Description

The present invention relates to a centrifugal dehydrator, and more particularly to a centrifugal dehydrator that dehydrates by rotating a group of cases in which a plurality of cases are stacked.

Conventionally, there is known a centrifugal dehydrator that supplies a group of cases in which a plurality of cases are stacked to a rotating body and dehydrates the case group by rotating the rotating body (for example, Patent Document 1).
The centrifugal dehydrator of Patent Document 1 holds a rotating body having a turntable 4 and an openable / closable holder (4) that holds the four corners of a case group placed on the turntable 4 and rotates integrally with the rotating body. It is provided with two clamps 7) and a lever 40 (holder opening / closing mechanism) that is separated from the rotating body and arranged on the outer side thereof to open / close the holder.
In the centrifugal dehydrator of Patent Document 1, the other end of each lever 9 to which the clamp 7 is fixed at one end is prevented from opening the holder holding the case group when the rotating body is rotated (during dehydration treatment). A centrifugal pipe 8 as a weight is connected to. Then, when the rotating body rotates, a centrifugal force acts on the centrifugal pipe 8 as a weight, so that the four clamps 7 (holders) provided at the tip of the lever 9 are urged in the closing direction, thereby causing the holder. Is designed not to open.

However, in a lock mechanism that maintains the closed state of the holder (four clamps 7) by a weight such as a centrifugal pipe 8 like the dehydrator of Patent Document 1, when the weight of the article to be dehydrated is heavy or in a plan view. When a plurality of articles are held by the holder, a large load acts on the holder from the articles, so it is necessary to increase the urging force by the holder by increasing the weight.
In this case, as the weight increases, it is necessary to increase the rigidity of the device frame, etc., and increase the rating of the motor that is the drive source. Moreover, the acceleration time of the rotating body increases due to the increase in the rotational moment. There is also a problem that the deceleration time becomes long and the dehydration processing time becomes long.

In view of the above circumstances, the present invention moves between a rotating body that supports and rotates an article, a closed position that is provided on the rotating body and holds the article on the rotating body, and an open position that does not hold the article. A possible holder, a drive mechanism for rotating the rotating body, an opening / closing mechanism which is arranged separately from the rotating body to move the holder to a closed position and an open position, and the holder rotates in the closed position. In a centrifugal dehydrator equipped with a locking mechanism that keeps the holder in a closed position when holding an article on the body.
The lock mechanism is provided integrally with the rotating body, and allows an engaging position that engages with a holder in a closed position to prevent the holder from moving to an open position and a movement of the holder to an open position. It is characterized by including a lock member that can be moved to the release position and a release member that is disposed separately from the rotating body and moves the lock member at the engagement position to the release position. It is a thing.

According to such a configuration, even when the weight of the article or the quantity of the article in a plan view increases, it is not necessary to increase the weight, and a lock mechanism capable of reliably fixing the holder with a simple configuration is provided. be able to.

It is a top view which shows one Example of this invention, the left half of this figure shows the state which a holder is closed, and the right half of this figure shows a state which a holder is open. In the front view of FIG. 1, the left half of this figure shows a state in which the holder is closed, and the right half of this figure shows a state in which the holder is open.

Hereinafter, the present invention will be described with reference to the illustrated examples. In FIGS. 1 to 2, reference numeral 1 denotes a centrifugal dehydrator provided at the dehydration position A to simultaneously dehydrate a large number of cases 2. The centrifugal dehydrator 1 is a centrifugal dehydrator. A large number of cases 2 are dehydrated by rotating the two case groups 201 and 202 in which a plurality of cases 2 are stacked in a state of being mutually held together.
The cases 2 to be cleaned have a rectangular box shape with an open upper portion, and each case 2 is cleaned by a cleaning device on the upstream side (not shown) and then stacked in a predetermined number. Then, the case groups 201 to 20n in which the washed cases 2 are stacked in a predetermined number are carried into the centrifugal dehydrator 1 in a state where the two case groups (for example, 201 and 202) at the front and rear positions are mutually hugged. After being dehydrated, it is dehydrated.

The case groups 201 and 202 to be cleaned are carried into the rotary table 3 of the centrifugal dehydrator 1 via the inlet side carrier 4 on the adjacent upstream side by a pusher (not shown), and after the dehydration treatment. Case groups 201 and 202 are carried out from the rotary table 3 by the pusher via the outlet-side carrier 5 on the adjacent downstream side.

The drive mechanism 12 is composed of the motor 24, the pulleys 23 and 25, and the timing belt 26, and the operation of the motor 24 is controlled by the control device 15.
When the motor 24 is stopped, the control device 15 makes the rotary table 3 at the position shown in FIG. 1 via an encoder (not shown). As a result, the two case groups 201 and 202 can be carried in and out on the rotary table 3.
When the control device 15 drives the motor 24 during the dehydration work, the rotating shaft 21 is rotated. Therefore, the rotating table 3, the upper plate 17, and the shaking with the rotating shafts 21 and 22 as the rotation centers and supporting the case groups 201 and 202. The moving shafts 18A to 18D and the holder 6 (grip members 19A to 19D) are integrally rotated in the clockwise direction of FIG. During this dehydration operation, the four corners of the entire case groups 201 and 202 are held by the gripping members 19A to 19D constituting the holder 6, and the closed state (holding state) of the holder 6 is fixed by the lock mechanism 14. It has become.
Bearings 27A are attached to four places on the outer peripheral side of the upper surface of the rotary table 3, and bearings 27B are attached to both ends of the lower surface of the upper plate 17 so as to face the bearing 27A of the rotary table 3. The swing shafts 18A to 18D are rotatably supported while maintaining the vertical direction by the pair of bearings 27A and 27B facing each other in the vertical direction.
The distance between the swing shafts 18A and 18C on the left side (left side in the drawing) of the case 2 in the loading / unloading direction and the swing shafts 18B and 18D on the right side (right side in the drawing) in the loading / unloading direction is those. It is maintained at an interval that allows the two case groups 201 and 202 to pass between them with a margin.
When the rotary table 3 is stopped, the two swing shafts 18A and 18C on the left side and the two swing shafts 18B and 18D on the right side are stopped at positions along the loading / unloading direction. ing. In this state, the two case groups 201 and 202 can be carried in and out on the rotary table 3 without interfering with the swing shafts 18A to 18D.
A plurality of swing arms 28 are connected to a plurality of locations on the outer peripheral portion of each swing shaft 18A to 18D so as to be at the same position in the vertical direction. The gripping members 19A to 19D are connected to the tip so as to be in the vertical direction. The two pairs of left and right gripping members 19A to 19D constituting the holder 6 are composed of linear members having an L-shaped horizontal cross section, and the front surfaces of these four gripping members 19A to 19D are four places in the case group 201 and 202 as a whole. The case groups 201 and 202 are gripped by engaging with the corners of the case group 201 and 202.
The pair of left and right gripping members 19A, 19B and 19C, 19D are arranged so that their front surfaces (front surfaces) face each other, and when the swing shafts 18A to 18D are rotated by a required amount in the forward and reverse directions, they are provided. Since the swing arm 28 swings in the opening / closing direction, each pair of gripping members 19A, 19B, 19C, and 19D are opened and closed in the open position and the closed position in synchronization.
The gripping members 19A and 19B of the swing shafts 18A and 18B on the upstream side in the carry-in / out direction swing toward the center of the rotary table 3 from the upstream side, so that the two locations of the case group 201 are from the upstream side in the carry-in direction. It is possible to grasp the corner of the table. On the other hand, the gripping members 19C and 19D of the swing shafts 18C and 18D on the downstream side in the carry-in / out direction swing from the downstream side in the carry-in / carry-out direction toward the center of the rotary table 3 to become the downstream side. The two corners of the group 202 can be gripped. That is, the case groups 201 and 202 can be held on the rotary table 3 by the holder 6 composed of two pairs of gripping members 19A to 19D.

The base portion of the closing arm 31 is connected to the outer peripheral portion of the upper end of each of the swing shafts 18A to 18D at a position shifted by about 45 ° in the circumferential direction with respect to the swing arm 28. Further, the base portion of the opening arm 32 is connected to the outer peripheral portion of the upper end of each of the swing shafts 18A to 18D by shifting the position by about 180 ° in the circumferential direction from the closing arm 31.
The closing arms 31 and 31 connected to the swing shafts 18A and 18B are directed to the upstream side in the carry-in / out direction, and the closing arms 31 and 31 connected to the swing shafts 18C and 18D are in the carry-in / carry direction. It is directed to the downstream side.
The opening arms 32 and 32 connected to the swing shafts 18A and 18B are directed to the downstream side in the loading / unloading direction, and the opening arms 32 and 32 connected to the swing shafts 18C and 18D are directed to the loading / unloading direction. It is directed to the upstream side of. Therefore, the tips of the opening arms 32, 32 of the swing shafts 18A and 18C on the left side in the carry-in / out direction always overlap at the adjacent vertical positions, and similarly, the swing on the right side in the carry-in / carry direction. The tips of the opening arms 32 and 32 of the shafts 18B and 18D are always overlapped at adjacent vertical positions.

In this embodiment, the opening pusher 33 and the closing pusher 34 included in the opening / closing mechanism 13 swing the swing shafts 18A to 18D in the forward and reverse directions via the closing arm 31 or the opening arm 32. It is configured to open and close the holder 6 composed of two pairs of gripping members 19A to 19D.
The opening / closing mechanism 13 is provided on the upper part of the frame 7 on both the left and right sides along the loading / unloading direction so as to be separated from the rotating body 11 and sandwich the frame 7. That is, the opening / closing mechanism 13 includes air cylinders 36A and 36A horizontally connected to the frame 7 toward the two closing arms 31 and 31 on the left side in the loading / unloading direction, and the piston rods of these air cylinders 36A and 36A. The closing pushers 34 and 34 attached to the tip of the air cylinder 37, and the air cylinder 37 horizontally connected to the frame 7 toward the side of the tip of the two opening arms 32 on the left side in the loading / unloading direction. An opening pusher 33 attached to the tip of the piston rod of the air cylinder 37 is provided.
Further, the opening / closing mechanism 13 also has the same air cylinders 36A, 36A and 37 and the air cylinders 36A and 36A arranged on the left side in the loading / unloading direction on the right frame 7 sandwiching the rotating body 11. It includes closing pushers 34 and 34 attached to the tip of the piston rod and opening pusher 33 attached to the tip of the piston rod of the air cylinder 37.
The operation of the air cylinders 36A and 37 included in the opening / closing mechanism 13 is controlled by the control device 15, and the four air cylinders 36A located at opposite positions on both the left and right sides move forward and backward in synchronization with the control device 15. It is supposed to be done. In addition, since they are in opposite positions on both the left and right sides, they are moved forward and backward in synchronization.
In this embodiment, the control device 15 switches the operation of the air cylinders 36A and 37 as follows to open and close the holder 6 composed of the two pairs of gripping members 19A and 19D.
That is, in a state where the piston rods of the four air cylinders 36A stop at the retracting ends and the four closing pushers 34 on the left and right stop at the retracting ends and are separated from the closing arm 31, the pistons of the two left and right air cylinders 37 The rod is advanced from the retracted end to the forward end.
Then, the pair of left and right opening pushers 33 are advanced from the retracting end separated from the opening arm 32 to the advancing end. Along with this, the opening pusher 33 abuts on the tips of the two opening arms 32 from the outside, and then pushes them toward the center of the rotating body 11, thereby causing the swing arms 18A to 18D to swing. A total of four gripping members 19A to 19D (holders 6) are located at the most distant open positions from the center of the rotating body 11 via 28. That is, the gripping members 19A to 19D (holder 6) are opened (the state shown in the right half in FIGS. 1 and 2).
In the open state of the gripping members 19A to 19D (holder 6), the case groups 201 and 202 are carried in and out on the rotary table 3 via the gripping members 19A and 19C and 19B and 19D on both the left and right sides in the loading and unloading direction. can do.
On the other hand, when the case groups 201 and 202 are carried by pushers (not shown) onto the stopped rotary table 3 in the open state of the gripping members 19A to 19D, first, the piston rods of the left and right air cylinders 37 are moved from the forward ends. After being retracted to the retracted end, the piston rods of the four air cylinders 36A are advanced synchronously from the retracted end to the advanced end.
As a result, the opening pusher 33 retracts from the forward end to the backward end and separates from the opening arm 32, and the closing pusher 34 comes into contact with the closing arm 31 at the opposite position, which is inside the rotating body 11. Push it toward the side. As a result, the four gripping members 19A and 19B are synchronously swung toward the center of the rotating body 11 to the closed position via the swinging arm 28 of the swinging shafts 18A to 18D, and these four gripping members in total are swung to the closed position. The four corners of the entire case groups 201 and 202 are gripped by 19A to 19D (the state shown on the left side of FIGS. 1 and 2). That is, the holders 6 hold the case groups 201 and 202.
When the holder 6 is opened from the state where the gripping members 19A to 19D (holder 6) are in the closed position in this way, the four closing pushers 34 are retracted from the forward end to the backward end to close them. While separating from the arm 31, the two opening pushers 33 are advanced from the rear end end to the advancing end so as to come into contact with the opening arm 32, and then swing. As a result, the gripping members 19A to 19D (holder 6) are switched from the closed position to the open position and are located in the open position.
The opening / closing mechanism 13 opens and closes the holder 6 composed of the four gripping members 19A to 19D as described above, and the opening / closing mechanism 13 synchronizes the two pairs of closing arms 31 on both the left and right sides in the closing direction. By swinging, the four corners of the entire cases 201 and 202 on the rotary table 3 can be sandwiched and held by the gripping members 19A to 19D.

Further, in this embodiment, when the holder 6 composed of the gripping members 19A to 19D is closed and the rotating body 11 is rotated while holding the entire case groups 201 and 202 (during dehydration work), the gripping members 19A to 19A to A locking mechanism 14 is provided across the top plate 17 and the frame 7 to maintain the closed position of 19D.
The lock mechanism 14 includes a pair of lock bars 41, 41 arranged in the radial direction of the rotating body 11 on the upper surface of the upper plate 17, and a pair of air cylinders 43, 43 arranged vertically downward on the upper part of the frame 7. And a pair of left and right release pushers 42, 42 provided at the tip (lower end) of the piston rods of the air cylinders 43, 43 to switch the positions of the lock bars 41, 41.
The base 41B of the pair of lock bars 41 is located on the center side of the rotating body 11, and the tip 41A of the lock bar 41 is directed outward in the radial direction of the rotating body 11. Support pins 41C are projected on both left and right sides of the base portion 41B of the lock bar 41, and these support pins 41C are fitted into the engagement holes of the bracket 17A of the upper plate 17. As a result, both lock bars 41 can swing in the vertical direction with the support pin 41C as the swing center.
Since the tension spring 44 is attached over the upper end of the base 41B of the lock bar 41 and the center of the bracket 17A, the tips 41A of both lock bars 41 are always urged upward by the urging force of the tension spring 44. The entire lock bar 41 is horizontally supported by a stopper (not shown). Therefore, when the release pusher 42 is not in contact with the lock bar 41, the entire lock bar 41 is horizontally supported on the upper plate 17, and the tip 41A of the lock bar 41 is in the opposite position of the opening arm 32. It can come into contact with the inner side surface of the tip. When the tips of the two lock bars 41 are in contact with the side surfaces of the tips of the opening arms 32 that are opposite to each other, the opening arms 32 provided on the swing shafts 18A to 18D are held by the gripping members 19A to 19A. Since the 19D cannot be moved in the opening direction, the gripping members 19A to 19D (holder 6) are fixed at the closed position in the closed state.
Then, the lock bar 41 in the locked state in which the holder 6 is fixed in this way can be retracted to the lower side of the tip of the opening arm 32 by pushing down the tip side by the release pusher 42. ..
The operation of the air cylinder 43 is controlled by the control device 15, and the control device 15 raises and lowers the release pusher 42 via the air cylinder 43 when required.
When the piston rod of the air cylinder 43 is at the rising end, the release pusher 42 is separated from the lock bar 41 and stopped above the lock bar 41. In this state, the lock bar 41 is in a horizontal state on the upper plate 17. Moreover, the tip 41A engages with the side of the tip of the opening arm 32 which is adjacently opposed to the tip (the state shown in the left half of FIGS. 1 and 2).
That is, when the gripping members 19A to 19D (holder 6) are closed and the four corners of the entire case groups 201 and 202 are gripped and the release pusher 42 is in the raised position, the tip 41A of the lock bar 41 is pulled. The urging force of the spring 44 raises and engages with the tip of the opening arm 32 from the lower side. Therefore, the gripping members 19A to 19D are prevented from moving in the opening direction via the opening arm 32, the swing shafts 18A to 18D, and the swing arm 28 (the state shown in the left half of FIGS. 1 and 2). .. That is, the gripping members 19A to 19D in the closed position are fixed in the closed state.
On the other hand, when the release pusher 42 is lowered from the ascending end to the descending end from the locked state, the release pusher 42 abuts on the lock bar 41 and pushes it down, so that the tip 41A has been engaged until then. It retracts downward from the side of the tip of the opening arm 32 and abuts on the upper plate 17 (state shown on the right side of FIG. 2).
As a result, the tip of the opening arm 32 can move toward the rotation center side of the rotating body 11 via the upper side adjacent to the lock bar 41. That is, the locked state is released. In this released state, when the opening pusher 33 of the opening / closing mechanism 13 is advanced to the forward end, the opening arm 32 is swung toward the center side of the rotating body 11 by the opening pusher 33, so that the swing arm 28 The provided gripping members 19A to 19D (holder 6) can be switched from the closed position to the open position.
In this embodiment, the lock mechanism 14 is composed of a lock bar 41 arranged on the rotating body 11, an air cylinder 43 provided on the frame 7 on the fixed side, a release pusher 42, and a tension spring 44.

In the above configuration, the centrifugal dehydrator 1 performs the dehydration work of the case 2 as follows.
First, when the rotating body 11 is stopped, the release pusher 42 of the lock mechanism 14 is lowered to the lowering end, so that the lock bar 41 is pushed down by the release pusher 42 and the tip 41A hits the upper plate 17. I'm in contact. Then, the left and right opening pushers 33 of the opening / closing mechanism 13 are located at the forward ends and are pushed toward the center side of the rotating body 11 which is above the tip of the opening arm 32 and the tip of the lock bar 41, so that the grip member 19A ~ 19D (holder 6) is in the open position (the state shown in the right half of FIG. 1).
In this state, the case groups 201 and 202 in the joined state are carried onto the rotary table 3 at the dehydration position A by a pusher (not shown).
Then, the opening pusher 33 is retracted from the forward end to the backward end, and the closing pusher 34 is advanced from the backward end to the forward end. Further, the release pusher 42 of the lock mechanism 14 is raised to the original rising end and separated from the lock bar 41.
As the release pusher 33 retracts, the release arm 32 swings and moves outward from the tip 41A of the lock bar 41, so that the lock bar 41 urged by the tension spring 44 is pushed down. It rises from the raised state to the horizontal state and engages with the side surface of the opening arm 32 from the inside.
As a result, the gripping members 19A to 19D (holder 6) are in the closed position, the four corners of the entire case groups 201 and 202 are held by the holder 6, and the closed state of the gripping members 19A to 19D is fixed by the lock bar 41. NS.
When the case groups 201 and 202 on the rotary table 3 are held by the holder 6 and the closed state of the holder 6 is fixed by the lock mechanism 14, the entire rotating body 11 is rotated by the drive mechanism 12. As a result, the dehydration work of the case groups 201 and 202 is started. Then, when a predetermined time elapses after the motor 24 of the drive mechanism 12 reaches a predetermined rotation speed, the motor 24 is stopped, the rotating body 11 is stopped, and the dehydration work is completed.
During the dehydration operation, the closed state of the holder 6 is securely fixed by the lock bar 41 of the lock mechanism 14, so that the case groups 201 and 202 do not shift or fall off on the rotary table 3.
When the dehydration work is completed as described above, the locked state of the gripping members 19A to 19D (holder 6) by the lock mechanism 14 is released. That is, since the release pusher 42 of the lock mechanism 14 is lowered to the lowering end, the lock bar 41 is pushed down by the release pusher 42, deviates from the side surface of the release arm 32, and retracts to the lower side thereof. After that, while the closing pusher 34 of the opening / closing mechanism 13 is retracted to the retracted end, the opening pusher 33 is advanced to the advancing end to swing the opening arm 32, so that the gripping members 19A to 19D (holder 6) Is switched to the open position. That is, the holding states of the case groups 201 and 202 by the holder 6 are released.
After that, the dehydrated case groups 201 and 202 are carried out from the rotary table 3 by a pusher (not shown).
As described above, a large number of cases 2 are dehydrated by the centrifugal dehydrator 1 provided at the dehydration position A.

In the centrifugal dehydrator 1 of the present embodiment, the holder 6 (grip members 19A to 19D) is closed even when the weight of the case groups 201 and 202 and the quantity of the case group increase in a plan view. It is not necessary to add a heavy weight for maintenance, and it is possible to provide a locking mechanism 14 that securely fixes the holder 6 in the closed state with a simple configuration.

In the above embodiment, the case 2 is carried in and out of the rotary table 3 of the centrifugal dehydrator 1 in one direction from the adjacent upstream side to the adjacent downstream side of the dehydration position A. The case 2 may be carried in and out in this way. That is, the carry-in inlet and the carry-out outlet may be shared, and the case 2 may be carried in and out only from one side of the dehydration position A. In this case, when the configuration in which the case 2 is carried in and out of the dehydration position A from below is adopted in FIG. 1, the gripping members 19C and 19D on the upper side of the drawing may be fixed in the closed position.
Further, the swing shafts 18A to 18D may be configured to be urged by a spring in either the closing direction or the opening direction of the holder 6. That is, it may be configured as normally closed or normally open. In this case, the opening / closing mechanism 13 for opening / closing the gripping members 19A to 19D only needs to move the required member of the gripping members 19A to 19D to either the left or right side. , Air cylinders 36A and 37 can be omitted, and the configuration of the opening / closing mechanism 13 becomes even simpler.
