Description

TECHNICAL FIELD The present application relates to a peeling device for laver spread on a cage, and is important when applied to a fully-automatic laver machine.

Conventional technology and problems Circulating a cage frame with multiple cages attached to it, performing the process of dewatering, dewatering and drying the seaweed at a predetermined position, and removing the dried seaweed from the cage as one cycle. The automatic laver machine before continuous repeating is widely known, and it is also the same that various types of laver stripping devices for stripping laver have been proposed. As described above, various types of seaweed stripping devices have been proposed, but in recent years, for example, Japanese Patent Publication No. 58-2542.
As shown in No. 8, No. 61-45826 or No. 63-45195, the perforated belt sucks in the seaweed and peels off both by the action of bending the cage at a steep angle. However, a device for adsorbing the stripped seaweed on a perforated belt and carrying it out of the machine is becoming mainstream. Thus, these conventional devices have a common structure in which the perforated belt that adsorbs seaweed and the suction device that applies a suction airflow to the perforated belt are moved up and down between the standby position and the work position for each work. It has a big defect, the structure becomes complicated, it causes a failure, and there is a problem in maintenance. Further, the first conventional device has a grudge that lacks stability in work because one side of the cage is detached from the cage during stripping of seaweed.
Each of the third and third conventional devices has its own problems such that a plurality of perforated belts are provided in correspondence with the cage and a conveyor belt dedicated to conveyance is required.

Means for Solving the Problems In view of the above-mentioned drawbacks of the conventional device, the present application has a predetermined gap between the guide rail and the guide rail, and a porous member fixed to the machine frame so as to be orthogonal to the advancing direction of the cage frame. A suction conveyance means including a belt and a suction device arranged between the perforated belts, and a guide rail for guiding either the front side or the rear side in the advancing direction of the cage frame sent to a predetermined position. From the surface to the same height as the upper surface of the perforated belt to prepare for peeling, and a vertically movable unit.The preparation means presses the cage from the upper side to the porous belt and stretches the cage to carry out preliminary peeling. And a preliminary stripping means for performing
An upper roller that presses the cage against the perforated belt from the upper side on the side opposite to the preparation means, a lower roller that is located below the cage and holds the cage between the upper roller and the upper roller, and an upper roller and a lower roller. The seaweed is surely stripped by the stripping means constituted by a shifting device that shifts the shell and the shell toward the preparation means side while holding the cage.

Examples Next, the present application will be described in detail with reference to the drawings showing examples. As mentioned above, the fully-automatic laver machine circulates the cage frame to which a plurality of cages are attached, and performs the paper-forming, dehydration, and dry stripping operations at predetermined positions in the circulation path, all of which are well-known.

It is connected by a rod 57, so that the actuation of the cylinder 45 acts on the transition plate 56 via the rod 57. 58 is a transition plate on both sides 56
With a mounting plate mounted so as to bridge between them, a pair of two mounting rods 59 are planted obliquely downwardly corresponding to the cage 4 mounted on the cage frame 1 on the mounting plate 58, and the upper roller 38 is attached to the tip thereof. Rotatably attached. Therefore, the upper roller 38 moves up and down by the vertical movement of the vertical moving plate 49, presses the cage 4 against the perforated belt 10 from the upper side at the time of lowering, and suddenly moves the cage 4 between the lower roller 39 and the lower roller 39 as shown in FIG. Hold it at an angle. In the above embodiment, the cam plate 28 is used as a drive source for each operating portion.
Although the 54 and the cylinders 36 and 45 are used in combination, the drive source may be of any type as long as it can cause each operating portion to perform a desired operation. Reference numeral 59 in the drawing denotes a stay provided between the vertical moving plates 49 on both sides.

Next, the operation of the embodiment of the present invention configured as described above will be described. The dried cage frame 1 is conveyed on the guide surface 6a of the guide rail 6 from the left side to the right side in FIG. 1 by the conveying chain 7, reaches the peeling section 8 and stops, and at the same time, the rotation of the perforated belt 10 also stops. To do. While the cage frame 1 is being conveyed, as shown in FIG. 1, each of the pressing plate 31 and the vertical moving plate 49 rises, the transfer device 40 is located at the most forward end, and the opening / closing plate 20 closes the recessed portion 19. Further, since the lower roller 39 is located on the lower surface of the guide rail 6 as described above, the cage frame 1 does not interfere with the lower roller 39, the conveyance is performed without any support, and the cage frame 1 is stopped. The horizontal rod 2a on the rear side is an opening / closing plate 20
It is placed on the closed surface 20a. When the cage frame 1 stops at the predetermined position as described above, the opening / closing plate 20 in the raised position is lowered by the rotation of the cam plate 28 as shown in FIG. 2, and the rear side rod 2a is recessed. Since the cage 4 falls inside, the rear side descends to a height substantially the same as the upper side of the perforated belt 10 as shown by an imaginary line 4b in FIG. 2 and is stretched obliquely to prepare for peeling work.

When the preparation for stripping is completed, the cylinder 36 is actuated at the timing shown in FIG. 5 to lower the pressing plate 31, pressing the rear side of the cage 4 against the perforated belt 10 and rotating the cam plate 54 to the raised position. The upper / lower moving plate 49 which was located on the upper roller 38
Presses the front side of the cage 4 against the perforated belt 10, and the lower roller 39
Hold the cage 4 at a steep angle between it and this, and the cage 4 on the front side of the place pushed in by the pressing plate 31 is stretched, and the front end portion of the seaweed 5 is stripped from the cage 4. When the cage 4 is entirely in contact with the porous belt 10, the seaweed 5 is adsorbed to the porous belt 10 by the suction airflow. In the above, an elastic pad is provided on the lower surface of the pressing plate
Since the 34 is pasted, the pressing is elastic and does not allow the cage 4 to slip, the cage 4 is stretched securely, and the seaweed 5 is not damaged. Further, the up-and-down movement of the upper roller 38 in the above-described embodiment is an arc movement as is apparent from the drawing, and the mounting rod 59 is obliquely downward,
When the cage 4 is pushed in, the cage 4 is pushed into the lower roller 39 so as to enter the lower roller 39. Therefore, the bending angle of the cage 4 becomes an acute angle, which effectively acts on the peeling operation described later.

Next, the cylinder 45 of the transfer device 40 is actuated, the transfer device 40 at the most forward end is retracted as shown in FIG. 2, and immediately after the operation of the cylinder 45, the cylinder 36 of the preliminary stripping means 29 reverses to the above. The pressure plate 31 which is activated and descends is lifted to release the push-in of the cage 4. When the transfer device 40 is retracted, the upper roller 38 and the lower roller 39 move to the rear side while holding the cage 4 by bending it, so that it is fixed (by suction) from the seaweed 5 as in the case of hand peeling. The cage 4 is peeled off in a pulled-out state, and as shown in FIG. 3, the peeling work is completed at the last withdrawal end, and the seaweed 5 is naturally adsorbed on the perforated belt 10. When the stripping is completed, the cylinder 45 of the transfer device 40 operates in the opposite manner to the above, and the upper and lower rollers 38, 39
Then, the vertical movement device 49 and the opening / closing plate 20 operate in the opposite direction to the above substantially at the same time to raise the upper roller 38 to the old position, and the opening / closing plate 20 falls in the recessed portion 19. The rear side rod 2a is pushed up by the closing surface 20a to rise, and the concave portion 19 is closed to prepare for the next transfer of the cage frame 1, and the vertical movement device 49 and the opening / closing plate 20 are stopped substantially at the same time. The perforated belt 10 restarts its rotation and conveys the seaweed 5 peeled off from the cage 4 and adsorbed to the next process, and the transport chain 7 is operated for a moment from these operations, and the next cage frame is operated. 1
Is transferred to the peeling section 8 and this is used as one cycle for continuous work. In the above embodiment, the preliminary stripping means 29
Is a so-called safety device for 100% peeling regardless of the hardness and thickness of the seaweed 5 due to changes in the properties of the seaweed alga and other working conditions, and is not always essential. Further, in the above, the concave portion 19 and the preliminary peeling means 29 are attached to the cage frame 1
Although the upper and lower rollers 38, 39 are provided on the front side on the rear side in the advancing direction, they may be provided on the opposite side to the drawing.

EFFECTS OF THE INVENTION As described in detail above, according to the present invention, the lower surface of the guide rail is fixedly provided with a suction conveying means so as to be perpendicular to the lower surface of the guide rail so as to be orthogonal to the advancing direction of the cage frame. By making the rollers move forward and backward in the horizontal direction through this gap, the vertical movement of the suction conveyance means is eliminated, and not only the reliable peeling work can be performed with an extremely simple device compared with the conventional device, but also the peeling work. Since the operation is the same as in the case of manual stripping, the seaweed is not damaged, and the transportation to the subsequent process is smooth and reliable.
