Definitions

  • the invention relates to a (manually operated) device for attaching an element to a carrier material, having a first tool and a second tool, at least one of which can be moved against the other by means of a drive in order to deform the element in between in such a way that that it is attached to the carrier material.
  • Attachment devices of the type described above are known. They are used in particular for attaching closing elements, such as push-button elements, to textile, leather and plastic articles.
  • the known attachment devices work with a pneumatic drive.
  • a coupling is provided which serves to couple the movable tool to the drive or to it from it decouple. Since the attachments are mostly operated manually, they must be stopped after each working stroke. For this purpose, a stop is provided in known attachment devices, against which the movable tool runs after completion of the working stroke, which is associated with considerable noise.
  • the working pressure i.e. H. the pressure with which the element to be fastened is deformed is adjustable.
  • the carrier material can have different elasticities, for example because of different material thicknesses or because of different numbers of material layers, the working pressure must be readjusted in each case.
  • the invention has for its object to provide a piecing device of the type mentioned, which operates with little noise or in which the deformation pressure exerted on the element is independent of the carrier material or its resulting elasticity.
  • this object is achieved in that the drive has a motor and a cam mechanism.
  • the drive that is no longer driven after the fastening process ie. H. outgoing motor are stopped in the area assigned to the dead center of the movable tool.
  • the braking force of the internal friction of the engine and the transmission is also used.
  • attachment device in the case of a piecing device operated manually as well as in a different, for example automatically, attachment device it is provided that one of the tools is biased towards the other tool in such a way that it dodges when a limit pressure is exceeded.
  • a cam disk of the cam mechanism is mounted eccentrically. As a result, the lateral forces acting on the moving tool can be minimized.
  • the driven surface of a cam disk of the cam mechanism has a smaller curvature in an area assigned to a dead center of the movable tool than in other areas. This results in a strong braking or holding effect.
  • the area of lesser curvature associated with the print dead center preferably extends over an angle of 10 ° up to 25 °.
  • the area of lesser curvature associated with the dead center preferably extends over an angle of 90 ° to 150 °. This measure in turn serves to hold or brake the engine at the dead center.
  • a spring which is preferably provided according to the invention for biasing the movable tool against the driven surface of a cam disk of the cam mechanism. It should be expressly pointed out that, according to the invention, such a spring can be used not only in cam gears, but also, for example, in gears with a thrust crank if braking and / or holding in the area of the dead center is desired.
  • the force with which one of the tools is biased in the direction of the other tool in order to establish the limit pressure explained above can be preset, which can be useful if the attachment device is only for one type of element and only for one type of carrier material is designed. However, if the attachment device should be universally applicable, i. H. For different elements on different carrier materials, it is preferred according to the invention to make the aforementioned pretensioning force and thus the resulting limit pressure adjustable.
  • the drive can include an electric motor.
  • This configuration is particularly useful when the attachment machine is intended for home work.
  • a power supply connection is available in almost every household, whereas only a few have a pneumatic network.
  • An electric motor can be used, in particular if the above-mentioned preload is provided for establishing the limit pressure, in particular with a view to the fact that the working pressure in the electric motor cannot be preset as precisely as in a pneumatic system.
  • the limit pressure can, however, be specified precisely.
  • FIGS. 1 and 2 shows schematic front views of two preferred exemplary embodiments of the invention, which differ only in the outer shape of a cam disk.
  • An electric motor not shown in the drawing, drives a cam disk 10, which is mounted eccentrically at 12.
  • An upper tool 16 bears against the cam disk 10 via a support roller 14.
  • the upper tool 16 is slidably mounted at 18.
  • a lower tool 20 which is biased upwards by means of a spring 22.
  • the spring 22 is adjustable in its tension to adjust the limit pressure.
  • the lower tool 20 is slidably supported at 24.
  • a hold-down 26 keeps the lower tool 20 below a predetermined level.
  • a support table 28 is provided on the lower tool 20, on which the carrier material 30 is arranged.
  • the element 32 to be fastened to the carrier material 30 is arranged between the carrier material 30 and the upper tool 16.
  • the element 32 is shown in one piece in the drawing. Of course, it is also conceivable, for example in the case of a push button, that the element 32 is made in two parts, one of the parts above and one of the parts below the carrier material 30.
  • the upper tool 16 is biased against the cam 10 by means of a spring 38.
  • a threaded rod 40 at the lower end of the lower tool 20 is used to adjust the pretensioning force of the spring 22.
  • An adjusting screw 42 is seated on the threaded rod 40, which adjoins a stop 44 and on which the spring 22 is supported.
  • the upper tool 16 is adjustable in length
  • the lower tool 20 is adjustable in length
  • / or the cam plate 10 is adjustable in height.
  • the upper tool 16 presses with maximum pressure against the element 32 arranged on the support table 28 of the lower tool 20 with the interposition of the carrier material 30, as a result of which the element 32 is deformed for attachment to the carrier material 30. Since the region 34 of the circumferential line of the cam disk 10 shown in the drawing below has a comparatively slight curvature, the pressure exerted changes very little in front of and behind the dead center, ie. H. the pressure lasts for a relatively long time and therefore allows the element to be deformed to flow during the application of the pressure.
  • the deformation pressure acting on the element 32 does not exceed the limit pressure that can be predetermined by adjusting the spring 22, which means that the same deformation pressure can always be used regardless of the carrier material.
  • the area 36 of the circumferential line of the cam plate 10 shown in the drawing above, which is assigned to the dead center, is only slightly curved, so that the upper tool 16, because of the prestressing against the cam plate emanating from the spring 38, causes the idling after the completion of the deformation process, i. H. cam no longer driven by the motor brakes to a standstill.
  • the region 34 of lesser curvature associated with the pressure dead center should extend over an angle of 10 ° to 25 °, preferably 15 °.
  • the region 36 of lesser curvature associated with the resting dead center should extend over an angle of 90 ° to 150 °, preferably 120 °.
