Take out and supply to the supply conveyor. As a result, in the process in which the cultivation container supplied on the turntable moves along the circumference, first the lid is opened by the lid opening device, then the seed container is filled in the cultivation container by the seed germ filling device, and then the lid is closed. After the device covers the cultivation container with the lid and seals the container, the container is unloaded by the unloading conveyor. An operator stores the cultivated containers thus carried out one by one in a container, and stores a predetermined number of containers in the cultivating shelf.

Further, as a device of this type, a container containing a cultivation container is supplied to a position corresponding to inoculation of seeds by a supply conveyor, and the cultivation container is filled with the seeds in a state of being housed in the container. It is proposed in Japanese Patent No. 174311. This supplies the container to the seed inoculation corresponding position by the supply conveyor, and sequentially opens the lid, fills the seed, and closes the lid for the plurality of cultivation containers in the container.
After that, the container is carried out by a carry-out conveyor, and the work of putting the cultivation containers in and out one by one can be omitted.

In the above prior art, the scraping rod having a scraping blade at the upper end is linearly raised while being rotated in accordance with the substantially central position of the seed germ container, or the seed germ is moved against the scraping blade. Since the mounting cylinder that holds the container is lowered, the scraping blade inserted from the small diameter neck of the seed container has a problem that the seed bacteria around the large body remains uneconomical in the container. In consideration of this point, for example, one in which a spring is interposed between the scraping rod and the scraping blade to scrape out the inoculum on the inner peripheral wall of the body of the large container is considered.

However, the seed container generally has a small diameter at the neck portion of the container which covers the body of the container, and when the seed bacteria filled up to the neck portion of the seed container are scraped out, In the conventional structure, the amount of movement due to the raising of the raking rod or the lowering of the mounting cylinder that holds the seed germ container is kept constant. There is a problem that the amount of seed germs scratched out differs depending on whether or not the filled seed germs are scratched, and the amount of seed germs scratched out tends to be small particularly at the neck or shoulder of the container having a small volume capacity.

Therefore, the present invention provides an inoculum scraping device in a mushroom inoculum inoculating device, which can keep the amount of inoculum filled in the inoculum container having different diameters of the body portion and the neck portion substantially constant at a predetermined amount. The purpose is to do.

[0008]

According to the set program, a drive signal is output to the drive circuit 118 of the motor 74, which is a scraping lifting drive member, to drive the motor 74, and the scraping is performed according to the scraping time based on the area A. The motor 88, which is a rotary drive member, and the motor 69, which is a cylinder rotary drive member, are rotationally driven based on the drive signal of the drive circuit 118, whereby a predetermined amount of inoculum b preset is scraped out, and the inside of the cultivation container 8 A predetermined amount of inoculum b is supplied to.

Therefore, after the operation of the container width detecting sensor S, the state of the area A in which the roller 86 is in pressure contact with the linear cam surface 85A of the cam plate 84 corresponding to the body portion 66A of the inoculum container 66 is maintained, The inoculum b can be scraped out to the deepest part of the container 66 with a predetermined scraping time set.

The present invention is not limited to the above-mentioned embodiments, and various modifications can be made within the scope of the present invention. For example, as shown in FIG.
The cam surface 85 of the cam plate 84 formed to substantially follow the shape of 66.
The straight cam surface 85A and the neck that fit the body 66A of the seed container 66.
Container width detection sensors S1 and S2 for detecting the outer dimensions of the inoculum container 66 are provided, which are formed by a straight cam surface 85B that fits 66B and an inclined cam surface 85D that extends substantially along the shoulder 66C. The detection sensors S1 and S2 detect the width of one container at the boundary between the straight cam surface 85B and the inclined cam surface 85D, which is a position aligned with the boundary between the neck 66B and the shoulder 66C of the inoculum container 66 provided on the cam plate 84. While installing the sensor S1,
The other container width detection sensor S2 is installed at the boundary between the inclined cam surface 85D and the straight cam surface 85A, which is a position aligned with the boundary between the shoulder portion 66C and the body portion 66A, and signals from the sensors S1 and S2 are provided. Based on the program preset based on the above, the inoculum b is scraped out according to the three steps of the region corresponding to the neck 66B position of the inoculum container 66, the region corresponding to the shoulder 66C position, and the region corresponding to the body 66A position. You may make it respectively set time.

Further, the scraping time is sequentially set shorter based on the signal from the container width detecting sensor, and when the position corresponding to the position of the body 66A is reached, the inoculum b is scraped at a preset constant scraping time. Good.
