Description of the Related Art Conventionally, in a strip-shaped sheet feeding apparatus as described above, there is provided a continuous sheet feeding source for continuously feeding the strip-shaped sheet and a take-up mechanism for picking up the strip-shaped sheet fed from the continuous sheet feeding source. A storage mechanism is provided in the sheet supply path, and dancer rollers are provided in front of and behind the storage mechanism, respectively, and when the belt-shaped sheet is stored and discharged, the drive speed of the lift drive mechanism is controlled to positively move the lift roller at a required lift speed. There is one that can be raised and lowered (for example, Japanese Patent Publication No. 63-432).

引き取り機構が減速を開始する。In this belt-shaped sheet feeding apparatus, the belt-shaped sheet is zigzag-shaped between the stationary roller and the elevating roller of the storage mechanism, and the elevating roller is raised while the take-up mechanism stops the take-up of the belt-shaped sheet to store. The band-shaped sheet is stored in the mechanism. In order to discharge the strip-shaped sheets stored in the storage mechanism, the take-up speed by the take-up mechanism is made higher than the sending speed from the continuous sheet supply source, and the elevating roller is lowered. When the elevating roller descends to the lower limit, the discharge of the strip-shaped sheet is completed. At the same time, a detector such as a limit switch detects the raising / lowering roller, and the raising / lowering drive mechanism stops the raising / lowering drive of the raising / lowering roller according to the detection signal, and the take-up mechanism starts deceleration.

ために貯溜機構の前後のダンサーローラが作動するよう
にしてある。The elevating roller descends at a speed based on the difference between the feeding speed and the take-up speed of the strip-shaped sheet during the discharge of the strip-shaped sheet from the storage mechanism. Then, when the discharge of the strip-shaped sheet is completed, the descending of the strip-shaped sheet is instantaneously stopped. On the other hand, the take-up mechanism, which has started decelerating when the discharge of the strip-shaped sheet is completed, gradually reduces the take-up speed to the same speed as the feeding speed from the continuous sheet supply source. Therefore, when the lowering of the elevating roller is stopped, the take-up speed becomes faster than the feeding speed from the continuous sheet supply source, and unless the speed difference between the two is absorbed, excessive tension is applied to the belt-shaped sheet in the storage mechanism. As a result, the strip-shaped sheet breaks. Therefore, when there is a difference between the delivery speed and the take-up speed, the dancer rollers before and after the storage mechanism are operated to absorb the difference in speed.

じて不良品になったりするという問題を生じる。However, since the dancer roller has a resistance in the ascending / descending direction due to its own inertial force, friction of the guide portion, and the like, a speed that is instantaneously high between the delivery speed and the take-up speed. When there is a difference, it is not possible to perform a light movement to cope with it, and the speed difference cannot be sufficiently absorbed. Therefore, tension fluctuation occurs in the belt-shaped sheet and the belt-shaped sheet runs laterally, and the tension fluctuation adversely affects the tension of the belt-shaped sheet in the processing device on the downstream side. There is a problem in that the product may be defective.

An object of the present invention is to provide a strip-shaped sheet feeding device that can prevent defective products and can feed the strip-shaped sheet to the downstream with a stable tension.

In order to achieve this, an elevating / lowering speed command means for momentarily calculating the target value of the elevating / lowering speed of the elevating / lowering roller based on the difference between the current belt-like sheet feeding speed and the current belt-like sheet take-up speed and outputting it to the elevating / lowering mechanism is provided. Is actively moved up and down at an appropriate drive speed.

零になる。In the storage mechanism, the discharging (storing) speed of the strip-shaped sheet is equal to the difference between the feeding speed and the take-up speed,
The release (reservoir) amount of the strip-shaped sheet can be calculated by integrating the release (reservoir) speed that is momentary.
Further, the amount of elevation of the elevating roller can be obtained from conditions such as the number of elevating rollers of the storage mechanism and the amount of discharge (reservation) of the belt-shaped sheet. Therefore, when either one of the take-up speed and the delivery speed is variable and the other is maintained at a constant speed in the storage mechanism, the ascending / descending amount of the elevating roller during deceleration of the variable take-up (delivery) speed is A simulated calculation can be performed using the set value of the take-up speed (feeding speed) setting means. Therefore, the lift amount of the lift roller from the start of deceleration of the lift speed of the lift roller until the lift speed becomes zero is simulated every moment, and the lift amount by the simulated calculation and the detected current displacement of the lift roller from the reference position. If the two are equal and the deceleration of the take-up (feed-out) speed is started, the ascending / descending speed of the ascending / descending roller becomes zero when the ascending / descending roller returns to the reference position.

永久歪みの発生を防ぐことができる。According to the sheet feeding apparatus of the present invention, the elevating / lowering amount of the elevating roller from the start of the deceleration of the belt-shaped sheet take-up speed to the end of the discharge of the belt-shaped sheet or the deceleration of the feeding speed of the belt-shaped sheet is started. The moving amount of the lifting roller from the start to the end of the storage of the belt-shaped sheet is simulated every moment, and the lifting amount obtained by the simulated calculation is compared with the detected current displacement of the lifting roller, and the take-up speed or feeding By automatically issuing the speed deceleration command, the lifting speed can be set to zero almost at the same time when the lifting roller returns to the reference position. Therefore, unlike the conventional case, the tension of the belt-like sheet does not greatly change due to a rapid change in the ascending / descending speed when the raising / lowering of the raising / lowering roller is stopped, and the belt-like sheet can be supplied with a stable tension.
It is possible to prevent the lateral displacement of the strip-shaped sheet and the occurrence of permanent distortion in the strip-shaped sheet which is easily deformed.

If the magnitude of the acceleration at the time of accelerating or decelerating the take-up speed or the feeding speed is set by the limit value and the rate of change, when the elevator roller starts to move up and down, stops moving up and down, accelerates at the time of lifting up and down, decelerates. Since the ascending / descending speed of the ascending / descending roller can be changed smoothly at the end, the fluctuation in tension of the belt-shaped sheet can be made extremely small. Therefore, the lifting speed of the lifting roller can be increased to shorten the time for discharging or storing the band-shaped sheet. Further, the smoothness of the change in the ascending / descending speed can be easily and variously changed according to the conditions.
