Description

[Detailed description of the invention] "Industrial application field" This invention is used in a container washer that cleans containers by spraying cleaning liquid from above and below while the container is being transported on a conveyor. This invention relates to a horizontal holding guide for holding down both sides of a container to prevent it from moving laterally.

``Problems to be solved by conventional techniques and ideas'' In general, in container washing machines, containers to be cleaned are placed on a conveyor with their openings facing down and are transported, but the bottom side of the conveyor is A direct-injection nozzle that swings in a plane perpendicular to the conveyance direction sprays the cleaning liquid at high pressure intensively to clean the inner surface. Top and side presser guides are provided to prevent it from being blown away.

Conventional horizontal presser guides generally have guide bars fixed to the upper ends of brackets attached to the frames on both sides of the conveyor.
The width of containers to be cleaned differs depending on their contents, so when cleaning containers of various widths, it is necessary to change the mounting position of the guide bar bracket each time. When containers of different widths are to be washed continuously, the worker has to interrupt the washing operation and change the containers each time, which is extremely complicated and requires a lot of effort.

"Means for solving the problems" This invention is intended to solve the above-mentioned problems in the past.
This invention proposes a lateral pressure guide that installs a plurality of oscillating arms on both sides of the running section of a conveyor, with their middle parts attached so as to be freely rotatable in a plane perpendicular to the conveyor, and attaches guide bars, whose tips are bent outward from each other, to the upper ends of adjacent oscillating arms in the forward/rearward direction in a series along the running direction of the conveyor, and attaches balance weights to the lower ends of the oscillating arms.When containers to be washed with different widths are to be continuously washed, the guide bar automatically follows the change in width as the oscillating arms swing, and the rotational moment of the balance weight allows the containers to be washed stably while holding down the sides of the containers without being blown off to the side, making it possible to achieve unmanned and automated cleaning work without the need to change the guide bars as in the past.

"Embodiment" The embodiment of this invention will be described below with reference to the drawings. The container washer 1 is equipped with a shower type washing nozzle 3 above a transport conveyor 2 and a direct injection type oscillating washing nozzle 4 below it, which are freely oscillating in a plane perpendicular to the transport direction of the conveyor 2, and the cleaning liquid sprayed from these nozzles is used to clean the inside and outside surfaces of the containers 5 to be washed, which are transported with their openings facing down.

A shaft 8 is mounted on a pair of front and rear frames 6, 6 provided on both sides of the transport conveyor 2 and supported between brackets 7, 7 attached to the upper ends of the frames. A pair of front and rear swing arms 9 are attached to each shaft 8 at their vertically intermediate portions so as to be able to swing freely within a plane perpendicular to the transport direction of the transport conveyor 2.

In this case, the swing arm 9 is fixed to a rotatable support shaft 8, but is rotatably supported by a non-rotatable support shaft 8.

The left and right swing arms 9, 9 have supporting members 10 protruding from their upper ends so as to face each other, and a guide bar 11 is attached to the tip of the supporting member 10 along the running direction of the conveyor 2. Further, support rods 13 to which one or more balance weights 12 are detachably attached are protruded from the lower ends of the swing arms 9, 9 in a facing manner.

The left and right guide bars 11 are bent such that their leading and trailing ends spread outward from each other, and between these, containers 5 to be cleaned having different widths conveyed by the conveyor 2 are received. It's getting old.

"Operation of the invention" In the above structure, the container to be cleaned 5 transported by the transport conveyor 2 enters between the left and right guide bars 11, 11 while pushing them aside depending on the width of the container. At this time, the balance weight 12 at the lower end of the swing arm 9 applies a rotational moment to the guide bar 11 so as to protrude in the opposite direction, so that the container to be cleaned 5 that has entered is pressed and supported from both sides. .

Therefore, even when containers 5 to be cleaned with different widths are continuously conveyed, the swinging arm 9 automatically follows the widths,
It is possible to stably clean the container 5 to be cleaned without being blown away sideways while holding the side surface of the container 5.

``Effects of the invention'' As described above, according to this invention, a plurality of swinging arms are installed on both sides of the running section of the conveyor, the middle portions of which are rotatably attached in a plane orthogonal to the conveyor. A series of guide bars with tips bent outward from each other are attached to the upper end of the swinging arm adjacent to the oscillating arm, and a balance weight is attached to the lower end of the swinging arm. , the containers to be cleaned transported by the transport conveyor are pushed between the left and right guide bars according to their width, and the containers to be cleaned that have entered the container are pushed in between the left and right guide bars depending on the width of the container, and the rotating moment due to the balance weight at the lower end of the swinging arm causes the containers to be cleaned to enter the container. can be supported by pressing from both sides.

Therefore, when cleaning containers with different widths, the swinging arm automatically follows the size of the width and prevents the container from being blown sideways while holding the side of the container. Cleaning can be performed stably, and unmanned and automated cleaning work can be achieved without changing the guide bar as in the conventional method.
