Description

  The present invention relates to a compression packing device that compresses and packs construction by-products, a fall prevention pallet that loads a compressed body, and a long object cart that loads a long object.

Since many materials are used at construction sites and civil engineering sites, various types of garbage such as packing materials, cushioning materials, and cut off pieces are generated. Garbage must be paid to be treated as industrial waste, but it can be sold to a recycler if it is separated into valuables (hereinafter referred to as construction by-products). it can. Since the industrial waste that has been disposed of at a cost is separated and used as a construction by-product, it can be sold and profits can be obtained, so the financial merit is very large.
Construction by-products such as cardboard, paper, and film are compressed and packed into a shape that is easy to carry and can be moved by human hands, and are transported out as a compressed body. If the volume of the construction by-product is reduced and the volume is reduced, the amount of the construction by-product that can be transported at a time increases, and the transportation cost can be reduced. A compressor is used to compress and pack the construction by-products, but the compressor requires a strong force and operates with a 200V wiring plug connector. At small-scale sites, 200V wiring plug connectors cannot be secured, and compressors cannot be introduced, so construction by-products generated at these sites are compressed and packed by human hands. The compressed body packed and packed by human hands is not sufficiently compressed, and the amount of resources contained in the compressed body is reduced with respect to the transportation cost. Further, the binding is weak, and the binding is easily detached and scattered during transportation or storage. Furthermore, when another compression body is stacked on a compression body that is insufficiently compressed, the compression body that is insufficiently compressed due to the weight is crushed, which causes collapse of the load.

  The compressed construction by-products are collected on trucks that visit multiple sites. The collected construction by-products are collected at the collection point and transported to the recycling plant by type. At this time, in order to collectively handle the same type of construction by-products, the compacts are loaded on different pallets for each type. On the pallet, about 4 to 6 compressed bodies per stage are stacked and loaded in a plurality of stages of about 3 to 5, and are lifted and moved by a hand lift or a forklift and transported by truck. In order to prevent the compressed body loaded on the pallet from collapsing during transportation or storage, the compressed body is bound with a string for each stage, but this binding operation is very laborious. In addition, since trucks visit a plurality of sites to collect construction by-products, trucks may be loaded with bundled compacts collected from other sites. At this time, in order to combine the newly collected compressed body with the already-compressed compressed body, the work of unpacking the uppermost stage of the bundled compressed body, loading the newly collected compressed body, and re-binding is performed. It has been broken. Here, if the binding is weak, it will lead to load collapse during transportation and fall of the compressed body, and if the compressed body falls on the road, it will cause a traffic accident. Therefore, it is necessary to perform the binding firmly, but it takes time to bind firmly. This rebinding operation is performed on the truck bed, but if the truck is parked on the site or on the road, it may be urged to move the truck, which places a heavy burden on the workers.

There are many long construction by-products (hereinafter referred to as long objects) such as lightweight steel frames, vinyl chloride pipes, carbon steel pipes, etc., from the site of building renovation work, gas and water and sewage laying, and renovation. . Long items generated at the site are loaded and stored on a truck, and are transferred to a truck for collecting construction by-products from the truck, or collected together with the truck.
The length of a long object generated on the site is not uniform, and various lengths are generated. If a long object includes a longer object than the length of the carriage, the end of the elongated object protrudes from the carriage. The end of the long object may be cut and sharpened, and an operator may be injured by hitting a leg or the like on the sharp end of the long object protruding from the carriage.

  The present invention relates to a compression packing device that can be used even on the site where a wiring plug connector cannot be secured, a fall prevention pallet that can quickly perform loading work, and a cart for long objects that can safely load long objects. The issue is to provide.

  The compression packing apparatus of the present invention can be introduced not only at a site where a 200V wiring connector can not be secured, but also at a site such as outdoors where a 100V wiring connector or generator cannot be secured. When the compression packing apparatus of the present invention is installed on the truck bed, it is not necessary to install the compression packing apparatus at each site. The impact driver has a strong torque, and the construction by-product can be sufficiently compressed by driving the compression packing apparatus with the impact driver.

  The fall prevention pallet of the present invention does not need to bind the compression bodies with a string to prevent the collapse of the load, can quickly load the compression body onto the fall prevention pallet, and shortens the truck stop time. can do. By stacking other pallets on the pillars of the fall prevention pallet, the number of pallets that can be loaded on the truck bed is increased, and the number of types of construction by-products that are collected separately for each pallet can be increased.

  The cart for long objects of the present invention can load a long object without protruding from the cart, and there is no risk of being hit by hitting the sharp end of the object.

The compression packing apparatus of the present invention is shown in FIG.
The compression packaging device 1 of the present invention has a ball screw portion 11 that converts a rotational motion about the horizontal direction into a linear motion in the vertical direction, and a compression plate 12 that moves in the vertical direction by this linear motion, The ball screw portion 11 rotates without being connected to the wiring plug connector. The front door 13 is provided with a slit 14.
Examples of the method for rotating the ball screw portion 11 include a method using a crank handle, a morning glory handle or the like, or a method using a rechargeable screw driver, impact driver or the like. Among these, the impact driver is preferable because the torque is strong and the construction by-product can be compressed smaller.
Hereinafter, a compression packing apparatus driven by an impact driver will be described.

The ball screw portion 11 has an input shaft 111 extending in the horizontal direction and a screw shaft 112 extending in the vertical direction, and converts the rotational motion of the input shaft 111 into linear motion of the screw shaft 112. An end of the input shaft 111 can be connected to an impact driver, and is rotated by the impact driver. As a method of connecting the input shaft 111 and the impact driver, the end of the input shaft 111 is shaped so as to be able to be fitted to the socket of the impact driver. The method of providing etc. is mentioned. Using an impact driver equipped with a hexagon socket, it is preferable to rotationally move the input shaft 111 having a hexagonal hole formed on the end face, because a general-purpose product can be used and the cost is low, and the corner is difficult to lick. A compression plate 12 is provided at the lower end of the screw shaft 112. When the input shaft 111 is rotated by an impact driver, the compression plate 12 can be moved in the vertical direction.
The compression packing apparatus 1 of the present invention can be introduced not only at a site where a 200V wiring connector cannot be secured, but also at a site such as outdoors where a 100V wiring connector or generator cannot be secured. . It can also be installed on a truck bed to collect construction by-products.

The construction by-product can be compressed by accommodating the construction by-product in the accommodating portion, rotating the input shaft 111 with an impact driver, and moving the compression plate 12 downward. The housing portion includes a bottom plate, a back plate, a left side plate, a right side plate, and a top plate, a ball screw portion 11 on the top plate, and a compression plate 12 positioned below the top plate. The front surface of the housing portion has a front door 13 that can be opened and closed, and is used for charging construction by-products and taking out the compressed body. The front door 13 may be either a single opening or a double opening.
The size of the compression body is determined by the size of the housing portion. The compressed body is easy to handle when its size is in the range of width 400 to 600 mm × depth 300 to 500 mm × height 200 to 400 mm. Therefore, it is preferable that the accommodating portion has a width of 400 to 650 mm and a depth of 300 to 550 mm. The height of the accommodating part is preferably in the range of 600 to 1200 mm so that many construction by-products can be introduced at a time. In addition, it is preferable from the point of the handleability of an operator that the weight of a compression body is 30 kg or less.
An impact driver having a force (torque) for rotating the input shaft 111 of 150 N · m or more is commercially available. The compression packing device 1 of the present invention has a compression plate 12 having a small area of 400 to 650 mm in width and 300 to 550 mm in depth, and can apply a strong pressure to the compression plate 12 even with the driving force of an impact driver. Can be compressed small. When the input shaft 111 is rotated by a crank handle, a morning glory handle, a screw driver, etc., the pressure applied to the construction by-product is increased by reducing the width and depth of the accommodating portion and reducing the area of the compression plate 12. can do. Although the compression packing apparatus 1 of this invention is based also on the kind of construction by-product, it can compress the volume of a construction by-product to about 1/3-1/20.

  When the compressed construction by-product is taken out from the compression packing device 1 for packing, the compressed construction by-product tends to return to its original volume and the volume increases. Therefore, it is preferable that the construction by-product can be packed in a compressed state. Laying a string on the bottom plate of the housing part, stacking the construction by-product on this string, turning the string on the construction by-product, compressing the construction by-product with the string extending from above and below the compression body passed through the same slit 14 Packing the construction by-product in a compressed state by pulling the string extending from the slit 14 during the compression work or after compression, binding the strings extending from the same slit 14 and moving the compression plate 12 upward Can do. The slit 14 is provided on at least one of the front door, the back plate, the left side plate, and the right side plate.

  The compression packing apparatus 1 according to the present invention is used in construction sites of small and medium-sized construction and civil engineering sites where the amount of construction byproducts generated is relatively small. Therefore, the construction by-product generated at each site is made into a compressed body at each site or on a truck bed and collected by a truck that circulates a plurality of sites. In order to collectively handle the same type of construction by-products, the compacts are loaded on different pallets for each type. By loading and collecting the compressed bodies on the fall prevention pallet, it is not necessary to perform an operation of binding the compressed bodies with a string, and the compressed bodies can be loaded quickly. Moreover, the stop time of the truck which collects the compressed body can be shortened.

  FIG. 2 shows a first embodiment of the fall prevention pallet of the present invention. The fall prevention pallet 2 according to the first embodiment shown in FIG. 2 includes a pallet 21, four struts 22 erected at the four corners of the pallet, and a net 23 surrounding the struts. The pallet 21 can be a general one made of plastic, iron, aluminum, wood, cardboard or the like. Among these, plastic is preferable because it is lightweight and excellent in strength. In addition, since plastic is not easily contaminated, it is possible to reduce the mixing of foreign matters into the loaded compression body.

The struts 22 can be formed from plastic, iron, aluminum, wood, etc. Among them, a hollow pipe made of iron or aluminum or a perforated angle material is preferable because it is lightweight and excellent in strength. The pallet 21 and the support column 22 are preferably detachable. Examples of a configuration that allows the pallet 21 and the support column 22 to be detachable include providing insertion holes for inserting the support columns 22 at the four corners of the pallet 21. The insertion hole may or may not penetrate the pallet 21, but the through hole is easier to form. When the insertion hole is a through hole, it is preferable to provide a stopper 221 at the bottom of the column in order to prevent the column 22 from falling from the through hole. The column 22 and the stopper 221 can be firmly fixed by forming them with metal and welding them.
The net-like object 23 can be formed from a wire net, a net, or the like. Since the wire mesh is excellent in strength, it is difficult to be deformed even when a heavy compressed body leans against it, and the inclination of the column 22 can be prevented. It is preferable that the net-like object 23 is removable for each surface. The structure in which the mesh-like object 23 can be removed is a structure in which a hook is provided on the support 22 and the mesh-like object 23 is hooked on the hook, and when the support 22 is made of a perforated angle material, The structure etc. which are connected by a hook etc. are mentioned. In addition, if the mesh-like object 23 is a wire mesh, it is preferable that at least one surface of the wire mesh is connected to the support column 22 with a hinge and can be opened one side or both sides. If at least one side can be opened by one side or both sides, the compressed body can be loaded from this side. If the net-like object 23 is a net, tension can be applied by attaching it to the support column 22 in the stretched state, and it is possible to prevent the compressed body from falling from the fall prevention pallet 2 of the first aspect. A rubber net is preferred. Also, the three sides can be made of a metal net and the one side can be made of a rubber net. When one surface is made of a rubber net, the compression body can be easily loaded on the pallet from the surface made of a rubber net having elasticity.

  By making the pallet 21 and the struts 22 and the struts 22 and the nets detachable, the construction by-products can be removed with the pallet 21, the struts 22 and the nets 23 constituting the fall prevention pallet 2 of the first aspect removed. You can head for recovery. When the pallet 21, support 22, and reticulated material 23 are loaded apart, there is space in the truck bed so that materials can be placed on the truck bed to collect construction by-products. Carry-in and collection of construction by-products from the site can be performed on the same truck, and the cost is low.

  The fall prevention pallet 2 of the first embodiment is preferably stacked with another pallet 24 on the support column 22. By stacking other pallets 24 on the fall prevention pallet 2 of the first embodiment, the number of pallets that can be loaded on the truck bed is increased, and the number of construction by-products and materials loaded on the truck in a state of being separated into pallets is increased. be able to. On the fall prevention pallet 2 of the first embodiment, in addition to the fall prevention pallet of the first embodiment, a fall prevention pallet of the following second embodiment and a commercially available pallet can be stacked. In order to stack another pallet 24 on the column 22 of the fall prevention pallet 2 of the first embodiment, an insertion hole is provided on the lower surface of the other pallet 24, a stopper 224 is provided at both ends of the column 22, and the column The upper part is inserted into the insertion hole on the lower surface of another pallet 24. FIG. 3A shows a cross-sectional view in which a support 22 having stoppers 221 at both ends is inserted, and FIG. 3B shows a cross-sectional view in which the support 22 is inserted into insertion holes of the pallet 21 and another pallet 24. Since the weights of the other pallets 24 and the compression bodies loaded on the pallets 24 can be received by the surface of the stopper 221, damage to the pallets can be prevented.

FIG. 4 shows a second embodiment of the fall prevention pallet of the present invention. The fall prevention pallet 3 of the second embodiment shown in FIG. 4 includes a pallet 31 and a net 32 that is detachably attached to the pallet 31. The net 32 has hooks 321 connected to the corners, and the net 32 is attached to the pallet 31 by hooking the hooks 321 at the four corners of the pallet 31. Since the pallet 31 has many holes for weight reduction, the net 32 can be attached to the pallet 31 by hooking the hooks 321 into these holes. When the hook 321 cannot be hooked at an appropriate position on the pallet 31, the hooks 321 are connected to each other directly or via another member inside the claw insertion opening of the pallet 31. The net 32 is preferably a rubber net having elasticity. The fall prevention pallet 3 of the second embodiment can prevent the fall without binding the compression body only by covering the compression body loaded on the pallet 31 with the net 32 and fixing the net 32.
The number of nets 32 is not limited to one. When the fall prevention pallet 3 of the second embodiment has recovered the compressed body, and a strong tension is applied to the net 32 covering the recovered compressed body, the newly recovered compressed body on the net 32 And the newly recovered compressed body may be fixed by another net. Compared with the fall prevention pallet 2 of the first embodiment, the fall prevention pallet 3 of the second embodiment can quickly perform the loading operation of the compression body, and can shorten the stop time of the truck.

  The fall prevention pallet of the present invention preferably includes an IC chip (not shown) capable of short-range wireless communication on at least two adjacent surfaces. Two fall prevention pallets are usually loaded on the truck bed in the width direction and two or three in the length direction. When IC chips are provided on at least two adjacent surfaces of the fall prevention pallet, even if the fall prevention pallet is loaded on the truck bed, at least one IC chip is located outside, and information can be written and read. . When the fall prevention pallet is equipped with an IC chip, when collecting construction by-products around multiple sites, information such as which site and how many compressed bodies are loaded on the pallet can be recorded on the IC chip. Can be managed easily. In addition, by recording how many and how many kinds of construction by-product compressed bodies are collected before going to collection, it is possible to prevent an error in the number of compressed bodies collected on-site. The information written in the IC chip can be read from different IC chips by connecting the IC chips provided in one fall prevention pallet wirelessly or by wire and synchronizing the information.

In FIG. 5, the trolley | bogie 4 for long objects of this invention is shown. The long object bogie 4 has a bogie 41 and a rectangular parallelepiped extension frame 42 that is detachably attached to the short side of the bogie 41, and is the most in the length direction of the bogie within the surface of the extension frame. The far surface has a mesh 426.
The extension frame 42 is detachably attached to the short side of the carriage 41. Two extension frames 42 can be attached to each of the short sides of the carriage 41, for a total of two, but it is difficult to move a carriage with two extension frames attached alone, so attach only one. Is preferred. When only one extension frame 42 is attached, a plate member 43 that prevents the falling of the long object is installed on the short side where the extension frame of the carriage 41 cannot be attached. The plate member 43 prevents the end of the long object from protruding from the carriage, and can be formed of a metal plate, a wire net, a net, or the like. The plate material 43 is preferably made of metal and more preferably a lightweight wire mesh so that a long object cannot break through the plate material 43.

The cart 41 can be a commercially available one that has been conventionally used for storing and transporting long materials. For example, a multi-purpose cart type SI PAT manufactured by Marusa Co., Ltd., manufactured by Southwest Equipment Co., Ltd. Can be used. The trolley for long objects has a plurality of columns 411a, 411b, 412a, 412b so that the loaded long object does not roll off from the trolley.
In the extension frame 42, frames 421a and 421b extending in the vertical direction of the surface to be attached to the carriage 41 have annular portions 422a and 422b in the upper portion and locking portions 423a and 423b in the lower portion. The extension frame 42 can be detachably attached to the carriage 41 by locking the locking portion 423 to the lower portion of the column 411 and passing the annular portion 422 through the column 411. FIG. 6 shows how the locking portion 423 is locked to the support column 411. A top view before the locking portion 423 is locked to the column 411 is a1, a right side view is a2, a top view after locking is b1, and a right side view is b2. The locking portion 423 includes a substantially L-shaped contact portion 424 and a substantially U-shaped retaining portion 425. The extension frame 42 is configured such that after the contact portion 424 is applied to the support column 411 with the stop portion 425 facing upward (as shown in FIGS. 6a1 and a2), the stop portion 425 is rotated so that the three directions of the support column 411 are stopped. It fixes with 425 (state of FIG. 6 b1, b2). The locking portion 423 sandwiches the column 411 from three directions by the retaining portion 425, and does not come off the column 411 even if the long object cart 4 vibrates during movement. The configuration in which the extension frame 42 is detachably attached to the carriage 41 is not limited to this, and for example, a clamp can be used instead of the annular portion 422.

The height of the extension frame 42 is preferably lower than that of the support column 411. By making the height of the extension frame 42 lower than that of the support column 411, an operator can grasp the top of the support column 411 and easily move the carriage 41. Further, the length of the extension frame 42 is preferably equal to or less than the width of the carriage 41. By setting the length of the extension frame 42 to be equal to or smaller than the width of the carriage 41, the extension frame 42 can be stored on the carriage 41, and the storage space when a long object is not mounted can be narrowed. In addition, when the length of the extension frame 42 is equal to or less than the interval between adjacent columns 411a and 412a on one side of the carriage 41, the extension frame 42 is rotated 270 degrees around the column 411a so that the extension frame 42 is placed on the carriage 41. Easy to store. FIG. 7 shows a state in which the extension frame 42 is rotated 270 degrees and stored on the carriage.
It is preferable that the upper side of the surface of the extension frame 42 attached to the carriage 41 does not have a framework. Since the extension frame 42 does not have a framework on the upper side of the surface to be attached to the carriage 41, there is no framework straddling the upper surface of the carriage 41, so that it is easy to load a long article on the elongated article carriage 4.

  The net-like object 426 is attached to the surface farthest from the cart in the cart length direction of the extension frame 42. The net-like object 426 can be formed of a wire net, a net, or the like. Among these, a wire mesh that cannot be broken by a long object is preferable. Moreover, it is preferable that the mesh 426 is detachable from the extension frame 42. If the mesh 426 is detachable from the extension frame 42, it is easy to load and unload long objects from the surface from which the mesh 426 is removed. Examples of the method of making the mesh 426 detachable from the extension frame 42 include a method of connecting a hook to the framework of the extension frame 42 and hooking the mesh 426 on the hook.

  In the long object cart 4 of the present invention, the end surface of the loaded long object does not protrude from the net 426, and there is no risk that the worker may be injured by hitting a leg or the like on the sharp end of the long object. . The cart 4 for long objects of the present invention can be suitably used not only for storing, transporting and collecting long construction by-products but also for storing and transporting long materials used in the field. .
