Definitions

  • the invention applies more particularly to the laying of an adhesive tape on filiform products, in particular strands or bundles of wires, without thereby excluding other products which must be held together.
  • Apparatuses of the strapping type are also known.
  • the product is introduced on one side to be subjected to the action of the adhesive tape, but cannot be removed from the same side.
  • This laying technique turns out to be incompatible in the case of bundles or strands of great length where it is necessary to lay a large number of links at different places along the length of the product.
  • the rotary head has an opening whose profile is determined according to the type of product concerned.
  • the invention has set itself the aim of remedying in a simple and effective manner, the drawbacks caused by the various devices as defined above.
  • the problem which the invention proposes to solve is to be able to attach together, in an automatic manner, from products, in particular filiform products, such as strands or bundles of wires, under the following conditions and objectives, considered in combination : - using a link in the form of an adhesive tape, - by enclosing the entire section of the product (s) over at least one turn and generally over several turns, regardless of the diameter of the product (s) concerned, - by removing all protruding parts, after applying the adhesive tape, - by inserting and removing the device on the same side of the product (s).
  • the device comprises means for gripping a part of the ribbon in order to position it opposite a winding member capable of cooperating with the product to enclose it over at least one turn with the part of the strip seized without leaving protruding tabs, the approximation or relative distance of the winding member and the product being effected on the same side.
  • the problem posed is solved in that the winding member is constituted by a rotary head having a radial opening capable of simultaneously driving the part of the tape gripped around the product which cooperates with means of immobilization in rotation.
  • the gripping means consist of an articulated clamp arranged with members capable of grasping and unwinding a length of ribbon to position it opposite the opening of the winding head in combination with the movement of said clamp.
  • the clamp has on either side of the winding member, two articulated flanges coupled to a control member of the jack type; at the end of these two flanges and between them is mounted a transverse roller capable of ensuring the installation of the free end of the tape in combination with profiled fingers mounted between said flanges and subject to a control member.
  • the drive of the winding head is carried out by a system of pinions subjected to a geared motor.
  • the periphery of the head meshes with two pinions arranged symmetrically to the axis of rotation of said head and at an angle greater than the angle of the radial opening of the head, said pinions meshing with a motor pinion.
  • the opening of the rotary head has a profile complementary to that of the product to be enclosed, said opening having a lining capable of allowing the ribbon to be driven.
  • the device has at the winding member, a means capable of cutting the length of the tape seized.
  • the adhesive tape cooperates with a shaped support member to avoid the possible backward retraction of said tape under the effect of its elasticity.
  • the means for immobilizing the product consist of articulated fingers mounted in combination with the flanges of the clamp, and whose free ends are profiled to ensure the immobilization of the product under a pivoting effect of said fingers subject to a control member.
  • all of the means constituting the apparatus and capable of solving the problem posed are controlled by an automatic mechanism to ensure the following operating cycle: - Angular pivoting of the clamp and closing of the gripping means to grip the free end of the adhesive tape. - lowering of the clamp to pull a length of ribbon and position it opposite the opening of the winding member. - Opening of the gripper gripping means. contacting the product and the part of the adhesive tape gripped for positioning said tape and said product in the opening of the winding member. - closure of the product immobilization fingers. - rotation control of the winding member and of the cutting means.
  • the body of the device designated as a whole by (1), comprises a rotary support (2) in the form of a reel, for example shaped to receive the adhesive tape (R) packaged in a roll.
  • the ribbon (R) is routed in combination with different return members (3) at the active part of the device shaped with means capable of ensuring the winding of said ribbon (R) on the product concerned (P).
  • this active part comprises means for gripping a part of tape to position it opposite a winding member (4).
  • this winding member (4) is shaped in combination with other means to grip, over at least one revolution, the entire section of the product (P) without leaving any protruding parts.
  • the ribbon gripping means (R) consist of an articulated clamp (5) secured to a control means (V) in the form of a jack in particular.
  • the clamp (5) comprises two parallel flanges (5a-5b) mounted with free articulation on either side of the winding member (4).
  • the two flanges (5a and 5b) are braced on the side of the winding member (4) by a transverse roller (6) intended to ensure the taking of the free end of the adhesive tape (4) in combination with profiled gripping fingers (7).
  • the fingers (7) two in number in particular, are arranged between the flanges (5a) and (5b) of the clamp while being coupled to a control member (8) such as a jack to ensure their movement with the against the transverse roller (6).
  • the fingers (7) capable of gripping the ribbon, are conditioned to ensure safe and effective maintenance of the latter during its course and facilitate its relaxation during the introduction of the product into the clamp or vice versa.
  • the fingers (7) are made of a relatively soft plastic material, while their free end has a semi-circular profile (7a) complementary to that of the section of the roller (6) to ensure in combination the pinching of the grip end of the ribbon.
  • the roller (6) is striated according to its generatrices and is made of steel.
  • the winding member (4) is constituted by a rotary head having a radial opening (4a) capable of entraining, in a concomitant manner, the part of the ribbon (R) gripped at the as and when the rotation of said head in combination with immobilization means (9) of said product.
  • the head (4) is rotated by a pinion system secured to a geared motor (10).
  • the periphery of the head (4) meshes with two pinions (11) and (12) arranged symmetrically with respect to the axis of rotation of the head (4).
  • These two pinions (11 and 12) are offset behind the axis of rotation of the head (4) and mesh with a motor pinion (13).
  • the pinions (11 and 12) are angularly offset according to a angle (A) greater than the angle (B) formed by the radial opening (4a) of the head (4).
  • the opening angle (B) of the head (4) is approximately 90 °, while the positioning angle of the pinions (11 and 12) is of the order of 120 °.
  • the opening (4a) of the head (4) has a profile complementary to that of the product (P) to be clamped. This opening also receives, directly or in a separate manner, a lining capable of facilitating the entrainment of the ribbon.
  • the head (4) has a central core (4b) cut in a manner corresponding to the opening (4a); this core being made of an elastically deformable material.
  • This core is engaged in the opening of an open cylinder (4c) the periphery of which receives in whole or in part a leaf of spring steel (4d) or other equivalent element whose free ends are folded back inside the openings of the support cylinder (4c) and of the central core (4b).
  • the entire head (4) thus defined can be housed inside another open cylinder (4e) whose periphery has a toothing (4f) meshing with the toothing of the drive pinions (11) and ( 12).
