Abstract

PURPOSE:To safely reverse an article by uniting together two pairs of L-shaped devices in such a manner as to freely slide on each other, which are installed in a rotating member to clamp the article from the upper and lower sides. CONSTITUTION:L-shaped devices L1, L2 disposed in a ring supported by rollers comprise members 14, 12, 21 having rollers 14, 16, 24. The device L1 comprises members 11, 12, and the device L2 comprises members 21, 22. The device L2 is moved up and down by an actuator 3 to clamp a work W between the members 11, 21 to be reversed. Thus, the work can be carried in and out easily and reliably, and the operation can be acomplished in a stable state.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an up-down reversing device, and although not particularly limited thereto, it relates to an apparatus which is effective when used to up-down revert a casting core wooden form or the like.

2. Description of the Related Art In recent years, various devices have been proposed for turning a work upside down while the work is being transferred by a conveyor or the like. However, for example, when the outer dimensions of a wooden form with a core for casting are varied, and the outer shape is irregular, it is necessary to turn it upside down and transfer it onto the next conveyor. No such device could be found, and the emergence of such an up-and-down inverting device was desired.

Therefore, in this invention, two sets of shapes each consisting of a horizontal member and a vertical member are combined with the horizontal members (-) facing each other, and the vertical members are slidable with respect to each other. A two-way transfer device is installed, and a fluid actuator that expands and contracts in the direction of the vertical members is interposed between the two sets of L-shapes, and the combined two sets of L-shapes are moved around the axis in the direction perpendicular to these members. By making it rotatable, the above-mentioned demand can be met.

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

Reference numeral 11 indicates a first horizontal member, and reference numeral 12 indicates a first vertical member. Both members 11 and 12 are integrated into an L-shape to constitute a first L-shaped tool.

A reinforcing member 13 is fixed to the member 12 opposite to the member 11. Thus members 11 and 12
An integral first L-shaped tool is constructed.

14 is a two-way transfer device installed inside the member 11. The device 14 may be of a known construction, such as Trapolol (trade name), which can be moved in two mutually orthogonal directions.

The L-shape may incorporate reinforcements at its open (right-hand side in FIG. 1) ends.

21 is a second horizontal member, 22 is a second vertical member, and both members 21. ! = 22 is integrated into an L-shape to form a second wedge.

24 is a two-way transfer device installed inside the member 21, similar to the one described above.

With the members 11 and 21 facing each other as shown, the members 12 and 22 are assembled so as to be slidable in that direction. In this embodiment, rollers 25 and 25 supported by the member 22 are fitted in a guide 15 provided inside the member 12, and the outside of the member 22 is in contact with a number of rows 216 arranged in a row on the member 12. ,
The means for said sliding is constructed.

Reference numeral 3 denotes a fluid actuator which is mounted between two sets of L-shaped tools L1 and between the members 11.21 in this embodiment, in the direction of the members 21.22.

□ 4 is a high pressure air source such as an air compressor. A valve 5 is connected between the air source 4 and the actuator 3 as shown in the figure. Connect the pressure reducing valve 6 and the switching valve 7. Note that hydraulic pressure may be used as the working fluid, and in that case, a high-pressure hydraulic power source is used instead of the high-pressure air source.

8 is a pair of rings, which include the aforementioned shape Ll and Ll,
The four corners of the ring 8 are assembled inside the ring 8. And these rings 8 are set separately.

It is rotatably supported on a roller 8b which is rotatably supported on a hollow shaft 8a. 8C is ring 8
For example, a Cheno sprocket installed on the outer periphery of the
The chino is wound between it and a small diameter chino sprocket that is rotated by power (not shown), and the rotation angle of the ring 8 is forced. Also, instead of the Cheno sprocket, a spur gear may be used and meshed with the 1st pinion. Furthermore, in the upright position shown in Figure 1 of the ring 8 and the inverted position rotated by 180 degrees, the upper surfaces of the supports 14 and 24 are at the same level, and the front and rear of these structures (left and right in Figure 2) are as follows: It is assumed that longitudinal transfer conveyors C01 and CO (details not shown) are installed at the same level as the devices 14 and 24.

However, the upper surfaces of the devices 14 and 24 are not necessarily at the same level, and the levels of the conveyors CO and CO1 may also be stepped.

Next, the operation of the above-mentioned structure will be described.

On the conveyor CO1, there is a wooden formwork W filled with sand.
is loaded and transferred from left to right in FIG. 2, and rides on the device 14 (FIG. 1).

Next, switch the switching valve 7 to the left in the figure. Then, the actuator 3 will contract and the frame W will move between members 11 and 21.
(Fig. 3(a)).

Then, due to the operation of a power (not shown), the ring 8 rotates, that is, rotates counterclockwise in FIG. 1, and tilts with the member 22 facing downward.

Accordingly, the frame W slides toward the member 22 due to the rolling of the devices 14 and 24, and comes into contact with the member 22 (FIG. 3(b)).

When the workpiece W is further rotated by 90 degrees from the beginning, the workpiece W is stably placed on the member 22, and depending on the shape of the workpiece W, it assumes an inclined posture (FIG. 3 (Q)).

When it is rotated further and rotated 180 degrees from the beginning, the top and bottom are reversed, the frame W rides on the member 12, and due to gravity, it extends against the operating pressure of the actuator 3, and the member 12 hits the member 13. The noses that touch each other.

In this state, the top surface of the device 24 is at the same level as the conveyor CO, and the frame W is turned upside down and the conveyor CO! It is then transferred to the next work process, where the mold is removed and the core mold is taken out.

In addition to the above-mentioned embodiments, the present invention can also be applied to, for example, an actuator 3.
In short, each method within the scope of the technical idea of this invention, such as making it a single-acting type, or making the device capable of rotating the two sets of L shapes with a configuration other than a combination of a ring and a roller, etc. Replacement with structural equivalents is also within the technical scope of this invention.

As described above, this invention has a simple structure, and even irregularly shaped transfer workpieces, such as wooden molds for core removal of castings, can be reliably turned upside down and transferred to the subsequent conveyor. , which has a unique and remarkable effect.
