Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a button supply device for a button-attached sewing machine, in which buttons sent from a button supply source are sequentially supplied one by one through a horizontal transport path.

[0002]

2. Description of the Related Art The present applicant has previously proposed and implemented a button supply device as shown in FIGS. This button supply device is completely different from the conventional concept of the button supply device in which the button is slid and dropped obliquely downward by its own weight to convey the button, and the button sent from the button supply source is moved along the horizontal conveyance path. This is forcibly transported.

An outline of this prior art will be described below with reference to the drawings. The buttons B sent from the outlet 13c of the button supply unit 13 are first fitted into the notches 14a formed in the first rotary plate 14 one by one, and the lower surface thereof is supported by the first support plate 16. It And those buttons B
Is the first horizontal arcuate path O1 caused by the first rotating plate 14 which is intermittently rotated by the AC motor 15 every 90 degrees.
(See FIG. 8A) The first support plate 1 is conveyed at a time when it is rotated by 180 degrees from the delivery port 13c.
It reaches the discharge port (first delivery position) 16a1 formed in 6 and falls downward from here, and is fitted into the button insertion hole 21a of the second rotary plate 21 and supported by the second support body 23. It

After this, the button B is connected to the first rotary plate 14 through a gear or the like, and the second rotary plate 21 is engaged.
Intermittently rotate every 45 degrees to reach the second delivery position, that is, the discharge port 23a (see FIG. 7) formed in the second support member 23, and a pair of opening / closing provided immediately below the discharge port 23a. It falls on the plates 43 and 44 (see FIG. 9). At this time, a centripetal mechanism described later operates to align the center of the button B with the center ha of the opening h of the opening / closing plates 43 and 44. As a result, the center of the button B is located at
It also coincides with the center P1 of the button holding portion 28a provided on the button holding arm 28 standing by below. next,
By the operation of the cylinder 32 and the motor 35, the button rotating member 29 located above the second discharge port 23a rotates and descends, and together with the button B, the opening / closing plates 43, 44.
Rotate while pressing down. As a result, the opening / closing plate 4
The tip end of a locking pin 28a1 (see FIG. 8B) projecting from the button holding portion 28a of the button supply arm 28 projects from the opening h formed in 3, 44 and into the threading hole Ba. Is inserted. Here, the opening / closing plates 43 and 44 are opened to release the button B, and the button B is held by the button holding arm 28. After this, button B is the motor 26
By the rotation of the button supply arm 28 by the above, it is fitted and held between the button holding portions 12b, 12b of the button sewing machine 12.

By the way, as described above, the second outlet 23
The center of the button B sent from the a to the open / close plates 43 and 44 is the center ha of the opening h of the open / close plates 43 and 44, that is, the button holding portion 28a of the button supply arm 28.
As the centripetal mechanism that matches the center P1 of the, those shown in FIGS. 10 and 11 were used. In the figure,
Reference numeral 70 indicates this centripetal mechanism, and 71, 72, 73 indicate three positioning levers (positioning members) of this centripetal mechanism.
Indicates. These three positioning levers have the same shape,
Each is rotatably attached to the lower surface of the second support body 23 by fulcrum shafts (rotational fulcrums) 71c, 72c, 73c. Then, each positioning lever has a positioning portion 71A, 72A, 73 having an arcuately curved inner surface.
A is formed.

Further, the fulcrum shafts 71a, 72a, 73a
Are arranged at equal intervals on the circumference centered on the center ha of the openings h of the opening / closing plates 43 and 44. 74, 75,
Reference numeral 76 is a connecting link for connecting the respective positioning levers 71, 72, 73, and these connecting links are the connecting shaft 71.
Both ends of the positioning levers 71, 72, 73 are rotatably connected by a, 71b, 72a, 72b, 73a, 73b. Then, three 4-node link mechanisms are formed by the adjacent positioning levers and the connecting links that connect them, and the connecting points of each 4-node link mechanism, that is, the fulcrum shaft and the connecting shaft are parallelogram-shaped. It is located at the top. 77 is the positioning lever 71
Is a working link whose one end is connected by a connecting shaft 71d, and a roller 77a is projectingly provided at the other end, and the roller 77a moves to an arc-shaped long groove 80a formed in the cam plate 80. Fitting is possible. This cam plate 80
Is rotatably supported horizontally by a support shaft 81, and a long hole 79a is formed at the other end of the operating plate 79 inserted into the support shaft 81. The long hole 79a is formed in the long hole 79a. A pin 78a1 protruding from one end of an operating rod 78a of the solenoid 78 is rotatably inserted.

When the solenoid 78 is actuated and the actuating rod 78a in the projecting state is actuated and the actuating rod 78a in the projecting state is attracted to the position shown in FIG. 11, the actuating plate 79 and the cam plate 80 are 11 is pulled by the operation lot 78a and rotates about the fulcrum shaft 81 in the arrow M direction in FIG. 11, and the operation link 77 moves in the arrow L direction via the roller 77a fitted to the cam plate 80. This working link 7
The movement of 7 causes the positioning lever 71 to rotate counterclockwise from the initial position shown in FIG. 10 about the fulcrum shaft 71c.

By the movement of the operation link 77, the positioning lever 71 rotates counterclockwise in FIG. 8 around the fulcrum shaft 71c, and the rotation is transmitted to the positioning levers 72 and 73 through the connecting links 74 and 75. Then, these levers also rotate counterclockwise from the initial position shown in FIG. 10 about the fulcrum shafts 72c and 73c. As a result, the opening / closing plates 43, 44
Button B that has fallen up has positioning levers 71, 72, 7
The three positioning portions 71A, 72A, 73A move to the center position P1 and are finally held by the positioning portions 71A, 72A, 73A from three sides (see FIG. 11). At this time, each positioning lever 71, 7
Since 2 and 73 form a parallelogram four-node link mechanism together with the connecting links 74, 75 and 76, all of them rotate at the same angle. As a result, FIG.
In the positioning state as shown in FIG.
A, 72A, and 73A come into contact with the outer peripheral surface of the button B at equal intervals, and the center of the button B can be accurately aligned with the central portion P1. In this way, when the positioning levers 71, 72, 73 move to the positioning position of the button B, the rotational position detection sensor S detects the detection plate 82.
Is detected, an ON signal is output, and the CPU
A control circuit such as the above controls the drive circuit of the solenoid 78 to bring the solenoid operating rod 78a into a protruding state, and the operating link 77 is moved in the K direction to return to the initial position shown in FIG.

[0009]

As described above, according to the above-mentioned prior art, the first and second rotary plates 14 and 21
Since the button B is forcibly transported along the horizontal arcuate path, compared to the conventional device that slides and drops the button by its own weight, clogging of the button in the transport path can be eliminated and stability is achieved. Although it is evaluated that the above performance can be obtained, under the present circumstances where the tendency of high-mix low-volume production is increasing, the following problems have been desired to be solved. That is, in the above-mentioned prior art, the button insert holes 21a having the same diameter are all formed in the second rotary plate 21, and the diameter is formed assuming the maximum diameter of the button to be applied. Further, in the centripetal mechanism, since each positioning member must always be positioned outside the button that drops from the button insertion hole, its initial position is slightly larger than the maximum button diameter according to the setting of the button insertion hole. It was set on the circumference. Therefore, when the button B has a small diameter, the positioning members 71, 72, 73 and the opening / closing plates 43, 4 in the initial position are arranged.
Therefore, a large gap is created between the button B and the button B that has dropped onto the position 4, and a large inertial force is generated in each positioning member during the movement of the gap, and a large impact is generated when the button B is brought into contact with the positioning member. Due to this impact, the button B may pop up or stand up, and in some cases, may be damaged. However, if the second rotary plate 21 is replaced and the initial position of the centering mechanism is changed according to the diameter of the button to be transported, it is possible to always properly transport the button. With this, when the button diameter is frequently changed due to high-mix low-volume production or the like, the burden on the operator is extremely heavy, and the productivity is lowered.

The present invention has been made by paying attention to the above-mentioned problems, and even when the button diameter to be frequently carried is changed due to the production of a wide variety of products in small quantities, etc., without changing the parts,
An object of the present invention is to provide a button supply device that can easily realize an appropriate transport operation.

[0011]

SUMMARY OF THE INVENTION According to the present invention, after buttons which are sequentially delivered from a button supply source are conveyed onto the opening / closing plate along a horizontal arcuate path by the first and second rotating plates, the buttons are placed on the opening / closing plate. In the button transfer device, which is positioned by the centripetal mechanism so that the center of the button and the predetermined set point set on the opening / closing plate match, and the position of the button is transferred to the predetermined supply position by the button supply arm,
A plurality of types of button insertion holes of different diameters are formed at equal intervals on the second rotating disk, and button insertion holes corresponding to the button diameter indicated by the input means are formed at the second delivery position. The disk drive control means for controlling the second drive means so as to be stopped and the positioning member drive means are controlled corresponding to the button diameter also instructed by the input means to move the initial position of the positioning member to the inside and outside. And a positioning member drive control means to be changed.

[0012]

In the present invention having the above structure, when the operator indicates the button diameter to be conveyed by the input means,
The disk drive control means controls the second drive means in response to the instruction, and the initial position of the second rotary plate is adjusted so that the button insertion hole suitable for the instructed button diameter stops at the second delivery position. To set. At the same time, the positioning member drive control means controls the positioning member drive means to set the initial setting position of each positioning member in the centripetal mechanism to a position close to the instructed button diameter. As a result, the button conveyed by the second rotary plate surely falls inward of each positioning member, and each positioning member moves from a position relatively close to the button conveyed on the opening / closing plate. Since the movement is started, the impact caused by the contact between the positioning member and the button becomes extremely small, and the damage or rising of the button is prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
It will be explained based on. The same or corresponding parts as those in the above embodiment are designated by the same reference numerals, and the detailed description thereof will be omitted. The button supply device in this embodiment is provided with a disc-shaped second rotary plate 2 as shown in FIG. 1 in place of the second rotary plate 21 in the above-mentioned conventional technique. The second rotary plate 2 is located on the second button support plate, and the center of the second rotary plate 2 is rotatably supported by the support shaft 3. The second rotary plate 2 and the first rotary plate 14 are rotated by independent driving means. That is, the first rotary plate 14 is rotated by the first motor (first driving means) 15, and the second rotary plate 2 is rotated by the second motor 3 (second driving means). ) To rotate. A drive gear 4 is fixed to the rotation shaft 3a of the second motor 3, and the drive gear 4 meshes with a gear portion 2g formed on the peripheral surface of the second rotary plate 2. is doing. Therefore, when the drive gear 4 is rotated clockwise or counterclockwise by the first motor 3, the second rotary plate 2 is rotated counterclockwise or clockwise. Furthermore, the second rotary plate 2 has two types of button insertion holes 2 of large and small sizes.
a and 2b are formed, and each of the button insertion holes is formed two by 180 degrees. Hereinafter, 2a is referred to as a large hole and 2b is referred to as a small hole.

On the other hand, FIG. 2 is a diagram showing the centripetal mechanism 7 in this embodiment. This centripetal mechanism 7 has three positioning members 71, 72, 73 and, like the prior art,
Connection links 74, 75 for connecting these positioning members,
76, each positioning member is moved by moving the operating link 77 in the arrow A direction or the B direction.
It moves inward and outward at the same time with respect to the set point ha set in the opening h of 44, which is similar to the above-mentioned prior art. However, in this embodiment, a positioning member drive mechanism as described below is provided in the operation link 77 for operating each of the positioning members 71, 72, 73, and this mechanism is different from the prior art. In the figure, reference numeral 8 is a rotary link whose middle portion is rotatably supported by a fulcrum shaft 8a, and is always urged by a spring 9 in the clockwise direction in the figure. Further, a roller 77a axially attached to one end of the operation link 77 is fitted and inserted into an elongated hole 8b formed between one end of the rotation link 8 and the fulcrum shaft 8a. The operation link 77 is adapted to move in the direction of arrow A or B in conjunction with the rotation of 8. Reference numeral 10 is a drive solenoid that connects the plunger 10a to one end of the rotary link 8. The drive solenoid 10 is turned on and off by the control means described later. In the on state, the plunger 10a projects to rotate the rotary link 8 against the spring 9 in the counterclockwise direction in the figure. It has become. Reference numeral 11 is a locking solenoid which is turned on and off by a control means which will be described later.
1a protrudes in the ON state and immerses in the OFF state. Also, this plunger 11a
One end of the rotary link is opposed to one end of the rotary link,
Normally, the biasing force of the spring 9 makes pressure contact with one end of the rotary link 8.

FIG. 3 is a diagram showing the configuration of the control system circuit according to this embodiment. In the figure, 100 is a CPU 10 as a positioning member drive control means and a disk drive control means.
1 is a well-known microcomputer including a ROM 102 and a RAM 103, and on the output side of the CPU 101, in addition to the sewing machine motor M and the button supply unit 13,
The first and second motors 15 and 3, the drive solenoid 10, the locking solenoid 11, the rotary member lifting cylinder 32, the rotary member rotary motor 35, etc. are connected. Also, 104
Is an input device for inputting various commands and data such as the diameter of a button to be conveyed.

Next, the operation will be described based on the above configuration. At the start of the button supply operation, the operator determines whether the button B stored in the button supply unit 13 to be conveyed is a large button or a small button.
Instruct by. In response to this instruction, the CPU 101 selects the large hole 2a or the small hole 2b as the button insertion hole to be used, and the discharge port 23 which is the second transfer position.
It is determined whether the button insertion hole (initial button insertion hole) stopped at a is the large hole 2a or the small hole 2b, and this initial button insertion hole does not match the button insertion hole to be used. In this case, the second motor 3 is controlled to rotate the second rotary plate 2 by 90 degrees, and if they coincide with each other, the second motor 3 is not driven and the position of the second rotary plate 2 is adjusted. Is maintained as is. As a result, the button insertion hole to be used is set in the discharge port 23a. For example, when the designated button is a large button and the initial button insertion hole is the small hole 2b, the second rotary plate 2 is rotated by 90 degrees to make the second rotary plate 2 large. The hole 2a is located at the discharge port 23a.

By instructing the size of the button, the CPU 101 controls the locking solenoid 11 of the centripetal mechanism 70 in the following manner in addition to the control of the second motor 3 as described above. That is, when the instructed button is a large button, the locking solenoid 11 is turned off, and when it is a small button, the solenoid 11 is turned on. When inputting the size of this button, the drive solenoid 10 that performs centripetal operation is in the OFF state. Here, when the locking solenoid 11 is turned off in accordance with the instruction from the input device 104, the rotation link 8 causes the plunger 1 of the locking solenoid 11 to move by the urging force of the spring 9.
1a is retained at the retracted position I1, and the operating link 77 is retained at the leftmost position. The positioning members 71, 72, 73 are held at positions most distant from the set point h1 in conjunction with the operation link 77, and the inner circles of the positioning portions 71A, 72A, 73A have the maximum diameter T1. Take In addition, this maximum diameter T1 is the large hole 2 of the second rotary plate 2.
It is set to be the same as or slightly larger than a.

When the locking solenoid 11 is turned on, the plunger 11a projects leftward and holds the rotary link 8 at the intermediate position I2 against the biasing force of the spring 9. As a result, the operating link 77 is held at the intermediate position on the right side of the leftmost position, and the positioning members 71, 72, 7
3 is held at a position where the inner circle of the positioning portions 71A, 72A, 73A has a diameter (intermediate diameter) T2 smaller than the maximum diameter L1. The intermediate diameter T2 is set to be equal to or slightly larger than the small hole 2b of the second rotary plate 2.

After the initial button insertion hole and the initial positions of the positioning members 71, 72, 73 have been set in this way, when the button supply operation is instructed by the input device, the first and second motors 15 are driven. , 3 are driven, the first and second rotary plates 14 and 2 are intermittently rotated by 180 degrees in synchronization with each other, and the buttons sent from the button supply unit 13 are sequentially arranged along the horizontal arcuate paths O1 and O2. Carry on. Then, the button B that has reached the discharge port 23a, which is the second transfer position, is dropped and held on the opening / closing plates 43 and 44 as in the conventional case. At this time, the button B falls into the range of the button insertion hole 2a or 2b, but the button insertion hole 2a or 2b has a diameter slightly larger than the outer diameter of the button. The position of the button B falling within the range is hardly displaced, and the center of the button B is not largely displaced from the set point ha. Therefore, button B
Is reliably dropped inside the positioning members 71, 72, 73 waiting on the circumference slightly larger than the button insertion hole.

After that, the CPU 101 controls the drive solenoid 1
When 0 is turned on, the plunger 10a is in a protruding state. As a result, the rotation link 77 rotates counterclockwise around the fulcrum shaft 8a against the spring 9, and one end of the rotation link 77 is separated from the plunger 11a of the locking solenoid 11 in the projecting state. By this rotation of the rotation link 8, the operation link 77 is moved leftward from the intermediate position I2, and each positioning member 7 is moved.
1, 72, 73 move toward the set point, regulate the position of the button from three directions, and match the center of the button with the set point. In this positioning operation, each positioning member 71, 7
Since the gap formed between the buttons 2, 73 and the button B is extremely small, the inertial force of the positioning members 71, 72, 73 generated during the movement of the gap is also extremely small, and the button B has There is almost no shock.
Therefore, in the centripetal operation, the inconvenience such as the rising, popping-out, or damage of the button B does not occur, and the button B is reliably positioned at the proper position. The positioned button B is then supplied to the button holding parts 12b, 12b of the sewing machine by the button supply arm 28 in the same manner as in the prior art.

By the way, in the above-mentioned embodiment, the second rotary plate 2 is provided with the button insertion holes 2a and 2b of two kinds, large and small.
Although it is formed through an interval of 80 degrees and the initial position of each positioning member of the centripetal mechanism can be set in two stages,
It is possible to form three or more types of button insertion holes in the second rotary plate, and even in the centering mechanism, it is possible to set the initial position of each positioning member in three or more stages. is there. For example, it is possible to use the second rotary plates 2X and 2Y as shown in FIGS. 4 and 5. The second rotary plate 2X shown in FIG. 4 has button insertion holes 2X1, 2X2, and 2X3 having three kinds of diameters of large, medium, and small formed at various intervals of 180 degrees, and has three buttons. It is formed corresponding to the diameter of the type. In addition, the second shown in FIG.
The rotating plate 2Y has button insertion holes 2Y1, 2Y2, 2Y3, 2Y4 having four kinds of diameters of extra large, large, medium and small, arranged at every 180 degrees.

As described above, a button insertion hole having a desired diameter can be formed in the second rotary plate according to the type of button diameter to be applied. Further, the intervals between the positions where the various button insertion holes are formed are not limited to the intervals of 180 degrees as described above, and the intervals may be formed at other intervals. For example, like the second rotary plate 2Z shown in FIG.
Button insertion hole 2Z1, which has three types of diameters, large, medium and small
It is also possible to form 2Z2 and 2Z3 every 90 degrees. Of course, in this case, the second
It is necessary to set the intermittent rotation angle of the rotating plate of No. 9 to 90 degrees, or set it to 1 / n (n is an integer). Further, when the number of button insertion holes of the second rotary plate 2 is set to three or more as described above, the initial position of each positioning member in each centripetal mechanism is the same as the number of button insertion holes or , May be set in a plurality of steps below that. In addition,
When the initial position of each positioning member is set in three or more steps, the locking solenoid 7 may be replaced by a locking member that advances and retracts stepwise by a stepping motor or the like.

Further, when three or more kinds of button insertion holes are provided, it is necessary to control the second motor 3 slightly different from the above embodiment. For example, the second rotary plate 2X as shown in FIG.
In the case where the initial positions of 1, 72, 73 can be changed in two steps, for example, the following control is performed.
Here, the operator does not instruct the type of the button B to be transported, but directly inputs the button diameter by the input device 104. In response to this input, the CPU 101 first selects a button insertion hole (button insertion hole to be used) suitable for the input button diameter, and further, the button insertion hole currently stopped at the second delivery position 23a. It is determined whether the (initial button insertion hole) is the large hole 2X1, the middle hole 2X2, or the small hole 2X3. Here, the CPU 101 determines the direction from the button insertion hole to be used closest to the initial button insertion hole to the initial button insertion hole and the angle between the button insertion holes, and determines the angle according to the angle and the direction. The second rotating plate 2X is rotated. As a result, the button insertion hole to be used is set at the discharge port 23a which is the second transfer position. For example, when the button insertion hole to be used determined based on the input button diameter is the small hole 2X3 and the initial button insertion hole is the large hole 2X1, the CPU 10
1 rotates the second rotary plate 2X counterclockwise by an angle α (45 degrees in this case).

On the other hand, the centripetal mechanism is controlled as follows. That is, the CPU 101 determines based on the input button diameter whether or not the button diameter is equal to or larger than a certain reference diameter, and when it is determined that the button diameter is equal to or larger than the reference diameter, the locking solenoid 10 is turned off. And As a result, the rotary link 8 is held at the leftmost position I1, and the inner circle of each positioning member 71, 72, 73 has the maximum diameter T1. When it is determined that the button diameter input by the CPU 101 is smaller than the reference diameter, the locking solenoid 11 is turned on and the rotary link 77 is moved to the intermediate position I.
2, the inner circle of each positioning member 71, 72, 73 has an intermediate diameter T2. By performing such control, it is possible to correspond to three or more types of buttons.

[0025]

As described above, according to the present invention, after the buttons are conveyed onto the opening / closing plate by the first and second rotating plates, the center of the button is set on the opening / closing plate by the centripetal mechanism. In a button supply device adapted to match a predetermined set point, a plurality of types of button insertion holes having different diameters are formed at various intervals on the second rotating disk, and the button is instructed by an input means. By stopping the button insertion hole corresponding to the button diameter at the second delivery position and controlling the drive means for driving each positioning member of the centripetal mechanism in accordance with the instructed button diameter. Since the initial setting position of the positioning member is changed to inside and outside, even if the button diameter that should be frequently transported is changed due to high-mix low-volume production etc., it can be easily adjusted without changing the parts. Can be realized transport operation, it is possible to obtain an excellent versatility.
