Description

Technical Field

[0001] This application relates to the field of paper cup production technology, and in particular to a paper cup detection device and a paper cup forming system. Background Technology

[0002] With the popularization of environmental protection concepts and the upgrading of consumption, paper tableware, due to its recyclable and biodegradable characteristics, has been widely used in commercial catering, air transportation, and mid-to-high-end fast food restaurants. As the market continues to expand, the demand for paper cup production efficiency and the accuracy of quality testing is also constantly increasing.

[0003] In existing automated paper cup production lines, quality inspection of the cup rim is typically achieved using vertically mounted industrial cameras. However, in the quality inspection of the cup bottom, if the same vertical camera mounting method is used, the limited vertical height from the cup bottom area of ​​the paper cup forming equipment to the equipment's control panel will prevent the cup bottom inspection camera from being effectively installed. If a vertically upward-mounted camera solution is forced, oil mist, paper dust, and other particles generated during the paper cup machine's operation will easily adhere to the lens, causing blurred images, increased false detection rates, and requiring frequent cleaning and maintenance, severely impacting inspection stability and overall equipment efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a paper cup detection device and a paper cup forming system that can reduce the space occupied by the detection camera in height while detecting the bottom of the paper cup, and can also reduce the contamination of the detection camera lens.

[0005] The paper cup detection device includes a paper cup detection station; the paper cup detection device has mutually perpendicular height and horizontal directions; the paper cup detection device includes a support assembly and a cup bottom detection mechanism; the support assembly includes a first assembly plate located at the bottom; the cup bottom detection mechanism is mounted on the first assembly plate; the cup bottom detection mechanism includes a cup bottom detection camera assembly, a beam splitter, and a first light source; along the height direction, the first light source is located below the paper cup detection station, and the beam splitter is located below the first light source; the beam splitter has a beam splitting surface, and the cup bottom detection camera assembly is mounted on the light output end of the beam splitter; wherein, the extension direction of the beam splitting surface is inclined relative to the height direction and the horizontal direction, defining the dimension of the cup bottom detection camera assembly along the height direction of the paper cup detection device as h, defining the length dimension of the cup bottom detection camera assembly as a, and the width dimension as b, where b≤h<a.

[0006] Understandably, a paper cup is placed at the paper cup detection station. The first light source provides light to illuminate the bottom of the paper cup, which reflects the light to the beam splitter below. Within the beam splitter, the beam splitting surface further reflects the light to the cup-bottom detection camera assembly located at the output end of the beam splitter, allowing the cup-bottom detection camera assembly to obtain an image of the bottom of the paper cup. Since the beam splitting surface is inclined relative to the height and horizontal directions, the axis of the cup-bottom detection camera assembly is aligned with the direction of light reflection from the beam splitting surface, also being inclined. Therefore, the cup-bottom detection camera assembly does not need to be vertically aligned with the height direction, eliminating the need for the lens to point upwards, reducing dust accumulation and cleaning frequency. Furthermore, by making the height dimension of the cup-bottom detection camera assembly smaller than its length dimension, the cup-bottom detection camera assembly occupies less space in the height direction, facilitating better installation without forcibly increasing the height between the first assembly plate and the paper cup detection station, thus minimizing the overall space occupied by the paper cup detection device.

The sliding direction of the first camera adjustment component is perpendicular to the height direction and parallel to the surface where the light output end of the beam splitter is located. The cup bottom detection mechanism further includes a second camera adjustment component, which is slidably connected to the first camera adjustment component. The second camera adjustment component is equipped with the cup bottom detection camera assembly and can drive the cup bottom detection camera assembly to move along the axial direction of the cup bottom detection camera assembly.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0027] Please see Figures 1 to 3 This application provides a paper cup detection device 100, which has a paper cup detection station where paper cups are placed for detection. The paper cup detection device 100 has a vertical height direction and a horizontal direction that are perpendicular to each other. The paper cup detection device 100 includes a support assembly 10 and a cup bottom detection mechanism 20. The support assembly 10 includes a first mounting plate 11 located at the bottom, and the cup bottom detection mechanism 20 is mounted on the first mounting plate 11.

[0028] In a specific embodiment, the cup bottom detection mechanism 20 includes a cup bottom detection camera assembly 21, a beam splitter 22, and a first light source 23. Along the height direction, the first light source 23 is positioned below the paper cup detection station to illuminate the bottom of the paper cup. The beam splitter 22 is positioned below the first light source 23 to receive reflected light from the bottom of the paper cup. The beam splitter 22 has a beam-splitting surface capable of reflecting the reflected light from the bottom of the paper cup again. The cup bottom detection camera assembly 21 is mounted at the light output end of the beam splitter 22, and the axis of the cup bottom detection camera assembly 21 is aligned with the direction of the reflected light from the beam splitter surface to receive the reflected light, thereby acquiring an image of the bottom of the paper cup and realizing the detection of the bottom of the paper cup.

[0029] In a specific embodiment, the extension direction of the beam-splitting surface is inclined relative to the height direction and the horizontal direction. With this setting, since the axis of the cup bottom detection camera assembly 21 is consistent with the direction of the light reflected by the beam-splitting surface, the cup bottom detection camera assembly 21 does not need to be installed vertically.

[0030] In a specific embodiment, the cup bottom detection camera assembly 21 includes a cup bottom detection camera 211 and a cup bottom detection lens 212 mounted on the cup bottom detection camera 211. The fact that the cup bottom detection camera assembly 21 does not require vertical mounting makes it less prone to dust accumulation on the cup bottom detection lens 212, reducing the frequency of cleaning and protecting the lens.

[0031] In an optional embodiment, based on the above settings, the dimension of the cup bottom detection camera assembly 21 along the height direction of the paper cup detection device 100 is further defined as h, the length dimension of the cup bottom detection camera assembly 21 is defined as a, and the width dimension is defined as b, where b ≤ h < a. This configuration, while the cup bottom detection camera assembly 21 is tilted relative to the height and horizontal directions, makes the dimension of the cup bottom detection camera assembly 21 along the height direction smaller than its own length dimension. This reduces the space occupied by the cup bottom detection camera assembly 21 along the height direction, facilitating its assembly without increasing the distance from the paper cup detection station to the first assembly plate 11 along the height direction, thus reducing the overall space occupied by the paper cup detection device 100.

[0032] In summary, it is through the setting of the beam splitter 22 and the limitation of the height dimension of the cup bottom detection camera 211 during installation that the cup bottom detection camera 211 can detect the bottom of the paper cup while reducing the space occupied in the height direction, and also reducing the dust accumulation on the cup bottom detection lens 212.

[0033] like Figure 1 As shown, in a specific embodiment, the angle between the extension direction of the beam-splitting surface and the horizontal direction is α, where 35°≤α≤55°. This configuration allows the light reflected from the beam-splitting surface to exit from the beam-splitting element 22 along a horizontal direction or along a direction with a smaller angle of inclination relative to the horizontal. Since the axis of the cup-bottom detection camera assembly 21 is aligned with the direction of the light reflected from the beam-splitting surface, the cup-bottom detection camera assembly 21 is positioned horizontally or nearly horizontally, resulting in a smaller space occupied along the height direction and facilitating its assembly. For example, α = 35°, 45°, or 55°. When α = 45°, the reflected light is horizontal, and the cup-bottom detection camera assembly 21 is placed horizontally, achieving the minimum height space occupied.

[0034] like Figure 1As shown, in a specific embodiment, the cup bottom detection mechanism 20 further includes a first assembly rod 24, which is mounted on the first assembly plate 11; the first light source 23 and the cup bottom detection camera assembly 21 are respectively mounted on the first assembly rod 24. The first assembly rod 24 provides a unified installation reference to reduce installation errors and facilitate the integrated assembly of the first light source 23 and the cup bottom detection camera assembly 21.

[0035] like Figure 1 As shown, in a specific embodiment, the cup bottom detection mechanism 20 further includes a first camera support 251, which is sleeved on the first assembly rod 24 and is adjustable circumferentially relative to the first assembly rod 24. The cup bottom detection camera 211 is mounted on the first camera support 251, which supports the camera. The height of the cup bottom detection camera 211 is adjusted by sliding the first camera support 251 on the first assembly rod 24. The first camera support 251 can also rotate circumferentially along the first assembly rod 24, causing the cup bottom detection camera 211 to rotate accordingly. This allows the cup bottom detection camera 211 to rotate to the position corresponding to the paper cup detection station after installation. After detection, it can also be rotated out with the first camera support 251, facilitating the operator to remove the cup bottom detection camera 211 from the cup bottom detection mechanism 20.

[0036] like Figure 1 As shown, in a specific embodiment, the first camera support 251 is provided with two first movable adjustment blocks 2511. The two first movable adjustment blocks 2511 surround and form a first mounting hole 2512 and a first gap 2513 communicating with the first mounting hole 2512. The first gap 2513 communicates with the outside, and the first mounting rod 24 can pass through the first mounting hole 2512. Each first movable adjustment block 2511 is provided with a first locking hole 25111. The axis of the first locking hole 25111 is set at an angle to the axis of the first mounting hole 2512. Screws are provided to pass through the first locking holes 25111 to be threadedly connected to the two first movable adjustment blocks 2511 respectively and to form a lock. In actual use, after the first camera support 251 rotates relative to the first mounting rod 24 at a certain angle to reach the desired position, the screws are tightened to make the two first movable adjustment blocks 2511 clamp the first mounting rod 24, thereby fixing the first camera support 251 relative to the first mounting rod 24.

[0037] like Figure 1As shown, in a specific embodiment, the cup bottom detection mechanism 20 further includes a first camera adjustment component 252. The first camera adjustment component 252 is slidably connected to the end of the first camera support 251 opposite to the first mounting rod 24. The cup bottom detection camera assembly 21 is mounted on the first camera adjustment component 252. The sliding direction of the first camera adjustment component 252 is perpendicular to the height direction and parallel to the plane where the light output end of the beam splitter 22 is located, so as to drive the cup bottom detection camera assembly 21 to move and adjust the position of the cup bottom detection camera assembly 21 relative to the light output end of the beam splitter 22. This facilitates compensation for possible errors during installation and allows for quick and simple position adjustment when the optical path changes.

[0038] like Figure 1 As shown, in a specific embodiment, the cup bottom detection mechanism 20 further includes a second camera adjustment component 253, which is slidably connected to the first camera adjustment component 252. The second camera adjustment component 253 is equipped with a cup bottom detection camera assembly 21. The second camera adjustment component 253 can drive the cup bottom detection camera assembly 21 to move along the axial direction of the cup bottom detection camera assembly 21, adjusting the position of the cup bottom detection camera assembly 21 on the horizontal plane. When needed, the cup bottom detection camera assembly 21 can be axially removed to achieve quick cleaning or replacement, making the operation simple.

[0039] like Figure 1 As shown, in an optional embodiment, the cup bottom detection mechanism 20 further includes a first light source support 261, which is sleeved on the first assembly rod 24 and adjustable circumferentially relative to the first assembly rod 24. The first light source 23 is mounted on the first light source support 261, and its height is adjusted by sliding the first light source support 261 on the first assembly rod 24. The first light source support 261 can also rotate circumferentially along the first assembly rod 24, causing the first light source 23 to rotate accordingly, so that after installation, the first light source 23 can rotate to the position corresponding to the paper cup detection station, simplifying operation.

[0040] like Figure 1As shown, in a specific embodiment, the first light source support 261 is provided with two second movable adjustment blocks 2611. The two second movable adjustment blocks 2611 surround and form a second assembly hole 2612 and a second gap 2613 communicating with the second assembly hole 2612. The second gap 2613 communicates with the outside, and the first assembly rod 24 can pass through the second assembly hole 2612. Each second movable adjustment block 2611 is provided with a second locking hole 26111. The axis of the second locking hole 26111 is set at an angle to the axis of the second assembly hole 2612. Screws are provided to pass through the second locking holes 26111 to be threadedly connected to the two second movable adjustment blocks 2611 respectively and to form a lock. In actual use, after the first light source support 261 rotates relative to the first assembly rod 24 at a certain angle to reach the desired position, the screws are tightened to make the two second movable adjustment blocks 2611 clamp the first assembly rod 24, thereby fixing the first light source support 261 relative to the first assembly rod 24.

[0041] like Figure 1 As shown, in a specific embodiment, the cup bottom detection mechanism 20 further includes a first light source adjustment component 262. The first light source adjustment component 262 is slidably connected to the end of the first light source support 261 away from the first assembly rod 24. The first light source adjustment component 262 is equipped with a first light source 23 to support the first light source 23 and drive the first light source 23 to move, thereby adjusting the position of the first light source 23 so that the first light source 23 can correspond to the position of the paper cup detection station.

[0042] like Figure 1 As shown, in an optional embodiment, the cup bottom detection mechanism 20 further includes a photomask assembly 27, which includes a cover 271. The cover 271 is mounted on the first light source support 261 and covers the first light source 23. This can reduce interference from external light, improve imaging quality, and help protect the first light source 23, reducing the adhesion of dust, impurities, etc. to avoid contaminating the first light source 23.

[0043] like Figure 1 As shown, in a specific embodiment, the cover 271 also covers the light input ends of the beam splitter 22 and the cup-bottom detection camera assembly 21. The cover 271 has a clearance opening 2711 through which the cup-bottom detection camera assembly 21 passes. The clearance opening 2711 facilitates the assembly of the beam splitter 22 and the cup-bottom detection camera assembly 21. Through the above configuration, the cover 271 can block external stray light from interfering with the beam splitter 22 and the cup-bottom detection camera assembly 21, reduce external light pollution, and protect the beam splitter 22 and the cup-bottom detection camera assembly 21, preventing dust and other impurities from adhering to them, thereby improving the accuracy and quality of imaging.

[0044] like Figure 1As shown, in a specific embodiment, the photomask assembly 27 further includes a support base plate 272 installed at the bottom of the cover 271. The support base plate 272 and the cover 271 together form a beam-splitting cavity 2701. The beam splitter 22 is installed on the bottom detection lens 212 and disposed inside the beam-splitting cavity 2701. The bottom detection camera assembly 21 passes through the beam-splitting cavity 2701. With this configuration, the support base plate 272 can isolate light interference from the bottom.

[0045] like Figure 1 As shown, in a specific embodiment, the cup bottom detection mechanism 20 further includes a dustproof component 28. The dustproof component 28 is located above the first light source 23 and is made of a transparent material. This allows it to maintain good light transmittance while preventing dust and impurities from falling from above the first light source 23 and adhering to it. The dustproof component 28 can be cleaned as needed to maintain light transmittance. For example, the dustproof component 28 can be made of materials such as glass or acrylic.

[0046] like Figure 3 As shown, in an optional embodiment, the paper cup detection device 100 further includes a cup rim detection mechanism 30, which is positioned above the paper cup detection station in the height direction to detect the quality of the paper cup rim. The paper cup detection device 100 is provided with a fixed panel for mounting the cup rim detection mechanism 30.

[0047] like Figure 3 As shown, in a specific embodiment, the support assembly 10 includes a second assembly plate 12 disposed above the paper cup detection station along the height direction.

The cup rim detection mechanism 30 is disposed above the second assembly plate 12 and passes through the through hole of the second assembly plate 12 to detect the rim of the paper cup at the paper cup detection station. The support assembly 10 also includes a support column 13 that is retractable along the height direction. The support column 13 is connected between the first assembly plate 11 and the second assembly plate 12 to provide support and can adjust the distance between the first assembly plate 11 and the second assembly plate 12 along the height direction.

In a specific embodiment, the cup rim detection camera assembly 33 includes a cup rim detection camera 331 and a cup rim detection lens 332 mounted on the cup rim detection camera 331.

[0049] like Figure 3As shown, in a specific embodiment, the cup rim detection mechanism 30 includes a second mounting rod 311 and a second camera support 312. The second camera support 312 is sleeved on the second mounting rod 311 and is adjustable relative to the second mounting rod 311 along the circumference of the second mounting rod 311. The cup rim detection camera assembly 33 is mounted on the second camera support 312, and the second camera support 312 can drive the cup rim detection camera assembly 33 to rotate along the circumference of the second mounting rod 311.

[0050] like Figure 3 As shown, in a specific embodiment, the second camera support 312 is provided with two third movable adjustment blocks 3121. The two third movable adjustment blocks 3121 surround and form a third mounting hole 3122 and a third gap 3123 communicating with the third mounting hole 3122. The third gap 3123 communicates with the outside, and the second mounting rod 311 can pass through the third mounting hole 3122. Each third movable adjustment block 3121 is provided with a third locking hole 31211. The axis of the third locking hole 31211 is set at an angle to the axis of the third mounting hole 3122. Screws are provided to pass through the third locking holes 31211 to be threadedly connected to the two third movable adjustment blocks 3121 respectively and to form a lock. In actual use, after the second camera support 312 rotates relative to the second mounting rod 311 to a certain angle to reach the desired position, the screws are tightened to make the two third movable adjustment blocks 3121 clamp the second mounting rod 311, thereby fixing the second camera support 312 relative to the second mounting rod 311.

[0051] like Figure 3 As shown, in a specific embodiment, the cup rim detection mechanism 30 further includes a third camera adjustment component 313. The third camera adjustment component 313 is slidably connected to the side of the second camera support 312 away from the second assembly rod 311. The third camera adjustment component 313 is equipped with a cup rim detection camera assembly 33. The third camera adjustment component 313 can drive the cup rim detection camera assembly 33 to move along the height direction to adjust the distance of the cup rim detection camera assembly 33 from the paper cup detection station in the height direction.

[0052] like Figure 3 As shown, in a specific embodiment, the cup rim detection mechanism 30 further includes a second light source 32, which is mounted on the second camera support 312 and located below the cup rim detection camera assembly 33 to illuminate the rim of the paper cup.

[0054] like Figure 3 As shown, this application also provides a paper cup forming system 1000, which includes a crimping device 200, a transmission device 400, and the aforementioned paper cup detection device 100. The crimping device 200 and the paper cup detection device 100 are spaced apart. The crimping device 200 has a crimping station for crimping the rim of the paper cup. The transmission device 400 can mount the paper cup and drive it from the crimping station to the paper cup detection station for inspection of the crimped paper cup. The aforementioned paper cup detection device 100 enables simultaneous detection of the cup rim and bottom, reduces the installation space occupied under the cup bottom, and facilitates the assembly of the cup bottom detection camera 211.

[0055] like Figure 3 As shown, in a specific embodiment, the paper cup forming system 1000 also includes an oiling device 300. The oiling device 300 is provided with an oiling station and can apply oil to the mouth of the paper cup to facilitate the subsequent edge rolling forming of the paper cup.
