Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for automatically attaching a nori device (hereinafter referred to as position) to a dryer screen mounting frame after a dewatering process is completed. It is.

When attaching the attachment to the dryer, since the sho nori is attached to the attachment, it must be stably attached without damaging the sho nori.

In addition, since the sho-nori is attached to the attachment, there are few hook-type attachments that can be used to grasp and attach the attachment.

In addition, in general dryers, there are many attachments (
For example, 4, 6, 8, and 10 sheets) are horizontally long, and the protrusions of the trimming branches are commonly used at the adjoining positions for installing both screens. It is difficult to provide a cage gripping device for each case due to the size.

Furthermore, in the case of a type of dryer in which every other screen mounting frame is slightly shifted (by 8 meters) to prevent the protrusions of the trimming from interfering with each other, it is necessary to shift the mounting position of the attachments by this amount of shift. was there.

For the above-mentioned reasons, attaching the attachment to the dryer has traditionally been carried out manually one by one, which is an inefficient task that requires a lot of labor.

Therefore, the present invention aims to provide a structurally stable mounting device that allows the mounting device to be installed vertically in a dryer, and which is structurally stable so as to prevent the seaweed from being damaged. The hangings transported in a substantially horizontal state are gripped by a suspended downward-facing screen gripping device, and when the support device of this screen gripping device is moved toward the dryer, the screen gripping device is moved by a plate cam along with this movement. The present invention is characterized in that it can be smoothly rotated sideways by using the support device, and the horizontal screen gripping device can be attached to the screen mounting frame of the dryer using the movement of the support device.

In addition to the above, the present invention also allows the screen gripping device to be moved alternately to the left and right, so that it can be put to practical use without any problem even in a dryer in which the protrusions of the trimming branches are shared at adjacent pipe attachment positions. It is characterized by

Then, the locking lever 75 is moved to the groove member 7 by the spring 76.
1, the detection arm 84 is in the position shown by the imaginary line in FIG. The locking lever 75 is pivoted to the locking position shown in FIG.

Reference numeral 87 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 cage gripping device 43. The roller 90 attached to the crankshaft 28 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 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 0 rotation 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 come into contact with the stopper bolts 35, so that the carriage 19 is stopped at the rearmost 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 28 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 be placed in the standby position 6 in FIG. is pushed up to the gripping position shown by the imaginary line, and the attachment 6 is reliably gripped by the suspended screen gripping device 43.

Then, after gripping the stiffness attachment 6, the crankshaft 28
Due to this rotation, the push-up piece 91 is removed from the roller 90, and the push-up device 87 is returned to the standby position by falling under its own weight.

After that, the swing arm 23 is moved to the second position by 280 rotations of the crankshaft.
In the figure, the carriage 1 is swung counterclockwise.
9 is moved forward, and the screen gripping device 43 attaches the gripped attachment 6 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 off to the side.

Then, the screen mounting frame 54 one position in front engages with the detection arm 84 of the detection device 79 and rotates it, so that the driven arm 85 pulls the wire 77b and moves the locking lever 75 to the locking position. It's shaking.

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. .

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 distribution lever 48 is swung to the left as shown in FIGS. 1 to 3.

By swinging this distribution l/bar 48, the distribution is made by the lever 48.
moves the support shaft 37 to the left via the drum 42 and the roller 52, 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 at the mounting position in the dryer. The support shaft 37 is swung to the corresponding position.

This movement of the support shaft 31 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 switch converter 57 in the switch plate switching means 56 comes into contact with the left contact surface 64 and moves slightly clockwise as shown 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 and the screen mounting frame 54 is rotated by approximately 90 degrees.
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.

After that, by 280 rotations of the crankshaft, 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 clockwise 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 75, 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 switching plate switching means 54 enters the right side of the engagement pin 63, swings the engagement pin 63, and switches the switching plate 14. .

Therefore, the switch plate 14 is returned to the initial position, and the next time the carriage 19 moves forward, the cam follower 54 is directed to the left.

After that, the carriage 19 repeats the forward and backward movement as described above, but the rotation chain 92 of the screen mounting frame 54 in the dryer is rotated by -pitch until the carriage 19 is next moved forward. .

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.

Further, the screen mounting frame 54 one position before the screen mounting frame 54 at the mounting position 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 by the rotation of the rotation chains 9 and 20, and the tension on the wire 77b is released. The lever 75 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 since this screen mounting frame 54 does not rotate the detection arm 84, the rotation chain 92 is rotated by a certain pitch. Retained.

Then, 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, which causes the cam plate 12 to move to the left. Slightly oscillating displacement.

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. This is then rotated and
is pulled to position the locking lever 75 at the locking position, and the displacement lever 67 is locked and held 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 78 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 attachment 6 is automatically attached to the screen attachment frame 54 of the dryer.

FIG. 5 shows a second embodiment of the displacement means, in which a solenoid 93 for swinging the locking lever 75e against the spring 76e 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.

It should be noted that portions that are considered to have the same or significantly equivalent configurations as those of the above embodiment are given the same reference numerals as those of the above embodiment, with an alphabento e added thereto, and redundant explanation will be omitted.

Note that the present application is not limited to the above embodiments, and may be modified without departing from the technical idea.

For example, instead of using a carriage as a support device, a swinging arm may be used, and the bearing of the support shaft may be rotatably attached to this swinging arm.

Further, the bearing does not necessarily have to be a roller bearing, and a square hole may be used to slidably support the support shaft.

Further, the cam follower may be attached directly to the spindle, in which case it is attached to allow rotation of the spindle.

Further, although the above embodiment shows a mechanical switch plate switching means, electrical means may also be used. A detection switch may be provided, and a solenoid may be operated in response to a command from the detection switch to switch the switch plate.

Furthermore, the distribution may be modified so that the displacement means is operated in conjunction with the reciprocating movement of the support device, for example, the end face has an annular cam groove consisting of two semicircular grooves with different center radii. A cam body is rotatably mounted on the machine base with the center line of rotation oriented in the vertical direction, and a cam follower attached to the front end of the cam plate is fitted into the annular cam groove to support the cam body. The cam plate may be configured to be rotated by 90 degrees each time the device moves back and forth, and the cam plate may be oscillatedly displaced every two times the support device moves back and forth.

As described above, in the present invention, when the support device is moved forward, the downward-facing screen gripping device is rotated sideways by approximately 90 degrees and moved, so that the screen holding device stands upright. The attachment can be attached to the screen mounting frame, resulting in significant labor savings.

In addition, the screen gripping device is stopped downward at the retreating end of the support device.The screen gripping device in this stopped state is pushed up from below to grip the screen, which prevents the screen gripping device from swinging when gripping. It is possible to hold the sho nori in an accurate position stably, and because it grips the sho nori in a substantially horizontal state, it has the advantage that the sho nori can be easily transported using a roller conveyor or the like without damaging the sho nori. be.

Furthermore, even if the attachment is attached by rotating the screen gripping device approximately 90 degrees from downward to sideways as described above, the rotation of the screen gripping device is controlled by the plate cam as the support device moves forward. This has the advantage that the movement of the screen gripping device can be stabilized, and the attachment can be stably mounted at an accurate position on the screen mounting frame.

Furthermore, since the supporting device that reciprocates supports the support shaft of the screen gripping device, and the reciprocating motion of the support device is used to swing the screen gripping device, there is an advantage that the structure can be simplified.

In addition, in the present invention, the screen gripping device is moved alternately in the left and right directions in relation to the reciprocating movement of the support device, so that two adjacent screen mounting positions on the screen mounting frame can be moved. The attachments can be attached one after another with a single screen gripping device, increasing work efficiency, and this can also be easily implemented in dryers where the twig trimming protrusions on the screen mounting frame are shared at both screen mounting positions. It has the effect of

In addition, in the present invention, the movement position of the screen gripping device is alternately displaced in the left and right direction in relation to the reciprocating movement of the support device or the rotation of the screen mounting frame in the dryer. Is the screen mounting position one of the screen mounting frames? Even if the dryer is misaligned, the attachment can be attached to the correct position on the screen attachment frame, and this has the effect of preventing attachment errors and damage to the seaweed.
