Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a guide jig for transporting a strip-shaped film material such as an IC lead frame, and a transport device using the same.
[0002]
[Prior art]
In general, in a process in which a film material is processed, there is a portion that performs conveyance close to a straight line after the film material is unwound and wound. This is, for example, a portion where application or pasting is performed on one or both sides of the film material and drying or heat treatment is performed. In this case, in the straight conveyance without a guide, if the processing space is long, the film material is likely to sag, flutter, or twist.
[0003]
Therefore, conventionally, a method of transporting both sides of the film material by placing it in a U-shaped guide or guide rail and a method using a guide roller with a hook are generally used. In this case, the guide itself is a film. Since it is held to resist the meandering force of the material, the thin and weak film material is deformed and plastically deformed on the side end surface of the film material and its surroundings each time the meandering occurs. It is easy to cause damage such as being hardened or being hardened while being bent near the center of the film material.
[0004]
In addition, in the case of a method that prevents the film material from sagging by using a levitating device using air or magnetism, the above-mentioned damage is unlikely to occur, but the processing work on the film material is limited, and the structure and control method of the device are complicated There is a problem that the cost of the apparatus increases.
[0005]
Also, in the case of a conveyance method in which both side edges of the film material are nipped by chain conveyance, the elongation of the chain changes depending on the tension and the degree of wear. There is a problem that it also takes.
[0006]
[Problems to be solved by the invention]
The present invention has been made in view of the problems of the prior art as described above, and the object of the present invention is not to damage the side edge of the film material to be transported or the periphery thereof, and the trajectory. An object of the present invention is to provide a film material conveying apparatus that can ensure a certain range and perform stable conveyance.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a film material conveyance guide jig according to the present invention includes a frame which is to be surrounded and fixedly arranged on a film conveyance path so that a film material to be conveyed can pass therethrough, and the frame includes the frame. A pair of guides mounted so as to be movable in the width direction of the film material and supporting each side surface and upper and lower surfaces of the both side edges of the film material; and a pair of guides horizontally mounted between the pair of guides. And a pair of guides and the shaft provided to the shaft when the film material meanders. The film material is configured to follow and prevent deformation of both side edges of the film material, and to restore the film material to a normal traveling path.
[0008]
Further, the film material conveyance guide jig of the present invention includes a pair of guides having U-shaped cuts that guide and support the side surfaces and the upper and lower surfaces of both side edges of the belt-shaped film material to be conveyed, A roller that is sandwiched between washers by a washer between shafts and rotatably mounted so as to make rolling contact with the lower surface of the film material, and a lower end of the pair of guides are supported at a predetermined interval. A guide base plate provided below the shaft, and a frame to be fixedly disposed on the film transport path surrounding the assembly composed of the pair of guides and the guide base plate so that the film material can pass therethrough. Each upper end is pivotally attached to a spaced top of the frame by a shaft, and each lower end is pivotally attached to each end of the guide base plate by a shaft and a washer. When the film material meanders, the pair of guides and the shaft follow and move to prevent deformation of both side edges of the film material, and the film material can be restored to a normal traveling path. I am doing so.
[0009]
In order to achieve the above object, the film material conveying apparatus according to the present invention includes at least one film material on a linear conveying track formed between the film material unwinding device and the winding device. A conveyance guide jig is arranged.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described based on illustrated examples. 1 is a front view of an embodiment of a film material conveyance guide jig according to the present invention, FIG. 2 is a right side view of FIG. 1, and FIG. 3 is a schematic configuration diagram of an embodiment of a film material conveyance device according to the present invention. It is.
[0011]
In the figure, 1 is a belt-shaped film material to be conveyed, 2 is a pair of guides having U-shaped cuts for guiding and supporting each side surface and upper and lower surfaces of both side edges of the film material 1, and 3 is a pair of guides 2 , 2 is a roller which is sandwiched between washers 4 and 4 and is rotatably mounted so as to be in rolling contact with the lower surface of the film material 1. And a guide base plate 7 for supporting the film material 1 so as to allow the film material 1 to pass therethrough and a frame to be fixedly disposed on the film transport path surrounding the assembly composed of the pair of guides 2 and 2 and the guide base plate 6. This is a shaft for pivotally attaching the other end of each of the arms 9 and 9 whose one end is pivotally attached to each end of the guide base plate 8 by the shaft 10 and the washer 11 to the spaced top of the frame 7, respectively. These are the fills according to the present invention. Constitute a timber conveyance guide jig 12.
[0012]
In FIG. 3, 13 is a film material unwinding device, 14 is a film material winder disposed at a predetermined distance from the unwinding device 13, and 15 and 16 are the film material unwinding device 13 and the unwinding device. It is a processing apparatus including a plurality of film material conveyance guide jigs 12 arranged on a linear conveyance track of the film material 1 formed between the take-up machine 14.
[0013]
Since the embodiment of the present invention is configured as described above, when the film material temporarily meanders during the conveyance of the film material 1, the guide 2 on the side meandered by the side edge of the film material 1 is the side (film In this case, the guide 2 receives the force through the arm 9 that rotates about the shaft 8 and the guide base plate 6 that moves by the rotation of the arm 9. Therefore, the side edge portion of the film material 1 is prevented from being deformed by the U-shaped cut of the guide 2 and the film material 1 is prevented from being bent. Thus, when the temporary meandering is taken, the assembly including the guide 2, the guide base plate 6 and the arm 9 returns to the lowest position (normal state) due to gravity, so that the trajectory of the film material 1 is moderately normal. It can be restored to the orbit.
[0014]
Further, by arranging a plurality of film material transport guide jigs 12 side by side on the linear trajectory of the film material 1 from unwinding to winding, as shown in FIG. Since the film can be transported with little drooping and the drag generated between the guides 2 and the meandering film material is low as apparent from the above description, the linear transport entrance and the transport exit are usually used in the processing step. Since the trajectory holding effect due to the tension set between them can be kept low, it is possible to carry the sheet while avoiding the influence of deformation damage of the film material 1 due to meandering with a lower tension.
[0015]
【The invention's effect】
As described above, according to the present invention, even if there is meandering during conveyance, damage to the film material due to the meandering can be avoided, and a film material conveyance guide jig capable of realizing stable running of the film material and the use thereof are provided. It is possible to provide a film material transport device.
