Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to containers such as straw packaging bodies, which can suitably adhere a packaging body containing a straw or the like to the side surface of a container such as a beverage container. This invention relates to a pasting device.

(Prior art) Conventionally, as this type of pasting device, for example,
-There is one published in Publication No. 111980.

That is, as shown in FIG. 4, in this conventional type, a rotatable suction drum 4e is provided on one side of the conveyor 1 for conveying the containers 2, and a cutter 30 is provided facing the suction drum 4e. While cutting and separating the continuous packaging bodies 6 such as straws supplied to the suction drum 4e into individual straw packaging bodies 6a with the cutter 30, the individual straw packaging bodies 6a are separated from the side of the container 2 by the suction drum 4e. It is configured to be supplied to the side and attached.

Therefore, according to this means, automatic pasting work can be performed simply by supplying the continuous package 6, such as a straw, which has been continuously packaged in advance, to the suction drum 4e.

(Problems to be Solved by the Invention) However, in order to improve the packaging efficiency, the continuous packaging body 6 for straws used in the above-mentioned adhesive elements is usually made up of individual straws 31 as shown in FIG.
The reality is that the packaging pitch is kept as short as possible.

Therefore, in the conventional pasting device, when using continuous packaging bodies 6 such as straws of this kind, the individual packaging bodies 6a cut by the cutter 30 are suctioned at small intervals of the packaging pitch l. These packages 6a... are held on the surface of the drum 4e and transferred to the side of the container 2 in a tight state.
When transferred to the side of the container 2, situations often arise in which multiple packages 6a... are stuck to the container 2 at the same time, causing a major problem in the reliability of the sticking work. It was.

The present invention was invented in view of the above-mentioned problems of the prior art, and its purpose is to affix individual packages even when the target is a continuous package with a small packaging pitch. The object of the present invention is to prevent the packages from being transferred to the container side in a tight state and to ensure the work of pasting each package.

(Means for Solving the Problems) The present invention does not use only one suction drum as in the past, but uses a plurality of rotating suction drums and provides a difference in rotational speed between these rotary suction drums. Then, the transfer pitch of the package is increased,
It was designed to solve the problems of the conventional system.

That is, the gist of the configuration of the present invention is that the packaging body 6a is placed on one side of the conveyor 1 for conveying the container 2.
A plurality of suction drums 4, 4a, 4b are arranged in parallel to transfer and transfer the package 6a... to the side surface of the container 2, and each suction drum 4, 4a, 4b In order to increase the transfer pitch of the bodies 6a, the rotational speed of at least the last suction drum 4 is set higher than that of the suction drums 4a, 4b of the previous stage.

(Function) That is, in the pasting device characterized by the above configuration, the packages 6a are supplied to the pasting position of the container 2 by being sequentially transferred through a plurality of suction drums. However, at least the last stage suction drum 4 is the same as the previous stage suction drums 4a and 4b.
Since the rotational speed is higher than that of the previous one, the packaging bodies 6a are transferred from the previous stage suction drum to the latter stage suction drum, thereby increasing the transfer pitch. Therefore, the package 6a...
Even if the transfer pitch at the initial stage is very small, the packages 6a... are delivered and transferred by each suction drum, so that they do not approach a tight state at the stage of being supplied to the container 2. Or there is no contact.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

In FIG. 1, 1 indicates a conveyor for conveying the containers 2, and 3 indicates a guide belt provided on one side above the conveyor 1 for guiding the containers 2.

Reference numeral 4 indicates a first suction drum provided on the other side of the conveyor 1, and the first suction drum 4 has a large number of suction holes (not shown) on its outer peripheral surface 5, and the suction drum 4 has a large number of suction holes (not shown). It is configured such that articles such as the continuous straw packaging body 6 can be suctioned and held on the outer circumferential surface 5 by the action.

Reference numerals 4a and 4b indicate second and third suction drums that are arranged in parallel at a predetermined interval on the other side of the first suction drum 4, and one of the second suction drums 4a is the first suction drum. Similarly to 4, the third suction drum 4b has a large number of suction holes on its outer circumferential surface, and the other third suction drum 4b has a large number of recesses 10 on its outer circumferential surface 9 into which the protrusions of the continuous straw packaging body 6 fit. At the bottom of the recess 10, a suction hole is provided for suctioning the continuous straw package 6.

The pitches P, Pa, and Pb of the suction holes of the suction drums 4, 4a, and 4b are set such that the dimensions thereof become larger as they go from the third suction drum 4b side to the first suction drum 4 side. ing. Furthermore, only when the suction holes of the first and third suction drums 4 and 4b are located on the right half of the outer circumference, and when the suction holes of the second suction drum 4a are located on the left half of the outer circumference. It exerts its suction effect only on.

Reference numeral 11 indicates a cutter for cutting and separating the continuous straw package 6 supplied to the third suction drum 4b into individual packages 6a, and 13 indicates a cutter for cutting and separating the continuous straw package 6 supplied to the third suction drum 4b into individual packages 6a. An applicator for spraying and applying adhesive 23 to the back surface is shown.

Further, the driving means for each of the suction drums 4, 4a, 4b will be explained with reference to FIG. 2. Reference numeral 14 indicates a clutch brake provided on an input shaft 16 driven by an electric motor 15 with a reduction gear. Reference numeral 18 designates an index unit having an input shaft 19 connected to the output shaft 17 of the clutch brake 14, and an output shaft 20 at the other end connected to the drive shaft 7 of the third suction drum 4b. Tux unit 18
The third suction drum 4b is driven to rotate intermittently by converting the input rotational drive into a constant intermittent rotational motion.

The clutch brake 14 is provided near the front of the first suction drum 4 and drives the output shaft 17 based on a detection signal from a sensor 22 for detecting the presence of the container 2. The index unit 17 is configured to stop the output shaft 17 at the same time when one cycle of the intermittent rotation drive of the index unit 18, which is operated by the drive of the index unit 17, is completed. Further, the first and second suction drums 4 and 4a have a gear 21a that sequentially meshes with a gear 21 provided on the drive shaft 7 of the third suction drum 4b,
They are configured to rotate synchronously in opposite directions with their rotational speeds being sequentially increased through the shafts 21b...21f.

The present embodiment has the above configuration, and its usage and operation will be explained next.

First, as shown in FIG. 1, the continuous straw package 6 is supplied to the third suction drum 4b, where it is held by suction and rotated. At this time, the continuous straw package 6 is cut into individual packages by a cutter 11. The body 6a is cut and separated.

Next, the individual packages 6a cut and separated by the cutter 11 are transferred from the third suction drum 4b to the next second suction drum 4a, and further transferred to the first suction drum 4. The second suction drum 4 is sequentially transferred to the latter stage.
a rotates at a higher speed than the third suction drum 4b, and the first suction drum 4 rotates at a higher speed than the second suction drum 4a.
The transfer pitches P, Pa, and Pb of the package 6a transferred by 4a and 4b become larger as the package 6a is transferred toward the first suction drum 4 side.

Therefore, the package 6a, whose back surface was coated with the adhesive 28 by the applicator 13 when transferred to the first suction drum 4, was transferred to the side of the container 2 being conveyed by the conveyor 1. At this time, the plurality of packages 6a are not brought into a tight state where they are close to each other, and only the one package 6a facing the container 2 is reliably attached to the container 2.

Furthermore, the index unit 1 according to this embodiment
In the driving means consisting of 8 etc., it is not limited to the case where the containers 2 are conveyed by the conveyor 1 at equal intervals;
Even when the packages 6a are transported at irregular intervals, the work of attaching the packages 6a can be carried out reliably.

That is, when the container 2 is conveyed to a position in front of the first suction drum 4, the container 2 is detected by the sensor 22, so the clutch brake 17 transmits the driving force of the electric motor 15 to the index unit 18. As a result, each suction drum 4, 4a, 4b performs only one cycle of rotation. Furthermore, the clutch brake 17 does not transmit driving force to the index unit 18 unless it receives the next signal from the sensor 22. Therefore, even if the pitch is changed to P when the container 2 is being conveyed at pitch P1 as shown in FIG. 3, the time of one cycle 11 of each suction drum 4, 4a, 4b is always constant. Therefore, only the waiting time T is changed, and the operation of the suction drums 4, 4a, 4b can be accurately synchronized with the timing of transporting the containers 2, regardless of the transport pitch of the containers 2.

It should be noted that the present invention does not require a means to appropriately apply the work of attaching the packages 6a to the containers 2 conveyed at unequal intervals as described above, and the means such as the index unit 18, sensor 22, etc. Each device may be provided as necessary.

Further, in the above embodiment, the suction drum 4...
A total of three are installed in parallel, but the specific number is not a question. In short, it is sufficient to provide a plurality of them in order to sequentially increase the feeding pitch of the package 6a.

Further, in the above embodiment, the three suction drums 4, 4a, and 4b are set to rotate at higher speeds toward the later stages, but the present invention is by no means limited to this, and the main point is to In the invention, when the package 6a is transferred to the suction drum 4 at the last stage, the transfer pitch is only amplified, so the requirement is that at least the rotational speed of the suction drum 4 at the last stage is equal to that of the previous stage. It only needs to be faster than the suction drum.

In addition, the present invention is not limited to packaging for straws, and can of course also be applied to packaging for simple spoons, forks, etc. It does not ask about the type.

(Effects of the Invention) As described above, the present invention includes a plurality of suction drums arranged in parallel for transferring the package to be adhered to a container, and the rotational speed of the suction drum on the latter stage is set to be lower than the rotation speed of the suction drum on the former stage. Continuous packaging with a very small packaging pitch is configured so that the packaging body is received and transported by a suction drum, thereby increasing the transportation pitch. Even when using packaging bodies formed by cutting and separating bodies, the gap between the packaging bodies can be made sufficiently large at the stage of attaching these packaging bodies to containers, so that the packaging bodies can be used as before. It is possible to advantageously avoid the situation where multiple packages are pasted onto the container at once by being supplied to the container in a tight state, and the special effect is that the pasting work can be done reliably and appropriately. I was able to obtain this.

In addition, since the present invention only requires providing a plurality of suction drums and creating differences in their rotational speeds,
Its fabrication is very simple and it can be applied to existing equipment, so its practical value is great.
