Description

  The present invention relates to a spray can simple treatment apparatus for safely removing residual contents (liquid matter, gas) of used spray cans (aerosol cans) such as insecticides, deodorants, and cosmetics.

  Used spray cans (aerosol cans) for insecticides, deodorants, cosmetics, etc. are discarded when they are used, but some of them are discarded with some gas or liquid remaining inside, and incinerated as they are Or compression treatment may cause explosion or rupture. Therefore, conventionally, the cans are physically punched one by one to release the residual gas (flammable gas such as LPG) in the can to the atmosphere, and the residual liquid (ethanol etc.) is appropriately treated. is the current situation. However, in general, the work of drilling holes in used spray cans is complicated, and the work environment is not only bad due to the scattering of liquids and gases, but also health problems, as well as accidents such as ignition and explosions. Could occur.

  Therefore, conventionally, various devices for automatically making a hole in a used spray can have been proposed (Patent Documents 1 to 3). Among these, the ones described in Patent Documents 1 and 2 are systems in which the spray can is laid sideways and punched with a perforating pin from the top, and the one described in Patent Document 3 is lower than the spray can that is laid sideways. This is a method of drilling with a drill pin.

  However, among the conventional spray can drilling devices described above, the one that lays the spray can on its side and punches it with a punch pin from the top, the residual gas or residual liquid material blows upward at the time of drilling, and the surrounding environment deteriorates. There is a problem that the risk of ignition / explosion of scattered gas cannot be avoided. On the other hand, in the case of a method that pierces with a piercing pin from the bottom to a spray can that has been laid down, residual gas and residual liquid in the can are ejected downward at the same time as piercing, and the ejected liquid is recovered below the spray can Although it is possible, there is a problem that deterioration of the surrounding environment due to scattering of the ejected gas cannot be avoided because there is no means for collecting the ejected gas without scattering it around.

  The present invention has been made in view of the above-mentioned problems, and prevents the scattering of residual gas and residual liquid material during drilling, can significantly improve the working environment, and is free from the risk of gas ignition and explosion. It is an object of the present invention to provide a spray can simple processing apparatus that can sufficiently ensure the safety of the spray can.

  The spray can simplified processing apparatus according to the present invention can automatically pierce the bottom surface of the can without the leakage and scattering of the residual liquid material and gas inside the used spray can standing upright. In addition, it has the function of separating the residual liquid and residual gas in a sealed state and collecting them separately outside the can. Spray can holding unit comprising a vertical cylindrical body that is elastically supported, spray can pressing mechanism comprising a fluid pressure cylinder that presses the spray can vertically held by the spray can holding unit downward, and the spray can A spline that is slidably fitted to the vertical cylindrical body of the holding part and is held vertically to the spray can holding part by a wedge-shaped sharp part formed in a wedge shape in cross section at the tip part. -A spray can piercing mechanism comprising a cylindrical piercing needle that pierces the bottom of the can from below, and a residual liquid substance and a residue that are provided below the cylindrical piercing needle and flow down inside the cylindrical piercing needle. A sealed liquid material / gas receiving portion for receiving gas, a container for collecting the liquid material in the sealed liquid / gas receiving portion, and an exhaust device for sucking and releasing the gas It is.

Further, the spray can piercing mechanism of the device of the present invention has a can mounting table for holding the used spray can vertically at the top, and the cylindrical piercing needles are slidably inserted inside. A vertical cylindrical body is elastically supported in a bottomed support outer cylinder fixed perpendicularly to the machine base so as to be movable back and forth by a spring, and a lower end portion of the cylindrical perforation needle is a bottom portion of the support outer cylinder The structure is provided with a spray can pressing mechanism comprising a fluid pressure cylinder that presses a spray can placed on the can mounting table from above to a support column that is supported through the base and fixed to the machine base.

It is externally fixed to the flange, and the It is an preferred embodiment that forms a structure in which the sealing member is provided on the inner surface of the di-section.
An air cylinder or a hydraulic cylinder can be used as the fluid pressure cylinder of the spray can pressing mechanism, and a suction fan or a vacuum pump can be used as the residual gas exhaust device.

  The spray can simplified processing apparatus of the present invention automatically punches the bottom surface of the can in a substantially airtight state by pressing the can with a fluid pressure cylinder in a state where the used spray can is set up vertically. The residual liquid and residual gas inside the can flowing out from the hole are taken out from the can in a sealed state, the residual liquid is collected in a container, and the residual gas is sucked and exhausted to the atmosphere. The residual liquid and residual gas are not leaked or scattered to the surroundings, so that the working environment can be remarkably improved, and there is no risk of gas ignition / explosion, so that the safety of the processing work can be sufficiently secured. In addition, since the fluid pressure cylinder for drilling in the device of the present invention and the exhaust device such as a suction fan and a vacuum pump can be controlled by button operation, a used spray can can be set on the device and the button operated only at the site. Work is completed, and disposal of used spray cans can be simplified and speeded up, and operator fatigue can be reduced.
