Description

Description BACKGROUND OF THE INVENTION [0001] The present invention relates to a load cell.
It relates to a weight type filling device that fills while measuring the weight.
Cannot be transported independently, such as a syringe
It relates to a weight-type filling device that fills efficient containers.
is there. 2. Description of the Related Art A self-contained transfer device such as a syringe can be used.
When filling a container with a liquid,
Contained in a container holder called a carrier, transported and filled
Perform Japanese Patent Application Laid-Open No. 8-168528 discloses such a method.
An apparatus for filling a syringe with a drug solution is disclosed. this
In the device, the syringe 1 is in an upright state, that is,
Lower the needle mounting port 1b with the top cap stoppered
The opening side 1c of the large-diameter cylindrical portion 1a of the main body faces upward.
In a state where the carrier has been set,
And supply it to the filling machine 44. In the filling machine 44,
Upper opening of syringe 1 held by carrier 40
1c, a filling nozzle is inserted, and the medicine is inserted into the syringe 1.
Inject the liquid. [0003] As described above, a syringe or the like is placed in a carrier.
In a configuration in which the container is accommodated and transported, the syringe is placed inside the carrier.
Device to remove the syringe from the device
Requires a complicated structure and high cost.
is there. After the filling is completed, the syringe
The rear must be returned to the syringe insertion part side again
So you have to provide a conveyor for carrier return
Instead, a large space is required. In addition,
In such a filling machine, many containers are continuously transported and filled.
Need to prepare a large number of carriers.
And all these carriers must be sterile.
Work efficiency is low and costs are high.
is there. Therefore, containers can be transported and filled without using a carrier.
It is preferred to do so. [0004] Without using a carrier, such as a syringe
As a method of transporting and filling containers that cannot stand alone,
A so-called neck transfer is performed. For example, a syringe
Is formed on the plunger rod insertion side
Carry with the flange suspended from below and suspended.
Now. With such a neck transfer, the load cell causes
When performing heavy filling while measuring the amount,
Next, we will hook the neck (flange) of the syringe
The load cell is connected to the guide. [0005] As mentioned above, as described above,
Connect the load cell to the neck guide that holds the container
Configuration, each row corresponds to each neck guide.
The problem of high cost due to the need to provide
Yes, and the neck guide and load cell are integrated
In this case, another device such as a capper is installed in the filling machine.
It was impossible to see. The present invention has been made to eliminate the above disadvantages.
Transport containers without using a carrier, and
Dosing is only provided at the filling station to perform weight filling.
The purpose of which is to provide a gravimetric filling device
It is assumed that. [0007] Gravity filling according to the present invention.
The device has a support for supporting the container and rotates intermittently.
And a wheel arranged on the outer peripheral side of the wheel.
An outer peripheral guide that supports the container together with the
At the filling station in the rotation path of the wheel.
Filling nozzle and the load provided below the filling nozzle
A cell, a container holding member connected to the load cell,
Relative to the wheel and the outer circumference guide and the load cell
Lifting means for raising and lowering the wheel, the wheel and the outer peripheral guide
Opening and closing means for opening and closing the container, and
When the wheel reaches the filling station,
Lower the outer peripheral guide or load cell.
To lift and open the wheel and outer circumference guide
Filling with the container held by the holding member
This is what we did. [0008] In the above-mentioned weight type filling device, a container is supported.
When the wheel reaches the filling station and stops,
Wheel and the outer circumference guide on the opposite side
Or when the load cell rises,
The container is held in the connected container holding member. Further
Then, release the container by opening the wheel and the outer periphery guide. This
Fill the container with the filling nozzle in the condition of
You. The load cell is only provided at the filling station
In other areas, devices with different configurations such as cappers are used.
It can also be provided. When filling, the container
