Abstract

This invention relates to the printing industry, in particular to marking devices. The purpose of the invention is to improve the quality of marking. The automatic marking device comprises a housing, a plate holder, a mechanism for reciprocating the holder to be moved in a direction perpendicular to the movement of the ink carrier, a mechanism for feeding the ink carrier and an actuator. In this case, the mechanism of reciprocating movement of the plate holder in the direction perpendicular to the movement of the ink carrier has a sleeve with a truncated spherical shank and an axial bore. A spring-loaded pusher is located in this hole. The stile holder is detachable, in two parts. One part is loosely mounted on the shank of the hub and has an internal spherical surface in contact with the corresponding spherical surface of the shank. In the second part, a replaceable stamp is installed and it has the ability to interact with the spring-loaded pusher. 1 il.

The invention relates to the printing industry, in particular to the labeling of products.

The purpose of the invention is to improve the quality of marking.

The drawing shows the device, the overall appearance.

The device contains a pump 1, made in the form of a bracket, with a crosshead 3 mounted on it by means of sleeves 2 with two guides 4 and 5, on which brackets 6 and 7 are fixed. On the latter, there are coils 8 and 9 with printing foil 10. Coil 9 is equipped the actuator 11, to which the foil displacement sensor 12 is electrically connected; The sensor 12 interacts non-contactly with the protrusions 14 placed on the roller 13. On the guides 4 and 5 of the crosspiece, the holder 16 is fixed to the membranes 15 by means of a pin 17 and nuts (not started) the sleeve 18 is fixed, which contains the rod 19c by the tail 20 in the form of a truncated sphere on which one of the holder holder parts 16 is mounted with its spherical surface 16, the other part 22 of which is fixed to the first (21), for example, with screws, plate heater 23 in a mica shell On the second (removable) part 22 there is a plate 24 with pressure plates 25 for fastening plate stamps 16, the spherical end of the plunger 26 is connected to the center of the sphere of the shank 29, which is pressed to the second part (22) holding ate stamps 16 the spring 27 with a screw 28, which provides not only the VI

installing the stamps 16, but also preserving the memory of the position of the surface of the product (the previous one), as a result of which the stamps 16 do not slip when marking, thereby improving the quality of the marking.

To communicate the oscillatory movements of the stamps 16 on the sleeve 18 is fixed ha ha 29 with a bark 30. And on the traverse 3 there is an electromagnetic vibratory actuator 31. To automate the marking process on the housing 1, the pneumatic cylinder 32 is installed with the ability to control the stroke, the springs 33 of the traverse 3 are mounted to the rod. Under the stamps 16 are located cyclically rotating rotor 34 with grippers 35, as well as a feeder 36 with articles 37.

To ensure the position of the printing foil 10 relative to the stamps 16, regardless of their turn from the shape of the marked products 37, and to eliminate burning the foil before pressing it to the product, the device contains rollers 38 that are slightly offset (by 1-3 mm) relative to the stamps towards the products 37.

In order to enable adjustment of the required linear movement of the foil 10 depending on the size of the marks of the stamps 16, the roller 13 is made of an elastic (rubber) sleeve 39 under which plate-shaped lugs 40 are arranged radially around the circumference of the roller 13. The lugs 40 rest on the conical the surface of the sleeve 41 interacting along the end with a nut 42 mounted on the axis of the roller 13. The projections 14 are made of a set of plates with a thickness of 0.3 mm fixed on the end of the roller 13 with the possibility of their angular displacement between them.

The device works as follows.

From the drive (not shown), the rotor 34 receives a cyclic rotation. By its grippers 35, the rotor 34 picks up one product 37 from the feeder 36 and moves it under the stamps 16, after which the actuator (pneumatic cylinder 32) turns on, which moves towards the rotor 34 the yoke 3 with the brackets 6 and 7 located on its guides 8 and 9 with foil 10 and membranes 15c with sleeve 18 and stamps 16. At the same time, vibrator 31 is turned on. Stamps 16 enter with vibration through foil 10 into surface 37 of product, press foil 10 against product 37. and article 37 - to rotor 34. At This traverse 3 and the sleeve 18 a few more (1-2 mm) continue t move, and the stamps 16 and the pusher 26 stop moving. The spring 27 is compressed and creates the necessary force for transferring the image of the characters on the stamps 16 to the surface of the products 37. The contrast of the characters is provided by the printing

foil, and an increase in adhesion properties is achieved by heating from an electric heater 23 with vibration at a frequency of 50 Hz. i.e. by dynamically repressing paint. The quality of the marking is improved, and the effort and time of the marking is reduced.

After finishing marking one product 47 (0.5-1.5 s, depending on the size), pneumatic cylinder 32

5 is turned off, the springs 33 return the yoke 3 to its original position. Before the stamp 16 departs from the product 37, the spring 27 expands and, through the pusher 26, prevents the initial position of the part from returning

0 21 brackets 16, the rod 19 moves upwards A gap is selected between the spherical surfaces of the shank 20 and the corresponding part 21 of the brackets 16, with the result that

5, the upward movement of the stem 19 at the moment of the withdrawal (detachment) of the stamp 16 from the product 37 ensures that the position of the stamp 16 is reliably fixed relative to the surface of the product 37, i.e. the memory of the RGO position is fixed.

At the moment when all elements of the traverse 3 return to the initial position, the actuator 11 is turned on, the coil 9 starts to spin, and the foil 10 moves, winding on

5 coil 9 to the input of the groove of the contactless sensor 12. 14, that is, one step equal to the value applied to the product by the Vion MI ADU by the seal 14 can be changed into the dependent KI IT pitch (the number of marks) the Sensor 12 is turned on and dao g - vaii / iy hm drive 11 t p process termination, removal of foil

In order to mark other parties (size 0, the axial movement of pneumaticylpdree 32 in coppus 1 is set to 0 ° traversing the initial position of crosshead 3. On plate 24, clamps 4 2E fix new stamps 16 and change the angular spacing between the projections 14 on roller 13

The whole process is carried out automatically. Improving the quality of marking is achieved by eliminating slippage of the stigma containing when changing the Formation Form. curvature, etc.
