Definitions

  • Patented @et 31, 192 Patented @et 31, 192.
  • Our invention relates to improvements in coating machines, and is particularly directed to an improved construction for readily cleaning parts of the machine which carrythe coating material.
  • Our invention is primarily designed for application to the type of coating machine in which the fluid coating material is transferred from a reservoir by means of contacting rollers to one side of the coated article, which passes over a roller.
  • the applying roller is provided with a number of circumferential giooves to accommodate stripper fingers which break the engagement between the sheet being coated
  • these Grooves and the stripping mechanism as well as other parts of thecoating apparatus to a lesser extent, gradually become more or less gummed up with the adhesive employed for coating.
  • the cleaning which is necessary at regular intervals is more or less tedious and time-consuming, owing to the difliculty in gaining access to all the various corners and recesses of the parts. ⁇
  • a principal object of our invention is to provide means for readily and rapidly cleaning coating apparatus by means which is in part automatic, avoiding the necessity for manual cleaning of the various parts.
  • a further object is to provide means of this sort which will perform its function in a comparatively short space of time, reducing stoppage of the machine for this purpose to a minimum, and which alsomay be conveniently manipulated.
  • our invention is applicable to the type of coating machine in which the coating fluid is heated by a water bath, as is the general practice in gluing machines; and a more specific o bject 1s to employ the water used for'heating the 1921.
  • a concomitant object is to provide a construction in which the heating water may be readily and rapidly applied to the parts to be cleaned.
  • Figure 1 is a side elevation of coating apparatus embodying our invention in coating position, the cleaning position being indicated in dotted lines, parts being 'broken away, and
  • Figure 2 is a similar View with the parts in position intermediate the coating and cleaning positions, the latter position being indicated in dotted lines.
  • a pan for adhesive movably mounted on a trough carrying the hot water bath.
  • the pan and trough are lowered away from the coating rollers, the pan is retracted to expose the water bath, and the trough containing tlie water is then elevated to bring the lowermost coating roller into the bath. 'I he machine is then operated, carrying the hot water over the parts to be cleaned.
  • the coating material 10 such as paste or glue
  • the coating roller 13 in contact with dipping roller 12 receives the coating fluid from the latter and transfers it to the article to be coated, such as a sheet of paper 14.
  • the coating roller 13 is provided with circumferential grooves 15 into which the stripping and cleaning fingers 16 extend, the upper ends of the fingers stripping the paper from roll 13, while the lower ends of the fingers extend into the grooves to clean them, all as set forth in Patent No. 1,331,463. It will of course be appreciated that these details of construction are purely illustrative, as our invention is equally applicable to a great variety of coating machine constructions employing coating rollers or analogous elements.
  • rIhe fluid 10 is maintained at a proper temperature by means of a suitable water jacket heated in any desired way.
  • the hot water 17 in the form illustrated is retained in a trough 18 upon which pan 11 rests, the pan dfpping into the water 17.
  • the water may be heated by steam passing through the pipe coil 19 in trough 18.
  • Pan v11 is slidably mounted on trough 18, so that it may be slid rearwardly to a point where it is completely out of register with the dipping roll 12. This may be conveniently accomplished by providing trough 18 with a flat edge 20 upon which the marl ginal lip 21 of the pan 11 rests, forming a tight connection but permitting the pan to slide along the trough.
  • pan 11 substantially shorter than trough 18, and provide the pan with an extension or hood 22 overlying the front of the trough and having a marginal lip 23 in continuation of lip 21 on the pan llresting on edge 20 of the trough.
  • a filling opening 24 for replenishing the water 17 may be provided in hood 22.
  • handles 25 pivotally mounted at 26 on the hood 22, the handles dropping out of the way against stops 27 on lip 23 when not in use.
  • a handle 25 is preferably mounted at each side.
  • handles 25 swing upwardly against abutments 28 projecting at each side of hood 22 as illustrated in Figure 2, so that the operator may readily lift the' rear end of the pan and slide it forward free from excessive frictional engagement with the trough.
  • cranks 29 pivotally mounted at 30 on bracket 31 of the machine frame, theI upper arms of the cranks being pivoted in clevises 32 on trough 18.
  • the lower ends of the cranks are connected by links 33, so that the trough 18 and pan 11 will maintain a substantially horizontal position while being lowered and raised.
  • a latch including a dog 35 pivotally mounted on lever 34 and normally pressed by spring 36 into engagement with a notch 37 carried by extension 38 of the bracket 31.
  • a thumb piece 39 on dog 35 provides convenient means for releasing the latch when the pan and trough are to be lowered.
  • our invention is not limited to the particular method of lowering and raising the trough and pan, nor to the particular construction and arrangement for retracting the an preparatory to the cleaning operation. s a matter of fact, in the broad aspect of our invention, it is not necessarily limited to a water jacket pan, nor to the employment of the heated water from such jacket in the cleaning operation.
