Referring to fig. 2, in the embodiment, the first frame body 10 further includes a first frame 11, a sliding rail 12 transversely disposed on the first frame 11, and a first connecting plate 13 slidably disposed on the sliding rail 12, the label peeling mechanism 30 and the labeling device 20 are respectively fixed on the first connecting plate 13, a horizontal distance between the label peeling mechanism 30 and the labeling device 20 is kept unchanged, and when a label peeled by the label peeling mechanism 30 is required to be adsorbed by the labeling assembly 22, only a vertical position of the labeling assembly 22 needs to be changed, and a horizontal position of the labeling assembly 22 does not need to be changed. The first frame 10 further comprises a first driving motor 14, wherein the first driving motor 14 is used as a power source for driving the first connecting plate 13 to horizontally slide on the slide rail 12, so that the label peeling mechanism 30 and the labeling device 20 fixed on the first connecting plate 13 horizontally move.

Referring to fig. 3, in the embodiment, the labeling device 20 further includes a driving mechanism 21, the labeling assembly 22 is disposed at one end of the driving mechanism 21, and the labeling assembly 22 can be lifted and lowered under the driving of the driving mechanism 21, so as to label objects with different height specifications.

Referring to fig. 4, the driving mechanism 21 includes a first lifting assembly 211 and a second lifting assembly 212, the first lifting assembly 211 includes a sliding seat 2111 and a sliding table 2112 slidably disposed on the sliding seat 2111, the second lifting assembly 212 is disposed on the sliding table 2112, the labeling assembly 22 is disposed at one end of the second lifting assembly 212, the first lifting assembly 211 further includes a second driving motor 2113, and the second driving motor 2113 serves as a power source for driving the first lifting assembly 211 to lift. In this application, first lifting unit 211 realizes going up and down for the slip of slide 2111 through slip table 2112, second lifting unit 212 itself can go up and down, and simultaneously, second lifting unit 212 sets up in first lifting unit 211's slip table 2112 again, the collocation of first lifting unit 211 and second lifting unit 212 can make actuating mechanism 21 realize two sections lifts, makes actuating mechanism 21 obtain bigger stroke, thereby make set up and paste mark subassembly 22 in second lifting unit 212 one end and obtain bigger workspace in vertical direction.

It should be noted that the labeling device 20 can be applied to labeling operation of objects (such as parcels or express) in the logistics industry, and the traditional labeling machine 1 can only be applied to parcels with fixed specifications due to different specifications and sizes of the parcels, which results in poor universality of the existing labeling machine 1. In the labeling device 20 of the present application, the driving mechanism 21 has two sections of lifting displacements, which can be adjusted according to the specification of the package, so as to improve the versatility of the labeling device 20.

Referring to fig. 4, in the embodiment, the second lifting assembly 212 includes a cylinder 2121 and a driving rod 2122 having one end movably connected to the cylinder 2121, and the other end of the driving rod 2122 is fixedly connected to the labeling assembly 22. When the second driving assembly drives the transmission rod 2122 to ascend and descend through the air cylinder 2121, the labeling assembly 22 ascends and descends along with the air cylinder 2121, and the air source of the air cylinder 2121 can be externally arranged on the labeling device 20, so that the second driving assembly not only has the advantages of quick action, quick response and the like in effect, but also has the advantages of simple structure, light weight and the like in structure.

It is worth mentioning that the movement between the first lifting assembly 211 and the second lifting assembly 212 is independent, and in operation, the first lifting assembly 211 and/or the second lifting assembly 212 can be selected to operate according to requirements. Specifically, when the package is moved to the position below the labeling assembly 22, and the lifting displacement of any one of the first lifting assembly 211 and the second lifting assembly 212 can satisfy the requirement of attaching the label to the package, one of the first lifting assembly 211 and the second lifting assembly 212 can be selected to be lifted, so as to save energy. Considering that the first lifting assembly 211 can actively control the stroke of the sliding table 2112 under the driving of the second driving motor 2113, and the driving device of the second lifting assembly 212 is the air cylinder 2121, the general air cylinder 2121 cannot actively control the stroke of the driving rod 2122, the specially-made air cylinder 2121 increases the cost, and therefore, when the lifting displacement of either one of the first lifting assembly 211 and the second lifting assembly 212 can meet the requirement of attaching a label to a package, the first lifting assembly 211 is preferably selected. When the parcel moves to labeling component 22 below, the lifting displacement of any one of first lifting component 211 and second lifting component 212 is less than the minimum distance from labeling component 22 to the parcel, and then both need to lift simultaneously or successively to achieve the purpose of labeling. In the cooperative working mode of ascending and descending successively, the ascending and descending orders of the two are not limited herein.

Referring to fig. 4, in this embodiment, the second lifting assembly 212 further includes a flange connection seat 2123 and a second connection plate 2124, the flange connection seat 2123 is fixedly disposed on the sliding table 2112, the cylinder 2121 is fixed to the flange connection seat 2123, one end of the transmission rod 2122 penetrates through the flange connection seat 2123 and is movably connected to the cylinder 2121, the other end of the transmission rod is fixedly disposed on one side of the second connection plate 2124, and the labeling assembly 22 is fixedly disposed on the other side of the second connection plate 2124, so that the connection strength between the first lifting assembly 211 and the second lifting assembly 212, and between the second lifting assembly 212 and the labeling assembly 22 can be ensured, and the mounting and dismounting are also facilitated.

Referring to fig. 4, in this embodiment, second lifting assembly 212 further includes a guide 2125, guide 2125 movably penetrates flange connection seat 2123 and is disposed parallel to transmission rod 2122, and a lower end of guide 2125 is fixedly connected to second connection plate 2124, when second lifting assembly 212 drives labeling assembly 22 to lift, guide 2125 is lifted along a matching surface of flange connection seat 2123, so that guide 2125 plays a role in guiding when second lifting assembly 212 drives labeling assembly 22, thereby ensuring a smooth process of driving labeling assembly 22 by second lifting assembly 212.

The lower end of the guide 2125 may be fixedly connected to the second connecting plate 2124 directly or via an intermediate member to the second connecting plate 2124.

Preferably, in order to make guide 2125 perform better guiding function, guide 2125 in the embodiment shown in fig. 4 is not directly movably connected to flange connecting seat 2123, but is slidably connected to guide barrel 2126 fixed to flange connecting seat 2123, and compared to directly slidably connecting guide 2125 to flange connecting seat 2123, the matching surface of guide 2125 slidably connected to guide barrel 2126 is longer to perform better guiding function, so that second lifting assembly 212 can drive labelling assembly 22 more smoothly. It should be noted that guiding cylinder 2126 may be disposed on an upper end surface of flange connecting seat 2123 (i.e. an end surface facing away from labeling assembly 22), or disposed on a lower end surface of flange connecting seat 2123 (i.e. an end surface facing toward labeling assembly 22) to better perform the guiding function. Of course, the guiding barrel 2126 can be disposed on the upper end surface and the lower end surface of the flange connecting seat 2123 at the same time, and the two are communicated with each other to better perform the guiding function.

Further, in the embodiment shown in fig. 4, two guiding elements 2125 are included, two guiding elements 2125 are symmetrically disposed on two sides of driving rod 2122, and correspondingly, two guiding barrels 2126 are also included, two guiding barrels 2126 are fixedly disposed on flange connecting seat 2123 and slidably connected to two guiding elements 2125, respectively, and when second lifting assembly 212 drives labeling assembly 22 to lift, two guiding elements 2125 respectively lift along the matching surfaces of guiding barrels 2126, so as to further improve the smoothness of the process of driving labeling assembly 22 by second lifting assembly 212.

Labelling assembly 22 comprises suction cup 221 and first elastic member 222, first elastic member 222 being located between suction cup 221 and second connecting plate 2124, in particular first elastic member 222 being fixed at one end to suction cup 221 and at the other end to second connecting plate 2124, so that suction cup 221 is movable with respect to second connecting plate 2124, e.g. first elastic member 222 is compressed, suction cup 221 being close towards second connecting plate 2124 to provide a certain cushioning effect and to allow suction cup 221 to be in sufficient contact with the article. On the other hand, due to the characteristics of the first elastic member 222, when the suction cup 221 is pressed on the object under the driving of the driving mechanism 21, if the working surface of the suction cup 221 for sucking and labeling is not exactly matched with the surface of the object, the first elastic member 222 is self-adaptively deformed due to the stress, so as to adaptively adjust the angle of the suction cup 221 fixed at one end thereof, so that the working surface of the suction cup 221 for sucking and labeling is matched with the surface of the object to be labeled, and the label adsorbed on the working surface is attached to the surface of the object. Optionally, the first elastic member 222 is a spring.

The labeling assembly 22 further comprises a limiting guide shaft 223, the limiting guide shaft 223 penetrates through the first elastic member 222, one end of the limiting guide shaft 223 is fixed to the suction cup 221, the other end of the limiting guide shaft 223 can movably penetrate through the second connecting plate 2124, the limiting guide shaft 223 can limit the first elastic member 222 to stretch and retract only along the axial direction of the limiting guide shaft 223, when the labeling device 20 is used in a scene without the need of adjusting the angle of the suction cup 221 (i.e., when the suction cup 221 is pressed down on an object under the driving of the driving mechanism 21, the working surface of the suction cup 221 for label suction and labeling is just matched with the surface of the object), the driving mechanism 21 drives the labeling assembly 22 to enable the working surface of the suction cup 221 for label suction and labeling to be in contact with the surface of the object, the driving mechanism 21 can further drive downwards to enable the first elastic member 222 to be compressed along the axial direction of the limiting guide shaft 223, so that the acting force between the working surface of the suction cup 221 for label suction and labeling and the surface of the object is increased, and the label is more firmly attached to the surface of the object.

Preferably, when the labeling device 20 is used in a scene where the suction cup 221 is not required to adjust the angle, in order to make the suction cup 221 tightly adhere to the surface of the object and the working surface for label suction and labeling, and to prevent the suction cup 221 from tilting, the number of the limit guide shafts 223 is four, the four limit guide shafts 223 are arranged on the edge of the suction cup 221 in a rectangular array, and correspondingly, the number of the first elastic members 222 is also four, and the four limit guide shafts 223 respectively penetrate through the four first elastic members 222.

Referring to fig. 6, the suction cup 221 further includes a flexible layer, the flexible layer is located on a side away from the first elastic member 222, and the working surface of the suction cup 221 for label suction and labeling is located on the flexible layer, so that when the suction cup 221 is pressed on an object, the working surface of the suction cup 221 for label suction and labeling can be deformed adaptively along with the shape of the wrapping surface under the action of pressure, and thus a label adsorbed on the working surface of the suction cup 221 can be better attached to the surface of the object. The flexible layer in this embodiment may be fixed to the suction cup 221 in a non-detachable manner, or may be fixed to the suction cup 221 in a detachable manner. It should be understood by those skilled in the relevant art that the flexible layer may be understood as a flexible pad, such as a silicone pad or a rubber pad, disposed on the suction cup 221, and may also be understood as a portion of the suction cup 221, the flexible layer portion being made of a flexible material, such as a silicone material or a rubber material.

Referring to fig. 3 and 7, labeling assembly 22 further includes a third connecting plate 224 located between suction cup 221 and second connecting plate 2124, second connecting plate 2124 and third connecting plate 224 are fixed and connected at intervals through stud 226, first elastic element 222 is located between suction cup 221 and third connecting plate 224, one end of limiting guide shaft 223 is fixed to suction cup 221, and the other end penetrates through third connecting plate 224, a space is left between second connecting plate 2124 and third connecting plate 224, the space can be used for installing other structures, and can meet the space requirement for sliding of limiting guide shaft 223 relative to third connecting plate 224, and the portion of limiting guide shaft 223 extending above third connecting plate 224 after sliding relative to third connecting plate 224 can move in the space.

Referring to fig. 6, in order to suck the label to the working surface of the suction cup 221, the suction cup 221 is provided with an air hole, the third connecting plate 224 is provided with a vacuum generator 225, an outlet of the vacuum generator 225 is communicated with the air hole, when the vacuum generator 225 works, the working surface of the suction cup 221 for sucking and labeling the label can generate negative pressure, and the suction cup 221 can suck the label to the working surface under the action of the negative pressure.

Referring to fig. 3 to 7, the labeling device 20 of the present application operates as follows: after the labeling operation is completed, the vacuum generator 225 stops operating, so that the negative pressure on the working surface of the suction cup 221 for sucking and labeling disappears, the driving rod 2122 of the second lifting assembly 212 retracts under the action of the cylinder 2121, and the sliding table 2112 of the first lifting assembly 211 is lifted back to the original point of itself. When the next labeling operation is performed, the label stripping mechanism 30 of the labeling unit 100 strips the label from the base paper of the label tape, the position where the label is stripped is just below the suction cup 221, the vacuum generator 225 operates to make the suction cup 221 generate negative pressure on the working surface for sucking and labeling, so as to suck the label to the working surface for sucking and labeling of the suction cup 221, and the driving mechanism 21 drives the labeling assembly 22 downwards in two cases: in the first case, the distance between the package and the suction cup 221 is short, and the labeling assembly 22 can be driven to the target position only by operating one of the first lifting assembly 211 and the second lifting assembly 212, considering that the first lifting assembly 211 can actively control the stroke of the sliding table 2112 under the driving of the second driving motor 2113, while the driving device of the second lifting assembly 212 is the air cylinder 2121, the general air cylinder 2121 cannot actively control the stroke of the driving rod 2122, and the special air cylinder 2121 increases the cost, so the first lifting assembly 211 is preferably selected; the second situation is when the distance between the parcel and the suction cup 221 is relatively long, requiring the first and second lifting assemblies 211 and 212 to work in concert to drive the labelling assembly 22 to the target position. In this case, the cooperative operation between the first lifting assembly 211 and the second lifting assembly 212 may be driven simultaneously, or one of them may be driven first and the other may be driven later. When the labeling device 20 is used in a scene without the need of adjusting the angle of the suction cup 221 (i.e. when the suction cup 221 is pressed on an article under the driving of the driving mechanism 21, the working surface of the suction cup 221 for sucking and labeling is just adapted to the surface of the article), the labeling device 20 selects the labeling assembly 22 provided with the limiting guide shaft 223, and the driving mechanism 21 drives the labeling assembly 22 to make the working surface of the suction cup 221 for sucking and labeling contact with the wrapping surface, and then the driving mechanism 21 can continue to drive downwards so as to compress the first elastic member 222 along the axial direction of the limiting guide shaft 223, thereby increasing the acting force between the working surface of the suction cup 221 for sucking and labeling and the wrapping surface, and more firmly attaching the label to the wrapping surface; when the labeling device 20 is used in a scene requiring the adjustment of the angle by the suction cup 221, the labeling device 20 selects the labeling assembly 22 without the limiting guide shaft 223, and when the suction cup 221 is driven by the driving mechanism 21 to press on an object, the first elastic member 222 can generate self-adaptive deformation due to stress, so that the angle of the suction cup 221 fixed at one end of the first elastic member can be adjusted in a self-adaptive manner, the working surface of the suction cup 221 for sucking and labeling is adapted to the surface of the object to be labeled, and a label is attached to the surface of the object; when the labeling device 20 is used in a scene where the shape of the surface of the package to be labeled is complex, the suction cup 221 of the labeling device 20 is selected from the suction cups 221 including a flexible layer (the working surface of the suction cup 221 for label suction and labeling is located on the flexible layer), and when the suction cup 221 is pressed on the object, the working surface of the suction cup 221 for label suction and labeling can be deformed adaptively along with the shape of the surface of the package, so that the label adsorbed on the working surface of the suction cup 221 can be better adhered on the surface of the object with a complex shape.
