Description

[Detailed description of the invention] Industrial field of application This invention is applicable to clothing transport and storage equipment in which a hanger is hung from the hook of a carrier running on a rail, and clothing is hung on the hanger during transport. This invention relates to a hanger product loading device that automatically hooks a hanger on which clothing or the like is hung, in a sorting device or the like in which the hanger is automatically unhooked and discharged to a desired unloading rail.

Prior Art In the conventional sorting device mentioned above, the part of the hook that projects laterally from the carrier with respect to the transfer direction is always inclined upward, and the hook is placed on an inclined chute facing the passageway at the tip of the hook. The hanger is transferred to the hook by sliding down the hanger at appropriate timing relative to the proximity of the hook. However, since the carrier speed changes depending on the load condition and the hanger sliding speed varies depending on the hanger load, the timing may be out of order and a hanger insertion error may occur.

Problems to be Solved by the Invention The purpose of the invention is to propose a hanger product loading device that mechanically connects a movable hook and a fixed inclined chute to prevent the hanger loading error.

Means for Solving the Problems In this invention, a hanger supplying inclined chute and a hanger supplying inclined chute are installed on the side of the transfer path of a conveyor in which a carrier running on a rail is provided with a hanger lifting hook projecting laterally with respect to the running direction. The proximal end is pivotally attached to the lower end of the chute, and the tip protrudes into the hook passage, and when engaged with the hook, it can swing around an axis perpendicular to the hanger sliding surface of the inclined chute, and the hanger can be slid down from the inclined chute and hooked. The present invention is characterized in that it is provided with a rocking chute capable of sliding down and down the conveyor, and that the rocking chute is normally biased to return to a position where it starts engaging with the hook in the upstream direction of the conveyor.

Action When the hook arrives and engages with the swinging chute,
The swinging chute swings against the biasing force due to the moving force of the hook, and the swinging chute and the hook maintain a mechanically connected state until the hook passes and the engagement is released. During this time, the hanger kept on standby on the inclined chute is slid down and transferred to the hook through the swinging chute. Since the mechanically connected state continues long enough until the glide of the hanger is completed, the hanger can be reliably placed on the hook even if the hanger glide speed varies or the conveyor speed fluctuates.

Example In the figure, a conveyor 1 is a circular tubular fixed rail 2.
A roller 4, which is pivotally supported on the upper part of the carrier 3, is mounted and runs, and a horizontal hook shaft 6 perpendicular to the transfer direction is rotatably supported on the lower protruding metal fitting 5 of the carrier 3.
A round bar-like hook 7 inclined so as to intersect with the hook shaft 6 is integrally formed at one end thereof. The proximal end of the hook 7 has a conical recess 8 formed in the protruding metal fitting 5.
It is stuck inside. The hook 7 is biased by a spring (not shown) to assume the upwardly tilted position shown in the drawing, and a cam 9 is fixed to the other end of the hook shaft 6 for inverting the hook 7 by 180 degrees and unloading the hanger. .

On the outside of the passage of the hook 7, the fixing member 10
A support plate 12 is attached to a vertical member 11 fixed to the vertical member 11 so as to be vertically adjustable. Fold the lower part of the support plate 12 along the line 1
3 is folded back into a U shape so as to be inclined downward at about 35 degrees toward the conveyor 1, and the rear lower surface of an inclined chute 15 made of a round bar is fixed to the folded end edge 14. Inclined chute 1
5 is in a plane substantially perpendicular to the transfer direction, the upper surface is inclined downward by about 35 degrees toward the passage at the tip of the hook 7, and the downwardly inclined end is located at the upper part of the outer side than the tip of the hook 7. do.

A planed surface 16 is formed in the lower half of the portion near the downwardly inclined end of the inclined chute 15, and a swinging chute 18 that slides in sliding contact with the planed surface 16 with a planed surface 17 is pivotally connected by a pin 19. The upper end of the pin 19 fits into a blind hole provided in the inclined chute 15 and is locked by the pin 20. The swinging chute 18 has an upper planed surface 17 at the base end in sliding contact with the planed surface 16, a lower planed surface 21 supported by the head of the pin 19 via a washer 22, and an inclined chute 15 of the upper surface 23 of the swinging chute. The upper half of the chute 15 has a cylindrical surface lower than the upper surface of the inclined chute 15, and the lower half has a conical surface 24, forming a hook-shaped recess 25 into which the hook 7 engages. The recess 25 allows the conical surface 24 to closely cover the tip of the hook that has entered, and while the swinging chute 18 swings in the transfer direction due to the moving force of the hook 7, the hook 7 is substantially close to the swinging chute 18. This makes it possible to abut within the vertical center plane.

Arm 2 attached to the inclined lower surface 26 of the support plate 12
A spring 28 is stretched between the folded end of the shaft 7 and the upper end of the swinging chute 18 to urge the swinging chute 18 so that its lower end swings to a fixed position on the upstream side of the conveyor 1.

An air cylinder 30 is fixed to an arm 29 protruding from the support plate 12, and its rod 31 is moved toward and away from the top surface of the tip of the inclined chute 15.

The hanger 32 has an upper end engaging portion 33 curved with an inner diameter sufficiently larger than the diameter of the inclined chute 15;
Inclined chute 1 by screw conveyor 34
5, the hanger 32 slides down on the inclined chute 15 and the rod 31 in the protruding state
stopped by. When a photoelectric switch or the like detects that the hook 7 approaches the swing chute 18, the air cylinder 30 shortens and the hanger 32
is released and slid down onto the swing chute 18. On the other hand, the hook 7 engages with the recess 25 of the swinging chute 18, and the hook 7 is engaged with the recess 25, and the hanger 32 is slid down from the swinging chute 18 to the hook 7 during this period. The hook 7 moves further and escapes from the recess 25, and the swing chute 18 returns to its original position by the spring 28 where it started engaging with the hook.

The air cylinder 35 is a temporary storage stopper for a hanger provided above the air cylinder 30,
When the number of hangers sent from the screw conveyor 34 is large, it is temporarily stored and sent to the air cylinder 3.
0 releases the hanger and then slides down the next hanger.

As the spring for returning the swing chute 18, a coil spring 28a may be used instead of the spring 28, which is wound around a pin 19 and has both ends locked to the pin and the swing chute 18, as shown in FIG.

Effects of the invention This invention has the above-mentioned configuration, and a swinging chute is provided between the fixed inclined chute and the movable hook, and is engaged with the hook so that it can follow and swing, so that the sliding speed of the hanger and the speed of the conveyor do not fluctuate. This has the effect that the hanger can be reliably inserted into the hook even when the hanger is placed in the hook.
