Definitions

  • the invention relates to a filling machine for filling open large bags with a filler neck, at the lower edge of which the large bag to be filled can be attached is.
  • the large bags to be filled by means of the filling machine in question are in also known as Big Bags in the industry. They are made of a highly resilient material made, preferably from a ribbon fabric. Usually be the large bags are filled with 1000 kg of a filling material. The dimensions of the large bags depend on the specific weight or the weight of the filling material. It it cannot be prevented that, preferably due to static charging, The product settles on the inner surface of the filling channel. At the end of the filling process vibrations occur when the large sack is removed and closed the filler neck. The adhering to the inner surface of the filling channel Product particles are then loosened so that they rest on the ones underneath Fall sack. The trickling filling can have a weight of several Make up kilograms.
  • the invention has for its object a filling machine closer to the beginning described type in a structurally simple manner so that a trickle of filling material, in particular of adhering to the inner surface of the flow channel Filling material, is effectively avoided, and that the appending of the filling Large bags on the filler neck is facilitated.
  • the task is performed by at least one in the lower area of the filler neck arranged closing element solved, which by means of a controllable Actuator in a position releasing and closing the flow opening can be brought, and that at least the area enveloped by the attached large bag of the filler neck in an inclined position inclined to the vertical is pivotable.
  • the through-flow channel now becomes immediately after the end of the filling process closed by the closing element.
  • the actuator can be controlled accordingly be so that the closing member is already moved into the closed position is released when the so-called sack buckle securing the sack to the filler neck becomes.
  • the closing element can be moved into its open position as soon as the next sack to be filled is placed on the filler neck. What was held back until then The filling material then falls into the empty sack. It is necessary to expand it of the empty sack this is pressurized.
  • the closing organ supports the formation of overpressure, so that on additional elements can be dispensed with.
  • the large sack is attached to the filler neck from a platform. There now at least the area of the filler neck covered by the large sack its central longitudinal axis in a vertical inclined position can be brought, the operator is much easier to attach, as the filler neck is pivoted towards the operator can.
  • the closing element expediently consists of two flaps, two horizontal, parallel and spaced axes that are mutually pivotable.
  • Closing flaps existing closing element offers the advantage that in preferred Execution through each closure flap only half the outlet opening or half the cross section of the flow channel must be closed, so that the Closure flaps then still above the level in the open state stand when the weight of the sack is reached because of a certain length is necessary for the closure of the filled large bag.
  • the flow channel the filler neck is circular in a preferred embodiment. If the closure element consists of two flaps, it makes sense if these are of size are the same or approximately the same and that they are therefore semicircular or are designed almost semicircular. So that no material through the joint in the closed state of the flaps, it is provided that the Overlap the edges facing away from the actuators a little.
  • each closing element by means of its own actuator, preferably by means of a Linear actuator can be actuated.
  • a Linear actuator a pneumatically operated piston-cylinder unit in question. So that the linear drive or the linear drives are protected as well as possible against dust and dirt are, it is provided that each actuator at a distance from the outflow opening the filler neck, i.e. the linear drives are in the upper area of the Filler neck arranged.
  • Each linear drive or each piston-cylinder unit is expediently arranged in the upper region of the filler neck in such a way that the output member and preferably also the entire linear drive is mounted horizontally.
  • the linear drive is connected to the locking flaps via a swivel linkage.
  • This version has the advantage that the more sensitive linear drives are arranged in an area that is not particularly exposed to dust and dirt.
  • the filler neck is double-walled, so that an annular channel adjoins the throughflow channel, the actuating drive or the actuating drives then being arranged in this annular channel. This ring channel also serves to extract the air escaping from the filling large bag.
  • the outer wall of the filler neck is designed, at least in the lower region, as an inflatable hose which can be acted upon by compressed air. After the upper edge of the large sack has been put on, this inflation hose is then pressurized with compressed air and expanded, so that the upper edge of the sack is pressed against an abutment containing the sack buckle. To remove the filled bag, the inflation hose is vented and the bag buckle opened.
  • the filler neck is expediently pivotable about a horizontal axis is at a distance from the outflow opening of the filler neck. This allows the one to be filled A large bag is attached to the side of the filler neck and from the bottom and set using the bag buckle. So that a swiveling movement is unimpeded can be carried out, it is provided that the horizontal axis laterally stands next to the filler neck, preferably adjacent to the outer wall.
  • the Ease of use is significantly increased if the filler neck is opened using a Actuator is pivotable.
  • This actuator contains at least one piston-cylinder unit. The pivoting movement can depend on the position of the closure flaps respectively. So the filler neck could be tilted when the flaps are closed. As soon as the large sack With the bag buckle in place, the filler neck could return to normal vertical Filling position.
  • the filler neck 10 shown in Figure 1 contains a flow channel 11, the is circular in cross section.
  • the filling material is from a not shown, arranged above the filler neck 10 scales.
  • the product flow is controlled by a metering device, not shown.
  • the filler neck 10 is provided with an inner wall 12 delimiting the flow channel 11 and an outer wall 13, wherein between the inner wall 12 and the Outer wall 13 is an annular channel 14.
  • the outflow opening of the Flow channel 11 side are two about horizontal axes 15, 16th pivotable flaps 17, 18 mounted.
  • the flaps are from the open position shown in Figure 1 by means of actuating piston cylinder units 19, 20 pivotable into a closed position. This is done immediately after the end of the filling process and before removing the not shown filled sack.
  • the sack is connected fixed with the abutment 22.
  • the shutters 17, 18 are preferred pivoted into the open position after the attached to the filler neck 10 Large bag has been inflated because the flaps 17, 18 are inflating favor.
  • the flaps 17, 18 are pivoted into the closed position, after either the inflation hose 13a is depressurized or when the Bag buckle is opened. Contrary to the representation according to FIG.
  • the Actuators 19, 20 and the piston-cylinder units also in the upper area or can also be arranged above the filler neck 10. Expediently then mounted them horizontally. They are about a well known swivel linkage drive technology connected to the flaps 17, 18. The actuators 19, 20 are then as good as possible against dust and dirt pollution protected.
  • FIG. 2 shows that the filling machine or the filling nozzle 10 has an operator platform 24 is assigned so that the operator to be filled, not shown Large bag can attach to the filler neck 10.
  • a support device 26 is also provided below the filler neck 10, which can be adjusted in height, so that the large bag can be filled at any filling level can rely on it.
  • Figure 2 and Figure 4 is the filler neck 10 drawn in the position inclined against the vertical, in which the large sack is attached to it.
  • FIG. 2 in particular shows that the distance changes as a result reduced to the operator so that the attachment is easier.
  • the Figure 4 also shows that the flaps 17, 18 in the inclined position the filler neck are closed.
  • FIG. 3 shows the filler neck 10 as a detail.
  • the filling position is drawn with the flaps 17, 18 open
  • FIG. 3 also shows that the horizontal axis 25 adjoins the outer wall 13 is arranged. It is also at a distance from the outflow opening of the Filler neck 10.
  • the filler neck 10 pivoted by means of an actuator.
  • This actuator preferably contains one Piston cylinder unit in the same design as that used for opening and closing the closure flaps 17, 18 is required.
  • the invention is not restricted to the exemplary embodiments shown.
  • Essential is that preferably the outflow opening of the throughflow channel 11 is closed by a closing element 17, 18 when the filling process ends is so that detachable filling material is retained from the inner surface of the filler neck 10 becomes.
