DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Figure 1 is an outline of the flower bulb dry sorting facility.
The facility is an automated process for commercializing the flower bulbs shipped from the producer, and includes a receiving section A, a cleaning section B, a primary drying section C,
It comprises a pretreatment section D, a sorting and sorting section E, a main drying section F, a shipping and sorting section G, and auxiliary equipment.

The cargo receiving section A is composed of a ventilation duct 3 having a placing section 2 for accumulating the containers 1 containing the bulbs, and is placed on the placing section 2 from the truck 4 via a lifting device as appropriate. The containers 1 are sequentially stacked and provided so that the container 1 can be ventilated arbitrarily during the mounting period. The washing unit B dips and transfers all the flower bulbs supplied while inverting the bulb storage container 1 sequentially transferred from the cargo receiving unit A via the container transport conveyor 5 by the container damper 6 and immersing it in the water tank 7. It is a structure that can remove adhered mud. Reference numeral 8 is a transfer conveyor.

Reference numeral 9 is a draining conveyor which receives the cleaning material from the cleaning section B from the transfer conveyor 8 and supplies and transfers it to the primary drying section C. The draining conveyor 9 is a conveyor belt 10
The transport lugs 11 are attached to the upper part at predetermined intervals, and the washed bulbs are received by the transport lugs 11 and transported. The conveyor belt 10 is provided with small ball leakage holes 12 to the extent that unnecessary small ball products that do not become products as seed bulbs leak. The leakage hole 12 also serves as a drainage hole for blowing off water droplets adhering to the surface of the bulb with a water draining fan 13 to remove and drop the water droplets. Reference numeral 14 is a guide shoe which receives the unwanted bulbs leaking through the leak holes 12 and guides them downward, and to a discharge belt conveyor (which may be a roller conveyor) 15 for taking out the unwanted bulbs to the outside. I am in touch. In this embodiment, the unnecessary bulb guide shoe 14 also serves as a drain gutter for draining water drops after draining.

The primary drying section C is carried out in order to smoothly perform the root removing action in the subsequent process, and is designed to dry the initial moisture content of the bulb of about 80% to about 50%. That is, the primary drying unit C includes an upper buffering tank 16, a mesh conveyor 17 having a zigzag-shaped inclined guide surface in the drying chamber, a dehumidifier 18, and the like, and is slowly moved by dehumidifying air appropriately supplied to the device. It is a structure that can be dried.

The bulbs discharged from the primary drying section C are
The relay tank 19 also used for tempering is transferred and stored. Next, the pretreatment unit D is a stock separator 20,
A coarse sorter 21, a root remover 22, a wax machine 23, and a wax dryer 24 are arranged in this order to perform pretreatment for sorting, main drying, and storage.

The sorting / sorting section E has a sorting machine 25 and drawer conveyors 26, 26 provided corresponding to the sorting classes. The sorting machine 25 adopts a belt-conveying type sorting section having sorting holes. It is a structure in which the rank is sorted into 4 ranks of 2S, S, M, and L. In addition, when removing unnecessary small globular products by the draining conveyor 9, among the rank 4 ranks,
It is possible to reduce one rank, for example, the rank of class 2S.

Drawer conveyor 2 arranged for each class
6 is provided with a ball number counter 27, and the conveyor 2
The grade-specific bulbs discharged from the six ends can be accommodated in a fixed quantity in the container transferred by the container transfer conveyor 28. The bulb storage container is loaded in the container. The loading / unloading conveyor 29 and the palletizing robot 30 move the unmanned forklift 31 to the main drying unit F.
To be housed.

The main drying section F is for the purpose of preventing spoilage at the distribution stage due to its still high water content. In this embodiment, the main drying section F is divided into three chambers, and is arbitrarily divided according to the shipping time, the type of product, etc. Although it can be selectively housed, dehumidified air from a dehumidifier can be introduced in any case, and cooling storage can be performed subsequent to drying by controlling the cooling air.

The shipping and sorting section G includes an unmanned forklift 31.
On the contrary, a product transfer conveyor 32 or a relay conveyor 33 that receives the storage container returned to the conveyor 29 by distinguishing between small balls and shipping balls is arranged, and semi-automatic dampers 34, 34 are provided at the end portions of the respective conveyors 32, 33. 35 are provided. The bulbs discharged from the shipping ball damper 34 pass through the final inspection table conveyor 36 and are subjected to a ball number counting process by a ball number counter 37, and are molded by a box making machine 38 to form an empty box supply shunt 39.
It is housed in a corrugated ball box that descends at. Four
Reference numeral 0 is a storage portion for storing a pallet, and 41 is a sealing machine for sealing a corrugated box containing the shipping balls.

As shown in the embodiment of FIG. 3, the mesh conveyor 17 in the primary drying section C for primary drying the washed bulbs may also be used to sort out unnecessary small spheres by leakage. The mesh size of the mesh conveyer 17 is a leakage hole 17a that allows unnecessary small ball products to leak.
And The unnecessary small ball products leaking from the leak hole 17a are discharged by the belt conveyors 42 and 43 arranged in the mesh conveyor. Therefore, even with this configuration, it is possible to achieve the same effect as the sorting effect by the draining conveyor and to improve the drying efficiency.
