Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a glassware crushing apparatus for crushing glassware such as fluorescent tubes to be disposed of.

[Conventional technology]

For example, in factories and offices that use many fluorescent tubes,
Disposal pits are generated on a daily basis, and the method of disposal is usually to set up a storage area and store them, and then take them out when the number is large and dispose of them.

[Question B that the invention seeks to solve] However, this disposal method has the problem of requiring a large space for storage compared to the number of fluorescent tubes. However, when transporting them, they often break and the broken pieces can easily cause injuries, which poses a safety problem. Furthermore, even if you try to increase the amount of fluorescent tubes stored in a regular collection box by simply crushing them, there is a risk that the pieces will fly out and cause accidental injury, and the degree of crushing will vary. Therefore, it was not satisfactory as a means for reducing space.

The present invention was created in view of this situation, and
The purpose is to provide a crushing device that can safely and reliably crush glass appliances such as fluorescent tubes that are no longer needed without storing them as they are, and that can effectively utilize space.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention provides a crushing chamber with an upper sealing plate and a lower sealing plate with a crushed material discharge port provided on the periphery, inside the device frame in which the raw material input tube is inserted through the upper surface. The crushing device has a crushing chamber in which a lower end opening of the input cylinder faces and a crushing mechanism, and a crushing material recovery mechanism in a lower part of the crushing chamber, wherein the crushing mechanism is , a first crushing mechanism using a rotating blade attached to the top of a vertical rotating shaft;
a second crushing mechanism consisting of a crushing claw fixed to the upper surface of the horizontal rotating shaft attached to the lower part of the vertical rotating shaft and a crushing claw fixed to the lower surface of the upper sealing plate; and a lower surface of the horizontal rotating plate. A glassware crushing device comprising a third crushing mechanism formed by a combination of a scraping plate fixed to the bottom and the lower sealing plate; A funnel-shaped diagonal descent guide member fixed to the diagonal descent guide member, a collection box placed below the diagonal descent guide member, and the collection box is placed on it, and the inclination is changed according to the weight of the collection box. The present invention proposes an apparatus for crushing glassware, which includes a sensor for detecting a predetermined inclination of the mounting plate.

Effect C] According to the present invention, when the vertical axis of rotation of the crushing chamber, and thus the rotary blades and the horizontal rotary plate are rotated, and raw material glassware is introduced from the input tube, the raw material is introduced into the crushing chamber and rotated. The crushed pieces are crushed by a first crushing mechanism consisting of rotating blades, and fall onto a horizontal rotating plate as coarsely crushed pieces. The coarsely crushed material on the horizontal rotary plate rolls toward the outer periphery due to the rotation of the rotary blades, the rotation of this horizontal rotary plate, and the centrifugal force based thereon, and the crushed material is rolled toward the outer periphery by the rotating crushing claws fixed to the upper surface of the rotary plate and the upper seal. A second blade consisting of a crushing claw fixed to a stop plate
The crushing mechanism crushes the material by pinching and pressing it, cutting it or crushing it. Then, while being crushed, it reaches the outer peripheral edge and spills onto the lower sealing plate. On the lower sealing plate, the crushed materials are scraped together by a rotating scraping plate fixed to a horizontal rotary plate.
It is discharged downward from the discharge port provided on the periphery of the lower sealing plate. This scraping plate also serves as a third crushing mechanism, and performs a crushing action such as crushing the crushed material sandwiched between it and the upper surface of the lower sealing plate during the sowing process, thereby further increasing the degree of crushing. The crushed materials that have fallen from the lower sealing plate in this manner are collected by a collection mechanism disposed below.

According to the collection mechanism of the present invention, the crushed materials that have fallen from the lower sealing plate are guided by the funnel-shaped oblique descending guide member, and
It will fall into a collection box placed further down. As debris accumulates in the collection box, the loading plate changes its inclination depending on its weight, but a sensor detects when the ITL plate reaches a predetermined inclination and issues a signal, allowing it to be placed at the appropriate weight. Collection boxes can be collected and exchanged for new collection boxes.

As the attached horizontal rotary plate 16 rotates, the dust collection mechanism 4 also starts.

In this state, when the fluorescent tube 22 is thrown into the charging tube 3 by pushing open the diaphragm 21, the fluorescent tube 22 enters the crushing chamber 12 from the lower end opening 3a of the loading tube 3, and the rotating blade of the first crushing mechanism 15, and fall onto the horizontal rotary plate 16 as relatively large coarse pieces. The coarse crushed pieces on the horizontal rotating plate 16 are rolled toward the outer periphery by the rotational force of the rotating blades 15, the rotation of the horizontal rotating plate 16, and the centrifugal force caused by this rotation, and in the process, the rotating crushed pieces The combination of the claw 17 and the crushing claw 19 fixed to the upper sealing plate lO, and the combination of these crushing claws 17.19 and the horizontal rotary plate 16
Alternatively, the second crushing mechanism in combination with the upper sealing plate 1O pinches, crushes, bends, or the like to crush the pieces into even smaller pieces. The crushed material that has passed through the second crushing mechanism in this way spills onto the lower sealing plate 11 through the gap between the outer peripheral edge of the horizontal rotary plate 16 and the cylindrical frame 9. The crushed materials on the lower sealing plate 11 are scraped together by the rotating scraping plate 18 of the third crushing mechanism, and fall through the notch 20 provided on the outer peripheral edge of the lower sealing plate 11. During this scraping process, the crushed materials are further removed from the lower sealing plate 11 and the scraping plate 1.
