Abstract

PURPOSE:To make the automatic changing of the direction of a tile face by a method wherein the front or back of each tile is judged ahead conveying paths, which are arranged in parallel, so as to change-over the conveying paths for conveying the judged tile on the proper path and the tile is turned over at the terminal of one of the conveying paths. CONSTITUTION:The direction of the face of a tile T on a conveying means 11 is judged with a sensor 41 and the passing of the tile T through the predetermined position is detected with a sensor 42 so as to change the position of a pulley 31 in order to feed the tile T to a lower conveying path 22 when the front of the tile T faces upwards and to feed the tile to an upper conveying path 21 when the back of the tile T faces upwards, The tile T with its front facing upwards is conveyed as it is by the lower conveying path 22 to a conveying means 12. The tile T with its back facing upwards starts to descend by receiving its tip with the receiving member 51 of a tiel turning-over means 50 and, at the same time, turns over by means of its inertia during conveying and falls down at the terminal of the upper conveying path 21. At this time, by controlling the speed of the lower conveying path 22, the fallen tile T is made not to overlap with the tile T conveyed by the lower conveying path 22.

Description

[Detailed description of the invention] [I! (1) Field of Application] The present invention relates to a device for aligning the directions of the surfaces of tiles transported along line I:.

[Prior Art] Tiles are manufactured through various manufacturing processes, or during the manufacturing process of a particular tile, it may be necessary to align the orientation of the tile surfaces.

For example, in the bisque firing process, when firing is performed with the surfaces of the tiles facing each other, the tiles must be aligned so that they are all facing upwards before glazing. Is there a need to let it happen?

For this reason, in the past, tiles that were face down had to be turned face up and arranged by a person.

[Problem to be solved by the invention] As mentioned above, in order to automate the tile manufacturing process, conventionally the tiles that were face down were turned face up by a human hand. There was also a problem that l was also very bad.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a tile surface alignment device that can automatically change the direction of the tile surface.

[Means for Solving the Problems] In order to achieve the above object, the present invention arranges in parallel a transport path for transporting face-up tiles and a transport path for transporting face-down tiles in the middle of a line for transporting tiles. , and sensors for determining whether the tiles are face up or face down are disposed in front of these transfer paths, and sensors are placed in front of these transfer paths to determine whether the tiles are face up or face down, based on the determination result of the sensor means. A switching means is disposed to switch and send the tiles to the respective transfer paths, and a reversing means for reversing the tiles is further disposed at the end of one of the transfer paths.

Preferably, the configuration is such that the time required for tile transfer is the same for the transfer path for transferring face-up tiles and the transfer path for transferring face-down tiles.

[Function] According to the tile surface alignment device having the above-mentioned configuration, a mixture of face-up and face-down tiles that are transported on the same line can be automatically aligned with one side facing either side. It comes.

[Example] Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows an overall side view of an apparatus according to a first embodiment of the present invention.

In the figure, reference numerals 11 and 12 are transfer means, which form a line for transferring the tiles T from a previous process (for example, a firing process) to a next process (for example, a glazing process).

Reference numerals 21 and 22 indicate transfer paths, which are arranged in the vertical direction at an intermediate portion between the transfer means 11 and 12. Of these, the transfer path 21 is located at the top to transfer the tiles T facing the back side, and the transfer path 22 is located at the bottom to transfer the tiles T facing the front side.

In this embodiment, these transfer paths 21 and 22 are formed by pulleys and ropes, and the upper transfer path 21 is formed by pulleys and ropes.
3a, 23b, 23c and ropes 24a, 24b, and the lower transfer path 22 has pulleys 25a, 25b, 25c and rope 26a.

26b are formed respectively. In addition, these transfer paths 2
1.22 is driven by a drive device (not shown), and this drive device is capable of speed adjustment, main adjustment is made by the reduction ratio, and fine adjustment is made by one-frequency control. The moving speeds of 22 can be set to arbitrary speeds.

30 is a switching means which connects the transfer f-stage 11 and the transfer path 21.
It is placed between 22. This 10-stage switching 30 includes a pulley 31 located on the transfer path 21.22 side, and a pulley 31 located on the transfer path 21.
1, and a main pulley 34 with a rope 33 suspended between it and the pulley 31.
It consists of

41, 42, and 43 each have a sensor, and sensor 41
is arranged in front of the transfer path 21, 22, and determines whether the tile transferred on the first transfer stage 11 is facing the front side or the back side. Further, the sensor 42 is a sensor that determines the drive timing of the switching means 30,
When the passage of a tile is detected, the first switching stage 30 is activated after a predetermined time via a timer. This sensor 42 can also be used for sensors 41 and 1. Sensor 43 is switch 10
It detects the accumulation of tiles in the stage 30 and sends a stop signal for the entire line when the accumulation is detected.

Note that an ultrasonic sensor, an optical sensor, or the like may be used as the sensor.

Processing of the signals from each sensor 41, 4, 2, 43, operation of the first switching stage 30, control of the line 41>If or the speed of the transfer path, etc. are performed by a control device which is not shown in detail.

Reference numeral 50 denotes a reversing means, which is disposed near the eave end of the upper transfer path 21 and is constructed as shown in FIGS. 2 to 4. That is, in these drawings, 51 constitutes a reversing means, the receiver is a member, and the pulley 23c is mounted on both sides of the pulley 23c.
It is suspended from the tips of two arms 52 arranged parallel to 3c. The member 51 of this receiver has a hook-shaped side section so that it can securely hold the tile, and is also made of a cushioning material such as rubber or plastic ink to reduce the impact when the tile is received. It is formed by

Further, the receiver is a return member that constitutes the reversing means 50 together with the member 51, that is, the weight s! 53 is attached to the rear end side of each of the two arms 52. The two arms 52 are
Its intermediate portion is swingably supported by a shaft 55 via a bearing member 54. Then, when the tile T is placed on the member 51, the receiver moves down due to the weight of the tile, and when the tile T disappears, it becomes heavy! ! The weight support 53 is designed to allow the member 51 to rise.

As shown in FIG. 4, the arm 52 is slidably inserted into a bearing 54 and fixed at any position by screws 56. Further, the single weight 53 is movably attached to the arm 52 and fixed at an arbitrary position by screws 57.

When the tile transfer speed increases, the inertia also increases accordingly, and the tile tends to jump out further forward at the end of the transfer path 21. Therefore, in such a case, the position of the reversing means is adjusted. That is, the length of the arm 52 extending from the bearing 54 is lengthened, and the bearing is adjusted so that it rubs the member 51 forward, and the single weight 53 is also shifted backward, so that the bearing balances the member 51 and the weight 53. Try to keep it.

Note that the arm 52 has upper and lower limit stoppers 58 and 59.
This prevents the plucking movement beyond a predetermined value.

Reference numeral 61 denotes an air nozzle, which is disposed between two pulleys 23c, and the receiver jets air to the L portion of the tile T that is received by the member 51.

Further, as the return member, it is also possible to use a splinter or the like that can adjust the tension.

The tile surface alignment device having such a configuration operates as follows.

(2) The orientation of the surface of the tile T transferred on the transfer means 11 is determined by the sensor 41.

(2) The sensor 42 detects that the tile T has passed through a predetermined position.

(3) Based on the signals from the sensors 41 and 42, the switching means 30 is switched to be connected to either the upper transfer path 21 or the F section transfer path 22;

In other words, if the tile T is facing up, the lower transfer path 21
The driving means 32 is operated to move the pulley 31 so that the tile T is sent to the upper transfer path 22 when the tile T is facing down.
change the position of

(4) The face-up tile T is transferred by the lower transfer path 22 and sent to the transfer means 12 as it is. Note that the lower transfer path 22, which has a somewhat longer transfer distance, is connected to the rope 26a.
, 26b are made somewhat faster so that the time required to transfer the tiles in the upper transfer path is equal to the time required to transfer the tiles in the lower transfer path.

(5) The face-down tile T is transported by the 1] section transport path 21. Then, at the end of the eaves of the transfer path 21, the tile T is received by the member 51 at the tip of the holder of the tile inversion r-stage 50 and begins to descend, and is reversed by inertia during transfer and falls.

At this time, if the speed of the lower transfer path 22 is adjusted as described above, the tile T that has been turned over and fallen,
There is no separation from the tile T that has been transferred through the F section transfer path 22.

As a result, the face-down tiles T are turned face-up, and all of the tiles T to be transferred to the next stage are turned face-up yffl.

Note that when the tile in the first inversion r stage 50 is removed, the weight 23 quickly returns to the state Fff in which the receiving member 51 can stop the first tile T.

1. Normally, the receiver can reverse the tile only by lowering the member 51 and the inertia trusted by the tile, or if the tile transfer speed is to be increased or the tile is to be more reliably reversed, air is supplied from the air nozzle 61. It is preferable to make it squirt.

In this way, when the receiver uses the reversing means having the member 51, the member 51 partially receives the tile, reducing the inertia acting on the tile, and mitigating the impact when the tile is reversed and dropped. . At the same time, by preventing the tip of the tile from moving and applying inertia only to the top, the tile T can be reliably reversed with a small rotation locus.

FIG. 5 shows an overall side view of an apparatus according to a second embodiment of the present invention.

This embodiment differs from the first embodiment in that only the nozzle 61 is used as the reversing means. in this case,
The reversal of the tile T is performed by inertia during transportation and the urging force of air jetted toward the top of the tile T from the nozzle 61. Therefore, it is preferable to use it for aligning the surfaces of tiles that are less likely to be damaged, since the impact when the tile T is reversed and falls is relatively large.

The present invention is not limited to the above embodiments, but includes various modifications within the scope of the gist.

For example, it can also be applied when all tiles are turned face down, in which case the face up tiles are sent to the upper transport path,
Send face down tiles to the lower transport path. Further, the balance between the speeds of the upper transfer path 21 and the lower transfer path 22 may be achieved by adjusting the speeds of only the upper transfer path 21 or the speeds of the upper transfer path 21 and the lower transfer path 22.

[Effects of the Invention] As described above, according to the tile surface alignment device of the present invention, it is possible to automatically align and align the tile surfaces.
