Vertical conveyor system for piece goods

The invention relates to a conveying device for parts, in particular returned goods, with several conveyor platforms arranged one above the other which convey the parts upwards and/or downwards; and with several floors fixed in a vertical direction as loading and unloading stations, which are arranged parallel to the conveyor platforms one above the other and whose distances from one another correspond to the distances of the conveyor system.

&bull; Vertical conveying devices, in particular floor conveyors such as circulating lifts for general cargo, are known, whose conveyor platforms serve loading and unloading stations in a circulating manner. These devices are complex and space-consuming due to their double row of conveyor platforms arranged next to each other. In addition, vertical conveying devices for general cargo &bull;are known, which use a platform as a floor conveyor to connect a lower and upper loading platform.

These devices usually have the task of connecting two continuous conveyors at different levels.

The object of the invention is to improve a conveying device of the type mentioned at the outset so that the parts to be transported can be stored within the conveying device.

This object is achieved according to the invention in that transport devices are attached approximately at the height of the floors, by means of which the parts can be transported from the conveyor platform molds to the floors and in the opposite direction from the αε-ηι floors to the conveyor platform.

Such a conveyor device allows the parts to be temporarily stored before they are transported further. Temporary storage is extremely beneficial for a wide variety of work processes and transport tasks.

In addition, when the parts are fed in from one end, the conveyor can not only transport the parts to the second end, but can also transport the parts back to the input end after intermediate storage, so that the conveyor can be used purely as a storage facility. The storage capacity can be increased as required, so that not only a high level of flexibility, but also a high level of adaptability can be achieved. Furthermore, the conveyor has a high level of functional reliability with a simple design and small external dimensions.

Particularly safe operation with a simple design is achieved when the transport devices are formed by slides. For this purpose, it is also proposed that at least one of the transport devices moving the parts down from the floors is a driven roller conveyor.

It is particularly advantageous if the lowest and/or

* i 4 · f III * · **·# * i It &diams; * Il ti < I f &igr;&igr; f &igr; ft ti% »

h the topmost floor or several floors is (are) formed by a horizontal transport device, in particular a conveyor belt. Alternatively, it is proposed that a horizontal transport device, in particular a conveyor belt, is connected to the bottom and/or topmost floor.4

The storage capacity of the conveyor device can be easily increased by arranging storage areas at the same height next to the fixed floors.

A particularly advantageous design of the conveyor device is obtained if the distance between two floors corresponds to the height over which all conveyor platforms can be moved up and down alternately as a group.

--. In this case, the parts transported by the conveyor platforms from one floor to the next floor can be moved by the transport devices from the conveyor platform to the next floor mentioned and remain there at least until the adjacent conveyor platform has reached this floor, in order to then be moved by the transport device to the conveyor platform located at the same height.

An embodiment of the invention is shown in the drawing in a vertical view and is described in more detail below.

In a frame 1, several horizontal conveyor platforms 2 are arranged one above the other at constant distances and are attached to one or more vertical conveyors, which move all platforms 2 together by the distance, and thus the vertical distance A, alternately ^up and down. All five platforms 2 shown in the drawing are thus moved up and down simultaneously by the distance A in cycles.

At the level of the platforms 2 there are four floors as loading and unloading surfaces which are arranged vertically one above the other at a distance A. Below the lowest floor 3 there is a loading conveyor k at a distance A and above the top floor there is a unloading conveyor S. The loading conveyor U can also be formed by a unloading conveyor and the unloading conveyor 5 by a loading conveyor. These conveyors can be conveyor belts or roller conveyors.

The floors 3 arranged next to the platforms 2 thus form storage areas on which the parts to be transported, in particular piece goods, are pushed from the floors. The size of the floors 3, in particular their width, can correspond to that of the platforms 2 and can be extended as desired. In particular, additional floors can be arranged next to the floors 3 at the same height on one of the three remaining sides or several of these sides in order to create even more intermediate storage space there.

The cyclical up and down movement of all platforms 2 together always only takes place by the height A, so that, for example, the lowest platform 2 is only raised by the feed conveyor U by the amount A, whereby all other platforms are also raised and then the lowest platform is moved back down by the height A. All conveyor platforms in the group are thus moved up and down alternately by the distance Ä, so that little construction effort is required.

In order to move the parts, in particular the piece goods T from the platforms 2 to the floors 3 or the conveyors 4, 5 and in the opposite direction, numerous transport devices 6 are attached to the frame 1, which move the parts horizontally using sliders. These sliders

can be driven hydraulically, electromechanically or pneumatically by cylinder-piston units. Alternatively or additionally, the platforms 2 and/or the floors 3 can also have driven roller conveyors.

The conveyor works as follows:

Piece goods T, such as boxes, are transported by the feed conveyor k and pushed by the lowest slide 6a from the conveyor U onto the lowest platform 2a. After that, all platforms 2a to 2e move upwards together, so that platform 2a is now level with the floor 3a. There, the piece goods are pushed onto the floor 3a by the slide 6b, and then all platforms move downwards again! The part that has meanwhile been transported by the feed conveyor H is now pushed onto the platform 2a by the slide 6a, and at the same time the part on the floor 3a is pushed onto the platform 2b by the slide 6c. After that, all platforms move upwards again, and the part or parts are pushed off the platform 2a. Piece goods are pushed onto the floor 3a ₃ and the part on the platform 2b onto the floor 3bI . Now all platforms are moved downwards again and the part which has meanwhile arrived on the feed conveyor U is pushed together with the other parts onto the floors 2a to 2c. The process continues in this way in cycles so that all floors are gradually occupied and then the top part is supplied to the discharge conveyor 5.

In an alternative, instead of the discharge conveyor, another floor 3 can be arranged and the conveyor can be emptied by moving backwards after all floors have been filled, i.e. the platforms 2a to 2e are used to empty the conveyor in cycles by making the conveyor 4 the discharge conveyor. In another alternative

A discharge conveyor may be provided at the level of the feed conveyor H on the other side of the platform 2a, which ensures removal.
