Definitions

  • the present invention relates to a sampling method for flat products carried by a conveyor and an apparatus therefor. More particularly, the present invention concerns a method of and apparatus for sampling one or a plurality of pieces of signatures continuously carried from a printing machine or the like by a conveyor.
  • An object of the present invention is to provide a method of and apparatus for automatically sampling one or a plurality of pieces of the flat products placed on a carrying conveyor and continuously carried.
  • part of the flat products which are carried while being overlapped on a conveyor, shifted in the carrying direction, and exposed at their edges on the downstream side of the carrying direction, are sampled from the conveyor as follows.
  • one of the edges of the flat products carried by the conveyor is detected by means of an edge detecting means provided at a specified position.
  • a knife waiting at a stand-by position on the downstream side from the edge detecting means and upwardly from the conveyor is descended on the basis of an edge detection signal from the edge detecting means.
  • the knife is then inserted between the flat products from the above-described detected edge.
  • the flat products which are held on the upper surface side of the inserted knife are clamped on the knife.
  • the flat products clamped on the knife are sampled by the movement of the knife.
  • the knife when the knife is descended, preferably, it softly touches the upper surface of the flat product or the carrying surface of the conveyor. This prevents the flat products from being damaged.

  • the conveyor 60 is preferably disposed such that the upper surface of the conveyor has a slight rising gradient when being connected to the carrying conveyor 1.
  • the rising gradient on the upper surface of the conveyor is dependent on the strength of the waist of the signature 4 (mainly strength of holding the shape of the signature itself due to the thickness).
  • the thickness of the signature 4 is thin and thereby the strength of the waist is weak and the folding is made small, it is not required to provide the rising gradient on the upper surface of the conveyor.
  • the signatures 4 are carried on the carrying conveyor 1 while being overlapped to each other in a manner of tiles of a roof.
  • the signature 4 is lifted up at the height of the roller 2 so that the height of the edge 5 of the signature 4 is certainly distinguished from the preceding signatures 4.
  • An interval can be confirmed between the continuous signatures 4 by the detecting sensor 3.
  • the motor 7 as the drive unit is started for turning the arm assembly 8 standing-by at an action starting position 8a.
  • the arm assembly 8 is rocked between positions shown by 8a, 8b ... 8h around the arm shaft 6 as shown in Fig. 1. Furthermore, at the positions 8a, 8b, 8c, and 8d, the arm assembly 8 is moved along the guide groove 23 of the guides 22 and 22, so that the shaft 20 located at the lower end of the first arm unit is moved in parallel to the carrying conveyor 1.
  • the rollers 24 and 24 of the first arm unit advance in the guide groove 23, and thereby the first arms 14 are extended/contracted and the second blocks 21 and 30 are linearly moved in parallel to the carrying conveyor 1 along the guides 22. Subsequently, by operation of the cylinder 34, the second arms 33 are descended, and the lower surface of the knife 9 abuts on the upper surface of the signature 4 carried on the conveyor 1.
  • the rear end of the knife 9 is biased upwardly by the spring 48 and abuts on the stopper 50.
  • the leading edge of the knife 9 is turned upwardly against the spring 48, so that the abutment between the rear end of the knife 9 and the stopper 50 is released.
  • the lower surface of the knife 9 softly abuts on the upper surface of the signature 4, which prevents the signature 4 from being damaged.
  • the leading edge of the knife 9 is descended somewhat downwardly from the upper surface of the conveyor 1, and the knife 9 certainly abuts on the upper surface of the signature 4 (position 8b).
  • the rotational frequency of the motor 7 is controlled such that the moving velocity of the knife 9 is smaller than the carrying velocity of the conveyor 1, or the movement of the knife 9 is stopped for a specified period of time.
  • the leading edge of the knife 9 is inserted between the signatures 4.
  • the clamping member 10 is turned upwardly such that the signatures 4 are placed on the upper surface of the knife 9.
  • the knife vertically moving cylinder 34 is reversely operated to ascend the second arms 33, thus ascending the knife 9.
  • the stopper cylinder 37 is previously operated, to set the ascending position of the second arms 33 (position 8c).
  • the ascending position is set at a position where the lower surface of the leading edge of the knife 9 is slightly separated from the upper surface of the signature 4.
  • the knife 9 By separating the leading edge of the knife 9 from the signature 4, the knife 9 is turned by the spring 48 and abuts on the stopper 50, to be thus stabilized in its posture.
  • the sampling motor 7 is accelerated (two to four times the speed of the carrying conveyor 1), to rotate the arm assembly 8 (positions 8d-8f), thus sampling the signatures 4 from the conveyor 4.
  • One or a plurality of the signatures 4 may be held on the knife.
  • the parallel movement of the knife 9 is stopped for a specified time at the position 8b, and the signatures in a specified number are joggled and then held.
  • the signatures 4 may be clamped; however, in this state, the spring 48 biases the other end of the knife 9 and thereby the stopper 50 does not abut on the knife 9 so that the operation of the cylinder 44 makes instable the posture of the knife 9, which causes the fear that the signatures 4 contacted with the lower surface of the knife 9 are damaged. Accordingly, to cope with this problem, it is desirable to ascend the knife 9 up to the rising position set by the knife stopper cylinder 37, and to clamp the signatures 4 at the position where the other end of the knife 9 stably abuts on the stopper 50.
  • the arm assembly 8 is turned, and at the time when the arm assembly 8 reaches the position 8g, the sampling motor 7 is stopped, and then the clamping means 53 is opened to release the signatures 4, so that the signatures 4 are discharged on the stacker 52 with a good posture.
  • the knife vertically moving cylinder 34 and the knife stopper cylinder 37 are reversely operated, and thus the sampling motor 7 is returned at the original point and the clamping means 53 stands by the action starting position.
  • the foregoing action is performed for sampling the signatures 4 to the upper stacker device 52.
  • an action of sampling a plurality of signatures 4 downwardly from the junction between the carrying conveyor 1 and the second conveyor 60 will be described.
  • the action is referred to "discarding-sampling".
  • the knife 9 is inserted between the signatures 4 and is stopped for a specified time at the position 8b wherein they are ascended by the specified height to joggle the signatures 4 (the movement of the signatures on the driving conveyor is temporarily stopped).
  • the joggling operation is as follows: namely, after the second conveyor 60 permits the passing of the preceding signatures 4, and is rocked to fully open the interval with the preceding signatures 4 with the matched timing to release the connection with the carrying conveyor 1.
  • the signatures 4 are placed on the preceding signatures 4, and the second conveyor 60 is rocked thereon, to be connected with the carrying conveyor 1, so that the signatures following the pulled signatures 4 are desirably carried and are returned to a main stream.
  • the embodiment described in this specification is illustrative and is not restrictive.
  • the knife vertically moving cylinder 34, the knife stopper cylinder 37, and the clamp cylinder 44 are not limited to a direct moving (linearly moving) cylinder type; but it can apparently achieve its function fully by replacement of the type with a rotary drive means such as a rotary cylinder or pulse motor.
  • the arrangement of the flat products 4 on the conveyor 1 is not limited to the manner of tiles of a roof; but may be of a form in which intervals are generated between the preceding flat products and the following flat products (see Fig. 9).
