(Cl. 93-93) The present invention relates to an improved apparatus for efiiciently and reliably dividing a stream of commodities which continuously follow one another in succession, particularly copies of folded newspapers, periodicals and the like.

It will be appreciated that folded newspapers, periodicals and the like coming out of a printing machine or folding machine in a continuously moving stream must be transformed into counted groups for further distribution. This is effected in known manner by means of an apparatus using a counter for counting the copies and after reaching a count corresponding to a predetermined number of copies it delivers a control pulse.

The present invention has for one of its primary objects to provide improvements with respect to apparatus of such type.

A further object of the present invention is to provide an improved apparatus for reliably and efficiently subdividing a stream of commodities, particularly a stream of copies of folded newspapers, periodicals or the like which continuously follow one another in succession.

Another object of the present invention is to provide improved apparatus for sub-dividing a continuous stream of goods into groups containing predetermined numbers of such goods, such apparatus operating with extreme reliability and with high precision, while still being relatively simplified in construction.

A characteristic of the present invention is that the counter is arranged at an earlier or upstream location with respect to the direction of movement of the stream of copies and adjustable means are provided which are located at a later or downstream location with regard to the stream of copies and respond to a control impulse or pulse for controlling a separation lever for sub-dividing the aforesaid copy stream into predetermined groups. The adjustable means delay the movement of the separation lever until the last copy of a group which is to be divided-out has passed a separation station or location, whereafter it arrests the separation lever at such separation location for the purpose of providing a break or interval in the stream of copies and permits such separation lever to again return back into its starting position after releasing the stream of copies. Advantageously, a plurality of continuously meshing gears driven by a drive motor are connected via slipping clutches with switch arms and the drive wheels'or equivalent drive mechanism for the separation lever. For example, rotary or swivel levers are provided for locking and releasing the switch arms. The physical structure can be executed such that the switch arms are adjustably arranged with regard to their angular position upon their associated shaft. A number of the switch arms and also the separation lever can be constructed as double-arm levers equipped with two ends staggered from one another through 180.

An illustrated preferred embodiment of the invention is constructed such that the counter delivers a control pulse to an electromagnet which actuates a locking bar for a switch arm. As a result, control of the separation lever takes place in accordance with the movement of 3,3l3,22l Patented Apr. 11, I967 switch arms which lock or block the separation lever after having reached the separation location due to abutting of a switch arm against a rotary or swivel lever, with release of the locking action taking place by the abutting of another switch arm against a swivel or rotary lever. Furthermore, there exists the possibility of moving the stream of step-like stacked newspapers or other goods by means of suitable conveyor bands or transport means driven with constant or continuous speed.

Other features, objects and advantages of the invention will become apparent by reference to the following detailed description and drawings in which:

FIGURE 1 is a side view of an embodiment of inventive apparatus for the sub-division of a stream of continuous copies of folded newspapers, periodicals or the like successively following one another;

FIGURE 2 illustrates the apparatus of FIGURE 1 in operating condition for separating or sub-dividing the stream of copies:

FIGURE 3 illustrates the apparatus of FIGURE 1 after having completed division of the stream of copies; and

FIGURE 4 is a plan view of the apparatus shown in FIGURES 1 to 3, and which for convenience of illustration only schematically has depicted therein the switch arms.

As shown in the drawings, the apparatus according to the invention incorporates conveyor bands or transport means 5, 6 and 7 travelling over respective rollers 1, 2 and 3, and 4 (only a single roller is visible for conveyors 5 and 7), and upon which commodities, in the present instance assumed to be a strezun of copies ii of folded newspapers for example, stacked on top of one another in step-like manner, are continuously moved in the direction of the arrow 9. Each conveyor 5, 6 and 7 can embody two pairs of spaced coaxial rollers, such as a first pair of rollers 2 and a second pair of rollers 3 when considering conveyor 6, with only the forwardmost rollers of each pair being visible in the drawing. Furthermore, a band, such as member 6a, extends over the forwardmost rollers 2, 3 and a further spaced band (not shown) over the rearwardmost rollers. Due to such physical construction there is provided a space between these band members into which a double-arm separation lever 23 can move, as will be more fully explained as the description proceeds. Naturally, other constructions of the conveyor means, 5, 6, 7 are possible. The number of through-passing copies 8 is recorded by means of a suitable counter 159 located at an earlier or upstream location viewed with respect to the direction of movement of the aforesaid strem of copies 8. When the count determined by the counter 10 has reached a predetermined adjustable value a control impulse or pulse is delivered to an electromagnet 11.

The electromagnet i1 is spaced from the counter 11 and supported at a later or downstream location, viewed with respect to the direction of movement of the stream of copies 8, upon a plate member 12. This electromagnet 11 cooperates with a locking bar or bolt 14 having a locking nose 14a and loaded by a spring member 13, such locking bar 1 locking a revolving switch or control arm 15 seated upon a rotatable shaft 29, as best ascertained by reference to FIGURE 1. The locking bar 14 together with the switch arm 15 provide means for locking :or blockin the entire system, as will become more readily apparent as the description proceeds. Moreover, a gear 17 is driven by a gear 16 of a suitable drive motor 16a, the aforesaid gear 17 meshing with a further gear 18, the latter of which, in turn, meshes with a gear 19. Asprocket wheel 26 is coaxially arranged with respect to the gear 18. Such sprocket wheel 20 drives a sprocket wheel 22 through the agency of a sprocket chain 21 and thereby also drives the commodity separation of division lever 23.

As best seen by referring to FIGURE 4, the gears 17, 18 and 19 are operatively connected via conventional slip couplings 24, 25 and 26 respectively, with shafts 27, 28 and 29 respectively, carrying revolving switch or control arms. More specificially, and as schematically represented in FIGURE 4, the shaft 29 carries the switch arms 15, 31, 34 and 38 which are adjustable in angular position thereon for reasons to be explained, the shaft 28 carries the switch arms 33, 35 and 36, and the shaft 27 the switch arm 40. The particular function performed by these various switch arms and their cooperation with one another will be explained hereinafter. It is to be appreciated that while the gears 17, 18 and 19 driven by the drive motor 16 continuously revolve, the sprocket wheel 20 and there-with the separation lever 23 cannot be placed into rotary motion so long as the shafts 27, 28 and 29 are locked, that is, during such time as the locking bar 14 engages with the swivel arm 15 to prevent rotation of the latter.

It is assumed that the number of copies 8 correspond ing to a group to be divided-out has passed the counter 10 and the electromagnet 11 has received a control pulse. Due to the excitation of the electromagnet 11 the locking bar 14 is rocked in counter-clockwise direction and is released from its locking action with the associated switch or control arm 15. The thus released switch arm 15 can now revolve clockwise in the direction of the arrow 30, whereby also the other switch or control arms 31, 34 and 38 seated upon the shaft 29 can partake in this movement.

After undergoing a particular magnitude of rotational movement the switch arm 31 abuts against a springbiased rotary or swivel lever 32 which up to now has blocked the switch or control arm 33 of the shaft 28. The swivel lever 32 and cooperating switch arm 33 constitute a means for directly blocking or locking the separation lever 23, whereas the switch arm 31 and swivel lever 32 constitute means for releasing the locking action imposed upon such separation lever 23. The release of such locking action results in movement of the sprocket wheel 20 seated upon the shaft 28 which then entrains the sprocket wheel 22 via the sprocket chain 21. During such movement the commodity separation lever 23 moves from the reset position, shown in FIGURE 1, into the position depicted in FIGURE 2 at the separation location A at which the stream of copies 8 is divided or separated, as shown.

The copies located in front of the separation position A, that is downstream with respect to their direction of movement correspond in number to a counted group. They continue to travel undisturbed until they are gathered together into a package by means of suitable special apparatus known in the art. During the above discussed movement of the separation lever 23, the switch arm 34 also abuts against the switch arm 35 of the shaft 28 and thereby accelerates the movement of the swiveling separation arm 23. Hence, switch arms 34 and 35 constitute a means for accelerating the separation lever 23. The arresting or stopping of this separation lever 23 at the separation location or position A results from abut ting of the switch arm 36 seated upon shaft 28 against a spring-biased rotary or swivel level 37, as best shown in FIGURE 2. Thus, switch arm 36 and swivel lever 37 can conveniently be considered to constitute means for arresting the separation lever 23 at separation location A.

The described apparatus has the purpose of delaying the separation lever 23 in its movement after the arrival of a control pulse in such a manner that it arrives at the separation location or position A exactly at that period of time in which the last copy 8a (FIGURE 2) of the counted group has passed this separation location.

After a given interval which guarantees for a suflicient distancing or spacing of the divided-out group of commodities, the arresting action of the separation lever 23 at separation location A is released, to thereby render possible further movement of the banked or dammed-up stream of copies 8. This occurs by means of the switch arm 38 revolving upon the shaft 29 and which displaces a spring-biased rotary lever 39 from its locking position with regard to the switch arm 40, whereby switch arm 40 moves the rotary lever 37 in such a manner that the abutting switch arm 36 is released and the separation lever 23 leaves the separation position, as best seen in FIGURE 3. Thus, switch arms 38 and 40 together with swivel lever 39 constitute means for releasing the arresting action of the separation lever 23 at separation location A, so that such lever 23 can now continue to rotate back into its starting position.

The separation lever 23 is advantageously constructed as a double-arm lever possessing two diametrically opposed ends 23a, 23b (FIGURE 1) olfset by The further movement of the separation lever 23 is stopped as soon as the free end 15a of the switch arm 15 engages with the nose 14a of the locking bar 14. As a result, the preparatory or starting position of the separation lever 23 depicted in FIGURE .1 is again attained. After a re-newed control impulse or pulse the described operation repeats itself, whereby only the other end of the switch arms 33, 35, 36 and 40 constructed as double-arm levers come into operation, such ends conveniently being designated by reference characters 33', 35' 36 and 40 respectively (see FIGURE 1).

A requirement for the control of the installation is that the movement of the conveyor means 5, 6 and 7 and the gears 17, 18 and 19 and the switch arms 15, 31, 34 and 38 respectively, occurs synchronously. This is achieved in that, drive motor 16a drives the gears 17, 18 and 19 as well as also the conveyor means 5, 6 and 7. During such time as the last copy of a group travels past the counter 10 and triggers the control pulse the switch arms 15, 31, 34 and 38 seated upon shaft 29 are entrained by the rotating gear 19. As a result, the last copy of the group arrives at the separation location A at the same time as the separation lever 23. The delay in time in which the separation lever 23 after arrival of the control pulse must be delayed is thereby determined by the angular difference between the switch arms 15 and 31. For a different spacing of the counter 10 from the separation location this angular difference can be changed by positionally adjusting these switch arms 15, 31 as well as the switch arms 34, 38.

The same control can also be used for still other purposes. In so doing, there is associated therewith, for example, the stacking of a number of commodities or copies on top of one another and the ejection of the completed package.
