Again, above-mentioned cutting table 6 is accepted being set up in parallel that conveyer belt 4 does can transmit each other, carry with above-mentioned, can cut off tubular body W in the above.In this example, the upstream side of cutting table 6 is that the axle fulcrum J that is arranged on the above-mentioned pallet 11 does the axle supporting.As shown in Figure 1, the upstream side of cutting table 6 ground that can freely fascinate slopes down to film trasport position X2 from the normal position X1 of level towards the downstream.This work that fascinates is by the connecting rod action of the advance and retreat parts 19 of the cylinder in for example foot that is installed on the above-mentioned pallet 11 etc. and finish.
At outgoing position X2, above-mentioned cutting table is connected to and discharges (not the illustrating) such as discharge conveyer belts that roller is used by the groove 20 of same inclination.In addition, at above-mentioned normal position X1, it is freely to be supported on the supporting arrangement 22 that the downstream side of cutting table 6 can take off.The supporting 21 that described supporting arrangement 22 has along its length, and F moves freely, advance and retreat.
As shown in Figure 3, this supporting arrangement 22 have the cylinder that is installed on the above-mentioned pallet 11 etc. advance and retreat parts 23, be subjected to the above-mentioned supporting 21 of connecting-rod head 23A supporting.Supporting 21 comprises a pair of seat sheet 21A, described seat sheet 21A has the bearing plane of accepting below the side of above-mentioned cutting table downstream, and make one by connector 24 with above-mentioned connecting-rod head 23A and install, simultaneously, be directed to length direction F by the guide roller 25 of for example コ word shape.
Then, above-mentioned guiding device 5 is accepted and is stated from the above-mentioned tubular body W that accepts on the conveyer belt 4 accepting position Y1, and it is guided to off-position Y2 on the above-mentioned cutting table 6.As shown in Figure 4, but guiding device 5 have the above-mentioned tubular body W of clutch clamping freely downstream side We (also being front end We) anchor clamps 27 and make these anchor clamps 27 anchor clamps moving-member 29 of moving of F along its length.
The mobile device 39 that above-mentioned anchor clamps moving-member 29 comprises travelling carriage 37 and travelling carriage 37 is moved.Described travelling carriage 37 can do to move configuration freely on the track 36 that F stretches along its length.By cramp bar 40 above-mentioned anchor clamps 27 are housed on above-mentioned travelling carriage 37, again, above-mentioned track 36 is by above-mentioned pallet 11 supportings.
In this example, as above-mentioned mobile device 39, be that given an example 2 advance and retreat parts 39A, 39B with cylinder etc. make situations about being connected in series, at this moment, the advance and retreat parts 39A with a side is fixed on the pallet 11 respectively, other sides' advance and retreat parts 39B is fixed on the above-mentioned travelling carriage 37.
Therefore, by dwindling of both sides' advance and retreat parts 39A, 39B, the centre position Z2 that above-mentioned travelling carriage is 37 removable, can stop to move to freely the position Z1 that is positioned at upstream side, only form because of the stretching of a side advance and retreat tool 39A, and can be removable by the stretching, extension of both sides' advance and retreat tool 39A, 39B, stop to move to freely three positions of position Z3 that are positioned at downstream, i.e. Z1～Z3.So at the position Z1 of upstream side, above-mentioned anchor clamps 27 are removed on the above-mentioned centre position Z2 of off-position and are clamped at front end We in the front end We of the above-mentioned tubular body W that accepts position Y1 of clamping.In addition, after the releasing, anchor clamps 27 retreat to the position Z3 in above-mentioned downstream, and standby is to the tubular body W that accepts next time.
Show slightly that as Fig. 5 anchor clamps 27 have a pair of insertion sheet 30 and the insertion sheet holding device 31 that inserts in the tubular body W front end We.Described insertion sheet holding device 31 by this, can be done flat press-stretched, clamping with the front end W of tubular body W because each inserts sheet 30 can sow discord mobilely in the left and right sides.In this example, by above-mentioned insertion sheet 30 is made semi-cylindrical, and it is closely connect mutually, the path that can make the above-mentioned tubular body W of easy insertion is cylindric.
In addition, in this example as shown in Figure 6, as above-mentioned insertion sheet holding device 31, be exemplified by can before and after the key 32 and a pair of slidably horizontal example that constituted of moving sheet 33 of advance and retreat.Described a pair of slidably horizontal moving sheet 33 has the inclined-plane 33S that can engage with the wedge surface 32S of key 32, and can be slided in both sides by seesawing of this key 32.Symbol 34 among the figure is that each horizontal moving sheet 33 is pressed to inboard spring.In addition, symbol 35 is to drive key 32, for example the connecting rod of the advance and retreat parts of cylinder etc.Can adopt cam to make it the mechanism that laterally moves as inserting sheet holding device 32, and adopt well-known various mechanism such as using rack-and-pinion again.
Secondly, shown in Fig. 7～9, in this example, said fixing device 7 is provided with the pressing element 43 of pectination, to be vertical on, scaffold 41 across the door type of above-mentioned cutting table 6 with above-mentioned length direction F, the pressing element 43 of described pectination can be made free lifting by Lift Part 42.And,, be fixed on the cutting table 6 because the decline of pressing element 43 can be pressed into flat with the above-mentioned tubular body W that is directed, is positioned at off-position Y2.
Above-mentioned supporting frame 41 is by upright body side frame 41a, the 41b that is located on the pallet 11, and the upper frame 41c that connects between the upper end constitutes.On a side body side frame 41a, be fixed with described Lift Part 42 by installing plate 44.
In this example, illustration said fixing device 7 by the 1st fixture 7A and and the occasion that constituted of the 2nd fixture 7B.Described the 1st fixture 7A possesses fixedly the 1st pressing element 43A of the cut-out tubular body W in half zone of upstream side; Described the 2nd fixture 7B has fixed the cut-out tubular body W in half zone, downstream when having above-mentioned the 1st pressing element 43A side by side.
1st, the structure of the 2nd fixture 7A, 7B is roughly the same.This device is equipped with the 1st, the 2nd pressing element 43A, 43B in the lower end of the connecting rod 42a of the Lift Part 42 that is subjected to 44 supportings of above-mentioned installing plate respectively.And as above-mentioned Lift Part 42, in this example illustration use the situation of the cylinder of the built-in axis of guide 45.
In addition, above-mentioned each pressing element 43A, 43B be by the principal part 46 of the heavy wall that is fixed on above-mentioned connecting rod 42a lower end and from principal part 46 and above-mentioned length direction meet at right angles arrange pull into microscler a plurality of last items 47 formed pectinate textures.Simultaneously, as the comb eye of the clearance G of 47,47 of above-mentioned last items, comply with the width of formed ring bodies W1 and form corresponding intervals.
Here, why constitute said fixing device 7 by the 1st, the 2nd fixture 7A, 7B, this is when preventing fixed tubular body W, the out of supply and occurrence positions skew of the tubular body W that is directed.That is, shown in Figure 11 (C)-Figure 12 (B),, under its front end We still is in by the state of anchor clamps 27 clampings, allow the pressing element 43A of the 1st fixture 7A descend to being directed to the tubular body W of off-position Y2.By this, half zone of upstream side in the zone of feasible cut-out tubular body W tightens at cutting table 6 and is pressed into flat, and is fixing.Then, under this stationary state, retreat to position of readiness Z3 from 27 disconnections of front end We jig, the pressing element 43B of the 2nd fixture 7B descends and closes, and fixes the remainder (half zone, downstream) that cuts off in the zone.
Like this, by pressing of two-stage, can there be the whole zone that skew ground, position high accuracy fixed tubular body W need cut off.At this moment, above-mentioned jig 27 also has the function to the center.In addition, the control air of decline side was pressed when for example available accurate pressure-reducing valve was regulated Lift Part 42 actions, can control the thrust of fixture 7 thus.In this example, shown in Fig. 8,9, the inner chamber of tubular body W is crushed, and inner circumferential surface is in contact with one another, and this tubular body W is subjected to the extruding of flattening power, is squeezed into band shape.
In addition, because the extruding of flattening, can be in the past like that, limit revolution tubular body W limit cuts off, and can prevent 2 layers of vestige that cuts thus.Have again, concerning cutter blades 4, can its sword of attenuate be thick significantly when crossing cutter, can prevent to have the cutter blades 49 of the section of guillotine type cutting machine, carry out high-precision cut-out.
In addition, because above-mentioned pressing element 43 is pectination, therefore uses a plurality of cutter blades 49 and near each cutter blades 49, push down tightly and can once cut off tubular body W.That is, when can state the high accuracy cut-out in realization, reach the high efficiency of cut-out.
Secondly, shown in Fig. 7-10, width is every putting in accordance with regulations with above-mentioned cutter blades 49, because cutter blades 49 is by above-mentioned each clearance G, tubular body W is cut off into a plurality of ring bodies W1.
Specifically: above-mentioned shearing device 9 have with above-mentioned cutter blades 49 in accordance with regulations width every the cut-out parts of putting 50, can support the Lift Part that cuts off parts 50 free liftings and draw and allow this Lift Part draw the moving-member 52 that becomes vertical direction to move with above-mentioned length direction F.
In this example, moving-member 52 by the guide rail 53 of the upper frame 41c of the above-mentioned scaffold 41 that is laid in, combine with guide rail 53, with the vertically removable travelling carriage 54 that is directed freely moving of above-mentioned length direction F, and constituted with the advance and retreat parts 55 that flange is stuck in above-mentioned upper frame 41c goes up, its connecting-rod head is connected in above-mentioned travelling carriage 54 cylinder etc.
In addition, in this example, the cylinder that above-mentioned Lift Part draws by built-in guide shaft 56 constitutes, and its connecting rod 51A is supported on described travelling carriage 54 down.
In addition, shown in Figure 10 enlarged, above-mentioned cut-out parts 50 comprised: be installed in the supporting member 57 as コ word shape of above-mentioned connecting rod 51A lower end, at the bolster 59 of supporting member 57 upper supports, can freely load and unload and can the rotating a plurality of above-mentioned cutter blades 49 that is supported on the bolster of freedom.
At this moment, because above-mentioned change, the position that is positioned at the cutter blades 49E of upstream side changes.Therefore, in this example, the length of dwindling of the connecting rod of an above-mentioned side's advance and retreat parts 39A (shown in Fig. 4 (A)) can be with adjustings such as blocks.And, because this dwindles the adjusting of length, above-mentioned position of accepting position Y1 and the described cutter blades 49E of upstream side is coincided.
Like this, in this routine shearing device 9, shown in Fig. 8,9, cut off parts 50 above cutting table, the while is in the normal position U1 standby of the outer side that is positioned at pressing element 43 (left of figure).And tubular body W is when the device 7 that is fixed is squeezed into flat, cuts off start that parts 50 draw because of Lift Part and drops to the down position U1A that cutter blades 49 and cutting table 6 contact above.Thereafter, moving-member 52 action, above-mentioned cutter blades 49 turns to the transversal position U1B of crosscut tubular body W by clearance G, by this, cuts off above-mentioned tubular body W.For this reason, in this example, the length of above-mentioned last item 47, be clearance G length L 1 setting greater than with above-mentioned tubular body W crushing to the flat flat width L2 and the diameter L3 sum of above-mentioned cutter blades 49, that is, and greater than L2+L3.
Secondly, with reference at Figure 11,12, with regard to the molar behavior concept nature schematic illustration of the cutting machine 100 of this example.
At first, the anchor clamps 27 of guiding device 5 move to the position Z1 of upstream side from position of readiness Z3, and clamping is supported in the tubular body W front end We that accepts position Y1, simultaneously, gets back to centre position Z2 under clamp position, stops (Figure 11 (A)-(C)).That is, will be positioned at the tubular body W that accepts position Y1 and guide to off-position Y2.
In addition, under the state of anchor clamps 27 clamping front end We, allow the pressing element 43A of the 1st fixture 7A descend, half the regional tubular body of upstream side that cuts off in the zone is pressed to flat, fixing.Then, anchor clamps 27 are decontroled front end We and are retreated to holding state Z3, and the pressing element 43B of the 2nd fixture 7B descends, and half the regional tubular body that cuts off in the remaining downstream area in zone are pressed to flat fixing (shown in Figure 11 (C)～Figure 12 (B)).By this, make the not occurrence positions skew of whole zone of cut tubular body, can do good the fixing of precision.
Under this stationary state, when the cut-out parts 50 of shearing device 9 drop to U1A from holding state U1, under this decline state, cutter blades 49 turns to cross-section position U1B by clearance G, case is laterally moved by this, and above-mentioned tubular body W width in accordance with regulations is cut into a plurality of ring bodies W1 (Figure 12 (B), (C)).
So, fascinating to outgoing position X2 around axle fulcrum J by revolution cutting table 6, cut ring bodies W1 is discharged from outside device (Figure 12 (D)) by chute 20 (as shown in Figure 1).
The 2nd embodiment of said fixing device 7 is shown in Figure 13,14.In the 2nd embodiment, fixture 7 has the pressing element 43 of a long size and makes the Lift Part 70 of pressing element 43 liftings, and described pressing element 43 is used for fixing the whole zone that cuts off tubular body W.Thereby shown in Figure 14 (A)～(D), Lift Part 70 moves to the 1st down position P1 and the 2nd down position P2 with pressing element 43 under the state of above-mentioned anchor clamps 27 clamping tubular body W.Described the 1st down position P1 system cuts off the zone with the need of described tubular body W and is depressed on the cutting table 6, carries out temporary fixed down position; Described the 2nd down position P2 ties up under the above-mentioned temporary fixed state, described jig discharges tubular body W and moves to after the above-mentioned position of readiness, the whole zone that the need of above-mentioned temporary fixed tubular body W are cut off is depressed on cutting table 6 fixing position once more as flat.
Concrete is, above-mentioned Lift Part 70 slightly shows as Figure 13 (A), (B), comprise conduct be used for the main Lift Part 71 of the cylinder of the above-mentioned pressing element 43 of lifting, as the secondary Lift Part 72,73 of the cylinder of limiting rod stroke.In this example, above-mentioned installing plate 44 has supported major- minor Lift Part 71,72.
In this example, above-mentioned main Lift Part is equipped with above-mentioned pressing element 43 to being the cylinder of built-in guide shaft 71A in each lower end of connecting rod 71a and guide shaft 71A.In addition, the above-mentioned master's of above-mentioned guide shaft 71A break-through Lift Part cutter projection upward extends, and forms the abutting part 74 that connects with block 73 in the upper end.In this example, with above-mentioned upper end between the binding sheet that is connected constitute abutting part 74.
In addition, above-mentioned secondary Lift Part 72 is erected on the block 74 by having the guide shaft 71A that passes through hole in the upper end of connecting rod 72a.
Therefore, because the elongation of connecting rod 72a, above-mentioned secondary Lift Part 72 can make the lifting position Q2 of block 73 above following position of readiness Q1 moves to.
In addition, because the elongation of connecting rod 71a, above-mentioned main Lift Part descends from the position of readiness R of top to making pressing element 43.At this moment, above-mentioned block 73 is when lifting position Q2, and above-mentioned abutting part 74 connects with block 73, has restrained the elongation of connecting rod 71a, and pressing element 43 stops at the 1st the down position P1 place of temporary fixed tubular body W.
In addition, the connecting rod 72a of above-mentioned secondary Lift Part 72 dwindles, and when block 73 dropped to following position of readiness Q1, block 73 was disengaged to the contained of abutting part 74, and pressing element 43 can drop to the 2nd the down position P2 of fixed tubular body W.
Herein, so-called " temporary fixed " means and pushes down tubular body W lightly, the state that it can't be moved.For this reason, in this example, between above-mentioned block 73 and abutting part 74, spacer ring is can load and unload freely to install, and regulates the 1st down position P1.Above-mentioned cage ring 75 shown in Figure 15 (A), comprises the U word shape hole 75A of portion that can insert above-mentioned guide shaft 71A from the side, therefore, can easily replace.Fixing of cage ring 75, except can for example being adsorbed on the block 73 with magnet, also can be as this example, the bulb stopper 76 that setting can freely be haunted.In addition, as Figure 15 (B), cage ring 75 may be partitioned into two.
So, owing to stop at the 1st down position P1, therefore can be when the anchor clamps 27 of avoiding and being in clamp position disturb, identical with the fixture of above-mentioned the 1st embodiment that is made of above-mentioned the 1st, the 2nd fixture 7A, 7B, it is high-precision fixing to make non-migration ground to the whole zone of tubular body W.In addition, the pressure in the time of fixedly is also identical with the 1st embodiment, and its pressure preferably can be crushed to the internal organ of tubular body W the pressure of banded flat.For this reason, can control the control air pressure of the decline side of main Lift Part cutter with accurate pressure-reducing valve.
In above-mentioned the 1st embodiment, boundary vicinity between the 1st, the 2nd pressing element 43A, 43B is easily had an effect in the stress of tubular body W, and described stress can be in the 2nd embodiment, prevented by described fixture 7, thus, can suppress to result from the distortion of the section that this stress produces, improve aspect the quality very desirable.
More than, desirable especially example of the present invention has been described in detail in detail, but the present invention is not illustrated the qualification of example, but can be implemented the form of multiple variation.
