Abstract

From the discharge point the load is transferred to a remote controlled lift truck with three pairs of forks by a grab system, the truck conveying the load into a jacked-up lorry. Pref. the position of the lorry is determined by guide rods, pressed against the lorry on either side. Parallel to the guide rods are mounted light sources, emitting light beams impinging on photosensitive layers which provide position indication of the lorry to a computer. The computer aligns a lift truck supporting platform with the centre of the lorry along its longitudinal axis. The light sources may be partly covered by a semi-transparent mirror, providing impingement on two independent photosensitive layers. The grab system has swing members for retention and safe transport of pellets, after mutual interconnection. The lift truck is guided by a light beam.

Description

Ileschreihung: LKW-Beladegerät für heckseitige 1§ladungIleschreihung: truck loading device for rear loading

Dieses LKW-Beladegerät hat die Aufgabe, Paletten automatisch von einer mehrstöckigen Palettenanlage in einen LKW von der Heckseite her zu verladen.This truck loader has the task of automatically loading pallets from a multi-storey pallet system to be loaded into a truck from the rear.

Bisherige Recherchen zeigten, daß es im EG-Bereich, Japan und USA, keine diese Aufgaben erfüllende Maschine gibt.Previous research has shown that in the EC, Japan and the USA, there is no machine capable of performing these tasks.

Der Beladevorgang: Der Greifer (7) fährt in Position I, um eine Palette (3) aufzunehmen, klappt seine Schwingen (7b) aus, die sich durch Bolzen (7c) verbinden und hebt die Palette an und befördert sie zu Position II. Während dies geschieht, wird die Position des LI(W (2) automatisch festgelegt. Zuerst wird er durch eine Hubvorrichtung (8) aufgebockt und verankert, daß er sich auch bei Gewichtsverlagerung nicht bewegt. Es werden Fiihrungsstangen (9) ausgeklappt, an denen Lichtquellen (10), nachfolgend Laser genannt, angebracht sind. An beiden Seiten des LKW's schicken die Laser ihr Licht auf einen halbdurchlässigen Spiegel (all), der einen Teil gradlinig weiterleitet, den anderen entsprechend ablenkt, sodaß zwei lichtempfindliche Schichten (12) getroffen werden, die einem Rechner die genaue Position des LKW mitteilen. Dieser Rechner speichert die Werte. Der Greifer hat inzwischen vor den dreigabelpaarigen Hubwagen (l) drei Paletten auf die jeweilige Palettenplattform (5) gestellt, diese schieben sich zusammen, der Hubwagen fährt ein. Jetzt gibt der Rechner die gespeicherten Werte frei und positioniert die Plattform (4) mittig zur Längsachse des LKW's. Nun schaltet sich der Laser (13) ein und führt den Hubwagen zuerst durch eine Schleuse (6), die die Aufgabe hat, schief gepackte Ladung wieder der 11reite des LKW anzupassen, danach geht es in den LKW. Da der Laser genau in der Mitte des LKW's entlangstrahlt, bewegt sich der mit einem Empfängergerät (14) ausgerüstete Hubwagen auch in der Mitte.The loading process: The gripper (7) moves to position I around a pallet (3), unfolds its rocker arms (7b), which are connected by bolts (7c) and lifts the pallet and transports it to position II. While this is happening, the position of the LI (W (2) is determined automatically. First it is determined by a Lifting device (8) jacked up and anchored so that it can also be used when shifting weight not moved. There are guide rods (9) unfolded on which light sources (10), hereinafter referred to as laser, are attached. Send to both sides of the truck the lasers cast their light on a semi-transparent mirror (all), which is a part straight forwards, the other distracts accordingly, so that two light-sensitive layers (12) that tell a computer the exact position of the truck. This calculator saves the values. The gripper is now in front of the three-forked pair Pallet truck (l) placed three pallets on the respective pallet platform (5), these push themselves together, the pallet truck drives in. Now the computer gives the saved Values freely and positions the platform (4) centrally to the longitudinal axis of the truck. so the laser (13) switches on and first guides the pallet truck through a lock (6), which has the task of adapting crookedly packed cargo to the width of the truck, then it goes into the truck. Since the laser shines right in the middle of the truck, the lift truck equipped with a receiver device (14) also moves in the Center.

Am Zielort angelangt setzt der Hubwagen ab und geht zurück zur Ausgangsposition.When it arrives at the destination, the pallet truck sets down and goes back to the starting position.

Claims

Claims: 1. Truck loading device for rear loading, thereby characterized in that the load from the removal point by means of a gripping system a remote-controlled three-fork-pair lifting truck is transferred and he takes the load transported in the jacked up truck.

2. Truck loading device for rear loading, characterized in that that the position of the truck is determined by guide rods on both sides be pressed against the truck.

3. truck loading device for rear loading, according to claim 2, characterized characterized in that parallel to the guide rods.

Light sources emitting focused light in an aligned manner are attached that hit light-sensitive layers and a computer the position of the truck that the platform carrying the pallet truck is centered on the truck's longitudinal axis aligns.

4. truck loading device for rear loading, according to claim 2, characterized characterized in that the bundled light rays partially through a semi-transparent Mirrors are deflected so that they are sensitive to two independent light Meet layers.

5. truck loading device for rear loading, according to claim l, characterized characterized in that the gripping system by means of pivotable rockers, the sicl. together connect, pick up pallets and transport them safely.

6. truck loading device for rear loading, according to claim 1, characterized characterized in that the remote-controlled three-fork pair lift truck is bundled by a Light beam is guided to the target location.
