Description

SYSTEM FOR CONVERTING A WEB-SHAPED STARTING MATERIAL INTO PACKAGING BAGS

The present invention relates to a system for converting a sheet starting material into packaging bags. A web-shaped starting material defines a longitudinal direction of the web and expands between two opposite longitudinal edges. The web-shaped starting material preferably consists of paper or cardboard.

Packaging bags, a packaging material web and packaging material blanks are known from DE 10 2020 114211 Ai. Such packaging bags, etc. are used in the packaging industry to pack objects, especially shipping items, in particular to protect them from damage during shipping.

Various systems are known for forming packaging bags, a packaging material web and packaging material blanks for receiving objects such as shipping items from strips of packaging material.

GB 1,067,166 describes a system for packaging objects. The system includes a supply roll of a weldable web material such as polyethylene or polypropylene. Starting from the supply roll, the web material is unrolled downwards via guide rollers and introduced between a forming channel delimited by side walls transversely to the longitudinal direction of the web and an insertion channel extending inside the conveying channel. The insertion channel is dimensioned for a specific type of similar shipping item. In the course of the insertion channel, the packaging material web, which is open at the top, can be filled with objects such as shipping items from above; the inserted objects are pushed out of the channel pair in the conveying direction into a packaging material tube using a slider. At the end of the insertion channel, the edges of the web material are folded inwardly by a pair of folding lips and sealed with a first punch to form the packaging material tube. A second punch arranged further downstream of the conveyor stream seals the front and rear edges of the tube in the longitudinal direction of the web and includes a cutting edge for separating packaging bags. From an ecological point of view, it is desirable to avoid weldable plastic material sheets. The supply roll positioned at the top can only hold a very limited amount of the raw material web. Furthermore, due to its weight, it is heavy and takes a lot of time to load. Forming using a pair of channels has also proven to be a frequent cause of web breaks, which is disruptive to the continuous production of packaging material webs and sections thereof. The channel pairing is sized to fit specific items, so they are not flexible for packaging different objects of variable shape is suitable, but different channel pairs must be provided for different object types and the system must be converted with great effort. It has also been shown that the longitudinal edges of the packaging material web protruding in the area of the channel pair pose a risk of injury. Using the slider is tiring for users and takes time. If a user inserts items that are too large, they or the packaging material web may be damaged when using the slider. The facility also has a large footprint, which is undesirable for small logistics centers.

It is an object of the invention to overcome the disadvantages of the prior art, in particular to provide a system for converting a web-shaped starting material into packaging bags, which is easy, safe and reliable to handle and suitable for packaging a wide variety of objects while requiring little space. This task is solved by the subject matter of the independent claims.

Accordingly, a system is provided for converting a web-shaped starting material, wherein the starting material defines a longitudinal direction of the web and extends between two longitudinal edges opposite in the direction of the web width. In particular, the starting material includes, in particular predominantly, d. H. at least 75%, in particular at least 80%, preferably at least 90%, paper or cardboard or consists of it.

Sheet material or sheet material, such as the starting material, has a longitudinal direction of the sheet. The sheet material preferably has a constant sheet/material thickness. Web-shaped material generally expands in the web width direction transversely to the web longitudinal direction and, when viewed transversely to the web direction, in particular has a constant width. In the web width direction, the web-shaped material has opposing longitudinal edges. In the web width direction, the packaging material web ends at a longitudinal edge or at a longitudinal edge extending in the longitudinal direction of the web. For example, the web-shaped starting material has a width of at least 200 mm and in particular of at most 2000 mm. For example, the width is approximately 500 mm. Web-shaped material generally has much larger dimensions in the web longitudinal direction than in the web width direction, for example the extent of the web material in the web longitudinal direction can be at least 20 times, at least 50 times, at least 100 times, at least 1000 times larger than in the web width direction . Sheet material generally has much larger dimensions in the sheet width direction than in the thickness direction, for example the extent of the sheet material in the sheet width direction may be at least 20 times, at least 50 times, at least 100 times, at least 1000 times larger than the sheet /-Material thickness. Optionally, at least one longitudinal edge strip adjacent to a longitudinal edge is provided at least in sections with a cold-sealable adhesive. The adhesive width of the with The longitudinal edge strip provided with cold-sealable adhesive can be at least 10 mm and in particular at most 300 mm, 250 mm or at most 200 mm. For example, both opposite longitudinal edges can be provided with cold-sealable adhesive.

The web-shaped material is preferably formed predominantly or entirely from a cellulose-based material. In particular, the web-shaped material can be formed from paper, such as recycled paper, and/or cardboard, in particular corrugated cardboard. A web-shaped material, in particular made of paper or cardboard, in particular corrugated cardboard, is preferably provided. The material web can be made from paper, such as recycled paper, and/or 100% recyclable paper, which can be made without chemical ingredients. Recycled paper is in particular paper materials with a small proportion (less than 50%) of paper material containing fresh fibers. For example, paper materials that contain 70% to 100% recycled paper, especially based on waste paper, are used. The recycled paper in the context of this invention can be paper material which can have a tensile strength index along the machine direction of at most 90 Nm / g, preferably a tensile strength of 15 Nm / g to 60 Nm / g, and a tensile strength index across the machine direction of at most 60 Nm / g can have, preferably a tensile strength of 5 Nm / g to 40 Nm / g. To determine the tensile strength or the tensile strength index, a standard DIN EN ISO 1924-2 or DIN EN ISO 1924-3 can be used. Additionally or alternatively, a recycled paper property or waste paper property can be characterized by the so-called bursting resistance. A material in this sense is recycled paper with a burst index of at most 3.0 kPa*m ^A 2/g, preferably with a burst index of 0.8 kPa*m ^A 2/g to 2.5 kPa*m ^A 2/g. The DIN EN ISO 2758 standard is used to determine the burst index. Furthermore, the packaging material has a mass per unit area of in particular 40 g/m ^A 2 to a maximum of 140 g/m ^A 2. The web-shaped starting material can be in the form of a roll of material web or a zigzag-folded stack of packaging material, which is also referred to as a fanfold stack.

The system according to the invention comprises a forming device for continuously forming the web-shaped starting material into a material web with a receiving cavity extending in the longitudinal direction of the web. The forming device is preferably designed and set up to transform the, in particular originally flat, web-shaped starting material into a material web with a V- or U-shaped cross section. Preferably, the receiving cavity of the material web has an insertion opening extending in the longitudinal direction of the web. In particular, the receiving cavity is delimited by a pocket base formed opposite the insertion opening and laterally by protruding wings of the material web. The material web can, for example, be formed with a V-shaped cross section. The forming device can, for example, be designed to transform an originally flat web-shaped starting material by at least one wing, which extends along a first (for example right in the direction of conveyance) or second (for example on the left in the direction of conveyance) longitudinal edge is bent or folded towards the other wing. Alternatively, the material web can be formed with a U-shaped cross section. The forming device can be designed to bend or fold opposite wings on both opposite longitudinal edges of the originally flat web-shaped starting material toward one another to form a spine extending along the center of the web material. In the system for converting the web-shaped starting material, the forming device is preferably arranged downstream of a feed device in the conveying direction.

In particular, the forming device comprises at least one folding means, such as a folding roller, which can be or is brought into contact with the material web, such as a rolling contact, a sliding contact or the like. The folding means can in particular be designed and set up to press against the material web. The folding means can be arranged relative to at least one other means determining the conveying path of the web-shaped starting material or the material web, in particular at least one upstream, downstream, in relation to the conveying direction to the right or left relative to the folding means, that the folding means together with the at least one other means causes a deformation of an originally flat web-shaped extension. In particular, the at least one other means determining the conveying path of the web-shaped starting material or the material web can also be brought into contact with the starting material or the material web. The forming device comprises at least one folding means, such as a folding roller, which pushes against the material web transversely to the longitudinal direction of the web between the opposite longitudinal edges in order to introduce two wings protruding from a pocket base into the web-shaped starting material. Preferably, the folding means pushes against the material web in the web width direction, particularly centrally between the opposite longitudinal edges.

Furthermore, the system according to the invention for converting a web-shaped starting material into packaging bags comprises a loading device with a loading opening through which shipping items or shipping goods can be inserted in a loading direction into the receiving cavity of the V- or U-shaped material web. Preferably, the loading direction is oriented transversely, in particular perpendicular, to the conveying direction in the area of the loading device. The loading device can include a guide in order to support the V- or U-shape of the material web in the area of the loading device, in particular on the base of the pocket and/or on at least one wing. The loading device is designed and set up in particular to keep the material web open in a trough shape in the area of the loading opening. In the system for converting the web-shaped Starting material, the feeding device is preferably arranged downstream of the forming device in the conveying direction.

According to a first aspect of the invention, which can be combined with the second aspect and/or the other aspects, the loading opening is surrounded by a frame which defines a clear width and a clear length, which limit the dimensions of the usable shipping items. Preferably, the frame completely surrounds the loading opening. The clear length is preferably oriented in the conveying direction and, if necessary, the longitudinal direction of the web. The clear width is preferably oriented transversely to the conveying direction and, if necessary, the web width direction. In particular, the loading device is covered by the frame at least on the side provided with the loading opening, with the exception of the loading opening. It may be preferred that the loading opening has a clear width which essentially corresponds to the width of the pocket base. In particular, in the area of the loading device, the longitudinal edges of the material web, in particular the wings protruding from the base of the pocket, are covered by the frame. In particular, the frame is coordinated with a guide for the material web in the loading device, the forming device arranged upstream of the loading device, a conveying device, a sealing device and/or a separating device in such a way that the longitudinal edges of the material web in the area of the loading device are covered by the frame. In particular, the frame forms a panel which is designed and set up to allow loading access for inserting shipping items exclusively into the receiving cavity of the material web and/or to prevent access to the longitudinal edges of the material web in a covering state. The width of the frame is larger than the clear width, in particular at least 50% larger than, preferably at least twice as large as, the clear width. The length of the frame is greater than the clear length, in particular at least 10% greater, preferably at least 25% greater. The length of the frame is preferably not greater than three times the clear length, in particular not greater than twice the clear length.

The frame can be used to ensure secure access for particularly manual insertion of shipping items into the material web. By using a frame, the risk of injury due to the protruding longitudinal edges as well as unintentional deformation of the wings can be eliminated. Furthermore, the frame can be used to ensure that only those shipping items can be inserted into the material web to be formed into packaging bags whose shape and size allow them to be subsequently picked up in a packaging bag surrounding the shipping item.

In a preferred embodiment of the first aspect of the invention, the frame is fixed in place on the loading device. Alternatively or additionally, the clear width and the Clear length fixed in a dimensionally stable manner. In particular, the frame is formed in one piece, preferably solidly, or from rigid frame parts that are firmly connected to one another. The frame can, for example, be formed from at least one sheet, at least one shell, at least one plate or the like.

According to another embodiment of the first aspect of the invention that can be combined with the previous embodiments, the frame has guide surfaces, such as guide plates, which are opposite to the conveying direction and which delimit the loading opening. The guide surfaces form opposite longitudinal edges, with the guide surfaces in the area of the longitudinal edges being rounded with respect to the loading direction, in particular the guide plates being shaped with a bend. The longitudinal edges limit the loading opening in the web width direction. The clear width can be determined by the, preferably constant, distance between the longitudinal edges, with the longitudinal edges preferably being arranged parallel to one another. The guide surfaces preferably extend in the loading direction from a front side of the frame into the loading device, in particular in the direction of the pocket base and/or at least one guide surface opposite the loading opening. The extension length of the guide surfaces in the loading direction is preferably chosen to correspond to the depth of the wings formed by the forming device. It may be preferred that the extension length of the guide surfaces in the loading direction is not greater than a depth of the wings of the V- or U-shaped material web in the area of the loading device, in particular not greater than three-quarters of the depth, preferably not greater than half the depth , particularly preferably not larger than a third of the depth. It may be expedient for the guide surfaces to be matched to the forming device in such a way that the guide surfaces protrude at least in sections into the receiving cavity of the material web to be formed by the forming device. Using guide surfaces, users can safely place shipping items into a receiving cavity in a web of material that is to be formed into a packaging bag. It may be preferred that the guide surfaces, in particular the guide plates, are designed separately from the frame. Particularly preferably, on the one hand, the frame and, on the other hand, the guide surfaces are mounted or can be mounted separately from one another on the loading device. In particular, the frame and the guide surfaces, such as guide plates or the like, are in two parts. Guide surfaces, such as guide plates, can be designed to be adjustable in size or interchangeable. The system therefore ensures a high level of flexibility and quick adaptability to different sizes of mailing bags. This is particularly advantageous if the frame's clear width or its clear length can be exchanged and/or adjusted, so that the guide surfaces, in particular the guide plates, can remain.

According to a further development of the system with guide surfaces, it can be provided that on the inside of the loading device in the area of the guide surfaces transversely to the conveying direction opposing guides for opposing wings, in particular longitudinal edges, of the material web with a U-shaped cross section, such as guide plates, guide rollers and / or guide rollers. The guides are arranged upstream in the conveying direction and/or in the area of the loading opening. In particular, the guide surfaces can be designed as guide plates or the like and set up to guide the inner sides of the wings defining the receiving cavity in the area of the loading device in the conveying direction. Additionally or alternatively, the guides can have guide plates which guide the outside of the wings forming the outside of the packaging bags to be formed in the area of the loading device in the conveying direction. Upstream of the feed opening, the guides can have funnel-like insertion sections for one (right or left) of the wings. Upstream of the feeding device, the guides can comprise a funnel-like transfer section for the common supply of both wings, in particular both longitudinal edges, to a conveying device, sealing device and/or separating device provided downstream of the loading device.

In a preferred embodiment of a system according to the invention, the frame is detachably connected to the loading device. Preferably, the system comprises several frames with different frame sizes, one of the several frames being attachable to the loading opening and the other of the several frames being storable in a magazine or the like. The plurality of frames preferably have different frame sizes that differ from one another in their clear width and/or clear length. A system with an interchangeable frame and/or an adjustable frame size can be easily adapted to different sized packaging bags and/or shipping items. Alternatively or additionally, the frame has at least one adjusting means for adjusting the clear length and/or the clear width. To achieve greater flexibility, the clear width and/or the clear length can be designed to be adjustable. The adjusting means can be adjusted in particular in predetermined grid steps. In particular, the system can have a frame with a fixed clear width and an adjusting means for adjusting the clear length. Alternatively, the system can have a frame with a fixed clear length and an adjusting means for adjusting the clear width. The actuating means can preferably have an actuating means actuator, such as an in particular electromechanical actuating drive, which is designed and set up to approach a clear length and/or clear width to be set, and a control device for actuating the actuating means actuator. Furthermore, the system can have an operating device for determining the clear length and/or clear width to be set, which is connected to the control device in terms of signal transmission. It may be preferred that a size, in particular a length and/or depth, of the packaging bag to be formed is adjustable depending on the clear width and/or clear length of the frame. For example, the control device and/or the Operating device according to signal transmission can be designed with a separating and/or sealing device and/or conveying device for adjusting a size, in particular length and/or depth, of the packaging bag to be formed.

According to one embodiment of a system according to the invention for converting a web-shaped starting material web into packaging bags, the loading device defines a guide surface for the base of the bag, which limits the dimensions of the usable shipping goods in the loading direction. The guide surface is preferably arranged opposite the loading opening in the loading direction. The guide surface can extend into the forming device. The loading device and, if applicable, the forming device define the guide surface, in particular for the bottom of the pocket. Preferably, the guide surface is designed to guide and/or support the V- or U-shaped formed material web in the area of the pocket base and/or between opposite wings of the material web. The guide surface can be designed in particular as a stop for objects inserted or usable in a loading device, such as shipping items.

According to a development of the system with a guide surface opposite the loading opening in the loading direction, the guide surface can be defined by at least one counter bearing, in particular at least one counter bearing roller or a sliding surface, corresponding to at least one folding means, such as folding rollers, in particular the second folding roller. It may be preferred that the guide surface implements, at least in sections, a means determining the conveying path of the web-shaped starting material or the material web, which can be or is brought into contact with the starting material or the material web. A deflection axis defined by the deflection, in particular the deflection roller, can be aligned transversely, in particular perpendicular to the conveying direction along the guide surface and/or offset from the guide surface. With the aid of at least one counter-bearing roller, in particular several counter-bearing rollers, and/or at least one sliding surface, in particular several sliding surfaces, in which case in particular counter-bearing rollers and sliding surfaces can be provided alternately in the conveying direction, a reliable counter-bearing can be provided on the guide surface for supporting the base of the pocket and, if necessary, in the receiving cavity or used items, such as shipping items.

The system can be at least partially deactivated by the safety sensor. The safety sensor is preferably designed and set up to detect whether at least one object, such as an object, for example a shipping item, and/or a person, such as their hand, arm or other body part, is in the area of the loading opening. In particular, the safety sensor can be designed to detect objects in an area located at the edge of the loading device and spanning the loading opening. Preferably, the safety sensor is designed to cause the system to be at least partially deactivated if the safety sensor detects an object arranged in the area of the loading opening, such as a body part, such as a finger of a person engaging in the loading opening, or a shipping item that has not been completely received in the receiving cavity , for example a shipping item that is not in the correct orientation, is not inserted deep enough, or is too large. The integration of a safety sensor into a system according to the invention allows particularly safe handling.

According to a preferred embodiment of the second aspect of the invention, the system comprises at least one conveyor device that can be deactivated by the safety sensor. A conveyor device can be designed and set up to convey the web-shaped starting material formed in the forming device, in particular from the loading device. In particular, only the conveying device can be deactivated by the safety sensor. It may be preferred that in the system further system components, such as a feed device, clamping means, deflection, forming device, marking device, sealing device and/or separating device, are operated and/or actuated depending on the conveying device, in particular these further system components being exclusively in an active state the conveyor device are operated.

According to a preferred embodiment of the second aspect of the invention, the system comprises at least one retraction device, clamping device, deflection, forming device, marking device, sealing device and/or separating device which can be deactivated by the safety sensor and which is or are connected to the safety sensor in terms of energy and/or signal transmission. A feed device can be designed to pull the web-shaped starting material from a material web supply, for example a zigzag-folded supply stack, which can also be referred to as a fanfold stack, or from a supply roll. A clamping device can be implemented, for example, by a support roller. A deflection can be realized, for example, by a deflection roller for guiding the web-shaped starting material from the feed device along the deflection to the forming device, in particular along a deflection angle of at least 10°, in particular at least 6o°, preferably at least 90°, and possibly not more than 180° . A marking device, such as a printer, a label adhesive, or the like, can be designed and set up to apply or attach at least one visually visible marking to an outside of the packaging bag and/or the web-shaped starting material. A sealing device can be designed and set up for sealing at least one transverse strip and/or a longitudinal strip of the formed web-shaped starting material, in particular for forming a packaging bag. A separating device can be designed and set up to separate a packaging bag from the starting material web along a transverse strip. Optionally, the system can include one or more further components or components that can be deactivated by the safety sensor.

Alternatively, the position sensor can comprise an ultrasonic sensor, a mechanical sensor such as a slide, a feeler, a gauge, a knob button or the like, or an X-ray sensor. The position sensor is directed at at least one reference area on an inside of the loading device in the area of the loading opening. In particular, the position sensor is directed towards an inner edge of the loading opening. The position sensor is designed to detect whether the reference area is exposed or at least partially (or even completely) covered by a shipping item. The position sensor can be connected to at least one signal generator, such as an optical signal generator, for example an indicator light, or an acoustic signal generator, in order to activate the at least one signal generator, in particular to trigger it, if the reference area is at least partially covered. Alternatively or additionally, the position sensor can be connected to at least one component of the system, for example a control unit, a conveyor device Sealing device and/or a separating device. In particular, the system can be designed and set up to prevent actuation of the conveying device, the sealing device and/or the separating device when the position sensor detects at least partial coverage of the reference area. The position sensor can be used to ensure that no objects, such as shipping items, are placed in the receiving cavity and then further conveyed that are too large in the loading direction for the achievable shipping bag size or are not inserted deep enough or are not inserted correctly, such as for example, are inserted crookedly and at least partially protrude outwards. If a user mistakenly places an item that is too large into the loading opening, they will be notified of its incompatibility with the system so that the item can be removed from the receiving cavity and the production process can continue. In this way it can be ensured that no material jams or the like occur in the device.

In an embodiment of the third aspect of the invention, the position sensor, in particular the optical sensor, is arranged in the feed direction in the feed opening. Preferably, the at least one position sensor is fixed in place on a frame of the system, in particular the loading device. In particular, the position sensor can be arranged in the conveying direction between the forming device and the loading device. By arranging the position sensor in the feed opening, a collision of the position sensor with objects to be inserted, in particular shipping items, can be ruled out.

According to another embodiment of the third aspect of the invention, which can be combined with the previous one, the position sensor, in particular the optical sensor, is arranged on the inside of the loading device. The position sensor is aimed at the receiving space of the material web with a V- or U-shaped cross section. The position sensor is preferably aligned in the direction of conveyance.

The lidar sensor can preferably be designed as a two-dimensional lidar sensor or as a three-dimensional lidar sensor. The use of a three-dimensional lidar sensor is particularly suitable for a relatively wide shipping bag design, but for a relatively narrow shipping bag it has been found that a two-dimensional lidar sensor is sufficient. Preferably, the measuring device is connected in terms of signal transmission to a control unit, a conveying device, a sealing device and/or a separating device of the system. The system, in particular the control unit, the conveying device, the sealing device and/or the separating device can be designed to treat the material web depending on the at least one piece size determined by the measuring device. With the help of a measuring device, the production of shipping bags from the web-shaped starting material can be optimized by the system, for example with regard to the production speed as well as with regard to an optimized Design of the shipping bags, in particular their transverse stripes and/or longitudinal stripes.

According to a preferred embodiment of the fourth aspect of the invention, the measuring device comprises a camera, in particular a 3D camera. Optionally, the position sensor measuring device includes the same camera.

The measuring device is designed and set up to determine a piece size, in particular a piece height, based on a number of the area sections occupied by the at least one shipping item. The length of the shipping bag to be formed can be adjusted based on the piece size, in particular the piece length.

According to another embodiment of the fourth aspect of the invention, which can be combined with the previous one, the measuring device comprises a camera, in particular a 3D camera, which captures several image sections. The measuring device is designed and set up to determine a piece dimension, in particular a piece length, based on a preferably maximum distance of at least one image section occupied by the nature of a shipping item, in particular in relation to a predetermined reference plane. In particular, the reference plane corresponds to a sealing device for sealing at least one transverse strip of the formed web-shaped starting material. Alternatively or additionally, the reference plane corresponds to a separating device for separating a packaging bag from the starting material web along a transverse strip. According to an expedient embodiment, the measuring device can be designed and set up to determine the piece size, in particular the piece length, taking into account a predetermined distance between the at least one shipping item in the receiving cavity and the reference plane.

According to the fifth aspect of the invention, the system comprises at least one marking device for applying or attaching at least one visually visible marking on an outside of the packaging bag and / or the web-shaped starting material, in particular a wing, of the material web with a V- or U-shaped cross section. The marking device can be, for example, a printer, a label adhesive or the like.

In an embodiment of the fifth aspect of the invention, the marking device is arranged in the conveying direction in the area of the loading device, in particular the loading opening.

According to an embodiment of the fifth aspect of the invention, which can be combined with the others, the marking device comprises at least one driver movable transversely to the conveying direction for guiding a marking unit or a marking carrier, such as against the outside of the packaging bag and/or the web-shaped starting material.

Alternatively or additionally, the labeling can include information regarding the individual shipping item, such as a unit size of the shipping item, for example its unit weight, an item name and/or value of the shipping item.

According to a preferred embodiment of the system for converting a sheet-shaped starting material into one according to at least one of the aforementioned aspects of the invention, the feed opening extends in a plane that is oriented vertically or in a plane that is oriented horizontally.

A preferred embodiment of the system for converting a web-shaped starting material into packaging bags according to one or more of the above-described first to fifth aspects of the invention further comprises a feed device for withdrawing the web-shaped starting material from a material supply, such as a supply roll or a supply stack, in particular a fanfold stack . The feed device can, for example, comprise opposing conveyor rollers, conveyor rollers or the like. It may be preferred that the feed device has a drive unit, such as an electric motor, which drives at least one conveyor roller or roller. The feed device is preferably designed to pull the web-shaped starting material from a material web supply, for example a zigzag-folded supply stack, which can also be referred to as a fanfold stack, or from a supply roll.

In addition, the system may include a deflection, such as a deflection roller, for guiding the web-shaped starting material from the feed device along the deflection the forming device. In the conveying direction, the deflection is arranged between the intake device and the forming device. The deflection can expediently implement a means which, at least in sections, determines the conveying path of the web-shaped starting material between the feed device and the forming device. In particular, the forming device can be coordinated with the web-shaped starting material, the feed device and/or the forming device in such a way that the web-shaped starting material has a flat web-shaped extension on the forming device, in particular along an at least partial loop around the forming device. A flat web-shaped extension of the web-shaped starting material is to be understood in particular in relation to the extension of the starting material in the web width direction. In the conveying direction or the longitudinal direction of the web corresponding to the conveying direction, the flat web-shaped starting material can be guided along a curved course, in particular by deflection, the feed device and possibly a support roller or the like, the curved course being able to be C- or S-shaped in sections, for example. The deflection is preferably designed to change the course of the web-shaped starting material in the conveying direction, for example by at least 10° and/or not more than 180°.

Alternatively or additionally, the feed device can have at least one groove element for introducing at least one longitudinal cracks, in particular at least one longitudinal central groove, preferably two or three longitudinal central grooves, into the web-shaped starting material. Preferably, the at least one creasing element is matched to a folding means, in particular at least one, preferably first, folding roller. The system can expediently be equipped with at least one groove element, which is designed to introduce a groove or several grooves in the longitudinal direction of the web into the web-shaped starting material, preferably paper or cardboard, or consisting of it, in order to carry out the forming process of the web-shaped starting material along the longitudinal grooves to improve the folding materials. The at least one longitudinal groove is preferably introduced in accordance with DE io 2020 114211 Ai.

According to a further exemplary embodiment of the present invention, the system further has an alignment device which is arranged downstream of the conveying direction of the loading device in such a way that a packaging bag provided with a shipping item reaches the alignment device using gravity, in particular exclusively using gravity, and in addition is set up to align the packaging bag in a predetermined orientation. It has proven to be advantageous, particularly for downstream process steps in the processing of packaging bags, if they are present in predetermined, repeating orientations. According to an exemplary development, the alignment device is a passive device that itself does not carry out any active movement or active intervention or access to the packaging bag. For example, the system can be designed in such a way that the packed packaging bag leaves the loading device, in particular is released by it and/or falls out of it in the gravitational direction and reaches the alignment device, from which it is then brought into the predetermined orientation.

According to an exemplary development of the system according to the invention, the system further has a conveyor device, in particular a conveyor system, such as a continuous conveyor, in particular with a conveyor belt, for receiving a packaging bag provided with a shipping item and for further conveying the packaging bag. The conveyor device further contributes to automated packaging and shipping item handling. By means of the conveyor device, the packaging bags can be automatically brought from the packaging location to a handover or shipping location.

According to a further exemplary embodiment of the system according to the invention, the conveying device is arranged downstream of the aligning device in the conveying direction in such a way that a packaging bag provided with a shipping item and aligned by the aligning device reaches the conveying device using gravity. In other words, the packaging bag can initially leave the loading device unaligned in the direction of the alignment device and finally, after being aligned by the alignment device, arrive at the conveyor calibration direction and be conveyed further there in the predetermined orientation.

In a further exemplary embodiment of the present invention, the alignment device is set up and/or arranged in relation to the loading device in such a way that a leading end of the packaging bag can impinge on the alignment device and can be deflected in a predetermined direction. For example, the packaging bag falls out of the loading device under the influence of gravity and initially hits the alignment device with a leading end, which is arranged and / or set up to deflect the leading end in a specific direction so that the predetermined orientation can be adopted . For example, the deflection by means of the alignment device causes the packaging bag to tilt.

In a further exemplary development of the system according to the invention, the alignment device is designed as a deflection plate and/or as a slide aligned transversely to a direction of fall, which is in particular oriented exclusively in the direction of gravity, of the packaging bag from the loading device to the alignment device. The The deflection plate or the chute can therefore be oriented transversely to the vertical direction and, as soon as the leading end of the packaging bag has hit the deflection plate or the chute, it can be taken along or specifically deflected, so that a predetermined deflection takes place, which ultimately leads to the predetermined orientation of the packaging bag . After the initial deflection by the leading end hitting the deflection plate or the slide, the packaging bag can slide or slide down the slide or plate and finally reach the conveyor device.

According to a further exemplary development of the present invention, the alignment device is designed to align the packaging bag so that the marking is oriented vertically upwards. The marking is therefore always visible or readable for operators, scanners, automatic further processing devices or the like, so that automatic further processing of the packaging bag can take place.

To simplify readability, the following description of preferred embodiments of the various individually realizable or combinable aspects of the invention for the same or similar components are different Versions of systems for converting a web-shaped starting material into packaging bags use the same or similar reference numerals. The person skilled in the art understands that, although the embodiments of a system described below as examples sometimes embody several aspects of the invention combined with one another, the various aspects can each be implemented individually or in any combination with one another.

A system according to the invention for converting a web-shaped starting material, which defines a longitudinal direction of the web and extends between two longitudinal directions opposite in the web width direction, into packaging bags is generally provided with the reference numeral 100 or 200. The various versions of systems according to the invention, which are provided with the reference number 100 on the one hand or with the reference number 200 on the other hand, essentially only differ in the position of the various system components relative to one another and the resulting conveying path for the starting material.

The web-shaped starting material 1 is preferably made of cardboard or paper or consists of it. In addition to cardboard or paper, the starting material 1 can include an adhesive or the like for sealing the packaging bags 11 to be formed. An example of a packaging bag 11 that can be produced with the system according to the invention is shown in Figures 17-19.

As shown in Figure 1 or 2, the web-shaped starting material 1 for the system 100 (or 200) can be provided as a material web supply 2, for example in the form of a supply roll. The material web supply 2 is preferably arranged near the ground, so that even heavy, large material web supplies 2 can be used for lifting without cranes or similar aids. Instead, for example, a mobile support frame 20 can be used for a material web supply 2, as can be seen in FIG. The support frame 20 itself can be mechanically coupled to the system 100, for example plugged in, in order to set up an optimized alignment of the web-shaped starting material 1 relative to the feed device 110/210. The web-shaped starting material 1 rolled up to form the material web supply 2 has a web width direction B. The extension of the starting material 1 in the web width direction B corresponds to the cylinder height of the roll-shaped material web supply 2. The opposite, circular base surfaces of the roll-shaped or cylindrical material web supply 2 are through the opposite longitudinal edges 6 of the starting material web 1 formed. To form the roll-shaped material web supply 2, the starting material web 1 is wound in the direction of its longitudinal direction L. The system loo and possibly the support frame 20 stand on a surface, such as a hall floor, which extends essentially horizontally. A vertical direction V extends orthogonally on this surface in the sense of gravity.

To process the web-shaped starting material 1 into a plurality of packaging bags 11 through the system 100, the material web 1 is guided through the system 100 with a conveying direction F corresponding to its longitudinal direction L, and is pulled through it and thereby unwound from the roll-shaped material web supply 2. Within the various components of the system 100, the local conveying direction F along which the web-shaped material 1 is moved can be variable with respect to the vertical direction V as well as with respect to a horizontal direction.

The conveying path of the material web 1 through the system 100 according to the embodiments shown as examples in FIG. 1 or 2, as well as through the system 200 according to the embodiment shown as examples in FIGS ) from a material web supply 2 through a feed device 110/210, along a clamping device, such as a support roller 115/215, to a deflection, such as a deflection roller 120/220, and then to a forming device 130/230 and a subsequent loading device 150/250 and further to a conveyor device 170/270 and a sealing device 180/280 and finally a separating device 190/290.

In the embodiments shown here as examples, the web-shaped starting material 1 extends essentially flatly in the web width direction B from the material web supply 2 to the deflection roller 120/220, in particular in a horizontal direction. Starting from the deflection, the web-shaped starting material 1 is formed in the forming device 130/230 into a material web with a V- or U-shaped cross section and a receiving cavity 9 extending in the longitudinal direction L of the web. The receiving cavity 9 is delimited on the one hand by a pocket base 7 and on both sides thereof by wings 8 protruding transversely to the conveying direction F and/or the longitudinal direction L of the web and expands in the longitudinal direction L of the web. The material web 5 with a V- or U-shaped cross section is transferred from the forming device 130/230 to the feeding device 150/250. The loading device 150/250 has a loading opening 151/251 opposite the pocket base 7, through which shipping items 21 can be inserted into the receiving cavity 9. By means of the conveying device 170/270, the material web 5, which is covered with at least one shipping item 21 and is V- or U-shaped in cross section, is pulled further out of the feeding device 150/250 in the conveying direction F. A sealing device 180/280 introduces transverse strips 15 and longitudinal strips 16 into the V- or U-shaped material web 5 to form packaging bags 11 to shape. The separating device 190/290 separates packaging bags 11 occupied by at least one shipping item 21 from the material web 1. The sealing device 180/280 can be formed at least partially in functional union with the conveying device 170/270 and/or the separating device 190/290.

Figure 1 shows a side view of a first embodiment of the system 100 for converting the web-shaped starting material 1, which is in particular made of paper or cardboard, into packaging bags 11. A feed device 110 pulls the web-shaped starting material 1 from the material web supply 2. The feed device 110 is arranged in the vertical direction V above the material web supply 2. Downstream of the feed device 110, the web-shaped starting material 1, which may have been formed into a grooved material web 3 in the feed device 110 by means of a grooved element 105, is guided along a support roller 115. The support roller 115 can be referred to as a loose roller or dancer. The support roller 115 is mounted on the system 100, in the embodiment according to FIG. 1 on the feed device 110, so that it can move transversely to the conveying direction F. The support roller 115 is held movable relative to the retraction device 110 and/or a deflection 120 in order to carry out an evasive movement a. As shown in Figure 1, the evasive movement a can be aligned in the vertical direction V.

The support roller 115 can, for example, be biased downwards in the vertical direction V by a mass, in particular its own weight. Alternatively or additionally, the support roller 215 can be spring-loaded to carry out an evasive movement a. The support roller 215 is designed to be free of a pneumatic actuator. Contrary to the pretension of the support roller 215, the tensioning force of the web-shaped starting material 1 acts as a result of a tensile force acting on the starting material web 1 through a conveyor device 170 in the conveying direction F. With the help of the support roller, discontinuities between a conveying speed when pulling the web-shaped starting material web 1 from the material web supply 2 on the one hand and a conveying speed on the conveyor 170 and/or the separating device 190 on the other hand can be compensated for. By displacing the support roller 115 in the direction of the compensating movement a, the conveying path from the feed device 110 to the feed device 150 is extended, so that a buffer amount of web-shaped starting material 1 can be kept along the conveying path.

A deflection, which in the embodiment shown here as an example is implemented as a deflection roller 120, is arranged in the advance of the forming device 130. The web-shaped starting material 1 is supported along the deflection axis U on the deflection roller 120 before it is conveyed through the forming device 130. The deflection roller 120 or deflection roller extends in the direction of the deflection axis U over more than the initial width b of the starting material web i.

Figure 3 shows a deflection with a deflection roller 120 and an optional holding strap 125. The web-shaped starting material 1 is guided along a peripheral contact area 121. In the exemplary embodiment shown in FIG. 3, the circumferential contact area 121 extends over more than 90° around the outer circumference of the deflection roller 120 in accordance with FIG. The holding strap 125 can prevent the web-shaped starting material 1 from lifting off the deflection roller 120, which could otherwise lead to material jams or material tears.

3, the retaining strap 125 is guided along three belt deflection rollers or belt rollers 126, 127, of which, for example, a belt deflection roller 126 can be driven and a belt deflection roller 127 can be movably mounted to maintain belt tension. The driven belt roller 126 can provide a driving force for conveying the raw material web 1. Optionally, the belt roller 126 is provided with a freewheel, which is arranged in terms of drive technology between the drive motor and the retaining belt 125 itself. This makes it easier to restart the system 100/200 or when a new material web 5 is moved into the system 100/200. In the direction of the deflection axis U, the retaining strap 125 extends significantly shorter than the deflection roller 120.

The deflection realized here as a deflection roller 120 is arranged vertically above the forming device 130 in the vertical direction V. The deflection roller 120 is also arranged above the feed device 110, which is located above the material web supply 2. The deflection forms the top component of the system 100 in the embodiment according to Figure 1 or Figure 2. The arrangement of the deflection between the feed device 110 and the forming device 130 allows a compact design in the horizontal direction, so that the system 100 has a particularly narrow footprint in a logistics hall can be set up.

A forming device 130 is described in detail below with reference to Figures 4 and 5. Starting from the deflection, the starting material web 1 is conveyed downwards into and through the forming device 130 in the conveying direction F corresponding to the vertical direction V. The longitudinal edges 6 of the material web can essentially remain in the plane determined by the deflection, which extends from the deflection roller 120 to the conveyor 170. The central area of the material web in the web width direction B The forming device 130 is formed by folding means, which are realized here by folding rollers 131, 132 and 133, into a pocket base 7 of a material web 5 with a V- or U-shaped cross section, which is framed on both sides by wings 8, which extend up to the Longitudinal edges 6 extend.

The forming device 130 comprises a first folding roller 131, the roller axis W of which is aligned in space parallel to the deflection axis U and is arranged offset from the deflection axis U. In the conveying direction F, an axis distance X is provided between the roller axis W of the first conveyor roller 131 and the deflection axis U. An envelope distance Y extends transversely to the conveying direction F between the deflection axis U and the roller axis W of the first conveyor roller 131. A second folding roller 132 and optionally a third folding roller 133 arranged between the first folding roller 131 and the second folding roller 132 define the path of the pocket base 7 by the forming device 130. The roller axis W of the second folding roller 132 is arranged significantly further offset in relation to the deflection axis U in the direction of the conveying direction F by the forming device 130 than the axis distance X, preferably by 2 times to 5 times. Transverse to the conveying direction F (in the feeding direction E), the second folding roller 132 is further relative to the first folding roller 131 relative to the deflection axis U than the envelope distance Y, but not more than 100%, preferably 10% - 50%. The roller axes W of the folding rollers 131, 132 and possibly 133 are spatially parallel to one another.

In an expedient embodiment, the conveyor rollers 131, 132 and 133 are formed by a pair of roller disks 135, between which a spacer 134 is arranged. The distance between the roller disks 135 relative to one another in the direction of the roller axis W, defined by the spacer 134, can correspond to the distance between the groove disks 107, 207 of a groove element 105 upstream of the forming device. Alternatively, rolling disks 135 and spacers 134 can be designed as a one-piece molded part. However, it is essential that all of the aforementioned designs of the spacers 134 have a smaller outer diameter than the rolling disks 135. Alternatively, the conveyor rollers 131, 132 and 133 can be cylindrical.

The forming device 130 has a guide surface 140, which is realized in sections by counter-bearing rollers 142, 143 assigned to the conveyor rollers 131, 132, 133. The V- or U-shaped material web 5, in particular the pocket base 7, can be guided along the guide surface 140. Preferably, the guide surface 140 extends parallel to the plane spanned by the deflection and the conveyor device 170. When executing the system 100 according to Figures 1 or 2, the guide surface 140 extends in a substantially vertical plane. Figures 6 and 7 show various views of another embodiment of a system 200 for forming a web-shaped starting material into packaging bags. In this system 200, too, the deflection roller 220 is arranged in the vertical direction V in the uppermost area of the system 200. In contrast to the systems 100 described above, however, the conveying direction F in the forming device 230 as well as at the exit of the feed device 210 is aligned essentially horizontally. The retraction device 210 is described in detail below with reference to FIG. 8.

For the arrangement of the guide surface 240 and its arrangement in relation to the folding rollers 231, 232 and 233 as well as the deflection roller 220, what was previously explained with reference to FIGS. 4 and 5 essentially applies. The guide surface 240 extends through both the deflection device 230 and the loading device 250. Several sections of the guide surface 240 and counter bearing rollers 241, 242, 243 and 245 arranged therein form a section area for the outside of the material web 5 in the area of the pocket base 7.

Inside the forming device 230, a pair of opposing guide rods 236 are provided, the transverse distance of which tapers in the conveying direction F. The guide rods 236 are arranged on both sides of the folding rollers 231, 232 and 233 transversely to the conveying direction F. In the conveying direction F, the guide rods 236 extend essentially from the deflection roller 220 to the loading device 250. The outer sides of the wings 8 can be guided along the guide rods 236 to form the V- or U-shaped material web 5. The counter bearing rollers 241, 242 and 243 are arranged in the area of the forming device 230 and can each be assigned to a folding roller 231, 232 and 233. The counter bearing rollers 245 are arranged in the area of the loading device 250 opposite the loading opening 251. The guide surface 240 extends essentially in a horizontal plane in the embodiment of the system 200 shown in FIGS. 6 and 7.

The feeding device 250 is arranged downstream of the forming device 230. The loading device 250 has a loading opening 251 which is completely surrounded by a solid frame 255. The interior 259 of the loading device 250 extends in the loading direction E behind the frame 255. In the conveying direction F, the loading opening 251 has a clear length f, which is the maximum length of insertable shipping items certainly. The loading direction E, through which shipping items (not shown) can be inserted through the loading opening 251 of the loading device, extends perpendicular to the conveying direction F and the plane defined by the guide surface 240.

A conveyor device 270 is arranged downstream of the loading device 250, which can grip the longitudinal edges 6 of the material web 5 and convey it in the conveying direction F. Following the conveyance 270, a sealing and separating device 280/290 is provided for forming and separating packaging bags 11 from the web-shaped starting material 1.

Figure 8 shows a side view of a feed device 210. The feed device 210 differs from the feed device 110 essentially only in the orientation of its conveying direction F at the entrance or exit of the feed device. The feed device 210 comprises a pair of conveyor rollers 211 and 212, between which the web-shaped starting material (not shown in detail in Figure 8) can be conveyed. The lower conveyor roller 211 is provided with a drive device which drives the conveyor roller 211. The upper conveyor roller 212 rolls on the web-shaped starting material and follows the movement of the lower conveyor roller 211 in the opposite direction of rotation. In the absence of starting material, the conveyor roller would roll on the lower conveyor roller 211.

The feed device 210 comprises a creasing element 205. In the preferred embodiment shown here, the creasing element 205 is arranged upstream of the pair of conveyor rollers 211, 212. The scoring element 205 comprises two axially offset scoring disks 207, 208. The scoring disks 207, 208 are spring-loaded on a pivotable arm 216 by a compression spring 209. It is conceivable that the grooved disks 207, 208 are kept rotationally rigid. The grooved disks 207, 208 are preferably rotatably mounted. The grooved disks 207, 208 roll on the counter bearing roller 206. The compression spring 209 pushes the grooved discs against the counter-bearing roller or counter-bearing roller 206. The web-shaped starting material (not shown in more detail in FIG. 8) is conveyed by the feed device 210 along the creasing element 205, which longitudinally grooves the web-shaped starting material 1 in order to turn it into a grooved web material 3 to shape. Downstream of the feed device 210 in the forming device 230, the folding means cause the web-shaped material 1 to be folded over, preferably along the longitudinal grooves introduced by the groove element 205, in order to design the material web 5 with a V- or U-shaped cross section. The rolling disks 135 mentioned at the beginning are designed as relatively narrow disks, with each of the disks running along the respective longitudinal groove. It has been found that the forming of the web-shaped starting material 1 is simplified if the rolling disk runs along the longitudinal axis. Advantageously, the rolling disk 135 has a rounding or a truncated cone or a double truncated cone on the outer diameter.

Figures 9 and 10 show a loading device 150. With the exception of the orientation of the guide surface 140, the loading device 150 of the system 100 essentially corresponds to the loading device 250 of the system 200. The counter bearing rollers 145 are in the area of the loading device 150 in the loading direction E opposite the loading opening 151 - '2^ - arranged. The counter bearing rollers 145 limit the depth in the loading direction E up to which a shipping item (not shown) can be used. The feeding direction E is oriented in the horizontal direction in the system 100 shown in FIGS. 9 and 10.

In the conveying direction F, the loading opening 151 has a clear length f. Transverse to the conveying direction F, the loading opening 151 has a clear width q. The clear length f and the clear width q of the loading opening 151 are defined by a frame 155 which completely surrounds the loading opening 151. The loading opening 151 is delimited transversely to the conveying direction F by opposing guide plates 156. The guide plate 156 has a rounded bend 157 in the area of the loading opening 151, so that a shipping item can easily slide along the guide plate 156 into the loading opening 151 and a receiving cavity 9 provided behind it for a V- or U-shaped material web 5 (see FIG. 1). . The guide plates 156 implement guide plates 144 behind the frame 155 in the interior 159 of the loading device 150 for guiding the wings 8 in the conveying direction F on their insides defining the receiving cavity 9. Further guide plates 146 can be provided on their outer sides to guide the wings 8 in the conveying direction F.

Figure 11 shows a sectional view of the loading device 150 through a sectional plane behind the frame 155. The wings 8 of the V- or U-shaped material web 5 in the area of the loading device 150 are shown in dashed lines in Figure 11. The guidance of the right wing 8 on the one hand and the left wing 8 on the other hand between the respective guide plates 144 and 146 is clearly visible in the sectional plane. The guide plates 144, 146 form a funnel-like insertion section 153, which serves to safely feed the V- or U-shaped material web 5 from the forming device into the loading device 150.

Downstream of the feed opening, the outer guide plates 146 form a funnel-like transfer section 154 for feeding the longitudinal edges 6 of the material web 5 into the contact area of two mutually rotating conveyor rollers 171, 172. The conveyor rollers 171, 172 implement a conveyor device 170, which pulls the material web 5 through the forming device 130 . Preferably, the conveyor rollers 171, 172 have cooperating cylindrical outer peripheral surfaces. The conveyor rollers 171, 172 can apply high tensile stresses to the material web 5 in order to realize the transformation from a flat starting material web into a formed material web along a particularly short folding path by the forming device 130. Figure 12 shows an optional embodiment of a pair of conveyor rollers 171, 172, which forms a sealing device 180. A first conveyor roller 171 has a full-circumference annular projection 173, which rolls in a corresponding full-circumference annular groove 174 of the second conveyor roller 172. The sealing device 180 formed by the pair of conveyor rollers provides the material web 5 to form a Packaging bag n with a longitudinal strip 16. Optionally, a cold seal adhesive can be applied to the material web 5 on the inside of the receiving cavity 9, at least in the area of the longitudinal strips 16 and the transverse strips 15. In an alternative embodiment of the conveyor rollers 171, 172, at least one conveyor roller 171, 172 is cylindrical on the outside.

Figure 13 shows schematically the sealing and separating device 180/190. The V- or U-shaped material web 5 is conveyed in the conveying direction F by the conveying device 170 to and through the separating and sealing device 180/190. The sealing device 180 comprises a pair of jaws located opposite one another transversely to the conveying direction F, which can be pressed against one another to form a transverse strip 15 that seals a packaging bag 11. The separating device 190 comprises at least one, in particular scissor- or guillotine-like, cutting edge and/or a plurality of cutting-like teeth for separating a packaging bag 11 from the web-shaped starting material 1. At least one jaw of the sealing device 180 can be designed with a cutting edge of the separating device 190, so that during a pressing process of the jaws against each other at the same time as the packaging bag 11 is sealed along a transverse strip 15, the packaging bag 11 is separated from the material web 5.

Figure 14 shows a schematic representation of a loading device 150 with a measuring device with an optical sensor in the form of a camera 158. Figure 15 shows a perspective view of a loading device 150 with a camera 158, which can serve as an optical sensor of a position sensor and / or a measuring device. The camera 158 should be understood as an exemplary sensor within the scope of the present disclosure.

The camera 158 is carried on the frame of the loading device 150. In order to exclude a collision between shipping items 21 and the camera 158, the camera 158 is arranged upstream of the loading opening 151. The camera 158 is essentially aligned with the feed opening 151 in accordance with the conveying direction F. The viewing direction of the camera 158 is aligned such that it looks into the receiving cavity 9 of a material web extending in the area of the loading device 150.

It may be preferred that the camera 158 captures an image area which includes a reference area along an inner edge of the loading opening 151, in particular along the guide plate 144, the guide plate 156 and/or the bend 157. If the camera 158 forms part of a position sensor, the system 100 detects any coverage of the reference area by an object, such as a body part of a user and/or a Shipping items are recorded to accordingly prevent movement of one or more components of the system 100.

In the schematic representation according to FIG. 14, the camera 158 captures a reference plane defined by the sealing device 180. The predetermined distance c between the separating and sealing device 180/190 and the shipping item 21, which prevails as a result of deformations of the material web 5, can be previously known or can be determined using the measuring device. The distance c can, for example, correspond to a known taper of the material web in the transfer area 154. The camera 158 is also used to record the distance from a rear edge of the shipping item 21 in the conveying direction F to the reference plane. The measuring device can thus determine the piece length SL of the shipping item. The measuring device can also determine other piece dimensions, such as the piece width SB transverse to the conveying direction F and the piece height SH in the feeding direction E.

At the beginning of a measuring cycle, a computer, for example a PLC, computing unit or similar central machine control unit, can be used to transmit a signal to the sensor intended for length measurement (here: the camera 158). The sensor then detects the shipping item 21. For example, the camera 158 can record an image and divide the image into a large number of image sections, for example a field matrix comprising 5x8 fields. The possibly different distances of each of these image sections from the reference plane are determined and transmitted back to the computer. The computer then determines the maximum value of the different distances. The distance c between the shipping item 21 and the front end of the shipping bag 11 to be formed as well as a second distance d, possibly corresponding to the distance c, in the wake of the shipping item 21 can be predetermined for the computer. The computer can then determine a feed rate along which the conveying device 170 conveys the material web from the loading device 150 through the sealing and/or separating device 180 and/or 190, and which determines the overall dimension 9 of the packaging bag 11 to be formed in the longitudinal direction L of the web. The overall dimension 9 can optionally be compared by the computer with at least one minimum and/or maximum threshold value in order, for example, to identify shipping items 21 with an impermissible length.

Alternatively, a piece size, such as a piece height SH of a shipping item 21, in particular a particularly narrow shipping item 21, can be determined by a preferably optical sensor of the measuring device based on the reflection behavior on an inside (or outside) of the material web 5 in the area of the loading opening 151. Figure 16 shows a perspective view of the loading device 150. A light grid 149 of a safety sensor extends along the loading opening 151, which is designed to detect when a user places a body part, in particular a hand or an arm, into or through the loading opening 151 Loading opening 151 has been inserted into the interior 159 of the loading device 150. The light grid 149 essentially covers the entire area within the frame 155 spanned by the loading opening 151. If the light curtain 149 detects a collision with a user or an object, the safety sensor causes at least one or more components of the system 100 to be deactivated in order to exclude any risk to the user.

The system 100 also includes a marking device 160, which is arranged here as an example inside 159 of the loading device 150. The marking device 160 includes a driver 161 in order to press labels, for example shipping items, against an outside of the material web 5 in the area of the loading device 150. The system 100 may include a scanner or the like to identify the shipping items 21 fed into the loading device 150 and cause the identification device 160 to provide a corresponding label for the packaging bag 11 of the identified shipping item 21.

Figure 17 shows a side view of a shipping bag or packaging bag 11. The packaging bag 11 is sealed by transverse strips 15 and opposite the bag base 7 by a longitudinal strip 16. Inside the packaging bag 11 there is a shipping item 21 shown in dashed lines. The shipping item 21 has a piece length SL and a piece height SH. The length 9 of the packaging bag 11 corresponds to the sum of the piece length SL, the predetermined distance c and the second distance d. Figures 18 and 19 show other views of the packaging bag 11 shown in Figure 17.

2oa-2od show schematic principle sketches of a further exemplary embodiment of a system 100 according to the invention, in which the transfer of a completed packaging bag to a conveyor 320 arranged downstream of the loading device 150 is shown by means of an alignment device 310 arranged between the loading device 150 and the conveyor 320.

In Figure 20a, the packaging bag 11 is still arranged in the loading device 150 and has a leading end 12 pointing downwards in the gravitational direction, a trailing end 14 in the opposite direction and has a through on an outer surface a marking device 160, 260 applied marking, which can be referred to as a marking page and is provided with the reference number 13.

In the sequence according to Figures 2ob-2od, the transfer process of the packaging bag 11 onto the conveyor device 320 designed as an endless conveyor belt is shown. In the exemplary embodiment, the alignment device 310, designed as a deflection plate or slide, is arranged in the vertical direction below the output opening of the loading device 150, so that the packaging bag 11 (FIG. 20b) falling out or falling down is initially also inclined with respect to the leading end 12 the vertically oriented deflection plate or slide 310 occurs (Figure 20c) and is brought into a specific orientation by this. This is done by the leading end 12 following the course of the alignment device 310 and thus being tilted before the packaging bag 11 is transferred to the conveyor belt 320 in the predetermined, desired orientation with the marking side 13 facing upwards in the vertical direction.

The features disclosed in the above description, the figures and the claims can be important both individually and in any combination for the implementation of the invention in the various embodiments.
