The rail unit 11 is arranged in upper and lower two rows along the longitudinal direction of the transfer line F to form a circulation rail.

The movable body 12 cyclically moves the rail 11 while moving forward in one direction along the rail 11. In the drawing, a chain-type movable body 12 connected to a caterpillar type is shown, but this not limited

The movable body 12 is guided by a plurality of vertical wheels and/or horizontal wheels while being constrained to the rail unit 11 to move in circulation, and the article loaded on the loading plate 32 of the tilting tray 30 . is transferred along the transfer line (F).

In addition, a plurality of discharge portions D inclined downwardly outwardly on one side or both sides of the rail portion 11 are provided with a predetermined interval apart in the longitudinal direction of the rail portion 11 to form a classification point.

The frame 20 has a lower end coupled to the movable body 12, and a first rotational shaft 33 of the tilting tray 30 is installed at an upper end in the front-rear direction, and the posture maintaining means ( 21) are combined.

In addition, the tilting block 31 includes a first elastic body 34 that elastically supports and presses the shaft 411, which will be described later, downward.

The first elastic body 34 is built in the shaft seol portion 311 of the tilting block 31, and the detailed configuration related to the posture maintaining means 21 and the first elastic body 34 is a locking member 40. will be described later with

And the tilting tray 30 is a box detective tilting block 31 coupled to the first rotation shaft 33 and rotatable left and right, and a loading plate 32 coupled to the upper surface of the tilting block 31. include

The tilting block 31 includes a shaft portion 311 protruding from the front portion of the frame 20, and the shaft 411 of the pressurized portion 41 to be described later is fitted to the shaft portion 311 left and right. It is coupled, and the second rotation shaft 43 of the locking member 40 is axially installed on the rear end side of the shaft 411 .

At this time, the shaft 411 is coupled through the shaft 411 on both sides of the shaft tongue portion 311, but is provided with a guide hole 312 formed to be inclined upwardly to the rear side.

Reference numeral 35 denotes a stopper having an inverted triangular shape coupled to the bottom surface of the tilting block 31, and limits the tilt angle when the tilting tray 30 is rotated left and right to a predetermined angle (approximately 30°).

The loading plate 32 has a shape in which the left and right ends are opened by forming sidewall portions bent upward at the front and rear ends, so that when the tilting tray 30 is tilted to the left or right, the article on the loading plate 32 is It falls to the left and right openings of the loading plate 32 to be discharged to the discharge part (D).

Subsequently, the locking member 40 allows the left and right rotation of the tilting tray 30 to be made and at the same time, the horizontal state of the tilting tray 30 is safely maintained through the posture maintaining means 21 .

Specifically, the locking member 40 is a member bent in a 'L' shape, and is pivoted back and forth by the second pivot shaft 43 coupled to the bent part, and rotates back and forth, and shears the bent part as a starting point. The pressurized portion 41 is coupled to the protrusion, and the binding plate 42 is coupled to the lower protrusion.

In addition, the pressurized portion 41 includes a shaft 411 coupled through the locking member 40 and a tilting roller 412 coupled to an end of the shaft 411 .

The shaft 411 penetrates through the front end protrusion of the locking member 40 and is fitted and coupled to the guide hole 312 , and is tilted at the end of the shaft 411 exposed on both sides of the guide hole 312 . The roller 412 is rotatably coupled back and forth.

At this time, the shaft 411 is elastically supported to be pressed downward by the first elastic body 34. As long as external pressure is not applied to the locking member 40, the first elastic body 34 is elastically supported by the elastic force of the first elastic body 34. The locking member 40 is forced to rotate downward.

In addition, the binding plate 42 includes a locking groove 421 formed on the rear surface,

The posture maintaining means 21 includes a locking rod 211 coupled to the front of the frame 20 so as to be retractable and retractable, and a second elastic body 212 for elastically supporting the locking rod 211 forward.

As the first elastic body 34 and the second elastic body 212 , a compression spring that exerts an elastic force in a direction opposite to the compression is typically used, but is not limited thereto.

The front end of the locking rod 211 and the locking groove 421 have a hemispherical shape corresponding to each other.

The locking rod 211 is elastically supported forward by the second elastic body 212 while being embedded in the housing 213 coupled to the inner surface of the front part of the frame 20 by a long bolt 214, The front end of the rod 211 can be drawn in and out through a protrusion hole (not shown) provided in the front portion of the frame 20 .

When explaining the organic operation of the posture maintaining means 21, the first elastic body 34 and the locking member 40,

First, as the shaft 411 is pressed downward by the first elastic body 34 in a state in which the tilting tray 30 is horizontally maintained, the locking member 40 is always rotated downward.

Accordingly, as the binding plate 42 is in close contact with the front portion of the frame 20 , the locking rod 211 is inserted into the locking groove 421 of the binding plate 42 , and the tilting frame 20 is horizontally state is maintained

And when external pressure is applied to one of the left and right tilting rollers 412 of the locking member 41 so that the shaft 411 receives a rising pressure, the shaft 411 is guided along the inclination of the guide hole 312 and rises. will do,

Accordingly, as the front end protrusion of the locking member 40 is lifted and the locking member 40 is rotated upward, the binding plate 42 is spaced apart from the front portion of the frame 20, in the locking groove 421 The locking rod 211 is released and the lock is released, so that the tilting tray 30 can be rotated left and right.

Subsequently, the tilting guide 50 is provided on the rear end side of the discharge part D. In the drawings of the present specification, the tilting guide 50 is installed to be inclined upwardly inward, and a cylinder is used as the driving part 51 . Although the illustrated embodiment is representatively shown, it is not limited thereto (for example, it is also possible to rotate the tilting guide installed in the vertical direction to be inclined inwardly).

The tilting induction part 52 has an inclined surface 521 inclined upward toward the forward direction of the movable body 12, and when the tilting induction part 52 is raised by the height variable driving part 51, the tilting roller 412 ), as the tilting roller 412 moves along the inclined surface 521 of the tilting guide part 52, the locking member 40 and the tilting tray 30 are rotated. let it go

At this time, the tilting guide 50 is installed to be inclined upwardly toward the inside in which the rail part 11 is provided.

The reason for installing the tilting guide 50 to be inclined is that the tilting guide part 52 of the other tilting guide 50 provided on the other side is drawn out and rises while the tilting tray 30 is tilted to one side while being transported. This is to prevent the tilting tray 30 from colliding when a malfunction occurs.

That is, when the tilting tray 30 is in contact with the tilting guide part 52 on one side of the front end and the product is discharged and then continues to move, it passes through the discharge part D and is installed elsewhere among the tilting guides 50. The tilting guide unit 52 on the other side may operate upward due to malfunction. ), etc. may occur, so even if the tilting guide 50 malfunctions by installing the tilting guide 50 itself to be tilted at a predetermined angle, the tilting guide part 52 operates the tilting block 31 and the loading plate 32. Prevent collisions by placing them in the lower space between them.

At this time, the installation angle of the tilting guide 50 varies depending on the specification (standard) of the tilting tray 30 , such as the size of the tilting block 31 and the tilt angle of the tilting tray 30 .

When describing the article sorting operation of the present invention including this configuration,

First, the goods to be sorted are transferred and loaded on the loading plate 32 of each tilting tray 30 moving along the rail part 11 .

At this time, as described above, since the locking member 40 is locked by the posture maintaining means 21 , the left and right rotation of the tilting tray 30 is impossible, and thus the weight of the article placed on the loading plate 32 or Regardless of the position, etc., the horizontal state of the loading plate 32 is always maintained so that the goods are safely transported.

And just before reaching the sorting point (position) of the article while the tilting tray 30 moves forward, one of the left and right tilting guides 50 of the corresponding discharge unit D lifts up.

Referring to FIG. 2 , as the right tilting guide part 52 rises, it is positioned on the moving path of the right tilting roller 412 .

And when the tilting tray 30 enters the corresponding discharge part D, the right tilting roller 412 comes into contact with the tilting guide part 52 of the right tilting guide 50 to ride the inclined surface 521 and tilt while moving upward. The induction part 52 is passed.

Accordingly, the shaft 411 rises along the guide hole 312 while compressing the first elastic body 34, and the locking member 40 upwardly rotates at a predetermined angle (approximately 6°), the posture maintaining means (21) is unlocked.

After unlocking the locking member 40 , if the right tilting roller 412 continues to ride on the inclined surface 521 , the upward pressure applied to the shaft 411 is on the right side of the tilting block 31 . As it is applied, when the tilting tray 30 passes the discharge part D, it is inclined at a predetermined angle (about 30°) to the left with respect to the first rotation shaft 33 .

As the tilting tray 30 is tilted in this way, the articles on the loading plate 32 fall to the left discharge part D to be separated and discharged, and the empty tilting tray 30 continues to move forward as the articles are discharged.

At this time, when the right tilting roller 412 deviates from the inclined surface 521 of the right tilting guide 50, the shaft 411 moves to the lower end of the guide hole 312 by the elastic force of the first elastic body 34. As it descends, the locking member 40 rotates to its original angle and returns.

And the tilting tray 30, on which the separation and discharge of the goods is completed, passes the front end of the rail 11 in a tilted state, and is installed according to the rising height of the tilting roller 412. As the right tilting roller 412 is pressed downward, the tilting tray 30 rotates to the right.

In this way, when the tilting tray 30 is tilted back to the right and returned to rotate, the binding plate 42 is in close contact with the front part of the frame 20, and the side end of the binding plate 42 is Push the front end of the locking rod 211 to the rear to retract,

When the tilting tray 30 is in a horizontal state, the locking rod 211 protrudes toward the front portion of the frame 20 while advancing again, and is inserted into the locking groove 421 of the binding plate 42 to be locked. Accordingly, the tilting tray 30 is stopped while the horizontal state is maintained, and the transfer cart M is circulated while continuing to move along the rail part 11, so that the sorting operation of the article is continuously performed.

Therefore, the present invention does not use a separate electric part for the left and right rotation of the tilting tray 30, so that the classification accuracy of items is always maintained, and the horizontal state of the tilting tray 30 is safely maintained before passing the sorting point. Therefore, the transport of goods is carried out safely regardless of the weight or location of the goods.

On the other hand, in the housing 213, the long bolt 214 passes through the through hole 213a of the housing 213 and is screwed to the front portion of the frame 20 to be mounted. The long bolt 214 cannot be fixed by tightening it with a nut.
