BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for supplying a packaged object such as a bottle containing a tablet, which is used to supply an insertion portion into a carton or other packaging material.

[0002]

2. Description of the Related Art A conventional cartoning machine used for packaging small boxes is constructed as shown in FIG. 3, for example.

That is, as shown in FIG. 3, the lowermost carton among a plurality of cartons, which are packaging materials held in a stacked state in the carton magazine 1, is taken out by an take-out section equipped with an adsorbing means for adsorbing to the carton. The taken-out carton drops onto a correction unit 3 provided below the carton magazine 1, and the correction unit 3 causes the front and rear edges of the dropped carton to be conveyed by a carton conveyor 5 that forms a conveyance path. After the position of the carton on the correction unit 3 is corrected so as to be oriented in the orthogonal direction (horizontal direction) that is a predetermined direction with respect to the (front-back direction), the carton is conveyed to the box making unit 7 by the carton conveyor 5. The carton is then boxed, and the carton thus boxed is conveyed to the insertion section 9 for inserting the object to be packaged.

On the other hand, for example, a bottle containing tablets, which is an object to be packaged to be inserted in a carton formed in a box, is supplied to the insertion portion 9 by the supply device, but first, from a feeding portion (not shown) through a guide 11. A plurality of bottles are sequentially fed onto the turntable 13 rotating in the direction of the arrow, and the turntable 1
The bottles are sequentially fed one by one through the guide 17 which is a guide unit connecting the guide 14 on the upper surface 3 and the star wheel 15 so that the bottles are pushed out from the turntable 13 to the star wheel 15 and arranged side by side on the carton conveyor 5. The bottle from the star wheel 15 is delivered to the bucket conveyor 19 synchronized with the carton conveyor 5, and the bottle conveyed on the bucket conveyor 19 is inserted into the carton by the inserting means of the inserting section 9 together with the attached document such as a manual. It is supposed to be done.

At this time, the star wheel 15 is constructed as shown in FIGS. 4 and 5, and the two discs are arranged so as to sandwich the support 15d axially attached to the rotary shaft 15c which rotates in the direction of the arrow in FIG. 15a and 15b are arranged vertically, both discs 15a and 15b are fixed to a support 15d by a fixture 15e, and both discs 15a and 15b rotate together with a rotary shaft 15c.

Further, as shown in FIG. 5, the outer circumferences of the two discs 15a and 15b of the star wheel 15 are displaced by 90 ° from each other in phase and are close to a semi-circle that follows the outer shape of the bottle to be packaged. Four notches 15f are formed in the guide 1
The bottle guided by 7 is pushed sequentially by the next bottle as the discs 15a and 15b rotate, and the cutout 1 is formed.
The bottle fitted in 5f and fitted in the notch 15f is held from below by the holding means provided below the lower disk 15b, and the bottle is held in such a state with the star wheel 15 and the bucket conveyor. The bottle is delivered to the bucket conveyor 19 from the star wheel 15 in this manner by rotating to the position where it is delivered to the container 19.

Next, as shown in FIG. 3, the carton into which the bottle has been inserted is conveyed to an adhesive section 21 provided at the front of the carton conveyor 5, and at this adhesive section 21, the left and right sides of the unfolded state of the carton are transferred. After the flap is glued and gradually raised by the guide, this carton is sent between the pair of adhesive belts 23, 23 arranged along both the left and right sides of the carton conveyor 5, and by the rotation of the pulleys 24, 25. Both the adhesive belts 23, 23 are driven in association with the conveyance by the carton conveyor 5, and the carton is sandwiched between the adhesive belts 23, 23 to adhere the glued flaps to each other to be packaged. The small box packaging of a certain bottle containing tablets is completed, and the bottles thus packed in a box are continuously arranged in front of the carton conveyor 5. It is adapted to be transported to the next work step by 27.

In FIG. 3, reference numeral 29 is a main control box of the boxing machine.

In the case of such a cartoning machine, when the number of revolutions of the cartoning machine is determined, the supply capacity of the supply device for the bottle to be packaged is determined, and at the same time, the carton or the attached document is taken out, and the box is manufactured. The operation timings of the section 7 and the adhesive section 21 are also determined, and the timings such as the supply capacity of the supply device, the extraction timing of the carton and the operation timing of the box making section 7 etc. are set each time according to the rotation speed of the boxing machine. .

[0010]

However, when it becomes necessary to change the number of rotations of the cartoning machine depending on the type of the object to be packaged, conventionally, the supply capacity of the object to be packaged corresponding to the number of rotations and the timing of taking out the carton or the like. Etc. and change them to values corresponding to the new number of revolutions, in particular, it is necessary to change the supply capacity of the packaged item by replacing it with another star wheel with a different number of cutouts. However, there is an inconvenience that it takes a lot of time and effort to change the mechanical capacity corresponding to the type of the packaged object.

The problem to be solved by the present invention is to change the mechanical capacity by easily changing the supply capacity of the object to be packaged by the supply device even when the mechanical capacity needs to be changed depending on the type of the object to be packaged. Is to be able to simplify.

According to the first aspect of the present invention,
A turntable that is rotatably provided in one direction and accumulates on the upper surface a plurality of articles to be packaged that are sequentially fed from a feeding section; and a turntable that is provided in the vicinity of the turntable and is on the turntable. A guide means for guiding the articles to be packaged that are sequentially extruded from the turntable when full, and a package to be packaged at least at two locations on a circular outer peripheral portion that is rotatably provided in the same or opposite direction to the turntable. A notch for inserting an article is formed, and is guided by the guide means and is rotated in a state of holding the article to be packaged inserted in each of the notches from below and supplied to an insertion portion of the article to be packaged into a packaging material. In a device for supplying an object to be packaged, which has a star wheel, which has an arc-shaped peripheral edge having substantially the same curvature as the outer circumference of the star wheel, the insertion of the object to be packaged into each of the notches is prevented. Acceptable freely provided in the star wheel, the arcuate peripheral edge in a state of fitting 挿阻 stop is characterized in that it comprises an auxiliary member forming a continuous shape with the arc of the outer periphery of the star wheel.

At this time, according to the first aspect of the invention, when the supply capacity of the packaged object should be maximized depending on the type of the packaged object, the insertion of the packaged object into all the notches should be allowed. When it is necessary to set each auxiliary member and reduce the supply capacity of the packaged object, set the auxiliary member as necessary to prevent the packaged object from being inserted into the notch at the required location. The supply capacity of the product can be easily changed.

FIG. 1 is a plan view of a part of an embodiment of the present invention, and FIG. 2 is a front view.

In these figures, the same reference numerals as those in FIGS. 3 to 5 designate the same or corresponding parts, and FIG.
The difference from FIG. 5 is that the lid-like body 31 is a semicircular auxiliary member that is substantially the same as each notch 15f of the upper disk 15a.
Is provided to prevent and allow insertion of a bottle containing a tablet, which is an object to be packaged, into each notch 15f, and an attachment piece 31a integrally formed on one end side of each lid-like body 31 is attached by an attachment 33. It is rotatably attached to the upper surface of the disc 15a in the vicinity of each notch 15f so that each notch 15f can be closed and opened, and a fastener (not shown) such as a bolt is used to attach the other end of each lid-shaped body 31. An integrally formed fixing piece 31b is fixed near the periphery of the disc 15a when the lid 31 closes the cutout 15f, and in the center of the disc 15a when the lid 31 opens the cutout 15f. That is to fix it in the vicinity.

At this time, each lid-like body 31 has an arcuate peripheral edge E having substantially the same curvature as the outer circumference of the disc 15a, and each lid-like body 31 is
In a state in which each notch 15f is closed, that is, in a state in which the insertion of the bottle into the notch 15f is blocked, the arc-shaped peripheral edge E of each lid-shaped body 31 is circled as shown by the one-dot chain line in FIG. The plate 15a has a continuous shape with the same curvature as the arc of the outer periphery of the plate 15a. By forming such a continuous shape, the lid-like body 31 closes the notch 15f and the notch 15f.
With the bottle inserted into the star wheel, the star wheel 1
Even if 5 rotates, the bottle smoothly contacts the periphery of the star wheel, and the bottle does not get caught on the star wheel 15 during the rotation.

Therefore, depending on the type of bottle to be packaged,
All notches 1 when bottle capacity should be maximized
Each lid-shaped body 31 has each cutout 1 to allow the insertion of the bottle into the 5f.
Each lid-like body 31 is held so that 5f is opened, and the bottle supply capacity is 3/4, 1/2, 1 /
4 When it becomes necessary to lower each of them, the notch 1 corresponding to the required lid-like body 31 for preventing the bottle from being fitted into the notches 15f at one, two, and three places depending on the supply capacity.
By holding each lid-shaped body 31 so that 5f is closed, it is possible to easily change the supply capacity of the bottle, and replace it with another star wheel having a different number of notches as in the conventional case. Therefore, it is possible to simplify the change of mechanical capacity.

Further, since each lid-like body 31 is rotatably attached to the disc 15a and can be fixed at a predetermined position by a fastener, the opening and closing work of the notch 15f by the lid-like body 31 can be performed very easily. it can.

In the above embodiment, the case where the auxiliary member is a semicircular lid 31 having substantially the same shape as the notch 15f and each notch 15f is opened and closed by each lid 31 will be described. However, the auxiliary member does not have to have the same shape as the cutout, and may be, for example, an arc-shaped member having substantially the same curvature as the outer circumference of the star wheel, and at least prevents the insertion of the packaged object into each cutout. It suffices as long as it has an arcuate peripheral edge having a continuous shape with the same curvature as the arc of the outer circumference of the star wheel in the state of being prevented from being fitted and inserted.

The auxiliary member does not have to be rotatably attached to the disc 15a like the lid-like member 31 described above, but may be any structure that is detachably attached to the star wheel 15.

Further, in the above-mentioned embodiment, each of the disks 15a and 15b of the star wheel 15 has four notches 15f, but the number of notches is not limited to four, but two, The present invention can be implemented in the same manner even when the number is three or five or more.

Needless to say, the object to be packaged is not limited to the above-mentioned bottle containing tablets, and the shape of the notch at this time may be adapted to the shape of the object to be packaged.

[0023]

As described above, according to the invention described in claim 1, it is possible to prevent and allow the insertion of the packaged object into each notch of the star wheel, and to prevent the outer periphery of the star wheel from being inserted and prevented. Since an auxiliary member having a circular arc-shaped peripheral edge that has the same curvature as the circular arc is provided, depending on the type of the object to be packaged, the object to be packaged can be inserted into the notch at a necessary location according to the supply capacity of the object to be packaged. By arranging the necessary auxiliary members to prevent this, it is possible to easily change the supply capacity of the packaged item, and it is not necessary to replace it with another star wheel with a different number of notches as in the past, It becomes possible to simplify the change of ability, and the change time can be greatly shortened.
