A bag outer surface cleaning apparatus characterized by being configured to circulate.

According to the first aspect of the present invention, since the pressurized gas circulates in the gas cleaning processing container, the pressure injection device is simplified, the energy efficiency is remarkably improved, and the dust is reduced by the rotating brush. The removal efficiency is increased, and the above problem can be solved suitably. In addition, since the dust collectors are independently installed on the upper and lower sides, there is an effect that no turbulent flow is generated in the gas cleaning processing container, the wind phase flow is stabilized, and no dust is generated. Further, since the gas is circulated in the gas cleaning processing container, the pressure in the gas cleaning processing container does not go in the negative pressure direction,
Bacteria, pests and the like hardly penetrate through gaps and are suitable for HACCP. In the case of injecting the pressurized gas toward the bag, various modes are conceivable, but it is preferable to inject air from above, below, left and right of the bag, and it is preferable to inject air near the rotating brush.

Next, the operation of the sack cleaner 1 of the present embodiment will be described. The sack cleaner 1 is installed and used in a raw material loading line such as a flour mill, for example, in a pre-process such as a bag opening device, or in a process before shipping. Here, a case will be described where the bags S shipped from the factory are accepted as raw materials in a processing factory such as a baking / milling factory. First,
When a bag S conveyed from a carry-in section such as a truck or a wagon by a belt conveyor 18 or the like is carried into the air cleaning processing chamber 2 from the bag entrance 3 of the sack cleaner 1, the bag detection sensor 16 detects the bag S. Upon detection, a start signal is output to the control unit 20.

When the bag transport device 5 starts the transport operation of the bags S, the upper cleaning brush 610 and the side cleaning brushes 620, 6
30, and the lower cleaning brush 640 begins to rotate. The dust adhered to the left and right sides of the bag S is removed by the rotation of the side cleaning brushes 620 and 630 provided on the left and right of the bag S conveyed by the bag conveying device 5. The dust adhering to the bottom surface of the bag S is wiped off by the lower cleaning brush 640 provided in 57, and the dust adhering to the upper surface of the bag S is wiped off by the upper cleaning brush 610. The upper cleaning brush 610 swings in a swinging manner, and rotates upward when the bag S is conveyed,
It moves up and down while following the surface of the bag S, and when the bag S passes,
It rotates downward and contacts the lower cleaning brush 640. The beater bar 615 swings integrally with the upper cleaning brush 610. Hitting the rotating upper cleaning brush 610 to brush 61
Remove dust from zero. Flap 624, 634, 64
3 also removes dust from the rotating brushes 620 to 640 by hitting each of the brushes.

Air is injected from the upper pressure air injection device 7 and the lower pressure air injection device 8 to the outer surface of the bag S to directly remove dust from the outer surface of the bag S,
Dust removal is assisted by air injection to 640 to increase the efficiency of dust removal from brushes 610-640. The main purpose of the air injection is to assist the dust removal of the brushes 610 to 640, and the direct removal of the dust by the air injection is secondary. However, if the air pressure is set to a high pressure, the air cleaning can be made stronger.

In the lower and upper portions of the air cleaning processing chamber 2, dust-containing operation is performed by the lower dust collector 11 and the upper dust collector 10, and the dust-containing air is sucked in, the dust is adsorbed and removed by the filter cloths 103 and 113, and the clean air is removed. Are circulated to the upper pressure air injection device 7 and the lower pressure air injection device 8 via the upper circulation passage 12 and the lower circulation passage 13, respectively.

When the bag S being transported on the upper surface of the bag transport device 5 completely passes through the gap between the lower cleaning brush 640 and the upper cleaning brush 610, the cleaning of the bag S is completed and the air cleaning processing chamber 2 is closed. It is carried out to the bag outlet 4 from the inside. With this cleaning operation, the dust removed by the side cleaning brushes 620 and 630, the lower cleaning brush 640, and the upper cleaning brush 610 is sucked by the dust collection operation of the lower dust collector 11 and the upper dust collector 10, and the air cleaning processing chamber. The inside of 2 will be kept clean. Bag S unloaded from sack cleaner 1
Is conveyed to the next step (opening device or the like) by the belt conveyor 19.

As described above, according to the sack cleaner 1 of the present embodiment, the following effects are obtained. (1) The cleaning process of the bag S is performed by combining three types of brushes of the upper cleaning brush 610, the side cleaning brushes 620 and 630, and the lower cleaning brush 640 that rotate at high speed. Pressure air injection device 7, lower pressure air injection device 8, side pressure air injection device 9
Accordingly, dust is efficiently collected by the air circulation flow generated by air injection from above, below, left and right. Therefore, the brush cleaning and the air cleaning process can be completed in a short time, and the working efficiency is dramatically improved. In addition, since the powder adhering to the surface of the bag S can be removed by the strong cleaning power of the circulating air and the high-speed rotating brush, the cleaning performance is further enhanced. In particular, it is most suitable for cleaning the bags S before shipment from a factory or before being carried into a clean area at a HACCP management factory. (2) Since the upper dust collector 10 and the lower dust collector 11 are installed independently of each other vertically, the wind current phase due to the dust collecting operation is stabilized. As a result, turbulence can be prevented from being generated inside the air cleaning processing container 1a, and the air cleaning processing container 1a can be prevented.
There is no powder accumulation inside. (3) Since the upper dust collector 10 and the lower dust collector 11 are integrated inside the air cleaning container 1a, an external auxiliary device such as a suction duct is not required, and the size of the device can be reduced. (4) The control unit 20 is connected to the air cleaning container
The need to separately install a control panel or the like in the factory is eliminated by integrally providing the control panel inside. (5) The provision of the large inspection doors 108 and 118 on the front surface of the air cleaning container 1a facilitates maintenance such as replacement of the filter cloth. (6) By making the entire device compact and simple in shape and structure, the device itself can be kept clean and the work environment can be made cleaner. In addition, there is little adhesion or remaining of powder particles on the exterior panel surface or inside of the air cleaning container 1a of the apparatus, and the apparatus can be easily cleaned. Further, the installation area in a factory or the like can be greatly reduced as compared with the conventional apparatus. As a result, it is possible to introduce and install the system in a small-scale flour mill, etc., and to realize a significant cost reduction in all aspects.

It should be noted that the present invention is not limited to the above-described embodiments or embodiments, but may be modified without departing from the technical idea of the present invention. Such modifications and equivalents are also included in the technical scope of the present invention.
