Description

[Detailed description of the invention] (Field of industrial application) The present invention is suitable for attaching an adhesive object such as a straw package to the side of a container for drinking water, etc., especially a flexible bag-like container. The present invention relates to a pasting device.

(Prior art) Conventionally, as this type of pasting device, for example,
There is one published in Publication No. 54-111980.

That is, as shown in FIG.
e is provided so that the stuck object 10 such as a straw package supplied to the suction drum 3e can be transferred to the side facing the conveyor 1, and the stuck object 10 transferred by the suction drum 3e to face the container 2 is It is configured to be taken out by a swingable lever 50 and adhered to the side surface of the container 2 via an adhesive 19 applied with an applicator 12e.

However, in this conventional device, the suction drum 3
Not only is the structure of the swinging lever 50 for taking out the adhesive material 10 on the e side and transferring it to the container 2 side complicated, but the transfer operation is less reliable. In particular, when the container 2 is a soft packaging bag or the like as shown in FIG.
0 simply by swinging the lever 50, the adhesive object 10 cannot be reliably adhered to the soft container 2, which easily deforms, and the adhering work becomes even more difficult. It was causing a point.

Therefore, in the past, as another pasting device, for example, a device as shown in FIG. 9 has been developed.

This device has guide belts 17e and 13e for sandwiching and guiding the container 2 on both the side of the suction drum 3e on one side of the conveyor 1 that conveys the container 2 and on the other side facing this. They are provided facing each other with a width l smaller than the width.

In this device, the container 2 conveyed by the conveyor 1 is transported by both guide belts 17e, 13 having a narrow interval l.
By holding the container 2 between the containers 2 and 3e, the container 2 can be forcibly brought into pressure contact with the object 10 on the side of the suction drum 3e, and the reliability of the work of attaching the object 10 to the side surface of the container can be improved. It is.

(Problems to be Solved by the Invention) However, in the conventional device, as shown in FIG.
This creates a problem in that the position at which the adhesive object 10 is attached to the container 2 is shifted from the front side of the container 2 to the front side thereof.

Moreover, the container 2 is then moved to the guide belt 13e.
and the suction drum 3e, but since the distance l between the two is set narrow in order to press the container 2 against the suction drum 3e, if the adhesive 19 is not yet dry, the adhesive 10 slides in the direction of arrow A, causing an even larger positional shift. Furthermore, in the past, the adhesive 19 was deposited on the side surface of the container 2 due to the displacement of the adhesive 10.
In addition to protruding from the container 2 and deteriorating its appearance, there was also a risk that the adhesive material 10 would come off from the container 2.

Furthermore, the conventional type has a container 2 as shown in FIG.
Even when passing between both guide belts 17e, 13e and escaping, both belts 17e, 13e
As the container 2 passing through is suddenly released from its pinched state and restored to its original shape, the adhesive 10 attached to the container 2 is repositioned in the direction of arrow B, which is the opposite direction from the previous time. This resulted in misalignment, which caused a serious problem in the reliability of the adhesive.

Therefore, the present invention was devised in view of the above-mentioned conventional problems, and its purpose is to solve the problem even when attaching an attached object such as a straw package to a flexible container. The object of the present invention is to accurately and reliably adhere the adhesive material to the appropriate side surface position of the container without causing any displacement due to slippage or the like of the adhesive material.

(Means for solving the problem) The present invention does not sandwich the container between two guide belts that are always provided in a fixed position and press it against the suction drum, as in the past, but instead of pressing the container against the suction drum. The above-mentioned conventional problems are attempted to be solved by forcibly pressing the container against the suction drum side only when the container is transferred to face the adhered material on the side.

That is, in the present invention, of the guide belts 17 and 13 for guiding the transfer of the containers 2 provided on one side and the other side of the conveyor 1 where the suction drum 3 is arranged, a belt is placed on the side facing the suction drum 3. When the container 2 is transferred to a position facing the adhesive 10 adsorbed on the suction drum 3, the container 2 is attached to the back side of the guide belt 13 provided on the suction drum 3 side via the guide belt 13. A pushing body 1 that pushes and projects the guide belt 13 to bring it into pressure contact with the kimono 10
This is a device for attaching an attached object such as a straw package to a container, which is provided with a reciprocating unit 5.

(Function) In the pasting device characterized by the above configuration, when the container 2 conveyed on the conveyor 1 faces the pasted object 10 on the suction drum 3, the pushing body 15 is actuated to move the guide belt 13. When the container 2 is a soft packaging bag or the like that is easily deformed, the guide belt 13 can push the container 2 into contact with the adhered object 10 on the suction drum 3 side by pushing it out. Even if it is, the container 2 and the object 10 can be firmly contacted, and the adhesion work can be carried out reliably. Therefore, the guide belts 17 and 13 for guiding and transporting the container 2 do not need to be set to narrow dimensions so as to pinch the container 2 from both sides with strong force, and the container 2 to which the adhesive material 10 is attached is This can suitably avoid causing undue deformation of the adhered object 10 that may cause it to shift when passing between the guide belts 17 and 13.

In addition, since the container 2 is pressed toward the suction drum 3 via one of the guide belts 13 for guiding the transfer of the container 2, the container 2 is moved by the pushing body 15.
The container 2 is more reliably pressed when pressed, and there is no risk of the container 2 falling over.

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

In FIG. 1, 1 indicates a conveyor on which containers 2 are placed and conveyed. 3 is the outer peripheral surface 2 as shown in Figure 3.
A third suction drum is provided on one side of the conveyor 1 and is equipped with a large number of holes 4 for exerting a suction action. Further, on the other side of the third suction drum 3, there is a second suction drum 5 which has suction holes on the outer peripheral surface, and a recess 6 formed on the outer peripheral surface as shown in FIG.
A straw package in which first suction drums 8 each having a suction hole 7 formed at the bottom thereof are arranged side by side, and continuous straw bodies 9 (already known) to be supplied to the first suction drums 8 are separated individually. 10 can be adsorbed and transferred to the third suction drum 3 via the second suction drum 5. In addition, the suction drums 3, 5, 8
perform synchronized intermittent rotation operations.

Reference numeral 11 denotes a reciprocating cutter for individually cutting the continuous straw packages 9 supplied to the first suction drum 8 into straw packages 10. Reference numeral 12 designates a hot melt gun installed on the side of the third suction drum 3 for injecting and applying adhesive 19 to the adhesive surface of the straw package 10 that is attracted and transferred by the third suction drum 3. belongs to.

Reference numeral 13 denotes a guide belt made of a flat belt that is circulated and driven with a plurality of guide rollers 14 disposed on the other side of the conveyor 1 opposite to the suction drum 3. The guide belt 13 is connected to the side surface 20a of the container 2 They are provided so as to face each other, and the distance L from the third suction drum 3 is set to be wider than the sum of the thickness widths of the container 2 and the straw packaging body 10.

15, the guide belt 1 is attached to the third suction drum 3;
A flat pushing body provided on the back side of the guide belt 13 so as to face each other through the guide belt 15.
A reciprocating cylinder 16 is connected to the rear part of the guide belt 13 so that the guide belt 13 can be projected toward the third suction drum 3 by pushing the pushing body 15 . Reference numerals 17 and 17 designate guide belts made of V-belts that are driven and run in two positions, upper and lower, from the front surface of the third suction drum 3 forward in the direction of conveyance, as shown in FIG. It is provided. Reference numerals 18 and 18a respectively indicate seat guide belts 18 which are round belts running at low positions along both side edges of the conveyor 1.

The present embodiment has the above configuration, and an example of its use will be described next.

First, a container 2 formed as a flexible, so-called self-supporting packaging bag is conveyed by a conveyor 1 and transferred to the front side of a third suction drum 3. A continuous straw package 9 is supplied to the drum 8, cut into individual straw packages 10 by a cutter 11, and then transferred to the third suction drum 3 via the second suction drum 5.
Move it to the front position. Incidentally, while the third suction drum 3 is being transferred, an adhesive 19 is applied to the back surface thereof using a hot melt gun 12.

Thereafter, in a state where the container 2 is transferred to a position facing the straw packaging body 10 in the front position of the third suction drum 3, the cylinder 1 is moved as shown in FIG.
6 to push the container 2 toward the suction drum 3 via the guide belt 13 by the pusher 15, the straw package 10 can be firmly attached to the side surface 20 of the container 2 without shifting. It will be worn. Also,
After that, when the pushing body 15 is moved backward, the container 2 is moved by driving the conveyor 1 and both guide belts 13, 17,
It is transported to the next process in a state where it is prevented from falling by guides 17.

Therefore, the container 2 that has been transported through such a process and has the straw packaging body 10 attached thereto will be a proper container in which the straw packaging body 10 will not be displaced at all on its side surface 20, as shown in FIG.

Incidentally, in the above embodiment, explanation regarding the timing control means for the reciprocating motion of the pushing body 15 is omitted, but this timing is synchronized with the conveyance timing of the container 2 of the conveyor 1 and the rotational transfer operation of the suction drum 3, etc. It can be easily set.

The present invention does not require any specific means for controlling the operation of the pushing body 15, and the specific shape of the pushing body 15 and the means for operating the pushing body 15 are not limited to the use of a reciprocating cylinder, but may also be used in various ways. methods are applicable.

Furthermore, the design of the present invention can be modified as shown in FIG. 7, for example, as a means of improving the efficiency of attaching objects to containers. In the same conveyor 1, two suction drums 3a, 3b and pushing bodies 15a, 15b are installed facing each other, and containers with unattached objects on the front suction drum 3b side are installed in the same conveyor 1. By supplying the two containers 2, each of the two suction drums 3a and 3b
It is possible to perform the pasting work on each at the same time, doubling the work efficiency.

Furthermore, in the present invention, instead of arranging a plurality of suction drums in parallel as in the above embodiment, the first and second suction drums are removed, and only the suction drum 3 is provided on the side of the conveyor. There is no problem even if the straw package 10 is directly supplied to the drum 3. Furthermore, the means for applying the adhesive 19 to the object 10 is not limited to the hot melt gun as described above, and the adhesive may not be applied to the object but may be applied to the other container side. Furthermore, the type of adhesive does not matter.

In addition, the present invention allows the specific configuration of each part, such as the specific arrangement of the guide belts 13 and 17 for guiding the transfer of containers, the specific type of the conveyor 1, etc., to be freely selected within the scope of the present invention. The design can be changed freely, and although the straw package and the attached object are indicated by the same reference numerals in the text for convenience, the types of the attached object and the container to which the present invention is applied are by no means limited to those of the above embodiments.

(Effects of the invention) As described above, the invention includes a pushing body that is reciprocably provided on the back side of the guide belt for the container transfer guide, which faces the suction drum that transfers the adhered material, so that it can be moved on the conveyor. Since the structure is such that when the conveyed container and the adhered object face each other, the container can be pushed into contact with the adhered object side of the suction drum, the guide belt and the suction drum are not connected as in the past. There is no need to always set the interval narrowly and press the container against the suction drum, and the container can be transferred without being deformed at a certain distance from the suction drum, allowing reliable adhesion work. Summer.

As a result, the present invention can completely prevent slipping and misalignment of the attached object, which occurs due to deformation during container transfer, and even when the container is a soft packaging bag, etc. It has achieved the special effect of being able to reliably attach the adhesive to a predetermined side surface position, preventing inappropriate extrusion of the adhesive, and producing a container with an adhesive that has a good appearance and high commercial value. .

Furthermore, in the present invention, when the container is pushed toward the suction drum side by the pushing body, the container is pushed through a guide belt that guides the transfer of the container. The container can be properly clamped on both sides by guide belts to prevent the container from tipping over, and the container can be pressed securely, which is highly practical.

In addition, since the present invention has a configuration in which a pushing body is provided on the back side of one of the guide belts so as to be able to move back and forth, a conventional complicated mechanism such as a swinging lever that takes out the adhered material from the suction drum side and transfers it to the container side is required. The device configuration is simple, and manufacturing and maintenance are easy.
