Definitions
- the present invention relates to an apparatus and a method for opening packages, in particular the
- Opening garbage bags which are generally made of plastic or other material such as paper.
- the known device for the opening of plastic bag consists of a conveyor belt, on which the openable garbage bags are fed to tear elements at regular intervals, through which the garbage bags at least
- the device has a further tearing and spreading element for gripping the bags on the sides, in which the tearing and spreading elements so
- This device has a relatively large hopper into which the garbage bags to be opened are filled.
- the two worm rollers rotate in opposite directions to each other.
- the sacks are for the most part damaged and torn open, the contents of the sacks being at least partially removed from the sacks, so that re-sorting is recommended. After opening the yellow bags they fall onto a conveyor belt and are transported away.
- Another document G 93 09 868.5 discloses a sack-breaker for opening and emptying garbage bags or similar products that must pass through a narrow passage on a conveyor belt, wherein the geometric dimensions of the passage is smaller than that of garbage bags and thus the sacks to burst be brought so that the subsequent brush wheels continue to receive the bags and tear completely.
- Packaging such as garbage bags, characterized by at least one conveyor characterized in that the packages to be opened are supplied to at least one cavity in which acts on the outer wall of the packages at least one fine jet gas stream which damages the package and thereby opens.
- Packaging has at least one conveying means and at least one cavity, in which at least one nozzle, from which a directed gas jet emerges, is arranged, which is oriented in such a way that it acts destructively on the surface of the packaging.
- Dry ice, water or other abrasive can be amplified. It is also advantageous that the abrasive can be adjusted by a metering unit in the amount.
- a gas negative pressure (p i ⁇ p a ) prevails.
- the bundled gas jet in the cavity is aligned horizontally and / or vertically.
- gas pressure is controllable.
- At least one pressure tank is disposed at a suitable location in the immediate vicinity of the jet space.
- the content of the opened packaging is received by at least one conveyor.
- Another advantage is the fact that the gas flow emerges from the nozzles pulse-like.
- Nozzle jet is controllable.
- the cavity before insertion and after discharge has a sound attenuation.
- the at least one cavity can be built on an existing conveyor. It is also advantageous that the nozzles can have different opening times.
- At least one dedusting device is connected to the cavity.
- Figure 1 is a schematic representation of
- Figure 2 is a schematic cross-sectional view transverse to the conveying direction of the packages (2) through cavity ⁇ 4) with the nozzles ⁇ 7, 7 ') arranged therein;
- Figure 3 is a schematic side view of the cavity (4) with arranged below conveyor (3);
- Figure 4 a schematic plan view of the cavity (4).
- FIG. 1 shows a schematic representation of FIG
- the Packaging 2 in the present embodiment
- Garbage bags made of a specific material, such as plastic or paper are to be supplied by means of a conveyor 3 via at least one sound-absorbing element 16, 16 'a cavity 4, in which the packages to be opened at least temporarily.
- Hollow chamber 4 are a plurality of nozzles 7, 7 ', 7 , ''
- this bundled gas flow has a predetermined cross-section, which as a rule can be flat, round or oval.
- the nozzle 7, 7 ', 7''to a pressure tank 9 and the compressor 10 the gas are connected, from which via a controllable valve 11, 11', 11 '' in a pulsed manner to the nozzles 7, 7, 7 ''is supplied.
- Abrasive agents such as sand, ice, dry ice and water which via a metering unit 6 in front of the nozzles 7, 7 ', 7' 'by
- the hollow chamber 4 is subjected to a relatively low negative pressure (p i ⁇ p a ), whereby an intensive dust formation upon entry and exit from the cavity is largely avoided, where p i is the internal pressure and p a is the atmospheric pressure.
- a dedusting device 15 is connected, which evacuates the cavity 4 with the fan 17 via a filter 18.
- both the opened sacks and the contents of the opened sacks are fed to a conveying means, which further distributes the material to be further sorted
- the 2 shows a schematic cross-sectional view of the cavity transversely to the conveying direction of the conveyor 3.
- the at least one cavity 4 is equipped with a plurality of nozzles and equipped.
- the number of gas nozzles 7, 7 ', 7 "essentially depends on the size of the cavity 4, through which the packages 2 to be opened are guided. Further, the number of nozzles 7, 7 ', 7 , ''depends on the material of the packages to be damaged and on the
- Conveyor 3 are supplied to the cavity 4. Furthermore, the direction of the gas jets is not necessarily perpendicular to each other, but may be any adjustable one
- the gas to be used flows continuously out of the nozzles 7, 7 ', 7 "at high pressure, the gas jet thus
- the direction of the gas jet 8, 8 'of a single nozzle does not have to be constant in one direction, but can be moved back and forth, which can be effected by a hinge 13, 13' on the nozzle 7.
- the gas jets 8, 8 ', 8 may also be pulsed the nozzles 7, 7 ', 7 , ''exit, ' whereby the tearing effect on the packaging 2 is increased.
- Gas jet takes place through a controllable valve 11, 11 ', 11' ', which is arranged between a composite line 14 and the pressure tank 9.
- FIG. 3 shows a schematic side view of the
- the packages to be opened enter into the cavity 4 and are guided past the nozzles 7, 7 'by the conveying means 3. While driving through the
- Packaging of the cavity 4 the surface of the openable packaging 2 at least once by a
- Gas jet 8, 8 ', 8' ' taken so that due to ripping effect of the gas jet, the package is torn and the contents of the package is swirled around each other and distributed homogeneously on the conveyor 3.
- a pressure tank 9 is arranged, from which the gas is removed.
- Cavity 4 and the conveyor 3, on which the packages 2 to be opened are supplied to the cavity 4.
- sound damping elements 16 which at least reduce both the sound and the gas pressure exiting the cavity.
