Description

Technical Field

[0001] The present invention relates to a device for turning over a rolled container and a method for turning over a rolled container. Background Art

[0002] Roll containers are rolling vehicles, such as transport carts, container carts, and hand trucks. Roll containers can be stacked. Stacking roll containers can be particularly space-saving if the top roll container is tipped over or flipped over before being placed on the next roll container. This is also known as rotation stacking. This can be problematic if the roll container is too heavy to flip manually. For this purpose, devices are known, such as lifting mechanisms that can grip, lift, rotate, and release roll containers. Improvements are needed in devices and methods for performing rotation stacking. Summary of the Invention

[0003] In this regard, an object of the present invention is to provide a device or method to reduce the cost of turning over and improve ergonomic design.

[0004] This object is achieved by a device for turning over rolling containers and for fastening to the forks of a floor conveyor, in particular a lift truck, a loading and unloading truck and / or a forklift. According to the proposal, the device comprises a fastening section for fastening to the fork tines and a rotating section rotatably or pivotally mounted on the fastening section, wherein the rotating section has two fork-shaped elements for engaging in the bottom section of the rolling container or for forking the bottom section.

[0005] It can be provided that the distance between the two fork elements and the length of the two fork elements are set and the length is at least twice the distance.Alternatively or additionally it is provided that the rotating section has a spacing element for spacing the two fork elements from the ground or floor.

[0006] In other words, for example, a device is proposed that can be placed on a lifting tool by a loading and unloading vehicle, a loading and unloading forklift and / or a lifting vehicle and is provided or designed for overturning rolling containers, such as container carts. The device has a section for being fastened to the lifting tool. The device has another section that has a fork or at least two protrusions so as to engage with the rolling container. The two sections are fastened to each other in a rotatable / rotatable manner, so that a rotatable fork is basically obtained for a lifting tool that is usually not rotatable. In particular, the present invention is outstanding in that the protrusions forming the fork can be as close to each other as possible, for example, the gap between these protrusions is at least half of its length. It is also possible that the other section has a protrusion so that its fork is spaced apart from the floor or reaches the correct height of the rolling container.

[0007] The present invention advantageously realizes the concept of a device that is extremely space-saving and can be attached to typical logistics equipment with forks (conventionally, floor conveyors such as forklifts, forklifts, and lift trucks) and thus used to tilt rolling containers. In this respect, the device is a cost-effective, low-maintenance, and ergonomic aid for tilting rolling containers. Despite the space-saving device, it remains secure during tilting by being fastened to the forks during use.

[0008] A ground conveyor or ground transport vehicle is a conveying means for transporting goods at least substantially horizontally on flat ground. The ground conveyor considered here has a fork or tines. The ground conveyor can in particular travel or move on the ground. The ground conveyor can be a lift truck, a loading and unloading cart, a multi-directional loading and unloading cart, a narrow-aisle loading and unloading cart, a balanced loading and unloading cart, a horizontal sorting cart, a vertical sorting cart, a loading and unloading forklift and / or other ground transport vehicles mentioned in the VDI guideline VDI 3586 of September 2022. The ground conveyor typically has two tines, with which goods or pallets can be forked and raised. The tines can be adjusted at least up and down. These tines regularly extend at least substantially parallel and spaced apart from each other so that they can be pushed under or into the pallet and can engage the pallet or articles from below at a corresponding distance and stably lift them.

[0009] The fastening section can be understood as a part of the device that is provided for fastening to the fork tines. The fastening section can have a metal (in particular steel and / or aluminum) or be made thereof. The fastening section can be a welded structure so that it is stable. The fastening section can be designed to be placed on the ground (in particular independently of the fork tines, and in particular together with the rotating section), for example in order to be able to be easily lifted or forked again later by a ground conveyor. The fastening section can have one or more feet for placing on the ground. Alternatively or in addition, a spacer element can be provided for or suitable for being placed on the ground. The fastening section can have a rotary bearing or a part of a rotary bearing so as to be rotatably connected to the rotating section.

[0010] The rotating section can be understood as a (further) part of the device that can rotate relative to the fastening section. The rotating section can have a metal (especially steel and / or aluminum) or be made thereof. The rotating section can be a welded structure (especially comprising a fork element, a bracket and / or a spacer element) so as to be stable. The rotating section can be designed to be placed on the ground (especially independently of the fork tines and especially together with the fastening section). The rotating section can have one or more feet for being placed on the ground. Alternatively or in addition, a spacer element can be provided for or suitable for being placed on the ground. The rotating section can have a rotary bearing or a part of a rotary bearing so as to be rotatably connected to the fastening section.

[0011] The rotating section is fixed to the fastening section, in particular so as to be rotatable, rotatable, or pivotable about the rotation axis. For this purpose, a rotary bearing may be provided. The rotary bearing may include a shaft guided in a bushing or multiple bushings. The rotary bearing may include a rolling bearing or multiple such rolling bearings. The rotary bearing may include a sliding bearing or multiple such sliding bearings, in particular plastic sliding bearings. The rotary bearing preferably secures the rotating section and the fastening section to each other in the axial direction or along the rotation axis. Preferably, the rotating section can rotate back and forth at least one full revolution. Further preferably, the rotating section can rotate back and forth at least half a revolution. In particular, the rotating section can rotate back and forth several revolutions. It is also conceivable that the rotating section can rotate only in one direction, while being locked (optionally selectively locked) in the other direction. A locking device may also be provided that selectively locks the rotating section relative to the fastening section to prevent rotation, for example, when the rolling container is forked and lifted to prevent it from accidentally tipping over.

[0012] The distance between the two fork-shaped elements can be understood as being transverse or perpendicular to the length or extension direction of the fork-shaped elements. The length can preferably be understood as being along the main extension direction of the fork-shaped elements. The length preferably extends away from the fastening section and / or along the axis of rotation about which the rotating section can rotate. Finally, according to the proposed design of the present invention, the fork-shaped elements should be significantly closer to each other, rather than extending in length, to achieve stable engagement or stable forking.

[0013] The spacer element is preferably a section to which the rotating section is fastened or formed. It is proposed that the spacer element has the purpose of keeping the fork element off the ground or at a predetermined / correct height for picking up the rolling container. The spacer element can also be understood as a foot. The length of the spacer element can be adjustable.

[0014] The rolling container preferably has a bottom section and at least two opposing wall sections. The wall sections are preferably arranged at least substantially parallel to each other. The wall section is preferably adjacent to or fixed to the bottom section. The wall section faces away from the bottom section at least substantially vertically. Rollers, for example pivotable or follower rollers, in particular four rollers, may be provided on the bottom side (in particular fixed to the bottom section). The wall section and the bottom section may be arranged in a U-shape. In this respect, two rolling containers can be easily rotated and stacked, because the U-shape can be engaged into each other. The bottom section may have a grille and / or have or be made of plastic to save weight.

[0015] The rolling container is preferably provided with one or more (for example two) engaging openings in the area of ​​the bottom section or at the bottom section. The engaging openings can be arranged adjacent to each other. The engaging openings are provided for fork tines or fork-shaped elements, i.e. for engaging or embedding them. A middle web can be arranged between the two engaging openings. The middle web can separate the engaging openings from each other and provide stability. Preferably, a plurality of engaging openings or middle webs are provided on both sides of the bottom section or flushly oppositely, so that the rolling container can be forked on both sides and / or can be forked from both sides of the rolling container through all engaging openings. The engaging openings and / or middle webs are preferably formed by one or more frame elements at the bottom section of the rolling container or by the bottom section itself.

[0016] The device can advantageously be modified so that the length (of the two fork-shaped elements) is at least 20 cm. Preferably, the length is at least 40 cm, 50 cm or 60 cm. In particular, the length is 90 cm ± 20 cm. The length is preferably at most 150 cm or 120 cm. The two fork-shaped elements are preferably the same length and / or are designed to have the same cross-section. The two fork-shaped elements are preferably long enough to extend beyond the bottom section of the rolling container on both sides; therefore, a typical length is at least 60 cm or at least 80 cm, in particular at least 10% greater than 60 cm or 80 cm. The two fork-shaped elements are preferably elongated and / or rod-shaped. Preferably, the two fork-shaped elements are metal parts and / or metal profiles, such as circular profiles and / or polygonal profiles, in particular quadrilateral profiles. In particular, the two fork-shaped elements are hollow to save weight. The two fork-shaped elements are advantageously longer than the rolling container so that these fork-shaped elements can extend through the rolling container. A good compromise can thus be achieved between maintaining stability when rolling the container and the overhanging weight of the device, with the device being as compact as possible.

[0017] Alternatively or in addition, it can be proposed that the distance (between the two fork-shaped elements) is at most 20 cm. Preferably, this distance is at least 1 cm or at least 5 cm. This distance can advantageously be set to at most or less than 15 cm or 10 cm, in particular this distance is 7.5 cm ± 5 cm. The two fork-shaped elements preferably extend at least substantially parallel and / or side by side with each other. This distance is preferably at a plurality of positions between the two fork-shaped elements. Thus, a good compromise can be achieved between the stability when the container is being rolled and the overhanging weight of the device, wherein the device is as compact as possible.

[0018] The width of the two fork-shaped elements can be adjusted. Preferably, the two fork-shaped elements are of the same width. In particular, the width corresponds to at least half the distance. The width can also be up to four times, three times, or twice the distance, or even greater. In particular, the width lies in the range of at least half to twice the distance. This provides a compromise between the stability of the container when it is being rolled, the stability of the device itself, and the overhanging weight of the device. This also has a positive impact on the compactness of the device.

[0019] The two fork-shaped elements can each have an inclined surface and / or form an inlet for the rolling container. The respective inclined surfaces can be arranged on the end faces of the respective fork-shaped elements. The inclined surfaces of the two fork-shaped elements can face each other. These inclined surfaces can form an inlet for the rolling container, in particular for the central tab on the rolling container. This simplifies ergonomics and allows the rolling container to be turned more quickly.

[0020] Two additional fork-shaped elements can be provided to engage in the bottom section of the rolling container. These two additional fork-shaped elements can be designed basically like these two fork-shaped elements, that is, for example, designed to be similar or identical with respect to size and / or any other preferred features. These two additional fork-shaped elements can be arranged relative to the two fork-shaped elements with respect to the axis of rotation of the rotating section. For example, the rotary bearing is basically centered between these two fork-shaped elements and these two additional fork-shaped elements. These two additional fork-shaped elements and these two fork-shaped elements are preferably arranged at least basically parallel to each other. In particular, two, three or all of these fork-shaped elements are arranged at least basically parallel to each other. These two additional fork-shaped elements and these two fork-shaped elements can provide a U-shaped shape of the rotating section or be arranged into a U-shape.

[0021] The two fork-shaped elements and optionally the two other fork-shaped elements can be arranged to be spaced apart from the rotation axis of the rotating section. In particular, the two fork-shaped elements and optionally the two other fork-shaped elements are arranged or oriented to be at least substantially parallel to the rotation axis. For example, the distance from the rotation axis is at least 10 cm, preferably at least 15 cm. The two fork-shaped elements and optionally the two other fork-shaped elements can rotate eccentrically or eccentrically around the rotation axis of the rotating section or rotate together with the rotating section. This is advantageously arranged so that when the fork-shaped elements engage in the bottom section, the rotation axis is shifted toward the center of gravity of the rolling container and / or is arranged to be spaced apart from the bottom section.

[0022] The two fork-shaped elements and the two other fork-shaped elements can have another distance from each other. This other distance can be at least 5 cm, preferably at least 10 cm. Further preferably, this other distance is at least 15 cm and in particular 20 cm ± 10 cm or 40 cm ± 20 cm. This other distance can be less than the length (i.e., in particular the length of the two (other) fork-shaped elements), for example 25% or 50% less than the length. This also provides advantageous compactness while improving functionality and ergonomics. The two other fork-shaped elements can achieve faster turning over, because the rotating section can be used again immediately after turning over, without having to rotate back. This also ensures that the rolling container can be rotated more easily, because the rolling container can tend to be rotated around its center of gravity or at least close to its center of gravity.

[0023] The rotating section can have a bracket that is rotatably or pivotally supported on the fastening section. The two fork-shaped elements and / or the two further fork-shaped elements can be fastened to the bracket, for example, to provide a U-shaped configuration with the bracket. The fork-shaped elements can be welded to the bracket to provide a particularly stable, loss-proof, and therefore reliable and low-maintenance structure. The bracket preferably extends transversely, in particular substantially perpendicularly, to the axis of rotation.

[0024] The distance between the rotating section, in particular the bracket, and the fastening section can be at least 5 cm, preferably at least 10 cm. This distance can be provided by the rotary bearing. This distance exists, in particular, when viewed parallel to the axis of rotation. This distance advantageously reduces the risk of crushing the rotatable component.

[0025] It is possible that the support has or provides a spacer element, in particular two opposing spacer elements. The spacer elements are preferably provided so that the fork-shaped element is fixed to the support along the support, spaced apart from the free end of the support; in this respect, the spacer elements remain as an overhanging section of the support. The support is advantageously an elongated and / or rod-shaped component, such as a metal component and / or a metal profile, such as a circular profile and / or a polygonal profile, in particular a quadrilateral profile, so that a stable holder for the fork-shaped element and, if necessary, an additional spacer element can be obtained in a coordinated and structurally simple manner. In particular, the support is hollow to save weight. Preferably, in the case of two spacer elements, the spacer elements are oriented parallel to each other and / or pointing away from each other or in other / opposite directions. This allows the device to be flexibly turned into two rotational positions and the height of the device above the ground to be easily adjusted depending on the spacer elements, without having to rotate the device back for the next rolling container after the first turning of the first rolling container.

[0026] The spacing element can have floor rollers, wherein the floor roller axis (i.e., the axis about which the floor roller can rotate when rolling on the ground) can be arranged transversely to the rotation axis of the rotation section. The floor rollers are in particular load-bearing rollers. A plurality of floor rollers or load-bearing rollers can also be provided, for example, two such rollers can be arranged side by side and / or coaxially. Particularly advantageously, the floor rollers can be integrated into the spacing element. The floor rollers can extend from the spacing element by a section. The floor roller axis or the floor rollers can be mounted in the bracket on both sides. Thus, a hollow bracket provided with the spacing element can also accommodate and / or store floor rollers with minimal complexity. It is also possible for the spacing element itself to consist of a hollow component, so that it can also be equipped with floor rollers in a simple manner.

[0027] Preferably, if the two spacer elements each have one, two or more floor rollers, these floor rollers are oriented so as to point away from one another or in opposite directions, in particular with at least substantially parallel floor roller axes. Thus, the device can be flexibly tilted into two rotational positions and the device can be displaced along the floor surface with low resistance by relying on the floor rollers, without having to rotate the device back after the first tilting of the first rolling container for the next rolling container.

[0028] The floor rollers may be adjustable, in particular for adjusting the effective length of the spacing element and / or the spacing between the fork element and the floor. For example, the spacing element may be adjusted away from or toward the axis of rotation. For example, different rolling containers may have different spacings between the engagement opening and the floor. The adjustability of the floor rollers and / or spacing element ensures that the device is adaptable to different rolling containers.

[0029] The fastening section can have an insert for the tines. Multiple, preferably two, inserts can also be provided, arranged to extend, in particular, side by side and / or at least substantially parallel to one another. Preferably, one insert is provided for one or both of the tines, or one insert is provided for each tine, i.e., specifically designed to create a form fit in at least one direction. In other words, one insert can be provided for each tine, or one insert can be provided for both tines. An insert can be understood, in particular, as a receptacle or recess for inserting / pushing one or more tines. The insert is preferably oriented along the axis of rotation of the rotating section. In this regard, one or both tines can be pushed into the insert or inserts along the axis of rotation, in particular parallel to the axis of rotation. Using this insert or inserts, a particularly user-friendly and error-resistant method for fastening the device to a floor conveyor, such as a forklift, loading and unloading truck, and / or forklift, is provided. A user who is familiar with the operation of the floor conveyor can then immediately recognize whether the tines have been pushed correctly or incorrectly into the device (if there is a specific insertion portion for this).

[0030] The fastening section can also be provided with a fastening device. It can also be provided with multiple fastening devices. For example, one or more fastening devices can be provided for each fork tine. A fastening device can also be provided, or multiple such fastening devices can be provided, which are provided for two fork tines. The fastening device can releasably fasten the fastening section to the fork tine. For example, the fastening device has a mechanism for reversibly or releasably clamping the fork tine and / or producing a form fit with the fork tine, in particular acting along the axis of rotation. The fastening device can have a bolt, for example, which is designed to releasably clamp the fork tine pushed into the insertion part. The fastening device or bolt can be adjusted or tightened, for example, transversely to the insertion part, the axis of rotation and / or the fork tine and pointing towards the insertion part and / or the fork tine. The fastening device is particularly designed to provide a releasable force fit and / or form fit between the fastening section and the fork tine. Particularly advantageously, the fastening device is designed to releasably clamp at least one clamping member to one or both tines from the bottom side of the tines. For example, the clamping member can be adjusted by tightening the fastening device, and in particular (preferably from below) is clamped to the tines in order to clamp the fastening section. "Clamping on the bottom side" has the following advantages: the fastening section fastened to the top side of the tines remains essentially on a plane, and in this respect, the device occupies the same angle relative to the tines at each tightening. This makes it possible to accommodate rolling containers as easily as possible, and reduces the risk of the fork-shaped element tilting during the introduction process. In this regard, a particularly reliable and still easy-to-operate fastening to the ground conveyor is provided. Therefore, the position or inclination of the device on the tines is the same at each tightening, so that the rotation axis of the rotating section is always oriented as identically as possible with the ground or the tines. This is important and advantageous so that the fork-shaped element can be well introduced into the coupling opening of the rolling container.

[0031] A method for flipping a rolling container is also proposed. In particular, in this method using a ground conveyor, a device (preferably the device described herein) fastened to the tines of the ground conveyor is pushed into the bottom section of the rolling container, wherein the device at least partially or temporarily contacts the ground and / or rolls on the ground, the device is lifted together with the rolling container, and the rolling container and preferably the rotating section of the device are rotated or flipped, in particular substantially parallel to the ground and / or the tines and / or about the rotation axis of the device. In this case, the rolling container is rotated or flipped, in particular, by approximately 180°. The rolling container can then be placed into another rolling container. The device can then be pulled out of the bottom section or the coupling opening. This allows pairs of rotating stacked rolling containers to be provided. It can be provided that the two rotating stacked rolling containers are releasably secured to each other, for example, using a belt device or an elongated fastening device. In particular, two adjacent wall sections of the rotating stacked rolling containers are secured to each other.

[0032] The invention also proposes the use of the device for turning over rolling containers. The rolling container can be designed as described in the present invention. The rolling container preferably has a bottom section, a wall section extending at least substantially perpendicularly from the bottom section, or two wall sections arranged opposite each other. The rolling container preferably has at least one connection opening, in particular two connection openings, in the bottom section. Furthermore, a system comprising the device and one or more rolling containers and / or a factory truck is proposed.

[0082] exist Figure 1 In the figure, two rotating stacked rolling containers 200 are shown, which are particularly known as mail container carts. Or it may be designed as such a mail container cart. Each of these rolling containers 200 has a bottom section 202 and two opposing wall sections 204. The wall sections 204 are adjacent to the bottom section 202 and extend at least substantially perpendicular thereto. The wall sections 204 and the bottom section 202 are arranged in a U-shape. This allows the rolling containers 200 to be easily rotated and stacked, as the U-shaped configuration allows them to fit into one another. The two rolling containers 200 are secured to each other using a belt.

[0083] The respective bottom section 202 has two adjacent engagement openings 206 (e.g., for fork tines or fork-shaped elements). These engagement openings are separated from one another by a central web 208. The engagement openings 206 and the central web 208 are located on opposite sides of the bottom section 202 or flush with one another, so that the rolling container 200 can be lifted from both sides. The engagement openings 206 are formed by one or more frame elements on the bottom section 202 of the rolling container 200.

[0084] Each rolling container 200 has a center of gravity axis S, which is located above the bottom section 202 and substantially centrally between the wall sections 204. The center of gravity axis S is typically less than half the height of the rolling container 200. The center of gravity axis S extends through the center of mass of the rolling container 200. Tumbling the rolling container 200 substantially around the center of gravity axis S requires less effort. The present invention is particularly intended to provide an ergonomically advantageous solution in the embodiments described below and illustrated in the accompanying drawings.

[0085] Figures 2A to 2B A device 2 is shown for turning over a rolling container 200, in particular Figure 1 One of the rolling containers 200 is used to be fastened to the fork tine 102 of the ground conveyor 100. Figure 2A In FIG, the device 2 is placed on the ground B on its feet 19 and the spacing elements 34. Figure 2B In FIG. 1 , the device 2 is fastened to the tines 102 of the ground conveyor 100 shown there and is lifted.

[0086] The device 2 is at least partially a welded structure. It is coated and / or painted for corrosion protection. The device 2 includes a fastening section 10 for fastening to the fork tines 102 and a rotating section 20 rotatably supported on the fastening section 10 about a rotation axis Z via a rotary bearing 16 . The rotating section 20 has two fork-shaped elements 22 for engaging with the bottom section 202 of the rolling container 200 .

[0087] In device 2 , a distance 26 between the two fork-shaped elements 22 and a length 28 of the two fork-shaped elements 22 are provided, and length 28 is at least twice as great as distance 26 . Here, length 28 is several times greater than distance 26 , in particular at least five or ten times greater. Length 28 is at least 20 cm, and distance 26 is at most 10 cm. The width 25 of the two fork-shaped elements 22 is in the range from at least half to twice as great as distance 26 .

[0088] In addition to the two fork-shaped elements 22, two further fork-shaped elements 24 are provided for engaging in the bottom section 202 of the roll container 200. The two further fork-shaped elements 24 are designed similarly to the two fork-shaped elements 22 in terms of size.

[0089] The additional fork-shaped element 24 is opposite the two fork-shaped elements 22 with respect to the rotation axis Z. The rotation axis Z extends centrally between the fork-shaped elements 22, 24 and extends at least substantially parallel to the fork-shaped elements. The fork-shaped element 22 and the additional fork-shaped element 24 are separated by a further distance 30 from each other, which is less than the length 28 and is at least 20 cm. Therefore, the fork-shaped elements 22 and 24 are derived from the rotation axis Z because the center of mass or gravity axis S of the rolling container 200 is substantially located there. This makes it easier to turn the rolling container 200 around the horizontal axis; otherwise, the rolling container 200 might not be able to rotate so easily. The fork-shaped elements 22, 24 are each a hollow or square profile made of metal, more precisely, steel.

[0090] The rotating section 20 has a support 32 to which the fork elements 22 and 24 are fixed or welded. The support 32 forms part of the rotary bearing 16 and is rotatably or pivotally supported on the fastening section 10. The rotary bearing 16 has a shaft 16.1 guided in a bushing 16.2 on the fastening section 10, see also Figure 4B The shaft 16.1 is fixed in a rotationally fixed manner on the rotating section 20 or the bracket 32, and the bushing 16.2 is fixed on the fastening section 10. The bracket 32 ​​is at least partially a hollow or square profile comprising or consisting of metal, in particular steel and / or aluminum.

[0091] The rotating section 20 has two of the spacing elements 34 for spacing the two fork-shaped elements 22 from the ground B. In this case, the support 32 has the spacing elements 34 as spacing elements 34 pointing in opposite directions or away from each other or in opposite directions, or is shaped as such. The fastening section 10 also has feet 19 for placement. Thus, the device 2 can be placed on the ground B in conjunction with one of the spacing elements 34, see Figure 2A .

[0092] The two fork-shaped elements 22 each have a bevel 40 on their end faces, more precisely facing away from the pivot bearing 16, the fastening section 10, and / or the support 32. These two bevels 40 face toward each other, in particular to form a tapering inlet for the central web 208. The bevels 40 extend substantially along the support 32 and / or, in their extension, form a cutting axis that is arranged transversely or perpendicularly to the axis of rotation Z. The two other fork-shaped elements 24 are also provided with such bevels 40.

[0093] The fastening section 10 has an insertion portion 12 for the tines 102, wherein the insertion portion 12 is oriented along the rotation axis Z. The device 2, more precisely the fastening section 10, is provided with several components of a locking device 18 in order to selectively lock the rotating section 20 against rotation at the fastening section 10. Alternatively or in addition, the rotating section 20 can have a locking device 18 or components thereof. In FIG2 , the locking device 18 has a pivotable, in particular spring-loaded or spring-loaded, pin that can engage in the rotating section 20 in at least one rotational position (here, in two rotational positions) and thus create a positive fit about the rotation axis Z. The locking device 18 or the pin is, in particular, pivotable transversely to the rotation axis Z.

[0094] The locking device 18, in particular the pin, can be manually released from the positive fit in order to enable the rotation of the rotating section 20. For example, the pivotable pin can be pressed downward at its free end to release the positive fit at the opposite end. The locking device 18 can then, in particular when it is released again, be spring-loaded to reestablish the positive fit in the corresponding rotational position.

[0095] Here, the fastening section 10 has a fastening device 15, which can act on the two fork teeth 102 and clamp them. Thus, the device 2 can be releasably fastened to the ground conveyor 100, such as Figure 2B Or there are Figure 3B shown.

[0096] Figures 3A to 3E The device 2 shown in FIG is designed essentially or at least partially like the device of FIG. 2 . In this respect, the description of FIG. 2 applies correspondingly to Figures 3A to 3E . To supplement this, Figures 3A to 3E The device 2 is equipped with an insert 12 and an adjacent insert 14 for each fork tine 102, i.e. two inserts 12 and 14. This also improves the lateral guidance of the fork tine 102. Figures 3A to 3E Another difference between the two should be mentioned: in FIG2 , the bracket 32 ​​is essentially X-shaped or cross-shaped, in particular in which the fork-shaped elements 22 and 24 are fixed relative to each other on the bracket 32, and in particular in which the multiple components of the locking device 18 are fixed relative to each other on the bracket 32. Figures 3A to 3E In the embodiment, the bracket 32 ​​is not X-shaped, but is only I-shaped or extends in only one direction. Figures 3A to 3E The design is more compact than that in Figure 2.

[0097] Reference Figures 3A to 3E , especially Figure 3B A variant is shown in which the spacing elements 34 each have two floor rollers 36 which are designed as load-bearing rollers, wherein the floor roller axes 38 are arranged transversely to the axis of rotation Z. The floor rollers 36 are adjustable, so that the effective length of the spacing elements 34 or the distance of the floor rollers 36 from the axis of rotation Z is variable.

[0098] exist Figures 3A to 3E In FIG. 1 , a method for turning over a roll container 200 is shown or indicated in principle step by step. Figures 3A to 3E The use of the device 2 for turning over a rolling container 200 is shown. With the aid of the floor conveyor 100, the device 2, which is fastened to the fork tine 102 of the floor conveyor 100, is pushed with two of its fork elements 22 into the bottom section 202 of the rolling container 200, see FIG. Figures 3A to 3C transition, in which Figure 3CThe middle device 2 is still only just before it is pushed in. Each of the two fork-shaped elements 22 is pushed into, inserted into, or forked over one of the engagement openings 206 of the bottom section 202. The aforementioned bevel 40 hereby causes the middle web 208 to be centered between the two fork-shaped elements 22, which then allows the rolling container 200 itself to be displaced laterally, if necessary, and thus corrected in position.

[0099] At the time of pushing in and shortly before pushing in, the device 2 is at least partially in contact with the ground surface B or rolls on the ground surface B, see Figure 3C During insertion, the support 32 of the device 2 is in particular oriented substantially perpendicularly to the ground B or vertically, see Figure 3B .

[0100] When the fork-shaped element 22 is fully pushed in, the fork-shaped element 22 extends again from the opposite engagement opening 206 on the opposite side of the rolling container 200 or the bottom section 202 , see Figure 3D In this respect, it is preferred that the fork-shaped elements 22 and 24 are longer than the bottom section 202 so as to protrude beyond the bottom section 202 on both sides. The device 2 is then also lifted together with the rolling container 200, see Figure 3D .

[0101] It is obvious that the axis of rotation Z and the axis of gravity S at least substantially coincide, in particular because the fork-shaped elements 22 and 24 are arranged eccentrically to the axis of rotation Z corresponding to the center of gravity of the rolling container 200, see Figure 3D In this respect, it is ergonomically easier to rotate the roller container 200 , since the imbalance about the axis of rotation Z is relatively small.

[0102] The locking device 18 can be released after lifting so that the rotating section 20 can be rotated or turned relative to the fastening section 10 to turn the rolling container 200. The locking device 18 can automatically snap in or form a positive fit again (for example after rotation).

[0103] The rolling container 200 and the rotating section 20 of the device 2 are essentially parallel to the ground B and the fork tines 102 and are rotated about the rotation axis Z of the device 2, see FIG. Figures 3D to 3E Subsequently, the flipped rolling container 200 can be stacked on Figure 3E Finally, the arrangement of the rotating stacked rolling containers 200 can be realized, for example, as Figure 1 As shown in .

[0104] Figure 4A and Figure 4B Each is shown essentially on the underside of the fastening section 10 Figures 3A to 3EFurther details of the equipment.

[0105] Figure 4A It shows how the fastening device 15 achieves clamping of the fork tines 102 located in the inserts 12, 14. A clamping piece 15.1 is clamped to the bottom side of the fork tines 102 by means of a screw 15.2. The screw 15.2 can be rotated by means of a manipulation means 15.3 (e.g. a lever) to adjust the clamping piece 15.1.

[0106] Figure 4B It is shown that the rotary bearing 16 has a shaft 16.1 which is guided in two bushings 16.2 spaced apart from one another along the shaft 16.1. The bushings 16.2 each have a plain bearing, in particular a plastic plain bearing.

[0107] As shown, the distance between the bushings 16 . 2 is in particular greater than the distance 29 in order to avoid excessive bending moments on the rotary bearing 16 .

[0108] It is clear that the shaft 16.1 projects from the fastening section 10 by a distance 29. The distance 29 is, for example, 10 cm ± 5 cm.

[0109] Figure 5 The device 2 for turning over a rolling container is shown. The device 2 is fastened to the fork tine 102 of the ground conveyor. The device 2 is based on Figures 3A to 3E 4 , the description of the same reference numerals applies accordingly. The device 2 is supplemented with two handles 11 . Each handle 11 is arranged in the area above one of the inserts 12 , 14 or is attached to the fastening section 10 , in particular opposite the rotation section 20 .

[0110] The handle 11 has, for example, a circular cross-section, preferably with a diameter in the range between 15 mm and 35 mm, in particular in the range between 20 mm and 30 mm.

[0111] Here, the handle 11 is preferably spaced apart from the top side of the inserts 12, 14 or the fork tines 102 at a distance 11.1 between 200 mm and 350 mm, in particular between 250 mm and 300 mm. The handle 11 can be provided with plastic, for example a plastic coating, for work protection.

[0112] The foot 19 of the device 2 is shortened relative to the spacing element 34, in particular so that when the spacing element 34 rests on the ground and the axis of rotation Z extends substantially parallel to the ground, the device 2 is spaced apart from the ground by the foot 19 during use. In this regard, a distance 19.1 exists between the spacing element 36 and the foot 19 or between the foot and the ground. This also allows the device to be tilted, similar to a wheelbarrow, and to be lifted manually by the handle 11 and thus sufficiently spaced apart from the ground by the foot 19.

[0113] In particular, the shortening of the foot 19 ensures that even suspended or tilted tines 102 (ie tines which no longer extend parallel to the ground for structural reasons or due to wear or aging) can enter the placed device 2 as collision-free as possible.

[0114] The distance 19.1 is preferably at least 5 mm and at most 80 mm, further preferably at least 15 mm and at most 60 mm, the distance 19.1 being in particular 40 mm±15 mm.
