Abstract

PURPOSE: To make a filled vessel being able to receive deforming force without hindrance when dropped by having structure that a rolling ring has the cross-sectional shape of the trapezoid, that its narrowest point is located at the bottom of a groove and increases the wall thickness toward the edge region, and that its axial end face ends in the plane of the bottom head of the vessel. CONSTITUTION: A support/transport ring 11 is integrally connected with a surrounding wall 4 of the vessel through a connection ring 15 connected to a horizontal contact face 13. The bottom of a groove between the connection ring 15 and surrounding wall portion 12 is disposed at a lower side of the horizontal face 13 with a separation. Also, the rolling ring 1 in the range of vessel bottom has the cross-sectional shape of trapezoid, its narrowest point is located at the bottom of the groove 2, forming a sort of hinges that can bend inward when a deforming force is produced sidewise, and wall thickness increases from the narrowest point toward the thick edge region. The axial end face 5 nearly ends at the plane of the bottom head 7 of the vessel, and the bottom head has shifted to the cylindrical surrounding wall 4 of the vessel through a conical wall portion 6. Therefore, the rolling ring deformed absorbs bouncing energy produced in the dropped vessel.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a barrel made of thermoplastic plastic, which includes a rolling ring protruding from the barrel circumferential wall on an axial extension of a cylindrical circumferential wall portion near the bottom of the barrel. The rolling ring is of a type in which a region of the peripheral wall connected to the bottom of the groove between the rolling ring and the barrel peripheral wall transitions into the barrel bottom in a conical shape.

PRIOR TECHNOLOGY Generally, barrels are provided with a supporting and conveying ring which is located in the barrel peripheral wall near the associated end face and which is solid in cross section, and which supports and conveys the gripper of the inserted barrel gripper. The arm has a tth horizontal contact surface and a vertical contact surface.

Most such barrels are constructed entirely as blow-molded barrels, with the supporting and conveying ring being deformed from the barrel wall and molded in one piece during manufacture. However, barrels are also known in which the tubular barrel part and one end region are manufactured separately from one another. The injection molded end region, which is provided with a supporting and conveying ring, is welded to the tubular barrel part in a subsequent working operation.

The supporting/conveying ring is extremely damaged by the relatively thin material thickness when the barrel is tilted and collides with the filling material falling from a certain height, so the supporting/conveying ring is particularly designed to absorb all of the bounce energy. The crush area must be connected. For this purpose, supporting and conveying rings are arranged at a distance below the top or bottom edge of the barrel. Furthermore, the area of one circumferential wall that protrudes beyond the ring groove t increases toward the barrel axis in a diagonal shape.

When the falling barrel is tilted or hits a drop, the upper elastic end region of the ring is deformed before it reaches the supporting and conveying ring.

Due to the relatively small distance between the support and conveyor ring and the barrel head or barrel bottom, the operator can grasp the support and conveyor ring together with his hands when rolling the barrel diagonally, thus providing the most advantageous "Handling" is obtained.

When a filled barrel is rolled diagonally, the bottom edge of the barrel is pressed flat by the weight of the barrel, thus creating a kneading effect that interferes with the transfer. By supporting the corresponding supporting and conveying ring on the barrel bottom, deformations of the barrel bottom edge can be partially prevented, thereby relieving disturbing kneading effects.

Nevertheless, barrel rolling is still strongly hindered by the lower edge. Furthermore, the corner areas at the transition from the barrel circumferential wall to the barrel bottom are relatively thin and subject to manual stress from above during rough driving, especially when rolling on an incline. Furthermore, the risk of accidents during full tilting and rolling is increased by the protruding rolling ring, for example the feet of the worker being crushed under the rolling ring.

The upper support and transport ring forms a bearing for the keg gripper into which it is inserted and is therefore used to lift and transport the keg by the keg gripper. On the other hand, the lower support/transport ring is given a different function. In this case, consideration should be given to ensuring that the deformation forces can be stopped without any disturbance when the filled barrel is dropped.

To this end, the lower supporting and conveying ring is designed as a rolling ring and is placed at a slightly different position on the barrel wall.

Means for Solving the Problem The nine means taken to solve the above-mentioned problem are that the rolling ring has a substantially trapezoidal shape in cross section, and that the narrowest point of the rolling ring is a groove in the rolling ring. located at the bottom, from this narrowest point the wall thickness of the rolling ring increases into a thicker end region, and the axial end face of the rolling ring ends in the plane of the end face of the barrel bottom. The purpose is to do so.

Effects of the Invention According to the invention, a lower crushing area is omitted, so that the barrel can only be rolled through the rolling ring.

The bouncing energy generated when a falling barrel collides with the barrel at an angle or vertically is directly absorbed by the rolling ring, which is bent inward around a narrow connection point on the barrel wall and shaped like a cone. It is transmitted to the surrounding wall portion of the wall and is elastically deformed in the trench supported there. In this form, the bound energy is
Absorbed by a modified rolling ring.

The vertical stacking forces are absorbed by the rolling ring and the barrel bottom, and the force distribution takes place over the cylindrical wall section in the rolling ring and over the conical wall section at the barrel bottom. The end face of the barrel bottom can be set back slightly from the axial end face of the rolling ring so that it can rest sufficiently on the installation floor.

When rolling an on-edge barrel, the barrel is slightly tilted. Due to the configuration of the present invention, the diagonal loads that occur across the edges during rolling can be reduced by the rolling ring starting from the bottom of the groove, sloping outward in a conical shape, and passing through the center of the rolling ring cross section. The support is advantageously stopped by the fact that the extension of the center line crosses the area of the center of gravity inside the barrel.This ensures that the rolling ring is subjected to very little bending force during the transfer and, therefore, that little deformation occurs during the transfer. A relatively narrow and confined floor rest is achieved which supports all movements.The stacking forces are introduced directly into the barrel wall via the rolling ring.

With the embodiment of the invention, an efficient punching of the barrel is ensured if the outer diameter of the radial end face of the rolling ring corresponds to the outer diameter of the outer circumferential wall of the barrel.

In the drawings of the embodiment, reference numeral 4 indicates the cylindrical peripheral wall of the barrel 9, reference numeral 10 indicates the head surface, and reference numeral 7 indicates the end surface of the barrel bottom. A barrel stopper (not shown) is provided at the barrel head.

In the vicinity of the barrel head there is a supporting and conveying support/conveyor which is solid in cross-section and has a horizontal abutment surface 13 and a vertical abutment surface 14 for the gripper arm (not shown) of the barrel gripper to be inserted.
11 is located.

The support and conveyor 11 is integrally connected to the barrel peripheral wall 4 via a connecting ring 15 which is connected to a horizontal abutment surface 13 . The bottom of the groove between the connecting ring 15 and the peripheral wall part 12 rising towards the head part 10 is formed by a supporting and conveying ring 11
are arranged at intervals below the horizontal abutment surface 13 of.

The rolling ring 1 has an almost trapezoidal cross section in the bottom area of the barrel! are doing. The narrowest point of the rolling ring 1 is located at the bottom of the groove 2. Here, in addition to a good welding of the materials upset during manufacture, a kind of hinge is formed that allows the rolling ring 1 to bend inward when lateral deforming forces occur. There is.

From the narrowest point, the wall thickness of the rolling ring 1 increases in the thicker end region.

The axial end face 5 of the rolling ring 1 ends approximately in the plane of the barrel bottom 7, which merges into the cylindrical barrel jacket 4 via a conical jacket section 6. The radial end face 3 corresponds to the outer circumferential diameter of the barrel jacket 4.

The rolling ring 1 starts from the groove bottom 2 and slopes outward in a slightly conical manner. An extension of the center line 8, indicated by a dash-dotted line, passing through the center of the cross-section of the rolling ring crosses the center of gravity of the barrel 90 (not shown).
