Description

[Detailed Description of the Invention] Industrial Application Field The present application relates to a frame transfer mechanism, and more particularly, to a frame transfer mechanism between a papermaking device and a drying chamber in an automatic seaweed manufacturing apparatus.

Conventional technology In order to shorten the total length of automatic seaweed production equipment, reduce the installation area, and improve the quality of the drying chamber and seaweed, we installed two drying chains in the upper and lower stages inside the drying chamber. Devices for transferring screen frames between the two are already well known. In the above-mentioned conventional method, the delivery, that is, the transfer of the screen frames was carried out at the respective delivery locations by separate delivery mechanisms. Therefore, in the case of the above conventional device,
Transfer from the papermaking device to the upper drying chain in the drying chamber, the drying chain below this chain, and the further lower drying chain to the papermaking device again, and each of the transfer points between the three different types of devices. Requires a delivery mechanism at the location.

Problems to be Solved by the Invention As described above, in the conventional device, a delivery mechanism is provided at each delivery point, which not only makes the overall structure of the device extremely complicated, but also involves the need for these delivery mechanisms and papermaking devices, etc. It is necessary for the operating parts to perform accurate synchronous operation, and this adjustment work is difficult and there is a drawback that timing errors are likely to occur during the work.

Means for Solving the Problems In view of the above, the present application proposes a transfer chain with claws for transferring a paper frame that circulates through a papermaking device in which a papermaking section, a dewatering section, and a stripping section are provided. By using the section between the dewatering section installed on the road and the stripping section also installed on the return road to transfer between the three types of devices mentioned above, the drawbacks of the conventional devices described above can be overcome with a simple configuration. It is excluded.

Function: The transfer chain that circulates through the paper-making equipment transports the paper-making process in the paper-making section and the cage frame with the cage attached, which is dehydrated in the dewatering section, to the drying chain above the drying room. and the handing over operation.
All of the operations of receiving the dried frame frames by the upper chain, transferring the frame frames received from the upper drying chain and transferred downward to the lower drying chain, and receiving the dried frame frames again by the lower drying chain. At the same time, the screen frame is transferred to the peeling section and the dried nori is peeled off from the screen.

As described above, in the present application, a part of the transfer chain is used to transfer the screen frame between three different types of devices without using a separate transfer mechanism, so the rotation timing of the transfer chain can be adjusted. Perfect synchronization can be easily achieved by simply synchronizing the upper and lower drying chains.

Embodiments The present application will be described in detail below with reference to drawings showing embodiments.

In Fig. 1, reference numeral 1 indicates a pair of transfer chains with claws (hereinafter referred to as transfer chains), with a predetermined interval (second
A pair of pawls 3 are provided for each length of the screen frame 2 shown in the figure plus α), and are suspended from a large number of sprockets S and SA to form endless transfer paths E and C, not shown. As is well known, the papermaking apparatus M is constructed by disposing a papermaking section, a dewatering section, and a peeling section at predetermined locations of the endless transfer paths E and C. The transfer chain 1 in this embodiment has sprockets S shown at points A and C.
and on the sprocket S shown at points B and D, so that the screen frame 2 is delivered between the upper drying chain 4 and the lower drying chain 4A, which will be described later, and at points B and C. In between, a part of the transfer chain 1 serves as a transfer path 5 for the screen frame 2 between the upper and lower drying chains 4, 4A.
As shown in FIG. 2, the screen frame 2 has a front frame rod 6 and a rear frame rod 7 connected in a ladder-like manner by a connecting rod 8, and a screen 9 is attached by an appropriate means such as a clip. The rod 6 is set to be longer than the rear frame rod 7.

The upper and lower drying chains 4, 4A have the same structure as the conventional one, and each link of the pair of endless chains 10, 10A suspended between the sprockets S1 includes a screen frame holding rod 11 that holds and transfers the screen frame 2. are installed in the drying chamber in two stages, upper and lower, so that the screen frame 2 is transferred to and from the transfer chain 1 at each of the above-mentioned points, and the lower transfer section of both drying chains 4 and 4A is installed. Transfer rails 13 and 13A are attached to 12A and 112A, respectively. Note that the drying chamber is a conventionally well-known structure consisting of a box housing the drying chains 4, 4A described above, a hot air supply device, etc., and is therefore not shown in the drawings. Reversing device 14
is provided in the middle of the transfer path 5 between both drying chains 4 and 4A, and is constructed as follows. Reference numeral 15 denotes a pair of reversing rails, and the reversing rails 15 receive and place the rear frame bars 7 of the screen frame 2 transferred through the transfer path 5, and as the screen frame 2 is transferred, the frame bars 7 It is inclined so as to be guided obliquely downward while being kept away from both drying chains 4, 4A. Reference numeral 16 denotes a reversing guide rail, which is installed below the reversing rail 15 with an inclination in the same phase and direction as the reversing rail 15, and its upper and lower ends are set to be longer than the reversing rail 5. It is bent into a ``'' shape, and the bent portion is directed toward the lower drying chain 4A. 17 is a pair of guide rails that receive and guide the rear frame rod 7 during transfer, and 18 is a guide roller provided coaxially with the sprocket SA.
Both act to smoothly guide the rear frame rod 7 to the reversing rail 15.

In addition, 14A in the figure is a reversing device that reverses the screen frame 2 taken over from the lower drying chain 4A to the transfer chain 1 before reaching the nori peeling device (not shown), and the reversing rail 15A and It is the same as above except that the inclination direction of the reversing guide rail 16A is opposite to the reversing device 14.

The front frame rod 6 of the cage frame 2 is locked to the claw 3 of the transfer chain 1, and the frame frame 2 is transported back and forth in the clockwise direction in FIG. The screen frame 2 that has been removed is transferred toward the drying room to the delivery position of the screen frame 2 shown at point A, and at this point, the screen frame 2 is held between the screen frame holding rods 11 of the upper drying chain 4 and delivered. The drying chain 4 that has taken over the screen frame 2 reciprocates and circulates the screen frame 2 in a drying chamber (not shown), and transfers the screen frame 2 to the delivery position to the transfer chain 1 shown at point B. As is clear, when the screen frame 2, which has been delivered by inserting the front frame rod 6 of the screen frame 2 between the screen frame holding rods 11, is transferred through the upper transfer section 12, the front side frame rods 6 are inserted between the screen frame holding rods 11. It becomes the lower side of the frame 2, and reaches the lower transfer part 12A and becomes the upper side. That is, the top and bottom (top and bottom) of the screen frame 2 are reversed during transportation. When the screen frame reaches the lower transfer section 12A, the front frame rod 6 is placed on the transfer rail 13 to prevent the screen frame 2 from falling off between the screen frame holding rods 11.

The screen frame 2 that has been transferred to point B as described above is delivered again at this point with the front frame rod 6 being locked between the claws 3 of the transfer chain 1, and the transfer chain that took over the screen frame 2 is The screen frame 2 is transferred from the upper drying chain 4 to the lower drying chain 4A by the transfer path 5 constituted by the transfer chain 1. During the transfer, the screen frame 2 is transferred as follows. can be reversed. That is, the transfer chain 1 that has taken over the screen frame 2 at point B locks the front frame rod 6 between the claws 3, and the screen frame 2 first moves the transfer path 5 to the position shown at point P in the hanging state. It is transferred diagonally downward, but on the way, the rear frame rod 7 is moved to the guide rail 1.
7, the rear frame rod 7 is connected to both drying chains 4,
4A (left side in the drawing), and as the screen frame 2 is further transferred, the rear frame rod 7 passes through the guide roller 18 and is placed on the reversing rail 15, and at point P, as shown in the drawing, In addition, the rear frame rod 7 is guided diagonally downward by the reversing rail 15 in a direction away from both drying devices 4, 4A, and is inclined, so that it is in a half-inverted state.
When the storage frame 2 is obliquely transferred along the transfer path 5 to point P, the transfer rail 13 prevents the front frame rod 6 from falling off from the claws 3.

The screen frame 2 that has been transferred to point P as described above is then transferred to the position shown at P1.
5 further diagonally downward, and finally falls from the lower end of the reversing rail 15 to the reversing guide rail 16 provided below and is caught, and when the cage frame 2 is transferred to point P1, the front side The frame rod 6 is reversed so that it is on the front side with respect to the direction of movement of the transfer chain 1. As is clear from FIG. 1, the reversing rail 15 and the reversing guide rail 16 place only the rear frame rod 7 of the screen frame 2, and the position of the reversing rail 15 is the second one.
As shown in the figure, since the connecting rod 8 is provided so as to place the part that protrudes outward, the rear frame rod 7 is moved from the reversing rail 15 to the reversing guide rail 1.
6, and when the screen frame 2 is further transferred to point P1, the screen frame 2 and the reversing rail 15 are smoothly reversed and transferred without interference. Also, when the screen frame 2 is transferred to point P, the screen frame 2 that precedes it is
The rear frame bar 7 of the screen frame 2 at the P point is held by the reversing rail 15, so there is no interference between the two, and in order to perform the reversing operation, the claw 3
There is no need to change the design to lengthen the installation interval, and there is no reduction in work efficiency.

The screen frame 2 that has been transferred to point P1 and has been reversed is then transferred to the delivery position of the lower drying chain 4A shown at point C, and the screen frame 2 is delivered at the same time as the above point A, but as is clear from the drawing, the screen frame 2 is not transferred. The front frame rod 6 of the screen frame 2 is on the lower side when being transferred through the upper transfer path 112 of the lower drying chain 4A, and naturally becomes on the upper side when reaching the lower transfer path 112A. That is, in the present application, when the screen frame 2 that is dried while being reciprocated and circulated through both drying chains 4 and 4A is viewed from the front frame rod 6 held between the screen frame holding rods 11 as a reference,
"Lower" in the upper transfer path 12 of the upper drying chain 4, "upper" in the lower transfer path 12A, "lower" in the upper transfer path 112 of the lower drying chain 4A, and "lower" in the lower transfer path 112a of the lower drying chain 4. is "above"
The top and bottom of the screen frame 2 are alternately switched for each transfer path, and the drying process is performed, and at point D, the screen frame 2 is transferred to the transfer chain 1 again.

The transfer chain 1 transfers the taken-up cage frame 2 to a nori peeling section (not shown) and performs the nori peeling work, but in the middle of the process, the reversing device 14A turns the nori frame 2 so that the surface on which the seaweed is spread is on the lower side. Although it is reversed again, the reversing operation by the reversing device 14A is
Everything is the same except that the direction of reversal is opposite to the direction of reversal by the reversing device 14. Also, while the cage frame 2 is transferred from the lower transfer path 4A to the transfer chain 1 and transferred to the nori peeling device via the reversing device 14A,
The transfer rail 13A holds the upper frame rod 6 to prevent the cage frame 2 from falling off, as described above.
Further, the cage frame 2 from which the seaweed has been peeled is transferred again to the papermaking section (not shown) by the transfer chain 1, as in the conventional case.

In the above embodiment, the transfer of the screen frame 2 between the transfer chain 1 and the upper and lower drying chains 4, 4A is carried out at point A on the upper side, point C at point B on the lower side, and
Although this is done at different locations at point D, this does not limit the technical idea of the present application; sprockets of the same diameter are placed opposite each other on the left and right in the drawing, as is conventionally widely done, and an endless sprocket is placed between them. chain 1
0 and 10A may be suspended to form a drying chain 4 and 4A, and delivery may be performed at two different locations on the same sprocket. In this case, the height of the drying chamber can be reduced.

Effects As detailed above, the present invention provides a method for transferring the frame between the transfer chain and the upper and lower drying chains, that is, between three different types of devices, by circulating the frame within the papermaking device and reciprocating the frame. A dewatering section provided on the outbound path to the drying room of the transfer chain for conveying and circulating;
Similarly, by using the space between the stripping section provided on the return path, the structure is not only much simpler than that of conventional equipment that has a separate delivery mechanism, but also allows for a transfer chain and upper and lower drying chains. Since synchronized rotation has been performed in the prior art, it has the advantage that perfect synchronization can be easily obtained without taking special tuning means when implementing the present application.
