Therefore, the above device will be specifically explained in accordance with the order of operation.

Reversing arm device (A) and film transfer device (B) (20) in Fig. 3 shows a transport vehicle, in which a pair of left and right pedestals (not shown) that support the roll film from below can move up and down. In addition, the lower surface of the roll film is supported from left and right on the pedestal with the roll film diametrically upright, and the device frame shown in Figure 1 (
21) toward the position of the guide hole (22).

The guide rod (20a) of the carrier (20) is inserted into the guide hole (2).
2) and set in place, the first
In response to the signal from the sensor (23) shown in the figure, the transfer rod (25) of the transfer device (24) shown in Fig. 3 moves forward with the cylinder (26) to the position where it can support the roll film from below, and transfers the film. As the device (24) moves forward, the transport truck (20
) is moved upward, and the roll film is transferred to the transfer rod (25).

The transfer device (24) is attached to the rail (27) of the frame (21).
The cylinder (26) is attached to the guide stand (28) that moves along the
) are directly connected, and a transfer rod (25) is horizontally attached to the guide stand (28) via a support (29), and this transfer rod (25) can hold the lower part of the roll film. There are a pair of left and right holders, and they are inserted between the pair of pedestals on the left and right sides of the transport vehicle, making it easy to transfer the roll film.

The roll film is transferred from the trolley (20) to the transfer rod (25) (
25), the transfer device (24) is retracted by the cylinder (26), and the paper tube at the center of the roll film is supported by the film collection chuck spool (30).

Now, to explain the sensor (23) mentioned above,
The film thickness of the roll film is detected by reflectance, and as shown in Figure 7, there are three positions: transportable set position (b), film remaining amount set position (C), and film edge set position (d).
), in position (b), a film transfer device fixed position stop signal is issued, a new roll film is supplied to the film transfer device, and in position (C), the film suction and conveyance pad, which will be described later, is moved backwards (in the figure). to the left).

Further, in (d), an operation command signal for the reversing arm is issued.

As shown in FIG. 1, the reversing arm (36) includes a pair of right and left collect chuck spools (30) (30a), and is adapted to be reversed in order to switch from an old film to a new film.

Further, the structure of the collect chuck spools (30) (30a) provided in a pair on the left and right sides of the reversing arm (36) is as follows.

That is, as shown in Fig. 11, the center shaft (31)
A slide holder (32) is attached to the tip of the center shaft (31), which is attached to a spring (32) at the base of the center shaft (31).
33), it is constantly moved to the retracted position.

When the slide holder (32) is retracted, the coiled spring plate (35) interposed between the movable end (32a) of the slide holder (32) and the fixed end (32b) of the center shaft (31) (32a) is pressed so that the center swells, and this fixes the paper tube (e).

When the slide holder (32) is pushed out against the spring (33) by the chuck unclamp cylinder (34) (34a) in Fig. 2, which will be described later, the spring plate (35)
is released from the movable end (32a) and fits between the fixed end and the movable end due to the restoring force of the spring plate (35) itself, and the diameter of the collect chuck by the spring plate (35) is reduced.

Therefore, by pushing out the center shaft (31) against the spring (33) with the chuck unclamp cylinder (34) shown in FIG. 2, the slide holder (32) is pushed out, the spool diameter is reduced, and the roll film is It can now be inserted into the paper tube (e) in (f).

The collect chuck spool (30) (30a) is attached to the reversing arm (36), and is provided in pairs on the left and right as described above so that the old roll film and new roll film can be attached. The index motor (
At 36a), invert and fix the new roll film.

The spool (30) has an index 1111 recognition sensor (
110), and the transfer device (24) is located in the cylinder (
Since it is in the retracted position at 26), a new roll film can be inserted into the collect chuck spool (30) as described above.

In addition, the aforementioned chuck unclamp cylinder (34
) (34a) is the left and right spool (30) (30a)
Each vertical frame (2
1a).

Next, as shown in Fig. 1, there is a sensor (37) with a paper tube on the vertical frame (21a), and this
) is detected, and the transfer device (24) is moved back and forth to adjust the front and back positioning of the roll film relative to the spool (30).

This fine adjustment is carried out under the control of a control device.
After fine adjustment, the pusher of the left chuck unclamp cylinder (34) moves back as shown, and the slide holder (32) also moves back and pushes the leaf spring (35), so the spool (30") rolls. Film paper tube (e
) to be fixed.

The above fine adjustments are performed to correct film meandering.

Film feed positioning device (C) Next, when the film end detection sensor located at the same position as the paper tube presence sensor (37) detects the hanging end of the film, the film feed positioning device (C) is activated.

As shown in Fig. 1, the film feed positioning device (C) includes a roller pressing cylinder (38) and an arm (4) that swings through a link (40) with this piston rond (39).
1), the arm (41) has a roller drive motor (42) that drives the feed roller (43).

Therefore, the arm (41) in the cylinder (38) tilts toward the roll film (f) and presses the roller (43) against the roll film (f), and the roller (43) moves the roll film (f) by the drive of the motor. It has a structure that allows it to rotate.

Therefore, when the film tip detection sensor (37) detects the hanging film tip, the roller pressing cylinder (38) is activated to swing its arm (41) and move the roller (43) to the roll film (f). ), the motor (42) operates to rotate the roller (43) and detect the film leading edge detection sensor (37).
) during a predetermined timing from the operation of the roll film (f)
When the roller (43) reaches the fixed position half a turn,
stops rotating, and at this time the roller pressing cylinder (
38), the roller (43) leaves the new roll film (f) and waits for the next operation.

As described above, when the film feed positioning device operates and the leading end of the roll film is set at a fixed position, the next film transport device operates.

Film conveyance device (D) The film conveyance device (D) sucks the leading edge of the film set at a fixed position and conveys the film to the cutter device and taping device. There is a film transporting upper and lower cylinder (45) that moves back and forth by a film transporting cylinder (44) arranged between the cutter position and a film suction transporting pad (46) at the lower end of this film transporting upper and lower cylinder (45). .

This film adsorption/transport pad (46) detects that the old film has reached the remaining film cent position (C) using the sensor (23) described above, moves backward to the position of the new roll film, and is already on standby. Therefore, when the roll film stops rotating in the manner described above, the upper and lower film transport cylinders (45) descend to attract the leading edge of the film.

The film suction conveyance pad (46) is in a lowered state and is attached to the film conveyance cylinder (44) while adsorbing the end of the film.
to move forward (to the right in the figure) and transfer it to the cutter and taping device.

When the leading edge of the film is conveyed to the cutter and taping device, the film suction conveyance pad (46) also serves as a film holding device, so it works with the next film fixing device to effectively cut and tape the film. to be fixed.

When the film is cut and taped, the film suction and conveyance pad (46) is raised by the film conveyance upper and lower cylinders (45) when it is attracted, and then moves backward in response to a signal from the next sensor (23).

Film fixing device (E) As described above, the leading edge of the film is attached to the film fixing device (E).
The sensor (23) of the cutter and taping device will be set at the film edge setting position (E).
d) is detected and activated, and automatic splicing is started.

Therefore, to explain specifically about the film fixing device (E) that fixes the film before the cutter and taping device work, this is a suction hole provided on a surface plate for fixing the film that sucks the film from below. , consists of a film holding and discharging device that presses the film from above, and as shown in Fig. 12, the surface plate is a rear surface plate (48), a front surface plate (49), and a swingable device installed between them. It consists of an intermediate surface plate (50) and is provided below the cutter and taping device.

The base of the intermediate surface plate (50) is pivoted (53) to the rear surface plate (48) as shown in FIGS. It swings so that it does not interfere with the operation of the cutter device.

These surface plates are provided with suction holes and connected to a vacuum generator.

Film presser/discharge device (5) that presses the film from above
4), as shown in Fig. 4 (c) and Fig. 13.14, the cylinder (56) is connected to the frame (100) before and after film ejection.
), which allows the film discharge rotation actuator (55) to be attached to the guide (56c) that moves along the rail (56a).
An arm (55b) that swings about a fulcrum (56b) with this lever (55a) has a film discharge upper and lower cylinder (57), and a spring (57a)
The suction fixing plate (58), which is energized upward, is moved up and down.

And, the suction fixing plate (58) is always attached to the frame (21).
It is located outside and is stopped at an angle of 45° to the film flow direction, and the film ejection rotary actuator (55) is rotated at the same time as the film ejection front and back cylinder (56) is pulled in by the taping device operation signal. It moves perpendicularly to the new leading edge of the film, and by the downward movement of the film ejection upper and lower cylinders (57), the leading edge of the film is simultaneously attracted to the film presser and the film can be moved to the ejecting operation.

Below this film holding/discharging device (54), there is a separating plate (
59) as shown in FIG. 12 to prevent static electricity from being generated due to contact between the new film and the old film.

In this case, the new film is transported by the film transport device (D) described above and set on the film fixing device (E) so that the new film end overlaps the old film end.

When the film is set on the film fixing device (E), the film is sucked from below through the suction holes of each surface plate (48), (50), and (49), and the film holding and discharging device (54) works to suck the film from below. The suction fixing plate (58) also holds the film from above with the film discharge upper and lower cylinders (57).

The aforementioned film adsorption/conveyance pad (46) presses the film from above after the film has been conveyed.

When the film is pressed in the manner described above, the film stop cylinder (60) shown in FIG. 1 operates, and a portion of the stopper descends to hold down the old film.

In this case, the dancer roller (61) is raised to ensure that there is no problem with film feeding.

In any case, the reason why the dancer roller (61) is raised is to provide extra time for automatic splicing using adhesive tape.

Cutter device (F) When the film is pressed, the cutter device f (F) operates next. The cutter device consists of a lower blade (62) shown in Figures 8.12 and 15 formed at the rear end of the front surface plate (49), and an upper blade (63) that swings up and down. .

When the upper blade (63) descends, the intermediate surface plate (50) is swung downward by the cylinder (51) so that the cutter descends without any hindrance.

The drive mechanism for the upper blade (63) is as follows.

That is, as shown in Fig. 8, the upper blade (63) is attached to the frame (10
1), its lower end is pivoted (64), a suspension string (65) is attached to its upper end, the suspension string (65) is suspended via a guide roller (66), and a weight is attached to its lower end. (67), the upper blade (63) is always directed upward and energized.

A roller (7
0) acts to press the upper blade (63) downward.

For this purpose, a piston (71) of a cylinder (72) is pivotally supported (73) at the lower end of the drive arm (69), and when the cylinder (72) operates, the drive arm (69) raises the roller (70). The blade (63) is swung downward against the force of the weight (67).

The cutter device also has a cutter safety stop.

As shown in Figure 9.10, the proximal end of the arm (75) with the safety pin (74) protruding from it is pivotally supported on the support (76), and the piston rond (77) of the cylinder (78) is attached to the arm (75).
It is supported by (79).

Therefore, before the work that does not require the upper blade (63) to descend, the cylinder (78) works to swing the arm (75) forward with its piston rond (77), thereby moving the safety pin (74) of the cutter. The cutter (63) is made to protrude within the range of the downward falling locus to prevent cutter work from being carried out due to the cutter (63) falling unexpectedly.

Since the cutter device (F) is configured as described above, the intermediate surface plate (50) is lowered by its cylinder (51) to open the path of the cutter, and then the cylinder (7)
2) works, the roller (70) of the drive arm (69)
The upper blade (63) is lowered against the force of the weight (67), and the film is cut together with the lower blade (62).

The film is cut at the point where the new film overlaps the old film, and the end of the cut new film is adsorbed by the film holding/discharging device (54), and then the film is cut at the point where the new film overlaps the old film. ) to the front of the device (in the direction perpendicular to the paper), and the film discharge rotation actuator (55) moves the suction fixing plate (58) to 4
It is rotated 5 degrees to release the suction and disposed of in the scrap box (94) shown in FIG.

After discarding the cut end of the film, the suction and fixing plate (58) stops at a fixed position inclined at 45 degrees with respect to the film flow direction, and waits until the next film is spliced.

Taping device (G) Next, the taping device (G) works.

The taping device includes a frame (100) for moving the adhesive tape head (83) back and forth as shown in Figure 4.5.
Taped front and rear cylinders (82) r
There is a "rodless cylinder" and a taped upper and lower cylinder (81) that allows the main body to move up and down.

The main body (83) has an adhesive tape reel (80), and the tape (91) that is drawn out via a guide roller (84) is attracted to a suction pad (85). 85) also has a head body (
A pad up and down cylinder (92) fixed to the pad (83) moves up and down via a piston rod and an arm.

In addition, the main body (83
), there is a tape pasting roller upper and lower cylinder (102) on the plate (104) that moves with the rond (
The arm (105) swings up and down via the arm (90), and its roller (88) moves up and down.

The plate (104) also has an adhesive tape cutter (8
9), which is connected to the sixth tape cutter rotary solenoid (86) via the cutter holder (87).
As shown in the figure, it rotates in the film width direction.

Now, the adhesive tape (91) is drawn out from the reel (80) via the guide roller (84) to the suction pad (85) and is suctioned there. When this is detected, the taping device operates, and the head body (83) is moved to the right end in the film traveling direction by the tape application front and rear cylinders (82), and the head body (83) is lowered by the tape application upper and lower cylinders (81), and then further Pad upper and lower cylinder (92)
The suction pad (85) presses against the edge of the cut film.

Next, tape the front and rear cylinders (82) to the main body (8
3) and the plate (104) move leftward in the figure, the adhesive tape (91) is pulled out from the reel (80) and connects the old film and new film. In this case, so as not to impede the movement of the head,
Adsorption by adsorption bands has been eliminated.

When the end of the film is reached, the suction pad (85) suctions the adhesive tape (91), and the rotary solenoid (86)
), the cutter holder (87) rotates, and the cutter (89) cuts the film. Cutter (89)
Since it uses the cutting edge of a commercially available cutter, it can be changed at any time.

The roller (88) rolls on the tape adhered to the film as the head body (83) and plate (104) move, thereby pressing the tape onto the film. The pressure bonding is performed by swinging the arm (105) with the rod (90) using the tape application roller and upper and lower cylinders (102).

When the above cutter operation is completed, the head main body (83) is lifted by the taped upper and lower cylinders (81) and waits until the next operation.

In this case, the roll (88) is also moved upward by the tape application roller upper and lower cylinders (102).

And the rotary solenoid for the tape cutter (8
In step 6), the cutter is also restored to its original position.

When the tape application is completed as described above, the film transport upper and lower cylinders (45) raise the suction transport pad (46) which has been suctioned, and the suction fixing plate (58) of the film presser/discharge device (54) also moves upward. The film rises, and the suction by the film suction hole is released, the stopper in the film stop cylinder (60) rises, and the dancer roller (61) starts to descend and returns to its home position.

In this way, the paper tube ejection cylinder (47) shown in FIG.
The operation of pushing out the empty paper tube is given from a).

At this time, chuck unclamp right cylinder (34a
), the diameter of the collect chuck is reduced by the operation of The paper tube waste receptacle is a box (9
5). At this time, the cut old film is discharged together with the paper tube.

The reversing arm (36) is rotated by a return signal from the paper tube discharge cylinder (47), and the spool (30a) is stopped at a fixed position corresponding to the film transfer device (24).

At this time, the sensor (23) has already detected the set position where the film can be transported, and the film transfer device is activated by the reversing arm (3).
6), so a new film roll is supplied to the spool (30a) in the manner described above.

Automatic splicing is performed by repeating the above cycle, but the operation of the device is controlled by the control device (shown in Figure 1).
103), and the movements of each device, including the film reversing device, are all driven by air cylinders.

Furthermore, according to the specific taping apparatus described in claim 6, the end of the adhesive tape is reliably pasted to the end of the spliced part of the roll film by the suction pad, and the adhesive tape reel is moved by the movement of the tipping head. The adhesive tape can be automatically pulled out from the tape and adhered to the end of the new roll film and the end of the old roll film by pressing the adhesive tape with a tape application roller.

In addition, the adhesive tape that has been pasted is cut with an adhesive tape cutter, and at the same time as it is cut, the cut end of the adhesive tape is suctioned and fixed to the suction pad, so that when moving on to the next taping operation, the adhesive tape is securely attached to the film splicing area. It has the characteristic of being able to be bonded to the surface of the film, and of being able to perform continuous film splicing.
