Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a nori-covered cage installation device for attaching a nori-covered cage (hereinafter referred to as an attachment cage) to a cage mounting frame of a dryer after a dewatering process, which grips a sealed tube. The allocation of the screen gripping device to the left and right is related to the movement device.

The dryer's screen mounting frame is horizontally long so that multiple sealed tubes can be installed horizontally side by side, and the trimming protrusions provided between adjacent pipe mounting positions on this screen mounting frame correspond to the width of the dryer. (In order to make it narrower, the mounting position for both pipes is shared.

Therefore, when attaching sealed tubes to the screen mounting frame, it is not possible to attach the sealed tubes to adjacent screen mounting positions at the same time, but the tubes must be installed one after another so that the ends of the tubes overlap.

In addition, the protrusions of the trimmings on each screen mounting frame of the dryer are designed to prevent them from interfering with the protrusions on the successive screen mounting frames, and to reduce the mounting pitch of each screen mounting frame to the rotating chain. Slightly horizontally on every other mounting frame (generally 8rIt
11).

Therefore, when attaching a sealed tube to a screen mounting frame, it is necessary to change the mounting position for each screen mounting frame.

Furthermore, when attaching the sealed tube to the screen mounting frame, accurate positioning is required because the sealed tube is covered with seaweed and only a few hooks remain.

For the reasons mentioned above, the attachment of sealed tubes to the screen mounting frame of a dryer has conventionally been done one by one manually, and automation of this work has been desired.

Therefore, research has been progressing in recent years on methods and devices for automatically attaching the sealed tube to the screen mounting frame, and the present invention also relates to a series of automated devices.

Even when the screen mounting positions of the screen mounting frames in a dryer are slightly shifted from every other screen mounting frame, the present invention allows the screen mounting positions of the screen mounting frames to be adjusted to correspond to the mounting positions of the screen mounting frames. The purpose of this invention is to provide a moving device for the sorting of the screen gripping device in the seaweed sealed tube mounting device, which is capable of reliably and stably moving the screen holding device toward the screen mounting position.

The roller 90 attached to the crankshaft 88 interferes with the push-up piece 91 fixed to the crankshaft 28 and is pushed up every time the crankshaft 28 rotates.
The structure of this push-up device 87 is not a feature of the present application, so a detailed explanation will be omitted.

Next, the operation of the above configuration will be explained.

When the sealed tubes 6 that have completed the dehydration process are placed one by one on the conveyance roller 1 by an automatic chopstick supply device (not shown), they are conveyed horizontally and shifted to one side by 10 rotations of the conveyance roller, and then the stop plate 7 and is stopped at a predetermined gripping standby position.

The conveyance of the sealed tube 6 to the gripping standby position is carried out by the crankshaft 28.
This is carried out at a good timing while the carriage 19 is moved forward by the rotation of and the push-up device 87 is in the lowered position.

Thereafter, the carriage 19 is moved backward by 280 rotations of the crankshaft, and the horizontal rollers 22 of the carriage 19 abut against the stopper bolts 35, so that the carriage 19 is stopped at the rearmost position.

At this time, the cage gripping device 43 is positioned exactly downward as shown in FIG. 2, and is opposed to the sealed tube 6 in the gripping standby position.

This carriage 19 is stopped by the 7 per bolt 35.
The crankshaft 28 is rotated just before the rear dead center of the crank 29, and the spring 34 of the connecting rod 30 is compressed until the crank 29 reaches the rear dead center.

Therefore, the carriage 19 is slightly opened and stopped at the rearmost position,
During this time, the sealed tube 6 in the gripping standby position is gripped by the cage gripping device 43 in the following manner.

That is, as the crankshaft 28 rotates, the push-up piece 91 interferes with the roller 90 of the lifting rod 88 and raises the entire push-up device 8γ by a predetermined amount, whereby the push-up device 8γ lifts the sealed tube 6 at the gripping standby position as shown in FIG. The screen gripping device 43 is pushed up to the gripping position shown by the imaginary line to securely grip the tube gripping device 43 while the sealed tube 6 is stopped.

After gripping the sealed tube 6, the crankshaft 28
The push-up piece 91 is removed from the roller 90 by zero rotation, and the push-up device 87 is returned to the standby position by falling under its own weight.

Thereafter, the rotation of the crankshaft 28 causes the swinging arm 23 to move to the second position.
In the figure, the carriage 1 is swung counterclockwise.
9 is moved forward, and the screen gripping device 43 attaches the sealed tube 6 it is holding to the screen mounting frame 54 of the dryer as shown below.

In this case, the screen mounting frame 54 at the mounting position in the dryer is shifted to the right as shown in FIG. 1, and the screen mounting frame 54 one position before the mounting position is shifted to the left. It's shifted.

Then, the screen mounting frame 54 one position before this engages with the detection arm 84 of the detection device 79 to operate it, and the driven arm 85 pulls the wire 77b and swings the locking lever 75 to the locking position. It's moving.

Therefore, as shown in FIG. 1, the displacement lever 67 of the displacement means 66 is locked and held at the position where it is swung backwards against the spring 68, and the cam plate 12 is swung rightward. There is.

When the carriage 19 is moved forward in this state, the cam follower 53 of the lever 48 comes into contact with the switching plate 14 midway through the movement and is guided into one of the cam grooves 13.
As a result, the lever 48 is swung for five distributions to the left as in the states shown in FIGS. 1 to 3.

This distribution is done by swinging the lever 48, which moves the support shaft 3γ to the left via the drum 42 and the roller 52, and at the forward end position of the carriage 19, the screen gripping device 43 is moved to the dryer. The support shaft 37 is moved to a position corresponding to one of the screen mounting positions of the screen mounting frame 54 at the mounting position.

This movement of the support shaft 37 is carried out extremely smoothly since the support shaft 37 is supported by a roller bearing 41 consisting of a bearing 40 so as to be movable left and right.

Further, when the carriage 19 is moved forward, the roller 59 of the turn converter 57 in the turn plate cutting wedge means 56 comes into contact with the left abutment surface 64, and as shown by the imaginary line in FIG. This state is held by the notch 65.

Furthermore, when the carriage 19 is moved forward, the lever 45
The engagement roller 46 is guided by the plate cam 47 and swung as shown by the imaginary line in FIG. The screen gripping device 43 is swung approximately 90 degrees to hold the screen mounting frame 54.
is placed opposite to one of the screen mounting positions, and is moved forward in this state.

Then, at the forward end position of the carriage 19, the screen gripping device 4
3 inserts the gripped sealed tube 6 into the protrusion 55a of the screen mounting frame 54 and attaches it to the screen mounting position.

Due to the subsequent rotation of the crankshaft 28, the carriage 19
is moved backward, and as a result of this backward movement of the carriage 19, the screen gripping device 43 is swung downward while being regulated by the plate cam 47 due to its own weight, and the lever 48 is swung rightward to support the distribution. The shaft 37 is returned to the original intermediate position, and as a result, the cage gripping device 43 is returned to its original position at the retreating end position of the carriage 19, and the tube gripping device 43 is returned to its original position to pick up the next sealed tube from the gripping standby position that has been conveyed up to this point. 6 is faced.

Further, when the carriage 19 is moved backward, the switching piece 62 integrated with the turning converter 57 enters the left side of the engagement pin 63 near the retreating end, and the roller 59 is guided by the guide surface 61 and turns. When the converter 57 is returned to the neutral position, the switching piece 6
2 contacts the engagement pin 63 and causes it to swing, thereby switching the switch plate 14.

After that, the next sealed tube 6 is gripped by the cage gripping device 43, and the carriage 19 is moved forward again, but this time, the distribution is done by lever 4.
The 8 cam follower 53 is guided into the other cam groove 13, and the lever 48 is swung to the right.

Therefore, the screen gripping device 43 is moved to the other screen mounting position of the screen mounting frame 54 as shown by the imaginary line in FIG. Have them wear it.

Further, when the carriage 19 is moved forward, the roller 59 of the turning converter 57 comes into contact with the contact surface 64a and is swung counterclockwise during the forward movement.

In this case, the displacement lever 67 of the displacement means 66 is held in a locked state by the locking lever γ5, and the cam plate 12 is displaced to the right.

Thereafter, the carriage 19 is moved backward again, but this time the switching piece 62 of the switch plate cutting wedge means 56 enters the right side of the engagement pin 63, swings the engagement pin 63, and moves the switch plate 14. Switch.

Accordingly, the switch plate 14 is returned to the initial position, and in the next forward movement of the carriage 19, the lever 48 is shifted to the left.

After that, the carriage 19 repeats the back and forth movement as described above, but before the carriage 19 is moved forward next time, the rotary chain 92 of the drain tray mounting frame 54 rotates in the dryer by -pitch. be done.

Due to this rotation of the rotation chain 92, the screen mounting frame 54, whose screen mounting position is shifted to the left, is positioned at the mounting position.

Also, the screen mounting frame 54 at the mounting position. The screen mounting frame 54 that is one position closer to the screen changes to one in which the screen mounting position is shifted to the right.

Therefore, the detection arm 84 of the detection device 79 is disengaged from the screen mounting frame 54 due to the rotation of the rotation chain 920, and the tension on the wire γlb is released. is swung back to the open position by the spring 76.

In this state, the screen mounting position of the next screen mounting frame 54 is shifted to the right and this screen mounting frame 54 does not rotate the detection arm 84, so it is held until the rotation chain 92 is further rotated by -pitch. be done.

Next, when the carriage 19 is moved forward, the displacement lever 67 of the displacement means 66 is swung forward by the spring 68 and comes into contact with the stopper 69, and from this K the cam plate 12 is moved to the left. is slightly oscillated.

Therefore, the above-mentioned distribution of the screen gripping device 43 is such that the movement position is displaced to the left by the amount M of the screen mounting position of the screen mounting frame 54, and as a result, the screen gripping device 43 is moved to the left side by the amount M of the screen mounting position of the screen mounting frame 54. It is accurately moved to the position corresponding to the screen installation position,
The gripped sealed tube 6 is securely attached to the screen mounting position.

After that, when the carriage 19 is moved backward, the engagement piece 74 engages the engagement roller 72 and swings the displacement lever 67 backward, but since the locking lever 75 is located at the open position, When the reciprocating carriage 19 is subsequently moved forward again without locking the displacement lever 67, the displacement lever 67 is also swung forward.

Therefore, by the subsequent back and forth movement of the carriage 190, the screen gripping device 43 accurately attaches the sealed tube 6 to the other screen mounting position of the screen mounting frame 54.

Thereafter, until the carriage 19 is moved forward again, the rotation chain 92 of the screen mounting frame 54 in the dryer is rotated by a pitch, so that the screen mounting frame 54 is engaged with the detection arm 84 of the detection device 79. At the same time, they are rotated and the wire 77b is pulled to position the locking lever 75 at the locking position, thereby locking and holding the displacement lever 67 in the rearwardly swung position.

Note that if the locking lever 75 swings to the locking position before the displacement lever 67 swings backward, the engagement shaft 73 of the displacement lever 67 will move toward the tip of the locking lever 75. The engagement lever 75 is pushed back against the spring 18 by contacting the slope of the engagement shaft 73, whereby the engagement shaft 73 is engaged with the engagement portion 75a.

By sequentially repeating the operations described above, the sealed tube 6 is automatically attached to the screen mounting frame 54 of the dryer.

FIG. 5 shows a second embodiment of the distribution and displacement means, in which a solenoid 93 for swinging the locking lever 75e against the spring γ6e is provided on the base plate 9e, and a limit switch is used as a detection device. (not shown), and when this limit switch is turned ON by every other screen mounting frame, the solenoid 93 is energized and the locking lever 75e is oscillatedly held at the locking position.

Further, in the above embodiment, a mechanical switch plate switching means is shown which switches the switch plate by the force of moving the carriage back and forth, but
This switch plate switching means is not limited to these, but includes, for example, a solenoid that switches and swings the switch plate, and a detection switch that is activated in conjunction with the back and forth movement of the carriage, on the cam plate or machine base. The configuration may be such that a solenoid is actuated by a command from this detection switch to switch the switch plate.

In addition, the switch converter is provided so as to be swingable, and the switch plate is switched using the swing of the switch converter. The sliding of the rut converter may be used to switch the rut plates.

In addition, a cam follower that fits into the cam groove for distribution is attached to the distribution lever to increase the amount of distribution, but this cam follower can also be attached directly to the spindle; In this case, it should be installed in a way that allows the spindle to rotate.

In addition, in the above embodiment, -J shows a case in which the sealed tube in a horizontal state is held and raised up to be mounted on the screen mounting frame in a substantially vertical state. In this case, the support shaft is provided on the carriage so that it can slide left and right but cannot rotate, and the front end of the carriage can be moved up and down at the forward end position of the carriage, and the screen gripping device itself can be moved vertically. All you have to do is move it up and down.

The vertical movement of the carriage can be easily performed by providing a recess in the guide groove of the guide rail and fitting the vertical roller into the recess.
