Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for hanging a screen in a dryer, which automatically attaches a screen with seaweed (hereinafter referred to as a screen) to a screen mounting frame of the dryer after a dewatering process is completed. It is something.

When attaching the tank to the dryer, since the dried seaweed is attached to the dryer, it must be stably attached without damaging the dried seaweed. In addition, because the seaweed is attached to the tank,
There is only a small amount of hooking allowance for the fish tank that can be used to hold and attach the fish tank, and the fish tank must be held and mounted stably at an accurate position. In addition, in a general dryer, there are many attached cages (for example, 4,
It is horizontally long so that it can be installed with 6, 8, and 10 sheets, and the protrusions on the vertical bars are shared by two adjacent screen mounting positions. It is difficult to install a cage gripping device in the tank due to the size. Furthermore, in the case of a type of dryer in which every other cage mounting frame is slightly shifted (about 8 mm) to prevent the protrusions on the vertical bars from interfering with each other, the device position of the attached cage should be shifted by this amount of deviation. The need arose. For the above-mentioned reasons, conventional equipment for loading sheets into dryers has been done carefully by hand, one sheet at a time, which is an inefficient operation that requires a lot of manpower.

Therefore, the present invention aims to provide a method for hanging a screen on a dryer that allows the screen to be installed smoothly and stably in a dryer in which the screen is mounted vertically. The sent cage is positioned by contacting the stopper, the positioned cage is pushed up and delivered upwards to the waiting cage gripping device, and the gripped cage is rotated approximately 90 degrees to a nearly vertical position. The present invention is characterized in that the screen is held and then pressed against the screen mounting frame of the dryer in a substantially vertical position, thereby attaching the screen to the protrusion of the screen mounting frame. In addition to the above, the present invention also has the feature that the screen gripping device is 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 vertical bars are shared at adjacent screen mounting positions. It is a feature.

That is, the rotary wheels 38 are rotatably supported on the left and right sides of the carriage 19, the support shaft 37 is rotatably inserted into the hole 38a of the rotary wheel 38, and is attached to the side end surface of the rotary wheel 38. The four outer circumferential surfaces of the support shaft 37 are held by roller bearings 41 consisting of four pairs of two bearings 40 rotatably attached via metal fittings 39, and the left and right movement of the support shaft 37 is smoothly performed via the bearings 40. I'm trying to make it happen. A drum 42 having an engagement groove 42a on its outer periphery is fixed to the support shaft 37, and a support arm 44 for supporting a screen gripping device 43 is fixed to this drum 42.
A plurality of the screen gripping devices 43 are provided corresponding to every other screen mounting position of the screen mounting frame 54 in the dryer. However, since this screen gripping device 43 is not a feature of the present application, a detailed explanation thereof will be omitted. Reference numeral 45 denotes a lever having one end fixed to the outer periphery of the rotating wheel 38 and an engaging roller 46 rotatably attached to the other end, and is biased counterclockwise in FIG. 2 by the weight of the screen gripping device 43. The engagement roller 46 comes into contact with a plate cam 47 attached to the machine base 2, and the reciprocating base 19
When the plate cam 4 moves forward as shown in FIG.
7, and the screen gripping device 43 is rotated approximately 90 degrees (or approximately 110 degrees) from downward to sideways. Reference numeral 48 denotes a distribution lever whose one end side is pivoted via a pivot bolt 50 so as to be able to swing left and right to a holding plate 49 fixed to the rear part of the carriage 19, and a U-shaped fitting part 51 is formed at the other end side. ,
The fitting portion 51 is fitted into the drum 42 of the support shaft 37, and a pair of rollers 52 rotatably attached to the upper and lower inner sides of the fitting portion 51 are fitted into the engaging groove 42a of the drum 42. ing. A cam follower 53 that fits into the cam groove 13 of the cam plate 12 is rotatably attached to the distribution lever 48, and as the carriage 19 moves back and forth, the cam follower 53 is distributed and moved over the cam groove 13. As a result, the distribution lever 48 is swung to the left and right to increase the number of the support shafts 37 and to cause the distribution to move. In this case, the distributed movement amount of the support shaft 37 is determined so that the screen gripping device 43 faces the adjacent screen mounting positions of the screen mounting frame 54 in the dryer, respectively, as shown in FIG. The pitch of the vertical bar 55 is determined to be substantially the same as the pitch L of the protrusion 55a provided on the vertical bar 55.

Reference numeral 56 denotes a switch plate switching means for switching the switch plate 14 in relation to the movement of the carriage 19 near the backward end of the backward movement of the carriage 19, and in this embodiment is constructed as follows. That is, reference numeral 57 denotes a turning converter which is pivotally attached to the lower part of the front end side of the distribution lever 48 via a pivot bolt 58 so as to be able to swing from side to side.A roller 59 is rotatably attached to the front end.
9 is located within the notch 17 of the cam plate 12. The rear end side of this notch 17 is formed in the guide surface 61 so as to become narrower toward the relief groove 60 in the center, and the roller 59 is guided by the guide surface 61 each time near the retreating end of the carriage 19. The turn converter 57 is adapted to be returned to the neutral position. Reference numeral 62 denotes a switching piece provided integrally with the turning converter 57 facing backward; 63 an engagement pin implanted in the front part of the pivot portion of the turning plate 14; It is provided at a position where it can come into contact with the engagement pin 63. Reference numerals 64 and 64a are abutting surfaces formed at the front end of the notch 17, which receive the rollers 59 of the turning converter 57 during the sorting movement of the sorting lever 48 as the carriage 19 moves forward, as shown in FIG. As shown by the phantom line, the turn transformer 57
It is designed to oscillate to some extent. 65 is a notch that prevents the turning converter 57 from swinging. As described above, when the carriage 19 is moved forward, the switching converter 57 is swung, and when the carriage 19 is then moved backward, the switching piece 62 is connected to the engagement pin 63 near the retreating end. When the roller 59 is guided by the guide surface 61 and the turning converter 57 is swung to the neutral position, the switching piece 62 comes into contact with the engagement pin 63, causing it to swing. Switch the plate 14 to the opposite side. In this embodiment, even if the backward end position of the carriage 19 changes, the switching piece 6
2 and the engagement pin 63 so as not to interfere with each other, the retreating end of the carriage 19 can be easily positioned.

Next, 66 is a distribution displacement means for alternately swinging the distribution movement position of the material gripping device 43 in the left and right direction every pitch rotation of the screen mounting frame 54 in the dryer;
This embodiment is configured as follows to swing the cam plate 12. Reference numeral 67 denotes a displacement lever pivotably mounted on the base plate 9 of the machine base 2, and is biased forward by a spring 68 to move the stopper 69 on the base plate 9.
It is now coming into contact with A cam follower 70 is attached to the middle part of the displacement lever 67, and is fitted into a groove 71a in the longitudinal direction of a groove member 71 fixed to the cam 12.
When the cam plate 12 is swung rearward against the force 8, the cam plate 12 is swung to the right. 72 is an engagement roller attached to the tip of the displacement lever 67 via an engagement shaft 73, and when the carriage 19 moves backward, the engagement roller 72
9 and is moved rearward, thereby swinging the displacement lever 67 rearward. Reference numeral 75 denotes an L-shaped locking lever pivotally supported on the base plate 9, which is biased clockwise in FIG. It's getting old. The locking portion 75a of the locking lever 75 is connected to the engagement shaft 75a when the displacement lever 67 is swung rearward.
Their positional relationship is determined so that they can be locked. Further, the tip of the locking portion 75a is such that when the displacement lever 67 is swung rearward while the locking lever 75 is swung to the locking position, the locking shaft 73 moves the locking lever 75 to the spring 78. It is formed on a slope so that it resists and pushes back. 77 is a flexible wire, wire tube 77a and wire 77b
One end of a wire tube 77a is fixed on the board 9, and one end of the wire 77b is connected to the locking lever 75 via a spring 78 whose elasticity is greater than the elasticity of the spring 76. When pulled rearward, the locking lever 75 swings counterclockwise.

79 is a screen mounting frame 54 at the device position in the dryer.
This is a detection device that detects the type of screen mounting frame 54, that is, whether the screen mounting position is shifted to the left or right. It is configured as follows to detect the Reference numeral 80 denotes a holding plate attached to a frame 81 of the dryer, and 82 a support portion provided on this holding plate 80. This support portion 82 rotatably supports a detection shaft 83. A detection arm 84 is fixed to one end of this detection shaft 83, and a driven arm 85 is fixed to the other end. Reference numeral 86 denotes a mounting piece provided on the holding plate 80 to which the other end of the wire tube 77a of the flexible wire 77 is attached.
The other end of b is connected to the tip of the driven arm 85. When the locking lever 75 is in contact with the groove member 71 due to the spring 76, the detection arm 84
is located at the position shown by the imaginary line in Fig. 4, and the screen mounting frame 5
4 contacts the detection arm 84 and rotates it, the driven arm 85 pulls the wire 77b and swings the locking lever 75 to the locking position shown in FIG.

Reference numeral 87 denotes a push-up device for pushing up the cage 6 that has been conveyed to the grasping standby position on the conveying roller 1 to the grasping position by the cage gripping device 43, and an elevating rod 88 is supported by a bracket 89 so as to be movable up and down. 88
A roller 90 attached to the crankshaft 28 interferes with a push-up piece 91 fixed to the crankshaft 28 so that the crankshaft 28 is pushed up every revolution, but the structure of this push-up device 87 is a feature of the present application. By the way, since it is not relevant, I will omit the detailed explanation.

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

When the attached cages 6 that have completed the dewatering process are placed one by one on the transport roller 1 by an automatic cage feeder (not shown), they are transported horizontally and shifted to one side by the rotation of the transport roller 1, and the stop plate 7 and is stopped at a predetermined gripping standby position.

The transfer of the retainer 6 to the gripping standby position is carried out at a good timing while the carriage 19 is moved forward by the rotation of the crankshaft 28 and the push-up device 83 is located at 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 faces the additional screen 6 in the gripping standby position. This reciprocating carriage 19 is stopped by the stopper bolt 35 at a certain point before the rear dead center of the crank 29, and the subsequent rotation of the crankshaft 28 is performed by the spring of the connecting rod 30 until the rear dead center of the crank 29. This is done while compressing 34. Therefore, the carriage 19 is stopped at the rearmost position for a while, and during this time, the cage 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 8
7 interferes with the roller 86 of the lifting rod 84 to raise the entire pushing up device 83 by a predetermined amount, whereby the pushing up device 83 pushes up the retainer 6 in the gripping standby position to the gripping position shown by the imaginary line in FIG. The attached fish tank 6 is surely held by a fish tank gripping device 43 which is in a stopped state. When gripping of the retainer 6 is completed, the push-up piece 91 is removed from the roller 90 due to the rotation of the crankshaft 28, and the push-up device 87 is returned to the standby position by falling under its own weight.
Thereafter, due to the rotation of the crankshaft 28, the swinging arm 23
is swung counterclockwise in FIG.
The attached tray 6 is attached to the tray mounting frame 54 of the dryer in the following manner. 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 before this engages with the detection arm 84 of the detection device 79 and rotates it, whereby 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.
has been oscillated to the right. When the carriage 19 is moved forward in this state, the sorting lever 4
The cam follower 53 of No. 8 comes into contact with the switching plate 14 on the way and is guided into one of the cam grooves 13, so that the distribution lever 48 is distributed and swung to the left as shown in FIGS. 1 to 3. be done. Due to the swinging of this distribution lever 48, the distribution lever 4
8 is a support shaft 3 via a drum 42 and a roller 52.
7 to the left, and at the forward end position of the carriage 19, the screen gripping device 43 swings the support shaft 37 to a position corresponding to one screen mounting position of the screen mounting frame 54 at the mounting position in the dryer. . 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 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 engagement roller 46 of the lever 45 is guided by the plate cam 47 and swung as shown by the imaginary line in FIG. 2, so that the rotary wheel 38 and the support shaft 37 supported by the rotary wheel 38 are rotated. As a result, the cage gripping device 4
3 is swung approximately 90 degrees to face one of the screen mounting positions of the screen mounting frame 54, and is moved forward in this state. Then, at the forward end position of the carriage 19, the screen gripping device 43 moves the held screen 6 to the screen mounting frame 5.
4 into the protrusion 55a and attach it to the screen mounting position.

The subsequent rotation of the crankshaft 28 causes the carriage 19 to move backward, and as the carriage 19 moves backward, the cage gripping device 43 is swung downward while being regulated by the plate cam 47 due to its own weight. The lever 48 is swung to the right, and the support shaft 37 is returned to its original intermediate position, and as a result, the cage gripping device 43 is returned to its original position at the backward end position of the carriage 19. It is opposed to the attachment 6 next to the holding standby position. In addition, the carriage 19
When the switch 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, the roller 59 is guided by the guide surface 61, and the turning converter 57 becomes neutral. When returned to the position, the switching piece 62 contacts the engagement pin 63 and swings it, thereby switching the switching plate 14.

Thereafter, the next cage 6 is gripped by the cage gripping device 43, and the carriage 19 is moved forward again, but this time, the cam follower 53 of the distribution lever 48 is guided into the other cam groove 13, and the distribution lever 48 is moved forward. Swings to the right. Therefore, the screen gripping device 43 is the third
As shown by the imaginary line in the figure, it is moved to the other screen mounting position of the screen mounting frame 54, and the attached screen 6 that is being held is attached to the other screen mounting position of the screen mounting frame 54. 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. still,
In this case, the displacement lever 67 of the distribution displacement means 66 is held in a locked state by the locking lever 75, and the cam plate 12 is displaced to the right.

After that, 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 turn plate 14
is returned to the initial position, and in the next forward movement of the carriage 19, the cam follower 54 is distributed 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 one pitch before the carriage 19 is moved forward next time. . 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 due to the rotation of the rotation chain 92, and the tension on the wire 77b 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 since this screen mounting frame 54 does not rotate the detection arm 84, the rotation chain 92 is rotated one pitch further. Retained.
Then, when the carriage 19 is moved forward, the displacement lever 67 of the distribution displacement means 66 is swung forward by the spring 68 and comes into contact with the stopper 69, thereby causing the cam plate 12 to move slightly to the left. It is oscillated and displaced. Therefore, the distribution movement position of the screen gripping device 43 described above is displaced to the left by the displacement 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 mounting position of the screen mounting frame 54. It is accurately moved to a position corresponding to the position, and the attached retainer 6 that is being held is reliably attached to the retainer attachment position. Thereafter, when the carriage 19 is moved backward, the engagement piece 74
engages with the engagement roller 72 and swings the displacement lever 67 backward, but since the locking lever 75 is located at the open position, it does not lock the displacement lever 67, and the carriage 19 then moves forward again. When moved, the displacement lever 67 is also swung forward. Therefore, by the subsequent back and forth movement of the carriage 19, the screen gripping device 43
The additional screen 6 is accurately attached to the other screen mounting position of the screen mounting frame 54.

After that, until the carriage 19 is moved forward again, the rotation chain 92 of the screen mounting frame 54 in the dryer is rotated by one pitch, and as a result, the screen mounting frame 54 of the dryer is rotated one pitch.
4 engages with and rotates the detection arm 84 of the detection device 79, pulls the wire 77b to position the locking lever 75 in the locking position, and locks the displacement lever 67 in the rearwardly swung position. Stop and hold. Incidentally, the swinging of this locking lever 75 to the locking position is caused by the movement of the displacement lever 6.
If it is done before the backward swing of 7,
The engagement shaft 73 of the displacement lever 67 contacts the slope of the tip of the locking lever 75, and the locking lever 75 is moved by the spring 78.
The engaging shaft 73 is thereby locked in the locking portion 75a. By sequentially repeating the above-described operations, the additional screen 6 is automatically attached to the screen mounting frame 54 of the dryer.

FIG. 5 shows a second embodiment of the distribution 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 (not shown) is provided as a detection device. ), and when this limit switch is turned on by every other screen mounting frame, solenoid 9
3 is excited to swing and hold the locking lever 75e at the locking position. It should be noted that 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 an alphanumeric letter "e" and repeated 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 support shaft, and in that case, it is installed to allow rotation of the support shaft. Also,
Although the above embodiment shows a mechanical switch plate switching means, electrical means may also be used. For example, the switch plate may be operated in conjunction with the reciprocating movement of a solenoid that switches and swings the switch plate and a support device. A detection switch is provided.
A solenoid may be actuated by a command from this detection switch to switch the switch plate. Furthermore, the distributing displacement means may be modified to operate in conjunction with the reciprocating movement of the support device, for example, a cam body having an annular cam groove formed of two semi-circular grooves with different center radii on the end face. is rotatably mounted on the machine base so that the center line of rotation is in the vertical direction, and the cam follower attached to the front end side of the cam plate is fitted into this annular cam groove, and the cam body is attached to the support device. The cam plate may be configured to be rotated by 90 degrees for each reciprocating movement, and the cam plate may be oscillatedly displaced every two reciprocating movements of the support device.

As described above, in the present invention, the screen sent by the conveyance roller is positioned by contacting the stopper, and the positioned screen is pushed up and delivered upward to the waiting screen gripping device, where it is gripped. Turn the screen approximately 90 degrees and deviate it to the left or right, hold the screen in a substantially vertical position, and then press the screen held against the support frame of the dryer, which is in a substantially vertical position, and press the screen against the protrusion of the support frame. As a result, after papermaking and dehydration, the attached cage can be sent in a substantially horizontal state using a conveyor roller, and the attached cage can be attached to a substantially vertical support frame, resulting in significant labor savings. can be achieved. In addition, since the screen gripping device in a stopped state is configured to push up and grip the cage from below, it is possible to reduce the shaking of the screen gripping device when grasping, and to stably hold the cage at an accurate position. Moreover, since the holding tank is held in a substantially horizontal state, the dry seaweed is not damaged when the holding tank is placed on a roller conveyor, etc. Since the cage gripping devices are moved alternately in the left and right directions, it is possible to sequentially attach the attached cages to two adjacent cage mounting positions on the cage mounting frame using a single cage gripping device, improving work efficiency. Moreover, this has the effect that it can be easily implemented in a dryer where the projections on the vertical bars of the screen mounting frame are shared at both screen mounting positions.
