Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oscillating sorting apparatus that supplies a granular material on a sorting plate and classifies the granular material.

Conventional technology and its problems Conventional rocking sorters generally have a cam mechanism mounted on a rotating shaft or a rotating shaft formed on a crank, and one of a connecting rod is rotatably connected to the cam mechanism or the crank. It is customary to classify the granular material with the sorting plate by reciprocatingly swinging the swinging frame with the sorting plate attached and connected in connection with the swinging frame that is swingably supported on the other side. .

By the way, since a reaction force corresponding to the weight of the oscillating frame, granular material, etc. is applied to the rotating shaft each time the oscillating frame reciprocates, a balance weight for offsetting the weight of the oscillating frame, etc. is provided on the rotating shaft. Although a process that does not transmit vibration and impact to the machine frame with the shaft attached and the rotating shaft mounted is taken, the weight of the swing frame and the balance weight are limited because the size of the balance weight is limited. They do not always match, and therefore, it is necessary to give the machine frame, the rotating shaft, and the connecting rod sufficient strength, which raises the cost. In other words, the drive unit receives all the impact accelerated by the weight of the oscillating body when the oscillating body returns, so that the impact propagates to the machine frame via the rotating shaft, and the entire sorting machine vibrates. And reduce the sorting performance,
This may cause damage to the connecting rod or the swing frame. Even if the swing frame and the balance weight are equal, the vertical load has not been eliminated, so if the swing sorter is installed at a high place such as a stand, Unless it is made to be rugged, the swinging sorter vibrates up and down, and there is a problem that satisfactory performance cannot be secured due to a decrease in swinging operation.

SUMMARY OF THE INVENTION The object of the present invention is to improve the above-mentioned problems of the prior art, reduce the impact caused by the rocking motion as much as possible, maintain the sorting performance with high accuracy for a long time, and reduce the cost thereof. ,
Further, it is another technical object of the present invention to provide a swing sorting device that does not require any special restriction on installation of the device.

Measures to solve the problem Take the following technical measures.

Arrange the oscillating frame with the sorting plate and the driving device,
The swing frame is supported by a leaf spring and can swing back and forth.

The swing frame is provided with a passive section, the driving device is provided with a swing section, and the swing section pushes the passive section to reciprocate the swing frame back and forth.

The position of the swinging portion relative to the passive portion is such that the forward movement start position of the action stroke performed by the swinging portion is behind the final end position of the passive stroke of the passive portion including the inertial movement when the swinging frame returns. It is said.

The action stroke of the swinging motion portion is set to be larger than the facing distance between the swinging motion portion and the passive portion when the swinging frame is stopped.

Action When the drive device is started, the swinging portion repeatedly reciprocates back and forth with its action stroke. The passive portion provided on the swing frame moves forward in the reciprocating stroke of the swinging portion, and moves backward together with the swinging portion by the force of the leaf spring in the reciprocating stroke. Thereby, the swing frame reciprocates back and forth. When reciprocating, a large impact is likely to occur when the direction of movement of the swing frame is reversed,
In this case, at the end of the reciprocating stroke, the swinging frame moves a little further forward due to inertia even when the swinging motion reaches the front turning point of the stroke, so that the passive portion and the swinging motion are separated from each other. Occurs. At the end of the return stroke, the swinging portion moves rearward of the passive portion at the rear end of the swing frame, so that the swinging portion is separated from the passive portion, and a space is created. The position of the passive portion at this time is a position including the backward movement due to the inertia of the swing frame. The impact caused by the weight of the swing frame and the like due to the reciprocating swing of the swing frame acts only at the moment when the operating portion comes into contact with the swinging portion, but it is light and has no special effect on the drive device. . Therefore, the drive device and the machine frame can be reduced in size, the inertia due to the vertical load generated in the swing frame is small, and the place where the swing sorting device is provided is not restricted.

Therefore, the granular material supplied to the sorting plate is subjected to accurate swinging operation, so that high-precision sorting and sorting can be performed for a long period of time, and there is an effect that the durability of the driving device, the swinging frame and the like can be improved. .

Embodiment FIG. 1 to FIG. 3 show an embodiment (embodiment A) of an oscillating sorting apparatus A that sorts a granular material into large grains.
The spring receivers 6, 6, 7, 7 are fixed to the lower part of both side walls 2, 3, and the upper surface and one side of the rectangular box are opened.
9, 10, 11 are erected to form a swing frame 12, and spring mounts 13, 13, 14, 14 are attached to side frames 9, 11 of the swing frame 12,
One end of the leaf springs 15 is attached to the spring receivers 6, 6, 7, 7, and the other end of the leaf springs 15 is attached to the spring mounts 13, 13, 14, 14, and the swing frame 12 is mounted. An elastic body such as rubber having high abrasion resistance is attached to the side frame 10 of the swing frame 12 so as to be swingably supported, and is formed in the passive portion 16 which receives the swing operation. The guide rails 17 and 18 are fixed on the wall surface, the perforated wall sorting plate 19 is mounted on the guide rails 17 and 18, the particulate matter discharge port 21 is fixed on the opening 20 of the swing frame 12, and the bottom plate 8 is fixed. A discharge port 22 for small particles is attached to the particulate matter discharge port 21 side, and the discharge ports 21 and 22 are connected to the side wall 5 of the machine frame 1.
Protruding from the opening.

The driving device 23 disposed on one side of the machine frame 1 is formed as follows. Guides 30, 30 for guiding the drive unit frame 26 back and forth are fixed to frames 24, 25 which are mounted laterally on the bottom of the machine frame 1 and fixed to the side walls 2, 3, respectively, and connected to both side plates 27A, 27B. Board
28, 29 are connected to form an integral drive frame 26,
Restrictors 31, 31 are fixed to the outer portions of 7A, 27B, and are fitted and inserted into guide tables 30, 30, so as to be movable. Cam 32 between both side plates 27A, 27B
The rotation shaft 33 on which the shaft is mounted is rotatably mounted horizontally,
A pendulum 35 is mounted on a rotating shaft 36 rotatably mounted on both side plates 27A and 27B (FIG. 1), and one end of a connecting rod 38 is supported on a bearing 37 protruding from the pendulum 35. Then, the cam fitting portion 39 formed at the other end of the connecting rod 38 is divided into a mounting portion 39A and a cover 39B, and the cam 32 is mounted, and both ends of the mounting portion 39A and the cover 39B are bolted. Has been concluded. The position of the oscillating portion 34 with respect to the passive portion 16 is determined by determining whether the forward movement start position of the action stroke performed by the oscillating portion 34 includes the inertial movement when the oscillating frame 12 returns (moves backward). It is located behind the rearmost position of the 16 passive strokes. Further, the swing stroke of the swinging portion 34 is set to be larger than the facing distance between the swinging portion 34 and the passive portion 16 when the swinging frame 12 is stopped.

The electric motor 41 with the drive wheel 42 mounted on it is mounted on the side plate 27A, and the belt 44 is wound around the passive wheel 43 and the drive wheel 42 mounted on the rotating shaft 33, and screws are screwed on the inner tube surface. Pipe 45
(FIG. 1) is fixed to the machine frame 4 and screwed on a pipe 45 to form a screw rod 46.
One end is rotatably locked to the connecting plate 29 of the drive unit frame 26,
A nut 48 of the screw rod 46 is inserted, and the other end of the screw rod 46 is protruded from the machine frame 4 to attach a handle 47 to the shaft. The frame 26 is moved back and forth to adjust the distance D between the swinging portion 34 and the passive portion 16 formed on the side frame 10 of the swinging frame 12. A hopper provided on the swing frame 12.

The operation of the above embodiment will be described below. When the electric motor 41 is started to rotate the rotating shaft 33, the eccentric rotation of the cam 32 is interlocked with the pendulum 35 via the connecting rod 38. The pendulum 35 moves back and forth with the rotation shaft 36 as a fulcrum. When the pendulum 35 moves forward and the swinging portion 34 comes into contact with the passive portion 16, the swinging frame 12 is moved from the stationary state to the pressed state by the leaf springs 15 supporting it, and the swinging frame 12 is moved. Is pushed forward. When the passive unit 16 reaches the position where it is maximally pressed, the swinging unit
34 does not move forward from that position, but passive
16 moves slightly forward due to the inertia of the swing frame 12, and a slight space is created between the swing frame 12 and the swinging portion 34. When the swinging portion 34 moves backward from this point, the passive portion 16 receives the force (repulsive action) of the leaf springs 15 attached to the swinging frame 12 until a certain point. 34
However, since the forward movement start position of the action stroke performed by the swinging portion 34 is set to be behind the rearmost position of the passive stroke performed by the passive portion 16, the swinging portion
When the rearward movement of 34 reaches a certain point, the passive portion 16 and the swinging portion 34 separate from each other, and a space is created between the swinging portion 34 and the passive portion 16. The oscillating frame 12 comes to a standstill state only for a moment at the last end position of the passive stroke. However, the oscillating portion 34, which has entered the reciprocating stroke shortly after the oscillating frame 12 is at rest, comes into contact with the passive portion 16, and the oscillating frame 12 receives the pressing action again.

As described above, the swinging portion 34 and the passive portion 16 are repeatedly brought into contact with and separated from each other, and the swinging frame 12 is caused to swing back and forth.

As described above, when an impact occurs in which the swinging frame 12 reverses the moving direction, the passive portion 16 of the swinging frame 12 and the swinging portion 34 of the driving device 23 are separated from each other. The impact caused by the weight is completely unrelated to the drive device 23 and the machine frame 1 side. In addition, the swinging portion 34 is a passive portion.
When the swinging direction is reversed, the contact between the passive portion 16 and the swinging portion 34 is gently brought into contact with the swinging portion 34 in the return stroke or the forward stroke. Does not occur.

Therefore, the driving device 23 can transmit the swing smoothly without causing vibration to the entire sorting machine and reducing the sorting performance or damaging the rotating shaft 33, the connecting rod 38, the swing frame 12 and the like. The operation can be continued, and the configuration of the driving device 23 can be reduced in size and simplified.

As described above, when the granular material of large and small sizes is supplied from the hopper 50 opened by pulling the shutter 49, the granular material is supplied to the upper surface of one side of the perforated wall sorting plate 19 attached to the swing frame 12 which is continuing the reciprocating swing. The object is subjected to the swinging operation on the perforated wall sorting plate 19, is conveyed forward, and is taken out from the particulate matter discharge port 21. In the course of this transport operation, the small particles fall through the through holes of the perforated wall sorting plate 19 and fall on the bottom plate 8, and the small particles move on the oscillating bottom plate 8 and are taken out from the small particle discharge port 22. You.

During the sorting operation by the swinging of the perforated wall sorting plate 19, small particles close to the through holes of the sorting plate 19 are fitted into the through holes and instantaneous clogging occurs, but the swinging frame 12 moves in the moving direction. When reversing, a large impact is generated, and the impact generates vibration in the perforated wall sorting plate 19 and ejects small particles clogged in the through hole. Particle sorting and clogging prevention effects can be obtained, and a high-precision sorting operation can be stably performed for a long time.

The slight amplitude of the reciprocating swing of the swing frame 12 can be adjusted by loosening the nut 48 and operating the handle 47 to
This can be performed by adjusting the distance D between the swinging portion 4 and the passive portion 16 of the swinging frame 12 by moving the swinging back and forth. When the adjustment is completed, the nut 48 locks the rotation of the screw rod 46. When the swing amplitude of the swing frame 12 is changed in accordance with the type of the granular material or the sorting purpose, the connecting rod 38
Remove the cover 39B from the mounting part 39A, and
A, 27B, replace it with one with a different eccentricity of the cam 32, attach the both side plates 27A, 27B again, attach the cam 32 to the cam fitting portion 39 of the connecting rod 38, and move the drive unit frame 26 back and forth. The distance D between the swinging movement part 34 and the passive part 16 of the swinging frame 12
To adjust. Further, the perforated wall sorting plate 19 is also pulled out from the guide rails 17 and 18 of the swing frame 12 for the purpose of sorting the granular material, and a through hole of the perforated wall sorting plate 19 is selected and mounted. It is to be noted that the perforated wall sorting plate 19 may be provided in multiple stages with different through holes, or a bottom plate may be provided for each and a supply unit may be individually provided, and the perforated wall sorting plate 19 may be multi-staged. Can be implemented.
