This invention relates to improvements in coating machines.
One of the objects of this invention is to produce a coating machine provided with 6 a rotatably supported or mounted coating roller having a plurality of coating surfaces or areas separated and preferably completely isolated by transverse and circum erential non-coating grooves or channels, combined with means adapted to feed sheets or plates of metal or other material to be coated into properregistration with such separated coating areas.
Another object of this invention is to produce a machine embodying a coating roller having coating areas separated by non-coating transverse grooves and means for rotating said roller, and positive feeding means havin the movement of its feeding element synchronized with the movement of the roller to cause proper registration of the plates with the boundaries of the areas comprising the non-coating and separating transverse grooves in the roller.
Another object of the invention is to utilize, incombination with a coating roller, side aligning means adapted to engage the side dges of plates of material to be coated to cause the same to be moved into alignment with the boundaries of the areas defined by the circumferential non-coating and separating grooves in the roller.
Another object of our invention is to produce a machine embodying a rotatablysupported coating roller having a seriesof coating areas bounded by non-coating rectilinear grooves extending transversely and circumferentially, and means for rotating said roller, of plate-feeding means synchronized with the roller-rotating means to cause registration with thenon-coating transverse grooves and side aligning elements to cause registration with the non-coating circumferential grooves.
Another object of this invention is to provide in a machine of the character described having acoating roller provided with a series of separated coating areas, means for facilitating the scraping of the plate-supporting roller or drum, and to this end we preferably utilize a spreading roller for initially spreading the coating material over the uncoated strips on the supportin roller or drum to enable the scraper more e the su coating liquid to prevent the accum ation of material in the pocket or groove formed between the abutting peri homes of the coating roller and the distri uting roller, and
to this end we arrange between the two lines of contact of said distributing roller with ply and coating rollers res ectively an ad itional ueeze-ofi roller which engages said distributing roller and squeezes oif any excess of material before the same reaches the abutting periphery of the coating roller.
Another object of this invention is to rovide improve lever-operated means for rst lowering the supporting roller to se arate the same from the coating roller an then in the same continuous cycle of movement or operation lowering the coating roller to separate the same from the distributing rollers while maintaining separation of the coatin roller from the supporting roller. ith these and other objects in view, the invention comprises the combination of members and arrangement of parts so combined as to co-act and cooperate with each other in the performance of the functions and the acc'omplishmentof the results herein contemplated, and comprises in one of its adaptations the species or preferred form illustrated in the accompanying drawings, in which Fig. 1 is. a vertical section of a coating machine embodying my invention, the section being taken on the line 11 of Fi 2;
Fig. 2 is a cross-section of the mac ine shown in Fig. 1 on the line 2-2 of said Fi 1' 1 Fig. 3 is a fragmentary section on the line 3-3 ofFig. 2 showing the coating and supporting rollers in side elevation;
Fig. 4 1s a fragmentary section through the feeding table on the line 44 of Fig. 2;
Fig. 5 is a fragmentary section on the line 5-5 of Fig. 2 lookin in the direction of the arrow and showing t e coating roller in operative position in contact with the suporting and distributing rollers respectivey; and
Fig. 6 is a view similar to Fig. 5 showin the inoperative position and se aration 0 the coating, supporting and distri uting rollers respectively.
Referring now to these drawings, which illustrate a preferred embodiment of my invention, 1 indicates frame supporting members of conventional form w ich are tied together in any suitable manner. Rotatably mounted in the supporting frame members 1 by means of the usual pairs of slidable bearing blocks 2 and 3 are a coatin roller 4 and a supporting roller 5, the aring blocks 2 being pressed upwardly by springs 2 and adjusted b screws 2".
The frame mem ers 1 are also provided with brackets 1' on which is supported in alignment with the meeting peripheries of the supporting and coating rollers a table top 6 stiffened at its outer'end by means of an angle iron 6" and at its inner end by a strip 6", the table top in the embodiment shown comprising as shown three metal plates and being connected to the bracket by screws 6.
The table top 6 is referably provided intermediate its side e ges with a pair of slots 7 and supported beneath the table in alignment with these slots 7 are a pair of conveyor chains 8 having a pluralit and preferably,'as shown, two pairs of eeding elements 8", which during a part of the travel of the conveyor chains on their upper stretches pro'ect upwardly through the slots 7, the chain ing preferably so mounted and guided that the fingers at the beginning of the feeding movement project u the full distance and toward the end of the eeding movement are lowered out of the slot until finally they extend entirely below the same. As shown, the chains are guided by runnin over supporting channels 8 for ortions 0 'their upper stretches. These c annels guide the chains and maintain the feedin elements in proper position above the ta le top or feed-bed during the major portion of the feedin movement thereof, after which, due to the lower mounting of the inner end of the chain, the feedin elements in passing throu h the slots gra ually disappear below the evel of the table.
In the preferred embodiment of our invention, the periphery of the coating roller 4 is split up by a series of transverse and circumferential ooves into a series of separated and pre erably completely isolated coating areas, so that a sin le metal plate, or other sheet of material ed through the machine, will be provided with a series of coated portions or areas separated or bounded at sides and ends by uncoated mar 'nal strips, the coated areas forming b anks which may be severed from the plates or sheets to provide coated units or blanks having uncoated marginal strips which will enable ready soldering of the margins without scraping. The movement of the conveyor chains 8 and their feedin fingers 8' are preferably synchronized wit the rotation of the coating roller to cause the edges of the sheet to register with the non-coating transverse grooves or channels in the roller.
In order to have the side edges of the plates register with the circumferential channels, it is desirable to provide side aligning elements, and in the preferred form illustrated we provide a pair of springpressed aligning elements 9 mounted upon carrying rods 10-10 slidable in bearings 1 in the bracket 1". These carrying rods -10-10 are connected by rods 11 to opposite ends of a centrally located pivoted rocking, link 12 so that said rods and the aligning elements will be caused to move simultaneously toward and away from each other. Movement is preferably transmitted to said rods and elements by connecting the end of one of the rods with a cam slot 13 in a roller 14. As shown, the end of the rod 10' is connected by a slot and pin connection with an arm 15' of a bell-crank lever 15 pivoted intermediate its ends at 15 on the bracket 1, the other arm 15 of said bell-crank lever being provided with a roller 16 fitted within the cam-groove 13 of the roller 14. Movement may be transmitted to this cam roller in any suitable manner and as shown is rotated, and preferably s nchronized with the movement of the fee ing elements, b
one of a series of gears hereinafter specific Obviously when the cam roller is rotated the bell crank lever will be rocked about its pivotal point 15" and this will cause the simultaneous movement in opposite directions of the rods 10 and 10 carryin the springpressed aligning elements. s illustrated, these elements are mounted upon brackets 9 which are adjustable on the respective carrying rods 10-10. As more particularly illustrated in Fig. 4, each element is mounted upon a pair of pins 9 having springs 9 interposed between the same andthe brackets 9. Obviously when movement is imparted to the cam slot in synchroniza tion with the conveyer chain, as aforesaid, these aligning elements will move inwardly toward each other to engage the plate being fed to the machine and if the same is out of alignment on either side, the element on that side will engage the edge thereof and cause the said plate, as it is finally moved into contact with the coatin and Ill supporting rollers, to assume -a position or tration of the plate or sheet with both the transverse and circumferential grooves in the roller. Thus the front and back edges of the plate will be in registration with one of the transverse grooves in the said roll-- by the grooves in the roller, uncoated margms are formed which facilitate soldering of such edges. In many cases also the sheet fed into the machine contains a series of printed legends or labels and the alignment and feed fingers as above specified will cause such printed legends to come within and register with the separated coating areas on the roller. This is particularly true where the blanks are intended for use in making cans or like containers.
Our distributin apparatus for the coating liquid prefera ly embodies the conventional tank 17 with a supply roller 18 rotatably mounted in contact with the liquid therein, and a distributing roller 19 rotatably mounted in contact with the coating roller 4. These rollers are mounted in con ventipnal manner on a bracket extending from the frame 1 at the upper end thereof, and a roove, crevice or pocket is necessarily former? between the coating roller and the distributing roller. With many forms of coating material an excessive accumulation thereof occurs in the pocket or groove so formed and this results in uneven or rough coating of the plates. In order to prevent this excessive accumulation of material, we
preferabl mount in any suitable manner an ad ditiona roller having its periphery in con tact with the distributing roller at a lane or line between the lines of contact 0 said roller with the coating and supply rollers respectively, so as to squeeze o said di's-' tributing roller, before it reaches said crevice, groove or ocket, any excess of material that would 0t erwise pass to the coating roller and as shown, a squeeze-01f roller 20 is so rotatably mounted in contact with the said distributing roller as to ueeze off any excessive material which may e carried by said roller. By this arrangement we are enabled to more evenly distribute coating on the coating roller and on the plates or sheets of metal or other material coated thereby.
Our improved means for scrapin of the supporting roller will now be descri ed. It comprises the use in combination with a conventional holder 26 for a scraper blade 27 which holder is mounted on the shaft 24 supported on a bracket 3' carried by the bearing blocks 3 of the supporting roller. Said blade 27 is normally held in contact with the periphery of the supporting roller porting roller.
5 by conventional means so as to scrape therefrom coating material which accumulates thereon. In a machine having a roller with the series of isolated or separated areas hereinabovc described, the supporting roller will naturally become coated with a series of isolated areas separated from each other by uncoated strips and we have found that a scraper of the type hereinabove described will not effectively scrape each of such isolated coatings from the periphery of said supporting roller. \Ve have therefore provided means for spreading and connecting the isolated or separated sections or areas to form a single layer or coat which may thereafter be removed in a substantially single sheet or layer by the scraper. For this purpose, we pivot intermediate their ends on shaft 25 also supported in brackets 3*, arms 28 which carry at one end a pressure roller 29 normally forced into contact with the periphery of the supporting roller b screws 30 mounted in a block 30 on a ro 31 and engaging the opposite ends of said arms 28.
-The scraper is likewise forced into contact with the periphery of the roller by providing the holder with outward extensions 27',
which are pressed downwardly by screws 27 mounted in blocks 27 on the rod 31. Our preferred means for se arating the rollers embodies means for owering the supporting roller and its auxiliary scraper and spreading rollers and by the same cycle of operation or movement lowering the coating roller away from the distributing roller while at the same time maintaining a separation between the coating and supporting rollers and also between the latter and its auxiliary scraper and spreading roller, and
to this end we utilize the conventional op-' erating lever 21 fixed on a rock shaft 21 adapted upon movement of the lever to turn the rock arms 22 connected by turnbuckle links 23 to the bearing blocks 3 of the sup- The spreader-roller and scraper bein as aforesaid, mounted on the bearing-bloc '3 will move with said bearing block when the same is lowered through operation of the lever 21 but by reason of the contact of the arms and members 28 and 27 with their respective screws will, upon lowerin of said block, be separated from the peripher of said roller 5. In the preferred embo iment illustrated our means for lowering the coatin roller and se arating the same from the distributing roli er after the supporting roller has been separated from such coating roller, comprises the proend hooks 34" connected to pins 35 on the bearing blocks 2 of the contact roller. The lever 21, in the embodiment shown, has intermediate its ends a slot 21" which contacts with a pin 21 on the frame 1 so as tolimit the movement of said lever 21. Obviously the upward movement of the lever 21 will first cause a lowering of the bearing blocks for the supporting rollers and a continuance of its cycle of movement will thereafter, through the action of the cam 32 on the pedal 33, cause a lowering of the blocks 2 to separate the coating roller from the distributing roller, it being understood that the parts and movements will be so proportioned that the supporting roller will in its lowermost position be still separated from the contact roller when the same is in its lowermost position. \Ve preferably mount at the opposite side of the contact rollers a series of take-off belts 36 which, as shown, are mounted on roller 37 fast on a shaft 38 driven by gears 3838".
In order effectively to drive the various rollers, belts and feed mechanism and to synchronize the movement of the feeding elements with the rollers and also to synchronize the movement of the cam-operated aligning elements with the feeding elements, we preferably provide drive pulleys 39 mounted on a drive shaft 40 having a ear 41 which meshes with a gear 42 mounte on a shaft 43, on which the supporting roller 5 is mounted. Said shaft 43 has fixed thereon at its opposite end a gear 44 which, in the preferred embodiment shown, meshes with an idler 45 on the drive-shaft 40, which meshes with a double toothed idler 46 on the stud shaft 47. This idler gear 46 meshes with a gear 48 on a shaft 49 upon which the coating roller 4 is mounte Said gear 48 meshes with a ear 50 on the shaft 51, on which the distri uting roller 19 is mounted. The gear 50 meshes with the gears 52 on the shaft 53, on which the supply roller 18 is mounted and said gear 50 also meshes with a gear 54 on a shaft 55 on which the squeezeofi roller 20 is mounted. The gear 44 also meshes with a gear 56 which is mounted on the stud shaft 57, on which the cam-drum 14 is mounted, and the gear 56 in turn meshes with pinion 58 onthe shaft 59 which extends beneath the table and has mounted thereon drive sprockets 60 which drive the conveyor chains 8 over sprockets 61 mounted on shaft 62 supported in bearin brackets 62 on the lower surface of the tab e top 6.
