Definitions
- the present invention relates to a feeding device for feeding objects each having a cylindrical portion of substantially the same diameter, one by one, in the same direction and at a right angle to the axes of the objects.
- objects may be ammunition cartridges to be transported from an ammunition magazine to a hoist, cans to be filled and sealed, bottles to be labelled, etc.
- a more specific object of the invention is to provide a novel and improved feeding device which is capable of sustaining the strains and stresses to which it may be subjected due to rapid acceleration and deceleration of the feed motion, especially when the objects to be fed are comparatively heavy such as cartridges for heavy caliber ammunition.
- a still more specific object of the invention is to provide a novel and improved feeding device which is simple and rugged in design and which requires a minimum of movable components.
- FIG. 1 is a perspective elevational view of a feeding device according to the invention.
- FIG. 2 is a fragmentary detail view of FIG. 1, and
- FIG. 3 is a section taken on line IIIIII of FIG. 1 on an enlarged scale.
- FIG. 1 shows a plane base 1 upon which are mounted two parallel guide tracks 2 to define a linear feeding path.
- a plurality of objects 3 to be fed such as ammunition cartridges are placed upright upon the base and between the tracks.
- the cartridges are to be fed one by one in the direction from the left towards the right, but they may also be fed in the opposite direction as will appear from the subsequent description.
- the cartridges 3 are cylindrical except for the nose cone. While the objects'to be fed may have a variety of configurations, it is essential thateach object has a cylindrical portion and the cylindrical portions of all the objects have substantially the same diameter, as will appear more fully from the subsequent description.
- the feeding device comprises a pair of superimposed comb-shaped members 4 and 5. Two pairs of such combs are shown in FIG. 1, but in some instances only one pair is sutiicient and in other instances, for example when the objects are rather long, more than two pairs may be desirable. In any event all the pairs are alike in structure and function and, accordingly, only the lower pair of combs is described.
- the teeth 12 of the combs are separated by rounded recesses 4a and 5a which have a width and depth sufficient to accommodate the diameter of the objects to be fed.
- the two combs 4 and 5 are supported and actuated at two lengthwise spaced points.
- the two combs are engaged at the ends thereof.
- crank arm 6a which mounts a depending pin 10 rotatably extending through the respective end of comb 4 and secured to one end of a crank arm 10a.
- the other end of this crank arm mounts a depending pin 11 which slidably extends through the respective end of comb 5 and is secured to one end of a crank arm 11a.
- crank arm 11a mounts a depending pin 16 secured to one end of a third crank arm 16a, the other end of which is pivoted to a connecting rod 14.
- the other end of rod 14 is pivoted to a similar assembly as just described except that shaft 13 which corresponds to shaft 6, is not directly driven.
- crank arms 10a and 11a face in opposite directions in reference to their pivot points, that is, they are separated by an angle of 180.
- the third crank arm 16 forms an angle of with crank arms 19a and 11a.
- Pins 16, 11 and 16 are parallel to each other and normal of the plane of base 1 and the distance between pins 16 and 11 corresponds to the diameter of the cylindrical portion of cartridges 3 plus the thickness of one of the teeth 12 of combs 4 and 5.
- Shafts 6 and 13 are also normal of the plane of base 1 and disposed at a transverse distance from guide tracks 2 such that the teeth 12 extend to the longitudinal center line between the tracks when crank arms Lilla and 11a are lengthwise parallel to tracks 2. This position is clearly shown in FIGS. 1 and 3, and the latter figure also shows that the teeth 12 reach between each two cartridges placed between tracks 2.
- the feeding device as hereinbefore described, operates as follows:
- the drive imparted to shaft 6 is transmitted to the left hand assembly through crank arms 11a, 16a and rod 14, but it is, of course, within the scope of the invention to provide a separate drive for shaft 13, or to drive shaft 13 rather than shaft 6.
- the feed direction can be reversed by reversing the rotational direction of shaft 7.
- the upper and lower pair of combs are shown to be of equal configuration, but the combs of the two pairs may also have a different configuration, depending upon the diameter of the objects involved. Furthermore, the cross sectional configuration of the objects may be varied, provided only that the objects can be transported by means of combs of the kind here shown.
- a feeding device for successive and unidirectional feeding of objects each of which has a cylindrical portion of substantially the same diameter, said device comprising a plane guide base for placing thereon a plurality of objects to be fed in upright position, a pair of combshaped transport members one of which is superimposed above the other, said transport members extending parallel to said base and defining a linear path in reference to said base, each two teeth of said transport members being separated by a recess having a width and depth substantially equal to the diameter of the cylindrical portion of said objects, mounting means disposed lengthwise of said transport members supporting the members movable parallel to said base and along two semicircular paths symmetric in reference to said feed path, movement of either of the transport members through one of said semicircular paths moving the respective transport member into engagement with the objects placed upon the base and displacing said transport member lengthwise of the feed path through a predetermined distance, said semicircular movement effecting feeding of the objects through said distance, and movement of the same transport member through the other semicircular path effecting Withdrawal of said transport member from the objects
