Description

  The present invention relates to a sheet glass loading method and a loading apparatus, and more particularly to a technique for loading a sheet glass in a container by fixing the sheet glass to a jig for transporting the sheet glass.

  For example, Patent Document 1 proposes that when a large amount of glass sheet is transported by land or sea, the glass sheet is loaded in a container and transported. According to the same document, a transportation jig having a trapezoidal cross-section projecting portion extending upright from a base member is installed in a container, the plate glass is lifted and the plate glass is put into the container from the upper opening of the container. In the container, a plurality of plate glasses are stood and fixed on a pair of inclined surfaces of the transportation jig, and the plate glasses are loaded in the container.

Japanese Patent Laid-Open No. 7-2287

  However, as in Patent Document 1, in the case of performing the standing and fixing work of the plate glass in the container, it is necessary to secure a work space in the container, and thus there is a problem that it is difficult to increase the loading space of the plate glass. Moreover, when performing the same work, since the work is performed in a narrow space in the container, there is a problem that the burden on the worker is heavy.

  On the other hand, a method is conceivable in which, after a plurality of plate glasses are erected and fixed to a transportation jig outside the container, the transportation jig is lifted with a crane and placed in the container from the upper opening of the container to load the sheet glass. In this case, the worker does not have to work in the container, but an open top “open top container” having an opening in the upper part of the container must be prepared, which increases costs. For example, when a large plate glass for construction is bundled and transported, the weight of the plate glass becomes 10 to 20 tons, and this weight is added to the transport jig when lifting. For this reason, since it is necessary to increase the strength of the transportation jig so that it can withstand the weight of the plate glass when it is lifted, there is a problem that the transportation jig becomes large and equipment costs increase.

  The problem to be solved by the present invention is to eliminate the need for an operator to enter the container and to increase the loading space for the plate glass in the container.

  A transportation jig comprising a support member having a trapezoidal cross section to be erected on the base member is placed on the gantry, and a plurality of plate glasses are erected and fixed to a pair of inclined surfaces of the support member of the transportation jig. Containers are connected in series, the height of the top surface of the gantry and the floor surface of the container are matched, and the transportation jig is slid onto the top surface of the gantry and the floor surface of the container by power means, and the transportation jig is pushed into the container. And plate glass.

  According to this, since a plurality of plate glasses are stood and fixed on a transportation jig on the gantry, the transportation jig is stored in the container, so a general-purpose marine container (dry container) having no opening at the top is used. Even in such a case, it is not necessary to provide a space in the container where the sheet glass is stood and fixed. Furthermore, by aligning the height of the top surface of the gantry with the height of the container floor surface, the transport jig on the gantry can be slid and pushed into the container so that the plate glass can be loaded. Compared with the case of loading in a container, there is no hanging jig or the like, and since there is no need to increase the strength by increasing the thickness of each part of the transportation jig, a small transportation jig can be used. By these, since the loading space of the plate glass in a container can be increased, the load amount of the plate glass of a container can be increased and the burden of an operator can be reduced.

  On the other hand, the sheet glass loading method of the present invention includes a transportation jig in which a plurality of sheet glasses are stood and fixed on a pair of inclined surfaces of a trapezoidal support member standing on a base member, and a bottom surface of the transportation jig. A resin plate member to be attached to the base, a base on which the transport jig is placed, an adjustment member for adjusting the height of the top surface of the base and the floor of the container connected to the base, and a transport jig Can be realized by a plate glass stacking device provided with power means such as a conveyance vehicle for sliding the glass plate into the container by sliding the upper surface of the gantry and the floor surface of the container.

  According to this, since a resin plate member having a small frictional resistance with the container floor surface is provided on the bottom surface of the transportation jig, and the transportation jig is easily slipped on the container floor surface, Can be easily pushed into.

  In this case, a roller conveyor can be attached to the upper surface of the gantry to slide the transportation jig on which the plate glass is fixed. According to this, since the transportation jig on which the plate glass is fixed is easily slid on the frame by the roller conveyor, the efficiency of the loading operation is improved.

  Further, the support member and the base member of the transportation jig can be formed to be detachable. According to this, after the plate glass is loaded and unloaded at the transportation destination, the supporting member can be detached from the base member and the transportation jig can be disassembled, so that a plurality of transportation jigs can be accommodated in one container and taken home. And if the transport jig brought home is reassembled, it can be used any number of times. Moreover, since the strength of the transportation jig can be simplified as compared with the transportation jig used for lifting with a crane, the transportation cost can be improved by simplifying the structure of the transportation jig itself and reducing the weight.

  ADVANTAGE OF THE INVENTION According to this invention, the necessity for a worker to enter in a container can be eliminated, and the loading space of the plate glass in a container can be increased.

In addition, FIG. 1 shows the state of the plate glass 5 before and after being loaded on the container 11 for the sake of easy understanding.

  The transportation jig 7 is made of a metal such as steel. The base member 1 of the transport jig 7 includes, for example, a plurality of columnar members 17 extending in the longitudinal direction, a columnar member 18 shorter than the columnar member 17, and a plurality of columnar members connected orthogonally to the columnar member 17. A plurality of columnar members 21 connected so as to form intersections between the members 19 and the columnar members 17 and 19 are formed in a flat shape so that the plate glass 5 can be placed. Resin-made plate members 27 and 29 are attached to the back surface of the base member 1 (the bottom surface of the transportation jig 7) by, for example, screws. The plate members 27 and 29 are made of a resin having a low frictional resistance against the floor surface of the container 11, for example, nylon. The plate member 27 is formed in accordance with the width of each columnar member 17, and a plurality of plate members 27 are attached along the columnar member 17 at intervals. Here, the plate member 29 has a large area and is attached in a line along the columnar member 18. The area can be optimally designed in consideration of the size of the plate members 27 and 29 and the weight of the loaded glass.

  The support member 3 of the transport jig 7 is formed by a plurality of column members 23 erected on the base member 1 and a plurality of beam members 25 spanned between the column members 23. The support member 3 is formed by the pillar member 23 and the beam member 25 so that a cross section in a direction orthogonal to the extending direction of the beam member 25 is formed in a trapezoidal shape, and the plate glass 5 can be stood and fixed on a pair of trapezoidal inclined surfaces. ing. The trapezoidal pillar members 23 are erected at three positions when viewed from the side in this embodiment. In addition, the number of the column members 23 is not limited to this embodiment, For example, it can be made to stand in five places.

  As shown in FIG. 7, a screwing portion 28 is provided at a connection position between the base member 1 and the support member 3 of the transportation jig 7. The screwing portion 28 is provided with a pair of plate members 30 that are erected so as to face the columnar member 19 of the base member 1. Then, the column member 23 of the support member 3 is inserted between the plate members 30, the screw holes formed in the column member 23 and the screw holes formed in both plate members 30 are aligned, and these screw holes are penetrated. Thus, the base member 1 and the support member 3 are detachably connected by inserting the screw 32 and screwing the nut 34 together.

  The gantry 9 on which the transportation jig 7 is placed includes a plurality of columnar members 31 extending along the longitudinal direction, a plurality of columnar members 33 connected orthogonally to the columnar members 31, and the columnar members 31. , 33 is provided with a net-like member 35 attached so as to cover the plane formed. Thus, a rectangular placement surface 36 on which the transportation jig 7 is placed on the gantry 9 is formed. A plurality of roller conveyors 37 are attached to the mounting surface 36 of the gantry 9 along the longitudinal direction of the gantry 9 to slide the transportation jig 7 on which the plate glass 5 is fixed. The roller conveyor 37 is attached to correspond to the columnar members 17 and 18 of the base member 1. Each roller conveyor 37 is formed by a plurality of rollers that are rotatably supported along the extending direction. In FIG. 4, for ease of illustration, among the plurality of roller conveyors 37, a plurality of rollers in which only one roller conveyor 37 is fixed are illustrated, and the description of the rollers is omitted for the other roller conveyors 37.

  On the back side of the gantry 9, hydraulic jacks 13 that can extend and contract in the vertical direction are attached to each corner of the gantry 9, for example. Thus, the height of the gantry 9 can be adjusted by extending and contracting each hydraulic jack 13. Further, wheels 41 are attached to the back side of the gantry 9 so as to be adjacent to the hydraulic jacks 13, and the gantry 9 can be moved by supporting the gantry 9 by the wheels 41 by contracting the hydraulic jacks 13. It has become.

  The transport jig 16 that connects the transport jig 7 and the transport vehicle 15 has a connection portion 42 that can be connected to the transport jig 7 at one end in the longitudinal direction, and can be connected to the transport vehicle 15 at the other end. A connecting portion 44 is formed. The transport jig 16 is formed to have a length dimension that allows the transport jig 7 on the mounting surface 36 of the gantry 9 to be pushed into a predetermined position in the container 11.

  A usage example of the stacking apparatus of the present embodiment configured as described above will be described together with a method of stacking plate glasses. First, the transportation jig 7 is placed on the mount 9. Then, a plate glass 5, for example, a plate glass 5 formed by bundling a plurality of large glass plates for construction and winding a buffer material is placed on the base member 1 of the transportation jig 7. At this time, in order to prevent breakage of the plate glass 5, a buffer material such as a wooden plate is disposed on the base member 1, and the plate glass 5 is placed on the buffer material. Then, a cushioning material such as polystyrene foam is disposed on the inclined surface of the support member 3, and the plate glass 5 is leaned against the cushioning material. Another plate glass 5 is laid on the laid plate glass 5 via a cushioning material. By repeating this operation, as shown in FIG. 9, a plurality of plate glasses 5 are leaned against the transportation jig 7.

  After a predetermined number of plate glasses 5 are leaned, a plate-shaped glass presser 43 is pressed against the plate glass 5 located on the surface via a buffer material. Then, the entire transportation jig 7 including a plurality of plate glasses 5 erected from above the glass presser 43 is secured with, for example, a steel band 45. Thereby, the several glass plate 5 leaning on the jig | tool 7 for transport is fixed. In addition, in this embodiment, the quantity of the plate glass 5 on which each inclined surface leans is match | combined so that the weight of the plate glass 5 added to each inclined surface of the supporting member 3 may be balanced.

  Next, the container 11 on which the plate glass 5 is loaded is arranged at the end in the longitudinal direction of the gantry 9 and is continuously provided. At this time, the height of the gantry 9 is adjusted in advance by the hydraulic jack 13 so that the upper surface of the gantry 9 and the floor surface of the container 11 are matched. Further, if necessary, a plate member is spanned between the gantry 9 and the container 11 to adjust the difference in height between the upper surface of the gantry 9 and the floor surface of the container 11 and close the gap between the gantry 9 and the container 11. . After matching the height of the upper surface of the gantry 9 and the floor surface in the container 11, the transport vehicle 15 is advanced in the direction of arrow 47 in FIG. The force in the direction of the arrow 47 is applied to the transportation jig 7 to which the plate glass 5 is fixed via the transportation jig 16. Thereby, the transportation jig 7 slides on the mounting surface 36 of the gantry 9. At this time, since the transportation jig 7 slides on the roller conveyor 37, the transportation jig 7 can easily slide on the mount 9, and the efficiency of the loading operation of the plate glass 5 can be improved. Further, even if the transportation jig 7 slides toward the side surface side of the gantry 9, the transportation jig 7 extends along the pushing direction of the transportation jig 7 on both side surfaces of the base member 1 of the transportation jig 7. Since a guide member 39 is provided and the guide member 39 abuts against a sliding portion (not shown) provided on the gantry 9 and the sliding direction can be regulated, the transportation jig 7 is prevented from falling off the gantry 9. it can.

  The transportation jig 7 pushed into the container 11 from the gantry 9 slides on the floor surface of the container 11 and is pushed into the container 11. At this time, the floor surface of the container 11 is made of wood, and resin plate members 27 and 29 that are easy to slide on the wooden floor surface are attached to the bottom surface of the transport jig 7. The container 11 can be easily slid and the transportation jig 7 can be easily pushed into the container 11. Then, the transportation jig 7 is brought into contact with a stopper (not shown) provided in the container 11, and the transportation jig 7 is stopped at a predetermined position in the container 11. Thereafter, the base member 1 is fixed to the floor surface of the container 11 so that the transportation jig 7 does not move in the container 11. Thereby, as shown in FIG. 10, the plate glass 5 can be loaded on the container 11. The container 11 loaded with the plate glass 5 is loaded on, for example, a transport ship by a heavy machine such as a crane.

  According to this, since the plurality of plate glasses 5 are stood and fixed on the transportation jig 7 on the gantry 9 outside the container 11, the transportation jig 7 is stored in the container 11. It is not necessary to provide a space for performing the above in the container 11. Further, by matching the height of the top surface of the gantry 9 and the floor surface of the container 11, the transport jig 7 on the gantry 9 can be slid to push the pushing plate glass 5 into the container 11. Compared with the case where the plate glass 5 is loaded in a container having an open top surface, a small transportation jig without a hanging jig can be used. By these, since the loading space of the plate glass 5 in the container 11 can be increased, the loading amount of the plate glass 5 of the container 11 can be increased.

  In this embodiment, the roller conveyor 37 is disposed on the gantry 9. However, when the gantry 9 is used as the transportation jig 7, the plate members 27 and 29 are attached to the bottom surface of the transportation jig 7. Can be made of a resin having a low frictional resistance against the mounting surface 36 of the gantry 9, the roller conveyor 37 can be omitted.

  The transport vehicle 15 for pushing the plate glass 5 into the container 11 can be a well-known heavy machine capable of moving a heavy object in the horizontal direction in addition to a towing vehicle such as a tractor.

  Further, the height adjustment of the mounting surface 36 of the gantry 9 and the floor surface of the container 11 is not limited to the present embodiment. For example, the container 11 is supported by an extendable hydraulic jack and the height of the container 11 is adjusted. A known method such as a method, a method of adjusting the height by placing a plate between the gantry 9 or the container 11 and the ground can be used.

  By the way, the operation | work which unloads the plate glass 5 which arrived at the transport destination is illustrated using FIG. The container 11 loaded with the plate glass 5 is connected to a predetermined platform 101 using a trailer X. At this time, the trailer X is supported by the extendable hydraulic jack 103, and the hydraulic jack 103 is expanded and contracted so that the floor surface height of the container 11 and the upper surface height of the platform 101 are matched. A chill hole 107 having a hydraulic pump 102 and capable of pulling the wire 105 by hydraulic pressure is fixed to the platform 101 by a pulling hook 109. Then, one end of the wire 105 is connected to the chill hole 107 and the other end is connected to the transportation jig 7. In this state, the transportation jig 7 is pulled in the direction of the arrow 111 while sliding the transportation jig 7 on the floor surface of the container 11 and the upper surface of the platform 101. And after the plate glass 5 is pulled out from the container 11, the securing of the plate glass 5 is cancelled | released, and the plate glass 5 is lifted with a crane etc. and taken out. If the platform 101 is not available at the wholesale area, the gantry 9 can be used. In that case, the transportation jig 7 on which the plate glass 5 is placed is pulled out from the container 11 to the upper surface of the gantry 9 in the reverse procedure to the loading method described above.

  When the transportation jig 7 with the plate glass 5 lowered is brought back, the screw 32 and the nut 34 are unscrewed, the support member 3 is removed from the base member 1, and the transportation jig 7 is disassembled. And as shown in the figure, the upper and lower sides of the support member 3 are combined alternately, and the base member 1 is arranged in the gap, so that, for example, four transportation jigs 7 can be brought home in one container 11.
