WILLIS M. CARTER, OF HOIBOKEN, NEW JERSEY, ASSIGNOR TO THE W. F. POWERS COM- PANY, A CORPORATION OF NEW YORK.
MOUNTING MACHINE.
Application filed July 8,
T all whom it may concern:
Be it known that I, NVILLIs M. CARTER, a and resident of Hoboken, county of Hudson, State of New Jersey, have invented an Improvement in Mounting Machines, of which the following is a specification.
My invention relates to a machine adapted for mounting paper upon pasteboard or a similar material and is particularly useful 11 cases in which it is desirable to secure an exact registry of the paper and the board upon which it is mounted, as for instance in the case of cut-out pasteboard displays in which the outline of the pasteboard may simulate the outline of the figure and the paper mounted upon it is correspondingly colored.
My invention aims to produce a machine of the character described adapted to the handling of sheets of board of varying size and thickness, to which the paste or other adhesive is applied in a uniform manner so as to secure adhesion of the paper throughout the entire-surface without the presence of lumps or bubbles and in which the paper nay be mounted upon both sides of the board simultaneously. It will be understood that colored paper or the like is mounted upon the side of the board to be displayed and that upon the back thereof descriptive matter is mounted, or frequently a sheet of blank paper is pasted in order to prevent buckling or warping of the board.
In general my machine comprises three A portions in which various parts of the operation are performed. 1n the first portion the adhesive is applied and spread, in the second the board is positioned so as to register with the paper which is to be applied and to synchronize its movement with that of the paper, and in the third portion the paper is mounted.
In the drawings I have shown:
In Figure 1, a more or less diagrammatic illustration of the machine of my invention, it being a side view with some of the portions of the machine broken away;
In Figure 2, a detailed view of the mechanism by which the movement of the board is arrested in order to position it;
In Figure 3, a detailed view of a portion of the arresting mechanism;
In Fi res 4 and 5, detailed views showin the mec anism adapted to position the board laterally of the machine, and
1922. Serial N0. 573,707.
Figure 6 illustrates a sectional view of one of the rollers employed with the board positioning means, with its associated chain.
. It will be understood that the machine illustrated is only one form which my invention may take and that it can doubtless be modified to a considerable extent without departing from the spirit of my invention, and that I therefore do not intend to confine myself to the specific form shown.
Referring to Fig. 1, the line of travel of the board is illustrated by the line 1, the board being fed into the machine in sheets at the point 2 and engaged by feed rolls 3, which may be held in contact by means of a spring 4, or otherwise, so as to provide a yielding engagement with the board, but at the same time exert sufiicient pressure thereon to drive the board forward. It will be understood that the lower roll 3 and all other driven parts of the machine are operated from a suitable source of power attached to the shaft 5, motion of which is communicated to the other parts of the machine throu h the shaft 6 and suitable gearing, the details of which it is unnecessary to describe as they are of conventional form and easily available to those skilled in the art.
The board after passing through the feed rolls 3, 3 is fed to the paste rolls 7, '7 which are supplied with paste from the Wells 8, 8 The paste rolls 7, 7 are also held in yielding engagement with the board by means of the spring 9, or in any other suitable manner. The board then passes to the wiping rolls 10, 10, which may be held in yielding engagement with the board by means of a spring 11. These rolls serve to spread the adhesive evenly over the surface of the board, to break up any lumps which may exist, and to force the adhesive into the fibre of the board.
The board is then carried forward over a v carrier comprising a series of rolls 12, which rolls are shown in detail in Figures 5 and- 6, and consist of a plurality of disks 13, having teeth 14 on their peri hery mounted side by side upon transverse afts 15. Rolls 12 are by reason of their construction adapted to drive the board forward through the machine, while at the same time producing no disturbance of the paste upon its surface. They are set at an angle to the transverse line of the machine, as illustrated in Fig. 4, and are driven by means of a chain guide dinal axis of the machine. The rolls 12, mak-.
ing an acute angle with guide 18 carry the board over to contact wit the guide 18 and maintain it in contact therewith throughout its travel, thus positioning the board laterally. The length of the carrier portion of the machine and the number of the rolls 12 included therein may be varied in accordance with the'character of the adhesive used in the machine and the speed at which it is driven, it being desirable to allow a suflicient length of time to elapse between the time that the board leaves the wiping rolls 10 and the time when the paper is applied, to permit the adhesive to become sticky to the {correct degree for the application of the per.
The board having been positioned laterally by means of guide 18, itis desirable to synchronize its movement with the movement of the paper to be applied to it. This is accomplished in the machine of my inven tion by means of the parts which will now be described. Referring to Fig; 2, it will be seen that mounted upon shaft 19 is cam 20 which is driven by shaft 6. and being geared to shaft 5 by means of the gears 21 and 22 hears a fixed relation of movement to the drive of the mounting rolls 23 and 24,
' by means of which the paper is applied, as
will be described hereafter. Mounted iipon the frame 25 of the machine is a guide 26 within which a plunger 27 is adapted to move, the plunger being driven by cam 20 through the cam roller 28. Pivotally mounted upon frame 25, as for instance at 29, is a swinging frame 30, carryin a bracket 31, within which an adjustable abutment ismounted, the abutmentcomprising a threaded shaft 32, having an enlarged .end 33, which for convenience in determining the adjustment may he graduated as shown to cooperate with the pointer 34 and a lockingnut 35. By means of the mechanism just described, the shaft 32 may be screwed up or down in the bracket 31 to any desired adjustment and locked in position by means of locking nut- 35. Plunger 27 cooperates with the enlarged end 33 to raise and lower the swinging frame 30 in response to the curvature o the cam 20. Carried at the outer end of the frame 30 are, the feed rolls 36 mounted upon shaft 37. Feed rolls 36 are preferably in the form of relatively thin disks adapted to engage the edges only of the board. These rolls cooperate with feed rolls 38, which are driven by suitable gearing indicated at 39 and 40 from the shaft 19. The swinging frame 30 and the separation of the rollers 36 and 38 may be given an initial adjustment by means of nuts 41 on shaft 42, which may be turned to force the swinging frame 30 upwr idly against the tension of the spring 43 to accommodate any desired thickness of board between the rolls 36 and 38. The mechanism just described, it will be seen, provides for the movement of the swinging frame 30 in response to the curvature of the cam 20 in a vertical direction against spring- 43, so as to release or grip and feed the board between the rolls 36 and 38. The weight of the swinging frame 30 and the tension of the sprin 43 are ordinarily suflicient to return the ilunger 27 and to hold it in contact with the cam 20; but if desired, additional means, such as the spring 44 may be provided. There may also be provided, if desired, an indicating dial and pointer 45, 46 to indicate the initial adjustment of the position of the swinging frame and feed rolls.
Piyotally mounted upon the swinging frame 30, as for instance by bein attached to the loosely mounted shaft 45, is an arm 46 (see Fig. 3) carrying at its outer end pivot 47, upon which a pivoted finger 48 is mounted. Finger 48 is normally held in position as shown in Fig. 3 by means of :i yielding connection such as the spring 49, and, as will be seen, may be raised and lowered out of the path of the board by the rotation of the shaft 45.
Fixed upon the shaft and mounted oppositely to the arm 46 is an arm 50, through an aperture in the end of which the rod 51 passes. Mounted upon rod 51' is an abutment 52 for the spring 53 which bears upon the under side of arm tending to force it upwardly against the limiting stop 54. The lower end of rod 51 is fixed to a bracket 55 which is attached to the plunger 27 and is permitted to be moved vertically by means of a slot in guide 26.
From the foregoing it will be seen that as the plunger 27 rises, thus raising the swinging frame 30 and separating the feed rolls 36 and 38 as before described, the finger 48 is forced into its downward position (that shown in Fig. 2) by means of the spring 53 acting against the arm 50. During this time the board is driven forward and is positioned by bringing up against finger 4-8. When, however, the plunger falls due to the revolution of cam 20 and the rolls 36 and 38 take hold of and drive the board, finger 48 is raised out of the path of the board by stop 54 being brought into contact with the upper side of arm 50, thus rocking shaft and raising arm 46. Since the feed 'of the board is thus resumed and the obstruction of finger 48 removed from the path of the board in definite timed relation with respect to the rolls 23 and 24. upon which the paper is held, and since the board has been positioned laterally 'due to its engagement ,with the guide 18, a perfect registry of the board and the paper will result.
The paper may conveniently be mounted by means of rolls 23 and 24 driven from shaft 5 by the worm gear 56. The upper roll 24 is preferably mounted in the swing ing frame 57, which may be given an initial adjustment to accord with the thickness of the board to be used, by means of nuts 58, roll24 being downwardly pressed if desired by means of spring 59. Therolls are provided with grippers 60, the details of which are not shown, since any suitable form known to the art ma be used, and which grippers are prefera ly arranged to cast off at or shortly before the paper is brought into contact with the board, the paper being held to the rolls 23 and 24 after the grippers are cast'ofi' by means of a suction device 61.
The paper may be fed from the tables 62 and 63, or in any other suitable manner adapted for the feeding of sheets.
It will be noted from the foregoing description of my improved machine that it is adapted to accommodate widely varied sizes and thicknesses of board and paper, and that its speed of operation varied in accordance with the character of the work in hand and that registry of the board and paper mounted thereon is produced in a positive and accurate manner without undue multiplication of the parts. Provision is also made for initial adjustment and the engagement of the various rolls etc. being flexible, the machine is not subject to damage by accident. I
