Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig used for fixing a work to be mounted on a wood-spinning lathe when cutting a cylindrical or columnar wooden product. The present invention relates to a method for manufacturing a wooden barrel container using a tool.

[0002]

2. Description of the Related Art Wood products are inferior to resin products and metal products in terms of durability and corrosion resistance. However, the texture and texture of the wood gives warmth to the user, and thus is in tandem with nature in recent years. Is being re-evaluated. As an example, traditional barrel containers are offered as piggy banks or storage boxes,
It is raising new demand.

[0003] In a traditional barrel container, a plurality of pieces of wood having a cross section curved in an arc shape are joined into a cylindrical shape, and one or both openings are closed with a plate-like material, and a ring is provided near both openings. Each piece of wood is required to have a certain degree of dimensional accuracy because it is formed with the shape of a "haga". In particular, in the case of a barrel container whose peripheral surface is bulged outward, such as a container for sake, a piece of wood bent in a long direction is used. Was one of the causes.

Therefore, a new technique has been proposed in order to make the production simple and inexpensive while utilizing the appearance design of the wooden barrel container. For example, utility model registration No. 3033846
No. “Wooden barrel-shaped accessory container” uses a piece of wood of almost constant thickness, and grinds the outer surface to make an upright cylindrical surface, but the outer surface protrudes outward. Various barrel containers have been proposed.

[0005]

However, in the barrel container according to the registered utility model, since the outer peripheral surface needs to be ground, each piece of wood must be firmly adhered using an adhesive. However, it was merely decoratively fitted to enhance the design value of the wooden barrel. However, for example, while removing the hoops, the seam between the pieces of wood is released and the pieces are broken apart, while the pieces of wood are seamed again, and if they are fitted together, a prefabricated barrel container that becomes the original barrel container is used. If provided, it would meet the demands of the craftsman of the consumer and stimulate new demand, but for that purpose, they had to give up decorative cutting on the outer peripheral surface.

Therefore, in the present invention, in order to provide a simple and inexpensive wooden barrel container which is capable of being freely assembled and disassembled and subjected to decorative cutting on the outer peripheral surface to further enhance the design value, it is necessary to provide a potter's wheel. It is an object of the present invention to provide a dedicated jig to be mounted on a machine. It is another object of the present invention to provide a method of manufacturing a wooden barrel container using the dedicated jig.

[0007]

According to the present invention, in order to solve the above-mentioned problem, first, the present invention is applied to a woodworking lathe capable of holding a workpiece by a spindle and a tool rest.
As a pair of dedicated jigs, when the jig main body was mounted on the main spindle and the tool rest, a plurality of sharp support pins were formed on the opposing surfaces of each jig main body.

In a woodworking lathe having a main shaft rotated by a power source such as a motor and a tool rest which is disposed opposite to the main shaft and moves back and forth, when jig bodies are respectively mounted on the main spindle side and the tool rest side, By making the support pins on the jig body bite into the front and back sides of the workpiece,
The workpiece can be held between the two jig bodies. When the workpiece is a cylindrical wooden barrel container formed by joining curved pieces of wood, the support pins are cut into each piece of wood, so that each piece of wood is not bonded and fixed, and Thus, even when the workpiece is removed, the uneven pattern can be cut on the outer peripheral surface of the workpiece while preventing the workpiece from falling apart.

[0009] When the support pin bites into the workpiece, hole-shaped scratches are formed on the front and rear surfaces of the workpiece. These scratches are finished by cutting the front and rear faces of the workpiece (small edge in the case of a barrel container). If it is, it can be finished neatly without leaving any trace.

In the invention described in claim 2, in the jig, the position of the support pin can be changed on the jig body according to the diameter of the workpiece. By changing the mounting position of the support pin, it was configured to be able to cope with workpieces of various diameters.

Further, in the invention described in claim 3, in the jig for the woodworking lathe, an attachment can be attached to the jig main body. That is, when the workpiece is a cylindrical object, an attachment having a different outer diameter corresponding to the inner diameter of the cylindrical object and being detachably exchangeable with respect to the surface on the support pin mounting side is provided. . If this attachment is attached, when the cylindrical workpiece is rotated by the main shaft and the cutting tool is brought into contact with the outer peripheral surface of the workpiece and cutting is performed, the pressing force of the blade may be too strong. However, it is possible to prevent the workpiece from dropping off the support pins.

Furthermore, in the invention described in claim 4, a wooden barrel container is manufactured by the following procedure by using the jig for a woodworking wheeler. That is, (1) a step of joining a plurality of pieces of wood whose cross section is curved in an arc shape and temporarily fixing the pieces with a sword to form a cylindrical barrel body, and (2) combining the barrel body with a pair of woodwork. After holding the jig for the potter's wheel jig, remove the hoop. (3) After rotating the barrel container body, apply an arbitrary uneven pattern on the outer peripheral surface with a cutting blade, Removing from the tool,
(4) Replace the jig on the spindle side with the chuck for exclusive use for forging, and replace the jig on the turret with the tool, and fix the barrel container body to the spindle so that the edge located on the turret is exposed. And (5) a step of cutting the fore edge with a cutting blade while rotating the barrel container body, and (6) a step of subsequently cutting the other fore edge, a disk-shaped bottom plate and a lid plate This is a method for manufacturing a wooden barrel container in which is formed so as to be fittable.

[0013] Generally, when an uneven pattern is cut on the outer peripheral surface of a barrel container body in which a plurality of curved pieces of wood are joined together, the presence of a hoop becomes an obstacle. If the hoop is removed, the barrel container body will fall apart, so that in order to freely cut the outer peripheral surface, it has been conventionally necessary to firmly join each piece of wood with an adhesive. However, if the jig according to the present invention is used, it is possible to freely cut the outer peripheral surface of each piece of wood without adhering each piece of wood, and it is possible to increase the width of creation.

While the barrel container body Y is being rotated, the fore-edge cutting is performed (FIG. 17), and then the opposite fore-edge is similarly cut, thus completing all the cutting operations. The completed barrel container body Y is provided with linear grooves 41
And a disc-shaped top plate and a bottom plate are formed so as to be fittable (FIG. 18).

FIGS. 19 to 26 show the procedure for assembling the barrel-type storage box manufactured using the jig according to the present invention. Each piece of curved wood that constitutes the bank box body has a slightly different shape, so as shown in the figure, when manufactured with a woodworking lathe, engraved numbers etc. on the back side in advance and order the combination Should be clarified.

First, the wooden pieces 4 are spliced in the order of the numbers on the palm (FIG. 19). When about three pieces have been spliced, the top plate 5 and the bottom plate 6 are fitted into the linear grooves 41 (FIG. 20). The slit through hole 51 formed in the center of the top plate 5 is a slot for coins or the like. Further, the pieces of wood 4 are joined in order (FIG. 21),
When one piece of wood 4 is left, the main body of the saving box is erected and the last piece of wood is spliced (FIG. 22).

Next, the upper side is wound with T (FIG. 23). At this time, make sure that the pieces of spliced wood do not fall apart.
It is good to temporarily fix with rubber band W. After firmly screwing both ends of T on the upper side (FIG. 24), wrap the T on the lower side in the same manner and screw it tightly (FIG. 25). Finally, the rubber band used for the temporary fixing is removed to complete the savings box (FIG. 26). The coin box thus completed not only can take out coins and the like without breaking the coin box by unscrewing the T, but also can enjoy the process of assembling and disassembling like a craft.
