Embodiment Construction

[0029] Below, refer to Figure 1 to Figure 8 One embodiment of the detection device according to the present invention will be described. The detection device according to the present embodiment is an egg crack detection device that detects the presence or absence of egg cracks (cracks) by setting the detection object to be detected as an egg (in particular, an egg). In addition, in each drawing, the dimensional ratios in the drawings do not necessarily match the actual dimensional ratios.

[0030] Such as figure 1 As shown in , the detection device 1 according to this embodiment has: a conveying device 2 for conveying the egg 100 along the conveying direction D1, and a plurality of devices arranged above the conveying device 2 for knocking on the egg 100 conveyed by the conveying device 2. Knocking unit 3, and a control unit 4 for controlling the device. Furthermore, the detection device has an input unit 5 for inputting information related to the detection, and an output ...

Abstract

The present invention relates to a detection device 1, which has: a hammer part 31 that strikes a detection object 100, a detection part 33 that detects the vibration generated by the hammer part 31 hitting the detection object 100, and a vibration detected based on the detection part 33. The calculation part 41 which calculates the number of times the hammer part 31 collides with the detection object 100 with respect to one knocking operation of the hammer part 31 by vibration, and the determination part which judges whether the detection object 100 is good or bad based on the number of times calculated by the calculation part 41 42.

Description

technical field [0001] The present invention relates to a detection device including a hammer that strikes a detection object, and a detection unit that detects vibration generated by the hammer striking the detection object. Background technique [0002] Conventionally, as a detection device, a detection device having a hammer that strikes a detection object (for example, an egg, etc.) and a detection portion that detects vibration generated by the hammer hitting the detection object is known (for example, Patent Document 1). Such a detection device detects a detection object based on the sound signal detected by the detection unit. [0003] However, such a detection device detects a detection target by converting the sound signal detected by the detection unit into a spectral intensity of a frequency band. Therefore, in such a detection device, the detection accuracy decreases due to changes in the size of the detection object, changes in the detection environment, and th...
