Description

DETAILED DESCRIPTION OF THE INVENTION A. Purpose of the Invention (Field of Industrial Application) The present invention relates to a conveyor that sequentially transfers articles to a first and second conveyor.

(Conventional technology) Conventionally, several stages of conveyors were installed inside the processing chamber.
A conveyor that sequentially transfers items from the upper level to the next level is, for example,
This is known from Japanese Utility Model Publication No. 3591 and Japanese Utility Model Publication No. 56-9189, etc., and in the former, several independent stages of conveyors are arranged alternately with their positions shifted to the left and right, and the articles on the upper conveyor are transferred from the end of the conveyor to the next conveyor. The latter is a system in which a series of chain conveyors are suspended in a meandering manner, with a part of the chain conveyor inside the processing chamber extending outside the processing chamber, and the transfer plate is pivoted to this chain conveyor. and hold the transfer plate horizontally while engaging the guide to convey the article;
When it comes off the guide, it hangs down, causing the articles on the upper conveyor to fall onto the next conveyor, thereby transferring the articles.

(Problems to be solved by the invention) Among the conventional conveyors mentioned above, an inexpensive conveyor with a general structure is sufficient, but if it becomes contaminated, it must be cleaned within the processing room. However, there are problems in that it is very troublesome and it is not possible to check the cleaning results, making cleaning work difficult.
Since this part can be cleaned, the cleaning results can be confirmed, and the droplets do not adhere to other parts of the conveyor or the processing chamber, so complete cleaning without leaving any dirt is possible. There was a problem in that a complicated structure had to be adopted in which a large number of transfer plates were rotatably attached to the chain, and a guide with a portion of the terminal end side was engaged with the transfer plates.

The present invention was made in order to solve the problems of the conventional conveyors described above, and the first and second meandering conveyors are arranged alternately to enable transfer and transfer of articles using a conveyor with a simple structure. This relates to conveyors that

B. Structure of the invention (means for solving problems) In order to achieve the above object, the transfer conveyor of the present invention enters the processing chamber from above on one side and exits from below while meandering inside the processing chamber. a first conveyor that returns to its original position, and a second conveyor that enters the processing chamber from above the other, meanderes between the stages of the first conveyor, exits from below, and returns to its original position. In addition, parts of the first and second conveyors are located outside the processing chamber, and cleaning means is provided near the positions.

(Function) The transfer transfer conveyor configured as described above rotates the first and second conveyors 5 and 7 in opposite directions at the same speed while transferring the first and second conveyors at the entrance 2 of the processing chamber 1. When the article is supplied to the starting end of the conveyor 5, the article is carried to the left side as shown in the drawing by the first stage transfer section a of the first conveyor 5, and when it reaches the end, it is transferred to the first stage of the second conveyor 7. The first conveyor 5 falls into the second stage transfer section b of the first conveyor 5, is carried to the left by this section, and is carried from the last end to the second stage. It falls to the second-stage transfer section f of the conveyor 7 and is carried to the right side. Repeating the same operation as above, it is sequentially transferred and transferred from transfer section f to c, from c to g, from g to d, and from d to h. From, processing chamber 1
By supplying steam, hot air, cold water, etc. into the container and bringing it into contact with the articles to be transferred, the articles can be automatically and uniformly subjected to treatments such as heating, sterilization, and cooling.

Further, if the above-mentioned processing is continued, the first and second conveyors 5 and 7 become dirty due to adhesion of residues and the like from the articles.
In this case, a cleaning means disposed near the first and second conveyors 5 and 7 located outside the processing chamber 1, for example,
If the conveyors 5 and 7 are cleaned using the cleaning nozzles 9 and 12, the cleaning results can be checked.
During cleaning, droplets may fall onto other parts of the conveyor or processing room 1.
It will not adhere to the surface and stain them.

(Example) Next, an example of the implementation of the transfer conveyor according to the present invention will be described based on the drawings.

In the figure, reference numeral 1 denotes a processing chamber, which has an article inlet 2 in the upper part of one side, a conveyor port 3 in the upper part of the other side, and an article outlet 4 in the lower part.

5 is a first conveyor, which enters the processing chamber 1 from the article entrance 2 and snakes inside from top to bottom to convey 4.
The stage transfer parts a, b, c, and d are formed, and after exiting from the exit 4 to the outside of the processing chamber 1, it passes under the processing chamber 1 and is suspended in the direction shown by the arrow in the drawing. A motor 6 is used to rotate the motor 6.

7 is a second conveyor that enters the processing chamber 1 from the conveyor port 3, snakes between the first conveyors 5 from top to bottom, and passes through four stages of transfer sections e, f, g, and h. After forming e, f, g, and h, pull it back to its original position and move the motor 8 in the direction shown by the arrow in the drawing.
It is designed to rotate.

Reference numeral 9 denotes a cleaning means (for example, a cleaning nozzle) installed opposite to the part of the first conveyor 5 that exits the processing chamber 1, and the water in the water tank 10 is pumped by a pump 11 and sprayed onto the first conveyor 5, so that the water adheres to the first conveyor 5. This removes any dirt that may be present.

Reference numeral 12 denotes a cleaning means (for example, a cleaning nozzle) installed opposite to the part of the second conveyor 7 that exits from the processing chamber 1.
Then, the water in the water tank 13 is pumped by the pump 14 and sprayed onto the second conveyor 7 to remove adhering dirt.

In the conveyor shown in the above embodiment, the meandering first conveyor 5 and second conveyor 7 are arranged in a staggered manner, which not only ensures the transfer and transfer of articles, but also ensures that the parts extending outside the processing chamber are It was possible to completely clean the product without staining it.

C. Effects of the Invention Since the present invention is configured as described above, it produces the effects described below.

The transfer conveyor of the present invention is configured such that the second conveyor meanderes between each stage of the first conveyor and comes out from below and returns to its original position, so that articles can be transferred using an ordinary belt conveyor. Since it can be transported, the structure can be simplified and equipment can be saved.

Moreover, by taking a part of the first and second conveyors outside the processing chamber and cleaning them there, the cleaning results can be confirmed and the cleaning work can be easily performed.

It has the following unique effects.
