Description

Transport device on the spinning machine

technical field

The invention relates to a transport device for empty or wound tubes of a spinning machine, in particular a ring spinning machine, wherein at least one endless conveyor is located in one or more groups of spinning stations of the spinning machine Extend around and connect to the drive unit.

Background technique

This transport device is known from EP 450 661 A1, with which the tubes (packages, cops) wound at the individual spinning stations are transported away and transferred to the subsequent winder and another collection point . The tube is placed onto a tube spindle mounted on a peg pallet. The peg pallets are displaced on slide rails and fed to a collection point by means of carriers mounted on endless conveyors (eg ropes or steel belts). This collection point or winder is usually located at the head end or the foot end of the spinning machine. Transfer to subsequent winders or collection points is handled by properly designed outputs. Such a device is shown, for example, in DE 4129 537 C2. In order to produce new packages again, the empty tubes are again placed on the now emptied tube spindles of the peg pallet and transferred to the corresponding spinning station by means of a transport device. In order to achieve a precise positioning of the empty tubes at the respective spinning station, at least one sensor is arranged in the vicinity of the transport device (eg on the endless conveyor), which at least one sensor can identify the respective position of the peg tray relative to the spinning station.

In practice, it has been found that, due to the increased length of the spinning machine, driving problems for driving the endless conveyor can arise. This problem can occur due to slippage between the drive wheels and the endless conveyor (traction member). In order to counteract this slippage, it is proposed in DE 197 55 973 A1 to provide at least two drives for driving the endless conveyor and to provide the drives at respective mutually distal ends of the endless conveyor.

If the number of spindles is increased further (eg beyond 2000 spindles), in some cases this measure may no longer be sufficient to completely remedy the associated slippage problem. In conventional spinning machines, the spinning stations are arranged next to each other on their two longitudinal sides. This means that in a spinning machine with 2000 spinning stations, 1000 spinning stations are arranged on each longitudinal side. Ring conveyors for transporting tubes and packages (cops) run along both longitudinal sides of the spinning machine.

In order to optimally utilize the existing required space in spinning mills, there is a need for spinning machines (eg ring spinning machines) with a large number of spindles. By further increasing the length of the spinning machine and thus also the length of the endless conveyor, not only the above-mentioned problems with regard to slippage may become more pronounced, but also problems involving an increased elongation of the endless conveyor occur, which in some cases Inaccurate positioning of the peg trays with tubes at the respective spinning stations may result. The tension adjustment devices previously used on endless conveyors also hit their limits in their effectiveness.

Contents of the invention

It is therefore the object of the present invention to propose a transport device for transporting winding tubes (packages, cops) and empty tubes on a spinning machine which eliminates the known disadvantages and is especially suitable for use with a large number of spindles Spinning machine used together.

This object is achieved by proposing—when viewed in the longitudinal direction of the spinning machine—that the transport device has at least two subsections arranged in succession, each subsection having an endless conveyor, and transferring Devices are provided between the sub-sections for transferring empty or full yarn carriers between directly opposite ends of the sub-sections.

By dividing the transport device into at least two subsections, the length of the respective endless conveyor can be substantially reduced and problems relating to slippage during the drive transmission and the longer longitudinal extension of the endless conveyor no longer occur. The load on the tensioning device of the endless conveyor for the respective subsection is also reduced.

Furthermore, it is proposed that the respective endless conveyors are provided with carriages and routed around deflecting rollers, wherein at least one deflecting roller of each endless conveyor is connected to a drive member and the carriages transport peg pallets guided on skids, which The peg tray carries an empty yarn carrier or a wound yarn carrier and is transferred between directly opposite ends of the longitudinal sides of the sub-sections by a transfer device.

Tubes or wound tubes (cops, packages) supported on peg pallets can thus be transferred from one subsection to another in a simple manner in the vicinity of the transfer device, especially due to the Retained on the tube or on the transport member of the package. That is, the transport unit (peg pallet) loaded with tubes or packages is disengaged from the carrier of one subsection near the transfer unit and fed by the transfer unit to the carrier of the other subsection of the transport unit. shelf.

In order to ensure a slip-free drive even in the case of a longer length of the subsections of the transport device, it is proposed that at least two deflection rollers of each subsection are connected to the corresponding drive member, wherein the first drive member of each subsection are respectively arranged near mutually opposite ends of the sub-sections, and wherein the second drive member is respectively arranged near the ends of the sub-sections which are furthest apart from each other.

In order to guide the peg pallet with installed tubes or packages in a controlled and reliable manner during the transfer at the transfer device, it is proposed that the transfer device has at least two for the peg pallet extending in the longitudinal direction of the spinning machine. There are two guides spaced apart from each other, and each guide is provided with an inlet area and an outlet area. These guides are basically lateral guides and horizontal guides for the peg trays near the transfer unit.

In order to transfer the peg pallets to the carriages of the endless conveyor of another subsection within a defined time frame, it is proposed that the guide for conveying the peg pallets has a transport member connected to and driven by a drive device . This ensures that no gaps can occur on the carriers of the endless conveyor.

The transport member can preferably be an endless belt, the outer contour of which protrudes partially into the transport area of the peg tray in the respective guide. Thus, the peg tray guided in the corresponding guide is entrained by frictional engagement with the driven belt. It is also possible to provide a form-fitting entrainment strip, in which case the strip can be provided with raised areas which can engage with grooves provided in the peg tray.

Furthermore, it is proposed that the guide is provided with a lower sliding surface provided with a free channel extending in the longitudinal direction of the guide and into which the strip protrudes.

A frictional engagement is thus created between the belt (eg round belt) and the lower sliding surface of the peg tray, which ensures reliable entrainment, especially since the peg tray rests on the belt with its full weight.

In order to ensure a reliable supply of the peg trays to and removal of the peg trays from the guide of the transfer device, it is also proposed to guide the belt on a disc mounted rotatable about a vertically oriented axis of rotation , wherein a disc is arranged in the inlet region and the outlet region of the respective guides and the other disc is arranged between the guides. The additional disc can also be arranged between the inlet area and the outlet area of the guide and be connected to drive means by means of which the belt is driven.

By virtue of this arrangement of the pucks and the belt guided on the pucks, a reliable capture of the peg trays during pickup and delivery at the transfer device is ensured.

In order to reliably separate the peg pallets from the corresponding carriages of the endless conveyor at the point of transfer to the guides of the transfer device and to reliably couple the peg pallets to the corresponding carriages of the endless conveyor, it is also proposed Guide elements are arranged in the respective inlet and outlet regions of the guide on sliding surfaces extending transversely to the guide, wherein the slide surfaces are flush with the slide surfaces of the corresponding subsections of the transport device, and wherein the guide elements protrude into In the transport path of the peg tray held on the carrier, and in the corresponding inlet area of the guide, the peg tray is deflected to the guide and the peg tray is fed to the corresponding part of the transport device in the corresponding outlet area of the guide. Carrier for subsections.

When the peg pallet hits the guide surface of the guide member in the respective inlet region of the guide, the peg pallet is separated from the carrier of the transport device and fed to the respective guide. In the exit region of the respective guide, a guide member provided with a corresponding guide surface enables the feeding of the peg tray delivered from the guide to the waiting carriage of the transport device.

Preferably, the guide member can be installed in a detachable manner. This ensures independent transport of the peg pallets within the subsections of the transport device. That is to say, once in the vicinity of the transfer device, the peg pallets transported on the sub-sections of the transport device are no longer separated from the carriers by guide elements and fed past the transfer device on a so-called bypass, but Do not transfer to the next subsection. This can be advantageous, for example, if the area of the spinning machine associated with the next subsection of the transport device has to be shut down due to a fault. That is to say, the first section of the spinning machine can continue to operate autonomously.

In order to also monitor the area within the respective guide of the transfer device, it is proposed that at least one sensor be arranged between the entry area and the exit area of each guide of the transfer device in order to detect the tube or reel. It is also conceivable to directly detect the presence of the peg tray in the guide by a sensor.

In order to control the transport of the respective sub-sections of the transport device with the transport in the transfer device, it is proposed that at least one sensor for detecting the position of the peg pallet held by the carrier of the endless conveyor is connected with the transport device in the vicinity of the transfer device Associated with each subsection. Like the sensors of the guides of the transfer device, these sensors are connected to a control unit, by means of which the corresponding drives of the subsections of the transport device and the drives of the transport members in the transfer device are coordinated with each other in order to ensure the movement of the peg pallets. Uninterrupted and trouble-free transfer.

It is also proposed that—when viewed in the longitudinal direction of the spinning machine—the transfer device is displaceably attached to the spinning machine, in which case the The deflection rollers of the endless conveyor are rotatably mounted on the transfer device. Thus, it is possible to displace the deflection rollers supported on the transfer device by displacing the transfer device.

One of the endless conveyors of the subsections of the transport device can be tensioned in this way. For the other endless conveyors of the other sub-section, a separate tensioning device is provided, mounted at the end of the endless conveyor, pointing away from the transfer device.

Furthermore, a spinning machine is proposed, in particular a ring spinning machine with a transport device embodied according to the invention.

It is thus proposed to provide a free passage above the transfer device, which divides the spinning machine into two subareas, wherein each subarea is provided with its own drive element.

The free passage provided enables the operator to quickly access the opposite side of the spinning machine in order to carry out the necessary operations. In particular, this is advantageous if a spinning machine with a large number of spindles has to be operated for a long time. Thus, the distances involved in the two-sided operation of the spinning machine can be substantially reduced. Furthermore, due to the division of the spinning machine into subareas with its own drive elements, a better and optimized drive concept can be achieved with regard to spinning machines equipped with a larger number of spindles.

In order to facilitate the transfer of the operator in the area of free passage, it is proposed to provide a walkable cover above the transfer device.

In order to synchronize the drives, control systems of the drive elements of the subregions of the spinning machine and of the drives of the transfer device are additionally provided, as well as sensors of the transfer device and pins for detecting the corresponding subsections of the transport device A sensor for the position of the column tray is connected to the central control unit.

Detailed ways

Figure 1 shows a schematic top view of a known spinning machine, for example a ring spinning machine 1, provided on its front side A and on its rear side B with a plurality of Spinning Station 2. For example, the spinning station is provided with a drafting mechanism (not shown) which is fed with roving from a package arranged above the drafting mechanism. The yarn formed at the corresponding drafting unit is wound via a ring/traveler combination onto a rotating empty tube H to form a package S (also called cop). During the winding process, the tube sits on the driven spindle of the spindle rail. After the tube has been completely wound, the formed package S is delivered to a transport device T by means of known means (not shown - eg a doffer beam or a movable doffer). The transport device has an endless endless conveyor 4 routed around deflecting rollers R1 to R4 which are rotatably mounted on the frame MG. The two deflection rollers R1, R4 are in driving engagement with respective drive motors M1, M2. The endless conveyor 4 (which may consist, for example, of a steel belt) has grippers 5 spaced along its entire length, only a few of which are shown schematically. In order to maintain the endless conveyor under tension, a tension adjustment device 6 (schematically shown) is provided, by means of which the axis of rotation of the deflecting rollers R1, R2 is pushed away from the axis of rotation of the deflecting rollers R3, R4 . Although not visible, the deflection rollers R1 , R2 are mounted such that they can be displaced on the machine frame MG and are fixed on the machine frame MG.

The finished packages S removed from the spindles are placed onto pegs 8 of peg pallets ("trays" for short) which run around the spinning machine 1 in the horizontal plane on slide rails 11 in the conveying direction FR. guide. A (for example disc-shaped) tray 9 is held by the gripper 5 , wherein the tray is entrained during the longitudinal displacement of the endless conveyor 4 and transported along the spinning machine 1 .

In FIG. 1 , the top part K of the spinning machine 1 is indicated schematically, in which top part K the drive of the spinning machine 1 is housed. A winding machine SM is arranged next to the opposite bottom part F, to which the packages S are delivered for further processing, eg via suitable delivery means. Such a delivery device is disclosed, for example, in DE 41 29 537 C2. As also indicated schematically by arrows, the tube H emptied at the winding machine SM is fed back to the transport device T by means of a transfer device (not shown in further detail). That is to say, the empty tubes H are placed here again on the pegs of the pallet 9 and are fed to the spinning station 2 in the conveying direction FR. In order to ensure precise positioning of the trays at the individual spinning stations at least one sensor SE is provided which detects the position of the gripper 5 of the endless conveyor 4 .

The sensor SE transmits its signal to the control unit ST, by means of which signal the motors M1 and M2 are appropriately controlled. Instead of the winding machine SM, it is also possible to provide only a collection device for the packages, from which the packages are then transferred manually or by means of a suitable transport device to the subsequent winding machine.

Fig. 2 also shows a top view of the spinning machine 1 according to Fig. 1, but in contrast to the example of Fig. 1, showing the division of the transport device T proposed according to the invention with its endless conveyors 4a, 4b into Two successively arranged subsections T1 , T2 . Between the mutually opposite ends E1 , E2 of the subsections T1 , T2 is installed a transfer device 14 , by means of which transfer device 14 the trays 9 loaded with empty or full tubes are delivered or transferred between the subsections T1 , T2 . An enlarged detail of the transfer device 14 can be seen in FIG. 4 .

The endless conveyor 4a of the first subsection T1 is guided on deflecting rollers R3, R4, R7 and R8, wherein the deflecting rollers R4 and R7 are in driving engagement with motors M1 and M2, respectively. The adjoining second subsection T2 of the transport device T is equipped with a second endless conveyor 4b, which is routed around deflecting rollers R1, R2, R5 and R6, wherein the deflecting rollers R2 and R5 are respectively connected to Motor M3 or M4 performs driving engagement.

Also in this example, a front side A is provided at the end of the subsection T1 of the conveying device, in which front side A the drive of the spinning machine is accommodated. In another exemplary embodiment according to FIG. 3 a further drive scheme is shown, in which the spinning machine is driven from both ends of the spinning machine, which will be described in further detail below. describe. As already described in the example according to FIG. 1 , in the example according to FIG. 2 also a winding machine SM is arranged next to the opposite end of the front side A of the bottom part F. As shown in FIG. Supports or additional drive elements for driven longitudinal members such as drafting rollers can be housed in the bottom part F.

The transfer device 14 (which is also shown in FIG. 5 in the enlarged side view X according to FIG. 4) is provided with two guides 16, 17 which are at a distance from 1, each guide has an inlet area and an outlet area ET, AT. The pallets 9 carrying the tubes H or the packages S are routed within the transfer device 14 on these guides 16 , 17 . After the entry area or exit area ET, AT, the transfer device 14 has a corresponding sliding surface GF which extends in the same vertical plane as the sliding surface of the slide rail 11 also extends. In this way, it is ensured that the pallet 9 can be transferred without any hindrance or difficulty from the slide rail 11 to the corresponding sliding surface GF of the transfer device 14 and vice versa.

After the respective inlet and outlet regions ET and AT of the guides 16, 17, guide members F1-F4 are arranged above the sliding surface GF, which protrude into the conveying path of the pallet 9 and strike The guide member deflects the tray 9 properly.

For example, if the driven, first endless conveyor 4a takes the tray carrying the completed package S from the first section of the rear longitudinal side of the spinning machine 1 via the gripper 5 attached to the endless conveyor The sliding surface of the slide rail 11 is transferred to the sliding surface GF of the transfer device 14, then the tray 9 strikes with its outer edge against the inclined guide surface FF of the guide member F1 and is thus deflected towards the entry area ET of the guide 16. During this deflection process, the pallet is released from the gripper 5 and travels to the sliding surface 3 of the guide 16 . The guide surface of the slide rail 11, the slide surface GF, and the slide surface 3 of the guide 16 are located on a common horizontal plane.

To support this release, and to transport the pallet within the guide 16, a driven belt 20 is provided which is routed around the discs S1 to S5. The belt is driven from a disc S5 which is rotatably mounted between the guides 16, 17 and partly surrounded by the belt. Disc S5 is in driving engagement with motor M5.

The belt is guided in such a way that it protrudes through a slot Z provided along the sliding surface 3 to an area above the sliding surface 3 (see FIG. 5 ). The opening of the groove Z protrudes partially into the region of the sliding surface GF. Due to this arrangement, the belt 20 comes into frictional contact with the underside U of the respective tray 9 , which is thus displaced along the guide 16 to the outlet area AT. By this displacement, the tray 9 strikes the guide surface FF of the guide member F2 and deflects along this guide surface transverse to the longitudinal direction of the guide 16 . During this deflection process, in which the pallet is guided on the sliding surface GF, the pallet is pushed upwards onto the available gripper 5 of the second endless conveyor 4b of the second subsection T2 of the transport device T. Via the driven endless conveyor 4b, the pallets 9 are continuously transferred from the first subsection T1 to the subsection T2 by means of the transfer device 14 in the manner described in the conveying direction FR of the subsequent winding machine SM. In order to avoid collisions between the pallets 9 in the vicinity of the transfer device 14, sensors 22 and 23 are respectively arranged in the area of the corresponding guides 16 and 17, which sensors 22 and 23 recognize that the guides 16 and 17 are loaded with packages S or The presence or absence of a tray for tube H. Furthermore, a sensor 25 is arranged in front of the entry area ET of the guide 16 and a sensor 26 is arranged in front of the entry area ET of the guide 17 , which sensors 25 and 26 monitor the presence of the pallet to be transferred. These sensors 22, 23, 25, 26 are connected to a control unit ST which controls the motors M1 to M5. In this way, the drive of the two subsections T1 , T2 can be coordinated, thus ensuring uninterrupted transport of the pallets while preventing collisions in the vicinity of the transfer device 14 .

As can be seen from the illustration in Figure 2, the pallet 9 loaded with packages in the second section A2 of the front longitudinal side of the spinning machine 1 has been transferred to the first section of the front longitudinal side of the spinning machine segment A1.

In the second section A2 of the spinning machine, pallets 9 loaded with empty tubes H have been transported in the transport direction FR from the second subsection T2 of the transport device to the individual spinning stations 2 . The pipe G has been delivered from the winder to an empty tray 9 passing through the transfer point of the winder SM (schematically indicated by the arrow) via the endless conveyor 4b.

The transfer of the pallet 9 loaded with tubes H from the second section A2 of the spinning machine 1 to the first section A1 by means of the transfer device 14 is carried out in accordance with what was previously described between the rear longitudinal sections B1 and B2 of the spinning machine. The transfer of the tray 9 loaded with the package S is performed in the same manner as between the two.

The tray loaded with the pipes H is displaced via the driven endless conveyor 4b to the vicinity of the guide member F3 on the sliding surface GF and hits the guide surface FF of the guide member F3. The presence of the tray 9 is detected by the sensor 26 and the presence of the tray 9 is reported to the control unit ST.

Even before the displacement of the tray 9 on the guide surface FF towards the entry area ET of the guide 17 , the sensor 23 checks whether space within the guide is available for advancing an additional tray 9 . If this has been reported to the control unit ST, the transfer step is enabled. Under the influence of the belt 20 protruding partially into the area of the sliding surface 7 through the slot Z, the tray 9 is transferred on this sliding surface 7 to the exit area AT of the guide 17 and then hits the guide surface FF of the guide member F4. On this guide surface FF and under the influence of the belt 20, the pallet is transferred to the already available gripper 5 of the first endless conveyor 4a. The tray 9 is transferred from the sliding surface 7 to the sliding surface GF, which is flush with the sliding surface 7 .

The transport of pallets loaded with empty tubes H continues until empty tubes to be transferred to the spindles are available at all spinning stations 2 of the spinning machine 1 .

In order to maintain the endless conveyor 4b under tension, a tension adjustment device 6 (schematically shown) is provided, by means of which the axis of rotation of the deflection rollers R1, R2 is pushed away from the rotation of the deflection rollers R5, R6 shaft, the deflection rollers R5, R6 are rotatably mounted on a frame 30 displaceably attached to the frame MG. The vertically aligned axes of the deflection rollers R7 and R8 of the first subsection T1 of the transport device T are also supported on this frame 30 which supports the transfer device 14 . As indicated by the double arrow in Fig. 2, the frame 30 is displaceably attached to the machine frame in order to tension the first endless conveyor 4a. The deflection rollers R3, R4 are fixedly and rotatably mounted in the frame MG. A detailed illustration of the displaceable frame 30 can be seen in FIG. 4 . In order to tension the endless conveyor 4a, the frame 30 with loose screws P is moved by means of an actuator 31 (schematically shown) towards the deflection roller R1 relative to the machine frame MG along the provided slotted hole L , R2 shift. Screws P are then tightened, thereby securing the frame in place on frame MG. The tension adjustment of the endless conveyor 4b is done by means of a tension adjustment device 6 provided with spring elements.

As already described in the exemplary embodiment of FIG. 1 , the sensors SE are used to position the trays 9 for delivering the tubes H to the individual spinning stations 2 .

The motors M1 to M5 are connected via lines m1 to m5 to and controlled by a control unit ST. In order to synchronize the drive of the first sub-section T1 of the transport device with the drive of the second sub-section T2 , the drive motors M1 , M2 are operated as “primary” with respect to the drive motors M3 , M4 .

Fig. 3 shows a schematic side view of the exemplary embodiment according to Fig. 2, wherein the spinning machine 1 has been subdivided into two sub-areas 38, 39 so that there is a free passage DR with space for the operator. Steps (not shown) may be provided to make it easier for an operator to climb up and across transfer device 14 . This facilitates the operation of the spinning machine, especially if the spinning machine extends over large distances due to the large number of spindles. That is, if a fault occurs at the spinning station on the rear side of the spinning machine, a shortcut in the form of a free passage DR is available for the operator to reach the rear side of the spinning machine and remedy the problem. This increases the capacity utilization of the spinning machine since downtimes at the spinning station can be reduced. Furthermore, the additional free channel DR has advantages in terms of safety. With the provided free passage, escape routes in spinning mills can be shortened in some cases.

As can also be seen in the exemplary embodiment of FIG. 3 , the transport device is arranged above the spinning machine in the form of overhead rails 33 on which the roving packages 35 are fed to the individual spinning stations 2 . The installation of the overhead rail 33 in the vertical direction is chosen such that there is no collision with an operator passing through the spinning machine 1 in the vicinity of the free passage DR.

For the first sub-area 38 of the spinning machine 1, in addition to the top part K with the drive motor MA for driving the spinning station 2 (draft mechanism, spindle, etc.), an intermediate part Z1 is provided, a second longitudinal part The frame of a subregion 38 is supported on the intermediate part Z1 and the longitudinal axis 41 of the drafting mechanism is supported on the intermediate part Z1.

For the second subarea 39 of the spinning machine 1, in addition to the bottom part F with the drive motor MB for driving the spinning station 2 (draft mechanism, spindles, etc.), an intermediate part Z2 is provided, the first longitudinal part The frame of a subregion 39 is supported on the intermediate part Z2 and the longitudinal axis 42 of the drafting mechanism is supported on the intermediate part Z2.

Additional drives for the longitudinal axes 41 , 42 can also be provided in the intermediate parts Z1 , Z2 . Arranged after the bottom part F of the second sub-area 39 is a winding machine SM to which the packages delivered from the endless conveyor 4b are fed by means (not shown). By means of means also not shown, the empty pipes H are delivered again from the winding machine SM to the peg trays 9 held by the endless conveyor 4b.

The transfer of the package S or tube H at the transfer device is done as already described in the exemplary embodiment of FIG. 4 .

In order to ensure synchronous operation of the drives of the spinning machine 1, the control systems C1 and C2 of the drive motors MA, MB are connected to the central control unit ST. Motor MA operates as a "master (motor)" and motor MB operates as a "slave (motor)" in relation to motor MA. Likewise, the control system C3 for controlling the motors M1, M2 for driving the first endless conveyor 4a and the control system C4 for controlling the motors M4, M4 for driving the second endless conveyor 4b, and The control system C5 for controlling the motor M5 for driving the conveyor inside the transfer device 14 is connected to the central control unit ST. As already described above, the control systems of the motors M1 to M5 are coordinated with each other via this control unit ST, so as to ensure a fail-free transfer of packages S or tubes H in the vicinity of the transfer device 14 . For this purpose, the aforementioned sensors SE, 25 and 26 ( FIGS. 2 , 4 ) are also integrated. The input line se of the sensor SE into the control unit ST is shown schematically here. Other input lines of the schematically shown control unit ST represent additional connections to other sensors (not shown), such as, for example, sensors 22 , 23 and 25 , 26 .

If the first subsection 38 of the spinning machine 1 has to be shut down due to a fault, the second subsection 39 can be continuously operated autonomously via the control unit ST in order to avoid production losses due to a shutdown of the first subsection 38 . Only the motors MB, M3 and M4 are then put into operation via the control unit ST. Furthermore, the guide members F2 and F3 of the transfer device 14 are removed so that the peg trays 9 held on the grippers 5 of the endless conveyor 4b are no longer deflected towards the guide 17 and can also pass freely through the guide 16 exit area AT.

Additional exemplary embodiments are also possible within the scope of the present invention.
