Description

The present invention relates to a food conveyance device for a batch-type food cleaning device that cleans foods such as vegetables, seaweed, and seafood at a fixed rate.

The present applicant has already proposed a food washing apparatus (see Patent Documents 1 and 2).
This food cleaning device conveys food (vegetables, etc.) supplied to the food input part to the food take-out part side while washing it in the conveyance washing path, and takes out the food to be washed conveyed to the food take-out part It was a continuous cleaning device that was taken out of the cleaning tank.
In such a continuous cleaning apparatus, food can be continuously supplied by a conveyor.

However, in a batch-type food cleaning apparatus that repeatedly performs the process of cleaning and discharging food that has been put in a certain amount into the cleaning tank as one cycle, it is not possible to continuously supply food by a conveyor.

Conventionally, when food is supplied to a batch-type food cleaning apparatus, a predetermined sliced food is stored in a container or a dehydrated basket and is manually carried and put into a cleaning tank.
In such a manual operation, foreign substances such as hair may be mixed, and it is required to reduce the manual operation as much as possible.

In addition, in a batch type food cleaning apparatus, when a larger amount of food than an appropriate amount is supplied to the cleaning tank, the cleaning action, the foreign matter removing action, and the sterilizing action are reduced, and a sufficient cleaning effect cannot be obtained.

Moreover, in the batch type food washing apparatus, since the volume of the washing tank is determined, the supply amount is measured not by the weight of the food but by the volume.
In this case, since the specific gravity of the food to be cleaned differs depending on the type, it is necessary to be able to set the input weight in order to convert it into a volume.

Therefore, in the present invention, labor can be saved by reducing manual work, and an appropriate amount of food can be stably supplied by setting the input weight, thereby reducing contamination of foreign matters. In addition, it is possible to maximize the cleaning action, foreign substance removal action, and sterilization action in the batch type food washing device , and the contained food does not form a bridge in the weighing hopper and stays in place. It is an object of the present invention to provide a food conveyance device that can be discharged into a batch type food cleaning device .

In order to solve the above problems, the food conveying device of the present invention (Claim 1)
A food transport device to a batch type food cleaning device that repeats the process from washing and discharging a fixed amount of food into a washing tank as one cycle,

FIG. 3 shows a state where the discharge chute and the side opening / closing lid are opened.
In this embodiment, the case where the food to be cleaned is vegetable is taken as an example.
In addition, not only vegetables but seafood, seafood, and other foods that require cleaning treatment can be targeted.

In the figure, reference numeral 1 denotes a conveyer (belt conveyer), which includes an electric motor 10 with an inverter, is supported by a frame 11 so as to incline upward from the start end toward the end, and a vegetable slicer 2 to be conveyed above the start end. Is provided, and a weighing hopper is provided below the terminal end, and a batch type vegetable washing device 4 is disposed below the weighing hopper 3.

The batch-type vegetable cleaning device 4 is formed so as to repeatedly perform the process from cleaning and discharging the food charged in a certain amount to the cleaning tank 40 as one cycle, and is limited to its specific configuration. In short, the conveying device of the present invention can be applied as long as the food is washed by a certain amount.

The weighing hopper 3 is attached to a bracket 12 provided on the frame 11 of the conveyor 1 via a load cell 7.

The weighing hopper 3 includes a rectangular tube-shaped hopper main body 30, and a bottom opening 31 that faces the washing tank 40 of the batch type vegetable washing apparatus 4 is formed on the bottom thereof, and a discharge chute 32 is opened and closed at the bottom opening 31. It is provided as possible.
Further, a side discharge port 34 communicating with the bottom opening 31 is formed in the side wall 33 of the hopper body 30 on the front end side of the discharge chute 32 by notching from the middle to the lower end, and this side discharge port 34 is formed. In addition, a side opening / closing lid 35 that opens and closes simultaneously with the opening / closing operation of the discharge chute 32 is provided.

The opening / closing structure of the discharge chute 32 and the side opening / closing lid 35 will be described.
A base end portion of the discharge chute 32 is attached to a support shaft 50 that is pivotally supported at the lower end of the hopper body 30 so that the bottom opening 31 can be opened and closed, and a tip end of a cylinder 51 connected to the hopper body 30 is the support shaft. It is connected to an arm 52 attached to 50.
A support shaft 53 is pivotally supported on the side wall 33 of the hopper body 30 at the upper end of the side discharge port 34 so that the base end portion of the side opening / closing lid 35 can open and close the side discharge port 34. The arm 56 attached to the support shaft 50 and the arm 54 attached to the support shaft 53 are connected by a rod 55.

Therefore, in the state where the cylinder 51 is extended, the bottom opening 31 is closed by the discharge chute 32 and the side discharge port 34 is closed by the side opening / closing lid 35 as shown in FIG.
When the cylinder 51 is shortened, as shown in FIG. 3, the discharge chute 32 is rotated downward to open the bottom opening 31, and at the same time, the side opening / closing lid 35 is rotated outward via the rod 55. Then, the side discharge port 34 is opened.

The discharge chute 32 is formed in a bowl shape in which a triangular side plate 32 a is formed on both sides of the discharge chute 32. When the discharge chute 32 is opened, the side plate 32 a is formed on both sides of the bottom opening 31. The vegetable which is the food to be cleaned is prevented from spilling sideways from both sides of the bottom opening 31 and the vegetables sliding down on the discharge chute 32 are prevented from spilling sideways.
The opening / closing structure of the discharge chute and the side opening / closing lid is not limited to the embodiment, and the actuator is not limited to the cylinder.

The load cell 7 is a sensor that measures weight as a load transducer, and is composed of three members: a strain generating body, a strain gauge, and a bridge circuit.
When a load is input to the strain generating body, it is deformed and distorted. This strain is replaced with a change in electrical resistance by a strain gauge, the change in electrical resistance is replaced with a voltage change by a bridge circuit, and finally the weight is output as a change in voltage.

In the embodiment, an output signal obtained by replacing the weight of the vegetable housed in the hopper body 30 with a voltage is input from the load cell 7 to the control device 70, and the control device 70 causes the electric motor 10 and the weighing of the transport conveyor 1 to be output. The operation of the cylinder 51 of the hopper 3 is controlled.

Therefore, the vegetables shredded by the slicer 2 are transported by the transport conveyor 1, fall from the terminal end, and are accommodated in the hopper body 30 of the weighing hopper 3. At this time, the discharge chute 32 and the side opening / closing lid 35 of the weighing hopper 3 are closed as shown in FIG.

And if the weight of the vegetable accommodated in the hopper main body 30 reaches the preset weight input into the control apparatus 70 previously, the conveyance conveyor 1 will stop and supply of the vegetable to the hopper main body 30 will stop.

In this case, in this embodiment, when a set weight (for example, 10 kg) is input in advance to the control device 70 and an amount of vegetables slightly smaller than the set weight is stored in the hopper body 30 (for example, 9.5 kg) ) Decrease the rotation speed of the electric motor 10 to lower the transfer speed of the conveyor 1, and if further vegetables are accommodated (for example, 9.8 kg), the transfer speed of the conveyor 1 is further reduced and the set weight of vegetables Is stored (10 kg), the rotation of the electric motor 10 is stopped to stop the conveyor 1 and the supply of vegetables to the hopper body 30 is stopped.

In the control of the transport conveyor 1, in the embodiment, the transition speed is stopped after being lowered in two stages, but may be stopped after being reduced in one stage or multiple stages of three stages or more, You may make it stop immediately with a set weight, without reducing.

When the conveyor 1 is thus stopped, the cylinder 51 is shortened at the same time, the discharge chute 32 and the side opening / closing lid 35 are opened as shown in FIG. 3, and the vegetables stored in the hopper body 30 are the batch type. It is put into the washing tank 40 of the vegetable washing apparatus 4.

Then, after the vegetables stored in the hopper body 30 are discharged, the discharge chute 32 and the side opening / closing lid 35 are returned to the position of FIG. 2 and the bottom opening 31 and the side discharge port 34 are closed, Thereafter, the vegetables are again stored in the hopper body 30 by the same operation as described above.

When the discharge chute 32 and the side opening / closing lid 35 are opened and the vegetables are put into the washing tank 40 of the batch type vegetable washing apparatus 4, the washed vegetables are discharged from the washing tank 40 in the batch type vegetable washing apparatus 4. It is necessary to carry out in a state where
Further, when the conveyor 1 is stopped, the slicer 2 also needs to be stopped. For example, it is possible to simultaneously stop the conveyor 1 and the slicer 2 by interlocking electricity.
Based on such a thing, the operation timing of the food conveyance apparatus of this invention, the operation timing of a slicer, and the operation timing of a batch type food washing apparatus are each controlled.
