Description

  • The invention relates to a device for aligning, by means of a paddle wheel, onto a delivery belt arranged below it in the form of a scale web, curved products, in particular folded products.
  • A known arrangement of this type consists of gripper chains engaging in a rake shape in the bucket wheel, the grippers of which grasp the products located in the bucket wheel compartments on their front edge. The gripper chains run at a reduced speed compared to the effective circumferential speed of the paddle wheel, so that the products gripped by the grippers are lifted out of the paddle wheel compartments and placed on the delivery belt underneath. With a device of this type it is possible to even out the product distance on the delivery belt. However, the known arrangement proves not only to be very maintenance-intensive, but also to be very susceptible to faults, since the grippers and gripper chains used here are very sensitive parts. In addition, the gripper chains engaging between two bucket wheel disks require a comparatively large distance between these bucket wheel disks. The disadvantage here is that the products accommodated in the paddlewheel compartments are without support in the areas left free for the gripper chains and can therefore be bulged out due to the centrifugal forces acting on them, which not only leads to difficulties in the takeover by the grippers of the gripper chains, but also to Inaccuracies in the filing can result. The known arrangement therefore proves to be not simple and reliable enough.
  • Proceeding from this, it is therefore the object of the present invention, while avoiding the disadvantages of the known arrangements, to provide a device of the type mentioned at the outset which is not only simple in construction and easy to maintain, but also ensures high operational reliability in robust operating conditions and which nevertheless ensures high placement accuracy.
  • According to the invention, this object is achieved in a surprisingly simple manner by using at least one driver which is driven at an advance compared to the transport speed of the products and which engages with the rear edge in the transport direction of the last product which is placed on the delivery belt with its front edge, at least its movement path in some areas runs out of the transport level defined by the delivery conveyor.
  • To form the catches, stop edges can be provided which are fixedly arranged on an associated support and which have no movable parts requiring control and which therefore can advantageously not be subject to any malfunction. The attack on the rear edge of the respectively assigned product is advantageously ended here simply by the fact that the driver movement path preferably runs downward from the transport plane of the products, which results in simple self-control. The arrangement according to the invention, which in an advantageous manner works practically maintenance-free over long periods of time, also proves to be particularly simple and clear. Since the products placed on the delivery belt are aligned from their rear edge, the drivers do not come into engagement with the paddle wheel. It is therefore advantageously possible to support the products in the region of the paddle wheel over a comparatively large width, as a result of which damage to the products and / or malfunctions or inaccuracies when depositing is effectively prevented. The advantages that can be achieved with the invention can thus be seen in particular in excellent reliability with little structural complexity and thus in excellent economy.
  • According to an expedient embodiment of the superordinate measures, the driver (s) can be designed as peripheral cams of at least one uniformly driven cam carrier, preferably formed by a belt running over deflection rollers. These measures enable a simple drive to manage the movement of the drivers. The use of a cam band advantageously enables a comparatively long engagement along a practically straight cam track, which ensures reliable alignment. In this case, two or more parallel cam carriers can expediently be provided, the cams of which are aligned with one another transversely to the direction of movement. These measures advantageously ensure that the alignment forces acting on the products can be introduced at different, comparatively far apart points, which means that reliable alignment can be expected.
  • A further expedient embodiment of the superordinate measures can consist in the fact that the delivery belt consists of several individual belts spaced apart from one another, between which the driver (s) is or are passed in a rake-like manner. The drivers do not come out of engagement with the respectively assigned rear edge of the product until the entire product lies on the delivery belt, which allows high accuracy to be expected.
  • The belts forming the cam carriers, preferably engaging between the individual belts of the delivery belt, can advantageously be against be arranged so as to rise above the delivery belt against the transport direction. These measures result in an adaptation to the circumference of the paddle wheel and thus ensure that the rear edges of the products are caught near the paddle wheel by the belts designed as cam carriers, thus preventing malfunctions.
  • According to a further advantageous embodiment of the superordinate measures, the driver or drivers can be adjustable forwards and backwards in the direction of travel. This measure enables a precise adjustment of the time of the intervention and thus ensures a reliable alignment.
  • A further development of the superordinate measures can consist in the fact that at least one lifting belt engaging in the bucket wheel above the delivery belt and provided with the same speed as the delivery belt is provided, which with the delivery belt includes a wedge space tapering in the running direction, the narrowest cross-section of the area the intersection between the carrier movement path and the delivery belt transport plane is approximately an amount corresponding to the format length. This ensures that the drivers disengage from the rear edge of the assigned product as soon as it is grasped with its front edge in the region of the gap between the delivery belt and the lifting belt and is therefore subjected to positive guidance.
  • Further expedient further developments and advantageous refinements of the superordinate measures result from the following description of an exemplary embodiment with reference to the drawing in conjunction with the remaining subclaims.
  • The drawing shows a side view of a paddle wheel delivery with an alignment device formed by cam belts in a schematic representation.
  • The delivery device shown in the drawing, which may be arranged downstream of a folder attached to a printing press, consists of a paddle wheel 1 which is arranged above a delivery belt 2 leading to a further processing station, for example to a package delivery or the like. The paddle wheel is loaded with curved products 4 folded here by a band guide 3 ending above it. The products 4 released by the belt guide 3 shoot from above into the compartments 6 provided between the blades 5 of the blade wheel 1 and are deposited on the delivery belt 2 in the form of a scale track 7 after about a quarter turn. In order to lift the products 4 out of the compartments 6, parallel lifting belts 8 are provided above the delivery belt 2 in a rake-like manner which engages in the paddle wheel 1 formed by a plurality of disks arranged at a corresponding distance from one another. The lifting belts 8 are comparatively narrow, so that the distance between the disks forming the paddle wheel can be comparatively small.
  • In normal paddle wheel delivery, products 4 fall out of the paddle wheel compartments 6 in an uncontrolled manner onto the delivery belt 2 located underneath. It is therefore not possible here for exact product spacing tolerances, i. H. to maintain an exact scale spacing. On the other hand, however, with increasing machine speeds, the requirements for the accuracy of the scale spacing become ever greater, since this is the only way to ensure smooth takeover of the product flow by cycle grippers in the area of downstream units, such as a package delivery arm.
  • The products 4 arriving on the delivery belt 2 are therefore adjusted so that at their rear end engaging drivers 9, which are moved ahead of the normal transport speed of the products 4 given by the delivery belt 2, ensure that an exact alignment and an exact scale distance are ensured are. The drivers 9 are received on an endless, uniformly driven carrier 10, from which the product ends which come into engagement with the drivers 9 are caught and supported by the paddle wheel 1 after their release. The path of the drivers 9 crosses the transport plane defined by the delivery belt 2 from top to bottom, so that the drivers 9 dive from a certain point below the transport plane of the delivery belt 2 and thus automatically come out of engagement with the respectively assigned product end 4a. The drivers 9 are adjusted so that they only run onto the rear edge of the associated product when its front end is released by the paddle wheel 1.
  • To accomplish a clean product stop, each driver 9 consists of two or more cams 11 which are arranged next to one another at a distance and have aligned driver edges, each of which is assigned a cam carrier arranged at a corresponding distance from one another. In the exemplary embodiment shown, the carriers 10 assigned to the drivers 9 are designed as belts running over uniformly driven deflection rollers 12, the circumference of which is occupied by a plurality of cams 11 each having the same distance from one another. This results in an elongated, straight driver movement path. In order to bring about a reliable takeover of the products 4 by the delivery belt 2, its rear end is toothed with the front end of the belts forming the carrier carriers 10 here. For this purpose, the delivery belt 2 consists of a plurality of individual belts arranged next to one another at a distance and running over deflection rollers 13, between which the front end in the transport direction of the belts acting here as carrier carrier 10 engages in a rake-like manner. The in transportation Direction rear pulleys 13 of the single belt forming the delivery belt 2 are mounted on pivoting levers 14 which are pivotable to adjust the belt tension.
  • The belts acting as carrier carriers 10 are arranged inclined relative to the delivery belt 2 in such a way that their upper run rises in the opposite direction to the transport direction relative to the delivery belt 2 in accordance with the curvature of the paddle wheel 1, thus ensuring that the product ends 4a reaching the belts forming the carrier carrier 10 are close to the bucket wheel be intercepted and therefore do not have to travel a long distance. The circumferential area of the impeller 1, which rises further towards the direction of rotation compared to the slanting belts forming the inclined carrier 10, is encompassed by a guide plate 15, the lower end of which overlaps the rear deflection rollers 12 of the entraining carrier 10 in the transport direction and thus practically overlaps the increasing region of the entraining motion path, so that the product ends sliding over this guide plate 15 are reliably received on the carrier carriers 10 and come into clean engagement with the carriers 9. The toothing between the carrier 9 and the delivery belt 2 is so large that the upper run of the belts forming the carrier carrier 10 crosses the delivery belt 2 or its individual belts in the region of its straight line, thereby ensuring that the drivers 9 emerge from the transport plane of the delivery belt 2 gently disengage from the assigned product rear edge. The inclination of the belts acting as carrier carriers 10 can be adjusted, whereby the position of the exchange area of the carriers 9 from the transport plane of the delivery belt 2 can be adjusted. For this purpose, the deflection rollers 12 assigned to the belts acting as carrier carriers 10 can simply be pivoted, as indicated by the arrows 16. The front and rear deflection rollers 12 are expediently pivoted about an axis of rotation located approximately in the middle of the band, so that the desired orientation of the bands acting as carrier carrier 10 with respect to the impeller 1 is maintained.
  • The drivers 9 can be moved back and forth in the direction of travel to ensure trouble-free operation. For this purpose, in the exemplary embodiment shown, the belts acting as carrier carriers 10 can simply be adjusted forwards and backwards in the running direction. This can be accomplished simply by providing in the drive chain hoist the uniformly driven, belt-receiving deflection pulleys 12, intermeshing, helically toothed spur gears, which are arranged laterally displaceable relative to one another. Another embodiment can consist in that an axially adjustable spline shaft with twisted teeth is provided in the drive chain hoist. With this type, particularly long travel ranges can be achieved.
  • The lifting belts 8 which engage in the blade wheel 1 in a rake-like manner are arranged such that their lower run associated with the delivery belt 2 includes a wedge space 17 which tapers in the transport direction, so that the products resting on the delivery belt 2 come into contact with in the area of the largest cross-sectional constriction the lifting belts 8 come and are pressed by them onto the delivery belt 2 or its individual belts and are thus subjected to a forced transport. The belts which act here as carrier carriers 10 are inclined so that the path of movement of the carriers 9 crosses the transport plane of the delivery belt 2 in such a way that the carriers 9 come out of engagement with the rear edge of the product as soon as the front edge of this product is in the area of the tip of the wedge space 17 is gripped by the lifting belts 8, thereby reliably avoiding any constraining forces acting on the products. The passage cross-section in the area of the greatest cross-sectional constriction of the wedge space 17 is expediently adjustable in adaptation to the product thickness processed in each case. For this purpose, the deflection rollers 18 assigned to the lifting belts 8 and arranged in the area of the greatest cross-sectional constriction of the wedge space 17 can be pivoted about the axis of the impeller 1, as indicated by the arrow 19.
  • Although a preferred exemplary embodiment of the invention has been explained in more detail above, this is not intended to imply any limitation. Rather, a number of options are available to the person skilled in the art to adapt the general idea of the solution according to the invention to the circumstances of the individual case. For example, rollers arranged next to one another, preferably cut with the delivery belt 2, could also be provided as carrier carriers.
