[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically bundling a plurality of stacked articles by using a heat-sealable film.

[0002]

2. Description of the Related Art Many conventional bundling devices of this type have been proposed. For example, as disclosed in JP-B-51-33038, a plurality of articles are bundled together by a film. There is something like this. By the way, in such a bundling device, after enclosing a plurality of articles, back tension is applied to the film to fasten the articles, and in the tightened state, the joined portion of the film is heat-sealed, and then the heat-sealed portion is cut. It is supposed to do.

[0003]

By the way, in such a conventional device for bundling articles, it is common to apply back tension to the film surrounding the article mechanically using a step roller. Is. However, when the article is elastic and slippery, such as a tablet or a capsule-shaped drug packaging sheet, when the articles are bundled in a laminated state, the back tension of the step roller is reduced. The adjustment of the applied force becomes extremely difficult, and the bundled articles may fall off in the middle due to insufficient tightening.

Further, when the back tension is applied by using the step roller, the amount of the film fed out becomes constant, so that it becomes impossible to bundle the articles having different sizes, and the tolerance for the different articles becomes unacceptable. There was a problem of disappearing.

The present invention has been made in view of such conventional problems, and a first object thereof is to provide a film suitable for a film that wraps around the outer periphery of an article to be bundled regardless of the elastic force of the article. An object of the present invention is to provide a method and apparatus for gripping an article that can be bundled while tightening the article by applying back tension and can secure a large allowance for the size of the article to be bundled.

A second object of the present invention is, in addition to the above-mentioned first object, the size of an article for which the amount of payout is to be bundled without excessively paying out the film when the film goes around. An object of the present invention is to provide a device for bundling articles that can be automatically adjusted to an appropriate length according to the size.

[0007]

In order to achieve the first object, in the method for bundling articles according to claim 1 of the present invention, the film fed from the original portion is made to intersect the transportation path of the articles. The plurality of articles stacked and placed on the transfer path while transferring from the front of the intersection to the rear, the film wraps around the outside of the article, and the bonded portion of the wrapping film is bonded. In the method of bundling articles, the feeding means for feeding the film from the original portion and feeding it to the intersecting portion is driven by a motor capable of forward and reverse rotation, and the motor is used when the film is rotated. Is rotated in the normal direction, and the motor is rotated in the reverse direction after revolving to rewind the film to a predetermined torque, and the film is bonded in a state where tension is applied.

In order to achieve the above first object,
In the article bundling apparatus according to the second aspect of the present invention, there are provided a film which is unwound from the original fabric portion and arranged so as to intersect with the article transfer path, and a plurality of films are stacked and placed on the transfer path. Transporting means for transporting the article from the front of the intersection to the rear and intermittently transporting the film around the outer circumference of the article, and a bundling means for adhering and cutting a joint portion of the circulated film, A feeding means having a motor capable of rotating in the forward and reverse directions to feed a film from the original film portion, and a forward rotation of the motor in the feeding direction when the film is rotated around an article, and a predetermined tension on the film after the circulation. Drive control means for reversing the motor to a predetermined torque in order to add.

Further, in order to achieve the first object,

It is characterized by driving.

In order to achieve the above second object,
According to a fourth aspect of the present invention, there is provided the article bundling apparatus as recited in the second aspect, wherein the drive control means is provided each time the film tension downstream of the feeding means becomes equal to or more than a set value when the motor is normally rotated. The feature is that the motor is driven in the forward direction little by little.

[0011]

In the method for bundling articles according to the first aspect of the present invention, the film wound around the raw material portion is fed out by the forward rotation of the motor and is sent to the intersection portion with the transfer path. An article transferred from the front to the rear of the intersecting portion comes into contact with and is drawn rearward, and the unwound film is wound around the outside of the article and circulated. Then, after the film is circulated to the outside of the article in this way, the motor is reversely controlled to a predetermined torque to apply a predetermined back tension to the film to tighten the article, and in this tightened state, the joined portion of the film is Glue and cut. At this time, since the back tension is applied to the film by the reverse rotation control of the motor, the tension value of the back tension can be arbitrarily set regardless of the elasticity of the articles to be bundled. Therefore, the tightening force when bundling the articles with the film can be set in an optimum state to prevent the articles from falling off. Further, the amount of the film fed out can be arbitrarily set by the forward rotation of the motor, and the excessively fed out amount can be returned by the reverse rotation.
A large tolerance for the size of the articles to be bundled can be secured.

Further, in the article bundling apparatus according to the second aspect of the present invention, the article placed in front of the intersection on the transfer path is intermittently transferred to the rear of the intersection by the transfer means.

At this time, the motor of the feeding means is normally rotated by the drive control means, and the film is fed from the original portion. When the film is rotated, the motor is reversely driven to a predetermined torque by the drive control means to rewind the film, and a predetermined tension due to the back tension is applied to the film in the winding portion. The bundling means bonds the joining portions of the films in a state where the tension is applied to clamp the articles, and then the adhesive portions are cut to bundle the articles. At this time, since the back tension is applied to the film by the reverse rotation control of the motor, the tension value of the back tension can be arbitrarily set regardless of the elasticity of the articles to be bundled. Therefore,
The tightening force for bundling the articles with the film can be set in an optimum state to prevent the articles from falling off. Furthermore,
The amount of the film fed out can be arbitrarily set by the normal rotation of the motor, and the excessive amount of the film fed out can be returned by the reverse rotation, so that a large allowance for the size of the article to be bundled can be secured.

Since the above film is put out early, the film can be smoothly wrapped around the outer circumference of the article.

According to a fourth aspect of the present invention, there is provided an article bundling apparatus in which an article placed in front of the intersection on the transfer path is intermittently transferred to the rear of the intersection by the transfer means. . Then, the film is drawn backward by the article transferred to the rear side, whereby the film is wrapped around the outer periphery of the article and circulates. At this time, as the film is drawn backward, the film tension on the downstream side of the feeding means increases, and each time the tension reaches a set value, the drive control means gradually rotates the motor of the feeding means in the forward direction. The control of making the film repeat is repeated, and the film is gradually fed out from the original fabric portion. For this reason, the film is gradually fed out from the original portion in accordance with the amount of pulling back, and is automatically adjusted to an appropriate feeding amount for the size of the article to be bundled. Becomes
It is possible to prevent the film from being unwound excessively during the orbit.

[0015]

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. 1 to 3 show an embodiment of a device 10 for bundling articles according to the present invention, FIG. 1 is a schematic view showing the overall structure, FIG. 2 is a plan view of a main part of a transfer section, and FIG. It is a time chart which shows the operation relation of each component.

The bundling device 10 is provided with an original fabric portion 14 around which a flexible and heat-fusible film 12 is wound, and the film 12 delivered from the original fabric portion 14 is a feed roller of a delivery means. 16 and intermediate roller 18, lifting roller 2
After circling around 0, the article is guided by the bundling portion 22 on the transfer path 25 of the article and disposed so as to intersect with the transfer path 25.

To the bundling portion 22, a transfer means 26 for intermittently transferring a plurality of articles 24 stacked and placed on the transfer path 25, and a joint portion of the film 12 circulated outside the articles 24 are bonded. There is provided a bundling means 28 for cutting after that, and the bundling means 28 is provided with a heat-sealing mechanism part 29 including an upper sealer 29a and a lower sealer 29b, and a cutter 30.
and a cutting mechanism section 30 provided with a.

The feed roller 16 of the feeding means comprises a main roller 16a and a sub roller 16b which is pressed against the main roller 16a with a predetermined pressing force. The film 12 is placed between the main roller 16a and the sub roller 16b. It is pinched. This main roller 16a
Is driven to rotate by a servomotor 32 capable of rotating in the normal and reverse directions. The servomotor 32 is controlled to rotate in the forward direction or the reverse direction by the drive control means 33 to rotate the main roller 16a in the X direction or the Y direction. The film 12 is normally or reversely fed.

In this embodiment, the servo motor 32 is driven by the drive control means 33 under torque control. That is, the drive control means 33 repeats the control of driving the motor 32 little by little in the forward direction and stopping it every time the film tension on the downstream side of the roller 16 of the feeding means becomes equal to or more than the set value T1 during the forward rotation. Raw part 1
The film 12 is fed from 4 at a time. That is, the drive control unit 33 has a braking force generation unit that restrains the rotation of the motor 32 and a rotation detection unit that detects that the motor 32 is rotated against the braking force generated by this generation unit. At the time of normal rotation, first, the brake force generating portion generates a brake force capable of restraining the rotation of the motor 32 up to a torque corresponding to the set value T1 of the film tension, and the rotation of the motor 32 is stopped so that the film tension is When the set value T1 is reached and the torque due to this tension causes the motor 32 to rotate against the braking force,
This is detected by the rotation detector, and each time the rotation is detected, the motor 3 is moved for a predetermined short time or a predetermined rotation angle.
2 is normally driven. Further, at the time of reverse rotation, the motor 32 is reversely driven to a predetermined torque at which the film tension of the revolving portion reaches a set value T2 and then stopped.

It should be noted that the braking force generating section can be constructed by preventing a rotating magnetic field from being generated when electric power is supplied to the motor 32, and the braking force at this time can be arbitrarily adjusted by the strength of the electric power supplied. . Alternatively, the braking force generator turns the friction brake mechanism on and off with an electromagnetic clutch.
It can also be configured to actuate.

On the other hand, as shown in FIG. 2, the transfer path 25 is formed by a pair of slide plates 25a, 25a separated in the width direction of the article 24 at appropriate intervals.
Inside the 5a and 25a, a pair of fingers 34 and 34 that constitute the transfer means 26 are arranged to face each other. A plurality of the fingers 34, 34 are arranged in the transfer path 25 at equal intervals in the flow direction of the article 24, and the lower ends of the fingers 34, 34 are attached to a chain 40 that is wound around a sprocket 38 driven by a motor 36. It is attached and moved from left to right in FIG.

The upper and lower sealers 29a and 29b constituting the heat-sealing mechanism portion 29 of the bundling means 28 have the transfer path 25.
The upper and lower sealers 29 are arranged so as to face each other with a seal between them.
The opposing portions of a and 29b are heated to the optimum temperature for heat-sealing the film 12. Further, a storage portion 29c of the cutter 30a of the cutting mechanism portion 30 is formed in a central portion in the thickness direction of the lower sealer 29b, and the cutter 3 is stored in the storage portion 29c.
0a is stored so as to be vertically movable. The upper and lower sealers 29a and 29b are the pair of sliding plates 25 of the transfer path 25.
The width is set so that it can be inserted into the separated portions of a and 25a. Further, the elevating roller 20 is attached to the upper sealer 29a, and the upper sealer 29a and the elevating roller 20 are integrally moved up and down. Further, on the right side in FIG. 1 of the upper sealer 29a, a gate-shaped stopper 42 whose lower part in the central portion is notched so that the film 12 can be inserted is attached so as to be vertically movable. Here, the upper and lower sealers 29a, 2
9b, the cutter 30a, and the gate-shaped stopper 42 are independently driven by a cylinder device (not shown).

The film 12 passes in front of the heat-sealing mechanism 28 in the bundle 22 and is inserted between the slide plates 25a and 25a so as to intersect the transfer path 25, and then the clamp portion 44 and the fixing portion. It is wound around the roller 46 and the step roller 48 and wound around the scrap winding unit 50. The clamp portion 44 includes a clamp pin 44a horizontally moved by the cylinder device 52 and a receiving portion 44b attached to the frame of the bundling device 10. The clamp pin 44a is pressed by a recess 44c formed in the receiving portion 44b. As a result, the film 12 is fixed between the clamp pin 44a and the receiving portion 44b. Further, the scrap winding unit 50 is driven by a motor (not shown), and the scrap 12 of the film 12 bundled by the bundle unit 22 is scraped.
It is designed to wind a.

In the bundling device 10 having such a structure, in the initial state, the upper and lower sealers 29a and 29b are opened vertically as shown by the solid line in FIG. From the roller 18 to the clamp portion 44. Then, from this initial state, the feed roller 16
Servo motor 32, upper and lower sealers 29a, 29b, clamp portion 44, transfer means 26 and cutter 30a,
The articles 24 are sequentially bundled by being driven according to the time chart shown in FIG. still,
In the above time chart, the process of completing the bundle of one article 24 is shown as a 360 ° cycle.

That is, first, the clamp pin 44a of the clamp portion 44 is pressed against the receiving portion 44b to clamp the film 12, and the servomotor 32 is controlled to rotate in the forward direction. That is, first, in this forward rotation control, the motor 32 causes the roller 1
The rotation is restrained by the braking force generator until the film tension on the downstream side of 6 becomes equal to or more than the set value T1.

In this state, the article 24 placed in front of the intersection of the film 12 with the transfer path 25 is moved backward by the transfer means 26 and sent to the bundling means 28. The transfer means 26 slides on the sliding plates 25a, 25a of the transfer path 25 while pushing the article 24 with the fingers 34 to move it. It is assumed that the article 24 uses a plurality of laminated tablet sheets.

The article 24 in front of the film 12 is moved by the transfer means 2
When it is sent to the rear bundling means 26 at 6, the article 24
When the film 12 comes into contact with the leading end of the central portion in the traveling direction and the article 24 further moves, the film 12 is drawn backward together with the article 24 and wrapped around the article 24 as shown by the solid line in FIG. Go.

At this time, as the film 12 is drawn rearward, the film tension downstream of the roller 16 of the feeding means increases, and when the tension reaches the set value T1, the motor 32 resists the braking force. When the rotation is detected by the rotation detecting portion, the drive control means 33 causes the motor 32 of the feeding means to rotate in the forward direction in the X direction for a predetermined short time or a predetermined rotation angle, and then to stop again. A small amount of film 12 is fed out from the. In this way, during the forward rotation period, the motor 32 repeats the forward rotation / stop every time the film tension reaches the set value T1 to feed the film 12 little by little from the raw material portion 14.

Therefore, the film 12 is gradually fed out from the original fabric portion 14 in accordance with the amount of backward pulling by the article 24, and the feeding amount is appropriate for the size of the article 24 to be bundled. The film 12 is automatically adjusted, and the film 12 is prevented from being excessively fed out during the revolution.

In this way, the article 24 is covered with the film 12 around its outer periphery, and the upper and lower sealers 29a, 29b are provided.
When you pass through the space, finger 3 at that point (120 °)
4 is stopped and the intermittent transfer of the article 24 is stopped. Also,
In this way, at the same time when the article 24 is stopped, the feeding of the film 12, that is, the normal rotation control of the motor is completed, the portal stopper 42 descends from the point of 120 °, and the article 24 is reversed at both sides of the portal stopper 42. The movement of the lower sealer 29b is prevented, and the lower sealer 29b rises from the point of 120 ° and stops at a predetermined position between the lower surface and the upper surface of the article 24. Here, in this embodiment, it rises to a position slightly lower than the upper surface.
When the gate-shaped stopper 42 descends, the film 12 disposed above the article 24 at the upper side of the cutout portion in the central portion is pushed downward to surround the film 12 at the upper side of the article 24 and The film 1 placed below the article 24 due to the rise of the sealer 29b.
2 is pushed up, and the film 12 is wrapped around the lower side and the rear side of the article 24 (the side opposite to the traveling direction).

On the other hand, the servomotor 32 is switched to the reverse rotation control from the point of 120 ° after the normal rotation control is completed. As a result, the feed roller 16 rotates in the Y direction and reversely feeds the film 12 and pulls it back to apply a predetermined tension due to the back tension to the film 12 at a portion between the feed roller 16 and the clamp portion 44. At this time, film 1
The rotation speed of the servo motor 32 decreases as the tension increases due to the pulling back of No. 2, and finally when the tension is balanced with the maximum drive torque generated by the load current, that is, when the tension reaches the set value T2. Then, the rotation of the servo motor 32 stops. Therefore, since the back tension is applied to the film 12 by the reverse rotation control in which the maximum drive torque of the motor 32 is suppressed to a predetermined upper limit value, the back tension tension value is irrespective of the elasticity of the articles 24 to be bundled. It can be arbitrarily set.

Then, the article 24 is squeezed in the state in which the appropriate tension is applied, and in this squeezed state, the upper sealer 29a of the heat-sealing mechanism portion is lowered from the 220 ° point to the upper and lower sides of the article 24. The overlapping portion of the film 12 surrounding the film is heat-sealed. Then, after the thermal fusion is completed, the clamp portion 44 is released from the point of 230 °,
The cutter 30a is raised to cut the middle portion of the heat-sealed portion. Then, the articles 24 are separated while being bundled by the film 12. Also, the cut film 1
2 is a scrap 12a in a state where it is connected by the remaining heat fusion mechanism part, and is sequentially wound around the scrap winding portion 50 by a predetermined length. By winding the scrap 12a for a predetermined length in this way, the remaining heat-sealed portion is removed from the bundle 22.

Next, at 310 °, the reverse rotation control of the servo motor 32 is completed, the gate-shaped stopper 42 is raised to release the reverse movement prevention of the article 24, and the upper sealer 2 is moved.
9a is raised and the lower sealer 29b is lowered to return to the initial state. After that, at 350 °, the clamp part 4
4 is clamped, the forward rotation control of the servo motor 32 is started at 355 °, the feeding of the film 12 is set to the standby state, and the intermittent movement of the finger 34 is started at 360 ° (0 °). The succeeding article 24 is sent to the gripping means 22. In the article 24 in which the tablet sheets are laminated in this manner, the central portion of the article 24 is bundled with the film 12 one after another. A protective guide (not shown) is provided at the rear corners of the heat-sealing surfaces of the upper and lower sealers 29a and 29b so that the film 12 does not directly contact the corners.

By the way, basically, in the article bundle method and article bundle apparatus 10 of the present invention, the article 24 is used.
When the sheets are bundled, the motor 32 of the feeding means may be reversely rotated to apply the back tension to the film 12 to clamp the article 24, and the reverse rotation control of the motor 32 for driving the feeding means in this manner. By tightening the article by the above, the tightening force can be easily set to the optimum state regardless of the elastic material of the article 24. Therefore, the articles 24 bundled with the film 12
It becomes possible to prevent a part of it from falling out.

Further, since the motor 32 of the feeding means is rotated in the reverse direction to tighten the article 24, when the film is fed by rotating the motor 32 in the forward direction, the motor 32 does not always perform the torque control by generating the braking force. No need to do. That is, the amount of film required to gently circulate the film 12 around the outer circumference of the article 24 to be bundled is obtained, and this is set in advance in the drive control means.
The number of rotations of the motor 32 may be controlled so that the film amount can be quickly output at high speed when the motor 32 is normally rotated. Even in this case, it is possible to deal with various articles having different sizes by adjusting the delivery amount set in advance to the article having the maximum size, and the tolerance for the size of the articles to be bundled can be obtained. Can be largely secured.

In the illustrated embodiment, the feed roller 16 for feeding out the film 12 is provided with the original fabric portion 14.
Although the case where it is provided between the lift roller 20 and the elevating roller 20 is disclosed, the original portion 14 itself is not limited to this and is driven by a motor capable of forward and reverse rotations to control the feeding amount of the film 12 and the addition of back tension. You can also do it. In this case, as shown by the broken line in FIG. 1, the film 12 can be directly stretched from the original fabric portion 14 to the intermediate roller 18, so that the feed roller 16 provided in the above-described embodiment can be eliminated and the bundle bundle The configuration of the entire device 10 can be simplified. However, in the case of controlling the feeding amount of the film 12 by normally rotating the original fabric portion 14 itself by a motor as in this embodiment, it is necessary to control the number of rotations according to the winding amount of the film 12 of the original fabric portion 14. There is.

Further, in the above-described embodiment, the case where the film 12 which can be heat-sealed is used and the articles 24 can be quickly bundled by adhering by heat-sealing is disclosed, but the invention is not limited to this. It is also possible to bond 12 with an adhesive.

Further, in the above-described embodiment, the case where the motor 32 is stopped by the brake force generator to be in the standby state during the forward rotation control is disclosed, but the brake force generator does not necessarily rotate the motor 32. It is not necessary to completely stop it, and it is also possible to apply a braking force and rotate at a fine speed. That is, while the driving torque of the motor 32 is set to a strength that balances the set value T1 of the film tension, the rotation speed is detected by the rotation detection unit while rotating at a very small speed to perform the braking operation, and the downstream side of the feeding means. Each time the film tension exceeds the set value T1 and the rotation detection unit detects that the motor rotation speed is increased by the tension, the motor 32 is accelerated for a predetermined short time or a predetermined rotation angle. You may choose to do it.

Therefore, the tightening force when bundling the articles with the film can be set in an optimum state to prevent the articles from falling off. Further, since the amount of the film fed out by the forward rotation of the motor can be arbitrarily set, and the excessively fed out amount can be pulled back by the reverse rotation, a large allowance for the size of the article to be bundled is secured. be able to.
