With reference to Figure 11 and Figure 12, each draw ring assembling device 192 comprises the center sill 196 that fixedly installs on the pedestal 198, and wherein pedestal 198 activities are contained on the closed slide 200 so that draw ring assembling device 192 moves back and forth with respect to die arrangement 150.A pair of receiver arm 204 links to each other with common axis 206, and common axis 206 utilizes axle journal to be contained in the center sill 196 by crank arm 208.One end of crank arm 208 fixedly installs on the axle 206, and the other end pivot of crank arm 208 installs on the receiver arm 204.

Spur gear 210 installs on the axle 206 and is used to replace crank arm 208 that an end of a receiver arm 204 is connected to axle 206.Spur gear 210 and travelling gear 212 engagements that install on the driving shaft 214, and driving shaft 214 is contained in the end of center sill 196 by axle journal.

Therefore, the rotation of driving shaft 214 makes travelling gear 212 rotations of all draw ring assembling devices 192 simultaneously, and causes that spur gear 210 rotates simultaneously, to realize the reciprocating motion of receiver arm 204.Because receiver arm 204 links to each other by crank arm 208 with center sill 196, thus the rotation of spur gear 210 make receiver arm 204 the upper/lower positions of aiming at die cavity 158 and aim at up ingate 154 on move back and forth effectively between the position.Preferably there is a servomotor 216 (in Figure 11, being represented by dotted lines) to link to each other,, realizes the reciprocating motion of receiver arm 204 between upper/lower positions and last position so that driving shaft 214 back and forth rotates with driving shaft 214.

With particular reference to Figure 13 to Figure 15, generally with reference to Figure 11 and Figure 12, draw ring receiver 220 is contained in the top of receiver arm 204 by unloading power apparatus 260, impacts if draw ring receiver 220 is subjected to enough big power, and this unloads power apparatus then makes draw ring receiver 220 with respect to 204 motions of receiver arm.Each draw ring receiver arm 220 comprises the main body 222 with lower surface 224, is provided with the fluid flow port 240 that links to each other with air pipe line 254 (Figure 16) on lower surface 224.Main body 222 also has and the consistent upper surface 226 of sealing draw ring 32 upper surfaces.Upper surface 226 comprises corresponding to the draw ring part 228 of sealing draw ring 32 draw ring parts 51 with corresponding to the installing stopper part 230 that seals draw ring 32 mounting portions 49.

Draw ring suction inlet 232 is arranged on the draw ring part 228 and is shaped and is contained in the sealing-plug 52 of sealing draw ring 32.Equally, installing stopper suction inlet 234 is arranged on the mounting portion 230 and is shaped and is contained in the installing stopper 50 of sealing draw ring 32.Each suction inlet 232 and installing stopper inlet 234 comprise air duct 236,238 respectively, described air duct is connected to pump orifice 240 by pipeline, therefore fluidised form connects air pipe line 254 and suction inlet 232,234, so that when sealing-plug 52 and installing stopper 50 make sealing draw ring 32 be pressed in draw ring receiver 220 installing stopper 50 and sealing-plug 52 are aspirated picking up.

Unload power apparatus 260 and comprise dull and stereotypedly 261, it is fixedlyed connected with receiver arm 204 by the screw 262 that runs through arm and enter dull and stereotyped 261 sides.Dull and stereotyped 261 comprise pin-guide hole 264 at interval, are provided with air line passageway 266 therebetween, and when air pipe line 254 was installed to pump orifice 240, air pipe line 254 was by this passage.Pin-guide hole 264 comprises frustum of a cone countersunk head part 268 and equal-diameter part 270.

The mount pin 272 that comprises frustum of a cone mount pin head 274 and isometrical axle 276 is set at the size that is contained in the pin-guide hole 264, so that countersunk head part 268 covers of mount pin head 274 and pin-guide hole 264 are got up, and make the end of installation bearing pin 276 run through the equal-diameter part 270 of pin-guide hole 264 and contact draw ring receiver 220.Helical spring 278 is contained in each and extends above axle 276 and between draw ring receiver 220 and dull and stereotyped 261, so that an end of spring is near the lower surface 224 of draw ring receiver, and the other end is near dull and stereotyped 261.Screw 280 passes mount pin 272 and screws in the draw ring receiver 220 again, so that mount pin 272 is fixed on the draw ring receiver 220.

The function of unloading power apparatus 260 is from width of cloth sheet 20 upper punch means of press seals draw rings 32 and pick up by draw ring receiver 220 process of sealing draw ring 32 of punching press and alleviate any power that is applied on the draw ring receiver 220 by contact draw ring drift 108.If between draw ring drift 108 and draw ring receiver 220, come in contact, spring 278 will compress, and draw ring receiver 220 will slide to dull and stereotyped 261, so just make axle 276 in pin-guide hole 264, produce corresponding motion, prevent from other parts of draw ring receiver 220 and draw ring assemble mechanism 190 are caused damage to alleviate power.Because axle 276 slides with respect to dull and stereotyped 261, makes mount pin head 274 leave the countersunk head part 268 of pin-guide hole 264.

Between draw ring receiver 220 and draw ring drift 108 during relative separation, spring 278 bias voltage draw ring receivers 220 leave dull and stereotyped 261 and make mount pin 272 turn back to their previous positions.When they returned, mount pin head 274 was nested in the countersunk head part 268, and its effect is to make mount pin 272 with respect to pin-guide hole 264 centering and aligning.The possibility of clamping stagnation when in addition, countersunk head part 268 reduces axle 276 and slides in equal-diameter part 270.

Figure 16 is the schematic diagram of a kind of possibility method of control and synchronous stamping tool assembly 100 and draw ring assemble mechanism 190 (not shown in Figure 16) and lid production line 10 remainder operations.Two controllers preferably are set: a draw ring assembly controller 250 and a draw ring stamping tool controller 251, can operate the operation of control draw ring assemble mechanism 190 and stamping tool assembly 100 respectively with synchronously.Draw ring assembly controller 250 links to each other by data link (data link) 253 with draw ring stamping tool controller 251, and this data link 253 is Data transmission between controller 250,251 as required, as synchronous or position data.

Draw ring assembly controller 250 can be operatively connected vacuum source 252, and this vacuum source 252 links to each other with the pump orifice 240 of each draw ring receiver 220 of arm 204 ends by air pipe line 254.Air pipe line 254 preferably includes the mounting portion and the flexible pipe part that is connected this mounting portion and vacuum source 252 that links to each other with draw ring receiver 220.Draw ring assembly controller 250 also is connected to air pipe line 254 on the compressed air source 255.

Therefore, draw ring assembly controller 250 can be controlled vacuum or forced air are applied to draw ring receiver 220, so that keep sealing draw ring 32 or blow out any sealing draw ring of staying the die arrangement 150 32 after width of cloth sheet 20 is sheared at them.Draw ring assembly controller 250 also can be operationally connected to pedestal actuator 256, so that the pedestal 198 of draw ring assemble mechanism 190 is with respect to die shoe 152 reciprocating motions of die arrangement 150.Draw ring assembly controller 250 also links to each other with servomotor 216, with the reciprocating motion of realization driving shaft 214, thereby receiver arm 204 is moved back and forth between upper/lower positions and last position.Therefore, the operation of draw ring assembly controller 250 control draw ring assemble mechanisms 190 each parts is with the sealing draw ring 32 of realizing picking up punching press, promote the sealing draw ring 32 that picks up and cover 30 and aim at and will seal draw ring 32 and install to and cover on 30.

Draw ring stamping tool controller 251 can be operatively connected actuator 258, so that stamping tool assembly 100 is with respect to die shoe 152 reciprocating motions of die arrangement 150.Draw ring stamping tool controller 251 also control width of cloth sheet 20 by assembly work station 16 transposition and advance.Therefore, draw ring stamping tool controller 251 control width of cloth sheets 20 advance to the position of transposition, and here stamping tool assembly 100 advances, and from width of cloth sheet 20 upper punch means of press seals draw rings 32, seals draw ring 32 here and can be picked up by draw ring assemble mechanism 190 subsequently.

The pattern of actuator 256,258 can be any suitable actuator, for example, and hydraulic cylinder, pneumatic cylinder, thermo-mechanical drive and motor.And, if carrying out mechanically actuated, draw ring assemble mechanism 190 uses servomotor 216, actuator 256 even controller 250 also within the scope of the invention.If adopt this embodiment, suitable mechanical connection or linkage can be connected to draw ring assemble mechanism 190 on the stamping tool assembly 100, wherein the motion of stamping tool assembly 100 makes draw ring assemble mechanism 190 produce required being synchronized with the movement, and comprises the reciprocating motion of pedestal 198 and arm 204.Vacuum source 252 can be by 251 operations of draw ring stamping tool controller or directly by position sensor, for example limit switch operation.

If with one as required with respect to the operation of various parts in the plastics width of cloth sheet 20 control draw ring assembly work stations 10 and synchronous controller replace a plurality of controllers 250,251 with realize from plastics width of cloth sheet 20 upper punch means of press seals draw rings 32, pick up the draw ring 32 of punching press and the draw ring 32 of punching press install to and cover on 30 also within the scope of the invention.

Referring to figures 16 to Figure 19, the operation at assembly work station 16 is described comprehensively.For convenience of explanation, suppose when stamping tool assembly 100 and bring into operation during near its backstroke, upper and lower receiver arm 204 lays respectively at the upper and lower position, following receiver arm 204 does not transport sealing draw ring 32, is just transporting the sealing draw ring 32 that picks up in the periodic duty formerly and go up receiver arm 204.From this position, draw ring stamping tool controller 251 continues to make stamping tool assembly 100 stable states to move back and forth, and plastics width of cloth sheet 20 is advanced, and transposition next line lid 30 and sealing draw ring 32 make with ingate 154 and aim at.Then, draw ring assembly controller 250 starts pedestal actuator 256, so that draw ring assemble mechanism 190 advances to die arrangement 150.The pace of draw ring assemble mechanism 190 is greater than stamping tool assembly 100 substantially invariable travel speeds, and stamping tool assembly 100 begins from its backstroke position to die arrangement 150 reaches.

With reference to Figure 18, higher speed can make draw ring receiver 220 extend into and pass die cavity 158 when pedestal 198 moved on guide rail 200, exceeded support member 160 and entered the position that is called long travel position.At this moment in periodic duty, draw ring assembly controller 250 is opened vacuum source 252.The purpose of long travel position is to guarantee not seal draw ring 32 to stay in the die cavity 158 from previous periodic duty.If desired, draw ring assembly controller 250 can make a burst of forced air discharge from draw ring suction inlet 232 and installing stopper inlet 234, to blow out any sealing draw ring 32.

Then, draw ring assembly controller 250 makes the reversing of motion of the pedestal 198 of draw ring assemble mechanism 190, so that draw ring receiver 220 is returned to standby position from die cavity 158.At standby position, the pedestal 198 of draw ring assemble mechanism 190 is preferably in and is parked in this position on the guide rail 200, be that draw ring receiver 220 is positioned at the maximum insertion depth that draw ring punch-head assembly 102 can reach, so that closely contact between draw ring receiver 220 and draw ring drift 108, thereby improve the possibility that draw ring receiver 220 picks up sealing draw ring 32 smoothly.If exceed the impulse stroke limit of draw ring drift 108 owing to the position of what reason draw ring receiver 220, unloading power apparatus 260 will make draw ring receiver 220 along with moving with contacting of draw ring drift 108, can not be damaged, still make draw ring receiver 220 can pick up sealing draw ring 32 simultaneously.

With reference to Figure 19, when draw ring receiver 220 was positioned at standby position, controller 251 continued to make stamping tool assembly 100 stable advancing, and arrives its impulse stroke limit up to stamping tool assembly 100.When stamping tool assembly 100 moved to the impulse stroke limit, lid support 104 just is contained in covered in 30, at this moment, aimed at respect to upper inlet hole 154.Equally, draw ring punch-head assembly 102 begins to contact width of cloth sheet 20.Stamping tool assembly 100 continues to its impulse stroke limit and causes draw ring punch-head assembly 102 to extend in the die cavity 158, thus from the width of cloth sheet 20 shearing sealing draw ring 32, surround the zone of the sealing draw ring 32 of positive punching press simultaneously and support by support member 160.

When stamping tool assembly 100 arrives its impulse stroke limit, be under the vacuum condition, draw ring receiver 220 is just being waited for the arrival of the sealing draw ring 32 of punching press from the width of cloth sheet 20.When draw ring drift 108 arrived the impulse stroke limit, sealing draw ring 32 was pulled to draw ring receiver 220 by vacuum.Except picking up and keeping sealing the draw ring 32, when stamping tool assembly 100 arrived its impulse stroke limit, the draw ring receiver 220 that the advancing of the pedestal 198 of draw ring assemble mechanism 190 also causes being positioned at the receiver arm 204 of position compressed current fortune to the sealing draw ring 32 that is just supported the lids 30 of 104 supports by lid.Because draw ring receiver 220 is just keeping sealing draw ring 32, make installing stopper 50 and sealing-plug 52 aim at liquid reservoir 42 and beverage port 41 respectively, tightly suppress with sealing draw ring 32 and to cover 30 and cause installing stopper 50 and sealing-plug 52 to snap into respectively in liquid reservoir 42 and the beverage port 41, install to and cover on 30 thereby will seal draw ring 32, sealing draw ring 32 then is positioned at detent position.

Another advantage of unloading power apparatus 260 is, can control the draw ring assembling pressure by the spring force of selecting spring 278.In other words, transporting sealing draw ring 32 is used to be installed to the draw ring receiver 220 that covers and makes sealing draw ring 32 tightly suppress and cover 30.Be used to make sealing draw ring 32 to tightly suppress cover 30 power to control by the spring force of selection spring 278.

In case stamping tool assembly 100 begins from the impulse stroke limit to the backstroke extreme sport, the pedestal 198 of draw ring assemble mechanism 190 just moves to its backstroke position.When the motion of its backstroke position of pedestal 198 forwards, draw ring assembly controller 250 just starts servomotor 216 runnings, receiver arm 204 is moved on to their opposite location from their current position.In other words, the receiver arm 204 that is positioned at upper/lower positions at present moves on to the position, and the receiver arm 204 that is positioned at the position at present moves on to upper/lower positions.For fear of any potential contact between receiver arm 204 and die arrangement 150 die shoes 152, preferably to return the ingate 154 from the die shoe 152 fully up to draw ring receiver 220, servomotor 216 just begins startup.

When draw ring assembly controller 250 continued to make draw ring assemble mechanism 190 hyperphoric motions (syncopated movement), stamping tool controller 251 preferably continued to make stamping tool assembly 100 stable states to move back and forth.Like this, the draw ring receiver 220 that can finish upper/lower positions on the continuous basis draw ring receiver 220 that picks up sealing draw ring 32 and last position will seal draw ring 32 and snap fit onto and cover on 30.As long as plastics width of cloth sheet 20 is fed on the assembly work station 16, this a series of step will repeat as required continuously.

Will seal draw ring 32 install to cover on 30 after, plastics width of cloth sheet 20 advances to and covers shearing work station 18, lid 30 that has here now assembled and sealing draw ring 32 assemblys are sheared from plastics width of cloth sheet 20 in a well-known manner by drift and punch die, and this is similar to shearing sealing draw ring 32 from plastics width of cloth sheet 20.Therefore, will no longer describe in detail and cover shearing work station 18.Suitable shearing work station 18 is IRAD types 44 of being sold by Ai Erwen Societe Principia Research Development of State of Washington subunit horse, and uses drift and punch die structure to shear the lid 30 that has assembled from width of cloth sheet 20.

Generally speaking, the operation at assembly work station 16 can be thought the assembling process that a kind of machine is handled, here, when plastics width of cloth sheet 20 when 20 transpositions of width of cloth sheet being advanced with respect to each workstation1 2 to 18, sealing draw ring 32 is just sheared one of from a pair of row that comprises delegation's sealing draw ring 32 and adjacent lines lid 30.The sealing draw ring of having sheared 32 is installed into down on the lid 30 in a pair of sealing draw ring 32 and lid 30 row.In other words, the sealing draw ring of having sheared 32 is not to install on the lid 30 of first direct neighbor in capable, but installs on the capable lid of second direct neighbor 30.

Though this special assembling is preferred in proper order, it should not be regarded as limitation of the present invention.Can adopt other order.For example, can be by installing to cover and make stamping tool controller 251 keep stamping tool assemblies 100 will seal in the impulse stroke limit on the lid 30 that draw ring 32 installs to direct neighbor in 30 will seal draw ring 32 in receiver arm 204 position on upper/lower positions moves on to.In this configuration, draw ring assembling device 192 can only need a receiver arm 204.The defective of this assembling is that it is slower than the preferred embodiment operation.

Much can be combined into a work station in the single workstation1 2 to 18 that another possible variation example is a production line 10.For example, Figure 20 illustrates a kind of configuration, and wherein perforate workstation1 4, assembly work station 16 and lid shearing work station 18 are combined into a work station.Because whole three are used a kind of drift and punch die structure to finish perforate, sealing draw ring punching press and lid shearing function usually in these workstation1s 4 to 18, they are combined and will can not have any reluctant technology barrier.

Another variation example that be worth to propose is that draw ring assemble mechanism 190 also can be equipped with one and is used for sealing draw ring 32 is fixed to the supersonic welder that covers on 30.In this configuration, draw ring receiver 220 can also be used to supersonic welder to keep with respect to lid 30 and location sealing draw ring 32.In fact, supersonic welder can install in the part of draw ring receiver 220.Equally, draw ring assemble mechanism 190 can be equipped with a kind of adhesive applicating instrument, bonds to and covers on 30 will seal draw ring 32.

If will seal draw ring 32 installs to along the direction transverse to machine direction and covers on 30 also within the scope of the invention.In this configuration, lid 30 and sealing draw ring 32 will be according to file but not row shown in Figure 2 arrange.Draw ring assembling device 192 will need to rotate about 90 degree, make them at this moment will become in the motion between the upper and lower position and be the motion between the left and right position.Adopt this configuration, be mounted on the lid 30 of adjacent column from a sealing draw ring 32 that is listed as.The defective of comparing this configuration with first embodiment is may assemble less lid 30 to given width of cloth sheet 20 width.Concerning great majority lid production line 10, on the width of width of cloth sheet 20, there is actual restriction.Therefore, from the viewpoint of output, will be more favourable for the lid 30 that given width of cloth sheet 20 width assembling possibility as far as possible is many.

Stroke order and distance are also unrestricted.For example, not problem if sealing draw ring 32 is stuck in the die cavity 158, draw ring receiver 220 does not need to move into long travel position so.But they can directly move on to standby position.

Figure 21 to Figure 31 illustrates the second embodiment draw ring assembly line consistent with the assembly work station of combination shown in Figure 20 16 and final shearing work station 18, and here, draw ring side direction or level install to and cover.Because a large amount of differences between first and second embodiment occur on the assembly work station, therefore will only describe new assembly work station in detail, the explanation that should be appreciated that other work station that is used for first embodiment is applicable to second embodiment.

Figure 21 illustrates a part of plastics width of cloth sheet 320 that is applicable to second embodiment.Lid 330 and sealing draw ring 332 are formed on the plastics width of cloth sheet 320, and arrange with the staggered aligning file that comprises four draw ring row and four lid row.Lid 330 is identical with lid 30, and sealing draw ring 332 is identical with sealing draw ring 32, and just they revolve and turn 90 degrees, and are arranged into file, but not align, and this is the function of level assembling.

As first embodiment, plastics width of cloth sheet 320 preferably is made of suitable plastic, and the example is HIPS.Lid 330 and sealing draw ring 332 are formed on the hot forming workstation1 2, this hot forming workstation1 2 has cover mold type and the sealing draw ring model identical with the cover mold type 62 of first embodiment and sealing draw ring model 64, just in order to constitute the plastics width of cloth sheet 320 shown in Figure 21, model 62,64 is formed row and column.
