トするためのロールホルダーに関する。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a roll-shaped sheet, that is, a roll made of a strip-shaped thin film product such as film or paper wound around a core, which is pulled out so as to be rewound in required amounts. Regarding the roll holder used to set the roll so that it can be cut, it is especially suitable for long strip-shaped thin film products with perforations for breaking, such as plastic bags and packaging films, which are often used by consumers in food departments such as supermarkets. This invention relates to a roll holder for setting rolls.

新しいロールをセツトしなおす。 Conventionally, many roll holders of this type have already been proposed and actually used. In general, many of the above-mentioned thin film product rolls have a structure that includes a shaft etc. that supports the core of the roll so that it can be inserted and removed and rotated.
The consumer pinches and pulls the tip of the thin film product on the roll set on the shaft with his or her fingers, and uses this tension to rotate the roll in an unwinding manner to pull out the required amount of the thin film product and cut it from the perforation for breaking. When the thin film product on the set roll is used up, the remaining core is removed from the shaft.
Reset the new role.

ールに制動力を与えて過剰な回転を防止するよう
にした構成である。 By the way, in such a roll holder, when the thin film product on the set roll is pulled out and cut by the required amount, the roll rotates vigorously in the unwinding direction, and its inertia causes it to rotate too much, causing the thin film product to be cut out more than necessary. I was rewound and came out.
There was a problem that was extremely uneconomical. For this reason, many roll holders are now equipped with a braking function to prevent the roll from rotating more than necessary. As a typical example, a swinging or sliding type braking body is always pressed against the circumferential surface of a roll set on a shaft by an elastic member, and the friction of this braking body against the circumferential surface of the roll is applied. This configuration uses a force to apply braking force to the roll to prevent excessive rotation.

た。 However, in a roll holder provided with such a braking body, replacing and setting the rolls is troublesome, time-consuming, and inefficient. In other words, whether the braking body is a swinging type or a sliding type, the braking body is constantly pressed by an elastic member and is urged to come into pressure contact with the roll circumferential surface, so that once the set roll is removed, the core of the roll is When the roll is removed from the shaft, the braking body is pressed by the elastic member and remains in contact with the shaft, and in this state, the braking body is a hindrance and it is not possible to insert and set a new roll onto the shaft. Therefore, when replacing or setting the roll, the braking body must be reversed or retreated to a position far away from the axis against the elastic member in order to release it, and then the braking body must be returned to its original position again when the roll is replaced and set. It requires a lot of operation, and the work of changing rolls is troublesome, time-consuming, and inefficient, and it takes a lot of effort and time to insert and set rolls into roll holders, which are installed in large numbers at major supermarkets. I had a problem with this.

るものである。 In order to achieve the above-mentioned object, the roll holder of the present invention is provided with a shaft on a supporting member that supports a roll formed by winding a strip-shaped thin film product around a core so that it can be inserted into and removed from the core and rotated. A braking body is attached to the support member so as to be swingable or slidable, and is biased by an elastic member so as to be in constant pressure contact with the circumferential surface of the roll inserted and set on the shaft, and the thin film product of the roll is pulled and unwinded. A braking mechanism is provided for suppressing rotation due to inertia during the cutting operation, and a roll insertion guide is provided on the braking body of the braking mechanism, which is inclined in a direction that gradually moves away from the shaft as it approaches the roll insertion end of the shaft. With this structure, the braking body of the braking mechanism comes into pressure contact with the peripheral surface of the roll set on the shaft to prevent excessive rotation, and when replacing the roll on the shaft, the operator can directly open the braking body of the braking mechanism. Even if you don't do anything, just insert a new roll by pushing it into the shaft from one end, the roll will push the roll insertion guide, the brake will open as much as necessary against the elastic member, and there will be no problem. The setting can be completed smoothly without getting in the way, and the work of replacing and setting the rolls is made very easy.

In the above-mentioned state without performing any other operations, push down roll A from above as shown by the imaginary line in Figure 2, and insert it so that core b fits loosely into shaft 2 from its upper end. . As a result, the lower edges of the outer periphery of the roll A first come into contact with the upper end portions of the left and right roll insertion guides 11, which are inclined in an inverted V-shape, and the downward force of the roll A is applied to the roll insertion guide 11. Acts to push open left and right. Thus roll A
As it is pushed down and inserted into the shaft 2, the left and right roll insertion guides 11, together with the brake bodies 8 of the left and right brake mechanisms 4, rotate outwardly against the tensile force of the elastic member 10. Contact portion 8 of body 8
d and 8d are opened to the left and right from the shaft 2 to receive the roll A, and the lower end of the roll A smoothly passes through that part and is attached to the shaft 2 until it comes into contact with the upper surface of the roll seat 3 as shown in Fig. 3. It is inserted deeply. This completes the insertion and setting work of the roll A, and the roll A is supported rotatably around the shaft 2 on the roll seat 3 as shown in FIGS. 3 and 4, and at the same time, the peripheral surface of the roll A is Then, the abutment portions 8d, 8d of the left and right brake bodies 8 are brought into appropriate pressure contact by the biasing force of the elastic member 10, so that a braking action is performed.

When the consumer picks up the tip of the bottle with their fingers and pulls it,
The thin film product a is rotated as if being unwound around the shaft 2 while being moderately braked by the pressing friction force of the left and right brake bodies 8, and when the thin film product a is pulled out to a desired length and pulled strongly for a moment, the thin film product is removed. The pulled out portion of a can now be cut out from the tearing perforation. At this time, the roll A is the left and right brake body 8 as described above.
Since it is braked by the pressure contact friction force, it is prevented from rotating too much due to inertia force, and there is no inconvenience such as excessive amount of thin film product a coming out.

になす。 In this way, by cutting and using the thin film product a of roll A many times, when all of the thin film product a is used up, the remaining winding core b can be used as it is on the shaft 2.
After that, the new roll A is simply inserted and set in the same manner as the previous time, so that it can be used.

ても可である。 Note that the present invention is not limited to the above-mentioned embodiments, and for example, the roll holder may be placed in a horizontal position (with the shaft 2 protruding horizontally) in addition to an upward position (with the shaft 2 vertically erected) as shown in the figure. It is also possible to install and use the support member 1 in a vertical position, in which case the shaft 2 is completely cantilevered, but there is no particular problem. In addition, if the roll A inserted and set on the shaft 2 easily comes off from the tip of the shaft 2, a cap (not shown) for preventing the roll from coming off, which has a larger diameter than the winding core B, can be attached to and removed from the tip of the shaft 2. It is also possible to fit the cap into the cap so that it can be easily removed when replacing the roll A. In addition, an auxiliary support member (not shown) is provided to face the support member 1 and removably support the distal end of the shaft 2 instead of supporting the shaft 2 in a cantilever manner, especially when the shaft 2 is placed horizontally as described above. It is also possible to open the tip of the shaft 2 by overturning the auxiliary support member when replacing the roll.

ある。 Further, in the above-described embodiment, a pair of braking mechanisms 4 are provided symmetrically, but it is also possible to provide only one of the left and right braking mechanisms. Further, the form of the brake body 8 of the brake mechanism 4 and the configuration and mounting state of the elastic member 10 that biases the brake body 8 can be variously changed. Along with this, the swing shaft 6b of the brake body may be tilted at a certain angle with respect to the shaft 2 so that the brake body can swing so as to come into contact with the shaft 2 at an angle, or the swing shaft 6b may be completely tilted toward the shaft 2. It is also possible to arrange the brake body in parallel with the axis and to be able to swing the brake body in a direction perpendicular to the axis. However, in any of these cases, it is necessary to have a roll insertion guide that extends from the part of the braking body that contacts the shaft 2 in an inclined manner toward the distal end of the shaft 2 so as to gradually move away from the shaft 2. be.

簡便なロールホルダーとなる。 Since this invention is made as described above, the braking body has a braking function that presses against the peripheral surface of the roll inserted and set on the shaft to prevent excessive rotation when cutting out the drawer accompanied by unwinding of the roll. Nevertheless, when replacing the roll on the shaft, the worker can simply push and insert a new roll onto the shaft from one end, without having to perform any operations such as opening the braking body of the braking mechanism. The roll insertion guide is pushed and the braking body is opened by the necessary amount against the elastic member, so that setting can be completed smoothly without any hindrance, making the work of changing and setting rolls very easy and efficient. This is a simple roll holder that allows you to carry out various operations.

載のロールホルダー。[Scope of Claims] 1. A support member is provided with a shaft that supports a roll formed by winding a strip-shaped thin film product around a core so that it can be inserted into and removed from the core and rotated. It has a braking body that is slidably attached to the shaft and is always urged by an elastic member to be in pressure contact with the peripheral surface of the roll that is inserted and set on the shaft to prevent rotation due to inertia during pulling, rewinding, and cutting operations of the thin film product of the roll. The roll insertion guide is provided with a braking mechanism for suppressing the above-mentioned roll insertion, and a roll insertion guide is provided on the braking body of the braking mechanism so as to be inclined in a direction that gradually moves away from the shaft as it goes toward the roll insertion end of the shaft. roll holder. 2. The roll holder according to claim 1, wherein the shaft is fixedly attached to the support member in a cantilevered manner.
