BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a turn table apparatus of a roll body for mounting and fixing a roll body in which paper such as a roll label and various tapes made of resin are wound in a cylindrical shape.

For example, the roll labeling machine shown in FIG. 7 is equipped with the turntable apparatus b for mounting roll label a.

In general, the turntable device b includes a mounting table c on which a roll label a is mounted, and rotates about a vertical axis, and a holder shaft d for positioning positioned protruding from the center of the mounting table c. In the operation of dropping the roll label a directly above the mounting table c, a core tube (herein, a paper tube) in the center of the roll label a is fitted into the holder shaft d.

In the case of the labeling machine, since the tape is drawn out at high speed, it is necessary to fix it firmly. If there is a shake between the core of the roll label a and the holder shaft d, the stability of the continuous supply of the roll label a can be ensured. none.

Here, in order to eliminate the shake between the core pipe of the roll label a and the holder shaft d, conventionally, the following two methods are dealt with.

One of them is a method of fixing a key by inserting a wedge-shaped key between the core pipe of the roll label a and the holder shaft d.

The other is a method of fastening and fixing the roll label a by attaching a cover (not shown) to the holder shaft d with a screw.

The conventional mounting technology of the roll body has the following problems.

(1) The outer diameter of the holder shaft d is set to correspond to the inner diameter of the core pipe of the roll label a.

Therefore, when roll label a is set and mounted by dropping roll label a directly on the mounting table c, if a core of the roll label a is inclined even a little or both centers are displaced, a core pipe will contact the edge part of holder axis d. Or when it is inserted, friction resistance increases between the core pipe and the holder shaft d, and smooth mounting is not performed.

(2) Both of the above fixing methods require a fixing operation such as the insertion of a key or the screwing of a cover after the operation of mounting the roll label a on the mounting table c.

Since this fixing work is performed manually by the operator, the fixing work of the roll label takes more time and labor.

(3) When the roll label a is replaced, a new release operation of the core pipe, in which the key is taken out or the screw is reversed and the cover is removed, is newly added.

Therefore, when replacing with a new roll label a, a number of work processes such as the fixing operation of the core pipe, the loading operation of the roll label a, and the fixing operation must be performed. There is a problem that requires a lot of time and effort.

(4) As shown in Fig. 7, in order to automate the labeling machine, the label supply means is arranged in two systems, and when the remaining amount of one roll label a reaches the set amount, the label supply means of the other system is provided. It is possible to supply the tape for labeling continuously.

At present, however, no proposal for a suitable technique for automating the fixing of roll label a has been made.

For this reason, since the fixing of the roll label a is relied on manually as mentioned above, the full automation of a labeling machine is hindered.

The present invention has been made in view of the above disadvantages, and an object thereof is to provide a turntable device for the following roll body.

(1) The simple structure enables mounting and fixing of the roll body at the same time, thus making it possible to greatly increase one's hand.

(2) The roll body has excellent setability and exchangeability.

(3) Promote full automation of machines equipped with roll bodies.

The 1st invention of this application is the turntable apparatus which has the support shaft located coaxially with the center hole of the roll body which wound the tape at least continuously, and pulls out a tape from the roll body which rotates about the support shaft, The said support A holder device for positioning is provided at the tip of the shaft, and the holder device is provided with a plurality of rotating bodies so as to be in contact with the inner circumferential surface of the central hole of the roll body.

According to a second aspect of the present invention, in the first aspect of the invention, a mounting table for supporting a roll body is added and mounted, and a support shaft is positioned at the center of the mounting table.

3rd invention of this application is the turntable apparatus of the roll body in the said 1st invention or 2nd invention that the largest diameter of the said holder apparatus is equal to or slightly larger than the inner diameter of the center hole of a roll body.

According to a fourth aspect of the present application, in the first or second aspect of the invention, the rotating body of the holder device is arranged to allow rotation of the roll body in the insertion direction only and to restrict rotation of the roll body in the rotational direction. It is a turn table device of a roll body, characterized in that.

5th invention of this application is a turn table apparatus of the roll body characterized by the above-mentioned 1st invention or 2nd invention, The said roll body is a label roll for labeling which wound the label tape.

The present invention achieves at least one of the following effects.

(1) A simple structure in which a holder device constituted by arranging a plurality of rotating bodies is arranged at the tip of the support shaft, and the mounting and fixing of the roll body can be performed simultaneously by a simple operation of simply inserting the roll body 10. It is possible to do this, and the conventional fixing work by the manual labor of an operator who installs and removes a key or a cover can be omitted.

(2) Since the fixing work of the roll body can be omitted, the setability and exchangeability of the roll body are excellent.

(3) Since the set (mounting and fixing) of the roll body can be completed only by positioning the roll body, it is possible to promote the complete automation of various machines using the roll body.

(4) Since the outer surface of the rotating body attached to the holder device exhibits an arc shape, even if the roll body is slightly inclined or slightly displaced from the center of the center hole of the roll body, the roll body is guided by the guide action of the rotating body. It is possible to guide and reliably insert the holder device into the center hole of the.

(5) The rotating body of the holder device is rotatably provided, and the rotating body rotates when the roll body is set, and large frictional resistance is not generated at the joint portion.

Therefore, the set work of a roll body can be performed smoothly.

(6) The maximum diameter of the holder device provided in the upper part of the support shaft is formed to be equal to or slightly larger than the inner diameter of the center hole of the roll body. Therefore, the frictional resistance (fixing force) with respect to the rotation direction of a roll body increases, and it is possible to fix a roll body strongly.

Therefore, either high speed rotation or intermittent rotation can be responded, and it is possible to take out a tape stably from a roll body.

EMBODIMENT OF THE INVENTION Hereinafter, one Embodiment of this invention is described, referring drawings.

(1) roll body

1 and 2 show an example of the turn table device 20 according to the present invention.

In FIG. 1, the roll body 10 winds the tape 12 which has a predetermined | prescribed electric field on the outer periphery of the core pipe 11, and it draws out the starting end of the tape 12, and serves for various uses.

The core pipe 11 is a cylinder made of paper, resin, or metal, and the inner diameter D of the center hole is set to an appropriate diameter according to the use of the roll body 10.

The inner circumferential surface of the core pipe 11 may be formed as a smooth surface, and a plurality of grooves may be formed along the axial direction.

The tape 12 is formed of various materials, and is a label sheet or a tag label subjected to a printing process.

(2) turntable device

The turn table device 20 is a device for mounting the roll body 10 and for extracting a tape from the roll body 10. The turn table device 20 mounts the roll body 10 and rotates about the support shaft 21. The table 22, the support shaft 21 provided in the center of the mounting table 22, and the holder apparatus 30 for positioning attached to the front-end | tip part of the support shaft 21 are provided.

The support shaft 21 which penetrates through the mounting table 22 rotates integrally with the mounting table 22, and also the holder device 30 attached to the front-end | tip of the support shaft 21 also supports the support shaft 21. Rotate integrally with

The support shaft 21 may be of any type, such as an idle type that only supports the bearing through the number of shafts, and a rotation drive type that rotates in response to a drive of a motor or the like.

(3) holder device

The holder apparatus 30 is comprised from the main body 31 fixed to the support shaft 21, and the some rotating body 32 provided in the side surface of the main body 31. As shown in FIG.

The main body 31 is a support member for supporting the plurality of rotating bodies 32 at a position equally spaced from the center (rotational center) of the support shaft 21, and is a bolt at the distal end of the support shaft 21. And nuts 33 and the like are fixed integrally.

Although the case where the main body 31 is a rectangle in this embodiment is shown, if the main body 31 is a dimension which can be interpolated to the core pipe 11 of the roll body 10, there is no restriction | limiting in the shape of the main body 31. As shown in FIG.

On the pair of side surfaces of the main body 31 facing each other, a total of four orbital rotating bodies 32 are provided, and the plurality of rotating bodies 32 are connected to the core pipe 11 of the roll body 10. By press-contacting the inner circumferential surface thereof, the roll body 10 can be fixed to the holder device 30.

Each rotating body 32 is rotatably mounted about the installation shaft 34 in the direction orthogonal to the support shaft 21.

A bearing with little shaking is applied to the rotating body 32, and it is attached to the installation shaft 34 by the stop ring 35, such as a "C" ring.

In addition, the rotational direction of the rotating body 32 allows rotation of the roll body 10 only in the insertion direction, and restrains the rotation of the roll body 10 in the rotational direction.

In the case of the present embodiment, the relationship between the four rotors 32, L is the distance to the outermost end of the pair of rotors 32, 32 located at the diagonal of the support shaft 21, L The distance L to the outermost end of the pair of rotating bodies 32 and 32 is set equal to or slightly larger than the inner diameter D of the center hole of the core pipe 11 constituting the roll body 10 (D≤L). Is critical.

In other words, the distance L / 2 from the center of the support shaft 21 to the outermost ends of the respective rotors 32 and 32 is equal to or slightly larger than the radius d of the center hole of the core pipe 11 ( d≤L / 2).

Setting the dimensional conditions of the rotating body 32 relative to the diameter of the core pipe 11 as described above is such that the plurality of rotating bodies 32 are pressed against the inner circumferential surface of the core pipe 11 of the roll body 10 to roll the body. This is because the holder 10 is fixed to the holder device 30.

Therefore, the pressure which the rotation body 32 presses against the inner peripheral surface of the core pipe 11 of the roll body 10 will increase as this dimension difference becomes large.

Moreover, the use of the rotating body 32 whose outer peripheral surface is arc-shaped for fixing the core pipe 11 is for making it easy to insert the holder apparatus 30 in the inside of the core pipe 11.

(4) How to set the roll body

Next, the set method of the roll body 10 is demonstrated.

The state immediately before setting the roll body 10 to the turntable apparatus 20 is shown in FIG. 3, and the state after setting the roll body 10 is shown in FIG.

Furthermore, in order to make understanding easy, in FIG. 3, 4, the pair of rotating bodies 32 with which the holder apparatus 30 provided in the diagonal of the support shaft 21 is shown on the same plane, is demonstrated. do.

As shown in FIG. 3, the roll body 10 is slowly moved with the roll body 10 positioned directly above the mounting table 22 such that the support shaft 21 and the core pipe 11 are positioned substantially in the same vertical position. By simply dropping, it is possible to simultaneously mount and fix the roll body 10.

This will be described in detail.

As mentioned above, the outer surface of the rotating body 32 provided in the side of the holder apparatus 30 has shown the arc shape.

Therefore, when the holder device 30 is inserted into the center hole of the core pipe 11, the outer surface of the rotating body 32 showing the arc shape of the holder device 30 and the inner circumferential surface of the core pipe 11 do not contact. The gap is secured between both surfaces. By the presence of this gap, even if the roll body 10 is slightly inclined or slightly shifted from the center, the holder device 30 can be smoothly inserted into the core pipe 11.

As mentioned above, the largest diameter which passes through the outermost end of the rotating body of the holder apparatus 30 provided in the upper part of the support shaft 21 is equal to or slightly larger than the inner diameter of the center hole of the core pipe 11. .

Therefore, if the roll body 10 is further dropped, the inner circumferential surface of the core pipe 11 is in contact with the outer surface of the plurality of rotating bodies 32, and the core pipe 11 is in contact with the rotating body 32 at the plurality of points. do.

If there is a difference in dimension between the maximum diameter of the holder device 30 and the diameter of the core pipe 11, as shown in enlarged view in FIG. 2, the edge portion of the main surface of the rotating body 32 is eaten into the inner circumferential surface of the core pipe 11 (deformation). Press). Therefore, the frictional resistance (fixing force) with respect to the rotation direction of the roll body 10 will increase.

That is, the rotating body 32 is not a large resistance element with respect to the falling direction of the roll body 10, but is a large resistance element with respect to the rotation direction of the roll body 10.

Moreover, since the rotating body 32 revolves, while the roll body 10 is dropped until the lower surface of the roll body 10 is installed in the mounting table 22, the core pipe 11 and the rotating body Large frictional resistance does not occur between the main surfaces of (32).

Therefore, it is possible to smoothly insert the roll body 10 apart.

Thus, not only the mounting of the roll body 10 but also the fixing operation by only dropping the core pipe 11 of the roll body 10 to the holder device 30 installed on the upper part of the support shaft 12. It is also possible to carry out simultaneously, and the conventional fixing work by the manual labor of the operator who installs and removes the key or the cover is unnecessary.

After the mounting of the roll body 10 and the setting of the fixing are completed, the tape is taken out from the roll body 10 in the same manner as in the related art and used for use according to the application.

During the rotation of the roll body 10, since a large frictional resistance is generated between the core pipe 11 and the main surface of the rotating body 32, slippage in the rotational direction is unlikely to occur between the core pipe 11 and the holder device 30. It can be fixed strongly.

Moreover, since several places of the core pipe 11 are pressed by the rotating body 32, there is no possibility that the roll body 10 may shake during rotation.

In addition, when replacing the roll body 10, only the core pipe 11 remaining in the holder device 30 of the turntable device 20 is removed, and the new roll body 10 is loaded and replaced as described above. It is good to work.

Thus, when the roll body 10 is for example a roll label shown in FIG. 7, it is possible to automate the set work of the roll body 10 and to enable full automation of the labeling machine.
