The tip of the support part 0◇ of a) is located on the outside of the insertion part 6''h of the roller conveyor m, the alignment plates on both sides are located on the outside of the roller conveyor, and the stopper plate (c)
It is assumed that the roller conveyor (a) is waiting at the front of the fixed stopper of the roller conveyor (a).

Then, one sheet of 81/piece Φ) is supplied from the storage frame (101) of the z4'let supply device (9) onto the base end of the chain conveyor, and this 411/piece (P) is fed to the base end of the chain conveyor. It is transported to the loading position (2) by the loader, and serves as a stopper in the raised state, and the 1/t support stand (in the raised state)
b)), and then move the %l/nt support support platform up t, te/set]/soto ψ) to the chain conveyor (toward).
Lift it up and make sure that the top surface of the (about 1/t) is aligned (
1) Roller conveyor... to a position that is approximately at the same height as the upper end of the fixed stone eta? +/sotoψ).

Note that when /4' I/knot P) is lifted, the stopper wheel of the conveyor (2) is moved downward and retracted.

In this state, when the articles (c) are sequentially fed onto the base end of the roller conveyor, the articles (c) are conveyed to the tip of the roller conveyor and stopped at the tip. Then, the succeeding goods are stopped by the preceding goods (c) or by intermediate spacers (2) which are lowered as necessary during the loading turn.

It is assumed that the articles (c) are sequentially supplied in a state in which they are oriented in a predetermined collision direction in accordance with the loading pattern.

In this way, when a predetermined number of items (6) for one row of the loading turn are arranged at the tip of the roller conveyor, the separation stone /4'f rises and the items (6) for one row are collected. At the same time, the transfer mechanism VO is activated and its V bell) (7G rises and rotates, and the items (c) in one row are placed in the alignment position (1). It is transferred to a roller conveyor (7) and stopped at a fixed stopper (to) at its tip.

In addition, when one row of items) is transferred from the tip of the roller conveyor to the roller conveyor, the V-pel of the transfer mechanism H) (712 descends and the ■ belt (7G
The rotation of the separation stopper ql is stopped, and the separation stopper ql is moved downward and retracted, and the intermediate spacer 171 is moved upward and retracted by -1 if it had been lowered.

In this way, when the predetermined row of items (E) for one stage of the loading pattern are arranged on the roller conveyor at the alignment position (1), both of the holding devices (Iflj's fork body ■ and the alignment plate) closes, the locking rod (C) lowers, and as a result, one stage of goods (E) is moved to the fixed stopper (G) of the roller conveyor group and the locking rod (H) of the holding device (E). ) and alignment plates on both sides) to align from the front, back, left and right, and also on the fork bodies on both sides of the holding device (a))
The support part 01) of the roller conveyor (the side frame 6 of A) is inserted between the roller trowels through the force of the insertion part G between the roller conveyors (the side frames 6 of A), and is inserted below the one stage of articles).

Next, the elevating frame (5) rises, the support part 0]) of the fork body (A) immediately lifts up one stage of goods (5), and the force G of the support part reaches the stopper of the roller conveyor Φ). If the goods (e) are loaded at a position slightly higher than the height ψ) (if the goods (e) are already loaded at the stopper), and the loaded goods ■ rise to a position 11) slightly higher than the , when the lifting frame (5) stops rising, both
The horizontal movement frame (7) moves to the loading position (2) and transfers the held items (G) to the stack of 1/tΦ) (or the already loaded items (E)). Move upward and position the held item (support) for one stage on the IK of the first knot (P) (or the item already loaded).

Note that when the horizontal movement frame (7) moves and stops, the article (G) tends to shift forward due to inertia, but since it is stopped by the stopper plate (C), this shift can be almost eliminated.

Then, the lower locking pieces (c) on both sides descend to come into contact with both sides of the 91/tsut Φ) (or both sides of the already loaded item (2)).

In addition, when loading all the items (1) on the first tier, the lower tier locking piece (c) does not necessarily need to be lowered.

Then, the fork bodies on both sides) open and one layer of items (
g) f /4' l/soto ψ) (or onto the already loaded items (c)), and at the same time raise and retract the stopper plate (c) and the locking rod).

In addition, when the fork body (2) opens, since the joint part C32 is provided in the support part 0υ, the support part 0])
Fold along the small gap between the item (C) that was being supported and the item (C) that was being supported (or between the item that was being supported (C) and the item that has already been loaded). By doing this, the falling distance of the item (G) can be extremely reduced, and at this time, the supporting part 0]) is bent over the supported item (G) and 1/SotoΦ) (or The already loaded items (a)) are scraped, but the items W that were being supported are positioned by the alignment plate -, and...
Since the item Φ) (or the already loaded item) is positioned by the lower locking piece (c), the loading condition will not be disturbed.

Then, as the alignment plate 4 opens, the lower locking piece 4 moves upward and retreats.

Next, the horizontal movement frame (7) moves to the alignment position If (1), and then the elevating frame (5) lowers and the stopper plate N lowers to return to the standby state.

Also, when the alignment plate (to) opens and the lower locking piece 2 rises and retreats, the 1st knot support platform lowers by the height of 1 tier of items (c), and the load is placed in the 1st knot ψ). Stacked items (g)
The upper surface is approximately at the same height as the upper end of the fixed stone 9 (4) of the roller conveyor (1) at the alignment position (1).

In this way, one holding device (a) sequentially holds one stage of items (
c) Transfer from the roller conveyor wall at the full alignment position (1) to the loading position (2nd 1,000 knots (P)) and use the Pa 1 knot support (-f l/nod ψ). Lower the item by the height of one step of the item (5), and the item) will pop)
When the load is loaded onto (P) at a predetermined turn, the chillet support platform et41 is lowered below the chain conveyor ■, and the 1/t (P) is supported by the chain conveyor wheels.
Thereafter, the paper is conveyed by a roller conveyor ([)] and stopped by a fixed stopper [theta].

In addition, when the 1,000 knots (P) are conveyed to the roller conveyor (A), the chain conveyor's height rises.

Then, it is carried out by a half-oak lift or the like on a chain conveyor.

In this embodiment, the raising and lowering of the holding device) is performed only at the alignment position (1), but if it takes time to raise and lower the knot support stand H, the raising and lowering of the knot support stand In order to shorten the stroke length, the holding device (2) holding the goods (G) may be raised and lowered relative to the pallets (P/T) and CP) when loading items several levels below. .

〔Effect of the invention〕

As described above, according to the present invention, in the pa-knot loading device, the scooping opening/closing body for holding the goods is pivoted so that it can be fully opened and closed, so a large space is not required for opening/closing the opening/closing body. In addition, a roller conveyor is provided at the position where the items are lined up, and an insertion section is provided between the trap rollers on both sides of the roller conveyor, so when scooping up items, you can simply close the opening/closing body to support the opening/closing body. The product can be inserted between the rollers through the insertion part, and the product can be immediately picked up by simply raising the lifting frame.Therefore, there is no need to lift the product, and the product can be easily held. A joint part is provided in the support part of the opening/closing body, and the tip side of this joint part is formed so that it can be bent only upward.
When pulling out the support part of the opening/closing body from the bottom of the item, the support part bends along the bottom side of the item, so there is no need to worry about the tip of the support part hitting the lower part or the item. There is no
The falling distance of the item can be shortened, eliminating damage to the item.

Then, at the loading position,
Since the lifting frame can be raised and lowered by as much as 100 kg, the lifting distance of the lifting frame can be shortened, and the loading capacity can therefore be improved.
