The features of the techniques include: a #降台 that stacks a group of articles in which a plurality of articles are stacked, and a gripping member that transfers the aggregate of the uppermost layer of the raised article group to the four sides. The holding member has a vertical holding surface and is configured to advance and retreat horizontally with respect to the side of the assembly. However, the degree of deformation of the articles which are removed from the lower aggregate from the lower aggregate by the above-mentioned techniques causes the frictional resistance to be lowered, and the articles are dropped and difficult to hold. In contrast, the technique for solving the aforementioned problems is as shown in Patent Document 7. This technique is characterized in that the holding member is slightly inclined so that the lower portion of the gripping surface is closer to the assembly than the upper portion. Even if the frictional resistance is low and the article is biased downward, it is placed under the holding member, and deformation can be prevented without applying an additional pressing force. Drop and control. However, in the technique, since the tilting force of the holding member lowers the pressing force of the upper portion relative to the lower portion, as shown in Fig. 9, when the collective body is pressed, the central portion = the bucking force caused by the deformation of the article b is moved downward. ^ Gradually high, there is a possibility that the surface of the aggregate ~ will collapse. In the figure, _ holding member, B series item group. [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei.

'When the gripping member is used, the effect of the invention is as follows. According to the present invention, when the uppermost aggregate body is held by the four side faces, even if the article is deformed, the upper and lower sides are gradually raised, and the lowering of the article can be suppressed by the suppressing member. The face of the aggregate constitutes a non-disintegrating control that can remain stable. [Embodiment] In the present invention, the suppressing member is disposed on the upper surface of the aggregate - the position of the interval - the surface of the aggregate constitutes a range that does not collapse, allowing the article to be slightly increased upward, and the holding member can be opened. Force prevents significant deformation of the item. The interval between the restraining member and the upper surface of the aggregate is suitably "_, but may be appropriately changed depending on the size, strength, degree of deformation, etc. of the article. The suppressing member is disposed on the upper side of the aggregate by the suppressing member. After the weight is abutted = after the pulling mechanism is held at the position of the predetermined interval, even if the degree of the assembly is different for each grip, it can be kept at a position above the distance from the aggregate - a predetermined interval. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the invention are described in detail. 133247.doc 200938469 [Embodiment 1] The embodiment shown in Figs. 1 to 8 is an example in which a multi-layer cardboard box is divided into a layer-loading unloading device.

In the picture, 1 Unloading device, la frame, 2 series conveyor belt, 3 series lifting platform, 3a base, 4 series transfer device, 4a holding member, servant advance and retreat mechanism, 4c wheel, 5 series unloading belt, &; lifting platform, 6 series restraining member, 7 series pulling mechanism, 7a rack, 7b lifting cylinder, 7c tie, 7d pinion, 7e bracket, 7f locking cylinder, % Rod, 7h locking rack, 7i bracket, 7j bracket, 7k sliding guide, 7m hook, 7η brake, 7p stop, % frame, B series 'Ba The assembly 'b is an article, and the p is a machine plate. The unloading device 1 of the present embodiment includes the following members: a plurality of conveyance conveyors 2 that transport the group of articles B stacked on the pallet P as shown in FIG. The transporting and transporting belt 2 on which the article group B is placed is lifted and lowered between the pedestal 3a and the holding position of the collective body 3& and the uppermost aggregate Ba of the raised article group B is transferred by four sides. The transfer device 4' and the unloading conveyor belt 5 that unloads and transports the collected aggregate Ba at the transfer destination. The belt 5 can be lifted and lowered by the lifting platform 5a. The transfer device 4, as shown in Fig. 2, includes a four-piece holding member 牝 133 247.doc 200938469, which is surrounded by the front, rear, left and right, and includes a wheel frame u The upper traveling line moves to the transfer position. The angle e of the four holding members ^ is as shown in Fig. 3, and the lower portion thereof is inclined more than the upper portion respectively. To further: a (the drawing is slightly exaggerated). The suppressing member 6 is on the transfer device 4 4 pieces can be lowered by their own weight. β 4 ❹ 引 In the pulling mechanism 7, 'the rack 7a is attached to the upper part of the restraining member 6 as shown in Figs. 4 to 6, and the hook 7m is formed at the front end. Mounted on the upper part of the rack, the lower part of the rod 7c of the cylinder 7b passes through the notch of the hook 7m, and the rod has a stopper plate 7P which can be locked with the hook-down, and the rack can be freely lifted and lowered from the gear. The bracket 7e is pivotally supported by the pinion 7d mounted on the cylinder for locking, and is freely movable up and down. The lower end of the bracket is provided with a locking rack which can be spouted with the lower portion of the pinion 7d. The lifting cylinder 7b is a member that reduces the deceleration by the weight of the restraining member itself. The holder holds the member of the pinion 7d at the lower limit position. The slide rail 7k included in the guide bracket is a member for restraining the restraining member from the frame 7q when the brake-based restraining member 6 included in the lower surface of the member i7m that supports the rack 7a without being disturbed by the pinion 7 is lowered. The member of the lower limit position of 6. In the present embodiment, as shown in Fig. 7 (4), the extension lock cylinder 7f separates the lock gear from the pinion 7d so that the restraining member 6 is lowered to the lower limit position by its own weight (the pinion 7d is driven). The restraining member 6 is lifted by the cylinder 7b! Fit down. As shown in Fig. 7 (b), the upper side of the assembly Ba of the uppermost layer of the transporting cassette 2 on which the article group b is placed is brought into contact with the restraining member 6, and the fishing wheel 7 is included in the #轮轮7& The arm is lifted up by the steam cylinder %. The restraining member 6 is raised (the pinion 7 (1 driven), and the uppermost stack is raised 133247.doc 200938469. When the position is held, the lifting platform 3 is stopped. T shows that the retracting lock cylinder 7f closes the lock teeth (four) gears (four). In this state, the tooth center is locked by the small wheels 7d. As shown in Fig. 7(d), the lock is not further retracted, and _ two = : A gap of 5 mm is formed between the upper sides. The height of each holding is different by coughing. Even if the collecting body is separated from the human body, the restraining member 6 can always maintain a certain distance from the upper surface of the aggregate Ba. As shown in Fig. 8, the holding member 4 holds the set member 4, and the article b of the center portion is tilted by the grip member h to suppress the lower portion. However, the upper member is abutted against the upper restraining member 6 'The surface constitutes a shot that does not collapse and remains stable. The second door: the gap between the member 6 and the upper surface of the aggregate η, The pressing force of the holding member 4a prevents the article b from being significantly deformed. Loading L: The table 3 is slightly lowered and separated from the lower layer assembly, and then moved = the transfer position is moved, and the unloading and transporting belt 5 is lifted by the lifting platform 5a, liberating The gripping member 4 is assembled to be placed on the unloading transport I, the transport belt 5 is lowered to the position before the ascent, the aggregate-sending rack 2 is set back to the original position, and the extension lock cylinder 7f is locked to the lower limit. 4帛The pinion gear is separated, and the restraining member 6 is lowered by its own weight and stands upright for raising the next aggregate Ba.
