Parallel moving frame based on dual-power driving and unloading device thereof

Abstract

The invention discloses a parallel moving frame based on dual-power driving and an unloading device thereof. The parallel moving frame based on dual-power driving comprises an upper cross rod, a lower cross rod and a vertical rod, wherein an upper sliding block and an upper power driving device are fixed to the upper cross rod, and the upper power driving device can control the upper sliding block to move back and forth only along the upper cross rod; the lower cross rod is parallel to the upper cross rod, a lower sliding block and a lower power driving device are fixed to the lower cross rod, and the lower power driving device can control the lower sliding block to move back and forth only along the lower cross rod; the top of the vertical rod is connected with the upper sliding block through an upper adjusting device, and the bottom is connected with the lower sliding block through a lower adjusting device; when the upper sliding block and the lower sliding block drive the vertical rod to move in the same direction, the upper adjusting device or the lower adjusting device can enable the vertical rod to rotate by an angle relative to the upper cross rod or the lower cross rod, and the upper adjusting device and / or the lower adjusting device can enable the vertical rod to vertically move by a certain distance relative to the upper cross rod or the lower cross rod. The parallel moving frame based on dual-power driving has the beneficial effects of being long in service life, suitable for unloading goods shelves with different heights and high in unloading efficiency.

Description

technical field [0001] The invention relates to a parallel moving frame driven by double power and an unloading device thereof. Background technique [0002] Moving objects through the guide rail and slider structure is a common structure in the machinery industry. In order to improve stability, a double guide rail structure is usually selected. To control the two sliders to move back and forth along the two guide rails, there must be a power drive device. When double guide rails When the spacing is large, you can usually choose a mechanical synchronous structure to make the slider move synchronously. In one application, when the goods are unloaded on shelves of different heights through the guide rail and slider structure, the height of the shelf may be very high. At this time , the cost of choosing a mechanical synchronous structure is very high and heavy. It will be more advantageous to use dual power to drive the movement of the slider separately, but the structure of ...

[0002] Moving objects through the guide rail and slider structure is a common structure in the machinery industry. In order to improve stability, a double guide rail structure is usually selected. To control the two sliders to move back and forth along the two guide rails, there must be a power drive device. When double guide rails When the spacing is large, you can usually choose a mechanical synchronous structure to make the slider move synchronously. In one application, when the goods are unloaded on shelves of different heights through the guide rail and slider structure, the height of the shelf may be very high. At this time , the cost of choosing a mechanical synchronous structure is very high and heavy. It will be more advantageous to use dual power to drive the movement of the slider separately, but the structure of the dual power drive must maintain very good synchronization. However, the high-precision motor drives the synchronous wheel When the synchronous belt drives the slider to move, there will be some errors. The existence of this error will cause torsion between the two sliders and the connecting rod. Unreasonable design will damage the slider or related structures connected with the slider, such as the connecting rod.
