Description

The invention relates to a taffeta unit for a taffeta machine and a taffeta machine with such a taffeta unit.

For sports floors, such as those used for football fields, natural turf has long been used. However, this is very intensive care and tends to develop damage at high loads. For this reason artificial turf pitches have been developed, which are no longer based on natural grass, but in which an artificial material mimics the properties of grass.

Furthermore, there has been a mixture of natural and artificial turf for some time, in which case first a natural turf is applied, which is then reinforced by yarn sections made of plastic. Thus, the usual properties of a natural grass can be better preserved, at the same time the resistance to damage is significantly increased compared to pure natural grass. Furthermore, the maintenance effort is reduced.

The insertion of such yarn sections into a substrate in which the natural turf is typically formed is referred to as tearing. Typically, suitably cut yarn sections are inserted from above into the ground, so that they are only partially buried in the ground and partially stand up out of the ground. In this respect, the upwardly projecting parts of the yarn sections behave very similar to natural blades of grass. It is understood that for a typical sports field, which may for example have the size of a conventional football field, a very large number of yarn sections must be introduced into the ground. It is almost mandatory that this is done by machine. Accordingly, corresponding taffeta machines have already been developed.

An exemplary taffeta machine can handle the document DE 601 11 738 T2 be removed. In doing so, the fibers are blown into a suitable operating position with the aid of air, where they are subsequently cut off and inserted into the substrate. Another exemplary taffeta machine may be the document EP 0 610 352 D1 are taken. Here, fibers are brought by means of tubes in a transfer position, from which they are then inserted into the ground.

However, it has been found that, in known taffeta machines, the mechanisms which insert such a plurality of yarn sections into the substrate are very complicated to manufacture and are also prone to maintenance.

It is therefore an object of the invention to provide a tare unit, which can be operated alternatively, for example, with a lower disturbance potential and / or with a lower maintenance. It is further an object of the invention to provide a taffeta machine with such a tare unit.

This is achieved according to the invention by a taffeta unit and a taffeta machine according to the respective main claims. Advantageous embodiments are claimed, for example, in the respective subclaims.

1 shows a taffeta machine 10 according to an embodiment of the invention. The taffeta machine 10 has a frame 15 which ensures fundamental stability and to which the components described below are attached.

The taffeta machine 10 has a tare unit 100 on. This serves to insert yarn sections into a substrate on which the taffeta machine 10 moves. This will be described later in the description, in particular with reference to 2 ff, will be discussed in detail.

To supply the taffeta unit 100 with yarn strands, the Taftmaschine points 10 a plurality of coils 20 on. On every spool 20 In this case, a respective yarn strand is wound, which is the taffeta unit 100 for insertion into the ground on which the taffeta machine 10 moved, is supplied.

The taffeta machine 10 is presently designed to be in the in 1 to turn left, or in the opposite direction. As can be seen are - seen in the direction of travel - the coils 20 on only one side of the taffeta unit 100 , This causes the tether unit 100 adjacent to a longitudinal end or in an end quarter of the longitudinal extension of the taffeta machine 10 arrange, as is the case in the embodiment shown here.

This brings with it the advantage that the taffeta machine 10 on one side - seen in the direction of travel - only a little above the taffeta unit 100 also available. This reduces the space occupied by the taffeta machine 10 needed to the taffeta unit 100 to spend a certain position. This has proven to be particularly advantageous in typical sports fields such as football fields, as they are often limited by banners or similar enclosures, which are located immediately adjacent to a playing field. The room which the taffeta machine 10 can go beyond the field to the entire playing field with the taffeta unit 100 to edit is considerably limited. Due to the present embodiment, however, a complete processing of the field is also possible in such situations.

The taffeta machine 10 has a drive unit 40 on. This is in the present case designed in the form of an internal combustion engine and serves to supply energy and the propulsion of the taffeta machine 10 ,

To drive the taffeta machine 10 this has in the embodiment shown here a present pendulum mounted tracked chassis 50 on. This is executed in this case two lanes. Furthermore, the taffeta machine 10 a front steering gear 55 on, which in the present case is formed from a plurality of pneumatic wheels, to the surface pressure in the front part of the taffeta machine 10 to reduce. By means of the steering gear 55 can the direction of movement of the taffeta machine 10 be specified.

On the steering gear 55 Furthermore, in the present case is a height-adjustable front pressure roller 57 appropriate. This serves to further reduce the surface pressure and to level the ground. The taftende soil is thus without disturbing bumps or with less disturbing bumps on the taffeta unit 100 to hand over.

The taffeta unit 100 In the present case, it is guided by means of an integrated button unit just above the ground with a respectively set or adjustable tab height. The button unit scans the soil continuously and ensures that the jaded yarn is just incorporated. The button unit can be designed, for example, as a roll, which rests on the floor and which thus senses the height. However, it can also be embodied, for example, electronically and / or sensorily, for example by means of a radar sensor, an ultrasonic sensor or a camera.

Furthermore, the taffeta machine 10 in this case, a tread plate 60 on. This hangs just above the ground to facilitate the view of the yarn already flooded.

In addition, the taffeta machine points 10 in this case, a rear pressure roller 70 on. This is height adjustable and serves the tracks of the previous tracked chassis 50 to equalize.

The taffeta machine 10 may also have a working space in which an operator can sit or stand to the taffeta machine 10 to operate and / or control.

It should be understood that the taffeta machine described herein 10 represents an advantageous, but not the only possible execution. In particular, it should be noted that the components described, apart from the taffeta unit 100 , are optional and do not necessarily have to be present or not necessarily in the embodiment described here must be present in order to fulfill the functionality of a Taftmaschine. It may also be present only some of the components described, these may be made entirely or partially different and there may be other components. All such combinations are considered part of the disclosure of this application.

2 shows a part of the taffeta unit 100 , which in the in 1 shown taffeta machine 10 is installed. It is thus in particular also a Tafteinheit according to an embodiment of the invention.

It should be mentioned that by means of the taffeta machine described here 10 or with the tapping unit described here 100 In particular, a method according to the invention can also be carried out. This can be done in particular as will be described below.

The taffeta unit 100 is adapted to a number or plurality of yarn strands 110 to pick up, cut up and place in the ground. It should be understood that in the illustration of 2 in which it is a side view, only such a skein 110 is visible. The other yarn strands 110 are immediately behind it.

The taffeta unit 100 has a yarn transport device 200 which is adapted to the yarn strands 110 take up and transport, as will be described below.

The yarn transporting device 200 has a first role 201 and a second role 202 on. The first role 201 is a driven roller, ie it can be actively put into a rotary motion. This can, for example, directly from the drive device 40 can be derived, or it can also be generated by its own drive such as an electric motor.

The yarn transporting device 200 has a plurality of yarn grippers 220 on. These are designed to selectively yarn strands 110 to hold or release. For this they can be opened and closed. This will be described in more detail below.

The yarn gripper 220 are along an orbit 205 arranged. This leads to the two roles 201 . 202 around. The orbit 205 has a flat bottom. The orbit 205 points to the places where the rollers 201 . 202 their respective maximum vertical extent also have their maximum vertical extent. Between the roles 201 . 202 , in the middle between the rollers 201 . 202 , indicates the orbit 205 their lowest vertical extent. Since at this point further, vertically extending components are present, which are described below, this formation of the orbit leads to a smaller vertical extension or height of the tare unit 100 ,

The yarn gripper 220 run along the orbit 205 in a given direction of rotation, which by the direction of rotation of the first roll 201 is determined. The direction of rotation is in the present case such that the yarn gripper 210 Move top left and bottom right. This applies to the view of 2 ,

The yarn transporting device 200 is designed to thread strands 110 at a pick-up point 207 take. For this purpose, guideways or opener and closer tracks are provided, with which the yarn gripper 220 can be opened and closed. Thereby the yarn grippers become 220 immediately before the pick-up point 207 kept open so that the yarn strands 110 can be recorded, and are immediately at the pick-up point 207 closed so that the yarn strands 110 guided by the yarn grippers and transported earth.

The yarn gripper 220 are presently interconnected as an infinite chain (gripper chain) by means of bolts.

As in 2 to recognize is a recorded yarn strand 110 along the top of the guideway 205 transported to the left. As a result, it enters a yarn segment transport unit 210 , Under such a yarn section transport unit 210 is a number of yarn grippers 220 to understand which along the orbit 205 are arranged adjacent and which receive a length of the yarns, which corresponds to a yarn section which is to be inserted into the substrate. It should be understood, however, that such a yarn section transport unit 210 is not necessarily recognizable by optical, technical or other features, especially in the absence of yarn strands 110 ,

To the yarn strands 110 to cut is a cutting unit 240 intended. This is in the present case designed as a heating element, so that the cutting takes place by the action of heat. However, it could also be designed as a knife, for example. The cutting unit 240 is designed to thread strands 110 so to cut that one between the roles 201 . 202 at the top of the orbit 205 cut yarn section 212 remains. This yarn section 212 is intended for insertion into the ground.

It should be noted that it is the front and rear Garngreifern 230 . 235 only to those of the yarn gripper 220 act, which end of the Garnabschnitttransportinheit 210 are located. They are otherwise normal yarn grippers 220 ,

The position of the cutting unit 240 is presently adjustable, in the present case three positions, which in 2 are marked with P1, P2, P3. The concrete possible positions of the cutting unit 240 are on the right side of 2 shown. For this purpose correspond to end points of the yarn section shown on the left side 212 , which are provided with corresponding designations P1, P2, P3. It should be understood that more or less positions or a stepless adjustability are possible.

Due to the adjustable cutting unit 240 can be the length of the yarn section 212 be set. Accordingly, the length of the Garnabschnitttransportinheit also fits 210 at. Accordingly, the feed, so the movement of the yarn section 212 adjusted to the central position. For this purpose, in particular a rotary encoder can be used. As advantageously adjustable lengths of the yarn section, which by appropriate adjustment of the cutting unit 240 can be achieved, for example, 240 mm, 320 mm and 400 mm to call.

The taffeta unit 100 also has a number of insertion elements 250 on. These are in the present case designed as Taftnadel, wherein in the view of 2 only one such Taftnadel is to be seen, the others are directly behind it.

The insert element 250 is centered between the two rolls as shown 201 . 202 and immediately above the vertical thinnest point of the orbit 205 arranged. The taffeta needle is vertically aligned.

When the yarn gripper 220 and the yarn section 212 in the 2 shown state can be the insertion element 250 are moved straight down, where it is the respectively associated yarn section 212 takes along, through two gaps between yarn grippers 220 penetrates, so twice the orbit 205 crosses, and the yarn section 212 then used in the underground. For this purpose, the insertion moves 250 vertically straight down.

To stabilize the insertion element 250 has the taffeta unit 100 a needle guide 280 and a needle plate 285 on. The needle guide 280 is above the revolving ban 205 and will be described further below.

The taffeta unit 100 also has a bottom plate 120 on. This is on the bottom side of the taffeta unit 100 arranged and also for each insert element 250 a respective vertical through hole. The bottom plate 120 in particular serves to protect the taffeta unit 100 from mechanical damage and from contamination. In particular, it has the task of pulling up not yet grown turf when booting the Einsetzelemente 250 to avoid.

3 shows the taffeta unit from below. It can be seen that a total of 10 insertion elements 250 are arranged side by side, which through corresponding holes or recesses in the bottom plate 120 can pierce down. Otherwise, please refer to the description of the components 2 directed.

The 4 to 6 show the already mentioned needle guide 280 in greater detail. Show 4 a view from below, 5 a side view and 6 another side view.

The needle guide 280 has a first arm 281 and an opposite second arm 282 on. The first arm 281 is with a first guide plate 283 connected and the second arm 283 is with a second guide plate 284 connected. In the guide plates 283 . 284 each U-shaped recesses are formed, each insertion element 250 through a U-shaped recess in the first guide plate 283 and by a U-shaped recess in the second guide plate 284 passes. Through the recesses, the respective insert element 250 guided in an advantageous manner, which avoids jamming or other malfunction. By the U-shaped design ensures that any entrained soil or other contaminants do not lead to a blockage of a bore, but can fall off the side of the recess.

The two guide plates 283 . 284 are by means of fastening screws 286 on the arms 281 . 282 attached. By loosening these fixing screws 286 they are adjustable in a horizontal plane. Furthermore, there are also adjusting screws 287 provided, with which an adjustment in the Y direction is possible. The adjustment in the X direction can be done by looking at the guide plates 283 . 284 pull something out by hand and then the fixing screws 286 Attracts again.

Furthermore, locknuts 288 and adjusting screws 289 intended. This can be the height of the orbit 205 be set. For this purpose, the lock nuts 288 loosened and fixed again after adjustment.

The orbit 205 is present in the middle flat to the tension in the yarn strand 110 to increase in the middle. Thus, the yarn becomes optimally in an insertion element 250 guided.

The 7 . 8th and 9 show the interaction between a cam 130 and movable sectors 140 from the already mentioned above opener and closer tracks. It should be understood that the device shown revolves around 135 is movable, especially if by means of the control cam 130 a corresponding force is exercised. The movements are described below.

The 10 . 11 . 12 . 13 show the insertion elements 250 , These are on a needle clamp 270 attached, which in turn to a needle carrier 260 is attached. This allows the insertion elements 250 be moved vertically up and down, as already described above with respect to 2 has been described.

On the needle carrier 260 is a control 265 attached, which with the just described control curve 130 interacts. This will be described further below. The control 265 follows any vertical movement of the needle carrier 260 ,

It should be mentioned that from 10 an embodiment is shown in which more than 10 inserting elements 250 , 88 inserting elements in the present case 250 are shown. The corresponding scaling is easy to execute. It should be understood that in principle any other number of insertion elements 250 can be used.

The 14 to 19 each show one or two yarn grippers 220 in an open state. The 20 to 25 each show one or two yarn grippers 220 in a closed state.

Each yarn grab 220 has a sliding profile 224 and a counter-profile 226 on. While the counterhold profiles 226 in a direction transverse to the orbit are not displaced, are the sliding profiles 224 displaceable in this direction. To trigger such a shift serve lateral conditioning elements 228 . 229 , Which are designed here as rollers. The investment elements 228 . 229 lie against the opening or closing track, so that the position of the sliding profiles 224 relative to the counterhold profiles 226 can be changed.

By changing the positions of the two profiles 224 . 226 yarn strands can be relative to each other 110 be clamped and released. These are edges of the sliding profiles 224 , which with edges of the counterhold profiles 226 cooperate, obliquely executed, ie they are to orbit 205 something tilted. This ensures that the yarn strands 110 be clamped at defined positions.

In the 26 to 35 are states of the taffeta unit 100 shown which occur during a taffeta process. The show 26 . 28 . 30 . 32 . 34 respective side views and the 27 . 29 . 31 . 33 . 35 respective other side views. The 26 . 27 show a first state. The 28 . 29 show a second state. The 30 . 31 show a third state. The 32 . 33 show a fourth state. The 34 . 35 show a fifth state.

With regard to the elements shown, reference is made to the description already made.

The first state corresponds to a starting position, in which the needle carrier 260 is up. The movable sectors 140 are in a state in which the yarn gripper 220 are in a closed state.

The second state became the needle carrier 260 already drove down a bit. This is especially true of the insert element 250 and on the control 265 recognizable. The inserter 250 starts the yarn section 212 to grab. The yarn gripper 220 are still closed.

The third condition became the needle carrier 260 even further down. Through the shown interaction of the also further down driven control 265 and the control curve 130 become the movable sectors 140 pivoted laterally and the yarn gripper 220 which the yarn section 212 keep open. The insert element 250 can thus the yarn section 212 press down.

The fourth state is the needle carrier 260 in its lowest position. The insert element 250 is partially underground in the taffeta unit 100 , The control 265 is outside the control curve 130 , where the movable sectors 140 stay in position due to friction. The yarn gripper 220 stay open.

The fifth state is the needle carrier 260 back in its upper position. Accordingly, the control is also 265 moved up and over the control curve 130 made sure that the yarn gripper 220 be closed again. However, these no longer hold a yarn section at the moment because it has been transported downwards through the process just described into the underground and remains there.

It should be noted that with the yarn grippers just described with reference to the individual states 220 in particular those yarn grippers 220 are meant which a respective yarn section to be used 212 hold. These can thus be independent of any movement along the orbit 205 be opened and closed.
