Description

The invention relates to a stanchion frame which is intended for loading with piece goods, in particular with cylindrical goods. The invention further relates to a transport system.

A possible design of a stanchion frame is in the DE 1 872 386 U described. The well-known stanchion frame should be usable in particular for transporting bulky parts in the motor vehicle industry. A floor, which supports the stanchions, is formed from the longitudinal and transverse bars of the stanchion frame. In the case of the stanchion frame after the DE 1 872 386 U spar pairs are designed as runners to move the entire frame on a runway can.

The EP 2 888 174 B1 describes a pallet for goods to be transported, which comprises a pallet body which is formed on the foot side from a tubular frame whose frame parts are telescopic. At the bottom of the pallet there are fixing means for the goods to be transported, which include a V-shaped adjustable shelf for fixing different diameters of the goods to be transported. Legs of the V-shaped shelf are supported from the floor by adjustably mounted braces. The goods to be transported can be a roll or a coil.

Another transport frame, which is intended, among other things, for loading goods that have a cylindrical basic shape, is in DE 10 2016 103 509 A1 described. In this case, too, a shelf has a V-shaped basic shape.

The DE 1 260 261 B discloses a cable reel with an electric drive that is attached to a mobile device and is used for spirally winding up electric lines or cables. The mobile device can be a crane, for example. A gearbox is connected between the cable drum and the drive motor.

For example, various vehicle trailers that can carry cable reels are in the documents CH 308169 A and DE 31 39 141 A1 disclosed.

The DE 298 15 431 U1 discloses a cable and wire unwinding and transporting apparatus having a base frame constructed of square steel tubing. Wheels on the base frame should ensure mobility in all construction areas.

The DE 295 21 477 U1 describes a receiving device for a cable drum, with the cable drum being in a defined position on the receiving device. The receiving device is designed as a pallet on which the cable drum rests in a rotationally fixed manner with the axis of rotation aligned horizontally.

The invention is based on the object of specifying further developed options for transporting and storing cylindrical goods such as coils compared to the stated prior art, with applicability being given in particular in cases in which the cylindrical good cannot be gripped in the area of its central axis.

This object is achieved according to the invention by a stanchion with the features of claim 1. The stanchion provided for loading with cylindrical goods has a base frame on which stanchions are arranged in two rows, each row comprising more than two stanchions and each row Stanchions is penetrated by a crossbar, which corresponds to a line support for a plurality of cylindrical goods that can be supported directly or indirectly on two stanchions in the axial direction of the goods and thus also the crossbars.

The cylindrical goods, for which the stanchion frame is designed to hold and transport, are coils, for example, which are used for the production of electrotechnical devices. Irrespective of the type of cylindrical goods, in numerous embodiments they have a flat disc shape, with the central axes of the individual cylindrical goods to be accommodated by the stanchion frame always being aligned parallel to the two crossbars. The distance between the transverse bars is, for example, 70% to 90%, in particular approximately 80%, of the diameter of the cylindrical goods.

In all cases, the crossbars have multiple functions: on the one hand, they hold the stanchions together or at least stabilize them. On the other hand, they serve to support the cylindrical goods in the stanchion frame. As far as the cross-sectional shape of the horizontally aligned crossbars is concerned, there are numerous design options. In the simplest case, the crossbars have a circular cross-section. Likewise, transverse rods with a trapezoidal or triangular cross-section can be used, in which case a surface of the transverse rod that contacts the cylindrical product describes a tangent to the product. Furthermore, there is the possibility of convexly forming surface sections of the crossbars, so that the contact surfaces between the goods to be transported and the crossbars are even larger are. In none of the cases mentioned does the material accommodated in the stanchion frame lie on a floor of the stanchion frame. A rotation of the cylindrical material placed on the stanchion frame about its own axis, for example in order to wind or unwind a spool, is not provided for in typical applications, but is not ruled out in principle.

The number of stanchions within a row can be, for example, three, four, eight, ten or more. The stanchions can be arranged equidistantly. Likewise, embodiments can be realized in which there are different distances between stanchions arranged next to one another, which means that the stanchion frame is designed for the simultaneous accommodation of cylindrical goods of different widths. In a manner known per se, the stanchions are aligned vertically. An adjustability of the distances between the stanchions can also be provided.

The distance between two stanchions, which are located in a row of stanchions, can be adjusted in various ways to the dimensions of the objects to be transported. For example, the distance between two stanchions is slightly larger than the thickness of the disc-shaped objects, so that exactly one such object can be placed between two stanchions. Configurations are also possible in which the distance between the stanchions corresponds to a multiple, for example twice or three times, the thickness of the disc-shaped objects to be transported, e.g. coils, so that two, three or more similar objects are placed between two stanchions can.

According to an advantageous embodiment, all the stanchions are designed as strip-shaped elements which are arranged parallel to one another in a plane to which the crossbar connecting the stanchions represents a surface normal. This applies equally to both rows of stanchions. Due to the strip shape of the stanchions, compared to the space occupied by the stanchions, a relatively large amount of space is available for accommodating the cylindrical, in particular disc-shaped, goods.

The thickness of each stanchion to be measured in the direction of the crossbar, ie in the axial direction of the cylindrical goods, is, for example, less than half the width of the stanchion. In the case of extreme thickness/width ratios of the stanchions, these are positioned between the disc-shaped goods to be transported in the form of slender blades, almost like vertically positioned swords. Conceivable forces which could act in the sense of a tipping of the goods in an upright position are absorbed by a plurality of stanchions which are arranged in a comb-like manner in each row, in particular in cases in which the goods contact both adjacent stanchions. It is also possible to accommodate each individual cylindrical part to be transported or several such parts between a total of four stanchions, ie two stanchions in the first row and two stanchions in the second row, with play. In such cases, too, the weight of the cylindrical, in particular disc-shaped, parts is carried entirely by the two crossbars of the stanchion frame, also referred to as connecting struts. The thickness of each stanchion, regardless of the type of goods to be supported, can be, for example, less than a third of the distance between two stanchions.

The two rows of stanchions parallel to one another are each aligned in the transverse direction of the rectangular, non-square base frame in numerous possible configurations of the stanchion frame. The size of the base frame depends on the requirements of the individual case and can, for example, correspond to the dimensions of a Euro pallet (1,200 mm x 800 mm). In such a case, cylindrical parts, such as coils, can be placed on the pillar frame, the diameter of which utilizes the length of the base frame (1,200 mm) as much as possible. On its underside, the base frame is designed, for example, in the manner of a four-way pallet.

The stanchion frame can be part of a transport vehicle or can itself be designed as a transport vehicle by means of wheels attached to the base frame. In typical configurations, the wheels are not driven. Deviating from this, a wheel drive can be advantageous, especially in cases where heavy goods are to be transported. Irrespective of the presence of a drive, in particular an electric drive, of the trolley including the stanchion frame, there can be at least one attachment contour for a lifting device, in particular a forklift, on the base frame or on a separate chassis.

According to various possible, particularly robust designs, the two rows of stanchions are arranged between four comparatively high corner supports that protrude beyond the stanchions. The corner supports can be designed to form a stack of several similar stanchion frames, with four feet of the frame being formed by the corner supports at the same time.

To increase the mechanical load capacity, the two outermost stanchions of each row of stanchions can each have a corner support to be connected. For this purpose, in particular, connecting strips can be provided which each connect a stanchion, in particular at its upper end, to one of the corner supports.

According to the invention, the stanchion frame together with a three-point gripper forms a transport system whose components are coordinated with one another and with the goods to be handled. One advantage of a three-point gripper is that the cylindrical goods can only be gripped on their outer circumference. This means that goods can also be lifted and set down that do not have an opening in the area of their central axis. The three-point gripper has three gripper arms parallel to one another, two of these arms being able to be positioned under the cylindrical product and the third gripper arm, which in particular prevents the lifted product from tilting, can be placed centrally on top of the cylindrical product.

The two lower gripper arms are offset from one another, for example by 90°±10° on the circumference of the cylindrical material, in particular the coil, while an angle of 135°±10° is enclosed between each of the lower gripper arms and the upper gripper arm. The lower gripper arms can move into the free space between the stanchions, the cylindrical product and the base frame and lift the product in such a way that it is in balance. As far as the cross-sectional design of the gripper arms is concerned, the comments on the cross-sectional design of the crossbars of the stanchion frame apply analogously. In particular, the gripper arms can each have a circular cross section. Since the two rows of stanchions are only connected to one another via the base frame, optionally also via additional elements which are located outside the free space formed between the stanchions, there are no elements that could prevent the gripper arms from attacking the cylindrical parts.

The three-point gripper can be designed in such a way that either only a single part or a group of parts can be raised or lowered with it. In all cases, compartments are formed by the stanchions of the frame and by the crossbars, which are each provided either for receiving exactly one cylindrical part or for receiving several identical or different parts of the same diameter. With the help of the three-point gripper, it is possible to load cylindrical, in particular disk-shaped, objects onto the stanchion frame and unload them from it without actuating any movable safety elements, such as bolts or levers, on the stanchion frame.

Several exemplary embodiments of the invention are explained in more detail below with reference to a drawing. Show in it:

Unless otherwise stated, the following explanations relate to all exemplary embodiments. Parts that correspond to one another or have the same effect in principle are identified by the same reference symbols in all figures.

A transport system identified overall by the reference number 1 comprises a stanchion frame 3 and optionally a transport carriage 2 ( 1 until 3 ). In any case, the stanchion frame 3 is designed to accommodate a plurality of coils 12, which are generally referred to as cylindrical goods. In the embodiment according to 1 until 3 there are ten coils 12 on the trolley 2. The same applies to the stanchion frame 3 after the 4 and 5 . The 6 and 7 illustrate the possible accommodation of nine coils 12 (three times three) on the stanchion frame 3. In all cases, the stanchion frame 3 is compatible with a Euro pallet in terms of its dimensions (1,200 mm x 800 mm).

The uniform diameter of the coils 12, which, for example, each have a mass of up to 16 kg and can also be heavier in individual cases, is denoted by D12. All coils 12 are supported by a single stanchion frame 3, which can be combined with the trolley 2. In addition to the stanchion frame 3 and the optional transport trolley 2, the transport system 1 is only equipped with an 1 The three-point gripper 4 shown to some extent, but which can also be used in all other cases, whose three gripper arms are denoted by 5.

With the help of the gripper arms 5, which how out 1 shows, each have a circular cross-section, the coils 12 can be used individually or in groups at the periphery who the. Gripping in the area of the central axis of the coils 12 is not provided. How further from 1 shows, the three-point gripper 4 is configured so that its two lower gripper arms 5 engage in the free space between the two rows of stanchions, which are designated 13, 14. The clear width between the rows of stanchions 13, 14 is denoted by BL. At the same time, the upper gripper arm 5 can be placed centrally on the coils 12.

The coils 12 removed from the stanchion frame 3 are fed, for example, to a production plant that is not shown. When handling the cylindrical goods 12 by means of the transport system 1, it is not necessary to actuate any safety devices, for example to block parts.

The stanchion frame 3 is formed from a base frame 6 and a structure denoted overall by 8 . If a trolley 2 is present, its partially steerable wheels are denoted by 7 . Furthermore, in this case, a drawbar 11 and - at the rear end of the trolley 2 - a vertical element 15 is present. The length of the trolley 2 is denoted by LW, the width of which is denoted by BW. The length and width specifications LW, BW refer to the versions without transport trolley ( 4 until 7 ) to the dimensions of the base frame 6. HR denotes the height of the stanchions 9, H _total the total height of the stanchion frame 3.

An attack contour 16 for a lifting device, not shown, has a so-called handling width HW. This makes it possible, for example, to lift the entire transport carriage 2 including the coils 12 using a conventional forklift. If the attack contour 16 is located directly on the base frame 16 ( 7 ), it can be given in the form of several forklift shoes 20.

The structure 8 comprises a large number of stanchions 9 and exactly two crossbars 10, which are also referred to as connecting struts. Here, each crossbar 10 penetrates a row 13, 14 of stanchions 9 1 shows, from the base frame 6 are lifted. In this way, a generously dimensioned space for attacking the two lower gripper arms 5 of the three-point gripper 4 is made available.

For the means of the three-point gripper 4 can be charged onto the stanchion frame 3 and can be lifted off the coils 12, as can be seen from the 1 until 5 shows that a separate compartment is available, which is limited by a pair of stanchions 9 in the first row 13 and a pair of stanchions 9 in the second row 14 . According to 6 and 7 on the other hand, three coils 12 can be used in each compartment, each of which has a width BG. The crossbars 10, which run through all compartments, always represent line supports for the goods 12 to be transported.

The stanchions 9 are strip-shaped elements with a thickness DR and a width BR. The distance between two adjacent stanchions 9, designated AR, specifies the usable space for one coil 12 or for a group of coils 12. The stanchions 9 support the coils 12 in their axial direction, ie in the transverse direction of the stanchion frame 3 . In the exemplary embodiments, the height HR of each stanchion 9 is more than half the coil diameter D12.

The 4 until 7 show a possibility, the tilting rigidity of the stanchions 9 compared to the design after 1 until 3 to increase. There are four corner supports 17 that protrude beyond both the stanchions 9 and the coils 12 and also ensure that the stanchion frame 3 can be stacked. The two outer stanchions 9 of each row 13, 14 are each connected to one of the corner supports 17 via a connecting strip 18. Cross-connecting strips 19, which are at the level of the upper end of the stanchions 9 and thus at the same time at the level of the connecting strips 18, each connect two corner supports 17 without being directly connected to any stanchions 9. Furthermore, the base frame 6 attributable ground struts 21 are present, on which all stanchions 9 with the exception of the two outer stanchions 9 of each row 13, 14 are supported.
