Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to the field of weighing platforms equipped with load cells constituting digital measuring instruments.

(Prior art) In the weighing platform of a conventional weighing instrument, a plurality of load cells are installed between the forehead plate and the weighing platform as sensors for measuring the load.
It becomes heavier by the weight of the weighing platform, making it inconvenient to transport, the manufacturing process is complicated, maintenance is difficult, and the weighing instrument becomes taller, making it difficult to use, and when assembled as a measuring instrument. There were defects such as the need for various small parts.

(Problems to be solved by the present invention) The present invention attaches a load cell with a screw for level adjustment directly to the back side of the flange of the forehead plate that constitutes the weighing base of the measuring instrument, and eliminates the need to attach the weighing base. This reduces the weight of the entire weighing scale, reduces the number of assembly steps, and eliminates the need for various small parts such as the weighing stand, significantly reducing production costs compared to conventional methods. By attaching the casters attached to the bottom of the platform at right angles to the side surfaces constituting the plaque, the weighing platform can be moved from a horizontal position to a vertical position. Furthermore, the measuring device was lowered to make weighing easier.

(Means for Solving the Problems) The present invention provides a plaque 1 having a square cross section and a planar housing portion 11, and a flange portion 12 of the plaque 1.
A vertical fitting part 12' is provided in which the pillars at both ends of the two separately provided fence parts 13 can be fitted and removed, and an inclined rear entrance part 2 is provided which is connected to the housing part 11. In this livestock weighing stand, a caster 8 is mounted on the side surface 10 of the forehead plate 1 at right angles to the side surface 10, and a level adjustment screw 4 is installed on the back surface 2 of the collar 12 of the forehead plate 1. This is a configuration of a weighing platform in a measuring instrument characterized by being equipped with a load cell 3 having the following structure. Alternatively, the storage portion 11 constituting the plaque 1 may be connected with the inclined rear entrance portion 2, and the fence portion may have a shape slightly lower than the height of the livestock.

(Example) Reference numeral 1 denotes a frame plate having a square cross section and constituting a weighing table a, and a plurality of load cells 3 as measurement sensors are mounted on the back surface 2 of the plate 1. Reference numeral 4 denotes level adjustment screws attached to the bottoms of all the load cells 3 attached. The function of this screw 4 will be described later. 5 is a storage box for the cable of the load cell 3 attached to the back surface 2 of the frame 1, and 6 is the back surface 2 of the frame 1.
This is a moving handle attached to the. Reference numeral 7 denotes an entrance portion formed in an inclined shape so that the livestock b constituting the plaque 1 can easily enter. Reference numeral 8 denotes moving casters that are mounted parallel to the horizontal storage portion 11 formed between the side portions 10 constituting the frame 1 and at right angles to the side portions 10. As a general rule, the caster 8 is mounted so as to protrude from the side surface 10 at all times as shown in the drawings, but the present invention is not limited thereto. Although the caster 8 is shown mounted only on one side surface 10 in the drawing, it may be mounted on both the left and right side surfaces 9 and 10, respectively. 12 is both left and right side parts 9,1
A flange portion 12 is formed by extending above 0, and a vertical fitting portion 12' is formed in this flange portion 12. 13
has a length comparable to the length of the collar part 12, and the livestock b
In particular, two shelves 13 having a shape slightly lower than the height of the pig are formed and assembled so as to be vertically fitable and detachable on the forehead plate 1. The height of both shelves 13, 13 is such that when assembled as shown in the drawing, the back of the driven livestock b will protrude slightly. 1
4 is livestock b driven into the front part of both shelves 13, 13
This is a front shelf part that is attached between both shelf parts 13, 13 so that it can be inserted and removed and opened and closed freely to prevent the front part from protruding. A rear shelf part 15 is attached to both shelf parts 13, 13 on the opposite side of this shelf part 14 so as to be able to be fitted in and taken out and opened and closed. 16 is both shelves 1
4.15 hinges for opening and closing. When the weighing is finished, the front shelf 14 is opened and the livestock b is expelled from the weighing platform a. When you want to weigh the next livestock b,
It is sufficient to close the front shelf section 14 again and open and close the rear shelf section 15 on the other hand.

(Function) Next, the function of the present invention will be explained as follows. In order to weigh livestock b, weighing platform a is transported to the livestock barn and placed on the floor. Whether or not the placed weighing platform a is horizontal is checked by rotating the level adjustment screw 4 attached to the bottom of the load cell 3. When rotating the screw 4, the scale table is not attached to the load cell 3 as in the conventional case, so the operation can be performed extremely easily. Furthermore, since a weighing stand is not attached, it is extremely easy to carry.

As mentioned above, once the leveling of weighing platform a is completed,
The two shelf parts 13, 13 are sequentially made vertical and inserted into the insertion part 12 to be assembled. The front and rear shelf sections 14 and 15 are rotatably attached to the above-mentioned shelf sections 13 and 13. After the assembly is completed, inside the assembled shelf,
Only the rear shelf 15 is opened and livestock b is driven into it. Since the platform 7 is inclined during this driving, the livestock b can smoothly advance and be accommodated without tripping. In the present invention, the weight value of the livestock b placed on the plaque 1 is detected by the change in the output voltage generated by the load cell 3.

Furthermore, when you want to transport it for storage or weighing, grasp the moving handle 6, ground the casters 8 to the floor, raise the weighing platform a from a horizontal state to a vertical state, and move it forward toward the weighing location. This allows for extremely smooth movement to the weighing location.

(Effects) (1) This invention attaches a load cell with a screw for level adjustment directly to the back side of the flange of the forehead plate that makes up the weighing platform of the scale, and also attaches the caster at right angles to the side surface that makes up the forehead plate. By mounting the weighing scale in the shape of the scale, it becomes unnecessary to install a weighing platform, the entire weighing instrument is lowered to make it easier to weigh livestock, etc., and the weighing platform can also be moved from a horizontal position to a vertical position. This has the advantage of reducing the location ratio at storage locations.

(2) Furthermore, since a scale stand is not required, it has many advantages over conventional digital scales, such as easier and more convenient maintenance.

(3) Additionally, as an accessory to the present invention, a sloping platform is formed at the rear of the plaque, so livestock can be driven smoothly without tripping, and the height of the vertically assembled shelf is Since the height is formed and assembled to be slightly lower than the height of the livestock, it is easy to drive the livestock, and the livestock that has been driven in are housed in a flat state without any resistance. Therefore, it has the advantage of being easy to measure.
