Description

DETAILED DESCRIPTION OF THE INVENTION a. Object of the Invention (Industrial Field of Application) An article rocking apparatus according to the present invention is incorporated in, for example, an automatic ultrasonic cleaning apparatus, and a cleaning basket immersed in a cleaning tank or a stink tank with an object to be cleaned stored therein. Can be shaken in the detergent stored in the washing tank or the rinsing tank, or in water.

(Prior Art) When cleaning an object to be cleaned such as a dirty surgical tool in a hospital or the like, the object to be cleaned is stored in a cleaning basket and the basket is used as a detergent in a cleaning tank. It is often used to apply ultrasonic vibration to the cleaning tank to remove stains on the objects to be cleaned stored in the cleaning basket.

When the cleaning object in the cleaning basket is cleaned in the cleaning tank to which ultrasonic vibration is applied, the cleaning basket is transferred to the rinsing tank to remove the detergent attached to the cleaning object in the cleaning basket.

The cleaning basket containing the object to be cleaned whose dirt has been removed in the cleaning tank and the detergent removed in the rinsing tank is then transferred to the drying tank to interfere with the wet object to be cleaned by cleaning and rinsing.

Cleaning, rinsing, and drying of the object to be cleaned by the ultrasonic cleaning device are performed as described above, but in order to efficiently perform the cleaning operation and the rinsing operation, the cleaning tank in which the cleaning basket is immersed, It is effective to apply ultrasonic vibration to the rinsing tank and shake the washing basket in detergent or water.

Therefore, conventionally, as disclosed in, for example, JP-A-53-62365 and JP-A-56-115680, a device for rocking a cleaning layer or a cleaning basket immersed in a rinse tank has been developed and used. Has been done.

(Problems to be solved by the invention) However, in the case of the swing device of the cleaning basket incorporated in the conventional ultrasonic cleaning device, a dedicated cleaning basket is used as a cleaning basket for locking the arm of the cleaning device. Had to prepare.

For this reason, there are various inconveniences such as the high cost associated with the production of a special cleaning basket and the need to move the object to be cleaned to a dedicated cleaning basket one by one when performing the cleaning work.

The article rocking device of the present invention eliminates the above-mentioned inconvenience.

b. Configuration of the Invention (Means for Solving the Problem) The article rocking device of the present invention is an upper support plate having a flat upper surface at the lower end portions of a pair of hanging arms provided in parallel with each other and spaced apart from each other. The upper support plate is swingably supported between the lower end portions of the pair of hanging arms by pivotally supporting the side plates fixed upward from the left and right side edges of the pair by the pair of left and right horizontal shafts. I support you.

Also, by supporting side plates fixed upward from both left and right edges of the lower support plate provided on the lower side of the upper support plate on a horizontal axis concentric with the side plate of the upper support plate, The plate is swingably supported on the lower portion of the upper support plate between the lower ends of the pair of suspension arms.

At least a part of the front and rear edges of the lower support plate is bent upward to form a restraining piece, and the upper end of the restraining piece is lower than the upper surface of the upper supporting plate when the upper and lower supporting plates are not rotated. Is located in.

The portion of the upper support plate that is aligned with the holding piece is a plate-less portion that allows the holding piece to move upward.

Furthermore, an end portion of a connecting arm that reciprocates the pivot is pivotally supported by a pivot provided on a portion of the side plate fixed to the top support plate, which is deviated from the horizontal axis, so that the top support plate can be swung by an external force. .

(Operation) When the article swinging device of the present invention configured as described above is used to swing an article such as a cleaning basket, the article to be swung is placed on the upper surface of the upper support plate and is moved by the connecting arm. The pivot provided on the side plate of the upper support plate is reciprocated.

With the reciprocating movement of the pivot, the upper support plate swings about the horizontal axis. During this swinging, while the inclination angle of the upper support plate is small, the article is held on the upper surface of the upper support plate based on the friction between the upper surface of the upper support plate and the lower surface of the article.

When the inclination angle of the upper support plate becomes large and the article cannot be held by the frictional force between the upper surface of the upper support plate and the lower surface of the article, the article tries to slide down from the upper surface of the upper support plate. When the upper support plate is greatly inclined like this, the restraining piece at the end of the lower support plate that swings independently of the upper support plate is located above the upper support plate from the plate-less portion of the upper support plate. Because it protrudes, the bottom edge of the article collides with this restraining piece,
This restraining piece prevents the article from falling from the upper surface of the upper support plate.

When both upper and lower support plates are not swinging, the upper end of the restraining piece at the end of the lower support plate is located below the upper surface of the upper support plate, so the upper surface of the upper support plate is flat. Thus, the work of taking the article in and out of the upper support plate can be easily performed while dragging the article.
