Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a device for attaching a packaging straw body to the side surface of a pack container, etc., containing juices, etc.

(Prior art) Conventionally, as this type of device, for example, JP-A-56-
There is one published in Publication No. 131139. That is,
In this conventional device, as shown in FIG. 10, an attachment 32 equipped with a clamping body 30, a heater stand 31, etc., and a chain 33 are disposed on the side of a conveyor 15 on which containers 16 are conveyed, as shown in FIG.
At the same time, the continuous packaging straw body 1, in which a large number of straws are successively packaged in advance, is cut and separated into individual packaging straw bodies by a cutter 7, and then transported to the orbital position of the attachment 32. A transfer device 35 is separately provided, and the packaging straw bodies are individually gripped by the attachment 32 of the device 34, and transferred and attached to the side surface of each container 16.

(Problems to be Solved by the Invention) However, in the conventional device, the attachment 32 for gripping and transporting the packaging straw body is composed of a clamping body 30 manufactured with great precision, a heater stand 31, etc. Not only is the structure complicated, but also a set of attachments 32 can only hold one packaging straw. Therefore, in order to quickly transfer and attach packaging straws, the attachments 32 are connected to a chain 33. As a result, the structure of the entire device becomes more complicated, the manufacturing cost of the device increases, and maintenance management is also very complicated and the workability is poor.

Furthermore, in the conventional device, since the packaging straw body is held during transportation by the clamping action of the clamping body 30 of the attachment 32, when the size of the packaging straw body is changed, the packaging straw body is held during transportation. The setting of the clamping force etc. of the clamping body 30 must be changed each time, which is a complicated work, and in reality, the size of the packaging straw body that can be clamped by the clamping body 30 is fixed. It also had the problem that its scope of use was very limited.

The present invention was devised in view of the above-mentioned conventional problems, and its purpose is to provide a very simple means for supplying and pasting the packaging straw body to the side of the container. In addition, even if there is a slight change in the size of the packaging straw body, there is no need to adjust each part, and reliable transfer and attachment work can be performed without worrying about the dimensions of the packaging straw body. At the point.

(Means for Solving the Problems) The present invention has been constructed to achieve the above object and to solve the problems of the conventional technology. A belt 12 is wound around a vacuum rotor 10 having a vacuum rotor 10, and a ventilation means is provided on the belt 12 to cause the suction effect of the suction holes 19 to be held on the surface of the belt 12 so as to be able to hold the packaging straw 1a. The belt conveyor 11 is arranged so that the packaging straw body 1a held by the belt 12 is supplied to the side of the container 16 and is conveyed together with the container 16 while being pressed toward the container 16 side by the belt 12. The packaging straw body 1a is provided on one side of the conveyor 15 of the conveyor 15 and is conveyed while being pressed against the side surface of the container 16 by the belt 12 of the belt conveyor 11. The heat sealer 17 that rotates in synchronization with the conveyance timing is provided on the side of the conveyor 15.

(Function) Therefore, in the packaging straw body sticking device characterized by the above configuration, the belt conveyor 11
When the packaging straw body 1a is supplied to the bag and is held on the surface of the belt 12 by the suction force of the vacuum rotor 10, the packaging straw body 1a is transferred to the side of the container 16 by the rotational transfer of the vacuum rotor 10. The straw packaging body 1a is transferred together with the container 16 while being pressed by the belt 12, and in this state, the heat sealer 17 rotates and comes into contact with the straw packaging body 1a, thereby ensuring that the straw packaging body 1a is welded and pasted. It can be done. Moreover, since the packaging straw body 1a is held by the belt conveyor 11 by the suction action of the vacuum rotor 10, the packaging straw body 1a is held by the belt conveyor 11.
Even if the size of the packaging straw body 1a is slightly changed, there is no problem in attracting and holding the packaging straw body 1a. Furthermore, the belt conveyor 1
Since the packaging straw body 1a can be held by the suction force of the belt 12 and the vacuum rotor 10 around which the belt 12 is wound, the structure is very simple.

(Embodiment) Hereinafter, one embodiment of the present invention shown in the drawings will be described.

In FIG. 1, reference numeral 1 designates a continuous packaging straw body made by wrapping straws 2 folded in two with continuous upper and lower films 3 and 4 at equal intervals as shown in FIG. As shown in FIG. 3, a recess 6 is formed on the outer peripheral surface of the continuous packaging straw body 1 at the same pitch as the packaging pitch of the straw 2, and a suction hole 18 is provided at the bottom of the recess 6. Recess 6
A first grooved vacuum rotor is shown in which a suction effect is produced in the suction hole 18 only when the rotor is located on the right half circumferential surface in the drawing.

The second vacuum rotor 8 is arranged in parallel with the first grooved vacuum rotor 5 with a slight gap therebetween, and the second vacuum rotor 8 rotates independently of the first grooved vacuum rotor 5. The direction is reversed. 10 has suction holes 19 on the outer circumferential surface of the second vacuum rotor 8 in the same way as the second vacuum rotor 8.
A third vacuum rotor is shown which is provided at the same pitch as the suction holes 9 of the vacuum rotor 8, and the third vacuum rotor 10 is arranged in parallel with the second vacuum rotor 8 with a slight gap. Then,
Moreover, it is rotatable in the opposite direction to the second vacuum rotor 8. Reference numeral 11 denotes a belt 12 which is narrower than the width of the continuous packaging straw body 1 and has a large number of small holes 13 protruding from its entire surface, as shown in FIG.
One side of the belt 12 is wound around the third vacuum rotor 10, and the other side of the belt 12 is wound around the drive roller 14.
A belt conveyor with winding racks is shown. Further, the belt conveyor 11 is provided on the side of the transport conveyor 15 that conveys the containers 16 so that the containers 16 and the belt 12 move in parallel at the same speed with a very small interval between them.

Reference numeral 20 denotes a timing device for timing the supply of containers 16 to the transport conveyor 15, and when the suction hole 19 of the third vacuum rotor 10 faces the transport conveyor 15, the container 1 is fed to the front of the transport conveyor 15.
Adjusted so that 6 exists. 17 indicates a rotary heat sealer, and the rotary heat sealer 17
As shown in FIG. 6, the tip portions 17a, 17a of the sealer 17 are accessed from above and below the belt 12 of the belt conveyor 11 so that the tip portion 17a can come into contact with the side surface of the container 16 being conveyed on the conveyor 15.
It is arranged so that it protrudes. Incidentally, the vacuum rotors 5, 8, 10, the rotary heat sealer 17, and the cutter 7 all rotate synchronously.

The present embodiment has the above-mentioned structure, and its operation will be explained next. First, as shown in FIG. When the device shown in FIG. 1 is operated while continuously supplying the continuous packaging straw body 1, the continuous packaging straw body 1 moves on the outer peripheral surface while being attracted to the first grooved vacuum rotor 5. The straws are transferred and cut between the straws 2 by the cutter 7. The cut packaging straw body 1a is still transferred by the first vacuum rotor 5, and then is sucked and adsorbed by the suction hole 9 to the second vacuum rotor 8, and is placed at the upper part of the drawing of the second vacuum rotor 8. will be transferred to. The transferred packaging straw body 1a is transferred to the third
Due to the suction action of the vacuum rotor 10, it is further held on the outer peripheral surface of the belt 12 of the belt conveyor 11 and transferred to the conveyor 15 side that conveys the container 16. At this time, a container 1 is placed on the conveyor 15 at a position facing the third vacuum rotor 10.
6, the packaging straw body 1a is pressed into contact with the side surface of the container 16 by the belt 12 of the belt conveyor 11, and is conveyed forward while maintaining that state. Further, the transported packaging straw body 1a is sealed at the upper and lower ends 5 by a rotating heat sealer.
0.50, and the packaging straw body 1a is welded to the side surface of the container 16 as shown in FIG. 7 of the drawings.

In the above embodiment, a large number of small holes are formed in the belt as a means for holding the packaging straw body on the belt of the belt conveyor by the suction force of the vacuum rotor, but the present invention never does this. The design can be changed freely without being limited to, for example, the 8th
As shown in the figure, both ends 21, 21a of the vacuum rotor 10a have a thickness t of the belt 12 than the center part.
The vacuum rotor 10a may be made smaller in diameter by twice its size, and belts 12, 12 may be wound around both ends of the vacuum rotor 10a, and the packaging straw body 1a may be sucked and adsorbed through the central suction hole 19a. In short, it is sufficient that the belt wound around the vacuum rotor is provided with ventilation means so that the packaging straw body can be held by the suction force of the vacuum rotor.

In the above embodiment, the first grooved vacuum rotor and the second vacuum rotor are provided as means for supplying the packaging straw bodies to the belt conveyor that conveys the packaging straw bodies, and the continuous packaging straw bodies are cut by the cutter. However, as shown in FIG. 9, the first grooved vacuum rotor and the second vacuum rotor are removed and the cutter 7 is cut. It may be arranged in parallel with the third vacuum rotor 10 of the belt conveyor 11. With this configuration, when the continuous packaging straw body 1 is directly supplied onto the outer peripheral surface of the third vacuum rotor 10 of the belt conveyor 11, the continuous packaging straw body 1 is directly supplied onto the outer peripheral surface of the third vacuum rotor 10 of the belt conveyor 11.
The cutter 7 cuts the packaging straws 1a when they are sucked and transferred to the container 1, and the cut individual packaging straws 1a are transferred as they are to the conveyor 15 that carries the containers 16 in the same manner as in the above embodiment. .

As described above, in the present invention, the structure for supplying the packaging straw body onto the outer circumferential surface of the vacuum rotor of the conveyor is not limited to the above-mentioned embodiment, and the design can be changed freely.

In addition, the specific configurations of the heat sealer, belt conveyor, cutter, etc. that are essential to the present invention are all subject to design changes within the scope of the present invention, and it goes without saying that the packaging form of the packaging straw body It does not matter the type or shape of the container.

(Effects of the invention) As described above, the present invention allows the transportation of the packaging straw body to be attached to the container by a belt conveyor formed by winding a belt around a vacuum rotor. Because it is attached to the container using a separate heat sealer,
Compared to the conventional system, in which a large number of attachments such as clamping bodies and heater stands with complicated structures are installed and moved in circulation, the configuration can be significantly simplified, and as a result, the manufacturing cost can be significantly reduced. We have achieved exceptional results by reducing the amount of electricity and making maintenance management easier. In particular, the present invention is designed so that the straw packaging body supplied to the belt of the belt conveyor for pressing and holding the straw packaging body against the side of the container being transferred can be directly held by the suction force of the vacuum rotor. , the holding means for the straw package becomes very simple, and the manufacturing efficiency is also good, which is a practical benefit.

Furthermore, since the present invention is constructed so that the packaging straw body is suctioned and held by the suction action of the vacuum rotor of the belt conveyor and transferred, there is no problem even if the size of the packaging straw body is changed. There is no need to change or adjust each part, and it is possible to reliably hold and transfer straws of any shape or size, which not only improves the reliability of the work, but also increases the range of applications. It has also brought great benefits. Furthermore, in the present invention, after the straw packaging body is supplied to the side of the container, the straw packaging body is pressed against the container side with a belt and welded to the container with a sealer while maintaining its position. There is no misalignment when attaching the straw packaging to the side of the container.
Since the straw packaging can be properly pasted, and a sealer is used as the means for adhering the straw packaging to the container, the cost of using adhesives and the costs associated with generally known adhesive application methods are reduced. In addition to not requiring high management costs, there is no risk that the adhesive will dry and harden and lose or deteriorate its adhesive strength between the time the adhesive is applied to the container and the straw packaging body is supplied. It also has the advantage that pasting work can be performed.
