Description

Device for machining a filler product

The invention relates to an apparatus for machining a filler product from a single or multi-ply continuous paper web, such as a packaging material manufacturing machine. Generic filler material production devices are set up, for example, in logistics centers as a portable, mobile unit in order to provide padded material for the packaging of an article. The padding material is obtained from a paper web roll which is space-saving in comparison with the padding material, in particular a recycled paper roll, or from a stacked recycled paper web. To produce the cushioning material, the paper web is pulled from a roll and reshaped to form air pockets that cause damping between the object to be packaged and the outer packaging.

In order to be able to rapidly package a large selection of items to be packaged, the items are stowed on the basis of standardized packaging processes and in packagings of standardized sizes. It is important that any necessary filling material is always available in consistent cushioning quality and predefined three-dimensional dimensions, in order to enable an efficient workflow and to reduce logistics costs.

A known device for machining a three-dimensional packaging product or filler product, which is used in the technical field described above, is described in DE 10 2012 018 941 AI.

The known manufacturing device creates a prefabricated in widths, heights and length dimension filler product from a paper web material. For this purpose, the known device is fed to a paper web in a conveying direction and then formed in a deformation station, the paper web into a three-dimensional filler strand. Subsequently, in the conveying direction, filler products of a predefined length are separated from the filler strand by a rotary cutter. However, as the rate of delivery and delivery of the filler products increases, the prior art device increases the risk that immediately after separation of a filler product from the filler strand, further transport of the trailing filler strand is impeded by the separated leading filler product and a delivery jam occurs. Due to the high delivery speeds, congestion often results in clogging that can only be remedied by manual operator intervention on the manufacturing device, resulting in an interruption of the packaging process.

It has been found that in the event of a backlash, operators tend to try to clear the production jam through the filler material discharge opening. Since the cutting blade of a rotary cutter represents a significant risk of injury, commercially available production devices usually have additional design protection measures that prevent manual intervention through the discharge opening in the manufacturing device. However, the more expensive construction with protective flaps and the like complicates the maintenance process necessary on the production apparatus in known models in order to properly eliminate the accumulation jam and to put the apparatus back into operation. Moreover, the additional design measures increase the initial cost of such a device.

It is an object of the invention to overcome the disadvantages of the prior art, in particular to provide a device for machining a Füllmaterialerzeugnisses having a high delivery speed with low material jam probability, and meets high security requirements.

This object is achieved by the subject matter of claim 1. Thereafter, an apparatus for machining a filler product from a single or multi-ply continuous paper web is provided. The manufacturing apparatus comprises a conveyor for drawing the paper web into the apparatus, whereby a conveying direction is defined, and a cutting device for separating the filler product from a three-dimensional filler material strand formed in the apparatus from the paper web. According to the invention, a removal device, which transports the separated filler product away from the cutting device, adjoins the cutting device in the conveying direction. By removing the filler product immediately at the moment of separation from the trailing Füllmaterialerzeugnisstrang a collision of the trailing Füllmaterialstrangs is avoided with the Füllmaterialerzeugnis. A paper jam in the wake of the cutting device is reliably excluded. With the measure according to the invention of conveying off the filling material product, the speed of delivery of the production device could be significantly increased and the maintenance times could be considerably reduced. Maintenance interventions due to a backfill in the wake of the cutter have been reduced to a negligible level. The removal device forms by their Nachordnung in the conveying flow relative to the cutting device effective protection against interference in the region of the cutting device of the manufacturing device through the output port, without additional design measures would be necessary.

The production device preferably operates fully automatically such that one or more filler products are manufactured and dispensed by the device on request of the user, in particular without the need for operator intervention. In particular, the paper web fed to the device is essentially two-dimensional, with defined width and length dimensions, wherein in particular the length dimension exceeds the width dimension by a multiple, and negligible height dimension represented by the paper web thickness. In particular, the device comprises a paper web receptacle, from which the feed passes the paper web into the device. The paper web can be held by the recording as a role and / or stack. The feedstock applies drive forces to the paper web in a predefined conveying direction. In particular, the conveying direction coincides with a main extension direction of the production device, in particular a housing or a housing carrier of the production device. Along the path of the paper web into and through the manufacturing apparatus, the two-dimensional paper web is formed into a three-dimensional filler strand. In particular, the manufacturing device has a tapered delivery channel. In the conveyor channel, the longitudinal edges of the paper web are turned over to the paper web center to form air gaps. In particular, the manufacturing apparatus has embossing wheels that deform the paper web to form a three-dimensional filler strand. In particular, the embossing wheels transmit driving forces to the paper web. The filler strand runs into the cutting device, which separates a section from the filler strand, in particular at predefined time and / or length intervals. It is clear that too the cutting device can further reshape the filler strand and / or can apply driving forces to the filler strand.

The subsequent to the cutting device discharge means divides the Füllmaterialerzeugnis driving forces in the conveying direction or a direction that has a predominant directional component in the conveying direction to remove the Füllmaterialerzeugnis from the working area of the cutting device. In particular, the discharge conveyor drives the separated filler product toward and / or through a discharge opening in the manufacturing apparatus so that the filler product can be reused by an operator. In particular, the discharge device transmits driving forces to the filler strand at least immediately before the cutting device separates the filler product from the filler strand. In particular, the discharge device structurally connects directly to the cutting device in the conveying direction.

In a preferred embodiment, a conveying speed communicated by the discharge device to the filling material product and / or the filling material strand is equal to or greater than the conveying speed reported by the feed of the paper web. The infeed determines a feed rate at which the paper web is fed to the manufacturing apparatus and the stripper. The discharge device engages in the paper web converted into a filler strand and conveys it further at a conveying speed in the conveying direction, which corresponds at least to the feed speed. This ensures that the filler strand is held and / or guided at least at the moment of separation both by the feed and by the discharge. In particular, the lengthening device is adapted to the discharge device and / or the feed such that a guidance of the filler material strand is already given before the separation. Due to the at least the same removal rate with respect to the feed speed, it is also ensured that after the separation of the filler product the leading edge of the filler strand from the feed and / or the lengthening device enters the drive force influence region, in particular the engagement region of the discharge device, without this having a trailing short edge the filler product comes into contact.

In a preferred embodiment, the infeed and / or the discharge device are synchronized with the length-cutting device in such a way that before and / or during the separation of the filling device. material product, the feed and the discharge device impart conveying forces to the filling material strand. It should be understood that conveying forces may be communicated frictionally, such as by frictional or gearing, or non-contact, such as by pressurizing, the filler strand, and / or the paper web or filler product. The cutting device punctually cuts through the filler strand passing through the cutting device with a conveying speed generated by the feed and / or the discharge device. In particular, the (supply) conveying speed before and during and / or after the separation is constant. The separation of the filling material product thus takes place in the conveying flow without loss of time. In addition, it is ensured that the separated Füllzeugerzeugnis learns from the moment of separation of conveying forces that prevent an undelivered remain in the manufacturing device, so that no material jam may occur. In particular, the feed, the discharge device and the Ablängeinrichtung Initialzustände and / or initial positions, which are coordinated so that in a first pass of a leading paper web section, the cutting device just then a first Füllmaterialerzeugnis separated from the reformed filler strand, immediately after the discharge conveyor the leading Füllmate - Rialstrangbeginn first announces conveyor drive forces. In particular, the removal device is driven synchronously with the cutting device in such a way that a filler product is always separated from the filler strand as soon as the removal device informs a leading edge of the filler strand removal drive forces.

In a preferred embodiment, the feed and / or the discharge device and the lengthening device are matched to one another in such a way that the filler strand is subjected to tensile stress, in particular during separation. In particular, the discharge device notifies a leading edge of the filler strand and / or the filler strand a preferably slightly higher, such as 1 to 10% higher, (discharge) conveying speed than the delivery. In particular, the removal rate is increased only shortly before and / or during the separation of the filler product. Alternatively or additionally, it can be provided that for generating the tensile stress, a distance between an engagement point of the feed into the paper web and an engagement point of the discharge device in the filler strand is temporarily increased. A standing under a slight tensile filler strand allows an exact length assembly. If cutting tools are used for cutting, they are subject to less wear. In a preferred embodiment, the device has a drive gear unit which controls and / or drives the feed and / or the discharge device so that after the separation of a filler product, the promotion of Füllmaterialstrangs is continued until an advancing in the conveying direction edge of the filler strand into engagement comes with the discharge device. In particular, the drive gear unit has a sensor for detecting driving forces and / or a timing that measures whether the leading edge of the filler strand has come into engagement with the discharge device. The drive gear unit runs after generating a filler product, in particular without intervention of an operator until the filler strand is stirred by both the feed and the discharge device. This avoids that a Füllmaterialstrangende after removal of the filler product unguided remains in the manufacturing apparatus and could cause a backlog of the manufacturing device, a flow accumulation.

In a preferred embodiment, the feed and / or the discharge device to a wheel train. In particular, the wheel train detects at least one of the paper web, filler strand and filler product between two conveying wheels arranged in particular opposite the conveying direction. Preferably, the feed and the discharge conveyor each comprise a gear train. In particular, the gear train of the feed is realized as a pair of embossing wheels, which transforms the paper web into a filler strand. Preferably, the wheel train transports the paper web, the filler strand and / or the Füllmaterialerzeugnis along the conveying direction and / or a direction of passage, which is defined by a common tangent to the respective outer peripheries of the conveyor wheels of the gear train. In particular, the passage direction is equal to the conveying direction. Alternatively, it may be provided that the directions of implementation of a gear train of the feed and a gear train of the discharge conveyor at an angle of less than 45 ° and more than 5 ° intersect.

In a preferred embodiment, the feed and / or the discharge device comprises in particular in each case one gear train with two conveying wheels arranged laterally opposite one another, in particular relative to the conveying direction. In particular, the conveying wheels of a respective gear train have different wheel diameters. Preferably, the distances between the axes of the conveyor wheels of a respective gear train with respect to the wheel diameter or the sum of the radii of the two conveyor wheels are undersized so that the conveyor wheels are resiliently biased against each other. Due to the elastic prestressing, sufficient drive force transmission to the filler strand and / or the filling material product can be ensured even with unprofiled conveying wheels. A passage through the feed or the discharge device in the region of the cutting device is made difficult by the elastic bias.

In a preferred embodiment, the feed and / or the discharge device each have at least one feed wheel. Preferably, the at least one conveying wheel comprises an elastically deformable rolling area. In particular, the delivery wheel is formed by an elastomer body, such as a PU foam body. In particular, the feed wheel has a toothing. Preferably, the feed and / or discharge device per two conveyor wheels, wherein the one has a toothing and the other impeller has a gegenleiche toothing, in which engages the toothing of the first conveyor wheel in particular driving forces. By a driving forces transmitting adhesion between the conveyor wheels and / or the discharge device, a drive force transmission to the paper web and / or the Füllmaterialstrang can be done reliably without both conveyor wheels would have to be driven. This allows a cost-effective design of the manufacturing device.

In a preferred embodiment, the cutting device has a rotary cutter which in particular comprises two tool parts which are mounted on one shaft and are arranged laterally opposite one another with respect to the conveying direction. In particular, the rotary cutter comprises a cutting pad on a tool part and a cutting edge on the opposite tool part. In particular, the substantially preferably straight cutting edge extends transversely, substantially perpendicular to the conveying direction. In particular, the cutting edge is arranged in the direction of the shaft forward and / or trailing at least one perforation nose and / or slot receiving. Preferably, one tool part has at least one perforation nose and the other tool part has at least one slot receptacle into which the perforation nose engages during one revolution of the rotary cutter.

In a preferred embodiment, the apparatus has a preforming station, which in particular is arranged downstream of the feed in the conveying direction and converts the paper web into a three-dimensional filling material strand. In particular, the preforming station is by a Formed funnel for forming the paper web and / or a train of the feed train, which is in conveying and / or embossing engagement with the paper web.

In a preferred embodiment, the cutting device has a perforation tool for introducing a perforation into the filling material strand, which comprises at least one perforation nose, at least one perforation receptacle and at least one scraper. In particular, the perforation nose and the at least one perforation receptacle, such as a slot receptacle, are associated with one another in such a way that, for perforation, the at least one perforation nose can move in and out with respect to the at least one perforation receptacle, such as the slot receptacle. In particular, the scraper is associated with the at least one perforation nose and / or the at least one perforation receptacle in such a way that, on extension, the perforated filling material strand is removed from the at least one perforation nose and / or at least one perforation receiver. In particular, the perforation tool according to the German patent application 10 2013 015 875.3 with filing date September 23, 2013 executed.

Further features and advantages of the invention will become apparent from the following description of preferred embodiments according to the accompanying drawings, in which:

Figure 1 is a perspective view of the internal structure of the manufacturing apparatus according to a first embodiment; and

FIG. 2 is a sectional view of the manufacturing apparatus according to FIG. 1.

In FIGS. 1 and 2, a device 10 according to the invention for machining a filler product is generally designated by the reference numeral 10. In the illustrations, the manufacturing device 10 is shown without a housing, so that the view is free on the housing support 13 and the invention-relevant components of the manufacturing apparatus 10. The manufacturing apparatus 10 comprises a feed 2, which conveys a non-illustrated paper web, which is in roll or stack form, from a Papieraufhahme from, for example, wound from a roll or removes a stack, and pulls in a conveying direction F in the manufacturing apparatus 10. The feed 2 comprises a feed hopper 21, which tapers from a paper receptacle, not shown, to a conveying channel running through the housing carrier in its direction of extension, which opens at an outlet opening 9. The feed also includes a subsequent directly to the feed hopper 21 gear train 23 which is rotatably mounted in the housing support 11 and the paper web tangential to the wheels conveying forces. When feeding the paper web through the hopper 21, the tubular or web-shaped unwound paper web is compressed in its volume expansion radially to the conveying direction F, so that arise by bending and folding individual paper web sections air voids, which determine a cushioning effect of the filler product to be produced.

The gear train 23 of the feed 2 is formed by two oppositely arranged along the conveyor channel conveyor wheels 23 a, 23 b, of which in particular only one is rotationally driven (not shown in detail). The rotary drive can be tapped via a not-shown gear or a toothed belt system of a drive gear unit 120. The second feed wheel 23b of the gear train 23 is mounted essentially freely rotating. The feed wheels 23 a, 23 b are in mutual engagement, so that the driving forces of the driven feed wheel 23 a are communicated to the feed wheel 23 b. As can be seen in Figure 2, the rotary shaft 25 b of the free-rotating impeller 23 b and the rotary shaft 25 a of the feed wheel 23 a with respect to the maximum outer diameter of the conveyor wheels in a undersized radial distance from one another in the housing support 13, so that a Förderradüberschneidung and thus a conveying contact region 26 between the conveying wheels 23 a, 23 b results. The conveyor wheels 23 a, 23 b are resiliently biased against each other.

The driven conveying wheel 23a is provided with an elastically deformable rolling region 24, such as a foam tread, which elastically deforms in the contact region 24 relative to the co-driven conveying wheel 23b. Both conveying wheels 23a, 23b can be made predominantly or completely from an elastic material, such as foam, or as the conveying wheel 23a can have an elastic rolling region 24 or an elastic running surface, for example made of foam. Alternatively, the conveyor wheels 23a, 23b are designed as toothed wheels which engage in each other and in the paper web and also achieve an embossing of the air inclusions in the paper web to form a Füllmaterialerzeugnisstrang. The gear train 23 grips the paper web preformed by the hopper 21 and forms creases and folds in the paper web by means of the pressing force acting on the preformed paper web between the feed wheels 23a, 23b so that a three-dimensional filler material strand is preformed with cushioning air pockets. The conveying direction F is defined in particular by a common tangent to the two conveying wheels 23 a, 23 b of the feed 2. Alternatively, the conveying direction F is determined by strand passage of the paper web or of the filling material strand when passing through the device 10. The hopper 21 and the gear train 23 of the infeed 2 together form a preforming station. An example of a feed that directs Vorformarbeit is given by the preforming station according to DE 10 2012 018 941 AI, the contents of which should be included in the description of the figures.

In the conveying direction F is connected to the feed a likewise in the housing support the cutting device 4. The lengthening device has a perforation tool of the type which is known, for example, from German patent application 10 2013 015 875.3 with filing date 23.09.2013, the content of which is to be included in the description of the figures.

The perforation tool comprises two tool parts 127, 129 arranged opposite each other substantially symmetrically with respect to the conveying direction. The tool parts 127, 129 are each mounted rotatably in the housing carrier 13 on a shaft 27, 27 '. A tool part has a cutting edge 37 which, in the course of a rotation about the shaft 27, cuts through a filler strand transported in the conveying direction F. The second tool part, which rotates synchronously with the first about the shaft 27 ', has an insulation pad 183. The cutting pad 183 and the blade 37 come to cut the filler product from the filler strand in cutting contact. The shafts 27, 27 'are rotationally driven by a respective drive gear 161, 161' which rotationally drive the rotary cutter formed by the cutting edge 37 and the cutting pad 183. The toothed wheels 161, 161 'each have rotationally symmetrical, in particular circular, material recesses 163 distributed uniformly along the circumference. By means of the material recesses 163, the weight of the drive gears 161, 161 'is reduced and the rotational inertia is reduced.

In the conveying direction F, a removal device 6 directly adjoins the cutting device 4. The discharge device 6 has two conveyor wheels 61, 63, whose rotary shafts 69, 69 'on opposite sides of a conveyor channel running along the conveying direction F. of the housing support 13 are arranged. The feed wheel 61 has a larger diameter than the feed wheel 63. The shaft 69 'of the feed wheel 63 is arranged in the conveying direction at a closer distance to the shaft 27' of the cutting device 4 than the shaft 69 to the shaft 27. The distance between the shafts 69, 69 'of the discharge conveyor is relative to the maximum outer diameters of the conveyor wheels 61, 63rd undersized, so that a under compression biased contact portion 66 between the conveyor wheels 61, 63 is formed. Due to the arrangement of the shafts 69, 69 ', which is not exactly perpendicular to the conveying direction F or offset in the conveying direction F, a discharge direction D results between the conveying wheels 61, 63, which crosses the conveying direction F defined by the infeed and / or the housing carrier extension , The removal direction D is defined by a common tangent to the conveyor wheels 61, 63. The conveyor wheels 61, 63 have an elastic tread or are predominantly or completely made of an elastic material, such as a foam.

The discharge opening 9 of the device 10 is covered by a pivotally mounted flap 91. The flap 91 is designed in the manner of a check valve. In particular, the flap 91 is mounted in the dispensing opening 9 such that the discharge direction D is substantially perpendicular to the closed flap 91 by the conveyor wheels 61, 63.

The shaft 69 of the feed wheel 61 has an output gear 68. The drive gear unit 120 drives a drive pinion 121, which via a toothed belt 123 rotational drive forces on the output gear 68 of the discharge conveyor 6. A tensioning roller 28 is disposed in the housing support 13 relative to the drive pinion 121 and the toothed belt 123 such that it has a bias perpendicular to the direction of the toothed belt 123 is applied to the toothed belt. The tension or deflection roller 28 contacts the untoothed outer surface of the toothed belt 123 to deflect the toothed belt. The drive gear unit 120 also generates rotational drive forces for the cutting device 4. The driving forces are transmitted via the gears 161, 161 'on the Ablängeinrichtung 4, which is not shown for clarity in the figures.

The rotational speed of the gear train 23 of the feed 2 is adjusted to the rotational speed of the conveyor wheels 61, 63 of the discharge device 6 and the rotational speed of the cutting device 4 such that the cutting device 4 reaches a cutting position only when a provided by the feed 2 filler strand in Engagement with the conveyor wheels 61, 63 of the discharge device 6 comes. The cutting position is defined by that the cutting edge 37 is in contact with the cutting pad 183 and in particular is aligned parallel thereto. Furthermore, provision may be made for the device to have a predetermined maintenance position for a first commissioning in order to define a predefined position of cutting device 6, in particular of the rotary cutter.

The gear train 23, 62 of the feed 2 and the discharge conveyor 6 and the gears 161, 161 'of the cutting device 4 are working synchronously, in particular at different speeds. That is, the conveying wheels 23a, 23b, 61, 63 and the gears 161, 161 'rotate in a predetermined time and speed relationship with each other.

The drive gear unit 120 may be designed via a sensor or timing not shown in such a way that after cutting a Füllmaterialerzeugnisses from a filler strand at least the feed 2 as long runs until the filler material trailing leading edge of the Füllmaterialstrangs comes into engagement with the discharge device 6. This ensures that the system stops in a predefined operating state and that no accumulation of fluid can occur during the re-run.

The rotational speed of the cutting device 4 is preferably matched to the rotational speed of the feed 2 and the discharge device 6 such that a predefined length of the filler strand along the conveying direction F passes through the device 10 within a revolution between cutting position and cutting position. Preferably, the speed of the cutting device is adjustable relative to the conveying speed of the feed 2 and the discharge device 6 to adjust the length of the filler product to be produced. Preferably, the rotational speeds are synchronized in a predetermined relationship to each other. This object is achieved by a transmission of the drive gear unit 120 and by the provided by the drive pinion 121, a gearbox of the feed, the output gear 68 and the gears 161, 161 'translation.

The production process of a filling material product is as follows: The paper web is conveyed through the feed 2 into the device 10 in the conveying direction F along the longitudinal direction. Stretched the housing support 13 and preformed when passing through the gear train 23 of the feed 2 in a three-dimensional Füllmaterialerzeugnisstrang. The Zufördergeschwmdigkeit the feed 2 is synchronized to the rotational speed of the rotary cutter of the cutting device 4 and its predefined initial rotational position such that the gear train 62 of the discharge conveyor 6, which includes the conveyor wheels 61, 63, comes into a conveying engagement with the Füllmaterialstrang before the cutting edge 37 of the cutting device 4 reaches the cutting position to cut off the filling material product from the filler strand.

The discharge device 6 applies to the filler product at a discharge speed which is greater than or equal to the Zufördergeschwmdigkeit applied by the feed 2 on the Füllmaterialstrang. This will ensure that no paper jam can occur. Preferably, by a between 0.1% and 20%, in particular between 0.1% and 10%, preferably between 0.1% and 5% higher Abfördergeschwindigkeit the filler strand at the moment of separation under tensile stress within the device.

The filler product is subsequently transported by the discharge device 6 in the direction of the discharge opening 9, wherein the conveying speed is high enough to open the shutter 91. Alternatively, the drive gear unit 120, synchronized with the cutting device 4 and / or the discharge device 6, opens the closing flap 91 at intervals or at a predefined time interval for cutting off.

The cutting edge 37 of the length-cutting device 4 is integrated in a perforating tool with a nasal drawing part 127 and a receiving tool part 129 which, when separating the filling material product, produce shape-retaining perforations on the trailing filler material edge and the preliminary filler edge. The receiving tool part 129 has a cutting pad 183 and slot recesses 177 a, 177 b, in the perforation 45 a, 45 b of the opposite nose tool part 127 penetrate. In the nose tool part 129, a scraper 57 is provided which is designed as a PU foam bar in order to remove the filler material strand from the perforation tool after the perforation. The features disclosed in the foregoing description, in the figures and the claims may be of importance individually as well as in their combination for the realization of the invention in the various embodiments.
