Description

DETAILED DESCRIPTION OF THE INVENTION B. Prior Art It is well known that newsprint normally moves from a printing press at high speeds and is conveyed a considerable distance Ke in an edge-to-edge stream Jlf. ing.

Conveyance is usually accomplished by a plurality of opposed spiral endless wire conveyor ribbons or opposed pairs of elongated strips placed at spaced apart positions across the width of the printed paper.

As previously mentioned, the printing paper typically travels a considerable distance from the printing press for counting, stacking, and bundling so that it can be delivered. Traditionally edge-to-edge printed sheets must be moved vertically and then redirected in order to be placed in the appropriate position, e.g. for storage by a stacker. I understand. On the other hand, such wire conveyors are particularly useful for straight horizontal and vertical runs, presenting construction and operational problems when the printed paper must be physically oriented for subsequent operations. However, wire conveyors leave stains on the product due to the local pressure of the wire.

3 Problems to be Solved by the Invention The main object of the present invention is to provide a new device for the use of a newsprint conveyor device that is capable of effectively conveying printed copies vertically while simultaneously achieving orientation of the printed copies. It is to be.

Another object of the present invention is to provide a printing paper conveying device having a pair of opposing belts positioned between the devices for conveying the flow to the top while capturing the central area of the printing paper flow and at the same time achieving its direction. It is to provide.

An additional object is to provide a belt transport and orientation system that reduces localized pressure on the printed paper, thereby minimizing localized defects caused by wire conveyor systems.

Still another object of the present invention is to provide an improved apparatus which utilizes opposing endless belts to grip the printed paper and has a device for guiding the lateral edges of the printed paper so that the printed paper is physically oriented. An object of the present invention is to provide a printing paper conveying device.

Other objects and advantages of the present invention will become fully apparent and explained in full with reference to the accompanying specification and drawings.

C. EMBODIMENTS AND OPERATION Generally, the apparatus of the present invention is for use in conveyor systems used to transport newsprint from a printing press to another location in the operation where stacking is performed. The device basically has a lower support frame arrangement 10 and an upper support frame arrangement 11. Each support frame device 10
and 11 comprises a pair of vertically extending side rails 12 and a plurality of horizontally extending intermediate rails 13 which act in conjunction with the side rails 12'. It will be noted that the upper support frame arrangement 11 is attached to the upper end of the lower support frame arrangement 10 and is rotated through an angle of 90 degrees with respect to the lower part.

For illustrative purposes only, the current description is 9 between the two parts.
Although performed using an angle of 0 degrees, it should be understood that any angle of orientation may be selected if desired. Referring to FIG. 1, the lower support frame apparatus 10 is mounted on top of an infeed apparatus 15 which receives newsprint from a horizontal conveyor, not shown, and is connected to the lower support frame apparatus 10 by a pair of opposing endless belts 16 and 17. It is understood that the newsprint is oriented upwards towards the.

In the infeed device 15, the belt 16, only one of which is visible, is mounted around a plurality of rollers 18, which are pivoted for rotation between the side surfaces 19.

In a similar manner, a plurality of rollers 20 are journalled in the side surface 19 so as to have a guiding device for the belt 17.

The rollers 18 and 20 shown in FIG. 1 are spaced farthest to the right so that the belt 16
and 17 converge towards the centralmost roll 18 so as to define a narrow passage 21 through which the printing paper is fed. belt 16
, the belt 17 moves towards the left rotation as indicated by the arrow 23 , and the printing paper fed into the narrow passage 21 moves from the horizontal towards the lower support frame arrangement 10 . will be carried vertically to.

The rotary member pivoted between the side surfaces 19 of the feed device 15 also has a roller 24 with a cam surface 25 inclined outwardly with respect to the axis of rotation of the roller 24. This roller 24 and cam surface 25 have a belt biasing device which acts to hold the belt approximately centrally between the side rails 12.

The lower frame arrangement 10 includes a plurality of horizontally extending belt guide rollers 3 pivoted for rotation between side rails 12.
1 and 32. The uppermost roller 32 is pivoted in a socket member 33 and supported by a threaded rod 34 as seen in FIG. Can be moved away from the belt. The installation of this adjustment movement is successful in the operation of the current conveyor system because it allows the endless belts 16 and 17 to hold the printed paper in the center of the supporting frame devices 10 and 11, regardless of the thickness of the printed paper being conveyed. It is important to Guide roller 30
has the same structure as the roller 24 and has a cam surface 36. By referring to FIG. 2, the cam surface 25 and the cam surface 36
It is recognized that the belts 16 and 17 cooperate with each other in centering the belts 16 and 17 because they are orientated in plane with each other.

As mentioned earlier, the upper support frame arrangement 11 is mounted on top of the lower frame arrangement shown at some pre-extruded angle, here 90 degrees. Thus, in this description, the lowest guide roll 40, which is pivoted between the side rails 12 of the upper support frame arrangement 11, is at an angle of 90 degrees with respect to the axis of rotation of the various rolls pivoted on the frame arrangement 10 and the infeed section 15. It has its axis of rotation around which it rotates. Upper frame arrangement 11 also supports a plurality of guide, tension and drive rollers that cooperate with one or both of belts 16 and 17.

In particular, it has a guide roll 41 which is pivoted on an arm 42 which is fixed to the upper side rail 12 in cooperation with the belt 17.

Tension rolls 45 and 46 are pivoted on arms 47 that are rotatably mounted on side rails 12. The arm 47 has a tension spring 5 connected at one end to the arm 47 and attached to the side rail 12 via a rod and bracket 51.
with its outer end (left end as shown in FIG. 2) biased upwardly by 0. The drive roll for belt 17 is designated by the number 55. The roll 55 is a gear box 57
It is driven by a motor 56 via.

Belt 16 is guided, tensioned and driven in a similar manner to belt 17. In particular, the belt 16 is passed through a gear box 63 into the side rail 12 over a tension roll 64,65 mounted on an arm 66 rotatably supported on the side rail 12, over a drive roll 61 driven by a motor 62, and into the side rail 12. It passes by a pivotally supported guide roll 60. This arm has its outer end (on the right as seen in FIG. 2) and a tension spring 67 connected between the rod P and the bracket 68.
The bracket is coupled to the side rail 12 by the arm 47 . Finally, the belt 16 passes around a guide roll 75 which is pivoted on an arm 76 attached to the side rail 12. One final guide roll is identified by the number 80 and serves as a guide for both belts 16 and 17 before they begin to separate for their respective return runs.

The support frame arrangements 10 and 11, the side rails 12, the various guide, drive, bias and tension rollers are arranged or oriented as described above, so that the belts 16 and 1
It is clear that 7 can be twisted through any preselected angle made between the roll axes supported by the upper and lower frame devices 10 and 11. The torsion created is caused by the return run of the belt 16 due to the upper guide roller 75.
and the lower guide roller 31 is shown in FIG.

Examining the general function and operation of the belts 16 and 17, the belt 17 runs downwards from the drive roll 55, around the tension rolls 45, 46, the guide rolls 41, 40, 32, the cam guide rollers 25, and on the return run upwards. The last step is to move around the lowest guide roller 20 before departure.

Belt 16 is guided in a similar manner. Starting from the drive roll 61, the belt 16 moves to the roller 64°65.75.3
1.30 and finally around rollers 18 before starting its upward return run. Both downwardly running belts 16 and 17 are twisted 90 degrees in the manner shown in FIG. 6, which shows the twisting of belt 16.

After the belts 16 and 17 are converged in the narrow passage 21,
Since they come together, the printed sheets are entrapped and held between the belts so that they are identified as identical by the numeral 85.

As the belt travels upwards together with the printed paper, it is guided by guide rollers 31 and 32 so that the printed paper assumes the same position identified by the numeral 86. As the printing paper continues upwards, it twists with the belt until it reaches an intermediate position as shown at location 87.
Move from the arrangement direction of 6. Continuing, the paper is further twisted until it has achieved all of the predetermined selected orientations and is positioned as shown at location 88.

During the orientation of the printing paper from position 86 to final position 88 it is essential that the lateral edges of the printing paper are kept in the same relative position with respect to each other throughout. This is effectively achieved by a pair of guide devices 90 and 91. Each guide device has an elongated plate-like element with a terminal end 105, 106 parallel to the axis of rotation of the adjacent guide rolls 40 and 32, respectively. Each such guide element 90,91 is formed with a twist corresponding to a preselected angle existing between the axes of rotation of the guide rollers of the lower and upper support frame devices 10 and 11. The printing paper passes the roller 32 and reaches the point 86.
When traveling upwards from , its lateral edges come into contact with guide elements 90 and 91 .

Continuous travel with a combination of given torsions is elements 90 and 9
1 to press the edges of the printed paper against each other, thereby ensuring that the relationships identified with respect to each other are maintained. This device therefore makes it possible to effectively convey newsprint vertically with simultaneous changes in running direction.

Although the invention has been elucidated in conjunction with preferred embodiments,
It is to be understood that modifications and variations may be resorted to without departing from the spirit and scope of the invention as will be readily apparent to those skilled in the art.
