Description

Technical Field

[0001] The invention relates to a packaging box overturning roller conveyor. Background Art

[0002] In industries like warehousing and logistics, and food processing, palletizing and stacking packaged goods is essential for storage and management. Regardless of the palletizing method used, the boxes must be adjusted to the proper stacking position before entering the palletizing station. Placing the boxes upright or laying them down is essential preparatory work, necessitating the installation of a tilting conveyor before the station. Currently, the tilting mechanism of the widely used tilting conveyors is a fixed structure, meaning that the boxes must be turned over as they pass through this conveyor line. If other sizes of boxes do not require turning during palletizing, a separate conveyor line must be set up to bypass the tilting conveyor. This not only increases system costs but also makes system planning more difficult. Summary of the Invention

[0003] In order to solve the problems in the prior art, the present invention provides a packaging box turnover roller conveyor.

[0004] The technical solution provided by the present invention is:

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] A packaging box turning roller conveyor, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 Shown, including:

[0019] The flip mechanism is provided with an inner rotating shaft 1, an outer rotating shaft 2, an inner rotating shaft flap 3, an outer rotating shaft flap 4, a clutch device 5 and a drive motor 6. The drive motor 6 is used to drive the inner rotating shaft 1 or the outer rotating shaft 2 to rotate. In this patent, it is arranged at one end of the inner rotating shaft 1. The end of the inner rotating shaft 1 is provided with a keyway that cooperates with the drive motor 6, so that the drive motor drives the inner rotating shaft 1 to rotate. The inner rotating shaft 1 is arranged in the outer rotating shaft 2 and can rotate relative to the outer rotating shaft 2. The main body of the outer shaft 2 is provided with an opening that allows the inner shaft 1 to be exposed. The openings are provided with two in a circumferential direction. The inner shaft flaps 3 are provided above a circumferential direction and are arranged on the same straight line. The inner shaft flaps 3 are provided on the inner shaft 3 and extend from the openings. The outer shaft flaps 4 are also provided with two and are arranged on the same straight line. At the same time, the outer shaft flaps 4 are fixed on the outer shaft 2. The opening is configured so that when the inner shaft rotates 1, the inner shaft flaps 3 can move to be parallel to the outer shaft flaps 4 and to be perpendicular to the outer shaft flaps 4. The other ends of the inner shaft 1 and the outer shaft 2 are provided with a bayonet, wherein the end of the inner shaft 1 is configured as a cross bayonet and the end of the outer shaft 2 is configured as a straight bayonet. The depth of the straight bayonet of the outer shaft 2 is greater than the cross bayonet of the inner shaft 1, ensuring that the inner shaft 1 and the outer shaft 2 can be simultaneously combined through the pin 10 of the clutch device 5. The clutch device 5 is used to relatively engage or disengage the inner rotating shaft 1 and the outer rotating shaft 2. The bayonet is configured to relatively fix the inner rotating shaft 1 and the outer rotating shaft 2 via the clutch device when the inner rotating shaft flap 3 and the outer rotating shaft flap 4 are parallel, and relatively fix the inner rotating shaft 1 and the outer rotating shaft 2 when the inner rotating shaft flap 3 and the outer rotating shaft flap 4 are perpendicular.

[0020] The conveying rollers 7 are arranged between the inner rotating shaft flap 3 and the outer rotating shaft flap 4 and on the outside of the inner rotating shaft flap 3 and the outer rotating shaft flap 4. There are multiple conveying rollers, which are divided into long rollers and short rollers. The conveying rollers are horizontally arranged inside the frame. The long rollers are powered and are arranged at both ends of the frame to drive the adjacent short rollers. The short rollers are arranged in three rows, and the distance between two adjacent rows is greater than the width of the inner rotating shaft flap 3 and the outer rotating shaft flap 4, and are used to place the inner rotating shaft flap 3 and the outer rotating shaft flap 4 between the two rows. In addition, the conveying rollers 7 leave a gap in the middle of the frame for placing the outer rotating shaft 2 of the flipping mechanism.

[0021] The frame is used to configure the conveying roller 7 and the turning mechanism. The frame is configured on the ground and is the main frame of the equipment, providing an installation position for other mechanisms. The frame is composed of profiles to form a frame structure.

[0022] The clutch device 5 includes a cylinder 8, a sleeve 9, a pin 10, a rotating bearing 11, a connector 12, and a retaining ring 13. The telescopic rod of the cylinder 8 is fixed to the connector 12, and the sleeve 9 is rotatably mounted on the connector 12 via the rotating bearing 11. The sleeve 9 is provided with a pin hole, in which the pin 10 is fixed. The pin 10 is arranged on the diameter of the sleeve 9. The sleeve 9 can be mounted on the end of the outer rotating shaft 2, and the pin 10 can be inserted into the bayonet holes at the ends of the inner rotating shaft 1 and the outer rotating shaft 2 to achieve relative engagement or separation of the inner rotating shaft 1 and the outer rotating shaft 2. The retaining ring 13 is used to secure the pin 10 to the sleeve 9. When the sleeve 9 is mounted on the outer rotating shaft 2, the pin 10 is positioned in the slot of the outer rotating shaft 2 and can slide in the slot. At this time, the outer rotating shaft 1 and the inner rotating shaft 2 are separated. The connector 12 is attached to the sleeve 9 via the rotating bearing 11, ensuring that the connector 12 does not rotate with the sleeve 9 during operation of the tilting mechanism. The cylinder 8 is fixed to the frame and is coaxial with the outer shaft 1 and the inner shaft 2. The piston rod of the cylinder 8, connected to the connector 12, can push the sleeve 9 to slide on the outer shaft 2. The stroke of the cylinder 5 must be greater than the depth of the slot on the outer shaft 2.

[0023] The inner shaft 1 has two pairs of inner shaft flaps 3, both arranged on the same plane. The outer shaft 2 has two pairs of outer shaft flaps 4, both arranged on the same plane. The outer shaft 2 has two pairs of openings corresponding to the two pairs of flaps on the inner shaft 1. The size of the openings is required to ensure that the rotation angle of the inner shaft 1 is greater than or equal to 90°.

[0024] When the box flipping roller conveyor needs to flip, the drive motor 6 drives the inner shaft 1 to rotate so that the inner shaft flap 3 on it and the outer shaft flap 4 on the outer shaft 2 are at a 90° position. Then the cylinder 8 pushes the sleeve 9 to move toward the outer shaft 2, so that the pin 10 in the sleeve 9 is simultaneously stuck in the slot of the outer shaft 2 and the cross slot of the inner shaft 1, so that the relative angle between the outer shaft 2 and the inner shaft 1 is fixed. At this time, after the box enters the box flipping roller conveyor, it is first transported to the flipping position by the conveying roller 7, and then the conveying roller 7 stops rotating. The drive motor 6 drives the inner shaft 1 and the outer shaft 2 to rotate 90° at the same time, so that the box is flipped and placed upright on the conveying roller 6. Finally, the conveying roller 6 rotates again to transport the flipped box to the downstream equipment, completing the entire work.

[0025] When the carton turning roller conveyor does not need to turn over, the cylinder 8 pulls up the sleeve 9 so that the inner shaft 1 and the outer shaft 2 are unlocked. Then the drive motor 6 drives the inner shaft 1 to rotate so that the inner shaft flap 3 on the inner shaft 1 and the outer shaft flap 4 on the outer shaft 2 are on the same plane. Then the cylinder 8 pushes the sleeve 9 so that the relative angles of the inner shaft 1 and the outer shaft 2 are locked. Then the drive motor 6 drives the inner shaft flap 3 and the outer shaft flap 4 to a horizontal position. At this time, after the packaging line enters the carton turning roller conveyor, it can be directly transported to the downstream by the conveying roller 7 without turning over, completing the switch from the turning state to the non-turning state.

[0026] The present invention has been described in detail with reference to preferred embodiments. However, variations and additions to the various embodiments will be apparent to those skilled in the art upon review of the foregoing description. It is the applicant's intention that all such variations and additions fall within the scope of the present invention.
