Description

[Detailed Description of the Invention] The present invention relates to a batch type quantitative metering device that supplies a required amount of raw material from a feeder to a container.

Conventionally, in this type of apparatus, a weighing hopper is disposed between a feeder and the container, and it is common to supply exactly the required amount of raw material from the weighing hopper to the container. However, when a weighing hopper is provided in this way, the height of the entire device increases, and there is a risk of weighing errors due to raw materials adhering to the container without being discharged, or scattering of raw materials in the supply path from the weighing hopper to the container. There are drawbacks that occur.

Therefore, an object of the present invention is to provide a device that can guarantee sufficient weighing accuracy even when the weighing material is directly supplied to the container without using a weighing hopper, and can also reduce the height of the equipment.

The weighing device with an elevator of the present invention is arranged so as to be movable in the horizontal direction below the dispensing port of the feeder, and is arranged at a first interval in the horizontal direction to receive raw materials from the feeder. a container conveyance slider having a first container support arm that supports a pair of arms protruding laterally from the container from below; second container support arms arranged in the horizontal direction at intervals, the arm of the container supported by the first container support arm is supported from below by the second container support arm to lift the container; A lifting body is provided, a load cell is interposed between the lifting body and the second container support arm, and the amount of delivery from the feeder to the container is controlled based on a weight signal from the load cell. shall be.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

1, 2, and 3 are reservoir hoppers arranged in a horizontal row,
Reference numerals 4, 5, and 6 designate object feeders mounted on the bottoms of the reservoir hoppers 1 to 3, respectively, and are driven by motors 7, 8, and 9, respectively, to perform dispensing. Reference numeral 10 denotes a lateral movement device, which includes a feed screw 11 extending along the arrangement direction of the feeders 4, 5, and 6, and a lateral movement device 1 that is screwed onto the feed screw 11 and is movable in the horizontal direction.
It consists of a slider 12 as a base, and a pair of container support arms 13a, 13b extending from the slider 12 toward the feeders 4, 5, and 6.
2 is moved in the horizontal direction (in the direction of the arrow) by the feed screw 11 being driven by the motor 14. 15, 16, 17 correspond to the feeders 4 to 6, and the lateral movement device 10 is provided on the side of each feeder 4, 5, 6.
A vertical movement device disposed facing the vertical movement device includes a feed screw 18 extending in the vertical direction, an elevating body 19 screwed onto the feed screw 18 and movable in the vertical direction, and a vertical movement device disposed facing the elevating body 19. A pair of container support arms 20a, 20 extending toward the lateral movement device 10
Each elevating body 19 is moved in the vertical direction (in the direction of the arrow) by driving each feed screw 18 by a motor (not shown). Further, 21 is a container to which raw materials are supplied from the feeders 4, 5, and 6, and a pair of arms 22a, 22b are protruded from the sides. Reference numeral 23 denotes a vertical movement device for carrying in and out, which is arranged to face the horizontal movement device 10 together with the vertical movement devices 15, 16, 17, and its configuration is the same as that of the vertical movement devices 15, 16, 17, but the feeding The screw 18' is longer than the lead screw 18. Note that here, the container support arms 13a, 1 of the lateral movement device 10
The spacing L ₁ of the containers 3b is larger than the width L ₀ of the container 21,
Container support arms 20a, 20b of the vertical movement devices 15, 16, 17 and the vertical movement device 23 for loading and unloading,
The distance _L2 between 20'a and 20'b is larger than the distance _L1 . Further, each container support arm 20a, 20b of the vertical movement devices 15, 16, 17 is attached to the elevating body 19 via a load cell 24, respectively.

With this configuration, the slider 12 of the horizontal movement device 10 is moved to the position of the vertical movement device 23 for loading/unloading, and the vertical moving device 23 for loading/unloading supports the container 21 with the container support arms 20'a, 20'b. When the elevating body 19' is lowered from above to the bottom, when the container support arms 20'a and 20'b pass the container support arms 13a and 13b of the lateral movement device 10, the container 21 is moved to the side of the lateral movement device 10. Transfer to. After the elevating body 19' is sufficiently lowered, the slider 12 is moved to the position of one of the feeders 4, 5, and 6 for the raw material to be supplied. At this time, the necessary elevating bodies 19 of the vertical moving devices 15, 16, and 17 have been lowered to a position where they do not collide with the container 21 moving together with the slider 12, and the slider 12 is, for example, as shown in FIG. When the feeder 4 reaches the desired position, the vertical moving device 1
The elevating body 19 of No. 5 is raised. As a result, when the container support arms 20a, 20b of the elevating body 19 pass the container support arms 13a, 13b of the lateral movement device 10, the container 21 is transferred to the vertical movement device 15 side. The elevation of the elevating body 19 of the vertical movement device 15 is as follows:
The raw material receiving port 25 of the supported container 21 continues to a predetermined position corresponding to the dispensing port 26 of the feeder 4.
After that, when the raw material is discharged from the feeder 4, the discharged raw material is transferred to the lifting body 19 through the load cell 2.
Container 21 supported by the container support arms 20a, 20b attached via 4, 24
be thrown inside. As the raw materials are supplied, the load acting on the load cells 24, 24 increases. Therefore,
The control device (not shown) of the feeder 4 is the load cell 2
It is detected from the outputs 4 and 24 that the necessary amount of raw material has been supplied, and the dispensing is completed. Then, the container 21 that has been supplied with the necessary amount of raw materials is carried out along a route opposite to the carrying-in route. If a reservoir hopper with a metered feeder attached to the bottom and a lateral moving body are placed above the reservoir hopper, the amount of multiple metered feeders into containers can be dispensed with one weighing device with an elevator. can also be controlled. The same applies even if the reservoir hopper is a rotating body such as a mixer.

As explained above, according to the weighing device with an elevator of the present invention, during the feeding of raw materials from the feeder into the container, the container is supported from the side by the second container support arm; By inserting a load cell between the support arm and the lifting body, raw materials can be put into the container while weighing the input amount, without the need for a conventional weighing hopper between the feeder and the container. Able to perform accurate weighing. Furthermore, by interposing the load cell between the second container support arm and the elevating body,
The height of the equipment can be lowered compared to the case where a weighing device or the like is provided below the container, and in addition to eliminating the need for a weighing hopper, the height of the equipment can be made sufficiently low.
