Description

Storage container and storage body for plate-shaped objects, loading device and transport vehicle for plate-shaped objects

technical field

The present invention relates to a storage container and storage body for a plate-shaped object, a loading device and a transport vehicle for a plate-shaped object, in particular to a system for loading large glass substrates such as liquid crystal displays, plasma displays, and intermediate products in the manufacturing process. A storage container for storing large glass plates in a stacked state, a storage body to be stored, a loading device for loading the storage body, and a transport vehicle equipped with the loading device.

Background technique

In recent years, there has been an increasing demand for larger glass substrates for FPDs (Flat Panel Displays) such as glass substrates for liquid crystal displays and glass substrates for plasma displays. In particular, glass substrates called the 10th generation are more than 3000mm per side. large size. The short side of the storage container stored by stacking a plurality of these large glass plates exceeds 3000mm, so it is difficult to transport it in a horizontal state due to the width restriction of the road traffic law when the transport vehicle (such as a trailer) travels on the road. The vehicle is transported in a state inclined at a predetermined angle on the platform.

Patent Document 1 discloses a loading device (trailer for panel packaging) that tilts and loads panels. The loading device shown in FIG. 1 of Patent Document 1 includes a support stand, a pair of support frames, a panel support member, and the like. The above-mentioned support stand has pivot support portions at the front and rear portions of the trolley, and in the pivot support portions, the lower end portions of a pair of support frames whose tops are rotatably connected are pivotally supported. In addition, an intermediate hinge that is rotatable to the outside is provided at an intermediate portion in the height direction of the pair of support frames, and by this hinge, the pair of support frames stand up in a substantially mountain-shaped shape when assembled. In addition, a pair of support frames is provided with a panel support member that supports the panel in a state where the surface panel is hung close to it. That is, the loading device of Patent Document 1 places the panel close to a pair of support frames that are erected in a substantially mountain-shaped manner, and loads it.

Patent Document 2 discloses a loading device (tray for transporting flat glass) that obliquely loads glass plates. In the loading device shown in FIG. 1 of Patent Document 2, an inclined support member is provided inside a box-type trailer from which an upper member can be detached. A glass support member having an L-shaped cross section is engaged with the support member, and a plurality of glass plates are stacked on the glass support member via sandbags. In this loading device, as shown in FIG. 2 of Patent Document 2, the glass supporting member on which the glass plate is loaded is hoisted by hoisting equipment such as a crane, and accommodated in a small trailer.

In addition, the glass plates need to be fixed in the storage container so that the stacked glass plates stored in the storage container will not be chipped or broken due to movement such as vibration during transportation. Therefore, generally, the spacer paper is interposed between the glass plates in the laminated state so that the glass plates do not directly rub against each other. Further, as shown in FIG. 28 , the top plate 4 is placed on the top surface of the plate-shaped laminate 3 formed by stacking the glass plate G on the pedestal 2 of the storage container 1 in a stacked state, and the upper plate 5 of the storage container 1 Pressing unit 6 of the bench vise type supported applies a pressing force (for example, 108kg/point) to the 4 corners of the top plate 4 from above, thereby fixing the stacked glass plates without moving even during transportation in the storage container 1 (for example, Patent Document 3).

Contents of the invention

However, in the loading of the above-mentioned 10th generation large glass plate, when the loading device disclosed in Patent Document 1 is used, it is inconvenient to handle the large glass plate. When loading in the state, a large amount of work labor is required, and there is a problem that the loading operation of a large glass plate cannot be performed efficiently. Also, the support frame has an angle of 10 degrees with respect to the vertical line, and at this angle, the glass substrate violates the height restriction of the transport vehicle, so it is necessary to add an inclination of about 40 degrees.

Furthermore, since the loading device disclosed in Patent Document 2 requires lifting equipment such as a crane for lifting the glass supporting member on which the large glass plate is loaded, there is a problem that the loading equipment for the large glass plate becomes large.

Therefore, the loading devices of Patent Documents 1 and 2 have a problem of being impractical as devices for loading large glass exceeding 3000 mm in length and width.

On the other hand, in the loading device of Patent Document 1, as means for preventing damage to the panel against vibrations and shocks during transportation generated by a transportation vehicle such as a trailer, the inclination angle of the panel with respect to the support frame is set to 10°. , but it is still not sufficient as a damage prevention unit for large shocks and rolls during transportation. In addition, in the loading device of Patent Document 2, sandbags are used as the same means, but this is also insufficient as a damage prevention means against large impact and roll during transportation.

In addition, as shown in Patent Document 3, in the method of pressing and fixing the stack of glass plates from above to the storage container with a pressing unit, there is a problem that chipping and cracking of the glass plate due to vibration and impact during transportation cannot be completely eliminated. The problem. In particular, the larger the size of the glass plate, the higher the frequency of chipping and cracking during transportation. In the method of Patent Document 3, it is actually difficult to cope with the increase in size of the glass plate.

Furthermore, in order to prevent chipping and cracking of the glass plates, as described above, spacer paper is sandwiched between the glass plates, but since the glass plates are prone to static electricity, static electricity is generated on the glass plates due to vibrations during transportation, etc. There is a problem that it is difficult for the user to peel off the liner paper from the glass plate.

The problems of chipping and cracking of the glass plate due to vibration and impact during transportation, and the problem that the user is difficult to peel off the backing paper from the glass plate are not limited to the glass plate, but are applicable to all plate-shaped objects that are easily damaged and easily generate static electricity. is a common problem.

The object of the present invention is to provide a storage container and a storage body for a plate-shaped object, which can reliably prevent damage to the plate-shaped object caused by vibration and impact during transportation even if it is a large-sized plate-shaped object, and can be easily placed The liner paper was peeled off from the plate-like body.

Furthermore, the object of the present invention is to provide a loading device for a plate-shaped object and its transport vehicle, which can efficiently carry out the loading operation even for a large plate-shaped object, and can prevent the plate-shaped object from being damaged due to vibration and impact during transportation. body damage.

In order to achieve the above object, the storage container for plate-shaped objects of the present invention is used to store a plurality of plate-shaped objects in a stacked state, and is characterized in that it includes: a pedestal on which a plate formed by alternately stacking the above-mentioned plate-shaped objects and liner paper is placed. A laminated object; a stopper plate, supported on the above-mentioned pedestal, when forming the above-mentioned plate-shaped laminated object, one of the four sides of the plate-shaped laminated object is abutted; a thin sheet is covered and placed on the above-mentioned pedestal A plurality of horizontal pressing members are supported on the above-mentioned pedestal, and sandwich the above-mentioned plate-shaped laminate through the part of the backing paper hanging down on the side surface of the above-mentioned plate-shaped laminate and the sheet covering the above-mentioned plate-shaped laminate and integrally fix the above-mentioned plate-shaped laminate to the above-mentioned pedestal by means of thin sheets.

In addition, in order to achieve the above object, the plate-shaped object storage body of the present invention is configured by storing a plurality of plate-shaped objects in a stacked state in a storage container, and is characterized in that it includes: a plate-shaped stacked object placed in the above-mentioned storage container On the pedestal, it is formed by alternately stacking a rectangular plate-shaped body in a plan view and a liner paper with an area larger than the plate-shaped body; the stopper plate is supported on the above-mentioned pedestal, and is connected with the 1 side abutting; a sheet covering the plate-shaped laminate placed on the above-mentioned base; a plurality of lateral pressure members supported on the above-mentioned base with the spacer paper part hanging down on the side of the above-mentioned plate-shaped laminate The side surfaces of the above-mentioned plate-shaped laminate are sandwiched between the sheet covering the above-mentioned plate-shaped laminate, and the above-mentioned plate-shaped laminate is integrally fixed to the above-mentioned stand via the sheet.

According to the storage container of the plate-shaped object of the present invention, one side surface of the plate-shaped laminate in which the plate-shaped object and the backing paper are alternately laminated is placed on the base so as to be in contact with the stopper plate. Overlaid is a thin sheet that covers the upper surface and the 4 sides of the plate-like laminate in a tensioned state. In addition, the side surfaces of the plate-shaped laminate are sandwiched by a plurality of lateral pressure members supported on the pedestal through the liner paper portion hanging down on the side surface of the plate-shaped laminate and the sheet covering the plate-shaped laminate, and are tensioned. The sheet in this state integrally fixes the plate-like laminate to the stand. In this case, in order to firmly fix the plate-shaped laminate to the stand, it is necessary to stretch the hem of the sheet covering the plate-shaped laminate to make the sheet in a tensioned state, and then fix it with a lateral pressure member.

Thereby, a storage body is formed in which the above-mentioned plurality of plate-like objects are stored in a storage container in a stacked state.

The plate-like laminate of the storage body formed in this way is integrally fixed to the base by the sheet in the tensioned state, and therefore the tightening force by the sheet in the tensioned state is evenly applied to the plate-shaped laminate. Thereby, stress generated by vibration, impact, and the like when the storage body is transported by a transport unit such as a trailer does not locally concentrate on a part of the plate-like laminate. That is, unlike the conventional technology described in Patent Document 3, where pressing force is applied to the four corners of the top plate by the pressing unit of the bench vise type, the stress generated by the vibration during transportation does not concentrate on the plate. The four corners of the top surface of the laminate. Also, the backing paper and the sheet act as a cushion to absorb vibration during transportation.

Therefore, damage to the plate-shaped object due to vibration and impact during transportation can be reliably prevented even for a large-sized plate-shaped object.

In the plate-shaped object container of the present invention, it is preferable that the sheet is an antistatic sheet for removing static electricity. If it is an antistatic sheet, even if static electricity is generated on the plate-shaped body due to vibration during transportation, etc., it will be removed, so there is no problem that the liner paper sticks to the plate-shaped body and it is difficult for the user to peel it off.

In the plate-shaped object container of the present invention, it is preferable that the sheet has a slit hole through which the stopper plate passes when the sheet-shaped laminate is covered with the sheet. Thus, when the plate-shaped laminate is placed on the stand, even if one side surface of the plate-shaped laminate abuts against the stopper plate, the upper surface and four side surfaces of the plate-shaped laminate can be covered beautifully. Flakes cover. In addition, since the sheet covering the plate-shaped laminate can be easily brought into a tensioned state, the plate-shaped laminate can be firmly fixed to the base by the sheet.

In the container for plate-shaped objects according to the present invention, it is preferable that the lateral pressure member is detachably supported by the pedestal. Thereby, when loading a plate-shaped object on the base of a storage container, the lateral pressure member will not become an obstacle.

In order to achieve the above object, the plate-shaped body loading device of the present invention is used for loading a storage body formed by stacking and storing a plurality of plate-shaped bodies in a storage container on a transport vehicle, and is characterized in that it includes: a base; The device is arranged between the above-mentioned base and the cabin floor of the above-mentioned transportation vehicle; the elastic body is arranged between the above-mentioned base and the cabin floor of the above-mentioned transportation vehicle and is arranged at the corner of the abutment, and restrains the abutment from facing each other. The amount of rolling on the floor surface of the compartment of the transport vehicle; the inclined table, on which the above-mentioned storage body is mounted and pivotally supported on the above-mentioned base, tilts between a horizontal state and a predetermined inclined state in a state where the above-mentioned storage body is placed; The tilting unit tilts the tilting table; the lateral displacement limiting unit pushes an edge of the storage body mounted on the tilting table to a wall of the tilting table to limit the lateral deviation of the storage body relative to the tilting table; The storage body fixing unit can fix the storage body mounted on the tilt table to the tilt table and can release the fixation; the tilt state holding unit can hold the tilt table in the tilt state and can release the holding.

When loading the storage body on the loading device mounted on the transport vehicle, first, the tilting unit tilts the tilt table relative to the base to maintain a horizontal state, and the storage body is placed on the tilt table by a forklift in this state. Thereby, even if it is a large plate-shaped object, the storage body can be easily loaded on the tilt table.

Next, when the storage body placed on the tilt table is transported by the transport vehicle, the lateral deviation of the storage body with respect to the tilt table is firstly restricted by the lateral deviation limiting means. Accordingly, even if vibration or impact is applied from the transport vehicle to the tilt table, the storage body does not deviate in the lateral direction relative to the tilt table, so damage to the plate-shaped body due to lateral shift can be prevented. Thereafter, the tilting unit tilts the tilting table to change its posture to a tilted state. Next, the storage body is fixed to the tilt table by the storage body fixing unit. Next, the tilt table is held in a tilted state by the tilted state holding unit. When the posture is changed, the storage body is fixed to the tilt table by the storage body fixing means, so the storage body does not deviate from or fall off from the tilt table. Therefore, it is possible to stably change the storage body to an inclined posture.

Through the above operations, the transportation preparation of the container is completed. In the method of transportation by the loading device, the storage body is transported in an inclined state, so even a large plate-shaped body can be transported by a transport vehicle in accordance with current road traffic regulations. In addition, since the inclined table is held in an inclined state by the inclined state maintaining means, even if vibration and roll during transportation are transmitted to the base, the inclined table does not collide with the base. Therefore, it is possible to prevent damage to the plate-shaped body due to the above-mentioned collision.

In addition, when the transport vehicle transports the storage body, the vibration transmitted from the transport vehicle to the loading device is attenuated by the shock absorber disposed between the base and the floor surface of the transport vehicle, and is not directly transmitted to the loading device, so that vibration can be prevented. Damage to the plate-shaped body caused by the above-mentioned vibration. Also, the roll applied to the loading device from the transport vehicle and the lateral deviation preventing effect of the lateral deviation limiting unit are combined with each other, and a plurality of elastic members arranged between the base and the floor surface of the transport vehicle elastically deform, thereby suppressing Therefore, the storage body can be stably transported due to the small amount of rolling, thereby preventing damage to the plate-shaped body caused by rolling.

As described above, according to the loading device of the present invention, even a large plate-shaped object can be efficiently loaded, and by the function of the damage prevention unit composed of the lateral deviation limiting unit, the shock absorber, and the elastic body, it can It reliably prevents damage to the plate-like body caused by vibration and impact during operation.

In the present invention, it is preferable that the elastic body is a disc spring having a load characteristic to prevent the upper end of the inclined table from colliding with the wall surface of the transport vehicle when the base base rolls relative to the floor surface of the transport vehicle.

According to the present invention, due to the load characteristic of the disc spring, the upper end of the inclined table in the tilted state can be prevented from colliding with the wall surface of the transport vehicle when the loading device is swaying, so that damage to the plate-shaped body caused by the collision can be prevented.

The roll control unit of the present invention preferably includes: a pad; and a pad drive unit that pushes the pad toward one edge of the storage body mounted on the tilt table to push the other edge of the storage body toward the tilt table. Wall presses. The above-mentioned storage body fixing unit preferably includes: a hook that is movably installed on the above-mentioned tilt table, and engages with an engaging portion of the above-mentioned storage body loaded on the tilt table; It moves between the position where the joint is engaged and the position where the engagement is released. The above-mentioned tilting unit preferably includes: a cylinder tiltably supported on the above-mentioned base or the floor surface of the vehicle compartment of the above-mentioned transport vehicle; a rod that expands and contracts with respect to the cylinder, and the front end of the rod is connected to the above-mentioned tilt table; The rod is telescopic with respect to the cylinder. The above-mentioned inclined state maintaining unit preferably includes: a pin driving part having a pin that is fixed to the above-mentioned base and expands and contracts; Snap holes.

According to the lateral displacement restricting unit of the present invention, the pad driver pushes the pad against one edge of the container mounted on the tilt table, and presses the other edge of the container against the wall of the tilt table. Thereby, lateral displacement of the storage body with respect to the tilt table can be easily prevented. In addition, when taking out the storage body from the tilt table, the pad may be retracted and moved from the other edge portion of the storage body by the pad drive unit.

According to the storage body fixing unit of the present invention, the hook is engaged with the engaging portion of the storage body by the hook drive unit provided on the tilt table. Thereby, the storage body can be easily fixed to an inclination table. In addition, when taking out the storage body from the tilt table, it is only necessary to move the hook from the engaged position with respect to the above-mentioned engaging part to the disengaged position by the hook driving part.

According to the tilting unit of the present invention, the tilt table can be easily brought into a tilted state by extending the rod relative to the cylinder by the rod drive unit, and the tilt table can be easily brought into a horizontal state by contracting the rod.

According to the tilted state holding means of the present invention, the tilt table can be easily held in the tilted state only by the pin driving part extending the pin and engaging the pin with the hole of the engaging part. In addition, when it is desired to change the attitude of the tilt table to a horizontal state, it is only necessary to retract the pin from the hole of the engaging portion by contracting the pin by the pin drive portion.

By making the pad driving part of the lateral deviation control unit of the present invention, the hook driving part of the storage body fixing unit, the rod driving part of the tilting unit, and the pin driving part of the tilting state maintaining unit respectively electric tools such as power cylinders, safety, The loading operation of the storage body on the inclined table and the carrying out operation on the inclined table are performed smoothly.

According to the transportation vehicle of the present invention, in order to achieve the above object, it is characterized in that a plurality of the plate-shaped object loading devices described in the technical solution 1, 2 or 3 use the axial direction of the shaft supporting the above-mentioned inclined table as the traveling direction. It is connected to and mounted on the transportation vehicle via a connection member.

The delivery vehicle of the present invention is a vehicle such as a trailer, a trailer of a tractor, or a trailer mounted on a trailer. Furthermore, in the delivery vehicle of the present invention, since the plurality of loading devices are mounted on the vehicle floor in a state connected via the connecting member, the plurality of loading devices are equivalent to being mounted on the vehicle floor as one device. Thus, the loads of the plurality of loading devices are evenly applied to the floor surface of the vehicle compartment. On the other hand, when a plurality of loading devices are independently mounted on the vehicle floor surface without being connected by a connecting member, an unbalanced load is applied to the vehicle floor surface, so that the vehicle floor surface may be deformed into a wave shape.

On the other hand, as a delivery vehicle, there is known a wing-type trailer provided with a pair of wings that are opened and closed in a pop-up manner on the side and roof portions of the delivery vehicle centered on a hinge attached to a center beam of the roof of the delivery vehicle. In this trailer, the above-mentioned center beam is also deformed into a wave shape due to the above-mentioned deformation of the floor surface of the vehicle compartment, so there is a disadvantage that the wings cannot be opened and closed smoothly.

In contrast, in the present invention, as described above, a plurality of loading devices are connected with the connecting member and mounted on the floor of the vehicle as a single device, so the load is evenly applied to the floor of the vehicle, and the floor of the vehicle is evenly displaced. The central beam is not deformed, so that the wings can be opened and closed smoothly.

In order to achieve the above object, the conveying method of the plate-shaped object of the present invention is characterized in that it includes: a horizontal holding step of the plate-shaped object, holding a plate-shaped laminate formed by stacking a plurality of plate-shaped objects with at least one side of 2800 mm or more. Tilting of the loading device on the inclined table in a horizontal state; the loading process of the plate-shaped object, keeping the inclined table holding the above-mentioned plate-shaped object in a horizontal state, transporting and loading the above-mentioned loading device on the transport vehicle; the inclined holding process of the plate-shaped object , on the above-mentioned transport vehicle, the above-mentioned inclined table is tilted to hold the above-mentioned plate-shaped laminated object in the above-mentioned loading device in an inclined state; the conveying process of the plate-shaped object is carried by the above-mentioned transport vehicle while maintaining the inclined state of the above-mentioned plate-shaped laminated object to the destination.

According to the conveying method of the plate-shaped object of the present invention, when the plate-shaped laminate obtained by stacking the plate-shaped objects is loaded on the transport vehicle, the plate-shaped laminate is held and placed on the inclined table in the horizontal state of the loading device, Therefore, even a large plate-shaped object can be efficiently loaded onto a transport vehicle. In addition, when the plate-shaped laminate is transported to the destination, the inclined table is tilted to keep the plate-shaped laminate in an inclined state, so even a large plate-shaped object wider than the transport vehicle can be accommodated in the transport vehicle. It can prevent damage to the plate-shaped body caused by vibration and impact during transportation.

In addition, it is preferable to use the loading device described in any one of claims 6 to 9 as the loading device used in the method of conveying the plate-shaped object of the present invention.

detailed description

Preferred embodiments of a storage container and a storage body for a plate-shaped object, a loading device for a plate-shaped object, and a transport vehicle according to the present invention will be described below with reference to the drawings.

(container of plate-shaped body)

The storage body of the plate-shaped object of the present invention is constituted as follows: on the pedestal of the storage container of the present invention, a plurality of, for example, 1 to 180 rectangular plate-shaped objects are horizontally sandwiched between the plate-shaped objects with a size ratio plate A large rectangular liner paper is laminated, a sheet is covered on the plate-shaped laminate, and it is fixed integrally with the pedestal.

In the embodiment of the present invention, as a plate-shaped body, the following example is used for description: that is, a glass plate G for FPD, especially a liquid crystal display, at least one side of which is 2800 (mm) or more, for example, the vertical and horizontal dimensions exceed about 3000 ( mm) size mother glass substrate, and the plate thickness is 1mm or less. In addition, the size of the glass plate G is not limited to this, but the storage body of the plate-shaped object of this invention, and the loading apparatus of the plate-shaped object mentioned later are suitable for this large glass plate G.

1 to 4 show the steps up to forming the container for the plate-shaped object according to the present invention.

As shown in the first step of FIG. 1 , at first, on the pedestal 12 of the storage container 11 , a rectangular glass plate G in plan view and a rectangular liner paper 13 with a larger area than the glass plate G are aligned with the pedestal 12 on the pedestal 12 . Two positioning members (stopper plates) 14 vertically erected on each side are alternately stacked in contact with each other. Thereby, the plate-like laminate 15 placed on the base 12 is formed. In this case, since the backing paper 13 is larger in area than the glass plate G, the peripheral part of the backing paper 13 hangs down to the side surface of the plate-like laminate 15 .

The backing paper 13 has, for example, a rough surface with a smoothness of 18 seconds or less (JIS P8119, 1976). Select paper with a small contact area to avoid the transfer of the resin component of the backing paper 13 to the glass plate G and produce paper texture, burn marks, stains, etc. on the glass surface. Furthermore, the resin component of the backing paper 13 is 0.05 mass % or less (JISP8205, 1976). A paper quality that does not adversely affect the quality of the glass plate G itself due to the composite effect with the roughness of the paper surface described above is selected.

Further, the storage container 11 is mainly composed of a base 12 , a positioning member 14 , a lateral pressing member 16 and a sheet 17 which will be described later.

The pedestal 12 is configured in a frame shape by assembling a plurality of frame materials 20 , 20 . . . . The frame material 20 is made of aluminum alloy, stainless steel, SS steel, or SGHC steel, for example. The pedestal 12 is constituted by manufacturing two pieces of these rectangular tube-shaped frame materials 20 , 20 .

At least two openings 22 , 22 (see FIG. 1 ) into which a pair of forks 212 of a forklift 210 (see FIG. 9 ) are inserted are provided on one side of the pedestal 12 . A mounting plate 18 is fixed to the pedestal 12 , and a covering material such as resin is provided on the surface of the mounting plate 18 .

The positioning member 14 is arranged on the bottom side of the storage body 10 when loaded on the loading device 30 described later among the four side surfaces of the pedestal 12 , and is fixed to the pedestal 12 by bolts 19 so that it cannot be easily attached or detached. Furthermore, a notch 14A is formed in the lower portion of the positioning member 14 so as not to block the opening 22 of the pedestal 12 into which the fork 212 is inserted.

Next, as shown in the second step of FIG. 2 , one sheet 17 is covered so as to cover the upper surface and four side surfaces of the plate-like laminate 15 placed on the base 12 . Among the sheet parts 17A hanging down from the four sides of the plate-like laminate 15, on the part located on the side of the positioning member 14, as shown in FIG. A through slit hole 23 . In addition, around the slit hole 23, the reinforcing sheet 24 is in contact with and reinforced so that the slit hole 23 does not break. As a result, when the sheet 17 is covered after the sheet 17 is stacked on the base 12 while the sheet 15 is in contact with the positioning member 14 , the four sides of the sheet 15 can be beautifully covered.

The sheet 17 used may be a general resin sheet, and is more preferably an antistatic sheet. If it is an antistatic sheet, when the container 10 is transported by a transport unit such as a trailer having a loading device 30 described later, even if static electricity is generated on the glass plate G due to vibration during transport, it can be removed. Therefore, the problem that it is difficult for the user to peel the backing paper 13 from the glass plate G is alleviated. A commercially available antistatic sheet can be used, for example, Achilles Seiden F (thickness: 0.1 to 0.5 mm) manufactured by Achilles Co., Ltd. can be used. In addition, any sheet can be used as long as it has an antistatic effect equivalent to that of Achilles Seiden F manufactured by Achilles Corporation.

Next, as shown in the third step of FIG. 4 , the hanging sheet portion 17A of the sheet 17 covered on the plate-like laminate 15 is stretched toward the side of the pedestal 12. The pressing member 16 pinches the side surfaces of the plate-shaped laminate 15 via the backing paper 13 and the sheet 17 . As a result, the plate-shaped laminate 15 is integrally fixed to the base 12 by the thin sheet 17 in a tensioned state. In this case, the lateral pressure members 16 disposed facing each other sandwich the side surfaces of the plate-like laminate 15 by the lateral pressure members 16 . On the other hand, the lateral pressure member 16 arranged to face the positioning member 14 sandwiches the side surface of the plate-like laminate 15 between the positioning member 14 and the positioning member 14 .

Thereby, the storage body 10 which accommodated the several glass plate G in the storage container 11 in the laminated state is formed.

FIG. 5 is a cross-sectional view of a side surface of a plate-like laminate 15 sandwiched between a backing paper 13 and a sheet 17 by the lateral pressure member 16 shown in FIG. 6 . The liner paper portion 13A and the sheet portion 17A hanging down to the side of the plate-like laminate 15 are pushed toward the side of the plate-like laminate 15 . Therefore, the overlapped portion of the hanging backing paper portion 13A is pressed by the lateral pressing member 16 via the hanging sheet member 17A. In this case, it is further preferable that the hanging thin piece portion 17A hangs down to the side surface of the mounting plate 18 , and the thin piece portion 17A is sandwiched between the lateral pressure member 16 and the side surface of the mounting plate 18 . Thus, the sheet 17 and the lateral pressing member 16 are not in direct contact with the side surfaces of the plate-shaped laminate 15, and the glass plate G can be protected by the flexibility of the backing paper 13, while reliably pressing the four sides of the plate-shaped laminate 15, side of the mounting plate 18 .

In FIG. 4 , among the three side surfaces other than the side of the plate-shaped laminate 15 having the positioning member 14, two lateral pressure members 16 are arranged on the side facing the positioning member 14, and three lateral pressure members 16 are arranged on the left and right sides. , but not limited to this number.

5 and 6, the lateral pressure member 16 having a horizontal horizontal plate 16B at the front end is shown, but as shown in FIG. Pressure part 16. In the present invention, since the sheet 17 presses and fixes the plate-shaped laminate 15 toward the base 12 , the horizontal plate 16B of the horizontal pressing member 16 does not need to press the upper surface of the plate-shaped laminate 15 . Furthermore, it is preferable to separate the upper surface of the plate-like laminate 15 from the upper surface of the horizontal plate 16B, and the horizontal plate 16B does not press the upper surface of the plate-like laminate 15 . Furthermore, it is preferable to stick and install a buffer member 21 such as rubber on the side of the plate-like laminate of the lateral pressure member 16 .

The lateral pressure member 16 is preferably detachably attached to the mounting plate 18 so as not to become an obstacle when the glass plate G is mounted on the base 12 .

As shown in FIGS. 6 and 7 , the loading and unloading mechanism inserts butterfly bolts 25 into the through holes 16D formed on the bottom plate 16C of the lateral pressure member 16 in contact with the mounting plate 18 and the through holes 18A formed on the mounting plate 18. . Further, a washer 26 , a weld nut 27 , and a wing nut 28 are screwed in order from the side of the mounting plate 18 to the front end of the wing bolt 25 . On the other hand, between the head portion 25A of the butterfly bolt 25 and the mounting plate 18 , three disc springs 29 are inserted through a washer 31 . Thus, when the butterfly bolt 25 is rotated in the tightening direction, the wing nut 28 is close to the side of the mounting plate 18, so the mounting plate 18 is clamped by the bottom plate 16C and the welding nut 27, and the three disc springs 29 are elastically deformation, a force is applied in a direction in which the head portion 25A of the butterfly bolt 25 and the mounting plate 18 are separated. Thereby, even if the lateral pressure member 16 is detachable, it is possible to avoid insufficient fixation to the mounting plate 18 due to rotation of the butterfly bolt 25 due to vibration or the like during transportation of the storage body 10 .

The container 10 of the plate-shaped object of this invention comprised as mentioned above can exhibit the following effects.

(1) Since the plate-shaped laminate 15 is integrally fixed to the base 12 of the storage container 11 by the tensioned sheet 17 , the fastening force by the tensioned sheet 17 is evenly applied to the plate-shaped laminate 15 . Thereby, the stress generated by the vibration and impact when the storage body 10 is transported by a transport unit such as a trailer does not locally concentrate on a part of the plate-like laminate 15 .

(2) Even if the plate-like laminate 15 moves up and down due to vibration etc. during transport of the container 10 by a transport unit such as a trailer, the liner 13A and the covering paper part 13A hanging down around the sides of the plate-like laminate 15 The tensioned sheet 17 of the sheet laminate 15 is held between the sheet laminate 15 and the lateral pressure member 16, and the sheet laminate 15 is integrally fixed to the stand 12 via the backing paper 13 and the sheet 17. Up and down movement of the plate-like laminate 15 can be suppressed.

(3) In addition, when the plate-shaped laminate 15 is about to move laterally due to vibration during transportation, the plate-shaped laminate 15 is integrally fixed to the base 12 via the backing paper 13 and the sheet 17, so that the plate-shaped laminate 15 can be suppressed. Lateral movement of the stack 15 . Also, the hanging paper part 13A and the sheet part 17A are held between the plate-shaped laminate 15 and the lateral pressing member 16 so that the liner paper 13 and the sheet 17 act against the lateral direction of the plate-shaped laminate 15. Buffering for movement.

(4) In addition, by using an antistatic sheet as the sheet 17, even if static electricity is generated on the glass plate G due to vibration during transportation, etc., it can be removed. Problems that are difficult for users to peel off.

Therefore, even for a large glass plate G, the plate-like container 10 of the present invention can prevent damage to the glass plate G due to vibration and impact during transportation, and the user can easily remove the liner paper 13 from the glass plate G. Plate G peeled off.

Actually, the storage body for the plate-shaped object of the present invention is formed using a glass plate G having a mother glass substrate having a length and width of more than about 3000 (mm) and a plate thickness of 1 mm or less, and a trailer equipped with a loading device described below is used. 350 conveyances were performed, but none of the glass plates G was broken.

Moreover, when a plate-shaped laminated object is fixed to a storage container by the pressing means of the bench vise system shown in FIG. 28, the breakage frequency of the glass plate G is high.

Then, as shown in FIG. 8, the container 10 of the plate-shaped body formed as mentioned above is piled up in a warehouse. Here, the mechanism for stacking the container 10 will be described.

As shown in FIG. 1 , concave fitting holes 33 are respectively formed at four corners of the upper surface and the lower surface of the pedestal 12 , and pillars 41 are erected in the four fitting holes 33 . The strut 41 is composed of a large-diameter body portion 41A and a guide portion 41B on the tip side having a smaller diameter than the body portion 41A. The protruding end of the guide portion 41B is formed in a quadrangular pyramid shape or a conical shape. On the other hand, the upper surface side of the fitting hole 33 of the pedestal 12 has a shape that can accommodate the main body portion 41A, and the bottom surface side is formed in a shape that fits into the guide portion 41B. As a result, four pillars 41 stand up in the fitting holes 33 at the four corners of the upper surface of the pedestal 12, and the guide portions 41B of the four pillars 41 are fitted on the lower surface of the pedestal 12 of the second-stage container 10. Formed fitting hole 33 . As a result, the container 10 is stacked in two stages, so the number of stacked stages is increased in the same procedure. FIG. 8 is a diagram in which three storage bodies 10 are stacked.

In addition, shock-absorbing pads 45 such as rubber are pasted on the interface between the main body portion 41A and the guide portion 41B to reduce the impact transmitted from the upper container 10 to the lower container 10 when the containers 10 are stacked in multiple stages. In this way, by stacking the storage bodies 10 in a horizontal state, the storage space of the warehouse can be effectively used compared to the case where the storage bodies 10 are vertically placed.

When using a forklift 210 to transport the storage body 10 from the warehouse to a transport unit such as a trailer, as shown in FIG. trailer. Then, on the loading device 30 mounted on the trailer, the storage body 10 is loaded in an inclined state with the positioning member 14 as the bottom surface.

Next, the loading device 30 of the plate-shaped object of the present invention will be described in detail. In addition, the container 10 for the plate-shaped object loaded on the loading device 30 is not limited to the above-mentioned container for the plate-shaped object of the present invention.

(loading device for plate-shaped objects)

FIG. 11 shows a left side view of a trailer (transportation vehicle) 200 on which the loading device 30 is mounted. And, Fig. 12 shows the front view of the loading device 30 in which the storage body 10 is held in a horizontal state on the loading device 30 loaded on the trailer 200, and Fig. 13 shows that the storage body 10 is tilted on the loading device 30 loaded on the trailer 200 Front view of the state-maintained loading device 30 . In addition, the container 10 is placed on the inclined table 34 by the forklift 210 shown in FIG. 14 in the horizontal state shown in FIG. 12 , and is carried out from the inclined table 34 .

As shown in FIG. 11 , three loading devices 30 are mounted on the vehicle floor surface 202 of the trailer 200 in a state of being arranged in parallel at predetermined intervals. Specifically, the three loading devices 30, 30... are arranged so that the axial direction of the shaft 36 in FIGS. The vehicles are mounted in a row on the vehicle floor surface 202 so that the traveling directions are the same. Furthermore, the three loading devices 30 , 30 . . . are connected via steel materials (connection members) 204 , 204 arranged vertically between the adjacent loading devices 30 , 30 , and are mounted on the vehicle compartment floor surface 202 . In addition, in FIG. 11 , three loading devices 30 , 30 . . . are illustrated, but the number of loading devices may be two or one. In addition, in FIG. 11 , the trailer 200 pulled by a truck is illustrated, but the transport vehicle on which the loading device 30 is mounted may be a loading stand of the trailer or a trailer mounted on the trailer.

In the trailer 200, the three loading devices 30, 30... are mounted on the vehicle floor surface 202 in a state connected via the steel material 204, so the three loading devices 30, 30... are equivalent to being mounted on the vehicle floor as one weight device. Surface 202. Thus, the loads of the three loading devices 30 , 30 , . . . are evenly applied to the vehicle compartment floor surface 202 . On the other hand, when a plurality of loading devices 30 , 30 . . . are independently mounted on the vehicle floor surface 202 without being connected by the steel material 204 , the vehicle floor surface 202 may be deformed into a wave shape due to an unbalanced load applied to the vehicle floor surface 202 .

The trailer 200 of the embodiment, as shown in FIGS. 12 and 13 , is a pair of wings 208 and 208 that can be opened and closed by popping up around a hinge 207 attached to a central beam 206 of the roof of the trailer 200 as the center of the side and roof portions. wing trailer. In this trailer 200, since the central beam 206 is also deformed into a wave shape due to the above-mentioned deformation of the cabin floor surface 202, there is a problem that the wings 208, 208 cannot be opened and closed smoothly.

On the other hand, in the trailer 200 of the embodiment, the three loading devices 30, 30, ... are connected with the steel material 204 and mounted on the vehicle floor surface 202 as one weight device, so that the load is evenly applied to the vehicle floor surface 202. Since the cabin floor surface 202 is displaced downward on average, the central beam 206 does not deform into a wavy shape, and therefore there is an advantage that the wings 208, 208 can be opened and closed smoothly.

Next, the loading device 30 will be described.

As shown in FIGS. 12 and 13 , the loading device 30 is mainly composed of a base 32 and an inclined table 34 . The base 32 and the tilt table 34 are made of, for example, iron or stainless steel.

As shown in FIG. 13, the base 32 is provided with the disc spring mechanism (elastic body) of FIG. ) 40 is mounted on the pedestal plate 214 provided at the center of the cabin floor surface 202 of the trailer 200 . Furthermore, by providing the pedestal 214 at the center of the pedestal 202, the height of the pedestal 202 on both sides of the pedestal 214 is lowered by the height of the pedestal 214, and by using this difference in height, as shown in FIG. The lower portion of the tilt table 34 enters into the low compartment floor surface 202 . As a result, even a large container 10 can be loaded obliquely on the trailer 200 whose vehicle width and vehicle height are limited by traffic regulations.

On the upper part of the base 32, as shown in FIG. 16, bearings 42, 42 which pivotally support the tilting table 34 freely and tiltably are provided. Bearings 42 are fixed by bolts at two places on both sides of the upper portion of the base 32 , and the tilt table 34 is rotatably supported by the bearings 42 , 42 via the shaft 36 . Thereby, the tilt table 34 tilts with respect to the base 32 between the inclined posture shown in FIG. 16 and the horizontal posture shown in FIG. 17 . In addition, the shaft 36 is held by the substantially central portion of the lower portion of the tilt table 34 via bearings 37 , 37 .

As shown in FIG. 13 , a receiving plate 35 is provided on the tilting table 34 , and the receiving plate 35 receives the lower end surface of the storage body 10 loaded on the tilting table 34 when the tilting table 34 is in an inclined posture. Furthermore, on the lateral edge portion of the tilt table 34, as shown in FIG. As will be described below, when one edge portion 10B of the storage body 10 loaded on the tilt table 34 is pushed by the lateral deviation limiting device (lateral deviation limiting unit) 46 shown in FIGS. 18 and 19 , the storage body 10 The other edge portion 10A is pushed by the restricting plate 39, and the lateral deviation of the storage body 10 relative to the tilt table 34 is reliably prevented. In addition, the lateral edge portion of the tilt table 34 is an edge portion in a direction perpendicular to the traveling direction of the trailer 200 shown in FIG. 11 .

The loading device 30 of the embodiment has, in addition to the above-mentioned base 32, tilting table 34, vibration isolator 38, and disc spring 40, a screw jack (tilting unit) 44 for tilting the tilting table 34; as shown in FIGS. 18 and 19 . The lateral deviation limiting device 46; the storage body fixing device (storage body fixing unit) 48 shown in FIG. 20 and FIG.

FIG. 24 is a schematic plan view of the base 32 showing the arrangement positions of the vibration isolator 38 and the disc spring mechanism 40 with respect to the base 32 .

As shown in the figure, with respect to the base 32 which is rectangular in plan view, the vibration isolators 38 are respectively arranged at the corners of the base 32, and four are arranged at equal intervals in the long side direction, and two are arranged in the short side direction. . Furthermore, one disc spring mechanism 40 is disposed on each of brackets 52 extending from the corners of the base 32 in the longitudinal direction of the base 32 .

As shown in the side view of FIG. 25 and the longitudinal sectional view of FIG. 26 , the vibration isolator 38 is composed of three shock absorbers 54 , 54 . . .

The damper 54 is a ring-shaped rubber member that exerts a damping effect by being compressed in the direction of the central axis of the damper 54 (direction O in FIG. 25 ). These dampers 54, 54... are inserted through a shaft 60 erected on the bottom plate 56, and are stacked in the vertical direction. The bottom plate 56 is formed in a rectangular shape as shown in FIG. 15 , and its corners are respectively fixed to the base plate 214 by bolts 62 .

As shown in FIG. 26 , the cover 58 is a substantially cylindrical object whose upper part is closed and the lower part is open, and the upper part covers the damper 54 inserted through the shaft 60 . In addition, a pair of brackets 64 , 64 extend in the horizontal direction at symmetrical positions centered on the central axis of the cover 58 (the same direction as the O direction in FIG. 25 ) on the lower outer peripheral portion of the cover 58 . Bolts 66 erected on the bottom plate 56 are inserted through holes (not shown) formed in these brackets 64 , and by fastening nuts 68 to the bolts 66 , the cover 58 passes through the shock absorbers 54 , 54 . . . ...fixed to the bottom plate 56 . Furthermore, the cover 58 is fixed to the lower portion of the base 32 with bolts 70 .

According to this configuration, the three dampers 54, 54, ... are sandwiched between the bottom plate 56 and the cover 58, and the three dampers 54, 54, ... are compressed and fastened to the nut 68 in the central axis direction of the damper 54. , so that the attenuation effect produced by the shock absorbers 54, 54, . . . is brought into play in the initial stage. Therefore, by the attenuation effect of these vibration isolators 38, 38..., the vibration transmitted from the cabin floor surface 202 of the trailer 200 to the base 32 of the loading device 30 is attenuated, thus preventing the glass plate G caused by the vibration from vibrating. damage.

On the other hand, as shown in FIGS. 15 and 27 , the disc spring mechanism 40 has disc springs (spring force: 10 ton) 72 , 72 , 72 arranged in parallel in three stages above and below via a bracket 52 . In addition to the disc springs 72, 72, 72, the disc spring mechanism 40 is composed of a threaded shaft 74, washers 76, 76..., a sleeve 78, nuts 80, 80.... The disc springs 72, 72, 72 can be arranged in series. Whether to arrange in-line or in parallel depends on the reaction force of the necessary spring.

As shown in FIG. 15 , the threaded shaft 74 is erected on a rectangular support plate 82 . The corners of the bracket 82 are fixed to the base plate 214 by bolts 84 .

As shown in FIG. 27 , on the threaded shaft 74 , nuts 80 , 80 on the lower side are screwed through the bracket 52 , and on the upper part of the nut 80 , the disc springs 72 , 72 , 72 on the lower side are inserted through the washer 76 . . Further, a sleeve 78 is inserted through the upper portion of the disk spring 72 via a washer 76 . In this state, the threaded shaft 74 is inserted into the hole 53 formed in the bracket 52 . And, through the bracket 52, the three disc springs 72, 72, 72 on the upper side are inserted into the threaded shaft 74 through the washer 76, and the nuts 80, 80 are screwed on the upper part of the disc spring 72 through the washer 76. . In this state, the upper and lower nuts 80 , 80 are tightened toward the threaded shaft 74 , elastically deforming the six disc springs 72 , 72 . . . , and the disc spring mechanism 40 exhibits predetermined load characteristics.

The load characteristic of the disc spring mechanism 40 means that when the base 32 rolls with respect to the cabin floor surface 202 of the trailer 200, the upper end 34A of the tilt table 34 in the tilted state shown in FIG. load characteristics. For example, starting from the horizontal state of the base 32 shown in FIG. 27(A), when the base 32 rolls α° as shown in FIG. 27(B), as the disc spring on the right side shown in FIG. 27(B) The three disc springs 72, 72, 72 on the upper side of the bracket 52 of the mechanism 40 receive the swing and are elastically deformed, and at the same time serve as the lower side of the bracket 52 of the disc spring mechanism 40 on the left side shown in FIG. 27(B). The three disc springs 72 , 72 , 72 on the side are elastically deformed while being oscillated. At this time, the elastic restoring force (load characteristic) of the elastically deformed six disc springs 72 , 72 . . . Therefore, when the base 32 rolls by α°, it returns to the original horizontal state by the above-mentioned elastic restoring force, so that the base 32 does not roll more than α°. That is, in the loading device 30 of the embodiment, the allowable maximum swing angle for preventing the upper end 34A of the tilt table 34 from colliding with the wing 208 of the trailer 200 is set to α°.

Therefore, according to the loading device 30 of the embodiment, by the load characteristics of the disc spring mechanism 40, when the loading device 30 rolls, the upper end 34A of the tilt table 34 in the tilted state can be prevented from colliding with the wings 208 of the trailer 200, thereby preventing the Damage to the glass plate G due to the collision.

Next, the screw jack 44 for tilting the tilt table 34 will be described with reference to FIGS. 16 and 17 .

The screw jack 44 is composed of a cylinder 86, a screw (rod) 88, and a motor (rod drive unit) 90. The screw 88 that expands and contracts with respect to the cylinder 86 is expanded and contracted by the power of the motor 90, thereby changing the posture of the tilt table 34 as shown in FIG. 16 The inclined attitude shown and the horizontal attitude shown in Figure 17.

The cylinder 86 is provided swingably via a shaft 94 on a bracket 92 attached to the center portion of the side surface of the base 32 . The swing direction of the cylinder 86 is set as the tilt direction of the tilt table 34 .

The screw 88 is accommodated in the cylinder 86 and is provided so as to be able to expand and contract with respect to the cylinder 86 . The upper end of the screw 88 is rotatably supported via a shaft 98 by a bracket 96 provided on the lower surface of the tilt table 34 at a position serving as the upper end 34A of the tilt table 34 when tilted. In addition, the screw 88 is connected to the motor 90 through a gear (not shown) in the gear box 100 so as to be power-transmittable, and the rotational power of the motor 90 is transmitted through the gear to expand and contract with respect to the cylinder 86 . That is, when the screw rod 88 is extended, as shown in Figure 16, the screw rod 88 pushes up the tilt table 34, so that the tilt table 34 becomes an inclined posture, and when the screw rod 88 shrinks, as shown in Figure 17, the tilt table The stage 34 descends and becomes a horizontal posture. Following the tilting movement of the tilting table 34 at this time, the cylinder 86 swings around the shaft 94 , and the tilting operation of the tilting table 34 by the screw jack 44 is smoothly performed.

According to the screw jack 44 of the embodiment, the motor 90 extends the screw 88 with respect to the cylinder 86, so that the inclined table 34 can be easily brought into an inclined state, and the inclined table can be easily brought into a horizontal state by contracting the screw 88. .

Next, the lateral displacement restricting device 46 will be described with reference to FIGS. 18 and 19 .

The lateral displacement restricting device 46 is composed of a rubber or resin columnar pad 102 and a pad driving unit 104 . The pad driving unit 104 is composed of a motor 106, a universal joint 108, and the like. The motor 106 is fixed to a fixed bracket 110 on the side of the tilt table 34 by bolts 112 , and the input shaft 116 of the universal joint 108 is connected to the rotation shaft 114 of the motor 106 . The output shaft 118 of the universal joint 108 is connected to the shaft 122 of the pad holder 120 . The shaft 122 is rotatably supported by a bracket 124 fixed to the side surface of the tilt table 34 .

The pad bracket 120 has a lower bracket 126 connected to the shaft 122, and a reinforcing cylinder 128 and the respective lower portions of the pad 102 are attached to the lower bracket 126. As shown in FIG. The cylinder 128 and the shaft 122 are arranged on the same axis, and the pad 102 is arranged at a position where the central axis 102A is shifted by a predetermined amount from the central axis 122A of the shaft 122 . In addition, the upper parts of the cylindrical body 128 and the pad 102 are connected by an upper bracket 130 . Therefore, according to this lateral displacement restricting device 46 , when the motor 106 is driven, its power is transmitted from the universal joint 108 to the shaft 122 , and the pad holder 120 rotates around the shaft 122 . And, when the pad 102 moves to the position shown by the solid line in FIG. 18 and FIG. The restriction plate 39 of the tilt table 34 is pressed against the other edge portion 10A of the storage body 10 .

Therefore, according to the lateral displacement restricting device 46 configured in this way, the motor 106 moves the pad 102 to the position shown by the solid line in FIGS. The restriction plate 39 of the tilt table 34 can thus restrict the lateral deviation of the storage body 10 relative to the tilt table 34 (deviation in the traveling direction of the trailer 200 ) by the pad 102 and the restriction plate 39 . Thereby, lateral displacement of the storage body 10 with respect to the tilt table 34 can be easily prevented, and damage to the glass plate G caused by the lateral displacement can be prevented. And, when the storage body 10 is taken out from the tilt table 34, the pad 102 is retracted and moved from the other edge portion 10B of the storage body 10 as shown by the two-dot chain line in FIG. The resulting lateral offset limit is sufficient.

Next, the storage body fixing device 48 will be described with reference to FIGS. 20 and 21 .

The storage body fixing device 48 is a device for fixing the storage body 10 mounted on the tilt table 34 to the tilt table 34 and releasing the fixation, and is mainly composed of the hook 132 and the hook drive unit 134 . The hook 132 is movably supported by the tilt table 34 via a guide rail 136 fixed to the lower surface of the tilt table 34 at the position of the upper end 34A in the tilt posture (see FIG. 13 ). That is, the hook 132 is substantially L-shaped, and the pin 138 is provided at the front end thereof. The pin 138 is detachably engaged with an L-shaped engaging portion 140 provided on the base 12 through the opening 22 formed at the lower portion of the base 12 of the housing 10 . At this time, since the resin pad 141 provided on the engaging portion 140 is in close contact with the pin 138 , the tilt table 34 is pressed by the hook 132 without rattling.

On the other hand, the guide rail 136 is movably supported between the engaging position of the hook 132 with respect to the engaging portion 140 as shown in FIG. , an arc-shaped groove 144 is formed to guide the guide roller 142 rotatably provided at the base end portion of the hook 132 . Therefore, the hook 132 moves along the groove 144 to reciprocate between the engaged position shown in FIG. 20 and the retracted position shown in FIG. 21 . In addition, reference numeral 146 is a guide roller rotatably provided on the hook 132 , and the groove 144 is sandwiched between the guide roller 146 and the guide roller 142 so that the hook 132 can move stably.

The hook driving unit 134 is constituted by a cylinder 150 having a telescoping rod 148 . The base end of the power cylinder 150 is swingably connected to a bracket 152 fixed to the lower surface of the tilt table 34 via a pin 154 , and swings upward and downward relative to the tilt table 34 . Furthermore, the guide roller 142 of the hook 132 is rotatably connected to the front end portion of the rod 148 via a pin 156 .

Therefore, according to the storage body fixing device 48 of the above-mentioned structure, when the rod 148 is stretched and contracted by the power cylinder 150, the guide roller 142 advances along the groove 144 of the guide rail 136, so that the hook 132 is in the engaged position shown in FIG. In conjunction with the reciprocating movement between the retracted positions shown, the power cylinder 150 swings around the pin 154 as a fulcrum. Therefore, when fixing the storage body 10 to the tilt table 34, the rod 148 is contracted as shown in FIG. 20, and when the fixation is released, the rod 148 is extended as shown in FIG. This makes it possible to easily fix and unfix the storage body 10 with respect to the tilt table 34 .

Next, the inclined state maintaining device 50 will be described with reference to FIGS. 22 and 23 .

The inclined state maintaining device 50 is a device for maintaining the inclined table 34 in an inclined posture (refer to FIG. 13 ), and is composed of the following: a power cylinder (pin driving part) 160 having a telescopic pin 158; a cylindrical engaging part 164 forming There is a hole 162 for engaging the pin 158 .

The power cylinder 160 is fixed to the base 32 as shown in FIGS. 12 and 13 , and the pin 158 is arranged parallel to the shaft 36 . On the other hand, the engaging portion 164 is fixed downward on the lower surface of the tilt table 34, and when the tilt table 34 is changed to an inclined posture, as shown in FIG. In addition, a pad 166 is disposed on the hole 162 , and a V-groove 168 through which the guide pin 158 is inserted is formed on the upper surface of the pad 166 .

In addition, the pad 166 is biased in the direction of closing the hole 162 by the biasing force of the three-stage disc spring (spring force: 467kgf) 170 inserted into the engaging portion 164 , and passes through the long hole 172 and the pin 174 . The position restricting member restricts the position in the direction of the blocking hole 162 to the position shown in FIG. 23 . The elongated hole 172 is formed along the axial direction of the engaging portion 164 , and the pin 174 is fixed to the pad 166 and slidably engages with the elongated hole 172 . Therefore, when the urging force of the disc spring 170 acts on the pad 166, the pad 166 is pushed up in the direction of blocking the hole 162 by the urging force, but the initial position of the pad 166 is fixed due to the abutment of the pin 174 on the upper edge of the elongated hole 172. Set to the position shown in Figure 23. In this state, when the pin 158 is extended by the power cylinder 160 , the pin 158 enters from the entrance of the hole 162 , and the tapered surface 158A at the tip thereof is pressed against the V-groove 168 of the pad 166 . Then, the pad 166 is pushed down against the urging force of the disc spring 170 by the pushing force of the pin 158 , and the pin 158 protrudes from the outlet of the hole 162 as shown in FIG. 22 to engage with the hole 162 . As a result, the inclined table 34 is held by the base 32 in an inclined posture via the inclined state holding device 50 . At this time, since the pin 158 is pushed up by the urging force of the disc spring 170, it engages with the hole 162 without rattling.

Therefore, according to the tilted state maintaining device 50 configured as described above, the tilt table 34 can be easily held in the tilted state only by the power cylinder 160 extending the pin 158 and engaging with the hole 162 of the engaging portion 164 . Furthermore, when it is desired to change the posture of the tilt table 34 to a horizontal state, the pin 158 is contracted by the power cylinder 160 and the pin 158 is pulled out from the hole 162 of the engaging hole 164 .

Next, the operation of the loading device 30 configured as described above will be described.

In addition, the operations of the screw jack 44 , the lateral displacement restricting device 46 , the storage body fixing device 48 , and the tilted state maintaining device 50 are as described above, so their operations will be briefly described here.

First, when the storage body 10 is loaded on the loading device 30 mounted on the trailer 200, the tilt table 34 is tilted relative to the base 32 by the screw jack 44 to maintain a horizontal state, and in this state, a forklift 210 is used as shown in FIG. The container 10 is placed on the tilt table 34 . Thereby, even if it is a large glass plate G, the storage body 10 can be easily loaded on the tilt table 34. As shown in FIG.

Next, when the container 10 placed on the inclined table 34 is transported by the trailer 200, the lateral deviation of the container 10 relative to the inclined table 34 is firstly restricted by the lateral displacement restricting device 46 shown in FIGS. 18 and 19 . Thereby, even if vibration and shock are applied to the tilt table 34 from the trailer 200, the storage body 10 will not deviate laterally with respect to the tilt table 34, and thus damage to the glass plate G caused by the lateral shift can be prevented. Thereafter, the tilt table 34 is tilted by the screw jack 44 to change its posture to an inclined state. Next, the container 10 is fixed to the tilt table 34 by the hook 132 of the container fixing device 48 shown in FIGS. 20 and 21 . After this posture change, the storage body 10 is fixed to the tilt table 34 by the hook 132 of the storage body fixing device 48, so the storage body 10 will not deviate or fall off from the tilt table 34, thereby the storage body 10 can be changed stably to Leaning stance. Next, the tilt table 34 is held in the tilted state shown in FIG. 13 by the pin 158 of the tilted state holding device 50 shown in FIGS. 13 and 14 . The transportation preparation of the storage body 10 is completed by the above operation.

In the mode of transportation by the loading device 30 , since the storage body 10 is transported in an inclined state, even a large glass plate G can be transported by the trailer 200 in accordance with current road traffic regulations. In addition, since the inclined table 34 is held in an inclined state by the inclined state maintaining device 50 , even if vibration and roll during transportation are transmitted to the base 32 , the inclined table 34 does not collide with the base 32 . Therefore, damage to the glass plate G due to the above-mentioned collision can be prevented.

In addition, when the storage body 10 is transported by the trailer 200, the vibration transmitted from the trailer 200 to the loading device 30 is attenuated by the vibration isolators 38, 38, . Since it is transmitted to the loading device 30, the damage of the glass plate G by the said vibration can be prevented. In addition, the roll applied to the loading device 30 from the trailer 200 is combined with the lateral displacement preventing effect of the lateral displacement restricting device 46, and the plurality of disc spring mechanisms 40 arranged between the base 32 and the pedestal plate 214 of the trailer 200 The disc springs 72, 72... are elastically deformed to suppress the amount of roll, so that the storage body 10 can be transported stably, and damage to the glass plate G caused by the roll can be prevented.

Therefore, according to the loading device 30 of the embodiment, even a large-sized glass plate G can be efficiently loaded, and the damage prevention means composed of the lateral displacement restricting device 46, the vibration isolator 38, and the disc spring mechanism 40 can be used. Therefore, it is possible to reliably prevent damage to the glass plate G caused by vibration and impact during transportation.

On the other hand, according to the trailer 200 of the embodiment, the loading device 30 is mounted so that the axial direction of the shaft 36 pivotally supporting the tilt table 34 becomes the traveling direction, and transports the container 10 . By mounting the loading device 30 on the trailer 200 in this posture, even a large glass plate G can be conveyed in accordance with current road traffic regulations.

Although this application was detailed and demonstrated with reference to the specific embodiment, it cannot be overemphasized that various changes and corrections can be added without deviating from the mind and range of this invention for those skilled in the art. This application is based on the JP Patent application (Japanese Patent Application No. 2010-005069) for which it applied on January 13, 2010, The content is used as a reference.
