Other features and advantages of the apparatus for splicing sheet materials according to the invention will be explained in detail below with reference to the accompanying drawings, which illustrate preferred embodiments of the invention.

In FIG. 1, the apparatus for splicing sheet materials of the present invention is generally designated by the reference numeral 10. A device for splicing sheet materials (hereinafter simply referred to as splicing device): a pair of supports 11 arranged at a distance of one river and movable relative to each other;
, 12. The upper surface of the support has coplanar supporting surfaces 13, 14 for supporting the sheet strips to be spliced.
is formed. The opposing front twill parts 15, 16 of the supporting surfaces 13, 14 are brought into close contact with each other by the movement of the support body 12 when the sheet strip pieces are spliced together, so that they form one horizontal plane. are arranged in parallel to form a Clamp devices 17 and 18 for fixing the sheet material to the support surfaces 13 and 14 of the supports 11 and 12 are arranged symmetrically on the supports 11 and 12, respectively, with the front twill part as the center, and 11, 12 (on the side opposite to the front twills 15, 16) include clamp arms 19, 20 pivotally mounted.

The clamp arms 19 and 20 are pivotally attached to the front twill side end portions, and when the end portions are lowered onto the support surfaces 13 and 14, the sheet is placed on the support surfaces. a holding member 21 for fixing the shaped material to the stereotactic layer;
22 is attached. Furthermore, the support surface 13,1
At the bottom of the support near the front edges 15, 16 at 4, stopper sections 23, 24 are pivotally mounted to orientally position the sheet material fed onto the support surface.

The stop members 23, 24 have an L-shaped cross section and extend along the front edges 15, 16. When the stopper members 23, 24 are pivoted by a suitable actuating device (not shown), the claw portions 25, 26 at the tips of the stopper members rise from the front green portions 15, 16 of the support surface and move to their positions. dimensionally designed to form a wall. As shown in FIG. 1, the claw portions 25 and 26 of the stopper members 23 and 24 are arranged so that the sheet-like material placed on the support surfaces 13 and 14 protrudes by a small amount from the front green portion of the support surfaces. Notches 27 and 28 are provided. The support surface 14 of the support body 12 is provided with a groove 29 formed near the front edge portion 16 and along the front green portion.

Although the groove 29 has a trapezoidal cross-sectional shape in the embodiment shown in FIG. 1, it may have any shape as long as it does not allow the attachment described later to come off easily.
Explaining the attachments to be attached to the grooves 29, there are basically two types of attachments to be attached to the grooves 29 formed in the support surface 14 of the device 10. These are appropriately selected depending on the method of joining the sheet materials. That is, in the case of butt joining in which the end surfaces of sheet materials are brought into contact with each other and joined as described above, the first attachment method 30 having a cross-sectional shape as shown in FIG. 2 is used. On the other hand, in the case of lap joining in which the ends of sheet materials are overlapped and joined, a second attachment 31 having a cross-sectional shape as shown in FIG. 3 is used. The first attachment has an external shape that forms the support surface 14 into a completely flat surface when it is attached to the groove 29.

The second attachment 31 also includes a groove 29 formed in the support surface 14, as shown in an enlarged view in FIG.
When the attachment 31 is attached to the support surface 1
4 has an inclined surface 32 that faces upward toward the front twill portion 16 at the attachment 31 portion thereof, and a wall extending a predetermined distance Q from the front green portion and substantially perpendicular to the support surface 14. A vertical surface 33 extends substantially perpendicularly to the support surface 14 from the inclined surface 32 to form the support surface 14 .

When the second attachment 31 is attached to the second attachment 31 and the sheet material is lap-jointed, the groove 29 is used to prevent the joint from catching on the vertical surface of this attachment when feeding the sheet material. Formed on the support surface on the feed side of the strip. Further, the support body 11 has a front green portion 1 of the support surface 13 of the support body 11 as shown in FIG.
It is supported by a rotating mechanism 34 so that the angle with respect to the traveling direction of the sheet-like material No. 5 can be changed. Furthermore, the other support 12 is supported by another rotation mechanism 35, like the support 11, and this rotation mechanism 35 is supported by a slide mechanism 36. As a result, both the supports 11 and 12 can change the angles of their front edges 15 and 16 with respect to the traveling direction of the sheet-like material, and the supports 12 can be moved to the support 11 by the sliding mechanism 36. The object is given the motion of approaching or moving away from it.
Next, the operation of the sheet material splicing apparatus 10 of the present invention will be explained. FIGS. 2a to 2c schematically show the operating sequence of the splicing apparatus 10 when butt-joining sheet-like materials.

According to this, when the present device 10 is used for butt welding, the groove 29 formed in the support surface 14 has a first attachment, that is, a butt weld, which forms the support surface 14 into a completely flat surface as described above. The spacer 30 for use is attached. Then, when the supports 11, 12 are positioned with a larger interval, the stopper members 23, 24 are pivoted, and the claw portions 25, 25 at the tips of the members are pivoted, as shown in FIG. 2a.

, 38 are pressed and fixed. Then, Figure 2b
As shown in FIG. 2, the stopper members 23 and 24 are returned to their original positions, that is, to the bottom surface of the front edge of the support surface. Next, the support body 12 is brought close to the support body 11 by the slide mechanism 36,
This results in support surfaces 13, 14 as shown in FIG. 2c.
The end surfaces of the sheet-like material protruding from the front green part of the sheet are butted against each other and joined. 3a to 3c schematically show the operating sequence of the present splicing apparatus 10 when lap-joining sheet-like materials.

According to this, when the present device 10 is used for lap bonding, the groove 29 formed in the support surface 14 has a second attachment, that is, a lap bonding surfacer having a cross-sectional shape as described above and shown in FIG. 31 is installed. Referring to FIG. 3a, the sheet-like material 39, which has already been spliced into a long strip and is located on the support surface 13, is moved in front of the support 12 by the slide mechanism 36. When the edge 16 hits the front green part 15 of the support 11, it is returned in the direction indicated by the arrow, ie in the opposite direction to the feeding direction.

As a result, the end of the sheet-like material 39 is transferred onto the support surface 14 and the vertical surface 3 of the second attachment 31
3 and stops. Therefore, the sheet material 39
This means that the end has been transferred onto the support surface 14 by a length Q shown in FIG. The clamping device 17 is then actuated to fix this sheet-like material 39 against the support surface 13, as shown in FIG.
9 is dropped.

As a result, the pressing member 21 presses the front green portion 15 of the support body 11.
The sheet-like material 39 is pressed and fixed onto the support surface at. Thereafter, a new sheet strip 40 is fed over the support surface 14 in the direction indicated by the arrow, as shown in FIG. 3b. This sheet strip piece 40 rides on the inclined surface 32 of the negotiation attachment 31 which passes over the second attachment 31 attached to the groove 29 and advances. Then, the end portion of the sheet strip piece 40 comes into contact with the pressing member 21 of the clamp arm 19 and is stopped. As a result,
The end of the new sheet strip 40 that has been fed is above the end of the sheet material 39 that has been lifted by the inclined surface 32 of the attachment 31 and transferred onto the support surface 14, and has a length Q. There will be some overlap. The clamping device 18 is then actuated and the clamp arm 20 is lowered as shown in Figure 3c.

At this time, the holding member 22 attached to the end of the clamp arm 20 is shaped to have a width that fits into the area between the vertical surface 33 of the attachment 31 and the front green part 16. Therefore, the width of the tip of the holding member 22 is the length Q. As a result, the sheet material 3
9 and the end of the sheet strip material piece 40 overlap by a length Q and are joined. As described above, according to the sheet material joining apparatus of the present invention, lap joining and butt joining can be performed with one apparatus.

That is, it is possible to select a joining method for sheet materials very easily by simply replacing the attachment and changing the electrical sequence to change the operating order of each part.
