Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a screw cap removal device used when removing a screw cap that is firmly screwed onto a container body.

[Conventional technology and problems]

In recent years, a wide variety of bottled foods have come on the market, and the bottles that house these foods have screw caps that are tightly screwed together to maintain the freshness of the food sealed inside. When removing a screw cap screwed together in this way, the usual method is to secure the container body with one hand and twist the screw cap with the other hand. In many cases, it cannot be opened easily using other methods. Particularly for women, children, the elderly, etc., who have weak physical strength, such operations are extremely difficult.

On the other hand, tools in the form of pliers are commercially available for removing screw caps. In this device, the bottle cap is held between iron gripping parts similar to the jaws of a vise, and the screw cap is twisted open using the principle of leverage, but this type of device also does not function satisfactorily. The reason for this is that the screw cap is held in place with the grip force of the hands, like pliers, so if it is too tightened, the screw cap will stick to the bottle body and cannot be turned, while if it is too loose, it will slip between the clamping part and the screw cap. The tightening condition is delicate and difficult to control, and at the same time, you have to perform this operation with one hand while also twisting the instrument horizontally while holding it in this state. However, these operations are extremely difficult. Additionally, the clamping part is difficult to engage with the screw cap, and may easily come off during operation. Furthermore, when twisting the screw cap, if the bottle body is large and difficult to grasp, or if your hands are wet with oil or water, you may not be able to secure the bottle body, causing problems such as the bottle body rotating together with the screw cap. This is because

In addition, when the operating lever 8 is in a free state where the pressure is released,
The switch 13 is automatically returned to the neutral position as shown in FIG. 1 by the elastic action of the upright member 13a and the slope resistance of the V-shaped member 13b attached to the front of the upright member 13a. Also 1
Reference numeral 4 designates an operating lever for rotating the lever 8 clockwise to operate the pulley 11 and the wheel 12 in a downward direction, and a pressing plate 15 is provided at the front end. 16 is a V wound between pulleys 2 and 11.
It is a belt, and 17 is an adjustment screw for determining the downward movement stop position of the press plate 10.

Upright portion 2 provided at the rear of the case 00
0, a shaft 21 having a rectangular cross section is arranged so as to extend in the vertical direction and to be freely rotatable. A gear 22 and a flat plate 23 are non-rotatably attached to the lower part of the shaft 21 at positions above and below the friction wheel 12 and spaced apart from the friction wheel 12.
Note that the gear 22 meshes with the output shaft of the motor 24.

Inside the upright portion 20 of the case 00, guide grooves 25 are provided on both left and right sides,
Rollers 26 are inserted into these grooves 25 so as to be able to freely roll up and down in two stages, and a vertically movable case 27 is supported by these rollers 26. Further, the vertically movable case 27 is urged upward by a spring (not shown).

A press plate 28 is rotatably attached to the upper part of the vertically movable case 27 via a pin 29, and this press plate 28 is urged upward by a spring 30.
A switch 31 provided between the pressing plate 28 and the case 27 is normally in an "open" state. The switch 31 is used to start and stop the motor 24.

Further, a shaft 32 is rotatably disposed inside the vertically movable case 27 so as to pass through it in the vertical direction. A hollow cone (screw cap engaging member) 33 is non-rotatably attached to the lower end of the shaft 32, and a lining material 34 made of rubber or the like is adhered to the lower surface of the hollow cone 33. The hollow cone 33 is arranged concentrically on the center line l of the bottle body positioned by the gripping member 3, and is driven by the gear 22, the shaft 21, and the vertical movement case 2 by the motor 24.
7 and is rotated via a ring gear 35 (see FIG. 5), which is rotatably supported by the shaft 21 and fitted onto the shaft 21 so as to be vertically movable, and intermediate gears 36, 37, and 38.

Next, the operation of the screw cap removal device having the above structure will be explained.

On the horizontal stand of the case 00, the gripping members 3,
Set the bottle body between steps 3 and 3.

Next, press the pressing plate 10, rotate the operating lever 8 counterclockwise in FIG. 1, and turn the switch 13.
is switched to the "closed" state, and the friction wheel 12 is brought into contact with the upper gear 22 (see FIG. 3). Then,
The motor 24 is driven, and its rotational force is transmitted through the gear 22
It is transmitted to the friction wheel 12 via the V-belt 16 and the pulley 2, and is further transmitted to the threaded rod 1 to rotate the threaded rod 1 in a predetermined direction. Along with this, the pair of gripping members 3 come close to each other and grip the bottle body A between both gripping parts 6. At this time, the grip part 6
are formed in a V-shape and are arranged at different heights, so that no matter what diameter the bottle body A is, it is symmetrical, as shown in Figures 6 to 8. Even if it has an irregular shape, it can be strongly gripped. Furthermore, even if the pressing plate 10 is continued to be pressed after the gripping member 3 grips the bottle body A, slipping occurs between the gear 22 and the friction wheel 12, causing the gripping member 3 to press the bottle body A more than necessary. No problems will occur. Furthermore, the gear 2 of the friction wheel 12
2 is predetermined so as not to exceed a certain value by setting the lower limit of movement of the press plate 10, which is adjusted by the adjusting screw 17.

In this way, the gripping of the bottle main body A is completed, but at that point, the pressing on the pressing plate 10 is stopped. Then, the operating lever 8 is operated by the elastic force of the upright member 13a and the V
The slope resistance of the character-shaped member 13b returns it to the neutral position, the switch 13 enters the "open" state, and the friction wheel 12 separates from the gear 22. At this time, the bottle body A is maintained in the gripped state due to the frictional force between the gripping member 3 and the threaded rod 1.

Next, press the pressing plate 28 to lower the vertical movement case 2.
7 and each member attached to it are lowered. Then, first, the lining material 32 attached to the hollow cone 33 hits the upper ridgeline of the screw cap B, and when the pressing plate 28 is pushed even more forcefully, the pressing plate 28 resists the force of the spring 30 and moves as shown in FIG. The switch 31 is turned to the "closed" state by rotating counterclockwise, and the motor 24 is started. Therefore, the gear 22 is driven, and the rectangular shaft 21 coaxial with the gear 22 is also rotated in the same direction, and the rotation is caused by the ring gear 3.
5. Transmitted to the shaft 32 via intermediate gears 36, 37, and 38. As a result, the hollow cone 33 rotates counterclockwise when viewed from above, and the screw cap B is screwed open.

Thereafter, when the pressing force on the pressing plate 28 is removed, the vertically movable case 27 is separated from the screw cap B by the action of a spring (not shown), returns to the upper limit position, and waits for the next operation. Then, the pressing plate 15 is pressed, the operating lever 8 is rotated clockwise in FIG. 1, the switch 13 is switched to the "closed" state, and the friction wheel 12 is pressed against the flat plate 23. Then, the friction wheel 12 rotates in the opposite direction to that when pressed against the gear 22, the gripping screw shaft 1 also rotates in the opposite direction, and the gripping members 3 move away from each other to hold the bottle body A. move away from In this state, the bottle body A and the screw cap B can be removed.

Therefore, according to the screw cap removal device having the above structure, the operation is simple and easy, mostly just by pressing the pressing plates, etc., and does not require any skill or tricks.
It does not require physical strength and can be easily used by women, children, the elderly, etc. During use, the bottle body can be operated without touching the bottle body, so there is no need to firmly grasp the bottle body A with one hand, as when opening the lid with bare hands or using commercially available pliers-type lid opening tools. It is safe. Additionally, if you remove your hands from the devices during operation, all mechanisms will stop operating instantly, so safety is high. The vertical downward pressing force of the screw cap engaging member 33 against the screw cap is differentiated by the action of the slope on the inner surface of the hollow cone, and a binding force acts on the periphery of the upper ridgeline of the bottle cap, thereby causing the engagement. Generates a large frictional engagement force between the member and the screw cap, and at the same time creates a lever action on the outer surface of the screw cap,
As shown by the two-dot chain line in FIG. 1, the entire outer lower end of the screw cap B is caused to protrude outward, so that the screw cap B can be unscrewed more smoothly. Excellent effects such as adaptability to commercially available containers of various diameters and heights can be obtained.

Note that FIGS. 9 to 14 show modified examples of the screw cap engaging member.

That is, in the example shown in FIGS. 9 and 10, a lining fitting part 41 formed on the back surface of a hollow cone (screw cap engaging member) 40 with a U-shaped cross section by cutting and raising both sides, A plurality (for example, three) are provided at equal intervals in the circumferential direction, and a lining material 42 is adhered thereto via an adhesive or the like. With such a configuration, the lining material 42 can be saved, and the unit crimping pressure increases due to the reduction in the area of pressure contact with the screw cap B, so that the lining material 42 wraps around the ridgeline of the cap B. This has the advantage that a large frictional force can be obtained and that it can be evenly pressed onto the outer periphery of the screw cap B.

Furthermore, in the examples shown in FIGS. 11 and 12,
On the back surface of the hollow cone (screw cap engaging member) 50, a plurality (for example, three) of standing portions 51 are provided in the circumferential direction, extending from the center to the vicinity of the outer periphery and cut and raised in the same circumferential direction. Moreover, the tips of these upright portions 51 are formed at acute angles. With this configuration, as shown in FIGS. 13 and 14, the hollow cone 50 can be inserted into the screw cap B by simply inserting the tip of the upright portion 51 into the screw cap B without using any lining material. The screw can be opened with strong engagement.
