Definitions

  • the invention relates to a device for forming a roll from a section of a web of flexible material fed from a transport device and cut off at the ends by a cutting device, in particular a job of cutting drawings on paper.
  • cut drawings made by a computer-controlled drawing device have been cut off from the paper web by a cutting device and rolled up by hand and strapped with a band for magazines.
  • DE-U-85 33 092 it is known from DE-U-85 33 092 to automatically form a roll from a web of flexible material in a machine.
  • the object on which the invention is based is to provide a device which automatically forms a roll from a part of a web of flexible material which is fed from a transport device and is cut off at the ends by a cutting device, in particular a job of sectional drawings on paper, and this roll to a magazine.
  • a cassette is arranged in the web transport direction after the cutting device, which consists of a first cassette part fixed to a frame and a second cassette part pivotally held on the frame about an axis, which between a first position in which the two cassette parts enclose a substantially cylindrical interior for the execution of the roller, and a second position is pivotable, in which the interior is open for the release of the roller, that a first cassette roller and a second cassette roller are spaced apart from one another on the frame are rotatably supported, whereby the axis of the first cassette roller corresponds to the axis of the pivotable mounting of the second cassette part, that on the second cassette part a third cassette roller is rotatably held at a distance from the first and second cassette rollers and that the cassette rollers are driven synchronously and with a part of them Extend peripheral surface in the cylindrical interior for the roll formation.
  • a section of a web of flexible material cut off at the ends by a cutting device can be automatically formed into a roll and delivered to a magazine without the need for an operator.
  • sectional drawings, divided into individual jobs are continuously produced on a paper web by means of a computer-controlled drawing device, the individual jobs are also cut off computer-controlled and brought into the form of a roll, the rolls being collected in a magazine.
  • the flexible material is either dimensionally stable in the rolled state, releasably self-adhesive or provided with an adhesive.
  • the cassette rollers each consist of a shaft on which traction sheaves are held in a rotationally fixed manner at a distance and that the second cassette part consists of arcuate brackets which are connected by rods.
  • the invention sits on the shaft of the first cassette roller on the one end of the cassette opposite side of the frame, which is drivingly connected via a toothed belt to a gear wheel on the shaft of the third cassette roller or on the Second cassette roller shaft sits.
  • the gear of the second cassette roller is expediently driven.
  • Such an arrangement requires only a single drive for rotating the first, second and third cassette rollers, since the distance between the first cassette roller and the second cassette roller or between the first cassette roller and the third cassette roller when the second cassette part is pivoted about the axis of the first cassette roller identical axis remain constant.
  • the axes of the cassette rollers are arranged on the corners of an equilateral triangle when the cassette is closed, in order to be able to transmit sufficient frictional force to the web to form a roll.
  • a strapping device which has a roll of a belt and a belt transport device which is rotatably mounted on the frame and which tangents the belt into the cylindrical interior of the Cassette leads to the strapping of the roll. In this way, the rolled sections cut from the web easily maintain their rolled state. The strapping can adhere to itself.
  • the rolls formed can be strapped in a controlled manner, starting from the point in time at which the web is cut off.
  • the fixing member can be a heatable pin for the thermal welding of the strapping and the severing of the strap if the strap is made of plastic.
  • the device as shown in Figures 1 to 6 is arranged after a cutting device 13, of which only the knife is shown.
  • the cutting device 13 is fed a web 26 through a transport device, of which only a pressure roller 14, a transport roller 15 and a guide plate 27 are shown.
  • the device has a cassette which is held on side parts 10 a, 10 b of a frame 10 and consists of a first frame-fixed cassette part 12 and a second cassette part which is formed by arcuate brackets 16 which are connected by rods 17.
  • the second cassette part is held on the side parts 10 a, 10 b of the frame 10 so as to be pivotable about an axis which is located above the fed web 26.
  • the bracket 16 is a extending over about 200 o disc-shaped ring portion.
  • the device also has two cassette rollers mounted on the side parts 10 a, 10 b of the frame 10 and a cassette roller mounted on the end-side bow-shaped brackets of the second cassette part.
  • Each cassette roller consists of a shaft 19, 20 and 21, on which traction sheaves 18 are held in rotation at intervals.
  • the traction sheaves 18 are arranged between the brackets 16 and extend with part of their circumferential surface into a cylindrical interior 11, which is formed by the closed cassette.
  • the axes of the shafts 19, 20 and 21 are arranged at the corners of an equilateral triangle.
  • the axis of the shaft 19 coincides with the axis about which the second cassette part on the side parts 10 a, 10 b of the frame 10 is pivotally held above the track 26.
  • the shafts 19 and 20 extend through corresponding openings in the brackets 16 of the pivotable second cassette part, the shaft 21 extends through corresponding openings in the frame-fixed first cassette part 12.
  • the shafts 19, 20 and 21 are mounted on one side part 10 a of the frame 10 and each have a gear 32, 33 and 34 on their ends protruding from the side part 10 a.
  • the gear 32 seated on the shaft 19 is connected via a toothed belt 22 to the gear 33 seated on the shaft 20.
  • the gear 32 seated on the shaft 19 is connected by a further toothed belt 23 to the gear 34 seated on the shaft 21.
  • the gear 34 seated on the shaft 21 is driven via a toothed belt 24 by a drive gear 36 mounted on the side part 10 a, the drive of which is not shown.
  • the shaft 19 is rotatably mounted on the side part 10 b in a sleeve which extends through the side part 10 b and is fastened to the bracket 16.
  • a gear 25 On the other end of this sleeve sits a gear 25, the axis of which is coaxial with the axis of the shaft 19 in this construction and of a drive gear, not shown, via a toothed belt for opening and closing the cassette, i.e. for pivoting the of the brackets 16 and the rods 17 formed second cassette part between the closed position shown in Figures 3, 4 and 5 with a cylindrical interior 11 and the open position shown in Fig. 6, in which the second cassette part is pivoted upward by about 60 o from the closed position.
  • a strapping device is provided below the cassette, which straps a band 30 from a band reel (not shown) mounted on the frame 10. through a belt transport device 31 and a guide plate 41 tangentially into the cylindrical interior 11 of the cassette for strapping the roller 40.
  • a welding device 28 is arranged on the frame 10 for welding the band to itself.
  • the welding device 28 has a heatable pin 29 which can be displaced by a drive 42 between a rest position outside the cassette (FIG. 4) and a fixing position in the cylindrical interior 11 of the cassette (FIG. 5).
  • a programmable control unit controls in connection with a computer-controlled drawing device in a predetermined cycle the drive of the transport roller 15, the drive of the shafts 19, 20 and 21, the reversible drive of the gear 25, the belt transport device 31, the cutting device 13 and the drive 42 of the Welding device 28.
  • the web 26 provided by this drawing device with a set of sectional drawings runs between the transport roller 15 and the pressure roller 14 and over the guide plate 27 into the cylindrical interior 11 of the cassette.
  • the traction sheaves 18 grasp the web 26 and first guide them tangentially into the cylindrical interior 11 and along the cassette parts delimiting it, forming a roller 40. To prevent a jam in the cylindrical interior 11, the traction sheaves 18 rotate somewhat faster than the transport roller 15.
  • the drive of the transport roller 15 and the drive of the traction sheaves 18 are stopped, the drive of the traction sheaves 18 running slightly.
  • the chasing of the Traction sheaves 18 cause a paper tension, which has an advantageous effect when the sheet is cut off.
  • the cutting device 13 is actuated, which cuts the web 26 at a predetermined point (FIG. 4).
  • the drive of the traction sheaves 18 and at the same time the drive of the belt transport device 31 are switched on.
  • the drive of the gear 25 is actuated, whereby the second cassette part, that is to say the arcuate brackets 16 connected by rods 17, is pivoted upward about the axis of the shaft 19 to such an extent that the strapped roller 40 can fall out of the cassette into a magazine ( Fig. 6). Finally, the second cassette part is pivoted back by the drive of the gear wheel 20 into the closed position in which the cylindrical interior 11 is ready for the formation of the next roller 40.
