Description

Field of application of the invention

The invention relates to a barrel made of thermoplastic material with a from the barrel shroud in the vicinity of the barrel bottom in the axial extension of the cylindrical shell part projecting rolling ring «in which the subsequent from the groove bottom between rolling ring and barrel sheath jacket region merges into the barrel bottom ·

Characteristic of the known state of the art

Usually barrels are equipped with the end shells in close proximity associated end faces «solid in cross-section carrying and transport rings with a horizontal and a vertical contact surface for the gripper arms of a used barrel gripper equipped«

Most of these barrels are barrels produced in their entirety by blow molding, in which the carrying and transport rings are integrally formed during production from the drum casing. However, barrels are also known in which the tubular drum casing part and the drum end regions are separate from one another · The end regions produced in the spray-molding process with the carrying and transport rings attached thereto are welded on the tubular barrel trunk in a further operation *

Because the carrying and transport rings when obliquely hitting a filled cask that crashes at a certain height

Because of their comparatively small Manteletörke extremely vulnerable 3ind, the rings must be preceded by a so-called Knautechzone. This is done in such a way that the rings are arranged at a distance below the top or bottom edges of the barrel «The over the annular groove projecting barrel shell areas rise conically against the barrel axis on»

When obliquely or vertically impinging the falling barrel the lying above the rings elastic Faßendbereiche be deformed, eho the rings are achieved.

Because of the comparatively small distance of the rings from the barrel head or bottom, the operator can grasp the rings by hand when obliquely rolling the barrel, so that an extremely favorable "handling" results.

When obliquely rolling the filled barrel, the bottom edge pressed by dao barrel weight flat, so that a disturbing flexing work when rolling occurs. By supporting the respective carrying and transport ring against the ground, the bottom edge deformation is to be partially absorbed and thus the disturbing flexing work to be mitigated «

Nevertheless, rolling the barrel over the bottom edge is still severely hampered. In addition, the edge region in the transition of the drum casing in the drum bottom is comparatively thin and can be overstressed in rough operation, especially when oblique rolling by hand. Furthermore, the risk of accidents when tilting and rolling the barrel is increased by the upstanding rolling ring, under which the operator's foot can be squeezed in. «

Since in itself only the upper carrying and transporting ring forms the abutment for a used Faßgreifer with which the barrel is lifted and transported, offers the lower carrying and transport ring to be redesigned to a different function »It must also take into account that the deformation forces are trapped non-destructively when a filled barrel falls *

Object of the invention

The aim of the invention is to increase the utility value properties of drums of the generic type in a cost-effective manner.

Explanation of the essence of the invention

The object of the invention is to develop a barrel in which the lower carrying and transport ring is redesigned so that the deformation forces can be absorbed in the crash of a filled barrel «

According to the invention the object is achieved in that the rolling ring in cross-section has the approximate shape of a trapezoid whose narrowest point lies in the groove bottom of the ring and from there rises in the thickened end portion of the ring, and the axial end surface of the ring terminates in the plane of Faßbodens "

From this it can be seen that the lower crumple zone was taken back so that the barrel can only be rolled over the rolling ring «

The impact energy generated by the oblique or vertical impact of a falling barrel is absorbed directly in the rolling ring, which folds inwards around the narrow attachment point on the barrel casing and thereby deforms elastically until it impinges on the conical jacket part and is supported there * In this way the impact energy is consumed by the deforming rolling ring.

The vertical stacking forces are absorbed by the rolling ring and by the Faßbodan, with a distribution of forces on the cylindrical shell part in the ring and the conical Mantelt.eil into the Faßboden · The end face of Faßbodens can be set back slightly relative to the axial end face of the rolling ring to achieve a lush cushion on the floor

When rolling the edged barrel, this is slightly inclined. "According to the invention, the diagonal loading occurring when rolling over the edge can be better absorbed by the rolling ring starting slightly inclined outwards from the groove base, wherein the extension of the central axis through the annular cross section is the center of gravity cuts inside the barrel. As a result, the rolling ring is largely relieved of bending forces during unrolling, so that due to the only slight deformation a comparatively narrow limited ground support is achieved, which favors the Abrollvo ^ gang The stacking forces are introduced directly through the rolling ring in the barrel shell.

If in an embodiment of the invention, the outer diameter of the radial end surface of the rolling ring corresponds to the circumferential diameter of the drum casing, is a lossless palletizing

of the barrel.

It is also according to the invention that the rolling ring is stiffened in its narrowest cross section in the inner and outer peripheral areas by evenly distributed axial ribs «

Embodiment ·

The solution according to the invention will be explained in more detail below in an exemplary embodiment with reference to the accompanying drawings.

Show it:

It is a bung barrel in side view;

Fig. 2: an enlarged section of the head side of the barrel and

3 shows an enlarged detail of the bottom side of the barrel.

In the drawing, the cylindrical part of the drum casing 4 of the barrel 9 "the head end face IO and the end face of the barrel bottom 7 are shown" in the barrel head are not shown Spunde «

In the vicinity of the barrel head is the cross-section massive carrying and transport ring 11 with a horizontal contact surface 13 and a vertical contact surface 14 for not shown in the drawing gripper arms of a Faßgreifers used «

The carrying and transporting ring 11 is integrally connected to the barrel shroud 4 via the connecting ring 15, which adjoins the horizontal contact surface 13. The groove base between the connecting ring 15 and the shell part 12 rising conically against the top end surface IO is in the exemplary embodiment at a distance below the horizontal Anlagefloche 13 of the carrying and transport ring 11 arranged »

The rolling ring 1 on Faßbodenbereich has approximately the shape of a trapezoid in cross-section * The narrowest or narrowest point of the rolling ring 1 is in the groove bottom 2 # In addition to the better weldability of the compressed material during production here is a kind of hinge created to the ring 1 at from the narrowest point the ring 1 rises into the thickened end area ·

The axial Enfläche 5 of the ring 1 terminates approximately in the plane of the Faßbodens 7, which merges via the conical casing part 6 in the cylindrical drum casing 4. The radial end surface 3 corresponds to the circumferential diameter of the drum casing 4 «

Starting from the groove base 2, the rolling ring 1 is inclined slightly conically outwards. "The extension of the dot-dashed center axis 8, which is defined by the ring cross section, intersects the center of gravity area of the barrel 9, not shown in the drawing.
