I, l! I g I! I Ii 9 f4? 4 ii 3 1 7 CONVEYOR ROLL ARRANGEMENT BACKGROUND OF THE INVENTION The invention relates to conveyor roll arrangements, and relates more particularly to a conveyor roll that includes a hollow roll body that is joumalled for rotation about an immovable roll axle. More particularly, the invention relates to such an arrangement in which the roll axle ends are supported substantially perpendicularly to the direction of elongation of two elongated supports.

Conveyor rolls of this type are mounted in roll conveyors, for instance for transporting holding or casting boxes in foundries, or in conveyor systems for transporting piece goods.

Conveyor rolls are known in which the ends of the roll axles are guided in recesses which are established in laterally arranged supports, and have means to restrain axial and radial movement. Constructions are furthermore known in which the ends of the roll axles are provided with surfaces and with holding means cooperating therewith.

These constructions of the prior art have, however, the disadvantage that the elements needed for these constructions are expensive to manufacture.

SUMMARY OF THE INVENTION It is accordingly among the principal objects of the invention to provide a conveyor roll arrangement which is characterized by a minimum of parts with attendant savings in cost.

It is another object of the invention to provide such a con veyor roll that is easy to mount effectively and in exact predetermined position.

Further objects and advantages of the invention will be set forth in part in the following specification and in part will be obvious therefrom without being specifically referred to, the same being realized and attained as pointed out in the claims hereof.

With the above and other objects of the invention in view, the invention consists in the novel construction, arrangement and combination of various devices, elements and parts, as set forth in the claims hereof, certain embodiments of the same being illustrated in the accompanying drawings and described in the specification.

Broadly speaking, the instant invention provides for clamping of the opposite roll axle ends in apertures of normally substantially equidistant, normally substantially parallel plates which are mounted on the respective support which, together with adjusting means, such as adjusting screws, form clamping means for the effective clamping in exact predetermined position of the roll axle ends.

The instant invention furthermore provides for mounting the rims on the roll body ends by metal binding means and/or metal bonding agents.

BRIEF DESCRIPTION OF THE DRAMNGS For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description, taken in connection with the accompanying drawings, in which:

FIG. 1 is a fragmentary sectional view of a conveyor roll arrangement in accordance with one embodiment of the invention;

FIG. 2 is a fragmentary side elevational view, on a smaller scale, as compared to FIG. 1, of a plurality of conveyor rolls in accordance with the embodiment of FIG. 1; and

FIG. 3 is a fragmentary sectional view, on a scale and in its arrangement similar to that of FIG. 1, but embodying a modification.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In carrying the invention into effect in the embodiments which have been selected for illustration in the accompanying drawings and for description in this specification, and referring now particularly to FIG. 1, there is provided a conveyor roll arrangement that includes a cylindrical hollow roll or roll body 1 that carries near its opposite ends rims 2 and 2'. The rims 2, 2', are mounted on the roll 1 by means of a well known conventional metal bonding agent.

The roll 1 has an off-set rolling surface 15, and in the off-set portions is provided with vent holes 19. Near both ends, the hollow roll body 1 mounts conventional, suitable ball bearings 12 which are pressed into the ends of the hollow roll body 1, and which are mounted on the opposite ends 4 of an immovably held roll axle 3. Each ball bearing 12 is held axially, on one hand at its retaining ring by means of a spacer ring 13 that is seated against a shoulder that is formed on the interior of the roll body 1, and at its inner ring by means of an adjusting ring 10. Each of the adjusting rings 10 is connected to its respective roll axle end 4 by means of a set screw 11, and furthermore has its bore, with which it surrounds the external surface of the roll axle end 4 bonded to said end 4 by a suitable bonding agent. A play 16 is provided between the shoulder of each adjusting ring 10 and the inner ring of the ball bearing 12 adjacent thereto.

The roll axle ends 4 are connected, with the axis of the roll axle 3 disposed perpendicularly to two supports, such as angle irons, 7 in the following manner. Each support 7 has a beam engaging portion 17 and a portion at right angle thereto which defines a surface 14. The surface 14 is parallel to the portion 17. Apertures or bores 5 and 5' are provided in plates 6 and 6', respectively, and are substantially aligned. The plates 6 and 6 are normally substantially equidistant and normally substantially parallel to each other on each support 7. Bolts or screws 9 connect the plates 6 and 6' of each support 7 to the respective support. The plates 6 and 6 furthermore are provided with adjusting means, such as adjusting screws 8 which, together with the plates 6 and 6' and the apertures 5 and 5' constitute clamping means for the respective roll axle end 4.

In FIG. 2 there is shown a series of rolls 1, constituting a portion of a roll conveyor.

OPERATION The operation of the above described embodiment has been described hereinabove. The roll body 1 is mounted on the ball bearings 12 which, in turn, are mounted on the ends 4 of the roll axle 3. The ball bearings are secured against disengagement. Each roll axle end 4 is supported on a surface 14 of the support 7 and in the substantially aligned apertures 5, 5' of the plates 6 and 6 which are mounted by the screws 9 on the support 7. For clamping the roll end 4, the operator will adjust the plates 6 and 6' by means of the adjusting screws 8.

In the modification of FIG. 3, similar parts have been provided with the same reference numerals as in the preceding views. A driven pinion 18 has been mounted near one end of the roll body 1, which serves for rotating the roll body 1 about the axis of the roll axle 3. The pinion 18 is mounted near the rim 2 or 2', requiring moving of the rim further away from the end of the roll 1 than in FIG. 1.

The operation of the modification of FIG. 3, except for providing for the driving pinion 18, is in other respects similar to that of the embodiment of FIG., 1.

Certain of the advantages of the invention have already been herein referred to. It may be useful, however, to allude particularly at this point, to the simplified production possibilities afforded by the instant invention and the attendant low production cost. The instant invention furthermore has been found to be a particularly desirable type of mounting for the roll axle 3 and the roll 1 and aflords simple operational steps, partly as described in the foregoing and partly as self-evident from the preceding description.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

Having thus described the invention, what I claim as new and desire to be secured by Letters Patent, is as follows:

1. A conveyor roll arrangement, for use in connection with two elongated supports,

comprising in combination,

a roll axle being adapted to be supported imrnovably from said supports with the axis of the roll axle disposed substantially perpendicular to the direction of elongation of said supports,
