Devices for turning a sheet

The invention relates to devices for turning over a sheet according to the preamble of claims 1, 2 or 4th

From DE 195 02 240 C2 a paper web turning device in conjunction with a paper web feeding apparatus is known by means of which is conveyed via a turning bar, a beginning of a paper web. The turning bar is surrounded by a jacket-like web leads. The coat-like paper web guide has blowing holes through which the paper web start blown on its side remote from the turning bar and is pressed to the turning bar.

DE 197 23749 A1 describes a guide roll with directly arranged in front of suction belts.

DE 39 14 310 C2 shows a turning bar with a guiding device. This guide includes a plurality of suction chambers.

The DE 43 35473 A1 discloses a turning device with transport means which are movable together transversely to the transport direction.

The invention has the object to provide devices for turning a path that lead a path secure around a turning bar.

The object is solved by the features of claims 1, 2 or 4th

The advantages achieved with the invention consist in particular in that an incoming web drawn with draw-in speed of the adjustable driven suction belts and secure a guide means is supplied. In the guide device, the web is easily led to the turning bar, wherein the inlet to and the outlet from the guide beblasbar voids are formed by controllable compressed-air nozzles or.

By combination of left and right turning units, which are movable transverse to the machine longitudinal axis, all the production-related web paths may be covered.

An embodiment of the invention is illustrated in the drawing and will be described in more detail below.

Show it:

Figure 1 is a plan view of a turning device having two turning units.

2 is a view A on a left turning unit of Figure 1, partly in section..;

Fig. 3 is a view B of Figure 1, partly in section, with the left and right turning unit of the turning device is located in the working position.

Fig. 4 is a turning unit with folded-out guide, z. As for bay-window operation;

Fig. 5 is a turning unit with folded-out guide, z. As for a straight running rail.

A turning device consists of one or more such. B. two turning units 01; 02. The turning units 01; 02 are moved back and arranged herverfahrbar in the transverse direction C to the machine longitudinal axis 03. Each inverter unit 01; 02 is in a different plane, z. B. an overhead plane D for the turning unit 01 and a parallel to the underlying plane E for the turning unit 02 is disposed.

The turning units 01; 02 are respectively arranged on a frame 04 or 06, which on both sides, z. B. rails 07; 08 or 09; siege 11 and is moved by means of linear drives. The linear drives are made for. B. from rack mounted fixed, rotatable threaded spindles 33; 34 with unillustrated motor drives for moving the turning units 01; 02 in the transverse direction C to the machine longitudinal axis 03.

Each inverter unit 01; 02 has, in the web running direction F of a sheet 12, for. seen as a paper web 12, a transport device 13, z. For example, a web supply-suction table 13, a luftumspülbare turning bar 14 and 20 with a partially surrounds this guide means 15, for. B. a Papierleitkammer 15 as well as a transport device 16, z. For example, a web-dissipating suction table 16.

The web supply-suction table 13 and the web-dissipating suction table 16 of each reversing unit 01; 02 consists of a web arranged in the movable frame 04 or 06 web widths, with holes 17 provided unterdruckbeaufschlagbaren upper and lower suction box 18; 19 with air supply 25; 30. Each of the suction boxes 18; 19 has a plurality of z. For example, four in each case with their upper run 21 on the surface 22 of the suction boxes 18; 19 frictionally movable, endless circulating, 23 and 24 can be driven by a variable speed motor suction belts 26; 27. The suction belts 26; 27 are provided with holes 31 and are parallel and spaced from one another around guide rollers 28; 29. The suction belts 26; 27 of the paper web 12 run in each case with their upper strand 21 about in the web running direction F. Is always a number of holes 31 with the under the suction belts 26; 27 in the suction boxes 18; 19 holes located 17 in operative connection.

This ensures that the beginning of the recovered paper web 12 is always sucked.

The web supply-suction table 13 ends in front of the turning bar 14. The angle bar 14 is known to be tubular and is acted upon by its interior space with blast air exit which referring in the radial direction of holes 32 through a circumference of 180 ° and a paper web 12 thus during the drawing-supported and can slide below during the production process.

viewed in the web running direction F of a paper web 12 of the web-dissipating suction table 16 is followed by the turning bar 14, which is arranged offset relative to the web supply-suction table 13 by 90 °.

The turning bar 14 surrounding Papierleitkammer 15 is bounded at its periphery by a turning bar 14 at a radial distance g, coaxially arranged for blowing region of the turning bar 14 channel-shaped intermediate wall 36th n which holes are introduced 37th

The intermediate wall 36 is adjacent to a suction chamber 38, which in turn is 180 ° g surrounded coaxially at a radial distance from a channel-shaped casing. 39 The suction chamber 38 is connected to a suction conduit 41 which leads to a not shown Saugluftstation.

The paper web 12 promotional upper run 21 of the suction belts 26; 27 is formed on its side, the paper web 12 and conveying in papierleitkammernähe blasluftbeaufschlagbar. This is done by in the vicinity of the Papierleitkammer 15, ie the end of the web supply-suction table 13 and the beginning of the web-dissipating the suction table 16 by the suction belt 26; 27 blowing chambers located 42; 43. In this case, there is a foraminous 40 Blaskammerblech 45; 50 at a distance g on the suction belt 26; 27. The blowing chambers 42; 43 are respectively connected to flexible Blasluftleitungen 44; 46 is connected.

The blowing chambers 42; 43 may be each formed by an extension of the intermediate wall 36 as well as the trough-shaped housing 39, wherein between the suction chamber 38 and the blowing chambers 42; 43, a partition wall 47; is inserted 48th

The devices for turning a sheet functions as follows:. The infeed in a rotary unit 01 of Figures 1 and 3 top of the paper web 12 is applied and by the driven suction belts 26 of the web supply-suction table 13 is supplied to the beblasenem from the puffer chamber 42 the input of the Papierleitkammer 15 , The beblasene turning bar 14 directs the beginning of the paper web 12 to the beblasenen from the puffer chamber 43 the output of the Papierleitkammer 15 and passes the beginning of the paper web 12 below the suction belts 27 of the web-dissipating suction table 16 for forwarding to the turning unit 02.

There, the paper web is conveyed in the same way 12, so that they turned 180 ° and the web width enables the turning units 01; may leave 02.

Outside the webbing process, ie during the production of the suction chamber can be put into operation 38, so that the resulting paper dust can be sucked.

According to another embodiment, the one-piece Papierleitkammer shown in Fig. 4 and 5, 15 and the suction chamber 38 is formed in two parts. Two half-length, ie 90 ° separated the turning bar 14 or 20 surrounding the partitions 49; 51 is provided so that two suction chambers 52; 53 are formed, each of two outer housings 54; be limited 56th Thus, for each suction chamber 52; 53, a separate suction line 57; 58 required.

By means of a shaving Nieres 59 and a drive mechanism not shown, eg. Example by means of a working cylinder or by hand is one of the two suction chambers 52; 53 pivotable at an angle α of 180 ° in a turning bar distant rest position H.

Thus, the paper web 14 can be from 90 ° to leave 12 of FIG. 4 after one wrap of the turning bar, the lateral surface of the turning bar 14.

According to FIG. 5, the suction chamber 52 is folded by the amount of the angle α of 180 ° downwards so that the paper web 12 can run straight, z. As for bay-window guidance or mixed operation of paper webs.
