Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying member changing device for a conveying device used in a press machine.

Conventional conveyance devices for press machines have a conveyor member such as a vacuum cup or jaw attached to a feed bar that moves in two or three dimensions using bolts or a clamp mechanism, and when replacing the conveyor member, the bolt or clamp mechanism must be used. Workers directly operate and replace the parts manually.

For this reason, there is a problem that replacing the conveying member is extremely troublesome.

The present invention has been made in view of the above circumstances, and its purpose is to provide a conveyance member exchange device for a conveyance device for a press machine, which allows the conveyance member to be automatically exchanged.

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

FIG. 1 is a perspective view, and the press body 1 has an approximately C-shape including an upper body 2, an intermediate body 3, and a lower body 4, and the upper body 2 has a slide 5.
is vertically movable, and the lower body 4 is provided with a bed 6.

A rail 8 is provided on both side surfaces 2a, 2a of the upper body 2 via a pair of brackets 7, 7 and extends outward from both side surfaces 2a, 2a at a position above and in front of the press body 1. The main body 9 is provided so as to be slidable in the longitudinal direction (arrow X ₁ ).

A vertical hole 10 is bored in the main body 9, and this vertical hole 1
A rod 11 is fitted into the inside of the rod 11 and is moved vertically (in the direction of arrow Z) by a cylinder 12, and the rod 11 is provided with an elevating body 13.

A horizontal hole 14 is bored in the elevating body 13, and a rod 15 is fitted into the horizontal hole 14 so as to be slidable in the front-rear direction (arrow Y direction).
A piston rod 16a is connected to the piston rod 16a.

A holder 17 is fixed to the rod 15, a hole 18 in the longitudinal direction is bored in the holder 17, and a movable rod 19 is inserted in the hole 18 in the longitudinal direction (arrow X ₂
The movable rod 19 is provided with a first conveying member ₂₀₁ such as a vacuum cup, and is slid in the longitudinal direction by a cylinder (not shown). The arm 21 provided in the
₂ , 20 ₃ , and 20 ₄ are fixedly installed.

In FIG. 2, a is a pallet on which blanks b are placed, which is conveyed to a side position of the press body 1 by a cylinder c etc. in the direction of the arrow, and d
is the molded product delivery conveyor, and the molded product pallet e
The molded products are conveyed to , and the molded product pallet e is moved in the direction of the arrow.

Further, D is a storage shelf provided on the side of the press main body 1, and a plurality of shelves are formed at intervals vertically.
Conveying members of different shapes are stored in D ₁ , D ₂ . . . .

The second to fourth conveying members 20 ₂ to 20 ₄ are the third conveying members 20 2 to 20 4 .
As shown in the figure, they are each attached to a three-pronged arm member 22, and a mounting rod 23 is integrally formed on the arm member 22, and is detachably fitted and attached to the arm 21 as shown in FIG. be.

In other words, the arm 21 has a cylinder tube 24.
is bolted, and a large diameter hole 25 is bored in its inner peripheral wall 24a, and a cylinder 26 is fitted into this large diameter hole 25. Mounting hole 27 facing the front and back direction,
28 is drilled through the cylinder tube 24 so that the mounting rod 23 is fitted therein, and a piston 29 is fitted into the cylinder tube 24 so as to _be slidable in the longitudinal direction. The piston ₂₉ is provided with a retaining piece 31 that fits and locks into the notch recess 30 that serves as the locking portion of the mounting rod 23, and the piston 29 is pulled out by a spring 32. When the stopper piece 31 is urged to slide in a direction to come out of the notch recess 30 and pressure oil is supplied to the first chamber ₂₄₁ , the stopper piece 31 is slid in a direction to fit into the notch recess 30.

By moving _the main body ₉ to the left in the direction of arrow By moving the main body ₉ upward and to the _right in the direction _{of arrow} The molded products are adsorbed and transported to the molded product delivery conveyor d.

The holder 17 may be moved forward and backward in the Y direction.

In addition, when replacing the second to fourth conveying members ₂₀₂ to ₂₀₄ , the main body 9 is moved to the side of the press main body 1, and the holder 17 is moved to face the storage shelf D as shown in FIG. , move the holder 17 rearward to the second
~ The fourth conveying member 20 ₂ ~ 20 ₄ is entered into the predetermined shelf D ₁ and the elevating body 13 is lowered to remove the shelf.
Place and store on _D1 . At this time, the protrusion 22a of the arm member 22 is positioned so as not to contact the shelf _D1 and move in the front-back direction.

Then, when the pressure oil in the first chamber ₂₄₁ is discharged and the piston 29 is slid by the spring 32, the retaining piece 31 is released from the notch recess 30, and the retainer 17 is moved forward, the cylinder is moved from the mounting rod 23. The tube 24 comes out and the conveying members 20 ₂ to 20 are removed from the arm 21.
₄ are separated.

After that, the elevating body 13 is moved up and down to position it facing the shelf D ₂ where the predetermined transport members 20 ₂ to 20 ₄ are stored, and when the holder 17 is moved backward, the mounting rod 23 is inserted into the holes 27 and 28. When the piston 29 is slid by supplying pressure oil to the first chamber 24 ₁ , the retaining piece 31 is fitted and locked in the notch recess 30 , and the new conveying member 20 is attached to the arm 21 . ₂ to 20
Install ₄ .

Then, the elevating body 13 is raised and the holder 17 is moved forward to create a new conveying member 20 ₂
~20 ₄ is taken out from shelf D ₂ and the next conveyance operation is performed.

In this way, the transport member 20 can be automatically replaced using the operation of the transport device itself.

Incidentally, the elevating body 13 and the holder 17 may be moved up and down and back and forth using a rack and pinion. Further, a DC servo motor may be used as the drive source.

The present invention is as described above, in which the main body 9 is moved in the left-right direction along the rail 8, the elevating body 13 is moved in the vertical direction with respect to the main body 9, and the rod 1
5 in the front-rear direction with respect to the elevating body 13, the conveying member can be moved in the left-right, up-down, and front-back directions, so that the molded product can be conveyed by the conveying member.

Further, the arm member 23 is fitted into the mounting hole 28 of the arm 21 provided in the holder 17 facing in the front-rear direction, and the retaining piece 31 is moved by fluid pressure to fit into the notch recess 30 of the arm member 23. By doing so, the conveying member is transferred to the rod 15 via the arm 21 and the holder 17.
Since it can be firmly attached to the mold, the molded product can be transported reliably using the transport member.

Further, by releasing the fluid pressure and moving the retaining piece 31 in the opposite direction to that described above using the spring force, the arm member 23 can be pulled out from the hole 28 by detaching from the notch recess 30, and the conveying member 23 can be pulled out from the hole 28 in the same manner as described above. The arm member 22 is placed on the shelf D ₁ by moving in the left-right, up-down, and front-back directions, and
When the rod ₁₅ is moved backward and the arm 21 is moved backward again, the mounting rod 23 comes out of the hole 28 and the conveyance member is stored in the storage shelf D together with the arm member 23. In this state, by performing the opposite operation to that described above, the conveying member stored in the storage shelf D can be attached to the arm 21 together with the arm member 23.

Therefore, the conveying member can be automatically replaced by utilizing the movement of the conveying member.
