Description

 Device for separating a plastic strand movable along a conveyor passage, with a notch drive

The invention relates to a device according to the preamble of claim 1 or 3.

A device according to the preamble of claim 1 is described in WO 2006/119929 A2. In this prior art device, the notching device on four notching strips, which are arranged in a transverse plane of the passage and each movable by a separate drive between a rectangular cross section of the passage releasing starting position and a dipping into the strand notch position. The notching strips and the drives are each arranged on a transversely extending to the passage frame-shaped support, with which they form a support module.

The device is provided with a cutting device for cutting the strand into the notches produced by the notching strips. The notching strips may be so-called undivided or split notching strips. Undivided notching strips have a wedge-shaped cross-sectional shape. Divided notching ledges are each formed by two chamfering ledges extending side by side in the circumferential direction of the conveying passage and spaced apart from each other in the longitudinal direction of the conveying passage, the cutting means comprising a cutting wire extending between the chamfering bars across the conveying passage or through the conveying passage Notched ridges when notched limited cross-section is movable. In the presence of undivided notching strips cutting longitudinally offset after notching takes place in a particular cutting plane. At the

The presence of split notching strips results in cutting immediately after notching in a common notching and cutting plane. In this case, a plurality of notching devices with associated cutting devices along the passage can be arranged one behind the other and be actuated substantially simultaneously, wherein the Anfasleisten are each movable by a pair of piston cylinders, each at the Rear side of a frame-shaped carrier are held. In this case, the Anfasleisten extend so far in the longitudinal direction of the passage through the through hole in the associated frame-shaped carrier to the front side, so that the gap between two belonging Anfasleisten is located between two support frame. The associated cutting device is arranged so that the cutting wire between these support frame in the gap between the Anfasleisten is movable across the passage.

The invention has for its object to improve the notch drive in a device according to the preamble of claim 1 or 3. Furthermore, the notch process and the notch quality are to be improved.

This object is solved by the features of claim 1 or 3.

The invention is based on the finding that, due to the presence of a notching strip arranged on one side of the passage, a drive movement directed in a circumferential direction of the passage is particularly favorable and should enable space-favorable designs for the notch drive. This drive movement is particularly favorable when a plurality of notching strips are arranged on several sides of the passage.

In the embodiment according to the invention according to claim 1, the drive elements are each drivingly connected to a base element of a transmission, that converts a directed in a circumferential direction of the passage movement of the base element in the transverse movement of the associated notching strip. Here, a directed in the circumferential direction of the passage drive movement is utilized, the direction and effective range allows a space-favorable arrangement and design of the associated notch drive part. It is therefore possible to realize a space-saving construction of the notch drive parts, which has a small dimension in the longitudinal direction of the passage, and is therefore particularly well suited for the notch drive.

The invention is further based on the finding that the drive movement extending in the circumferential direction of the passage makes it easier Way allows to connect the distributed on the circumference arranged base elements of the notch drive with each other, so that the notch strip can be moved not only simultaneously, but also with a common drive motor.

In the embodiment according to the invention according to claim 3, the notch guide for the notching strip is arranged obliquely, wherein it includes an acute angle with the following in a circumferential direction of the passage horizontal or vertical. In this embodiment, due to the obliquely directed notch guide a larger drive path for notches available as it is the case with known embodiments in which the notch guide is directed vertically and horizontally. In addition, the score bar performs a lateral transverse movement corresponding to the magnitude of the skew with respect to the vertical longitudinal plane of the passage, which also has a positive effect on the notches and in particular on the notch quality.

Another advantage of this embodiment of the invention is that it is particularly well suited for Kerbleisten that overlap each other in the corner areas and are permanently adjacent to each other. However, the invention is not limited to this particular notch power design.

Both embodiments of the invention are particularly suitable for a notching device whose notching strips are arranged and movable in a common transverse plane. These can be undivided or so-called split notching strips.

For both embodiments according to the invention, it is also very advantageous for a square or square cross-sectional shape of the notched strip in which two notches overlap the other notched bar in the corner area and have a recess in the facing end face into which the notch bar forms a notched bar closing encloses. Such Kerbleistenausgestaltung allows movement of the notch strips in constant contact with contact in the corner areas, so that when notching material of the strand can get in the corner areas between the notch strips. In both embodiments of the invention, it is advantageous to increase the work capacity to provide two or more in the longitudinal direction of the passage one behind the other and spaced groups of combined notching and cutting devices, which are essentially simultaneously movable for notching or chamfering and cutting. In this refinement, a plurality of longitudinal sections can thus be notched and cut substantially simultaneously.

Both embodiments of the invention are suitable for a cutting device in which one cutting wire holder is movable in the circumferential direction of the passage and the other cutting wire holder is stationary, preferably on one of the two support frame, which can be extended laterally for storage of this stationary cutting wire holder, so that stationary cutting wire holder can be arranged outside a ring guide for the movable cutting wire holder.

A further advantage of the invention is to move the at least one notching strip in each case with a drive element that is drivingly connected to a base element of a transmission in such a way that a movement of the base element directed in a circumferential direction of the passage converts into a transverse movement of the associated notching strip. This embodiment makes it possible to perform the notches with a desired notching speed, which can be determined by the transmission ratio of the transmission. For this purpose, different transmission designs can be integrated, with a simple and small construction for the transmission can be realized. As a transmission element, a connecting rod is very well, which converts the directed in the circumferential direction movement of the base member in the transverse movement of the notch strip. The arrangement of a connecting rod further allows a degressive notch speed when notching, which has a favorable effect on the increasing displacement of the material to be notched during notches. In addition, with a connecting rod can generate a notch progressive notch force. Further developments of the invention allow simple and small detail constructions of the device, which also ensure a simplified assembly and disassembly and a cost-effective production.

Below, advantageous embodiments of the invention will be explained in more detail with reference to several embodiments and drawings.

The designated in its entirety by 1 device consists of several component units, with z. B. a standing on the ground frame G (only indicated in Fig. 1), in which a extending in the longitudinal direction of the free conveying passage 2 is arranged for the strand 3. At least one cutting device 4 with a cutting wire 4 a extending transversely to the passage 2 is provided for separating the strand 3 into strand longitudinal sections 3 a, wherein the strand 3 is provided on all sides before cutting, preferably with notches 5 a arranged in a common transverse plane. 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 cutting burr is avoided or reduced, in particular, in each case a cutting burr protruding beyond the outer surfaces of the strand sections 3a is avoided. Depending on the requirements of the edge condition of the producible with the device 1 by cutting strand longitudinal sections 3 a, it may be sufficient to arrange a notched strip 6 on one side or two notching strips 6 on two opposite sides of the passage 2, which arranged in a common transverse plane Notches 5 a on two opposite sides of the strand 3 can be pressed, wherein the pressure forces arising during notches substantially cancel due to the opposing arrangement. But it may also be sufficient to arrange for a three-sided notches three notching strips 6 in the common transverse plane surrounding the strand 3 or passage 2 in the region of two adjacent corners. The third notching strip 6 extending between these two opposing notching strips 6 is preferably an upper notching strip 6c. In such an arrangement without an underside notching strip 6a, the strand 3 or the longitudinal sections 3a are only notched laterally and on the upper side. For demanding longitudinal sections 3a, the device 1 on all four sides notching strips 6 for pressing a circumferential notch 5a.

The cutting wire 4a is held under a tension of the cutting wire 4a by two cutting means 24a, 24b spaced transversely from each other and disposed on the passage 2, the cutting wire holders 24a, 24b being transversely extended from one to the other side of the passage 2 by a cutter shown only in FIG 8 and the following illustrated cutting drive 26 are movable. In all exemplary embodiments, identical or comparable parts are designated by the same reference numerals.

To convey the strand 3 from the back to the front 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 or Auflager- sections may be formed. The strand 3 can pass from an extruder on or into the conveyor Ia.

The notching and cutting preferably takes place during the passage of the strand 3. For this purpose, a slide S known per se may be arranged, which has at least one support module 9 with a notching device 5 and a longitudinally offset cutting device 4 (in FIGS not shown) or a carrier module 9 with at least one notching device 5 and a longitudinally offset to the rear carrier module 9 with at least one cutting device 4 (in Fig. 6 exemplified) carries along the passage direction 2a back and forth and when notching and cutting is moved with the Vorbewegungsgeschwindigkeit of the strand 3 before and then moved back to its original position, from which a next notching and cutting process can take place. During the advancement of the at least one 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 2 to the other side and moved back after a spread of the separate longitudinal section 3a in a no-load stroke , which is called unilateral or mono-directional 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 slider S may be a plate-shaped carrier, and it is mounted with guide bushes 10a arranged on it along guide passageways 10b extending along the passage 2 and displaceable back and forth by a longitudinal drive 10c. The guide rods 10b are mounted on the frame G by means of bearing blocks 10d. To move the slider S in the z. B. thus formed and designated 10 Längsfiihrung the longitudinal drive 10c aurweisen a suitable displacement motor aurweisen.

The device 1 is in principle operable with only one notching device 5 and only one indicated in Fig. 6 cutting device 4, each of which may be arranged and supported on a support module 9, which extends transversely to the passage 2 from one side to the other side, and preferably is formed frame-shaped. In this case, these support modules 9 may be formed as a plate-shaped frame 9a and arranged edgewise, have a cross-sectional size of the passage 2 approximately corresponding through hole 11 and be offset by the length L1 of the strand longitudinal section 3a in the longitudinal direction 2a. The cutting device 4 is arranged offset with respect to the notching device 5 in the passage direction 2a by the distance.

To fix the or the at least two carrier modules 9 on the slider S is a simplified in Fig. 1 illustrated connecting device 12, with which the carrier module 9 preferably by a transverse mounting movement, for. B. from above (not shown) or from one of the two horizontal sides (shown) on the carriage S mountable and disassembled again for disassembly, in each case the carrier module 9 with the notching device 5 and the cutting device 4 with a preassemblable modular unit 32nd can form, which can be mounted and disassembled either in the device 1.

In the drawing figures, the connecting device 12 is connected by a quick connection, z. B. by a connector 13, with a side to a side or upwardly open jack or plug recess formed, in which the carrier module 9 is inserted from the respective side and secured by a releasable securing element. 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. 7, for a plurality of such carrier modules 9 in the passage direction 2a in z. B. equal distances c, to be arranged one behind the other, so that the strand 3 can be slotted and cut in several successively arranged levels. Preferably, the movement control of the notching devices 5 and the cutting devices 4 is arranged so that all the notching devices 5 and all the cutting wires 4a are moved simultaneously. Since the carrier modules 9 are formed substantially the same, only one carrier module 9 needs to be described.

As can be seen in particular from FIG. 2, the carrier module 9 is formed by a plate-shaped frame 9a, 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 largest strand cross section.

The notching device 5 has notches 6 on all peripheral sides, z. B. four notching strips 6 and 6a, 6b, 6c, 6d, which extend on all four sides of the passage 2 across the entire respective side of the passage 2 in a common transverse plane El (Fig. 6) perpendicular to the central axis 2b the passage 2 is. The notching strips 6 are each adjustable transversely to the passage 2 by a push and pull drive 7 illustrated in FIG. 1 to 4 as a double arrow. The push and pull drives 7 can each z. B. be formed by a spindle drive or by a hydraulic cylinder with an off and retractable push and pull rod. In this case, the notching strips 6 each consist of a release position in which a notch 6e located on its inner edge is at a distance from the strand 3 or at a relevant cross-sectional dimension of the passage 2 (FIG. 1), in the direction of the passage 2 into a recess Notch position displaceable, in which the notch 6e is pressed by a predetermined notch depth t in the strand 3. The notched ridges 6e each have the desired, preferably wedge-shaped, notch contour or the desired, in particular wedge-shaped, notch angle.

As already mentioned, the notching device 5 in the context of the invention can have fewer than four notching strips 6e, with no notching strip 6 being present on one or more corresponding sides. Fig. 2a shows an example of a notching device with three notching strips 6b, 6c, 6d, which are formed by two lateral and one upper notching strip. At the bottom of the passage 2 is no score available. In such an embodiment, the ends of the existing notching strips 6, which face the unoccupied side, are formed so long that they at least cover the associated side of the strand 3, wherein these free ends of the notching strips 6, the side of them Can project beyond strand 3. In the exemplary embodiment according to FIG. 2 a, in which the lower notching strip 6 a is missing, the notching strips 6 b, 6 d extend at least up to the upper side of support sections 57 on which the strand 3 rests and is conveyed through the passage 2. Preferably, the notched strips 6b, 6d project beyond the upper side of the support sections 57 and thus also the strand 3 downwards.

In the context of the invention, the guiding and supporting elements 8a, 8b, 8c for a missing notching strip 6a may or may not be arranged on the associated carrier 9a. In the former case, the notched bar 6a is optionally mountable and removable.

Since the notching strips 6 are of the same design and with respect to the passage 2 are arranged the same and are simultaneously displaceable by the associated push and pull drive 7, a description of the remaining notching strips 6 can be omitted in detail for the sake of simplicity.

The strand 3 can always have the same cross-sectional dimension or different cross-sectional dimensions, wherein the cross-sectional shape of the strand 3 is preferably rectangular or square. However, other cross-sectional shapes are also possible within the scope of the invention. It is also desirable in many applications to have a rectangular or square cross-sectional shape with rounded corners for the strand 3. In such a configuration, the notched ridges 6e in the rounded corner region are preferably also correspondingly rounded, which will be described with reference to FIG. 4.

For transverse movement guidance of the notched strips 6a to 6d, a guide device 8 is provided in each case, which includes an acute angle Wl with the vertical or horizontal, which is preferably about 30 ° to 60 °, in particular about 45 °. In this case, the guide devices 8-viewed in the longitudinal direction of the conveyor passage 3-are arranged obliquely in the same circumferential direction, so that the guide directions of the respectively opposite guide projection directions are directed parallel to each other or aligned with each other. The guide devices 8 with the notching strips 6 are mounted on the frame 9a, which is preferably disc-shaped, in order to achieve a relatively small or short dimension in the longitudinal direction. In a disk-shaped frame 9a, the notching devices 5 are thus arranged at one of its broad sides, z. B. at the rear or to the extruder directed broadside. The transverse shape of the frame 9a may preferably also be rectangular or square.

The guide device 8 is formed in the present exemplary embodiments by at least one, in particular plate-shaped, guide slide 8a, which is mounted on the frame 9a on the wide side and is connected to the center line 2b facing inner edge with the associated notched strip 6 and carries them.

The slider 8a may extend vertically with respect to the upper and lower score bars 6a, 6c and horizontally with respect to the lateral score bars 6b, 6d in a vertical and horizontal guide direction, respectively. In an oblique Bewegungsfuhrung the slide 8a extends obliquely thereto.

The particular straight extending guide is formed between the slide 8a and the frame 9a and effective. In the exemplary embodiment, the guide is formed by guiding elements disposed between the slider 8a and the frame 9a on both sides of the longitudinal axis of the respective slider 8a and engaged with each other. Such a pair of guides or two guide pairs (shown) arranged parallel to each other, can or may in each case by at least one guide pin 8b on the one guide member, for. B. on the frame 9 a, formed, which extends into an associated guide groove 8 c in the other guide part. The guide pins 8b may be formed by cross-sectionally preferably round guide pins, wherein on the longer side of the slide axis, an elongate guide pin or two spaced from each other

Guide pin 8b may be present. But it can also be provided other guide elements or guides, eg recirculating ball bearings. The illustrated in Fig. 1 and 2 by double arrows thrust and traction drives 7 may be supported on the frame 9a, and they engage the associated slide 8a, in particular in its associated notched bar 6 end portion facing away.

In the present embodiments, all four notching strips 6 are adapted with respect to their transversely to the passage 2 extending length to the transverse dimensions of the strand 3 that they press in their notch positions a circumferential notch 5a in the strand 3, as shown in Figure 2. Fig. 1 shows the notching strips 6 in their retracted and the strand 3 releasing release position in which the notched ridges 6e are each arranged in an outwardly directed distance from the strand 3 and of a corresponding transverse dimension of the passage 2.

3, the notched ledges 6a to 6d are formed so long in the respective corner region of the square notched bar set that they respectively overlap the adjacent notched bar bar extending at least in the region of the notch leg 6e of the adjacent notched bar, wherein the adjacent notched strip has a recess 6f extending in the common notch strip plane on its end face facing one notched bar whose cross-sectional shape corresponds to and matches the cross-sectional shape of the notch leg 6e, such that the surfaces of the notch leg 6e and the cutout 6f abut one another ,

Preferably, the one notched bar overlaps the adjacent notched bar approximately completely, the recess 6f extending over the entire transverse dimension of the adjacent notched bar.

This overlapping notching bar arrangement in the corner areas of the notch bar set is identical in all corners, but the overlap is arranged rotated from corner area to corner area in the circumferential direction by 90 °. That is, the overlapping direction with which one score bar overlaps the adjacent score line is directed in the same circumferential direction in all corner areas.

This embodiment of the notched bars 6 or the notched bar set allows a transverse movement of the notched bars 6 around the notch stroke, the z. B. the dimensions of Release distance in Fig. 1 plus the notch depth t includes, with an equal and simultaneous movement of the notching strips 6, the system of notches in the corner area is maintained, so that no notch material can get between the notching strips 6 when notching. In this preferably planar system, the relevant notch 6e fills the recess 6f. In this case, the flank surfaces 6g of the overlapped notch 6e run out on the flank surfaces 6g of the overlapping notch 6e. In a limited by the notching strips 6 rectangular cross-sectional shape of the outlet of the flank surfaces 6g of the overlapped notch 6e in Fig. 1 as an oblique edge 6h visible. This is not a miter bevel, but a resulting outlet of the flank surface 6g of the overlapped notch 6e.

If a rectangular cross-sectional shape for the strand 3 is to be realized with rounded corners, as shown as an exemplary embodiment in Fig. 4, the overlapping facing end portions of the notched ridges 6e of the overlapped

Notching strips in the direction opposite to the overlapping direction, forming the rounding of the corner and offset in the direction opposite to the overlapping direction, leak at the flank surfaces 6g of the overlapping notching strip 6e. This outlet is visible in FIG. 4 at horizontally or vertically extending outlet edges 6i, which enclose an angle W2 of approximately 90 ° with respect to the associated horizontal or vertical.

The embodiment of FIG. 5 and 6 differs from the above-described embodiments, inter alia, by other embodiments for the push and pull drives 7. In this embodiment, a transmission 51 is in each case between the associated notching strip 6a to 6d or the associated guide slide 8a, a drive movement, directed in a circumferential direction of the passage 3 and illustrated as a double arrow 52, of an associated base element 53 converts into a notch movement and retraction movement directed transversely to the longitudinal axis 2b of the passage 2. Such a transmission 51 can be realized in different constructions. In the exemplary embodiment, the guide slide 8a is so articulated by a drive element 54 in the form of a connecting rod 54a with the base member 53 that in the initial position of the guided in the circumferential direction movable base member 53, the connecting rod 54a in a with respect to the guide direction of the guide slide 8a oblique starting position is pivoted into a notch position, in which the connecting rod 54a is pivoted in a position approaching the guide direction or this corresponding position. The notch guide extending in the circumferential direction is designated by 50.

Such a gear 51 is not only of small and simple construction, which can be integrated easily, but it also leads to a movement control for the associated notching strip 6, wherein the movement speed is reduced with increasing displacement in the notch direction and the effective = notch force is increased because the connecting rod 54a and the drive member 54 form a toggle mechanism.

The drive elements 54 of all notching strips 6 are preferably mechanically connected to one another in the circumferential direction. Thereby, it is possible to provide a common drive motor 55 for moving all the drive elements 54 and notching ledges 6a to 6d, thereby simplifying the construction and control and reducing the space required for the drive.

The directed in the circumferential direction connection of all drive elements 54 is formed in the exemplary embodiment by an annular drive body 53a, in particular in the form of a closed ring on which the drive motor 55 can sekantial or tangentially attack, as shown by a drive motor 55 clarifying double arrow 52 , To connect the drive motor 55, a connecting piece 53 b can protrude, for. B. radially outward, with which the drive motor 55 may be connected by a hinge 53c.

To guide the annular drive body 53a is a ring guide, which is formed in the exemplary embodiment by at least three or four guide rollers 56 which are rotatably mounted on the circumference on the frame 9a and the drive body 53a at its outer edge (shown) or inner edge (not shown ) and lead in the circumferential direction. The guide rollers 56 preferably have an annular groove in its lateral surface, in which the edge, z. B. the outer edge of the drive ring 53 a is guided. In the region of the carrier module 9, a plate-shaped support member 57 is provided in a horizontal arrangement, on which rest the strand 3 and can be supported by sliding. The support member 57 may be attached to or preferably on the lower edge of the through hole 11, wherein it is z. B. located next to the lower notch bar 6a.

To simplify the production and the assembly or disassembly, it is particularly advantageous in a device 1 with several along the passage 2 successively arranged support modules 9 to connect them preferably detachable by a Aufhahmevorrichtung 31 to the modular unit 32, through the connecting device 12 with the Slider S connectable and thus it can be mounted and disassembled or replaced, preferably by a transverse to the passage 2, in particular horizontally directed assembly or disassembly movement.

The Aufhahmevorrichtung 31 has at least two arranged on opposite sides and parallel to the passage 2 extending Aufhahmestangen 33 on which the carrier modules 9 with therein, for. B. below, arranged matching Aufhahrnelöchern 34 are attached. Preferably, to increase the stability of the module assembly 32 more than two, z. B. three or four, Aufhahme- rods 33 three or four square distributed, which extend through Aufhahme- holes 34, which are preferably arranged in the upper and lower region of the or the carrier modules 9. In the present exemplary embodiments three or four Aufhahmestangen 33 are provided which extend through Aufhahmelöcher 34 which are arranged in the corner regions of the or the carrier modules 9, z. The distance f (FIG. 6) between the receiving bars 33, which extends transversely to the passage 2 and transversely to the cutting wires 4a, is greater than the spacing of the cutting wires 4a in their two cut end positions, so that the Aufhahmestangen 33 are located outside the cutting area or passage 2 and this does not interfere.

The carrier modules 9 can by arranged on the connecting rods 33 spacers, for. B. spacers to be held at a longitudinal distance from each other. The module assembly 32 is pre-assembled with carrier modules 9 optional number, so that a desired prefabricated modular unit 32 can be mounted quickly. In this case, the desired handling-friendly and rapid disassembly and / or assembly by the connecting device 12 in the form of a quick-release connection, in particular in the form of a connector 13, can be achieved.

In one or more carrier modules 9 arranged behind each other, two connecting devices 12 arranged one behind the other on both sides of the passage 2 are provided in order to increase the stability of the attachment.

The slider S associated connection parts, for. B. bearing blocks, the connecting device 12 are designated 12a, and the module assembly 32 associated connecting parts are denoted by 12b.

The existing in the exemplary embodiments connector 13 is formed in each case by a jack or plug-in recess 13a in the one connecting part and a plug-in pin 13b in the other connecting part. For example, according to FIG. 7, the plug recess 13a can be arranged in the slide-side connection parts 12a and preferably laterally open, wherein the module-side connection parts 12b can be formed by the connecting rods 33, for example by the end regions of the connecting rods 33 which are fittingly received in the plug-in recesses 13a are.

B. facing each other, and abut which corresponding module-side positioning surfaces 39 b. The result is a simple and cost-producible construction, when the positioning surfaces 39a are formed by transversely arranged side surfaces of the plug-in recesses 13a and thus the corresponding positioning surfaces 39b are formed by the end faces of the Aufhahmestangen 33.

The longitudinal distance h between the positioning surfaces 39a may thus correspond to the length L2 of the receiving bars 33. For fixing against an unwanted return movement, one or more securing elements 13c may serve, which in principle are embodied in the exemplary embodiment according to FIG. 7 and in the form of a device to be described, as shown in FIGS. 8 to 11.
