Abstract

A locator for retaining the end 11 of the spindle 10 of a conveyor roller 30 in a conveyor frame 20 to allow easy removal and replacement of the spindle 10, comprises a U-shaped member 2-8 formed of a plastics material and having a first C-shaped element 3-6 that is received in a groove formed in the end of the spindle 10 on one side of a conveyor frame 20 and a parallel element 8 extending alongside the face of the spindle 10 on the other side of the frame 20. A further arm may extend from the top of the parallel element 8 in a direction generally parallel to the spindle 10 to a point near the rear wall of the frame 20 to prevent transverse movement of the spindle. <IMAGE>

Description

SPECIFICATION Spindle locator The present invention relates to means for locating the ends of a spindle in a support.
In many circumstances it is necessary to be able to remove a spindle from its support for the purpose of replacement. Thus in roller conveyor systems a fault in a roller, or its bearing, carried on a spindle the ends of which are located in a frame, means that the complete roller asembly has to be removed and replaced.
Methods currently used to locate the ends of a spindle in their supports, for example a conveyor frame, make removal and replacement difficult.
We have now developed a simple means for the location of the ends of a spindle in a support comprising a U-shaped member including a substantially C-shaped first element capable of engaging the end of a spindle and extending more than halfway around the circumferential periphery thereof, and a second element spaced from the first element and including a portion parallel to said first element and extending across an end face of the spindle when the said first element engages the spindle.The use of a locator of this type is restricted to spindle supports in which the support member includes a flat plate portion containing an aperture in which the spindle engages, the member having an edge portion adjacent to said spindle whereby the first element of the locator is positioned one side of the said plate portion and the portion of the second element parallel to said first element is positioned on the other side of the plate portion.
Optionally the locator may further include a third element extending from the second element in a direction having a component parallel to the horizontal axis of the spindle and extending for a distance whereby the free end thereof is adjacent a second portion of the spindle support. Such a locator may have both element positioned on the side of the support member adjacent the end of the spindle.
Embodiments of the present invention will now be described with reference to the accompanying drawings in which: Figure 1 is a diagrammatic representation of a first embodiment of the invention, Figure 2 is a diagrammatic illustration of the use of the embodiment of Fig. 1 for supporting a spindle in a conveyor frame, Figure 3 is a diagrammatic representation of a second embodiment of the invention, Figure 4 is an illustration of the use of the embodiment of Fig. 3 to locate the end of a spindle in a conveyor frame, and Figure 5 is an alternative form of the embodiment of Fig. 3.
Referring to Figs. 1 and 2 of the drawings.
A locator for end 11 of spindle 10, and generally indicated at 1, comprises a first element (2) consisting of two parallel arms (3) and (4) having inwardly directed end portions (5) and (6) and a second element (7) having a flat plate portion (8) extending parallel to element (2) and spaced therefrom to define a channel portion (9). The locator may be formed from a plastics material such as Delrin, nylon or other resilient material, arms (3) and (4) being dimensioned to be a snap fit onto the end (1 1) of the spindle (10); In use, as diagrammatically illustrated in Fig. (2), end (11) of spindle (10) carrying a roller assembly (30) is supported in the depending plate portion (21) of one side of a conveyor frame (20) by location in hole (22).Locator 1 is positioned such that the first element (2) is positioned on the roller side of member (21) of frame (20) with portion (8) of element (7) extending parallel to the end face (12) of spindle (10) the edge of portion (21) of frame (20) being received in channel (9) of locator 1.
An identical locator is positioned at the other end of spindle (10) thereby ensuring that transverse movement of the spindle in the two conveyor frames is restricted. Since the locator is made of resilient material it can easily be "snapped off" from each end of the spindle to allow ready removal and replacement from and into the conveyor frame.
An alternative form of locator is shown with reference to Figs. 3 and 4 in which the locator, generally indicated at 100 includes a first element 102, having arm portions 103 and 104, with inwardly directed end portions (105) and (106). Second element (107) includes a portion (108) parallel to element (102) and a third portion (109) extending rearwardly from portion (108) towards the vertical wall (23) of conveyor frame 20. In use the locator is snapped onto the end (11) of conveyor (10) that projects through hole (22) in depending portion (21). Portion (108) of element (17) extends parallel to end face (12) of spindle (10) and portion (109) extends towards the rear wall (23) of frame (20). Similar locators are positioned at either end of spindle (11) and portion (109) is dimensioned such that transverse movement of spindle (10) is restricted to prevent either end of the spindle being removed from the conveyor until the locator is "snapped off".
Fig. 5 shows an alternative embodiment of the locator of Fig. 3 in which element (103) has arm portions (114) and (115) shaped in a Z configuration to be a snap fit over the end of spindle (10); such an embodiment may conveniently be manufactured from spring steel.
Clearly, the ends of the conveyor may be suitably grooved to accept the arm portions of elements (2) and (102) of the embodiments of Figs. 1 and 3 in which case the said elements will act as circlips. Further the locator is suitable for use with spindles having a round or hexagonal cross-section.

Claims (5)

1. Means for locating a spindle end in a support comprising, a substantially U-shaped member in which one arm provides a first Cshaped element for engaging the spindle end and dimensioned to extend more than halfway around the circumferential periphery thereof, and the other arm provides a second element spaced from said first element in a direction parallel to the spindle axis and including a portion parallel to said first element and dimensioned to extend across an end face of the spindle when the first element is in engagement therewith.
2. Means according to claim 1 wherein a third element extends outwardly of said member in a direction having a component parallel to the spindle axis.
3. Means according to claim 2 wherein the third element extends from the top end of said second element.
4. Means according to any one of claims 1, 2 or 3 wherein the said first element includes arm segments having a Z-shaped configuration.
5. Means according to any one of claims 1-4 formed from a resilient plastics material or a spring steel.
