Definitions
- the invention relates to a winding machine according to the preamble of claim 1.
- Such a winding machine is known from DE-PS 32 43 994.
- the separating device With the separating device provided there, a reliable severing of the web at a defined point is to be achieved, so that the web start created thereby has a sufficient length for fastening to a new winding tube.
- the separating device must therefore be arranged at a point on the lowering table where it can engage the web running between the roller and the winding roll located on the lowering table.
- the separating device must not hinder the transition of the winding roll from the roller to the discharge table. In addition, it must not cause any damage to the outer layers of the winding roll.
- the separator must be easily accessible for maintenance purposes.
- the separating device must be arranged so that injuries to the operator of the winding machine can be safely avoided.
- the object of the invention is therefore to meet these partially contradicting requirements when designing a structurally simple separating device.
- the solution is advantageous in that the separating device is accommodated in the discharge table when not in use (rest position), where it does not interfere with the transfer of the winding roll to the discharge table and is out of the way of easy access, so that accidents can be avoided safely.
- the separating device can be brought into a position (working position) in which it is particularly effective and a safe separation of the web is achieved.
- the measure specified in claim 1 produces a stable mounting of the separating device on the drain table on the one hand and a protected arrangement of the strip with separating element on the other hand.
- an unobstructed transfer of the winding roll is achieved without damaging the web layers.
- the actuating device characterized in claim 4 fulfills the purpose of moving the separating device into its two positions with little design effort. Significant forces cannot be applied, so that a relatively small pneumatic unit is sufficient for this.
- the winding machine designated by number 10 in FIG. 1 has a central roller 11 and on both sides of this a respective auxiliary roller 12 and 13 running in parallel.
- the rolls 11 and 12 and 11 and 13 each form a winding bed 14 and 15 in their upper gusset.
- a web 16 fed to the central roller 11 from below is cut into two web strips 16.1 and 16.2 by a longitudinal cutting device, not shown.
- These strips 16.1. and 16.2 are wound into a respective roll 17 and 18 in the corresponding winding bed 14 or 15, namely the web strip 16.1 running from above into the winding bed 14 via the central roller 11 to the winding roll 17, while the strip running from below into the winding bed 15 16.2 the winding roll 18 is manufactured.
- the winding bed 15 is associated with a device 19 which can be moved in from underneath the auxiliary roller 13 to separate the strip 16.2 from the web 16.
- a separation device 19 is described in detail in DE-PS 31 09 587.
- each auxiliary roller 12 and 13 there is a discharge table 21 and 22 respectively for receiving the finished winding rollers 17 and 18 when changing the winding.
- 11 ejection levers 23 and 24 are arranged above the central roller.
- the winding rollers 17 and 18 are rolled over the corresponding auxiliary roller 12 and 13 and rolled into the respective discharge table 21 and 22 shown in its receiving position.
- the discharge tables 21 and 22 can be moved in the direction of the arrow in order to deposit the winding rolls 17 and 18 from the machine 10.
- the levers 23 and 24 are provided with collets 25 and 26, respectively, with which they can accommodate new winding tubes 20 (in the position 20 ') after returning in the direction of the arrow to their rest position.
- These new winding tubes 20 are provided on a rail 27 running above the central roller 11.
- clamping heads not shown
- the collets 25 and 26 are lowered into the respective winding bed 14 and 15, respectively.
- Such machine equipment for sleeve input is known from DE-PS 35 40 490. Otherwise, the basic structure of the winding machine is described in detail in the aforementioned DE-PS 32 43 994.
- the winding machine 10 is also equipped with a device 28 arranged along the edge region of the discharge table 21 near the rollers for separating the winding rolls 17 from the web strip 16.1, which runs towards the winding bed 14.
- the separating device 28 is embedded in a plate 29 of the discharge table 21 which supports the winding roller 17.
- the support plate 29 has in its edge region near the roller a machine-wide recess 30 in which a strip 31 running parallel to the roller 12 also has a plurality of concealed hinges 32, which are distributed over their entire length and are screwed to the support plate 29, are pivotably mounted.
- an element 33 for separating the web strip 16.1 running between the central roller 11 and the winding roll 17 located on the discharge table 21 is fastened with screws 34.
- the separating element 33 consists of a toothed blade which is expediently divided into several individual elements over the machine width of several meters. A saw wire, a hot wire or a knife blade can also be used as the separating element.
- the separating device 28 is connected to an actuating device 35.
- the strip 31 of the separating device 28 is provided at at least one of its two ends with a lever arm 36, on which a pneumatically actuatable piston-cylinder unit 37 mounted on the discharge table 21 engages with its piston rod 38.
- the bar 31 is in its rest position drawn with dash-dotted lines in FIG. 2. In this position, the bar 31 together with the separating element 33 is completely received by the recess 30, so that the upper side of the bar 31, via which the winding roller 17 rolls when removed from the machine 10, is flush with the corresponding side of the support plate 29.
- the separating device 28 With the actuating device 35, the separating device 28 can be moved into its working position (shown in solid lines in FIG. 2).
- the strip 31 with its separating element 33 comes out of the recess 30 of the drain table 21 and, in the position mentioned, makes an angle of approximately 60 ° to the upper side of the support plate 29.
- the finished winding rolls 17 and 18 with the ejection levers 23 and 24 are rolled out of the respective winding bed 14 and 15 over the auxiliary rollers 12 and 13 onto the corresponding discharge tables 21 and 22 when the machine is at a standstill.
- the separating device 19 has just been brought into its working position shown in FIG. 1.
- the winding roll 18 is therefore already separated from the web strip 16.2.
- Negative pressure in the central roller 11 with a perforated jacket holds this web strip firmly on the roller, so that the separating device 19 can be moved in the direction of the arrow from the winding bed 15 in order to insert a new winding tube 20 there and connect it to the web strip 16.2.
- the separator 28 When moving the winding roller 17 from the winding bed 14 to the discharge table 21, however, the separator 28 is in its rest position. As soon as the winding roll 17 assumes its end position shown in FIG. 1 on the discharge table 21, the separating device 28 is brought into its working position with the actuating device 35. The separating element 33 of the separating device 28 engages on the web strips 16.1 which extend from the central roll 11 via the winding bed 14 and the auxiliary roll 12 to the finished winding roll 18. The web strip 16.1 can be separated by lowering the new winding tube 20, which is gripped by the clamping heads, into the winding bed 14. The winding sleeve 20 engages and tightens the web strip 16.1, so that the separating element 33 penetrates with its teeth into the web strip and perforates it. The further movement of the new winding tube 20 leads to the severing of the web strip 16.1 along the separating element 33.
- the separation process can also be brought about by pivoting the discharge table 21 in the direction of the arrow.
- the web strip 16.1 is tightened and on the separating element 33 Cutting device 28 severed.
- the central roller 11 is held in the braking position in both variants of the separating process and the rail 27 is placed on the roller in order to hold the web strip there.
- the attachment of the new web start of the web strip 16.1 formed in this way to the new winding tube 20 can be done by gluing, tacking or the like. respectively.
- the winding machine 10 is ready for winding again after the winding rollers 17 and 18 have been put down.
- the separation device 28 described can not only be used in winding machines 10 with three rollers 11, 12 and 13. Can be used on machines with two rollers (so-called double carrier roller winding machines) or also on machines with only one roller (so-called backup roller winding machines). It is not necessary to split the incoming web into strips in such machines.
- the cutting device described can also be used to cut a full width of a web.
