Definitions

  • the invention relates to a delivery device with at least one transport path that defines a transport plane that engages under a paddle wheel and that receives the products deposited on it by the paddle wheel, in particular in the form of a shingled stream.
  • At least one web is provided which is aligned in the delivery direction, is raised in relation to the transport plane on the transport plane, has a sloping in the delivery direction and enters the front end into the transport band-side transport plane.
  • the products leaving the paddlewheel first come into contact with the narrow paddlewheel-side cold of the web and in doing so receive practically a bend running in the delivery direction, which stabilizes the products and ensures exact guidance of the products along the web running in the delivery direction.
  • a so-called floating of the products i. H. a sliding of the products on an air cushion prevented, so that an exact positioning of the products is achieved not only transversely to the direction of delivery, but also in the direction of delivery.
  • a bridge arranged in the middle can be provided. This practically results in a strong central beading of the products and therefore, despite little effort, particularly precise positioning.
  • Another expedient measure can be that the inclination of the web edge is adjustable. This measure enables an exact adjustment of the position of the upper web edge to the respective product length or product thickness.
  • a particularly advantageous embodiment of the superordinate measures can consist in the fact that the central region of the web at least touches the outer circumference of the impeller, preferably in the outer circumference of the impeller rads engages. This measure ensures that the web is already in action while the products are still in the paddle wheel. The products are practically pressed against the web by the blades adjacent to the web, which ensures high accuracy both in the direction of delivery and transversely to it.
  • the web can be designed as an upper run of a preferably driven belt belt deflected from two to the front relative to the transport plane on the transport plane from the rear to the front.
  • the web can be designed as an upper run of a preferably driven belt belt deflected from two to the front relative to the transport plane on the transport plane from the rear to the front.
  • these measures enable a particularly simple and maintenance-friendly outlay, since no sliding coatings, etc. are required and since, due to the lack of relative movement of the products relative to the web, low-wear operation is also guaranteed.
  • a further expedient measure can consist in that the belt belt is driven with a surface speed that is about 1% to 5% lower than the conveyor belt or the conveyor belts, which experience has shown can have a positive effect on the securing and exact positioning of the products.
  • the belt belt can be flanked by at least two conveyor belts, the conveyor belts and the belt belt are guided around a common front drive roller, preferably provided with a recess assigned to the belt belt, and the belt belt is assigned a rear deflection roller which is independent of the rear deflection members assigned to the conveyor belts and whose diameter is larger than the diameter of the drive roller.
  • the delivery device on which the figures are based consists of conveyor belts 2 which run in the delivery direction and pass a distance below a paddle wheel 1.
  • conveyor belts 2 which run in the delivery direction and pass a distance below a paddle wheel 1.
  • these are, as can best be seen from FIG. 2, two comparatively wide, with a small mean distance next to one another arranged flat conveyor belts, which are arranged at least on the upper run side in a plane and whose surface facing the paddle wheel 1 accordingly defines a transport plane.
  • the conveyor belts 2 are unguided by front and rear deflection members in the direction of delivery.
  • a deflecting roller 4 is provided which is continuous over the machine width and is coupled to a drive shaft 3.
  • deflection drums 6 which are freely rotatably supported are provided on an axis 5 which is continuous over the width of both conveyor belts 2.
  • the effective diameter of the driven, front deflection roller 4 and the rear deflection drums 6 is approximately the same, so that the lower run of the conveyor belts 2 runs parallel to the associated upper run.
  • the front deflecting roller 4 is rotatably mounted on the frame side walls 7 via the drive shaft 3 and a bearing pin opposite this.
  • the axis 5 assigned to the rear deflection drums 6 engages with lateral flat pins in slots in lateral bearing straps 8 which are clamped onto a cross member 9 fastened to the frame side walls 7.
  • the distance of the transport plane defined by the conveyor belts 2 from the circumference of the paddlewheel can be adjusted by rotating the bearing straps 8 with respect to the traverse 9.
  • the flat pins of the axis 5 receiving the rear deflection drums 6 are supported by setscrews 10 on the bearing straps 8.
  • the axis 5 is supported not only on the lateral bearing brackets 8 but also on a central bearing bracket 8a, which is also clamped onto the crossbeam 9, in order to avoid excessive deflection.
  • the upper web edge falls from behind in the delivery direction to the front and at its front end in the transport plane runs in, as Figure 1 clearly shows.
  • a web 11 arranged in the middle is provided.
  • the upper edge of the web 11 on the impeller side has a straight, linearly descending course.
  • the folded products to be deposited by the paddle wheel 1 onto the conveyor belts 2 in the form of a scale track are kinked or corrugated by the web 11 which is raised compared to the conveyor belts 2 and thus stabilized with regard to their position.
  • the decreasing height distance in the cantilever direction from the upper edge of the web 11 having the transport plane 2 defined by the transport belts 2 can run past the paddle wheel 1 at a short distance, in any case less than the transport belts 2, or can affect the paddle wheel 1.
  • the web 11 engages with its upper edge in the impeller, i. H. between two disks of the impeller 1 formed by blades, so that the products to be deposited by the impeller are pressed against the web 11.
  • the increasing backward height of the top edge of the web, i.e. H. the inclination with respect to the transport level can be adjusted so that gentle handling of the products can be achieved even when processing different products.
  • the web 11 can be designed as a fixed tongue provided with a sliding support, for example in the form of a sheet metal strip or pipe bracket.
  • the web 11 is formed by the upper run of a narrow, tensioned belt band 12 which runs from the rear to the front and is guided over two deflection members.
  • the belt band 12 can be designed as a narrow flat belt, as a V-belt or as a rope or the like. In any case, there is a web 11 with an elastically resilient upper edge, which can be very beneficial for the protection of the products.
  • the belt band 12 is designed as a circulating belt, so that relative movements between the products and the web forming the upper run of the belt band 12 are largely eliminated.
  • the belt band 12 forming the web 11 is provided with a positive drive, so that a continuous movement and thus particularly gentle operation are ensured.
  • the belt belt 12 forming the web 11 is thus driven at a surface speed which is approximately 1% to 5% below the surface speed of the conveyor belts 2, which, based on experience, ensures a particularly exact positioning of the products on the conveyor belts 2.
  • the belt belt 12 is in the illustrated embodiment in the area of the front, in the transport plane of the conveyor belts 2 cutting end around the continuous conveyor roller 4 assigned to the two conveyor belts 2, so that there is a clean entry of the web edge into the belt-side transport plane and an automatic Drive the belt band 12 forming the web 11 result.
  • the deflection roller 4 can simply be provided with an entry assigned to the belt belt 12.
  • the belt band 12 is guided around a deflection roller 13 which is independent of the deflection drums 6 assigned to the conveyor belts 2 and whose diameter is so much larger than the diameter of the front deflection roller 4 and which is arranged such that the desired one is from behind the forward slope of the upper run of the belt band 12 forming the web 11 results in that, at the same time, even in the event of a height adjustment of the deflection roller 13, collisions of the lower run of the belt band 12 with components that are continuous over the machine width, such as, for example, the traverse 9 or the axis 5, are avoided.
  • the deflection roller 13 has approximately twice the diameter of the front deflection roller 4 or the deflection drum 6.
  • the height of the deflection roller 13 is chosen so that in an intermediate position both the upper run running from its circumference and that on its circumference rising run of the Belt belt 12 runs out from the plane of the upper or lower run of the conveyor belts 2 with increasing distance from the front to the rear, which allows the inclination of the upper run of the belt belt 12 forming the web 11 to be freely adjusted.
  • the deflection roller 13 is arranged in the region behind the rear deflection drums 6 assigned to the conveyor belts 2, which results in good accessibility of the deflection roller 13 and thus a simple structure and a comparatively large web length.
  • the deflection roller 13 is freely rotatably mounted on an axis 14 parallel to the axis 5 receiving the rear deflection drums 6 of the conveyor belts 2 and is fastened on a holder 15 which can be pivoted about an axis parallel to the axis Swivel arm formed, which is clamped on a rod 16, the ends of which are rotatably mounted with their ends in extensions of the bearing brackets 8 projecting beyond the axis 5 and is pivotable by means of a clamped actuating arm 18.
  • an adjusting spindle 20 is provided which is in threaded engagement with a pin 19 rotatably received on the swivel arm 18 and which can be actuated by means of a handwheel and which is supported on a bearing block 21 fastened to the adjacent holding bracket.
  • the rod 16 By rotating the adjusting spindle 20, the rod 16 can be pivoted and the axis 14 receiving the deflection roller 13 can be raised more or less.
  • the resultant change in the length of the belt band 12 lies in the elastic range of the band material.
  • the pitch of the thread of the threaded spindle 20 can be chosen so that self-locking is guaranteed. However, it would also be conceivable to provide a locking pin, etc., assigned to the threaded spindle (20) in order to secure the set web position.
