Description

A spreader and a material conveying system

technical field

The present application relates to the field of material conveying, and in particular to a spreader and a material conveying system including the spreader.

Background technique

With the development of modern logistics and warehousing, there are more and more applications of intelligent conveying equipment in warehousing and manufacturing production lines, such as line-side automatic power tools, automatic assembly manipulators, automatic navigation cars in automobile assembly lines, and according to Liftable spreaders of different models and different positions, etc. In the conveying track of the automobile production conveying system, there are sometimes ups and downs, which will affect the stability of the conveying, and even the production beat; on the assembly line, some stations require the material table to reach the required height before it is easy to assemble. The spreader has no lifting function, so it needs to be completed with the help of an external lift. As an independent working unit, the liftable spreader that operates independently is not affected by the operation rhythm of the whole line, and has flexible production and high flexibility. More and more applications.

In order to improve the automation of the entire assembly line, it is necessary for the swing arm or manipulator that the spreader contacts with the workpiece to have the function of automatic opening and closing. However, in actual work, the spreader needs manual participation in the operation of grabbing and putting down the workpiece. , the efficiency is relatively low, how to realize the automatic opening and closing of the swing arm of the spreader at low cost is the first problem we have to solve.

In addition, on the assembly line, some stations have higher requirements on the positioning accuracy and stability of the spreader. For example, in the automobile assembly line, when the automobile body is hoisted from the interior line to the chassis line, the hoist must have good stability. There should be no excessive shaking during the hoisting process. The height of the material to be hoisted can be precisely controlled, and no tilting can occur during the lifting and lowering of the material. Due to the problems of noise and control accuracy, the hydraulic lifting mechanism is rarely used in the above occasions, but the lifting mechanism such as accumulation chain and belt under the control of the motor is mostly used. Some spreaders lack a lateral stabilizing mechanism. In the process of lifting and dropping the spreader, manual participation is required, which is not only inefficient, but also not conducive to intelligent control. In order to improve the stability of the spreader, a scissor mechanism is used in some occasions , the patent application number is CN201120213245 provides a new single-section anti-rotation spreader. The anti-rotation spreader uses two pairs of gears to mesh, and connects the upper and lower sets of gears through connecting rods. On the hoist, when the chain hoist is raised and lowered, the equalizing beam expands and shrinks at the same time, and the gears rotate together, so as to prevent the hoist from rotating and tilting and keep the car body stable. It solves the problem that the multi-section scissor fork anti-rotation mechanism cannot guarantee the rotation of the long-stroke spreader, meets the assembly requirements of large-scale automobile production lines, and plays the role of mechanical protection in the event of chain breakage. But this patent still has some deficiencies: 1. The structure of the connecting rod is used to replace the scissor mechanism of the multi-link. When the horizontal dimension of the connecting rod reaches the maximum, the lifting stroke of the spreader with high requirements for space layout will be affected; 2. There is no synchronization device for the two chain hoists, which can easily cause asynchrony during operation, and this This kind of asynchrony makes the force of the equalizing beam uneven, and this uneven force needs to be borne by the connecting rod and gear, which requires very high strength for the connecting rod and gear.
