Abstract

PURPOSE:To reduce influences of noise upon an operator by separately disposing a sorting enclosure and a blower enclosure for enclosing a vacuum blower producing a great noise. CONSTITUTION:A plurality of sorting enclosures 2 are separately disposed in an operation chamber 1, and a blower enclosure 6 enclosing a vacuum blower 5 and the like is mounted in a blower chamber 4 separated from the operation chamber 1 by a partition wall 3, the blower enclosure 6 and the sorting enclosures 2 being coupled to one another by a duct 7. Thus, air pressure for transporting and sorting documents, paper money or the like in the sorting enclosure 2 is conducted through the duct 7 into the sorting enclosure 2 by the vacuum blower 5 in the blower enclosure 6. The sorter is required to have enclosure panels 8 of the sorting enclosure 2 which are comparatively light and easily opened and closed in view of maintenance.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sorting machine, such as an OCR sorting machine or a bank note inspection machine, which uses air pressure to transport and classify documents, banknotes, etc.

The above sorting machines are often installed in multiple units in one room, and each one is independent.The housing that makes up each sorting machine contains a container for transporting and sorting documents, banknotes, etc. Vacuum floors, etc. are stored inside. These vacuum prowers and the like have been problematic due to their large noise and psychological impact on the operator.

The present invention has been made with this in mind, and the classification housing and the noisy vacuum blower are housed separately from the nine blower housings, and the floor housing is effectively sound-insulated. The influence of the child on the operator! The purpose of the present invention is to provide a classifier with a reduced number of characters.

The present invention will be explained below with reference to the drawings.

FIG. 1 is an external perspective view showing an embodiment of the present invention.

In the figure, a plurality of classification casings 2 are installed separately and independently in an operation room 1. Separation 113 from the above operation room l
In the dangerous prower chamber 4, which is divided by
and the classification housing 2 are connected by a duct 7.

Therefore, the air pressure for conveying and sorting documents, banknotes, etc. in the sorting case 2 is guided into the sorting case 2 through the duct 7 by the vacuum purer 6 in the proer case 6. Sorting machines often cause paper jams, etc.
From the viewpoint of maintainability, etc., the housing panel 8 of the classification housing 2 is required to be relatively light and capable of being easily opened and closed. However, when the weight of the housing panel 8 is reduced, the surface density decreases and the sound insulation performance decreases.

Therefore, in the present invention, as in the above-mentioned configuration, the proar housing 6 housing the vacuum proar 5, which is a raw source of noise, is installed in the proa chamber 4 separated by the partition wall 3. In other words, this floor casing 6 only houses the vacuum prower 5, which requires relatively little maintenance and inspection, so the housing panel 9 for opening and closing the prower housing 6 may be made heavy, which improves the sound insulation performance. This allows for improvements to be made.

FIG. 2 shows a cross-sectional view of the proa case 6. As shown in FIG.

The outer periphery of the proa housing 6 is constructed of a housing panel 9 made of a relatively heavy material made of a thick metal such as iron.

A sound absorbing material 10 such as polyurethane or glass wool is pasted on the inner surface of the housing panel 9.

A vacuum prower 5 is fixed to the bottom surface 9a of the housing panel 9 via a vibration isolating rubber 11, and the vacuum prower 5 is connected to an absorption side duct (13) that opens below the bottom surface 9a via a flexible pipe 12. is connected to. This suction side duct 13
On the upstream side of the suction port 14 of the compartment 15, a number of extinguishers 16 are vertically arranged alternately in the horizontal direction along the side wall of the compartment 15.

1 light, the discharge side duct 17 leading out from the proa housing 6 is
Similarly, it is connected via a flexible pipe 18 so that vibrations are not propagated to the proar housing 6.

The proa housing 6 configured as described above has an improved sound insulation effect due to the heavy housing panel 9 and the sound absorbing material 1° attached to its inner surface. and the suction side duct 13
and the discharge side duct H7 are also respectively fixed via flexible pipes 12 and 18 so as not to propagate vibrations, and their synergistic effect can effectively reduce noise.

FIG. 3 is a side view showing another embodiment of the present invention. In this embodiment, a proer chamber 19 is provided under the floor i of operation-1, and a vacuum proer 5 is installed in this proer chamber 19. This vacuum blower 5 and each classification housing 2 provided on the floor in the operation room 1 are connected by a duct 7.

According to this embodiment, the floor surface serves as a sound insulating wall, and the under-floor proa chamber 19 has the same effect as the proa case 6 in the previous embodiment, reducing noise to the operator of the sorting machine. The total impact can be reduced. Even if the weight of the floor surface 2o is increased, the area density is increased, and the sound insulation performance is improved, the classification housing 2 and the vacuum blower 5, which is the main noise source, are installed separately, and the classification housing itself Since it can be manufactured using normal materials and structures, it does not affect maintainability in any way.

As described above, according to the present invention, the classification housing, which is the operation part, and the vacuum blower, which is the main noise generation source that supplies a predetermined air pressure, are installed in isolation, and the vacuum blower is housed in the vacuum blower. Since the sound insulation performance of the housing or the proa chamber has been improved, the psychological impact on the operator of the sorting machine can be reduced.

Claims (1)

[Claims] In a sorting machine that transports and sorts documents, banknotes, etc. using pneumatic pressure, the classification casing that serves as the operating unit and the soundproofed prower housing that houses the vacuum prower that supplies a predetermined air pressure are installed separately from each other. A sorting machine is characterized in that these are connected by a duct.
