Description

The invention relates to a printing device for an automatic machine for measuring the area and thickness of leather according to the author. St. JVb 109436.

The printers known for this purpose do not, by design, provide good transport of the measured leathers through the machine and high-quality printing due to the insufficient leveling of the skin area under the digital drum.

The described printing device, in order to more reliably transport measured, for example hard, leathers through the machine and improve printing quality, has a printing shaft with a cut along the length for more free passage of iodine to the skin, and it is mounted on a cantilever bracket and is shortened in proportion to the digital drum, as well as the spring-loaded cushion placed under this shaft, pressing the skin against the shaft during printing.

FIG. 1 shows a longitudinal section of the printing device; in fig. 2 - the same, top view.

The printing device uses a printing shaft / cut with a length for more free passage of skin under it, and it is mounted on a cantilever arm 2 and is shortened in length in proportion to the digital drum 3 and a spring-loaded rubberized roller 4 placed under the print shaft, pressing the skin against the shaft when typing.

140591-2 In the print shaft / mounted digital drum 3, spring-loaded digital drum clips 5 and a cam drive 6 for cocking the clips.

In the initial position of the printing shaft, the cut is positioned parallel to the surface of the table 7 of the machine and at a certain distance from it sufficiently for free placement in the resulting gap of the measured leathers.

The bracket 2 cantilever is attached to the frame 8 of the measuring machine. All other mechanisms of the printing device are mounted in the bracket.

The printing device operates in two cycles.

The first measure is a set of measurement results, the second measure is typing on the skin and resetting readings. When the measurement results are recalled, the voltage is applied to the coupling magnet 9, which operates and turns on the single-turn clutch 10. At the same time, rotation through the transmission system is synchronously transmitted to the digital drum 3 and the camshaft 11 with the cams 12.

When the camshaft rotates, its cams interact with the contacts 13, and the latter close the electrical circuits going to the electromagnets 14 to release the latch 5. As the camshaft 11 and the digital drum 3 rotate synchronously, when the electromagnets 14 are triggered, the locks 5, which fix digital drum on the required number.

In case of gauging data on the skin, the voltage is applied to a coupling magnet 15, which includes a one-turn clutch 16. Through the gear system, the movement is transmitted to the printing shaft.

When the shaft rotates / the one-turn clutch 10 for the entire cycle of operation of the printing device makes two turns: the first turn of the set of measurement results, the second turn simultaneously with the single-turn clutch 16 when printed on the skin.

The next skin, the exit after the area and medium thickness sensors through the transport shafts 17 and 18 of the machine, stops under the printing device. At this moment, the coupling magnet 9 is triggered and turns on a one-turn clutch 10. A set of measurement results occurs (for one revolution of the clutch 10), then the coupling magnet 15 is activated and the one-turn clutch 16 is turned on. At this, the printing shaft / begins to rotate, its cut touches the skin, and when spinning, the cylindrical part of the printing roll presses the skin against the roller 4 only on the region to which the figures are applied.

Due to this interaction of the printing shaft and the rubberized roller, the skin is leveled, transported, and the measurement results are printed.

At the end of the rotation of the printing shaft, the voltage from the coupling magnets is released, the one-turn couplings are turned off, and all the mechanisms of the printing device are returned to their original position.

Paint is applied to the digital drum and the readings are reset in the same way as in the known printing device.

Subject invention

A printing device for an automatic mask for measuring the area and thickness of leathers by ed. St. No. 109436, characterized in that, in order to more reliably transport the measured, for example hard, leathers through the machine and improve the printing quality,

It used a printing shaft with a cut along the length for more free passage of skin under it, and it is mounted on a cantilever bracket and made shortened in length in proportion to the digital drum, as well as a spring-loaded orezylenny roller placed under this shaft, pressing the skin against the shaft during printing.
