Definitions

  • a traveling head cutting press is provided with light-responsive control means operative in accordance with the movements of the operator, without necessitating diversion of the operators attention from work manipulation, for initiating platen'movement of translation, either in initiating cutting strokes in response to withdrawal of the operator's hands from the danger zone or in causing traverse movement with the head in following the die placement area along the work.
  • the control means is operative to terminate the platen movement automatically.
  • Such presses can be and often are equipped with a die-carrying platen and controls for causing the platen to cycle continuously, moving in sequenced cutting strokes across the width of the workpiece.
  • the circumstances of a large share of die cutting makes it desirable that the operator exercise discretion in locating die-cutting means on the work. Examples include dieing out parts of different sizes involving frequent die changes, nesting of the parts and dieing out parts from workpieces of nonuniform character. Accordingly, in using such cutting presses, it has been common.
  • Such cutting is often referred to as semiautomatic because it involves manipulation of the work by the operator in each cutting cycle.
  • the machine itself may be equipped with control means for continuous cycling with programmed delays, for example as disclosed in the above-mentioned patent (Modes 9 and 110).
  • a continuous cycling mode of operation requires the operator to adjust his rhythm to that of the machine rather than vice versa as is desirable.
  • adjustment of the lateral position of the head to follow the work so that the platen in its rest position tuated means such as jog buttons, for adjusting the position of the head.
  • Still another object of the present invention is to provide improved control means for traveling head cutting presses which will reduce operator fatigue in the operation of the press in performing cutting operations involving discretionary die placement and which will enhance production by permitting the operator to give his undivided attention to manipulations in the die placement area.
  • a traveling head cutting press is provided with light-responsive control means operative in accordance with the movements of the operator, without necessitating diversion of the operator's attention from work manipulation, for initiating platen movement of translation, either in initiating cutting strokes in response to withdrawal of the operators hands from the danger zone or in causing traverse movement with the head in following the die placement area along the work.
  • the control means is operative to terminate the platen movement automatically.
  • the lightresponsive controls include photoresponsive means and means for illuminating said means effective through an optical path extending adjacent the front of the work support whereby removal of the operator's hands from the work support is operative to initiate a cutting stroke.
  • the lightresponsive controls include illuminating means effective through paths intersecting the work area on each side of the head for response to movements of the operator in moving dies laterally.
  • the movement of the platen between the rest and operative positions is determined by limit switch means.
  • this component of movement be terminated and the downward vertical component of translation, i.e. the cutting stroke, may be tripped manually when the platen arrives at an operative position over the die.
  • This mode is eminently suitable for a press such as said one form in which the platen has horizontal movement only with the head. In such a mode of operation there is no loss of time in transfer of attention and hands to initiate a movement since this occurs during the already initiated horizontal movement.

  • the control includes illuminating means operative via optical paths establishing a light screen" across the front of the support 12 to illuminate light-sensing means, the illuminating means comprising a lamp 150 mounted on one side of the frame It) and paired with a photocell 152 mounted on the other opposite side.
  • control means for initiating translatory movement of the platen in causing traverse movement of the head to follow the work in response to lateral movements of the operator will now be described.
  • a bar 160 carried by the head 22 mounted on a bar 160 carried by the head 22, are four pairs of lamps and photocells 161, 162, 163, 164 each arranged in retroreflective coaxial arrangement wherein the photocell of each pair is arranged for sensing illumination by the lamp through an optical path intersecting the working zone on one or the other side of the head.

  • the optical paths of the four pairs 161, 162, 163, and 164 are designated respectively A, B, C and D.
  • control elements are incorporated in a control circuit, diagrarnmed in FIG. 8a and 8b and to which reference may be had for an understanding for the following description of operation of the preferred form of press.
  • the photocells of the pairs I61, 162, I63 and 164 are shown in lines 1-8, respectively controlling relays A, B, C and D, while the photocells of the light screen shown in lines 9-14 and identified as 152-1, 152-2 and 152-3 respectively control relays H1, H2, and H3 which have their contacts connected in parallel (lines 28-30) and may be considered collectively as H.
  • the platen 30 In operation, accordingly, at rest the platen 30 is in rearward position and actuating a back limit switch, BLS (FIG. 2) by means of a cam 170 (FIG. 2) carried by the platen.
  • BLS back limit switch
  • the head 22 will be between left and right traverse limit switches, Ll-ILS and RHLS (FIG. 1).
  • Ll-ILS left and right traverse limit switches
  • RHLS FIG. 1
  • An adjustable lower limit switch LLS (FIG. 1) is arranged to be actuated when the platen has reached a lower position in which the die has been driven through the workpiece. Such actuation of LLS, (FIG. 8b, lines 35 and 37), energizes relay 111 which latches itself, temporarily preventing reenergization of the relay 1t), and the platen starts to move upward.
  • a switch ULS (FIGS. 1
  • relay 2 is energized and holds itself through a contact in line 17.
  • relay 7 and relay 1TD (line 24) are energized.
  • Relay 7 energizes l Sol, 2 Sol and the Dump Sol in line 34 which operate to accelerate the head to the left. If the operator had kept the relay B energized while he energizes the relay A, the head would not move due to relay 5 being energized. This feature avoids solenoid chatter due to undesirable feed back. Similar protection is provided against the combinations of A and C, B and D, or C and D.
  • relay B When the head catches up with the new position of the operator's wrist, as he is holding the die in the new position, relay B operates to energize the relay 6. This deenergizes relay 2 which deenergizes relay 7 and hence the three solenoids (1, 2 and Dump), decelerating and eventually stopping the head.
  • the pressure relief valve 116 and 118 control respectively the acceleration and the deceleration force and coast distance to achieve smoothness. Suitably, acceleration can be greater than deceleration. Operation on the other side of the head is similar. Note that the use of the dual optical paths A and B results in the head following outward motion but prevents the head moving if the movement is inward toward the center; if relay A is operated and then released before relay B is energized, relay 2 is not energized. Thus the control is operative in response to a predetermined sequence of the optical paths A and B to cause the power means to effect traverse movement of the head.
  • the switch LI-ILS is opened which deenergizes the relay 7, and this in turn, 1 Sol, 2 Sol and Dump Sol, stopping the head.
  • H is deenergized which deenergizes relay 8.
  • the relay 2 is not deenergized because of the relay 1TD contacts in line 15. This timer had started with the traverse. After it times out it deenergizes the relay 2, thus stopping the head as before.
  • the relay 1TD is adjustable and can be preset by the operator according to the distance he wants the head to index in the absence of a normal wristsensing stop signal.
  • the relay 7 has another function during this type of operation. It prevents the down stroke from being started (line 37) until after the traverse deceleration is started.
  • the relay 3 When the operator changes from a leftward to a rightward motion, the relay 3 is energized which deenergizes 3 Sol and also the relay 9 which keeps 3 Sol energized throughout deceleration of the leftward motion.
  • the retroreflective light source and cells are permanently aligned coaxially.
  • the point on the reflective tape where they are directed can easily be adjusted with respect to the head to accommodate the different ways in which different operators might hold the die. By so doing, the head can be made to stop over the die.
  • FIGS. 9, l0, llla and lllb A modification comprising a cutting press having a platen mounted on the head but without capability of forward and rearward movement of the platen relative thereto, is illustrated in FIGS. 9, l0, llla and lllb.

  • CPS center position microswitch
  • LIPS left and a right idle position microswitch
  • RllS right idle position microswitch
  • a solenoid, 7 Sol (FIG. mounted on the head couples the slider to the head to make them move together.
  • the solenoid releases the slider, which is held at that place by the brake solenoid 1 BR (FlG. 10)
  • the head then moves along the slider until the center position switch CPS is reached. There the head stops for the cut. After the cut, the head moves away to the same idle position limit switch on the slider from which it started.
  • operation of 7 Sol recouples the slider and head, the slider brake is released and tracking of the hands is again performed.
  • the time delay ITS makes the head traverse the full index.
  • the head must still move the full covering distance along the slider; there can be no overlapping of motions.
  • the head moves to the frame limit switches LHLS or RHLS, it stops and the operator realizes that he is unable to place the die any further toward that end. He then switches the selector switch to the opposite position and the head immediately moves to the opposite end of the slider, whereupon the operator can now place the die fully to the end of the machine.
