专利摘要:
A printing machine such as a stencil duplicator having an ink supply roller and a squeezer and adapted to hold a columnar ink deposit placed on the outer peripheral surface of the roller and substantially prevented by the squeezer from moving as a whole together with the outer peripheral surface of the roller, including a device for detecting the amount of ink in the ink deposit, having a pivotable lever whose one end contacts the ink deposit and which changes its pivotal position in accordance with the size of the ink deposit, and a means for detecting the pivotal position of the lever.

专利说明:

The invention relates to printing, in particular to ink machines of printing machines and their devices for controlling the amount of inks.
A device for controlling the amount of ink in an inking apparatus of a printing machine is known, which contains means for supplying ink to the wedge-shaped space formed by the surface of the ink supply roller and the pressure element regulating the thickness of the ink layer on the transfer roller mounted on the axis. Parallel to the axis of rotation of the ink supply roller, a pivoting lever and a microswitch placed on the path of movement of the pivoting lever are connected to the paint supplying device in the wedge-shaped space. changes in the volume of paint 13.
However, the known device is characterized by a lack of reliability due to the fact that it is difficult to catch the moment of the beginning and cessation of paint supply in the wedge-shaped space.
In addition, a local deformation of the diaphragm is possible, which can disrupt the operation of the pivot arm,
The purpose of the invention is to increase reliability. devices for adjusting the amount of ink in the dyeing apparatus.
The goal is achieved by the fact that in a device for adjusting the amount of paint in the ink apparatus of a printing machine, there is a means for supplying paint to the wedge-shaped space formed by the surface of the paint-supplying roller and a pressure element regulating the thickness of the layer of paint on the paint-supply roller mounted on an axis parallel the axis of rotation of the roll-forming roller, a pivoting lever and a microswitch placed in the path of movement of the pivoting lever. associated with the means for supplying paint to the wedge-shaped space, the end of the pivot arm is placed in the wedge-shaped space in the p-position area of the volume of paint supplied by the paint supplying agent.
FIG. 1 shows a diagram of a device for controlling the amounts of ink in a dyeing apparatus of a screen printing machine in a position where the ink volume is less than a predetermined volume; in fig. 2 - the same as when the volume of paint
exceeds the specified volume; on fig.Z the same, axonometrics; FIG. 4 is the same, the use case of the microswitch; in fig. 5 and 6 - various positions of the pivot arm
in version with load; in fig. 7 and 8. A device for adjusting the amount of ink in a printing apparatus with a printing form in the form of a closed ribbon.
0 A device for controlling the amount of paint in a paint machine. printing machine contains a means
1dl paint supply in the wedge-shaped space formed by the surface of the paint-roller 2 and the clamping element 3, which controls the thickness of the layer 4 of paint on the paint-roller 2, mounted on an axis 5 parallel to the axis of rotation b
0 roller 2, pivoting lever 7 and microswitch 8 placed on the path of its movement, connected with means -1 for supplying paint to the wedge-shaped space.
c The end 9 of the swivel lever 7 is placed in formed by rollers.
2 and 3 wedge-shaped space in the zone of location of the volume 10. paint.
On the interacting with the microswitch 8. On the shoulder of the lever 7. the load is strengthened 11.
The lever 7 can be 2-shaped and strengthened by means of brackets 12 (Fig. 3).
The device for adjusting the amount of ink 5 works as follows.
When the screen printing apparatus operates, the screen printing plate 13 is reinforced to the surface. 0 perforated cylinder 14, in
the cavity of which is placed colorful device.
Due to the rotation of the cylinder 14 and the roller 2 interacting with its inner 5 surface, the paint 2 is carried away by the surface of the roller 2 and passing through the gap formed by the rollers 2 and 3, lies 0, 4 on the surface of the roller 2 for distance. her transfer to the print form 1me 13.
Due to the rotation of the rollers 2 and 3, the paint in the volume of 10 all wears is circulating
5 is closed and its stroke is determined by the rotation of the lever 7, the end 9 of which, as the volume of paint 10 decreases in the wedge-shaped space between rollers 2 and 3, moves in the direction-. gap between rollers 2 and 3.. As a result, the second end of the lever 7. acts on the microswitch-. control b
5 by means 1 for supplying paint which
The swarm supplies paints to the wedge-shaped space between rollers 2 and 3. As the ink arrives, the ink volume 10 begins to increase in such a way that it comes in contact with the end 9 of the lever 7 and envelops it. Due to the circulation of paint in vol. last 10, impact on The 9 of the lever 1 tends to enter it, as a result of which the lever 7 begins to rotate in the opposite direction and moves away from the microswitch 8, giving the command to stop. paint supply means 1.
Thus, any changes to the Ink Volume 10 cause the lever 7 that controls the control through the microswitch 8 to move the ink supply 1,
Due to the fact that there is some delay between the moments of the actual termination and renewal of the supply, paint into the wedge-shaped space, the microswitch 8 on and off, and also because the volume 10 of paint at the moment of leaving the end 9 of the lever 7. less than the ink volume 10 at the moment when the end 9 of the lever 7 is still located in the volume, a corresponding hysteresis is provided in the on-off regulation of the volume 10 of the deposited ink, and the size, the ink volume 10 is maintained within certain j boundaries.
FIG. 4 shows an embodiment when the lever 7 was in contact with the microswitch 8 for a predetermined volume of ink 10, which is turned on if contact is made. 14. If it is zke. switching on the microswitch 8 takes place on pin 14, then in the electrical circuit to control the pump of the ink supply means 1, the reverse circuit: conversion is required (inverting circuit It is also necessary that the lever be relatively light, then the end
9 does not concern paint volume 10 and
does not prevent the return of pin 14 to its original position.
FIG. 5 and 6, the end 9 of the lever 7 is provided with a weight 15 and adapted to come into contact with a volume of 10 paint, not penetrating deep into it, regardless of size, i.e. designed as a float. With increasing volume
The 10 paint lever 7 with the load 15 rotates clockwise and operates on the breaker switch 8, which turns off the paint supply by means I.

. In this embodiment, the lever 7 responds only to a change in the volume 10 of the ink and does not react to the circulation of the ink in the volume 10.
The proposed device can be used not only in stencil printing machines, but in other machines, for example, offset or letterpress.
The invention makes it possible to increase the reliability of a device for controlling the amount of ink in an inking apparatus of a printing machine.
