JPS5957813A - Method of detecting and taking out dried laver on approaching and device therefor - Google Patents

Abstract

PURPOSE:To aim at preventing entanglement and damage of dried lavers, by providing such an arrangement that there are provided along a dried laver conveying path, a plurality of detectors whose detection signals in combination are used to determine the condition of the dried lavers on approaching so that a take-out device is actuated when the condition of the lavers is normal. CONSTITUTION:The passing of lavers which are transferred at intervals of a predetermined space on a conveying path 4 is detected by photo-electric switches 6a through 6d of transmitted light detecting type, which are arranged at intervals of a predetermined space along the conveying path 4. That is, upon deenergization of all switches 6a through 6d, a variable conveying path 7 ascends since no lavers are present, and is maintained to be flush with the conveying path 4. However, when the intervals of the transferred lavers are improper, the plurality of the photo-electric switches 6a through 6d are energized, simultaneously, and issue signals which are used, in combination, for discrimination, so that the variable conveying path 7 descends to transfer the improper lavers into an approaching levar storing box 17. With this arrangement in which the intervals of the photo-electric switches 6a through 6d are properly set, the suitable intervals of the lavers are maintained, thereby entanglement and damage of the lavers are prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and an apparatus for detecting and removing approaching dry seaweed, which detects the distance between dried seaweed being conveyed from one place to another, and removes dry seaweed that is closer than a predetermined distance to the outside of the conveyance path.

In recent years, the production of dried seaweed has become fully automated, and the production capacity is about 2,500 to 8,500 sheets/hour, and there is a tendency for the production speed to be further increased.

When bringing the manufacturing machine and sorting machine online, appropriate timing of the supply of dried seaweed from the ashore is an essential condition. In other words, regardless of whether the interval between consecutively supplied dried seaweed is longer than the predetermined interval, if it is shorter, the next dry seaweed will be processed before the previous dry seaweed has been processed (sorting the good and bad ones is done). There is a drawback that the seaweed sorting machine does not function satisfactorily when dried seaweed arrives or when two sheets of dried seaweed are already overlapped.

The present invention has been made in consideration of the above points.

f! Ilf,% Multiple detectors are installed on the transport path of seaweed, and the combination of signals generated from these detectors detects the approach of transported dried seaweed and determines whether a predetermined distance is maintained. When dried seaweed is closer than a predetermined distance, the approaching dry seaweed is removed from the conveyance path. A dry seaweed removal device is installed at the rear of these detectors, and the approach of the transported dried seaweed is sensed by a combination of signals generated from these detectors, and the removal device installed on the transport path is activated to remove the approaching dried seaweed from the transport path. The object of the present invention is to provide a detection and extraction device for approaching dry seaweed.

An nJ variable feed path that swings in one direction “centering on 18” is extended from the transport path 4, and a transport heald 10 is installed between the tip of the swing arm 81 and the roller 9 provided on the frame 1. It has been set up. One end of the unloading rod 11 is attached to the swinging arm 81, and the end of the unloading rod 11 is biased to the rotating wheel 12 provided on the frame 1, and is rejected by the rotating wheel 12. is driven from a timing clutch 13 attached to the frame 1 via a chain j4, and the timing clutch 13 is operated intermittently by a solenoid 15.

Reference numeral 16 denotes a holding belt for suppressing the movement of seaweed, which follows the movement of the variable conveyance path 7.

Next, to explain the present invention in detail, when the dried seaweed A is conveyed on the conveyance path 4 with a predetermined interval or more, the variable conveyance path 7 becomes the same 3V-plane as the conveyance path 4. Dried seaweed A is transported to a seaweed inspection device (not shown), but if the distance between the dried seaweed A is closer than a predetermined distance or overlaps, JLσ generated from the photoelectric swigs 5a161+ and 66.6d, respectively. ) is detected by a combination of signals, and the solenoid 1 is detected through a side leg device (not shown).

The elevator rod 11 is pulled down via the shaft 12 to lower the ++J-transfer conveyance path 7, and the approaching dry seaweed A is taken out into the approaching seaweed storage box 17 provided at the lower part of the frame 1.

After removing the approaching dry seaweed A, the solenoid 15 is activated to again make the variable transport path 7 flush with the transport path 4 and transport the dry seaweed A to the seaweed inspection device.

In the present invention, since the relationship between the operation of the photoelectric switches 5a and 6b16cq6d and the operation of the variable conveyance path 7 is a small characteristic, this point will be revised and explained in more detail. In the present invention, when none of the photoelectric switches 6, a, 6b, 6o, and 6d operate, the photoelectric switches 5, 6a, and 6a switch between the photoelectric switches 5, 6a, and 6a. jy
The fifth path 7 is on the same plane as the conveyance path 4.

Dried seaweed A that the C variable conveyance path 7 is descending and approaching
is removed in the following cases.

(1) When the dried seaweed A1 and A2 are in the state shown in FIG. (The photoelectric switch 6b does not operate until it has passed a predetermined distance through the photoelectric switch 6b, and after the photoelectric switch 6b has passed the predetermined distance, it emits light.) In this case, dried seaweed A1 is sent as is to the seaweed inspection device;
After the dried seaweed A1 has passed through, the variable conveyance path 7 descends, so that the dried seaweed A1 is sent into the approaching seaweed storage box 17.

(2) If the dried seaweed A1 and A2 are in the state shown in Figure 3, that is, if they are close to each other or overlap and the photoelectric switches (ia, 5b, 6c) are in the ON state, only the close dried seaweed A2 is removed. Since it is impossible to
When the dried seaweed is approaching, it is sent into the dry seaweed storage box 17.

(3) When the dried seaweed A1 and A2 are in the state shown in FIG. 4, that is, when the photoelectric switches 6a and 6d are in the ON state due to light shielding, and the photoelectric switch 6b (3a is in the transmitting state and OFF), the dried seaweed AI is in the photoelectric switch 6d. When the light enters the transparent state, the variable conveyance path 7 descends and the dried seaweed A2
is transported to the approaching dry seaweed storage box 17.

Note that if some abnormality occurs in the seaweed inspection device connected to the device according to the present invention and it is desired to stop the dried seaweed A from being conveyed to the seaweed inspection device, the variable conveyance path 7 may be lowered artificially. Furthermore, when the control device of the device according to the present invention is connected to the photoelectric switch of the inspection device connected to the rear of the device according to the present application, and this photoelectric switch is in a dark state for a long time for some reason (if the dry seaweed is It is also possible to set the variable conveyance path 7 to descend even when the conveyance path 7 remains in place due to a cause.

wAs explained above, in the present invention, a plurality of detectors are provided on the transport path of the seaweed, and the approach of the seaweed is sensed by a combination of the signals generated from the detectors, and the take-out device provided on the transport path is activated. Since the seaweed is taken out from the conveyance path, the seaweed sent to the device that will be connected later is sent at intervals that match the operating timing of the machine, which prevents the seaweed from becoming entangled and being damaged. It is essential for sorting machines.
