4 Claims.
This invention relates to article feeding devices, and more particularly to a device for feeding articles singly and in spaced relation to each other.
In grading machines for eggs and the like, it is necessary that each article be handled indi-- vidually by the machine. Thus, the articles must befed onto the machine one by one, in sufficiently spaced relation to permit each individual article to be subjected to the action of the machine. Fragile articles, such as eggs, must be carefully handled and, therefore, the feeding thereof to such machines is frequently done by hand. Automatic feeding devices have heretofore been proposed but they have not been Wholly effective in operation, particularly in the handling of fragile articles, such as eggs.
,It is an object of this invention to provide a simple but effective means for feeding articles in single, spaced order, such means being adapted to handle the articles in a gentle manner whereby injury to the same is avoided. A further object is to provide a gravity feeding means for articles adapted to be actuated by the weight of the articles whereby the use of extraneous power means is avoided.
Other objects, details and advantages will become apparent as the description of the invention proceeds, with particular reference to the accompanying drawing, in which,
Figure 1 is a side elevational view, partly in section, showing the device in one position,
Figure 2 is a side elevational view, partly in section, showing the device in another position,
Figure 3 is a transverse section on line 3-3 of Figure 2,
Figure 4 is a plan view and Figure 5 is a sectional shown in Figure 4.
In the drawing, the device is shown as adapted to feed eggs or like articles onto the runway of platform I, which may be a part of a grading device, not shown.
The device comprises a base 2 adapted to be fixed in relation to the grading machine or other apparatus with which the device is to be used, and an adjustable base member 3 hinged at i to the fixed base 2. The member 3 is normally supported in inclined relation by the bolt 5 mounted in the base 2. The bolt 5 is adjustable to vary the angle of incline of the member 3.
Mounted on the member 3 is a fixed article track or runway 6 adjacent the end remote from the platform I, and a tiltable article track I of a detail of the device,
elevation of the detail extending from a point closely adjacent the end of track 6 to a point closely adjacent the runway I. The fixed runway la is carried by a'support 8, which supports the runway in a somewhat elevated position with respect to the base memher 3. In order to prevent injury to any article which may be accidentally dislodged from the runway 6, a guard platform t, with upturned lateral flanges II) and preferably lined with a resillent material II, such as rubber, extends along either side of the runway.
The tiltable track I is pivotally supported at one end, as indicated at I2, on a lug or lugs I? mounted on the base member 3. A bar it has one end pivoted at I5 to lugs I6 on the under side of track I, such pivot point being located at a point which is spaced from the pivoted end of the track a distance roughly one-third the length of the track. The other end of bar Id, which may rest normally on the member 3, has an unturned finger II, which projects between the adjacent ends of tracks 6 and I. It will be observed that, in the normal position of the bar, as shown in Figure 1, the end of finger =Ii does not project above the upper surface of the tracks so that an article may move from one track to the other. A post I8, also mounted on the member 3, engages the lower surface of the bar at a point adjacent its pivot point and spaced therefrom a distance roughly one-quarter more or less the length of the bar. Means for adjusting the height and relative position of the post with respect to the end of the bar are preferably provided. As shown in Figures 4 and 5, the post is screw-threaded in a plate 20, a lock nut 2I being provided to maintain it at any adjusted height. The plate is mounted on the base member 3 by means of screws 22 which extend through longitudinally extending slots 23 in the Thus, the plate and the post carried thereby may be moved forward or backward, as desired, by loosening the screws 22, which may subsequently be tightened to lock the plate and post in any desired position.
It will be observed that the equilibrium of the device is such that, in the normal at rest position thereof, as shown in Figure l, the track 1 is maintained in substantially the same plane as track 6 with their adjacent ends in opposing relation, the bar I4, supported as described, acting to hold the track I in such position.
The track I is provided with lateral guard rails I9 to prevent accidental dislodgment of articles thereon.
In operation, the base member 3 with its supplate.
ported elements is set at a desired inclination, which is preferably just sufiicient to cause positive movement by gravity of articles along tracks 6 and I in any position of the latter. The articles 24 to be fed are placed on the track 6 as shown in Figure 2. As the foremost article moves from track 6 into engagement with the end of track 1, the latter is immediately depressed about its pivot l2 under the weight of the article. Such depression of the track immediately causes upward movement of the adjacent end of bar I 4 and finger I"! because of the engagement of post l8 therewith. The finger l1 projects between the ends of tracks 6 and I and prevents the succeeding articles on track 6 from moving forward onto track 1. It will be observed that only a very slight downward movement of the end of track 1 is necessary to cause upward movement of finger I! into article arresting position.
As the article on track 1 reaches the position, which is roughly that indicated in dotted lines at 24', the device returns to its normal position, as in Figure 1, and another article is fed onto track 1, as previously described. The spacing of the articles being fed may be varied as desired by moving the plate backwardly or forwardly to alter the point of engagement of the post with the bar H.
The device described constitutes an efiicient and accurate feeding device for eggs and the like. Movement of the various parts is such that possibility of injury to fragile articles issubstantially avoided. The provision for convenient and rapid adjustment of the various parts is an important feature of the invention in that the device may be readily maintained in useful operation. The arrangement of parts, while quite simple, is such that sensitive, positive operation is achieved.
It will 'be apparent that many details of structure may be altered without departing from the spirit and scope of the invention as defined in the appended claims.
