DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scoop-up type depanner which scoops up products such as confectionery, bread and the like from a top plate and carries them out of the top plate.

[0002]

2. Description of the Related Art In a bread factory or the like, products such as confectionery and bread are baked while moving a top plate on a conveyor, and the baked products are carried out of an oven together with the top plate by a conveyor. An apparatus called a depanner is used to remove the baked product from the top plate. A type using a flat conveyor has been developed as a kind of the depanner. In this flat conveyor, the top plate side edge is extremely thinly finished, and the top plate side edge is placed at a height almost in contact with the top plate. Then, when the product moving along with the top plate by the conveyor reaches the top plate side edge, the top plate side edge peels off the product and the top plate, and the peeled product is flattened from the top plate side edge. It is placed on a conveyor and transported to the other end. A rising piece is usually formed on the periphery of the top plate. Therefore, it is necessary to prevent the rising piece from being caught on the flat conveyor when the top plate is moved. For this reason, the flat conveyor is generally capable of swinging about the edge on the side opposite to the top, between a scooping position where the edge on the top is almost in contact with the top and an avoidance position where the rising piece is avoided. .

[0003]

When the flat conveyor is at the scooping position, it is preferable that the angle between the top plate and the flat conveyor is small. For this reason, the top board usually moves slightly diagonally downward, and the flat conveyor lifts the product slightly diagonally upward. At this time, the product cannot be properly placed on the flat conveyor, and a phenomenon in which the product behaves unstablely between the top plate and the flat conveyor is likely to occur. When the flat conveyor swings to the avoidance position in order to avoid the rising piece of the top plate, the product often falls from the flat conveyor and falls to the floor as it is. The present invention prevents such a phenomenon from occurring.

[0004]

In order to solve the above-mentioned problems, according to the present invention, there is provided a flat conveyor which picks up a product on a top plate conveyed by a conveyor at an edge on a top plate side and conveys the product to the other end; A product drop prevention body that moves above the side edge, and a depanner with a product drop prevention mechanism mainly including a controller, wherein the flat conveyor has the top plate side edge around the other end side. It is swingable between a scooping position almost in contact with the top plate and an avoidance position for avoiding a rising piece formed on the periphery of the top plate, and from the top plate side edge toward the other end side. The product fall prevention body is inclined upward, and the product fall prevention body is positioned between a passage position forming a gap between the top plate side edge and the product allowing passage of the product and a drop prevention position almost closing the gap. The controller is movable, and the controller Immediately after the rising piece on the front side in the moving direction has passed the top plate side edge, the flat conveyor is swung from the avoidance position to the scooping position, and the product drop prevention body is moved from the drop prevention position to the passing position. Move,
And, when the rising piece on the rear side in the moving direction of the top board approaches the top side edge, the flat conveyor is swung from the scooping position to the avoidance position and passes through the product drop prevention body. We have created a depanner with a product drop prevention mechanism that moves from a position to a drop prevention position.

[0005]

According to the depanner of the above construction, a product fall prevention member is added on the top plate side edge of the flat conveyor, and the controller swings the flat conveyor from the scooping position to the avoidance position and prevents the product from falling. The body is moved from the passing position to the fall prevention position where the gap allowing the product to pass between the top plate side edge and the top plate side edge is substantially closed to prohibit the product from passing. In other words, when the flat conveyor swings to the avoidance position and there is a risk of the product falling, the product fall prevention member is located at the above-mentioned fall prevention position, so that the product fall can be substantially eliminated.

Is automatically scooped and removed from the top plate 10. The depanner 1 with a product drop prevention mechanism of this example is shown in FIG.
, A flat conveyor 2, a product fall prevention body 3 that rotates above the top plate side edge 2 </ b> A of the flat conveyor 2,
The controller 4 is mainly used. The controller 4 has a photoelectric sensor 5, a timer 6 connected to the photoelectric sensor 5, a motor 7 for rotating a product drop prevention member, and a motor 8 for swinging a flat conveyor.
Reference numeral denotes a forward / reverse rotation motor with a speed reducer, which is connected to the timer 6.

The flat conveyor 2 has a belt feed motor (not shown), pulleys 12, 12, and a top plate side edge 2.
It is installed inclining upward from A to the other end 2B. Then, centering on the other end 2B, the top plate side edge 2A swings between a scooping position almost in contact with the top plate 10 and an avoidance position avoiding the rising piece 10B formed on the periphery of the top plate. It is possible. The oscillating power is supplied by a flat conveyor oscillating motor 8. The top plate side edge 2A of the flat conveyor 2 is so thin that it can enter between the confectionery bread 11 and the bottom surface of the top plate 10. The flat conveyor 2 picks up the confectionery bread 11 on the top plate 10 carried by the chain conveyor 9 at the top plate side edge 2A and carries it to the other end 2B.

The product drop prevention member 3 is a rectangular metal plate, and is fixed to a shaft 15 by a pressing member 13 and a bolt 14 on one side of a long side thereof as shown in FIG. The long side of the product fall prevention body 3 is substantially the same as the width of the flat conveyor 2, and the short side is designed to be longer than the height of the confectionery bread 11 to be conveyed. Shaft 15
The rod end bearings 16, 16 supporting both ends of the flat conveyor 2 are erected on the left and right sides of the top plate side edge 2A of the flat conveyor 2, respectively.
As shown in FIG. 1 above the top plate A,
A is rotatably supported between a passage position where a gap allowing passage of the confectionery bread 11 is formed between the position A and a fall prevention position where the gap is substantially closed. The power for this rotation is supplied by a product drop prevention body rotation motor 7.

The photoelectric sensor 5 is installed above the chain conveyor 9 at a certain distance from the flat conveyor 2,
The presence of the top 10 is detected, and a presence signal corresponding to the presence is output. The fixed distance from the time when the presence signal of the top 10 is input to the timer 6 from the photoelectric sensor 5
At the time when the time required for the movement of the product has elapsed, the timer 6 energizes the product drop prevention body rotating motor 7 and the flat conveyor swinging motor 8. As a result, the controller 4 swings the flat conveyor 2 from the avoidance position to the scooping position immediately after the rising piece 10A on the front side in the moving direction of the top 10 detected by the photoelectric sensor 5 has passed the top side edge 2A. At the same time, the product fall prevention body 3 is rotated from the fall prevention position to the passing position. And the photoelectric sensor 5
From the time when the time required for the top 10 to move the predetermined distance from the time when a signal is input to the timer 6 from the time elapses, the top 10 further moves a distance corresponding to the entire length of the top 10 in the moving direction of the top 10 When the time required for the operation has elapsed, the timer 6 energizes the product drop prevention member rotating motor 7 and the flat conveyor swinging motor 8. As a result, the controller 4 operates the rising piece 1 on the rear side in the moving direction of the top 10.
When 0B approaches the top plate side edge 2A, the flat conveyor 2 is swung from the scooping position to the avoidance position, and the product fall prevention body 3 is rotated from the passing position to the fall prevention position.

Next, the operating state of the depanner 1 of this embodiment will be described with reference to FIGS. When the top 10 conveyed by the chain conveyor 9 moves to the photoelectric sensor 5 installed a predetermined distance before the flat conveyor 2, the photoelectric sensor 5 inputs a presence signal of the top 10 to the timer 6. After the signal is input, the timer 6 energizes the product drop prevention member rotating motor 7 and the flat conveyor swinging motor 8 at a point in time after the time required for the top plate 10 to move the predetermined distance. The time after the signal input from the photoelectric sensor 5 and the time after the time required for the top 10 to move the fixed distance is referred to as the top 1 whose presence is detected by the photoelectric sensor 5.
This is the time when the rising piece 10A on the front side in the movement direction of 0 just passes through the top plate side edge 2A. Therefore, as shown in FIG. 2A, the controller 4 controls the product drop prevention member rotating motor 7 and the flat conveyor swinging motor 8 at the above-mentioned time from the timer 6 to supply electric current to the front side of the top plate 10 in the moving direction. Immediately after the rising piece 10A passes the top plate side edge 2A, the flat conveyor 2 is swung from the avoidance position to the scooping position, and at the same time, the product drop prevention body 3 is rotated from the drop prevention position to the passing position. Product drop prevention body 3 at this passing position
Is a position above the flat conveyor 2 and substantially parallel to the flat conveyor 2 at the scooping position. After this, FIG.
As shown in (B), the top plate 10 moves in the direction of the other end 2B by the chain conveyor 9, and the confectionery bread 11 on the top plate 10 is scooped from the top plate side edge 2A by the flat conveyor 2 and flattened. Although the flat conveyor 2 is placed on the conveyor 2 and inclined upward from the top plate side edge 2A toward the other end 2B, the confectionery bread 1
In some cases, the behavior of 1 becomes unstable, that is, the confectionery bread 11 moves back and forth between the top plate 10 and the flat conveyor 2, and the change on the flat conveyor 2 may not be smooth.

The timer 6 receives the signal from the photoelectric sensor 5, after the time required for the top 10 to move by the predetermined distance, further sets the distance corresponding to the entire length of the top 10 in the moving direction of the top 10 to the top 10. At a point in time after the time required for the movement, the motor 7 for rotating the product drop prevention member and the motor 8 for swinging the flat conveyor are energized. This time point is the rising piece 1 on the rear side in the moving direction of the tabletop 10 whose presence is detected by the photoelectric sensor 5.
0B is a point in time approaching the top edge 2A. Therefore, as shown in FIG. 2C, the controller 4
By energizing the product fall prevention body rotating motor 7 and the flat conveyor swinging motor 8 at the time point from the timer 6, the rising piece 10B on the rear side in the moving direction of the top plate 10 is moved to the top plate side edge 2A. When approaching, the flat conveyor 2 is swung from the scooping position to the avoidance position, and the product drop prevention body 3 is rotated from the passing position to the drop prevention position. At this time, the product fall prevention body 3 rotates in a direction to push the confectionery bread 11 on the flat conveyor 2 to the other end 2B.
Therefore, the product fall prevention body 3 not only prevents the confectionery bread 11 from falling, but also a push plate having an effect of pushing the confectionery bread 11 whose behavior is unstable between the top plate 10 and the flat conveyor 2 onto the flat conveyor 2. is there. And the product fall prevention body 3 which is a rectangular plate is in the fall prevention position.
The long side of the flat conveyor 2 is parallel to the width of the flat conveyor 2 and both short sides thereof are at both ends of the top side edge 2A.
Exists at a position almost perpendicular to the flat conveyor 2,
The long side of the product fall prevention body 3 is substantially the same as the width of the flat conveyor 2 and its short side is longer than the height of the confectionery bread 11 to be conveyed. The edge 2A is present over the entire width of the flat conveyor 2 and the height from the flat conveyor 2 is higher than the height of the confectionery bread 11.

The rotation of the product drop prevention member 3 causes the top plate 10 to rotate.
The upper confectionery breads 11 are all placed on the flat conveyor 2,
At the same time, the flat conveyor 2 swings from the scooping position to the avoidance position, and the empty top plate 10 passes below the flat conveyor 2. Next, the sweet bun 11 placed on the flat conveyor 2
Is transported to the other end 2B by the movement of the belt of the flat conveyor 2 and moves onto a product feed belt conveyor 17 provided continuously with the flat conveyor 2. At the time of swinging the flat conveyor 2 to the avoidance position and after the swing, the confectionery bread 11 is placed on the flat conveyor 2 that is installed to be inclined upward from the top edge 2A toward the other end 2B.
Is slipped in the direction of the top edge 2A, the top edge 2
Since the product fall prevention body 3 is located at the fall prevention position at A, the confectionery bread 11 that has slipped down to the top plate side edge 2A is stopped and supported by the product fall prevention body 3. The product fall prevention body 3 is provided over the entire width of the flat conveyor 2, and the height from the flat conveyor 2 is the confectionery bread 1.
1 is higher than the height of the confectionery bread 11 so that the top plate side edge 2A
Is more reliably prevented.

Next, the top plate 10 after being conveyed following the front top plate 10 by the chain conveyor 9 is placed on the flat conveyor 2.
When the photoelectric sensor 5 moves to the photoelectric sensor 5 installed a predetermined distance before the photoelectric sensor 5, the photoelectric sensor 5 inputs a presence signal of the top 10 to the timer 6. After the signal is input, the timer 6 sets the constant distance to the top 10. After the time required for the product to move, the product fall prevention body rotating motor 7 and the flat conveyor swinging motor 8 are energized, and as shown in FIG. 2A, the flat conveyor 2 and the product fall prevention body 3 are again turned on. The buns 1 are moved to the scooping position and the passing position, respectively, and
1 is skimmed by the flat conveyor 2. Before swinging the flat conveyor 2 to the scooping position, the confectionery pans 11 on the front top plate 10 are all moved on the product feed belt conveyor 17 and the distance between the front and rear top plates 10, 10 and the chain. The moving speed of the conveyor 9 is adjusted. Thereafter, as described above, when the rising piece 10B on the rear side in the moving direction of the later top plate 10 approaches the top edge 2A, as shown in FIG. The conveyor 2 and the product fall prevention body 3 are moved to the avoidance position and the fall prevention position, respectively, and when the flat conveyor 2 swings to the avoidance position and after the swing, the sweet bun 11 falls from the flat conveyor 2 when the product falls. This is prevented by the prevention body 3 being located at the fall prevention position. As described above, the confectionery bread 11 on the top plate 10 which is continuously conveyed by the chain conveyor 9 to the depanner 1 with the product drop prevention mechanism of the present example is formed by the presence of the product drop prevention body 3 interlocked with the swing of the flat conveyor 2 When the flat conveyor 2 swings to the avoidance position and after swinging, the flat conveyor 2 is prevented from dropping on the flat conveyor 2, and is sequentially taken off from the top 10 by the flat conveyor 2 and separated.

Note that the rotation of the product drop prevention body 3 does not have to be simultaneous with the swinging of the flat conveyor 2, and even before the flat conveyor 2 swings from the avoidance position to the scooping position.
After all the confectionery breads 11 on the flat conveyor 2 have moved onto the product feed belt conveyor 17, the product drop prevention body 3 may rotate from the drop prevention position to the passing position, while the flat conveyor 2 is in the scooping position. Even before swinging to the avoidance position, after all the confectionery bread 11 on the top plate 10 has moved onto the flat conveyor 2, the product fall prevention body 3 rotates from the passing position to the fall prevention position. Is also good.
Further, the product fall prevention body 3 only needs to be able to move to both the passing position and the fall prevention position, and the mode of the movement is not limited to the case of this example. Is moved in a direction in which the product fall prevention body 3 pushes the confectionery bread 11 onto the flat conveyor 2, so that the confectionery bread 11 whose behavior is unstable moves to the fall prevention position of the product fall prevention body 3. This also has the effect of being pushed onto the flat conveyor 2, which is more preferable.

[0015]

According to the depanner with the product drop prevention mechanism of the present invention, when the flat conveyor swings to the avoidance position for avoiding the rising piece formed on the peripheral edge of the top plate, the product drop prevention body is moved upward. The product on the flat conveyor is prevented from dropping from the top plate side edge by being located at the drop prevention position that substantially closes the gap allowing the product to pass between the plate side edge and the plate side edge. Therefore, occurrence of defective products can be prevented very effectively.
