Description

  The present invention relates to a laver direction changing apparatus. That is, the present invention relates to a laver direction changing device provided between a drying device and a next process in a laver production line.

《Technical background》
In the production line of dried seaweed (hereinafter simply referred to as seaweed), first the raw seaweed plucking, water washing, paper making, dehydration, drying, etc. are followed, and then inspection, bundling, alignment, folding, binding, accumulation, etc. By following each process, laver is produced.
And the drying apparatus of a drying process is remarkably large-sized for the improvement of production efficiency, and the weight with respect to the whole space which has a limited production line is increasing.
Therefore, in the laver production line, as shown in FIG. 4 (1), the direction in which the laver A is immediately transported in an orthogonal cross from the drying apparatus 1 to the next process apparatus, for example, the sorting inspection apparatus 2, is changed. The development and practical application of the device 3 have been desired.

That is, laver A that is unloaded from the drying device 1 and is loaded with the surface side facing up is immediately turned 90 ° from the loading direction B to the unloading direction C by the direction changing device 3. If it can be carried out to the inspection apparatus 2, it will be possible to prevent an increase in the total space of the production line for laver A.
As shown in FIG. 4 (1), if the inspection device 2 and other next process devices arranged in parallel can be arranged adjacent to the drying device 1 in parallel, there is no waste of production line space. The production line can be contained within the limited total space.
For example, the drying apparatus 1 and the inspection apparatus 2 and other next process apparatuses can be arranged in a substantially H-shaped or letter-shaped form that does not take up a space, for example, in a wide space. The development and practical application of the direction changing device 3 have been desired.

<Conventional technology>
FIG. 3A shows a conventional example of such a direction changing device 4. In this direction changing device 4, a curved belt conveyor 5 is adopted, and the curved belt conveyor 5 rotates in an arc shape while being guided by the inner and outer guide portions 6 and 7, so that the laver A is moved from the loading direction B. Transport in the carry-out direction C while sucking and holding.
Therefore, the laver A carried in from the drying device 1 is turned 90 ° and carried out to the inspection device 2 and other next process devices.

FIG. 3 (2) shows a head elimination device 8 provided between the drying device 1, the inspection device 2, and other next process devices as a reference example of the prior art.
This head elimination device 8 is premised on a method in which laver A is carried out from the upper part of the drying device 1. The laver A carried in from the uppermost carry-in conveyor 9 of the apparatus is sequentially conveyed from the upper apparatus to the lower apparatus by the rotating drums 10 and 11 and the guide conveyors 12 and 13, thereby bringing out the lowermost conveyer 14 in the apparatus. Then, it is carried out to the next process equipment.
At this time, as a result, the drop elimination device 8 has a relationship in which the carry-in direction B by the carry-in conveyor 9 and the carry-out direction C by the carry-out conveyor 14 cross each other at right angles. The laver A that has been carried in is turned 90 ° and carried out.

Such prior art is disclosed in the following Patent Documents 1 and 2, for example.
JP 2005-255315 A JP 2005-0275547 A

By the way, the following problems have been pointed out with respect to such conventional techniques.

That is, in the production line of laver A, laver A that is successively carried in from the drying device 1 with speed is sequentially changed by the curve belt conveyor 5 and carried to the inspection device 2 and other next process devices. In doing so, the possibility of an accident was pointed out.
For example, there is a risk that the laver A that is being sucked and being changed in direction is affected by the centrifugal force due to the rotation of the arc of the curve belt conveyor 5 and is displaced, overlapped, or dropped. The direction change of laver A tends to become unstable, and anxiety has been pointed out especially at a high speed.

<< Second problem >>
Next, a reference example of the prior art shown in FIG. 3 (2) and Patent Document 2 is as follows. First, the head elimination device 8 is premised on a method in which the laver A is carried out from the top of the drying device 1 in the laver A production line. It is difficult to apply to the method in which the laver A is carried out from the lower part of the drying device 1. This drop elimination device 8 is a dedicated machine for eliminating a height difference of about 0.6 m, for example, leading the laver A from the upper level to the lower level.
Therefore, the installation height is high and the size is increased, and the installation of the inspection apparatus 2 and other post-process apparatuses may have an adverse effect on the high / low balance.

  (2) The laver A carried out is carried into the direction changing device 15 in the straight carrying-in direction B. That is, the carry-in conveyor 19 positioned at the lowest position of the direction changing device 15 carries the laver A with the front side facing up and the back side facing down and the long side facing the carry-in direction B (FIG. 1). , See FIG.

  (3) The laver A carried in by the carry-in conveyor 19 is sent by the first rotating drum 16 to the second rotating drum 17 located right above with a slight interval. Both the rotating shaft 23 and the rotating shaft 22 are horizontally, parallelly, and rotated in the same direction (see FIGS. 1 and 2 (1) and (2)).

(4) And the laver A is sent from the second rotating drum 17 to the third rotating drum 18 on the side (see FIG. 1).
In the third rotating drum 18, the rotating shaft 21 obliquely intersects with the rotating shaft 22 of the second rotating drum 17 by 45 ° and also in the unloading direction C of the unloading conveyor 20 by 45 ° (see FIG. (See Fig. 2 (3) and (4)).

(5) Then, the laver A is sent from the third rotating drum 18 to the carry-out conveyor 20. The carry-out conveyor 20 carries out the laver A toward the straight carry-out direction C crossing the straight carry-in direction B (see FIGS. 1 and 2 (4)).

  (8) Therefore, according to this direction changing device 15, it becomes possible to change the direction of the laver A that is continuously sent with speed in a stable manner. Compared to the case of changing the direction by using the curved belt conveyor 5 (see the prior art in FIG. 3 (1)), the direction can be changed without causing an accident.

  (9) Moreover, this direction change apparatus 15 makes seaweed A carried out from the lower part of the drying apparatus 1 into carrying in object. And while carrying in this with the carrying-in conveyor 19, the laver A which changed direction is carried out by the carrying-out conveyor 20 to next process apparatuses, such as the inspection apparatus 2. FIG.

(10) During this time, the height difference of the laver A before and after the direction change, that is, the height difference between the conveyors 19 and 20 is very small, for example, about 110 mm (for example, in the conventional technique of FIG. . Height difference of about 6m).
In this way, the direction changing device 15 can carry in and out with almost no height difference. That is, laver A is once raised from the lower carry-in conveyor 19 to the first rotary drum 16 and the upper second rotary drum 17 and then from the upper third rotary drum 18 to the original lower-level carry-out conveyor. You are lowered to 20.
