Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a content discharging device that regularly and automatically discharges contents that have been efficiently stirred and mixed by a stirring drum from the stirring drum.

Conventionally, in a stirring device equipped with a bottomed cylindrical stirring drum that stirs and mixes two or more types of powder materials while rotating, when taking out the contents from the stirring drum, the stirring drum is tilted and the outlet is opened. After facing downward, the lid of the outlet was removed and the contents were discharged into a storage container placed below the outlet. At this time, since the stirring drum is inclined, the contents are rapidly dropped and discharged from the outlet into the storage container while pulsating. It was difficult to carry out the discharge work smoothly because of the powder that flew up and became cloudy. Especially if the contents are metal powder or resin powder,
Inhaling this powder could cause health problems, so it was necessary for workers to remove the floating powder using a dust collector and to wear protective masks. In addition, since most of the contents in the stirring drum are quickly discharged from the outlet, a large storage container must be prepared to prevent the contents from scattering, which requires time and effort to handle and install. It is expensive and uneconomical, and the contents inside the storage container are transferred each time into 18 cans or 10 to 20 kg bags to be provided to the customer, so processing the contents is labor-intensive. It was not only time-consuming, but also very time-consuming and troublesome.

The present invention eliminates the above-mentioned drawbacks by attaching and detaching an adapter for discharging contents to the outlet of the stirring drum in a single motion, and discharging the contents uniformly without pulsating. In addition to eliminating the harmful effects of the contents flying up, the contents in the stirring device can be quickly and easily packed into small cans or bags for direct delivery without using large storage containers.

Next, to explain the operation, when mixing two or more types of powder materials, when the materials are stored in the stirring drum 21 and the electric motors 10 and 20 are started, the stirring drum 21 is rotated by the friction wheel 8. At the same time, the material in the stirring drum 21 is stirred and mixed by the scraping plate 23 by swinging back and forth about the support shafts 2 and 2' via the base plate 1 by the crank mechanism A. When taking out the stirred and mixed contents from the stirring drum 21, after tilting the stirring drum 21 with the crank mechanism A so that the entrance/exit port 25 faces upward, the locking plate 32 of the opening/closing lid 29 is inserted into the locking metal fitting 36. The opening/closing lid 29 is removed from the lid body 24 by rotating it in the opposite direction to the stopper 35 and separating the locking piece 33 from the locking portion 34. After that, the gasket 42 provided on the cover 39 of the discharge tube 38 is pressed against the gasket holder 28 provided on the outer periphery of the entrance/exit port 25, and the locking member 40 is held on the locking metal fitting 3 by the handle 46.
6 until it comes into contact with the stopper 35, and the discharge tube 38 is attached to the entrance/exit 25 of the lid body 24 using the cover 39. Furthermore, the discharge pipe 3
A cylindrical cloth guide 48 is removably attached to the tip of 8 with a string or the like. After installing the discharge tube 38 as described above, squeeze the lower end of the guide 48 by hand to move the stirring drum 21 to the crank mechanism A.
When the inlet/outlet 25 is slightly inclined so that the inlet/outlet 25 faces downward, and the lower end of the guide 48 is placed in, for example, an 18 can and the restriction is released, the contents in the stirring drum 21 will flow from the outlet 25 to the discharge tube 38-. It passes through the guide 48 and is discharged into the can body 49. At this time, the contents are transferred from the large-diameter stirring drum 21 to the small-diameter discharge tube 38.
Since the contents are discharged through the can body 49, the discharge speed of the contents is slowed and the amount of discharge is suppressed, so that the contents are discharged into the can body 49 in an orderly manner while being surrounded by the guide 48. After a certain amount of the contents have been discharged into the can body 49, the lower end of the guide 48 is once squeezed to stop the discharge, and the lower end of the guide 48 is inserted into the next can body and the contents are discharged in the same manner as described above. conduct. If the discharge speed decreases significantly, the inclination angle of the stirring drum 21 is gradually increased by the crank mechanism A, and the stirring drum 21 itself is rotated. Therefore, the contents are scraped up by the discharge guide plate 27 disposed on the inner surface of the lid 24 and are sequentially sent to the discharge tube 38 and discharged from the guide 48 into the can body. In this case, the contents will be removed from the discharge guide plate 27.
The particles are scraped up and try to scatter in the radial direction from the entrance/exit 25, but they are caught by the discharge pipe 38 attached to the entrance/exit 25 and are discharged into the can body through the discharge pipe 38 without scattering to the outside. .
Also, the guide 48 tries to spring up from inside the can body 49 due to the rotation of the stirring drum 21, but the guide 48
When the contents are passing through the guide 48, the guide 48 only rotates around its axis in a slightly twisted state and does not jump up, so that the contents can be discharged without scattering to the outside. I can do it. In this way, the stirring drum 21 is tilted at a required angle and rotated to sequentially discharge the contents through the discharge pipe 38 and the guide 48 into the can body 49 for delivery, and when the can body 48 is full. Stop the rotation of the stirring drum 21, and also squeeze the lower end of the guide 48 to temporarily stop the discharge, prepare the next empty can, and once the contents have been completely discharged again,
After putting in the next mixed material with the inlet/outlet 25 of the stirring drum 21 facing upward, open/close the opening/closing lid 29 of the inlet/outlet 25.
Close the container and stir and mix again.

Next, when cleaning the inside of the stirring drum 21, the locking tool 26 is loosened, the lid body 24 is removed from the stirring drum 21, and the inside is cleaned. At this time, the lid body 24, the opening/closing lid 2
9. The adapters 37 may be cleaned individually.

As mentioned above, in this invention, a hollow conical lid with an opening for the entrance and exit of the contents at the top is removably attached to the opening surface of the stirring drum, and the lid is attached to the outer surface of the drum with the entrance and exit port sandwiched therebetween. A stopper is attached, and a discharge guide plate is arranged on the inner surface facing the entrance and exit, and at the entrance and exit of the lid, there is a container for discharging contents, which is equipped with a cover at one end of a horizontally long discharge tube. The adapter is removably attached using a locking member rotatably provided on the outer periphery of the discharge cylinder via a link, and the contents in the stirring drum are powdered using the above-mentioned discharge adapter. This system is designed to smoothly discharge the stirring drum without scattering it to the outside.Unlike conventional methods, when the lid of the stirring drum is removed, the contents pulsate and are rapidly discharged, causing powder from the contents to fly up. I stood there,
This is completely different from the original, which requires a large storage box to store it.In this case, a hollow conical lid is attached to the opening surface of the stirring drum, and the entrance and exit opening at the top of the lid has a horizontally long By attaching the long cylindrical adapter, it becomes as if a funnel is attached to the opening surface of the stirring drum, so the flow rate of the contents inside the stirring drum is significantly weakened by the lid and the horizontally long adapter. Since the content can be discharged from the adapter at a uniform speed, it is possible to significantly reduce the flying up of powder from the contents during discharge, making it possible to perform the discharge operation smoothly, and also to reduce the discharge speed. By lowering and uniformizing the content, it is possible to pack the contents into small cans for shipping from the beginning, without having to store them in large storage containers.
In addition, the adapter for discharging contents has a diameter smaller than the diameter of the entrance and exit of the lid body, so in addition to the fact that the lid body is formed in a hollow cone shape, the contents can be rapidly discharged from the stirring drum. As a result of the fact that the contents to be removed are significantly suppressed from being discharged, it is possible to always discharge the contents in an appropriate amount and smoothly from the adapter. Furthermore, the discharge adapter has a lid provided at one end of the adapter that is attached to the contents entrance/exit of the lid that covers the opening surface of the stirring drum using a locking member in the same way as the opening/closing lid that opens and closes this entrance. Since it can be attached and detached with a single motion, it is possible to quickly and easily discharge the contents. In addition, since the contents are discharged with the stirring drum formed into a funnel by the discharge adapter and the lid, some of the contents tend to remain inside the stirring drum, but this proposal does not require the use of the lid. The discharge guide plate installed on the inner surface of the body uses the rotation of the stirring drum to scrape up the contents and discharge them to the adapter, making it possible to completely and easily discharge the contents inside the stirring drum. I can do it. Moreover, since the discharge adapter, the lid body, and the opening/closing lid can be attached and detached individually, they can be easily washed with water, and their management and storage can be carried out hygienically. Furthermore, by using a cylindrical cloth guide in the discharge adapter, scattering and flying up of powder can be significantly suppressed, and the discharge device of the present invention can perform discharge operations safely and smoothly. Of course, the device itself has a simple configuration, can be manufactured at low cost, and has many excellent practical effects.
