Abstract
A liquid tank 1 for damping units of printing presses consists of a tubular body 2 extending over the width of a damping unit and sealed at its ends 3 and 4 by covers 5 and 6. The base frame 2 is provided with filling and outlet connections 7 and 8 arranged on its periphery and on opposite sides, the outlet connection having a shut-off valve 9 extending into the damping fountain. The filling connection 7 may be made airtight by means of a screw plug 12. Preferably, the body 2 is made of transparent material, and is supported in rails 15 on the side-frames of the press. <IMAGE>
Description
SPECIFICATION
Hermetically Sealable Spare Liquid Tank
This invention relates to a spare liquid tank for damping units, in which a specific liquid level can be adjusted in the damping fountain by means of a pipe between the spare liquid tank and a damping fountain, the spare liquid tank being arranged within the machine contours.
Spare liquid tanks of this type are already known and can therefore be found on virtually all printing presses having a damping fountain. The purpose of these spare liquid tanks is to ensure that the water level in the damping fountain of a damping unit is kept to the required level over a long period. The volume of the spare liquid tank should preferably be sufficient to meet the liquid requirement of a working day. As it is well-known that little space is available in printing presses, most spare liquid tanks are often arranged outside the printing press. This requires a special holder to secure the spare liquid tank to the printing press.
As the spare liquid tank is then one of the "visible" parts of the printing press, a spare liquid tank of attractive design must generally be used.
These spare liquid tanks are also correspondingly expensive.
According to the present invention there is provided an hermetically sealable spare liquid tank for a damping unit, in which a specific liquid level can be adjusted in the damping fountain by means of a pipe between the spare liquid tank and a damping fountain, the spare liquid tank being arranged within the machine contours, wherein the spare liquid tank consists of a tubular frame extending across the width of the damping unit and sealed at its ends by covers, the frame has opposite filling and outlet connections on its periphery and the outlet connection is provided with a shutoff valve and extends into a damping fountain, the filling connection having a thread on to which a screw plug can be screwed airtight.
Such a spare liquid tank can be manufactured inexpensively, and has the advantage that the space requirement inside the printing press can be no greater than that of a damping unit roller. A pipe may be used for the tubular frame, which further reduces the cost of production. PVC pipes as also provided for air lines in printing presses, for example, can be used. The pipe may be of transparent material, enabling the liquid level to be easily seen.
The invention is explained in more detail below with reference to a specific exemplary embodiment shown diagrammatically in the accompanying drawings, in which:
Figure 1 shows a section of part of a printing press including a damping unit,
Figure 2 is a longitudinal section through a spare liquid tank, and
Figure 3 is a further longitudinal section on an enlarged scale.
The spare liquid tank 1 consists of a tubular frame 2 sealed by covers 5 and 6 at its ends 3 and 4. The covers 5 and 6 can be welded or glued to the frame 2. A filling connection 7 and an outlet connection 8 are arranged opposite each other on the periphery of the frame 2. A shutoff valve 9, which extends into the damping fountain 10 of the damping unit, is mounted on the outlet connection 8. The filling connection 7 has a thread 11, on to which a screw plug 12 can be screwed airtight.
The spare liquid tank 1 can be secured, for example, by rails 13 on its ends 3 and 4, with the aid of which the spare liquid tank 1 can be pushed into a pair of guide rails 1 5 which are fixed to the press frame and locked, in position. In the embodiment illustrated, locking is by means of clamping screws 1 6.
Claims
1. An hermetically sealable spare liquid tank for a damping unit, in which a specific liquid level can be adjusted in the damping fountain by means of a pipe between the spare liquid tank and a damping fountain, the spare liquid tank being arranged within the machine contours, wherein the spare liquid tank consists of a tubular frame extending across the width of the damping unit and sealed at its ends by covers, the frame has opposite filling and outlet connections on its periphery and the outlet connection is provided with a shut-off valve and extends into a damping fountain, the filling connection having a thread on to which a screw plug can be screwed airtight.
2. A spare liquid tank according to claim 1 and including guide rails arranged on its ends for securing the spare liquid tank in a printing press.
3. A spare liquid tank according to claim 1 or 2 wherein the tubular frame is formed of transparent material.
