Technical Field

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

[0002] Pallets are commonly used devices for carrying goods. During transport, pallets are prone to shifting, which can cause misalignment between the pallet and the goods during stacking. Therefore, pallets need to be corrected during transport. Summary of the Invention

[0003] To address the problems existing in the prior art, this utility model provides a pallet straightening conveyor line that solves the problem of pallet offset during the conveying process.

[0004] To achieve the above objectives, the following technical solution is provided:

[0005] The pallet straightening conveyor line includes a pallet receiving roller conveyor, a three-track unit, a pre-straightening track, and a secondary straightening track. The three-track unit is connected to the pallet receiving roller conveyor and has three tracks. The output end of the three-track unit is connected to the pre-straightening track, which has a double-track structure. The output end of the pre-straightening track is connected to the secondary straightening track. A pair of first straightening plates are provided on both sides of the pre-straightening track, and a pair of second straightening plates are provided on both sides of the secondary straightening track. The distance between the second straightening plates is smaller than the distance between the first straightening plates.

[0006] The secondary correction track has a double track structure, and the width of the secondary correction track is greater than the width of the pre-correction track.

[0007] The front ends of the three track chains of the three track chain unit are inserted into the gap between the rollers of the receiving tray roller conveyor, and a lifting adjustment mechanism is provided at the lower part of the front end.

[0008] The lifting and adjusting mechanism includes a cam and a sliding support groove. The sliding support groove is installed at the lower part of the front end of the three track rails, and the cam is driven by a motor to drive the sprocket.

[0009] The receiving pallet roller conveyor is provided with a guide rod on its side. The front end of the guide rod is inclined, and the rear end is parallel to the conveying direction of the receiving pallet roller conveyor.

[0010] The end of the receiving tray roller is provided with a blocking block, which is located on the outside of the three-track unit.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] The pallet straightening conveyor line provided by this utility model obtains pallets through a pallet roller conveyor and initially positions the pallets. Then, it is lifted by the front end of a three-track unit to transfer the pallets onto the three-track unit. The pallets are then conveyed to a pre-straightening track to complete the pre-straightening of the pallets. Finally, the track is straightened by a secondary straightening track.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Example

[0022] like Figure 1-6As shown, this utility model provides a pallet straightening conveyor line, including a pallet receiving roller conveyor 10, a three-track unit 20, a pre-straightening track 30, and a secondary straightening track 40. The three-track unit 20 is connected to the pallet receiving roller conveyor 10 and has three tracks. The output end of the three-track unit 20 is connected to the pre-straightening track 30, which has a double-track structure. The output end of the pre-straightening track is connected to the secondary straightening track. A pair of first straightening plates 31 are provided on both sides of the pre-straightening track 30, and a pair of second straightening plates 41 are provided on both sides of the secondary straightening track 40. The distance between the second straightening plates 41 is smaller than the distance between the first straightening plates 31.

[0023] The receiving pallet roller conveyor 10 is a roller conveyor structure, while the three-track unit 20, the pre-correcting track 30, and the secondary correction track 40 are all track conveyor structures.

[0024] Multiple photoelectric sensors are installed along the three-track unit 20, the pre-correction track 30, and the secondary correction track 40 to determine when the pallet reaches the corresponding conveying position.

[0025] The front end of the first correction plate 31 is set as a narrowing guide structure, and the middle part is a parallel transition structure. The distance between the front ends of the two first correction plates 31 gradually decreases, and the pre-correction effect is maintained in the transition structure; the length of the transition structure is greater than half the side length of the tray.

[0026] The structural design of the second straightening plate is the same as that of the first straightening plate, except that the distance between the second straightening plates 41 is smaller than the distance between the first straightening plates 31. Thus, after the first straightening plate 31 corrects the tray, the second straightening plate corrects the tray again, thereby achieving more accurate position adjustment and output.

[0027] The secondary correction track 40 has a double track structure, and the width of the secondary correction track 40 is greater than the width of the pre-correction track 30.

[0028] The three track links of the three track links of the three track link unit 20 are inserted into the gaps between the rollers of the receiving tray roller conveyor 10, and a lifting adjustment mechanism 21 is provided at the lower part of the front end. Correspondingly, a flip shaft support structure is set at the rear end of the three track link unit 20, so that when the height of the front end of the three track link unit 20 is raised or lowered, it rotates slightly around the flip shaft at the rear end.

[0029] The lifting adjustment mechanism 21 includes a cam 22 and a sliding support groove 23. The sliding support groove 23 is installed at the lower part of the front end of the three track rails. The cam 22 is driven by a motor to drive the sprocket. The cam 22 is supported in the sliding support groove 23, so that a sliding support is formed between the cam and the sliding support groove 23 during the driving process, thereby controlling the height of the front end of the three track rails.

[0030] The receiving pallet roller conveyor 10 has a guide rod on its side. The front end of the guide rod is inclined, and the rear end is parallel to the conveying direction of the receiving pallet roller conveyor 10.

[0031] The end of the receiving tray roller 10 is provided with a blocking block, which is located on the outside of the three-track unit 20.

[0032] Compared with the prior art, the advantages of this utility model are as follows:

[0033] The pallet straightening conveyor line provided by this utility model obtains a pallet through the pallet roller conveyor 10 and initially positions the pallet. Then, it is lifted by the front end of the three-track unit 20 to transfer the pallet onto the three-track unit 20. The pallet is then conveyed to the pre-straightening track 30 to complete the pre-straightening of the pallet. Finally, the track is straightened by the secondary straightening track 40.

[0034] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
