Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a continuous chopstick processing device for chamfering and processing medium grooves on disposable chopsticks.

(Prior art and its problems) The structure and operation of chamfering in the present invention are explained in the fourth section.
This will be explained with reference to FIGS.

A in the figure is a chamfering plane, and four chamfering planes A are combined in a ring shape to form a transfer path 5 in the center thereof.

Each chamfering plane A is connected to a substantially triangular prism-shaped plane stand A ₁ and a transfer path 5.
A cutout A ₂ constituting the blade and a diagonal hole A ₃ for attaching the plane blade are provided, and the plane blade a is inserted into the diagonal hole A ₃ so that the cutting edge of the plane blade a faces the transfer path 5. . On the loading side of the plane stand A ₁ of each chamfering plane A, a guide fitting A ₄ is provided so that the loading side is wide and gradually narrows, and the lower side is shorter than the upper side of the chamfering plane A. to form.

The notch _A2 constituting the transfer path 5 of each chamfer plane A is narrow on the carry-in side and wide on the carry-out side, and is designed to match the external slope of the blank C of disposable chopsticks.

Each plane blade a is provided so as to protrude into the transfer path 5 by the amount of the chamfer, and chamfers each of the four corners of the semi-finished product C.

In the figure, reference numeral 19 is an elastic body such as a rubber band, and this elastic body 19 is stretched around the chamfering plane A, so that the semi-finished product C fed into the transfer path 5 is placed in each notch _A2 . Make sure it is pressed against each side.

Further, reference numeral 6 in the figure is a guide stand, which forms a similar transfer path 5 so as to be continuous with the transfer path 5 formed by the chamfering plane A.

The operation of the chamfering process will now be explained.

Chamfer the thick side of the semi-finished product C using the guide fitting of the plane A.
When pushed into _A4 , the upper chamfer plane A is expanded and carried into the transfer path 5, as shown in FIGS. 6 to 8. The upper chamfering plane A starts chamfering with the plane blade a, and chamfering waste is discharged from the diagonal hole _A3 . Furthermore,
When the semi-finished product C is transferred, the lower chamfering plane A is expanded and similarly chamfers the lower part. Since the surface of each notch A ₂ is pressed against the blank C, the input side of each chamfering plane A gradually narrows along the outer slope of the blank C, until it is chamfered all the way to the tip of the blank C. Ru.

The chamfering process described above has the following disadvantages.

Since the transfer interval between the semi-finished products C and C is not uniform and may be wide or narrow, the first semi-finished product C is chamfered in order from the thickest side, and the last thinner one is chamfered. During this process, when the next semi-finished product C is transferred, each chamfering plane A will expand at that point. Therefore, in the first half-finished product C, the planer blade a separates, leaving an unchamfered portion at the tip, resulting in an unfinished product.

(Technical Problem) The present invention has been made in view of the above-mentioned conventional circumstances. The purpose is to ensure it.

(Structure) The disposable chopsticks continuous processing device of the present invention has rollers of different diameters disposed on a transfer path for semi-finished products so that the circumferential speed increases sequentially from the carry-in side to the carry-out side. It is characterized in that a movable chamfer plane and a middle groove plane are appropriately arranged in between.

(Example) An embodiment of the present invention will be explained with reference to FIGS. 1 to 3, and the detailed structure of the chamfering plane A in the figures is shown in
It is the same as that shown in FIG. 8, and its explanation will be omitted.

In the figure, reference numeral 20 denotes a substantially table-shaped machine frame, and support plates 21 are provided in an upright manner at the front and rear of the upper surface of the machine frame, respectively.
A pair of first, second, third, and fourth rotation shafts 11, 12, 13, and 14 are provided on the support plate 21, one on the upper side and one on the upper side, respectively.

The horizontal spacing between the rotating shafts 11, 12, 13, and 14 is approximately equal to the length of the blank C, as shown in FIG. In addition, each rotating shaft 11, 12,
13 and 14 are each provided with a sprocket S,
They are connected to each other by a tube T, and a pulley P is provided on the second rotating shaft 12, which is connected to a drive motor M provided at the bottom of the machine frame 20, and rotated in the rotational direction as shown in FIG. Ru.

First, second, third, and fourth rollers 1, 2, 3, and 4 are provided on each of the rotating shafts 11, 12, 13, and 14, respectively, and the rollers 1, 2, 3, and 4 rotate the transfer path. 5 is composed.

Each of the rollers 1, 2, 3, and 4 is configured to gradually increase in diameter from the first to the fourth roller. By doing this, each roller 1,
Gradually increase the circumferential speed of 2, 3, and 4.

In other words, since the circumferential speed of the rollers at the rear stage is faster than the roller at the front stage, the semi-finished product C sandwiched between the rollers at the rear stage is faster than the semi-finished product C sandwiched between the rollers at the front stage, and the semi-finished product The distance between C becomes wider.

A chamfering plane A for rough cutting is provided between the first and second rollers 1 and 2, a chamfering plane A for finishing is provided between the second and third rollers 2 and 3, and a chamfering plane A for finishing is provided between the third and fourth rollers. rollers 3, 4
A middle groove plane B is arranged between the two.

Each chamfer plane A has a structure similar to that shown in FIGS. 4 to 8, and is divided into a finishing type and a rough cutting type depending on the amount of the plane blade a.

The medium groove plane B has plane blades b arranged vertically and oppositely, and is used to form medium grooves along the cracks of the blank C.

A semi-finished product hopper 15 is provided on the carry-in side of the transfer path 5, and a processed product hopper 22 is provided on the carry-out side.

The blank hopper 15 is a substantially cubic frame with an open top, and stores the blank C so that the side in the direction of movement of the transfer path 5 is thicker.

An inclined plate 17 is provided from the lower part of the semi-finished product hopper 15 to the input side of the transfer path 5, and a presser plate 18 is provided on the inclined plate 17 to arrange the semi-finished products C in a height row. The semi-finished product C is supplied from the hopper 15 to the transfer path 5.

The workpiece hopper 22 is a generally cubic frame with an open top surface, and is used to store the workpiece D.

(action, effect) According to the present invention, there are the following functions and effects.

Since the circumferential speed is made to increase sequentially from the carry-in side to the carry-out side, the intervals between the semi-finished products can be widened.

Therefore, while the tip of a blank product is being chamfered, the next blank product will not be carried in and the chamfering plane will expand and become unprocessed.
