Conventionally, it has been a practice to add some kind of item to a packaging container for food or other items, such as attaching a packaged product such as a straw, spoon, etc. in a pouch to the side of the packaging container using an automatic machine. In addition, other items are also added to other packaging containers (for example, cans).

In this case, after the packaging container, which is the transported article, is continuously transported by a conveyor, it is transferred to a bucket wheel that accommodates the packaging container, and while the wheel is rotating, the packaging of the sachet is pasted to the packaging container, or other A method of adding items such as

[Problem that the invention seeks to solve]

In the conventional method, a wheel is required for supplying the packaging container as the object to be transported to the bucket wheel, and a wheel for transporting the packaging container as the object to be transported from the bucket wheel. was limited to cylindrical wheels due to the relationship between wheels. This inevitably complicates the structure of the device, and it is difficult to handle devices with a cross section other than circular with a bucket wheel.

The present invention has been made in view of the above points, and the present invention has been developed by omitting a wheel for supplying a packaging container, which is an article to be transported, to a bucket wheel and a wheel for carrying out the packaging container from the bucket wheel. During the transfer of conveyed articles, such as packaging containers, which can be simplified and directly supplied from a conveyor to a bucket wheel, and which can also be handled even if the cross section is not circular, such as a semicircular one. An object of the present invention is to provide a device for supplying and unloading articles such as packaging containers to a bucket wheel for pasting and adding required articles to a bucket wheel.

Still another object is to provide an apparatus for supplying and discharging articles, such as packaging containers, to the bucket wheel and carrying them out from the wheel using a simple mechanism.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention, as a first invention, stores and transfers conveyed articles, and during transfer, attaches necessary articles such as sachet packages to the conveyed articles such as packaging containers having a semicircular cross section. A conveyed article positioning section moves linearly at a fixed pitch by a bucket wheel equipped with a bucket on the outer periphery and a protrusion that pushes the conveyed article to supply the conveyed article to the bucket wheel and to receive the conveyed article. A device for supplying and unloading articles to and from a bucket wheel consisting of a bucket conveyor and a bucket conveyor, wherein the bucket wheel has an odd number of buckets,
The pitch of the buckets of the bucket conveyor is twice the pitch of the buckets of the bucket wheel, and the buckets of the bucket conveyor and the buckets of the bucket wheel are in the same phase at positions near the wheel and the conveyor. In this device, the conveyed articles are fed to the bucket of the bucket wheel at that position and sent out from the bucket at the same position.

In addition, in the second invention, the bucket wheel of the above device equipped with buckets on the outer periphery in order to attach a required article to the conveyed article opens and closes a valve by a valve switching lever on each of the odd number of buckets on the outer periphery of the wheel. The pitch of the bucket is such that the suction pipe is open and provided in a vertical position, and the conveyed article positioning section is formed by a protrusion that pushes the conveyed articles of the bucket conveyor that moves linearly below the bucket wheel. The pitch of the bucket of the bucket conveyor and the bucket of the bucket wheel are set at twice the pitch of the bucket of the bucket wheel, so that the bucket of the bucket conveyor and the bucket of the bucket wheel are in the same phase at a position close to the wheel and the conveyor, and a fixed cam and a movable cam are attached to the main body of the device. is provided so that the cam portion faces the locus of the circumferential rotation of the actuating roller for swinging the valve switching lever, and the fixed cam pushes the valve switching lever to bring the bucket into a vacuum suction state of the conveyed articles. On the other hand, the movable cam is linked to the rotation of the bucket wheel and swings every two pitches of the bucket wheel's movement, and when the bucket of the bucket wheel comes to the above position close to the bucket conveyor, the valve is switched. By pushing the lever, the suction state of the bucket of the bucket wheel is cut off, and the transported article is brought into the unloading state, and the transported article is supplied to the bucket at the above-mentioned adjacent position and sent out from the bucket at the same position.

Therefore, when the bucket containing the conveyed articles to which the desired articles are attached comes close to the wheels and the conveyor and sends the conveyed articles onto the conveyor during rotation, the bucket is stored in every other bucket. Since the conveyor can supply the transported goods from the conveyor to the bucket of the bucket wheel adjacent to the bucket, the transported goods can be supplied from the bucket of the bucket conveyor that moves in a straight line to the bucket on the circumference of the bucket wheel without any hindrance. .

Further, in the second aspect of the invention, when the bucket wheel rotates in the above device, the fixed cam pushes the valve switching lever to suction the rotating empty bucket to convey the articles from the conveyor to the bucket of the bucket wheel. On the other hand, the movable cam pushes the valve switching lever in the opposite direction to the pushing direction of the fixed cam to cut off the suction state of the bucket that sucks and accommodates the conveyed articles every two pitches, and removes the conveyed articles from the bucket. is sent onto the conveyor.

〔Example〕

Next, embodiments of the present invention will be described based on the accompanying drawings.

FIG. 1 shows a front view of an apparatus for attaching a spoon to a packaging container, which is equipped with a device for supplying and unloading articles to a bucket wheel for transferring articles according to the present invention. In the figure, reference numeral 1 denotes a bucket conveyor for storing and transferring (rotating) a packaging container P having a semicircular cross section as shown in FIG. The packaging containers P, which are linearly conveyed one after another, are adsorbed and accommodated in the bucket of the bucket wheel 1, while rotating, and the upper part contacts the pouch B containing the spoon, which is transferred by the package transfer drum 2. Then, the pouch B is attached to the side surface of the packaging container P (bottom surface on the bucket conveyor) as shown in FIG. It is sent out and carried out to the left.

As shown in Figure 3, the spoon-containing pouch B is made by sandwiching two synthetic resin films and heat welding them at predetermined points.
Each bag is separated from a continuous band-shaped package C during the process.

4 to 10 show the feeding and unloading of conveyed articles to and from the bucket wheel by the apparatus of the present invention, in which a packaging container P, which is a conveyed article, is loaded onto the bucket conveyor 3 from the bucket wheel 1. During the rotation of the packaging container, small bags B of the required articles are attached to the upper part and transferred downward, and the packaging containers P' to which these small bags are attached are sequentially sent out from the wheel and conveyed by the conveyor. It shows the state to which it is going. This bucket wheel 1 has a bucket D which is an odd number (15 in the figure) of packaging containers, and a bucket conveyor 3.
is arranged to move horizontally below the bucket wheel 1. The pitch of the bucket, that is, the pitch of the packaging container positioning portion formed by the ratchet type protrusion that pushes the packaging container, is formed to have twice the length of the pitch of the bucket of the bucket wheel, and the wheel and the conveyor are located close to each other. Both buckets are formed so that they are in the same phase at a position directly below the wheel.

In addition, the bucket wheel 1 is shown in FIGS. 11 and 1.
As shown in Figure 2, the bucket D provided on the outer periphery
An intake pipe N for adsorbing the packaging container P by vacuum action is opened at the bottom of each semicircular cross section, and each intake pipe N has a valve for applying or blocking intake air by the vacuum action, and a valve for opening and closing the valve. A valve switching lever L is provided, and by swinging the valve operating lever,
The suction pipe N is designed to adsorb the packaged article to the bucket by the suction action of a vacuum, or to shut off the suction by blocking the suction.

On the main body side where the bucket wheel is installed, a fixed cam 4 is directly supported on a frame 9, and a movable cam 5 is rotatably supported on the frame 9 via a bearing. These two cams are provided so that their operating portions face the rotation locus of the actuating roller L' pivotally supported at the tip of the valve switching lever L mentioned above.

Figures 13 to 16 show the bucket wheel 1.
A diagram showing the relationship between each of the valve switching levers L provided above and rotating on the circumference and the fixed cam 4, and the relationship between the lever and the movable cam 5 that rotates in conjunction with the bucket wheel 1. It is.

The above-mentioned fixed cam 4 pushes the actuating roller L' that is pivotally supported at the tip of the rotating valve switching lever L to bring the intake pipe N into a vacuum suction state for adsorbing the packaging container. On the other hand, the movable cam 5
In conjunction with the rotation of the bucket wheel 1, the circular cam 6 rotates once every time the bucket D of the bucket wheel rotates by two pitches of the bucket interval, and swings via the crank 7 and the connecting rod 8. When the bucket D of the bucket wheel comes to a position directly below the wheel close to the bucket conveyor 3, the valve switching lever L is pressed to shut off the intake air from the intake pipe N, thereby cutting off the suction of the packaging container P and transporting it to the conveyor 3. It is designed to fall and be carried out.

Next, the operation of the device according to the present invention will be explained.

As shown in FIG. 4, the packaging container _P1 , which has been conveyed by the bucket conveyor 3 and has come directly under the bucket wheel 1, is adsorbed and accommodated in the bucket D of the bucket wheel. Next, when the wheel 1 (hereinafter the bucket wheel is abbreviated as wheel) rotates clockwise by two pitches of the interval between the buckets, the packaging container P ₂ held in the next bucket part of the bucket conveyor 3 is moved from the previous one. The packaging container _P1 is adsorbed into one of the buckets placed directly below the wheel. In this way, as the wheel 1 rotates, every other packaging container on the bucket conveyor is suctioned into the bucket of the wheel 1 as P ₂ , P ₃ , etc., and the packaging container P ₁ is placed in a circle. At the top of the circumferential rotation, the package transfer drum 2 transfers and attaches the pouch B to the bottom surface of the packaging container on the conveyor 3 (the side surface of the container when it becomes a product) (see FIG. 5). The packaging containers P ₁ ′, P ₂ ′, and P ₃ ′ to which the pouch B was affixed are sequentially transferred downward, and the packaging containers P 1 ′, P 2 ′, and P 3 ′ to which the pouch B is affixed are transferred downward.
P ₁ ' reaches a position one pitch before the position where the packaging container was previously sucked and accommodated (see FIG. 6). At this time, the bucket of the bucket conveyor, which has twice the pitch of the bucket of the wheel, is located at the lower end of the wheel where the packaging container P ₇ was sucked and received from the bucket conveyor 3 before. The upper packaging container _P8 is adsorbed and accommodated in the bucket D of the wheel. Next, when the previously suctioned packaging container P ₁ ′ comes to the above position, the valve switching lever and the cam engage as described later, and the packaging container P ₁ ′, which has been stopped from being suctioned by the bucket D, is moved to the bucket tray. It falls onto a conveyor and is carried out (see Figure 7). At this time, the next empty bucket D', which had been adsorbed and accommodated in the packaging container P ₁ ' of the wheel 1, is in an adsorbed state, and the next packaging container on the bucket conveyor 3
P ₉ moves in synchronization with the empty bucket D′, and when the empty bucket reaches the lowest position on the wheel, the packaging container P ₁ which was adsorbed and accommodated in the empty bucket is dropped and carried out first. ' is conveyed on a conveyor (see Figure 8). Thereafter, the packaging container P ₂ ' is dropped and carried out in the same manner as above (see Figure 9), the packaging container P ₁₀ is sucked and stored in the bucket D' of the wheel, and the packaging container P ₃ ' on the wheel side is dropped and carried out. This operation is repeated one after another.

Next, the operation when the bucket wheel 1 attracts the packaging container P to the bucket D and when the suction is stopped will be described.

Figure 13 shows the bucket wheel 1.
This shows the state in which the valve switching lever L ₁ of the intake pipe D ₁ is pushed by the movable cam 5 to cut off the intake air, and the packaging container P ₁ ' separates from the suction state and falls and begins to be conveyed onto the conveyor 3. At this time, the valve switching lever L ₂ of the wheel bucket D ₂ is pushed by the fixed cam 4 and its intake pipe is in the suction state, while the movable cam 5 finishes pushing the switching lever L ₁ and closes the valve. The switching lever _L2 is in a state where it has retreated from the rotation locus of the operating roller. FIG. 14 shows a state in which the bucket wheel has rotated clockwise by 1/2 of the pitch of the bucket from the state shown in FIG. 13. At this time, the bucket D ₂ of the bucket wheel 1 is at the bucket storing position close to the conveyor 3, and absorbs and stores the packaging container P ₁₆ conveyed on the conveyor 3, and the movable cam 5 switches the valve. It remains retracted from the path of the actuating roller of lever L ₂ . Also, at this time, the valve switching lever that puts Bucket D ₃ in the adsorption state
_L3 passes around the outer periphery of the fixed cam 4 without being pushed. FIG. 15 shows a state in which the bucket wheel 1 has been rotated clockwise by one pitch of the bucket from the state shown in FIG. The lever _L2 is moved by the clockwise rotation of the movable cam 5, and the actuating roller of the valve switching lever _L3 is pushed, cutting off the intake air from the intake pipe of the bucket _D3 , and the packaging container _P3 ', which had been sucked, is moved to the conveyor. 3 and is carried out.
Further, the valve switching lever _L4 of the bucket _D4 , which was in the non-adsorption state, is pushed as its roller comes into contact with the fixed cam 4, and the intake pipe of the bucket _D4 becomes the suction state. FIG. 16 shows a state in which the bucket wheel has been rotated clockwise by 1/2 pitch of the bucket pitch from the state shown in FIG. 15, that is, a state in which it has been rotated clockwise by two pitches from the state shown in FIG. That is, at this time, the movable cam 5 is retracted from the state shown in FIG. 15, and the valve switching lever L ₄ of the bucket D 4 of the wheel 1 is moved as the packaging containers P ₁ ′ and P _{3 ′} are transported. Without being pushed by the lever _L5 , the intake pipe of the bucket _D4 maintains its suction state and reaches directly below the wheel, where it sucks and accommodates the packaging container _P17 . In this way, the fixed cam 4 causes the valve switching lever L to always keep the suction pipe to which it belongs, while the movable cam 5 moves the packaging containers that are sucked and transferred from every other bucket of the bucket wheel to the conveyor. It is possible to carry it out on the 3rd floor.

In addition, although the embodiment has described an apparatus in which the bucket wheel is in a vertical position, the present invention is not limited to this, and does not preclude supplying and unloading of conveyed articles with the wheel in a horizontal position. Also, any article can be selected to be attached to the conveyed article, rather than being packaged in a sachet.

〔Effect of the invention〕

Since the present invention is configured as described above, the device of the first invention allows the bucket wheel to move linearly compared to the conventional device for supplying and unloading articles to and from a bucket wheel of this type. By supplying conveyed articles from the conveyor to every other bucket of a bucket wheel having an odd number of buckets, and discharging the articles at the same position, a wheel for inserting articles from the conveyor into the bucket wheels and It is possible to eliminate the need for wheels for transporting articles from the bucket wheel to the conveyor, and to simplify the supply and delivery device for conveying articles to the bucket wheel for attaching required articles to the conveyed articles. The present invention has the advantage that it is possible to handle conveyed articles having a cross section other than circular, for example semicircular, which has been difficult to handle with conventional devices of this type.

Further, according to the device of the second invention, which specifies a mechanism for storing and carrying out conveyed articles in the bucket of the bucket wheel of the device of the invention, the mechanism is provided in the device body by a fixed cam and a movable cam. Since this can be done by simply switching the suction action of the bucket wheel, the structure can be simplified without the need for electrical control of vacuum valves, etc., and a device with low power consumption can be provided.
