Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a jelly feeding device.

[Prior Art] When filling a cup containing pulp with a jelly, a conventional jelly feeder generally supplies a certain amount of jelly to the cup containing pulp each time.

However, since the type and size of pulp contained in the cup are not constant, the amount of jelly to be filled in the cup is conventionally determined according to the inner volume of the cup when the pulp of small size is contained. Therefore, when a large-sized pulp is contained, the remaining volume in the cup becomes small, but even in that case, the above-mentioned fixed amount of jelly is filled as it is.

[Problems to be solved by the invention] However, even when the flesh is large as described above, when a certain amount of jelly is supplied as in the case where the flesh is small, a large amount of jelly is supplied to the cup, and excess jelly is removed from the cup. The jelly is wasted because it needs to be eliminated.
In addition, the sealing surface of the cup edge, when removing the jelly,
Since it becomes dirty with jelly, poor sealing occurs. Further, contrary to the above, when the amount of pulp is small, a certain amount of jelly is supplied, so that the jelly does not reach the specified amount, which is rather unfavorable for the quality of the cup jelly.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a jelly supply device capable of always supplying a prescribed amount of jelly into the cup even if the size of the pulp contained in the cup changes. is there.

[Means for Solving the Problems] The present invention includes a positive displacement piston type filling pump that includes a pump piston that can be moved up and down by an actuator, and that sucks the jelly when the pump piston moves up and discharges the jelly when the pump piston moves down. A weight detector for measuring at least the weight of the cup containing the pulp so that the weight is less than the specified weight to be filled, the weight of the cup containing at least the pulp measured by the weight detector, and the pulp to be filled in the cup, and A calculator that determines the weight of the jelly to be added / injected by the filling pump from the specified weight of the jelly, and the pump piston of the filling pump is lowered by an amount corresponding to the weight of the jelly to be added / injected calculated by the calculator. A control device for giving a command to the actuator is provided.

[Operation] When a jelly is filled in a pulp-containing cup, at least the weight of the cup containing the pulp is measured with a weight detector so that the weight is less than the specified weight, and the calculated weight and the specified weight to be filled into the calculator The weight of jelly to be added / filled by the filling pump is calculated by the above, the actuator is driven by the command from the control device, and the pump piston of the filling pump is lowered by the actuator by the amount corresponding to the weight calculated by the arithmetic unit. Let As a result, it becomes possible to fill the cup with the jelly without excess or deficiency.

To provide.

A lifting cylinder 9 on a pedestal 8 is attached to the weight measuring stage 7.
A weight detector 11 such as a load cell that can be moved up and down through a cup is supported on the upper surface of the weight detector 11 and the weight of the cup 4 can be transmitted to the weight detector 11. Install 13.

A shortage jelly supply stage 16 provided with an actuator 14 and a filling pump 15 is provided in front of the weight measuring stage 7 in the traveling direction so that the jelly to be additionally added and filled in the cup 4 can be metered and supplied.

When the capacity of the filling pump 15 is larger than the specified amount after filling, the primary injection stage 6 is unnecessary, and the weight measuring stage 7 measures the weight of the cup 4 containing only the pulp.

As shown in FIG. 2, the filling pump 15 includes a pump piston 18 which is slidable up and down in a pump cylinder 17, and a pump piston which is attached to a lower portion of the pump cylinder 17 and
The inlet pipe 21 that can suck the jelly 20 into the lower part of the pump piston 18 in the pump cylinder 17 through the check valve 19 by the ascent of 18 and the check valve 22 that is attached to the lower end of the pump cylinder 17 and descends by the pump piston 18. An outlet pipe 23 capable of discharging the jelly 20 to the outside of the pump cylinder 17 is provided, and a nozzle 24 for discharging the jelly 20 toward the cup 4 is attached to the lower end of the outlet pipe 23.

The actuator 14 includes a rod 25 extending downward from the upper surface of the pump piston 18, an air piston 27 connected to an upper end of the rod 25 and slidable up and down in an air cylinder 26, and above the air cylinder 26. A solenoid valve 31 is provided which is connected to each of the upper port 28 and the lower port 29 below and switches the inflow direction of the pressurized air 30 into the air cylinder 26.

Further, a bar member 32 is projected from the upper surface of the air piston 27 to the outside of the air cylinder 26 so that the amount of elevation of the bar member 32 can be detected by a potentiometer 33 provided outside the actuator 14.

The weight detector 11 of the weight measuring stage 7 can compare and calculate the weight of the cup 4 containing the flesh and jelly measured by the weight detector 11 and the preset prescribed weight of the flesh and jelly to be filled. Connect the arithmetic unit 34,

Weigh the pulp and jelly injected into the.

As shown in FIG. 2, the weight measurement value B is input to the input device 35 in advance.
When the set value A, which is the specified weight, is input to the calculator 34, the difference A− between the set value A and the measured value B is calculated by the calculator 34.
B is calculated, and a correction coefficient C for correcting the difference in specific gravity between pulp and jelly is input to this value from the input device 36, and the weight of the jelly to be filled is calculated by (A−B) × C = D. Then, the calculated value D is given to the control device 37, and the control device 37 obtains the descending amount of the pump piston 18 of the filling pump 15 from the calculated value D.

During this time, the cup 4 is in the shortage jelly supply stage.
Moving to 16, the control device 37 gives a command signal D'corresponding to the calculated lowering amount of the pump piston 18 to the solenoid valve 31 to switch the solenoid valve 31, and the pressurized air 30 is supplied to the air cylinder 26. Of the filling pump 15 to lower the pump piston 18 of the filling pump 15.
The jelly 20 is extruded from the filling pump 15 by the 18 and the shortage jelly is filled in the cup 4. At this time, the descending amount of the bar member 32, that is, the descending amount of the pump piston 18 is detected by the potentiometer 33, and the descending amount signal E is sent to the controller 37, and the command signal D'and the descending amount signal from the potentiometer 33 are detected. When E matches, the command signal D'from the control device 37 is not given to the solenoid valve 31 and the solenoid valve 31
31 is switched. Therefore, the pressurized air 30 is supplied below the air piston 27 of the air cylinder 26, and the air piston 27
As a result, the pump piston 18 also rises, and the jelly 20 is sucked into the lower portion of the pump piston 18 of the pump cylinder 17, and at the same time, the filling and discharging of the jelly 20 is stopped.

As described above, the weight of the jelly cup 4 containing the flesh is measured in advance to calculate the shortage, and the filling pump 15 supplies only the shortage. It becomes possible to fill.

Also, the volume of the inside of the cup 4 corresponding to the weight of jelly to be added or filled differs depending on the specific gravity of the pulp, but since the specific gravity of the pulp is taken into consideration when calculating the weight of the shortage jelly, the cup 4 The accuracy of the weight of the pulp and the jelly filled in is good.

In the above embodiment, the air cylinder is used as the actuator 14, but the pump piston 18 may be moved up and down by the movement of the screw, and other various changes may be made without departing from the scope of the present invention. Of course, it can be added.

[Effects of the Invention] As described above, according to the present invention, the specified amount of jelly can be filled in the cup without excess or deficiency, so that the jelly can be saved and the edge of the cup can be soiled with the jelly. Without this, it is possible to prevent the sealing failure and further improve the product quality.
