BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a workpiece material conveying apparatus, and in particular, to a workpiece material conveying apparatus suitable for sending a press secondary processed material for the next press working process.

When there is a distance between the withdrawal end point of the processing material drawn out by the drawing device from the pressing machine of the preceding process and the starting point of supply of the processing material supplied by the feeding device to the press machine of the subsequent process, a conveying device such as a conveyor is used. is average. Moreover, when it is necessary to invert 180 degree and send a process material, the inversion apparatus is used. Conventionally, when conveying a processing material as it is without inversion, when installing a normal conveying apparatus and inverting and conveying a processing material, the inversion apparatus was reinstalled instead of the normal conveying apparatus. Therefore, in one press working line, switching installation work is cumbersome and time-consuming when non-inverting conveyance and reverse conveyance are often switched.

An object of the present invention is to solve the above-mentioned problems and to provide a workpiece material conveying apparatus which can easily switch non-inverting conveyance and reverse conveyance by an object of a jig.

In order to achieve this object, the present invention rotatably connects the inner end of the first rotating arm and the inner end of the second rotating arm to move the outer end of the first rotating arm and the second rotating arm only in the horizontal direction. Two reverse jig, first horizontal moving member and second horizontal support which are rotatably supported by the first horizontal moving member and the second horizontal moving member, respectively, and detachably mounted to the first rotating arm and the second rotating arm, respectively. The movable member is provided with two movable jig which are detachably attached to each of the movable members, and is equipped with an adsorber for adsorbing jig-shaped workpieces on each jig, and the first rotary arm and the second rotary arm are moved to the horizontal position when they are inoperative. During operation, the connected inner end is lowered from one jig to the other position where the processing material is passed to the other jig, and the driving force is transmitted back to the horizontal position. A stage is formed, whereby in the case of inversion conveyance, by using the inversion jig, the first rotational arm and the second rotational arm are rotated downward by 90 degrees and in one direction from the inverted jig at the vertical position. The processing material is transferred to the other reversing jig by inverting the processing material by 180 degrees. In the case of non-inverting conveying, the moving jig is used to be smaller than 90 degrees of the first rotating arm and the second rotating arm. It is characterized by moving a processing material by the number of the processing materials from one movement jig | tool to the other movement jig | tool in the rotation below and a reverse rotation and an approach position of a predetermined angle.

Next, the present invention will be described in detail by way of examples.

1 to 3 show a state in which the reversing jig or the moving jig for holding the work material is released. The main body 1 is processed to the bowler etc. of a press. The drive shaft 2 connected to a power source such as a crankshaft of the press is rotatably supported by the bearing 3 in the main body 1, and the tip thereof protrudes from the main body 1. A driven shaft 4 is formed parallel to the drive shaft 2 and the driving force is transmitted by the gears 5, 6. A rack gear 7 meshes with the gear 6, and the rack gear 7 is connected to a lot of the air cylinder 8. The air cylinder 8 serves as a return spring.

A horizontal guide rail 9 is fixed to the main body 1, and rollers 12 and 13 of the first horizontal moving member 10 and the second horizontal moving member 11 are fixed to the guide rail 9. Fit it so that it can be driven. As a result, the first horizontal moving member 10 and the second horizontal moving member 11 are guided to be movable only in the horizontal direction. The brakes 14 and 15 are fixed to the first horizontal moving member 10 and the second horizontal moving member 11, and the brake drums 16 and 17 have the brakes 14 and 15 embedded therein. Contact with friction. Pins 18 and 19 are fixed to the brake drums 16 and 17. As a result, the pins 18 and 19 are not normally rotated and are fixed to the first and second horizontal moving members 10 and 11, but a predetermined or more rotational force is applied to the pins 18 and 19 from the outside. When the brake is caught, a flow occurs between the brakes 14 and 15 and the brake drums 16 and 17 so that the pins 18 and 19 rotate.

By the pin 18, the outer end 20a of the first rotating arm 20 is rotatably supported. Similarly, the outer end 21a of the second rotating arm 21 is rotatably supported by the pin 19. The inner end 20b of the first rotating arm 20 and the inner end 21b of the second rotating arm 21 are rotatably connected by a link 22 and pins 23, 24.

The inner ends of the links 25 and 26 are fixed to the distal ends of the driven shaft 4 and the drive shaft 2 which protrude forward from the main body 1, and the outer ends of the links 25 and 26, respectively. The pins 27 and 28 are respectively fixed to the pins 27. The pins 27 are rotatably connected to the center portion of the first rotating arm 20, and the pins 28 are connected to the center portion of the second rotating arm 21. Concave portions 29 and 30 on which the reverse jig (described later) are mounted are formed on the first rotating arm 20 and the second rotating arm 21. The recessed portions 29 and ( 30 has screw holes 31 and 32. The tip ends of the pins 18 and 19 are the mounting portions 33 and 34 to which the movable jig (described later) is mounted, and the screw holes are provided. It has (35) and (36).

4 shows a state in which the reverse jig 37, 38 is mounted. The reversing jig 37, 38 is a quadrangular frame and is fixed to the recesses 29, 30 by screws 39, 40 (FIG. 6). The first and second adsorbers 42 and 43 for holding the workpiece 41 by vacuum adsorption are mounted to the reversing jig 37 and 38 by the holders 44 and 45. . 46 and 47 are mounted in a releasable manner as guide pins for positioning the work material 41.

Since the shape of the image is flat, the screws 50 and 51 are fixed to the mounting portions 33 and 34 of the pins 18 and 19. Like the reverse jig 37, 38, the first adsorber 52, the second adsorber 53, the holders 54, 55, the guide pins 56, 57 are provided. The position of the processing material 41 in the horizontal position is the same position as that of the reverse jig 37, 38.

First, the reverse conveyance operation will be described with reference to FIGS. 6 to 8. At non-parallel, the links 25 and 26 are in the horizontal position shown in FIG. 6, whereby the first and second rotating arms 20 and 21 rotate in the horizontal position on the same horizontal plane. have. When the arm of the drawing device (not shown) draws out and transports the processing material 41 from the press machine and places it on the reverse jig 37, the first adsorption device 42 starts the adsorption operation under the control of the control device (not shown). Thus, the processing material 41 is held. At the same time, the drive shaft 2 rotates in the clockwise direction of FIG. 6, and accordingly, the driven shaft 4 rotates in the counterclockwise direction. Thus, as shown in FIG. 7, the links 25 and 26 rotate in opposite directions to each other while the first rotating arm 20 moves the first and second horizontal moving members 10 and 11 inward. ) And the inner end portions 20b and 21b connected by the second rotating arm 21 are cut. When the drive shaft 2 rotates by 90 degrees, the first rotating arm 20 and the second rotating arm 21 reach the vertical position shown in FIG. 8 and are in an overlapped state. Here, the clockwise rotation of the drive shaft 2 is stopped.

When the fact of reaching the vertical position is detected by a sensor such as a limit switch (not shown), the first adsorber 42 releases the adsorption of the processing material 41, and at the same time, the second adsorption 43 is made of the processing material ( 41). Therefore, the processing material 41 passes from the reversing jig 37 to the reversing jig 38.

Since the drive shaft 2 rotates 90 degrees counterclockwise from the vertical outer teeth shown in FIG. 8, the first and second rotary arms 20, 21 return to the soup outer tooth of FIG. 6 via the position of FIG. do. Thereby, the processing material 41 stops in the state reversed by 180 degrees at the position shown by the 2-dot dotted line in FIG. At this position, the second adsorber 43 releases the adsorption of the processing material 41.

Next, the non-inverted conveyance operation will be described with reference to FIGS. 9 to 11. The clockwise rotation of the drive shaft 2 lowers the inner end portions 20b and 21b connected to the first and second rotational arms 20 and 21 so that the first and second horizontal moving members ( When 10) and 11 move inward, the moving teeth 48 and 49 move horizontally in a direction approaching each other. When the drive shaft 2 rotates by a predetermined angle of about 80 degrees, the first and second rotating arms 20 and 21 reach the tipping position shown in FIG. 11, and the movable jig 48 and 49 are approaching. Thus, the processing material 1 is placed on the two moving jig 48, 49 in equal parts. Here, the clockwise rotation of the drive shaft 2 is stopped.

When the fact that the position is reached is detected by a sensor such as a limit switch (not shown), the first adsorber 52 releases the adsorption of the processing material 41, and at the same time, the second adsorption unit 53 is made of the processing material ( 41). Therefore, the workpiece 41 passes from the movable jig 48 to the movable jig 49.

Since the drive shaft 2 reversely rotates from the return position shown in FIG. 11, the first and second rotary arms 20, 21 return to the horizontal position of FIG. Thereby, the processing material 41 stops at the position shown by the 2-dot dotted line in FIG. In this position, the second adsorber 53 releases the adsorption of the processing material 41. This moving distance is the same as the reverse conveyance distance shown in FIGS.

The brakes 14 and 15 operate at the time of non-inverted conveyance. Since this operation is the same, the operation of the brake 14 will be described with reference to FIGS. 12 and 13. When the first rotary arm 20 returns to the horizontal position, as shown in FIG. 12, the contact piece 58 mounted on the movable jig 48 touches the stopper 60 fixed to the support member 59. As shown in FIG. Therefore, a predetermined or more counterclockwise rotational force is applied to the pin 18 so that the pin 18 rotates slightly. Therefore, when the processing material 41 is placed on the movable jig 48, it is kept slightly upward with respect to the horizontal moving line 61. As a result, the tip of the processing material 41 does not protrude to the movable jig 49 at the position to be delivered.

When the first rotational arm 21 rotates to the throwing position shown in FIG. 13, the contact piece 58 contacts the other stopper 62, thereby giving the pin 18 a predetermined or more clockwise rotational force to the pin 18. ) Turn right a bit. Therefore, the tip of the processing material 41 is lowered and placed on the movable jig 49.

According to the present embodiment, since the reverse conveyance and the non-invert conveyance can be switched only by the objects of the reverse jig 37, 38 and the movable jig 48, 49, the switching operation can be simplified. Switching time can be shortened. Moreover, since the rotation angles of the links 25 and 26 and the 1st, 2nd rotation arms 20 and 21 are 90 degrees at maximum, an operation speed can be made quick. In addition, since the operation of the movable part is performed below the guide rail 9, the arm does not touch the arm even if the arm of the take-out device starts before falling out from above the jig, and the conveyance time of the processing material 40 is shortened. You can do it.

In this embodiment, the gears 5, 6, the driven shaft 4, the links 25, 26 correspond to the driving force transmission means of the present invention.

In the present embodiment, the first and second adsorbers may be electromagnets when the processing material 41 is a magnetic material.

As described above, the present invention includes a first rotatably connecting the inner end of the first rotating arm and the inner end of the second rotating arm and movable only the horizontal direction of the first rotating arm and the outer end of the second rotating arm. Two reversing jig, first horizontal moving member and second horizontal moving, which are rotatably supported on the horizontal moving member and the second horizontal moving member, respectively and detachably mounted to the first rotating arm and the second rotating arm, respectively. Each movable jig is provided with two movable jig which are detachably attached to the member, and each jig is equipped with an adsorber for absorbing jig-like workpiece material, and the first rotary arm and the second rotary arm are kept in the horizontal position when not in operation. At the time of operation, the driving force transmission is lowered from the one jig to the dripping position where the processing material is transferred from the other jig to the other jig and returned to the horizontal position again. A means is formed, whereby a reverse jig is used in the case of reverse conveyance, and the other of the first rotary arm and the second rotary arm is rotated downward by 90 degrees and reverse rotated from one reverse jig to the vertical position. The conveying of the processing material to the reversing jig of the reversal is carried out while the working material is reversed by 180 degrees, and in the case of non-inverting conveying, a predetermined smaller than 90 degrees of the first rotating arm and the second rotating arm is used by using the moving jig. Non-inverted conveyance and reverse conveyance are characterized in that the workpiece is moved by turning the workpiece from one movement jig to the other movement jig at an angle and downward rotation and in an approaching position. Can be easily switched by the jig.
