Detailed Description
The present invention is a steering lever for film transport, which has a plurality of film support members that form a gas ejection portion that ejects gas toward a film continuous body on a drum-like peripheral surface, a connection member that connects the film support members coaxially with each other, and a fastening member that fastens the connection member to the film support members, wherein specific embodiments of the steering lever for film transport may be arbitrary as long as the steering lever has a structure as follows: the film supporting member has a gas supply through-hole portion which communicates with the gas discharge portion and extends in the axial direction, a fastening insertion hole portion through which the fastening member is inserted and extends in the axial direction, and a screw hole portion which is screwed with the fastening member, and the connecting member has a ventilation through-hole portion which communicates with the gas supply through-hole portion of the film supporting member and extends in the axial direction, a fastening insertion hole portion through which the fastening member is inserted and extends in the axial direction, and a screw hole portion which is screwed with the fastening member, and when a problem occurs in the cylindrical peripheral surface of the film conveying steering lever, only the film supporting member which has a problem can be freely replaced.
For example, the drum-shaped peripheral surface of the film support member may be arcuate, may be formed over the entire periphery of the film support member, or may be formed only in a part of the film support member.
Accordingly, the cross-sectional shape of the film support member may be circular or fan-shaped.
For example, the gas ejection portion of the film support member may be in any form as long as the gas can be supplied to the film continuous body, and specifically, may be a porous material disposed on the film support member or may be a minute hole formed in the cylindrical peripheral surface of the film support member.
For example, the gas ejected from the gas ejection portion of the film support member is preferably air, but may be other gases.
For example, the film support member is preferably a hollow cylindrical body from the viewpoint of weight reduction, but may be a solid cylindrical body.
In this connection, the connecting members are also identical.
For example, the fastening member may be any member as long as the connecting member can be fastened to the film supporting member and can be freely screwed to the screw hole portion of the film supporting member or the screw hole portion of the connecting member.
In particular, if the connection member is a member that can be inserted into the film support member or the connection member from one direction to sequentially fasten the connection member to the film support member, an example is a hexagon socket screw formed of a head portion having a hexagonal hole portion and a screw portion having a smaller diameter than the head portion, but the fastening member may be a member other than the hexagon socket screw.

In addition, the diameter of the head of the short bolt 141 is the same as the diameter of the head of the long bolt 142.
<3 > film supporting Member
Next, the film support member 110 constituting the film conveying turn bar 100 will be described with reference to fig. 3, 4C, and 5A to 5C.
Fig. 5A is a left side view of the film support member shown in fig. 2, fig. 5B is a cross-sectional view VB-VB of fig. 5A, and fig. 5C is a cross-sectional view VC-VC of fig. 5A.
As shown in fig. 3, the film support member 110 is a cylindrical member, and is composed of a cylindrical metal base 111 and a cylindrical porous material 112 provided on the outer periphery of the base 111.
As shown in fig. 5B, concave flange seats 111a are formed on both end surfaces of the base material 111.
Further, a hollow portion 111b extending in the Z direction as an axial direction and penetrating the film support member 110 is formed in the center of the flange seat portion 111a.
The diameter D of the flange seat 111a is substantially equal to the diameter of the connecting member 120.
Further, a through passage for air supply (through passage portion for air supply) 111c that extends in the Z direction (axial direction) and communicates with the porous member 112, a bolt insertion hole (fastening insertion hole portion) 111d that extends in the Z direction and allows the long bolt 142 to be freely inserted, and a screw hole (screw hole portion) 111e that is screwed with the screw portion of the short bolt 141 are formed in the bottom surface of the flange seat portion 111a.
As shown in fig. 5, the air supply through-passage 111c is formed by a through-passage main body 111c1 extending in the Z-direction and penetrating the film support member 110, and a branching hole 111c2 branching laterally from the through-passage main body 111c 1.
The branch hole 111c2 extends in the radial direction, and communicates the through-passage main body 111c1 with the porous material 112.
As shown in fig. 5C, the bolt insertion hole 111d extends in the Z direction to penetrate the film support member 110, and is inserted with a long bolt 142 as a socket head cap bolt.
That is, the bolt insertion hole 111d is formed by a large diameter portion 111d1 having a diameter larger than the outer diameter of the head portion of the long bolt 142 for accommodating the head portion of the long bolt 142, and a small diameter portion 111d2 having a diameter larger than the outer diameter of the screw portion of the long bolt 142 and smaller than the outer diameter of the head portion of the long bolt 142, through which the screw portion of the long bolt 142 is freely inserted.
The center of the large diameter portion 111d1 coincides with the center of the small diameter portion 111d 2.
The center of the gas supply through-passage 111c (through-passage main body 111c 1), the center of the bolt insertion hole 111d, and the center of the screw hole 111e, which are formed as described above, are disposed on the same circumference.
Further, as shown in fig. 5A, bolt insertion holes 111d and screw holes 111e are each arranged at equal intervals.
In the porous material 112, a surface in contact with the base material 111 communicates with the outermost cylindrical peripheral surface 112a.
Thus, the gas supplied from the branch holes 111c2 of the base material 111 to the porous material 112 flows into the surface in contact with the base material 111, and is ejected from the cylindrical peripheral surface 112a.
Therefore, a gas ejection portion that ejects gas toward the film continuous body is formed on the cylindrical peripheral surface 112a of the porous material 112.
The gas supply through-passage 111c may communicate with the gas discharge portion.
<4. Connecting Member >

As shown in fig. 6A, the seal member seat portion 121 is circular in side view, and as shown in fig. 6B, the seal member seat portion 121 is formed on both end surfaces of the connection member 120.
A ventilation through hole (ventilation through hole portion) 121a extending in the Z direction as an axial direction and penetrating the connecting member 120 is formed in the center of the sealing member seat 121.
As shown in fig. 3, the ventilation through hole 121a communicates with the air supply through passage 111c of the film support member 110.
The center of the ventilation through hole 121a coincides with the center of the seal member seat 121.
As shown in fig. 6A, the diameter of the ventilation through hole 121a is smaller than the outer diameter of the seal member seat 121.
Therefore, the seat surface 121b that abuts the O-ring 160 is formed in the seal member seat 121.
As shown in fig. 6B, the bolt insertion hole 122 extends in the Z direction to penetrate the connecting member 120, and a short bolt 141 as a socket head cap bolt is freely inserted therethrough.
That is, the bolt insertion hole 122 is formed by a large diameter portion 122a having a diameter larger than the outer diameter of the head portion of the short bolt 141 for accommodating the head portion of the short bolt 141, and a small diameter portion 122b having a diameter larger than the outer diameter of the screw portion of the short bolt 141 and smaller than the outer diameter of the head portion of the long bolt 142, through which the screw portion of the short bolt 141 is freely inserted.

The closing member 130 is a member disposed at an end opening portion of the film support member 110, and is composed of a left closing member 130L serving as a left end portion of the film transport steering lever 100 and a right closing member 130R serving as a right end portion of the film transport steering lever 100.
The left closing member 130L and the right closing member 130R are each formed of a disk-shaped flange portion 131 and a grip portion 132 protruding in the Z direction from the vicinity of the center of the flange portion 131.
As shown in fig. 4A to 4C, the diameter of the flange portion 131 is substantially equal to the outer diameter of the flange seat portion 111a of the film support member 110.
Further, the flange portion 131 is formed with a bolt insertion hole (bolt insertion hole portion) 131a extending in the axial direction (Z direction) of the film conveyance turning lever 100 through which the short bolt 141 is freely inserted, an air supply port mounting hole (air supply port mounting hole portion) 131b which is freely screwed with the air supply port 170, and a vent hole (vent hole portion) 131c which communicates with the hollow portion 111b of the film support member 110.
Further, in the left side closing member 130L and the right side closing member 130R, the positions of the bolt insertion holes 131a are different.
The bolt insertion hole 131a penetrates the flange portion 131 in the axial direction, and is free to be inserted with a short bolt 141 as a socket head cap bolt.
That is, the bolt insertion hole 131a is formed by a large diameter portion having a diameter larger than the outer diameter of the head portion of the short bolt 141 for accommodating the head portion of the short bolt 141 and a small diameter portion having a diameter larger than the outer diameter of the screw portion of the short bolt 141 and smaller than the outer diameter of the head portion of the short bolt 141 for allowing the screw portion of the short bolt 141 to be freely inserted therethrough.
The center of the large diameter portion coincides with the center of the small diameter portion.
The air supply port mounting hole 131b penetrates the flange portion 131 in the axial direction, is formed with an internal thread screwed with the air supply port 170, and is formed with a slope (taper) toward the film support member 110 side.
Accordingly, the diameter of the air supply port mounting hole 131b decreases toward the film support member 110 side.
Further, the center of the air supply port mounting hole 131b and the center of the bolt insertion hole 131a are arranged on the same circumference.
The vent hole portion 131c is provided near the grip portion 132, penetrating the flange portion 131 in the axial direction.
The center of the vent hole 131c is aligned with the center O of the flange 131 (i.e., the axial center of the film transfer lever 100) and the center of the air supply port mounting hole 131 b.
As shown in fig. 4A, 4B, etc., the diameter of the grip portion 132 is smaller than the diameter of the flange portion 131.
<6.O Ring >
The thickness of the O-ring 160 is larger than the depth of the concave seal member seat 121 provided in the connecting member 120.
Thus, when the film support member 110 and the connection member 120 are fastened by the fastening bolts 140, the O-ring 160 is pressed, and the gap between the air supply through-passage 111c of the film support member 110 and the ventilation through-hole 121a of the connection member 120 can be sealed.
<7 > assembling of steering rod for film transportation
Next, a method of assembling the steering lever 100 for film feeding will be described with reference to fig. 3.
As shown in fig. 3, when the film transport steering rod 100 is assembled, the coupling member 120 is inserted into the concave flange seat portion 111a provided in the film support member 110 in a state in which the O-ring 160 is placed on the sealing member seat portion 121 of the coupling member 120.
Then, in a state where the ventilation through hole 121a of the connection member 120 and the through passage body 111c1 of the air supply through passage 111c of the film support member 110 are opposed, the gasket 150 and the short bolt 141 are inserted into the bolt insertion hole 122 of the connection member 120, and the short bolt 141 and the screw hole 111e of the film support member 110 are screwed, thereby fastening the film support member 110 and the connection member 120.
At this time, the membrane support member 110 and the connection member 120 are fastened by the short bolts 141, whereby the connection member 120 is pressed against the membrane support member 110 by the heads of the short bolts 141 and the spacers 150 to generate an axial force (axial force), and the O-ring 160 is pressed by the axial force to suppress leakage of air from the gap between the membrane support member 110 and the connection member 120.
The coupling member 120 is inserted into a concave flange seat portion 111a provided in the film support member 110 in a state where the O-ring 160 is placed on the sealing member seat portion 121 on the exposed side of the coupling member 120.
Then, in a state where the through-passage body 111c1 of the through-passage 111c for air supply of the film support member 110 and the through-passage 121a for ventilation of the connection member 120 are opposed, the spacer 150 and the long bolt 142 are inserted into the bolt insertion hole 111d of the film support member 110, and the long bolt 142 and the screw hole 123 of the connection member 120 are screwed, thereby fastening the film support member 110 and the connection member 120.
At this time, the thin film support member 110 and the connection member 120 are fastened by the long bolts 142, whereby the thin film support member 110 is pressed against the connection member 120 by the heads of the long bolts 142 and the spacers 150 to generate an axial force, and the O-ring 160 is pressed by the axial force to suppress leakage of air from the gap between the thin film support member 110 and the connection member 120.
In the above-described procedure, the film support member 110 and the connection member 120 are fastened to a predetermined length by the fastening bolts 140, and the end opening portion of the film support member 110 is closed by the closing member 130.
At this time, in a state where the gas supply port mounting hole 131b of the closing member 130 and the through passage body 111c1 of the gas supply through passage 111c of the film support member 110 are opposed, the gasket 150 and the short bolt 141 are inserted into the bolt insertion hole 131a of the closing member 130, and the short bolt 141 and the screw hole 111e of the film support member 110 are screwed, thereby fastening the film support member 110 and the closing member 130.
<8 > Effect exerted by the steering column 100 for film transportation
According to the film conveyance turning bar 100 of the present embodiment described above, by providing the plurality of film support members 110 in which the gas ejection portion that ejects the gas toward the film continuous body W is formed in the cylindrical peripheral surface 112a, the connection members 120 that connect the film support members 110 coaxially with each other, and the fastening bolts 140 that fasten the connection members 120 to the film support members 110, the conveyance direction can be changed by supporting the film continuous body W in a noncontact suspended state by the gas, the length of the film conveyance turning bar 100 can be easily adjusted by merely increasing or decreasing the number of the film support members 110 and the connection members 120, and the ejection amount of the gas can be easily adjusted in the longitudinal direction of the film conveyance turning bar 100.
Further, in the film support member 110, a through passage 111c for air supply, which is a through passage portion for air supply, which is an axial direction extending to communicate with the air discharge portion, a bolt insertion hole 111d, which is a through passage portion for fastening, which is an axial direction extending to allow the fastening bolt 140 to be freely inserted therethrough, and a screw hole 111e, which is a screw hole portion to be screwed with the fastening bolt 140, are formed, and a through passage 121a, which is an air passage portion extending to communicate with the through passage portion 111c for air supply of the film support member 110, which is an air passage portion extending to extend to allow the fastening bolt 140 to be freely inserted therethrough, and a screw hole 123, which is a screw hole portion to be screwed with the fastening bolt 140, are formed in the connection member 120, whereby the fastening bolt 140 is inserted from the bolt insertion hole 111d of the film support member 110 and the screw hole 123 of the connection member 120 are screwed therewith, whereby the film support member 110 and the connection member 120 are freely fastened, and the fastening bolt 140 is inserted from the insertion hole 122 of the connection member 120 and the screw hole 122 is inserted from the screw hole 120 and the screw hole 122 of the connection member 120 is formed in the connection member 120, and the connection member 110 is detached from the connection member 120, and the film support member is easily broken, even if the film support member is detached from the lower support member or the film support member is damaged.
Further, by inserting the connection member 120 into the film support member 110 in the Z direction, the surface area of the film support member 110 that supplies air to the surface of the film continuous body W increases as compared with the film transport steering lever 100 in which the film support member 110 is inserted into the connection member 120 that does not support the film continuous body W, and therefore the film continuous body W can be supported in a non-contact suspended state more uniformly.
Further, the O-ring 160 as a sealing member is disposed between the film support member 110 and the connection member 120, and thus, when the film support member 110 and the connection member 120 are fastened by the fastening bolt 140, the gap between the gas supply through-passage 111c of the film support member 110 and the ventilation through-hole 121a of the connection member 120 is sealed by the O-ring 160, and thus, leakage of gas from the gap between the gas supply through-passage 111c of the film support member 110 and the ventilation through-hole 121a of the connection member 120 can be prevented.
Further, by inserting the fastening bolts 140 through the film support member 110 or the connection member 120 from one end side in the axial direction to fasten the film support member 110 and the connection member 120, the assembly process of the film transport steering lever 100 is simplified as compared with the case where the film transport steering lever 100 is assembled by inserting the fastening bolts 140 through the film support member 110 or the connection member 120 from both sides in the axial direction, and therefore, the film transport steering lever 100 can be assembled or disassembled efficiently.
Further, the concave seal member seat 121 is formed on the end surface of the connection member 120, and the concave seal member seat 121 is a concave seal member seat having an outer diameter larger than the diameter of the ventilation through hole 121a, and the depth of the seal member seat 121 is smaller than the thickness of the O-ring 160, whereby the film support member 110 and the connection member 120 are fastened only by the fastening bolt 140 in a state in which the seal member is placed on the seal member seat 121, and therefore, the gap between the air supply through hole 111c of the film support member 110 and the ventilation through hole 121a of the connection member 120 can be sealed, and therefore, the gap between the air supply through hole 111c of the film support member 110 and the ventilation through hole 121a of the connection member 120 can be easily sealed.
Further, since the bolt insertion holes 111d and the screw holes 111e of the film support member 110 are respectively arranged at equal intervals on the end surface of the film support member 110 and the bolt insertion holes 122 and the screw holes 123 of the connection member 120 are respectively arranged at equal intervals on the end surface of the connection member 120, the fastening force of the fastening bolt 140 when the connection member 120 and the film support member 110 are fastened by the fastening bolt 140 acts substantially uniformly in the circumferential direction, and therefore, not only leakage of gas from the contact surface between the connection member 120 and the film support member 110 can be prevented more reliably, but also deformation of the film conveyance steering rod 100 due to the fastening force of the fastening bolt 140 can be prevented from being generated, and the straightness of the film conveyance steering rod 100 can be improved to convey the film continuous body W more stably.
Further, the bolt insertion hole 111d of the film support member 110 is opposed to the screw hole 123 of the connection member 120, and the bolt insertion hole 122 of the connection member 120 is opposed to the screw hole 111e of the film support member 110, whereby the film transport steering lever 100 can be formed by preparing only one kind of film support member 110 and one kind of connection member 120 each.
< modification >
The thin film transfer steering lever 100 according to an embodiment of the present invention has been described above, but the thin film transfer steering lever according to the present invention is not limited to the thin film transfer steering lever 100 according to the above-described embodiment.
For example, the amounts of gas to be discharged from the film support members may be all the same or may be different for adjusting the amounts of gas to be discharged in the longitudinal direction.
For example, in the present embodiment, the resin is impregnated into the porous material 112, but the resin may not be impregnated into the porous material.
In order to prevent self-excited vibration, the surface of the porous material may be blocked.
For example, the resin may be impregnated into the cylindrical peripheral surface 112a of the porous material 112 in order to prevent dust from flying from the surface.
Further, it is preferable to perform a pore sealing treatment on both side surfaces of the porous member 112 to prevent the escape of gas.
For example, in the present embodiment, the screw hole 123 of the connection member 120 has a bottom, but may penetrate the connection member 120.
For example, in the present embodiment, the O-ring 160 is disposed in the seal member seat 121 of the connection member 120, but a seal member seat for disposing the O-ring 160 may be provided on the film support member 110 side.
Even when the concave seal member seat portion is provided on the film support member 110 side, the diameter of the seal member seat portion is larger than the diameter of the air supply through passage 111c of the film support member 110.
For example, in the present embodiment, both the short bolt 141 and the long bolt 142 are used as the fastening bolt 140, but one type of bolt may be used by adjusting the length of the connecting member in the left-right direction, the position of the large diameter portion, the thickness of the flange portion of the closing member, and the like.
