Y. Application May 1936, Serial No. 80,796 3 Claims. (01. 93-93 This invention relates to improvements in a sheet counting mechanism, the object being to eliminate certain parts of a sheet Counter now in'general' use which is shown and described in apatent issued to Joseph P Renz, Feb. 1, 1921 for 'Counter and stacker for Sheet material, No; 1,366,938.
-The improvements of this invention reside in simplifying the mechanism for reducing its cost by'eliminating the costly clutch and its associated parts and in accomplishing the results now desired, by substituting simplified tripping devices and connections for supplying marker sheets at determined intervals, which are carried on suitable belts or otherwise between trainsof counted sheets to be delivered'to alay-boy in superposed positions with the interposed marker "sheets, which are slightly longer than the stack sheets and project slightly from'one side of the 0 counted stacks.
The invention possesses other advantageous features, which will be set forth'at length in the following description where I shall outline in full that form of the invention which I have selected for illustrations in the accompanying drawings; in which:
Fig. l is a side elevation of the improved sheet counter arranged on a sheeting machine;
Fig. 2 is a fragmentary View showing the tripped position ,of parts for forming a slack or loop in a running paper web, after a determined count of stack sheets is made and a marker sheet is to follow in the sheet train;
Fig. 3 is a plan View of a portion of a sheeting machine and my improved sheet counter associated therewith, parts being omitted.
Referring to the drawings in detail, ill indicates a sheeting machine frame provided with appropriate bearings for mounting a pair of respective steel and rubber feed rolls H and 52; a pair of smaller take-out rollers i3 and i l at the opposite side of the frame it and a pair of still smaller take up rollers l5 and i6, and finally vertically aligned respective platen and cutter rolls or drums l1 and 18.
The paper web I9, is drawn from a supply roll 20, and passes under a direction roll 2|, then passes between the pairs of rolls just described and thence outwardly between spaced travelling tapes 22, shown mounted on a pair of rolls 23, in the usual manner. The cutter roll i8 is here shown as provided with a single cutter blade i8a, of a length greater than the width of the web l9, to completely sever the same at every full revolution of said roll I8, thus producing sheets of uniform length during a determined count but immediately thereafter, a bar or roller 24, normally held above the web is, is lowered thereon to form a slack or loop 25, see
Fig. 2. V
The above result is accomplished through the counter mechanism by controlledparts thereof, which mechanism may be described as follows:
A base plate 25 is, fastened by bolts or otherwise to a side frame [9a, of the sheeting machine frame H3, and carries studbolts 2i and 28 on which are rotatably mounted respectively connected sprocket and ratchet wheels 29 and to, and 3|, 32 and traversing the respective sprocket wheels 29, 31, in looped or suspended relation, are downwardly hangingcounting chains 33 and 3d, the former being provided with cams or high links 35, and the latter'in' the present embodiment, being provided'with but one cam or high link 36.
vThe counter frame 26, is formed with a longitudinal extension or arm 3i, provided at itsfree end with a circular bearing 3 8, in which are rotatably mounted a sprocket 39, and a crank disk is, which disk is connected by a pitman or link M, to a slide bar 42, operable through guide pieces 33, fast on the counter frame 26.
Affixed to the slide-bar 12, between the guide pieces i3, is a block 44, which has a lower side. extension 45 formed with apertures to receive bearing pins 46 and ii, on which pawls or dogs 48 and i9 pivot.
In operation, when counting, a power chain 59 riding the sprocket 39 and connected with a similar sprocket St on the shaft of the platen drum or roll ll, constantly operates the crank disk ll), for reciprocating the bar 42, block M and the dogs 48, All, the former dog normally riding dead or inoperative, while the latter turns the ratchet 32, the distance of one tooth at each backward movement of the slide bar, and these step movements of the endless chain 3 5, finally bring around its one high cam or link 35 and draws it upwardly under a roller 52, on one arm of a bell-crank 53, pivoted at 54; and whose other arm supports a roller 55, which rests on a tail piece of the dog 48, to hold it out of contact with its respective ratchet in the running of the count on chain 34, however, when, as just described, the raised cam 36, of chain 34, lifts the bell-crank roller 52, it also causes the bell crank roller 55, to rise away from the tail piece of dog 48, permitting said dog to drop onto its ratchet with the help of a small spring 56, and at the next reciprocation or forward movement of the therewith and pivoted to bar 42, the ratchet 30, will be turned a distance of one sprocket tooth, which will bring one of the high links or cams 35 on chain 33, under and past a roller 51, on an arm 58, fast on a shaft 59, extending backwardly through a bracket 60, to receive in fixed relation the lower end of a vertically extending tripper arm 6| having a nose 62, of hard metal, for operative engagement with an equally hard plunger pin 64 operating in a bore 65, and backed by a spring 66, confined in the lower end of a swing-arm 61, made fast with the hub of an oscillatory arm 68, mounted to rock on a fixed shaft 69, confined in a bearing 10, at the top of a post or standard 1|, secured to the upper edge of the counter frame 26, by bolts or otherwise.
Extending through both side frames of the sheeting machine is a shaft 12 to which is keyed a pair of arms 13, (Fig. 3) Within the side frames between the free ends of which the roller is supported near to and over the web I9; and outside of the sheeting machine frame ill, a similar arm 14 is fixed to said shaft 12, the free ends of the arms 68 and 14 being pivotally connected through a link or bar 15.
For returning the arms 58 and 14 to their normal positions after a tripping operation I may employ springs located at desirable points such as at 16 and 11 respectively.
What I claim is:
1. In combination with a sheeting machine having means for moving a paper web therethrough, a drop bar for forming a loop in said web at intervals; a cross shaft; arms rockable the ends of said drop bar and within the side machine; an outer arm on said shaft; a counter; a post made fast to the counter frame and formed with a bearing at its top; a horizontal shaft fixed in said bearing; a hub formed with a vertical arm and a slanting arm, all rockable on said shaft; a spring pressed plunger dog perable in a bore in the lower end of the vertical arm; an oscillatory arm operable at intervals by a moving part of the counter; an elongated trip arm operated simultaneously with the oscillatory lines of the sheeting,
arm and having a nose engaging the plunger dog, for swinging the said vertical and slanting arms, and a link connecting said slanting arm to the said outsidearm, for operating the drop bar to form a loop in the said paper web at intervals.
2. In combination with a sheeting machine having means for feeding a paper web therethrough; a frame for forming loops in said web at intervals; a counting mechanism; a pair of arms converging to a common swinging center and secured one to the other; a horizontal shaft on which said arms are swingable, one arm normally hanging vertical, while the other arm slants down and outwardly from said center; a link connecting the slanting arm to an extension of said loop forming frame; a spring backed dog slidable in the lower end of the said vertical arm; a horizontal shaft in the counter; a vertical arm on said last named horizontal shaft; a roller on the top of the arm just recited, for contacting a moving part of the counter at intervals; an elongated arm extending upwardly behind the counter and rockable when said roller is contacted for contacting the said slidable dog and tripping the said hanging arm and slanting arm together with its connections to the loop forming frame as and for the purpose described.
3. The combination of a sheeting machine having mounted loops at intervals in a running web of paper; a counter secured to the sheeting machine; said device having an extension and an arm on said extension; a post bearing bolted to the counter; a pair of arms rockable in said bearing; a link for connecting one of said arms to the arm on said extension of connected arms in the counter and mounted to oscillate together; one arm disposed in a position to be tripped by the counter at intervals, while the other arm serves for tripping the lower end of the other of said rockable arms, for operating through said link the loop forming device as described.
