Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a nori-covered cage attachment device for attaching a nori basket (hereinafter referred to as an attachment) that has completed a dewatering process to a cage attachment frame of a dryer, in which a cage gripper that grips the attachment cage is used. This invention relates to a sorting and moving device for a screen gripping device that moves the device left and right.

Conventionally, the work of attaching the attachments to the dryer's screen mounting frame after centrifugal dehydration was done by hand, one by one, and the work of attaching the attachments required an extremely large amount of manpower. .

Therefore, in recent years, research has been progressing to automate the attachment of this attachment to the screen mounting frame, and the present invention also relates to a series of automation devices.

What is important when promoting this automation is that the rigid bar in the middle of the screen mounting frame of the dryer is shared by adjacent screen mounting positions in order to minimize the frame width. It is not possible to attach the attachments to adjacent cage mounting positions at the same time, and it must be done sequentially. Also, if the mounting positions on the attachment frames are misaligned, the sho nori attached to the attachment frames will be damaged. This means that the installation must always be stably moved to an accurate position relative to the screen mounting frame.

Therefore, the present invention stably moves the screen gripping device that grips the attachment and attaches it to the screen mounting frame of the dryer from the attachment position to the two adjacent screen mounting positions of the screen mounting frame. In the nori attachment and attachment device, which allows attachments to be attached alternately to two adjacent attachment positions, the distribution of the bamboo gripping devices is intended to provide a moving device, and a pair of left and right guides are attached to the machine base. The rails are fixed in a substantially horizontal direction, and a carriage is placed on these guide rails so as to be able to move back and forth, and this carriage supports a spindle to which a cage gripping device is attached so that it can move linearly in the left and right direction. The support shaft engages the front end of a lever pivoted to the rear of the carriage, and the machine base is provided with a cam plate having a longitudinal cam groove for the distribution. On this cam plate, a switching plate is pivotally supported at the branch point of the cam groove so that one groove can be selectively closed, and the above distribution is achieved by fitting a cam follower attached to a lever into the cam groove. The present invention is characterized in that it further includes a switch plate switching means near the rear end of the carriage for switching the switch plate in conjunction with the back and forth movement of the carriage.

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 feeding device (not shown), they are conveyed horizontally by the conveyance roller 10 times and shifted to one side, and are placed on the stop plate γ. 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 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 device 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, whereby the push-up device 83 moves the device 6 in the gripping standby position as shown in FIG. The device 6 is pushed up to the gripping position shown by the line, and the device 6 is securely gripped by the suspended screen gripping device 43.

After gripping the device 6, the crankshaft 28
Due to this rotation, the push-up piece 87 is removed from the roller 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 the one pipe 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 switching means 56 comes into contact with the left guide plate 61 and swings 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 19 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.

Then, at the forward end position of the carriage 19, the screen gripping device 4
3 inserts the gripped device 6 into the protrusion 55a of the screen mounting frame 54 and attaches it to the pipe 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 next device 6 in the gripping standby position that 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 movement of the switching plate 63 is transmitted to the driven arm 68 via the working arm 66 and the intermediate arm 67, thereby causing the switching plate 14 to swing.

Furthermore, when the carriage 19 is moved backward, the carriage 19
The engagement piece 81 of the engagement roller 82 of the distribution 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.

After that, the next device 6 is gripped by the screen 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 pipe mounting position of the screen mounting frame 54 as shown by the imaginary line in FIG. let

Further, when the carriage 19 is moved forward, the right roller 59a of the turn converter 5γ comes into contact with the guide plate 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 comes into contact with the engagement piece 65 of the switching operation plate 63 near the retreating end of the carriage 19, and this switching operation plate 63 is swung as shown in Fig. 1, and as a result, the switch plate 1
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 17 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 12 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 calculation mounting frame 54 is the previous screen mounting frame 5.
4 is shifted to the left by a certain amount M, but as mentioned above, 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 shifted to the left. The device 43 is accurately opposed to the screen mounting position of the screen mounting frame 54, and the device 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 mold wheel 10, 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 device 6 is automatically attached to the screen mounting frame 54 of the dryer.

Furthermore, in each of the above embodiments, a case is shown in which the device is held in a horizontal position, raised upright, and mounted on the screen mounting frame in a substantially vertical state; however, the device may also be mounted in a horizontal state. 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 cam plate is pivotably supported on the machine base, and the cam plate is rocked by a displacement means for distribution, and the movement position is displaced for distribution. The displacing means may be omitted for distributing by providing the displacing unit integrally, and displacing the movement position may not be performed for distributing.

As described above, in the present invention, the support shaft of the screen gripping device is supported on the carriage that moves back and forth so as to be movable linearly in the left and right direction, and the distribution by engaging the front end with this support shaft is performed using the lever. The rear end is pivotally attached to the rear of the carriage, and the cam follower attached to the lever is fitted into the cam groove of the cam plate, and as the carriage moves back and forth, the screen gripping device is moved left and right. As a result, bamboo tubes can be mechanically attached one after another to two adjacent screen mounting positions on the screen mounting frame of the dryer using one screen gripping device, resulting in significant labor savings. can.

In addition, the above-mentioned carriage is placed on a pair of left and right guide rails fixed to the machine base so as to be able to move back and forth back and forth to stabilize the movement of the carriage, and the support shaft on this carriage can be moved linearly in the left and right direction. Since the left and right movement of this support shaft is also stabilized by supporting it, the movement of the bamboo gripping device can be performed accurately and stably.This allows the bamboo pipe to be placed in the predetermined position of the cage mounting frame extremely accurately. It is possible to prevent damage to the sheet seaweed by preventing incorrect installation.

In addition, since the support of the support shaft is stable, multiple screen gripping devices can be easily attached to this support shaft, and even when there are many pipe attachment positions on the screen installation frame, this screen installation frame can be easily installed. There is an advantage that bamboo pipes can be attached to all the screen attachment positions by two reciprocating movements of the carriage.

In addition, since the left and right movement of the above-mentioned support shaft is performed by a lever, the distribution of swinging by the cam follower is performed by a lever, so the support shaft can be moved left and right by a small amount of movement of the cam follower, and this allows the cam plate to move horizontally. By reducing the size, the weight of the device can be reduced.
