When making adjusting handle axle 731 do corresponding rotation when handling adjusting handle 73 clockwise or counterclockwise, drive adjusting screw(rod) bevel gear 741 by adjusting handle shaft bevel gear 7311, thereby make adjusting screw(rod) 74 corresponding rotations, because a pair of suspension bracket fixed head 75 respectively matches with adjusting screw(rod) 74 by its fixed head nut 751, so along with adjusting screw(rod) 74 clockwise or drive a pair of suspension bracket fixed head 75 upper and lower displacements when being rotated counterclockwise, and then by a pair of suspension bracket fixed head 75 drive suspension brackets 76 upstream or downstream, finally drive one group of workpiece signal harvester 8 upstream or downstream by suspension bracket 76, in order to adapt to the adjusting to the thickness direction of workpiece 10.Particularly, when if the thickness of the workpiece 10 of introducing (also can claim height) is large, so suspension bracket 76 do adaptive to top offset, otherwise in like manner, to ensure that workpiece signal harvester 8 is touched workpiece 10, perhaps claims to touch workpiece signal harvester 8 by workpiece 10.

Preferably, set up a upper frame 511 at the top of an aforesaid opposite house font framework 51, and respectively set an adjusting bracket governor motion 9 in the position corresponding to the two ends of the adjusting bracket 71 of workpiece signal collector adjusting device 7, each adjusting bracket governor motion 9 comprises that one adjusts screw rod connecting plate 91 and an adjustment screw rod 92, adjusting screw rod connecting plate 91 fixes with the lower end of adjusting bracket 71, one end of adjusting screw(rod) 92 is connected with upper frame 511, and the other end is connected with adjustment screw rod connecting plate 91.In the time will regulating adjusting bracket 71, the elder generation pine is opened adjusting bracket hold-down screw 713, screw rod 92 is adjusted in turn again, thereby drive adjusting bracket 71 displacements by adjusting screw rod connecting plate 91, regulate complete rear a pair of with lock nut 921() lock, thereby realize the front and back position of workpiece signal harvester 8 is adjusted, in order to adapt with the length of workpiece 10.Particularly, when adjusting bracket 71 during towards the i.e. right displacement under the shown position state of direction displacement of transition roller 3, drive 8 whiles of workpiece signal harvester to the direction displacement of transition roller 3, the distance that the passage of workpiece signal harvester 8 and aforesaid work passage headstock gear 6 is opened and closed between the workpiece baffle plate 631 of arm 63 increases, to adapt to the length of workpiece 10, vice versa.

Above mentioned one group of workpiece signal collection 8 respectively comprises signal picker support 81, signal picker 82 and workpiece contact arm 83, signal picker support 81 is fixed on the aforesaid suspension bracket 76, signal picker 82 is arranged on the signal picker support 81, and shown by circuit 821(Fig. 2) be connected with the electric control box electrical control, the upper end of workpiece contact arm 83 is arranged on the signal picker support 81 by bearing pin 831 pivots, and the lower end of workpiece contact arm 83 constitutes the free end of swing.Swing to feedstock direction in order to limit workpiece contact arm 83, therefore on signal picker support 81 and in the position corresponding to a side of the upper end of workpiece contact arm 83, be fixed with a block 811.

Aforesaid signal picker 82 is travel switch, microswitch, position approach switch, tongue tube or hall sensing element, selects in the present embodiment and uses travel switch.

The applicant describes operation principle of the present utility model in conjunction with Fig. 2, awaiting heat treated workpiece 10 introduces on the transition roller 3, wherein, each workpiece is introduced 311 pairs in passage should one piece of workpiece 10, when for example workpiece introducing passage is six altogether, six pieces of workpiece 10 correspond respectively to each workpiece and introduce passage 311 so, that is to say that each workpiece introducing passage 311 is assigned a workpiece 10, aforesaid one group of work passage headstock gear 6 and workpiece signal harvester 8 respectively have six, under the work of transition roller drive unit, make 3 rotations of one group of transition roller, make workpiece 10 towards left dislocation (take location status shown in Figure 2 as example), when workpiece 10 during by way of workpiece contact arm 83 place, by workpiece 10 striking work contact arms 83, thereby touch signal picker 82 by the swing of workpiece contact arm 83, by signal picker 82 with signal feedback to electric control box, at this moment, one group is that six work passage headstock gears 6 are all located the sealed condition to work passage 211, only have when six workpiece 10 separately workpiece introduce on the passage 311 satisfy towards the condition of the direction displacement of feeding roller 2 after, after also namely six signal pickers 82 all collect workpiece signal, electric control box just sends signal and six acting cylinders 61 is worked simultaneously, by the superincumbent description of applicant, it is open to open and close 63 pairs of work passage of arm 211 by passage.Under the work of feeding roller drive unit 4, make 2 rotations of one group of feeding roller this moment, make workpiece 10 continue to move to left lateral, until enter the heat-treatment furnace that is arranged in left end.Therefore when if six workpiece are introduced any workpiece in the passage 311 and introduced passage 311 and lack workpiece 10, do not make one group of work passage headstock gear 6 be in the state of closed work piece passage 211 owing to satisfy the condition that electric controller responds.Again, because the effect of feeding roller work-piece isolation flange circle 21 and transition roller work-piece isolation flange circle 31, workpiece 10 can not go out existing inclined to one side, thereby guarantees to enter heat-treatment furnace according to the workpiece 10 that needs quantity with the state of running neck and neck.

In sum, the technical scheme that the utility model provides has remedied the drawback in the prior art, has embodied objectively the technique effect described in the superincumbent technique effect of the applicant hurdle, has finished faithfully the invention task
