Description
A CUTTING MACHINES This invention relates to a cutting machine.
2332386 Cutting machines of a type comprising a reciprocating blade and a ultrasonic horn which is caused to oscillate at ultrasonic frequencies, for cutting pieces, for example, labels from a strip of material, are known. The strip of material is positioned between the blade and the horn and the blade is then caused to move towards the horn for cutting the strip of material. Energy from the vibrating horn is concentrated by the cutting edge of the blade and transferred to the strip of material thereby cutting it. The blade is then retracted from the horn, and the strip of material advanced a predetermined distance which will determine the length of the cut piece. As such, the strip of material is positioned so that the next piece can be cut therefrom. A disadvantage of cutting machines of this type is that the strip of material can only be advanced once the blade has been' retracted. Consequently, the strip of material is advanced in a start/stop manner which is time consuming as this limits the speed at wNch the strip of material can be cut into pieces.
The start/stop advancement of the strip of material causes wear and tear on mechanical components of the drive of such cutting machines. Furthermore, the reciprocating motion of the cutting blade inevitably involves contact between the blade and the horn which wears the cutting edge of the blade and marks the horn. As such, the cutting edge of the blade may require sharpening, while the working surface of the horn may require grinding for removing marks caused by the cutting blade. As a result, the relative positions of the cutting blade and the horn will require re-adjustment before further cutting can commence.
1 Such cutting machines are often required to be used together with other continuous processes, for example, a continuous label printing process wherein the cutting machine is used for cutting the labels, with the result that the start/stop cutting operation performed by such cutting machines limits the overall productivity of such otherwise continuous processes.
It is an object of the present invention to provide a cutting machine that ameliorates many of the problems associated with known cutting machines as described hereinabove.
According to the invention, there is provided a cutting machine for cutting a strip 10 of material, comprising a blade having a cutting edge; an ultrasonic horn; feed means for advancing the strip of material between the cutting edge of the blade and the horn; and displacement means for displacing the blade for moving the cutting edge momentarily into cooperating relationship with the horn in synchronisation with and at the same velocity as, the advancement of the strip of material, for transversely cutting the strip of material.
The displacement means of the cutting machine may include a driven rotor to which the blade is mounted, the-rotor being rotatable about an axis of rotation, thereby to provide for rotational displacement of the blade and consequently the cutting edge thereof into said co-operating relationship with the horn for cutting the strip of material.
The blade may be mounted to the rotor in an arrangement wherein the cutting i i edge of the blade is disposed parallel with respect to the axis of rotation of the rotor.
The rotor may include an adjustable mounting arrangement for mounting the blade to the rotor in an arrangement wherein the position of the blade is adjustable thereby to permit adjustment of the position of the cutting edge of the blade relative to the axis of rotation of the rotor.
The mounting arrangement of the motor may include urging means that acts between the blade and the rotor for urging the blade such that the cutting edge of the blade is urged away from the axis of rotation of the rotor, and releasable clamping means for releasably clamping the blade to the rotor.
The urging means of the mounting arrangement may be in the form of a spring.
The cutting machine may include synchronising means for synchronising the velocity of the strip of material with the velocity of the cutting edge of the blade at the moment when the cutting edge is moved into said cooperating relationship with the horn.
The cutting machine may be used for cutting pieces from a strip of material having printed matter printed thereon in a repeating pattern. In this case, the cutting machine may include a variable speed electric motor for driving the rotor and the synchronising means may include an optical sensor for sensing a predetermined feature of the repeated printed matter. As such, the synchronising means may include programmable processing means that is linked to the optical sensor and the electric motor, thereby to synchronise the speed of rotation of the rotor and'the position of the cutting edge of the blade with the position of the repeated printed matter on the strip of material and the speed of advancement of the strip of material, for ensuring that the strip of material is cut at opposite sides of the printed matter.
The electric motor may be operable to cause rotation of the rotor at a speed which provides for the cutting edge of the blade to move at the same speed as the speed of advancement of the strip of material when the cutting edge is momentarily moved into said cooperating relationship with the horn, and at an accelerated speed for accelerating the movement of the blade after a cutting operation, to a predetermined position before the next cutting operation commences.
It will be appreciated that the exact configuration of the cutting machine may vary while still incorporating the essential features defined hereinabove. In particular, the Applicant envisages that the cutting machine may include two or more blades.
Further features of a cutting machine in accordance with the invention are described hereinafter by way of a non-limiting example of the invention, with reference to and as illustrated in the accompanying diagrammatic drawing.
Figure 1 is a schematic front view, partly in section, of a cutting machine in accordance with the invention; Figure 2 is a schematic top view, partly in section, of the cutting machine of Figure 1; Figure 3 is an enlarged fragmentary schematic side view of the rotor having the cutting blade mounted thereon, and the ultrasonic horn of the cutting machine of Figure 1; and Figure 4 is a schematic block diagram illustrating the manner in which the synchronising means of the cutting machine of Figure 1, operates.
In the drawings, reference numeral 10 designates a label cutting machine for cutting labels off a strip of woven polyester material 11. The cutting machine is adapted for use in cutting labels in the form of printed matter in repeating pattern, from the strip of material 11 and includes a frame 12, a piezoelectric ultrasonic horn 14 and a rotor 16.
The rotor 16 includes an integral shaft 18 that is supported by bearings 20, on the frame 12. The rotor 16 and the shaft 18 are thus rotatable with respect to the frame 12 about axis of rotation designated by the reference numeral A.
The cutting machine includes a flat blade 22 having a cutting edge 24. The blade 22 is mounted to the rotor 16 in an arrangement wherein the cutting edge 24 of the blade 22 is disposed parallel with respect to the axis of rotation A of the rotor. The rotor 16 includes an adjustable mounting arrangement for mounting the blade to the rotor. As such, the rotor 16 defines a slot 26 that extends, depth-wise, radially inwardly and in a direction that is parallel to the axis of rotation A.
The rotor defines a pair of bores 28 in the base of the slot 26 that lead radially inwardly from the slot 26. The adjustable mounting arrangement includes urging means in the form of a coil spring 30 that is seated in each bore 28, one end of which protrudes from the bore.
The blade 22 is in the form of a flat plate 24 that is seated on the protruding ends of the pair of coil springs 30 in the slot 26 in an arrangement wherein an edge region of the blade protrudes from the slot 26. The protruding edge region includes the cutting edge 24 of the blade.
The rotor 16 defines three holes 32 that extend into the slot 26. The holes 32 are internally threaded. There is a cap screw 34 in each of the holes 30, the external threading of each cap screw 34 being complementary with, and engaging with, the internal thread of its respective hole 32. As such, the cap screws 34, when tightened, releasably clamp the blade with respect to the rotor.
The cutting machine includes a variable speed electric motor 36 that is directly coupled to the rotor 16 by means of a coupling arrangement designated generally by the reference numeral 38.
1 The cutting machine 10 further comprises a feed mechanism designated generally by the reference numeral 40, for advancing the strip of material 11 between the rotor 16 and the ultrasonic horn 14. The feed mechanism 40 comprises a pair of nip rollers 42 between which rollers the strip of material is fictionally advanced via rotation of the rollers. The rollers 42 are each mounted at the ends of shafts 44 that are rotatably mounted on the frame 12 via bearings 46. One of the rollers 42.1 is driven at a constant speed via an electric motor 48, while the other roller 42.2 is an idler roller that is caused to rotate in unison with the driven roller 42.1 due to its frictional engagement therewith.
In order to cut labels from the strip of material 11, the cutting edge 24 of the blade 22 is rotated momentarily into co-operating relationship with the horn 14 in synchronization with the advance of the strip of material for cutting the strip along its width. The cutting machine includes synchronising means for, synchronising the velocity of the strip of material 11 with the velocity of the 15 cutting edge 24 of the blade 26 at the moment when the cutting edge is moved into co-operating relationship with the horn. As such, the synchronising means. includes an optical sensor 50 that senses a predetermined feature of the repeated printed matter printed on the strip of material. The synchronising means further includes processing means in the form of a programmable processor 52 that is 20 linked to the optical sensor 50 and the electric motor 36 for controlling the speed of rotation of the rotor 16 and consequently the cutting edge of the blade, thereby to synchronise the speed of rotation of the rotor and the position of the cutting edge of the blade with the position of the repeated printed matter on the strip of material and the speed of advancement thereof, so as to ensure that the 25 strip of material is cut at opposite sides of the printed matter to form labels. The operation of the processor 52 is controlled by computer software.
The electric motor 36 is operable to cause rotation of the rotor 16 at a speed which provides for the cutting edge of the blade to move at the same speed as the speed of advancement of the strip of material when the cutting edge is momentarily moved in said co-operating relationship with the horn 14, and at an 1 accelerated speed for accelerating the movement of the blade after a cutting operation, to a predetermined position before the next cutting operation commences. The electric motor 36 is linked to the processor 52 and its operation is controlled thereby.
Before the cutting machine 10 can be used, it is set up by positioning the blade 32 with respect to the rotor 16 and the ultrasonic horn 14. In order to position the blade 22, the rotor 16 is rotated so that the blade 22 is positioned opposite the ultrasonic horn 14. In Figure 3, the blade 22 in the centre is shown in this position. The cap screws 34 are loose at this time. The springs 30 force the blade 22towardsthe ultrasonic horn 14so thatthe cutting edge 24 contacts the horn. The cap screws 34 are then tightened against the side of the blade 22 thus forcing the blade against the opposite wall of the slot 26, thereby clamping the blade in place.
In use, the ultrasonic horn 14 vibrates while the rotor 16 is rotating with its shaft 18. As mentioned above, the strip of material is advanced by the feed mechanism 40 between the rotor 16 and the ultrasonic horn 14. As the rotor 16 is caused to rotate the blade 22 moves past the ultrasonic horn 14, with the strip of material being advanced between the cutting edge 24 of the blade 22 and the horn 14. As a result of the positioning of the blade 22 with respect to the rotor 16 and the horn 14 as described above, each cutting edge 24 moves close enough to the 14 just to "kiss" it as the blade 28 of which it forms a part, moves past the horn. Energy from the vibrating horn 14 is concentrated by the cutting edge 24 of the blade, adjacent thereto, and a piece is thus severed from the rest of the strip of material by the interaction of the cutting edge with the horn.
Synchronisation of the speed of advancement of the strip of material and the speed of rotation of the rotor 16, ensures that the tape is advanced in synchronisation with the rotation of the rotor 16. Thus, the speed at which the strip of material passes the horn 14 is the same as that of the cutting edge 24 in a direction parallel with the direction in which the strip moves past the horn 14.
As the cutting edge of the blade is caused to move past the horn 14 in the same direction and at the same speed as the speed of advancement of the strip of material, the cutting edge merely "kisses" the surface of the vibrating horn. This significantly reduces wear and tear on the cutting edge and the surface of the horn. Particularly in the case of a strip of a woven or knitted material, conventional label cutting machines tend to fray the cut ends of such labels, whereas the cutting machine in accordance with the invention does not. This is explained by the fact that as the cutting edge of the cutting blade approaches the horn, the cutting edge is brought into contact with the strip of material which effectively welds the material immediately prior to cutting it. The wiping action of the blade against the horn effectively smears the fibres of the strip of material against the horn and cuts the strip, in the process fusing or welding the fibres to one another. As such labels produced by the cutting machine have "nonscratchy" unfrayed edges. Three positions of the cutting blade are illustrated in Figure 3 of the drawings, with the blade positions being shown immediately before cutting commences, while cutting is in progress and immediately after cutting has been completed.
The cutting machine in accordance with the invention, permits the strip of material to be cut while being advanced continuously. This feature allows the cutting machine to be effectively used in continuous processes such as a continuous label printing process.
Once a piece has been cut from the tape, the blade 22 moves away from the horn 14 as the rotor 16 rotates, in so doing flicking the cut label for stacking in, for example, a container in which the labels are stacked. This flicking action assists the stacking of the labels.
