Explaining one embodiment of the present invention with reference to the drawings, reference numeral 1 denotes a case of a lateral feed transport device H, which is formed long in the transport direction. A supply unit 2 is provided at an upper position on one end side (start end side) of the case 1, and a discharge unit 6 having a drop opening 5 is provided on the other end side (end end side) (FIG. 1).
In this case, one or a plurality of discharge portions 6 may be provided in the intermediate portion of the case 1 in the transport direction, and the intermediate discharge portion 6 is provided with a shutter 7 for opening and closing the drop opening 5.
A conveyor 10 is provided in the case 1. For convenience of explanation, the upper side of the conveyor 10 in the transport direction is referred to as "front" and the lower side is referred to as "rear".
The drive gear 13 of the conveyor 10 is pivotally mounted by the drive shaft 14 in the case 1 on the front side of the discharge unit 6 which is the most terminal of the discharge unit 6, and a plurality of conveyors are mounted between the driven roller 11 and the drive gear 13. An endless chain 16 provided with 15 at predetermined intervals is hung around (FIG. 1).

The supply unit 2 is provided on the rearmost side of the case 1 and on the rear side of the driven roller 11.
Therefore, the length of the case 1 can be shortened with respect to the distance that the conveyor 10 conveys the conveyed object from the supply unit 2 to the discharge unit 6.
That is, in the conventional lateral feed transport device H, the supply unit 2 is provided on the front side of the driven roller 11 to prevent the driven roller 11 from biting the conveyed object, and the supply unit 2 and the discharge unit 6 are prevented by that amount. The total length of the lateral feed transport device H becomes longer with respect to the transport distance between them, and the device becomes larger.
In the present invention, the supply unit 2 is provided on the rear side (front side) of the driven roller 11, and the biting prevention body 18 for preventing the driven roller 11 from biting the conveyed object is provided.

Therefore, the biting prevention body 18 prevents the driven roller 11 from biting the transported object, and the supply unit 2 is provided on the rear side (front side) of the driven roller 11 to provide the total length of the lateral feed transport device H with respect to the transport distance. Can be shortened.
The supply port 20 is opened in the rear plate 19 of the case 1, and the supply chute 21 of the supply unit 2 faces the supply port 20 (FIG. 2). The supply chute 21 is provided with a bottom plate 23 inclined forward downward on the left and right side plates 22, and the bottom plate 23 is fixed to a vertical plate-shaped mounting plate 24. Reference numeral 25 denotes a supply opening of the supply chute 21, and a base portion 26 constituting a part of the supply portion 2 is detachably attached to the supply opening 25.

An arbitrary transport means 27 or the like such as an elevator is connected to the base portion 26 of the supply unit 2 (FIG. 1).
A derivative 29 is provided below the rear side of the driven roller 11 in the case 1, the derivative 29 is formed at substantially the same inclination angle as the bottom plate 23 of the supply chute 21, and the rear side of the derivative 29 is connected to the lower end of the supply port 20. , The front end of the derivative 29 is brought into contact with the bottom plate 30 of the case 1 (FIG. 2).
The bite prevention body 18 is located at the left and right intermediate positions of the supply port 20, and is formed in a V shape that becomes wider toward the rear side in a plan view, and the conveyed material supplied from the supply unit 2 is on the left and right sides of the driven roller 11. And prevent the conveyed object from being caught by the driven roller 11.
Therefore, in the bite prevention body 18, the upper portions of the left and right vertical plates 31 are fixed to the mounting plate 32, and the mounting plate 32 is detachably attached to the upper cover 33 at the starting end of the case 1.
In a plan view, the left and right ends of the pair of vertical plates 31 of the bite prevention body 18 are positioned inside the left and right side plates 34 of the case 1 by a predetermined interval, and the left and right end edges of the bite prevention body 18 and the side plates 34 of the case 1 are positioned. A conveyed material flow path 35 is formed between the two (FIG. 4).

Therefore, the conveyed material supplied to the supply unit 2 is guided to both the left and right sides of the driven roller 11 when entering the case 1 from the supply port 20, and the biting of the conveyed material by the driven roller 11 is suppressed.
That is, in a plan view, the left-right width of the bite-preventing body 18 is arbitrary, but it may be at least wider than the left-right width of the driven roller 11. The left and right widths are substantially the same, and both the prevention of biting of the driven roller 11 and the securing of the supply amount of the transported material are achieved.
In other words, since the conveyed object is bitten into the portion where the conveyed chain 16 meshes with the driven roller 11, it is sufficient if the inflow of the conveyed object to the left and right sides of the driven roller 11 can be suppressed. It should be at least wider than the left and right width of the driven roller 11.
Further, a predetermined gap 36 is provided between the lower end of the bite prevention body 18 and the upper surface of the derivative 29 (FIG. 3).

Therefore, when the supply amount to the supply unit 2 is reduced at the final stage of the transfer work by the lateral feed transfer device H, it is possible to prevent the conveyed object from remaining on the front side of the bite prevention body 18.
As a result, the inclination angle between the bottom plate 23 of the supply chute 21 and the derivative 29 is set to be steeper than the angle of repose of the conveyed object, thereby preventing the conveyed object from remaining.
Further, the rotation locus of the carrier 15 by the driven roller 11 is brought as close as possible to the front end of the bite prevention body 18 in a plan view.
Therefore, the total length of the lateral feed transport device H is shortened.
An air blower pipe 38 is provided between the bite prevention body 18 and the driven roller 11. The air blower pipe 38 is in the left-right direction and is attached to the upper cover 33 of the case 1. The air blower pipe 38 blows downward to prevent the driven roller 11 from getting caught and the derivative 29 from remaining.
A plurality of air outlets are arranged side by side in the air air duct 38 in the left-right direction, and one end of the air air duct 38 projects upward from the upper cover 33 to connect the air nozzle 39.

In FIG. 2, reference numeral 97 denotes a side supply port provided on the side plate 34 of the case 1, and when it is possible to supply the transported material from the side due to restrictions on the installation location, the supply unit 2 is provided to the side supply port 97. The supply chute 21 is provided.
Reference numeral 98 is a reflector, which prevents the conveyed material supplied from the side supply port 97 from flowing to the driven roller 11 side, and improves the versatility of the lateral feed transfer device H in combination with the side supply port 97. I'm letting you.
Further, in the case 1, the upper part of the conveyor 10 other than the upper cover 33 is blocked by the top plate 33A (FIG. 1).
The shutter 7 is configured to be moved parallel to the transport direction with respect to the case 1 to open and close.
Therefore, the operating space of the shutter 7 can be accommodated within the left-right width of the lateral feed transport device H, and the left-right width of the lateral feed transport device H is reduced.

Since the shutter 7 of the conventional lateral feed transport device H is slid in the crossing direction with respect to the transport direction to open and close the drop opening 5 of the discharge unit 6, the opened shutter 7 projects to the side of the case 1, so that the shutter is shuttered. The working space of 7 is projected to the outer side from the case 1 of the lateral feed transport device H, and the left-right width of the lateral feed transport device H is increased by that amount.
As shown in FIG. 6, the shutter 7 is formed in a flat plate shape, and the base portion of the shutter 7 is fixedly attached to the rotation shaft 40 in the left-right direction. The rotating shaft 40 is rotatably mounted on the side plate 42 of the shutter frame 41. An opening / closing actuator (air cylinder) 44 is attached to the rotating shaft 40 protruding from the side plate 42 of the shutter frame 41 via a link mechanism 43, and the opening / closing 5 of the discharge portion 6 is opened / closed by the expansion / contraction of the rod 45 of the opening / closing actuator 44. ..
The shutter frame 41 has a horizontal upper plate 47 fixed to the upper end of the side plate 42, an opening 48 located below the drop opening 5 of the discharge portion 6 is provided in the upper plate 47, and when the shutter 7 is rotated upward, the opening is opened. When the portion 48 and the opening 5 are closed and the shutter 7 is rotated downward, the opening 5 and the opening 48 are opened.

In this case, the opening area of the drop opening 5 is formed to be smaller than the opening area of the opening 48, and the plate thickness of the shutter 7 is the same as or thicker than the plate thickness of the bottom plate 30 of the case 1 and the upper plate 47 of the shutter frame 41. When the shutter 7 is formed into the fitting portion 49 that fits the shutter 7 into the drop opening 5 and the contact portion 50 that abuts on the lower surface of the bottom plate 30 of the case 1, the contact portion 50 of the shutter 7 becomes the bottom plate 30 of the case 1. It is possible to contact the surface and close the drop opening 5 of the supply unit 2 almost completely (FIG. 9).
Then, the shutter 7 is fixedly attached to the rotating shaft 40 via the pair of left and right stays 51.
Therefore, even if the shutter 7 rotates in an arc around the center of the rotation shaft 40, the fitting portion 49 of the shutter 7 fits smoothly and surely into the drop opening 5 of the case 1.
The configuration of the link mechanism 43 is arbitrary, but as an example, the intermediate portion of the first arm 53 is fixed to the rotating shaft 40, and the tip of the second arm 54 is rotatable at one end of the first arm 53. The base of the second arm 54 is rotatably attached to the rod 45 of the opening / closing actuator 44.

The base of the opening / closing actuator 44 is attached to the shutter frame 41 by the stay 55.
The other end of the first arm 53 sandwiching the rotation shaft 40 is formed on an open / close display unit 57 that displays the open / closed state of the shutter, and the open / close display unit 57 indicates the closed state of the shutter 7 in the horizontal state. Rotates downward to the center of the rotation shaft 40 to open the drop opening 5, and the open / close display unit 57 rotates diagonally downward with the shutter 7 to the center of the rotation shaft 40 to indicate that the shutter 7 is in the open state. (Fig. 8).
Therefore, the opening / closing of the shutter 7 can be mechanically displayed without using a special operating mechanism by using a part of the link mechanism 43, and the entire lateral feed transport device H can be provided at low cost.
The first arm 53 and the second arm 54 of the link mechanism 43 are arranged within the left-right width of the opening / closing actuator 44 arranged on the side of the side plate 34 of the case 1 in the front view.

Therefore, the left-right width of the lateral feed transport device H can be further reduced, and the movement of the worker in the facility in which the lateral feed transport device H is installed can be facilitated, and the maintenance of the facility can be facilitated. can.
An air blower pipe 38 is provided above the drop opening 5 of the discharge portion 6. The air blower pipe 38 is in the left-right direction, and although not shown, it is attached to the upper cover 33 of the case 1. The air duct 38 blows downward and drops the transported object on the transport chain 16 passing through the drop opening 5.
Then, in the case 1, a lower side plate 60 that stands up substantially vertically is provided on the left and right sides of the case bottom plate 30 to form a grain flow path 61 (FIG. 5), and as it goes above the upper end of the lower side plate 60. An inclined support plate portion 62 provided so as to spread laterally is formed, while each of the conveyed bodies 15 is constantly in sliding contact with the upper surface of the left and right inclined support plate portions 62 by a vertical plate member of synthetic resin. It is configured to have a central central portion 64 of the left and right inclined sliding contact surfaces 63 and the left and right inclined sliding contact surfaces 63, and the lower edge of the central portion 64 of the carrier 15 is smaller than the grain between the bottom plate 30 and the bottom plate 30. It is configured to move with a gap (0 to 1 mm).

If the inclined support plate portion 62 is provided in the lower part of the case 1 in this way, the cross-sectional shape of the case 1 becomes complicated, but the transport body 15 is moved in a supported state, and the transportable material can be reliably transported. ..
Further, when the drop opening 5 of the discharge portion 6 is provided at an intermediate position between the start end portion and the end portion of the transport path, the transport body 15 is below the drop opening 5 without providing a special support mechanism in the discharge portion 6. Can be moved without falling to.
A mounting portion 64A is provided at an intermediate position between the left and right sides of the transport body 15, and an endless chain 16 is mounted on the mounting portion 64A (FIG. 5).

The left and right sides of the detection shaft 68 are rotatably attached to the side plates 34 of the case 1. The base of the slack display body 69 is fixedly attached to either the left or right end of the detection shaft 68. The slack display body 69 is formed in a vertical plate shape and an arm shape, and the slack display body 69 rotates up and down around the center of the detection shaft 68 due to the rotation of the detection shaft 68.
A display unit 70 is provided at the tip of the slack display body 69, and when the slack detection roller 66 is lowered due to the slackening of the upper endless chain 16, the slack display body 69 is displayed at the center of the detection shaft 68 by the rotation of the detection shaft 68. The upper endless chain 16 is displayed to be loosened by moving (rotating upward) the portion 70 from a predetermined position.

In this case, the display method of the display unit 70 is arbitrary, but since the display unit 70 moves upward to the center of the detection shaft 68 due to the downward rotation of the slack detection roller 66, the slack detection device 65 is provided in the present embodiment. The normal display unit 70 is concealed from the cover 71, and the display unit 70 moves upward from the cover 71 to be exposed and displayed so that the presence of the cover 71 can be visually recognized (FIG. 12). ).
It should be noted that the setting of the lowering amount of the slack detection roller 66 due to the slack of the upper endless chain 16 is arbitrary. It may be set based on an arbitrary detection result such as comparing and setting the detection value of the tension and the slack amount of the upper endless chain 16 when the transport amount of the transport body 15 is less than the allowable transport amount.
Further, in the side view, when the slack detection roller 66 is arranged on the rear side, the display unit 70 is arranged on the front side, and the detection shaft 68 is arranged between the slack detection roller 66 and the display unit 70, the lowering of the slack detection roller 66 is displayed on the display unit 70. It is easier to display and has a rational structure.

Further, a plurality of weight bodies 74 can be detachably attached to the front end side of the arm 67.
Therefore, by changing the number of weights 74, the supporting load that supports the upper endless chain 16 of the slack detecting roller 66 can be changed, and the detection sensitivity of the slack detecting device 65 can be changed.
Further, a slack protrusion 75 indicating slack by the slack detection roller 66 is provided at a predetermined position on the front side of the arm 67 separately from the display unit 70, and the height position of the slack protrusion 75 is electrically detected at the predetermined position of the cover 71.

It may be controlled.
The slack display body 69 is provided with an arc-shaped regulation groove 88A at the center of the detection shaft 68, and the regulation protrusion 88B provided on the case 1 side is inserted into the regulation groove 88A.

It suffices if the slack detection roller 66 rotates downward to detect slack, and if the slack detection roller 66 descends excessively, problems such as contact with the carrier 15 occur. Prevent by contacting.
