Was.

In the transfer device using the chuck shown in FIG. 5, the transfer speed of the pallet 3 is
The speed is relatively high because of the clamping, but before and after the transfer operation, the chuck front-back operation, the chuck opening / closing operation, and the chuck up / down operation are always required, and the overall transfer time becomes longer, resulting in poor productivity. Had.

Therefore, an object of the present invention is to obtain high productivity.

Has the effect of being able to.

According to a second aspect of the present invention, there is provided the transport apparatus according to the first aspect, wherein the pallet is movable in the vertical direction with respect to the transport belt. It has the effect of improving productivity.

According to a third aspect of the present invention, there is provided the transport apparatus according to the first or second aspect, wherein the transport belt has magnets built therein at predetermined intervals, and a tape having a high friction coefficient is fixed to a surface that contacts the pallet. In addition to the effects of the first and second aspects, the present invention has the effect that the transport speed can be further increased.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 3 denotes a plate-like pallet for stacking and mounting sheets 2 such as a magnetic substance and a dielectric substance to form a laminated body 1 constituting an electronic component. , For example, an iron-based magnetic material.

One end of the pallet 3 has a plurality of cylindrical magnets 28 built therein at regular intervals, and is mounted on a conveyor belt 27 having a toothed surface on one side.
Then, the pallet 3 is moved and conveyed by the pair of conveying belts 26 which are synchronously moved while meshing with the toothed pulley 29 which is rotationally driven by the driving motor 20.

Reference numeral 24 denotes a stage, which is a transfer belt 26,
