Detailed Description

The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.

A plastic cup sleeve label forming device, comprising: a conveying track 1, a righting structure 2, a rotating disc 3 and a labeling machine 4. The conveying track 1 and the labeling machine 4 are arranged along the circumferential direction of the rotating disc 3. The conveying track 1 can adopt the existing conveying structure and can convey the plastic cups from one end to the other end. The conveying rail 1 is provided with a limiting plate 11. Limiting plates 11 are provided on both sides of the conveying rail 1, respectively. The spacing between the limiting plates 11 corresponds to the diameter of the plastic cup. When the plastic cup is placed on the conveying track 1, the limiting plate 11 can be attached to the side face of the plastic cup.

The rotating disk 3 is provided with a bearing post 31, a driven gear 32 and a stepping motor 33. The number of the carrying posts 31 is plural. The carrying posts 31 are provided on one side of the rotating disk 3 near the conveying rail 1 and are arranged in the circumferential direction of the rotating disk 3. The carrying column 31 includes a guide portion 311 and a positioning portion 312. The guide portion 311 is fixedly provided at an end of the positioning portion 312 remote from the rotating disk 3. At the same time, the guide portion 311 coincides with the axis of the positioning portion 312. The guide 311 has a tapered cross section. The area diameter of the guide portion 311 is larger as it approaches the positioning portion 312. The positioning portion 312 has a cylindrical shape. The diameter of the positioning portion 312 corresponds to the diameter of the plastic cup.

The driven gear 32 and the stepping motor 33 are disposed on the side of the rotary disk 3 away from the carrying column 31. The driven gear 32 is connected to the rotating disk 3. The stepper motor 33 is in driving connection with the driven gear 32. Thereby, the rotating disk 3 can rotate relative to the conveying rail 1 and the labeling machine 4 under the drive of the stepping motor 33, and the plastic cup can be driven to move from the conveying rail 1 to the labeling machine 4.

The righting structure 2 is arranged at the output end of the conveying track 1. The righting structure 2 comprises a turning plate 21, a transmission structure 22, a righting rod 23 and an air cylinder 24. The positioning rod 23 includes a guide rod 231 and a stopper rod 232. The stopper rod 232 is disposed in a vertical direction. One end of the limit lever 232 is connected to the cylinder 24, and the other end is connected to the guide lever 231. An included angle is provided between the guide bar 231 and the numerical direction. The number of the normal position levers 23 is two. Mirror symmetry exists between the two righting rods 23. The two limiting rods 232 are parallel to each other and a gap is arranged between the two limiting rods. The righting rod 23 can move in the vertical direction relative to the conveying track 1 under the drive of the cylinder 24. Preferably, the righting bar 23 is circular in cross-section. Meanwhile, the cylinder 24 is fixedly provided on a base. The base is provided with a rotating bearing, and the rotating bearing surrounds the periphery of the base. The base is connected to the rotating disc 3 by means of the rotating bearing. Thus, the rotary disk 3 can be rotated with respect to the cylinder 24 even when rotated. Meanwhile, a sliding block and a sliding rail are further arranged on the base, and the sliding block and the sliding rail are arranged along the radial direction of the base. The slide blocks of the slide block slide rail are connected with the air cylinders 24. Thereby, the slider can drive the righting rod 23 to move in the radial direction of the base by the cylinder 24.

The transmission structure 22 comprises a trigger lever 221, a driven lever 222 and a supporting frame 223. The supporting frame 223 is provided at the output end of the conveying rail 1 and fixedly connected with the frame of the conveying rail 1 itself. The end of the support frame 223 remote from the conveyor track 1 is also provided with a projection. When the plastic cup moves onto the support shelf 223, the projection can engage with the outer edge of the plastic cup to block continued travel of the plastic cup. The flap 21 is rotatably connected to the support frame 223, so that the flap 21 can be turned relative to the conveyor track 1 in a direction toward the rotary disk 3. When the flap 21 is turned over, the plastic cup can pass through the support 223. Meanwhile, a torsion spring is provided between the flap 21 and the support frame 223. The passive rod 222 itself is n-type. One end of the passive lever 222 is rotatably connected to the flap 21. The other end of the passive lever 222 is rotatably connected to the trigger lever 221. Meanwhile, the trigger lever 221 is rotatably connected to the supporting frame 223. The end of the trigger lever 221 remote from the passive lever 222 corresponds to the movement path of the normal lever 23.

In practical use, the production of plastic cups involves several links. After the finished plastic cup is produced, quality inspection is required by staff to pick out defective products in advance. After quality inspection is carried out on the plastic cups by staff, the plastic cups passing the quality inspection are placed on the conveying track 1 so as to carry out a final labeling and packaging link. Specifically, when placing the plastic cup, it is necessary to orient the cup mouth of the plastic cup toward the conveying rail 1 and orient the handle toward the output end of the conveying rail 1. If the above conditions are not met, the operation is abnormal.

When the plastic cup is placed on the conveying track 1, the plastic cup is initially limited by the limiting plate 11, so that the handle of the plastic cup is limited in a fixed area. However, the postures of different plastic cups still show different states due to the reasons of manual placement, mutual extrusion among the plastic cups, vibration of equipment in the conveying process and the like. Specifically, the state shown in the drawings is presented.

The plastic cup is gradually moved to the output end of the conveying track 1 under the driving of the conveying track 1. At this point the plastic cup is detached from the conveyor track 1, but under the subsequent squeezing of the plastic cup, it will move onto the flap 21. At this time, the plastic cup is directly above the carrying post 31. The cylinder 24 is driven, and the righting rod 23 moves along the vertical direction under the driving of the cylinder 24. During movement, the guide bar 231 will be in contact with the handle of the plastic cup. Because an included angle exists between the guide rod 231 and the vertical direction, the handle is slowly stirred in the process of moving the guide rod 231 along the vertical direction, so that the handle gradually moves towards the gap between the two limiting rods 232. Eventually, the handle will move to a position corresponding to the gap.

After the handle is moved to a position corresponding to the gap, the guide bar 231 continues to move so as to be in contact with the trigger bar 221. The trigger lever 221 is pushed by the guide lever 231. At this time, the trigger lever 221 presses the passive lever 222 with the connection with the support frame 223 as a fulcrum, so that the passive lever 222 moves in a direction opposite to the movement direction of the normal lever 23. Thereby, the flap 21 is pressed by the passive lever 222 to turn. When the flap 21 is turned over, the plastic cup will fall through the support shelf 223 onto the load post 31. Meanwhile, in the falling process of the plastic cup, the handle of the plastic cup is always positioned in the gap between the limiting rods 232. In the process of turning the turning plate 21, the guiding portion 311 is tapered, so that the turning process of the turning plate 21 does not interfere with the guiding portion 311. Meanwhile, the guide part 311 can guide the plastic cup when the plastic cup falls down, thereby playing a certain deviation rectifying role in the falling process of the plastic cup. Eventually the plastic cup will fit over the detent 312. At this time, the cylinder 24 is reversely operated to drive the normal position lever 23 to return to the initial position. When the guide rod 231 is separated from the trigger rod 221, the turning plate 21 is reset to the initial position under the action of the torsion spring, and drives the transmission structure 22 to reset to the initial position.

It should be noted that the conveying speed of the conveying track 1 should not be too high in order to avoid that the extrusion of the following plastic cup adversely affects the falling process of the preceding plastic cup.

When the plastic cup is sleeved on the positioning part 312, the slide block on the base acts to drive the righting rod 23 to move away from the conveying track 1 through the air cylinder 24, so that the handle is separated from the gap between the limiting rods 232. At this time, the stepping motor 33 is operated, and the rotating disk 3 starts to rotate under the drive of the stepping motor 33, so that the next adjacent carrying column 31 is rotated to a position corresponding to the conveying rail 1. At the same time, the carrier column 31 currently carrying the plastic cups is moved in a direction approaching the labelling machine. When the empty bearing column 31 moves to a position corresponding to the conveying track 1, the sliding rail of the sliding block acts reversely, so that the air cylinder 24 drives the righting rod 23 to reset to the initial position. Thereby, the foregoing process is repeatedly performed, so that the plastic cups can be dropped one by one onto the rotating disc 3.

The plastic cup moves gradually to the labeling machine 4 under the drive of the rotating disc 3. When the plastic cup is moved to a position corresponding to the labelling machine 4, the labelling machine 4 will label the sleeve on the side wall of the plastic cup. The plastic cup with the sleeve label attached can be removed from the carrying column 31 by a mechanical arm or a worker.

In conclusion, the utility model can effectively adjust the gesture of the plastic cup, so that the handle of the plastic cup can not have adverse effect on the labeling process of the labeling machine. Meanwhile, the actual labeling position of the labeling machine is overlapped with the preset labeling position, and a large amount of offset of the actual labeling position can not be generated due to the change of the gesture of the plastic cup. When patterns exist on the surface of the plastic cup, the sleeve marks can not shade the patterns on the plastic cup due to the deviation of the actual labeling positions. Thus, the utility model can be fully suitable for the plastic cup with the handle.

It should be noted that the foregoing labeling machine 4 may be a full-automatic single-sided labeling machine disclosed in chinese patent [ application No.: CN201720460933.8, publication No.: CN 206704711U).
