[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-66623 Summary of the Invention [Problem to be solved by the invention]

[0004] Plastic products such as sheets and tapes used for protection at building demolition sites and new construction sites are disposed of as waste plastics, but because plastic products are bulky, in order to reduce disposal and transportation costs, it is conceivable to reduce the volume as much as possible using a compressor such as that described in Patent Document 1. However, the compressor described in Patent Document 1 requires opening and closing doors and inlets to load and unload waste before and after volume reduction, making it difficult to quickly reduce the volume of large amounts of waste (plastic products, etc.).

[0005] An object of the present invention is to efficiently reduce the volume of waste. [Means for solving the problem]

[0006] The present invention is a compressor that compresses waste stored in a cart by lowering a compression plate while installed on an installation surface, and is equipped with a base portion that is placed on the installation surface, a compression portion having a compression plate and a moving mechanism that moves the compression plate in an up and down direction, and a support portion that extends upward from the base portion and supports the compression portion, and the base portion is provided with a riding surface on which the wheel portion of the cart rides. [Effects of the Invention]

[0007] According to the present invention, waste volume reduction treatment can be carried out efficiently. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, a compressor and a carriage used in the compressor according to an embodiment of the present invention will be described with reference to the drawings.

[0010] First, a compressor 100 according to an embodiment of the present invention will be described with reference to Fig. 1 to Fig. 4. Fig. 1 is a front view of the compressor 100, Fig. 2 is a left side view of the compressor 100, Fig. 3 is a cross-sectional view showing a cross section of a compression plate 31 taken along line AA in Fig. 1, and Fig. 4 is an enlarged cross-sectional view showing a cross section taken along line BB in Fig. 3.

[0011] The compressor 100 is a device that compresses waste W stored in a cart 50 (described below) by lowering a compression plate 31 while installed on an installation surface 1, and is used, for example, to reduce the volume of waste W such as sheets and tapes used for protection at building demolition sites or new construction sites.

[0012] 1 and 2, the compressor 100 includes a base 10 placed on an installation surface 1, a compression unit 30 having a compression plate 31 and a movement mechanism 32 that moves the compression plate 31 up and down, and a support 20 that extends upward from the base 10 and supports the compression unit 30. The waste W that is reduced in volume by the compressor 100 is not limited to plastic products such as sheets and tapes, but may be any waste W that has a relatively low compressive strength and can be reduced in volume with a compressive load of about several hundred kg, such as used cardboard or paper products.

[0013] The base portion 10 has a pair of rail portions 11 that are placed on an installation surface 1 such as a floor of a building, and a connecting portion 15 that connects the pair of rail portions 11 and the support portion 20.

[0014] The rail portion 11 is a member having a substantially L-shaped cross section, which is a combination of a first flat plate 11a provided along the installation surface 1 and a second flat plate 11b extending substantially perpendicular to the installation surface 1, and the second flat plate 11b is joined to a connecting portion 15 by welding or the like. As shown in Fig. 1, a pair of rail portions 11 are provided, with the connecting portion 15 sandwiched between the respective second flat plates 11b.

[0015] The upper surface of the first flat plate 11a, i.e., the surface opposite to the surface in contact with the installation surface 1, is a riding surface 12 on which the wheel parts 51 of the cart 50 described below ride up, and the riding surface 12 is provided with wheel stops 13 as movement limiting parts that limit the movement of the cart 50. As a result, the cart 50 that rides up on the riding surface 12 is stopped at a predetermined position. In addition, since the load when the waste W is compressed by the compression plate 31 acts on the first flat plate 11a, whose upper surface is the riding surface 12, via the cart 50, the first flat plate 11a generates a reaction force against this load, as described below.

[0016] In addition, the movement restriction section that restricts the movement of the trolley 50 is not limited to the wheel stopper 13 provided on the rail section 11, but may be any member that restricts the movement of the trolley 50 when it comes into contact with it, and may also be a member provided on the connecting section 15 or the support section 20.

[0017] The size of the gap between the pair of rail portions 11 is set to match the gap between the wheel portions 51 attached to the carriage 50. Therefore, the movement of the carriage 50 that has climbed onto the climb-up surface 12 is guided by the second flat plates 11b of each rail portion 11 until it is restricted by the wheel stoppers 13. Note that the connecting portion 15 may be provided with a mechanism that can change the size of the gap between the pair of rail portions 11. Furthermore, a reinforcing member that connects the rail portions 11 together may be provided between the pair of rail portions 11, separate from the connecting portion 15.

[0018] In this way, the pair of rail portions 11 are members that generate a reaction force when the waste W is compressed by the compression plate 31 and also function as guide members that guide the movement of the dolly 50.

[0019] 1, a gap G1 of a predetermined size is provided between the connecting portion 15 of the base portion 10 and the installation surface 1. This gap G1 is provided to allow for the insertion of the fork portion of a lifting device such as a hand pallet used when transporting the compressor 100.

[0020] As described above, compressor 100 can be easily transported manually using a lifting device such as a hand pallet. As shown in FIGS. 1 and 2, compressor 100 is transported with compression plate 31 in the lowest position. In this state, compressor 100 has an overall height of 2 m or less, an overall width (length in the direction in which the pair of rail portions 11 are aligned) of 900 mm or less, and a depth (length in the direction in which rail portions 11 extend) of 1300 mm or less. This allows compressor 100 to be transported within a building using a typical elevator installed in the building. The dimensions of compressor 100 are not limited to these ranges. For example, compressor 100 may have an overall height exceeding 2 m, an overall width exceeding 900 mm, or a depth exceeding 1300 mm. However, to improve transportability, it is preferable that compressor 100 be compact.

[0021] Therefore, by placing compressors 100 on each floor of a building that is being demolished or constructed, it becomes possible to reduce the volume of waste W generated on each floor on the spot, and since there is no need to collect waste W that has not been reduced in volume in a designated area on the first floor, for example, the efficiency of transporting waste W can be improved.

[0022] The compression plate 31 that compresses the waste W is a smooth, approximately square plate-shaped member made of plywood such as plywood. As shown in FIGS. 3 and 4, it has a flat lower surface 31c and upper surface 31d, and a through-hole 31a in the center through which the lower end of the rack shaft 33 is inserted. By forming the compression plate 31 from plywood rather than steel, the compressor 100 can be made lighter and the load on the movement mechanism 32 and operators when moving the compression plate 31 up and down can be reduced. The material of the compression plate 31 is not limited to plywood and can be any material that can withstand compression strength. For example, it can be a steel plate or a resin plate such as PEEK. However, it is preferable to use a material that can reduce the manufacturing cost of the compression plate 31 and make the compression plate 31 lighter.

[0023] 3, all corners 31b of the compression plate 31 are rounded, and as shown in Fig. 4, the edge of the lower surface 31c, which is the corner formed between the lower surface 31c and the side surface 31e, and the edge of the upper surface 31d, which is the corner formed between the upper surface 31d and the side surface 31e, are also rounded around the entire periphery. In this way, all corners formed on the compression plate 31 are rounded, and the compression plate 31 has a shape that does not catch on the outer surface.

[0024] Therefore, for example, as in the modified example shown in Fig. 9 described later, even if a plastic bag for enclosing the waste W is provided inside the cart 50, it is possible to prevent the bag from being torn by the compression plate 31 getting caught on it. In order to reliably prevent the bag from being torn by the compression plate 31 getting caught on it, it is preferable to make the outer dimensions of the compression plate 31 approximately 100 mm smaller than the dimensions of the opening of the cart 50. The compression plate 31 can be replaced as needed depending on the size of the opening of the cart 50.

[0025] The moving mechanism 32 is a well-known mechanism equipped with a rack and pinion mechanism and a one-way clutch mechanism for moving the compression plate 31 in the vertical direction via the rack shaft 33, and is provided with a push-down lever 34 used to push the compression plate 31 downward, as well as a position adjustment handle 35 used to adjust the position of the compression plate 31 in the vertical direction.

[0026] Specifically, the position of the compression plate 31 is adjusted from the initial position to the compression start position by turning the position adjustment handle 35, and then the push-down lever 34 is moved up and down to move the compression plate 31 in the direction (downward) to compress the material to be compressed (waste W). After compression is completed, the position of the compression plate 31 is returned to the initial position by turning the position adjustment handle 35 again.

[0027] The compression unit 30, which is mainly composed of the compression plate 31, the rack shaft 33, and the moving mechanism 32, is supported by the support unit 20 which extends upward from the base unit .

[0028] The support portion 20 has a support pillar 21 whose lower end is connected to the connecting portion 15 of the base portion 10 and extends in the vertical direction, and a cross portion 22 which extends from the upper end of the support pillar 21 approximately parallel to the rail portion 11 and has a compression portion 30 attached to its tip.

[0029] In this way, the compressor 100 of this embodiment is formed by integrating a base portion 10 on which the cart 50 rides and a compression portion 30 that compresses the waste W stored in the cart 50 via a support portion 20.

[0030] The compressor 100 further includes a plate-shaped back plate portion 40 attached to the support column 21 of the support portion 20 .

[0031] The back plate portion 40 is a plate provided to cover the gap formed between the compression plate 31 and the cart 50 riding on the riding surface 12, and is made of plywood such as plywood or plywood such as plywood similar to the compression plate 31. Note that the material of the back plate portion 40 is not limited to plywood or the like, and may be, for example, a steel plate or a resin plate such as PEEK, but it is preferable that the material be one that can keep the manufacturing cost of the back plate portion 40 low and make the back plate portion 40 lightweight.

[0032] The back plate portion 40 is attached to the support column 21 in an inclined state so that the distance from the support column 21 to the upper end is longer than to the lower end, and is arranged in a position where it can cover, on the support portion 20 side, the gap formed between the compression plate 31 in a position before compressing the waste W and the cart 50 riding on the riding surface 12, as shown in Fig. 7 described later. The specific installation position of the back plate portion 40 will be described later.

[0033] By placing the back plate portion 40 in such a position, it is possible to prevent the waste W from spilling out onto the support portion 20 side when the waste W is put into the cart 50 or when the waste W is compressed.

[0034] Next, a description will be given of a bogie 50 used in the compressor 100 according to the embodiment of the present invention with reference to Fig. 5 and Fig. 6. Fig. 5 is a cross-sectional view showing a cross section of the bogie 50 taken along line CC in Fig. 6, and Fig. 6 is a top view of the bogie 50.

[0035] The trolley 50 comprises four wheel sections 51, a rectangular bottom plate section 53 to the underside of which the wheel sections 51 are attached, four side plate sections 54, 55 standing upright from the four edges of the bottom plate section 53, and a storage space 56 formed by the bottom plate section 53 and the side plate sections 54, 55.

[0036] The wheel units 51 are so-called casters, and are attached to the four corners of the underside of the bottom plate unit 53. All of the wheel units 51 may be swivel casters whose orientation is not fixed, or two of the four wheel units 51 may be fixed casters whose orientation is fixed. Note that four or more wheel units 51 may be provided.

[0037] The side plate portions 54, 55 are supported by pillars (not shown) erected at the four corners of the bottom plate portion 53, and as shown in Figure 5, are composed of a pair of first side plate portions 54 installed opposite each other and a pair of second side plate portions 55 installed opposite each other.

[0038] The pair of first side plate portions 54 and the pair of second side plate portions 55 have different heights from the bottom plate portion 53, and the first height H1 of the first side plate portion 54 is set to be a predetermined height, for example, about 200 mm, higher than the second height H2 of the second side plate portion 55. In other words, of the side plate portions 54, 55, the upper ends of the pair of first side plate portions 54 that are arranged opposite each other are positioned vertically higher than the upper end of the other side plate portion, the second side plate portion 55.

[0039] Specifically, as shown in FIG. 7 , the first height H1 of the first side plate 54 is set high so as to reduce the gap between the compression plate 31, which is in a position before compressing the waste W, and the first side plate 54 of the cart 50 riding on the riding surface 12. Setting the first height H1 of the first side plate 54 high in this manner prevents the waste W from spilling over the first side plate 54 when the waste W is loaded into the cart 50 from the lower second side plate 55 side or when the waste W is compressed. To prevent the waste W from spilling over, it is preferable to set the first height H1 of the first side plate 54 as high as possible. For example, the first height H1 may be set 200 mm or more higher than the second height H2 of the second side plate 55. However, when a plastic bag for enclosing the waste W needs to be provided inside the cart 50, as in the modified example shown in FIG. 9 , the first height H1 of the first side plate 54 is limited according to the shape of the bag.

[0040] 7, the second height H2 of the second side plate portion 55 is set low so that the waste W can be easily and smoothly loaded into the cart 50 through a gap formed between the compression plate 31, which is in a position before compressing the waste W, and the second side plate portion 55 of the cart 50 that has climbed onto the climb-up surface 12. By setting the second height H2 of the second side plate portion 55 low in this way, the work of loading the waste W into the cart 50 can be easily performed, and the work of attaching the lashing string 57, which will be described later, to the inside of the storage space 56 can also be easily performed.

[0041] The storage space 56 formed by the bottom plate portion 53 and the side plate portions 54, 55 is a cubic space, and a fastening string 57 is provided within the storage space 56 to fasten the waste W stored within the storage space 56.

[0042] The lashing string 57 is a so-called vinyl string made of polypropylene, and is attached with tape or the like to the second side plate 55 or the bottom plate 53 so that both end portions 57b, 57c are pulled out to the outside of the storage space 56 and the approximate center portion 57a ​​is positioned between the waste W and the bottom plate 53. The lashing string 57 is not limited to a vinyl string and may be, for example, a lashing belt with a buckle.

[0043] As shown in Figure 7 described below, when the trolley 50 rides up on the riding surface 12, both ends 57b, 57c of the lashing cord 57 move upward along the second side plate portion 55 on the side opposite the support portion 20 across the storage space 56, and then the one end 57b, which is pulled out to the outside of the storage space 56, moves upward along the second side plate portion 55 on the support portion 20 side, and then is pulled out to the outside of the storage space 56, shorter than the other end 57c, which moves upward along the second side plate portion 55 on the support portion 20 side, and then is pulled out to the outside of the storage space 56.

[0044] Next, a description will be given of a volume reduction process for the waste W performed using the above-mentioned compressor 100 and the above-mentioned dolly 50 with reference to Figures 7 and 8. Figures 7 and 8 show a state in which the dolly 50 is installed on the compressor 100, and the dolly 50 is shown in cross section to make it easier to understand the state inside the storage space 56.

[0045] First, as shown in Fig. 7, the cart 50 is placed on the compressor 100. The cart 50 may be one in which the storage space 56 is empty, or one in which a certain amount of waste W has already been stored in the storage space 56.

[0046] Specifically, after the wheel unit 51 rides up onto the ride-on surface 12 (the upper surface of the first flat plate 11a) of the base unit 10, the wheel unit 51 is guided by the second flat plate 11b and abuts against the wheel stopper 13, restricting movement toward the support unit 20, thereby placing the cart 50 in a state where it is installed on the compressor 100. Note that the rotation of the wheel unit 51 may be locked to ensure that the cart 50 is stopped. Furthermore, when installing the cart 50 on the compressor 100, the compression plate 31 is moved in advance to a predetermined height, which is its initial position, by turning the position adjustment handle 35.

[0047] After the cart 50 is placed on the compressor 100, the waste W is then put into the storage space 56.

[0048] The waste W is loaded into the storage space 56 from the opposite side of the cart 50 to the support part 20, through the gap between the compression plate 31, which is in its initial position, i.e., the position before the waste W is compressed and is in its specified position when the waste W is loaded, and the second side plate part 55 of the cart 50 that has climbed onto the climbing surface 12. In order to prevent the compression plate 31 from interfering with the loading of the waste W, it is preferable to set the initial position of the compression plate 31 as high as possible, for example, to a height at which the upward movement of the compression plate 31 is restricted by the moving mechanism 32.

[0049] As described above, the gap between the compression plate 31 and the first side plate portion 54 is narrowed by increasing the first height H1 of the first side plate portion 54, and the gap between the compression plate 31 and the second side plate portion 55 on the support portion 20 side is covered by the back plate portion 40 attached to the support portion 20, so that when waste W is put into the storage space 56, the waste W is prevented from overflowing onto the first side plate portion 54 side or the support portion 20 side.

[0050] In order to reliably cover the gap formed between the compression plate 31 and the second side plate 55 on the support unit 20 side, the back plate 40 is attached to the support unit 20 in an inclined state so as to be located on a line L1 connecting the end of the compression plate 31 on the support unit 20 side and the upper end of the second side plate 55 on the support unit 20 side in a side view, as shown in FIG. 7, or in a state parallel to the line L1. The back plate 40 is also arranged in an area that does not hinder the movement of the compression plate 31 and the carriage 50. An adjustment mechanism may be provided between the support unit 20 and the back plate 40 to adjust the inclination angle and installation height of the back plate 40.

[0051] By preventing the waste W from overflowing in this way, even if there is only one worker, the waste W can be quickly and efficiently dumped into the storage space 56. In order to improve the volume reduction rate of the waste W, it is preferable to once lower the compression plate 31 to compress the waste W once a certain amount of waste W has been dumped into the storage space 56, and to secure space in which the waste W can be dumped, and repeat this process several times.

[0052] When the waste W has been completely poured into the storage space 56 and is ready for final compression, the lashing cord 57 is tucked in place as shown in FIG.

[0053] Specifically, the tack string 57 is routed so that the approximate central portion 57a ​​of the tack string 57 is positioned between the waste W and the bottom plate portion 53, one end 57b moves upward along the second side plate portion 55 on the opposite side of the support portion 20 across the storage space 56, and then is pulled out of the storage space 56, and the other end 57c moves upward along the second side plate portion 55 on the support portion 20 side, and then passes between the waste W and the compression plate 31, with the one end 57b pulled out to the pulled position.

[0054] Once the routing of the lashing string 57 is completed in this manner, the waste W is finally compressed.

[0055] Specifically, the position adjustment handle 35 is turned to lower the compression plate 31 to the compression start position, and as shown in Figure 8, a portion of the lashing string 57 is sandwiched between the compression plate 31 and the waste W. Then, the push-down lever 34 is moved up and down to further lower the compression plate 31, gradually compressing the waste W. The position of the cart 50 is kept at a predetermined position by the wheel chock 13 (movement limiting portion), i.e., a position where the compression plate 31 can enter the storage space 56 of the cart 50. Therefore, it is not necessary to align the position of the cart 50 with the position of the compression plate 31 before lowering the compression plate 31.

[0056] Here, as described above, the trolley 50 rides on the riding surface 12 (the upper surface of the first flat plate 11a) of the rail portion 11, and the load acting on the trolley 50, i.e., the load with which the compression plate 31 presses the waste W, acts on the first flat plate 11a of the rail portion 11 via the wheel portion 51.

[0057] Therefore, although a reaction force against this load is generated in the first flat plate 11a, the first flat plate 11a is part of the rail portion 11 constituting the base portion 10 and is part of the compressor 100, so the compressor 100 itself is not lifted by the load with which the compression plate 31 presses the waste W. Therefore, it is possible to apply a relatively large compressive load to the waste W, and as a result, the volume reduction rate of the waste W can be improved.

[0058] When the compression of the waste W is completed, the waste W is fastened by the fastening string 57.

[0059] The waste W is secured by the lashing string 57 by tying one end 57b and the other end 57c of the lashing string 57 together, but since the one end 57b and the other end 57c of the lashing string 57 are pulled out from near the upper end of the second side plate 55 on the opposite side of the storage space 56 from the support part 20, the worker can easily tie them together without bending or crouching. This prevents the compressed waste W from returning to its original state.

[0060] Furthermore, when tying one end 57b of the tack string 57 to the other end 57c, the compression plate 31 is pressed against the waste W, and the part of the tack string 57 on the other end 57c side is sandwiched between the compression plate 31 and the waste W. However, since the underside 31c of the compression plate 31 with which the tack string 57 comes into contact has a smooth surface without any protrusions, the part on the other end 57c side can be easily pulled out without getting caught on the compression plate 31.

[0061] Once the waste W has been secured with the lashing strings 57, the compression plate 31 is raised to its initial position by turning the position adjustment handle 35, and the cart 50 is lowered from the compressor 100. The waste W secured with the lashing strings 57 is then carried to a predetermined accumulation area while still on the cart 50. In this way, the waste W after volume reduction can also be easily removed by using the cart 50.

[0062] After going through the above-described steps, the waste W stored in the cart 50 is sufficiently reduced in volume by the compressor 100 and then carried out together with the cart 50.

[0063] According to the above embodiment, the following effects are achieved.

[0064] According to the compressor 100 having the above-described configuration, a riding surface 12 on which the wheel portion 51 of the cart 50 containing the waste W rides is provided on the base portion 10, and the load acting on the cart 50, i.e., the load with which the compression plate 31 presses the waste W, acts on the base portion 10 via the wheel portion 51.

[0065] Therefore, although a reaction force against this load is generated in the base portion 10, because the base portion 10 is part of the compressor 100, the compressor 100 itself is not lifted by the load with which the compression plate 31 presses the waste W. Therefore, it is possible to apply a relatively large compressive load to the waste W, and as a result, the volume reduction rate of the waste W can be improved.

[0066] In this way, the waste W stored in the cart 50 is subjected to volume reduction processing with a relatively large compressive load, and the volume-reduced waste W is carried out together with the cart 50, thereby enabling efficient volume reduction processing of a large amount of waste W. Furthermore, by significantly reducing the volume of the waste W, it is possible to reduce the disposal cost of the waste W and also the transportation cost of the waste W.

[0067] Furthermore, according to the compressor 100 having the above-described configuration, of the gap formed between the compression plate 31 in a position before compressing the waste W and the cart 50 riding on the riding surface 12, the gap on the support part 20 side is covered by the back plate part 40 attached to the support part 20.

[0068] By installing the back panel portion 40 in this manner, it is possible to prevent the waste W from overflowing onto the support portion 20 side when the waste W is placed into the cart 50 or when the waste W is compressed, and as a result, the volume reduction process of the waste W can be carried out efficiently.

[0069] Furthermore, in the trolley 50 configured as described above, the pair of first side plate portions 54 and the pair of second side plate portions 55 have different heights from the bottom plate portion 53, and the first height H1 of the first side plate portions 54 is set higher than the second height H2 of the second side plate portions 55. In other words, of the side plate portions 54, 55, the upper ends of the pair of first side plate portions 54 that are arranged opposite each other are positioned vertically higher than the upper end of the other side plate portion, the second side plate portion 55.

[0070] By setting the first height H1 of the first side plate portion 54 higher in this manner, it is possible to prevent the waste W from overflowing beyond the first side plate portion 54 when the waste W is loaded into the cart 50 from the second side plate portion 55, which has a lower height, or when the waste W is compressed, and as a result, the volume reduction process of the waste W can be carried out efficiently.

[0071] The following modified examples are also within the scope of the present invention, and it is possible to combine the configuration shown in the modified example with the configuration described in the above embodiment, or to combine the configurations described in the different modified examples below.

[0072] In the above embodiment, the waste W is directly put into the storage space 56 of the cart 50. Alternatively, as in the cart 150 shown in Fig. 9, a container bag 60 and a double packaging bag 62 may be placed in the storage space 56. Fig. 9 is a cross-sectional view showing a cross section of a modified cart 150, and shows a cross section corresponding to the cross section shown in Fig. 5.

[0073] The container bag 60 is a so-called flexible container bag (flexible container bag) made of a flexible material, for example, a resin fabric such as polypropylene, and has a suspender belt (not shown) that allows it to be suspended by a crane or the like. The container bag 60 is a square-bottom type, the bottom of which is approximately square like the bottom plate portion 53, and is placed inside the cart 150 with the bottom in contact with the upper surface of the bottom plate portion 53. Note that the container bag 60 is not limited to a square-bottom type, and a round-bottom type, the bottom of which is approximately circular, may also be used.

[0074] The double packaging bag 62 is a transparent bag made of plastic such as polyethylene, and is composed of an outer bag 63 and an inner bag 64 housed within the outer bag 63 and having substantially the same shape as the outer bag 63.

[0075] The outer bag 63 is installed with its bottom in contact with the bottom of the container bag 60 and its open end located near the outer lower ends of the side plates 54, 55. In other words, the outer bag 63 is folded back at the upper ends of the side plates 54, 55 and attached to the cart 150 so as to cover the outer surfaces of the side plates 54, 55. Similarly to the outer bag 63, the inner bag 64 is also folded back at the upper ends of the side plates 54, 55 and attached to the cart 150 so as to cover the outer surfaces of the side plates 54, 55.

[0076] A fastening string 57 (not shown) is attached to the inside of the inner bag 64 in the same manner as in the above embodiment.

[0077] Here, if the waste W is a sheet or tape used for protection during asbestos removal work, measures must be taken to prevent dust such as asbestos fibers generated during the asbestos removal work from leaking outside.

[0078] In such a case, the volume of the waste W is reduced using a cart 150 in which a container bag 60 and a double packaging bag 62 are placed in the accommodation space 56 as shown in FIG.

[0079] Specifically, the waste W is subjected to volume reduction processing in the same manner as in the above embodiment, and when the waste W is secured by the securing strings 57, the inner bag 64 is sealed and the outer bag 63 is also sealed. Furthermore, when the container bag 60 is sealed, the cart 150 carrying the container bag 60 becomes ready to move outside the isolated space (security zone).

[0080] Therefore, similar to the above embodiment, when the dolly 150 having the above configuration is used, it is possible to efficiently perform volume reduction processing of a large amount of waste W. Furthermore, since the waste W is stored in the container bag 60 with a hanging belt, it can be easily transported even after being lowered from the dolly 150.

[0081] In the above embodiment, the moving mechanism 32 is a mechanism that manually moves the compression plate 31 in the vertical direction. Alternatively, the moving mechanism 32 may be a mechanism that is electrically or hydraulically driven to move the compression plate 31 in the vertical direction. For example, as in the modified example shown in Fig. 10, the moving mechanism 32 of the compressor 200 may be configured to move the compression plate 31 in the vertical direction using an electric unit 71.

[0082] In the modified example shown in FIG. 10, the operation of the moving mechanism 32, i.e., the movement of the compression plate 31 in the vertical direction, is not performed manually using the push-down lever 34 or the position adjustment handle 35 as in the above embodiment, but is instead electrically driven by an electric unit 71 connected to the moving mechanism 32 via a reduction mechanism 74 and a transmission shaft 73.

[0083] As the electric motor 71, a device equipped with an electric motor capable of rotating forward and backward, for example, a commercially available electric tool such as an electric drill driver, is used. Specifically, an electric tool that generates a torque of about 10 to 20 Nm is used. Note that the electric motor 71 may be an electric motor designed specifically for the compressor 200, but in order to reduce the manufacturing cost of the compressor 200, it is preferable to use a commercially available electric tool or the like.

[0084] Although a corded (AC powered) power tool may be used as the electric part 71, in order to enable the compressor 200 to operate even in places without a power source, it is preferable that the electric part 71 be a rechargeable power tool driven by a battery 72. Even in the case of a rechargeable power tool, it is possible to work for a long time by replacing the battery 72.

[0085] The reduction mechanism 74 is a mechanism for reducing the speed of the rotation of the electric unit 71 transmitted via the transmission shaft 73 and transmitting the rotation to a pinion (not shown) of the movement mechanism 32, and includes well-known gears such as worm gears and bevel gears arranged according to a reduction ratio, etc. The reduction mechanism 74 has a self-locking function that can maintain its position in both forward and reverse rotation. It is preferable to use a ready-made product in order to reduce the manufacturing cost of the compressor 200.

[0086] The reduction mechanism 74 is attached and fixed to the moving mechanism 32, and the electric motor 71 is attached and fixed to the horizontal frame 22 of the support unit 20. A support member that stably supports the electric motor 71 in a predetermined position by receiving the reaction force generated by the forward and reverse rotation of the electric motor 71 may be provided on the horizontal frame 22 so as to surround the electric motor 71. In this case, it is preferable to provide an opening in the support member as appropriate to prevent heat generated by the electric motor 71 from being trapped inside the support member. For safety reasons, a protective cover may be provided to cover the transmission shaft 73, which is the rotating part.

[0087] An operating unit 76 for operating the motorized unit 71 to move the compression plate 31 up and down is provided on the support column 21 of the support unit 20 .

[0088] The operating unit 76 is provided with switches 76a and 76b for switching the motorized unit 71 between forward and reverse rotation, and an operating lever 76c for adjusting the output of the motorized unit 71.

[0089] The switches 76a and 76b are switches for switching between raising and lowering the compression plate 31. When the switch 76a located above is selected, the motor unit 71 rotates to raise the compression plate 31, and when the switch 76b located below is selected, the motor unit 71 rotates to lower the compression plate 31.

[0090] Considering that the operating unit 76 will be operated by a worker, it is installed below the electric unit 71 and at a position that is easy for the worker to operate, for example, at about the same height as the worker's waist, as shown in Figure 10.

[0091] In this way, in the compressor 200 shown in Figure 10, the compression plate 31 can be moved vertically as desired, just like the compressor 100 of the above embodiment, so that the volume reduction process of the waste W can be performed in the same manner as in the above embodiment.

[0092] Furthermore, the movement of the compression plate 31 in the vertical direction is performed electrically by an electric mechanism consisting of an electric unit 71 and a moving mechanism 32, which significantly reduces the workload of the worker compared to when it is performed manually using a push-down lever 34 or a position adjustment handle 35.

[0093] Furthermore, the electric mechanism made up of the electric unit 71 and the moving mechanism 32 is operated via an operating unit 76 installed at a location remote from these, so that the electric mechanism can be safely and easily operated from a location remote from the electric mechanism. Note that the operating unit 76 is not limited to being fixed to the support column 21, and may be, for example, a pendant-type operating device suspended from the support column 21 or the cross member 22.

[0094] Furthermore, in the above embodiment, the height of the compression section 30 supported by the support section 20 is fixed, but the height of the compression section 30 may be changeable, as in the modified example shown in Figures 10 and 11.

[0095] In the modified example shown in FIGS. 10 and 11, the support column 21 of the support part 20 is provided with an expandable part 24 that can change the position of the compression part 30 in the vertical direction.

[0096] The extension / contraction section 24 is a telescopic extension / contraction mechanism that can extend and contract in the vertical direction by inserting the upper support column 21a into the lower support column 21b. The upper support column 21a has a plurality of through-holes (not shown) that penetrate horizontally and are spaced apart at predetermined intervals in the vertical direction, and the length of the support column 21, i.e., the height of the compression section 30, can be changed to any height by inserting a fixing pin 21c into both the through-hole (not shown) formed in the lower support column 21b and one of the through-holes formed in the upper support column 21a.

[0097] The length of the support column 21, i.e., the height of the compression section 30, can be changed by bringing the underside of the compression plate 31 into contact with a load-receiving member 78 installed on the installation surface 1 or in a trolley (not shown), as shown in Figure 11, so that the weight of the moving mechanism 32, etc. is supported from below via the compression plate 31, and then removing the fixing pin 21c so that the upper support column 21a can be moved relative to the lower support column 21b.

[0098] In this state, when the moving mechanism 32 is operated to move the compression plate 31 downward, as shown by the dashed arrow in Figure 11, the upper support pillar 21a moves upward along with the moving mechanism 32, and the extension section 24 extends, thereby increasing the length of the support pillar 21, and as a result, the height of the compression section 30 increases.

[0099] On the other hand, when the moving mechanism 32 is operated to move the compression plate 31 upward, the upper support pillar 21a moves downward along with the moving mechanism 32, and the extension section 24 contracts, shortening the length of the support pillar 21, and as a result, the height of the compression section 30 decreases.

[0100] When the height of the compression section 30 reaches the desired height, the fixing pin 21c is inserted again, thereby completing the change in the height of the compression section 30.

[0101] By configuring the compression section 30 to be height adjustable in this manner, it is possible to lower the height of the compression section 30 and thereby reduce the overall height of the compressor 200, making it possible to easily transport the compressor within a building using a standard elevator. Note that when transported, the compression plate 31 of the compressor 200 is in the lowest position.

[0102] In addition, by increasing the height of the compression section 30 so that the waste W can be compressed by the compression plate 31 from a higher position, it is possible to efficiently reduce the volume of the waste W.

[0103] 10 and 11, if the compressor 200 is equipped with an electric unit 71, the length of the support columns 21 can be changed electrically, allowing for easy and quick adjustment. The length of the support columns 21 may also be changed manually using the push-down lever 34 or the position adjustment handle 35. The length of the support columns 21 may also be changed using a hydraulic jack or the like that can move the upper support columns 21a relative to the lower support columns 21b.

[0104] In the example shown in Figures 10 and 11, the back plate portion 40 is fixed to the lower support column 21b, but the back plate portion 40 may also be fixed to the upper support column 21a, or may be fixed to the lower support column 21b so as to be freely movable in the vertical direction.

[0105] In the above embodiment, the compressor 100 is transported by a lifting device such as a hand pallet. Alternatively, the compressor 100 may be transported manually without using a lifting device by providing casters on the base 10 that can come into contact with the installation surface 1 when the compressor 100 is tilted to a certain extent in a predetermined direction.

[0106] Furthermore, in the above embodiment, the bogie used for the compressor 100 is the dedicated bogie 50 having the above configuration, but the bogie used for the compressor 100 is not limited to this and may be, for example, a commercially available bogie. In this case, the size of the compression plate 31 is changed to match the commercially available bogie, and the size of the gap between the pair of rail portions 11 and the position of the wheel stopper 13 are adjusted. Note that the above-mentioned dedicated bogie 50 is preferably produced by modifying some of the side plate portions of a commercially available bogie.

[0107] In the above embodiment, the shape of the storage space 56 of the carriage 50 is cubic. Alternatively, the shape of the storage space 56 may be cylindrical. In this case, the compression plate 31 is disc-shaped to match the shape of the storage space 56.

[0108] Although the embodiments of the present invention have been described above, the above embodiments merely illustrate some of the application examples of the present invention, and it is not intended that the technical scope of the present invention be limited to the specific configurations of the above embodiments.
