Definitions

  • a measured length sensor for measuring the lengths of the material conveyed through the machine and an adjustable required length transmitter for controlling the length of material to be cut off are both connected to a comparison circuit which, as soon as the length U S Cl 72/l2 72,17 72/l31 sensed by the measured length sensor is equal to that to which the required length transmitter is adjusted brings the material to a standstill and operates the shearing device to cut off a length of the material.
  • the machine is also provided with adjustable number-0fcuts counter which, after each out has been made resets 83/69 BZlf 11/00 l References Cited the measured length sensor and thus causes the cycle UNITED STATES PATENTS of operations of the machine to be repeated until the number of cuts to which the number-of-cuts counter is adjusted is reached.
  • the conventional machines are provided, downstream of the straightening rollers, with mechanical stops which are adjustable in position longitudinally. When the leading end of the travelling material comes into contact with the mechanical stop, this brings the conveyor to a standstill and if desired automatically operates a shearing device.
  • a machine of this kind is described for example in the applicants Austrian Patent Specification No. 237,410.
  • this conventional means for stopping the conveyor and for operating the shearing device with the aid of mechanical stops is not suitable for use in the production of comparatively small batches of material of particular length.
  • a machine of this conventional kind is not capable, under these circumstances, of operating rapidly enough and reliably enough, because each time the cut-off length is changed the mechanical stop has to be readjusted in position and locked in place. This resetting of the machine often takes longer than the straightening and cutting off operation itself.
  • the object of the present invention is to provide a machine for straightening and cutting metal wire or metal strip into lengths, the machine being free from the disadvantages mentioned above and the adjustment necessary for cutting different lengths being able to be easily and rapidly effected.
  • a machine for straightening and cutting material in the form of metal wire or strip into lengths comprising a straightening device, a conveyor for conveying the material through the machine and a shearing device for cutting off lengths of the material, a measured length sensor for measuring the length of the material conveyed through the machine and an adjustable required length transmitter for controlling the length of material to be cut off, are both connected to a comparison circuit which, as soon as the length sensed by the measured length sensor is equal to that to which the required length transmitter is adjusted, brings the material to a standstill and operates the shearing device which cuts off a length of the material, the machine also being provided with an adjustable number-of-cuts counter which, after each cut has been made, resets the measured length sensor, causing the cycle of operations to be repeated until the number of cuts to which the number-of-cuts counter is adjusted is reached.
  • the machine further comprises a programming system including a number of independent required length transmitters and an equal number of independent number-of-cuts counters, the individual transmitter and counter pairs, each pair consisting of one required length transmitter and one number-ofcuts counter, being arranged to be energised one after the other, the programming system being arranged in such a way that as soon as the number of cuts made reaches that to which one number-of-cuts counter is adjusted, this counter and the transmitter in the pair are disconnected and the next pair are energised.

  • This form of the invention makes it possible to programme a production run in which a whole series of batches of different lengths are straightened and cut, each batch containing a required number of pieces all of the same length, the lengths being, however, different in the different batches.
  • the machine Once the machine has been started it goes through the entire programme automatically without any further attention by the operator. It may pull the material off a storage reel and it then straightens and cuts, entirely automatically, the required series of batches of cut-off material the batches having different lengths from each other.
  • FIG. 1 is a front view of the machine
  • FIG. 2 is a front view of further parts of the machine shown in FIG. 1, these parts not being visible in FIG. 1 because they are situated behind the front of the machine;
  • FIG. 3 is a circuit diagram'of the control system of the machine.
  • FIG. 4 is a circuit diagram of a programming system for the machine.
  • the material which is to be straightened and cut off into lengths advances through the machine in the direction of an arrow P along a horizontal path A-A.
  • the material is conveyed by a conveyor formed by two pairs of motor-driven driving rollers 1, 2.
  • the lower pair of driving rollers 2 can be raised and lowered, relative to the upper pair 1.
  • a thrust spring 3 When the machine is operating the lower pair of rollers 2 is thrust upwards towards the upper pair I by a thrust spring 3,
  • the spring 3 is mounted on a sliding pull rod 5. At its lower end the spring 3 thrusts against a guide plate 4 fixed to a frame of the machine. The upper end of the spring 3 thrusts against a cross beam 6 to which the upper end of the rod 5 is fixed.
  • the rod 5 slides up and down in a hole through the guide plate 4, raising and lowering the cross beam 6.
  • Bearings 20 for the two driving rollers 2 are fixed to the two ends of the cross beam 6, the arrangement allowing the lower pair of driving rollers 2 to be adjusted in position vertically.
  • the two pairs of driving rollers l and 2 are driven by an electric motor 11.
  • Worms 13 and 14 are keyed to a driving shaft 12 of the motor and these worms mesh with the:worm wheels 15, 16.
  • One worm wheel 15 is coaxial with and fixed to one of the upper driving rollers l and the other worm wheel 16 is coaxial with and fixed to one of the lower driving rollers 2.
  • the other two driving rollers are driven through V-belts l7 and 18.
  • the mechanism for raising and lowering the lower pair of driving rollers 2 is arranged as follows.
  • the lower end of the rod is pivotally attached to a lever 7, which is itself pivotally mounted at one end 8 on the frame of the machine.
  • the other end of the lever 7 is pivotally connected to the lower end of a piston rod 9 the piston of which slides in a pivotally mounted pneumatic cylinder 10.
  • Compressed air supplied to the cylinder 10 moves the piston rod 9 downwards, rocking the lever 7 about its pivoted end 8 so that the sliding rod 5 is moved downwards against the action of the spring 3.
  • a straightening device 20 Just upstream of the driving rollers l, 2 there is a straightening device 20.
  • Lower rollers 2i of this device are rotatably mounted in bearings fixed to the frame of the machine.
  • Upper rollers 22, on the other hand, are adjustable in position vertically.
  • the bearings of the upper straightening rollers 22 are connected to a lever 23 pivoted at one end 24 to the frame of the machine.
  • An eccentric 25 acts on the other end of the lever 23, to rock this lever up or down about its pivoted end 24. This arrangement allows the upper straightening rollers 22 to be adjusted in position vertically relative to the lower straightening rollers 21.
  • the system for cutting the material into lengths is arranged as follows: the electric motor 11 drives a flywheel 27 through a V-belt 26.
  • the flywheel 27 is coupled by a pneumatic coupling 28 to an eccentric 29, which is merely indicated in FIGS. 1 and 2 of the drawings.
  • the eccentric 29 drives a connecting rod 30 which actuates a shearing device 31.
  • An electro-pneumatic valve 32 (H6. 1), controlled as will be described later, controls the admission of compressed air to the cylinder 10, for lowering the lower pair of driving rollers 2 and also controls the engagement of the coupling 28 for actuating the shears 3i.
  • the sensor 35 Downstream of the two pairs of driving rollers 1 and 2 there is a measured length sensor 35 which senses the advancing movement of the material.
  • the sensor 35 has a measuring wheel 36 mounted on an arm which is pivoted about a vertical axis 37.
  • a spring not shown, thrusts the measuring wheel 36 against the surface of the travelling material so that the measuring wheel is rotated by the moving material.
  • the measuring wheel 36 drives a pulse transmitter disc 38a.
  • the rim of the disc 38a moves between the arms of a pulse transmitter fork 38.
  • the rim of the disc 38a can for example have slots or teeth.
  • the pulse transmitter fork 38 can be constructed, for example, as a photoelectric or a magnetic sensor.
  • the number of pulses sent out by the pulse transmitter fork 38 is proportional to the distance of advance of the material.
  • the pulses from the pulse transmitter fork 38 are transmitted to a pulse divider 39.
  • the mode of operation of the pulse divider 39 is as follows: let it be assumed that the material is to be cut off into lengths each of which is a whole number of centimetres and that the tolerated error in length is 0.25 cm. Under these circumstances the pulse transmitter fork 38 which forms a measured length transmitter, must deliver four pulses for each centimetre of advance.
  • the pulse divider 39 divides the pulses in the ratio 4 l.
  • the pulses delivered by the pulse transmitter fork 38 to the pulse divider 39 are therefore accurate within the tolerated 0.25 cm, four pulses being delivered for each 1 cm of advance of the material.
  • the pulses delivered by the pulse divider 39 represent the specified distance of advance in centimetres.
  • the pulses delivered by the pulse divider 39 are transmitted to a pulse counter 40 which is connected to a comparison circuit 41 which is itself connected to a required length transmitter 42 which is adjustable.
  • the adjustment of the required length transmitter 42 determines the length of the cut-off piece of material.
  • the arrangement functions as follows. As soon as the material -has advanced the desired distance, corresponding to the setting to which the required length transmitter 42 has been adjusted, the comparison circuit 41 delivers a signal, through a conductor 43, a cut counter 44 and a power stage 45, to a cut commander 46, which can for example take the form of an energising coil of the electro-pneumatic valve 32.
  • the cut commander 46 On receiving this signal the cut commander 46 by sending a com mand to the compressed air cylinder 10, brings the material to a standstill and also, engaging the pneumatic coupling 28, operates the shears 31, cutting the material.
  • the cut counter 44 also delivers, through a feedback conductor 47, a resetting signal to the pulse counter 40, starting a further operational cycle in which the material is advanced through a further measured distance.
  • the cut counter 44 is connected to a number-of-cuts transmitter 48, which is adjustable by the operator. By adjusting the number-ofcuts transmitter 48 the operator determines the number of cut-off lengths of material he wishes the machine to produce in a given batch, the length of each piece of material being determined by the setting of the required length transmitter 42.
  • the number-of-cuts transmitter 48 determines the number of pieces cut, whereas the required length transmitter 42 determines the length of each piece.
  • the pulse counter 40 is repeatedly reset by the consecutive cut counter 44, which counts the cuts made, the cycles being repeated until the number of cuts preset on the number-of-cuts transmitter 48 is reached, whereupon the electric motor 11 is switched off, for example through a conductor 49 and/or the lower pair of driving rollers 2 is lowered, bringing the travelling material to a standstill.
  • the programming system contains a number of required length transmitters 42 which can be individually 'preset to the required cut-off lengths, and an equal number of number-of-cuts transmitters 48 which can be individually preset to the required number of pieces in each batch. All the required length transmitters 42 are connected in common through individual relay switches 50 to the comparison circuit 41. Similarly all the number-of-cuts transmitters 48 are connected in common through indi vidual relay switches 51 to the cut counter 44. Each controlling pair of transmitters consisting of a required length transmitter 42 and a number-of-cuts transmitter 48, is connected by simultaneous closing of the relevant switches 50 and 51 in the programming system. In the example shown the required length transmitter 42a is connected through the switch 50a to the comparison circuit 41 and the number-of-cuts transmitter 48a is connected through the switch 51a to the cut counter 44.
  • the programming system functions as follows: when the machine is in operation, the material travels forwards along the path AA and as soon as the comparison circuit 41 detects that the distance travelled is equal to the required length, the comparison circuit 41 delivers a pulse through the conductor 43 to the consecutive cut counter 44, which stops the advance of the material and energises the cut commander 46, actuating the shearing device 31 and cutting the material.
  • the cycle is repeated, successive lengths of material being cut until the number-of-cuts transmitter 48 detects that the required number of lengths of material have been cut for the batch, whereupon a command signal is delivered, for example through the conductor 49, which closes the next relay switch in the chain of consecutively actuated switches.
  • the two controlling transmitters 42 and 48 are disconnected and a different pair of controlling transmitters are connected for the cutting of a further batch of material, the cycle being repeated until the entire programme of batches has been cut.
  • the required length transmitter, the measured length sensor, the number-of-cuts transmitter and the cut counter can for example be in the form of four-pole mechanical switches of the kind which have a counting function, particularly pulse controlled step switches.
  • mechanical switches instead of mechanical switches, electronic switches are preferably used, for example in the form of chain counters or the like.
  • the example described can be modified in various ways, for example two or more straightening devices can if desired be arranged to operate in parallel with each other, the straightening devices both feeding to a common shearing device. All the straightening devices are then controlled by a common measuring and controlling system, the whole being arranged so that material from two or more production lines is simultaneously cut into lengths.
