Description

Technical Field

[0001] This utility model relates to a double-packet flipping device, belonging to the technical field of tobacco packaging equipment. Background Technology

[0002] As the basic packaging unit for tobacco products, cigarette packs undergo multiple changes in position and shape during subsequent boxing and cartoning processes. For example... Figure 1 As shown in the left figure, the position of the double packet 1 output by the host computer is as shown in the left figure. At this time, the letter A is facing left. It is required that before the double packet 1 enters the slave computer, the position of the double packet 1 be adjusted to the position shown in the right figure. At this time, the letter A is facing left and inverted, which is equivalent to rotating the double packet 1 in the left figure by 180 degrees around its width 100. However, due to the limitations of the position of the double packet 1 output by the host computer and the position of the double packet 1 entering the slave computer, it is not convenient to directly rotate the double packet 1 by 180 degrees around its width 100.

[0003] Chinese patent document CN116280452A discloses a cigarette pack turning mechanism, mainly comprising a turning assembly, a cigarette pack conveying chute, and a cigarette pack feeding conveyor belt. The turning assembly includes a cigarette pack turning shaft, a cigarette pack turning disc, a guide sleeve, a cigarette pack discharging push rod, and cigarette pack retainers. The cigarette pack turning shaft is connected to a cigarette pack turning motor that drives the turning shaft to rotate around its own axis. The cigarette pack turning disc is driven by the turning shaft to rotate around its center. The guide sleeve has guide holes, allowing the cigarette pack discharging push rod to move along the axis of the guide holes. Cigarette pack retainers are located at both ends of the cigarette pack discharging push rod, forming cigarette pack retaining grooves with outer openings and inner insertion ports communicating with the retaining grooves. This mechanism has advantages such as high reliability and strong applicability, improving the automation level of tobacco product production and filling the current technological gap in automatic cigarette pack turning mechanisms applicable to the filling of flip-top carton boxes.

[0004] However, this flipping mechanism can only flip the cigarette pack 180 degrees around its long side, but cannot flip it 180 degrees around its wide side. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a double-package flipping device.

[0006] This utility model is achieved through the following technical solution:

[0007] A double-package flipping device includes a high-side flipping mechanism, a long-side flipping mechanism, and a pushing mechanism. The inlet of the long-side flipping mechanism is connected to the outlet of the high-side flipping mechanism. The pushing mechanism pushes the double-packages that have been flipped in the high-side flipping mechanism to the long-side flipping mechanism and simultaneously pushes the double-packages that have been flipped in the long-side flipping mechanism outward.

[0008] The high-side flipping mechanism includes a base plate, an arc plate A, and an arc plate B. The base plate is provided with a semi-circular arc-shaped support plate. A bushing is provided at the bottom of the base plate. A rotating shaft is rotatably provided inside the bushing. A rotating disk is provided at the upper end of the rotating shaft. The rotating disk is located on the upper side of the bushing and inside the semi-circular arc-shaped support plate. Multiple limiting blocks A are arranged in a circumferential array on the rotating disk. Both arc plates A and B are arranged along the outer arc of the semi-circular arc-shaped support plate. One end of arc plate B is connected to one end of arc plate A. Arc plate A is mounted on the semi-circular arc-shaped support plate by a vertical block.

[0009] The high-side flipping mechanism also includes an arc-shaped height limiting rod, which is connected to the vertical block through a horizontal plate. The semi-circular support plate is provided with height limiting plates on both sides of the feed inlet of the long-side flipping mechanism.

[0010] The long-side flipping mechanism includes a cam divider and a cigarette pack flipping component. The cam divider is equipped with a speed reducer, and the speed reducer is equipped with a motor. The cigarette pack flipping component is located on the output shaft of the cam divider.

[0011] The cigarette pack flipping component includes two rotating upright plates and an arc-shaped limiting plate. The two rotating upright plates are arranged side by side and fixedly mounted on the output shaft of the cam divider. Multiple slots A are evenly distributed on the two rotating upright plates, and each slot A is equipped with a limiting plate. The limiting plate has a slot B, and grooves are formed on both sides of the slot B. A pressure plate is rotatably connected to the groove through a pin. The end of the pressure plate away from the pin is connected to the bottom surface of the groove through a compression spring. The arc-shaped limiting plate is located on the lower side of the two rotating upright plates and is connected to the housing of the cam divider through a mounting block.

[0012] The pushing mechanism includes a support frame and a push-pull rod. The support frame is mounted on the housing of the cam divider and is equipped with a linear bearing. The push-pull rod is slidably connected to the linear bearing and is parallel to the two rotating vertical plates. A push block A is provided in the middle of the push-pull rod, and a push block B is provided at one end of the push-pull rod near the rotating vertical plate. The push block B is located between the two rotating vertical plates.

[0013] It also includes the chassis, with both the high-side flipping mechanism and the long-side flipping mechanism located on the chassis.

[0014] The beneficial effects of this utility model are as follows: the high-side flipping mechanism drives the double package to flip 180 degrees around the high side, and the long-side flipping mechanism drives the double package to flip 180 degrees around the long side, thereby achieving the purpose of flipping the double package around its wide side 180 degrees, so that the position and shape of the double package meet the feeding requirements of the lower machine.

Detailed Implementation

[0023] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0024] like Figures 1 to 7 As shown, the double-packet flipping device of this utility model includes a high-side flipping mechanism 3, a long-side flipping mechanism 5, and a pushing mechanism 4. The inlet of the long-side flipping mechanism 5 is connected to the outlet of the high-side flipping mechanism 3. The pushing mechanism 4 pushes the double-packet 1 that has been flipped in the high-side flipping mechanism 3 to the long-side flipping mechanism 5, and simultaneously pushes the double-packet 1 that has been flipped in the long-side flipping mechanism 5 outward. In use, the high-side flipping mechanism 3 drives the double-packet 1 to flip 180 degrees around the high side 102. The position of the double-packet 1 after flipping is as follows. Figure 7 As shown in the middle figure; the double package 1 is rotated 180 degrees around the long side 101 by the long side flipping mechanism 5. The position of the double package 1 after the flip is completed is as follows. Figure 7 As shown in the right figure; this achieves the purpose of rotating the double package 1 180 degrees around its wide side 100, so that the position and shape of the double package 1 meets the feeding requirements of the lower-level machine. Figure 2 As shown, the pushing mechanism 4 simultaneously pushes the double package 1, which has already been flipped in the high-side flipping mechanism 3 and the long-side flipping mechanism 5, a certain distance to the right.

[0025] The high-side flipping mechanism 3 includes a base plate 30, an arc plate A32, and an arc plate B33. A semi-circular arc support plate 38 is provided on the base plate 30. A bushing 39 is provided at the bottom of the base plate 30. A rotating shaft 310 is rotatably provided inside the bushing 39. A rotating disk 35 is provided at the upper end of the rotating shaft 310. The rotating disk 35 is located on the upper side of the bushing 39 and on the inner side of the semi-circular arc support plate 38. Multiple limiting blocks A36 are arranged in a circumferential array on the rotating disk 35. The arc plates A32 and B33 are both arranged along the outer arc of the semi-circular arc support plate 38. One end of the arc plate B33 is connected to one end of the arc plate A32. The arc plate A32 is mounted on the semi-circular arc support plate 38 by a stand block 311. In use, bushing 39 and base plate 30 are mounted on housing 2 via bracket B (not shown in the figure). Housing 2 also houses geared motor A, and the output shaft of geared motor A is connected to the lower end of rotating shaft 310. Arc plate B33 is connected to housing 2 via bracket A312.

[0026] The high-side flipping mechanism 3 also includes an arc-shaped height limiting rod 31, which is connected to the vertical block 311 via a horizontal plate. The semi-circular support plate 38 is provided with height limiting plates 34 on both sides of the feed inlet of the long-side flipping mechanism 5.

[0027] Specifically, such as Figure 3 and Figure 4 As shown, the host computer will display the positional configuration as follows: Figure 7 As shown in the left figure, after the double package 1 is pushed to the high-side flipping mechanism 3, the geared motor A drives the rotating disk 35 to rotate counterclockwise. During this process, the bottom surface of the double package 1 is supported by the semi-circular support plate 38, and the double package 1 is limited in the radial direction by the arc plate A32 and the arc plate B33, and the double package 1 is limited in the axial direction by the arc-shaped height limiting rod 31. After the double package 1 is flipped 180 degrees around its high side 102, its position is as follows. Figure 7 As shown in the middle figure. During the process of the pushing mechanism 4 pushing the double package 1, which has been flipped in the high-side flipping mechanism 3, into the long-side flipping mechanism 5, the double package 1 is limited in the axial direction of the rotating disk 35 by the height limiting plate 34. The main shaft of the geared motor A performs intermittent rotational motion.

[0028] The long-side flipping mechanism 5 includes a cam divider 51 and a cigarette pack flipping component. The cam divider 51 is equipped with a reducer 52, and the reducer 52 is equipped with a motor 53. The cigarette pack flipping component is located on the output shaft of the cam divider 51. In use, the cam divider 51 is mounted on the housing 2 via a base 50.

[0029] The cigarette pack flipping component includes two rotating upright plates 54 and an arc-shaped limiting plate 57. The two rotating upright plates 54 are arranged side by side and fixedly mounted on the output shaft of the cam divider 51. Multiple slots A are evenly distributed on each of the two rotating upright plates 54, and a limiting plate 55 is provided at each slot A. A slot B550 is provided on each limiting plate 55. Grooves are provided on both sides of slot B550. A pressure plate 56 is rotatably connected to the groove via a pin. The end of the pressure plate 56 away from the pin is connected to the bottom surface of the groove via a compression spring. The arc-shaped limiting plate 57 is located below the two rotating upright plates 54 and is connected to the housing of the cam divider 51 via a mounting block 58. In use, the pressure plate 56 clamps the double pack 1 that has entered the slot B550 under the spring force of the compression spring (not shown in the figure).

[0030] Specifically, motor 53 drives two rotating vertical plates 54 to rotate counterclockwise via reducer 52 and cam divider 51. During this process, the double package 1 is limited by the slots B550 on the two corresponding limiting plates 55, and the double package 1 is clamped by the pressure plate 56 inside the slots B550. At the same time, the double package 1 is limited radially by the arc-shaped limiting plate 57. After the double package 1 rotates 180 degrees around its long side 101, its position is as follows. Figure 7 As shown in the right figure, the main shaft of motor 53 rotates intermittently.

[0031] The pushing mechanism 4 includes a support frame 40 and a push-pull rod 42. The support frame 40 is mounted on the housing of the cam divider 51 and has a linear bearing 41. The push-pull rod 42 is slidably connected to the linear bearing 41 and is parallel to the two rotating upright plates 54. A push block A43 is provided in the middle of the push-pull rod 42, and a push block B44 is provided at one end of the push-pull rod 42 near the rotating upright plate 54, with the push block B44 located between the two rotating upright plates 54. In use, the end of the push-pull rod 42 away from the rotating upright plate 54 is connected to a linear motor (not shown in the figure). The linear motor is mounted on the housing 2 via a bracket C (not shown in the figure), and the linear motor drives the push-pull rod 42 to move linearly back and forth. When the push-pull rod 42 moves to the right, it drives the push block A43 to push the double package 1, which has been flipped in the high-side flipping mechanism 3, into the long-side flipping mechanism 5. At the same time, it drives the push block B44 to push the double package 1, which has been flipped in the long-side flipping mechanism 5, outward.

[0032] It also includes chassis 2, with the high-side flipping mechanism 3 and the long-side flipping mechanism 5 both located on chassis 2.
