Abstract

PURPOSE:To stably insert a paper, conveyed at a high speed, between blades, by a method wherein acceleration and deceleration of an impeller are controlled by the rotation speed of the impeller necessary to position a stable take-in stable region for a paper between following blades of the impeller at a point allowing a paper to thrust into an impeller. CONSTITUTION:A driving control circuit 31 receives signals from an impeller rotation amount detecting sensor 30 and a note passage detecting sensor 27, forming an impeller control reference point. An amount, or an impeller rotation phase theta, of an impeller rotated till a note passage detecting sensor 27 detects a note B after the forward end of an impeller 22 is rotated to a point, allowing the note B to thrust into an impeller, is computed by a computing part 35. A driving signal from the table of a memory part 36 is added to a motor 24 through a motor drive circuit 33. When the note B is conveyed to a thrusting- into-impeller point A, the impeller is moved to a note take-in stable region between blades 22 following the position of the thrust-into point A. This enables the note B to be inserted into a taken-in stable region between the blades 22.

Next, the operation of one embodiment of the apparatus of the present invention described above will be explained using the flowchart shown in FIG.

Before the banknote B is conveyed to the impeller 21 by the conveyance path 25, the impeller 21 is rotated by the motor 24 at a standard speed T5. Now, as shown in FIG. 3, when the tip of the blade 22 matches the entry point A of the banknote B into the impeller and continues one rotation thereafter, the impeller rotation amount detection sensor 30 outputs a pulse signal to the drive control circuit 31. . Thereafter, when the banknote B is conveyed by the conveyance path 24 and reaches the banknote passage detection sensor 27 which serves as the impeller control reference point, this sensor 27 detects the tip of the banknote B and outputs the signal to the drive control circuit 31. do. For this reason, the drive control circuit 31 has its calculation section 35
After the tip of one blade 22 reaches the point where banknote B enters the impeller according to the signals from the impeller rotation amount detection sensor 30 and the banknote passage detection sensor 27, the banknote passage detection sensor 27 detects “the impeller 21 until the banknote B is detected”. Calculate the rotation amount, that is, the impeller rotation phase θ.Now, this impeller rotation phase θ
is within the range of impeller rotation phase 0 to θ of Category 1 shown in Table 1, the calculation unit 35 refers to the table of Table 1 stored in the storage unit 36 and determines the drive signal T,
(a speed signal lower than the standard speed T) is calculated. This drive signal T is applied to the motor 24 through a motor drive circuit 33. As a result, the motor 24 decelerates and drives the blade/wheel 21, and when the banknote B reaches the impeller entry point A, the banknote retrieval stable area O~θlit between the next blades 22 is established at the position of this entry point A. can be migrated. As a result, the banknote B can be inserted into the stable take-in region between the blades 22.

After the banknote B enters between the blades 22 (after a certain period of time),
The drive control circuit 31 outputs a standard YrA speed drive command to the motor 24 to return the rotation of the impeller 21 to the standard A4 speed.

Next, when the banknotes B conveyed by the conveyance path 25 are conveyed in the form of several sheets and are conveyed in the form of i, the detection signal of the tip of the overlapped banknote B by the overlapping detection sensor 27 and the detection signal of the tip of the overlapped banknote B by the overlapped banknote B are detected. Based on the subsequent detection signal of the edge, the calculation unit 35 determines that the conveyed banknote B is longer than the specified length of one banknote B, and sends a preset minimum speed drive signal to the motor drive circuit 33. Output. Thereby, the motor 24 rotates the impeller 21 at the lowest speed, so that the stacked banknotes can be taken in between the blades 22.

According to the above-described embodiment, the stability of taking in banknotes by the impeller is improved, and banknotes can be stacked stably and at high speed. Moreover, stacked banknotes can also be captured between the blades.

Note that in the above-described embodiments, the drive control circuit can be configured by a microcomputer or a logic circuit. Further, in the above-described embodiment, the case where banknotes are handled has been described, but it goes without saying that other paper sheets can also be handled.
