Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a washing machine for washing articles such as tableware.

BACKGROUND ART Conventionally, there is a type of conveyor-type washing machine for washing dishes, etc., in which a washing nozzle is arranged below a conveyor and a washing liquid is sprayed from the washing nozzle onto the dishes on the conveyor. When using this type of washing machine to continuously wash light dishes such as plastic ones, the washing liquid sprayed from below may lift the dishes off the conveyor, making it impossible to wash them thoroughly. ,
Conventionally, a conveyor in which a net for preventing floatation is provided on the upper part of the conveyor has been developed and used. A conventional example of a washing machine equipped with such a floating prevention net will be described with reference to FIG. 4 of the accompanying drawings. This conventional washing machine includes a conveyor 11 consisting of a conveyance chain or the like for conveying tableware 1 to be washed from an input port to an outlet, and a cleaning liquid tank 12 is arranged below the conveyor 11. Furthermore,
An upper cleaning nozzle 13 is provided above the conveyor 11, and a lower cleaning nozzle 1 is provided below the conveyor 11.
4 are provided, and the cleaning liquid is sent from the cleaning liquid tank 12 to the upper cleaning nozzle 13 and the lower cleaning nozzle 14 by the pump 15.
The cleaning liquid is sprayed from 14 to the conveyor 11, and the tableware 1 being conveyed by the conveyor 11
is cleaned by sprayed cleaning liquid. In this washing machine, the tableware 1 is suspended from below the conveyor 11 so as to extend along the moving direction of the conveyor 11, and the tableware 1 is suspended from the bottom of the conveyor 11 so as to prevent the tableware 1 from floating up from the conveyor 11.
A floating prevention net 16 is provided which has the effect of pressing down with its own weight. Further, in this conventional washing machine, a finishing nozzle 17 is arranged downstream of the upper washing nozzle 13 and the lower washing nozzle 14 for spraying finishing washing liquid onto the dishes on the conveyor. Therefore, in such a conventional washing machine, as long as the dishes 1 on the conveyor 11 are held down from above by the weight of the floating prevention net 16, they are not affected by the washing liquid sprayed from the lower washing nozzle 14. Therefore, the dishes are not lifted up from the conveyor 11, and the dishes are properly washed while being conveyed to the outlet.

Problems to be Solved by the Invention However, the configuration of the conventional washing machine described above has the following problems. That is, as schematically illustrated in FIG. 5A of the accompanying drawings, the tableware 1 is placed on the conveyor 11 and conveyed in the direction of arrow P, and as schematically illustrated in FIG. tableware 1
When the tableware 1A reaches the entry hole under the floating prevention net 16, the tableware 1A passes through the floating prevention net 1.
Since the tableware 1A is pressed down from above by its own weight, there is no problem such as the tableware 1A being lifted off the conveyor 11 by the cleaning liquid sprayed from the lower cleaning nozzle 14. However, Fig. 5C
As schematically illustrated in , as the conveyor 11 continues to convey the tableware, the shape of the net 16 near the entrance is deformed for the tableware 1A in the leading row, and the upper part of the tableware 1B in the following row is sufficiently pressed down. I end up not being able to wear it anymore. Then, the tableware 1B is removed from the lower washing nozzle 1.
4 may float up from the conveyor 11, making it impossible to perform subsequent cleaning effectively.

An object of the present invention is to provide a washing machine that can solve the problems of the conventional methods as described above.

Means and Effects for Solving Problems According to the present invention, there is provided a conveyor for conveying articles such as tableware to be washed, a cleaning nozzle for spraying a cleaning liquid onto the articles from below the conveyor, and a cleaning nozzle for spraying a cleaning liquid onto the articles from below the conveyor. and a floating prevention net suspended from above the conveyor so as to extend along a moving direction and for holding down the articles so that the articles do not float up from the conveyor. A presser weight is removably attached to the anti-floating net near the entrance for the article, and therefore, the article entrance portion of the anti-floating net is forced by the presser weight. Since it is made to hang down downward, it always reliably holds down the articles that come in one after another.

Embodiments Next, the present invention will be described in more detail with regard to embodiments of the present invention based on FIGS. 1, 2, and 3 of the accompanying drawings.

FIG. 1 schematically shows, in a perspective view, only the article entrance portion of an embodiment of the washing machine according to the present invention. The overall structure of the washing machine of this embodiment is substantially the same as that of the conventional washing machine described above with reference to FIG. 4, except that the presser weight is attached to the floating prevention net according to the present invention. It can be the same. As shown in FIG. 1, according to the present invention, a presser weight 20 is attached near the entrance of the tableware 1 to a floating prevention net 16A suspended above a conveyor 11A consisting of a conveyor chain.

As shown in a perspective view in FIG. 2, this presser weight 20 includes a weight rod 21 and hanging hooks 2 attached near both ends of this weight rod 21.
It consists of 2. For example, weight bar 21
is a stainless steel rod (600 mm) with a diameter of 12 mmφ and a length of 440 mm.
~800g), and stainless steel plate hooks 22 are welded near both ends of the stainless steel rod. As shown in FIG. 1, the hanging hook 22 of the presser weight 20 can be hooked to the link part of the floating prevention net 16A, and the weight rod 21 can be lifted below the net 16A. good. In this embodiment, the presser weight 20 is
Although it is said that the net 16A can be detached from and attached to the net 16A, making it detachable and attachable in this way not only makes maintenance such as cleaning of the net 16A and the presser weight 20 themselves easier, but also makes it easier to maintain the net 16A and presser weight 20 themselves, such as cleaning. Another advantage is that the presser weight 20 can be reattached to an optimal position depending on the size, shape, etc. of the presser weight 20. Also,
It is effective to freely attach the hanging hook of the presser weight to the ring portion of the net, as will be explained below.

Effects of the Invention According to the configuration of the washing machine of the present invention as described above, the following effects can be obtained. That is,
As shown schematically in FIG. 3, the tableware 1A in the most advanced row placed on the conveyor 11A and being transferred is moved under the floating prevention net 16A and further transferred to the presser weight 20. If you exceed the
The weight of the presser weight 20 reliably lowers the floating prevention net 16A downward, so that the tableware 1B that enters next is also pressed downward by the net 16A. Become. In this way, the dishes that enter one after another are always firmly held down by the net 16A, so they are not lifted upward by the cleaning liquid sprayed from the lower cleaning nozzle, and the dishes are always effectively Cleaning will be done.

Further, according to the present invention, only one presser weight is required to be attached to the floating prevention net near the entrance of the article, so the structure is simple and can be implemented at a very low cost. Furthermore, since the presser weight is removable, it not only makes maintenance such as cleaning the anti-floating net and the presser weight itself easier, but it also makes it easier to maintain the anti-floating net and the presser weight itself. Accordingly, it is possible to change the presser weight to the optimum position or to the optimum weight, and it is possible to always perform good cleaning regardless of the size of the tableware.
