Definitions

  • the invention relates to a device for conveying viscous material according to the preamble of claim 1 and a method for conveying viscous material in which such a device is used.
  • the follower plate when the follower plate is lowered, it wipes off any material adhering to the inner surface of the drum wall. If the barrel is empty, it must be exchanged for a new, full barrel. For this purpose, the follower plate must be moved up out of the barrel. In order to be able to move the follower plate upwards in the barrel, the inside of the barrel must be ventilated, otherwise a vacuum would arise in the barrel, which would prevent the follower plate from moving out. This is achieved in previously known devices in that compressed air is introduced into the drum through a ventilation opening in the follower plate. Since the follower plate has a large area, an overpressure in the drum causes a large force on the follower plate. Controlling the upward movement of the follower plate therefore requires some effort.
  • the follower plate has a wiper ring, the size of which can be varied by introducing pressurized gas, so that the follower plate is suitable for containers of different diameters.
  • the follower plate shown there is designed as a heatable melting plate, which serves to melt the material in the container for the purpose of liquefying it.
  • the invention is based on the idea of varying the sealing effect of the wiper ring in a targeted manner in order, on the one hand, to achieve a good sealing effect when the barrel or the container is at least partially filled with viscous material, and to prevent air from entering the container , and on the other hand to cancel the sealing effect and thus also the frictional force between the follower plate and the container in whole or in part when the follower plate is inserted into the container or removed from the empty container.
  • a contact portion of the wiper ring that projects radially outwards and is intended to rest against the inner surface of the container wall can be acted upon with a variable contact force for pressing against the inner surface.
  • the contact pressure is variable in the sense that it can assume at least two different values, with one value achieving a sealing effect and the other value achieving no or only a slight sealing effect.
  • the contact force can be changed discretely or continuously between these extreme values.
  • the lifting device expediently has at least one guide rod that is fixedly connected to the crossbeam and is linearly movable in a guide in the vertical direction, as well as a drive unit for raising and lowering the crossbeam.
  • the drive unit can act on the traverse, on the guide rod or the guide rods, or on a component connecting the traverse to the guide rod or the guide rods.
  • each guide rod is linearly movable in a tubular guide and at or near a lower end has a first guide element resting against an inner surface of the guide, while the guide has a stationary guide element resting against an outer surface of the guide rod at or near an upper end having second guide element.
  • the respective guide rod is guided particularly precisely by means of the two guide elements, which are arranged at the greatest possible distance from one another.
  • a spindle drive for raising and lowering the crossbeam is provided, which is preferably driven by an electric motor.
  • a transport device for transporting the container in a direction transverse to the longitudinal extension of the traverse.
  • This transport device is used in particular when the lifting device is set up on a building wall and the traverse extends away from the building wall in its longitudinal extension extending from the lifting device to the free end. Then it is possible that the transport device transports the container parallel to the extension of the building wall to the follower plate and the emptied container from the follower plate transported away.
  • the transport device has a roller conveyor on which the container is placed.
  • the conveying device has a housing which surrounds the container and the follower plate and has at least one door.
  • the housing increases the safety of the operating personnel when moving the follower plate into the container.
  • the conveying device has a transport device for transporting the container in the direction transverse to the longitudinal extension of the traverse, it is advantageous if the housing has two doors through the container into and out of the housing by means of the transport device is transportable. The doors are then expediently arranged on opposite sides of the housing.
  • the conveyor device according to the invention with a control device with which the container is automatically positioned under the follower plate by means of the transport device, with which the follower plate is automatically inserted into the container, with which the follower plate is automatically removed from the container after it has been emptied is removed and with which the emptied container is automatically transported away by means of the transport device.
  • the contact part can be withdrawn from the inside of the container wall by reducing the contact pressure.
  • the contact pressure is then zero.
  • the follower plate can then be removed from the container, with the wiper ring ideally not touching the container wall.
  • the pressure force can be varied in different ways.
  • the wiper ring is hollow and at least one has partially encircling, with a pressure medium fillable cavity enclosing outer wall.
  • the outer wall is expediently thicker in the area of the system part than in its other areas.
  • a device is advantageously provided with which the pressure medium, for example a liquid such as oil, but preferably gas and in particular air, can be introduced into the cavity or drained from it. If pressure is applied to the cavity, the wiper ring expands and the contact pressure with which the contact part is pressed against the container wall is increased. If the outer wall is thicker in the area of the contact part, there is more material available so that the sealing effect is improved.
  • the contact part can be moved between a sealing position and a release position by applying two predetermined different pressures to the cavity by means of, for example, a ventilation device.
  • a sealing position it lies against the inner surface of the container wall in a sealing manner, while in the release position the sealing effect with the inner surface of the container wall is canceled.
  • the follower plate can have a wiper ring.
  • at least one further wiper ring can advantageously be provided, which is structurally identical to the wiper ring and is arranged at a distance parallel to it.
  • feed pumps have a feed cylinder and a feed piston that can move back and forth in the feed cylinder. It was found at the applicant that the speed of the delivery piston during the delivery process can vary depending on the material consistency. The applicant has found out through experiments that the speed of the delivery piston during the delivery stroke is constant at least within a tolerance range while the material consistency remains constant. If the conveyed material contains air bubbles, this leads to a significant change in the speed of the delivery piston during the delivery stroke.
  • the device 10 shown schematically in the drawing is used to convey viscous material such as adhesive, sealant or insulating material from a barrel-like container 12.
  • the conveying device 10 is shown in FIG Figs. 1 to 3 not in all Details are shown, but reduced to the essential components for understanding the sealing of the container 12.
  • the container 12 essentially has a cylindrical shape with a container base 14 and a container wall 18 extending upwards from the container base 14 to a container top side 16 and encircling the periphery.
  • the container 12 is open to the container top side 16.
  • the conveying device 10 has a follower plate 20 which is introduced into the container 12 for conveying the material and rests there on the material surface.
  • the follower plate 20 can by means of an in Figs. 1 to 3 lifting device not shown are moved up and down. It has a central dome 22 which extends upwards from an underside 24 lying on the material and opens into a material outlet 26. The material is removed from the material outlet 26 by means of a likewise in Figs. 1 to 3 Not shown delivery pump promoted via a delivery line to the place of use.
  • the follower plate 20 has a circumferential wiper ring 28 made of elastically stretchable material, in the present case of rubber, which is tubular with an outer wall 32 enclosing an annular cavity 30.
  • the outer wall 32 is radially outwardly pointing and protruding outward Area is thickened to form a contact part 34 which is intended for sealing contact with an inner surface 36 of the container wall 18. If a pressure medium is introduced into the cavity 30, for example compressed air is applied to it by means of a ventilation device (not shown), the wiper ring 28 expands and the contact part 34 moves radially outward.
  • the system part is moved into a sealing position in which it, as in FIG Figures 2a, 2b shown, is pressed by the force exerted by the compressed air in the cavity 30 against the inner surface 36 and seals the container interior 38 located under the follower plate 20 from the environment.
  • the follower plate 20 is in the in Fig. 2a position shown, in which its bottom 24 rests on the surface of the material in the filled container 12.
  • the contact part 34 is in its sealing position, so that the wiper ring 28 seals the container interior 38 from the environment. If material is conveyed out of the container 12, the material level drops and the follower plate 20 is moved downwards following the material level by means of the lifting device in the container 12, the contact part 34 sliding over the inner surface 36, overcoming a frictional force, and wiping off any material adhering to it .
  • the follower plate 20 When the container is completely empty, the follower plate 20 is on the container bottom 14, as in FIG Figure 2b shown, with a thin film of material between the follower plate 20 and the container bottom 14 possibly also being located.
  • compressed air is introduced into the dome 22, so that the follower plate 20 is lifted from the container bottom 14.
  • the force pressing the contact part 34 against the inner surface 36 is removed by releasing compressed air from the cavity 30, so that the contact part 34 withdraws from the inner surface 36.
  • the contact part 34 is then in a release position in which the sealing effect between the container interior 38 and the environment is canceled.
  • the follower plate 20 is then lifted out of the container 12 until it is back in the position shown in FIG Fig. 1 position shown.
  • the empty container 12 can then be replaced by a new, full container and the conveying process can begin again.
  • feed pump 40 At the material outlet 26 of the follower plate 20 is a fixedly connected to the follower plate 20 feed pump 40, which is used to convey material from the container 12 via the material outlet 26 into a feed line 42 leading to a processing station.
  • the feed pump 40 has a feed cylinder 44 fixedly mounted on the follower plate 20 and a feed piston, not shown in the drawing, which can move back and forth in the feed cylinder 44 and whose linear movement in the feed cylinder 44 material through the material outlet 26 sucks into the delivery cylinder 44 and pushes the material out of the delivery cylinder 44 into the delivery line 42.
  • a lifting device 50 is provided in the conveyor device 10 according to the invention, on which a horizontally extending cross member 52 in the form of a metal plate is provided its first end 54 is mounted, while its second end 56 is free.
  • Two holding rods 58, which carry the follower plate 20, run vertically downward from the traverse 52.
  • the lifting device 50 has a spindle drive, which is not shown in detail and is driven by means of an electric motor, for lifting and lowering the cross member 52.
  • the conveying device 10 also has a transport device 80 which has a roller conveyor 82 with which the container 12 can be transported in a direction perpendicular to the longitudinal extent of the cross member 52. In this way, empty containers 12 can be transported away from the follower plate 20 and full containers 12 can be transported under the follower plate 20.
  • a housing 84 is also provided, which surrounds the container 12 and the follower plate 20 during the introduction of the follower plate 20 into the container 12 and during the conveying of the material.
  • the housing 84 has two transparent sliding doors 86, 88 arranged one above the other, each surrounding an interior space, which surround the container 12, the follower plate 20 and the feed pump 40 during operation in order to minimize the risk of injury to the operating personnel.
  • the upper sliding door 86 can be displaced downwards, while the lower sliding door 88 can be displaced upwards in order to enable a container to be changed.
  • a control device is provided with which a filled container 12 is automatically positioned under the follower plate 20 by means of feed on the roller conveyor 82, with which the follower plate 20 is automatically inserted into the container 12, with which the follower plate 20 after the container 12 has been emptied is automatically removed from this and with the emptied container 12 by means of the transport device 80 is automatically removed.
  • a sensor 98 detects the correct positioning of the container 12 under the follower plate 20.

  • the displacement measuring device 90 also has a control unit, not shown in detail, which controls the conveyance of the viscous material as a function of the measured speed of the conveying piston.
  • the control unit detects when the measured speed of the delivery piston is outside a tolerance range around a specified target speed, which indicates that the consistency of the material being conveyed has changed to such an extent that its suitability is in question. In this case, the control unit switches a valve 100 so that the conveyed material is not conveyed to the processing station, but into a waste line 102 branching off from the conveying line 42 and leading to a waste container 104. If the control unit detects that the speed of the delivery piston is again within the tolerance range, it switches the valve 100 again, and the viscous material is again delivered to the processing station via the delivery line 42.
  • the measuring device 90 is intended in particular to prevent material interspersed with air bubbles from being conveyed.
  • the follower plate 20 can be used in particular when the follower plate 20 has been inserted into a full container 12 in order to convey material into the waste container 104 in an automatic process until it no longer has any air bubbles. However, it can also be used during the conveying process and detect the air bubbles present in the material and convey the material mixed with air bubbles into the waste container 104 instead of to the processing station.
  • Fig. 5 For the sake of clarity, the illustration of the measuring device 90, the valve 100, the waste line 102 and the waste container 104 has been omitted.
