Description

Technical Field

[0001] The utility model belongs to the field of mechanical manufacturing, and particularly relates to a paper cup turning device and a paper cup detector. Background Art

[0002] A paper cup detector is a device used for automatically inspecting the quality and specifications of paper cups. It is usually used in a paper cup production line to ensure that the paper cups meet the design requirements and quality standards.

[0003] In order to ensure the comprehensiveness of paper cup detection, a paper cup turning device is often provided in a paper cup detector to turn the paper cup so as to achieve comprehensive detection of both ends of the cup mouth and the cup bottom of the paper cup; the prior art mainly grabs the paper cup through a robotic arm to achieve the turning of the paper cup, but this method involves multiple steps such as grasping, picking up, turning, and placing, which is rather cumbersome and has low efficiency. Summary of the Utility Model

[0004] The purpose of the embodiment of the utility model is to provide a paper cup turning device, aiming to solve the problem of low efficiency in turning paper cups by existing paper cup detectors.

[0005] The embodiment of the utility model is implemented as follows. A paper cup turning device is provided and is arranged on a paper cup detector. The paper cup turning device includes:

[0006] A bracket, which is arranged on the paper cup detector;

[0007] A driving motor, which is arranged on the bracket;

[0008] A rotating body, which is mounted on the bracket. The rotating body is wheel-shaped and has a cavity inside. A first through hole is formed in the arc-shaped wheel surface of the rotating body. The rotating body is connected to the driving motor and rotates around the side axis under the drive of the driving motor;

[0009] An air extraction pipe, which is arranged on the bracket. An air passage is provided between the air extraction pipe and the side axis of the rotating body to connect the air extraction pipe with the cavity, and the air extraction pipe is connected to an external air extractor. After the air extractor is started, the air in the cavity of the rotating body is extracted through the air extraction pipe to form a negative pressure. When the cup mouth of the paper cup falls on the position of the first through hole on the surface of the rotating body, the negative pressure adsorbs the paper cup on the rotating body, and the driving motor drives the rotating body to rotate, thereby realizing the turning of the paper cup.

[0010] Preferably, the bracket includes two supports and a cylindrical barrel with one end open. The cylindrical barrel penetrates the rotating body from the side axis of the rotating body and is mounted between the two supports. A first bearing and a second bearing are provided on the cylindrical barrel. The rotating body is connected to the cylindrical barrel through the first bearing and the second bearing, so that the rotating body rotates around the cylindrical barrel under the action of an external force.

[0011] Preferably, a first pulley is provided at the output end of the drive motor, and a second pulley is coaxially arranged on the side surface of the rotating body. The first pulley and the second pulley are connected by a belt. When the drive motor is started, the rotating body rotates around the cylinder through the transmission of the first pulley, the belt, and the second pulley.

[0012] Preferably, the air extraction pipe extends into the cylinder from the open end of the cylinder, and a second through hole is formed in the cylinder wall inside the cavity, thereby forming an air passage between the air extraction pipe and the cavity, enabling the gas in the cavity to enter the air extraction pipe through the second through hole and then be extracted by the air extractor.

[0013] Preferably, a shielding member is further provided on the cylinder wall inside the cavity. One end of the shielding member is fixedly connected to the cylinder wall, and the other end is set to be in a shape adapted to the inner wall arc surface of the rotating body, for shielding the first through hole on the rotating body. When the first through hole rotates with the rotating body to the position where the shielding member is located, the shielding member blocks the first through hole, stopping the adsorption effect of the first through hole on the paper cup and causing the paper cup to fall off the rotating body.

[0014] Another embodiment of the present utility model provides a paper cup detection machine, which includes:

[0015] A detection machine body;

[0016] A first conveying mechanism, arranged on the detection machine body, for feeding the paper cups;

[0017] A first vision mechanism, arranged on the detection machine body;

[0018] The described paper cup flipping device, arranged on the detection machine body. When the paper cup is conveyed by the first conveying mechanism to the paper cup flipping device, one end of the paper cup is adsorbed by the paper cup flipping device, and then the paper cup flipping device rotates the paper cup by a first angle, making the other end of the paper cup face the first vision mechanism, so that the first vision mechanism can collect an image of the non-adsorbed end of the paper cup.

[0019] A second conveying mechanism, arranged on the detection machine body;

[0020] A second vision mechanism, arranged on the detection machine body. After the first vision mechanism completes image acquisition, the paper cup flipping device further rotates by a second angle and then stops adsorbing the paper cup, and the paper cup falls off. Moreover, the non-adsorbed end of the paper cup lands on the second conveying mechanism. Under the conveyance of the second conveying mechanism, the paper cup moves to a position facing the second vision mechanism, enabling the second vision mechanism to collect an image of the other end of the paper cup.

[0021] A blanking mechanism, arranged on the detection machine body, for blanking the detected paper cups.

[0022] A paper cup flipping device provided by an embodiment of the present utility model includes a bracket, which is arranged on a paper cup detector; a driving motor, which is arranged on the bracket; a rotating body, which is mounted on the bracket. The rotating body is wheel-shaped and has a cavity inside. A first through hole is formed on the arc-shaped wheel surface of the rotating body. The rotating body is connected to the driving motor and rotates around the side axis under the drive of the driving motor; an air extraction pipe, which is arranged on the bracket. An air passage is provided between the air extraction pipe and the side axis of the rotating body to connect the air extraction pipe with the cavity, and the air extraction pipe is connected to an external air extractor. In this application, after the air extractor is started, the air in the cavity of the rotating body is extracted through the air extraction pipe to form a negative pressure. When the cup mouth of the paper cup falls at the position of the first through hole on the surface of the rotating body, the negative pressure adsorbs the paper cup on the rotating body, and the driving motor drives the rotating body to rotate, thereby realizing the flipping of the paper cup. The flipping process is simple and fast, greatly improving the flipping efficiency of the paper cup, and further enhancing the overall efficiency of paper cup detection.

[0030] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0031] The following describes in detail the specific implementation of the present utility model in conjunction with specific embodiments.

[0032] As Figure 1 shown, a paper cup flipping device provided by an embodiment of the present utility model is arranged on a paper cup detector, and the paper cup flipping device includes:

[0033] A bracket 1, arranged on the paper cup detector;

[0034] A driving motor 2, arranged on the bracket 1;

[0035] A rotating body 3, mounted on the bracket 1. The rotating body 3 is wheel-shaped and has a cavity inside. A first through hole 31 is formed in the arc-shaped wheel surface of the rotating body 3. The rotating body 3 is connected to the driving motor 2, and under the drive of the driving motor 2, the rotating body 3 rotates around the side axis.

[0036] An air extraction pipe 4, arranged on the bracket 1. An air passage is provided between the air extraction pipe 4 and the side axis of the rotating body 3 to connect the air extraction pipe 4 with the cavity. The air extraction pipe 4 is connected to an external air extractor. After the air extractor is started, the air in the cavity of the rotating body 3 is extracted through the air extraction pipe 4 to form a negative pressure. When the cup mouth of the paper cup falls on the position of the first through hole 31 on the surface of the rotating body 3, the negative pressure adsorbs the paper cup on the rotating body 3, and the driving motor 2 drives the rotating body 3 to rotate, thereby realizing the flipping of the paper cup.

[0037] In this embodiment, a plurality of first through holes 31 are provided and are evenly arranged along the entire circumference of the arc-shaped wheel surface of the rotating body 3, so that the entire arc-shaped wheel surface of the rotating body 3 can adsorb the paper cup, that is, multiple paper cups can be adsorbed and flipped simultaneously. And the rotating body 3 is constantly rotating. After the paper cup is flipped in place and falls off the rotating body 3, the rotating body 3 rotates back to the paper cup feeding position, and then new paper cups can be adsorbed. The entire flipping process is simple. After the adsorbed paper cups are flipped, new paper cups can be quickly adsorbed and flipped, and multiple paper cups can be flipped simultaneously, greatly improving the flipping efficiency of the paper cup, and thus improving the overall efficiency of paper cup detection.

[0038] As Figure 2As shown, as a preferred embodiment, the bracket 1 includes two supports 11 and a cylinder 12 with an open end. The cylinder 12 penetrates through the side axis of the rotating body 3 and is mounted between the two supports 11. A first bearing 121 and a second bearing 122 are provided on the cylinder 12. The rotating body 3 is connected to the cylinder 12 through the first bearing 121 and the second bearing 122, so that the rotating body 3 rotates around the cylinder 12 under the action of an external force.

[0039] A first belt pulley 21 is provided at the output end of the driving motor 2. A second belt pulley is coaxially arranged on the side of the rotating body 3. The first belt pulley 21 and the second belt pulley are connected by a belt 22. When the driving motor 2 is started, the rotating body 3 rotates around the cylinder 12 through the transmission of the first belt pulley 21, the belt 22, and the second belt pulley.

[0040] In this embodiment, the bracket 1 includes several legs, and a U-shaped platform surface is provided on the legs. The two supports 11 are respectively arranged on the two branch surfaces of the platform surface, so that the rotating body 3 is in a hollow position, thereby providing sufficient space for the rotation of the rotating body 3; the second belt pulley is fixedly connected to the side of the rotating body 3, and when the second belt pulley is connected to the rotating body 3, it also takes the cylinder 12 as the axis. Therefore, the rotating body 3 driven by the second belt pulley also rotates with the cylinder 12 as the axis.

[0041] As Figures 1 - 5 shown, as a preferred embodiment, the air extraction pipe 4 extends into the cylinder 12 from the open end of the cylinder 12. A second through hole 123 is formed in the wall of the cylinder 12 in the cavity, thereby forming an air passage between the air extraction pipe 4 and the cavity, so that the gas in the cavity can enter the air extraction pipe 4 through the second through hole 123 and then be extracted by the air extractor.

[0042] In this embodiment, the second through hole 123 can be set to one or more, and the shape of the second through hole 123 can be a round hole or a square hole, which is not limited herein; when the air extractor starts to extract air, the air in the cavity enters the cylinder 12 through the second through hole 123, and then enters the air extraction pipe 4 through the cylinder 12, so that the air in the cavity is extracted to form a negative pressure.

[0043] As a preferred embodiment, a shielding member 124 is further provided on the wall of the cylinder 12 in the cavity. One end of the shielding member 124 is fixedly connected to the wall of the cylinder 12, and the other end is set to a shape adapted to the inner wall arc surface of the rotating body 3, for shielding the first through hole 31 on the rotating body 3. When the first through hole 31 rotates with the rotating body 3 to the position where the shielding member 124 is located, the shielding member 124 blocks the first through hole 31, so that the adsorption effect of the first through hole 31 on the paper cup stops, and the paper cup falls off from the rotating body 3.

[0044] In this embodiment, the shape of the end of the shielding member 124 that shields the first through hole 31 is also set to be arc-shaped, and the radian is consistent with the arc surface of the rotating body 3, so that while the shielding member 124 shields the first through hole 31, it will not obstruct the rotation of the rotating body 3; furthermore, the user can set the position of the shielding member 124 according to needs, so that the end of the shielding member 124 that shields the first through hole 31 faces a certain direction (such as horizontally downward). When the paper cup is rotated to the position pointed by this end, the first through hole that adsorbs the paper cup is blocked, and the paper cup falls off, that is, the paper cup can fall off at the position set by the user.

[0045] As Figure 6 shown in the second belt 22 wheel, an embodiment of the present invention also provides a paper cup detector, which includes:

[0046] A detector body 5;

[0047] A first conveying mechanism 51, arranged on the detector body 5, for feeding the paper cups;

[0048] A first vision mechanism 52, arranged on the detector body 5;

[0049] The described paper cup flipping device, arranged on the detector body 5. When the paper cup is conveyed to the paper cup flipping device by the first conveying mechanism 51, one end of the paper cup is adsorbed by the paper cup flipping device, and then the paper cup flipping device rotates the paper cup by a first angle so that the other end of the paper cup faces the first vision mechanism 52, so that the first vision mechanism 52 can collect an image of the end of the paper cup that is not adsorbed.

[0050] A second conveying mechanism 53, arranged on the detector body 5;

[0051] A second vision mechanism 54, arranged on the detector body 5. After the first vision mechanism 52 completes image acquisition, the paper cup flipping device further rotates by a second angle and then stops adsorbing the paper cup, and the paper cup falls off, and the end of the paper cup that is not adsorbed lands on the second conveying mechanism 53. Under the conveyance of the second conveying mechanism 53, the paper cup moves to a position facing the second vision mechanism 54, so that the second vision mechanism 54 can collect an image of the other end of the paper cup.

[0052] A blanking mechanism, arranged on the detector body 5, for blanking the detected paper cups.

[0053] In this embodiment, both the first vision mechanism 52 and the second vision mechanism 54 can be high-definition industrial cameras to collect high-definition images of the paper cups; the first conveying mechanism 51 is arranged above the rotating body 3 of the paper cup turning device, and the paper cups conveyed by it fall on the rotating body 3. The rotating body 3 rotates counterclockwise by 90 degrees (i.e., the first angle) so that the unadsorbed end of the paper cup faces the first vision mechanism 52 for visual inspection of this end. Subsequently, the rotating body 3 drives the paper cup to rotate counterclockwise by another 90 degrees (i.e., the second angle). The shielding member 124 in the rotating body 3 shields the first through hole 31 that adsorbs the paper cup, causing the paper cup to be turned over and fall on the second conveying mechanism 53 (which can be set as a negative pressure conveyor belt). The negative pressure conveyor belt moves the paper cup under the second vision mechanism 54 for visual inspection of the other end of the paper cup. Subsequently, the paper cup is further conveyed to the blanking mechanism through the second conveying mechanism 53 to blank the inspected paper cup.

[0054] In this embodiment, the turning process of the paper cup by the paper cup turning device is simple. After turning over the adsorbed paper cup, it can quickly adsorb a new paper cup for turning over, and can turn over multiple paper cups simultaneously. In addition, visual inspection of one end of the paper cup can be achieved during the turning process of the paper cup, greatly improving the efficiency of turning over and inspecting the paper cup, and thus improving the overall efficiency of paper cup inspection.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
