Description

The invention disclosed in this application relates to a pallet system used for transporting construction materials, various articles, and other loads, and a method for transporting loads using the pallet system.

When transporting materials used in construction work to a construction site, plate-shaped or rod-shaped materials are stacked on pallets that are rectangular in plan view, tied to prevent them from collapsing, and the materials are loaded together with the pallet onto the bed of a truck. It is common practice to transport the materials, unload them in pallets at the destination construction site, and then use the materials in order from the top for construction work. However, in such a usage mode, the pallet cannot be recovered until all the materials stacked on the pallet are used or removed from the pallet, which reduces the efficiency of pallet operation. Therefore, for example, Patent Documents 1 to 3 propose a pallet operating method that makes it possible to quickly recover the pallet after unloading materials and the like to a destination.

The method of operating a pallet disclosed in Patent Document 1 is to provide a plurality of support members in a removable manner in the middle part of a bottom frame of a pallet body formed to be able to be lifted, and to stack materials on top of the support members. At the destination, multiple boards that fit within the frame of the bottom frame are placed side by side in advance, and when the material is lowered onto the boards, the supporting members are removed and the materials are placed on the boards. After that, the pallets are collected.

The pallet operating method disclosed in Patent Document 2 uses a two-tiered pallet in which a small pallet is placed on a large pallet. Materials are stacked on a small pallet with both ends protruding from both edges of the small pallet, the small pallet is fixed on a large pallet and transported, the two-tiered pallet is unloaded at the destination, and then further stacked. The small pallet is unloaded with the materials, and both ends of the materials are placed on a pair of bedding materials placed side by side with an interval slightly wider than the width of the small pallet, and then the small pallet is removed and the small pallet and large pallet are collected. That is what it is.

Among the pallet operating methods disclosed in Patent Document 3, the method described in the same document as a "second base plate recovery method" is a method in which both ends of the material ("object to be transported" in the document) are Materials are stacked on a pallet so as to protrude from both side edges of the pallet ("base plate" in the same document), and the pallet is placed and fixed on a pair of pedestal members juxtaposed on the loading platform of a vehicle for transportation. At the destination, a pair of stands are placed side by side at a distance slightly wider than the width of the pallet, and the pallet is unloaded between them, both ends of the material are placed on the rod-shaped stands, and then the pallet is extracted and collected. It is something.

Japanese Patent Application Publication No. 2000-185737 Japanese Patent Application Publication No. 2004-075266 Japanese Patent Application Publication No. 2011-126642

In all of the conventional pallet operation methods disclosed in the above patent documents, two or more supporting members ("base material" in Patent Document 1, "bedding material" in Patent Document 2) are installed in advance at the location where the pallet is unloaded. , "trestles" in Patent Document 3) need to be arranged side by side at slightly wider intervals than the pallets so as to be able to support both ends of the materials. Therefore, it takes time and effort to transport these support members from the storage location to the unloading location and to arrange them at appropriate intervals at the unloading location. There is also a risk that workers assisting in unloading may become distracted by the material being lifted above and trip over support members placed on the ground.

The invention disclosed in this application was made in view of the above-mentioned circumstances, and its purpose is to transport and unload the materials to the destination when transporting construction materials and other cargo loaded on pallets. To provide a pallet system that can be carried out efficiently and safely and that allows only pallets to be easily recovered after unloading, and a method for transporting cargo using the pallet system.

In order to achieve the above-mentioned object, the pallet system of the invention disclosed in the present application is configured by combining a pallet body and a pair of lumbers removably coupled to two opposing sides of the pallet body, The wood has a height that exceeds the thickness of the pallet main body, and the wood and the pallet main body are joined by aligning their top surfaces flush with each other and bringing their side surfaces into contact with each other, and the pallet main body The connecting means for connecting the handlebars and the handlebars is operated from the side surface of the handlebars opposite to the contact surface between the pallet body and the handlebars, and the handlebars are connected to the pallet with the handlebars in contact with the ground. The basic configuration is such that it can be separated from the main body. In addition, in this invention, the "side surface" of the lumber refers to two of the elongated surfaces parallel to the lumber axis of the lumber that intersect with the top surface and the ground surface, and It is distinguished from the "end face" (end face, end face) that is formed and intersects the side surface.

Furthermore, in the pallet system of the invention disclosed in the present application, the attachment/detachment auxiliary means for supporting the weight of the pallet body when the pallet tree is attached and detached from the pallet body while the pallet tree is in contact with the ground is provided on the pallet body. An additional configuration is adopted in which the support member is provided in the vicinity of two side surfaces intersecting the contact surface with the receptacle.

The attachment/detachment assisting means includes a support leg that is retractably attached to the pallet body and protrudes below the pallet body, and the protrusion height of the support leg is determined by the thickness of the pallet body and the handlebar. may be set to match the height difference between the two.

Furthermore, the attachment/detachment assisting means includes casters that are storably attached to the pallet body, project below the pallet body, and move the pallet body in a protruding state parallel to the axis of the lumber. The projecting height of the caster may be set to be smaller than the projecting height of the support leg.

It is more preferable that the support legs and the casters are assembled to the pallet main body so that the other is accommodated in conjunction with the protrusion of either one.

In a specific embodiment, the support leg and the caster are attached to a support shaft installed parallel to the bottom surface of the pallet body, and are held so as to be housed or protruded by rotating around the support shaft. In addition, the support leg and the caster may be configured to be connected to each other in different directions by 90 degrees about the support shaft and rotate together. Furthermore, two support legs protruding in opposite directions and one caster may be connected to form a T-shape in side view around the support shaft.

Further, the method for conveying cargo according to the invention disclosed in the present application uses a pallet system configured as described above, in which a piece of wood is connected to two opposing sides of the pallet body, and a space between at least the pieces of wood is provided. The pallet body and the lumber are transported together with the cargo placed so as to straddle the pallet, and the pallet body and the lumber are placed in a storage area for the cargo. The method is characterized in that the pallet body is uncoupled, the top surface of the pallet main body is lowered below the top surface of the receptacles, and the pallet main body is extracted from between the receptacles and recovered.

According to the pallet system configured as described above and the method of transporting cargo using the pallet system, the pallet body and the receptacle are integrally connected, and the cargo is loaded and transported on top of the pallet body, and then transported as it is. It can be unloaded at the destination. In other words, it is no longer necessary to prepare support members such as base materials, bedding materials, and frames in advance at the unloading location, which was required in the prior art. Therefore, there is no need to carry these support members from the storage area to the unloading area, or to arrange them at appropriate intervals at the unloading area. There is no longer any danger of getting distracted and tripping over the support member.

After unloading, the pallet body can be extracted from between the pieces of wood and recovered by separating the pieces of wood from the pallet body by operating from the side of the pieces of wood. In this way, it is possible to greatly improve the work efficiency related to transporting cargo and the operating efficiency of the pallet body.

Embodiments of the invention disclosed in this application will be described below with reference to the drawings. FIG. 1 shows the overall configuration of the pallet system. This pallet system 1 is constructed by combining a pallet body 2 and a pair of lumber 3 that are detachably connected to two opposing sides of the pallet body 2.

The pallet body 2 has approximately the same shape as a general pallet used for transporting and storing cargo, etc., and is provided with fork insertion openings 21 into which the claws of a forklift can be inserted, on two opposing sides in at least one direction. It is being Although the drawing shows an example of a pallet body 2 made of synthetic resin, the material of the pallet body 2 is not limited to this, and may be made of wood or metal. Further, although not shown in the drawings, a hook or the like for hanging a wire rope for lifting or a belt sling may be attached to an appropriate position on the side edge, for example.

A sleeper is a sleeper that is placed on the ground to keep the cargo and materials floating above the ground when storing them horizontally. The base material, bedding material, frame, etc. described in Patent Documents 1 to 3 mentioned above are also substantially similar members. Generally, a plurality of square timbers with a width of about ten centimeters are often arranged side by side to create a gap under the cargo, etc., into which the claws of a forklift can fit. In the present invention, a wooden square timber is illustrated in the drawings, but the material of the handle 3 applicable to this invention is not limited to wood, and may be made of synthetic resin or metal. Further, as for the cross-sectional shape of the receptacle 3, any appropriate shape that allows it to be stably placed on the ground, such as a groove shape or an H shape, may be adopted.

This pallet system 1 is based on the premise that the pallet wood 3 is used in combination with the pallet body 2, and the height of the pallet tree 3 is set to exceed the thickness of the pallet body 2 by about several tens of millimeters. There is. Hereinafter, the difference dimension will be referred to as H. In the illustrated embodiment, the thickness of the pallet body 2 is set to 120 mm, and the height of the pallet 3 is set to 150 mm, so the differential dimension H is 30 mm.

The two opposing sides of the pallet body 2 that intersect with the side surface of the pallet body 2 having the fork insertion openings 21 (if the fork insertion openings 21 are provided in two intersecting directions, the two opposing sides in either one direction) First, the top surfaces of the pallet body 2 and each other are aligned flush with each other, and the sides of the pallet are brought into contact with each other to be coupled.

For example, bolts and nuts are used to connect the pallet body 2 and the wood 3. In the illustrated embodiment, a pipe nut 31 is embedded in the width direction of the lug 3, and insert nuts 32 are embedded in two opposing sides of the pallet body 2, and long bolts 33 are screwed in from the sides of the lug 3 to secure the pallet. It is configured so that it can be fastened to the main body 2 side. According to this type of connection, even when the handlebar 3 is in contact with the ground (placed on the ground, pavement, floor, or other substantially horizontal surface of a storage area), the handlebar can be moved by operating the bolts from the side. The tree 3 and the pallet body 2 can be combined and separated.

In addition, in this pallet system 1, the height of the pallet wood 3 is greater than the thickness of the pallet body 2, so when the pallet tree 3 and the pallet body 2 are connected/separated, the pallet body is removed by the height difference H. It would be convenient if 2 could be temporarily lifted. By doing so, the heights of the pipe nut 31 and the insert nut 32 match when they are connected, and when they are separated, the weight of the pallet body 2 is not applied to the bolts 33, making it easier to insert and remove the bolts 33. For this purpose, a method such as inserting, for example, a wedge-shaped or block-shaped support (pet) between the ground and the pallet main body 2 can be adopted. However, with the method of inserting supports, it takes some effort to lift the vicinity of the four corners of the pallet body 2 at a uniform height, and it is also troublesome to remove them. Therefore, in the illustrated embodiment, the pallet main body 2 and the attachment/detachment assisting means 4 that can temporarily support the weight of the cargo placed thereon are attached to two sides of the pallet body 2 that intersect with the abutting surfaces of the pallet wood 3. (The other two opposing sides where the lumber is not joined) are always kept in two locations.

2 to 4 show configuration examples of the attachment/detachment assisting means 4. FIG. The illustrated attachment/detachment assisting means 4 is assembled by forming a notch 23 that is rectangular in plan view at the edge of the bottom plate 22 surrounding the fork insertion opening 21 of the pallet body 2. Assuming that the frontage dimension of the notch 23 opening at the edge of the bottom plate 22 is W and the depth dimension from the edge is D, the frontage dimension W of the notch 23 in the illustrated embodiment is 60 mm, and the depth dimension D is 80 mm. Further, assuming that the thickness of the bottom plate 22 of the pallet body 2 is T, the thickness T of the bottom plate 22 in the illustrated embodiment is 20 mm.

A rectangular plate 41 having a width slightly smaller than the notch 23 is rotatably attached to the inside of the notch 23 . Assuming that the short side dimension of the plate body 41 along the frontage direction of the notch portion 23 is P, the long side dimension of the plate body 41 along the depth direction of the fork insertion opening 21 is Q, and the thickness of the plate body 41 is R, the exemplary embodiment The short side dimension P of the plate body 41 in is 50 mm, the long side dimension Q is 80 mm, and the thickness R is 10 mm.

A support shaft 42 that enables rotation of the plate 41 is provided protruding parallel to the short side of the plate 41 at a position that bisects the long side dimension Q and thickness R of the plate 41. The support shaft 42 is attached to bearing members 43 embedded in both inner surfaces surrounding the notch 23 of the bottom plate 22. The bearing member 43 is set back by a dimension S from the opening edge of the notch 23 toward the inside of the pallet body 2, and is disposed at a position that bisects the thickness T of the bottom plate 22 of the pallet body 2. The retreat dimension S in the illustrated embodiment is set to 35 mm, which is slightly shorter than 1/2 of the long side dimension Q of the plate body 41.

In this way, the plate body 41 is rotatably held within the notch 23 via the support shaft 42 arranged parallel to the bottom surface of the pallet body 2. As shown in FIGS. 4A and 4C, the plate 41 is held so that when it becomes horizontal within the notch 23, the end protrudes from the opening edge of the notch 23. This allows the pallet main body 2 to be easily rotated from the outside.

When the plate body 41 is horizontal, it is stored in the notch 23, and when it is upright, one side of the plate body 41 protrudes below the bottom surface of the pallet body 2. Its protrusion height H' is [Q/2-T/2], which is 30 mm in the exemplary embodiment. In other words, the protrusion height H' when the plate body 41 is oriented vertically and protrudes downward matches the difference H between the heights of the pallet body 2 and the pallet wood 3.

In this way, approximately half of the plate body 41 protruding downward fills the height difference H between the pallet body 2 and the platform 3 in the grounded state, thereby supporting the support legs 44 that support the weight of the pallet body 2. functions as When separating the pallet body 2 placed on the ground from the pallet tree 3, if the support legs 44 are erected to temporarily support the pallet body 2, the cargo can be placed on top of the pallet body 2. Also, the bolt 33 can be easily loosened from the side of the latch 3. Note that the support legs 44 can also be used when the pallet main body 2 and the lumber 3 are placed on the ground and joined together.

Casters 5 are attached to one side of this plate 41. The caster 5 in the illustrated embodiment includes a base plate 51 attached to a plate body 41, a pair of bearing legs 52 standing upright from the base plate 51, and a rotating wheel 53 held between both bearing legs 52. The wheel 53 is mounted so that the center of the wheel 53 is positioned directly above or below the support shaft 42 that holds the plate 41 when the wheel 41 is horizontal. The protruding height U of the caster 5 when the wheel 53 is located directly below the support shaft 42 (height from the lower end of the wheel 53 to the bottom plate 22 of the pallet body 2) is the protruding height H' of the support leg 44. It is set to be smaller by about several mm (5 mm in the illustrated embodiment).

In this way, the two support legs 44 that protrude in opposite directions and one caster 5 that protrudes perpendicularly thereto are connected in a T-shape in side view around the support shaft 42, and integrally move around the support shaft 42. Rotate to. As a result, it is possible to freely switch between (a) a state in which nothing protrudes from the bottom surface of the pallet body 2, (b) a state in which the support legs 44 protrude, and (c) a state in which the casters 5 protrude. . In FIGS. 2 to 4 and 7 to 8, the states (a), (b), and (c) are shown using the same reference numerals.

Furthermore, in the illustrated embodiment, ball plungers are provided on both long sides of the plate 41 as fixing means for rotating the plate 41 by 90 degrees and positioning it in each state of (a), (b), and (c). 6 is installed. The tip of the ball plunger 6 engages with one of two hemispherical recesses 24 formed on both inner surfaces of the notch 23 to hold the plate 41 horizontally. When the plate body 41 stands upright, it engages with the upper edge or lower edge of the bottom plate 22 of the pallet body 2.

Note that in the illustrated embodiment, substantially half of one side and substantially half of the other side of the plate body 41 function as two support legs 44 that protrude in opposite directions and have the same length. It is also possible to adopt a configuration in which only one side of the plate 41 protrudes long enough to function as the support leg 44, and the other side of the plate 41 is short. Further, in the illustrated embodiment, the support legs 44 and the casters 5 are integrated, and the other is stored in conjunction with the protrusion of either one, but the support legs 44 and the casters 5 are integrated. Instead, it may be configured to be taken out and stored individually.

5 to 8 are explanatory diagrams of a method of transporting cargo using this pallet system 1. As shown in FIG. 5, when transporting the cargo L, the handles 3 are connected in advance to two opposing sides of the pallet main body 2, and the casters 5 are positioned in the fork insertion opening 21 with the casters 5 facing upward. Store means 4. In this state, the load L to be transported is placed so that both ends thereof at least straddle the space between the pieces of wood 3, preferably slightly protruding outside of the piece of wood 3. If necessary, the pallet main body 2 and the cargo L are integrally bound with a belt sling 71 or the like so that the stacked cargo L does not collapse. Then, as shown in FIG. 6, the pallet main body 2, the receptacle 3, and the cargo L are lifted together by a crane 72 or lifted by a forklift, placed on a truck 73, and transported to a destination.

At the destination, as shown in FIG. 7(a), the pallet main body 2, the receptacle 3, and the cargo L are unloaded together, placed in a storage location, and unbound by the belt slings 71 and the like. This pallet system 1 transports the cargo L with the pallet main body 2 and the pallet 3 combined, so it is necessary to transport and arrange support members such as platform and bedding material to the unloading area in advance. do not have. Further, there is no danger that a worker assisting in unloading the load will be distracted by the suspended load and trip over the support member.

Subsequently, as shown in FIG. 7(b), the plate 41 attached to the notch 23 of the fork insertion port 21 is rotated 90 degrees by hand to stand the support leg 44 on the ground. With the support legs 44 supporting the pallet body 2, the bolts 33 are loosened from the sides of the pallet 3 to release the connection between the pallet body 2 and the pallet body 2.

Once the wood 3 and the pallet main body 2 are uncoupled, the plate 41 is further rotated 90 degrees by hand to make it horizontal, and the casters 5 are directed downward, as shown in FIG. 8(c). In the state shown in FIG. 7(b), the load of the pallet body 2 is applied to the plate 41, but the plate 41 can be easily rotated by pulling down the upper side of the plate 41 toward you. When the casters 5 touch the ground instead of the support legs 44, the protrusion height U of the casters 5 is smaller than the protrusion height H' of the support legs 44, so the pallet body 2 descends by the difference, and the pallet body 2 The top surface is separated from the bottom surface of Luggage L. In this state, if the pallet main body 2 is pulled out from between the receptacles 3 using the rolling motion of the casters 5, only the pallet main body 2 can be quickly recovered. In order to make it easier to pull out the pallet body 2, it is more preferable that a handle 25 is attached to the front of the pallet body 2.

When transporting a plurality of collected pallet bodies 2 at once, the plate body 41 can be further rotated 180 degrees by hand and the casters 5 can be stored inside the pallet body 2 without making the pallet body 2 bulky. Can be stacked.

As explained above, by using this pallet system 1, construction materials and other cargo can be transported efficiently and safely, and after being unloaded to a storage location, only the pallet body 2 is transported, leaving the wood 3 behind. Can be easily recovered.
