In this state, as shown in FIG. 4D, when the elevating member 23 is moved rearward, the pallet 9 is pulled out to the loading / unloading unit 3b. By raising and lowering the elevating member 23 and changing the height of the engaging portion 25, the pallet 9 stored in the storage portion 3a at any stage can be pulled out.

板材搬送装置４は、移動支柱２２が前後移動用レール２１に沿って前後移動し、走行体１３が軌道１２に沿って走行し、板材保持具１４が昇降することで、板材保持具１４が、板材加工機１上で保持した製品板材Ｗを板材保管庫３の入出庫部３ｂに位置するパレット９上まで搬送する。比較的小さい製品板材Ｗの場合は１台の走行体１３により搬送し、大きな製品板材Ｗの場合は２台の走行体１３が協働して搬送する。   In the plate material conveying device 4, the movable column 22 moves back and forth along the rail 21 for longitudinal movement, the traveling body 13 travels along the track 12, and the plate material holder 14 moves up and down, so that the plate material holder 14 is The product plate material W held on the plate material processing machine 1 is conveyed onto the pallet 9 located in the loading / unloading unit 3b of the plate material storage 3. In the case of a relatively small product plate material W, it is transported by one traveling body 13, and in the case of a large product plate material W, two traveling bodies 13 are transported in cooperation.

製品板材Ｗが積載されたパレット９は、図８に示すように、係合部２５の前面部で係合ピン１１を前方に押すことにより、入出庫部３ｂから収納部３ａへ戻される。昇降部材２３を昇降させて係合部２５の高さを変更することにより、いずれの段についてもパレット９を入出庫部３ｂから収納部３ａへ戻すことができる。   As shown in FIG. 8, the pallet 9 on which the product plate W is loaded is returned from the loading / unloading unit 3 b to the storage unit 3 a by pushing the engagement pin 11 forward on the front surface of the engagement unit 25. By raising and lowering the lifting member 23 and changing the height of the engaging portion 25, the pallet 9 can be returned from the loading / unloading portion 3b to the storage portion 3a at any stage.

この板材搬送システム２は、板材搬送装置４の引出し方向移動部２０の動作により、板材保管庫３の収納部３ａと入出庫部３ｂ間のパレット９の引出しおよび戻しを行なうため、これらパレット９の引出しおよび戻しのための機構を別途設ける必要がなく、構成を簡素化できる。また、各段について収納部３ａと入出庫部３ｂ間のパレット９の引出しおよび戻しができるため、従来のようにエレベータ装置を設ける必要がなく、さらに構成を簡素化できる。しかも、パレット９の出し入れに際しては、パレット９を水平方向に移動させるだけでよく、エレベータ装置のように昇降が不要であるため、パレット９の出し入れの能率向上が図れる。   The plate material transport system 2 draws and returns the pallet 9 between the storage unit 3a and the loading / unloading unit 3b of the plate material storage 3 by the operation of the drawer direction moving unit 20 of the plate material transport device 4. There is no need to provide a separate mechanism for drawing and returning, and the configuration can be simplified. Moreover, since the pallet 9 can be pulled out and returned between the storage unit 3a and the loading / unloading unit 3b for each stage, there is no need to provide an elevator device as in the prior art, and the configuration can be simplified. In addition, when the pallet 9 is put in and out, it is only necessary to move the pallet 9 in the horizontal direction, and it is not necessary to move up and down like the elevator apparatus, so that the efficiency of putting in and out the pallet 9 can be improved.

上記実施形態では、引出し方向移動部２０の係合部２５を上下に移動させてパレット９の係合ピン１１と係合させるようにしているが、前記係合部２５を左右方向に移動させて前記係合ピン１１と係合させるようにしても良い。図９はその一例である実施形態の昇降部材を示す。この昇降部材２３の係合部２５は右側に開口する切欠き２５ｂを有し、この切欠き２５ｂに係合ピン１１が右方より進入自在とされている。切欠き２５ｂに係合ピン１１が進入すると、昇降部材２３とパレット９とがパレット引出し方向に係合した状態となる。切欠き２５ｂは、開口側ほど前後幅が広く形成されている。   In the above embodiment, the engaging portion 25 of the pull-out direction moving portion 20 is moved up and down to engage with the engaging pin 11 of the pallet 9, but the engaging portion 25 is moved in the left-right direction. You may make it engage with the said engaging pin 11. FIG. FIG. 9 shows an elevating member according to an embodiment as an example. The engaging portion 25 of the elevating member 23 has a notch 25b opened on the right side, and the engaging pin 11 can enter the notch 25b from the right side. When the engaging pin 11 enters the notch 25b, the elevating member 23 and the pallet 9 are engaged in the pallet drawing direction. The notch 25b is formed to have a wider front-rear width toward the opening side.

図９の実施形態の場合、図１０に示す動作を行う。まず、同図（Ａ）のように、係合部２５を係合ピン１１と同じ高さかつ左側に位置させ、同図（Ｂ）のように、係合部２５が係合ピン１１と前後同位置になるよう昇降部材２３を前方へ移動させる。次いで、同図（Ｃ）のように、昇降部材２３を右方に移動させて、係合部２５の切欠き２５ｂに係合ピン１１を進入させる。切欠き２５ｂは開口側ほど前後幅が広く形成されているため、切欠き２５ｂに係合ピン１１がスムーズに進入する。この状態で、同図（Ｄ）のように、昇降部材２５を後方へ移動させると、パレット９が入出庫部３ｂへ引き出される。   In the case of the embodiment of FIG. 9, the operation shown in FIG. 10 is performed. First, as shown in FIG. 3A, the engaging portion 25 is positioned at the same height and left side as the engaging pin 11, and the engaging portion 25 is moved forward and backward with the engaging pin 11 as shown in FIG. The elevating member 23 is moved forward so as to be in the same position. Next, as shown in FIG. 3C, the elevating member 23 is moved to the right, and the engaging pin 11 is inserted into the notch 25b of the engaging portion 25. Since the notch 25b is formed to have a wider front-rear width toward the opening side, the engagement pin 11 smoothly enters the notch 25b. In this state, as shown in FIG. 4D, when the elevating member 25 is moved rearward, the pallet 9 is pulled out to the loading / unloading unit 3b.

上記各実施形態は、引出し方向移動部２０の引出し方向の移動によってパレット９を収納部３ａから入出庫部３ｂへ引き出す引出し具が、パレット９側の部材である係合ピン１１にパレット引出し方向に係合する係合部２５とされているが、引出し具は、パレット９側の部材を把持する把持部としても良い（図示せず）。引出し具が係合部２５である場合および把持部である場合のいずれも、板材保管庫３の収納部３ａに収納されているパレット９を確実に引き出すことができる。   In each of the above-described embodiments, the pull-out tool that pulls the pallet 9 from the storage unit 3a to the loading / unloading unit 3b by the movement of the pull-out direction moving unit 20 in the pull-out direction is applied to the engaging pin 11 that is a member on the pallet 9 in the pallet pull-out direction. Although the engaging portion 25 is engaged, the drawing tool may be a gripping portion that grips a member on the pallet 9 side (not shown). The pallet 9 stored in the storage portion 3a of the plate material storage 3 can be reliably pulled out in both cases where the drawing tool is the engaging portion 25 and the gripping portion.
