Background
Conventionally, roller kilns have been used as production firing equipment for, for example, positive electrode materials of lithium ion batteries. Among such roller kilns, roller kilns are known in which the magazines containing the objects to be fired such as the positive electrode materials are conveyed in a plurality of rows in the furnace width direction, but in recent years, in order to increase the throughput, the number of conveying rows is increased and the furnace length is increased.

Fig. 1 shows an example in which the objects to be fired are arranged in 6 rows. In the drawings, the frame of the roller kiln 1 and the like is shown by a single-dot chain line.
As shown in fig. 3B and the like, the roller kiln 1 includes: a first roller conveyor 2 that conveys a plurality of saggers 10 in a state of being arranged in a plurality of rows; a second roller conveyor 3 provided on the exit side of the roller kiln 1 and capable of switching between a low-speed state in which the conveying speed is the same as or slower than that of the first roller conveyor 2 and a high-speed state in which the conveying speed is faster than that of the first roller conveyor 2; and a stopper 4 provided on the downstream side of the second roller conveyor 3 for restricting conveyance and stopping of the sagger 10.
The roller kiln 1 is provided with a third roller conveyor 9 which is provided between the first roller conveyor 2 and the second roller conveyor 3 and can be switched between a low-speed state in which the conveying speed is the same as that of the first roller conveyor 2 or the conveying speed is slower than that of the first roller conveyor 2 and a high-speed state in which the conveying speed is faster than that of the first roller conveyor 2. The low-speed state of the second roller conveyor 3 and the third roller conveyor 9 includes: the second roller conveyor 3 and the third roller conveyor 9 are not driven, and the rollers of the roller conveyors 3 and 9 are stopped, or the roller conveyors are not driven, but the sagger on the roller conveyors 3 and 9 is pressed by the sagger conveyed subsequently, and the rollers are rotated. The third roller conveyor 9 is preferably a stacked roller conveyor. The transport speed in the low-speed state may be, for example, 20 to 60mm/min, which is the same as the transport speed of the first roller conveyor, and 1000 to 1500mm/min, which is the transport speed in the high-speed state.
As shown in fig. 3B, an atmosphere replacement chamber 8 is provided on the exit side of the roller kiln 1, and the second roller conveyor 3 and the stopper 4 are disposed in a region 12 on the entrance side of the atmosphere replacement chamber 8. The first roller conveyor 2 is disposed in a region 11 on the upstream side of the second roller conveyor 3. In the atmosphere replacement chamber 8, the baffle 80 divides the chamber into a plurality of chambers 81 and 82, and for example, an atmosphere gas such as nitrogen is introduced into the chambers 81 and 82 to prevent oxidation of the material to be fired and cool the material to be fired. The cooled object to be treated is conveyed to a recovery device, not shown, by a roller conveyor 20.
The stopper 4 is provided on the downstream side of the second roller conveyor 3, and can be switched between a stopped state in which the conveyance of the sagger 10 is stopped by being disposed in front of the conveyance direction X of the sagger 10 and in contact with the sagger 10, and a conveyance state in which the conveyance of the sagger 10 is permitted by being retracted from the front of the conveyance direction of the sagger 10.
As shown in fig. 2 and the like, the roller kiln 1 includes: an elevator 5 that separates the plurality of saggers 10 stopped by the stopper 4 upward from the second roller conveyor 3; a widthwise movement supporting member 6 for supporting the sagger 10 separated upward by the lifter 5 so as to be movable in the widthwise direction Y of the roller kiln 1; and a widthwise position adjustment member 7 that sandwiches the sagger 10 from both outer sides in the widthwise direction Y in a state where the sagger 10 is separated from the second roller conveyor 3, and adjusts the position of the sagger 10 in the widthwise direction Y to a predetermined position. As shown in fig. 2, the widthwise movable support member 6 includes a plurality of rollers 61.
The roller kiln 1 further includes: first detection means 91a, 91b, 92a, 92b for detecting that the sagger 10 reaches the third roller conveyor 9; and second detection means 93a, 93b for detecting that the sagger 10 reaches the stopper 4. In the present embodiment, a description will be given below of an example in which a photoelectric sensor including light emitting portions 91a, 92a, 93a, 94a and light receiving portions 91b, 92b, 93b, 94b is used as a detection device including a first detection device and a second detection device, but the detection device is not limited to a photoelectric sensor, and a known detection device can be used.
The stopper 4 includes: an abutting portion 41 abutting against the sagger 10; a first cylinder device 42; and a first crank mechanism 43 for transmitting the thrust of the first cylinder device 42 and moving the abutting portion 41 up and down. As the first cylinder device, for example, a pneumatic cylinder can be used.

As the second cylinder device, for example, a pneumatic cylinder can be used.
Next, the operation of the roller kiln 1 will be described with reference to fig. 3A, 3B to 8A, and 8B. In these drawings, the first to fifth rows of sagger are denoted by symbols 10A, 10B, 10C, 10D, and 10E, respectively.
The sagger 10A to 10E is transported at a low speed by the first roller conveyor 2 in the region 11. At this time, in the region 12, the third roller conveyor 9 on the upstream side is operated at the same speed as the first roller conveyor 2, and the second roller conveyor 3 on the downstream side is stopped.
(First state shown in FIGS. 3A and 3B)
When the sagger 10A is detected by the photosensors 91a, 91b and further by the photosensors 92a, 92b, the third roller conveyor 9 is switched to the high-speed state. The stopped second roller conveyor 3 is also switched to a high-speed state.
(From the second state shown in FIGS. 4A and 4B to the third state shown in FIGS. 5A and 5B)
When the sagger 10A is conveyed by the third roller conveyor 9 and the second roller conveyor 3 and reaches the stopper 4, the sagger 10A is stopped by abutting against the abutting portion 41, and the inclination of the sagger 10A is corrected. Meanwhile, when the sagger 10A is detected by the photosensors 93a, 93b, the second roller conveyor 3 is stopped and the third roller conveyor 9 is brought into a low speed state.
(From the fourth state shown in FIGS. 6A and 6B to the fifth state shown in FIGS. 7A and 7B)
Then, the lifter 5 is lifted to a predetermined height, and the stopper 4 is moved downward, and is moved forward Fang Tuibi from the conveyance direction of the sagger 10A. When the rise of the lifter 5 to a predetermined height and the movement of the stopper 4 to a predetermined retreat position are detected by a detecting device not shown, the sagger 10A is sandwiched from both outer sides in the width direction Y by the width direction position adjusting member 7, and the interval between the adjacent saggers 10A is reduced.
(Sixth state shown in FIGS. 8A and 8B)
After a predetermined time has elapsed, the widthwise position adjustment member 7 moves outward in the widthwise direction Y and returns to its original position. When the widthwise position adjustment member 7 is returned to its original position and the sagger is not detected by the photosensors 94a and 94b, the lifter 5 is lowered. When the lowering of the elevator 5 to the original height is detected by a detecting device not shown, the shutter 80 of the atmosphere replacement chamber 8 is opened, and the second roller conveyor 3 conveys the sagger 10A to the atmosphere replacement chamber 8 at a high speed.
Hereinafter, the same operations as described above are repeated for the magazines 10B to 10E, and the magazines are reliably transported to the next step row by row.
According to the roller conveyor 1 of the present embodiment, the first-row sagger 10A can be separated from the subsequent saggers 10B to 10E by the second roller conveyor 3 capable of switching to the high-speed state having a faster conveying speed than the first roller conveyor 2 before the exit of the roller kiln 1, and the first-row saggers 10A can be aligned by the stopper 4, so that the saggers 10 can be reliably conveyed to the next step row by row.
The present utility model is not limited to the above-described embodiments, and can be appropriately modified within a range not departing from the gist thereof.
