DE19521020A1 - System for handling, transport, and storage of load carriers - Google Patents

Abstract

The carriers are lifted by a hoist and supplied to a high shelf and discharged from it onto a conveyor for dispatch. The load carriers are supported by a transport frame, on which they stay during the entire intermediate handling. They are supplied by a hoist to a high shelf for intermediate storage and despatched from it on demand On the frame the carriers are kept in a horizontal plane. There is a conveyor system with longitudinal, transverse, and transfer modules for directional changes. In the same plane are located frame storage units for incorporating into the conveyor circuit. The shelf is of a two-row type with an intermediate service passage.

Description

The invention relates to a system for handling, transport and Storage of typical load carriers such as containers, swap bodies or similar for container terminals and freight centers according to the generic term of the main claim.

The ever increasing quantities of goods have to be faster and more efficient handled, transported and stored. In addition to perfection and further automation of the existing handling technologies and Handling and transport equipment are new concepts, technologies and devices asked to increase the performance of handling, transport and storage of Containers in port terminals and goods distribution centers with high effectiveness and Help limit costs.

The possibilities of increasing performance in handling, transport and storage of containers with the existing technology and the previously used Systems and devices are largely exhausted. The automation of Sub-processes are more advanced. The number of devices used can be increase only to a limited extent and requires a great deal of expense, personnel and Surface. Half of the turnover time is dead time, due to the free travel of the Equipment. A significant increase is only possible through the use of new systems or Technologies attainable.

Newer systems include high-bay warehouses and continuously operating conveyor systems. These systems work with storage and retrieval machines and conveyors with universal Manipulation tasks such as B. for the realization of horizontal and vertical Movements that make it necessary, large dead loads of the devices used to move. Therefore, these devices are too energy-intensive operate. The motion sequences can only be divided and superimposed to a limited extent.  

The object of the invention is to avoid these disadvantages.

This task is carried out by a system for handling, transport and for the Storage of typified load carriers solved, in which a splitting of the Movements are carried out by using different modules. Thereby the individual movements can be superimposed and the energy requirements of the whole plant minimized.

This task is characterized by the characteristics of i. Claim resolved.

Appropriate designs of details are the subject of the subclaims. The following solution principles are implemented:

• - Use of load carriers together with support frames on roller conveyors are rollable and one or more containers or other containers of these Can take up and carry orders of magnitude,
• - Use of energy-saving roller conveyor assemblies with high throughput on the main conveyor routes,
• - Use of a high-bay warehouse with stationary vertical conveyors on each Shelf aisle,
• - Use of relatively light rack trolleys in every rack aisle and in each Shelf level,
• - Avoidance of any technically unnecessary lifting movements
• - Parallel work possibility of all assemblies and
• - Variable design of the system through the need-based assembly of devices and modules.

The invention is explained in more detail below using an exemplary embodiment explained. The accompanying drawings show

Fig. 1, a goods distribution system for the road-rail in a view Seitenan,

Fig. 2, the goods distribution of FIG. 1 in a somewhat different way in the plan view,

Fig. 3 is a support and transport frame for containers, in plan view,

Fig. 4 shows the supporting and conveying frame according to Fig. 3 in a side view;

Fig. 5 is a port terminal for the waterway system in a side view and

Fig. 6 shows a port terminal for the water-rail system in plan view.

The centerpiece of the goods distribution center of Fig. 1 is the high-bay warehouse 1. To the left of this, the containers 2 are transported in and out by truck 3 on the street and to the right on the tracks by freight cars 4 . A semi-portal crane 5 is arranged to be longitudinally movable as a loading and unloading device on the street side. A bridge crane 6 is provided in a hanging arrangement for loading and unloading on the rail side. It is telescopic so that the electrical train operation is not hindered. Its low design allows short lifting distances when lifting and lowering the load and allows a sufficient safety distance from the contact wire 7 of the railway.

Longitudinal conveyors 8 are arranged alongside the high-bay warehouse 1 in two rows on the street side and in three rows along the rail side. These longitudinal conveyors 8 are designed as roller conveyors with driven disc roller axes. As a result, the containers 2 placed thereon can be transported in the longitudinal direction.

According to Fig. 2 of the high-bay warehouse 1 is a respective cross-conveyor 9 is arranged on the two narrow sides of the feed. They are provided with two types of driven disc roller axles that allow movements of the containers 2 along the high-bay warehouse 1 and towards or away from this direction of movement.

Transfer devices 10 are provided between the longitudinal and transverse conveyors 8 and 9 for changing the direction. A closed continuous conveyor system is thus created from the longitudinal conveyor modules 8 , the cross conveyor modules 9 and the transfer devices 10 .

Since the containers 2 are used in standardized sizes and, due to their support structure, they are not capable of rolling in the ground, the carrying and transport frames 11 shown in FIGS . 3 and 4 are used. The containers 2 are placed on them and can thus be moved within the system.

These support and transport frames 11 are provided on storage units 12 . The carrying and transport frames 11 are ready there as a stack, the lower carrying and transport frames 11 always being removed or fed in and the stack above them being lifted out by known actuating elements. So that the carrying and transport frame 11 can be easily and with the shortest possible routes into the continuous conveyor system consisting of the various modules, the storage units 12 are arranged in the goods distribution center according to FIG. 2 at the corner points of the closed conveyor circuit.

On both storage sides of the high-bay warehouse 1 in the area of the aisles 16, the relevant cross conveyors 9 low-loader conveyors 13 are arranged. Through this, the container 2 located on the carrying and transport frame 11 is conveyed to the corresponding floor, transferred to racking trolleys 14 provided there in the service aisles 16 , conveyed to the compartment provided and transferred to it.

In Fig. 1, the container 2 in the high rack 1 are shown by broken lines. The arrows show possible routes of the containers 2 into or out of the shelves.

The high-bay warehouse 1 is designed in two rows, which means that the required container 2 can be removed at any time. No sorting is necessary.

The size of the high-bay warehouse 1 is dimensioned according to the required storage capacity. Depending on the throughput, either one side stores or the two opposite sides are provided for this, as in the exemplary embodiment.

According to FIGS. 5 and 6 the use of the modules of the continuous conveyor system is shown in connection with a high-bay warehouse 1 for a port terminal. FIG. 5 shows a water-road variant and FIG. 6 a water-rail variant.

A generally known container crane 16 with intermediate storage for the containers 2 is provided for loading and unloading the container ship 15 . The containers 2 are then transferred to automatically controlled industrial trucks 17 and deposited on the longitudinal conveyors 8 by them . In contrast to the previously described solution, the containers 2 are rotated at an angle of 90 during the transfer for transverse conveyance on the transfer device 10 and are thus conveyed in the direction of their longitudinal axis. The modules of the continuous conveyor running in the transverse conveying direction can then also be designed like the longitudinal conveyor 8 . The other devices and equipment belonging to the entire system, such as cranes, high-bay warehouses, road and track connections, are adapted to the specific conditions.
