Abstract

The present disclosure relates to a garment folding machine including a housing, a loading unit into which a garment is loaded, and a folding unit configured to transfer and fold the loaded garment, in which the folding unit includes a first conveyor configured to transfer the garment from an upper side toward a lower side based on a gravitational direction, a second conveyor disposed below the first conveyor and having a rear end changeable in height, and a folding plate disposed rearward of the second conveyor and configured to fold the garment while rotating, thereby folding the garment with a small number of conveyor belts by changing rotation directions of the conveyor belts during the process of transferring the garment.

First claim

The invention claimed is:

1. A garment folding machine comprising:
a housing;
a loading unit into which a garment is loaded; and
a folding unit configured to transfer and fold the loaded garment,
wherein the folding unit comprises:
a first conveyor configured to transfer the garment from an upper side toward a lower side based on a gravitational direction;
a second conveyor disposed below the first conveyor and having a rear end changeable in height; and
a folding plate disposed rearward of the second conveyor and configured to fold the garment while rotating.

2. The garment folding machine of claim 1 , wherein the loading unit comprises:
a loading plate onto which the garment is loaded; and
a loading conveyor provided above the loading plate and configured to transfer the garment rearward while rotating.

3. The garment folding machine of claim 2 , wherein a speed at which the first conveyor transfers the garment is higher than a speed at which the loading conveyor transfers the garment.

4. The garment folding machine of claim 2 , further comprising:
a control unit configured to control the loading unit and the folding unit,
wherein the loading unit comprises:
a loading conveyor motor configured to provide driving power for operating the loading conveyor; and
a garment input detection sensor disposed rearward of the loading plate and configured to detect the garment, and
wherein the control unit operates the loading conveyor motor when the garment input detection sensor detects the garment.

5. The garment folding machine of claim 1 , wherein a folding gap with a predetermined interval is formed between the first conveyor and the second conveyor, and a distance of the folding gap is smaller than a thickness of the garment.

6. The garment folding machine of claim 1 , wherein the second conveyor transfers the garment forward, and
wherein the garment is transferred rearward when the garment is moved to a predetermined direction change position.

7. The garment folding machine of claim 6 , wherein the rear end of the second conveyor is rotated and moved downward when the garment is moved to the direction change position.

8. The garment folding machine of claim 1 , wherein the folding unit comprises a third conveyor disposed rearward of the second conveyor and configured to transfer the garment having passed over the second conveyor.

9. The garment folding machine of claim 8 , wherein a front end of the third conveyor is rotated and moved downward after the folding plate is rotated.

10. The garment folding machine of claim 1 , further comprising:
a control unit configured to control the loading unit and the folding unit,
wherein the folding unit comprises:
a first conveyor sensor disposed on the first conveyor and configured to detect the garment; and
a second conveyor motor configured to provide driving power for operating the second conveyor, and
wherein the control unit operates the second conveyor motor when the first conveyor sensor detects the garment.

11. The garment folding machine of claim 1 , further comprising:
a control unit configured to control the loading unit and the folding unit,
wherein the folding unit comprises:
a second conveyor motor configured to provide driving power for operating the second conveyor; and
a second conveyor sensor disposed on the second conveyor and configured to detect the garment, and
wherein the control unit changes a rotation direction of the second conveyor motor when the second conveyor sensor detects the garment.

12. The garment folding machine of claim 11 , wherein the folding unit further comprises a second conveyor movement motor configured to rotate the second conveyor to rotate the rear end of the second conveyor, and
wherein the control unit operates the second conveyor movement motor when the second conveyor sensor detects the garment.

13. A garment folding machine comprising:
a housing;
a loading unit into which a garment is loaded; and
a folding unit configured to transfer and fold the loaded garment,
wherein the folding unit comprises:
a first conveyor configured to transfer the garment from an upper side toward a lower side based on a gravitational direction; and
a second conveyor disposed below the first conveyor and having a rear end changeable in height, and
wherein the second conveyor folds the garment by changing a direction, in which the garment is transferred, while transferring the garment.
