Definitions

  • the invention relates to a method for emptying hoses filled with pasty masses and to a device for carrying out this method.
  • Pasty masses such as Sealants are often used in containers such as Drums transported for processing.
  • these barrels have the major disadvantage that they can usually not be emptied in such a way that no residues of the compositions originally contained therein remain, which leads to undesirable residual contamination. This effect occurs in particular when the pasty masses are very viscous materials.
  • practice shows that e.g. in the case of pressure sensitive adhesives, the same container can only be filled two to three times. Afterwards, the contamination of the barrel has a negative effect on the product properties. The result is that the containers used are either cleaned with great effort or must be disposed of. This leads to a considerable volume of waste and high costs.
  • Tubular casings represent an alternative to the transport of pasty masses.
  • the best known is this form of transportation and sales from the field of sausage casings.
  • DE-U 29 518 071 a device for portion-wise filling of pasty contents, in particular for filling tubular casings with sausage meat, is known, which is used to convey the Filling, ie the sausage meat has a rotary valve driven in a housing as the conveying member.
  • DE-A 43 35 577 discloses a method and an apparatus for producing, filling and closing bags from an endless plastic film web.
  • DE-A 44 12 697 describes a method and a device for controlling the filling process when filling packaging sleeves, the filling device being switched off by a pulse generator in contact with the packaging sleeve when the packaging sleeve is missing.
  • This object is achieved by a method for emptying hoses filled with pasty masses, comprising the steps that a hose with a pasty mass is clamped into a device comprising a tubular device, the hose is felt through the tubular device with the longitudinal opening of the tubular casing and the opened tubular casing is separated from the pasty mass and the pasty mass leaves the device via a discharge opening.
  • a device for carrying out this method comprising a tubular device with at least three openings, namely with at least one receiving opening for receiving filled hoses, at least one discharge opening and at least one further opening, with between the at least one a receiving opening and the at least one further opening one or more slitting devices are attached.
  • the further opening of the tubular device is to be understood as an opening which is offset in its position with respect to the — not necessarily straight — connecting line between the centers of the two other openings outwards or laterally. This opening therefore does not necessarily point to the side, but can also, starting from the tubular device, point up or down, that is to say in any spatial directions, as will be explained in more detail below (see FIG. 1); however, this further opening is also referred to below as the "lateral opening”.
  • a tubular device is used to hold the hoses, the diameter of which is dimensioned such that it is at least as large as that of the filled hose to be accommodated.
  • the ratio of the diameter to the length of the tubular device should be dimensioned such that the pressure which builds up when the hose is emptied can be reduced over the length of the tube.
  • the diameter and length of the tubular device should be dimensioned in such a way that a backflow of mass in the hose is prevented. It is impossible to give the exact numerical values for this in absolute units of measure, since this also depends on the type of pasty mass in the tubes. In addition, these values also depend in detail on the design of the device used for the method according to the invention.
  • the value for the minimum or maximum diameter will be different than if the tube or the tubular device is arranged obliquely or even because it is easier to fill.
  • the respective values for the desired diameters can easily be determined by a person skilled in the art - possibly by means of a few trial trials.
  • the hose is opened by a slitting device, in particular a blade-like, mandrel-like or cutting-roll-like device, which is attached between the receiving opening and the further or lateral opening of the tube.
  • a slitting device in particular a blade-like, mandrel-like or cutting-roll-like device
  • two slitting devices that face each other can also be attached.
  • the tube cover is split in half when opened. These can then also have two opposing ones Openings of the device are removed as flat films or foils.
  • Such an embodiment is preferred insofar as the emptying of the hoses is less prone to failure in problematic cases.
  • the tubular casing itself is separated from the pasty mass in the tubular device at the at least one further opening.
  • an ejection device and / or at least one peeling device can be present in the further opening.
  • the ejection device supports the separation of the pasty mass from the tubular casing, which is open on the longitudinal side.
  • a peeling device which is located at the further opening, is preferably used for this purpose.
  • the peeling device can be a possibly adjustable separate device such as a peeling blade.
  • the peeling device can also be the corresponding structurally modified edge of the further opening. If possible because of the consistency of the pasty mass, the further opening can in a preferred case be a slit.
  • the slot makes it easier that the opened tubular casing can already leave the tubular device as a flat film. If the tubular casing is passed over the ejection device and through the further opening, for example through a slit, when the pasty mass is separated off, a flat film is obtained which can then be wound up for easier disposal.
  • the take-up reel then contains the hose in compressed form, which can be easily disposed of due to the reduced volume.
  • a part of the tubular device in the area between the slitting device and the peeling device can also comprise a jacket-heated tube or housing. This enables a temperature control of the pasty mass and thus, for example, the influencing of its consistency, such as about toughness. In this way, control of the method is also possible to a certain extent.
  • the blade itself can also be heated for this purpose.
  • the filled hose [shown here as a coiled spiral (E)] is first passed through a tube (A).
  • a tube (A) Shortly before the discharge opening or emptying point (B), which in this example is in the form of a housing or tube open at the bottom, a mandrel or a knife is inserted into the guide tube (A) from below. With the help of this dome, the tube that is pulled over it is slit lengthways.
  • the tube (A) has the task of preventing a product backflow in the direction of the hose spiral (E). This is done by dimensioning the tube (A) in such a way that it runs relatively closely around the tube, but still leaves enough clearance so that the tube can be pulled through without too much resistance. Furthermore, the length of the tube (A) must be dimensioned such that the pressure built up by the emptying cannot relax in a relaxation at the end of the tube, which would be accompanied by an expansion or bursting of the hose. Rather, the pressure must decrease over the length of the pipe.
  • the tubular film is guided around a deflection roller (C) in such a way that it can be wound up on a second roller (D).
  • a deflection roller C

Abstract

Selon ce procédé pour vider des tuyaux remplis de masses pâteuses, on serre un tuyau rempli d'une masse pâteuse (E) dans un dispositif qui comprend un organe tubulaire (A), on fait passer le tuyau à travers l'organe tubulaire de façon à ouvrir la gaine du tuyau dans le sens longitudinal, on sépare la gaine ouverte de la masse pâteuse et on expulse la masse pâteuse du dispositif à travers un orifice de décharge. Le dispositif utilisé pour mettre en oeuvre ce procédé comprend un organe tubulaire (A) avec au moins trois orifices, dont au moins un orifice d'admission de tuyaux remplis, au moins un orifice de décharge et au moins un autre orifice. Un ou plusieurs dispositifs tranchants (F) sont montés entre le ou les orifices d'admission et le ou les orifices additionnels.
