Definitions
- the invention relates to a device according to the preamble of claim 1, 21 and 29.
- the notching device comprises a plurality of vertical notching strips, which are arranged on a side wall, an angle wall with a horizontal wall leg and a vertical wall leg and a plurality of bottom strips.
- Strangabitess takes place in several steps.
- a transported Tonstrangl Kunststoffsabêt is stopped, and the side wall is moved with the vertical notching strips laterally against the Clay section and moved so far until the Clay section is located in a arranged next to the previous conveyor section position on the vertical wall leg and under the horizontal wall leg , By applying lateral pressure to the sidewall, the clay strand portion is notched on both opposite sides.
- a second notching process the lower and upper sides of the cladding section are notched between the floor slats and the horizontal wall limb.
- This known device is not only complicated in terms of design and process, because the notching is done in two notching operations, but it is also of a large construction, which is required for notching to shift the clay strand section transversely to the conveying passage, which is undesirable or not in many manufacturing facilities is possible.
- there is a risk of poor notching and cutting quality because it is difficult to place the notches in a common plane and with a time delay in the cutting plane.
- the invention has for its object to improve a device of the type specified with respect to the notching device. In particular, the time required for scoring should be shortened. It is also a lateral movement of the clay strand can be avoided and it is also desirable to achieve a favorable load on the clay strand during notches.
- the invention is based on the finding that a notching of the clay strand in several consecutive notching steps not only an unfavorable load on the clay strand is exercised, but also leads to a difficult construction and control of the notch components.
- Notched strips mounted independently of each other and from a release position in an offset to the central axis of the conveyor passage notched position and moved back again.
- two opposing Kerbleisten, z. B. two laterally opposed or two superimposed notched strips or all notches, simultaneously be movable in their notch position.
- the notched strips can be due to their independent arrangement and movement opposite each other and preferably simultaneously move for a notching process against the clays. This makes it possible to achieve a clean circumferential notch and a clean cut.
- the preferably simultaneous movement of the notching strips can be carried out in a simple manner, in particular, if in each case two adjacent end regions of the notching strips have miter bevels limiting the free spaces in the region of which the notching strips can move into their notched positions and in the notch position on the miter bevels Can form movement stop. Since it is to be expected that accumulates clay material between the miter bevels, it is advantageous at least in one of the miter surface of
- the notching strips are located in a common transverse plane, wherein they are mounted independently of one another and are movable transversely to the conveying passage.
- the device or their notching device in such a way that the notching strips stabilize in their holder at least in the notch position.
- This object is achieved by the features of claim 14, wherein at least in one corner of the frame-shaped notched strips, the facing ends of two adjacent notching strips in their notch form fit into each other and thereby supported in the longitudinal direction of the conveying passage to each other and thereby stabilized.
- the existing notch webs are excellently, each bordering in a recess corresponding cross-sectional shape least in the notch of the adjacent notch strip.
- the recess is particularly advantageous for the recess to be elongate, in particular continuous, in each case in the longitudinal direction of the associated notch.
- This configuration makes it possible to adjust the recess strip having a notching strip transversely to the passage axis and thereby adapt this notch strip to different cross-sectional dimensions of the strand to be notched. Depending on the arrangement of the notching strips this adjustment can be made horizontally or vertically.
- the device or the notching device with an adjusting device, which makes it possible to adjust the adjustable notching strip with respect to their release position and to position, being from this positioned release position in the notch position and moved back again.
- the invention also relates to the device or the notching device in such a way that horizontally and / or vertically opposite notching strips are adjustable with respect to their release position and thus adjustable to different cross-sectional dimensions of the strand.
- a horizontal and vertical adjustability can be achieved in that the notched strips overlap in each case at one end the adjacent notch strip and are overlapped at the other end of the notch strip adjacent thereto, wherein all notching not only transversely to the passage axis, but also in each case in their longitudinal direction, ie in the circumferential direction of the passage, are movable and adjustable by an adjusting device.
- the invention is further based on the object to simplify a device according to the preamble of claim 21. This simplification is intended to affect in particular both the construction and the motion control.
- This embodiment allows a substantial simplification of the construction and the drive.
- the separation process can be done when notching the notch strips or in their notch position, whereby a rational operation is achieved, which also allows a clean cut.
- a prescribed combination of the processes notches and cutting or separating can thereby further rationalize production and simplify the design, if several notching and cutting devices are arranged in the longitudinal direction of the passage one behind the other, preferably notched and cut simultaneously.
- the notch roller is formed by two pulley discs which are axially spaced from each other, the cutting wire extending between the pulley discs and intersecting the central portion of the pulley discs. In this device, cutting takes place continuously during notching. This not only reduces the processing time, but the device is also of a small
- the cutting wire is effective in the bow area where the associated roller discs dip into the clay cord and mold the notch. Since the cutting wire is always located in the middle of the roller discs, it is not only always centered in the notch, but it is also its leadership continuously ensured. In addition, during cutting, the notch is continuously formed and stabilized by the roll bow portions always present in front of and behind the cutting wire. Thus, not only a clean notch but also a clean cut is achieved, with the notch perimeter sections and the cut in the common transverse plane being in line with each other.
- the embodiment according to the invention can be combined with conventional notching and chamfering devices arranged on adjacent sides of the conveying passage in order to obtain a clean cut also on these sides.
- the inventive design also makes it possible to form arranged on both sides of the conveyor passage notch roll holder as a holder for the cutting wire, so that they form the cutting device with the cutting wire.

- roller discs 23a, 23b are arranged at an axial distance e from each other which is equal to or taking into account a movement clearance larger than the cross-sectional dimension of the cutting wire 13, which therefore not only between the roller discs 23a, 23b of both notch rollers 23 has room, but the roller discs 23a , 23b define the cutting wire 13 with their sides facing each other, whereby the cutting wire 13 receives a guide and is stabilized.
- roller discs 23a, 23b have on their circumference the desired notch contour or the desired notch angle.
- the cutting wire 13 may extend through channels disposed therein when it is to extend further to an associated cutting device.
- the cutting wire 13 may also extend radially adjacent to the axles 24 or shafts. It is essential that the cutting wire extends in the central region of the roller discs 23a, 23b and crosses the circumference of the roller discs 23a, 23b in the bow portion B, in which the roller discs 23a, 23b dip into the clay cord 2 during notches.
- the roll holder 22 can also form holding and guiding parts for the cutting wire 13 and thus form the cutting device in this regard.
- the notching device 21 is thus combined with the cutting device, so that it is possible to simultaneously score and cut the clay strand.
- the cut direction illustrated by a double arrow may be vertical (Fig. 26) or horizontal (Fig. 28).
- the roll holders 22 and notching rolls 23 are in a lateral position with respect to the clay strand 2 or the conveying passage 3.
- these parts are located above and below the clay strand 2 or conveying passage 3.
- the notching device 21 is moved with the cutting wire 13 for notching each from one side of the clay strand 2 and conveying passage 3 to the other side. Therefore, there is no need for movements of the notch rollers 23 between a release position and a notch position on the clay strand 2 to and away from this, as is the case with the notch and Anfasangn 4, 15 of the case.
- the two arranged on opposite sides nicking rollers 23 from a position in which it is with the cutting wire 13 on an other side of the clay strand 2 or conveyor passage 3, moved to the opposite side, wherein the nailing rollers 23rd Immerse the notch depth t in the clay strand 2 and roll with the advance of the notch rollers 23 two opposing notches simultaneously.
- the clay strand 2 is cut with the cutting wire 13 arranged between the roller discs 23a, 23b in the continuous immersion region B.
- a Anfasvorraum 25 with two transversely to the conveyor passage 3 extending chamfers 26a, 26b to be arranged, which have a along the central axis 3a directed distance from each other, which corresponds taking into account the cutting gap d the transverse dimension of the cutting wire 13 with movement play.
- Both Anfasoopn 26 a, 26 b is at least one push and pull drive 5, z. B. in the above sense, associated with which the Anfasangn 26 a, 26 b are movable between their release positions and notch positions, as has been described for the Anfasraun 15.
- the Anfasologicaln 26a, 26b are moved to the formation of an associated bevel in the clay strand 2 against this, before the notch rollers 23 are moved with the cutting wire 13 for performing those notches against the clay strand 2.
- the latter have at their ends inside preferably to the notch shape of the roller discs adapted recesses 26c, through which the roller discs 23a, 23b are movable.
- the slot has at its the
- the notch rollers 23 may or may not be driven at a peripheral speed corresponding to the feed speed at the time of cutting.
- the load on the material of the strand 2 is relatively low because the material does not have to drive the detent rollers 23 with respect to their rolling motion.
- the rotary drive of the notching rollers 23 or roller discs 23a, 23b takes place by a entrainment function of the material.
- a drive 27 for one or each of the scoring rollers 23 may, for. B. have a rack 31 which extends parallel to the cutting direction and by a drive connection, for. B. a gear train 28, with the associated scoring roller 23rd connected is.
- a respective associated electric drive motor for the pick rollers 23 may be provided.
- a notch roller 23 need not be present on each of the opposite sides. This notching device 21 also works when only one notch roller 23 is present with the cutting wire 13 on one side. On the opposite side of the notch device z. B. in place of a nailing roll two more Anjanangn 26 a, 26 b with associated push and pull drives 5 have.
- the movement of the cutting device or cutting wire 13 ( Figures 1 to 18 and 26 to 28) or the cutting units 13 ( Figures 19 and 20) forming a moving unit may be controlled so that the cutting movement of each of the and same side to the other side.
- the one or more cutting wires 13 are thereby moved back after each cut to always cut starting from the same side. This makes it necessary that the cut clay strand 2 after cutting by a spreader must be mechanically moved slightly apart (several mm) to create a gap in which the cutting wire 13 can be moved back without the clay strand 2 or the cut Touching shaping.
- the cutting wire (s) 13 are alternately moved alternately from one side of the clay strand 2 and the conveying passage 3 to the other side and then from this other side to the one side, cutting the clay strand 2.
- the cutting wire or wires 13 are moved with a horizontal cutting direction or vertical cutting direction.
- the cutting wire or wires 13 are preferably arranged in a position inclined with respect to the cutting direction, which is shown schematically in FIGS. 1 and 2.
- the notched surfaces 5c are described as wedge surfaces.
- the notched webs 4a and the chamfer webs 15b may have convexly rounded notched surfaces 4c or beveled surface.
