Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic stick aligning machine for supplying a bar-shaped bar (hereinafter referred to as a stick) to an automatic machine.

[0002]

2. Description of the Related Art Conventionally, when a stick having a rectangular cross section, for example, is supplied to an automatic machine for performing various processes on a stick, an alignment operation for individually feeding the sticks to the automatic machine is required. Conventionally, this operation is performed manually, and the sticks 1 stacked in a row are arranged in a line as shown in the sketch in FIG. 4B, as shown in the sketch in FIG. 4A. They were aligned like stick 2.

[0003]

Since the conventional stick alignment relies on manual operation, there has been a problem that production equipment that requires stick alignment cannot be fully automated.

Another problem is that the loading of the operator is large.

[0005]

According to the present invention, there is provided an automatic stick aligning machine comprising: an inclined rail for allowing a stick to slide down by its own weight; a lower cam having a head slightly protruding from the rail surface; Provide a pair of upper cams,
The upper cam is installed above the rail at a fixed distance from the lower cam surface, and the upper and lower cams each have a plurality of protruding arc-shaped portions and have a structure that rotates synchronously.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a view showing an embodiment of the present invention. FIG. 1A is a sketch of the stick, and FIG. 1B is a sketch of a stick to be aligned. A lower cam 5 installed with its head slightly projecting from the upper surface of the two inclined rails 3 and an upper cam 4 installed above the rail 3 at a fixed interval from the lower cam 5; 5 and the upper cam 4 are provided as two pairs. The horizontal dimension V and the vertical dimension W of the sticks 6 to be aligned may be V ≠ W (rectangular section) or V = W (square section).

FIG. 2 is a side view showing the positional relationship between the inclined rail 3, the upper cam 4 and the lower cam 5. As shown in FIG. Upper cam 4
The lower cam 5 is formed in a shape in which a circular or elliptical cam surface is projected in four directions. The inclination angle X of the rail is 3
When the horizontal dimension V and the vertical dimension W of the stick 6 are used, the gap Y between the upper cam 4 and the rail 3 is W <Y <V, Y.
<2W. The lower cam 5 has its head slightly above the rail 3, and the gap Z with the upper cam 4 is adjusted so that V <Z at the maximum and W <Z <V, Z <2W at the minimum. As shown in FIG. 2, the upper cam 4 rotates clockwise, and the lower cam 5 rotates counterclockwise.

FIG. 3 is a diagram for explaining the operation of the present invention, and FIGS. 3A to 3E show the operation order. That is, the sticks 1 that are separated are the rails 3 that are inclined,
A state in which the upper cam 4 and the lower cam 5 are aligned in a line using the synchronous rotation of the lower cam 5 is shown. First, in FIG. 3A, the separated sticks 1 blocked by the upper cam 4 and the lower cam 5 are lifted by rotation of the cams. Then, the stick at the tip becomes in a state where the stick easily falls down as shown in FIG. Next, as the rotation of the cam proceeds as shown in FIG. 3C, the stick comes off the cam and falls down. The fallen stick passes below the upper cam 4 as shown in FIG. Since this series of operations is performed continuously, the lower end side of the inclined rail 3 is in the state of the stick 2 arranged in a line as shown in FIG.

[0009]

As described above, according to the present invention, since the sticks can be automatically aligned, there is no need to rely on humans, and the production equipment that requires the alignment of the sticks is
This has the effect of enabling full automation.
