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] Taking the patent application No. 201911227508.4 with the invention name of "Heavy Drum Rotary Labeling Machine" as an example, when clamping and labeling a steel drum, two parallel racks (the first rack 54 and the second rack 53) are used to drive two jaws (the first jaw 57 and the second jaw 56) respectively to achieve the clamping action. When using the rack structure for driving, complex structures such as guide rails also need to be designed to cooperate with the action of the rack structure, which inevitably leads to an overly complex structure of the mechanism for clamping the steel drum. At the same time, the patent document adopts a two-point clamping method, and the steel drum cannot maintain good stability after being clamped.

[0003] In addition, in the prior art, during the labeling process, the identification and positioning of the barrel mouth cannot be achieved, which also makes the labeling very random. The directions of the labels and the barrel mouths of the labeled steel drums are different, which also brings difficulties to the work of the receiving party. Summary of the Utility Model

[0004] In order to solve the problems existing in the prior art, the utility model provides an auxiliary labeling device, which clamps the steel drum by means of synchronous driving of three jaws, with a simple and more stable structure, and solves the problem of unstable clamping of the existing steel drum.

[0005] To achieve the above object, the following technical solutions are provided:

[0006] An auxiliary labeling device includes a support frame, a conveying roller path, an image device, and jaws. The conveying roller path is located at the bottom inside the support frame, and the image device and the jaws are located at the top of the support frame. The height of the jaws is lower than that of the image device, and the jaws can be moved directly below the image device. The jaws are driven by a driving cylinder to rotate a driving plate through the axis, and the driving plate drives the clamping blocks on three linear guide rails through three driving rods.

[0007] The jaws include: a top plate, a driving plate, linear guide rails, driving rods, a driving cylinder, and clamping blocks. A rotatable driving plate is installed at the center of the top plate. Three linear guide rails with an included angle of 120 degrees to each other are arranged at the lower part of the top plate, and the three linear guide rails are arranged radially around the circumference of the driving plate. A clamping block is slidably installed on each linear guide rail, and the driving plate drives the clamping blocks through three driving rods in the circumferential direction. And the driving plate is driven to rotate by the driving cylinder at the lower part of the top plate.

[0008] The driving cylinder is connected to the driving plate, the driving cylinder is connected to the top plate, the driving rod is connected to the driving plate, and the driving rod is connected to the clamping block by means of hinge connections.

[0009] The bottom of the clamping block is lower than the heights of the driving plate, the linear guide rail, the driving rod, and the driving cylinder.

[0010] The clamping jaw further includes an anti-collision pad, which is installed at the lower part of the driving plate, and the height of the anti-collision pad is higher than the height of the clamping block.

[0011] The clamping block is L-shaped, and the inner side of the clamping block is made of hard rubber or hard plastic.

[0012] A longitudinal beam is provided at the top of the support frame, and the top of the clamping jaw is connected to the slide rail on the longitudinal beam through a moving seat.

[0016] Compared with the prior art, the advantages of the present utility model are as follows:

[0017] The auxiliary labeling device provided by the present utility model is such that one driving cylinder drives three driving rods through a driving plate to control the simultaneous actions of three clamping blocks. Compared with the prior art that uses a rack structure and a clamping jaw structure arranged oppositely, it can achieve three-point positioning clamping, so that the clamping effect is better, and the structure is also more simple and practical; further with the aid of an image device and a centering adjustment mechanism, the steel drum can be rotated and adjusted before labeling, so that the barrel opening on the steel drum is located in a preset orientation.

[0030] 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 in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, 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 in the accompanying drawings here can be arranged and designed in various different configurations.

[0031] Embodiment

[0032] As Figures 1-6 shown, the present utility model provides an auxiliary labeling device, including a support frame 10, a conveyor roller path 20, an image device 30, and a jaw 40. The conveyor roller path 20 is located at the bottom inside the support frame 10, and the image device 30 and the jaw 40 are located at the top of the support frame 10. Among them, the height of the jaw 40 is lower than the height of the image device 30, and the jaw 40 can move to directly below the image device 30; the jaw 40 is rotated by a driving cylinder 45 through a driving plate 42 at the axis, and the driving plate 42 drives the clamping blocks 46 on three linear guide rails 43 through three driving rods 44.

[0033] The support frame 10 provides frame support for the entire auxiliary labeling device and provides installation space for the conveyor roller 20; the conveyor roller 20 can convey the steel drum to the bottom of the image device 30 so that it can be identified by the image device 30; the clamp 40 can complete the clamping, lifting and rotating operations of the steel drum, thereby cooperating with the labeling machine to complete labeling. The image device 30 can use a 3D camera, the clamp 40 adopts a three-claw structure layout, and a driving cylinder drives the driving rod 44 through the driving plate 42 to control the clamp block 46 on the linear guide 43 to reciprocate, thereby achieving the clamping or release of the steel drum.

[0034] During implementation, the auxiliary labeling device provided in this embodiment also needs to be used in conjunction with a conventional labeling machine (not shown in the figure), which is placed on the side of the auxiliary labeling device so that it can rotate and label the steel drum.

[0035] The auxiliary labeling device provided by the utility model is driven by a driving cylinder 45 through a driving plate 42 to drive three driving rods 44 to control three clamping blocks 46 to move simultaneously. Compared with the prior art that adopts a rack structure and relatively arranged clamping claws 40, it can achieve three-point positioning clamping, so that the clamping effect is better, and the structure is simpler and more practical; further, with the help of the image device 30 and the centering adjustment mechanism, the steel drum can be rotated and adjusted before labeling, so that the barrel mouth on the steel drum is located at a preset orientation. After the labeling is completed, the orientation of the label and the barrel mouth can be kept consistent.

[0036] The clamping jaw 40 includes: a top plate 41, a driving plate 42, a linear guide 43, a driving rod 44, a driving cylinder 45 and a clamping block 46. A rotatable driving plate 42 is installed at the center of the top plate 41. The lower part of the top plate 41 is provided with three linear guides 43 with an angle of 120 degrees to each other. The three linear guides 43 are radially arranged around the circumference of the driving plate 42; a clamping block 46 is slidably installed on each linear guide 43, and the clamping block 46 is driven by three driving rods 44 in the circumference of the driving plate 42; and the driving plate 42 is driven to rotate by the driving cylinder 45 at the lower part of the top plate 41. The top plate 41 can be circular or triangular (to adapt to the three-claw structure). The top plate 41 serves as the basis for the clamping of the entire clamp 40 and is the carrier of other related structural components. The linear guide 43 is directly fixed on the lower part of the top plate 41. The linear guide 43 can adopt a grooved guide so that it can withstand the downward pulling force of the clamp 46. The driving plate 42 adopts an annular structure. The center of the driving plate 42 is also the rotation center of the entire top plate 41. The two can be connected by a rotating shaft. The hinge points on the circumference of the driving plate 42 can be designed respectively for the driving rod 44 and the driving cylinder 45, so that the driving plate 42 can be driven by the driving cylinder 45, and the driving plate 42 drives the driving rod 44 to drive the acceleration 46.

[0037] The driving cylinder 45 is connected to the driving plate 42, the driving cylinder 45 is connected to the top plate 41, the driving rod 44 is connected to the driving plate 42, and the driving rod 44 is connected to the clamping block 46 by means of hinge connections. Correspondingly, hinge structures (such as hinge holes, hinge seats, etc.) also need to be designed between the clamping block 46, as well as between the top plate 41 and the driving cylinder 45 for connection.

[0038] The bottom of the clamping block 46 is lower than the heights of the driving plate 42, the linear guide rail 43, the driving rod 44, and the driving cylinder 45. The main function of the clamping block 46 is to clamp the steel drum, so the height of the lowest point of the clamping block 46 needs to be designed to be lower than the heights of other related structures to avoid interference from other structures to the clamping block 46.

[0039] The clamping jaw 40 further includes an anti-collision pad 47, which is installed at the lower part of the driving plate 42, and the height of the anti-collision pad 47 is higher than the height of the clamping block 46. The anti-collision pad 47 can prevent the clamping jaw 40 from directly colliding with the top surface of the steel drum during the downward movement. The anti-collision pad 47 buffers the impact force during the collision, thereby protecting the clamping jaw and the steel drum.

[0040] The clamping block 46 is L-shaped, and the inner side of the clamping block 46 is made of hard rubber or hard plastic.

[0041] A longitudinal beam 11 is provided at the top of the support frame 10, and the top of the clamping jaw 40 is connected to the slide rail on the longitudinal beam 11 through a moving seat 48. The longitudinal beam 11 serves as a support carrier for the movement of the clamping jaw 40. Through the slide rail designed on the longitudinal beam, the clamping jaw 40 can move along the slide rail. In this embodiment, the movement of the clamping block along the slide rail can be controlled by means of a cylinder drive, and one end of the cylinder can be fixedly connected to the longitudinal beam 11.

[0042] An elevating cylinder 49 is further provided on the moving seat 48, which is used to control the lifting movement of the clamping jaw 40. A rotating cylinder 50 is also provided at the bottom of the elevating cylinder 49, and the rotating cylinder 50 is connected to the top plate 41 to drive the clamping jaw 40 to rotate. The combined structural design of the elevating cylinder 49 and the rotating cylinder 50 can control the lifting and rotation of the clamping jaw, so as to cooperate with the labeling machine to complete the labeling action.

[0043] Centering adjustment mechanisms 21 are further provided on both sides of the conveying roller path 20. The centering adjustment mechanisms 21 drive the adjustment rollers 22 towards the center line direction of the conveying roller path 20 through cylinders to position the steel drum on the center line of the conveying roller path 20. The centering adjustment mechanisms 21 are arranged in pairs, pushing the steel drum 60 from both sides of the conveying roller path 20 towards the center. Two driving rollers 22 are further provided at the front end of each centering adjustment mechanism 21, and the two driving rollers can abut against the surface of the steel drum 60 and provide rotational support for the steel drum during the rotation of the steel drum.

[0044] A grating sensor 23 is also provided on the side of the conveying roller path 20 to detect the steel drum on the conveying roller path 20. The grating sensor 23 can detect the steel drum, thereby preparing for identifying the steel drum, centering and adjusting the steel drum, lifting the steel drum, and rotating the steel drum to complete the labeling operation.
