Description

[Detailed description of the invention] This invention is used for an array mold for press molding.
This invention relates to a magnetic conveyance device for products, etc. between molds.

Conventionally, an air cup has been used in an array type product conveying jig or device, but the position of the cup attached to a support rod and the support rod mounting portion are far apart. When trying to hold the cup against the product and try to make it stick, the support rod becomes distorted and the product doesn't stick well, so the height of the support rod has to be adjusted, which greatly impairs work efficiency. was. Another problem was that after using the cup for a certain period of time, the cup cracked and the suction became poor, so it had to be replaced periodically. Furthermore, air is consumed even in processes where there is no product to be adsorbed.

Additionally, there are apparatuses for supplying pressing materials as shown in Japanese Patent Publication No. 51-36503 and Japanese Patent Publication No. 51-36919.

The inventions disclosed in these publications have a structure in which a press material is attracted using a magnet and is transported above the material placement position of the lower press die. However, the device of the present invention attracts one press material with a magnet and manually moves it to the material placement position of one press lower die.
The magnet is moved by the movement of the material supply rod in the axial direction, and the magnet is moved through a plurality of means using a swinging lever, so there are problems such as a complicated structure.

The present invention uses magnets to convey products or materials, and uses wires to simultaneously operate multiple magnets placed above multiple supply points for products or materials. By attaching each to multiple support rods and moving the multiple support rods simultaneously, it is possible to simultaneously transport products or materials attracted to the magnet, which solves the problems of the conventional method. This is an attempt to solve the problem. Furthermore, the present invention includes a wire lever so that the wire for operating the magnet can be moved in conjunction with the movement of the plurality of support rods, and a cam means for operating the lever.

Embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a support rod extending substantially horizontally and having three branch rods. A wire receiver 2 is provided below each branch rod of the support rod 1.

The structure around the wire receiver 2 is as shown in FIGS. 2 to 4, and the wire receiver 2 has a through hole 2' for slidably guiding the wire 5 and a hole 2 for housing the spring. ′. A coil spring 4 is housed in this hole 2'' so as to surround the wire 5, and one end of the coil spring 4 comes into contact with a slide stopper 6 fixed to the wire 5 to move it in one direction ( (in the right direction of the arrow in Fig. 2).

A plate 7 is fixed to the lower side of the support rod 1, and the upper surface of a plate cam 8 fastened to the wire 5 is in contact with the flat lower surface of the plate 7.

The magnet holding shaft 9 is fitted into a case 10, and its upper end is fixed to a recess of the plate 7 by a circlip 11 and extends downward, and a magnet 12 is held in the recess at its lower end.

A coil spring 13 is interposed between the stepped portion of the magnet holding shaft 9 and the stepped portion of the case 10.
0 is constantly applied to the cam surface of the plate cam 8. The magnet holding shaft 9 has a through hole 14 elongated in the axial direction.
The plate cam 8 is loosely inserted into the through hole 14.

The plate cam 8 has a flat upper surface for sliding in contact with the lower surface of the plate 7, and has a through hole 5' through which the wire 5 is inserted. It is located below the hole 5'.

The wire 5 extends below and substantially parallel to each branch of the support rod 1, as shown in FIG.
One end thereof is locked to the wire receiver 2 as described above, and the other end is locked to the wire shaft 20.

As shown in FIG. 1, at the other end of the wire 5, there is shown a mechanism for reciprocating the wire and a mechanism for causing the support rod 1 to move horizontally and move up and down.

The reciprocating mechanism of the wire will be explained. A wire lever 21 is pivotally attached to the side surface of a substantially horizontal support plate 22 integrally fixed to the support rod 1 by a support pin 23 so as to be able to swing within a substantially vertical plane. The wire shaft 20 is fixed to the tip of the arm above the support pin 23 of the wire lever 21, and the other end of the wire is locked to this. A protrusion 24 fixed to the upper surface of the support plate 22 and protruding laterally and a wire shaft 20
A tension spring 25 is tensioned between the wire lever 21 and the wire lever 21, and constantly biases the wire lever 21 in the counterclockwise direction.

A cam roller 26 is rotatably provided at the tip of the arm of the wire lever 21 below the support pin 23. The magnetizing cam 27 is solidified on the substrate of the transport jig main body frame 28, and is attached to the support rod 1.
The wire lever 21 is lowered by the downward movement of
The wire lever 21 engages with the cam roller 26.
It has a cam surface 27' adapted to rock.

Next, a mechanism for horizontally and vertically moving the support rod 1 will be explained.

The transport jig body frame 28 includes a horizontal substrate 30 extending in the direction of horizontal movement of the support rod 1, side plates 31 extending vertically upward from both ends of the substrate 30, and a guide shaft connecting the tops of the side plates 31, 31. 3
2 and a guide plate 33.

The conveyance cam 34 fixed on the substrate 30 has a horizontal cam surface 34a that guides the horizontal movement of the support rod 1;
It consists of cam surfaces 34b and 34c that guide upward and downward movements.

The cam roller 35 is connected to the upper surface 34 of the conveyance cam 34.
a, and is pivoted on a cam roller base 36.

The slide shaft 37 integrally connects the cam roller base 36 and the support plate 22 located directly above it. Therefore, the support rod 1, the support plate 22, the slide shaft 37, the cam roller base 36, the wire lever 21, the cam roller 35, and the wire shaft 20 all move integrally and simultaneously.

The slide bush 38 is the slide shaft 3
It is slidably fitted to the outer periphery of the slide shaft 37 so as to be movable relative to the slide shaft 37 .
The guide bush 39 is slidably fitted onto the guide shaft 32, integrally coupled with the slide bush 38, and pivotally supports a guide roller 40 adapted to roll against the side surface of the guide plate 33. . The coil spring 41 is attached to the support plate 22
is provided surrounding the slide shaft 37 between the slide bush 38 and the slide bush 38.
8, the support plate 22 is urged upward. A handle 42 is fixed to the cam roller base 36.

The protrusion 43 formed upward from the conveyance cam 34 is used to determine the standby position to prevent the support rod 1 from being damaged by the mold. This position is then confirmed with a limit switch (not shown) to prevent the press machine from operating.

5 to 7 show a mechanism for supplying the material 45 to the mold 46. As shown in FIG. In the material supply device 50, a plate 52 pushed up by a spring 51 is guided by a guide bar 53. In order to transport the material 45 to a predetermined position in the mold 46, a positioning pin 54 is implanted that passes through the plate 52 and has a stopper 55 in the middle.

In order to prevent a plurality of raw materials 70 from being fed together due to oil adhesion, etc., a magnetic separator 56 is installed in close contact with the side surface of the raw material 45.

Next, the effect will be explained. Holding the handle 42 in your hand, move the cam roller base 36 to the right in FIG.
2 and the supporting rod 1 integrated therewith are lowered. In this position, the wire lever 21 does not swing, so
The wire 5 also does not move, and the magnetic case 5 is kept in the raised position as shown in FIG. 3, and when the magnet 12 approaches a product or material, it instantly attracts it.

Next, while holding the product 15 or material 45, hold the handle 42 and move the support rod 1 to the left in FIG. When the cam roller 35 is guided, the support plate 22 descends, and as the support plate 22 descends, the cam roller 26 attached to the wire lever 21 moves towards the magnetizing cam 27.
Since the wire lever 21 is guided by the cam surface 27' of the wire lever 21, the wire lever 21 swings in the direction of the arrow (clockwise) in FIG.
The wire shaft 20 fixed to the upper end of the wire shaft 20 and the wire 5 locked thereto move in the direction of the arrow.

As a result, the plate cam 8 moves in the opposite direction to the arrow in FIG. 2 against the force of the coil spring 4 and the spring 13, pushing up the magnet case 10 as shown in FIG. The product 15 or material 45 that has been attracted to the lower end surface of the net case 10 is separated from the magnet 12 and dropped onto the mold. Then return it to its original position.

Since the present invention has the above-mentioned structure and function, the magnet has the effect of instantaneously magnetizing the product, and at the same time, even if multiple magnets are used in one product, the magnet case can be lowered at the same time to remove the magnets. Since the product is dropped from the machine, it not only ensures the positioning of the product, but also reduces noise and saves energy. In addition, the plurality of conveying cams that act on the magnets attached to the support rods are each connected to a wire, and one end of each wire is connected to a wire lever, so by bringing the wire lever into contact with the magnetizing cam, Multiple magnets operate simultaneously, and multiple products can be transported simultaneously, making it extremely efficient.

In the embodiment shown in FIG. 5, the work efficiency can be greatly improved since the material supply and the product transport are performed simultaneously, compared to the conventional manual material supply method. Furthermore, since air and electricity are not used, there is no need to change the setup of external wiring or piping.

It can be used not only as an array-type conveyance jig, but also as a jig for press-molded product take-out devices and material supply devices, ensuring reliable take-out and supply.
