Definitions
- the invention relates to a device in the preamble of claim 1 specified type.
- DE 28 53 519 A1 describes a device for stripping a web of material known, which has several threaded spindles.
- the lead screws are rotated by means of a motor so that its threads turn the web pull to the edge.
- a roller is designed pivotable, so that the wrap angle the web around the threaded spindles can be adjusted.
- a similar device is known from US 26 39 483. It has three in a row arranged threaded spindles, which is preceded by a role. The web is removed from a stack from above and redirected at the roller. The web is therefore the threaded spindles approximately in a running through them Level fed. This ensures that the individual threaded spindles are defined in Wrapped around the web and therefore a constant stripping effect exert on the web.
- a web guide is known from WO 91/16258, which has an edge region a web by means of two opposing rollers in the clamping handle detected.
- the rollers are driven to rotate such that the two rollers on the Line of contact with the web at the same speed as the web.
- the axes of the two rollers aligned parallel to one another are of this type held pivotable that they are adjustable with the web running direction, pointed Form an angle. In this way there is a lateral displacement force on the entire web exercised.
- An edge scanning device is arranged downstream of the web guide, which, together with a control device, corrects the web path of the material web enables. To reduce the risk of accidents arising from the pair of rollers is in the area where the roller surfaces are on the line of contact with the web move, a safety device is provided.
- the invention has for its object a device of the aforementioned To create a way that enables a safe and gentle detection of the web, even if the web has holes in the detection area of the device.
- the device according to the invention uses web guiding bodies around the material web keep away from the free ends of the threaded spindles. Become the web guide provided at the point mentioned in claim 1, it is surprisingly simple Way ensured that the web is always tangent to the threaded spindles accumulates. The area B of the web after a hole is through the web guide pushed so far away from the threaded spindle that it is properly tangential is gripped by the threaded spindle. Because there are holes in the web in the free Ends of the threaded spindles can no longer get caught is a gentle and trouble-free operation guaranteed.
- the web guiding bodies are preferably arranged in such a way that they do not affect the course of the properly tapering web, but are spaced from it.
- the web guiding bodies therefore only unfold in Incidents such as holes, tears or sagging of the web have their effect.
- This has the advantage that the material web is not constantly affected by friction, which are caused by the web guiding bodies is braked. Is just a guiding body provided, this is preferably in front of the first threaded spindle in Viewed web direction attached. Especially when the web is bad is tensioned or severely torn at the edge, it preferably threads on the first threaded spindle on.
- the following threaded spindles are due to the low Distance between the spindles reduces the risk.
- it is convenient provide a web guide in front of each threaded spindle. The track is very loose, it can sag between the individual threaded spindles. This could lead to threading the web on one of the threaded spindles, what is reliably prevented by the web guide.
- the application of the feature according to claim 2 is advantageous because the arrangement of the web guide near the threaded spindle, even with large holes in the web a secure grasping of the material web guaranteed by the threaded spindles.
- the guiding section of the web guiding body preferably extends at least to one imaginary normal plane to the incoming web, which is the threaded spindle touched.
- the application is to prevent the web from being threaded into the web guide of the features according to claim 4 advantageous.
- a large distance of the guide section of the web reliably prevents threading of the web on Web guide.
- the formation of the guide section according to claim 5 is particularly favorable since due to the acute angle of the guide section also one is not working properly incoming web is correctly guided to the threaded spindle. Especially if due to an extremely large lateral offset the contact with the Has lost threaded spindles, the guide sections of the web guide body ensure correct re-threading of the web around the threaded spindles. The web run need not be interrupted in this case, so that the productivity of the Device increased.
- a rounded transition between the leading section and the leading section according to claim 6 advantageously ensures correct running of the web, even if it has a hole exactly at the transition between them.
- the rounded transition does not obstruct the web in any way, so that the web the threaded spindle properly even at high running speeds is fed.
- the formation of the web guide body according to claim 7 is inexpensive, since in particular a re-threading of a web that makes contact with the threaded spindles has lost, will be threaded back very securely.
- the viewed from the side sloping guide sections of the web guide body capture the web edge, which is then lifted into its correct position when the web is moved further or is lowered. The material web is re-threaded into the device therefore automatically.
- a particularly inexpensive embodiment of the web guiding body is in claim 8 given.
- An angled rod fulfills with the least material and manufacturing effort the task, so that the entire device by attaching the web guide barely expensive.
- the rods preferably have one round cross-section in order to provide the web with as little resistance as possible.
- a threaded spindle is pivoted to adjust the wrap angle, so the application of the feature according to claim 9 is advantageous.
- a panning of the web guide with the threaded spindle ensures a correct position of the web guide independent of the swivel angle.
- the Material web fed to the threaded spindles particularly gently. Even with deep ones Cracked and heavily sagging material web will properly the threaded spindles fed.
- This configuration of the web guiding body is preferably at Threaded spindles are used, which capture the underside of the web, because sagging webs on these spindles can catch particularly easily. If the guide section covers the threaded spindle axis, the feed of the material web is to the threaded spindles even safer.
- the leading section in in this case, effective protection against contact for the threaded spindle by the operator Person. This reduces the risk of accidents caused by the threaded spindles.
- the web guide body In the formation of the web guide body according to claim 11, this covers one Most of the area of the threaded spindle that is used to strip out the edges of the web is not used. This reduces the risk of accidents caused by the threaded spindles further reduced. Is the web to be spread wet or with impregnated with chemical agents, the web guide has at the point below the Threaded spindle preferably one or more recesses that allow the drainage Allow liquids to drip off the web.
- the formation of the guide section according to claim 12 allows a special inexpensive and safe threading of the web into the threaded spindles. A catch the web during threading on the flat guide section is excluded even if it is torn at this point. By the flat detection of the web with the guide section becomes very kept gently so that damage to even sensitive webs is excluded are.
- the web guide body can be cleaned very easily, which is particularly the case with wet or soaked with chemical agents is important. Furthermore the device can be easily adapted to different operating conditions, if the attachment of the web guide is not desired for a particular web. It when the web guide body by means of a quick attachment is particularly advantageous is set. This reduces the time required to loosen or attach the Web guiding body and thus the committee in the entire production line.
