Description

Technical Field

[0001] The invention relates to the technical field of filling detection, and in particular to a classification device and a container bottle detection system. Background Art

[0002] Automotive urea refers to a urea aqueous solution with a urea concentration of 32.5% and ultrapure water as the solvent. The automotive urea on the market is generally used with a filling machine or stored in a container bottle. The bottling of automotive urea is usually completed by a filling machine, and then the capping machine seals it and sends it to the labeling machine for labeling. After the label is affixed, it is sent to the cartoning machine for packaging.

[0003] In order to ensure the production quality, each process is equipped with a corresponding detection unit. For example, the patent with publication number CN114772007B discloses a round bottle labeling detection device and a round bottle labeling detection method, which can be used to detect the labels attached to round bottles. Generally, each test result is divided into two different situations: qualified or unqualified. After the test, the products with different test results need to be classified and stored. After the existing classification device classifies each product, its classification actuator needs to be reset to the initial position, and the classification work is in a stopped state during the reset. However, when this classification device is used for batch product classification, due to the large number of products, the classification device needs to be reset after each product is classified, resulting in a long total reset time, which will extend the production cycle. Summary of the invention

[0004] Based on the above-mentioned problems existing in the prior art, the present invention aims to solve the technical problem that the classification actuator of the classification device in the prior art needs to be reset to the initial position after classifying each product, resulting in a long total reset time and prolonging the production cycle.

[0005] The present invention provides a classification device, which includes a plurality of material moving mechanisms, wherein the material moving mechanisms include a main turntable, a plurality of material moving rods and a driving assembly, wherein the main turntables of the plurality of material moving mechanisms are coaxially arranged, and the plurality of material moving rods are evenly distributed on the corresponding main turntable along the circumferential direction, and the outer area of ​​the corresponding main turntable is divided into a plurality of sub-areas, and the material moving rods are configured to be rigid when they are subjected to a positive force and flexible when they are subjected to a reverse force, wherein the positive direction is the opposite direction of the rotation direction of the main turntable; the driving assembly is used to drive the corresponding main turntable to rotate intermittently, and the angle of each rotation is the arc corresponding to a sub-area;

[0006] When the main turntable stops, one of the sub-areas is defined as a feed buffer area, and multiple material transfer mechanisms share one feed buffer area, and according to the rotation direction of the main turntable, a sub-area adjacent to the sub-area is used as a material storage area; the number of material transfer rods of multiple material transfer mechanisms is different, so that the positions of the material storage areas of multiple material transfer mechanisms are different.

[0007] According to an embodiment of the present invention, the material moving rod comprises:

[0008] A plurality of connecting rods articulated in sequence;

[0009] A mounting block, fixedly disposed on the main turntable, one end of one of the connecting rods located at the end is hinged to the mounting block;

[0010] Torsion springs are provided at the hinges between the connecting rods and the connecting rods with the mounting block, and the torsion springs can support the connecting rods to return to their initial state after flipping;

[0011] A plurality of stop blocks and a plurality of limiting protrusions, the stop blocks and the limiting protrusions are respectively fixedly arranged on two adjacent connecting rods, wherein the stop block is fixedly arranged on a connecting rod closer to the main turntable, and the limiting protrusion is fixedly arranged on a connecting rod farther from the main turntable and is located at an end of the connecting rod close to the main turntable, when the material tapping rod is unfolded and straightened, the stop block and the corresponding limiting protrusion fit each other, and the stop block and the corresponding limiting protrusion are distributed along the rotation direction of the main turntable; the mounting block and the end of a connecting rod close to the mounting block are respectively fixedly arranged with the stop block and the limiting protrusion.

[0012] According to an embodiment of the present invention, the material shifting rods of the plurality of material shifting mechanisms are arranged in parallel at the position of the material feed buffer area, so that the material feed buffer area has the largest area.

[0013] According to an embodiment of the present invention, there are two material transfer mechanisms, and the main turntables of the two material transfer mechanisms are arranged opposite to each other from top to bottom.

[0014] According to one embodiment of the present invention, the classification device also includes a machine platform and a frame fixedly arranged on the top of the machine platform, the driving component of the main turntable located below is arranged in the machine platform, and the driving component of the main turntable located above is arranged on the frame.

[0015] According to an embodiment of the present invention, the classification device further includes an annular enclosure arranged around the outer side of the main turntable.

[0016] The present invention also provides a container bottle detection system, which comprises:

[0017] The classification device, and

[0018] The visual inspection device is used to inspect the container bottles located in the feed buffer area based on image detection technology. After the multiple material transfer mechanisms move the container bottles located in the feed buffer area to different storage areas based on the detection results, the container bottles are unloaded by an external unloading device.

[0020] The classification device and container bottle detection system provided by the present invention have the following beneficial effects:

[0021] (1) Since the storage areas corresponding to the plurality of material transfer mechanisms are different, the plurality of material transfer mechanisms are operated separately, that is, the container bottles can be transferred to different storage areas respectively, thereby realizing classified storage of the container bottles; in addition, each time the driving component in the material transfer mechanism drives the main turntable to rotate intermittently once, the material transfer rod can transfer the container bottles located in the feed buffer area to the storage area, and since the angle of each intermittent rotation of the main turntable is an arc corresponding to one of the sub-areas, when the material transfer rod moves to the storage area, the next material transfer rod can move to the feed buffer area without performing an additional resetting action on the material transfer rod, thereby saving resetting time;

[0022] (2) Since the material shifting rod is configured to be rigid when subjected to positive force and flexible when subjected to negative force, wherein the positive direction is opposite to the rotation direction of the main turntable, when the material shifting mechanism is working, the corresponding material shifting rod is subjected to the positive thrust of the container bottle and becomes rigid, thereby being able to transfer the container bottle normally; while when the remaining material shifting mechanisms are working, the material shifting rod of the non-working material shifting mechanism is subjected to the negative thrust of the moving container bottle and becomes flexible, thereby not affecting the normal operation of the remaining material shifting mechanisms.

[0027] The following descriptions of the embodiments refer to the attached drawings to illustrate specific embodiments in which the present invention can be implemented.

[0028] The present invention provides a classification device, the structure of which is as follows Figure 1 and Figure 2 As shown, it includes a plurality of material moving mechanisms 1, and the material moving mechanisms 1 include a main turntable 11, a plurality of material moving rods 12 and a driving assembly 13. The main turntables 11 of the plurality of material moving mechanisms 1 are coaxially arranged, and the plurality of material moving rods 12 are evenly distributed on the corresponding main turntables 11 along the circumferential direction, and the outer area of ​​the corresponding main turntable 11 is divided into a plurality of sub-areas, and the material moving rods 12 are configured to be rigid when subjected to a positive force and flexible when subjected to a reverse force, wherein the positive direction is the opposite direction of the rotation direction of the turntable 11; The driving assembly 13 is used to drive the corresponding main turntable 11 to rotate intermittently, and the angle of each rotation is the arc corresponding to a sub-area; when the main turntable 11 stops, one of the sub-areas is defined as a feed buffer area, and multiple material transfer mechanisms 1 share one feed buffer area, and according to the rotation direction of the main turntable 11, a sub-area adjacent to the sub-area is used as a material storage area, and the number of the material transfer rods 12 of the multiple material transfer mechanisms 1 is different, so that the positions of the material storage areas of the multiple material transfer mechanisms 1 are different.

[0029] In a classification device provided by the present invention, since the storage areas corresponding to the multiple material transfer mechanisms 1 are different, the multiple material transfer mechanisms 1 are operated separately, that is, the container bottles can be transferred to different storage areas respectively, thereby realizing the classified storage of container bottles; in addition, each time the driving component 13 in the material transfer mechanism 1 drives the main turntable 11 to rotate intermittently once, the material transfer rod 12 can transfer the container bottles located in the feed buffer area to the storage area, and since the angle of each intermittent rotation of the main turntable 11 is the arc corresponding to one of the sub-areas, when the material transfer rod 12 moves to the storage area, the next material transfer rod 12 can move to the feed buffer area, and There is no need to perform additional resetting action on the material shifting rod 12, thus saving resetting time; at the same time, since the material shifting rod 12 is configured to be rigid when it is subjected to positive force and to be flexible when it is subjected to reverse force, wherein the positive direction is opposite to the rotation direction of the main turntable 11, when the material shifting mechanism 1 is working, the corresponding material shifting rod 12 is subjected to the positive thrust of the container bottle 100 and becomes rigid, thereby being able to transfer the container bottle 100 normally, and when the rest of the material shifting mechanisms 1 are working, the material shifting rod 12 of the non-working material shifting mechanism 1 is subjected to the reverse thrust of the moving container bottle 100 and becomes flexible, thereby not affecting the normal operation of the rest of the material shifting mechanisms 1.

[0030] Specifically, in order to realize "the material-moving rod 12 is configured to be rigid when it is subjected to a positive force and to be flexible when it is subjected to a reverse force, wherein the positive direction is the reverse direction of the rotation direction of the main turntable 11", as Figure 3 Shown Figure 1In the enlarged schematic diagram of part A in the middle, the material removing rod 12 includes a plurality of connecting rods 121, a mounting block 122, a torsion spring 123, a plurality of stop blocks 124 and a plurality of limiting protrusions 125 which are hinged in sequence, wherein the mounting block 122 is fixedly arranged on the main turntable 11, and one end of one of the connecting rods 121 located at the end is hinged to the mounting block 122, and the hinge axis is parallel to the central axis of the main turntable 11; the torsion spring 123 is arranged at the hinges between the connecting rods 121 and the hinges with the mounting block 122, and the torsion spring 123 can support the connecting rod 121 to return to the initial state after flipping; the stop block 124 and the limiting protrusion 125 are fixedly arranged on two adjacent connecting rods 121, respectively, wherein the stop block 124 is fixedly arranged on the connecting rod 121 which is closer to the main turntable 11 On the rod 121, the limiting protrusion 125 is fixedly set on the connecting rod 121 which is farther away from the main turntable 121, and is located at an end of the connecting rod 121 close to the main turntable 11. When the material tapping rod is unfolded and straightened, the stop block 124 and the corresponding limiting protrusion 125 fit each other, and the stop block 124 and the corresponding limiting protrusion 125 are distributed along the rotation direction of the main turntable 11. Specifically, since the rotation direction of the main turntable 11 is the tangential direction of the main turntable 11, the stop block 124 and the corresponding limiting protrusion 125 are distributed left and right on the material tapping rod 12 along the width direction of the material tapping rod 12; the mounting block 122 and the end of the connecting rod 121 close to the mounting block 122 are respectively fixedly provided with the stop block 124 and the limiting protrusion 125.

[0031] It can be understood that the stop block 124 cooperates with the limiting protrusion 125 to limit the connecting rod 121 to be able to flip relative to the mounting block 122 only in the direction of rotation of the main turntable 11, and limit the one of the two adjacent connecting rods 121 that is farther from the main turntable 11 to be able to flip relative to the other in the direction of rotation of the main turntable 11. Therefore, when the material shifting mechanism 1 is working, that is, when the main turntable 11 drives the corresponding material shifting rod 12 to rotate, the material shifting rod 12 is affected by the rotation of the main turntable 11. The thrust to the container bottle 100 is in the opposite direction of the rotation of the main turntable 11. At this time, the material-moving rod 12 is rigid, so that the material can be pushed normally; when the material-moving mechanism 1 is not working, and another material-moving mechanism 1 is working, the non-working material-moving rod 12 is pushed by the container bottle 100 along the rotation direction of the main turntable 11 (the rotation direction of the main turntable 11 in all material-moving mechanisms 1 is the same). At this time, the non-working material-moving rod 12 is flexible, so as not to affect the operation of other material-moving mechanisms 1. It should be noted that in order to enable the non-working material-moving rod 12 to be fully bent and folded, the greater the overall flexibility of the material-moving rod 12, the better. However, due to the structural limitations of the material-moving rod 12 (the main structure of the material-moving rod 12 is a plurality of connecting rods 121 hinged in sequence, and the connecting rods 121 are rigid), the "flexibility" referred to in this scheme is actually "local flexibility".

[0032] Please continue to refer to Figure 1 Generally, the feed buffer area is usually connected to an external feed device (such as a feed conveyor line). In order to ensure that the feed buffer area has a sufficient area to facilitate the transfer of the container bottle 100 from the external feed device to the feed buffer area, the multiple material transfer mechanisms 1 have parallel material rods 12 at the position of the feed buffer area so that the feed buffer area has the largest area.

[0033] As a specific embodiment, there are two material transfer mechanisms 1 , and the main turntables 11 of the two material transfer mechanisms 1 are arranged opposite to each other from top to bottom.

[0034] Furthermore, the classification device also includes a machine table 2 and a frame 3 fixedly arranged on the top of the machine table 2, the driving component 13 of the main turntable 11 located below is arranged in the machine table 2, and the driving component 13 of the main turntable 11 located above is arranged on the frame 3.

[0035] According to one embodiment of the present invention, in order to prevent the container bottle 100 from escaping from the pushing range of the material transferring device 1 when the material transferring device 1 transfers the container bottle 100, the classification device also includes an annular enclosure 4 arranged on the outside of the main turntable 11, which can limit the container bottle 100 within a certain area; preferably, the distance between the inner wall of the annular enclosure 4 and the outer circumferential surface of the main turntable 11 is greater than the diameter of the container bottle 100, and the length of the material transferring rod 12 should be greater than the radius of the container bottle 100, so that the material transferring rod 12 can always transfer the container bottle located in the annular enclosure 4.

[0036] The present invention also provides a container bottle detection system, which includes the classification device and a visual detection device 200. The visual detection device 200 is used to detect the container bottles 100 located in the feed buffer area based on image detection technology. After the multiple material transfer mechanisms 1 move the container bottles 100 located in the feed buffer area to different storage areas based on the detection results, the container bottles 100 are unloaded by an external unloading device. Specifically, the external unloading device can be a robot with a manipulator.

[0037] According to one embodiment of the present invention, the container bottle detection system also includes a secondary turntable 300 rotatably arranged in the feed buffer area, which is used to drive the container bottle 100 to be inspected to rotate; the visual inspection device 200 collects and inspects the label attached to the surface of the container bottle 100 during the rotation of the container bottle 100.

[0038] In order to facilitate the understanding of this scheme, the following Figure 1-Figure 3 The working principle of the present invention is described in detail:

[0039] During operation, the container bottle 100 to be inspected is transferred to the auxiliary turntable 300 of the feed buffer area through an external feeding device. Specifically, the external feeding device can be an intermittently started feeding conveyor line. The auxiliary turntable 300 is started to drive the container bottle 100 to be inspected to rotate at least one time. During the rotation of the container bottle 100, the visual inspection device 200 collects and inspects the label attached to the surface of the container bottle 100. The inspection results are qualified and unqualified.

[0040] In this embodiment, the material transfer mechanism 1 located at the bottom is used to transfer qualified container bottles 100, and the material transfer mechanism 1 located at the top is used to transfer unqualified container bottles 100 (in actual use, the user can decide which of the two material transfer mechanisms 1 is used to transfer qualified products or unqualified products according to actual needs, and there is no special limitation in this embodiment). Among them, the number of the material transfer rods 12 in the material transfer mechanism 1 located at the bottom is 4, the number of sub-areas is 4, and the arc corresponding to each sub-area is 90°; the number of the material transfer rods 12 in the material transfer mechanism 1 located at the top is 3, the number of sub-areas is 3, and the arc corresponding to each sub-area is 120°.

[0041] When the inspection result of the visual inspection device 200 is qualified, the driving component 13 of the lower material transfer mechanism 1 starts and drives the corresponding main turntable 11 to rotate counterclockwise by 90°, so as to push the qualified container bottle 100 to the corresponding storage area of ​​the lower material transfer mechanism 1, and its corresponding external unloading device unloads the container bottle 100 from the storage area; when the visual inspection result is unqualified, the driving component 13 of the upper material transfer mechanism 1 starts and drives the corresponding main turntable 11 to rotate counterclockwise by 120°, so as to push the unqualified container bottle 100 to the corresponding storage area of ​​the upper material transfer mechanism 1, and its corresponding external unloading device unloads the container bottle 100 from the storage area.

[0042] It should be noted that in order to prevent the container bottles 100 in the material storage area from interfering with the movement of the material removal rod 12 of the main turntable 11 that is rotating again, once there are container bottles 100 in the material storage area, the external unloading device will start to unload the container bottles 100 in the material storage area.

[0043] When the container bottles 100 on the secondary turntable 300 are transferred to any of the storage areas, the external feeding device is started again to transfer the next container bottle 100 to be inspected to the secondary turntable 300. The above process is repeated to achieve batch inspection of container bottles 100 and classification of container bottles 100 with different inspection results (qualified or unqualified).

[0044] In summary, the classification device and container bottle detection system provided by the present invention can classify container bottles according to the detection results, and the material transfer rod 12 does not need to be reset additionally after each classification, which saves the reset time and is suitable for the detection and classification of large quantities of container bottles 100.

[0045] It should be noted that although the present invention is disclosed as above by specific embodiments, the above embodiments are not intended to limit the present invention. Ordinary technicians in this field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
