Abstract

PURPOSE:To reduce the number of working steps and facilitate a controlling operation by a method wherein each of sample boxes is provided with a bottom plate having an aerating characteristic for use in dividing an interior of each of the sample boxes into an upper half and a lower half. CONSTITUTION:As a self-inspecting sample is stored in a sample receiving hopper 17, it is stored in an upper half 31 of a sample box 30 and then the sample box 30 is transported into a target drying chamber 2. Upon completion of drying operation, the sample box 30 is transported from a drying chamber 2 to a sample discharging position, where the sample box 30 is reversed upside down and then a dried sample stored at the upper half part 31 of the sample box 30 is dropped into a sample discharging hopper 18. The sample box 30 which is made vacant in this way is set such that in this case its lower half part 32 comes to an upper side and a next self-inspecting sample can be stored at the lower half part 32, resulting in that the sample box is transported into the drying chamber 2 as it is so as to wait for a loading of next sample. Accordingly, only one time reversing of the sample box is sufficient at a drying and discharging step of the self-inspecting sample and so the number of steps can be reduced.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is applied to a grain drying and preparation facility that receives grain from each producer, goes through the steps of drying, sorting, and storage, and then ships it. , the receipt relates to the improvement of a sample dryer that dries samples for voluntary testing from a portion of grain.

(Prior technology) Conventionally, when receiving consignments from each producer, a portion of the grain is collected in a sample box as a sample for self-inspection, and then a worker transports the sample box one by one to a sample dryer, and then the sample box is placed in the drying room. was used to dry samples for self-testing.

Therefore, conventionally, it is necessary to store the sample box containing samples for self-inspection in the drying chamber of the sample dryer and to remove it from the drying chamber.

Therefore, it was desired to automate this process to save labor, and the present inventor prototyped a sample dryer as shown in FIGS. 1 and 2.

In the figure, 1 is a sample dryer equipped with a large number of drying chambers 2 for drying samples for self-assay, and 3 is a sample box accommodated in the drying chambers 2. This sample box 3 is provided with a ventilation hole at its bottom.

4, the sample box 3 containing the sample is placed in the target drying chamber 2.
At the same time, after drying, the sample box 3
This is a sample loading/unloading device for loading and unloading samples, and consists of each component as described in vk.

5A and 5B are a pair of upper and lower running rails, which are arranged parallel to each other in the X direction (left and right direction) above and below the front of the sample dryer 1. Sliding members 6A and 6B are slidably mounted on the traveling rails 5A and 5B, respectively, and a rack 7 is mounted on the sliding members 6A and 6B.

An X-direction transport motor 8 is fixed to the sliding member 6B, and a gear 9 is attached to the shaft of the motor 8 so that the gear 9 meshes with a rack 10 provided along the side surface of the running rail 5B. With such a configuration, the X direction transport motor 8
The rack 7 can be moved in the X direction by forward and reverse rotation.

Reference numeral 11 denotes a conveyance table having a through hole penetrating through the rack 7, passing through the through hole into the rack 7, and mounting a motor 12 for conveyance in the Y direction. A gear 13 is attached to the shaft of this motor 12 so that this gear 13 meshes with the rack 7. With such a configuration, the Y-direction conveyance motor 1
The conveyance table 11 can be moved in the Y direction by the forward and reverse rotations of 2.

14 is mounted on the conveyor table 11, and the shaft 1 is mounted in two directions (back and forth directions).
4A is a movable near motor, and a rotary actuator 15 that rotates 180 degrees is fixed to the tip of this shaft 14A, and an electromagnet 16 that attracts the sample box 3 is further fixed to the tip of the rotary actuator 15. Therefore, the electromagnet 16 can rotate 180''.

The shaft 14A of the linear motor 14 is equipped with a limit switch LSI that detects when the shaft 14A moves forward and picks up the sample box 3, and a limit switch that detects when the shaft 14A moves backward and returns to its original position. Install each LS2.

Reference numeral 17 denotes a sample receiving hopper in which a sample for self-inspection before being dried in the drying chamber 2 of sample drying@i is temporarily received and accommodated.

Reference numeral 18 denotes a sample discharge hopper for discharging the sample for self-inspection after drying in the drying chamber 2.

Now, when the sample for self-inspection collected by the sample collecting device is stored in the sample receiving hopper 17, the transport table 11 waiting at a fixed position is moved by the X-direction transport motor to the target loading position of the drying chamber 2. 8 and the Y-direction transport motor 12 . Here, since the target drying chamber 2 is specified in advance by the coordinates, the amount of movement of the conveyor table 11 in the X direction and the Y direction can also be determined, so the motors 8 and 12 are rotated according to the amount of movement. do.

Then, when the conveyance table 11 stops at the target loading position of the drying chamber 2, the linear motor 14 is driven and its shaft 14 is driven.
A starts moving forward and stops when the limit switch LSI is activated. Here, the electromagnet 1 provided at the tip of the shaft 14A
6 and the empty sample box 3 come into contact with each other, and when the electromagnet 16 is energized, the sample box 3 is attracted to the electromagnet 16.

In this state, the linear motor 14 is driven and its shaft 14A starts to move backward, and when the limit switch LS2 is actuated, it stops in the state shown in FIG. 2.

Next, the empty sample box 3 is transported toward the sample receiving hopper 17 by the movement of the transport table 11, and is stopped at a position directly below the hopper 17. Here, the discharge valve of the hopper 17 is opened, and the sample for self-testing is put into the drying box 3.

When the input is completed, the sample box 3 is again transported to the target drying chamber 2 by the conveyor table 11, where the shaft 14A of the linear motor 14 advances and the sample box 3 is accommodated in the drying chamber 2. , the electromagnet 16 is de-energized and the shaft 14
A retreats. Thereafter, the conveyance table 11 moves to a normal position and enters a standby state.

Through this series of operations, the sample receiver is placed in hopper 1.
The samples for self-testing stored in box 7 are stored in sample box 3.
After being put into the target drying chamber 2, each sample is sequentially stored in the target drying chamber 2 and dried.

When the drying of the sample for self-inspection is completed, the transport table 11 starts moving toward its target loading position in the drying chamber 2, and stops at that position. Here, the linear motor 14 is driven and the electromagnet 16 is energized to attract the sample box 3 containing the dried sample and pull it out from the drying chamber 2.

Next, this sample box 3 is transported toward the sample discharge hopper 18 by moving the transport table 11, and the hopper 1
Stop at a position facing the entrance of No. 8. Here, when the rotary actuator 15 rotates 180 degrees, the sample box 3 integrated therewith rotates 180 degrees, so that the dried sample is thrown into the sample discharge hopper 18. The sample placed in this hopper 18 is subjected to self-inspection in the primary process.

When the sample input is completed, the rotary actuator 15 further rotates by 180°, and the -band sample box 3 also rotates by 180°, and the sample box 3 returns to its original state. In this state, the sample box 3 is transported by the transport table 11 to the original drying chamber 2, and is housed in the drying chamber 2 here.

(Problem to be Solved by the Invention) Therefore, in the dryer as described above, after drying is completed, the sample box 3 is turned upside down and the sample inside is discharged, and after the sample is discharged, the sample box 3 is re-opened. The process has to be reversed to return to its original state and returned to the drying chamber, resulting in the problem of increasing the number of work steps and complicating control procedures.

Therefore, in view of the above points, it is an object of the present invention to reduce the number of work steps and thereby simplify control.

(Problems to be Solved by the Invention) In order to achieve the above object, the present invention employs the following configuration.

That is, the present invention partitions a main body of a dryer equipped with a hot air generation source into a number of compartments, and automatically inserts a number of sample boxes containing grain samples into predetermined compartments one after another by a robot arm. Dry the sample with hot air,
After drying, the sample box is removed from the compartment, turned upside down, and the samples in one box are discharged outside the machine. It is attached to a sample box.

(Function) Next, the function of the present invention will be explained with reference to embodiments of the drawings.

Now, when the samples for self-testing are stored in the sample receiving hopper 17, the samples are stored in the upper half 31 of the sample box 30, and then the sample box 30 is carried into the target drying chamber 2. .

When drying is completed, the sample box 30 is carried out from the drying chamber 2 to the sample discharge position, where the sample box 30 is turned upside down, so that the upper half 31 of the sample box 30
The dried sample accommodated in the hopper 18 falls into the sample discharge hopper 18.

The sample box 30 is emptied in this way.

This time, the lower half 32 is on the upper side, and the next self-testing sample can be accommodated in this lower half 32, so it is carried into the drying room z as it is.

Waiting for the next sample to be collected.

Therefore, the sample box 30 only needs to be turned upside down once in the process of drying and discharging the self-testing samples, thereby reducing the number of processes.

(Embodiment) In an embodiment of the present invention, a sample box 30 is configured as shown in FIGS. 3 and 4, and the other configurations are the same as the dryer shown in FIGS. 1 and 2. Therefore, its explanation will be omitted.

The sample box 30 has an air-permeable bottom plate 33 attached therein, which divides the sample box into an upper half 31 and a lower half 32. The ventilation of the bottom plate 33 is achieved by punching a large number of ventilation holes 33A.

In the embodiment configured as described above, when a sample for self-testing is stored in the sample receiving hopper 17, the sample is stored in the upper half 31 of the sample box 30, and then the sample box 30 is used for carrying in the sample. It is carried into the target drying chamber 2 by the extraction device 4.

When the drying of the sample is completed, the sample box 30 is carried out from the drying chamber 2 to the sample discharge position by the sample carry-in/out device 4, and here the sample box 30 is turned upside down by the drive of the row actuator 15. As a result, the dried sample contained in the upper half 31 of the sample box 30 falls into the hopper 18.

The lower half 32 of the sample box 30 emptied in this way is now on the upper side, and the next self-testing sample can be accommodated in this lower half 32. Therefore, sample box 3
0 is carried as it is into the original drying chamber 2 by the sample carrying/unloading device 4, and waits to receive the sample for the first self-inspection.

In this way, in the sample box 30 of the embodiment of the present invention, samples are alternately stored in the upper half 31 and the lower half 32 for drying.

Therefore, for example, if the sample a for self-inspection becomes clogged in the ventilation hole 33A of the bottom plate 33 as shown in FIG. 5(A), when the sample box 30 is reversed, as shown in FIG. Since the sample a falls due to its own weight or the pressing force of the next sample, the bottom plate 33 will not be clogged.

(Effects of the Invention) As described above, in the present invention, the sample box is divided into an upper half and a lower half by a breathable bottom plate so that these two parts can be used alternately. Since the sample box only needs to be turned upside down once, the number of work steps can be reduced, and control can be simplified.

Furthermore, in the present invention, the sample box is divided into an upper half and a lower half by a breathable bottom plate so that these two parts can be used alternately. This prevents the sample from falling due to the pressure of the sample and clogging the bottom plate.
