Definitions

  • the invention relates to a fur sewing machine of the type specified in the preamble of claim 1.
  • Fur sewing machines with a blowing device connected to a compressed air source for bending away the fur hair from the area of the seam to be formed are known in multiple configurations (DE-C 951 606, 2 024 284, 2 702 258 and 2 720 444, DE-A 2 065 037) .
  • the blowing device emits a compressed air flow or a plurality of compressed air partial flows in order to bend the fur hair of the sewing material away from the area of the seam to be formed, so that they are not sewn into the seam.
  • the compressed air escaping is usually perceived by the operating personnel as annoying and unpleasant as a cold draft and can even be the cause of illnesses.
  • FR-A 1 218 656 is a blowing device for fur sewing machines for bending away the fur hair of two fur strips to be sewn together along a common longitudinal edge from the region of this longitudinal edge by means of compressed air, which works in conjunction with a suction device and has a rod-shaped spreading tool which before the puncture point of the sewing needle protrudes transversely between the two fur strips and keeps them spread apart, the two fur strips resting against stops or an adjustable stop of the spreading tool running perpendicular to the sewing needle on the side of the common longitudinal axis from which the spreading tool onto the two fur strips protrudes to and through them.
  • At least one blowing nozzle is provided, which communicates with the interior of the hollow spreading tool in order to be pressurized with compressed air and to direct a compressed air flow into the gap between the two fur strips guaranteed by the spreading tool, namely from the side of the common longitudinal edge forth.
  • the suction device is arranged, which is intended to support the effect of the compressed air streams, in particular with regard to particularly long fur hair, and which has a suction box with lattice bars at the mouth facing the fur strips in order to prevent the fur strips from the suction box can be sucked in.
  • the air used in the blowing device can optionally be warmed, whereby it remains open for what purpose, to what temperature, at which point and in what way this air is to be warmed. Therefore, this proposal has not been taken up (see, for example, the fur sewing machines with blowing device according to DE-C 2 024 284, 2 702 258 and 2 720 444 and DE-A 2 065 037).
  • the invention has for its object to provide a fur sewing machine of the type specified in the preamble of claim 1, the heating device with a simple structure reliably ensures that the operating personnel is neither disturbed nor impaired health by the compressed air emerging from the blowing device .
  • the compressed air supplied to the blowing device is always heated to such a temperature by means of the extraordinarily simple heating device that after exiting the blowing device it does not give the operating personnel a draft and does not impair their well-being, nor does it affect their actual state of health.
  • the compressed air is preferably heated to a temperature between approximately 35 ° C. and approximately 60 ° C., so that after the outlet from the blowing device there is no such low compressed air temperature to which the human body would react sensitively.
  • the fur sewing machine 1 according to FIG. 1 is arranged on a horizontal table top 2 and is provided with two transport plates 3 and 4 and a blowing device 5.
  • the two transport plates 3 and 4 are in the same horizontal plane and can each be rotated about a vertical axis.
  • the inner transport plate 3 is attached to the upper end of a vertical shaft which is rotatably mounted in the housing of the fur sewing machine 1 and is driven intermittently.
  • the outer transport plate 4 is arranged to be horizontally movable in the direction of the double arrow 6 and is spring-loaded on the inner transport plate 3.
  • the two hairy sides of the two pieces of fur face each other and the two pieces of fur are pressed together at the two edges to be sewn together by the two transport plates 3 and 4 in order to move back and forth parallel to the double arrow 6 from above the two transport plates 3 and 4 To be pierced by the sewing needle of the fur sewing machine 1, which in cooperation with the gripper of the fur sewing machine 1 forms the seam connecting the two edges of the two pieces of fur.
  • the blowing device 5 with a blow pipe 7, which can be pivoted about a horizontal axis 8 between the operating position shown and a rest position, in which the blow pipe 7 is removed from the two transport plates 3 and 4 upwards.
  • the blowing device 5 is connected via a connecting line 10 to a compressed air source 11 in order to let a compressed air flow or several compressed air partial flows 12 emerge from the blow pipe 7 when pressurized with compressed air in the operating position according to FIG. 1, whereby the fur hair of the sewing material in FIG below between the two pieces of fur to be sewn together and from the two edges of which reach between the two transport plates 3 and 4.
  • a heating device 13 is provided for heating the compressed air supplied to the blowing device 5.
  • the heating device 13 has a pipe socket 14 through which the compressed air flowing in the connecting line 10 flows, which, if necessary, can be provided with external heat insulation and is equipped with a helical electrical heating resistor which extends in the pipe socket 14 from one end to the other, namely along an imaginary cylindrical surface coaxial to the pipe socket 14.
  • the compressed air source 11 is formed by a blower 15 which can be supplied with electrical current via electrical lines 16 and 17. Parallel to the blower 15, the heating device 13 or its helical electrical heating resistor is also connected to the two electrical lines 16 and 17.
  • An electrical switch 18 is provided in the electrical line 17, which is opened when the blowing device 5 or its blowing tube 7 is in the rest position, and which is then closed when the blowing device 5 or its blowing tube 7 is in the operating position 1 is pivoted.
  • the heating power of the heating device 13 is selected such that the compressed air supplied by the blower 15 assigned to the fur sewing machine 1, which has approximately room temperature, is heated to the respectively desired temperature between approximately 35 ° C. and approximately 60 ° C. If the compressed air temperature behind the heating device 13 should exceed a predetermined upper limit value due to malfunctions, an electrical thermal switch 19 opens automatically, which is connected in series with the heating device 13 or its helical electrical heating resistor in order to switch off the heating device 13.
  • the connecting line 10 of the fur sewing machine 1 can also be connected to a compressed air network, namely via an electromagnetic shut-off valve 20, which together with the compressed air network forms the compressed air source 11.
  • a compressed air network namely via an electromagnetic shut-off valve 20, which together with the compressed air network forms the compressed air source 11.
  • Fig. 3 which also shows that the electrical circuit for this compressed air source 11 and the heating device 13 is identical to that of FIG.
