Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a weighing object feeding device used for weighing grains and the like.

[Conventional technology]

Conventionally, the work of lowering a bag, etc., filled with a predetermined amount of weighing object supplied from a weighing object supply device to the ground from a platform weighing platform has been either carried out by a worker holding the bag, etc. and lowering it directly to the ground, or A person was carrying the bags and other items and transferring them onto a roller conveyor placed near the weighing stand.

[Problem that the invention attempts to solve]

However, heavy bags filled with weighing items (e.g.
Carrying a weight of 30 to 60 kg) is hard work for the worker, which reduces work efficiency, and the heavy bags, etc. that are being lifted may drop and impact the platform scale, reducing the precision of the platform scale. There were some drawbacks such as making it difficult to use.

The object of the present invention is to provide a weighing object supplying device for solving the above-mentioned problems.

[Means for solving problems]

The gist of the present invention is that a platform scale provided in a weighing object supply device, rails for guiding a transport vehicle that sandwich the platform scale from both sides, and a platform scale that is guided in an inclined position above the weighing object holder of the platform scale by the rails. The height dimension from the grounding part of the wheels of the transporting vehicle to the grounding part of the bottom is from the guide surface of the transporting vehicle guide rail on both sides of the platform scale to the receiving surface of the weighing object holder of the platform scale. When the carrier is stood up on the weighing object cradle of the platform scale, the bottom of the carrier is placed on the weighing object cradle with the wheels of the carrier floating above the rails. This is what I tried to do.

[Effect]

When the carrier is stood up on the weighing object holder, the carrier is placed on the weighing object holder. When the upright transport vehicle is tilted, the transport vehicle moves away from the weighing object holder and its wheels ride on the rails.

[Explanation of Examples]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a weighing object supplying device according to the present invention will be described based on embodiments shown in the drawings. Figure 1 shows a weighing object supply device according to the present invention (hereinafter referred to as the "proposed device")
2 is a front perspective view of the present device 1. In the figure, 2 is the main body of the device 1 of the present invention. In the main body 2, objects to be weighed, such as grains, are introduced from a feed port 3 provided on the back side of the main body 2 and guided to an upper hopper 4, and are discharged from a control valve 5 provided at the bottom of the hopper 4. It is configured as follows. The control valve 5 is opened and closed by a suitable operating means 6, and is operated by a platform scale 7, which will be described later.
When the scale weighs a desired weight, it is automatically fully closed by a signal issued by the platform scale 7. A movable platform scale 7 is mounted on the base 8 of the main body 2.
A carry-in path 9 is formed for use. Reference numerals 10 and 10 denote transport vehicle guide rails arranged to sandwich the carry-in path 9 from both left and right sides. Rail for each transport vehicle guide 1
0 has a lower horizontal portion 10a, an inclined portion 10b, and an upper horizontal portion 10c formed continuously, and
Derailment prevention walls 10a', 10b', and 10c' are provided upright on the lower horizontal portion 10a, the inclined portion 10b, and the upper horizontal portion 10c. Left and right transport vehicle guide rails 10,
10 is connected at its leading end with a connecting frame 10e for reinforcement and convenient handling. The left and right transport vehicle guide rails 10, 10 are
The lower end 10d' of the leg 10d provided at the rear end of each upper horizontal portion 10c is rotatably supported 12 on the base 8 of the main body 2, and can be rotated in the direction of arrow A after the work is completed. Then, as shown in FIG. 3, it is in the stored state. The carrier guide rail 10 is connected to the main body 2 by a connecting means 15 such as a chain so as to safely maintain the storage state. Upper horizontal portion 10 of the transport vehicle guide rails 10, 10
c, 10c and the platform scale 7 carried into the carry-in path 9.
As shown in FIG. 2, the height relationship between the bottom part 11a and the weighing object holder 7a is as shown in FIG. When stood up, the upper horizontal parts 10c, 10
The bottom part 1 of the carrier 11 is placed on the weighing object holder 7a with the wheels 11b, 11b of the carrier 11 floating from c.
1a is placed thereon.

Note that the transport vehicle guide rail 10 is not rotatably connected to the base 8 of the main body 1, and although not shown in the drawings, the transport vehicle guide rail 10 is not rotatably connected to the base 8 of the main body 1. Car guide rail 10
It goes without saying that the legs 10d of the transport vehicle guide rail 10 may be connected by being guided so as to be slidable back and forth, or the appropriate position of the carrier guide rail 10 may be removably connected to the main body 2 by appropriate means such as pinning or bolting. It is possible.

Next, a method of using the present device will be explained. First of all,
As shown in FIG. 3, the carrier guide rail 10 in the stored state is rotated to bring it into the working state shown in FIG. 1. Next, the movable platform scale 7 is moved along the carry-in path 9 to a predetermined working position. Next, the bag 14 held in a standing position by the bag holder 13 is
It is placed on the carrier 11 with its mouth open, and the carrier 11 is guided by the carrier guide rails 10, 10 and moved above the weighing object holder 7a of the platform scale 7. As shown by the two-dot chain line in FIG.
is placed in an upright position, and the carrier 11 is placed at a predetermined position on the weighing object holder 7a of the platform scale 7. Continuing further,
After opening the control valve 5 of the main body 2 and filling the bag 14 with a weighing object (material to be filled) such as grains from the hopper 4 and supplying a predetermined weight of weighing object,
The control valve 5 is automatically fully closed by the signal issued by the platform scale 7. Finally, transport vehicle 11
As shown in Figure 2, tilt it slightly backwards,
The wheels 11b of the transport vehicle 11 are connected to the transport vehicle guide rail 1.
0,10, and the transport vehicle guide rail 10,
The transport vehicle 11 is lowered to the ground along the road 10. When the weighing work is completed, the platform scale 7 is carried out and the carrier guide rail 10 is stored as shown in FIG. 3.

[Effects of this invention]

As described in detail above, the device of the present invention allows the transport vehicle to be moved from the ground to the weighing cradle of a platform scale, or The weighing object can be guided and moved safely and smoothly from the top of the platform to the ground without giving any impact to the platform scale, making it possible to maintain good accuracy of the platform scale and improve work efficiency. have an effect.
