The food supply device 7 is a device for supplying food to an empty tray pack a being weighed on the upper side surfaces 6b, 6b of the weighing support frames 6a, 6a of the weighing device 6, and includes a hopper 7a storing food and a hopper 7a. The food in 7a is weighed by the measuring support frame 6 of the measuring device 6.
It mainly comprises a food transport path 7b which is a path for transporting to an empty tray pack a on a, 6a.

The food conveying path 7b has a semicircular bottom surface, is closed on both left and right sides, and is open on the upper surface. Inside the food transport path 7b, a delivery screw blade shaft 7c is attached in the length direction thereof. A screw blade is spirally formed on the outer periphery of the screw blade 7c for delivery, and the screw blade 7c for delivery uses the spiral screw blade to convey food. The base end of the food transport path 7b is attached to the lower part of the hopper 7a, and the tip side of the food transport path 7b is the weighing support frames 6a, 6
a.

An open / close lid (not shown) is provided between the base end side of the food transport path 7b and the lower part of the hopper 7a. The open / close lid controls the supply of food from the hopper 7a to the food transport path 7b. ing. The opening / closing of the opening / closing lid is performed based on information on the weight measured by the measuring device 6. A food supply port 7d for supplying food to the lower tray pack a is formed on the bottom surface on the distal end side of the food transport path 7b.

Next, the operation based on the configuration of the above embodiment will be described below. First, the hopper 7 of the food supply device 7
Put a predetermined food into a. An empty tray pack a in which 100 to 150 pieces are stacked is placed on the inclined tray pack elevating table 2 of the tray pack supply device 1 and set. Since the inclined tray pack lift 2 is slightly inclined with respect to the horizontal, the stacked empty tray packs a to be placed on this
Is also set slightly inclined.

When the automatic driving switch is turned on,
The telescopic rod 3f of the lifting board 3e which suspends the suction transport board 3 located above the stacked empty tray packs a extends downward, and the suction transport board 3 connected to the lower end of the extending telescopic rod 3f. Descends, and the lower surface of the suction conveyance board 3 descends on the empty tray pack a in the uppermost stage.

In this case, the lower surface of the suction conveyance board 3 is horizontal, while the stacked empty tray packs a are inclined, and the uppermost tray pack a is also inclined. For this reason, the suction transport board 3 having a horizontal lower surface during descent is
First, a part of the upper end of the peripheral edge of the inclined uppermost tray pack a is hit.

When the horizontal lower surface of the lowering suction transport board 3 hits a part of the upper end of the peripheral edge of the uppermost tray pack a, the uppermost tray pack a and the number of the lower tray pack a are centered on the hit portion. In the tray pack a, a portion inclined downward is fan-shaped and spreads upward (see FIG. 6).
The uppermost tray pack a is easily separated from the separate tray pack a below it.

In the uppermost tray pack a, the portion inclined downward is rotated upward to be in a horizontal state, and is in close contact with the horizontal lower surface of the suction transport board 3. The suction transfer board 3 is operated by a suction pump (not shown).
The air is sucked out from an air suction hole 3g formed in the center of the lower surface of the.

For this reason, the uppermost tray pack a that is in close contact with the lower surface of the suction transport board 3 draws air from the space formed between the lower face of the suction transport board 3 and the inside of the tray pack a to generate a negative pressure state. As a result, while being sucked on the lower surface of the suction conveyance board 3, the entire tray pack a is slightly deformed to the inside where it is sucked (see FIG. 7), and further separated from the separate tray pack a thereunder. It becomes easy to do.

When the telescopic rod 3f extending downward starts to contract upward, the suction transfer board 3 connected to the lower end of the telescopic rod 3f rises. While only the uppermost tray pack a is deformed and adsorbed on the lower surface of the ascending suction transport board 3 (see FIG. 7), the tray pack a is closely lifted and separated from the lower tray pack a.

The suction transfer board 3 having only the uppermost tray pack a sucked on its lower surface rises as the telescopic rod 3f contracts. When the contraction of the telescopic rod 3f is completed, the reciprocating guide plate 3d to which the elevating plate 3e having the telescopic rod 3f provided below is attached is moved by the horizontal guide rod 3 of the horizontal reciprocating guide 3b.

When the reciprocating guide board 3d moves horizontally, the suction transfer board 3 connected to the reciprocation guide board 3d via the telescopic rod 3f and the elevating board 3e also moves horizontally as a unit, and is sucked on the lower surface of the suction transfer board 3. Tray pack a is transported.

When the reciprocating guide plate 3d, which moves in the horizontal direction, moves to the end and reaches above the start end of the conveyor 5 of the automatic tray pack weighing device 4, the telescopic rod 3f of the lift plate 3e again extends downward. The suction transport board 3 descends, and the tray pack a sucked on the lower surface of the suction transport board 3 descends on the start end of the conveyor 5.

In the suction transfer board 3, the suction operation from the air suction holes 3g is stopped, and a discharge pump (not shown) is operated to discharge air from the air discharge holes 3h, so that the suction transfer board 3 is in close contact with the lower surface of the suction transfer board 3. The pressure inside the tray pack a changes from a negative pressure state to a positive pressure state, and the tray pack a is easily separated from the lower surface of the suction transport board 3 and is placed on the endless belt 5c at the start end side of the conveyor 5.

Conveyor 5 of tray pack automatic weighing device 4
The suction transport board 3 with the empty tray pack a lowered thereon rises as the telescopic rod 3f that has extended downward contracts upward. When the reciprocating guide plate 3d of the lateral reciprocating guide 3b moves toward the inclined tray pack elevating platform 2, the suction transfer board 3 connected thereto also moves to return to above the inclined tray pack elevating platform 2, Hereinafter, the above-described operation is repeated to transport the empty tray packs a to the conveyor 5 of the tray pack automatic weighing device 4 one by one.

On the other hand, in the automatic tray pack weighing device 4 to which the empty tray pack a is conveyed and supplied by the tray pack supply device 1, the driving roller 5a of the conveyor 5 is driven by the motor 5i, and the driving roller 5a and the driven roller 5a are driven. The endless belt 5c wrapped around the endless belt 5b is circulated, and the empty tray pack a conveyed and supplied on the upper surface of the upper end of the endless belt 5c is conveyed toward the end.

The empty tray pack a has left and right upper side surfaces 6b,
6B, it is completely separated from the endless belt 5c of the conveyor 5 and is supported only by the weighing support frames 6a, 6a (see FIG. 8B). For this reason, the weighing device 6 of the weighing support frames 6a, 6a can reliably measure the empty tray pack a.

The empty tray pack a is inserted into the left and right measuring support frames 6.
When the sensor is placed on the upper side surfaces 6b and 6b of the sensors a and 6a, a sensor (not shown) detects this and temporarily stops the motor 5i driving the drive roller 5a. As a result, the transport operation of the conveyor 5 is stopped, and the weighing support frame 6 is stopped.
The empty tray pack a on the upper side surfaces 6b, 6b of the a, 6a is also stopped at that position.

The weighing device 6 with the empty tray pack a placed on the left and right weighing support frames 6a, 6a weighs the tray pack a and is tared, that is, the weight is reduced by the weight, and the scale is zero. Is set to

Subsequently, the food supply device 7 is operated, and the delivery screw blade shaft 7c in the food transport path 7b is rotated.
The screw blades rotate spirally, and feed the food discharged from the hopper 7a toward the tip end of the food transport path 7b. The food sent to the tip side is discharged downward from a supply port 7d formed on the bottom face on the tip side. Supply port 7d
An empty tray pack a is located below the tray, and the food discharged downward from the supply port 7d flows into the empty tray pack a.

In the measuring device 6 supporting the tray pack a,
When the weight of the food flowing into the tray pack a is measured and reaches a predetermined weight, the information is sent to the food supply device 7, and the opening / closing lid between the hopper 7a and the food transport path 7b is closed to supply the food. Is stopped, and the inflow of food into the tray pack a is stopped.

Thereafter, the motor 5i is driven again to operate the conveyor 5, and the tray pack a containing a predetermined weight of food is pushed by the pressing piece 5d attached to the circulating endless belt 5c, and is moved right and left. Measuring support frames 6a, 6
The upper side surface 6b of the endless belt 5c slides on the upper side surfaces 6b, 6b (see FIG. 8 (C)), and is again put on the upper surface of the endless belt 5c from the inclined surfaces 6c, 6c at the end portion, and is conveyed to the end side, and the discharge plate at the end 5j
To the next process.

The present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the spirit of the present invention. For example, in the above-described embodiment, the case where the bottom surface of the inclined type elevating guide 2a is provided slightly inclined from the horizontal and the lower surface of the suction conveyance board 3 is provided horizontally, but the present invention is not limited to this. In other words, the bottom of the inclined lifting guide 2a is horizontal,
The lower surface of the horizontal suction transport board 3 may be provided slightly inclined from the horizontal, or both may be provided slightly inclined. Further, in the above-described embodiment, the case where the separate air suction holes 3g and the air discharge holes 3h are provided on the lower surface of the suction transfer board 3 has been described.
One hole may serve as both the air suction hole 3g and the air discharge hole 3h. Further, the inclined tray pack elevating table 2 may be circulated up and down along the inclined elevating guide 2a. Further, the tray pack supply device 1 is of course not limited to the tray pack for food.

The lower surface of the suction transfer board being descended is lower than that of the uppermost tray pack by providing the bottom surface of the tray pack elevating table on which the stacked tray packs are mounted freely and the lower surface of the suction transfer board relatively inclined. When a part of the upper edge of the peripheral edge is hit, the uppermost tray pack and some of the tray packs beneath that point hit the lower part of the tray pack in a fan-shape toward the upper side. Thus, the uppermost tray pack can be easily separated from the separate tray pack thereunder. In addition, the air suction holes and the air discharge holes are provided on the lower surface of the suction and transfer board, and the uppermost tray pack is brought into close contact with the lower surface of the suction and transfer board to suck out air from the air suction holes. The uppermost tray pack that is in close contact with the lower surface, the air in the space formed inside the lower surface of the suction transport board and the tray pack is sucked out to be in a negative pressure state, and is suctioned to the lower surface of the suction transport board, Since the entire tray pack is slightly deformed inward to be sucked, the tray pack can be further easily separated from the separate tray pack thereunder. Therefore, only the uppermost tray pack can be reliably picked up and supplied independently of one another, regardless of the size of the tray pack.

According to a second aspect of the present invention, there is provided an automatic food supply apparatus for a tray pack, which has the advantages of the first aspect, is inexpensive, and has an individual tray supplied from the tray pack supply apparatus. A predetermined weight of food can be reliably supplied to the tray pack while weighing the pack with the tray pack automatic weighing device.
