  • gripping devices are provided for the strips of a packaging material in which the products are wrapped in order to form packaging for sale.
  • the gripping devices cooperate with the feeding device arranged in a first fixed structure of the machine and are assembled with the conveying members or are located in a second fixed structure of the machine.
  • US-A-2 723 516 relates to a packaging machine in which a feeding device is provided which is attached to a fixed structure of the machine and is suitable for depositing a strip of packaging material on a conveyor element before a soap is in this conveyor element.
  • a feeding device solves the task of placing the strip on the flat surface of the conveying member only when the packing machine is moving slowly, namely the strip can only be correctly moved from the feeding device onto the flat surface of the conveying member if the conveying member has a sufficient amount in the feeding device For a period of time to move the strip on which a surface of the soap rests from the feed device to the conveyor member.
  • European patent application No. 90103891.9 filed on February 28, 90 by the applicant, relates to a high-speed packaging machine in which a plurality of conveying members are provided for soaps. With the funding links pliers for gripping strips of packaging material are assembled. Each strip comes individually from a feed device that is like that of USA-A-2 723 516.
  • Each of the conveying members described in the European patent application is equipped with a gripper that is kinematically connected to gears for monitoring their operation in the various working phases of the machine.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of creating a conveying member with levers for packaging machines of products susceptible to damage with a gripping device for strips of packaging material for wrapping the products and a machine with the same conveying member.
  • Using the invention achieves the result of moving the strip of packaging material from the feeding device to the conveyor member when the same conveyor member is close to the feeding device; to this end a gripping device is used which consists of one of the actuation levers and of an end stop member for limiting the movements of the same actuation lever, the end stop member being fastened to the conveying member.
  • the same conveying member comprises: a supporting structure supported by a radial slideway, the slideway belonging to a carousel of the packaging machine which rotates around a bearing carried out in a supporting plate; first and second actuation levers, each of the actuation levers rotating about its own pin provided in the supporting structure; the actuating levers are suitable for carrying a product while the supporting structure moves from a first loading point of the products into the machine to a second unloading point of the products from the machine; an end stop member for limiting the rotational movement of a first actuation lever in the direction of distance of the first actuation lever from the second actuation lever, the end stop member being fastened to the supporting structure and being suitable to be used with the first actuation lever to form the gripping device of the Strip to cooperate; Control means for controlling the movements of the operating levers during the rotation of the carousel; in addition, the packaging machine has guide members for guiding the
  • the end stop member preferably consists of a bracket which protrudes from one side of the supporting structure.
  • the bracket advantageously has a bend in order to arrange its free end in the region of the movements of the free end of the first actuation lever.
  • the bracket is formed by a rod made of an elastic material, the rod bending under the action of the free end of the actuating lever.
  • the bracket is located in the front part of the supporting structure in the direction of rotation of the conveyor member.
  • the movements of one of the actuation levers are controlled by a control lever, the first end of which is attached to the same actuation lever in rotation and the second end of which supports a bearing which runs in a grooved annular contour, the contour being in the load-bearing one Plate stretches;
  • the movements of the other operating lever are controlled by a gear mechanism consisting of a first gear wheel rotatably mounted on the operating lever controlled by the control lever and one on the other operating lever rotatably attached second gear.
  • the guide members for the ends of the strip consist of an inner surface of a guide structure, the inner surface being suitable for bringing the strip into contact with the flat surface provided in the conveying member.
  • the guide structure extends between a first point arranged near the feeding device for the strip and a second position of the conveying member, in which the strip is located between the flat surface and a surface of the product.
  • FIG. 1 shows six conveying members 4 which are located in six places in the carousel 6 and in different states of the actuating levers with regard to the products 2, such as that in FIG European patent application was written.
  • the conveying member 4 receives a strip 8 of packaging material from a feed device 7, which essentially consists of two feed rollers 9.
  • the gripping device of the conveying member 4 engages one end 10 of the strip 8, the second end 11 of which in the course of the movement of the conveying member 4 from the point B to a third point C in contact with an inner surface 12 of a guide structure 13 for the ends 11 is obtained in order to bring the strip 8 into contact with a flat surface 14 provided in the conveying member 4.
  • the guide structure 13 extends between a point located near the feeding device 7 and point C.
  • the strip 8 is located between the flat surface 14 and a surface of the product 2, the opposite surface of which is supported on the flat surface of the support member 5.
  • a sixth position F the conveying member 4 places the product 2 in an unloading conveyor belt (not shown); therefore its actuation levers are removed from product 2.
  • the flat surface 14 is located at the end of a supporting structure 15, which is assembled with the carousel 6, as described in the above-mentioned patent application.
  • a first actuating lever 16 for conveying products 2 rotates about a first pin 17 provided in the supporting structure 15, the axis of rotation of which is perpendicular to the position of the movement of the conveying members 4.
  • the operation of the lever 16 has been amply described in the above patent application. We explain expediently that the lever 16 is fastened in rotation to a first end 18 of a control lever 19 shown in FIG extends in a supporting plate 23; the supporting plate 23 is equipped with a bearing for supporting the carousel 6.
