Recovery pallet 45 and recovery auxiliary pallet 55
Is normally connected via a fixing bracket 61, and the collection auxiliary pallet 55 can be taken out of the collection pallet 45 by releasing the fixing bracket 61 as necessary. The collection auxiliary pallet 55 is provided so as to operate in the same manner as the collection pallet 45 moves up and down. .

Since the elevating recovery pallet in the component transfer machine is constructed as described above, it is necessary to align the flat and thin part 62 or the flat and thin part 63 with the front and back as shown in FIG. Will be described.

In this example, a case where flat and thin components 62 are aligned will be described.

First, as shown in FIGS.
The pallet 6 is stopped in a horizontal state, and the lifting pallet 3 is stopped in a lowered state. In this state, a flat and thin part 62 is set on the collection auxiliary pallet 55 in the collection pallet 45. At this time, the collection auxiliary pallet 55 may be removed from the collection pallet 45 to perform the operation.

Next, the handle 35 of the pressing device 30 is pulled against the urging of the coil spring 36 to place an empty alignment pallet 2 on the table 6 and auxiliary pallets 26, 2 on both sides thereof.
7 and the handle 35 is released to release the empty alignment pallet 2 and the auxiliary pallets 26 and 27 from the table 6.
Fix on top.

In the above, when the operation of the motor 16 of the vibrating device 5 is controlled, the table 6 starts to vibrate at a preset amplitude and frequency, and is swingably mounted on the support plate 7. The table 6 is mounted on the collection pallet 4 when the support plate 7 swings through the swinging device 4.
The fifth side and the auxiliary pallet 26 alternately move up and down to start swinging.

When the table 6 starts to swing, the recovery pallet 55 inside the recovery pallet 45 and the recovery auxiliary pallet 55 inside the table 6 start to rise through the cylinder device 42, and can be taken out into the recovery pallet 45 as shown in FIG. 3b. It stops at the position where the bottom surface of the collected auxiliary pallet 55 and the surface of the auxiliary pallet 27 are flush with each other.

At this time, a flat and thin component 62 flows out from the collection auxiliary pallet 55 toward the alignment pallet 2, and about half of the components 62 fall into the component storage holes 65 provided in the alignment pallet 2 and are aligned. The rest is led to the auxiliary pallet 26 side.

When the swinging is reversed, the collection auxiliary pallet 55 inside the collection pallet 45 starts to descend, and the component 62 on the auxiliary pallet 26 side falls through the alignment pallet 2 to the collection auxiliary pallet 55. At this time, a part of the component 62 falls into the component storage hole 65 provided in the alignment pallet 2 and is aligned.

The components 62 can be aligned in the component storage holes 65 provided in the alignment pallet 2 by repeatedly performing the operation of simultaneously applying the vibration and the swing as described above.

In this example, a description has been given of a case where one type of component is aligned. However, the present invention is not limited to this. For example, a plurality of types of components may be aligned simultaneously.
Further, the collection pallet device 3 may be provided on both sides of the table 6.

[0032]

As described above, according to the lifting pallet in the component transfer machine according to the present invention, the recovery pallet is made up and down, so that many parts remaining after the alignment work can be removed from the pallet. And the parts do not protrude onto the alignment pallet.

Further, since a sufficient number of components for the alignment operation can be supplied to the alignment pallet, the alignment efficiency can be improved.

Further, a collection pallet which moves up and down in accordance with the swing of the alignment pallet is provided facing an end surface which moves up and down by the swing of the alignment pallet, and a contact portion between the collection pallet and the end surface of the alignment pallet is provided. By forming mutually continuous uneven portions in the longitudinal direction, and by providing these uneven portions so as to be slidable in a fitted state, when aligning flat and thin parts, the parts are arranged on the collection pallet and the alignment pallet. The collection pallet can be reliably moved up and down without being caught in the abutting portion with the end face, and the working efficiency can be improved.
