Self-adaption gripper type discharge device and discharge method

Abstract

The invention relates to the technical field of ton bag discharge device structures, in particular to a self-adaption gripper type discharge device and a discharge method. The self-adaption gripper type discharge device comprises a rack, wherein the rack is provided with an overturning frame which is used for containing ton bags, and the overturning frame is of a frame structure which can be rotationally hinged to the rack and is provided with at least one opening. The self-adaption gripper type discharge device further comprises a fixing device which is used for fixing the ton bags, wherein the fixing device comprises a ton bag side wall fixing device and a ton bag bottom fixing device, the ton bag side fixing device comprises a plurality of pairs of opposite side suction cups which are arranged on the inner side of the overturning frame, and the ton bag bottom fixing device comprises a plurality of pairs of gripper devices which are arranged on the two sides of the bottom of the overturning frame and used for clamping the bottoms of the ton bags. The self-adaption gripper type discharge device is simple in structure, convenient to operate and capable of discharging materials in the ton bags completely and rapidly, the ton bags cannot be damaged, collection and recirculation of the ton bags are facilitated, the discharging difficulty is greatly lowered, and great popularization value is achieved.

Description

technical field [0001] The invention relates to the structural technical field of a large bag unloading device, in particular to an adaptive gripper type unloading device and a unloading method. Background technique [0002] At present, in the chemical industry, cement, grain, mineral products and other industries, most enterprises use manual or semi-automatic unloading methods when unloading large-scale bagged materials, that is, use a blade to directly cut through the bag to unload. The materials are either discharged by using a large bag with a small opening at the bottom, or by using an adsorption device at the bottom to absorb the large bag and turn it over for unloading. However, these unloading methods have high waste bag rate, high labor intensity, low discharge rate, and high residual material. And the inability to automatically adjust the state of grabbing the big bag according to the change of the material to ensure the stability of the unloading of the big bag, e...
