4 Claims. (Cl. 242-56) The present invention relates to winding method and apparatus for winding web, particularly to provide an improved winding method and apparatus for winding web having constant length.

In the conventional method of winding web, such as fabric, paper, synthetic film, etc., the fully wound web is taken off from a supporting member and an empty mandrel is inserted into the supporting member. After winding web having a desired length the supplied web is cut and the forward edge portion of the supplied web is instantly fixed on an empty mandrel by means of using bonding agent or a suitable catch member, and these operations have usually been performed manually. However, these manual operations have prevented an increase in efficiency of winding web and have been considered troublesome, because they require stopping the winding operation while they are performed.

The principal object Iof the present inventionis to provide a winding method and apparatus for winding a constant length of web around succeeding mandrels continuously, without any manual operation and stopping of the winding operation.

The other obj-ect of the present invention is to provide winding apparatus for winding web having a constant :length around succeeding mandrels, comprising an automatic cutting means for the supplied web when the length of wound web is as desired, an automatic attaching means for attaching the forward edge portion of the supplied web to an empty mandrel, an automatic changing means for changing a fully wound mandrel for a succeeding empty mandrel.

According to the present invention, all operations, such as, the operation of cutting the supplied web when the length of wound web around the mandrel is as desired, the operation of fixing the forward end portion of the supplied web, and the operation of changing from a fully wound mandrel to a succeeding empty mandrel, are performed automatically without any stopping of feeding and winding web around a mandrel, whereby the so-called machine-efficiency can be increased, and moreover, winding speed can be increased. By attaching the forward end portion of the supplied web onto the empty mandrel automatically by means of applying fixing means according to the invention, uniform effect of attaching also can be provided, whereby any -occurrence of crease on the wound web can be provided.

An embodiment of winding apparatus according to the present invention is shown in FIGS. 1, 2, 3, 4, 5, 6 and 7. A feeding web 1 is passing upon an empty mandrel M1 and winding around a mandrel M2. The mandrels M1 and M2 are rotatably supported by a pair of supporting arms 2, respectively. A fixing means and a cutting means are disposed above the winding means as shown in FIG. 1. A traverse member 3 slidably engages with the traverse guide 4 which is rigidly supported by frame F. A pair of shafts S and 6 are disposed at the lower extended portion 7 of the traverse member 3. A pinion 9 and toothed wheel 10 are secured to the shaft 5, and a toothed wheel 12 and cutting wheel 11 are secured to the shaft 6 respectively as shown in FIGS. 2 and 3. The toothed wheel 10 meshes with the toothed wheel 12, and the pinion 9 meshes with a rack 13 which is disposed under the traverse guide 4 as one body. The traverse member 3 is connected with chain 14 at its upper portion. 'Ihe chain 14 traverses according to the actuating motion of actuating member (not shown) when the length of wound web around the mandrel becomes desired one, therefore, the traverse member 3 traverses along the traverse guide rod 4. By this traverse motion of the traverse member 3, the pinion 9 is rotated by gearing with the rack 13, the cutting wheel 11 is rotated by rotation of the shaft 6 on which toothed wheel 12 is secured so as to mesh with the toothed wheel 10 which is secured on the shaft 5. As mentioned above, during the transverse shifting motion of the traverse member 3, the cutting wheel 12 is cutting the supplied web by its rotation, and after the respective transverse shifting and cutting motion of the traverse member 3 and the cutting wheel 12, the traverse member 3 returns to its original position according to return motion of the chain 14. A guide plate 15 is disposed at the end of the elongated portion of the traverse member 3 at a right angle to the extended portion of the traverse member 3. The guide plate 15 works as so-called chopping board when the cutting roll 11 works to cut the supplied web 1. In FIGS. 1, 4, -5, 6 and 7 a punching tack holder 16 is secured to a shaft 17, and punching portion 18 is disposed at the forward end portion of the tack holder 16 so as to face to the empty mandrel M1. Tack assembly 19 has a U section with sharp edges and is inserted into the tack holder 16 so as to be able to be slid along a guide bar 20 by pushing member 21 which is actuated by a spring 22, when one tack of the tack assembly 19 is pushed out of the tack holder 16. A plunger holder 23 is secured to a supporting member 24 at the corresponding portion upon the punching portion 18. A plunger 2S is disposed vertically in the plunger holder 23, and the bottom end of the lower elongated portion 26 of the plunger 2S approaches the punching portion 18, and a spring 27 for return motion of the plunger 25 to upward direction is disposed inside the plunger holder 23 as shown in FIG. 1. A set screw 28 works to set the supporting member 24 to the punching tack holder 16. A lever 29 is pivoted to a shaft 17 and one end of the lever 29 forms an impact head 30 for striking head 31 of the plunger 25 and the other end is articulated to a piston rod 33 of fluid pressure cylinder 32. Both end portions of the fluid pressure cylinder 32 are connected with a transfer valve 34 which transfers the connection of fluid conduit with the other end portions of the fluid cylinder 34 by an action of suitable actuating member, such as magnetic clutch, when the winding length of web around the mandrel becomes desired length.

As shown in FIGS. 4 and 5, a fulcrum portion of the lever 29 is secured to the shaft 17 by key, and an end portion of the tack holder 16 is connected by pin 35 to fulcrum cylindrical portion of the lever 29, and a groove 36 extending 0 angle around the axis of fulcrum portion of the holder 16 is disposed at the corresponding position of pin 35 as shown in the drawings. A control roll 37 is disposed at almost middle portion of the lower extended portion 7 of the traverse member 3.

By the above-mentioned punching tack members, when the length of wound web around the mandrel M2 becomes desired length, `a suitable detecting member (not shown) detects the wound length and actuates the transfer valve 34 so as to pull the piston 33 upward direction, then the lever 29 rotates in a clockwise direction, however, the control roll 37 prevents downward movement of the impact head 30 past the control roll 30. After transverse movement of the traverse member 3, that is, after the impact head 30 leaves the roll 37, the piston 33 further moves in an upward direction by the pulling action of the uid cylinder 32 and the impact head 30 is pushed downward, while the tack holder 16 is also rotated in a clockwise direction around the pivot shaft 17. When the bottom portion of the tack holder 16 contacts the empty mandrel M1, through the supplied web, the holder stops its rotational movement, however, the impact head 30 of the lever 29 still rotates in a clockwise direction, because of the existence of the groove 36 which permits excess angular movement around the pivot shaft 17. Therefore, the impact head 30 strikes the head 31 of the plunger 25 so as as to strike and push out the end tack of the tack assembly 19 from the tack holder 16, and the tack is pushed into the mandrel M1. According to the width of supplied web, plural tack holders can be arranged along the supporting shaft 38 so as to insert punching tacks into the empty mandrel M1 at transversely displaced positions along the shaft 38. By the abovementioned punching tack operation, the forward end portion of supplied web can be rigidly attached to the empty mandrel M1, while the above-mentioned cutting roll 11 Vis operating.

winding efficiency can be improved. It is one of thel functional features of the winding means of the invention, which is clearly shown according to the following description. In FIG. 8, -a central shaft 39 is supported by a pair of frames 40, a pair of supporting arms 41 are supported symmetrically by the central shaft 39. Supporting arms 41 are provided with supporting

portions

42, 43 and 44, 45 respectively, at both end portions of the respective arms 41 symmetrical to the central shaft 39.

Rotatable shafts

46 and 47 are supporting by the supporting

portions

42, 44 and 43, 45 respectively. Mandrels M1, M2 are supported by the

shafts

46, 47 so as to rotate together with the respective shaft.

Sprocket wheels

48 and 49 are secured to the

shafts

46, 47 respectively and a sprocket wheel 50 is loosely secured to the shaft 39. The sprocket wheel 50 is driven by a main sprocket wheel (not shown) and the

sprocket wheels

48 and 49 are driven by the sprocket wheel 50 through chaindrive means 51 and 52, respectively, as shown in the drawing of FIG. 8. After winding the forward end portion of the supplied web after aforesaid punching operation and after winding length of supplied web around the mandrel M1, the pair of supporting arms 41 are subjected to rotate 180 by suitable turning mechanism, such as turret mechanism as shown in FIG. 9. In FIG. 9 a turret plate 53 is rotatably secured to the central shaft 39 and the driving

shafts

46 and 47 are supported at the symmetrical position of the turret plate 53 to the central shaft 39. The turret plate 53 is provided with worm wheel 54 as shown in the drawing and the worm wheel 54 meshes with worm 55 which is driven by the driving motor 56 through ideal gearing 57. When the actuating means actuates the driving motor 56, the turret plate turns 53 180, according to the rotation of the driving motor 56.

After the turning motion, the position of the mandrels M1 and M2 are reversely changed, and the supplied web 1 is wound around the mandrel M1, while the mandrel M2 works as guide roller.

When the length of winding web around the mandrel M1 becomes of desired length, a driving shaft 57 is driven by an actuating member (not shown) and rotated to clockwise direction as shown in the drawing of FIG. 8. A sprocket wheel 58 is rigidly secured to the shaft 60 and an endless chain driving means 14 passing guide sprocket wheels 59 disposed on the frame are driven by the sprocket wheel 58 so as to rotate the direction of arrows 62 in the drawing. As described above, the chain 14 is secured to the top portion of the traverse member 3 so as to drive along the traverse guide 4. By this transverse movement of the traverse member 3, the cutter roll cuts 11 the supplied web along the traverse guide 4 as described above. After starting this cutting operation, above-mentioned punching tack operation is provided so as to Iix the forward end portion of the supplied web on the empty mandrel by tack, and after this punching operation and its return operation, the driving shaft 60 turns to the opposite direction so as to return the traverse member 3 to its original position. And after the length of wound web becomes some length, the position of mandrels are changed reversely as mentioned above, and when the length of wound web around the mandrel becomes to desired one, the cutting operation of web is actuated by suitable actuating means (not shown), and the abovementioned Successive operations are repeated.

In the above-mentioned operation, the timing of starting each operation should be designed according to machine speed.

As described above, all operations are performed automatically, the winding efficiency and quality of winding can -be improved remarkably according to the method of and apparatus winding web of the present invention.
