This patent application is a U.S. National Stage Application of PCT/EP2018/068972, filed Jul. 12, 2018, which claims priority to German Patent Application No. 102017115918.5, filed Jul. 14, 2017, each of which is incorporated herein by reference in its entirety.
The disclosure relates to an apparatus for the production of a tube-like packaging material from a paper strip. The production of the packaging material can take place purely manually or machine-supported. The disclosure also relates to a packing station with an apparatus according to the disclosure.
An apparatus for the manual production of a helical-shaped packaging material is known from DE 20 2012 009 025 U1. The apparatus comprises a seating for circumferentially gripping a wound roll of fibrous material defining an axial direction and forming an inner side from which the fibrous material strip is stripped for forming the packaging material. A fixture for the front side of the fibrous material strip roll is following up the seating in the axial direction, the inner side of the fixture narrowing towards the output opening in order to guide the stripped fibrous material strip to the output at the opening. The fibrous material strip is manually pulled out from the output opening as a spiral tube-shaped packaging material, whereby the forming of the packaging material takes place by pulling out. The manual product apparatus for the spiral-shaped packaging material is employable practically maintenance-free and fail safe. When so many packages are packed with packaging material by means of the manual packaging material product apparatus that the paper strip roll is empty, the packing staff can simply provide a new roll.
An apparatus for the automatic production of a spiral tube-like packaging material is described in DE 10 2009 015 855 A1. For the operation, a packaging material seating of the apparatus is provided with a material strip wound to a roll. The material strip roll is unwound or stripped from the inner side and is fed through a feed chute being formed cone-shaped at the inner side to a motor-driven forming teeth wheel pair of the machine forming unit. The motor-driven forming teeth wheels are gripping the packaging material in order to feed the same by the packaging material seating in the direction of the output and the forming teeth wheels are forming it in such a way that a tube-like packaging material being strengthened along its length axis by embossing is formed from a flat strip material of the roll which is preformed tube-like in the feeding chute. The filling material arrives at an output mouth piece of the housing carrier defining the output opening for ejecting the packaging material. Thanks to the motorization of the packaging material production apparatus, the same can provide in shorter times larger amounts of packaging material compared to the manual packaging material production apparatus described above. An automatic packaging material production apparatus being equipped with a respective control electronics is furthermore able to produce predefined packaging material units from a predefined amount of original material according to predefined control processes or program sequences. By this, the amount of provided packaging material and the amount of consumed raw material can be optimized and controlled.
It can be calculated for example after which number of packages possibly being filled with a known or appreciable number of packaging materials a new paper strip roll is needed by the automatic packaging material product apparatus.
A different automatic product apparatus for packaging material is described in US 2007/0117703 A1. A roll wound on a spool at this apparatus serves as paper supply, the roll being unwound at the outer side. When a particularly large paper strip supply is desired, a roll with larger diameter can be chosen. It is thereby unfavorable that larger rolls come along with a greater weight by which the reloading is very demanding. In addition, the problem during operation, particularly during a fast production of large amounts of packaging material, is that the supply roll is rotating with great velocity. Because of the turning supply roll, paper jam and/or ripping off of the paper strip can occur especially during ramp up or during breaking of the automatic packaging material forming unit. When such an error is occurring, its trouble shooting is connected to a greater, undesired time effort.
An automatic packaging material apparatus and a facility with packing stations comprising the automatic packaging material production apparatuses discloses U.S. Pat. No. 6,981,489 B2. The packing stations (for example shown in
The accompanying drawings, which are incorporated herein and form a part of the specification, illustrate the embodiments of the present disclosure and, together with the description, further serve to explain the principles of the embodiments and to enable a person skilled in the pertinent art to make and use the embodiments.
The exemplary embodiments of the present disclosure will be described with reference to the accompanying drawings. Elements, features and components that are identical, functionally identical and have the same effect are—insofar as is not stated otherwise—respectively provided with the same reference character.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the present disclosure. However, it will be apparent to those skilled in the art that the embodiments, including structures, systems, and methods, may be practiced without these specific details. The description and representation herein are the common means used by those experienced or skilled in the art to most effectively convey the substance of their work to others skilled in the art. In other instances, well-known methods, procedures, components, and circuitry have not been described in detail to avoid unnecessarily obscuring embodiments of the disclosure.
An object of the disclosure is to provide an apparatus for the manual or automatic production of a packaging material or a packing station with such an apparatus, being equipped with a great reliability and availability with, at the same time, low tendency of maintenance or errors and which can provide large amounts of packaging material fast from a paper strip material.
According to that, an apparatus for the manual or automatic production of a tube-like packaging material from a paper strip wound to a roll is provided according to exemplary embodiments. A tube-like packaging material can also be denoted as a three-dimensional packaging material. A three-dimensional packaging material can be brought from a two-dimensional, plane, strip-shaped original material, usually a paper strip roll, into a three-dimensional structure having at least a crumple hollow space for providing damping and cushioning functions. Such a crumple hollow space can extend in the longitudinal direction of the packaging material. It may also therefore be denoted as tube-like packaging material. A tube-like packaging material can for example, as described in DE 10 2012 018 867 A1, be formed with an imprint extending in the longitudinal direction of the packaging material, which is stabilizing the packaging material. An imprint, as described in DE 10 2012 018 867 A1 in detail, approximately in the transverse width of the packaging material, the packaging material has two crumple hollow spaces in transverse direction (right and left) adjacent to the imprint strips. The tube-like packaging material can be provided cushion-like at a front-sided or rear-sided end with a stabilization, for example an imprint or punching, extending over a majority or the entire transverse width in order to protect single packaging material units in the shape of a cushion against unfolding starting from the longitudinal end sides. Such a cushion-like packaging material unit can be provided with a longitudinal imprint or be free of longitudinal imprints. The entire content matter of DE 10 2012 018 867 A1 is included by reference. A tube-like packaging material with three-dimensional shape can also be embodied without stabilizing imprints (in the longitudinal or transverse direction), as laid out for example in DE 20 2012 009 025 U1, where a spiral-shaped tube is formed by the pullout from the inside of the packaging material, the tube being able to provide a sufficient damping or cushion function for a multitude of packaging goods by the stiffness of the paper material and the inner-sided hollow space. The packaging material can nearly be ripped off stabilized, for example imprinted, or without stabilization.
The paper strip wound up to a roll of the apparatus according to the disclosure for the manual or automatic production of a tube-like packaging material defines a roll longitudinal axis and forms an inner hollow space, starting from which the paper strip can be pulled off for forming the packaging material. A roll can for example be provided, whose axial length is at least half as great as its outer diameter and/or its axial length be twice as great as its outer diameter at maximum. In an exemplary embodiment, the ratio of axial length to outer diameter of the roll can be greater than 0.75, particularly larger than 1, and/or smaller than 1.75, particularly 1.5. The ratio of axial length and outer diameter of the roll can for example be about 1.25. In an exemplary embodiment, the inner diameter of the roll in condition as new is be greater than 1 cm, preferably larger than 5 cm, particularly preferred larger than 10 cm, and/or smaller than 25 cm, preferably smaller than 20 cm particularly preferably smaller than 17.5 cm. An inner diameter of a new roll can for example be about 16 cm.
The apparatus according to an exemplary embodiment of the disclosure for the manual or automatic production of a tube-like packaging material comprises a guiding chute with an opening for ejecting the packaging material from a roll being arranged in ejection position, wherein the guiding chute has an inner contour narrowing in ejection direction towards the opening. The apparatus further comprises a primary seating for at least partially circumferentially gripping a first roll and for holding the first roll in the ejection position.
The primary seating and the guiding chute can for example be formed as thin-walled plastic parts with a thickness of less than 5 mm, as described for the apparatus of DE 20 2012 009 025 U1 for the manual production of a spiral-shaped packaging material, whose entire content matter is included in the present application by reference. According to the disclosure, the apparatus further comprises at least a secondary seating for receiving of at least a second roll for reloading the apparatus. The secondary seating with the second roll is formed movably between a passive position and an active position. In an exemplary embodiment, a movement of the secondary seating is following a similar movement of the second roll being received in that. It shall be clear that the first roll and the second roll can be identical in condition as new or at least being formed essentially equal. The secondary seating can be formed similarly to the primary seating. The secondary seating can be formed at least partly for the circumferential gripping of the second roll and for holding the second roll in a provision position, wherein the provision position can be different from the ejection position. In a passive position of the secondary seating, the second roll is positioned outside the ejection position.
In a passive position of the secondary seating, an ejection of stock material, particularly the paper strip for forming a packaging material starting from the second roll, is not provided. In a passive position, the second roll can be positioned in an axial distance and/or a radial distance relatively to the guiding chute and/or its ejection opening, which is preferably as large as the axial length or the radial width of the first roll, respectively, particularly in a condition as new. In an exemplary embodiment, sufficient space between the guiding chute or its ejection opening and the second roll is provided in the passive position of the secondary seating so that the first roll can be, particularly is, hinged in an ejection position. The second roll can be taken with the secondary seating from a passive position into an active position particularly in that moment in which the first roll in the primary seating is substantially or entirely consumed.
The second roll can be arranged in the ejection position in an active position of the secondary seating. The secondary seating can for example take the position or similar position as the one that the primary seating has taken before. It is possible, that the secondary seating shifts, glides, rotates, slides or such at the position of the primary seating. According to an alternative embodiment of the disclosure, the second roll in the active position of the secondary seating is preferably exclusively movable under the influence of gravity. According to a second alternative of the disclosure, the second roll in an active position of the secondary seating can slide, glide, roll, fall or such into the primary seating with the aid of the rotational force or the own weight.
The apparatus according to an exemplary embodiment of the disclosure is thereby designed in such a way that the second roll is movable from the secondary seating into the primary seating without manual support that the second roll is arranged in the ejection position after the relocation or as a result of the relocation. In an exemplary embodiment, the second roll is moveable from the secondary seating to the primary seating in such a way that by the relocation from the secondary seating into the primary seating without manual help, the second roll takes a position relative to the guiding chute in axial direction in which the orientation of the axis of the second roll and the distance of the foremost front wall of the second roll in ejection direction relatively to the ejection chute and particularly its opening in such a way that the paper strip for forming the packaging material from the inner hollow space of the second roll may be drawable directly after and/or as a result of the relocation (as previously from the first roll). The roll, which is located in the ejection position in which the paper strip can be pulled off the inner hollow space of the roll through the guiding chute for forming the packaging material is for convenience denoted as “first roll”, wherein it is clear that the “first roll” can be a (former second) roll being displaced from the secondary seating into the primary seating.
According to an embodiment, the primary seating can have a shell body particularly from plastic particularly with a smaller wall thickness smaller than 5 mm. In an exemplary embodiment, the shell body of the primary seating is dimensioned with an inner diameter which is at least as great as the outer diameter of a roll designated for being loaded into the apparatus. In an exemplary embodiment, the inner diameter of the primary seating measures at least 20 cm, particularly less than 25 cm, particularly preferably at least 30 cm. In an exemplary embodiment, the inner diameter of the primary seating is smaller than 100 cm, preferably smaller than 50 cm, because the rolls with such a large outer diameter are unpractical to handle. A shell body can also have a different form than the half cylindric shape, for example a V-shape cross-section or a polygonal cross-section. It is also thinkable that the primary seating is formed by at least two struts extending in the direction of the injection direction on which rolls can lie. A primary seating can comprise several struts extending in ejection direction or perpendicular to the ejection direction, in order to at least partly grip a packaging material strip roll circumferentially. By that, a seating longitudinal axis can also be realized by a seating formed by rails and/or struts.
According to an embodiment of the apparatus for the manual or automatic production of a tube-like packaging material, the secondary seating is formed to at least partly circumferentially gripping a second roll. The secondary seating can be formed like the primary seating. For example, the secondary seating can have a second shell body. A second shell body can be separate from a second shell body or be formed single-pieced with a first shell body. The secondary seating can alternatively or additionally have additional rails and/or struts and/or a shape different from cylinder shape. In an exemplary embodiment, the secondary seating can have an essentially half-cylindric shaped shell body. The secondary seating, particularly the second shell body, can define a second seating longitudinal axis. The second seating longitudinal axis can be aligned in an active position of the secondary seating correspondingly, particularly flushing, to the roll axis of the second roll and/or be arranged particularly in the active position of the secondary seating correspondingly, particularly flushing, in the seating longitudinal direction of the primary seating, particularly of a shell body of the primary seating. The secondary seating can be formed form complementary to the primary seating. A second shell body can particularly be formed form complementary to the first shell body of the primary seating.
In an exemplary embodiment, the apparatus for the manual or automatic production of a tube-like packaging material comprises a first roll received in the primary seating and/or at least a second roll being arranged in the at least one secondary seating.
According to an exemplary embodiment the secondary seating comprises a magazine that holds at least one second roll. The magazine can for example hold two, three or more second rolls. In an exemplary embodiment, the secondary seating has a magazine that is arranged as tube magazine with two rolls arranged in axial direction behind each other, a box magazine, preferably with a radial direction, particularly the vertical radial direction, having second rolls around next or on top of each other, wherein particularly the second rolls in the box magazine are each arranged in a touching contact extending in the axial direction between two neighbored rolls in the radial direction, a rod magazine, a drum magazine, preferably with several seatings being turnable around a collective rotation center through which a drum rotation axis is extending, or such. It is thinkable that a magazine, particularly a box magazine, a drum magazine or such, are forming the primary seating and at least one secondary seating. In this way a revolution of the magazine for a drum magazine, comprising several seatings, for example six seatings, can take place in such a way that one of the seatings is always arranged behind the guiding chute in the ejection direction, wherein after the consumption of the paper strip roll the emptied seating can be pivoted away from the guiding chute of the ejection opening by a rotation of the drum magazine and another seating being filled with a roll can take the place and the new roll can take the ejection position. It is also thinkable that for example guiding chutes or guiding chute sections or such are arranged at the drum magazine at the single seatings independently from their position, wherein a rotation of the drum magazine can serve to move away an emptied seating (“primary seating”) from an ejection position and to provide the ejection position with a new roll provided seating (“secondary seating”).
According to an exemplary embodiment of the packaging material production apparatus, the secondary seating for reloading the primary seating is exclusively arranged by the influence of gravity, particularly relatively to a vertical direction, above the primary seating. The arrangement of the secondary seating particularly for reloading a primary seating can also be positioned only partly above the primary seating. According to a special embodiment, the secondary seating including the received rolls can be arranged completely above the primary seating in such a way that the secondary seating and the arranged roll can be arranged completely above the primary seating and a fresh roll eventually arranged in the primary seating. In an exemplary embodiment, the secondary seating can be arranged relatively to the ejection direction behind the primary seating. The secondary seating can for example be arranged above and behind the primary seating in such a way that the second roll from the secondary seating to the primary seating in the ejection direction.
According to an embodiment of the packaging material production apparatus, the secondary seating particularly for reloading the primary seating can be displaced in parallel at least partly laterally, particularly horizontally with regard to the ejection direction, relatively to the primary seating. In an exemplary embodiment, the secondary seating can be arranged neighbored to the primary seating for an at least partly horizontal or essentially horizontal reloading position in the horizontal direction transverse to the ejection direction. A drum magazine can for example be provided with a drum axis being displaced horizontally to the ejection direction and/or the seating longitudinal axis of the primary seating. It is also thinkable that for example a box or rod magazine can have a magazine extension in horizontal direction transverse to the ejection direction and/or the seating longitudinal axis of the primary seating. The second rolls of such a magazine are provided essentially horizontally next to each other. In an exemplary embodiment, a horizontally aligned box or rod magazine includes a push means, like a spring or such, and/or have a preferably slight tilting of 30°, 15°, 10° or 5° at the most relatively to the horizontal direction.
According to an embodiment of the packaging material production apparatus, the ejection opening and/or the ejection direction are tilted downwardly. The downward tilting can particularly be adjustable. It is clear that relatively to a floor surface in which the production apparatus is placed, a perpendicular of the room extending in the vertical direction can be defined as well as two room horizontals, wherein one room horizontal is orientated according to an orientation of the ejection direction and the second horizontal direction can be defined vertically to both, the perpendicular and the first room horizontal. The term downwardly or tilted downwardly is therefore to be understood in such a way that particularly the ejection direction needs to have at least one direction component in the vertical direction downwards, particularly in such a way that the ejection can take place under the influence or the support of the gravity acting on the paper material strip. In an exemplary embodiment, the ejection opening and/or the ejection direction has a tilting angle of at least 10°, at least 30°, or at least 45°. By the choice of the tilting angle the ejection velocity can be increased for example for a manual ejection apparatus. Depending on the arrangement of the apparatus and the ejection opening the tilting angle can be adjustable for a particularly ergonomic taking of the packaging material from the production apparatus. The secondary seating, particularly a reloading section of the secondary seating, can be arranged relatively to the first horizontal direction in a tilting angle, being equal to the tilting angle of the ejection. The secondary seating, particularly a reloading section of the secondary seating, can have a sliding angle relatively to the first horizontal direction being different from the tilting angle of the ejection opening and/or the ejection direction.
According to an embodiment of the apparatus, which is combinable with the previous, the apparatus has a retainer means which can occupy a retainer position, in which the retainer means inhibits the reloading of the apparatus, and that can occupy a passage position, in which the retainer means allows a reloading of the apparatus. In an exemplary embodiment, the retainer means can be realized as movable means, for example as bar, bolt, flap, hatch, or such. The retainer means can particularly be arranged between the primary seating and the secondary seating. In an exemplary embodiment, the retainer means is arranged in ejection direction between the secondary seating and the primary seating. In an exemplary embodiment, the retainer means in the retainer position is inhibiting the reloading of the primary seating and that the retainer means and the passage position allows the reloading of the primary seating by the second roll. With the retainer means it can be assured that a reloading of the apparatus, particularly the primary seating, by means of a second roll is avoided as long as the paper from the first roll for the production of packaging material is drawable. The retainer means ensures in other words that a second roll is not sliding into the for example primary seating which is still occupied by a partly consumed first roll that could lead to a paper jam. A retainer means can for example for a rod magazine, a flap or trap door be between the secondary seating and the primary seating, or a latch that is inhibiting a drum magazine from a rotation of the second roll in the ejection position. If the magazine of a kind of a tube magazine has rolls being aligned behind each other in axial direction, a retainer means can be formed for example by a latch, wedge, bar or such, which is arranged in the retainer position in the ejection direction between the secondary seating and the primary seating, and which in its passage position allows a gliding or sliding of the second roll into the primary seating in its passage position.
According to an embodiment of the apparatus for the manual or automatic production of a tube-like packaging material, the secondary seating has a reloading section, which is aligned relatively to the primary seating constant particularly operation conformingly immobile and elevated relatively to a primary seating and/or adjacent, particularly flushing, towards the primary seating and/or above the primary seating. In an exemplary embodiment, the secondary seating has a rear filling section in ejection direction A extending in the vertical direction downwards. In an exemplary embodiment, the filling section of the secondary seating extends until below the primary seating, preferably until below the front sided ejection opening of the primary seating. In an exemplary embodiment, the filling section of the secondary seating extends in the vertical direction from a lowest point below the ejection opening toward the highest point close or corresponding to the highest point of a front sided reloading section of the secondary seating. A bridge, curve or saddle-shaped transition area can be provided in the horizontal direction between the filling section and the reloading section. The reloading section of the secondary seating can for example lead to a primary seating in the ejection direction tilted downwards in order to allow a movement of the second roll of the primary seating. The filling section of the secondary seating can be tilted upwards against the ejection direction in order to allow a filling of the rear side of the apparatus. By shifting a roll in the direction of the ejection direction within the filling section, a roll can be fed into the reloading section of the secondary seating. The transition area between the filling area and the reloading area of the secondary seating provides a protection against injuries of the paper strip roll when trespassing from the upwardly tilted filling section into the downwardly tilted reloading section.
According to an embodiment of the apparatus for the manual or automatic production of a tube-like packaging material, the secondary seating is movable in such a way that the secondary seating is movable between an active reloading position for reloading the apparatus, particularly the primary seating, and a passive filling position for refilling at least one further roll in the secondary seating. In an exemplary embodiment, the secondary seating moves into an active reloading position for reloading, particularly of the primary seating, being elevated and/or being positioned upstream, adjacent or overlapping to the primary seating in the ejection direction. The passive filling position can particularly be provided to allow the refilling of a further roll or several further rolls into the secondary seating from a position in the ejection direction behind the apparatus. In this way, the filling staff is enabled to refill, while the packing staff is generating packaging material from the first roll held in the primary seating, the secondary seating so that the secondary seating can be supplied with a second roll before the entire paper material is removed from the first roll. In an active reloading position, the secondary seating is arranged in a position being elevated and/or being positioned upstream in the ejection direction, in a position being adjacent to the primary seating or being overlapping an axial direction to the primary seating. The passive filling position is displaced towards an active reloading position. In an exemplary embodiment, the passive filling position is lowered and/or displaced against the ejection direction towards the rear, particularly relatively to the primary seating. It shall be clear that the relative position denotation of the passive filling position of the active reloading station is mutually relating to one another. In an exemplary embodiment, the active reloading position is positioned upstream relatively to the passive filling position in the ejection direction and/or elevated in the vertical direction. The passive filling position is lowered relatively to the active reloading station in the vertical direction and/or displaced rearwards against the ejection direction. By that, the primary seating can serve as a reference point.
According to a further development, the apparatus for the automatic or manual production of a tube-like packaging material has a secondary seating being translationally, particularly telescopically, movable in or against the ejection direction. Alternatively, or additionally, the secondary seating can be pivotable around a transverse axis, extending transverse to the ejection direction in the horizontal direction (of a second horizontal direction). A first horizontal direction can be oriented correspondingly in the ejection direction. The primary seating and the secondary seating can be coordinated to each other in such a way, particularly dimensioned and/or aligned in such a way, that the secondary seating can move at least section-wise forwards and backwards within the primary seating, preferably telescopically. The secondary seating can be provided with a support apparatus, like a spring, preferably an air pressure spring, for the mass balance regarding the secondary seating. The support apparatus of the secondary seating preferably during a movement of the secondary seating in the vertical direction upwards, for example from its passive filling position in its active reloading position, particularly during a pivoting movement around the transverse axis, can at least in parts be a mass balance of the secondary seating and of the second roll(s) received in it.
According to an exemplary embodiment of the apparatus for the automatic or manual production of packaging material, the apparatus can have at least one sensor for capturing the presence or non-presence of a roll in the primary seating and/or the secondary seating. In an exemplary embodiment, only one sensor for capturing the presence or non-presence of a roll in the secondary seating is provided. The sensor for capturing the presence or non-presence of the roll particularly in the secondary seating can be coupled to the retainer means. With a sensor it can be tested whether at least one roll or at least two rolls are present in the primary seating and/or in the secondary seating, so that the apparatus, particularly the secondary seating, can be refilled before the entire paper strip material, particularly from the primary seating is converted into packaging material, the apparatus therefore being emptied completely.
According to an exemplary embodiment of the apparatus for the manual production of a spiral tube-shaped packaging material according to the disclosure, the apparatus is free from a drive, like an electric drive, for feeding the packaging material and/or the paper strip. According to this embodiment, the apparatus is free of motor, like an electro-motor, driven feed means, like feed rollers. The apparatus of this embodiment is furthermore free of particularly motor, like electro-motor, driven separating means, like a cutting apparatus, for example scissors, a guillotine or such.
According to an exemplary embodiment of the apparatus for the automatic production of a packaging material, the apparatus comprises feed means, like feed and/or forming rollers, for feeding the packaging materials and/or the paper strip as well as a particularly electric drive for driving these feed means. The apparatus according to this embodiment can have if applicable an electric driven separating means, like a cutting apparatus, for example scissors, a guillotine, a rotation cutter or such, for cutting off a cushion material unit, like a cushion product, from the tube-like packaging material.
The disclosure also relates to a packing station with an apparatus for the manual or automatic production of a tube-like packaging material is described in the above embodiments or further developments. The packing station further comprises a frame on which the apparatus is mounted. In an exemplary embodiment, the frame has a front side facing the packing staff, with a shelf space, wherein the opening of the apparatus is arranged at the front side of the frame particularly above the shelf space. Additionally, or alternatively, the frame can have a rear side to be averted the packing staff, wherein the secondary seating is arranged in a preferably tilted and/or backwardly displaced filling state to the rear side, preferably behind the rear side and/or downwards, preferably at or under the frame top side on which preferably the apparatus can be fixed. The frame can for example be mounted to a wall, be mounted hanging from the ceiling, or be arranged standing on the ground. Combinations of the mounting of the frame or of frame components, respectively, in a room are thinkable.
In the following depictions of exemplary embodiments same or similar reference numerals are employed for the same or similar components. An apparatus according to an exemplary embodiment of the disclosure for the manual or automatic production of a tube-like packaging material is in general denoted with reference numeral 1. A packing station is denoted with reference numeral 100 in the following. For simplicity reasons, the depiction of embodiments of detailed motors or motor-driven feed or forming rollers or such Figures are left out. It is hereby referenced to DE 10 2009 015 855 A1, EP 2 711 167 A1, EP 2 711 168 A1 and DE 10 2005 053 319 A1, whose entire content shall be included into the application by reference. The apparatus 1 according to the disclosure for the manual or automatic production of a tube-like packaging material from a paper strip coiled to a roll 11, 12 comprises as main components a guiding tube 5, a primary seating 3 positioned behind in the ejection direction, and a secondary seating arranged above and/or behind that. As laid out in the depictions of embodiments in detail, the secondary seating can for example be realized as a part of a magazine, for example a tube magazine 20 extending lengthwise with rolls arranged behind each other, as box magazine 40 with rolls stacked on top of each other or as drum magazine 30 with rolls supported around a drum axis T turnable in the separate seatings.
In the following, the packing station 100 with a manual packaging material production apparatus 1 having a tube magazine 20 is described in
The first horizontal direction shall be oriented according to the ejection direction A of the apparatus 1. The ejection direction A is set by the form and arrangement of the ejection opening 7, which is provided in the center of the ejection and guiding chute 5 of the apparatus 1. The ejection direction A is tilted downwards by a tilting angle α against a first horizontal direction H1. The primary seating 3, which is formed in the exemplary embodiment examples by a half cylindric shell body 53, in which a first roll is supported, extends in the ejection direction A behind the ejection and guiding chute 5.
The seating longitudinal axis L1 of the primary seating corresponds to the first roll longitudinal axis L1 of the first roll 11. It shall be clear that slight radial displacement between the roll longitudinal axis L1 and the seating longitudinal axis L1 is possible in the range of possible tolerances in the radial direction to the longitudinal axis. In an exemplary embodiment, the first roll 11 abuts with its frontal front side at the inner, chute-shaped wall of the guiding chute 5, preferably with a radial circumference outer side of the roll 11.
The paper strip forming the rolls 11 can be stripped from the inner side of the roll 11 through the guiding chute 5 and its ejection opening 7, wherein the spiral tube-shaped packaging material is formed, which can be ripped off the ejection opening 7 for forming a single packaging material unit. The shell body 53 and the guiding chute 5 can be made thin-walled particularly from plastics. The guiding chute 5 can be mounted with a plug connection, like a bayonet connection, detachable or not detachable at a first shell body 53.
A secondary seating 21, which is also realized here as a shell body 23, is provided in the ejection direction A behind the first shell body 53 of the primary seating 3. The second shell body 23 of the embodiment shown in
In an exemplary embodiment, the second shell body 23 has a slightly smaller inner diameter than the first shell body 53. The inner diameter of the second shell body 23 can for example measure by one wall thickness or more, less than an inner diameter of the front, first shell body so that the second shell body 23 can be arranged at least partly inside the first shell body and can be displaceable translationally, and in an exemplary embodiment, telescopically, within the first shell body 53 (not depicted in detail). A bar 61 or a retainer means can be provided between the primary seating 3 provided by the first shell body 53 and the secondary seating 21 provided by the second shell body 23, which inhibits a second roll in the primary seating 21 to shift unhinderedly into the ejection position at the primary seating. The retainer means 61 is realized as bar in
The secondary seating 21 is arranged in ejection direction A behind and in vertical direction V above the primary seating 3 so that a not further depicted second roll from the secondary seating 21 can glide under the major influence of gravity from the secondary seating 21 into the primary seating 3. In order to allow a simple gliding or sliding of a roll from the secondary seating 21 into the primary seating 3, the seating longitudinal axis L2 of the secondary seating 21 and L1 of the primary seating 3 can be arranged correspondingly, particularly flushing, to each other. The apparatus 1 can for example have a for example capacitive sensor 70 at the secondary seating 21, which captures a roll is located in the secondary seating 21. If, as in
Alternatively, or additionally, also different signals can be generated, for example an acoustic signal and/or a signal to a central control unit, which for example can be informed about the consumption of paper material strip rolls of a single or each single production apparatus within a logistic center. The (not further depicted) control electronics can be connected to retainer means 61 where a further (not further depicted) sensor can be provided in order to capture the reloading procedures of the apparatus. If the apparatus, as for the embodiments explained later, has a magazine 30, 40 with a capacity for more than one second roll 12, by the use of one or more sensor 70, at one or more secondary seatings and/or a reloading sensor, for example a retainer means, can be monitored, if or how many rolls are available in the production apparatus. In an exemplary embodiment, the central control unit and/or the control electronics include processor circuitry that is configured to perform one or more functions and/or operations of the central control unit and/or the control electronics.
A second supporting beam 67 extends underneath the shell body 23 of the secondary seating 21. The second supporting beam 67 extends mainly in the direction of the support longitudinal axis L2 of the secondary seating 21. The second supporting beam 67 supports itself at the second fixture 66 being mounted at the top side 109 of the frame 101. Instead of a fixture consisting of two fixtures 64, 66, also a single fixture can be provided. The in the ejection direction A front-sided end of the second supporting beam 67 is supported at the first supporting beam 65 via a hinge 68. The hinge 68 connecting the primary seating 3 with the secondary seating 2 allows a translatory movement of the secondary seating 21 relatively to the primary seating 3 in the direction of the first seating longitudinal axis L1. The hinge 68 between the primary seating 3 and the secondary seating 21 also allows a pivoting movement of the secondary seating 21 around a transverse axis Q relatively to the primary seating 3.

It is alternatively also thinkable to use a rod magazine on which rolls are arranged to each other not automatically perpendicular in the vertical direction, but in the vertical direction above each other, however not perpendicular but displaced in a zigzag manner. In this way, more rolls can be accommodated in a rod magazine than in a box magazine 40 with the same height in the vertical direction V, for the same vertical height but greater width in the horizontal direction H2.
As shown in
By means of the holding fixture 60, the box magazine can be brought from the active reloading position (4D) into a filling position pivoted backwards for example by 90° around the transverse axis Q of the hinge 68 of the holding fixture 60 (
Deviating from the previous embodiments, the apparatus 1 for the production of a packaging material according to the
The exemplary embodiments in
For this purpose, a sensor (not depicted), like the sensor 70 described above, can be provided in the rear-sided area of the secondary seating 21, for example in the area of the rear-sided shell body 23B, in order to notice a presence or non-presence of a second paper roll 12 at this position. A sensor like the sensor 70 described above could generate a paper roll need signal at the rear-sided end of the reloading section 22 for processing by the control electronics, for example by generating a need signal by means of the lights 71.
The holding fixture 60 of an exemplary embodiment of an apparatus 1 shown in
In an exemplary embodiment, the filling section 24 extends until behind the rear side 105 of the frame 101 until underneath the ejection opening 7 and/or the top side 107 of the frame 101 of the packing station 100. In an exemplary embodiment, at the rear-sided, lower filling end of the filling section 24, a holder is formed as an edge 26 and/or flap which prevents a slip out of new second rolls 12 from the filling section. Securing clamps 27 or other securing means can be provided in the filling section 24, which are provided in the vertical extension of the filling section 24 at least section-wise in order to prevent a rearward tilting out of one or more rolls from the filling section 24. Securing clamps 27 can for example be provided to each other at the clamp section in distances smaller than the axial length of a roll 12.
For filling the apparatus 1, filling staff can introduce or insert, respectively, fresh rolls into the filling section 24 from the rear side 105 of the frame 101. One or more rolls can be put from a lower filling position upwards to the refilling section 22, manually, by means of tools or motor-driven feed means, for example a conveyor, or such.
It can be seen from
The telescopic ability of the shell body sections 23a, 23b allows, dependent on the width of the frame 101, to statically adjust the axial length of the secondary seating 21. In an exemplary embodiment, the rear-sided shell body 23b is introduced section-wise into the front-sided shell body 23a. For this purpose, the front-sided shell body 23a and the rear-sided shell body 23b have the same cross-sectional shape with different cross-sectional width, for example a half-cylindric or V-shaped cross-section shape with different vastness (inner diameters). An alternative embodiment of two or more longitudinal struts forming the secondary seating can be designed in such a way that struts with the same length extension direction (L2) being displaced in the axial direction and in the radial direction to each other are provided so that overlapping areas between the front-sided and rear-sided struts comply with the overlapping area of both of the shell bodies 23a, 23b.
It is also thinkable that the front-sided area of the one or several shell bodies 23 of the reloading section 22 overlaps with the rear-sided area of the shell body 53 of the primary seating 3 in the axial direction.
In an exemplary embodiment, in order to avoid a locking of the rolls 11, 12 at the transition between different seating sections, a flushing arrangement of the different sections to each other is used, or an arrangement on which seating sections being arranged further rear-sided in the ejection direction A are extending section-wise within a seating section lying before in the ejection direction. The rear-sided shell body section 23b of the embodiment shown in
By activating a lever 72, the bar 62 can be driven in the radial direction outwardly until a passing position in which the same is located outside the roll area of the secondary seating 21, so that it is not a barrier for the roll 12 anymore. The bar 62 can for example be moved by a mechanical activation, such as a lever 72, mechanically from the retainer position into the passing position and when releasing the lever 72, the spring returns pre-loaded into the retainer position. It is also possible that instead of a manual, a mechanical activation takes place by a (not further depicted) control button or a controlled electric activation, by which an electronic actuator of the retainer means, such as a bar 62 or the previously-described bar 61, is moved between the retainer position. An electronic activation by means of a reloading button can, at the same time, be connected to the control electronics and the button press can be evaluated as a signal for the order of a further roll for filling the secondary seating.
