Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a nori-attached cage attachment device for attaching a seaweed sealing tube (hereinafter referred to as an attachment) after a dewatering process to a tray attachment frame of a dryer, and a cage gripping device for grasping the attachment. The distribution of the screen gripping device that moves the screen left and right is related to the moving device.

The dryer's screen mounting frame is horizontally long so that multiple screens can be installed side by side, and the trimming protrusions provided between adjacent screen mounting positions on this screen mounting frame extend the width of the dryer. In order to make it as narrow as possible, both pipes have the same mounting position.

Therefore, when attaching attachments to the screen mounting frame, they cannot be attached to adjacent screen attachment positions at the same time, but must be attached one after another so that the ends of the attachments overlap.

In addition, the protrusions of the trimmings on each screen mounting frame of the dryer are designed to prevent interference with the protrusions on the successive screen mounting frames, and to reduce the pinch when installing each screen mounting frame to the rotation chain. Every other mounting frame is slightly shifted laterally (by about 8 mm for transport).

Therefore, when mounting attachments on the screen mounting frames, it is necessary to change the mounting position for each screen mounting frame.

Furthermore, when attaching the attachment to the screen mounting frame, accurate positioning is required because the attachment is covered with seaweed and there is only a small amount of hooking allowance left.

For the above-mentioned reasons, conventionally the dryer was attached to the screen mounting frame one by one by hand, and automation of this work has been desired.

Therefore, in recent years, research has been progressing on devices that automatically attach the attached screen to the screen mounting frame, and the present invention also relates to a series of automated devices.

The present invention reliably stabilizes the screen gripping device toward two adjacent screen mounting positions of the screen mounting frames even when the screen mounting positions of the screen mounting frames in the dryer are slightly shifted every other screen. The purpose of the distribution of the cage gripping device in the nori-covered cage mounting device, which allows the distribution to be moved, is to provide a moving device.

is swung against the spring 78, so that the feed pawl 80 rotates the die wheel 70 by one feed tooth 72, or 90 degrees.

Incidentally, the mold wheel 70 may be rotated by the driving force of a motor, cylinder, or the like (in that case, it is not necessarily necessary to rotate it and it is sufficient to rotate it reciprocatingly).

Reference numeral 83 denotes a push-up device for pushing up the attachment 6 that has been conveyed to the gripping standby position on the conveying roller 1 to the gripping position by the screen gripping device 43, and an elevating rod 84 is supported by a bracket 85 so as to be movable up and down. The roller 86 attached to the crankshaft 28 interferes with the push-up piece 87 fixed to the crankshaft 28 and is pushed up every time the crankshaft 28 rotates.
Since this push-up device 83 is not a feature of the present application, detailed explanation will be omitted.

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

When the chopsticks 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 the conveyance roller 10 rotations, and are placed on the stop plate 7. It is received and stopped at a predetermined gripping standby position.

The attachment 6 is transported to the gripping standby position 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 83 is in the lowered position.

Thereafter, the carriage 19 is moved backward by the rotation of the crankshaft 28, and the horizontal rollers 22 of the carriage 19 abut against the stopper bolts 35, so that the carriage 19 is stopped at the final end position.

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

This reciprocating carriage 19 is stopped by the stopper bolt 35,
The crankshaft 28 is rotated just before the rear dead center of the crank 29, and the subsequent rotation of the crankshaft 28 is performed while compressing the spring 34 of the connecting rod 30 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 attachment 6 in the gripping standby position is gripped by the screen gripping device 43 in the following manner.

That is, as the crankshaft 280 rotates, the push-up piece 87 interferes with the roller 86 of the lifting rod 84 and raises the entire push-up device 83 by a predetermined amount, thereby causing the push-up device 83 to move the attachment 6 in the gripping standby position as shown in FIG. It is pushed up to the gripping position shown by the line, and the attachment 6 is reliably gripped by the suspended screen gripping device 43.

When the attachment 6 is gripped, the crankshaft 28
Due to this rotation, the push-up piece 87 is detached from the collar 86, and the push-up device 83 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.

When the carriage 19 is moved forward in this way, 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, so that the distribution is carried out by the lever 48. 48 is swung to the left as shown in FIGS. 1 to 3.

For this distribution, the roller 52 moves the support shaft 37 to the left by the swinging of the lever 48, and when the carriage 19 is at the forward end position, the screen gripping device 43 is moved to one screen mounting position of the screen mounting frame 54 in the dryer. The support shaft 37 is moved to a position corresponding to .

This movement of the support shaft 37 is carried out extremely smoothly since it 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 left roller 59 of the turn converter 57 in the turn plate cutting wedge means 56 comes into contact with the left guide plate 61 and moves counterclockwise as shown in FIG. As a result, the right roller 59a is positioned to the side of the pivot bolt 58 and this state is maintained.

Furthermore, when the carriage 18 is moved forward, the roller 46 of the engagement lever 45 is guided by the plate cam 47 and swung as shown by the imaginary line in FIG. The support shaft 37 supported on the screen is rotated, and as a result, the screen holding device 43 is swung approximately 90 degrees, and the screen mounting frame 54 is rotated.
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 attachment 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 cage gripping device 43 is swung downward by its own weight, and for distribution, the lever 48 is swung to the right, and the support shaft 37 is returned to its original intermediate position. As a result, at the retracted end position of the carriage 19, the screen gripping device 43 is returned to its original position and is opposed to the attachment 6 next to the gripping standby position where it has been conveyed up to this point.

Further, when the carriage 19 is moved backward, the right roller 59a of the turning converter 57, which has been swung as described above, is located near the rearward end of the carriage 19, and the switching operation plate is in the state shown in FIGS. 1 and 3. 63 and swings the switching operation plate 63 clockwise in FIG. 3.

Therefore, the swinging motion of the switching operation plate 63 is transmitted to the driven arm 68 via the operating arm 66 and the intermediate arm 67, thereby causing the switch plate 14 to switch and swing.

Furthermore, when the carriage 19 is moved backward, the carriage 19
The engagement piece 81 is distributed to the engagement roller 82 of the displacement means 69.
The swing plate 77 swings against the spring 78, and the feed claw 80 moves the mold wheel 70 in 90 degree increments.

However, even if the model car 70 is rotated 90 degrees in this way,
The cam follower 74 attached to the cam plate 12 is positioned within the semicircular groove 73a having the same radius as before, and the cam plate 12 is not swung.

Thereafter, the cage gripping device 43 grips the next sealed tube 6, and the carriage 19 is moved forward again, but this time the sorting lever 4
The 8 cam follower 53 is guided into the other cam groove 13, and the lever 48 is vibrated 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 right roller 59a of the turning converter 57 comes into contact with the guide plate 1□61a and is swung clockwise during the forward movement.

Furthermore, the oscillating plate 77 of the displacement means 69 is distributed by a spring 78.
It is restored by

Thereafter, the carriage 19 is moved backward, but this time the left roller 59 of the turning converter 57 is moved near the rearward end of the carriage 19 (
The switching operation plate 63 comes into contact with the engagement piece 65 of the switching operation plate 63 to swing the switching operation plate 63 as shown in FIG.
4 is switched and swung.

Further, the engagement piece 81 of the carriage 19 comes into contact with the engagement roller 82 and causes the swing plate 77 to swing, thereby causing the mold wheel 70 to move into the 9
Rotated 0 degrees.

When the mold wheel is rotated 90 degrees in this manner, the cam follower 74 is guided into the semicircular groove 73b having a different radius than before.

Therefore, the cam plate 1-2 is slightly swung leftward about the pivot bolt 16, and the position of the screen gripping device 43 is displaced.

Thereafter, the carriage 19 repeats forward and backward movements in the same manner as described above, but before the carriage 19 moves forward next time, the screen mounting frame 54 of the dryer is rotated, and the next screen mounting frame 54 is rotated. is kept standing.

The screen mounting position in this screen mounting frame 54 is the previous screen mounting frame 5.
4, the cam plate 12 is slightly swung and the position of the screen gripping device 43 is displaced, so the screen gripping device 43 is accurately opposed to the screen mounting position of the screen mounting frame 54, and the sealed tube 6 is mounted on the screen mounting frame 54.

Then, when the carriage 19 moves forward twice, the cam follower 74 of the cam plate 12 is guided into the semicircular groove 73a again by the rotation of the model wheel 70, thereby causing the cam plate 12 to swing slightly to the right. and then returned to the original position shown in FIG.

After that, until the carriage 19 moves forward, the screen mounting frame 5
4 is rotated, and the next screen mounting frame 54 is held upright.

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

4 and 5 show a second embodiment of the present application, in which the turning plate cutting wedge means 56e is constructed as follows.

That is, the switch converter 57e is pivotally attached to the lower part of the front end side of the lever 48e via a pivot bolt 58e so as to be able to swing left and right, and a pin 88 implanted in the switch converter 57e is attached to the lower part of the front end side of the lever 48e. It is located within the notch 17e.

The rear end side of this notch 17e is formed in the guide surface 90 so as to become narrower toward the central passage groove 89, and the reciprocating carriage 19
Each time the pin 88 touches the guide surface 90 near the retreating end of e.
The turn converter 57e is returned to the neutral position by being guided by.

Reference numeral 91 denotes a switching piece as a switching mechanism 62e provided rearward so as to swing together with the switch converter 57e, and 92 an engagement piece provided integrally with the pivot portion of the switch plate 14e facing forward. The switching piece 91 connects to the engaging piece 92 near the retreating end of 19e.
It is provided at a position where it can come into contact with.

Reference numerals 61e and 61ae are guide plates attached to the front end of the cam plate 12e, and the lever 49e is distributed as the carriage 19e moves forward, and the roller 59e of the turning converter 57e is distributed during the movement.

59ae is received to swing the turning converter 57e.

As described above, when the lever 49e is moved to the left as the carriage 19e moves forward, the turn converter 57e swings as shown by the imaginary line in FIG. is,
After that, when the carriage 19e is moved backward, the switching piece 91 enters the left side of the engagement piece 92 near the backward end, and the pin 88
is guided by the guide surface 90 and the switch converter 57e is swung to the neutral position, the switching piece 91 comes into contact with the engagement piece 92 and swings it, thereby causing the switch plate 14e to swing. be done.

Further, when the distribution lever 49e is moved to the right, the switch plate 14e is similarly switched and swung in the opposite direction to that described above.

Incidentally, parts that are considered to have the same or equivalent configuration as those of the above embodiment are given the same reference numerals as those of the above embodiment with the letter "e", and redundant explanation is omitted.

(In the third embodiment as well, the alphabet f is similarly added to omit repeated explanation.

) Figures 6 and 7 show a third embodiment of the present application, in which the turn plate cutting wedge means 56f and the distribution displacement means 69f are constructed as follows.

First, referring to the switch plate cutting wedge means 56f, the switch converter 57f is pivotally attached to the lever 48f via a pivot bolt 58f, substantially the same as in the second embodiment.
The roller 93 attached to the notch 17 of the cam plate 12f
It is located within f.

The rear end side of the notch 17f is formed on the guide surface 90f toward the passage groove 89f, and the roller 93 is guided by the guide surface 90f near the retreating end of the carriage 19f, and the turning converter 5
7f is returned to the neutral position.

A switching mechanism 62 provided rearward integrally with the turn converter 57f
The switching piece 91f as f is set at a position where it can come into contact with an engaging piece 92f planted on the switching plate 14f near the retreating end of the carriage 19f.

Further, as the carriage 19f moves forward, the roller 93
The inner surface of the notch 17f of the cam plate 12 also serves as guide plates 1□61f and 61af, which receive and swing the turning converter 57f.

Reference numeral 94 denotes a notch that prevents the turning converter 57f from swinging.

As described above, when the switch converter 57f swings back near the retreat end of the carriage 19f, the switching piece 91
f comes into contact with the engaging piece 92f, and the switching plate 14f is switched and swung.

In this embodiment, since interference between the switching piece 91f and the engaging piece 92f can be prevented, it is possible to easily position the retreating end of the carriage 19f.

Next, regarding the distribution of the displacement means 69f, 95 is a displacement lever pivotally mounted on the base plate 9f of the machine base 2f,
It is biased by a spring 96 and comes into contact with a stopper -97.

98 is a roller attached to the displacement lever 95, and the cam plate 1
It is fitted into a groove 99a in the front-rear direction of a groove member 99 fixed to 2f.

An engagement roller 82f is attached to the tip of the displacement lever 95 via an engagement shaft 100, and when the carriage 19f moves backward, it engages with the engagement piece 81f and is moved backward, whereby the displacement lever 95 is moved backward by the spring 96. It is designed to be swayed against the

Reference numeral 101 designates a locking lever pivotally supported on the base plate 9f, which is biased clockwise by a spring 102 and whose position is regulated by coming into contact with a groove member 99 serving as a stopper. This is a solenoid that swings the locking lever 101 to a predetermined position against a spring 102, and is connected to the locking lever 101 by a rod 104.

The solenoid 103 is a two-way carriage 19f that moves back and forth.
A suitable means such as a limit switch is connected so that the carriage 19f is energized while it moves back and forth twice every other time, that is, every other tube mounting frame of the dryer is energized.

As described above, when the carriage 19f is moved backward, the engagement piece 81 engages with the engagement roller 82f and swings the displacement lever 95 backward, thereby causing the cam plate 12f to move slightly to the right. However, if the solenoid 103 is not energized, then as the carriage 19f moves forward, the displacement lever 95 is also swung forward by the spring 96 and positioned by the stopper 97, whereby the cam Board 1
2f is slightly swung leftward and stopped at the original position, and the cam plate 12f at this position moves the screen gripping device for sorting.

However, the carriage 19f moved back and forth twice and the carriage 19f moved back and forth twice.
When the solenoid 103 is energized when f is moved to the backward end, the locking lever 101 engages and locks the engagement shaft 100, and even if the carriage 19f moves forward thereafter, the displacement lever remains unchanged. 95 is held in a swung state, and the cam plate 12
f is also held at a position slightly swung to the right, and the cam plate 12f in this position moves the screen gripping device for distribution.

Incidentally, in each of the above embodiments, a mechanical switch plate cutting wedge means for switching the switch plate by the back and forth movement force of the carriage was shown, but
This turn plate cutting wedge means is not limited to these (
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 are installed on the cam plate or machine base, and the solenoid is activated by the command of this detection switch to move the switch plate. It may be configured to switch.

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.

Furthermore, in each of the above embodiments, a case is shown in which the horizontal fixture is grasped and raised upright, and the fixture is attached to the screen mounting frame in a substantially vertical position, but the fixture may also be mounted in a horizontal position. Possible, and in this case, the support shaft should be installed on the carriage so that it can slide left and right, but not 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 up and down. All you have to do is let it happen.

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.

Further, in the above embodiment, the reciprocating table is moved back and forth by rotation of the crankshaft, but it may be moved by other suitable means.

Furthermore, the distribution in each of the above embodiments is not limited to the displacement means; for example, the rear end side of the cam plate may be swingably pivoted to the machine base, and the axial position may be slightly varied around the periphery. A cam body having a cam groove consisting of two half-circumferential grooves is rotatably installed on the machine base so that the rotation center line is in the left-right direction, and a cam follower attached to the front end side of the cam plate is installed in this cam groove. and the two cam bodies are configured to be rotated by 90 degrees for each reciprocating movement of the reciprocating table in relation to the back and forth movement of the reciprocating table, and the cam plate is rotated by 90 degrees for each reciprocating movement of the reciprocating table. The distribution may be performed by displacing the movement position by swinging in the left-right direction.

Furthermore, in the above embodiment, the cam plate is pivotally supported on the machine base, and the distribution is made by swinging the cam plate by the displacement means, but the cam plate is held on the machine base so as to be slidable from side to side. The distribution may be performed by sliding a cam plate using a displacement means.

In addition, in the distribution, the operation of the displacement means is related to the back and forth movement of the carriage, but this operation is related to the rotation of the screen mounting frame in the dryer, and the direction of displacement of the cam plate is connected to the screen mounting frame of the screen mounting frame. It is preferable to make the adjustment correspond to the direction of positional deviation because it facilitates adjustment at the time of starting.

As described above, in this invention, each time the carriage moves back and forth once, the screen gripping device is moved left and right alternately by the pitch of the screen mounting position of the screen mounting frame, and the carriage moves twice. Each time it moves back and forth, the screen gripping device is distributed so that the moving position is alternately displaced left and right by the amount of deviation of the screen mounting position of the screen mounting frame, so that the screen mounting position of the screen mounting frame is one of the screen mounting frames. Even if the screen is misaligned, the screen gripping device can be sequentially moved to two adjacent screen mounting positions on the screen mounting frame. It can be attached to the machine, resulting in significant labor savings.

In addition, in the present invention, a carriage is mounted on a pair of left and right guide rails fixed to the machine base so as to be movable back and forth, and the carriage is mounted on a support shaft supported by the carriage so as to be movable linearly in the left and right direction. Since the gripping device is installed, the movement and displacement of the screen gripping device can be performed extremely accurately and stably.Additionally, the attachment can be attached to the exact position of the screen installation position. Mistakes can be prevented.

In addition, since the support shaft can be stably supported on the reciprocating table, it is possible to easily attach a large number of screen gripping devices to this support shaft. The attachment can be reliably attached to the screen attachment position, and has the effect of being applicable not only to small-sized dryers but also to large-sized dryers.
