Definitions

  • the invention relates to a turning device for turning objects, with a turning station and a conveyor belt arranged laterally next to it at a distance, the turning station being formed by two turning belts that grip and transport the object on both sides in the form of cross belts, and wherein the turning device is arranged to be movable, in particular a turning device for turning printed matter such as books or the like.
  • the books coming from the printer are in the form of so-called double-use, i.e. two books that have already been glued and have spines on them form an integrated unit, and it is therefore necessary to separate or cut this unit in order to make two out of the double-use to obtain individual books - called single-use.
  • the individual blanks can then be fed to a three-knife cutting machine, where the front, the head (upper side) and the foot (lower side) are finally cut in a known manner in order to obtain the finished book.
  • each of the two books with the same page - for example the title page - lies upwards and that the visible page on top of each book is aligned in the same way.
  • the double benefit from the printer has a form with the front page of one book at the top and the other book at the bottom.
  • the two books can lie head to head, head to foot or foot to foot. With the exception of the head-to-toe arrangement, it is necessary to turn one of the two books after cutting the double-use according to the requirements described above.
  • the known turning devices which are arranged within the transport path of the cut double blanks to the three-knife cutting machine, have two work stations arranged side by side, each for a book.
  • One work station is formed by a turning station, while the other work station comprises a conveyor belt on which the book is conveyed without changing its position, since only one book needs to be turned at a time.
  • the turning station is formed by two cross straps, which grip the book on both sides and turn in the desired way. After leaving the complete turning device, the books lie in the desired manner on the conveyor belt leading further to the three-knife cutting machine.
  • the divided double-use can come from the printer in different forms, and depending on whether the two books are head-to-head or foot-to-foot in the case of the shared double-use, this must be seen in the top view of the conveyor belt seen overhead or underlying book can be turned while the other book is transported unchanged. If the books are printed foot to foot, the turning direction must also be changed in an opposite direction.
  • the invention has for its object to provide a turning device to avoid the disadvantages described, which allows easy adaptation of the turning device to the different divided double use without much loss of time and to turn either the upper or the lower book.
  • the basic idea of the invention is to provide a turning station on both sides of the conveyor belt, in deviation from the previously known turning devices. In this case, only one of the two turning stations needs to be actively in operation, depending on whether the upper or lower book of the divided double benefit has to be turned.
  • the main advantage of the new turning device lies in the fact that the changeover time is virtually irrelevant when changing the shape of the shared double-use, which has a positive effect on the economy of the system.
  • the turning device designated as a whole by the reference number 10 comprises a base frame 12 with a housing 14 in which there are electric motors for the drive. Underneath the housing 14 or the underframe 12 there are arranged wheels 16 with which the entire turning device 10 can be moved on rails 18 transversely to the conveying direction indicated by the arrow D.
  • the rails 18 are arranged on a foundation 20.
  • the turning device 10 further comprises a central conveyor belt 30, and on each side of the conveyor belt 30 there is a turning station 24 or 28, as can best be seen in the top view according to FIG. 2.
  • the turning station 24 located in the drawing in the top view at the bottom is formed by two cross belts 22 each, which are guided over deflection rollers 26 and be driven by an electric motor.
  • the other turning station 28 consists of two cross belts 32, which are guided over deflection rollers 34 and are also driven with the aid of an electric motor.
  • the distance between the deflecting rollers 26 and 34 arranged one above the other can be changed to adapt to different book thicknesses.
  • three controllers 40 are provided in order to be able to set the drive speeds for the conveyor belt 30 and for the two turning stations 24 and 28 or for their cross belts 22 and 32. Different speeds are required for a turning station on the one hand and the conveyor belt on the other hand in order to ensure that the book transported on the conveyor belt 30 without interference and the book turned by means of the cross belt lie directly above one another when leaving the turning device (or - depending on the desired further processing - also lie offset).
  • book 60 shown on the left in Fig. 3 takes the position shown in the right part of Fig. 3, i.e. the title page is now at the top, and the head 62 is also at the top, while the foot 66 is at the bottom.
  • the book 60 has thus been turned through 180 °, clockwise.
  • This turning process is carried out in FIG. 2 by the turning station 28, while the opposite turning station 24 effects a turning in the opposite direction - that is, counterclockwise.
  • the laterally movable turning device 10 can be brought and locked in accordance with FIG. 2 in three working positions A, B and C.
  • the turning device 10 in position A for the transport of the books 46 and 48 lying to the left of the turning device, which here lie head to head.
  • the lower book 48 is conveyed by the conveyor belt 30 without further influencing its position, while the upper book 46 is turned by means of the cross belt 32, so that the two books 46 and 48 in the desired manner after leaving the turning device 10 head to foot and in each case lie with the right side up.
  • the books coming from the printer are already correctly positioned as desired, as arranged by the two books 54 and 56, or that only a single book 58 has to be transported. Then turning is not necessary. The turning device then only needs to be used as a transport device.
  • the turning device 10 is moved into position B, which is indicated by the dash-dotted position line 42.
  • the two books 54 and 56 or possibly just one book 58 are then transported on by the conveyor belt 30 without further influencing the position.
  • the turning device 10 is moved into position C, which is indicated by the dotted position line 44 is clear. Now the lower book 52 must be turned over, for which purpose the lower turning station 24 with the cross belt 22 is used. Here, an opposite turn takes place, as is caused by the upper turning station 28. After leaving the turning device 10, the two books 50 and 52 assume the desired position shown on the right.
