Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an assembly machine for inserting the slats of a blind into a ladder cord.

[Prior art] Conventionally, this type of blind assembly machine
There is an assembly machine disclosed in Japanese Patent No. 183474, which is equipped with an insertion device for inserting the slat material into the ladder cord, and a conveyance device for delivering the slat material to the insertion device.

The insertion device includes a lifting rod that is movable up and down so as to lift the slat material inserted through the ladder cord to a predetermined height position, a support member disposed near the lifting rod, and the support member. A pair of guide rods that are installed upright on the member and come into contact with both side edges of the slat material to guide the upward movement of the slat material when the slat material is lifted by the lifting rod, and when the slat material is lifted up. and a holding member that protrudes between both guide bars and can hold the slat material at a predetermined height.

Further, the conveying device is pressed against both sides of the slat material,
It is equipped with a pair of supply rollers that rotate to feed the slant material toward the insertion device, and a guide roller that guides the slat material between the two supply rollers. An annular guide groove is formed that abuts the edge.

[Problems to be Solved by the Invention] However, with the conventional conveying device and insertion device, although it is possible to convey slat materials of one width and insert them into the ladder cord, it is difficult to convey slat materials of other widths. The problem was that it could not be dealt with.

That is, since only one guide groove of a specific width is formed in the guide roller in the conveying device, if the width of the slat material is wider than this guide groove, the same slat material cannot pass through the guide groove. If the width is narrower than the guide groove, both edges of the slat material will not come into contact with the guide groove and will not be reliably guided between the supply rollers.

Furthermore, since the pair of guide bars on the support member in the insertion device are fixed, if the width of the slat material is wider than the gap between both guide bars, it cannot pass through, and if it is narrower than the gap between both guide bars, the slat material cannot pass through. In this case, both side edges of the slat material do not come into contact with each guide bar, and the slat material cannot be reliably guided when moving upward, and as mentioned above, the width of the slat material is If the slat material is narrower than this, the holding member may not be able to hold the slat material.

Therefore, when assembling multiple types of blinds using multiple types of slat materials with different widths, as many assembly machines as the number corresponding to the widths are required.

In addition, in the above-mentioned insertion device, when inserting the slat material between the two guide bars, there is nothing to guide the slat material between the two guide bars, so the tip of the slat material sent out from the supply roller is inserted into both the guide bars. There was a risk that it would not be possible to reliably enter the area.

An object of the present invention is to provide a blind assembly machine that can accommodate the widths of the slat materials with a simple operation even when assembling a blind using multiple types of slat materials having different widths.

[Means for Solving the Problems] Therefore, in order to achieve the above object, the blind assembly machine of the present invention is provided so as to be movable up and down so that the slat material inserted through the ladder cord can be lifted to a predetermined height position. a lifting rod; a support member disposed near the lifting rod; a pair of guide bars that guide the upward movement of the slat material; and a holding member that protrudes between the guide bars when the slat material is lifted to hold the slat material at a predetermined height; The guide rods are supported in a relatively movable manner so that the distance between the guide rods can be adjusted, and stop means are provided for positioning the guide rods.

Further, a biasing means is provided for biasing the holding member between both guide bars so that the holding member can follow the movement of the guide bar and protrude between the guide bars, and both guide bars are based on the biasing force. It is preferable to provide a stopper for regulating the amount of protrusion of the holding member into the gap.

Further, a slat guide member for guiding the two slat materials between the two guide bars is provided near the guide rod, and the slat guide member is provided with a slat guide member that is in contact with both side edges of the slat material. A plurality of guide grooves may be formed to guide the insertion between the two guide rods, and the widths of the guide grooves may be set to be different from each other.

The blind assembly machine of the present invention includes a pair of supply rollers that are pressed against both sides of the slant material and feed the slat material toward the insertion device by rotation, and a pair of supply rollers that contact both side edges of the slat material to feed the slat material to the insertion device. a guide roller that guides between both supply rollers; a plurality of annular guide grooves having mutually different widths and diameters are provided on the outer periphery of the guide roller; and one of these guide grooves is provided on both sides of the slat material. A moving means is provided for moving the guide roller in a direction toward and away from the slat material so as to come into contact with the edge.

[Function] In the blind assembly machine of the present invention, the slat material inserted through the ladder cord is lifted by the lifting rod while being in contact with the pair of guide rods on the support member. When the slat material is lifted, the holding member projects between both guide bars, and the slat material is placed on the protruding portion of the holding member.

By relatively moving the guide bars and positioning them using a stop means, it is possible to adjust the interval between the guide bars.

When the guide rods are relatively moved as described above, the holding member is urged between the two guide rods by the urging means, and
Since the amount of protrusion between the guide bars based on the biasing force is regulated by the stopper, the holding member protrudes between the guide bars following the relative movement of the guide bars.

By the way, when the slat material guides slat materials of different widths passing through the guide grooves of the slat guide member between the guide bars, before the slat material enters between the guide bars, the slat material A guide groove corresponding to the width is made to face the slat material.

Further, in the blind assembly machine of the present invention, the slat material is guided between the pair of supply rollers by passing while contacting the annular guide groove of the guide roller. A plurality of guide grooves are provided on the guide roller, so when slats of different widths pass, the guide roller is moved to overturn the slats by the moving means, and guide grooves of corresponding widths are formed on both sides of the slats. bring it into contact.

Note that a support protrusion 45a extending to the left is provided approximately at the center of the first lifting rod 45, and a support protrusion 45a extending to the left is located approximately at the center of the first lifting rod 45;
Support protrusions 47a extending to the right are integrally formed approximately at the center of each of the support protrusions 47a.

At the front end of the substrate 28, the first lifting rod 45
Support members 48 and 49 extending forward are fixed to a position near the left side of the third lifting rod 47 and a position near the right side of the third lifting rod 47, respectively. Recesses 48a and 49a are formed in the center of the upper surface of each support member 48 and 49, and the movable body 43
When the first and third lifting rods 45, 47 are moved downward, the supporting protrusions 45a, 47a of the first and third lifting rods 45, 47 are accommodated.

As shown in FIG. 5.6, a pair of attachment holes 50 are provided in the vicinity of the front and back of each of the recesses 48a and 49a in the support member 48 and 49, and a guide rod 51 is inserted into each attachment hole 50. The lower end is attached. Each support member 48.4
The distance between the pair of guide rods 51 on the top 9 is set to about 25 m, and the first to third lifting rods 45 to 47 have a width of 2.
When the 5 m long slat material 2 is lifted, it comes into contact with both side edges of the slat material 2 to guide the upward movement of the slat material 2.

Each guide rod 51 consists of a large-diameter portion 51a that is thicker than the inner diameter of the mounting hole 50, and a shaft portion 51b that extends downward at a position offset from the center of the lower end surface, and the coaxial portion 51b is inserted into the mounting hole 50. has been done. From the mounting hole 50, the shaft portion 5
The lower end of 1b protrudes downward, and a retaining ring 53 is attached to the protruding portion. And the retaining ring 53
and the lower surface of the support member 48, 49.
A coil spring 54 is wound in a compressed state on the top, and urges each guide rod 51 downward.

As shown in FIG. 1.5, a bottle 55 is inserted and fixed to the lower end of the large diameter portion 51a of each guide rod 51. As shown in FIG. Both end portions of the bottle 55 protrude from the outer peripheral surface of the large diameter portion 51a, and both protruding portions form a positioning groove 55 extending in the front-rear direction at the upper end opening of the mounting hole 50.
It is removably engaged within a. These pins 55 and positioning grooves 50a constitute a stopping means.

Therefore, each guide rod 51 is lifted up against the biasing force of the coil spring 54 to remove the bottle 55 from the positioning groove 5Qa, and in this state, the guide rod 51 is rotated 180″' to again move the bottle 55 into the positioning groove 50a. When the guide rods 51 are engaged with each other, it is possible to change the distance between the pair of guide rods 51 on each support member 48, 49 to a predetermined value (approximately 35 mm in this embodiment).

As shown in FIG. 1.4, on the left side surface of the support member 48 and the right side surface of the support member 49, each recess 48a, 49
A pair of front and rear holding members 56 are rotatably supported by a shaft 57 at the lower position of a. Each holding member 56 is attached to the shaft 5
It consists of an extending part 56a extending forward or backward from the end of the extending part 56a, and an acting part 56b extending upward from the end of the extending part 56a.
It is formed to be wide so that it approaches b.

Further, the pair of front and rear holding members 56 are connected by a coil spring 58 as a biasing means at a position above the shaft 57, and biased toward each other. However, since a stopper 59 is integrally formed at the upper end of the acting portion 56b of each holding member 56, when this stopper 59 comes into contact with the guide rod 51, each holding member 56 is always in the state shown in FIG. In other words, the upper end portion of the action portion 56b is located in a state where it protrudes between both guide rods 51.

Therefore, when the slat material 2 is lifted by the first to third lifting rods 45 to 47 as the moving body 43 moves upward, each holding member 56 resists the biasing force of the coil spring 58.
It is pushed out by the slat material 2. Then, when the slat material 2 is lifted above the holding member 56, the holding member 56 returns to the position shown in FIG. Therefore, even if the first to third lifting rods 45 to 47 descend in this state, the slat material 2 will be placed on the holding member 56.

A metal support plate 60 protruding leftward is fixed to the lower part of the support member 48, and a slat guide member 62 is removably mounted on this support plate 60. That is, a pair of locking pins 65 are vertically inserted and fixed at the front and rear left ends of the slat guide member 62, and the upper and lower ends of each locking pin 65 protrude from both upper and lower surfaces of the slat guide member 62, respectively. ing. The slat guide member 62 is attached to the support plate 60 by engaging the ends of these locking pins 65 into locking holes 61 transparently provided at the front and rear left ends of the support plate 60. . In addition,
Magnets 66 are embedded in both the front and rear ends of the upper and lower surfaces of the slat guide member 62, and when the magnets 66 are attracted to the support plate 60, the locks inserted into the locking holes 61 are It is designed to prevent the pin 65 from coming out.

Above and below the slat guide member 62 are first and second guide grooves 63 and 64 for guiding the slat material 2 fed out by the supply roller 15 described above between the pair of front and rear guide bars 51 on the support member 48. is formed. The first guide groove 63 is formed to have a width of about 2511 mm at the right end,
On the left side, the throat is wider and deeper.

Therefore, when the slat material 2 passes through the first guide groove 63, it comes into contact with the inner wall 63a, thereby restricting swinging in the front-back direction.

Further, the second guide groove 64 is formed to have a width of approximately 35 mm at the right end, and is formed to be wider and deeper at the left end. Therefore, if the slat guide member 62 is removed from the support plate 60 in the state shown in FIGS. 1 and 7, and the slat guide member 62 is reversed and attached to the support plate 60 again, the slat material 2 with a width of 35 mm can be guided. It is possible to lead between the rods 51.

As shown in FIG. 6, a mounting plate 67 is fixed to the lower front end of the board 28, and a tension boob IJ68 for appropriately tensioning the ladder cord 6 is rotatably supported at the lower left end of the mounting plate 67. There is.

Further, a fixed roller 71 is provided at the lower right end of the mounting plate 67. The ladder cord 6 is guided between the second and third lifting rods 46 and 47 via a tension bar I768 and a fixed roller 71.

Incidentally, first and second guide pieces 73 and 74 in the form of thin plates as shown in FIG. 5.6 are attached to a link mechanism (not shown) disposed on the board 28. When the movable body 43 is stopped at the lowest position and the slat material 2 is fed into the insertion device 27, the first guide piece 73 is located between the slat material 2 and the second and third lifting rods 46,47. The slat material 2 enters into the ladder cord 6 and widens the distance between the warp yarns, thereby assisting the insertion of the slat material 2 into the ladder cord 6. When the insertion of the slat material 2 into the ladder cord 6 is completed, the first guide piece 73 moves to the position indicated by the two-dot chain line.

Note that the first guide piece 73 has both front and rear edges formed in an oblique shape so that the width of the right side is narrow.

Further, when the movable body 43 stops at the lowest position and the slat material 2 is fed into the insertion device 27, the second guide piece 74 is located on the path of the slat material 2 and together with the first guide piece 73. The vertical swinging of the slat material 2 is restricted. When the insertion of the slat material 2 into the ladder cord 6 is completed, the second guide piece 74 is retracted backward from the path of the slat material 2 as shown by the two-dot chain line.

Next, the operation and effect of this embodiment configured as described above will be explained.

The slat material 2 having a width of 25 flll curved by the forming roller 10 of the slat forming section 3 is moved by the guide roller 1
2 and passes between a guide roller 16 and a pressure roller 17. At this time, as shown in FIG. 3, both side edges of the slat material 2 are in contact with the inner wall 24a of the second guide groove 24 of the guide roller 16, and the center portion of the upper surface is in contact with the pressing roller 17.

Therefore, the slat material 2 is introduced between the supply rollers 15 without swinging in the front-back direction and the up-down direction.

When the slat material 2 is sent out by the supply roller 15,
This slat material 2 is introduced into each insertion device 27 sequentially from the left side. That is, the slat material 2 first passes through the first guide groove 63 of the slat guide member 62. At this time, since the left side of the first guide groove 63 has a large opening in the upper and lower and front and rear directions, the slat material 2 is inserted into the first guide groove 63.
will surely enter. The slat material 2 that has entered the first guide groove 63 in this manner is prevented from swinging in the front-back direction by the inner wall of the right end portion of the first guide groove 63.

The slat material 2 that has passed through the slat guide member 62 enters between the pair of front and rear guide rods 51 on the left support member 48 . At this time, the movable body 43 and the first to third lifting rods 45 to 47 stop at the lowest positions, and the first guide piece 73
enters into the ladder cord 6 and spreads the space between the warp yarns, and the second guide piece 74 is positioned above the path of the slat material 2. Then, in this state, the slat material 2 is inserted into the ladder cord 6 that has been spread out by the first inner straw piece 73, and then passes between the pair of front and rear guide rods 51 on the right support member 49.

When the slat material 2 passes through the full insertion device 27 as described above, the slat material 2 is cut by the cutting device 14, and the first guide piece 73 and the second guide piece 74 are cut by the operation of the link mechanism. Move to the position indicated by the two-dot chain line in Figure 5. When the movable body 43 rises based on the rotation of the cam body 30, the slat material 2 inserted into the ladder cord 6 is lifted by the first to third lifting rods 45 to 47. At this time, guide rods 51 are erected on both side edges of the slat material 2, and the interval between both guide rods 51 is set to about 25 mm, so the slat material 2 comes into contact with these guide rods 51. It will move upwards in this state.

When the slat material 2 is lifted by the first to third lifting rods 45 to 47, each holding member 56 is pushed apart against the biasing force of the coil spring 58. Then, when the slat material 2 is lifted above the holding member 56, the holding member 56
returns to the position shown in FIG. Therefore, when the first to third lifting rods 45 to 47 descend in this state, the slat material 2 is placed on the holding member 56.

When the first to third lifting rods 45 to 47 descend to the lowest position, another slat material 2 is fed into the insertion device 27, and after that slat material 2 is inserted into the ladder cord 6 in the same manner as described above. It is cut and laminated on the holding member 56. When a predetermined number of slat materials 2 are stacked on the holding member 56, the operation of the slat insertion portion 7 is stopped.

By the way, the slat material 2 with a width of 35 m was assembled using the above-mentioned assembly machine.
When assembling blinds from scratch, proceed as follows. First, the slat forming part 3 is replaced with another slat forming part (set with a slat material having a width of 3511 mm) disposed near the slat forming part 3. Further, the ladder cord 6 is removed from the insertion device 27, and the ladder cord 6 corresponding to the 35 crane slat material 2 is set. Then, by operating the handle 21 on the mounting plate 4a of the slat conveying section 4,
The inner wall 23a of the first guide groove 23 is a slat material 2 with a width of 35 mm.
The vertical and horizontal positions of the guide roller 16 are adjusted so that it comes into contact with both side edges of the guide roller 16.

In addition, the slat guide member 62 in each insertion bag M27
is removed from the support plate 60, the slat guide member 62 is reversed so that the second guide groove 64 is located on the upper side, and then attached to the support plate 60 again.

At this time, the locking pin 65 of the slat guide member 62
By simply inserting the slat guide member 62 into the locking hole 61 of the support plate 60, the slat guide member 62 can be reliably positioned. In particular, in this embodiment, the support plate 60 is formed of metal, and the slat guide member 62 is provided with the support plate 60.
Since the magnet 66 that can be attracted to the slat guide member 62 is attached, the locking pin 65 of the slat guide member 62 can be prevented from falling out of the locking hole 61 of the support plate 60.

Additionally, each guide bar 51 on the support member 48,49
by pulling it upward against the biasing force of the coil spring 54,
The pin 55 fixed to the guide rod 51 is
8. Remove from the positioning groove 50a on 49. Then, in this state, the guide rod 51 is rotated 180'', and the pin 55 is again engaged in the positioning groove 50a.In this embodiment, the support member 48. Since the guide rod 51 is inserted into the mounting hole 50 of 49, when the guide rod 51 is rotated, the opposing guide rod 51
The interval between the two changes. In addition, all guide rods 51 are 180 mm.
When rotated by .degree., the distance between the guide shafts 51 can be changed to approximately 35 degrees.

When each guide rod 51 is rotated as described above to increase the distance between the opposing guide rods 51, the guide rods 51
As the holding members 56 move, the stoppers 59 of the holding members 56 are pressed outward, and as a result, the distance between the opposing holding members 56 is automatically widened. In addition, when assembling a blind from the slat material 2 having a width of 25 m again, the slat forming part is replaced and the guide roller 16, slat guide member 62, and guide rod 51 are operated in the reverse procedure to the above.

As described above, according to the assembly machine of this embodiment, by changing the vertical position of the guide roller 16, the vertical position of the guide grooves 63 and 64 in the slat guide member 62, and the interval between both guide bars 51, the width of 251 m and It can also be used when assembling blinds with slats 2 of 35 mm, so unlike conventional ones, there is no need to prepare as many assembling machines for the width of the slats 2. Since all settings changing operations are simple, the time required for changing settings is short.

[Effects of the Invention] As detailed above, according to the blind assembly machine of the present invention, the interval between the pair of guide bars on each support member can be changed according to the width of the slat material, and a plurality of guide bars with different widths can be assembled. Even when assembling a blind using slat materials of various types, there is an effect that the upward movement of the slat materials can be reliably guided.

Also, when both guide bars are moved relative to each other, the holding member can be made to protrude between the two guide bars following the relative movement, and the slat material lifted by the lifting bar can be reliably held at a predetermined height. can do.

Furthermore, not only can the slat material be guided between the two guide bars, but also the width of the guide groove that abuts on both side edges of the slat material can be changed according to the width of the slat material. Even when assembling a blind using slat materials of different sizes, the same slat materials can be reliably guided between both guide bars.

According to the blind assembly machine of the present invention, one of the plurality of guide grooves having different widths and diameters in the guide roller
This has the effect that even when assembling a blind using slat materials of different widths, the slant materials can be reliably guided between the two supply rollers. .
