Description

00001 Device for circulating conveying of parts 00002

The invention relates to a device for

00004 revolving conveying of parts, especially work pieces

00005 ken, along one of parallel bars

00006 th conveyor line, which rods with their ends on

00007 an endlessly closed path are moved, which

00008 path in an acute angle to the bars

00009 level is such that the ends of the

Rods held next to their movement play

00011 movement on the endlessly closed path also one

Carry out longitudinal movement in the conveying direction. 00013

A device of this type is known from EP 0289 845

00015 Bl known. Here the bars form one in rotation

00016 removable cage. They go after a closed

00017 aligned cylinders in the form of round

00018 rods through ball bearing holes of rings,

00019 which produce the endless path by turning. 00020

00021 From EP 0 609 661 Bl the endless web is in shape

00022 an upwardly open trough formed. The ends

00023 of the rods sit like a universal joint on endlessly rotating ones

00024 dreams that led over pulleys or the like

Are 00025. Here the loading takes place over the top

00026 open trough opening, whereas a cage from the forehead

00027 de forth is accessible in this regard. 00028

The object of the invention is to build such systems

00030 to simplify and design more convenient. 00031

00032 This task is initially and essentially at

00033 of a device with the features of claim 1

00034 solved, the focus being on the rods

00035 have their ends insertion holes in which on the 00036 continuous orbiting, parallel to the conveying direction

00037 protruding support bolts with appropriate clearance

00038 th. Due to such a configuration is a device

00039 increased utility value achieved. On the one hand, it lies in

00040 simplified structure and on the other hand in the clamping

00041 justified free running. The plug connection carrying

00042 bolt to hole is not only easy, it is required

00043 also not special security means. The course of the

00044 web secures the connector. The game is both

00045 a tilting game as well as a sliding game, tolerant

00046 the usual movement relationships between

00047 endless track and the bars. A particularly precise final

00048 loose track is reached by chains. The chain brings

00049 also the constructive basis with regard to the

00050 support bolt. Therefore, according to the invention, it is further from

00051 advantage that the support bolts are directed towards each other

00052 on the limbs of two at a distance from each other in the

00053 endless tracks of revolving chains are provided. A

00054 basic chain can be in the bolt assignment in

Convert in no time. It is also envisaged that the

00056 chains over a lower path with a large radius and one

00057 upper path are deflected with a smaller radius. The

00058 leads to a pear shape with a cross section

00059 reason for the inclusion of the parts, especially

00060 special workpieces, including the treatment agent such as

00061 in particular abrasive bodies or for spraying

00062 blast treatment. A design of even

00063 permanent meaning is that the bars as

00064 flat-form strip rod are designed, which end

00065 dig the insertion holes near one longitudinal edge

00066 sen and which on the other longitudinal edge in movable

00067 chem, positive engagement are available to the neighboring

00068 flat-form strip rod. That avoids gaps and that

00069 tendency to a certain clamping effect. It’s

00070 more from bar to bar an overlap area. The 00071 interlocking also leads to one

00072 good carrying of the rods together, apart from the

00073 terminal storage to the parallel tracks. The

The whole of the construction is concretized in that one

00075 longitudinal edge on which the insertion holes are formed

00076 are designed as a thickened profile and one

00077 groove-shaped free space forms for the closing

00078 gripped the other longitudinal edge of the neighboring, identical

00079 table-shaped flat bar. The grooved

00080-shaped free space takes into account the space requirement itself

00081 when the web is deflected in a smaller radius

00082 or chains. The thickened profile gives one

00083 larger material accumulation and thus stability. thereupon

00084 it is further proposed that the flat form strips

00085 rods are equipped with sieve windows. This the

00086 translucent windows are related to

00087 the dimension of the parts can be selected. In particular let

00088 thereby avoid getting caught, for example. So

00089 it is advantageous if the window opening area

00090 is at least the same size as the rest of the closed

00091 sene surface of the flat-form strips bars. Through the

00092 fenestration is caused by wall weakening

00093 fully compensated by grasping the related

00094 Longitudinal edge in the groove-shaped free space. The windows can

00095 even be open there, so that an arithmetic

00096 sheet is available as a inguinal rod. One as well

00097 wear-resistant as well as oversized position-avoiding

00098 armor chain-like structure on the chains

00099 results from simple means that the

00100 support bolts are round pins and the insertion holes as

00101 diaboloidal holes according to the necessary

00102 movement play larger diameter are designed.

00103 What is meant is a hole-centered rotationally symmetrical

00104 support zone, the funnel as it were towards the hole ends

00105 opens. It is also convenient that the insert 00106 holes as the area of the groove-shaped free space

00107 rendes bearing eye is formed. The groove can be used as

00108 additional immersion space can be used for the support bolt

00109 den. There is also a kind of end wall

00110 mes before that connects the two legs of the groove. It

00111 is a kind of bag. A management engineering

00112 is seen in part that the one longitudinal edge

00113 outstanding bearing eye in a square notch

00114 comes along other longitudinal edge. This results in a final

00115 zendes longitudinal play between the

00116 two bars. It is also envisaged that the forehead

00117 the of the flat-form strips rods following that

00118 bearing eye converging into the notches.

00119 A kind of conveying cam is achieved by a

00120 comb with fleeing breast flank on the thickened pro

00121 fil. The protruding thickening of the groin is therefore sensible

00122 used. In terms of drive technology, it proves to be advantageous

00123 that the chain transfer path of smaller diameter

00124 is formed by chain wheels and the two chain wheels

00125 which are connected by a shaft, which with both

00126 chain wheels are connected via universal joints. The

00127 corresponding gimbal drive is free of constraint and

00128 fully takes part in the adjustment movement of the device.

00129 Such an adjustment movement results when swiveling

00130 the cheeks of the device into a rhomboid and also

00131 with subsequent tipping over the feet of the

00132 cheeks to the broadside. It is also proposed

00133 that the chain wheels together with the shaft are the driving force for

00134 initiate the endless circulation. There is also an advantageous

00135 characteristic in that the chain deflection path is large

00136 ren diameter as a chain slideway in the form of a

00137 ring is designed, the openings for loading

00138 or serve for insertion. Continuing education can still do so

00139 that the endless path has one or more

00140 has right deflection points in the curvature direction. 00141 Finally, it is also proposed that the flat 00142 molded strip rods are made of plastic with a reinforced reinforcement. A metallic 00144 reinforcement is expediently used. Finally it proves to be 00145 advantageous that the optionally perforated armature 00146 lies in the thickened profile and consists of a 00148 U-profile circumscribing the groove-shaped free space. Its complete embedding avoids contact between this U-profile and the material to be treated for 00150. 00151 00152 The subject of the invention is explained below with reference to 00153 of a graphically illustrated Ausführungsbeispie00154 les. It shows: 00155 00156 Fig. 1 the device for circulating conveying of 00157 parts in plan view, largely schematized, 00159 00160 Fig. 2 is a vertical section through the device, 00161 showing the course of the endless path, 00162 00163 Fig. 3 is a flat molding Rod in a cut 00164 end view, 00165 00166 Fig. 4 two such rods in positive engagement, 00167 a maximum folding position to each other, for example in a path with a small radius 00169 as a deflection point, 00170 00171 Fig. 5 the same in a path with a large Radius, 00172 00173 Fig. 6 means of the web guide on a ring, with 00174 joint between the bar and chain, 00176 Fig. 7-11 various movement studies of the articulation points 00177 between flat bar and chain, 00178 00179 Fig. 12 is an interior view of the armored chain-like interconnected flat bar bars, 00181 00182 Fig. 13 the same with a view of their ends in 00183 still unconnected state, specifically as a perspective cutout, 00185 00186, Fig. 14 in perspective, a section of the drive 00187 transmission means in perspective, representing a universal joint between 00189 shaft and the driving or driven 00190 chain wheel, 00191 00192 Fig. 15 a variant of the device in front view 00193 with a different course of the endless path and 00194 00195 Fig. 16 another related variant of the Vor00196 direction. 00197 00198 The illustrated device V for the revolving conveying 00199 of parts, in particular workpieces, comprises a 00200 conveying path arrow F. In this direction, loading and spreading lie. 00202 00203 The conveyor line arrow F is composed of bars 1. These are identical flat-form strips 00205 rods 1. They describe a receiving space 2 for the goods to be treated 00206. 00207 00208 The rods 1 are connected via their two ends to a web B closed at end00209. 00210 moves in the direction of arrow x (see FIG. 2). 00211 The flat chain connected

00212 form-bars 1 run parallel to each other, in

00213 aligned essentially horizontally. 00214

00215 The web B extends at an acute angle to the

00216 rods 1 standing vertical plane E-E. The top

00217 angle is designated with alpha (see FIG. 1). 00218

00219 The rods 1 of equal length practice on the basis of this

00220 a shear force in the direction of arrow F

00221 out of the estate, with a final exit

00222 bear in this direction. 00223

00224 Lane B can be moved in another direction

00225 bend, namely from the plane E-E into a vertical

00226 kale leaving inclined position. This tipping happens around

00227 the angle beta (see FIG. 1). The device V is

00228 equipped for these adjustments without these de-

00229 tails to reproduce. It is about such

00230 details referred to EP 0 609 661 B1. 00231

00232 The web B runs on guide means of a cheek 3. Die

00233 is provided in pairs and has the same name.

00234 The web B guided in the left-hand cheek 3 receives

00235 from there its rotary drive via an electric gearbox

00236 be otor 4. It is on the outside of the cheek 3 there

00237 flanged. The rotary drive goes on a pinion.

00238 Specifically, it is a chain wheel 5. The chain

00239 bears the reference number 6. The drive goes synchronously

00240 on a chain 6 of the right-hand cheek 3,

00241 if guided via a chain wheel 5. 00242

00243 drive transmission means is a shaft 7. The latter

00244 stands over universal joints 8 with the chain wheels 5 in

00245 connection. 00246 A look at FIG. 2 shows that the endlessly closed path B is composed of differently curved 00248 sections. The chains 6 are namely deflected 00249 via a lower path B1 with a large radius and a 00250 upper path B2 with a smaller radius. The ratio is approximately 4: 1. The center axis distances of the 00252 tracks B1 and B2 in the form of an arc of a circle are vertically spaced such that an approximately clearly pear-shaped silhouette is created, that is to say with straight sections 9 of the track converging towards the top. 00256 00257 While the chain wheels 5 together with shaft 7 initiate the drive 00258 force for the endless circulation via meshing, 00259 a sliding guide is used for the area of the lower track Bl. The correspondingly acting Ket00261 tengleitbahn 10 provides a ring 11. Both cheeks 3 00262 have such a ring 11. It is indirectly held using 00263 of a groove 12 in a contour-corresponding recess 00264 of the cheeks 3. 00265 00266 The sleeve-like elongated ring 11 can 00267 consist of plastic with embedded reinforcement 13, 00268 for example a perforated metal sleeve. The latter 00269 extends into the plane of the path B, or the 00270 chains 6 (see FIG. 6). The opening 14 of the rings 11 00271 serves, as already indicated, for the loading or 00272 discharge for the material to be treated and the active substance 00273. 00274 00275 According to FIG. 15, the device can also be provided with more than 00276 one chain wheel per cheek 3. 15 00277 indicates three chain wheels 00278 5 mounted above the ring 11 and thus deflection points. The distribution of the deflection 00279 points leads overall to a right-angled course 00280 of the free route sections 9 of the run. 00281 FIG. 16 shows two deflection points for the chains 6 00282, likewise lying above the space-determining 00283 height of the ring 11. Here the free 00284 route sections 9 diverge upwards. 00285 00286 The direction V, which can be spatially brought into a rhomboidal shape V, more precisely its cheeks 3 and struts connecting them articulated 00288, lead through suitably articulated 00289 th chain run that the flat-shaped Leis00291 ten rods 1 held at their ends with 00290 corresponding movement play next to their movement (arrow x) on the 00292 endlessly closed path B also perform a longitudinal movement in the 00293 conveying direction of the conveying path arrow F. 00294 00295 The corresponding articulated movement is such that the rods 1 have insertion holes 00297 15 at their ends. In the engaging on the endless web B umlau00298 fender, protruding parallel to the conveying direction of the conveyor line 00299 arrow F 16 supporting bolts. The game taken into account here is both in the sense of a tilting movement as well as axial sliding mobility, but this 00302 without leaving the insertion holes 15. 00303 00304 The support bolts 16 are directed towards each other and 00305 protrude laterally on the links 17 of two chains 6, 00307, at a distance from one another 00306 of the chains 6 rotating in the endless path. The chain's own hinge pins 18, 00308 are only used in a longer version and somewhat slimmer. Reference is made to FIG. 14. Between two support bolts 16 lying in the direction of movement x there are two short articulation bolts 18 on the right side 18. The corresponding repeat is maintained throughout 00312. 00313 00314 The center distances of two support bolts 16 define the 00315 hole spacing of two adjacent flat-form strips 00316 1 in functional assignment. For this purpose, it has been done in such a way that the rods 1 have the insertion holes 15 in the end near one of the 00318 longitudinal edges a and which 00319 rod 1 on the other longitudinal edge b is in movable, form00320 coherent engagement with the adjacent flat-shaped Leis00321 ten rod 1. Reference is made to FIG. 4. One 00322 longitudinal edge a, on which the insertion holes 15 are formed, is designed as a sufficiently thickened profile, roughly comparable to a Y profile. The two diver00325 yawing legs open towards the longitudinal edge a with 00326 diverging flanks, providing a groove-shaped 00327 free space 19. It is dimensioned such that there is sufficient 00328 de folding ability of the rods 1 to be able to pass even narrower 00329 deflection points. 00330 00331 The other longitudinal edge b or the edge area there 00332 represents the tongue that dips into the groove. The edge area 00333 rich, practically formed by the Y-bridge protrudes with tilt play 00334 at a clear overlap distance Ü into the free space 19 00335. 00336 00337 The Y-web provides a relatively large-area bar 00338 pen 20. It can be stiffened at intervals by a strut 21 which practically conveys a 00339 T-profile. 00340 00341 The flat-form strip bars 1 are then equipped with sieve fens00342 tern 22. Reference is made to FIG. 12. 00343 Between two, approximately square outline, send to neighboring windows 22 there is a frame member 00345 kel 23. Its longer extension is essentially perpendicular to the geometric axis of the insertion holes 15. The frame legs 23 are rooted in the edge area forming the spring 00348, approximately leg-wide the longitudinal 00349 edge b. 00350 00351 Fig. 12 also shows a variant. It is on

00352 the top two bars 1 referenced the smaller window

00353 22 have, so result in a more closely meshed sieve. The

00354 reference numerals are used analogously. The two

00355 upper rods 1 also show a modification in the sense

00356 different widths of the frame legs 23. Die

00357 wider frame legs can the above-mentioned strut

00358 be 21 on the underside, yielding a transverse

00359 cut T-shaped profile. 00360

00361 A configuration can also be advantageous here,

00362 which is designed so that the window opening area

00363 is at least as large as the rest of the closed

00364 sene surface of the flat-form strip rods 1, their rod

So 00365 lapped 20. 00366

00367 The insertion solutions implemented on the rods 1

00368 rather 15 are designed as a kind of bearing eye 24. The-

00369 ses crosses the area of the groove-shaped free space 19.

00370 As can be seen, for example, from FIGS. 3 and 13,

00371 are the outer part protruding beyond the longitudinal edge a

00372 en of the bearing eye 24 in the joint-forming interlocking

00373 nesting of bars 1 not in the way. The long edge

00374 b of the spring-forming rod tab 20 has a notching

00375 and 25. In the comes the protrusion of the bearing eye

00376 24 articulated under. The back of the eye is

00377 on the order side concentric to the bottom of the tilting bearing

00378 forming free space 19 rounded. 00379

00380 The corresponding joining of the rods 1 is also clear

00381 from Fig. 12. From this illustration is moreover

00382 can be seen that the ends of the Flachfor -Listen-

00383 rods 1 converging after the bearing eye 24

00384 rend into the notches 25. So it turns out

00385 a well matching the oblique offset of the cheeks 3, 00386 planing effect excluding guide to ring 11

00387 out. The area of the front edge is immersed on all sides

00388 a step recess 26 (see FIG. 6). This rota-

00389 step recess 26 provided symmetrically

00390 the outside of the ring 11 close to the face takes one

00391 steeply inclined course to the groove of the chain sliding track 10

00392 out. As can be seen in FIGS. 7 to 11, according to FIG

00393 such overlap ratios, all emerging

00394 constellations of ring 11 and track B considered.

00395 Figures 9 and 10 show this in the conveying direction of the

00396 conveyor line arrow F lying play z of slightly less

00397 is longer than the clearance length of the supporting bolt 16.

00398 to limit the sliding in the tongue and groove engagement

00399 the bars 1 act the walls of the terminal storage

00400 gen 24 for the support bolts 16. On the section sections

00401 ten 9 the strands can be stretched in the

00402 pull the rods 1 further outwards. hereby

00403 creates a "threading" free space for the supporting bolts 16

00404 or a release path for the removal of bars,

00405 for example for the purpose of exchange. The chains-

00406 Tension of the chains 6 secures the plug connection 15/16

00407 the free route section 9 of train B. 00408

00409 Between the step recess 26 and the trench-like

00410 chain slide 10 there is a dam 27 of such

00411 height that the support pin 16 does not touch, but the

00412 chain links or their links link him

00413 leads support. At the level of the horizontal flank of the

00414 recess 26 goes to the flat-form bar 1

00415 a inguinal comb 28 over. The face is slanted

00416 cut back to provide an immersion bay 28 '

00417 for the lower ring end 11 'in the area of

00418 step recess 26. The inguinal crest 28 is wider

00419 triangular cross section. It is an incorrect

00420 regular triangle such that the inguinal crest 28 00421 forms a fleeing breast flank 29. This additional

00422 material accumulation, practically forming the upper Y-bridge,

00423 results in an entrainment bead, which however is reached

00424 half the height of the lower track Bl the sliding of the

00425 Allowing good things. 00426

00427 The thickened profile is also further developed

00428 stalt that the flat-form strips bars 1, formed from

00429 plastic, have an embedded reinforcement 30.

00430 It is a U-profile, preferably made of metal.

00431 Its assignment is such that in the area of the thickened

00432 ten profile, so with its U-leg in

00433 essentially lies in the Y-legs and with the

00434 U-bridge lies at the transition area to the Y-bridge. That makes

00435 a stabilizing circumscribing the free space 19 embedded

00436 sation. 00437

00438 Regarding the desired play between the

00439 compared to the hinge pin 18 offset support pin

00440 16, realized as a round spigot, and the rod 1 is

00441 lent the insertion holes 15 a special configuration

00442 applied, namely a diabolic. The plug-in

00443 hole 15 has protruding entrances and exits.

00444 There is a load-bearing comb halfway through the hole.

00445 Figures 7 ff. Showing the one to be drawn from this

00447 support bolt 16 and insertion hole 15. The corresponding

00448 uniform rounding is based on a circular line 31

00449 clarifies. The radius of this circular line corresponds

00450 one and a half times the diameter of the insert

00451 hole 15 in the narrowest cross-sectional central plane of the

00452 Loches. The corresponding rounding is rotationally symmetrical

00453 made trically. Avoids the pleasing curvature

00454 also any planing effect if, for example, the

00455 support bolt 16 in relation to its insertion hole 15 00456 drifts due to drive and not the full immersion depth

00457 takes what is in certain constellations of rods
