Description

[Detailed Description of the Invention] Industrial field of application The present invention arranges tile bases placed on a conveyor and sequentially conveyed at a predetermined position on the conveyor at regular intervals in the conveyance direction by a constant number. Related to the device.

Problems to be solved by the conventional technology and device In the tile manufacturing process, a plurality of tile bases are formed by a press in a state that they are arranged side by side in the vertical and horizontal directions. When mounting and transporting to the next glazed position, there is a certain amount of space between the tile bases after pressing because of the strength of the press molding die, but glazed with that space as it is. If this is done, a large amount of the sprayed glaze will be wasted without being applied to the tile base material, so it is preferable to arrange the tile base materials by narrowing the intervals before the glaze process.

As an aligning device for this, conventionally, a group of tile bases that move on a pressed alignment conveyor is held in a state in which the front and rear ends are brought into close contact with each other by stopping by abutting against a movable stopper, After that, by driving the movable stopper at a predetermined time interval, the tile bases are sequentially sent to the alignment position with a large interval in the transport direction, and at the same time the leading tile base strikes the fixed stopper provided at the alignment position, The tile base is lifted by a table slightly projecting rearward from the rear end, and at the same time that the subsequent tile base abuts on the rear end surface of the table, the next table protruding the tile base slightly rearward from the rear end. The tile base is lifted from the rear edge of the table by sequentially lifting it up with the subsequent tile base. Is that so as to align in a state in which a slight gap in the same dimensions vacant.

However, such a conventional device is required to convey the tile base material to the front alignment position after the tile base material is blocked from moving by the movable stopper and is continuous in the conveyance direction, and further, when the tile base material is conveyed to this alignment position, Since it was designed to leave a large gap between the tile bases to prevent the subsequent tile bases from riding on the rear end of the table for lifting the tile bases, after temporarily stopping the transfer of the tile bases by the movable stopper, It takes a long time for the last tile base material to be lifted up by the table and the alignment process is completed. Therefore, in recent years when the press cycle has been shortened by the improvement of the press technology, the cycle of the alignment process has been shortened. Could not keep up with the shortening of the press cycle, which was a cause of hindering the improvement of production efficiency.

Means for Solving the Problems As a means for solving the above problems, the present invention is to mount a tile base on a straight running portion of a plurality of thin endless belts in which straight running portions are arranged in parallel at intervals. The conveyor which is designed to be transported by means of a conveyor is provided with a movable stopper that moves between a blocking position where the front end of the tile substrate on the straight running portion abuts and a retracting position that does not interfere with the tile substrate. By a plurality of positions corresponding to each of the group of tile bases that are blocked in transport by the
A plurality of elevating bodies facing the lower surface of each of the tile bases between adjacent straight running portions are provided separately in a plurality of groups that are integrally elevated for each parallel to the transport direction, and the elevating bodies are provided. Are simultaneously raised to project from the upper surface of the straight traveling portion, and are sequentially driven to descend from the front group in the transport direction at arbitrary time intervals so as to be retracted from the upper surface of the straight traveling portion.

The operation and effect of the present invention The present invention having the above-mentioned configuration has a structure in which the press-molded tile bases are moved to the blocking position when they are conveyed on the straight running portion in a group with a large gap in the front-rear direction. By the tile base material in the top row hits and subsequent tile base materials subsequently hit in succession, a group of tile base materials are prevented from being conveyed in a state in which the front and rear ends are in contact with each other, and thereafter, By raising and lowering the elevating bodies all at once and pushing up the lower surface of the corresponding tile bases, all the tile bases are simultaneously lifted from the straight running part of the conveyor, and then the movable stopper moves from the blocking position to the retracted position, The set of elevating bodies lifting the tile base material in the first row descends and retracts below the straight line running portion, so that the tile base material in the first row is placed on the straight line running portion. At the same time, it starts to move forward in the transport direction, and after a short period of time from the start of the descent of the tile base in the first row, the set of lifting bodies that lifts the tile base in the next row that comes in contact with By starting the descent, the tile bases that come into contact with the tile bases are placed on the straight running section and at the same time the tile bases in the first row start moving with a slight gap and a delay. By performing the operations in sequence, a group of tile substrates are transported and aligned in a state where a predetermined narrow interval is provided in the transport direction. It can be arbitrarily adjusted by changing the interval of the descent start time between.

As described above, according to the present invention, once the transfer of the tile bases is stopped, the tile bases are simultaneously lifted up and the tile bases in the first row are sequentially lowered to perform the alignment. Since the process is completed, the time required for the alignment is significantly shortened as compared with the case where the conventional aligning device is used, and it is possible to follow the shortening of the press cycle and improve the production efficiency. There is.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes an alignment for parallelly arranging a plurality of thin endless belts 3, 3 which are paired with each other and which are provided between a driving pulley (not shown) and a driven pulley 2 and are spaced in parallel from each other. In the conveyor, each of the pair of endless belts 3 and 3 is formed with horizontal straight running portions 4 and 4, and the starting end portion of the aligning conveyor 1 is formed into a square shape by a press forming machine (not shown). The carrying-out conveyor 5 for carrying out the tile base material a connected is connected by arranging the end portions of the plurality of linear traveling portions 6 arranged in parallel with the starting end portions of the linear traveling portions 4 of the aligning conveyor 1 respectively.

The movable stopper is movable in the conveying direction of the aligning conveyor 1.
In the state shown in FIG. 4 (a), which corresponds to each tile base a in the rearward direction of the tile base a, the movable stoppers 10 at the blocking position of the group of tile bases abut on the movable stoppers 10 so that the movement is blocked. Elevating bodies 12 facing the lower surface of the tile base a from between the adjacent straight running portions 4 and 4 are arranged at a plurality of positions, and these elevating bodies 12 are arranged in parallel to the conveying direction at right angles. Each one is integrally fixed to an elongated lifter 15 which is fitted in the vertical guide grooves 14, 14 of both support plates 8, 8 across the lower part of the straight traveling part 4, and each lifter Air cylinder connected to both ends of 15
16, the elevating / lowering body 12 passes between the linear traveling portions 4 and 4 and is retracted so as to project below the upper surface of the linear traveling portion 4 and the protruding position where it is projected above the upper surface of the linear traveling portion 4. The lifter 15 is driven up and down with respect to the position.

This embodiment has the above-mentioned structure, and when a group of press-molded tile bases a is transferred from the carry-out conveyor 5 to the aligning conveyor 1 and is carried at intervals x in the carrying direction, as shown in FIG. In addition, the movable stopper 10 is in the blocking position shown by the solid line in the figure, and all the elevating bodies 12 are in the retracted position below the linear traveling unit 4, and the tile base a in the front row contacts the rear surface of the movable stopper 10. As a result, the subsequent transfer of the tile base material a is stopped, and the subsequent tile base materials a are brought into contact with each other one after another, so that the tile base material a slides with the straight line traveling portion 4 as shown in FIG. When the transfer is continued, as shown in FIG. 7B, the air cylinders 16 drive all the lifting bodies 12 to move up and push up the lower surfaces of the tile bases a located above them. Therefore, all tile base a When the movable stopper 10 is driven to rotate in the clockwise direction and is held at the retracted position shown by the chain line in FIG. 7B, the movable stopper 10 is rotated in the clockwise direction. ) And (d), only the elevating bodies 12 that are lifting the tile bases a in the leading row that have been in contact with the movable stopper 10 start to descend, and after these elevating bodies 12 start descending, After a lapse of a very short predetermined time, the elevating body 12 that lifts the tile bases a in the succeeding row, which abuts the tile bases a in the first row, starts to descend, and thereafter, is moved backward in the transport direction at every predetermined time. Lifting body
