Abstract

Provided is an automatic bed conveying system capable of reducing positional deviation by alleviating the impact on a person lying on a bed when the bed starts and stops. The bed comprises a bed having a bottom plate provided with a back bottom plate, a knee bottom plate and a foot bottom plate, a driving unit for driving the bed, a first control part for controlling the bed to be automatically conveyed to a destination by the driving unit, and a second control part for lifting and falling the back bottom plate, the knee bottom plate and the foot bottom plate, wherein when the bed starts to move towards the destination, the second control part executes a first action for lifting the back bottom plate when the travelling direction of the bed is the foot bottom plate side, executes a second action for lifting the knee bottom plate and the foot bottom plate when the travelling direction of the bed is the back bottom plate side, and executes a second action when the travelling direction of the bed is the foot bottom plate side when the bed approaches to the destination and stops.

Claims (9)

1. An automatic bed conveying system, comprising: a bed having a base plate provided with a back base plate, a knee base plate, and a foot base plate; A driving unit that drives the bed; A first control part for controlling the bed to be automatically conveyed to a destination by the driving unit, and A second control unit that lifts and lowers the back floor, the knee floor, and the foot floor, When the bed starts to move toward the destination, the second control unit performs a first operation of raising the back floor when the traveling direction of the bed is the foot floor side, performs a second operation of raising the knee floor and the foot floor when the traveling direction of the bed is the back floor side, When the bed is stopped near the destination, the second control unit executes the second operation when the traveling direction of the bed is the foot floor side, and executes the first operation when the traveling direction of the bed is the back floor side.
2. The automated bed transport system of claim 1, wherein, The second control unit further performs the second operation when the traveling direction of the bed is the foot bottom plate side and further performs the first operation when the traveling direction of the bed is the back bottom plate side when the bed starts to travel toward the destination, When the bed reaches the destination and stops, the second control unit further executes the first operation when the traveling direction of the bed is the foot bottom plate side, and further executes the second operation when the traveling direction of the bed is the back bottom plate side.
3. The automated bed transport system of claim 1, wherein, The second control unit performs a third operation of raising the back floor higher than the first operation during start and stop of the bed toward the destination.
4. The automated bed transport system of claim 1, wherein, The second control portion prohibits the operation of the person lying on the bed during the start and stop of the bed toward the destination.
5. The automated bed transport system of claim 1, wherein, The bed also has a lifting mechanism which lifts the base plate, The lifting mechanism positions the floor in a lowered position during start and then stop of the bed towards the destination.
6. The automated bed transport system of claim 1, wherein, And a notification unit that reports to a person lying on the bed when the second control unit executes the first operation and the second operation.
7. The automated bed transport system of claim 1, wherein, The drive unit is provided with casters which, The drive unit further includes a caster lock control unit that suppresses rotation of the caster.
8. The automated bed transport system of any of claims 1 to 7, wherein, The vehicle further comprises an obstacle judging part, wherein, When the obstacle determination unit determines that there is an obstacle in the traveling direction of the bed while the bed is started and stopped toward the destination, the second control unit performs a third operation of raising the back floor higher than the first operation when the traveling direction of the bed is the back floor side, and performs a fourth operation of raising the knee floor and the foot floor higher than the second operation when the traveling direction of the bed is the foot floor side.
9. The automated bed transport system of claim 8, wherein, The bed also has a load cell for determining the weight of a person lying on the bed, The second control unit adjusts the lifting angles of the back floor, the knee floor, and the foot floor in the first operation, the second operation, the third operation, and the fourth operation based on the weight acquired by the load sensor.

Description

Automatic bed conveying system Technical Field Embodiments of the present invention relate to an automatic bed transport system. Background Conventionally, automatic transport systems for wheelchairs, automobiles, and the like have been disclosed. These automatic conveyance systems acquire route information when information of a destination is input, and automatically travel to the destination. When the automatic conveyance system is applied to a bed, since a person is lying on the bed, an impact is applied to the person lying on the bed at the start and stop, and the position of the person lying on the bed may be shifted. Prior art literature Patent literature Patent document 1 Japanese patent publication No. 7117743. Patent document 2 Japanese patent application laid-open No. 2004-313587. Disclosure of Invention Technical problem to be solved by the invention An object of an embodiment of the present invention is to provide an automatic bed conveying system capable of reducing positional displacement by reducing impact on a person lying on a bed when the bed starts and stops. Technical means for solving the technical problems An automatic conveyance system according to an embodiment of the present invention includes a bed having a floor provided with a back floor, a knee floor, and a foot floor, a driving unit that drives the bed, a first control unit that controls the bed to be automatically conveyed to a destination, and a second control unit that lifts and lowers the back floor, the knee floor, and the foot floor, wherein when the bed starts to move toward the destination, the second control unit performs a first operation that lifts the back floor when a traveling direction of the bed is on a foot floor side, and performs a second operation that lifts the knee floor and the foot floor when the traveling direction of the bed is on the back floor side, and when the bed stops approaching the destination, the second control unit performs the second operation when the traveling direction of the bed is on a foot floor side, and when the traveling direction of the bed is on the back floor side.
