[0033] In the description of this embodiment, terms such as "upper," "lower," "right," and "left" are used to refer to positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0034] The following is based on the attached Figure 1 To the attached Figure 4 The box-shaped member turning device provided by the present invention is described below. In this embodiment, the box-shaped member turning device is primarily installed on a cigarette packaging production line, and is used to turn a flat cigarette box 109 90 degrees, feeding it into a subsequent packaging device in the form of a vertical cigarette box 107, thereby packaging it in a "ten-pack vertical row" format to form a carton. In some embodiments, the box-shaped member turning device can also be used to turn a carton entirely, which is not specifically limited in the present invention.

[0035] Specifically, in this embodiment, the box-shaped member turning device mainly includes a first conveying mechanism, a limiting bracket, a rotating support plate 110, and a second conveying mechanism. The first conveying mechanism is used to transport the cigarette boxes in a horizontal position, that is, to lay the cigarette boxes 109 flat. The limiting bracket is fixedly arranged and located at the end of the first conveying mechanism, and an arc-shaped channel is formed inside the limiting bracket. Specifically, the arc-shaped channel is a channel that is approximately a quarter of a circle arc around a preset axis (for convenience of description, the preset axis is defined as the central axis in the present invention), and its internal cross-section can be square. The arc-shaped channel allows the cigarette boxes to pass through and prevents accidental displacement such as falling during the turning process, which is conducive to improving the turning efficiency. The two ends of the limiting bracket are respectively provided with a first opening and a second opening. The opening directions of the first opening and the second opening are both arranged in a horizontal direction and are both connected to the above-mentioned arc-shaped channel. When the cigarette box moves to the end of the first conveying mechanism, it can enter the arc-shaped channel from the first opening and turn 90 degrees when passing through the arc-shaped channel. Then, it leaves the limiting bracket from the second opening and enters the second conveying mechanism. The first conveying mechanism and the second conveying mechanism can be a conveyor belt or a clamping belt 112. As long as they can transport the cigarette boxes, they are within the scope of protection of the present invention.

[0036] The rotating support plate 110 is arranged on one side of the arc-shaped channel close to the central axis and can rotate around the central axis. The end of the limiting bracket provided with the first opening is also provided with a third opening, and the opening direction of the third opening is set in a vertically downward direction. The end of the rotating support plate 110 away from the central axis is provided with a supporting portion, which is used to abut and push the cigarette box. When the rotating support plate 110 rotates to the end of the first conveying mechanism, the supporting portion is exactly located at the third opening, and the supporting portion and the first conveying mechanism are at the same height, so that the cigarette box can be smoothly moved from the first conveying mechanism to the supporting portion and simultaneously enter the arc-shaped channel through the first opening.

[0037] The limiting bracket is also provided with a first groove, one end of the first groove being connected to the third opening along the extension direction of the arc-shaped channel, and the other end being connected to the second opening. Furthermore, along the radial direction of the arc-shaped channel, the first groove is connected to the arc-shaped channel, so that when the rotating support plate 110 rotates around the central axis, it can be inserted into the arc-shaped channel along the radial direction of the arc-shaped channel. In this way, the supporting portion can move along the arc-shaped channel, thereby pushing the cigarette box to be transported and flipped along the arc-shaped channel within the limiting bracket, and finally leaving the arc-shaped channel from the second opening in a vertical posture, that is, leaving the arc-shaped channel in the posture of a vertical cigarette box 107. The second conveying mechanism is arranged at one end of the limiting bracket away from the first conveying mechanism, and can receive the cigarette box that leaves the limiting bracket from the second opening and convey the cigarette box to the downstream device.

[0038] At the same time, the rotating support plate 110 can also move or rotate so that the distance between the supporting portion and the central axis can be adjusted. When the supporting portion moves away from the central axis, the distance between the supporting portion and the central axis increases, and the supporting portion can extend into the arc-shaped channel to push the cigarette box to move. When the supporting portion moves toward the central axis, the distance between the supporting portion and the central axis decreases, and interference between the supporting portion and the second conveying mechanism can be avoided.

[0039] For example, when the rotating pallet 110 rotates to the second opening, the rotating pallet 110 can maintain its movement around the central axis while rotating in a direction close to the central axis, thereby moving the supporting portion in a direction away from the second conveying mechanism. This allows the supporting portion to avoid collision with the second conveying mechanism or the cigarette boxes when the rotating pallet 110 rotates around the central axis, thereby ensuring the normal transportation of the cigarette boxes. When the rotating pallet 110 continues to rotate around the central axis and moves away from the second conveying mechanism, the rotating pallet 110 rotates in a direction away from the central axis, so that when the rotating pallet 110 rotates to the first conveying mechanism, the supporting plate remains horizontal, thereby continuing to receive the cigarette boxes and pushing the cigarette boxes to be transported and flipped within the arc-shaped channel.

[0040] The above-mentioned box-shaped member turning device can transform horizontally transported cigarette boxes into a vertical position, thereby conveniently realizing vertical packaging in the subsequent packaging device. At the same time, the rotating support plate 110 can not only rotate about the central axis to realize the transportation of cigarette boxes and cooperate with the limit bracket to realize the stable turning of cigarette boxes, but also can swing itself to avoid collision between the rotating support plate 110 and surrounding objects, so that the rotation speed about the central axis is significantly increased, thereby greatly improving the turning efficiency and ensuring the production efficiency of cigarettes.

[0041] More specifically, in this embodiment, the box-shaped member flipping device also includes a first transmission assembly, which includes a transmission shaft 117, a wheel cover plate 111, and a wheel body 104. The transmission shaft 117, the wheel cover plate 111, the wheel body 104, and the arc-shaped channel are all coaxially arranged along the above-mentioned central axis. The transmission shaft 117, the wheel cover plate 111, and the wheel body 104 are fixedly connected by a first flange 113 and a second flange 114. The transmission shaft 117 is provided with a toothed pulley 101 (which can be a gear, sprocket, or other mechanism as long as it can input power, it falls within the scope of protection of the present invention) at one end away from the wheel cover plate 111. It can be connected to a drive member such as a transmission belt and a motor. Under the action of the drive member, the transmission shaft 117 can rotate to drive the wheel cover plate 111 and the wheel body 104 to rotate. The rotating support plate 110 is arranged on the wheel cover plate 111. When the wheel cover plate 111 rotates, the rotating support plate 110 can rotate around the central axis, thereby pushing and conveying the cigarette box.

[0042] like Figure 1 、 Figure 2 As shown, in this embodiment, four rotating support plates 110 are connected to the wheel cover plate 111. That is, each rotation of the wheel cover plate 111 can flip eight cigarette boxes, thereby greatly improving the flipping efficiency. For example, in this embodiment, the flipping efficiency of the box-shaped member flipping device can reach more than 500 packs / minute. Of course, in some other embodiments, other numbers of rotating support plates 110 can also be set on the wheel cover plate 111, such as 2, 3, or more, and this is not specifically limited in the present invention.

[0043] Continue to refer to Figure 1 、 Figure 2 As shown, the box-shaped member flipping device further includes a second transmission assembly, which includes a first gear shaft 105. The wheel cover plate 111 has a through hole. The first gear shaft 105 is rotatably inserted into the wheel cover plate 111 through the through hole. One end of the first gear shaft 105 passes through the wheel cover plate 111 and is fixedly connected to the end of the rotating support plate 110 away from the supporting portion. When the first gear shaft 105 rotates, the rotating support plate 110 can rotate, thereby changing the distance between the supporting portion and the central axis.

[0044] Furthermore, the second transmission assembly also includes a disc cam 102, a second gear shaft 106, a connecting rod 115 and a roller 116. The disc cam 102 is fixedly arranged and is located on the side of the wheel cover 111 away from the rotating support plate 110. The disc cam 102 has a second groove 103, and the roller 116 is inserted into the second groove 103 and movably arranged along the second groove 103. The second gear shaft 106 is rotatably connected to the wheel cover 111 and the wheel body 104 through a channel bearing, and the other end is inserted into the second groove 103 and movably arranged along the second groove 103. The connecting rod 115 is connected between the second gear shaft 106 and the roller 116, that is, the two ends of the connecting rod 115 are respectively inserted and connected between the second groove 103 through the roller 116 and the second gear shaft 106. The second gear shaft 106 is arranged parallel to the first gear shaft 105 , and both the second gear shaft 106 and the first gear shaft 105 are provided with gear parts, and the two are connected by meshing transmission via the gear parts.

[0045] Second gear shaft 106 has more teeth than first gear shaft 105, acting as an amplification mechanism. Second gear shaft 106 drives roller 116 on connecting rod 115 to rotate within second groove 103 of disc cam 102. The preset profile of second groove 103 acts on roller 116, which, through connecting rod 115, drives second gear shaft 106 to swing in the opposite direction by an angle β. After amplification, first gear shaft 105 swings in the opposite direction by an angle а, which in turn drives rotating support plate 110 to swing in the opposite direction by the same angle. а = kβ, where k > 1, and k represents the ratio of the number of teeth on the second gear shaft to the number of teeth on the first gear shaft. This amplification mechanism aims to reduce the amplitude of sudden changes in the profile of second groove 103 of disc cam 102, increase the profile curvature, and mitigate the inertia and vibration of roller 116 during high-speed rotation within second groove 103, ensuring smooth and high-speed cigarette pack flipping.

[0046] like Figure 4 As shown, in this embodiment, the second groove 103 includes a first portion and a second portion. The first portion, segment EF, has a base arc profile (near rest profile), while the second portion has a different arc profile from the first portion and is sequentially divided into a push profile segment FG, a far rest profile segment GH, and a return profile segment HE. When the wheel cover plate 111 and the wheel body 104 rotate under the drive of the transmission shaft 117, the second gear shaft 106 rotates along with the wheel cover plate 111 and the wheel body 104, causing the end of the second gear shaft 106 and the roller 116 to move along the second groove 103. In the push stroke profile FG section, the connecting rod 115 swings in the opposite direction around the second gear shaft 106, causing the second gear shaft 106 and the first gear shaft 105 to rotate in the opposite direction around their own axes in succession, thereby causing the rotating support plate 110 to rotate at a preset angle when it rotates to a preset position; in the far rest profile GH section, the connecting rod 115 does not swing in the opposite direction; in the return stroke profile HE section, the connecting rod 115 swings in the forward direction. By properly setting the profile shape of the second part, it is possible to ensure that when the rotating support plate 110 rotates to the second opening, it can maintain its movement around the central axis while swinging in a direction close to the central axis, thereby moving the supporting portion in a direction away from the second transmission mechanism. Furthermore, after the rotating support plate 110 continues to rotate around the central axis and moves away from the second conveying mechanism, the rotating support plate 110 rotates in a direction away from the central axis, so that when the rotating support plate 110 rotates to the first conveying mechanism, the supporting plate remains horizontal, thereby continuing to receive the cigarette box and pushing the cigarette box to be transported and flipped in the arc channel.

[0047] Furthermore, in this embodiment, the box-shaped component flipping device also includes a wheel body 104, which is fixedly connected to the side of the wheel cover plate 111 away from the rotating support plate 110 and is fixedly connected to the transmission shaft 117 through a flange. Specifically, the transmission shaft 117 is arranged through the wheel body 104, and a first flange 113 and a second flange 114 are processed on the transmission shaft 117. The first flange 113, the second flange 114, the wheel cover plate 111, and the wheel body 104 are fixedly connected by positioning pins and screws, so that the transmission shaft 117 can drive the wheel cover plate 111 and the wheel body 104 to rotate synchronously. A receiving cavity is defined between the wheel body 104 and the wheel cover plate 111, and the transmission shaft 117, the first gear shaft 105, and the second gear shaft 106 are arranged through the wheel body 104, and the gear parts of the first gear shaft 105 and the second gear shaft 106 are accommodated in the receiving cavity, thereby achieving a good sealing effect and lubrication protection effect on the gear parts.

[0048] like Figure 3 As shown, in this embodiment, the limiting bracket includes a bracket plate 108 and guide bars 201 disposed on both sides of the bracket plate 108. The bracket plate 108 and the two guide bars 201 together define the aforementioned arc-shaped channel, and the two guide bars 201 define the aforementioned first groove. Preferably, the two guide bars 201 are further provided with brushes 202 on the side facing the cigarette box, so that the brushes 202 can be used to limit and abut the cigarette box on opposite sides of the arc-shaped channel. This not only reduces the resistance and collision encountered by the cigarette box when moving within the arc-shaped channel, but also limits the movement path of the cigarette box, facilitating stable and efficient movement and flipping of the cigarette box.
