SU1328855A1 - Actuator for switch - Google Patents

Abstract

The invention relates to electrical engineering and can be used to provide a signal in any control system when the transported object moves in the forward and reverse directions. The aim of the invention is to increase reliability and improve operational performance. The flexible rods 8 are inserted into one and 5 shoulders of the two shoulders lever 5, onto which the adjustable stops 6 are fixed. By means of these stops, the lever 11 acts on the switch 3 when the object is transported onto the flexible rods 8. 2 Cp. F. J (L with N3 oo 00 ate SP

Description

The invention relates to electroforming. It is intended to feed a signal to an automated control system about the passage of a transported object through a certain zone and can be used to give a signal in any system. control, in particular, where different triggering times of the switch contacts are required when the transported object moves in the forward and reverse directions.

The aim of the invention is to increase the reliability and enhancement of the functionality by separately controlling the timing of the operation of the switch during the forward and reverse movement of the driving part.

Fig, 1 shows the drive, a general view; 2, the same top view; figure 3 - section aa in figure 2,

The actuator includes a housing to which a switch 3 is attached with screws 2, and an axis 4 on which a double-arm lever 5 is mounted for rotation, on which, at diametrically opposite points, are adjustable stops 6 (screws) with lock nuts 7. In one of the arms of lever 5 Inserted flexible rods 8, forming a resilient element. Flexible rods are fastened with a yoke 9 with a screw Yu. The lever 11 is rotatably attached to the case by means of an axis 12 with a nut 13 and a washer 14. The case is attached to the element of the transport device by means of a bar 15 and two screws 16 with nuts 17.

The drive switch works as follows.

When an element of the transported item 18 is hovered, the elastic element formed from flexible rods 8 rotates a double-arm lever 5, which by means of one of the adjustable stops 6. presses lever 11, which, turning around its axis 12, presses the switch roller 3. Upon further movement of the transported item 18, the elastic element is elastically deformed and passes the transported item 18.

In order to adjust the moment of operation of the contacts of the switches, it is necessary to screw in or unscrew the corresponding adjustable stop 6, depending on what

required — advance or delay in signaling to control system.

When moving the transported object 18 in the opposite direction, the drive works in the same way, only another adjustable stop 6 takes part in the work and the other two shoulders lever turns in the opposite direction.

The proposed drive is compact, easy to manufacture, and allows separately adjusting the moment of contact of the switch when moving a moving object in the forward and reverse directions by simply screwing or screwing the adjustable stops using a screwdriver, does not require high accuracy of placing the moving object on the transporting body in direction perpendicular to the direction of movement, as in any case ensures a reliable contact of the moving object with the drive lever and reliable Achu signal to the control system. The drive has a high degree of reliability due to the simplicity of the design and duplication of parts, the breakdown of which is most likely. By means of a drive, the inertia of the transported object and transporting body can be taken into account.

Claims (3)

Invention Formula 1, the actuator for the switch, containing two levers, each of which is mounted on an axis can be rotated, while an adjustable stop is placed on one of the levers, in order to increase reliability and enhance functionality by means of a separate controlling the moment of operation of the switch during forward and reverse movement of a moving object, it is provided with an additional adjustable stop, which is located on the same lever as the first adjustable stop, with both adjustable stops set to the lever on one side of its axis of rotation with the possibility of acting on another lever, which is installed with the possibility of acting on the switch. 2. The drive pop. 1, which differs from the fact that one of the arms of the lever, carrying adjustable stops, is equipped with an elastic element. 3. The drive according to claims 1 and 2, which is based on the fact that 77. the element is made of flexible rods. sixteen 13 74 / 1e / S N & F - // 7 T FIG. 2 Editor O.
