2. Description of the Related Art When molding a rubber product with a metal fitting, for example, when molding it with an injection molding machine, generally, a large number of metal fittings are stocked in a space adjacent to the injection molding machine. After that, the metal fittings required for one injection molding are set in the mold of the injection molding machine and injection molding is performed.

When the metal fittings have a tubular shape, for example, a cylindrical shape and have a brim at one end, the metal fittings are stocked by holding them in a stacking state. It is convenient to take out the top metal fittings one after another.

However, this type of tubular metal fitting with a collar is usually manufactured by drawing, and in this case, the inner surface of the portion from the tubular portion of the main body to the collar is curved,
For this reason, when these metal fittings are stocked in a stacked state by aligning the directions, the tip of the main body tubular portion of the adjacent metal fitting is partially fitted into the curved shape portion, that is, the upper and lower metal fittings bite each other. It will be in a state.

Therefore, when the metal fittings are sequentially taken out from the uppermost stage by the chuck, there is a problem that this cannot be done smoothly. Such a phenomenon also occurs when the inner surface shape from the main body cylindrical portion to the flange is tapered.

As a method for solving this problem, metal fittings are not stacked and stocked, but instead, as shown in FIG.
As shown in FIG. 6A, a method of stocking a large number of metal fittings 100 one by one on a plane, or FIG.
As shown in (B), a chuck having a separation claw 102 at its tip is used as a chuck for sequentially taking out the metal fittings 100 that are stacked in a stacked state from the uppermost stage, and these are opened and closed. A method of taking out the metal fitting 100 can be considered.

However, in the former case, there is a problem that a large space is required for stocking the metal fittings, and in the latter method, the form of the chuck and the holding posture of the metal fitting 100 by the chuck are limited, and the post process There is a problem that interferes with the work in.

[0008]

The device of the present invention has been devised to solve such problems, and its gist is that it has a tubular shape as a whole and is provided with a collar on one end side. A stock / separation device for flanged metal fittings that stocks tubular metal fittings with a collar in a stacked state and separates the metal fittings that bite from each other. A holding rod for holding in a stacked state and in a direction aligned with each other, and (B) a plate-shaped member that is provided so as to be slidable, and (a) allows the metal fitting to pass through at a predetermined position in the axial direction. And a metal fitting passage recess that is large enough for
(B) A metal fitting insertion recess that is provided subsequent to the metal fitting passing recess and into which the main body cylinder portion of the metal fitting is inserted, and (c) a separation claw provided at an edge of the metal fitting insertion recess, Further, the separation claw is provided at a position to enter between the flanges of the metal fittings vertically adjacent to each other during sliding movement and to apply a force in a separating direction to the flanges,
(C) a position where the metal fitting passes through the metal fitting passage recess,
A drive mechanism for slidingly moving the claw plate between the separation claw and a position where the separation claw enters between the collar and the collar;
(D) A lifter for sequentially feeding the metal fittings fitted to the holding rods and held in a stacked state upwardly for each reciprocating movement of the pawl plate.

[0009]

In the device of the present invention, a large number of metal fittings are fitted to the holding rod, and the pawl plate is slid by the drive mechanism while being held in a stack.

At this time, the main body tubular portion of the metal fitting is inserted into the metal fitting insertion recess of the claw plate, and the separating claw provided at the edge of the metal fitting insertion recess is inserted between the flanges of the upper and lower metal fittings. , Apply a force in the pulling direction to them. As a result, even if the upper and lower metal fittings are bite, they are separated well.

In the present invention, if the device is set so that the uppermost metal fitting and the lower metal fitting are separated,
After separating the uppermost bracket, it can be taken out immediately with a predetermined chuck, and then with the pawl plate returned to its original position, the lifter sent out the stacked brackets for one pitch upward and again as above. By performing the same operation, it is possible to separate the metal fitting newly located on the uppermost stage from the metal fitting on the next stage.

As described above, according to the apparatus of the present invention, the metal fitting to be supplied next can be surely separated from other metal fittings, and therefore the metal fitting can be smoothly taken out by the chuck. Moreover, since a large number of metal fittings can be stocked in a stacked state, there is an advantage that the space for stocking is small.

A rack is engraved on a center shaft 18 extending from the center of the rear surface of the lifter 16. The lifter 16 can be moved up and down by a rack and a pinion that meshes with the rack and a motor that rotationally drives the rack.

Reference numeral 20 denotes a holding rod provided in a fixed position, and a large number of metal fittings 10 are fitted to the holding rod 20 in a state in which the directions are aligned and are held (stocked) in a stacked state. The bottom metal fitting 10 is a lifter 16
The lifter 16 is movable relative to the holding rod 20.

Reference numeral 22 denotes a column, which is attached to the support member 23 via a mounting member 25 in an upright state. The horizontal guide mechanism 2 is provided on the upper end of the column 22.
4 is provided, and the claw plate 26 is provided so as to be slidable in the horizontal direction via the guide mechanism 24.

The claw plate 26 is provided with a downwardly directed arm 28 at the right end in FIG. 2, and this arm 28 is connected to a slide drive cylinder 30 fixedly mounted on the column 22. As shown in FIG. 1, the claw plate 26 has a form in which a first plate 32 and a second plate 34 are connected to each other by a bar 36.

The claw plate 26 is provided with a total of four substantially first circular recesses (metal fitting passage recesses) 38 having a size sufficient to allow the metal fitting 10 to pass therethrough. A second recess (metal fitting insertion recess) 40 into which the main body cylindrical portion 12 of the metal fitting 10 can be inserted is provided continuously in the direction. Then, a total of four sets of separation claws 42 are attached to the edge portions of these second recesses 40 so as to face each other. Each separation claw 42 has a wedge-shaped acting portion 44 (see FIG. 4) at the upper end in FIG. 1 (right end in FIG. 2).

The spacing between the inner ends of the separation claws 42 of each set provided so as to face each other is wider than the outer diameter of the main body tubular portion 12 of the metal fitting 10. Also claw plate 2

Next, the operation of this apparatus will be described. In this device, the first recess 38 of the claw plate 26 is initially positioned at a position corresponding to the holding rod 20 (see FIG. 4 (I)), and the uppermost metal fitting 10 passes through the first recess 38. And is located slightly above it. At this time, the separation claw 42 is located at a position retracted from the metal fitting 10 to the left side in FIG. 2 and FIG. 4 (lower side in FIG. 1).

From this state, the claw plate 26 is first moved to the right in FIG. 2 (upward in FIG. 1) by a constant stroke. At this time, the main body cylindrical portion 12 of the metal fitting 10 in the next stage is inserted into the first recess 38 of the pawl plate 26, and at the same time, the separation pawl 42 attached to the edge of the second recess 40 is shown in FIG.
As shown in (II), the metal fitting 14 of the uppermost stage and the collar 14 of the next-stage metal fitting 10 are cracked and inserted, and at this time, in the wedge-shaped action portion 44 at the tip end, they are separated from each other. Apply force. Therefore, even if the top metal fitting 10
Even if the metal fitting 10 at the next stage and the metal fitting 10 at the next stage are in a bite state with each other, these can be favorably separated vertically.

The uppermost metal fitting 1 separated in this way
0 is held by a predetermined chuck and then carried to the mold side of the injection molding machine and set there.

On the other hand, the claw plate 26 that has slid a predetermined stroke in the right direction in FIG. 2 is returned to the original position in the left direction in FIG. 2, and the first recess 38 is again stacked.
It is located at the position corresponding to 0.

After that, the lifter 16 operates to feed the stacked metal fitting 10 upward by one pitch. At this time, the uppermost metal fitting 10 passes through the first recess 38 of the claw plate 26 and projects upward.

Then, the claw plate 26 is again slid to the right in FIG. 2, whereby the metal fitting 10 newly located at the uppermost stage is separated from the metal fitting 10 at the next stage. The same operation is repeated thereafter.

As described above, according to the apparatus of this embodiment, even if the metal fittings 10 in the stacked state are in a bite state, the metal fittings 10 in the uppermost stage are reliably separated from each other. Therefore, it is possible to smoothly take out by the chuck. Further, according to the present device, since a large number of metal fittings 10 can be stacked vertically and stocked, the space required for stocking can be reduced.
