A belt or a chain of a conveyor is provided with parts such as a sprocket rotatable at both ends so as to be able to rotate an endless track, and one of them is connected to a drive shaft so as to transmit a rotational force. Therefore, as the drive shaft rotates, the belt conveys the object while rotating around the infinite orbit.

The conveyor belt or chain is driven by a caterpillar chain, and the conveyor is operated or stopped depending on whether the caterpillar chain is driven or not.

These conveyors are very diverse and used in a variety of applications, particularly in areas such as automotive assembly.

Usually, the drive shaft of the caterpillar chain is connected to a drive energy source such as a motor by a power transmission device. As the power transmission device, gears, belts, chains, and the like can be used.

The conventional caterpillar chain drive apparatus has a structure in which a sprocket is fixed to one motor rotation axis, a sprocket is fixed to a drive shaft, and then sprockets are connected by a chain so that the driving force of the motor is transmitted to the drive shaft.

However, in the conventional caterpillar chain drive device, when the motor fails, all the conveyor devices must be stopped and replaced with a new motor, or the motor must be repaired.

The objects, features and advantages of the present invention will become more apparent from the following detailed description. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The caterpillar chain drive apparatus according to the preferred embodiment of the present invention includes a drive shaft 60, a first rotation shaft 41, a first motor 40, a second rotation shaft 51, and a second motor 50.

1 and 2, the drive shaft 60 is a shaft for driving the caterpillar chain 71. The drive shaft 60 is assembled with the caterpillar chain 71 to provide a driving force. The driving shaft 60 receives driving force from the first motor 40 or the second motor 50 and drives the caterpillar chain 71. The drive shaft 60 is fixed to the stationary frame 10.

The drive shaft (60) is assembled by sprockets on the upper part of the drive shaft (61), and the caterpillar chain (71) is also assembled on the lower part by a sprocket. Therefore, the drive force is input through the upper drive chain 61, and the drive force is output through the caterpillar chain 71.

The first rotation shaft 41 transmits a rotational driving force to the driving shaft 60 via the driving chain 61. Referring to FIG. 7, the first rotary shaft 41 is connected to the drive shaft 60 via the drive chain 61.

The first motor (40) drives the first rotation shaft (41). 7, the first rotary shaft 41 is rotated by the rotational driving force of the first motor 40 and the first rotary shaft 41 is connected to the driving shaft 60 through the driving chain 61, When the first motor 40 is driven, the driving shaft 60 is rotationally driven.

It is needless to say that the first and second motors 40 and 50 may be replaced by components such as an engine that can provide rotational driving force in the same manner as the first and second motors 40 and 50 are driving sources for providing rotational driving force.

The first and second motors 40 and 50 are fixed to the motor mounting 30, and the motor mounting 30 is fixed to the movable frame 20. Therefore, it moves linearly with the moving frame.

The second rotation shaft 51 transmits a rotational driving force to the drive shaft 60 via the drive chain 61 when the first rotation shaft 41 stops. 9, when the first motor 40 stops due to a failure or the like, the second rotation shaft 51 and the drive shaft 60 are connected to the drive chain 61, .

The second motor (50) drives the second rotation shaft (51). The relationship between the second motor 50 and the second rotation shaft 51 is the same as the relationship between the first motor 40 and the first rotation shaft 41 described above.

Therefore, the drive shaft 60 can be driven by the first motor 40 or the second motor 50, and in particular, when one of the motors fails, It is possible to reliably reduce the work delay.

A belt may be used instead of the drive chain 61, and a sprocket may be omitted when a belt is used.

The driving device has a fixed frame (10). The fixed frame 10 supports the drive shaft 60.

The driving device includes a moving frame 20 to which the first motor 40 and the second motor 50 are fixed. The movable frame 20 is installed so as to be able to slide in a linear direction with respect to the fixed frame 10 on a horizontal plane.

The driving device includes a plurality of tension springs 12 connecting the fixed frame 10 and the movable frame 20 so as to adjust the tension of the driving chain 61. 4, the spring 12 has one end fixed to the fixed frame 10 and the other end fixed to the movable frame 20. The driving shaft 60 and the first and second rotating shafts 41 and 51, the tension of the driving chain 61 is adjusted.

A guide rod 11 for connecting the stationary frame 10 and the movable frame 20 is inserted and fixed to the center of the spring 12 and is fixed to the drive chain 61 by adjusting the length thereof. The limit of the tension is controlled. Of course, the operator can quickly adjust the value through a scale fixed to the fixed frame 10.

A driven shaft 70 connected to the drive shaft 60 by a caterpillar chain 71 is installed in the moving frame 20. [ 5, the driven shaft 70 is assembled together with the drive shaft 60 and the caterpillar chain 71 is coupled with the drive shaft 60 to drive the caterpillar chain 71, .

5, a sprocket is provided on the drive shaft 60 on one side of the caterpillar chain 71 and a sprocket is mounted on the driven shaft 70 on the opposite side to drive the caterpillar chain 71 . A tension adjuster 73 is installed inside the caterpillar chain 71, and guide rollers 72 are installed outside the caterpillar chain 71. Therefore, the caterpillar is driven in a linear direction passing between the caterpillar chain 71 and the guide roller 72. Wherein the caterpillar is guided in a linear direction by a caterpillar guide frame (80).

The operation of the caterpillar chain driving apparatus will be described with reference to FIGS. 7 and 8. FIG. First, the driving shaft 60 is connected to the first rotating shaft 41. [

When power is applied to the first motor 40 to start operation, the first rotation shaft 41 is rotationally driven. The rotational driving force of the first rotating shaft 41 is transmitted to the driving shaft 60 through the driving chain 61 so that the driving shaft 60 is rotated.

As the drive shaft 60 rotates, the driven shaft 70 rotates along with the rotation of the drive shaft 60. Eventually, the caterpillar chain 71 is driven. As the caterpillar chain 71 is driven, the caterpillar is linearly driven and transported between the caterpillar chain 71 and the guide roller 72.

9, when the operation of the first motor 40 is disabled due to failure or the like during the operation in the above-described manner, the drive chain 61 is separated from the first rotation shaft 41 and released , And the drive chain (61) is engaged with the sprocket of the second rotation shaft (51). Then, when assembly and disassembly are completed, power is applied to the second motor 50 and the operation is resumed.

When the second motor 50 is operated, the second rotation shaft 51 is rotationally driven, and the drive shaft 60 is driven by the power transmission of the drive chain 61. When the drive shaft 60 is driven, the caterpillar chain 71 is driven as described above.

As shown in FIG. 9, if a cause such as a failure of the motor occurs, the operation can be restarted immediately after removing and assembling only the drive chain 61, so that the operation delay due to the failure of the motor can be minimized.

On the other hand, a second embodiment of the present invention is shown in Fig. As shown in the drawing, the present embodiment is different from the previous embodiment in that a single chain is not used but a drive chain 161 and 162 are connected to each motor.

The caterpillar chain drive device includes a drive shaft 160 for driving the caterpillar chain 71, a first rotation shaft 141 for transmitting a rotational drive force to the drive shaft 160 via a first drive chain 162, A first motor for driving the first rotation shaft 141 and a second rotation shaft 151 for transmitting a rotational driving force to the drive shaft 160 via the second drive chain 161; And a second motor for driving the second motor.

Here, during the rotation of the first motor, the second driving chain 161 idles and the first driving chain 162 idles during the rotation of the second motor.

It is needless to say that the first and second drive chains may include other power transmission means such as a belt in addition to the chain.

10, bearings 142 and 152 are installed on the outer surfaces of the first and second rotary shafts 141 and 151, sprockets are installed on the outer surfaces of the bearings 142 and 152, And can be fixed to or released from the first rotation shaft 141 and the second rotation shaft 142 by pins 143 and 153.

Therefore, when the pins 143 and 153 are inserted, the rotation shafts 141 and 151 are rotated. When the pins 143 and 153 are removed, only the bearings 142 and 152 are rotated, and the idle rotation is performed.

10, the pin 143 is inserted into the first rotation shaft 141 so that the driving force of the first motor can be transmitted to the driving shaft 160. In the second rotation shaft 151, The pin 153 is removed and the idle rotation state is established. Accordingly, only the driving force of the first motor is transmitted to the driving shaft 160.

The pin 143 of the first rotation shaft 141 is removed and the pin 153 is inserted into the second rotation shaft 151. In this state, Next, the second motor is driven to immediately restart the operation.

Therefore, the insertion and removal of the pins 143 and 153 have the same effect as the replacement of the motor.

Although the bearings 142 and 152 and the pins 143 and 153 are used in the rotary shafts 141 and 151 to control the idle rotation and the rotational restraint, the drive shafts 160 and 162 may be driven by bearings And pins may be assembled in the same manner.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
