Description

Technical Field

[0001] This invention relates to the field of labeling machine technology, and in particular to a linkage labeling mechanism that enables label changing without stopping the machine. Background Technology

[0002] Labeling machines are devices that use adhesives to affix labels, such as paper and metal foil, to specified packaging containers. They are an indispensable component of the modern packaging industry and are widely used for automatic labeling of bottled products in the food, pharmaceutical, health product, cosmetic, pesticide, and other light industrial sectors. With technological advancements and rising living standards, consumers' demands for packaging quality are increasing, and many products require labeling for differentiation and better marketing. However, automatic labeling machines require downtime for label replacement, which significantly impacts the labeling process, affects upstream processes, reduces actual production efficiency, and hinders product manufacturing. Summary of the Invention

[0003] To address the aforementioned technical problems, a linkage labeling mechanism that enables non-stop label changing is provided.

[0004] To achieve the above objectives, this invention discloses a linkage labeling mechanism for non-stop label changing, comprising a frame and a conveyor belt assembly horizontally installed inside the frame. At least two labeling tables are installed behind the conveyor belt assembly. A cylinder slide rail module perpendicularly arranged to the conveyor belt assembly is installed on the frame below the labeling tables. The labeling tables are mounted on the sliders of the cylinder slide rail modules at corresponding positions. A linkage mechanism is installed on the conveyor belt assembly. The linkage mechanism includes a roller label belt and a movable baffle located on both sides of the top of the conveyor belt assembly. The roller label belt is positioned closer to the labeling table. A spacing adjustment component is positioned on the outer side of the movable baffle. The bottom of the roller label belt and the spacing adjustment component are fixedly connected to a mounting plate. The mounting plate is connected to the slider of the lower transverse slide rail module. The control unit of the labeling table is electrically connected to the control unit of the transverse slide rail module.

[0005] Furthermore, the top of the conveyor belt assembly is equipped with fixing plates at the input and output ends. The fixing plates include a rear baffle near the labeling table and a front baffle on the other side. Between the two sets of rear baffles, lifting baffles corresponding to the number and position of the labeling table are respectively provided. The bottom of each lifting baffle is connected to two sets of lifting cylinders. The lifting baffles are adjusted in height according to the position of the linkage mechanism to form a rear guard structure with the rear baffles and the rolling label belt.

[0006] Furthermore, hollow guide tubes are provided at the upper and lower ends of the inner side of the front baffle, and the two ends of the movable baffle move between the two front baffles through guide rods inserted into the hollow guide tubes.

[0007] Furthermore, the spacing adjustment assembly includes an active adjustment mechanism located in front of the movable baffle and a driven adjustment mechanism located on both sides of the active adjustment mechanism. The active adjustment mechanism includes a first gear connected to the motor output shaft, a second gear meshing with the side of the first gear, a rack meshing with the top of the second gear, and the end of the rack being connected to the movable baffle.

[0008] Furthermore, a hexagonal bar is inserted and installed at the center of the second gear, and the end of the hexagonal bar is connected to the driven adjustment mechanism through a coupling and a round rod. The driven adjustment mechanism is connected to the front baffle at the corresponding position.

[0009] Furthermore, the input end of the conveyor belt assembly is equipped with a bottle-separating mechanism. The bottle-separating mechanism includes a screw adjusting block located behind the conveyor belt assembly. An adjusting motor is installed at the bottom of the screw adjusting block. The output end of the adjusting motor passes through the screw adjusting block and is connected to the bottle-separating plate above. A rubber ring is installed on the circumferential surface of the bottle-separating plate. The bottle-separating plate extends from the opening of the rear baffle to the position between the front baffle and the rear baffle to separate the packaging material into bottles.

[0010] Furthermore, the labeling station includes an unwinding shaft and a rewinding shaft. The labels on the unwinding shaft are wound around multiple sets of tensioning shafts and wound around the rewinding shaft from the label exit position. A brake shaft is provided on the side of the unwinding shaft.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention discloses a linkage labeling mechanism that realizes label changing without stopping the machine. When the label rolls on one set of labeling tables are exhausted, another set of labeling tables with new label rolls promptly fills the gap and moves close to the conveyor belt assembly. The linkage mechanism moves according to the position of the newly filled labeling table, so that the labeling machine can realize automatic roll changing without stopping the machine, which greatly saves the time of stopping to change rolls and adjust, and improves work efficiency.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] One embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 3As shown, two sets of labeling stations 2 are installed behind the conveyor belt assembly 1. The labeling station on the left is named the first station, and the labeling station on the right is named the second station. The two sets of labeling stations have the same structure. A cylinder slide rail module 21, which is perpendicular to the conveyor belt assembly 1, is installed on the frame below the labeling station 2. The control units of the cylinder slide rail modules below the first station and the second station are electrically connected to form an interlock control. When multiple sets of labeling stations exist, it is ensured that only one set performs the labeling operation to avoid duplicate labeling. The labeling station 2 is installed on the slider of the cylinder slide rail module 21 at the corresponding position. A linkage mechanism 3 is installed on the conveyor belt assembly 1. The linkage mechanism 3 includes components located on the conveyor belt assembly... The top two sides of component 1 have a roller label belt 31 and a movable baffle 32. The roller label belt 31 is located near the labeling table 2. The movable baffle 32 has a spacing adjustment component 4 on its outer side. The bottom of the roller label belt 31 and the spacing adjustment component 4 are fixedly connected to the mounting plate 33. The mounting plate 33 is connected to the slider of the lower transverse slide rail module 34. The transverse slide rail module drives the roller label belt and the movable baffle to move synchronously. The mounting plate is also connected to a drag chain structure. The control unit of the labeling table 2 is electrically connected to the control unit of the transverse slide rail module 34. When the empty roll of the labeling table moves backward, the new full roll of the labeling table moves forward. The transverse slide rail module drives the linkage mechanism to move to the front of the new labeling table to form a new labeling structure.

[0024] like Figure 6 and Figure 7 As shown, the top of the conveyor belt assembly 1 is equipped with fixing plates at the input and output ends. The fixing plates include a rear baffle 12 near the labeling table 2 and a front baffle 11 on the other side. Lifting baffles 13 corresponding to the number and position of the labeling tables 2 are respectively arranged between the two sets of rear baffles 12. The bottom of each lifting baffle 13 is connected to two sets of lifting cylinders. In this embodiment, the linkage mechanism is located in front of the second station. At this time, the lifting cylinder in front of the second station controls the lifting baffle to descend to provide space for the roller label belt. The lifting baffle in front of the first station is in the rising state, forming a rear guard structure with the rear baffle and the roller label belt.

[0025] like Figure 7 and Figure 8 As shown, hollow guide tubes 111 are provided at the upper and lower ends of the inner side of the front baffle 11. The two ends of the movable baffle 32 move between the two front baffles 11 through guide rods 321 inserted into the hollow guide tubes 111, providing guidance for the movement of the movable baffle. At the same time, the position-adjustable movable baffle and the guide rods form the front edge structure.

[0026] like Figure 3 and Figure 8As shown, the spacing adjustment assembly 4 includes an active adjustment mechanism 41 located in front of the movable baffle 32 and driven adjustment mechanisms 42 located on both sides of the active adjustment mechanism 41. The active adjustment mechanism 41 includes a first gear 411 connected to the motor output shaft (the motor is not shown in the attached drawing). A second gear 412 is meshed on the side of the first gear 411, and a rack 413 is meshed on top of the second gear 412. The end of the rack 413 is connected to the movable baffle 32. The spacing of the top edge of the conveyor belt assembly is adjusted through the gear transmission structure to accommodate the conveying of packaging materials of different specifications. A power rod 414 is inserted into the center of the second gear 412. The end of the power rod 414 is connected to the driven adjustment mechanism 42 through a coupling and a connecting rod. The driven adjustment mechanism 42 is connected to the front baffle 11 at the corresponding position. Figure 8 As shown, in this embodiment, the power rod adopts a hexagonal bar structure. Since the power rod is a driving component, it needs to complete both rotation and sliding actions. Traditional connection structures require keyway connections, but the power rod of this application is relatively long, so the keyway structure is not suitable. The hexagonal bar structure can meet all the requirements of the power rod mentioned above while reducing the installation structure.

[0027] like Figure 6 As shown, a bottle-separating mechanism 5 is installed at the input end of the conveyor belt assembly 1. The bottle-separating mechanism 5 includes a screw adjusting block 51 located behind the conveyor belt assembly 1. An adjusting motor 52 is installed at the bottom of the screw adjusting block 51. The output end of the adjusting motor 52 passes through the screw adjusting block 51 and is connected to the upper bottle-separating plate 53. In this embodiment, the bottle-separating plate has a circular structure. A rubber ring is installed on the circumference of the bottle-separating plate 53 to avoid scratching the packaging material. The bottle-separating plate 53 extends from the opening of the rear baffle 12 to the position between the front baffle 11 and the rear baffle 12 to separate the packaging material into bottles. By adjusting the motor to apply force to the bottle-separating plate, the packaging material is transferred one by one to the output end at a fixed time or speed to complete the bottle-separating action.

[0028] like Figure 4 and Figure 5 As shown, the labeling station 2 includes an unwinding shaft 22 and a rewinding shaft 23. The label on the unwinding shaft 22 is wound around multiple sets of tensioning shafts and wound around the rewinding shaft 23 from the label output plate 24. A brake shaft 25 is provided on the side of the unwinding shaft 22. In the working state, the label output plate is close to the label roller belt with a gap. The label on the surface of the label output plate first contacts the bottle body of the packaging material. After the end of the label is bonded to the bottle body, the packaging material moves to the right. Through the force of the label roller belt and the movable baffle, the label is bonded to the surface of the bottle body.

[0029] In practical use, the staff installs the label roll on the unwinding shaft, passes the beginning of the label roll through each tensioning shaft and the label output plate in sequence, and sets the second station as the labeling station. The spacing is adjusted according to the packaging material specifications using the spacing adjustment component. The lifting cylinder located in front of the second station controls the lowering of the lifting baffle. The cylinder slide rail module of the second station moves the labeling table toward the conveyor belt assembly. The linkage mechanism located on the far right of the transverse slide rail module moves toward the second station, so that the label output plate and the label roller belt maintain a certain distance. After the packaging material on the left side passes through the bottle separating mechanism and moves to the second station... Labeling is completed; when the label roll at the second station is exhausted, the adjusting motor at the bottle-separating mechanism adjusts its speed accordingly, the linkage mechanism resets to the right, the cylinder slide rail module at the second station moves backward, the lifting cylinder at the front of the first station controls the lifting baffle to descend, the cylinder slide rail module below the first station drives the labeling table forward to its position, the lateral slide rail module drives the linkage mechanism to move towards the first station, so that the label plate and the label belt maintain a certain distance. After it is in place, the lifting baffle at the front of the second station rises, the adjusting motor speed at the bottle-separating mechanism returns to normal, and labeling continues.

[0030] Several points need to be clarified: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly, and can refer to mechanical or electrical connections, or internal connections between two components, or direct connections. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships, and the relative positional relationships may change when the absolute position of the described objects changes. Second, in this document, relational terms such as "first" and "second" are only used to distinguish one entity from another entity, and do not necessarily require or imply any such actual relationship or order between these entities.

[0031] The examples above are merely illustrative of the present invention and do not constitute a limitation on the scope of protection of the present invention. All designs that are the same as or similar to the present invention are within the scope of protection of the present invention.
