TECHNICAL FIELD The present invention relates to a device for attaching a fastener, in particular, with a fastener for selectively supplying a fastener (a fastener in the form of a male or female, its attachment member or a simple decorative fastener) to an attaching part to a cloth or the like. A device and a pusher device, a delivery device and a supply device.

Conventionally, one or more fasteners (ie, fasteners such as male and female fasteners of snap fasteners, or attachment members thereof, etc.) are attached to one or more hoppers when attached to the fasteners on cloth or the like. ) Was fed to the cloth attaching position between the top and the low stage mold, and attached to the cloth at that position. In such a fastener attaching device, the number of fasteners that can be supplied is determined by the number of hoppers, so that only the fasteners in the hopper are supplied, and when the type of the fasteners is changed, the amount of hoppers is also replaced. Should be.

In order to solve such a problem, the applicant has already provided a fastener attachment device having a three hopper method to Japanese Special Office 55-49163 (1980), in which the three hoppers are attached to one side (in this case, attachment). It is sufficient because the fastener of the member) can be used in common for the fastener of the other side (in this case, male and female fasteners), and the expansion to the four hoppers is easily realized when another attachment member is used.

1 through 3 illustrate the schematic of the apparatus shown in the publication described above, and FIG. 4 illustrates a schematic of the Faasner.

As illustrated in FIG. 1, the snap fastener is accommodated in a receiving member formed between the vertical plane of the device casing 2 and the rotating snap fastener receiver or hopper 1, and the guide plate 4, the track connection. Attachment position of the cloth 7 via the piece 5, the fastener feed track 6 and finally the direction adjusting groove 3 formed on the outer circumferential surface facing the device casing of the rotary hopper 1 at equal intervals. (That is, the position of the caulking mechanism). The rotary hopper is driven intermittently in the direction of the arrow, and the fastener dropped into the direction adjusting groove 3 by gravity while the groove is in the vertical lowest position is eventually discharged to the guide groove 8. The screw 9 is for fixing the fastener feed track 6.

As shown in Figure 2, three or more hoppers (three in the figure) are used. The fasteners to be supplied consist of male snaps 11, female snaps 10 and attachment members 12 and 13 (of the same size and shape), for example as shown in FIG. L-shaped support frames 23 and 24 are fixed to the support structures 20 and 21 fixed to the base member (not shown), and the horizontal shaft 31 is attached to the vertical portions 25 and 26, respectively. The pivots 33 are pivotally mounted, respectively, and are driven by the cranks 45 and 44 from the power source, respectively. The hopper 27 as shown in FIG. 1 is fixed to the horizontal axis 31, and the hoppers 29 and 30 are fixed to the horizontal axis 33. Corresponding to the fastener feed track 6 of FIG. 1, the track 56 in FIG. 2 faces the low end side (for low stage mold) at position K via the guide groove 28 in the hopper 27, The tracks 57 and 58 face the common track 59 via the guide grooves 34 and 32 in the hoppers 29 and 30, and the track 59 is the upper side of the position K (upper mold). Toward the dragon). FIG. 3 shows the form of the points of meeting of the tracks 57 and 58, where the switching piece 60 is pivoted to the pivot pivot mounting point 61 as the support point of the lever for switching the upper and lower stage tracks. For example, the male snap 11 is supplied from the hopper 29, the female snap 10 is supplied from the hopper 30, and the attachment members 12 and 13 are supplied from the common hopper 27. do. In the case where the attachment members 12 and 13 are different from each other, another hopper may be added to the hopper 27 to be used. In this case, structures similar to (57), (58) and (59) may be used in place of the track 56.

The fasteners 76, 77 coming in position K are attached to the push rods 72, 73 fixed to the slide block 71 supported by the guide 70, as shown in FIG. 5. By the upper mold 74 and the lower mold 75, respectively.

The problem with the conventional apparatus described above was that when the track was switched to change the type of fastener, a new operation could not be immediately executed because a few fasteners used in the previous process were filled in the track. Therefore, it is necessary to carry out switching at the track outlet, and the apparatus becomes complicated, and furthermore, such a switching device has to be switched every time the operation changes, thus losing the efficiency of operation.

Another problem was the low flexibility of the device according to the prior art. That is, it is preferable that the fastener attaching operation be able to arbitrarily use not only manual and semi-automatic but also automatic supply from the hopper, but could not provide a fastener attaching device that satisfies this request.

In the case of using two or more hoppers, an electric motor for rotating the shaft should be provided to each hopper, or two hoppers should be supported on the common axis of rotation thereof. A rotor is required, and in the latter case, an unnecessary hopper is driven, causing the powder to be caused by abrasion due to friction between the fastener and the hopper wall, contaminating the interior or fabric of the hopper at too early a stage. Moreover, in the form of using a common shaft, the width of the device becomes too large when three or more hoppers are required.

Moreover, in conventional devices, the power source is generally not remarkably matched to the ram, so that a long link such as link 64 is used as the power transmission device, but such a link is applied to a pushing force to transmit a pushing force. The cross section is sufficiently large so as not to be deformed, the weight becomes heavy and the inertia becomes large, thereby increasing the load of the power supply. Therefore, the purpose of minimization, light weight and energy saving could not be achieved.

Accordingly, it is an object of the present invention to provide a fastener attaching device capable of selecting tracks by automatic, semi-automatic and manual operation without including a special track switching device to realize a thorough improvement in operating efficiency.

It is another object of the present invention to provide a hopper device that can selectively drive one or more arbitrary hoppers while the other hopper is not in operation, in a parser attachment device using a plurality of hoppers, To solve the problem.

Still another object of the present invention is to improve the power transmission device to achieve miniaturization, light weight and power saving of the fastener attachment device.

The present invention, at least one hopper, a guide track extending from the hopper toward the lower end position, a guide groove extending horizontally toward at least one of the upper mold and the lower stage through the lower end outlet of the guide track, and the guide A push rod that slides in the guide groove so as to push at least one top mold and a lower mold from the track outlet, and a front end of the push rod stopped at a mold position further adjacent to the track outlet; Consisting of a power source coinciding with the rod and, when actuated, the power source retracts the matched push rod toward the trailing end of the track outlet from the pre-operation position and tops the matched push rod to stop at the pre-acting position. Or a fastener attachment device, characterized in that it is pushed by a low stage mold The.

According to this apparatus, the unnecessary outlet of the guide track outlet is closed by the stationary push rod, so that the undesirable pasner is kept in the track, and only two feeders are operated. Therefore, a special track switching device becomes unnecessary, and at the same time, unnecessary labor such as an operation of removing the fasteners at the time of switching is not necessary, and switching to other operations becomes easy. Moreover, the one or more feeders in the hopper or under the overall certainty of the situation can be stopped, so that the fasteners are supplied either fully manually or semi-automatically, increasing flexibility.

In another embodiment of the present invention, the fastener attaching device is configured to perform the fastener attaching operation by moving the movable top mold up and down with respect to the fixed bottom mold, and the fixed bottom mold sliding the vertical ram supporting the mold to the fixed base. Support freely, pivotally mount the lower end of the first link to the upper end of the ram, pivotally mount the lower end of the second link to the other end of the first link, and pivot the upper end of the second link to the fixed base. Pivotally mounted so as to contract and expand both links in a &lt;-&gt; shape so that the ram generates vertical motion, couple one end of the first tension link to the pivot pivot mounting point of the both links, and connect the other end of the first tension link. An output coupled to one leg of the swing link pivotally mounted on the fixed base, one end of the second tension link to the other leg, and reciprocating the other end of the second tension link The tension of the second tension link in the tensioning process of the power source pushes the first tension link so that the first and second links expand in a linear form in a <-form to perform the fastener attaching process. It is characterized by.

According to this type of device, since the long link in the power transmission device of the fastener attachment device receives only the tension during the ram process of applying the attachment pressure, weight reduction of the link is achieved, thereby achieving the object of the present invention. In other words, it can be seen that a short link, that is, a power transmission device such as a crank or the like, accommodates tensile force and shear force without any problem.

In still another aspect of the present invention, a plurality of rotary hoppers for supplying a fastener, a guide track extending from the hopper toward the low unit value, and a guide extending horizontally toward the upper and lower stage molds through the low end outlet of the guide track. A groove, a push rod sliding in the guide groove so as to supply a fastener coming from the guide track outlet to the upper and lower stage molds, and a power source reciprocating the push rod, wherein the hopper is interposed with a transmission means. Driven by one or more reversible electric motors, said reversible motors and said transfer means driving one or more arbitrary hoppers by selection setting means. To provide. In a representative example, two reversible motors and four hoppers were used, each reversible motor coupled to the shaft of a pair of hoppers via a transfer means. The transmission means is adapted to drive only one of a pair of hoppers each motor is built in by matching the hopper shaft via a unidirectional clutch. Therefore, any one hopper for the upper mold, a combination of any one hopper for the lower mold, or two specific hoppers for the upper and the lower mold can be set by the selection setting means.

According to this invention, the drive device of a hopper becomes simple and it is possible to use with flexibility at the same time. For example, a four-hopper unit, overall manual operation by stopping all hoppers, and semi-automatic operation (using one of the upper or lower stage molds) by using a single hopper in four ways using one motor rotation in one direction. In the above representative example describing manual feeding of fasteners, the use of the top and low stage hoppers is enabled by four methods (overall automatic operation) by using both motors.

The invention is described in detail below with reference to the embodiments shown in the drawings.

(1) the leap of the whole form

6 to 8 illustrate an example of the fastener attaching apparatus by the four-hopper method for implementing the present invention. Here, the base 80 is provided with a table 82 for supporting the low stage mold and an upper frame 85 for supporting the vertical ram 84 for the top mold. Both sides of the base 80 constitute a parallel vertical plane, and the portions of the upper frame 85 are divided into four hoppers 86, 87, 88, and ( 89, the hoppers 86, 87 are simultaneously rotated oppositely by the motor 90 and the delivery means (not shown), as shown in the figure, and the other hoppers 88, 89 ) Is likewise reversed by the motor 91 and the delivery means (not shown). The fastener guide tracks 92, 93, 94 and 95 extend downward from the hoppers 86, 87, 88 and 89, respectively, so that the horizontal guide grooves 96, 97 and 98 are ) And (99), respectively, horizontally to form the outlet of the fastener. Push rods (to be described later) are fitted in the guide grooves 96, 97, 98, and 99 so that they slide horizontally, respectively, and are supplied to the upper and lower stages from the guide tracks 92 and 95, respectively. Push the fastener (general name for the male and female snap and the same attachment).

(2) push rod device

9 and 10 illustrate portions relating to the subject matter of the present invention. Push rods 100, 101, 102, and 103 are fitted into the guide grooves 96, 97, 98, and 99, respectively, and the rear end of the push rod constitutes a piston to form a hydraulic cylinder 104. Are operated horizontally by 105, 106 and 107, respectively. Each pushrod forms a protrusion 110 that is in contact with the operator 109 of the stop switch 108 (the figure illustrates only for the pushrod 102). Push rods 100, 101, 102 and 103 are retracted so that the front ends of these rods are located in the guide tracks 111, 112, 113 and 114 as shown in FIG. When it comes to the position to close the exit, this switch means in action acts to stop the push rod. The stop switch 108 is rocking, and forms a working passage of the protrusion 110 when the cylinder is forcibly applied. The cylinders 104, 105, 106 and 107 are optionally configured by actuating the button 115 of the operating plate (FIGS. 6 and 7), the one consisting of a pair of top and bottom ends. When the selected cylinder retracts from the stop position described above during operation, the discharge holes of the guide tracks 111, 112, 113, and 114 are opened to release the fasteners 10 to 13; Thereafter, the feeder is advanced and supplied to the support recesses 116 and 117 of the molds 81 and 83, and then the stop switch 108 retreats and stops at the same stop position as described above. This operation may be performed by an appropriate electrical device.

(3) Power trains for glass systems.

The vertical ram 84 for the upper mold is pivotally mounted to the link 118 at the top, and the link 118 is pivotally pivoted to the lower end of the link 119 pivotally mounted to the fixed shaft 120 at the top. Is mounted. Therefore, the links 118 and 119 may generate a stretchable operation to move the ram 84 up and down. That is, the shaft 121 in which the links 118 and 119 are pivotally mounted is the lower end portion 125 of the crank 124 pivotally mounted to the fixed shaft 123 by the elongated metal rod link 122. It is coupled to the front end of the), and expands and contracts by the rotation of the crank 124. An elongated metal road link 127 is coupled to the front end of the upper end portion 126 of the crank 124, and the other end of the elongated metal road link 127 is coupled to the annular slide race 128. The circular shaft 129 slides into this base freely, and the circular shaft 129 is fixed to the motor shaft 130 in an eccentric position. This motor executes each downward movement of the upper mold, ie actuated by the respective pedal actuation (in some situations, the engagement of the lower stage is allowed). It can be seen that the motor can only be operated when the push rod is in the retracted position. When the motor is actuated, the power can lower the ram 84 only by the actuation of the tension of the metal road links 127 and 122, while the pushing force is applied to the metal road link while the ram is up, but the force is less. Therefore, this link form is excellent.

(4) hopper device

The hoppers 86 and 87 are operated by the motor 90 and the hoppers 88 and 89 are respectively operated by the motor 91 in the direction of the arrow. Until now, the hopper was installed along the same axis as shown in FIG. 2, but this installation made the device wider, especially in a four-hopper device. The device of the present invention has a thin shape as illustrated in FIGS. 16 and 17. In this figure, the V-belt pulleys 203 and 204 are fixed to the inner ends of the output shafts 201 and 202 of the motors 90 and 91, respectively, and the endless V belts 205 and 206 are fixed. Power is transmitted to the hoppers 86, 87, 88 and 89 via the intervening power. Hoppers 86, 87, 88 and 89 have shafts 207, 208, 209 and 210, respectively, with respective input ends of one-way clutches 211, 212, 213 and ( 214). As illustrated in FIG. 17, the clutch is engaged to drive the hopper 86 counterclockwise, the hopper 87 clockwise, the hopper 89 from the outside and counterclockwise. Not combined. For example, each clutch may constitute an inner ring 215 of the brake having a groove for the V belt 205 or 206, such that power is selected from the motors 90 and 91 and the selected motor. The selection of the rotational direction of causes the operation of one or more of the arbitrary hoppers.

As such, selection and switching of the hopper can be arbitrarily obtained by controlling only the motor. Due to two motors and two directions, four selections of single hoppers, four selections of hoppers for the upper and lower molds (hoppers for the upper mold 2 × hoppers for the lower mold 2 = 4) and a total stop or nine choices Become. As such, the operation of the plurality of hoppers can be controlled by using a reverse motor, and arbitrary use of manual, semi-automatic and fully automatic is realized by simple switching. Since the selection of the motor setting is performed by the operation button 115, contamination of the hopper due to powder generation can be suppressed to a minimum value.

(5) action

The operation of the device having the form described above is as follows. If the motor shaft 130 is stopped at the position of FIG. 9 at the stop position of the push rod, first, the upper and lower stage molds 83 and 81 are selected according to the kind of fasteners, and are set at predetermined positions. , Horizontal guide grooves (96) ~ (99) is determined. In the figure, the upper mold 83 corresponds to the guide groove 98 and the lower stage 81 corresponds to the guide groove 99. Buttons 115 (6 and 7) of the operating plate are set to select corresponding pairs of upper and lower stage molds and cylinders corresponding thereto. In FIG. 9, there are push rods 102 and 103 and corresponding cylinders 106 and 107, respectively.

Since the operation starts with the main switch of the working plate, the motors 90 and 91 start to feed the fasteners from the hoppers 86 to 89 to the guide tracks 92 to 99, and the fasteners It is supplied to the low end discharge port of the guide tracks 111, 112, 113, and 114. The push rod is initially in the rest position (Fig. 10), but the selected cylinder (106 and 107 in this embodiment) acting simultaneously or continuously with the start of the motors 90 and 91 starts retreating. And, the fasteners come from the discharge ports 113 and 114 to the horizontal guide grooves 98 and 99, but are blocked by the push rod because the other cylinders are at rest. The hydraulic pressures of the cylinders 106 and 107 are reversed, and the push rods 102 and 103 which push the fasteners 12 and 10 into the recesses 117 and 116 of the upper and lower stage molds are respectively automatic. Reverses and stops at the operating position of the switch 108.

Then, when the pedal (not shown) is pressed, the motor shaft 130 starts to operate, and mainly transmits a tensile force to the links 119 and 121, so that the ram 84 descends, and the fastener 10 (12) is attached to a predetermined fabric inserted between the upper and lower molds. The motor shaft eventually terminates the parting cycle returning to the position illustrated in the figure.

If semi-automatic operation is required, only the work feeder of the hopper 88, guide track 94 and guide groove 98 is operated before starting the fastener attachment operation, and the feeder is manually supplied to the low stage mold. . The operation process will be understood from the above description.

Moreover, it is also possible to stop all fastener feeders in order to realize manual feed on both the top and low stage molds.

Another embodiment will be described with reference to FIG. This figure is basically the same as the above-described embodiment except that the number of power sources and supply devices is different. That is, the acting rod 200 pivotally mounted on the fixed shaft 123 used in place of the piston cylinder-type hydraulic cylinders 104, 105, 106 and 107 illustrated in FIG. The trailing ends of the push rods 207 and 208 of the horizontal guide grooves 205 and 206 coupled to the outlets 203 and 204 of the 201 and 202, respectively. A slot 209 is formed near the top of the action rod 200 so that the pin 210 fixed to the swing crank 124 operated by the tension link 127 of the elongated metal rod link of the power source transmits power. Is fitted. The rear ends of the push rods 207 and 208 respectively include pins 211 and 212 which can be retracted in the axial direction, and the actuating rod 200 accommodates the pins 211 and 212 so as to be attached therein. To the corresponding elongated slots 213 and 214.

FIG. 12 is a plan view illustrating the action means of the pins 211 and 212. The stop position detecting means 108 and 109 shown in FIGS. 9 and 10 and the stop switch 217 which is a swing detection means are shown in FIG. Corresponds to the instantaneous state at the start of operation, where the push rod 208 (or 207) closes the outlet 203 or 204 of the guide track 201 or 202. The rear end of the pin 211 is formed of at least a magnetic material, and the push rods 207 and 208 are formed with recesses 216 that are movable in the direction of the axis where the pins 211 and 212 are fixed, respectively. do. At the stop positions of the push rods 207 and 208, the electromagnetic attraction operator 215 is provided at the positions lining the pins 211 and 212, respectively.

The operation of this fastener attachment device is substantially the same as in the first embodiment. Regarding the action of the push rod, instead of the piston cylinder, a common power source is used with the ram for the upper mold, and by the swing crank 124, the acting rod 200 is placed between the chain positions (first to the rear of the stop position) in FIG. Is pushed, the push rods 207 and 208 move correspondingly horizontally, and the actuation rod 200 stops when the stop switch 217 operates in the retraction stroke. If actuation is required, the push rod 207 or 208 or both rods are required to be stopped and the corresponding electromagnet attraction operator 215 is actuated. 13 illustrates a case where the push rod 208 is stopped. By the action of the operator 215, the pins 211 or 212 (or both rods) are extracted. In this way, that is, as shown in FIG. 13, the fastener is automatically supplied to the upper mold 83, and the manual feeding (directly supplied by hand) to the lower mold is possible. Also, in order to operate the stationary push rod, only nodules in the operator 215 circuit are required during the suspension of the actuation rod.

Example 3

14 and 15 illustrate a third embodiment in which the lower stage 81 is manually fed and the upper mold 83 is automatic and manually fed. Each member is the same as that for the upper mold of the second embodiment, and corresponding parts are simply attached to the same reference numerals in FIGS. 11 to 13, and further description is omitted. The action of the push rod 107 'in this embodiment is the same as in the previous embodiment.
