Description

Technical Field

[0001] The utility model relates to the field of labeling machines, and particularly relates to a round rod label overlapping attaching machine. Background Art

[0002] Generally, for labeling round rod-shaped products or round tubular products, manual operation is mostly adopted. However, in order to ensure the consistent attachment position and reduce the labor intensity, a labeling machine is used. For example, in the utility model patent with the authorization announcement date of Mar. 21, 2023 and the announcement number of CN218662795 U, a labeling device for cosmetic hoses is disclosed. It leaks the label at a specified position through a paper feeding mechanism, and then the disk drives the cosmetic hose to the corresponding position to stick the label onto the cosmetic hose. Subsequently, the third cylinder indirectly drives the cosmetic hose to rotate to wind the label around the cosmetic hose to complete the labeling. However, this kind of labeling machine is only applicable to round tube products conveyed by a disk and cannot realize the overlapping attachment of labels on round rod-shaped products horizontally conveyed on a line body. Summary of the Utility Model

[0003] To overcome the above disadvantages, the purpose of the utility model is to provide a round rod label overlapping attaching machine that can overlap and attach labels on a round rod on a line body.

[0004] To achieve the above purpose, one of the technical solutions adopted by the utility model is: a round rod label overlapping attaching machine, including a conveying line body that drives a round rod product to move from one end of the conveying line body to the other end. An installation frame is arranged above the conveying line body, and the installation frame is driven to lift and translate by a transfer manipulator. A semi-open rotating assembly is arranged on the installation frame. The semi-open rotating assembly includes an arc support frame and an arc rotating member. An elevating cylinder for driving the arc support frame to lift is arranged on the installation frame. Both the arc support frame and the arc rotating member are in a semi-open shape, and their openings both face the round rod product on the conveying line body. The arc rotating member is slidably arranged on the inner arc of the arc support frame. Elastic cloth is connected and fixed to both ends of the arc rotating member. A servo motor for driving the arc rotating member to rotate is arranged on the arc support frame. When the semi-open rotating assembly is moved to the labeling position of the round rod product, through the drive of the servo motor, the elastic cloth can rotate along the circumference of the round rod product.

[0005] The beneficial effects of the circular rod label overlapping attachment machine of the present utility model are as follows: The lifting and translation of the mounting frame are driven by the transfer manipulator, and then the semi-open rotating assembly is driven to move towards the circular rod products on the conveyor line body. Through the cooperative setting of the arc support frame, the arc rotating member, the elastic cloth, and the servo motor, the elastic cloth is forced to rotate along the circumference of the circular rod product, so that the label originally attached horizontally to the circular rod product rotates around the circumference of the circular rod product due to the rotation of the elastic cloth, and the overlapping attachment of the label on the circular rod product can be realized. This circular rod label overlapping attachment machine is applicable to circular rods or circular tube products transferred on the line body conveyor.

[0006] Preferably, a gear is provided on the output shaft of the servo motor, and a rack is provided on the outer arc of the arc rotating member, and the gear meshes with the rack. By using the cooperation of the gear and the rack, precise rotation of the arc rotating member can be achieved.

The elastic cloth is connected in a sleeved manner, making the installation of the elastic cloth convenient and fast. In addition, once the elasticity of the elastic cloth is lost, it can be quickly replaced.

[0008] Preferably, a positioning component is provided on the mounting frame, and the positioning component is used to position the circular rod product on the conveyor line body. When the elastic cloth rotates to attach the label, the circular rod product is pre-positioned by the positioning component, which can prevent the circular rod product from rotating with the elastic cloth, thereby causing defects in the label attachment.

[0009] Preferably, the positioning component includes a positioning cylinder and a positioning block. The positioning cylinder is vertically arranged on the mounting frame, the telescopic shaft of the positioning cylinder faces downward, and the positioning block is arranged at the end of the telescopic shaft of the positioning cylinder. During positioning, the positioning block is driven by the positioning cylinder to press against the surface of the circular rod product.

Detailed Description of the Invention

[0024] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model.

[0025] Referring to Figures 1-5 As shown, this embodiment discloses a round rod label overlapping attaching machine, which includes a conveying line body 10. The conveying line body 10 drives the round rod product 80 to move from one end of the conveying line body 10 to the other end. An installation frame 20 is arranged above the conveying line body 10. The installation frame 20 is driven to lift and translate by a transfer manipulator 30. The transfer manipulator 30 in this embodiment adopts a two-axis transfer module. A semi-open rotating assembly 40 is arranged on the installation frame 20. The semi-open rotating assembly 40 includes an arc support frame 41 and an arc rotating member 42. An elevating cylinder 43 for driving the arc support frame 41 to lift is arranged on the installation frame 20. Both the arc support frame 41 and the arc rotating member 42 are semi-open, and the openings of both face the round rod product 80 on the conveying line body 10. The arc rotating member 42 is slidably arranged on the inner arc 41a of the arc support frame 41. Elastic cloth is connected and fixed at both ends of the arc rotating member 42. A servo motor 45 for driving the arc rotating member 42 to rotate is arranged on the arc support frame 41. When the semi-open rotating assembly 40 is moved to the labeling position of the round rod product 80, driven by the servo motor 45, the elastic cloth can rotate along the circumference of the round rod product 80.

[0026] As Figure 3 、 Figure 4 shown, a gear is arranged on the output shaft of the servo motor 45 in this embodiment, and a rack is arranged on the outer arc of the arc rotating member 42. The gear meshes with the rack. In the attached drawings, the gear and the rack are not shown. By using the cooperation of the gear and the rack, precise rotation of the arc rotating member 42 can be achieved.

[0027] As Figure 3 、 Figure 4 shown, connecting rods 44 are arranged at both ends of the arc rotating member 42, and both ends of the elastic cloth are sleeved on the connecting rods 44.

[0028] As Figure 1 shown, a positioning assembly 50 is arranged on the installation frame 20 in this embodiment. The positioning assembly 50 is used to position the round rod product 80 on the conveying line body 10. When the elastic cloth rotates the label 81, the round rod product 80 is pre-positioned by the positioning assembly 50 to prevent the round rod product 80 from rotating along with the elastic cloth. The positioning assembly 50 in this embodiment includes a positioning cylinder 51 and a positioning block 52. The positioning cylinder 51 is vertically arranged on the installation frame 20, and the telescopic shaft of the positioning cylinder 51 faces downward. The positioning block 52 is arranged at the end of the telescopic shaft of the positioning cylinder 51. During positioning, the positioning block 52 presses the surface of the round rod product 80 to prevent it from rotating.

[0029] As Figure 1 shown, a label adsorption assembly 60 and a label printer 70 are provided on the mounting bracket 20. The label printer 70 is arranged on one side of the conveying line body 10. The label adsorption assembly 60 is used to transfer the label at the outlet 71 of the label printer 70 to the surface of the round rod product 80. The label adsorption assembly 60 in this embodiment includes an adsorption cylinder 61 and a vacuum adsorption head 62. The adsorption cylinder 61 is installed on the mounting bracket 20, and the vacuum adsorption head 62 is driven by the adsorption cylinder 61 to move up and down.

[0030] As Figure 1 shown, the conveying line body 10 includes a frame 11, a driving wheel, a driven wheel, a transmission chain, a motor, and a product support frame 12. The driving wheel and the driven wheel are rotatably arranged on the frame 11. The transmission chain is sleeved on the driving wheel and the driven wheel. The motor is fixed on the frame 11 and drives the transmission chain to drive. At least two sets are provided with the driving wheel, the driven wheel, and the transmission chain. A plurality of product support frames 12 are provided and are evenly fixed on the transmission chain at intervals. As Figure 2 shown, a V-shaped card slot 13, a support seat 14, and a limit slot 15 that are in imitation matching with the round rod product 80 are provided at the upper end of each product support frame 12. Through the imitation design, the round rod product 80 can be better positioned.

[0031] The working principle of this embodiment is:

[0032] The transfer manipulator 30 first drives the mounting bracket 20 to move towards the label printer 70 and cooperates with the adsorption cylinder 61 until the vacuum adsorption head 62 vacuum-adsorbs the label 81 at the outlet 71 of the label printer 70. The vacuum adsorption head 62 adsorbs the smooth surface of the label 81, and then driven by the transfer manipulator 30, the vacuum adsorption head 62 transfers the label 81 to the part of the round rod product 80 where the label 81 is to be pasted. The adsorption cylinder 61 presses the flat label 81 onto the surface of the round rod product 80 until the label 81 adheres to the surface of the round rod product 80. As Figure 5 shown, at this time, only the part where the label 81 is tangent to the surface of the round rod product 80 adheres. Then the transfer manipulator 30 drives the mounting bracket 20 to move until the semi-open rotating assembly 40 is located directly above the label 81. At this time, the lifting cylinder 43 drives the arc support frame 41 to move down, and the arc rotating member 42 moves down accordingly. The round rod product 80 enters from the opening into the inner arc of the arc support frame 41 and the arc rotating member 42 until the elastic cloth contacts the surface of the round rod product 80 (i.e., contacts the smooth surface of the label 81). The servo motor 45 is started to drive the arc rotating member 42 to rotate along the inner arc of the arc support frame 41, so that the elastic cloth rotates along the circumference of the round rod product 80, so that the label 81 originally attached horizontally to the round rod product 80. The label 81 in this embodiment needs to overlap at the head and tail (i.e., the width of the label 81 is greater than the circumference of the round rod product 80). There are two ways to paste with the head and tail overlapping. The first pasting method isFigure 6 As shown, one end of the label 81 is attached to the smooth surface of the other end. The second pasting method is Figure 7 As shown, the pasting surfaces at both ends of the label 81 are fitted together; the pasting of the two can obtain two different label pasting methods by adjusting the rolling direction and angle of the moving elastic cloth.

[0033] When performing the first pasting method, in order to completely attach the label 81 to the surface of the round rod product 80, the servo motor 45 first drives the elastic cloth to rotate clockwise by a first predetermined angle, and the elastic cloth returns to its original position. After returning, the servo motor 45 then drives the elastic cloth to rotate counterclockwise for more than one week, so that the label 81 can be completely overlapped and attached to the round rod product 80. Of course, the round rod product 80 is not limited to being solid, and can also be a round rod product 80 with a hollow interior.

[0034] When performing the second pasting method, the middle part of the label 81 is pre-attached to the round rod product 80. The servo motor 45 first drives the elastic cloth to rotate clockwise by a second predetermined angle, and the elastic cloth returns to its original position. After returning, the servo motor 45 then drives the elastic cloth to rotate counterclockwise by a second predetermined angle, and the two pasting surfaces of the label 81 can be pasted.

[0035] The above embodiments are only for explaining the technical concept and features of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
