Application July 26, 1944, Serial No. 546,641
(Cl. i4-469) Claims. l
'Ihis invention relates to improvements in switch operating mechanism, and particularly is directed to switch operating mechanisms for closing or opening an electric circuit to actuate any desired electrically operated device.
The present invention is particularly well adapted for use in article handling machines, wherein the articles are continuously advanced and wherein it is desired to periodically actuate mechanism for performing some function on or with respect to the moving articles. For convenience of description the invention will be described in connection with one of its many uses, that of successively stamping or marking the articles as they move past a predetermined station.
In article handling machines of the character mentioned provision is made for carrying or conveying the articles continuously from station to station and out of the machine on carriers or conveyors of suitable types. It is often desired to print or stamp or otherwise apply information on the articles or on packages containing articles as they are continuously advanced along a conveyor or as they are moved out of the machine. It may be desired to perform such operation not only while the articles are in motion but also while they are at rest.
One of the objects of the present invention resides in the provision of a switch operating mechanism adapted to be actuated by a continuously moving object or series of objects successively wherein provision is made for throwing a switch on and off or olf and on.
Another object of the present invention resides in the provision of an article controlled or oper ated means which is operated automatically by articles during their travel in a predeterminedA path.
Another object of the invention resides in the provision of apparatus of the character indicated which is automatically operated by articles irrespective of the shape or size of the articles or the irregularity of the spacing of the articles dur ing their travel.
A further object of the invention resides in the provision of declutching, or slip connection between actuating members.
A still further object of the invention resides in the provision of improved means for adjusting or limiting the movement of the switch plunger contacting means whereby to select, vary or adjust the time interval the switch is on or off.
Other objects of my invention will be manifest from the following description and the accompanying drawing, in which,
Fig. l. is a plan View of an article handling machine showing my improved switch operating mechanism in position thereon;
Fig. 2 is a front elevational View of my im proved switch operating mechanism;
Fig. 3 is a horizontal sectional view on the line 3 3 of Fig. 4; and
Fig. 4 is a vertical sectional View on the line 4 4 of Fig. 2.
For the purpose of disclosure I will describe my invention as a means for operating a microelectric switch which may be employed to control or operate a printing device for printing on the articles in transit.
Referring to the drawing in detail the letter A designates a frame of an article handling machine which may include tracks 8 on which articles or packages 9 are conveyed by means of a belt I Il.
My improved switch operating mechanism, generally indicated at B is provided to operate a micro-electric switch C, which is Xed in a box-like housing I5 attached to a bracket I 6 suitably secured to the frame of the machine as indicated in Figs. 1 and 2, The switch plunger Il is engaged and operated by an arm I8 rotatively supported on a rockable shaft 20. The shaft is provided with a fixed collar 2| and a spiral driving spring 22, between the arm I8 and the shaft 2d, normally holds the arm I8 against a pin 23 on the collar 2|. As shown in Fig. 3 a helical compression spring 25 is provided to move the arm I8 counterclockwise to permit the switch to open.
The shaft 20 is mounted in the bottom wall of the box I5 and is journaled in a journal `bearing 62, threaded into a projection 3I on the bottom wall of the box.
Secured upon the lower end of the shaft 2G is an arm 35 which is preferably of hexagonal cross section and is provided with an opening receiving the end of the shaft 20 which may be split as shown at 36 in order that it may be clamped on the shaft in any desired position by means of a threaded clamping bolt 31.
Journaled in the bracket I6 is a shaft 40, the lower end of which is enlarged as shown at 4I forming a shoulder bearing against the lower face of the bracket and the upper end of which is surrounded by a collar 42 which bears against the upper face of the bracket and against which `bears a nut 43 threaded on the shaft 40 and locked in position by a nut 44.
Secured on the lower end of shaft 40 is the main operating or driving arm 45, which, as
shown in Figs. l and 3 extends into the path of the moving articles 9, This arm is provided with a round hole 45 in which is seated a ball clutch i? of slightly larger diameter than the hole and which is held seated by a leaf spring 48 secured against the lower face of the arm 45. 'I'he ball l? extends through the arm far enough to engage and drive the arm 35 as it is moved past the arm in a clockwise direction. The arm 35 will be returned in a counterclockwise direction to its normal position by the spring 25.
Figs. 1 and 3 show the relative positions on the shafts supporting these arms and the relative positions of the arms in their normal position. The normal position of the driven arm 35 is determined by the spring 25 and the normal position of the arm 45 is determined by a tension spring 53, Fig. 3 made adjustable by a bolt 54 passing through a slot 55 in a lateral extension on the bracket I5. The adjustment is maintained by a nut 55 threaded on the bolt 54.
As the driving arm 45, Figs. 1 and 2, is moved clockwise by a moving article 9, the ball 41 engages the right hand upper corner or side face of the driven arm 35 carrying this arm in a clockwise direction until the switch is closed, the limit of the clockwise movement of the arm 35 being adjustably controlled by a stop 6U as is obvious from Figs. 1 and 3. The stop 50 is threaded by means of a ne thread in a lug 6| projecting laterally from a plate 62 to provide a fine or Vernier adjustment The plate 62 may be adjustably positioned on the forward face of the housing I for coarse adjustment purposes. For this purpose the plate 52 is provided with open ended slots 53 through which pass threaded studs 64 to secure the plate 52 in adjusted position against the face of the housing. The duration or time interval the switch is on is adjustable by means of the stop 60, whereby the length of the current impulses may be selected, varied and/ or adjusted to a fraction of a second if desired.
ri`he plate B2 is also used for clamping of a stop member i9 against the front face of the housing I5. This stop member includes a laterally projecting member 'II extending into the path of the driving arm 45 and limiting the counterclockwise movement or overthrow of the arm 45 when it is returned by its spring 5D. The forward movement of the switch operating arm 35 will be stopped when the switch is closed, but the driving arm 45 will be carried farther in a clockwise direction by the article. The switch operating driven arm 35, however, will be immediately returned by its spring 25 to release the switch and thence move it into its normal position. To permit and facilitate the movement of the driven arm 35 past the driving arm 45 on its return movement into normal position, the left hand corner or side face of the arm 3-5 as viewed in Fig. 3, is cut away to provide a shallow bevelled track or cam face, as indicated at in Fig. 4.
rThe box-like housing I5 may be closed by a cover plate 'IE5 as shown in Figs. 1, 2 and 4.
In operation, an article or package, carried on the conveyor I0 between the guard rails 8 moves toward the left, as viewed in Figs. 1 and 3, into engagement with the driving arm 45, whereupon the arm 45 will be rotated in a clockwise direction. After a short movement of the arm 45, the ball 4i engages the right hand corner or side face of the driven arm 35 and rocks this arm clockwise against the stop E0 into the first broken line position shown in Fig. 3. This actuates the micro-electric switch C to open or close the same as the case may be. As the arm 45 continues its clockwise movement toward the second or nal position indicated by broken lines in Fig. 3 the ball 41 rides over the right hand corner` of the arm 35 freeing the arm 35 which is immediately returned to its normal position by the spring 22. When the arm 45 is released by the traveling article, it is returned to its normal position shown in full lines in Fig. 3, by its spring 50. The movement of the arm 45 past the arm 35 into its normal position shown is facilitated by the shallow bevel or track 'I5 in the arm 35. It will be appreciated that on the return movement of the arm 45 the switch is not actuated.
It is to be understood that the circuit which is opened or closed by the micro-electric switch may be used to operate or control any mechanism, to perform any desired operation, on any of the moving articles, or on any device other than the moving articles,
It is also to be understood that the driven arm 35 or the plunger actuating arm I8 may be employed to operate light operating mechanical parts, if desired. In a broader aspect of this invention, the driving arm 45 may be operated by any means other than by moving articles as illustrated and described. For example the switch may be manually operated by the hand or the foot of the operator. In foot operation of switches as at present constructed the operator must move a treadle in one direction to close the switch and in the other direction to open the switch. When my present invention is employed for manual operation a single movement of the hand or foot of the operator in one direction both closes and opens the switch, the advantages of which Will be readily appreciated.
As will also be obvious certain features of my invention are applicable to other types of reciprocating or oscillating driving and driven members adapted to move back and forth.
