It is thereby provided a "suction bag precursor", from which (successively) can produce a large amount of bags of suction material. The hose or hoses provide the suction bag walls. In particular, only a single suction bag is used in the operation of the suction device.

In particular, the hose or tubes has an air-tight wall or filter medium wall. In an airtight wall, suction material and areas of the suction device acted upon by suction material can be airtightly covered or enclosed. In a filter medium wall, this forms a filter which is impermeable to suction material (but for example, is permeable to air). The filter medium can be adapted to the expected suction material.

In particular, the holder holds a suction bag in the interior of the suction container. As a result, the suction container can effectively serve as a protective wall for the bag. This results in a simple compact design of the corresponding suction device. Furthermore, a pressure equalization space can be provided in a simple manner in the suction material container in order to prevent suction of a suction material bag (in particular with an air-impermeable wall).

In particular, when arranged on the suction container suction head, the storage chamber is positioned in the suction material container. This results in a compact construction of the suction device. Furthermore, the risk of damage to a bag is minimized.

It is advantageous if the holder has an annular region on which the reservoir is arranged, wherein the annular region closed (ie completely) surrounds at least one continuous annular opening which is in fluidly effective connection with a suction port, even if a suction bag is held on the holder , Through the ring opening of the ring area through suction material can be coupled into a suction bag, which is held on the holder.

In a simple manner, a region of the suction device which is acted upon by suction material can be covered or enclosed airtight by a suction bag held on the holder.

It is advantageous if the reservoir has an annular cross section, wherein the annular cross section may correspond to that of a circular ring or may have a different shape than that of a circular ring. As a result, a suction bag can be produced in a simple manner, with which suction material-leading regions of the suction device can be enclosed, wherein the suction bag can be filled with suction material.

It is particularly advantageous if the storage chamber has a continuous recess, which is in communication with a storage space and through which a hose region can be carried out. A suction bag, which is held on the holder, can be produced over the hose region that has been made. This bag is in connection with the hose in the storage room. As a result, for example, an airtight enclosure of suction material-leading regions of the suction device can be realized.

It is advantageous if the storage chamber is closed except for the continuous recess, in order to minimize in particular a suction material loading of the storage space.

It is also advantageous if the continuous recess annularly and in particular closed surrounds a continuous annular opening of the holder. This results in the advantages described above. The ring shape may correspond to that of a circular ring or the ring shape may also have a different shape than that of a circular ring.

It is advantageous if the continuous recess is assigned a sealing device for sealing against the ingress of suction material into the storage space. This reduces the risk of contamination.

In one embodiment, the sealing device comprises one or more sealing elements which are arranged on the continuous recess and / or a positioning device is provided, by which one or more boundary walls of the continuous recess can be positioned (directly or indirectly) on a continuous hose region on the continuous recess are.

If a sealing element is arranged on the through-cut recess, then this can act on a hose section that has been made and contact it, in particular by pressing or without pressing, in order to achieve a seal with a boundary wall of the through-cut recess. In a positioning device, a boundary wall of the continuous recess is positioned so that the corresponding gap, which forms the continuous recess, is reduced and, in particular, the boundary wall bears directly or indirectly (via an intermediate seal) against the hose region.

It is advantageous if, in a suction operation with a suction bag, this is held by the holder in the suction material container outside the storage space and is connected to a hose in the storage space. There are suction bag from the hose, which is a supply of bag for suction and is positioned in the storage room prepared. It can thus be achieved in a simple manner, a cover of suction-leading portions of the suction device.

In particular, the held suction bag on an interior, which can be filled with suction material, and has an outer side, which faces a suction material container wall. An inside of the suction bag, which adjoins the interior, forms a dirty side of the suction bag. The outside forms a clean side of the suction bag.

It is advantageous if the holder is fixed to the suction head at least with a partial region. If the suction head is removed from the suction material container, then the holder including it attached suction bag is taken. The holder and the suction bag held thereon cover to the outside with suction material acted upon areas of the suction head (and the holder).

In one embodiment, the holder has a first part and a second part, wherein the first part and the second part (fluid-tight) are releasably connectable to each other and a portion of the first part and a portion of the second part form chamber walls for the storage space. By removing the second part of the first part can be used in a simple way, a new tube in the pantry.

It is advantageous if the first part is fixed to the suction head and the second part is releasably connected to the first part, wherein on the second part or between the first part and the second part a continuous recess for the passage of a hose portion is formed. The holder effectively forms an intermediate ring on the suction device for holding a suction bag and for receiving a suction bag precursor, namely a hose. In this embodiment, then this intermediate element (which is in particular designed as a ring) is formed in two parts with the first part and the second part.

It is particularly advantageous if a pressure compensation chamber is provided which is formed when the suction bag is held on the holder between the suction bag and a suction material container wall, and which is pressure-effectively connected to the suction fan device and is in particular pressure-effectively connected to the suction fan device via a suction chamber which can be charged with suction material , In an air-impermeable formation of a suction bag, the pressure compensation chamber prevents suction of the suction bag by the Sauggebläseeinrichtung.

It is advantageous if the pressure equalization chamber is assigned a blocking device against the ingress of suction material into the pressure compensation chamber. The pressure equalization chamber can thus be connected to the suction fan device in a simple manner in a pressure-effective manner, whereby the ingress of suction material is prevented. In particular, the locking device can then be arranged on the holder.

In one embodiment, the barrier device comprises or is a filter device which is arranged at a connection opening between an intake space (for suction material) and the pressure compensation chamber. The filter device prevents suction material from entering the pressure equalization chamber from the suction space. The filter device is in particular arranged so that a tool is necessary for their removal and thereby unintentional removal is prevented.

In an alternative or combinatorial embodiment, the blocking device is or comprises a movable closing element which is arranged in a connecting opening between an intake space and the pressure compensation space. The closing element forms a kind of check valve or backflow flap.

In particular, the movable closure element is then arranged and designed so that it is open in a suction operation with a negative pressure and is closed in a non-suction operation. In a suction operation with negative pressure, penetration of suction material from the suction space into the pressure equalization space is substantially prevented by the pressure conditions. As soon as there is a pressure equalization and especially at the transition to non-suction operation, the closing element closes.

It is advantageous if the locking device is arranged on the holder. This results in a simple structural design.

If a suction bag is held on the holder, then it covers a region of the suction device which can be acted upon by suction material, this region in particular comprising a suction connection opening, an intake space and a filter device for the suction blower device. This allows suction material to be taken up in a bag and "packaged" and removed without an operator coming in contact with suction material.

It is advantageous if a closure device is provided for closing a hose to form a suction material container and for closing a suction material bag. The closing device ensures airtight sealing. For example, the closure is made by pinching, for example, with a metal clip or with a band.

It is also advantageous if a separating device for separating a sealed bag of suction bag from a hose or other bag. This makes it possible, on the one hand, to provide a new empty suction bag, and on the other hand, a filled suction bag can be removed from the system.

The closing device or the separating device may for example be arranged fixedly on the suction device or may be associated with it in a coupled or uncoupled manner.

It is basically possible for the holder to be involved in the manufacture of the suction device.

It is also possible that a suction bag holding device for a suction device is provided, wherein the suction device comprises a suction head with a suction fan and a suction container, and the suction bag holding device comprises a holder, which is designed for fixing with the suction head, and the holder a storage chamber having a storage space, which is designed to receive one or more tubes, and wherein from a tube suction bag can be produced.

Such a suction bag holding device can be used to retrofit an existing suction device, and it is thus possible to provide a suction device which enables a comfortable and low-contamination disposal of suction material.

In particular, at least one hose is arranged in the storage space, which is in particular folded, wherein preferably the one or more hoses have an air-tight wall or wall of filter medium.

Advantageously, the holder has an annular region, on which the reservoir is arranged, wherein the annular region closed surrounds at least one continuous annular opening.

Advantageously, the storage space has an annular cross-section.

Furthermore, it is advantageous if the storage chamber has a continuous recess which is in communication with the storage space and through which a hose region can be carried out, wherein advantageously the storage chamber is closed except for the continuous recess.

Conveniently, the continuous recess is annular and in particular surrounds closed a continuous annular opening of the holder.

It is also advantageous if the continuous recess is associated with a sealing device for sealing against the ingress of suction material into the storage space.

It is also advantageous if the holder has a first part and a second part, wherein the first part and the second part are detachably connectable to each other and form a portion of the first part and a portion of the second part walls for the storage space.

It is also advantageous if in the holder a locking device is arranged against the ingress of suction material in a pressure compensation chamber.

According to the invention, a method is provided for operating a suction device according to the invention, in which a hose region is pulled out of the reservoir for producing a suction bag and the hose region is closed in the region of a lower end with a first closure.

The closing with the first closure takes place in such a way that the suction bag is "suction-dense" on the closure and in particular is airtight.

The extraction of the hose portion from the storage space takes place when the suction head is removed from the suction material container.

In the solution according to the invention, suction bags are produced in succession from an endless tube. In a suction operation of the suction device, preferably only one suction bag is used, which is held on the holder and is connected to the hose in the storage space.

It is favorable if a filled suction bag, which is held on the holder, is closed with a second closure, wherein the first closure and the second closure are spaced. The suction material is then in a "suction-tight" closed space between the first closure and the second closure.

The filled and closed with the second closure suction bag is then separated by a cutting operation of the next bag bag, which is closed with a first corresponding closure, between the first closure of the next bag and the second suction bag. This allows the filled and closed "old" bag to be removed from the system. Furthermore, a new suction bag is made, which is open on one side and can be filled from there with suction material. These operations can be carried out by an operator without contact with suction; First, the old suction bag and then the new bag of suction bags cover suction-leading areas of the suction device.

It is advantageous if the storage chamber is filled with a new tube, that even a hose portion of a preceding tube is held by the holder. This allows a new tube to be used (as a "source" of new sac bags), minimizing the risk of contamination.

In particular, the held hose region is provided with a closure or has previously been provided with a closure in order to provide a hose end suction bag which covers suction material applied areas. This hose end bag then protects against contamination.

The suction head is positioned with a first part of the holder fixed thereto so that the holder can be accessed and a second part of the holder can be removed from the first part. For example, the suction head is turned upside down (with a top on a pad). By removing the second part of the holder from the first part is accessible to the pantry. The end-of-hose bag covers suction material-leading areas.

It is then also advantageous if a new tube is placed in the reservoir over a remaining hose portion of a hose end suction bag and the second part is connected to the first part. It is then made a suction bag by appropriate closure of the new tube.

It can then be brought into the new bag after the production of a new bag of suction bag from the new hose end of the bag. The new bag now covers the dirt-carrying areas and the remaining "old" bag, d. H. the end of the hose can be detached from the holder.

The hose 48 is an endless tube, which in particular folded in the pantry 44 sitting. A corresponding hose wall is impermeable to air or formed by a filter medium impermeable to suction material. This is with appropriate closure 88 the suction bag 50 sauggutundurchlässig.

In suction operation, a pressure equalization takes place in the pressure equalization chamber 100 in that this pressure-effective with the Sauggebläseeinrichtung 22 connected is. This will "suck in" the bag 50 , in particular in an air-tight wall, by the Sauggebläseeinrichtung 22 avoided.

After completion of the cleaning operation is to remove the suction bag 50 the suction head 12 from the suction container 14 decreased, for example completely ( 9 ) or by unfolding.

The holder 38 is on the suction head 40 fixed. He is thereby mitabgenommen.

With suction material acted upon areas are outward through the bag 50 and the holder 38 covered.

For example, by lifting the suction head 12 in one direction 112 from the suction container 14 away increases the bag of suction bag 50 by appropriate extraction of further hose areas from the storage room 44 or an operator may, if necessary, by appropriate pulling on the bag 50 in the opposite direction to the direction 112 Hose areas from the storage room 44 pull to the bag 50 in a direction along the direction 112 to extend.

The vacuum bag 50 is in this condition still on an airtight wall with the hose 48 in the pantry 44 connected.

The closure 88 through which the suction bag 50 is closed at the bottom, forms a first closure.

An operator then closes off at a distance from the first closure 88 the suction bag 50 with a second closure 114 ( 9 and 10 ).

The filled vacuum bag 50 , which was made of a tube, is characterized up close and down suction-tight and in particular hermetically sealed (with appropriate design of the second closure 114 ).

An operator then closes the tubing above the one with the first closure 88 and the second closure 114 closed suction bag 50 with a lock 116 ( 9 and 10 ). This closure 116 is the first closure of a new suction bag 118 ,

After carrying out this process, the appropriately filled bag will be filled 50 from the hose 48 separated. There is a cutting movement between the second closure 114 and the first closure 116 , This is in 11 through a knife 120 indicated. The knife 120 belongs to the separation device 108 ,

It can then be the "old" filled bag 50 which is closed, removed and disposed of.

The "new" vacuum bag 118 is now over the clasp 116 sealed as a first closure in the region of its lower end, closed by a suction-tight seal. He is basically positioned as by 1 described. He can according to the interior 20 be brought to the suction tank and the suction head 12 can again on the suction material container 14 be fixed. The suction device 10 is now ready for new sucking up to the bag 118 is refilled.

During a "bag change operation", an operator does not come into contact with suction material. First, the old vacuum bag covers 50 and then the new bag 118 Suction bag acted upon areas of the suction device 10 towards the operator.

The solution according to the invention also makes it possible to prepare dusts which are hazardous to health (for example those in the classes L, M or H according to the Standard DIN EN 60335-2-69 ) Dispose of in a comfortable and dust-free manner. The operator comes with the disposal not in contact with any health-hazardous waste.

The vacuum bag 50 respectively. 118 closes with suction material acted upon components and the suction material 36 completely. The suction material is above the bag 50 respectively. 118 airtight to an outside space outside of the corresponding suction bag 50 respectively. 118 locked in. Even with a Säuggutbeutelwechsel this inclusion is retained, as the bag for suction material 118 on the hose 48 , on the previously the bag 50 was prepared again.

The pressure compensation room 100 ensures that the suction function is not impaired.

This results in a simple positioning for the corresponding bag.

The pantry 42 with the pantry 44 is in the sump tank 14 (in its interior 20 ). There is no actual Säuggutbeutelwechsel by a new bag suction bag must be positioned, but from the same hose several bags are made.

Suction-tight sealing of suction bags on the first closure 88 and the second closure 114 can be achieved for example via a type of wire clamp pliers with clamping function, for example, a pair of scissors or the like can be integrated. It is also possible, the separator 108 in the closing device 110 to integrate.

It is basically possible to use the holder 38 with the appropriate functionality in the manufacture of the suction device 10 provided.

But it is also possible that an existing suction device 10 is subsequently equipped with a corresponding Saugbeutelhaltevorrichtung which the corresponding holder 38 having the above-described construction and the described functionalities.

This holder is then designed so that it can be fixed to a corresponding suction head of the suction device and it is adapted to the geometric conditions.

Another embodiment of a suction device, which in the 2 to 8th shown and with 122 is designated, comprises a suction container 14 ' , on which a suction head 12 ' is releasably fixed. At the suction head 12 ' is a suction fan device 22 ' arranged (see the 12 to 14 ).

On the holder is a pantry 42 ' with a pantry 44 ' arranged ( 12 and 13 ).

The holder 38 ' is formed in two parts with a first part 52 ' , which on the holder 38 ' firmly fixed, and a second part 54 ' which is detachable on the first part 52 ' sitting.

The pantry 44 ' is between the first part 52 ' and the second part 54 ' educated.

The pantry 44 ' takes as above using the pantry 44 described a hose 48 on, which in particular folded in the pantry 44 ' is positioned.

Out of the hose 48 can be as described above Suction bag 50 produce, which in an interior of the suction material container 14 in a suction operation of the suction device 122 are positioned.

The suction device 122 has a Einsaugraum 34 ' on which a suction connection opening is arranged, to which a suction hose can be connected, in particular via a connecting piece.

The holder 38 ' has a wall 62 ' on which at the first part 52 ' is formed.

On the wall 62 ' is a barrier device 106 ' arranged. The locking device serves to prevent the ingress of suction material from the Einsaugraum 34 ' in a pressure compensation room 100 ' around a bag 50 ,

In one embodiment, the barrier means comprises 106 ' a filter device 124 ( 3 to 5 ). The filter device 124 includes at least one filter 126 which is dust-impermeable. The filter 126 has a dirty side 128 , which the suction space 34 ' facing, and a clean side 130 , which the pressure compensation room 100 ' is facing.

About the filter 126 Openings are provided over which the pressure equalization space 100 ' pressure effective with the Sauggebläseeinrichtung 22 ' is connectable.

The filter device 124 as a whole is via a fixing device 132 on the holder 38 ' Preferably fixed such that for the solution or for the replacement of the filter device 124 or the filter 126 a tool is needed. As a result, in particular an unintentional removal of the filter device 124 prevented.

In an alternative embodiment of a locking device 106 ' which also with the filter device 124 can be combined is a barrier device 134 ( 3 . 6 . 7 ) intended.

The damper device 134 comprises as a blocking element (at least) a blocking flap 136 , which is arranged to be movable and in particular pivotable.

In one embodiment, the trapdoor is 136 arranged so that they are in the suction space 34 ' can swing.

The blocking flap 136 sits at an opening 137 , which with the pressure compensation room 100 ' connected is.

The damper device 134 is designed so that in a suction operation, the negative pressure of the Sauggebläseeinrichtung 22 ' the blocking flap 136 opens and thereby releases the corresponding opening. This in turn becomes a pressure-effective connection between the suction fan device 22 ' and the pressure compensation room 100 ' produced.

Since the negative pressure by the Sauggebläseeinrichtung 22 ' also causes a suction effect, the infiltration of suction material through the corresponding opening at the open flap 136 in the pressure equalization room 100 ' essentially prevented.

If no negative pressure by the Sauggebläseeinrichtung 22 done, then is the blocking flap 136 closed (cf. 5 ) and in particular spring-loaded closed, and there can be no suction material from the Einsaugraum 34 ' in the pressure equalization room 100 ' reach.

At the in 3 embodiment shown is both a filter device 124 as well as a barrier flap device 134 intended.

In a variant of an embodiment ( 8th ) are a first filter device 124a and a second filter device 124b on the corresponding holder 38 ' arranged.

In particular, the locking device 106 ' on the holder 38 ' arranged.

The suction device 122 works as above using the suction device 10 described.

On the basis of the suction device 122 Below are the basic steps for filling the pantry 42 ' explained with a new hose when the "old" hose is about to be exhausted.

In 12 is a view shown in which still a bag of suction material 50 on the holder 38 ' is arranged. The hose 48 in the pantry 44 comes to an end. It will be a "last" bag 138 made at its lower end as described above with a closure corresponding to the first closure 88 is closed.

This bag 138 covers the suction-suction-leading areas of the suction device 122 from.

The vacuum bag 138 In particular, it is produced and thereafter no further cleaning operation is carried out, so that the suction bag 138 is essentially empty. (But it can on its inside by the fluid-effective connection with suction-suction-leading areas of the suction device 122 be "contaminated".)

It then becomes the suction head 12 ' from the suction container 14 ' removed and positioned so that on the holder 38 is accessible.

For example, the suction head 12 ' with his top 140 on a pad 142 switched off.

It will be the second part 54 ' of the owner 38 from the first part 52 ' solved ( 13 ). The remaining vacuum bag 138 is not removed, but remains on the first part 52 ' of the owner 38 ,

It will be a new tube 144 used. This is about the "old" bag 138 slipped over and also in the area of the storage room 44 ' imposed.

The new hose 144 gets at its lower end 146 sealed as described above to a "new" bag 146 to build.

The suction head 12 ' is back on the suction container 14 ' placed.

The "old" vacuum bag 138 is now in the new bag 146 ( 14 ) contain. He can now or at a later date (if a cleaning operation has taken place and the new bag of suction bags 146 filled) in the new bag 146 be pulled, that is shifted so that he no longer s.der holder 38 hangs.

This makes it possible to use a new suction hose, from which corresponding suction bag can be formed, without the operator being in contact with suction material or areas of the suction device which are exposed to suction material 122 comes.

Otherwise, the suction works 122 as described above.
