Nau. This will be described with reference to the manufacturing process diagram of the side plates 1 and 2 shown in FIG. First, as shown in FIG. 1A, the primary processing is performed in the primary processing machine 10. As shown in FIG. 2, one sheet of resin raw material M is placed on the loading table 11 a of the base 11 and is transported by the transport rollers 12 of the transport mechanism 13. In this process, as shown in FIG. 6, the side wall blade 21 and the bottom surface blade 22 of the fitting groove forming mechanism 20 correspond to the three plate materials Sa on the lower side (the surface side of the plate material Sa) of the resin raw material plate material M. Thus, the fitting groove 5 is formed along the longitudinal direction of the one edge of the plate material Sa.

Sa is discharged by the transport roller 12. In this case, the fitting groove 5 and the V groove 9 are formed substantially at the same time. Therefore, as in the conventional case, when machining each groove 5, 9 by using an individual machine or by using one machine, Since it is not necessary to change the set of tools one by one, the man-hours for processing are reduced and the manufacturing efficiency is improved.

Next, as shown in FIG. 1C, the secondary processing is performed in the secondary processing machine 30. First, a large number of side plate intermediate materials Sb are arranged in a row on the table 32 (for example, 40 sheets). In this case, the side plate intermediate material Sb is manufactured in advance as shown in FIG. 1B, or is manufactured one by one when mounted on the table 32 and mounted. The side plate intermediate member Sb is manufactured by manually bending the plate member Sa along the V groove 9 and joining the back surfaces to each other. As shown in FIG. 10, if a large number of side plate intermediate members Sb are placed on the table 32, the air cylinder 39 of the holding mechanism 38 is driven to hold and hold the plurality of side plate intermediate members Sb from the front and rear directions. . Further, the plurality of presser bars 36 are rotated to press the plurality of side plate intermediate members Sb from above, and are locked by the lock portion 37.

In this state, the start button 49 is pushed. As a result, the air cylinder 35 is driven and the table 32 is moved forward. In the forward movement process of the table 32, as shown in FIGS. 10 and 11, the motor 48a of the split cutter mechanism 40 and the notch forming mechanism 42 is driven to drive the cutting cutter 41 and the notch through the rotary shaft 46.

The penetrating portion 33 and the presser bar 36 are penetrated to advance. As a result, the side plate intermediate material Sb is cut corresponding to the predetermined lengths of the pair of first side plates 1 and the pair of second side plates 2, and at the same time, the side plate intermediate members Sb corresponding to the side plates 1 and 2 are cut at the same time. A full cut 3 and a second cut 4 are formed.

When the cutting and the notch formation are completed, the rocking bodies 45 of the cutter support portions 44 provided on the upper side and the lower side respectively by the air cylinder 47 are operated in synchronization, and the cutting cutter 41 and the notch cutter 43 are moved. The table 32 is withdrawn from between the penetrating portion 33 and the holding bar 36. Further, the table 32 is moved backward by the air cylinder 35. Further, the motor 48a is stopped and the rotations of the cutting cutter 41 and the cutting cutter 43 are stopped via the rotary shaft 46. Then, when the table 32 is located at the original position, the air cylinder 39 of the pressing mechanism 38 is driven to release the holding of the multiple side plate intermediate members Sb, and the lock portion 37 is released to release the pressing bar 36. Is rotated and lifted to release the pressing of the side plate intermediate member Sb. This completes the manufacturing of the side plates 1 and 2.

In this case, in the past, the side plates 1 and 2 were manufactured one by one, but since the side plates 1 and 2 are collectively formed, the manufacturing efficiency is improved, and mass production Will be possible. Further, in the past, the machining of the cuts 3 and 4 for the side plates 1 and 2 was performed by using individual machines, or when one machine was used, the tools were changed one by one. Almost at the same time, the notches 3 and 4 are formed corresponding to the side plates 1 and 2, so that the processing man-hours are reduced and the manufacturing efficiency is improved.

Then, the product on the table 32 is taken out and packed, and the next step is transferred. In this case, since the pair of first side plates 1 and the pair of second side plates 2 related to the combination per one box are continuously processed together, it is easy to combine them, quantity control is easily performed, and packing and transportation are performed. It will be easier. Further, when assembling the box in the next step, the side plates 1 and 2 per box are continuously aligned, so that the assembling is facilitated and the handling is extremely easy.

[Effect of the invention]

 As described above, according to the box side plate manufacturing apparatus of the present invention, the raw material plate material is cut into a predetermined width by the primary processing machine, and the fitting groove and the V groove are formed in the raw material plate material substantially at the same time. Since it is made into a plate material, each groove is processed using an individual machine as in the past, or when one machine is used, it is compared with the case where the tools are changed one by one. In addition, the number of processing steps can be reduced, and thus the manufacturing efficiency can be significantly improved.

Further, since a large number of side plate intermediate materials can be collectively processed by the secondary processing machine, the manufacturing efficiency is significantly improved as compared with the conventional case where each side plate intermediate material is manufactured individually. Be ready for production. Further, a pair of first side plates and a pair of second side plates are cut with respect to the side plate intermediate member so as to correspond to predetermined lengths, and notches are formed substantially at the same time. Since one side plate and a pair of second side plates are formed, it is necessary to use individual machines for the cutting process for each side plate as in the past, or to change the tools one by one when using one machine. Compared with the case of performing the above-mentioned method, the number of processing steps can be reduced, and therefore the manufacturing efficiency can be significantly improved.
