The specific embodiment

As disclosed among the top figure, devices for taking-up (is seen Fig. 1-1A, 2-2A) comprise separating of piece-rate system or known type with flying shearing machine, this is separated to wire rod on two lines with 1 piece-rate system of representing or flying shearing machine, suitable wire guide device 3 by known type, perhaps wire rod on the line or on another line 2 respectively towards two adjacent coiling machines 4 any and go, thereby coil B.

When in a coiling machine, forming coiled material, in adjacent coiling machine, stop, with conveyer 5 ..., 521 pick up the coiled material of finishing.

The coiled material conveyer (5, Fig. 1,1A, 2,2A, 3A, 3B, 3C)

The coiled material conveyer 5 of Figure 1A, ..., the 521st, a type, promptly have post 51, and have a flag-shaped arm 52 of rotation, arm 52 ends have openable clamping device, this clamping device has a pair of clamp or laterally relative pawl pincers 522, be used for from corresponding devices for taking-up 4, pick up and axially take out coiled material B in the coiling machine 4 of 4A, described coiled material (Fig. 2) is sent to the bundling of back or ties up the position from the coiling machine that has stopped, the baler or the binder 6 of the already known processes of two positioned opposite by Fig. 2 A carry out bundling, then coiled material are sent to each and lash coiled material B1 depository.

Therefore the munnion conveyer be a door type, thereby and its turning arm 52 can raise and reduces and pick up and the sedimentation action by dynamic fluid piston 520, pass through motor/variable speed driver 510 its rotations of assurance accordingly on the corresponding thrust block seat in column bottom simultaneously.

By having in pairs the telescopic guider (box guide) 520 of deflector roll 5201 relatively, deflector roll is worked in the mode of sliding on the post in double T cross section, guarantees the rise and the reduction of arm 52.

By having the clamping device of four clamps, clamp automatic centering on coiled material B, and clamp is by being used to accordingly to unclamp and closed fluid operating cylinder unclamps and closed, thus be easy to pick up coiled material.

Be appreciated that in this way translatory movement very fast and can open work, it can not hinder or hinder the peripheral region, so can also make that whole device is compacter.In addition, this class moves obviously very simple and very stable, and maintenance cost is reduced to minimum.

Batch group (4,4A, 4B, 4C, Fig. 4,4A, 5,6,6A)

Two are batched group is identical and adjacent, has wire rod and batches reel F, and it has openable reel AV and has vertical axis.

Also include except the reel core tube AV-41 of center in each group, form is two relative coiled material hold down gag 4B of paired roller 422, and two wire-guide jaws pincers of introducing automatically, is used for making the wire rod automatic guide at first batching 4C.

The center is to have the reel 41 that can open volume coring tube AV.

Relative coiled material hold down gag 4B

They comprise two corresponding articulated devices 42, these two articulated devices 42 with respect to the wire rod of the suitable reel AB of side direction before inlet wire be placed on the both sides of volume coring tube AV.

Described roller is installed on the articulated arm 421 that is hinged to polycrystalline substance 420, and described roller is from rotating to the position that leans with coiled material B Fig. 6 away from position (Fig. 4).Producing this moves by the fluid-operated bottom cylinder 4212 on the reaction arm 4210 and finishes.

Described roller 422 (seeing Fig. 6 A) is mounted in pairs in the parallelogram movable joint mechanism 4222, and in pairs relative arm is installed on the roller bearing 4220 and under the pressure effect of corresponding dynamic fluid cylinder device 4221 resilient movement takes place.

Moving like this is simple and stable, and guarantees the constant location of roller, thereby suitably controls the end turns of coiled material B among the volume coring tube 4V-41, and be lax before avoiding picking up.

Wire guide group 4C

The wire guide group comprises that the relative wire rod of two semicircles enters guide grab pincers 431, guide grab pincers 431 flatly 430 are hinged on the side, and be hinged on dynamic fluid cylinder 4311 controls of fast moving of pawl pincers transfer arm 4310 ends of machine bottom 4301 by side direction, leave and close thereby be rotated by the reaction arm 43101 that fluid-operated bottom cylinder 43102 is operated.

Be appreciated that like this, although make wire rod enter that guide grab pincers 431 leave and close by relative bottom cylinder 43102, but the final of them moves, just accurately and apace engage and remove joint with wire rod, be rely on independently, short, control device 4311 and realizing accurately and rapidly, if with having the close of big stroke and leaving mobile device 43102, cannot realize that then the final of above-mentioned performance moves.

Therefore above-mentioned can the acquisition at a high speed and good effect can not tangled, or do not needed to reduce the pace of wire rod, or do not need operating speed to regulate kink.

In Fig. 5, can be clear that brief joint and remove the motion that engages.

Batch central. set-batch reel (4A, Fig. 7,7A, 7B, 8)

It comprises that have can be closed and the central coiling reel 41 of openable reel core tube AV, the open and close action of reel core tube AV:

In case after coiled material B finishes it is taken out the open and close of necessary reel core tube AV, be to produce by four rotation petal flange (petal flange) parts 411, inner link movable joint mechanism 4111 relies on sleeve 413 and moves, and sleeve moves axially by means of the dynamic fluid cylinder 4131-4132 by 4133 work of dynamic fluid loop, and described loop is transported to reel bottom 41330 on the non-rotating common axle with respect to rotating drum core tube AV.

The advantage of this scheme is guaranteed the compactness of rotating and is simplified very important for connect 4131 by the rod end with respect to sleeve 413.

Reel core tube AV profile variation

Reel core tube AV is made up of four parts, i.e. four pliers 410, and they are hinged on the bottom 4121 of the lower mandrel member flange 412 of shelving coiled material.

At an upper portion thereof, the moveable part of reel core tube 410 hinged 4112 is on described axially-displaceable moving sleeve 413.

Like this, when displaceable sleeve 413 rose, upper flange petal 411 was opened, thereby promptly can form coiled material B with the spool shaft quadrature in coiling process, and reel core tube part 410 is parallel and forms cylindrical drum (Fig. 7).

When coiled material is finished, in order to be easy to take out, removable inner sleeve 413 withdrawal downwards operation simultaneously:

The upper flange petal of-reel is upwards closed as flower,

A taper shape is determined in-410 (Fig. 7 A) reenter on top core, and the size of its upper bottom portion is less than lower bottom part.

So just can and be easy to take out coiled material B by the pawl pincers of clamping device 522.

Cooling system

The reel core tube part or the pliers 410 of semicircle form passage 4102 in inner perforated.This passage is by the tube connector 41020 two

coaxial channels

41021,41022 of inner tube of ining succession.

Guaranteed the cooling of reel like this.

In addition, the profile of described core or pliers forms waveform by vertical counterbore 4101 alternately.

The minimizing that contacts of reel core tube AV surface and coiled material B is easy to make air to pass these vertical counterbores and circulates like this.

Connect bevel type gear driver 40 by already known processes, the mechanization of 401-402 makes reel core tube AV rotate with respect to spigot shaft coaxle.

The cycle period that batches

Beginning of coiling is to link to each other with wire rod drawing-in system AB by described movably semicircle pawl clamp device 431 relatively, with first linkage to the flange of the side of coiling machine or bottom reel core tube AV.

When wire rod F fits snugly on the reel core tube AV, and after first circle began, this device received wire rod F from distributor 2-3, and the zone that forms coiled material must promptly be available.In order to accomplish with effective and efficient manner, used rapid displacement fast moving (short distance rotation 4310, Fig. 5).

Subsequently, than slow and stroke rotation device 4310-43102 far away the wire-guide jaws pincers are left, space empty is come out, thereby make that the last coiled material circle 422 of described control roll can be close with other.

When coiled material stopped, last circle remains closed up to the clamping device 522 of conveyer 5 intervened like this, and four pawl pincers of clamping device 522 rotate 45 ° with the coiled material B between the described roller 422 of clamping.

Roller 422 is removed subsequently, and coiled material B still remains closed by clamping device.It is fastening and closed that thereby while reel core tube AV also opens the upper flange petal that will upwards locate.

Like this, the coiled material inside that stops also can be loose, thereby and rely on arm 52 liftings of munnion conveyer 5 upwards to shift out easily, and rotate backward with sedimentation in the baler that has two relative bundling groups 6.

At this moment will repeat this circulation, initial wire-guide jaws pincers be turned back to the position adjacent with reel core tube AV, to receive the new wire rod F (Fig. 4) that will batch.
