Description

The present invention relates to a lateral discharging chute attached to a transfer device, and more particularly to a chute suitable for laterally discharging a transfer object by tilting a tray during movement of a sorter.

FIG. 1 shows a state in which a transported object slides down when a sorter is combined with a conventional chute. That is, the transfer material M discharged from the tray 2 of the sorter 1 onto the chute 3 has a sorter speed x
And the chute sliding frictional force is added to the combined velocity of the vertical descent velocity y on the chute 3 and generally descends along a parabolic curve with unspecified rotation. Therefore, conventionally, the chute inlet width A is set to be sufficiently large so that the transferred object M does not collide with the upright chute side wall 3a and is damaged, and the transferred object M causes jamming due to an unspecified rotation posture. To avoid this, the chute outlet width B needs to be set larger than the length of the diagonal line of the transferred material M, and from these points, the number of chutes, and thus the number of sorting is limited.

In order to solve the above-mentioned problems of the prior art, the present invention aims to increase the number of sorting chutes installed per unit transfer length of the sorter by reducing the entrance width of the chute. A bottom surface (5) that slides and guides a chute attached to a transfer device that moves in the longitudinal direction as the transport direction and discharges the transport object to the side in the transport direction;
Immediately after being discharged from the transfer device, the transfer direction is close to the front end position of the transfer object and through the curved surface (10) that gradually guides the longitudinal direction of the transfer object in the downhill direction from the front end portion of the bottom surface in the transfer direction. Front side wall (6) rising perpendicular to
And a rear side wall (7) having a distance to the front side wall (6) that becomes smaller as it goes down behind the bottom surface in the transport direction, and a bottom surface (5) from the inner surface of the rear side wall (7).
Of the transferred article rear outer end immediately after the discharge from the chute inlet (the upper end of the line of intersection (bd) with the bottom surface (5) passes through the bottom end of the chute inlet). k) and a first slope (11) that guides the front end of the transported object to rotate in a sliding direction, and a first slope (11) that is connected to the slope (11) and is substantially below the bottom surface (5) from the inner surface of the rear side wall (7). A second slope (12) which is inclined downwards toward the half and whose intersection line (ab) with the bottom surface (5) passes through the lower end of the intersection line (bd) and is substantially parallel to the front side wall (6). And, at the lower end of the line of intersection (bd) of the first slope (11), the longitudinal direction of the transferred material is rotationally guided to the chute exit direction, and the line of intersection of the second slope (12) ( According to ab), the side discharge chute regulates the excessive turning of the transferred material.

An embodiment of the present invention will be described below with reference to FIG.

In the present embodiment, the chute 4 discharges the transfer material M to the side perpendicular to the transfer direction of the sorter 1, the bottom surface 5 inclined to the side, the front side wall 6 perpendicular to the transfer direction, and the front side as it descends. It has a rear side wall 7 having a small distance from the side wall 6, and has a wide inlet 8 and a narrow outlet 9 in the transfer direction. However, the front side wall 6 is close to the front end position of the transferred object immediately after being discharged from the sorter through the conical surface having a small diameter from the inlet 8 to the outlet 9 or a curved surface 10 close to the conical surface and being in contact with the curved surface 10. The first rising from the bottom surface 5 and tilting downward from the inner surface of the rear side wall 7 toward almost the upper half of the bottom surface 5.
And a second slope 12 that inclines downward from the inner surface of the rear side wall 7 toward substantially the lower half of the bottom surface 5. Slope 1
An intersection line ab between the 2 and the bottom surface 5 is substantially parallel to the front side wall 6, and an intersection line bd between the slope 11 and the bottom surface 5 has an upper end passing through the rear end of the inlet 8 and a lower end passing the upper end b of the intersection line ab. Slopes 11 and 12
Intersect with the ridge line bc.

The transferred material on the tray 2 which is transferred with the longitudinal direction as the transport direction is discharged sideways in its posture, that is, with the longitudinal direction of the transferred material parallel to the transport direction, and the bottom surface 5 of the chute 4 is discharged. Downhill on the rear outer edge k in position
The point slightly rides on the slope 11 and the frictional force with the chute 4 locally increases. Therefore, the transferred material M descends while rotating and guiding the longitudinal direction of the transferred material around the point k toward the exit of the chute 4 (position), and the transferred material bottom side k descends from the position to the position substantially parallel to the intersection line bd. Then, the inner end m of the front portion of the transferred object rides on the curved surface 10 and the longitudinal direction of the transferred object is guided to deflect in the downhill direction without impact. At this time, point m is b
Below the point, due to the downward blocking force at the point b and the contact pressure applied from the curved surface 10 to the point m by the downward force of the transported material M, the transported material M is rotated around the point b and the length of the transported material is increased. The direction is changed to the exit direction of the chute, and the posture is changed from the position to the position perpendicular to the transfer direction by the rotational inertia, and the chute is discharged from the exit 9. The inclined surface 12 gently prevents the transferred material M from excessively rotating, and, together with the rotation promoting action of the curved surface 10, guides the transferred material M from the outlet 9 in a desired posture.

If the transfer material M is to be delivered obliquely forward from the outlet 9 as shown by the chain line, the front side wall 6 and the intersection line ab may be oriented in the delivery direction.

According to the present invention, the transported object is transported with the longitudinal direction of the transported object being slid down and discharged sideways, and immediately after sliding down from the chute entrance, the rear end of the transported object is guided by abutting the first slope to the front end of the transported object. While being forced to rotate in the downhill direction,
The inner end of the front part of the transferred object rides on the curved surface interposed between the bottom surface of the chute and the front side wall to guide the longitudinal direction of the transferred object in the downhill direction without impact, thereby deflecting the longitudinal direction of the transferred object in the downhill direction. As a result, it is possible to prevent the transferred material from colliding with the front side wall of the chute, so that the entrance width of the chute can be made narrower than before, and the transferred material slides down due to its own weight at the lower end of the first slope. And the longitudinal direction of the transferred product is guided toward the chute outlet direction, and the second inclined surface restricts excessive rotation of the transferred product, so that the longitudinal direction of the transferred product is along the discharge direction of the chute outlet. Since it slides down on the bottom of the chute in a vertical posture, it is possible to make the chute exit width narrower than the longitudinal length of the transferred product, and as a result, the chute entrance width and exit width can be reduced. Significantly reduced than before,
The number of chutes installed in parallel can be greatly increased,
The sorting efficiency has been dramatically improved, and the delivery postures of the transported items are aligned, which is convenient for automating various readings and removals of the transported items after the delivery. It has the effect of being small.
