Definitions

  • the invention relates tov a ca rpet tufting machine of the type in which the tufting tools of individual machines are displaceable about a Vertical axis in a carrier head which can be lifted and lowered and which can be displaced in any desired direction in a horizontal plane.
  • the object o1" the present invention is to produce the same pattern efliciently on a number of carpets simultaneously with the minimum number of operatives, and to avoid the necessity for auxiliary personnel not trained in carpet tufting.
  • tufting devices of a carpet tufting machine having one or more displaceable tufting devices are movable in synchronism with other carpet tufting machines by connection means, so that the manual operation of one tufting device by the tufting operative simultaneously controls one or more tufting devices of other carpet tufting machines.
  • Mechanical, hydraulic, pneumatic or also electrical transmission means may be used for the positive control of the other tufting carrier heads.
  • the angular movement and the upand. down movement of the tufting devices mai7 be transferred by mechanical transfer means such, for instance, as shafts, to adjacent tufting devices, and such transmission means, for instance by means of lazy tong arrangements, may control the common longitudinal and lateral displacement of the tufting heads ina horizontal plane.
  • all angular movements of a tufting device are transmitted to one or more other tufting heads by electro-magnetic' control means.
  • the individu-al driving motors with the tufting devices coupled with one another are
  • adjustabley onthe guidingftufti-ng head, and-" also are adjustable on the other tufting heads to be put in or out of operation, so that, for instance, should a thread break, all the tufting heads have their operation simultaneously stopped until the thread is renewed, and all the tufting heads coupled together can then simultaneously operate further at the same place of the pattern.
  • the renewal of a thread can take place by known means, for instance it can be facilitated by the use of compressed air.
  • the invention has the advantage that only the tufting head acting as a control need be operated by a skilled carpet tufting operative, a watch over the running of the thread by auxiliary help alone being necessary by the coupling of the other tufting heads thereto.
  • Fig. 1 is a perspective diagrammatic View of two carpet tufting machines, the controls of which are coupled by mechanical means,
  • Fig. 2 is a side view of one of the two carpet tufting machines shown in Fig. 1 on an enlarged scale, the casing of the control element being partly in vertical section,
  • Fig. 3 is a vertical sectional view of the control arrangement for the same machine taken on a plane displaced by Fig. 4 shows another form of construction of a carpet tufting machine in side View with the cover plate of a housing foran electric trans- ⁇ mission apparatus removed,
  • Fig. 5 is a wiring diagram of Fig. 4 with the pivoted lever in horizontal section
  • Fig. 6 shows two carpet tufting machines coupled together, the control machine being of the type of Figs. 4 and 5.
  • the tufting carrier head l is carried at one end of a jib 3 which can swing in a vertical plane about the pivotal support 2, which jib carries at its opposite end the driving motor 4 mounted on a flange on it and acting as a counter-Weight.
  • the cheeks 5 forming a fork carrying the pivot spindle 2 are connected with the vertical shaft 'l by means of a plate which is revoluble within an intermediate casing 8, which in turn is revoluble Within the cylindrical housing 9 disposed on the end of the J'ib arm Ill.
  • the needle and the shears forming the tufting tools 60 are revolubly mounted in known manner about avertical axis inthe tufting carrier headk I andi arecontrolled by a handle H.
  • the tufting carrier head yI can be raised
  • the angular movement of the tuftingtools 6I)Vv about their common vertical axis is transmitted by sprocket wheels I3, I4, and bevel wheels I" and I6, from the ends of the ball jointedgtelescopically mounted shaft I1 and bevel wheels IB and I9 via bevel wheels 2IJ and 2I, 2I" to the shafts 23 guided in the tubes 22.
  • each shaft portion 23 between two adjacent housings 9 reverses the direction of rotation of the wheel I9 of the one housing with respect to that of the wheel I9 of the other housing.
  • Suitable means may be applied in order to cause rotary movement of the tools of all the machines in the same direction. This can be readily attained by alternately arranging in the series of the cooperating machines, a wheel I6 in the position shown in solid lines and a wheel I6 shown in dot and dash lines in Fig. 2.
  • the shaft 21 and the tube 22 encasing the shaft 23 serve simultaneously to transmit the movements given to the tufting carrier head in various directions in the horizontal plane. This is effected by the shaft 21 which transmits all movements to all the pivotal arms I0 about their supporting columns I2, while the rotary movement of the jibs about the vertical shaft 1 is transmitted by tube 22.
  • a bevel wheel 2S is mounted on the one end of each of the tubes 22, which mesh with bevel wheels 36 mounted on the hollow shafts 1.
  • the other end of each tube 22 is provided with a reversing gear which comprises a pair of bevel wheels 6I, 62 in mesh with a freely rotating third wheel 63 on opposite sides thereof, and the wheel 29 integral with the wheel 62 and in mesh with the wheel 36.
  • the shafts 1 and 23, as also the tubes 22, and the intermediate casing 8, are mounted to be freely revoluble on ball bearings, so that the minimum of power is necessary to operate the control from the handle II of one of the tufting arrangements.
  • Each of the machines comprises a main shaft 40 mounted on the jib 3, which drives the tufting tools -and is driven by van electric motor, viz motor 4 in machine A and motor 4 in machine B.
  • a tubular shaft 4I also driven by motor 4 rotates about the main driving shaft 40 at a higher speed than the latter, for which purpose a transmission is provided diagrammatically indicated at 4a in Fig. 6.
  • the electric motor 4 is shown larger than motor 4 in view of the fact that motor 4 has to furnish the power for the operation of the control devices in addition to the power for operating the tufting tools.
  • Disc magnets 36 and 31 are mounted on this high speed hollow shaft 4I.
  • Pinions 42, 43 freely revoluble on ball bearings on the shaft 4I are disposed between said disc magnets. Between these pinions a further disc magnet 44 is disposed which is revolubly mounted with respect to the casing 45 and is also carried on the hollow shaft 4I by means of a ball bearing. Pairs of disc armatures 46, 41 and 48, 49 are displaceably mounted by means of lateral bolts 36 on the pinions 42, 43, and abut against the side surfaces of the pinions 42, 43 against the action of spring discs 50.
  • the control lever 33 can thereby be operated with extreme precision, as only a minimum of force is necessary for its operation as is required by the pressure of the spring 35 to close contact 32.
  • is closed and the coil of the disc 31 is then energised to draw up the disc armature 48, 46 of the toothed wheel 43, and thereby a pinion 51 which engages with the pinion 43 directly without any intermediate wheel, so that the spindle 54 and the shaft 56 in this case are rotated in opposite directions.
  • the electrical wiring arrangement is shown in Fig. 5. As shown in this diagram, when at rest the current flows through the central disc coil 44 acting as a brake. Immediately the contacts 32 or 3
