Description

Devices are already known for recording the operation of machines and machines in which the recording part consists of a series of electromagnetic writing mechanisms. These mechanisms are turned on and off when the machine is started or stopped using various contact devices that are locked to one of the moving parts of the machine being monitored.

In the proposed according to the invention the device used the above principle. Its feature is a device that includes a signaling device for a simple device only after a certain period of time after the mashina stops.

The presence of a certain pre-delayed activation of the signaling mechanism prevents the sending of false signals about a simple machine in the event of a brief stop associated with, for example, changing the workpiece.

In FIG. 1 and 2 are schematically, in two projections, the entire recording apparatus and FIG. 3- depicts a time-delaying fixture.

Clockwise or otherwise moving

mechanism using a gear system 1, 1 rotates the drum 2, on the surface of which the recording is carried out. The drum rotates freely on the fixed axis 3 and is provided with a device for its additional movement along the axis. g

For this purpose, clutch 4 is provided with a number of annular grooves. From the longitudinal movement along the axis, the drum is held by the spring finger 5, which enters one of the annular grooves of the sleeve 4. After one of the recording ends, the drum, after releasing the finger 5, moves along the axis until the finger enters the next groove. Thus, on the surface of the drum, several records parallel to each other can be alternately applied by the same marker.

Gears are selected in such a way that the time of one complete revolution of the drum corresponds to approximately 7 hours. The rotation of the latter is carried out using a finger 6 fixed on one of the gears and entering into a corresponding hole in the end part of the drum. Above the drum surface there is a row of writing nozzles 8, reinforced: x at the ends of the movable levers 9, in turn, connected to the core of the electromagnets 10.

The electromagnet is included in the circuit, closed by any contact mechanism, mounted directly on the controlled machine. In the absence of current, the tip of the electromagnet records a straight line. When the electromagnet circuit is closed, the pen rejects, giving an entry in the form of strokes perpendicular to the main line corresponding to the machine standby.

The pen 8 is inserted into the holder And, 12, in turn, hingedly fixed in the protrusions of the core 13.

In addition to the drum 2, the clock mechanism also rotates the auxiliary axis 14, on which a series of discs 15 are fastened, corresponding in the number of electromagnetic indicators available.

Each of these disks, shown separately in FIG. 3, consists of several washers 16, 17, 18, 19. Above each of the disks there are rollers 20, rotatably fixed at the ends of the corner levers 21, mounted on a common base 22, with the possibility of some lateral displacement. At the second end of the lever 21 there is a fiber roller 23, to which the ends of the contact springs 25 abut.

The device is as follows. As the drum 7 rotates, the pen draws a straight line on the paper around its circumference. If one of the working parts of the machine (for example, the caliper) is moved to cut the workpiece, the contacts close the current in the circuit of the corresponding electromagnet, the core will pull the measles, which will turn through a certain angle, thereby deflecting the pen to the side The machine chain is opened and the measles, under the influence of the spring 25, will be in place.

To signal a simple machine, the above described contact tool is used, consisting of a composite disk 16, 17, 18, 19 (Fig. 3).

In this case, 19 serves as a delay for the roller 20, and the washer 18 is provided with four skewed teeth.

When the axis 14 rotates, the roller 20 slides along the surface of the disk 15, and, depending on the angle of its rotation, the signal device (for example, a glow lamp or bell) turns on or off.

If the -20 roller is located on the washer 17, then the contact springs 25 move away from each other, and the lamp goes dead, but as the disk 15 rotates, the roller 20, in the next two or three minutes, hits the nearest bevel of the washer 18 and rises from there on the washer 16, which causes the contact to be closed by the springs 25, turning on the signal until the roller is again dropped from the washer 16 to the washer 17, i.e. after the corresponding machine has been started up.

When you turn on the monitored machine, the corresponding electromagnetic writing marker turns on, the end of the core of which drops the roller 20 from the washer 16 back to the washer 17, open the signal circuit. During continuous operation of the machine, the magnet of the electromagnet keeps the roller in its original position, preventing the signal from turning on. In the case of short-term switching on of the machine (for example, for rearrangement of parts or cutters), the signal does not occur, because due to the slow rotation of the disk, the roller does not have time to rise along one of the beveled washers 18. , then at that moment, when the bevelled portion of the washer 18 fits under the roller, the latter will move again to a certain angle, including the device signaling a simple machine.

The subject matter of the invention.

A device for recording the operation of machines and machines with the application of an electromagnetic writing mechanism activated by the working part of the machine during its movement, characterized in that to obtain a delay in time, in order to prevent a device that signals a simple machine to switch on during short stops, the following are used: rotating composite disk 15, fitted on top of a stack of bevelled planes and SLIDING around the disk circumference, and a lever 21 which is rotatably attached, used to close the signal pinch In the case when, under the presence of a periodic deflection of the marker box 13, the lever 21 under the action of the spring is displaced along one of the inclined planes to the protruding part of the disk.
