JAMES MJKUSS P W BM-J AT TORNEYS REGISTRATION CONTROL FOR SUPERPOSING' COMPLEMENTARY IMPRINTS FIELD OF INVENTION This invention relates generally to apparatus and methods for hot stamping a plurality of imprints to make one composite imprint, and specifically to precise control of registration of the imprints with each other.
DESCRIPTION OF THE PRIOR ART a second heated die transfers a superposed complementary imprint on the first imprint. The movement of a continuous strip of material to receive successive imprints by'the use of rollers is invariably attended by slipping of the material over the pull roller, so that longitudinal registration is lost. Also, the continuous strip of material may wander latitudinally with respect to its direction of movement, so that successive imprints are latitudinally displaced. Slippage may be due in part to differences in thickness of the continuous strip of material constituting the label, or several other causes. In any event, continuous precise registration of successive multicolor superposed imprints is virtually impossible. Very soon, errors in registration of successive imprints occur that make the product commercially unacceptable, and registration must be restored.
SUMMARY OF INVENTION It has been found that there is a method of controlling the movement of a continuous strip of material from one imprint station to another, and yet others besides, that provides absolutely accurate registration continuously. Such a method is embodied in an apparatus wherein each forward movement of DESCRIPTION OF THE DRAWINGS These objects and advantages are shown by way of illustration in the drawings in which:
FIG. 1 is a side elevational view of an apparatus for hot stamping successive imprints in registration;
FIG. 2 is a top plan view thereof;
FIG. 3 is a front elevational view of the clamp; and
FIG. 4 is a side elevational view of the printing head.
DESCRIPTION OF PREFERRED EMBODIMENT Referring now to the drawings in detail, the labelregistration control mechanism assembly provides a mounting for a feed roll 11 and a takeup roll 12. In between the feed and takeup rolls 1], 12, there is an imprint platen 13. Stock or tape 14 to be imprinted is led over a guide roller 15, which is engaged with an idler 10, and then led over the imprint platen l3.
Positioned above the imprint platen 13 is a printing head 5. The printing head is provided with a plurality of dies 16. A separate die is provided for each'of the colors to be imprinted upon the stock 14. The dies are heated. The stock 14 to be imprinted is pulled over the imprint platen 13 by being led between-a driven roller 17 and an idler 18, from between which, it is wrapped around the takeup spool 12. The takeup spool 12 is driven by a chain 19 engagedwith a sprocket on the takeup spool shaft, and engaged with a motor shaft; the motor also drives roller 17. The movement of the stock 14 is interrupted periodically by a clutch 8 connected to the roller 17, which clutch is operated intermittently as hereafter set forth. 2 In order to coordinate the takeup of the stock 14 with the advancement of the stock 14, an air driven clamp 20 is mounted on a-pair of shafts 21,21 for reciprocation. The limit of return movement of the clamp 20 is determined by a fixed stop 22. The distance of advancement of the clamp 20 is determined by a movable stop 23. The movable stop 23 is affirmatively positioned by movable threaded detents 24 mounted on threaded shafts 25,25 By rotating these detents 24,- the movable stop 23 may be adjusted to any chosen position to limit the extent of advance of the clamp 20. The clamp 20 is constructed with a central aperture 26 (see FIG. 3) in which there is mounted a gripper or pressure plate 27. The pressure plate 27 is mounted on a shaft 28 operably connected to a reversible cylinder '29, and is normally held raised from the stock to be imprinted which passes through the slot or aperature 26. The pressure plate 27 may, be moved downwardly by the cylinder 29 to engage the stock 14 and hold it firmly in the clamp 20. Thus, when the clamp 20 grips the stock 14 at the starting position shown in FIG. 2, it will move with the stock 14 a predetermined distance, dependent upon the position of the movable stop 23. At that point of maximum advance, theclamp 20 is released by reverse operation of the cylinder 29, and the stock 14 is then free, but does not continue to move as will be hereafter set forth.
Mounted upon the movable stop 23, there is a first electroswitch 30 and a secondelectroswitch 31. The first electroswitch 30 operates the clutch 8 to disengage the puller roller 17, and at the same time, to energize a brake 9 on the guide roller 15 In this manner, the forward movement of the stock to be imprinted is halted. The second electroswitch' '31 closes the circuit to a control for a cylinder 33. The cylinder 33 moves the printing head 5 downwardly to engage hot dies 16 and the stock 14 to be imprinted.
The heads shows three spools of foil 4 for tricolor imprints. The stock 14 moves eachtime a precise distance to be under each successive die for successive imprints. While I refert hot stamping, other transfer processes may be used.
The heated coating on the foil 32 is transferred to the stock 14 to be imprinted. As the imprint stroke is completed, the printing head 5 engages a third electroswitch 40, which acti'vates the cylinder 33 and restores the head 5 to up position. A fourth electroswitch 41 at the raised position, operates a latch relay (not shown), which engages the clutch 8 to drive the puller roller 17 and simultaneously releases the brake 9 on the guide roller 15. At the same time, the cylinder 29 on'the clamp 20 is actuated so that the stock is seized by the pressure plate 27. The puller roller 17 now being in operation, and the gripper 20 being locked on to the stock 14, the clamp 20 is drawn forward by the stock 14 until it again encounters the r'nieroswitches 30,31 which release the clutch 8 on the puller roller 17, and sets the brake 9 on the feed roller 15.
It will be seen that the gripper has been advanced bythe stock 14 pulling it forward. The released gripper 20 is now returned to initial position against the first stop 22 by a reversible cylinder 35 which retracts the piston 36. When the stock 14 is being fed, the cylinder is reversed and it advances the piston 36 to fully extended position as shown by the dotted lines in FIG. 1. The third switch, which is actuated when the head 5 has descended, also actuates the cylinder 35 to pull back the piston 36. The piston has a head 37 which engages a finger 3'8 on the bottom of the gripper 20, restoring the gripper 20 to the initial position-against the first stop 22.
The imprint platen 13 is adjustable as to height by being mounted on a rotatable threaded shaft 39, which may be locked at any desired height to accommodate vario'us thicknesses of stock 14. The advancement of the gripper from the first fixed stop 22 to contact the second or adjustable stop 23, advances with the stock 14 for each imprint operation, a precise and exact predetermined distance, so that when the second imprint, and subsequently the third imprint, are superimposed on the first imprint, the second and third imprints will be in precise registration with the first imprint and with each other.
It will be seen that the distance of advancement of the imprint strip 14 is, at each step, precisely controlled by the limited movement of the clamp 20. As a result, between imprints, the stock is advanced a precise, predetermined distance for each superposed imprint, and registration is always accurate.
The foregoing description is merely intended to illustrate an embodiment of the invention. The component parts have been shown and described. They each may have substitutes which may perform a substantially similar function; such substitutes may be known as proper substitutes for the said components and may have actually been known or invented before the present invention; these substitutes are contemplated as being within the scope of the appended claims, although they are not specifically cataloged herein.
