The transfer port and the transfer surface means consist of a plate 8 having upright flanges or walls 9.9'lL12 in the front, rear, left, and right directions, and an arm 13 that supports the plate 8 and rotates by cam means or the like (not shown). The front part of the dish 8 closely engages with the pin 3 for upward conveyance to the pin-type conveyance device, and has a cut groove 8' through which the pin 3 for upward conveyance passes from the bottom to the top. have.

Note that the plate 8 is located between the front flange on the plate 8 or between the wall 9 and q.
A gap corresponding to the gap of the cut groove 8' is provided.

The adjustment means E is located somewhat higher than the article transfer tray 8,
When the article A on the loading position 5 of the chute is pushed by a push button and placed on the tray 8, the arm 13 supporting the tray 8 pivots backwards by the action of a cam (not shown) and the tray 8 is placed on the tray 8. Push the upper item A′ forward with the adjusting plate to return it to its normal position.
That is, it serves to position it at the center of the cut groove 8' in the center of the front part.

This adjustment means E consists of a main body 14 having a V-shaped notch and a mechanism 15 for elastically pushing the main body 14 forward.

Finally, the insertion means F includes two rotatable rows 216, 16' mounted on the frame 1 across the conveying chain 2, and a rocker that supports these rows 216, 16' so that they can move up and down. It consists of movable arms 17, 17' and a stopper 18.

In this case, the rows 216.16' do not necessarily need to be rotatable, but only need to have smooth surfaces and less wear.

Further, it does not necessarily have to be a cylindrical roller, and may be a simple swash plate or a semicircular plate.

That is, the main configuration of the device according to the present invention is as follows.

A transfer plate 8 attached to the transfer plate horizontal swinging means extends from the vertical transfer section of the pin-type transfer device to near the attachment portion of the transfer pin 3.

The plate 8 has a cut groove 8' through which the conveying pin 3 passes.

There are insertion rollers 16, 16' above the plate 8, and the distance l from the top surface of the plate 8 to the outer diameter lower surface of the insertion rollers 16, 16'.
is approximately x~% of the outer diameter of the target article A.

The insertion rollers 16, 16' have their fulcrums on the frame 1 of the pin type conveyance device and can pivot in the vertical direction.

A stopper 18 is provided on the frame 1 to regulate the gap m between the maple frame 1 and the insertion rollers 16, 16' to approximately 1 to 1 of the width of the article.

Further, the insertion rollers 16, 16' are supported by bearings (not shown) so that they can rotate freely.

Guides 9, 9' are placed on the tray 8 so that the items are placed approximately in the center.
There are 11.12.

An adjustment plate 14 for determining the normal position of the article when the conveying pin 3 scoops the article from the tray 8 is held by a support shaft 20, and the support shaft 20 is guided by a guide 19.

The adjusting plate 14 is pushed forward by a spring 18'.

Next, the action will be explained.

When the article A is positioned on the loading position 5 of the shoe shoe B, the pusher C pushes the article A onto the transfer plate 8 which is attached to the flat transfer plate horizontal swinging means.

However, at this time, the article A is not always correctly positioned on the plate 8 in the state A.

Then, the arm 13 supporting the plate 8 is once pivoted rearward by the action of a horizontal swinging means such as a cam means (not shown).

Behind the plate 8 is an adjustment plate 1 located slightly higher than the plate 8.
4 is fixed, and the article A hits the V-shaped notch of this adjusting plate 14 and is pushed relatively forward, and the 7-shaped guides 9,
9', the article is normally positioned on the tray 8 in the state shown in FIG.

At this time, if the outer diameter of the article is large, the adjustment plate 14 will move backward, but if the plate 8 moves forward again, the spring 18'
is pushed back to its original position.

Next, the plate 8 is moved forward by the arm 13 by the action of a cam or the like, and is positioned in a position opposite to the conveying chain 2 of the vertical frame 1 standing upright in front of it.

At this time, the cut groove 8 of the plate 8 is in a position facing the upward conveyance pin 30 carried by the conveyance chain 2.

Upward conveyance pin 3 carried by conveyance chain 2
Since the pin 3 is set to pass through the cut and groove of the plate 8, the article 1 is scooped up and held on the plate 8 by the pin 3 and moved upward.

At this time, insertion rollers 16° and 16' are fixed to the frame 1 and straddle the conveying chain 2 at a position above the plate 8 with a predetermined gap therebetween.

Therefore, when the article A scooped up from the top of the tray 8 by the upward conveyance pin 3 passes under the insertion rollers 16, 16', it is sufficiently pushed to the base of the upward conveyance pin 3. It is carried upward by pin 3.

The plate 8 is returned to its original position by the arm 13 under the action of a cam.

As explained above, the present invention provides a chain running endlessly within the frame along a conveyor frame having an arbitrary shape, with pins spaced at predetermined intervals and with the tip protruding from the frame. An article transfer device of a pin-type conveying device that conveys an article with a large number of pins attached and the tips of each pitch inserted and locked in a through hole of the article, the article being closely opposed to the frame of the vertical running part of the pin. A swinging arm is provided with a cut groove in the center of the front part of the frame side through which the pin can pass, and receives the article pushed out from the loading position on the chute in an overturning position, and horizontally approaches and moves away from the frame. A transfer unit is attached to the transfer unit, and the tip is fixed at the rear of the transfer unit, and when the transfer unit swings backward, the tip touches the article on the transfer tray.
an adjustment member having a V-shaped notch in contact with which the position is adjusted to the center position of the cut groove of the transfer section; It is equipped with an article insertion roller that straddles the travel path of the pin and pushes the article into the frame when it passes from the transfer section to the article being held by the pin. It is possible to very easily transfer the incoming articles onto the conveying pins that move the vertical frame upward.

Further, the positional relationship of each part is extremely flexible in response to changes in the shape and dimensions of the article, and no adjustment is required if the shape or dimensions change to some extent.

Furthermore, the structure is simple, has great manufacturing advantages, and is naturally inexpensive.
