[0028] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.

[0029] See also Figure 1 , Figure 6 and Figure 7As shown, the coffee machine shell in-mold labeling automation equipment 100 of the present invention is suitable for embedding the label 200 into the fixed mold 410 in the open mold state of the injection mold 400 at the injection molding machine 300, and taking out the coffee machine shell 500 in the movable mold 420 in the open mold state, so as to achieve the purpose of continuous operation of embedding the label 200 and taking out the coffee machine shell 500; of course, according to actual needs, the label 200 can be embedded in the movable mold 420 in the open mold state, and correspondingly, the coffee machine shell 500 in the fixed mold 410 in the open mold state can be taken out, which can also achieve the purpose of continuous operation of embedding the label 200 and taking out the coffee machine shell 500, so it is not limited to this. Among them, the coffee machine shell in-mold labeling automation equipment 100 of the present invention includes an outflow conveyor line 10, a loading and unloading manipulator 20, a reflux conveyor line 30, a label storage and loading machine 40 and a dewatering outlet mechanism 50. The label storage loader 40 and the return conveyor line 30 are each located on the side of the injection molding machine 300 in the width direction (i.e., the direction indicated by arrow A and the opposite direction). Preferably, the label storage loader 40 and the return conveyor line 30 are located on the same side of the injection molding machine 300 in the width direction, for example but not limited to Figure 1 The left side of the display is to improve the continuous operation of the loading and unloading robot 20 placing the coffee machine shell 500 removed by the water outlet 510 of the water outlet removal mechanism 50 on the return conveyor line 30 and then taking out the label 200 from the label storage and loading machine 40, but it is not limited to this. The return conveyor line 30 also extends along the length direction of the injection molding machine 200 (i.e., the direction indicated by arrow A and the opposite direction), and the outflow conveyor line 10 is arranged along the width direction of the injection molding machine 200. The outflow conveyor line 10 is also connected to the return conveyor line 30, and the outflow conveyor line 10 transfers the coffee machine shell 500 transported by the return conveyor line 30 to the return conveyor line 30. Figure 1 The coffee shell 500 is transported to the main conveyor line 600 in the injection molding machine 200 to meet the purpose of subsequent automatic transportation of the coffee shell 500. The loading and unloading robot 20 is arranged across the injection molding machine 200 along the width direction of the injection molding machine 200. The loading and unloading robot 20 takes out the coffee shell 500 in the injection mold 400 and transfers it to the dewatering port mechanism 50 and then places it on the return conveyor line 30. The loading and unloading robot 20 also takes out the label 200 stored at the label loader 40 and buries it in the injection mold 400; the dewatering port mechanism 50 removes the water port 510 of the coffee shell 500 transferred by the loading and unloading robot 20, and the return conveyor line 30 returns the coffee shell 500 without the water port 510 to the outflow conveyor line 10. For example, the outflow conveyor line 10, the return conveyor line 30 and the main conveyor line 600 are each a belt conveyor line. Of course, a chain conveyor line can be selected according to actual needs. Whether it is a belt conveyor line or a chain conveyor line, their structures are well known in the art, so they will not be described here. More specifically, as follows:

[0030] like Figure 1 , Figure 6and Figure 7 As shown, the dewatering mechanism 50 is mounted on the label storage and loading machine 40. Of course, the dewatering mechanism 50 can be mounted on the return conveying line 30 according to actual needs, or installed on the return conveying line 30 and the label storage and loading machine 40 at the same time, so it is not limited to this. Specifically, the return conveying line 30 and the top of the label storage and loading machine 40 are arranged side by side. This arrangement allows the loading and unloading manipulator 20 to more smoothly transfer the coffee machine shell 500 taken out from the injection mold 400 to the dewatering mechanism 50 and the return conveying line 30 in sequence, and the dewatering mechanism 50 removes the water outlet 510 of the coffee machine shell 500 captured by the loading and unloading manipulator 20, and then the return conveying line 30 transports the coffee machine shell 500 without the water outlet 510 to the outflow conveying line 10. For example, the water outlet removal mechanism 50 is a pneumatic or electric scissor mechanism that cuts off the water outlet 510 of the coffee machine shell 500 grasped by the loading and unloading robot 20 by shearing, but the example is not limited to this.

[0031] like Figure 1 As shown, there are two injection molding machines 200, and the two injection molding machines 200 are arranged in a spaced relationship in the width direction. Of course, according to actual needs, the number of injection molding machines 200 can be one, three or four, so it is not limited to this. Among them, each injection molding machine 200 corresponds to a loading and unloading robot 20, a label storage and loading machine 40, a reflux conveyor line 30 and a water removal port mechanism 50. The purpose of this design is to further improve production efficiency. Specifically, in Figure 1 In the figure, the label storage loader 40, the return conveyor line 30 and the water removal port mechanism 50 are arranged alternately with the injection molding machine 200. This ensures a reasonable and compact layout on the one hand, and ensures a more continuous removal and embedding of the label 200 and the removal and unloading of the coffee machine shell 500 on the other hand, but is not limited to this.

[0032] like Figures 6 to 8As shown, the label storage loader 40 includes a loader frame 41, a lifting frame 42, a transverse frame 43, an upper suction nozzle 44, a label storage frame 45, a lifting drive 46 and a transverse drive 47. The loading machine frame 41 has a machine table 41a, which is preferably a platform, but not limited to this; the label storage rack 45 is located above the machine table 41a and is installed on the top of the machine table 41a, and the transverse frame 43 is located below the machine table 41a and can be installed on the bottom of the machine table 41a in the transverse direction of the injection molding machine 200, so that the transverse frame 43 can be moved transversely on the machine table 41a in the width direction of the injection molding machine 200; the lifting frame 42 is straddled with the label storage rack 45 and the machine table 41a along the length direction of the injection molding machine 200, and the lifting frame 42 can also be lifted up and down and assembled with the transverse frame 43. Preferably, the transverse frame 43 is located in the space surrounded by the lifting frame 42, and the end of the transverse frame 43 can be slidably assembled with the lifting frame 42. This arrangement makes the assembly between the transverse frame 43 and the lifting frame 42 more compact. For example, the lifting frame 42 is a "mouth" shape with a closed head and tail, but not limited to this. The lifting drive 46 is located below the machine table 41a and is installed on the transverse frame 43 and the lifting frame 42. For example, the lifting drive 46 is a cylinder or an oil cylinder, and the output end of the cylinder or the oil cylinder is arranged downward. This design makes the assembly connection between the lifting drive 46 and the transverse frame 43 and the lifting frame 42 more compact and reasonable, but not limited to this; the transverse drive 47 is located below the machine table 41a and is installed on the machine table 41a and the transverse frame 43. For example, the transverse drive 47 is an air cylinder or an oil cylinder, which simplifies the structure of the transverse drive 47, but is not limited to this; the upper suction nozzle 44 is located directly above the label storage rack 45 and is installed on the lifting frame 42, so that the upper suction nozzle 44, under the cooperation of the lifting drive 46, the lifting frame 42, the transverse drive 47 and the transverse frame 43, sucks up the label 200 stored in the label storage rack 45 and then transversely moves it along the width direction of the injection molding machine 200 to a loading position away from the label storage rack 45, and the state is shown in FIG. Fig.10c As shown, the labels 200 sucked by the upper and lower suction nozzles 44 are staggered with the label storage rack 45. Specifically, in order to more reliably transfer the labels 200 sucked by the upper suction nozzle 44 to the loading and unloading robot 20, the label storage loading machine 40 further includes a first blowing nozzle 48 and a second blowing nozzle 49 located above the machine table 41a and installed on the machine table 41a. The labels 200 sucked by the upper suction nozzle 44 in the loading position are located above the first blowing nozzle 48 and the second blowing nozzle 49. Fig.10cAs shown, when the label suction mechanism 22 in the loading and unloading robot 20 moves to the position directly below the label 200 sucked by the upper suction nozzle 44 at the loading position, the label suction mechanism 22 sucks the label 200, and the first blowing nozzle 48 and the second blowing nozzle 49 blow air to the label 200 sucked by the label suction mechanism 22, so that the label 200 is closely attached to the label suction mechanism 22. Fig.10f As shown, the upper suction nozzle 44 is reset after the label suction mechanism 22 sucks away the label 200, and the state is shown in FIG. Figure 10d to Figure 10f shown.

[0033] like Figure 2 As shown, the loading and unloading robot 20 includes a multi-axis robot arm 21 and a label suction mechanism 22 and a coffee machine shell suction mechanism 23 installed on the multi-axis robot arm 21. The multi-axis robot arm 21 drives the label suction mechanism 22 and the coffee machine shell suction mechanism 23 to perform multi-axis motion, such as along the XYZ three-axis motion. Of course, according to actual conditions, it can be made to move along four-axis, five-axis or six-axis directions; correspondingly, the multi-axis robot arm 21 is a three-axis robot arm, a four-axis robot arm, a five-axis robot arm or a six-axis robot arm, so it is not limited to this. Specifically, as follows:

[0034] like Figure 4 and Figure 5 As shown, the label suction mechanism 22 includes a mechanism frame 221, a flip driver 222, a model head 223 with a U-shaped profile 2231, vacuum suction nozzles 224 embedded in the U-shaped profile 2231 and arranged in a matrix, and a sponge 225 embedded in the U-shaped profile 2231. The mechanism frame 221 is assembled on the multi-axis robot arm 21, and the multi-axis robot arm 21 provides support and connection; the flip driver 222 is installed at the lower end of the mechanism frame 221, and the mechanism frame 221 provides support for the flip driver 222; the model head 223 is installed at the output end of the flip driver 222 and has an air pipe 226 built in, and a drainage adsorption groove 2232 communicating with the air pipe 226 is opened on the U-shaped profile 2231. This design makes the label 200 more reliably adsorbed by the label absorption mechanism 22, and the adsorbed label 200 is in a "U" shape and is tightly attached to the U-shaped profile 2231 of the model head 223, as shown in the state. Fig.10f For example, there are four vacuum nozzles 224, and they are arranged in the middle of the U-shaped profile 2231. In addition, the flip driver 222 is a flip cylinder. Of course, it can be selected as a motor according to actual needs, so it is not limited to this. In addition, the sponge 225 is used to provide electrostatic adsorption.

[0035] like Figure 3As shown, the coffee machine shell suction mechanism 23 and the label suction mechanism 22 are arranged side by side and spaced apart, and the coffee machine shell suction mechanism 23 comprises a mechanism frame 231, a flip seat 232, a coffee machine shell suction nozzle 233 and a flip cylinder 234 for driving the flip seat 232 to flip up and down. The mechanism frame 231 is mounted on the multi-axis robot arm 21, and the multi-axis robot arm 21 provides support for the mechanism frame 231; the cylinder body 2341 of the flip cylinder 234 is mounted on the mechanism frame 231 in an up-and-down arrangement, and the mechanism frame 231 provides support for the flip cylinder 234; the flip seat 232 is pivotally connected to the lower end of the cylinder body 2341, the piston rod 2342 of the flip cylinder 234 is hinged to the flip seat 232, and the coffee machine shell suction nozzle 233 is mounted on the flip seat 232; the flip cylinder 234 drives the flip seat 232 together with the coffee machine shell suction nozzle 233 on the flip seat 232 Switching between a horizontal position and a vertical position allows the coffee machine shell suction nozzle 233 to be used to transfer the coffee machine shell 500 in the injection mold 400 when flipped to the vertical position, and allows the coffee machine shell suction nozzle 233 to be used to transfer the coffee machine shell 500 taken out of the injection mold 400 to the dewatering port mechanism 50 when flipped to the horizontal position, and the dewatering port mechanism 50 removes the dewatering port 510, and finally places the coffee machine shell 500 after the dewatering port 510 on the reflux conveyor line 30, and the reflux conveyor line 30 refluxes the coffee machine shell 500 to the external conveyor line 10, but is not limited to this description.

[0036] Combination Figures 10a to 10f , how the loading and unloading robot takes out the labels and stores the labels of the loading machine is explained: first, the multi-axis robot arm 21 moves its label suction mechanism 22 to Fig.10a At the same time, the upper suction nozzle 44 slides downward under the cooperation of the lifting drive 46, the lifting frame 42, the lateral frame 43 and the lateral drive 47 until the upper suction nozzle 44 absorbs the top label 200 stored in the label storage rack 45. Fig.10a Then, the lifting drive 46 drives the lifting frame 42 together with the upper suction nozzle 44 and the sucked label 200 along Fig.10a Then, the traverse drive 47 drives the traverse frame 43, the lifting drive 46, the lifting frame 42, the upper suction nozzle 44 and the sucked label 200 together along Fig.10b Move horizontally to the loading position in the direction indicated by the middle arrow. Fig.10bAs shown; secondly, the lifting driver 46 drives the lifting frame 42 together with the upper suction nozzle 44 and the sucked label 200 to slide downward until they are in contact with the model head 223 in the label suction mechanism 22, and the vacuum nozzle 224 of the label suction mechanism 22 sucks the label 200 sucked by the upper suction nozzle 44. At this time, the upper suction nozzle 44 releases the suction of the label 200, so that the label 200 sucked by the upper suction nozzle 44 is sucked to the model head 223. After the label 200 sucked by the upper suction nozzle 44 is sucked to the model head 223, the upper suction nozzle 44 is reset to the right with the cooperation of the lifting driver 46, the lifting frame 42, the transverse frame 43 and the transverse driver 47. The state is shown in FIG. Fig.10d As shown, the upper suction nozzle 44 is prepared to take out the label 200 from the label storage rack 45 next time; then, under the electrostatic adsorption generated by the sponge 225 and the vacuum negative pressure formed by the vacuum suction nozzle 224 and the drainage adsorption groove 2232, the two ends of the label 200 adsorbed to the middle position of the model head 223 gradually approach the U-shaped contour 2231 of the model head 223, and the state is shown in FIG. Fig.10e Finally, under the blowing cooperation of the first blowing nozzle 48 and the second blowing nozzle 49, the label 200 is finally close to the U-shaped profile 2231 of the model head 223, and the state is shown Fig.10f As shown, the purpose of the loading and unloading robot 20 taking out the label 200 from the label storage and loading machine 22 is achieved.

[0037] Compared with the prior art, since the label storage feeder 40 and the return conveyor line 30 are respectively located at the side of the injection molding machine 200 in the width direction, the return conveyor line 30 also extends along the length direction of the injection molding machine 200, the outflow conveyor line 10 is arranged along the width direction of the injection molding machine 200 and docked with the return conveyor line 30, the loading and unloading robot 20 is straddled on the injection molding machine 200 along the width direction of the injection molding machine 200, and the loading and unloading robot 20 first embeds the label 200 taken out from the label storage feeder 40 into the injection mold 400 before taking out the coffee machine shell 500 in the injection mold 400, so that the embedding of the label 200 and the taking out of the coffee machine shell 500 are carried out in sequence; at the same time, the loading and unloading robot 20 takes out the coffee machine shell 500 0 is first transferred to the water outlet mechanism 50 and then placed on the reflux conveyor line 30, and then the label 200 is taken out from the label storage and loading machine 40, so that the unloading of the coffee machine shell 500 and the taking of the label 200 are carried out in sequence and in an orderly and coherent manner; and the water outlet mechanism 50 removes the water outlet 510 of the coffee machine shell 500 transferred by the loading and unloading robot 20, and the reflux conveyor line 30 returns the coffee machine shell 500 placed by the loading and unloading robot 20 and without the water outlet 510 to the outflow conveyor line 10, and is subsequently transported by the outflow conveyor line 10, so that the continuity among the embedding of the label 200, the taking out of the coffee machine shell 500, the unloading of the coffee machine shell 500, the taking of the label 200 and the subsequent transportation of the coffee machine shell 500 is good, thereby improving efficiency.
