Definitions

  • Apparatus for assisting an operator in applying bags, closed at the sides and one end, to items such as garments on hangers which are preferably automatically fed to and removed from the apparatus.
  • the bags are formed from material supplied in continuous, tubular form by transversely sealing the material at a desired location and severing it near the seal, thereby closing the top of one bag and leaving an open end of the continuous material for the bottom of the next bag.
  • the bagging material is manually drawn over a garment on a hanger supported at the upper end of a pole. The operation is more efficient than conventional manual garment bagging by making the top of the pole laterally movable to three distinct positions for loading, bagging and discharging the hanger-held garments.
  • the present invention relates to apparatus useful in the application of individual bags, formed from material supplied in the form of a continuous, tubular web, to garments on hangers in a continuous sequence. More particularly, the invention relates to apparatus of this character which is semi-automatic in nature, requiring an operator to draw the open end of the material over the garments, but performing other functions in an automatic manner to increase the efficiency of the bagging operation.
  • 141,882 discloses fully automatic apparatus for applying bags to garments in a continuous sequence. That is, the bagging material is taken from a supply roll and drawn over a garment, sealed and cut to form an individual bag of the proper length, and another garment moved into position for bagging, all in a fully automatic manner.
  • the apparatus is capable of bagging garments at a much faster rate than a single operator using prior, conventional apparatus and techniques, thus providing distinct labor and cost savings in a short period if used to a reasonably full portion of its capacity.
  • Fully automatic bagging apparatus would not be economically feasible, however, in applications having only intermittent need for its capabilities.
  • the present invention seeks to fill the gap between the slower and more burdensome means of garment bagging previously used and the fully automatic apparatus disclosed in the aforementioned copending application.
  • An operator is required for drawing the bagging material over the garment, but the apparatus of the invention provides manyautomatic features which greatly speed up the procedure over prior manual systems.
  • the same bagging material is used with the present invention as with the automatic apparatus, or in other conventional applications, i.e., a clear polyethylene in a continuous double layer, closed at the sides.
  • the apparatus includes a garment support pole movable in response to push button actuation, or the like, under operator control, between three distinct positions of at least the end thereof on which the garment hanger is supported.
  • the hanger In one position (designated the loading" position), the hanger is placed on the pole, preferably by automatic feeding means.
  • the pole In the next position (the bagging position), the pole is disposed with the end supporting the hanger directly under means holding the leading end of the bagging material in an open condition. While the pole is in the bagging position the operator manually draws the leading end of the bagging material over the garment, stopping when it is in the desired position relative to the length of the garment.
  • the operator then actuates an electrical switch, preferably comprising safety interlock means, to cause movement of mechanism which seals and cuts the web of bagging material to form an individual bag for the garment then in the bagging position, also forming a new leading end, held in an open condition, of the tubular web.
  • the pole is then moved to the third, or discharge, position where the bagged garment and hanger are removed, also preferably by automatic ejection means. From the discharge position, the pole is returned to the loading position and the cycle is repeated.
  • a single pole is provided and mounted for movement to each of the three positions in sequence.
  • the pole is pivotally mounted near the lower end and is vertically disposed in the bagging position, being tilted in one direction from the vertical for loading and in the opposite direction for discharge.
  • the mechanism for effecting the sealing and cutting operation, as well as for opening the leading end of the tubular web may be essentially the same as the corresponding mechanism disclosed in the referenced application on the automatic apparatus. In the present invention, however, actuation of such mechanism is not automatic but rather is under the operators control.
  • Safety interlock means are provided to effectively prevent inadvertent actuation of the mechanism.
  • Another object is to provide semi-automatic garment bagging apparatus including means for increasing the number of garments a single operator can bag per unit of time.
  • Still another object is to provide, in semi-automatic garment bagging apparatus having power driven cutting and heat sealing means, novel safety features for preventing operator injury due to inadvertent or careless actuation of the power driven means.

  • Such material is commercially available in the form of a continuous, tubular web, i.e., an elongated double layer, closed at the sides, folded flat and supplied in rolls.
  • the sides may or may not have pleats or gussets, and some rolls intended for strictly manual bagging operations are pre-sealed and perforated at constant intervals along their length, thus requiring no sealing or cutting to form the individual bags.

  • the power supply indicated in the drawing as l 15 volts AC is connected through appropriate fuses 264 to one or more transformers such as that indicated by reference numeral 266 to change the line voltage as required for the components used.
  • the same reference numerals are used to designate portions shown schematically in FIG. 25 as are used to designate the same portions shown physically in other figures.
  • a compressed air supply at approximately 40-60 p.s.i. is required.
  • switch 46 The operator first closes switch 46 and allows a sufficient time for the heat seal elements to warm up. In the meantime, the operator may place a supply of garments on hangers on rod 198 of automatic loader 26, making sure that the hangers are not crossed or tangled. Switch 47 is then manually closed to start vacuum unit 54 and the leading end of the bagging material is opened and one side applied against the opposing faces of the two vacuum bars.
  • Garment pole 30 is assumed for purposes of explanation to be initially in the bagging position, and the operator manually presses the button on panel 50 to close switch 52.
  • This supplies power to the four-way solenoid valve controlling air supply to cylinder 64.
  • the valve is indicated in FIG. 25 by reference numeral 268 and the power supplied through switch 52 actuates the valve to cause inward movement of the cylinder, thereby moving pole 30 to the loading position.
  • switch 84 When pole 30 reaches the loading position the lower end thereof contacts and closes switch 84, as shown in FIG. 4, thereby supplying power to coil 270 of the solenoid which moves arm 216 (FIGS. 17-20) to allow a hanger to be transferred to the garment pole.
  • Closing of switch 84 likewise actuates electronic timer 272 which is adjustable to allow control of the time interval for which garment pole 30 will remain in the loading position.
  • switch 48 is a double pole type having normally closed and normally open contacts.
  • Relay 278 is in an actuated condition with its normally open contacts closed prior to operator actuation of switches 48 and 50.
  • the normally closed contacts of switch 48 provide a holding circuit for relay 278. While the contacts of relay 278 are closed, power is provided to three-way air valve 280 which is interposed in the air line between the pressure supply and the side of fourway valve 276 controlling the air supply for the outward stroke of cylinder 64.
  • the power supplied through relay 278 holds valve 280 open; thus, when the relay is deactuated by movement of switch 48 to the normally open contacts, valve 280 is closed, cutting off the air supply through valve 276 to cylinder 64. Garment pole 30 will then be standing in the vertical (bagging) position without air pressure on the pole pivot cylinder.
  • the new leading end formed when the web is cut will be opened by the vacuum faces and the individual bag formed by the sealing and cutting operation is released.
  • the bag may now be manually pulled down the few remaining inches over the garment with the top of pole 30 and hanger 200 extending through the unsealed area of the material which was between the two sets of heated prongs.
  • switch 49 on panel 44 This switch has two sets of normally open contacts, closure of one set supplying power to actuate solenoid 76 (see also FIG. 5) and of the other set providing actuating current to the coil of relay 278.
  • Actuation of solenoid 76 removes stop 72 from the path of the lower end of pole 30 and actuation of relay 278 again opens valve 280 to provide air pressure through valve 276 for moving cylinder 64 in the outward direction.
  • the provision of relay 278 and valve 280 prevents the more severe shock which would occur in moving pole 30 to the discharge position if constant air pressure were supplied tending to move cylinder 64 to the outward or extended position.
  • pole 30 When pole 30 arrives at the discharge position the lower end actuates switch 82 (see also FIG. 4), closing the contacts thereof and providing power to actuate air valve 284 which controls the supply of air pressure to cylinder 230 (FIGS. 21-24).
  • the cylinder rod will thus move upward, removing the hanger and bagged garment from the end of pole 30, until it reaches the upper limit of its travel.
  • switch 258 When the top of rack 242 contacts switch 258, power is again supplied to valve 268 to move it in the direction providing air pressure to move cylinder 64 in the inward direction. Pole 30 will then be rotated all the way from the discharge to the loading position. Initial movement of pole 30 will release switch 82, thereby deactuating valve 284 and removing air pressure from cylinder 230, allowing pickup member 252 to return to the lower position.
  • Switch 46 and 47 are turned on when use of the apparatus begins and do not thereafter require actuation.
  • Switch 52 is also actuated only once, to effect initial movement of pole 30 to the loading position; thereafter the pole is automatically moved from the discharge back to the loading position.
  • the only repeated operations required of the operator are pulling the bagging material down over the garment in the bagging position, simultaneously actuating switches 48 and 53, and actuating switch 49.
  • the timing of each cycle is under the operators control, thereby allowing the operator to work at a desired pace, but the automation of the handling of the garments and the cutting and sealing of the .bagging material greatly increases the number of garments which a single operator can bag per unit of time.
  • a. support means having an upper portion for receiving and holding a hanger with a garment thereon;
  • guide means establishing the path of the web from a supply location through said initial position as the leading end is drawn downwardly therefrom;
  • e. means selectively operable to effect a transverse seal between the sides of the tubular web and to sever the web adjacent the seal, thereby forming an individual bag and a new leading end of the web.
  • said support means comprises a pole which is substantially vertically disposed at least in said one position of said upper portion.
  • said selectively operable means comprise a pair of relatively movable units between which said web is constrained by said guide means to pass, and which move into engagement with one another with said web therebetween upon actuation of said selectively operable means.
  • said means selectively operable to sever the web comprises a pair of superposed knife edges movable through the plane of the web, to effect severing thereof, and simultaneously movable laterally with respect to one another in sickle blade fashion.
  • a pole having a notched upper end for receiving a garment hanger
  • loader means operable to automatically feed a single hanger from a supply thereof for engagement on said upper end when said pole is in said first position
  • guide means establishing the path of the web from a supply position to a position of the loading end above said second position of said pole, whereby said web may be drawn downwardly over a garment suspendedon a hanger on said upper end when said pole is in said second position;
  • e. ejection means operable to automatically remove a hanger from said one end when said pole is in said third position
