Definitions

  • the invention is based on a device for removing viscous or pasty material, such as sealing material or adhesive, from a container according to the preamble of the first claim.
  • the material 2 is displaced under the pressure of the follower plate 3 through the outlet opening 31 from the container 1.
  • DE-A-37 19 906 discloses a provided with a metering device and rigid outer walls detergent container of circular or square cross-section, which is equipped on one side with a movable, tight-closing follower plate. Due to its weight, the follower plate exerts pressure on the surface of the paste stored in the container and causes the detergent paste via a delivery pipe, possibly a feed pump, can be removed. As the amount of paste decreases, the follower plate slowly follows the paste level down.
  • the device of [2] is only suitable for pastes whose viscosity is relatively low, in particular at about 75,000 mPa ⁇ s to 90,000 mPa ⁇ s, so that pastes with higher viscosities of 150,000 mPa • s up to 250'000 mPa • s are difficult or impossible to remove.
  • the removal of the material 2 is therefore often carried out by means of a powerful feed pump 4 through an outlet opening 31 in the follower plate 1, as shown in Figure 1 in a schematic representation of the removal device.
  • the feed pump 4 which is provided for example with a delivery piston or with a screw conveyor, is suitable for sucking the material, so that the follower plate 3, with material of medium viscosity, does not have to be introduced into the container 1 with increased pressure.
  • a removal device of this type will be described with reference to FIG.
  • the delivery pump 4 has a delivery tube 41 with a conveying screw or spiral 42 held therein, which is connected via a drive shaft 43 to a drive motor 44, for example a three-phase motor.
  • the delivery pipe 41 which is held in the outlet opening 31 of the follower plate 3, has a material outlet 411, from which the conveyed material 2 emerge and can be supplied to an application.
  • the controlled by an electronic control unit 6 motor 44 of the feed pump 4 is held by a lifting stand 5 and vertically movable so that the coaxial with the body axis of the container 1 and perpendicular to the follower plate 3 aligned conveyor tube 41 is inserted with this in the container 1 and after the complete removal of the material 2 by means of the lifting stand 5 is retractable.
  • the lifting stand 5 has a base plate 51 which forms a base frame together with two pneumatic cylinders 52 and a static traverse 53. From the pneumatic cylinders 52 pistons 521 are extendable, which are connected to each other via a mobile Traverse 54, on which the motor 44 of the feed pump 4 is mounted.
  • the feed pump 4 is driven with the follower plate 3 by the lifting stand 5 upwards.
  • the container 1 is now placed under the feed pump 4 and the follower plate 3, aligned coaxially with these and fixed on the base plate 51.
  • the feed pump 4 with the follower plate 3 is then lowered by controlling the pneumatic cylinder 52 against the container 1 until the follower plate 3 rests on the material 2 within the container 1.
  • By means of a provided on the follower plate 3 bleed valve 34 the container 1 is vented, so that the air between the follower plate 3 and material surface can escape.
  • the emptying is now started by means of the control unit 6.
  • the feed pump 4 and the follower plate 3 sink in the container 1 during the conveyance of material 2 down, without any additional pressure on the follower plate 3 must be exercised if the material 2 has a relatively low viscosity. Due to the inherent weight of the follower plate 3 and the negative pressure, which arises during the removal of the material 2, the follower plate 3 is automatically pressed against the material 2 and displaces this against the centrally located on the follower plate 3 outlet opening 31, and the inlet opening of the conveyor tube 41st at which the negative pressure is generated. In addition to generating the possibly required form the follower plate 3 also serves to strip the container in which the material 2 is packaged.
  • the feed pump 4 is automatically shut off, for example, by means of a level switch of the control unit 6. Subsequently, in turn, the vent valve 34 is actuated and the follower plate 3 is raised by the lifting stand 5.
  • the invention is therefore based on the object to provide an improved device of the type mentioned.
  • a provided with a follower plate removal device is provided by means of the highly viscous material, such as sealing material and adhesive, in particular while avoiding disturbing temperature or structural changes can be removed with little effort from a container.
  • the removal device should be manufactured inexpensively, easy to use and can be maintained with little effort.
  • the device which serves for the removal of viscous or pasty material from a container, has a displaceably mounted by means of a lifting stand follower plate, in which an outlet opening is provided through which the material can escape when the follower plate is lowered into the container.
  • the follower plate on the side facing the material at least one static or dynamic guide member which is rotatably supported or supported relative to the material and shaped so that it can engage in the material and displace this in a relative movement against the outlet opening of the follower plate.
  • the relative movement between the guide member and the material, or the container which can be effected by a movement of the guide member or by a rotation of the container, causes a transfer of material to the exit plate of the follower plate, from which it can escape by the applied pressure ,
  • a feed pump can be provided which detects the material in the region of the outlet opening and carries it away.
  • the material is neither heated nor stirred mechanically.
  • the material is fed neither mechanical nor thermal energy to reduce its viscosity.
  • the material without changing its properties, conveyed to the outlet opening of the follower plate out.
  • the application of the material can therefore be carried out without disturbing influences and corresponding changes in the properties of the material to be considered.
  • the removal device according to the invention also requires no elaborately designed device parts.
  • the use of a heating system with appropriate wiring is also avoided, as is the use of a stirring propeller that must be immersed in the high viscosity material and rotated therein and cleaned after use.
  • the sampling device can extremely extremely viscous material detected in the container, promoted with little effort to the outlet and removed there.
  • the removal device it is even possible to remove material in which, due to the high viscosity, a stirring propeller can hardly be used anymore.
  • the guide element engages only as far in the material as it is necessary for the promotion of the material towards the outlet opening of the follower plate. Mechanical processing of the material to reduce the viscosity can be avoided. There are therefore no high forces and little energy needed, which also offers significant advantages in terms of reduced design effort.
  • the guide plate with one or more guide elements can be manufactured in comparison to conventional follower plates practically without additional expenditure as a casting. Furthermore, in the device according to the invention, only a minimal amount of maintenance results, since during the cleaning of the follower plate the guide elements can also be cleaned at the same time. Further, it should be noted that the guide elements held by the follower plate are subjected to a reduced load compared with a mixing propeller which must be completely immersed in highly viscous material and therefore will not show signs of wear or defects even with simple dimensioning and longer service life.
  • the guide element is preferably connected in one piece to the follower plate spiral track or a segment thereof, the first end of the outlet opening is closer than the second end piece.
  • the follower plate consists of a preferably plate-shaped first part and a rotatably mounted by means of the first part preferably plate-shaped second part on which the at least one guide element is provided.

  • the guiding and conveying elements and the material can be moved in different ways relative to each other, wherein a plurality of motors or only one motor with corresponding coupling means and gearboxes can be used.
  • the follower plate or the second part of the follower plate provided with the at least one guide element can be rotated by means of a motor or the container can be rotatably mounted and rotated relative to the follower plate by means of a motor.
  • the follower plate may have static and / or dynamic guiding and conveying elements.
  • the follower plate can only have dynamic conveying elements and a drive which not only the Conveyor elements, but also drives the follower plate, so that it is rotated while the conveying elements convey the material to the outlet opening.

  • a feed pump is provided with a delivery pipe, which with the Outlet opening is connected in the follower plate and in which a motor-driven conveyor part, in particular a screw conveyor, is provided, is detected by the material, optionally within the container, and conveyed away. If no delivery pump is provided, an increased pressure can be exerted on the follower plate by means of the lifting stand in order to displace the material from the container. Both measures, namely the use of a feed pump and the exercise of pressure by means of the lifting stand or further pressure generator, can also be used in combination.
