Description

[Detailed description of the invention] ``Industrial Application Field'' This invention relates to the improvement of container cleaning machines, and is particularly concerned with the improvement of container cleaning machines, especially containers with small diameters and deep shapes (specifically, containers with small diameter bottles and the container-like bodies of felt pens). The present invention relates to an improvement of a container washer suitable for cleaning containers, etc.

``Prior Art'' Conventionally, this type of cleaning equipment has been constructed by installing a large number of pipes that spray cleaning water upward and erecting them side by side on an endless conveyor, placing containers over these pipes with their mouths facing downwards, and It is generally put into practical use that cleaning is carried out by spraying cleaning water into the container from the pipe while the container is being conveyed by the endless conveyor.

``Problems to be Solved by the Invention'' However, this type of conventional cleaning device requires a very long conveyance path if a large number of containers are to be cleaned in a short period of time. However, it still has the disadvantage of requiring a large amount of space.

In addition, drying is required after normal cleaning, and cleaning itself generally involves a combination of chemical cleaning and fresh water cleaning to wash off the chemical.Recently, longer transport paths are required to meet these demands. There is a tendency to

The present invention was developed in view of the above, and aims to provide a container cleaning device that occupies less space and can easily handle complex cleaning and drying processes. be.

``Means for Solving the Problems'' In line with the above purpose, the structure of the present invention, which is summarized in the scope of the above-mentioned utility model registration claims, is to solve the above-mentioned problems by cleaning by adding a predetermined amount of cleaning water C. Tank A
Inside, guide wheels S1, S2, S3 such as sprockets
Enter the cleaning tank A from the upper position guided by ..., advance on the sloped surface so that the upper part is located on the back side and the lower part is located on the front side when viewed from the front, and the cleaning water C
A conveyance path 30 consisting of a chain loop or the like exits from the upper part of the cleaning tank A after passing through the interior of the cleaning tank A. Container holders 40 shaped like the above are arranged at predetermined intervals, and the hollow portions 41 of each of the container holders 40 communicate with the back side of the conveyance path 30. is the hollow part 41 of the container holder 40
A technical measure is taken in which a nozzle 50 is arranged to spray cleaning water toward the water.

``Operation'' Therefore, the present invention rotates the conveyance path 30, and attaches the container M to the container holder 40 arranged in parallel with the conveyance path 30.
are sequentially loaded so that the tip of the container holder 40 is inserted through the opening.

Then, in this state, as shown in FIG. 3, since the tip of the container holder 40 is inclined upward, the loaded container M will not slide down to the inclined lower end side of the container holder 40 due to its own weight. Therefore, the container holder 40 is apparently inserted deep into the container M, and the weight of the container M acts to prevent the container M from falling off from the container holder 40.

In this way, the container holder 40 of the conveyance path 30
The containers M held in the tank A are sequentially carried into the cleaning tank A, and are then immersed in the cleaning water C. At this time, the containers M have their openings facing diagonally downward and the bottoms facing away from the openings. Because it is located above, some air is trapped inside the container M. Therefore, if the cleaning water C is sprayed from the nozzle 50,
Container holder 4 passing in front of this nozzle 50
0 is supplied with cleaning water C, and a jet stream of this cleaning water C is forced into the container M through the hollow part 41, replacing the trapped air, and the cleaning water C flows inside the container M.
It will be filled with.

The injection pressure from the nozzle 50 is set appropriately, but if the injection pressure is strong, part of the cleaning water C filled in the container M will convect within the container M, and the excess will flow out from the opening. However, if the injection pressure is too high, the container M will be blown away against its own weight, and the trapped air acts as a buoyant force, so as a general rule, the container holder should not be The injection pressure of the cleaning water C may be set based on the inclination angle of 40 degrees and the weight of the container M. (However, if the presser body 60 in the embodiment described later is provided, these conditions may be ignored.) In this way, the container M immersed in the cleaning water C is then moved along the conveyance path 30. Along with this, the cleaning water C is taken out in good order, but since the opening of the container M taken out from the cleaning water C is facing downward, the cleaning water C filled therein naturally flows through the opening. However, the container holder 40 inserted into the container M exhibits an outflow promoting effect as the cleaning water C flows out along the container holder 40.

``Example'' Next, an example of the present invention will be described below with reference to FIGS. 1 to 3.

The illustrated example is an example of a container cleaning device that sequentially performs a series of cleaning of containers M with a chemical solution, followed by clean water cleaning, and further drying and cooling. is located diagonally so that the hydrolysis is located on the back side and the hydrolysis is on the front side.

This tank 10 has partitions 13 to 1 in the middle.
9, and from one end (right side in Figure 1) to the other end: cleaning tank A, first liquid draining tank B, second cleaning tank C, second liquid draining tank D, third cleaning tank E, third liquid. It is divided into a cutting tank F, a drying tank G, and a cooling tank H.

Although it is not necessarily clear in the drawings, the partitions 13 to 19 have an opening at the top so that a conveyance path 30, which will be described later, can pass therethrough.

The cleaning tank section A has an inclined back surface 11.
, a side surface 12, a partition 13, a front surface 14 parallel to the back surface 11, and a bottom surface 14'. In the 2nd cleaning tank C and the 3rd cleaning tank D, warm water is used as the cleaning water C) in a predetermined amount, and guide wheels S1 and S of sprockets etc.
2, S3... is guided to the cleaning tank A from the upper position.
A chain loop, etc. enters the inside and advances on an inclined surface so that the upper part is located on the back side and the lower part is located on the front side when viewed from the front, passes through the cleaning water C, and then exits from the upper part of the cleaning tank A. A transport path 30 consisting of the following is housed.

That is, in this embodiment, for convenience of manufacture, the entire rectangular tank 10 is installed obliquely, and guide wheels S1, S2, S3, . The conveyance path 30 guided by the tank 10 itself runs on an inclined surface such that the upper part is located at the back and the lower part is located at the front when viewed from the front. The guide wheels S1, S2, S3, . . . may be placed upright and positioned on a certain slope. In addition, in this embodiment, each of the guide wheels S1, S2, S3... uses a sprocket, and the conveyance path 30 uses a chain loop, but this conveyance path 30 uses a belt, rope, etc. Of course, the guide wheels S1, S2, S3, . . . may be conventionally known ones suitable for the properties of these conveyance paths 30.

Pipe-shaped container holders 40 with their tips facing upward in a direction perpendicular to the traveling direction of the transport path 30 are disposed on the transport path 30 at predetermined intervals, and each of the container holders 40 is The portion 41 communicates with the back side of the conveyance path 30,
Furthermore, a nozzle 50 for spraying cleaning water toward the hollow portion 41 of the container holder 40 is arranged on the back side of the conveyance path 30.

As shown in FIG.
A discharge port of a cleaning water C pumping device (not shown) is connected to the upper end portion which is fixed to 1 and protrudes from the back surface 11. It is desirable to provide a plurality of nozzles 50 along the conveyance path 30, and furthermore, the rear end side of the hollow portion 41 of the container holder 40 (the side facing the nozzle 50) has a tip inner diameter (inner diameter on the side facing the nozzle 50). It is desirable to arrange the flow collecting ports 42 whose diameters gradually become larger.

Note that the conveyance path 30 is the first one after leaving the cleaning tank A.
It enters the liquid draining tank B, and further passes through the above-mentioned second cleaning tank C, second liquid draining tank D, third cleaning tank E, third liquid draining tank F, drying tank part G, cooling tank part H, and then to the cleaning tank A. However, in front of the cleaning tank A, there is a feeding drum 71 for feeding containers M one by one to this conveyance path 30, and after the cooling tank section H, there is a feeding drum 71 for taking out the containers M. A chute 72 is provided.

The feeding drum 71 has an appropriate number of grooves arranged parallel to the central axis in which the containers M are housed at predetermined intervals (intervals corresponding to the intervals of the container holders 40) on its circumferential surface, and is conveyed by a conveyor 73 to the chute. 74
The containers M dropped from the container M are stored one by one in the groove and taken out.
An extrusion device (mechanically reciprocating lever, cylinder, compressed air injection, etc.) disposed on one end side of the feeding drum 71 is placed at a position where the container M taken out from the circumferential surface of the drum 71 fits. (not shown since it is conventionally known) is used to push out the bottom of the container M or the container M itself, and the containers M are sequentially loaded into the container holder 40 located at the appropriate position.

Further, the take-out chute 72 is an extrusion device having the same structure as the extrusion device described above, and is used to remove containers M from the container holders 40 in sequence when each container holder 40 on the conveyance path 30 advances to a predetermined position. It is adapted to be received and conveyed onto a conveyor 75.

Further, in this embodiment, a presser body 60 shown in FIG. 3 is housed in the cleaning tank A. This presser body 60 is composed of a chain loop guided by sprockets S'1, S'2, etc. arranged parallel to the conveyance path 30, and the water is sprayed from the nozzle 50 and passes through the hollow part 41 into the container M. Cleaning water C sprayed onto
The injection pressure is large to prevent the container M from being blown off and falling off by receiving the bottom surface of the container M when it moves. In addition, in Figure 3, 61
is a rolling surface that rotates the container M, and is not stored in the cleaning tank A, but is stored in a first liquid draining tank B, a second liquid draining tank D, or a third liquid draining tank F, which will be described later.
This rolling surface 61 is arranged parallel to the conveyance path 30, and the container M rolls by moving while touching the peripheral surface of this rolling surface 61, and the cleaning water C accumulated in the container M The liquid is ensured to flow out into the first liquid drain tank B, the second liquid drain tank D, and the third liquid drain tank F.

In this embodiment, the container M that has left the cleaning tank A enters the first liquid draining tank B.
Inside the liquid draining tank B, the extension of the conveyance path 30 runs on the same surface as inside the cleaning tank A, which is inclined so that the upper part is located on the back side and the lower part is located on the front side when viewed from the front. (The conveyance path 30 extended below also advances on the same plane). Since the cleaning water C is not put into the first liquid draining tank B, the cleaning water C filled in the container M loaded in the container holder 40 with the opening facing downward is One liquid will flow out and fall into the draining tank B, but at this time, the container holder 40 inserted into the container M will guide the outflow of the cleaning water C and hasten the outflow. By providing the rolling surface 61, it is also possible to prevent the cleaning water C from remaining in the neck of the container M or the like.
Further, the above-mentioned nozzle 50 is also provided in this first liquid draining tank B, and when air is injected from this nozzle 50 instead of cleaning water C, the cleaning water C remaining in the container M can be blown out. It is possible.

Furthermore, in this embodiment, the container M that has exited the first liquid draining tank B enters the second cleaning tank C, and this second cleaning tank C has the same structure as the cleaning tank A. However, in this second cleaning tank C, warm water obtained by heating clean water is used instead of using a chemical solution. And this second
After leaving the cleaning tank C, the container M passes through a second drainage tank D, which has the same structure as the first drainage tank B, and a third cleaning tank E, which has the same structure as the cleaning tank A, and then to the third drainage tank F. It is made to progress. The rolling surface 61 and the nozzle 50 for injecting air are connected to the first drain tank B and the second drain tank B.
Although it may be provided in both the liquid draining tank C and the third liquid draining tank D, since the cleaning water C can be easily removed in the next stage in the first liquid draining tank B and the second liquid draining tank C, It is particularly effective to place it in this third liquid draining tank D.
If the washing water C is sufficiently drained here, the drying efficiency in the next drying tank G can be increased.

Further, the container M that has exited the third liquid draining tank D enters the drying tank G next. Drying air heated by a heating device 81 is supplied to this drying tank G.
The cleaning water C adhering to the container M is dried by passing through the drying tank G. In this embodiment, the container M is finally cooled by passing through the cooling tank H, and it is preferable to supply cold air to the cooling tank H.

In addition, in the figure, 29a to 29h indicate valves, which are for taking out the cleaning water C, train, and exhaust flow from the lower part of each tank.

[Effects of the invention] As described above, the present invention can provide a container cleaning device in which the conveyance path 30 is installed obliquely, so that the area occupied by the entire device can be reduced by an amount corresponding to the angle of inclination. be.

Since the conveyance path 30 is inclined and the container holder 40 is disposed on the conveyance path 30 in a direction perpendicular to the direction of movement of the conveyance path 30, the container holder 40 is inclined with its tip facing upward. As a result, the container M loaded into the container holder 40 is pushed into the depth of the container M by its own weight, and the container M can be held without any special holding mechanism and without fear of falling out. It is possible to provide a container cleaning device that can be held and transported and has a simple configuration.

Furthermore, the present invention has a hollow part 41 disposed in the container holder 40, and a nozzle 50 for spraying the cleaning water C toward the hollow part 41, thereby holding the container M with the opening facing downward. To provide a container cleaning device capable of expelling air trapped in the container M when the container M is immersed in the cleaning water C, completely filling the container M with the cleaning water C, and performing reliable cleaning. It is something that can be provided.
