Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an upright tile conveyor, and more particularly, to an upright tile conveyor configured so that tiles that are sent in a horizontal state can be conveyed in an upright position.

In the process of manufacturing roof tiles, it becomes necessary to transport the roof tiles, which are transported in a horizontal state, in an upright position.

The present invention has been made in response to the above-mentioned needs, and it is an object of the present invention to provide an upright tile conveyor capable of displacing horizontal tiles to a vertical position and then transporting the tiles while maintaining the vertical position. .

Hereinafter, the present invention will be described in detail together with embodiments shown in the drawings.

FIG. 1 and the following illustrate one embodiment of the present invention, in which a tile upright conveyor, designated as a whole by reference numeral 1, includes a slat conveyor 2 formed with no ends, and a side of the slat conveyor 2 also formed with no ends. A chain conveyor 3 located on the side, and an upright mechanism section 4 that displaces the tiles from a horizontal state to a vertical state.
It consists of.

As is clear from FIG. 2, the slat conveyor 2 is made up of a large number of rectangular slats 5 connected together so as to be flexible, and includes a drive roller 7 and a guide roller that are supported on a device frame 6. 8 and is suspended endlessly.

On the other hand, the chain conveyor 3 is stretched endlessly between a drive roller 9 attached coaxially with the drive roller 7 and a guide roller 10, and the operating surface of the chain conveyor 3 is placed on the side of the slat conveyor 2. are arranged perpendicular to the operating plane of the slat conveyor 2.

A large number of guide rollers 11 are attached to the chain conveyor 3 at regular intervals.

As is clear from FIGS. 1 and 2, the operating plane of these guide rods 11 is in a plane that includes the entire chain conveyor 3, that is, is vertical, until it reaches the upper guide roller 10. Once it passes the guide roller 10, it gradually falls down toward the slat conveyor 2, and eventually becomes horizontal and continues to run at the same speed as the slat conveyor 2, and as it approaches the drive roller 9, it becomes vertical again. It is configured.

Although such movement of the guide rod 11 is not shown, it may be performed by a cam or the like disposed on the side surface of the chain conveyor 3, and the means for doing so may be freely selected.

By the way, the structure of the upright mechanism section 4 is as follows.

That is, a hydraulic cylinder 12 is fixed below the device frame 6, and the lower end of a swing lever 14 is rotatably supported at the tip of a sliding rod 13 by a pin 15.

As is clear from FIG. 2, the swinging levers 14 are arranged symmetrically on the left and right sides, and are rotatably supported on the device frame 6 via a rotating shaft 16, with the lower end being supported by a connecting rod 17. connected.

Further, the upper end of the swing lever 14 has on its inner side a clamping plate 19 which is moved toward or away from each other by a small hydraulic cylinder 1B attached to the outer surface of the swinging lever 14.

Further, below the swing lever 14, a cam plate 21 rotatably supported by a pin 20 is attached to the device frame 6, and this cam plate 21 is rotated around the pin 20 by a coil spring 22 as shown in FIG. It is given the habit of turning in a clockwise direction.

The lower end of the stopper 23 is in contact with the cam plate 21, and the cam plate 21 is formed into a substantially T-shape when viewed from the direction in which the tiles 26 travel.

The horizontal portion 23a at the upper end of this stopper 23 is in the same plane as the clamping plate 19 when the swing lever 14 is at its clockwise rotation limit in FIG.

Further, the horizontal portion 23a at the upper end of the stopper 23 is formed in a direction perpendicular to the plane of FIG.
The tile 26 is positioned so that it can be easily held, and detection means is provided for activating the upright mechanism section 4.

On the other hand, on the side of the portion of the swing lever 14 corresponding to the rotation shaft 16, there is an arc-shaped cam surface 21a at the tip of the cam plate 21.
A guide roller 25 is provided in a protruding manner, and the guide roller 25 constantly presses the cam plate 21 in the counterclockwise direction.

Next, the operation of the present invention configured as above will be explained.

First, as shown in FIG. 1, the tile indicated by the reference numeral 26 is kept in a horizontal state by a roller conveyor 27 or the like and is transported to a position where it hits the horizontal portion 23a of the stopper 23.

At this time, the clamping plate 19 at the upper end of the swinging lever 14 is in a position in front of the stopper 23, as shown by the solid line in FIG. is open.

At this time, the guide roller 25 protruding from the side of the swing lever 14 presses the cam plate 21 downward, so that the horizontal part 23a of the stopper 23 and the clamping plate 19 are located in the same plane. ing.

When the tile 26 comes into contact with the stopper 23, the tile 26 is stopped at a predetermined position, and at the same time, a detection means such as a limit switch (not shown) detects this and operates the cylinder 12 of the upright mechanism section 4. A signal is sent, the cylinder 12 is activated, the tip of its sliding rod 13 protrudes, and at the same time the cylinder 18 is activated, the clamping plates 19 clamp the tile 26 from both sides, and the swinging lever 14 rotates around the rotating shaft 16. The tile 26 is rotated about 90 times at an angle as shown by the arrow in FIG. 1, and the tile 26 is moved from the horizontal state to the vertical state on the slat conveyor 2.

Through this operation, the roof tile 26, which was in a horizontal state, becomes vertical, and is positioned between the guide rods 11 of the chain conveyor 3, which is running at a constant speed in synchronization with the slat conveyor 2.

On the other hand, when the tile 26 is transferred from the roller conveyor 27 to the slat conveyor 2 by the upright mechanism section 4, the swing lever 14
A guide roller 25 protruding from the cam surface 21a moves the first
It rolls as shown by the chain line arrow in the figure.

At the same time, the cam plate 21 is rotated clockwise about the pin 20 by the coil spring 22 against the pressing force of the guide roller 25, and the tile 26 is transferred.

During this time, the stopper 23 is positioned as shown in FIG. 1 and stops the next tile 26 to be transferred so as not to be erroneously fed.

Then, when it is confirmed that the tile 26 has been transferred to the slat conveyor 2 direction, the cylinder 18 returns to its original state and releases the tile 26.

The roof tile 26 has its lower end in contact with the top of the slat conveyor 2,
The guide rod 11 holds the upper part of the paper and transports it while maintaining the vertical state.

During this time, the swing lever 14 immediately returns to its original state due to the operation of the cylinder 12 and stands by in preparation for the next operation.

After that, when tiles 26 are transferred again, the same operation as described above is repeated, and the tiles 26 are sequentially kept in a vertical state and transferred to the next process.

As is clear from the above description, according to the present invention, the roof tiles that are sent one after another in a horizontal state are held by a swinging lever equipped with a holding plate, and are displaced to a vertical state, and the tiles are moved by a guide rod of a chain conveyor. This makes it possible to transport the tiles on a slat conveyor while maintaining a vertical state, greatly contributing to the automation of the tile manufacturing process, and exhibiting excellent effects such as not causing any damage to the tiles.

Also, since the stopper has a horizontal part, the roof tiles transferred by the roller conveyor are slightly oriented and held.

Even in a state where it is difficult to do so, it is possible to reliably position the device at the correct position on the horizontal portion.
