Apparatus for separating a strand of plastic material with a carrier carrying a notching device and a cutting device

The invention relates to a device for separating a strand of plastic material, in particular clay, which can be moved along a conveying passage, in longitudinal sections according to the preamble of claim 1 or 2 or 3.

A device of this kind is described in DE 10 2005 021 038 A1. In this prior art device, the notching device is disposed on a frame-shaped support extending transversely to the passage, wherein a plurality of supports each having an associated notching device in the longitudinal direction of the passage can be arranged one behind the other and wherein each notching device is associated with a cutting device with a cutting wire which transversely extends to the passage and is movable from the one side of the passage to the opposite side and back.

The invention has for its object to simplify a device of the type specified. This simplification is intended to improve the construction and / or the assembly or disassembly of the carrier.

This object is solved by the features of claim 1. Advantageous developments of the invention are described in the appended subclaims.

In the device according to the invention according to claim 1, the cutting device with its cutting wire holders and their cutting wire guide on the carrier is arranged. As a result, the carrier supporting part not only for the notching device, but also for the cutting device and it is the construction due to the arrangement of the cutting device on the carrier much easier, because accounts for further parts of the device attachment features for the cutting device. In addition, the carrier can be prefabricated with the cutting device, which likewise leads to a simplification and enables cost-effective production. Another advantage is that there is no need for any special assembly measures for mounting the cutting device on other parts of the device, since the cutting device is mounted on the carrier, preferably by prefabrication. Another advantage is that the carrier as a largely prefabricated unit the device is mountable, z. B. on a longitudinally displaceable slide back and forth of the device is mounted, in particular by a transversely directed mounting movement, preferably from above, and in the opposite disassembly direction is removable.

It is also advantageous to arrange a cutting drive on the carrier module, so that the cutting device is arranged with at least one cutting element holder and an associated cutting guide and one or a common cutting drive on the carrier module. In this embodiment, thus also the cutting drive on the carrier module can be prefabricated or mounted.

The object is also solved by the features of independent claim 2. In this embodiment according to the invention, the relevant notching strip is pivotally mounted in its one end region in a pivot joint with a hinge axis extending parallel to the passage. As a result, the notched strip is mounted in its one end by the pivot joint not only in a simple construction but also stable and störungsunanfallig. This advantageous embodiment is also advantageous for the oppositely arranged notching strip, in particular for an upper and / or lower notching strip or notching strips.

Another advantage of this embodiment of the invention is that the pivot drive for the pivotable notch not only in a simple way not only on one side, z. B. offset to the outside, can be arranged, but also for two mutually oppositely arranged pivotable notching a common mer pivot drive or spreading and contraction drive, can be used. The outwardly offset relative to the passage swivel joint may be offset in the longitudinal direction of the notched strip or a pivot lever or swing arm carrying it.

When notches, ie when penetrating the notched strips in the z. As ceramic material of the strand, the notch strips exert a pressure on the strand, which can lead in particular to a shift of the strand when the strand is notched sideways. In the case of laterally simultaneous notches, the lateral compressive stresses can indeed cancel, but this only takes place if the consistency or strength of the strand material is the same. Consequently, in practice, there are circumstances where there is a risk that due to different Kerbbeanspruchungen the strand is moved transversely, which is of course undesirable and affects the further treatment of the strand. The invention is therefore based on the object, a device according to the preamble of claim 3 in such a way that it is able to exert a stabilization on the strand.

This object is solved by the features of independent claim 3. Advantageous developments of the invention are described in the appended subclaims.

In the embodiment according to the invention according to claim 3, the device has on both sides of the passage in each case a support strip with a support surface which extends parallel to the longitudinal axis of the passage, wherein the distance between the support strips of the transverse dimension of the strand corresponds and the support surfaces of the support strips on the strand concern and thus support this. As a result, the strand receives a lateral support, whereby the risk of lateral displacement is prevented or at least largely reduced.

In order to adapt the support strips to different widths of the strand, it is advantageous to arrange the support strips side adjustable and form. Such a configuration also makes it possible to set the support strips initially wider than required for constant strand widths and later to move them inward to such an extent during functional operation that the support surfaces rest on the strand or can perform a guiding function.

A special drive for the support strips can be omitted if the support strips are fastened to the notching strips on their sides and can thus be moved by the drives of the notching strips. In this case, the support strips can be fastened on the inside to the notching strips and / or protrude from these to the rear. It is essential that the notched ridges of the notched strips project beyond the support surfaces of the support strips or notching strips by the depth of the notches, so that in the notch end position the support surfaces abut the strand.

The invention also includes embodiments independent of claims 1 and 2 and 3, which relate to a cutting device according to claim 6 and a suspension device according to claim 25 for one or more carrier modules.

The embodiments according to the invention are particularly advantageous for notching strips which are each formed by two chamfering strips which have a distance extending from one another along the passage, wherein the cutting wire of the cutting device is movable transversely to the passage between the chamfering strips. By the invention, the Anfasleisten are not only stabilized both by the pivot arms themselves and by the storage, but they can also be arranged in each case on its own pivot arm, wherein the associated pivot arms have a longitudinally directed the passage distance from each other. This distance is good for the length of the strand sections to be cut. In other words, in this embodiment, chamfering strips required for a strand longitudinal section can be arranged on both sides of the relevant module carrier, which preferably form a movement unit which can be moved in a simple manner by a drive.

Advantageous and expedient embodiment of the invention will be explained in more detail with reference to exemplary embodiments and drawings shown in simplified form. It shows

The designated in its entirety by 1 device consists of several component units such. B. a standing on the ground frame (not shown) in which a extending in the longitudinal direction free passage 2 for the strand 3 (Fig. 6) is arranged. To separate the strand 3 in strand longitudinal sections 3 a at least one cutting device 4 is provided with a transverse to the passage 2 extending cutting wire 4 a, wherein the strand 3 is provided prior to cutting on all sides with preferably arranged in a common transverse plane notches 5 a which extend transversely, and in which the plastic material of the strand 3 is cut transversely. Due to the cutting in the notches 5a, a degree of cutting protruding beyond the outer surfaces of the strand sections 3a is avoided in each case.

To convey the strand 3 through the device 1 in the passage 2 is a strand 3 preferably continuously advancing conveyor Ia (Fig. 6), with a plurality of successively arranged in the passage direction 2a conveyor sections, z. B. depending on a conveyor belt may be formed. The strand 3 can pass from an extruder on or into the conveyor Ia.

Notching and cutting preferably take place during the passage of the strand 3. A slide S known per se, which carries one or more carrier modules 9 arranged one behind the other with a notching device 5 and a cutting device 4, is displaceable in the direction of passage 2a and at notching and cutting with the advancing speed of the strand 3 is moved before and then moved back to its original position, from which a next notching and cutting process takes place. During the advancement of the carrier module 9 with the notching device 5 and the cutting device 4, the cutting wire 4a for cutting can always be moved from one side of the passage to the other side and be moved back again after a spread of the separated longitudinal section 3a during an idle stroke is referred to as unilateral or monodi- rectional cutting (known per se). However, it is also a reciprocal or bidirectional cutting possible in which the cutting wire 4a during a forward movement from one side to the other side and after a return movement and in the next forward movement without the above spread back to one side is moved (also per se known).

The device 1 is in principle operable with only one cutting device 4 and only one notching device 5, which is arranged and supported on a single support module 9, which extends transversely to the passage 2 from one side to the other side and is preferably designed as a frame , In this case, the carrier module 9 may be plate-shaped and arranged edgewise and have a cross-sectional size of the passage 2 approximately corresponding through hole 11.

For attachment of the carrier module 9 on the slide is a simplified connection device 12, with which the carrier module 9 preferably by a transverse mounting movement, for. B. from above or from one of the two horizontal sides, mountable and disassembled again for disassembly, wherein the Trägerermo- module 9 with the notching device 5 and the cutting device 4 forms a preassemblable modular unit 32, which can be mounted in the device 1 and disassembled ,

In the drawing figures, the connecting device 12 by a quick-closing connection, z. B. by a connector 13 with a to one side (not shown) or upward (shown in the drawing) open jack or plug-in recess 13a formed, in which the carrier module 9 inserted from the respective side with a matching spigot 13b and by a detachable Secured element 13c is secured, z. B. by a locking screw or a locking pin that includes an attachment of the frame or enclosing it and z. B. in a plug hole in the support module 9 borders. The connecting device 12 will be described in more detail below. To increase the performance and efficient production of the longitudinal sections 3a, it is advantageous, according to FIG. 4 and following several such support modules 9 in the passage direction 2a to be arranged one behind the other, so that the strand 3 can be serrated and cut in several successively arranged cutting planes El. Preferably, the motion control of the notching device 5 and the

Cutting device 4 is formed so that all four notching tools 8a to 8d and all cutting wires 4a are moved simultaneously. Since the carrier modules 9 are identical, only one carrier module 9 needs to be described.

The one or more support modules 9 are positioned along the mounting direction releasably on the slider S, z. B. by the fuse element 13c.

As can be seen in particular in FIG. 1, the carrier module 9 is formed by a plate-shaped frame 9 a, whose two horizontal and vertical frame sections delimit the quadrangular through-hole 11. The passage 2 is located in the through hole 11, the latter being measured larger in cross section than the passage 2, so that between the inner edge of the frame sections and the passage 2, two opposing lateral notching tools 8a, 8c, an upper notching tool 8b and a lower notching tool 8d Have space. The notching tools are movable transversely to the center axis 2b of the passage 2 between a notch starting position releasing the free passage 2 for the strand 3 and a notching position encompassing the strand 3 around the notch depth.

In the present embodiment, all four notching tools are formed by notched bars 8e, whose transversely to the passage 2 extending length are adapted to the transverse dimensions of the strand 3, that they press in their notch positions a circumferential notch 5a in the strand. Of the four existing notching strips 8e, two opposing notching strips 8e, here the upper and lower notching strips 8e, are formed so long that their end regions overlap the other two notching strips 8e at least in their notched position.

In the context of the invention, the notching strips may have the cross-sectional shape of a symmetrically arranged with respect to the vertical wedge whose wedge angle z. B. is about 90 ° (not shown). In such a known Kerbvor- direction 8 are z. B. arranged in a common transverse plane El notched bars with respect to the cutting plane El and the cutting device 4 in the passage direction by the length of a strand section 3 a arranged offset. In the present embodiment are - as shown in FIG. 2 and following show the notching device 5 and the associated cutting device 4 in a common vertical transverse or sectional plane El, wherein the notching device 5 is formed by a known chamfering device 14 which is connected to the Riming of the front ends of the longitudinal sections 3a or blanks 14a to be cut still pressed into the strand 3, wherein in each case two mutually adjacent chamfers 14a on the cutting plane El form a common notch 5a. In this embodiment, on all four sides of the conveying passage 2, two notched strips 8e divided in their longitudinal direction, namely so-called chamfering strips 15, are arranged parallel to each other, which - seen transversely to the passage 2 - correspond to the embodiment of undivided notching strips 4e. In this case, however, the Anfasleisten 15 a extending along the passage 2 distance a from each other and thus a slot 15a between them, which corresponds to taking into account a movement of the cross-sectional dimension of the preferably circular cutting wire 4a. In this embodiment, the notches and the cutting can be done simultaneously, the Anfasleisten 15 not only provide the cutting wire 4a a guide, but also prevent warping of the strand material or cutting burrs.

The chamfer surfaces 15c corresponding to the desired cross-sectional shape of the chamfers 14a on the chamfering strips 15 are preferably also wedge surfaces which, with the transverse cutting plane El, enclose an acute angle Wl of, in particular, approximately 45 °, so that the common notch angle is approximately 90 °.

Seen transversely to the passage direction 2a, two chamfering strips 15 are each arranged in a mirror image in the region of the sectional plane E1, their chamfering surfaces 15c facing away from each other and their mutually facing side surface 15b extending parallel or with a clearance angle to the associated cutting plane El. These two Anfasleisten 15 form a Kerbbewegungseinheit and they can, in particular as upper chamfers 15, by a z. B. plate-shaped base member 16 connected to each other and worn thereon.

The notching tool 8a to 8d thus formed is movable back and forth in a transverse guide 17 by a notch drive 18 transversely between the notch initial position and the notch position. The transverse guide 17 can be formed by one or two guide rods 17a spaced apart from one another, which are displaceably mounted in corresponding guide holes in the associated carrier module 9. The notch drive 18 may, for. B. be formed by a cylinder piston drive, the cylinder is supported on the support module 9 and the piston rod engages the base part 16. In the present exemplary embodiment, two mutually opposite notching tools, preferably the upper and lower notching tools 8b, 8d, are each arranged on an associated pivot arm 18b, in particular projecting from each other, wherein the pivot arms 18b in their end regions on one side of the passage 2 in Swivel joints 19 pivotally mounted with horizontal hinge pin 19a in the associated transverse plane. As a notch drive 18 may in this embodiment a, z. B. for both pivot arms 18b common, notch drive 18 serve, for. B. also a cylinder piston drive 18a, which is disposed between the end portions of the pivot arms 18b on the other side, in particular outside the associated support module 9, and preferably pivotally connected to the pivot arms 18b. The pivot arms 18b project beyond the notched ledges 8e at both ends, namely on the bearing side beyond the passage 2 into the region of the frame-shaped support module 9, in the region of which the pivot joint 19 is arranged, and beyond the support module 9 at the other end.

For the notching tools 8b, 8d or notching ledges 8e carried on the swivel arms 18b, the guide 17 is formed by the swivel joints 19 and / or the abutment of the swivel arms 18b on the rear or front side of the carrier module 9.

The two mutually associated pivot arms 18b are arranged on the front and back of the carrier module 9. This embodiment counteracts the longitudinally directed outer spacing of the respective chamfering strips 15 arranged on the base part 16.

As particularly shown in FIG. 6, the two swivel arms 18b adjacent to the associated cutting plane El have at least the sliding distance a for the cutting wire 4a from one another.

To clarify both the initial position and the notch position of Anfasleisten 15 Fig. 6 shows the upper Anfasleisten 15 in the starting position and the lower Anfasleisten 15 in the notch position.

The notching strips 8e or their drives are assigned stops Al, A2, the notch movement of the notching strips 8e in the notch position and z. B. limit even in the starting position. For the pivot arms 18 b can, for. B. strip-shaped, stops Al, A2 at the pivot joints 19 remote from the end portions of the rear and / or front side of the modules 9, in particular on the inside between and and z. B. also on the outside of the pivot arms 18b.

The lower Anfasleisten 15 can z. B. be arranged vertically and in front and rear recesses 23 of the associated base member 16 and be fixed, each supporting the associated Anfasleiste 15 with a step surface 23 a, on which the Anfasleiste 15 rests and thus rests laterally and underside (Fig and 3).

As can be seen in particular in FIG. 3 in the lower left or front corner regions, the two overlapping notching strips 8e or chamfering strips 15 can be adapted with their end-side end faces 15d to the contour or bevel of the notched face 15c of the adjacent overlapping chamfering strip 15 the overlapped Anfasleisten 15 at their overlapping Anfasleisten 15 facing end faces 15d, z. B. are formed obliquely and abut the Anfasflächen 15c in the notch position. As a result, circumferential chamfers 14a are notched, and the Anfasleisten 15 stabilized by a mutual investment and support.

However, the chamfers 15 can also be connected in one or two parts to the associated swivel arm 18b, with an associated connecting web preferably extending in the vertical projection of the associated swivel arm 18b in order to minimize space in the longitudinal direction (FIG. 6 below) ).

To stabilize the attachment of Anfasleisten 15 also serve two other embodiments of FIG. 6. The upper and / or lower Anfasleisten 15 are formed by obliquely arranged, in itself flat strips that form the Anfasflächen 15c with their inner broad sides and its outer sides facing away forming the side surfaces 15b. This oblique Anfasleisten 15 can be used in accordance with oblique grooves 22 in the associated base parts 16 and fixed.

As can be seen from Fig.6, the lower Anfasleisten 15 are also arranged obliquely in the above sense, but they are fixed by vertical webs 15e on the associated lower pivot arms 19b.

Between the lower chamfer strips 15 are, for example, plate-shaped support members 30 whose tops are at the level of the top of the existing conveyor Ia for the strand 3, and which are supported at the bottom of the associated support module 9, 9b, 9c, 9d, eg directly on the lower frame portion of the frame-shaped carrier module 9, 9b, 9c, 9d. To hold the longitudinal spacing a from each other having Anfasleisten 15 requires at least two support modules 9, which also have at least the distance a from each other for the cutting wire 4a and wear the Anfasleisten 15 on the four peripheral sides in the region of their sides facing each other.

For simultaneous notches on all four sides and cutting of the strand 3 in at least one of the desired length Ll of the longitudinal sections 3a corresponding distance c from each other, it is advantageous to arrange three or more support modules 9, of which the initial module 9b the back Anfasleisten 15 of the first chamfer The middle module 9c supports the front chamfers 15 of the first chamfer strip arrangement in the area of its rear side and the rear chamfers 15 of the second chamfer strip arrangement in the region of its front side and the third carrier module or end module 9d carries the front chamfers 15 of the second chamfer strip arrangement. In the exemplary embodiment, five carrier modules 9 are arranged one behind the other, wherein four notches 5a are attached substantially simultaneously and four longitudinal sections 3a can be separated.

The chamfers 15 belonging to the central carrier modules 9c, namely the front chamfering strips 15 of the first chamfering strip arrangement and the rear chamfering strips 15 of the second chamfering strip arrangement are preferably fastened respectively to the associated base part 16, which is e.g. B. on the pivot levers 18b of the associated central module 9d is preferably attached to the underside.

Between the base parts 16 and the carrier modules 9, 9b, 9c, 9d there are vertical or horizontally extending free spaces 20 which allow the chamfers 15 to move outwardly beyond the starting position for larger passage cross sections.

Both when only one module 9 with a cutting device 4 arranged and held thereon and when a plurality of carrier modules 9 are provided with arranged and held cutting devices 4, each cutting device 4 at least two cutting wire holder 4b 1, 4b2, respectively a holder guide 25 transversely to the passage 2, in the present embodiment, horizontally, slidably guided and therein in each case by a cutting drive 26 are movable back and forth, in particular both wire holders 24 are simultaneously and preferably evenly displaceable. There may be arranged two holder guides 25 in the upper and lower region of the associated carrier module 9, for. B. at the top and bottom. The present at least one cutting device 4 thus has an independent feature because it is formed with two cutting wires 4al, 4a2, which are arranged on both sides of the associated support module 9 in two longitudinally spaced planes E, the distance c is substantially the sum of the Length Ll of the longitudinal sections 3 a plus the cross-sectional dimension d of the cutting wire 4a corresponds. This distance c is greater than the longitudinal dimension e of the support module 9, which may be the outer dimension of the pivot arms 18b. The cutting wires 4al, 4a2 can be held by two front side cutting wire holders 4b 1, 4b2, respectively, and corresponding rear side cutting wire holders.

The cutting wires 4a 1, 4a2 are preferably formed by a common cutting wire 4a, which is deflected in at least one associated edge region of the carrier module 9, for. B. by a deflection device 27 with a deflecting z. B. may be a round slider or a rotatably mounted roller and disposed on or in the associated wire holder 24 and rotatably supported.

In the present embodiment, the cutting device 4 and their arrangements on the associated carrier module 9 are each formed the same, so that only one cutting device 4 needs to be described.

If both cutting wires 4al, 4a2 are formed by a common deflected cutting wire 4a, it is advantageous to simplify the construction, to arrange this cutting device 4 with two cutting wires 4a 1, 4a2 on the associated support module 9 and hold. Therefore, in the presence of only a double-sided cutting device 4, only the center module 9c needs to be formed with this double cutting device 4, and in the presence of more than three support modules 9, only every second center module 9c will be formed with the cutting device 4, as shown in FIG.

The wire holders 24 may each be formed on a slider 24 a, on which the cutting drive 26 engages, and which is mounted displaceably in the holder guide 25. In the exemplary embodiment, the holder guide 25 is formed by a respectively arranged on the underside and top of the center module 9c guide rail 28a on which the associated slider 25a is slidably guided with a matching guide element. As a cutting drive 26 can, for. B. serve a cylinder piston drive or spindle drive. In the notch initial position shown in FIGS. 1, 2 and 4, the cutting wire 4a or the cutting wires 4al, 4a2 is located in the edge region of one side of the passage 2, for example in the region or on the outside of the vertical Notching ledges 8e or base parts 16. From this position, the at least one cutting wire can be moved in the opposite edge region of the passage 2.

The distance regions of the distance a facing away from the longitudinal axis 2 a of the passage 2 b are preferably designed to be divergent outwards, in particular when the cutting wire 4 a is displaced outwards with respect to the notching strips in the notch starting position. As a result, the threading of the cutting wire 4a is improved. According to FIGS. 2 and 3, oblique or rounded insertion surfaces 15f are provided at the ends on the chamfer strips 15.

The two wire holders 24 or the associated slides 24a or their guide elements can be mechanically coupled to one another to improve the movement drive and / or be movable via an externally acting lever (not shown).

The cutting device 4 is preferably associated with a tensioning device 29, which with one end of the one-sided arranged or deflected cutting wire 4a; 4al, 4a2 is connected.

The tensioning device 29 can by a second deflection device 31 with a second, z. B. rotatably mounted, Unlenkelement be connected.

In this case, two deflection devices 27, 31a, 31b may be provided, of which the first 31a deflects the upwardly extending cutting wire horizontally and approximately parallel to the passage 2, and the second 31b deflects the cutting wire horizontally outward toward the tensioning device 29. In the present exemplary embodiment, an end fastening device 33 or hooking device for the cutting wire z. B. in the region of the same side as the clamping device 29 is arranged.

Alternatively, the cutting device 4 may be formed with a wire unwinding and winding device and an associated drive, so that the cutting wire can be moved permanently or from time to time in its longitudinal direction.

It is particularly advantageous, in a device 1 with only one carrier module 9 or more along the conveyor passage 2 successively arranged carrier modules 9 or the carrier modules 9 by a Aufhahmevorrichtung 31 to a modular unit preferably detachably connected by the connecting device 12 with the slider S connectable and thus mountable and disassembled and is exchangeable, preferably by a transverse to the passage 2, in particular vertically directed assembly or disassembly movement.

The receiving device 31 has at least two mutually opposite sides arranged and parallel to the passage 2 extending Aufhahmestangen 33, on which or the carrier modules 9 are fitted with matching receiving holes 34 therein. Preferably, to increase the stability of the module assembly 32, more than two support rods 33 are provided, which extend through receiving holes 34, which are preferably arranged in the upper and lower regions of the support module (s) 9. In the present exemplary embodiments, four receiving rods 33 are provided, which extend through four receiving holes 34, which are arranged in the corner regions of the carrier module or modules 9. The distance f (Fig. 1) extending transversely to the passage 2 and transversely to the cutting wires 4a and 4a 1, 4a2 between the receiving rods 33 is greater than the distance g of the cutting wires 4a in their two cutting end positions, so that the receiving rods 33 themselves are outside of the cutting area or passage 2 and do not hinder this.

The carrier modules 9 can by means arranged on the connecting rods 33 distance pieces 37 a, z. B. spacers to be held at a longitudinal distance from each other.

The modular unit 32 can be pre-assembled with carrier modules 9 of optional number, so that a desired prefabricated receiving device 31 can be mounted quickly. In this case, the desired handling-friendly and rapid disassembly and / or assembly can be achieved by a connection device 12 in the form of a quick-release connection, in particular in the form of a plug connection 13.

In the present exemplary embodiments with a plurality of carrier modules 9 arranged one behind the other, two connecting devices 12 arranged one behind the other are provided on both sides of the passage, in order to increase the stability of the attachment.

The connecting devices 12 are mirror images of a vertical longitudinal center plane E2 of the passage 2 and the device 1, respectively.

The connecting parts of the connecting device 12 associated with the slider S are designated 12a, and the connecting parts associated with the modular unit 32 are designated 12b. In the context of the invention, the latter connection parts 12b can also be arranged on the support module or modules 9.
