Description

Technical Field

[0001] This utility model relates to the field of packaging anti-counterfeiting technology, specifically to a hopper structure suitable for continuous feeding of labeling machines. Background Technology

[0002] In the current labeling machine field, as the core equipment for realizing automated product labeling in production lines of many industries such as food, pharmaceuticals, daily chemicals, and electronics, its operational efficiency is directly related to the overall production rhythm and product circulation efficiency. However, there is a significant technical pain point in this field: the capacity of the label hopper is obviously limited. Existing hoppers cannot store enough labels to support long-term continuous production, which directly leads to the need for frequent manual labeling operations during the production process.

[0003] This high frequency of manual intervention brings multiple problems: On the one hand, companies need to assign dedicated personnel to continuously monitor the labeling machine and keep abreast of the remaining labels in the hopper to ensure timely replenishment before the labels run out. This not only increases labor costs, but also poses a risk of sudden production line shutdown due to the subjectivity and fatigue of manual monitoring. On the other hand, and more importantly, traditional labeling operations must be completed while the machine is stopped. Each shutdown disrupts the continuous operation of the production line, and the equipment needs an adjustment period from shutdown to restart and return to stable operation. This not only directly results in the loss of effective production time, but may also affect the labeling accuracy due to parameter fluctuations during the start-up and shutdown process, thereby increasing the product defect rate.

[0004] For modern production lines that pursue high speed and continuous operation, the frequent downtime caused by insufficient material hopper capacity has become a major bottleneck restricting the improvement of production efficiency. Although some solutions attempt to reduce the frequency of labeling by simply increasing the volume of the material hopper, this approach easily leads to new problems such as excessive equipment footprint and label conveying jams, which contradicts the industry's demand for compactness and high precision. Therefore, how to innovate and achieve non-stop material feeding function on the basis of breaking through the material hopper capacity limitation to reduce the frequency of labeling, thereby ensuring the continuity and efficiency of the production process, has become a technical problem that urgently needs to be solved in the labeling machine field. Its solution has important practical significance and application value for promoting the industry's technological upgrading and helping the manufacturing industry reduce costs and increase efficiency. Utility Model Content

[0005] The present invention aims to provide a hopper structure suitable for continuous feeding of labeling machines, so as to solve the problems of limited hopper capacity, frequent manual labeling, and the need to stop the machine in the prior art.

[0006] The embodiments of this utility model are implemented as follows:

[0007] This utility model embodiment provides a hopper structure suitable for continuous feeding of labeling machines, which includes a hopper assembly;

[0008] The aforementioned hopper assembly includes a first independent hopper, a second independent hopper, a third independent hopper, and a fourth independent hopper. The bottom of the first independent hopper, the second independent hopper, the third independent hopper, and the fourth independent hopper are provided with a turntable. The first independent hopper, the second independent hopper, the third independent hopper, and the fourth independent hopper are evenly fixed around the turntable. The bottom of the turntable is connected to a servo motor for driving the turntable to rotate.

[0009] In use, the aforementioned servo motor precisely drives the aforementioned turntable. The aforementioned first independent hopper, the aforementioned second independent hopper, the aforementioned third independent hopper, and the aforementioned fourth independent hopper are symmetrically distributed around the aforementioned turntable. During the production process, when the labels in the independent hopper at the loading station are about to run out, the aforementioned servo motor at the bottom starts. The servo motor drives the aforementioned turntable to rotate precisely 90 degrees. This rotation action cleverly moves the adjacent full independent hopper to the loading station, ensuring the continuity of label supply. At the same time, it moves the empty independent hopper to a specific position. At this time, the moved empty independent hopper can be refilled while the equipment is running, improving production efficiency.

[0010] The material hopper structure disclosed in this embodiment, suitable for continuous material feeding of labeling machines, uses a servo motor to drive the turntable to rotate. This causes the first, second, third, or fourth independent material hoppers, fully loaded with labels, to move to the feeding station, while empty independent material hoppers are moved to specific positions. This allows for refilling while the equipment is running, thus providing the beneficial effects of continuous material feeding for labeling machines, including non-stop feeding, ensuring production continuity and efficiency, reducing labor costs, ensuring accurate label dispensing, improving production efficiency, and promoting the development of labeling machine technology.

[0011] Optionally, a label transfer component is provided on one side of the aforementioned hopper assembly, and the label transfer component has an adsorption head, which corresponds to the aforementioned first independent hopper.

[0012] With this configuration, the adsorption head on the label transfer component is responsible for picking up the topmost label from the outlet of the first independent hopper and transferring and pasting the label onto the target carrier. The label picking is preferably done using a vacuum adsorption method.

[0013] Optionally, a lifting mechanism is provided on the other side of the aforementioned hopper assembly. The lifting mechanism has a lifting plate inside, and the lifting plate presses against the bottom of the label inside the first independent hopper.

[0014] With this configuration, the lifting plate can extend deep into the bottom of the first independent hopper to lift the label stack inside the first independent hopper, ensuring that the top label is always at an easily accessible height.

[0015] Optionally: The outlet of the first independent hopper is provided with several parallel brushes, and the brushes are connected to brush holders, which are fixedly connected to the top of the lifting mechanism.

[0016] With this setup, the aforementioned brushes ensure orderly label output. When a label is drawn into the discharge hopper, the brushes effectively prevent a second label from being carried out of the hopper, thus ensuring that only one label is released and transported to the labeling station at a time. This design detail not only improves the accuracy of label supply but also effectively avoids labeling errors and equipment jamming caused by multiple labels being discharged simultaneously, further enhancing the stability and reliability of the entire labeling process. In addition, the aforementioned brushes can also clean paper shavings and dust generated by die-cutting.

[0017] Optionally: The bottom end of the above-mentioned lifting mechanism is provided with a forward and reverse motor, the lifting plate is threaded with a reciprocating rod, both ends of the reciprocating rod are connected with bearing seats, and the output shaft of the forward and reverse motor is drivenly connected to the end of the reciprocating rod close to the forward and reverse motor.

[0018] With this configuration, when the aforementioned forward and reverse motors are activated, they drive the reciprocating rod on the bearing housing to rotate, allowing the lifting plate to perform lifting and lowering functions on the reciprocating rod, thereby facilitating the lifting of the label stack inside the first independent hopper.

[0019] Optionally, the lifting plate and the reciprocating rod are provided with a protective shell, the inner side of the protective shell is provided with a column, the bearing seat is fixed on the column, and the protective shell is detachably connected to the lifting mechanism.

[0020] With this configuration, the column provides the mounting base for the bearing housing, allowing the bearing housings at both ends of the reciprocating rod to restrict the position of the reciprocating rod, facilitating the lifting plate to move up and down along the axial direction of the reciprocating shaft. The protective shell protects the lifting plate and the reciprocating shaft, preventing them from wearing each other or the lubricating oil from splashing out and contaminating the label.

[0021] Optionally: The bottom of the column is provided with a base box, the column fixing bolts are connected to the base box, the forward and reverse motors are located at the bottom of the base box and are connected to the end of the reciprocating rod near the forward and reverse motors.

[0022] With this configuration, the base box facilitates the fixing and positioning of the column, and also facilitates the installation and fixing of the forward and reverse motors, enabling the forward and reverse motors to effectively drive the reciprocating rod to rotate, thereby controlling the up and down movement of the lifting plate.

[0023] Optionally: the outer ends of some of the above-mentioned brushes correspond to the long side of the label in the first independent hopper.

[0024] In order to avoid the label transfer component from adsorbing multiple labels at once, several brushes are installed at the outlet of the first independent hopper. When the adsorption head picks up the top label and removes it from the hopper, the brushes can effectively block and separate the labels that may stick below it, and remove paper scraps or dust generated by die cutting, thereby ensuring that only a single label is output each time.

[0025] Optionally: The bottom of the first independent hopper, the second independent hopper, the third independent hopper and the fourth independent hopper are equipped with a base plate, and the base plate is fixedly installed on the turntable;

[0026] The first independent silo, the second independent silo, the third independent silo, and the fourth independent silo all have a first side plate, a second side plate, a third side plate, and a fourth side plate that are spaced apart, and the first side plate, the second side plate, the third side plate, and the fourth side plate are arranged symmetrically to each other;

[0027] The first side plate, the second side plate, the third side plate and the fourth side plate have accommodating cavities in their internal axial direction, and several stacked labels are installed inside the accommodating cavities.

[0028] With this configuration, the first, second, third, and fourth independent material bins all share a single base plate. This base plate is used to fix the labels to the turntable and support them. The accommodating cavity formed by the first, second, third, and fourth side plates can accommodate several stacked labels. This effectively expands the bin capacity, avoids frequent manual label refilling, enables non-stop material refilling, ensures production continuity and efficiency, reduces labor costs, and improves production efficiency.

[0029] Optionally: the label transfer assembly has a base, a transverse guide rail is connected to the base, a slidable slide is clamped on the side of the transverse guide rail near the first independent hopper, a slider is slidably connected to the vertical direction of the slide, an adsorption seat is bolted to the bottom end of the slider, and the adsorption head is fixedly installed on the adsorption seat and located on the side near the first independent hopper.

[0030] With this configuration, the label transfer assembly is supported by the base, the slide slides on the guide rail, and the slider on the slide carries the adsorption seat to slide vertically along the slide, thereby facilitating the adsorption head to pick up the top label and transfer it to the target carrier.

[0031] In summary, the material hopper structure disclosed in this utility model for continuous material feeding of labeling machines has the beneficial effects of enabling continuous material feeding without stopping the machine, ensuring production continuity and efficiency, reducing labor costs, ensuring accurate labeling, improving production efficiency, and promoting the development of labeling machine technology.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] Example

[0040] See Figure 1 , Figure 2 and Figure 3 This embodiment proposes a hopper structure suitable for continuous feeding of labeling machines, including hopper component 1;

[0041] The hopper assembly 1 has a first independent hopper 2, a second independent hopper 3, a third independent hopper 4, and a fourth independent hopper 5. The bottom of the first independent hopper 2, the second independent hopper 3, the third independent hopper 4, and the fourth independent hopper 5 are provided with a turntable 6. The first independent hopper 2, the second independent hopper 3, the third independent hopper 4, and the fourth independent hopper 5 are evenly fixed around the turntable 6. The bottom of the turntable 6 is connected to a servo motor 7 for driving the turntable 6 to rotate.

[0042] In use, the servo motor 7 precisely drives the turntable 6. The turntable 6 is symmetrically distributed with the first independent hopper 2, the second independent hopper 3, the third independent hopper 4, and the fourth independent hopper 5. During production, when the labels 26 in the independent hopper at the loading station are about to run out, the bottom servo motor 7 starts and drives the turntable 6 to rotate precisely 90 degrees. This rotation cleverly moves the adjacent full independent hopper to the loading station, ensuring the continuity of label 26 supply. At the same time, it moves the empty independent hopper to a specific position. At this time, the moved empty independent hopper can be refilled while the equipment is running, improving production efficiency.

[0043] The hopper structure disclosed in this embodiment, suitable for continuous material feeding of labeling machines, uses a servo motor 7 to drive the turntable 6 to rotate. This causes the first independent hopper 2, the second independent hopper 3, the third independent hopper 4, or the fourth independent hopper 5, which is fully loaded with labels 26, to move to the feeding station. Empty independent hoppers are moved to specific positions so that the equipment can be refilled while it is running. This hopper structure, suitable for continuous material feeding of labeling machines, achieves continuous material feeding without stopping the machine, ensures production continuity and efficiency, reduces labor costs, ensures accurate label dispensing, improves production efficiency, and promotes the development of labeling machine technology.

[0044] See Figure 1 , Figure 2 and Figure 3 A label transfer component 8 is provided on one side of the hopper component 1. The label transfer component 8 has an adsorption head 9, which corresponds to the first independent hopper 2. The adsorption head 9 on the label transfer component 8 is responsible for picking up the topmost label 26 from the hopper outlet of the first independent hopper 2 and transferring the label 26 to the target carrier. The label 26 is preferably picked up by vacuum adsorption (other equivalent methods can also be used).

[0045] On the other side of the hopper assembly 1, there is a lifting mechanism 10. Inside the lifting mechanism 10, there is a lifting plate 11. The lifting plate 11 presses against the bottom of the label 26 inside the first independent hopper 2. The lifting plate 11 can penetrate into the bottom of the hopper of the first independent hopper 2 to lift the stack of labels 26 inside the first independent hopper 2, ensuring that the top label 26 is always at an easily accessible height.

[0046] The outlet of the first independent hopper 2 is equipped with several parallel brushes 12, each brush 12 connected to a brush holder 13. The brush holder 13 is fixedly connected to the top of the lifting mechanism 10. The brushes 12 ensure that the labels 26 are discharged in an orderly manner. When a label 26 is sucked into the outlet of the hopper, the brushes 12 can effectively prevent a second label from being carried out of the hopper, thus ensuring that only one label is released and transmitted to the labeling station at a time. This design detail not only improves the accuracy of label 26 supply, but also effectively avoids labeling errors and equipment jamming caused by multiple labels 26 being discharged at the same time, further improving the stability and reliability of the entire labeling process. At the same time, the brushes 12 can also clean the paper scraps and dust generated by die-cutting of the labels 26.

[0047] See Figure 1 , Figure 2 and Figure 3The bottom of the lifting mechanism 10 is equipped with a forward and reverse motor 14. A reciprocating rod 15 is threaded onto the lifting plate 11. Both ends of the reciprocating rod 15 are connected to bearing seats 16. The output shaft of the forward and reverse motor 14 is driven to the end of the reciprocating rod 15 near the forward and reverse motor 14. When the forward and reverse motor 14 is started, it drives the reciprocating rod 15 on the bearing seat 16 to rotate, so that the lifting plate 11 can achieve the lifting function on the reciprocating rod 15, thereby facilitating the lifting of the label 26 stack inside the first independent hopper 2.

[0048] The lifting plate 11 and the reciprocating rod 15 are provided with a protective shell 17. The inner side of the protective shell 17 is provided with a column 18. The bearing seat 16 is fixed on the column 18. The protective shell 17 is detachably connected to the lifting mechanism 10. The column 18 provides a mounting base for the bearing seat 16, so that the bearing seats 16 at both ends of the reciprocating rod 15 can restrict the position of the reciprocating rod 15, which facilitates the lifting plate 11 to move up and down along the axial direction of the reciprocating shaft. The protective shell 17 can protect the lifting plate 11 and the reciprocating shaft, prevent them from wearing each other or the lubricating oil from splashing out, and prevent the label 26 from being contaminated.

[0049] The bottom of the column 18 is provided with a base box 19. The column 18 is fixed and bolted inside the base box 19. The forward and reverse motor 14 is located at the bottom of the base box 19 and is connected to the reciprocating rod 15 near the end of the forward and reverse motor 14. The base box 19 facilitates the fixing and limiting of the column 18, and also facilitates the installation and fixing of the forward and reverse motor 14, so that the forward and reverse motor 14 can drive the reciprocating rod 15 to rotate well, thereby controlling the lifting plate 11 to move up and down.

[0050] The outer ends of several brushes 12 correspond to the long side of the label 26 in the first independent hopper 2. To prevent the label transfer component 8 from adsorbing multiple labels at once, several brushes 12 are set at the outlet of the first independent hopper 2. When the adsorption head 9 picks up the top label 26 and removes it from the hopper, the several brushes 12 can effectively block and separate the labels 26 that may stick below it, and remove paper scraps or dust generated by die cutting, thereby ensuring that only a single label 26 is output each time.

[0051] See Figure 1 , Figure 2 and Figure 3The bottom of the first independent silo 2, the second independent silo 3, the third independent silo 4, and the fourth independent silo 5 is equipped with a base plate 20, which is fixedly mounted on the turntable 6. Each of the first independent silo 2, the second independent silo 3, the third independent silo 4, and the fourth independent silo 5 has a first side plate 21, a second side plate 22, a third side plate 23, and a fourth side plate 24 spaced apart, symmetrically arranged. The internal axial direction of the first side plate 21, the second side plate 22, the third side plate 23, and the fourth side plate 24 has… The accommodating cavity 25 contains several stacked labels 26. The first independent hopper 2, the second independent hopper 3, the third independent hopper 4, and the fourth independent hopper 5 all share a base plate 20, which is used to fix the turntable 6 and support the labels 26. The accommodating cavity 25, formed by the first side plate 21, the second side plate 22, the third side plate 23, and the fourth side plate 24, can accommodate several stacked labels 26. This effectively expands the hopper capacity, avoids frequent manual label addition, achieves non-stop material addition, ensures production continuity and efficiency, reduces labor costs, and improves production efficiency.

[0052] The label transfer assembly 8 has a base 27, on which a horizontal guide rail 28 is connected. The side of the horizontal guide rail 28 near the first independent hopper 2 holds a slidable slide 29. A slider 30 is slidably connected to the vertical direction of the slide 29. An adsorption seat 31 is bolted to the bottom end of the slider 30. The adsorption head 9 is fixedly installed on the adsorption seat 31 and located on the side near the first independent hopper 2. The label transfer assembly 8 is supported by the base 27. The slide 29 slides on the guide rail. The slider 30 on the slide 29 carries the adsorption seat 31 and slides vertically along the slide 29, which facilitates the adsorption head 9 to pick up the top label 26 and transfer it to the target carrier.

[0053] See Figure 1 , Figure 2 and Figure 3 In this embodiment, there is a through gap 32 between the first side plate 21 and the second side plate 22. The lifting plate 11 has a lifting end 33 at one end near the first independent hopper 2, the second independent hopper 3, the third independent hopper 4, or the fourth independent hopper 5. The lifting end 33 slides along the through gap 32, and the lifting plate 11 can penetrate deep into the bottom of the hopper. When the lifting plate 11 rises, the lifting end 33 slides into the through gap 32, which facilitates lifting the stack of labels 26 in the hopper and ensures that the top label 26 is always at an easy-to-pick-up height.

[0054] In this embodiment, each time the first independent hopper 2, the second independent hopper 3, the third independent hopper 4, and the fourth independent hopper 5 rotate, the lifting plate 11 will first descend to the bottom of the turntable 6. When the new independent hopper fully loaded with labels 26 rotates and moves to the loading station, the lifting plate 11 rises, and the lifting end 33 on the lifting plate 11 will slide into the through slot 32 of the new independent hopper to facilitate the lifting of the labels 26 in the hopper for stacking, so that the top layer of labels 26 is always at an easily accessible height.

[0055] See Figure 1 , Figure 2 and Figure 3 In this embodiment, the hopper structure mainly includes a label transfer component 8, a turntable 6, a hopper component 1, and a lifting mechanism 10. The hopper component 1 includes a first independent hopper 2, a second independent hopper 3, a third independent hopper 4, and a fourth independent hopper 5. The four independent hoppers are evenly distributed and fixed around the turntable 6. Labels 26 are stacked in each independent hopper. The servo motor 7 drives the turntable 6 to rotate, enabling the switching of the four independent hoppers. The lifting mechanism 10 is located below the current working hopper, and its lifting plate 11 can penetrate deep into the bottom of the hopper to lift the stack of labels 26 in the hopper, ensuring that the top label 26 is always at an easily accessible height. The label transfer component 8 is responsible for picking up the top label 26 from the working hopper and transferring and pasting it onto the target carrier. The label 26 is preferably picked up using a vacuum adsorption method (other equivalent methods can also be used). This solution effectively solves the downtime problem caused by frequent manual feeding in the prior art by configuring four independent hoppers and the turntable 6, and significantly improves production efficiency.

[0056] See Figure 1 , Figure 2 and Figure 3 The specific operating principle of the hopper structure applicable to the uninterrupted feeding of the labeling machine in this embodiment is as follows:

[0057] First, a four-station rotary design is adopted, including a turntable 6 precisely driven by a servo motor 7. The turntable 6 is symmetrically distributed with a first independent hopper 2, a second independent hopper 3, a third independent hopper 4, and a fourth independent hopper 5. This design enables efficient switching of hoppers and ensures the continuity of label supply during production. When the labels 26 in the first independent hopper 2 at the loading station are about to run out, the lifting mechanism 10 drives its lifting plate 11 to descend below the turntable 6. The servo motor 7 starts and drives the turntable 6 to rotate 90 degrees clockwise, moving the adjacent second independent hopper 3 to the loading station. At the same time, the empty first independent hopper 2 is moved to a specific position. The moved first independent hopper 2 can then be refilled while the equipment is running continuously, which significantly improves production efficiency and reduces downtime.

[0058] Secondly, the lifting mechanism 10 rises, and its lifting plate 11 extends into the bottom of the second independent hopper 3 again, lifting the stack of labels 26;

[0059] Finally, to prevent the label transfer component 8 from adsorbing multiple labels at once, several brushes 12 are added at the hopper opening above the feeding station. When the adsorption head 9 picks up the top label 26 and removes it from the hopper, the brushes 12 can effectively prevent the second label from being carried out of the hopper, ensuring that only one label is released and transferred to the labeling station at a time. This design improves the accuracy of label 26 supply and avoids labeling errors and equipment jamming caused by multiple labels 26 being discharged at the same time. The brushes 12 can also clean the paper scraps and dust generated by die-cutting of the labels 26, further improving the quality of the labels 26 and the labeling effect.

[0060] See Figure 1 , Figure 2 and Figure 3 The beneficial effects of this embodiment are as follows:

[0061] 1. High-efficiency material change without stopping the machine: The machine adopts a four-station independent material bin design with the first independent material bin 2, the second independent material bin 3, the third independent material bin 4 and the fourth independent material bin 5 rotating. When the labels 26 at the feeding station are exhausted, the servo motor 7 drives the turntable 6 to rotate 90 degrees, quickly switching the material bins to ensure uninterrupted supply of labels 26. At the same time, the empty material bins can be refilled while the equipment is running, which greatly improves production efficiency.

[0062] 2. Reduce labor costs: By expanding the capacity of independent silos and enabling non-stop material feeding, the frequency of material feeding by workers is significantly reduced, and the reliance on manual supervision is reduced, thereby saving labor costs.

[0063] 3. Precise label dispensing control: A brush 12 is added to the material hopper at the feeding station to effectively prevent the second label 26 from being carried out, ensuring that only one label 26 is dispensed at a time, providing precise supply, avoiding labeling errors and equipment jamming, and ensuring the stability of the labeling process.

[0064] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
