Application August 27, 1951, Serial No. 243,864

8 Claims. (Cl. 271-89) This invention relates to a jogging machine for straightening sheets in a stack with the edges thereof in registry with each other and more particularly to such a machine wherein the table is lowered and tilted and is elevated and levelled for facilitating application and removal of stacks of paper therefrom.

In jogging stacks of large sheets of paper, the weight and size of the table and the paper thereon make it desirable to have the table at a low elevation, but after the paper is jogged it is usually further processed on trimmers and other equipment having a relatively high feed table, for example a height of approximately thirty-nine inches. While stacks of paper may be jogged satisfactorily on machines such as disclosed in the Daneke Patent No. 2,277,511, issued March 24, 1942, the diiiiculties involved in moving the stack of paper from the jogging machine table to other places of use are such that the jogged stacks are frequently disarranged. Also, stacks of large sheets of paper are heavy and it is often necessary for two persons to lift and move the stack of jogged paper.

The objects of the present invention are to provide a jogging machine with a vibratory table mounted on a supporting frame or structure with means for raising and lowering the table in such a manner as to eliminate the above mentioned difficulties of handling the paper; to provide a jogging machine including a vibratory table and supporting structure therefor which lowers and tilts the table during jogging operations and then raises and levels the table at a suitable elevation for movement of the jogged stack of paper onto a feed table or the like of other paper processing equipment; to provide a jogging machine structure with a vibratory table arranged with a low center of gravity during jogging operations for silent operation and reduction in objectionable transmission of vibration to the building in which the machine is held; to provide such a jogging machine wherein the table is adjustable and movable to facilitate the handling and moving of the stacks of paper; to provide edge guides or fences on the vibratory table for engaging the edges of the sheets to be jogged, said guide fences being movable to clear the side of the table for facilitating removal of the stack of paper therefrom; to provide a jogging table with mechanism for raising and lowering the table and levelling the table in response to the raising movement thereof and tilting the table in response to lowering movement thereof; and to provide a jogging machine of this character which is easy to operate and efficient in bringing the edges of sheets into precise registry and facilitates removal of the jogged stacks of paper without disarrangement of same.

In accomplishing these and other objects of the present invention, I have provided improved details of structure, the preferred form of which is illustrated in the accompanying drawings, wherein:

Referring more in detail to the drawings:

1 designates a jogging machine constructed in accordance with the present invention and which includes a relatively rigid base 2 of suitable size to provide a stable support for the machine. The base 2 includes a heavy plate-like member 3 on the bottom of which is mounted a plurality of spaced casters 4 for facilitating movement of the machine over a floor or other support, said casters maintaining the plate-like member 3 in spaced relation to the floor. In the illustrated structure there are three casters and foot or brake members 5 are mounted on the under side of the plate-like member 3 between selected casters. The foot members are movable vertically relative to the plate-like member 3 by means of levers 6 and when the foot members are extended downwardly they engage the fioor to slightly lift one side of the base whereby the jogging machine is supported on two casters and two foot members. When the lever 6 is operated to raise the foot members the machine is supported only on the casters and is free to be rolled from one location to another.

Telescoping posts or elevator means including lower or sleeve members 7 are suitably fixed on the plate-like member 3 in spaced relation and extend upwardly therefrom whereby the bores 8 of the sleeve members act as guides for upper members or posts slidably mounted in said bores. In the illustrated structure, each of the sleeve members 7 has annular flanges It on the lower end thereof which rest on the upper face of the plate-like member 3. Flanged bearing members 11 are arranged on the underneath side of the plate-like member 3 in alignment with the respective sleeve members and boits 12 extend through aligned

apertures

13, 14 and 15 in the sieeve member flange, plate-like member and bearing member flange respectively.

Each of the posts 9 has long threaded bores 16 into which are threaded long screws 17, arranged coaxially of the sleeve members 7. The lower ends of the screws are provided with collars 18 which rest on thrust bearings 19 in the bores 3 and engage with the upper face of the plate-like member 3. Shanks 20 on the screws 17 extend downwardly through an aperture 21 in the plate member 3 and are rotatably mounted in the bearing members 11, sprockets 22 being fixed on the lower ends of the shanks 29 and operatively engaged with drive members, such as chains 23, which operate over sprockets 2 fixed on a motor shaft 25 of a motor 26 supported on a bracket 27 which is suitably secured to the plate member 3.

The motor 26 is of reversible type whereby operation in one direction turns the screws 17 to effect elevation or upward extension of the posts 9, and operation of the motor in the other direction effects telescoping or downward movement of the posts 9. The upper ends of the posts 9 are preferably flattened and provided with bores 28 through which extend trunnions 29 of a frame or subtable 3%.. The frame 39 is preferably of thick cast metal and of substantially rectangular form to provide a substantially rigid construction, free from any flexure incidental to vibration of the jogging table 31. The opposite sides of the frame are provided, substantially on the longitudinal median line thereof, with internally threaded sockets 32 which register with the bores 28 in the flat ends of the posts 9 to receive threaded shanks 33 of shouldered screws which form the trunnions 29. The shouldered screws preferably have heads 34 which engage the outer faces of the posts and hold same in engagement with the side edges of the frame, whereby the frame may rock relative to the posts but does not have lateral movement relative thereto.

The jogging table 3.2 includes a rectangular frame 35 having side bars 36 connected by end bars 37 and spaced 1 intermediate,

diagonal bars

33 and 39. The bar 33 is adjacent to and on one side of a median diagonal line of the table and the bar 2? on the opposite side of said median diagonal and substantially midway between the diagonal line and the adjacent corner of the frame. upper faces of the

bars

36, 37, 38 and 39 are coplanar. The

bars

36 and 37 are preferably in the form of angles with the legs 41 thereof forming 21 depending peripheral flange for the frame 35. Arranged under the

bars

38 and 39, and extending across the frame substantially diag- -f onally from the respective ends of the intermediate bar 3:: to the opposite side and end bars, are

parallel bars

42 and 43, spaced apart a distance slightly greater than the width of the supporting frame or subtable 30, and which extend parallel with the sides thereof so that one of the corners 4d of the jogging table is positioned so a bisector extends at substantially right angles to the tilting axis of the supporting frame. The frame 35 is provided with a top member 45 which preferably rests on resilient cushion strips 46 on the upper faces of the bars of the frame, said top member being secured to the frame 35 by suitable fastening devices 47. The table top member extends outwardly beyond the frame bars on each side of the corner 44 and is adapted to be engaged by edge guides or fences 48, as later described.

Brackets 49 are suitably secured to the frame 39 as by fastening devices 5 and extend therefrom in substantial. parallel relationship with the bars 42 and 3. The brackets are preferably arranged at each corner of the frame 39 and have side faces substantially registering with the inner side faces 51 of the bars 4-2 and 43. Connected with the side faces of the brackets thus described are spring leaves 52 spacingly retaining the table 31 in spaced parallel relation with the supporting frame 30, the upper ends of the spring leaves being secured to the

respective bars

42 and 43 by fastening devices 53. The lower ends of the spring leaves are secured to the brackets 4) by similar fastening devices 54. The fas tening devices 53 and 54 and connection of the spring leaves to the brackets and bars are such as to permit bending of the spring leaves without overstressing any portions thereof. The table 31 is thus resiliently supported by the spring leaves and since the spring leaves are arranged in planes extending transversely of the pivotal axis of the supporting frame 30, the table is adapted to vibrate with respect to the supporting frame with the bisector of the corner 4 shifting relative to the tilting axis.

The frame 30 is provided with a bore 55 having antifriction bearings 56 therein for rotatably mounting a shaft 57 which extends through the supporting frame 36), said shaft 57 rotating about an axis that is substantially perpendicular to the table 31. The shaft is preferably offset from the bisector of the angle 44 and substantially on the median line of the supporting frame 3t. as defined by the The trunnions 29. A pulley 58 is fixed on the depending portion of the shaft 57 and said pulley is driven by a belt 59 operating over a drive pulley 69 on a motor 61 which is suspended below the supporting frame 3%) by a bracket 62. An eccentric 63 is adjustably secured to the portion of the shaft extending upwardly above the supporting frame 30, whereby said eccentric is rotated by the shaft 57 and operates an eccentric strap 64 journalled on the eccentric.

Spaced rocker arms 65 are journalled on stub shafts 66 extending upwardly from the supporting frame 38, the stub shafts preferably being spaced on opposite sides of the axis of the trunnions 29 and in alignment with the bisector of the angle 44. The rocker arms have portions extending toward the side of the supporting frame 3%) opposite the eccentric 63 to form weighted ends 67. The rocker arms also have arms 68 extending outwardly toward the

bars

38 and 39. The adjacent portions of the rocker arms 65 are notched as at 69 at the journalled ends thereof to form seating faces cooperating with similar faces on :1 lug 70 of the eccentric strap 64 to attach spring leaf connectors 71. The spring leaf connectors are rigidly secured to the respective faces by fastening devices 72 whereby the spring leaves are edgewise to the support ing table, as illustrated in Fig. 8.

Extending inwardly from the

bar members

38 and 39 are brackets 73 having inner faces thereof substantially registering with the outer faces of the arms 68 to be connected by spring leaves 74, the spring leaves 74 being rctained by suitable fastening devices 75 whereby said spring leaves are edgewise to the supporting table 36. Rotation of the eccentric 63 incidental to actuation of the shaft 57 oscillates the rocker arms 65, which oscillation is transmitted through the spring leaves 74 to the table 31 to effect vibration of the jogging table whereby sheets placed in a stack on the table are caused to shift against the edge guide or fence 48 at one side when the table moves in one direction and then against the edge guide or fence at the other side when the table moves in the opposite direction, resulting in alignment of the guide engaging edges of the sheet. The arrangement of the leaf springs 52 and the table vibrating mechanism moves or vibrates the jogging table transversely of a plane bisecting the corner 44. Therefore the movement of the sheets is laterally to alternately engage opposite guides or fences 48, and when the table is tilted to lower the corner 44 the vibration of the table will cause gradual downward movement of the sheets until adjacent edges thereof are engaged by the guides or fences 48 which form a pocket whereupon the sheets are retained in engagement with the guides or fences and do not become disarranged because of continued vibration.

The jogging table is elevated to a desired height for facilitating movement of stacks of paper sheets onto and off of the table, and is lowered and tilted to a desired angle for the jogging operations. The level and tilt positions of the table are obtained in response to the raising and lowering operations by structure now to be described.

A collar 76 is fixed on one of the posts 9 adjacent the upper end of the respective sleeve member 7 when the table is in lowered position. The collar is provided with a laterally extending ear 77 on which is pivotally mounted one end of a rod 78 which extends through and is slidably mounted in a bore 79 of a stub shaft 30 that is journalled in a bracket 81 depending from the supporting table, preferably adjacent a corner thereof on the opposite side of the axis of the trunnions 29 from the corner 44 of the jogging table, as shown in Figs. 2 and 4.

Collars

82 and 83 are adjustably secured on the rod 78 adjacent the respective ends thereof. Other collars 84 are slidably mounted on the rod 78 and adapted to engage opposite sides of the stub shaft 8%. Springs 85 and 35 are sleeved on the rod 78 between the collar 82 one of the collars 84 and the collar 83 and the other collar 84 respectively, whereby when the jogging table is in level position the spring 85 is compressed and the spring 86 extended as illustrated in Fig. 4, and when the table is in tilted position the spring 86 is compressed and the spring 85 extended as illustrated in Fig. 2. Adjustment of the

collars

82 and 83 provides proper balance of the spring pressures at an intermediate tilting position of the jogging table. A rod 87 is pivotally mounted in a bracket 88 on the opposite corner of the supporting frame 30, said rod depending from the supporting frame and having spaced arms 89 extending laterally therefrom adjacent the lower end thereof. Each of the arms has apertures 90 for slidably mounting same on a column 91 fixed as at 92 on the plate-like member 3 and extending upwardly therefrom.

Collars

93 and 94 are adjustably mounted on the column 91 above and below the arms 89, the

collars

93 and 94 being positioned whereby raising of the jogging table moves the arms 89 upwardly on the column 91 and effects engagement of said arms with the collar 93 as the jogging table approaches its desired elevation, engagement of the arms 89 with the collar 93 restricting elevation of the upper portion of the tilted table whereby further upward movement of the posts 9 raises the corner 44 to level the jogging table. Lowering of the jogging table reverses the movement thereof and as the table starts its downward movement the compression of the spring 85 urges the table to partially tilted position. Continued downward movement of the table moves the arms 89 out of engagement with the collar 93 and the compression of the

springs

85 and 86 reach a balance during further downward movement of the table. As the table approaches its lowermost position the arms 89 engage the collar 94 whereby further downward movement of the table compresses the spring 86 and further tilts the table to the desired angle for jogging operations.

It is preferable that the motor 61 be controlled separately from the motor 26, whereby the actual vibration of the table is only when it is in lowered tilted position. It is also desirable to control the operation of the motor 26 to automatically stop the raising and lowering of the table when it is level in its upper position and when it has the desired tilt in its lowered position. This control is effected by a switch mechanism 95 operated by a hinged arm 96, the switch mechanism being carried on a bracket 97 which is fixed on the post 9, opposite the one carrying the collar 76, whereby the switch arm 96 is adjacent the column 91. Laterally extending

fingers

98 and 99 are provided on the

collars

93 and 94 respectively, in position to engage the lever 96 as the table approaches its elevated and lowered positions respectively. A slotted plate is arranged on the switch mechanism 95 whereby the slots 100 therein cooperate with the lever 96 to retain same in circuit-closing position for elevating and lowering operation of the motor 26 until engagement of the lever 96 with the

fingers

98 and 99 return the lever to circuit-breaking positron.

To facilitate movement of stacks of sheets of paper onto and off of the table the edge guides or fences 48 are mounted on the jogging table whereby they may be locked in upright position or dropped below the table, as desired. In the structure illustrated the

bars

36 and 37 on each side of the corner 44 are provided with a plurality of laterally extending lugs 101, the outer faces of which register with the outer edges of the overhanging portions of the table top 45. Each of the lugs 101 has T-shaped slots 102 opening from the bottom and outer edges thereof. The guides or fences 48 have inner faces 103 adapted to engage the outer edges of the table top 45 and lugs 101 when the guides are in operative position. The guides are provided with a plurality of arms 104 suitably secured to the lower edges thereof and extending under the lugs 101 and bars of the table, the arms 104 being pivotally mounted as at 105 on brackets 106 suitably secured to the bars of the table. The guides or fences are provided with bolts 107 slidably mounted in the lower portions thereof and having heads 108 on the inner ends thereof adapted to engage in the T-shaped slots 102, springs 109 being sleeved on the bolts to urge the heads away from the faces 103 of the guides. The outer ends of the bolts are provided with heads 110 on which are trunnioned cam levers 111, said levers having cam surfaces 112 adapted to engage members on the guides or fences whereby downward swinging movement of the cam levers releases the bolts and upward movement of the cam levers draws the bolts through the guides and moves the heads 108 thereof into engagement with the T-slots 102.

In operating a jogging machine constructed and assembled as described, and assuming the table is in elevated position and level, the cam levers 111 on one side of the table are moved downwardly to release the heads 108 of the bolts 107 from the T-shaped slots 102 whereby the guides 48 are swung downwardly below the table. The levers 6 are then operated to raise the foot members whereby the jogging machine may be rolled to position the jogging table adjacent a support for a stack of paper sheets to be jogged. A stack of sheets is then slid onto the table top 45 and the guide or fence swung upwardly into engagement with the edges of the table top. The cam levers 111 are then swung upwardly to engage the heads 108 in the T-slots 102 to lock the guides or fences in operative position. The levers 6 are operated to lower the foot pads or members into engagement with the floor to prevent rolling of the machine. The lever 96 is then moved in the slotted plate 100 to swing the finger-engaging portion of the lever downwardly. This movement of the lever operates the switch mechanism to close the circuit to the motor 26 whereby it rotates the sprocket 24 to drive the chain 23 and rotate the screws 17 to screw same into the posts 9 to effect lowering of the jogging table.

In the first portion of the lowering action, the spring applies pressure to the stub shaft 80, tilting the table until the

springs

85 and 86 are balanced. Then continued lowering movement moves the arms 89 downwardly on the column 91 until they engage the collar 94. At approximately the same position, the finger 99 engages the end of the lever 96. Further lowering movement of the table effects further tilting thereof because the arms 89 and stiff rod 87 prevent further lowering movement of the portion of the table engaged thereby. The continued movement downwardly of the table also moves the lever 96 to neutral position to break the circuit to the motor 26, stopping same, whereby the table is at the desired tilt with the corner 44 thereof in lowermost position. The motor 61 is then energized to drive the eccentric 63 to effect oscillation of the rocker arm 65 and vibratory movement of the table transversely of the bisector of the angle of the corner 44. This vibratory movement jogs the paper into said corner with the edges of the sheets in the stack in engagement with the guides or fences until all of the edges of said sheets are in registry.

When the stack of paper is jogged, the circuit to the motor 61 is broken to stop the jogging action. The lever 96 is then swung to move upwardly the finger-engaging end thereof and also close the switch to reverse the operation of the motor 26 to screw the screw 17 outwardly relative to the post 9 to effect elevation of the table. During the first portion of the upward movement of the table, the compressed spring 86 effects swinging movement of the table on the trunnions 29 to intermediate tilted position. The elevation is continued until the arms 89 engage the collar 93 whereby continued movement of the table tends to move same to a level position. At the same time the lever 96 is moved into engagement with the finger 98 to effect swinging thereof to neutral or circuit-breaking position, the collar and finger thereon being adjusted whereby the motor 26 is stopped when the table is in level position. The cam arms 111 are then operated to release the guides or fences to prevent downward swinging movement thereof. The levers 6 are then operated to raise the foot members whereby the table may be rolled to the feed table of other equipment for further processing of the paper. The jogged stack of paper is then slid from the table top 45 onto the feed arouses 2 table of said other equipment. The jogging machine is then ready to be moved back to the position to receive another stack of paper to be jogged.

From the foregoing it is obvious that l have provided a jogging machine which efiiciently registers the edges of loose sheets and also facilitates the application and removal of sheets of paper from the jogging table yet performing the jogging operation when the table is in a relatively low position for maximum stability thereof.
