Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a filling amount adjusting device in a machine for filling canned foods such as flaky fish meat.

BACKGROUND ART Conventionally, as a machine for filling empty cans with flaky fish meat such as tuna and bonito, a measuring basin having a constant volume is provided at the bottom of an opening drilled in the turntable surface, and the measuring basin is used to fill empty cans with flaky fish meat such as tuna and bonito. A certain volume of fish meat is obtained by scraping the flaky fish meat with a scraper, and a shutter plate provided at the bottom of the tank is opened to fill an empty can located below the tank with the fish meat in the tank. It has been known.

However, in the case of flaky fish meat, even if it is measured to a constant volume in a basin, the amount is not always constant, and changes with changes in the meat quality, such as the water content of the fish meat and the size of the flakes. For example, tuna tuna 3
In the case of No. 1 cans, the actual filling amount varies by about 4 to 6 g. To prevent such fluctuations in filling amount,
In conventional devices, the amount of stuffed meat is adjusted in response to changes in meat quality by changing the volume of the box each time, or by manually performing correction filling after filling. Therefore, the conventional can manufacturing line not only requires a lot of manpower and has poor working efficiency, but also still cannot eliminate the variation in filling amount.

Problems to be Solved by the Invention The present invention has been devised in view of the above-mentioned circumstances, and is a filling machine for filling empty cans with flaky or granular meat such as fish or beef, as well as granular materials. An object of the present invention is to provide a filling amount adjusting device that can automatically adjust the filling amount during filling operation in response to changes in the meat quality of the contents, etc., and can increase the correct weight ratio of the filling amount. It is something.

Means for Solving the Problems The present invention makes it possible to finely adjust the amount of filling without changing the volume of the weighing well by making it possible to adjust the amount of filling that rises to the top of the weighing well. It was completed by discovering.

That is, the filling amount adjusting device in the can filling machine of the present invention supplies the filling to the upper surface of the turntable which has a filling amount measuring basin on the lower surface, and causes the filling to fall into the measuring basin by rotation of the turntable. In a can filling machine that weighs and drops the filling into empty cans, the turntable is composed of an upper table and a lower table that are installed so that the interval can be adjusted, and the filling amount measuring box is An upper cylinder fixed to an upper table and a lower cylinder fixed to a lower table are slidably fitted to each other, and the turntable is in a position immediately before dropping the filling in the measuring well into an empty can. The above problem was solved by adopting a configuration characterized in that a rotating brush is provided above the weighing pan so that its spacing from the turntable surface can be adjusted.

Function: As the turntable rotates, the filling material falls into the weighing well, and eventually the weighing well becomes full and piles up. Furthermore, when the turntable rotates and is positioned below the rotating brush, the filling that has risen at the top of the weighing pan due to the rotation of the rotating brush is evened out to the distance between the tooth tip of the rotating brush and the table surface. The height of the bulge is adjusted to be constant, and a predetermined filling amount is obtained. Therefore, if it is necessary to fine-tune the filling amount depending on the quality of fish meat, etc., even during production, by adjusting the distance between the rotating brush and the table surface,
The filling amount can be finely adjusted without changing the volume of the measuring well. Thereby, it is possible to always obtain an appropriate filling amount in response to changes in meat quality, etc. Furthermore, by changing the distance between the upper table and the lower table, the upper cylinder and the lower cylinder can slide relative to each other, and the volume of the weighing basin can be changed. Thereby, it is possible to easily respond to changes in the filling amount due to changes in the type of can.

Embodiments Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

1 to 4 show an embodiment of the filling amount adjusting device according to the present invention. In the figure, 1 is a rotary table having an upper table 2 and a lower table 3, and the interval between the upper table 2 and the lower table 3 is adjustable. Upper table 2
The lower table 3 is provided with holes 5 at predetermined pitches for installing a weighing box. The weighing box 6 is
The upper cylinder 7 fixed to the upper table 2 and the lower cylinder 8 fixed to the lower table 3 are slidably fitted, and the volume can be changed by changing the interval between the upper and lower tables. I can do things.
A shutter plate 9 is provided at the bottom of the lower cylinder 8, and the contents can be dropped from the measuring well into the empty can. An empty can holding table 4 is provided below the shutter plate 9 and rotates in synchronization with the turntable, holding empty cans at a position below the weighing box and rotating together with the turntable.

On the upper surface of the upper table, there are scrapers 10 and 1 provided on the machine base along the outer periphery of the table.
1 and 12 are arranged so that as the rotary table rotates, flaky fish meat supplied on the table is gradually scraped up to the upper part of the opening and falls into the weighing chamber 6.

Reference numeral 15 denotes a stainless steel rotary brush for adjusting the final filling amount, and is installed after the process in which the scraper finishes filling the measuring box. The rotating brush 15 is held on the machine base via a spacing adjustment mechanism 16 so that the spacing from the turntable surface can be adjusted depending on the amount of stuffing. The interval adjustment mechanism 16 is connected to the rotating shaft 1 of the rotating brush 15.
A driving device 18 such as a motor for rotationally driving the vertical movement lever 7 is supported at the top of a vertically moving rod 20, and the vertically moving rod 20 is configured to be adjusted up and down by a suitable vertical movement mechanism. The vertical movement mechanism includes, for example, a rack 21 formed on the vertical movement rod 20, and a pinion 22 that engages with the rack 21 to move the rack up and down.
, and furthermore, the vertical position of the vertical moving rod is set to 1, for example.
An appropriate mechanism can be adopted, such as providing a sensor 23 that can detect the distance at mm intervals, detecting the height position with the sensor, and controlling the motor that rotates the pinion to adjust the interval.

In the figure, 25 is a plunger for dropping the contents of the measuring well into the empty can c, 27 is a supply turret, and 28 is a discharge turret.

Next, a case will be described in which flaky fish meat is filled using the filling amount adjusting device of this embodiment configured as described above. In advance, adjust the distance between the upper table 2 and the lower table according to the filling amount,
The volume of the measuring well is set to a predetermined volume. Empty cans c transported by the transport conveyor are adjusted in pitch to the pitch of the weighing box of the turntable by the supply turret 27, and transferred to the can holding turntable 4 which rotates in synchronization with the turntable 1.
and rotates while being positioned below the weighing box 6. At that stage, the lower surface of the weighing pan is closed with the shutter plate 9. On the other hand, flaky fish meat is supplied to the upper table 2 surface of the turntable 1 by a flaky fish feeding device (not shown). As the turntable rotates, the fish meat is gradually scraped up to the opening by the scrapers 10, 11, and 12 and falls into the weighing chamber. In this way, in the illustrated embodiment, the weighing pan 6 becomes full and becomes heaped up while the turntable rotates about half a turn. Furthermore, when the turntable rotates and is positioned below the rotating brush 15, the flaky fish meat that has risen at the top of the weighing box due to the rotation of the rotating brush 15 is spread between the tooth tips of the rotating brush and the table surface. It is leveled and adjusted so that the raised height is constant. Therefore, if it is necessary to fine-tune the filling amount depending on meat quality, etc., even during manufacturing, the pinion drive motor of the interval adjustment mechanism can be driven to move the vertically moving rod up and down to a predetermined position. By adjusting the distance between the brush and the table surface, the filling amount can be finely adjusted without changing the volume of the measuring well. Thereby, an appropriate filling amount can always be obtained. In the case of this embodiment, since the interval adjustment mechanism can be adjusted at intervals of 1 mm, the filling amount can be adjusted extremely finely.

In this way, when the appropriate filling amount of the tub reaches the lower position of the plunger 25, the shutter plate 9 opens and the plunger 25 descends, dropping the fish meat in the tub into the empty can and filling it. finish. The cans that have been filled are returned to the can transport conveyor 26 by the discharge turret 23, and are transported by the can transport conveyor 26 to the next process, the lid seaming process.

The filling amount adjusting device of the canned filling machine of the present invention is not limited to the above-mentioned embodiment, and various design changes are possible.Furthermore, the filling material is not limited to flaky fish meat, but can also be filled with flakes, granules, etc. Any equivalent filling can be applied.

Effects As described above, according to the filling amount adjustment device for a can filling machine of the present invention, the filling amount can be finely adjusted in response to changes in the meat quality of the filling, etc., without changing the volume of the measuring well, even during work. Since it can be easily and automatically adjusted, there is no need for correction filling work to correct variations in filling amount due to changes in meat quality, etc., which was previously done manually, making it efficient and efficient. The filling rate can be dramatically increased compared to the conventional method.

Furthermore, since the volume of the measuring well can be easily changed, it is possible to easily respond to changes in the filling amount due to changes in the type of can, etc.
