SYKES CONVEYER CONTROL TABLE 5 Sheets-Sheet 5 Filed June 5, 1949 INVENTIOR. THOMAS R. SYKBS HTTORNEY Automatic operation of the control table When the table pivots downwardly the belts 3 on the control table will be pinched between control table roller 9 and the friction surface of driven roller it. The table is shown in its up position in Fig. 3 and its down or driven position in Fig. 2. The driven roller it may be driven in a suitable manner. Shown diagrammatically in Fig. 5 is a motor ll which drives a belt it to gear reduction pulley l9 which in turn drives i751?) chain 2b to sprocket 2! which drives a chain to a sprocket 23 on the shaft of the roller is. The drive means is eliminated from the other views for the sake of clarity.

As soon as the table drops, the belts 8 will be rotated around rollers 6 and l as described above. An idler roller 24 shown particularly in Figs. 2 and 3 is journalled on

links

25, 25 pivotally mounted on control table frame members 3 and t. Another idler roller 26 is journalled on frame members it and when the table drops the roller 24 is pressed upwardly by roller 26 to engage the underside of the belts B and said belts rotate the roller 24 to feed the sheet or web of wrapping paper W, which is pounded between said rollers, upwardly past the front end of the control table and over the driven roller 28 which preferably has a friction surface.

Roller 2.6 is driven by chain 2% as shown in Fig. 5 by means of a sprocket tea on roller it. Therefore roller 23 is continuously rotating but since the end of the paper W merely rests on it there is not sufficient friction to feed the web of wrapping paper W until roller 24 is caused to rotate by the dropping of the control table, so that paper is fed only when the conveyor portion of the control table is in operation carrying the pile of papers from right to left in the drawings towards

feeding rollers

30, 3i and 32 which are also driven by chain 29 as shown in Fig. 5. The paper as it passes ofi the control table presses the wrapping paper W against

rollers

28, 39, Si and 382 so that the wrapping paper is carried along underneath the stack of newspapers as illustrated in Fig. 3. In fact the friction between the lift of papers and the rollers is sufficient to carry the Web of wrapping paper W beneath the lift of newspapers and the chief purpose of roller 2a is to keep the web out of contact with roller e, which would tend to push the web back. Rollers 36, iii and 32 are not necessarily driven rollers since the momentum of the lift of papers would carry it over idler rollers. These rollers are the first stage of a receiving table or conveyor on which the stack of papers may be tied and from which it may be delivered to a truck or other means for distributing the papers to the consumers.

Semi-automatic operation It will be observed that the starting of the conveyors on the control table is automatic, as described above, the mechanism operating'as soon as enough papers have been placed on the control table to cause it to drop. However, for some purposes it is desirable to operate the device manually or rather semi-automatically, particularly when stacks of paper containing different numbers are required and for this purpose means is provided for preventing the automatic actuation of the control table. This means is shown chiefly in Figs. 1 and 6 but partly also in Figs. 2 and 3.

Rotatably mounted in the fixed frame of the machine at the rear of the beams II and I2 is a shaft 33 having secured thereto at one end a cam member at; and at the other end a cam member 35. The beam H has a rearwardly projecting portion lib adapted to be engaged by the cam 3Q- when the shaft 33 is rotated by the operator by a handle or other suitable means. In Fig. 1 the cam 34 is shown out of engagement with the projection lib and in Fig. 6 is shown in engagement with the projection l lb, thus tilting the arm ll upwardly so that the projection Ha at the other end of the arm is out of engagement with the table frame member 3 and provides no support for the table. When the table is not supported by the beam H, it is supported only by the beam l2 and weight l5, which is just sufficient to hold the table in its up position, but the placing of a small number of papers on the table will cause it to drop. To prevent it from dropping a latch 36 is pivotally mounted on a pin to which is secured to the machine frame. This latch 36 has a hook 36a adapted to engage a projection 212 on the beam it. When the device is in normal fully automatic actuatin position the latch 36 is held out of beam engaging position by means ofthe cam 35 as shown in Fig. i, but when the device is in manual or semiautomatic operating position by virtue of rotation of the shaft 33, the cam 35 disengages the latch and compression spring 36b forces the tail of the latch up so that hook 3Ea is in engaging position as shown in Fig. 6. When the control table rises to up position, the curved end of the projection 521) will engage the curved nose of the hook 35a and the catch will be pushed back and then will snap over the end of the projection !2b as shown in Fig. 6, thus holding it in up position so that when papers are put on the table, the table will stay in up position and will not drop to the positionat which the table conveyor is operated.

When the operator of the device has placed the desired number of papers on the control table, by actuating a suitable switch, not shown, a solenoid 39 shown diagrammatically in Figs. 1 and 6 will be actuated to pivot the catch against the pressure of spring 3% causing hook 36a to move out of engagement with the projection 2b, so that the catch no longer restrains the beam i2 from pivotin and the beam will therefore swing up permitting the control table to drop into operating position so that the papers are carried off the control table in the manner hereinbefore described. Details of the means for operating the shaft details of the solenoid 39, and details of the electrical circuit are omitted as they do not form part of the invention and may be of any suitable construction.

Wrapping material feedin and perforating means As hereinbefore described a sheet or web of wrapping material such as kraft paper is fed to and under the stack of newspapers. The wrapping material is wound around a spindle 40 suitably journalled on brackets ll mounted on a machine frame member. As shown in Figs. 2 and 3 a supplementary roll of material is provided for use when a roll is being removed and inserted in the machine, but this need not be specifically described. The web of wrapping material W passes under an idler roller 42, over a driven roller 4-3, under an idler roller M and over rolls 26 and 28 as hereinbefore described. Roller 43 is driven as shown. in Fig. 5 by the chain 29 which also drives the. conveyor rollers at the Sflme; n E Driven roller 3x15511015 ,nrlmarfln gausetsnrinstmetaa areavseouredzto the-sideszofathet thefeedingilmeansaforetheweb's Theigrimermoven channelsi andififlandubentat rovideisresilientt of the web? is; the?- pulll exerted thereon; when; it's. guidessSB and:59ibetweenvwhiohathawebfoiiWraps free: end is: damned; beneath. moving, staeka of; pins; materiahVP passes.

The friction between the lift of newspaper I and the rollers 30, 3'! and 32 holds the portion of the web of paper which is underneath the pile of newspapers and continues tocarry that portion of the web forwardly, so that the web of paper is torn alongthe line of perforation at the same time that a new line of To ensure that the web is torn along the line of perforation .a breaking mechanism is provided actuated by. the air cylinder. This-breaking" mechanism consists'of three vertical bars 75,

l6 and W shownclearly in Fig. 4 but also shown in Figs. 2 and 3 retained between uides Hi5, and adapted to pass between the rollers 28 and iii. The bar 15 is supported on vertical rod l8 and th'e'bar .7! is supported on vertical rod 19, the

central bar 16 being supported on rod til secured to a cross-bar 8|. lhe rods 18 and is are pivotally connected to bell-crank levers s2 and '63 respectively which are pivoted to fixed transverse shaft 84. The other ends of bell-crank

levers

82 and 83 are pivotally connected to

rods

85 and 86 respectively and these rods are pivotally secured to

arms

81 and 88 secured to shaft ill. By this arrangement of links and levers rotation of shaft 51 by means of air-cylinder l2 willforce the vertical bars '55, it and Ti upwardly against the web of wrapping paper W at the same time that the anvil is pressed down on the cutting blade to perforate the web, thus providing a positive breaking means for the web of paper along the line of perforation.

, Positive table lifting mechanism Although when the stack of paper passes oil the control table, it will automatically lift out of engagement with the drive roller It, it may be desirable to provide some positive means for initiating the lifting movement and this maybe accomplished by means of a supplementary air cylinder 89 in parallel with the air cylinder l2, shown particularly in Fig. 4. This cylinder is mounted on frame member l3 andis connected to .n electrical circuit for actuating the sheet perforating and severing means is shown diagrammatically in Fig. 8. Current froml-a source of power passes through wire 92, in which may be located the limit switch I06, to switch 65, be-

ing connected to switch arm 62 which is normally in the position shown in contact with contact 64. Contacts 93 and. 94 of relay 95 are normally open. When the arm 60 is depressed, switch arm 62 is raised to engage contact 63 completing a circuit through the relay coil 96 and making the

relay contacts

93 and 94. When the arm 69 raises after a stack of newspapers has passed over it, switch arm 62 will engage contact 54, completing a circuit through line 91, relay contact 94, and line 93 to the valve operating solenoid 66 thus actuating the air cylinder as previously described. The relay remains closed since the relay'coil is in circuit through line 99 including contact 93. When the perforating operation is complete the limit switch I06 is opened and the relay circuit broken, breaking the

relay contacts

98 and 94 and de-energizing the solenoid 66, thus the cycle;
