Description

Technical Field

[0001] This utility model relates to an online camera inspection device for paper containers. Background Technology

[0002] The use of cameras for both photographic and inspection of paper containers is a mature technology, capable of detecting defects such as shape, stains, and flaws. Cameras can be integrated into paper container production equipment (such as paper cup machines) for online inspection, meaning inspection can be performed during the paper container production process. Currently, paper container production equipment like paper cup machines is producing paper containers at increasingly faster speeds, and high-speed inspection cameras can meet the photographic inspection needs of high-speed paper cup machines. Furthermore, the equipment structure is relatively compact, with limited workstations, and each workstation is already equipped with corresponding existing mechanisms or devices.

[0003] In addition, tall cups have a higher body than short cups. When using a single camera to inspect a paper cup with its rim facing upwards, it is difficult for the single camera to completely inspect the entire inner wall, inner bottom, and other internal cavities (including the rim) of the paper cup, which cannot meet the inspection requirements. Utility Model Content

[0004] In view of the technical problems existing in the background art, the present invention aims to provide an online camera inspection device for paper containers that can completely inspect the inner cavity of paper containers. It meets the requirements of workstation layout, does not occupy other workstations, and satisfies the requirement of complete inspection. To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an online camera inspection device for paper containers, including a camera inspection station, which is configured at the turntable of intermittent indexing and cup making and transfer. The device is characterized in that: a first camera, a second camera and a third camera are configured at the camera inspection station. The first camera is configured below the turntable and faces upward. The second and third cameras are configured above the turntable and face downward. Cup receiving rings are arranged along the circumferential direction on the turntable. The cup receiving rings on the turntable have a rotating stop position at the camera inspection station. The first camera is configured below the rotating stop position. The second camera and the third camera are located above the rotating stop position, with the second camera configured on the rotation input side of the rotating stop position and the third camera configured on the rotation output side of the rotating stop position.

[0005] The following optimizations or supplementary explanations can be made to the above technical solutions.

[0006] For example, the first camera is positioned directly below the rotating stop position, the second camera is positioned directly above the rotating stop position slightly behind it, and the third camera is positioned directly above the rotating stop position slightly forward it. The second and third cameras are positioned adjacent to each other, and the rotation axis of the turntable is vertically oriented.

[0007] The second camera is positioned above the rotation path of the cup ring before it reaches the rotation stop position as the turntable rotates.

[0008] The third camera is positioned above the rotation path of the cup ring as it rotates out of the rotating stop position.

[0009] The cup-receiving ring also has a forward stopping position and a backward stopping position located in the rotation direction of the turntable. The forward stopping position is upstream of the rotation stopping position, and the backward stopping position is downstream of the rotation stopping position. The rotation stopping position of the cup-receiving ring is located between the forward stopping position and the backward stopping position. The rotation stopping position is adjacent to both the forward stopping position and the backward stopping position. The second camera and the third camera are located between the forward stopping position and the backward stopping position.

[0010] The second camera is positioned above the rotating path of the cup-receiving ring between the front stop position and the rotating stop position, and the third camera is positioned above the rotating path of the cup-receiving ring between the rotating stop position and the rear stop position.

[0011] In addition, the first camera is a bottom detection camera; the second and third cameras are respectively a top detection camera for the inner cavity and a bottom detection camera for the inner cavity.

[0012] The turntable can also be set as a transfer turntable for making cup mouths in paper cup and bowl forming equipment.

[0013] The beneficial effects of this utility model are that the online camera inspection device for paper containers, with the first camera, second camera and third camera working together with the turntable to inspect the paper containers in production, does not occupy other stopping positions (and corresponding workstations) during the turntable rotation intervals, and has a relatively compact structure; it can completely inspect the inner cavity of the paper container and can meet the inspection requirements of long cups (tall cups).

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the implementation of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Referring to the accompanying drawings, the paper container online camera inspection device in this embodiment includes a camera inspection station 123, which is located at the turntable 4 for intermittent indexing and cup making. The turntable 4 cooperates in transferring and making paper containers 6 during the intermittent indexing rotation.

[0019] Camera inspection station 123 is equipped with a first camera 1, a second camera 2 and a third camera 3 to inspect the paper container 6 on the turntable 4.

[0020] The first camera 1 is positioned below the turntable 4, facing upwards, and can take pictures of the bottom of the paper container 6 on the turntable 4 for detection.

[0021] The second camera 2 and the third camera 3 are positioned above the turntable 4, with the second camera 2 and the third camera 3 facing downwards. The second camera 2 and the third camera 3 can take pictures of the inner cavity of the paper container 6 on the turntable 4 for detection.

[0022] The turntable 4 is equipped with cup-receiving rings 40 arranged along its circumference (i.e., its rotation direction). These rings support the paper containers 6, allowing them to be transferred and processed on the turntable 4. For example, the turntable 4 serves as a transfer turntable for cup rim production in a paper cup and bowl forming machine. Paper containers 6 (such as paper cups or bowls) are input and output on the turntable 4. Between input and output, the rims of the paper containers 6 undergo processes such as oiling, preheating, pre-winding, final roll one, final roll two, and inspection. Some processes also require pressing down after input to align the relative height of the paper containers. Typically, each process corresponds to one workstation.

[0023] The cup-receiving ring 40 on the turntable 4 has a rotating stopping position 41 at the camera detection station 123. The paper container 6 on the cup-receiving ring 40 will stop at this rotating stopping position 41 during the rotation and transfer of the turntable 4. The first camera 1 is positioned below the rotating stop position 41 so that the first camera 1 can be positioned and take pictures of the bottom of the paper container 6 at the stop position. The second camera 2 is positioned on the rotary input side 42 of the rotary stop position 41, and the third camera 3 is positioned on the rotary output side 43 of the rotary stop position 41, so that the second camera 2 and the third camera 3 are arranged and coordinated to detect the integrity of the inner cavity of the paper container 6. The second camera 2 and the third camera 3 are located on the upper side of the rotary stop position 41.

[0024] Its working principle is that the camera detection station 123 is directly configured at the turntable 4 of the intermittent indexing cup making and transfer. It can cooperate in the detection of paper container 6 during the cup making process, which is relatively efficient. Moreover, the structure is reasonably arranged and does not occupy the other stations or the stopping positions during the rotation of the turntable 4. The structure is relatively compact and can directly optimize and upgrade the original equipment without changing the original operating structure and mode of the turntable 4, making it more practical. During operation, the paper container 6, positioned on the receiving ring 40, rotates intermittently with the turntable 4. The turntable 4 carries the paper container and rotates it to the rotating stop position 41, where it stops. Then, the turntable 4 continues to rotate, carrying the paper container away from the rotating stop position 41. During this movement in and out of the rotating stop position 41, the second camera 2 and the third camera 3 work together to complete the full inspection of the inner cavity of the paper container. Specifically, one of the second camera 2 and the third camera 3 can photograph and inspect the lower part (lower half) of the inner cavity of the paper container 6, while the other can photograph and inspect the upper part (upper half) of the inner cavity, completing the inspection during the rotational movement in and out. Additionally, the first camera 1 can inspect the bottom of the paper container 6 while it is stationary. In other words, the first camera 1 is the bottom inspection camera; one of the second camera 2 and the third camera 3 is the upper inner cavity inspection camera, and the other is the lower inner cavity inspection camera.

[0025] This online camera inspection device for paper containers uses a first camera 1, a second camera 2, and a third camera 3 in conjunction with the rotation and stopping of a turntable 4 to inspect paper containers in the process of production. It does not occupy other stopping positions (and corresponding workstations) during the rotation intervals of the turntable 4, and has a relatively compact structure. It can completely inspect the inner cavity of the paper container and can meet the inspection requirements of long cups (tall cups).

[0026] The following optimizations or further explanations can be made based on the above embodiments.

[0027] For example, the first camera 1 is positioned directly below the rotating stop position 41 to better align with the bottom of the paper container; the second camera 2 is positioned directly above the rotating stop position 41 at a slightly rearward position so that when the camera moves into the rotating state of the rotating stop position 41, the second camera 2 can detect the paper container below and take pictures during the rotating motion; the third camera 3 is positioned directly above the rotating stop position 41 at a slightly forward position so that when the camera moves away from the rotating stop position 41, the third camera 3 can detect the paper container below and take pictures during the rotating motion; the second camera 2 and the third camera 3 are positioned adjacent to each other in a relatively compact manner.

[0028] The rotation axis of turntable 4 is set vertically, that is, turntable 4 rotates intermittently around the vertical axis.

[0029] The second camera 2 is positioned above the rotation path of the cup ring 40 before it rotates to the rotation stop position 41, and the third camera 3 is positioned above the rotation path of the cup ring 40 as it rotates out of the rotation stop position 41.

[0030] The cup-receiving ring 40 also has a front stopping position 44 and a rear stopping position 45 located in the rotation direction of the turntable 4. The front stopping position 44 is upstream of the rotation stopping position 41, and the rear stopping position 45 is downstream of the rotation stopping position 41. The rotation stopping position 41 of the cup-receiving ring 40 is located between the front stopping position 44 and the rear stopping position 45, and the rotation stopping position 41 is adjacent to both the front stopping position 44 and the rear stopping position 45. The second camera 2 and the third camera 3 are located between the front stopping position 44 and the rear stopping position 45, forming a relatively compact layout. The second camera 2 and the third camera 3 are distributed close to the rotation input side 42 and the rotation output side 43 of the rotation stopping position 41 to avoid affecting other workstations and other stopping positions. The second camera 2 is correspondingly set above the rotation path of the cup-receiving ring 40 between the front stopping position 44 and the rotation stopping position 41, and the third camera 3 is correspondingly set above the rotation path of the cup-receiving ring 40 between the rotation stopping position 41 and the rear stopping position 45.
