Description

Technical Field

[0002] Currently, the market offers pallet conveyor equipment that is compatible with various widths. However, when used with pallets of varying widths, this requires adjusting the guide distance. Currently, there are two methods for adjusting the guide distance: one is to adjust the front-to-back distance between the guide rods on either side, using guide plates on both sides coupled with photoelectric detection. This method requires manual adjustment, resulting in lengthy alignment and low efficiency. Alternatively, the guide plates on both sides are electrically controlled to automatically adjust the spacing. This adjustment method is costly and requires ongoing maintenance, making it inconvenient. Therefore, we propose a transport device compatible with multiple pallet sizes. Utility Model Content
