Description

The batch up gear that the binding material that has cut off is taken away

Technical field

The present invention relates to the batch up gear that a kind of binding material, especially metal tape that is suitable for having cut off taken away from the packing part.

Background technology

This device for example is used in the paper industry.The raw MAT'L of papermaking, be that paper pulp or waste paper usually come feed to tighten the mode that becomes to compress bundle by binding material (especially wire rod or band).After this raw MAT'L being placed before a kind of solvent is processed into aqueous suspension, such wire rod or band must be taken off usually.Though this can realize by hand that this is dangerous and bothersome.Therefore this class device has been done further improvement and development, the wire rod and the band that take off cut-out by this type of device can carry out automatically smoothly, for the adoptable batch up gear of this purpose is for example disclosed by German patent specification DE 2,821 336 C2.

Winding head of the present invention is being applied in tearing open in bundles and puts when middle, batch up gear is preferred to be arranged like this, makes it can be clamped in that relative with shutoff device on this packing part side.With band or wire rod before or after this opposite side cuts off, perhaps allow supporting face toward the packing part or allow the packing part advance like this facing to supporting, make the distolateral working end of supporting directly to lean against on the binding material to be removed.When after this this supporting rotates, coiling band or wire rod, thereby band or wire rod on the part of will packing take away, form volume less, more firm, that be collected and transport easily thus.

Supporting preferably places on the axle of motor, especially slow output speed electrical motor.But can for example be HM Hydraulic Motor also, this motor is preferred to be constituted like this, and it can be regulated as follows: it occupies a position of determining with respect to binding material to be accepted when stopping.The advantage of bringing like this is, this binding material can be more reliably and is accommodated in easily in the fluting on the supporting.

For the bale packing that becomes to be convenient to transport is tightened in pressing, the round steel wire of application examples such as 4mm diameter under many circumstances.This permission comes wound skein product with known batch up gear, is wound into so-called volume, and it is taken off from supporting vertically.Yet use under the situation of steel band as binding material at other, thereby may run into the situation that binding material is stuck and can not reliably it be taken off in batch up gear.Such steel band for example has 2mm thickness, and is made by steel, special steel or other elastomeric materials.This steel band is behind the coiling, promptly when having cancelled the moment of torsion that is applied by supporting for coiling, and loose opening promptly swelled in very easy strong resilience once more.This can cause: this binding material outwards expands after unloading so doughtily, thereby is stuck in batch up gear.

In other situations, binding material is not by metal but be made of plastics.Such binding material utilizes as band (for example width between 10 to 20mm, thickness is about the band of 1mm) in most applications.Plastic strap for example can be braiding or make by extrusion press.The binding material that is made of plastics may also can tend to unclamp once more the degree that bundle is torn in obstruction open behind coiling.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of new batch up gear, utilizes this device not only those can be used to bind the wire rod of packing part but also the band that those can be used to bind the packing part is reeled reliably and taken off from batch up gear again.Also insoluble plastic strap should be taken off according to certain particular design.

The batch up gear that above-mentioned technical matters is taken away from the packing part by a kind of binding material, especially metal tape that is suitable for having cut off solves, and this batch up gear is used for the guide of binding material, a supporting and the binding material that will reel by at least one and forms from the device that this supporting is pushed open vertically; This supporting has the coiling face and is used to clamp the receiving channel of this binding material in its winding area, and can rotate with respect to this guide, and according to the present invention, the coiling face of described supporting has a polygon basically, is preferably foursquare shape of cross section; This supporting is surrounded by extruder member of at least two spaces, and these at least two extruder members can and leave the motion of this supporting towards this supporting motion; The inside face of described extruder member part with this supporting coiling face on geometric configuration is close or identical.

In device of the present invention, the outside face of supporting and the inside face of extruder member concur in particularly advantageous mode.Based on the drift angle shape, the binding material of being reeled can very be out of shape consumingly at corner position, thus plastic deformation.Jia Gong strip coil or wire coil no longer are tending towards going the interfering expansion of back generation of loading by this way.Adopt this simple measure,, still can reel without difficulty and removing afterwards even at those binding materials that for example is easy to behind coiling, unclamp again (this unclamping again can occur spring steel or some plastics).A kind of outstanding being also advantageous in that batch up gear of the present invention had: do not require difference band and wire rod, because this relates to a kind of general-duty device.Also do not require the type of the raw MAT'L packing part of sending here being checked its binding material.Self-evident, for the soft binding material that is difficult for behind coiling, unclamping again, adopt batch up gear of the present invention still can take off without difficulty.

According to a kind of decision design of batch up gear of the present invention, the inside face of described extruder member is to have two horn shape inclined-planes towards the limit of described supporting leg, and the top crestal line on this horn shape inclined-plane is parallel to the pivot center of this supporting.In addition, the polygon of described formation supporting coiling face preferably waits the length of side.

More advantageously, the permissible variation between the bubble flare of described extruder member inside face and the described polygonal drift angle is ± 10 °.

The specific embodiment

Four main phase when Fig. 1 a-1d shows the parts of batch up gear of the present invention and its operation.Supporting 2 places between two

extruder members

5 and 6 with its coiling face 4.Binding material on the not shown part of will packing cuts off, unclamps and slowly pulls out.Then, binding material is delivered on the correct position in the face of batch up gear.At the state shown in Fig. 1 a, binding material 1 has been sent in the receiving channel 3 of supporting 2.In this running state, two

extruder members

5 and 6 and supporting 2 at a distance of bigger interval, so can bear the function of guide to binding material to be spooled.

Extruder member

5 and 6 inside face form one respectively towards supporting 2 open sidewall angle β=90 °.The top crestal line of this angle is parallel to pivot center 9 and extends.At this, the cross-sectional plane that dissects the coiling face 4 that this supporting 2 obtains perpendicularly with pivot center 9 has one and has the square shape of rounding drift angle a little.At this moment, apex angle be 360 ° divided by 4, equal 90 °.Rounded corner for example has the radius of curvature that is 10mm to the maximum, preferably is 1mm to the maximum.Mainly decide, can also especially preferably be about the radius of curvature of 0.1mm on pending binding material.Fig. 1 b shows by rotating the strip coil 10 that supporting 2 is constituted.At the crumpling process shown in ensuing Fig. 1 c, two

extruder members

5 and 6 direction motion and extruding towards supporting 2 for example utilize hydraulic actuating cylinder for this reason.So, the coiling face 4 akin strip coils 10 of the strip coil shown in Fig. 1 b 10 distortion a becoming shape and supporting 2 '.Such as already described, just make binding material generation plastic deformation with special effective and efficient manner.After

extruder member

5 and 6 was made split movement each other, the strip coil of this distortion is bulk to be opened, and fell as mobile vertically being pushed from this supporting 2 of lax stressless strip coil 10 ＂.For this reason, as shown in Figure 2, utilize the pushing piece 11 that on supporting 2, to make axial motion.

In Fig. 1 a, the winding position of this supporting 2 is arranged like this, makes binding material 1 to arrive supporting 2 zones through extruder member 5 and 6.In contrast, supporting 2 rotates like this in Fig. 1 c, makes coiling face 4 mate corresponding substantially mutually with the inside face of

extruder member

5 and 6.

Fig. 2 a-2c shows the embodiment according to winding head of the present invention when being in three kinds of difference in functionalitys, wherein saves the description to its detail.At this, winding head horizontal arrangement, that have a rotatable supporting 2 (pivot center 9) is provided with the coiling face in its winding area.Supporting cuts open mode with office and illustrates, thereby as seen to being positioned at release plunger 11 of wherein entreating and the push rod 12 that matches therewith.On this winding area, be provided with open ended, be used to clamp the receiving channel 3 of unshowned binding material herein.Last extruder member 5 and following extruder member 6 place with this coiling face 4 at a distance of big at least like this interval location place, thereby the strip coil 10 of the generation of reeling can be included in this middle cavity.This interval can be adjusted to maximum at whole winding process, so that reserve the space of using for strip coil when this process finishes, perhaps all the time with to become big strip coil gradually suitable and finish delivery band function.

Shown in Fig. 2 b, towards supporting 2 direction co-extruded, make the advantageous manner distortion of strip coil to have mentioned already by two extruder members.After two

extruder members

5 and 6 were separated from each other once more, the strip coil that is extruded was released, and to a certain degree bulk arranged slightly, can this released strip coil 10 ＂ be taken off from this device vertically by pushing piece 11 then.For this reason, push rod 12 is moved towards the working end of supporting 2.

Fig. 3 illustrates the preferred implementation of batch up gear of the present invention under some precondition.In this embodiment, different with the example among Fig. 1, this supporting 2 ' 360 ° of values of apex angle ' ratio divided by the drift angle number little.In situation shown in this figure, this drift angle is not 90 °, but 45 °, can also be other numerical value for the specific (special) requirements of binding material wherein, especially between the value of 45 ° and 90 °.Correspondingly, extruder member 5 ' and 6 ' adaptive with the profile phase of this supporting promptly are similar with its geometric configuration or identical.In illustrated case, bubble flare β ' has than apex angle ' big 2 ° value.The binding material that a kind of like this embodiment is particularly suitable for being made of plastics because at angle that winding process produced for example less than 90 ° (during quadrangles), can further reduce the bulk again tendency of opening of this binding material.

When particularly adopting plastics batch up gear of the present invention, can further improve its work by heating, this provides as an example in Fig. 4.This heating preferably can be realized by the heating wire 13 in the extruder member 5 " and 6 ".But also heater strip 14 can be installed in as a supplement or only supporting 2,2 ' in.Heating to binding material can also realize that perhaps the friction that for example produces by the extruder member rotation that makes strip coil and compress slightly realizes by ray between band and extruder member.These bands should be heated to such temperature, make this temperature surpass the plastics softening point at least at crooked place 15 places, mostly between 80 ℃ and 120 ℃.

The heating of batch up gear can also be finished in embodiment as shown in Figure 1.Most preferred structure is followed such requirement: design a kind of general-duty batch up gear, promptly design and a kind ofly not only be applicable to sheet metal strip but also be applicable to that the batch up gear of plastic strap may be crucial.Such as already described, when this batch up gear need not to change just can be used for different materials the time just very convenient in practice.If batch up gear as shown in fig. 5 is provided with heating member in extruder member and/or in supporting, can expect that it can process all binding materials without difficulty.The layout of heater strip and analogue can be arranged just in time in crooked place 15 places generation highest temperature.
