Background Art

This kind of apparatus is used for generating single-axial fabric or multi-axial fabric. In the case of uniaxial to the fabric to the fabric, the yarn sheet produced by all of the yarns will have the same direction. Then the states the gauze piece is directed through the reinforcing section, which are connected together so as to produce flat structure In this case, the yarn with respect to the conveying device can be of any angle to the conveying direction. In the case of multi-axial fabric, has a plurality of different direction of the yarn sheet stacked up and down, is then LED through the reinforcement section, which is connected with so that the yarn, in order to produce the flat material. In the case of multi-axial fabric, relative to the yarn direction of movement of the conveying device can be, for example, is the angle of 45° and a negative 45°.

In order to be able to produce these fiber bundle, yarn laying device from the delivery device for the yarn of the conveyer belt is LED to the one longitudinal side of the conveying device on the other side of the conveyer belt. Conveying device at a predetermined speed towards the reinforcing sector travel. Conveyer belt travel at the same speed, and supporting the yarn, the yarn on the conveying device between the sagging will not be at the center, and then can be kept relatively equal stress.

However, in some cases, the position of the conveyer belt would interfere with penetration of the yarn In to a conveying device.

Content of the invention

The purpose of this invention lies in, so that the multi-shaft and single-shaft to the fabric to the fabric when the fabric can have a relatively large degree of freedom.

On opening a portion of the said type of device, the realization of the stated purpose in the following manner: between the-oriented at least of the conveying belt of the part of the device can be mobile.

May then be suitably adjusting the position of the conveyer belt, in particular, is the section of the instant-oriented to below for the sake of clear-called "upper"-position, the yarn is laid without any problems, but the yarn is still subject to a certain support, enable to produce and maintain a desired stress.

This is especially suitable for the following information, that is, ranges of the area away from the reinforcing section coursee is arranged on one side of the conveying device. In many cases, desired uniaxial fabric or multi-axial fabric, the fabric is not only in a certain direction with a predetermined tensile strength, and its surface also has the appearance of a pre-given or to the surface is provided with a pre-given appearance. If for example yarn on the surface of the yarn only one single direction, will cause the undesirable visual effect. Coursee conveying yarn conveying device can, for example cutting, slicing, the yarn on a conveyer belt are disorderly arranged. In this case, the conveying device is constructed coursee "slicer". Here also can be delivered, for example, web to unwind from the roller. For coursee result in an increase in a certain thickness, this can be through the conveyer belt of the vertical of the upper section of the shift to be compensated. If the "horizontal direction" and about "vertical direction", these technique language family is used for simplifying the description. "Horizontal" usually means the one or more guided through the yarn the direction of the reinforcing sections. "Vertical direction" is perpendicular to the above-mentioned "horizontal direction", and perpendicular to the width direction of the fabric. If the conveying belt or the upper part of the vertical in the area of the lapping to shimoji shift, the movement space of the adequate for pad gauze device uses, in order to be able to penetrate the yarn in to a conveying device. These yarn therefore in the conveying device is not directly over the conveyor belt, and is disposed on the coursee. However, this also implies that sufficient support.

Facing the conveyor belt to the end of the reinforcing section of the reinforcement is preferably maintained constant with respect to the height position of the section, and other parts of the conveyor belt shift-independent. By ensuring that one or a plurality of yarn can adopt the same always of penetration in a manner in the reinforcement section, and always achieved by way of a can adopt the same reinforcement. The reinforcing section may be, for example, a knitting device, in the in the knitting device, one or a plurality of yarn are connected to each other by a knitting process. In other embodiments, the reinforcing section may also have a heatable roller, for the corresponding terms in the yarn structure, these the roller causes the yarn is bonded each other under a certain pressure. The reinforcing section may also consider other design scheme.

In this preferably, the conveyor belt is guided around the bracket, wherein the bracket with respect to the area of the instant device can be. The bracket thus is composed of a plurality of part or region. The opposite side is located in the area of the bracket can be vertically shift, can be in the region between the different distances apart of the device. Other regions of the support can be kept resting in the vertical direction. The conveyor belt is usually as long as a few meters. The stress applied to the conveyor belt can be infinity, so that even if the area of the can be actually settling, the conveyor belt will also stick to most of the on in the region. Therefore, when the using coursee, can adopt a simple manner the proper adjustment of the position of the conveyer belt, the instant-oriented coursee the top surface of the device relative to the delivery device is in a certain position, so that the ranges can be for the yarn to be inserted in to a conveying device, the conveying device between the yarn, however, is still adequate support.

The area can be of the bracket relative to the lapping keep the same direction of the device, with the region with respect to the lapping independently of the position of the device. The shift is thus, will not be the area of the can be or swing of the gear train, but in order to maintain the same level as in the vertical direction to the sedimentation. This is convenient for motion control.

The bracket preferably has a reinforcing-oriented sector of the sector, the conveyer belt for forming the section of the steering device, said steering device especially constructed into a cutting edge (Messerkante). In operation, the steering device remains stationary in the vertical direction, that is to say, it makes the fiber bundle always along the same direction is transmitted to the reinforcement section, and can be independent of the vertical position of the area. Steering device at the ends of the reinforcing section of the smaller the steering radius of the, the upper section of the conveyor belt and the entrance end of the gap between the sections will be small. The smaller the space, one or more of the yarn under the condition of without support must move through the shorter distance. Steering device also can be configured as a steering roller.

Preferably the conveyor belt in its departure from the end of the reinforcing section is provided with a belt transmission mechanism. At the ends of the reinforcing section from a sufficient mounting space can be available for use. Belt transmission mechanism can be configured, for example, the steering wheel is driven. Also can make the belt transmission mechanism remains stationary in the vertical direction, and can be independent of the vertical position of the area.

Preferably the conveyor belt comprises a shift transmission mechanism, the shift of the transmission mechanism can move away from the reinforcing section of the conveyor belt, or towards the reinforcing sector mobile, wherein the shift transmission mechanism with belt transmission mechanism proper coupling, so that the conveyer belt between the-oriented shift section of the device relative to the instant when the region is maintained stationary. This kind of design is in particular favourable under the following conditions: that is, for example, in order to maintain the aim should be to arrive from the following sides of the reinforcing section, which are one or more from the side of the yarn sheet is transported. In this case, on the whole conveyor belt from the reinforcing sector leave the mobile for example 80 cm, thus riggers can access. But usually wished to avoid in the course of the yarn sheet relative to the reinforcing section is also mobile. If now the upper section of the conveyor belt of the auxiliary mechanism keeps resting in the shift direction, wherein the one or more of the yarn directly or indirectly on the upper section bears against the, in this process is kept to one or more of the support of the yarn sheet, and these fiber bundle is not moved away from the reinforcing section. This point of the above-mentioned support in use under the condition of use can be made for example to realize the following way, in other words through the bracket to shift the shift transmission mechanism. At the same time carries out the operation of the belt drive mechanism, the belt drive mechanism relative to the bracket properly drives the conveyer belt, the conveyer belt to move with respect to the frame at a certain speed to the reinforcement section, the speed and the speed of the move away from the reinforcing section of the same. By this way the upper section of the conveyor belt relative to the one or a plurality of fiber bundle remains stationary.

Yarn laying device preferably has pad gauze , the pad gauze can move in the direction along the three space. Has a plurality of thread guide for guiding a thread the pad gauze , can then in sedimentation to a conveying device, so that the yarn is laid there. In the region of the conveyor belt in the vertical direction relative to the guide device can shift, therefore, it is possible to accurately adjust the conveying belt, so that no pad gauze in a vertical movable.

Description of drawings

By means of a preferred embodiment of the combined Figures to describe the present invention. Shown in the Figure:

Figure 1 is a top view of for generating multi-axial fabric illustrative of the device; and

Figure 2 is a side view of the illustrative of the device.

Mode of execution

Of these Figures are purely illustrative, and non-accurate size. These Figures is only used for introducing the invention.

Figure 1 diagrammatically shown for generating multi-shaft equipment to the fabric to the fabric, the device having two ranges (Legeeinrichtung) 2, 3. Each yarn laying device 2, 3 have pad gauze (Fadenleger) 4, the movably states the pad gauze supported on the hanger (Portal) 5 the upper. Hanger 5 with respect to the conveying direction can be 6 adjusted to different angles. Shown here is the angle position of the 45 °, 90° and a negative 45°. Typically, hanger 5 is set up in the different angular positions, relative to the conveying direction, for example, 6 is the angle of 45° and a negative 45 °, thus pad gauze 4 with respect to the conveying direction can produce 6 is formed or negative 45° angle of 45° of the yarn sheet.

Device 1 with conveyor belt 7, the upper section of the conveyor belt 8 in the conveying direction can be 6 mobile. The conveyor belt 7 of the two longitudinal sides of the external is provided with a conveying device 9, 10, by pad gauze 4 guide the yarn can be inserted in to the delivery device. Conveying device 9, 10 can also be along the delivery direction 6 mobile, to be more precise, with the conveyor belt 7 of the upper section of the 8 moving at the same speed.

Through the conveying device 9, 10 of the upper and lower stacked (Verfestigungsabschnitt) 11 is transmitted to the reinforcement section of the yarn sheet, said reinforcing section in this is designed to the knitting device (Wirkeinrichtung). The knitting needle is shown diagrammatically in the Figure (Wirknadel) 12 and the guide needle (Legenadel) 13, in order to express the knitting device.

The conveyor belt 7 facing away from the reinforcing section 11 on the end of, the conveying device is provided with a coursee 14, such as the fibrous coursee, it will be in a slicing or web 7 of the upper section of the 8 upper. In 1st case, the conveying device for directly coursee 14 generated in the slice for example, glass fiber fiber slice. In this case, additives conveying device 14 is called "slicer" (Chopperaggregat).

pad gauze 4 horizontally in two conveying device 9, 10 move between, to be more precise, its relative to the conveying direction 6 clip into a certain angle, the angle is formed by a suspension bracket 5 is specified by the angle position. When the pad gauze 4 reaches the conveying device 9, 10, , to the vertical pad gauze in Figure 2 in the plane of sedimentation, in order to make the yarn guided by pad gauze corresponding to the conveying device 9, 10 in. If TIM material, for instance, to the fiber section is now located on the conveyor belt 7 of the upper section of the 8 upper, the using interference states adds the materialpad gauze 4 is carried out, or pad gauze 4 will make coursee, mobile, or otherwise adversely affected.

In order to avoid this kind of interference, can make the conveyor belt 7 of the upper section 8 in the yarn laying device 2, 3 in the area of the settling, in the vertical direction of the shift. On the contrary, the conveying device 9, 10 to maintain the position of the constant. For example, can make the upper section 8 is equal to the decrease in the thickness of the distance coursee, thus pad gauze 4 can freely contact the conveying device 9, 10, on the conveying device 9, 10 is between to guide the yarn is placed on the supporting force of the sufficient coursee.

To this end the conveyor belt 7 in the support Is guided on, instant device with respect to the bracket 2, 3 of the area 15. Sedimentation for moving the double-arrow 16 shown. This settling can be carried out manually, or by not shown in detail for a servo drive mechanism.

Furthermore, bracket is provided with a steering device 17, the steering device can, for example of the metal plate structure bent, the conveying belt 7 along the said steering device sliding guide. Alternatively, the steering roller can also be used. The steering device 17 in its facing reinforcing section 11 is provided with a turning radius of the end of the part, the steering radius portion is relatively small, for example only about 10 mm. In this case, the conveyor belt 7 and the end of the section 11 the gap between the entrance 19 is relatively small, thus the yarn in only a relatively small sector is not conveying belt 7 or reinforced section 11 support.

In another end portion, the support is provided with a driving mechanism 20. The drive mechanism is provided with the motor 22 driving the roller 21. The driving mechanism 20 also in the vertical direction is arranged in fixed position on, this simplifies the structure.

Conveyer belt 7 of the upper section of the 8 a few meters long. Therefore, in the upper section between the device 2, 3 is located in the area of the region, can be 15 the upper. Only in the area of the, can be 15 and the steering device 17 is relatively small between the sector 23 in, the conveyor belt 7 of the upper section 8 of the case is not supported by the guide. However, this is not very important. In the sector 23 in, through coursee supply device 14 is compacted added coursee, that is to say, from below onto the yarn laying device 2, 3 of the yarn sheet produced in the, thus on the reinforced section 11 by two can be generated in the fiber bundle 2, 3 and the flat material coursee. The steering device 17 in the vertical position of the work is kept constant, so that, in the yarn laying device 2, 3 of the two that has been already produced in common and always coursee of the yarn sheet in the same manner into the reinforcing section 11 in. In order to ensure the best operation of the conveyer belt, so that the work input can be adjusted when the vertical position of the steering device.

If the use of two yarn laying device 2, 3, will produce multi-axial fabric. If only use a yarn laying device 2, uniaxial to the fabric to the fabric will be generated. Of course can also be provided with more than two states the pad gauze device 2, 3, in order to produce yarn with other angle direction.

If the material added is not added, can be settled area 15 and towards the yarn laying device 2, 3 the mobile, thus penetrating to the conveying device 9, 10 the yarn can be directly attached to the conveyor belt 7 of the upper section of the 8 upper.

In some cases, for example for maintenance purposes, the conveying of the yarn sheet to gain access to one side of the reinforcing section 11. In this case, the conveying belt 7 together with its bracket must be to move away from the reinforcing section 11. Therefore there is a shift transmission mechanism 24. The shift transmission mechanism 24 so that the conveyer belt 7 together with the bracket (the displaceable region 15, steering device 17 and a driving mechanism 20) along the double-arrow 25 to move away from the reinforcing section in the direction of 11 or towards the reinforcing sector mobile.

In order to prevent the conveyor belt 7 of the upper 8 and may be located on the relative movement between the yarn, so that the shift transmission mechanism 24 and the belt transmission mechanism 20 coupling, this is represented by a dashed line. If shift transmission mechanism 24 the bracket at a predetermined speed to move away from the reinforcing section 11, the belt transmission mechanism 20 so that the upper section 8 in the same speed relative to bracket toward the reinforcing sector 11 mobile, thus the upper section 8 with respect to the lapping device 2, 3 remains stationary.

Not shown in detail can be adopted a way that the roller 21 can be adjusted, that is to say, the roll angle position of the shaft can be changed slightly, in order to make the conveyor belt 7 always accurately along the conveying direction 6 mobile. Can also be in the steering device 17 is provided with a can correct with the mechanism of the conveyer belt.
