Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solution applying apparatus for applying a solution to the surface of a bottle such as a glass bottle.

[0002]

2. Description of the Related Art As an apparatus for applying a solution to the surface of a bottle, a bottle suspended from a pallet is immersed in a solution storage tank so that the solution overflows as the pallet is lowered by lifting means. There is a so-called dipping solution coating apparatus which coats the bottle surface at the overflow level.

According to this coating apparatus, since the solution overflows, the upper edge of the coating of the solution on the bottle surface, that is, the parting line of the solution becomes clear, and therefore, a good-looking finished solution coating is achieved. Although,
In the above-described coating technique by immersion of the bottle, the bottle held suspended is simply lowered and immersed in the solution storage tank. Therefore, with the immersion, as shown in FIG. The air existing in the dent j at the bottom of the tank rises and becomes bubbles, and a solution layer S containing many bubbles is generated at the surface layer portion of the solution in the tank 152.

[0004] Since these air bubbles lead to poor coating, conventionally, a solution equivalent to the volume of the solution containing the air bubbles is supplied to the solution storage tank 152, and the solution layer S containing the air bubbles is eliminated by overflow. In order to clarify the parting line m of the solution with respect to the bottle surface, a certain volume of the solution was further supplied to the tank 152, and the solution was applied to the bottle surface at the overflow level.

[0005]

However, in addition to eliminating the solution layer S containing air bubbles from overflowing, it is necessary to apply the solution to the bottle surface at the overflow level.
Since a considerable amount of solution needs to be replenished, which takes a long time, there is a problem in that not only the productivity is reduced but also the amount of the overflowed solution is large.

Further, since the air existing in the depression j at the bottom of the bottle does not completely escape from the depression j, a coating failure occurs on the coating film at the bottom of the bottle due to the remaining air. Problems remained.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances, and is not limited to the formation of air bubbles existing in the depressions at the bottom of the bottle, but also the coating failure due to a part of the air remaining at the bottom of the bottle. An object of the invention is to provide a revolutionary bottle immersion coating technique that is reliably prevented.

[0008]

The technical means adopted by the present invention to achieve the above object are as follows. That is, the present invention provides the above-described bottle dipping solution coating apparatus, wherein the pallet is in a first state in which the bottle bottom is inclined with respect to the solution surface until the suspended bottle bottom is immersed in the solution. After the bottom of the bottle is immersed in the solution, the posture is changed to a second state in which the bottle is returned to the solution coating posture of the overflow level.

According to the above configuration, when the pallet is changed to the first state and lowered, the bottom surface of the bottle is inclined with respect to the solution surface and immersed in the solution. The air present in the depression at the bottom will be naturally eliminated.

Therefore, it is possible to surely prevent the coating failure due to the air remaining at the bottom of the bottle, and to prevent the solution layer containing the bubbles from being formed on the surface layer of the solution. In other words, productivity can be increased by shortening the coating time.

After the bottom of the bottle is immersed in the solution, the pallet is repositioned to the second state, and the necessary amount of solution for clarifying the parting line is supplied to the solution storage tank, thereby causing the overflow. In a short time with a small amount of the solution, a good-looking finished solution coating with a clear parting line can be achieved.

The transfer pitch of the pallet 7 is specifically, as shown in FIGS.
, A solution application position G on the bottle surface, a solution exclusion position for omitting the excess solution on the bottle surface by its own weight, an exclusion position for forcibly removing the excess solution, and a pallet conveyance by the pallet discharge means 25. The pallet transfer guides 81 each having a roller are disposed at positions other than the pallet transfer position.

When the suspended holding bottle 3 is immersed in the solution storage tank 23 in the simple suspended posture, the air existing in the depression at the bottom of the bottle rises with the immersion, and the air is bubbled. As described above, a solution layer containing air bubbles is formed on the surface layer portion of the solution No. 1 to cause coating failure.

In addition, the air existing in the depression j at the bottom of the bottle does not completely escape from the depression j, and due to the remaining air, coating failure may occur on the coating film at the bottom of the bottle. As described above.

Therefore, in the present invention, the pallet 7 is integrated with the pallet transfer guide 81 arranged at the solution coating position G so as to be detachable, and the guide 81 is provided so as to be tiltable and ascendable and descendable. Until the bottom is immersed in the solution, the pallet 7 with the bottle 3 suspended and held
Is switched to the first state X in the inclined posture, so that air existing in the depression j at the bottom of the bottle is naturally removed, and
After the bottom of the bottle is immersed in the solution, the position of the pallet 7 is changed to the second state Y so that the bottle 3 returns to the original suspended position, and the solution is applied to the bottle surface at the overflow level. Make up.

That is, as shown in FIGS. 10 to 16, the movable bases 84, 84, which can be raised and lowered via the synchronously driven lifting and lowering means 83, are moved from the pallet introduction position H by the second traverse means 21 to the solution. The pallet 7 carried in the coating position G is disposed so as to face the longitudinal direction of the pallet 7, and the tilting base 86 is pivotally mounted on each movable base 84 so as to be rotatable around a support shaft 85 along the longitudinal direction of the pallet 7. The tilt base 86 is provided with a plurality of guide rollers 87.

13 and 16, the cylinder rods 89 of both rod cylinders 88 are oriented in the width direction of the pallet 7, and both ends of the rods are fixed on the movable base 84. Between the guide rails 91 via the locking means 90a.
Along with a cylinder tube 90, a block 92 is provided, and a roller 93 is connected to the block 92, and a pair of guide rails 9 sandwiching the roller 93 is provided.
4 and 94 are provided on the tilting base 86 in the vertical direction. The pallet 7 is raised and lowered as the movable bases 84 and 84 are raised and lowered by the raising and lowering means 83, and the cylinder tube 90 is reciprocated. And tilting base 8
6 and thus the pallet 7 is reciprocated about the support shaft 85.

Further, both rod cylinders 96 are arranged above the cylinder tube 90 with the cylinder rod 95 directed in the longitudinal direction of the pallet 7.
The slide member 98 is connected to the cylinder tube 97 of the pallet 7, and two engaging holes (see FIG. 6) 99, 99 are formed in the reinforcing member 43 provided on the transport handle 42 of the pallet 7, and Pins 100 that can be disengaged from the locking holes 99, 99,
When the base 100 is tilted by connecting the slide 100 to the slide member 98, the pins 100, 100 are engaged with the locking holes 99, 99, and the pallet 7 is moved to the tilting base 86 by the pin locking. Integrate the base 86
Is configured to prevent the pallet 7 from falling due to the tilt of the pallet.

In the above configuration, as shown in FIG. 13, during the intermittent transfer stop of the pallet 7 by the second traverse means 21, the pallet 7 is pin-locked to the tilting base 86, and the base 86 is connected to the tilting base 86. When the pallet 7 and the hanging bottle 3 are tilted and the posture of the hanging bottle 3 is changed to the first state X, and the pallet 7 is immersed in the solution in the solution storage tank 23 by the lifting / lowering means 83, the pallet 7 remains in the depression j at the bottom of the bottle. By naturally removing the air, no air bubbles leading to poor coating are formed on the surface of the solution.

Then, after the bottom of the bottle is immersed in the solution, the pallet 7 is changed to the second state Y so that the bottle 3 returns to the original solution coating posture, and the bottle mouth 3a is coated with the solution. While the tank is positioned at the level L, the volume of the solution necessary for clarifying the parting line m is supplied to the tank 23, and then the bottle 3 is pulled up from the solution storage tank 23 so that the parting line m of the solution is obtained. A clear, good-looking solution coating is achieved.

Although not shown, the guide body 81 disposed at the above-described position where the solution is removed by its own weight and at the position where the solution is forcibly removed is fixedly arranged so as to be tiltable only. Then, the bottle 3 is inclined so that the excess solution of the coating on the bottle surface is gathered by its own weight at the inclined lower end at the bottom of the bottle, and this is dropped and collected in the guide pan 82. At the exclusion position, for example, a plate-like member such as stainless steel or felt is provided at the bottom of the bottle so as to be capable of coming into contact with and separating from the bottom, and the plate-like member is brought into contact with the solution that has not been dripped by its own weight. The solution that has not been dripped completely is forcibly eliminated by transferring the solution.

As described above, the pallet 7 is moved to the first state X.
By changing the posture to the second state Y and immersing the bottle 3 in the solution storage tank 23, coating defects caused by air bubbles are effectively eliminated. When 3 is pulled out of the solution storage tank 23, there is a concern that excess solution n may drop from the surface of the bottle and a solution layer S containing bubbles may be generated on the surface layer of the solution. As preferred above, the solution coating means 111 is configured as follows.

The solution storage tank 23 is provided with a fixed tank 113 for overflowing the solution at a level lower than the solution application level L due to overflow, and a position changeable up and down with respect to the fixed tank 113 and with the vertical movement. A movable tank 114 capable of changing the solution level is provided so that the overflow of the solution layer S containing bubbles can be eliminated in a short time by making the amount of the overflow solution small.

More specifically, the fixed tank 113 is a bottomed tank whose upper edge is almost the same height as the solution coating level L and whose plan view is rectangular. In order to prevent stagnation, triangular corner members 115 are provided on the inner surfaces of the four corners of the tank, and rising plates 116, 116 between the corner members 115, 115
Notches 117a and 117 for overflowing the solution
b is formed.

The overflow level L1 of the notches 117a and 117b is determined by the solution layer S containing bubbles in the upper layer of the solution.
And the maximum solution storage level by the movable tank 114 (that is, the solution coating level) corresponding to the height corresponding to the total volume of the solution volume of the solution and the maximum bottle volume to be coated by the solution coating device 20. L) is set lower.

On the other hand, the movable tank 114 is provided with four shutters 118a and 118b for individually closing the cutouts 117a and 117b so as to be vertically movable, and the shutters 118a and 118b can be moved at once. Elevating means 119 for changing the position is provided.

More specifically, a pair of upper and lower shutter holding bars 121, 121 are placed on the lifting bases 120, 120, which are raised and lowered synchronously by the lifting / lowering means 119, with the notches 117a, 117a on both sides in the width direction of the pallet 7 facing each other.
While the shutter 118a that closes the notches 117a on both sides in the width direction of the pallet 7 is
Bent plate portions 122 extending between the bars 121, 121 are connected to both side edges, and projections i, i contacting the bars 121, 121 at one point are formed at the upper and lower edges, and the pallet 7 is cut on both sides in the longitudinal direction. Shutter 118b to close notch 117b
With respect to the above-mentioned bars 121, the extension plates 123 which enter between the bars 121, 121 are continuously provided on both sides in the longitudinal direction.
A holder 124 sandwiched by 121 is held.

Then, a plate-like member 126 is slidably connected to the shutter 118a via, for example, a bolt 125.
And a spring 127 for urging and abutting the shutter 118a against the rising plate portion 116 is interposed between the plate member 126 and the shutter 118a, and adjusting the urging force of the spring 127. A push bolt 128 for holding is held by the bars 121, 121.

In the solution coating apparatus 20 having the above-described structure, at the solution coating position G, the pallet 7 is integrated with the tilting base 86 by the locking of the pin while the intermittent transfer of the pallet 7 by the second traverse means 21 is stopped. This base 8
6, the pallet 7 and, consequently, the hanging bottle 3 are changed into the tilted first state X, and the pallet 7 is lowered by the lifting / lowering means 83, so that the bottom of the hanging bottle 3 is immersed in the solution. At this time (see FIG. 21 (A)), the posture of the bottle 3 is changed to the second state Y which is the solution coating posture of the overflow level (see FIG. 21 (B)).
Is done.

Then, the pallet 7 is changed to the first state X, and the bottom of the bottle is immersed in the solution while the bottom of the bottle is inclined with respect to the surface of the solution. The existing air is naturally eliminated, so that not only the solution layer containing bubbles is not formed on the surface portion of the solution, but also a problem that a part of the air remains in the depression j does not occur.

Next, as shown in FIG.
The pallet 7 whose posture has been changed to the state Y is immersed in the solution storage tank 23 so that the bottle mouth 3a is positioned at the solution application level L, that is, the solution overflows, and the parting line m is formed. The volume of solution required for clarity is replenished to the tank 23, after which FIG.
As shown in (D), the pallet 7 is placed in the solution storage tank 23.
Since the solution is applied to the bottle surface at the overflow level, the solution application with a clear finish line m of the solution and a good-looking finish is achieved.

At this time, by changing and setting the upper limit position of the movable tank 114, that is, by changing the overflow level of the solution, or by changing the immersion dimension of the bottle 3, the position of the parting line m is changed. It can be easily changed and set.

When the bottle 3 is pulled up after the solution application, there is a concern that a solution layer S containing bubbles may be generated on the surface layer of the solution due to the dripping of the excess solution n from the bottle surface.
In addition, by raising the solution coating bottle 3, the solution level in the tank is reduced by the volume of the bottle 3,
Here, as shown in FIG. 21 (D), by lowering the movable tank 114, the solution layer S including the bubbles is notched 1
The solution layer S containing air bubbles is removed by overflowing through the solution storage tank 23 by reducing the amount of the overflow solution without having to replenish the solution storage tank 23 with the solution. Can be eliminated.

Thereafter, as shown in FIG. 21 (E), the movable tank 114 is returned to the original position, and the solution corresponding to the bottle capacity is supplied to the tank 23, and the solution coating of the next bottle 3 is performed. In this case as well, since it is not necessary to replenish the solution storage tank 23 with the solution, the productivity can be increased by shortening the solution application time as a whole.

It should be noted that reference numeral 131 in FIG.
This is a capacity reducing member for limiting the amount of the solution contained in the bottle 3 to a necessary minimum. As shown in FIG. 13 and FIG. I have.

Reference numeral 132 in the figure denotes a partition member disposed on the upper side between the adjacent solution storage tanks 23, 23.
This is to prevent the overflowed solution from flowing into the solution storage tanks 23 adjacent to each other when the solution is applied to the bottle surface at the overflow level.

That is, the adjacent solution storage tanks 23, 23
When the solution flows into the container, there is a concern that the solution coating level L may wave and the parting line m may be disturbed. Therefore, in order to prevent such a situation, the solution is prevented from flowing. It is.

As described above, according to the present invention, when the bottle is immersed in the solution storage tank, it is reasonable to change the pallet holding and suspending the bottle to the first and second states. The improved technique ensures that air present in the depression at the bottom of the bottle is eliminated.

Accordingly, not only the coating failure due to the air remaining at the bottom of the bottle is prevented, but also the solution layer containing bubbles is not formed on the surface layer of the solution. In addition, productivity can be improved by shortening the coating time, and the amount of the overflow solution is made small, and in a short time, a good-looking finish solution coating with a clear parting line is achieved. .
