Description

Technical Field

[0001] This invention relates to a flip-type winding machine, particularly a flip-type winding machine for printing presses. Furthermore, this invention relates to a system incorporating such a flip-type winding machine and a method for manufacturing windable products. Background Technology

[0002] For example, a reversible winding machine used in printing presses is particularly used to roll up (wrap up) printed matter produced by means of a printing press, or to unwind (unwind) the web of material supplied to the printing press as a material roll.

[0003] For this purpose, the flip-type winding machine has two coil receiving sections, each configured to hold and support the material coil, wherein the coil receiving section is constructed at a swing wheel. The swing wheel is used to swing the material coil from a position facing the printing press (in which the material coil is used by the printing press) to a position away from the printing press (in which the material coil can be replaced).

[0004] The flip-type winding machine has a device for area protection, which is configured to separate the work area accessible to the operator from the machine area inaccessible to the operator. For this purpose, optical systems are typically used, such as photoelectric barriers (Lichtschranke, sometimes called beam-blocking sensors).

[0005] Known flip-type winding machines typically have a fixedly mounted photoelectric barrier for zone protection, protecting the entire oscillation area of ​​the winding machine, i.e., the oscillating wheel along with the material coil it houses. Furthermore, such flip-type winding machines typically have a second photoelectric barrier and a mechanical barrier for additional zone protection, arranged between the coil housings of the oscillating wheel. This additional zone protection protects the material coil located during operation and facing the printing press relative to the external winding section or coil housing.

[0006] The disadvantage is that the use of two separate systems for area protection, and especially the area protection device located between the coil housings, makes it difficult to access and maintain the oscillating wheel. Summary of the Invention

[0007] Against this backdrop, the technical problem of the present invention is to provide a flip-type winding machine capable of reliably achieving area protection, particularly an area protection device with fewer parts and / or occupying less structural space. Furthermore, a system incorporating such a flip-type winding machine and a method for manufacturing windable products should be provided.

[0008] The aforementioned technical problems are solved by the features of the independent claims. Other embodiments of the invention are derived from the dependent claims and the description below.

[0009] According to a first aspect, the present invention relates to a flip-type winding machine having two coil receiving portions respectively configured to hold and support material coils, wherein the coil receiving configuration at the oscillating wheel includes a device for area protection, wherein the device for area protection is configured to separate a work area accessible to the operator from a machine area inaccessible to the operator. The flip-type winding machine thus excels in that the device for area protection has a scanner that can travel along an axis.

[0010] A mobile scanner replaces the photoelectric barrier described at the beginning, as well as the photoelectric barrier along with its mechanical fence arranged between the two coil receptacles. This eliminates the need for the area protection components arranged between the coil receptacles, freeing up structural space and improving accessibility for maintenance and installation. The photoelectric barrier protecting the entire swing area can also be eliminated, allowing the area protection device described at the beginning to be completely replaced by the mobile scanner.

[0011] According to one design of the flip-type winding machine, apart from the scanner that can travel along the axis, no additional devices for area protection, such as fixed photoelectric barriers, are installed.

[0012] Therefore, the scanner and the shaft together construct a dynamically positionable photoelectric barrier, which can be positioned according to the operating mode of the flip-type winding machine in order to protect different areas.

[0013] The working area and the machine area can be configured such that, for a first operating mode, the scanner is arranged at a first position on the axis, and the oscillating wheel and the material coil are fully arranged within the machine area; and for a second operating mode, the scanner is arranged at a second position on the axis, and the oscillating wheel is not fully arranged within the machine area, one of the coil receiving parts is arranged within the machine area, and one of the coil receiving parts is arranged outside the machine area but within the working area.

[0014] Accordingly, in the first operating mode, the entire swing range of the oscillating wheel, along with the two winding sections or coil receiving sections, is protected by the scanner, or, from the operator's perspective, is located behind the scanner's scanning plane. In the first operating mode, when viewed in the longitudinal direction of the axis, the scanning plane is at a distance from the oscillating wheel.

[0015] In the second operating mode, only one of the coil receptacles, more specifically the one facing the printing press, is protected by the scanner, or, from the operator's perspective, is located behind the scanner's scanning plane. Therefore, the operator-facing coil receptacle is easily accessible for handling and installation work. In the second operating mode, the scanner's scanning plane extends between the coil receptacles of the oscillating wheels.

[0016] The scanner can be configured for personnel identification and is coupled to an emergency stop function. Therefore, if personnel enter the machine area, it triggers a machine stop or an emergency stop.

[0017] Previously, regarding specific flip-type winding machines, a distinction was made between the machine area and the work area, specifically mentioning that personnel "enter" these areas. Here, the term "enter" includes not only walking on the relevant area by personnel or operators, but also any intervention by personnel within that area and any reaching or touching of the area. In other words, any movement of a person's hand, arm, head, or foot across or intruding into the boundary of the relevant area is considered entry.

[0018] When it is mentioned that the material coil is supported at the tilting winder, it means that the material coil is supported at the frame of the tilting winder in a manner that allows it to rotate about the axis of rotation.

[0019] In particular, the material coil can be automatically inserted into the relevant support of the rotary winding machine, and can also be automatically removed from the rotary winding machine. Corresponding systems for automatic coil replacement are known.

[0020] The corresponding coil receiving section can be respectively configured to receive material coils with a width greater than 50cm, especially to receive material coils with a width greater than 100cm, and even more particularly to receive material coils with a width less than or equal to 250cm.

[0021] The corresponding coil receiving section can be configured to accommodate material coils weighing more than 100 kg.

[0022] The material reel may have a sleeve or winding shaft configured to receive the material web. The sleeve or winding shaft of the material reel particularly has end sections facing away from each other, through which the material reel is placed in the reel receiving portion. Such sleeves or winding shafts may be made of metal.

[0023] The material web of the material reel can be a multi-layered material web or a single-layered material web. The material web of the material reel can have one or more layers made of paper and / or plastic film and / or metal film.

[0024] The thickness of the material sheet can be greater than or equal to 5 μm or 10 μm, especially greater than or equal to 25 μm, and even more especially less than or equal to 1 mm.

[0025] The scanner can travel along an axis. The axis can be a controlled axis, especially a numerically controlled axis.

[0026] The scanner's travel path can be defined as a straight line, thus allowing the scanner to travel in a purely linear manner. According to alternative designs, the scanner's travel path can be defined as an arc or a wavy profile. It is evident that, for success according to the invention, all that is required is that the scanner can occupy different defined positions or travel between different defined positions, where the type of travel path is secondary. The scanner can be held oscillatingly and can oscillate about an axis or along an oscillation path.

[0027] The axis used to move the scanner can be a linear axis, such as a ball screw pair, toothed belt shaft, rack shaft, pneumatic linear axis, etc.

[0028] The scanner can be held, in particular, at a travelable slide on the linear axis by means of a retainer. The retainer may have, in particular, one or more plate members, which may be releasably connected to the travelable slide, for example, by a swivel joint.

[0029] The linear shaft can be fixed to a fixed frame of the rotary winding machine. Specifically, the linear shaft can be releasably connected to the fixed frame of the rotary winding machine, for example, by screwing. The linear shaft can be fixed to the fixed frame of the rotary winding machine by means of a shaft retainer. The shaft retainer may, for example, be a sheet material, especially a corner-shaped sheet material.

[0030] Viewed from above, the linear axis can be arranged perpendicular to the rotation axis of the material reel. This allows the scanner to travel along the entire thickness or diameter of the material reel. The length of the linear axis can be configured to exceed the maximum permissible thickness of the material reel.

[0031] According to one design of the flip-type winding machine, when viewed vertically, the linear shaft and the mobile scanner are arranged above the material coil, especially when viewed and measured from the workshop floor above the flip-type winding machine, which is arranged more than 2m above the workshop floor.

[0032] The shaft may have a device for determining the scanner's axial position along the shaft, such as a rotary encoder or displacement encoder. Some shafts have a displacement measurement system integrated into the shaft structure. However, it is also possible to configure the shaft for use in conjunction with a separate device for determining the shaft's position.

[0033] For example, the device for determining the axial position of the scanner can be configured to have a fixed rack and a pinion that travels with the scanner, wherein the pinion engages with the rack and wherein the pinion is associated with a rotary encoder to determine the longitudinal position of the scanner along the rack according to the measured rotation of the pinion.

[0034] For example, the shaft can be configured as a pneumatically travelable linear shaft with a corresponding travelable slide, at which the scanner is held. Similarly, the aforementioned pinion can be combined with a corresponding rotary encoder and held at the slide to acquire the scanner's position along the linear shaft according to the number of rotations of the pinion engaging with the associated rack. Needless to say, the rack extends parallel to the longitudinal direction of the linear shaft or the linear travel displacement.

[0035] It can be configured so that the scanner can travel along a road segment with an axis greater than or equal to 100cm and less than or equal to 400cm.

[0036] The scanner can be a laser scanner, particularly one that covers a scanning angle of 180° or greater, and especially one that covers a scanning angle of 270° or greater. Alternatively or additionally, the laser scanner can be configured to have a range of action of greater than 2m and less than 5m.

[0037] According to one design of a flip-type winding machine, the device for area protection can be configured to measure the diameter of the material coil.

[0038] Known devices used in flip-type winding machines for measuring the diameter of material coils include distance sensors or spacing sensors that perform optical measurements, such as laser spacing sensors. However, laser spacing sensors are not suitable for opaque or high-gloss materials. Therefore, depending on the material characteristics of the coil, manual user intervention is required to obtain the initial diameter, or for synchronization or coil changing.

[0039] Fixed distance sensors or point sensors are only suitable for exploring a single point of the outer diameter of the material roll and determining the corresponding distance, from which the diameter of the material roll can be calculated. However, specific devices with scanners that can travel along an axis are suitable for acquiring multiple measurement points of the circumference or outer contour of the material roll in general, so as to achieve a significantly more reliable and accurate determination of the circumference of the material roll.

[0040] In addition to determining the diameter of the material coil, the scanner can also be configured to determine the diameter of the sleeve or winding shaft of the material coil.

[0041] According to another aspect, the present invention relates to a system for manufacturing machines for windable products, such as printing presses for manufacturing printed products, extrusion equipment for manufacturing film products, hose machines for manufacturing hose products, etc., equipped with a reversible winding machine for winding or unwinding material coils, wherein the reversible winding machine is constructed according to the invention. The system can be configured such that it has not only a reversible winding machine for winding material coils but also a reversible winding machine for unwinding material coils, both of which can be designed according to the invention.

[0042] According to another aspect, the present invention relates to a method comprising the steps of: manufacturing a rollable product by means of a system according to the invention, wherein a scanner is used to monitor a machine area, wherein if a person is detected in the machine area, the scanner triggers the machine to stop, in particular by means of an emergency stop function.

[0043] In the case of a scanner also used to measure the diameter of a material roll, one design of the method includes the following steps: measuring the diameter of the material roll by means of a mobile scanner, wherein the scanner is moved by means of an axis during the measurement.

[0044] The invention will now be described in more detail with reference to the accompanying drawings illustrating the embodiments.

Detailed Implementation

[0045] Figure 1 A flip-type winding machine 1 according to the present invention is shown, having a first winding receiving portion 2 and a second winding receiving portion 3. For the sake of simplicity in the following description, a Cartesian coordinate system x, y, z is introduced.

[0046] The first coil receiving portion 2 and the second coil receiving portion 3 are respectively used to hold and support the respective associated material coils, wherein, in the current illustration, the material coils are not respectively arranged in the relevant coil receiving portions 2 and 3.

[0047] The coil receiving portions 2 and 3 are constructed at the oscillating wheel 30, which can oscillate around the axis 32 by means of the driver 31 for coil replacement. The oscillating wheel 30 and the driver 31 are provided with external teeth and are in tooth engagement with each other.

[0048] The flip-type winding machine 1 has a device 4 for area protection. The device 4 for area protection is also a device 4 for measuring the diameter of the material coil.

[0049] Device 4 has a scanner 6 that can travel along axis 5.

[0050] Currently, axis 5 is a pneumatically linear axis 5. The following text follows... Figure 2 and Figure 3 The structure of the device 4 for area protection is described in more detail. The device 4 for area protection... Figure 2 The device 4 for area protection is shown separately and in an enlarged perspective view. Figure 3 It is shown separately in a side view.

[0051] The pneumatic linear shaft 5 is associated with a device 7 for determining the axis position of the scanner 6. Figure 3 ).

[0052] The device 7 for determining the axis position of the scanner 6 has a rotary encoder 8, a pinion 9, and a rack 10.

[0053] The rack 10 and the linear shaft 5 are fixedly connected to the frame 11 of the flip-type winding machine 1 and are oriented parallel to each other when viewed along its longitudinal direction.

[0054] The pinion 9 engages with the rack 10 and is held at the shaft 12 of the rotary encoder 8. The rotary encoder 8 and the scanner 6 are jointly secured to the travelable slide 13 of the pneumatic linear shaft 5 by means of a retainer 20.

[0055] If the movable slide 13 of the pneumatic linear shaft 5 now travels along the longitudinal extension L of the linear shaft 5 (parallel to the x-axis), its linear translational motion is converted into rotation of the shaft 12 of the rotary encoder 8 through the rolling tooth engagement between the pinion 9 and the rack 10. Due to the known gear geometry, the longitudinal position of the scanner 6 in the x-direction can be determined according to the measured rotation angle of the rotary encoder 8.

[0056] The pneumatic linear shaft 5 has two mutually spaced end positions 14 and 15. End positions 14 and 15 can also be referred to as end points. Each end position 14 and 15 is associated with a device 16 and 17 for end position lookup.

[0057] The device 16 for end position query has a position-fixed component 18 in the form of a switch flag 18. The device 16 for end position query also has a component 19 in the form of an electronic trigger 19 that can travel by means of a shaft 5. The trigger 19 is fixed at a retainer 20, where the rotary encoder 8 and the scanner 6 are also fixed.

[0058] The device 17 for end position query has a component 21 that is fixed in position in the form of a switch flag 21. The device 17 for end position query also has a component 22 that is movable by means of a shaft 5 in the form of an electronic initiator 22. The initiator 22 is also fixed at the retainer 20.

[0059] With regard to the travelable slide 13 reaching one of the end positions 14 and 15, the switch flags 18 and 21 associated with the relevant end position 14 and 15 are respectively located directly in front of the triggers 19 and 22 associated with the relevant end position 14 and 15 on the end side, which triggers detect the associated switch flags 18 and 21 and indicate arrival at the relevant end position 14 and 15 in this manner.

[0060] The switch flag 21 is fixed to the shaft retainer 23, which also carries the shaft 5 and the rack 10. The shaft retainer 23 is fixed to the frame 11.

[0061] In addition, a cable drag chain 24 or energy chain 24 is provided, which is secured to the frame 11 by an additional retainer 25. One end of the energy chain 24 is connected to the retainer 20, thereby guiding it in the longitudinal direction L. The energy chain 24 is used in a known manner to guide the circuitry that is necessary for and connected to the operation of the scanner 6, rotary encoder 8, and initiators 19, 22.

[0062] The retainers 20, 23, and 25 may have shaped sheet metal and / or angle metal.

[0063] As from Figure 1As is known, scanner 6 covers a scanning plane S that extends substantially parallel to the yz plane, which is schematically represented by dashed lines emanating from scanner 6.

[0064] Scanner 6 can travel more than 100 cm along the road segment parallel to the x-direction using axis 5. Therefore, Figure 2 The longitudinal extension length L shown is greater than 100cm.

[0065] Scanner 6 is a laser scanner 6, which is suitable for covering a scanning angle greater than 90°. Laser scanner 6 has an operating range greater than 2m and less than 5m.

[0066] Figure 4 Linear axis 5 is shown, with scanner 6 located at end position 15, which is queried via device 17 for position query by means of switch flag 21 and trigger 22. Figure 4 Next to the right side of the presented scanning plane S, there is a work area or operation area 26 where personnel stay.

[0067] Figure 4 The material coil 27 housed in the coil receiving section 2 is shown. The material coil 27 has a sleeve 28, which may also be referred to as a winding shaft, on which the material web 29 is wound.

[0068] In order to measure the diameter d of the material coil 27, the scanner 6 travels at a constant speed in the direction of the material coil 27 by means of the linear axis 5, wherein the position of the scanner 6 in the longitudinal direction or the x-direction is measured by means of the rotary encoder 8.

[0069] Scanner 6 in Figure 5 The outer contour of the material coil 27 was identified in the position shown in the image, and the process continued until... Figure 6 In the position shown, the scanner 6 also identifies the outer contour of the material coil 27. From the position detected by the rotary encoder 8 in the longitudinal or x-direction, the diameter d can be calculated.

[0070] Figure 7 The scanner 6 displays the end position 14, which is queried via the device 16 for end position query by means of the switch flag 18 and the trigger 19.

[0071] The device 4 for area protection separates the work area 26, which is accessible to operators during machine operation, from the machine area 38, which is not accessible to operators during machine operation.

[0072] Depending on the operating status or mode of the flip-type winding machine 1, the working area 26 and the machine area 38 can be different areas, such as... Figure 7 and Figure 4 As indicated in the document.

[0073] Currently, work area 26 and machine area 38 depend on the operating mode definition, where, for Figure 4 The first operating mode presented in the diagram shows that the scanner 6 is positioned at the first position of axis 5, more precisely at end 15 (see [reference]). Figure 1 At this location, the oscillating wheel 30, the material coil 27, and the coil receiving portions 2 and 3 are completely arranged within the machine area 38. According to... Figure 4 When viewed in the longitudinal direction L, the scanning plane S has a distance relative to the oscillating wheel 30.

[0074] For the second operating mode, scanner 6 is positioned at the second position of axis 5, more precisely at end 14 (see...). Figure 1 Therefore, since the scanner 6 has already occupied another position in the x direction and thus the scanning plane S is offset in the x direction, the working area 26 and the machine area 38 are defined differently for the second operating mode than for the first operating mode.

[0075] In the second operating mode, the oscillating wheel 30 is not entirely located within the machine area 38, but is partially located in the working area 26 in a manner accessible to the operator. The coil receiving part 3 is located within the machine area 38, while the coil receiving part 2 is located outside the machine area 38 but within the working area 26. Thus, during operation, while the material coil 35 is being used by the printing press 33, personnel can access the material coil 27 (see [link to printing press]). Figure 8 ).

[0076] Scanner 6 can be configured for personnel identification and coupled with the emergency stop function.

[0077] Figure 8 A printing system 34 is shown schematically and in a highly simplified manner, comprising a printing press 33 for producing printed products and a reversible winding machine 1 for winding or unwinding material coils 27. Since this involves a reversible winding machine 1, another material coil 35 is shown exemplary, which is held and supported in the coil receiving portion 3 of the reversible winding machine 1 by its sleeve 36, wherein the material width 37 of the material coil 35 is used by the printing press 33.

[0078] Therefore, a method can be provided with the following steps: (A) manufacturing a printed product by means of a printing system 34; (B) wherein the diameter d of the material roll 27 is measured by means of a mobile scanner 6, and wherein during the measurement, the scanner 6 is moved by means of a shaft 5; and (C) wherein the scanner 6 is used to monitor the machine area 38, and wherein if a person is detected in the machine area 38, the scanner 6 triggers the machine to stop by means of an emergency stop function.
