DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of rods having a constant thickness, which are accommodated in a substantially parallel arrangement.
The present invention relates to a hopper for a rod-like body which is taken out one by one.

[0002]

2. Description of the Related Art In a manufacturing process of a rod-shaped body, for example, a rubber roller for feeding paper of a copying machine, a pair of left and right parallel grooved rails is used as a supply device for feeding the rubber roller one by one to a grinder or other processing machine. A groove is provided so as to be inclined with respect to the horizontal plane so that the grooves are opposed to each other, and the left and right groove guides rotatably support the ends of a large number of rubber rollers, and the lower end of the groove guide receives the rubber rollers at the lower end. A pair of left and right feed discs having an outer periphery are provided, and the feed discs are reciprocated by a predetermined angle to take out rubber rollers one by one from the lower end of the grooved guide and send them to a lower polishing machine or other roller processing section. Such is known.
However, in this device, the number of rubber rollers that can be accommodated in the grooved guide is small, and manual operation is required to accommodate the rubber roller in the grooved guide. In addition, the grooved rails can be formed in a zigzag shape to increase the number of rubber rollers to be accommodated. However, in this case, the rubber rollers roll poorly at the corners, and roller clogging easily occurs.

[0003] Further, a large number of pairs of left and right V blocks are connected at equal intervals to form an endless conveyor.
Rubber rollers are placed one by one on the block and transported horizontally,
At the end, a rubber roller is gripped and lifted from the V block by a chuck, and then the chuck is moved forward, and then the chuck is lowered and transferred to a chuck of a processing machine such as a polishing machine. However, in this case as well, it is necessary to increase the installation area in order to lengthen the conveyor, so that the number of rubber rollers to be accommodated is limited and limited, and manual work is required to mount the rubber rollers on the V block.

[0004]

According to the present invention, a plurality of rods having a circular cross section, such as a rubber roller, a metal core thereof, and a rubber roller to which the metal core is attached, are put into a container in substantially parallel widths. For example, the above-mentioned rod-shaped bodies can be automatically taken out one by one from one end of the bottom portion thereof and supplied to the rubber roller polishing machine and other processing machines, the upper ends of the pair of left and right grooved rails, the V block of the conveyor, and the like. A hopper for a rod-shaped body is provided.

[0005]

According to the present invention, there is provided a hopper for a rod-like body, in which a plurality of rod-like bodies having a circular cross section are arranged in parallel and mounted.
A gutter-shaped container is formed by fixing side plates to the left and right sides of the bottom plate inclined forward and downward so that it can roll by its own weight, and a slide plate that intermittently reciprocates in the front-rear direction along the upper surface of the bottom plate is provided. Above the front end of the bottom plate, a columnar adjusting roller is provided horizontally at an interval that allows one of the rods to pass therethrough so that the lower surface thereof rotates in a direction in which the lower surface moves backward. It is characterized in that a pair of left and right feed discs are provided on the outer periphery, which are provided with recesses into which rods can be fitted, and which can intermittently reciprocate a predetermined angle and take out the rods one by one from the lower end of the bottom plate. And

The above-mentioned rod-shaped body may be any one that can be handled as a rod-shaped body having a substantially constant outer diameter, and more specifically, one that rolls almost straight when placed on an inclined surface. Cylindrical or columnar bodies with a smooth surface and a constant outer diameter, such as gold, those with a small diameter part that is partially short, such as a rubber roller with the above-mentioned cored bar, and those with cloth-like irregularities on the surface, etc. Either may be used.

[0007] In the above-mentioned hopper for rod-like bodies, when a number of rod-like bodies are aligned substantially in parallel and put into a gutter-shaped container,
Since the slide plate reciprocates intermittently in the front-rear direction, the rod-shaped body in the gutter-shaped container is swung in parallel with the bottom plate. On the other hand, since the lower surface of the adjustment roller rotates in a direction in which the lower surface moves rearward, the rod-shaped body in contact with the adjustment roller is pushed back and then falls forward. Therefore, even if the rod forms a bridge between the slide plate on the bottom plate and the adjustment roller, this bridge is broken by the movement of the slide plate and the adjustment roller, and one bridge is formed between the front end of the bottom plate and the lower surface of the adjustment roller. Of the bottom plate enters in a posture parallel to the front edge of the bottom plate and the adjusting roller, which falls from the front edge of the bottom plate and is accommodated in the concave portion of the feed disc, and is taken out with the rotation of the feed disc. . Then, when the feed disk is returned to its original position, the next bar is dropped and accommodated in the recess, and the bar is taken out in the following manner.
Books can be continued smoothly.

The distance between the front end of the bottom plate of the trough-shaped container and the lower surface of the adjusting roller can be formed so as to be adjustable in accordance with the thickness of the rod. In this case, the distance can be finely adjusted by changing the inclination angle of the bottom plate. Further, the interval between the left and right side plates of the gutter-shaped container can be formed so as to be adjustable in accordance with the length of the rod-shaped body. In addition, a plurality of gutter-shaped containers are arranged side by side, and one
A plurality of adjusting rollers can be attached to the plurality of trough-shaped containers, and rods having the same size or different sizes can be put into each of the plurality of gutter-shaped containers. In addition, the movement timing of the slide plate and the adjusting roller is such that the feed disc positioned below the adjusting roller stops its concave portion toward the gap between the front end of the bottom plate of the gutter-shaped container and the lower surface of the adjusting roller. It is preferable that after the rod falls, the slide plate reciprocates back and forth, and at the same time, the adjusting roller rotates by a predetermined angle. The rotation of the adjustment roller may be continuous rotation, but intermittent rotation is preferable in consideration of wear.

Although the sliding distance of the slide plate depends on the diameter of the rod, it is preferably 20 to 30 mm for a paper feed roller having a diameter of 5 to 35 mm for a copying machine, and the diameter of the rod is 35 to 35 mm. The slide distance in the case of 60 mm is 35 to 5
0 mm is preferable, and if the sliding distance is too short, there is no effect of sliding. The diameter of the adjusting roller is preferably increased as the diameter of the rod increases. For example, when the diameter of the rod is 5 to 35 mm, the circumferential length of the adjusting roller is 150 mm.
about 1-2 mm, and rotate it one or two times.
In the case of 60 mm, the circumferential length of the adjustment roller is about 280 mm and
It is preferable to make two to two rotations. If the amount of rotation is too small, there is no effect of rotating, and if it is too large, excessive rotation will occur and wear of the adjusting roller will increase.
