Thus the gathered part is not released during gathering to sealing so that sealing can be securely and easily performed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a roll packaging gathering device, and in particular,
This invention relates to a roll packaging gathering device that is capable of reliably positioning the original fabric when it is installed in the device, and that also enables a sealing operation with a label sticker to the gathering completed part during the gathering processing process. .

[Conventional technology]

For example, when wrapping a roll of paper, film, etc. with wrapping paper, the roll of paper, film, etc. is usually wrapped in wrapping paper that has a width sufficient for the length of the roll. The product is wrapped in a loop shape, and then finished by folding the cylindrical portions protruding from both ends of the material along the end surfaces of the material.

Conventionally, for materials having a relatively small outer diameter of about several tens of am, gathering in roll packaging has been carried out using, for example, a device as shown in FIGS. 26 and 27. In the figure, numeral 1 is the original material to be wrapped, 2 is the wrapping paper, 2a
3 is the end (cylindrical part) of the wrapping paper 2 that protrudes in a cylindrical shape from the end 1a of the raw fabric 1, and 3 is the paper that is located at the center of the raw fabric 1 to maintain the roll shape of the raw fabric 1. The tube 4 is a roller that rotatably supports the original fabric 1. As shown in FIGS. 26 and 27, the cylindrical portion 2a is rotatably provided at a hinge portion 5a on the outer circumference of the cylindrical portion 2a of the wrapping paper 2.
A plurality of claws 5, 5, .

Now, from the state shown in FIGS. 26 and 27, each of the claws 5.5,
. . are folded inside the cylindrical portion 2a as shown by the arrows in FIG. 26, to form chevron-shaped folds 6, 6, . . . as shown in FIGS. 28 and 29.

Thereafter, when the original fabric 1 with the claw 5 fixed thereon is slowly rotated on the roller 4, the folds 6 are folded (folded) along the end surface 1a of the original fabric 1 by the claw 5,
As a result, gathering is performed as shown in FIG. 30.

The raw fabric 1 that has been gathered is usually moved on a line and the gathering portion is sealed in the next process. The gathering portion is sealed by attaching a label sticker or the like to the center of the gathering portion.

[Problems to be Solved by the Invention] However, the above-mentioned conventional gathering device has the following disadvantages.

That is, the folds 6 are certainly formed by the action of the claws 5, and gathering can be performed by folding them into the end surface 1a, but when sealing the gathered portion afterwards, the original fabric 1 must be moved to the position where the next step, the sealing work, will be performed. For this reason,
During the movement, the gathering portion becomes loose. Therefore, when sealing with a label sticker or the like, the actual situation is to press the loose gathering part with, for example, a ring-shaped pressing member before pasting the label sticker.

On the other hand, as a means for preventing the gathering part from loosening during such movement between processes, when folding the formed folds 6 by relative rotation with the claws 5, the claws 5 are moved to the end surface 1a.
There is a method of strongly pressing the folds against the sides to force the folds, thereby minimizing the return (loosening) of the folds 6. However, according to such a method, the folds 6 and the claws 5 are in strong contact and rub, which not only damages the outer periphery (corner) of the gathering part, but also damages the original fabric 1 (covered part). There is also a risk of damaging the end surface 1a of the package. The outer periphery of the gathering part is formed by folding the cylindrical part 2a into a polygon, so there is a slight bulge or protrusion, and if it is pressed strongly by the claws 5, it will be easily damaged. It is easy to receive. Moreover, it is not uncommon for the product quality of a gathering to be judged by how beautiful the finish of the corners is.

Furthermore, as long as the return of the folds 6 can be prevented to some extent by strongly pressing the claw 5 against the end surface 1a as described above, the above-mentioned means are not completely ineffective.
Depending on the material of the wrapping paper 2, the above method may not work.

For example, if the wrapping paper 2 is particularly thick and has a strong stiffness, even if you press the folds strongly, it will return to its original shape immediately after the restraint is released. The same applies to Furthermore, wrapping paper 2
If it is made of polyethylene film or the like, it is highly elastic and it is difficult to even create creases.

The present invention has been made in view of the above circumstances, and allows gathering and sealing to be performed reliably in any case, regardless of the material, thickness, etc. of the wrapping paper, and moreover, to simplify the sealing work of the gathering portion. It is an object of the present invention to provide a roll packaging gathering device that can be simplified.

[Means to solve the problem]

The roll packaging gathering device according to the present invention folds the cylindrical parts protruding from both ends of the wrapping paper wound into a roll onto the original fabric inward along the end surface of the original fabric. A roll packaging gathering device configured with a paper folding mechanism for finishing, comprising a pressing member configured to be movable forward and backward with respect to the cylindrical portion and capable of coming into contact with the center portion of the end surface. Moreover, the suppressing member is characterized in that it is provided with a label holding feature for holding a label sticker to be attached to the edge.

[Effect]

After the paper folding mechanism performs gathering, the paper folding mechanism is not removed from the gathering section and remains in the state at the time of gathering, so that the gathered folds are held in the state folded into the end surface of the original fabric. becomes possible. In this state, if a label sticker is affixed to the center of the gathering part using a pressing member equipped with a label holding mechanism, the gathering part will not be released between the gathering operation and the sealing operation, ensuring the sealing operation. And it can be done easily.

Further, the pressing member can also function as a positioning mechanism when setting the original fabric to the paper folding mechanism for gathering.

When an inward folding force from 3.13, .

This internal support mechanism 50 will be described in detail below.

As shown in FIG. 1, etc., the internal support mechanism 50 is arranged in parallel with the air cylinder 40 on the movable table 41, and is made up of a tip end of a long rack rod 51 having a rack rod formed on the outer periphery. The main members are a plurality of support spokes (support members') 52, 52, . In this case, twelve support spokes 52 are provided corresponding to the number of movable pieces l3. These support spokes 52 are pin-coupled at their proximal ends, and can be opened into an umbrella shape via a link by the operation of a support spoke driving air cylinder 53. Further, the rack rod 51 is driven in the axial direction by a rod feeding device 54 provided on the movable table 41. The rod feeding device 54 is composed of a servo motor, a speed reduction mechanism, a pinion gear that meshes with the rack of the rack rod 5l, and the like. The rack rod 51 is provided so as to pass through the inside of the rod feeding device 54, and therefore, in this case, the rod feeding device 54 also has the function of holding the ranochro throat 51. An internal support mechanism 50 is constituted by the rack rod 51, the support spokes 52, the air cylinder 53 for driving the support spokes, the rod feeding device 54, and the like.

Note that the air cylinder 53 for driving the support spokes
As shown in FIG. 6, this is equipped with a biasing force holding device (biasing force holding function) 55 for keeping the outward biasing force of the support spokes 52 constant at all times. In this case, by controlling the exhaust pressure of the support spoke driving air cylinder 53, the biasing force of the air cylinder 53 is always maintained at a constant pressure (3.5 kg/cm' in this embodiment). It has become.

Further, as shown in the figure, the rod feeding device 54 is electrically connected to the servo motor 19 for driving the moving piece l3 via a control means 56, and is connected to the servo motor 19 for driving the moving piece l3. It is configured so that the return operation (movement from the left to the right in the figure) can be controlled based on the movement of the moving piece l3. Further, in this case, the biasing force retaining device 55 is also configured to have its operation controlled based on a signal from the control means 56.

Next, the operation of the roll packaging gathering device 9 constructed as described above will be explained with reference mainly to FIGS. 7 to 25.

First, as shown in FIG. 1, move the moving table 41 so that the pressing member 1l provided at the tip of the telescopic rod 40b of the air cylinder 40 on the moving table 4l faces the opening 12a of the support disk l2. move. Then, as shown in FIG. 7, the telescopic rod 40b of the air cylinder 40 is extended. The telescopic rod 40b protrudes to the front side of the support disk 12 through the opening 12a of the support disk 12, and the suppression plate 1l provided at the tip thereof is connected to the movable pieces 13, 13 . It is stopped and fixed at a position slightly protruding from the front end surface of... Also, at this time, each moving piece 13, 13. . . are all located on the outer peripheral side of the support disk 12, as shown in FIG.

(2) Place the original fabric 1 to be gathered on the receiving plate 6l of the mounting table 60. In this example, it is assumed that the original fabric 1 has a diameter of approximately 5001III1, and that the wrapping paper 2 has already been wound around the original fabric 1 into a roll.

The mounting table 60 is moved rearward to be spaced apart from the support disk 12 before the original fabric l is placed thereon. Once the original fabric 1 is placed on the receiving plate 6l, the entire mounting table 60 is moved to the gathering device ll side. The mounting table 60 stops after moving to a certain extent, so when the mounting table 60 stops,
Next, when the original fabric 1 is pressed forward toward the support disk 12, the front end surface 1B of the original fabric 1 comes into contact with the pressing member 1l protruding from the opening 12a of the support disk 12 and stops. The position where the end surface 1a abuts against the pressing member 11 is slightly in front of the front end surface of the moving piece l3. That is, this positions the original fabric 1 with respect to the paper folding mechanism 10. At this time, the cylindrical portion 2a of the wrapping paper 2 protruding from the end surface 1a is moved by each moving piece 13, 13,
The inner edge 23a of ... is inserted into the inside of the circle to be formed. The movement of the original fabric 1 on the receiving plate 6l is performed using the receiving plate 61.
Since the transfer bodies 62, 62, . . . are attached to the transfer bodies 62, 62, . . .

■ Once the above condition is reached, hold the original fabric l in that position.

In this case, as shown in FIG. 9, the mounting table 60 and the frame 65 supporting the gathering device 9 are
As mentioned above, the original web holding means 66 for holding the original web 1 placed on the receiving plate 6l is provided, and the original web 1 is supported at three points by these original web pressing means 66.

■ Once the original fabric l has been positioned and fixed as described above, the telescopic rod 40 of the air cylinder 40 equipped with the pressing plate 11
b is retracted, and then, as shown in FIG. 10, the movable table 4l is horizontally moved in the direction of the arrow in the figure, so that the internal support mechanism 50 faces the opening l2a of the support disk l2.

■ As shown in FIG. 11, by driving the rod feeding device 54 of the internal support mechanism 50, the rack rod 5
1, and insert the tips of the support spokes 52, 52, . (omitted in the figure), and
Open the support spokes of the book 5 2.5 2,... into an umbrella shape.

The tip of each support spoke 52 opened as described above. The wrapping paper 2 comes into contact with the inner peripheral surface of the cylindrical part 2a, and the cylindrical part 2
A is stretched from the inside, and the cylindrical portion 2a changes from a cylindrical shape to a substantially regular dodecagonal shape (see FIG. 12). When this state is reached, the biasing force retaining device 55 operates to keep the biasing force of each support spoke 52 constant (3.5 kg/c1 in this case).

■ If the above condition occurs, each support spoke 52
is maintained in the above state, and by operating the servo motor 19, the moving pieces 13, 13, . . . are moved inward all at once as shown in FIG. 13. Ru.

Here, since each support spoke 52 is located between each movable piece 13 as shown in FIG. It becomes something that moves.

At this time, as the movable piece 13 moves inside the end surface 1a, the portion (crest B) that is stretched by the support spokes 52 also falls down so as to be gradually drawn inward. Furthermore, the support spokes 52 move backward as the movable piece 13 moves inward (the first
(See Figures 3 and 15).

゛At this time, in this embodiment, the support spoke 52
is equipped with a biasing force retaining function (biasing force retaining device 55) that keeps the biasing force that pushes the tubular portion 2a outward at all times, so that the peak of the tubular portion 2a whose diameter is gradually reduced is Part B
This results in an always constant force (in this case 3.5
kg/am"). Furthermore, in this embodiment, as described above, the control means 56 controls the withdrawal of the support spokes 52 based on the inward movement of the movable piece l3. , in this case, the support spoke 52 starts to retreat at the same time as the servo motor l9 is activated,
Assuming that the time it takes for the movable piece l3 to change from the outermost position of the support disk 12 to the innermost position is T seconds, the support spoke 52 is moved when (T - α) seconds have passed. Controlled to close instantly (No. 16
figure). In this way, if the closing operation of the support spoke 52 and the subsequent withdrawal operation are slightly earlier than the point at which the inward movement of the moving piece l3 is completed, the valley of the fold that is folded inward by the moving piece l3 can be removed. Interference between A and the support spoke 52 can be reliably prevented.

(2) When the movable pieces t a, t a, . Then, due to the movement of the movable pieces 13 inward of the support circle tlljl2, the portion of the cylindrical portion 2a of the wrapping paper 2 where the inner edges 23a of the movable pieces 13 are in contact is pushed inward. As a result, the movable pieces 13, 13 . A trough A formed by being pushed inward by ... and a peak B which attempts to maintain the cylindrical shape, that is, a portion between each moving piece 13, are formed, and folds 6 are formed. Moreover, since the springing member 24 moves along the end surface 1a of the original fabric 1, the valley portion A of the fold 6 is almost pressed against the end surface 1a by the moving piece l3.

■ If the above condition occurs, the air cylinder 26
The two spring-out members 24 and 24 provided on each moving piece l3 are supplied with compressed air through the opening/closing mechanism 27.
Open it in a V-shape as shown in FIG. At this time, the opening angle formed by both springing members 24, 24 is set to 30°. Then, by opening all the pop-up members 24,24 of the twelve moving pieces 13 in a V-shape, as shown in FIG. They become parallel and almost close to each other. Since a triangular fold 6 is formed between each movable piece 13, the above operation causes this fold 6 to be sandwiched between adjacent open spring-out members 24,
The triangular shape is crushed to create a perfectly creased shape (see Figures 19, 20, and 21).

■ Once the above condition is reached, all that is left is to move the moving pieces l3.
While maintaining the above state, the motor 36 is operated to rotate the entire support disk 12 via the drive gear 37 and center gear 35.

When the support disk 12 is rotated, the 12 folds 6 formed with the rotation move into the movable piece 13 (springing member 24
) to the end surface 1a of the original fabric 1, and the gathering is completed as shown in FIG. 22. The rotation direction of the support disk 12 at this time is determined in consideration of the offset direction of the shaped folds 6, and the fold line C formed when the folds 6 are folded toward the end surface 1a side is radially directed. Rotate it so that it points towards the center. Note that when rotating the support disk l2, each moving piece 13, 13 . ... is rotated with the gap between the protruding members 32 which are placed close to each other being slightly widened by slightly returning to the outer circumferential direction, the folding of the fold 6 into the edge 1a is extremely smooth. done to. Furthermore, due to the rotation of the support disk 12 (moving piece 13), the original web 1 will also receive a certain degree of rotational force.
Since the original fabric 1 is held by the original fabric holding means 66, 66, 66, the original fabric 1 does not rotate on the receiving plate 61 during the gathering process.

[Phase] Once the gathering has been performed as described above, as shown in FIG. The press plate 11 is moved in the direction of the arrow in the figure to again face the opening 12a of the support disk l2.

■ On the other hand, during the steps from ■ to ■ above, the pressing plate 1
A label sticker L is attached to the front end surface of 1.

To do this, the vacuum device 44 is activated, and the tube 43 is
Air is sucked through the suction cup 42 provided on the pressing plate 2, and the label sticker L is applied thereto. The label seal L is held by the suction cup 42 of the pressing plate 11 by suction. Although not shown in the drawings, in this embodiment, a label seal supplying device storing a large number of the label stickers L is installed in the vicinity of the gathering device 9, and the label sticker supplying device automatically moves the pressing plate 11 The structure is such that the label sticker L is supplied to the container.

Therefore, as shown in FIG.
At the time when the label sticker L is opposed to the opening 12a, the label sticker L is already held by the pressing plate 11.

@Expansion and contraction as shown in Figure 24. One rod 40b is extended, and the label seal L is held by the pressing plate 1l by vacuum action.
is pressed and attached to the end surface 1a on which gathering has been completed. Thereafter, when the suction operation by the vacuum device 44 is stopped and the telescopic rod 40b is withdrawn, the label sticker L that has been suctioned and held by the suction cup 42 is affixed to the center of the gathering section.

Gather. After the ring portion is sealed, as shown in FIG. 25, the movable piece l3 is moved back to the initial position, that is, the outermost position of the support disk 12, and the pop-out member 32, which has been opened in a V-shape, is removed. Just close it.

[Co., Ltd.] With the above, gathering of one end surface 1a of the original fabric 1 is completed. When gathering the other end surface 1a of the web 1, after releasing the restraint of the web l by the web pressing means 66, the mounting table 60 is moved back, and then the receiving plate 61
After rotating the support plate 63 to rotate the original fabric 1 by 180°, the same operations as ① to ① above may be performed.

As described above, according to the gathering device 9, the folds 6, 6, . Since the gathering part can be sealed, the gathering part will not be released between the completion of gathering and the sealing operation, and the folded folds 6 will never loosen. Therefore, it is not necessary to perform work such as reconstraining the folds with a presser member such as a ring at the sealing position before the sealing work as in the past, and even if the wrapping paper 2 Even if the material is difficult or impossible to form, it can be reliably and easily sealed.

Furthermore, since the sealing work of the gathering part is carried out at the same position without moving from the gathering process position, there is no movement of the original fabric 1 from the completion of gathering to the sealing work, and movement between processes is eliminated. As a result, work efficiency can be improved and the line can be shortened.

Furthermore, according to the present gathering device 9, as described above, since the gathering portion is not released before the gathering portion is sealed, the folds of the folds 6 are formed in order to prevent the folds 6 from returning (loosening). There is no need to press the moving piece 13 unnecessarily strongly, and there is no damage to the gathering part end (peripheral end) and the end surface 1a of the raw fabric l, which are particularly important in ensuring the quality of the gathering.

Moreover, it is a pressing member! 1 is the raw material 1 at the gathering position.
．． Since the pressing member 11 is in contact with the central part of the end surface of the material, as in this embodiment, the pressing member 11 is pressed against the raw material l by the gathering device 9.
It can also function as a positioning device when setting. When the above-mentioned gathering devices are installed on both sides of the line to fully automate the gathering of both end faces of the web 1, the web 1 is usually positioned in advance by a center position, etc. However, in the so-called semi-automatic type in which the positioning of the original fabric 1 is performed for each original fabric as in the above example, the positioning function by the pressing member 11 is extremely effective. Therefore, when incorporating the gathering device 9 according to this embodiment into a fully automated line,
The positioning operation shown in (2) above may be omitted. Of course,
Conversely, the label holding function constituted by the suction cup 42, the vacuum device 44, etc. may not be operated, and only the positioning function may be utilized.

In the embodiment, the pressing member l1 is actuated by the air cylinder 40, but the means for driving the pressing member 1l according to the present invention is not limited to the air cylinder, and other structures may be used. It may be. For example, in the above example, the pressing member 1l is located on the central axis of the web 1 and moves forward and backward on a linear trajectory with respect to the end surface la. It may also be configured such that it moves forward and backward with respect to the end surface la while drawing an arcuate trajectory through a link mechanism or the like.

In addition, in the embodiment, the present gathering device 9 has been shown to have an internal support mechanism 50, but the present invention does not necessarily have to include the internal support mechanism 50, and the gathering device 9 does not necessarily have to be equipped with the internal support mechanism 50. Alternatively, a conventional device as shown in FIGS. 26 and 27 may be used. The same applies to the moving piece 13 and the like. However, according to the gathering device 9 of this embodiment, due to the functions of the moving piece 13 and the support mechanism 50, which are unique to the gathering device 9, the gathering itself can be finished with an extremely high quality compared to the conventional device. be able to.

〔Effect of the invention〕

As explained above, according to the gathering device of the present invention, the gathering part can be sealed while the folds folded into the end face of the original fabric by gathering are held by the movable piece, so that from the completion of gathering to the sealing operation. During this process, the gathering part is never released and the folded folds are never loosened. therefore,
Not only is it not necessary to perform work such as restraining the folds again using a holding member such as a ring at the sealing position before the sealing work as in the past, but it is also possible to eliminate the need to restrain the folds using a holding member such as a ring before the sealing work. Even if the sealing is difficult or impossible, sealing can be performed reliably and easily.

Furthermore, in order to carry out the sealing work of the gathering part at the same position without moving from the gathering process position,
There is no movement of the original fabric from the completion of gathering to the sealing operation, and movement between processes is eliminated, thereby improving work efficiency and shortening the line.

Furthermore, since the gathering part is not released before it is sealed, there is no need to press the folds of the folds unnecessarily strongly with the movable piece to prevent the folds from returning (loosening). There is no damage to the ends (peripheral ends) of the gathering part, which is particularly important in ensuring the quality of the gathering.

In addition, since the pressing member comes into contact with the center of the end surface of the original fabric at the gathering position, the pressing member functions as a positioning device when setting the original fabric in the gathering device as in this embodiment. It can also bring about various excellent effects, such as:
