Title:
SPEED DISPLAY DEVICE, SHEET LAYING DEVICE AND SHEET LAYING METHOD
Document Type and Number:
Japanese Patent JP2022066048
Kind Code:
A
Abstract:
To provide a speed display device which allows a worker to visually recognize a numeric value with which the worker may know a travel speed at which a sheet laying device travels with excellent visibility, a sheet laying device having the speed display device and a sheet laying method using the sheet laying device.SOLUTION: A waterproof sheet joint device 1 applied with a sheet laying device of the present invention is used when joining (laying) a waterproof sheet 100 (sheet) on a floor surface as a building frame, and includes a travel system 9 which has wheels 92B (rollers) supported in a rotatable manner and travels along a forward direction by the rotation of the wheels 92B. The waterproof sheet joint device 1 includes a speed display device of the present invention as a speed system 60. The speed system 60 comprises: a dynamo 62 which is transmitted with rotational force of the wheels 92B generated by the travel along the forward direction of the joint device 1; and a display part 61 which displays a numeric value based on a voltage value of a current generated by the dynamo 62 based on the transmitted rotational force.SELECTED DRAWING: Figure 1
