Definitions
- the invention relates to a device according to the preamble of the claim 1.
- Outlet openings When using and processing bulk goods, they can be dosed discharged from containers and silos through outlet openings. These are at the Outlet opening, or at an emptying station on which the container with the outlet opening can be placed, operable outlet devices are arranged.
- This Outlet devices comprise a housing part through the emerging bulk material in the further investment area. There is an upper part on the housing Opening or an inlet opening formed.
- the closing member preferably comprises a conical guide surface, which faces the bulk material in the container and the bulk material when it flows out conducts against the annular outlet channel.
- the outlet device preferably comprises an oscillating device, which makes the closing member oscillate.
- the actuator comprises a piston-cylinder arrangement.
- This piston-cylinder arrangement tends but with an asymmetrical load due to bulk material to jam.
- the leadership this arrangement is defined by an annular area of the piston and an annular area given in the implementation of the piston from the cylinder part. Because the distance of these two guide areas is the smallest when the closure member is lifted off leadership stability is smallest when, due to the Swinging movement of the closing device and the movements of the bulk material force are largest across the piston axis.
- Another disadvantage is that the Guide areas as sealing areas during piston movements high frictional forces produce. Therefore, both the lifting and the touchdown movement must be done by means of Pressurization of the respective piston side can be actuated. That means it must a bilaterally actuable piston-cylinder arrangement with the corresponding Control can be used.
- the invention is based on the object of an outlet device for metering Skipping bulk to find that is simple, not jammed, and quick locking ensures.
- a rolling membrane is so thin and flexible can that the internal resistance to the deformation required during piston movement is very small. Accordingly, with a piston-cylinder arrangement in which the piston is connected to the cylinder via a roller membrane, an extremely short one Capping time can be guaranteed. This means that after the termination of the Pressurizing the space sealed off by the membrane between the Cylinder and the piston, the piston slides down substantially unimpeded. Comparisons have shown that when using a bellows, a shutter speed of up to to 2 seconds and when using a roller membrane a shutter speed of only 0.2 seconds can occur. When using a rolling membrane, the rolling membrane should only perform the sealing function between the cylinder and piston.
- the piston-cylinder arrangement therefore includes a linear guide unit with constant guiding properties independent of the piston position. This prevents jamming.
- This linear guide unit includes for example a rod which is guided in a guide sleeve. The should Always extend the rod completely through the guide sleeve in each piston position.
- the Leadership leaves essentially no or only so little play that the rolling membrane between the outer surface of the piston and the inner surface of the cylinder can, or that the rolling behavior of the membrane is not impaired.
- the actuator is simple and functionally reliable even with little maintenance. Since the closing is passive, is the control, or the supply with pressurized fluid, is extremely simple. In addition can the linear guide device with little effort for each system desired maximum lifting height can be set. It is also possible this maximum Design the lifting height to be automatically adjustable. If the passage opening or the Lifting height can be adjusted according to the respective bulk material or its emptying resistance precise dosing is also possible for different bulk materials.
- connection lips 3 for connection formed the connection area of a container.
- the outlet device shown attachable containers have an outlet opening at the bottom, which are closed by a closure member placed on the inside of the container is.
- An outlet device 1 connected to a container can such closure member can be lifted off the outlet opening.
- the exit opening the container an inlet opening 4, or an upper opening of the Associated housing part 2, so that when the closure member is lifted bulk material gets from the container into the housing part 2.
- an actuator for lifting and lowering the locking device is an actuator with a piston-cylinder arrangement 5 provided. It goes without saying that the outlet device too can be formed as part of a container or a silo.
- the piston-cylinder arrangement 5 consists of a lower cylinder part 6 on the one sleeve-shaped upper cylinder part 7 is placed. Between the two cylinder parts 6, 7, an annular first fastening region 8 is formed for a rolling membrane 9. In the two cylinder parts 6, 7 there is a piston part 10 with a cylindrical outer surface 11 arranged. On the piston part 10 there is a second fastening area 12 for the Roll membrane 9 provided. In the illustrated embodiment, this is the second Fastening area 12 on the lower end face of the piston part 10 circular inner edge of the rolling membrane with an annular clamping element 13 clamped on the piston part 10.
- the rolling area of the rolling membrane 9 leads from second fastening area in a gap area 14 between the piston and the Cylinder parts 10 and 7 slightly upwards to a folding area 15 of the membrane 9 and from there down to the first fastening area 8.
- the gap area is like this formed that the rolling membrane 9 substantially when the piston part 10 moves can perform smooth rolling movements. or the transfer area 15 unhindered can be moved up and down.
- a gap width that is too large is not practical, because then the forces from the pressure fluid on the transfer area 15 due to the small Thickness of the rolling membrane 9 could lead to undesirable deformations.
- One to the Roll membrane 9 adapted gap width ensures a defined rolling behavior the rolling diaphragm 9. By tightly connecting the rolling diaphragm 9 to the piston part 10 and the cylinder parts 6, 7, it is ensured that the cylinder interior when Piston part 10 is tightly sealed to the outside.
- a linear guide unit is used to exactly guide the movement of the piston part 10 in the cylinder 6, 7 16 provided with a sleeve part 17 and a rod 18 guided therein.
- the piston part 10 is fastened to the rod 18 in the region of a first notch 18a.
- a first ring part 19 connectable to the piston part 10 on the first notch 18a set.
- a seal 20 is arranged between the rod 18 and the piston part 10.
- the sleeve part 17 is tightly connected to the lower cylinder part 6 and so arranged that the axis of the sleeve part 17 coincides with the axis of the cylinder part 6. In the illustrated embodiment is in both end regions of the sleeve part 17 each a guide bush 17a, 17b arranged.
- the rod 18 always extends completely through the sleeve part 17. This ensures that the leadership qualities for all possible Piston positions remain the same. It is a precise and unclampable Guide. With a longitudinal groove 18c in the rod and one from the sleeve 17 into the groove 18c projecting pin 18d is an anti-rotation device between the rod 18 and the sleeve part 17 scored. Around a sufficiently long management area even with a small overall height to enable, the sleeve part 17 extends through the interior of the cylinder part 6. So that the lower end of the piston part 10 is still close to the lower Cylinder end surface is movable, is a central recess in the piston part 10 trained for the sleeve part.
- the rod 18 In the lower end region of the rod 18 there is at least one stop, preferably but can be attached to different rod positions. There are second notches in the rod 18b trained. According to the desired maximum stroke, the Installation in a notch 18b, a snap ring 21 is inserted, on which a stop sleeve 22 can be set. The stop sleeve 22 strikes when the maximum is reached Hubes against an elastic damping element 23 at the lower end of the sleeve part 17 is arranged. In order to seal the sleeve part 17 tightly downwards there is attached an end sleeve 24 which is dimensioned such that the rod 18 also there is space in the lowest piston position. To get the maximum stroke even after assembly, It may be necessary to be able to adjust, especially during operation an adjustable stop device described below with reference to FIG. 2 intended.
- a plate or a first disk 25 is attached to the upper end region of the rod 18. Via elastic connecting elements 26 there is one on the first disk 25 overlying plate, or a second disc 27 attached. On the second disc 27 is a vibrating device 28 and a conical cover 29 is mounted above it. The upper edge region of an annular one runs around the outside of the second disk 27 Inflatable seal 30 which interacts with a closure member to be lifted off and makes the inlet opening 4 or the upper opening closable in a dust-tight manner.
- the Closing member accessible from below is adapted to the shape of the cover 29. It goes without saying that the cover 29 also directly covers the closing member could form, especially if the outlet device as part a silo is formed.
- the closing member can be from the vibrating device are set in vibration.
- the connecting elements 26 selected so that a sufficiently strong swing of the Closing member, or the cover 29, also with the substantially fixed first disc 25 is possible.
- an elastic seal 31 is provided extends from the cover 29 to the cylinder parts 6, 7.
- the bracket of the actuator or the piston-cylinder arrangement 5 is done at least in part by means of four tubular struts 32. These struts 32 are simultaneous designed as fluid lines.
- the fluid line of a strut 32 is Feed line 33 inserted through a bore 34 in the first cylinder part 6 in the Interior leads.
- a connecting line 36 connected to the vibrating device 28.
- the vibrating device 28 releases pressurized fluid that flows through a discharge line 37, a connection bore 35 'and through the interior of a strut 32 from the interior of the housing part 2 is dissipated.
- the inflatable seal 30 is also pressurized by a Strut 32.
- the vibrating device preferably requires a minimum feed pressure that only at the end of the lifting process, that is when the stop sleeve 22 abuts the stop, is achieved.
- the pressure in the supply line 33 reduced to ambient pressure, or the pressure fluid can be drained.
- Pressurized fluid is preferably compressed air. Because the reset movement is due to due to the easy mobility of the rolling membrane without active actuation gravity takes place extremely quickly, the control can be very simple, in essentially with a valve that connects the supply line alternatively to the pressure source or connects the environment.
- Fig. 2 shows an embodiment with a lifting height adjustment device 40 it enables the lifting height that can be achieved when opening, if necessary before or during Open to adjust each.
- a lifting height adjustment device 40 instead of one on rod 18 in different positions lockable stop sleeve 22, is one with your internal thread in an external thread 41 of the rod 18 matching continuously adjustable stop sleeve 22 'is provided.
- a motor preferably a pneumatic motor 42 with an axis of rotation 43 coinciding with the rod axis in the end sleeve 24 arranged.

- a disk part 45 On the drive axle 44 a disk part 45 and attached to this a driving sleeve 46.
- a longitudinal slot 47 is formed, into which a radially projecting groove part 48 engages the stop sleeve 22 '.
- the driving sleeve 46 rotates, the groove part 48 rotated in the longitudinal slot 47.
- the stop sleeve 22 ' moves on the External thread 41 of the rod 18 along its longitudinal direction. Moves accordingly the groove part 48 along the longitudinal slot 47.
- the maximum stroke of the rod 18 depends on the respective position of the stop sleeve 22 'and is applied the stop sleeve 22 'reaches a stroke stop 49 of the sleeve part 17.
- a Rotating the rod 18 and accordingly a rotation of the rolling membrane 9 is preferably prevented by an anti-rotation device.
- the driving sleeve 46 is rotatably mounted in the sleeve part 17 with little play. Therefore can between the stop sleeve 22 'and and the inside of the driving sleeve 46th an exact guide area 17b 'for the opening and closing movement of the rod 18 are trained. With the guide area 17b 'and the guide sleeve 17a an exact straight guidance of the rod 18 can be ensured.
- This exact Leadership is in the combination of the lifting height adjustment device 40 with the piston-cylinder arrangement 5, which comprises a rolling membrane 9, advantageous and easy to achieve.
