This invention relates to straightening mechanism or joggers for aligning sheets in an orderly pile on a receiving or jogging table as they are delivered from the sheet delivery mechanism of printing presses.
The object of this invention is to provide a jogging attachment of the class described that will be simple in construction, comparatively inexpensive to manufacture and more etficient in use than those which have heretofore been used.
This object is attained by providing a device of the class described in which the jogging members will act alternately on the sides and ends of the sheets instead of simultaneously on all four sides as in the case of joggers heretofore designed. Sheets are usually delivered from the press to the jogging table out of alignment. To align the sheets two processes are necessary. These may be conveniently called straightening and positioning. Straightening consists in putting the edges of the newly delivered sheets parallel with the jogging plates and with the edges of the previously delivered and aligned sheets. Positioning consists inputting the sheets in vertical alignment. The straight ening operation necessarily also involves positioning two sides of the sheet. By our construction the jogging plates on two opposite sides of the sheets close in simultaneously, thus strai htening the sheets. Then the jogging plates in the two opposite sides close in simultaneously, thus positioning the sheets. Thus the alignment is effected in at least two operations. It will be understood that in practice the two operations will not be as distinctas might be expected from the above description since it will sometimes require several operations to com plete the alignment. Experience has shown that by this method the sheets are aligned more quickly and accurately than with previously kn own. oggers in which the four ogging members operate simultaneously, thus combining the straightening and positioning operations. lVith this latter method of operation the jogging members act against each other to a greater extent, and the opposing 1936. Serial No. 470,906.
forces tend to cause the sheets to crumple or curl up at the corners.
It is also a feature of this invention that the ogging members are preferably reciprocated several times for each operation of the sheet delivering mechanism.
The jogging arms are operated by a motor or other source of power which drives a bevel gear which is keyed to a shaft on which is mounted a tooth gear which meshes with four gear wheels to each of which is secured a crank pin. Pivotally connected to each crank pin is a connecting rod, which in turn is pivotally connected to a jogging member which reciprocates in slots in the jogging table. The cranks are so arranged relative to one another that two opposite jogging members move together simultaneously and alternately with the other two opposite jogging members, but the cranks could be arranged so that all the ogging members would move simultaneously.
The invention is hereinafter mrre particularly illustrated and described in the anneXed drawing in which Fig. 1 is a plan view of the jogging table;
Fig. 2 a vertical section on the line 22 in Fig. 1; and
Fig. 3 a plan view of the operating mechanism with the top of the jogging table removed.
In the drawing like numerals of reference indicate corresponding parts in the different figures.
1 represents a rectangular receiving or j ogging table which is adapted to receive printed sheets from the sheet delivering mechanism of a printing press. This sheet delivering mechanism is of well-known construction, comprising a bar having a series of fingers secured thereto and extending therefrom at right angles, these fingers being adapted to pick the sheets off the printing press roll and deposit them on the receiving table in a known manner. The fingers are numbered 2 in Fig. 2.
The fingers 2 do not deposit the sheets on the receiving table 1 in an orderly pile, and in order to align these sheets aligning or jogging members 3 are provided. These jogging members 3 are composed of a plate 4 slidable on the table 1 and having perpendicular faces 5 which are parallel to the sides of the table 1. It follows that the faces 3 of opposite jogging members are also parallel to one another and that the faces of adjacent jogging members are at right angles to one another. At the rear of each jogging or aligning member 3 is a downwardly extending lug 6 to which is secured a pin 7. Pivotally connected to said pin 7 and retained thereon by means-of a nut 8, is a connecting rod 9 which serves to reciprocate the aligning member 3 in a manner hereinafter described.
' A slot 10 is provided in the surface of the table 1 in which the lug 6 is adapted to reciprocate. At each end of each aligning member is a guide member 11 which is adapted to reciprocate in a slot 12 in the table 1. These guide members serve to retain the aligning members in their proper position relative to the table and one another.
Secured to a bracket 13 on the under side of the table 1 is a motor 14 provided on its shaft with a crown pinion 15 which meshes with a cam gear 16. The crown gear 16 is keyed to a shaft 17 and retained thereon by means of a nut 18. The shaft 17 is rotatably mounted in a supporting member 19 which is secured to the table 1 by means of bolts 20. The table itself is supported at one end in a manner not shown to the press and at its forward end is supported by legs 21, 21.
- Keyed to the shaft 17 at its upper end is a toothed drive gear 22 which meshes with four driven gears. Secured to each of these driven gears is a crank pin to which is pivoted the connecting rod 9. This connecting rod 9 is made adjustable in length by means of a slot and bolt connection 25. A-nut 26 on the upper end of the shaft 17 serves to retain the shaft and gear wheels mounted thereon in assembly. Suitable bushings or bearings are provided for the various moving parts.
The speed of the motor 1st and the arrangement of the gearing is preferably such as to cause the aligning members to reciprocate a number of times for each operation of the sheet delivering mechanism, so that one batch of sheets is fully aligned before the next batch is delivered. Y
The driven gears 23 are so adjusted relative to each other and to the drive gear 22 that when the crank pin, and the aligning member connected therewith, on two opposite sides are at their outermost position, the crank pin, and the aligning member, on the other two opposite sides are attheir innermost position, so that when the gears are put in motion opposite aligning members will move inwardly and outwardly simultaneously, while adjacent aligning members will move inwardly and outwardly alternately.
I11 other words, two opposite aligning members will be moving in at the same time as the other two opposite members are moving out, and vice versa. As explained in the preamble, this action is much more effective than the usual method whereby all the aligning members move in and out simultaneously. In Fig. 1, a sheet 27 has been shown in its aligned position.
It will be understood that there may be many modifications of this invention without departing from the spirit thereof. For instance, there may on each side of the aligning table be a plurality of aligning members instead of one as shown and described. Instead of the specific method of operating the jogging members shown and claimed, a' cam arrangement or a reciprocating crank may be used.
WVhile a construction might be used in which only two or three adjacent jo ging members may reciprocate, the others being stationary, or being dispensed with, much more satisfactory results can be obtained by the use of four joggers as described above, since with the four moving j oggers the sheets are less likely to fall on top of a jogging member, and the aligning is effected more rapidly and with less movement of each member.
It will also be seen that the construction shown may be readily adapted so that it will operate to reciprocate the aligning members simultaneously as is commonly done.
