[0014] In addition, before being glued, the rubber string 2 is cut and glued to form a ring shape. The resulting product is called and defined as a hair tie 10.
[0015] Also, the hair elastic is fed from the elastic cutting section 5 to the hair elastic manufacturing device main body 8 on the left side of the device. The side where the rubber cord is bonded is the rubber cord supply side 13, which is on the right side of the device from the rubber cord cutting section 5. The side to which the rubber cord is attached is called and defined as the rubber cord adhesive side 14.
[0016] [1. Configuration of a hair tie manufacturing device according to one embodiment of the present invention] First, the configuration of a hair elastic manufacturing device according to one embodiment of the present invention will be described. The hair elastic manufacturing device according to the embodiment automatically shortens the hair elastic that is completed by joining elastic cords into a ring shape. It is a device that can be mass-produced in a short time.
[0017] A side view of the hair tie manufacturing apparatus is shown in Figure 1. Note that Figure 1 is a side view, and the second holding device 9, hair tie moving device 11, conveyor 12, etc., are connected to the second gripping device 9 and the hair tie moving device. Other devices that perform the function of moving the station 11 and a motor that performs the function of rotating the conveyor of the transport conveyor 12 and the like are provided on the rear side of each device.
[0018] First, in Figure 1, the work process changes from the bottom left of Figure 1 to the bottom right of Figure 1 and then to the top right of Figure 1. The hair elastic is manufactured through the above-mentioned process. 8 is a rubber string supply and guide section that collects the rubber string 2 from the rubber ball 1 toward the device body. Here, the rubber cord 2 is a thin and long rubber core (for example, a cross-sectional shape The shape is a rubber having an elongated structure with a roughly circular structure of about 5 mm in diameter, for example, black The covering material such as wool is already wrapped around the rubber ball 1. It is a collection of rubber bands 2 arranged and gathered in a ring shape. From the rubber ball 1, the end of the rubber string 2 of the rubber ball 1 is pulled, for example, The device is set on the guide section 3.
[0019] When the rubber string 2 is hung from the rubber ball 1 to the rubber string supply guide portion 3, the rubber ball 1 and the rubber string supply guide portion 3 are In the middle of the guiding section 3, for example, a frame with a small ladder-like partition is provided, By inserting each rubber string 2 into each frame of the frame, each rubber string 2 is entangled. It may also be in an ugly form.
[0020] The number of such rubber balls 1 is, for example, ten in one embodiment. Ten rubber bands 2 are placed at a time in the guide section 3. In this case, one cycle of the hair tie manufacturing process is The number of hair ties that can be produced at one time is ten, and the hair ties are connected to the hair tympanic ball 1. The number of rubber bands (the number of rubber bands 2 hung on the rubber band supply guide part 3) and the number of hair ties that can be produced at one time are the same. I will.
[0021] Next, a more detailed structure of the hair elastic manufacturing device main body 8 is shown in Figure 2. The left side of the device body 8 will be described. First, the elastic cord supply guide unit 3 is a first elastic cord supply guide. It is composed of an auxiliary portion 22, a first clamping plate 33, a second clamping plate 34, a third clamping plate 35, etc. Among these, the first clamping plate 33 and the third clamping plate 35 are connected via bolts and nuts, The second clamping plate 34 is sandwiched between the first clamping plate 33 and the third clamping plate 35. Here, the bolts connecting the first clamping plate 33 and the third clamping plate 35 are The bolt is fitted through a hole drilled at the top, the radius of which is slightly larger than the inner diameter of the bolt. The second clamping plate 34 moves to the front and rear of the device independently of the movements of the first clamping plate 33 and the third clamping plate 35. The second clamping plate 34 and the two first auxiliary elastic cord supplying parts 22 are connected to each other. They move as one.
[0022] The first auxiliary elastic cord supply section 22 has a structure in which a plurality of approximately U-shaped members are connected in the vertical direction. Therefore, one rubber cord 2 is inserted into the first auxiliary rubber cord supply portion 22 having a substantially U-shaped portion. By passing through the horn-shaped space 56, it becomes stable inside the hair elastic manufacturing device main body 8. The number of the U-shaped members of the first auxiliary elastic cord supply section 22 connected in the vertical direction is limited to 10 in one embodiment. The first auxiliary elastic cord supplying section 22 may be changed depending on the number of elastic cords 1. Two clamping plates 34 are provided in total, one near the left end of the device and the other near the right end of the device. There are.
[0023] Here, one rubber string 2 is inserted into each of the U-shaped spaces 56 of the first auxiliary rubber string supply section 22. After passing one wire through, the openings connected to the top and bottom of the U-shaped space 56 are enclosed with, for example, a vinyl string. By preventing each of the rubber strings 2 from protruding from the U-shaped space 56, operational errors can be prevented. This may be an aspect that prevents this.
[0024] Then, the elastic cord 2 is fed from the left side of the device to the right side of the device through the elastic cord supply side 13 of the hair elastic manufacturing device main body 8. When the elastic cord 2 is conveyed to the left side of the hair elastic manufacturing device main body 8, the elastic cord supply and guide unit 3 guides the elastic cord 2 to the left side of the device main body 8. The rubber string supply guide unit 3 moves to assist the transport from the side to the right side of the device. First, the first clamping plate 33 and the third clamping plate 35 move together toward the rear of the device. The second clamping plate 34 is not completely fixed to the first clamping plate 33 and the third clamping plate 35. Therefore, the second clamping plate 34 and the third clamping plate 35 are not influenced by the movements of the first clamping plate 33 and the third clamping plate 35. The first clamping plate 33 and the third clamping plate 35 move separately. By moving the third clamping plate 35 to the rear side of the device, the second clamping plate 3 which does not move with the third clamping plate 35 The width between the second clamping plate 34 and the third clamping plate 35 narrows, and the rubber string 2 is clamped in a tensile state between the second clamping plate 34 and the third clamping plate 35. This will be the case.
[0025] Here, the second clamping plate 34 is provided at both the left and right ends with a first auxiliary elastic cord supply portion 22. Therefore, the first auxiliary elastic cord supply portion 22 is in tension between the second clamping plate 34 and the third clamping plate 35. Therefore, the rubber cords 2 connected in the vertical direction are less likely to become entangled. It is.
[0026] Further, although details will be described later, the rubber cord 2 is clamped by the second clamping plate 34 and the third clamping plate 35. The pressing of the front pressure plate 36 and the rear pressure plate 37 is performed approximately one second before the pressing of the front pressure plate 36 and the rear pressure plate 37. With the rubber cord 2 clamped in the induction section 3, the cutting section press heating device 4 presses it. Therefore, the elastic cord supply and guide unit 3 assists the cutting unit press and heat device 4 in pressing the elastic cord accurately.
[0027] Then, the second clamping plate 34 and the third clamping plate 35 clamp a part of the rubber string 2, The entire string supply and guidance unit 3 moves to the vicinity of the cutting section pressure and heating device 4 on the right side (elastic string guidance means). By repeating this operation, the elastic band 2 is fed to the elastic band supply unit 8 of the hair elastic manufacturing device. In this case, the first auxiliary elastic cord supply section 22 and the second auxiliary elastic cord supply section 23 can be supplied to the side 13. Since the rubber cord is sufficiently anchored at the auxiliary portion 23, the rubber cord 2 is entangled in the vertical direction. That doesn't happen.
[0028] Then, the elastic cord supply and guide unit 3 carries the elastic cord 2 to the vicinity of the cutting section press heating device 4, and then The first clamping plate 33 and the third clamping plate 35 move toward the front side of the device. 4 moves to the front side of the device without being influenced by the movements of the first clamping plate 33 and the third clamping plate 35. Therefore, the width between the second clamping plate 34 and the third clamping plate 35 is increased, and the rubber The string 2 is released from the tightened tension state (clamp release means). With the elastic cord supply and guide unit 3 in a released state, it moves to the left side of the device and returns to the original position. It moves to the left side of the elastic cord supply base 24, which is its home position (initial position return means), The rubber cord 2 is fixed in place by the same mechanism as above. By repeating the above steps, The supply and guide section 3 conveys the elastic bands 2 one after another to the elastic band bonding side 14 of the hair elastic manufacturing device main body 8. do.
[0029] The above-mentioned transport operation of the rubber string 2 is performed in accordance with the timing of cutting the rubber string 2 at the rubber string cutting section 5. It is in sync with Gu.
[0030] Next, as a structure of the hair elastic manufacturing device main body 8 near the elastic cord cutting section 5, each elastic cord 2 is cut one by one. The elastic cord is hung on the second auxiliary elastic cord supply section 23. The second auxiliary elastic cord supply section 23 is It has a similar configuration to the first auxiliary supply section 22 and has a structure in which a plurality of approximately U-shaped members are connected in the vertical direction. Therefore, the U-shaped space 57 formed by the approximately U-shaped member of the second auxiliary elastic cord supply section 23 Each rubber band 2 can be attached to each one. Therefore, at the elastic cord supply side 13 of the hair elastic manufacturing device main body 8, the elastic cords 2 may become tangled with each other. This prevents the rubber cord 2 from being broken and allows stable supply of the rubber cord 2.
[0031] In addition, the installation of the second auxiliary elastic cord supply unit 23 near the elastic cord cutting unit 5 of the hair elastic manufacturing device main body 8 A cutting section pressurizing and heating device 4 is provided near the left side of the device. The device is made up of two roughly rectangular metal plates, and the metal plate located at the front of the device is pushed forward. The pressure plate 36 and the metal plate located at the rear of the device are called rear pressure plate 37.
[0032] Then, the cut portion pressing and heating device 4 presses a part of the rubber string 2 against the front pressing plate 36 and the rear pressing plate 3 7 is a portion that presses the rubber string 2 by pinching it. When cutting the rubber cord 2, in order to prevent the braided cord at the cut portion of the rubber cord 2 from coming undone, This is to apply pressure in advance to the rubber cord cut-off portion 15, which is the area that will be cut off.
[0033] Here, in order to sufficiently press the rubber string 2, the rubber of the front pressing plate 36 and the rear pressing plate 37 The surface of the string 2 may have a finely uneven shape.
[0034] Next, regarding the device provided near the elastic cord cutting section 5 of the second auxiliary elastic cord supply section 23, 3. In the vicinity of the left side of the second auxiliary elastic cord supply section 23, in order from the left side of the device, The apparatus is provided with a string fixing device 41 and an elastic string cutting section 5. The elastic string cutting section 5 is provided with a The hair rubber band 2 is attached perpendicularly to the front-rear axis of the rubber band 2, i.e., perpendicular to the front-rear axis of the rubber band 2. Two cutting blades 42 are arranged parallel to the front and rear axis connecting the front and rear sides of the main body 8 of the device. is provided.
[0035] The cutting blade 42 has a cutting edge 42 facing the rubber cord passage side 47 where the rubber cord 2 is provided. The cutting edge 64 is provided in the vicinity of the end of the hair tie making device 8 so as to be parallel to the vertical axis of the device. Then, two cutting blades are used to cut the elastic cord 2 hung on the elastic cord fixing device 41. 42 is clamped perpendicular to the longitudinal direction of the rubber string 2 from the front and rear sides of the device, so that the rubber string 2 is The cutting is performed on a plane perpendicular to the direction.
[0036] Here, the cutting blade 42 is connected to the level of the other nearby connecting members (not shown) arranged in the front-rear direction of the device. Therefore, the cutting blade 42 moves along the rail portion, and It is possible to switch between the connected and disconnected states.
[0037] In one cutting mode, the cutting blade 42 on the front side of the device is first brought close enough to the rubber string 2, and then The cutting blade 42 on the rear side of the device is brought close to the rubber cord 2 from the rear side of the device, and the rubber cord 2 is cut. In this case, the cutting edge 64 of the cutting edge 42 may only be provided on the rear side of the device.
[0038] In one embodiment, the cutting blade 42 is driven by a piston or the like connected to the cutting blade 42. This switches between the open and closed states.
[0039] In addition, the elastic cord 2 is fixed by an elastic cord fixing device 41 before being cut by the elastic cord cutting unit 5. The elastic cord fixing device 41 is arranged perpendicular to the horizontal plane and perpendicular to the elastic cord 2 being supplied. These two rubber bands are arranged so that The string fixing plate 58 has an uneven surface facing the rubber string passage side 47. The rear facing elastic cord fixing plates 58 sandwich the elastic cord 2 from the front and rear. The rubber string 2 is hung in the recessed space formed by the recesses of 58. The recessed space formed by the recesses of the string fixing plate 58 is slightly smaller than the cross section of the rubber string 2. Therefore, the elastic cord 2 can be moved by the recessed space of the two elastic cord fixing plates 58 at the front and rear. The rubber cord 2 is firmly fixed in an immovable manner and is cut while in this fixed state.
[0040] When the rubber cord 2 is cut, the rubber cord cutting section 5 is provided at the upper part. The second gripping device 9 descends and grips and fixes the elastic cord 2. The second gripping portion 21 of the second gripping device 9 is As shown in FIG. 3, the second gripping portion 21 has an uneven portion on the opposing surface. Therefore, after the second gripping parts 21 are lowered on both sides of the elastic cord 2, the two second gripping parts 21 are pressed against each other. By operating to approach the rubber string 2, the rubber string 2 can be grasped from the front and rear sides of the device. In this way, with the second gripping portion 21 gripping and fixing the rubber cord 2, the rubber cord cutting portion 5 The cutting blade 42 moves vigorously towards the rubber cord 2 and cuts the rubber cord 2. After the string 2 is cut, the second gripping device 9 continues to grip the end of the rubber string 2 before moving on to the next step.
[0041] In addition, a rail base is provided at the bottom of the hair elastic manufacturing device main body 8 on the elastic band bonding side 14.

Then, the second clamping member of the elastic cord supply and guide unit 3 The elastic band 2 is held by the plate 34 and the third clamping plate 35 at the elastic band supply side 13 of the hair elastic manufacturing device main body 8. The material is transported from the rubber band adhesive side 14 (Fig. 2). do.
[0053] In addition, near the left side of the rubber cord cutting section 5 on the rubber cord supply side 13, the cutting section pressurizing and heating device 4 When pressing the rubber cord 2, first, This is the part where the string 2 is carried from the left side of the device to the right side of the device, where it stops and presses against the rubber string 2. Then, the rear pressure plate 37 is fixed in place without moving. Only the front pressure plate 36 faces the rear side of the device, i.e., the rear pressure plate 37 side, and is horizontal to the ground surface. Then, the rear pressure plate 37 becomes the receiver, and the rubber string 2 moves in the direction of the rear pressure plate 37. It is sandwiched and pressed between the front pressure plates 36 (compression movement).
[0054] Then, the rear pressure plate 37 moves to the upper side of the device, and the front pressure plate 36 moves to the lower side of the device. The rear pressure plate 37 and the front pressure plate 36 start moving at the same time. The moving speed is also the same. Then, after moving about 10 mm in the vertical direction, Each of them moves in the opposite direction at the same speed as before. The side pressure plate 37 moves downward, and the front pressure plate 36 moves upward. The upper end of the pressure plate 37 and the upper end of the front pressure plate 36 are moved to approximately the same height position. Stop moving at the same height.
[0055] Then, after the front pressure plate 36 and the rear pressure plate 37 return to the same initial height position, The pressure plate 36 moves toward the front of the device (i.e., away from the rubber band 2) by about 10 mm. The pressing process is completed by moving the object back and forth and then resting it in the original position before pressing (end of reciprocating movement). The time required for this pressing process is the time from when the front pressing plate 36 starts to move to the rear of the device to when the front pressing plate 36 starts to move to the rear of the device. The time it takes for the pressure plate 36 to return to the predetermined position at the front of the device is about 1 second. In this process, the front pressure plate 36 and the rear pressure plate 37 of the cut portion press heating device 4 are sufficiently preheated. After heating, the rubber cord cutting portion 15 of the rubber cord 2 is pressed, and the rubber cord cutting portion 15 of the rubber cord 2 is cut. It may also be configured to be able to sufficiently prevent fraying of the cut portion when the intended portion 15 is cut. In addition, the front pressure plate 36 and the rear pressure plate 37 are synchronized in the vertical direction by the rubber as described above. The rubber cord cutting portion 15 of the rubber cord 2 is not limited to one cycle per one location, 15 It is also possible to perform pressing by the cut portion pressing and heating device 4 for multiple cycles per location. stomach.
[0056] Next, the detailed process of making a hair tie will be described. In the following explanation, the area around the cut part 5 of the hair tie will be The moment when the rubber band 2 is gripped is assumed to be the start of one cycle of hair tie manufacturing. Thereafter, the rubber cord 2 is pulled for the first time while being held.
[0057] Next, in the vicinity of the elastic band cutting section 5, from the left side of the hair elastic manufacturing device main body 8, elastic bands are The second auxiliary supply unit 23, the rubber cord cutting unit 5, and the cutting blade 42 are provided (FIGS. 2 and 3). In addition, in order to stretch the rubber, the first gripping device 6 is attached to the right side of the device together with the first gripping part 43. When the elastic cord 2 is clamped, the elastic cord supply second auxiliary part 23 First, the first gripping portion 43 of the first gripping device 6 grips the first elastic band of the elastic band 2. The operator moves to the vicinity of the rubber cord cross section 60 and grasps and holds the vicinity of the first rubber cord cross section 60 of the rubber cord 2 (FIG. 10 , step S2). The mechanism of gripping at this time is in the vicinity of the first rubber cord cross section 60 of the rubber cord 2. , the first gripping device 6 has two first gripping parts 43 on the left side of the first rubber cord cross section 60. The string 2 is moved so as to be gripped at the front and rear sides of the device, and the string 2 is gripped by the recesses of the two first gripping portions 43 of the first gripping device 6. The rubber strings 2 fit into each of the gaps formed by the gaps.
[0058] Then, in a state where the first gripping device 6 grips the rubber cord 2, the adhesive application device 51 is Then, the first gripping device 6 moves to the left side of the device and grips the rubber string 2 together with the first gripping part 43 (FIG. 4 10, and step S2). The gripping position of the gripping part 53 of the adhesive applying device 51 is set to the first gripping position. The adhesive application device 51 is located near the upper end of the first gripping portion 43 of the gripping device 6. While holding the handle 43, move the hair elastic manufacturing device body 8 to the right side of the device on the elastic adhesive side 14. That is, the elastic cord 2 is held by the first holding portion 43 of the first holding device 6 and the adhesive application device 51. The wire is then gripped twice by the gripping parts 53 and pulled once towards the right side of the device (see FIG. 10, step S3). In addition, in the case where the tension is performed only by the first gripping portion 43 of the first gripping device 6, However, the adhesive of the adhesive exposure portion 52 of the adhesive application device 51 may be applied to the first rubber string cutter. The subsequent step of adhering to surface 60 provides a double grip.
[0059] Here, the rubber cord 2 is passed through the first holding device 6 and the holding portion 53 of the adhesive application device 51, On the elastic band adhesive side 14 of the hair elastic manufacturing device body 8, the hair elastic is pulled twice from the left side of the device to the right side of the device. The tension is performed separately (hereinafter, such tensions are referred to as the first tension and the second tension). The first pull of the elastic cord 2 to the right side of the device is the total movement (the hair elastic cord to be manufactured). The second pull is approximately 80% of the total length of the wire (equivalent to the total circumference of one wire). This is a movement of approximately 20% of the total length of the movement.
[0060] Then, the first tension (FIG. 10, step S3) and the second tension (FIG. 10, step S 5) A tensile blank of approximately 1 second is set as the interval between the two tensile tests. During this stretching blanking, the front pressure plate 36 and the rear pressure plate 37 are The rubber band 2 is pressed by the pressure sensor 37 (FIG. 10, step S4). Since the part corresponds to the part to be cut in the later process, the part to be pressed is designated as the part to be cut. This mechanism is used to perform tensioning in two steps, so after the first tensioning, The pressed part of the rubber cord 2 during the ranking is on the right side of the rubber cord cut part 5 after the second pulling. In other words, the cutting blade 42 is positioned in the vicinity of the cutting blade 42. The cord 2 is cut appropriately at the cut-off portion pressed by the cutting portion pressing and heating device 4. become.
[0061] Furthermore, until the first gripping by the first gripping portion 43 of the first gripping device 6 is performed, the elastic cord 2 is fixed by the elastic band fixing device 41 (FIG. 4), but the first gripping part 4 of the first gripping device 6 3 by the gripping part 53 of the adhesive application device 51, The two plates that make up 1 move away from the rubber band 2, that is, towards the front and rear of the device. The elastic cord 2 is loosened from the elastic cord fixing device 41. , the elastic cord 2 is released from the fixed state by the elastic cord fixing device 41 and is in a relaxed state. Therefore, it is easily stretchable.
[0062] In addition, in the tension blank between the first tension and the second tension, the rubber cord adhesive side 14 Then, adhesive is applied to the cross section 60 of the first rubber string (FIG. 10, step S5). The adhesive is applied by pulling the rubber cord 2 once, and the rubber cord 2 is pulled out by the first pulling. The adhesive application device 51 is held by the first holding portion 43 of the adhesive application device 51 and the holding portion 53 of the adhesive application device 51. Then, the gripping portion 53 of the adhesive applying device 51 grips the tip of the first gripping portion 43 of the first gripping device 6. While holding the adhesive application device, the connection part 55 of the adhesive application device main body 7 is moved from the right side of the device to the left side of the device in approximately 3 By moving the adhesive 52 to the cross section of the first rubber cord, Then, for about one second, the first rubber string cross section 60 and the adhesive on the adhesive exposed portion 52 are in contact with each other. After the adhesive application device is tightly attached, the connecting portion 55 moves from the left side of the device to the right side of the device, and the adhesive application device main body 7 However, the adhesive application device main body 7 returns to the predetermined position before the movement. The required time allows the adhesive to be sufficiently attached to the first rubber cord cross section 60 .
[0063] Then, the adhesive applicator main body 7 is returned to the predetermined position before the adhesive applicator main body 7 was moved. Immediately after the adhesive application, the first gripping portion 43 of the first gripping device 6 is gripped by the gripping portion 53 of the adhesive application device 51. While holding the adhesive, the adhesive application device 51 moves from the left side of the device to the right side of the device, and the second application of the rubber string 2 The tension is applied (FIG. 10, step S5).
[0064] Then, at the same time as the second pulling of the rubber cord 2 begins, the second gripping device 9 descends from above. Then, by the time the second pulling is completed, the second grips will be placed on both sides of the rubber band 2. The second gripping portion 21 of the gripping device 9 is on standby and ready to grip the elastic cord 2 (FIG. 5). The portion where the second gripping portion 21 of the second gripping device 9 grips the elastic cord 2 is near the elastic cord cutting portion 5. be.
[0065] After the second pulling is completed, the elastic cord fixing device 41 of the elastic cord cutting portion 5 is first The two fixing plates that make up the device move towards the rubber string 2 from the front and rear of the device, respectively, and hold the rubber string 2 firmly. Then, the sensor is firmly fixed in place (FIG. 10, step S6).
[0066] Next, the second gripping units 21 of the second gripping devices 9, which had been waiting on either side of the rubber string 2, The elastic cord 2 is firmly gripped from both the front and rear sides and fixed (FIG. 5 and step S6 in FIG. 10). ).
[0067] Then, two cutting blades 42 move toward the elastic cord 2 in the front-rear direction of the device, respectively. The rubber string 2 is clamped by the blade surface portion 64 of the cutting blade 42 from the front and rear sides of the device, and the rubber string 2 is cut in the longitudinal direction. In this way, the rubber string 2 is cut in the vertical direction (FIG. 6 and step S7 in FIG. 10). When cutting, the elastic cord 2 is held by the fixing plate of the elastic cord fixing device 41 and the second holding part 21 of the second holding device 9. The fixing plate of the elastic band fixing device 41 and the second gripper are in a state of being firmly fixed and adjacent to each other. Since the cutting is performed between the second gripping portions 21 of the holding device 9, the elastic cord 2 does not loosen when it is cut. The string 2 can be cut cleanly without losing its shape.
[0068] Then, almost at the same time as the cutting process in step S7 is completed, the first gripping device 6 moves to the right side of the device. The hair then moves quickly from the left side of the device to the right side (Fig. 7). The movement distance is the length of one circumference of the hair tie. The length (i.e., the length of one cut piece) is approximately 20% of the total length. The position 6 waits for a while at that position. In other words, immediately after cutting, the rubber string 2 Since the distance from the cut end to the first gripping portion 43 of the first gripping device 6 is shortened, the cut elastic cord 2 is The bending occurs.
[0069] Then, the process moves to the step of bonding the rubber cord 2. First, the second holding device 9 While holding the rubber band 2 with the device 1, move the device horizontally to the right side by approximately 50 mm (Fig. 10, step The mechanism of this movement is that the hair tie manufacturing device body 8 is moved almost along the rail at the bottom right. The first holding device 6, which is on standby and holds one end of the elastic cord 2, The first gripping portion 43 and the second gripping portion 2 of the second gripping device 9 gripping the other end of the rubber cord 2 1 approach each other to a separation width of about 50 mm, the second gripping portion 21 of the second gripping device 9 and the first gripping portion 22 of the first gripping device 9 The first gripping parts 43 of the gripping device 6 simultaneously start their rotational movements (see steps 8 and 10). Top S9).
[0070] This rotational movement will be described in detail. This rotational movement is caused by the second gripping portion 2 of the second gripping device 9. 1 and the first gripping portion 43 of the first gripping device 6 start and finish rotating at the same time. First, the first gripping portion 43 of the first gripping device 6 is located at the center of the first gripping device rotating portion 45, which is its base. The rotation is centered on a plane parallel to the horizontal plane. The direction of rotation is the same as the clock direction when viewed from above the device. The first gripping portion 43 is arranged approximately 180 degrees around the first gripping device 6 and is located on the left side of the first gripping device 6 in a plan view. is positioned just to the right of the first holding device 6 at the opposite pole in plan view.
[0071] In addition, the second gripping portion 21 of the second gripping device 9 is connected to the second gripping device rotating portion 62 of the second gripping device 9. The center of the axis is the center point, and it rotates in a plane parallel to the horizontal plane. The direction of this rotation is approximately counterclockwise. The second gripping unit 21, which was located on the left side of the second gripping device 9 in a plan view, is now 180 degrees. The second holding device 9 is positioned on the right side of the opposite electrode.
[0072] Therefore, when the above rotational movement is completed, the first rubber of the rubber string 2 held by the first holding device 6 The rubber cord cross section 60 and the second rubber cord cross section 63 of the rubber cord 2 gripped by the second gripping device 9 are exactly opposite to each other. (FIGS. 8 and 9) Then, the first rubber cord cross section 60 is coated with the adhesive as described above. The process already provides a generous amount of adhesive.
[0073] Then, the first gripping device 6 and the first gripping portion 43 move from the right side of the device to the left side of the device, and the mm, and the first rubber cord cross section 60 and the second rubber cord cross section 63 are sufficiently bonded together (see FIG. 10, Step S9). The time for bonding the first rubber cord cross section 60 and the second rubber cord cross section 63 in this process is approximately 1 seconds.
[0074] After the bonding process is completed, the first gripping portion 43 of the first gripping device 6 is separated from the hair tie 10. That is, the two first gripping parts 43 of the first gripping device 6 move forward and backward, respectively. As a result, a space of approximately 50 mm is created between the front and rear first gripping portions 43. The hair elastic 10 is released from the first gripping portion 43 (FIG. 10, step S10).
[0075] Meanwhile, the hair elastic 10 remains held by the second holding portion 21 of the second holding device 9. Then, the second holding device 9 moves upward while still holding the hair elastic 10 with the second holding portion 21. Then, the hair tie 10 was handed over to the approaching hair tie moving device 11 (FIG. 10, step S1 0), it moves to just above the hair elastic manufacturing device main body 8 and waits for the next operation.
[0076] In addition, the first gripping device 6 having the first gripping part 43 that has released the hair elastic 10 is in the opposite direction to the previous one. (i.e., a 180 degree counterclockwise rotation as viewed from above the device) After returning the unit 43 to the position before the rotation, move the unit 43 from the right side of the device to the left side of the device on the rail unit 25. Then, the robot gets into position to grasp the next rubber band 2.
[0077] In addition, the hair tie 10 transferred to the hair tie moving device 11 is, for example, in one embodiment, The rubber is transferred onto a transfer conveyor 12 by a rubber transfer device 11 (FIG. 1).
[0078] In one embodiment of the hair tie moving device 11, the hair tie moving device 11 is configured as follows (not shown): At the tip of the slat, two rows of stake-like projections are arranged in a long shape. When the hair tie 10 is not held, the projections are arranged side by side in the short direction. Then, the second gripping unit 21 of the second gripping device 9 grips the bundles in the vertical direction. First, two rows of peg-shaped protrusions are inserted into the gaps between the hair ties 10 that are being held. After that, only one row of the stake-like protrusions is shifted halfway up and down, and the two rows of stake-like protrusions The hair tie 10 is sandwiched and held between the objects.
[0079] Then, while the hair tie 10 is held by the hair tie moving device 11, the hair tie moving device 11 is moved to another position. The hair tie 10 is moved onto the conveyor 12 provided at the location, and the holder of the hair tie 10 is After making it parallel to the conveyor surface of the conveyor 12 and bringing it close, the two rows of stake-like protrusions are again parallel to the short side. By setting the hair tie 10 in this state, the hair tie 10 is released from the holding part.
[0080] Here, the hair elastic moving device 11 is provided between the hair elastic manufacturing device main body 8 and the conveyor 12. The rails are connected to the connecting members, and the rails are repeatedly moved back and forth. Therefore, the hair ties 10 are intermittently transported from the hair elastic manufacturing apparatus main body 8 to the transport conveyor 12. This becomes:
[0081] The hair tie 10 is exposed to hot air for a certain period of time while moving on the conveyor 12. After undergoing drying treatment, the product is stored in a packing container and shipped. In one embodiment, a well-ventilated wire mesh sheet is placed on the surface.
