Description

  The present invention relates to a conveyance device for a conveyed product, a method for carrying out a conveyed product from a transport container using the same, and a method for carrying a conveyed product into a transport container. The present invention relates to a transport apparatus for transported goods that can be transported safely with a low-cost and simple structure, a method for transporting a transported object from a transport container using the transport apparatus, and a method for transporting a transported object to a transport container.

Conventionally, container transportation using containers is known as a method of transporting cargo by trucks, rail cars, ships, and the like. Many types of containers can be selected depending on the use, etc., but the dry container has the highest number of possessions, is inexpensive, and is easy to secure. However, since an opening is formed only on one end surface side of a dry container, loading work (referred to as vanning) or unloading work (devanning) such as heavy cargo, long cargo, bulky cargo, etc. ) Was extremely difficult.
In addition, in special containers such as flat containers and open top containers, cargo suspended by a crane or the like from the open ceiling can be loaded into or unloaded from the container. It is more expensive than containers and is not easy to secure due to a small distribution volume.

  Therefore, in order to solve the above problem, the present applicant has proposed a transport apparatus and method capable of transporting various transported objects to a container (particularly, a dry container) via a pallet (for example, Patent Documents 1 to 3).

  For example, in Patent Document 1 and Patent Document 2 described above, a stage-side lifting and sliding means is provided on the floor surface of the stage adjacent to the opening side of the container to support the transported material loading pallet so as to be movable up and down and horizontally. In addition, a container-side lifting / sliding means is provided on the floor surface of the container so as to be able to move up and down and horizontally move the pallet to be conveyed, and the goods to be conveyed between the stage-side lifting / sliding means and the container-side lifting / sliding means. The thing which can deliver a loading pallet is disclosed. As a result, heavy cargo, long cargo, bulky cargo, etc. are efficiently transported to the container at a distribution center that handles a large quantity of various types of cargo, such as C / F / S (container freight station). be able to. As a result, container transportation such as heavy cargo, long cargo, and bulky cargo can be realized.

However, in Patent Document 1 and Patent Document 2, it is necessary to provide two transport means, that is, a stage-side lifting / sliding means and a container-side lifting / sliding means, which are relatively expensive. Furthermore, in order to transport the conveyed product pallet to an accurate transport position of the container or stage, a special large-sized transfer means (for example, a push / pull mechanism etc.) must be provided and this must be driven and controlled accurately. It was.
Here, in places where it is not necessary to frequently handle a large amount of cargo (for example, overseas cargo recipients), even if the transport efficiency is somewhat reduced, a relatively inexpensive, simple structure and safe transport The advent of a transport device that can transport the transport is desired.

In addition, for example, in Patent Document 3, a load carrying pallet is lifted from a floor surface by an air-lifting transport device operated by an operator between a container and a stage adjacent to the opening side of the container. What is conveyed is disclosed. Thereby, the some cargo (especially coiled steel materials etc.) which has a magnitude | size about about 1/4 of a container full length with respect to a container can be conveyed efficiently.
However, in the above-mentioned Patent Document 3, heavy cargo, long cargo, bulky cargo and the like having the size of the entire length of the container cannot be transported.

  Conventionally, there has been a demand for rail transportation of heavy objects such as press dies by containers. However, there is a possibility that the floor surface of the container may come off due to long-time vibration of the railway vehicle and impact at the time of connection, etc., causing damage to the cargo, and heavy rail transportation has not been realized. In particular, the above press mold usually transports a measuring instrument (also called checking / fixture) that measures the molding accuracy of the mold at the same time. It is not suitable for rail transportation because it is easily affected by

In particular, when a cargo loading pallet is carried into a dry container through one end opening in the longitudinal direction, the cargo loading pallet is required to be conveyed straight (maintaining straightness). That is, when the cargo loading pallet is not transported straight to the dry container, the following problems (1) to (3) occur.
(1) When the cargo loading pallet is loaded in a tilted state in the dry container and the cargo is unloaded, the cargo loading pallet rubs against the inner wall of the dry container (friction contact), and the cargo loading pallet is unloaded. It will be extremely difficult.
(2) When carrying multiple cargo loading pallets sequentially into a dry container by multiple loading operations, for example, carrying two cargo loading pallets equivalent to 20 feet into a 40-foot dry container twice If the first cargo loading pallet (the cargo loading pallet loaded into the back of the dry container) is loaded in a tilted state, the second cargo loading pallet {the front side of the dry container The cargo loading pallet carried into the (opening side) cannot fit into the dry container.
(3) The cargo loading pallet collides with the inner wall of the dry container, and the cargo loading pallet and the inner wall of the dry container are damaged.

1. Conveying device for transported material The transporting device for transported material according to the present invention includes a base member, a traveling means, a pallet supporting member, and an elevating / lowering operating means described below. It can be transported. This conveying apparatus can be provided with 1 type, or 2 or more types of combinations among the contact part mentioned later, a remote control part, a guided part, a connection part, an engaging part, and a connection / release part, for example.

  The “transport container” is not particularly limited in structure, size, material, and the like as long as it can store a pallet loaded with a conveyed product (hereinafter also simply referred to as a conveyed product loading pallet). This transport container usually has a rectangular floor surface, and its longitudinal direction is the transport direction of the transported object. Examples of the transport container include a dry container, a leafer container, an open top container, and a flat container. Of these, dry containers and leafer containers are preferred. This is because it is the most distributed, inexpensive and easy to secure. This dry container usually has a rectangular floor surface, and an opening is formed on one end side in the longitudinal direction. When transported by a transport device to be described later, the transport container can be placed on a chassis of a vehicle such as a truck, or can be removed from the chassis and placed on the floor.

  The “conveyed item” is not particularly limited in type, size, weight, etc. as long as it can be stored in the transport container via a pallet. Examples of the types of transported materials include molds, machine tools, automobiles, automobile parts, electrical products, concrete piles, precast concrete, fruits, and miscellaneous goods. Moreover, as this conveyed product, a plate-shaped product, a coil-shaped product, a long product, a rod-shaped product, a lump product, etc. can be mentioned, for example. Examples of the material of these products include steel materials, stainless steel materials, aluminum materials, plastic materials, glass materials, stone materials (for example, tombstones), and wood. Moreover, as a weight of a conveyed product, about 100kg-50ton is mentioned, for example. Generally, it is about 1 to 20 ton. Moreover, when this conveyed product is a coil-shaped product formed by winding a strip-shaped material or a linear material, the coil-shaped product has its axial center orthogonal to the transport direction (longitudinal direction) of the transport container. It is preferable to be accommodated in a transport container. This is because it is possible to prevent the coiled product winding body from jumping out in the transport direction during transport of the transport container.

The “pallet” is not particularly limited in its structure, size, material, and the like as long as it can load a conveyed product. For example, when the pallet is 1 alone or in combination with 2 or more, the pallet can substantially match the size of the planar shape inside the transport container. Thus, when the pallet is modularized (standardized) based on the length in the longitudinal direction of the floor surface of the transport container, fixing and releasing the pallet with respect to the transport container is minimized. be able to.
Here, “in the case of 1 alone, and in the case of 2 or more combined therewith, the one that substantially matches the size of the planar shape inside the transport container” means that the bottom surface of the pallet is rectangular. When considered, the shape and size can be approximately the same as the bottom surface of the transport container. Moreover, the bottom face shape obtained by combining two or more main pallets of various sizes and shapes can be set to a shape and size that substantially match the transport container. In this combined pallet, for example, the shape of the pallet shall be such that the long side (or short side) of the floor of the transport container is divided into two equal parts, three equal parts, four equal parts, five equal parts, etc. Can do. Similarly, a pallet with a size of 1/6, 2/6, 3/6 or the like, or a pallet with a non-equal size of 2/5, 3/5, etc. may be combined. In addition, a pallet divided into six equal parts having the size of a floor or the like that divides the long side direction into three equal parts and the short side direction into two equal parts, that is, a pallet that divides both the long side direction and the short side direction into two pallets. You may combine.

The pallet includes, for example, a pallet main body, a mounting portion provided on the pallet main body and for mounting and supporting the transported object, and a leg provided on the lower side of the pallet main body and grounded on the floor surface. A lower open space in which at least one of the lower side and the side is opened can be formed on the lower side of the pallet body. As this mounting part, for example, (1) a form having a plurality of band fixing holes provided at positions along the outline of the planar shape of a plurality of plate-like (or lump-like) transported objects having different planar shapes, (2) A form having a pair of inclined surfaces facing each other and capable of supporting the coiled conveyed product in contact with the outer peripheral surface (see FIG. 10), and (3) moving a plurality of elongated conveyed products in the longitudinal direction. A form having a support part that regulates and supports (see FIGS. 37 and 38), and (4) a form having a transport object fixing tool that is supported so as to be movable along a horizontal plane and can be positioned at a predetermined position (FIGS. 34). Here, the placement part of the pallet in the form (4) includes, for example, a plurality of lower base materials and a plurality of upper base materials provided orthogonal to the upper surfaces of these lower base materials. The side base material is provided with a base material fixing tool for fixing the upper base material movably along the longitudinal direction, and the upper base material is provided with a transported object fixing tool movably along the longitudinal direction. Can be. Thereby, it can be fixed corresponding to various outline-shaped conveyed objects (especially press mold etc.). In this case, it is preferable that the transported object fixing tool is supported on the upper base material and / or the lower base material via an elastic tool (for example, a rubber member, a spring, a buffer mechanism, or the like). Thereby, it is possible to suppress the influence of vibration, impact, etc. during transportation on the conveyed product (particularly a measuring instrument for a press mold) fixed by the conveyed product fixing tool. Examples of the fixing tool include a screw stopper, a clamp tool, and a hook tool.
In addition, the lower open space is mainly used as a space for inserting the transport device or a part thereof, for example, but a space for fixing a fixing member for fixing the transported object to the placement unit. Or can be used for any other application.
Note that “at least one side is open” does not necessarily mean that all of the directions are open, but “front”, “rear”, “right” and “left” This means that it only needs to be open in any one direction. That is, for example, the “lower open space” may be an embodiment in which only “lower” and “rear” are open.

  The pallet can further include, for example, connection / release means for connecting / releasing the pallet body and the pallet body of another pallet. Thereby, according to the kind (for example, magnitude | size, shape, etc.) of a conveyed product, the connection or non-connection of a some pallet can be selected suitably, and the highly versatile pallet corresponding to many types of conveyed products can be provided. As this connection form, the thing using screwing, fitting, engagement, connection, clamping, etc. can be mentioned, for example. The connecting / releasing means can be disposed, for example, at a corner portion of the loading surface of the pallet main body. Thereby, while being able to improve connection workability | operativity, the space efficiency of the mounting surface of a conveyed product can be improved.

  The pallet can have, for example, a pallet side guided portion that is guided by guide means described later. The pallet-side guided portion can have, for example, one type or a combination of two or more types among rotating rollers, rolling balls, guide surfaces, and the like.

  The structure, size, etc. of the “base member” are not particularly limited. This base member can have, for example, a substantially U-shaped longitudinal section. Moreover, this base member can be formed, for example, extending along the conveyance direction of the conveyed product (longitudinal direction of the transport container). In this case, it is preferable that a plurality (preferably a pair of left and right) are arranged in parallel. This is because the structure can be light and strong. In particular, the planar shape of the base member is preferably substantially the same as the planar shape of a pallet support member described later.

  As long as the “traveling means” is provided on the lower surface side of the base member and can travel on the floor surface, its structure, travel form, etc. are not particularly limited. This travel means is usually a means for reciprocating the transport device along the transport direction of the predetermined transport object (longitudinal direction of the transport container). Further, as the traveling means, for example, (1) a form having a rolling member that is rotatably supported on the lower surface side of the base member, (2) the rolling member and a drive for driving the rolling member. The form etc. which have a means (for example, air motor etc.) can be mentioned. From the viewpoint of being able to be configured more inexpensively and simply, it is preferable that the mode (1) does not include any means for driving the rolling member. In the mode (1), an external force is usually applied to the transport device and the transported material loading pallet by the handling means, the manpower, etc., and the transport device is caused to travel on the floor surface via the rolling member. . In the mode (2), for example, the conveying device can be run on the floor surface by the rolling member driven by the driving means. An external force may be applied to the loading pallet so that the conveying device travels on the floor surface. Examples of the rolling member include a rotating roller, a rolling ball, a rotating wheel, and an endless belt. Of these, a large number of rotating rollers are preferable from the viewpoint of being able to have a light-weight and high-strength structure.

The “pallet support member” is not particularly limited in its structure, support form, etc. as long as it can be moved up and down on the base member and can support the pallet from below. This pallet support member usually has a pallet support surface in contact with the lower surface side of the pallet. Moreover, this pallet support member can have a substantially U-shaped longitudinal section, for example. Moreover, this pallet support member can be formed, for example, extending along the conveyance direction of the conveyed product (longitudinal direction of the transport container). In this case, it is preferable that a plurality (preferably a pair of left and right) are arranged in parallel. This is because the structure can be light and strong. In particular, it is preferable that at least one end side of the plurality of pallet support members arranged in parallel is connected to each other via a connecting member.
Moreover, the said pallet support member can be modularized (standardized) on the basis of the length of the longitudinal direction of the floor surface of a transport container, for example. Thereby, the above-mentioned modularized pallet can be suitably supported by the pallet support member.

As long as the “elevating operation means” can elevate and lower the pallet support member, its structure, elevating form, etc. are not particularly limited. The elevating / lowering operation means lowers the pallet supporting member in the raised state while traveling by the traveling means, and places the pallet supported by the pallet supporting member on the floor to stop the traveling. It is configured. As a result, the transport of the transport device can be stopped when the transported material loading pallet contacts the floor surface. As a result, the conveyed product loading pallet, that is, the conveyed product can be easily positioned and placed at an accurate conveying position. Examples of the lifting / lowering operation means include an expansion / contraction mechanism, a jack mechanism, a link mechanism, a gear mechanism, and a cylinder mechanism.
Further, the elevating operation means includes, for example, an expansion / contraction member that is provided between the base member and the pallet support member and expands / contracts by supply / discharge of a fluid {usually gas (especially, air)}. A pipe for connecting the expansion / contraction member and the fluid supply source, and an open / close valve mechanism provided in the middle of the pipe and capable of supplying and discharging fluid to and from the expansion member can be provided. Thereby, while being able to raise / lower a heavier conveyed product, a conveyed product can be positioned in a more exact conveyance position. Here, the expansion / contraction member can be, for example, a tubular member. In addition, for example, one end side of the pipe may be connected to the expansion / contraction member, and a connection part for connecting another pipe connected to the fluid supply source may be provided on the other end side. This connection part can be arrange | positioned at the end surface side of the conveyance direction of the said base member and / or a pallet support member, for example.

Thereafter, when the wire rope 34 is wound up by the winch W, the transport device 41 is pulled toward the opening c1 side of the container C, and the transport object loading pallet Pb together with the transport device 41 is on the back side on the floor surface of the container C. To the opening side, and further on the floor surface of the stage 80 (see FIG. 42). During the travel, when the contact valve 47 of the transport device 41 contacts the stopper member 62 provided on the floor surface of the stage 80, the compressed air supplied to the expansion / contraction member 52 is exhausted to the outside and expanded. The contraction member 52 contracts, the pallet support member 45 is lowered, and the conveyed product loading pallet Pb supported by the pallet support member 45 is placed on the floor surface of the stage 80. Next, the conveyed product loading pallet Pb carried on the stage 64 is transferred to a desired position by a crane or the like.
Thereafter, the above-described operation (see FIGS. 41 and 42) is repeatedly performed to carry out the remaining conveyed product loading pallet Pb in the container C, and the series of the conveyed product carrying-out operation is completed.

(3) Carrying-in action of conveying apparatus Next, the carrying-in action of the conveyed product to the container C used for the conveying apparatus 41 having the above configuration will be described.
In this carrying-in operation, it is assumed that two independent conveyed product loading pallets Pb are stored in the container C. In this carrying-in operation, the above-described stage 80 adjacent to the opening c1 side of the container C placed on the chassis is used. In this transport operation, the transport device 41 that is not connected to the other elevating units 42c and 42d is used.

  First, the empty container C is transported to a predetermined work place adjacent to the stage 80 by the truck. The leveling mechanism 82 matches the floor height of the container C placed on the chassis with the floor height of the stage 80. Thereafter, the engaging bar 63 of the conveying device 41 is positioned at the cargo handling position b, and the engaging bar 63 and the claw portion f of the forklift F are engaged to bring the conveying device 41 to a desired position on the stage 64. Transport. At this time, the conveying device 41 is disposed such that the connecting member 46a faces the back side of the container C. Next, the crane is moved to a desired position where the conveyed product loading pallet Pb covers the conveying device 41 on the stage 80, and the conveying device 41 is placed in the lower open space Pb4 of the conveyed product loaded pallet Pb. Enter the state.

Thereafter, the wire rope 34 connected to the air hose 56 and the winch W is connected to the transport device 41. The wire rope 34 is wound around a roller tool 33 provided on the inner wall of the container C. In this state, when the push button valve 60 is pressed, compressed air is supplied to the expansion / contraction member 52, the expansion / contraction member 52 expands, and the pallet support member 45 is raised. Is lifted from the floor of container C. Thereafter, when the wire rope 34 is wound up by the winch W, the transport device 41 and the transported material loading pallet Pb are pulled to the back side of the container C (see FIG. 43). During the travel, when the contact valve 47 of the transport device 41 contacts the inner wall surface of the container C, the pallet support member 45 is lowered and the transported material loading pallet Pb supported by the pallet support member 45 is moved.

Note that, when the remaining conveyed product loading pallet Pb is loaded, the stopper member 62 is fixed to the opening c1 side of the container C of the loaded conveyed product loading pallet Pb.

(4) Effects of Second Embodiment As described above, in the transport device 41 of the second embodiment, a large number of rotating rollers 44 are rotatably supported on the lower surface side of the base member 43, and the pallet Pb is mounted on the base member 43. The pallet support member 45 that can be supported from below is supported so as to be movable up and down, and the expansion / contraction member 52 that expands and contracts by supplying and discharging compressed air is provided between the base member 43 and the pallet support member 45. It is possible to carry in and out a dry, heavy and bulky transported object (for example, a press die having a weight of about 4 to 20 t) using a simple cargo handling means such as. In addition, a contact valve 47 is provided in the middle of the pipe 53 connected to the expansion / contraction member 52 so as to contact the stopper member 62 and switch its flow path. When the contact valve 47 contacts the stopper member 62, the expansion / contraction member 52 expands and contracts. Since the compressed air supplied to the compression member 52 is exhausted to the outside and the pallet support member 45 is lowered, the conveyed product can be accurately conveyed to a predetermined conveyance position (travel stop position). . As a result, when the conveyed product is conveyed, the conveyed product loading pallet Pb falls off from the stage 64, or the conveyed product loading pallet Pb collides with the back wall of the dry container C or another conveyed product loaded pallet Pb. Damage or load collapse can be prevented.
Moreover, in the conveying apparatus 41 of the present Example 2, it can engage / disengage in the recessed part 49 formed in the longitudinal direction other end side of the other raising / lowering units 42c and 42d in the longitudinal direction one end side of the raising / lowering units 42a and 42b. Since the connecting lever 51 is provided so as to be swingable, the connection or non-connection can be appropriately selected according to the type (for example, size, shape, weight, etc.) of the conveyed product.
Further, in the transport device 41 of the second embodiment, the engagement bar 63 is provided so as to be freely displaceable between the cargo handling position b protruding from the pallet support surface 45a and the storage position a submerged from the pallet support surface 45a. The conveying device 41 can be easily lifted and transferred by the handling means such as a forklift via the engagement bar 63 at the handling position b.
Further, in the transport method of the second embodiment, since the transported object is transported to the container C using the stage 80, it is possible to efficiently transport various types of transported objects such as weight, length, and bulkiness. . Further, since the pallet Pb is modularized based on the length of the floor surface of the container C, the fixing / releasing operation of the pallet Pb with respect to the dry container C can be minimized.

The present invention is not limited to the first embodiment and the second embodiment, and can be variously modified embodiments within the scope of the present invention depending on the purpose and application. That is, in the second embodiment, the transported object is transported to the container C placed on the chassis. However, the present invention is not limited to this. For example, as shown in FIG. You may make it convey a conveyed product with respect to the container C. FIG.
In the second embodiment, the conveying device 41 is provided with the guide roller 40 at a position guided along the leg portion Pb3 provided on the left and right sides of the pallet Pb. However, the present invention is not limited to this. For example, the conveyance device 41 may be provided with a guide roller 40 ′ (shown in phantom lines in FIG. 24) at a position guided along the leg portion Pb3 provided at the center of the pallet Pb. Good. This further improves the straightness of the transport device.

  Moreover, in the said Example 2, although the leveling mechanism 82 which lifts the container C and adjusts the height level of the floor surface was illustrated, it is not limited to this, For example, the locking member locked to the corner metal fitting of a container It is good also as a leveling mechanism which lowers and pushes down a container and adjusts the height level of the floor surface. Further, the leveling mechanism 82 that uses the lower corner fitting c2 on the opening c1 side of the container C is illustrated, but the present invention is not limited to this, and for example, the upper and lower corner fittings on the opening side of the container are used. It may be. Further, it is preferable to provide a slope (not shown) on which the wheels of the chassis can ride on a position close to the stage 80, or provide a height adjusting plate (iron plate or the like) on the slope.

  In the second embodiment, the conveying device 41 is caused to travel on the floor surface or the conveying device 41 and the conveyed product loading pallet Pb are moved to a desired position by a cargo handling means such as a forklift or a winch. However, the present invention is not limited to this. For example, the operator can cause the transport device 41 to travel on the floor surface, or the transport device 41 and the transported material loading pallet Pb can be moved to a desired position. In particular, a self-propelled conveyance device can be run on the floor surface by an auxiliary manpower.

Further, in the transportation of the press mold in the second embodiment, the three-dimensional measuring device is usually transported together with the press mold B. In this case, as shown in FIG. 35, a substantially C-shaped base material 69 is fixed to the upper surface of the base material 67 with slits constituting the pallet Pb via a fixture 68, If the plate 73 for mounting and supporting the three-dimensional measuring device 71 is fixed via the anti-vibration rubber member 70, the container can be transported using the pallet Pb on which the three-dimensional measuring device 71 is loaded. Thereby, the vibration at the time of transportation is absorbed by the vibration isolating rubber member 70, and it is possible to suppress an adverse effect on the three-dimensional measuring device 71 due to the vibration. As a result, it is possible to realize rail transportation of press dies, which has been difficult in the past.
In particular, it is preferable to pack the three-dimensional measuring instrument 71 with a rust preventive sheet material 72 (for example, a material in which a vaporizable rust preventive agent is coated on a vinyl surface).

  Further, in the second embodiment, the transported article is loaded on the pallet connecting body formed by connecting two pallets (1/4 modular pallet). However, the present invention is not limited to this. The non-connection can be appropriately selected according to the size, shape, weight, etc. of the conveyed product. For example, as shown in FIG. 36, in the case of a bulky transported object corresponding to the inner volume of the container, it is possible to mount one transported object across a pallet connecting body formed by connecting four pallets. it can. In addition, as shown in FIG. 37, in the case of a transported object made of many steel materials slightly longer than the total length of the container, a support 74 is provided on a pallet connecting body formed by connecting four pallets. The conveyed product can be mounted in an inclined state via the tool 74. Further, as shown in FIG. 38, in the case of a transported object made of a large number of steel materials shorter than the total length of the container, a receiver 75 is provided on a pallet connecting body formed by connecting four pallets. Thus, the conveyed product can be mounted in a state in which it is prevented from jumping out in the longitudinal direction. In this case, it is preferable that the receiving device 75 is slidably supported by the slide rail 76. Thereby, it can respond to the long conveyance thing of various length. Further, as shown in FIG. 38, a meshing member 100 such as a square member can be interposed between the left and right side surfaces of the pallet Pb and the left and right inner wall surfaces of the container C. Thereby, the appropriate straightness of the pallet withdrawn from the container at the time of carrying out can be ensured. As described above, when using a pallet (or a pallet coupling body) having a size that substantially matches the floor of the container, the conveying units 41 are connected by connecting the elevating units 42c and 42d to the elevating units 42a and 42b. If comprised, this conveyance apparatus 41 can carry in and carry out a conveyed product loading pallet at a time with respect to a container.

In the first embodiment and the second embodiment, the opening / closing valve mechanisms 20 and 61 are provided only in the transport devices 1 and 41. However, the present invention is not limited to this, and remote control for remotely controlling various operations of the transport device. An opening / closing valve mechanism can also be provided in the control unit. For example, as shown in FIG. 46, a remote control unit 90 (shown in phantom lines in FIG. 9) is connected to the pipe 13 (or the air hose 16) via another pipe, and fluid is supplied to the remote control unit 90. An operation valve 91, a fluid discharge operation valve 92, and a valve 93 may be provided. Here, the fluid supply operation valve 91 switches the flow path by the push button operation to supply the fluid to the bulging member 12 and raise the pallet support member 5. Further, the fluid discharge operation valve 92 switches the flow path by the push button operation to discharge the fluid supplied to the bulging member 12 and lowers the pallet support member 5. Thus, (1) the push button valve 19 is operated to push the pallet support member 5 and the contact valve 7 is brought into contact with the stopper member 32 to lower the pallet support member 5; It is possible to appropriately select a mode in which the lifting operation of the pallet support member 5 is remotely operated by the remote operation unit 90 at a place away from 1 (for example, a driver's seat of a forklift). In addition, it is preferable to use the said (1) form and (2) form together from a viewpoint that safety | security can be improved more.
Further, for example, as shown in FIG. 47, the contact valve 7 and the push button valve 19 are not provided in the transport device 1, and the remote control unit 90 includes a fluid supply operation valve 91, a fluid discharge operation valve 92, and a valve. 93 may be provided.
Furthermore, in the carry-in / out operation of the first embodiment and the second embodiment, connection / disconnection of the track head (driving drive unit) to / from the chassis on which the container is placed can be selected as appropriate.

Hereinafter, the present invention will be described in detail with reference to the drawings by Example 3.
In the third embodiment, similarly to the second embodiment described above, the transport device 41 (approximately half the size of the floor surface of the container C) that does not connect the other elevating units 42c and 42d is used. Thus, two independent transported material loading pallets Pb (see FIG. 60) are transported (carrying out / carrying in) to the container C. Further, as a conveyed product loaded on the pallet Pb, a relatively heavy press die B (for example, about 10 t) is exemplified. In this transport method, a large forklift F (about 10 t class) having a size that cannot enter the container C is used. In this transport method, it is assumed that the opening c1 side of the container C mounted on the truck chassis is adjacent to the stage 98 {platform (for example, load resistance 5 t / m ² )}. Further, in this transfer method, a transfer stage 99 that can be transferred by a large forklift F is used.

(1) Unloading action and effect of transport device First, as shown in FIG. 48, the container C storing the transported material loading pallet Pb is transported to a predetermined work place adjacent to the stage 98 by the truck, and by the landing gear, The level of the container C placed on the chassis is adjusted. Then, the door of the container C is opened, and the transported material pallet Pb placed on the floor surface of the container C on the opening c1 side is transferred to a desired position outside the container C by the large forklift F. To do.

  After that, as shown in FIG. 49, the transfer stage 99 on which the transfer device 41 is mounted on the floor surface is transferred to the floor surface on the opening c1 side of the container C by the large forklift F. At this time, the floor surface of the transfer stage 99 and the floor surface of the container C are substantially at the same level. Next, a fixing band (not shown) that fixes the transfer device 41 to the transfer stage 99 is removed, and the transfer device 41 is placed on the floor surfaces of the transfer stage 99 and the container C by the operator. Is pushed into the back side of the container C, and enters the lower open space Pb4 of the conveyed product loading pallet Pb.

  Then, while connecting the air hose 56 to the joint tool 54 of the conveying apparatus 41, the other end side of the wire rope 34 with the one end side connected to the large forklift F is engaged with the annular member 48. From this state, when the fluid supply operation valve 91 (lift button) of the remote control unit 90 (see the phantom line in FIG. 9) is pressed, compressed air is supplied to the expansion / contraction member 52 and the expansion / contraction member 52 expands. The pallet support member 45 is raised, and the conveyed product loading pallet Pb is lifted from the floor surface of the container C by the rising pallet support member 45.

  Thereafter, as shown in FIG. 50, when the large forklift F travels away from the container C, the conveying device 41 is pulled through the wire rope 34, and the conveyed product loading pallet Pb is moved along with the conveying device 41 to the container C. It travels on the floor surface from the back side to the opening c1 side. When the transported material loading pallet Pb travels to the floor surface on the opening c1 side of the container C, the operator operates the contact valve 47 (or the fluid discharge valve 92 of the remote control unit 90) to expand the pallet. The compressed air supplied to the contracting member 52 is exhausted to the outside, the expanding / contracting member 52 contracts, the pallet support member 45 is lowered, and the conveyed product loading pallet Pb supported by the pallet support member 45 opens the container C. It is placed on the floor surface on the part c1 side.

  Thereafter, as shown in FIG. 51, an empty transfer stage 99 is transferred to the floor surface on the opening c1 side of the container C by a large forklift F, and the transfer device 41 is placed on the floor surface of the transfer stage 99. Pulled out. Thereafter, as shown in FIG. 52, the transported material loading pallet Pb placed on the floor surface on the opening c1 side of the container C is transferred to a desired position outside the container C by a large forklift F, and a series of The unloading work will be terminated.

  By such a carrying-out method, the container C and the large forklift F are used for the container C mounted on the truck chassis without removing the container C from the truck chassis using a large crane or the like and placing it on the floor. Thus, the pallet Pb loaded with the relatively heavy press die B can be safely carried out. As a result, it is possible to realize rail transportation using a press mold container, which has been difficult in the past, and it is possible to significantly shorten the transportation time (lead time) depending on geographical factors.

  In the above-described embodiment, as shown in FIGS. 51 and 52, the transport object loading pallet Pb is placed on the floor surface on the opening c1 side of the container C, and thereafter, the transport apparatus immediately below the transport object stacking pallet Pb. 41 is taken out of the container C and then the conveyed product loading pallet Pb is carried out of the container C. However, the present invention is not limited to this. For example, as shown in FIGS. After the transport device 41 just below Pb travels to the back side of the container C, the large-sized forklift F unloads the transported material loading pallet Pb to the outside of the container C, and then moves the transport device 41 to the outside of the container C. You may make it take out.

(2) Carrying-in operation of the transport device First, as shown in FIG. 55, an empty container C is transported to a predetermined work place adjacent to the stage 98 by a truck, and placed on the chassis by a landing gear. Adjust the level of C. And the door of this container C is open | released, and the conveyed product loading pallet Pb is transferred on the floor surface by the side of the opening part c1 of the container C with the large forklift F. FIG.

  Thereafter, as shown in FIG. 56, the transfer stage 99 on which the transfer device 41 is mounted is transferred onto the floor surface of the container C on the opening c1 side by the large forklift F. At this time, the floor surface of the transfer stage 99 and the floor surface of the container C are substantially at the same level. Next, a fixing band (not shown) that fixes the transfer device 41 to the transfer stage 99 is removed, and the operator pushes the transfer device 41 toward the back side on the floor surface of the container C. Then, it enters the lower open space Pb4 of the conveyed product loading pallet Pb.

  Then, while connecting the air hose 56 to the conveying apparatus 41, the pushing member 31 (attachment) is attached to the nail | claw part f of the large forklift F. FIG.
