Description

Technical Field

[0001] This utility model relates to the field of packaging boxes, and in particular to a device for detecting missing labels on diluent packaging boxes. Background Technology

[0002] In industrial production and logistics, there are strict requirements for product packaging labeling. Labels on packaging contain crucial product information, such as product name, specifications, instructions for use, production date, shelf life, and batch number. This information is vital for product traceability, use, storage, and sales. Taking the production of diluents as an example, the labels on their packaging provide users with essential information about the product, ensuring correct use and storage. Simultaneously, they also assist manufacturers in quality control and market supervision.

[0003] However, in the actual labeling process, due to various reasons such as labeling machine malfunction, label supply problems, machine positioning errors, unstable label pasting, or human error, some packaging boxes may have missing labels. Therefore, a secondary inspection is required to remove packaging boxes with missing labels.

[0004] Chinese Patent Publication No. CN213727952U discloses a device for detecting packaging boxes with embedded RFID tags. This device mainly consists of a conveyor table, a detection mechanism, and a pusher plate. Its working principle is that the detection mechanism monitors the packaging boxes running on the conveyor table in real time. Once a missing tag is detected, the pusher plate is immediately activated, moving perpendicular to the conveyor table's transport direction, thereby removing the missing tag packaging box from the normal transport path. Compared to traditional manual detection and rejection methods, this design improves detection and rejection efficiency to a certain extent, effectively reduces labor costs and the missed detection rate, and solves the problem of low efficiency in manual rejection.

[0005] However, the device has certain defects in actual operation: specifically, because its push plate structure uses components such as elastic ropes, it is difficult to accurately control the magnitude of the force applied to the packaging box when performing the rejection action. Therefore, there is a possibility that the packaging box may tip over due to excessive instantaneous contact force between the push plate and the packaging box, resulting in damage to the diluent inside the packaging box.

[0006] Therefore, a device for detecting missing labels on diluent packaging boxes is needed to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a device for detecting missing labels on diluent packaging boxes, which can stably and efficiently remove missing labels from packaging boxes and meet the application requirements for actual label testing of packaging boxes.

[0008] To solve the above-mentioned technical problems, this utility model provides a device for detecting missing labels on diluent packaging boxes, including a first conveyor table, a detection device, a second conveyor table, a guiding mechanism, and a controller;

[0009] The detection device is set on the first conveyor table and is used to detect whether the packaging box has missing labels;

[0010] The second conveyor is disposed on one side of the first conveyor and is connected to or closed to the first conveyor via the guide mechanism;

[0011] The guiding mechanism is mounted on the first conveyor platform and has both a horizontal and an inclined state.

[0012] When the guiding mechanism is in a horizontal state, the first conveyor table and the second conveyor table are closed to guide the packaging box to move continuously along the conveying direction of the first conveyor table;

[0013] When the guiding mechanism is in an inclined state, the guiding mechanism forms a guiding channel to connect the first conveyor table and the second conveyor table, and the length direction of the guiding channel forms an angle with the conveying direction of the first conveyor table;

[0014] The controller is connected to the drive end of the detection device and the guide mechanism to control the guide mechanism to switch between a horizontal state and an inclined state according to the detection result of the detection device.

[0015] Furthermore, the guiding mechanism includes two parallel and staggered deflection plates;

[0016] The first conveyor table has openings on both sides for mounting the deflection plate, and one of the openings is connected to the second conveyor table;

[0017] The deflection plate is rotatably mounted at the opening;

[0018] When the guide mechanism is in a horizontal state, the deflection plate is located within the opening;

[0019] When the guiding mechanism is in an inclined state, one of the deflecting plates is located on the conveying surface of the first conveyor table to intercept and guide the packaging box, and the other deflecting plate is deflected onto the second conveyor table;

[0020] The guide channel is formed between the two deflection plates.

[0021] Furthermore, both deflection plates are rotatably mounted in the opening via rotating shafts, and the two rotating shafts are connected by a synchronous belt drive, with one of the rotating shafts connected to a drive motor;

[0022] The drive motor is connected to the controller via a signal connection.

[0023] Furthermore, a gap is reserved between the lower surface of the deflection plate and the conveying surface of both the first and second conveying platforms.

[0024] Furthermore, guide rollers are provided on the side of the two deflection plates that are close to each other.

[0025] Furthermore, multiple guide rollers are provided, and all of them are made of rubber.

[0026] Furthermore, the included angle is an acute angle.

[0027] Furthermore, the first conveyor platform is a belt conveyor, and the second conveyor platform is a roller conveyor.

[0028] Furthermore, the controller is mounted on the detection device.

[0029] Compared with the prior art, the present invention has at least the following beneficial effects:

[0030] By setting up a first conveyor table, a second conveyor table, and a guiding mechanism, with the guiding mechanism having both horizontal and inclined states, and when the guiding mechanism is in the horizontal state, the first and second conveyor tables are closed, allowing the packaging boxes to move only along the conveying direction of the first conveyor table. When the guiding mechanism is in the inclined state, a guiding channel connecting the first and second conveyor tables is formed, with the length of the guiding channel forming an angle with the conveying direction of the first conveyor table. Therefore, based on the detection results of the testing equipment, qualified packaging boxes and packaging boxes with missing labels can be continuously conveyed to the first conveyor table or guided to the second conveyor table, respectively, to complete the rejection of packaging boxes with missing labels. During this process, the packaging boxes are only subjected to the conveying power of the first and second conveyor tables, without any sudden contact from other external forces. This effectively ensures that the packaging boxes with missing labels remain in a stable state during rejection, thus effectively preventing the packaging boxes from tipping over due to excessive instantaneous force, which could lead to damage to the diluent inside the packaging boxes. This achieves a stable and efficient function in rejecting packaging boxes with missing labels, meeting the application requirements of actual packaging box label testing.

[0035] The following is a more detailed description of the labeling and leak detection device for diluent packaging boxes of this utility model, with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the utility model.

[0036] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0037] like Figures 1 to 3 As shown in the figure, this utility model embodiment proposes a labeling leak detection device for diluent packaging boxes, including a first conveyor 1, a detection device 2, a second conveyor 3, a guide mechanism 4, and a controller 5.

[0038] The detection device 2 is installed on the first conveyor table 1 and is used to detect whether the packaging box is missing a label. The detection device 2 is existing technology, such as a common machine vision-based detection mechanism, so it will not be described in detail here.

[0039] The second conveyor 3 is disposed on one side of the first conveyor 1 and is connected to or closed to the first conveyor 1 through the guide mechanism 4. The second conveyor 3 is used to receive and convey boxes with missing labels, so as to separate boxes with missing labels from qualified boxes and realize the function of rejecting boxes with missing labels.

[0040] In this embodiment, the guide mechanism 4 is disposed on the first conveyor table 1 and has a horizontal state and an inclined state.

[0041] When the guiding mechanism 4 is in a horizontal state, the first conveyor platform 1 and the second conveyor platform 3 are closed to guide the packaging box to move continuously along the conveying direction of the first conveyor platform 1. When the guiding mechanism 4 is in an inclined state, it forms a guiding channel 6 to connect the first conveyor platform 1 and the second conveyor platform 3.

[0042] In a specific example, the guide mechanism 4 is used to perform the sorting operation between qualified packaging boxes and packaging boxes with missing labels, thereby realizing the rejection of packaging boxes with missing labels. No external force is required during the sorting, thus achieving the function of stable and efficient rejection of packaging boxes with missing labels.

[0043] If the label is found to be normal after the packaging box is inspected by the inspection equipment 2, the guide mechanism 4 will be in a horizontal state, allowing the qualified packaging box to be input into the next process via the first conveyor table 1. If the label is found to be missing after the packaging box is inspected by the inspection equipment 2, the guide mechanism 4 will be controlled to be in an inclined state, so that under the conveying power of the guide channel 6 and the first conveyor table 1, it will enter the second conveyor table 3 to complete the diversion and rejection operation, achieving the purpose of stable and efficient rejection.

[0044] It should be noted that, in this embodiment, the positional relationship between the guide channel 6 and the first conveyor 1 is further defined in order to better guide the missing label packaging box into the second conveyor 3.

[0045] Specifically, the length direction of the guide channel 6 forms an angle with the conveying direction of the first conveyor table 1, that is, the guide channel 6 forms a wedge-shaped wall on the conveying surface of the first conveyor table 1. Thus, when the missing label packaging box is driven by the power of the first conveyor table 1, it can enter the second conveyor table 1 along the wedge-shaped wall to improve the guiding effect of the missing label packaging box.

[0046] Preferably, the included angle is set to an acute angle, so that when the missing label packaging box contacts the inner wall of the guide channel 6 under the conveying power of the first conveyor 1, the inner wall of the guide channel 6 can provide a component force in the direction of entering the second conveyor 3, thereby accelerating the missing label packaging box into the second conveyor 3 and further improving the guiding effect.

[0047] In addition, by setting the included angle to an acute angle, the guide channel 6 is prevented from being perpendicular to the conveying direction of the first conveyor table 1, which would cause the guide channel 6 to completely limit the missing label packaging box, resulting in the missing label packaging box getting stuck on the first conveyor table 1.

[0048] In this embodiment, the controller 5 is signal-connected to the drive end of the detection device 2 and the guide mechanism 4, so as to control the guide mechanism 4 to switch between a horizontal state and an inclined state according to the detection result of the detection device 2. That is, by setting the controller 5 to receive the information detected by the detection device 2, and complete the control of the state of the guide mechanism 4 according to the detection result, the qualified packaging boxes and the missing label packaging boxes are separated, thereby completing the rejection of the missing label packaging boxes.

[0049] This device comprises a first conveyor platform 1, a second conveyor platform 3, and a guide mechanism 4. The guide mechanism 4 has both horizontal and inclined states. When the guide mechanism 4 is in the horizontal state, the first conveyor platform 1 and the second conveyor platform 3 are closed, allowing the packaging box to move only along the conveying direction of the first conveyor platform 1. When the guide mechanism 4 is in the inclined state, a guide channel 6 is formed connecting the first conveyor platform 1 and the second conveyor platform 3, with the length of the guide channel 6 forming an angle with the conveying direction of the first conveyor platform. Therefore, it can separate qualified packaging boxes and missing labels based on the detection results of the detection equipment 3. The boxes are continuously conveyed on the first conveyor 1 or guided to the second conveyor 3 to complete the rejection of boxes with missing labels. During this process, the boxes are only subjected to the conveying power of the first conveyor 1 and the second conveyor 3, without any sudden contact from other external forces. Therefore, it can effectively ensure that the boxes with missing labels remain in a stable state during rejection. This can effectively avoid the boxes tipping over due to excessive instantaneous force, which could lead to damage to the diluent inside the boxes. This achieves the function of stable and efficient rejection of boxes with missing labels, meeting the application requirements of actual label testing.

[0050] In a further embodiment, a specific guiding mechanism 4 is proposed to better guide the packaging box.

[0051] Specifically, the guiding mechanism 4 includes two parallel and staggered deflection plates 41.

[0052] The first conveyor table 1 has openings on both sides for mounting the deflection plate 41, and one of the openings is connected to the second conveyor table 3. The deflection plate 41 is rotatably mounted at the opening. Therefore, the opening can be blocked or closed by changing the deflection state of the deflection plate 41, thereby controlling the connection or closure between the first conveyor table 1 and the second conveyor table 3.

[0053] Among them, such as Figure 2 As shown, when the guide mechanism 4 is in a horizontal state, the deflection plate 41 is located inside the opening.

[0054] like Figure 3As shown, when the guide mechanism 4 is in an inclined state, one of the deflection plates 41 is located on the conveying surface of the first conveyor table 1 to intercept and guide the packaging box, while the other deflection plate 41 is deflected onto the second conveyor table 3.

[0055] The guide channel 6 is formed between the two deflection plates 41 to guide the missing label packaging box to the second conveyor table 3, thereby completing the separation operation of qualified packaging boxes and missing label packaging boxes.

[0056] In this embodiment, both deflection plates 41 are rotatably mounted within the opening via rotating shafts 42, and the two rotating shafts 42 are connected by a synchronous belt drive, with one of the rotating shafts 42 connected to a drive motor. This ensures that the two deflection plates 41 deflect synchronously, thereby guaranteeing that the size of the guide channel 6 remains unchanged and improving the stability when guiding the packaging box.

[0057] The drive motor is connected to the controller 5 via a signal, and rotates in both directions according to the instructions of the controller 5, thereby driving the two deflection plates 41 to rotate.

[0058] It should also be noted that a gap is reserved between the lower surface of the deflection plate 41 and the conveying surface of the first conveying table 1 and the second conveying table 3, to ensure that the deflection plate 41 does not come into contact with the conveying surfaces of the first conveying table 1 and the second conveying table 3 during the deflection process, thereby improving stability.

[0059] To improve the guiding and protective effect on the packaging box and prevent damage when the packaging box comes into contact with the deflection plate 41, guide rollers 411 are provided on the side of the two deflection plates 41 that are close to each other. Multiple guide rollers 411 are provided and all are made of rubber to improve the guiding and protective effect on the packaging box.

[0060] In one example, the first conveyor 1 is a belt conveyor and the second conveyor 3 is a roller conveyor. The use of two different types of conveyor structure makes it easy for operators to determine the type of packaging boxes located on the conveyor structure (such as qualified packaging boxes or unlabeled packaging boxes) and avoids confusion.

[0061] In one embodiment, the controller 5 is disposed on the detection device 2.

[0062] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
