Abstract

PURPOSE:To make a sheet work possible to be turned over as far as 180 degrees as synchronized with a press, by coupling a lever to be rocked by a cam and a turn arm together so as to cause the turn arm to be rotated as far as 180 deg. by rotation of a camshaft, in case of a press line. CONSTITUTION:A turn arm 3 provided with a jaw is installed in a pair of bodies 1 adjacent to a press free of rotation as far as 180 deg., while a lever 39 to be rocked by a cam and the turn arm 3 are coumpled together by rotation of a cam shaft as far as 180 deg. via a segment gear 10 being fitted in a spline shaft 8, an intermediate gear 11 and a gear being tightly attached to a turning shaft 13. Thus, the sheet work formed with a double-action press is turned over as far as 180 deg. by a turnover device, and it is conveyable as synchronized with the press to the next transfer press.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a turnover device for reversing a sheet material formed by, for example, a double-acting press and transporting it to the next transfer press.

Jaws that operate by clamping and unclamping with conventional technology cylinders,
A turnover device is known in which a carrier is rotatably rotated 180 degrees by a motor, and the jaws take out a sheet material formed by a double-acting press, turn it around 12, and convey it to the next transfer press.

Problems to be Solved by the Invention With such a device, it is difficult to synchronize the 180-degree rotation of the jaw with the double-action press, and the sheet material cannot be smoothly reversed. have

A pair of bodies 1 are provided facing each other, each body 1 is provided with a turn arm rotatable through 180 degrees, and the press is adjacent to the press. A cam is provided on a camshaft that is connected to the power takeoff shaft of The turn arm can be rotated 180 degrees using the rotation of the shaft.

Embodiment A turnover C sheet material take-out mechanism and a sheet material conveyance mechanism E are disposed between a double acting press A and a transfer press B which are spaced apart in the left-right direction.

The turnover C includes a pair of front and rear main bodies 1°I,
This main body 1 has a turn arm 3 with jaws 2 at 18
A pair of front and rear jaws 2 are mounted so that they can rotate freely by 0 degrees.
are facing each other and gripping both the front and rear edges of the sheet material F and rotating the turn arm 3 by 180 degrees to rotate the sheet material F by 180 degrees.
It is designed to be able to be reversed.

The pair of front and rear main bodies 1 are movable in the front and rear directions along a pair of left and right guide rails 5 disposed at the front and rear of the base 40, and are rotated by a pair of front and rear feed motors 6, 6. are respectively screwed together with the feed screw rod 7,
When the feed screw rod 7 is rotated forward and backward by the feed motor 6, the main body 1 is moved in the front and back direction so that the distance between the pair of jaws 2 can be adjusted, and a spline shaft 8 is fitted to each main body 1. Each spline shaft 8 is connected by a shaft 9, and segment gears 10 are spline-fitted to each other, and each segment gear 10 is connected to an intermediate gear 11. The gear 12 is valved and connected to a rotating shaft 13, and the turn arm 3 is fixed to this rotating shaft 13, and a reaction cylinder 14 is pivotally connected between this rotating shaft 13 and the main body I, so that the turn The arm 3 is held in a horizontal position facing the double acting press A.

The sheet material take-out mechanism includes a pair of front and rear sheet material supports 20.degree. 20 disposed between a pair of jaws 2.2, and a first carrier 22 that can move left and right along a guide rail 21. The carrier 22 has a pair of subcarriers 23
is provided with a cylinder 24 so as to be movable in the left-right direction, and a jaw 25 is mounted on each sub-carrier 23 diagonally upward toward the double-acting brace A.

The kite rail 21 is movable up and down by a vertical rod 27 and a guide 28, and is held in a lowered position by a lift cylinder 29 to rotate a segment gear 31 meshed with rack teeth 30 of the vertical rod 27. It is supposed to rise.

In FIG. 5, 32 is a camshaft, which is disposed vertically between the double-acting press A and the transfer press B, and is connected to the power take-off shaft 34 of the double-acting press A via a gear group 33.
A turning cam 35, a lifting cam 36, and an unloading cam 37 are fixed to this cam shaft 32, and a first lever 38, which is swung by the turning cam 35, is pivoted to the shaft 9 via a first link 39. connected,
Second lever 4 swung by lifting cam 36
0 is connected to each of the segment gears 31 via the 20th bolt 4I and the 30th bolt 42, and the unloading cam 3
A third lever 43 pivoted at 7 is connected to the first carrier 22 at a 40th lever 44.

The sheet material conveyance mechanism E includes the pair of guide rails 21.
The second carrier 50 is provided with a second carrier 50 that can freely travel along the
The carrier 50 is connected to the first carrier 22 by a shaft 51, and the second carrier 50 is provided with first and second sheet material receiving portions 52 and 53, which move the sheet material F from the reversing position I to the intermediate position. It is designed so that it can be transported from one location to another. In other words, the first and second sheet material receivers are
A sheet support material 54 is arranged adjacent to the seed support material 54, and as the second carrier 50 descends together with the first carrier 22, the sheet material is supported on the seed support material 54.

The unloading position is the clamping position of the pair of transfer bars 60, 60 of the transfer press B, and is set so that the sheet material F can be clamped by the pair of transfer bars 60, 60. A material lifter 61 is provided, and as shown in FIG. 6, this sheet material lifter 61 makes a lifting table 62 vertically movable by means of a rack rod 63 and a pinion 64, and connects the pinion 64 to a motor 65. The table 62 is held in a lowered position by a cylinder 67, and by rotating a motor 65, the elevating table 62 can be raised.The elevating table 62 is also provided with a support plate 66.

Then, the sheet material F formed by the double-acting press A is taken out onto the sheet material support 20 in synchronization with the double-acting press A by the sheet material take-out mechanism, and then both ends of the sheet material F are taken out by the jaws 2 of the turnover C. Grasp the edge and turn arm 3
By rotating the press 180 degrees, the sheet material F can be reversed 180 degrees vertically in synchronization with the double-acting press A and placed in the reverse position I.
Thereafter, by moving the second carrier 50 vertically and horizontally in rectangular motion in synchronization with the double-acting press A, the sheet material F can be conveyed to the discharge position (2).

Then, at the unloading position (3), the support plate 66 is moved up and down by the elevating table 62 to move the sheet material F to the tran 27 and the arbor 6.
It can be positioned at a flang height position of 0, clamped by the transformer 7 aber 60, and transported by the transfer press BtlC.

Further, since the cam shaft 32 is provided vertically and each cam is mounted horizontally, it is necessary to arrange the cam shaft 32 and each cam on the floor and form a bit on the floor.

Further, the jaw 25 for taking out the sheet material is provided on a subcarrier 2 movably provided on the first carrier 22 with a cylinder 24.
3, sheet materials of different widths can be taken out without changing the two strokes of the first carrier 22.

Further, the first carrier 22 and the first carrier 50 are connected, and the first carrier 22 and the turnover C
Since the turn arm 3 is rotated vertically and horizontally by 180 degrees by a cam provided on the same cam shaft 32, the sheet material take-out, sheet material reversal, and sheet material conveyance are performed synchronously.

Effects of the Invention Since the turn arm 3 can be rotated 180 degrees by the camshaft 320 rotated by the power output shaft 34 of the press, the sheet material can be reversed 180 degrees in synchronization with the press.
