Definitions

  • the invention relates to a method for dispensing, preferably mechanically, a container from a bag, the bag being cut open with at least one cut and the container being dispensed via an opening formed by the cut.
  • Protected rooms for example clean rooms such as isolators or RABS (Restricted Access Barrier System), are used in industry, for example, to produce pharmaceutical products in a sterile or germ-free manner.
  • product components such as containers must be transferred sterile or germ-free to the section of a protected room in which the product components are processed for manufacturing.
  • Containers are usually packed in sterile bags before use.
  • the containers in the bags must be removed from the bags to complete a product.
  • bags are placed in devices and gripped for opening.
  • the bags are then cut below the area where the bag is gripped.
  • the disadvantage of this is that the opening formed by the cut is not closed or sealed, so that there is a risk that cutting waste or other contamination can get into the interior of the standing bag and contaminate the container.
  • bags can be placed on a support and opened by punching or cutting.
  • the end surfaces of the bags are usually flattened manually by a worker spread out, which is time-consuming and results in an increased risk of contamination.
  • the worker is also at increased risk of injury because he is in the vicinity of the punching and/or cutting device.
  • the invention further relates to a cutting device for a bag containing a container, with a knife for cutting the bag.
  • Knits are usually used whose blades are sharpened on one side. Razor blade-like knife blades are often used.
  • the disadvantage is that the knife blades from the prior art have to be replaced frequently, which means that the likelihood of a worker getting injured is relatively high.
  • the cutting edge of such knife blades is often shorter than the distance to be cut on the bag, so that wear requires the knife blades to be replaced particularly frequently.
  • the invention further relates to a removal device for removing a container from a bag containing the container.
  • a cut bag can be held on its top and/or bottom by a holding means and that the opening of the bag formed by the cut is opened further in particular by the holding means, so that the container is removed by the action of at least one conveying means is applied to the bag.
  • the disadvantage of the prior art is that the bag is held between the opening formed by the cut and the container, which means that a prior adjustment of the container within the bag is necessary, which can also slow down the process.
  • the invention further relates to an unpacking device.
  • a disk-shaped knife blade cooperates with a counter-element for cutting the bag, in particular rolling on the counter-element.
  • the knife blade can preferably be guided through the counter element and/or the knife blade and the counter element can mutually exert pressure on one another. Through such interaction between the knife blade and the counter element, the bag can be cut particularly accurately and cleanly.
  • the knife blade can preferably be round or oval, with the cutting edge of the knife blade preferably extending over the entire circumference of the disc-shaped knife blade.
  • the method according to the invention can be implemented in a particularly efficient and resource-saving manner, since the knife blade is subjected to less stress. This means that frequent replacement of the knife blade is not necessary, which can protect workers in particular from injuries. It turns out that one...
  • a rolling knife blade a cutting section changes automatically during the cutting process, while with a rigid knife blade the same section always cuts. This means that the rolling knife blade becomes dull less quickly and needs to be replaced less often.
  • shear stress on the material to be cut can be reduced during the cutting process. This means that more precise cuts can be made and wear on the knife blade can be reduced.
  • the knife blade and/or the counter element are driven by a motor.
  • Motor-driven knife blades and/or counter elements are particularly advantageous if manual work is to be avoided, for example in protected rooms. This means that workers can also be advantageously protected from cuts.
  • a cut can be carried out even more cleanly using a motor-driven knife blade and/or a motor-driven counter element, so that even less abrasion and/or contamination can occur at the opening formed by the cut.
  • a container can advantageously be removed from the bag in a particularly contamination-free manner.
  • the knife blade can be arranged to rotate freely on a motor-driven carriage, for example. This means that the knife blade can rest on a counter element itself, for example, can be arranged stationary or rotating. This has the advantage that different areas of the knife blade come into contact during cutting, so that the knife blade becomes dull less quickly.
  • the knife blade and/or the counter element is/are mechanically coupled to an actuator that can be manually operated from the outside.
  • a method can therefore also be carried out using a manually operated actuator. It is therefore advantageously possible for a cutting process to be controlled from the outside by a worker, so that both a protected space and the worker can be protected.
  • a protected space can be characterized by the fact that a (e.g. liquid or gaseous) substance, an object, an interaction (e.g. electromagnetic and/or radioactive and/or high-energy radiation) and/or a person can pass through a boundary of the room, for example from the inside and/or from the outside, can be controlled, in particular preventable.
  • a e.g. liquid or gaseous
  • an interaction e.g. electromagnetic and/or radioactive and/or high-energy radiation
  • a person can pass through a boundary of the room, for example from the inside and/or from the outside, can be controlled, in particular preventable.
  • the counter element is a roller. This means that particularly little abrasion can advantageously be produced by a cutting process, since both the disc-shaped knife blade and the counter element can carry out a rotational movement during which the bag is cut. This means the knife blade can stay sharp longer. Another advantage of unrolling is that the cutting process cuts different areas or sections of the knife blade, allowing wear to be evenly distributed across the entire knife blade.
  • the counter element is a straight running surface. This means that the knife blade can advantageously be guided on the running surface, which means that a cut can also take place in a targeted area of the bag.
  • the counter element is a scissor blade.
  • the bag can be cut from two sides, i.e. by the knife blade and the scissor blade. Cutting on both sides can ensure that the cut can be carried out even cleaner. This also ensures that if the knife blade is blunt or partially blunt, a bag can still be cut.
  • the bag is gripped with a gripping device on which a knife is moved to cut the bag.
  • the bag can therefore advantageously be held by the gripping device during cutting. Since a knife is moved on the gripping device to cut the bag, space and material can be saved, since the bag can be held and cut by or on the gripping device.
  • the bag is held below the cut, in particular that the opening remains closed after the cut, in particular for microorganisms and/or particles. Holding the bag below the cut ensures that the bag does not fall after cutting. By closing the opening after the cut has been made, cutting waste and/or other contamination can be prevented from getting into the inside of the bag.
  • the bag hangs on a bag carrier during the cut.
  • the bag carrier can be attached to a gripping device, in particular a gripping device as described above or claimed below, so that the bag can advantageously be gripped, held and opened by a device.
  • a bag hanging on a bag carrier no longer needs to be positioned correctly before cutting, especially if, as previously described or claimed below, the bag is held below the cut. This means that cutting the bag and discharging the bag can be carried out particularly effectively.
  • a knife carriage is magnetically coupled to a drive device and is moved by it.
  • a knife carriage i.e. a movable component which has at least one knife, can therefore be magnetically coupled to a drive device and moved by it. Thanks to the magnetic coupling, the knife carriage can be moved almost smoothly, so that very little or no abrasion occurs during the movement of the knife carriage. This is particularly advantageous if the procedure is carried out in a protected room.
  • the knife carriage can be used to be moved on a gripping device, in particular the gripping device already mentioned.
  • a container can be dispensed from a bag even more efficiently.
  • the bag is held at a height of the container with at least one releasable holding means, while a conveying means pushes the container out of the bag. This means that the container can simply be pushed out of the bag without the bag moving. After the container has been removed, the holding means can detach from the empty bag so that the bag can be disposed of.
  • the releasable holding means can in particular be designed as a suction gripper, whereby the release of the holding means from the bag can be carried out relatively easily, especially after the container has been removed.
  • the holding means lift a top side of the bag while it is being pushed.
  • the container can thus be pushed out of the bag without touching an inner wall of the bag and/or the cut edge at the opening of the bag. This means that contamination of the container at the opening, particularly during dispensing, can be prevented.
  • the underside of the bag lies unfixed on a support while it is being pushed.
  • Unfixed means in particular that the bag lies at least partially freely movable on the support.
  • the bag can also lie completely freely on the support. Because the bag lies unfixed on the support, the container can be easily pushed out of the bag, especially if the bag is held on a cover side by an adhesive, in particular the one mentioned above.
  • the bag is preferably blown from the front before and/or during pushing.
  • the bag can be blown with preferably filtered air and/or another preferably filtered gas, preferably from an adjacent chamber.
  • the volume within the bag can thus increase, as a result of which a distance between the container and, in particular, a top side of the bag can be increased. This allows the container to be better protected from contamination during delivery, particularly at the opening formed by the cut.
  • the blowing can be effected, for example, with a lance that is guided inside through the opening and/or outside the bag in front of the opening. For example, this can be done through an access opening of an isolator or RABS downstream in a processing path.
  • the conveying means stops before the container leaves the bag, i.e. before it is completely outside the bag, for example. This can advantageously prevent the container from leaving the bag at an unwanted time.
  • the container is picked up for further processing by a transport unit, in particular as claimed below.
  • stopping the conveyor and the associated stopping of the container the transfer of the container into the aforementioned transport device can be synchronized.
  • stopping the funding can prevent that the funding passes through a portal of a wall, for example violating a zone between two protected rooms. This can ensure that no contamination, for example on the conveyor, is transferred to the transport unit.
  • the conveying means pushes the container onto a container holder of a transport unit. This means that the container can be transported directly from the bag.
  • the conveying means pushes at least until a center of gravity of the container is above the container receptacle.
  • the container can be optimally pushed onto the container holder of the transport unit without the need for another device, which, for example, pulls the container onto the container holder.
  • the transport unit is magnetically coupled to a stationary coil arrangement. It is therefore advantageously possible for the transport unit to be able to move magnetically in a space, whereby in particular abrasion can be reduced during the removal and transfer of the container from the bag into the container receptacle.
  • the transport unit is moved in a suspended manner in an electromagnetic field. This means that abrasion can be prevented even more.
  • preferably pivotable centering means Before pushing, align the container in the bag transversely to a sliding direction, preferably towards the container receptacle.
  • the preferably pivotable centering means allows the container to be aligned before being pushed. This can ensure that the container is correctly pushed onto the container holder when it exits the opening of the bag. The transfer of the container to a transport unit, in particular the one already mentioned, can thus be carried out optimally.
  • an emptied bag is pushed through a disposal opening in a support for filled bags.
  • the bag can therefore be disposed of directly after the container has emerged from the opening, for example in a closable opening on or on the support.
  • another filled bag can be placed directly on the support and the container inside can be removed. This means that several bags can be processed in a relatively short period of time, which can reduce overall process time.
  • the conveying means acts on the bag on its underside from the outside with at least one roller, which pushes the container out of the bag.
  • a rotational movement of the at least one roller can thus be used to act on the container from the underside of the bag and to push it out of the bag.
  • the conveying means can apply at least one sliding block to the bag on its top side from the outside, which pushes the container out of the bag. This means that a container can be pushed out of the bag particularly efficiently.
  • the cut bag is held closed until the holding means engages.
  • the cut bag can be held closed, for example, by a gripping device, in particular the one already mentioned. This reduces the time in which contamination can pass through the opening formed by the cut.
  • the fluid flow can advantageously prevent contamination, for example contamination located on an outside of the bag, from reaching downstream sections during pushing. This makes it possible, for example, to prevent contamination, in particular the previously mentioned contamination, from reaching the transport unit during the expulsion of a container onto a transport unit. This means increased process and/or product safety can be guaranteed.
  • a preferred application of the method described and/or claimed is in a protected room and/or with a bag with sterile contents.
  • a protected space can, for example, be characterized as an area with a boundary, whereby an exchange of substances across the boundary can be controlled, in particular can be prevented. This means that defined environmental conditions can be created inside the boundary and/or unwanted or dangerous escapes of substances can be prevented.
  • the invention enables the largely automatic removal of a sterile bag contents, for example the container described, from the bag, so that the need for human intervention can be reduced.
  • Examples of a protected space include an isolator or a restricted access barrier system (RABS).
  • a knife blade is disc-shaped and interacts on a counter-element, in particular rolls on the counter-element.
  • Such a cutting device can be used in particular to carry out a previously described and/or subsequently claimed method.
  • a knife blade that is disc-shaped can be advantageous in that the knife blade wears more slowly.
  • the cutting edge of the knife blade which is preferably round or oval, can be made larger than the cutting surface of the bag to be cut.
  • the wear of the knife blade can be particularly greatly reduced. This eliminates the need to change the knife blade frequently, reducing human intervention, especially in a protected space. Also The wear occurs very evenly, which allows for a longer replacement interval (a straight blade, for example, always has the same wear point).
  • the counter element is a roller. This means that particularly little abrasion can advantageously be produced by a cutting process, since both the disc-shaped knife blade and the counter element can carry out a rotational movement during which the bag is cut. This means the knife blade can stay sharp longer.
  • the counter element is a straight running surface. This means that the knife blade can advantageously be guided on the running surface, which means that a cut can also take place in a targeted area of the bag.
  • the counter element is a scissor blade.
  • the bag can be cut from two sides, i.e. by the knife blade and the scissor blade. Cutting on both sides can ensure that the cut can be carried out even cleaner. This also ensures that if the knife blade is blunt or partially blunt, a bag can still be cut.
  • the knife blade is coupled to a drive roller which is designed to roll on a part of the bag. This allows the knife blade to advantageously carry out a rotational movement. This means that the entire circumference of the disc-shaped knife blade can be used to cut a bag.
  • the knife is movably arranged on a gripping device for the bags. The bag can thus be advantageously gripped by the gripping device and cut or opened by the movable knife.
  • the gripping device has at least one gripping finger on which the knife can be movably arranged.
