Description

Banding machine with a guiding frame

The present invention relates to a kind of banding machine with a guiding frame, its framework constitutes the passage that reverses of a rectangular cross section on the certain-length zone, and framework is by fixing and movable frame parts is formed, by the relative motion that framework drives and causes, this passage can be closed and opens so that penetrates band and reach at the length direction fastening belt.A kind of like this machine for example is used for the bundling to newspaper heap or parcel.Tie preferably makes and adopts various bandwidth and thickness by metal or tough and tensile plastics.

The characteristics of this machine are: guiding frame and wherein included passing through are penetrated passage that band forms the tie ring and are had space, i.e. San Wei curve.Tie forms tight bundle after the bale packing process of the object that is tied finishes, and has constituted many plane bands of knowing.Defined thus plane is called as the tie plane.After the band tension and leaving the conduction band passage, band just forwards to or is deformed in the tie plane in the machine of being considered.The tie ring changes into final aspect from spatial form.The whole fixing guiding frame that a plurality of thus parts are formed is configuration in this wise; Can be transmitted on a straight line drive path by the bundle object, and the tie plane also is positioned on the direction of transfer with turning.

Here the employed band that can not extend is that this curve of impassabitity transmits: if when the bent axle of this curve is vertical with the band plane.If band is forced to then need it is reversed when this curve track is advanced, promptly reverse around its longitudinal axis.Reason thus, non-planar guiding frame have complicated configuration.Actual orbital curve has comprised the necessary channel section of reversing.But this needs considerable technology cost to be used for cover panel and another movable frame parts, so that passage is opened and closure.

The banding machine type that relates in above-mentioned introduction is known in by DE-OS4100276.Wherein relate to a kind of intersection banding machine,, also above-mentioned shortcoming can occur if when considering to remove wherein transverse frame.Itself then have a plurality of motion frame partss for the conduction band frame that plays the effect of vertically tying up, all these parts all respectively have the drive magnet of oneself.

Such another kind of machine is proposed by German patent application P4139571.9.Wherein the upper component of guiding frame constitutes a plane framework, and therefore this section is implemented in a conventional manner and operated and open at least.

Be for the simple laterally conventional art of banding machine: the whole guiding frame that is parallel to the tie plane is divided into two parts, wherein have a groove in these two parts, and movable parts on perpendicular to the sense of motion of frame plane by being put on the fixed part.Above-mentioned thus groove and its cover panel have constituted the conduction band passage.

Task of the present invention is to create a kind of simple vertical banding machine that reaches reliable operation.

This task will be from a kind of banding machine of the described type of above-mentioned Introductory part, solve in this wise according to the present invention: a kind of banding machine with a guiding frame is provided, its framework constitutes the passage that reverses of a rectangular cross section on the certain-length zone, and framework is by fixing and movable frame parts is formed, the relative motion that drives and cause by framework, this passage can be closed and opens so that penetrates band and reach at the length direction fastening belt, wherein, being provided with one can straight-line frame parts, and it and a fixing frame parts combined action constitute a channel section of reversing.Wherein in principle, the configuration of the cross-sectional plane of these two parts of guiding frame makes that constituting the mutual of channel separation gap is a plane of reversing by putting face.But, the bending of channel plot is big more and windup-degree are big more, and the manufacturing of this frame parts is difficult more.A kind of favourable solution of described task is in a word: the section that the conduction band passage is big as far as possible be only bipartite their linear direction relative move back and forth so that save installation site and single driving device.Single parts are provided with fewly more, prevent that the tie reliability that mistake is deviate from from the conduction band passage is big more.

Have under the situation of reversing channel section that simple bending becomes three-dimensional curve, the making of guiding frame parts is being needed considerable cost.Therefore, in order to simplify manufacturing and to improve the precision that cooperatively interacts, to propose: parts, an especially movable frame parts have the complete cross section of a circular arc, vacate therein and have radially the channel cross-section that extends long center shaft, and another frame parts has a recessed cross section of identical or larger-diameter circular arc.The frame parts of configuration manufactures simple especially like this.They can not have movably each other by putting and closing groove with a snap by the frame parts that is recessed into arcuation, and this position for windup-degree also can be accomplished as a rule.This basic configuration also is applicable to the guiding frame section of passage embowment, in the initiation region of this arc passage reverse on the torsional direction and terminal area at arc on another torsional direction, reverse.Wherein passage can be through 90 ° or bigger radian, and the zone of windup-degree can be 90 ° or bigger, jumps in the tie plane at once as long as make to help tie like this.The cross-sectional plane that is recessed into arch of frame parts can be along channel change.As long as its marginal portion does not need for covering groove or constituting passage, this part can be cut off, and can make motion unlikely be obstructed of band when tension thus.Under the simple scenario of described circular-arc cross-sectional plane is a complete circular section.In the case, can be with a circular section material manufacture when making the parts of fluting, it is before milling out groove or be bent to required form later on.The available then welding of this circular section material or be threaded is connected with suitable strengthening part.On the other hand, lath or the plate material with respective circular edge also is suitable for.Can consider to use metal and plastics as raw MAT'L, wherein plastic material can be held and be used as mechanical the reinforcement by metal batten.

See from every side for realizing that the most favourable scheme of purpose of the present invention is: vertically the whole guiding frame with crooked three-dimensional trend of banding machine is made up of a single fixed parts and a single moveable element, but moveable element on even keel and on the direction of the angular bisector of the level curve of underframe section, being transmitted wherein.Fixing thus and movable parts can be combined by the frame section of varying cross-section, wherein always select simple cross-section shape for use, but utilize it to want to satisfy the requirement of operating technology.Especially must " sealing " live the conduction band passage, also promptly injecting when being with, tie is unlikely to come off out from passage by any little hole.In addition, also should be able to neither be clamped and do not collided unlikely being obstructed when after passage is opened, taking off band.Viewpoint proposes thus: the guiding frame with above-mentioned space curve is used to back twist frame parts that change and that have circular cross section at least and constitutes in the level curve section.It also can be with other arc or straight line and have reversing or the frame section of the conduction band passage that extends.Preferably clear-cut whole conduction band passage is made of a kind of like this global facility.

At last, the present invention is not confined to have on the cross-sectional plane of guiding frame of straight line or circular contact wire.Contact wire that is defiber also can be provided with like this, and promptly channel cross-section separates along the diagonal angle, and wherein defiber is vertical with the longitudinal central axis line basically.

Below will describe embodiments of the invention by accompanying drawing with different guiding frame cross-sectional planes.Accompanying drawing is:

Fig. 7: some cross sectional drawings that in Fig. 6, provide; And

Fig. 8: the example of another kind of guiding frame cross-sectional plane.

Fig. 1,3 and 5 described a guiding frame in the mode of signal, and in brief, this framework is by a S shape, the about lower curtate of horizontal direction, two perpendicular segment and a horizontal upper curtate are formed, and upper curtate intersects with the lower curtate diagonal angle.Represented at this to be the driving device of two belt conveyor 1 and 2 forms with long and short dash line among this external Fig. 1, it also can be push rod or other connecting gear, and its direction of transfer is by arrow 3 expressions.Certainly, belt conveyor also can move in the opposite direction.Conveyer is adjacent to be staggeredly arranged each other on direction of transfer, and is prolonging guiding frame extension shown in Figure 1 and coming.The lower frame part that Fig. 1 expresses S shape is not transmitted the device covering, thereby can make tie by stretching upward along the groove of lower frame shape trend in not shown transfer station and between conveyer.The bundling article 4 for the treatment of that is a rectangle at last is placed on the position of tie, and object is represented with long and short dash line among the figure.

More careful observations, the lower curtate of this guiding frame is made up of two segmental arcs 5 and 6, and each reaches right curved 90 ° left these two segmental arcs, and vacates space 7 therebetween.7 place has an envelope and takes the lead in the space, but it has only been described the top 8 of tabular cross motion.In the top view envelope take the lead and segmental arc 6 start-up portions between linear section on guiding frame curved a little downwards (decline), this sees the most clearly by Fig. 5.On horizontal segmental arc 6, connected a guiding segmental arc 9 that vertically makes progress, the back is the vertical section 10 to left handed twist again, a segmental arc 11, top linear portion 12, a segmental arc 13 that guides downwards, to the perpendicular segment 14 of left handed twist, be a segmental arc 15 at last once more, the latter carries out the transition in the lower curtate on the horizontal segmental arc 5.Upward bent the section that is connecting one section weak point on segmental arc 5, this Duan Zaiyu envelope takes the lead to join.

The tie of only in Fig. 5, expressing 16 on direction of transfer with transmit parallel plane band plane and advance and around coming along the guiding frame section of above-mentioned sequence.Its front end 17 wears out from segmental arc 5 at last, and envelope takes the lead band is tightened up then, and the cut-out of the band that will tie, two ends is sealed up each other again.

Especially at Fig. 1,2, see in 6 and 7, segmental arc 6 and the place ahead bonded assembly section be by one flat but also lath-shaped or 18, one circular sections of the fixed parts that other suitable stationary cross section is arranged rod configuration and have one radially the moveable element 19 of elongated slot 20 form.The narrow limit of this groove is covered by the inner cylinder face 21 of parts 18, and has constituted the conduction band passage 22 of the square-section that is represented by dotted lines in Fig. 1 top view thus.

Groove 20 was turned round an angle at bottom section, it turns round method for to reverse around center shaft along the length of circular section rod, and (penetrating on the direction at band) reverse 90 ° at first to the right, as cross sectional drawing a among Fig. 2, shown in b and the c, and near curve terminal the time again to 90 ° of left handed twists.Inner cylinder face 21 its radiuss of curvature of parts 18 are slightly larger than the radius of curvature of circular section rod, and the former shape is being followed the circular section rod on whole length, but are cut off covering groove 20 and N/R corner areas.This by cross section a among Fig. 2 and c to when showing in the top view.Therefore the upper limb 23 of parts 18 tiltedly comes to be covered with circular section rod 19 in top view, then tiltedly go back again, there fixed parts 18 seem with a crooked tongue portion be covered with the circular section rod.The circular section rod combines a kind of conduction band spare of formation with parts 18 thus, and forms good the cooperation.

Then 90 ° segmental arc 9 and back until the guiding frame section of section 15 form by the fixed parts 24 of a black iron panel configuration and a cubic cross-sectional plane rod configuration movable 25.This cross section, four directions rod is preferably by a kind of suitable smooth plastics, and for example a kind of PE Processing becomes.On a side adjacent, be provided with a label and be 26 longitudinal slot with black iron plate 24, it has identical size with groove 20, and it and black iron plate 24 synergies are extended down conduction band passage 22 seamless unoccupied places, the reversing and crookedly being formed jointly by these two

parts

24 and 25 of guiding frame section subsequently.The

upper curtate

11,12 of guiding frame and 13 and direction of transfer shape for example be 35 ° at an angle.Therewith correspondingly, two

sections

10 and 14 windup-degree are about 55 °.Segmental arc 15 passage is the most at last guided in the lower plane again.

So whole guiding frame is advanced along passage 22 and is had following section: take the lead the horizontal channel width edge in exit in envelope; Be bent downwardly part; The curve that reverses back and forth 6 in the horizontal direction; Upwards bend 90 ° curve 9 on the vertical direction; Change about 35 ° section 10 to left handed twist; Bent 90 ° curve 11 to horizontal direction; Take the lead to cross over crossing linear section 12 with envelope; Curved 90 ° curve 13 under vertical direction; To the about 35 ° section 14 of left handed twist; Curve 15 to curved 90 ° of horizontal direction; The curve 5 of taking the lead to reverse back and forth in a horizontal direction towards envelope; Bight portion makes progress; And, in the meeting point that terminal and envelope are taken the lead.Whole guiding frame like this is made up of fixed

parts

18,24,27 and

movable parts

19,25,28, the latter in the horizontal direction and greatly on the direction of the angular bisector of level curve 5,6 by leading.

It is outside the opposite sense beaming curve that segmental arc 5 is removed with segmental arc 6, and its structure is similar.Yet fixed parts 27 here constitutes and curves inwardly, and the groove of corresponding circular section rod 28 constitutes outwardly-bent.Here parts 27 also be covered with circular section rod and guaranteed parts in conjunction with the time guiding function and to the reliable covering of groove.

In order to be easy to that all links, reinforcing member and guide have been omitted in described graphic understanding, although they are important to finishing of practical structures of the present invention.The circular section rod is with welding or be threaded in a rail bar or a corresponding framework side, so that formation connects and is fixed in the position in its space each other.Preferably utilize angle bar spare to replace black iron plate 24, because it has higher rigidity.Yet be important to note that: each section all said fixing and movable frame parts is connected to each other with suitable method, and itself is presented as the structure of rigidity.The moveable element that is combined into like this is bearing in the sliding guide movably, makes can move to and fro on the angular bisector direction of segmental arc 5 and 6, as shown in arrow 29 (opening direction) and 30 (closing directions).Fig. 6 expresses open position and closing direction.Move back and forth to movable and fixed frame element and its bearing of trend oblique, and as another consequence, these two formation single-pieces parts have the distance that differs from one another everywhere in open position, but this is inessential for its function.Important is: tie is opened the back in tension at the conduction band passage has enough positions to be drawn out from passage.This point has been guaranteed as illustrated in fig. 6.It is opened motion and for example carries out by four pneumatic pistons drivings and with burst mode.Thus, the embodiment by above-mentioned guiding frame has reached band is jumped in the predetermined tie face of taking the lead by envelope, and need not the leading parts and push away tape member.

Fig. 8 represents the modification of the cross-sectional configuration of two guiding frame parts.Here be provided with two

coefficient sliding parts

31 and 32, at the other conduction band passage 33 that formed of their contact surface.In the case, all constitute a broadside and a narrow limit in conduction band passage 33 cross sections on each in these two sliding parts.Other contact surface zone has constituted Separation 34, and this gap is perpendicular with the band plane, and this enters frictionally for the band nothing is important.In four section drawing l to o, express the conduction band passage and reversed 90 °.By the configuration of the local wedge shape of contact surface, also obtained sliding part that polymerization gets up good accurately putting in place when guiding and conduction band passage closure state each other here, do not enter frictionally so that guarantee that band do not have.
