Description of the invention [Technical field to which the invention belongs] The present invention relates to a stretcher for stretching a sheet-like object such as a thermoplastic resin film. [Prior art] A conventional extension device is disclosed in Japanese Patent Application Laid-Open No. 1-2 2 7 1 3 9 and Japanese Patent Application Laid-Open No. 2-95 8 25. It is known to use a chain provided at the entrance / exit side of the film. The wheel and the intermediate driving device disposed in the heat treatment section after the extension process are used to drive the design of the link device. As disclosed in Japanese Unexamined Patent Publication No. 4-1 4 1 409, it is known that the press-in driving device that drives the continuous link with the press-in force is installed in the heat treatment section after the intermediate driving device and the MD shrinking device, and from the entrance The side drive sprocket to the intermediate drive device and the press-in drive device to the exit side drive sprocket are divided into two sections, and each continuous link device is driven so that the link device and the guide rail are not excessively damaged and are not damaged. It will increase the sliding resistance of the link device, and prevent timing deviation and pulsation of the link device. However, even with the latter's conventional technology, it is still believed that the increase in sliding resistance will gradually occur in the timing deviation of the link device, or in the case of extended repeated actions, due to the connection part of the equal length link. Due to the wear and tear caused by mechanical displacement, deviation occurs. Due to the deviation of this link device, the simultaneous failure of the continuous link devices at both ends of the film causes the performance of the stretched film (product film) to decrease, which in turn leads to lower productivity. In addition, the pulsation of the connecting rod device and the damage of the guide rail are to the extent that it can be judged visually -4- (2) (2) 200410815, or the performance of the product film is significantly reduced, and the replacement period of the consumable parts is uncertain. Or, in order to avoid the need for frequent inspections, even if inspections are carried out, the maintainability such as corresponding to the occurrence of sudden abnormalities has not been considered.

Formulas] The following will describe the embodiments of the sheet-like material drawing machine according to the present invention with reference to Figs. 1 and 2. In addition, this embodiment and other embodiments described later are described by way of example as a simultaneous biaxial stretching machine, but as shown in FIG. 6 described later, the same applies to a tenter-type horizontal stretching machine. Fig. 1 is a plan view of a simultaneous biaxial extension machine, and Fig. 2 is a cross-sectional view of a specific equal-length link 32 of Fig. 1. The structure and operation are described below. The continuous link device 3 (a part of the connecting rod is omitted in the figure) is provided with a plurality of continuous link devices 3 (a part of the link is omitted in the figure) provided on both sides of the sheet 1 to hold the end of the sheet 1, etc. The long link device 31 is driven by an inlet sprocket 4 provided on the entrance side of the sheet, and the sheet-side guide portion 5, the intermediate guide portion 6, and the reverse-sheet side of the guide rail in the traveling direction are enlargedly arranged at the ends. The guide portion 7 guides, and gradually expands the clamping distance, and simultaneously extends the sheet 1 in both the vertical and horizontal directions. The sheet 1 is released from the clamping portion 21 of the clamping device 2 and is set in the The sheet sprocket 8 is driven by the exit sprocket 8 on the exit side and returns to the entry sprocket 4. The guide portions 5 to 7 constituting the guide rail are a pair of combined guide grooves. The guide grooves formed on the sheet-side guide portion 5 and the intermediate guide portion 6 that approach the sheet-like object 1 are held by the bearing roller 91. The link shaft 13 (FIG. 2) that connects the holding device 2 holding the sheet 1 is guided through the bearing roller 92 through a guide groove formed in the opposite sheet-side guide 7 and the intermediate guide 6 from the other side. The link shaft 14 (see FIG. 2) without the holding device 2 is held. The link shafts 1 3, 14 are connected by a link plate 15. The equal-length link device 32 ((5) (5) 20044i5i5 is described below as the specific link device 32) provided at a specific position of the continuous link device 3) The anti-sheet-side link shaft 14 is provided with, for example, a reflection plate 1 〇1, and the specific link device 3 is sensed at a position where the reflection plate 1 〇1 and the sensor 10 are opposed to each other while the continuous link device 3 is rotating. 2, the sensor signal will be sent to the control device 1 1 °. Also, from the viewpoint of the real-time correction of the synchronization of the continuous link device 3 from the setting position of the sensor 10, the link device is prone to abnormality. It is preferable that the rear end downstream of the largest bending portion is ideally. It is preferable that the driving forces of the inlet sprocket 4 and the outlet sprocket 8 cancel each other at the rear end downstream of the neutral point. As the sensor 10, a non-contact type photo-sensor, a proximity sensor, etc. can be used. For example, the sensing form of the photo-sensor can be a retro-reflective type, a diffuse reflection type, and the like. In addition, in a situation where the non-contact sensor is difficult to use (high temperature, the sensor part is polluted), as shown in FIG. 3, 'for example, the link shaft 14 on the reverse sheet side is provided with a sensor with a roller. The arm 16 serves as the specific link device 32. As a result, when the sensing arm 16 moves to the setting portion of the limiter 17 of the sensing means, the mechanical limiter 17 is turned on and off, and performs the same operation as the non-contact sensor. The above-mentioned sensing operation is performed by using the specific link device 32 provided in each of the continuous link devices 3 located at both ends of the sheet 1. The control device 11 is constantly monitoring the two continuous link devices 3. When the time difference between the sensing signals of the specific link device 32 and the time difference is greater than or equal to the initial setting, the control device 11 determines that the operation of the continuous link device 3 at both ends of the sheet 1 is asynchronous and controls Drive system (rotation of sprocket at entrance and exit). At this time, the control of the drive system, one continuous link device 3 will normally operate, and the inverter 12 is used to control the other continuous link -8- (6) 200410815 The driving speed of the lever device 3 can also make Both ends are continuous. The movement of the link device 3 is synchronized, but the drive speed of the continuous link device 3 at both ends can also be controlled by using the inverter 12 at the initial setting of the driving speed of the control device 11. On the other hand, in the case where the driving of the sprocket wheels 4 and 8 of the unilateral continuous link device 3 is a single motor that is linked by a reducer or the like, as long as the motor is made, the sprocket wheel 4 is driven by a separate motor. The devices of 8 and 8 can also control all the motors, but it is better to control the outlet sprocket 8 from the main point of the present invention in which the deviation of the extension is determined as soon as possible and the synchronization of the continuous link device 3 is corrected. Furthermore, the reflecting plate 101 provided with the anti-sheet-side link shaft provided on the specific link device 32 need not be limited to one specific link device 32, and a plurality of specific links arranged at a predetermined interval or a predetermined number are arranged consecutively. Set 3 2 is provided with a reflecting plate 101, and the control device 11 can also be used to monitor the synchronization of the plurality of specific link devices 32. For example, determine the synchronization of the specific link device 32 2 with respect to both ends of the sheet 1 and determine the synchronization of the specific link device 32 of the complex array, and determine the ratio of the number of determinations, only in the case of non-synchronization. Controlling the drive train also prevents frequent control. Alternatively, the determination results of the plurality of specific link devices 32 of the constituent elements of one continuous linking device 3 may be used. The determination results of the plurality of specific link devices 32 of the constituent elements of the other continuous linking device 3 may be used. The control device 11 performs a comparison to control the overall synchronization with respect to the continuous link device 3 as a whole. Next, the gripping device 2 is shown in detail in FIG. 4. Clamping device: 2 operating systems with control difference of 14 to install a non-standard rod and equipment. -9- (7) (7) 200410815 Yes: extension of the chain plate 1 5 (main body) 1 5 1 , And a support arm 1 5 1 which is integrally mounted on the extension part (body part) 1 5 2, and a control lever 20 1 which is pivotally pivotally supported on the support arm 1 5 2 and a support lever which is rotatably supported on the control lever 2 0 1 The upper clamp 202 at the lower end and the lower clamp 203 fixed to the extension portion (body portion) 151 make the control lever 20 1 rotate counterclockwise by the spring force of the spring 205, thereby constituting The upper holder 202 which is rotatably supported is lowered, and the ends of the sheet 1 are clamped (clamped) between the lower holders 203. The upper and lower clamps 202 and 203 are shown in detail in FIG. 5. Fig. 5 (a) is a cross-sectional view, and Fig. 5 (b) is a contact surface between the lower clamp and the upper clamp. In the cross-sections of the contact portions of the upper and lower clamps 202 and 203, a horizontal plane 203 1 is formed in the sheet-side region, and two inclined surface portions 203 2a and 2032b are formed downward in the anti-sheet-side region. In addition, FIG. 5 (b) shows the case where the two inclined surfaces 203 2a and 2032b are formed in a three-day moon shape for easy clamping when the lever 201 is rotated counterclockwise, but the shape is not limited to this shape. . In short, since it is difficult to release the sheet from the upper and lower clamps, it is sufficient to form the first inclined surface portion 203 2b in the area in the final movement direction of the control lever 201. The first inclined surface portion 2032b can also form a center line in the direction of movement of the lever of the upper and lower clamps symmetrically as shown in FIG. 5 (b). However, the thickness of the sheet-like object 1 varies from object to object, ranging from tens of μm to several mm. For example, when the upper and lower clamping members 202 and 203 of the clamping device 2 are not provided with a sheet, so that the control lever 20 1 is expected to increase the thickness of the sheet and hold the sheet at the position of the reverse sheet when the sheet is increased. In the state, the relative area of the upper clamping member 202 and the lower clamping member 203 is reduced, and the sheet -10- (8) (8) 200410815 may fall off from the clamping device. Even if the sheet does not fall off, it can be understood from the formula (1) shown below that if the angle 4 between the center line and the vertical line of the lever 201 of the sheet holding position shown in FIG. 4 increases, the sheet is clamped. The force Pc will be reduced. Except when the predetermined clamping force cannot be obtained, the self-tightening effect of the non-moving direction of the control lever will be reduced due to the reduction of the relative area.

Further, when the holding device 2 moves between the preheating section and the extended section, as shown in FIG. 6, the sheet force acts on the upper and lower holding members 202 and 203 ° of the holding device 2, as shown in FIG. 5. , Forming a first inclined surface portion 2032b (holding) in the area in the direction of the end of the control lever, and clamping the end of the sheet 1 with the first inclined surface 2032b, as a result, the sheet clamping force in the direction of the end of the control lever can be enhanced Originally, when the clamping device 2 was moving from the preheating section to the extended section, even when the thickness of the sheet 1 was slightly changed, the self-tightening effect was maintained. This could prevent the sheet 1 from falling out of the clamping device 2. The effects of forming other inclined portions have the following advantages. Generally, the sheet-like object 1 is an indented connecting rod φ body 1 whose end of the sheet-like object 1 protrudes from the holder by several millimeters, but the above-mentioned end portion is suspended by heating and self-weight at the extension portion. Medical [This, a clamp with a vertical edge, the sheet may hook to the edge part, and it may be difficult to release the sheet (depending on the physical properties of the sheet). However, the angle of the lower 'edge portion of the second inclined surface portion 203 2a having a slope on the lower side is an obtuse angle, which can suppress the hooking as described above. Dan, in this embodiment, the shape of the contact surface of the upper and lower clamping members 202 and 203 is represented by a circle.

And the use of the control device 11 often monitors the abnormality, so that the damage to the continuous link device 3 (especially the non-consumable part) will be minimized, and the correct replacement period of the consumable parts can be expected. Sustainability, such as responding to sudden occurrence of abnormalities, is also improved. A slanted surface in the direction of the end of the control lever is provided on the clamping surface of the sheet to obtain multi-directional tensile resistance, and the left and right synchronization of the continuous link device 3 can be reliably clamped even if there is a slight deviation. Hold a thin sheet. However, the thickness of the sheet is different, and the clamping force can be changed to withstand the tensile force in multiple directions. Next, a simultaneous biaxial stretching machine according to another embodiment of the present invention will be described with reference to FIG. In this figure, the same symbols as in FIG. 1 denote the same components, and the description is omitted. The difference between this figure and the first figure is that a section 18 for storing the sheet 1 is provided after the extension of the sheet 1 is completed, and a sensor is provided downstream of the rear end of the contraction section 18 The sensor -12- (10) (10) 200410815 19 of the specific link device 32 is similar in operation and effect to the embodiment in FIG. 1. Furthermore, in the simultaneous biaxial extension machine of this embodiment, as shown in the aforementioned first figure, a sensor 10 for detecting the specific link device 32 is added downstream of the rear end of the maximum bending portion in the extension section. The synchronization of the continuous link device 3 located at both ends of the sheet 1 can be corrected in real time. Next, a simultaneous biaxial stretching machine according to another embodiment of the present invention will be described with reference to FIG. Fig. 8 is a plan view showing an equal-length link device of a simultaneous biaxial extension machine, and in this figure, the same reference numerals as in Fig. 1 indicate the same components, and description thereof is omitted. The difference between this figure and the first figure is that an intermediate drive device 20 is provided downstream of the rear end of the maximum bending portion of the extension section between the inlet sprocket 4 and the outlet sprocket 8. The operation and effect of the sensor 10 that senses the specific link device 32 downstream from the rear end of the bent portion are the same as those of the embodiment shown in FIG. 1. A special effect of this embodiment is that while extending the life of the link device by providing the intermediate drive device 20, the positioning accuracy of the intermediate drive device 20 and the equal-length link device 31 is improved, and the specific link device 32 is improved.

Moreover, the guide portion fixing plate 135 is provided with a plurality of guide portion fixing grooves, and the swing angle ec may be changed by the number of steps. -14- (12) (12) 200410815 In this way, within the limits of the equal-length link mechanism 3 1 and 3 2, the clamping device 2 is swingably connected in a horizontal direction with a predetermined radius, thereby achieving It can suppress the deterioration of the thin sheet due to the increase and decrease of the clamping distance, and prevent the thin sheet from breaking and thick spots. The holding device 2 is connected to the equal-length link mechanism 3 1 and 32 with a connection point (connection portion) 1 30 as a fulcrum, and is swingably connected in a horizontal direction with a predetermined radius and a swing width of 0c, thereby making the control lever 1 3 4 Go to closed direction And between the lower clamping member 203 and the upper clamping member 202, an elastic force is generated to clamp and clamp the end of the sheet 1 to hang on the control lever 1 3 4 and the support wrist 133 Or the spring 205 is formed between the extension arm portion (main body portion) 1 32. In this way, the spring 205 is suspended between the control lever 134 and the support arm 133 or the extension arm portion 132, as shown in FIG. 12 The curved portion 14 at the entrance of the extension section and the curved portion at the exit of the extension section are not affected by the swinging movement of the clamping device 2 for the equal-length link mechanisms 3 1 and 32. At this time, the spring 205 is pulled by The spring is extended, but either the compression spring or the torsion spring can be used to change the mounting position. According to the present invention, even if the sliding resistance is increased, the friction of the isometric link connecting portion is abnormal, etc., it can still be corrected immediately.
