Description

[Detailed description of the invention] The present invention relates to a slat chain conveyor device, and more specifically, to a chain conveyor device that enables reciprocating conveyance of objects such as powder or granules using two surfaces of the slats. This is because it eliminates troubles such as the slats getting caught in the chain wheel that drives the chain and the slats colliding with each other, making it possible to move the slats reliably and stably and smoothly. An object of the present invention is to provide a slat chain conveyor device with excellent performance that can transport and discharge all conveyed objects on the slats without causing them to remain attached to the slats.

For this purpose, the present invention provides shafts protruding at required intervals inside each chain suspended in parallel on the left and right through a driving chain wheel having a boss portion and a driven chain wheel having a boss portion. A slat is pivotally attached to each shaft between the shafts so as to be freely rotatable, and the slats are held horizontally on the side end surfaces of the planar trapezoidal portions formed on both sides of these slats and slightly toward the front. Rectangular support plates with four arcuate corners are provided orthogonally to allow the chain to move forward, and a pair of left and right upper guide plates are provided on the forward side of the chain for sliding the support plates to move the slats horizontally. One end of the chain is placed close to the boss of the driven chain wheel, and the other end is placed horizontally apart from the driving chain wheel, and on the return side of the chain, a support plate slides into contact with the slats. A pair of left and right lower guide plates are arranged horizontally with one end positioned slightly behind the driving chain wheel and the other end spaced apart from the driven chain wheel. Below each upper guide plate and at a required distance from the other end, there is a cross-sectional shape where the support plates of the slats rotated as the chain moves forward and collide vertically. The slat is tilted horizontally together with a locking plate and a support plate which is provided integrally with the locking plate and whose free end is located close to the boss portion of the drive chain wheel and rides on the locking plate. A guide plate is provided to guide the drive chain wheel to the host section.
Furthermore, below each lower guide plate and at a required distance from the other end, there is a cross-sectional ``shaped engagement'' where the support plate of the slat that rotates with the return movement of the chain collides in a vertical state. It is characterized by a configuration in which a stop plate is provided.

Hereinafter, the present invention will be explained based on illustrated embodiments.

1 has a boss portion 2, and a drive source such as a motor (not shown)
3 is a drive chain wheel rotationally driven by a boss portion 4.
These chain wheels 1 and 3 have a casing 5
A chain 6 is suspended in parallel between the left and right sides between the chain wheels 1 and 3, and the chain 6 reciprocates through the rotation of the chain wheels 1 and 3.

As shown in FIG. 1, the chain 6 includes a pair of roller link plates 7.7 disposed facing each other on the inside, and a pair of roller link plates 7.7 disposed facing each other on the outside between the roller link plates 7.7. It is composed of a pair of pin link plates 8, 8, and a roller 10 rotatably supported by a pin 9 at the connecting portion of these plates, and these chains 6
．． 6, shafts 11 are protruded at required intervals.

In this embodiment, the shaft 11 is provided for each roller 10 and on an extension of the pin 9, as shown in FIG. It can be installed protrudingly as a.

In Fig. 1, reference numeral 12 denotes a slat on which objects to be conveyed, such as powder or granules, are placed and conveyed, and one end of the slat has a cylindrical base 1
3, and both end portions in the transverse direction include a planar trapezoidal portion 16 that is closer to the front and is folded by a notch portion 14 that extends to the end of the base portion 13 and a notch portion 15 that continues to the front end.
This slat 12 has a cylindrical base 13
A washer 17 is placed at the tip of the corresponding shaft 11 at both ends of the
The split pin 18 is inserted through the washer 17 so that it can rotate freely, and is prevented from being pulled out by a split pin 18 that is inserted in the diametrical direction of the shaft 11 at the front of the washer 17.

Support plates 19 are orthogonally fixed to the side end faces of the planar trapezoidal portions 16 at both ends of the slat 12 by means such as welding, for slidingly contacting and standing upright on a guide plate, which will be described later, and holding the slat 12 horizontally. This support plate 19 has a trapezoidal portion 1
It is made of a rectangular plate with the same width as the length of 6, and its four corners are formed in an arc shape, so that it can smoothly slide on the locking plate and guiding plate, which will be described later. This allows for smooth movement of the vehicle onto parts 2 and 4.

A pair of left and right upper guide plates 20 are arranged on the outbound side of the chain 6.

As shown in FIG. 7, this guide plate 20 is for slidingly contacting the support plate 19 to move the slat 12 horizontally.
As shown in FIGS. 4 and 7, the one end portion 21, which is slightly curved downward and has a narrow width, is located close to the boss portion 4 of the driven chain wheel 3, and does not interfere with the driven chain wheel 3. The other end portion 23 of the portion 22, which has become wider than the portion 22, is horizontally arranged so as to be separated from the drive chain wheel 1 by a required distance, and in the longitudinal direction of the upper surface of the portion 22, a strip along which the rollers 10 of the chain 6 are guided is provided. A rail 24 is provided.

The one end portion 21 of the upper guide plate 20 is slightly curved downward and is located close to the boss portion 4 of the driven chain wheel 3 in order to smoothly guide the support plate 19 of the slat 12 that is moving back. This is to make it ride on the board 20.

In this embodiment, rails 24 are provided on the upper guide plate 20 and the lower guide plate to be described later, but this is because the rollers 10 of the lever chain 6 are smaller than the plates 7.8.
If the rollers are larger than the plates 7.8, the rails 24 are not needed, since the jig rotates on a guide plate.

A pair of left and right lower guide plates 25 are arranged on the return path side of the chain 6.

As shown in FIG. 7, this lower guide plate 25 is for slidingly contacting the support plate 19 of the slat 12 that has been moved and causing the slat 12 to move back horizontally. Its one end 26 is located slightly behind the driving chain wheel 1, and the other end 27 is arranged horizontally with a required distance from the driven chain wheel 3. Similarly, a single rail 24 is provided.

At a portion below each upper guide plate 20 and having a required distance from the other end portion 23 (a distance slightly longer than the width of the slat 12 in the lateral direction), as shown in FIG. 4 and FIG. As shown, the slat 1 rotates as the chain 6 moves forward.
A locking plate 28 having a cross-section shaped like ``2'' collides with the support plates 19 of 2 in a vertical state; A narrow guide plate 29 is disposed close to the guide plate 29 .

As shown in FIG. 7, this locking plate 28 collides with the support plate 19 at a position rotated approximately 90 degrees when the slat 12 passes the other end 23 of the guide plate 20 and rotates in the direction of the arrow. This prevents the slats 12 from colliding with each other by locking them and preventing further rotation, in other words, reversal, and also gives vibration to the slats 12 through the collision of the support plate 19 to prevent them from adhering to the slats 12. The guide plate 2 is used to transport and discharge all the objects on the slats 12 without leaving them behind.
As shown in FIG.
This is to prevent jamming with the drive chain wheel 1 by tilting it horizontally and guiding it to the boss part 2.

5 and 7 below each lower guide plate 25 and at a required distance from the other end 27 (a distance slightly longer than the width of the slat 12 in the lateral direction). As shown in FIG. 2, a locking plate 31 having a cross-section of "2" is disposed with which the support plate 19 of the slat 12 rotated with the backward movement of the chain 6 collides in a vertical state. It has the same function as the locking plate 28.

Next, the operation of the present invention will be explained.

As shown in FIG. 7, when the chain 6 moves (forward movement) in the direction of arrow A through the rotational drive of the chain wheels 1 and 3, the slat 12 on the upper side (outward path side) is moved from the support plate. Since the guide plate 19 comes into sliding contact with the upper surface of the upper guide plate 20, it moves in the same direction while maintaining the horizontal position.

Then, at the same time that the free end of the slat 12 passes the other end 23 of the upper guide plate 20, the slat 12 rotates in the vertical direction (in the direction of the arrow) using the shaft 11 as a support.
The objects to be conveyed, such as powder and granular material loaded on the upper surface (front surface), are dropped onto the upper surface (back surface) of the slats 12 on the return side, and the supporting plate 19 of the rotated slat 12 is held in a substantially vertical state by the locking plate 28. The slats 12 are vibrated to completely drop the conveyed objects remaining on the slats 12 by colliding with the slats 12 to prevent further reversal.

Next, the slat 12 that collided with the locking plate 28
8, rides on the guide plate 29, moves in an orderly manner on the guide plate 29 while tilting horizontally through the sliding contact of the arcuate corner of the support plate 19, and is guided to the boss part 2 of the drive chain wheel 1. As the chain wheel rotates, the slat 12 rotates in the direction of the arrow, and is held horizontally again by the support plate 19 relative to the lower guiding plate 25, moving in the two directions of the arrow (backward movement), and the free end of the slat 12 moves downward. At the same time as it passes the other end 27 of the guide plate 25, the slat 12 rotates again in the vertical direction (in the direction of the arrow H), causing the object to be transported on the slat 12 to fall, and the supporting plate of the rotated slat 12 The slat 19 collides with the locking plate 31 in a substantially vertical state to prevent further reversal, and the slat 1
2 is vibrated to completely drop the conveyed objects remaining attached to the slats 12.

Next, the collided slat 12 rides on the locking plate 31, gets off, is guided to the boss part 4 of the driven chain wheel 3 in a vertically suspended state, and is placed on one end part 21 of the upper guide plate 20. Climb aboard and proceed in the same manner.

Since the present invention has the above-mentioned configuration, for example, as shown in FIG. If carried out, the material is conveyed from the input port A to the opposite end using the upper slat 12 (outgoing route side), and the slat 12 is rotated vertically at the end to transfer the material to the lower side (returning route side) slat 12. This allows the conveyor to be dropped onto the top, and then conveyed one after another and discharged from the discharge port C, allowing one conveyor to perform the functions of two conveyors and making maximum use of the space inside the drying chamber. , miniaturization becomes possible.

As is clear from the above description, according to the present invention, the support plates 19 provided at both ends of the slat 12 are rectangular plates with four arcuate corners. The inclination movement is performed smoothly and stably, and the section below the upper guide plate 20 and having a required distance from the other end 23 has a cross section of
A guide plate 29 is provided which is integrally connected to the lock plate 28 and whose free end 30 is close to the boss portion 2 of the drive chain wheel 1. A locking plate 31 having a "shaped cross section" is provided below the slat 25 and at a required distance from the other end 27, so that when the slat 12 rotates in the vertical direction, the support plate 31 19 collides with the locking plates 28 and 31 in a vertical state, preventing the slat 12 from reversing any further and colliding with other slats 12. In addition, the slat 12 is vibrated and adheres to the slat 12. This allows the remaining objects to be completely removed.

Further, the guide plate 29 allows the slat 12 that has climbed onto the locking plate 28 to be tilted horizontally and move in an orderly manner, and is prevented from being caught in the drive chain wheel 1, thereby preventing the slat 12 from riding on the locking plate 28. 2, the vehicle moves reliably and smoothly on the return journey.

In summary, according to the present invention, the reciprocating conveyance of the conveyed object can be ensured by using the front and back surfaces of the slat, and can be carried out smoothly without leaving the object remaining on the slat.
