Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to an inclining device for an object to be conveyed for jet cleaning, air blowing, and the like, and more particularly to a cleaning chamber for spraying a cleaning liquid and air blowing. The present invention relates to an inclining device for an article to be conveyed, which inclines a product conveyed in an air blow chamber to increase the effect of the product.

INDUSTRIAL APPLICABILITY The present invention is particularly useful for a cleaning device in which a cleaning chamber and an air blow chamber are arranged side by side.

(Prior Art) A conventional cleaning device is, for example, Japanese Utility Model Laid-Open No. 58-156579.
As disclosed in Japanese Utility Model Publication No. 58-156580 and Japanese Utility Model Publication No. 61-102282, products such as automobile parts are sequentially conveyed to a cleaning chamber and then to an adjacent air blow chamber by a conveyor device. In this case, the cleaning liquid is jetted from the nozzle toward the object to be cleaned, and in the air blow chamber, air or steam is sprayed from the nozzle toward the cleaned object to wash off the surface of the object to be cleaned. It was a mechanism.

Further, the cleaning device is further equipped with a mechanism in which ducts and pipes for supplying air and cleaning liquid to the nozzles are attached so as to be able to move up and down, and when the product is conveyed to a predetermined position, it descends and then rises after completion of the lifting. Yes, it is often used.

Further, the nozzle is arranged so that the cleaning liquid can be sprayed or air blown from as many directions as possible around the product. Particularly, in the recent cleaning devices, the nozzle is attached to the lower side of the product, often obliquely downward, and the nozzle is sprayed from below. Some have been developed that enable cleaning and air blowing. In this case, as a pallet for transporting products, a frame body assembled like a lattice, a perforated pallet, or the like is used.

(Problems to be solved by the invention) Therefore, in this type of cleaning device, as a method of further enhancing the cleaning effect and the air blowing effect, for example, the posture of the product is not changed as it is, but it is preferable to change the posture of the product. It is conceivable to inject the product so as to face the nozzle side below the product for jet cleaning and air blowing.
In particular, the air blow in the inclined posture can blow off the cleaning liquid accumulated in the inside of the product or in the recess, and is particularly effective for improving the moisture removing effect.

However, if the tilting device for the product transporting pallet including, for example, the pallet gripping means and the tilting cylinder is installed in the air blow chamber of the cleaning device, the following problems occur.

In order to ensure accurate air blow and cleaning liquid injection, it is always necessary to provide a positioning device for accurately stopping the conveyed pallet at a predetermined position and a device for canceling the stop in the pallet conveying path.

Therefore, the provision of both the pallet positioning device and the tilting device makes the entire device more complicated, and it may be impossible or practically inconvenient to combine both devices due to design restrictions.

Moreover, even if the pallet is equipped with a tilting device and the pallet can be maintained in a tilted position, the members of the pallet positioning device interfere, and the blow air from the nozzle or the jet cleaning liquid does not reach the product well, which is the expected effect. May not be sufficiently improved.

Further, the process of tilting the pallet following positioning of the pallet is performed. If the pallet is tilted after positioning once, it is inevitable that the pallet deviates from a predetermined position and a so-called misalignment occurs. Is also needed.

The present invention has been made in consideration of the above circumstances, and an object thereof is to solve the above-mentioned problems and to maintain an inclined posture such that air blow and jet cleaning are not disturbed by other members, It is possible to perform it sufficiently effectively, and also it is possible to position the transfer pallet itself, and the whole device is very simple. The inclination of the transferred product for jet cleaning, air blow, etc. It is an object of the present invention to provide an apparatus, and a technical problem thereof is to combine a tilting function of a pallet and a positioning function thereof with a single member configuration.

(Means for Solving the Problems) The present invention relates to a jig for receiving a transfer pallet, which has a role of a stopper for the pallet in addition to one inclined posture for improving the effect of air blow and the like. It is intended to fulfill.

That is, the device for inclining a conveyed product for jet cleaning, air blow, etc. according to the present invention is a device for stopping and inclining a product on a conveyed pallet for jet cleaning, air blow, etc. in a cleaning chamber, an air blow chamber, etc. A pallet receiving jig located slightly below the pallet conveying surface and having a stopper portion on the pallet advancing side, and a support for rotatably supporting the pallet receiving jig at a position on the pallet arrival side with respect to its center of gravity. Means and cam means for contacting the lower surface of the pallet advancing side portion of the pallet receiving jig and inclining the pallet receiving jig by rotation so that the stopper portion can project above the pallet conveying surface. And a lifting mechanism that allows the pallet receiving side part to be tilted higher than the pallet advancing side part. It is characterized by that.

The pallet receiving jig is located, for example, slightly below the upper surface of the pallet transport conveyor, and has a stopper portion on the pallet advancing side, usually at the end thereof. Another stopper may be provided on the pallet advancing side at a position where the pallet is well engaged. The receiving jig is a single member that supports the entire pallet, or a plurality of members that are arranged in the pallet width direction and integrally joined by a connecting material so that the entire pallet can be supported. May be. But,
In the latter case, the pallet receiving jig needs to have a lattice-shaped frame structure like the pallet in order to ensure air blow and liquid injection from the lower side of the product.

The support means of the pallet receiving jig rotatably supports the receiving jig at a position on the pallet arrival side with respect to its center of gravity, and is composed of, for example, a support shaft and a bearing. Therefore, the receiving jig has a configuration in which the gravitational force always tries to rotate in a direction in which the pallet arrival side is high and the pallet advancing side is low and inclined.

The cam means is composed of, for example, a specially shaped stopper cam that comes into contact with the lower surface of the pallet advancing side portion of the pallet receiving jig, and a rotating device (such as a coupling shaft) that rotates the stopper cam. With respect to the outer shape of the stopper cam, the rotation of the cam causes the contacting pallet advancing side portion to be raised, and the pallet receiving jig is tilted so that the pallet advancing side is higher than the arrival side.
It is sufficient that the stopper portion on the advancing side can be projected above the pallet conveying surface.

The lift mechanism is composed of, for example, a cylinder device capable of moving up and down the supporting means. As the support means moves up and down, the pallet receiving jig simultaneously rotates as described above, and the pallet arrival side is inclined higher than the pallet advancing side.
Therefore, in order to stop this rotation and keep the desired inclined posture constant, it is preferable to provide a receiving jig stopper below the pallet receiving jig on the advancing side so as to move up and down together with the receiving jig. .

(Operation) In the device of the present invention, the pallet receiving jig is made to stand by slightly below the pallet conveying surface, and when the pallet is conveyed, the pallet receiving jig is inclined by the action of the cam means, and the stopper portion Can be projected above the transport surface to lock the pallet. That is, the pallet can be stopped at a predetermined position.

Subsequently, when the supporting means of the receiving jig is lifted by the operation of the lift mechanism, the pallet receiving jig is simultaneously rotated by its gravity action, and the pallet arrival side is greatly inclined to a posture higher than the traveling side. Therefore, by arranging an air blow nozzle or the like in advance obliquely below the pallet conveying surface on the advancing side, the lower surface of the product on the pallet inclined in the above posture can be directed to the nozzle, and the air blow or the like can be effectively performed. Can be done

Moreover, even if the pallet receiving jig is rotated when the support means is raised, the pallet is not unlocked by the stopper portion, so that the position of the pallet initially positioned can be maintained as it is. Can be performed exactly as prescribed. This action and function are similarly exerted even when the supporting means is lowered. Therefore, the positioned position can be stably maintained without being affected by the tilting operation of the pallet.

Further, when the cam means is reversely rotated after the lowering of the support means, the pallet receiving jig is rotated by the action of gravity, and the locking of the pallet by the stopper portion is released. That is, the operation of releasing the lock of the pallet is also performed simultaneously with the operation of returning the pallet from the inclined attitude to the horizontal attitude for transport again. Thus, the device of the present invention, including the ending operation, operates smoothly and easily.
