The utility model discloses the intermittent discharging device of a kind of precision tapered roller manufacturing line, this intermittence discharging device layout is arranged in taper roller production on line, and taper roller production on line mainly comprises that frame 1, flexible chain sheet conveying belt 2, intermittent discharge mechanism 3, anti-inertia depart from stock stop, Tong Zhishi limited diameter mechanism, approach switch and control system.
As shown in Figure 1, frame 1 is mainly the profile structure of the T-shaped groove of side band, is mainly used in installing the parts such as flexible chain sheet conveying belt 2, intermittent discharge mechanism 3, anti-inertia disengaging stock stop, Tong Zhishi limited diameter mechanism, approach switch.Frame 1 bottom is equipped with the bearing support of profile structure, and bracing frame consists of base and type groove pillar stiffener.
Flexible chain sheet conveying belt 2 is arranged in frame 1, for support and carry taper roller; .Flexible chain sheet conveying belt 2 is connected successively by the flexible carrier bar 21 of some profiles of tooth and tandem array forms a closed load-transfer device; As shown in Figure 6,7, the upper surface of the flexible carrier bar 21 of profile of tooth has one for holding the V-type groove of taper roller.By motor, drive flexible chain sheet conveying belt 2 to move, and then drive the taper roller on flexible chain sheet conveying belt 2 to move.The main body of flexible chain sheet conveying belt 2 adopts the helix layout (not shown) of extending along short transverse, so that when having enough length to meet process requirements, reduces as much as possible the floor area of on line.And from spiral lower end, draw one section of horizontal segment, and extend to the discharging opening below of last process grinding machine, from spiral upper end, draw one section of horizontal segment, extend to the charging material mouth place of next procedure grinding machine.
Intermittent discharge mechanism 3 has several, and it coordinates with flexible chain sheet conveying belt 2 quantity of taper roller, position control in suitable scope, so that the processing of lower road grinding machine; The concrete quantity of intermittent discharge mechanism 3 is selected according to actual process demand, and it is arranged in frame 1 and is distributed in taper roller mobile route one side, by approach switch and control system, controls.
As shown in Figure 2,3, 4, intermittent discharge mechanism 3 comprises mounting bracket A, blowing cylinder 32, blowing block 33, spacing side plate 34; As shown in Figure 5, mounting bracket A consists of base plate 311 and the air cylinder support 312 that is fixed on base plate 311.Base plate 311 is the metal piece of an end bending, and the end of this base plate 311 is bolted on the sidewall of frame 1, base plate 311 base portions be obliquely installed and with the V-type groove groove parallel sided of flexible chain sheet conveying belt 2.Air cylinder support 312 is a thick stepped plate body in thin bottom, top, and the top of plate body has one, and for the cylinder mounting holes of blowing cylinder 32 is installed, a n shape is arranged in bottom, and this n shape coordinates a rectangle pilot hole of formation with base plate 311.Blowing block 33 is nylon material, can avoid scratch taper roller surface, and it is placed on base plate 311, and through rectangle pilot hole; Blowing cylinder 33 is arranged on air cylinder support 312 by jam nut 35, and its front end is connected with the outer end of blowing block 33 by contiguous block.The inner of blowing block 33 can move to flexible chain sheet conveying belt 2 upper surfaces or away from flexible chain sheet conveying belt 2 upper surfaces under the driving of blowing cylinder 32 and the guiding of mounting bracket A along base plate 311 surfaces.
Intermittent discharge mechanism 3 also comprises a spacing side plate 34, and it is the L shaped plate part that an end bending forms, and flex area, the end length of this spacing side plate 34 is not less than the external diameter of taper roller.It is upper that this spacing side plate 34 is arranged on mounting bracket A, is close to blowing block 33 near a side of flexible chain sheet conveying belt 2 feed ends; Spacing side plate 34 is positioned at the upper surface sidepiece of flexible chain sheet conveying belt 2 and does not affect the movement of taper roller.
The effect of spacing side plate 34 is: during intermittent discharge mechanism 3 blowing, blowing cylinder 32 drives on blowing block 33 and moves away from flexible chain sheet conveying belt, simultaneously, under friction force effect, pull the taper roller 8 of being close to its side, the small end of taper roller 8 is driven movement, but be subject to the restriction of spacing side plate 34, fall back again in the V-shaped groove of flexible chain sheet conveying belt 2, avoid the large small end upset dislocation of taper roller 8 or directly pulled out flexible chain sheet conveying belt 2 and avoid the large small end upset dislocation of taper roller 8 or directly pulled out flexible chain sheet conveying belt.
Those skilled in the art should understand, the spacing side plate 34 is here only exemplary, not circumscribed, for example spacing side plate 34 can be also an arc shape cover cap, this arc shape cover cap covers on flexible chain sheet conveying belt 2, and other can play the shape and structure that stops position-limiting action, repeat no more here.In addition, it is upper that spacing side plate 34 can be arranged on mounting bracket A, also can be directly installed in frame 1.
In above-mentioned intermittent discharge mechanism 3 structures, in order better to adapt to process requirements or specification adjustment, below the exemplary adjustable structure that provides part-structure, for example:
Because frame 1 is the profile structure of the T-shaped groove of side band, this T-shaped groove extends along flexible chain sheet conveying belt 2 moving directions, therefore the base plate 311 of mounting bracket A can embed T-shaped groove internal locking and frame 1 is connected and fixed by T-shaped bolt, thereby can adjust very easily whole intermittent discharge mechanism 3 in the position of taper roller mobile route one side.If above-mentioned spacing side plate 34 is arranged in frame 1, also can connect by which, to adjust.
Adjust for convenience the upper and lower spacing of blowing block 33, when base plate 311 is connected with air cylinder support 312, as shown in Figure 4, open kidney slot D313 on base plate 311, tie bolt 314 is connected and fixed with air cylinder support 312 through after kidney slot D313.
For adapting to the taper roller of different size, on spacing side plate 34, be provided with the kidney slot A341 extending along flexible chain sheet conveying belt 2 fabric width directions, spacing side plate 34 is by being connected and fixed through the adjusting bolt A342 of kidney slot A341 and the base plate 311 of mounting bracket A.
principle of work:
Taper roller moves forward under the driving of flexible chain sheet conveying belt, and each intermittent discharge mechanism is according to the cooperation of the sensor of its outfit and control system, and the taper roller on flexible chain sheet conveying belt is controlled on certain quantity and suitable position.As shown in Figure 8,9, 10, blowing block 33 ends move to flexible chain sheet conveying belt 2 upper surfaces, are blocked on the mobile route of taper roller 8, and taper roller 8 is below blocked, and under the effect of flexible chain sheet conveying belt 2, prop up the side of blowing block 33; When control system is controlled intermittent discharge mechanism blowing according to sensor signal, blowing cylinder 32 drives on blowing block 33 and moves away from flexible chain sheet conveying belt, simultaneously, under friction force effect, pull the taper roller 8 of being close to its side, the small end of taper roller 8 is driven movement, but be subject to the restriction of spacing side plate 34, in the V-shaped groove of the flexible chain sheet conveying belt 2 that falls back again, avoid the large small end upset dislocation of taper roller 8 or directly pulled out flexible chain sheet conveying belt 2.
