Definitions

  • the invention relates to a liquid supply device for supply of machines with a liquid from a container according to the preamble of claim 1.
  • Liquids such as especially glue, paint and varnish as well as organic Detergents must be kept liquid-tight so that they do not can dry out and react with oxygen, their volatile components cannot evaporate and no bacterial cultures develop in them can.
  • Such liquids are usually made in containers Plastic or metal kept. If the liquid from such Container is pumped out with a pressure pump, air is in the container pressed. This allows the liquid to react with the oxygen in the air volatile components can escape from the liquid, and the Conveying speed is limited because the containers have high air pressures Do not stand the pressure pump unless there are containers made of very thick Plastic material or metal used. The use of containers with thick plastic walls or metal is expensive to manufacture and very expensive expensive to dispose of (sometimes as hazardous waste) or in the recycling process and the containers are heavy. Due to the limited pressure resistance the container is also the delivery pressure of the pressure pump and thus the Fluid delivery speed limited. This limitation has one Limitation of the production speed of the liquid supplied Machine result.
  • a preferred application of the invention relates to glue machines which a container, e.g. Canister, glue fed for application to finished paper to glue sheets of paper or paper webs together.
  • a container e.g. Canister
  • Paper can also be sheets in the form of sheets (sheets) or endless webs made of plastic, metal, cork or another material.
  • the machine is a coating machine for coating a substrate with a Coating material.
  • the carrier material is preferably paper in the form of Sheets of paper or webs of paper. Sheets can also be in the form of sheets or Sheets of plastic, metal, cork or other material coated become.
  • the coating material is preferably paint or lacquer.
  • Another preferred area of application of the invention is machinery or Devices for moistening finished paper to a desired one Reach moisture content and at a predetermined value or Keep value range, e.g. with so-called softening liquid, which is water can be to make paper easier to fold so that it is not in folders tears.
  • Softening liquid is especially a commercially available folding aid concentrate, which is a mixture of water and additives e.g. Vinegar and / or dish soap
  • Offset printing machines use so-called Fountain solution to form ink-repellent areas on one Printing plate cylinder.
  • the fountain solution consists of water, alcohol or Alcohol substitute and so-called additives.
  • These liquid additives can according to the invention from an airtight storage container to one Fountain solution preparation tub of the printing press can be conveyed without that the additive comes into contact with air. This prevents organic additive is infested with bacteria or fungi or with Oxygen can react.
  • the liquid is pumped from the Container pushed out. This has the disadvantage that if the delivery pressure is too high there is a risk that the container will burst. There is also a risk that the Compressed air from the pressure pump reacts chemically with the liquid or is in the Liquid bacteria or fungi can develop. It is also known Suck the liquid out of a dimensionally stable canister using suction pumps.
  • the object of the invention is to achieve a possibility of through which arbitrarily large quantities of liquid are conveyed out of the container material costs, weight and costs for the container and its disposal or recycling can be reduced can, as well as contact of the liquid in the container with air or other Gases can be avoided.
  • the walls of the container are designed in such a way that the suction force of the Suction pump, which is required to convey the liquid, bendable and can be moved against each other without the suction force of the suction pump needs to be much higher than for sucking the liquid out of one open container.
  • the container walls can be dimensionally unstable, but none or have such a low bending stiffness that they are slightly flexible and could not stand upright on their own without bending, kinking or in fold up.
  • the walls of the Container is dimensionally stable, but already due to a low suction power Suction pump plastically deformable. This means that the container walls after the plastic deformation when the deformation forces decrease their deformed Maintain shape.
  • glue machines Coating machines and printing machines.
  • glue machines and Coating machines apply the liquid to a carrier in the form of finished paper or foil applied, the foil made of metal, plastic or Cork or other material can exist.
  • the liquid is a Dampening liquid, e.g. Water, for moistening finished paper, with it it can then be folded or folded more easily in a folder, without tearing the paper.
  • a Dampening liquid e.g. Water
  • the invention can be used for offset printing presses to make liquid To feed additives from a collapsible container to a mixing container, in which the additive with water and alcohol or alcohol substitute is mixed to form dampening water, which one Printing plate cylinder is supplied to form ink-repellent areas.
  • the fountain solution can also be fed to cylinders or rollers of the printing press such as paper guide rollers and chill rollers to prevent contamination, e.g. also to prevent or remove ink deposits.
  • FIG. 1 shows a container which can be collapsed by the suction force of a suction pump 20 4 in an outer container 6 which supports it laterally and made of non-collapsible stiff material.
  • the collapsible container 4 has a neck 8 with a thread on which by means of a threaded sleeve 10 the end 12 of a fluid line 14 is airtight connectable, the other end 16 to the suction side 18 one Suction pump 20 can be connected.
  • the pressure side 22 of the suction pump 20 is connected via a further fluid line 24 connected to a machine 26 which dispenses liquid from the suction pump 20 the container 4 can be fed.
  • the container 4 is designed to be collapsible in such a way that it passes through the subatmospheric pressure of the suction pump 20 is easily collapsible and corresponding to the amount of liquid drawn from it and collapses the suction power of the suction pump 20 offers only very little resistance.
  • the walls of the container 4 can be very dimensionally unstable so that they do not or only have low bending stiffness and do not stand upright on their own without bending, kinking or collapsing.
  • the walls of the container 4 Dimensionally stable, but with extremely little force, which is due to the conveying suction force the suction pump 20 is applied, easily plastically deformable.
  • This easy plastic deformability has the consequence that when the suction power decreases the suction pump 20 the container 4 maintains its deformed shape.
  • the container 4 in one to accommodate dimensionally stable outer container 6, from whose side walls he on old pages is supported.
  • the outer container 6 not only makes it easier Transport of the dimensionally unstable container 4, but also prevents Damage to him.
  • the container 4 consists of flexible plastic or rubber.
  • Such containers are simple and inexpensive to manufacture very thin-walled, e.g. by thin from a foil-like Plastic tubing hose sections cut off at both ends be welded shut. During the welding process, at the same time a hose end a line connection are formed, which in the Figures 1, 2 and 3 in the form of the neck 8 is shown symbolically.
  • the end 12 of the suction fluid line 14 to be connected to the container 4 can be designed as a puncture tube 28 or be provided with such a puncture tube 28 for piercing a container closure 30 on the neck 8.
  • the Container closure 30 can be a film welded onto the neck 8 or through the container 4 itself be formed.
  • the puncture tube 28 can without the Threaded sleeve 10 are used or be designed so that they Screw the threaded sleeve 10 to the neck 8 through the container closure 30 is inserted automatically.
  • the suction fluid line 14 is a lancing element in the form of a knife-like or have needle-like tip, which has no liquid passage opening.
  • the end 12 the suction fluid line 14 in the neck 8 or at least through the threaded sleeve 10 protrude or be fluidly connected thereto.
  • the container 4 need not have a neck 8, but rather that through the neck 8 formed line connection of the container 4 can also by a flat or be formed differently shaped container wall of the container 4, which the Cover wall, a bottom wall or a side wall of the container 4 can be.
  • the machine 26 can be of any of the types mentioned.
  • Figure 3 shows an example of a glue machine 26, in which glue from the Container 4 on one or both tracks 32 and 34, e.g. Paper webs, is applied, which are glued together by the glue.
  • glue machines and also the other types of machines are in practice are known and are therefore not described in detail.
  • the container 4 is designed such that it corresponds approximately to the continuously sucked from him by the suction pump 20 amount of liquid collapsed.
  • the collapse of the container 4 follows substantially continuously Fluid withdrawal.
  • the collapsible container 4 is preferably in the form of a flexible bag.
  • the capacity of the collapsible container 4 is at least 1 liter (1 cubic decimeter).
