technical field

The invention relates to a conveying device according to the features of the preamble of claim 1 .

Background technique

German Utility Model DE 20 2006 012 275.3 discloses a conveyor pallet and a conveyor device with a conveyor pallet for fences or insulating elements, wherein longitudinal beams and transverse beams form a horizontal, rectangular support Frame, wherein holding means are arranged in the support frame for plug-in accommodation of the pipe ends of the standpipes of the barrier or insulation element. Steel angles are used as longitudinal beams.

Contents of the invention

It is essential for the invention that the barrier or separating element in the central region of the conveyor pallet is arranged higher than at least one barrier or separating element which can be placed in the edge region of the conveyor pallet. Barriers or spacer elements placed in the edge region of the conveyor pallet act as side walls, which effectively prevent the retaining feet of the barrier or spacer elements that can be transported on the conveyor pallet from slipping off from the sides. The distance between the upper edge of the longitudinal beam and the lower horizontal latch of the fence or insulation element is so small that no retaining foot can be pushed into the hollow space between the longitudinal beam and the fence or insulation element. This configuration of highly offset conveyor pallets has proven to be very effective. In practice, the falling of the retaining foot is of course not only prevented by the horizontal locking pins of the barrier or the separating element, but also additionally by the upwardly raised edges in the region of the longitudinal beams. This edge is achieved by welded lap plates. The longitudinal beams were originally made of angle steel. However, it has the disadvantage that the pallet cannot be lifted in the longitudinal direction by means of the handling forks, but only in the transverse direction. Therefore, the longitudinal beams are replaced by rectangular tubes adapted to accommodate the handling forks. Due to the omission of the upwardly pointing edge of the angle bar, welded lap webs are necessary in the case of rectangular tubes.

The necessity of such an edge results from the fact that the lower ends of the pipe ends stand upright on the transport frame. Since in this case the lower edge of the barrier or the separating element lies within the height of the second level of the retaining feet, the lower retaining feet must pass over this edge to prevent falls. Under certain operating conditions, this side edge is in the way. Although this edge is out of the way when the transfer pallet is placed on level ground and only the holding feet need to be lifted. But sometimes the transfer pallet is located on the loading surface of the truck. In this case, the individual holding feet have to be easily lifted to the height of the worker's chest and pulled over the edge. This is much more difficult than lifting the stone from the lower teleportation pallet. Due to the relatively heavy holding foot, there is at least a theoretical risk of injury.

It is therefore the object of the present invention to improve the conveyor device according to the features of the preamble of claim 1 in such a way that the loading and unloading of the conveyor pallets is improved and thus the risk of injury is avoided.

This object is achieved by a conveyor device according to the features of claim 1 .

Advantageous developments of the idea of the invention are the subject matter of the subclaims.

It is important that the pipe ends of the gratings or spacer elements arranged on the edges of the conveyor pallets engage in the pockets arranged on the sides of the longitudinal beams. Due to the pockets arranged on the sides, the pipe ends of the standpipes are no longer located on the support frame and therefore not at the level of the bottom of the pallet, but in pockets next to the support frame. Therefore, the fence or spacer element that is arranged on the edge can be positioned deeper than all other fences or spacer elements on the conveying pallet, and as a result, its lower edge not only fixes the upper layer of the retaining foot on the conveying pallet, There is even a fixed lower layer to hold the feet. As a result, the hitherto necessary edges (for example flat steel) can be dispensed with without replacement.

As a result, the holding feet can be pushed very easily onto the flat pallet bottom, even if the transfer pallet is arranged higher and, for example, on the loading surface of a truck. Loading of transfer pallets is just as easy, as is unloading. It is only necessary to remove the barriers or spacer elements arranged on the edges in order to catch all layers of the holding feet overlapping one above the other without hindrance in height.

By virtue of the pockets arranged at the sides, angle irons or flat irons protruding upwards in the edge region of the conveyor pallet can be completely dispensed with. Hitherto, such edge members have been necessary over the entire length of the conveyor pallet. Correspondingly, the welding work is massive. In the solution according to the invention, only two pockets need to be provided on the sides of the longitudinal beams. The welds used to fasten the bag are substantially shorter overall than the welds used to fasten angle or flat bars.

In an advantageous development, the holding device is detachably or non-detachably connected to the support frame. Thus, the releasable holding device can be eliminated during empty transport and when storing transport pallets, in order to reduce accidents and save transport or storage capacity.

In particular, the holding device is supported pivotably on the support frame. In this way, the holding means can advantageously be folded away when not in use so that they cannot be lost or stolen.

The holding device is installed in such a way that at least two layers of holding feet can be transported one above the other on the support frame underneath the barrier elements on the holding device. If the transport pallet can accommodate, for example, 20 barriers or separating elements, then 21 holding feet are required for this storage. According to the size and weight of the holding feet, they should be stacked compulsorily on the bottom of the pallet. To this end, a sufficiently high free space is required below the barrier or separating element. This is advantageously achieved by keeping the device at a greater height.

The holding device has stops on its sides, by means of which the holding device is supported on a barrier or separating element which can be placed next to the holding device. In other words, the holding device is secured in the tilted-up position by the barrier or the separating element. In practice, the barrier or spacer element on the edge side is first inserted into the pocket. As a result, the holding device is in an upright position in which it is secured by the barrier or the separating element and cannot be swiveled back. Next, a further barrier or spacer element is slipped onto the holding device. Advance together, transfer pallet loading and holding feet. Finally, on the other longitudinal side, a last barrier or spacer element is inserted into a pocket arranged laterally on the longitudinal beam, so that the retaining foot is reliably prevented from slipping off the bottom of the pallet. The pallet bottom must of course also have a backrest in the area of the holding device in order to prevent that the holding feet placed on the conveying pallet can slide off the conveying pallet on the end side. This backing device is thus supplementary to the side walls of the longitudinal sides, which are formed by bars or spacer elements inserted into the pockets. Suitably, the backrest device is an angle steel or a flat steel welded on the transverse beam.

In particular, the base of the pallet is not designed as a closed surface, but rather is designed as open, to some extent as a grid. It preferably consists of transverse braces parallel to the transverse beams and thus perpendicular to the longitudinal beams, which are arranged at a distance which is dimensionally secure against falling of the holding feet. The spacing between the individual transverse beams is dimensioned such that each holding foot always rests on at least two (preferably three) transverse beams. Overall, the supporting frame obtains a ladder-like structure by means of transverse beams, wherein the transverse beams or transverse braces form the grids. The transverse stays or grids are preferably made of T-shaped steel or angle steel, which are especially flush with the longitudinal beams with respect to their upper edges, so that a planar pallet bottom is produced without height deviations between the longitudinal beams and the transverse stays . The goal is to enable loading and unloading of the holding foot as unhindered as possible, ie to avoid upwardly raised edges as much as possible.

Optionally, intermediate struts are provided which are pivotably mounted on the longitudinal beams or which can be plugged on. This intermediate support serves to support the shorter spacer elements, which do not extend over the entire length of the conveyor pallet, whose ends are only fastened to a holding device. These spacer elements are fixed in a horizontal position by means of intermediate struts. It is expedient if the central strut is equipped with at least one locking element by which the central strut is held in the vertical position.

The spacer elements are generally considerably shorter than the barrier elements, so that in an overall shorter pallet the holding feet also have to be stacked on top of each other in at least two layers. Here, in some cases, insufficient construction space is not available for the central strut. Therefore, provision is made in an advantageous refinement for the holding device to be provided with a swing-down arm which can form an additional support surface for the pipe ends of the separating element. This cantilever, which can be folded down, is folded down towards the middle of the conveyor pallet, so that even shorter spacer elements (which are fastened in a plug-in fashion at one end) can be supported with the other tube end on the support surface . Since the spacer elements are fixed alternately in a plug-in manner, such a cantilever, which can be folded down in the middle, is required on every holding device. The tilting down of the boom is important because the holding device is swiveled for transport, ie likewise tilted down towards the center. In order that the cantilever does not get in the way when the holding device is swung down, the cantilever can be turned up for the transfer, so that they are arranged to a certain extent flush with the holding device and thus lie entirely flat on the bottom of the pallet during the transfer .

In a development according to the invention, the pocket is provided with an upwardly directed spacer element, against which the lower edge of the inserted barrier or spacer element rests. In this connection it is advantageous if the lower edge is located approximately in the middle third of the height of the holding foot. The distance from the lower edge to the upper side of the base of the pallet preferably corresponds to half the height of the holding foot. This spacer element also has the function that the lower end of the tube element cannot protrude too far downwards beyond the bag. The conveyor pallet as a whole preferably has a relatively low construction height, so that the pockets also preferably have a height that is not greater than the height of the longitudinal beams, in particular corresponds to the height of the longitudinal beams. The pocket is preferably a cut-to-length rectangular profile tube which is welded to the longitudinal beams on the longitudinal sides and which is open above and below at its insertion opening.

Another advantage of the laterally arranged pockets is that the barrier or spacer element is now inserted with two pipe ends and is not only fixed on one side to the holding device, so it can neither be on one end nor on the Slide the other end up and down. The insertion depth is greater than the area of the holding device, which ultimately results in greater safety, since it is also ensured that barriers or separating elements on the edge sides do not dislodge slipping off in the parts and because this also ensures that the holding feet remain on the conveyor pallet. If the transfer frame is twisted under unsuitable stresses, the tube ends can even get stuck in the pockets, making it impossible to jump out.

Detailed ways

FIG. 1 shows a conveyor device with a conveyor pallet 1 on which barrier elements 2 are plugged and fastened. In addition, holding feet 3 , 4 also belong to the conveyor, which are located one above the other on the pallet bottom 5 of the conveyor pallet.

An important component of the invention is the transfer pallet 1 . As shown in FIGS. 2 to 4, the conveyor pallet comprises a horizontal, rectangular support frame with longitudinal beams 7, 7a extending parallel to each other, which pass through outer transverse beams 8, 8a and inner The transverse beams 9, 9a are connected to each other. Furthermore, a plurality of transverse braces 10 extend parallel to the transverse beams 8 , 8 a and thus perpendicularly to the longitudinal beams 7 , 7 a. Together with the longitudinal beams 7 , 7 a , which are rectangular in cross section, and the outer transverse beams 8 , 8 a , these transverse braces 10 form a pallet base 5 on which the holding feet 3 , 4 can be placed.

Another important component of the transfer pallet 1 is the holding device 11 , which is pivotable about the axis A towards the middle of the support frame 6 . Such holding means 11 are located on each end of the transfer pallet 1 . In FIG. 2 , the holding device 11 is in an upright position in which it is ready to receive the barrier element 2 in a plug-in manner. For transport, this holding device 11 is turned downwards, so that a lower construction height is achieved during transport.

The loaded or unloaded transfer pallets 1 can be transferred by means of handling forks. The handling fork can be inserted in the transverse direction into the inner transverse beam 9 , 9 a and in the longitudinal direction into the longitudinal beam 7 , 7 a. Both the transverse beams 9 , 9 a and the longitudinal beams 7 , 7 a are rectangular. The transverse beams 9, 9a are located below the longitudinal beams 7, 7a. The transfer pallet 1 is supported on transverse beams 9, 9a. Furthermore, support legs 12 are provided on the corners of the transport pallet 1 , by means of which the transport pallet 1 is likewise supported on the ground. Transverse beams 8, 8a as well as support legs 12 give the transfer pallet a ground clearance which makes it possible to lift the machine by hand Realize teleportation. For this purpose, this ground clearance is 10 cm.

In the case of the conveyor pallet 1 according to the invention it is essential that recesses 13 are provided on the sides of the longitudinal beams 7 , 7 a , into which recesses 13 can be inserted from the edge sides, respectively, of the barrier or separating elements 2 . The barrier or locking elements 2 each have vertically extending standpipes 14 at their ends, which are inserted into the holding feet 3 , 4 when erecting the barrier or partition. The pipe ends 15 thus protrude beyond the lower edge 16 extending between the standpipes 14 . Therefore, the lower edge 16 of the barrier element is always lower than the upper edge of the associated holding foot 3 .

As shown in FIG. 1 , the height of the lower edge 16 lies approximately in the middle of the lower holding foot 3 , so that the holding foot 3 cannot slip off the transport pallet 1 on the longitudinal side. Further barrier elements, not shown in detail, can be fastened by plugging on the holding device 11 . To this end, the holding device 11 is mounted at a height such that a corresponding number of holding feet 3 , 4 can be carried, which corresponds to the number of barrier elements 2 . To be precise, one additional holding foot 3 , 4 has to be carried compared to the barrier element 2 arranged on the transport pallet 1 .

Dot-dash lines are marked in FIG. 1 and are intended to indicate the lower edges 17 of those barrier elements that are plugged onto the holding device 11 . It can be seen that in this embodiment two layers of holding feet 3 , 4 are conveyed one above the other, wherein the upper layer of holding feet 4 fits conveniently under the barrier element 2 arranged in the middle of the conveying pallet 1 .

As is apparent from FIG. 4 , the pockets 13 arranged on the corner and longitudinal sides of the longitudinal beam 7 are each equipped with upwardly facing spacing elements 18 . This spacer element 18 is arranged on the sides of the pocket 13 facing each other, so that the lower edge 16 of the barrier element 2 inserted in the pocket 13 can bear on the upper edge of the spacer element 18 . This prevents the lower edge 16 from abutting against the upper edge of the pocket 13 . Because the pocket 13 does not protrude upwards beyond the level of the pallet bottom 5, the barrier element 2, without spacer elements, could slide too far into the pocket 13 so that its tube end 15 is drawn from below. The open pocket 13 sticks out too far. It is therefore expedient for the lower edge 16 to lie approximately in the region of the middle height of the lower layer of the holding foot 3 . This spacer element 18 thus has a length which is 40% to 60% of the height of the holding foot 3 to be carried.

The pocket 13 is a hollow profile with a rectangular cross-section, which enables a limited movement of the inserted barrier element 2 in the longitudinal direction.

It can be seen from FIG. 3 that the inner transverse beam 9 , 9 a protrudes outside the longitudinal beam 7 , 7 a so far that it is aligned with the pocket 13 . This ensures that the grating or insulating element 2 fastened in the bag 13 is not damaged by the deep penetration of the loading and unloading fork into the transverse beam. Thus, the length of the inner transverse beams 9 , 9 a determines the width of the transport pallet 1 . The outer transverse beams 8 , 8 a extend beyond the outer longitudinal sides of the longitudinal beams 7 , 7 a as far as the pocket 13 . In contrast to the inner transverse beams 9, 9a or longitudinal beams 7, 7a, the outer transverse beams 8, 8a are not designed as hollow profiles, since the loading and unloading forks should only be inserted into the inner transverse beams 9, 9a or longitudinal beams 7, 7, 7a. For this purpose, the longitudinal beams 7 , 7 a or the inner transverse beams 9 , 9 a are designed as rectangular tubes, which together reinforce each other.

The fence element 2 is of course also used at the same time to secure the holding device 11 in the upright position. This is explained most directly with the aid of FIGS. 5 to 7 . The holding device 11 shown comprises a horizontally extending transverse beam (Traverse) 19 made of angle steel. Pipe pieces 20 are arranged at regular intervals on the upper side of this cross member 19 to receive the pipe ends 15 of the grating or insulating element 2 in a plug-in manner. Arranged below this horizontally extending crossbeam 19 are two vertically extending struts 21 which likewise consist of angle steel. The edge of this strut 21 oriented parallel to the longitudinal beams 7, 7a is provided with an aperture at its lower end, into which a bolt can be introduced in order to connect the strut 21 (and therefore the holding device 11) pivotably to the supporting frame. 6 connected. For this purpose, there is a clamp 22 on the support frame 11 , which clamp 22 can be connected to the strut 21 . The lower end of the strut 21 is rounded towards one side, so that the holding element 11 can only be folded towards the inside, ie towards the middle of the transfer pallet 1 . The holding device 11 can be fixed in its vertical position by the stop 23 protruding at the end of the cross member 19 abutting against the standpipe 14 of the grating or insulating element 2 fastened in the pocket 13 .

The barrier elements 2 are inserted alternately on the holding device 11 , so that one pipe end 15 of the barrier element 2 engages in each case with a pipe piece 20 , while the other pipe end 15 is situated on the upper side of the transverse beam 19 . Length tolerances between the individual barrier elements are thus better compensated than with plug-in fastening on both sides. In order to prevent the barrier elements 2 arranged on the outside of the holding device 1 from sliding off, a protective element 24 in the form of an upwardly directed sheet is provided at each end of the transverse beam 19 .

8 and 9 show holding devices 11 to which a cantilever 25 has been added, respectively. In FIG. 8 it can be seen that the boom 25 is in its upwardly folded state. In FIG. 9 it can be seen that the boom 25 is in its folded-down position. This cantilever 25 is used to a certain extent to enlarge the bearing surface for the pipe end 15 in the area of the transverse beam 19 . In the folded-down position according to FIG. 9 , this cantilever 25 is situated at the same height as the support surface of the crossbeam 19 , thus increasing the width of the crossbeam 19 to a certain extent. It can be seen with reference to FIG. 8 that the boom 25 does not protrude beyond the longitudinal sides of the crossbeam 19 in the tilted-up position, so that the pivotable holding device 11 can also be pivoted together with the boom 25 to lie flat on the pallet base 5 .
