Definitions

  • ABSTRACT A process and apparatus for producing a barbed spiral from a flat metallic barbed strip having a series of barbs and a supporting wire wherein the wire and metallic strip are combined in envelope rollers so that the wire is embedded into a flat metallic strip.
  • a reel At the output of the envelope rollers is a reel for winding the wire supported strip in convolutions so that every other barb of adjacent convolutions can be connected together to form a spiral fence when the assembly is opened in a longitudinal direction.
  • the invention includes a plurality of circumferentially spaced-apart clamping devices which are mounted on a rotary table which rotates synchronously with respect to the reel. There is provided a means for lowering the reel corresponding to the rise of the winding with respect to the rotary table and the output of the envelope rollers. Fingers are also provided for compressing the convolutions on the reel as they are being gathered.
  • This invention relates to a process and apparatus for producing a barbed spiral from a flat metallic barbed strip.
  • the strip envelops a supporting wire with portions of its strip surface by winding the barbed strip in convolutions juxtaposed in the longitudinal direction of the spiral on to a reel and connecting adjacent convolutions of the spiral at an uneven number of e.g. five points uniformly distributed over the periphery of the spiral so that in accordianlike manner, the spiral is extendable to a greater or lesser extent in the direction of its longitudinal axis (US. Pat. No. 2,908,484).
  • An object of the invention is to provide an automatic machine so that the manufacturing operations can be performed automatically in a single machine.
  • the invention not only relates to the purely mechanical combination of the individual known Working stations but also to a way of combining them so that several operations can be performed together in interaction.
  • the invention applies to the winding to fonn a spiral, and its connection to adjacent convolutions at five or seven points.
  • the connections are carried out on convolutions of the finished spiral so that the connecting members are each fitted at particular points in one row of the different layers, and alternate from row to row.
  • the combination of the steps of connecting with winding require a different operation, so that the convolutions to be connected are only engaged as they are being formed, and must be placed to such an extent that connection can take place.
  • an apparatus for performing the pro- 1 cess having delivery spool for the barbed strip, a delivery spool for the wire, and a pair of rollers for channelling the barbed strip so that the wire is received in channel rollers and enveloped with the barbed'strip.
  • a reel is provided for winding up the strip, and rotates continuously with the running speed of the strip with slippage.
  • a synchronously rotating rotary table surrounds the reel so that on the rotary table, there are disposed a number of radial clamping devices corresponding to the number of connecting member points for connection of the convolutions of the spiral. Since each of the five clamping devices only has to operate once 2 every two revolutions, there is adequate time for the connecting process to take place.
  • the winding capacity of the reel is an integral multiple of the spacing of the barbed strip portions carrying the barbs divided by the number of clamping devices.
  • the reel is formed by coaxially positioned web ribs which are distributed over its periphery in such a way that they engage in the gaps between the barbed strip portions carrying the barbs.
  • it is preferably to have the reel lowered corresponding to the rise in the winding in proportion to the rotary table and feed-in point.
  • FIG. 4 shows the winding of the connected spirals
  • FIG. 6 is an elevation view of the apparatus
  • FIG. 7 is an" elevation view of the clamping device
  • FIG. 8 is the clamping device in cross section
  • FIG. 10 shows a plan view of the clamping device with a connecting member feed
  • FIG. 4 When the formed barbed strip is wound onto a reel, it is wound into a spiral whose winding can be seen in FIG. 4.
  • a connection with connecting members 15 (of FIG. 3) is performed so that at every second connecting point of the five connecting stations, a connection takes place at each adjacent convolution on the next point of spacings I, II, III, IV and V. Therefore, convolutions l and 2 are connected together at spacings I, III and V, while convolutions 2 and 3 are connected together at spacings II and IV. In FIG. 4, this is shown up to convolution 10.
  • the automatic machine has a delivery spool 16 for the barbed strip which is supplied via a guide roller 17 to a pair of rollers 18 for channelling the barbed strip to form a channel.
  • the machine also has a delivery spool 19 for the wire which at exit 21, is fed laterally from above via a stumpet pipe 20 into the channel of the barbed strip.
  • Rollers 22 serve to envelop the wire with the barbed strip.
  • the formed barbed strip is supplied via a guide tube 23 to a reel 24 which continuously rotates with the running speed of the strip in rotational direction D.
  • the reel is driven together with rollers 22 e.g. by means of hydraulic motors which are supplied by a common oil pump.
  • rollers 22 e.g. by means of hydraulic motors which are supplied by a common oil pump.
  • rollers 22 By means of a choke in the intake to the hydraulic motor for rollers 22, there is a somewhat larger torque applied to the reel so that relative to the rollers 22, reel 24 rotates with slippage and draws the barbed strip from rollers 22.
  • the pair of rollers 18 is not driven.
  • the barbed strip is drawn through rollers 18 by rollers 22.
  • each two adjacent web ribs 27 are closely paired together in order to secure connecting members 15 between them to superimpose coated convolutions of the barbed strip. Facing the spacing of each pair of web ribs 27 is a clamping device 28 which is located on a rotary table 29 surrounding reel 24 and rotating synchronously therewith.
  • each clamping device 28 has two legs 30 with mountings 130 for connecting member 15 on the particular load arm, whose associated power arm 31 is located on the other side of a pivot 32 in each case.
  • an expanding lever 34 which at pivot 35 is supported in articulated manner to a fork 36.
  • Fork 36 is located at the end of a hollow piston rod 37 which can be extended and retracted by a piston 38 located in a cylindner 39.
  • a pressure medium such as compressed air can be applied to both sides of piston 38.
  • a projecting sliding bar 40 In the hollow piston rod 37 is located a projecting sliding bar 40 with a head 41. The underside of the head engages a spring 42 supported on fork 36.
  • Head 41 is fork-like and under the tension of spring 42, and is applied with its web fixed to sliding bar 40 between the converging area 131 of clamping device legs 31 so as to hold these apart.
  • On the forks of head 41 are also contained the bearings 32 for clamping device legs 30 and 31, and flanked on both sides by side plates 43.
  • the free front end of plates 43 embrace head 41 and form a collecting 30 jaw 44.
  • the clamping device is retracted by operating piston 39 on the piston rod side so that the above-described steps take place in the reverse sequence.
  • Connecting members 15 are in turn supplied to channel 52 from a magazine 54.
  • the connecting members are kept in stock in a plurality of magazine parts under spring tension in a systematic spatially correct position.
  • the maximum insertion depth of plunger 53 into channel 52 is set so that in the furthest extended position of clamping device 28 between the front end of plunger 53 and the final connecting member in channel 52, a gap is formed having the width of at least one connecting member so that a further connecting member can be inserted from below into the gap from magazine 54.
  • Connecting members 15 are sorted into the spatially correct symmetrical position in magazine 54 by means of a shaking and vibrating device.
  • each clamping device can also have a shaking and vibrating device which systematically supplies the connecting members to clamping device 28 from a nonsystematic store.
  • Finger 59 can pivot outwards and downwards about pivot 61 in a pawl-like manner. However, its upward pivotal movement is limited in the direction of the longitudinal projections of lever 57 by a fork stem 157.
  • the hold down device has two functions. Its first function is to keep the connecting member area of the clamping device free from barbed connected barbed spiral convolutions (FIG. 12). Thus, whenever the clamping device 28 associated with the hold down device has connected to the barbed spiral convolutions and has returned to its initial position, the hold down device swivels from its vertical position, into its horizontal position so that finger 59 engages in the winding circle of reel 24 and presses the two barbed spiral convolutions already connected in the connecting member plane downward on to the convolutions already connected in an earlier operation in order to form a dense layer of convolutions. i
  • the hold down device fulfills this function, in that after the clamping device is moved back, and the two previously connected convolutions are moved downward, finger 59 remains in the winding cricle of the reel until two further convolutions have been placed over it and the clamping device has been extended for connecting these convolutions and the convolutions that have been received in collecting jaw 44. Then while the clamping device remains in its extended position where the connecting process is perfomied, the hold down device pivots outwardly and upwardly so that finger 59 is removed resiliently and radially from the winding circle of thereel as a result of its pawl-like mounting. In order to fulfill the described spacing function, finger 59 has a certain thickness as shown in FIG. 12.
  • the automatic machine operates in the following manner:
  • clamping device 28 with its associated hold down device 55 on rotary table 29 closest to position 26, counter to rotation direction D, is designated I.
  • the following clamping device with its holding downdevice is designated as II and so on until V.
  • the timing diagram for clamping devices Z and hold down devices N is shown in FIG. 13. Clamping devices Z and hold down devices N are entered individually on the co-ordinate and the time in radians on the abscissa.
  • the connecting order for the particular clamping device takes place in a rotation angle position just behind feed-in point 25, and the order for moving the clamping device back in a rotation angle position about 90 takes place in front of feed-in point 25. Therefore the connecting operation can take place during a period of a little more than 180 radians. Since a connecting process always takes place only at every other spacing point, a particular clamping device only has to perform a connecting operation once per two rotations.
  • the control which does not form an object of the invention can take place in various ways e.g. in such a way that after the start of the strip is fixed to the reel, it is only necessary to give a single starting order. At the end of the winding process, a single stopping order is given so that all intermediate processes, particularly those after the first winding is completed take place automatically.
  • reel 24 After each full rotation, reel 24 is automatically lowered by an amount corresponding to the height of one winding e.g. by mounting the reel with a threaded spindle.
  • the uppermost winding laid by feed-in point remains in the correct relative position to the connecting member plane of clamping devices 28.
  • a process for producing a barbed spiral from a flat metallic barbed strip having a series of barbs and a sup- -,.x: rting wire comprising the steps of:
  • said connecting means comprises a plurality of circumferentially spaced-apart clamping devices corresponding in number to the number of connecting points for connecting the convolutions of the spiral.
  • the apparatus according to claim 4 additionally comprising a rotary table surrounding the reel and supporting said clamping devices, said table rotating synchronously with said reel.
  • the apparatus according to claim 6 comprising means for lowering the reel corresponding to the rise of the winding proportionally to the rotary table and the stationary output of the envelope rollers.
  • each finger is carried by a swivel arm and includes a spring catch with a top abutment so that upon swinging back,
  • winding capacity of the reel is an integral multiple of the spacing of the barbed strip portions carrying the barbs divided by the number of clamping devices.
