Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a constant quantity filling machine suitable for filling viscous raw materials, particularly salad, mayonnaise and the like with mixed vegetables and other solid substances inside.

[0002]

2. Description of the Related Art As a filling machine for viscous raw materials such as mayonnaise and salad, the filling cylinder supplies a rotor having a filling cylinder in the main body with a feed hole of a raw material supply hopper obliquely above and a discharge hole obliquely below. A reciprocating rotary hole is provided between the hole and the discharge hole, and a working cylinder for reciprocating a piston fitted in a filling cylinder is projectingly fixed to the rotor, and the working cylinder is rotated by a driving cylinder. Japanese Utility Model Publication No. 49-11239 discloses a method in which the raw material in the raw material supply hopper is sucked into a filling cylinder and is quantitatively filled from a discharge hole.

[0003]

However, in the conventional method, the raw material in the raw material supply hopper is formed so as to enter the filling cylinder in the rotor from diagonally above and to be discharged to the discharge hole diagonally below. In order to fill the material, a pressure lid is required on the upper part of the raw material supply hopper, a nozzle-shaped cover is required for the discharge hole, and the viscous material remains attached to the discharge hole, which reduces the filling accuracy and becomes unsanitary. There is a problem. An object of the present invention is to provide a filling machine capable of improving these defects and efficiently and surely quantitatively filling a viscous raw material.

[0004]

In order to achieve the above-mentioned object, the present invention reciprocates in an outer shell which vertically has an upper suction hole and a lower filling hole which communicate with a raw material supply hopper. A cylindrical rotor that makes a half rotation about the horizontal axis by a moving means is fitted in a state in which the peripheral surface of the rotor is in close contact with the outer frame, and the open end of the rotor is in close communication with the suction hole or the filling hole. It is characterized in that a metering cylinder capable of being fitted and having a piston inserted therein is provided, and that the piston is provided with a piston suction / discharge device that operates in conjunction with the reciprocating rotation means and a piston stroke adjusting mechanism.

The outer body frame is made of stainless steel, and especially, the surface of the rotor which is in sliding contact with the outer body frame has a molecular weight of 55.
When it is made of high molecular weight polyethylene resin of more than 0,000,
The rotor can be smoothly reciprocally rotated while surely adhering to the outer body frame, and leakage of viscous raw material can be surely prevented.

[0006]

[Operation] When the open end of the metering cylinder provided in the rotor is in communication with the position of the suction hole, the viscous raw material in the raw material supply hopper is suction-filled into the metering cylinder by the suction action of the piston, and then the rotor rotates 180 degrees. However, when the open end of the metering cylinder comes to the position of the filling hole, the viscous raw material inside is metered into the specified container from the filling hole by the discharging action of the piston, and the metering cylinder after filling is the reverse of the rotor. It is rotated again to the position of the suction hole to repeat the filling action, and the stroke of the piston is changed by adjusting the stroke adjustment mechanism of the piston to adjust the filling amount of the viscous raw material in the metering cylinder. It is something to do.

[0007]

Embodiments of the present invention will now be described with reference to the drawings.
A cylindrical outer casing 5 made of stainless steel, in which a suction hole 3 communicating with the raw material supply hopper 2 is provided in an upper portion of the filling machine base 1 and a filling hole 4 having the same diameter as that of the suction hole 3 is provided immediately below the suction hole 3, respectively. A cylindrical rotor 6 made of stainless steel having a peripheral surface formed of a high molecular weight polyethylene resin 6'having a molecular weight of 5.5 million or more is fitted and fitted so as to be supported and fixed and to rotate closely in the outer body frame 5. A rotary shaft 8 projecting from a drive casing 7 integrally fixed to the rear side of the rotor 6 is installed in the filling machine base 1 and is operated by an appropriate power rack and pinion mechanism 9 to rotate the rotor 6 at 180 degrees. It is configured to reciprocally rotate over a range.

In the rotor 6, there is provided a metering cylinder 10 having the same diameter as the metering cylinder 10 having an opening formed in the peripheral surface and reciprocally rotating between the suction hole 3 and the filling hole 4. The piston rod 12 of the piston 11 fitted in the cylinder 10 is connected to the operating rod 14 of the suction / exhaust device 13 such as an air cylinder installed in the drive casing 7, and the piston 11 is reciprocated to suck and exhaust the fixed amount cylinder 10. The operation rod 14 is provided with a stroke adjusting mechanism 16 for the piston 11 which is operated by a servomotor 15. On the other hand, below the filling hole 4, a tray transfer conveyor 18 having a tray stacking frame 17 at one end is provided and is configured to intermittently transfer the tray A to a position below the filling hole 4.

Since the present invention is constructed as described above, viscous raw materials such as mayonnaise, vegetables and other mixed salads are put into the raw material supply hopper 2 and the tray A is filled with the tray A by the tray transfer conveyor 18. When it is transported downward and stopped, the piston 11 of the metering cylinder 10 descends to suck and fill the viscous material in the material supply hopper 2 into the metering cylinder 10 through the suction hole 3, and then the rotating shaft 8 rotates the rotor 6 After rotating the opening of the filling cylinder 10 to the position of the filling hole 4 by reversing 180 °, the piston 11 pushes the viscous raw material and supplies the viscous raw material in a fixed amount from the filling hole 4 into the tray A. In order to reverse the above operation by reversing 180 degrees in the opposite direction and returning the metering cylinder 10 to the position of the suction hole 3 again, when changing the filling amount, the piston is used. 12 strokes is to adjust the stroke adjusting mechanism 16.

[0010]

As described above, according to the present invention, a suction port and a filling hole communicating with the raw material supply popper are provided in an outer casing which is provided in the vertical direction.
Since a rotor having a metering cylinder was provided so as to rotate by 0 degree, and the viscous material was supplied and metered into the container through the filling hole by a vertical suction / exhaust action of the piston of the metering cylinder, the metering of the viscous material was performed. The suction action into the cylinder and the filling action from the filling hole are performed smoothly, and the viscous raw material and its mixture do not remain or adhere to the metering cylinder or around the suction hole and the filling hole. A certain amount of viscous raw material can be smoothly and reliably filled in a tray or the like.

Further, since the rotor having the metering cylinder slides in close contact with the outer casing provided with the suction hole and the filling hole in the present invention, leakage of viscous raw material can be surely prevented, and a cover or the like is provided in the filling hole. It is hygienic as it can be filled without the need.
