Background technology
Conveying machinery is with continuous, uniform, stable mode of movement, machinery along certain circuit carrying or conveying bulk material and work piece, due to conveying machinery have can in an interval continuous transport material, operating cost is low, efficiency is high, the feature such as it is easily controlled, thus it is widely used in commercial production, it is one of basic equipment realizing material conveying carrying in commercial production, therefore, in modern production firm, various automatic assembly lines broadly fall into the conveying machinery of automatization.
Along with the industrialized fast development of China, industrial efficiency increases substantially, and conveying machinery status in the industrial production is also stepping up. It is known that a lot of heavy mails or small-sized Assembly part are required for adopting hopper to contain now, and part processing enterprise there is also certain requirement for its stack manner in the assembling process carry out this kind of part. Such as small-sized Assembly part, processing enterprise is in order to ensure the seriality of its assembling, it is desirable to it is maintained at three layers in the stacks as high of hopper. So, the carrying how realizing this type of hopper just becomes the difficult problem affecting processing enterprise. In current most of processing enterprise, corresponding processing mode remains as artificial stacking carrying, so not only occupies a large amount of labour force, and whole stacking process is very arduous, and sometimes also can cause the damage of article, and handling efficiency is low.
And part adopts the problem that the enterprise of the stacking carrying operation of mechanization is faced with other. Wherein main problem is that the mechanical lifting conveyer device extensively used at present adopts the mode that cylinder or motor directly act on hopper to complete Skip hoisting when its lifting operation mostly the most. Although this kind of mode of operation can complete corresponding operation, but it is bigger for the consuming of production capacity, because hopper in order to ensure the effect of Skip hoisting, can be carried arranging both sides cylinder, also can be added detection sensor in the course of processing by most of processing enterprises simultaneously. So, not only make whole control system sufficiently complex, greatly reduce the reliability of device, also result in the significant wastage of production capacity simultaneously.
CN203998218U relates to a kind of hopper class vertical conveyor, including bearing, base plate, cylinder, rolling bearing units, two column fences, motor, ball-screw, nut, lifting platform and two guide posts, described bearing is respectively symmetrically and is arranged on the left and right sides, base plate bottom, square groove is offered on front side of base plate, the left and right sides of square groove is provided with boss, cylinder two ends are fixed on boss respectively through rolling bearing units, two column fences are separately fixed at boss both sides, motor is positioned at floor rear, ball-screw is connected by shaft coupling with electric machine main shaft, nut is arranged on ball-screw, it is connected with nut on rear side of lifting platform, two guide posts are each passed through the left and right sides of lifting platform.
Although this utility model solves the problem of hopper vertical transport, but it substantially remains employing driving device and directly drives the mode of hopper to complete operation, not only less stable, and cannot complete the sequence of operations such as the crawl to hopper, placement.
