Guide sprocket 43 ...
And the guide sprockets 43 ...
The two chains 44, 44 are laid in a symmetrical arrangement on the left and right sides, and the slats 45 with a U-shaped cross section are placed between these chains 44, 44.
... (see FIG. 2) are attached in a crossover manner and continuously along the chain 44 to form a chain conveyor 46, and the chain conveyor 46 is formed by a motor 47 arranged below the horizontal frame 42. The defective product detection means 48, 49 for detecting defective products in the middle of the conveying path of the chain conveyor 46, and the defective products detected by the defective product detection means 48, 49 are excluded. In order to do so, defective product removing means 50 is provided.

Two types of defective product detection means 48, 49 in this example are provided, one of which is a locking transfer chain 51 for making the polyshoe containing colored juice, which is the load A, in an oblique posture, a chain conveyor 46. Is arranged along one side and the locking and conveying chain 51 is moved in synchronization with the chain conveyor 46, and as shown in FIG. A pair of optical sensors 52, 52 for seeing through the upper part of the shoe A are provided.
Now, when the juice liquid level 53 does not emit a detection signal when it is like the two-dot chain line in FIG. 4, but when it is like the solid line, the optical sensors 52, 52 emit a detection signal based on the increase in the amount of transmitted light. The other one is shown in Fig. 5 (a).
As shown in (b), a pressing arm 55, which is always pressed downward by a spring 54 and the like, and a sensor 56 for detecting the displacement of the pressing arm 55 are provided, and are close to the bottom surface of the slat 45 of the chain conveyor 46. As described above, if the notch 45a is provided in the slat 45 so that the pressing arm 55 can be oscillated and displaced, and if the colored shoe containing colored juice A is torn and the juice leaks out, the pressing arm 55 is Polyshoe A with colored juice in slats 45
The sensor 56 is configured to emit a detection signal based on this displacement because it is flattened by the pressing force and is largely displaced by swinging. In FIG. 4, reference numeral 57 is a locking plate for holding the polyshoe shoe A with the obliquely colored colored juice so as not to fall off the slats 45. Also,
In any defective product detection means 48, 49, if they are always in the defective product detectable state, the slats 45
..Because no colored shoes A with colored juice are present between each other, an incorrect detection signal is emitted. Therefore, colored shoes A with colored juice A of each slat 4 are used.
Is provided with a control mechanism (not shown) so that the defective product detecting means 48, 49 can be in the defective product detectable state only when the defective product detecting means 48, 49 have reached the detection locations.

Further, the defective product removing means 50 in this example is the defective product detecting means 49.
Is located on the front side, that is, the conveying direction side, on one side of the chain conveyor 46, an injection nozzle 58 for injecting a compressed fluid such as air is provided, and in the middle of the pipe communicating with the injection nozzle 58. A solenoid valve 59 is interposed, and based on the detection signal of the defective product detection means 48 or 49, the electromagnetic valve 59 is opened when the defective product has just reached the position facing the injection nozzle 58. The compressed fluid is ejected to operate to blow away the colored juice-containing poly shoes A in the slats 45.

In addition, 60 is a control device, 61 is a caster, and 62 is polyshoe A with colored juice on the chute 7 ...
It is a sensor that detects that the number has exceeded a certain amount.

The operation of the above structure will be described. Now, the container B in which the colored shoe A with colored juice is inserted in a fixed posture is conveyed from the rear, and the container feeding conveyor 3
When it reaches the upper position, the motors 3 are appropriately operated to cause the container feeding conveyors 1 and 2 to insert the container B into the container receiving structure 15 through the insertion port 30 and set the container B in place. In this connection, the container receiving structure 15 is started to invert by the drive means 16. When the container receiving structure 15 approaches the inverted position, the tip of the abutting member 36 provided on the slide plate 21 abuts on the upper edge of the receiving plate 40 ,. As the tip of the abutting member 36 is moved upward while being slidably contacted with the upper edge of the receiving plate 40 ... As the number of slides increases, the slide plate 21 is gradually displaced upward to receive the container. When the structure 15 is completely in the inverted position, the amount of upward displacement thereof is appropriate, that is, the diameter of the colored juice-containing polyshoe shoe A is several times as large. As shown in FIG. 2B, the container receiving structure 15 and the upper open type container B in the inverted position are in an open state as shown in FIG. -Is gradually rolled into the hopper 6 while maintaining a constant posture by its own weight in order from the lower part through the appropriately opened part. The colored juice-containing polyshoes A ... Rolled in this way are preferably lowered toward the tip while maintaining a substantially fixed posture on the vibrating bottom plate 6b, and finally the slats 45 of the chain conveyor 46 ... It reaches the position where it touches the slat 45, and is corrected to the position along the slat 45 accurately by the collision with the slat 45. Be done. And poly shoes A with colored juice that rolls in one after another ...
When a certain amount of slat 45 stays in contact with slat 45, the load supply system from container B to slat 45 reaches an equilibrium state. .. are sequentially carried out from the front side, and on the other hand, the carried out amount is supplied from the container B side into the hopper 6.
Thus, after a certain period of time, all of the colored juice-containing polyshoes A in the container B in the inverted posture are supplied into the hopper 6 and are carried out toward the chute 7. This state is detected by, for example, an optical sensor (not shown) attached to the container receiving structure 15 and the container receiving structure is detected.
15 can be returned to its original position. Following this, the cylinder devices 27, 27 are driven to open the discharge door 29. As a result, the container B is dropped by its own weight onto the container delivery conveyor 10 below. After this, the discharge door
29 is closed, the container receiving structure 15 is inserted with the next container B, and the same operation as described above is repeated. On the other hand, the container B on the container delivery conveyor 10 is a container delivery conveyor.
10 will be sent to the appropriate place.

Further, the colored juice-containing poly shoes A ... which are conveyed toward the chute 7 by the slats 45 ... Detected and were rejected by the defective product detecting means 48, 49 and the defective product removing means 50. After that, it is sent to the shoot 7. If the number of colored juice-containing polyshoes A sent to the chute 7 increases and it stays on the chute 7, the sensor 62 detects it and stops the device of the present invention. Thus, the colored juice-containing polyshoes A are automatically delivered to the chute 7 in appropriate amounts.

(Effects of the Invention) As described above, according to the present invention, the hopper (the colored shoe containing colored juice) A ... 16 can be supplied into the hopper 6, and a great labor saving can be achieved in the work of supplying the load A ... into the hopper 6 and sequentially sending the load A. is there.

Further, according to the embodiment, since the defective product detecting means 48, 49 and the defective product removing means 50 are provided in the middle of the conveying path of the conveying device 8, there is a defective product in the package A in the container B. Even if they are mixed, it is possible to prevent defective products from being sent to the outside. Further, since the bottom sol 6b is vibrated by the cam body 39, there is no inconvenience such as the load A being caught in the hopper 6. There are advantages.
