Description

Entry arm for loading devices It is known to have a horizontal sliding retractable arm to use in the. Levels of a loading frame stored material plates and possibly also the loading plates in pushing the floors of a press.

It is customary to arrange the loading frame so that it can be raised and lowered as far as possible, that one is from a loading table located below the lower edge of the retraction arm can slide the material plates into the loading frame.

Sometimes it is due to the height conditions that the loading table is in a higher position or in front of the loading rack in the storage rack, from which several material panels are moved into the loading frame at the same time Need to become. The loading arm in between prevents it from being pushed in. the plates in. the loading frame. According to the invention, the retractable arm so briefly stated that it does not hinder the retraction of the material plates, and is provided with a vertically movable or foldable extension, which makes it possible, when retracting, all material panels lying in the loading frame capture.

In a further embodiment of the invention, the retractable arm is with a Device provided, which the extension of the retractable arm automatically before Retraction of the arm downwards and extends again when the arm goes back pulls in automatically.

The drawings show exemplary embodiments. In Fig. Z is a. the Entry arm that can be moved on track b. The arm is so short that the material plate lying on the loading table c is placed on one level of the loading frame d can be inserted. By lifting and Lower the loading frame you can bring .alle floors of the loading frame d in front of the loading table c and to fill.

An extension e is attached to the retractable arm. This is after can be extended from below and is guided in guides f.

In the retracted state is the space between the loading table c and Loading frame d free and allows the transfer of material panels into the Loading rack d.

In the extended state of the extension e, the retracting arm a, along with its extension e, can grasp all of the material panels stored in the loading frame and push them into the floors of the press (not shown) as it travels on the roadway b.

Fig. I also shows an automatic drive for the extension and Retraction of the extension e. This can be rotated with one leg on the retraction arm mounted lever g connected. The other leg of the lever g is with the pull chain dt connected, which is used to move the retraction arm.

If the lower part of the chain h moves to the left, it rotates the lever g to the left and extends the extension e downwards. Once the Lever comes to the stop i, the retraction arm cc is taken and pushes the Material panels atle @ r floors in the press.

If the chain h moves to the right, the lever g also rotates to the right and pulls the extension e back and moves the retractable arm into its Starting position.

The Fig.2 @ shows another embodiment.

Here, a storage rack k is arranged in front of the loading rack c. Beil retracted extension e can be seen in the storage rack k Push material plates into the loading frame c and also others from the Material plates coming from the production machine through the storage rack run into the loading frame c.

When the extension e is extended, all can be placed in the loading frame Grasp lying material plates and push them into the press.

The retraction arm is moved by a Motor transmission 1, the pinion of which engages in a rack lying on the track b.

The extension e is extended and retracted by the motor gearbox m.

The way it works is as follows: A push button turns the motor gearbox m put into operation and the extension extended. Wind at the end of its stroke it is automatically shut down and on at the same time: the switch is actuated, which the Motor gearbox 1 in: operation starts. This leaves the retractable arm in the loading frame retract and push the material panels from the loading frame into the press.

The backward movement is effected by a push button or automatically by a switch, which the motor gear L and m in reverse moves and the extension goes back.

The Ahb. 3 shows a further embodiment. Here is the loading table arranged at the same height as the lowest level of the loading frame in the highest position. The retraction arm a. is therefore only about the. The height of one floor has been shortened and one that can be folded down Extension provided, which is rotatable with a horizontal axis and at Unfolding the space between the loading table and loading frame releases. As in the previous examples, the extension e, when the retraction of the in the loading frame d stored plates are to be placed in the press, folded down so that all material plates are recorded.

When the loading arm moves back, the extension e becomes again Folded up to enable new panels to be fed into the loading frame.

The unfolding and folding down of the extension e takes place automatically through the horizontal movement of the arm, in the following way: The extension e is connected by a linkage to a lever o, which carries a roller p at its tip and the extension by a counterweight e hochidappen. When the retracting arm a moves back, the roller p runs on the rail q and passes over a switch r at the other end, which snaps up after being driven over by a counterweight or a return spring. When the retraction arm a moves forward, the roll is depressed by the now upright switch r, and the extension e folds into a vertical position.

Claims (2)

PATENT CLAIMS: i. Retractable arm for the insertion of material panels from a liftable and lowerable storage rack on the floors. a press, characterized in that the push-in arm is provided with a liftable and lowerable or hinged extension which, in the retracted state, allows material panels to be transferred from <<the loading table to the loading frame, and also allows all material panels in the extended state to capture and to transfer from the loading frame in the floors of the press. 2. retraction arm according to claim i, characterized in that _that the extension and extension move in and out automatically with a backward movement of the retraction arm is connected.
