Definitions

  • the invention relates to a device for welding and cutting of single or multilayer materials using ultrasound energy according to the preamble of claim 1.
  • US Pat. No. 3,852,144 discloses an apparatus for simultaneously welding and cutting weldable single- or multilayer materials using ultrasound energy and for this purpose has a sonotrode arranged above a working plate, which cooperates with a cutting wheel and a welding wheel arranged coaxially therewith. Both the cutting wheel and the welding wheel arranged at a slight lateral distance therefrom are arranged below the working plate and protrude into cooperation with the sonotrode through a slot provided in the working plate into the area of the sonotrode. The arrangement of the sonotrode and the cutting and the welding wheel is made such that the welding of the side edge of the weld material takes place simultaneously with the cutting process.
  • the welding wheel is driven by a geared motor via a gear train and at the same time forms the feed means for the weld metal, while the cutting wheel is stationary with respect to the cutting-welding operation and only when its edge has become dull, each such cyclically so far by an amount is rotated so that an even new area of the cutting wheel reaches the area of the sonotrode.
  • the cutting wheel and the welding wheel are independent of each other Sonotrode arranged and can be pressed with different forces against the sonotrode.
  • the cutting gap and the welding gap must each be set completely independently of each other.
  • Another disadvantage is that the welding wheel is not driven circumferentially with respect to the cutting process and therefore the respective effective region of the cutting wheel must be changed relatively often for reasons of wear. On the one hand, this requires a correspondingly frequent interruption of the actual work process and, on the other hand, an additional outlay for the device which effects the respective incremental further rotation of the cutting wheel.
  • the invention is therefore based on the object to provide a generic device which on the one hand facilitates both the adjustment of the cutting gap, as well as the welding gap and on the other hand creates the opportunity to drive the cutting wheel without significant additional design effort.
  • this object is achieved by the characterizing features of claim 1. Characterized in that the welding wheel and the cutting wheel are taken together by the support arm, a single downward movement of the support arm is sufficient to bring both the cutting wheel, as well as the welding wheel in a position from which then both the cutting wheel, and the welding wheel by means of the respective additional device in the required welding or cutting gap corresponding position can be brought.
  • the drive movement is transmitted via a belt drive on a shaft carrying the cutting shaft, eliminating the one hand wear-related frequent further rotation of the Sch ⁇ eidrades in a position in each of which a new area of its cutting in operative position comes and on the other hand results in so far a simple construction, as both a second support arm and in particular also a second drive for adjusting this additional support arm deleted.
  • a loss of its own drive for the welding wheel is achieved in that the drive movement of the cutting wheel is transmitted by a coupling to the welding wheel, with a further simplification is achieved in that the coupling formed by a cutting pin carried by the cutting pin and provided in the welding wheel recess is.
  • the means for changing the cutting gap on a spindle serving as a threaded pin which is attached to one ends on which the movement of the support arm causing carriage and the other end cooperates with a housing-fixed dial.
  • the welding wheel is mounted by means of an axis in a rocker, which in turn is supported by a parallel to the longitudinal axis of the rocker and mounted in the tag arm axis.
  • a simple and tool-free assembly and disassembly, as well as a backup of all arranged on the support arm mounted on the axis parts can be achieved if the axis has an annular groove for receiving a latching in this Pistonloches.
  • a structurally simple and inexpensive to produce means for changing the size of the welding gap, which exerts no influence on the size of the previously set cutting gap when it is set, is achieved if this comprises a nut fixed to the support arm with a axially movable spindle through this one end of which has a handle, and at the other end of which two staggered stops are provided, between which engages a fork-shaped end of a rocker integral with the rocker arm.
  • a part-saving solution for the printing device is achieved when on the rocker receiving axis additionally a lever of the printing device is pivotally mounted, the other end is formed as a housing for receiving an actuating means, and a spring-loaded pressure piece.

  • rocker 32 receiving axle 33 is also attached to the support arm 12, it only needs to adjust the welding gap of adjusting the height of the welding wheel 6.
  • the handle 42 By turning the handle 42 is acting as a spindle 38 threaded pin 39 axially displaced, whereby according to the direction of rotation of the handle 42, the left or the right nut 43 comes to rest on the corresponding side surface of the pivot arm 36.
  • the pivot lever 36 thereby performs a pivoting movement about the axis 33, whereby the rocker 32 fixedly connected to the pivot lever 46 is also pivoted about the axis 33. This leads to a change in the distance between the sonotrode 4 and the welding wheel 6, so that the welding gap is correspondingly increased or decreased.
  • the housing 47 of the printing device 45 is pivoted about the axis 33 upwards and occupies an obliquely downward position in which the pressure piece 51 a distance of several centimeters from the pressure surface 52nd has the rocker 32
  • the housing 47 is pivoted about the axis 33 by actuating the handle 50 formed thereon for adjusting the welding pressure.
  • the latching nose 55 attached to the lever 46 thereby pivots first the pawl 56 mounted on the trunnion screw 57 against the force of the compression spring 59.
  • the handle 50 If the resulting welding pressure is too great or too low, this can be increased or decreased by turning the handle 50.
  • the voltage of the disposed within the bore 48 compression spring 59 is increased or reduced accordingly. Since in this case the distance of the active surface of the pressure piece 51 from the pressure surface 52 of the rocker 32 does not change, the increase has or reduction of the welding pressure neither an influence on the size of the set welding gap, nor on the size of the set cutting gap.

Abstract

Dispositif de soudage et de coupe de matériaux monocouches ou multicouches à l'aide de l'énergie ultrasonore, qui comporte une roue de soudage (6) et une molette de coupe (5) placées sur un support commun et pouvant être déplacées ensemble par ce dernier. La roue de soudage (6) et la molette de coupe (5) sont associées chacune à un dispositif supplémentaire destiné à modifier la grandeur de la fente de soudage ou de la fente de coupe et ces deux dispositifs peuvent être actionnés indépendamment l'un de l'autre, si bien que le mouvement relatif de la roue de soudage (6) par rapport à la sonotrode (4) permet d'ajuster la grandeur de la fente de soudage et que le mouvement relatif de la molette de coupe (5) par rapport à la sonotrode (4) permet d'ajuster la grandeur de la fente de coupe.
