[0032] according to Figures 1 to 3 The utility model provides a cigarette box automatic positioning device for transport vehicles of different specifications, including a frame base 1, a horizontal turntable 3 and a cigarette box clamp.

[0033] A horizontal rotary motor 2 is disposed inside the frame base 1 , and a horizontal turntable 3 is disposed above the frame base 1 and connected to an output shaft of the horizontal rotary motor 2 to drive the horizontal turntable 3 to rotate in a circumferential direction.

[0034] A guide slot 4 is provided on one side of the horizontal turntable 3 , a transverse guide rail 5 is movably engaged in the guide slot 4 , and a cigarette box clamp is arranged at the end of the transverse guide rail 5 .

[0035] A left positioning motor 9 is also provided on the top of the horizontal turntable 3. The output shaft of the left positioning motor 9 is fixedly connected to a gear 10. A rack 11 is provided on the transverse guide rail 5. The gear 10 and the rack 11 are adapted to mesh with each other to drive the transverse guide rail 5 to move along the guide groove 4.

[0036] Furthermore, the cigarette box clamp includes a left end positioning plate 6 , a right end positioning plate 8 and a right end positioning motor 12 .

[0037] The left end positioning plate 6 is arranged at the end of the transverse guide rail 5 away from the horizontal turntable 3, and the right end positioning plate 8 is sleeved on the middle part of the transverse guide rail 5 through the guide sleeve 7, and the right end positioning plate 8 is perpendicular to the transverse guide rail 5 and parallel to the left end positioning plate 6 in the same horizontal plane.

[0038] The right positioning motor 12 is fixed to one end of the transverse guide rail 5 close to the horizontal turntable 3, and the output shaft of the right positioning motor 12 is fixedly connected with a transmission screw 13, and the back side of the guide sleeve 7 is fixedly connected with a nut 14, and the transmission screw 13 is adapted to mesh with the nut 14 to drive the right end positioning plate 8 to move along the transverse guide rail 5.

[0039] In this embodiment, the frame base 1 is arranged on the side of the cigarette box conveyor belt and is parallel to it. When the left side of the cigarette box on the conveyor belt needs to be positioned, the left end positioning plate 6 and the right end positioning plate 8 are first opened away from each other, so that the left end of the transverse guide rail 5 and the left end positioning plate 6 are located on the left side of the cigarette box conveyor belt, and the right end positioning plate 8 is located on the right side of the cigarette box conveyor belt; at this time, the cigarette box on the conveyor belt can smoothly enter between the left end positioning plate 6 and the right end positioning plate 8, and then the left side positioning motor 9 is started, and the left side positioning motor 9 is driven by the gear 10 and the rack 11. Pull the transverse guide rail 5 and the left end positioning plate 6 to move to one side of the frame base 1, and the left side of the cigarette box is blocked by the left end positioning plate 6 until the left end positioning motor 9 stops running. At this time, the left end positioning plate 6 is fixed to block the left side of the cigarette box; then start the right side positioning motor 12, and the right side positioning motor 12 makes the guide sleeve 7 and the right end positioning plate 8 approach the left end positioning plate 6 through the transmission screw 13 and the nut 14. At this time, the right side of the cigarette box blocked by the right end positioning plate 8 is positioned; in this way, both the left and right sides of the cigarette box are positioned. After the cigarette box is positioned and clamped by the left end positioning plate 6 and the right end positioning plate 8, start the horizontal rotation motor 2, and the cigarette box is carried into the corresponding transportation equipment for loading.

[0040] Furthermore, two limit pressure touch switches 15 are installed on the transverse guide rail 5 , and the two limit pressure touch switches 15 are located between the left end positioning plate 6 and the right end positioning plate 8 .

[0041] As described above, when the front side of the cigarette box simultaneously presses the limit pressure switch 15, it can be determined that the cigarette box has been in place in the moving direction of the conveyor belt. At this time, the left positioning motor 9 can drive the transverse guide rail 5 and the left end positioning plate 6 to position the front end of the cigarette box, and then the right positioning motor 12, the transmission screw 13, the nut 14, the guide sleeve 7 and the right end positioning plate 8 can be used to position the rear end of the cigarette box.

[0044] Furthermore, the horizontal rotation motor 2 and the left positioning motor 9 are worm gear reduction motors or planetary reduction motors.

[0045] Among them, the worm gear reduction motor or planetary reduction motor has a very high reduction ratio and self-locking performance, which can convert the high-speed and small torque of the original motor into a low-speed and large torque. Therefore, the horizontal rotation motor 2 can smoothly and accurately drive the positioned and clamped cigarette box to rotate horizontally; the left positioning motor 9 can drive the transverse guide rail 5 and the left end positioning plate 6 to position the left side of the cigarette box.

[0046] Furthermore, horizontal teeth 18 are provided on the opposite sides of the left-end positioning plate 6 and the right-end positioning plate 8. The horizontal teeth 18 are made of rubber material and have anti-slip and shock-absorbing properties. Therefore, the horizontal teeth 18 can enable the left-end positioning plate 6 and the right-end positioning plate 8 to firmly clamp the cigarette box, preventing one end of the cigarette box from drooping due to gravity during transportation, so that the cigarette box remains positioned in a horizontal position.

[0047] Furthermore, the bottom side of the frame base 1 is provided with forward and backward moving wheels 17. The forward and backward moving wheels 17 can enable the main body of the device to carry the positioned cigarette box to move forward and backward, and cooperate with other conveying mechanisms in an arc shape to realize the loading of the cigarette box.
