Description

Technical Field

[0001] This utility model relates to the field of pallet conveying technology, and in particular to a pallet rotation and straightening conveying system. Background Technology

[0002] In the production process of barrel-filled products, after filling is completed, the barrels need to be strapped to pallets to facilitate the loading and stacking of the barrel-filled products. This involves two conveyor lines: the barrel-filling production line and the pallet feeding line. Since the barrel-filling production line is usually linear, the pallets must be fed to the barrel-filling production line perpendicular to it.

[0003] However, space in production workshops is limited, so most manufacturers cannot afford to have the pallet feeder line perpendicular to the production line for filling barrels. Therefore, almost all manufacturers design their pallet feeder lines as corner structures, meaning the line runs parallel to the barrel filling production line, and then supplies the pallets to the barrel filling production line via the corner structure.

[0004] The current corner structure design, directly supplying the packaging drums to the filling production line, means that the drums cannot be straightened after rotation and are directly fed into the filling line. Furthermore, because the pallet straightening system is relatively long, adding another pallet straightening system after the corner structure would create a large L-shaped structure, further increasing the space occupied by the entire pallet delivery line. Therefore, the challenge lies in ensuring that the pallet can be directly supplied to the packaging drum filling production line after rotation, thereby reducing the floor space required. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model provides a pallet rotation and correction conveying system, which solves the problem that the pallet cannot be directly and accurately aligned with the direction after being rotated in the conveying direction.

[0006] To achieve the above objectives, the following technical solution is provided: The pallet rotary straightening conveyor system includes a pre-straightening combined roller chain mechanism, a first shrinking straightening track, a second shrinking straightening track, a transition connecting track, a track rotation platform, and an output track. The pre-straightening combined roller chain mechanism comprises a segmented roller conveyor section and a three-track section. The segmented roller conveyor section is inserted into the input end of the three-track section, and the three-track section can rise and fall to transfer pallets vertically conveyed by the segmented roller conveyor section onto the three-track section. The first shrinking straightening track is a parallel double-track structure, and the double tracks of the first shrinking straightening track are connected to the pre-straightening track. The connection positions of the three track sections of the positive roller chain mechanism adopt a cross-staggered structural layout; the second shrinkage straightening track is a parallel double track structure, and the width of the double track structure of the second shrinkage straightening track is greater than that of the double track structure of the first shrinkage straightening track. At the connection position, the first shrinkage straightening track is inserted into the second shrinkage straightening track; the output end of the second shrinkage straightening track is connected to the transition connecting track; the output end of the transition connecting track and the input end of the output track are both three track structures that are inwardly V-shaped, so as to connect with the three track structure of the track rotation platform.

[0007] The spacing between the three tracks of the track rotating platform is smaller than the spacing between the three tracks of the transition connecting track and the output track. Furthermore, both ends of the three track structure of the track rotating platform are arranged in a protruding pointed shape, and the edges are located on the circumference centered on the rotation center of the track rotating platform.

[0008] When the track rotating platform docks with the transition connecting track, the isosceles triangle formed by the three track ends of the track rotating platform is located inside the isosceles triangle formed by the three track ends of the transition connecting track, and the axes of the two isosceles triangles overlap; while the three track ends of the transition connecting track are all located outside the circumference centered on the rotation center of the track rotating platform, so as to avoid interference between the track rotating platform and the transition connecting track during rotation.

[0009] When the track rotating platform is connected to the output track, the isosceles triangle formed by the three track ends of the track rotating platform is located inside the isosceles triangle formed by the three track ends of the output track, and the axes of the two isosceles triangles overlap; while the three track ends of the output track are all located outside the circumference centered on the rotation center of the track rotating platform, so as to avoid interference between the track rotating platform and the output track during the rotation process. Photoelectric sensors are installed on both sides of the three track ends of the track rotating platform to obtain signals of the tray being in place and leaving.

[0010] The tracked rotating platform rotates 90 degrees each time.

[0011] The first shrinkage correction track, the second shrinkage correction track, the transition track, and the output track are each driven by an independent motor and reducer.

[0012] The segmented roller conveyor section and the three-track section of the pre-correction combined roller chain mechanism are driven by independent motors and reducers, and the lifting of the three-track section is driven by an independent motor.

[0013] The tracked rotating platform is driven by an independent motor through a three-track transmission, and its rotation is driven by an independent motor.

[0014] Compared with the prior art, the advantages of this utility model are as follows: The pallet rotation straightening conveyor system provided by this utility model pre-straightens the pallet through a pre-straightening combined roller chain mechanism. Then, before the chain track rotating platform, the straightening action of the chain track is performed twice to ensure that the pallet is accurately centered. Thus, when the chain track rotating platform performs a 90-degree rotation operation on the pallet, the pallet's orientation can be ensured to be accurate when it is supplied to the production line.

[0020] When the track rotation platform 50 is connected to the output track 60, the isosceles triangle formed by the three track ends of the track rotation platform 50 is located inside the isosceles triangle formed by the three track ends of the output track 60, and the axes of the two isosceles triangles overlap; while the three track ends of the output track 60 are all located outside the circumference centered on the rotation center of the track rotation platform 50, so as to avoid interference between the track rotation platform 50 and the output track 60 during rotation.

[0021] Photoelectric sensors are installed on both sides of the three-track end of the track rotating platform 50 to obtain signals of the tray being in place and leaving.

[0022] The tracked rotating platform 50 rotates 90 degrees each time.
