Description

Technical Field

[0001] The utility model relates to the field of conveyor loading and unloading operations, in particular to a material conveying deviation correcting device. Background Art

[0002] When conveying materials, the conveyor assembly can be set on the horizontal swinging arm to achieve the conveying end covering the preset external transfer position. This results in the material posture being offset relative to the conveying direction of the swinging conveying assembly after the front conveying assembly conveys the material to the swinging conveying assembly. The offset needs to be corrected to ensure the consistency of the material output posture.

[0003] The existing method of posture correction is to set a transverse baffle on the conveyor belt, and the conveyor belt transports the material to the baffle so that the material fits the baffle, thereby correcting the posture of the material. The above method is suitable for continuous transportation of single-row materials. In the transportation of double-row materials, the material is transported from the front conveying component to the swinging conveying component at the rear end. Since the conveying component at the rear end swings, when the double-row materials reach the conveying component at the rear end, the posture of a pair of materials not only shifts in the conveying direction, but also staggers front and back. In this case, if only the baffle at the front end is used to correct the posture, the material at the front end will contact the baffle first, and interfere with the material at the rear end, thereby affecting the posture correction of the material. Utility Model Content

[0004] In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a material conveying deviation correction device, which can adapt to the posture correction of double-row materials, especially double-row box materials conveying.
