Description

Technical Field

[0001] This application relates to the technical field of paper cup production, and particularly to a paper cup detection device. Background Art

[0002] With the wide application of disposable paper cups in the fields of food and beverage services, daily life, etc., the construction of the quality control system in the production process has become increasingly important. In the paper cup manufacturing process, the quality inspection link has become an indispensable key process. However, the current mainstream detection technology means in the industry have significant limitations, specifically manifested as follows:

[0003] 1. The existing line scan detection method requires a dedicated line scan detection platform to be built, with huge cost investment, complex equipment and cumbersome maintenance. At the same time, its detection efficiency is extremely low. It can only detect a single paper cup at a time, and can only complete the detection operation of a single paper cup each time. Its detection speed is seriously mismatched with the production capacity requirements of modern high-speed paper cup production lines, becoming the main bottleneck restricting the improvement of production process efficiency.

[0004] 2. The functions of current paper cup detection agencies are too single, and they can only detect the cup mouth and cup bottom of paper cups. For defects on the outer wall of paper cups, such as scratches and depressions that may appear on the outer wall surface, as well as key detection points such as the integrity and accuracy of the outer wall pattern, the existing detection agencies are completely powerless. This results in a large number of paper cups with outer wall defects flowing into the market, not only damaging the corporate brand image but also affecting the user experience of consumers.

[0005] In summary, the existing paper cup detection equipment has significant deficiencies in terms of detection efficiency and the coverage range of detection items, and it is difficult to meet the urgent needs of modern paper cup production lines for high-efficiency and comprehensive quality control. Summary of the Invention

[0006] Based on this, it is necessary to provide a paper cup detection device to address the problems of poor detection efficiency and small coverage range of detection items in the existing paper cup detection equipment.

[0007] A paper cup detection device, the paper cup detection device includes a first turret and an outer wall detection member for the cup. The first turret is rotatably arranged around a rotation axis. The first turret includes a plurality of cup suction stations that can independently control suction. The cup suction stations are used to adsorb paper cups arranged radially along the first turret. The outer wall detection member for the cup is located on the outer periphery of the first turret and on one side of the rotation path of the cup suction stations. The outer wall detection member for the cup is used to detect the outer peripheral surface of the paper cup located opposite the outer wall detection member for the cup. Wherein, the first turret is configured to pause rotating when rotating to different set angles, and when the first turret rotates to any set angle, one of the cup suction stations is opposite the outer wall detection member for the cup.

[0008] In one embodiment, the first turret includes a first turntable rotatably arranged about its own axis, and the suction cup stations are arranged radially and distributed at intervals on the circumferential surface of the first turntable.

The first cup mold is rotatably sleeved on the outer periphery of the first inner tube, and a first air hole communicating with the first air flow channel is formed in the end face of the first cup mold facing away from the first turntable.

[0010] In one embodiment, the first cup mold includes a connecting portion and a sleeve cup portion connected to each other. The connecting portion is located at one end of the first cup mold close to the first turntable, and the sleeve cup portion is located at one end of the first cup mold away from the first turntable. The sleeve cup portion is a structure imitating a paper cup.

[0011] In one embodiment, the diameter of the connecting portion is smaller than the diameter of the sleeve cup portion at the end close to the connecting portion.

[0012] In one embodiment, the paper cup detection device further includes a rotating assembly. The rotating assembly is located on the outer periphery of the first turret and on one side of the rotation path of the suction cup station. The rotating assembly is used to drive the first cup mold located opposite the cup outer wall detector to rotate about its own axis.

[0013] In one embodiment, the rotating assembly includes a rotatable friction wheel. The friction wheel is located on one side of the suction cup station opposite the cup outer wall detector, and the friction wheel is used to contact the circumferential surface of the connecting portion located opposite the cup outer wall detector to drive the first cup mold to rotate.

[0014] In one embodiment, the first turntable has an annular structure. The first inner tube penetrates the first turntable in the radial direction of the first turntable, and the axes of all the first inner tubes are in the same plane. The dimensions of all the first cup molds protruding from the first turntable in the axial direction of the first turntable are the same.

[0015] In one embodiment, the paper cup detection device further includes a mounting bracket. The mounting bracket is provided with a slide rail arranged parallel to the rotation axis of the first turret. The cup outer wall detection member can be slidably connected to the mounting bracket along the slide rail and then locked; and / or, the mounting bracket includes a column. The column is provided with a rotation groove and an arc groove arranged at intervals. The axial directions of both the rotation groove and the arc groove are parallel to the axial direction of the cup suction station opposite to the cup outer wall detection member. One end of the cup outer wall detection member is rotatably arranged in the rotation groove, and the other end can be slidably arranged along the arc groove and then locked.

At the same time, by arranging a plurality of cup suction stations with independently controllable suction forces on the outer periphery of the first turret, and making it such that when the first turret rotates to any set angle, one of the cup suction stations is opposite to the cup outer wall detection member, so that when the first turret pauses rotating each time, there is always a cup suction station opposite to the cup outer wall detection member, thus enabling the cup outer wall detection member to detect the corresponding paper cup every time the first turret pauses rotating, avoiding the cup outer wall detection member being idle and reducing the efficiency of paper cup detection.

[0034] Refer to Figure 1 , Figure 1 shows a schematic structural diagram of a paper cup detection device 100 in an embodiment of the present application. The paper cup detection device 100 provided in an embodiment of the present application is applied to the appearance quality detection of paper cups 200 during the production process of paper cups 200.

[0035] As Figure 1 shown, the paper cup detection device 100 includes a first turret 110 and a cup outer wall detection member 131. The first turret 110 is rotatably arranged around a rotation axis. Combining Figure 2 shown, the first turret 110 includes a plurality of suction cup stations 111 that can independently control suction. Combining Figure 3 shown, the suction cup station 111 is used to adsorb the paper cup 200 arranged radially along the first turret 110.

[0036] As Figure 1 shown, the cup outer wall detection member 131 is located on the outer periphery of the first turret 110 and on one side of the rotation path of the suction cup station 111. The cup outer wall detection member 131 is used to detect the outer peripheral surface of the paper cup 200 located opposite the cup outer wall detection member 131.

[0037] Among them, the first turret 110 is configured to pause rotating when rotating to different set angles. In this embodiment, the rotating mode of the first turret 110 is intermittent rotation, that is, the first turret 110 pauses after rotating a certain angle, and then pauses again after rotating a certain angle, and so on in a cycle. The angle of each rotation of the first turret 110 is related to the number of suction cup stations 111. For example, when there are four suction cup stations 111 on the first turret 110, the angle of each rotation of the first turret 110 is 90 degrees. When there are six suction cup stations 111 on the first turret 110, the angle of each rotation of the first turret 110 is 60 degrees. In this embodiment, there are 8 suction cup stations 111 on the first turret 110, and the angle of each rotation thereof is 45 degrees.

[0038] As Figure 1 shown, when the first turret 110 rotates to any set angle, one of the suction cup stations 111 is aligned with the cup outer wall detector 131, so that when the first turret 110 pauses each time it rotates, there is always a suction cup station 111 aligned with the cup outer wall detector 131, so that the cup outer wall detector 131 can detect the corresponding paper cup 200 every time the first turret 110 pauses, avoiding the inefficiency of paper cup 200 detection due to the idleness of the cup outer wall detector 131.

[0039] The intermittent rotation of the first turret 110 enables the suction cup station 111 to stay at the cup outer wall detector 131 for a certain period of time, facilitating the cup outer wall detector 131 to detect the outer peripheral surface of the paper cup 200. The cup outer wall detector 131 can be an industrial line array camera, which is used to photograph the outer peripheral surface of the paper cup 200, and then detect the outer peripheral surface of the paper cup 200 through image processing technology to determine whether there are defects on the outer peripheral surface of the paper cup 200, such as cracks, deformations, stains, etc.

[0040] As Figure 2 and Figure 4 shown, the first turret 110 is driven by a first driving member 116 exemplified by a servo motor. The servo motor is connected to the first turret 110 through a first reducer 114 and a first rotating shaft 113, and the servo motor is controlled by a controller. The controller controls the rotation of the servo motor according to a preset program, so that the first turret 110 pauses rotating when rotating to different set angles. As Figure 2 and Figure 4 shown, the first turret 110 is further provided with a connecting flange 115 to connect the first rotating shaft 113 and the first turntable 112 to make them rotate synchronously. The set angle of the first turret 110 corresponds to the number of suction cup stations 111. In this embodiment, both the set angle and the number of suction cup stations 111 are 8, and the angle difference between adjacent set angles is 45 degrees, which are 0 degrees, 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees and 315 degrees respectively.

[0041] In this embodiment, the paper cup detection device 100 further includes a cup separating device 190. The cup separating device 190 is located on one side of the first turret 110 and is used to convey the paper cup 200 to the cup sucking station 111 of the first turret 110. As Figure 1 shown, in this embodiment, the cup separating device 190 is located above the first turret 110, and the paper cup 200 can fall from the cup separating device 190 to the cup sucking station 111 corresponding to the cup separating device 190.

[0042] As Figure 2 shown, in one embodiment, the first turret 110 includes a first turntable 112 rotatably arranged about its own axis. The cup sucking stations 111 are arranged radially and are spaced apart on the circumferential surface of the first turntable 112. The angular difference between adjacent cup sucking stations 111 and the set angle of the first turret 110 is the same, so that each rotation of the first turret 110 exactly makes the next cup sucking station 111 correspond to the cup outer wall detection member 131.

[0043] As Figure 4 shown, in one embodiment, each cup sucking station 111 includes a first inner tube 1111 and a first cup mold 1112. The first inner tube 1111 is arranged radially along the first turntable 112 and is internally provided with a first air flow channel 11111. The first air flow channel 11111 is communicated with an external air source. By controlling the positive pressure or negative pressure of the air source, the adsorption or release of the paper cup 200 can be realized. The air source can be a vacuum pump or a compressed air source. The first turntable 112 further includes a first air distribution plate 117 to flow the air flow in the external air source to the first air flow channel 11111 of each cup sucking station 111.

[0044] As Figure 4 shown, the first cup mold 1112 is rotatably sleeved on the outer periphery of the first inner tube 1111. The rotatable design of the first cup mold 1112 enables the paper cup 200 to rotate during the detection process, facilitating the detection of the entire outer circumferential surface of the paper cup 200 by the cup outer wall detection member 131. In this embodiment, a bearing 1113 is provided between the first cup mold 1112 and the first inner tube 1111 to realize the rotation of the first cup mold 1112 relative to the first inner tube 1111.

[0045] Combined with Figure 6 shown, a first air hole 11123 communicated with the first air flow channel 11111 is formed on the end surface of the first cup mold 1112 facing away from the first turntable 112. When a negative pressure is formed in the first air flow channel 11111, suction force is generated at the air hole, and the paper cup 200 can be adsorbed; when a positive pressure is formed in the first air flow channel 11111, a thrust is generated at the first air hole 11123, and the paper cup 200 can be released.

[0046] As Figure 2 andFigure 4 As shown, in one embodiment, the first cup mold 1112 includes a connecting portion 11121 and a cup-mounting portion 11122 that are connected to each other. The connecting portion 11121 is located at one end of the first cup mold 1112 close to the first turntable 112. The inner diameter of the connecting portion 11121 is slightly larger than the outer diameter of the first inner tube 1111, so that the connecting portion 11121 can be mounted on the first inner tube 1111 and can rotate relative to the first inner tube 1111.

[0047] like Figure 2 and Figure 4 As shown, the cup-covering portion 11122 is located at one end of the first cup mold 1112 away from the first turntable 112, and the cup-covering portion 11122 is a structure that imitates the paper cup 200, that is, the outer wall shape of the cup-covering portion 11122 matches the inner wall shape of the paper cup 200, as shown in FIG. Figure 3 As shown, the paper cup 200 can be stably mounted on the first cup mold 1112 without shaking or falling off.

[0048] like Figure 2 and Figure 4 As shown, in one embodiment, the connecting portion 11121 is a cylindrical structure, and the diameter of the connecting portion 11121 is smaller than the diameter of the cup portion 11122 near one end of the connecting portion 11121, so as to facilitate the subsequent rotating component 170 to contact the connecting portion 11121 and drive the first cup mold 1112 to rotate.

[0049] like Figure 5 As shown, in one embodiment, the paper cup detection device 100 further includes a rotating assembly 170, which is located on the outer periphery of the first turret 110 and on one side of the rotation path of the cup suction station 111. In this embodiment, the rotating assembly is located on the side of the cup suction station 111 away from the cup outer wall detection member 131 to avoid the rotating assembly interfering with the judgment of the appearance of the paper cup 200 by the cup outer wall detection member 131. The rotating assembly 170 is used to drive the first cup mold 1112 located at the cup outer wall detection member 131 to rotate around its own axis, so that the paper cup 200 can rotate during the detection process, which is convenient for the cup outer wall detection member 131 to detect the entire outer peripheral surface of the paper cup 200. In other embodiments, the cup outer wall detection member 131 can also be rotated to achieve the detection of the entire outer peripheral surface of the paper cup 200 by the cup outer wall detection member 131.

[0050] like Figure 5As shown, in one embodiment, the rotating assembly 170 includes a rotatable friction wheel 171. The friction wheel 171 is located on one side of the cup suction station 111 opposite to the cup outer wall detector 131, and the friction wheel 171 is used to contact the circumferential surface of the connecting portion 11121 of the cup outer wall detector 131 to drive the first cup mold 1112 to rotate through friction. The material of the friction wheel 171 can be selected as a material with a relatively high friction coefficient, such as rubber, to increase the friction force and ensure that the first cup mold 1112 can be effectively driven to rotate. The position of the friction wheel 171 can be adjusted according to the position of the first cup mold 1112 to ensure that the friction wheel 171 can be in full contact with the connecting portion 11121 of the first cup mold 1112. At the same time, the pressure of the friction wheel 171 can also be adjusted to ensure that the friction force is large enough to effectively drive the first cup mold 1112 to rotate.

[0051] As Figure 5 shown, the rotating assembly 170 further includes a third driving member 172, a driving transmission member 173, a driven transmission member 174, and a rotating member 175. Among them, the third driving member 172 is used to drive the driving transmission member 173 to rotate. The driven transmission member 174 is in transmission connection with the driving transmission member 173, and the driven transmission member 174 is coaxially arranged with the friction wheel 171 and rotates synchronously. The rotating member 175 is used to fix the position of the friction wheel 171 in its own axial direction to prevent the friction wheel 171 from moving axially or radially on the first turntable 112 and interfering with the rotation of the cup suction station 111 or damaging the cup suction station 111. In this embodiment, both the driven transmission member 174 and the driving transmission member 173 are rotating wheels, and the two are connected by a transmission belt. In other embodiments, the driven transmission member 174 and the driving transmission member 173 can also adopt other transmission methods, such as gear transmission.

[0052] As Figure 2 shown, in one embodiment, the first turntable 112 has an annular structure, that is, the central part of the first turntable 112 is hollow to facilitate the installation of the first inner tube 1111. The first inner tube 1111 penetrates the first turntable 112 in the radial direction of the first turntable 112, that is, one end of the first inner tube 1111 is located inside the first turntable 112, and the other end is located outside the first turntable 112. This design enables the internal air flow channel of the first inner tube 1111 to communicate with the air source inside the first turntable 112, and at the same time, the outer end of the first inner tube 1111 can be installed with the first cup mold 1112. At the same time, it is also possible to limit the installation of the cup suction station 111 through the first turntable 112, limit the jumping range of the first cup mold 1112 during rotation, and further avoid violent jumping when the first cup mold 1112 contacts the rotating assembly 170, thereby reducing the impact on the first rotating shaft 113 and alleviating the vibration of the entire device to ensure the accuracy of the outer wall detection image.

[0053] As Figure 2and Figure 3 As shown, the axes of all the first inner tubes 1111 are in the same plane, and the dimensions by which all the first cup molds 1112 protrude axially from the first turntable 112 are the same, so that the heights of all the cup sucking stations 111 are the same, which is convenient for the installation and adjustment of the rotating assembly 170, and avoids different rotating effects of the rotating assembly 170 on different first cup molds 1112 due to inconsistent protruding dimensions of different first cup molds 1112. At the same time, in this embodiment, the first turntable 112 and the cup sucking stations 111 can be used as a pre-assembled whole and then connected to the first rotating shaft 113, etc. At this time, it is convenient to adjust the assembly accuracy between all the first cup molds 1112 connected to the first turntable 112 and the first turntable 112, thereby restricting the jumping range of the first cup molds 1112, and further avoiding severe jumping when the first cup molds 1112 contact the rotating assembly 170, thereby slowing down the impact on the first rotating shaft 113 and alleviating the vibration of the entire device to ensure the accuracy of the outer wall detection image.

[0054] As Figure 6 shown, in one embodiment, the paper cup detection device 100 includes a cup outer wall detection assembly 130. The cup outer wall detector 131 includes a cup outer wall detector 131 and a mounting bracket 132. The mounting bracket 132 is used to support the cup outer wall detector 131. The mounting bracket 132 is provided with a slide rail 1321 arranged parallel to the rotation axis of the first turret 110. The cup outer wall detector 131 can be slidably connected to the mounting bracket 132 along the slide rail 1321 and then locked. The cup outer wall detector 131 can be connected to the slide rail 1321 through a slider, can slide along the slide rail 1321, adjust the distance between the cup outer wall detector 131 and the first turret 110, and then be locked in a suitable position through the first fastener 1323. So that the position of the cup outer wall detector 131 can be adjusted as needed to adapt to paper cups 200 of different specifications or different detection requirements, and it is convenient to adjust the focus of the cup outer wall detector 131.

[0055] As Figure 6 shown, in one embodiment, the mounting bracket 132 includes a column 1322. The column 1322 is provided with a rotation groove 13221 and an arc groove 13222 arranged at intervals. The axial directions of the rotation groove 13221 and the arc groove 13222 are both parallel to the axial direction of the cup sucking station 111 opposite to the cup outer wall detector 131. One end of the cup outer wall detector 131 is rotatably arranged in the rotation groove 13221, and the other end can be slidably arranged along the arc groove 13222 and then locked through the third fastener 1325, so that the cup outer wall detector 131 can rotate around the second fastener 1324 in the rotation groove 13221 to adjust the angle of the cup outer wall detector 131 to adapt to different detection requirements.

[0056] As Figure 6As shown, in one embodiment, the mounting bracket 132 further includes a fixing plate 1326 and a mounting rotating shaft 1327. Among them, the slide rail 1321 and the column 1322 are both connected to the fixing plate 1326, and the fixing plate 1326 is rotatably connected to the mounting rotating shaft 1327, so that the fixing plate 1326, as well as the slide rail 1321, the column 1322 and the cup outer wall detection member 131 mounted on the fixing plate 1326, can rotate around the mounting rotating shaft 1327, thereby adjusting the orientation of the cup outer wall detection member 131.

[0057] As Figure 6 shown, in one embodiment, the paper cup detection device 100 further includes an illumination assembly 180. The illumination assembly 180 is located on the outer periphery of the first turret 110 and on one side of the rotation path of the cup suction station 111. The illumination assembly 180 includes a light source 181 disposed toward the paper cup 200 opposite to the cup outer wall detection member 131. The light source 181 can be a linear light source, and the emitted light is a long and narrow rectangular area, which is used to provide sufficient light for the cup outer wall detection member 131 to ensure that the cup outer wall detection member 131 can clearly capture the outer peripheral surface of the paper cup 200.

[0058] As Figure 6 shown, the illumination assembly 180 further includes an optical axis bracket 182. The light source 181 is detachably connected to the optical axis bracket 182, and the position and orientation of the light source 181 can be adjusted according to the position of the cup suction station 111 to ensure that the light source 181 can fully irradiate the outer peripheral surface of the paper cup 200.

[0059] Preferably, the brightness of the illumination assembly 180 can be adjusted according to the detection requirements. For example, when it is necessary to detect the fine defects on the outer peripheral surface of the paper cup 200, the brightness of the illumination assembly 180 can be increased to improve the clarity of the image; when only the obvious defects on the outer peripheral surface of the paper cup 200 need to be detected, the brightness of the illumination assembly 180 can be appropriately reduced to reduce energy consumption.

[0060] As Figures 1 to 5 shown, in one embodiment, the cup suction station 111 is a positive cup suction station. The cup suction station 111 is used to adsorb the paper cup 200 with the cup mouth facing the direction of the axis of the first turret 110. The positive cup suction station means that the cup mouth of the paper cup 200 adsorbed by the cup suction station 111 faces the direction of the axis of the first turret 110. This design makes the bottom of the paper cup 200 face outward, which is convenient for the cup outer wall detection member 131 to detect the bottom and outer peripheral surface of the paper cup 200. Specifically, the positive cup suction station can be realized by the first cup mold 1112. The shape of the first cup mold 1112 imitates the bottom and the lower outer peripheral surface of the paper cup 200, so that the paper cup 200 can be stably placed on the first cup mold 1112, and the cup mouth faces the direction of the axis of the first turret 110.

[0061] It can be understood that when the outer cup wall detection member 131 detects the outer peripheral surface of the paper cup 200, there is no restriction on the orientation of the cup mouth of the paper cup 200. Therefore, in other embodiments, the cup sucking station 111 can also be opposite to the positive cup sucking station 111. For example, the orientation setting of the reverse cup sucking station 121 described below has no influence on the detection of the outer peripheral surface of the paper cup 200 by the outer cup wall detection member 131. However, in this specification, the cup sucking station 111 is still described as the positive cup sucking station 111 as shown in Figures 1 to 5 , but this is not a limitation.

[0062] As Figure 1 shown, in one embodiment, the paper cup detection device 100 further includes a cup bottom detection member 150. The cup bottom detection member 150 is located on the outer periphery of the rotation path of the positive cup sucking station 111. When the first turret 110 rotates to any set angle, one of the positive cup sucking stations 111 is aligned with the cup bottom detection member 150, so that when the first turret 110 stops rotating at any preset angle, the cup bottom detection member 150 can detect the cup bottom of the corresponding paper cup 200, avoiding the idle state of the cup bottom detection member 150 and reducing the detection efficiency. Since the cup bottom of the paper cup 200 adsorbed by the positive cup sucking station 111 faces outward, the cup bottom detection member 150 is arranged facing the positive cup sucking station 111, that is, the shooting direction of the cup bottom detection member 150 faces the positive cup sucking station 111, so as to detect the bottom surface of the paper cup 200 aligned with the cup bottom detection member 150. The cup bottom detection member 150 can be an industrial area array camera, which is used to shoot the bottom surface of the paper cup 200, and then detect the bottom surface of the paper cup 200 through image processing technology to judge whether there are defects on the bottom surface of the paper cup 200, such as cracks, deformations, stains, etc. It should be noted that in Figure 1 , although the cup bottom detection member 150 is shown downstream of the outer cup wall detection member 131, this is not a limitation. The two independently judge whether the paper cup 200 is a defective product. In other embodiments, the cup bottom detection member 150 can also be upstream of the outer cup wall detection member 131.

[0063] As Figure 1 shown, in one embodiment, the paper cup detection device 100 further includes a material receiving assembly 160. The material receiving assembly 160 includes a first waste cup recycling device 161. The first waste cup recycling device 161 is on the rotation path of the cup sucking station 111. The first waste cup recycling device 161 is downstream of the outer cup wall detection member 131. The first waste cup recycling device 161 is located on the outer periphery of the rotation path of the cup sucking station 111. When the first turret 110 rotates to any set angle, one of the cup sucking stations 111 is aligned with the first waste cup recycling device 161. The first waste cup recycling device 161 is used to collect the defective products in the paper cup 200 aligned with the first waste cup recycling device 161. In this embodiment, the first waste cup recycling device 161 is downstream of the outer cup wall detection member 131 and the cup bottom detection member 150.

[0064] After the outer wall inspection member 131 of the cup inspects the outer peripheral surface of the paper cup 200, if the inspection result shows that the paper cup 200 is a defective product, then when the paper cup 200 rotates to the first waste cup recycling device 161 with the first turret 110, the first turret 110 will control the corresponding cup suction station 111 to stop sucking, and blow air to make the paper cup 200 come out of the first cup mold 1112 and enter the waste cup recycling pipeline, so that the defective paper cup 200 falls into the first waste cup recycling device 161.

[0065] The position of the first waste cup recycling device 161 can be adjusted as needed. For example, the first waste cup recycling device 161 can be arranged downstream of the outer wall inspection member 131 of the cup, or downstream of the bottom inspection member 150 of the cup, or downstream of the cup mouth inspection member 140 of the cup. In this way, whether the paper cup 200 has defects on the outer peripheral surface, or on the bottom surface, or on the cup mouth, can be recycled in time.

[0066] As Figure 1 shown, in one of the embodiments, the paper cup inspection device 100 further includes a second turret 120. The second turret 120 is rotatably arranged around its own axis, and the first turret 110 and the second turret 120 are arranged at intervals and their axes are parallel. Combining Figure 7 and Figure 8 shown, the second turret 120 includes a plurality of anti-suction cup stations 121 that can independently control the suction force. The anti-suction cup stations 121 are used to suck the paper cup 200 with the cup mouth facing away from the axis direction of the second turret 120, that is, the cup mouth of the paper cup 200 faces outward.

[0067] The second turret 120 is configured to pause rotating when rotating to different preset angles. The second turret 120 also rotates intermittently, that is, the second turret 120 rotates a certain angle and then pauses, and then rotates a certain angle and pauses again, and so on in a cycle. The angle of each rotation of the second turret 120 is related to the number of anti-suction cup stations 121. In this embodiment, taking the example that there are four anti-suction cup stations 121 arranged on the second turret 120, at this time, the angle of each rotation of the second turret 120 is 90 degrees.

[0068] When the second turret 120 rotates to any preset angle, at least one reverse suction cup station 121 is disposed opposite to one of the positive suction cup stations 111 when the first turret 110 is at a set angle, so that the paper cup 200 can be transferred from the positive suction cup station 111 on the first turret 110 to the reverse suction cup station 121 on the second turret 120, or from the reverse suction cup station 121 on the second turret 120 to the positive suction cup station 111 on the first turret 110. In this embodiment, on the flow path of the paper cup 200, the second turret 120 is downstream of the first turret 110. Therefore, the paper cup 200 is transferred from the positive suction cup station 111 on the first turret 110 to the reverse suction cup station 121 on the second turret 120.

[0069] As Figure 7 and Figure 8 shown, in one embodiment, the second turret 120 includes a second turntable 122 rotatably disposed about its own axis. The reverse suction cup stations 121 are arranged radially and distributed at intervals on the circumferential surface of the second turntable 122. In this embodiment, when there are four reverse suction cup stations 121 on the second turntable 122, the four reverse suction cup stations 121 can be evenly distributed on the circumferential surface of the second turntable 122, and the angle between two adjacent reverse suction cup stations 121 is 90 degrees. In this embodiment, since the second turret 120 is downstream of the first turret 110, and in the first turret 110, due to defects in the cup bottom or the outer wall of the paper cup 200, the defective products can be timely removed from the detection process through the first waste cup recycling device 161, so that the number of reverse suction cup stations 121 in the second turret 120 can be less than the number of suction cup stations 111 in the first turret 110. Moreover, in this embodiment, the number of reverse suction cup stations 121 in the second turret 120 is 4, and also because during the rotation of the second turret 120, only the following 4 functions need to be completed: 1. Transfer the paper cup 200 between the first turret 110 and the second turret 120, 2. Detect the cup mouth and the inside of the paper cup 200, 3. Recycle the waste cup, 4. Discharge the non-defective paper cup 200.

[0070] As Figure 7 and Figure 8 shown, the second turret 120 is driven by a second driving member 123 such as a servo motor. The servo motor is connected to the second turret 120 through a second speed reducer 124 and a second rotating shaft 125. The servo motor is controlled by a controller, and the output shaft of the stepping motor is connected to the second rotating shaft 125 through a coupling 127. The controller controls the rotation of the servo motor according to a preset program, so that the second turret 120 pauses rotating when it rotates to different set angles. As Figure 2 and Figure 4 shown, the second turret 120 is further provided with a flange seat 128 to fixedly install the second turret 120 through the flange seat 128.

[0071] As Figure 7 and Figure 8 shown, each anti-suction cup station 121 includes a second inner tube 1211 and a second cup mold 1212. The second inner tube 1211 is arranged along the radial direction of the second turntable 122 and is internally provided with a second air flow channel 12111. The second air flow channel 12111 is communicated with an external air source. By controlling the positive pressure or negative pressure of the air source, the adsorption or release of the paper cup 200 can be realized. The air source can be a vacuum pump or a compressed air source. The second turntable 122 further includes a second air distribution plate 126 to flow the air flow in the external air source to the second air flow channels 12111 of each suction cup station 111. The end face of the second cup mold 1212 facing away from the second turntable 122 is provided with a second air hole ( Figure 7 not visible in the figure and not marked) communicated with the second air flow channel 12111. When a negative pressure is formed in the second air flow channel 12111, suction force is generated at the air hole, and the paper cup 200 can be adsorbed; when a positive pressure is formed in the second air flow channel 12111, a thrust is generated at the second air hole, and the paper cup 200 can be released.

[0072] As Figure 1 shown, in one embodiment, the paper cup detection device 100 further includes a cup mouth detection member 140. The cup mouth detection member 140 is located on the outer periphery of the rotation path of the anti-suction cup station 121. When the second turret 120 rotates to any preset angle, one of the suction cup stations 111 is aligned with the cup mouth detection member 140, so that at any preset angle when the second turret 120 stops rotating, the cup mouth detection member 140 can detect the cup mouth and the inside of the corresponding paper cup 200, avoiding the idleness of the cup mouth detection member 140 and reducing the detection efficiency. Since the cup mouth of the paper cup 200 adsorbed by the anti-suction cup station 121 faces outward, the cup mouth detection member 140 is arranged facing the anti-suction cup station 121, that is, the shooting direction of the cup mouth detection member 140 faces the anti-suction cup station 121, for detecting the cup mouth and / or the inside of the paper cup 200 aligned with the cup mouth detection member 140. The cup mouth detection member 140 can be an industrial area array camera, which is used to shoot the cup mouth and the inside of the paper cup 200, and then detect the cup mouth and the inside of the paper cup 200 through image processing technology to judge whether there are defects such as cracks, deformations, stains, etc. in the cup mouth and the inside of the paper cup 200.

[0073] The material receiving assembly 160 includes a second waste cup recycling device 162. The second waste cup recycling device 162 is on the rotation path of the anti-suction cup station 121, downstream of the cup mouth detector 140, and located on the outer periphery of the rotation path of the anti-suction cup station 121. When the second turret 120 rotates to any set angle, one of the anti-suction cup stations 121 is aligned with the second waste cup recycling device 162. The second waste cup recycling device 162 is used to collect defective products in the paper cup 200 aligned with the second waste cup recycling device. In this embodiment, the second waste cup recycling device 162 is downstream of the cup mouth detector 140.

[0074] The material receiving assembly 160 includes a finished product collecting device 163. The finished product collecting device 163 is on the rotation path of the anti-suction cup station 121, downstream of the cup outer wall detector 131, the cup bottom detector 150, and the cup mouth detector 140. The finished product collecting device 163 is located on the outer periphery of the rotation path of the anti-suction cup station 121. When the second turret 120 rotates to any set angle, one of the anti-suction cup stations 121 is aligned with the finished product collecting device 163. The finished product collecting device 163 is used to collect good products in the paper cup 200 aligned with the finished product collecting device 163.

[0075] When the paper cup detecting device 100 provided in this application is working: the cup separating device 190 releases the paper cups 200 one by one. The cup suction station 111 in the first turret 110 that is aligned with the cup separating device 190 sucks the paper cup 200, so that the paper cup 200 is fixed at the cup suction station 111. Subsequently, the first turret 110 rotates. Figure 1 From the perspective shown, the first turret 110 rotates counterclockwise. In this embodiment, when the first turntable 112 rotates 90 degrees, when the cup suction station 111 rotates to be aligned with the cup outer wall detector 131, under the illumination of the lighting assembly 180, the friction wheel 171 of the rotating assembly 170 contacts the first cup mold 1112 of the cup suction station 111 to drive the first cup mold 1112 to rotate, thereby driving the paper cup 200 sleeved outside the first cup mold 1112 to rotate synchronously. The cup outer wall detector 131 detects the rotating paper cup 200 to determine whether there are defects on the outer wall of the paper cup 200. After that, the first turret 110 continues to rotate. In this embodiment, after the first turntable 112 rotates 45 degrees, the cup suction station 111 is aligned with the cup bottom detector 150, and the cup bottom detector 150 performs a cup bottom detection on the paper cup 200. Then the first turret 110 continues to rotate. In this embodiment, after the first turret 110 rotates 45 degrees, the cup suction station 111 is aligned with the first waste cup recycling device 161, and the defective products in the paper cup 200 detected by the cup outer wall detector 131 and the cup bottom detector 150 are recycled.

[0076] Then the first turntable 112 continues to rotate. In this embodiment, after the first turntable 112 rotates 90 degrees, the cup suction station 111 faces the anti-cup suction station 121 of the second turret 120. The cup suction station 111 stops blowing air and changes to sucking air, while the anti-cup suction station 121 blows air. Then, the position of the paper cup 200 sleeved on the cup suction station 111 switches to the corresponding anti-cup suction station 121. After that, the second turntable 122 rotates. In the perspective as Figure 1 shown, the second turntable 122 rotates counterclockwise.

[0077] In this embodiment, when the second turntable 122 rotates 90 degrees, the anti-cup suction station 121 faces the cup mouth detector 140. At this time, the cup mouth detector 140 detects the cup mouth and the inside of the paper cup 200 on the anti-cup suction station 121. After the detection is completed, the second turntable 122 continues to rotate. In this embodiment, after the second turntable 122 rotates 90 degrees, the anti-cup suction station 121 faces the second waste cup recycling device 162, and the defective products in the paper cup 200 detected by the cup mouth detector 140 are recycled. If the paper cup 200 is a defective product, the paper cup 200 enters the second waste cup recycling device 162. The second turntable 122 continues to rotate. In this embodiment, after the second turntable 122 rotates 90 degrees, the anti-cup suction station 121 faces the finished product collection device 163. If the paper cup 200 is a non-defective product, the paper cup 200 enters the finished product collection device 163. So far, the detection of the outer wall, bottom, cup mouth and inside of one paper cup 200 is completed. By repeating this cycle, the detection of different paper cups 200 is realized.

[0078] In the paper cup detection device 100 provided in the above solution, by arranging the cup suction station 111 in the circumferential direction of the first turret 110 and arranging the outer wall detector 131 on the outer circumference of the first turret 110, the detection of the outer wall of the paper cup 200 is realized, enriching the functions of the existing paper cup 200 detection, filling the blank of the existing paper cup 200 for outer wall detection, and enabling the comprehensive detection of the defects of the outer wall and the outer wall pattern of the cup, further improving the comprehensiveness and accuracy of the detection. At the same time, by arranging a plurality of cup suction stations 111 with independently controllable suction forces on the outer circumference of the first turret 110, and making one of the cup suction stations 111 face the outer wall detector 131 when the first turret 110 rotates to any set angle, so that when the first turret 110 pauses each time it rotates, there is always a cup suction station 111 facing the outer wall detector 131, so that the outer wall detector 131 can detect the corresponding paper cup 200 every time the first turret 110 pauses, avoiding the idleness of the outer wall detector 131 and reducing the detection efficiency of the paper cup 200.

[0079] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0080] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
