Illustrate in greater detail and illustrated other advantages of the present invention by following illustrative embodiment, wherein:
Fig. 1 is the schematic side elevation with coiler device of the arrangement pressure roller that is used for automatic transport lap thin slice.
Fig. 2 is the enlarged diagram of the pressure roller of apparatus of the present invention as shown in Figure 1.
Fig. 3 is the cutaway view along A-A among Fig. 2.
Fig. 4 is the schematic embodiment with pressure roller of plug (dividing plate) opening shown in Figure 2.
The specific embodiment
Fig. 1 represents a kind of coiler device 1, in a similar manner this device has been carried out detailed signal and explanation already among the former disclosed EP-A1-929705.Therefore, in following specification, only the operation principle of this coiler device is done roughly explanation.Adopt shown coiler device 1, produce lap arbor WW by belt R.Belt R is that therefore described belt forms a ring around hard-wired turning cylinder AX between roller R1 and R2 by the roller R1-R6 guiding of fixing or pivotal mounting.In order to produce lap arbor WW by pressure roller K1-K4, lap thin slice W is transported among the ring S, be transported on the circumference of the sleeve H between two roller R1 and the R2.In winding process, sleeve H is sandwiched between two coiling discs that do not illustrate.During lap thin slice WW increased, the strain of ring S phase was big, reaches the expection size up to lap thin slice WW.Can be by directly determine or determine indirectly to have reached the winding diameter of expection in the right sensors of lap arbor periphery by the length that detects the lap thin slice of being carried.In winding process, the motion of belt and/or the control of belt tension finished by tensioning apparatus 3, this device operably moves by a tube Z.By tensioning apparatus 3 a jockey pulley R6 is rotated around axle 4.In winding process, lap arbor WW rotates along direction of rotation D.Before winding process closed to an end, the drive unit of pressure roller K1-K4 cut out.And the drive unit of lap arbor WW is still handled by belt R.Like this, lap separates at the position of prerotation vane metal 6.In case described separation process finishes, coiler device 1 is just shut down.By can roller R2 being rotated around the arm 8 of axle AX rotation, same, roller R3 also can rotate by arm 9.By means of tensioner 3, belt R is further strained, and the lap arbor WW of completion is unloaded on the receiving system, does not illustrate among the figure.After uninstall process, at turn round action roller R2, R3 it is got back on the position shown in Figure 1, and when importing a new sleeve H, just begin once new winding process.What interrelate therewith is to make pressure roller K1-K4 motion once more by a drive unit that does not further illustrate.Equally, by the drive unit that does not illustrate, one of roller R1-R6 of belt R and started by the coiler device of sample, thus form new lap.
As long as to pressure roller K1-K4 supply lap thin slice W, described lap forming process just can be carried out continuously.But, if the supply of lap thin slice is interrupted, for example,, so just the new end of lap thin slice must be imported between the pressure roller K1-K4 if the material supply uses up or during changing material processed, supply discontinuity will take place.Before carrying new lap, the lap arbor WW that still exists should be taken out from ring S, and make coiler device be ready to form new lap arbor.
Finish the supply of new lap thin slice W by guiding sheet metal 11, above the guiding sheet metal, a sensor 13 is installed to pressure roller K1-K4.Guiding sheet metal 11 can also be used as driven conveyer belt, so that with the pressure roller K1 of lap thin slice W automatic transport to the back.For example, lap thin slice W supplies from the stretching device that is installed in the upstream, and the strip with a plurality of supplies in this device is processed into the lap thin slice and/or is processed into lap thin slice W.In EP-A1-679740, disclose a kind of like this embodiment, wherein provide lap arbor to replace described belt, on it, formed described lap.
The hollow space that schematically shows pressure roller K2 and/or K4 in Fig. 1 is connected with vacuum source P by valve 15 and/or 16.Vacuum source P is connected with valve 15,16 by pipeline 17,18.Control by 20,21 couples of vacuum source P of pipeline by control device ST,, valve 15,16 is connected with control device ST by pipeline 34,35 for valve 15,16 is controlled.Valve 15,16 is connected with hole 26 by pipeline 23 and/or 24.Hole 26 (Fig. 3) is positioned at rotating shaft 30 central authorities, and pressure roller K2 and/or K4 are fixedly connected on this rotating shaft.For the sake of clarity, in the enlarged diagram of Fig. 2, only show pressure roller K2, and the claimed device of the present invention.But, as shown in Figure 1, such device can be installed also on pressure roller K4.In the example shown, pressure roller K1 and K3 do not install this device, because be positioned at these two above the roller during the lap thin slice is by these two rollers, therefore, estimate can not go wrong in importing process.But, if wish the end of lap thin slice is more effectively imported, also be not precluded within the possibility that this device is provided on pressure roller K1 and/or the K3.
Shown hole 26 is positioned at pressure roller K2 central authorities substantially, and an exhaust outlet 31 can radially outward be regulated, and leads to the hollow space 33 of the sealing of pressure roller K2 by it.Hollow space 33 is connected by the interior ambient air of opening L and cotton mill, and opening L is arranged on the shell along peripheral U and the width B by pressure roller K2.Opening L can be evenly distributed on the outer surface U, perhaps exists with suitable distribution patterns.Each passage of opening L also can be different.This depends on the position of their relative exhaust outlets 31.It is to be further understood that for hole 26 being extended to the whole length of almost passing rotating shaft 30-so that be distributed on the whole length-several exhaust outlets 31 can also be provided.At last, the quantity of the position of exhaust outlet 31 and size and/or exhaust outlet 31 and the position of opening L and size must be coordinated, so that the restrained force to lap thin slice W is even basically on whole width B.The quantity that is distributed in the opening L on the pressure roller K2 width B also needs to coordinate by this way, so that obtain the enough restrained forces of lap thin slice W.In Fig. 3, rotating shaft 30 is supported in bearing 36 and/or 37, and described bearing connects by the drive unit AT that schematically shows.Can finish described driving by gear or chain drive.In EP-A1-922127, shown a kind of like this drive unit.As shown in the figure, pipeline 23 is connected with rotating shaft 30 by joint 28.Joint 28 can guarantee that pipeline 23 follows rotatablely moving of pressure roller K2 during operation.In order to control importing process and/or produce vacuum on pressure roller K2, control device ST (Fig. 2) is connected with sensor 40 by pipeline 39, and described sensor is installed on the rotating shaft 42 of pressure roller K1, and detects rotatablely moving of this pressure roller by it.By with of known diameter relevant rotatablely move of sensor 40 mensuration, can pass through the transhipment distance that control device ST determines lap thin slice W with pressure roller K1.By sensor 13 and line 14, when the position above the guiding sheet metal 11 that the end of lap thin slice is being used for importing, control device ST just receives a signal.Just be done in such a manner importing process then:
Artificial or automatically the end of lap thin slice W is imported the zone of the sensor 13 that is positioned at guiding sheet metal 11 tops by corresponding transport, in the zone of the clamping line 44 of end between two pressure roller K1 and K2 of lap thin slice.By sensor 13, control device ST receives the signal that lap thin slice end occurs.Now, start vacuum source P and/or valve 15, so that in the hollow space 33 of pressure roller K2, produce vacuum with exhaust outlet 31 by pipeline 17,23 and/or hole 26 by control device ST.Produce an air flow by opening L in this way, as shown by arrows, this air flow is from the surrounding air of pressure roller K2.In case produced vacuum, the drive unit of pressure roller K1-K4 just drops into motion, so that lap thin slice W is transported to the clamping line 45 between next pressure roller K2 and the K3 above the clamping line.In this process, between clamping line 44 and 45, by opening L lap thin slice W is remained on the outer surface U of pressure roller K2 by the vacuum that in hollow space 33, is produced.After the end of lap thin slice passed through between clamping line 45, the end of lap thin slice arrived the case surface of pressure roller K3, and further was transported to the next clamping line 46 between pressure roller K3 and the K4.Subsequently, the lap thin slice end of lap W reaches guiding sheet metal 6, and will enter ring S in its importing coiler device 1 subsequently in this way.Now just can begin the winding process that the front had disclosed already.
After lap thin slice W passes through, in case the end of lap thin slice is positioned at clamping line 45, just cut off vacuum source P by control device ST, and/or shut off valve 15.The distance from clamping line 44 to clamping line 45 that lap thin slice end is passed through is to detect by detecting rotatablely moving of pressure roller K1 with sensor 40, and this sensor transmits signal by line 39 to control device ST.As indicated above then, the end of lap thin slice enters clamping line 46 along the case surface of pressure roller K3, from entering ring S by guiding sheet metal 6 here.So just finish importing process and can begin to form lap.
Operation for fear of the mistake of lap thin slice W, provide a sheet metal 51 in the hollow space 33 that is connected pressure roller K2 according to embodiment illustrated in fig. 4, this sheet metal is distributed on the whole inside diameter freely of pressure roller K2, and the external end at it is provided with diaphragm seal 52, and it forms the sealing contact against the pressure roller that rotates.Sheet metal 51 is fixedlyed connected with a static axle 30a, is provided with hole 26 so that be shown in a 30a as the embodiment of Fig. 3.Diaphragm seal is equipped with in front at sheet metal 51 equally, and the sealing sheet forms sealing with the inside of the flange 48,49 of pressure roller K2 and contacts.Structure for this static axle 30a is used to support the bearing of pressure roller K2 except also need another one the bearing shown in Fig. 3.This means that pressure roller K2 is rotatably installed on the static axle 30a by the bearing arrangement that does not further illustrate.Adopt the device shown in the figure, top hollow space 33a and the hollow space 33 of pressure roller K2 separate, and therefore do not have vacuum at circulation openings L place in the circumferential scope of hollow space 33a.Vacuum only appears at the hollow space 33 towards the circumferential position U of pressure roller K2, and lap thin slice W leads on pressure roller.Can avoid occurring such situation by this device: after the lap thin slice was by clamping line 45, owing to there is vacuum, itself can be looped around described lap thin slice on the pressure roller K2 fully, and undesirable coiling takes place.But, this coiling danger can also be eliminated in the following manner, promptly the lap thin slice terminal by clamping line 45 after soon, just be applied to vacuum in the hollow space of pressure roller K2, as what above disclosed already by control device ST interruption.
Also there are other conceivable embodiments, particularly relate to the separation possibility of the circumferential part of not wishing to be used for lap thin slice guiding.
Adopt the device of being recommended, a kind of device easy to use that can import the safety of new lap thin slice end is provided.Described pressure roller can also with the coiler device conveying that combines so that form lap above the lap arbor at two.Equally, the claimed described pressure roller of the present invention also can be applicable to be designed to process other machineries of lap thin slice.For example, this machinery can be the combing part of combing machinery, is provided for the lap thin slice of combing by it.
