This surface of 32 has groove, to form a pair of upper and lower parallel installation groove 38; And each is installed groove and forms relative to each other jut 39 thereon with on the downside, forms the installation pin 40 of outstanding from it minor diameter on its bottom surface.Groove 38 is installed is merged into the end that has outstanding up and down jut 41, walk into broken line to allow lead 60.Pawl 13 connects step shape parts 42, draws lead 60 by lead-in wire groove 43, and the arm 47 of yoke 45 is inserted in the hollow parts 44 in the right cylinder 30.This yoke 45 has C shape and its

arm

46 and 47, and this arm 47 is made for the usefulness of the iron core of coil 31.

General terminal strip that be made of thin plate reference number 50 refer tos and that is connected with lead 60 with coil 31, it has a pair of lug plate 51 that is linked together by gusset 58 with the rear end before it.The part of each lug plate 51 is processed to U font passage 52, and lead 60 just is inserted into wherein, and at the center section of U font passage 52, a pair of relative and two sides joint-cutting 54 formed weld tabs 53 bridged appearances 52.The wire clamp 55 that each lug plate 51 also has a pair of opposing vertical to erect, and mounting hole 56 is arranged.In paired lug plate 51, be used for the top of connecting coil 31 and the coil coupling part 57 of terminal, stretch out in separated direction, and along being cut by the imaginary line shown in 59.

Below, with the installation method of explanation as the electromagnetic counter of above structure.At first, coiling 31 on the right cylinder 30 of coil former 27.Then, for terminal strip 50 being installed on the flange 29 of coil former 27, lug plate 51 inserts in the installation groove 38 of coil former 27 in the direction of arrow A, mounting hole 56 in lug plate 51 is installed in the installation pin 40 that is used to locate, so that temporarily terminal strip 50 is remained on the flange 29 of coil former 27, and pin should be installed, so that stiff end daughter board 50 finally by hot riveting.After this, as shown in Figure 6, a gusset 58 that will be connected to each other lug plate 51 along line of cut 59 cuts.Owing in advance paired lug plate is linked together, and after the installation of terminal strip, cut with this mode, therefore can prevent that the coil coupling part 57 of pointing to different directions is installed in wrong direction, and can eliminate the difficulty assembling of very undersized single lug plate, guarantee to reduce the man-hour of assembling whereby, and can get rid of the mistake in assembling lug plate 51.

Secondly, by the direction of arrow A, lead 60 is injected in the U font passage 52 of lug plate 51.The lead 60 that injects in the U font passage 52 is partly press fit in the joint-cutting 54, and consequently relative weld tabs 53 has cut the protective seam of lead 60, can set up electrically connecting between weld tabs 53 and the inner lead conductor.After this, wire clamp 55 is curved, be drawn out to prevent lead 60, and make lead walk around jut 41 to walk into broken line, so that guide it into lead-in wire groove 43, and this lead-in wire groove 43 is pulled out certainly.Therefore; employing is inserted lug plate 51 in the mounting groove 38 of the coil former that exposes side plate 27 that constitutes frame simply; and in the U font passage 52 with lead 60 insertion lug plates 51; lead 60 can be installed; and energy weld tabs 53 cuts the protective seam of lead 60; between weld tabs and lead 60, set up and electrically connect; thereby; by the method for inserting them by the direction of arrow A; can finish the installation of lug plate 51 and lead 60 and by the method in the U font passage 52 that only lead 60 is inserted lug plates 51; can access electrically connecting between lug plate 51 and the lead 60, therefore, make assembling become easy.The top of coil 31 and terminal around the coil coupling part 57 of lug plate 51 on, and with the method for welding fixed it on thereafter.

At coil former 27, lug plate 51 and lead 60 are placed in together in advance to provide after the coil former parts, and side plate 3 places on the worktable (not shown) in such a way, make the front end points upwards of axle 5 and 6 of frame 2.In the case, the hole 22 of bar 21 is installed on the installation pin 7 of frame 2, makes this bar 21 can swing, spring 25 is added on the projection (not shown) of projection 23 and frame 2 then around this installation pin 27.

Secondly,, will count wheel 15 and pinion wheel 20 and respectively be installed on the axle 5 and 6, not cause the skew of numeral by known mode in the present technique.In this step, it is a lowest order digit number of words wheel to there is no need to check number wheel 15, and can be installed on the axle 5 and 6 counting wheel and pinion wheel continuously, and it is that the lowest order digit number of words is taken turns and do not check the number wheel.Because the number wheel of same form can be counted the number of words as lowest order digit number of words wheel 15a and high bit and be taken turns 15b, and can not occur causing the erection sequence that makes the number wheel of incorrect assembling to take place mistaken, therefore, this makes to reduce the man-hour of assembling and prevent becomes possibility owing to the failure operation that wrong assembling is produced.

Then, above-mentioned coil former parts are fixed to number wheel 15 are housed, on the frame 2 of pinion wheel 20 and bar 21.More particularly, in the hole 34 in the front loaded coil former 27 of axle 5 and 6, and by making pawl 11 connect projection 35, make pawl 12 connect groove 36, with make pawl 13 be connected the method for step shape part 42, coil former 27 and frame 2 can be combined, and flange 29 can play another side plate of frame 2.After this, the arm 46 of

yoke

45 and 47 is inserted in the otch 37 and hollow parts 44 of coil former 27 respectively, so that its front end can be encased in the hole 8 on the frame, finishes assembling whereby.

Because the lateral plate member of frame 2 is divided into two, first side plate 3, another is that a flange 29 by coil former 27 constitutes in a manner described, number wheel 15, pinion wheel 20 and bar 21 can be fixed on the frame 2 through its openings, have alleviated the difficulty of assembling.In addition, owing to construct a flange 29 of coil former 27 to such an extent that resemble another side plate, can be exposed, therefore can be made the installation facility of terminal strip 50 at the mounting groove 38 of the terminal strip 50 that is used for drawing lead.Also have, because axle 5 and 6 and pin 7 is installed is integral with the side plate 3 of frame 2, thereby can number wheel 15 be installed by the direction of arrow A, pinion wheel 20 and bar 21, and also can coil former parts and yoke 45 be installed by the direction identical with arrow A, do not require that between erecting stage frame swings to, thereby improved work efficiency and made and introduced robotization and become easy.

In the electromagnetic counter of as above installing, the outshot of the ratchet 24 of bar 21 partly stretches out in the depression 18 of number wheel 15, and engagement is absorbed in the part of the ratchet-wheel gear 17 in the depression again, therefore, has prevented harmful engagement.Conduction and non-conducting by coil 31 being repeated electric current have realized the work of advancing of several wheels by known mode in the present technique.More particularly, the electromagnet that contains yoke 45 is encouraged or do not encourage, bar 21 is around pin 7 swings are installed, the paired ratchet 24 that causes bar 21 is mesh ratchet gear device 17 alternately, make lowest order digit number of words wheel 15a front when it turns around with box lunch, through pinion wheel 20 the number wheel 15b of next numeral is advanced, realize that there is the carry of the sequential advancement of high bit numeral the back.

By its number wheel 15 are the so-called horizontal type electromagnetic counters of yoke 45 that are parallel to coil former 31 and need the arm 47 of an iron core effect that plays coil former 31, present embodiment has been described, but the invention is not restricted to this, and be used for so-called vertical type electromagnetic counter with may be obvious that, there, iron core stands on the bottom of frame, and the part of frame and armature formation magnetic circuit.

As mentioned above, according to the present invention, the side that lowest order digit number of words wheel is equipped with ratchet-wheel gear is had groove, has formed depression, and transmission gear is housed, high bit is counted the number of words, and wheel construction becomes and lowest order digit number of words wheel has the number of same form to take turns, and the part of the pawl of bar is absorbed in the depression of lowest order digit number of words wheel, and the type number with used number wheel reduces to a kind of thus, prevents the mistake assembling of number wheel with activation, stop harmful operation, and can reduce the time that is used for assembly work.Also have, can reduce the quantity of the metal die of number wheel, thereby reduced the expense of metal die.
