Definitions

  • the invention relates to a container follower device for a material storage container and a conveying device with the container follower device for conveying material from the material storage container.
  • the container follower device can be part of a conveying device, the conveying device being used to convey viscous material from the container.
  • the conveying device reliably transfers various medium- to high-viscosity materials, such as sealants, adhesives, or silicone rubber, from containers like buckets or drums to different processing systems.
  • the viscous material is typically supplied by the material supplier in containers with a capacity of 20 to 1000 liters.

  • the channel serves to direct the air to the outlet opening.
  • the channel can be designed in a ring shape around the material extraction opening.
  • the channel can, for example, have a circular, rectangular, or polygonal shape.
  • the separating layer is arranged between the material extraction opening and the mouth of the channel.
  • the porous layer is arranged in such a way that it is not in contact with the follower plate, at least in the area of the separating layer.
  • the porous layer preferably has an outer diameter that is selected such that the porous layer centers itself within the material storage container.
  • a conveying device for transporting material from a material storage container which includes the container follower device described above. It also features a material conveyor designed to convey the material through the container follower device.

  • the porous layer is placed in the material storage container.
  • the follower plate is lowered onto the porous layer.
  • the gas remaining in the material storage container is discharged from the material storage container via the outlet opening.
  • the subsequent plate is lifted out of the material storage container without the porous layer.
  • Figure 1 shows a first possible embodiment of a container follower device 1 for a material storage container 2 in cross-section.
  • the container follower device 1 is generally part of a conveying device 20 with which viscous material 3 can be conveyed out of the material storage container 2.
  • a conveying device 20 is shown in the Figures 8 to 17 shown.
  • the conveying device 20 can reliably convey various medium- to high-viscosity materials, such as sealants, adhesives, silicone rubber or greases, from the material storage container 2 to various processing systems.
  • various medium- to high-viscosity materials such as sealants, adhesives, silicone rubber or greases
  • the conveying device 20 comprises a material conveyor 11.
  • the material conveyor 11 can, for example, be a pump.
  • the pump 11 comprises a drive 14, an associated drive rod 18, and a pump body 15.
  • the pump 11 is driven via the drive 14 and the drive rod 18.
  • the drive 14 is configured to cause the drive rod 18 with piston 19 to perform a stroke movement, which is transmitted to the piston 19 of the pump 11.
  • the pump 11 can also be a piston pump without a piston instead of a piston pump.
  • the scoop piston has the advantage with highly viscous materials that the viscous material is scooped directly to the material extraction opening 8.
  • the material extraction opening 8 is also referred to as the pump inlet in the following. This improves the pump's suction performance.
  • the pump 11 is designed as a gear pump, screw pump, or progressive cavity pump
  • the drive is designed such that it sets the drive rod 18 into a rotational movement, which is transmitted to the gear pump, screw pump, or progressive cavity pump, respectively.
  • Pump 11 is designed as a piston pump.
  • Figure 1 Figure 11 shows the basic construction of such a piston pump.
  • a follower plate 4 which can be inserted into the material reservoir 2 containing the material 3 to be pumped.
  • the material reservoir 2 will henceforth be referred to simply as the reservoir or container.
  • the follower plate 4 is preferably equipped with an annular seal 5 so that the follower plate 4 can seal against the inside 2.1 of the container wall 2.4.
  • the seal 5 can be, for example, an O-ring or a sealing lip. Among other things, it ensures that no material 3 escapes between the follower plate 4 and the container wall 2.4.
  • the seal 5 also enables the effective creation of a vacuum inside the container 2.2.
  • One possible embodiment of the seal 5 is shown in the Figures 3 and 4 shown. In this embodiment, the seal 5 is ring-shaped.
  • the outer diameter of the seal 5 and the inner diameter of the container 2 are matched to each other.
  • the outer diameter of the seal 5 can, for example, be 288 mm. Generally, the seal 5 should be larger than the inner diameter of the container 2.
  • a suitable container 2 has a diameter of 292 mm if the seal is designed as an O-ring. If the seal 5 is designed as a sealing lip, it can seal a gap of, for example, 0 to 20 mm.
  • the invention is also suitable for a 200-liter material storage container (inner diameter approximately 570 mm). Naturally, the invention can also be used for even larger material storage containers.
  • the seal 5 can be arranged between the follower plate 4 and the separating plate 6.
  • the follower plate 4 can also have a groove 4.2 in which the seal 5 is arranged.
  • the groove 4.2 is indicated by a dashed line.
  • the follower plate 4 has a pressure-effective surface 4.2, which can be at least partially inclined. This allows the pressure on the material 3 to be conveyed to be partially increased, ensuring that the material 3 flows more strongly towards the material discharge opening 8.
  • the piston pump has a piston for this purpose, with a piston disc 19 located at its lower end. To remove the material 3 from the container 2 To convey material, the drive rod 18 is moved downwards, causing the plunger 19 to dip into the material 3 and pick up material. During the upward movement of the drive rod 18, the plunger 19 carries the material 3 through the material discharge opening 8 into the interior of the pump 11.
  • the container follower device 1 is designed so that it can be lowered in the material supply container 2. This allows the level of the container follower device 1 to adjust to the changing material level.
  • the pump 11 can convey the material 3 out of the storage container 2 through the container follower device 1.
  • the container follower device 1 comprises a channel 9 and an outlet opening 13 connected to the channel 9 for venting gas from the material storage container 2.

  • the separating layer 10 can be, for example, a film, a sheet of metal, or a plastic plate.
  • the separating layer 10 can also be a coating, such as a layer of paint. It can also be a silicone layer. If an adhesive layer is present, it can also serve as a separating layer.
  • the separating layer 10 can also be a layer saturated with a liquid.
  • a liquid is used that hardens or cross-links within the layer, resulting in a gas-impermeable separating layer 10.
  • the porous layer 7 has a large number of pores.
  • a pore is defined here as a very small opening in layer 7 that is permeable to gas.
  • the number of pores per unit length in the porous layer 7 is preferably between 5 ppi and 250 ppi (pores per inch).
  • the porous layer 7 can, for example, consist of sintered material.
  • the porous layer 7 can also be produced using a 3D printing process.
  • the porous layer 7 is preferably designed in such a way that it remains permeable to air even during evacuation, i.e. when the air is extracted from the interior of the container 2.2.
  • the inlet-side opening of the channel 9 is preferably at least 10 mm and preferably 20 mm away from the material extraction opening 8.
  • a separating plate 6 can be arranged between the porous layer 7 and the seal 5.
  • the separating plate 6 serves as additional support between the seal 5 and the porous layer 7. It also ensures a more homogeneous force distribution.
  • the separating plate 6 can have air extraction openings 9. Air can be drawn out of the container 2 through the air extraction openings 9. The air flows from below through the porous layer 7, the air extraction openings 9, the through-opening 4.1, and the outlet opening 13 to the outside.

  • the seal 5 preferably has a larger
  • the diameter of the subsequent plate 4 is greater than that of the subsequent plate 4. This has the advantage of increasing the sealing effect, so that, for example, material 3 adhering to the container wall 2.4 is wiped downwards by the seal 5 when the subsequent plate 4 is lowered into the container 2. This reduces material loss.
  • the seal 5 has the same diameter as the subsequent plate 4.
  • the seal 5 is ring-shaped.

  • the separating layer 10 has a smaller diameter than the porous layer 7.
  • the ratio of the diameters between the porous layer 7 and the separating layer 10 shown here is also purely illustrative.
  • the diameter of the separating layer 10 could, for example, be approximately the same as that of the porous layer 7. However, the diameter of the separating layer 10 could also be significantly smaller than, for example, in the diagram.
  • Figure 5 The diameter of the separating layer 10 depends on the size of the container 2 used.
  • the separating layer 10 preferably covers between 10% and 90% of the porous layer 7.
  • the conveying device 20 is, according to the Figures 8 to 17 To illustrate an embodiment.
  • the drive 14 is attached to a motor mount 28.
  • the motor mount 28 is attached to a yoke 21 by means of a first rod 23 and a second rod 25.
  • the two rods 23 and 25 can be designed as tubes and hold and stabilize the two lifting rods 24 and 26.
  • the follower plate 4 is located at the lower end of the two lifting rods 24 and 26.
  • the yoke 21 is supported by two lifting cylinders 31.
  • the lifting cylinders 31, the yoke 21, the rods 23, 24, and the lifting rods 25 and 26 form a pump jack, which serves to raise and lower the drive 14, the pump 11, and the follower plate 4.
  • the lifting cylinders 31 are usually pressurized, which allows the follower plate 4 to automatically follow the material level.
  • the porous layer 7 can be directly or indirectly connected to the subsequent plate 4. In this case, the porous layer 7 moves along with the subsequent plate 7. Alternatively, the porous layer 7 can be not connected to the subsequent plate 4. In this case, the porous layer 7 is simply placed loosely on the material surface. When the subsequent plate 7 is raised, the position of the porous layer 7 does not change. However, when the subsequent plate 7 is lowered, the porous layer 7 is inevitably lowered as well, because the subsequent plate 7 presses down on the porous layer 7 from above, thus carrying it along.
  • the container follower device 1 is first pulled out of the container 2. Then, the container 2 is removed from the conveying device 20. Next, a full container 2 is pushed into the conveying device 20 and positioned under the follower plate 4. The container follower device 1 is located in the Figures 8 and 9 position shown, i.e. above container 2.
  • the pump drive 14, the pump 11, and the container follower device 1 are lowered until the porous layer 7 in the container 2 rests on the material 3 to be conveyed. During this process, air may become trapped between the surface of the material 3, the container wall 2.4, and the porous layer 7. This occurs regardless of whether the porous layer 7 is connected to the follower plate 4 or not.
  • the porous layer 7 can first be placed in the container 2 and then the subsequent plate 4 lowered onto the porous layer 7. In the latter procedure, the porous layer 7 is preferably placed in the container 2 by hand and, if necessary, lowered until it reaches the material 3.
  • the follower plate 4 and the porous layer 7 can be left to rest on the material 3 to be conveyed for a specific period of time in an initial venting phase, allowing the material 2 time to spread out.
  • the duration (resting time) can, for example, be adjusted to the viscosity of the material.
  • the initial venting phase is optional.
  • the venting valve on the vessel follower device 1 is opened, allowing the air located under the porous layer 7 to pass through the porous layer 7 and then escape through the channel 9 and the outlet opening 13.
  • the airflow path is indicated by arrows (see figure).
  • Figure 1 The air is passed through the porous layer 7, which covers the material surface up to the edge of the container. The air can also flow between the separating layer 10 and the separating plate 6. The vent valve is then closed again. This procedure is advantageous, but not strictly necessary.
  • the porous layer 7 can be pressed onto the material 3 with the aid of the follower plate 4.
  • the air can be Additional vacuum can also be extracted via the outlet opening 13.
  • a vacuum generator such as a vacuum suction nozzle or a vacuum pump, can be connected to the outlet opening 13.
  • the conveying mode can be switched on and the material 3 can be conveyed out of container 2 (see Figures 12 and 13 During conveying, the container follower device 1 is continuously lowered into the container 2.
  • the interior of the container 2.2 located beneath the follower plate 4 can be connected to the environment, for example via connection 12 and channel 9. This allows air from the environment to enter the interior of the container 2.2 and prevents a vacuum from forming inside the container 2.2 when the follower plate 4 is withdrawn. This allows the follower plate 4 to be withdrawn from the material storage container 2 with minimal energy expenditure.
  • compressed air is introduced into the material reservoir 2 when the follower plate 4 is withdrawn from the material reservoir 2. This creates overpressure between the follower plate 4 and the material reservoir 2, which assists in the withdrawal of the follower plate 4.
  • the compressed air/pressurized gas can, for example, be blown under the follower plate 4 via channel 9.
  • the compressed air is routed into the container 2 via channel 9, because channel 9 is protected from contamination by the porous layer 7. This ensures that the follower plate 4 does not come into contact with the material 3, even when being extended from the container 2.
  • Another advantage is that significantly less force is required to pull out the follower plate 4, because the porous layer 7 remains in the container 2 and the follower plate 4 does not adhere to the porous layer 7 or the material 3 itself.
  • Channel 9 can be located in or below the follower plate 4.
  • Channel 9 can be connected to a vacuum generator via port 12 on the follower plate 4, allowing a vacuum to be created in channel 9. Air trapped when the follower plate 4 enters the container 2 can be extracted through channel 9 and the porous layer 7. This eliminates the need to vent the freshly introduced material, thus preventing material loss during venting. Furthermore, air inclusions in the conveyed material are prevented.
  • channel 9 is designed as a ring channel, this has the advantage that the negative pressure in container 2 can be distributed even more evenly.
  • the air contained in container 2 is extracted both axially from bottom to top through the porous layer 7 and radially through the porous layer 7. This allows air to be extracted from the space in the area of the piston plate 19 and also from the space in the pump 11 above the piston plate 19.
  • a separating layer 10 is arranged between the subsequent plate 4 and the porous layer 7.
  • the separating layer 10 significantly lengthens the path for material 2 through the porous layer 7 to the subsequent plate 4. This prevents material 2 from migrating through the porous layer 7 and contaminating the subsequent plate 4.
  • the separating layer 10 can be, for example, a plastic film or a coating on the porous layer 7.
  • the separating layer can be applied directly to the porous layer 7 or arranged above it.
  • the pump 11 is designed as a piston pump, it is preferably designed such that the piston plate 19 can be positioned in the porous layer 7 (see Figure 1 This allows the space above the scoop piston 19 to be easily vented.
  • the porous layer 7 remains in container 2 when the subsequent plate 4 is moved out of container 2. Because the adhesive forces generated by material 3 primarily act at the contact surface. Since the adhesive forces act between material 3 and the porous layer 7 (and do not engage with the subsequent plate 4), the pump jack does not need to overcome these adhesive forces to lift the subsequent plate 4. The subsequent plate 4 can therefore be moved out of the container 2 with significantly less force.
