Description

Technical Field

[0001] The present application relates to the technical field of labeling equipment, and in particular to a label feeding device and a labeling machine. Background Art

[0002] A labeling machine is a device that uses adhesive to stick paper or metal foil labels on specified packaging containers. When the sensor sends a signal that the object to be labeled is ready for labeling, the drive wheel on the labeling machine rotates. Since the roll label is in a tensioned state on the device, when the base paper is close to the peeling plate and changes direction, the label has a certain degree of stiffness, and the front end is forced to detach and prepare for labeling. At this time, the object to be labeled is just under the label, and synchronous labeling is achieved under the action of the labeling wheel. After labeling, the sensor under the roll label sends a signal to stop running, the drive wheel stops, and a labeling cycle ends.

[0003] In the labeling machine, the label feeding device works with the labeling head, and is mainly used to feed labels to the labeling head. It is an important part of the labeling machine. However, in the related art, the label feeding device usually only has the function of feeding the label paper with information printed on it to the labeling head one by one. When the production line changes other products to be labeled, the label roll also needs to be replaced synchronously. The replacement operation is time-consuming and labor-intensive, and the whole machine needs to be shut down when replacing the label roll, which affects the production efficiency. In addition, the structural layout of the functional modules of the existing label feeding equipment is unreasonable, and it occupies a large installation space. Summary of the invention

[0004] Based on this, it is necessary to provide a label feeding device and a labeling machine to address the problems that the replacement operation is time-consuming and labor-intensive, affects production efficiency, and has an unreasonable structural layout.

[0010] In the label delivery equipment of the present scheme, the label supply mechanism, printing mechanism, detection mechanism and label output arm are arranged in sequence according to the upstream and downstream. The structural layout is reasonable and compact, and the space occupied is small. When working, the driving component drives the label supply component to rotate, so as to drive the temporarily stored label roll to rotate together to realize the continuous delivery of label paper. The delivered label paper then enters the printing station, and the printing mechanism prints the required label information on the label paper online in real time. Even when the product on the production line changes and causes the label information to change, it only needs to input the new label information into the printing mechanism, so that the printed label paper can meet the current product needs, without replacing the label roll, saving time and labor, and without stopping the production line, ensuring production efficiency; further, the printed label paper enters the detection mechanism, and the detection mechanism detects the integrity of the label information. Finally, the label paper that meets the quality requirements arrives at the label output arm, and the label output arm conveys the label paper to the labeling station.

[0033] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0034] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0035] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0036] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0037] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0039] See also Figure 1 and Figure 2 , which is a label delivery device shown in an embodiment of the present application, includes a label supply mechanism 10, a printing mechanism 20, a detection mechanism 30, and a label output swinging arm 40. In addition, the label delivery device may also include a mounting seat, which is used to load and integrate the label supply mechanism 10, the printing mechanism 20, the detection mechanism 30, and the label output swinging arm 40, so as to improve the integration degree and structural compactness of the label delivery device.

[0040] Of course, the label delivery device can also omit the mounting base, and instead directly install the label supply mechanism 10, the printing mechanism 20, the detection mechanism 30 and the label output swing arm 40 on the base of the labeling machine to save the mounting base, simplify the overall structure and reduce manufacturing costs; the specific implementation method can be flexibly selected according to actual needs.

[0041] In the present application, the label supply mechanism 10 includes a driving component 11 and a label supply component 12. The driving component 11 is connected to the label supply component 12 to drive the label supply component 12 to rotate. The label supply component 12 is used to temporarily store the label roll and transport the label paper outward.

[0042] It is necessary to explain that the label roll actually includes a roll and label paper, and the label paper is installed on the outer circumference of the roll in a winding manner to increase the label paper receiving capacity of a single roll of label.

[0043] The label paper has a double-layer structure, that is, it is composed of an upper layer of surface paper and a lower layer of bottom paper. The bottom surface of the surface paper is provided with an adhesive layer, which is set on the bottom paper by bonding. The surface paper of the label paper actually needs to be pasted on the product, and the bottom paper needs to be recycled, that is, the printing mechanism 20 needs to print the label information on the surface paper. The bottom paper collection mechanism 50 will be introduced below and then described in detail.

[0044] It is understandable that the label information printed on the facial paper includes but is not limited to the brand logo, ingredient list, production date, manufacturer, shelf life, etc.

[0045] In the present application, the printing mechanism 20 is arranged downstream of the label supply mechanism 10, and the printing mechanism 20 is used to print label information on the label paper transmitted to the printing station; the detection mechanism 30 is arranged downstream of the printing mechanism 20, and the detection mechanism 30 is used to detect the integrity of the label information printed on the label paper; the label waving arm 40 is arranged downstream of the detection mechanism 30, and the label waving arm 40 is used to transmit the label paper to the labeling station.

[0046] In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: in the label delivery device of this solution, the label supply mechanism 10, the printing mechanism 20, the detection mechanism 30 and the label output swing arm 40 are arranged in sequence in the upstream and downstream, the structural layout is reasonable and compact, and the space occupied is small. When working, the driving component 11 drives the label supply component 12 to rotate, so as to drive the temporarily stored label roll to rotate together to realize the continuous delivery of the label paper, and the delivered label paper then enters the printing station, and the printing mechanism 20 prints the required label information on the label paper online, and even when the product on the production line changes and causes the label information to change, it only needs to input the new label information into the printing mechanism 20, so that the printed label paper can meet the current product needs, without replacing the label roll, saving time and effort, and without stopping the production line, ensuring production efficiency; further, the printed label paper enters the detection mechanism 30, and the detection mechanism 30 detects the integrity of the label information. Finally, the label paper that meets the quality requirements arrives at the label output swing arm 40, and the label output swing arm 40 conveys the label paper to the labeling station.

[0047] In addition, the functional components such as the signature supply mechanism 10, printing mechanism 20, detection mechanism 30, and label issuing arm 40 in the present application can also adopt a modular design, and each module can be flexibly combined according to the needs of different users to enable the label delivery equipment to have different functions and meet diverse usage needs.

[0048] Please continue reading Figure 1 and Figure 2 In some optional embodiments, the driving assembly 11 includes a driver and a transmission assembly for transmitting rotational power, the driver is connected to the transmission assembly, the label supply assembly 12 includes a first tray 121 and a first receiving shaft 122, the first receiving shaft 122 is arranged on the first tray 121, and the first tray 121 is connected to the transmission assembly; wherein, the first receiving shaft 122 is used to set the label roll.

[0049] When the label delivery device delivers labels to products, the driver outputs power and transmits the rotational power to the first tray 121 through the transmission assembly, thereby driving the first tray 121 to rotate in the horizontal plane, and the first tray 121 drives the first receiving shaft 122 to rotate synchronously, so that the label roll installed on the first receiving shaft 122 can continuously roll out the label paper. Since multiple surface papers are continuously arranged on the base paper of the label paper, each surface paper passes through the printing mechanism 20 one by one and finally reaches the labeling station, meeting the processing needs of continuous labeling of each product.

[0050] Furthermore, in one embodiment, the first receiving shaft 122 includes a main shaft body 122a and a tensioning unit, and the tensioning unit can be movably arranged on the main shaft body 122a to make the diameter of the first receiving shaft 122 adjustable. In the initial state, the tensioning unit maintains a contraction structure, so that the diameter of the first receiving shaft 122 is the smallest and smaller than the inner diameter of the roll, so as to facilitate the label roll to be installed on the outside of the first receiving shaft 122, reducing the difficulty of label roll installation; when the label roll is installed on the outside of the first receiving shaft 122, the tensioning unit is operated to switch to the expansion structure, at which time the diameter of the first receiving shaft 122 increases, and the tensioning unit presses against the inner wall of the roll to fix the label roll, ensuring that the label roll can rotate synchronously with the first receiving shaft 122, and ensuring that the label paper can be continuously rolled out.

[0051] The expansion unit adopts a mature expansion structure in the prior art, such as any one of a pneumatic expansion shaft and a mechanical expansion shaft, so it will not be described in detail here.

[0052] Alternatively, in another embodiment, the first receiving shaft includes a main shaft body 122a and a tensioning unit, the tensioning unit is formed by connecting an elastic body 122b and a tensioning plate 122c, preferably the elastic body 122b and the tensioning plate 122c are both provided in a plurality and are assembled into a plurality of tensioning units in a one-to-one correspondence, the plurality of tensioning units are arranged equidistantly along the outer circumference direction of the main shaft body 122a, each tensioning plate 122c extends from an inlet and outlet opened on the main shaft body 122a to the outside of the main shaft body 122a, and is supported and fixed by the elastic body 122b. When the label roll is sleeved onto the outside of the main shaft body 122a, the tensioning plate 122c is pushed to move inside the main shaft body 122a and thus compress the elastic body 122b to deform, the elastic body 122b applies an elastic thrust to the tensioning plate 122c, so that the tensioning plate 122c can press the inner wall of the roll of the label roll, thereby achieving adaptive tensioning and fixing of the label roll. The label roll is stably supported to prevent slipping, the label roll installation and removal method is simple and the feasibility is strong.

[0053] Alternatively, the elastic body 122b may be a rubber block or the like.

[0054] Please continue reading Figure 1 and Figure 2 In addition, based on the above embodiment, the label feeding device also includes a base paper collecting mechanism 50, which is arranged downstream of the label feeding mechanism 10. The base paper collecting mechanism 50 includes a driving unit 51, a second tray 52 and a second receiving shaft 53. The driving unit 51 is connected to the second tray 52 to drive the second tray 52 to rotate. The second receiving shaft 53 is arranged on the second tray 52 and is used to roll up the base paper.

[0055] When the surface paper of the label paper is continuously fed to the labeling station, the driving unit 51 drives the second tray 52 and the second receiving shaft 53 to rotate synchronously, so that the second receiving shaft 53 can continuously wind up and recycle the bottom paper separated from the surface paper to avoid the bottom paper being scattered around in a disorderly manner, thereby facilitating the centralized recycling of the bottom paper.

[0056] As the processing continues, the amount of bottom paper recovered onto the second receiving shaft 53 continues to increase, which is intuitively manifested in that the diameter of the bottom paper roll continues to increase, and the corresponding weight also continues to increase. In order to facilitate the staff to smoothly remove the bottom paper roll from the second receiving shaft 53 after the production is completed, in some optional embodiments, the outer peripheral edge of the second tray 52 is concave inward toward the center of the tray to form at least one avoidance recess 521. When the diameter of the bottom paper roll increases to a certain value, the bottom surface of the bottom paper roll extends above the avoidance recess 521, so that the fingers of the staff can move from the bottom to the top through the avoidance recess 521 to lift the bottom paper roll, and then lift it upward, so that the bottom paper roll can be quickly and conveniently removed from the second receiving shaft 53.

[0057] Furthermore, the bottom paper collecting mechanism 50 further includes a detection electric eye 54, which is mounted on the driving unit 51 through a bracket, and a detection portion of the detection electric eye 54 is used to be arranged opposite to the bottom paper roll on the second tray 52. ​​When the number of bottom paper rolls recovered on the second receiving shaft 53 reaches a preset value, the detection electric eye 54 will be triggered and then feedback a detection signal to the driving unit 51, the driving unit 51 stops outputting power, and the second receiving shaft 53 stops rotating, so that the bottom paper roll can be removed in time.

[0058] For example, the detection electric eye 54 is a laser sensor, and the laser round-trip time of the laser sensor is set to t1. In the initial stage, the amount of base paper wound on the second receiving shaft 53 is small, and the diameter of the corresponding base paper roll is also small. The time taken for the laser to irradiate the outermost layer of the base paper roll and then return to the laser sensor is long (i.e., greater than t1); but as the amount of base paper wound increases, the diameter of the base paper roll continues to increase, and the laser round-trip time continues to decrease. At a certain moment, when the actual round-trip time t2 is equal to the set round-trip time t1, the laser sensor will be triggered.

[0059] In addition, based on any of the above embodiments, the printing mechanism 20 includes a printing bracket, a printer 21 and a controller, the printing bracket is provided with a printing window, the printer 21 is arranged on the printing bracket, and the printing execution part of the printer 21 is opposite to the printing window, and the printer 21 is electrically connected to the controller.

[0060] It is necessary to explain that a circulation channel is planned in the label delivery equipment, and the face paper of the label paper goes along the circulation channel from the label supply mechanism 10, the printing mechanism 20, the detection mechanism 30 and finally reaches the label output hand 40. When the face paper reaches the printing station, that is, when the face paper is facing the printing window and the printing execution part, the label supply mechanism 10 and the bottom paper receiving mechanism 50 will both stop for a short period of time. This period of time corresponds to the printing time consumed by the printing execution part to print the label information on the face paper. When the printing execution part completes the printing of the label information on the face paper through the printing window, the face paper will continue to be transmitted to the detection mechanism 30. The main purpose of setting up the controller is to facilitate the operator to input the corresponding label information into the controller according to the different products replaced on the production line. The controller then sends the different label information to the printer 21 in the form of instructions, so that the printer 21 has the ability to flexibly change the label information to meet the online change of label information, saving the time and effort required to replace different label rolls.

[0061] Optionally, the printer 21 can be any one of a laser printer 21, a foam printer 21, etc., and the selection can be made according to actual needs.

[0062] In the above embodiment, the printing bracket includes a fixed main bracket 22, and an inspection bracket 23 rotatably arranged on the main bracket 22 through a rotating shaft. The main bracket 22 is provided with a printing window. The main bracket 22 and the inspection bracket 23 cooperate to form an installation cavity, and the printer 21 is arranged in the installation cavity.

[0063] The printing bracket also includes a connecting rod 24 and a connecting sleeve. One end of the connecting rod 24 is fixed on the main bracket 22, and the connecting sleeve is arranged on the maintenance bracket 23. The maintenance bracket 23 has a closed position and an open position. When the maintenance bracket 23 is in the closed position, the end of the connecting rod 24 away from the main bracket 22 is plugged into the connecting sleeve. When the maintenance bracket 23 is in the open position, the connecting rod 24 is separated from the connecting sleeve, and the maintenance bracket 23 flips downward and away from the printer 21.

[0064] It is easy to understand that the printing bracket is designed to be a main bracket 22 and an inspection bracket 23 that are movably connected. When the inspection bracket 23 is in a closed position, the inspection bracket 23 can cooperate with the main bracket 22 to clamp and fix the printer 21 placed in the installation cavity, thereby ensuring that the printer 21 is firmly installed; when the printer 21 needs to be cleaned and maintained regularly or the printer 21 is damaged and needs repair, the connecting rod 24 and the connecting sleeve are separated, and then the inspection bracket 23 is flipped downward to expose the ports and other parts on the back of the printer 21, thereby facilitating the inspection and maintenance of the printer 21 and improving the convenience and experience of the inspection and protection work.

[0065] In some embodiments, the detection mechanism 30 includes a detection bracket and a detection camera, and the detection camera is arranged on the detection bracket. The detection camera is specifically a visual detection camera, which can obtain image data of the label information printed on the surface paper by shooting the whole picture of the surface paper, and can judge the label printing quality by analyzing the completeness and clarity of the label information, so as to avoid defective label surface paper being pasted on the product and affecting the finished product quality of the product.

[0066] The label waving arm 40 has a roller assembly 43, which can be rotatably installed on the main machine through the roller assembly 43 and has a greater angle adjustment capability. The main components of the label waving arm 40 include but are not limited to a label guide rod 41, a peeling plate 42, etc., which can accurately transfer the label surface paper to the product labeling position.

[0067] In addition to the above, the present application also provides a labeling machine, which includes a label delivery device as described in any of the above embodiments.

[0068] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
