The label feeding assembly and adsorption assembly are mounted on the frame, and the material feeding assembly is positioned below the adsorption assembly. The label feeding assembly includes an unwinding section, a traction roller group, a detection section, a peeling plate, and a winding section, arranged sequentially along the label conveying direction. The adsorption assembly is a movable component that moves on a slide rail via a driving device, and the peeling plate is also a movable component that moves on a slide rail via a driving device. The label feeding assembly transports the label to the peeling plate, and the traction roller group guides the label roll to remain horizontal on the peeling plate. Under the action of the driving device, the adsorption assembly presses down onto the peeling plate, adsorbing the label onto the bottom surface of its working end.

Furthermore, air holes and air chambers are set at the working end to improve the smoothness and reliability of the pasting.

Description

Technical Field

[0001] This invention relates to the field of labeling, and more specifically, to a fully automatic labeling mechanism. Background Technology

[0002] In actual production, affixing labels to products is a necessary step before they leave the factory. The traditional method of labeling is manual, which is labor-intensive and time-consuming in actual production. Nowadays, some semi-automatic or automatic labeling devices have emerged to replace manual labeling. However, the labeling devices commonly found on the market do not perform well when peeling and pasting labels, and are prone to label wrinkles or even damage. They also cannot guarantee a smooth and firm label after application when dealing with labels of different materials and hardness. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a fully automatic labeling mechanism to overcome the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0005] A fully automatic labeling structure includes a frame, a label feeding assembly, an adsorption assembly, and a material feeding assembly. The label feeding assembly and adsorption assembly are mounted on the frame, and the material feeding assembly is positioned below the adsorption assembly. The label feeding assembly comprises an unwinding section, a traction roller group, a detection section, a peeling plate, and a winding section, sequentially distributed along the label conveying direction. The adsorption assembly is a movable component that moves on a slide rail via a driving device, and the peeling plate is also a movable component that moves on a slide rail via a driving device. The label feeding assembly transports the label to the peeling plate, and the traction roller group guides the label roll to remain horizontal on the peeling plate. Under the action of the driving device, the adsorption assembly presses down onto the peeling plate, adsorbing the label onto the bottom surface of its working end. After adsorbing the label, the adsorption assembly rises under the action of the driving device. At this time, the peeling plate retracts under the action of the driving device, exposing the material transported by the material feeding assembly below. The adsorption assembly then presses down to adhere the label to the material.

[0006] The adsorption assembly is equipped with a working end and a first adsorption slide rail. The working end can move in the Z-axis direction on the first adsorption slide rail by the action of the driving device. The working end includes a first adsorption substrate, a second adsorption substrate and a third adsorption substrate. A suction cup is installed on the bottom surface of the third adsorption substrate. When the adsorption assembly is pressed down to the label peeling plate, the working end adsorbs the label in a horizontal state. When the adsorption assembly is pressed down to the material, the working end releases the label and sticks it to the material while maintaining a horizontal state.

[0007] The adsorption assembly includes a working end, a first adsorption slide rail, and a second adsorption slide rail. The working end can move along the Z-axis of the first adsorption slide rail and along the X-axis of the second adsorption slide rail by a driving device. The working end includes a first adsorption substrate, a second adsorption substrate, and a third adsorption substrate. A connecting rod is provided on the working end a side of the first adsorption substrate, and the connecting rod has an elongated movable hole for the lifting part to connect and move. The first adsorption substrate is hinged to a hinge seat below the second adsorption slide rail on the working end b side, so that the working end can be lifted on the working end a side by the lifting part with the hinge seat as the axis under the action of the driving device. A roller is installed on the working end b side, and a suction cup is installed below the third adsorption substrate and extends outward from the working end b side. The extension position is below the roller. When the working surface adsorption assembly is pressed down onto the label peeling plate, the working end is in a horizontal state and the label is adsorbed by the suction cup under the action of the driving device. When the adsorption assembly is pressed down onto the material, the lifting part rises under the control of the driving device. The lifting part is displaced in the elongated movable hole to lift the working end a side. The roller is pressed down onto the material surface. At this time, the working end moves horizontally along the X-axis under the action of the driving device, driving the roller to roll from one end of the label to the opposite end, and sticking the label onto the material.

[0008] The second adsorption substrate is provided with an air channel, which is connected to the driving device. The third adsorption substrate is provided with regularly arranged air holes. The bottom surface of the second adsorption substrate is provided with a groove, and the top surface of the third adsorption substrate is provided with a groove. When the second and third adsorption substrates are installed, the grooves combine to form an air cavity. The air channel, the cavity, and the air holes are connected to form an adsorption path. When the driving device drives the working end to adsorb and release the label, it acts on the suction cup through the adsorption path.

[0009] Under the action of the drive device, the label peeling plate reciprocates along the Y-axis via the label peeling slide rail. It extends along the Y-axis when the adsorption component adsorbs the label and retracts along the X-axis when the adsorption component applies the label.

[0010] The label delivery assembly is equipped with a detection unit to check whether the label roll has a label during transport.

[0011] The traction roller assembly consists of a traction element and multiple traction rollers.

[0012] The above technical solution has the following beneficial effects:

[0013] The fully automatic labeling mechanism of this invention, through the design of two different adsorption components, can better peel off and stick labels when dealing with labels of different materials and hardness, thereby improving the smoothness and reliability of the adhesive application.

[0026] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] See Figures 1-8 As shown, the present invention discloses a fully automatic labeling mechanism, including: a frame 1 and a label feeding assembly 2 and an adsorption assembly 3 mounted on the frame 1. A feeding assembly 4 is provided below the adsorption assembly 3. The label feeding assembly 2 consists of an unwinding section 21, a first traction roller 221, a traction member 226, a second traction roller 222, a third traction roller 223, a fourth traction roller 224, a fifth traction roller 225, and a winding section 25, which are arranged sequentially along the conveying direction of the label roll 5. The first traction roller 221, the traction member 226, the second traction roller 222, and the third traction roller 223 guide the label roll to the label peeling plate 24 and ensure that the label roll is horizontal so that the working end 31 of the adsorption assembly 3 can adsorb the label.

[0028] The working end 31 is composed of a first adsorption substrate 311, a second adsorption substrate 312 and a third adsorption substrate 313. An air channel 317 for connecting the driving device is provided on the second adsorption substrate 312. The third adsorption substrate 313 is provided with regularly arranged air holes 3131. A suction cup 314 is installed below the third adsorption substrate. When the adsorption component 3 adsorbs the label, the driving device performs a vacuum operation, which acts on the suction cup 314 through the air channel 317, the air cavity 316 and the air holes 3131 to adsorb the label from the label roll 5.

[0029] For labels made of different materials, both soft and hard, the adsorption components are designed with two different structures to handle different situations:

[0030] Adsorption component structure 1: For labels made of harder materials, the adsorption component 3 is equipped with a working end 31 and a first adsorption slide rail 32. When adsorbing the label, the working end 31 is pressed down along the Z-axis direction to the label peeling plate 24 by the first adsorption slide rail 32 under the action of the driving device. The working end 31 remains horizontal. The driving device draws a vacuum so that the suction cup 314 at the bottom of the working end 31 adsorbs the label. At this time, the working end 31 rises back along the Z-axis direction along the first adsorption slide rail 32, and the label peeling plate 24 retracts along the Y-axis direction along the label peeling slide rail, exposing the material transported by the feeding component 4 below. The working end 31 is pressed down to the material along the Y-axis direction along the first adsorption slide rail 32. At this time, the driving device releases air so that the suction cup 314 releases the label while pressing the label evenly. The multi-pore design ensures even adhesion and fixes the label to the material.

[0031] Adsorption Component Structure Two: For labels made of softer materials, the adsorption component requires a different structure. Adsorption component 3 includes a working end 31, a first adsorption slide rail 32, and a second adsorption slide rail 33. The first adsorption substrate 311 has a connecting rod 341 on the working end a side 31a. The connecting rod 341 has an elongated movable hole 342 that connects to the lifting part 34. The working end b side 31b is hinged to a hinge seat 331 below the second adsorption slide rail 33. A roller is also provided on the working end b side 31b. A suction cup 314 is installed below the working third adsorption substrate 313 and extends outward from the working end b side 31b, with the extension position below the roller 315. When adsorbing a label, the working end 31, under the action of the driving device, is pressed down along the Z-axis direction by the first adsorption slide rail 32 onto the label peeling plate 24. The working end 31 remains horizontal. The driving device creates a vacuum, causing the suction cup 314 at the bottom of the working end 31 to adsorb the label. At this time, the working end 31 rises along the first adsorption slide rail 32 in the Z-axis direction, and the label peeling plate 24 retracts along the label peeling slide rail 241 in the Y-axis direction, exposing the material transported by the feeding component 4 below. The working end 31 moves along the first adsorption slide rail 32 in the Y-axis direction and presses down onto the surface of the material. At this time, the lifting part 34 moves upward, and the connection between the lifting part 34 and the connecting rod 341 moves in the elongated movable hole 342, causing the working end a side 31a to rotate upward about the hinge seat 331 as the axis. The roller 315 located on the working end b side 31b presses the label part adsorbed by the suction cup 314 extending below onto the material. Under the action of the driving device, the working end 31 moves along the second adsorption slide rail in the X-axis direction, driving the roller 315 to perform a rolling operation on the released label from one end to the opposite end, ensuring the flatness and firmness of the softer label, and avoiding wrinkles and bubbles that are easily generated when flatly pasted.

[0032] The driving device is not shown in the accompanying drawings of this invention. The driving device may be a vacuum pump.

[0033] Before the label feeding assembly 2 feeds the label roll 5 to the label peeling plate 24, the detection unit 23 located between the second traction roller 222 and the third traction roller 223 detects whether there is a label on the label roll 5, ensuring that there is a label on the label roll 5 when the adsorption assembly 3 is working at the label peeling plate 24. After the adsorption assembly 3 adsorbs the label on the label tape, the label feeding assembly 2 continues to operate, so that the label roll 5 is guided by the fourth traction roller 224, the fifth traction roller 225 and the traction member 226 and then wound up in the take-up unit 25.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
