/ Fiz. The invention relates to mechanical engineering, in particular to devices for metal forming. According to the main author. St. No. 919777 discloses a branding device comprising a tool holder mounted on the corns with a set of tools placed in a raster, a tool changer mechanism and an adjustment system having interconnected photo-reading unit, encoder, decoder and driver. In this case, the tools are made in the form of chisels, and the mechanism of the tools is made in the form of pneumatic impactors located in the casing with a number of chisels with magnetic valves associated with the control system, which contains a pre-set nanoel and a switch associated with the encoder and driver .m commands 1. However, the known device has a disadvantage, due to the loss of performance due to the need for stops for visual quality control of the brand. The aim of the invention is the elimination of stops l.1 of visual control, and, consequently, of new productivity of ways to automate the control of stamps (without stopping the device). This is achieved in order. that the device d.-1 of the brand, the system (s) (van1p 1e and the body kleymod) press, with a set of tools exchanged in a vnde raster, the mechanism for changing tools and tools, kmsh, are interconnected (|) otpchptyvayu1 block, i1frator. de1nn (() rat () p and (command shaper, with this. tools were punched in the form of chisels, and the mechanism of tools was 1) .1 fox in the form of non-impact knobs in the case with the number of chisels with magnetic clans. The Uni-Aviation system, which contains nap.P., a pre-1 character set and a switch connected to the encoder and command generator, is equipped with an optical sensor, (|) () with a comparator with a CxeMoii comparison code, with an optical coitro sensor. .1 in the form of light emitting in pairs infrared wavelengths and photodetectors, optical axis of the light output, chuchatellei and photon-receivers are tilted at the same angle to the normal m, nural.yuliy.m axes of the chisels and offset from them by a distance multiple of the marking, and the photomultipliers are connected to the inputs of the former The comparison circuit is connected by its inputs to the code generation outputs and to the command generator outputs, and the output of the comparison circuit is connected to the input of the command generator. 62 In addition, the Optical Control Sensor, 1 is equipped with an additional light emitter and photo receiver, which are arranged to optically monitor the surface of the product. FIG. I shows a device for branding with optical monitoring sensors, general view; in fig. 2 - the same, bottom view; in fig. 3 shows section A-A in FIG. 1: in FIG. 4 shows a section BB in FIG. 2; in fig. 5 is a block diagram of the device; in fig. 6 - functional scheme of the control system. The device for glue.men contains chisels 1 7 (Figs. 1, 2 and 3) installed in the naravl of the holder of the holder 8. The stileholder 8 is fixed to the cord 9 of the device for the brand, in which the actuators (solenoid valves) are located, which provide pneumonia. Moudarnika.mi, acting on me chisels 1-7. To the body of the holder 8, on the rear side but not to the direction of its direction, is attached, screws 10 are attached to the case of the optical control sensor 11 (its rigid connection can be provided in another way, for example by welding). The outermost one (the sensor 11 of the sensor 11) lies in the compartment's dividing line formed by the working edges of the chisels 1-7, or parallel to it. In the through holes of the sensor housing 11 there are 7 optical pairs of optical pairs (Fig. 2), each of which consists of a light color 12 and the photodetector 13. The optical axes of the light emitters 12 and the photon reflectors 13 coincide with the axes of the holes. The axes of each pair of holes (a-c and v-b in Fig. 4) are located in planes perpendicular to the base of the sensor, together with normal n 1-n 7, which are parallel to the axis of the chisels 1-7 and are separated from them, respectively at a distance that is a multiple of the tag, in the direction opposite to that of the retainer 8 (p 1 is located at a distance L from the axis of the chisel 1 (Fig. 2) and n 2 from the axis of the chisel 2, etc.). The immobilized axes are inclined at an angle of the axis to the normal m n 1 - n 7 and intersect with them on the surface of the marked product 14 located under the sensor 11 (Fig. 4). This thereby provides an optical link between the light emitters 12 and the photomultipliers 13 with prints 15 from chisels 1-7 on the product 14. In the sensor housing 11 (FIG. 2) there is an additional optical pair consisting of identical mentioned light emitters 12 and a photodetector 13 located in openings whose axes lie in the same plane with the normal n 8 equidistant from the normals n 3, n 4, n 5, n 6, and tilted to it at the same angle, intersecting on the surface of the marked product 14 located under the sensor 11 (other variants of positioning the additional pair are possible provided that it is only possible to be optically connected with the surface of the product). The photodetectors 13 of the sensor 11 (Fig. 5) are electrically connected through the shaper 16 of the code and the comparison circuit 17 with the driver 18 of the commands of the program control system, and the light emitter 12 with its power supply unit.

Light emitters 12 and photodetectors 13 are standard semiconductor devices made in cylindrical housings, x, whose optical axes coincide with the axis of the body.

The code generator 15 is an analog device for amplifying and subtracting electrical signals.

Code Comparison 17 17 is a logical structure for comparing codes.

The command shaper, which is part of the software control system 18, is a memory and logic device that generates chisel operation control signals and signals for reading information from the program carrier and moving the holder to pag.

The photodetectors 13 of the sensor 11 are electrically connected to the inputs of the imaging unit 16 code, the outputs of the imaging unit 16 code are connected with a part of the inputs of the comparison circuit 17, another part of the inputs of which is connected with the output of the imaging unit 19 of the program control system 18, the output of the comparison circuit 17 with the input of the imaging unit 19 commands of the program control system 18, and the light emitters 12 are connected to the source 20 of the power supply of the program control system 18. The control system also contains a serially connected photo reader 21, a decrypt a rator 22 and an encoder 23 connected to the input of the command driver 19, as well as a pre-set panel 24 and a switch 25 connected to the encoder 23.

Mentioned mechanical, optical and. the electrical connections allow the automatic quality control of the marks applied to the device processing for the branding marks.

Device for glue. Change with the sensor optical control works as follows.

The marking information from the program carrier is stored in the memory of the driver of the command system of the program control system 18 as a combination of "n of seven" signals. These signals, in the form of a seven-digit code, arrive at a part of the inputs of the comparison circuit 17, and also carry out

the inclusion of the Executive bodies located in the housing 9 of the device and o6t4i baking reciprocating movement of the chisels along their axes when applying one or another sign. For example, if there is code 1011101 in the memory of the application of marks, chisels 1, 3, 4, 5, and 7 take part, which leave on the product surface 14 five prints 15 stylized marks (uiuji0 pa 2) formed by the working edges chisels 1-7 (fig. 1 and 3). After recording the memory of the instruction shaper of the system 18 of the programmed control of the code of the character being printed, a command for marking is formed. At this command, the executive ojMaiibi of the housing 9 of the device acts on the chisels I 7 corresponding to the code in the memory, ensuring the application of the sign given by the program. The optical sensor 11, at the time of filling the first character, is above the surface of the product 14, still ic marked, therefore the photodetectors 13 register low level signals corresponding to the reflection of the fluxes of light emitters 12 from the iioBeiixnocrn product and equal to the signal from the photodetector of the additional optical pair. Si1n;: ly from the photodetectors 13 enter the shaper 16 codes and are amplified in letters. The signal i from the photodetector of the additional pair ni i is read from the signals of other photo-receivers: -,

0 kov and at the output of the format I) of the code there appear difference si | | - lines of the level of a logical zero (log. "O), forming the code 0000000, which corresponds to the absence of fingerprints of 15 characters under the sensor.,

After the end of marking

The 5 characters of the command generator of the software control system 18 generate signals for reading information about the information server about the km from the program carrier and for moving the holder 8 to Hiar.

After the carrier has been moved to the schag and written into the memory of the former, the 19th team of Comand. The software system of the next code point code 18 is formed by a command to mark the second character. At the same time, optical pairs of light sources ..

 12 and the photocensors 13 are na.L with the first mark applied, and the photodetectors 13 above the fingerprints 15. register a high level signal. Photodetector extra optical

still registers the signal of the 1st level.

The amplified difference signals at the output of the imaging unit .16 of the code of the system 18 of the multimedia control form in this 5 case a code different from the code 0000000. For example, when there are 15 fingerprints under the sensor 11 15 digits 2, the output of the imager 16 of the code is 1011101,

which corresponds to high level signals from five photoirissors 13 and 11: a double level from doors.

in the scheme, 17 comparisons of the stake from the stake former 16 is compared with the stake stored in the memory of the former of the command system 18 of the program control (per nerve mark). When Koioii coincides, that is, about: 1 means the device is marked with a sign, - corresponding to a common nano-mode and a system, automatically marking and disappearing.

If the coas are not combined, which means applying a sign to an inconsistent program or an insufficiently high-quality print of it on the product surface, the output from the comparison circuit 17 sends a signal to the command generator of the control system 18 to interrupt the automatic operation of the device and to identify the cause of the failure.

Equipping the phase object with an optical control sensor allows you to automate the marking process according to the program, increase productivity, eliminate scrap and use the device in automated production lines of a number of productions.

This ensures the effectiveness of using this branding device.
