Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention is applicable to, for example, a speaker manufacturing device that glues cone paper to the peripheral surface of a speaker cone housing and the outer peripheral surface of a voice coil. It relates to a device for transporting.

[Prior art] Speaker mounting bases are formed on a turntable at equal pitches, and the turntable is driven to rotate intermittently at each speaker mounting pitch, so that multiple tasks can be performed simultaneously while the turntable is stopped. As a speaker manufacturing apparatus, there is a Japanese Utility Model Application No. 60-96914, which was previously proposed by the present applicant.

As shown in FIG. 6, the speaker mounting bases 72 are formed on the turntable 71 at a distance of 180 degrees, and the turntable 71 is rotated half a turn based on the switching operation, thereby allowing the speaker to work at the first working position. The speaker 73 is moved to the second working position, the speaker carrying tool 73 is arranged at the second working position, and the speaker 73 is moved to the second working position.
This is a semi-automatic device in which the speaker is carried out using a speaker carrying tool 74.

<<Problem to be solved>> However, in this case, the speaker carrying tool 74
Since the air cylinder 75 is used as a driving source, the turntable 71 cannot be rotated until after the air cylinder 75 completes the operation of carrying out the speaker carrying tool 74, and the cycle time of the work is long. , there is a problem of poor work efficiency.

《Means for solving the problem》 The purpose of this invention is to improve work efficiency by operating the speaker carrying device in conjunction with the rotation of the turntable. The side wall of the gear is connected with a rod to a speaker carrying tool arranged to be movable in a straight line, and the speaker carrying tool advances from the standby position to the ejection completion position in conjunction with the rotation of the turntable, and then moves backward to the standby position. The position of the joint between the drive gear and the rod when the turntable stops rotating is
The rod is characterized by being advanced by an acute angle in the direction of rotation of the drive gear beyond the position where it overlaps with the diameter of the drive gear.

《Operation》 A slider crank mechanism is formed by connecting the speaker carry-out tool arranged so that it can move in a straight line and the side surface of the turntable driving gear with a rod, and the position of the connection point between the driving gear and the rod when the turntable is stopped is fixed. is advanced by an acute angle in the rotation direction of the drive gear from the position where the rod overlaps with the diameter of the drive gear, that is, the position where the speaker carrying tool is the most retracted, so that the speaker placed on the turntable At the end of rotation when moving to the working position, the speaker carrying out tool moves to a position retreating from the standby position, so that the speaker carrying out tool does not get in the way of the moving speaker.

Further, when the speaker is set in the working position (immediately before the turntable stops), the speaker carrying tool is moved to a position slightly advanced from the most retracted position (standby position).

Therefore, when the turntable is rotated after the work by the work device is completed, the speaker carrying out tool starts carrying out the work at the same time as the rotation starts, and the working position change operation of the speaker and the work of carrying out the speaker are carried out in parallel. Become.

《Example》 Fig. 1 is a mechanical diagram of the main parts, Fig. 2 is a plan view of the elliptical speaker gluing device, Fig. 3 is a sectional view taken along line X-X in Fig. 2, and Fig. 4 is a diagram showing Fig. 2 Y- It is a Y-line longitudinal cross-sectional view.

First, the structure of a speaker to be glued with this speaker gluer 1 will be explained.

As shown in FIG. 5, this speaker 2 is an elliptical speaker in which the upper end 3a of the cone housing 3 is an ellipse with a large diameter, and the bottom 3b of the cone housing 3 is tapered at the bottom. A plate 6 is attached to which the is fixed.

A coil insertion hole 7 is formed in the center of the bottom wall 3b of the cone housing 3 and in the center of the plate 6 and magnet 5, and a post portion 8 protruding from the yoke 4 is inserted into the coil insertion hole 7. A voice coil 10 is disposed between the coil insertion hole 7 and the post portion 8, and the middle portion of the voice coil 10 is supported by a damper 9.
The lower half of is inserted.

The upper end 10a of the voice coil 10 is fixed to the center of a paper cone 11 and covered with a cap 12.

The upper peripheral edge portion 11a of the cone paper 11 is fixed to the upper peripheral edge portion 3a of the cone housing 3.

Further, a soft packing 13 is provided above the upper peripheral edge portion 11a of the cone paper 11 fixed to the upper peripheral edge portion 3a of the cone housing 3.

Then, the small diameter glued portion 1 of the upper end portion 10a of the voice coil 10 and the center portion 11b of the paper cone 11 is attached.
4 and the upper circumferential edge portion 3a of the cone housing 3 and the large diameter elliptical gluing portion 15 of the upper circumferential edge portion 11a of the cone paper 11 are glued by the gluing device 1.

This gluing device 1 has a large-diameter elliptical gluing machine 17 and a small-diameter gluing machine 1 located near the rear of a workbench 16.
8 are arranged side by side on the left and right, and both gluing machines 1 and 1 are installed side by side.
A turntable 19 is provided in front of 7 and 18.

The turntable 19 is connected to an intermittent drive means 22 consisting of a motor 20 with a speed reducer and an index 21 via a gear transmission mechanism 23, and the drive gear 24 of the gear transmission mechanism 23 and the turntable 19
The driven gear 25 formed on the outer circumference of the drive gear 25 has a ratio of 1 to 2 teeth, and is configured such that the turntable 19 rotates half a rotation when the drive gear 24 rotates once.

On the turntable 19, two speaker mounting stands 26 are arranged 180 degrees apart on the circumference around the turntable rotation center, and each speaker mounting stand 26 is rotatably supported on the turntable 19. ing. A positioning pin 27 is arranged at the center of rotation of the speaker mounting table 26 so as to be movable in and out.

A cam plate for advancing the positioning pin is provided on the lower side of the turntable 19 so as to correspond to the rotation locus of the speaker mounting table 26, and this cam plate 28 is arranged so that the turntable rotates more than the location where the large-diameter elliptical part gluing machine 17 is installed. The upper side of the direction is the starting point, and the small diameter part gluing machine 1
The movable cam plate 29 is formed in an arcuate shape with the end at the location of the cam plate 28, and a movable cam plate 29 is arranged so as to be movable in a manner continuous with the end of the cam plate 28.

A speaker carrying tool 30 is placed at the working position of the small diameter portion gluing machine 18. This speaker carrying tool 3
0 is supported by a guide 31 so that it can move in a straight line. The bracket portion 32 of the speaker carrying tool 30 and the side surface of the turntable driving gear 24 are connected by a rod 33 to form a slider crank mechanism 34, and the rotation of the driving gear 24 moves the speaker carrying tool 30 forward and backward. It is designed to let you do so.

The joint portion 35 between the rod 33 and the bracket portion 32 of the speaker carrying tool 30 is located on a straight line parallel to the axis of the speaker carrying tool guide 31 passing through the center of rotation of the drive gear 24. The articulated portion 36 with the drive gear 24 is connected to the speaker mounting base 26.
When the rod 33 is in the working position, the rod 33 is advanced by an acute angle (θ) in the rotational direction of the drive gear 24 from the position where it overlaps with the diameter of the drive gear. Therefore, the speaker carrying tool 30 is the turntable 19
The forward and backward movement will start at the same time as the rotation starts, but the speaker mounting table 26 is in the working position, that is, the standby position (W) of the speaker carrying tool 30.
Then, the connecting portion 36 between the drive gear 24 and the rod 33 advances by an acute angle (θ) in the rotational direction of the drive gear 24 from the position where the rod 33 overlaps the diameter of the drive gear 24, that is, the most retracted position (B). Because of the angular shape, at the end of rotation of the turntable 19 when the speaker mounting base 26 approaches the working position, the speaker carrying out tool 30 retreats from the standby position (W), and the speaker carrying out tool 30 This will not interfere with the carrying of the speaker 2 placed on the speaker mounting table 26 to the working position. During this evacuation period of the speaker carrying tool 30, the drive gear 24 and the rod 33
This is a period during which the drive gear 24 rotates by twice the angle (θ) advanced from the position where the rod 33 overlaps the diameter of the drive gear 24.

Further, a rotational driving force transmission mechanism 37 for rotating the speaker mounting table 26 is disposed at the small diameter portion gluing work position. This rotational driving force transmission mechanism 3
7 is composed of a support frame 39 that moves in and out by the operation of an air cylinder 38, a friction transmission wheel 40 rotatably supported on the support frame 39, and an input pulley 41 fixed to the friction transmission wheel 40. , the input pulley 41 connects the electric motor 42 to the synchronized belt 4.
It is connected by 3. An input wheel 44 is provided at the lower part of the speaker mounting base 26 , and by press-contacting the input wheel 44 and the friction transmission wheel 39 of the rotational drive force transmission mechanism 37 , the rotational force of the electric motor 42 is transferred to the speaker mounting base 26 . It has come to be transmitted to
The above-mentioned movable cam plate 29 of the support frame 38 of the rotational driving force transmission mechanism 37 is fixed, and at the same time, the rotational transmission to the speaker mounting table 26 is cut off.
Move the movable cam plate 29 in and out to remove the positioning pin 2.
7 is moved in and out of the speaker mounting table 26.

In the figure, 45 is a discharge chute, 46 is a control panel,
Reference numeral 47 denotes an attitude holding tool that maintains the attitude of the speaker 2 at the working position of the large diameter ellipse portion.

In the above embodiment, the speaker mounting stands 26 are arranged on the turntable 19 at a distance of 180 degrees, but three or more speaker mounting stands 25 may be arranged at equal pitches. In this case, the drive gear 26
The turntable 19 is made to rotate by one pitch of the speaker mounting table 26 with one rotation.

Further, the rotational driving force transmission mechanism 37 of the speaker mounting table 37 may be provided at the work position as required depending on the type of work, or may not be provided at all.

<<Effects>> In this invention, the drive gear for driving the turntable and the speaker carrying out tool are connected by a slider crank mechanism, so that the speaker carrying out tool is linked to the rotation of the turntable that transfers the speaker between working positions. Since the transfer work and unloading work are performed in parallel, the work cycle time is shortened and work efficiency can be improved compared to a system in which the turntable is rotated after the unloading work is completed.

In addition, the position of the connecting part on the drive gear side of the rod that connects the drive gear and the speaker carrying tool when the turntable is stopped is lower than the position where the diameter of the drive gear overlaps with the rod in the rotational direction of the drive gear. Since the speaker is set at a position that is acutely advanced, at the end of rotation when the speaker placed on the speaker mounting base enters the working position, the speaker carrying tool will move back from the standby position, making it difficult to move the speaker carrying tool. Even when the turntable is operated periodically, the speaker carrying tool does not interfere with the carrying of the speaker.
