Flexible automatic feeding and blanking mechanism of manual pallet truck

Abstract

The invention discloses a flexible automatic feeding and blanking mechanism of a manual pallet truck, which is a full-automatic mechanical device used for feeding and blanking of the manual pallet truck. The flexible automatic feeding and blanking mechanism comprises a pillar which can move along a sliding rail, wherein a ball screw mechanism is arranged at the center of the pillar in the vertical direction, a suspension arm seat is connected with a movable nut in the ball screw mechanism, two sides of the suspension arm seat are symmetrically provided with suspension arms which stretch outwards, the suspension arms move in sliding fit with the pillar simultaneously when vertically moving along with the suspension arm seat, two connecting rods which can move in different directions along the stretching direction are arranged on each suspension arm, the arrangement direction of the two connecting rods is parallel to the movement direction of the sliding rail, and at least one end of each connecting rod is connected with a part taking manipulator which is a hanging claw or an electromagnetic suction arm. The flexible automatic feeding and blanking mechanism has the characteristic of flexibility, is compact in structure, and can be used for meeting needs of feeding and blanking of the manual pallet trucks of various specifications, so that the welding quality and production efficiency of the manual pallet trucks are effectively improved, the labor intensity of workers is alleviated, and a labor environment of the workers is improved.

Description

[0001] technical field [0002] The invention belongs to the field of mechanical manufacturing, in particular to a flexible automatic loading and unloading mechanism used in an automatic welding production line of a manual pallet truck. Background technique [0003] Manual pallet truck is a simple and effective logistics handling equipment, which is widely used in various sectors of the national economy such as workshops, warehouses, stations, ports, airports, etc. It is an efficient equipment for loading and unloading and short-distance transportation. With the rapid development of the economy and logistics industry, the supply of manual pallet trucks has been in short supply. my country is a big country in the manufacture and consumption of manual pallet trucks, but its production mode is labor-intensive, with low technical content and low added value.

Problems solved by technology

my country is a big country in the manufacture and consumption of manual pallet trucks, but its production mode is labor-intensive, with low technical content and low added value. With the deterioration of factors such as rising labor costs and RMB appreciation, my country's low-cost advantages will gradually lose. Therefore, How to speed up the technical transformation of manual pallet truck production and realize the automatic production of manual pallet truck is imminent

[0004] The manual pallet truck is welded by several special-shaped sheet metal parts. Due to the different application occasions, the manual pallet truck is divided into various specifications, and the sizes of each specification are not the same. At the same time, the welding process of the manual pallet truck mainly adopts robot master The production is organized by combining welding + manual repair welding. Operators need to manually transport the workpiece from the main welding station of the robot to the manual repair welding station to complete the repair welding work. The labor intensity is very huge.

[0005] It can be seen that the current loading and unloading process of manual pallet truck welding has the following limitations: 1) The working environment is poor and the labor intensity is high

Manual pallet trucks generally use CO 2 For gas shielded welding, workers inevitably inhale welding fumes and harmful gases during the process of moving workpieces, which seriously endangers the health of the group handling them; at the same time, workers need to continuously carry hundreds of manual pallet trucks every day, each manual The weight of the pallet truck is about 30kg, and the labor intensity of the workers is very huge

2) Labor intensive, difficult to recruit and manage

At present, the loading and unloading process of a manual pallet truck welding production line requires 3-4 operators to complete the processing. With the rise of labor costs in China, the appreciation of the renminbi, and the deterioration of environmental and resource bottlenecks, China's low-cost advantages will gradually disappear, and recruitment will occur. and management difficulties, it is difficult to complete order tasks on time
