When the driving force of the input shaft 37 of the skinning device 30 is transmitted to the sprocket 116a without being shifted, the driving speed of the sorting transmission mechanism 116 and the driving speed of the skinning device 30 are the same. Therefore, the driving speed of the skinning device 30 can be detected based on the driving speed of the sorting transmission mechanism 116 (the driving speed related to the skinning device 30). Instead of the sorting transmission mechanism 116, the processing transmission mechanism 114 (the transmission system related to the skin peeling device 30) may be provided with the detection unit 122.

Specifically, the conveyance detection unit 123 is configured as shown in FIG.
Of the drive shaft 7a of the transport device 7, a rotating body 127 is provided at a portion opposite to the input side so as not to be relatively rotatable. The conveyance detection unit 123 is attached to the side of the conveyance case in the conveyance device 7 via a bracket 128. The conveyance detection unit 123 detects the rotation speed of the rotating body 127 as the driving speed of the conveyance device 7. Specifically, the conveyance detection unit 123 is configured by a rotary encoder.
