Description

TECHNICAL FIELD

[0001] The present application relates to the field of stacker trucks, in particular, to an unmanned stacker truck capable of protecting goods. BACKGROUND

[0002] The unmanned stacker truck is not much different from the traditional manually driven stacker truck in essential characteristics, and is mainly used for flat transportation and stacking. The manually driven stacker truck in the form of stacking completely judges the position of the fork by the visual sense of the driver when stacking goods or taking goods from a high place, while the unmanned stacker truck must rely on various sensors to judge when stacking. The main parts associated with the unmanned stacker truck when taking and placing goods are the fork assembled on the stacker truck itself, the pallet carrying goods, and the shelves arranged in the warehouse, etc.

[0003] However, the existing unmanned stacker truck cannot judge whether the goods are stable and whether there is a risk of falling by visual sense, and when the goods fall, it will cause great danger to the pedestrians, so a guardrail structure is usually installed on the shelf of the stacker truck to shield the goods and avoid falling, but the guardrail will block the fork of the stacker truck, so the position of the guardrail on the shelf is usually adjustable.

[0004] The guardrail structure usually installed is usually fixed, when the forked goods are too large, the guardrail cannot be adapted to the goods, and the guardrail needs to be disassembled and reassembled to adapt to the size of the goods, when the goods are too small, there is a gap between the guardrail and the goods, so that the goods are easy to shake during transportation, and there is a risk of falling, so an adjustable guardrail is needed to make the guardrail close to the goods to avoid shaking, but when there are multiple goods and the sizes of the goods are inconsistent, the guardrail can only contact the large goods, and the small goods are still at risk of falling.

[0005] Therefore, an unmanned stacker truck capable of protecting goods is needed. SUMMARY
