Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a coil weighing device.
[0002]
[Prior art]
Prior art related to the present applicant (Japanese Patent Laid-Open No. 10-239144) reduces the failure of the weighing machine by flattening the upper surface of the coil cradle and sticking a rubber sheet having an appropriate rubber hardness on the upper surface. Achieved.
[0003]
[Problems to be solved by the invention]
However, when used for many years, a recess is formed in the center due to plastic deformation due to deterioration of the rubber, and oil droplets from the oil coating coil accumulate in the recess. If an oil-free coil is loaded in a state where oil has accumulated, oil will adhere significantly to the oil-free coil, so it cannot be loaded as it is, and cleaning of the rubber sheet, etc. is required before loading the oil-free coil. .
An object of the present invention is to solve the above-mentioned problems and to provide a coil weighing device capable of efficiently discharging oil accumulated by dripping from a coil.
[0004]
[Means for Solving the Problems]
In order to solve the above problems, the configuration of the present invention is as follows. That is, the first configuration is formed by placing a pedestal having a peripheral wall placed on the loading body of the weighing machine and an upper surface of the cradle with a space from the peripheral wall, and cutting the lower surface. A frame having oil draining, a plurality of rubber plates disposed on the upper surface of the cradle inside the frame, and between the frame and the rubber plate and between the adjacent rubber plates, look including a plurality of partitions disposed to exist a gap, the height of the partition is to is lower than the rubber plate and the frame.
[0005]
The second configuration is that, in addition to the first configuration, two adjacent rubber plates are inclined at the top so as to form a valley.
[0006]
In the third configuration, in addition to the first configuration, in the three adjacent rubber plates, the upper surface of the rubber plate located in the center has a mountain shape, and the rubber plates located on both sides The upper surface is inclined so as to form
[0007]
In the fourth configuration, in addition to the first, second, or third configuration, the cradle has a discharge groove inside the lower portion of the peripheral wall, and has a discharge port that communicates with the groove. It is mounted on the upper surface of the cradle, avoiding the discharge groove.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below based on an embodiment shown in the drawings. 1 to 3, the cradle 2 is placed on the loading upper surface of the loading main body 1 b supported at the four corners by the load cell 1 a of the weighing machine 1. In this cradle 2, a rectangular substrate 2 a is provided with a peripheral wall 2 b, a discharge groove 2 c is formed in the substrate 2 a inside a lower portion of the peripheral wall 2 b, and a discharge port 2 d is provided in the peripheral wall 2 b in communication therewith.
[0009]
The frame 3 is placed on the upper surface of the cradle 2 with an interval so as to avoid the discharge groove 2c with respect to the peripheral wall 2b, and has an oil drain 3a formed by cutting out the lower surface. A plurality of rubber plates 4a and 4b are arranged on the upper surface of the cradle 2 inside the frame 3, and the rubber plates 4a and 4b between the frame 3 and the rubber plates 4a and 4b and adjacent to each other. The plurality of partitions 5 are arranged with a slight gap therebetween. The height of the partition 5 is lower than that of the rubber plates 4 a and 4 b and the frame body 3.
[0010]
In the three adjacent rubber plates, the upper surface of the central one is a chevron-shaped rubber plate 4a, and the rubber plates located on both sides are upper surfaces so as to form a valley with respect to the central one. Is an inclined flat rubber plate 4b.
[0011]
Then, a bar 4c or the like is laid under the flat rubber plate 4b, and an inclination is made on the upper surface of the rubber plate. The oil dripped onto the rubber plate efficiently flows into the oil passage made by the partition 5.
[0012]
Therefore, in the above description, for example, the right side of the chevron rubber plate 4a is the loading range La on which the oil-coating coil A is placed, and the left side is the loading range Lb on which the oil-free coil B is placed. The oil-coil A placed in the oil-coil loading range La moves gently in the direction of the angle rubber plate 4a due to the inclination of the rubber plate 4b, and stops near the center L between the load cells 1a and 1a. The same applies to the oil-free coil B placed in the oil-free coil loading range Lb.
[0013]
In general, the load cell type weighing machine is adjusted so that it can be measured with the highest accuracy when loaded in the center between the load cells. Therefore, in the present invention, the coil loaded at any position is located near the center L as described above. Thus, accurate weighing can be performed.
[0014]
The oil dripped from the oil coating coil A travels along the inclined upper surface of the angle rubber plate 4 a or the flat rubber plate 4 b and reaches the gap between the rubber 4 plates spread by the partition 5 and the gap between the rubber plate and the frame 3. . Then, the oil flows along the path of the gap, flows into the discharge groove 2c from the oil drain 3a, and is further discharged to the outside of the cradle 2 through the discharge port 2d. Moreover, since it arrange | positions so that the edge part of the partition 5 may not contact the edge part of the adjacent partition 5, and the frame 3, oil is easy to be discharged | emitted.
[0015]
Here, for the following reason, the thickness of the partition 5 is desirably about 5 mm or more. That is, all the oil in the gap between the rubber plates or between the rubber plate and the frame 3 is not discharged at one time, and remains in the gap or between the rubber plate and the upper surface of the cradle for each weighing. When the coil is loaded on the rubber plate, the rubber plate is compressed in the vertical direction and extended in the horizontal direction. Therefore, if there is no partition 5 or if its thickness is small, the rubber 4 stretched in the horizontal direction will be in pressure contact with each other, so that a sufficient gap is not secured in the passage of oil and remains until the previous weighing. This is because the oil rises again on the rubber plate.
[0016]
Similarly, a gap by the partition 5 is also required on the oil-free coil loading range Lb side. Without this, oil dropped from the oil-coating coil A but not reaching the discharge groove 2c rises from the gap between the rubber plates on the non-oil-coil loading range Lb side. If the thickness of the partition 5 is about 5 mm or more, even if a coil is loaded, an appropriate gap is secured and oil does not rise.
[0017]
FIG. 5 shows another embodiment, in which two flat rubber plates having inclined surfaces are arranged adjacent to each other in place of the angle rubber plate.
[0018]
The present invention is not limited to the above-described embodiments and embodiments, but includes various modifications without departing from the spirit and scope of the claims.
[0019]
【The invention's effect】
According to the first and second configurations of the present invention, by providing a gap by the partition, the oil on the rubber plate on which the coil is placed flows down from the rubber plate and accumulates between the frame body and the pedestal peripheral wall. Therefore, the surface of the rubber plate can be kept cleaner than the conventional one. For this reason, depending on the application of the coil, a sufficient effect can be exhibited without dividing the oil-coated coil loading range and the oil-free coil loading range.
According to the third configuration of the present invention, both the oil-coated coil and the oil-free coil can be loaded without cleaning the surface of the rubber plate.
According to the fourth configuration of the present invention, oil is effectively discharged to the outside through the discharge groove and the discharge port.
