Abstract

A product storage device includes: a product storage column storing products aligned in a row in a product storage path; a first gate moving back from and forward to a most downstream area that is downstream of a most downstream product in the product storage path; a second gate disposed in an upstream side with respect to the first gate and moving back from and forward to the most downstream area; a gate operation mechanism keeping the first and second gates in a state of having moved forward to the most downstream area in a standby state and to allow them to move back from the most downstream area when an operation command is given; and a measuring unit measuring the number of taken-out products by counting the number of changes in at least one of the first and second gates from a backward movement to a forward movement.

First claim

What is claimed is:

1. A product storage device comprising:
a product storage column configured to store products in a manner aligned in a row in a product storage path defined by the product storage column;
a first gate configured to move back from and forward to a most downstream area of the product storage column that is downstream of a product positioned in a most downstream side of the product storage path;
a second gate disposed in an upstream side with respect to the first gate and configured to move back from and forward to the most downstream area;
a slider configured to keep the first gate and the second gate in a state of having moved forward to the most downstream area in a standby state, in which the products are prevented from being taken out from the product storage path, and to allow the first gate and the second gate to move back from the most downstream area when an operation command is given; and
a measuring unit that includes sensors and a control unit and that is configured to measure number of products taken out from the product storage path by counting number of changes in at least one of the first gate and the second gate from a backward movement to a forward movement.

2. The product storage device according to claim 1 , wherein the control unit measures the number of products taken out from the product storage path by counting a number of changes in the first gate from a backward movement to a forward movement after the second gate has changed from a backward movement to a forward movement.

3. The product storage device according to claim 2 , wherein the control unit informs an occurrence of abnormality when a predetermined time has passed without detecting a change in the first gate from a backward movement to a forward movement after the second gate has changed from a backward movement to a forward movement.

4. The product storage device according to claim 1 , wherein the second gate includes one or more increased width portions, so that, due to a contact between the one or more increased width portions and a surface of the first gate, the surface of the first gate facing the product storage path, when the second gate moves back along with the first gate from the product storage path and when the second gate moves forward to the product storage path, the second gate moves forward independently.

5. The product storage device according to claim 2 , wherein the second gate includes one or more increased width portions, so that, due to a contact between the one or more increased width portions and a surface of the first gate, the surface of the first gate facing the product storage path, when the second gate moves back along with the first gate from the product storage path and when the second gate moves forward to the product storage path, the second gate moves forward independently.

6. The product storage device according to claim 3 , wherein the second gate includes one or more increased width portions, so that, due to a contact between the one or more increased width portions and a surface of the first gate, the surface of the first gate facing the product storage path, when the second gate moves back along with the first gate from the product storage path and when the second gate moves forward to the product storage path, the second gate moves forward independently.

7. The product storage device according to claim 4 , wherein the slider includes stoppers that move forward to the product storage path in a manner facing each other and, in an ordinary condition, makes a separation distance between the stoppers smaller than a width of the product and, when the product passes through, makes the separation distance larger than the width of the product by being elastically deformed by a press from the product.

8. The product storage device according to claim 7 , wherein, when a replenishing command is given, the slider is in contact with the second gate to force the second gate to move back along with the first gate.

9. The product storage device according to claim 4 , wherein, when a replenishing command is given, the slider is in contact with the second gate to force the second gate to move back along with the first gate.

10. The product storage device according to claim 5 , wherein the slider includes stoppers that move forward to the product storage path in a manner facing each other and, in an ordinary condition, makes a separation distance between the stoppers smaller than a width of the product and, when the product passes through, makes the separation distance larger than the width of the product by being elastically deformed by a press from the product.

11. The product storage device according to claim 10 , wherein, when a replenishing command is given, the slider is in contact with the second gate to force the second gate to move back along with the first gate.

12. The product storage device according to claim 5 , wherein, when a replenishing command is given, the slider is in contact with the second gate to force the second gate to move back along with the first gate.

13. The product storage device according to claim 6 , wherein the slider includes stoppers that move forward to the product storage path in a manner facing each other and, in an ordinary condition, makes a separation distance between the stoppers smaller than a width of the product and, when the product passes through, makes the separation distance larger than the width of the product by being elastically deformed by a press from the product.

14. The product storage device according to claim 13 , wherein, when a replenishing command is given, the slider is in contact with the second gate to force the second gate to move back along with the first gate.

15. The product storage device according to claim 6 , wherein, when a replenishing command is given, the slider is in contact with the second gate to force the second gate to move back along with the first gate.
