The present invention relates to a method of separating / transporting an apparatus and the apparatus.

[0002]

2. Description of the Related Art As a separation / conveyance apparatus for carrying out a conventional separation / conveyance method, there is, for example, one shown in FIG. In this method, the transmission original 2 of the facsimile machine 1 is separated into one sheet by a feed roller 3 and a separation roller 4 pressed against the feed roller 3, and then conveyed by conveyance rollers 5 and 6 pressed against a pinch roller.

A separation unit 7 shown in FIG. 6 (b) presses friction plates 8 provided on both axial sides of the separation roller 4 in the axial direction with a spring 9 to press the side surfaces of the separation roller 4 to separate them. A resistance torque is generated with respect to the rotation of the roller 4, and FIG.

The plurality of transmission originals 2 sent to the paper feeding unit are separated into one and only the lowermost transmission original 2 is conveyed.

[0004]

However, in the conventional separating / conveying apparatus, the feed roller 3 and the separating roller 4 made of rubber members are always pressed against each other with a constant pressing force to separate and convey the original 2 to be transmitted. Therefore, if there is no separating / transporting operation of the transmission original 2 for a long time, the rubbers adhere to each other, and the rubber surface is damaged or the shape is changed, so that a normal operation cannot be performed.

Further, as shown in FIG. 6B, the separation unit 7 constantly applies pressure to the side surface of the separation roller 4 by pressing the friction plate 8 with a spring 9, and applies a pressing force to the rotation of the separation roller 4.

This is to release the pressure contact between the transport roller and the pinch roller and to release the pressure contact between the feed roller and the separation pad by moving the release plate and the slide plate. However, in this method, when a jam occurs, the user releases the press-contact by using the release plate and the slide plate, and aims to improve the workability at the time of the jam. There is no one that actively changes the crimping place regularly.

Accordingly, the present invention provides a method for stopping the paper separating operation .
Or start counting from the time when the transfer operation is completed ,
Drive the drive system regularly by a fixed amount for each timing data so that the contact time between the separation roller and the rubber of the transfer roller and the rubber does not become longer than the predetermined timing data, that is, so as not to give a long contact time. By stopping and repeating this series of operations, it is possible to prevent sticking of rubber members and damage / change in shape of the rubber surface beforehand, eliminating motor step-out and variations in feed accuracy, and guaranteeing normal operation. , Torque can be generated stably for a long time, double feed and non-feed of originals can be prevented, and the drive system is driven based on the paper detection signal when paper is set to drive the separation roller by a fixed amount. By stopping, the torque can be set to a constant value, and stable separation performance can be obtained,
Further, by correcting the timing data based on the temperature and humidity in the apparatus and driving the drive system in accordance with the environment, prevention of the adhesion of the rubbers, prevention of deformation of the rubber surface, and stability of the torque can be more effectively achieved. An object of the present invention is to provide a separation / transport method and an apparatus thereof that can be implemented.

, The driving is started, the driving is stopped for a certain period of time, and the driving is stopped. This series of programs is repeated and continued. next,
The operation will be described. According to claim 1 and 4 of the present invention, as shown in P ₉ to P ₁₅ of the flowchart of FIG. 5,
When the motor 47 is stopped, the timer 77 starts counting, the count value A of the counted time is greater than the specific timing data TH _0, then stops the motor 47 is driven for a predetermined time, the series of program Since the repetition is continued, it is possible to prevent the rubber from sticking due to the long-term adhesion of the rubber to the outer peripheral portion of the feed roller 34 and the separation roller 35, thereby preventing the torque from increasing, and also causing the damage and the shape change of the rubber surface. Can be prevented. For this reason, the step-out of the motor and the variation in the feeding accuracy can be eliminated, and a normal separation / transport operation can be guaranteed.

Further, since the driving of the motor is continuously performed at regular intervals for a predetermined time according to the specific timing data TH ₀ , the feed roller 34 and the separation roller 35 continue for a long period of time. It can prevent double feeding and non-feeding of originals, and can guarantee normal separation / transport operation without motor step-out and uneven feeding accuracy due to torque increase over a long period of time. .

According to the third aspect of the present invention, the driving time of these motors 47 corresponds to the combination of the temperature T and the humidity RH, that is, the motor 47 corresponds to a change in the environment.
Since the rotation timing data TH of the motor 47 is suitably determined, the number of times the motor 47 is driven for a certain period of time can be reduced as much as possible, so that the above-described rubber breakage and shape change can be prevented beforehand, and the motor can be operated normally due to step-out. Operation can be effectively achieved.

According to a second aspect of the present invention, the motor 47 is driven and stopped for a certain period of time immediately before the document is separated, as shown at P _{1 to} P ₃ in the flowchart of FIG. Since the separation roller 35 rotates for a predetermined time while generating torque on the friction surface between the both end surfaces 35a and the friction plate 57, the separation roller 35 is disposed between the both end surfaces 35a of the separation roller 35 and the friction plate 57 during the document separation operation. In this case, a constant and stable torque is always generated, so that double feed and non-feed of the transmission original 13 can be prevented, and further, when the torque is increased, the motor can be prevented from stepping out.
In addition, even if the surface of the rubber is fixed or changes in shape due to the rotation for a certain period of time between the feed roller 34 and the separation roller 35, uniform and suitable pressure contact can be achieved.

In the above-described embodiment, the case where the time is counted from the end of the separating operation has been described. However, the present invention is not limited to this embodiment. If the sheet is not detected until later, the motor may be stopped assuming that the transport operation has ended, and the timer may start counting.

[0032]

As described above, according to the first and fourth aspects of the present invention, counting is started from the time when the sheet separating operation or the sheet conveying operation is completed , and the rubber and rubber of the separating roller and the conveying roller are counted. Not to be greater than the predetermined timing data, ie,
The drive system is periodically driven for a certain period of time and stopped for each timing data so as not to give a long contact time, and by repeating this series of operations, the adhesion of rubber and the damage / shape of the rubber surface are reduced. Changes can be prevented beforehand, eliminating step-out and variations in feed accuracy of the motor, guaranteeing normal operation, and stably generating torque for a long time, preventing double feed and non-feed of documents. According to the second aspect, the driving system is driven based on the sheet detection signal when the sheet is set to drive the separation roller by a fixed amount, and by terminating the operation, the torque is set to a constant value and stable separation performance is achieved. According to the third aspect, the timing data is corrected based on temperature and humidity, and the driving system is driven in accordance with the environment, thereby preventing the rubbers from sticking, preventing the rubber surface from being deformed, G Click stabilized can be more effectively prevented.
