Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a grain weighing and bagging device that bags and weighs grains of rice, wheat, etc. in predetermined amounts.

(Prior art) When an empty grain bag is placed on a scale and grains are loaded into the bag from the hopper at the top to fill bags in predetermined amounts, the empty grain bag does not fall into the scale in a stable manner. Since grain bags are difficult to stand up and easily fall down, Japanese Utility Model Application Publication No. 59-69122 describes a technical means for holding grain bags with the bag mouth open.

In addition, in order to make it easier to unload the grain bags from the top of the scale after bagging, a technical means was developed in 16663 (1983) to scoop the grain bags after bagging from the top of the scale using a transport cart equipped with a fork. It is stated in the No.

(Problem to be solved by the invention) When scooping a grain bag with the fork-equipped transport cart and lowering it from the top of the scale, after scooping the grain bag with the fork, the bag opening holding the bag opening is removed. The holding state of the holder must be released. For this reason, the work is troublesome and the grain bag cannot be unloaded quickly.

(Technical means for solving the problems) A pedestal 16 into which the fork 5 of the transport cart 4 can be inserted onto the weighing device 3, and a pedestal 16 which can hold the bag opening of the grain bag 2 mounted on the pedestal 16. The grain holding device 1 is provided with a detection device 6 for detecting the insertion of the fork 5 into the pedestal 16, and is configured to release the bag holding action of the holder 1 when the detection device 6 detects the insertion of the fork 5 into the pedestal 16. The configuration is a grain measuring and bagging device.

(Effect of the invention) When weighing and packing grain into bags, the grain bag 2 is mounted on the pedestal 16 on the scale 3, and the bag opening of the grain bag 2 is set upright on the scale 3. The grains are held by a holder 1 provided as a container, and the grains are fed in this state. When a predetermined weight of grains is filled with this grain supply, the measuring device 3 detects this, closes the shutter 13, and stops the supply.

Next, when lowering the grain bag 2 to be filled with grains from the pedestal 16, operate the transport cart 4 and insert the fork 5 between the bottom of the grain bag 2 and the pedestal 16. The detection tool 6 detects the insertion of the fork 5, and in conjunction with this detection action, the holding action of the holder 1 that holds the bag opening of the grain bag 2 is released. Therefore, by moving the fork 5 upward, the grain bag 2 can be mounted on the fork 5, and at the same time, the transportation cart 4 can be moved to transport the grain bag 2 from the scale 3 to a predetermined location.

(Effects of the invention) Since this invention is constructed as described above, when weighing and bagging, the bottom of the grain bag 2 is mounted on the pedestal 16 and the bag opening is held on the holder 1 for stability. However, when the grain bag 2 after weighing is to be lowered from the top of the scale 3, the fork 5 of the transport cart 4 is moved between the pedestal 16 and the grain bag 2. By inserting the grain bag into the fork, the holding action of the bag mouth by the holder 1 can be released, and furthermore, the grain bag 2 can be loaded and transported on the fork 5, and the operation is extremely simple.

(Example) Next, an example of the present invention will be described with reference to the drawings.

In this embodiment, the weighing bag of the present invention is installed below the tank 8 that stores the grains of a vertical grain sorter 7 that sorts grains such as rice and wheat into large-diameter grains and small-diameter waste grains. A device 14 is installed to bag the sorted grains.

The vertical grain sorter 7 has a vertical sorting mechanism inside a vertically elongated machine frame 9, and the grains fed from a supply chute 10 protruding from the bottom of the machine frame 9 are fed through a feed chute 10 that protrudes from the top of the machine frame 9. The grains are sorted according to their grain size while being sent to a tank 8 where the grains are raised, and the larger grains are stored in the tank 8.

Small grains, crushed grains, etc. are taken out of the machine frame 9 from the waste grain outlet 11.

Shutter 13 provided at outlet 12 of tank 8
is determined by the weight signal from the weighing device 3, which will be described later.
It is configured to operate to close the outlet 12 at a set bagging weight.

The weighing and bagging device 14 is provided with a bag opening holder 1 for holding the bag opening in an open state on top of pillars 15, 15 which are erected on the left and right sides of the measuring instrument 3.

A bag holder 16 consisting of a plurality of plates with an open upper part is installed on the weighing device 3 so that a fork 5 of a transport cart 4 can be inserted to scoop up the bags 2. On the back side of the bag holder 16, there is provided a detection tool 6 made of a plate pivoted so that it can be rotated downward by being pushed by the tip of the inserted fork 5. A wire 17 connected to the bag opening holder 1 is connected to the detection tool 6, and the wire 17 is pulled by rotating the plate downward.
