Labeling assembly line capable of achieving multi-face labeling

Abstract

The invention discloses a labeling assembly line capable of achieving multi-face labeling, and relates to the technical field of labeling assembly lines. Comprising an assembly line mounting frame, an annular assembly line is mounted in the assembly line mounting frame, and a plurality of carriers used for conveying labeled products are arranged on the annular assembly line; two labeling mechanisms are arranged on the assembly line mounting frame and arranged along the moving path of the carrier, and a turnover mechanism is arranged between the two labeling mechanisms. By arranging the labeling mechanism, when a material table passes through an end wheel, a label is separated from a material belt due to an overlarge bending angle, and due to the fact that the height of the end wheel is lower than that of an unwinding wheel and a winding wheel, the label is in an inclined state when separated from the material belt, one end of the label can make contact with the surface of a labeled product, and then under cooperation of an auxiliary brush, the labeling effect is improved. The label is attached to the labeled product; due to the fact that the auxiliary brush is of a flexible structure, a label can be better pressed on the curved surface of a labeled product in an auxiliary mode.

[0042] The beneficial effects of this invention are as follows:

[0043] 1. This invention, by setting up a labeling mechanism, enables the conveyor belt to transport the product to be labeled to the area below the labeling mechanism via a circular conveyor belt. Based on the operation of the drive motor, the material belt moves. When the material platform passes the end roller, the label separates from the material belt due to the excessive bending angle. Since the height of the end roller is lower than the unwinding and rewinding rollers, the label is in an inclined state when separated from the material belt, allowing one end of the label to contact the surface of the product to be labeled. Then, with the cooperation of the auxiliary brush, the label is attached to the product to be labeled. Since the auxiliary brush has a flexible structure, it can better assist in pressing the label onto the curved surface of the product to be labeled.

[0044] 2. By setting up a flipping mechanism, the present invention can use two first electric clamping cylinders to clamp the labeled product, raise the height by an electric lifting cylinder, and temporarily clamp it by a second electric clamping cylinder based on the rotation of the reciprocating flipping component at a set angle. After the reciprocating flipping component drives the clamping frame to reset, the first electric clamping cylinder clamps it again, and lowers the height based on the electric lifting cylinder to put the labeled product back into the carrier, thus achieving a certain angle of flipping; so that the next labeling mechanism can label at different positions.

[0045] 3. By setting up an auxiliary pressing mechanism, the present invention can drive the first auxiliary pressing roller to rotate based on the operation of the pressure roller motor, thereby assisting in pressing the labeled products and improving the firmness of the label; the second lifting adjustment frame can adjust the height of the second lifting seat to ensure accurate pressing of the structure.

[0046] 4. By setting up a material handling mechanism, this invention uses only a single power source, a horizontal electric telescopic cylinder, to achieve the purpose of picking up and transporting labeled products. Attached Figure Description

Detailed Implementation

[0055] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0056] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0057] Example 1:

[0058] A labeling production line capable of multi-sided labeling, such as Figure 1-7 As shown, the system includes a production line mounting frame 1, within which a circular production line is installed. Multiple carriers 16 for conveying labeled products 18 are arranged on the circular production line. Two labeling mechanisms are mounted on the production line mounting frame 1, arranged along the movement path of the carriers 16, and a flipping mechanism is provided between the two labeling mechanisms. Each labeling mechanism includes:

[0059] The first lifting adjustment frame 13 is installed on the outer wall of one side of the assembly line mounting frame 1;

[0060] The first lifting seat 14 is installed on the first lifting adjustment frame 13;

[0061] Mounting plate 3 is installed on one side of the outer wall of the first lifting seat 14. On one side of the mounting plate 3, there are rotatable unwinding wheel 2 and winding wheel 4 for winding and unwinding the label material tape. Multiple guide wheels 17 are installed on the mounting plate 3.

[0062] End wheel 20 is installed on the outer wall of one side of the mounting plate 3. One end of the label tape is wound on the take-up wheel 4, and the other end is wound on the unwind wheel 2 after passing through the end wheel 20 and the guide wheel 17. A drive motor 12 for controlling the winding is installed on one side of the mounting plate 3.

[0063] Auxiliary brush 19 is installed on the outer wall of one side of the mounting plate 3, and the auxiliary brush 19 is located diagonally above the end wheel 20;

[0064] The lifting adjustment method of the first lifting adjustment frame 13, such as lifting adjustment through a screw, slide rail or other structure, and the winding method controlled by the drive motor 12, such as transmission through a transmission wheel, belt or other means, are existing technologies and will not be described in detail here.

[0065] By setting up a labeling mechanism, the labeling product 18 to be labeled can be conveyed to the bottom of the labeling mechanism via the circular conveyor 16. Based on the operation of the drive motor 12, the material belt moves. When the material platform passes the end roller 20, the label separates from the material belt due to the excessive bending angle. Since the height of the end roller 20 is lower than the unwinding roller 2 and the winding roller 4, the label is in an inclined state when it separates from the material belt, so that one end of the label can contact the surface of the labeling product 18. Then, with the cooperation of the auxiliary brush 19, the label is attached to the labeling product 18. Since the auxiliary brush 19 is a flexible structure, it can better press the label onto the curved surface of the labeling product 18.

[0066] To achieve the flipping of the labeled product 18; such as Figure 3 As shown, the flipping mechanism includes:

[0067] The clamping frame has a downward-opening U-shaped structure. The clamping frame is equipped with a first electric clamping cylinder 22 for clamping on both sides. The carrier 16 has side grooves 34 on both sides.

[0068] Reciprocating tilting assembly, used to control the reciprocating tilting of the clamping frame;

[0069] The electric lifting cylinder 15 has a reciprocating tilting assembly installed at its output end, and the height is controlled by the electric lifting cylinder 15.

[0070] The fixed frame 11 has a U-shaped structure with the opening facing downward. The two ends of the fixed frame 11 are installed on both sides of the assembly line mounting frame 1. Two symmetrical second electric clamping cylinders 23 are installed on the fixed frame 11. The output ends of the first electric clamping cylinder 22 and the second electric clamping cylinder 23 are provided with anti-slip clamping blocks 24.

[0071] By setting up a flipping mechanism, the labeling product 18 can be clamped by two first electric clamping cylinders 22, raised in height by electric lifting cylinder 15, and temporarily clamped by second electric clamping cylinder 23 based on the rotation of the reciprocating flipping component at a set angle. After the reciprocating flipping component drives the clamping frame to reset, the first electric clamping cylinder 22 clamps it again, and lowers the height based on electric lifting cylinder 15, so that the labeling product 18 can be put back into the carrier 16, achieving a certain angle of flipping; so that the next labeling mechanism can label at different positions.

[0072] To facilitate control of the reciprocating rotation of the structure; such as Figure 4 As shown, the reciprocating flipping component includes:

[0073] The arc-shaped gear frame 26 has a clamping frame fixed to the outer wall of one side of the arc-shaped gear frame 26;

[0074] Arc rod 25 is located outside arc gear frame 26. The arc center of arc rod 25 coincides with that of arc gear frame 26, and the arc of arc rod 25 and arc gear frame 26 is greater than 180 degrees. The end of arc rod 25 and the end of arc gear frame 26 are fixedly connected by bracket.

[0075] The lifting frame 21 is fixed to the output end of the electric lifting cylinder 15. One end of the lifting frame 21 has an arc-shaped structure that matches the arc-shaped rod 25. The arc-shaped rod 25 passes through and is slidably connected to the inner wall of one end of the lifting frame 21.

[0076] A rotation drive unit is mounted on the lifting frame 21 and is used to drive the arc-shaped gear frame 26 to rotate.

[0077] By setting up a reciprocating rotation component, the rotating drive unit can work to drive the arc-shaped gear frame 26 to rotate reciprocally, thereby achieving reciprocating rotation.

[0078] To facilitate the reciprocating rotation of the driving structure; such as Figure 4 As shown, the rotation drive unit includes:

[0079] A rotation control motor is mounted on the lifting frame 21.

[0080] The rotation control gear has its shaft connected to the output end of the rotation control motor. The inner side of the arc-shaped gear frame 26 is provided with convex teeth distributed along the arc, which mesh with the rotation control gear.

[0081] To facilitate stable transport of the carrier 16; such as Figure 5As shown, multiple mounting pieces are fixed on the outside of the assembly line mounting frame 1. Limiting strips 35 are fixed on the mounting pieces. The shape of the limiting strips 35 is adapted to the assembly line mounting frame 1. An annular limiting channel is formed between the limiting strips 35 and the assembly line mounting frame 1. A limiting block 36 is fixed on one side of the outer wall of the carrier 16. When the carrier 16 is conveyed on the annular assembly line, the limiting block 36 is located in the annular limiting channel.

[0082] The width of the annular limiting channel is greater than twice the thickness of the limiting block 36, but less than twice the thickness of the limiting block 36.

[0083] By setting limit bars 35 and limit blocks 36, the carrier 16 can be better limited, making it more stable to be transported along the circular conveying path, thus improving reliability.

[0084] To facilitate auxiliary pressing; such as Figure 2 As shown, an auxiliary pressing mechanism is installed on the assembly line mounting frame 1, and the auxiliary pressing mechanism includes:

[0085] The second lifting adjustment frame 7 is installed on one side of the assembly line mounting frame 1;

[0086] The second lifting seat 9 is installed on the second lifting adjustment frame 7;

[0087] The first auxiliary pressure roller 10 is rotatably mounted on one side of the second lifting seat 9;

[0088] The pressure roller motor 8 is mounted on the second lifting seat 9, and the output end of the pressure roller motor 8 is connected to the shaft of the first auxiliary pressure roller 10.

[0089] By setting up an auxiliary pressing mechanism, the first auxiliary pressing roller 10 can be driven to rotate based on the operation of the pressure roller motor 8, and the labeling product 18 passing by can be pressed to improve the firmness of the label; the second lifting adjustment frame 7 can adjust the height of the second lifting seat 9 to ensure accurate pressing of the structure.

[0090] The specific adjustment method can also be the conventional adjustment method such as lead screw adjustment, which will not be elaborated here.

[0091] To facilitate further pressing; such as Figure 2 As shown, a support arm is installed on one side of the assembly line mounting frame 1, and a second auxiliary pressure roller 5 is rotatably mounted on the support arm via a shaft.

[0092] For ease of material handling; such as Figure 1 , Figure 5-7 As shown, a material handling mechanism is installed on the assembly line mounting frame 1. The material handling mechanism includes:

[0093] The support frame 6 has a fixed frame 28 installed on its top. Inside the fixed frame 28, there are two symmetrical guide frames 29. The guide frames 29 are inverted right trapezoidal structures. The adjacent sides of the two guide frames 29 are parallel and vertical. A vertical channel is formed between the two guide frames 29. One side of the guide frame 29 is fixed to the fixed frame 28 by a connecting frame 38. A horizontal channel is formed between the top of the guide frame 29 and the fixed frame 28. The top of the vertical channel is connected to the horizontal channel.

[0094] The limiting frame 33 is fixed to the top of the support frame 6. The middle part of the limiting frame 33 has a V-shaped structure. The lowest point of the V-shaped structure is located directly above the conveying path of the labeled product 18. A strip-shaped opening is provided in the middle of the limiting frame 33.

[0095] The material taking tube 41 is located inside the strip-shaped opening. A suction cup 42 is fixed to the bottom end of the material taking tube 41. A lower end plate 40 is fixed to the top of the material taking tube 41. An elastic airbag 30 is fixed to the top of the lower end plate 40. An upper end plate 31 is fixed to the top of the elastic airbag 30. Upper rollers are installed on the side of the upper end plate 31. Lower rollers 43 are installed on both sides of the material taking tube 41. A spring 44 is installed between the upper end plate 31 and the lower end plate 40. The spring 44 is in a compressed state. The elastic airbag 30, the material taking tube 41 and the suction cup 42 are connected internally.

[0096] One-way limiting ramp 37, one end of which is rotatably mounted on the acute angle end of guide frame 29 via a shaft fitted with a spring. A limiting piece 46 is fixed on the side of guide frame 29, and a side protrusion 45 is fixed on the side of one-way limiting ramp 37. Based on the limiting piece 46, the side protrusion 45 and the spring, the one-way limiting ramp 37 achieves one-way limiting of the movement of the upper roller.

[0097] The guide section is used to ensure that the upper end plate 31 and the lower end plate 40 maintain the same horizontal position during movement;

[0098] Translation control unit, used to control the reciprocating translation of the lower end plate 40.

[0099] To improve structural stability; such as Figure 6 As shown, the guide part includes a guide rod and a guide frame 39. The guide rod and the guide frame 39 are both fixed on the lower end plate 40, and the upper end plate 31 is slidably connected to the outer wall of the guide rod and the guide frame 39.

[0100] By setting up a guide section, the misalignment of structures such as the elastic airbag 30 can be avoided, thus improving reliability.

[0101] To facilitate control of structural translation; such as Figure 5 , Figure 6As shown, the translation control unit includes a horizontal electric telescopic cylinder 27, which is mounted on the support frame 6. The output end of the horizontal electric telescopic cylinder 27 is fixed with a sliding sleeve 32. Ribs are provided on the guide frame 39, and the guide frame 39 is slidably mounted in the sliding sleeve 32.

[0102] To facilitate the removal of the labeled product 18 from the suction cup 42, a structure such as an electric lever can be installed at the end of the movement trajectory or movement path of the suction cup 42 to peel the labeled product 18 off the suction cup 42; the shape of the bottom surface of the suction cup 42 should be adapted to the labeled product 18 to ensure the stability and reliability of the suction.

[0103] In order to further improve the suction effect, a spray device can be set in the movement path of the suction cup 42. By spraying and humidifying the suction cup 42, the sealing performance is improved when the suction cup 42 comes into contact with the labeled product 18, and the risk of falling off during suction is reduced; the specifics are not elaborated in this invention.

[0104] By setting up a material handling mechanism, in the initial state, the material handling tube 41 is located at one end of the strip opening. At this time, the upper roller is located on the side of the one-way limiting inclined plate 37 away from the horizontal channel. The horizontal electric telescopic cylinder 27 works to push the guide frame 39. During the process, the upper roller contacts the one-way limiting inclined plate 37. Since the side protrusion 45 of the one-way limiting inclined plate 37 is limited by the limiting piece 46, the one-way limiting inclined plate 37 remains stationary. Subsequently, under the support of the spring 44, the lower roller 43 rolls on the top surface of the limiting frame 33, and the upper roller rolls along the inclined surface of the one-way limiting inclined plate 37 and the guide frame 29. During this period, the elastic airbag 30 is gradually compressed to expel the internal gas.

[0105] As the structure continues to move, the lower roller 43 moves to the bottom of the V-shaped structure of the limiting frame 33. At this time, due to the decrease in height, the suction cup 42 can contact the labeled product 18 at the picking position. At the same time, the upper roller moves to the vertical channel. Based on the deformation and recovery force of the spring 44 and the elastic airbag 30 itself, the upper roller moves upward along the vertical channel. Since the elastic airbag 30, the picking tube 41 and the suction cup 42 are connected, and the bottom of the suction cup 42 is blocked by the labeled product 18, the labeled product 18 is picked up under the action of air pressure.

[0106] The horizontal electric telescopic cylinder 27 controls the structure to reset. At this time, the upper roller moves along the horizontal channel and eventually pushes the one-way limit inclined plate 37 to deflect and return to its original position. The entire process uses only the single power source of the horizontal electric telescopic cylinder 27 to achieve the purpose of picking up and transporting the labeled product 18.

[0107] To ensure better implementation, the suction cup 42 is in position before suction begins. A non-slip sleeve with a certain friction is provided on the upper plate 31. The non-slip sleeve only slows down the upward sliding of the upper plate 31 and does not completely prevent it from sliding upward. Based on this, when picking up the material, the upper plate 31 has not yet moved to the top after the suction cup 42 contacts the top surface of the labeled product 18. As time progresses, the upper plate 31 eventually moves to the top, achieving reliable suction of the labeled product 18.

[0108] In practical applications, the friction can be adjusted to meet the required standard by changing the size and material of the anti-slip sleeve.

[0109] For the parts not disclosed in detail in this invention, those skilled in the art can ensure the smooth implementation of the solution of this invention based on common sense, normal logical thinking and existing technology.

[0110] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
