Description

[Detailed Description of the Invention] Technical Field The present invention relates to a can opener for opening cans of foodstuffs, etc., and more specifically to a can opener for opening even large, approximately rectangular cans for commercial use.

Prior Art Conventionally, in the can opener of the above type for opening cans, the edge of the can lid is pressed against the lower end surface of the curled part that is bent and crimped against the upper part of the outer peripheral surface of the can body, and the can opener is moved in a predetermined direction. A drive wheel that rotates the can, and a cutter that cuts into the can lid along the inner circumferential surface of the can and opens the can as the can rotates, the can being supported cantilevered by the drive wheel and the cutter. Although it is configured to automatically open the can,
When opening large commercial cans that are approximately rectangular in shape using a multi-cutting device, the weight of the cans reaches up to 9 times, and as the cans rotate, the cutter and the drive wheel move away from the support position. Since the distance to the center of gravity changes, it is extremely difficult to cantileverly support the canned food by the drive wheel and the cutter, and the canned food cannot be opened automatically.

OBJECT OF THE INVENTION In view of the above-mentioned drawbacks of the prior art, it is an object of the present invention to provide a can opener that has a simple configuration and can automatically open even large, approximately rectangular cans for commercial use.

Structure of the idea Hereinafter, the present invention will be explained according to examples.

FIG. 1 is a front view schematically showing a can opener device according to the present invention, FIG. 2 is a left side view of FIG. 1, and FIG. 3 is a sectional view taken along line A-A in FIG. is the electric motor built into case 2 (
Not shown.

), the drive wheel 4 rotates the canned food 3 in a predetermined direction by press-contacting the lower end surface of the curled portion 3b of the can lid 3a bent at the upper outer periphery of the canned food 3, which will be described later. 4 is pivotably supported on the case 2 in the upper position, and when it is pivoted downward,
When the start switch 5 is turned on, a cutter 6 having a blade is fixed to the opposite rotation direction side of the drive wheel 4, and the cutter is moved against the can lid 3a of the canned food 3 supported by the drive wheel 4. It consists of a presser body 7 that is bitten along the inner peripheral surface of the can body 3c.

A presser bar 8 is fixed to the case 2, which abuts against the upper end of the canned food 3 and restricts the vertical movement of the canned food 3 as the can progresses. A protrusion 2a is formed to restrict contact of the drive wheel 4 with the outer peripheral side surface.

The fixing base 9 is attached to the left end side in the figure, and is attached to the curled portion 3b.
A support stand 10 has a height such that it presses against the upper end of the drive wheel 4, and a roller 11 that moves along a rail portion 9b whose front and rear walls of a recess 9a formed on the right side of the drawing has a substantially U-shaped cross section. and a movable table 12 which is pivotally supported and is movable back and forth in the direction of the support table 10.

A rotatable turntable 13 is attached to the movable stand 12, and the can opener main body 1 is fixed to the turntable 13 at least at an inclination angle θ, which will be described later, with respect to the vertical line.
Or it is attached removably.

Further, on the support stand 10, a pedestal 14, which has a shape corresponding to the lower part of the canned food 3 and on which the canned food 3 is fixedly placed in an extended position, is rotatably supported at its center of gravity.

The canned food 3 has flanges formed around the top four circumferences, and
A can body 3c is formed with reinforcing ribs 3d formed at the corners of the flange and has an open top, and after storing foodstuffs etc. in the can body 3c, along the four circumferential and inner and outer sides of the can body 3c. It consists of a can lid 3a whose four peripheral edges are bent and crimped and which closes the upper opening of the can body 3c.

The above-mentioned curled portion 3b is a bent portion that is bent and crimped onto the outer surface of the can body 3c on all four sides.

The inclination angle θ is between the vertical line of the flange and the curled portion 3.
This is the angle between b and a line passing through the top of the rib 3d.

Next, the operation of this embodiment will be explained with reference to FIG. 4 and FIGS. 5A to 5D.

After placing the canned food 3 in a fixed position on the pedestal 14, the can opener body 1 is moved in the direction of the center of gravity P of the canned food 3.
While reciprocating by an appropriate distance and rotating, the lower end surface of the curled portion 3b is brought into contact with the upper end of the drive wheel 4, and the upper end of the curled portion 3b is brought into contact with the presser bar 8.

When the presser body 7 is rotated in the direction of the solid arrow in FIG. 3 in the above state, the presser body 7 cuts the cutter 6 into the can lid 3a along the inner peripheral surface of the can body 3c, and The start switch 5 is turned on to rotate the drive wheel 4.

As the drive wheel 4 is rotated, the can 3 is rotated together with the pedestal 14, and the can body 3c and the can lid 3a are cut and separated by the cutter 6, and the can is opened.

In addition, since the blade of the cutter 6 is installed in an inclined state with respect to the can opening direction of the can lid 3a, the pressing stress acting on the cutter 6 as the can progresses to open the can can cause the blade to bite into the can lid 3a, and The ON state of the starting switch 5 is maintained by the presser body 7, and the canned can 3 can be opened automatically.

As shown in FIGS. 5A to 5D, when the can 3 is rotated around its center of gravity P as the can is opened, the can opener main body 1 corresponds to the distance from the center of gravity P to the can opener position. While reciprocating in the direction of the center of gravity, the can 3 is maintained in a supported state by the drive wheel 4 and the cutter 6 while rotating, and the can 3 is automatically opened each time.

When the corner of the can opener 3 is positioned on the drive wheel 4 as the can open progresses, the can opener main body 1 is tilted forward by at least an inclination angle θ with respect to the vertical line on the fixed base 9. As shown in FIG. 4, the ribs 3d are prevented from coming into contact with the drive wheel 4, and the cans are opened at a constant can opening speed.

Therefore, this embodiment is a large can that is difficult to open while cantilever supported by the cutter 6 and the drive wheel 4, and the distance from the center of gravity P to the can opening position changes as the can progresses. It is also possible to automatically open canned food for commercial use having a substantially rectangular shape at a constant opening speed.

It should be noted that the present invention can also be implemented with a structure in which the support stand or the pedestal can be adjusted in the vertical direction according to a plurality of types of canned goods having different heights.

Effects of the Invention As explained above, the present invention includes a drive wheel that presses against the curled lower end of a can to rotate the can, and a cutter that cuts the can lid in accordance with the rotation of the can at a position close to the drive wheel. a can opener body having a can opener body; and a support base that rotatably supports a canned food at a position approximately at the center of gravity of the canned food and also positions a curled lower end surface of the canned can on the drive wheel; a fixed base that is rotatably mounted and capable of reciprocating in the direction of the canned food; This is a can opener device that can automatically open even large, approximately rectangular canned food for commercial use, with a simple configuration in which the rotating can opener body opens canned cans.
