Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates mainly to a device for automatically supplying trays for packing fruits one by one, and to a separating tool used for supplying trays stably without any trouble. It is useful in.

[0002]

[Prior art]

 Fruits such as apples, pears, peaches, and tomatoes are shipped in trays that have many recesses for storing these fruits. In the past, fruit was stored in trays manually, but in recent years automatic introduction machines have been introduced along with the consolidation of co-selection sites. The automatic contest machine transports a large number of stacked trays one by one from the uppermost tray into the cardboard box while sucking them with the suction arm, and then sucking the fruits with the suction arm, and putting the fruits in the recesses of the tray. Is to be stored.

[0003] In the case of transporting trays one by one in such an apparatus, since a concave portion for storing fruit is formed in the tray, the second tray is transported when the uppermost tray is sucked and transported. May move accompanying the top tray. The next time the uppermost tray is transported by suction, the position of the uppermost tray is shifted and deviated from its normal position. Automatic operation must be stopped because it is not properly stored in the ball.

[0004] Therefore, there is a need for a separating tool for preventing the second tray from moving during suction conveyance of the uppermost tray. Conventionally, as a release tool, as shown in FIG. 7, a number of slits 52 are provided on one side of a soft synthetic resin sheet 51, and locking pieces 53 are formed between the slits. And an auxiliary piece 54 is provided below the sheet 51 to contact the side edge of the second tray.

[0005]

[Problems to be solved by the invention]

 In the above-mentioned conventional loosening tool, since the locking pieces 53 are formed by the slits 52, the adjacent locking pieces are close to each other. As a result, the second tray cannot be quickly pressed when the top tray is moved, and the purpose of preventing the movement of the second tray may not be sufficiently achieved. Therefore, the auxiliary piece 54 is provided, but the auxiliary piece 51 only comes into contact with the second tray, so that the movement inhibiting effect is insufficient.

[0006]

[Means for Solving the Problems]

 This invention is based on a device for stacking a large number of packaging trays, which is attached to a tray supply device in which the uppermost tray is sequentially conveyed by a suction arm, and which holds a side edge of the tray. A large number of locking pieces to be locked to the edge are formed in a chevron shape, and the tray is moved so that the locking with the uppermost tray is released so as to constitute a separating tool of the tray supply device. It is preferable that the protruding length of the locking piece is sequentially increased from the front side to the rear side of the tray (Claim 2), and the rigidity of the tip of the locking piece is from the front side to the rear side. It is preferable to weaken sequentially (claim 3). The shape of the locking piece is preferably a triangular plane (claim 4).

[0007]

[Action]

 In the present invention, the locking pieces are mountain-shaped, so that the locking pieces are highly independent. Therefore, as the uppermost tray moves, the lock with the tray is released sequentially from the front locking piece. The unlocking is performed by the elastic deformation of the locking pieces and the elastic deformation of the tray (mainly a molded product of a foamed synthetic resin sheet). When the length of the locking piece is gradually increased from the front side to the rear side of the tray as in the invention of claim 2, the front locking piece has a small margin for locking with the tray and is relatively easily locked. Is released and the second tray is held down to prevent the front part from being lifted up, and the rear locking piece has a large locking allowance and securely holds down the second tray. Prevent tray movement. When the rigidity of the front end of the locking piece is increased, the locking with the uppermost tray is released, and then the locking piece is locked to the second tray instantly. Therefore, the second tray does not move accompanying the uppermost tray. In addition, if the rigidity of the tip portion of the locking piece on the rear side is reduced, the locking piece having a large locking margin is released without difficulty as the tray moves.

[0008]

[Embodiment of the invention]

 In FIG. 1, a large number of trays 2 are stacked on a tray loading table 1 of a tray supply device, and a suction arm 3 is disposed above a top tray 2a. The tray mounting table 1 gradually rises as the stacked trays are conveyed and the height of the stacked trays decreases. The suction arm 3 moves in the up-down direction and the front-rear direction, and sucks and conveys the uppermost tray 2a. Here, a separating tool 4 that is engaged with the side edge of the uppermost tray 2a is attached to the mounting portion 5 of the supply device so as to face both side edges of the uppermost tray 2a.

The separating tool 4 has a configuration shown in FIGS. 2 and 3. That is, a large number of triangular locking pieces 7 projecting continuously from one side of an elastic synthetic resin plate 6, and the locking pieces 7 project from the front side of the tray 2 in use. Are small and are gradually increased toward the rear side of the tray 2. Further, the side surface shape of the locking piece 7 is such that the front end is relatively thick at the front end and the rigidity of the front end is strong, and the front end is thinner at the rear end. The rigidity of the tip is weakened. In the figure, reference numeral 8 denotes a long hole for attachment.

The separating tool 4 shown in this embodiment is used by fixing it to a mounting portion 5 of a supply device with a screw. At this time, the positioning is performed so that the base of the locking piece 7 is aligned with the side edge 9 of the tray 2. Here, since the locking pieces 7 of the loosening tool 4 are sequentially elongated from the front side to the rear side of the tray 2, the locking depth of the locking pieces 7 with the tray side edge is equal to the front side of the tray. Then shallow, deep on the rear side.

FIG. 4 shows an example in which the protruding lengths of the locking pieces 7 are all the same, and other structures are the same as those in FIGS. 2 and 3. The loosening tool 4 of this form is installed slightly inclined with respect to the side edge 9 of the tray 2, and the locking piece 7 on the front side of the tray has a small locking depth with the tray 2, and the engaging piece 7 on the rear side of the tray 2 It is preferable that the stop piece 7 be engaged with the tray 2 so that the locking depth is large.

FIG. 5 shows a plan view of the locking piece 7 having a circular arc shape. As in the embodiment shown in FIGS. 2 and 3, the locking piece on the front side of the tray 2 has a small protrusion length. The rear locking piece has a large protruding length.

When the suction tool 3 shown in each of the above embodiments is attached to the supply device and the suction arm 3 is operated, the uppermost tray 2 a sucked by the suction arm 3 initially has both side edges 9 at the separation section. 4 are pressed by the locking pieces 7. At this point, the uppermost tray 2a is sucked by the operation of the suction arm 3, and its front moves upward and then moves forward. At this time, as the front portion of the tray 2a moves upward, the front locking piece 7a of the loosening tool 4 is unlocked from the tray 2a, and is locked to the side edge of the second tray 2b. . In particular, since the locking piece on the front side has a small locking depth, the locking is released by a slight movement of the tray 2a, and quickly presses the second tray 2b. Moreover, since the front locking piece is thick to the tip and relatively rigid, even if the locking depth is small, the second tray that has been lifted up along with the uppermost tray can be securely used. Can be held down. Therefore, the second tray 2b is prevented from floating along with the uppermost tray 2a. Thereafter, with the movement of the uppermost tray 2a, the locking portion 7b at the intermediate portion or the rear is also released from being locked with the uppermost tray 2a, and presses the second tray 2b. Here, since the rear locking piece 7b has a deep locking depth with the tray, the lifting of the second tray 2b is reliably prevented. In addition, since the rear locking piece has a thin tip portion, the rigidity is weak and the elasticity is rich, so that even if the locking depth is deep, the locking state is smoothly released by the movement of the tray 2a. Therefore, only the uppermost tray 2a is conveyed, the second tray 2b does not rise and move, and the position of the second tray does not shift as shown by the chain line in FIG.

In the above description, the locking depth between the locking piece 7 of the loosening tool 4 and the tray 2 is shallow in the front and deep in the rear, but as shown in FIG. Even if a loosening tool with the same protrusion length is provided so that the locking depth is the same in the front and rear, the second piece can be obtained by appropriately selecting the locking depth and elasticity of the locking piece. The tray can be reliably held down and its movement can be prevented.

[0005]

[Effect of the invention]

 According to this invention, since the loosening tool is formed by projecting a large number of mountain-shaped locking pieces that lock to the side edge of the tray, the independence of the locking pieces is extremely high as compared with the conventional loosening tool. Therefore, the slightest movement of the uppermost tray unlocks the front locking piece and locks it to the second tray, so that the lifting of the second tray can be suppressed early. Can be. Then, when the uppermost tray further moves, the lock with the rear locking piece is released, the second tray is securely pressed, and the movement is prevented before it occurs. Therefore, the second tray does not move accompanying the movement of the uppermost tray, so that a transport trouble due to the displacement of the tray can be eliminated.
