automatic charger .

Description:

The loading machine is a conveyor system for picking up, conveying, positioning and setting down objects.

Various conveyor systems (mostly wheelchair lifts) are already known that enable lifting and pushing movements.

The innovation is that this charging machine

1.) all necessary movements from one end position to the other are carried out completely automatically on command, without the need to intervene in the movement sequence,

2.) is suitable for installation in vehicles with a flat loading area (e.g. cars with a tailgate or vehicles with a side sliding door),

3.) as a compact device it enables easy and quick installation and removal,

4.) is not only suitable for wheelchairs.

Objects or devices can be transported with this loading machine. Objects can be, for example, general everyday objects such as boxes, packages, containers, etc. Devices can be, for example, machines, transport devices or other self-operating devices. The loading machine can either be operated stationary or, for example, installed in vehicles. It can also preferably be used only for loading vehicles, e.g. for mobile equipment in handicapped transport (wheelchairs or other vehicles, etc.).

Claims (1)

..# ·· ·· ··· «»j· Sixth Protection claims: Automatic loading device, characterized in that the material to be conveyed, which is fixed on a receiving table, is subjected to rotation or tilting during or in addition to linear conveying. Subclaim 1: All movements during conveyance between the end positions are coordinated and take place automatically after the start command. Subclaim 2 : The loading machine consists of a receiving table 1 onto which the material to be conveyed 2 is placed. This receiving table 1 is articulated on a longitudinally guided carriage 3 in D, where it is lifted or tilted during the conveying process, for example from a vertical position (Fig. 1) at level X by means of a special rotary tilting device into a horizontal position (Fig. 2) at level Z. The carriage 3 is in turn moved in a housing 4 by means of a gear 6 from one end position A (as per Fig. 1) to the other end position B (as per Fig. 2). Subclaim 3 : The loading machine can be operated by means of compressed air, hydraulics or an electric motor (220 V or 12/24 V direct current) 5 via a gear 6 and a feed device 8. Subclaim 4: Several motors 5 and gears 6 can act on the feed device 8. Fig. Subclaim 5: The transmission 6 can be, for example, a gear or toothed belt transmission. Subclaim 6: The carriage 3 can be guided in the housing 4, e.g. by means of roller or linear bearings 9 on guide rails 12 (or in guide profiles). Subclaim 7: The table 1, which is rotatable on the carriage 3, can either be driven by a rope, chain or belt or can be brought into its respective end position according to A or B by means of a rotary tilting device. Subclaim 8: The rotary tilting device consists of the crank 15 mounted in the joint E on the slide 3 and the push rod 7 mounted on it in the joint F, which is hinged to the receiving table 1 at G. An actuating lever 10, also mounted in E, is firmly connected to the crank 15. This is guided by a guide roller 11 in a control rail 16. The rotary tilting movement preferably takes place in an end position of the slide 3, e.g. A. (Fig. 1) Subclaim 9: The push rod 7 can also be connected with its joint H directly to the nut for spindle drive 17 or to the cardan shaft 18. The joint H is then additionally guided in a guide rail 22. During conveyance to A, the joint G is then held to the carriage 3 until it approaches the end position A and the rotation-tilting process is initiated. Conversely, during conveyance from end position A to end position B, the carriage 3 is initially held to the housing 4 until the rotation-tilting movement around joint D ends. This holding is controlled, for example, by the nut for spindle drive 17 (Fig. 3). Subclaim 10: The carriage 3 can consist of several carriages arranged telescopically one inside the other. Subclaim 11: The feed device 8 for the carriage 3 in the housing 4 can be a cable, chain, belt or spindle drive. Shown in Fig. 1, 2, 3, 4 is a spindle 8 driven by a motor and gear 6, which moves the slide 3 by means of a nut 17 connected to it. Subclaim 12 A fastening device 13 adapted to the conveyed material can be attached to the table 1, with which the conveyed material 2 can be held on the receiving table 1, for example by a clamping movement using elastic clamps 27. At the same time, this can be secured by receiving brackets 14 (Fig. 6). Subclaim 13: When transporting a device that can be moved on the road (e.g. wheelchair, sack barrow, transport trolley, etc.) into a vehicle (e.g. car, trunk, etc.), the table 1 is initially approximately vertical (Fig. 1) and slightly above the road, so that the conveyed goods 2 can be easily pushed towards it and secured (e.g. clamped) using a fastening device 13. During the conveying process, the conveyed goods 2 are first raised to the height of the loading platform (e.g. trunk) by a rotary tilting movement and then brought to the end position B (Fig. 2) by the slide 3. (When unloading, the process is exactly the opposite). Subclaim 14: If the axes of the joints D, E, F, G are all arranged parallel and horizontally, this results in a tilting lifting and feeding device in which the load is conveyed between end position A at level X and end position B at level Z (e.g. wheelchair loading machine) (Fig. 1) Subclaim 15: If the axes of the joints D, E, F, G are all arranged parallel and vertically, this results in a turning and feeding device in which the end positions A and B are at the same level Z. Subclaim 16: The nut for spindle drive 17 can be connected to the slide 3 by means of a cardan joint 18. The joints 19 can consist of cylindrical screw heads, for example. The intermediate space 20 (spindle nut 17/cardan joint 18) and the intermediate space 21 (cardan joint 18/slide 3) can consist of vibration-damping material.
(Fig. 5) Subclaim 17 The advantages of subclaims 14 and 15 can be combined into one device by means of two devices. Subclaim 18: With a device according to dependent claim 17, one can, for example, convey from end position A (either from level X or at level Z) to end position B at level Z, whereby turning or tilting is possible. Subclaim 19: For safety reasons, the loading machine can only be in motion as long as the command device is activated (dead man switch). Subclaim 20: When entering the end position B, the goods to be conveyed (wheelchair) can be moved against the catch arms 26 and thus secured for subsequent transport. Subclaim 21: The receiving table 1 can be provided with stabilizing supports and the housing 4 with guide rails 24 so that unwanted vibrations and movements of the conveyed material are avoided during conveying. The guide rails 24 can also be connected directly to the work base P. Subclaim 22: In the case of 12/24 volt direct current, the power supply can be via the cigarette lighter in the vehicle. Subclaim 23: The housing 4 of the automatic loading device can be attached to the work base P using variable fastening parts, fixed screws or magnetic holders 25.
