Abstract

PURPOSE:To stack and house a lot of parts and thereby aim at labor-saving in time of supplying, by extruding flat parts at a lowermost layer inside the plurally stacked magazine racks in a horizontal attitude one by one, while cutting it out after making each of them into a vertial attitude by means of a magnet inside a 90 deg. turning mechanism. CONSTITUTION:An extruding cylinder 17 of a feeder 10 extends to some extent whereby a lowermost one of flat cylindrical chaplets 23 being stacked in a horizontal attitude inside each of magazine racks 34a-34c is extruded to the inside of each of 90 deg. turning mechanisms 13a-13c by dint of extruding plates 15a- 15c, and in time of retracting these extruding plates 15a-15c, it is attracted to a permanent magnet 24 due to a difference in surface areas, coming to a vertical attitude upon being turned by 90 deg., and it is held on a guide surface 21. Next, a cutoff cylinder 18 extends to some extent whereby each of cutoff plate 16a-16c is thrust inside each of these 90 deg. turning mechanisms 13a-13c from a slit 25, depressing these chaplets 23 along each guide surface 21 and making them drop out of a cutoff port 26, and each chaplet 23 is fitted in a holding groove of a chaplet holder in a vertical attitude, thus it is held. Therefore, a lot of parts can be stacked and housed inside these racks and, what is more, labor and trouble for supplying are saved to the utmost.

Next, to explain the operation of this embodiment, when the cart 4 moves to a predetermined position and comes to rest, each mounting groove 70a
, 70b, 70c with flat cylindrical embossments 23 attached thereto, the upper die 6 is lowered onto the lower die 5, and a core having the flat cylindrical embossments 23 is molded. After that, the upper mold 6 rises and is released, and the lower mold 5
After the molded core is released and pushed up, it is taken out by the take-out device and transported to the next step, and while the take-out device is operating, the flat cylindrical keren 23 is attached to the upper mold 6. be exposed.

That is, in the supply bag W10, the extrusion cylinder 17
is operated to extend, and each magazine rack 34a.

The lowest layer of the flat cylindrical plates 23 stacked horizontally in the j4b and 34c is the extrusion plate 15a and 15.
90 degree rotation mechanism 13a, 1 jb by b, 15c
, 13c. Near the edge, flat cylindrical keren 2
3 is a 90 degree rotation mechanism 13a, 13b, 1 in a horizontal position.
3c, but the extrusion plates 15a, 15
Due to the difference in surface area during the backward movement of b, l 5 c, it is attracted to the permanent magnet 24, and is held on the guide surface 21 in a state of being turned 90 degrees and assuming a vertical posture.

Next, the cutting cylinder 18 is operated to extend, and the cutting plate 16a is
, 16b, 16c push into the respective 90-degree rotation mechanisms 13a, 13b, 13c through the slit 25, and push down each flat cylindrical part 23 along each guide surface 21.As a result, each flat cylindrical part 23 At this time, each holder 48a in the center device 11 falls downward from the cutting opening 26.

48b and 48c are corresponding 90 degree rotation mechanisms 13a.

13b, i3c are located below the cutting openings 26, and the flat cylindrical scraper 23 that has fallen is held in the holding grooves 65, 66 of the scraper holders 48a, 48b, and 48c in a vertical position. .

In this state, the horizontal movement cylinder 49 is extended, and the cleaning holder 61 is horizontally moved to just below the upper mold 6, and each cleaning holder 48a, 48b, 48c is attached 670a,
70 b, 70 c (7) directly below ift le.

Next, the extension operation of the lifting cylinder 5o is started, and the lifting cylinder 5o is moved to the base 61 and each lifting cylinder 48a.

48 b and 48 c rise, and the keren holder 48 a
.

Each of the flat cylindrical grooves 23 on 48b and 48c is connected to the mounting groove 7.
The mounting grooves 70a, 70b are inserted into the mounting grooves 0a, 70b, 70c with both ends protruding outward, and as the holder holders 48a, 48b, 48c are lowered.

70c, respectively.

The flat cylindrical parts 23 are held in the mounting grooves 70a, 70b, and 70c of the upper die 6, respectively, and the parting holders 48a, 48b are formed by the action of the cylinder 49.

When the lower mold 5 reaches a predetermined position and comes to rest at the stage when the lower mold 48c returns, the upper mold 6 starts lowering.

As a result, the upper mold 6 and the lower mold 5 cooperate to mold the core, but at this time, a flat cylindrical keren 23 is formed in the narrow part of the core.
Both ends of the core are buried, and as the upper mold 6 rises, the flat cylindrical part 23 remains in the core.

The core formed in this way forms a water jacket during casting of the four-cylinder cylinder block, and the flat cylindrical groove 23 functions to prevent deformation of the narrow part between each cylinder, and also serves to prevent the inside of the cylinder block from deforming. The water jackets formed around each cylinder are integrally cast into the cylinders to form water channels that communicate with each other between the cylinders.

According to this embodiment, the flat cylindrical part 23 is inserted into the upper mold 6 after the molding of the core is completed and before the water jacket core is taken out, so the time required for setting the flat cylindrical part 23 is There is no need to set extra, and the time in the core molding process can be shortened.

In the above embodiment, the flat cylindrical part 2 is used as the flat part.
Although the present invention has been described with reference to the case where a flat plate-like material is rotated by 90 degrees from a horizontal position to a vertical position, the present invention can also be implemented as an apparatus for supplying a flat plate-shaped object by rotating it by 90 degrees from a horizontal position to a vertical position.

C9 Effects of the Invention As described above, the device of the present invention includes a magazine holding mechanism that holds a magazine rack in which a plurality of flat parts made of magnetic metal are stacked in a horizontal position; an extrusion plate that extrudes the magazines one by one; a pair of guide blocks facing each other in front of the magazine rack holding mechanism;
A magnet is embedded in the vertical guide surface of one guide block, and a recess facing the guide surface that allows the flat part to rotate 90 degrees is provided in the other guide block. A 90 degree rotation mechanism is provided with a slit and a cutting opening in the upper and lower parts of the guide block; the guide block is driven up and down in order to be inserted into and removed from the 90 degree rotation mechanism through the slit and cut out a flat part from the cutting opening. Since it includes a cutting plate and;, a flat part in a horizontal position can be
It can be rotated several degrees and supplied in a vertical position. Therefore, a large number of flat parts can be stacked and stored in the magazine rack, and the trouble of replenishing them can be saved as much as possible. Moreover, the magnet is used to hold the flat part in a vertical position, and the flat part can be held with a simple structure.
