Description

The invention relates to a securing element for fixing an end wall on a trans port document, with the help of the front wall one wrapped with a sheet-like material Sleeve in a horizontal orientation of its longitudinal axis about this is rotatably supported and wherein the securing element has at least one breakthrough for carrying out a Has transport pad anchorable fastener, and in a fixing position the end wall against movements of a horizontal plane relative to the transport pad guaranteed.

It is known to use sheet-like material on sleeves made of plastic or paper, for example in Form of foils to wind up. Such z. B. plastic films are for different uses, for example in the electronics industry, ver turns and are due to their very low strength and high quality requirements to be handled with great care during processing. After winding up such Films on the sleeve at the manufacturer are often initially with the rolls thus formed so-called end plates made of a cushioning material such. B. provided with a foam, to protect the sensitive end faces of the film wound into a roll. On Both ends of the film roll formed on the sleeve is then made of a plastic Material existing, usually square, front wall limited, the edge length is larger than the diameter of the film roll. From the end wall there is a center on one side arranged pivot vertically in front, which can be inserted into the bore of the sleeve. The Both end walls therefore support the film roll on both sides and allow one on the one hand gentle transport and on the other hand safe storage of the package formed.

The storage and transport unit formed from a film roll and two end walls is on one or with the appropriate length of the sleeve, on several transport documents in usually placed in the form of wooden or plastic pallets, with the help of conventional transport and lifting devices, for example forklifts or pallet trucks To enable lifting and transporting the film roll. To the film roll and two Frontal unit formed during transport - for example, with the help of load motor vehicles or the railroad takes place - as well as to stabilize the storage Unit usually strapped with straps. According to the arrangement of the unit on one or  Several pallets are usually strapped again with the help of additional clamps tapes made, which also encompass parts of the range and thus should prevent that the unit consisting of film roll and end walls during transport on the or hike the pallets and in the worst case even slide off them can.

However, since the length of the sleeve often does not coincide with the length of one or more arranged pallets matches, it often happens that during transport a relative despite the common strapping of the film roll, end walls and pallet (s) movement, especially between the end walls and the pallet (s), cannot be prevented, so that in the event of an end wall slipping, damage to the film roll can occur.

A T-shaped fuse designed as a plastic injection molded part is generally known element with a protruding nose in an adapted recess at the bottom engages an end wall. The securing element is fastened with screws so that it on the one hand abuts the front wall and therefore a movement of the same in a horizontal Prevents direction perpendicular to the end wall plane and on the other hand with the help the protruding nose manufactured a movement of the end wall also in hori zontal direction parallel to the front wall plane prevented. While the front wall is in horizontal direction is completely fixed, the fixation in the vertical direction by Spann tapes taken on the bottom of the pallet and the top of the film roll run.

A disadvantage of the known securing element is the fact that the forehead wall with a recess on its underside for engagement through the nose of the siche must be provided. Such recesses are standard for many used end walls, which are reusable components, unavailable. Subsequent incorporation of such recesses is complex and therefore not practical in practice. Furthermore, security is despite the tensioning straps which and despite notches formed on the underside of the partition walls, jagged notch elements, that should dig into the surface of the pallet are not sufficiently safe.  

From US 6,098,974 is a transport pad for an armature of an electric motor known. Such documents should be used during the manufacturing process of the anchor the one with two end sections of its shaft on partition-like support elements. Simple and permanent around a clear angular position of the anchor ensure an eccentrically arranged end portion of the shaft engages in a vertical slidably arranged on the actual support element second support element. Simply because of the effect of gravity, this is an un desired rotation of the armature prevented during the manufacturing process. The problem is a vertical displacement of the armature caused, for example, by vibrations not solved by the previously known device.

The invention has for its object to propose a securing element that none lei recesses on the end walls required and for a secure fixation of the end wall on a transport document, even if adverse transport conditions, for example with great shocks or vibrations.

Starting from a securing element of the type described above, this task solved according to the invention in that the securing element in the fixing position with a Contact surface on an essentially horizontal fixing surface of the end wall is supported.

The securing element according to the invention makes use of the fact that the existing end walls are usually horizontal fixing surfaces, which are suitable for being brought into contact with a contact surface of the securing element in order to prevent the front wall from moving in the vertical direction. The horizontally running fixation surface is available in particular from existing end walls Edging strips running perpendicular to the end wall plane, from which reinforcing ribs of the front wall which intersect at right angles.

With the help of the end wall fixation according to the invention, strapping can be carried out entirely means of such straps can be dispensed, both from the film roll and end walls formed unit as well as the transport document (s) simultaneously. The tension band  However, the strapping of the unit formed from the end walls and the film roll should be retained to ensure the stability of this unit both during transport and during a ensure later storage after removal from the transport pad. By the waiver of strapping including the transport document (s) can be a not inconsiderable savings in material and labor, because the fiction moderate securing elements quickly and easily on the one hand - e.g. B. by means of screws and elec trically driven screwing tools - can be assembled and disassembled and more advantageous Way reusable.  

According to a preferred embodiment of the securing element, the contact surface has a height offset to a parallel to this aligned base, which in the Fi xierposition of the securing element is in contact with the transport pad.

Furthermore, it is proposed that the contact surface be arranged on a cantilever part protrudes over a base body of the securing element, the cantilever part with a Slot is provided, which in the fixing position of the securing element with a rib Front wall can be brought into engagement. The fixation against slipping sideways by Integra tion of a rib in the securing element allows only a single securing element use per end wall and still fix the end walls - in combination nation with a similarly designed securing element on the opposite Front wall - against movement in all directions.

If the slot extends through the cantilever part into the base body, forces running in the direction of the rib plane or the longitudinal direction of the slot are not from the rib end, but a contact surface on the base body.

To avoid damage to the rib end, it is also possible to use the slot round off in a top view at its end.

The invention is further developed, that the cantilever part in a perpendicular to the Center plane of the slot and cutting plane aligned perpendicular to the contact surface is roof-shaped.

In order to achieve essentially constant wall thicknesses of the To achieve cantilevered part and thus an uneven cooling behavior in an injection molding To prevent technical manufacture of the cantilever, it is proposed that the cantilever on both sides of the slot over its entire length with one opposite the contact surface recessed recess is provided.

Finally, it is to facilitate the attachment as well as the removal of the securing element particularly useful from the transport document, the central axis of the breakthroughs for the  Fasteners to incline away from the slot relative to the plane of the base. In particular screwing tools, such as cordless screwdrivers or the like, can be used in such a Use the slope of the breakthroughs particularly advantageously and use it to secure the fuse fasten the element using screws.

The invention is described below using an exemplary embodiment of a securing element ment, which is shown in the drawing, explained in more detail. It shows:

Fig. 1 Two on a pallet arranged end walls and two securing elements for its fixation;

Fig. 2 is a front view of a securing element;

FIG. 3 shows a side view of the securing element according to FIG. 2;

FIG. 4 shows a plan view of the securing element according to FIG. 2;

Fig. 5 is a section through an end wall with the dargestell th in FIGS. 2 to 4 locking element in a fixing position, and

Fig. 6 is a rear view of the securing element of FIG. 5.

Figs. 1 shows a transport support in the form of a pallet 1, in parallel on the two and mutually spaced end walls 2 situated. The end walls each have a vertically projecting receptacle 3 inserted therein, which can be guided in a bore of a sleeve, not shown, for receiving a web-shaped material. The two end walls 2 , together with the receiving pins 3 , therefore take on the function of supporting and protecting the end of a film roll located on the supported sleeve. The film roll has a diameter that is always smaller than the edge length of the end walls 2 .

The end walls 2 are designed as plastic injection molded parts and are provided on the side facing away from the film roll with mutually perpendicular horizontal ribs 4 and verti len ribs 5 . The end walls 2 are each provided with a circumferential, self-contained edge strip 6 at the end of the ribs 4 and 5 .

Both end walls 2 are fixed to the pallet 1 in the lower, horizontal section of the edge strip 6 with the aid of two securing elements 7 . The structure of the hedging element 7 is discussed in detail below:
From FIGS. 2 to 3 it can be seen that a securing element 7 consists of a bar-shaped base body 8 and a cantilever part 9 extending therefrom. The cantilever part 9 has two contact surfaces 10 which are separated from one another by a slot 11 . Between a base surface 12 of the base body 8 and the contact surface 9 there is a height offset 13 which corresponds to the wall thickness of the edge strip 6 of the end wall 2 .

As can be seen in particular from FIG. 2, the cantilever part 9 is formed roof-shaped, in particular in its end section facing away from the base body 8, symmetrically to a central plane 14 of the slot 11 . Since the cantilever part 9 is further provided on both sides of the slot 11 with a recess 15 that recesses relative to the contact surface 10 , the cantilever part 9 has essentially constant wall thicknesses in its front section, which begins the cooling behavior of the securing element 7 produced as an injection molded part.

The base body 9 is provided with two openings 16 formed as through bores, the central axes 17 of which - as can be seen in particular from FIG. 3 - with respect to a surface normal 18 starting from the plane of the base surface 12 by the angle α of approximately 15 ° C. from the slot 11 are inclined away.

As can also be seen in FIG. 3, the side surface 19 of the cantilever part 9 , like the side surface 20 of the base body 8, has a trapezoidal shape.

FIGS. 5 and 6 show the fastening element 7 in its fixing position in which it at a horizontally extending fixing surface 21 of the edge strip 6 of the front wall 2 rests with its bearing surface 10 on the cantilever member. 9 With a vertically oriented further contact surface 22 , the securing element 7 is in contact with an end face 23 of the edge strip 6 . In addition, a vertical rib 5 of the end wall 2 engages in the slot 11 in the cantilever part 9, which ends with a rounding 24 . Since both opposite end faces 2 are each fixed with at least one securing element 7 , a unit consisting of two end faces 2 and a film roll arranged between them is secured against movements in all directions. The securing elements 7 are fastened with the aid of countersunk screws, not shown, which are screwed into the pallet 1 .

From Fig. 6 it can finally be seen that the horizontal section of the edge strip 6 of the end wall 2 is provided on its underside 25 with teeth 26 which are to dig into the wood of the pallet 1 and therefore relieve the pressure on the Si securing elements 7 cause vibrations during transport.
