Abstract

Printed products arriving in an imbricated formation are wound-up into a product or package roll about which there is placed a wrapper or envelope which retains together the package roll. For easier handling of the product or package roll such may be provided with an endless carrying loop. This endless carrying loop is formed by a carrying element, such as a knotted cord, rope, string or the like which extends through an internal opening or hollow interior of the product or package roll and to the outer side or surface of such product or package roll.

Description

The present invention relates to a method and a device for producing portable, tubular packages from printed products, such as newspapers, magazines and the like, according to the preamble of claim 1 and claim 5, and a package according to the preamble of claim 14.

From DE-OS 3 330 485 or the corresponding GB-OS 2 126 188, it is known to form ready-to-ship packages by rolling up print products resulting in scale formation, which can be transported by hand and which the individual print products can be removed from the center of the packages. The roll is prevented from falling apart by wrapping or strapping around it.

The present invention is based on the object of creating a method and a device which allows the production of printed product rolls of this type, which can be handled even more easily, without too much additional effort.

This object is achieved according to the invention by the features of the characterizing part of claim 1, claim 5 and claim 14, respectively.

The roll can easily be grasped and manipulated by hand on the closed carrying loop surrounding the roll and extending in its longitudinal extent. This carrying loop can be formed with relatively little effort after the production of the roll, especially if the support element is passed through a winding mandrel onto which the printed products are wound and after the roll has been completed, it is pulled off the winding mandrel, from which now the carrying loop is formed in the inside of the roll-carrying element. The support element is preferably held at one end outside the winding mandrel and when the roll is pulled off the winding mandrel from a storage device, e.g. a supply roll.

A device for the mechanical production of a roll provided with such a carrying loop is of simple construction if it is designed as defined in claims 6 to 13.

1 and 2, a device for forming printed product rolls provided with a closed carrying loop will now be explained, FIGS. 3 to 8 also having to be taken into account in order to understand the structure and mode of operation of this device.

The device mentioned has a frame designated by 1, in which two belt conveyors 2 and 3 are arranged one behind the other. The first belt conveyor 2 is used to feed the printed products 4 which are to be wound up into a roll and accumulate in scale formation S to a winding point 5. The conveying direction of the belt conveyor 2 driven by a drive unit 6 is designated by B in FIG. 1. Each printed product 4 rests on the subsequent printed product in the supplied scale formation S. This means that the leading edge 4a of the printed products 4 lies in the supplied scale formation S on the underside thereof. The second belt conveyor 3 is arranged in a carriage 7, which is supported by means of two guide rods 8 in a guide 9 arranged in the frame 1 and can be moved back and forth in the direction of arrow C (FIG. 1). One arm of an angle lever 10, which is pivotably mounted in the frame 1 about the shaft 10a, engages on this carriage 7. The other arm of the angle lever 10 is coupled to a cylinder-piston unit 11. By means of this cylinder-piston unit 11, the angle lever 10 is pivoted into the position denoted by 10 'and the carriage 7 is displaced in the direction of arrow C in order to move the belt conveyor 3 from the active position shown in broken lines in FIG. 1, in which this belt conveyor 3 located at the take-up point 5 in a release position, which is shown in Fig. 1 with solid lines and is designated 3 '.

At the winding point 5 there is also a hollow cylindrical winding mandrel 12 which has a through channel 12a extending in the longitudinal direction thereof. This winding mandrel 12 is freely rotatably mounted on a pivot lever 13 which is pivotally seated on a shaft 14. The pivot lever 13 and with this the winding mandrel 12 can be pivoted in the direction of arrow D (FIG. 1). In Fig. 1, the pivot lever 13 and the winding mandrel 12 are shown with solid lines in their lower pivot position, while the upper pivot position of the pivot lever and the winding mandrel is dash-dotted and designated 13 'and 12', respectively. In its lower pivot position, the pivot lever 13 is in contact with a stop 15.

The winding device also includes an endless belt 16 which is guided over a number of deflection rollers 17 to 22. Of the latter, the deflection rollers 17, 18, 19 and 21 are fixed in place in the frame 1, while the deflection rollers 20 and 22 are pivotally mounted. For this purpose, the deflection roller 20 is mounted on one end of a lever 23 which is pivotally seated on the other end on a shaft 24, the longitudinal axis of which coincides with the axis of rotation of the deflection roller 21. The lever 23 and with this the deflection roller 20 can pivot back and forth in the direction of the arrow F (FIG. 1). One end position of lever 23 'and roller 20' is shown in dash-dot lines,

while the other end position is shown with solid lines and designated 23 and 20 respectively. The deflection roller 22 is mounted on one end of a two-armed lever 25 which is pivotably mounted about a shaft 26 arranged in the housing in the direction of the arrow G (FIG. 1). A cylinder-piston unit 27 acts on the other lever arm, which pivots the lever 25 together with the deflection roller 22 into the upper end position 25 ', 22' shown in solid lines. The lower end position of the lever 25 and the deflection roller 22 is shown in broken lines. The deflection roller 17 is driven clockwise by the drive unit 6, so that the belt 16 is driven in a rotating manner in the direction of the arrow E (FIG. 1).

At the beginning of the winding process, the pivot lever 13 with the winding mandrel 12 is in the lower position, shown in solid lines, while the deflection roller 22 assumes the end position shown in broken lines and the deflection roller 20 in the end position, shown in solid lines. The belt 16 now runs from the deflection roller 17 over the deflection rollers 18 and 19 to the deflection roller 20, from this over the deflection roller 19 to the deflection roller 21. From this deflection roller 21, the belt 16 runs along the lower run of the belt conveyor 3, and then on the top of the upper strand to the winding mandrel 12, which is looped around by the belt 16 along part of its circumference and then continuously via the deflection roller 22 to the deflection roller 17. The belt 16 is partially shown in broken lines. The belt conveyor 3 is driven in rotation in the direction of arrow H (FIG. 1) by the belt 16.

The scale formation S fed by the belt conveyor 2 arrives on the second belt conveyor 3 and the belt 16 lying on the winding mandrel 12, which is driven by the belt 16 in the counterclockwise direction. The supplied scale formation S is wound between the winding core 12 and the belt 16 lying on the winding core 12. As the radius of the printed product roll that lies on the belt conveyor 3 increases, the winding core 12 is raised and given upward in the direction of arrow D about the pivot axis 13a defined by the shaft 14. The deflecting roller 22 is also pivoted upward in the direction of arrow G by the increasing print product roller. To compensate for the length of the endless belt 16, the arm 23 pivots with the deflection roller 20 in a counterclockwise direction from the position indicated by 23 or 20 in the direction of arrow F against the end position indicated by 23 'or 20'. The formation of the printed product roll will be discussed in more detail later in connection with FIGS. 3 to 8.

At the winding point 5 there is also a plate-shaped ejector 28 which is attached to one end of a rod 29 which is guided in a bearing 30 in the direction of the arrow L (FIG. 2) so as to be displaceable. A cylinder-piston unit 31 acts on the ejector 28 to move it (FIG. 2).

Arranged parallel to the winding mandrel 12 and adjacent thereto is a holding mandrel 32 which bears a stop 33. This holding mandrel 32 is fastened to a holder designated by 34, which can be moved up and down in the direction of the arrow J. The upper end position of the mandrel 32 is limited by a stop 35. In this upper end position, the longitudinal axis of the holding mandrel 32 is aligned with the longitudinal axis of the winding mandrel 12 located in its lower end position. The drive for lifting and lowering the holder 34 in the direction of arrow J is only shown schematically and is designated by 36. By means of this drive, the holder 34 and thus also the holding mandrel 32 can be rotated about the longitudinal axis 34a of the holder 34.

A support table 37 and a knotting unit 38 are arranged below the holding mandrel 32. The latter is of a type known per se and has a knot designated 39. The knotting unit 38 corresponds in structure and effect to the knotting units as they are used in conventional strapping machines. At the knotting point 39, one end 40a of a cord 40 is held, which runs from this knotting point 39 to the winding mandrel 12, extends through its through channel 12a and extends to a cord roll 41 (FIGS. 3 to 8). At its end facing this line roller 41, the through-channel 12a is provided with a line brake 42.

A driver 43 is arranged between the winding mandrel 12 and the holding mandrel 32 and can be moved up and down in the direction of the arrow K. 2, the guide 44 for this driver 43 is shown.

The mode of operation of the described device will now be explained in more detail below with reference in particular to FIGS. 3 to 8.

The scale formation S fed by the belt conveyor 2 is fed to the winding mandrel 12 (FIG. 3) which is in the starting position. In this starting position, the line runs from the line roller 41 through the channel 12a to the knot 39. As already mentioned, the supplied scale formation S is wound up between the winding mandrel 12 and the belt 16 on the winding mandrel 12, as also mentioned, with increasing diameter of the printed product roll Winding mandrel 12 and the deflection roller 22 is raised.

Towards the end of the winding process, a wrapping element is placed under the trailing end section of the scale formation S to be wound, which, e.g. can be formed from a transparent plastic film with self-adhesive properties, as is explained in more detail in the previously mentioned DE-OS 3 330 485 and the corresponding GB-OS 2 126 188. This wrapping element is wound up with the scale formation S and surrounds the finished roll on its outside and holds it together, as is known from the two OSes mentioned. 1 and 4, a finished printed product roll 45 is shown with the wrapping element 46 holding it together. This roller 45, which is shown in broken lines in FIG. 1, still lies on the belt conveyor 3.

Now the belt conveyor 3 is moved back by means of the cylinder-piston unit 11 in the direction of arrow C into the release point designated by solid lines and 3 'in FIG. 1, which has the consequence that the finished winding lowers until the swivel arm 13 is present at the stop 15. The lower end position of the finished roll is shown in FIGS. 1, 2 and 5 and designated 45 '. In this lower end position, the longitudinal axis of the winding mandrel 12 is aligned with the longitudinal axis of the holding mandrel 32, which, as shown in FIGS. 2 and 5, assumes its upper end position in which the holder 34 abuts the stop 35. Now, by means of the cylinder-piston unit 27, the lever 25 with the deflection roller 22 is pivoted into the upper end position 25 ', 22' shown in solid lines in FIG. 1. In addition, the lever 23 together with the deflecting roller 20 is pivoted into the end position, which is also indicated by solid lines in FIG. 1 and by 22 and 20, respectively. In these end positions of the deflection rollers 22 'and 20' and the belt conveyor 3 in its release position, the belt with a solid line and designated 16 'runs from the deflection roller 19 to the belt conveyor 3', on the underside thereof and along part of the circumference of the belt lowered roller 45 'to the deflection roller 22', as can be seen from FIG. 1. With this course of the belt 16 ', it is now possible in a next step to push the lowered roller 45' onto the holding mandrel 32 by means of the ejector 28 advanced in the direction of the arrow L, as is shown in FIGS. 2 and 6 . The ejector 28 pushes the roller 45 'onto the holding mandrel 32 until the roller 45' abuts the stop 33 (position 45 ", FIGS. 2 and 6). During this displacement movement of the roller 45 'from the winding mandrel 12 onto the holding mandrel 32 takes the reel 45 'with its leading end face the cord 40 and pulls it away from the chute reel 41, as can be easily seen from Fig. 6. The cord 40 now runs from the knot 39 at which the cord end 40a is held , through the inner opening 47 of the roller 45 "and through the channel 12a in the mandrel 12.

By means of the drive 36, the holder 34 and with it the holding mandrel 32 are lowered in the direction of the arrow J until the roller 45 ″ rests on the support table 37. The roller in this position is shown in FIGS In the meantime, the belt conveyor 3 has been moved back into its operative position and the ejector 28 has been withdrawn, as shown in Fig. 7. In addition, the deflection rollers 20 and 22 are again in their position in Fig. 1 solid lines or dash-dotted starting position, so you can start forming a new role.

The entrainment member 43 is now lowered in the direction of arrow K and thereby captures the section 40 'of the cord 40' which extends between the winding mandrel 12 and the roll 45 'located on the take-up mandrel 32 and leads this cord section 40' to the knotting point 39 the end 40b of the cord section 40 'is linked to the cord end 40a in a manner known per se, the cord 40 is cut through behind the knot formed and the now free end of the cord section 40' is again held at the knot 39. Around the roll 45 " a carrying loop 48 has now been formed, which consists of a piece of cord which extends on the one hand through the inner opening 47 of the roller 45 '' and on the other hand runs around the roller 45 '' on the outside.

The roller 45 '' provided with a carrying loop 48 is now lifted off the support table 37 by lifting the holder 34 and the holding mandrel 32. The holder 34 is then rotated through 90 ° about its longitudinal axis 34a, as shown in FIG in Fig. 8 with 45 "" roller 45 can now be repelled by the mandrel 32.

As can further be seen from FIG. 8, the driver 43 has been moved upwards in the direction of the arrow K. A new roller 45 is formed on the mandrel 12 in the manner described. As shown in FIG. 3, the free end 40a of the cord 40 is held at the knot 39, from which the cord 40 runs through the channel 12a in the winding mandrel 12 to the cord roll 41. After completion, this new roller 45 is provided with a carrying loop 48 in the manner described.

9 and 10 are a perspective view of printed product rolls 45 with a carrying loop 48, which are formed by a piece of knotted cord 40. In Fig. 10 the node is designated 49. This carrying loop 48 makes it possible to handle the printed product roll 45 in a simple manner and, in particular, to carry it by hand. This strap 48 can be attached fully automatically in the manner described above and without much additional time. Since the strap 48 is formed next to the actual winding point 5, a new roll can be formed in each case, while the strap 48 is attached to the previously formed roll.

Instead of a cord 40, e.g. a plastic tape can also be used, the ends of which are connected to one another by heat sealing or welding. Instead of a knotting unit, a heat seal or welding unit is then to be provided. Otherwise, the attachment of a strap made of such a plastic band would be about the same as for a cord.

It would also be conceivable in itself to pull the finished winding 45 'from the winding mandrel 12 in that the winding 45' is not pushed away, but the winding mandrel 12 is pulled out of the finished winding 45 '. The carrying loop 48 could be formed in a similar manner to that described.
