Definitions

  • the well known garment-pressing machine comprises a frame, a stationary buck on the frame, and a movable pressing head pivotally mounted on the frame for movement relative to the buck from an opened position removed from the buck into a pressure-applying position in high pressure engagement with the buck.
  • Various controls have been suggested for such standard pressing machines, which are used primarily by clothing manufacturers, dry cleaners and laundries, to enable the autopressing head relative to the stationary buck for the purpose of reducing operator fatigue, achieving uniformity in pressing from garment to garment and like objectives.
  • a pressing machine which comprises a frame, a stationary buck mounted on the frame and a movable pressing head mounted on the frame for movement into multiple discrete positions relative to the buck including an opened position removed from the buck, a standoff position in spaced confronting relation to the buck, a contact position in contact or zero-pressure engagement with the buck, and a pressure-applying position in high-pressure engagement with the buck.
  • Actuating mechanisms are provided for selectively moving the head relative to the buck which actuating mechanisms include first means operatively connected to the head for moving the head between the open and standofi positions, second means operatively connected to the head for moving the head between the standoff and contact positions, the third means operatively connected to the head for moving the head between the contact and pressure-applying positions.
  • the three means of the actuating mechanisms each embody a separate piston and cylinder assembly appropriate for pneumatic operation.
  • Control mechanisms are operatively connected to the actuating mechanisms for selectively moving the head in multiple closing and opening sequences including, without limitation, a first closing sequence from the opened position successively into the standoff, contact and pressure-applying positions, a second closing sequence from the opened position directly and successively into the contact and pressure-applying positions, a first openingsequence from the pressure-applying position direct.
  • Pressing machines constructed in accordance with the present invention have a number of practical advantages when used at the manufacturing level where materials and new garments are steamed and/or pressed and at the servicing level where cleaned garments are pressed and to some extent rejuvenated by the selective exposure to steam.
  • the ability to establish the standoff position wherein the movable pressing head is in space confronting relation to the buck at a preset but adjustable dis tance (which may be of the order of one and one-half inches) enables the machine operator to process garments of pile fabrics and lengths of such piece goods.
  • High pile fabrics made to simulate furs and knitted materials having pulled naps must be carefully steamed and pressed to avoid damaging the sub-base of such fabric or garment.
  • top steam may be applied to a garment made of a high-pile synthetic such as to press and condition the pile without applying either heat or moisture to the sub-base.
  • the operator may apply bottom steam through the stationary buck which steam pases upwardly through the sub-base and appropriately treats the nap, with the pressing head in the standoff position serving as a hold down for the garment of fabric.
  • a further advantage in accordance with the present invention resides in ability to move the pressing head from the pressure-applying position to the standoff position, with the subsequent release from the standoff position to the open position which sequence of movements of the pressing head relative to the buck precludes the tendency to lift the fabric or the garment from the stationary buck before being thoroughly dried with the attendant risk of wrinkling the same.
  • Still further advantages reside in the ability to repetitively move the pressing head between the standoff and contact positions to achieve a patting action on the fabric or garment, with or without the application of steam and/or vacuum and to apply pulsating high pressure by repetitively moving the pressing head between the contact and pressure-applying positions.

  • air from the air supply line 164 passes through the air inlet 1540 and into the air outlet 154d to achieve the associated control function, as will be described.
  • the air outlet 154d is ported to the atmosphere through the air exhaust 154e.
  • the bottom steam control 154 is connected via line 174 to an air-operated valve 176 which controls the admission of steam from the storage chamber 16a intothe chamber 16b and thence through the contoured and apertured buck Wall 16c.
  • the valve 176 includes an actuating cylinder 176a having a spring biased piston 176b therein which pivots an actuating lever 176:: which moves a valve 176d to selectively connect the steam inlet 176e to the steam outlet 176 which is in communication with the chamber 16b. Since this type of pneumatically controlled valve is of known construction, further description will be dispensed with in the interest of brevity.
  • the pedally-operated top vacuum control 156 is arranged to connect the branch 16% of the vacuumdrawing line 162 to the line 172 and to the pressing head 24.
  • the pneumatically-controlled valve 170 which is connected to the pedally-operated top vacuum control 156 over line 178 is of known construction and includes a cylinder and piston 170a which displaces a cross head 17% controlling a valve 1700 in the valve body 170d which connects the branch 172b to the line 172.
  • bottom vacuum may be applied to the stationary buck 16 upon operation of the pneumatically-controlled valve 166 by the pedally-operated bottom vacuum control 158.
  • the movable or upper pressing head 24 is held at an angle of approximately 55 above the horizontal (see FIG. 2) by the counterbalancing springs 50, 52.
  • the pressing head 24 may be moved from the open position to the standoff position in spaced confronting relation to the stationary buck 16 by pressing the finger button 840 'of the standoff-position control 84 which is effective to pass compressed air from the supply line 98, through valve 84c, over line 110 and shuttle valve 112 and through line 114 which is effective to actuate the diaphragm-operated valve 102.
  • This connects the supply line 98 to line 104 and through quick release valve 106 over line 108 to the pressure side of the cylinder 28 of the standoff-position actuating mechanism 28, 30.
  • Piston 30 is thereby extended to lower the pressing head 24 to the standoff position illustrated in FIG. 3.
  • Such position may be adjusted within a range by means of turning the threaded cylinder head 28a on the off-pressure side of cylinder 28. Further changes in the spacing of the pressing head 24 from the stationary buck 16 in the standoff position may be obtained by exchanging the stroke-limiting spacers contained within the cylinder 28.
  • the machine operator may apply steam to the garmet, either from the pressing head 24 by manipulating control 152 or from the stationary buck 16 by manipulating the pedal control 154.
  • vacuum may be 10 applied to either the pressing head 24 or the buck 16 in the standoff position.
  • the provision of the standoff position is particularly advantageous for the processing of high pile fabrics and of natural or man-made furs.
  • the pressing head 24 may be moved from the standoff position into the contact position by depressing either of the manual contact-position controls 86, 88 or the pedallyoperated contact-position control 96.
  • the rightcontact position control 86 is depressed, pressure from supply line 98 is introduced over line 116, shuttle valve 118, line 120, shuttle valve '122 and line 124 to the pressure side of the cylinder 32 of the contact-position actuating mechanism 32, 34 which moves the pressing head 24 into light contact or zero-pressure engagement with the stationary buck 16.
  • the degree of contact pressure obtained in the contact or zero-pressure position can be controlled by adjusting the amount of air admitted into the cylinder 32 or by adjusting the internal piston-biasing spring in such cylinder.
  • the pressing head 24 may be moved directly from the open position illustrated in FIG. 2 to the contact or zeropressure position by operating the controls 86, 88, 96 in the first instance, without necessity of the preliminary operation of the pressing head 24 under control of the standoffposition control 84.
  • the operator may step on the pedal 96a of the direct-contact-position control 96 which will admit air from supply line 98 over line and shuttle valve 122 to the line 124.
  • the pressure in line 124 is effective via branch 124a, shuttle valve 112 and line 114 to actuate the diaphragm-operated valve 102 which completes a connection between the supply line 98 and the line 104 which is connected to the pressure side of the cylinder 28.
  • the pressure-position control 94 is conditioned for operation since pressure will be applied to line 132 and to the air inlet 940 of this control.
  • the master valve 134 is operated to connect the supply line 98 over line 139, quick-release valve and line 142 to the pressure side of the pressureapplying cylinder 36 of the pressure-applying actuating mechanism 36, 38.
  • the pressing head 24 is lowered to a point of high pressure contact with the stationary buck or lower pressing head at a pressure which may vary anywhere from 3000 pounds to 8000 pounds, depending upon the size of the pressure-supply cylinder 36 and its piston.
  • the master valve 134 is locked in its operated position. Thus, it is possible for the operator to leave the pressing machine 10, with the pressing head 24 remaining in the pressure-applying position. -If on the other hand, feed back valve 138 is closed, the master valve 134 will remain in the operated position for so long as the operator actuates the pressure-position control 94.
  • the pressing head 44 may be moved from the locked pressure-applying position to the open position by momentarily depressing either the right pressure-release control 90 or the left pressure-release control 92.
  • the exhaust outlet 134g of the master valve 134 is ported to atmosphere over lines 146, 148 through valve 90c, air exhaust 902 and muffler 90 This in turn reduces the pressure in line 139 which causes the quick-release valve 140 to quick- 1 1' 1y reverse itself and exhaust air from the pressure-applying cylinder 36 through line 142, quick-release valve 140 and mufi'ler 140e, thereby causing the pressing head 24 to open from the locked pressure-applying position to the fully opened position.
  • a further opening sequence which may be readily attained is movement of the pressing head 24 from the pres sure-applying position to the contact or zero-pressure position. This is attained by depressing either the right or left pressure-release controls 90, 92 and simultaneously depressing either the right or left contact-position controls 86, 88. Depressing either of the controls 90, 92 exhausts the locked pressure-applying cylinder 36, as previously described, while depressing either of the contact-position controls 86, 88 is effective to simultaneously admit air to the cylinders 28, 32 such that the pressing head 24 will move from the open position to the contact position.
  • a still further sequence of opening which may be attained is movement of the pressing head 24 from the lock pressure-applying position to the standoff position. This is achieved by simultaneously actuating either of the pressure-release controls 90, 92 and the standoff-position control 8-4. Operation of either of the pressure-release controls is effective to port the pressure-applying cylinder 36 to atmosphere, while operation of the standoff-position control is effective to operate the stand-otf-position cylinder 28. This causes the pressing head to move from the locked high pressure position to the stand-off position, with the release of the pressing head being timed by the adjustment of the needle 1'26e in the needle valve 126.
  • the reason for the timed release of the pressing head 24 from the contact position to the standoff position is to prevent disarrangement of lightweight garments by the sudden separation of the pressing head 24 from the stationary buck 16.
  • the operator may, after the pressing head is moved into the standoif position, restore the pressing head to the open position by releasing the finger piece 84a of the standoff-position control which is effective to exhaust air from the standofiposition cylinder 28, .as previously described, thereby allowing the counterbalancing springs to rapidly return the pressing head to the open position.
  • Adjustment of the needle valve 146 enables the machine operator to control the delayed release in accordance with the particular type of garment to be pressed with the present machine.
  • the pressing machine will move to the open position rather than go into the pressure-applying position.
  • top vacuum may be applied to the head 24 which will draw the residual steam from the for without causing the fur to mat down, as it would if bottom vacuum were applied or contact pressure were employed to remove such steam.
