Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to films, for example, an outer cover of a greenhouse for greenhouse and horticulture, and a vinyl film for keeping heat inside which is stretched inside the house (hereinafter referred to as a film). ) Is wound into a roll. A device for unwinding a roll wound in the form of a roll, or dispersing the peeling powder on the film surface when unrolling the roll and bonding the sides of the film to each other, and the excess powder after spreading And a device for folding the unraveled film.

(Prior Art) Conventionally, since powder was sprayed directly in the air to spray the powder on the surface of the film in order to prevent adhesion between the films, surplus powder was dispersed in the air.

Also, at the time of or after the unrolling of the raw film, the processing method of the processed film was performed manually or with a simple folding device, so the work was troublesome and there were many problems such as many troubles. There were many and processing work was done without being solved.

(Problems to be Solved by the Invention) In the conventional technique of dusting (spraying) powder on an unenclosed film, the dusted powder is part of the powder adhering to the film surface and most of the powder is scattered into the atmosphere. However, dusting efficiency is low, dusting costs are high, and various problems have arisen in hygiene, not to mention various management problems of mechanical devices and electric appliances.

Further, when the roll-shaped raw material is unraveled, the raw material often shifts laterally or falls off from the raw material mounting table. The switching of the web was also discontinuous.

When the ultrathin films are unfolded and folded, the film is caught in the gap between the drive roller and the end of the butterfly of the folding device, so that the film cannot slide. In addition, the film does not flow smoothly on the butterfly running surface, so that there is a problem that the folded state is poor.

(Means for Solving the Problems) A plurality of raw sheet mounting tables are provided in parallel in a breaking apparatus for rewinding and unwinding a roll-shaped raw sheet, and a raw sheet for preventing lateral displacement and falling on the raw sheet mounting table. A stabilizer was provided.

In addition, a powder dusting device (dusting device) is provided for dusting the surface of the film after unraveling, and the dusting device is covered with a frame so that surplus powder remaining after dusting does not fly into the atmosphere, and dusting is performed in the frame. The surplus powder was set to a weak negative pressure inside the frame to prevent scattering outside the frame, and a recovery port and a suction device were provided at the bottom of the frame to recover the powder outside the frame. In addition, a stirrer for stirring the sprayed powder in the frame was provided to enhance the dusting effect.

Since the film flows smoothly through the folding device that folds the film sent from the dusting device, the film does not enter the gap between the roller and the butterfly with the drive roller shaft and the swinging rotation shaft of the butterfly being the same axis. Obstacles were placed in the gaps as shown. Also, a means for preventing the film from sticking to the butterfly by forming the sliding surface of the butterfly film as an airtight flat surface or forming a plurality of protrusions on the sliding surface in the same direction as the film sliding is provided. Was.

(Operation) After the roll is unwound by unwinding the roll by mounting it on the roll mounting table of the device that breaks the roll of raw material, the film is sent to the dusting device, and the powder is dusted on the film in the dusting device. I do. The powder sprinkled in the frame is cut off by a curtain or brush attached around the frame and is not scattered outside the frame, and the surplus powder is settled in the frame and collected through an appropriate collection port, or a suction fan. And send it out of the frame.

After the powder is attached to the film surface by the dusting device, the raw material is pulled out of the dusting device and sent to the folding device. The film falls smoothly on the butterfly and is folded and placed on the folding table.

(Embodiment) An original film processing apparatus for an original film will be described with reference to FIG.

Alternatively, the film is cut through a film cutting device (I) provided in the concave groove.

It is also possible to freely release the film directly from the drive roller (N) without providing a butterfly and cutting device, and the film can be drawn out freely by changing the mounting position of the rollers (O) and (N). , The position of the dusting device (J) is also the raw material (A) and the roller (O)
It is needless to say that the apparatus can be mounted on any position of the film surface, the back surface on the release side before the roller (O) and the drive roller (N).

The welding portion of the film continuous welding apparatus is usually provided between the roller (O) and the driving roller (N).

(Embodiment 1) The dusting apparatus will be described with reference to FIG. 2. The film (G) released from the raw material moves in the direction of the arrow (14),
While penetrating the gap (15) between the lower frame and the upper frame via the roller (O), the front surface (16) and the rear surface (17) of the film (G)
A powder for release (13) for preventing the film from sticking is attached to the drive roller (N) provided on a frame for preventing the powder from scattering in the dusting device (J).
It becomes open. Although the front and back surfaces of the film differ depending on the type of the film, any film is possible in the present invention.

The dust on the back surface of the film (17) is placed at a predetermined position in the lower frame, for example, near the bottom of the upper portion of the inclined lower frame, and a spout of powder having an appropriate diameter directs the mouth in a substantially film direction at a predetermined interval. Powder transport ejection pipe provided across the frame [hereinafter referred to as ejection pipe]
It is arranged in (11). One end of the ejection pipe is communicated with a discharge port of an air mixing powder production blower and is installed. The powder (1) ejected with air from the ejection port (12) of the ejection pipe (11)
3) is part of the film surface (1) in the dusting device (J).
Most of them adhere to (7), but float in the frame, and most of them settle down and accumulate below the frame.

One or more recovery ports (18) are provided at the bottom or an appropriate lower side of the frame for collecting excess powder deposited on the bottom of the frame of the dusting device (J). An appropriate collecting tank, for example, a box or a bag is provided in the collecting port (18), and the powder accumulated in the frame is taken out from the collecting port (18) and processed.

Also, an appropriate suction device provided outside the collection port (18) provided at an appropriate position in the frame of the dusting device (J), for example, the suction side of an electric fan is communicated with the collection port (18), and the blowout of the fan is performed. The excess suspended powder in the dusting device (J) is collected via a dust collector communicating with the side, for example, a cyclone.

When the demolition work is stopped, the powder processing work is facilitated by inserting the accumulated powder into the recovery port (18).

One or a plurality of suction pipes (19) having an appropriate cross-sectional shape, for example, a round shape or a square shape, in the entire length or in the required portion of the lower portion in the frame of the dusting device (J), one end of which is substantially closed, and The outer end of the outer frame provided with the end protruding outside the frame, and one or more suction ports of an appropriate diameter arranged in the suction pipe (19) substantially upward (20) or in the appropriate direction (21). , A dust collecting device that communicates with the suction side of the electric fan, and a device that sucks and collects the unneeded powder and accumulated powder in the frame via a cyclone.

One or a plurality of suction ports are provided at appropriate positions of the frame of the dusting device (J) for preventing the scattering of powder, and air in the frame is appropriately supplied through a suction device communicating with the outside of the suction port, for example, a low-pressure electric fan. When the volume is continuously suctioned and discharged, the inside of the frame becomes an appropriate negative pressure. However, the suction / discharge amount is increased or decreased according to the amount of powder (substantially ejected air amount) injected at the time of dusting into the frame. When the inside of the frame becomes a negative pressure, the above-mentioned various treatments are carried out in the entire amount frame without releasing the suspended powder outside the frame.

There is a problem that the air-mixed powder injected into the frame for preventing the scattering of the powder is thick near the outlet of the injection port provided in the jet pipe, and thinly near the middle thereof on the film surface.

In order to adhere this uniformly, a floating powder agitator, for example, one or more small fans are arranged in the frame, and when the floating powder agitator is operated, the floating powder in the frame is agitated and becomes uniform, and the film surface becomes uniform. Adheres evenly to

A supporting rod (23) having a desired strength and a cross-section is provided at a predetermined position on the underframe main body at an appropriate position outside the frame for preventing powder scattering of the dusting device (J), and the supporting rod is provided. A frame for preventing powder scattering is fixed directly to the tip of (23) or through a suitable support, and the frame is connected to the shaft (22) and the support rod (23).
It is possible to open the frame to prevent the scattering of powder by rotating it through, and attach the film drawn from the raw material to the dusting device, and when processing excess powder in the frame, cleaning, inspection, etc. It is intended to make work easier.

Since the inside of the frame of the dusting device (J) for preventing the scattering of the powder is pressurized due to the air injected from the injection port of the ejection pipe, the powder is scattered to the outside even from a small gap. In order to prevent this, the distance between the film surface and the frame is made small, and a curtain (8) of an appropriate width or an appropriate hardness, density and width are provided at a necessary portion (6) at the end of the frame. Is appropriately mounted, for example, by a pinching screw via a belt-shaped holding plate (5). By mounting in this manner, the air-mixed powder (13) comes out of the film while being in contact with the film surface, so that it adheres well to the film surface and scattering can be minimized.

In addition, one or a plurality of intake ports are provided at appropriate positions on the frame, and a forced suction device capable of adjusting the amount of intake air from the intake port, for example, connected to a suction side of a blower, and the air pressure in the frame is set to an appropriate negative pressure, For example, if the negative pressure is set so that the powder does not fly out of the frame, the scattering of the powder to the outside can be completely prevented.

(Embodiment 2) The folding device will be described with reference to FIGS. 1 and 3. A driving roller (N) for unwinding and drawing out the film of the raw material (A) is based on an appropriate driving device (P). It is fixed to a rotating shaft (25) supported by a suitable bearing and rotates.

The butterfly for folding the finished film is swingably supported on a shaft (25) via a rotating wheel (34) provided at one end of a support bone (33) disposed at a plurality of appropriate positions of the butterfly,
The tip of the butterfly is moved in the direction of arrow (26) by a suitable reciprocating drive (Q). A film sliding on the upper surface of the butterfly is folded in an accordion-like manner in proportion to the period of the swinging motion at the open end of the butterfly.

A drive roller (N) for pulling out the film from the raw material and sending it out to the folding device is rotatably mounted on a plurality of bearings (35) fixed at positions in the width direction of the main body frame. To rotate at reduced speed. An unrolled film (G) is placed on the upper surface of the driving roller, and a single pressing roller (3 cm in width, 10 cm in diameter, for example) having an appropriate width such that the film (G) is pressed onto the driving roller surface. 36) is rotatably supported by a support rod (37). One end of the support rod (37) is rotatably supported at a predetermined position on the main body frame, and when necessary, for example, at the time of releasing work, an arrow (3)
The film is pressed against the drive roller surface by rotating the pressure roller (36) in the direction 8), and the film is fed out in synchronization with the rotation of the drive roller (N).

However, when the surface of the drive roller is finished by ordinary paint coating, the frictional resistance between the roller surface and the film is small, and the number of pressure rollers to be installed or the amount of pressure must be increased. Therefore, almost innumerable small protrusions are formed on the surface of the drive roller to eliminate slip between the roller surface and the film, thereby making it possible to smoothly feed the film.

A rotatable boss (34) is inserted into the shaft (25) of the drive roller (N) between the roller ends, and the end of a support rod (33) is fixed to the boss (34). The rear side of the butterfly is detachably attached to one end of 33), so that the butterfly can swing freely. Suitable position of the butterfly,
For example, by attaching an appropriate rod (39) and a reciprocating motion driving device (Q) substantially behind the central portion, the butterfly makes a rocking motion coaxially with the axis (25) of the driving roller (N).

When the film is disengaged from the raw material and slides on the butterfly of the oscillating film folding device, the film running surface of the butterfly has a structure with an air escape space, for example, a lattice or mesh groove. If it is installed, the film that slides on the butterfly will be pressed against the butterfly surface by the air pressure generated on the surface of the butterfly when the butterfly swings, and it will be difficult to slide, so the plate with no air escape place on the butterfly film sliding surface, Alternatively, when the air layer is constituted by an airtight plane having a small air escape space, the air layer is confined between the sliding surface and the film surface, and the friction between the film sliding surface of the butterfly and the film surface is substantially zero. When the film is pushed up, the two layers do not contact each other because the air layer is present, and when the film is pulled down, the air layer expands. Since pressure attracts the film becomes low, during oscillating movement maintains a substantially constant distance between the always-film surface and the butterfly surface film is gliding.

In the same direction as the film running on the film running surface of the butterfly, one or a plurality of appropriate protrusions, for example, a ceiling width of 5 m
The above air layer effect could be improved by mounting a rod having a section of m and a height of 10 mm.

Surface of drive roller (N) for feeding film (28)
A constant gap (29) is formed between the film roller shaft (25) and the surface of the upper part (27) of the butterfly, which is coaxial with the film roller shaft (25);
The film (G) fits well in the gap (29) and is clogged. This phenomenon is caused by the fact that the film rotates and the film stops moving on the running surface of the butterfly film while the butterfly is rising, so that the film loses its place to go. The gap (29) is closed to prevent the film from getting stuck.

A plurality of hooks (32) are attached to a part of the main body frame on the material roll side of the drive roller (N) at intervals of, for example, about 60 cm, and a suitable string (31), for example, a frictional resistance is attached to the hooks (32). One end of a string having a suitable repulsive force is bound, and the other end (30) is attached to the upper part of the butterfly by wrapping around a driving roller (N), or an appropriate cross section is used instead of the string. For example 1.5mm
A steel wire or 1 × 10 mm strip is formed in a substantially U-shape, and one end is attached to the hook (32), and the other end is attached above the butterfly, or a suitable chain is used instead of the string. Can also be used.

A similar effect was obtained by attaching one end of an elastic rubber material or a suitable spring material to the hook (32), and attaching the intermediate member with an appropriate tension.

In FIG. 4, a concave groove or an opening (40), for example, in the longitudinal direction of the butterfly (in the width direction or in the lateral direction of the film), is provided at an appropriate position above the butterfly, for example, at a position about 10 cm below the upper end. A groove of about 2 to 3 cm is provided, and when the film is unwound to a predetermined length and finished, the film is cut along the concave groove (40) with a cutting knife or scissors.

A bottom portion (41) of the concave groove (40) is a hollow elongated structure (41), and a rail (42) for running a truck is laid inside the hollow elongated structure (41), The wheels supported by the trolley (43) roll on the rails, causing the trolley (43)
In the longitudinal direction of the butterfly. A pulley (44) for a belt U-turn is pivotally supported at one end of the rail (42), and a belt drive pulley (45) is mounted on the other end side via a drive reduction motor (46) so as to be rotatable left and right. Have been. A belt, for example, a timing belt (47) is stretched annularly between the pulleys (44) and (45), and a bogie (43) is attached to the belt. The bogie (43) moving in the hollow long structure (41) can rotate the motor (46) in the direction of the arrow (51) in the direction of the arrow (51) via the pulley (45) and the belt (47) and can travel a predetermined distance. I do.

A cutting blade stand (49) protruding from the groove (40) is provided on the film side of the cart (43), and the cutting blade (49) is provided with a cutting blade (5).
0) is attached to the film side with an appropriate inclination.

When the film has been unraveled for a predetermined length, or when the end of the film is trimmed, the motor (46) is driven to move the carriage provided with the cutting blade (50) in the direction of the arrow (52). Then, the cutting blade (50) starts cutting the film from the right end, and reaches the left end of the rail to complete the cutting. Dolly (43)
Returns to the right and stops at the origin when the film is cut.

For the unraveling device without the folding device, a narrow film sliding table is installed next to the final film feed roller (butterfly position) at an appropriate angle, for example, inclined at 30 to 45 degrees from vertical. By providing the concave groove or a cutting device that travels in the concave groove at the position, the film can be cut into a right-angled straight line.

(Embodiment 3) Referring to FIGS. 1 and 5, a raw film breaking apparatus will be described. The width of a film (A) is usually, for example, from 2 m to 6 m at intervals of about 20 cm, and the length is 100 to 100 m. The film thickness is 700 m, and the thickness of the film is 0.05, 0.075, 0.1, 0.125, 0.15, 0.2,..., And there are many types such as quality, material, characteristics, etc. depending on the manufacturer.

In the film breaking operation, a film according to the customer's order is selected, the required length of the film is broken through a raw material breaking device and sold, and the remaining film is removed. For this reason, no problem occurs if the film is of the same kind, but since one or a plurality of material rewinding material mounting tables (Y) are arranged in series in the width direction of the material film, this is one device. If the film is a little different, the work of reloading the film on the original mounting table is troublesome, and the unraveling work is discontinuous.
Therefore, for example, as shown in the drawing, a plurality of the source mounting tables are arranged in parallel on the front surface of a driving roller (N) for drawing out the film from the source, and the plurality of source mounting tables are set in advance. The original film of the type that is most likely to be unwound is placed on each of them, and the desired film is selected when necessary and unwound continuously.

In FIG. 5, the raw sheet mounting table (Y) is composed of a plurality of parallel rollers (57) supported on an appropriate long frame (62). In order to prevent the three rolls (Y) from unwinding the film in parallel with each other, for example, lower the side close to the support roller (O). , The distant side is set high. The sheets (A1), (A2) and (A3) placed on the sheet carrier have different film widths from (61), (60) and (59), and the sheet is used as the sheet carrier. The film is placed irrespective of the placement position, and the film can be taken out more freely than any material. The unraveling work is usually one sheet, and the unraveled film (63) or (64) or (65) is pulled by the drive roller (N) via the roller (O) and sent in the direction of the arrow (55). Be sent out.

Referring to FIGS. 1 and 6, the raw sheet mounting table will be described. The raw sheet placed on the raw sheet mounting table and rotated while being unrolled is moved in the film width direction. , It is placed in an unstable state with no support, such as falling down from the substrate holder. For this reason, when the film is moved in the film width direction, the edges of the finished film are disturbed, and the welding width is not uniform during the film welding operation. In addition, if the sheet falls, it becomes impossible to immediately release the next sheet. Therefore, the sheet mounting table of the present invention is configured by attaching a movement preventing device to the end of the sheet and inserting a core rod into the sheet core.

Two rollers (57) are supported in parallel at the top of a suitable length web frame (62), and a plurality of detachable movable web mounting tables (Y) extend in the width direction of the web. They are arranged in series at appropriate intervals. A web (A) is rotatably mounted in a direction indicated by an arrow (69) on two rollers (B) of the web mounting table (Y), and the web (A) is a roll of a tubular body. Core (6
7) The film is rolled around the circumference. There are various types, such as large-diameter rolled long films (dotted circle 79) and small-diameter rolls. In the unraveling operation, the roll-wound film is pulled out and rewinded sequentially from the outer peripheral edge of the roll-wound film to be unraveled. Eventually, the roll core (67) will be a lightweight core. The roll core (67) is rotated from the top of the source mounting table to move from the top to the bottom until there is no more source material than when the source material has a large diameter.
At the beginning of the unwinding, when the unrolled material has a large diameter, the weight is heavy, and the unrolled material is stably unrolled on the unrolled material mounting table. This development is large when the degree of adhesion between the films is large. In addition, it moves in the width direction of the raw material in the direction of arrow (80) simultaneously with the rotation.

Therefore, as a means for preventing falling and movement, raw material stabilizers (R) are provided at both left and right ends of the raw material.

The material stabilizer (R) includes a base plate (71) detachably attached to the material mounting base frame (62), and a pair of cross sections for preventing the raw material fixed to the base plate from moving left, right, front and back. A movement prevention tool consisting of a hook-shaped member (72), and a fall prevention insertion core rod (74) attached to the movement prevention tool and inserted into the roll core of the raw material
And a core rod escape prevention plate (77) for preventing the falling core rod (74) from moving in the film width direction.

The base plate (71) is a plate material having a shape to be installed on the upper side of the raw material mounting base frame (62). The film is detachably screwed and fixed at a position where the movement in the width direction of the film can be stopped via the material movement preventing device.

At the right and left appropriate positions on the upper surface of the base plate (62), for example, symmetrically with respect to the width direction of the film, at the front and rear positions of the end of the raw material, the height of the new raw material is substantially the highest. At about position,
With the short width side of the hook-shaped member (72) of the movement prevention device consisting of a pair of hook-shaped members (72) outside, the wide width side (73)
Was provided as a raw material side. The narrow gap (81) between the pair of hook members (72) is slightly smaller than the inner diameter of the core (67), for example, 70 to 80% of the inner diameter, and the lower portions of the pair of hook members are fixed to the base. Since the wide surface side (73) is in contact with the end of the winding core (67), the movement in the film width direction can be prevented by attaching the movement preventing device to both ends of the material.

In the narrow space (81) between the pair of hook-shaped members (72), a core rod (74) having an appropriate length that penetrates the space and allows up and down movement, for example, about 4 to 5 times the inner diameter of the core. ) Is provided with a collar (75) at one end of the core rod, and the other end is inserted into the core (68). The flange (75) is a plate-shaped body, and can freely pass through the wide gap (82) between the pair of left and right flange members (72) in the width direction of the raw fabric. Therefore, the core rod (74) inserted into the core (68) may move in the film width direction and protrude out of the movement preventing tool. In order to prevent this protrusion, insert the retaining (76) inside the pair of hooks of the movement prevention tool from the top of the flange (75) in the direction of the arrow (77) and press the flange to move in the direction of the original fabric. To prevent. The retaining (76) is a plate-like body,
The width can freely enter and exit both hooks of the pair of hook members (72),
In addition, it does not come out after insertion, the length is shorter than the length of the pair of hook-shaped members (72), and an appropriate grip portion is provided.

The above-mentioned material stabilizer (R) is attached to both ends of the material placed on the material placing table, and the core rod (74) is inserted into the core. (76)
Is inserted, the core rod (74) does not come out of the core (68). For this reason, the raw material (A) does not move in the film width direction at the time of unraveling, and even if the unraveling progresses and becomes a small diameter, the core rod (74) itself does not descend and fall out. Is supported by the core rod and does not fall.

(Effects of the Invention) Since the present invention is configured as described above,
The roll-shaped raw material can be released stably on the raw material mounting table,
I can work smoothly with less trouble.

Conventionally, another swing shaft is installed below the drive roller shaft,
Although the folding device was oscillating, the mechanism could be simplified by making the driving roller axis and the oscillating axis the same axis.

By providing the groove or opening on the film sliding surface of the butterfly, the film is cut along the groove, so that the cut edge is not inclined or meandering, and becomes straight at right angles.

When a device for cutting the film is provided on the film running surface of the butterfly or the film of the table, when cutting the film continuously, for example, when cutting a plurality of raw materials of about 500 m into a short length of 20 to 50 m, etc. Immediately after cutting the film in a straight line at right angles, the film can be unraveled.

By installing a plurality of source mounting tables in parallel on the front of the drive roller that pulls out the original film, there is little need to replace the film during unwinding, and the unwinding work can be performed efficiently. It is.
