Abstract

The marking device for marking packaging material with a mark, the date of filling, consists of a support plate with a carrier on which the embossing tape is wound. The embossing tape is guided under the heated body with punches between the feed and pressure roller on the carrier. In the space under the punches, there is a packaging film between the embossing tape and the stop. A feed electromagnet is also attached to the support plate. The electromagnet presses the heated body with punches over the embossing tape onto the packaging film.

Description

The invention relates to a device which marks the packaging material with a mark, a filling date, etc.

The mechanical marking devices used hitherto are very complex to manufacture and difficult to adjust. Pneumatic marking devices have high energy consumption and high purchase price. In single-solenoid marking devices, the step size can not be precisely adjusted when the punching lever is moved, making it uneconomical to use.

The aforementioned drawbacks are solved by the marking device according to the invention. SUMMARY OF THE INVENTION The object of the invention is to design a marking device comprising a support plate vertically mounted on a packaging machine structure, on the front and rear side of which a carrier, a roller, a feed roller and a lever are rotatably mounted. A thrust roller is mounted on the lever pin and is spring-pressed against a feed roller on which the freewheel is fitted. The freewheel is connected by a belt to the carrier and by means of a clutch and a double-reversible lever to the core of the feeding electromagnet. A brake, a stop screw and an electromagnet are screwed to the carrier plate, the core of which is firmly connected to the heated body with punches. A stop is attached to the butchers.

Such a marking device is characterized by high durability, easy adjustment, minimal maintenance and low energy consumption. During its production there will be considerable savings of laboriousness compared to existing types. By equipping the packaging machine with a marking device according to the invention, the utility value of the packaging machine will be substantially increased and thus its marketability and competitiveness will be increased.

In the accompanying drawings, in Fig. 1 the marking device is shown in a front view, in Fig. 2 the marking device is in a rear view.

An exemplary embodiment of a marking device according to the invention, eg for packaging machines of the BTH 40 series, consists of a carrier plate 1 in which a carrier 2a is rotatably mounted on which a punching tape 3 is wound. The punching tape 3 is guided by rolls 4a, 4b, 4c under the heated body 5 with punches 6 between the feed roller

Claims (1)

Marking device, in particular for packaging machines, characterized in that it consists of a support plate (1), on the front and rear side of which the grippers (2a, 2b), the rolls (4a, 4b, 4c) and the feed roller (8) are rotatably mounted and a lever (13) on whose pin (12) a pressure roller (9) is mounted, on which a freewheel (19) is attached, connected by a belt (20) to a carrier (2b) and by means of a clutch (18) and double-reversible 8 and the pressure roller 9 on the carrier 2b. The pressure roller 9 is mounted on the pin 12 of the lever 13 rotatably mounted in the support plate 1. The lever 13 is also connected to the support plate 1 by a spring 14. In the space below the punches 6 there is wrapping foil 10 between the stamping tape 3 and the stop 7. it is connected to the core 15a of the electromagnet 11, which is fixed to the support plate 1. A feeding solenoid 16 is also attached to the support plate 1, with the core 15b of the double-return lever arm 17. The second leg of the double-return lever 17 is coupled by a clutch 18 19, mounted from the rear of the feed roller 8. The feed roller 8 is connected by a belt 20 to the carrier 2b. A stop screw 21 is positioned opposite the core 15b of the feed solenoid 16. A brake 22 is attached to the support plate 1. The marking device according to the invention operates as follows: the electromagnet 11 presses the heated body 5 with the punches 6 over the embossing tape 3 on the packaging film 10 and the stop 7. This marks the packaging foil 10. When the electromagnet 11 releases the embossing tape 3 16 against the stop screw 21, which adjusts the amount of displacement of the embossing tape 3, depending on the size of the punches 6. The freewheel 19 with the feed roller 8 is rotated by the reversible lever 17 and the coupling 16. On which the worn embossing tape 23 is wound. The spring 14 presses the pressure roller 9 against the feed roller 8 by means of a lever 13 and thus ensures a constant displacement of the embossing tape 3. On displacement the embossing tape 3 unwinds from the carrier 2a on which the brake 22 acts. forming a loop on the embossing tape 3. The marking device according to the invention can be used in all types of packaging machines in which the packaging is formed from the roll of packaging material, i.e., in the case of tubular packaging machines, or in others, for example for group packaging. The marking device according to the invention is used wherever a clear marking of the individual packages is required, e.g. a lever (20) with a gripper (2b) and by means of a clutch (18) and a double-reversible lever (17) with a core (15b) of a feeding electromagnet (16) attached to the support plate (i) to which the brake (22) is screwed a screw (21) and an electromagnet (11), the core (15a) of which is fixedly connected to the heater (5), to the punches (6), and a stop (7) is fastened to the punches (6).
