[Brief explanation of the drawings]

[0009] [Figure 1] Front view of embodiment 1 of the present invention [Figure 2] Side view of embodiment 1 of the present invention [Figure 3] Plan view of embodiment 1 of the present invention [Figure 4] FIG. 1 is an external view showing an example of the use state of embodiment 1 of the present invention. [Figure 5] FIG. 1 is an external view showing an example of the use state of embodiment 1 of the present invention. [Figure 6] 1 is a perspective view of the second embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0010] The basic structure of this device consists of a sieve body, a frame body surrounding it, support legs that support them, and casters with stoppers attached to the lower ends of the support legs that allow them to be moved and fixed. Therefore, the sieve body should have holes that allow the waste of the size to be separated to pass through and remain, and examples include mesh netting, punched metal, or grit, or a cross-arrangement of rods or long plates. The material of the sieve body may be metal such as stainless steel, iron, or aluminum, or polymer resin such as nylon resin, polycarbonate resin, or fluororesin, or may be wood or bamboo. The frame provided on the periphery of the sieve body has the function of strengthening the sieve body and also the function of preventing waste from flying out of the sieve body when separating the waste. In addition, it is possible to attach support legs that support the frame body. The height of the support legs is determined according to the working position of the worker who stands around the sieve body to perform the sorting work (see Figure 5), but a telescopic type may also be used. The material may be metal, resin, wood, or bamboo.

[0011] A caster with a stopper is attached to the lower end of the support leg. This allows the sorting table of the present invention to be moved to a required location at any time for sorting work. It is also preferable that a bag be detachably attached to the outer surface of the frame. A plurality of bags may be provided to separately store dangerous items such as batteries and blades. A partition may be provided inside the bag. Furthermore, it is preferable to place a storage box on the outside of the support legs of the sorting table, and to place glass bottles such as liquor bottles, beer bottles, whiskey bottles, etc., and metal tableware such as pots and frying pans, which have been visually picked up and sorted by workers on the sieve body, into the storage box. It is preferable to provide a moving belt conveyor below the sieve body. During the sorting process, waste that passes through the sieve body and falls to the bottom is placed on a belt conveyor and transported forward. The waste placed on the belt conveyor and transported forward is then loaded onto a collection vehicle and transported to another location. In addition, magnets may be attached to the pulleys of the belt conveyor to add magnetic separation effect.

[0012] Next, the separation process will be described. For example, when a truck carrying waste arrives at the factory, the mobile sorting platform of this invention is moved there, and workers stand around to sort it. When the waste is spread on the sieve, small pieces of glass and other debris that pass through the sieve fall onto the conveyor, are transported forward, and are collected in a waste collection box. In addition, bottles, metal tableware, cooking utensils, and other waste that remain on the sieve are placed in a waste collection box located on the outside of the support legs, and batteries, blades, etc. are placed in a storage bag. When the work is completed, the sorting table, belt conveyor, waste storage box, and waste collection box are moved to a different location where they will not get in the way. [Example]

[0013] An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of embodiment 1 of the present invention, FIG. 2 is a side view of embodiment 1, FIG. 3 is a plan view of embodiment 1, FIG. 4 is an external view showing an example of how embodiment 1 is used, and FIG. 5 is an external view showing an example of how embodiment 1 is used. FIG. 6 is a perspective view of a second embodiment of the present invention. First, the first embodiment will be described below. As shown in Figures 3 to 5, the mobile waste sorting table of this embodiment of the invention is configured as a frame body 3 having a rectangular parallelepiped body made up of left and right side walls 3a, 3a', a front wall 3b, and a rear wall 3b'; a sieve body 2 having a large number of sieve holes 7 formed by a plurality of round bars 5 provided on the inner surface of the frame body 3 in the left-right direction with ends thereof in contact with both side walls 3a, 3a', and a plurality of plates 6 provided on the inner surface of the frame body 3 in the front-rear direction with ends thereof in contact with the front wall 3b and the rear wall 3b'; Support legs 8 are vertically attached to the four corners of the frame body 3; A caster 9 with a stopper is provided at the lower end of the support leg 8; and a holding plate 10 installed between each of the support legs 8, 8.

[0014] It should be noted that a container for storing separated waste can be placed on the plate member 4. In this embodiment, the sieve body 2 has a sieve opening 7a in the center that is small, and sieve openings 7b at the front and rear of the center that are large. This is because it is adjusted to the size of the waste that is dropped into the sieve body 2. In addition, to make it easier for workers to separate the waste, the sieve body 2 is 1500 mm wide and 1500 mm deep. Although it is assumed to be a rectangular parallelepiped of 1800 mm, it is not limited to this size. Reference numeral 8 denotes support legs provided at the four corners of the frame body 3, 9 denotes casters provided on the support legs 8, and 10 denotes a holding plate provided between the support legs. The support legs 8 are set at a height that allows workers S1 and S2 to easily perform sorting work.

[0015] 4 and 5 show one example of the use state of the mobile waste sorting table of the first embodiment of the present invention. FIG. In FIG. 4, 20 denotes a belt conveyor, and 21 denotes a waste collection box for collecting waste that has fallen onto the belt conveyor 20 from the sieve holes 7 of the sieve body 2 and been sent to the end thereof. In FIG. 5, 30 denotes a waste collection bag, and 31 denotes fixtures for detachably attaching the waste collection bag to the side walls 3 a , 3 a ′, front wall 3 b and rear wall 3 b ′ of the frame 3 of the sieve body 2 . When the mobile waste sorting table of embodiment 1 of the present invention is in use, a magnetic plate is used.

[0016] Next, the waste separation work performed by a worker will be described with reference to FIGS. Step 1 The workers S1 and S2 move the mobile waste sorting table 1 onto the belt conveyor 20 so as to straddle the belt conveyor 20. Step 2 The worker places the waste on the side wall 3a of the frame 3 of the sieve 2 of the mobile waste sorting table 1. Attach the collection bag 31. Step 3 The worker operates the belt conveyor 20. Step 4 A worker stands next to the mobile waste sorting table 1 in a position that allows for sorting, and sorts the waste (e.g., cans, spray cans, frying pans, iron products, ceramics, bottles, glasses, cups, etc.) collected from commercial buildings, factories, homes, etc. that is dropped onto the sieve body 2 of the mobile waste sorting table 1 from a mobile vehicle, etc., and collects the sorted waste into containers, waste collection bags 31, or waste storage boxes 40. Small waste materials that fall from the sieve body 2 of the mobile waste sorting table 1 onto the belt conveyor 20 are sent to a waste collection box 21 and collected. Step 5 Once workers have finished collecting the waste separated in step 4, A20 will cease operation. Step 6 The worker moves the waste sorting table 1, the belt conveyor 20, the waste collection box 21, and the waste storage box 40 to another location where they will not interfere with the work.

[0017] FIG. 6 is a perspective view of a second embodiment of the present invention. The difference between this embodiment and the first embodiment of the present invention is that the plate members 4 provided in contact with both side walls 3a on the inner surface of the sieve frame body 3, which is made of a rectangular parallelepiped body in the first embodiment of the present invention, are parallel and allow a waste collection container to be placed on them, whereas the plate members 14 in the second embodiment are inclined downward toward the inside of the both side walls 3a. As a result, waste that does not need to be separated by workers slides down the plate member 14 and falls from the sieve body 2 onto the belt conveyor 20, where it is collected in the waste collection box 21.
