Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lateral moving inter-mold conveying device that transports products by moving laterally between the dies of a press using multiple dies.

Conventionally, presses used a method of rectangular movement using an air-driven transfer hand for conveyance between winter molds, but the time taken to move back and forth toward the mold was large and the movement itself was slow, so it was difficult to save time. Therefore, this back-and-forth movement can be eliminated and lateral movement parallel to the mold and lift-down movement can be performed, reducing setup time and making it possible to adjust the height of the feed line, resulting in a highly stable lateral movement type inter-mold transfer. The aim is to provide the equipment.

To explain the drawing of one embodiment of the present invention, 7 is a carrier body for transporting products of this device, one side is guided by a guide bar 3 installed on the conveyor frame 1, and the other side is installed on the conveyor frame 1. A separate lateral movement drive device (for example, a conventional drive device such as a crank mechanism or a cylinder device) (not shown) is used to hold the guide plate 4 between the followers 5 and 6 attached to the top and bottom of the carrier body 7 at two locations on the left and right sides. 3) so that it can be moved laterally parallel to the mold 36.

A lifting cylinder 8 is attached to the carrier body 7, and a rack 12 fixed to the tip of a rod 9 of the lifting cylinder 8, a pinion shaft 13 that meshes with the rack, and a lever 14 fixed to the pinion shaft 13 are built-in. When the cylinder 8 is actuated, the pinion shaft 13 is rotated by the rack 12, and the lever 14 fixed to the pinion shaft 13 is turned around the pinion shaft 13 by a maximum of 180 degrees.

A link 15 is pivotally connected to the lever 14 via a pin 2, and a clevis 1 is attached to the other end of the link 15 via a pin 16.
An adjustment screw 18 is loosely attached to the clevis 17, and an arm 20 is fixed to a nut 19 that is engaged with the adjustment screw 18.

Therefore, the lever 14 is centered around the pinion shaft 13, and the pin 2
, if the arm 20 is rotated by 180 degrees to the bottom dead center, the arm 20 will move up and down by the amplitude of the single string motion of the pin 2.

A nut 38 is fixed to the carrier body 7 at a position facing the lifting cylinder 8, and the nut 38 has an adjustment screw 22 with a shock absorber 23 fixed to the right end thereof.
is screwed on and is prevented from rotating by a lock nut 21. When the lock nut 21 is loosened and the adjustment screw 22 is turned clockwise, the shock absorber 23 advances to the right and regulates the end position of the rack 12.
By shortening the stroke length of the lever 14, the turning angle of the lever 14 is reduced, and the length of the vertical movement of the arm 20, that is, the lift stroke can be adjusted.

Since the cylinder 8 and the retreating end pin 2 are always at the top dead center,
Strictly speaking, regulating the end position of the rack will regulate the lower limit of the arm.

A lock nut 24 is screwed into the adjustment screw 18 to prevent the adjustment screw 18 from rotating relative to the nut 19, and a handle 25 is attached to the upper end of the adjustment screw 18. The engagement position between the adjusting screw 18 and the nut 19 is adjusted, and the absolute height position of the arm 20 is changed, that is, the height of the feed line can be adjusted.

The left end of the arm 20 is connected to a clevis portion 29a at the right rear end of the distal arm 29 by a pin 30, and the head is pivotally attached to both sides of the rear end of the clevis portion 29a by pins 28. The bolt 27 is engaged with a notch 33a of a stop plate 33 fixed to the upper surface of the arm 20, and the nut 2
6, the tip arm 29 is fixed to the arm 20.

Conversely, when the nut 26 is loosened and the bolt 27 is tilted circumferentially outward using the pin 28 as a fulcrum, the tip arm 29 is moved to the pin 3.
0 as a fulcrum and can be lifted upward by approximately 100 degrees, and the entire apparatus can be moved laterally with respect to the press without the tip arm 29 interfering with the column 37 of the press.

A joint 39 is fixed to the tip of the tip arm 29, and a hole 3 passing through a boss portion 39a of the joint 39
9b is curved so as to be perfectly aligned with the hole 29b provided at the tip of the tip arm 29 so that an insertion portion 31b protruding from the center of the clamper portion 31 to which an ori, vacuum cup, etc. is attached can be inserted.

The upper half of the boss portion 39a is separated from the joint 39, and the upper central portion 39c is slotted, and a bolt 40 screwed in perpendicularly to the slotted portion can be tightened by the lever 32. This allows the hole 39b to be reduced and the insertion portion 31b of the clamper to be fixed.

Therefore, the cleanser 31 can be easily attached to and detached from the joint 39 and the tip arm 29 by one-touch operation of the lever 32.

Further, arms 29c extend from the left and right sides of the tip arm 29, and a U-shaped groove 29d is provided at the tip of the arm 29c, which supports the clamper portion 31 by sandwiching it therebetween so as to balance the weight of the clamper portion 31 from side to side.

Guide bars 34 and 35 are fixed to the arm 20 at two locations, and the guide bars 34 and 35 are guided by the carrier body 7 via linear motion bearings and pivotally connect the tip arm 29 and the arm 20. pin 30
In the center of is a block 1 attached to the tip of the rod 11a.
A balance cylinder 11 is configured to push up a pin 30 fitted with a pin 30, thereby relieving a large moment caused by the clamper portion 31, the tip arm 29, and the conveyed product, thereby allowing smooth vertical movement.
is attached to.

According to the present invention, the transfer hand for multi-space transportation has the following features and effects, and can reduce the transportation setup time.

(1) The clamper part is lever 32 and joint 3
By the action of 9, it can be attached and detached with one touch.

(2) By making the clamper mounting part foldable, it is possible to move the main body laterally without interfering with the press column.

(3) The large moment of the cantilever clamper is alleviated by the balance cylinder.

(4) The operation of the lifting cylinder is converted from rack and pinion motion to crank motion to form a sine curve and eliminate shock.

(5) The height of the feed line can be adjusted using the upper handle.
