Abstract

A conveying equipment (50) includes a first conveyance line (60) having a first upper rotation conveyance unit (61a) and a first lower rotation conveyance unit (61b) and a second conveyance line (70) having a second upper rotation conveyance unit (71a) and a second lower rotation conveyance unit (71b). In the conveying equipment (50), between the first conveyance line (60) and the second conveyance line (70), an adjustment rotation conveyance unit (80) that rotates while gripping at least one of a flange upper portion (17a) and a flange lower portion (17b) of a bottle (10) is provided. The adjustment rotation conveyance unit (80) has an upper gripping part (81a) that is provided to be openable and closable and grips the flange upper portion (17a), and a lower gripping part (81b) that is provided to be openable and closable and grips the flange lower portion (17b).

First claim

The invention claimed is:

1. A conveying equipment for a bottle having a flange portion, comprising:
a first conveyance line comprising a first upper rotation conveyance unit that rotates while gripping a flange upper portion located above the flange portion of the bottle and conveys the bottle and a first lower rotation conveyance unit that rotates while gripping a flange lower portion located below the flange portion of the bottle and conveys the bottle; and
a second conveyance line comprising a second upper rotation conveyance unit that rotates while gripping the flange upper portion of the bottle and conveys the bottle and a second lower rotation conveyance unit that rotates while gripping the flange lower portion of the bottle and conveys the bottle,
wherein between the first conveyance line and the second conveyance line, an adjustment rotation conveyance unit that rotates while gripping at least one of the flange upper portion and the flange lower portion of the bottle is provided, and
the adjustment rotation conveyance unit comprises an upper gripping part that is provided to be openable and closable and grips the flange upper portion of the bottle and a lower gripping part that is provided to be openable and closable and grips the flange lower portion of the bottle.

2. The conveying equipment according to claim 1 , wherein the adjustment rotation conveyance unit uses one of the upper gripping part and the lower gripping part to receive the bottle from the first lower rotation conveyance unit or the first upper rotation conveyance unit of the first conveyance line, and uses the one gripping part to transfer the bottle to the second lower rotation conveyance unit or the second upper rotation conveyance unit of the second conveyance line.

3. The conveying equipment according to claim 1 , wherein the adjustment rotation conveyance unit uses one of the upper gripping part and the lower gripping part to receive the bottle from the first lower rotation conveyance unit or the first upper rotation conveyance unit of the first conveyance line, and, while the adjustment rotation conveyance unit rotates and conveys the bottle, changes gripping of the bottle from the one gripping part to the other gripping part, and the adjustment rotation conveyance unit uses the other gripping part to transfer the bottle to the second upper rotation conveyance unit or the second lower rotation conveyance unit of the second conveyance line.

4. An adjustment rotation conveyance unit provided between a first conveyance line comprising a first upper rotation conveyance unit that rotates while gripping a flange upper portion located above the flange portion of the bottle and conveys the bottle and a first lower rotation conveyance unit that rotates while gripping a flange lower portion located below the flange portion of the bottle and conveys the bottle, and a second conveyance line comprising a second upper rotation conveyance unit that rotates while gripping the flange upper portion of the bottle and conveys the bottle and a second lower rotation conveyance unit that rotates while gripping the flange lower portion of the bottle and conveys the bottle, the adjustment rotation conveyance unit rotating while gripping at least one of the flange upper portion and the flange lower portion of the bottle, the adjustment rotation conveyance unit comprising:
an upper gripping part provided to be openable and closable and gripping the flange upper portion of the bottle; and
a lower gripping part provided to be openable and closable and gripping the flange lower portion of the bottle.

5. A conveyance method of a bottle having a flange portion, comprising:
a first conveyance step of conveying a bottle using a first conveyance line comprising a first upper rotation conveyance unit that rotates while gripping a flange upper portion located above the flange portion of the bottle and conveys the bottle and a first lower rotation conveyance unit that rotates while gripping a flange lower portion located below the flange portion of the bottle and conveys the bottle;
a second conveyance step of conveying the bottle using a second conveyance line comprising a second upper rotation conveyance unit that rotates while gripping the flange upper portion of the bottle and conveys the bottle and a second lower rotation conveyance unit that rotates while gripping the flange lower portion of the bottle and conveys the bottle; and
an adjustment conveyance step of, between the first conveyance step and the second conveyance step, conveying the bottle from the first conveyance line to the second conveyance line using an adjustment rotation conveyance unit that rotates while gripping at least one of the flange upper portion of the bottle and the flange lower portion of the bottle,
wherein the adjustment rotation conveyance unit comprises an upper gripping part that is provided to be openable and closable and grips the flange upper portion of the bottle and a lower gripping part that is provided to be openable and closable and grips the flange lower portion of the bottle.

6. The conveyance method according to claim 5 , wherein the adjustment conveyance step comprises:
a receiving step of using one of the upper gripping part and the lower gripping part to receive the bottle from the first lower rotation conveyance unit or the first upper rotation conveyance unit of the first conveyance line; and
a transfer step of using the one gripping part to transfer the bottle to the second lower rotation conveyance unit or the second upper rotation conveyance unit of the second conveyance line.

7. The conveyance method according to claim 5 , wherein the adjustment conveyance step comprises:
a receiving step of using one of the upper gripping part and the lower gripping part to receive the bottle from the first lower rotation conveyance unit or the first upper rotation conveyance unit of the first conveyance line;
a gripping change step of changing gripping of the bottle from the one gripping part to the other gripping part while the adjustment rotation conveyance unit rotates and conveys the bottle; and
a transfer step of using the other gripping part to transfer the bottle to the second upper rotation conveyance unit or the second lower rotation conveyance unit of the second conveyance line.
