Definitions

  • the invention relates to the emptying of highly viscous, ie pasty, substances from delivered containers, in particular barrels.
  • the front side which is open in principle, is usually closed by an axially movable, tightly closing, stopper, and in addition the cartridge usually has a removal opening on the opposite front side.
  • Barrel presses are already known in which a press plate is placed on the viscous material in the barrel to be emptied, which z. B. in the middle has a through opening to which a delivery line for the viscous material is connected.
  • This pressing plate is designed to fit tightly on its outer circumference relative to the inner circumference of the barrel. By pressing down the pressure plate with sufficient force and corresponding to the path, the viscous material is pressed into the delivery line and delivered in this way to the consumer removed from the barrel in the desired quantity and with sufficient pressure at the consumer, depending on Length of the delivery line in the course of which one or more pumps can also be arranged.
  • this object is achieved in that the conveying line is not attached directly to the through opening of the press plate.
  • the press cylinder moves into the container together with the press plate when the container is emptied, the press cylinder has a free inner diameter that is smaller than the free inner diameter of the container to be emptied, and the outer circumference of the press cylinder is also included positioned a radial distance from the outer edge of the press plate, so set back radially inward.
  • a delivery piston is axially displaceable close to the inner circumference of the press cylinder, just like the press plate itself, both in the conveying direction and in the retraction direction, and is driven by its own conveyor drive, which can be controlled independently of the press drive, which moves the press plate axially .
  • a through opening is arranged, mostly in the center, on the rear side of which the delivery line is tightly fastened, through which the material to be removed can flow.
  • one or more check valves are provided in the press plate so that the material only penetrates the press plate from the front to the rear, i.e. usually from bottom to top, i.e. in the direction of the delivery piston can, but not the other way around.
  • the check valves should preferably not protrude beyond the rear of the press plate and / or not beyond its front.
  • the press plate and delivery piston are brought into their starting position.
  • the seal between the outer circumference of the delivery piston, which can be precisely matched to one another, and the inner circumference of the press cylinder - which can also be made more stable than a barrel - is, however, generally much more resilient than the seal of the press plate against the interior circumference of the barrel, which is subject to great manufacturing inaccuracies.
  • the starting position, the target position and the target position of the delivery piston can of course preferably be adjustable, as can the distance that the press plate takes in each delivery process.
  • the pressure in the material is measured to control the process, for example on the front of the press plate and / or on the front of the delivery piston and / or in the delivery line, be it close to the delivery piston and / or close to the consumer.
  • the movement of the press plate and / or delivery piston is controlled with regard to the time sequence, duration and speed of these components.
  • the space in between is subjected to negative pressure or the entire container to be emptied is sealed in an enclosure at least with its open side recorded, which is acted upon with negative pressure above all before and when the press plate is placed on the material in the interior in order to reliably avoid air inclusions.
  • the inner diameter of the press cylinder is by no means as large as possible relative to the inner diameter of the container to be emptied, in particular the barrel, but preferably at least 5%, better at least 10%, better at least 15%, better at least 20%, better at least 30% smaller chosen to keep the circumferential length of the seal between the delivery piston and press cylinder as small as possible.
  • the press plate drive and the conveyor plate drive can be controlled independently of one another and preferably contain one or two parallel threaded spindles as a drive element or a working cylinder, for example a hydraulic cylinder or a pneumatic cylinder.
  • Simple ball valves or other forms of check valves can be provided as check valves.
  • the check valves should not protrude beyond the back of the press plate - otherwise the delivery piston could not be moved all the way to the back of the press plate - and / or not protrude over the front of the press plate - otherwise the front of the press plate would not completely touch the Bottom of the barrel could be approached.
  • the pressure plate should preferably have such a thickness in the axial direction that the one or more check valves have full space in it in the axial direction.
  • the sum of the free passages of the total check valves - which may only be located in the radial area within the free diameter of the press cylinder - should be at least 15% in their open state, better at least 20%, better at least 30%, better at least 40%, better at least 50% of the bottom surface of the press cylinder.
  • the safest solution is to make the press plate in one piece with the press cylinder, which, however, requires a lot of manufacturing effort and is usually only chosen for extremely thin-bodied materials.
  • the press plate is preferably fastened to the press cylinder in a simple manner so that it can be detached, that is, it can be both dismantled and assembled.
  • the press plate can be removed from the press cylinder for cleaning purposes.
  • a corresponding press plate can be attached to the press cylinder so that the emptying device can be used for drums of different diameters.
  • pressure sensors are used on the one hand, in particular at the aforementioned points, and on the other hand position sensors that are present either on the press plate and / or on the delivery piston, and with which the axial position on the one hand of the press plate within the emptying device, i.e. when in use relative to the barrel, and on the other hand the axial position of the delivery piston relative to the press cylinder.
  • a peristaltic pump which acts on the hose from the outside is preferably provided in the conveying line, which consists at least in sections of a flexible hose.
  • a vacuum connection can be provided in the front of the press plate - radially away from the area of the press cylinder - and / or in the conveying line.
  • the frame of the emptying device also comprises a housing into which either the entire container or at least the part of it containing the open side of the container is placed and at least the open side is tightly closed can be.
  • the housing has a vacuum connection via which the interior of the housing can be connected to a vacuum source.
  • the inner surface of the delivery line can have a friction-reducing surface design.
  • a buffer for material is preferably present in the conveying line in order to be connected to the material from the buffer even when the conveying piston is stationary in the press cylinder To continue to supply consumers with material from the buffer.
  • Such a buffer in the delivery line can for example be a piston pump or a diaphragm pump with a sufficiently large volume.
  • the piston rod of the delivery piston and possibly even the press cylinder, will then have to extend through the housing.
  • FIGS. 1a , b, c and 2 show an emptying device in the form of a barrel press in external views and in sectional views:
  • Material 52 should be made from the Figures 1a and 2 shown, open-topped, barrel 50 are promoted by the press plate 2 , which is in the inner circumference of the barrel 50 can be pushed in tightly from above, and exerts pressure on the material 52 with its pressure side 2a , so that this - as best shown in FIG Fig. 2 to be seen - is then pushed upwards by the hollow piston rod 17 protruding from the opposite rear side 2b and through the feed line 4 connected to it to the only in the Fig. 2 indicated consumer 53 is pushed.
  • the barrel 50 is first set in a housing 6 , which consists of a solid housing 6 a and the door 6 b shown here in the pivoted state, which in the closed state Housing 6 seals, in the interior 9 of which the desired negative pressure is generated.
  • the housing 6 has a vacuum connection 7 , via which the housing 6 is connected to a vacuum source 8 .
  • the only element extending through the top of the housing 6 into the interior 9 is the piston rod 17, at the front end of which the pressure plate 2 is attached and which moves the pressure plate 2 , the passage being sealed accordingly to prevent air from outside into the to let penetrate under pressure interior 9 .
  • the housing 6 is located in a solid frame 1 , in the upper area of which there are two vertically arranged parallel lines next to each other Threaded spindles 15 or ball screw spindles are arranged, which act together on a transverse yoke 12 , which is connected to the rear, upper end of the hollow piston rod 17 , which extends up to the pressure plate 2 .
  • the press plate seal is not completely tight due to the deformation of the barrel, and in addition such a stable enclosure 13 not only creates an expense in the manufacture of the machine, but also, depending on the dimensions of the barrel 50 , mostly for the barrels from different manufacturers, a separate matching enclosure 13 is required.
  • barrels have a relatively large range of fluctuation in their actual dimensions, especially with regard to wall thickness, inner diameter and outer diameter.
  • a design of the emptying device according to Fig. 3 suggested having the same view as Fig. 2 used: It can be seen that a press cylinder 22 extends from the rear side 2b of the press plate 2 upwards, i.e. in the retraction direction 10b of the axial direction 10, and in the cross section of the press plate 2 within the inner circumference of this press cylinder 22 for the material 52 to be conveyed at least one, usually several, through-openings 3 are present, which are now each designed as check valves 19 , in this case with a ball 19a as the valve body.
  • the flow direction of this at least one check valve 19 is exclusively the direction from bottom to top, that is to say into the interior of the press cylinder 22 , and not vice versa.
  • the pressing plate 2 is about usually several in the axial direction 10 consecutively arranged press plate seals 14 on the inner circumference of the wall 50b of the barrel 50 slidably mounted.
  • the press cylinder 22 is hollow in the axial direction 10 and a press piston 24 is guided in it so that it can be moved in the axial direction, sealed by a plurality of delivery piston seals 23 arranged one behind the other in the axial direction .
  • the delivery piston 24 has a central through-opening 3 ' which opens into the axially hollow piston rod 17 extending upwards from the plunger 24 , i.e. in the retraction direction 10b, to which the delivery line 4 is connected in its upper, downstream end area leads to consumer 53 .
  • the pressing plate 2 on the one hand and the delivery piston 24 on the other hand can be moved independently of one another in the axial direction 10 both in the pressing direction 10a and in the retraction direction 10b.
  • the positions of the delivery piston 24 and the press plate 2 can be monitored by one or a common position sensor 55 , one of which is shown in FIG Figure 3 one is arranged on the housing 6 next to the through opening for the piston rod 17 and the other on the piston rod 17.
  • a pressure sensor 54 can also be present, for example in the underside of the delivery piston 24 , to measure the pressure in the material 52 below.
  • the movement takes place either by means of a common drive 5 , but nevertheless independently of one another insofar as either the press cylinder 22 , i.e. the piston rod of the press plate 2, or the piston rod 17 of the delivery piston 24 or both can be coupled simultaneously with this common drive 5 .
  • the press cylinder 22 is slidably sealed in the axial direction in the passage in the upper side of the housing 6 , as was also the case in the solution according to the prior art with the piston rod 17 of the press plate 2 .
  • This process can be performed according to the Figures 4c and d can be repeated one or more times.
  • the press plate 2 is then moved down until it rests on the bottom 50a of the barrel 50 , then stopped and the delivery piston 24 lowered until it rests on the rear 2b, the top, of the press plate 2 .
  • the barrel is thus emptied, the pressing plate 2 can be moved upwards out of the barrel 50 and the empty barrel 50 can be exchanged for a full one.
  • a spindle nut 25 through which the threaded spindle 15 extends, can be fixedly mounted in the frame 1 .
  • Each of the two threaded spindles 25 is in the present case driven by a separate electric motor 16 , the rotations of the two spindle nuts 25 , which cause the axial movement of the threaded spindles 15 , are mechanically synchronized by a synchronous connection that acts between the two spindle nuts 25 and is operatively connected to both, in particular in form a clutch.
  • a position sensor 21 is disposed, consisting for example of a sensor bar 21 a which is fixed to the inside of the frame 1 and a position transmitter, for example a position magnet 21 b, in the case of a magnetostrictive sensor, which moves in the vertical, i.e. axial, direction when the unit of threaded spindles 15 , yoke 12 , piston rod 17 and pressure plate 2 moves downwards along the sensor strip 21 a and thus the position of the press plate 2 is detected so that the press plate 2 can be stopped when it has reached the bottom of the barrel 50 and this is thus emptied.
  • a position sensor 21 consisting for example of a sensor bar 21 a which is fixed to the inside of the frame 1 and a position transmitter, for example a position magnet 21 b, in the case of a magnetostrictive sensor, which moves in the vertical, i.e. axial, direction when the unit of threaded spindles 15 , yoke 12 , piston rod 17 and pressure plate 2 moves downwards along the sensor
  • the conveying line 4 conveying away the material is attached to a corresponding connection piece of the yoke 12 , so that the conveying line 4 usually consists of a flexible but high-strength hose that is led away from the rear of the frame 1 , as in the Figures 1b and 2 shown.
