Definitions

  • the invention relates to a device for evacuating and heat sealing packaging containing a product to be packaged, with a movable conveyor belt for the packages to be treated and treated, containing the product to be packaged, with an evacuation and sealing hood which is at least partially above the conveyor belt and at right angles Open and close to the conveyor belt level in order to pick up the packaging to be treated in the first case and to release the treated packaging in the second case.
  • Such a known device is used, for example, to pack coffee in bags in a vacuum-tight manner.
  • piece goods for example sausage and meat
  • the conveyor belt moves step by step from a loading station to the evacuation and sealing hood, and then from here to a delivery point.
  • the moving conveyor belt is loaded by hand if several packages containing packaging material are to be conveyed to the hood at the same time during one movement step of the conveyor belt. This stems from the fact that packaging machines generally always deliver packaging with the packaging goods incorporated therein, always at the same point of the loading station with respect to the conveyor belt.
  • the step-wise movement of the conveyor belt is also disadvantageous when only one single package is placed per movement step if the packaging material in the packaging contains a considerable mass and / or if the packaging with the packaging material therein contains a proportionate amount has an unstable position on the conveyor belt, for example when sausages are to be packed.
  • the inertia of the packaging material and its relatively unstable position on the conveyor belt can result in the packaging lying thereon with the packaging material changing its position on the conveyor belt when starting and stopping the conveyor belt. Then the packaging is no longer brought into the correct position within the hood.
  • the aim is to create a device with which the aforementioned disadvantages can be avoided.
  • the device according to the invention is characterized in that the conveyor belt moves continuously and that the evacuation and sealing hood can be moved parallel to the conveyor belt plane in the direction of the upper conveyor belt tower and in the opposite direction, in the first case with the hood closed and in the second case with the hood open .
  • one package after the other can now be delivered to the loading station at the same point by means of a delivery arm of the packaging machine mentioned at the beginning, in which case these packages come to lie next to one another by the constantly moving conveyor belt.
  • the distance of the packages lying one behind the other in the direction of the conveyor belt can be determined and changed by a corresponding working speed of the above-mentioned delivery arm of the packaging machine and / or by a corresponding change in the speed of the conveyor belt. It is therefore possible for the conveyor belt to be automatically and easily occupied, for example by a delivery arm of the packaging machine. But also when the conveyor belt is loaded with packaging by hand. the operator can always hand the packaging over to the conveyor belt at the same point in the loading station.
  • the dwell time of the packaging or of the packaging within the closed hood can be chosen to be longer than in the known device, in which, during the movement of the conveyor belt, the in Seen the conveying direction, the stationary hood cannot be closed.
  • the throughput capacity of the device can be increased if the hood moves relatively quickly in the opposite direction to the direction of movement of the upper conveyor belt strand.
  • the device has a frame 1, 2 and 3, in which a conveyor belt 4 is held continuously movable by means of deflection rollers 5, 6.
  • the conveyor belt 4 is held taut in the longitudinal direction by means of a tensioning device 7.
  • the conveyor belt 4 has an upper strand 8 and a lower strand 9.
  • the upper conveyor belt strand 8 moves continuously in the direction of an arrow 10, so that the loading of the conveyor belt 4 at a loading station, in the drawing to the left of the frame 1, 2, 3 he follows.
  • the delivery point for the treated packaging containing the goods to be packaged is then to the right of frame 1, 2, 3 in the drawing.
  • the device has an evacuation and sealing hood 11, which has an upper part 12 and a lower part 13.
  • the lower hood part 13 is fastened to a cylinder 16 by means of brackets 14, 15.
  • the upper hood part 12 has the devices 17 used for heat sealing and the devices 18 used for evacuation.
  • the upper hood part 12 is guided along guide columns 19, which lie congruently one behind the other in the drawing, vertically displaceable relative to the lower hood part 13.
  • the upper hood part 12 is provided with guide bushes 20.
  • the hood 11 is in its closed position with solid lines. In the open position of the hood, the hood part 12 is in the position 12 '.
  • a piston rod 21 supported on the frame 1, 2, 3 is located within the cylinder 16.
  • the lower hood part 13 forms together with its brackets 14, 15 and the cylinder 16 a carriage which can be moved along guides, not shown, fixed to the frame in the plane of the drawing sheet.
  • This unit has a piston rod 23 which lies in the horizontal path of movement of the hood 11.
  • This unit 22 has two functions, which will be explained later.
  • the drives for the movement of the conveyor belt 4 as well as for lifting and lowering the hood part 12 are not shown.
  • the opened hood 11 is moved by the unit 16, 21 in the opposite direction to the upper conveyor belt section 8 Moved back to the aforementioned starting position in the direction of an arrow 26, so that the upper hood part is again in the position 12 ' serves for the hood so that the relatively high inertial forces of the hood 11 are braked softly
  • the evacuated and sealed packages are continuously delivered to the deflection roller 6. This is also advantageous, since in this way the packagings can be processed continuously and a large number of quickly moving packagings does not gradually arise.
