Description

  The present invention relates to a laminating apparatus (hereinafter also referred to as a laminator) for laminating a continuous film and film, or a film and a plate material, etc., using various adhesives and using a pair of laminating rollers.

  The laminator for ordinary film and the laminator for laminating a sheet of sheet material and film have a single purpose of use, so the material of the pair of laminating rollers to be bonded is determined, and you want to bond the other The case also had to get the laminator that was there.

  When the two members are bonded together, the selection of the material of the pressure roller becomes a problem due to the difference in hardness between the two members, and the result of the bonding depends on the material of the roller.

  Usually, when laminating or laminating a film, or a film and a plate material, the same product is often produced in large quantities in one production process, so it can be made exclusively by one apparatus.

Moreover, the roller of the laminator laminating part is usually composed of a pair of two rollers, and can be subjected to crimping, opening and rotating, rotating, and heating as necessary.
However, in recent years, not only mass production but also small and multi-product production has been on the rise to meet customer needs.

  In that case, it was dealt with by changing the pasting conditions of the pasting machine used for mass production, but the defect rate was high and it was often not profitable. Finally, there is a problem that the cost increases and the productivity deteriorates by newly replacing a bonding machine that meets the conditions for small-scale production.

In addition, there was a device that can be replaced according to the conditions of the member to which only the laminating roller is bonded, but it takes the same effort as replacing the plate roller of the printing press, and adjustment after replacement is very laborious. It was not a big improvement in productivity. Hereinafter, Patent Document 1 and Patent Document 2 are given as examples of conventional laminators.

  In other words, conventionally, when two members are bonded together, the appropriateness of the material of the pressure roller becomes a problem due to the difference in hardness between the two members, and whether or not the two members can be successfully bonded depends on the material of the roller. . Nowadays, the form of small-lot, multi-product production is increasing. In that case, it was dealt with by changing the pasting conditions of the pasting machine used for mass production, but the defect rate was high and it was often not profitable.

  In view of such a problem, the present invention incorporates a unit that can be equipped with a plurality of turret-type rollers each capable of rotating the two pairs of rollers with respect to a conventional laminator. According to this invention, this unit of the turret type of a laminator can be rotated as needed, a desired roller can be selected, a turret can be fixed at the bonding position, and each can be used as a bonding roller.

  Since the center of the turret-shaped roller arrangement is the center of rotation of the unit, a power transmission shaft is provided here via a clutch, and from there, the rotational force is transmitted to each roller via a planetary gear. You can also.

  Furthermore, in the present invention, a heater can be individually provided at the center of each roller, and in this way, any roller can be heated as required.

  The simplest mechanism for pressing and releasing each roller unit is to move the entire roller unit up and down. However, only one roller moves up and down at the position where the desired roller is selected and set as the bonding position. A structure that can perform the releasing operation is more preferable from the viewpoint of time efficiency at the time of roll change.

  According to the present invention, when laminating films or laminating a plate material and a film, the roller unit of the laminating apparatus is rotated, changed to a desired roller, and fixed. It was possible to cope with the bonding medium with a simple operation, and as a result, it became possible to improve the quality of the bonded film and the productivity of the bonding.

  Various things can be selected as a bonding roller of this invention by each combination, such as a film and a film, a film, and a board | plate material. For example, a rubber roller, a metal roller, etc. can be used as an example of a bonding roller. In addition, for example, in the case of rubber, there may be cases where higher rubber hardness is better or lower hardness is better. It is desirable to set a bonding roller that meets the conditions in advance in accordance with the target to be bonded.

  By doing in this way, even if the object of pasting changes, it is only necessary to select and use the most suitable one from a set of preset rollers. This has become possible without introducing new equipment.

  In addition, even in the case of a bonding medium whose bonding conditions are unknown, conventionally, the same apparatus has been used to search for bonding conditions by changing pressure, temperature, and speed. By changing the material at the same time, the bonding conditions could be found accurately and easily.

  As the best mode of the turret type or revolver type roller unit that can be used in the present invention, as shown in FIG. 1, this time, one in which two laminating rollers are arranged can be used. In addition, the bonding roller is not limited to two. In the present invention, two examples will be described below.

  Usually, in the conventional bonding apparatus and laminator, only one bonding roller is attached to the roller unit. In the present invention, a roller unit capable of setting a plurality of rotatable rollers in this portion is provided.

  In this example, a plurality of pasting rollers are arranged on the same circumference. Here, the driving gears of all the bonding rollers mesh with the gear provided at the rotation center of the unit, and all the bonding rollers rotate at the same time.

  This rotation center gear is intermittently connected by the shaft of the power motor and the clutch, and it can arbitrarily control whether the driving force is applied or not. When used as a free roller, power may be generated by a clutch.

  As a roller arrange | positioned on the same periphery, a metal roller, a rubber roller, the rubber roller from which rubber hardness differs, etc. can assume about two to about four. If too many kinds of rollers are arranged, this unit will become large and it will be difficult to make a film pass, and it may also cause problems, so at most about four are desirable.

  All the individual rollers arranged in this rotatable turret type roller unit can be rotated in the manner described above. On the other hand, the entire unit is also rotated around the rotation center of the unit, and when a desired individual roller comes to the bonding position, the unit can be fixed so as not to rotate at that position.

  This operation can be performed automatically by a motor, but it can also be performed manually, such as when not operating frequently.

  Moreover, the heater is provided in each of these bonding rollers, and the temperature adjustment of the bonding roller is possible as needed. There is a way to warm the whole unit with a single heater, but it is inefficient and uneconomical and takes time. For this reason, it is desirable to adjust the temperature for each bonding roller.

  As a driving method for pressure bonding at the time of bonding, a method in which the entire unit is moved up and down to pressurize, or a roller selected as a bonding roller is provided on the bonding portion separately from the unit, and the bonding roller is the bonding portion. There is a method for applying a pressure driving operation to the roller only when the roller is set to. There is an advantage that the former method is simple. On the other hand, the latter method is advantageous in terms of efficiency.

  Two sets of roller units having such a structure, usually a pair of upper and lower rollers, are arranged as a lower pressure roller and an upper pressure roller, respectively.

  In many cases, the lower pressure roller does not move up and down and is fixed in position on the pass line of the film or plate. In the present invention, the present invention is not limited to this, and a configuration in which only the lower side is movable and a configuration in which the upper and lower sides are movable are conceivable.

The Example of the bonding apparatus which can respond to both a film and a film and a film and a board | plate material using this turret type bonding roller below is shown.
In FIG. 1, the detail of the rotation-selection-type bonding roller unit used for this bonding apparatus is shown. In this example, a roller incorporating a metal roller and a rubber roller having a roller surface made of rubber as a bonding roller is shown.

  In FIG. 1, a metal roller 2 and a rubber roller 3 are supported on two side plates (one side omitted) of the roller unit indicated by 1 in a rotatable state together with gears 4 and 5, respectively.

  At the center of rotation of the unit, there is a gear 6 that transmits the power from the motor. The power of the gear 6 is transmitted to the laminating rollers via the idle gear 7.

  The idle gear 7 is supported in a swingable state by swinging arms 8 and 9 from the center axis and the bonding roller shaft, respectively.

  With this structure, even if the laminating roller moves up and down for pressure bonding, the oscillating idle gear 7 can transmit the power from the central axis to each roller.

  Further, the gear 6 at the center of the unit can be used to interrupt the power from the motor by the clutch 10, and can be used as a free roller when the power is cut off.

  Next, the pressure bonding operation at the time of bonding is performed. When the roller is retracted without performing the normal bonding operation, the swing arms 8 and 9 and the idle gear 7 are pulled by the tension spring 13 of FIG. The laminating roller is within the unit turning radius.

  When performing the bonding operation, when the tip of the air cylinder 11 installed outside this turning radius protrudes to the position 12, and when the force is applied to the swing arm and the idle gear in the direction opposite to the tension spring, The laminating roller protrudes from the outer periphery of the unit in the radial direction and performs the pressure bonding process.

  Next, the example of the multipurpose laminator using the said bonding roller unit is shown in FIG. This corresponds to several types of films and films with adhesives (adhesives), or films with adhesives (adhesives) and plate materials using a pair of the pasting roller units and replacing the laminating rollers with metal or rubber. It is a device that can be laminated and bonded.

  As two types of films, a film 21 with an adhesive and a film 22 without an adhesive are unwound and set in two places. The traveling direction of the film or the like is from the left to the right in the figure.

  First, the film 21 with adhesive is peeled off by the protective film winding of 23 and the adhesive surface is exposed, and is transported to the pasting part as it is and pasted with the film that has been transported in the lower path. , 26 are wound around 27 winding portions via the conveying rollers.

  Next, in the case of a film and a plate material, the adhesive-attached film at the upper part of the path remains as it is, but there is no lower film path, and instead, the plate material is conveyed on 28 conveying rollers.

  When this plate material reaches the bonding unit, although not shown, the film is stuck from the tip of the plate material by pressing the bonding roller at an appropriate timing using a sensor or a timer.
