Description

[Detailed description of the invention] (Industrial application field) The present invention is a method for holding roll-shaped plastic bags, which are often found in supermarkets, etc.
This relates to a so-called roll holder.

(Prior Art) Conventionally, plastic bags are often used in supermarkets and the like to store purchased items, but these plastic bags are generally rolled into rolls, and each plastic bag is There are perforations where one piece is separated.

This rolled plastic bag is held by a roll holder and can be cut out one by one.

(Problems to be Solved by the Invention) The conventional roll holder described above, however, has two major problems.

One is that the work of attaching a new roll to the roll holder is unexpectedly difficult.

In conventional roll holders, when attaching and detaching the core body, which is the member to which the roll is attached, to the frame body, it is necessary to tilt the core body to attach and detach it due to the relationship between the length of the frame body and the core body. It was hot.

If the roll is used up and the core is lightweight, it is relatively easy to attach and detach the core to the frame 2 by tilting the core, but on the other hand, attaching a new roll to the core with one hand, The work of attaching the core body to the frame body in an inclined position is difficult because the roll is heavy.
It is very tricky and is also very dangerous as the roll may slip off the slanted core.

Another problem is that the plastic bag cannot be cut properly.

In conventional roll holders, the braking body that controls the rotation of the roll also serves as a cutter when cutting the plastic bag. Therefore, if the roll is new and has a large self-weight, the roll will be prevented from rotating more than necessary by the brake, and the perforated area between the plastic bags sandwiched between the heavy roll and the brake will is in a state where it is easy to break.
Therefore, when the perforation part comes out from between the roll and the braking body, the perforation part breaks, and when you try to pull out the next plastic bag, there is no part to pinch. This made it extremely difficult to pull it out.

On the other hand, if there is only a small amount of roll left and it becomes lighter, the rotation cannot be controlled by its own weight due to its light weight, and the roll will rotate without the perforations being cut, resulting in more poly than necessary. This results in the bag being removed. Therefore, it was necessary to use both hands, such as holding the roll while cutting it. Furthermore, there are some systems that simply have rollers inserted into the braking body, but these have had problems such as lack of braking effect.

This is not only because the roll is lightweight, but also because the shape of the brake body is usually cylindrical, which is not suitable for the function of a cutter.

(Means for Solving the Problems) The present invention has been devised to solve the above-mentioned problems, and has the following configuration.

A roll holder 1 according to the present invention has a frame 2 in which the upper ends of a pair of side rods 5 facing in parallel at a constant interval are connected by a locking rod 7 having a locking portion 8.
A braking body 3 connects the lower part of the frame body 2, and a hole 9 is formed at one end through which one of the pair of side bars 5 is inserted, and a hole 9 is formed at the other end into which the other of the side bars 5 is inserted. The core body 4 has a groove 10 formed therein and is movable up and down between the side rods 5 in a horizontal position.

Of the pair of side rods 5, a part of the side rod 5 on the split groove 10 side of the core body 4 is protruded and curved outward to form a protrusion 6 for attaching and detaching the roll, and the core body The groove 10 side of the braking body 3 is positioned so as to be inserted into the protrusion 6 and can be attached to and detached from the frame 2, and the central part of the brake body 3 is positioned to protrude forward in a mountain shape. The distal end portion is formed as a cutter 14, and a cylindrical roller 15 is inserted through a portion of the brake body 3 other than the cutter 14.

The brake body 3 has a cylindrical shape or a round bar shape, and the inner diameter of the roller 2 inserted therein is set to be slightly larger than the outer diameter of the brake body 3.

(Function) The roll holder 1 according to the present invention is used in the following manner.

The roll 13 attached to the core body 4 disappears,
When a new roll 13 is required, the core body 4 is lifted upward while maintaining its horizontal position. Core body 4
The split groove 10 side of the groove 10 is inserted into the protrusion 6, and the split groove 10
When it comes off from the side rod 5, stop lifting it upward and rotate the split groove 10 side in either direction. As a result, the groove 10 side of the core body 4 is removed from the frame body 2. At this time, since the side rod 5 is inserted and assembled into the hole 9 side of the core body 4, the entire core body 4 does not come off from the frame body 2.

A new roll 13 is attached to the core 4 with the groove 10 side of the core 4 detached from the side rod 5.
At this time, since the hole 9 side of the core body 4 is assembled, the roll 13 can be attached while keeping the core body 4 in a horizontal state. Therefore, the roll 13 is easy to install and does not slip off the core 4.

Once the roll 13 is attached to the core body 4, next,
The groove 10 side of the core body 4 is inserted into the protrusion 6,
Move it downward while maintaining the horizontal position, and the core body 4
The split groove 10 is aligned with the side rod 5 below the protrusion 6, and the roll 13 is moved downwardly until it comes into contact with the brake body 3 while maintaining a horizontal posture. This completes the attachment of the roll 13.

Next, cutting of the roll 13 will be explained below.

First, when the tip of the roll 13 is pulled, the perforation portion is placed above the tip of the cutter 14. At this time,
The roll 13 located on the brake body 3 has an inner diameter slightly larger than the outer diameter of the brake body 3, and is rotated with a light force by the action of a roller 15 that is rotatably inserted through the brake body 3. do.

Next, in order to cut out the perforation portion, a tension force is applied to the cutter 14 in the folding direction to the roll 13. As a result, the perforation portion is cut off by the tip of the cutter 14.

The tip of the cutter 14 has a mountain shape and protrudes upward, so the force for cutting the roll 13 is
Concentrate on that one point. Therefore, it is easy to cut out and will definitely achieve its purpose.

Further, since the cutter 14 protrudes forward from the brake body 3, the tip of the roll 13 cut by the cutter 14 is closer to the cutter 14 than the brake body 3.
It will protrude by the length of the protrusion. Therefore,
The tip of the roll 13 can be pulled out by pinching the protruding part, which solves the problem of the conventional roll 13 being difficult to handle because there is no pinching part.

Furthermore, since the cutter 14 is located at the center of the brake body 3, the pulling force when cutting the roll 13 can be applied from right to left, from left to right, or directly in front of the eye. , right-handed people, left-handed people, anyone can use it easily.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1, 2, and 3. Figure 1 is a front view, Figure 2 is a side view, Figure 3 is the core body 4 and side rod 5.
FIG.

The locking portion 8 is formed by molding both ends of the locking rod 7 into an upward curve, and supports the roll holder 1 by suspending this curved portion from a protrusion. Note that this curved portion may be fixed to a protrusion and suspended.

This locking portion 8 is not limited to being formed only at both ends of the locking rod 7. For example, one locking portion 8 may be provided at the center of the locking rod 7. 7 may be made into a mountain shape, and the center portion thereof may be used as the locking portion 8.

The hole 9 in the core body 4 is circular and set to be slightly larger than the diameter of the side rod 5.

The roll 13 attached to this core body 4 is attached to the collar 1
1 is shown wound around a paper tube 12 having a roll 13. Therefore, a storage space 16 for the collar 11, which moves downward as the roll 13 becomes smaller, is provided by inwardly curving the side rods 5. .

The brake body 3 is made of a rod, connects the lower part of the side rod 5, and except for the central cutter 14, the roller 15 inserted therein rotates when the roll 13 rotates, thereby smoothing the rotation of the roll 13. ing.

The cutter 14 here has a shape in which the central portion of the brake body 3 is bent forward diagonally downward and then bent diagonally upward. In this way, by oriented the tip of the cutter 14 upward, the roll 13 can be more easily cut.

Incidentally, the frame body 2 is constituted by a rod body here.

Various holes 9 in the core body 4 are conceivable.
Three examples are shown in FIGS. 4, 5, and 6.

In FIG. 4, the hole is shaped like an elongated hole, which allows the core 4 to move in the left-right direction with room to move up and down, making it easier to move up and down, and also allows the core 4 to tilt when necessary. Further, the diameter of this hole 9 is set to such an extent that the split groove 10 does not come off from the side rod 5 due to the inclination of the core body 4.

5 and 6 show a hole 9 formed by closing the cutout groove 17 with a removable plate piece 18 and a bolt 19. FIG. By doing this, if necessary, the core body 4 can be attached to the side rod 5.
It can be removed more easily.

(Effect of the invention) In this way, the roll holder according to the invention has
While one end of the core remains attached to the side rod, the other end can be easily removed from the frame, and the roll can be attached and detached easily and safely.
This solves the problem of the conventional method where it was difficult to attach and remove the rolls, which could be dangerous if the rolls were dropped.

In addition, the roll holder according to the present invention has a roller attached to the brake body, so the roll can be rotated and taken out with a light force, and the cutter protrudes from the center of the brake body, so the roll can be cut off reliably. In addition, the tip of the roll after cutting protrudes so that it can be easily pinched, making it easy to use for anyone.

Furthermore, the present invention achieves the above-mentioned effects by forming the protrusion and the cutter by simply bending and forming a part of the side rod and a part of the brake body, and the structure is extremely simple. , it also exhibits excellent effects that greatly contribute to improving productivity.
