  • SHEET '4 OF 4 MACHINE FOR BINDING AND 'IYING UP PACKAGES R BUNDLES The present invention is concerned with a machine for binding and tying up packages or bundles.
  • the retaining means are so devised that after the completion of each knot the strand between the package or bundle and the string guiding arm as well as the strand of string from the package to the end of the string are both gripped by the retaining means and cut. A length of string is therefore cut off this latter strand and drops into the machine as waste. These surplus pieces of string often cause trouble.
  • Another important object of the invention is to simplify the mechanism by eliminating the need for a special cutter, the carrier arm for such a cutter and the cam for operating the arm.
  • a further object of the invention is to effect a saving in the consumption of string when tying up packages and bundles of given diameter.
  • the retaining means includes a support having rounded string guiding faces and is movable from a position of rest against the resistance of a spring towards the knotter, and two cam-operated retaining arms eachformed with a hook-shaped recess for forming two string gripping points, namely a rear gripping point and a front gripping point closer to the knotter, with operation of said retaining arms by the cams being so controlled that at the beginning of a working cycle the end of the string held at the rear is first also wedged in the front gripping point and then released at the rear gripping point, that during the knotting operation the entire retaining means are pulled towards the knotted against theresistance of the spring, and that the cutter means consist of a knife edge which on that retaining arm which together with'the support forms the front gripping point is formed in front of the hook-shaped recess, said knife edge taking effect after the knotting operation, during the first part of the movement of said retaining arm in the direction of releasing the end of the string from the
  • FIG. 1 is a perspective view of the machine showing the movable parts in the positions they occupy when the machine is stopped,
  • FIG. la is a view of the string retaining mechanism seen from above
  • FIGS. 2a, 3a, 4a, 5a and 6a are views from above corresponding to FIG. In of the retaining mechanism in positions corresponding to those shown in FIGS. 2, 3 and 6, respectively.
  • the machine for binding packages or bundles according to the invention comprises a frame, not included in the drawing, which carries a table T provided with an opening 1 for a string withdrawing and guide arm 2.
  • this arm can swing about a fixed pivot in part of the machine frame.
  • the string which is withdrawn from a reel via tensioning means runs over deflecting rollers mounted on the arm and then through a hole 3 in the free end of the arm.
  • a mainshaft 4 is rotatablymounted under the table T in the machine frame. This shaft performs one revolution for forming a loop around a package-or bundle and for simultaneously tying a knot.
  • the shaft is driven-by an electric motor, likewise not shown, and a transmission shaft 5.
  • knotter K of conventional construction.
  • the knotter is rotatable about a shaft 6 in a swing mount, not shown, mounted on the control shaft 4.
  • the swing mount and the knotter swing out of the plane of the drawing towards the viewer when the tying of the knot is about to be completed.
  • the knotter performs a complete revolution in the direction indicated by an arrow 7. This movement is imparted thereto by a coned pinion 6a which is fast on the shaft 6 engaging a gear segment on a circular plate 8 affixed to the mainshaft 4.
  • the knotter has a knotter bill .2 which can be hingeably raised and lowered and which forms part of a cranked lever mounted on the knotter.
  • the knotter bill is raised only during the last part of a knotter revolution, i.e. during the completion of the knot, a small roller R on the other arm of the lever during this phase bearing against a stop which is provided on the above mentioned swing mount, and which is deflectable against the resistance of a spring by the traversing roller R.
  • the roller R rides on a surface of the swing mount which is coaxial with the shaft 6.
  • a certain distance away from the knotter K on the left is a retaining mechanism generally indicated by H.
  • This retaining mechanism comprises a support 9 and a retaining plate 10 bearing against that side of the support which faces the knotter, support and plate both preferably consisting of nylon.
  • the support 9, the retaining plate 10 and two leaf springs l1, 12, of which one bears against the other side of the support and the other against the outside of the retaining plate I0, are attached by screws 13 to the upper end 14a of a carrier arm 14.
  • the carrier arm has a framelike lower end portion 14b which is deflectable on pivot pins 16 in fixed bearing members 15 towards the knotter K.
  • a powerful spring 17 seeks to keep the arm in position of rest in contact with a fixed abutment I8.
  • a pivot pin 19 The ends of a pivot pin 19 are fitted into the sides of part 14b said pin being parallel to the mainshaft 4 when the carrier arm 14 is in position of rest.
  • Deflectably mounted on this pin are two retaining arms 20, 21 of which each carries a follower roller 22 and 23 respectively maintained in contact with a cam 26 respectively 27 by a spring 24 respectively 25.
  • the cams are fixed on the mainshaft 4 and thus control the deflections in relation to the support 9 of the retaining arms 20, 21 about the pivot pin 19.
  • the upper arched shanks 20a and 21a of the retaining arms move in a slot 28 respectively in a recess 29 laterally adjacent the retaining plate 10 at the upper end of the support 9. This end of the support thus forms fins 9a, 9b with rounded ends adjacent the slot and the recess, as indicated at 9c.
  • Each of the shanks 20a, 21b of the retaining arms contains a hook-shaped recess 30 respectively 31 for the reception of parts of the string which, as will be later described, are wedged during the rearward deflection of the relative retaining arm.
  • a rear gripping point C1 is formed by the cooperation of the edge of the hooked recess 30 in the retaining arm 20 with the adjacent rounds 9C, and as will be understood from FIGS. 4, 4a, 5 and 5a
  • a front" gripping point C2 closer to the knotter K is formed by the cooperation of the edge of the hook-shaped recess 31 in retaining arm 21 with the side of the fin 9b facing the recess 29.
  • the gripping point C2 extends to a rounded edge 10b on the front of an upward projection 10a at the back of the clamping plate '10.
  • the part of the string which is gripped at this point is the end of the string. It comes to lie between the fin 9b of the support and the shank 21a of the retaining arm 21, the latter together with the clamping plate 10 and the leaf spring 12 laterally yielding.
  • a headed screw 33 which passes through this leaf spring 12, the clamping plate 10, the support 9 and the leaf spring 11 carries a nut 34 and a lock nut 35 which limit the lateral deflection of the parts 21a, 10 and 12.
  • an extension 21b of the shank 21a projects beyond the knife edge 31.
  • the cam 27 has further deflected the retaining arm 21 forward out of the plane of the drawing towards the viewer carrying the end S of the string towards the projection 10a without releasing the same from the gripping point C2 whilst the end is additionally gripped by the projection (FIG. 4).
  • the knotter K begins to rotate about its shaft 6 in the direction of the arrow 7. consequently it forms a loop each in strand S of the string and in the strand S of the string which adjoins the end S, that is wedged in the front gripping point C2, these loops embracing the upper part of the knotter and the knotter bill 2, as shown in FIG. 5.
  • a certain length of string is required for forming these loops and since the strand S1 of the string is firmly held by the front gripping point C2, the latter must yield by moving towards the knotter K.
  • the assembly 9, 14, 20, 21 is pivotably deflectable about the pivot pin 16.
  • the spring 17 can yield to this deflection.
  • the formation of the knot is completed in conventional manner by the return of the swivel mount carrying the knotter, permitting the two loops which embrace the upper part of the knotter and the knotter bill to slide off over the strands of the string which had been retained between the top of the knotter and the knotter bill, and which are'now withdrawn from the knotter by the return deflection of the swivel mount.
  • the tied and bound package can now be removed from the table T.
  • the position shown in FIG. I is thus reestablished and the next working cycle can be begun by pushing another package that is to be tied onto the table.
  • a machine for binding and tying up packages or bundles comprising a table provided with an opening, a driven string guiding arm capable of performing one reciprocation during each tying operation, through said table opening, a knotter mounted below said table and a retaining means for the string which cooperates with said string guiding arm to form the knot, and includes cutting means for cutting the strand of string between the finished knot and the string supply at a point near the freshly formed knot, said retaining means including a support having rounded string guiding faces and being movable from a position of rest towards said knotter, a spring tending to retain said support in its rest position and two retaining arms each formed with a hook-shaped recess for forming two string gripping points, namely a rear gripping point and a front gripping point closer to said knotter, driven cams capable of operating said retaining arms so that at the beginning of a working cycle the end of the string held at the rear gripping point is first also wedged in the front gripping point and then released at the rear gripping point,
