Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention is used in the field of crushing glass tubes for fluorescent lamps and the like discarded from households.

(b) Prior art In general, in order to make crushing equipment such as fluorescent lamps smaller and cheaper to manufacture, the input chute is tilted forward and downward and moved into the casing by the weight of the fluorescent lamp. I'm starting to let them do it.

However, the length of the fluorescent lamps may be short for home use or long for commercial use, so if the feeding chute is lengthened so that it can be used with either type of fluorescent lamp, the feeding position The height above the ground becomes very high, which reduces the work efficiency for charging, and if it is shortened, a part of the long fluorescent lamp will be exposed from the chute, and there is a risk that the fluorescent lamp will fly out during crushing.

(c) Problems to be Solved by the Invention The present invention solves the above-mentioned problems by connecting a swinging chute that can swing up and down to the inlet of the casing, and connecting an extension chute that can rotate to the swinging chute. The length of the chute can be adjusted according to the length of the fluorescent lamp, and the loading position can be adjusted by swinging it up and down.

(d) Means for Solving the Problems The present invention provides a crushing device such as a fluorescent lamp, which has an input port at the top and a discharge port at the bottom of a casing in which a crusher is installed. A crushing device such as a fluorescent lamp, which is formed by connecting a rocking chute that is swingably supported, and further connecting an extension chute that is rotatably supported to the end of the rocking chute. The invention relates to a charging device.

(e) Example The following example will be explained using drawings. 1 is a trolley 2
A casing provided above.

An input port 3 is provided in the upper part of the casing 1, and an input device 5 for guiding the fluorescent lamp 4 into the casing 1 is provided opposite the input port 3. The loading device 5 has one end of a swinging chute 6 communicated with the charging port 3 attached to the edge of the charging port 3 via a bracket 7 so as to be able to swing vertically. The other end of a pivoted spring tube 8 is pivoted, and the spring tube 8 allows the swinging chute 6 to be swung up and down with a slight input.

Further, a swing chute 10 is connected to the swing chute 6 via a bracket 9, and when the extension chute 10 is moved up and down, the swing chute 6
It can be stored above, and when rotated downward, it forms a long chute.

A bellows-type cover 11 is provided at the connection portion between the input port 3 side and the swinging chute 6, since the gap becomes wider when the swinging chute 6 swings.
In addition, a lid 1 is provided at the end of each chute 6, 10 to prevent glass pieces from flying out when the fluorescent lamp 4 is shattered.
2 and 13 are provided.

A discharge port 14 is formed in the lower part of the casing 1, and the crushed glass pieces are transferred from the discharge port 14 to a drum 15, which will be described later.

Inside the casing 1, a first crusher 16 for coarse crushing is installed in the upper part, and a second crusher 16 for fine crushing is installed in the lower part.
A crusher 17 is provided.

The first crusher 16 includes a motor 1 that pivotally supports a crushing blade 18 in a swingable manner at a position facing the input port 3, and a part of the crushing blade 18 is provided outside the casing 1.
The arm 22 is connected to the link 21 which is passed through the slit 20 of the casing 1 to the arm 22.
The rotation of the crushing blade 18 causes the crushing blade 18 to swing, and the tip of the crushing blade 18 comes into contact with a holder 23 provided on an extension of the edge of the input port 3.

The second crusher 17 includes a pair of rollers 24, 2
4 are provided in parallel, and a plurality of protrusions 2 are provided on the surfaces of both rollers 24, 24 to improve the biting of glass pieces.
5... are provided, and these protrusions 25... come into contact with opposing rollers 24, 24.

Further, one roller 24 is rotated by a motor 26 outside the casing 1 to the opposite roller 24 side,
The other roller 24 is rotated toward the opposing roller 24 by frictional force with one roller 24 .

A transfer pipe 27 is connected to the discharge port 14,
The end of the transfer pipe 27 is connected to a cover 28, and the cover 28 is provided above the drum 15 placed on a handcart 29.

A blower 30 is attached to the cover 28, and this blower 30 sucks the air in the drum can 15, supplies this air through an air pipe 31 to a location opposite to the outlet 14 of the casing 1, and uses this air to It is designed to force-feed glass pieces.

32 is a guide for guiding the glass pieces crushed by the first crusher 16 to the second crusher 17.

33 is a filter provided in the blower 30.

The present invention has the above-mentioned structure, and the operation thereof will be explained next. First, the motors 19 and 26 are started to swing and rotate the crushing blade 18 and the rollers 24 and 24 in the direction of the arrow.

At that point, when processing a short fluorescent lamp, the swinging chute 6 and the spring tube 8 are tilted forward and downward with a slight amount of human power as shown by the solid line in FIG. 1, and the extension chute 10 is rotated upward. and store it on the swing chute 6.

In this state, the fluorescent lamp is inserted into the swinging chute 6. At this time, the height h above the ground at the loading position is such that the operator can easily carry out loading work because the swinging chute 6 is short.

The fluorescent lamp 4 that has entered the casing 1 is successively crushed by being sandwiched between the crushing blade 18 and the pedestal 23 by the swinging of the crushing blade 18.

The coarsely crushed glass pieces are guided by a guide 32 between a pair of rollers 24, 24,
It is finely crushed by the protrusions 25 . . . 4, 24.

The finely crushed glass pieces are transferred from the discharge port 14 to the drum can 15 through the transfer pipe 27 using air supplied by the blower 30.

The air is further sucked in by a blower 30 and recycled.

When the drum 15 is full, the cover 28 is removed, the cover 28 is attached to the empty drum 15, and the crushing process is restarted.

When processing a long fluorescent lamp, the extension chute 10 is rotated downward to form a long chute that is tilted forward and downward, as shown by the one-dot chain line and the two-dot chain line in FIG.

At this time, since the ground clearance H at the end of the extension chute 10 is very high and the loading operation is difficult, both the chute 6 and 10 are brought into a substantially horizontal state by human power. As a result, the ground height h is lowered, and the loading operation becomes easier.

After putting the fluorescent lamp 4 into the extension chute 10, when both the chute 6 and 10 are tilted forward and downward again by hand, the fluorescent lamp 4 enters the fluorescent lamp 1 under its own weight, and then the above process continues. Similarly, it can be crushed by the crushers 16 and 17.

In this way, a long fluorescent lamp can be loaded by repeatedly rocking the swinging chute 6.

(f) Effects of the Invention As described above, the present invention provides a swinging chute in the casing inlet so as to be able to swing up and down, and also allows an extension chute to be connected to the swinging chute, making it easier to load fluorescent lamps, etc. This can be easily done regardless of the length of the fluorescent lamp or the like.
