Smart distribution vehicle and control method therefor

1 . A smart distribution vehicle comprising:

a fork arm;

a fork which is coupled to the fork arm and which extend toward a front side of the fork arm;

an electromagnet mounted on the front side of the fork arm;

a clamp disposed adjacent to the fork arm and which has a gripper for restricting a movement of the object loaded on the fork, wherein the gripper comprises a first contact part that is in contact with a first side of a lower end surface of the object and a second contact part that is in contact with a second side of the lower end surface of the object; and

a control part including a processor and configured to:

control whether to supply a current to the electromagnet by determining whether an object has a magnetic property in response that the object is seated on the fork arm;

control a grip of the gripper in response that the object is seated on the fork arm, and

adjust a distance between the first contact part and the second contact part based on a torque of a motor in response that the object is seated on the fork arm, thereby controlling the grip of the gripper.

2 . The smart distribution vehicle of claim 1 , further comprising a push-button switch disposed on the front side of the fork arm,

wherein the control part is configured to determine whether the object is seated on the fork arm according to an on-off of the push-button switch.

3 . The smart distribution vehicle of claim 1 , further comprising a magnetic detection sensor disposed on the front side of the fork arm,

wherein the control part is configured to determine whether the object has the magnetic property through the magnetic detection sensor.

4 . The smart distribution vehicle of claim 1 , wherein the control part is configured to control the electromagnet to fix the object when it is determined that the object has the magnetic property.

5 . The smart distribution vehicle of claim 4 , further comprising:

a power supply device; and

an electronic switch connected between the electromagnet and the power supply device,

wherein the control part is configured to control the electronic switch such that the electronic switch is in a turned-on state in response that it is determined that the object has the magnetic property.

6 . The smart distribution vehicle of claim 5 , wherein the control part is configured to control the electronic switch such that the electronic switch is in a turned-off state in response that it is determined that the object does not have the magnetic property.

7 . The smart distribution vehicle of claim 1 , wherein the control part is configured to determine whether the gripper performs the grip normally by detecting whether the torque of the motor reaches a target torque, and

the control part is configured to adjust a position of the clamp in response that the torque of the motor does not reach the target torque.

8 . A method for controlling a smart distribution vehicle, the method comprising:

loading an object on a fork that extends toward a front side of a fork arm;

detecting whether the object is seated on the fork arm in response that the object is loaded on the fork;

controlling whether to supply a current to an electromagnet mounted on the front side of the fork arm by determining whether the object has a magnetic property in response that the object is seated on the fork arm; and

controlling a grip of a gripper in response that the object is seated on the fork arm, the gripper being provided on a clamp that is disposed adjacent to the fork arm;

wherein the controlling the grip comprises adjusting a distance between a first contact part and a second contact part based on a torque of a motor, the first contact part and the second contact part being provided on the gripper.

9 . The method of claim 8 , wherein the detecting comprises determining whether the object is seated on the fork arm according to an on-off of a push-button switch disposed on the front side of the fork arm.

10 . The method of claim 8 , wherein the controlling whether to supply the current comprises determining whether the object has the magnetic property through a magnetic detection sensor disposed on the front side of the fork arm.

11 . The method of claim 8 , wherein the controlling whether to supply the current comprises:

magnetizing the electromagnet by supplying the current to the electromagnet so that an attraction acts on the electromagnet and the object in response that it is determined that the object has the magnetic property; and

blocking the current supplied to the electromagnet in response that it is determined that the object does not have the magnetic property.

12 . The method of claim 8 , wherein controlling whether to supply the current further comprises controlling a turned-on state of an electronic switch according to the magnetic property of the object, the electronic switch being connected between the electromagnet and a power supply device.

13 . The control method of claim 8 , further comprising:

determining whether the gripper performs the grip normally by detecting whether the torque of the motor reaches a target torque; and

adjusting a position of the clamp in response that the torque of the motor does not reach the target torque.
