Description

[Detailed description of the invention] (Industrial application field) This invention relates to canning.

(Prior Art) Many canned butiin products have been known so far, but few have been found that are actually satisfactory. In many cases, the blade becomes stuck and stops moving,
The cut edges tend to become jagged and pose a danger to the user. Furthermore, since fine metal debris is generated, the contents of the cancer may be contaminated by these.

(Problem F11 to be solved by the invention) Accordingly, it is an object of the present invention to provide an improved solution which can sufficiently and easily perform the functions that the prior art has failed to accomplish.

According to the invention, h1/υ is intended to be cut around the lower side of its lid and lip so that the lid and lip are separated from the rest of the kettle. A hand-held saw cutter is provided, which includes a pair of main body members rotatably connected to such lυ cutters IJ and TJi, and a rotatable cutter formed integrally with each of these main body members. The handle extends to a position normally away from the fulcrum and is movable between the closed position and the closed position, allowing the user to grasp it with one hand or knee to set the closed position, and the lip of the lid of the cancer. The hand is held in contact with the drive wheel, and through this drive wheel the hand can be rotated around the upper part of the cutting operation with the axis of rotation and the cutting operation position. It forms a nip with the drive wheel at the top, pushes it against the side of the cancer, passes it through, and cuts around the cancer as the cutting wheel pivots around the cancer. A cutting wheel with a cutting blade and a cutting wheel on the drive wheel.
At the cutting operation position where the B1 blade is pressed against the side surface of the can and penetrates it, the small cutting eel extends approximately radially from the drive wheel, for example, relative to the axis of rotation of this drive wheel. Can be moved between the non-cutting operation position and 4f J,) 12 on one side of the main body member! The plate is movably supported and the cutting wheel is rotatably mounted, and the mounting plate 1 and the mounting plate 1 are also supported when the cutting wheel is in the closed position. t
When the handle is turned in this direction tJ (turn υI L, /j, it is moved to the cutting operation position, and when the handle is turned from its closed position rotation limit to the closed position ()), it is then moved to the non-cutting operation position. It is equipped with a cam gap (14) for moving to.

According to the lv cutter with such a configuration, the cut is ``a very rough cut l that is not often jagged'' and metal scraps are removed.

Furthermore, it is common to carry out the cutting operation without any problem even when the can is severely damaged or dented. It can be used for cylindrical cans J3J and other ellipsoidal or rectangular cans J3J.

Preferably, the axis of the manually rotatable shaft on which the drive wheel is mounted is aligned with the rotation axes of the two main body members.

The cutting wheel is moved through the cutting operation position r1 by means of a cam R by rotating the main body member only slightly, for example by setting the main body member at an angle of up to 30°. The rotation of the body member can be limited in its range, for example by cutting the cutting nip between the drive wheel and the cutting wheel. British Patent Application No. 83 (No. 13320, Publication No. 21181) filed by the same applicant, which must be avoided.
It has advantages over Kan-kiri described in No. 34.

A cam (one structure is formed on the main body member on the side that does not slidably support the mounting plate, and one is a substantially linear groove inclined at a predetermined angle with respect to the sliding wheel of the brake 1). and a pin projecting from the mounting plate into this groove, and the arrangement of such grooves and pins can also be reversed. (al, tb) is inclined at an angle of about 15 degrees with respect to the oblique direction, but such an angle is, for example, 10 to 15 degrees.
It can be changed within a range of 30°. In fact, if such a vortex is formed in the main body member on the side that does not support the mounting plate, the relative The angle is when the handle is closed (0
As the handle moves from open to open, the angle C changes. That is, as the handle moves from its closed position to its closed position, the angle increases by J: ), so that as the handle moves from the closed position to the closed position, the cutting wheel moves to the mounting play 1-.
The relative advance is initially rapid, but as the cutting wheel approaches the cancer, the forward movement slows down, providing the advantage of passing the can through ξ''j with a relatively large force.

In addition, as mentioned above, an upright protective member is integrally formed on the main body member on the side that does not support the mounting plate 1-, and this protective member prevents accidental contact with the cutting wheel before use. It's a shame to prevent it from being put away.

Furthermore, when the cutting wheel moves to the non-cutting position, the main body member on the side that does not support the mounting plate 1- is used to remove the cut lυ from the cutting wheel and the drive wheel.
It is preferable to provide an abutment portion which functions to remove the material from the nip, i.e., release it. Such an abutment may also be an edge formed in the direction of movement of the cutting wheel between the operating position 1f7i and the non-cutting operating position l; The end portion of the protective member can be configured to have a shape.

The drive wheel and the gear connected thereto can be driven manually, for example, via a two-armed crank mounted on the free end of the shaft. In addition, instead of this, the hs / υ cutter can be replaced with a hand-held electric gun cutter,
A housing for an electric motor can be added to one of the handles so that the shaft can be driven by this electric Tanabata.

(Example) Next, one embodiment of the present invention will be described with reference to the drawings.

The illustrated Kankiri 1o has two main parts! 41283 and 14. These body members 12° 14 are U-shaped around a hollow upright cylindrical insertion portion 15 provided in the other body member 12, which projects into a circular hole 15a formed in one body member 14. It is possible to rotate.

a and extends in the axis/J direction (see Figure 4). The main body member 12.14 is rotatable between the closed position shown in FIG. 1 and the closed position shown in FIG.

The main body portions U12, 14 are integrally formed with IC handles 12a, 1/18 and J3, respectively, and these handles 12a, 14a extend in a direction 39 angular from the axis of the shaft 16, as shown in FIG. In the closed state, one shaft is formed in close contact with the other and in a parallel state. Conveniently, the body member 12.14 is formed from a synthetic plastic material, such as λ, for example polypropylene.

A crank 20 with two 7-arms for manually rotating the shaft 16 is integrally formed at one end of the shaft 16. A metal reinforcement @22 is embedded in the shaft 16, and one end of this reinforcement @22 is 9 of 111111G.
It protrudes slightly beyond the 21st part and is taken up by the drive wheel 24. The lip V28 of the lid 27 of the drive wheel 24 (round shape, can 29) (see Figure 6)

The sleeve 34 consisting of is rotatable.
It's getting better. Connected to the sleeve 34 at its outer position is a metal cutting wheel 36, which has a sharp circular cutting blade 37 on its right side. The sleeve 34 is intended to abut the lip 28 of the can 29 and rotates as the cutter 10 moves around the cutter 29 and the cutting wheel 36
Since both the sleeve 34 and the sleeve 34 are rotatable,

An upright U-shaped protection part shrine 39 is integrally formed on the main body member 12. For this reason, the user is prevented from being accidentally cut by the cutting wheel 36. The protective portion 39 is formed at its end in an inclined shape with respect to the shaft 30a. At the final stage of the cancer cutting operation, the cut lid is held between the cutting wheel 36 and the drive wheel 24. After being separated, the cutting wheel is pulled, and the lid of the cutting wheel 3G comes into contact with the first joint 39a, is forcibly pulled away from the vicinity of the blade of the cutting wheel 3G, and is automatically released for disposal.

The bundling and cutting wheel 36 is also connected to the drive wheel 27
'1 is taken beyond the lip 28 of the cutting wheel 36 (4), so that the cutting blade 37 of the cutting wheel 36 is separated from the drive 71 (a distance of -1 - minutes from the eel 24, as shown in FIG. 3). From the non-I/J t!Ji operation position, cut IfJi blade 3
7 slightly overlaps the drive wheel 2G, the cutting operation state shown in FIG. 1 is reached.

Since the structure 44 is formed on the main body member 14, the iM 4
The angle relative to the sliding direction of the metal plate 30 in No. 4 is such that the handles 12a and 14a are at the IVJ position lj/? Dotin i1. 3, which changes as you move between n.
In other words, the angle J,) is the angle at which the handles 12a, 148 move from the closed position to the closed position, and the mechanical characteristics also change. 14.As a moves from the closed position to the closed position, the metal plate 30 is cut with a J and the n wheel 36
moves forward relatively quickly at first, but as it approaches the cancer 29, its forward movement slows down, and the advantage is that it can pass through the side of the cancer 29 by applying a relatively large force L″1. .

FIG. 6 also shows the state of the cutting operation, in which the cutting blade 37 has passed through the upper end of the cylindrical side surface of the can 29 directly adjacent to the lid 27. Therefore, when the cylinder 29 is cylindrical, when the cylinder 29 is cylindrical, it is driven to rotate in a circular manner around the cylinder 10 t; It will be cut into a circle with the shaped side. Once such a circular cutting operation is completed, the upper part of the cancer is lifted completely apart and the space between the cutting boiler 36 and the drive wheel 24 is removed. handle 12a,
14a is shown in Figure 3! When it reaches the 711 position, it is cut out and comes into contact with the 1 earth azalea 339a and is removed.

A metal brake 45 is embedded in one side of the main body member 72, and this plate 455 is used to prevent the plastic material composing the main body member from coming into contact with the rim of the cancer during the cutting operation. J, will you protect this in case of eel?
It is provided. Further, the surface of the plate 41) is slightly protruded from the wooden shrine 12.

In order to help maintain the cutting position during the cutting operation, the main body member 12 has a t that is approximately parallel to the axis of the 1 draw 1 [5].
A small protrusion 46 that protrudes at J is integrally formed.

This protrusion/! The end portion of No. 6 serves to maintain the height of the J8 cutout on the upper surface of the lid 27.

The cutter 10 as shown in Figure 1 is easy to manufacture and operate, and is effective in keeping the cancer clean and biological.
