Description

[Detailed Description of the Invention] "Industrial field of application" The present invention hangs a flexible container for containing a predetermined weight of grain under tension, and stores a specific weight of grain in the flexible container. The present invention relates to a flexible container suspension device at the time of weighing, in which a tensioned suspension condition is automatically released when the flexible container is detached from the flexible container.

"Prior Art" Conventionally, in order to store a predetermined weight (for example, 1000 kg) in a flexible container while weighing carefully selected grains, the flexible container's ears mounted on the weighing machine are tensioned by a plurality of bullets. Before the present application, the suspension technology that was originally used was the National Federation of Agricultural Cooperative Associations, the 11th volume of the "Kyodo Facility Tebiki" issued by the Materials Department on January 20, 1985, P105, P106
And are well known.

"Problems to be solved by the device" By the way, in this type of conventional lifting technique, the flecon ears were hung under tension by a plurality of ammunition during the grain filling operation. When a predetermined weight (for example, 1000 kg) of grain is stored in the flexible container, the ammunition is tensioned as much as possible, and in order to carry the flexible container out of the weighing instrument, the ammunition is artificially operated from the ear of the flexible container. Even if I tried to remove it, I could not get along, so after lifting the heavy FIBC with a forklift to release the tension of the ammunition, I removed the ammunition from the ear.

Therefore, there is a problem that the work of releasing the flexible container in the suspended state is troublesome and labor saving is not possible.

The present invention, even when the flexible container is hung under a tension state by using a compression ammunition machine to perform the filling work of the grain, a predetermined weight (for example, 1000 kg) of the grain is weighed in the flexible container. An object of the present invention is to obtain a suspending device at the time of weighing in which the compressed bullet is automatically released from the tensioned state when stored and can be easily removed from the flexible container.

[Means for Solving the Problem] In order to achieve the above-mentioned object, in the flexible container suspension device at the time of weighing of the present invention, in the state of being locked by the hook plate in the hollow box body suspended on the weighing machine frame. Originally, the shaft that suspends the flexible container is pierced and supported, and the hook plate can be moved down against the elastic force of the compression ammunition together with the shaft that is pulled down by the load of the flexible container in the locked state. The locked state between the shaft and the hook plate is released by the operation of the operating lever mounted on the hook plate with the lower end edge of the elongated hole vertically provided in the hollow box.

"Operation" When attempting to fill and store a selected weight of a selected grain in a flexible container (for example, 1000 kg), first place an empty flexible container with an open upper part on the weighing machine, and When the upper end side of the hanging box is suspended on the weighing machine frame, the shaft is moved upward and the shaft is locked by the engaging action with the hook plate.

Under the above conditions, the lower end of the shaft is locked to the ear of the flexible container to suspend the flexible container. Next, if the grains selected from the supply hopper are filled into the flexible container, the schaft is pulled downward in sequence due to the increase in the grain load on the schaft as the storage capacity increases, and at the same time engages with the schaft. The hook plate in the state is also moved downward against the biasing munitions of the compression munitions, so that the flexible container can be properly suspended.

When a predetermined weight (for example, 1000 kg) of grains is filled and stored in the flexible container by the above-mentioned continuous filling and feeding action of grains,
Since the operating lever comes into a state of colliding with the lower end edge of the long hole vertically provided in the hanging box, when the grain is filled and supplied to the flexible container so that the weight becomes a predetermined weight, it is lowered by the load of the grain. The operating lever is forcibly lifted upward by the shaft, and the engagement between the shaft and the hook plate is automatically released, and the shaft is freed and lowered by its own weight. It is moved up to the starting position by the restoring force of.

Therefore, since the shaft that suspends the flexible container becomes free, the shaft that is locked to the ear of the flexible container can be easily removed.

When the plurality of suspension boxes suspending the flexible container are removed from the flexible container by the above operation, the open part of the flexible container is closed, and then the flexible container may be transported to any place by the forklift.

"Embodiment" An embodiment will be described with reference to the drawings. In Figs. 1 and 2, reference numeral 1 denotes a measuring instrument, which may have an arbitrary structure, but in the present embodiment, a load cell is used. The formula meter is illustrated. The measuring instrument 1 is provided with a substantially L-shaped measuring instrument frame 2. Reference numeral 3 denotes a flexible container for accommodating grains mounted on the weighing device 1.
An inlet 4 and an outlet 5 that can be opened and closed are provided on the upper side and the lower side. Reference numeral 6 denotes a suspending device for elastically suspending the flexible container 3 mounted on the measuring instrument 1 on the measuring instrument frame 2, and the suspending device 6 is configured as follows. That is, a hollow box body 8 and a hollow box body which are formed in a vertically long rectangular shape as a whole and have a detachable lid plate 9 mounted on one side and a hook 10 which is removably suspended on the weighing machine frame 2 on the upper side thereof. A sliding metal fitting 11 that slides in the body 8 in the vertical direction is mounted on the upper end side, and a compression ammunition machine 14 is wound between the sliding metal fitting 11 and the bottom wall 13 of the hollow box body. The movable rod 12 that has been housed and the hook member 15 of the flexible container 3 at the lower end.
It is provided with a hanging hook 16 that is locked to the shaft 17 and a shaft 17 penetratingly supported so that it can move freely in the vertical direction. A base end side of a hook plate 20 which is pressed downward by the urging elastic force of a downward-oriented bullet munitioning machine 19 attached to is pivotally attached. The free end side of the hook plate 20 engages with an annular locking groove 21 formed on the upper side of the shaft 17 in a disengageable manner to stop the vertical movement of the shaft 17. Is opened. Therefore, Shaft 17
Is in a state of being fitted into the engagement opening 22.

On the free end side of the hook plate 20, there is mounted an operating lever 24 which extends outward through a long hole 23 provided vertically in the cover plate 9 of the hollow box body 8. When the shaft 17 is lowered to the lower edge of the slot 23 due to the increased grain load that accompanies the increase in the amount of grain filled and supplied in the slot 23, the shaft 17 is lifted up by the collision action with the lower edge 25 of the slot 23. It is operated so that the engagement state between the locking groove 21 and the engagement opening 22 is automatically released. A guide groove 26 for vertically sliding the hook plate 20 vertically is provided on one side of the hollow box body 8. Reference numeral 7 is a product tank for supplying the selected grains into the flexible container 3, and the flexible container 3 is configured to accommodate, for example, 1000 kg of grains.

"Effect of the Invention" Since the present invention is configured as described above, it has the following effects. The flexible container is suspended through the shafts that are locked by the engagement operation of the hook plates, and the shafts and the hook plates are lowered against the resilience of the compression ammunition in accordance with the increase in the grain load applied to the shafts. Therefore, it is possible to hang the FIBC under proper tension at all times to efficiently fill and feed the grain of the specified weight, or when the grain of the specified weight is filled and fed into the FIBC. , The operating lever mounted on the hook plate that is lowered together with the shaft abuts against the lower edge of the long hole to move it upward, and the engagement between the engaging groove and the hook plate is automatically released to free the shaft. As it can be lowered by its own weight, the tension between the shaft and the flexible container is automatically released, and the locked state between the shaft and the flexible container is easily released with labor saving. It is possible.
