Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a corrugator gluing machine structure having a movable gluing machine structure.

Generally, as shown in FIG. 1, a corrugator 1 is equipped with a gluing machine 2 for gluing a group of single-sided corrugated cardboards sent out, and a double facer 3 for the next process. An appropriate gap δ is formed between the holes. This gap δ is necessary for workers to enter between the gluing machine 2 and the double facer 3 during setup work and maintenance inspections before starting operation. The glue applied in the machine 2 changes before it enters the double facer 3, causing defects that make the bonding unsatisfactory.

That is, the corrugator 1 includes single facers 7 and 8 for feeding single-sided corrugated cardboard such as the A flute 4 and the B flute 5, a preheater 10 for preheating the liner 6 fed from the mill roll stand 9, the gluing machine 2, and Double facer 3 etc. are installed.

The A-flute 4, which is made of single-sided corrugated cardboard, is made by gluing a liner 4a and a core 4b, and also has a liner 5.
The height of the step of the core is higher than that of the B flute 5 in which the core 5b and the core 5b are glued together. To polymerize A flute 4, B flute 5, and liner 6 to make double-sided corrugated board, glue machine 2 is used to polymerize A flute 4, B flute 5, and liner 6.
Glue is transferred to the top of the step a, and this is heated and pressed together with the liner 6 in the double facer 3 in the next step.

Gluing in the gluing machine 2 is carried out using an applicator roll 12 that rotates while partially immersed in a container in which the glue 11 is stored, a doctor roll 13 that adjusts the amount of glue transferred, and a rider that adjusts gaps, prevents vibrations, etc. This is done by a roll 14 or the like.

The size material 11 is formed from water, raw starch, and a carrier made by swelling this with caustic soda, and the size material 11 is transferred to the step top of the core 4b of the A flute 4, and this is conveyed to the double facer 3, It is adhered to the liner 5a of the flute 5. As shown in FIG. 2, this adhesion is performed by penetrating adhesion 15 between the insert 4b and liner 5a and interfacial adhesion 16 at the boundary thereof. These adhesives are bonded by the effective action of the above-mentioned glue 11, but as mentioned above,
The above gap δ between the gluing machine 2 and double facer 3
Since there is a gap δ in the glued one-sided cardboard
Conventionally, this gap δ was extremely wide when passing through the
Depending on the time it takes to pass through the gap δ, a large amount of water in the paste 11 is absorbed into the filling material 4b or diffused into the atmosphere. Therefore, the remaining percentage of raw starch in the paste 11 increases, resulting in solidification and insufficient adhesion.

On the other hand, as described above, the gap δ is a space required during setup and maintenance, and is required to have a width that allows a worker to pass through.

The present invention was devised to solve the above-mentioned drawbacks, and its purpose is to secure the above-mentioned gap when necessary, and to reduce the above-mentioned gap to zero during operation so that the applicator roll can reach the top of the single-sided corrugated cardboard. To provide a corrugator gluing machine structure which ensures gluing of corrugated cardboard by minimizing the time required until the transposed glue is pressed against paper to be adhered.

In order to achieve the above object, the present invention provides a moving means between the immovable part of the sizing machine and the double facer, and by the moving means, the above sizing machine can be moved to the double facer side. It features a corrugator gluing machine structure that reduces gaps to zero.

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

As shown in FIG. 3, a rotating machine 22 such as a motor is fixed to a base 20 which is an immovable part of the double facer 1. One end of a threaded rod 17 extending in the direction of movement of the cardboard, such as the A-flute 4, is fixed to the rotating machine 22, and the other end is fixed to the double facer 3, which is one of the above-mentioned immovable parts. is supported by A female threaded tool 18 is fixed to the gluing machine 2, and the female threaded tool 18 is screwed into the threaded rod 17.

Further, the pasting machine 2 is slidably mounted on a slide base 21 provided on the base 20.

With the above configuration, when the rotating machine 22 is rotated, the threaded rod 17 rotates at that position. Therefore, the gluing machine 2 can move on the slide base 21 and make the gap δ zero. Of course, by reversing the rotary machine 22, the gluing machine 2 can be returned to its original position.

As described above, when setting up the corrugator 1 and maintaining the glue machine 2, etc., the gap δ can be provided to ensure smooth work, and the gap δ can be set to zero during line operation to reduce moisture in the glue. can prevent the emission of In addition, since the gluing machine 2 is close to the double facer 3, the A flute 4
Although the injection angle becomes steeper, it has been proven that the smoothness of the flow of the A flute 4 is not impaired.

FIG. 4 shows another embodiment.

By operating the pressure cylinder 25 on the base 20, the gap δ can be made zero, and the same effect as in the above embodiment can be achieved.

Although not shown, appropriate buffering means is provided so that the gluing machine 2 does not apply impact force to the double facer.

The movement operation of the gluing machine 2 described above may be carried out manually each time, or may be automatically operated by a control device (not shown) of the corrugator 1.

As described above, according to the corrugator gluing machine structure according to the present invention, during setup work or maintenance inspection before starting operation, the gluing machine is brought close to the double facer, and the gluing machine is used to The glue transferred to the cardboard group can be sent to the double facer before it deteriorates and causes poor bonding. This is particularly effective when operating at high speed to improve operating efficiency and using a fast-drying paste.
