Parallel moving frame and its unloading device based on double power drive

Abstract

The invention discloses a parallel moving frame driven by double power and its unloading device. The parallel moving frame includes: an upper cross bar, which is fixed with an upper slider and an upper power driving device, and the upper power driving device can control the upper slider to only Move back and forth along the upper crossbar; the lower crossbar is set parallel to the upper crossbar, the lower crossbar is fixed with the lower slider and the lower power drive device, and the lower power drive device can control the lower slider to only go back and forth along the lower crossbar Move; the top of the vertical rod is connected with the upper slider through the upper adjustment device, and the bottom is connected with the lower slider through the lower adjustment device; when the upper slider and the lower slider drive the vertical rod to move in the same direction, the upper adjustment device Or the lower adjustment device can make the vertical bar rotate an angle relative to the upper cross bar or the lower cross bar, and the upper adjustment device and / or the lower adjustment device can make the vertical bar move up and down a certain distance relative to the upper cross bar or the lower cross bar. The invention has the beneficial effects of long service life, suitable for unloading on shelves of different heights, and high 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 th...

[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.
