Description

[Detailed description of the invention]

1 Industrial Field of Application 1 The present invention is a sagger filling device used when packing a plurality of tile substrates (some of which have previously hidden glaze on the surface of the substrate) in parallel into a sagger for tile firing. Regarding the improvement of

[Prior art l] Traditionally, as a sagger-packed gi device, patent application No. 51-1107
There is one related to No. 66 (Japanese Unexamined Patent Publication No. 51-124669@). That is, as shown in FIG. 6, this sagger filling position is located between the [phase] of the tile base filling position on both sides of the circulating passage △ formed in the vertical plane and the inverted position O at the top of this passage A. A plurality of sets of tile substrate parallel holding mechanisms 1 are provided which circulate between the passage A and the sagger filling position Q at the bottom. Each tile substrate parallel holding mechanism 1 has a clamping tool 3 which is in a sideways state toward the outer periphery side toward the circulation path at the tile substrate loading position ■■, and has a tile substrate insertion gap 2 between them.
A plurality of the holding tools 3, 3, . . . are released in parallel at the sagger filling position @G. Each tile substrate parallel holding mechanism 1 is connected to an endlessly stretched chain 4, and is connected to an FIA between adjacent tile substrates inserted.
It is intermittently transferred in the direction of the outline arrow B by the chain 4 at a feed pitch P corresponding to an interval of 2.2. Each tile substrate parallel holding machine H41 performs the following operations during the intermittent transfer. At the above-mentioned tile substrate filling position, the tile substrate facing upward is inserted into each tile substrate insertion gap 2 formed between the clamping tools 3 and 3 which are in the non-holding state.
are sequentially inserted by the tile insertion mechanism 5 in the state shown in the upper left corner of the figure. Next, in the process from the position @ where the tile base [ has been inserted ] to the upper reversal position ■, the clamping tools 3, 3, etc. are operated and the tile base [, [
...Hold it so that it does not tilt. Continuing on, in the process from the reversal position O to the position ■ before the insertion of the next tile substrate starts, the clamping tools 3.3... are released to the non-holding state and the state shown in the upper right of the figure shall be. Further, it moves to the tile base inserting position [phase] in the non-holding state. At this tile substrate filling position (■), one tile substrate [face-up] is placed on top of the tile substrate [that has already been inserted into each tile substrate insertion gap 2] by the tile insertion mechanism 6, as shown in the lower right corner of the figure. They are inserted one after another so that the state is the same. Next, move from the position where the tile base material t has been inserted at the tile base material filling position ■ to the sagger filling position Q.
In the process of reaching the sagger filling position 0, the clamping tools 3, 3... are operated again to hold the tile base (...) to prevent it from falling off. , 3... are suddenly changed to the non-holding state, and the lower part of the group of parallel tiles consisting of the tiles arranged in parallel in the raised sagger 7 is dropped.
The intermittent drive of the chain 4 is stopped until the sagger 7 is lowered after the parallel tile group T is dropped into the sagger 1. Finally, when the tile group T has been discharged, it is transferred from the sagger filling position G to the original tile base filling position. [Problems to be Solved by the Invention 1] However, the conventional sagger filling device has the following problems. (al) Each tile substrate parallel holding mechanism 1 is connected to a chain 4 stretched in an endless manner and transported intermittently. However, the chain 4 stretched under a constant tension tends to stretch after long-term use. Therefore, each tile substrate parallel holding mechanism 1 cannot stop at the predetermined tile insertion position, which is the tile substrate filling position I), and the tile substrates to be inserted into the tile substrate insertion gap 2 are [W7J may hit the clamping tool 3 and be damaged.For this reason, in the conventional device, it was necessary to frequently perform maintenance and inspection of the chain 4, and the operating efficiency was extremely low. (b) Sagger It is necessary to stop the intermittent drive of the endless chain 4 while the sagger 7 is being lowered after dropping the j tile group T lined up in the tile base 7. However, all tile substrate parallel holding mechanisms 1, 1... is a set of endless chains 4
Therefore, while the chain 4 is stopped, the tile substrate parallel holding machine M%1 at the tile substrate packing position ■■ also stops. As a result, the tile base material cannot be inserted, resulting in wasted time for the tile base parallel holding mechanism 1 located at the tile base filling position [■■. In order to solve the above-mentioned problems, the present invention is capable of stopping the tile substrate parallel holding mechanism at a predetermined intermittent stop position at the tile substrate filling position, and eliminates the above-mentioned wasted time. (Means for Solving the Problems) The gist of the sagger filling device according to the present invention (hereinafter referred to as ``the present invention device J'') is to provide a sagger filling device formed in a vertical plane. A plurality of tile base parallel holding mechanisms are provided that circulate between the tile base filling position on both sides of the passage, the inversion position at the top of this passage, and the sagger filling position at the bottom of this passage, and each tile base is held in parallel. The mechanism includes a plurality of clamping tools that are arranged side by side at the tile base stuffing position so as to fall sideways toward the outer periphery of the circulating passage and forming a tile base insertion gap between them, and at the sagger base stuffing position. This releases the holding operation of the clamping tool, and outside of the tile base filling position on both sides of the circulation path, there are tile bases to be inserted into the tile base insertion gap of tile base parallel holding R#4. In the sagger filling device provided with an insertion mechanism, the tile substrate parallel holding mechanism includes a rack provided along the direction in which the clamping tools are arranged side by side, and a pinion in the center that engages with the rack at the tile loading position. and an upper pinion that engages with the rack at the inverted position, and a lower pinion that engages with the rack at the sagger filling position, and the center pinion and the upper and lower pinions have respective distances between their axes. ('J), an intermittent driving means for intermittently driving a central pinion at a feed angle corresponding to the interval between adjacent tile substrate insertion gaps of the tile substrate parallel holding mechanism; The feeding drive means for driving the upper and lower pinions is provided by ¥Q4). [Function] The action of the device of the present invention will be explained based on the embodiment shown in the drawings. The left and right tile bases are held in parallel at the tile base filling position ■■ on both the left and right sides of aisle A @@11.
0 are engaged, and the tile substrates are intermittently transferred at a feeding pitch P corresponding to the interval between the tile substrate insertion gaps 12, 12. While this intermittent transfer is stopped, each tile substrate parallel holding mechanism 11 inserts the tile substrate t into the tile substrate insertion gap 12 formed between the clamping tools 13 and 13 which are in the non-holding state. It is inserted at step 15 (or 16). Tile substrate parallel holding fil located at the tile substrate packing position on the left

Continuing, when the sagger 7 descends, the tile substrate parallel holding mechanism 11 is driven again by the lower pinion 19 to a position where it abuts the tile substrate parallel holding mechanism 11 on the left (FIG.
(see B)). [Embodiments] The present device will be described below based on embodiments, not shown in the drawings.

The device of the present invention eliminates the collision between the tile base and the clamping tool that occurs in conventional devices, and improves the yield in the tile manufacturing process. ■ With conventional VT@, the chain stretches, so maintenance and inspection of the chain must be performed frequently. On the other hand, since the device of the present invention uses a rack and pinion instead of a chain, there is almost no need for maintenance and inspection, and the operating efficiency can be improved. ■ With conventional equipment, when the tile base parallel holding mechanism is stopped at the sagger filling position, the tile base parallel holding mechanism located at the tile base filling position cannot be intermittently fed. There was wasted time. However, with the device of the present invention, even if the tile base parallel holding mechanism is stopped at the sagger filling position, tile bases can be inserted by intermittently feeding the tile base parallel holding R mechanism located at the tile base filling position. This eliminates wasted time. As a result, the device according to the present invention can improve processing capacity by about 20% compared to conventional devices.
