 22. After the rotation angle of the rotating shaft 22 reaches the rated angle, the cylinders or push rods at both ends of the rotating shaft 22 alternately push the rotating shaft 22 to move axially. The rotation angle of the rotating shaft 22 can directly control the movement of the cylinders or push rods through a mechanical angle switch, or can detect through an angle sensor and then control the movement of the cylinders or push rods through a controller, but additional power needs to be provided.

[0059] Further, such as Figure 3As shown, the side limiting assembly includes a support lever 26, a trigger lever 27, a return spring 28, and a limit claw 29. The middle of the support lever 26 is rotatably connected to the side of the baffle frame 25 facing away from the packaging box 80 to form a fulcrum. The trigger lever 27 is slidably arranged on the baffle frame 25, with one end connected to the support lever 26 and the other end for contacting the packaging box 80. The middle of the limit claw 29 is rotatably connected to the end of the baffle frame 25, with one end for contacting the side of the packaging box 80 and the other end for contacting the end of the support lever 26. The two ends of the return spring 28 are respectively connected to the support lever 26 and the baffle frame 25, so that the trigger lever 27 protrudes from the side of the baffle frame 25 facing the packaging box 80 in the natural state.

[0060] The contact and fixation process between the packaging box 80 and the packaging box fixing unit is as follows: In the natural state of the packaging box fixing unit, the return spring 28 provides elastic force to make the end of the trigger lever 27 protrude from the side of the baffle frame 25 facing the packaging box 80, and the support lever 26 does not support the limit claw 29, so that the limit claw 29 can open outward at a certain angle, enabling the packaging box to smoothly enter the C-shaped structure formed by the limit claw 29 and the baffle frame 25; after the packaging box 80 enters the packaging box fixing unit, the packaging box 80 impacts the trigger lever 27, causing the trigger lever 27 to slide back, driving the support lever 26 to rotate around the fulcrum by a certain angle, and then making the end of the support lever 26 support on the limit claw 29. After the limit claw 29 is supported by the support lever 26, it rotates, thereby clamping both sides of the packaging box 80. At this time, the packaging box fixing unit just moves left and right under the cooperation of the track groove 231 and the limit post 24, and then drives the packaging box 80 to shake left and right; after the shaking, the packaging box 80 drives the packaging box fixing unit to continue moving forward, so that the front end face of the packaging box 80 is separated from the trigger lever 27, and the trigger lever 27 no longer provides support force for the support lever 26, causing the support lever 26 to reset under the drive of the return spring 28. At the same time, the trigger lever 27 also resets and slides out, and the limit claw 29 no longer receives support and releases the packaging box 80 until the packaging box 80 is completely separated from the packaging box fixing unit. Such a structure enables the limit claw 29 to have a certain degree of opening and closing, facilitating the entry and fixation of the packaging box 80. Moreover, the power completely comes from the inertia of the packaging box 80 and the power of the conveyor 10, with a simple structure and convenient use.

[0061] Furthermore, as Figure 3 and Figure 4As shown in the figure, the ends of the support levers 26 of the two side limiting components are provided with meshing teeth 262 that cooperate with each other, so that the support levers 26 on the two side limiting components can be linked, and they can also abut against each other when shaking left and right, so as to more powerfully support the limiting claws 29. The two side limiting components share the same trigger rod 27, and the trigger rod 27 is respectively connected to the support levers 26 of the two side limiting components through two connecting rods 271. This can not only facilitate the transmission of motion, but also avoid the wear caused by displacement problems when the trigger rod 27 is directly connected to the support lever 26.

[0062] Specifically, the support frame 21 is a bracket and is provided with a supporting groove. The rotating shaft 22 is placed on the supporting groove to facilitate the formation of a rotational connection structure with axial movement freedom; the track disk 23 is a cylindrical structure, and the track groove 231 is provided on the cylindrical surface of the track disk 23 to enhance the anti-wear performance and reduce the possibility of faults; one end of the limiting column 24 located in the track groove 231 is provided with a bearing 241 to reduce the friction between the limiting column 24 and the track groove 231; one end of the support lever 26 in contact with the limiting claw 29 is provided with a ball component 261 to reduce the friction between the support lever 26 and the limiting claw 29. The limiting claw 29 is provided with a limiting groove 291 for accommodating the end of the support lever 26 to prevent the support lever 26 from disengaging from the limiting claw 29 and causing a fault.

[0063] Furthermore, as Figure 4 and Figure 5 shown, the packing box filler detection device further includes a sound detection component 60. The sound detection component 60 is provided on the trigger rod 27 and is connected to the controller 51. Since when the packing box containing glass bottles, iron cans or aluminum cans is not correctly filled with filling materials, after being shaken by the shaking mechanism, the internal bottles will collide and make a sound. By setting the sound detection component 60, a signal can be transmitted to the controller 51 after the detected sound exceeds a certain threshold. The controller 51 controls the alarm component 52 to emit an alarm signal and controls the shaking mechanism to stop moving to avoid damage to the internal bottles due to collision; the sound detection component 60 includes a sound insulation cover 61, a sound sensor 62, a data processor 63, a data transmission module 64 and a power supply module 65. One end of the sound insulation cover 61 is connected to the trigger rod 27, and the other end is used to contact the packing box 80. The sound sensor 62 is provided in the sound insulation cover 61 to detect the sound in the packing box 80. The data processor 63 is electrically connected to the sound sensor 62, the data transmission module 64 and the power supply module 65 respectively. The data transmission module 64 is connected to the controller 51.

[0064] During detection, after the packaging box 80 moves over and contacts the sound insulation cover 61, a cavity closed to the outside world is formed inside the sound insulation cover 61 to reduce the influence brought by external noise. The sound insulation cover 61 can be an elastic horn-shaped structure, which can not only gather sound but also play a certain buffering role. After that, the sound sensor 62 detects the sound emitted by the packaging box 80 during shaking to form an electrical signal and transmits it to the data processor 63. After the data processor 63 processes the electrical signal, it is transmitted to the controller 51 through the data transmission module 64. The controller 51 controls according to the transmitted signal.
