To all whom it may concern-.-
Be it known that I, TRUMAN J. Gnovnn, a citizen of the United States, and a resident of l\-:lilllmrn, in the county of Essex and State of New Jersey, have invented a new and Improved Label-Handling Mechanism,
of which the following is a full, clear, and
This invention relates to improvements in adapted for co-action with an automatic record press and so designed that labels may be expeditiously and accurately handled.
The invention contemplates the provision of means for picking up a label from a stack, transferring itto an adjacent table, and dropping it, and further objects of the invention are to provide simple, practical and efficient mechanism for carrying out this series of operations.
In the operation of presses for molding disc phonograph records, it is customary to manually remove the two top-most. labels from a stack and lay them on the co-acting die surfaces of the press before the plastic record forming material is inserted between the dies. The finished record includes a label on each face. Inasmuch as the presses are operated at great speed and the gummed labels are very difiicult to separate, considerable difficulty involving a loss of time in the operation of the presses hasbeen encountered in manually picking up the labels and laying them on the dies. It is primarily to overcome this difficulty that the present mechanism has been devised. It will. of
course, be understood that'the invention may have. other and broader applications.
In the accompanying drawings,
Fig. 1 isa view principally in elevation of my improved label handling mechanism, parts being broken away and in section for clearness,
Figs. 2 and 3 are similar views, showing successive positions of the mechanism as it is operated to remove. the top-most label from a stack and deliver the same on an adjacent table, and
'- fice for the operation of all.
Fig. 4 is a. transverse sectional View on the staggered line 4 4 of Fig. 1.
Referring with particularity to the drawings, it will be noted thatl have used the supporting frame work for my improved mechanism. Thls frame Work may consist, as shown, of a palr of parallel horizontal reference character 10 to designate general bars 11 between which are arranged transverse connecting bars 12 A table 13 ,upon which labels are to be delivered, is hung from the frameworkin any convenient arock shaft 20 is borne by the hangers.
Near their opposite ends, the sleeves 18 support a cross bar 21, upon which the intermediate portion of a lever 22 is fulcrumed.
A spring 23 anchored t0 the rear frame bar 12 and connected to the cross bar 21, serves to normally retain the sleeves 18 and the mechanism which they carry in the position shown in Fig. 1, with the'ends of the sleeves abutting against stop nuts'24 at the rear ends of the guide rails 17.
As seen most clearly in Fig. 4, brackets 25 turnable upon the rock shaft 20 carry hollow arms 26, to the forward ends of which are attached suction cups 27.
I have indicated afplurality of =arms26 and cups 27 for simultaneously transferring the uppermost labels from a plurality of different stacks. All of these arms are controlled by the same mechanism and operate in exactly the same manner, and a detailed description of the operation of one may suf Each arm 26 is connected at its rear end to a flexible tube 28, which is in turn connected to an air pump 29. The same pump ,may be used in simultaneously controlling all of the suction cups. It will be noted that the'pump 29 includes a piston 30 working in the pump .cylinder, the rod 31 ofthe piston being operatively connected to a crank shaft 32. On the up stroke of the piston, suction 40 bar 35 effectsturningnof the rockshaft' 20,
will be produced in all of the cups 27 and on the down stroke of the piston, air willbe 'forced through the cups.
Referring now to the mechanism for con trolling the mechanical movements of the arms 28, it will be seen that the lower end of thelever 22 has a slot and pin connection with a latch bar 35 fixed intermediate its ends to the rock shaft 20. The opposite end of the latch bar is formed with a latch 36 normally retained by a keeper 37 (Fig. 1); Rocking movement of the lever will effect elevation of the forward'end of the latch bar, and consequent releaseof the' latch to permit forward movement of the sleeves 18 along the guide rails. Lever 22 is formed with an upwardly extending substantially U-shaped portion40, one extremity of which carries a yieldingly mounted buffer 'pin 41 disposed in the path-of a travelling actuator bar 42.
The weight of the arms 26 ordinarily causes the suction cups to rest upon the stacks of labels 15 in the receptacle 14, but
means is provided for elevating the cups and moving them over the tables 13. This means cons'istsof lifting cams 43 fixed upon the shaft 2-0, and carrying laterally projecting pins 44 which engage under the arms 26 to effect elevation thereof. i v I The pump 29 is of course operated in timed relationship with an actuator bar 42 and the-manner of operation of themecha- -'11 is1n'--may be briefly described as follows.
Actuator bar 4=2 travelling from the position -shown in Fig. l to the position shown in Fig. 2 engages the yielding buffer 41, rocking the lever on its fulcrum until it en-.
gages the stop and consequently releases the latch 36. The movement of thelatch and consequently moves the pins 44 of the lifting cams into engagement with the arms 26,;turnin-g the 'bracketsw25 on the rock shaft, and elevating the suction cups.
'A's-seen in Fig. 2, the piston 30 of the pump29 is on its. up stroke when the actuator bar engages the buffer so that as the suction cups are lifted, they carry (with them i theuppermost label from each sack. Continued movement of the actuatoi bar moves (the mechanism controlled by. the lever 40 to the position shown in Fig. 3, the sleeves 18 "sliding forwardly on thebars, carryingwith them thehangers 1'9 and the shaft 20 which they support, andmoving the suction cups 5 over the table'13.
26, and consequently effecting release of the- When the actuator bar reaches this position, thepiston 30 of the pump is moving towardthe 'bottom'of the cylinder, forcing air through the'tubes 28 in the hollow arms labels from the suction. cups, causing the labels to drop upon the table. As the bar I.
42 ret urns. from the position of Fig. 3 -to that shown in F ig.v 1, the spring 23 will return the sleeves 18 to their normal position, the combined weight of lever 22, arms 26 and latch bar 35 co-operating to restore the latch bar to the position shown in Fig. 1, and permitting the suction cups to again rest on the topmost labels of the various stacks The means for synchronizing the operation of the pump and the actuator bar forms no part of the present invention, and
obviously, any means might be utilized for this purpose. 1 v
