Description

[Detailed description of the invention] <Industrial application field> The present invention mixes dirty pachinko balls into abrasive grains,
When polishing is carried out using a lift pipe with a spiral body inside, the powder of abrasive particles and other dust generated when the abrasive particles and pachinko balls rub against each other in the lift pipe are removed. A process in which a dust suction section is provided in a sorting device installed on the upper side of the pipe, and the dust falling into the dust suction section is suctioned and collected via a suction gutter, and the abrasive grains are supplied to an uncleaned transport pipe. This invention relates to a pachinko ball transport device characterized in that it is possible to select between the following.

Conventionally, pachinko ball lifting equipment collects dirty pachinko balls at the bottom of a single upright lifting pipe, mixes abrasive particles into the dirty pachinko balls, and rotates the lifting spiral body to lift the balls. He was polishing pachinko balls.

In addition, there are polishing and lifting devices that curve upwards from a horizontally provided transfer pipe to form a lifting pipe, and lift the pipe in a single helical body through the pipe in horizontal transfer, and a horizontal transfer pipe and a lifting pipe. Polishing and lifting devices with separate spiral bodies installed on each pipe have also been proposed, but these devices do not have a device to remove dust when polishing pachinko balls, and they do not remove dust, oil from hands, etc. Since the pachinko balls are polished while adhering to the abrasive grains, dust and oil from hands adhere to the pachinko balls, resulting in staining the surface of the pachinko machine.

In addition, an abrasive particle cleaning device is separately provided to remove dirt from the abrasive particles separated by the culvert in the sorting device, so that the abrasive particles are constantly cleaned. Since there is no device to remove the dust that comes out, the dust that comes out of the abrasive grain cleaning device still adheres to the abrasive grains.

In order to eliminate the above-mentioned drawbacks, the present invention provides a dust suction section in an abrasive grain receiving tray provided with a gutter-like gutter for separating pachinko balls and abrasive grains, in a sorting device installed at the upper part of a lifting pipe. one end of a dust suction gutter is connected to the dust suction section, the other end of the dust suction gutter connects the dust storage chamber to an adjacent dust collection device, and the dust from the sorting device is sucked by power, Furthermore, the dust coming out of the abrasive particle washing device is also sucked in through the suction gutter, and the abrasive particles discharged from the abrasive particle tray can be supplied to the lifting pipe by making it possible to select between a process in which they are not cleaned and a process in which they are cleaned. It is.

Embodiments of the present invention will be described in detail below based on the drawings.

A suction hole 11b is drilled at the lower position where a is stretched, and one end of a dust suction gutter 13 is connected to the suction hole 11b.

The mixture of pachinko balls a and abrasive grains b, which are lifted through the lifting pipe 1 and sent out onto the screen gutter 9 in the sorting device 7, is separated by the screen gutter 9 described above, and the pachinko balls a are The abrasive particles b roll on the trough 9 of the screen and are supplied to the pachinko machine via the replenishment gutter 8, while the abrasive particles b fall into the abrasive particle tray 10 below. When the abrasive grains b are not contaminated, the first abrasive grain descending gutter 1 whose one end is connected to the abrasive grain receiver 10
2' into the abrasive grain storage tank 19, and then fall into the horizontal transfer pipe 2. However, abrasive grain b
If the abrasive particle cleaning device 1 is contaminated, the abrasive particle cleaning device 1 is removed from the second abrasive particle descending gutter 12 by switching the switching valve 21.
7, and after being thoroughly cleaned, it enters the abrasive grain storage tank 19 via the delivery gutter 18, and is transferred to the horizontal transfer pipe 2.
It's starting to fall inwards.

Reference numeral 20 denotes a collection gutter into which the pachinko balls a that have gone around the inside of the pachinko machine and become dirty are collected and sent.

The present invention has the above configuration, and its operation will be explained next.

The abrasive grains b and pachinko balls a, which have been lifted in the transport pipe 1 by the transport spiral body 5, are sent out from the outlet 1a into the sorting device 7, and while sliding down on the child-like gutter 9 of the screen, the abrasive grains b. The pachinko balls a fall between the troughs 9 of the dust c basket and into the lower abrasive grain tray 10, and the pachinko balls a fall over the troughs 9 of the basket and are supplied from the supply gutter 8 into each pachinko machine.

Furthermore, the dust c that has fallen together with the abrasive grains b passes through the mesh plate 11a stretched over the top surface and falls into the box-shaped dust suction section 11, while the abrasive grains b slide down the mesh plate 11a and descend. The dust c that enters the opening 10′, descends through the second abrasive grain downspout 12 or the first abrasive grain downspout 12′, and falls into the dust suction section 11 is transferred to the dust suction gutter 13.
The dust is sucked into the dust collector 14 through the dust collector 14 and stored in the adjacent dust storage chamber 15.

On the other hand, the abrasive grains b that have fallen into the abrasive grain receiver 10
If the polishing ability decreases due to dirt, the switching valve 21
The abrasive grains are lowered into the second abrasive grain descending gutter 12, fed into the abrasive grain cleaning device 17, and after being sufficiently cleaned, are supplied into the horizontal transfer pipe 2 via the delivery gutter 18 and the abrasive grain storage tank 19.

Dust and dirt are sucked into the dust collector 14 through the dust suction gutter 13 and stored in the adjacent dust storage chamber 15.

Moreover, dirt, dust c, etc. discharged from the abrasive grain cleaning device 17 for removing dirt from the abrasive grains b are also collected through the suction gutter 16, thereby increasing the purification efficiency of the pachinko balls.

Further, according to the present invention, the abrasive grains discharged from the abrasive grain tray are supplied from the first abrasive grain down-ditch to the lifting pipe, and the abrasive grains are guided from the second abrasive grain down-trough to the cleaning device, cleaned, and then transported. Since the process for supplying the abrasive particles to the pipe can be selected, the abrasive particles can be thoroughly cleaned by operating the switching valve depending on when the abrasive particles become contaminated.For example, once a day or once every few days Pachinko balls can be efficiently polished and cleaned simply by introducing the abrasive grains into the cleaning device several times and cleaning the abrasive grains, and a lifting device with high practical value can be provided.
