DESCRIPTION JPS6046197
[0001]
FIELD OF THE INVENTION The present invention relates to an apparatus for feeding cone paper
to a cone paper loading stage of a speaker manufacturing line. <Conventional technology and its
problems> Conventionally, corn paper is handled as a convenience for transportation, storage,
etc.-1-A large number of sheets are piled up and handled and divided into pieces at the stage of
supplying to the cone paper loading stage of the speaker production line It is However, so far, it
has not succeeded in taking out corn paper exactly one by one from among a large number of
machines stacked. For example, even if it is attempted to take out only one top cone paper with a
vacuum chuck, it is not uncommon for the next two to three cone paper to be taken out together.
As described above, since the number of sheets to be taken out is not exactly one, conventionally,
it has been a problem that the supply of corn paper to the corn paper loading stage has to be
relied upon manually. <Object of the present invention> In view of the above-mentioned
circumstances, the present invention is a cone paper feeding apparatus for a speaker
manufacturing line, which can accurately take out cone paper one by one from a large number of
stacked sheets and feed it to a cone paper loading stage. Intended to be provided. <Configuration
and Effect of the Present Invention> In order to achieve the above object, according to the
present invention, the vacuum chuck is reciprocably displaced between the upper side of a large
number of stacked cone sheets and the upper side of a cone sheet loading stage. And a lift drive
unit vertically supported by the base frame to drive the vacuum chuck horizontally, and a lift
drive unit moving the vacuum chuck up and down. The vacuum chuck is movably supported by
the base and the base It is characterized in that at least two shields and a pick-up drive device for
driving the tips of the shields in a direction to approach each other are provided, and a suction
port is opened at the tips of the shields. According to the present invention configured as
described above, only the topmost cone paper is reliably picked up and adsorbed by the shield
and transferred to the cone paper loading stage, so that a large number of cone paper sheets are

stacked. It takes out exactly one sheet at a time, and it is possible to obtain the effect of finishing
feeding on the corn paper loading stage. In addition, as a result, the operation of feeding corn
paper to the corn paper loading stage can be mechanized, work efficiency can be improved, and
labor cost can be saved. <Description of Embodiments> Next, embodiments of the present
invention will be described based on the drawings. FIG. 1 is a front view of an embodiment of the
present invention, and FIG. 2 is an enlarged longitudinal front view of the main part thereof. The
cone paper feeding apparatus 1 includes a base frame 4 provided from the upper side of the
cone paper mounting stay 2) 2 to the upper side of the cone paper stocker 3 on the side of the
stage 2.
The carriage 6 is horizontally movably supported by the base frame 4 via the upper and lower
traverse guide rods 5. The carriage 6 is reciprocally driven by a traverse drive unit 7 comprising
an air cylinder supported by the base frame 4. A vacuum chuck 9 is supported on the carriage 6
via a lift guide rod 8 so as to be movable up and down. The vacuum chuck 9 is driven to move up
and down by a lift drive unit 10 comprising an air cylinder 8 supported by a carriage 6. As
shown in FIG. 2, the vacuum chuck 9 includes a base 91 connected to the lower end of the
elevation guide rod 8 and two shields 92 swingably supported on the lower surface of the base
91. To this base 91 is attached a pick removal drive 93 composed of an air reel 3-ring. The pickup drive device 93 is extended to push down the cam 94 continuously connected in a bell crank
shape to the base end of the shield part 92 to make the tips of the both collar parts 92 approach
each other. Between the two collars 92, a return spring 95 is inserted which tries to push and
spread the tip of the collars 92 against the picking device 93. At the tip of each shield 92, a
suction port 96 is opened. An air passage (not shown) is formed inside each shield 92 and cam
94, and one end of the air passage is communicated with the suction port 96. The other end of
the air passage is connected to a joint 97 provided at the tip of the cam 94. A vacuum source (not
shown) of the vacuum chuck 9 is connected to the joint 97. A cone paper support shaft 31 is
erected on the cone paper stocker 3, and a cone paper support 32 is externally fitted to the cone
paper support shaft 31. The cone paper receiving table 32 is driven to move up and down by an
elevation drive (not shown). A large number of sheets of cone paper 33 are stacked and placed
on a cone paper stand 32, and the cone paper stand 32 is displaced by the lift drive device so
that the uppermost cone paper 34-3 is always positioned at a predetermined height. Be
configured to The cone paper stocker 3 is provided with a coil spring 34 in order to expose the
cone paper 33. Next, the operation of the above-described cone paper feeding device 1 will be
described. First, the carriage 6 and the vacuum chuck 9 are displaced by the traverse drive unit 7
to the two sides of the cone paper 33 placed on the cone paper stocker 3. Then, by operating the
lifting and lowering drive device 10, the cone paper 33 is slightly pressed by the vacuum chuck
9. As a result, the topmost cone paper 33 is placed in a substantially horizontal position. Next,
the tips of the both eyebrows 92 are made to approach each other by extending the pick-up drive
93. In FIG. 2, the swing range of both collar portions 92 is shown exaggeratingly by a solid line
diagram and a one-dot chain line diagram, but the swing angle of both collar portions 92 is

actually set to about 2 to 10 degrees Be done.
Due to the swinging of the both ridges 92, the uppermost cone paper 33 is picked up by the tips
of both ridges 92, and the sticking of the paper with the cone paper 33 is eliminated.
Furthermore, by connecting a vacuum source to the suction port 96, the uppermost cone paper
33 is adsorbed to the suction port 96. Then, when the vacuum chuck 9 is raised, only the
topmost cone paper 33 absorbed is lifted. The cone paper 33 of the next and subsequent stages
is divided into the most two-staged cone paper 33 and the mackerel at the time of the picking
operation of the uppermost-stage corn paper 33 by the two ridge portions 92). It can not be
lifted by sticking to paper 33. In addition, the coil spring 34 of the cone paper stocker 3 has an
effect of separating the cone paper 33 prior to picking the cone paper 33 and picking up the
uppermost cone paper, and facilitating the sheet of paper # 33 #f being taken out one by one.
doing. The uppermost cone paper 33 picked up and absorbed by the vacuum chuck 9 displaces
the carriage 6 to the upper side of the cone paper apparatus stage 2 by the traverse drive unit 7
and the vacuum chuck 9 is predetermined by the lift drive unit 10 By lowering the connection
between the vacuum source and the vacuum chuck 9 halfway to complete suction, the speaker
assembly S on the stage 2 is mounted. The pick-up driving device 93 may be shortened at any
time after adsorption of the corn paper 33 to the suction port 9G is completed. In the abovedescribed embodiment, the vacuum chuck 9 is configured to move in a gate-like trajectory of up,
down, down, but it is necessary to adjust the operation timing of the traverse drive unit 7 and the
elevation drive unit 10 It may be configured to be moved by drawing a mountain-shaped locus
such as oblique rise and oblique fall. Furthermore, the traverse driving device 7 and the lifting
and lowering driving device 10 are configured to be shared by a single rocking driving device,
and the vacuum chuck 9 is supported by supporting the vacuum chuck 9 via the rocking arm by
this driving device. It is also within the scope of the present invention to be configured to draw
and move an arc-like trajectory.
