Abstract

The present invention relates to a scale used in a food waste pay-as-you-go device, and the accuracy of the scale used here is based on the weight value that is directly related to the calculation of the discharge amount. will be. Therefore, the present inventors compensated for the problem of non-manual adjustment of the scale used in the conventional food waste collection device. By using two beam-type load cells with a control unit with low scale scale and no adjustment, no mechanical interference occurs. It is to produce a scale for pay-as-you-go equipment for discharging food waste that satisfies the legal regulations for weighing according to the manufacture of the scale and ensures accurate measurement.

Description

Scale devices use container for collecting by specific duty food garbage using a beam type loadcell}

The present invention is designed to reduce the amount of food waste by recycling the food waste that can be recycled in terms of recycling. As regards balances, the accuracy of the scales used here is very important for accuracy as it is the basis for the weight of the discharger, which is directly related to the calculation of emissions. In this regard, the present inventors devise a scale that can guarantee accurate measurement to compensate for the problem of the scale used in the conventional food waste mass-measuring device.

Currently, government offices that collect food waste and charge discharge fees are used for general single-family homes and restaurants, and the coin system using collection bags and baskets is used. Imposing a cum. The emitter not only has no food waste reduction consciousness, but also charges irrespective of the amount or weight of the discharge, and therefore has an unfair charge. Therefore, many companies have been developing and researching to develop the most reasonable pay-per-food discharging system, but it is difficult to develop a metering device that can accurately measure the amount of discharge. In the case of the scale attached to the food weight-based collection device of the registered patent 10-0927351, as shown in Figure 1, the food waste weighing scale is located on the top of the container, which is cumbersome to periodically clean the food waste attached to the measuring scale hopper. A problem with cleanliness is exposed, and in the case of the registered patent 10-0947312 illustrated in FIG. 2, a scale was manufactured using two load cells having an S shape at the bottom of the collection box. When the scale is manufactured using the S-shaped load cell, the scale is manufactured by fixing the S-type load cell 10 to the upper and lower fixing bolts 14 and 15 to the upper and lower fixing supports 8 and 9. When the load 11 is applied to (7), the scale load plate 7 rises in the direction of the counter load 12, and the offset portion 13 of the detailed view causes the offset of the weight value. This causes a reduction in weight and a variation in the weight value depending on where the collection box is placed on the weighbridge scale and where the food is being poured. To eliminate these factors and phenomena, three load cells and a summing box should be used to remove mechanical eccentricity and to adjust the dating.

Scales for food waste pay-as-you-go devices have two challenges: the tray must be made with the lowest possible height so that the bin can easily be placed on the scale and must pass the scale's production qualification standards. As for the standards for manufacturing and validating scales, the first scale running in all directions based on the center of gravity when the standard weight of the maximum capacity value of the scale is placed on the scale in the case of a newly manufactured scale, as described in the Law, Enforcement Ordinance, and Enforcement Regulation on Weighing. It is required to be within the range of error to pass the manufacturing test, and even when checking the eccentric load, it is required to be within one scale with 1/4 weight of maximum capacity. Therefore, the present invention solves the problem of weighing scales, which satisfy many legal regulations regarding weighing according to the scale production, and which many manufacturers who are developing the pay-as-you-go food dispensing device, always collect accurate and durable and practical. To develop a scale for the device.

Raise the bin on the scale tray and remove the eccentric load error caused by the location of the trash when discharging food.The scale value of the scale does not move even in the event of wind or external shock. Develop a scale for pay-as-you-go devices.

The development of this weighing scale ensures that the collection weight is placed on the weighing pan and that the same weight is indicated, and that it is an accurate emission check balance that can always obtain the same weight even if the food is poured into the collection. It will be a collection device.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings based on FIG. 4. The load cell lower fixing support 9 is placed on both sides of the scale frame 16, and the beam-type load cell 17 is placed on both sides thereof. The upper part of the load cell lower fixing bolt (15) is fixed to the upper part of the load scale (18) and the upper part of the beam scale load cell (17) is bent and fixed to fix the load plate (17). The balance was fixed with two bolts (14) to prevent shaking. In the case of the food-based dispensing device, when the container is full, it keeps the weight of about 70kg ~ 80kg. Therefore, the worker has to lower the scale pan because the container must be removed from the weighing pan by using the wheel attached to the bin. It's easy to work with. Originally, a scale using a beam-type load cell was designed to produce an electronic scale using one load cell, but the present inventors adjust the eccentric load to install the load plate 7 as low as possible so that the food waste collection box can be easily raised due to the characteristics of the pay-per-use device. By using these two beam-type load cells 17, the eccentric load of the scale can be fundamentally eliminated by developing a scale for a pay-as-you-take collection device that has a stable structure and an accurate weight value. In addition, in the electronic scale using a load cell, a warping error occurs in the process of attaching a strain gauge and a strain gauge to the load cell. As mentioned in the "problem to solve" such a deviation error, there is a process of adjusting the dating to meet the relevant law standards for weighing. In the conventional weighing scale manufacturing technology, an S-shaped load cell 10 is attached to both sides. There is no way to adjust the balance of the balance. This is because the S-shaped load cell does not have a reticle adjustment tool, and the reticle adjustment is possible only in a summing box using an external substrate. Therefore, the present inventors use the beam type load cell 17 to adjust the deviation of the balance by using a polishing wire in the reticle 22 of the beam type load cell 17 without the need for a summing box. I did it. In addition, the load cell support bent portion 19, which forms the scale load plate side surface 18 and bends the upper side once again to form the support portion of the load cell, is formed by bending both sides of the scale load plate 7 vertically. And guide bolts (20) attached to the inlet side so that the food collection container can easily enter and the back stopper bent portion (21) by bending the back of the pan vertically. The wheel of the collection container is made to stop and falling food waste does not spill on the ground. Is to create a reliable pay-as-you-go collection scale by eliminating the instability of .
