7 Claims. (Cl 15-77) The present improvements, relating as indicated to sheet brushing methods and apparatus, have more particular regard to the cleaning, polishing, or otherwise processing of the surfaces of individual sheets, either metallic or non-metallic.
The use of rotary or cylindrical brushes for such general purpose is of course well known, especially where the operation is performed or controlled by hand. However, in attempting thus to clean, polish, or otherwise process the surfaces of a succession of sheets by mechanical means, i. e. means in which the operation is carried out more or less automatically, the serious difficulty is encountered that the rotating brush or equivalent member. depending uoon its direction of rotation, will pick up or injure either the advance edge of the sheet or the trailing edge, Indeed, the foregoing difliculty will arise in attempting to brush a single discontinuous sheet by passing the same between a suitable support and a brush rotating about an axis fixed in relation to such support.
Heretofore attempts have been made to solve the problem of holding down the trailing edge of a sheet so that it would not catch in a brush thus applied thereto by the u e of electromagnets or vacuum holding devices. However, such equipment is not only expensive to install, but by no means certain and uniform in operation. Furthermore, neither such electro magnetic nor vacuum holding means are adaptable for use in conjunction with a continuous type of sheet feed.
One principal object of the present invention is to overcome the foregoing difficulty. Another object is to provide a simple and compact mechanism for brushing a succession of individual sheets whereby the operation may be carried on practically automatically. A further object is to provide in such an apparatus means for applying the brush to the work under predetermined equable pressure so as to insure uniformity in the resulting treatment.
To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims, the annexed drawing and the following description setting forth in detail certain means and one mode of carrying out theinvention, such disclosed means and mode illustrating, however, but one of various ways in which the principle of the invention may be used.
In said annexed drawing:
Fig. 1 is a front elevation illustrating one form of apparatus embodying the present improved 2 features of construction and adapted to carry out such improved method of sheet treatment;
Fig. 2 is a side elevation of the same.
Fig. 3 is a horizontal sectional view taken on line 3-3 on Fig. 2; and
Fig. 4 is a diagrammatic layout of the actuating means.
Certain elements of the mechanism thus illustrated in the drawing, and particularly in Fig. 2, are diagrammatically shown since such elements are familiar in sheet handling apparatus. Thus the individual sheets S, of which only one is shown in the figures of the drawing, are designed to be fed in the direction indicated by the arrow applied thereto in Fig. 2 by means of a series of pairs of opposed power driven rolls I, I, 2, 2 and 3. 3. It has been deemed unnecessary to illustrate the manner in which such rolls are thus driven or to illustrate the supporting and driving means for two larger backing rolls 4 and 5 which are designed to further support the sheet during the brushing operation, as will be presently described.
Located at an intermediate point in the path of travel of the sheet S as it is moved forwardly by the pairs of gripping rolls and preferably al gned with rolls 2, 2, constituting the intermediate of such pairs, is a frame of general rectangular form from which such brushing mechanism is supported, such frame comprising vertical side members 6, 6 and a transverse member 'I as shown in Fig. 1. Oscillatorily supported in such main frame on trunnion bearings 8, 8 in the side members thereof is a secondary frame 9 which carries two similar rotary cylindrical brushes B and B, the shafts b and b of which are journalled in pillow blocks I0 on the respective transverse sides of said oscillatory frame 9. The relation of the axis provided by trunnions 8, the diameter of the brushes B and B' and the path of travel of sheet S is such that when said oscillatory frame 9 occupies a horizontal position or a position parallel with such path of sheet travel neither brush will contact with the surface of the sheet. However, upon oscillating the frame in a counterclockwise direction, as viewed in Fig. 2, brush B will be brought into contact with such sheet face, while upon oscillation in a clockwise direction said brush will be raised out of contact and brush 13' instead will be brought into contact with the sheet surface.
For the purpose of oscillating frame Sin order thus to control the position of the brushes and their contact with the sheet which is to be treated, a double acting fluid pressure cylinder I2 is proassasae vided, such cylinder being oscillatorily supported at its upper end from a bracket It on cross membar 5 of the main frame and the piston rod it which projects from the lower end of the cylinder I? being pivotally connected with an arm 95 that projects from the corresponding side of the oscillatory structure including frame members 9. Such structure comprises an upper plate 26 to which two opposed Channel members 2? and 28 are welded (see Fig. 4). The lower end portions of such channel members are welded to members 9 forming a box-like structure oscillatable about trunnions d. The manner in which such fluid pressure cylinder may be actuated is illustrated in Fig. 4 and described below. However, use of an air cylinder is not recommended because it cannot be satisfactorily controlled for adjusting brushing pressure and the preferred type of device, if air is available, is a so-called airdraulic" cylinder which provides hydraulic control with air power. As indicated, the device should be of a type which will be capable not merely of producing the desired oscillatory movement of frame 9 and of the brushes carried thereby, but of providing desired brush-to-work pressure.
Operation of the actuator which such cylinder 92 with its connections constitutes may be controlled by either a photoelectric cell or a sensitive switch such as a micro-switch, so that the movement of the sheet through the machine will automatically control the position of the brushes B and B. I
Referring more particularly to Fig. 4 of the drawing, the actuating mechanism there illustrated is adapted to operate as follows. A sheet is introduced between drive rolls 33, which may be provided with a slipping clutch, and such sheet advances until it is stopped by roller-footed gate 32 which will be down if, and as long as, a sheet is in process and has not passed roll 3, or if control circuit starting switch 34 is open. Starting switch 34 being closed and no sheet being between rolls 13, valve 30 will be shifted to admit fluid pressure to the lower end of cylinder 3|. lifting gate 32. Simultaneously valve 29 isfshifted to admit fluid pressure into the lower. end of cylinder l2 and thereby rock the brush supporting frame to bring brush B in work contacting position and elevating brush B. Sheet S advances between rolls I and engages-brush B which is rotating in the same direction as the movement of the sheet. The passage of the sheet between rolls I actuates limit switch Hi to reverse valve 30 causing cylinder 3| to permit roller footed gate 82 to drop and rest upon the upper surface of the sheet. When the leading edge of the sheet passes betweenrolls 3 the normally open limit switch I! is closed, causing valye 29 to admit fluid pressure to the upper end of cylinder l2 and thereby moving brush B into engagement with the sheet rather than brush B. Switch I1 is a double switch, one normally open, one normally closed. When the normally open switch is closed as above the normally closed switch is deenergized. When the tail end of the sheet It will be noted that as indicated by the direction arrows adjacent the respective brushes in Fig. 2, the brush B which is thus first encountered by a sheet as it is fed through the machine is designed to be rotated in a counterclockwise direction. i. e. so that the portion of its face which contacts with the sheet will move in the same direction as the sheet is moving. On the other hand, the other. brush B is designed to be rotated in a clockwise direction so that the portion of its face which contacts with the sheet will move in the opposite direction to that of the sheet travel. Any suitable means may be provided for thus rotating the respective brushes.
As shown in Figs. 1 and 2, a motor may be mounted on the upper surface of plate 26, gear 23 on the motor spindle meshing with gears 22 and 35 carried by upstanding bracket 36. Gear 35 is meshed with a gear 2| also carried by bracket 36. Rotation of such gear 2| serves to turn drive pulley 31 which drives brush B through belts 2t and pulley 38. Rotation of gear 22 turns drive pulley 39 which drives brush B through belts 25 and pulley 40. It will thus be seen that the two brushes are driven in opposite directions. Since the direction of rotation of the brush is the same as that in which the sheet is moving, there will be no tendency for the part of the brush to raise or damage the forward edge of the sheet, however thin the latter may be, but on the contrary the tendency will be to smooth out such edge. The essential thing is that the sheet should progress through the machineat a uniform rate of speed which is not in excess of the speed of the actuator; that is the sheet should not advance from the point where the first brush stops brushing to the point where the second brush is brought into operative engagement therewith faster than the time interval necessary to raise and lower the brushes by the actuator. Treatment of the entire surface of the sheet by one brush or the other is thus ensured. Furthermore, since the first brush is raised from engagement with the sheet before the trailing end of the latter reaches such brush, the latter will have no tendency to raise or damage such edge, while the second brush, which remains in contact until the final passage of the sheet through the machine, due to the fact that it is rotating in a direction opposite to that of the sheet travel, will likewise have no such tendency, but on the contrary assist in holding down and smoothing out such edge.
While in the foregoing description of the construction and operation of the machine particular reference has been made to the use of brushes as the surface treating means, it will be understood that the principle of the invention is equally adaptable for use with any type of rotary surface treating member such as abrading rolls, buffers, and the like. In other words, the machine may be used by proper selection of such rotary members to clean, polish, or otherwise treat the surface of individual sheets, and as previously stated,
the sheets thus treated may be of any material passes between rolls 3 such normally closed switch will be reenergized to shift valve to raise gate 32 to admit a new sheet. The normally open switch is now deenergized. Simultaneously with the shifting of valve'30 valve 29 is also shifted, causing brush B to be moved into work engaging position. The described cycle will now be repeated.
