[0044] The label delivery mechanism 20 is arranged on one side of the machine 10 along the first direction of the labeling machine 100; the feeding conveying line body 30 is arranged on the machine 10 and arranged side by side with the label delivery mechanism 20 along the first direction; the clamping and positioning mechanism 40 is arranged on the machine 10 and arranged between the label delivery mechanism 20 and the feeding conveying line body 30; the turntable mechanism 50 is arranged on the machine 10 and is located at the delivery end of the feeding conveying line body 30, the turntable mechanism 50 includes a turntable 51 and a plurality of positioning fixtures 52, the turntable 51 can be rotatably arranged, and the outer periphery of the turntable 51 is arranged with material clamping stations, labeling stations, missing label detection stations and material discharge stations at intervals along its rotation direction, and the plurality of positioning fixtures 52 The positioning fixtures 52 are arranged on the turntable 51 at intervals along the circumferential direction of the turntable 51, and each positioning fixture 52 can flow through the clamping station, the labeling station, the missing label detection station and the discharge station in sequence; the discharge conveyor line 60 is arranged on the machine 10 and arranged on one side of the turntable mechanism 50 along the first direction; the delivery line 70 is arranged on the machine 10 and arranged on the side of the discharge conveyor line 60 away from the turntable mechanism 50 along the first direction; the transfer mechanism 80 is arranged on the machine 10, and the moving stroke of the transfer mechanism 80 covers the discharge conveyor line 60 and the delivery line 70, and the transfer mechanism 80 is used to transfer the product from the discharge conveyor line 60 to the delivery line 70.

[0045] In summary, the implementation of the technical solution of this embodiment will achieve the following beneficial effects: the layout structure of the label delivery mechanism 20, the feed conveyor line 30, the clamping and positioning mechanism 40, the turntable mechanism 50, the discharge conveyor line 60, the delivery line 70 and the transfer mechanism 80 on the machine 10 is reasonable and compact, making full use of the table space of the machine 10, so that the overall structure of the labeling machine 100 is simple, the volume is small, the installation space is small, the product flow path between the functional components is short, which helps to reduce the processing time and improve the production efficiency; specifically, when working, the product is loaded through the feed conveyor line 30, the product is moved to the turntable mechanism 50 through the feed conveyor line 30, and the positioning fixture 52 of the turntable mechanism 50 places the product After the material is clamped and picked up, the turntable 51 rotates in a preset direction and at a preset angle, and the product arrives at the clamping and positioning mechanism 40; the clamping and positioning mechanism 40 then clamps and positions the product, and the label feeding mechanism 20 feeds the label to the clamping and positioning mechanism 40 and sticks it to the surface of the product; after the labeling process is completed, the turntable 51 continues to drive the product to move to the discharge conveyor line 60, and releases the product into the discharge conveyor line 60, and then the transfer mechanism 80 picks up the product and transfers it to the delivery line 70, and the delivery line 70 transfers the product that has completed the labeling process to the next workstation; since a plurality of positioning fixtures 52 are arranged on the turntable 51, as the turntable 51 continuously rotates, continuous labeling of multiple products can be achieved, thereby greatly improving the processing efficiency.

[0046] Please continue reading Figure 1 In one embodiment, the feed conveyor line 30 includes a conveying mechanism 31 and a material blocking mechanism 32. The feeding end of the feed conveyor line 30 extends to the outside of the machine 10, and the delivery end of the feed conveyor line 30 is engaged with the turntable mechanism 50; the material blocking mechanism 32 is arranged at the delivery end of the feed conveyor line 30 to block or release the product.

[0047] The conveying mechanism 31 is used to connect the loading station and the turntable mechanism 50. The products to be labeled are loaded from the loading station into the conveying mechanism 31. The conveying mechanism 31 continuously transfers the products to the turntable mechanism 50 for the positioning fixture 52 to grab. The conveying mechanism 31 can be, but is not limited to, a synchronous belt pulley mechanism, a sprocket mechanism, or the like.

[0048] Usually, there is a certain angle between two adjacent positioning clamps 52 on the turntable 51, which means that there will be an interval between the two adjacent positioning clamps 52 when they move to the delivery end of the conveying mechanism 31. The function of the material blocking mechanism 32 is to block the product from continuing to move before the current positioning clamp 52 rotates to align with the delivery end, thereby preventing the product from falling out or causing the positioning clamp 52 to be unable to effectively grasp the product.

[0049] For example, the material blocking mechanism 32 is composed of a cylinder and a material blocking plate. The cylinder drives the material blocking plate to extend into the conveying mechanism 31 to block the product stroke, and exits the conveying mechanism 31 to restore the normal conveyance of the product to the turntable mechanism 50.

[0050] Please continue reading Figure 3 In one embodiment, the clamping and positioning mechanism 40 is arranged at the labeling station. The clamping and positioning mechanism 40 includes a clamping bracket 41, a first positioning clamping component 42 and a second positioning clamping component 43. The clamping bracket 41 is arranged on the machine 10. The first positioning clamping component 42 and the second positioning clamping component 43 are arranged on the clamping bracket 41 with a vertical interval and opposite to each other. The first positioning clamping component 42 and the second positioning clamping component 43 can cooperate to clamp or release the product. When the product rotates to the labeling station with the turntable 51, the product immediately enters the gap between the first positioning clamping component 42 and the second positioning clamping component 43, and then the first positioning clamping component 42 and the second positioning clamping component 43 extend toward each other to clamp and position the product, so as to prevent the product from loosening and shifting during labeling, thereby affecting the labeling quality.

[0051] For example, in an optional embodiment, the first positioning clamping assembly 42 includes a first positioning clamping cylinder 421 and a first clamping body 422, and the second positioning clamping assembly 43 includes a second positioning clamping cylinder 431 and a second clamping body 432. The first positioning clamping cylinder 421 and the second positioning clamping cylinder 431 are respectively installed on the clamping bracket 41, the first clamping body 422 is connected to the telescopic shaft of the first positioning clamping cylinder 421, and the second clamping body 432 is connected to the telescopic shaft of the second positioning clamping cylinder 431, and the second clamping body 432 and the first clamping body 422 can move closer to or away from each other. Therefore, the structural composition and working principle of the first positioning clamping assembly 42 and the second positioning clamping assembly 43 are simple, and the response speed to the clamping, positioning and release of the product is fast, and the reliability is high.

[0052] It should be noted that when the product is a cylindrical lipstick, the relatively disposed clamping surfaces of the first clamping body 422 and the second clamping body 432 can be provided with concave surfaces, and the concave surfaces fit closely with the outer cylindrical surface of the lipstick to increase the contact area and improve the clamping stability.

[0053] Please continue reading Figure 4In addition, on the basis of any of the above embodiments, the turntable mechanism 50 further includes a rotating seat 53 and a driving assembly 54, a rotatable shaft 55 is arranged on the rotating seat 53, one end of the shaft 55 is connected to the driving assembly 54, and the other end of the shaft 55 is connected to the turntable 51, and the driving assembly 54 is arranged on the rotating seat 53; wherein, a plurality of positioning fixtures 52 are distributed at equal angles on the turntable 51. During operation, the driving assembly 54 drives the shaft 55 to rotate, and then the turntable 51 can be driven to rotate at a preset speed and in a preset direction through the shaft 55, so as to drive each positioning fixture 52 to pass through each processing station in sequence. Since the plurality of positioning fixtures 52 are distributed at equal angles on the turntable 51, the driving assembly 54 can drive the turntable 51 to rotate at a uniform speed, ensuring that each rotation of a preset angle can enable the positioning fixture 52 to accurately flow from the current station to the next station.

[0054] Furthermore, the turntable mechanism 50 also includes a stand 56, a slip ring module 57 and an electric control module 58. The stand 56 is vertically mounted on the upper surface of the rotating seat 53. The slip ring module 57 is suspended and mounted on one end of the stand 56 away from the rotating seat 53. The slip ring module 57 is rotatably matched with the turntable 51. The electric control module 58 is arranged on the turntable 51 and is electrically connected to the slip ring module 57 and the positioning fixture 52. Cables, air pipes and other components are installed inside the slip ring module 57, allowing the turntable 51 to form electrical and air connections with the electric control module 58 and the positioning fixture 52 in a rotating state, which satisfies the normal operation of the positioning fixture 52 while avoiding twisting and winding of the cables, air pipes and other components due to the rotation of the turntable 51, thereby improving the working reliability of the positioning turntable mechanism 50.

[0055] Please continue reading Figure 5 In addition, in another embodiment, the discharge conveyor line 60 includes a base 61, a power source 62, a transmission assembly 63 and a plurality of loading blocks 64, the power source 62 is arranged on the base 61, the transmission assembly 63 is rotatably arranged on the base 61 and is transmission-connected to the power source 62, a plurality of loading blocks 64 are arranged on the outer periphery of the transmission assembly 63 at intervals along the rotation direction of the transmission assembly 63, the loading block 64 is provided with a connected accommodating groove 641 and a notch 642, the accommodating groove 641 is extended along a first direction of the loading block 64, and the notch 642 is extended along a second direction of the loading block 64, wherein the first direction intersects with the second direction.

[0056] During operation, the power source 62 drives the transmission assembly 63 to rotate, so that the transmission assembly 63 drives the loading block 64 to rotate. The movement of the loading block 64 is adapted to the rotation speed of the positioning fixture 52, so that different positioning fixtures 52 and the loading block 64 can move synchronously to the unloading station. The positioning fixture 52 releases the labeled product into the receiving groove 641. The receiving groove 641 has a positioning effect on the product to ensure that the product is placed firmly on the loading block 64. The notch 642 allows the gripper of the transfer mechanism 80 to extend into the receiving groove 641 to effectively clamp the product, so as to transfer the product from the discharge conveying line body 60 to the delivery line body 70.

[0057] In some special cases, the transfer mechanism 80 may not have enough time to grab the product in the discharging conveyor line 60. In order to avoid the product from being squeezed and damaged, in one embodiment, the discharging conveyor line 60 also includes a guide bin 65 and a lifting block. The guide bin 65 is arranged on the base 61. The guide bin 65 is provided with a guide channel that penetrates the structure. The lifting block is arranged at the bottom of the feed inlet of the guide channel. When the moving loading block 64 intersects with the lifting block, the lifting block can automatically insert into the bottom of the receiving groove 641 and extend under the product. Finally, the product is lifted up and leaves the receiving groove 641 by means of the relative motion relationship and rolls onto the lifting block, and finally rolls along the guide channel to the centralized collection point.

[0058] Please continue reading Figure 1 and Figure 2 In one embodiment, the transfer mechanism 80 includes a support frame 81, a transverse module 82 and a gripper module 83. The support frame 81 is arranged across the discharge conveyor line 60 and the delivery line 70. The transverse module 82 is arranged on the support frame 81 and is used to output a reciprocating force between the discharge conveyor line 60 and the delivery line 70. The gripper module 83 is connected to the transverse module 82 and can reciprocate between the discharge conveyor line 60 and the delivery line 70; wherein the gripper module 83 includes a plurality of grippers arranged side by side, and the grippers are used to grab or release products. The gripper module 83 is driven by the transverse movement module 82 to move back and forth between the discharge conveyor line 60 and the delivery line 70 in a straight line trajectory, and the gripper module 83 includes multiple gripper members, each of which can grab at least one product at a time, so that the transfer mechanism 80 can realize a single simultaneous transfer of multiple products, greatly improving the transfer efficiency of the products between the discharge conveyor line 60 and the delivery line 70.

[0059] Optionally, the gripper may be, but is not limited to, any one of a mechanical clamp, a suction cup, etc., and may be flexibly selected according to actual needs.

[0060] In addition, based on any of the above embodiments, the labeling machine 100 further includes a marker 90, which is disposed above the delivery line 70. When the labeled product moves in the delivery line 70, it passes through the marker 90, and the marker 90 marks identification information such as brand, name, and production date on the appearance of the product.

[0061] For example, the marker 90 may be, but is not limited to, a laser marker 90 .

[0062] 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.
