CS254357B1 - A device for converting an electronic signal into a mechanical movement of an active part - Google Patents

Abstract

The device concerns the conversion of an electronic signal from an electronic memory into a mechanical movement of the active part. The essence of the device is that the electronic memory sends a signal to the electromagnet, which moves the blade to a position in which it covers the hole in the arm of the two-arm lever. By covering this hole with the blade, the pin rests on the arm of the two-arm lever through the blade and deflects it. The second arm moves the active part. By suitable construction of the mechanical part and selection of suitable gears, any force on the active part can be achieved.

Description

BACKGROUND OF THE INVENTION The present invention relates to a device for converting an electronic signal into a mechanical movement of the active part by means of which any operation can be performed, such as punching, marking, shifting, embossing, and the like. shaft at a given moment for a linear working stroke.

The described process is applicable, for example, to the production of marking templates. Commonly used devices have punch magazines with all necessary letters, numbers and characters. The operator always searches for the necessary punch, places it or rotates it into the appropriate working position and by moving the lever punches the character and moves the template one pitch. The next worker starts the cycle again by searching for the necessary punch. All devices working on this principle are of relatively robust construction, bulky and impose physical demands on the operator, because the necessary force to perform the working stroke is generated by the operator.

These drawbacks are eliminated by the device for converting the electronic signal into the mechanical movement of the active part according to the invention. The device consists of a shaft with cams, which is driven by an electric motor. The cam track abuts the slide bearing. The carriage is provided with pins which extend into the holes in one arm of two arm levers, the other arms of which lie on the punches under which the punches are, the arm can also be connected to a mechanical feed. Above the openings in the arms of the two-armed levers are the foils, which are hung on the solenoid beams, which are connected to the electronic memory with the keyboard.

Using electronic memory with the keyboard simplifies operation by just pressing a key on the keyboard.

All other operations are performed automatically by the operator without operator intervention. Punches a character, moves the template one pitch, and waits for the next keystroke to press the next character.

An exemplary embodiment is shown in the accompanying drawings

Fig. 1 shows the idle run, Fig. 2 shows the moment when the electronic memory gives an electromagnet signal and Fig. 3 shows the moment when the slide has been connected.

The device for converting the electronic signal into the mechanical movement of the active part according to the invention is formed by a shaft with cams 1, which allow the carriage 2 to move forward and back. The cam track bears on the slide bearing 2, which are provided with pins. These extend into the holes in one arm of the two-arm levers 4, whose other arms lie on the dies 5 under which the dies 9 are. hinged on the solenoid beams 6, and these are connected to the electronic memory 10 with the keyboard.

An embodiment of the invention converts the electronic signal from the electronic memory 10 into a mechanical rectilinear movement of the active part of the punch 5 so that the start of the electric motor starts to rotate the shaft with the cams 1, which move the slide 2 forward and backward. This movement is constant until the electric motor is switched off after the work is finished. At that moment, by pressing the key of the electronic memory key 10, a signal is given to the electromagnets 6 which switch on and pull the rocker arms 7, at the ends of which the springs with the foils 8 are suspended. By this movement, the foil 4 covers the holes in the arms of the two-arm levers 4 through which the pins 2 have so far been freely passed. by cutting through the template.

The described process of the present invention completely eliminates the physical strain of the operator and is applicable to all devices where operations from electronic memory are converted into linear motion with the need for greater forces. The construction is undemanding in size, works smoothly without impacts, starting and stopping the motor.
