FIG. 5 is a sectional view of the shutter, and FIG. 6 is a process drawing showing the operation of the embodiment apparatus. The entire device of the present invention comprises a material storage tank 100, a shutter 200, a container operation device 300, and a control device 400, which are collectively mounted on a frame 500.

The material storage tank 100 includes a viscous material receiving portion 101, an upper storage tank 102, a conical tank 103, and a pressurizing chamber 104. These are assembled by an assembly method that can be easily disassembled and assembled, for example, a latch-type fixing device with a handle so that internal cleaning and other operations can be easily performed. In the conical tank 103, a scraping blade 105 that slides on the wall surface and a screw feeder 106 that pushes out the viscous material downward are installed. The scraping blade 105 and the screw feeder 106 are rotated around the vertical axis in opposite directions by the electric motors 107 and 108, respectively. Further, the situation inside the material storage tank 100 can be visually checked through the viewing window 109.

In the material storage tank 100, the conical tank 103 and the pressurizing chamber 104 are attached and fixed to the column 501 of the frame 500 by the brackets 502 and 503. An upper frame 504 provided on the top of the pillar 501 supports the scraping blade 105, the drive shaft of the screw feeder 106, the power transmission device, and the motors 107 and 108.

The pressurizing chamber 104 is attached to the lower end of the conical tank 103, and the vertical screw feeder 106 is located above the pressurizing chamber 104 and presses the viscous material into the pressurizing chamber 104 for pressurization. .. There is a shutter 200 at the lower end of the pressure chamber 104. As shown in FIGS. 3 to 5, the shutter 200 includes a movable shutter plate 202 that slides back and forth in the guide 201. The rod 204 of the cylinder 203 (see FIG. 1) is pin-connected to the ear 207 of the movable shutter plate 202 via the shackle 205 and the pin 206.

The movable shutter plate 202 has a built-in piston 210 that is closely attached to a seal member 110 attached to the lower end of the pressurizing chamber 104. On the upper surface of the piston 210, a resin sealing material 211 that comes into contact with the sealing member 110 is attached to the piston body 214 by a pressing plate 212 and screws 213. Further, the piston 210 is fitted in the movable shutter plate 202 by fitting an O-ring 215, and the lower surface of the piston 210 forms a compressed air chamber 216. Further, the piston 210 is biased by a biasing spring 217 so as to be pulled downward.

As shown in FIG. 4, when the movable shutter plate 202 is retracted to open the lower end of the pressurizing chamber 104, the piston 210 is pulled by the urging spring 217 and the inside of the movable shutter plate 202 is pulled. The shutter 200 can be easily opened. When the shutter is closed, the viscous material is cut by the knife edge 218 on the front end side of the movable shutter plate 202 to proceed, and when the shutter is closed, compressed air is sent to the pressure chamber 216 to seal the lower end of the pressure chamber. The member 110 and the resin sealing material 211 are pressed against each other. As the resin sealing material 211, for example, a fluororesin can be used. The pressure bonding described above completely prevents leakage from the pressure chamber 104. After that, the viscous material is pressed into the pressurizing chamber 104 by the screw feeder 106.

The container operating device 300 conveys the tray filled with the viscous material to the lower side of the pressure chamber 104, holds the tray under the pressure chamber during the filling of the viscous material, and after the filling, moves the tray to the next step. It is a device to carry out. The tray is a container filled with viscous material, and has a box shape with an open top. As shown in FIG. 2, the container operation device 300 includes a carry-in belt 301, a stopper 306, a push-up device 310, and a carry-out belt 304. The carry-in belt 301 is a belt conveyer for carrying trays, and is composed of a large number of narrow belts arranged in parallel at intervals (see FIG. 1). The carry-in belt is driven by a motor 302 via a large number of head sheaves 303 arranged in parallel. The tail pulley of the carry-out belt 304 shares a shaft with the head sheave 303, and the tail pulley is rotatably fitted on the shaft of the head sheave 303 at a portion where it is spaced. Therefore, the carry-in belt 301 and the carry-out belt 304 can be operated and stopped independently. The tray that has been carried on the conveyor is stopped immediately below the pressure chamber 104 by the stopper 306.

The push-up device 310 pushes up the tray by the reciprocating cylinder 311, and pushes it against the lower end of the pressure chamber. The push-up part of the push-up device is a large number of vertical rods, which rises from the gap of the carry-out belt 304 and does not hinder the carrying of the carry-out belt. The frame 500 integrally supports the above devices. In the frame 500, a main pillar 501 is erected from a base frame 510. The base frame 510 includes wheels 511 and can move the entire apparatus. In addition, a positioning device 512 such as a screw jack that is fixed to the floor can be provided and fixed at a fixed position. A support frame 520 of the container operating device 300 is fixed to the base frame 510. Brackets 502 and 503 are attached to the side surfaces of the main pillar 501, and a horizontal frame 504 is attached to the upper end thereof. The brackets 502 and 503 and the horizontal frame 504 are used to mount the material storage tank 100, the shutter 200, and their attached devices in a well-balanced manner. Further, the overall control device 400 is also attached to this main pillar 501.

The operation of the apparatus according to the embodiment of the present invention will be described with reference to the sequence diagram of FIG. The viscous material is pressure-filled from the material storage tank 103 into the pressurizing chamber 104 by the downward screw feeder 106. The shutter 200 closes the lower end of the pressurizing chamber 104, compressed air is supplied to the compressed air chamber 216, and the piston 210 is pressure-bonded to the lower end seal member 110 of the pressurizing chamber 104 to lower the lower end of the pressurizing chamber 104. Is tightly sealed. In this state, the carry-in conveyor 301 carries the tray. The tray is stopped by a stopper 306 just below the pressure chamber.

As shown in FIG. 6, when the arrival of the tray is confirmed by a photoelectric tube or the like, the tray carrier, that is, the carry-in belt 301 and the carry-out belt 304 are stopped. Then open the shutter. That is, first, the compressed air in the pressure chamber 216 is discharged, the piston 210 is pushed down by the biasing spring 217, the seal at the lower end of the pressure chamber 104 is released, and the shutter plate is pulled out by the cylinder 203. At the same time when the shutter is opened, the push-up device 310 pushes up the tray to the lower end of the pressure chamber. Lower the stopper. The screw of the screen feeder 106 is rotated to fill the material in the pressure chamber 104 into the tray. Then, the shutter 200 is closed. At this time, the knife edge 218 at the tip of the shutter plate 202 cuts the viscous material. When the closed shutter 200 reaches the closed position, compressed air is supplied into the pressure chamber 216 to seal the lower end of the pressure chamber 104 with the piston upper surface. After sealing, the screw feeder 106 fills the material into the pressure chamber 104.

The carry-out belt 304 starts operation and carries out the tray. When the tray advances beyond the position of the stopper 306, the stopper 306 moves up and stops the tray that is next loaded. The above sequence is controlled by the control device 400. It is also possible to change the settings of sequence control contents depending on the type of material, type of tray, size, etc. In the embodiment of the present invention, it is possible to automatically fill the tray with the viscous material without leakage of the viscous material without using a complicated mechanism as in the past.
