This invention relates to an apparatus and method for applyingpaste andmore particularly, to a positive feed arrangement forapplyingpa'ste to moving work.
The object of the invention is to provide an applicator for dispensing paste neatly and consistently to work moving therepast. 'While the device has general utility for applying paste, glue, other semi-liquids, it isespeci'ally intended-for and envelope-making machines in which, traditionally, paste was picked up and supplied to an applicator segmentby a roller partiall immersed in an open pot. Inaddition to the inherent messiness of the open paste-'pot,"there were other disadvantages resulting from the lack of positive control over thepaste supplied to the pot. The supply of paste was necessarily closely correlated to its consumption lest the pot underfeed or overflow and, in addition, leakage occurred around the doctor which wipesthe'surface of the roller it leaves the'pot.
lhe object now is to provide anapplicator in the nature of a nozzle having a mouth virtually closed by a paste receiving roller, the paste at all times being supplied under-pressure to the nozzle so to be forced against that portion of the roller surface momentarily embraced by the nozzle mouth. It is also intended to provide the nozzle mouth, at the trailing edge where the roller leaves, with an adjustable lipwipin'g against or near the roller to serve as a doctor 'a'n'd'also to cooperate with the nozzle structure'to form a leak-proof seal. The leading, or roller-entering edge of the nozzle mouth is'to be definedby a. fixed lip or weir spacedradiallyfro'm the roller surface to allow controlled leakage of surplus paste from the nozzle in a-direction counter tothe rotational direction of the roller. The surplus paste is then to be returned to the source'o'f supply by a conveyor operating at a capacity 'farin excess of the supply of pasteto the nozzle so that loss of the overflow to the exterior is impossible.
in accordance with the method concepts, the object of the invention is to deposit a layer of sticky material on a moving surface'by feeding an excess of the material under pressure to a confined space bounded on one side by the moving surface while exhausting the excess through a restricted outlet to an open receptacle, and then to convey on" the excess from the receptacle at a rate potentially greater than the rate of feed to the confined space.
More specific objectives include the provision of an adjustable doctor along one edge of an applicator nozzle wherein the doctor not only serves-asa nozzle edge, 7 withthe associated nozzle structure throughout orlip, but also cooperates all adjust-ed positions of the doctor, and even during its adjustment, to confine liquids or semiliquids within the nozzle. In other words the construction is such that notwithstanding the maintenance of pressure within the nozzle mouth, or-c'haniber, no leakage occurs around the doctor except the intended amount which passes as a film between the doctor and the roll disposed across the nozzle mouth. As a further feature,
the invention provides a manually operable control member extending externally of the nozzle made as come within the scope of the claims.
The accompanying drawing illustrates one complete example of the physical embodiment of the invention constructed according to the best mode so far devised for the practical application or" theprinciplesthereof, and in which:
Figure l is a vertical cross sectional view through the applicator taken along the plane of the line i-i in Figure 2, looking in the direction of the arrows, but showing the applicator roller, transfer roller and a portion of the work drum in end elevation; I Figure 2 is a front elevational View of the applicator, withparts-broken away and in section; and
Figure? is a rear elevational view of the applicator, partially broken away to show the doctor, nozzle and inlet in section.
Referring now to the drawing, in which like reference numerals denote similar elements, the new applicator 2 is shown as it would be seen in a typical environment, such as a bag machine, wherein paste is fed to an applicator segment i of a rotating transfer roller t. Paste or glue, hereinafter generically termed adhesive is intermittentlyapplied by segment l to bags being made as'they passbetween transfer roller 6 and a drum i3. Only the pertinent portions of the bag machine are diagrammatically shown. The applicator roller it, which is a part of the invention, was heretofore conventionally immersed in an open pot.
In this invention, theroller i8 is partially confined within a body illi'igidly supported. Withthe applicator roller iii in rolling engagement with the transfer roller 6. Shaft l4, on which the applicator roller is fixed, rotates in bearings 16 in the ends I8, 20 of the body [2, the shaft 14 being driven in any suitable manner so that whenever the work passes over the drum 8, the shaft [4 turns the roller ID in the direction indicated by the curved arrow in Figure 1.
The lower, inner surfaces of the end walls I8, 20 are in close wiping engagement with the flat ends 22 of the roller lil so as to militate against leakage from a chamber 24 (upwardly disposed) in the body I2, it being apparent that the cylindrical wall of roller 10 constitutes a moving boundary surface for the chamber 24 and that the chamber is in effect a nozzle. Further assurance against leakage from the chamber 24 is provided by an inwardly stepped formation on the end walls l8 and 20, the top surfaces 25 of which partially embrace the ends of the roller Ill with a close running fit.
Adhesive is pumped under pressure from a suitable source, not shown, via an inlet tube 23 and a fitting 28 to an inlet manifold passage 30, whence it passes through metering ports 32 into chamber 24.
The trailing side of chamber 24, as determined by the rotational direction of the applicator roller I0, is substantially closed by a generally cylindrical doctor 34 seated snugly but rotatably in an arcuate recess in the body 12. The doctor has a lengthwise cut-out 3B defining a blade or edge 38 which may be adjusted towards and away from the roller It by rocking a shaft 40, on which the doctor 34 is splined, about its axis. While the shaft 48 is rotatably supported at each end of the body l2 by pillow blocks 42, it is normally held against rotation by a lock nut 44 on its threaded exterior end 46, adjustment of the blade 38 being accomplished by applying a wrench to the square end 48 of the shaft after the lock nut 44 has been temporarily loosened. The pillow blocks 42 also snugly bear against the ends of the doctor 34 to prevent leakage around the ends of the doctor.
The leading side of the chamber 24, (again with reference to the direction of rotation of the roller I0) is partially closed by a weir 50 the free edge of which is slightly spaced from the cylindrical surface of the roller It. The slight space between the weir 50 and the roller l0 provides a restricted outlet for the excess adhesive pumped into the chamber 24 and not carried off by the roller.
Exteriorly of the weir 59 there is formed in body l2 an open trough 52 having at one end a nipple connection 54 for a surplus adhesive outlet conduit 56 leading back to the source of supply for the adhesive A screw conveyor 58 is rotatably mounted in the trough 52 with one end free and fitting in the nipple 54. Its other end has a shaft projecting therefrom rotatably supported by a bearing 62 in the body 12, and driven by gears 64 and 66, splined on shafts and [4 so that whenever the roller I0 is driven in the direction of the curved arrow of Figure l, the screw conveyor 58 turns to carry the adhesive which enters the trough 52 out through the outlet 56. The capacity of the screw conveyor 58, during normal operation of the device, is such that it can remove excess adhesive from the trough 52 at a rate greater than that at which the adhesive enters the chamber 24 through the metering ports 32. It is, therefore, impossible for the adhesive to overflow the trough 52. A clean-out plug 68 for the bottom of inlet manifold passage 3E] and 4 hold-down bolts 10 for the pillow blocks 42 complete the assembly.
In operation, the machine to which the applicator 2 is an adjunct is started, the pump for forcing adhesive through inlet 26 is started, and, along with shaft I4, the applicator roller I0 and screw conveyor rotate. After a brief interval, enough adhesive enters to fill the chamber 24 via the inlet manifold 30 and metering ports 32. When chamber 24- fills, the adhesive is forced against roller I3 and a thin film is carried off on the roller surface for transfer to the segment 4. The thickness of the adhesive film on the roller 10 may be varied by turning the doctor 34 so as to move its blade 33 inwardly towards or outwardly from the roller in, there being no leakage around the underside or ends of the doctor, even during rotational adjustment, because of the leak-proof seals between it and the body l2.
Upon further accumulation of adhesive in chamber 24 resulting from the flow through metering ports 32 exceeding the amount carried off as a film on the applicator roller I0 for transfer to the segment 4, the excess flows over the weir 56 into trough 52 from which it is returned to the source of supply by the screw conveyor 58 and the surplus outlet 56. The flow of excess adhesive over weir 50 is counter to the turning direction of the roller I0. Pressure is thereby retained in the chamber 24 and squirting leakage is prevented not only by the restricted size of the space between weir 50 and the roller l0, but also to some further extent by the tractive counterforce of the moving roller surface.
From the foregoing description taken in connection with the accompanying drawing and claims, it will be readily apparent that this invention provides a particularly neat and frugal applicator and method of applying adhesive in which the adhesive is positively controlled at all times and by which a film of the adhesive is applied under pressure to the moving surface of the applicator roller.
