Description

Technical Field

[0001] The present invention belongs to the technical field of packaging equipment, and in particular relates to an automatic package turning and transferring device for packaging boxes. Background Art

[0002] Packaging boxes are the primary form of product packaging. Within a packaging production line, these boxes must be adjusted between different workstations. For example, in a tobacco packaging machine's automated cigarette pack transfer line, cigarette packs must transition from horizontal to vertical between two workstations.

[0003] Currently, automated devices for flipping cigarette packs use a step-by-step process of flipping and linear translation to automatically flip and transfer cigarette packs. The device flips the angle of two stacked cigarette packs in a single round-trip motion. This type of automatic cigarette pack flipping device has the following disadvantages:

[0004] 1. The device is large in size and has a large movement space. The flip device requires the production line to have a sufficiently large installation and working space, has high requirements for the installation environment, and is not conducive to the compact structure of the production line.

[0005] 2. The device has a loud working noise. The device has a large working range and many steps, making it difficult to effectively reduce the working noise.

[0006] 3. Low working efficiency. This drawback is the most prominent shortcoming of the current cigarette pack turning device. The step-by-step action and reciprocating working mode limit the working efficiency of the existing device. At present, the maximum working efficiency that can be achieved by the most efficient cigarette pack turning device is 230 times / minute. Summary of the Invention

[0007] In view of the problems existing in the prior art, the present invention provides a packaging box turning and moving device that solves the problems of low working efficiency, high noise and large working movements of the current packaging box turning devices.

[0008] The present invention is implemented as follows: a packaging box turning and moving device includes a frame, which is characterized by comprising:

[0009] A fixed shaft, the fixed shaft being fixed on the frame, and the axis of the fixed shaft being arranged horizontally;

[0010] A flat groove-shaped convex disc, the flat groove-shaped convex disc is fixed to the end of the fixed shaft, and the front end surface of the flat groove-shaped convex disc has a groove;

[0011] A power input sleeve shaft, the power input sleeve shaft is sleeved on the fixed shaft, and the power input sleeve shaft and the fixed shaft are coaxial;

[0012] A turntable, the turntable being fixed to the end of the power input sleeve shaft, the turntable being coaxial with the power input sleeve shaft, the turntable having an eccentric shaft hole, a guide hole being provided on the back side of the turntable opposite to the groove of the planar groove-shaped convex disc, the axis of the guide hole being parallel to the disc surface of the turntable;

[0013] A turning shaft, the turning shaft being installed in the eccentric shaft hole of the rotating disk, the turning shaft being rotatable around its own axis, the rear end of the turning shaft being opposite to the flat groove-shaped convex disk;

[0014] A movable rod is fitted in the guide hole of the turntable, a groove roller is mounted on the movable rod, and the groove roller is fitted in the groove of the flat groove convex disc. The movable rod moves along its own axis under the guidance of the groove. The side of the movable rod is a rack portion, and the rear end of the flip shaft is equipped with a flip gear meshing with the rack portion;

[0015] A box body bracket is installed on the outer end of the flip shaft and is used for supporting card packaging boxes.

[0016] In the above technical solution, preferably, the power input sleeve is mounted on the frame through a bearing, the fixed shaft is arranged on the inner side of the power input sleeve, a bearing is assembled between the fixed shaft and the power input sleeve, and the rear end of the fixed shaft is fixed to the frame.

[0017] In the above technical solution, preferably, the front end of the power input sleeve is fixed with a cylindrical flip head, the rear end cover of the flip head is fixed to the power input sleeve, the front end cover of the flip head is installed with the turntable, the inner side of the flip head is a cylindrical cavity, and the flat groove-shaped convex disc is arranged in the cylindrical cavity.

[0018] In the above technical solution, preferably, a guide block is fixed on the inner end face of the turntable, the guide hole is provided on the guide block, the guide block is provided with a notch, the flip gear at the rear end of the flip shaft is located in the notch and engages with the rack portion of the movable rod.

[0019] In the above technical solution, preferably, a fixed end sleeve is fixedly installed on the end of the movable rod, and the fixed end sleeve is installed with a groove roller that is adapted to the groove of the plane grooved convex disk.

[0021] The advantages and effects of the present invention are:

[0022] 1. Compact structure. In this invention, the box turning mechanism has an angle compensation function. After the turntable turns 180°, the turning axis can be driven by a movable rod to rotate a certain angle to compensate for the circumferential angle, allowing the turning axis to achieve a 90° angle change. This allows the box body bracket to achieve horizontal movement and complete a 90° angle flip, significantly reducing the movement stroke. Compared with traditional devices, the structural size and movement range of this device are reduced, the equipment structure is closer and more compact, and the requirements for the installation environment are reduced.

[0023] 2. The workstation is stable and the working noise is low. The movement amplitude of this device is greatly reduced compared with the traditional device. After increasing the movement frequency of the device, the smaller movement amplitude greatly reduces the centrifugal force received by the packaging box, ensuring the stability of the packaging box during the transfer and flipping process; on the other hand, the smaller movement amplitude and more compact mechanical structure have a very significant effect on improving the working noise of the equipment.

[0024] 3. High work efficiency. The turntable in this device only needs to rotate half a circle to complete the transfer and flip of the packaging box. With the turntable set up in a dual-station structure, the turntable completes the transfer and flipping of the packaging box twice in one rotation. Compared with traditional devices, the work efficiency of this device is significantly improved, and can achieve 400 packaging box transfers and flips per minute. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] To address the problems of low efficiency, high noise, and large movements in current packaging box flipping devices, the present invention provides an automatic packaging box flipping and transfer device. This device operates with low noise, is stable, has a compact and reliable structure, and has high efficiency. To further illustrate the structure of the present invention, a detailed description is provided below with reference to the accompanying drawings:

[0035] See also Figure 1-7 A packaging box turning and moving device includes a frame, a fixed shaft 1, a flat groove convex plate 2, a power input sleeve shaft 3, a turntable 4, a turning shaft 5, a movable rod 6, and a box body bracket 7.

[0036] The fixed shaft 1 is fixed to the frame, and the axis of the fixed shaft 1 is set horizontally. The fixed shaft 1 is a cylindrical shaft rod, and its installation and working state is fixed. Specifically, a keyway is machined at one end, and this end is fitted with a shaft sleeve through the key sleeve. This shaft sleeve is fixed to the frame with fasteners, thereby achieving the fixed installation of the fixed shaft 1.

[0037] A flat grooved flange 2 is fixed to the end of the fixed shaft 1. Its front end features a groove. This flange 2 is a flat grooved cam structure that operates in a stationary state. In this embodiment, the front end of the fixed shaft 1 has an integral flange, to which the flange is secured using a bolt and nut assembly. The end of the fixed shaft 1 on which the flat grooved flange 2 is mounted faces the station where the packaging box is flipped and transferred.

[0038] The power input sleeve 3 is sleeved on the fixed shaft 1, and the power input sleeve 3 is coaxial with the fixed shaft 1. In this embodiment, specifically, the power input sleeve 3 has a central through hole, and the fixed shaft 1 is set in the central through hole of the power input sleeve 3. A bearing is set between the inner wall of the power input sleeve 3 and the outer wall of the fixed shaft 1 to achieve the installation of the power input sleeve 3 coaxial with the fixed shaft 1 and rotatable around its own axis. A mounting hole for mounting the power input sleeve 3 is provided on the frame, and a mounting shaft is assembled between the outer wall of the power input sleeve 3 and the mounting hole of the frame for mounting the power input sleeve 3, and the power input sleeve 3 can rotate around its own axis. The front end of the fixed shaft 1 automatically extends in front of the power input sleeve 3 and this end fixes the above-mentioned flat groove-shaped convex disc 2.

[0039] The turntable 4 is fixed to the end of the power input sleeve 3 and is coaxial with the power input sleeve 3. Specifically, in this embodiment, a cylindrical tilting head 8 is fixed to the front end of the power input sleeve 3. The tilting head 8 comprises a circular rear end cap 8-1 with a central through-hole, a cylindrical sidewall 8-2, and a front end cap 8-3 with two through-holes. The tilting head 8 is driven for rotation by the power input sleeve 3. An integral flange is provided at the front end of the power input sleeve 3, to which the rear end cap 8-1 is fixed. The fixed shaft 1 extends from the center hole of the rear end cap 8-1 to the front end cap 8-1. The front end cap 8-3 of the tilting head 8 is mounted with the turntable 4. The turntable 4 and the front end cap 8-3 have two corresponding through-holes for mounting the tilting shaft 5. The turntable 4 is fixed to the front end cap 8-3 via bolts. The inner side of the tilting head 8 is formed by the rear end cap 8-1, the cylindrical sidewall 8-2, and the front end cap 8-3, forming a cylindrical cavity. The flat groove-shaped protrusion 2 is located within this cylindrical cavity.

[0040] The turntable 4 has an eccentric shaft hole 4-1, which is a through-hole machined into the turntable 4 and corresponds to the front end cover 8-3. A guide hole is provided on the back of the turntable 4, opposite the groove of the flat grooved flange 2. The axis of the guide hole is parallel to the surface of the turntable 4. In this embodiment, the front end cover 8-3 of the flip head 8 can serve as the back structure of the turntable 8. A guide block 9 is fixed to the back of the front end cover 8-3 of the flip head 8. The guide hole is provided in the guide block 9. The guide block 9 has a handle and a hole machined into it and is fixed to the back of the front end cover 8-3 by bolts, located in the cylindrical cavity.

[0041] The tilt shaft 5 is mounted in the eccentric shaft hole 4-1 of the turntable 4. The tilt shaft 5 is rotatable about its own axis, with the rear end of the tilt shaft 5 facing the flat groove-shaped convex plate 2. Specifically, the tilt shaft 5 is rotatable about its own axis and is fitted into the eccentric shaft hole 4-1 of the turntable 4 via a bearing. The rear end of the tilt shaft 5 extends into the cylindrical cavity of the tilt head 8.

[0042] The movable rod 6 is fitted into the guide hole of the turntable 4. The movable rod 6 is equipped with a grooved roller, which is fitted into the groove of the plane grooved convex disc 2. The movable rod 6 is movable along its own axis under the guidance of the groove. Specifically, the movable rod 6 is a cylindrical rod, and a through hole is machined on the guide block 9. The two ends of the through hole are adapted to the diameter of the movable rod 6 as described in the guide hole. Under the action of the guide hole, the movable rod 6 can be movable along its axis. In this embodiment, the end of the movable rod 6 is fixedly installed with a fixed end sleeve 10, which is directly fixed to the end of the movable rod 9 with a screw. The fixed end sleeve 10 is equipped with a grooved roller that is adapted to the groove of the plane grooved convex disc 2. The other end of the movable rod 9 is gap-fitted with a movable end sleeve 11, which is equipped with another grooved roller that is adapted to the groove of the plane grooved convex disc 2. The grooved roller is fitted into the groove of the plane grooved convex disc 2. The combination method of the grooved roller and the groove of the plane grooved convex disc 2 and the linkage principle are well-known technologies in the mechanical field. When the turntable 4 drives the guide block 9 to rotate, the groove roller moves in the groove of the flat groove convex plate 2, and the distance between the end of the movable rod 6 and the center of the turntable 4 changes accordingly according to the spatial curve of the groove, thereby realizing the coordinated action of the movable rod 6 moving along its axis while the turntable 4 rotates.

[0043] The side of the movable rod 6 is formed by a rack portion 6-1, and the rear end of the tilt shaft 5 is equipped with a tilt gear 12 that meshes with the rack portion 6-1. Specifically, the rack portion 6-1 is a toothed shape machined into the side of the movable rod 6. A notch 9-1 is provided on the outer side of the guide block 9, connecting to the center of the through-hole of the guide block 9. The rack portion 6-1 of the movable rod 6 is exposed through this notch. The tilt gear 12 at the rear end of the tilt shaft 5 is located within the notch and meshes with the rack portion 6-1 of the movable rod 6. The meshing connection between the tilt gear 12 and the rack portion 6-1 converts the linear motion of the movable rod 6 into a circumferential angular change of the tilt shaft 5. Therefore, during the rotation of the turntable 4, the tilt shaft 5 performs independent angular compensation simultaneously. By calculating and designing the groove trajectory parameters of the planar grooved cam 2 and the meshing ratio of the rack portion and the tilt gear, after the turntable rotates 180°, the tilt shaft 5 achieves a 90° rotation through its own reverse rotation compensation.

[0044] The box support 7 is mounted on the outer end of the tilting shaft 5 and serves as a carrier for the tilting movement of the box. The box support 7 can be constructed similarly to conventional boxes. In this embodiment, the box support 7 comprises a bottom support 7-1 and side supports 7-2. The bottom support 7-1 and side supports 7-2 can be integrally formed. A slot is formed between the bottom support 7-1 and the side supports 7-2 to support the box. When the slot is horizontal, the left side of the slot is an opening for inserting a horizontally positioned box. The bottom support 7-1 has two slits opening from the left side. These slots are located in the swinging path of the box pusher arm 2-6 of the box ejection mechanism 2, ensuring that the swinging box pusher arm 2-6 can move the box supported by the box support 7 and eject the upright box from the box support. In this embodiment, to ensure that the box support 7 securely supports the box, metal springs with inwardly curved projections are installed on both sides of the box support 7 to clamp the sides of the box.

[0045] The box body bracket 7, flip shaft 5, flip gear 12, movable rod 6, fixed end sleeve 10, movable end sleeve 11, and grooved rollers comprise a flip assembly. Two flip assemblies are positioned on either side of the center of the turntable 4 of this flipping mechanism 1. Specifically, two eccentric shaft holes 4-1 are symmetrically positioned on either side of the turntable 4, creating a dual-station flipping device. The two box body brackets 7 of the two flip assemblies are positioned horizontally, with a 90° angle difference. The box body bracket of the left flip assembly is horizontal, while the box body bracket of the right flip assembly is vertical. After the turntable flips 180°, the two box body brackets 7 interchange positions and achieve a 90° angle change by rotating clockwise around the center of the turntable and compensating for the angle of their own flip axes, thereby completing a single flip movement of the packaging box.

[0046] After the packaging box moves to the upright state, the packaging box is pushed down from the box body bracket by a box-pushing mechanism provided on the side of the packaging box turning and moving device. The box-pushing mechanism can be a lever driven by an independent motor. The output shaft of the driving motor rotates one circle, and the lever is controlled to rotate once to realize one box-pushing.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.
