Definitions

  • the present invention relates to a glove forming device having glove printing means incorporated therein, and more particularly to a glove forming device having forms on which gloves are formed and having printing means for printing the gloves while on the forms.
  • the printing means comprises a printing mechanism mounted adjacent a glove form of a glove forming device and includes a printing bed formed in the surface of the form, with the printing mechanism operable against the printing bed of the form when a glove is on the form, to print indicia on the portion of the glove that covers the printing bed, without having to remove the glove from the form to accomplish the printing operation.
  • the present invention substantially reduces the time, handling and skill normally necessary for separate forming and printing operations. As a matter of fact, it is possible to accomplish the printing simultaneously with the actual forming operation of the device so that no additional time or handling is necessary.
  • the present invention includes sensing means, which detect the presence or absence of a glove on the form, and means for automatically operating the printing mechanism in response to the sensing means detection so that the printing operation is not only automatic but is automatically controlled to print only when a proper glove is on the form.
  • the glove sensing means are particularly significant when both right-hand and left-hand gloves are being processed on the same forming device. In this case it may be desired to print only particular surfaces of particular types of gloves. This can be accomplished in the present invention by including in the sensing means glove-type sensing means that detect the presence of one type of glove and no-glove sensing means that detect the absence of any glove on the form. By combining the detections of these sensing means and selecting desired conditions the printing mechanism can be automatically controlled to print only a selected type of glove. Printing mechanisms may be provided on both sides of the form, in which case the detections from the sensing means can be selected in a desired combination to operate the printing mechanism for printing of either or both opposite surfaces of either or both types of gloves.
  • the present invention is applicable to various types of glove forming devices.
  • One of the important adaptations of the present invention is in an automatic glove turning and forming machine of the type having sets of turning tubes that carry wrong-side-out gloves to a turning station at which the gloves are turned from the turning tubes onto glove forms on which the gloves are formed and are carried through stations to a station at which the gloves are removed from the forms.
  • Machines of this type are manufactured and sold by Singer-Cobble, Inc., of Riverside Drive, Chattanooga, Tennessee.
  • the printing mechanism or mechanisms of the printing means are mounted at a glove forming station at which the glove from dwells with a glove thereon.
  • the printing mechanism is operable against a printing bed formed in the glove form to print the surface of a glove carried on the form.
  • the printing mechanism is automatically operated in response to sensing means mounted at one of the stations of the turning tubes.
  • the sensing means include no-glove sensing means that detect the absence of any glove on the tubes at the station and glove-type sensing means in the path of a glove thumb tube to detect the absence of a glove of the type that would have its thumb on the tube.
  • the detections obtained from the sensing means are used to control the automatic operation of the printing mechanisms to render the printing mechanisms inoperative when the sensing means detects no glove present and to operate the printing mechanisms when a glove of a particular type is detected by the sensing means.
  • Selectively settable means are provided to control operation of the printing mechanisms to cause the printing mechanisms to print gloves when selected detections are given by the sensing means for printing of either one or both sides of one or both types of gloves.
  • detection retaining means are provided to retain the detection from the sensing means for a period equivalent to the time necessary for a glove to progress from the sensing station to the printing station, at which time the retained detections are applied to the operating means of the printing mechanisms to operate the printing mechanisms in accordance with the previously obtained detections.
  • the detection retaining means may be in the form of a traveling member, such as a rotating disc, that carries displaceable elements.
  • These displaceable elements are displaced by displacing means actuated by the sensing means, and are carried by the traveling member from the displacing means to pick-up means spaced from the displacing means distances equivalent to the distance the displaceable elements move during, the time a glove advances from the sensing station to the printing station.
  • the pick-up means are connected to the operating means for the printing mechanisms to control operation of the printing mechanisms in accordance with the corresponding detained detections of the sensing means selected for particular printing combinations.

(.PARRLSH zdyfvilM JTTORNEV United States Patent Ofiice 3,124,066 Patented Mar. 1%, 1964 s 124 066 Grove rnarvimo hEvicE nAviNe Grove rnm'rmn MEANS rncoaronarnn THERE- The present invention relates to a glove forming device having glove printing means incorporated therein, and more particularly to a glove forming device having forms on which gloves are formed and having printing means for printing the gloves while on the forms.
In the present invention the printing means comprises a printing mechanism mounted adjacent a glove form of a glove forming device and includes a printing bed formed in the surface of the form, with the printing mechanism operable against the printing bed of the form when a glove is on the form, to print indicia on the portion of the glove that covers the printing bed, without having to remove the glove from the form to accomplish the printing operation. Thus, the present invention substantially reduces the time, handling and skill normally necessary for separate forming and printing operations. As a matter of fact, it is possible to accomplish the printing simultaneously with the actual forming operation of the device so that no additional time or handling is necessary.
in addition, the present invention includes sensing means, which detect the presence or absence of a glove on the form, and means for automatically operating the printing mechanism in response to the sensing means detection so that the printing operation is not only automatic but is automatically controlled to print only when a proper glove is on the form. This substantially eliminates the need for any skill or even attention by the operator, further increasing the efficiency and reducing the cost of the printing operation.
The glove sensing means are particularly significant when both right-hand and left-hand gloves are being processed on the same forming device. In this case it may be desired to print only particular surfaces of particular types of gloves. This can be accomplished in the present invention by including in the sensing means glove-type sensing means that detect the presence of one type of glove and no-glove sensing means that detect the absence of any glove on the form. By combining the detections of these sensing means and selecting desired conditions the printing mechanism can be automatically controlled to print only a selected type of glove. Printing mechanisms may be provided on both sides of the form, in which case the detections from the sensing means can be selected in a desired combination to operate the printing mechanism for printing of either or both opposite surfaces of either or both types of gloves.
The present invention is applicable to various types of glove forming devices. One of the important adaptations of the present invention is in an automatic glove turning and forming machine of the type having sets of turning tubes that carry wrong-side-out gloves to a turning station at which the gloves are turned from the turning tubes onto glove forms on which the gloves are formed and are carried through stations to a station at which the gloves are removed from the forms. Machines of this type are manufactured and sold by Singer-Cobble, Inc., of Riverside Drive, Chattanooga, Tennessee. In this adaptation of the present invention the printing mechanism or mechanisms of the printing means are mounted at a glove forming station at which the glove from dwells with a glove thereon. The printing mechanism is operable against a printing bed formed in the glove form to print the surface of a glove carried on the form. The printing mechanism is automatically operated in response to sensing means mounted at one of the stations of the turning tubes. The sensing means include no-glove sensing means that detect the absence of any glove on the tubes at the station and glove-type sensing means in the path of a glove thumb tube to detect the absence of a glove of the type that would have its thumb on the tube. The detections obtained from the sensing means are used to control the automatic operation of the printing mechanisms to render the printing mechanisms inoperative when the sensing means detects no glove present and to operate the printing mechanisms when a glove of a particular type is detected by the sensing means. Selectively settable means are provided to control operation of the printing mechanisms to cause the printing mechanisms to print gloves when selected detections are given by the sensing means for printing of either one or both sides of one or both types of gloves.
As the sensing means are located at a station of the turning tubes and the printing mechanisms are located at a station of the glove forms, detection retaining means are provided to retain the detection from the sensing means for a period equivalent to the time necessary for a glove to progress from the sensing station to the printing station, at which time the retained detections are applied to the operating means of the printing mechanisms to operate the printing mechanisms in accordance with the previously obtained detections. The detection retaining means may be in the form of a traveling member, such as a rotating disc, that carries displaceable elements. These displaceable elements are displaced by displacing means actuated by the sensing means, and are carried by the traveling member from the displacing means to pick-up means spaced from the displacing means distances equivalent to the distance the displaceable elements move during, the time a glove advances from the sensing station to the printing station. The pick-up means are connected to the operating means for the printing mechanisms to control operation of the printing mechanisms in accordance with the corresponding detained detections of the sensing means selected for particular printing combinations.
In this manner gloves on an automatic glove turning and forming machine are printed while the gloves remain on a glove form at one of the normal stations of the machine. Not only does this eliminate the separate glove printing operation, but it also substantially eliminates any attention required of the operator and the need for any skill by the operator in handling the printing operation.

For purposes of illustration, the printing means of the present invention is shown in the drawings and described below as incorporated in a commercial type of glove turning and forming machine, which has not heretofore included any printing means. The particular machine 1llustrated is manufactured and sold by Singer-Cobble, Inc, of Riverside Drive, Chattanooga, Tennessee. This machine includes four sets of turning tubes 22 and four glove forms 24. Each set of turning tubes 22 includes four finger tubes 26 arranged in a row with a right-hand thumb tube 28 on one side of the row and a left-hand thumb tube 30 on the opposite side of the row. These four sets of turning tubes 22 are arranged radially about a hub 32 mounted on the end of a turning tube shaft 34 that is rotatably mounted in bearings 36 in a machine housing 38, and which extends from the machine housing to support rotatably the sets of turning tubes 22 outwardly of the housing 33.
The four glove forms 24 are similarly mounted radially about a hub 40 that is mounted on the end of a glove form shaft 42 that is rotatably mounted in bearings 44 in the machine housing 38 and extends therefrom to support the glove form 24 for rotation on the outside of the machine housing 38. Each glove form 24 has four finger portions 46 aligned in a row and extending from a body portion 48 that has a front face 50 and a back face 52.
The sets of turning tubes 22 and the glove forms 24 rotate in opposite directions, with the tubes rotating in a counterclockwise direction with reference to FIG. 1 and the forms rotating in a clockwise direction with reference to FIG. 1. The tubes 22 and forms 24 are indexed through four stations during each revolution with a predetermined dwell at each station. The sets of tubes 22 advance from an upright glove mounting station 54 to an idle station 56, to a tip punching station 58 at which rods 60 aligned with the tubes 26, 28 and 30 are reciprocated into the ends of the tubes to force the tips of the fingers and thumbs of a glove on the form into the ends of the tubes to facilitate subsequent turning, and to a turning station 62 at which gloves are transferred from the tubes onto an aligned glove form 24 by means (not shown) of the type disclosed in United States Patent No. 2,286,059, for example.
The glove forms 24 are heated by electrical heating coils 25 to heat the gloves and facilitate the forming of the gloves to the shape of the forms. The forms 24 are intermittently advanced in the same manner as the turning tubes 22 through four stations during each revolution. From the turning station 62 the forms 24 advance to an upright forming station 64 at which the glove remains on the heated form. This station may include a set of prongs (not shown) acting on the glove crotches to pull the gloves down onto the form. Pull-down devices of this type are disclosed and claimed in U.S. Patent No. 3,010,- 623, issued November 28, 1961, U.S. Patent No. 3,010, 624, issued November 28, 1961, U.S. Patent No. 3,010, 622, issued November 28, 1961, and pending U.S. patent application Serial No. 40,483, now abandoned, filed July 1, 1960, as a division of above U.S. Patent No. 3,010,623. From the upright forming station 64 the glove forms 24 advance to a horizontal forming station 66, and finally to a stripping station 68 at which the gloves are stripped from the forms by suitable means (not shown), an ex ample of which is disclosed in United States Patent No. 2,286,059, and carried from the machine for subsequent processing and packaging.
The sets of turning tubes 22 and glove forms 24 are in dexed from station to station by means of an electric motor 70 having its drive shaft 72 connected by a pulley 74 to a connecting shaft '76. The ends of the connecting shaft 76 are connected to speed reducers 78, which are connected through Geneva drive motions 80 to the turning tube shaft 34 and the glove form shaft 42 to intermittently drive the shafts and the associated sets of tubes 22 and glove forms 24 through their stations.
The machine described up to this point is the conventional automatic glove turning and forming machine. The incorporation of the printing means of the present invention in this machine will now be described.
The illustrated embodiment of the printing means of the present invention comprises printing beds formed in the front and back faces 50 and 52 of the glove forms 24 (see P16. 7), a pair of printing mechanisms 82, 84 mounted on opposite sides of the glove forms 24 at the forming station 64, which is also the printing station, sensing means 86 at the tip punching station 58 of the turning tubes 22 for detecting the type of glove on the tubes, detection retaining means 88 mounted within the machine housing 38 and capable of receiving detections from the sensing means 86 and retaining the detections during the time a glove advances from the punching or sensing station 58 to the printing station 64, and an electrical control circuit (FIG. 8) for controlling operation of the printing mechanisms 82, 84 in response to the detections retained by the detection retaining means 88.
The printing beds 80 are smooth fiat surfaces formed on the front faces 50 and back faces 52 of the glove forms 24 in the areas against which the printing plates 90 of the printing mechanisms 82, 84 are directed upon operation of the printing mechanisms to print the corresponding surface or surfaces of a glove carried on the form 24.
The printing mechanisms 82, 84 in the embodiment illustrated are standard Model 70AB Markem Printers manufactured and sold by Markem Machine Company of 152 Congress Street, Keene, NH. One printing mechanism 82 is mounted in front of the glove forms 24 on a supporting platform 92 extending from the machine housing 38. The other printing mechanism 84 is mounted in back of the forms 24 and on the machine housing 38. The printing plates 90 extend from the bodies 94 of the printing mechanisms 82, 84 and have ink or other printing material applied thereto by rollers 96 that pick up printing material from a supply pad 98 and transfer the material by rolling over the printing plates 90 when the plates are in a retracted position.
The printing plates 90 are advanced and retracted by air motors 100 that drive rods 102 having the printing plates 90 attached to their outer ends. The air motors 100 are driven by an air system 104 having conduits 106 leading to the air motors 100 from a source of air pressure (not shown) through filter, regulator and lubricator units 108 that condition the compressed air and regulate the pressure for speed control. The air motors 100 are reversible to advance and retract the printing plates 90. The control of the air motors 100 is accomplished by the electrical circuit, which includes limit switches 110 that are actuated by arms 112 extending from the motor rods 102 when the printing plates are fully advanced. These lrmrtswitches 110 are arranged in the electrical control circuit to reverse the air motors 100 and cause the printing plates 90 to return to retracted positions.
' The sensing means 86, located at the punching or sensing station 58, comprise a no-glove sensing switch 114 and a glove-type sensing switch 116. These switches are spring leaf switches that extend from a bracket mounting 118 and have electrical contacts 120 and 122 respectively at their outer ends. These switches 114 and 116 are connected in the electrical control circuit with the machine housing 38 acting as a ground for the circuit so that when the contacts 120, 122 of the switches 114, 1116 contact the tubes 22 the circuit will close and current will flow to the tubes and through the housing 38 to the ground.
The no-glove sensing switch 114 is positioned so that its contact 114 will engage one of the finger tubes 26 of the set of tubes 22 at the sensing station 58. When no glove of any type is on the sets of tubes 22 the no-glove sensing switch 114- will make contact with the finger tube 26 to close the circuit, and thereby detect the absence of any glove on the tubes 22. When a glove of any type is on the sets of tubes 22 the glove material will insulate the contact 120 from the finger tube 26 and the circuit will not be closed, indicating the presence of a glove on the sets of tubes 22.
The glove-type sensing switch 116 is arranged with its contact 122 positioned to contact a right-hand thumb tube 23. As the glove is wrong-side-out when on the tubes 22 the right-hand thumb tube 28 is on the front. When a right-hand glove is carried by the sets of tubes 22 the thumb insulates the glove-type switch contact 122 from the tube 28, preventing the circuit from closing and thereby detecting the presence of a right-hand glove on the tubes. When a left-hand glove or no glove is on the set of tubes 22 there will be no glove thumb on the righthand thumb tube 23 and the glove-type sensing switch contact 122 will contact the tube 28, closing the circuit through the machine housing 38 to the ground, thereby detecting the absence of a left-hand glove from the tubes.
The no-glove sensing switch 114 and the glove-type sensing switch 116 are electrically connected to the detection retaining means 88 that receives the detections from the switches and retains the detections for a period equivalent to the period that a glove would advance from the sensing station 58 through the turning station 62 and to the printing station 64.
The detection retaining means 83 comprises a disc or memory wheel 124 that carries two sets of displaceable elements or plungers 126, 128 and is mounted for rotation on a memory wheel shaft 130 mounted in bearings 132 in the machine housing 38. The shaft 135) is driven through a sprocket 134 by a chain 136 from a sprocket 138 mounted on the glove form shaft 42 for synchronous rotation of the memory wheel 124 with the glove forms 24, with the same intermittent rotation and at the same rate of rotation.
The plungers 126, 128 are slidably positioned in holes 140 of the memory wheel 124 and are arranged in a circle that is concentric with the memory wheel shaft 130. In the embodiment illustrated there are four no-glove plungers 126 and four glove-type plungers 128 arranged in alternation.
A no-glove electric air motor 142 is mounted in the machine housing 38 with an operating rod 144 aligned with a no-glove plunger 126 when the memory Wheel 124 is in a dwell position. The no-glove air motor 142 is connected to the compressed air conduit 106 mentioned above in regard to the printing mechanism air motors 100, is controlled by the no-glove sensing switch 114 so that when contact 120 of the switch 114 contacts the finger tube 26 to close the circuit the air motor 142 will operate to advance the rod 144 against the no-glove plunger and slide the plunger from a rearward position to a forward position. When a glove of any type is on the set of tubes 22 the glove will insulate the contact 120 of the 110-glove sensing switch 114 so that the no-glove air motor 142 will not be energized and will not operate the rod 144. Thus the no-glove plunger 126 will remain in its rear position.
Similarly, a glove-type electric air motor 146 is mounted in the housing 38 with an operating rod 148 aligned with a glove-type plunger 128 when the memory wheel 124 is in a dwell position. The glove-.ype air motor 146 is also connected to the above mentioned compressed air conduit 106, and is controlled by the glove-type sensing switch 116 for actuation of the operating rod 148 to move the glove-type plunger 128 from a rearward to a forward position when no right-hand glove is on the tubes 22 and the contact 122 of the glove-type sensing switch 116 is in contact with the right-hand thumb tube 28. When a right-hand glove is on the set of tubes 22 and the glove thumb insulates the contact 122 of the glove-type sensing switch 116, the glove-type air motor 146 is not actuated and the glove-type plunger 128 remains in its rear position.
A pair of no-glove pickup or memory switches 150, 152 are mounted for contacting the no-glove plungers 126 180 from the no-glove air motor 142. This spacing of 180 is equivalent to the period during which a glove would advance from the sensing station 58 through the turning station 62 to the printing station 64.
The rear switch 156 of the pair of no-glove memory switches is positioned to contact the rear flange 154 of the no-glove plungers 126 when the plungers are in their rear position, which is the position indicating that a glove is on the form at the printing station. This rear no-glove switch is connected in the electrical circuit so that when it contacts the rear flange 154 of the plunger 126 operation of the printing mechanisms 82, 84 will not be interrupted by this switch 150.
The front no-glove memory switch 152 is positioned to contact the front flange 156 of a no-glove plunger 126 when the plunger has been displaced to its forward position by operation of the 110-glove air motor 142 to indi cate the absence of a glove on the form. This switch 152 is normally closed to permit operation of the printing mechanisms 32, $4 and is opened when contacting the flange 156 of the plunger 126 to render the printing mechanisms 82, 84 inoperative when no glove is on the form.
Similarly, a pair of glove-type pickup means or memory switches 158, 160 are positioned 180 from the glovetype air motor 146. The rear switch 158 of this pair of glove-type memory switches is positioned for contact with the rear flange 162 of the glove-type plungers 128 when the plungers are in their rear position corresponding to a detection by the glove-type switch 116 of the presence of a right-hand glove on the tubes. This rear glove-type memory switch 158 is connected in the electrical circuit with selectively settable means to operate or not operate the rear printing mechanism 84 when a right-hand glove is detected.
The front glove-type memory switch 166 is positioned to contact the front flange 164 of the glove-type plungers 128 when the plungers are in their forward position indicating the absence of a right-hand glove on the forms. This front switch 166 is also connected in the electrical circuit with selectively settable means to operate or not operate the front printing mechanism 82 when the absence of a right-hand glove is detected. The absence of a right-hand glove combined with the indication by the front no-glove switch 152, which remains in its normally closed position when a glove is detected on the form, that a glove is on the form, indicates that a left-hand glove is on the form. This indication is supplied the electrical circuit to operate or not operate one or both of the printing mechanisms 82, 84 in accordance with the setting of the selectively settable means.
The plungers 126, 128 are releasably retained in their rear and forward positions by means of spring mounted detents 166 mounted in the memory wheel 124 and extending radially into engagement in either a forward groove 168 or a rear groove 170 in the plungers 126, 128.
After the plungers 126, 128 advance past the memory switches 15!), 152 and 158, 169 the forwardly positioned plungers are returned to their initial rear position for a repetition of the cycle by means of a cam bracket 172 having a cam surface 174 inclined in the direction of movement of the plungers toward the memory wheel 124 so that the cam surface 174 will force the forwardly positioned plungers to their initial rear positions.
The electrical control circuit that includes the selectively settable means and the above described switches, and operates the printing mechanisms 32, 84 in response to selected conditions is illustrated diagrammatically in FIG. 8 of the drawings. This electrical control circuit is comprised of three component circuits, a plunger operating circuit 176, a prove relay and sensing circuit 178, and a printing control circuit 180.
The circuits are powered by a 110 volt, 60 cycle main power line that feeds into a transformer 152 mounted on the inside wall of the machine housing 38. The plunger operating circuit 176 is connected to the primary side of the transformer 182. The prove relay and sensing circuit 178 taps 24 volts from the secondary winding of the transformer 182. The printing control circuit 181) taps 8 volts from the secondary winding of the transformer 182. The machine housing 38 is used as a leg of both the prove relay and sensing circuit 178 and the printing control circuit 189 by one side of the transformer secondary winding being connected to the machine housing 38 and all other control devices of the prove relay and sensing circuit 178 and printing control circuit 131) having one leg also connected to the machine housing 38.
The prove relay and sensing circuit 178 includes a prove relay 184 mounted on the back of the machine housing 38 that closes a switch 186 in a leg 188 of the machine starter coil when the proper voltage is being received from the transformer 182. Also in this leg 1813 of the machine starter coil is a pressure switch 19% mounted on the back of the housing 38 that is connected in the air pressure conduit 1% and remains closed when the proper air pressure is maintained in the conduit 1%. When either the prove relay switch 136 is open due to improper voltage or the pressure switch 1% is open due to improper air pressure the circuit through the leg 133 of the machine starter coil will be open and the machine will not operate.
Also included in the prove relay and sensing circuit 178 independently of the prove relay 134 are the no-glove sensing switch 114 and the glove-type sensing switch 116 arranged in parallel with a corresponding no-glove relay coil 192 and a glove-type relay coil 194 in series with the respective switches. These relay coils 192 and 194 are mounted on the back of the machine housing 38. The lines from these switches are connected to the machine housing 38 so that when either one of the switches 114, 116 is closed current will flow through the closed switch and associated relay coil 192, 194 to the housing 38, which carries the current to the ground. These relay coils 122, 194 operate micro-switches in the plunger operating circuit 176.
The plunger operating circuit 176 includes a no-glove air motor operating coil 1% and a glove-type air motor operating coil 198 arranged in parallel, with the no-glove relay coil 192 controlling a normally open switch 200 in series with the no-glove air motor operating coil 196, and the glove-type relay coil 194 operating a normally closed switch 202 that is in series with the glove-type air motor operating coil 198.
A master switch 264, mounted on the outside of the housing 38, also is located in series with the glove-type air motor operating coil 198 so that the coil will not he energized through the normally closed switch 2%2 when the machine is inactive and the master switch 264 is open.
To control the time during which current will flow through the plunger operating circuit 176 a cam operated plunger circuit limit switch 2% is located in the circuit in advance of the parallel arrangement of the air motor operating coils 196, 193. This limit switch 206 is normally open and is closed for only a limited period of time during each dwell period of the turning tube and glove form. This is accomplished, as seen in FIG. 3, by mounting the plunger limit switch 2196 adjacent an eccentric cam 298 mounted on a rotating shaft 219 that is driven by the speed reducer 78 for the turning tubes 22 at a speed four times the rotational speed of the turning tubes. Thus the plunger limit switch cam 2% makes one revolution during each quarter revolution of the tubes, or, in other words, one revolution for each indexing and dwell period of the tubes and forms. Thus the plunger limit switch cam 2% contacts and closes the plunger limit switch 2% once during each dwell period of the forms to energize the plunger operating circuit 176 for a limited period. When the circuit is energized the switches 2%, 292 operated by the noglove relay coil 192 and the glove-type relay coil 194 respectively will control operation of the no-glove air motor 142 and glove-type air motor 146 respectively.
Thus when no glove is on the turning tubes 22 the noglove sensing switch 114 will make contact with the tubes thereby energizing the no-glove relay coil 192 closing the switch 291 and energizing the no-glove air motor operating coil 196 when the limit switch 236 is closed to operate the no-glove air motor 142, which in turn slides the noglove plunger 126 to its forward position. When a glove of any type is on the tubes the no-glove sensing switch 114 is insulated from the tubes so that the no-glove relay coil 192 is not energized, the switch 2% is not closed, the no-glove air motor operating coil 196 is not energized and the no-glove plunger 126 remains in its rearward position to indicate the presence of a glove on the tubes.
Similarly, when a left-hand glove is on the tubes the glove-type sensing switch 116 will make contact with the right-hand thumb tube 28, closing the circuit to energize the glove-type relay coil 194, which opens the normally closed corresponding switch 202 to de-energize the glovetype air motor operating coil 198 so that the glove-type air motor 146 will not move the glove-type plunger from its rearward position, thus leaving the plunger 128 in a position to indicate the absence of a right-hand glove.
When a right-hand glove is on the tubes 22 the glovetype sensing switch 116 will be insulated from the righthand thumb tube 28 leaving the circuit open without energizing the glove-type relay coil 194 so that the normally closed corresponding switch 262 remains closed, energizing the glove-type air motor operating coil to operate the glove-type air motor 146 and slide the glove-type plunger 128 to its forward position to indicate the presence of a right-hand glove.
The printing control circuit 180 includes the no-glove memory switches 150, 152 and the glove-type memory switches 158, arranged to control operation of front printing mechanism operating coil 214 and rear printing mechanism operating coil 212. This circuit may also include an extend coil 216 and a retract coil 218 for a pull down device of the type disclosed and claimed in the above referred to US. patents.
One 'line of the printing control circuit 181) leads from the transformer 182 through a printing limit switch 220 that is normally open and is closed by a cam 22 mounted on the previously mentioned cam shaft 210 to close the limit switch 229 for a limited duration during each dwell period of the turning tubes and forms. The line then passes through a master switch 224 that is a part of the master switch 264 of the plunger operating circuit 176. This master switch 224 is closed and remains closed during the operation of the machine. The line then includes the front no-glove memory switch 152 that remains close when the no-glove plunger 126 positioned at the switch and corresponding with the condition of the glove form at the printing station 64 is in its rearward position indicating that a glove is on the form.
The line then divides into parallel lines, one of which includes the rear glove-type memory switch 158, which is a two position switch with one position corresponding to the detection of the presence of a right-hand glove on the form and the other position corresponding to the detection of the absence of a right-hand glove on the form. Also associated with the rear glove-type memory switch 158 is a rear toggle switch 230' that is selectively settable to contact either one or both of the rear glove-type memory switch positions to energize the rear printing mechanism 84 when the selected glove is on the form. Beyond the rear toggle switch 230 is a rear printing mechanism toggle switch 232 that is mounted on the machine housing 38 adjacent the rear printing mechanism 84 and is manually controlled to de-energize the printing mechanism, if desired. From the switch 232 the line leads to a rear printing mechanism operating coil 212 that act-uates the air motor 100 of the rear printing mechanism 84.
The other parallel line leading from the front no-glove memory switch 152 is identical to the previously described parallel line, having a two-position front glove-type memory switch 160, a front toggle switch 226 selectively settable to energize the line when a selected glove is on the form, a front printing mechanism toggle switch 228 mounted on the supporting platform 92 of the machine housing 38 adjacent the front printing mechanism 82, and a front printing mechanism operating coil 214.
The printing control circuit 180 includes a rear printing mechanism retract coil 236 connected to the transformer 182 through the previously described limit switch 119 which closes when the printing plate 9% of the rear printing mechanism '84 reaches the end of its printing stroke, to energize the retract coil 236 which causes the printing plate to retract to its original position.
Similarly, a front printing mechanism retract coil 238 is connected to the transformer 182 through a limit switch 110 that closes when the printing plate 90 of the front printing mechanism 82 reaches the end of its printing stroke, to thereby retract the printing plate 90 to its original position.
When the automatic glove turning and forming machine includes a pull down device, such as those disclosed and claimed in the previously mentioned U.S. patents, the printing control circuit 180 can include the line for energizing a pull down air motor. This line can lead from the printing limit switch 220 through the front no-glove memory switch 152, that is closed only when a glove is on the form, to a pull down device energizing coil 216 which is energized to extend the pull down device when the printing limit switch 220 and front no-glove memory switch 152 are closed. The pull down device is retracted by a pull down device retracting coil 218 that is connected to the transformer 182 through the pull down limit switch 244 that is closed by a cam 246 mounted on the above mentioned cam shaft 210 for operation in the same manner as the previously mentioned plunger circuit limit switch 266 and printing limit switch 220. The pull down limit switch cam 246 is timed behind the plunger circuit limit switch cam 20-8 so that the pull down retracting coil 242 is energized after the pull down energizing coil 24 0.
The printing control circuit 180 is completed by connection of all of the coils 212, 214, 216, 21-8, 23 6 and 238, to the machine housing 38, which serves as a ground.
The automatic operat on of the present invention when incorporated in an automatic glove turning and forming machine is apparent from the above description. Thus when the no-iglove sensing switch 114 detects the absence of any glove on the set of tubes 22 at the sensing station 58 it will transmit this detection to the detection retaining means 88, which retains detection for a time equivalent to the time it takes for a glove to advance from the sensing station 58 to the printing station 64, at which time the detection of the absence of any glove will operate through the electrical circuit to render the printing mechanisms 82, '84 inoperative.
When a glove is on the set of tubes 22 at the sensing station 58 the no-glove sensing switch 114 will be insulated by the glove and the glove-type sensing switch 116 will either make contact with the right hand thumb tube 28, if a left hand glove is on the set of tubes 22, or will be insulated by the thumb of a right hand glove. This insulation or contact by the glove-type sensing switch 116 is transmitted to the detection retaining means 88, which retains the detection until the glove has reached the printing station =64, at which time the glove-type memory switches 158, 160 will pick up the detection and through the toggle switches 226 and 230 will operate the printing mechanisms 82, 84 to print the gloves on either side as desired. The toggle switches 226 and 230 are mounted It) on the outer side of the machine housing 38 and are selectively settable to control printing in any desired combination of backs and palms of right or left hand gloves, including printing of both surfaces of both types of gloves.
