Description

Technical Field

[0001] The present invention relates to a take-up winding machine as set forth in the preamble of claim 1 for winding a plurality of yarns to form a package.

[0002] In the production of synthetic yarns in a melt spinning process, the yarns produced as a group at the spinning position are wound side by side and parallel to form a package. For this purpose, a special take-up winding machine with a large protruding winding spindle is used to receive a plurality of packages wound side by side and parallel. Thereby, on one winding spindle, 10, 12 or even 16 packages can be wound simultaneously. In order to be able to wind the continuously produced yarn in melt spinning without any substantial interruption to form a package, the take-up winding machine is provided with two winding spindles that are offset from each other by 180° parallel to each other and held by a rotatable winding turret. The winding spindles are alternately guided by the winding turret to an operating area for winding the package and an exchange area for removing the fully wound package. Here, the winding spindles in the operating area are assigned a plurality of winding positions for winding one yarn at each winding position to form one package. This type of take-up winding machine is known, for example, from German Patent Application Publication No. 102016009994.

[0003] In a known take-up winding machine, the operation of the drive device and the actuator is performed by an operating device arranged at the end side of the machine frame. The operating device has a plurality of control keys, whereby individual functions, such as the operation of the push-off device, are started and controlled. However, this type of operating device does not offer any possibility of displaying, for example, actual values, nominal values or items of maintenance advice to the operator.

[0004] In the prior art, a take-up winder having a touch-sensitive screen by which an operating device can initiate control commands by so-called touch technology key strokes is known, for example, from German Patent Application Publication No. 10250442. However, this type of touch-sensitive screen in a machine environment, particularly in a melt spinning facility, is directly exposed to environmental conditions such as spin finish mist, etc., so the lifespan of this type of touch-sensitive screen in the machine is limited. Furthermore, it is not possible to harmonize certain safety-related operating elements, such as an emergency stop, with the touch-sensitive screen.

[0005] Therefore, an object of the present invention is to improve the conventional take-up winder so that, apart from a flexible operating ability, additional information exchange with the operator becomes possible.

[0006] According to the present invention, this object is achieved in that the operating device is composed of an operation panel fixedly held on a machine frame, which has position-fixed control keys, and a movable operation panel having a keyboard.

[0007] Advantageous improvements of the present invention are defined by the features of the dependent claims and combinations of these features.

[0008] The present invention also relates to an operating system for a machine according to German Patent Application Publication No. 102012217576 known from the beverage industry, and it is not obvious even when considering an operating system in which the operating device of the machine can be selectively connected to a holder of the machine or the operator. Depending on the position of the operator, especially when the operating device is removed from the machine, for example, a rapid intervention to switch off the machine cannot be initiated. In this regard, the present invention has the particular advantage that the operating elements essential for the basic functions remain directly fixed to the machine frame of the take-up winding machine. In contrast, auxiliary functions such as, for example, the requirements of a package doffing truck, as well as the display of the operating state and maintenance requirements, can be advantageously assigned to a movable operating panel having a keyboard. In this regard, for example, since pure basic functions such as the start of the process or the replacement of the package are controlled by a fixed operating panel, the operation of the take-up winding machine can be made simple for the operator. The number of control keys on the machine can be minimized. Complicated key stroke combinations for activating auxiliary functions are no longer necessary. The latter can be advantageously integrated into a movable operating panel.

[0009] To avoid operating collisions, it is further provided that the fixed operating panel and the movable operating panel are connected to each other via a control device. Thus, operating errors are eliminated.

[0010] A preferred embodiment of the present invention is that, in order to link the movable operating panel to the control device, the control device is connected to a transmission module, and the movable operating panel can be connected to the transmission module via a wireless connection. This type of transmission module can establish a wireless connection to the movable operating panel, for example, via W-LAN or Bluetooth.

[0011] A particularly advantageous improvement of the present invention is that the transmission module is configured to be switchable for selective activation and deactivation by control keys fixedly positioned on a fixed operation panel so as to prevent overlapping links of a movable operation panel within a single melt spinning facility. Thus, the movable operation panel can be connected to the control device only when the transmission module is activated. When deactivated, the control device is connected only to the fixed operation panel.

[0012] The improvement of the present invention provided is that in the machine frame, a docking station for accommodating a movable operation panel is arranged on the fixed operation panel so that the operator can simultaneously hold all the operation elements of the operating device within the field of view. Thus, the operator can place the movable operation panel within the docking station immediately adjacent to the fixed operation panel.

[0013] Furthermore, here, the docking station may have a plug connection that can directly connect the movable operation panel to the control device. Thus, a wired connection is possible.

[0014] To ensure power supply to the movable operation panel, it is further provided that the docking station has a power transmitter for inductive charging of the movable operation panel. Thus, it is guaranteed that the movable operation panel can be continuously used and that there is no need to place the movable operation panel on any external charging station.

[0015] Here, a particularly advantageous improvement is that the movable operation panel may be selectively connectable to an adjacent control device. Thus, multiple take-up winders within a single spinning facility can be directly and selectively controlled by the movable operation panel.

[0016] To have sufficient potential for visualizing the operating status and maintenance advice items, the movable operation panel is preferably composed of a tablet PC equipped with a touch screen. Therefore, it is preferable to use a commercially available tablet PC.

[0017] The take-up winder according to the present invention will be described in more detail below by way of exemplary embodiments with reference to the accompanying drawings.

[0019] The first exemplary embodiment of the take-up winder according to the present invention is shown in a plurality of FIGS. 1 and 2. A side view is schematically shown in FIG. 1, and a front view of this exemplary embodiment is shown in FIG. 2. Unless explicitly referred to any of the figures, the following description applies to all figures.

[0020] The take-up winder in this exemplary embodiment has a total of four winding positions 6.1 to 6.4 for winding four yarns 24 to form a package 10. The number of winding positions 6.1 to 6.4 is exemplary. Therefore, in the melt spinning process, in order to form a plurality of packages 10, it is common for 10, 12 or more yarns to be wound side by side and parallel on a driven winding spindle 3.1.

[0021] In the exemplary embodiment, the winding positions 6.1 to 6.4 are arranged side by side along the winding spindle 3.1 on the machine frame 1. The winding spindle 3.1 is held protruding into the winding turret 2. The winding turret 2 is mounted so as to be rotatable within the machine frame 1. The rotational movement of the winding turret 2 within the machine frame 1 is effected by the turret drive 5. A second winding spindle 3.2, which is arranged offset by 180°, is also held protruding into the winding turret 2. Two spindle drives 4.1 and 4.2 are respectively assigned to the winding spindles 3. and 3.2. The winding turret 2 having the winding spindles 3.1 and 3.2 can be moved by the turret drive 5. Thus, the winding spindles 3.1 and 3.2 can be alternately guided to an exchange area for doffing the fully wound package 10 and an operating area for winding the yarn 24.

[0022] In the illustrated operating situation, the winding spindle 3.1 is located in the operating area for winding the yarn 24 to form the package 10, and the winding spindle 3.2 having the fully wound package 10 is located in the exchange area for doffing the package 10.

[0023] The winding spindles 3.1 and 3.2 in the operating area interact with a crimping roller 7 extending along the winding positions 6.1 to 6.4. A traversing device 8 is provided for depositing the yarn, and this traversing device 8 has one traversing unit for each winding position. One separate deflector roller 9 is assigned to the traversing device 8 upstream of each winding position. The deflector roller 9 is held rotatably free on a displaceable roller support 22. The deflector roller 9 functions to separate the yarns 24, and these yarns 24 are guided as one yarn group in the melt spinning process and are drawn off by godets.

[0024] For this purpose, in this exemplary embodiment, two godets 20.1 and 20.2 are held by a godet support 25. The godet support 25 and the roller support 22 are supported by a machine frame 1. On the opposite side of the godet support 25, the godets 20.1 and 20.2 are respectively connected to one godet drive 21.1 and 21.2.

[0025] In order to push away the fully wound package 10 around the decelerated take-up spindle 3.2 or 3.1, a push-away device 18 is arranged in the lower region of the machine frame 1. The push-away device 18 has a slider which can be displaced in the axial direction of the take-up spindles 3.1 and 3.2 by a pneumatic linear drive 19. Therefore, the slider can be guided to reciprocate between a stop position and an advanced end position.

[0026] An operating device 11 including a fixed operating panel 11.1 and a movable operating panel 11.2 is provided for operating the take-up winder. The fixed operating panel 11.1 has fixed control keys 14 and is arranged on the end side of the machine frame 1. A docking station 12 to which the movable operating panel 11.2 can be docked is configured on the machine frame above the fixed operating panel 11.1.

[0027] As derived from the diagrams of FIGS. 1 and 2, the transmission module 16 is arranged on the machine frame 1. The transmission module 16 is connected to the control device 13. Further, control keys on the fixed operation panel 11.1 are arranged on the transmission module 16 to activate (turn on) and deactivate (turn off) the transmission module 16. The transmission module 16 establishes a wireless connection to the movable operation panel 11.2. Thus, the movable operation panel 11.2 can be wirelessly connected to the control device 13 via, for example, a W-LAN connection or a Bluetooth connection. The fixed operation panel 11.1 is connected to the control device 13 by a wired connection. Further, the control device 13 is connected to the drive devices 4.1, 4.2, 5 and 19, actuators of further auxiliary devices (not shown here), and sensors.

[0028] The operating devices 11 in FIGS. 3.1 and 3.2 are shown in different operating situations. In this regard, further reference is made to FIGS. 3.1 and 3.2.

[0029] In the operating situations shown in FIGS. 2 and 3.1, the movable operation panel 11.2 is held by the operator. The docking station 12 of the machine frame is empty. A plurality of control keys 14 are provided on the fixed operation panel 11.1 so that the operator can directly execute the basic functions with the take-up reel. In particular, safety-related control keys such as, for example, an emergency on / off switch are also provided on the fixed operation panel 11.1.

[0030] As can be understood from FIG. 3.2, the movable operation panel 11.2 has, for example, a keyboard 15 that can represent a plurality of digital control keys and display areas. In the situation shown in FIG. 3.2, the movable operation panel 11.2 is arranged at the docking station 12 of the machine frame 1, whereby this movable operation panel 11.2 can be operated in combination with the fixed-position operation panel 11.1 by one operator in order to control the drive device and the actuator. For example, auxiliary actions such as requiring a package docking device can be initiated here, in particular, by the keyboard 15 of the movable operation panel 11.2. Furthermore, for example, the actual states of godets 20.1 and 20.2 can advantageously be directly displayed on the movable operation panel 11.2. Here, the connection between the movable operation panel 11.2 and the control device 13 is likewise made at the docking station 12 via a wireless connection to the transmission module 16.

[0031] However, alternatively, there is also the possibility of a plug connection 17, which enables a direct connection between the movable operation panel 11.2 to be placed within the docking station 12 and the control device 13. For this purpose, the plug connection 17 is shown by a dashed line in FIG. 3.1.

[0032] The movable operation panel 11.2 of the operating device 11 is preferably configured as a tablet PC having a touch screen. The alternative configuration of the docking station 12 of the machine frame 1 here is particularly advantageous for ensuring the availability of the movable operation panel 11.2. For this purpose, an alternative embodiment of the docking station 12 at the end side of the machine frame 1 of a further exemplary embodiment is schematically shown in FIG. 4. In the exemplary embodiment shown in FIG. 4, a power transmitter 23 is attached to the docking station 12 to enable inductive charging of the movable operation panel 11.2. Thus, the operation panel 11.2 can be inductively charged whenever this operation panel 11.2 is arranged at the docking station 12.

[0033] The take-up winder according to the present invention is first distinguished in that all basic mechanical functions for operating the winding position are directly retained in the machine by a position-fixed operation panel. Thus, in particular, safety-related control elements such as, for example, an emergency on / off switch can be actuated directly on the operation panel on the machine.

[0034] In contrast, for example, requirements for a package doffing track for removing a complete package, or auxiliary functions such as maintenance advice or items of operating status can advantageously be indicated on a movable operation panel. Thus, an operator using a movable operation panel may control a plurality of take-up winders within one melt spinning facility with the movable operation panel. Due to the switching ability of the transmission module, it is ensured that the movable operation panel is connected to only one of these take-up winders.
