Definitions

  • the invention relates to a device for metering in, in particular, powdery filling goods.
  • a device of the generic type is known, for example, from DE-A-35 43 507.
  • This known device works perfectly, but has the disadvantage that only two opposing rows of cylinders can be arranged in the drum, the stroke adjustment must take place inside the drum and that the drum, because it has no supporting shaft because of the adjusting crossbars, one Circumferential drum storage required.
  • the performance of such a metering device is limited insofar as it can only be filled at the top and emptied at the bottom, and it takes half a revolution of the drum to bring empty cylinders back into the filling position and around filled cylinders into the emptying position.
  • Central shaft metering devices are known from US-A-3 154 117 and 4 052 836.
  • the invention is based on the object, in spite of the use of piston actuating traverses improve that more than two rows of diametrically opposed cylinders can be provided on the drum, the suction or metering stroke should also be adjustable independently of the exhaust stroke.
  • a device of the generic type according to the invention in that the drum is supported on both ends by means of a straight number of at least four radial spokes corresponding to the number of rows of cylinders on a shaft which passes centrally through the drum and one each on the spokes of a pair of spokes Piston actuating crossmember is displaceably guided and that in the travel of the crossbeam rollers transverse to the shaft a control lever effecting the full ejection stroke and a further control lever causing the suction stroke are arranged, the lever adjustments causing rotating control curves for synchronous rotation being coupled to one another and the control curve causing the suction stroke with respect to the relevant control lever is arranged adjustable.
  • the drum is carried by a central shaft to be supported normally and at least four rows of cylinders can be provided and thus the throughput can be increased accordingly, results from the adjusting and actuating mechanism to be explained in more detail below that the suction or metering stroke can be set in a simple manner and completely independently of the emptying stroke.
  • the main basic idea here is to have the actuating element which effects the emptying stroke always carry out the full stroke deflection, regardless of the metering stroke setting to which the pistons have previously been set, which will be explained in more detail below.
  • the at least four piston actuating crossbeams are guided on the spokes with ball guide sleeves.
  • the necessary positioning curves can advantageously be designed for both processes in the same shape and size and eccentricity, since the suction stroke setting is not achieved by a different curve configuration, but this suction stroke setting is only achieved by adjusting the distance of the suction stroke curve to the respective active position located piston actuation crossbar. Otherwise, these control curves can be designed as simple eccentric circular disks. This distance adjustment could be realized per se by the fact that the axis of rotation of the positioning curve for the suction stroke is mounted in an appropriately adjustable manner on the device frame.
  • the second, higher-level control lever can be mounted on the same axis as the control curve causing the emptying stroke and there is no need to take into account the required synchronous coupling of the two control curves, which would otherwise be achieved by a correspondingly curved slot guide on the device frame for the storage and guidance of the suction stroke effecting curve should be taken into account.
  • the actuating lever causing the ejection stroke is a two-armed, essentially pivotable angular lever, one end of which rests against the cam and the other arm at the end of which is traversable by one of the truss rollers Transverse process is provided.
  • rollers arranged on one side of all traverses run from below against the actuating lever causing the suction stroke when the drum is rotated, and the transverse extension arranged on the other actuating lever causing the ejection stroke is driven under by the rollers coming from above in incremental rotation.
  • the device consists of a drum 2 rotatably arranged under a product feed device 1 with product receptacles open to the outside in the form of radially opposed cylinders 3 with pistons 4 and piston rods 5 adjustable in terms of their stroke, the pistons 4 of a row of cylinders 3 'with their piston rods 5 each a piston actuating crossmember 6 extending inside the drum 2 are fastened, which can be brought into operative connection outside the drum 2 via rollers 7 with lifting movement elements.
  • the drum 2 is of course provided at least on the side on which the filled cylinders 3 move downwards with a suitable cover A.
  • the drum 2 is supported on both ends by means of a straight number of at least four radial spokes 8 corresponding to the number of cylinder rows 3 'on a shaft 9 which passes centrally through the drum 2 and on the spokes 8 of a pair of spokes 8'.
  • one piston actuating crossmember 6 is slidably guided.
  • the traverse rollers 7 are transverse in the travel to the shaft 9, an actuating lever 10 effecting the full exhaust stroke and another actuating lever 11 effecting the suction stroke are arranged, the rotatable adjusting curves 12, 12 'effecting the lever adjustments being coupled to each other for synchronous rotation and the adjusting curve 12' effecting the suction stroke being adjustable with respect to the adjusting lever 11 is arranged.
  • FIGS. 1, 2 there are a total of (see FIGS. 1, 2) twenty-four cylinders 3 with pistons 4 and piston rods 5, four cylinders in each case being arranged in series (see FIG. 2) and each row having a pair of spokes 8 ′ with the associated actuating cross member 6 assigned.
  • Each cross member 6 is guided at its ends by means of ball guide sleeves 13 on the associated spokes 8, all spokes 8 holding the shaft 9 in the longitudinal center axis of the drum 2.
  • control curves 12, 12 ′ are designed, for example, in the form of eccentrically mounted circular disks 14.
  • the actuating lever 10 causing the ejection stroke is a two-armed, essentially pivotally mounted angular lever, one arm 10 'of which rests on the cam 12 with its end and the other arm 10' 'of which ends with one of the Traverse rollers 7 is provided under the transverse extension 15 (see also Fig. 3).
  • a second control lever 11 ′ which is pivotably mounted at the opposite end and has an opposite direction of extension, is superordinate to the control lever 11 which causes the suction stroke, and its end 17 located above the pivot bearing 16 of the control lever 11 with respect to the pivot bearing 16 is designed adjustable in distance.
  • the control curve 12 'acting on the end of the control lever 11 located below it is arranged on the control lever 11'.
  • the control curves 12, 12 ' for example designed as eccentrically mounted circular disks 14, are connected, for example, to a chain drive 14', that is to say they rotate synchronously in step cycle, these disks 14 with respect to their eccentricity and when arranged the control lever are arranged offset by 90 ° as shown.
  • the superordinate control lever 11 'with its pivot bearing end 18 is mounted on the same axis 19 as the rotatable control cam 12 for the control lever 10, ie when the distance between the two control levers 11, 11' is adjusted by means of an adjusting spindle 20, the control lever 11 'in the direction of arrow P pivoted about the axis 19 and thus also the control curve 12 is raised.
  • the setting lever 11 is always in the highest position, i.e. the position in which the pistons 4 of a row 3 'close the cylinders 3 at the top when the filling position under the product feed device 1 is reached.
  • the adjusting lever 11 ' is now set, when the adjusting curve 12' is rotated, there is a more or less deep suction stroke of the pistons 4. Since the other adjusting curve 12 also rotates, there is a transverse extension 15 in the row of cylinders below via angled lever 10 , Role 7 and associated cross member 6 the emptying stroke.
  • the pistons 4 are guided tightly in their cylinders 3 so that they maintain their dosage setting specified by the adjusting lever 11.
