Description

[Detailed Description of the Invention] The present invention relates to a continuous feeding device for sheet-like elongated materials such as films.

BACKGROUND OF THE INVENTION Films are sometimes continuously supplied to both sides of a long sheet and pasted together, and packaging departments are also required to continuously supply long sheets such as films in a predetermined direction.

Figure 1 shows the case where films d and d' are pasted on both sides of a pre-foamed sheet b continuously extruded from an extruder a via shaping rolls c and c.
Film laminated sheet sent to the next foaming process
Two movable bases e and e' are installed below b' to continuously supply the lower film d', and the upper film d is also supplied to one side of the extruder a. A supply base (not shown) is installed, and film rolls f and f' made of film d' wound around a core material such as a paper tube are loaded on these bases e and e' in a freely unwound manner. When the film roll f on one base is completely consumed, the supply of film d' is temporarily stopped, and while the film d' is being supplied from the accumulator g, a new film roll on the other base is added.
By manually connecting film f' with film d' and restarting the supply, film d' is continuously supplied.

However, in this case, since two film supply bases are required, there are problems in that the installation and production space for the bases becomes large, and when connecting the films, it is difficult to use the bases. It has poor workability when moving, centering when installing in a fixed position, and when connecting the film.
Since it requires at least two workers, there were also problems with rationalization measures.

The present invention has been made to solve the above problems, and its configuration will be explained below with reference to illustrated embodiments.

a are pivotally connected to each other by pins 16, and bearings 15b, 15b having approximately V-shaped sides are located at the inner ends of the vertical plates 8', 8' at the tips of these bearing arms 15a, 15a. are provided, and the shaft 13 of the transferred long material roll 9 is pivotally supported by these bearings 15b, 15b.

Further, an operating rod 16a is fixed to one of the bearing arms 15a, 15a.
At the tip of 6a is the piston rod 1 of the cylinder 17.
8 is pivotally connected, and as the piston rod 18 expands and contracts, the bearing arms 15a, 15a can be tilted as shown by the two-dot chain line in the figure, and the bearings 15b, 15b in the tilted state are free-wound. A roll take-out mechanism, that is, a guide passage 19', 1 for taking out the core material 11 and shaft 13 of the long material roll 9.
9″ is the side plate 1a of the device main body 1 and the movable base 2,
It is divided into 1a, 2a, and 2a and is tilted.

Furthermore, a connection/disconnection mechanism 19 for connecting and disconnecting the sheet-like elongated object 12 and a clamping mechanism 20 for holding the elongated object 12 are arranged in the apparatus main body 1.

As shown in FIG. 2, the connection/disconnection mechanism 19 includes a cylinder 21, a piston rod 22, a rotating arm 23 with a heat sealer 23a at one end, and a presser frame 24 fixed to a fixing member 24a.

Therefore, in order to use the device configured as described above, remove the connecting plate 3 that connects the device main body 1 and the movable base 2, move the movable base 2 to the long object roll mounting position, and then The moving base 2 is moved by a shaft 13 that penetrates and fixes the length roll 9 to its core material 11.
After being rotatably supported on the first bearing part 10 of the movable base 2, the movable base 2 is returned to its original position, and the connecting plate 3 is hung to connect and fix the movable base 2 to the main body 1 of the apparatus.

The sheet-like elongated object 12, which is unwound from the elongated object roll 9, is passed over the upper side of the feed roller 29 and the lower side of the pressing roller 28, and is supplied to a supply destination (not shown).

As a result of this supply, when the remaining amount of the long object on the long object roll 9 decreases and the roll diameter becomes less than a predetermined diameter, a detector (not shown) (for example, a photoelectric switch) detects this and issues a notification with a buzzer or the like. With this, the long object roll 9 is replaced with the second bearing part 15 of the apparatus main body 1, and the movable base 2 is moved to the long object roll mounting position as described above, and a new roll 9 is installed. After installing it, return it to its original position and prepare for the next roll.

When the roll 9 on the apparatus main body 1 side approaches the end, this is notified as described above, and the clamping mechanism 20
