Definitions
- the invention relates to a rotating device with which the direction of travel of flat products can be changed.
- products which can be printed sheets or higher products such as multi-page brochures or books, it is often necessary to transport them further to the original direction of rotation of 90 degrees.
- the invention has for its object to provide a turning device for products of the type mentioned, in which the direction of rotation of the products can be changed as desired, in particular can also be maintained, without the individual products in connection with change of direction must be stopped.
- This invention is given by the features of the main claim. Useful further developments of the invention are the subject of further claims following the main claim.
- the rotating device according to the invention is characterized in that the products can be transported further in any orientation without being stopped.
- the transport directions of the two transport devices can be arcuate or, in particular, linear.
- the transport directions can be aligned parallel or concentrically to one another.
- endlessly rotating conveyor belts for example in the form of toothed belts, can be used.
- the individual products can be transported lying on such conveyor belts. It would also be possible to convey products hanging or lying on top, for example by means of vacuum technology known per se.
- the transport devices can also have roller or roller conveyors on which the products can also be transported lying or hanging.
- pressure elements can be used which rest on the products. These pressure elements can be arranged in such a way that the desired torque can act on the individual products.
- the axis of rotation of the respective torque is perpendicular to the level of the transport devices. The axis of rotation can be effective next to or between the two transport devices, for example, in particular the two conveyor belts, or also on one of these transport devices.
- Balls can be used as pressure elements, which lie above the transport devices on the products in the area of the rotating device.
- Such balls can be freely rotatable.
- Such storage can be implemented in a plate arranged above the products.
- the plate can also be used to prevent a build-up in the area of the product corners that may occur when turning the individual products, such as the printed sheets.
- individual rod segments or other elements that prevent the product from rearing up at the corners or sides can also be used.
- the distance between the plate and the transport devices can be adjusted.
- FIG. 1 is a plan view of a first rotating device according to the invention for individual printed sheets, in which the printed sheets are rotated one by one without a stop by 90 degrees,
- FIG. 2 shows a representation similar to that of FIG. 1, in which the products are rotated in a manner comparable to FIG. 1, but with different transport devices compared to the rotating device according to FIG. 1,
- FIG. 3 shows a rotating device similar to that of FIG. 1, with a rotation of a printing sheet by 30 degrees
- 4 shows a change in the running direction for individual printed sheets by 90 degrees, as is known in the prior art
- 5 shows an arrangement of three product streams arranged in parallel next to one another, for example of individual printed sheets, with a corresponding triple-acting rotating device
- FIG. 6 is a schematic side view of a conveyor belt that can be used in the above rotating devices according to the invention, with a pressure element lying on the product and not rotatable in the direction of transport, designed as a ball or alternatively as a roller body,
- FIG. 7 shows a representation similar to that of FIG. 6, with a conveyor belt in which pressure elements in the form of balls, which can be rotated in the direction of transport, rest on the respective product,
- FIG. 8 is a perspective view of the inlet area of a double rotating device according to the invention, with which two printed sheets can be rotated by 90 degrees at the same time,
- FIG. 9 is a sectional view of a ball-containing plate pressing the printed sheets against the transport devices during their turning process
- Fig. 10 is an enlarged view of the plate in the region of a ball.
- a rotating device 10 has a first transport section 12 and a further transport section 14.
- the products transported through the two sections 12, 14, which in the present case are individual printed sheets 16, have a first transport direction 18 and a second transport direction 20, who are cursed in the present case.
- the individual printed sheets 16 have a rectangular shape in the present case with four corners A, B, C and D.
- the individual printed sheets 16 In the first transport section 12, the individual printed sheets 16 have a first running direction in which they lie at the front with their corners C, D in the transport direction 18.
- the individual printed sheets 16 In the second transport section 14, the individual printed sheets 16 lie in the transport direction 20 with their two corners B, C at the front.
- the individual printed sheets 16 are therefore present rotated by 90 degrees with respect to the first transport section 12 in the second transport section 14. This turning takes place in the turning device 10 provided between the two transport sections 12, 14.
- the right conveyor belt 24 has a higher speed than the left conveyor belt 22.
- the two different speeds have the effect that the point P1 present above the left conveyor belt 22 is transported further to point Pia after a certain distance. While the transport path 26 is traversed by the point P1 in a certain period of time, the point P21 present in the region of the right transport belt 24 moves along the transport path 28 into its position P21a, for example.
- the transport path 28 results from the correspondingly greater transport speed of the right one than the left conveyor belt 22.
- Conveyor belt 24 The point P22 (distance 34), which is removed from the front edge 30 of the printing sheet 16 as far as the point P1 before the rotation, migrates to its rotated position P22a during the transport path 28.
- the rotated sheet 16a can then be transported further in the second transport direction 20.
- the transport speed can be the same as that in the first transport section 12.
- These transport speeds can also be present on the left conveyor belt 22. This would then mean that the printed sheet 16 is transported into its rotated position 16a at an unchanged, constant speed.
- the resultant 38 of the transport directions 18, 20 is present parallel to the two left and right transport belts 22, 24 arranged parallel and spaced apart.
- the areas of the printing sheet 16 which act on the printing sheet 16 and cause the rotation lie in the direction 40 of the resultant 38 in the transverse direction 40 - in the illustration according to FIG. 1 - left or right next to the resultant 38, once in the area of the left conveyor belt 22 and others in the area of the right conveyor belt 24.
- the rotating device 10.2 shown in FIG. 2 differs from the rotating device 10 only in that there are three transport devices, each lying parallel to one another.
- a first transport device 22.1 acts in the center of gravity of the printed sheet 16, at the point P1.
- the point P1 is thus moved into the position Pia.
- the points P21 and P31 are pushed into their rotated positions P21a and P31a by these two conveyor belts 24.1 and 24.2, which could also only be present on their own.
- the corresponding points P22 and P32 come into their rotated positions P22a and P32a, as has already been described in comparison with FIG. 1 with the points P22, P22a.
- the two speeds of the conveyor belts 24.1 and 24.2 are different, the speed of the rightmost conveyor belt 24.2 being greater than that of the conveyor belt 24.1 arranged further to the left, corresponding to the respective greater distance from the conveyor belt 22.1. However, the speed of this conveyor belt 24.1 is greater than the speed of the left conveyor belt 22.1.
- a left boundary wall 42 is present in the transport direction before the turning action on the individual printed sheets 16, which is present in the present case on the left to the left edge 44 of the printed sheet 16.
- This left boundary wall 42 ends in the transport direction in a rounding leading away from the printed sheet 16
- This boundary wall 48 is arranged next to the edge 30 which is now on the side. It prevents an undesired further rotation of the printing sheet 16a.
- FIG. 3 shows a sheet 16 which is rotated by means of a rotating device 10.3 into a position 16b rotated in the present case by approximately 30 degrees by means of a left conveyor belt 22.3 and a right conveyor belt 24.3.
- the speed of the right conveyor belt 24.3 is correspondingly greater than that of the left conveyor belt 22.3, so that both the point P1 in its position Pia above the left conveyor belt 22.3 and a point P21 above the right conveyor belt 24.3 can be brought into its position P21a.
- point P22 of sheet 16 moves in. its position P22a in the rotated position of the arc 16b. Points P21 and P22 lie laterally next to one another in the transverse direction 40.
- the resultant 38.3 of the transport directions resulting from the transport directions of the two transport belts 22.3, 24.3 lies in the direction between the two transport belts 22.3, 24.3.
- the sheet 16b can then be transported further in the direction of the resultant 38.3 or also in a direction rotated, for example, by 30 degrees, in the transport direction 20.3, or in any other transport direction.
- the 90 degree turning station 55 shown in FIG. 4 is a device known in the prior art.
- the individual sheets 16 run in a first transport section 56 in a first transport direction 58 in this turning station 55 onto an impact wall 60, on which they are stopped. They are then transported in a transport direction 62 rotated by 90 degrees along a second transport section 64.
- the transport directions 58, 62 rotated relative to one another ensure that the orientation of the individual sheets also changes by 90 degrees.
- the individual printed sheets 16 are braked down to zero speed in the transport direction 58 in order to then be accelerated again to the desired transport speed.
- the rotary device 10.5 with an upstream spreading device 74 and a subsequent spreading device 76 is arranged between the first transport section 12.5 and the second transport section 14.5.
- the spreading device 76 returns the product flows from the mutual center distance 78 to the mutual, smaller center distance 72.
- This space-saving device takes into account that the rectangular length of the rectangular sheets is shorter than the diagonal 80 of the printing sheets in question.
- the individual printed sheets are rotated around a ball 84 placed in a plate 82 (FIG. 6).
- the plate 82 is present above the printed sheet 16, for example, and also above the left conveyor belt 22 (FIG. 1).
- the ball 84 is by means of the plate 82 of pressed on top of the printed sheet 16 and thereby pressed the printed sheet 16 from above against the conveyor belt 22.
- the printed sheet 16 thus has the transport speed 86 of the upper run of the endlessly rotating conveyor belt 22 in the region of the ball 84. In relation to FIG. 1, the ball 84 is thus at point P1 on the printed sheet 16.
- the ball 84 is also transported together with the plate 82 holding it in position at the transport speed 86 of the conveyor belt 22 (FIG. 7). As a result, the point P1 reaches its position Pia (FIG. 1). Instead of the ball 84, a roller-shaped body 88 (FIG. 6) could also be used.
- the transport speed of the sheet 16 in the area of the left conveyor belt 22 could be braked by not completely fixing the ball 84 in the transport direction. This would have the consequence that the axis of rotation for the sheet 16 - based on FIG. 1 - would move to the left of the left conveyor belt 22.
- the swivel radius of the printed sheet 16 would increase - based on FIG. 1.
- the conveyor belts can also be realized by driven shafts arranged in parallel one behind the other.
- rollers or other devices which press or suck the product against the conveying devices could also be used, as will be described in more detail below in connection with FIGS. 8 and 9.
- the left conveyor belt 22.1 could also act on the printing sheet 16 not from below but from above, so that the individual sheets would be transported hanging on the left conveyor belt 22.1.
- the individual printed sheets would be transferred from conveyor belts arranged one behind the other to a conveyor belt 22.1 designed as a suction belt.
- the sheet 16a rotated for example by 90 degrees, would then be thrown back onto a conveyor belt.
- the rotating device 10.2 one or both of the conveyor belts 24.1, 24.2 exerting the torque on the sheet could still be present as described.
- Both the transport devices and the devices for generating the necessary thrust on the products can therefore be made from different ones Apply directions to each sheet.
- the products can have any shape, they do not have to be rectangular, for example.
- FIG. 8 shows a double rotating device 10.8 in which two printed sheets 16.8, 16.9 can be rotated through 90 degrees simultaneously. The turning process for both printed sheets takes place independently of one another.
- the printed sheets 16.8, 16.9 fed to the double rotating device 10.8 are moved away from one another in a spreading device 74.8, as is mentioned in connection with the rotating device 10.5 with the printed sheets 16.1 and 16.3 described therein.
- the spreading device 74.8 has a left upper and lower cord-like conveyor belt 95.1 and 95.2, as well as a right upper and lower cord-like conveyor belt 95.3 and 95.4 which is also identical to it.
- the two upper conveyor belts 95.1 and 95.3 run endlessly over a front and rear roller 96, 97.
- the lower conveyor belts 95.2, 95.4 present under these conveyor belts 95.1, 95.3 likewise run endlessly about a front and rear roller 98, 99.
- the two front rollers 96, 98 and the rear two rollers 97, 99 have such an equal center distance 100 that the printed sheets 16.8, 16.9 conveyed between the respective upper and lower axes subsequently follow by means of the cord-like conveyor belts 95.1, 95.2, 95.3 and 95.4 Leave the spreading device 74.8 at a mutual distance 102.
- This distance 102 is so large that after turning the two printed sheets 16.8, 16.9 there is still a clear distance 104 between them in the transverse direction 40.
- Each of the two conveyor belts 22.8 and 24.8 present in the double rotating device 10.8 - in the present example - lie parallel next to one another.
- One of the two conveyor belts, in this case the conveyor belt 24.8, runs faster than the other conveyor belt 22.8.
- the sheet 16.8 and in the same way also the sheet 16.9 are rotated by 90 degrees, as is described in principle in connection with the rotating devices described above.
- the two conveyor belts 22.8 and 24.8 are perforated.
- the holes 110 passing through them are connected to a vacuum channel 112 provided longitudinally under the conveyor belt 22.8, which is present in a support plate 114 and is connected to a vacuum source, not shown in the drawing. Except for an upper longitudinal slot, which is covered from above by the relevant conveyor belt, the vacuum channel 112 has a closed cross section.
- a single support plate 114 between two side frame walls 116, 118 of a frame 120 is present.
- this support plate 114 there are four vacuum channels 112 corresponding to the number of conveyor belts, all of which are connected to a vacuum source. Each vacuum channel lies exactly under a conveyor belt.
- the support plate 114 is covered from above by a press plate 130, which covers the four conveyor belts from above.
- Balls 84.9 are arranged in a row one behind the other in this press plate 130, as has already been described in principle in FIG. 7. Due to their own weight, these balls rest on the conveyor belts 22.8, 24.8 from above. If a printed sheet 16.8, 16.9 rests on the conveyor belts, they lie on the respective printed sheet 16.8, 16.9 from above and hold it on the conveyor belts from above.
- the balls 84.9 are individually rotatable in a pot-like holder 132.
- the holder 132 is present in an opening 134 of the press plate 130 from above.
- the opening 134 has a different stepped bore 136, so that the holder 132 is seated on a corresponding shoulder 138 running around at the bottom.
- the holder 132 can be pulled up out of its respective opening 134.
- the lower edge 140 of the holder 132 can be bent up elastically and the ball 84.9 seated in the holder 132 can thereby be removed.
- balls 84.9 are thus freely rotatable over all existing conveyor belts 22.8, 24.8 rotating a printed sheet 16.8 or 16.9.
- the respective printed sheet 16.8, 16.9 sucked in from above by means of the balls 84.9 on the conveyor belts 22.8, 24.8 is pressed between the balls 84.9 and the conveyor belts 22.8, 24.8 transporting it in such a way that it is still rotatable between the balls 84.9 and conveyor belts 22.8, 24.8 is.
- the him from above and The force pressing in at the bottom is only so great that sufficient friction is built up on the conveyor belts, by means of which it can be rotated - in the present case by 90 degrees.
- the balls 84.9 also prevent the sheet from moving upwards away from the conveyor belts during this rotational movement and thus losing its hold on the conveyor belts. If the printed sheets are sufficiently rigid, the balls 84.9 could also be dispensed with and the turning process could be carried out using suction belts alone or only with conveyor belts - without the assistance of suction forces. It is only important in the case of the rotating devices according to the invention that a sufficiently large frictional force is generated in order to set the printing sheets into a rotary movement within a rotating plane by means of the conveyor belts driven at different speeds, which is aligned parallel to the transport plane receiving the conveyor devices, such as the conveyor belts.
- a device which is structurally comparable to the expanding device 74.8 can be provided, by means of which the rotated printed sheets can be transferred to a subsequent transport device at any distance from one another in the transverse direction.
- the running direction of its cord-like conveyor belts is aligned more or less obliquely in this device in the outlet.
