Description

The present invention relates to an apparatus for manufacturing a wooden loading platform.

Conventionally, when transporting a large number of large steel plates to a destination (delivery point), a wooden loading platform called a skid, which is made of lumber assembled in a grid pattern, is used, and the steel plates are stacked and placed on this wooden loading platform and secured to the wooden loading platform with iron straps (iron bands). After that, a lifting wire is hung around the wooden loading platform, and the steel plates are hoisted and transported onto a vehicle or other means of transportation. However, because these wooden loading platforms are large enough to accommodate large steel plates, and the transportation costs for returning them are high, most of them are disposable types.

For this reason, these disposable wooden loading platforms are manufactured at the lowest possible cost, so the connections between the timbers are simply fixed by driving nails into the intersections where the timbers intersect. However, when the timbers are transported to their destination, the connections between the timbers are maintained by the steel bands that secure the steel plates as described above, so the connections (nailed parts) do not loosen, and there are no problems with this type of simple connection.

However, such disposable wooden loading platforms are often stored at the delivery destination with the steel plates still stacked on them, and when the steel plates are to be used, they are often moved to the location where they are to be used while still stacked on the wooden loading platform.

When transporting these products to their destinations, they are often moved short distances and are therefore sometimes transported using hoisting wires or forklifts without being secured with steel straps. If the steel plates are not secured with steel straps, the weight of the steel plates places a strain on the joints (nailed joints), and if the joints are secured only with nails at the intersections, the nailed joints will loosen, causing problems such as the joints between the square timbers coming loose.

Therefore, in order to prevent the above-mentioned problems, the applicant has invented a wooden receiving platform that not only uses nails to secure the intersections, but also uses metal fittings to secure the ends of the timber that forms the legs and the sides of the timber that forms the receiving part, thereby reinforcing the joint strength.

However, if the fittings are installed manually by a worker, it takes time and effort, and increases manufacturing costs.

The present invention has been developed in consideration of the current situation as described above, and has an object to provide a wooden loading tray manufacturing device that can efficiently manufacture durable wooden loading trays at low cost.

The gist of the present invention will be explained with reference to the attached drawings.

Specifically, the first conveying means 6 is made up of four chain conveyors 6a arranged in parallel and driven by servo motors (not shown), and is configured to transport the members (wooden leg material 31 and wooden cargo receiving material 32) placed on each chain conveyor 6a in a tactile manner.

The first conveying means 6 is also configured so that the spacing between the chain conveyors 6a can be adjusted, and the spacing can be set to an appropriate interval depending on the number of wooden load-receiving materials 32 used on one wooden load-receiving platform 30.

The first clamping means is configured to position and fix (clamp) the wooden leg material 31 and wooden cargo receiving material 32 transported by the first transporting means 6 in a predetermined state.

Specifically, the first clamping means is provided below the first fixing means 1, and is configured to position each wooden cargo receiving material 32 in a predetermined position in an appropriate state, and to position the wooden leg material 31 set on the wooden cargo receiving material 32 at the predetermined position of the wooden cargo receiving material 32 so that it is perpendicular to the wooden cargo receiving material 32 and so that the end face of the wooden leg material 31 is flush with the side of the outer wooden cargo receiving material 32, thereby maintaining the positioning state of the wooden leg material 31 and the wooden cargo receiving material 32.

The first fixing means 1 also includes a plurality of (four in this embodiment) first nail driving portions 10 and a first nail supply portion (not shown) that supplies nails 34a to the first nail driving portions 10.

In addition, each first nail driving unit 10 is configured to be movable in the width direction (Y direction perpendicular to the conveying direction of the first conveying means 6) and in the vertical direction (Z direction) of the nail driving device 7 (the width direction (X direction) of the nail driving device 7 is fixed), and as shown in Figure 2, it is provided directly above each chain conveyor 6a of the first conveying means 6 and is configured to be adjustable in accordance with the adjustment movement of the parallel spacing of the chain conveyors 6a.

Regarding the nailing device 7, the number of chain conveyors 6a constituting the first transport means 6 and the number of first nailing sections 10 of the first fixing means 1 are not limited to this embodiment and can be modified as appropriate.

As shown in Figures 2 and 4, the metal fitting attachment device 9 of this embodiment is equipped with a second conveying means 8, a second fixing means 2, and a second clamping means (not shown), and is configured to connect and reinforce the wooden legs 31 and wooden load-receiving material 32 using metal fittings 33 to members (hereinafter referred to as "grid members") assembled in a grid shape (formed into the shape of a load-receiving table) via a nailing device 7.

Specifically, the second conveying means 8 is made up of multiple drive rollers 8a arranged side by side, and is configured to convey the lattice member that is sent out from the nailing device 7 and placed on the drive rollers 8a to the second fixing means 2 while maintaining the proper conveying position.

The second conveying means 8 is also provided with a guide section 11 on one side in the width direction, and the wooden cargo receiving material 32 is moved by the guidance of this guide section 11, so that the lattice-shaped member is conveyed in the appropriate conveying position.

Specifically, the guide section 11 is composed of multiple guide rollers 11a arranged in two rows along the conveying direction, and these guide rollers 11a clamp and guide the outermost wooden cargo receiving material 32, thereby fixing the position of the lattice member and preventing it from shifting in the width direction, so that the lattice member is conveyed to the second clamping means in the correct position and in the correct posture.

More specifically, in this embodiment, the guide section 11 is configured so that the guide rollers 11a arranged on the inside are movable in the width direction (the direction perpendicular to the conveying direction of the second conveying means 8), and the distance between the guide rollers 11a in the outer row and the guide rollers 11a in the inner row can be appropriately adjusted according to the width (thickness) of the wooden cargo receiving material 32 to be clamped and guided.

The second clamping means is provided in front of the second fixing means 2, which will be described later, and is configured to properly position the lattice member in a predetermined position and maintain this positioning state so that the lattice member does not shift position during the metal fitting installation work using the second fixing means 2.

As shown in Figure 5, the second fixing means 2 comprises a metal fitting storage section 3 for stacking and storing a plurality of metal fittings 33 formed in a flat plate shape, a metal fitting transport mechanism 4 for removing the metal fittings 33 stored in the metal fitting storage section 3 and transporting them to a predetermined position, a second nail driving section 5 for nailing and fixing the metal fittings 33 transported to the metal fitting transport mechanism 4 to the end face of the wooden leg material 31 and the side of the wooden load-receiving material 32, and a second nail supply section (not shown) for supplying nails 34b to the second nail driving section 5. As shown in the figure, these are arranged in opposing positions on both the left and right sides of the metal fitting mounting device 9 and are configured to simultaneously mount metal fittings on both sides of the lattice-shaped member.

Specifically, the metal fitting transport mechanism 4 comprises a first metal fitting transport section 4a, a second metal fitting transport section 4b and a third metal fitting transport section 4c, and the first metal fitting transport section 4a is configured to take out one of the metal fittings 33 stored in the metal fitting storage section 3 and transport it to the second metal fitting transport section 4b, as shown in Figures 5 and 6, and the second metal fitting transport section 4b is configured to receive the metal fitting 33 from the first metal fitting transport section 4a and move the position of the metal fitting 33 towards the third metal fitting transport section 4c, as shown in Figure 7, and the third metal fitting transport section 4c is configured to receive the metal fitting 33 from the second metal fitting transport section 4b and abut the metal fitting 33 in a straddling state against the end face of the wooden leg material 31 and the side surface of the wooden load receiving material 32, as shown in Figures 7 to 9.

More specifically, the first metal fitting transport unit 4a and the second metal fitting transport unit 4b are configured to hold the metal fitting 33 by suction adsorption, and the third metal fitting transport unit 4c is configured to hold the metal fitting 33 by magnetic adsorption.

In detail, the first metal fitting transport section 4a is equipped with a moving section 13 having a suction and adsorption section 12 that holds the metal fitting 33 by suction and adsorption, and a guide section 14 that guides the movement of this moving section 13. The suction and adsorption section 12 is provided so as to be movable in the vertical direction, and is configured to adsorb and hold the metal fitting 33 stored in the metal fitting storage section 3 by moving downward, and to move to a metal fitting transfer position with the second metal fitting transport section 4b by moving the moving section 13.

The second metal fitting transport section 4b is equipped with a rotating section 16 having a suction and adsorption section 15 that holds the metal fitting 33 by suction and adsorption, and a rotating shaft section 17 that guides the rotational movement of the rotating section 16, and is configured to receive the metal fitting 33 from the first metal fitting transport section 4a, rotate 90°, and move the metal fitting 33 toward the third metal fitting transport section 4c.

The third metal fitting transport section 4c is equipped with a moving section 19 having a magnetic attraction section 18 that holds the metal fitting 33 by magnetic attraction, and a drive section 20 for transporting the moving section 19. The magnetic attraction section 18 is formed in a flat plate shape and has a through hole 18a into which the ejection section that ejects the nail 34b of the second nail driving section 5 is inserted. The magnetic attraction section 18 is movable in the front-rear direction, and is magnetically attracted to the metal fitting 33 held by the suction and adsorption section 15 of the second metal fitting transport section 4b by moving forward, and is configured to receive the metal fitting 33 by releasing the suction of the suction and adsorption section 15, move backward, and then lower the metal fitting 33 to a predetermined position by moving downward the moving section 19, and again move forward the magnetic attraction section 18 to abut the metal fitting 33 in a straddling state against the end face of the wooden leg material 31 and the side of the wooden load receiving material 32.

In this embodiment, as described above, the metal fittings 33 are magnetically attracted in the third metal fitting transport section 4c, so the metal fittings 33 used are made of a magnetically attractable metal (e.g., SUS430).

Moreover, with regard to the metal fitting transport mechanism 4, instead of providing the second metal fitting transport section 4b, a rotation function may be added to the first metal fitting transport section 4a, and the first metal fitting transport section 4a may hand over the metal fitting 33 to the third metal fitting transport section 4c. Also, by changing the layout of the transport section, the second metal fitting transport section 4b may be made unnecessary.

The second nail driving unit 5 also has four ejection units 5a that eject nails 34b, and is configured to drive four nails 34b simultaneously.

The second nail driving section 5 is also configured to be movable in the front-rear direction (configured to be able to move toward and away from the side of the lattice member) and is configured to move in conjunction with the front-rear movement of the third metal fitting transport section 4c.

Specifically, the second nail driving unit 5 moves forward together with the third metal fitting transport unit 4c, and continues to move forward even after the third metal fitting transport unit 4c stops moving by bringing the metal fitting 33 into contact with the side of the lattice member. As shown in FIG. 9, the ejection unit 5a is inserted into the through hole 18a in the magnetic attraction unit 18, and the magnetic attraction unit 18 is pressed, so that the metal fitting 33 is brought into close contact with the side of the lattice member, and then the nail 34b is ejected and driven.

The number of nails 34b ejected from the second nail driving section 5 can be changed as needed.

Next, we will explain the manufacturing method of the wooden cargo tray 30 using the wooden cargo tray manufacturing device of this embodiment configured as described above.

First, the worker selects the product data corresponding to the wooden loading platform 30 to be manufactured from preregistered product data in the control device (not shown) that controls the operation of the nailing device 7 and the metal fitting attachment device 9.

Next, the number of wooden receiving materials 32 required to form the receiving section (panel section) of the wooden receiving platform 30 is set on the chain conveyor 6a of the first conveying means 6 of the nailing device 7, and then the required number of wooden legs 31 are set at predetermined positions on the wooden receiving materials 32 set on the chain conveyor 6a so that they intersect with the wooden receiving materials 32, and then the work start operation is performed.

When setting the wooden leg 31 on the wooden load-receiving material 32, the surface with the groove 31a for looping the strap iron around it is set with the surface facing up. Also, the wooden leg 31 does not need to be set at a precise position perpendicular to the wooden load-receiving material 32, but can be set roughly (because it is set in the correct position by the first clamping means of the nailing device 7 after work begins).

The above-mentioned operation start operation activates the nailing device 7, and the first conveying means 6 transports the wooden load-receiving material 32 and the first wooden leg 31 to the first clamping means. The first wooden leg 31 set on the wooden load-receiving material 32 is positioned at a predetermined position so that it is perpendicular to the wooden load-receiving material 32 and the end face of the wooden leg 31 is flush with the side of the outer wooden load-receiving material 32. While maintaining the above-mentioned positioning of the first wooden leg 31 relative to the wooden load-receiving material 32, the first fixing means 1 drives two nails 34a into each intersection where the first wooden leg 31 and the wooden load-receiving material 32 intersect, and the first wooden leg 31 and the wooden load-receiving material 32 are nailed together.

After the first wooden leg 31 has been nailed, the first conveying means 6 moves forward by tactile conveyance, and the second and third wooden legs 31 are positioned and nailed in the same manner.

Next, after the wooden legs 31 and wooden cargo receiving material 32 have been nailed together using the nailing device 7, the wooden legs 31 and wooden cargo receiving material 32 (lattice-shaped members) assembled in a lattice shape are sent to the metal fittings mounting device 9 connected to the nailing device 7, where metal fittings 33 are attached to the sides to reinforce the joint (connection) between the wooden legs 31 and wooden cargo receiving material 32.

Specifically, the wooden cargo receiving material 32 located at the outermost position on one side of the width direction of the lattice member sent out from the nailing device 7 is clamped by the guide portion 11 of the second conveying means 8 (clamped between the guide rollers 11a of the guide portion 11), and conveyed to the second fixing means 2 while maintaining the proper posture and position of the lattice member.

The lattice member transported to the second fixing means 2 is then positioned and fixed in a predetermined state by the second clamping means, and the second fixing means 2 attaches the metal fittings 33 to the predetermined metal fitting mounting positions, and the end faces of the wooden legs 31 and the sides of the wooden cargo receiving material 32 are connected and fixed by the metal fittings 33.

In detail, first, the first metal fitting transport unit 4a operates to pick up one metal fitting 33 stored in the metal fitting storage unit 3 by suction and move it horizontally to the metal fitting transfer position with the second metal fitting transport unit 4b.

Then, the second metal fitting transport section 4b sucks and receives the metal fitting 33 held by the first metal fitting transport section 4a, and rotates the rotating section 16 to flip the metal fitting 33 90° and place it on the side of the third metal fitting transport section 4c.

Then, the third metal fitting transport unit 4c magnetically attracts and receives the metal fitting 33 held by the second metal fitting transport unit 4b, and moves downward to a position opposite the metal fitting attachment position of the lattice member.

Next, the third metal fitting transport part 4c holding the metal fitting 33 and the second nailing part 5 move forward, and the metal fitting 33 held by the third metal fitting transport part 4c is brought into contact with the side of the lattice member (straddling the end face of the wooden leg material 31 and the side of the wooden load-receiving material 32). After this metal fitting 33 comes into contact with the side of the lattice member, the second nailing part 5 moves forward and presses the magnetic attraction part 18 of the third metal fitting transport part 4c holding the metal fitting 33, bringing the metal fitting 33 into intimate contact with the side of the lattice member. After that, the second nailing part 5 ejects and drives the nail 34b, and the metal fitting 33 is nailed and fixed in place.

After the above work is performed at the hardware mounting device 9 for the specified hardware mounting position, the work is completed and the completed wooden loading platform 30 is sent onto the transport platform 40 connected to the hardware mounting device 9 and collected by a worker.

When collecting the completed wooden cargo tray 30, for example, an inversion device may be connected to the metal fitting attachment device 9, and the wooden cargo tray 30 may be automatically stacked and stored by this inversion device.

As this embodiment is configured as described above, it is a wooden cargo tray manufacturing device that can efficiently manufacture a highly durable wooden cargo tray 30 at low cost. Furthermore, the wooden cargo tray 30 of this embodiment manufactured as described above using this wooden cargo tray manufacturing device is a highly durable wooden cargo tray 30 that has a simple configuration and can be manufactured at low cost.

The present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
