The unfinished tiles A are sent off by this send-off conveyor 4 to the next process, which assures good efficiency in the after-treatment work of the unfinished tiles A.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tile base post-processing conveyance device for conveying a tile base formed by a press to a post-processing process.

In general, in a press that performs dry molding of tile bases, the press operation is stopped every time the number of times the tile base is molded reaches a certain value because the raw material powder adheres to the mold surface when compression molding the powder raw materials. In recent years, the molding speed of tile substrates has increased in this type of press, and the molded tile substrates can be fed out one after another at short intervals. On the other hand, in the conventional tie A/substrate post-processing conveyance device,
Since the conveyor device for post-processing is directly connected to the press, in order to send the tile substrate that is delivered at short intervals during press operation to the post-processing process, it is necessary to use a conveyor system that is as short as or even shorter than that of the press. It is necessary to feed at time intervals, so the conveyor speed of the conveyor device must be high, and the tie IV substrate may be caught or damaged by the guide on the conveyor or each post-processing device in the conveyor device. There was a problem that caused trouble.

Therefore, the present invention aims to solve the above problems.
Even when the tile base is formed in a press at high speed and the tile base is fed one after another at high speed from the press,
By allowing for the downtime of the press, those tile substrates can be transported at a relatively low speed for the post-processing process, which can reduce troubles when transporting tile substrates due to higher press speeds. It is an object of the present invention to provide a post-processing and conveying device for tile substrates.

In this height detection device 4, the optical axis line is the table 21.
The piston loft 17a of the cylinder 17 is lowered to a height where the optical axis is no longer blocked by the upper tie 1L/rope A. The column is a transfer device that transfers the tile substrate A on the round belt 8.8 received by the stopper 9 onto the tape IL/21.

The column is an elevating cylinder fixed to the transfer body 6, and a suction cup 9 capable of suctioning the upper surface of the tile base is fixed to the lower end of the piston loft 2Ba. This suction cup 9 is connected to a suction device (not shown) via an electromagnetic valve (not shown), and the suction action starts when it is moved above the round belt 8.8.
) When the table 21 is moved upward, the suction action is stopped. The cycle time of the operation of the transfer device is set to 2.5 seconds so that the tile substrates conveyed on the round belt 8.8 can be transferred one after another. Next, (I) is a supply section that is capable of delivering the tile substrate A received in the storage section 4 to the delivery conveyor system @4 at a speed that is one step slower than the receiving speed in the storage section (2). The conveyor side part is configured as follows. The configuration of this supply section is as follows:

The height detection device 1t22B for each supply unit is positioned so that its optical axis crosses a position slightly lower than the top surface of the table 21B at the highest position (an amount smaller than the thickness of the tile base). . This height detecting device 22B detects the piston loft of the cylinder 17B up to the height at which the optical axis is no longer blocked by (8) when the tile base A on the table 21B is taken out. Also, the horizontal cylinder 27B has a suction cup 29.

The round bell at 4) 11 can be moved to a position above 11. When the suction cup 29B is moved above the table 21B, the suction action is started, and when it is moved above the round bell 21B, the suction action is stopped.

In the case of the above structure, when this is operated, the tie/L/base material A are formed one after another in a cycle time of 2.5 seconds by the press L, and the round belt 8.8 is rotated 20 times by the supply conveyor device. sent upwards. The tile base material A fed onto the round belt 8.8 is placed on the round belt 8.8 at predetermined intervals and conveyed sequentially, and then transferred to the top 8.8 of the round belt 8.8. Near the end of the section, it is temporarily stopped by a stopper 9, whereby the first tie A' blanks conveyed by the nine belts 8.8 in 98 rows are aligned in a straight line. Next, in the storage section of the delivery device 5, when the tile body A is received by the stopper 9 and aligned as described above, a detection device (not shown) detects this, and the detection signal causes the tile to be transferred.

is lowered, and the suction cup 4 is brought into contact with the tile substrate A which is received by the stopper 9. The suction action is started before the suction cup is brought into contact with the tile base A as described above, for example, when the transfer f/F-6 is moved above the stopper 9. Therefore, when the suction cup is brought into contact with the tile base A, this ygo attracts the tile base A. Next, the piston rod 28& of the elevating cylinder row rises, and the suction cup 9 moves the tile base material to the round belt 8.

is moved slightly above the table 21, after which the suction action of the suction cup 4 is stopped and the tile base layer falls onto the tape A/2]. In this case, the suction action of the suction cup may be stopped while the tie/I/base material A is placed on the table 4 without being dropped. Next, the piston rod 23a of the lifting cylinder rises to raise the suction cup 4 to its original height, and then the piston rod 27& of the lateral movement cylinder d retracts and retreats the suction cup 4 to its original position above the stopper 9. move it. Then, when the next second tile maker is received by the stopper 9 and aligned at h,
The transfer device repeats the above series of operations again, places this second tile substrate A on the first tile substrate A on the table 21, and thereafter repeats the above operations at a cycle time of 2.5 seconds. Repeat. Further, when the tile base board is placed on the table 4 as described above, this tile base board blocks the optical axis of the height detector ρ, and the signal from the height detector ρ causes the piston rod of the cylinder 17 to 17 &
is lowered. The lowering of the piston rod 17 & is stopped when the tile base A on the table 21 no longer blocks the optical axis, so that the upper surface of the tile base A is approximately the same as the upper surface of the original table 2 (11). located at a height. In this way, the tape/L'21 is lowered by approximately the thickness of the tile base A each time a tile base A is placed on it, so that the top surface of the tile base A stacked on the table 2 is on the palm of the hand. is maintained at approximately the same height. When, for example, 100 tile base layers are press-molded as described above, the press 1 is pressed for a predetermined period of time, e.g.
The operation is stopped for 0 seconds, and the mold is cleaned during this stoppage.

After 50 seconds have elapsed, the tile bases A are again formed one after another with a cycle time of 2.5 seconds. Next, the above table 2
When 100 tile substrates A are placed on the table 1, at the latest by this point, the lower surface of the tile substrate layer on the table η is V bell due to the lowering of the table 21 due to the above-mentioned loading)
This V-belt 14 , 14 is received by 14 , 14 .
The piston rod 1 of the cylinder 17

When the piston rod 178B of cylinder B is moved to the rising end, the piston rod 178B of this cylinder 17B (
12) is lowered to lower the table 21B so that its upper surface is lower than the upper surface of the upper transition portion of the V-belts 14, 14. After that, when the descending end of the piston rod 17aB of the cylinder 17B and the descending end of the piston rod 17& of the cylinder 17 are confirmed, the V belt 14
, 14 are rotated by a predetermined amount in the direction of the arrow, whereby the tile base layer transferred onto the V bell (14) and 14 in the storage section (14) is moved from the receiving position (a) to the storage position (b). In addition, the tile base layer located at the storage position in (c) is moved to the take-out position in (c). after that,
The horizontal movement cylinder 27B of the transfer device M'23B operates to move the suction cup 29B above the tile base layer at the removal position (c), and then the elevating cylinder 28B operates to move the suction cup 29B
B is lowered, and thereby the suction cup 29B comes into contact with the tile base material A at the top of the tile base layer and suctions this tile base member. After that, the lifting cylinder 28B returns and lifts the tile base, and then the horizontal movement cylinder 27B
is operated to return and moves the tile base to the top of the round bells (11, 11) of the delivery conveyor device 4. Thereafter, the lifting cylinder 28B operates again to lower the tile base A, and then the suction action of the suction cup 2 [1B is stopped and the tile base A falls onto the round pe V) 11,11. This round bell) 11.

The tile base material A dropped onto ll is then conveyed to the next process by the rotation of the bell) 11°11. As mentioned above, when the tie/L' substrate A on the table 21B is taken out by the transfer device [23B, the optical axis of the height detection device 22B is no longer blocked, so the piston rod 17aB of the cylinder 17B is be raised. The upward movement of the piston rod 178B is stopped when the optical axis is again interrupted by the uppermost tile accumulator, so that the upper surface of the tile base layer on the table 21B is always at approximately the same height. be done. A series of operations of the transfer device 23B are repeated in sequence to transfer the tile bases on the table 21B onto the round bells 11, 11 one after another.

The cycle time of this post-loading M23B can be set to a relatively long time that takes into account the downtime for cleaning the mold of the press 1. For example, the downtime of the press 1 is 60.
Transfer and load [D
The cycle time of B can be 8.0 seconds. Therefore, the conveyance speed of the delivery conveyor device 4 can be made much lower than the conveyance speed of the supply conveyor device 2, and the tile substrate A can be conveyed to the post-processing step without undue stress. By repeating the operations described above, even while the feeding of the tile base A from the press 1 is interrupted for cleaning the mold, the tie A'
The base material A can be continuously supplied.

When the tile base material on l is moved to just below the suction cup 29Be of the transfer device 23Be waiting above the take-out position, the rotation is stopped, and the suction cup 29Be moves the tile l on the take-out position.
v When the substrate A is attracted and lifted, it is rotated again in the direction of the arrow. In addition, the stroke of the horizontal movement cylinder 27e of the transfer device 23a is configured to be large, so that the piston rod 27ae moves to the forward end (15). Move the terminal end upwards. Since the cycle time of this transfer device row e is shorter than the cycle time of the other transfer device 23Be, the suction cup 29el of the transfer device 23e

Therefore, the release position of the tile base moves to the right every cycle of operation of the transfer device 23e, resulting in
The number of tile blanks on 4a increases, and the release position is finally moved to near the top of the starting end of the upper transition section of round bell) 14e. At this point, the press operation is stopped and the round belt 1 is
4 The capacity of tile substrate A on a is set. Therefore, during the mold cleaning time, the supply of the tile base material A onto the round bell (14B) is stopped, but the transfer of the tile base material A onto the delivery conveyor device 4e continues without interruption at a low speed. The tile base material A on 14B gradually decreases, and returns to the initial state shown in FIG. 5 by the time the mold cleaning is completed and the molding of the tile base A is started again (16).

It should be noted that parts that are considered to have the same or equivalent structure as those in the previous figure in terms of function are given the same reference numerals as in the previous figure with the letter e, and redundant explanations are omitted.

As described above, the present invention includes a supply conveyor device 2 which receives the tile base material A formed by the press 1 and conveys it to the next stage, and a supply conveyor device 2 which is designed to receive the tile base material A formed by the press 1 and convey it to the next stage, and a supply conveyor device 2 which is designed to receive the tile base material A formed by the press 1 and convey it to the next stage. A delivery conveyor device 4 for delivery

The tile blank that has been molded and transported by the supply conveyor device @2 can be sent to the next process by the delivery conveyor device 4, and thereby J) IL/S1
The tile blanks formed by this can be sent to the post-processing process one after another, and the post-processing work of the tile blank A can be carried out smoothly.

Further, even though the press 1 is configured to stop operating for a predetermined period of time every partial cycle of tile base molding, the delivery device 5 is conveyed to the side of the supply conveyor device 2 by the supply conveyor device 2. The storage section ■, which can receive the tile substrates A one after another, is connected to the delivery conveyor device f.
A large supply section (toward) is provided on the side part, which is capable of sending out the tile wood blocks received in the storage section (2) toward the delivery conveyor device 4 at a speed slower than the receiving speed at the storage section (2). When transporting the tile base material A from the press 1 to the post-processing process using the h, the tile base materials delivered one after another from the press 1 at short time intervals are stored in the storage section. and the storage section 15 [

This stored tile material is supplied to the delivery conveyor device 4 at a time interval that is slower than the time interval during the storage, and the tile material A is delivered to the delivery conveyor device 4 even while the press 1 is out of operation. Therefore, the conveyance speed of the delivery conveyor device 4 can be made lower than the conveyance speed of the supply conveyor device 2, so that even if the conveyance speed of the supply conveyor device 2 is considerably high, the delivery speed of the delivery conveyor device 4 can be made lower than that of the supply conveyor device 2. This has the effect of not only increasing the operational stability of No. 4 but also significantly reducing the chance of the tile substrate getting caught or damaged in the post-processing process.
