Description
- The present invention relates to an automatic machine for taping and cutting continuous bundles of fibres, particularly natural and artificial textile fibres. These operations are necessary in order to insert bundles of fibres into the containers used for their transportation. More specifically such automatic machine has the features disclosed in the precharacterising portion of claim 1.
- WO-A-8501266 discloses a device for applying a strip closure around an envelope having such features. This device comprises a support frame with a slot, a bracket and a rotor having peripheral recesses disposed on both sides of the slot. In operation the envelope is inserted in the slot and received into one of the recesses of the rotor, wherein the taping takes place. This device is conceived for hand use and is not suitable for application in automatised industrial processes.
- The object of the present invention is to provide an automatic machine for taping and cutting continuous bundles of fibres, which is easy to use, very reliable and suitable for use in automatised continuous processes.
- The subject of the present invention is constituted by a machine of the type indicated above, having furthermore the features set forth in the characterising portion of claim 1.
- Advantages and characteristics of the present invention will become clear from the detailed description which follows with reference to the appended drawings, provided by way of non-limiting example, in which:
- Figure 1 is a perspective view of a machine according to the invention,
- Figure 2 is a schematic sectional view taken on the line II-II of figure 1,
- Figures 3 to 5 are schematic perspective views of some parts of the machine according to the invention during different operating stages, and
- Figure 6 is a perspective view of a bundle of fibres cut by the machine.
- An automatic machine (Figures 1 and 2) for cutting and taping continuous bundles of
fibres 3 comprises asupport frame 2 constituted by a plurality of parallel vertical walls 4 formed with a substantiallysemicircular slot 6 into which the bundle of fibres is passed, as will be described in further detail below. - The
support frame 2 is preferably made of metallic material with a very smooth surface, which prevents damage the fibres during operation. - Means for moving the
bundle 3 are mounted about apin 8 fixed to theframe 2. These comprise twomain arms 10 each of which has oneend 12 hinged on thepin 8 and a hook-shapedopposite end 14. Eachmain arm 10 has an associated pair ofauxiliary arms 16 each having one end 18 hinged on thepin 8 and an opposite U-shaped end whose concavity is opposite that of the hookedend 14 of themain arm 10. Thearms electric motor 21 through a chain transmission mechanism of known type. Moreover, pins 25 and 27 project from theframe 2 for stopping thearms main arms 10 and theirauxiliary arms 16 are arranged symmetrically of the longitudinal median plane of the machine. -
Cogwheels 22,taping levers 24,cutting levers 26 and compactinglevers 28 are also mounted in pairs symmetrically of the longitudinal median plane (Figures 3 to 5). - A portion of the periphery of each
cogwheel 22 extends within theslot 6 and faces arespective taping lever 24. The two cutting levers 26 and the two compactinglevers 28 are mounted downstream of thecogwheels 22 and thelevers 24, and face each other on opposite sides of theslot 6. - Each of the two cogwheels, which are both freely rotatable on the
same spindle 30, has a series ofperipheral teeth 32 andnotches 34 and supports a respective length ofadhesive tape 36 unwound from arespective reel 38 supported by theframe 2. Bothreels 38 are mounted so that the adhesive side of thetape 36 faces upwards with reference to Figures 1 to 5. - Each
taping lever 24 is hinged on afirst pin 40 and has a shapedactive end 42 facing therespective cogwheel 22 on the opposite side of theslot 6, itsopposite end 44 being subject to the action of resilient biassing means 46. - Each
cutting lever 26 is hinged on asecond pin 48, has an operatingend 50 which projects into the slot downstream of the associatedcogwheel 22, and has anopposite cutting end 52 which is upstream of the operatingend 50 and is subject to the action of resilient biassing means 54. Thecutting end 52 has a suitably-shaped and interchangeable blade. - Each compacting
lever 28 is hinged on athird pin 56 and has an operatingend 58, itsopposite end 60 being subject to the action of resilient biassing means 62. Each compactinglever 28 also has aconvex projection 64 which, as will be described in further detail below, is intended to face a correspondingly-shaped recess 66 in therespective cutting lever 26. - A circular
rotary blade 68 is mounted in the longitudinal median plane of the machine, is driven by a motor and extends into theslot 6 downstream of thecutting levers 26 and thecompacting levers 28. Theblade 68 is driven by an electric motor, not shown, and its position relative to theframe 2 is adjustable so that its projection into theslot 6 can be varied. - When the machine is in operation, the bundle of
fibres 3 is positioned near theframe 2 by a supply device of known type, not shown (Figures 1, 2 and 3). Themain arms 10 are rotated by themotor 21 and capture thebundle 3 with theirhooked ends 14, thrusting it against the U-shapedends 20 of theauxiliary arms 16. - These are then also rotated by the
motor 21. Thebundle 3 is thus clamped between the opposite concavities of the distal ends of themain arms 10 and theauxiliary arms 16 and is drawn into thesemicircular slot 6 by their rotation. - Here (Figure 4) the
bundle 3 enters anotch 34 in the periphery of eachcogwheel 22 and traps therein a respective length oftape 36 which adheres to the portion of thebundle 3 which is radially inward of thecogwheel 22. Theshaped end 42 of eachlever 24 turns over the respective end portion of thetape 36 situated downstream of thebundle 3, thus also wrapping the portion of thebundle 3 which is radially outward of thecogwheels 22. Two spaced-apartperipheral portions 74 of thebundle 3 are thus completely wrapped in theadhesive tape 36. - As the bundle continues to move in the
slot 6, it interferes (Figure 5) with theoperating ends 50 of thecutting levers 26 which pivot about thepins 48, causing theircutting ends 52 to enter theslot 6 and cut theadhesive tapes 36 in positions upstream of thebundle 3. - As they pivot, the
cutting levers 26 also cause the associatedcompacting levers 28 to rotate by interfering with theiroperating ends 58. Theconvex projection 64 of eachlever 28 is thus positioned opposite thecorresponding recess 66 in therespective cutting lever 26 and the respectiveperipheral portions 74 of thebundle 3, which are wrapped in theadhesive tape 36, are trapped between them and hence compacted. - Conveniently, the resilient biassing means 46, 54 and 62 return the
respective levers - Finally, as it continues to move in the
slot 6, thebundle 3 comes into contact with therotary blade 68 which cuts it between the two tapedperipheral portions 74. Two pieces of the bundle, taped at their facing ends, are thus produced (Figure 6) and, under operating conditions, one of these is a piece whose opposite end has already been taped during the previous operating cycle of the machine, whilst the other is the end of a continuous bundle which will be divided into several pieces during the subsequent operating cycles of the machine. - The two pieces of the
bundle 3 produced by the cutting continue to be entrained by thearm main arms 10 meet therespective stop pins 25, whilst theauxiliary arms 16 rotate still further before being stopped by electrical travel stops. - The pieces of the
bundle 3 are thus released from thearms - At this point, the
arms motor 21, in the opposite sense from that in which they rotated previously. This movement finishes when theauxiliary arms 16 are stopped by thepins 27 and themain arms 10 are stopped by electrical travel stops. The machine is thus ready to carry out a new operating cycle. - Naturally, the principle of the invention remaining the same, the details of construction and forms of embodiment may be varied widely with respect to those described and illustrated purely by way of example, without thereby departing from its scope.
