Welder 43(Fig. 3) is divided into two assemblies, is contained in respectively on two flat boards 145 and 146.This flat board is contained on the column 147, and can slide therein, and column is arranged on the left and right both sides of guide 92 and 93.Like this, can make each to guide 92 and 93 and a pair of welder 43 get in touch.

Each welder 43 comprises the parallelepiped-shaped body 151 of a hollow, and transformer 152, air actuator 153, movable electrode 154 and comparative electrode 155 thereof are housed on it.

Movable electrode 154 is fixed on the piston 157 of actuator 153, and actuator passes through cage guiding, and isolates with body 151, and comparative electrode 155 has L shaped polar body, and links to each other on circuit with body 151.Some is contained in transformer 152 in parallel six shape bodies, winding of transformer belt, and its end line can be received on the power supply.Two end lines 159 of the Secondary Winding band of this transformer and 160 are connected on electrode 154 and 155.End line 159 directly links to each other with electrode 155, and is to link to each other by one group of scale copper that curves U-shaped between electrode 154 and the end line 160, like this, can make piston 157 with respect to transformer 152 motions.The shake-up of each movable electrode 154 part (163 places as shown in Figure 5) is the garden cylindricality, and places the position higher than piston 157.This part is to connect outward by piece 164.The shake-up part (165 places as shown in the figure) of each electrode 155 is parallelepiped-shaped, and protruding upward from electrode 155.Piece 164 the insides and electrode 155 the insides at electrode 154 are connected with cooling pipe, are provided with little import and export 166 and 167, are communicated with hydraulic means 60.

Remaining situation is: device 43 163 and 165 parts place steel wire 36 planes below, each dull and stereotyped 145 and 146 can move both vertically with respect to column 147.Actuator 170 drives and moves in the welding assembling 43 and make the planar registration of its 163 and 165 part and steel wire 36.In addition, two end sensors 168 and 169 detect the high and low position of assembling 43 respectively.Situation of change shown in Figure 12 and 13, welder 43 are mounted on two flat boards of fixing 180.Each electrode 171 as shown is equipped with lever arm 173, can be around 172 swing of the sleeve that parallels with piston 157, and the shake-up part 163 of movable electrode 154 and the planar registration of each steel wire 36, and the be placed in below on this plane, the touch part of electrode 171.Lever arm 173 is connected on the air actuator 175 and encircle 174 around vertical monocycle 174 swings.

Actuator 175 can make shake-up part 164 swing, and makes it the planar registration with steel wire 36.At this moment, sensor 168 and 169 detects the high and low position of electrode 171 respectively.

Feeding unit 45(sees Fig. 3 and Fig. 7) include an air actuator 182, have two pistons 183 on it, can be along moving with guide 92 direction parallel with 93.On piston 183, vertical rod 184 is housed, fixing each L shaped horizontal arm 185 on the bar 184, place between the plane of each steel wire 36.Arm 185 has the mid-plane place that longitudinal component 186,186 parts place the vertical marker face that is limited by guide 92 and 93.

On each 186 part, by pivot 187, tooth lever 190 can be swung, the bottom of lever 190 has nipper 191 and back tooth 192.When resting position, lever leans against on the stopping element 188 of 186 parts because the effect of gravity keeps horizontal level, and each tooth 191 and 192 includes corresponding anterior Vertical Meshing limit 193 and rear portion hypotenuse 194.Align in two vertical planes in tooth 191 and 192 engagement limit 193, the interval between them is slightly wider than half (for diameter is the steel wire of 0.6～0.7mm, approximately wide slightly 1mm) of the spacing of steel wire 36 and supporting wire 35.Actuator 182 makes bar 184 motions, thereby makes lever 190 move past the distance of half supporting wire 35 spacing.A pair of end sensor 197 and 196 is accurately measured the terminal extreme position of stroke, and information is sent to control device 57.Can match with supporting wire 35 in control limit 193, promote steel wire 36 together, and make the supporting wires in each steel wire 36 no matter be before framework 30 assemblings, in the process that moves of steel wire 36, still all remains in the same plane in that welding operation is middle.

Particularly on the Support Position, the control limit 193 of tooth 191 or tooth 192 abuts against the back of the supporting wire 35 of steel wire 36, therefore, when piston 183 travels forward, the tooth 191 of lever 190 or 192 front 193 drive steel wire 36 to the motion of the front portion of machine, and the stroke that moves past equals the half pitch of supporting wire 35.

During backhaul, supporting wire lifts tooth lever 190 together with hypotenuse 194, thereby makes limit 193 get back to the back of supporting wire 35 again, so that steel wire 36 is sent to again.Lever 190 is done forward and backward during the shuttling movement, and effect is once on same supporting wire 35 for tooth 191 and 192.Thereby obtain acrossing wire 37, on the framework 30 that has assembled, the spacing of acrossing wire 37 equals half of supporting wire 35 spacings substantially.

Referring to Fig. 1, can see accommodation apparatus 50, have an inverted plane 201, base plate 202 is housed for holding the framework that installs, when machine 40 assembles two highly low frameworks simultaneously, to leave space 203 at least, enable to hold the carriage of second framework.

Control device 57 includes a microprocessor 210, and one group of input/output interface device is housed on it.Input interface receives the data from sensor, and these sensors detect the end-of-travel position whether steel wire and actuator are arranged; Output interface is connected on the relay, perhaps be connected on the solid state switches, control valve 212～219, each actuator 104,113,122,124 127,182,169 and 175 in the pressure air circulation route that is arranged in air assembly 59, and each actuator 153 of welder 43.

Microprocessor can also be controlled power set 226 that are communicated with power supply and a winding that installs 43 transformers 152.Have program on the microprocessor 210, control each motor-driven valve according to the situation of predetermined operation and each sensor.In addition, this microprocessor also is communicated with a series of regulating elements, allows the time interval of welding to change.

Linkage editor can reach 211 and 212 as shown in figure 20 step by step, piles up steel wire 37 and steel wire 36 is positioned at (Fig. 3) on the supporting plane 81 from charging hopper 101.Vertically silk 34 constrains in each guide 92 and 93, is placed on until first group of supporting wire 35 till 193 fronts, control limit of tooth 191.

Machine 40 can be operated two steel wires 37, when two frameworks of assembling, can operate four steel wires, these steel wires are located on the arm 111, and are in vertical position, and bearing 123 is in lateral location respectively, column leaves from arm 111, and at this moment, control device 57 is prepared beginning assembly frame 30.Press initiate key,, promote to be in each lever 190 of machine front, thereby each steel wire 36 to be assembled is moved simultaneously actuator 182 startings.Then, when first group of supporting wire 35 suitably is placed in the same plane, vertical silk 34 weld zones of delivering to separately.

After steel wire 36 is sent to forward, detect by sensor 198, control device 57 is promptly controlled actuator 124, column 126 is taken to the position of contiguous gripping arm 111.Control device 57 is controlled binding clasp 127 again and is clamped steel wire 37, and steel wire is transported to column 126 places.After this situation was sensed, device 57 was handled the another side of actuator 124, moves column and leaves gripping arm 111 together with steel wire.Install 57 acting actuators 121, supporting base 123 is moved to the weld zone.

Control device 57 is handled actuator 124(Figure 15 after sensing the new position of each parts by sensor 131 once more), steel wire 37 is directly taken near vertical silk 34 places.When piston 125 during with respect to the motion of 34 one-tenth 45 directions of electrode axis and steel wire, steel wire 37 and column 126 can not be subjected to the obstruction of these parts and freely-movable.The reposition of steel wire 37 is detected by sensor 133.At this moment, device 57 make dull and stereotyped 145 and 146 together with all welders 43 or make column 174(Figure 13) rise together with single electrode 171, until shake-up part 163 and 165(Fig. 5 of electrode) align with vertical silk 34 and with acrossing wire 37 and vertically silk 34 cross distinguish coaxial placement till.Device 57 also can be controlled actuator 113, makes arm 111 change into horizontal level, grasps another and grasp four steel wires 37 to steel wire 37(or when assembling two frameworks from feed hopper 101).

In subsequent processing, each actuator 153 of device 57 all welders 43 of control, therefore, movable electrode 154 engages steel wire 34 and 37 together with comparative electrode separately.Device 57 provides power (in traversed zone separately) for the winding of transformer 152 and the welding operation of steel wire 34 and 37.When steel wire 34 and 37 still remains on the electrode, install 57 acting actuators 182, make drawback movement to the rear portion of machine, thereby drive lever 190 backward and back tooth 192 is stretched out a little from second group of supporting wire 35.After the reposition of lever 190 was sensed by sensor 197, device 57 unclamped electrode and binding clasp, makes actuator 180 or 175 make reverse motions, and electrode is removed from the path of supporting wire 35.Device 57 holding arms 111 again returns to the upright position.At last, device 57 is removed column 126 and bearing 123 in the weld zone, and like this, machine just returns to original position.

With the part of imaginary point line expression, the position and the binding clasp 127 of expression bearing 123 contiguous weld zones unclamp and are in the position of leaving the weld zone among Fig. 3.The extended position that tooth lever 190 and steel wire 36 are arranged also is to represent with Same Way.Fig. 4 represents the position of actuator 121 and 124 in welding sequence, and steel wire 35 is by 190 alignment of tooth lever are arranged.Position when the position of Fig. 8 indication device 43 when welding sequence, its chain-dotted line represent partly that tooth 192 is accepted steel wire 35.
