Fence mesh forming machine
View Patent ↗A machine for making a knotted wire fence, including a machine frame, at least one knot box, at least one drive shaft, and a drive shaft driving means, wherein the machine can be switched between a first configuration in which the machine can be used to produce a knotted wire fence incorporating a first knot type, and a second configuration in which the machine can be used to produce a knotted wire fence incorporating a second knot type.
1. A machine for making a knotted wire fence incorporation either a first knot type or a second knot type, said machine comprising:
a machine frame including a knotting bed for supporting a series of spaced parallel wires;
a plurality of driveshafts each of which extends across said knotting bed;
each driveshaft having at least one knot box mounted thereon;
a driveshaft driving means driveably connected to said driveshafts;
wherein said machine is switchable between:
a first configuration in which each of said knot boxes is configured to produce said first knot type and in use the machine produces a knotted wire fence incorporation said first knot type;
and a second configuration in which each of said knot boxes is configured to produce said second knot type and in use the machine produces a knotted wire fence incorporation said second knot type;
said second knot type being different from said first knot type.
2. The machine according to claim 1 , wherein the first knot type is a stay knot and the second knot type is a fixed knot.
3. The machine according to claim 2 , wherein the drive shaft driving means is configured to drive each of said plurality of drive shaft in a rotary motion.
4. The machine according to claim 1 , wherein the drive shaft driving means is configured to drive the or each drive shaft in a rotary motion.
5. The machine according to claim 4 , wherein said plurality of drive shafts comprises four drive shafts.
6. The machine according to claim 5 , wherein the drive shaft driving means is a series of rotary servo motors and a controller, and wherein in switching the machine between the first configuration and the second configuration, the controlled is controlled by a programme which is switched between a first knot drive programme and a second knot drive programme.
7. The machine according to claim 6 , wherein in switching the machine between the first configuration and the second configuration, the position of the drive shafts is not changed.
8. The machine according to claim 5 , wherein the drive shaft driving means is a mechanical motion control consisting of a rotary gear box for converting a rotary input into the required timed motion of the drive shafts, and wherein in switching the machine between the first configuration and the second configuration, said at least one knot box, in the form of a first knot rotary gear box is removed and replaced with a second knot rotary gear box.
9. The machine according to claim 8 , wherein in switching the machine between the first configuration and the second configuration, the position of the drive shafts is not changed.
10. The machine according to claim 4 , wherein the drive shaft driving means is a series of rotary servo motors and a controller, and wherein in switching the machine between the first configuration and the second configuration, the programme on the controller is switched between a first knot drive programme and a second knot drive programme.
11. The machine according to claim 10 , wherein in switching the machine between the first configuration and the second configuration, the position of the drive shafts is not changed.
12. The machine according to claim 4 , wherein the drive shaft driving means is a mechanical motion control consisting of a rotary gear box for converting a rotary input into the required timed motion of each of said the drive shafts, and wherein in switching the machine between the first configuration and the second configuration, said at least one knot box is a first knot rotary gear box, whichh is removed and replaced with a knot box which is a second knot rotary gear box.
13. The machine according to claim 12 , wherein in switching the machine between the first configuration and the second configuration, the position of the drive shafts is not changed.
14. The machine according to claim 1 , wherein in switching the machine between the first configuration and the second configuration, the position of the drive shafts is not changed.
15. The machine according to claim 1 , wherein in the first configuration said at least one knox is a first knot box configured to produce a stay knotted wire fence, and wherein in the second configuration said at least one knot box is a second knot box configured to produce a fixed knotted wire fence.
