Definitions

  • the invention relates to a device for receiving and cutting at least two film rolls, paper rolls or the like.
  • a device for receiving and cutting at least two film rolls, paper rolls or the like For household needs, in particular cling films, aluminum foils or bread paper with a housing in which the rolls are arranged and which has a removal slot, and with one of the removal slot assigned and movable along this cutting device.
  • a pick-up and cutting device for film rolls, paper rolls or the like This type is known from DE-PS 28 49 457.
  • the device is used to hold two such rolls, for example for cling film, aluminum foil or bread paper for household needs.
  • two compartments for accommodating one roll each are arranged in a housing one above the other.
  • These two compartments are each assigned a horizontally extending removal slot and a cutting device which can be moved along this removal slot, by means of which the film or paper protruding from the corresponding removal slot can be cut off after it has been pulled out to the desired length.
  • the cutting device consists in each case of a carriage which is above the associated removal slot via an L-shaped rail with the Ge housing connected and slidable along this. Below the removal slot, bridging it, the slide has a cutting element, for example in the form of a rotatably mounted circular knife, by means of which the film or the paper is cut off as the slide moves along.
  • the disadvantage of this known device is that a separate cutting device is provided for each compartment or for each roll, in order to be able to cut off the respectively required film or paper. This is technically complex, especially since the cutting devices also consist of many individual parts and the manufacturing costs are therefore very high.
  • the compartments are to be arranged one above the other in the known device, so that the housing is very high in, for example, four compartments and thus there are difficulties in mounting the device, for example, under wall cupboards in the kitchen.
  • the object of the invention is to further develop the known receiving and cutting device for film rolls, paper rolls or the like in such a way that it manages with only one cutting device common to all rolls.
  • the invention proposes a magazine which holds the rolls and which is mounted in the housing so as to be able to remove and cut off the film or paper required in each case from the corresponding roll in a predetermined removal position about an axis.
  • a receiving and cutting device for film rolls, paper rolls or the like, designed according to this technical teaching. has the advantage that it has a common cutting device for all rolls. Accordingly, only a single removal slot is provided in the housing for all rolls. As a result, the technical outlay of the device is considerably reduced, since, for example, with four rollers, four cutting devices would no longer have to be provided as before, but only one. With more recordable rolls, the number of individual parts is considerably reduced.
  • the rollers are aligned parallel to the rotation or swivel axis of the magazine. If three or more rollers are to be accommodated in the housing, these should be distributed evenly around the circumference, for example in the case of four rollers with an angular spacing of 90 °.
  • all the rollers have a common removal position into which the magazine is rotated accordingly, this removal position preferably being in the region of the removal slot in the housing. If a certain roll is required, the magazine is thus rotated into the specified removal position so that the tip of the film or paper is visible in the removal slot, and the beginning of the film or paper is pulled out to the desired length and then actuated cut off the cutting device.
  • the device according to the invention with a rotatable magazine also has the advantage that the housing increases in depth, but does not build too high in height, so that the housing itself can be hung on the wall with four castors under wall cupboards.
  • this has part-circular cylindrical troughs for receiving a roll, the troughs also being assigned a part-circular cylindrical, coaxially pivotable cover for opening and closing the trough, with a trough between the cover and the cover when the trough is closed slot is defined for the film or paper.
  • a magazine design has the advantage that the rollers can be inserted into the receiving trays from the front after the cover has been pivoted into the open position. This proves to be particularly advantageous if the rollers cannot be inserted laterally into the housing due to the limited space available.
  • the trays of the magazine are rigidly connected to each other. In the closed position, the covers prevent the rollers from falling out of the tubs when the magazine rotates, the tip of the film or paper being clamped by the lip-like feed-through slot. This also prevents the tip from kinking.
  • the cover In a development of the cover, it is resilient and rests resiliently on the inserted roller in the closed state. This prevents the roll from rolling up or rolling off within the tub when the magazine is rotated. Rather, by holding the roll, it is ensured that the tip of the film or paper protruding from the lead-through slot retains its length, even when the magazine is rotated several times, which it experienced during the previous cut.
  • a latching device is provided for the closed state between the tub and the cover.
  • the trough has stops for the inserted roller at the end, so that the tip can also be gripped laterally and pulled out.
  • the magazine has slotted tubes for receiving a roll.
  • the rollers are laterally in the tubes of the magazine to be inserted, the tip of the film or of the paper being guided to the outside through the lip-like slot formed in the tube and being held like a pair of pliers without kinking downwards.
  • the tubes preferably each have at least one retaining spring, which rests resiliently when the roller is inserted and thus fixes it when the magazine is rotated and springs against it when pulled.
  • the retaining spring is preferably designed as a spring tongue extending in the longitudinal direction of the tube, which is cut out of the jacket of the tube. In terms of production technology, this represents a simple possibility for forming the retaining spring.
  • the magazine has troughs which are part-circular in shape and which are suspended in the housing such that they can pivot about an axis, each for receiving a roll. Due to the rollers lying in these trays, they always adjust when the magazine is rotated so that the opening of the trays is at the top due to the gravitational conditions.
  • the magazine is part-circular cylindrical and in each case rotatable about an axis in the housing mounted troughs for receiving one Has role, the tubs a common planetary gear is assigned such that the openings of the tubs are always at the top when turning the magazine.
  • a fourth embodiment of the magazine proposes that this ge through a fan cross to hold one role is formed, a hold-down bar for the definition of a lip-like through-slot for the film or the paper being arranged in each compartment of this interlocking element, which can be pivoted about an axis and can be fixed on the interlocking element.
  • a preferred, fifth embodiment proposes that the magazine is formed by sector-like compartments for receiving one roll each and that each compartment has a preferably substantially S-shaped arched cover which can be pivoted about an axis parallel to the axis of the magazine, for opening and closing the cover Subject is assigned, with a closed slot for the film or paper is defined between this and the cover when the compartment is closed.
  • a magazine designed in this way ensures that the various rolls are securely stored in their compartments, only the corresponding cover having to be pivoted into the open position to insert a new roll in order to close the cover again after inserting the new roll. This can be done quickly and safely.
  • the wings are preferably essentially S-shaped and, in particular, curved in the form of an elongated "S", with a large arc and with a small arc, the small arc being located in the region of the front lip defining the through slot. This ensures an optimal definition of the role within the subject.
  • the compartments are preferably formed by essentially radially extending partitions which have radial slots in the region of the side walls of the magazine.
  • the sector-like compartments of the magazine are thus defined by a dividing wall cross or by a dividing wall star, the dividing walls being designed as resilient wings due to the slots at the ends forms, which exert a spring pressure on the rollers arranged in the compartments.
  • spring pressure is exerted on the roller tips so that they are held in place.
  • the longitudinal edge of the cover facing the through-slot is structured, in particular roughened, at least in partial areas.
  • the structuring is preferably carried out in the middle area.
  • the structuring of this profile edge has the advantage that it digs into the tip of the roll due to the spring force and in this way holds it securely without it accidentally slipping out.
  • the roles are preferably loosely in their compartments.
  • the rollers are held within the compartments by the spring force of the partitions.
  • the lead-through slot opens by 0.2 to 0.3 mm, for example, so that the film can be pulled out without problems.
  • the covers are each preferably pivotably mounted in the front side walls of the magazine by means of a pin / recess.
  • a pin / recess By simply bending the Side walls can snap the pins or recesses of the covers into the corresponding recesses or pins on the inside of the side walls of the magazine.
  • the magazine thus consists of a few parts and is therefore easy to manufacture.
  • the covers each have laterally projecting extensions which, when the cover is closed, are fixed in corresponding recesses in the side walls of the magazine and in particular snap into place. This ensures in a technically simple manner that the domed covers cannot open by themselves.
  • the lateral extensions of the covers also serve as a handle for the operator in order to be able to open and close the cover in a simple manner.
  • a sixth embodiment of the magazine which is provided for two rollers, has pivot arms for these two rollers, by means of which they can each be pivoted about the axis into the removal position.
  • This fifth embodiment thus differs from the first four embodiments in that the magazine does not perform an (endless) rotary movement, but rather a pivoting movement by means of which the two rollers are pivoted alternately into the respective removal position against stops.
  • the removal positions for the two roles do not have to match, but each role can have its own removal position. It only has to be ensured that the then unequal lengths of the film or paper come to rest in the area of the removal slot.
  • the magazine can thus be designed like a swing.
  • the magazine can provide special receiving elements for the two rollers, with the receiving element Mente can serve as described above in the first four embodiments, so tubs (optionally with cover) or slotted tubes.
  • the magazine be rotatably or pivotably mounted in the side walls of the housing by means of pins / recesses coaxial with the axis. This represents a technically simple possibility of arranging the magazine within the housing of the device, the magazine being able to be snapped into place by simply bending the side walls of the housing outwards.
  • the one pin is formed by a coaxial rotary knob of the magazine, the corresponding recess in the side wall of the housing having an opening.
  • This pin in the form of a rotary knob serves for the rotary bearing within the housing and that the pin can also be used as a rotary knob due to the opening to rotate or pivot the magazine into the corresponding position by the pin in the form of the knob is accessible through the side wall of the housing.
  • a braking device is provided between the housing and the magazine, in particular between a rotary knob of the magazine and the housing. Such a braking device prevents the magazine from rotating independently due to unevenly heavy rollers.
  • a latching device is provided between the housing and the magazine for determining the removal position for the rollers.
  • a locking device enables the magazine to be rotated or swiveled into the correct position in a reliably fast manner.
  • This locking device preferably has some play to improve the gripping conditions.
  • the receiving elements of the magazine for the rolls are stored in the magazine by means of spring-loaded clamping cones. This is provided in particular for the embodiment with the fan cross.
  • the cutting device has a carriage which is connected above the removal slot via a rail-shaped guide to the housing and can be displaced along this and which has a cutting element below the removal slot
  • the guide for the carriage is formed by two mutually parallel and spaced guide rails, which are elastically bendable against each other and on which the carriage is attached.
  • Such a guide has the advantage that the slide can be easily moved along the two guide rails without the risk of tilting and thus a stopping of the slide movement, since the guide rails adapt to the tilt angle of the slide due to their elasticity.
  • the slide can preferably be clipped onto the guide rails. This has the advantage of simple assembly of the slide.
  • the cutting device has a carriage which is connected above the removal slot via a rail-shaped guide to the housing and can be displaced along the same and which has a cutting element below the removal slot
  • a rail having an edge is arranged on the housing and that the slide has a roller rolling on the edge of the rail when the slide is moved longitudinally.
  • the rail and roller are preferably made of (hardened) metal.
  • the edge of the rail can enclose an angle of 90 °, for example, so that the user cannot cut at this rail edge.
  • By rolling the roll on the rail edge the material in between is divided by a squeezing process.
  • This system is particularly suitable for transparent films, but also works perfectly with aluminum foils and bread paper and has the particular advantage that no holding elements, for example in the form of rubber rolls on both sides, are required.
  • the roller is preferably mounted so as to be longitudinally displaceable on its axis of rotation. This has the advantage that the roll does not always run along the same circumferential line on the rail edge during the longitudinal displacement, but that the roll gradually moves upwards due to the unavoidable tilting of the slide, so that the entire circumferential surface of the roll is evenly stressed.
  • the rail has a rectangular cross section and can be inserted in a receiving slot in the housing. This means that all four edges of the rail can be used by inserting them accordingly.
  • An additional cutting system provides that the roller is connected to a coaxial circular knife and that a groove is formed between the rail and a housing strip parallel to it, into which the circular knife protrudes.
  • This circular knife performs a conventional cutting process and is particularly suitable for aluminum foil and bread paper.
  • the film or paper to be cut is stretched between the rail and the housing strip.
  • the transparent film is separated from the rail / roll.
  • a kitchen paper roll separate therefrom is mounted on a crossbar of the housing below the magazine. This represents an additional possibility for accommodating a roll, which, however, does not require a cutting device, since the kitchen paper is provided with its own perforation.
  • a storage compartment for supply rolls is provided above the magazine in the housing.
  • the housing has a front flap with a cutting device arranged thereon, so that after opening the front flap, which preferably has a latching device in the open position, the magazine can be refilled in a simple manner.
  • the cutting device for the receiving and cutting device according to the invention for film rolls, paper rolls or the like described above and claimed in claims 22 to 26, with its features, represents an independent invention which is not tied to the subject matter of the main claim with the formation of a magazine, in particular also not to a device for several film or paper rolls len.
  • the cutting device according to the invention can also be provided for a device which has only a single film or paper roll or the like. This independence of the inventions applies equally to the design of the slide guide (claims 22 and 23) and to the design of the cutting elements (claims 24 to 26).

  • This magazine 3 for the rollers 1 is rotatably supported about an axis A in the side walls 4 of the housing 2, a rotary knob 5 serving as the rotary actuation, as can be seen in particular in FIG. 3.
  • the magazine 3 consists of four troughs 6, which are essentially semicircular and are arranged uniformly around the axis A with an angular distance of 90 °.
  • These tubs 6 each serve for receiving a roll 1, as can be seen in the tub 6 at the bottom right, for example in FIG. 2.
  • the tubs 6 are each designed as rings 7.
  • a cover 8 for each of the tubs 6 can be pivoted coaxially into the tub 6 in such a way that the cover 8 can be brought into an open position for inserting a new roll and then into a closed position in which the tub 6 is completely through the cover 8 is covered.
  • the covers 8 are also designed as part-circular cylinders and each have a ring 9 at the end, by means of which the cover 8 can be swiveled coaxially in the rings 7 of the tub 6.
  • the covers 8 are each resilient in such a way that they rest against the rollers 1 within the tubs 6 and thus fix them.
  • the different positions are indicated in dashed lines in the cover 8 at the bottom right in FIG. 2, the end position of the cover 8 being indicated in the solid line.
  • a feed-through slot 10 is defined between it and the tub 6 for the start of the film or paper 11 wound on the roll 1.
  • a latching device 12 is provided between the cover 8 and the trough 6, as can be seen in particular in FIG. 1.
  • This locking device 12 is formed between the two rings 7 and 9 of the tub 6 on the one hand and the cover 8 on the other.
  • the tubs 6 are each provided with stops 13 at their ends, which fix the rollers 1 in their tubs 6.
  • a different roll 1 is arranged in each of the four tubs 6.
  • the beginning of the film or paper 11 projects through the lead-through slot 10 between the cover 8 and the tub 6.
  • the magazine 3 can be rotated by hand about the axis A until the corresponding roller 1 is in the removal position, as shown in FIG Tub 6 is shown at the bottom right.
  • the visible beginning of the film or of the paper 11 protruding through the through-slot 10 projects in this removal position through a horizontally extending removal slot 14 which is formed in a front flap 15 of the housing 2. By pulling on the beginning of the film or paper 11, this can be pulled out to the desired length through the removal slot 14.
  • a cutting device 16 which can be displaced parallel to the removal slot 14 and which is to be described in more detail in two exemplary embodiments with reference to FIGS. 17 and 18 is used for cutting.
  • the cutting device 16 shown in FIG. 17 is implemented except for the formation of a guide for this cutting device 16 in the first embodiment of the device shown in FIGS. 1 to 3.
  • the cutting device 16 consists of an L-shaped slide 17. This can be displaced along the removal slot 14 of the housing 2 by means of a guide.
  • the guide basically provides two guide rails 18 in all the embodiments of the device, which are formed parallel to one another and at a distance from the housing. The special thing about these guide rails is that they are elastically bendable against each other.
  • the carriage 17 can be clipped onto the guide rails 18 by corresponding recesses 19.
  • FIGS. 17 to 19a to f Different shapes of the guide rails 18 can be seen in the drawings, in particular in the special representations of FIGS. 17 to 19a to f.
  • the basic principle of the elastically bendable guide rails 18 is that when the carriage 17 is moved along these guide rails 18, the carriage 17 inevitably with respect the longitudinal extent of the guide rails 18 is tilted somewhat, so that with rigid guide rails 18 this tilt would result in the carriage 17 no longer being able to be moved. Due to the elastic bendability of the guide rails 18, however, these adapt to the tilting of the slide 17, so that it can be moved along the guide rails 18 without problems, no matter where the slide is touched. So that the carriage 17 does not jump out of the guide rails 18 at the end, these are preferably provided with stops in this end region.
  • FIG. 17 Another special feature of the cutting device 16 lies in the design of the cutting elements assigned to the carriage 17.
  • a rail 20 made of metal and having a rectangular cross section is inserted below the removal slot 14 in a receiving slot of the housing.
  • the special thing about this rail 20 is that it has an edge 21 which, in the exemplary embodiment shown, encloses an angle of 90 °. This angle can also be slightly larger or smaller. In any case, the edge 21 ensures that a user cannot cut it.

  • the roller 22 is mounted on this axis of rotation D so as to be longitudinally displaceable. For the cutting process, this roller 22 rolls when the slide 17 is moved on the edge 21 of the rail 20 after the film or paper 11 has been brought between the rail 20 and the roller 22 when the slide 17 is in one of the two extreme positions, so that the film or the paper 11 can be pulled out through the removal slot 14. This rolling of the roller 22 on the edge 21 of the rail 20 crushes the film or paper 11 and divides it in the process.
  • This system is particularly suitable for transparent films, but also works very well with aluminum foil or bread paper.
  • the roller 22 Due to the sliding movement of the carriage 17 under slight pressure, due to the unavoidable tilting, the roller 22 gradually moves upward on the axis of rotation D, so that the entire circumferential region of the roller 22 is stressed. In the end position after the cutting process, the roller 22 then automatically slides down again on the axis of rotation D.
  • FIG. 18 represents a further development of the exemplary embodiment in FIG. 17.
  • This also has a rail 20 and a roller 22 rolling thereon, as well as a circular knife 23 coaxial with the roller 22, which is firmly connected to the roller 22 .
  • This unit comprising the roller 22 and the circular knife 23 is also mounted so as to be longitudinally displaceable on the axis of rotation D.

  • the latter is stretched between this housing strip 24 and the rail 20, so that a conventional cutting process is carried out by the circular knife 23 if the carriage 17 is displaced.
  • This system is particularly suitable for aluminum foil and bread paper, but is also suitable for transparent films in the same way. Since the exemplary embodiment in FIG. 18 thus combines the two cutting systems, this cutting device 16 represents an optimal possibility for cutting a wide variety of materials, since the corresponding system carries out the squeezing or cutting process in accordance with the respective material.
  • the magazine 3 has a rotary knob 5 which is led out of the housing 2. This is mounted in a recess 28 in the side wall 4.
  • the braking device 26 consists of an arcuate spring 29, which can be pivoted by arms 5 'of the rotary knob 5 to the outside in that the arms 5' abut frictionally on the inside of the spring 19. This braking device 26 prevents the magazine 3 from rotating independently due to rollers 1 of unequal weight.
  • the locking device 27 is defined on the one hand by the spring 29 and on the other hand by a second spring 30, an intermediate distance being defined between them. In this intermediate distance 31, the arms 5 'of the rotary knob 5 engage and define the removal position of the respective roller 1.

  • the spring 30 is designed in accordance with the spring 29, i.e. it can be pivoted outwards. In order to bring another roller 1 into its respective removal position, the rotary knob 5 is therefore rotated further along the arrow. Since the spring 30 is provided with a run-up surface 32, this is pivoted outwards by the respective arm 5 ', so that the arm 5' can pass the spring 30 and the subsequent arm 5 'of the rotary knob 5 can snap into place.
  • FIGS. 1 and 2 it can also be seen that a separate kitchen paper roll 34 is arranged below the magazine 3 on a cross bar 33. Above of the housing 2, this has a storage compartment 35 for supply rolls 36 or, as in the exemplary embodiment shown, for breakfast bags.

  • FIGS. 12 to 16 A preferred embodiment is shown in FIGS. 12 to 16.
  • the magazine 3 is rotatably mounted in the side walls 4 of the housing 2 about the axis A.
  • the magazine 3 has pins which are coaxial with the axis A, one pin defining the rotary knob 5 of the magazine 3.
  • the side walls 4 of the housing 2 each have recesses 49, one recess 49 for the pin in the form of the knob 5 having an opening 50 through which the knob 5 of the magazine 3 passes is accessible from the outside and in this way the magazine 3 can be rotated within the housing 1.
  • the side walls 4 of the housing 2 are bent slightly outwards, so that the pin and the rotary knob 5 are released. 14 shows the magazine 3 in the removed state.
  • the magazine 3 defines sector-like compartments 41, which are formed by essentially radially extending partitions 41a. These dividing walls 41a have radial slots 41c in the region of side walls 41b of the magazine 3 perpendicular to the axis A, which make the wing-like dividing walls 41a spring.
  • a roller 1 is arranged in each of the compartments 41. To a To prevent the rollers 1 from falling out of their compartments 41, each compartment 41 is assigned an essentially S-shaped curved cover 8, which is pivotably mounted about an axis A parallel parallel to the axis A, so that the corresponding pivoting of the covers 8 Compartments 41 can be opened and closed.
  • the covers 8 are pivotally mounted in the side walls 41b of the magazine 3, by means of corresponding pins and recesses which are locked together by bending the side walls of the magazine 3 outwards.
  • the inner sides 51 of the side walls 41b can have sliding grooves which open into the recesses.
  • each In the closed state of the covers 8, these each define a through-slot 10 between them and the partition walls 41a of the magazine 3, through which the respective front end of the film or paper 11 is guided under a slight clamping pressure.
  • the longitudinal edge 8a of the cover 8 facing the through-slot 10 is structured, in particular roughened, in the central region. This structuring has the effect that when the cover is closed, the longitudinal edge 8a with the structure elevations digs into the film or paper 11, thereby ensuring a secure hold which prevents the front end of the film or paper 11 is accidentally pulled out.
  • the rollers 1 lie loosely in their compartments 51. Due to the resilience of the wing-like Partitions 41a hold the rollers securely in their compartments 51. This means that when the magazine 3 is rotated in the direction of the arrow P in FIG. 15, the rollers 1 do not roll up and the tip of the film or paper 1 protruding through the through-slot 10 is drawn in. By simply pulling the front end of the film or paper 11 in the direction of arrow Z in FIG. 15, the longitudinal edge 8a of the cover A is lifted somewhat from the adjacent partition 41a, for example by 0.2 to 0.3 mm, so that the tip of the film or paper 11 can be easily pulled out and the roller 1 rotates in the direction of arrow P '.
  • the longitudinal edge 8a of the cover 8 goes back into its contact position with the adjacent partition 41a and fixes the tip in particular due to the structuring of the longitudinal edge 8a.
  • the magazine 3 can then be rotated further in the direction of the arrow P in order to bring another roll 1 into the removal position.
  • the magazine 3 can remain in the housing 2. It is only necessary to fold down the front flap 15 so that the magazine 3 is freely accessible.
  • the magazine 3 is not rotatable, as in the previous embodiments, but pivotable. Otherwise, this embodiment of the device is only intended for two rollers 1.
  • the magazine 3 consists of double-armed swivel arms 48, between the corresponding ends of which a receiving element for the rollers 1 is arranged.
  • These receiving elements can be designed in accordance with those as have been described with reference to the preceding embodiments.
  • the two rollers 1 are pivoted into the respective removal position by means of the magazine 3, both rollers 1 having their own removal position.
  • this is the position at the bottom right and for the upper roller 1 the position at the top right after the pivoting arms 48 have been pivoted accordingly.
  • the advantage of the device described with the aid of various embodiments is that only one cutting device 16 is provided for all the rollers 1, with the rollers 1 being arranged in a magazine 3 for this purpose, which is rotated or rotated with the rollers 1 into the corresponding removal position can be pivoted so that the film or the paper 11 can be cut off by means of a cutting device 16.
  • the cutting device 16 is characterized by its functional reliability.
