[0002]

2. Description of the Related Art In general, a tile is formed by pressing a soil kneaded by a soil kneading machine with a press device, and the tile is placed on a drying pallet, dried and fired. Conventionally, a tile press conveyor, a repeater having a tile alignment function, and a suction-type transfer device are provided between a press device and a drying pallet, and a tile press formed by the press device is used for the tile press conveyor. The transfer device picks up multiple tiles in the unloading area of the conveyor with a transfer device and temporarily transfers them to the repeater, and then sucks the tiles in the repeater with the transfer device and transfers them to the drying pallet. Like that.

[0003] Tiles are deformed during the drying process.
A plurality of tiles are placed on one drying pallet, and the tiles located near the blower and the tiles located far away have different drying methods even on the same drying pallet. Since the difference in drying is directly linked to the difference in deformation, the supporting position of the tile on the drying pallet is determined in detail for each tile in consideration of the difference in the manner of deformation associated with such drying. For this reason, conventionally, a repeater with a tile alignment function was installed between the tile press conveyor and the drying pallet, and the tile base was temporarily transferred from the tile press conveyor to the repeater, where it was aligned with the supporting position of the drying pallet. The arrangement of the tiles was adjusted.

[0004]

Five tiles K in the unloading area 2s are to be lifted by a suction-type transfer device (not shown).

Thus, the tile press conveyor 2 of the present invention
Has a roof tile aligning device 200 integrated in a portion of the conveyor frame 2a corresponding to the lower surface of the unloading area 2s. As shown in FIG. 3, the roof alignment device 200 includes a lifting cylinder 20 on a conveyor frame 2a.
1 and a vertically movable frame 202 of a rigid structure, which is attached to the vertical frame 202, a sliding frame 204 of the same rigid structure installed on the vertically movable frame 202 via a sliding guide member 203, and a sliding frame 204 of the same. It is roughly composed of five positioning plates 205 erected on the upper surface.

As described above, the elevating frame 202 and the sliding frame 204 are connected via the sliding guide member 203. When the elevating frame 202 is moved up and down by the elevating cylinder 201, the elevating frame 202 slides on the elevating frame 202. The frame 204 moves up and down together. In addition, lifting frame 2
02 and the sliding frame 204 are connected via a sliding cylinder 206, and the sliding frame 204 reciprocates linearly on the lifting frame 202 by moving the rod of the sliding cylinder 206 forward and backward. Sliding frame 204
Plate-shaped stoppers 207 are vertically provided at both ends of
The movement range of the sliding frame 204 is regulated by contacting the stoppers 207 with regulating members 208 provided at both ends of the lifting frame 202.

The restricting member 208 of this embodiment includes a nut 208a fixed to the lifting frame 202 and a bolt 208b.
Through which the bolt 208b is tightened to change the amount of protrusion from the nut 208a. When the regulating member 208 has such an adjustable structure, the moving range of the sliding frame 204 can be freely adjusted to some extent. The regulating member 20

The distance between the five positioning plates 205 erected on the upper surface of the sliding frame 204 is set in accordance with the support position of the drying pallet 4. Each positioning plate 205 is fixed to the sliding frame 204 with a bolt 209 as shown in FIG. 3, but a bolt hole (not shown) of the positioning plate 205 is formed in a long hole shape. The position of the positioning plate 205 can be finely adjusted individually within the range of the length. The positioning plate 205 has such a condition that the upper edge does not interfere with the bottom of the tile receiver 2d when the sliding frame 204 is at the lowered position (hereinafter referred to as an inactive position), that is, the condition that the transport of the tile substrate K is not hindered. When the sliding frame 204 is at the raised position (hereinafter referred to as the "operating position"), the height of the sliding frame 204 satisfies both the conditions that the upper edge enters the gap between the tile substrates K lined up on the tile receiver 2d.

As shown in FIGS. 2 and 5, a fixed auxiliary stand 8 is provided on the side surface of the conveyor frame 2a of the tile press conveyor 2 at a position side by side with the unloading area 2s. The auxiliary base 8 is provided with a tile K in the unloading area 2s.
Is used for temporary storage. As shown in FIG. 5, the pallet area 3 has a space in which three drying pallets 4 are arranged in a row,
(Not shown) for traversing the sheet is provided. An empty drying pallet 4 is placed on the conveyor in the pallet area 3 at the end near the tile conveyer 2 and at the center.

Next, the operation of the tile press conveyor 2 of the present invention will be described with reference to the tile production line shown in FIG. The soil J kneaded by the soil kneading machine and cut into a predetermined shape as described above is supplied to the press device 1 to form the tile body K. Then, the tile substrate K is transported in a state of being lined up on the tile receiver 2d of the tile press conveyor 2, and five tile substrates K are arranged in the unloading area 2s. The unloading area 2
Until the tiles K are completely lined up in s, the elevating frame 202 and the sliding frame 204 of the tile alignment device 200 are in the state shown in FIG.
And the positioning plate 205 is in the inoperative position.

Since the tile press conveyor 2 is operated intermittently in synchronization with the press device 1, there is a timing at which the tile base K is temporarily stopped. In accordance with the stop timing, the tile arrangement device 200 operates as shown in FIGS. That is, first, as shown in FIG. 4B, the elevating cylinder 201 is operated to raise the elevating frame 202 and the sliding frame 204 integrally, and the positioning plate 205 is raised to the operating position. Next, as shown in FIG. 4C, the rod of the sliding cylinder 206 is pulled in to slide the sliding frame 204 in the direction of arrow y. Then, sliding frame 2
The positioning plate 205 moves in parallel with the transport direction of the tile K together with 04, and pushes back the tip of the tile K. By this operation, the tile base K shifts on the upper surface of the tile receiver 2d. The positioning plate 205 is connected to the stopper 20 of the sliding frame 204.
7 stops when it hits the regulating member 208 of the elevating frame 202. The stop position is set so that the arrangement of the tiles K in the unloading area 2s exactly matches the support position of the drying pallet 4. Therefore, positioning plate 2
The tile substrate K stopped by being pressed by the pallet 05
It is arranged to exactly fit the bearing position. In addition,
If the tiles K aligned during use are misaligned, the tightening of the bolts 208b of the regulating member 208 and the position of the positioning plate 205 are changed and adjusted appropriately.

Next, the tiles K in the unloading area 2s are lifted by the suction type transfer device, and if the auxiliary table 8 is empty, the tiles K are placed thereon. On the other hand, the tile alignment device 200
Lowers the elevating frame 202 and the sliding frame 204 to return the positioning plate 205 to the inoperative position.
Extend the rod 06 and return to the initial position.

Next, when five subsequent tiles K are arranged in the empty unloading area 2s, the tile arrangement device 200 is operated in the above-described manner to adjust the position of the tile K. Then, the transfer device is operated again, and the tile K in the unloading area 2s is moved.
And two rows of tiles K on the auxiliary table 8 are lifted together and transferred to an empty drying pallet 4 at the end of the pallet area 3.

It is also possible to directly transfer the tiles K in the unloading area 2s to the drying pallet 4 one row at a time without using the auxiliary table 8, but this would increase the moving amount of the transfer device, As a result, there is a possibility that the processing speed decreases and the running cost of the transfer device increases. In other words, the auxiliary bases 8 are juxtaposed beside the unloading area 2s, the tiles K that have been aligned by the tile alignment device 200 are temporarily transferred to the auxiliary base 8, and then the tiles K that have been aligned in the unloading areas 2s. Pallet 4 for drying by combining
, The burden on the transfer device is reduced,
Benefits such as an improvement in processing speed and a reduction in running cost of the transfer device can be obtained.

Next, as shown in FIG. 6 (a), the drying pallet 4 on which the tile K is placed is placed on a fork 5 of a pallet transfer machine 5.
A and lifts the pallet truck 6A for loading as shown in FIG. 6 (b). A pallet truck 6B on which the dried tile K is placed is arranged beside the pallet truck 6A, and is dried from the pallet truck 6B by the other fork 5B of the pallet transfer machine 5 as shown in FIG. Lift the pallet 4 for use. Then, as shown in FIG. 6C, the drying pallet 4 is taken out from the pallet truck 6B, and the pallet transfer machine 5 returns to the initial position. Next, as shown in FIG. 5, the dried tile K from the drying pallet 4 that has just been lowered is transported by another transfer device (not shown), placed on the transfer conveyor 7 and the auxiliary table 9, and placed on the transfer conveyor 7. After the tiles K are transported, the tiles K placed on the auxiliary stand 9 are transferred to the transfer conveyor 7.

Next, the empty drying pallet 4 in the center of the pallet area 3 is moved sideways as shown by the dashed line in FIG. 6 (c) to the edge, and the dried tile K is lowered. The emptying drying pallet 4 is fed sideways to the center to prepare for the next operation.

By repeating the above operation, the pallet truck 6A can be fully loaded with the drying pallets 4, and at the same time, all the drying pallets 4 can be dropped from the adjacent pallet truck 6B. Then, the pallet truck 6A moves to a drying step (not shown), the empty pallet truck 6B moves to the place of the pallet truck 6A, and another pallet truck (not shown) full of dried tiles is formed. Pallet truck 6
It moves to the place of B and returns to the state of FIG.

As apparent from the above description, FIG.
The method of loading and unloading the drying pallets shown in (a) to (c) uses a space having a size in which at least two (preferably three) drying pallets 4 are arranged in a row in the pallet area 3 and a drying space. A pallet truck 6A for loading and a pallet truck 6B for unloading are arranged side by side outside the pallet region 3 so that the pallet region 3 is sandwiched. The pallet transfer machine 5 is installed at a position facing the pallet trucks 6A and 6B, and the drying pallet 4 in the pallet area 3 is loaded on the pallet truck 6A by the forward movement of the pallet transfer machine 5, and the pallet transfer machine is moved. By returning to step 5, the drying pallet 4 on the pallet truck 6B is lowered to the pallet area 3, and the dried tile K on the drying pallet 4 is lowered. At the same time, the pallet transfer machine 5 can be used efficiently by taking the means of traversing the empty drying pallet 4 by the traversing means and moving it to the position where the tile K before drying is placed. In addition, the present invention is designed to exhibit excellent effects in improving the processing speed and reducing the running cost.

Although the embodiment of the tile press conveyor 2 of the present invention has been described above, the present invention is not limited to the above embodiment. For example, the tile alignment device 200
Although the embodiment incorporated in the conveyor frame 2a has been illustrated, other than that, the positioning plate 205 (or a component corresponding to the positioning plate 205) may be exposed from above the tile substrate K, provided outside the conveyor frame 2a. . Of course, in such a case, measures are taken to make the tile alignment device 200 movable so as not to hinder the transfer device. In addition, the positioning plate 205 pushes the tip of the tile substrate K to shift the tile substrate K in a direction opposite to the transport direction, but pushes the rear end of the tile substrate K to push the tile substrate K in the same direction as the transport direction. It may be shifted.

[0027]

According to the tile press conveyor of the present invention, since the tile aligning device is installed corresponding to the unloading area, the work of adjusting the arrangement of the tile base to the supporting position of the drying pallet can be performed in the unloading area. it can. Therefore, the tiled substrate can be directly transferred from the tile press conveyor to the drying pallet, so that the conventional repeater becomes unnecessary, and as a result, firstly, the apparatus becomes compact and can be installed in a narrow space. Second, there is no need to provide a repeater, which makes it possible to reduce costs. Third, there is no need to go through a repeater, so that the overall processing capacity is improved accordingly. The effect is that the movement is simplified and the burden can be reduced. In addition, if the tile alignment device is configured as in claim 2, it can be implemented with a simple structure at low cost.
