Description

Technical Field

[0001] The utility model relates to the technical field of labeling, in particular to a device for assisting in labeling steel drums. Background Art

[0002] In the prior art (taking the heavy barrel rotary labeling machine with the application number 201911227508.4 and the invention name as an example), when labeling a steel drum, the main method is random labeling. As long as the steel drum is moved into place, regardless of the orientation of the barrel opening at the top of the steel drum, the labeling process will be carried out randomly. This results in a large randomness in the relative position between the barrel opening and the label after the steel drum is labeled. If the direction of the label is guaranteed to be the same, then the direction of the barrel opening will be different. If the direction of the barrel opening is guaranteed to be the same, then the label does not know where it will face. This brings great trouble to the receiving party of the steel drum. Summary of the Utility Model

[0003] In order to solve the problems existing in the prior art, the utility model provides an auxiliary labeling device, which can identify the orientation of the barrel opening and adjust the direction of the barrel opening accordingly, so as to solve the problem that the directions of the barrel openings are different after labeling.

[0004] To achieve the above object, the following technical solutions are provided:

[0005] An auxiliary labeling device includes a support frame, a conveying roller path, a pair of centering devices, an image device, and a clamping and rotating device.

The centering rollers of the two centering devices are arranged oppositely and are both driven laterally.

[0009] The centering device is mounted on the side beam of the support frame, and the side beam is located at the lower part of the support frame.

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated herein can be arranged and designed in various different configurations.

[0030] Embodiment

[0031] Such as Figures 1-5As shown in the figure, the present utility model provides an auxiliary labeling device, which includes a support frame 10, a conveying roller path 20, a pair of centering devices 30, an image device 40, and a clamping and rotating device 50. Among them, the support frame 10 is a cuboid frame structure, the conveying roller path 20 is arranged inside the support frame 10, and the centering devices 30 are installed on both sides of the conveying roller path 20; at the top of the support frame 10, there are a first longitudinal beam 11 and a second longitudinal beam 12. The first longitudinal beam 11 is parallel to the second longitudinal beam 12, and the height of the first longitudinal beam 11 is higher than that of the second longitudinal beam 12. The image device 40 is fixedly installed on the first longitudinal beam 11 and is directly above the output end of the conveying roller path 20. The lens of the image device 40 is vertically downward; the clamping and rotating device 50 is movably installed on the second longitudinal beam 12 and can move along the second longitudinal beam 12 to directly below the image device 40. The image device 40 can be a 3D camera. In this embodiment, by moving the clamping and rotating device 50, the image device 40 can be avoided, so that after the steel barrel 60 moves into place, the image device 40 can be used to take a downward image of the steel barrel, thereby determining the position of the barrel opening on the steel barrel.

[0032] The auxiliary labeling device provided by the present utility model can detect and confirm the in-place situation of the steel barrel on the conveying roller path 20. The centering device 30 centers and positions the steel barrel directly below the image device 40, and the image device 40 identifies the barrel opening on the steel barrel downward. Then, the clamping and rotating device 50 can be used to lift and rotate the steel barrel to adjust the barrel opening to a predetermined orientation. Thus, after labeling the side of the steel barrel, the label and the direction of the barrel opening of the steel barrel are both neat and uniform, and the labeling effect is better.

[0033] The clamping and rotating device 50 includes: a linear guide rail 51, a driving moving cylinder 52, a moving frame 53, a lifting cylinder 54, and a clamping jaw 55. Among them, the linear guide rail 51 is arranged along the second longitudinal beam 12, the moving frame 53 is slidably installed on the linear guide rail 51, one end of the driving moving cylinder 52 is installed on the second longitudinal beam 12, and the other end is connected to the moving frame 53; the lifting cylinder 54 is installed on the moving frame 53, and the bottom of the lifting cylinder 54 is connected to the clamping jaw 55. The clamping and rotating device 50 also plays an important role in the auxiliary labeling device provided in this embodiment. The lifting cylinder 54 of the clamping and rotating device 50 can lift the steel barrel, so as to facilitate the rotation adjustment of the steel barrel 60 and make the barrel opening on the steel barrel 60 point to a predetermined orientation; the driving moving cylinder 52 therein can drive the entire moving frame 53 to move along the linear guide rail 51, so as to avoid when the image device takes an image, and can reset and clamp the steel barrel after the image is taken.

[0034] The gripper 55 is provided with a rotation driving mechanism for driving the gripper 55 to rotate. The rotation driving mechanism can be a gear drive, a belt pulley drive, or a rotary cylinder drive. Any rotation driving method commonly used by those skilled in the art is acceptable.

[0035] Each centering device 30 includes two centering rollers 31, a driving block 32, and a driving centering cylinder 33. The centering rollers 31 are installed on the driving block 32, and the driving centering cylinder 33 is used to drive the driving block 32. The height of the centering rollers 31 is higher than that of the conveying roller path 20 and is closer to the conveying roller path 20 than the gripper 55. The centering rollers 31 of the two centering devices 30 are arranged oppositely and are both driven laterally. The synchronous centering action of the two centering devices 30 can move the steel drum 60 directly below the imaging device 40, facilitating clamping and rotation. The centering rollers 31 can rotate to provide rotational support for the surface of the steel drum during the rotation after the lifting and rotation of the steel drum by the clamping and rotating device 50. Of course, during the clamping and lifting of the steel drum by the clamping and rotating device 50, the centering device needs to be released; it is clamped again during rotation to provide rotational support and avoid shaking during the rotation of the steel drum. After the rotation is completed, the centering device is released again to allow the steel drum to fall back to its original position.

[0036] The centering device 30 is installed on the side beam 13 of the support frame 10, and the side beam 13 is located at the lower part of the support frame 10.

[0037] The conveying roller path 20 is supported and connected to the bottom beam 14 of the support frame 10. The bottom beam 14 is located at the bottom of the support frame 10, and the conveying roller path 20 is connected to the bottom beam 14 through a height adjustment mechanism.

[0038] The height adjustment mechanism is a support screw or a lifting drive cylinder.

[0039] Above the output end of the conveying roller path 20, a horizontally arranged first grating scale 21 is further provided. The first grating scale 21 is obliquely arranged between the centering devices 30 to detect the steel barrels that move to the output end along the conveying roller path 20. The function of designing the first grating scale 21 is to cooperate with the centering device. Since the usual grating scales are arranged horizontally (instead of obliquely), but due to the existence of the centering device 30, if it is arranged horizontally at the downstream position of the centering device, when the grating scale detects the steel barrel, the steel barrel has already passed the centering device 30, and the centering adjustment of the steel barrel cannot be achieved. Therefore, by adopting the oblique arrangement method, the position of the steel barrel between the centering devices 30 can be detected; and such a design also fully considers the working space of the labeling mechanism. The labeling mechanism is usually located on the side of the steel barrel, and the centering device 30 is also located at the lower part of the side of the steel barrel. Therefore, in order to avoid interference with the labeling mechanism, the first grating scale 21 is designed to be obliquely arranged with the centering device, so that they can be kept at almost the same height, which also reserves sufficient working space for the labeling mechanism.

[0040] The direction of the first grating scale 21 forms a 45-degree angle with the centering direction of the two centering devices 30.

[0041] Above the input end of the conveying roller path 20, a horizontally arranged second grating scale 22 is further provided. The second grating scale 22 is arranged transversely with respect to the conveying roller path 20 to detect the steel barrels entering the conveying roller path 20. The function of the second grating scale 22 is that after the steel barrel is transported onto the conveying roller path 20, corresponding signals can be detected through the second grating scale 22, thus avoiding misoperation.

[0042] Note that the above is only the preferred embodiment of the present invention and the applied technical principles. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described here. Various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Without departing from the concept of the present invention, more other equivalent embodiments can be included, and the scope of the present invention is determined by the scope of the appended claims.
