Description
Technical field
The present invention relates to a kind of being used for by transmitting the transfer system that carriage (conveyance carriage) comes conveying work pieces, relate more specifically to a kind of like this transfer system, it can increase or reduce the distance of waiting to transmit workpiece according to the layout in the place that is combined with this transfer system.
Background technology
If factory has the operation of a plurality of processing works, then usually will be corresponding to the Fabricating machinery of each operation along straight-though arrangement.Use has along the transfer system of the linear transport path of Fabricating machinery extension, with conveying work pieces between Fabricating machinery.
A kind of being used for for example is conveyor system along the transfer system of straight line path conveying work pieces.
Proposed a kind of by technology (for example, referring to Japanese kokai publication sho patent gazette No.55-66414) with a plurality of conveyer interconnection formation transfer paths.According to the technology of this proposition, overlapping owing between adjacent conveyer, needing, so the complex structure of this transfer path, and it can only be along a direction conveying work pieces.
In being combined with the factory of these transfer systems, assemble transfer system usually individually for the layout of Fabricating machinery.This is because of the distance that can not change neatly by traditional transfer system institute conveying work pieces.
Therefore, for example when desire changes the layout of Fabricating machinery, must assemble new transfer system or revise existing transfer system.
If workpiece is transmitted by a series of conveyers, then can freely select to wait to transmit the distance of workpiece by the quantity that increases or reduce institute's use conveyer.Yet, need other device between conveyer, to transmit workpiece.This transfer device has limited the speed of conveying work pieces, and is tending towards damaging the workpiece that is transmitted.
Also proposed a kind of technology that is used to transmit carriage, this transmission carriage is power (for example, referring to Japanese Patent No.2536799) to act on the electromagnetic force that is arranged sequentially in the linear electric machine on the transfer path and is installed between the magnet on this transmission carriage.
Because transfer system is provided with obstacle for this motion, move transverse to the direction of transfer system so prevented edges such as people, forklift.If people, forklift etc. need move to the opposite side of transfer system, then they need arrive the end of transfer system, and walk around this end of transfer system, thereby arrive the expectation destination.If the total length of transfer system is longer, then they need very long detouring, and therefore the sport efficiencies in factory such as people, forklift are lower.In order to allow people, forklift etc. to move glibly, the part of transfer system can be placed on a higher position, under it so that they pass through.
For the part with transfer system is placed on a higher position, need a special structure between this higher position and other lower position, to transmit workpiece.For example, need the vertical elevator structure that transmits to connect these higher and lower positions.Should vertical transmit elevator structure and make the total system complexity, and need the supporting process of extra transmission workpiece, the result has reduced the speed of conveying work pieces.
A solution is to connect higher position and lower position in the workpiece transfer system by wheel chair access slant path, with conveying work pieces continuously between this higher position and lower position.A kind of technology that is used for continuous conveying work pieces between higher position and lower position is disclosed among the Japanese Patent No.2536799 that for example, quotes in the above.

The process of making the connecting rod 1 of carrying out above-mentioned action comprises: compression process is used for compression and increases its end; And perforation procedure, be used for forming than small through hole 2 with than large through-hole 4 in the corresponding end that increases.Workpiece to be processed directly is placed on the belt conveyor, and is sent to the bench board that carries out perforation procedure from the bench board that carries out compression process.
If workpiece to be processed directly impinges upon on the belt conveyor, then workpiece is damaged easily owing to impact.
For in the enterprising eleven punch 11 process of workpiece, the workpiece that is positioned on the belt conveyor is clamped and is supplied with driling unit by transfer device.Because workpiece random position on belt conveyor, and a surface of workpiece is being held against belt conveyor, so transfer device clamping work pieces easily.If transfer device does not have the expectation part of clamping work pieces, then concerning driling unit, just be difficult in the desired locations and form than small through hole 2 with than large through-hole 4.In other words, if bring the transmission workpiece to be processed by transmission, then manufacturing process has such shortcoming, that is, can not form than small through hole 2 with than large through-hole 4 with higher precision.
According to other method, workpiece to be processed is placed on the anchor clamps, and these anchor clamps are holded up and in conveyer belt with conveying work pieces.Yet these anchor clamps may drop.
Known also do not have document to disclose a kind of desirable technology, is used for transmitting elongated workpiece along conveyor line with orthostatism.
If the transmission carriage of at high speed motion stops suddenly, then may make at the workpiece that transmits on the carriage and damage or damage owing to be applied to the impact on the transmission carriage.For fear of these shortcomings, wishing to transmit carriage should stop as far as possible slowly.
Consider above-mentioned requirements, proposed various speed control mechanism and the various stop control mechanisms that are used to control the speed that transmits carriage.The document that discloses speed control mechanism comprises for example Japanese kokai publication sho patent gazette No.56-50860 and Japanese kokai publication hei patent gazette No.9-263238, and the document that discloses stop control mechanism comprises for example Japanese patent gazette No.58-41250.These disclosed mechanisms all are set to reduce the speed that transmits carriage, to stop to transmit carriage lentamente.
According to disclosed technology in Japanese kokai publication hei patent gazette No.9-263238, transmit roller setting in motion or the stop motion of carriage on being installed in chain.Therefore, this transmission carriage can only move along rectilinear direction, and can not change its direction.And the distance of this transmission movement of bracket can not be greater than the distance by this chain provided.
Particularly, the traditional speed control mechanism or the stop control mechanism that are used to transmit carriage are used to stop at the transmission carriage of motion in the limited range, and can not stop at the transmission carriage of advancing in the transfer assembly, and this transfer assembly can reverse its direction.
In addition, be set to advance once more apace owing to can not transmit carriage, so its cost a very long time conveying work pieces, thereby very low by the efficient of its conveying work pieces.

The operation of each parts of the transfer system 10 of structure like this will be described below.At first, wherein will unite carriage assembly 12 is transferred to horizontal transfer unit 16b from horizontal transfer unit 16a the process that transmits with being described with reference to Figure 24.
The motor 32 of horizontal transfer unit 16 and the motor 164 of inclination delivery unit 18 are switched on, thus rotation at a predetermined velocity, to drive endless chain 30 circularly.When line of centers C (see figure 2) is observed, endless chain 30 and endless chain 162 are driven by the cw circulation.
When uniting when transmitting carriage assembly 12 and being arranged in horizontal transfer unit 16a, unite first to the 3rd lower surface that transmits the chain pressing plate 242 of carriage 200,202,204 that transmits carriage assembly 12 and under the elasticity of spring 244, push chain roller 30a (seeing Figure 16).Since the chain roller 30a of endless chain 30 horizontal upward guide piece 40 upper surface on roller moving, so chain pressing plate 242 is according to the roller principle and horizontal motion.As a result, first to the 3rd transmits carriage 200,202,204 along being transmitted by the direction shown in the arrow B, transmits the 4th transmission carriage 206 that carriage 204 engages by pipe link 208 pullings and the 3rd.
At this moment, because chain pressing plate 242 pitch of fully being longer than endless chain 30, the distance between promptly adjacent two chain roller 30a, so the lower surface of chain pressing plate 242 always is being held against a plurality of chain roller 30a, and be difficult for and chain roller 30a produces vibration synchronously.Because the front end along the direction of transfer of the lower surface of chain pressing plate 242 is an arc, so chain roller 30a is incorporated in the gap between chain pressing plate 242 and the horizontal upward guide piece 40 smoothly.
Then, unite the front end that transmits carriage assembly 12, promptly first transmit the end that carriage 200 is sent to horizontal transmission bracket unit 16a, herein, first transmits carriage 200 is released from endless chain 30.At this moment, because second chain pressing plate 242 and the endless chain 30 that transmits carriage 202 and the 3rd transmission carriage 204 kept in touch, therefore unite and transmit carriage assembly 12 by the continuation transmission.
First transmits carriage assembly 200 continues to be transmitted along guide rail 28, and transfers to horizontal transfer unit 16b from horizontal transfer unit 16a.At this moment, because the junction between the guide rail 28 of horizontal transfer unit 16a, 16b has the continuous upper surface in no step and gap, therefore the first transmission carriage 200 can pass through this junction reposefully, and unites the speed that transmits carriage assembly 12 and can not reduce.
Then, the second transmission carriage 202 is transferred to horizontal transfer unit 16b from horizontal transfer unit 16a.At this moment, have the final the 4th of chain pressing plate 242 and transmit the end that carriage 206 arrives horizontal transfer unit 16a, and discharge from endless chain 30.Provide power although do not transmit carriage 206 to the 3rd from horizontal transfer unit 16a, but, therefore unite and transmit carriage assembly 12 quilt continuation transmission because the first transmission carriage 200 and the chain pressing plate 242 of the second transmission carriage 202 and the endless chain 30 of horizontal transfer unit 16b are kept in touch.
Subsequently, the 3rd transmission carriage 204 and the 4th transmits carriage 206 and is transferred to horizontal transfer unit 16b, so, unite transmission carriage assembly 12 and just on horizontal transfer unit 16b, transmit.
Described above unite the process that transmits carriage assembly 12 along transmitting by the direction shown in the arrow B.Unite and transmit carriage assembly 12 along transmitting (see figure 2) in an identical manner by the direction shown in the arrow A.Particularly, transmit carriage assembly 12 reverse leadings if will unite, and endless chain 30 contrarotation in Figure 24, then be appreciated that, unite and transmit carriage assembly 12 along transmitting reposefully by the direction shown in the arrow A, the same when transmitting with it by the direction shown in the arrow B.
Transmit carriage assembly 12 when horizontal transfer unit 16a transfers to horizontal transfer unit 16b when uniting, do not need workpiece is mounted thereto or remove from it.
Describe wherein to unite below with reference to Fig. 3 and transmit carriage assembly 12 through being arranged on the process of two inclination delivery units 18 between the horizontal transfer unit 16.
When uniting the front end that transmits carriage assembly 12, when promptly the first transmission carriage 200 was near inclination delivery unit 18, the 4th transmitted the roller 270 abuts ramp surface 56a of carriage 206, and this inclined-plane is as the lower surface on lobe plate 56 ends.Be transmitted along with uniting transmission carriage assembly 12, roller 270 is pressed downward along inclined-plane 56a, and arrives parallel faces 56b, and roller 270 keeps being pushed (seeing Figure 12) downwards with uniform depth herein.
When roller 270 is subjected to the squeese pressure of lobe plate 56, the spring 262 (seeing Figure 13) of roller 270 compressible drive power transmission apparatus 256, thus make pendulum plate 260 move about front axle 220 angledly and descend.
When pendulum plate 260 descended, small frame 266 also was lowered, so that side toothed chain wheel 266d on the lower surface of small frame 266 and endless chain 30 mesh.
At this moment, the tooth of the tooth of side toothed chain wheel 266d and endless chain 30 homophase each other.If the tooth of side toothed chain wheel 266d and the tooth of endless chain 30 be out-phase each other, then since side toothed chain wheel 266d substantially vertically near endless chain 30, so the tooth top of side toothed chain wheel 266d is on the corresponding chain roller 30a of endless chain 30.Because spring 268 is compressed, the tooth of side toothed chain wheel 266d can exceedingly not push chain roller 30a, has therefore prevented that side toothed chain wheel 266d, chain roller 30a and lobe plate 56 are damaged.
At first, when small frame 266 is lowered, if the tooth of side toothed chain wheel 266d and the tooth of endless chain 30 be out-phase each other, and the tooth of side toothed chain wheel 266d is on the corresponding chain roller 30a of endless chain 30, then be transmitted subsequently along with uniting transmission carriage assembly 12, the tooth of side toothed chain wheel 266d and the tooth of endless chain 30 be homophase naturally each other, thereby side toothed chain wheel 266d and endless chain 30 mesh.
Then, first transmits carriage 200 crosses drive sprocket 36 motions, and the first chain pressing plate 242 that transmits carriage 200 discharges from endless chain 30.First transmits carriage 200 does not receive propulsive effort, promotes but transmit carriage 202 by pipe link 208 by second, thereby is continued to transmit.Afterwards, second transmits carriage 202 and the 3rd transmits carriage 204 successively from endless chain 30 releases, and transmits carriage 206 by the 3rd and release.
At this moment, because the 4th side toothed chain wheel 266d that transmits carriage 206 keeps engagement with endless chain 30, thereby therefore the 4th transmit the propulsive effort that carriage 206 receives from endless chain 30 and be transmitted, and transmit carriage 200,202,204 releases first to the 3rd.
First to the 3rd transmits carriage 200,202,204 beginnings is raised along inclination intake section 160a.At this moment, resist gravitational motions,, can upwards advance along inclination intake section 160a reliably so unite transmission carriage assembly 12 because the 4th side toothed chain wheel 266d and the endless chain 30 that transmits carriage 206 keeps meshing although unite transmission carriage assembly 12.And, but because first to the 4th transmission carriage 200,202,204,206 by joint 230 interconnection of vertical oscillation, is transmitted along inclination intake section 160a reposefully so unite transmission carriage assembly 12.
First transmits carriage 200 is transferred to constant inclination part 160c from inclination intake section 160a.At this moment, because the release part 172a (see figure 3) of driven sprocket 172 is positioned to the upper surface a little less than guide rail 160, therefore the first side toothed chain wheel 246 that transmits carriage 200 is obliquely near endless chain 162 and be engaged with.Along with the close obliquely endless chain 162 of side toothed chain wheel 246, they automatically mesh each other.Therefore, side toothed chain wheel 246 and endless chain 162 engagement reliably each other.
As shown in Figure 3, when side toothed chain wheel 246 and endless chain 162 mesh each other reliably (perhaps after their engagements soon), the 4th roller 270 that transmits carriage 206 is crossed lobe plate 56 motions, and discharges from lobe plate 56.Roller 270, pendulum plate 260 and small frame 266 discharge from the squeese pressure of lobe plate 56, and upwards return under the elasticity of spring 262.At this moment, side toothed chain wheel 266d discharges from endless chain 30.
After endless chain 30 discharged, side toothed chain wheel 266d was promoted by endless chain 162 at side toothed chain wheel 266d.Therefore, second to the 4th transmit carriage 202,204,206 by 200 pullings of the first transmission carriage.
At this moment, be supported on reliably on the guide rail 160 by last roller 216 and lower roller 218, so, also can transmit to unite and transmit carriage assembly 12 even constant inclination part 160c sharply tilts because unite transmission carriage assembly 12.If side toothed chain wheel 246, endless chain 162 and pipe link 208 etc. are enough firm and motor 164 produces enough propulsive efforts, then the constant inclination part 160c ground that can with respect to the horizontal plane meet at right angles is directed.
Afterwards, unite transmission carriage assembly 12 processes and have the constant inclination part 160c and the middle part 160b of sloped of upstroke, and enter the constant inclination part 160d that has to descending slope.Have in the constant inclination part 160d of descending slope,, therefore prevented to unite and transmitted carriage assembly 12 owing to gravity glides because side toothed chain wheel 246 keeps engagement with endless chain 162.
Then, transmitting carriage 200 arrival first has to the constant inclination part 160d of descending slope and the junction between the inclination intake section 160e, promptly arrive before the end of inclination upward guide piece 174, the 4th roller 270 that transmits carriage 206 abuts against the end of lobe plate 180, i.e. its inclined-plane 180a.
Advance forward along with uniting transmission carriage assembly 12, roller 270 is lowered by the inclined-plane 180a and the parallel faces 180b of lobe plate 180.At this moment, the mode of motion of roller 270 is the same when reducing by lobe plate 56.When roller 270 was lowered, side toothed chain wheel 266c and endless chain 162 meshed.If this moment side toothed chain wheel 266c and endless chain 162 out-phase each other, then spring 268 is compressed, and the tooth of side toothed chain wheel 266c can exceedingly not push chain roller 162a (see figure 5), has therefore prevented that side toothed chain wheel 266c, chain roller 162 and lobe plate 180 are damaged.Along with uniting the transmission that transmits carriage assembly 12, side toothed chain wheel 266c and endless chain 162 carry out homophase each other naturally and are engaged with each other.
Then, first transmits carriage 200 crosses drive sprocket 170 processes, and enters the inclination intake section 160e that has to descending slope.At this moment, the first side toothed chain wheel 246 that transmits carriage 200 discharges from endless chain 162.Owing to the 4th side toothed chain wheel 266c and the endless chain 162 that transmits carriage 204 keeps engagement, therefore prevented to unite transmission carriage assembly 12 and glided.
The gear reducer (not shown) of motor 164 can be combined with a free-wheel clutch, is used for preventing to unite transmission carriage assembly 12 when generations such as unexpected electric power fault and glides.
As shown in Figure 4, unite and transmit carriage assembly 12 and move through inclination delivery unit 18 and go forward side by side into horizontal transfer unit 16, this horizontal transfer unit 16 is arranged to surpass inclination delivery unit 18 and coupled.In horizontal transfer unit 16, first transmits carriage 200 moves on horizontal upward guide piece 40, and the chain roller 30a (see figure 5) of endless chain 30 is sandwiched between the chain pressing plate 242 of the horizontal upward guide piece 40 and the first transmission carriage 200.Because chain pressing plate 242 has the lower surface that has the arc front side, so endless chain 30 is incorporated under the chain pressing plate 242 smoothly.Afterwards, the first transmission carriage 200 is transmitted under the power effect that is applied by endless chain 30.Then, the second chain pressing plate 242 that transmits carriage 202 also arrives horizontal upward guide piece 40, and the second transmission carriage 202 also is subjected to the conveying capacity from endless chain 30.
Then, the end process that the 4th roller 270 that transmits carriage 206 crosses lobe plate 180, and from lobe plate 180 releases.Roller 270, pendulum plate 260, small frame discharge from the squeese pressure that is applied by lobe plate 180 for 266 this moments, and upwards return (seeing Figure 11) under the elasticity of spring 262.Side toothed chain wheel 266c discharges from endless chain 162 this moment.Although the 4th transmits carriage 206 because gravity is tending towards gliding, because at least the first transmit the chain pressing plate 242 extruding endless chains 30 of carriage 200, so it is supported by friction force to unite transmission carriage assembly 12.Therefore needn't make to unite and transmit carriage assembly 12 acceleration.
Therefore, unite and transmit carriage assembly 12, comprise that promptly the 4th all that transmit carriage 206 transmit carriages and all enter horizontal transfer unit 16, and the power that receives by from first to the 3rd chain pressing plate 242 that transmits carriage 200,202,204 and continued to transmit.
In transfer system 10 according to the embodiment of the invention, as mentioned above, by making the first side toothed chain wheel 246 that transmits carriage 200 keep engagement, unite transmission carriage assembly 12 and can between horizontal transfer unit 16 and inclination delivery unit 18, pass through continuously with the endless chain 162 that is supported on the inclination upward guide piece 174.Need be between horizontal transfer unit 16 and inclination delivery unit 18 the Assembly ﹠Disassembly workpiece.Unite transmission carriage assembly 12 by making the 4th side toothed chain wheel 266d that transmits carriage 206 keep engagement to transmit, thereby can be pushed to reliably on the upward slope zone of inclination delivery unit 18 uniting the front portion of transmitting carriage assembly 12 with endless chain 30.
In the descending zone of inclination delivery unit 18, though at side toothed chain wheel 246 after endless chain 162 discharges because the 4th side toothed chain wheel 266c that transmits carriage 206 keeps engagement with endless chain 162, therefore also can prevent to unite and transmit carriage assembly 12 downslides.
In the above-described embodiments, the guide rail 160 of inclination delivery unit 18 has the arcuate shape that raises up.Yet the guide rail 160 of inclination delivery unit 18 is not limited to this shape, but can comprise a horizontal zone in the middle.Inclination delivery unit 18 can be for only having sloped of upstroke or to the shape of descending slope, perhaps has sloped of upstroke or to descending slope and the combined shape of horizontal component.
In transfer system 10 according to the embodiment of the invention, as mentioned above, when the 3rd transmits carriage 204 and arrives the terminal of range of movement of the endless chain 30 in horizontal transfer unit 16a, because at least the first chain pressing plate 242 that transmits carriage 200 has been transferred to contiguous horizontal transfer unit 16b, transmit carriage assembly 12 by the continuation transmission so unite.
Transmit carriage assembly 12 when horizontal transfer unit 16 is transferred to inclination delivery unit 18 when uniting, unite and transmit carriage assembly 12 and promote by the side toothed chain wheel 266d that transmits carriage 206 with endless chain 30 ingears the 4th, and by transmitting the side toothed chain wheel 246 of carriage 200 with endless chain 162 ingears first and being continued to transmit.
And, transmit carriage assembly 12 when inclination delivery unit 18 is transferred to horizontal transfer unit 16 when uniting, prevent to unite transmission carriage assembly 12 by side toothed chain wheel 266c and glide with endless chain 162 ingears the 4th transmission carriage 206, and by being held against chain pressing plate 242 and the quilt continuation transmission that first of endless chain 30 transmits carriage 200.
Because last roller 216 and lower roller 218 rotate along the end face of guide rail 28 and guide rail 160, be stabilized and transmit continuously so unite transmission carriage assembly 12.
And, because horizontal transfer unit 16 and inclination delivery unit 18 are separated from one another, thus can increase or reduce the quantity of horizontal transfer unit 16 and inclination delivery unit 18 according to the layout of the machining tool that is adopted, thus regulate transmission distance.Because horizontal transfer unit 16, inclination delivery unit 18 and oppositely unit 20 is separable each other and can connect, so they can assemble and manage easily, and can easily change when et out of order.
In the factory that makes these unit, can manage these unit in order to assembling and quality control.Owing to after the operability of these unit of test, transport, so can be in these unit of on-site installation in the time period that reduces.
By using connecting panel 120, pillar 22 and bolt 61 that horizontal transfer unit 16 is connected to each other simply and separating.Unnecessary separation and processing motor, horizontal transmission endless chain etc.Also can in an identical manner horizontal transfer unit 16, inclination delivery unit 18 and reverse unit 20 be interconnected and separate.Horizontal transfer unit 16 should preferably have the length of about 2m.
Each horizontal transfer unit 16 all has two guide rails parallel to each other 28 ( guide rail 28a, 28b) and two endless chains 30,33 corresponding to respective track 28, and these two endless chains 30,33 rotate along opposite direction respectively, are used for uniting transmission carriage assembly 12 along working direction and reverse the transmission.
Usually, after working direction (direction of progress path) conveying work pieces, unite transmission carriage assembly 12 and return along opposite direction (direction of return path) usually.Because single horizontal transfer unit 16 can be along working direction and reverse conveying work pieces, so horizontal transfer unit 16 has been saved the space.Inclination delivery unit 18 also can be along working direction and reverse conveying work pieces.
Guide rail 28,160 is the form along the direction of transfer elongated board.Unite and transmit carriage assembly 12 transverse to guide rail 28,160 motions, and at the side carrying workpiece with respect to guide rail 28,160.Therefore, workpiece can be installed in to unite on the side in bench board 26 that transmits carriage assembly 12 or workpiece is removed from this side.
In above-mentioned example, the motor 32 in a plurality of horizontal transfer unit 16 is with identical speed rotation.Yet these motors 32 can be with different speed rotations.In this case, uniting the chain pressing plate 242 and the chain roller 30a that transmit carriage assembly 12 can pass through on the junction between the horizontal transfer unit 16 when sliding a little each other.
Because inclination delivery unit 18 has the shape that raises up,, pass through betwixt to allow people, forklift etc. so provide a space in inclination delivery unit 18 bottom center.
Below with reference to Fig. 5 and Fig. 7 the operation that makes endless chain 30,33 cycle rotations by motor 32 is described.
The motor 32 of horizontal transfer unit 16 is with predetermined speed rotation, and its propulsive effort transfers to driving finishing bevel gear cuter 94 by coupler 96 and outrigger shaft 92 (see figure 6)s.Clickwise when driving finishing bevel gear cuter 94 is observed from the top.First driven wheel of differential 72 and second driven wheel of differential 74 mesh with driving finishing bevel gear cuter 94 maintenances, and are driven by the rotation of transmitting from driving finishing bevel gear cuter 94.First driven wheel of differential 72 is released its top direction shown in the arrow B in Fig. 5, and second driven wheel of differential 74 is released its top direction shown in the arrow A in Fig. 5.As a result, first driven wheel of differential 72 clickwise in Fig. 7, and the anticlockwise direction rotation in Fig. 7 of second driven wheel of differential 74.
First driven wheel of differential 72 also as one man rotates with it and be fixed on the driving of first on first S. A. 68 finishing bevel gear cuter 36 around 68 rotations of first S. A..The last machinery (run) of endless chain 30 is drawn in, and the following machinery of endless chain 30 is pushed out.Therefore, endless chain 30 direction shown in the arrow B in Fig. 7 is moved on horizontal upward guide piece 40.
Second driven wheel of differential 74 is around 70 rotations of second S. A., and second drive sprocket 37 that is fixed on second S. A. 70 also as one man rotates with it.The following machinery of endless chain 33 is drawn in, and the last machinery of endless chain 33 is pushed out.Therefore, endless chain 33 direction shown in the arrow A in Fig. 7 is moved on horizontal upward guide piece 40.
Therefore the two ends of first S. A. 68 are rotatably supported by bearing 78 and bearing (first neck bearing) 67a, and can stablize and rotate smoothly and bear big load.Therefore equally, the two ends of second S. A. 70 are rotatably supported by bearing 79 and bearing (second neck bearing) 67b, and can stablize and rotate smoothly and bear big load.
Because bearing 67a, 67b be contained in the bear box 66, so they can be easy to handle, and can effectively utilize the space between first driven wheel of differential 72 and second driven wheel of differential 74.Can utilize retaining element 80 bearing 78,79 easily to be installed in the appropriate location from the outside of guide rail 28.
Have only first driven wheel of differential 72, second driven wheel of differential 74, gear case 66 and driving finishing bevel gear cuter 94 to be arranged between first drive sprocket 36 and second drive sprocket 37, thereby can reduce the gap between first drive sprocket 36 and second drive sprocket 37.That is, reduce the distance between endless chain 30 and endless chain 33, thereby reduced by 16 width of horizontal transfer unit.
Because first S. A. 68 and second S. A. 70 are coaxially to each other, so first drive sprocket 36 and second drive sprocket 37 are also coaxially to each other.Corresponding two driven sprocket 38 (see figure 7)s also are supported on the common support axle 38.Therefore, endless chain 30 provides identical transmission distance and symmetric arrangement with endless chain 33.This layout makes and is easy to horizontal transfer unit 16 is constituted one unit, and is easy to connect and separation of level delivery unit 16.
Be arranged on the line with the axis normal of first S. A. 68 and second S. A. 70 owing to drive finishing bevel gear cuter 94 and motor 32, therefore the size of first S. A. 68 and second S. A. 70 can freely be set.Adopt this layout, motor 32 is outstanding along the direction of first S. A. 68 and second S. A. 70, passes through on the sidepiece of guide rail 28 thereby allow to unite transmission carriage assembly 12.
As mentioned above, drive finishing bevel gear cuter 94 by motor 32 rotations, and first driven wheel of differential 72 and second driven wheel of differential 74 are by rotating from the rotation that drives finishing bevel gear cuter 94 transmission.First driven wheel of differential 72 and second driven wheel of differential 74 can be along the direction rotations of respective opposite.Therefore, endless chain 30,33 can by with first driven wheel of differential, 72 consistent first drive sprockets 36 that rotate and with second driven wheel of differential 74 consistent rotate second drive sprocket 37, and on horizontal upward guide piece 40, move along the direction of respective opposite.As a result, endless chain 30,33 can be in two directions, and promptly working direction and reverse the transmission are united transmission carriage assembly 12.
And, transmit carriage assembly 12 transverse to described outside transmission owing to unite to guide rail 28 or 160, it is not hindered along vertical direction.Therefore, can transmit slender piece (for example, connecting rod 1 etc.) with erectility, and can be along direction of transfer or laterally projecting.Therefore, can transmit elongated relatively workpiece.
Drive finishing bevel gear cuter 94 and can be positioned to transverse to first driven wheel of differential 72 and second driven wheel of differential 74 or below them, rather than the top.Each drives finishing bevel gear cuter 94, first driven wheel of differential 72 and second driven wheel of differential 74 and can be made of any finishing bevel gear cuter (for example, spiral bevel gear, screw bevel gear etc.).Because first driven wheel of differential 72 and second driven wheel of differential 74 can be for can changing the structure of the hand of rotation that drives finishing bevel gear cuter 94, so they can be made of axle side gear, crown gear etc.
Described bearing is not limited to rolling element bearing, and can be plain bearing.
The operation of reverse unit 20 is described to Figure 15 below with reference to Figure 12.In the present embodiment, suppose along transmitting uniting of advancing by the direction shown in the arrow A in Fig. 2,12 and 15 carriage 12 reverse by reverse unit 20, and along advancing by the direction shown in the arrow B.
Because progress path chain 330 is lined up sequence (seeing Figure 12) around reverse unit first driven sprocket 392 that is arranged in the reverse unit 20, therefore oppositely unit first driven sprocket 392, reverse unit second driven sprocket 394 and S. A. 404 also rotate.Make S. A. 370,376 rotations of first dish, 374 and second dish around the chain 400 of lining up sequence by the minor sprocket 396 of S. A. 404 rotations and hinge wheel 398.Therefore, additional thrust mechanism 390 also operates, and no matter first dish, 374 and second dish 376 unite transmits carriage assembly 12 and whether arrives reverse unit 20 and all continues to rotate.
As mentioned above, unite the last roller 216 and the lower roller 218 that transmit carriage assembly 12 and keep progress path, and chain pressing plate 242 (seeing Figure 17) extruding is recycled the progress path chain 330 of operation.Therefore, unite and transmit carriage assembly 12 in by progress path guide rail 28a guiding, by progress path chain 330 along moving by the direction shown in the arrow A among Figure 12.
When uniting when transmitting carriage assembly 12 and advancing to reverse unit 20, the first chain pressing plate 242 that transmits carriage 200 is transformed into the chain 330 of reverse unit 20 from the chain 33 of horizontal transfer unit 16.Afterwards, unite of chain 330 motions of transmission carriage assembly 12 by reverse unit 20.
In reverse unit 20, unite first lower roller 234 and the last roller 232 that transmits carriage 200 that transmits carriage assembly 12 and enter between first induction element 412,412 and second induction element 414,414.Continue to advance along with uniting transmission carriage assembly 12, first lower roller 234 and the last roller 232 that transmits carriage 200 kept by the sweep that first induction element 412,412 and first coils 374 or second dish 376.
Because the 4th chain pressing plate 242 that transmits carriage 206 discharges from progress path chain 330, and the 4th last roller 216 and the lower roller 218 that transmits carriage 206 discharges from guide rail 28a, and therefore first last roller 216 and the lower roller 218 that transmits carriage 200 is assemblied on the guide rail 28b.The same with the first transmission carriage 200, second to the 4th transmits carriage 202,204,206 successively with 376 motions of first dish, 374 or second dish.First transmits carriage 200 promotes by the 4th transmission carriage 206 that turns to, and motion when being guided by guide rail 28b.At last, the 4th last roller 216 and the lower roller 218 that transmits carriage 206 is assemblied on the guide rail 28b, and its chain pressing plate 242 extruding return path chains 332, unites the divertical motion that transmits carriage assembly 12 thus and finishes.
Unite and transmit carriage assembly 12 is transformed into horizontal transfer unit 16 from the return path chain 332 of reverse unit 120 endless chain 30.Subsequently, unite transmit carriage assembly 12 by the endless chain 30 of horizontal transfer unit 16 in Figure 12 the direction shown in the arrow B on guide rail 28, move.That is, unite transmit carriage assembly 12 by guide rail 28a guiding and in Figure 12 the direction shown in the arrow A move, turn to 180 ° by reverse unit 20 then, and by guide rail 28b guiding and move along the direction shown in the arrow B.
Because lower roller 234 and last roller 232 are columniform shape, therefore oppositely unit 20 allows first to the 4th transmission carriage 200,202,204,206 easily to turn to.
And, because have two lower rollers 234 and two to go up rollers 232, transmit that driving force ratio that carriage assembly 12 turns to has a lower roller 234 and a situation that goes up roller 232 is big so be used to make unite.If have three or more lower rollers 234 and the three or more individual roller 232 of going up, then three lower rollers and last roller 234,232 are difficult to enter at first guiding piece 412 and first and coil between 374 and second dish 376, turn to thereby make very difficult order unite transmission carriage assembly 12.
Therefore, two lower rollers 234 and two go up rollers 232 and allow to unite that to transmit carriage assembly 12 reliable and easily turn to.
Transmit carriage assembly 12 from guide rail 28a with progress path chain 330 discharges, turns to or during by guide rail 28b and return path chain 332 setting in motions, do not impact not to be applied to unite and transmit on the carriage assembly 12 when uniting.Particularly, transmit carriage assembly 12 by reverse unit 20 oppositely the time, unite and transmit carriage assembly 12 and can transfer to return path 332, and can not impacted from progress path chain 330 when uniting.Therefore, can prevent that connecting rod 1 from transmitting carriage assembly 12 and come off and be damaged from uniting.
Use description to below unite the operation of installing and removing on the transmission carriage assembly 12 as the connecting rod 1 of workpiece, and use this to unite and transmit the operation that carriage assembly 12 transmits connecting rods 1 at this.
Transmit carriage assembly 12 and move to when waiting to load bench board 26 places of connecting rod 1 when uniting, unite and transmit carriage assembly 12 and stop at given position by following stop motion mechnism 2010.
Afterwards, the bar 1026 of cylinder 1024 promotes.At this moment, because support rollers 1040 rolls in the mode than the inclined-plane 1030 of major diameter part 1028 that abuts against on bar 1026 upper ends, so support rollers 1040 moves at the radially inner side than major diameter part 1028.Hook 1038 tilts, and engages finger 1082 with the level of joint element 1074 up to final its upper end of stretching out and engages.At this moment, uniting transmission carriage assembly 12 is positioned.
First bar 1086 and second bar 1100 are by being promoted rising than major diameter part 1028 on bar 1026 upper ends.The end of arm 1098 is raised, thereby makes clip 1096a outward-dipping, and this end is contained in the recess 1090 in first bar 1086 of the first fixing device 1078a.Because the toothed portion that has of clip 1096a, 1096b keeps engagement each other, therefore when clip 1096a was outward-dipping, clip 1096b was also outward-dipping.As a result, as shown in figure 30, clip 1096a, 1096b open.
Be compressed at aforesaid operations process medi-spring 1092.
The end that is contained in the first L shaped arm 1128a in the recess 1104 in second bar 1100 is raised, thereby this first L shaped arm 1128a is rotated with respect to its crooked bight.Therefore, press rods 1114 is extruded and moves by the other end of the first L shaped arm 1128a, and the outer shifting board that engages with press rods 1114 at last moves along the direction away from second bar 1100.At this moment, because tooth 1117a, the 1117b of press rods 1114,1116 keep engagement with miniature gears 1118, as shown in figure 31, so press rods 1116 is mobile in the opposite direction along the side that moves with press rods 1114 by rack and pinion mechanism 1119.At this moment, the interior shifting board that engages with press rods 1116 moves towards second bar 1100.
That is, outer shifting board 1106 and interior shifting board 1108 move away from each other in by guide rod 1130a, 1130b guiding.Therefore the first holding device 1080a opens (seeing Figure 30).When outer shifting board 1106 and interior shifting board 1108 each intervals farthest the time, guide rod 1130a discharges from outer shifting board 1106, and guide rod 1130b discharges from interior shifting board 1108.
The second fixing device 1078b and the second holding device 1080b are with direction operation same as described above.Spring 1134 is therefore by two interior shifting board 1108,1108 compressions.
As shown in figure 26, be inserted into respectively the first holding device 1080a and the second holding device 1080b by two connecting rods 1 of predetermined transfer device (for example, robot etc.) clamping front side from them.Being inserted among the first groove 1076a or the second groove 1076b of each connecting rod 1 than minor diameter first end 3.
Afterwards, the bar 1026 of cylinder 1024 is reduced, thereby first bar 1086 and second bar 1100 are discharged under the pressure of cylinder 1024.Second bar 1100 descends, and spring 1092,1092 elongations.Spring 1092,1092 extruding first bar 1086,1086, thus first bar 1086,1086 is descended.
Because arm 1098 descends, therefore intermeshing have toothed portion that clip 1096a, the 1096b of the first fixing device 1078a are sloped inwardly.The shank 6 of connecting rod 1 is at this moment by clip 1096a, 1096b clamping.Because clip 1096a, 1096b be claw type, so their clamping connecting rods 1 reliably, and prevent that connecting rod 1 from coming off.The second fixing device 1078b is operation in the same way also.
The end of the first L shaped arm 1128a and the second L shaped arm 1128b is lowered, thereby the first L shaped arm 1128a and the second L shaped arm 1128b are rotated.Therefore, press rods 1114,1114 discharges from the pressure from the first L shaped arm 1128a and the second L shaped arm 1128b.When the pressure from the first L shaped arm 1128a and the second L shaped arm 1128b became elastic force less than spring 1134, spring 1134 elongations were with shifting board 1108,1108 in pushing. Interior shifting board 1108,1108 shifting board 1106,1106 outward moves, and this outer shifting board moves towards interior shifting board 1108,1108 by rack and pinion mechanism 1119.
Outer shifting board 1106,1106 and interior shifting board move towards each other for 1108,1108 this moments, up to final they from its opposite side keep connecting rod 1 than major diameter the second end 5.
Therefore, according to present embodiment, the first end 3 of each connecting rod 1 all inserts and remains among the first groove 1076a or the second groove 1076b, its shank 6 is by the first fixing device 1078a or second 1078b of the mechanism clamping, and its second end 5 is kept by the first holding device 1080a or the second holding device 1080b, thereby each connecting rod 1 all carries with erectility by uniting transmission carriage assembly 12.Because elongated connecting rod 1 transmits carriage assembly 12 with the erectility carrying by uniting, therefore can unite transmission carriage assembly 12 along its horizontal and vertical dwindling, therefore reduced in size.
The first fixing device 1078a and the second fixing device 1078b are opened and closed, thereby only by the cylinder in the bench board 26 1,024 the first holding device 1080a and the second holding device 1080b are kept and release link 1.Therefore, this is united transmission carriage assembly 12 and is not needed to be combined with hydraulic efficiency gear, pneumatics and electric device, thereby makes the designs simplification of uniting transmission carriage assembly 12 and transfer system 10.
Because connecting rod 1 transmits carriage assembly 12 carryings by uniting, so connecting rod 1 is not hit, and therefore can prevent that connecting rod is damaged.
In addition, because connecting rod 1 is supported by the first groove 1076a or the second groove 1076b, come off from uniting transmission bracket system 12 so prevented connecting rod 1 reliably.
When the bar 1026 that makes cylinder 1024 reduced, support rollers 1040 was rolled along the inclined-plane 1030 than major diameter part 1028 on bar 1026 upper ends, and radially outward moves than major diameter part 1028 with respect to this.At this moment, hook 1038 is owing to the extruding of spring 1044 is tilted.As a result, the outstanding upper end of hook 1038 engages finger 1082 disengagings (seeing Figure 15) from the level of joint element 1074.At this moment, uniting transmission carriage assembly 12 discharges from first lockout mechanism 1036.
In addition, uniting transmission carriage assembly 12 discharges from stop motion mechnism 2010.
During this period of time, motor 32,32b, 164,165 keep energising and do not stop.Therefore, unite transmission carriage assembly 12 in, begin once more to move by on-cycle endless chain 30 by guide rail 28 guiding from what stop motion mechnism 2010 discharged.Connecting rod 1 is sent to bench board 26, is used to carry out next process.
In next bench board 26, the connecting rod 1 that is transmitted removes by the transfer device clamping and from uniting transmission carriage assembly 12.At this moment and since connecting rod 1 with the second end 5 as the upper end and upright, so transfer device clamping connecting rod 1 easily.
Because connecting rod 1 is by the first groove 1076a and second groove 1076b location, therefore transfer device is operated in an identical manner in continuous mutually circulation.Even transfer device is simple in structure, it also can shift connecting rod 1.Therefore, transfer device does not need complicated structure, and therefore can reduce equipment investment.
In order to transmit the connecting rod 1 with different size, clip 1096a, 1096b, outer shifting board 1106,1106 and interior shifting board 1108,1108 move, with from its opposed end clamping or keep connecting rod 1.Therefore, unite transmission carriage assembly 12 and can carry connecting rod 1 with different size.Therefore, unite transmission carriage assembly 12 and needn't revise its size and dimension according to the connecting rod 1 that is carried.
To carrying out tapping to form screw thread thereon or to carry out other processing from uniting the connecting rod 1 that transmits carriage assembly 12 releases.Afterwards, by uniting transmission carriage assembly 12 connecting rod 1 is sent to bench board 26, to carry out subsequent processing, in this operation, connecting rod 1 is processed to final products.
In the present embodiment, the connecting rod 1 with same size illustrates as workpiece.Yet, can transmit connecting rod 1 with different size.Be used to keep the outer shifting board 1106 and the interior shifting board 1108 of fixing device of the workpiece of reduced size under the pressure of spring 1134, to close, and clip 1096a, the 1096b of holding device close under the pressure of spring 1092.The outer shifting board 1106 of the first fixing device 1078a and the second fixing device 1078b is in different off positions with clip 1096a, the 1096b of interior shifting board 1108 and the first holding device 1080a and the second holding device 1080b.
Needn't be combined with fixing device and holding device simultaneously, and can in conjunction with in these fixing devices and the holding device one of at least.
Each the first holding device 1080a and the second holding device 1080b are made up of outer shifting board 1106 and interior shifting board 1108.Yet one in these shifting boards can be replaced by adapter plate.
The workpiece that is transmitted is not limited to connecting rod 1.
To describe below when uniting and transmit carriage assembly 12 and make by guide rail 28b guiding and will arrive bench board 26 time, by stop motion mechnism 2010 and unite the operation that transmits carriage assembly 12 decelerations and stop.
In description subsequently, uniting of supposing that the direction shown in the arrow A is advanced in Fig. 2 transmits carriage assembly 12, by reverse unit 20 oppositely when the direction shown in the arrow B is advanced, to stop by stop motion mechnism 2010.
As mentioned above, the ingress path 2110 of stop motion mechnism 2010 has narrower part 2126 and wider portion 2128.When first transmitted carriage 200 near bench board 26, last roller 232 entered narrower part 2126.
The width of narrower part 2126 diminishes (seeing Figure 35) gradually along uniting the direct of travel that transmits carriage assembly 12 (direction shown in the arrow B in Fig. 2).Therefore, the circumferential side wall of last roller 232 is being held against the shank of the first arm 2100 and second arm 2102.Transmit carriage assembly 12 by less relatively power support owing to unite, therefore unite transmission carriage assembly 12 and be decelerated.
As shown in figure 36, continue to advance along with uniting transmission carriage assembly 12, leading last roller 232 launches narrower part 2104.That is, last roller 232 extends the piston rod 2142 of spring 2104 and cylinder 2106, thereby is allowed to through narrower part 2126.
At this moment, unite the kinetic energy that transmits carriage assembly 12 and change into the merit that is used to make spring 2104 and piston rod 2142 extensions by the leading roller 232 of going up.Therefore, reduced and united the kinetic energy that transmits carriage assembly 12, transmitted carriage assembly 12 and further slow down thereby make to unite.
Then, the trailed roller 232 of going up also makes the piston rod 2142 of spring 2140 and cylinder 2106 extend, so that narrower part 2126 is launched.Further reduced because unite the kinetic energy that transmits carriage assembly 12, united the speed that transmits carriage assembly 12 so further reduced.
The last roller 232,232 that transmits carriage assembly 12 of uniting that slows down enters wider portion 2128.The leading roller 232 of going up is supported by the support portion 2130 of the first arm 2100 and second arm 2102, transmits carriage assembly 12 and stops fully so make to unite.
Particularly, go up roller 232,232 for two and launch the first arms 2100 and second arm 2102, unite the kinetic energy that transmits carriage assembly 12 thereby absorb step by step with separated from one another.Owing to unite and transmit carriage assembly 12 and slow down gradually and stop, therefore can prevent to produce impact when carriage assembly 12 stops when uniting to transmit.Therefore, prevented to come off or damage by uniting the connecting rod 1 that transmits carriage assembly 12 carryings.
Enter ingress path 2110 up to uniting when transmitting carriage assembly 12 and stopping at last roller 232, last roller 232 in rotation with the first arm 2100 and second arm, 2102 maintenance rolling touch.With compare with simple non-rotary drum forms, last roller 232 is not easy to be worn.Therefore, uniting transmission carriage assembly 12 can slow down in long period of time and stop reliably.
If motor 32,32b, 164,165 unite the speed that transmits carriage assembly 12 to quicken rotation with increase, then spring 2104 can be designed to have the elasticity (harder) of enhancing, perhaps cylinder 2106 can be designed in bigger power piston operated 2104, thereby it is slowed down reliably and stops according to uniting the speed that transmits carriage assembly 12.
Therefore, stop motion mechnism 2010 can easily make to unite and transmit carriage assembly 12 and slow down and stop.Therefore, do not cause and apply unsuitable restriction uniting the transmission scope that transmits carriage assembly 12.
When uniting when transmitting carriage assembly 12 and stopping, first transmits carriage 200 by second blocking device, 2108 location and fix (seeing Figure 34).Particularly, activated cylinders 2105 tilts with respect to its connecting portion as pivot thereby make hook 2152 transmit carriage 200 towards first with withdrawal piston 2156.
At last, the hook end of hook 2152 abuts against the end face of the stop part 238 of the first transmission carriage 200, as shown in figure 37.At this moment, the first transmission carriage 200 is supported, transmits carriage assembly 12 location and fixing thereby make to unite.
As mentioned above, first lockout mechanism 1036 (seeing Figure 33) activated, so that joint element 1074 engage hook 1038 (seeing Figure 22 and 26).Therefore, make to unite and transmit carriage assembly 12 and locate more reliably.
Afterwards, activated cylinders 1024 to be closing clip 1096a, 1096b, and activates rack and pinion mechanism once more so that outer shifting board 1106 and interior shifting board 1108 move towards one another.The new connecting rod 1 that is in erectility is by uniting the first fixing device 1078a, the second fixing device 1078b, the first holding device 2062a and the second holding device 2062b clamping that transmits carriage assembly 12.The lower end of connecting rod 1 is supported by the first groove 1076a and the second groove 1076b respectively.
When aforesaid operations was finished, the piston rod 2156 (seeing Figure 34) of cylinder 2150 stretched out, and tilted so that hook 2152 transmits carriage 200 away from first.At this moment, first transmit carriage 200 from 2108 releases of second blocking device.
Then, activated cylinders 2106 is stretching out piston rod 2142, thus extrusion piston bar supporting member 2144.As a result, the first arm 2100 and second arm 2102 move away from each other, thereby make the diameter of the width of ingress path 2110 greater than last roller 232.At this moment, uniting transmission carriage assembly 12 discharges from stop motion mechnism 2010.
During this period, motor 32 continues rotation, that is, endless chain 30 continues cycling and do not stop.Therefore, the transmission carriage assembly 12 of uniting that discharges from stop motion mechnism 2010 begins to advance immediately once more.
Therefore, unite and transmit carriage assembly 12 and can under situation about not stopping, stopping as motor 32 that promotes to unite the drive source that transmits carriage assembly 12 and endless chain 30.Therefore, can promptly move once more owing to transmit carriage assembly 12, so it can transmit connecting rod 1 efficiently from uniting of stop motion mechnism 2010 releases.
When the last the 4th transmits carriage 206 from ingress path 2110 releases, piston rod 2142 withdrawals of cylinder 2106.Afterwards, the first arm 2100 and second arm 2102 (seeing Figure 35) move towards each other with respect to bolt 2118a, 2118b under the pressure of spring 2104.At this moment, the end face of the head of backstop bolt 2138 abuts against the second stop part cartridge by diffusion of volatile treating agent 2136, to form second ingress path 2110 with predetermined space between them.
Unite transmit carriage assembly 12 in by guide rail 28b guiding in Fig. 2 the setting in motion once more of the direction shown in the arrow B, unite and transmit carriage assembly 12 and in next bench board 26, slow down in the same manner as described above and stop, being used to shift connecting rod 1.
In the above-described embodiments, oppositely 180 ° of direction changes that transmit carriage assembly 12 will be united in unit 20.Yet oppositely 90 ° of going direction changings that transmit carriage assembly 12 can will be united in unit 20.According to this modification, if adopt one to go up roller 232 and a lower roller 234, change of direction easily then.
