Lifting device

Two-tier roller systems are used to return containers to assembly lines.

The lower level is used to feed the containers onto the conveyor belt, the upper level is used to transport the empty containers away.

For this purpose, the part of the lower level on which the empty containers are located is raised using hydraulic, pneumatic or electrical devices.

These devices must be tilted due to the necessary ergonomic accessibility of the parts to be assembled in the containers.

This is done by hydraulic or pneumatic elements, which are very expensive and also require enormous control effort. Furthermore, the matter is

The inventor has made it his mission to eliminate these disadvantages. He suggests that the desired ergonomically necessary tilting can be achieved using the slide guide.

Fig. 1 shows a two-level lifting device (1) in perspective. There are two roller levels (3a + 3b) on a frame (2). A carriage (6) with a platform (6a) equipped with rollers hangs on a chain (5) on a lifting device (A) (e.g. an electric hoist). The container (6) with, for example, parts to be assembled stands on this.

This carriage is guided on the right and left at 2 points (e.g. 2 rollers)7 + 8 in a guide (9). The shape of the guide determines the optimal inclination of the platform (6a) and thus of the container (6b) for grip readiness, i.e. the ergonomically best inclination for handling.

In the example presented, the guide (9) is tilted forward for the upper roller (8). The roller (8) follows this inclination and the platform (6a) also tilts, since the

The angle between the strut (10) on which the two rollers (points 7 and 8) are located and the platform does not change. (both are rigidly connected to one another) The segment (11) of the guide (9) and any other segment can be designed to be interchangeable in order to be able to adapt the inclination behavior to the intended use. The guide (9) can also be designed so that the lower roller moves backwards and upwards in order to tilt the platform. It is also possible to guide the upper point, the upper roller forwards and upwards, and the lower roller backwards and upwards, in order to prevent one roller from swinging too far away from the middle of the guide. When the container is empty, the carriage (6) is pulled upwards so that the roller track of the carriage and that of the plane (3b) coincide.
The empty container rolls from the carriage onto the level (3b).
