Definitions

  • the invention is based on a device with the aid of which flat non-dimensionally stable objects can be combined into stacks.
  • An example of such products are diapers, which are not dimensionally stable due to their composition.
  • Such products are produced in a manufacturing machine and delivered by this machine so that they are transported in their own longitudinal direction. Even objects that are flat, but have no longitudinal direction, are transported so that the transport direction is parallel to the flat side. This should also be understood by transport in the longitudinal direction.
  • a device for forming stacks of this type is already known (US Pat. EP 11 48 014 ), in which the successively brought up objects are braked in a transfer device and then moved transversely.
  • the transfer device contains individual pockets, each with two side walls, which are arranged at a fixed angle of about 30 degrees.
  • the objects hit an obliquely arranged side wall, where they slide off with their front edge, to a standstill.
  • the object of the invention is to provide a device for forming stacks of flat objects which, while retaining the advantages of known devices, enables an increased output performance even with unstable products.
  • the invention proposes a device having the features of claim 1. Further developments of the invention are the subject of dependent claims.
  • the individual products delivered in a row are picked up by the transfer facility. This recording can already be done at a distance before the line-up. Then the products pass by means of the transfer device to the line-up device, where they are aligned in parallel. In this parallel orientation, the products can already be arranged in the compartments of the row of compartments. Due to the possible distance between the location of the recording in the transfer device and the line-up device is a certain distance available, within which the products can be braked.
  • the deceleration can for example be done by the products lie with their flat sides against a moving at a lower speed counter element. It is therefore not a deceleration at the front edge in the transport direction, which could lead to the compression, but by a flat deceleration along a large part of the flat side.
  • the transfer device is designed such that it gives the products a speed component in the direction of movement of the specialist series. This also makes the transition between the two directions of movement is made more gradual, so that here too the risk of unwanted deformation is reduced to eliminated.
  • the transfer device can have pockets for receiving a respective product in a development of the invention, these pockets preferably being moved at a constant speed which is less than the transport speed of the products.
  • the pockets change their shape before and / or after the reception of each product, for example, enlarge their opening and then reduce it again. This facilitates the launching of the products.
  • the possibility of Deceleration optionally also improved on both flat sides of the products.
  • each pocket has two parallel to at an acute angle extending side walls, of which each side wall is common to two adjacent pockets.
  • This makes it possible to bring the pockets closer to each other, so that it is possible to process the products to be treated with a smaller distance in the transport direction.
  • This possibility is further facilitated by the fact that these two side walls can be slightly moved apart to enlarge the opening immediately before shooting the product. For this purpose, it is sufficient to swivel the rear side wall in the transport direction. When swinging back the product is then pressed against the other side wall, which can even lead to a deceleration.
  • the pockets or their side walls of the transfer device are preferably mounted in a further development of the invention on a rotating gear means, such as a closed chain or a closed belt.
  • a rotating gear means such as a closed chain or a closed belt.
  • Other types of guidance along a closed path are also possible, for example rails with individual elements guided on the rails.
  • the side walls may for example be rigidly attached to the revolving gear means.
  • the gear means may for example be guided over a roller, which thereby forms two sections extending at a shallow angle portions of the transmission means.
  • transitioning over this role or Deflection point is pivoted to the transmission means firmly connected side wall.
  • other means are possible, such as cam followers or similar devices.
  • the line-up device can have a stop for the front edge in the transport direction of the products. At this stop the products will hit at a very low speed, with full correct zero speed adjustment. There is no longer any danger of the products compressing.
  • This stop can be arranged fixed, for example, in development of the invention. Since the speed of transport in the direction of the stack, in contrast to transport in the direction of transport of the products, is carried out at a very low speed, there is no risk of deformation of the products when they touch the stop when the products are moved along the stop. However, it is also possible and is within the scope of the invention that the stop is moved along with the row of subjects.
  • the stopper may also be formed by a part of the tray of the tray.
  • the compartments in the row of compartments may be formed between two compartment walls, which may be smaller in vertical direction than the products, so that the further transport of the transfer device pockets will not interfere with the transverse movement of the compartments.
  • the compartment which has just been loaded by the transfer device passes through Swiveling open a compartment wall and then closed again.
  • the rear compartment wall is preferably pivoted in the direction of movement of the row of subjects.
  • the compartments or the compartment walls forming them are attached to a revolving gear means, preferably fixedly mounted.
  • the revolving gear means may, for example, again be a chain.
  • this chain may have a small deflection, which then feels because of the deviation of the course of the chain from the straight line to a pivoting of the corresponding compartment wall.
  • the object When the object is pushed into the compartment, the object is braked flat on the basis of the movement component in the direction of movement of the compartments either on the immediately adjacent compartment wall, or else on the object introduced immediately before.
  • the combination of movement component in the direction of movement of the subjects and concerns on the compartment wall leads to a flat concern and thus flat braking of the individual objects over the entire extent of the objects in the longitudinal direction, ie over a maximum possible path.
  • the insertion of the objects can be done, for example, so that the objects are horizontally or horizontally moved horizontally standing, in which case they are then also moved horizontally by the subjects with their flat side ahead.
  • the axes of the chain or pulleys around which the revolving gear means passes are vertical.
  • the axes of the sprockets are horizontal and at the same height.
  • the objects can be inserted from above and then also pushed horizontally with their flat sides ahead.
  • FIG. 2 shows how individual products 1 between two conveyor belts 2 are transported zoomed up.
  • the two conveyor belts 2 run so that they hold the items 1 between them and transported in the drawing upwards. You can do that FIG. 2 can be seen that the individual products 1 are transported at a very small distance from each other in a longitudinal direction.
  • the device proposed by the invention includes a transfer device 4, which has individual pockets 5. Each pocket 5 is formed by two side walls 6. Each side wall 6 forms the separation between two pockets 5, thus belongs to both adjacent pockets 5.
  • the side walls 6 forming the pockets 5 are rigidly attached to a revolving gear means 7, for example a chain.
  • the chain passes over two pulleys 8, of which at least one is driven by a drive. This in FIG. 1 left strand 9 of this chain is rectilinear, while the right strand is guided over a guide roller 10 which is offset from a straight connection of the tangent to the two guide rollers 8 to the outside.
  • the rotating gear means 7 of the transfer device 4 runs at a constant speed.
  • the products 1 contained in the pockets 5 are now inserted into compartments 11 of a number of compartments.
  • the compartments 11 are through formed two parallel compartment walls 12 which are rigidly attached to a further rotating gear means 13.
  • the rotating gear means runs along a rectilinear path.
  • the compartment walls 12 thus run parallel to each other there.
  • Only the immediately following compartment, which is being fed by the transfer device, the following compartment wall 12a is pivoted to the opening of the compartment to the rear.
  • the object 1 inserted into this compartment instantaneously slides on the compartment wall 12b. This leads to its gradual deceleration, without it being exerted on the leading edge 14 of the product 1 a compressive force.
  • the then each next item that is introduced into the same compartment then lies flat against the respective previous item 1 and is also braked along its flat side in this way. There is no danger that the object will be compressed.
  • each compartment 11 depending on the embodiment, either one or more objects are inserted. This makes it possible to form stacks which, after being pushed out of the compartments, already have their final height.
  • the correct alignment of the products 1 in the compartments 11 is ensured by a stop rail 15 which is located above and / or below the compartment walls 12 immediately in front of the revolving gear means 13.
  • the stop rail 15 may be formed fixed. The transverse speed of the products with respect to the stop 15 is small in comparison to the speed of the products 1 in the transport direction, so that there is no risk of damage here.
  • the revolving gear means 13 for transporting the compartment walls 12 and thus the fan 11 can be driven continuously at a constant speed.
  • the compartment walls 12 may be arranged over the entire length of the transmission means 13.
  • a number of compartments 11 is filled with products 1, then such a stack, for example, with respect to the drawing plane, which is a horizontal plane, upwards, downwards, or even pushed forward. If a stack of products is made up of several compartments, then this stack can still be compressed afterwards.
  • the deflection point which is formed by the roller 10, is preferably formed at the point where the compartment walls 12 end.
  • the distance between the deflection point 10 and the stop 15 corresponds approximately to the dimension measured in the same direction of the products 1 to be stacked.
  • the transport direction of the rotating gear means 7 of the transfer device extends in the region in which the products are arranged individually for transfer, obliquely relative to the compartment walls 12 and thus the subjects 11. This means that the products 1 is already superimposed on this point of a cross-speed, which is adapted to the speed of movement of the compartments 11.
  • the objects of several compartments can be pushed out on the Ausschiebeseite simultaneously, so that they give the required overall formation.
  • compartment side walls 12 are not pivoted, but are guided parallel to each other.
  • the drawing planes of the Figures 1 and 2 should, as already mentioned, be horizontal planes.
  • the objects 1 are thus moved horizontally horizontally in the direction of the arrow 3 into the compartments 11.
  • the compartments are then also moved horizontally, the flat sides of the objects 1 are directed in the direction of movement forward.
  • FIG. 1 A facility like those in FIG. 1 is shown, but can also be arranged so that the axes of rotation of the two pulleys around which the gear means 13 is guided around, run horizontally. In this case, of course, the insertion of the articles 1 does not take place, as in FIG. 1 seems to be on the lower side but above. The objects 1 are thus brought from above, braked by the transfer device 4 and introduced into the compartments 11. The pushing out can then be done forward or backward.
  • the axes of rotation of the two guide wheels leading the gear means 13 could be arranged horizontally one above the other. Then the flat lying objects 1 are pushed horizontally and lifted upwards.
  • FIG. 3 shows a side view of an arrangement in which a rotating transmission means 13 by three Deflection wheels 19 is guided around.
  • the three guide wheels 19 have horizontally and mutually parallel axes of rotation 20.
  • the arranged on the outside of the transmission means 13 compartment walls 12 are thus moved in rotation of the guide wheels 19 in the direction shown on the right section upwards, then at rotation on the arc of Gear means 13 deflected and are then moved horizontally from right to left.
  • the products 1, the in FIG. 3 are not shown, are conveyed lying flat and in a similar manner as in the arrangement of FIG. 1 , inserted into the compartment 11 formed between the compartment walls 12.
  • the products can then slip again, if they have not reached the inner edge in previous working steps.
  • the top of the product can then be ejected, for example, up, back or forward. Since here too the products can protrude beyond the compartment walls 12 to the front and to the rear relative to the plane of the drawing, one can attack at these points in order to convey the products out as stacks.
