Description of the Related Art As shown in FIG. 3, a conventional conveying device of this type excites a long belt-shaped conveying plate 1 with an excitation means 2 provided at one end, and this excitation action causes the conveying plate to move. The powder 3 on the conveyor plate 1 is moved by the arrow
It was configured to be transported in the direction. As the excitation means 2, a piezoelectric vibrator is used.Problems to be solved by the inventionHowever, since the conveyor plate 1 has a finite length and it is difficult to match the acoustic impedance to vibration waves,
There was a problem in that the vibration waves were reflected at the ends of the conveyor plate l, generating standing waves as shown in FIG. 4, and the powder 3 remained at each meter point* of the standing waves. Point a in FIG. 4 is the position of the excitation means 2, and point b is the position of the support base 4.

とする。Means for Solving the Problems In order to solve the above technical problems, the conveying device according to the present invention has the following features:
It is characterized in that at least a pair of piezoelectric vibrators are coupled to the elastic conveying plate at intervals, one of these piezoelectric vibrators is used as an excitation vibrator, and the other piezoelectric vibrator is used as an absorption vibrator.
上述の構成に成る搬送装置において１弾性搬送板に結合

As a result, on the conveying plate, only a traveling wave is generated from the excitation piezoelectric vibrator toward the absorption piezoelectric vibrator, and no standing wave is generated. Therefore, no powder stagnation phenomenon occurs due to standing waves.

a piezoelectric vibrator coupled to its back side at one end side;
6 is a piezoelectric vibrator coupled to the other end side. These piezoelectric vibrators 5.6 have substantially the same characteristics and configuration, and are symmetrical. These piezoelectric vibrators 5.6 are coupled to the back side of the conveying plate 1 at the tip end surface of a receiving portion 51.61 formed in a blade shape. This embodiment shows an example in which the piezoelectric vibrator 5 is used for excitation and the piezoelectric vibrator 6 is used for absorption. A driving source 7 such as an oscillator is electrically connected to the excitation piezoelectric vibrator 5, and an absorption piezoelectric vibrator 6 is electrically connected to the excitation piezoelectric vibrator 5.
A load 8 such as an absorption resistor is connected to.

子６の位置である。When the excitation piezoelectric vibrator 5 is driven by the drive source 7 at an appropriate frequency, the vibration is transmitted from the receiving part 51 to the conveying plate 1, the conveying plate 1 is bent, and the vibration wave is transmitted to one end side of the conveying plate 1. The signal propagates toward the other end. The waves propagated from one end of the conveying plate 1 toward the other end are absorbed by the absorption piezoelectric vibrator 6 coupled to the other end. Therefore, on the conveying plate 1, only waves traveling in the direction of the arrow X from one end to the other end are generated, and the amplitude distribution of the conveying plate 1 varies depending on the position in the length direction, as shown in FIG. It remains constant without any fluctuation, and no standing waves are generated. Therefore, the powder 3 on the conveying plate 1 is smoothly conveyed in the direction of the arrow X from one end of the conveying plate 1 to the other end without causing a stagnation phenomenon due to standing waves. Note that point a in FIG. 2 is the position of the piezoelectric vibrator 5, and point b is the position of the piezoelectric vibrator 6.

とができる。Moreover, both piezoelectric vibrators 5 disposed on both ends of the conveying plate 10
．． 6 uses the same thing, so the conveyance system has symmetry. Therefore, contrary to the above embodiment, the powder 3 can be transported in the reverse direction Y by using the piezoelectric vibrator 5 for absorption and the piezoelectric vibrator 6 for excitation. Mutual switching between the piezoelectric vibrators 5 and 6 is easily performed by a switch etc. Effects of the Invention As described above, the conveyance device according to the present invention connects at least one pair of piezoelectric vibrators at an interval to an elastic conveyance plate. However, since one of these piezoelectric vibrators is used as an excitation vibrator and the other piezoelectric vibrator is used as an absorption vibrator, it is possible to collect powder without causing stagnation due to standing waves. It is possible to provide a conveying device that can reversibly convey the conveying plate from one end side to the other end side or from the other end side to the one end side.
