The drawings show one embodiment of the present invention, and the configuration thereof will be described with reference to the drawings. 1 is a side view of a conveyed product H of a granular material such as brown rice, brown rice, white rice, red beans, and a leaf-like body (stems and leaves) such as tea leaves. It is a machine casing of a transport device for feeding and transporting, and is configured by providing side plates 3 on both the left and right sides of the bottom plate 2 and the bottom plate 2. The machine casing 1 is formed long in the transport direction, and a supply unit 5 is provided above the start end of the machine casing 1, and the supply unit 5 is configured with an inlet 7 at the top and a supply port at the bottom. A discharge unit 10 having a drop port 8 is provided at the end of the machine casing 1.
In the machine casing 1, a transport conveyor 11 that transports the transported material H supplied from the supply unit 5 to the discharge unit discharge unit 10 is provided. In this case, the transport direction of the transport conveyor 11 is expressed as the front-rear direction, and the transport conveyor 11 mounts the driven sprocket 12 in the machine casing 1 behind the supply port by the driven shaft 13. A drive sprocket 14 is mounted by a drive shaft 15 at a predetermined position on the front side in the transport direction beyond the drop port 8 of the discharge unit 10 in the machine casing 1. A chain 17 having a carrier 16 is hung between the driven sprocket 12 and the drive sprocket 14.

As shown in FIG. 3, the chain 17 is formed in an endless manner by connecting both side links 18 in the front-rear direction with pins 19, and the left and right sides of a predetermined one of the side links 18 intersect with the traveling direction. A projecting portion 20 that projects is provided, and the projecting portion 20 constitutes the transport body 16. An elastic scraping body 21 made of urethane rubber or the like is attached to each protruding portion 20 of a specific transport body 16 with a predetermined number of the transport bodies 16. Reference numeral 22 denotes a fixture.
The elastic scraping body elastic scraping body 21 is configured to move in sliding contact with the upper surface of the bottom plate 2 of the machine casing 1. Further, the elastic scraping body 21 is configured to move in proximity to or in sliding contact with the left and right side plates 3 of the machine casing 1.
Reference numeral 22 denotes a prime mover, which is installed on the upper end surface of the machine housing 1 in FIG. 1 and installed in the machine housing 1 in FIG. Reference numeral 23 is a transmission chain, and 24 is a tension sprocket.
Conventionally, since the state of the fall of the conveyed product from the dropping port 8 is not conscious, in order to convey the conveyed product to a plurality of conveying paths, a plurality of discharge portions are formed in the conveying direction of the machine casing 1, An opening / closing shutter was provided at the outlet of the discharge unit, and the opening / closing shutter was opened and closed.

The drop port 8 of the discharge unit 10 has a predetermined length in the transport direction so that the receiving ports 31 of the plurality of distribution baskets 30 of the distribution unit 29 provided below the discharge unit 10 are provided, and the drop port 8 The conveyed product H is configured to fall substantially evenly from the start end to the end.
The distribution unit 29 distributes the conveyed product H toward the conveyance path to the next process K such as a color selection process in which defective products are selected and removed from the dropping port 8 by the distribution basket 30 or a weighing bag filling process.
Any means for evenly dropping from the start end portion to the end end portion of the dropping port 8 is optional, but as an example, a bridge phenomenon (hereinafter referred to as bridge B) intentionally generated in the transported object H transported by the transport body 16. , A part of the conveyed product H is dropped at the start end of the drop port 8 of the discharge unit 10, but the rest of the transported product H is allowed to pass through and is transported substantially evenly from the start end to the end of the drop port 8. The object H is configured to drop.

In order to facilitate understanding, the bridge B is schematically illustrated in FIGS. 7 to 9 but does not necessarily match the actual state, and the configuration of the present invention is limited by these illustrations. is not.
The configuration in which the bridge B is intentionally generated in the transported object H being transported by the transporter 16 is different depending on various conditions such as the properties of the transported object H, and is arbitrary. The distance between the side plates 3 is set such that the layer thickness, which is the thickness of the layer of the transported object H transported by the transporter 16, is equal to or greater than a certain value while taking into account the transport amount of the transported object H.
That is, the layer of the conveyed product H supplied by the supply unit 5 is bulky and air is mixed therein and the bulk density is “rough”, but the conveyed product H is entangled and tightened while being conveyed to the discharge unit 10. the layer thickness becomes thinner bulk density becomes "dense", if the thickness of that thin is "dense" is made to be a thickness of conveyed object H in the starting end of the fall opening 8 constant or The bridge B is intentionally generated in the conveyed product H above the start end of the dropping port 8.

In addition, as a configuration in which the drop port 8 is uniformly dropped from the start end portion to the end end portion, the left and right widths of the left and right side plates 3 are narrower than the left and right widths, and a part of the drop port 8 is narrowed, and a part of the conveyed product H is dropped. Is configured to allow the remaining transported object H to pass through and drop substantially uniformly from the start end to the end of the drop port 8.
In addition, forming the width of a part of the drop opening 8 to be narrower than the left and right width of the left and right side plates 3 also effectively works to maintain the state of the bridge B, as will be described later.
The left and right widths of the start end of the drop port 8 are narrower than the left and right widths of the left and right side plates 3 of the machine casing 1 and are formed in the start end side opening 35.

The bottom plates 2 on the left and right sides of the start end side opening 35 are formed in the start end side receiving plate portion 34. The start end side receiving plate portion 34 supports the left and right sides of the conveyed product H above the start end portion of the start end side opening portion 35, and assists the intentional bridge B to pass above the center portion of the start end side opening portion 35. And the transport path forming action of transporting the transported object H on the start side receiving plate part 34 on the lower side.
For this reason, the start end side opening 35 and the start end side receiving plate portion 34 can suppress the amount of fall of the conveyed product at the start end of the drop port 8 and improve the dispersion drop effect.
The start end side opening 35 and the start end side receiving plate portion 34 have a predetermined length in the transport direction and are formed to have substantially the same width from start to finish.

In other words, the opening 35 on the start end side simply narrows the opening area in advance in order to suppress the amount of fall of the transported object at the start end of the dropping port 8 and to transport a sufficient amount of the transported object H to the lower transport side. In addition, the start end side opening portion 35 and the start end side receiving plate portion 34 have a predetermined length in order to maintain a state in which the fall amount is prevented from being dropped at the start end side opening portion 35 with respect to the transport amount for a certain period of time. Over the entire length, it is formed with substantially the same width throughout.
Next, the end side of the drop port 8 is formed in the end side opening 36 which is opened over the entire length in the same length as the left and right side plates 3 of the machine casing 1 over a predetermined length.

Since the entire end opening 36 of the drop opening 8 is opened, all the transported objects H transported to the end opening 36 can be dropped at the end of the drop opening 8 and the remaining transport in the machine casing 1 can be carried out. The product H is not generated.
An intermediate opening 38 is provided between the start end opening 35 and the end opening 36. The starting end of the intermediate opening 38 is connected to the terminal end of the starting end opening 35, and the terminal end of the intermediate opening 38 faces the starting end of the terminal opening 36.
Therefore, the intermediate opening 38 has the same left and right width as the start end opening 35 at the start end, and the end of the intermediate opening 38 is formed to have a slightly narrow left and right width than the end opening 36. The width of the portion 38 is gradually increased from the start end to the end.

The bottom plates 2 on both the left and right sides of the intermediate opening 38 are formed in the intermediate receiving plate 39. The intermediate receiving plate portion 39 has the same width as the starting end side receiving plate portion 34 and the intermediate receiving plate portion 39 so that the end portion of the intermediate receiving plate portion 39 is connected to the starting end portion of the terminating end opening 36. 39 is configured such that the lateral width gradually becomes narrower from the start end to the end.
The intermediate receiving plate portion 39 supports the conveyed product H above the intermediate opening 38 from the left and right sides, and uses the intermediate receiving plate portion 39 as a conveying path to secure the amount of falling on the lower side, thereby achieving a distributed dropping effect. Improve.
That is, the drop port 8 is set to a predetermined length so that a plurality of distribution rods 30 can be provided in advance, and the conveyed product is substantially evenly distributed from the start end to the end of the drop port 8 by the drop port 8 and the left and right receiving plate portions 34. Since H falls, it is only necessary to provide each receiving port 31 of the distribution basket 30 below the falling part, and open the dropping port 8 further to the lower conveyance side from the part where the dropping actually ends, and the remaining conveyed product It is configured not to generate H.

Therefore, each receiving port 31 of the plurality of distribution baskets 30 is provided, but the length of the receiving port 31 at the end is different from the length of the other receiving ports 31, and the terminal end of the terminal receiving port 31 and the terminal end of the dropping port 8 are different. The end of the side opening 36 is aligned with the end of the side opening 36 so that the remaining transported material H is not generated in the machine casing 1.
A connecting portion 40 in the left-right direction that connects the left and right bottom plates 2 is provided at a substantially middle position in the transport direction of the drop port 8. The connecting portion 40 is formed by a part of the bottom plate 2 and connects the bottom plates 2 on both the left and right sides of the intermediate opening 38. Therefore, the connecting part 40 is expected to ensure the rigidity of the machine casing 1 and suppress the twisting and distortion of the machine casing 1.
The terminal opening 36 is provided with a pair of narrow left and right supports 41. The support body 41 is formed by a part of the bottom plate 2, and the start end portion is located immediately inside the start end portion of the end-side opening 36, and the distance between the two ends narrows toward the end side.

The support body 41 supports the transport body 16 that passes over the terminal opening 36 and prevents the transport body 16 from falling.
As an example of a specific configuration of the embodiment, about 1 ton of tea leaves per hour are supplied to the supply unit 5 of the machine casing 1, the transport body 16 moves at a speed of about 12 cm per second, and the start side opening 35 is opened. About 50 to 70 mm in width, 140 to 160 mm in opening length, 180 to 210 mm in opening length to the connecting portion 40 of the intermediate opening 38, 80 to 95 mm in the opening width of the intermediate opening 38 in this part, The front-rear width of the connecting portion 40 is about 20 to 30 millimeters, the opening length from the connecting portion 40 to the end of the intermediate opening 38 is 130 to 160 millimeters, the opening width of the intermediate opening 38 in this portion is 90 to 95 millimeters, The opening width of the terminal side opening 36 is about 130 to 140 mm and the opening length is 180 to 21 mm.

The dropping port 8 of the embodiment is formed in the discharge unit bottom plate 45 of the discharge unit 10, and the discharge unit bottom plate 45 is detachably attached to the machine casing 1 part of the discharge unit 10.
Accordingly, when the opening 8 having a different opening width or opening length is appropriately selected and attached, the machine casing 1 can be made to handle the distribution and transportation of other types of transported objects H.
Similarly, the distribution unit 29 is configured to be detachable from the discharge unit 10 and is configured to be able to change the number of distributions by changing the number of receiving ports 31.
Therefore, in FIG. 6, the receiving port 31 of the distribution unit 29 is not specifically illustrated, but 2 to 5 receiving ports 31 and the distribution basket 30 are provided from the start end portion of the dropping port 8 to the lower end portion. Just do it.
In FIG. 4, in order to facilitate understanding, a side view of the distribution basket 30 of the distribution unit 29 is shown as an example in a plan view.
Further, for ease of understanding, the bottom plate 2 of the machine housing 1 and the discharge portion bottom plate 45 of the discharge portion 10 are separately shown, but the discharge portion bottom plate 45 of the discharge portion 10 constitutes the bottom plate 2 of the machine housing 1. To be part of.

(Operation of Example)
Next, the operation will be described.
When the motor is energized, the drive sprocket 14 rotates, and the drive sprocket 14 rotates the chain 17 to move the carrier 16 from the start end of the machine casing 1 to the end.
In this state, when the conveyed product H is supplied to the input port 6 of the supply unit 5, the conveyed product H enters the machine casing 1 from the supply port, and is conveyed toward the end along the bottom plate 2 by the moving conveyance body 16. Is done.
Conventionally, since a shutter is provided at the outlet of the discharge unit, it is necessary to provide a plurality of discharge units in order to distribute to a plurality of transport paths in the next process.

  In the present application, the machine casing 1 is configured so that the gap B between the left and right side plates 3 is conveyed while the bridge B is intentionally conveyed on the conveyance object H conveyed by the conveyance body 16 moving on the bottom plate 2. Since the transported object H in the lower layer part of the transported goods H is dropped from the dropping port 8 and the transported product H in the upper layer is allowed to pass through the dropping port 8 in a substantially bridge B state, the total amount of the transported material H at the start end of the dropping port 8 Since the transported object H is carried over toward the end of the drop port 8 without dropping, the start end and end of the drop port 8 formed to a predetermined length capable of providing the receiving ports 31 of the plurality of distribution rods 30 of the distribution unit 29 The difference in the amount of fall with the portion is suppressed, and the conveyed product H is dropped substantially uniformly from the start end portion to the end portion of the drop port 8.

That is, the transported object H in the state of the bridge B that has passed over the start end of the dropping port 8 is gradually collapsed by the bridge B that is intentionally generated by a stimulus such as vibration during transport to the lower side by the transport body 16. Then, it falls from the lower drop port 8, and all the transported goods H drop at the end portion of the drop port 8.
Accordingly, the substantially uniform transported object H falls from the start end portion to the end portion of the drop port 8 having a predetermined length sufficient to provide the plurality of receiving ports 31 of the distribution unit 29. In FIG. 5, the conveyed product H is distributed by each distribution basket 30, and is transported and processed in the subsequent steps.

In this case, the amount of fall at the start end of the drop port 8 and the amount of fall at the end need not be completely the same, and may be substantially equal as long as they do not affect the subsequent processes.
Since the distribution unit 29 has only to be provided with the respective distribution baskets 30 from the plurality of receiving ports 31 below the one discharge unit 10, it is easy to manufacture and assemble. The troublesome work of adjusting the shutter is also unnecessary.
Since the machine casing 1 is configured so that the layer thickness of the transported object H transported by the transport body 16 is a predetermined thickness, the bridge 1 is intentionally generated and transported above the start end of the drop port 8.
That is, if the layer thickness of the transported object H is thin, the gravity applied to the transported object H acts directly below and becomes easy to fall, but if the layer thickness becomes thicker than the predetermined thickness, the bridge is increased accordingly. B tends to occur.

For example, the machine casing 1 is set relatively to the left and right widths of the bottom plate 2 and the depth of the side plate 3 so that the layer thickness of the conveyed product H conveyed by the conveyance body 16 becomes a predetermined thickness. When the transport speed is set, the layer thickness of the transported object H transported in the machine casing 1 can be set to a predetermined thickness, and the bridge B can be intentionally generated in the transported object H being transported. The fall of the start end portion is suppressed, and the conveyed product H is dropped substantially uniformly from the start end portion to the end portion of the drop port 8.
In other words, the interval between the left and right side plates 3 is set so that the layer thickness, which is the thickness of the layer of the transported object H transported by the transporting body 16, takes into account the transport amount of the transported object H and becomes a certain level or more. The machine casing 1 and the transport body 16 are configured so that the bridge B is intentionally generated, and from the start end portion of the drop port 8 formed in a predetermined length that can be provided with the receiving ports 31 of the plurality of distribution rods 30 of the distribution unit 29. The conveyed product H is dispersed and dropped substantially evenly to the end portion.

Thus, since the opening width of the start end opening 35 at the start end of the drop opening 8 is narrower than the width of the left and right side plates 3 of the machine casing 1, the drop at the start end of the drop opening 8 is suppressed, and the drop opening 8 ensures the uniform fall of the conveyed product H from the start end to the end.
That is, not only the transported object H passing above the start-end opening 35 but also the transport object H is carried over the start-end receiving plate 34 on both sides of the start-end opening 35 to the lower side. 8 can suppress the difference between the amount of fall on the start side and the amount of fall on the end side, thereby improving the dispersion fall effect.
Further, by making the opening width of the start end side opening portion 35 narrower than the width of the left and right side plates 3, the bottom plates 2 on both sides of the start end side opening portion 35 become the start end side receiving plate portions 34. Moreover, the auxiliary | assistant effect | action through which the conveyed product H above the starting end side opening part 35 passes in the state of the bridge B is also anticipated.

The starting end opening 35 narrows the opening width of the starting end opening 35 in advance and secures a sufficient transport amount of the transported object H passing over the starting end opening 35, so that it terminates from the starting end of the drop port 8. A plurality of receiving ports 31 of the distribution unit 29 can be provided below the unit.
In this case, since the start end side opening 35 has a predetermined length in the transport direction and is formed to have substantially the same width from start to end, the length of the end portion from the start end of the drop port 8 can be increased. In addition, the number of receiving ports 31 of the distribution unit 29 can be increased.
In addition, since the opening width of the start end side opening 35 is narrowed in advance and the bottom plates 2 on both the left and right sides of the start end side opening 35 are formed in the start end side receiving plate 34, the conveyance on the start end side receiving plate 34 is performed. The object H is transported to the lower side, the amount of fall on the lower side of the drop port 8 is increased, and the difference between the amount of fall on the start side and the amount of fall on the end side of the drop port 8 is suppressed.

Thus, since the intermediate opening 38 wider than the opening width of the start end opening 35 is formed following the start end opening 35 at the start end of the drop opening 8, the intermediate opening 38 defines the start end opening 35. A part of the bottom plate 2 on both sides and a part of the bridge B which is intentionally formed are dropped.
Therefore, the difference between the amount of fall on the start end side of the drop port 8 and the amount of drop from the drop port 8 on the lower side than the start end side can be suppressed, and the dispersion drop effect is improved.
The intermediate opening 38 provided between the start end opening 35 and the end opening 36 has the same lateral width as the start end opening 35 at the start end of the intermediate opening 38, and the end of the intermediate opening 38. Is formed to have a slightly narrower left and right width than the end opening 36, and gradually increases in width from the start end to the end of the intermediate opening 38. The fall amount of the transported object H, which is gradually widened and is less transported than the start end portion of the drop port 8, can be made constant, and the fall amount at the start end portion of the drop port 8 and the intermediate portion of the drop port 8 The amount of fall is almost the same.

Since the lower end side opening 36 on the lower side of the intermediate opening 38 is opened over the same width as the left and right side plates 3, all the transported objects H transported to the end side opening 36 are dropped. The transported object H can be dispersed and dropped substantially evenly from the start end to the end of the drop port 8 having a predetermined length, and the remaining transported object H can be prevented.
Since the terminal side opening 36 on the terminal side of the dropping port 8 opens the full width at the bottom of the machine casing 1, the amount of the transported object H that is less transported than the starting end and the middle part of the dropping port 8. The amount of fall at the start and middle of the drop port 8 and the amount of fall at the end of the drop port 8 are made substantially the same.
That is, the length of the dropping port 8 is set to a length that does not cause overflow, but since the termination side opening 36 of the dropping port 8 is opened all over, the conveyance carried to the termination side opening 36 is performed. All of the objects H can be dropped at the terminal side opening 36 at the terminal end of the dropping port 8, and the residual transported object H in the machine casing 1 is not generated.

In this case, the length of the drop port 8 is set so as to open longer than the length of the transported object H falling due to the transport of the transporting body 16, so that the transported object H always falls at the terminal opening 36. .
In addition, each receiving port 31 of the distribution basket 30 is provided below the dropping port 8, but the length of the receiving port 31 at the end is different from the length of the other receiving ports 31, and the end of the receiving port 31 at the end is Since the terminal end opening 36 of the drop port 8 is matched with the terminal end 36, the remaining transported material H in the machine casing 1 is not generated even at this point.
Since a connecting portion 40 in the left-right direction for connecting the left and right bottom plates 2 is provided at a substantially intermediate position in the transport direction of the drop port 8, the bottom plate 2 and the side plates 3 on both the left and right sides of the intermediate opening 38 are connected to each other. 40 is connected to improve the rigidity of the machine casing 1 at the drop port 8 portion and suppress the twisting and distortion of the machine casing 1.

Since the pair of narrow left and right supports 41 are provided in the end opening 36, the support 41 supports the transport body 16 passing over the end opening 36 and prevents the transport body 16 from falling. .
In this case, since the support body 41 is arranged in a substantially “V” shape, the transport body 16 is in sliding contact with the entire surface of the support body 41, so that the transport object H does not remain on the support body 41.
In the embodiment of FIGS. 1 and 6, the length of the drop port 8 is set so as not to overflow, so that the transport body 16 is turned upward immediately after the drive sprocket 14, and the transport body 16 Does not necessarily slidably contact the entire surface of the support 41, but the conveyed product H does not remain on the support 41.
