7 Claims. (Cl. 214-18) This invention relates to article-handling apparatus, and more particularly to apparatus for drying transmitter bridges.
An object of the invention is to provide new and improved yapparatus for handling articles.
Another object of the invention is to provide a new and improved apparatus for drying transmitter bridges.
A further object of the invention is to provide a simple and effective apparatus for drying transmitter bridges.
An apparatus illustrating certain features of the invention may include a guideway in the shape of an inverted U having latching means at one end thereof and escapement means at the other end thereof. A fork through which disc-shaped articles are advanced by a conveyor belt is movable from a position below the first-mentioned end of the guideway to a position moving the article into the guideway, and actuating means are carried with the fork to actuate the escapement means to release an article from the guideway as the fork pushes another article into the guideway. There also is provided drying or heating means for heating the articles as they are advanced along the guideway.
A complete understanding of the invention may be obtained by the following detailed description 'of an apparatus forming a specic embodiment thereof, when read in conjunction with the appended drawings, in which Fig. l is a fragmentary, front elevation of an apparatus forming one embodiment of the invention with portions thereof broken away;
Fig. 2 is a side elevation of the apparatus shown in Fig. l;
Fig. 3 is an enlarged vertical section taken along line 33 of Fig. l;
Fig. 4 is an enlarged horizontal section taken along the line 44 of Fig. 2;
Fig. 5 is an enlarged horizontal section taken along the line 5 5 of Fig. 2;
Fig. 6 is an enlarged vertical section taken along the line 6 6 of Fig. 5;
Fig. 7 is a vertical section similar to that shown in Fig. 6 with portions of the apparatus shown in different positions; and
Fig. 8 is a fragmentary top plan view of the apparatus shown in Fig. l.
Referring now in detail to the drawings, there is shown herein a dryer for drying transmitter bridges 10 which have rim portions 11 and projecting or boss portions 12 of a lesser diameter than that of the end rim portions 1.1. After small parts (not shown) have been cemented to the bridges 10, the bridges are advanced by a belt 13 to the right, as viewed in Fig. 2, and advance each bridge into a forli 14 having a guideway 15 and shelves or tines 16 designed to receive the rim of the transmitter bridge 10 thereon. The fork 14 is provided with a stop 17 to properly position each article 10 and is carried by an arm 18 of a plate 20 mounted slidably on guide rods 21 having adjustable nuts 22, acting as stops to limit the movement Patented Nov. 11, 1958 ICC of the plate 20 thereon. The plate 20 is fastenedrigidly to a piston 31 operable by a pneumatic cylinder 32.
When the piston 31 is raised by air under pressure admitted to the bottom of the cylinder 32, the bridge 10 carried by the fork 14 is moved upwardly past springpressed holding arms 37 and 38 into four guide rods 39, 40, 41 and 42. The guide rods are mounted by blocks 45, 46, 47 and 48 securedby brackets 51 and-52 (Fig. l) to walls of a housing 53 having an entrance opening 54 and an exit opening 55. The blocks 45, 46, 47 and 43 have openings therethrough, illustrated by an opening 55 in the block 45, which provide clearance for passage of the bridges 10 therethrough, and also are provided with grooves 56 for holding the rods 39, 40, 41 and 42 in proper guiding positions for the bridges 10. The rods extend parallelly in a U-shaped path through the housing 53 and the bridges 10 are guided along that path. Infrared ray lamps 60 are mounted in the housing 53 and direct heating rays toward the bridges 10 as the bridges travel along the guide rods so that the portions of the bridges cemented together previously are thoroughly dried.
The block 45 mounts the latching arms 37 and 38 pivotally thereon through pins 63, and leaf springs 64 press .the arms 37. and 38 toward one another. The arms 37 and 38 are provided with cam portions 65 and hook portions 66. The cam portions 65 permit a bridge 10 to force the arms 37 and 38 away from one another as the bridge 10 is moved upwardly by the fork 14, and the hook portions 66 are pressed under the bridge as it is moved therepast to retain the entire column or stack of bridges 10 after the fork 14 has been lowered away from the column.
The block 48 forms portions of an exit escapement 71 which is mounted at the exit end of the guide rods 39, 40, 41 and 42 directly above a discharge chute 72. The escapement 71 (Figs. 4, 5, 6 and 7) has top escapement arms 78 and 79 which are mounted pivotally on pins 80 and 81 secured to a bracket 82 in fixed positions. The arms 78 and 79, which are provided with relieved portions 484 and 85, normally are pressed by a tension spring 86 in ysuch directions that'the relieved portions84 and 85 are open sufciently that a bridge 10 may pass freely between the arms 78 and 79 and portions 87 and 8S of the arms 78 and 79 abut one another to limit the opening of the arms 78 and 79. The arms 78 and 79 also are provided with conical notches 91 and 92, respectively, mounted in alignment with a tapered pin 93 (Fig. 4). When the pin 93 is moved upwardly into the notches 91 and 92, it forces the end portions 87 and 88 of the arms 78 and 79 apart to thrust the relieved portions 84 `and S5 and the arms toward one another sufciently that the arms 78 and 79 will not permit a bridge to pass therebetween.
When the plate 20 is raised to lift the fork 14, it also lifts pins 93 and 108, and the pin 93 is mounted in a position in which it will engage the levers 78 and 79 prior to engagement with the levers 98 and 99 by the pin 108. As the pin 93 is so raised, it forces the arms 78 and 79 from their open positions in which they permit the bridges to pass therethrough to their closed positions in which they extend below the column of bridges 10 except for the lowermost bridge 10. Then the pin 93 holds the arms 78 and 79 in their closed position as the pin 108 is moved up into the notches 102 and 103 in the arms 98 and 99 and moves the relieved portions 100 and 101 of the arms apart to a position permitting the lowermost bridge 10 which is supported by the arms 98 and 99 to drop into the chute 72. Then as the plate is automatically lowered, the pin 108 moves away from the arms 98 and 99 before the pin 93 releases the arms 78 and 79 so that the arms 98 and 99 reclose before the arms 78 and 79 reopen to drop the entire column of bridges 10 onto the arms 98 and 99. The spacing between the arms 98, 78 and 79 and 99 is just slightly greater than the thickness of the rims 11, and the thickness of the arms 78 and 79 is slightly less than the thickness or height of the boss portions 12 of the bridge. Bushings 121 (Fig. 7) serve to separate the arms 78 and 79 from the arms 98 and 99 and the pins 80 and 81 (Fig. 5) have threaded upper ends (not shown) which thread into sockets in the block 48 to support the entire escapement structure. Heads 122 of the pins 80 and 81 serve to support the arms 98 and 99 thereon.
Operation The conveyor belt 13 is moved to the right, as viewed in Fig. 2, and moves the bridges 10 one at a time onto the fork or scoop 14. As each bridge 10 moves into the fork it is stopped by the pins 17 and actuates through the plunger 28 and the microswitch 29 to start the cylinder 32 by well-known means (not shown) to reciprocate once the piston 31 and the plate 20 mounted thereon. As the plate 20 is moved up to move the fork 14 up, the fork 14 lifts the bridge 10 beyond the latching portions 66 of the arms 37 and 38 which pushes the entire column of bridges 10 through the guide rods 39, 40, 41 and 42. Also, as the plate 20 moves up, the pins 93 and 108 sequentially actuate the escapement arms 78 and 79, and the escapement arms 98 and 99 to close the arms 78 and 79 and open the arms 98 and 99 and drop one bridge onto the chute 72. Then as the plate 20 is lowered, the arms 98 and 99 are rst reclosed and then the arms 78 and 79 are opened to permit another bridge 10 to drop onto the arms 98 and 99.
The above-described apparatus is highly eifective for drying transmitter bridges after parts thereof have been cemented together, and it is very sure in its operation, while being inexpensive in construction, maintenance and operation.
It is to be understood that the above-described arrangements are simply illustrative of the application of the principles of this invention. Numerous other arrangements may be readily devised by those skilled in the art which will embody the principles of the invention and fall within the spirit and scope thereof.
