Definitions

  • the invention relates to a device for conveying viscous material from a barrel-like container.
  • Such devices are used, for example, for applying adhesives, sealants, insulating materials, or thermal pastes to workpieces, particularly body components in motor vehicle production.
  • the viscous material is pumped out of the container via a material outlet opening by means of a pump.
  • a follower plate having the material outlet opening is constantly held in contact with a surface of the material in the container by means of a lifting and lowering device.
  • the follower plate is lowered by means of the lifting and lowering device to follow the falling material level in the container.
  • the follower plate is sealed off from the container shell so that, on the one hand, no material can escape from the container and, on the other hand, no air from the environment can enter the container. Once the container is empty, it is replaced with a new, full container.
  • the follower plate is first moved upwards out of the empty container and then inserted into the full container now positioned below it until it rests on the viscous material and the conveying process can begin.
  • the follower plate When inserting the follower plate into the full container, it is inevitable that air will be trapped between the follower plate and the viscous material, which must be removed before the viscous material is pumped out of the container.
  • the follower plate's circumference is sealed against the inner surface of the container shell facing the inside of the container, so that force must be applied when lowering the plate onto the surface of the viscous material.
  • DE 10 2018 104 763 A1 A device for conveying viscous material from a container is known, the follower plate of which has a ventilation opening and a ventilation device.
  • a device for conveying a viscous material with a rotating wiper ring on the follower plate is known from EP 3 296 075 A1 known, while from the DE 10 2007 003 972 B4 a device with a barrel pump and a follower plate is known, wherein the ventilation openings of the follower plate are covered by foam plates.
  • a covering layer made of a material permeable to air and impermeable to liquid is arranged on the underside of the follower plate, covering the vent opening(s) and/or the ventilation opening(s) and leaving the material outlet opening free.
  • the covering layer can be adapted to the viscous material. It must It should not be impermeable to every liquid, but only to the viscous material to be conveyed from the container.
  • the cover layer can be made of a foldable material, such as a thin layer of felt or a commercially available weed control fabric.
  • the cover layer is connected at its peripheral edge to a ring of elastically stretchable material.
  • the cover layer is preferably made of polypropylene (PP), in particular of thermally bonded continuous filaments.
  • PP polypropylene
  • a polypropylene layer with a weight according to DIN EN 29073 T.1 of 60 g/ m2 +/- 10% is preferred, which expediently has a maximum tensile strength according to DIN EN 29073 T.2 of 130 N/5 cm lengthwise and 90 N/5 cm crosswise, each +/- 20%, and an elongation according to DIN EN 29073 T.3 of 88% lengthwise and 87% crosswise, each +/- 20%.
  • Such a material is sold, for example, by p.
  • the follower plate When the follower plate is inserted, air is sucked out of the container interior through the cover layer, while the viscous material is retained in the container, thus reducing material waste.
  • the elastically expandable ring Before the follower plate is inserted into the container, the elastically expandable ring can be stretched and pulled over the peripheral edge of the container shell so that it is arranged circumferentially around the container shell on an outer side facing away from the container interior.
  • the follower plate When the follower plate is inserted into the container, it presses on the cover layer so that the ring is pulled away from the container shell and wraps around an outer surface of the follower plate.
  • the ring can then form an additional seal between the follower plate and the container shell.
  • the advantageous further development according to claim 3 is based on the idea of automatically switching between a movement mode in which The support rod(s) is/are lowered, particularly by motor drive, and alternately switches between a venting mode by means of the venting device to extract air from the container interior through the venting opening(s).
  • the follower plate is mounted in a floating manner relative to the lifting and lowering device and is vertically movable relative to it within a limited range.
  • the floating bearing is arranged between the follower plate and the at least one support rod, so that the follower plate has limited vertical movement relative to the at least one support rod, or for it to be arranged between the at least one support rod and a vertically movable support element of the lifting and lowering device that supports the support rod(s), so that it has limited vertical movement relative to the support element.
  • the follower plate is expediently connected to each support rod, or the at least one support rod is connected to the support element by means of at least one bolt guided in a vertically extending slot.
  • This is a simple yet reliable construction for the floating mounting of the follower plate on the at least one support rod, in order to fix it with limited vertical movement relative to the at least one support rod.
  • the sensor device has a distance measuring device for detecting the position of the follower plate relative to the at least one holding rod or relative to the support element. The distance measuring device measures the distance traveled by the follower plate relative to the at least one holding rod or relative to the support element and can thus determine the position of the follower plate relative to the at least one holding rod or relative to the support element and also the reaching of the upper and lower end positions with high accuracy.
  • the sensor device may have at least a first sensor for detecting the bolt or one of the bolts when the follower plate reaches the upper end position and at least one second sensor for detecting the bolt or one of the bolts when the follower plate reaches the lower end position.
  • the sensors are preferably proximity switches. They switch when the bolt or one of the bolts reaches either the lower or the upper end position.
  • each support rod be received at its lower end in a sleeve fixed to the top of the follower plate, and that at least one bolt protrudes radially from it and is guided in an elongated hole in the sleeve.
  • the sleeve can, for example, be screwed to the follower plate.
  • each support rod is also possible, and particularly advantageous for smaller devices, for each support rod to be received at its upper end in a sleeve fixed to a vertically movable component of the lifting and lowering device, in particular to the underside of a cross member.
  • at least one bolt protrudes radially from the at least one support rod and is guided in an elongated hole in the sleeve.
  • at least two bolts protrude radially from each support rod at equal angular intervals from one another, each of which is guided in an elongated hole in the associated sleeve.
  • two bolts can project radially from each support rod in opposite directions.
  • the lifting and lowering device comprises a plurality of support rods, which are preferably arranged concentrically and at equal distances from one another around a center point of the follower plate.
  • the support rods extend at equal distances from a central longitudinal axis of the essentially cylindrical follower plate.
  • two support rods can be provided, which are diametrically opposite one another with respect to the center point or central axis.
  • the follower plate can be equipped with a sensor to detect when it has touched the container floor.
  • This sensor has a pin protruding from the underside of the follower plate that can be moved into the follower plate against a restoring force. The pin triggers the sensor signal when the follower plate rests on the container floor with its full weight and the pin is pressed into the follower plate.
  • vent opening and at least one vent opening spaced apart from it may be provided.
  • the vent opening(s) and the vent opening(s) coincide, so that at least one opening is present in the follower plate for the introduction and extraction of air.
  • the venting device can be, for example, a compressor or a Venturi nozzle. It is also possible to design the venting device so that it can be operated in the reverse direction and introduces compressed air into the container interior. However, it is also possible to supply the compressed air via a separate compressed air line.
  • the device 10 shown in the drawing is used to convey viscous material from a barrel-like container. It has a follower plate 12 that can be raised and lowered by means of a lifting and lowering device 14.
  • the lifting and lowering device 14 has a base plate 16 and hydraulic cylinders 18 mounted on the base plate 16, whose piston rods 20 extend upward and are connected to one another by a support element 22 in the form of a cross member. Two support rods 24 extend downward from the cross member 22, from which the follower plate 12 is suspended.
  • the follower plate 12 has a central material outlet opening 26 through which the viscous material can be pumped out of the container by means of a scoop piston pump 28 when the follower plate 12 rests with its underside on the viscous material. It also has several venting openings 30 through which air can be pumped out of the container interior and compressed air can be introduced into the container interior. A venting device (not shown in detail) or a ventilation device can be connected to the venting openings 30.
  • the follower plate 12 is not rigidly connected to the support rods 24, but is mounted on them in a floating manner in the sense that it has limited vertical movement with respect to the support rods 24.
  • two sleeves 34 are screwed to the upper side 32 of the follower plate 12, each of which receives the lower end of one of the two support rods 24.
  • a bolt 36 projects radially from each of the support rods, which bolt passes through a vertically extending slot 38 in the respective sleeve 34 and is guided therein for longitudinal displacement in the vertical direction.
  • the slot 38 is covered on the outside by a cover cap 40.
  • the follower plate 12 can be arranged between a Fig.
  • a sensor device in the form of a position measuring device 42 on each sleeve 24 detects the position of the follower plate 12 with respect to the holding rods 24 and in particular the reaching of the upper end position and the reaching of the lower end position by the follower plate 12.
  • the position measuring device 42 sends signals to a control device (not shown in detail) when the respective end position is reached by the follower plate 12.
  • the follower plate 12 is lifted from the base plate 16 by means of the lifting and lowering device 14, and the upwardly open container is placed beneath the follower plate 12 on the base plate 16.
  • a cover element 50 is then arranged to cover the upwardly open container.
  • the cover element 50 has a cover layer 52 that is permeable to air but not to the viscous material.
  • the cover layer 52 is thin and consists of a foldable material such as a commercially available weed control fabric or a thin layer of felt.
  • An elastically expandable ring 54 runs around the cover layer 52 and is pulled over the outer surface of the container so that, when stretched, it rests against the outer surface.
  • the follower plate 12 is then lowered, presses on the cover layer 52 and thus pulls the elastic ring 54 away from the outer surface of the container until it rests against the outer surface 56 of the follower plate 12, as shown in Fig. 4 shown.
  • the covering layer 52 covers the ventilation opening 30, but not the material outlet opening 26.
  • the follower plate 12 is lowered by means of the lifting and lowering device 14 until a wiper ring 58 encircling its outer surface 56 comes into contact with the inner surface of the container shell, so that its frictional force inhibits further insertion of the follower plate 12.
  • a further lowering of the support rods 24 brings the follower plate 12 into its upper end position, so that the position measuring device 42 is triggered and the control device the venting device is activated and the lifting and lowering device 14 stops. Due to the negative pressure created in the container, the follower plate 12 is pulled downwards until it reaches its lower end position, so that the position measuring device 42 is triggered, the control device deactivates the venting device and controls the lifting and lowering device 14, which lowers the support rods 24.
  • the conveying process then begins, during which the scoop piston pump 28 pumps the viscous material out of the container.
  • the follower plate 12 follows the material level until it reaches its lower end position, whereupon the control device, based on a signal from the position measuring device 42, activates the lifting and lowering device 14, so that the support rods 24 are lowered until the follower plate 12 reaches its upper end position and the position measuring device 42 transmits a corresponding signal to the control device.
  • the control device based on a signal from the position measuring device 42, activates the lifting and lowering device 14, so that the support rods 24 are lowered until the follower plate 12 reaches its upper end position and the position measuring device 42 transmits a corresponding signal to the control device.
  • at least one hold-down device can be provided, which is firmly connected to the base plate 16 and engages a lower and/or upper container edge.
  • the follower plate 12 is removed from the container in the same way as when inserting the follower plate 12 into the container.
  • compressed air is introduced into the venting opening 30 by means of the venting device, causing the follower plate 12 to lift from the container floor under pressure. It then reaches its upper end position, the position measuring device 42 switches, the control device interrupts the compressed air supply, and activates the lifting and lowering device 14, which raises the support rods 24 until the follower plate 12 returns to its lower end position.
  • the position measuring device 42 switches again, the lifting and lowering device 14 is stopped and compressed air is again introduced into the interior of the container and so on until the follower plate 12 reaches the upper edge of the container and can be lifted off.
