The present invention relates to a power drive device such as a banknote counter, in particular, provides a reliable braking with the rapid transmission of the power supplied from the motor to ensure accurate counting of the banknote, and at the same time due to wear of consumable parts such as belts If the partial replacement is unavoidable, the present invention relates to an electromagnetic clutch brake (Electro Magnetic Clutch Brake) that allows simple use of a companionship without disassembling the whole.

Conventional power drive devices generally used in banknote counters, etc. are composed of a power transmission unit for connecting the power of the motor to the load (banknote counter) side, and a braking unit for controlling it. It is connected and installed using the same separate connector.

However, such a drive system is not driven smoothly due to assembly tolerances generated in the process of connecting and installing it, and also due to the residual inertia of the rotation of the body, which has increased abrasion resistance and further rapid operation in controlling the power transmission device. As a result, various problems have been pointed out, such as making the braking position of the load side difficult.

Accordingly, the present applicant has proposed an electronic clutch brake having improved reliability by arranging the power transmission unit and the braking unit in the same axis, but intersecting the power transmission unit and the braking unit.

The proposed power drive device, as shown in FIG. 1, is fixed to the body of a banknote counter (not shown) and supports brackets 13 which are bent and protruded by supporting supports 11 and 12 at both ends. ), The support shaft 11, 12 on the bracket 13, and a rotation shaft 15 which is installed as a bearing 14, and are installed along the rotation shaft 15 and attached to the support 12 on one side of the bracket 13. The clutch yoke 18 supported by the fixed brake yoke 16 and the fixed pin 17 and the rotary yoke 15 are provided to receive the electromotive force of the clutch yoke 18 so as to transmit power from the motor to the rotary shaft. And a clutch pulley 22 installed on one side and a clutch pulley 22 which is intermittently driven by a motor 19 and a belt 21 connected to a power source and an intermittent drive, and the brake yoke 16 is energized. The brake armature 24 and the brake boss 25 adsorbed thereto to regulate the rotating shaft 15, And it is made of a brake pulley 26 which is struck on the rotating shaft 15 in order to control the power connected to the load side, as well as performing the function of continuously connecting or disconnecting the power of the motor to the load side quickly and accurately In this case, it is possible to guarantee the reliable operation of the counter for counting banknotes connected to the load side.

However, such a device also follows the rotating shaft 15 when the belts 21 and 21a, which are respectively connected to the clutch pulley 22 and the brake pulley 26, need to be cut and replaced due to wear due to prolonged use. Not only does the work has to be done by disassembling the various fixed parts in turn, and the rotating shaft 15 has to be separated from the supporting bracket 13, but also the eccentricity of which the rotation center is not accurately adjusted through frequent assembly processes. This caused severe noise and vibration, resulting in a significant reduction in endurance life.

This proposal was devised in view of the above-mentioned problems in the related art, and it is possible to precisely and promptly count bills through the reduction of wear resistance by suppressing the cause of eccentricity by matching the rotation center with the convenience of assembly. Its main purpose is to provide an electromagnetic clutch brake.

Another object of this paper is that installation and replacement of worn parts are easy, and even if the brake body is removed from the supporting bracket for the belt replacement, which is a consumable, the brake assembly is assembled on the rotational axis without distraction. It is possible to provide an electromagnetic clutch brake with an improved structure that is easy to maintain.

In addition, the present invention for achieving the above object is fixed to the body of the banknote counter, the support bracket which is configured to protrude two supports in different bending directions to the upper side, and detachable on the bracket It consists of a brake assembly that is installed, the clutch yoke and the brake yoke of the brake assembly is integrally fixed to both ends of the bearing housing in which a pair of bearings on both sides of the sleeve so that they can be located on the same line of the sieve suppressed eccentricity Configure.

The support bracket for supporting the brake assembly may include a housing support bent to intersect in the axial direction so that the bearing housing, which is held as a bearing on the rotation shaft, may be coupled to the bowl, and bent to mount an end of the rotation shaft. Characterized in that it comprises a shaft support that is formed integrally with the U-shaped groove portion open to the upper end.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is an exploded perspective view showing a preferred embodiment of the present invention, and FIG. 3 is a longitudinal sectional view showing the state of use of FIG. 2, wherein the electromagnetic clutch brake of the present invention has two front and rear sides of different bending directions. It consists of a support bracket (110) protruding the support (112, 114) upwards, and a brake assembly (100) detachably installed on such a bracket (110).

The support plate 100 is fixed to the body of the bill counter and the clutch yoke 122 and the brake yoke 124 along the rotating shaft 120 on the upper portion of the bearing 121, 123, respectively The brake assembly 100 is installed.

That is, while the rotor 126 and the clutch yoke 122 and the brake yoke 124 on the rotating shaft 120, the bearings 121 and 123 are flushed out, so that both yokes can be fixed on the same line as the rotating shaft 120. A pair of bearings 121 and 123 supporting the 122 and 124 is installed in the bearing housing 130, and a sleeve 125 having a predetermined thickness is inserted between the bearings 121 and 123. In order to provide a stable assembly structure in which eccentricity is suppressed by installing the pair of yokes 122 and 124, respectively, on the outside of the bearing housing 130.

Then, the brake armature 127 and the clutch armature 129 are respectively affixed to their ends, and the clutch pulley 132 which is extended to the rotation shaft 120 and the bearing 128 on the outside of the clutch armature 129. To integrally address the power of the motor 135 to be selectively transmitted to the rotating shaft 120 via the belt 131, the brake arm 127 is a brake boss fixed to the end of the rotating shaft 120 The brake pulley 134 is installed along the rotational shaft 120 to achieve an integrated structure with the 136 and configured to transmit power to the load side.

In this way, the brake assembly 100 assembled along the rotating shaft 120 is detachably installed on the support bracket 110 again. For this purpose, the kit 110 is bent upwardly while maintaining the direction crossing each other. The bolt insertion hole 115 of one side support 114 and the insertion hole 137 to be machined in the side of the bearing housing 130 are matched and then assembled as a bolt 138. On the other side of the support 112, a U-shaped flap 113 that is open to the upper portion of the bearing 139 fixed to the end of the rotary shaft 120 is mounted and then fixed with a cover for preventing the release of the bearing (l40) to give a solid brake To complete the assembly.

The electric clutch brake of the present invention configured as described above has a clutch pulley connected to the pulley 135b on the drive shaft 135a and the belt 131 when a power is applied to the motor 135 and the motor drive shaft 135a starts to rotate. 132 is rotated, wherein the clutch pulley 132 is retained as a bearing 132 along the rotation shaft 120 and one side of the clutch pulley 129 is integral with the clutch armature 129 to power the motor 135. Only the clutch pulley 132 that did not transmit to the rotating shaft 120 will show a free idle state.

When the electromotive force is generated by applying power to the clutch yoke 122 that is firmly mounted on one side support 114 of the support Brekit 110 in this state, the electromotive force generated in the clutch yoke 122 is the rotor 126. Since the clutch amateur 129 is adsorbed through the rotor, the rotor 126 and the clutch amateur 129 are configured to have a unitary structure due to mutually strong force.

Therefore, the rotor 126 coupled to the clutch armature 129 with strong suction force can transmit the power transmitted from the motor drive shaft 135a to the rotation shaft 120, and the clutch amateur 129 installed on the rotation shaft 120. Rotation of the brake pulley 134 is connected to the rotating shaft 120 again, the power transmission to the load side through the belt 133 is made quickly and smoothly.

In such a power transmission process, when the power source is disconnected from the clutch yoke 122 driving the rotating shaft 120 to remove the electromotive force of the clutch, the clutch armature 129 and the rotor 126 are the first separation distance. While maintaining the air gap of 0.3mm, it is returned to the idle state of only the clutch pulley 132 which is separated and remains as a bearing 128 on the rotating shaft 120, but the rotating shaft 120 which is being rotated by receiving power is rotated. Due to the residual inertia, the immediate braking is virtually impossible.

Therefore, in order to preserve the purified braking position on the load side, a desired braking device is required. Once the braking position is determined, the power applied to the clutch yoke 122 is immediately cut off and the rotating shaft 120 is pulled out. In addition to releasing from 132, a separate brake device is operated for rapid braking of the rotating shaft 120 which continues to rotate due to residual inertia.

At this time, the brake device consisting of a brake yoke 124 on one side of the bearing housing 130 that is held on the rotating shaft 120 as a bearing 123 and a brake arm 127 fixed on the rotating shaft 120, the clutch yoke ( In addition to the power cut off of the 122, it is preferable to configure the power switching method for applying a new power to the brake yoke 124.

In other words, when the power applied to the clutch yoke 122 is cut off as described above, and the clutch amateur 129 and the rotor 126 fall due to the loss of electromotive force, the power transmission system transmitted to the rotating shaft 120 is cut off. The clutch pulley 132 and the rotating shaft 120, which are idling by the motor 135, are freely rotated, respectively, and the rotating shaft 120 itself is separated, thereby making unnecessary rotation of the clutch yoke 122. The power supply of the brake yoke 124 is cut off at the same time, and the brake armature 127 is sucked by the electromotive force generated by the power applied to the brake yoke 124, and the speech is applied to the rotary shaft 120 and the rotary shaft. The brake pulley 134 and the belt 133 connected thereto are to be subjected to rapid braking.

In using the electromagnetic clutch brake of this paper, the belt pulleys 132 and 133, which are connected to the clutch pulley 132 and the brake pulley 134, respectively, must be cut and replaced due to wear caused by prolonged use. Even if the parts, etc. assembled on the rotating shaft 120 are not disassembled, the bolts 138 assembled to both supports 112 and 114 of the support Brekit 110 are sequentially released to release the bearing housing ( While allowing 130 to be separated from the support 114, the end of the rotating shaft 120 fixed to the other support 112 can also be easily separated upwards by the removal of the bearing departure preventing cover 140. Will be.

Therefore, a pair of yokes 122 and 124 and a driving pulley 132 and l34 are installed along the rotating shaft 120 as described in detail through the above embodiments, but the pair of yokes 122 and 124 are provided. Is inserted into the bearing housing 130 so as to be positioned on the same line as the rotation shaft 120, such a brake assembly 100 is again removable on both supports 112, 114 of the support Brekit 110. The electronic clutch brake of the present invention, which is installed in such a manner, requires only a simple operation of simply detaching the assembly from the supporting bracket without disassembling the brake assembly from the rotating shaft even if the belt is frequently replaced with the convenience of assembly. It does not change the center of rotation or change the funnel, so that it is possible to maintain the condition consistently as well as to significantly reduce the wear resistance and to quickly count bills. Loss can provide improved benefits.
