Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a cullet processing device included in a manufacturing device for fluorescent lamps, light bulbs, and the like.

[Background of the invention]

FIG. 1 is a front view showing a schematic configuration of a conventional cullet processing apparatus of this type. In the figure, reference numeral 1 denotes an unnecessary glass material containing fine glass powder, ie, a cullet, which is formed when, for example, a predetermined sealing machine welds a glass tube and a mount. Reference numeral 2 denotes a sealing head 1 which constitutes the head of the sealing machine. 3 is a cullet guiding means, for example, cullet 1
4 is a chute that guides the blown cullet 1, 5 is a crusher that crushes the cullet 1-1 guided by the shoes 1 to 4, and 6 is placed inside this crusher to crush the cullet 1. This is a storage box that stores cullet 1.

By the way, in the conventional cullet processing apparatus configured as described above, the cullet 1 is simply blown away by the air nozzle 3, so there is a problem in that the fine powder of the cullet 1 is easily scattered around the sealing machine. In addition, since the cullet 1 is guided from the chute 4 to the crusher 5 by using its own weight, it is constrained by the length and inclination angle of the chute 4, and therefore the crusher 5
Due to restrictions on the size and location of the crusher 5, the crusher 5 is placed close to the sealing machine 1, resulting in a problem that the surroundings of the sealing machine become cluttered. Furthermore, the size of the crusher 5 is constrained, which in turn is constrained by the size of the storage box 6, and therefore the storage box 6 is likely to be transported many times. Incidentally, related devices of this type include, for example, Japanese Utility Model Publication No. 59-7719.

[Purpose of the invention]

The present invention was made in view of the above-mentioned problems in the prior art, and its purpose is to minimize the amount of cullet powder scattered, as well as to eliminate restrictions on the size and location of the crusher, and to reduce the amount of cullet powder. It is an object of the present invention to provide a cullet processing device that can eliminate restrictions on storage boxes for storing powder.

[Summary of the invention]

(°°"ty: MAt"r: #K *躬′"""
'I A conveying pipe connected to the suction side and conveying the cullet;
The structure includes a separation tower that is provided in the middle of the transport pipe and has a space having a cross-sectional area larger than the opening area of the transport pipe, and a cullet guiding means that guides the cullet to the open end of the transport pipe. .

[Embodiments of the invention]

Hereinafter, the cullet processing apparatus of the present invention will be explained based on the drawings.

FIG. 2 is a front view showing a schematic configuration of an embodiment of the present invention. In this figure, the same members as those shown in FIG. 1 described above are designated by the same reference numerals. In Figure 2,
A dust collector 7 includes a filter 8 and a storage box 9 disposed below the filter 8. 10 is a conveying pipe connected to the suction side of the dust collector 7, and its open end 11
is arranged near the cullet 1 on the sealing head 2 constituting the sealing machine. Reference numeral 12 denotes a separation tower provided midway through the transport pipe 10, and the separation tower 12 has a closed space having a cross-sectional area larger than the opening area of the transport pipe 10.

13 is a push plate that can come into contact with the cullet 1 on the sealing head 2; 14 is an air cylinder that moves this push plate 13;
These pushing plates 13 and the air cylinder 14 constitute means for guiding the cullet 1 on the sealing head 2 to the curdle 1 which guides it to the open end 11 of the conveying pipe 10.

15 is a crusher disposed below the separation column 12, 16
is a storage located below this crusher 15; ]7.
17' is a shutter that opens and closes a passage connecting the separation column J2 and the crusher 15, and 18 and 18' are air cylinders that operate these shutters I7 and 17', respectively.

The operation of the cullet processing apparatus configured as described above is as follows. When the dust collector 7 is driven, the conveyor pipe 1
A negative pressure is created within the zero. In this state, when the air cylinder 14 is operated and the push plate 13 guides the cullet 1 to the open end 11 of the transport pipe 10, the cullet 1 is transferred to the transport pipe 10.
The air flows as shown by arrows 19 and 20 along with the air current within 0. Then, in the separation tower 12 having a space with a cross-sectional area larger than the opening area of the transport pipe] 0, the velocity of the air flow is reduced, so the cullet 1 falls under its own weight in the distribution tower 12, and is separated. It is deposited at the bottom of column 12. At this point, the air cylinders 18, 18' are activated and the shutters 17.
When 17' is opened appropriately, the cullet 1 in the separation column J2 falls into the crusher I5 and is crushed by this crusher I5. The crushed cullet 1 is further stored]
6, and is deposited as cullet powder 2]. On the other hand, the so-called fine powder in the cullet 1 flowing through the transport pipe 10 that did not fall into the separation tower 12 further flows inside the transport pipe 10 as shown by arrows 22 and 23. The flow is sent to the filter 8 section of the dust collector 7 as shown by the arrow 24, where it is captured and stored in the storage box 9 of the dust collector 7.
The cullet powder 25 is deposited on the ground.

In this simple cullet processing equipment,
Since negative pressure is generated in the conveying pipe 10 by driving the dust collector 7, the cullet powder generated during mount welding is well sucked into the conveying pipe IO, thus minimizing the amount of cullet powder scattered around the sealing machine. can be suppressed to Moreover, since the conveying pipe 10 can be set to be long as necessary, and the separation column 12 can be placed sufficiently high, there are no restrictions on the size and placement position of the crusher 15. Further, for the same reason, there are no restrictions on the size of the storage 16, so the storage 16 can be made large in size.

In the above embodiment, the air cylinder 14 and the push plate 13 are used as the cullet guide means for guiding the cullet 1 to the open end 1 of the conveying pipe 10, but instead of the air cylinder 14 and the push plate 13, An air nozzle 3 as shown in FIG. 1 can also be provided. When configured in this way, it is inevitable that some cullet powder will be scattered around the sealing machine, but since negative pressure will be generated in the conveying pipe 10, the conventional processing apparatus shown in FIG. The amount of scattering can be halved compared to

Further, in the above embodiment, the cullet powder from the separation tower 12 is deposited in the storage mold 16 via the air cylinder 18, 18', the shutter 17, 17', and the crusher 15, but such a pulsator is not necessarily used. 15. Air cylinder] 8.18', shutter 17.17', storage type 16 is not required; for example, shutter 17.1.7
・Ya□□5, □, 1. . Vehicles such as I-racks may be arranged in the following manner.

〔Effect of the invention〕

Since the karen 1-processing device according to the present invention is configured as described above, it is possible to minimize the amount of scattering of karen 1-powder, and also to reduce the restrictions on the size and placement of the crusher and the cullet powder. Restrictions on storage boxes can be removed, resulting in the following effects.

■ The human body can be protected from cullet powder, and the floor surface near where cullet powder is generated can be kept clean.

(2) Karen 1 - Since there is no need to arrange a crusher near the cullet powder generation location, a wide space can be set up around the cullet powder generation location.

■ The storage box, tray, etc. placed below the separation tower can be set to a large size, and only a very small amount of fine powder accumulates in the storage box of the dust collector, so cullet powder is The number of transportation times can be reduced.
