As shown in Figure 2, and composition graphs 3, shown in 4, saddle gang stitcher measuring thickness device of the present invention, comprise thickness measuring wheel 1 and be mated the follower 2 of use, follower 2 is installed in rotation on the below of thickness measuring wheel 1, also comprise back up pad 3, swing arm 4 and stop means, stop means can limit the initial oscillation position of swing arm 4, one end of swing arm 4 is installed in rotation in back up pad 3, the oscillation centre place of this end of swing arm 4 has a through hole, swing arm 4 is provided with a servomotor 5 on the side of back up pad 3, the output shaft of servomotor 5 is through through hole, the output shaft passing through hole is fixed with a driving wheel 6, driving wheel 6 and servomotor 5 lay respectively at the both sides of swing arm 4, the side of swing arm 4 back up pad 3 is dorsad fixed with an axle 7, axle 7 and driving wheel 6 are positioned at the homonymy of swing arm 4, axle 7 is rotatably mounted with respectively an engaged wheel 8 and sleeve 9, sleeve 9 is fixed on the side end face of engaged wheel 8, preferred sleeve 9 and the one-body molded making of engaged wheel 8, the outer circumference surface of sleeve 9 is fixed with thickness measuring wheel 1, driving wheel 6 and engaged wheel 8 are set with belt 10, driving wheel 6 drives engaged wheel 8 to rotate by belt 10, the pick-up unit can measuring swing arm 4 swinging distance is provided with between back up pad 3 and swing arm 4, the lower end of swing arm 4 is provided with an elastomeric element, the other end of elastomeric element is fixed in back up pad 3.
As shown in Figure 7, preferably, wheel cause thickness measuring section and the non-thickness measuring section of thickness measuring wheel 1 are formed, and the radius R 1 of thickness measuring section is greater than the dash area that thickness measuring in the radius R 2, Fig. 7 of non-thickness measuring section takes turns 1 wheel rim and namely represents thickness measuring section.When thickness measuring wheel 1 just forwards the position of follower 2 to, books are also just by between thickness measuring wheel 1 and follower 2, and the thickness measuring section only having thickness measuring to take turns 1 so just may leave impression, so thickness measuring section is the smaller the better in theory on books.
Preferably, the mode that one end of swing arm 4 is installed in rotation in back up pad 3 is as follows, as shown in Figure 4, swing arm 4 is fixed on the end face of an inner sleeve 11, inner sleeve 11 is positioned at an outer sleeve 12, and be provided with axle sleeve 13 between inner and outer sleeves 11,12, outer sleeve 12 is fixed in back up pad 3.
As shown in Figure 6, preferably, pick-up unit in the present invention comprises sensor block 14 and photoelectric detector 15, swing arm 4 and the two opposite side surfaces of back up pad 3 are fixed with the first fixed head 16 and the second fixed head 17 respectively, first fixed head 16 is fixed in swing arm 4, and the second fixed head 17 is fixed in back up pad 3, and the lower surface of the first fixed head 16 is provided with sensor block 14, the upper surface of the second fixed head 17 is provided with photoelectric detector 15, and sensor block 14 is positioned at the top of photoelectric detector 15.Photoelectric detector 15 can measure the distance between itself and sensor block 14.Photoelectric detector 15 and sensor block 14 are all device of the prior art, and its concrete structure does not repeat them here.
As shown in Figure 5, preferably, swing arm 4 in the present invention is fixed with the 3rd fixed head 18 away from the back up pad 3 of oscillation centre one end, 3rd fixed head 18 is provided with four rolling 19, swing arm 4 is fixed with a L-type plate 20 away from one end of oscillation centre, L-type plate 20 comprises the 4th fixed head 201 be fixed in swing arm 4 and the 5th fixed head 202 be vertically fixed on the 4th fixed head 201,5th fixed head 202 is between roller 19, and roller 19 is distributed in the 5th fixed head 202 both sides between two and fits with the 5th fixed head 202.Such roller 19 just defines swing arm 4 and can only to swing up and down and can not swing in the horizontal direction, and then makes measurement result more accurate.This embodiment is just illustrated for four rolling 19, and the quantity of roller 19 is not limited thereto, as long as can reach, swing arm 4 is swung up and down.Certainly, the present invention also can not install L-type plate 20 in swing arm 4, but allowing swing arm 4 be located immediately between roller 19 away from oscillation centre one end, roller 19 is distributed in swing arm 4 both sides between two and fits with swing arm 4, so also can reach the object that swing arm 4 works are swung up and down.
Refer again to Fig. 6, preferably, the stop means in the present invention is be threaded in the stop screw 21 on the first fixed head 16, and stop screw 21 runs through the first fixed head 16, and stop screw 21 can contact with the second fixed head 17 or be separated along with the swing of swing arm 4.Because the first fixed head 16 and the second fixed head 17 are separately fixed in swing arm 4 and back up pad 3, so just can regulate the initial oscillation position of swing arm 4 when rotary stopper screw 21 time.
Preferably, the elastomeric element in the present invention is extension spring 22, when swing arm 4 is positioned at initial oscillation position, makes extension spring 22 have certain pretightning force, and namely when books are between thickness measuring wheel 1 and follower 2, swing arm 4 upwards swings the pulling force that will overcome extension spring 22; When books are by between thickness measuring wheel 1 and follower 2, after completing measurement, swing arm 4 gets back to initial oscillation position to lower swing under the pulling force effect of extension spring 22.
In order to make the belt 10 be sleeved on driving wheel 6 and engaged wheel 8 run more steady, the present invention has also installed stretching pulley in back up pad 3, and this stretching pulley and installation method thereof are ordinary skill in the art means, do not repeat them here.
Introduce the course of work of the present invention below:
As shown in Figure 8, the rotating speed of servomotor 5 in adjustment the present invention, makes thickness measuring take turns 1 rotation one circle and only measure books 23, and when books 23 are between thickness measuring wheel 1 and follower 2, the thickness measuring thickness measuring section of taking turns on 1 just forwards the position of follower 2 to.Rotate and regulate stop screw 21 to adjust the initial oscillation position of swing arm 4, because the first fixed head 16 and the second fixed head 17 are separately fixed in swing arm 4 and back up pad 3, and stop screw 21 can contact with the second fixed head 17 or be separated along with the swing of swing arm 4, so when regulating stop screw 21, the initial oscillation position of swing arm 4 can be adjusted.The object of adjustment swing arm 4 initial oscillation position is the thickness measuring wheel 1 that makes to be arranged in swing arm 4 and is arranged on to carry between the follower 2 on books track 24 and reaches a suitable gap, when books 23 advance between thickness measuring wheel 1 and follower 2 along the conveying books track 24 on saddle gang stitcher, swing arm 4 can upwards swing.Photoelectric detector 15 is fixed in back up pad 3 by the second fixed head 17, sensor block 14 is fixed in swing arm 4 by the first fixed head 16, when swing arm 4 upwards swings, photoelectric detector 15 can measure sensor block 14 and the distance between it, and then also just measured the swinging distance of swing arm 4, by the swinging distance measured and standard thickness books, the swinging distance after measuring compares afterwards, rejects the books not meeting standard thickness.After measurement completes, under the pulling force effect of extension spring 22, swing arm 4 is got back to again initial oscillation position and is measured to carry out next time.
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
