Description

Technical Field

[0001] This utility model relates to the field of packaging box inspection technology, and in particular to a transfer mechanism, an inspection mechanism, and an internal inspection equipment for opening boxes. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] like Figure 1 As shown, a packaging box (such as a cigarette pack) typically includes a bottom cover and a top cover. One side of the bottom cover is connected to the top cover, and the other side is called the opening side. During the production process of the packaging box, quality inspection is required. This quality inspection usually uses visual inspection technology to check the inside and outside of the packaging box.

[0004] However, existing inspection methods typically place inspection elements on both sides of the conveyor line to inspect the inner sides of the lower and upper covers. When inspecting the two ends of the packaging box, facing cameras are usually placed at a distance along the conveyor line's transport direction, resulting in a very long production line. Meanwhile, based on new process requirements, there is now a need for a mechanism that can keep the packaging box's upper cover open and maintain a specified posture for inspecting the two ends of the packaging box. Therefore, this application provides a transfer mechanism, an inspection mechanism, and an in-box inspection device to meet the aforementioned new process requirements. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings by providing a transfer mechanism, a testing mechanism, and an internal inspection device for opening the box.

[0006] To solve the above-mentioned technical problems, this utility model discloses a transfer mechanism, comprising: A top cover assembly is used to receive the top cover of a package box that is in an open position and to keep the top cover in the open position. A lower cover assembly is used to define the relative position of the lower cover of the packaging box relative to the upper cover; A displacement component, connected to the upper cover component and the lower cover component, is used to drive the upper cover component and the lower cover component to move, pushing the packaging box to a preset position; wherein the direction of movement of the packaging box is perpendicular to the direction in which the packaging box enters the upper cover component.

[0007] Furthermore, the upper cover assembly includes at least two spaced-apart limiting plates, with a space below the limiting plates for the lower cover to enter. The upper cover enters the upper cover assembly from one side in an open position, so that the upper cover is located between the two limiting plates.

[0008] Furthermore, the upper cover assembly includes a limiting plate with a space below it for the lower cover to enter. After the upper cover is moved into place, the limiting plate is located between the upper cover and the lower cover, preventing the upper cover from closing onto the lower cover.

[0009] Furthermore, the lower cover assembly includes a push plate with a stepped structure for engaging with the edge of the lower cover opening surface.

[0010] Furthermore, the lower cover assembly includes at least two pressure blocks, one of which has its bottom positioned above the lower cover, and the other pressure block is used to contact the opening surface of the lower cover to push the lower cover to move.

[0011] Furthermore, the displacement component is a conveyor belt structure, and multiple upper cover components and lower cover components are provided and distributed on the conveyor belt structure.

[0012] Furthermore, it also includes a support platform located below the displacement component, used to support the packaging box when the displacement component pushes the packaging box to move, preventing the packaging box from falling.

[0013] Furthermore, it also includes brushes disposed on both sides of the displacement component. When the moving packaging box passes by the brushes, the bristles of the brushes contact the top cover, causing the top cover to abut against a limiting plate on one side.

[0014] A testing organization, comprising: The aforementioned transfer mechanism; The detection components, located on both sides of the displacement component, are used to detect both ends of the moving packaging box.

[0015] An internal inspection device for opening boxes, comprising: The aforementioned testing facility is used to move the packaging box from the first workstation to the second workstation; The first conveying mechanism is used to convey the packaging box to the first workstation in an open position; The second conveying mechanism is used to move the packaging box from the second workstation to the next target workstation. The first conveying mechanism and the second conveying mechanism are arranged in parallel.

[0016] The beneficial effects of this utility model are reflected in: 1. In this application, the upper cover and lower cover in the open state are limited by the upper cover limit assembly and the lower cover limit assembly respectively, so that the upper cover can be opened and maintained in a specified posture, so as to detect both ends of the packaging box; 2. The packaging box is limited by the transfer mechanism, and the detection components are placed on both sides of the moving trajectory of the packaging box, so as to realize the detection of both ends of the packaging box in a certain posture to meet the detection requirements of the new process.

[0017] 3. The parallel arrangement of the first and second conveying mechanisms ensures that the packaging box maintains the same orientation throughout the process and facilitates the inspection of both ends of the box, thus achieving automated inspection. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0021] Example 1: like Figure 2-4 As shown, this utility model discloses a transfer mechanism, comprising: The upper cover assembly is used to receive the upper cover 12 of the packaging box 1 in an open position and to keep the upper cover 12 in the open position. The lower cover assembly is used to limit the relative position of the lower cover 11 of the packaging box 1 relative to the upper cover 12; The displacement component 3 is connected to the upper cover component and the lower cover component and is used to drive the upper cover component and the lower cover component to move, pushing the bottom of the packaging box 1 to a preset position; wherein the direction in which the displacement component 3 pushes the packaging box 1 to move is perpendicular to the direction in which the packaging box 1 enters the upper cover component. This application limits the upper cover 12 and the lower cover 11 in the open state by limiting the upper cover assembly and the lower cover assembly respectively, so that the upper cover 12 can be opened and maintained in a specified posture, so as to inspect both ends of the packaging box 1 to meet the inspection requirements of the new process.

[0022] like Figure 2 , Figure 3 As shown, the upper cover assembly includes at least two spaced-apart limiting plates 2. The space below each limiting plate 2 provides space for the lower cover 11 to enter. The upper cover 12 enters the upper cover assembly from one side in an open position, positioning itself between the two limiting plates 2. By limiting the upper cover 12 with the two limiting plates 2, it is possible to open the upper cover 12 and maintain it in a specified position.

[0023] Preferably, the side of the limiting plate 2 corresponding to the side where the upper cover 12 enters has a chamfer to facilitate the entry of the upper cover 12.

[0024] like Figure 2 , Figure 3 As shown, the lower cover assembly includes a push plate 4, which is connected to the displacement assembly 3 and is used to push the bottom of the packaging box 1 to move the packaging box 1. The push plate 4 has a stepped structure and is used to engage with the edge of the opening surface 13 of the lower cover 11.

[0025] Specifically, the push plate 4 includes a horizontal surface and a vertical surface. The horizontal surface is located above the opening surface 13, and the vertical surface extends downward to contact the bottom of the opening surface 13. Driven by the displacement component 3, it pushes the bottom of the opening surface 13 of the lower cover 11 to move the packaging box 1, thus preventing the side of the opening surface 13 of the lower cover 11 from tilting up during the movement.

[0026] Of course, the push plate 4 can be directly connected to the displacement component 3, or it can be connected to the displacement component 3 through a vertical connecting plate, or it can be directly connected to the limit cover component.

[0027] Preferably, the side of the transverse surface corresponding to the material receiving side of the lower cover 11 has an upwardly inclined guide plate, which facilitates the lower cover 11 entering the bottom of the transverse surface.

[0028] like Figure 4 As shown, the displacement component 3 is a conveyor belt structure, and multiple limit cover components and push plates 4 are provided and distributed on the conveyor belt structure; It also includes a support platform 5, located below the movement trajectory of the displacement component 3, which serves to support the packaging box 1 between the current workstation and the target workstation when the displacement component 3 pushes the packaging box 1 to move, and prevents the packaging box 1 from falling.

[0029] It should be noted that the displacement component 3 can also be other common linear displacement mechanisms, such as electric telescopic rods, pneumatic telescopic rods, etc. However, since telescopic displacement mechanisms such as electric telescopic rods and pneumatic telescopic rods need to move back and forth, have short lifespans and limited response speeds, they cannot operate efficiently. Therefore, this application specifically selects a conveyor belt structure as the displacement component 3.

[0030] like Figure 4 As shown, it also includes brushes 31 disposed on both sides of the displacement component 3. When the packaging box 1 moves, it passes by the brushes 31, and the bristles of the brushes 31 come into contact with the top cover 12, causing the top cover 12 to move to one side and abut against the corresponding limiting plate 2.

[0031] In practice, the brush 31 contacts one end of the corresponding opening surface 13 of the upper cover 12, and does not obstruct the detection component 9 (in actual work, the detection component 9 detects the end of the lower cover 11 and the position of the upper cover 12 corresponding to the lower cover 11). The setting of the brush 31 makes the upper cover 12 firmly stick to the corresponding limiting plate 2, so that the upper cover 12 and the lower cover 11 are in the specified posture, which makes it easier for the detection component 9 to detect both ends of the packaging box 1 and reduce detection error.

[0032] This application also discloses a testing organization, including: The aforementioned transfer mechanism; The detection components 9 are arranged on both sides of the displacement component 3 to detect both ends of the moving packaging box 1. By placing the detection components 9 on both sides of the displacement component 3, the two ends of the packaging box can be effectively detected, enabling the detection of the packaging box in a specified posture and meeting the requirements of the new process.

[0033] The detection component 9 is a commonly used visual inspection component in the prior art. It acquires information from both ends of the packaging box 1 by taking pictures (using a CCD camera or a CMOS camera) and judges defects based on the acquired image information. Since the detection component 9 is common knowledge to those skilled in the art, it will not be described in detail here.

[0034] like Figure 4 , Figure 5 As shown, this application also discloses an internal inspection device for opening the box, comprising: The aforementioned transfer mechanism is used to move the packaging box 1 from the first station to the second station; The first conveying mechanism 6 is used to convey the packaging box 1 to the first workstation in an open position; The second conveying mechanism 7 is used to move the packaging box 1 from the second workstation to the next target workstation. The first conveying mechanism 6 and the second conveying mechanism 7 are arranged in parallel.

[0035] In practice, both the first conveying mechanism 6 and the second conveying mechanism 7 adopt a conveyor belt structure. The parallel arrangement of the first conveying mechanism 6 and the second conveying mechanism 7 ensures that the box maintains a consistent orientation throughout and facilitates comprehensive inspection of both ends of the box.

[0036] like Figure 4 , Figure 5 As shown, one end of the second conveying mechanism 7 is located in the second work station, and is used to carry the packaging box 1 and drive the packaging box 1 to move linearly. A guide plate 8 is provided on one side of the second work station. The guide plate 8 is located above the lower cover 11. The packaging box 1 moves out of the second work station and passes the bottom of the guide plate 8 before moving to the next target work station.

[0037] Specifically, the lower cover 11 processed in this application has a surrounding strip 14 inside. The surrounding strip 14 extends upward into the space between the lower cover 11 and the top of the lower cover 11 to form a step. In order to ensure the stability of the lower cover 11 during the conveying process, two rows of rollers are provided on both sides of the conveyor belt to press down the step on the top of the lower cover 11 during the conveying process. The guide plate 8 is set to ensure that the lower cover 11 can be pressed down by the rollers on both sides of the conveyor belt after it is displaced from the second working part.

[0038] Example 2: The only difference between this embodiment and Embodiment 1 is the structure of the upper cover assembly: like Figure 6 As shown, the upper cover assembly includes a limiting plate 2, and the lower part of the limiting plate 2 has a space for the lower cover 11 to enter. After the upper cover 12 is moved into place, the limiting plate 2 is located between the upper cover 12 and the lower cover 11, preventing the upper cover 12 from closing on the lower cover 11.

[0039] In practice, the partially opened cover 12 has a certain rebound force. Under the action of the rebound force, the cover 12 will always stick to the limiting plate 2, so that only one limiting plate 2 is needed to keep the opened cover 12 in the specified posture.

[0040] Example 3: The only difference between this embodiment and Embodiment 1 is the structure of the lower cover assembly: like Figure 7 As shown, the lower cover assembly includes at least two pressing blocks 34, one of which has its bottom positioned above the lower cover 11, and the other pressing block 34 is used to contact the opening surface 13 of the lower cover to push the lower cover 11 to move. During operation, the opening surface 13 of the lower cover 11 is pushed by the displacement assembly 3 to move the packaging box 1, preventing the side of the lower cover 11 containing the opening surface 13 from tilting up during movement.

[0041] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0042] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0043] Additionally, "multiple" refers to two or more.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
