Description

[Technical Field]

[0001] The present invention relates to a wooden receiving platform manufacturing device. Placement and How to manufacture a wooden loading platform By law It is related to. [Background technology]

[0002] 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 square timbers 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 bands (iron bands). After that, a lifting wire is hung around the wooden loading platform and the steel plates are lifted and transported onto a vehicle or other means of transportation. However, these wooden loading platforms are large enough to accommodate large steel plates, and because the transportation costs for returning them are high, most of them are disposable.

[0003] Therefore, in order to manufacture these disposable wooden loading platforms at the lowest possible cost, the timbers are joined simply by nailing them together at the intersections where the timbers intersect. However, when the timbers are transported to their destination, the timbers are held together by the steel bands that secure the steel plates, as mentioned above, so the joints (nailed joints) do not loosen, and there are no problems with this type of simple joining.

[0004] However, such disposable wooden receiving trays 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 receiving tray.

[0005] When transporting these products to their destinations, they are often moved short distances and are therefore sometimes transported using lifting 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 puts stress on the joints (nailed joints), and if the joints are only secured with nails at the intersections, the nailed joints will loosen, causing the joints between the timbers to come loose.

[0006] Therefore, in order to prevent the above-mentioned problems, the applicant has discovered a wooden cargo receiving platform that not only fastens the intersections with nails, but also attaches metal fittings to the end faces of the square timbers that form the legs and to the sides of the square timbers that form the cargo receiving sections, joining the two with the metal fittings to reinforce the joint strength. Summary of the Invention [Problem to be solved by the invention]

[0007] However, if the fittings are manually attached by a worker, it takes time and effort, and the manufacturing cost increases.

[0033] 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.

[0034] Specifically, each first nailing unit 10 has two ejection units that eject nails 34a and is configured to drive two nails 34a at the same time.

[0035] In addition, each first nailing unit 10 is configured to be movable in the width direction of the nailing device 7 (Y direction perpendicular to the conveying direction of the first conveying means 6) and in the vertical direction (Z direction) (the width direction (X direction) of the nailing device 7 is fixed), and as shown in Figure 2, is provided directly above each chain conveyor 6a of the first conveying means 6, and is configured to be adjustable and movable in accordance with the adjustment and movement of the parallel arrangement spacing of the chain conveyors 6a.

[0036] Regarding the nailing device 7, the number of chain conveyors 6a constituting the first conveying 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 in design as appropriate.

[0037] In addition, as shown in Figures 2 and 4, the metal fitting mounting 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 fix (reinforce and fix) wooden leg material 31 and wooden load-receiving material 32 to members (hereinafter referred to as "lattice-shaped members") assembled in a grid shape via a nailing device 7 (formed in the shape of a load-receiving table) using metal fittings 33.

[0038] Specifically, the second conveying means 8 is composed of a plurality of drive rollers 8a arranged in parallel, and is configured to convey the grid-like member sent out from the nailing device 7 and placed on these drive rollers 8a to the second fixing means 2 while maintaining the appropriate conveying posture.

[0039] In addition, the second conveying means 8 is provided with a guide section 11 on one side in the width direction, and the wooden cargo receiving material 32 moves under the guidance of this guide section 11, so that the lattice-shaped member is conveyed in an appropriate conveying position.

[0040] Specifically, the guide section 11 is composed of a plurality of guide rollers 11a arranged in two rows along the conveying direction, and by clamping and guiding the wooden cargo receiving material 32 located at the outermost position, these guide rollers 11a fix the posture of the lattice-shaped member and prevent it from shifting in position in the width direction, so that the lattice-shaped member is conveyed to the second clamping means in the correct posture and position.

[0041] More specifically, the guide section 11 in this embodiment is configured so that the guide rollers 11a arranged on the inside are movable in the width direction (a 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 adjusted appropriately depending on the width (thickness) of the wooden cargo receiving material 32 to be clamped and guided.

[0042] In addition, the second clamping means is provided in front of the second fixing means 2 described later, and is configured to position the grid member in a predetermined position in an appropriate state and maintain this positioning state so that the grid member does not shift position during the metal fitting installation work using the second fixing means 2.

[0043] As shown in Figure 5, the second fixing means 2 comprises a metal fittings storage section 3 that stores a stack of multiple flat metal fittings 33, a metal fittings transporting mechanism 4 that removes the metal fittings 33 stored in the metal fittings storage section 3 and transports them to a predetermined position, a second nailing section 5 that nails and fixes the metal fittings 33 transported by the metal fittings transporting 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) that supplies nails 34b to the second nailing section 5.As shown in the figure, these are arranged opposite each other 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.

[0044] 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, 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 toward 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 across the end face of the wooden leg material 31 and the side of the wooden load receiving material 32, as shown in Figures 7 to 9.

[0045] More specifically, the first metal fitting transport section 4a and the second metal fitting transport section 4b are configured to hold the metal fitting 33 by suction and adsorption, and the third metal fitting transport section 4c is configured to hold the metal fitting 33 by magnetic adsorption.

[0046] In detail, the first metal fitting conveying section 4a comprises 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, and the suction and adsorption section 12 is configured to be movable in the vertical direction, and 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 conveying section 4b by moving the moving section 13.

[0047] In addition, the second metal fitting conveying 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 this rotating section 16, and is configured to receive the metal fitting 33 from the first metal fitting conveying section 4a, rotate 90 degrees, and move the metal fitting 33 toward the third metal fitting conveying section 4c.

[0048] The third metal fitting transport section 4c is equipped with a moving section 19 having a magnetic attraction section 18 that holds the metal fittings 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 on its surface into which an ejection section that ejects the nails 34b of the second nail driving section 5 is inserted. The magnetic attraction section 18 is also movable forward and backward, and is configured to magnetically attract the metal fittings 33 held by the suction and adsorption section 15 of the second metal fitting transport section 4b when it moves forward, to receive the metal fittings 33 when the suction and adsorption section 15 is released from suction, and then move backward. After that, the moving section 19 moves downward to lower the metal fittings 33 to a predetermined position, and the magnetic attraction section 18 moves forward again to bring the metal fittings 33 into contact with the end face of the wooden leg 31 and the side of the wooden cargo receiving material 32 in a straddling state.

[0049] In this embodiment, as described above, the metal fittings 33 are magnetically attracted in the third metal fitting transport section 4c, and therefore the metal fittings 33 used are made of a magnetically attractable metal (for example, SUS430).

[0050] Furthermore, 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.Furthermore, by changing the layout of the transport section, the second metal fitting transport section 4b may be made unnecessary.

[0051] The second nailing unit 5 has four ejection units 5a that eject the nails 34b, and is configured to drive four nails 34b at the same time.

[0052] In addition, the second nail driving section 5 is configured to be movable in the forward and backward directions (configured to be able to move freely toward and away from the side of the lattice-shaped member), and is configured to move in conjunction with the forward and backward movement of the third metal fitting transport section 4c described above.

[0053] 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, and as shown in Figure 9, inserts the ejection unit 5a into the through hole 18a provided in the magnetic attraction unit 18 and presses the magnetic attraction unit 18, bringing the metal fitting 33 into close contact with the side of the lattice member, and then ejects and drives the nail 34b.

[0054] In addition, the number of nails 34b to be ejected from the second nailing section 5 can be changed as appropriate.

[0055] Next, a method for manufacturing the wooden receiving tray 30 using the wooden receiving tray manufacturing apparatus of this embodiment configured as described above will be described.

[0056] First, the worker selects product data corresponding to the wooden cargo receiving platform 30 to be produced from pre-registered product data in a control device (not shown) that controls the operation of the nailing device 7 and the metal fitting mounting device 9.

[0057] 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 leg materials 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.

[0058] When setting the wooden leg 31 on the wooden load-receiving material 32, the side with the groove 31a for looping the strap iron is set up. Also, the wooden leg 31 does not need to be set in an exact position perpendicular to the wooden load-receiving material 32, it is sufficient to set it roughly (because it will be set in the correct position by the first clamping means of the nailing device 7 after work begins).

[0059] The above-mentioned operation start operation activates the nailing device 7, and the first conveying means 6 transports the wooden cargo receiving material 32 and the first wooden leg 31 to the first clamping means. The first wooden leg 31 set on the wooden cargo receiving material 32 is positioned at a predetermined position so that it is perpendicular and the end face of the wooden leg 31 is flush with the side of the outer wooden cargo receiving material 32. While maintaining this first wooden leg 31 in the above-mentioned positioned position relative to the wooden cargo receiving material 32, the first fixing means 1 drives two nails 34a into each intersection where the first wooden leg 31 and the wooden cargo receiving material 32 intersect, thereby nailing the first wooden leg 31 and the wooden cargo receiving material 32 together.

[0060] 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.

[0061] Next, after the wooden leg material 31 and the wooden cargo receiving material 32 have been nailed and fixed together using this nailing device 7, the wooden leg material 31 and the wooden cargo receiving material 32 (lattice-shaped members) assembled in a lattice shape are sent to a metal fittings mounting device 9 connected to the nailing device 7, and in this metal fittings mounting device 9, metal fittings 33 are attached to the sides to reinforce the joint (connection) between the wooden leg material 31 and the wooden cargo receiving material 32.

[0062] Specifically, the wooden cargo receiving material 32 located at the outermost position on one widthwise side of the lattice-shaped member sent out from the nailing device 7 is clamped by the guide section 11 of the second conveying means 8 (clamped between the guide rollers 11a of the guide section 11), and is conveyed to the second fixing means 2 while maintaining the correct posture and position of the lattice-shaped member.

[0063] Next, the lattice-shaped member transported to the second fixing means 2 is positioned and fixed in a predetermined state by the second clamping means, and the second fixing means 2 attaches metal fittings 33 to a predetermined metal fitting attachment position, and the wooden leg material 31 and the wooden cargo receiving material 32 are connected and fixed by the metal fittings 33.

[0064] In detail, first, the first metal fitting transport section 4a operates, picks up one metal fitting 33 stored in the metal fitting storage section 3 by suction and moves it horizontally to the metal fitting transfer position with the second metal fitting transport section 4b.

[0065] Next, the second metal fitting conveying section 4b suctions and receives the metal fitting 33 held by the first metal fitting conveying section 4a, and by rotating the rotating section 16, flips the metal fitting 33 90° and places it on the side of the third metal fitting conveying section 4c.

[0066] Next, 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.

[0067] Next, the third metal fitting transport unit 4c holding the metal fitting 33 and the second nailing unit 5 move forward, and the metal fitting 33 held by the third metal fitting transport unit 4c is brought into contact with the side of the lattice member (abutting it in a straddling state between the end face of the wooden leg material 31 and the side of the wooden load-receiving material 32).After this metal fitting 33 abuts against the side of the lattice member, the second nailing unit 5 moves forward and presses the magnetic attraction unit 18 of the third metal fitting transport unit 4c holding the metal fitting 33, bringing the metal fitting 33 into close contact with the side of the lattice member.A nail 34b is then ejected from the second nailing unit 5 and driven in, thereby nailing and fixing the metal fitting 33 in place.

[0068] After the above work in the hardware mounting device 9 has been performed at the specified hardware mounting position, the work is completed and the completed wooden receiving platform 30 is sent onto a transport platform 40 connected to the hardware mounting device 9 and collected by a worker.

[0069] Regarding the recovery work of the completed wooden receiving platform 30, for example, a reversing device may be connected to the metal fitting attachment device 9, and the wooden receiving platform 30 may be automatically stacked and stored by this reversing device.

[0070] Since this embodiment is configured as described above, it becomes a wooden cargo tray manufacturing device that can efficiently manufacture durable wooden cargo trays 30 at low cost, and the wooden cargo tray 30 of this embodiment manufactured as described above using this wooden cargo tray manufacturing device becomes a durable wooden cargo tray 30 that has a simple configuration and can be manufactured at low cost.

[0071] The present invention is not limited to the present embodiment, and the specific configuration of each component can be designed as appropriate. [Explanation of symbols]
