Description

The invention relates to a lifting device for compensating a loading and unloading movement of a supporting mandrel of a bobbin collecting gate, to the associated method for compensating a loading and unloading movement of a supporting mandrel, and to a bobbin distribution device for automatically redistributing a plurality of wound bobbins mounted on a first bobbin collecting gate having a plurality of first supporting mandrels, to a second bobbin collecting gate having a plurality of second supporting mandrels.From the general prior art, devices for loading and unloading coil collecting gates are known.DE2455739A1 discloses an apparatus for bobbin changing in chemical fiber spinning installations. The operating passageway is not occupied by the reel changer and the reel conveyor, but only the absolutely necessary functions are provided in the operating passageway, whereby the part of the function of the reel changing process is moved to other locations.DE10100764A1 discloses an arrangement for exchanging empty spools for full spools. In the arrangement for exchanging empty bobbins for full bobbins, a bobbin collecting gate cooperating with a processing machine is provided which has at least one bobbin collecting gate above a row of gates with lateral run-off positions for subsequent bobbins in the spectrum of which can be displaced suspended in bobbins with a plurality of transport positions for bobbins.DE4211687A1 describes an apparatus for mounting carriages of a carriage gate. The device is suitable in particular for a slant installation with bobbins of different types, wherein the bobbin carriages provided with the mounting device can be moved into a mounting station.The problem in the transfer of coils from a first carrying mandrel to a second carrying mandrel is, in particular, that at the transfer point between a first carrying mandrel and a second carrying mandrel, a displacement of the respective end sections of the respective carrying mandrel can take place, depending on how many coils are mounted on the respective carrying mandrel.This can lead to problems in the displacement of winding spools mounted on the first supporting mandrel towards the second supporting mandrel, since the loading or relief of the respective supporting mandrel can lead to different deflections at the transfer point and can thereby result in a stepwise displacement of the respective end portions, in particular of the loaded supporting mandrels, so that the respective end portions are offset with respect to one another. This can lead to a blockage of the displacement of the winding spools from the first carrying mandrel to the second carrying mandrel.It is therefore an object of the invention to provide a lifting device with which a transfer region free of steps as far as possible can be provided between a first and a second carrying mandrel.It is a further object of the invention to provide a method for compensating a loading and unloading movement of a supporting mandrel.It is also an object to provide an associated bobbin distribution device in which a problem-free transfer of wound bobbins from a first carrying mandrel to a second carrying mandrel is possible.The object is achieved according to the invention with respect to the lifting device with a lifting device having the features according to claim 1.According to one aspect of the invention, a lifting device for compensating a loading and unloading movement of a supporting mandrel of a bobbin collecting gate at a loading and / or an unloading position is provided, wherein the bobbin collecting gate has a freely projecting supporting mandrel, the free projecting end section of which can be deflected in a load-dependent manner, wherein the device is configured for compensating the load-dependent deflection movement of the supporting mandrel by the lifting device being raised and / or lowered via bobbin collecting gates.With the device according to the invention it is possible to align a bobbin collecting gate arranged at a transfer point, such as a loading and / or unloading position, in such a way that a possible deflection movement of the carrying mandrels can be compensated for, so that a transfer of the winding bobbins arranged on the carrying mandrel is possible without any problems.The loading position can be, for example, a position in which the collecting gate is loaded with winding bobbins, such as, for example, the opening of a winder and / or the collecting of winding bobbins from other bobbin collecting gates.The unloading position may be, for example, a position at which a loaded collecting gate is unloaded onto another collecting gate.A winding spool is to be understood in particular as a collecting spool which has a paper sleeve on which a synthetic and / or natural thread is wound.According to a further embodiment of the device, the lifting device for effecting a translatory compensating movement of the supporting mandrel for compensating the deflecting movement in the vertical direction has an eccentric lifting mechanism which is designed for acting on the bobbin collecting gate.The lifting device has an eccentric lifting mechanism which enables a precise and inexpensive change in position of the bobbin collecting gate, so that a possible deflection movement of the supporting pin of the bobbin collecting gate can be compensated precisely at the transfer point.According to another embodiment of the lifting device, the eccentric lifting mechanism has an eccentric disk which can be driven by means of a drive via a shaft and brings about a rotational movement into the translatory compensating movement, wherein the eccentric disk acts on a lifting beam of the eccentric lifting mechanism, which transmits the compensating movement to the bobbin collecting gate.The lifting device has an eccentric lifting mechanism with an eccentric disk which is either set up for different movements by an eccentric arrangement of the shaft or the eccentric disk can have a corresponding elliptical shape, so that with a central arrangement in the center axis of the eccentric disk, a corresponding deflection with higher or lower amounts is possible.In another embodiment, the eccentric lifting mechanism can have a hydraulic and / or pneumatic controlled lifting piston.According to a further embodiment of the lifting device, a translation chassis for forming a translatory compensating movement for compensating a horizontal yielding movement of the supporting mandrel in the horizontal direction is provided on the bobbin collecting gate.A translation chassis is to be understood in particular as a chassis that can provide a translation of the coil collecting gate in the horizontal direction.In particular, a deflection acting in the horizontal direction can be generated with the translation chassis, so that a possible horizontal displacement of the supporting mandrel can be compensated by its deflection by loading or unloading, so that a transition point, which is as step-free as possible, between the supporting mandrel and other positions of the winding reel to be received can be provided. The load is caused by winding coils arranged on the supporting mandrel, which leads to a predetermined deflection of the supporting mandrel. When relieved by removing the winding spools from the supporting mandrel, the supporting mandrel assumes the position which the supporting mandrel has in the unloaded state.According to a further embodiment of the device, the translation chassis has a translation drive which is configured to move back and forth in the horizontal direction of the coil collecting gate.With the translation chassis and the associated translation drive, it is possible in a simple manner to compensate for corresponding horizontal displacements of the collecting gate and the associated supporting mandrels at the respective transfer position.According to an additional embodiment of the lifting device, the lifting beam is coupled to the eccentric disk by a roller for transmitting the rotational movement of the eccentric disk, wherein the roller is movably mounted in a bearing.By means of a roller coupling on the walking beam, a particularly uncomplicated, precise and simple transmission of the compensating movement of the eccentric disk to the walking beam is possible.However, other versions of a lifting device can also be provided, such as, for example, lifting pistons, which have to build up a predetermined oil pressure, so that a precise compensation of the respective deflections is possible.An eccentric disk offers several advantages here, since its compensating movement can be more easily predetermined by the shape or by the degree of eccentric deflection.According to a further embodiment of the device, the lifting device has a guide for the linear guiding of the lifting beam in the vertical direction.In order to ensure accurate and precise control of the lifting movement of the lifting device in the vertical direction, corresponding guides or guide pistons are provided, which prevent the lifting device from being able to yield in non-provided directions.According to an additional embodiment of the lifting device, a compensating support is mounted between the lifting beam and the roller and / or a locating support is mounted on a base plate on which the drive is mounted.The compensation support or the location support have predetermined dimensions. The function of the compensation support or location support is to be able to set the lifting device or the position of the lifting beam exactly, so that a correspondingly suitable eccentric disc can be used and / or that the lifting device can be retrofitted at transfer points.The object is achieved with respect to the method with a method for compensating a loading and unloading movement of a supporting mandrel of a bobbin collecting gate at a loading and / or an unloading position, having the features according to claim 9.According to one aspect of the invention, a method for compensating a loading and unloading movement of a supporting mandrel of a bobbin collecting gate at a loading and / or unloading position is provided, wherein the bobbin collecting gate has a projecting supporting mandrel, the freely projecting end section of which can be deflected as a function of load, wherein the lifting device according to at least one of the preceding embodiments is configured to carry out the method, wherein the deflection behavior of the projecting end section of the supporting mandrel is stored as a function of the load of the supporting mandrel in a database for storing coordinates, wherein the coordinates are retrieved for controlling the lifting device.With the precise detection of the deflection of the supporting pin, for example in tests and storage of the respective deflection for each possible loading and unloading state in a database for storing coordinates, it is possible in a simple manner to control the compensating movement of the lifting device by in each case retrieving the necessary data.According to one embodiment of the method, the coordinates of the database are used at least for controlling a compensating movement of the lifting device in the vertical direction and / or for controlling a compensating movement of the translation chassis in the horizontal direction, such that a substantially step-free transfer region is formed between the first supporting mandrel, on which a winding reel is mounted, and a second supporting mandrel, on which the winding reel is to be displaced, and vice versa.It is also possible to provide a selectively adjustable transfer area with a predetermined gradation (dropping). During the transfer, the receiving support pin should be arranged somewhat lower in order not to damage the sleeves.With the simple and effective evaluation of the corresponding coordinates, the lifting device and / or the translation chassis can be controlled correspondingly precisely, so that a step-free transfer region between adjacent carrying mandrels is possible, onto which transfer of the winding reels is to take place.According to another embodiment of the method, according to which a substantially step-free transfer region is provided between the first carrying mandrel and the second carrying mandrel, a pressing device is activated for transferring a winding reel from the first carrying mandrel to the second carrying mandrel and vice versa.Advantageously, a displacement of a winding spool from a first carrying mandrel to a second carrying mandrel is carried out only when a corresponding step-free transfer has been formed between the first carrying mandrel and the second carrying mandrel.This allows a secure and clean guidance of the winding reel from the first carrying mandrel onto the second carrying mandrel and prevents, for example, damage to the winding reels to be displaced at the transfer region.The object is achieved with respect to the coil distribution device with a coil distribution device having the features according to claim 12.According to one aspect of the invention, a coil distribution device for automatically redistributing a plurality of wound coils, which are mounted on a first coil collecting gate having a plurality of first supporting mandrels, onto a second coil collecting gate having a plurality of supporting mandrels is provided, wherein a transfer region between the first supporting mandrel and the second supporting mandrel is provided with a lifting device according to at least one of the preceding configurations, such that a substantially step-free displacement of the wound coils from the first supporting mandrel onto the second supporting mandrel and vice versa can be carried out.The advantageous use of the lifting device, in particular in the case of bobbin distribution devices, offers a reliable and accident-free transfer of wound bobbins from a first bobbin collecting gate to a second bobbin collecting gate.With the lifting device it is possible to enable a substantially step-free transfer of the winding spools from a first carrying mandrel to a second carrying mandrel, so that a blockage-free and damage-free transfer of the winding spools is possible in each case.Further advantages and exemplary embodiments result from the following description of some exemplary embodiments of the device according to the invention and of the associated method and of the coil distribution device with the lifting device according to the invention.The lifting device according to the invention is explained below with reference to some exemplary embodiments with reference to the attached figures. In conjunction with the lifting device, the method according to the invention and the associated coil distribution device are also described.They represent: FIG. 1 is a schematic top view of a coil distribution device for charging and discharging coil collecting gates; FIG. 2 schematically shows a sectional view according to section guidance A-A from FIG. 1 of a separating device of the coil distribution device; FIG. 3 is a schematic perspective view of a bobbin collecting gate for collecting a plurality of wound bobbins on each supporting mandrel; FIG. 4 is a schematic perspective view of a lifting device for compensating a loading and unloading movement of a supporting mandrel of the bobbin collecting gate shown in FIG. 3; FIG. 5 schematically shows a first side view of the device shown in FIG. 4 ; FIG. 6 schematically shows a second side view of the lifting device shown in FIG. 4 ; and FIG. 7 is a block diagram of the essential method steps for compensating a loading and unloading movement of a supporting mandrel of a bobbin collecting gate.FIG. 1 schematically shows a plan view of a coil distribution device 1 for charging and discharging coil collecting gates 90.In FIG. 3, a coil collecting gate 90 is shown schematically in a perspective view. The bobbin collecting gate 90 has a plurality of carrying collecting mandrels 91 or first carrying mandrels 91, which exert a loading and unloading movement depending on the loading state. The loading and unloading movement is effected by the winding spools 4 (indicated in FIG. 2 ) arranged on the first supporting mandrel 91.When a plurality of wound bobbins 4 arranged in a row one after the other are arranged on the first supporting mandrel 91, the free end section 97 of the first supporting mandrel lowers by a predetermined amount. This deflection movement in the vertical direction is indicated in FIG. 3 with the reference symbol EBB. The horizontal avoidance movement is indicated by HBB in FIG. 3.When the first support mandrel 91 is unloaded, i.e. no winding reel 4 is arranged on the support mandrel 91, the first support mandrel 91 extends substantially along the unloading line E, which corresponds to the centre of gravity line of the first support mandrel 91.When the first carrying mandrel 91 is fully loaded, the first carrying mandrel 91 lowers as far as the load line B.The depression is exaggerated in the figures for better understanding and for better detection.The deflection movement EBB up to the load line B has a vertical deflection movement EBB and a horizontal deflection movement HBB.With the lifting device 70 according to the invention, the vertical deflection movement EBB and the horizontal deflection movement HBB can be compensated accordingly, so that an inexpensive loading and unloading of the respective supporting mandrels 91 is possible.The bobbin collecting frame 90 shown in FIG. 3 is also referred to as a pin container or a drop container, since winding devices are preferably dropped with the bobbin collecting frame, i.e. the wound wound bobbins 4 which are wound into wound bobbins 4 on a non-illustrated winder are dropped onto a first supporting mandrel 91 of the bobbin collecting frame 90 after reaching a predetermined diameter from the respective chuck of the winder. This process is repeated several times until all the first supporting mandrels 91 of the bobbin collecting gate 90 are occupied by winding bobbins 4.The collecting gate 90 shown in FIG. 3 further comprises mandrel carriers 93, to which the first supporting mandrels 91 are fastened. The mandrel beams 93 are secured to support beams 94 which are mounted on a side rail 96.The cross members 92 and the longitudinal members 96 are additionally reinforced with cross members 92.Referring now to FIG. 2, another embodiment of the coil collecting gate 90 is shown. Here, the reinforcement is a perforated sheet metal, while in the exemplary embodiment of FIG. 3 of the coil collecting frame 90, the reinforcement 95 is a diagonal strut 95.The diagonal strut 95 or the reinforcement 95 reinforces the support beam 94 and the longitudinal beam 96 in such a way that the connection point between the support beam 94 and the longitudinal beam 96 is additionally reinforced and can absorb a greater moment without deformation.With further reference to FIG. 1, FIG. 1 schematically shows a plan view of a bobbin distribution apparatus 1, the function of which is to separate or discharge wound bobbins 4 which are fed or discharged via a industrial truck 40, for example in the form of a self-propelled vehicle (automatic guided vehicle) and / or via a fork lift by means of the first bobbin collecting gate 90 at a loading and unloading position or bridge 10 or unloading and loading position or bridge 20, and to a second bobbin collecting gate 100, in particular a suspended transport gate 100.In FIG. 1, the conveying direction FR of the package distribution device 1 is indicated. The conveying direction FR of the suspended transport gates 100 or second bobbin collecting gates 100 takes place via a ceiling rail 2 and a floor rail 3. the floor rail 3 serves for guiding the suspended transport gate 100 on both sides, so that loading and unloading with wound bobbins of the suspended transport gate 100 is possible at the respective transfer regions ÜEB for individualization or for collection, as e.g. at the loading and unloading position 10 or the unloading and loading position 20.The bobbin collecting gates 90 are usually supplied to the bobbin distribution device 1 at the loading position 10 in an automatic collection and unloading device via industrial truck 40. The loaded first package collecting gate 90 is then conveyed via a conveying system 300 from the loading position 10 or loading bridge 10 to a separating device 30 of the package distribution apparatus 1.In the separating device 30, the wound bobbins 4 of the first bobbin collecting gate 90 mounted one after the other in series on the first carrying mandrel 91 are separated onto the second carrying mandrels 104 of a suspended transport gate 100.However, in the bobbin distribution apparatus 1, the reverse process is also possible, so that, for example, wound bobbins 4 held by the suspension transfer gate 100 are collected onto the first bobbin collecting gate 90. Then, a substantially empty first bobbin collecting gate 90 is fed at the unloading position 20 by means of a hall truck 40. Then, at a collecting device 50, the wound bobbins 4 are collected from the suspension transfer gate 100 onto the bobbin collecting gate 90.The full bobbin collecting gate 90 is then fed to the loading position 10 and removed from a hall conveyor 40. The industrial truck 40 may be track-bound and also be a forklift and a lift arm.To control the loading state of the suspended transport gate 10, the reel distribution device 1 has a control device 60 which controls the positions of the second carrying mandrels 104 of the suspended transport gate 100 to a loading or unloading state via sensors, i.e. a winding reel 4 is on the respective carrying mandrel or the carrying mandrel is empty.FIG. 2 schematically illustrates the singulating device 30 of the coil distribution apparatus 1 according to the section guidance A-A from FIG. 1. With the separating device 20, it is possible to separate or transfer wound packages 4, which are collected on the package collecting gate 90 on the respective first carrying mandrel 21 and are mounted, to the suspended transport gate 100 or the second package collecting gate 100.The suspended transport gate 100 has a rail support device 101 which is held such that it can be moved on a ceiling rail 2 and is guided on the opposite side on a floor rail 3, so that an inexpensive separation or transfer of the winding reels 4 to the single carrying mandrel 104 or the second carrying mandrel 104 of the suspended transport gate 100 is possible.The suspended transport gate 100 further comprises a coupling device 102 by means of which the support frame 103 to which the second support mandrels 104 are fastened can be fastened to different support devices 100.For separating the wound bobbins 4 arranged on the first bobbin collecting gate 90 or conveyor collecting gate 90, a pressing device 110 is provided. The pressing device 110 has a corresponding number of pressing punches 111, wherein the number of pressing punches 111 substantially corresponds to the number of carrying mandrels 91 of the conveying collecting gate 90.The pressing rams 111 are offset in the vertical direction V with respect to the supporting mandrel 91 in such a way that the end section of the respective pressing ram 111 can engage below the first supporting mandrel 91, so that the respective winding reel 4 is displaced by displacing the pressing ram 111 in the translation movement 115 substantially parallel to the direction of extent of the first supporting mandrel 91, transferring or conveying the winding reel 4 towards the second supporting mandrel 104 of the suspended transport gate 100 is displaced.The pressing punches 111 are fastened to a punch support 112 and are movable back and forth in the direction of translation movement 115 via a longitudinal displacement device 114 substantially parallel to the direction of extension and length of extension of the respective supporting mandrels 91, so that the winding bobbins 4 mounted on the respective supporting mandrel 91 can be displaced over the entire length of the first supporting mandrel 91 and onto the associated second supporting mandrel 104 of the suspended transport gate 100.As can also be seen from FIG. 2, a first package collecting gate 90 is positioned in the separating device 30 for separating the wound packages 4 onto the suspended transport gate 100.Due to the complete loading with winding spools 4 of the first spool collecting gate 90 or the associated first carrying mandrels 91, the carrying mandrel 91 can be lowered in accordance with the loading line B. However, in order that the winding bobbins 4 can be transferred without problems by means of the pressing device 100, the carrying mandrels 91, in particular their end sections 97, must be brought at the level of the transport line T. In order to compensate for the deflection movement EBBin the vertical direction V (see also FIG. 3 ), the lifting device 70 according to the invention is provided at a predetermined location adjacent to the transfer region ÜEBon the underside of the bobbin collecting gate 90. The function of the lifting device 70 is to lift the bobbin collecting gate 90 so that at least the end portions 97 of the first carrying mandrels 91 are brought into the position of the transport line T.As the discharge proceeds or as the respective wound coils 4 are discharged, the load line B also changes and the supporting mandrel 91 approaches the transport line T again, the load line coming closer to the load line E depending on the degree of load. To compensate for the horizontal yielding movement of the supporting pin, it is also possible to move the bobbin collecting gate 90 by means of a translation chassis 85 with a translation drive 86 horizontally closer to the suspended transport gate 10 in order to be able to compensate for a corresponding horizontal yielding movement HBB in the horizontal direction H, so that the supporting pins are arranged together at least at the associated end sections of the bobbin collecting gate 90 and the suspended transport gate 10 at the level of the transport line T.The load line B is exaggerated for better sensing. Furthermore, the first supporting mandrel 91 is not fully occupied by winding spools 4 for the same reason.On a supporting frame 200, there are disposed the ceiling rail 2, the floor rail 3 and a collecting device 50 for collecting the wound bobbins of the suspended transporting gate 100 on the bobbin collecting gate 90. The position of the collecting device 50 is shown in more detail in FIG. 1. In the collecting device 50, exactly the reverse operation takes place, namely the transfer of winding bobbins 4 from the suspension transport gate 100 to the bobbin collecting gate.In the collecting device 50, the winding bobbins 4 of the suspension transfer gate 100 are transferred to the bobbin collecting gate 90 by the collecting device 50. This in turn leads to a corresponding lowering of the first supporting mandrels 91 with increasing load or with increasing number of winding spools 4 arranged thereon.In FIGS. 4 to 6, different views of the lifting device 70 according to the invention are shown.FIG. 4 shows a perspective view of the lifting device 70.The lifting device 70 is configured in particular for compensating the vertical deflection movement in the vertical direction V (see FIG. 2 ), such that the vertical deflection movement EBBof the individual supporting mandrels 91 can be compensated according to the respective degree of loading.In order to determine the associated deflections and deflection coordinates of the carrying mandrels 91 exactly, the respective deflections of the carrying mandrels 91 are recorded beforehand in tests as a function of the respective load, i.e. given a corresponding number of winding reels 4.These deflections can then be evaluated in a program or stored in a database, so that the lifting device 70 according to the invention can be programmed or regulated in such a way that the corresponding necessary compensating movement in the V direction of the lifting device 70 can take place at the coil collecting gate 90.For carrying out the vertical compensating movement V, the lifting device 70 has an eccentric lifting mechanism 80. The eccentric lifting mechanism 80 has an eccentric disk 72, which has a circular circumference in the exemplary embodiment shown in FIGS. 4-6. In order that a corresponding height adjustment is possible by means of the eccentric disk 72, the eccentric disk 72 is eccentrically coupled to a drive 73 by means of a shaft 77.By operating the drive 73, the shaft 77 is rotated and the eccentric disc is moved accordingly. Due to the eccentric arrangement of the shaft in the eccentric disk 72, a corresponding stroke can be caused. For transmitting the lifting movement of the eccentric disc 72, the latter is connected to a lifting beam 75 via rollers 78. The rollers 78 are rotatably supported in a bearing 79. For compensating different height differences, location supports 8 and compensation supports 76 are provided at suitable positions in the lifting device 70. It is thus possible to retrofit the lifting device 70 also on existing coil distribution devices 1.For separating or collecting the winding coils 4, a block diagram is shown in FIG. 7 which describes the individual method steps for separating or collecting winding coils 4 with the aid of the lifting device 70.In a first method step S 1, a first bobbin collecting gate 90 is fed at a loading position 10 with a first carrying mandrel 91 loaded with wound bobbins, which have a corresponding deflection, to the separating apparatus 1 via a floor conveyor vehicle 10.By means of the conveying system 300, the loaded first bobbin collecting gates 90 are then fed to the separating device 30. When the bobbin collecting gate 90 is arranged at the transfer region ÜEB by means of the conveying system 300, the deflections of the carrying mandrel 91 are retrieved in a coordinate database in a first method step, so that the lifting device exerts the translatory compensating movement V.Here, the drive 73 is driven accordingly, so that the eccentric disk 72 moves the lifting beam by the predetermined compensating movement V.Furthermore, in a further step S 2, a compensating movement takes place in the horizontal direction H by means of the translation chassis 85, such that the bobbin collecting gate 90 adjoins the predetermined transport line T, or the respective end sections of the first carrying mandrels 91 and of the second carrying mandrels 104, such that a transfer of the winding bobbin 4 from the first carrying mandrel 91 to the second carrying mandrel 104 can take place at the transfer region without any effort and without steps. In this case, the necessary data are also called up from the coordinate database.In a third step S 3, after a step-free transfer region UEB between the first carrying mandrel 91 and the second carrying mandrel 104 has been provided by the lifting device 70 and by the translation chassis 85, the pressing device 110 is activated, so that at least one winding reel 4 can be displaced from the first carrying mandrel 91 onto the second carrying mandrel 104.In a further step S4, the further transport of the loaded suspension transport gate 100 then takes place, wherein the above-described process for the bobbin collecting gate 90 is continued until the respective supporting mandrel 91 is completely unloaded and the winding bobbins 4 have been transferred to the suspension transport gate.The process with the separation can also be carried out differently for collection at the collection device 50.List of reference characters1 Bobbin distribution device 2 Ceiling rail 3 Floor rail 4 Winding bobbin 7 Support 8 Location support 10 Loading / unloading position / bridge 20 Unloading / loading position / bridge 30 Separating device 40 Industrial truck 50 Collecting device 60 Control device 70 Lifting device 71 Base plate 72 Eccentric disk 73 Drive 74 Lifting guide 75 Lifting beam 76 Compensating support 77 Shaft 78 Roller 79 Bearing 80 Eccentric lifting mechanism 85 Translation running mechanism 86 Translation drive 90 First bobbin collecting gate; Conveyor collecting gate 91 Carrying collecting mandrel, first carrying mandrel 92 Cross member 93 Mandrel carrier 94 Supporting carrier 95 Reinforcement 96 Longitudinal member 97 Mandrel end portion 100 Suspended transporting gate; second bobbin collecting gate 101 rail supporting device 102 coupling device 103 supporting frame 104 supporting single mandrel, second supporting mandrel 105 bottom guide 110 pressing device 111 pressing plunger 112 plunger support 114 longitudinal displacement device 115 translation movement 200 supporting frame 300 conveying installation E relief line B load line EBB loading and relief movement, vertical deflection movement HBB horizontal deflection movement T transport line UEB transfer regionReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
