Abstract

The invention relates to a press machine for the production of motor vehicle signs. All embossing plates (item 2) are guided together from one direction into the hydraulic press (item 1) and removed again.

Description

The invention relates to a press machine for the production of motor vehicle signs, which has a frame in which an embossing tower is formed, in which a magazine with compartments is arranged and which includes a press.

A press machine of the aforementioned type is, for example, from the DE 196 12 831 C1 known. With their help, for example, license plates are produced in which a blank is conveyed under a press, which subsequently imprints the previously selected symbol in the form of letters, numbers or the like in the blank. The embossing is usually done by a hydraulic drive.

Object of the present invention is to improve automatic presses of the type mentioned. According to the invention, this object is solved by the features of claim 1, characterized in that the compartments are each connected to a torsion-proof shaft.

With the invention, a press machine for the production of motor vehicle signs is created, which improves the known automatic presses. The use of the anti-rotation shafts has the advantage that the compartments do not tilt during their horizontal movement. Thus, the reliability of the press machine is improved.

In an embodiment of the invention, the frame is formed from profile tubes, which preferably form resting on the floor linear guide rails. The use of the linear guide rails has the advantage that they allow a release of the frame of the press machine. As a result, the possibility is advantageously created to move the frame with the embossing tower and thus to remove from the hydraulic press, which greatly facilitates the accessibility and verifiability of the provided in the embossing tower magazine, especially during maintenance.

Other developments and refinements of the invention are specified in the remaining subclaims. An embodiment of the invention is illustrated in the drawing and will be described in detail below. Show it:

1 the side view of a hydraulic press;

2 the top view of a hydraulic press with vehicle shield introduction;

3 the schematic representation of the plan view of an embossing tower according to the invention with insertion unit;

4 the schematic representation of the side view of an embossing tower with plug-in unit;

5 the schematic representation of the top view of the stamping tools with a motor vehicle sign.

The selected as an embodiment press machine has a frame 20 from profile tubes. The profile tubes form on the one hand on the floor resting linear guide rails 21 from, on which the press machine is arranged; On the other hand, they form vertical profiles 22 which form a frame for the automatic press. In the frame 20 is an embossing tower 23 trained in which a magazine 25 is arranged.

The automatic press includes a hydraulic press 1 , This has on one of its longitudinal sides a license plate insertion 3 in the form of a drawer ( 2 ). On one of the long sides of the drawer is a one-sided driven introduction 10 intended for the drawer; on the other long side is a one-sided roller bearing 11 intended for the linear guide of the drawer. In addition, the introduction points 3 a guide rod 12 on.

In the hydraulic press 1 are two hyphens 13 arranged, one of which is formed positive in the embodiment, and the other forms the associated negative ( 1 ). The negative trained hyphen 13 is located in the letter / number embossing tool 2 the hydraulic press 1 ,

The letter / number stamping tools 2 are with the magazine 25 connected. In the embodiment are in the magazine 25 each twenty-six vertically stacked levels 26 intended for recording letters and / or numbers. At the same time in the embodiment seven subjects 24 arranged to receive letters and / or numbers horizontally next to each other. In this way, it is possible to press license plates with seven digits and / or letters.

Each of the horizontally juxtaposed compartments 24 in the magazine 25 is with a torsion-proof shaft 7 connected. The torsion-proof shafts 7 are at theirs the magazine 25 opposite end with a push-in gripper 6 connected, which is part of a plug-in unit 5 is. The push-in gripper 6 is on his magazine 25 facing side with seven L-shaped hooks 27 provided, which are all aligned in the same direction. The plug-in unit 5 with the push-in gripper 6 serves the horizontal movement of the magazine 25 arranged letters and / or numbers in the area of the press 1 ,

In the manufacture of license plates is a - not shown - sign blank by the operator on the vehicle sign-insertion 3 put on and horizontally in the direction of the arrow 8th in 3 along the linear guide 11 or the guide rod 12 in the hydraulic press 1 introduced. Then they are in the magazine 25 letters or numbers selected by a PC-based system. The trays provided in the magazine are then vertically in the direction of the arrows 9 in 4 until the selected letter or number is in the plane of the insertion gripper 6 is positioned. If this selection is carried out in all seven compartments, all embossing tools are put together in the hydraulic press 1 promoted. The embossing is done by a hydraulic stroke. After the embossing process, the withdrawal of all embossing tools 2 from the hydraulic press 1 in the vertically arranged embossing tower 23 , This process is carried out with the help of the push-in gripper 6 , In order to ensure a safe withdrawal, the torsion-proof shafts find their way 7 Use. Trained as a drawer vehicle sign introduction 3 is then withdrawn horizontally and removed the sign blank. The process then begins again by placing a new sign blank by the operator.

With the help of vertically stacked embossing tools 2 It is possible to characterize a variable sequence of different letters and number sequences in the motor vehicle sign. By the drive is an adjustment of the vertical position of the embossing tools 2 reached. This is done by the horizontally oriented, non-rotating shafts 7 through the gripper 6 be moved. The embossing tools 2 are the same design and are fixed by holding magnets.

The selected embossing tools 2 be simultaneously as a unit in the hydraulic press 1 through the plug-in unit 5 including the push-in gripper 6 promoted. All embossing tools 2 come together from one direction in the hydraulic press 1 in and out. There is an automatic embossing of letters and numbers on the single sign and that together from one direction. With the automatic press according to the invention letter and number embossing can be made in single-car signs.
