Definitions

  • the invention relates to a filling machine for filling open large sacks with a filler neck, at the bottom of which the large bag to be filled can be attached is that in the lower region of the filler neck at least one closing element is arranged, which by means of a controllable actuator into a through-flow the filling nozzle releasing and closing position can be brought.
  • bulk bags are in the industry also referred to as big bags. They are made of a heavy duty material manufactured, preferably from a ribbon fabric. In the normal case will be the large bags filled with 1000 kg of a filling.
  • the dimensions of the large bags depend on the specific weight or the weight of the filling material. It is not to prevent, preferably due to a static charge, Filling material deposits on the inner surface of the filling channel. After the end of the filling process it comes during the removal and closing of the large bag to shock of the filler neck. The adhering to the inner surface of the filling channel Filled particles are then released, so that they are on the still below Sack falling.
  • the nachrieselnde contents can quite a weight of several Make out kilograms. However, there are high demands today, in particular clean bags are required.
  • the invention has for its object to make the filling machine so that the sensitive linear actuators are placed in a range that is not particularly highly charged with dust and dirt.
  • the stated object is achieved by at least the output member of the actuator horizontal mounted and guided through the annular channel pivot linkage with the closing elements drive technology is connected.
  • the filler neck is now double-walled, so that at the flow channel an annular channel connects, wherein in this annular channel of the actuator or the adjusting drives are arranged.
  • This ring channel also serves for suction the air escaping from the filling large bag.
  • actuator a pneumatically actuated piston-cylinder unit in question. Since these are at a distance from the discharge opening of the filling nozzle stand, that is, they are located in the upper part of the filling nozzle, they are as well protected as possible against dust and dirt.
  • Each closing element expediently consists of two closing flaps, the two horizontal, parallel and spaced axes are pivotable.
  • the closing element consisting of two flaps offers the advantage that in a preferred embodiment by each flap only half the outlet opening or half the cross section of the flow channel must be closed, so that the flaps still stand above the level of the contents in the opened state, if the weight of the Sackes is reached as a certain length for the closure of the filled large bag necessary is.
  • the flow channel of the filler neck is in a preferred embodiment circular. If the closure element consists of two flaps, does it make sense if they are the same or almost the same in size? and that they are therefore semicircular or approximately semicircular are.
  • each closing element means a separate actuator, preferably by means of a linear actuator, operable is.
  • the outer wall of the filler neck, at least in the lower Range is designed as a pressurizable air pressure inflatable tube. After applying the upper edge of the large bag, this inflatable tube then pressurized with air and expanded, so that the upper edge of the bag against a sack buckle containing abutment is pressed. To lose weight filled bag, the inflatable tube is vented and the bag buckle opened.
  • the filler neck is pivotable about a horizontal axis, the is at a distance to the discharge opening of the filler neck.
  • This allows the to be filled Large bag is attached laterally and from below onto the filler neck and be fixed by means of the bag buckle. So that a pivoting movement unhindered can be performed, it is provided that the horizontal axis laterally adjacent to the filler neck, preferably adjacent to the outer wall.
  • This actuator includes at least one piston-cylinder unit. The pivoting movement may be dependent on the position of the shutters respectively. So the filler neck could be driven into the oblique position when the flaps are closed. Once the big bag by means of the sack buckle is fixed, the filler neck could return to the normal vertical Filling be driven.
  • the filler neck 10 shown in Figure 1 includes a flow channel 11, the is circular in cross-section.
  • the contents are from a not shown, distributed above the filler neck 10 arranged scales.
  • the product flow is controlled by a metering device, not shown.
  • the filler neck 10 is with a flow channel 11 bounding inner wall 12th and an outer wall 13, wherein between the inner wall 12 and the Outside wall 13 an annular channel 14 is located.
  • the outflow opening of the Throughflow channels 11 associated 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 actuators forming piston-cylinder units 19, 20 pivotable into a closed position.
  • the lower portion of the outer wall 13 as inflatable tube 13 a formed after the application of the empty large bag is expanded by applying compressed air, so that the bag edge against an annular abutment 22 is pressed, which also the bag buckle 23rd contains. Due to the expansion of the inflatable tube 13a, the bag is connected determined with the abutment 22.
  • the flaps 17, 18 are preferred pivoted in the open position after the attached to the filler neck 10 Gross bag was inflated, since the flaps 17, 18, the inflation favor.
  • the flaps 17, 18 are pivoted into the closed position, after either the inflation tube 13a is depressurized or if the Sack buckle is opened.
  • FIG. 2 shows that the filling machine or filling nozzle 10 is an operator's platform 24 is assigned, so that the operator to be filled, not shown Can attach large bag to the filler neck 10.
  • the design of the filler neck 10 is a horizontal axis 25 pivotally, in particular the figure 4 shows. Below the filling nozzle 10 is still a support means 26 is provided which can be adjusted in height, so that the big bag at every degree of filling can support it.
  • Figure 2 and Figure 4 is the filler neck 10 drawn in the inclined to the vertical position in which the big bag attached to it.
  • Figure 2 shows that the distance thereby reduced to the operator, so that the attachment is facilitated.
  • the FIG. 4 also shows that the closing flaps 17, 18 are in the inclined position of the filler neck are closed.
  • FIG. 3 shows the filler neck 10 as a detail. Drawn is the filling position with open flaps 17, 18. The Figure 3 also shows that the horizontal axis 25 adjacent the outer wall 13 is arranged. In addition, it is at a distance to the outflow of the Filler neck 10. In the illustrated embodiment, it also consists of two separate sections. In a manner not shown, the filler neck 10th pivoted by means of an actuator. This actuator preferably includes a Piston-cylinder unit of the same design as that used for opening and closing the closure flaps 17, 18 is needed.
  • the invention is not limited to the illustrated embodiments.
  • Essential is that preferably the outflow opening of the flow-through 11th is closed by a closing element 17, 18 when the filling process is completed is, so that 10 retained from the inner surface of the filler neck solving becomes.
