Conventional technology Conventionally, this type of bag holding device was developed in 1983.
No. 13415, etc., which hold the upper edges of both sides of the bag with clamps such as clips.

Problems to be Solved by the Invention In the prior art as described above, when holding a bag, one hand holds the top edge of one side of the bag and the other hand operates a clip to hold it, and then Since the upper side edges are held in the same manner, the operation is not only complicated, but also it is difficult to hold the bag in an accurate posture because both sides of the bag are held separately. This invention aims to solve the above-mentioned drawbacks and to hold the bag in an accurate position with simple operation.

Measures to solve the problem A pair of upright pillars 1, 1 upper mounting parts 2, 2
fixed clamping pieces 3, 3 that detour upward and hang inward; a rotating arm 4 that is pivotally supported at the lower part of the mounting parts 2, 2 and extends obliquely upward toward the clamping pieces 3, 3; The upper edges of both sides of the bag 6 are held by clamping rolls 5, 5 which are pivoted at the tips of the rotating arms 4, and the lower surfaces of the rotating arms 4, 4 are curved to protrude downward. , 4 and the outer periphery of the lower surface of the clamping rolls 5, 5 are formed approximately in the tangential direction of the outer peripheries of the clamping rolls 5, 5.

Function When attaching the bag 6 to the bag holding device, open the bag mouth and hold the upper edges of both sides of the bag 6 with your thumb and index finger, and place the tips of the index fingers of both hands on the lower surface of the rotating arms 4, 4. While moving the rotating arms 4, 4 along the protruding curved surface, push the rotating arms 4, 4 slightly upwards around the pivot portion, and then push the rotating arms 4, 4 with your index finger.
The upper edges of the bag 6 are held between the clamping rolls 5, 5 and the fixed clamping pieces 3, 3 by continuously moving the bag 6 from the lower surface along the outer periphery of the clamping rolls 5, 5.

Effects of the invention Since this invention is constructed as described above, when attaching the bag to the bag holding device, there is no need to open/close operations using clips or the like as in the past, and the user can hold the upper edges of both sides of the bag 6 with both hands. By a simple operation of moving the tip of the index finger from the protruding curved surface of the lower surface of the rotating arms 4, 4 along the continuous outer peripheral surface of the clamping rolls 5, 5, it is possible to hold the upper edges of both sides of the bag 6. can maintain an accurate posture. Further, the lower surfaces of the rotating arms 4, 4 are curved to protrude downward, and the intersections between the rotating arms 4, 4 and the outer peripheries of the lower surfaces of the clamping rolls 5, 5 are approximately tangential to the outer peripheries of the clamping rolls 5, 5. Because of this, the tip of the index finger holding the upper edges on both sides of the bag 6 can be smoothly moved along these edges, and work can be performed without damaging the fingertip.

Embodiment Next, an embodiment of the present invention will be described based on the drawings.

In this embodiment, a weighing device 9 for measuring weight is installed below a storage tank 8 of a vertical grain sorter 7 that sorts grains such as rice and wheat into large-diameter regular grains and small-diameter waste grains.
The bag holding device 10 of the present invention is installed on the measuring device 9, and grains are supplied from the storage tank 8 into the empty bags 6 held by the bag holding device 10 for bagging. .

The scale 9 is electrically connected to a solenoid 13 that operates a shutter 12 provided at the supply port 11 of the storage tank 8, and the shutter 12 is closed according to the measured weight of the scale 9, and grains are removed every predetermined weight. It is configured to bag grains. The weight measured by the scale 9 is displayed on a display panel 28 provided on the front of the storage tank 8.

Reference numeral 14 denotes a support plate of the bag holding device 10, and the front and rear bent parts 15, 15 are fitted and fixed to the front and rear sides of the measuring instrument 9 from above, and a pair of left and right supports are provided on the supporting plate 14. The tubes 16, 16 are attached. or,
The support columns 1, 1 are inserted into the support tubes 16, 16 so as to be vertically adjustable, and can be fixed with bolts 17.

Attachment parts 2, which have insertion holes 18, 18 larger than the outer diameter of the columns 1, 1 in the upper parts of the columns 1, 1;
2 is loosely fitted, and a spring 1 is provided between the lower surface of the mounting portions 2, 2 and the upper surface of the support tubes 16, 16.
9 and 19 are intervened to urge the mounting portions 2 and 2 upward. Numerals 20 and 20 are retaining nuts, and 21 is a connecting rod that connects the intermediate portions of the support tubes 16 and 16, and is curved toward the rear to hold the back surface of the bag 6.

Reference numeral 22 denotes a connecting rod that connects the left and right mounting parts 2, 2, and is curved toward the rear from the back of the mounting parts 2, 2.

At the lower part of the support plate 23 that is attached to the mounting parts 2, 2 and detours upward and hangs inward, the support plate 23
Fixed clamping pieces 3, 3 are integrally provided with wider widths, hanging down, and bending their lower portions inward.

A boss portion 24 is formed at the lower part of the mounting portions 2, 2,
A shaft 25 fixed to the bases of the rotating arms 4, 4 is pivotally supported within the boss portion 24, and the front portion of the shaft 25 is bent and extended outward to form an operating lever 26.

The rotating arm 4 is a fixed clamping piece 3 located above.
A clamping roll 5 made of an elastic material is rotatably mounted on the tip of the clamping roll 5, which contacts the clamping piece 3 at an angle. Furthermore, the lower surface of the rotating arm 4 is curved and protrudes downward, and the intersection with the outer periphery of the lower surface of the clamping roll 5 is formed to substantially coincide with the tangential direction of the outer periphery of the clamping roll 5. Reference numeral 27 is a winding spring, which holds the rotating arm 4 between the rolls 5
It is lightly biased toward the side.

Further, the holding portion of the bag 6 by the clamping piece 3 and the clamping roll 5 is positioned below the mounting portion 2 so that the tilting of the mounting portion 2 loosely fitted to the support 1 can be corrected by the weight of the grains in the bag 6. It is configured.

Next, the state of use in this embodiment will be explained. First, when attaching the empty bag 6 to the bag holding device 10, hold the upper edges of both sides of the bag 6 between your thumb and index finger with the bag mouth open, and then place the tip of your index finger on the curved bottom surface of the rotating arm 4. While moving it along the surface, push it up slightly to release the rotating arm 4 from the spring 27.
Rotate upwards around the shaft 25 against the rotational force to slightly open the gap between the clamping piece 3 and the clamping roll 5, and then move your index finger along the outer periphery of the clamping roll 5, which smoothly continues with the lower surface of the rotating arm 4. , position the upper edges of both sides of the bag 6 between the clamping roll 5 and the clamping piece 3, and pulling out the index finger upward, the rotation arm 4 is rotated downward by the spring 27 and the clamping piece 3 and Both upper edges of the bag 6 are held between the clamping rolls 5. In addition,
When the empty bag 6 is held, the vertical positions of the columns 1, 1 with respect to the support cylinders 16, 16 are adjusted so that the bottom of the bag lightly contacts the upper surface of the support plate 14 on the measuring device 9, or floats thereon.

Next, the shutter 12 of the storage tank 8 is opened to supply the grains into the bag 6. At this time, the bag 6 is almost suspended in the air, so that every corner of the bottom of the bag is filled and a certain amount is stored. Then, the weight of the grain causes the attachment part 2 to descend along the supports 1, 1 against the spring 19, and the bag 6 held thereon is placed on the scale 9 to accurately measure its weight. . Note that when the mounting parts 2, 2 are lowered, the insertion holes 18, 2 of the mounting parts 2,
18 is formed relatively larger than the outer diameter of the pillars 1, 1, so there is no possibility of twisting, etc.
Moreover, the connecting rod 22 between the mounting parts 2, 2 allows the left and right mounting parts 2, 2 to be lowered stably.

Furthermore, since the attachment part 2 is located above the bag holding part formed by the clamping piece 3 and the clamping roll 5, even if the attachment part 2 tilts with respect to the support 1, the grains in the bag 6 held The tilting can be modified by weight.

When a predetermined weight of grain is fed into the bag 6, the solenoid 13 is energized by a measurement signal from the scale 9, and the shutter 12 is closed.

Next, when the operating lever 26 is rotated in the direction of arrow A, the rotating arm 4 is rotated upward, and the clamping roll 5 pivotally supported at the tip of the rotating arm 4 can be separated from the clamping piece 3. In this state, the bag 6 is removed from the holding part and taken down from the measuring device 9 to complete the bag filling.
