Definitions

  • the invention relates to a device and a method for contamination-preventing decanting (emptying or filling of containers, for example bulk containers or silos or the like).
  • contamination-preventing decanting empty or filling of containers, for example bulk containers or silos or the like.
  • the products have an ever-increasing degree of specialization, which means: ever-higher degrees of purity, more and more effective and valuable substances and possibly even more dangerous substances.
  • the products to be processed are not open, but in closed transport containers such.
  • closed transport containers such as fixed transport containers, flexible transport containers (also called big bags) or barrels handled. All transport containers can additionally be equipped with a foil inner bag (inner liner).
  • attachment means any containers in which there is something which is then to be in another container or in another device.
  • the products are stored and processed in containers.
  • it may also be solids or articles coming from an insulator. Therefore, the term plant is used in the following, which also includes the term container or insulator or in the broadest sense also a room.
  • the receptacle to be refilled is hereinafter referred to as the institution.
  • the invention is therefore based on the object to provide a new method and a new device, which ensures a complete contamination avoidance.
  • This object is achieved by the method according to claim 1 or by an apparatus according to claim 5 and in particular by the novel use of a weldable and peelable continuous film tube according to claim 17.
  • claim 10 also discloses an improved method for not only contamination-free but also sterile decanting , Claim 15 a device based on this improved method.
  • the essential feature of the new device and the new method is the use of a weldable peelable Endlosschlauchfolic in conjunction with a complete replacement of the known Abbindbacters by welding, in particular at the setting site [3.1], which must not be expressly seen in accordance with the known WO-A , Firstly, it is ensured by the inventive welding at this point that any contaminating coatings of the film tube in the weld remain trapped (melted down) and can not be released to the environment. Secondly, the peelability of the endless tubular film according to the invention makes it possible, after welding to the inlet, to establish the connection between the container and the device without having to carry out any manipulations with the twine.
  • peelability is meant that property in which a - possibly with itself - strigeisste plastic film at the weld seam can be solved again, as if it had not been welded. These are specially treated or produced films that have this property. In most cases, this technique is already used on Kunitsioff packaging to make it easier for a customer to open the packaging.
  • the new devices and the new methods also result in particular in the advantage that the systems and devices are optimally closed after the inventive refilling with the endless film tube and thus require no additional closing devices, which is not only the purity of the method but also the total Improved efficiency compared to conventional systems.
  • any means known per se such as e.g. a Radialblähring be used according to the aforementioned WO-A.
  • the Blähring 9 is explicitly referenced from the figures of WO-A and the accompanying explanatory parts of the description
  • the method is set up so that it is optimally suited for the contamination-avoiding transfer of free-flowing goods, eg powders and solids.
  • free-flowing goods eg powders and solids.
  • organ transplants it is inevitable to transport organs or tissues that must be transported as sterile as possible and free of contamination and, if necessary, repacked.
  • Such tissues or organs and the like. can also be optimally filled with the erfindungezessen solutions.
  • the goods are transferred from a system with an optionally flexible outlet into a downstream device with a tube-shaped weldable inlet of an inner liner, the method having the following method steps.
  • Such systems are standard in a variety of forms (silos, transport bags, insulators, clean rooms, etc.) and need not be explained in more detail. Vessels with liners are also standard and commonly used. The inner liner is intended to discourage the material being picked up from the actual container into which it is to be transferred and thus to prevent contamination of the device and / or material.
  • an endless film tube which is weldable on its outside and inside, the inside after peeling is peelable, attached to the outlet of the plant and indeed so that it can be pulled like an extension of the outlet along its longitudinal extent.
  • the continuous film tube is e.g. fixed with a Blähring, so that it can be tightened until it is used up.
  • the endless film tube is unfolded bellows-like for this purpose. This is known per se and has the advantage that the transport and storage as well as the tracking of continuous film tube is easy.
  • the placing of the inlet of the device to be transferred to follows around the outside of the continuous film tube so that the inlet side edge of the inlet is above the welding point of the continuous film tube.
  • material is forced back out of the endless film tube in the direction of the installation, so that the inner sides of the endless film tube come to rest against one another and the inner side of the inlet on the outer side of the endless film tube.
  • the welding of the endless film tube with the inlet so that the continuous film tube between its existing weld and the inlet side edge of the inlet at least one continuous new weld is formed on the one hand the inside of the inlet to the outside of the continuous film tube and on the other hand at the same point the inside of the endless film tube connects.
  • the welding process can be carried out with conventional impulse welding devices, but also by thermal welding or by laser welding, for example by means of the transmission method.
  • the two welds are peeled inside the continuous film tube so that the system is connected to the device via a laterally closed tunnel.
  • the transfer process can take place until the continuous film tube is rewelded, preferably after prior material displacement by constriction at a third point, thus preventing the flow of material.
  • This third welding corresponds to the first and the cycle is closed or the next device can be filled.
  • the welding at the third point is carried out so broadly that subsequently in the region within the weld seam - preferably approximately in the middle, the transection of the continuous film tube takes place.
  • the welding can be carried out at the third place as a double weld with a central seam.
  • the holder of the endless film tube is preferably a tubular film carrier, optionally with a Blähring or the like. works for fixation.
  • a practical welding process results when the welding is carried out by means of pulse welding technique, and / or that before welding the endless film tube is compressed by means of clamping bars, so that the material is displaced in the region of the subsequent weld as possible up / down in the film tube.
  • the bars and welding rollers, welding electrodes or the like. are preferably integrally formed, so that the bars serve them as a guide.
  • Pulse-welding technique is preferably used according to the invention.
  • Other comparable welding technologies such as e.g. However, ultrasonic technology or laser welding technology can also be used.
  • a device according to the invention for the contamination-free transfer of pourable materials and in particular for carrying out a method specified above is specified in claim 5.
  • the welding device is a pulse welding device and / or it includes a separation device, which can preferably cut through the endless tubular film approximately in the middle of the weld. If a cut is made through the welded area, it is ensured that contaminated surfaces are not even exposed. Any contamination is and will be integrated in the weld seam.
  • polyethylene As a typical plastic for the endless tubular film is available polyethylene, from which most of the inner liners are made. However, the invention is by no means limited to polyethylene.
  • Endless tubular films have of course been known for some time, as also indicated in WO-A.
  • endless tube films with a peelable inner surface have not been used for transfer operations.
  • the welding and separation is accomplished from the outside through the transition foil, without welding or separating the transition foil itself. Since this inner layer of the transition foil is not weldable, no connection of the films.
  • the sealing film is selected from pure polyethylene, since it is so continuously weldable.
  • the manipulation is particularly simple if the pouch is tightly welded to the inlet, then sterilized, preferably Y-sterilized and supplied as an accessory to the ripper.
  • the welding on the third point of the continuous film tube can be carried out so broadly, and then in the area within the weld - preferably approximately centrally the transection of the continuous film tube done, after which a new filling / Um sympagang can be done in a new facility.
  • a double-seam seam with a central dividing seam can be attached to the continuous film tube at the third position.
  • the waste product (token) obtained as a waste product can - if it does not matter - remain in the device and be disposed of after emptying the device. However, it can also be removed through the spout.
  • the invention is not limited to those methods in which the transfer process is carried out from top to bottom. There are also included methods in which the system is retative to the device in a plane and the endless film tube is therefore arranged horizontally.
  • the bag-shaped sealing film is formed together with the loop-shaped transition foil as a bag which is firmly connected to the inlet of the inner liner and sterilized.
  • a package bag with inner liner can - even sterile packed - easily transported and mounted.
  • the endless tubular film is original or welded from the last separation down or at its one end 2a facing the end 3. The process is thereby kept closed.
  • the inlet is part of an inner liner 4a to be filled in a device (not shown).
  • the inlet 2a of the inner liner 4a must be internally weldable. It is open in this embodiment and therefore may not be sterile.
  • this structure is less used to protect the product to be filled, but rather to protect the operators from contamination.
  • 3 and 4 show the next step, in which the free welded end 3a of the endless tubular film is inserted into the inner liner 4a or its inlet 2a to be filled.
  • Fig.7 and 8 now show the process of opening the hose connection to enable the Um Glallvorgangs: the first weld 3a and the second weld 6a are peeled, ie externally detects an operator, the endless tubular film 1 and pulls them apart, wherein the internal welds 3a and 6a aufpeelen.
  • the opening or the Aufpeelen may optionally also be effected by the optionally slightly increased inerting pressure of the material from the plant.
  • Fig.9 and 10th shows the process of completing the filling process.
  • the endless tubular film 1 is preferably separated with a separating weld seam 3b.
  • a separating weld 3b is a weld which, after the welding operation, allows separation of the two parts which abut the weld. The two parts remain welded at the ends facing each other.
  • the transfer process in the plant as well as in the device is thus closed, since the cutting seam as mentioned forms an edge weld.
  • the weld seam 3b corresponds to the weld seam 3a in a new cycle.
  • FIGS. 11 and 12 shows the next step, in which preferably the inner liner 4a is closed at its upper end again by the free ends of the inlet 2a at a fourth spot 7 tightly welded.
  • the welded-off (3b ") remainder of the endless tubular film 1 is placed or inserted in the inlet 2a.
  • Fig.15 and 16 show how endless tubular films in the special inlet structure consisting of transition foil 5 and sealing foil 16 welded to the inlet as a bag. 7 trained special be inserted:
  • the endless tubular film 1 is inserted into the bag-shaped recess of the sealing film 16 of the inner liner 4b to be filled.
  • the outer sides of the sealing film 16 thus touch the outer sides of the endless film tube 1.
  • the outer side in this case is the side that comes into contact with the environment. From the perspective of the bag 7, however, it is more due to the bag formation of the sealing film 16 is an inner side.
  • the outside world always speaks in the above sense.
  • Fig.17 and 18th now show the process in which the nested endless tubular film 1 and sealing film 16 are welded: - With a welder (not shown, because in itself conventional), the endless tubular film 1 and the sealing film 16 are welded together, so that two tight welds 8a, 8b between the continuous film tube 1 and the bag 7 arise. In this process, the endless tubular film 1 is also welded together. During the welding process, a separating seam 9 is set between the welding seams 8a and 8b. This separates the non-sterile part in the form of a waste part 10. The welding and separation is done from the outside through the transition foil 5 through. Since the inner layer is not weldable, there is no connection of the inside of the transition foil 5 with the inside of the sealing foil 16 or with the endless tubular foil 1.
  • Fig.21 and 22nd show the process of peeling, in which the endless tubular film 1 and with it the sealing film 16 is opened.
  • the inner liner 4b is tightly connected to the system or its outlet.
  • the istschweisst, waste part 10 is removed in this embodiment as a waste part of the insulator (Appendix) ago.
  • the inner liner 4b is filled or emptied sterile.
  • the separating seam 3b with its edge welding would correspond to the weld seam 3a on the endless tubular film 1.
