Abstract

The strapping arrangement has multiple cylindrical piece goods, particularly cylindrical drums (2,3,4,5), arranged on a pallet (6), where the cylindrical drums are arranged with one of its front sides in a vertical manner and are combined together with the pallet to a transport unit (1). The strapping (15,16,17,18) is guided over a front-sided upper surface of one of the piece goods. The upper surface of one of the piece goods is present against the lower side of the pallet. Independent claims are included for the following: (1) a method for producing a strapping arrangement for multiple cylindrical piece goods, particularly cylindrical drums; and (2) a strapping system with a receiving unit.

Description

The invention relates to a Umreifungsanordnung for a pallet with a plurality of arranged on the pallet cylindrical piece goods, in particular cylindrical barrels or barrel-like cargo, which are arranged standing with one of its two end faces and combined with the pallet to form a transport unit, wherein the transport unit with at least a first , At least approximately horizontally and on the circumference of the transport unit extending annular strapping is included, and second strapping, with which the cargo secured to the pallet, in particular attached to her, are.

Larger piece goods whose outer shape either no or insufficient surfaces for a form-fitting arrangement of cargo side by side on a pallet, for example, the widely used so-called europallets allow, can be secured relative to each other on a pallet only with considerable effort. The problem here is mainly non-straight edges or areas of cargo, where even strapping can not be clearly positioned. This applies in particular if these are upper edges of the piece goods and these goods are located on the sides of the transport unit.

Although such piece goods, such as at least substantially cylindrical barrels, kegs or tubes, with one of their end faces in each case arranged side by side on the pallet and then tied together with one or more horizontal strapping. As a strapping material here both plastic bands and plastic stretch films are used. However, there is a risk that the strapping will slip during a tilting movement of one of the piece goods and thereby changes the position of the piece goods in the transport unit, which may eventually lead to dangerous for the transport positional shift. In particular, the oscillations occurring in a transport by truck often produce positional shifts of the cargo on the pallet, despite such strapping usual. Since at most only punctiform or linear touching, arranged on a pallet, piece goods usually Even then are able to move at least slightly relative to each other, even in spite of a horizontal Bandumreifung a positional shift may be possible.

For an improved securing of the piece goods so far cost and time-consuming measures must be taken, for example, cover the top of a barrel position with cardboard, angled plastic profiles or the like to lead to a strapping on the cardboard, along a diameter line on the barrels and around the pallet can. It is hereby aimed to bring the strapping on the top of the transport unit as far as possible in abutment against these aids, the arranged between the cargo and strapping aids should prevent slippage of the respective strapping. But even so that a sufficient security of the cargo is hardly possible, among other things, because the positions of the strapping on the cardboard are not clearly specified. The resulting shifts in strapping can lead to dangerous loosening of the transport unit.

To achieve an improvement here, was in the DE 10 2007 032 860 A1 already proposed to apply over the top of the transport unit to run between the cargo strapping, which rest on an upper horizontal strapping on opposite sides. These designated as vertical strapping second strapping run on both sides of the pallet in each case substantially in the vertical direction down to the range. This vertical second strapping then runs along the underside of the pallet, is here against the pallet and generated on the horizontal strapping due to their belt tension a compressive force by which the cargo is held on the pallet or connected to this. This strapping arrangement of DE 10 2007 032 860 A1 has proven itself in practice. If anything, it can be considered less optimal in this strapping arrangement that the compressive force with which the piece goods are held on the pallet, both on the size of the belt tension of the horizontal, and the belt tension of the vertical strapping is dependent. In addition, the Umreifungsanordnung is the DE 10 2007 032 860 A1 especially, but not exclusively, for kegs with a horizontal Collar on the lateral surface, with the possible slippage of the horizontal strapping is prevented.

The invention is therefore an object of the invention to provide a way to improve the security of particular more, cylindrical and relatively large, piece goods, especially of barrels or barrel-like piece goods, on a pallet, due to their outer shape and mass in one movement or acceleration of the pallet even then show the tendency to perform relative movements to each other when stretched around a horizontal band strapping.

The object is achieved according to the invention in a Umreifungsanordnung of the type mentioned by the characterizing part of claim 1. In the solution according to the invention, therefore, at least one strapping of a second type may be provided, which has a course deviating from the course of the at least one strapping of the first type and, in particular, not in an orientation which is at least substantially horizontal over its entire circumference, around several or around all cylindrical surfaces Piece goods of the transport unit is guided around. The at least one existing strapping of the second type should instead extend obliquely from the pallet on both sides of at least one or more piece goods and be guided over the upper end face of the at least one cylindrical piece goods. With its lower portion, the at least a second strapping should rest against the underside of the pallet. If the underside of the pallet and at least one upper end side of a piece goods is aligned horizontally, the sections of the at least one second strapping which bear against these surfaces can also have a substantially horizontal orientation. Nonetheless, lateral portions of the at least one second strap should have a different orientation than horizontal straightening. The object is also achieved by a method according to claim 9 and by a strapping system according to claim 16.

The inventive concept for securing cargo of cylindrical cargo on pallets differs fundamentally from that of the previously known DE 10 2007 032 860 A1 , In contrast to DE 10 2007 032 860 A1 the at least one runs second strapping over the upper face of one or more cylindrical piece goods. This strapping of the second type should bear against this end face at least at raised points of the upper end face, such as a frontal outer raised bead of a barrel. In this context may be understood by a concern against the front side direct contact of the strapping with the top of the piece goods or only an indirect contact with the top via an intermediate element. Such an intermediate element could, in particular, be a foil wrapped around the drum. Dimensionally stable aids, such as cardboard, which are used in the prior art for the indirect application of strapping on the piece goods to have a contact element with a diverging advantageous general geometric shape available, are not required in connection with the present invention or result in use no significant additional benefits. In embodiments which are still part of the invention, however, such dimensionally stable auxiliary means can additionally be provided. It is in principle preferred in connection with the present invention that for securing the piece goods on the pallet only (in the sense of exclusively) strapping are provided, in particular only strapping of the first and the second type.

Although it is preferred that a second strapping here rests against only one and not against several of the cargo. In principle, however, it can also be provided that the strapping abuts against the upper side of a plurality of cylindrical piece goods arranged next to one another. From the one or more upper sides of the at least one piece goods, the second strapping then extends obliquely downward in the direction of the pallet due to deflections of the strapping on the edge of the front upper side of the at least one piece goods. Here, the self-contained strapping provided with a band tension encompasses the pallet and rests against its underside. With respect to a projection of the upper end side of the at least one piece goods on the top of the pallet, the strapping is advantageous at the top of the respective piece goods and at the bottom of the pallet on different sides with respect to a diameter line of the top of the piece goods. Due to the band tension in the second strapping as well as the maximum low nondestructive extensibility of the Umreifungsbands the strapping, this arrangement prevents that the strapping either on the upper end side of the piece goods on the widest point of the upper end face can get or slip on the underside of the pallet and thus could solve the securing or connection of the piece goods to the pallet. Due to their course on the piece goods and on the pallet, the respective second strapping presses the piece goods with a force acting on the pallet in addition to the weight force of the piece goods.

In a particularly preferred embodiment according to the invention, a second strapping is assigned to only one of the piece goods arranged on the pallet. In this embodiment, the respective second strapping extends only over the top of its associated one piece goods and is then deflected on both sides of its associated piece goods obliquely downwards in the direction of the pallet. Preferably, for each cylindrical piece goods such only the respective piece goods assigned second strapping is provided, with which the piece goods is immovably bound to the pallet. In deviating possibly inventive embodiments, it is also possible in principle that not all arranged on a pallet piece goods are secured with a second strapping, or this is associated with such a second strapping. It is conceivable to provide only some of the piece goods, preferably in the form of barrels, with one or more second strappings which have laterally sloping band sections on the piece goods. The securing of only at least one but not all piece goods can already lead to an improvement in transport safety, since the not provided with a second strapping cargo by the horizontal first strapping to the provided with a second strapping cargo are positively pressed and thereby already a respect the stability improved arrangement of all cargo of each pallet can be achieved.

The at least substantially horizontally aligned, at least a first strapping, should preferably surround all on the pallet cargo on the outside of the pallet and the cargo arranged thereon having transport unit and preferably be mounted prior to attachment of the inclined second strapping. The following attached one or more second strapping are thus on at least a first strapping on. The at least one contact point between the respective first and second strapping is preferably located in a section of the second strapping in which the latter runs obliquely downwards from the upper end side of the piece goods towards the pallet. This leads to an additional securing of the position of the second strapping, as this, on the one hand, deflects the second strapping in the area of contact with the first strapping and, as a result, undergoes an additional safeguard against slipping. Likewise, the first strapping in the contact area also experiences a deflection and thus an increase in the belt tension. In connection with the present invention, the at least one horizontal strapping furthermore exerts a second function, since it abuts against the latter at the outer edge of the pallet edge at the transport unit and thus additionally secures its position on the pallet. Advantageously, the piece goods are arranged on the pallet in such a way that adjacent piece goods touch each other.

The present invention is particularly suitable for conventional cylindrical barrels, in particular for those which have a straight cylindrical shape, in this case also for such barrels, which are provided with a flat lateral surface without raised points against which the horizontal strapping could be positioned. Such or a cambered shape of the cylindrical piece goods is in the Umreifungsanordnung the DE 10 2007 032 860 A1 advantageous, so that the upper horizontal strapping, are not moved by the resting on her vertical strapping down. In the present invention acts on the horizontal first strapping substantially no, but at most a comparatively small, such directed downward in the direction of the pallet, whereby the possibility of slippage of the horizontal strapping is at least considerably minimized.

The object is also achieved by the method according to claim 9, which describes a method with which a strapping arrangement can be achieved, as indicated in claim 1. The advantages discussed in connection with claim 1 and in the claims dependent thereon have also for the inventive Procedure validity. With this method, strapping arrangements of preferably palletized barrels or barrel-like piece goods are produced with at least one first substantially horizontally oriented and with at least one second strapping, in which the second strapping over the upper end face of the cargo, there in particular off-center, are guided and from there extend on either side of one or more piece goods with obliquely extending portions of the strap to the palette to encompass the pallet.

In a preferred embodiment of the method according to the invention, only one piece of goods is strapped in each case with one of the at least one second strapping and is thus assigned a piece good. Such a connection of individual preferably designed as barrels or barrel-like piece goods by means of a strapping associated only with this barrel is a departure from the decades-long practice that strapping always have to surround the entire transport unit. It has been found within the scope of the invention that, despite the cylindrical shape of barrels, it is possible to apply a strapping to a barrel so that it does not slip and to secure the barrel to the pallet by gripping the pallet with the same strapping.

In a preferred embodiment of the method according to the invention, the at least one horizontal strapping and then the one or more second strappings with slanted strip sections should first be applied. In this case, it is likewise preferred if the second strapping over which the at least one horizontal first strapping is guided, so that the respective second strapping rests against an outer side of the first strapping and presses against this.

An advantageous as automated as possible attachment of second strapping can be achieved so that a position of the pallet is changed with respect to a strapping for attaching a plurality of second strapping, during the attachment of the plurality of second strapping. For this purpose, the pallet can in particular be rotated about a vertical axis of rotation so that it is arranged in different rotational positions relative to a strapping system can be. In each of these rotational positions, one of the second strapping can be attached to different piece goods. It is preferred that by means of a conveyor system, the pallet of the strapping system is fed in a position in which without the execution of a rotation of the pallet, the first of the second strapping can be attached.

The problem is finally solved by a strapping according to claim 16. In contrast to previously known strapping systems in which the strapping means are always arranged completely in a vertically oriented plane for strapping deviating from horizontal strapping, the strapping system according to the invention provides inclined lateral sections of the strap guiding means which are located between the upper and lower portions of the strap guiding means are arranged and the latter connects to each other. Since an upper and a lower portion of the tape guide means are arranged parallel to each other but possible offset from each other as possible, the inventive tape guide means are in an inclined plane, ie a plane provided with an inclination. Hereby, second strapping according to the invention can be produced with obliquely extending strip sections, with the use of which, in particular, barrels or other barrel-like piece goods can be connected particularly advantageously to the pallet to form a transport unit.

The course or inclination angle of the slope of the lateral portions of the tape guide means results at least approximately from the distance that have opposite ends of each of the upper to the lower portion of the tape guide means. Although the two inclined tape guide means preferably also run at least substantially parallel to each other, but they can in principle also be aligned non-parallel to each other. With such a strapping system strapping according to the invention can be generated due to the lateral inclined portions of the tape guiding means, which have two lateral obliquely inclined band sections instead of vertical band sections.

In a preferred embodiment of the invention, the strapping system is provided with a turntable on which the respective pallet is arranged with their cargo for attaching at least the second strapping. The turntable is provided with means for generating rotational movements of the turntable about a vertical axis of rotation, whereby the turntable can be arranged with the pallet arranged thereon in different rotational positions. This makes it possible to arrange the pallet and the piece goods in predetermined relative positions with respect to the tape guide means. This in turn makes it possible in an automated manner to attach a second strapping with obliquely extending lateral band sections to each piece goods.

In a further preferred embodiment, the strapping system has a lower portion of the tape guide means, which is provided with at least one movable lance. By the mobility of the at least one lance can be ensured that the tape guide means can be arranged in the preferred form of at least one movable lance below the bearing surface of the pallet, but above a footprint of the pallet. Although the tape guide means can be arranged self-contained, they reach through the lance arranged on the turntable pallet in the footer. The at least one lance should for this purpose be transferred from an open position in which the lance the area of the turntable so that a pallet can be placed on the turntable in a closed position. When transferring from the open position to the closed position, the pallet with its piece goods should expediently already be arranged on the turntable in the position in which a first of the several second strappings is applied. The at least one lance is in this case retracted from the open position from below the bearing surface having position of the pallet in the recessed foot area of the pallet and in this case closed the tape guide means in itself. In this way can be subsequently moved by the tape guide means a strapping that is closed in itself and rests against the at least one piece goods and against the pallet.

In a preferred embodiment of the invention, the lower portion of the tape guide means may also be provided with two movable lances, at least in sections, preferably completely, the lower portion of the tape guide means result. The two lances are advantageous both for the transfer of their open position in the closed position, as well as from the Locking position in the open position in opposite directions. The two lances have in this case a longitudinal extent in the direction of the intended band movement, wherein the longitudinal extent of the two lances are aligned. The directions of movement of the two lances preferably extend parallel to their longitudinal extent. In the open position of the lances, the two mutually facing ends of the lances are arranged at a distance from each other, which allows to arrange at least a part of a pallet between the ends. In the closed position, the two mutually facing ends of the two lances are arranged with little or no distance from each other.

Further preferred embodiments of the invention will become apparent from the claims, the description and the drawings.

In Fig. 1 a transport unit 1 according to the invention is shown, in which four cylindrical drums 2, 3, 4, 5 are arranged on a square pallet 6. The barrels are standardized so-called bung casks. The pallet 6 is a standardized pallet, as used for example in the chemical industry. The exemplary embodiment is a standardized wooden pallet designated as CP9 with a bearing surface 7 of 1140 mm × 1140 mm. In other embodiments of the invention, of course, other pallets and cargo may be provided, the invention is basically suitable for each type of pallet, regardless of their size. The storage area 7 of the pallet 6 for the here provided as barrels 2-5 piece goods is formed by a layer 8 wooden boards, which is arranged parallel to and at a distance to a substrate on which the pallet 6 stands. At the bottom of the layer 8, a central and two outer pallet feet 9a, 9b, 9c are fixed, through which the layer 8 can be arranged at a distance from the respective substrate. The pallet feet 9a-c are each formed from a plurality of vertical struts and a longitudinal strut, whereby the pallet feet 9 have openings 10 between the vertical struts. In addition, openings 11 result due to the distances with which the pallet feet 9a-c are arranged relative to one another. Of course, in connection with the invention, other piece goods than the barrels 2-5 shown and other pallets than the pallet 6 provided in the embodiment can be used.

The barrels 2-5 are in two rows, each with two barrels per row, so that the barrels do not protrude beyond the bearing surface 7. The barrels 2-5 are in each case with their lower end face on the pallet 6, so that the respective longitudinal axis of the substantially straight-cylindrical wall of the barrels 2-5 runs parallel to a vertical, provided that the pallet 6 is arranged on a horizontally aligned bottom surface. At the top, the drums 2-5 each terminate with a lid which forms a substantially circular end face 2a, 3a, 4a, 5a of the drums 2-5. The end face 2a-5a may in this case be surrounded by a raised bead 2b-5b. The end face 2a-5a and the bead 2b-5b represent an upper side of the barrels. In the region of the respective end face 2a-5a of the barrels 2-5, these can each have one not shown have closable filling and removal opening through which the barrels filled with liquids and the latter can be removed. Each adjacent barrels 2-5 are with their lateral surfaces against each other. Thus, each barrel is 2-5 against two adjacent other barrels. In the embodiment of Fig. 1 the barrels 2-5 on their lateral surfaces in each case two spaced apart horizontally around the lateral surface extending collars 2c-5c. The adjacent barrels are thus each with their frets 2c-5c against each other.

The transport unit, comprising the pallet 6 and the piece goods located thereon, in the exemplary embodiment, four barrels 2-5 have, as self-contained first strapping on one over its entire length horizontally aligned and provided with a belt tension strapping 14. By means of a plastic band - and a running on the band friction welding for connecting two overlapping tape ends - produced and provided with a belt tension horizontal strapping 14 surrounds the circumference of the transport unit horizontally and is here above the upper collars 2c-5c against all barrels on which the horizontally tensioned strapping band is deflected. All barrels on the pallet are within the horizontal strapping which presses barrels 2-5 against each other in the manner previously described.

As in Fig. 1 can also be seen, each barrel is provided with a second self-contained strapping 15-18. In the exemplary embodiment, each of the second strapping 15-18 is designed with the same type of band, with which the first strapping is carried out, for example, with PET straps with the masses 16 x 1.0 mm. In other embodiments, of course, other strapping bands can be provided, to which a sufficient for securing the piece goods tape tension applied and which can be processed by strapping devices. Commercially available polyester or polypropylene tapes are particularly suitable for this purpose. Of course, different types of belts, in particular with regard to the materials used and the dimensions, can also be provided for the first strapping type and the second strapping type.

In each of the barrels 2-5, the second strapping having a length of an at least substantially rectilinear upper band portion 15a-18a is passed over the upper end surface of the respective barrel 2-5, which is smaller than the diameter of the circular upper end surfaces 2a-5a the barrels. The upper band portion 15a-18a is in this case each non-parallel to the two each at a corner 6c of the pallet 6 abutting side edges 6a, 6b of the pallet aligned in their area with each one of the second strapping 15-18 to be mounted barrel the pallet 6 is arranged. Each barrel is located in the area of one of the corners of the pallet. Preferably, a projection of the upper band portion 15a-18a on the pallet 6 together with the two aforementioned side edges 6a, 6b of the pallet 6 each include an angle α of at least approximately 45 °.

At the points of the edge of the end face 2a-5a of the upper end face of the respective barrel 6, at which the band of the second strapping 15-18 leaves the upper end face 2a-5a, the band is deflected in the direction of the pallet 6. The tape runs here on both sides of the barrel 2-5 each with a band section 15b-18b; 15c-18c from the upper end face of the barrel 2-5 to a side edge 6a, 6b of the pallet 6 with an oblique orientation. In the context of the invention, "oblique" is understood to mean an orientation that deviates from an (imaginary) vertical that intersects the respective lateral band section 15b-18b, 15c-18c and an angle β with a horizontal, preferably 50 ° <β <80 °, more preferably 60 ° <β <75 °. In the exemplary embodiment, the angle β is preferably about 70 °. Each of the lateral and oblique band portions 15b-18b, 15c-18c of the second straps 15-18 abuts against one of the four side edges 6a, 6b of the pallet 6, respectively, where the band is deflected under the pallet. The second strapping 15-18 is thus annularly closed in itself. The upper band portion 15a-18a of the respective second strapping is also pressed in a form-fitting manner against the circumference of the upper end side of the respective piece goods due to the course of the band and the applied band tension. Due to the larger compared to the upper band portion 15a-18a diameter of the cargo, the strapping can not slip off the cargo and also pushes the cargo against the pallet.

In the Fig. 2 . 3 . 4 In various views, a strapping system 25 is shown, with the inventive strapping arrangements and transport units 1 can be generated. Apart from the differences described here, the strapping system corresponds to conventional vertical strapping systems with which vertical strapping can be carried out, ie strapping in which the strapping band is vertically aligned in sections.

In the Fig. 2 shown inventive strapping 25 has a conveyor 26, with the pallets 6 and disposed thereon barrels 2-5 a Umreifungsportal 27 of the strapping 25 and can be led away from this. For this purpose, the conveying system 26 has as conveying paths a feed section 26a and a path-leading section 26b. Relative to the longitudinal axes of the two conveying paths, which at the same time correspond to the respective conveying directions 28a, 28b, the feed section 26a and the wegführende section 26b at an angle of preferably 30 ° <γ <60 °, preferably at least approximately 45 ° to each other. In other embodiments, the feed section 26a and the wegführende section 26b may also be aligned at a different angle to each other, in particular also aligned with each other. An angle of about 45 ° allows the most space-saving arrangement of Umreifungsanlage including their conveyor. Both sections 26a, 26b can in principle be designed with any conveyor technology with which pallets can be transported. In the exemplary embodiment of the illustrated Fig. 2 the sections 26a, 26b are formed as roller tracks.

Between the feed and leading away from the Umreifungsportal 27 section 26a, 26b is a turntable 29, with a storage area 30 which is provided for the arrangement of a pallet 6. The turntable 29 may in particular have a circular storage area 30, wherein a diameter of the storage area 30 corresponds approximately to at least the length of a diagonal between two corners of the pallet 6 or greater than such a diagonal. By a conveying movement of the feed section 26a of the conveyor system 26, a pallet 6 is conveyed onto the turntable 29 with piece goods arranged thereon. The turntable 29 is provided with a rotary drive, not shown, by means of which the Rotation position of the shelf 30 and thus the respectively arranged thereon pallet 6 is changeable.

The Umreifungsportal 27 arranged in the region of the turntable 29 is provided with a tape guide ring 32 having a channel-like tape guide for the strapping. The tape guide ring 32 in this case has an upper horizontally and rectilinearly aligned portion 32a of the tape guide. As in the plan view of Fig. 3 it can be seen, the upper portion extends over the turntable 29 and the pallet 6, wherein - viewed in a projection on the turntable 29 and based on a parallel to the upper portion 32a extending diameter line 29a of the shelf 30 - the upper portion 32a of the tape guide over a closer to Umreifungsportal located (imaginary) half of the turntable 29 runs. Like also in Fig. 3 can be seen, the upper portion 32a of the tape guide is interrupted by a closure head 33. The closure head 33 is located - seen in the tape direction - slightly outside the middle of the upper portion 32a of the tape guide and interrupts this. The closure head 33 may in this case be formed in a manner known per se. Suitable closure heads 33 are, for example, those offered by the Applicant under the name ORT 230 or ORH 6500. The closure head 33 is provided with feed means for advancing the stored on a supply roll 36 Umreifungsbands 35 in the band guide channel, with clamping means for applying a tape tension on the strapping 35, with closure means for connecting two sections superimposed tape layers of Umreifungsbands 35 in the band channel, and with cutting means for separation a Bandumreifung provided by the wound on the roll 36 tape supply of the strapping. In addition, the strapping system has a carriage 34, on which the closure head 33 is mounted, drive means for lowering the closure head 33 in the direction of the shelf or pallet 6 and for the return movement of the closure head to its initial position between the upper portion 32a of the tape guide.

At its two ends, the horizontal upper section 32a of the tape guide merges into two short corner sections 32b, which are short in its movement within the tape guide ring 32, as compared to the upper section. At Each of the corner sections 32b is adjoined in each case by a rectilinearly extending lateral section 32c of the band guide ring 32. The two spaced-apart lateral sections 32c are aligned obliquely downwards, ie inclined with respect to a vertical. The spatial orientation of the slope is in this case made such that the distance between the two lateral portions 32c remains constant over its entire length, the lateral portions 32c seen from top to bottom, are inclined away from the previously defined diameter line of the turntable. Relative to a vertical extending through the ends of the upper portion 32a of the tape guide vertical, the lateral portions 32c of the tape guide ring with the vertical in each case an angle of 10 ° <φ <40 °, preferably with 15 ° <φ <30 °, a. In the exemplary embodiment, the angle φ is at least approximately 20 °.

The lateral portions 32c terminate at their lower ends in each case in one of two horizontally oriented and parallel to its longitudinal extent extending lances 32d, which, like the other constituents of the band guide ring 32, are provided with a band guide channel. The two lances 32d are located at a small distance above the shelf 30 of the turntable 29. The two lances 32d are mirror-symmetrical to each other and can be moved from an open position to a closed position and back. In the in the Fig. 2 shown open position, they have a distance from each other, through which they release the turntable 29 for an arrangement of a pallet 6 on the shelf 30. In the closed position, the two mutually facing ends of the lances 32d abut each other, so that the two lances 32d together form a lower portion of the tape guide. The lower portion of the tape guide is parallel to the upper portion 32 a and offset to this on the turntable 29th

For producing the strapping arrangement according to the invention for the in Fig. 1 shown transport unit, the four bung casks 2-5 are first placed on the pallet 6, so that touching each other adjacent barrels 2-5. Thereafter, the common horizontal strapping 14 is placed just above the upper covenant 2c-5c around the barrels 2-5, with which each of the barrels 2-5 is provided. The horizontal strapping 14 can with a PET tape with the masses 16 x 0.1 mm be executed and attached to the cargo. Subsequently, the pallet 6 is transported with the barrels arranged thereon by means of the Zuführabschnitts 26 a of the conveyor to the turntable 29. The pallet 6 is here with two of its parallel opposite side edges 6a parallel to the feeding direction 28a, the two remaining other side edges of the pallet, however, are aligned perpendicular to the feeding direction 28a. The pallet 6 is due to the conveying movement of the feed section 26a to the storage area 30. The latter has self-propelled, but not shown in the figures, roller conveyors, inter alia, to completely move the pallet on the shelf 30. Once the pallet is completely placed on the shelf 30, the pallet comes to a halt. Fig. 2 shows this situation.

The pallet 6 thus has on the shelf 30 initially the same orientation that they had on the Zuführabschnitt 26 a. It protrudes on the shelf 30 with one of its corners 6c into the (imaginary) connection line of the lances 32d of the lower tape guide, which are still being pulled apart at this time. Now the lances 32d are moved together. Here, the lances drive 32d above the shelf 30 and below the layer 8 through the pallet 6 therethrough. Since the two side edges 6a, 6b of the pallet pointing to the lances 32d are each arranged at an angle of approximately 45 °, one lance 32d passes through an opening 10 of the pallet foot and the other lance enters between the opening 11 formed by two pallet feet , The front, ie the mutually facing, ends of the lances 32d meet after they have traveled approximately the same path lengths, below the arranged in the region of the front corner 6c barrel 2 to each other. Now the tape guide ring 32 and thus its channel-like tape guide is closed in itself. The end of the wound on the supply roll 36 strapping 35 is located in the closure head 33. Now can be turned on as a feed means of the feed drive of the closure head 33, whereby the strapping tape is shot from the closure head through the tape guide channel. After the end of the belt 35 has passed through the tape guide channel this passes back into the closure head 33. Here, the tape end is now clamped in the closure head 33 and the feed drive turned off. In the area of the band end, the strapping band is now arranged in two layers. Subsequently, the closure head 33 is lowered in a vertical direction downwards in the direction of the barrel 2, as well this in Fig. 4a is shown in principle, so that the closure head 33 is disposed immediately after lowering over the upper end surface 2a of the barrel 2. Now, the feed drive is driven in the reverse direction, whereby the strap 35 exits the belt guide channel and to the barrel 2 and to the bottom of the pallet 6 in the form of a second strapping 15 as in Fig. 1 shown, applies. On the strap 35 here a tape tension has been applied. Thereafter, by means of the closure head 33, a friction welding is preferably also produced on the two band ends superimposed in the closure head 33 by means of a friction welding device integrated in the closure head 33 as a band closure. In other embodiments of the invention, other types of closure or connections may be provided, in particular other welding closures such as closures produced by tongue welding. Likewise, as connections of band ends of a strapping closure sleeves may be provided.

Subsequently, the band 35 can be released again by the closure head 33, whereby it also rests against the barrel 2 in the region of the closure head 33. After the closure head 33 is raised back to its original position and the lances 32d are also retracted from the pallet to their original position, the first of the second strapping 15 is produced. The course of the strapping band 35 of this finished strapping is previously associated with Fig. 1 been described.

Subsequently, in principle, the same way every other barrel 3-5 are provided with a second strapping 15. For this purpose, the turntable 29, based on the illustration Fig. 2 are rotated clockwise by 90 ° about its vertical axis of rotation, which passes through the center of the circular shelf 30. As a result, the next corner of the pallet 6 in the direction of rotation of the turntable 29 comes as exactly as possible into the same position in which the first corner 6c was previously located when first mounting a second strapping. This also comes in the range of this corner on the pallet 6 arranged barrel 3 on the turntable and also with respect to the Umreifungsportal 27, to the same place where previously the barrel 2 was during the attachment of his second strapping 15. Now that the Pallet 6 and the barrel 3 are arranged correctly under the strapping 27, can now be started with the attachment of the second strapping 16 for the barrel 3. Here, exactly the same tape strapping cycle using the same means and the same procedure as the second strapping 15 is previously applied. This involves closing the tape guide ring by inserting the two lances 32d in the region of the corner under the pallet 6, wherein the one lance 32d is inserted from one side edge and the other lance 32d from the other side edge under the position 8 of the pallet. Subsequently, the unwinding of the tape 35 from the supply roll 36 and a shooting of the unrolled tape 35 through the channel of the tape guide ring 32, including the clamping of the tape end in the closure head 33, whereby the tape is arranged in sections with two superimposed layers in the closure head. After the closure head 33 is then lowered directly over the upper end face of the drum 4, the next second strapping 15 can be produced by retraction of the belt 35, local welding of two belt layers of the belt, as well as separation of the belt strapping from the supply roll 36. Again, the course of the band of the second strapping 15 corresponds to the representation of Fig. 1 and the associated description.

After now the second of the second strapping 15 and thus the barrel 3 is secured by means of this second strapping 15 and the horizontal strapping 14 on the pallet 6, first by another rotation of the pallet 6 about the axis of rotation of the turntable by 90 °, the range positioned for the third of the second strapping 17. After positioning is also here in the direction of rotation following corner of the pallet 6 in the in Fig. 2 shown position. This situation is in Fig. 2a . 3a and 4a shown.

Now the Umreifungszyklus for the third barrel 4 can be performed according to the two cycles described above. After this is done, the pallet 6 is further rotated by a further clocking of the turntable by 90 ° in the same direction as before, so that even the only remaining fourth corner of the pallet 6 and the fourth barrel 5 spent in the same Umreifungsposition becomes.

After also around the last fourth drum 5 a strapping 18 of the second type attached and this is also attached to the pallet, and the lances 32d have moved out of the range, the transport unit is completed. Now the pallet 6 with its drums can be transported away from the strapping system 25 via the carrying away section 26b of the conveyor 26 and is ready for shipment as a transport unit. Here, the pallet is pushed by means of the driven rollers of the turntable 29, or the storage surface 30, on the turntable adjacent wegführenden portion 26 b of the conveyor 26, detected by the driven rollers of the wegführenden portion 26 b and leads away from the strapping.

Of course, in other embodiments, either the turntable can also be rotated in the counterclockwise direction or else the positions of the pallet can be generated in a different way than by a (pure) rotary movement. It is also possible that the strapping machine rotates around the pallet and instead of a turntable a rotatably arranged table is provided. Finally, in other embodiments of the invention, at least one of the two strapping types, preferably all strapping, can also be produced with a strapping tool.
