Definitions

  • the present invention relates to a device for preparing wire sections from a wire for a stapler for stapling multi-sheet printed products such as newspapers, magazines and the like, according to the preamble of claim 1.
  • a device of this type is known from US Pat. No. 3,762,622.
  • This has a wire section dispensing unit with a feed part for gradually feeding a wire to a cutting device.
  • a lever-shaped cutting tool is provided, which is driven to rotate about an axis running parallel to the feed direction of the wire and has driving teeth at its radial end area, which strike the advanced starting area of the wire and, in cooperation with a fixed knife, separate a wire section from the wire .
  • the wire section is held between the cutting tool, the driving teeth and a circular guide element and moved about 90 ° with the cutting tool and fed to a receiving part.
  • the receiving part has a receiving gap delimited by a stationary block and a leaf spring tangential to the path of movement of the driving teeth and with its longitudinal extension perpendicular to the wire section, into which the wire section is inserted while sliding away from the driving teeth.
  • the wire section is in the receiving gap due to the leaf springs held.
  • a rotating stapling head has a driving part protruding outwards in the radial direction with a driving flank which, when the stapling head moves past the receiving gap, strikes the wire section and takes it over and conveys it away.
  • the wire section held by the entraining part is then bent into an open clamp and pushed and bent through several paper webs lying one above the other by means of the stitching head.
  • the initial area of the wire is inserted into a groove-shaped recess in a receiving part with play.
  • the device is therefore not critical to wire dimensions. It also enables even slightly bent wires to be processed.
  • the dimensions of the opening of the recess are so large that the wire section separated from the wire can emerge without problems. But since this opening by the end of the If the cutting process is closed by a take-over part that can be moved past the receiving part, the wire section cannot fall freely out of the recess, but is caught in it until it is gripped by the take-over part and conveyed away. The wire section is thus taken over by the takeover part approximately where it is separated from the wire.
  • the recess is shaped such that when the beginning of the wire is introduced obliquely towards the bottom of the recess, the wire section to be cut off from the wire is aligned approximately parallel to the take-over part, which enables the wire section to be taken over without problems.
  • the wire section reaches a groove-shaped recess in the driving part, where it is held by means of a magnet.
  • the removal of the wire section away from the receiving part is ensured in a particularly simple manner.
  • an adjustable wire guide element By means of an adjustable wire guide element according to claim 4, it is ensured in a particularly simple manner that the wire start area inserted into the recess from the feed part cannot protrude through the opening.
  • Claim 5 defines a particularly preferred and extremely simple embodiment of the wire guide element.
  • the device for processing wire sections 10 shown in the figures has a wire section dispensing unit 14 driven by a drive unit 12 and a wheel-shaped take-over device 16 also driven by the drive unit 12.
  • the take-over device 16 takes over from the wire section dispensing unit 14, the wire sections 10 prepared therefrom from a wire 18 and feeds them to a schematically indicated stapler 20.
  • a stapler 20 with a plurality of stapling heads arranged one behind the other and rotating in the direction of arrow A is described in detail in Swiss Patent Application 01 964 / 89-3.
  • particularly suitable stitching heads for taking over wire sections 10 are disclosed in CH patent application 01 963 / 89-1.

  • the length of the receiving part 40 and thus of the recess 42 corresponds approximately to the greatest length of the wire sections 10 to be processed.
  • the recess 42 which is approximately U-shaped in cross section, is designed in its dimensions such that it has the largest diameter (approximately 1 mm.) Of the wire 18 to be processed ) still includes game.
  • the opening of the recess 42 is designated 44 and this is also so large in its dimensions that the wire section 10 cut from the wire 18 can fall freely downward from the recess 42.
  • the opening 44 is arranged slightly below the outlet 36, so that the initial region of the wire 18 pushed into the recess 42 comes to lie within the latter.
  • the recess 42 is formed deeper at the end facing the outlet 36 than at the end remote from the outlet 36, which ensures that even wire 18 inserted obliquely upwards into the recess 42 is aligned such that it is approximately parallel to the opening 44 and thus in Longitudinal direction of the wire guide element 34 extends.
  • the wire guide element 34 is shown enlarged in FIGS. 4 and 5.
  • This has an approximately hollow cylindrical tube part 46 which is inserted into a bore 48 in the feed direction B of a holding plate 48 'projecting from the bearing block 32 and is clamped in this by means of a screw 50.
  • a guide sleeve 52 is inserted into the tube part 46, the input 52 'of which is conically tapered in order to guide the beginning of the wire 18 into the guide bore 52' 'adjoining the input 52' when the wire 18 is inserted.

  • the shaft 58 which is formed at one end with a head 60, can be rotated about the axis 58 'and can be fixed in the desired rotational position by means of a nut 60' opposite the head 60 with respect to the tube part 46 and screwed onto the shaft 58.
  • the shaft part 58 ′′ forms a guide member which can be brought into contact from above by twisting the shaft 58 against the wire 18 indicated by dashed lines in FIG. If the shaft part 58 ′′ is in its uppermost position, the wire 18 can run essentially in a straight line from the guide bore 52 ′′ to the passage part 56 ′. However, if the shaft part 58 ′′ is brought into position by dash-dotted lines in FIG.
  • the shaft part 58 ′′ exerts a force on the wire 18 which has a slight intrinsic curvature, which causes the wire to rotate about its longitudinal extent, so that the intrinsic curvature is directed upwards.
  • the takeover device 16 (FIGS. 1, 2, 6) has an in Arrow direction D revolving driven takeover wheel 62, along the circumference 12 takeover parts 64 are arranged resiliently biased in the radial direction towards the outside.

  • a link 66 cooperating with the take-over parts 64 is fastened, in which the receiving part 40 is embedded in the central region, and its distance from the axis of rotation 62 'of the take-over wheel 62, seen in the direction of rotation D, forming an inlet on the start side, up to the receiving part 40 decreases and follows the receiving part 40, forming an outlet again increases.
  • each take-over part 64 which cooperates with the link 66, is designed in the form of a sliding shoe and has, in the central region, a recess 68 which runs parallel to the axis of rotation 62', the trailing boundary of which in the direction of the arrow D forms a driving flank 68 'for the respective wire section 10 and in the bottom area of which a magnet 70 is provided for holding the wire section 10.
  • a take-over part 64 runs onto the link 66, it is pressed against the inside in the radial direction, so that the sliding-shoe-shaped end region 64 ′ bears against the link 66.
  • the movement of the take-over parts 64 in the direction of rotation D and the knife 38 are synchronized with one another in such a way that the take-over part 64 running past the recess 42 closes the opening 44 at the latest until the end of the cutting of a wire section 10 from the wire 18, so that the wire section 10 does not stop the recess 42 can fall out.
  • the position of a take-over part 64 which just closes the opening 44 is indicated by dashed lines in FIG. 6.
  • the wire section 10 then falls under the force of its own weight and is attracted downward by the magnet 70 into the passing recess 68 and is held there by the magnet 70 and carried along by the driving flank 68 ', as is indicated by dash-dotted lines.
  • the cutting off of a wire section 10 may therefore at the earliest when the opening 44 is closed by a takeover part 64 and must be completed at the latest when the recess 68 runs past the opening 44, which certainly allows tolerances in the synchronization between the cutting device 24 and the takeover device 16.
