METHOD OF AND APPARATUS FOR INSERTING MARKING STRIPS INTO STACKS 0F SHEETS Filed Sept. 8, 1965 United States Patent Int. Cl. B65h 33/00, 5/08, 29/24 US. Cl. 9393 8 Claims ABSTRACT OF THE DISCLOSURE The invention relates to a method and apparatus for inserting marking strips into sheets or packets of sheets coming from paper or sheet cutting machines and includes the conveying of the cut sheets in overlapped condition along a path of movement, during such conveying momentarily deflecting and lifting the leading edge of a selected sheet out of its path of movement, while so deflected inserting from above a V-shaped marking strip with its free edges facing the line of movement so that the lifted leading edge enters the gap between such free edges, engages the marking strip and carries the same along in continued movement of the strip and after insertion restoring the conveyed cut sheets to their original path of movement. The deflection and upward lifting of the leading edge of a selected sheet is effected at the central region of such sheet while the balance of the sheet is constrained to follow the original line of movement and may be effected by use of a tapered guide, a jet of compressed air directed toward the oncoming sheets, the combination of both of these measures or by using two laterally spaced suction rolls which lift up the central portion of a leading edge to provide a gap to receive a marking strip.
This invention relates to a method of and apparatus for inserting marking strips into stacks of sheets delivered from transverse cutters and similar paper processing machines ejecting sheets.
In this particular field it is known in the case of transverse cutters to insert marking strips in the area of the advance movement of the sheets toward the stack to be produced in such a fashion that following the stacking of the sheets an end portion of the marking strip projects or extends beyond an edge of the stack. The marking strips are inserted automatic-ally following a run of a predetermined number of sheets whereby the complete stack is sub-divided or separated in a readily discernable manner such as by reams. It has been ascertained that the insertion of flat marking strips into stacks is not entirely satisfactory since there is the possibility of such strips shifting their position so that the strips are not visible.
For the above mentioned reason it has become the practice to employ V-shaped marking strips which are grasped by the forward edge of the sheet to be marked while the same is moving forward in the direction of the stack and thereby moved along with the sheet. Such a configuration of the marking strip ensures the proper positioning of the strip and, as a consequence, gives a definite and apparent marking of the number of sheets in the stack. However, by virtue of the high operating speeds employed in such machinery, there is the danger that thin and delicate paper sheets may be damaged by the grasping and carrying along of the V-shaped marking strips.
The deposition of the sheets on the stack at such high operating speeds also presents problems and it has been customary to retard the sheet movement by an increasing overlapping of the same viewed in the direction of the stack thereby assuring a substantially trouble-free deposition of the sheets. To avoid the above referred to damage to the forward edge of the sheet by the V- shaped strip, it has oeen found desirable to move the marking strips into the sheet run when the forward speed thereof has been reduced substantially in proximity to the stack of sheets. In connection with such an operating procedure, it is a prerequisite that means be provided for the angled end of the V-shaped strip to engage properly the forward edge of the overlapped moving sheet which is to be marked.
To overcome these difliculties is a salient object of the present invention and generally comprises the concept of fanning or displacing the forwardly moving overlapped sheets or packs of sheets momentarily upwardly from their normal straight line movement and following the insertion of the marking strip returning the sheets to their initial direction of movement.
By reason of the invention, at the lowered forward speed of the sheets, the marking strip is grasped in the zone of the upward fanning or displacement by the forward edge of the sheet to be marked and after the sheet has been returned to its initial travel path, the strip is held firmly by its angled end by two superimposed sheets. The upward fanning or displacement of the sheets is achieved by the end of the sheet facing the direction of movement being raised from the upper face of the preceding sheet only for a portion of the extent of its Width so that merely an area of the sheet suflicient for the insertion of a marking strip is elevated with the remaining and much larger area of the forward end of the sheet remaining in its initial direction of movement.
In order to eflect the momentary upward fanning or displacement of the sheets there is provided in the zone of the conveying means moving the overlapped sheets or packs of sheets at least one deflecting device which may be mechanical and/ or pneumatic. It has been found advantageous to locate a deflecting device between two conveyor belts or equivalent means which hold down the edges of the sheets or packs of sheets and the deflecting device which is located substantially in the middle of the path of movement of the sheets is defined by at least one guide shoe, preferably wedge-shaped, which extends into the path of movement of the sheets. Moreover, the fanning or displacement in an upward direction of the sheets may be effected by one or more compressed air nozzles located above the path of movement of the sheets and, in the case of certain types of papers which have a tendency to cling or adhere together, it may be advisable to allow a mechanical deflecting means constituted by a guide to cooperate with a compressed air nozzle.
It is further possible to realize the desired deflection of the sheets from their normal path :of movement by the utilization of one or more suction type rollers mounted a short distance above the path of movement of the sheets with the roller or rollers being driven in dependence upon the speed of movement of the sheets.
Additional objects and advantages of the invention will become more readily apparent to those skilled in the art from the following detailed description and annexed drawings, in which drawings:
FIGURE 1 is a diagrammatic view illustrating a preferred embodiment of the invention,
FIGURE 2 is a view taken along the line 2-2 of FIGURE 1, the view looking in the direction of the arrows and being on an enlarged scale,
FIGURE 3 is a fragmentary view partly in elevation and partly in cross section on an enlarged scale illustrating the manner in which the sheet is fanned or displaced upwardly respecting the initial path of movement in the zone of the means for inserting the marking strip, and
FIGURE 4 is a fragmentary view on an enlarged scale of a further embodiment for fanning or displacing the sheet upwardly.
As shown in FIGURE 1, a paper web 1 originating from a supply roll (not shown) is fed or moved forwardly by upper and lower feed rollers 2 to a transverse cutting mechanism 3 which sub-divides the web into individual sheets 4. The sheets 4 are overlapped and their speed of movement is retarded in a known manner by means of the coaction of upper and lower endless conveyor belts 5 and *6 and 7 and 8, respectively. After the overlapped sheets leave the conveyor belts 7 and 8 they are moved by an additional conveyor belt 9 to a stack holder 10.
A marking strip inserting means 11 is located above the path of movement of the sheets at a point between the conveyor belts 7 and 8 and the conveyor 9 and the marking strip to be inserted emanates from a supply roll 12 with the inserting means 11 being such as to cut off the requisite length of strip and fold the same into a substantially V-shape and move the V-shaped strip into proper position. The actuation of the aforementioned inserting operation is effected by means of a counter mechanism 14 which is operably connected to a scanning head 15 and to the inserting means 11. The scanning head 15 is disposed above the path of movement of the sheets 4 intermediate the transverse cutting mechanism 3 and the endless belts 5 and 6. The actuation of the strip inserting means is achieved by the counter 14 which, following a specified number of input impulses of the scanning head 15, initiates an output impulse for the operation of the inserting means 11.
As shown in FIGURES 1 and 2, there is provided in the area of the inserting means 11 between the lower conveyor belts 8 and the conveyor 9 an intermediate member 16 which extends transversely of the belts and which is approximately T-shaped in cross section. The member 16 supports a guide shoe 17 and, as best illustrated in FIGURE 2, the shoe 17 is located in substantially the middle of the path of movement of the sheets 4. The shoe 17 is wedge-shaped and the forward or tapered portion thereof extends over the upper flight of each of the belts 8 and the shoe functions to deflect momentarily the overlapped forwardly moving sheets 4 from their direction of movement upwardly in such a fashion that the forward edge of the sheet is elevated away from the upper face of the preceding sheet. It will be seen that there is thus produced a gap into which is inserted the angled end portion of a marking strip 13 supplied by the inserting means 11 and such strip is grasped or engaged by the front edge of the sheet to be marked and carried along by such sheet.
By virtue of the fact that the shoe 17 is located at the middle of the path of movement of the sheets the upward displacement of the sheet is effected solely in the middle area thereof with the side edges of the sheet being held down by the endless belts 7, as is clearly disclosed in FIGURE 2. By virtue of the aforementioned arrangement, an unnecessary wide upward displacement of the sheet 4 is avoided and a quick removal or closing of the gap produced by such upward displacement is accomplished thus providing the secure positioning of the strip 13.
In the event that thin papers which have a tendency to cling together are being processed, it may be necessary to support the fanning or upward displacement by means of compressed air and such an arrangement is shown in FIGURE 3. More specifically, a compressed air nozzle 18 is located substantially opposite the path of movement of the sheets 4 and the nozzle is located above the path of the sheets immediately to the rear of the guide shoe 17.
FIGURE 4 illustrates still a further embodiment of the invention in which the deflection upwardly of a sheet is achieved by two suction rollers 19 mounted a short distance above the path of movement of the sheets and between which the feeding and inserting of the marking strips 13 is effected. The suction rollers 19 which rotate at the feeding speed of the sheets 4 are provided with a perforated wall which encloses a fixed or stationary ring 21 having a slot 20 therein. The width and location of the slot 20 are so selected that the pressure existing within the rollers 19 only becomes effective in the area or zone of deflection.
The invention is not to be confined to any strict conformity to the showings in the drawings but changes or modifications may be made therein so long as such changes or modifications mark no material departure from the spirit and scope of the appended claims.
