[0029] The present invention is described in detail below in conjunction with various embodiments, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0030] like Figure 1 As shown, an embodiment of the present invention provides a tray labeling machine, which includes: a feeding mechanism 1, a lifting mechanism 2, a label supplying mechanism 3, a labeling mechanism 4, a descending mechanism 5, a discharging mechanism 6 and a conveyor belt 7.

[0031] like Figure 2 As shown, the feeding mechanism 1 is used to realize continuous feeding of material trays, which includes: a feeding conveyor line 11, a plurality of trays 12 moving along the feeding conveyor line 11, and the feeding conveyor line 11 includes: a feeding conveying motor 111, a feeding conveying chain 112 driven by the feeding conveying motor 111, and a feeding slide rail 113 for fixing the feeding conveying chain 112.

[0032] Among them, a plurality of trays can be placed in a stacked manner on any tray 12. Any tray 12 includes: a tray body 121 and a plurality of limit rods 122 arranged on the tray body 121. In one embodiment, there can be four limit rods 122, and the four limit rods 122 are distributed at the four corners of a rectangle or square. The spacing between the four limit rods 122 can be set according to the specifications of the circulating trays.

[0033] like Figure 3 As shown, the lifting mechanism 2 is used to lift the conveyed material tray so as to facilitate its turnover to the conveyor belt 7. Specifically, the lifting mechanism 2 is located at the downstream end of the feed conveyor line 11, and includes: a lifting motor 21, a lifting screw, a lifting slider 22 and a lifting fork 23. The lifting motor 21 can drive the lifting screw to pivot through a transmission belt, the lifting screw passes through the lifting slider 22 and is threadedly matched with the lifting slider 22, and the lifting fork 23 is connected to the lifting slider 22.

[0034] In this way, when several stacked trays move to the lifting mechanism 2, the lifting fork 23 is inserted under the tray and lifts the tray to the required height to facilitate subsequent turnover. When the next tray needs to be lifted, the lifting mechanism 2 can move away from the tray as a whole, the lifting fork 23 is lowered, and the lifting mechanism 2 moves closer to the tray as a whole so as to be inserted under the next tray. The overall movement of the lifting mechanism 2 can be achieved by a linear motor.

[0035] The conveyor belt 7 extends from between the lifting mechanism 2 and the label supply mechanism 3 to the lowering mechanism 5 . The labeling mechanism 4 is arranged along the conveyor belt 7 and is located downstream of the label supply mechanism 3 .

[0036] like Figure 4 As shown, the label supply mechanism 3 is used to provide labels, which includes: a printer 31, a label output head 32, a pressing block 33 and a cylinder 34. The label output head 32 is arranged at the label output port of the printer 31. Among them, the pressing block 33 is located above the label output head 32, and is driven by the cylinder 34 to move toward or away from the label output head 32. In this way, the label printed by the printer 31 is sent out from the label output head 32, and the pressing block 33 can press down the sent label under the drive of the cylinder 34, and separate it from the adjacent label under the downward pressure force, waiting for the labeling mechanism 4 to pick it up. In one embodiment, the labeling mechanism 4 is a SCARA labeling robot.

[0037] In addition, in order to ensure the accuracy of labeling, the tray labeling machine also includes a visual positioning mechanism, which includes industrial cameras, which are distributed on both sides of the labeling mechanism 4. In this way, before labeling, the industrial camera can identify the tray to confirm the position suitable for labeling. According to the confirmed labeling position, the SCARA labeling robot picks up the label and sticks it at the corresponding labeling position. Then, the conveyor belt 7 continues to drive the tray to the bottom of another industrial camera, and the other industrial camera detects the pasted label to determine whether its fitting position meets the requirements.

[0038] like Figure 5 As shown, the descending mechanism 5 is used to re-stack the labeled trays, and its structure is similar to the above-mentioned lifting mechanism 2. Specifically, the descending mechanism 5 includes: a descending motor 51, a descending screw rod, a descending slider 52 and a descending lifting fork 53. The descending motor 51 can drive the descending screw rod to pivot through a transmission belt, the descending screw rod passes through the descending slider 52 and is threadedly engaged with the descending slider 52, and the descending lifting fork 53 is connected to the descending slider 52.

[0039] In this way, the lifting fork 53 is lowered to place the labeled tray on the tray of the discharging mechanism 6, and then the lifting fork 53 is lowered to continue to receive another labeled tray, and the lowering mechanism 5 is continued to be placed on the previous tray. Then, the lowering mechanism 5 can move away from the tray as a whole to separate from the tray, and the lowering mechanism 5 returns to the initial position as a whole, and repeats the above unloading action. The overall movement of the lowering mechanism 5 can be achieved by a linear motor.

[0040] Again Figure 1As shown, the tray labeling machine further includes: a turnover mechanism 8. The turnover mechanism 8 is arranged between the lifting mechanism 2 and the upstream end of the conveyor belt 7 and between the downstream end of the conveyor belt 7 and the descending mechanism 5, so as to facilitate the rotation of the tray from the lifting mechanism 2 to the conveyor belt 7, and the rotation of the tray from the conveyor belt 7 to the descending mechanism 5. In one embodiment, the turnover mechanism 8 includes: a linear motor 81, and a clamp 82 driven by the linear motor 81 to reciprocate. The clamp 82 can be an existing mechanical pneumatic clamp, or a suction cup gripper.

[0041] like Figure 6 As shown, in order to realize the recycling of the pallet 12, a circulation mechanism 9 is further provided between the feeding mechanism 1 and the discharging mechanism 6. Specifically, the circulation mechanism 9 includes: a circulating conveying line 91, one end of the circulating conveying line 91 is arranged near the downstream end of the feeding conveying line 11, and the other end is arranged near the upstream end of the discharging conveying line. Among them, the circulating conveying line 91 includes: a circulating conveying motor 911, a circulating conveying chain 912 driven by the circulating conveying motor 911, and a circulating slide rail 913 for fixing the circulating conveying chain 912. In this way, the empty pallet 12 can be circulated from the upstream end of the circulating conveying line 91 to the downstream end, so as to be provided to the discharging mechanism 6 for continued use.

[0042] In order to facilitate the turnover of the tray 12 between the circulation mechanism 9 and the feeding mechanism 1 and the discharging mechanism 6, a plurality of guide rollers 92 are also provided in the circulation slide 913. The plurality of guide rollers 92 are respectively provided at both ends of the circulation slide 913, and the plurality of guide rollers 92 at either end are arranged side by side according to the corresponding feeding direction or discharging direction. In addition, the plurality of guide rollers 92 at either end are mounted on a bracket, and a lifting cylinder is also provided at the bottom of the bracket. By providing the lifting cylinder, the height of the plurality of guide rollers 92 can be adjusted so as to be aligned with the feeding conveying line 11 and the discharging conveying line.

[0043] like Figure 7 As shown, the discharging mechanism 6 is used to discharge the material tray with labels, and its structure is similar to the above-mentioned feeding mechanism 1. Specifically, the discharging mechanism 6 includes: a discharging conveying line 61, and a plurality of trays 62 moving along the discharging conveying line 61. The upstream end of the discharging conveying line 61 is arranged close to the descending mechanism 5. Among them, the discharging conveying line 61 includes: a discharging conveying motor 611, a discharging conveying chain 612 driven by the discharging conveying motor 611, and a discharging slide rail 613 fixing the discharging conveying chain 612.

[0044] Among them, a plurality of trays can be placed in a stacked manner on any tray 62. Any tray 62 includes: a tray body 621 and a plurality of limit rods 622 arranged on the tray body 621. In one embodiment, there can be four limit rods 622, and the four limit rods 622 are distributed at the four corners of a rectangle or a square. The spacing between the four limit rods 622 can be set according to the specifications of the circulating trays.

[0045] In addition, the upstream end of the feed conveyor is connected to the external feed slide rail, and the downstream end of the discharge conveyor line 61 is connected to the external discharge slide rail 613, so that the tray can be transferred to the feed mechanism 1 through the slide rail, or transferred to the next station from the discharge mechanism 6. Alternatively, an AGV trolley can also be used. In this case, the tray labeling machine also includes an AGV trolley, which transfers the products to be labeled to the feed mechanism 1, and the products that have been labeled leave the discharge mechanism 6.

[0046] In summary, the tray labeling machine of the present invention can realize continuous loading, labeling and unloading of trays with high efficiency. At the same time, by combining the linear feeding mechanism and the discharging mechanism, while realizing continuous loading and unloading, it can also be applicable to the feeding and discharging of trays of different specifications, fully meeting the needs of actual industrial production.

Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
