To allow rapid replacement of the magazines (70, 72), the invention proposes a fixing of the magazines by folding axle (70, 72) such that the end of the supply rails (69, 71) can be placed at variable distance relative to the corresponding tool (5 or 7).

Description

 00002 Machine for attaching rivets, push buttons or

00003 the like

00004

00005 The invention relates to a machine for attaching

00006 zen of rivets, snaps or the like, with one

00007 as an abutment for the lower tool used for riveting,

00008 a stroke-controlled upper tool and with these tools

00009 gene associated magazines with feed rails for

00010 feeding the parts from the magazine chambers to the

00011 testify. 00012

00013 Although it is possible with known machines, the magazine

00014 ne to replace, for example if designed differently

00015 button parts to be processed. However, this is

00016 associated with increased expenditure of time. This sets the host

00017 economy of a corresponding machine. 00018

The object of the invention is to create a generic

To design 00020 machine in such a way that changing the

00021 magazine can be carried out at short notice. 00022

-D0023 This task is solved with a machine in question

00024 standing type by a foldable axle bracket

00025 magazines such that the end of the feed rails in

00026 bring different distance to the associated tool

Is 00027 bar. 00028

Therefore, a generic machine is specified, the

00030 is characterized by a high level of economy. Sol-

00031 len differently designed button parts by means of the machine

00032 are processed, accordingly adapted maga-

Use 00033 zine. The magazines previously used are closed

Remove 00034. This is done by swiveling the magazine .00035 around its axis bracket, with the end of each 00036 corresponding feed rail in a larger

00037 was brought to the tool. Then that's just that

Bring 00038 appropriate magazine from the axle bracket.

00039 Then a differently designed magazine

Place 00040 on the axle bracket and that of the magazine

00041 outgoing feed rail in correct outgoing

00042 swivel towards the tool. Even if several

00043 magazines have to be replaced, there are minimized

00044 set-up times. 00045

An advantageous further development can be seen in the fact that

00047 the axle bracket is designed as a thru axle bracket

00048 with parallel to the vertical through the tools

00049 kaiebene lying plug direction. The replacement of the

00050 magazine therefore first requires the magazine to be pivoted

00051 interest around the thru axle. At the same time, this is moving away

00052 end of the feed rail from the tool and arrives

00053 thereby in a release position to this. Subsequently

00054 is only the magazine from the thru axle

Deduct 00055. The assignment of a new magazine happens

00056 in reverse order. 00057

00058 So that the magazines do not inadvertently find their installation position

00059, the thru axles are in the

00060 releasably locked. They are preferably located

00061 thru axles on the magazine while the plug-in cavity

00062 is provided on the machine frame side. After insertion

00063 of the plug into the plug-in cavity is the locking

00064 to bring about. This can be done, for example

00065 happen that one with a machine frame

00066 handle provided locking pin is provided, the spring

00067 loaded into an annular groove of the plug and

00068 thus the axially immovable position of the magazine

00069 machine frame secures. Inserting the magazine

00070 has to take place in the folded position, because then that 00071 end of the feed rail the appropriate tool

00072 can happen without interference. 00073

00074 This simple magazine replacement is optimized

00075 in that a locking of the end of the feed

00076 rail provided in the working position for the tool

Is 00077. Then comes in the final phase of the folding movement

00078 the feed rail in this lock to the tool.

00079 The end position can also be locked

00080 ung be saved. The corresponding element can

00081 can be a locking pin, which can also be

00082 have been equipped and therefore tool-free in one

00083 release position can be brought. 00084

The pivotable assignment of the magazines allows z.

00086 B., by means of a single machine push buttons on loading

Attach 00087 garments. A push button sits down

00088 known to consist of two functional parts and these

00089 arranged holding parts, the latter being the same

00090 are designed. To make this possible, several are in the

00091 machine cycle different in the working position

Moved magazines provided such that the lower or

00093 upper tool supplied different parts

00094 are always used to assemble with a

00095 the counterpart fed from a third magazine.

For example, the counterpart representing the holding part can be

00097 lower tool are fed. The others, the functional

Parts representing parts, then arrive from the

00099 both in the machine cycle different in working position

00100 on moving magazines to the upper tool. 00101

Such a design is optimized in that the

00103 pivoting movement of the two magazines by coupling the

00104 same is synchronized in opposite directions. In detail, 00105 ^' looks so that when one of the feeders 00106 guide rail or magazine the other feed rail

00107 or magazine, in which the channel of the feed

00108 is brought into the muzzle connection

00109 insertion channel for the upper tool. That way

00110 achieved a certain switch function. 00111

00112 It is also advantageous that the feed rail of

00113 one side wall of the magazine goes out, on which

00114 the magazine chamber unloads like a backpack, the

00115 axis bracket runs in the plane of the side wall,

00116 which on the opposite side

00117 shaft carries. The side wall represents the product area

00118 for the button parts. In connection with the circulating

00119 the drum-like magazine chamber are therefore the parts

00120 always oriented oriented of the feed rail

Pass 00121. This arrangement of the axis bracket to the plane

00122 of the side wall also allows magazines in 180 different

00123 used position. Nevertheless, the

00124 side wall representing the product surface always the same position

00125 on to the tool. 00126

00127 It should then be emphasized that the end of the feed

00128 rail associated with a feed slide stored there

00129 is. If this is in alignment with

00130 upper tool, it can by means of a rotary drive

00131 branched feed drive in the direction of the upper

00132 stuff or be pushed in its pliers. 00133

00134 Finally, there is an advantageous feature

00135 in that the feed to the lower tool by means of a

00136 rod takes place, in addition to locking a

00137 foldable support platform is used in the working position.

00138 The rod is the component that the of the

00139 assigned feed rail hurry coming to

00140 ^' Lower tool moves. Since the rod is still at the same time 00141 Locking a foldable support platform in the

00142 serves the working position, it fulfills a double function

00143 saving on components. Exclusively in the

00144 moved back position of the rod, ie during the

00145 riveting process, the support platform as intended

00146 fold down so that the connection process can be

00147 riveting is not affected. 00148

00149 The following is an embodiment of the machine

00343

00344 The machine according to the first embodiment has

00345 a supported vertically by a footplate 1

00346 aligned stand 2. The latter carries in alignment

00347 Alignment of a mounting plate 3- From the narrow side

00348 of the mounting plate 3 is received in a horizontal orientation 00349 outrigger 4, which has a substation at its free end

00350 stuff 5 supports. In alignment with this

00351 a plunger 6 is guided in a vertical orientation,

00352 which is assigned an upper tool 7 at the lower end

00353 is. 00354

00355 At the upper end of the plunger 6, a double

00356 armed power transmission lever 8 with interposition

00357 a handlebar 9. The power transmission lever 8 is supported

00358 can be pivoted about an axis 10 on the mounting plate

00359 the lever 9 opposite, longer dimensioned lever

00360 arm is via a pivot pin 11 with a crank arm

00361 12 coupled. This essentially consists of three

00362 parts together, namely the two separate

00363 th crank arm sections 13, 14, between which one

00364 as a compression spring buffer spring 15 is switched.

00365 The crank arm section 14 is articulated via a pin

00366 fen 16 connected to a crank disc 17. Latter

00367 supports a coaxially arranged drive

00368 disc 18. Between this and the crank disc 17th

00369 there is a cam plate 19 with two axially

00370 cam cams 20 lying one behind the other,

00371 21. These are arranged approximately diametrically to one another and

00372 extend on rotationally offset

00373 levels. 00374

00375 A toothed belt 22 is placed around the drive pulley 18,

00376 which to a motor drive pulley 23 one on the

00377 mounting plate 3 leads electric motor 24 leads. 00378

00379 The cam disc cam 21 works together with one

00380 switch 25 in the raised position of the plunger 6 or upper

00381 tool 7. With the other cam control cam 20,

00382 which over the cam control cam 21 over 00383 extends a larger angle of rotation, an over-

00384 bridge switch 26 together. 00385

^■ 00386 The upper tool 7 contains one at the lower end of the

00387 ram 6 specified upper stamp 27 and a rivet

00388 tool 28. This has a ram 6

00389 gripped jaw holder 29. In the same

00390 arranged brake elements 30 cause a frictional connection to

00391 plunger 6, see Fig. 7. The jaw holder 29 is

00392 with an insertion slot 31 open at the bottom for

00393 the bearing arms 32 of two jaws 33 equipped.

00394 The insertion slot 31 cross two at the same height

00395 lying holes 34 which with holes 35 of the bearing

00396 me 32 aligned. The holes 34, 35 are pivoted

00397 axles 36 penetrated to achieve a swiveling

00398 speed of the jaws 33 relative to the jaw holder

00399 29. A tension spring 37 engaging the jaws 33

00400 loads the jaws 33 into a gripping position

00401 each other. The jaws 33 are used to hold a

00402 push button part 38. 00403

00404 The two swivel axes 36 sit on a bridge 39 connecting them. This bridge is the carrier of one of their front sides.

00406 te outstanding pull-out handle 40. So the bridge

00407 39 with the swivel axes cannot be moved unintentionally

00408, it is covered by a locking screw 41

00409 gen. Their head has a flat 41 '. Will the

00410 screw starting from FIG. 29 in the position according to

00411 Fig. 31 rotated, i.e. by 180 ^° , the bridge becomes 39

00412 released. You can then use the pull-out handle

00413 be 40 including the swivel axes are pulled out,

00414 see in particular Fig. 32. The jaws 33 are

00415 can then be removed. If necessary, a manufacturer

00416 take off the upper punch 27. This disassembly

00417 can be done without tools, apart from twisting 00418 the locking screw 41. Other to be processed

00419 Pliers jaws adapted to the push button parts can then be used for

00420 use. The assembly of the same happens in

00421 reverse order. 00422

00423 The lower tool 5 includes one in a sleeve 42

00424 of the boom 4 bound lower stamp 43. A printing

00425 spring 44 surrounds the central area of the lower punch

00426 43 and applies a sleeve 45 in the upward direction.

00427 A support platform 46 is supported with its front end

00428 on a recess 45 'of the sleeve 45. This will

00429 the support platform 46 in the direction of a horizontal,

00430 position limited position. The platform

00431 46 can be folded down about a pivot axis 47, which is a

00432 bore 48 of the platform 46 and a boom side

00433 passes through hole 49. Locked in their inserted position

00434 tet the pivot axis 47 of the platform 46. To this

00435 purpose is a spring-loaded locking pin 50 on the boom side

00436 provided that in an annular groove 51 of the pivot axis 47

00437 engages. This pivot axis 47 is also with a

00438 pull-out handle 52 equipped. As long as the swivel

00439 axis 47 is in its inserted position,

00440 the support platform 46 secures the downward insertion

00441 Connection of the lower tool 5. Dismantling the

00442 lower tool 5 requires pulling out the swivel

00443 axis 47. As a result, the support platform 46 is free and can

00444 are lifted off, whereupon the parts of the substation

00445 stuff, as FIG. 34a illustrates, without tools

00446 removed and possibly replaced by others.

00447 Assembly takes place in the reverse order. 00448

00449 The aforementioned support platform 46 contains a longitudinal

00450 directional feed channel 53 for the corresponding

00451 corresponding push button parts 54. The feed channel 53 is

00452 passable by a rod 55. In the top dead center 00453 position of the plunger 6, the rod 55 has completely

Pass through feed channel 53 of the support platform 46. He

00455 extends with its front end in front of the lower

00456 stamp 43 and therefore has a push button part beforehand

00457 54 in the correct position for the lower stamp 43

00458 brought. At the same time, the rod 55 prevents

00459 pen of the support platform 46 about the pivot axis 47.

00460 the rod 55 locks the working position of the support

00461 stage 46 and is also the loading slide

00462 of the lower tool 5. 00463

00464 The drive of the rod 55 is derived from the rotary drive.

00465 tet. For this purpose, the rod 55 sits on a back and forth

00466 movable carriage 56. Serve to guide it

00467 the boom 4 protruding, parallel to it

00468 rails 57. On a backdrop 58 of the carriage 56

00469 a driver articulated on the mounting plate 3 engages

00470 lever 59 on. The pivot point of the same is 60

00471 draws. From the middle section of the driver lever 59

00472 a boom 61 pointing in the direction of the plunger 6

00473. At the end, this is equipped with a roller 62.

00474 This occurs against the underside of a driver 63 of the

00475 plunger 6 and is in this position by one

00476 driver lever 59 stressing tension spring 64 held. at

00477 is its upper dead center position tappet 6

00478 therefore the driver lever 59 pivoted so that the

00479 carriage 56 the rod 55 locked the support platform 46

00480 and extends to the lower stamp 43. 00481

00482 The carriage 56 has a monitoring

00483 assigned switch 65. 00484

00485 Through the carriage 56 are also the push button parts

00486 38 in the rivet holding tool 28 or its pliers jaws

00487 33 moves. For this purpose, parallel to rod 55 00488 slide rod 66 which can be displaced in the axial direction.

00489 the latter is aligned with a feed slide 67, which

00490 is guided in a bush 68 of the end of a feed rail 69 00491. A compression spring, not shown, is

00492 strives to feed slide 67 against the direction

00493 to shift the jaws 33. By means of the feed

00494 slide 67, the corresponding, from the feed

00495 rail 69 coming push button parts 38 in the

00496 rivet holding tool 28 inserted. The feed rail

00497 69 in turn is based on a magazine 70, which in the

00498 ways of the thru-axle bracket of the mounting plate 3

00499 is assigned. 00500

00501 The lower tool 5 is also loaded

00502 by a feed rail 71 which is

00503 zin 72 and the lower end with the feeder

00504 channel 53 of the support platform 46 is aligned. This maga-

00505 zin 72 is the mounting plate 3 by way of the thru-axle

00506 assigned to bracket. 00507

00508 goes upward from the jaw holder 29

00509 a lifting rod 73, the upper end of a through

00510 tread bore 76 one connected to the upper end of the plunger

00511 which block 75 passes through. Beyond block 75

00512 carries the lifting rod 73 by means of a screw 77

00513 firmly connected holding arm 78 for one part

00514 79 of a switch 80. The other part 81 is against it

00515 set at block 75. 00516

00517 The switch 80 and the bypass switch 26 are

00518 connected in parallel to each other. In top dead center

00519 development of the plunger 6 when properly introduced

00520 push button parts 38, 54 is the bypass switch

00521 26 open while the other two switches 80, 65

00522 have closed. 00523 With regard to the push-button part 38 which

00524 Genbacken 33 is held, it is the function

00525 on part of a push button, while the other push

00526 button part 54, supported by the lower stamp, the holding

00527 is part. 00528

00529 The machine works as follows:

00530 According to FIGS. 1-10, the starting position is in

00531 which of the plunger 6 is in its upper dead center position

00532 lung. Furthermore, the carriage 56 is attached to it

00533 advanced rod 55 and push rod 66,

00534 whereby the push-button parts 38, 54 to the rivet holder

00535 28 or lower tool 5 have been passed. The

00536 Monitoring switch 65 and switch 80 are closed

00537 sen while the bypass switch 26 is open.

00538 If the command is now given using the foot switch 82,

00539 after inserting one with the

00540 number 83 designated garment between upper

00541 and lower tool, sets the rotary motion of the drive

00542 a. Accompanying the crank disc 17 and

00543 crank arm 12 of the power transmission lever 8 pivoted

00544 with accompanying downward displacement of the plunger 6

00545 with upper tool 7 and rivet holding tool 28. The latter

00546 experiences its synchronous shift to the plunger 6

00547 the braking elements 30. In FIGS.

00548 position illustrated. In this there is

00549 rivet holding tool 28 so far that between

00550 this and the support platform 46 a safety distance

00551 of a is present. The measure of the safety distance

00552 can be approx. 4 - 5 mm. Along with this

00553 The carriage 56 has also been displaced over the driver.

00554 lever 59 has been moved back to a certain extent. The

00555 switch 80 has not yet opened, so that the

00556 electric motor 24 continues to be driven.

00557 ' 00558 However, as is illustrated in FIGS. 15 and 16, 00559 can occur that above the substation

00560 stuff 5 is a finger. In the case of the aforementioned

00561 shifting the ram 6 with rivet holding tool 28

00562 then presses the finger with the specified

00563 NEN, not leading to injury friction force.

00564 The part 79 of the switch 80 thus remains standing while

00565 the plunger continues its downward movement

00566 Take part 81 of the switch. The switch 80

00567 thus opens. Because then the bypass switch

00568 26 still occupies the open position, the power supply

00569 to motor 24 interrupted while at a standstill

00570 of the machine, so that the plunger 6 with the upper punch 27

00571 is no longer advanced. 00572

00573 However, if the safety distance a is maintained,

00574 the drive can be continued achieving a

00575 another intermediate position in FIGS. 17-19.

00576 riveting tool 28 has on the garment

00577 83 put on and accompanying the support platform 46 in

00578 folded down. This is possible because of the

00579 on the sled 56 rod 55 the support platform 46

00580 has released. However, the jaws are 33

00581 still closed and hold the pressure

00582 button part 38. Furthermore, the carriage 56 has the monitoring

00583 activated switch 65, which, however, no

00584 flows on the rotary drive. In the further course of the

00585 drive ram 6 hurries opposite the rivet holder

00586 28 before connected to an opening of the switch 80.

00587 Before, however, the bridging of the cam 20

00588 switch 26 was actuated in the sense of a closing,

00589 so that the tappet drive is not interrupted. 00590

00591 Figures 20-24 illustrate bottom dead center

00592 Position of the plunger 6 with the upper stamp 27. The latter has 00593 the pliers jaws 33 spread apart and the connecting

00594 fertilize the upper push button part 38 with the lower

00595 push button part 54 brought about - as shown in FIG.

00596 light, the cam disc cam 20 acts on

00597 the bypass switch 26. 00598

00599 During the upward stroke of the ram 6 in the direction

00600 its top dead center position becomes an intermediate position

00601 according to FIGS. 25-27 reached. About the take-away hebe1 59

00602 the rod 55 seated on the slide 56 comes back in

00603 support position to the platform 46, which due to

00604 the compression spring loading of the lower tool 5 in the

00605 has moved the horizontal position. At the same time, the staff takes off

00606 55 a new lower push button part 54 with, during the

00607 slide-in plunger 66 an upper push-button part 38

00608 pushes. The upward displacement of ram 6 and rivet

00609 holding tool 28 takes place synchronously. About the senior

00610 stamp 27, the jaws 33 are still in

00611 their spread position. In the course of the others

00612 upward movement acts on the jaw holder

00613 29 stop screw 84 a fixed attachment

00614 impact shoulder 85 of a fixed to the mounting plate 3

00615 th bearing bush 86. Accordingly, the rivet holder

00616 stuff 28 stand while the plunger 6 with the upper

00617 stamp 27 moved further up. The is limited

00618 upward displacement by the cam disc cam 21,

00619 which operates the switch 25. It's going on this

00620 way back to the starting position of the machine

00621 leads- 00622

00623 If the rod 55 with the slide 56 during the upward

00624 displacement of the plunger 6 at its forward displacement

00625, for example due to a faulty lower one

00626 push button part 54, the monitoring switch 65

00627 still applied. Furthermore, the rod 55 00628 not supported the support platform 56. The working stroke

00629 could not be initiated because of the

00630 broken power supply to the rotary drive. Switching on

00631 requires the intended advance of the slide

00632 tens 56 with the rod 55 while securing the work position

00633 development of the platform 46. 00634

00635 Figs. 1 and 3 illustrate that the machine with

00636 is equipped with two magazines 70, 72, which are

00637 rer axle bracket of the mounting plate 3 are assigned.

00638 The axle bracket is 87 as a thru axle bracket

00639 designed with parallel through the tools

00640 vertical plane lying plug direction. To this end

00641, each magazine 70, 72 supports a thru axle 88.

00642 This is carried by a Bock 89. On the machine

00643 assigned magazine engages the thru axle 88 in the

00644 cross-sectional slot 90 each a Lagerbok-

00645 kes 91 of the mounting plate 3. 00646

00647 The feed rail 69, 71 starts from one side .00648 wall 92 of the magazine 70 or 72, on which the

00649 magazine chamber 93 unloads like a backpack. Regarding DIE ^"0.0650 ser magazine chamber 93 is it is a revolving

00651 drum, which is rotationally driven in a manner not shown

00652 ben. The thru-axle bracket 87 runs in

00653 the level of the side wall 92, which is opposite to

00654 magazine chamber 93 has a feed chute 94. A

00655 axis 95 of the magazine chamber 93 passes through the filling

00656 shaft 94. It is both possible to use the magazine chamber 93

00657 itself or to drive the axis 95, namely

00658 by means of drive belts, not shown. Therefore

00659 it is possible to drive the belt both inside and

00660 to be provided on the outside of the magazine 70, 72. 00661 00662 Due to the axis bracket of the magazines 70, 72 lies

00663 a pivotable arrangement of the same, so that it

00664 is possible, the end of the feed rails 69 and 71

00665 at different distances from the associated tool 5

00666 or 7 to bring - In the working position to the tool

00667, however, is a lock on the end of the feeder

00668 rails 69, 71 provided for tool 5 and 7 respectively. So is

00669 the lower end 71 'of the feed rail 71 through

00670 a plug 96 provided with a handle

00671 xiert- This can for example be cushioned

00672 be such that it is spring-loaded in the locking direction

00673 is loaded. The lower end provided with the sleeve 68

00674 of the feed rail 69 can pass through in a similar manner

00675 pin holder to be secured, which is not closer

00676 is illustrated. 00677

00678 In order to be able to replace the magazines 70, 72, it is necessary

00679 a release of the locking of the ends of the feed

00680 rails 69 and 71, respectively. Then magazines 70, 72

00681 swiveled around their axle mounts and the thru axles

00682 88 are pulled out of the recesses 90, this

00683 possibly with the release of a corresponding lock

00684 of thru axles. 00685

00686 You can also insert a new magazine

00687 short-term and tool-free. 00688

00689 FIGS. 35-42 illustrate a modified

00690 designed machine, which with three magazines 97, 98, 99

00691 is equipped. These are also in the way of the plug

00692 axis bracket 87 assigned to the mounting plate 3

00693 Magazine 97 - 99 correspond in their structure to the pre-

00694 wrote magazines 70, 72. Of the two outer ones

00695 magazines 97, 99 go feeder rails 100 and 101

00696. These both lead to the upper tool 7. These feed 00697 guide rails 100, 101 are feeders from as functional

00698 parts designed push-button parts from the magazines

00699 97, 99 for rivet holder tool 28. From magazine 98

00700 are 102 push button parts via a feed rail

00701 passed to the lower tool 5. Regarding this pressure

00702 knob parts are for the two function

00703 parts valid holding parts. 00704

00705 The definition of the lower end of the feed rail

00706 102 is also done by locking. 00707

00708 The other feed rails 100, 101 can alternate

00709 in the aligned position to the plunger 66 of the

00710 carriage 56 are brought, so that either from the

00711 one or the other feed rail 100 or 101 the

00712 functional parts are fed to the rivet holding tool 28

00713 den. The lower end of each feed rail 100, 101

00714 is also provided with a bush 68 for this purpose.

00715, in which a feed slide 67 leads.

00716 Furthermore, both ends are shown schematically by a

00717 light coupling element 103 interconnected. There are

00718 therefore two different in the machine cycle in the

00719 working position moving Magezine 97, 99 present it

00720 allow different parts of the upper tool 7

00721 to be put together with a constant

00722 end, fed from the third magazine 98 counter

00723 pieces. 00724

00725 The swiveling movement of the two magazines 97, 99

00726 synchronized in opposite directions by the coupling member 103.

00727 The coupling member 103 can be manually controlled or by

00728 a separate drive can be moved. Basically

00729 the coupling is such that when one is swung in

00730 magazine swings out the other. According to the illustration

00731 a hand-controlled pivoting of the two magazines 00732 97, 99. 39 is the magazine 97 in

00733 working position. The feeder firmly connected to this

00734 approximately rail 100 is by a plug pin 104th

00735 locked, which engages to the lower end

00736 of the feed rail 100. The other feed rail

00737 101 is out of engagement with the assigned

00738 ten, machine frame-side socket pin 105. This means

00739 tet that the functional parts of the push buttons on the

00740 feed rail 100 passed into the jaws 33

00741. Should the other functional parts of a printing

00742 knöpf s are set, so are the magazines 97, 99 so

00743 to pivot their thru axle brackets 87 that

00744 over the Koppelgiied 103 the other feed rail

00745 101 with the bush 68 attached to it in alignment

00746 position reaches the jaws 33. This can

00747 but only happen after loosening the plug pin 104.

00748 After swiveling the magazines, the plug-in

00749 zen 105 the position of the end of the feed rail 101

00750 to the upper tool 7. For an improved support

00751 of the end of the feed rail 100 or 101 extends

00752 on the pin 104, 105 opposite

00753 side a support pin 108, which in a machine frame

00754 side niche 106 swings. 00755

00756 Fig. 37 illustrates in detail

00757 locking of the thru axle 88. The latter forms in the loading

00758 reaches an end of an annular groove 88 'into which a

00759 dowel-side locking pin 107 is inserted. This is

00760 spring-loaded in the direction of its engagement, which is not

00761 is illustrated in more detail. Loosening the thru axle holder

00762 tation therefore requires that this be withdrawn beforehand

00763 locking pin 107, which after lifting the lock

00764 of the end of the corresponding feed rail

00765 men will. 00766 00767 According to the alignment of the axle bracket in the plane

00768 of the side wall 92 of each magazine, it is possible to

00769 designed magazines in 180 ° turned position

00770 zen- The product surface forming the side wall changed

00771 not her location. It would be different accordingly

00772 designed a customized feed rail to the product

00773 assigned magazine. 00774

00775 The machine shown in FIGS. 43-50 is opposed to

00776 slightly modified over the first embodiment.

00777 The same components therefore have the same reference numbers. 00778

00779 Deviating from the first embodiment is now

00780 Position of the cam disc 20 ', 21' to each other. The

00781 one end of the over a larger angle of rotation

00782 extending cam control cam 20 'begins on the same

00783 Height with the cam control cam 21 '. The switch 25 '

00784 and bypass switch 26 'are in line behind one another.

00785 others. The bypass switch 26 'is in the output

00786 position according to FIG. 45 by the cam control cam 20 '

00787 applied so that the bypass switch 26 'opened

00788 net. 00789

00790 Another deviation is that in the fully

00791 constantly shifted position of the rod 55 or

00792 carriage 56 the switch 65 'is actuated. In terms of

00793 the same is the closed position. The actuation

00794 takes place via a wing 56 'of the slide 56.00795

00796 Exclusively in the fully advanced position

00797 the slide 56 or the rod 55 can the Ar-

00798 workflow initiated by foot switch 82

00799. The sled does not take its fully

00800 forward position, the switch 65 'is not

00801 operated in the sense of closing, although the locking 00802 gel of the support platform 46 is present. In the first

00803 embodiment would be the finger protection circuit

00804 activated, i.e. the stage locked. There, however

00805 the plunger movement can be carried out, even if none

00806 button parts are inserted. Therefore, it turns out

00807 modified embodiment as the optimal design

00808 tung- 00809

00810 According to FIGS. 46 and 47, the drive pulley 18 also has

00811 the cam disc cam 20 ', 21' already by a certain

00812 rotated angle of rotation. Along with this, the rivet

00813 holding tool 28 so far that between this

00814 and the support platform 46 the safety distance is present.

00815 It can also be seen from FIG. 47 that the carriage 56

00816 is relocated when switch 65 'is released

00817 opens. The switch 80 remains as shown in FIG. 47

00818 still closed, so that the electric motor 24 continues

00819 is driven. 00820

00821 However, there is a foreign body or a finger

00822 between rivet holder tool and support platform, so

00823 according to the relative storage of riveting tool and

00824 plunger of switch 80 opened. 00825

00826 If the safety distance is maintained, the drive

00827 continued, so that as a further intermediate position Fig. 48

00828 is present. From this it emerges that the support platform

00829 46 already folds downwards. this is possible

00830 as a result of the rod 55 releasing the platform. In

00831 this intermediate position, the switch 80 is still

00832 locks. Before moving the plunger further

00833 switch 80 opens, is from the cam cam

00834 20 'the bypass switch 26 ^* in the closed position

00835 brought so that the drive always continues. 00836 ' 00837 Then the other dead center position of the ram

00838 reached, see Figs. 49 and 50. Fig. 50 shows

00839 the release of the bypass switch 26 ', which

00840 is therefore rather closed. 00841

00842 By further rotation of the drive, the

00843 at 59 the rod 55 carried by the carriage 56 back in

00844 support position brought to the platform 46. At the same time

00845 the rod takes a new lower push button part 54. 00846 The plunger 66 transports an upper one

00847 push-button part 38 in the direction of the rivet holding tool

00848 28. The upward movement of the plunger 6 is ended

00849 according to the action of the switch 25 'by the

00850 cam disc cam 21 *. 00851

00852 Only with rod 55 fully advanced

00853 the monitoring switch 65 'is actuated so that a

00854 new riveting process can take place. 00855
