Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rotating conveyance device that conveys a molded product formed by a press while rotating it in a horizontal direction.

[Conventional technology]

Conventionally, when molded products formed on a press line are loaded onto a pallet using an automatic loading device, moldings taken out in the final press process are used to stabilize the loading posture, improve the efficiency of the number of sheets accommodated, or improve the efficiency of the post-process. Frequently, items are pivoted horizontally as they are transported to the pick-up point of an automatic loader.

Conventionally, this turning has been performed using a rotating conveyance device, but the conventional rotating conveyance device had the following problems.

[Problem to be solved by the invention]

In conventional swing conveyance equipment, the mounting of the linear guide rail rotates the swing axis by changing the angle.
The fixing means for the linear guide rail does not have high rigidity, and as a result, the guide rail bends during turning, and it is difficult to obtain a smooth turning operation due to photographing.In addition, since the guide rail is fixed at both ends, The structure is complicated because two or more fixing means are required. 'Also, in order to minimize the deflection of the guide rail, the rotation center of the angle conversion is near the center of the guide rail, and as a result, the rotation table when turning to the right and when turning to the left is ±90'' compared to when it is not turning. In addition to this, since the guide rail is straight, the turning operation starts at the same time as the transfer starts and ends at the end point of the transfer, which can easily cause interference with other surrounding equipment at the start and end of the transfer. There were also some glitches.

The present invention has been made in order to improve the above-mentioned problems, and it is an object of the present invention to provide a turning transfer device for press-formed products in which a turning arm is turned by a fixed guide rail having a curve.

[Means and effects for solving the problem] In order to achieve the above object, a carrier provided on a conveyor rail so as to be able to reciprocate, a swing arm supported on the carrier via a pivot shaft, and a rotary arm supported on the carrier through a pivot shaft, a swing mechanism that is fixed along a rail and that provides a swing motion to the swing shaft as the carrier moves, and has an idle rail; and a swing mechanism provided in the swing mechanism;
and a means for selecting the turning direction of the turning axis, so that the turning direction of the molded product can be changed by simply selecting the turning direction using the turning direction selection means of the turning mechanism. The present invention provides a rotating conveyance device.

〔Example〕

An embodiment of the present invention will be described in detail with reference to the drawings.

In the figure, reference numeral 1 denotes the main body of this device, which has a pair of conveyance rails 2 that are parallel to each other along the conveyance direction of the molded product (not shown) taken out in the final process of the press. A carrier 3 is movably mounted on top.

A driving roller 4 and a driven roller 5 are provided on both ends of the conveyance rail 2, and are located between the respective conveyance rails 2, and a portion is fixed to the carrier 3 between these rollers 4.5. An endless belt 6 is wound around the belt.

A drive motor 8 is connected to the drive roller 5 via a reducer 7, and the drive motor 8 causes the belt 6 to
By rotating forward and backward, the carrier 3 is reciprocated along the conveyance rail 21, and a swing arm 25 is provided on the carrier 3, which is turned approximately 90'' to the left or right by a swing mechanism 9. There is.

The turning mechanism 9 has a guide rail 12 installed on the side of the transport rail 2.

As shown in FIG.
It has a shape curved in a gentle curve in the direction of separating from the transport rail 2, and is fixed to a part of the pedestal 1a that supports the transport rail 2. A pair of guide rails 12 are provided on the lower surface of the distal end side of the guide arm 13. A guide roller 14 is adapted to be guided.

The other end of the link 15, one end of which is pivotally supported on the carrier 3 side, is pivotally attached to the other end of the guide arm 13, and the base end of the guide arm 13 is attached to a bell crank 16, which is approximately V-shaped. It is pivoted at one end.

The bent portion of the bell crank 16 is rotatably supported by the carrier 3, and the other end of the bell crank 16 is connected to a right-hand swing lever 18 rotatably supported by a swing shaft 17 via a connecting rod 19. connected.

The pivot shaft 17 is rotatably supported by the carrier 3, and a pair of right pivot levers 18 and a pair of left pivot levers 20 are rotatably supported on the pivot shaft 17, spaced apart in the vertical direction. Additionally, a substantially fan-shaped pivot plate 21 is provided between the pivot levers 18, 20 and is fixed to the pivot shaft 17 and rotates together with the pivot shaft 17.

The rotating plate 21 has a pin hole 21a located at a position that matches the pin holes 18a and 20a provided in the left and right rotating levers 18.20.
, 21b, and a bottle hole 21c is formed at a position that matches the bottle hole 3b of a boss 3a protruding from the carrier 3 between these pin holes 21a and 21b, and a pin hole 21c is formed in each of these pin holes 21a to 21c. By selectively inserting the pin 22, the direction of rotation of the rotation shaft 17 can be selected and fixed.

On the other hand, the left turning lever 20 and a lever 23 provided integrally with the bell crank 16 are connected by a connecting rod 24, and a wipe end portion of a turning arm 25 is fixed to one end of the turning shaft 17. .

The attachment is attached to the rotating arm 25 at the section 25.
A is provided, and these attachments are installed in part 2.
An attachment (not shown) such as a nest for gripping the molded product is detachably attached to the tube 5a.

Next, to explain the operation, first, the turning direction of the turning arm 25 is selected depending on the form of the molded product, etc., but when turning the turning arm 25 to the right, the bottle hole 18a of the right turning lever 18 is selected. The pin 22 is inserted into the pin hole 21a of the rotating plate 21 and set so that they rotate together.

In this state, when the attachment attached to the swing arm 25 holds the molded product and starts conveying it, the swing arm 25 will not turn on the straight portion of the guide rail 12;
When approaching the curved part of the guide rail 12, the bell crank 16 is rotated clockwise in FIG. The lever 18 is also rotated clockwise. Since the right turning lever 18 and the turning plate 21 are connected by a pin 22, the turning arm 25 fixed to the upper end of the turning shaft 17 can be rotated to the right by 90 inches in the direction of arrow A shown in FIG. The molded product held by the attachment is also rotated approximately 90 degrees to the right and transported to the pick-up point of the automatic loading device.

Thereafter, the above operation is repeated, and the molded product taken out from the final process of the press is rotated to the right and transported to the pickup point of the automatic loading device.If the molded product is rotated to the left and transported, use the left rotation lever at the time of setup. 20 and rotating plate 21
Insert the pin 22 between them.

As a result, the clockwise rotation of the bell crank 16 is converted into a left rotation by the lever 23 and the connecting rod 24, and the left rotation lever 2
0 to the left in the direction of arrow B, it becomes possible to turn the molded product to the left, and when transporting the molded product without turning it, the tool 20 is rotated between the bottle hole 21c of the rotating rod 21 and the carrier 3. The rotating plate 21 is fixed to the carrier 3 by inserting the pin 22 into the bottle hole 3b of the boss 3a.

As a result, the left and right turning lever 20 can be moved while the carrier 3 is moving.
．． Since the rotating plate 21 is fixed to the carrier 3 even when the molded product 18 is rotated, the molded product can be transported without rotating.

In the above embodiment, a molded product is transported between the final process of a press line and an automatic loading device, but it goes without saying that the present invention can also be applied to transport of a molded product between presses of a press line.

〔Effect of the invention〕

As described in detail above, this invention allows the rotation direction to be selected by simply replacing the pin provided on the rotation mechanism, making it easy to change the rotation direction and fixing the guide rail of the rotation mechanism instead of the conventional movable type. This eliminates problems such as the guide rail bending or vibrating during turning, making it difficult to turn smoothly.

In addition, by providing a straight section and a curved section on the guide rail, it is possible to prevent interference with other devices at the transport start and end points, and the turning position is different from when turning to the left and right when turning. Problems such as misalignment of ±90° can also be resolved.
