JP-A-2005-23602

According to Patent Document 1, a high-quality artificial turf and a manufacturing method thereof are introduced. However, there has been no apparatus for continuously and efficiently producing the artificial turf.
Then, this invention aims at providing the apparatus which manufactures the said artificial grass continuously and efficiently.

In order to achieve the above object, the present invention provides a mat having a plurality of pot portions arranged in a double row and a plurality of rows at a predetermined interval toward a turf planting position by a feed mechanism at intervals corresponding to the arrangement intervals of the pot portions. Mat conveying path for conveying,
Turf material supply means for supplying a long turf material bundle corresponding to each of a plurality of pot portions arranged in a direction orthogonal to the conveying direction of the mat,
A plurality of needle punching machines for driving a bifurcated needle into the pot portion, and a needle supply mechanism for sequentially supplying the bifurcated needles to each needle driving machine, and the turf planting position by the feeding mechanism of the mat conveyance path A lawn planting means for embedding the turf material bundle in the pot part that has been transported with the bifurcated needle in a long state and sequentially planting and fixing it in a folded state on the inner bottom part of the pot part,
Cutter means is provided that is installed downstream of the grass planting position in the mat conveying direction and cuts the grass material bundle between pot portions adjacent to the mat conveying direction.

Further, the turf planting operation by the turf planting means and the cutting operation of the turf material bundle by the cutter means are performed during the mat feeding operation of the mat conveyance path.
According to the above configuration, the turf planting means descends toward the pot portion at the turf planting position, and the turf material bundle is pressed halfway in the longitudinal direction at the tip of the needle punching machine, and then folded in half. The needle punching machine operates to push the folds of the turf material bundle into the pot part while holding the folded part with a needle, and to plant and fix it on the inner bottom part of the pot part. When the turf material bundle is planted and fixed on the inner bottom of the pot portion, the turf planting means rises and returns, and the mat is fed by one feeding portion of the mat conveyance path. Thereby, the next pot part is sent to a turf planting position. In this case, the grass material bundle previously fixed to the inner bottom of the pot part goes out above the previous pot part with the two-fold part as a boundary and extends in two front and rear directions to extend the upper surface of the opening of the next pot part. It extends across the back. Here, the grass planting means descends again and the turf material is pressed halfway in the longitudinal direction at the tip of the needle punching machine, and then the needle driving machine operates to fold the folded part of the grass material bundle. While being held in with a needle, it is pushed into the pot part and planted and fixed to the inner bottom part of the pot part. Thereafter, this is repeated, and the grass material bundle is sequentially planted and fixed in the mat pot direction in a state of being continuous in the mat conveying direction. The cutter means cuts the grass material bundle planted and fixed in a state continuous to the pot portions arranged in the mat conveying direction on the downstream side of the turf planting position in the middle of the pot portions adjacent to each other in the mat conveying direction. Then, separate stocks are formed for each pot part. The turf material bundle cut by the cutter means is radially expanded around the upper part of each pot portion, and becomes a leaf-like piece of natural turf. That is, the portion pushed into the pot part becomes a stem-like root part, and this stem-like root part is planted and fixed to the inner bottom part of the pot part with a bifurcated needle in a state where the grass material bundle is folded in two, so that the root part is potted It is firmly planted and fixed by the needle so as not to come out of the part. Thus, according to the above configuration of the present invention, there is obtained an apparatus for continuously and efficiently producing artificial turf that has many leaf-like pieces extending upward from each pot part and imitates natural turf. It is done.

The plurality of needle driving machines of the turf planting means are arranged such that one pot portion is arranged in the orthogonal direction with respect to a pot portion in a direction orthogonal to the mat conveying direction of the plurality of pot portions arranged in a double row and a double row on the mat. The stitching operation is performed twice with respect to a single feeding operation of the mat, and at this time, only the interval between the adjacent pot portions in the first operation and the second operation is described above. The needle driving machine and the mat are relatively traversed in the orthogonal direction.
According to the above configuration, even when the adjacent arrangement interval of the pot portions is equal to or smaller than the width of each needle punching machine, the plurality of needle punching machines are arranged at intervals that do not hinder the needle driving operation without overlapping adjacent needle driving machines. It is possible to manufacture a high-quality artificial turf with a high density of turf material bundles.

Further, a hook member installed at an upper portion between the pot portion before the turf planting position at the turf planting position and the pot portion after the turf planting position one downstream from the pot portion in the mat conveying direction. And, during the turf planting operation of the turf planting means, prior to the operation, the turf material bundle between the pot parts is lifted and held at a predetermined height position between the pot parts by the hook member, The turf planting length setting means comprising a hook member drive mechanism for releasing the lifting and holding of the turf material bundle after the turf planting means has been planted is provided.
According to the said structure, the planting length of the grass material bundle planted in each pot part, especially the length of the leaf-like piece extended to the upper part from a pot part can be set suitably.

In addition, a concave portion for positioning the turf material bundle on the pot portion is formed upward at the tip of the needle driving machine of the turf planting means.
According to the above configuration, the grass material bundle immediately before being pushed into the pot portion with the bifurcated needle is positioned and held at a fixed position (substantially central position) on the pot portion by the concave portion of the tip portion of the needle punching machine. Thus, the grass material bundle can be securely held in the pot portion with a bifurcated needle and can be reliably planted and fixed to the bottom portion of the pot portion.
The cutter means is characterized in that it can reciprocate and move from one end of the mat in the direction perpendicular to the mat conveying direction to the other end.

According to the above configuration, a plurality of rows of turf material bundles planted in a plurality of pot portions in a direction orthogonal to the mat conveying direction are sequentially cut from one end to the other end in the mat conveying direction by one cutter means. The configuration of the cutter means can be simplified.
Further, the cutter means comprises a rotary blade type cutter and a fixed inclined blade type cutter inclined forward and downward in the running direction, and the former is installed on the upstream side in the mat conveying direction and the latter is installed on the downstream side. It is a feature.
According to the above configuration, the turf material bundle between the pot portions is cut by the rotary blade type cutter installed on the upstream side in the mat conveying direction, and the uncut material is installed on the downstream side in the mat conveying direction. It can be cut by a fixed inclined blade type cutter, and the turf material bundle can be cut reliably at high speed. That is, according to the fixed inclined blade type cutter, since the grass material bundle loops up and passes from below, it can be cut reliably, but the entire grass material bundle is to be cut. Then, since it is necessary to cut at a time with the inclined blade surface that moves in a transverse direction, the cutting resistance is large, and it becomes difficult to cut at a high transverse speed. On the other hand, according to the rotary blade type cutter, the entire turf material bundle can be cut little by little by the blade surface rotating at a higher speed than the traversing speed, so the cutting resistance is reduced and the traversing speed is increased. Although it is possible to cut the turf material, a part of the turf material bundle may be left uncut. Therefore, by arranging the rotary blade type cutter on the upstream side and the fixed inclined blade type cutter on the downstream side, the entire turf material bundle is cut first with the rotary blade type cutter, By cutting with a fixed inclined blade type cutter, the turf material bundle can be surely cut at high speed by utilizing both advantages.

This is used to accommodate the grounding as the leg 6a so as not to interfere.

  As shown in FIG. 1 and FIG. 6, the turf material supply means 2 is configured to lay a long turf material bundle 10 obtained by bundling a predetermined number of a plurality of resin narrow strings in a rope shape perpendicular to the conveying direction of the mat 7. It comprises a fixed guide 2a and a movable guide 2b that are supplied in correspondence with each other on a plurality of pot portions 6 arranged in the direction of the movement. The narrow string constituting the turf material bundle 10 is formed as thin as a real turf leaf shape as a flat or circular cross section by a resin having abundant flexibility and elasticity (shape restoration property). Each string is attached with a coiled twister or is kept straight, and the number of bundles is also set appropriately. The turf material bundle 10 is wound around a bobbin or a reel, and is replaced and replaced with a holding base (not shown) installed on the upper side of the mat conveyance path 1 in the conveyance direction start side (right side in FIG. 1). It is installed so that it can be replenished, and is pulled out from this portion and mounted on the fixed guide 2a and the movable guide 2b. The starting end of the grass material bundle 10 is planted in the pot portion 6 of the mat 7 by manually operating a grass planting means 3 described later, and thereafter the mat 7 is moved in the transport direction by the feed mechanism 8 of the mat transport path 1. It is fed out sequentially by being fed intermittently, and does not have a dedicated feeding means, and is equipped with means (not shown) for keeping the feeding tension of the grass material bundle 10 constant, thereby preventing slack in the middle. It is set as the structure. A plurality of the fixed guides 2a are arranged on the support bar 1d on the upstream side of the turf planting position 9 on the mat conveyance path 1 in correspondence with the arrangement interval of the pot portions 6 (the arrangement interval in the direction orthogonal to the conveyance direction). Has been. As shown in FIGS. 3 and 6, the movable guide 2 b is composed of a single bar, and guide recesses 2 c are formed at positions corresponding to the arrangement intervals of the pot portions 6. The movable guide 2b is installed so as to be able to move up and down together with a lawn planting means 3 described later above a position immediately before the lawn planting position 9.

  As shown in FIGS. 1 and 6 to 8, the turf planting means 3 includes a plurality of needle punching machines 12 for driving a needle 11 having a bifurcated tip into the pot portion 6, and a bifurcated shape on each needle hammering machine 12. A needle supply mechanism 13 for sequentially supplying the needles 11 is provided, and the turf material bundle 10 is kept long in the pot portion 6 that has been conveyed to the turf planting position 9 by the feed mechanism 8 of the mat conveyance path 1. It is configured such that it is held between the tips of the bifurcated needle 11 and pushed into the pot portion 6 in a folded state and is sequentially implanted and fixed to the inner bottom portion of the pot portion 6 (see FIGS. 16 to 19). . The turf planting means 3 is installed above the turf planting position 9 in the mat conveyance path 1 so as to be capable of moving up and down and traversing.

  In order to raise and lower the turf planting means 3, as shown in FIGS. 3 and 4, two guide columns 14 and 14 are erected from the machine base 1 e on both sides of the mat conveyance path 1. A first elevating block 15 is guided and supported by the guide struts 14 and 14 so as to be movable up and down. A guide rail 16 is attached to the lower surface of the first elevating block 15, and slide members 17 and 17 are attached to the guide rail 16. The mounting head 18 is guided and supported so as to be capable of traversing. A plurality of needle punching machines 12 are attached to the attachment head 18 at predetermined intervals in a direction orthogonal to the mat conveying direction. As shown in FIG. 3, the upper portions of the two guide columns 14 and 14 are connected by a flange 19 straddling the mat conveyance path 1, and a first elevating drive body 20 is installed on the flange 19. The first lifting block 15 is moved up and down by the first lifting drive body 20. Further, as shown in FIG. 4, a first traversing drive body 21 is attached to the rear surface side of the first elevating block 15, and the mounting head 18 is attached to the first elevating block 15 by the first traversing drive body 21. On the other hand, a traversing operation is possible in a direction orthogonal to the mat conveying direction. A bracket 18a is attached to the mounting head 18, and this bracket 18a is connected to a movable part of the first traversing drive body 21, thereby enabling the operation. The first elevating drive body 20 and the first traversing drive body 21 are composed of a fluid pressure cylinder device such as air pressure or hydraulic pressure, an electromagnetic solenoid device, or the like, and the operation amount can be adjusted by adjusting the position of the stopper or the like. Has been.

  As shown in FIG. 7, the needle punching machine 12 includes a guide member 12b that forms a guide path 12a for passing only one bifurcated needle 11 with its needle point downward, and the guide member 12b A hammer 12c that strikes and strikes the back of the needle 11 along the guide path 12a and a launching drive body 12d that imparts a striking force to the hammer 12c are provided. The power source of the launching drive body 12d includes For example, an air compressor that generates a pressure-adjustable air pressure is used. The hammer 12c is configured to strike the needle 11 with a predetermined air pressure supplied to the firing drive body 12d and to return the hammer 11 after the launch by a spring (not shown).

  Further, the hammer 12c is configured to protrude long from the tip end portion of the guide member 12b of the needle driving machine 12 until it reaches the bottom portion 6d of the pot portion 6. That is, the protrusion length of the hammer 12c is generally configured to protrude only slightly from the tip of the guide member 12b. The reason for this is that in this type of needle punching machine 12, the tip of the guide member 12b is usually brought into contact with the surface of the object to be driven by the needle 11 to apply a striking force to the hammer 12c. The tip is pushed out from the tip, the tip is penetrated and protrudes through the back surface of the object to be bound, and the object to be driven is bound, and the protrusion length of the hammer 12c from the tip of the guide member 12b at that time is the surface of the object to be driven. It is sufficient to push the button slightly, and it is not necessary to make it longer, and it is harmful. However, since the guide groove 6f, 6f is deeply formed in the pot portion 6 which is a driving object of the present invention from the upper surface of the pot portion 6 to the bottom portion 6d, the protrusion of the hammer 12c from the tip of the guide member 12b. If the length is short and slightly as in the conventional general configuration, the needle 11 cannot be reliably driven to the bottom 6d of the pot portion 6 and the driving is insufficient. Therefore, in the present invention, the protruding length of the hammer 12 c from the tip of the guide member 12 b is set to be as long as the depth of the pot portion 6.

  As shown in FIG. 7 and FIG. 9, concave portions 12 e for positioning the turf material bundle 10 on the pot portion 6 are formed in the upward direction on both sides of the mat conveying direction at the tip of the guide member 12 b of the needle punching machine 12. ing. According to this configuration, the grass material bundle 10 immediately before being pushed into the pot portion 6 by the bifurcated needle 11 is placed at a fixed position (substantially central position) on the pot portion 6 by the concave portion 12e at the tip of the needle driving machine 12. Thus, the grass material bundle 10 can be securely held in the pot portion 6 by the bifurcated needle 11 and can be securely planted and fixed to the bottom of the pot portion 6. . Since the pot portion 6 is provided with guide grooves 6f and 6f, the guide grooves 6f and 6f allow the tip of the hammer 12c and the tip of the bifurcated needle 11 to smoothly move without shifting until reaching the bottom 6d of the pot portion 6. Guided.

  Corresponding to the needle punching machine 12, a cradle 22 fitted in the raised bottom space 6e to support the bottom part 6d of the pot part 6 on the lower surface side of the mat 7 at the turf planting position 9 is a lifting mechanism 23 shown in FIG. It is installed so that it can be moved up and down. As shown in FIGS. 1 and 3, a plurality of cradles 22 are arranged in a one-to-one correspondence with the pot portions 6 for one row arranged in a direction orthogonal to the mat conveying direction. As shown in FIG. 16, a bending guide surface 22 a that bends the needle tip of the bifurcated needle 11 inward is formed on the upper surface of each cradle 22. As shown in FIG. 5, the elevating mechanism 23 of the cradle 22 includes a driving body 23a such as an air cylinder, a toggle link 23b that is bent and stretched by the driving body 23a, and an elevating member 23c connected to the toggle link 23b. The cradle 22 is attached to the elevating member 23c. The driving body 23a is supported by the fixed bracket 23d, and the tip of the movable member 23a1 is pin-connected to the intermediate point of the toggle link 23b. The toggle link 23b is connected to the upper end of the lower link 23b1 whose lower end is pin-connected to the fixed bracket 23e and the lower end of the upper link 23d2 whose upper end is pin-connected to the elevating member 23c to the front end of the movable member 23a1 of the driving body 23a. Thus, the upper and lower links 23b1 and 23b2 have the same length. The raising / lowering member 23c is supported by a part of the machine base 1e so that raising / lowering is possible.

  The lifting mechanism 23 of the cradle 22 moves up prior to the needle punching operation of the needle punching machine 12 and fits into the raised bottom space 6e to support the bottom 6d of the pot 6 at the turf planting position 9. Then, while receiving the needle tip of the bifurcated needle 11 which is driven through the bottom portion 6d into the pot portion 6 by the hammer 12c of the needle punching machine 12 with the bent guide surface 22a on the upper surface of the pedestal 22, the inner side. As shown in FIGS. 7 and 17, the turf material bundle 10 that has been clamped into the bottom surface of the bottom portion 6d in the pot portion 6 and fixed into the pot portion 6 and pushed into the pot portion 6 in a folded state by the needle 11 is bent. It is securely planted and fixed to the inner bottom portion 6d of the pot portion 6.

  In addition, as shown in FIGS. 7 and 8, the needle supply mechanism 13 includes an assembly in which a bifurcated needle 11 with a needle tip portion facing downward is bonded and connected in a predetermined unit number (for example, 50). The holder 13a has a rail-like holder 13a that is placed and supported with the needle tip portion facing downward, and an extrusion claw 13b. The extrusion claw 13b has a substantially U-shape similar to that of the needle 11, and the holder 13a The needle 11 placed over and supported by the holder 13a by a spring 13c stretched in the holder 13a is pushed out toward the guide path 12a of the guide member 12b of the needle punching machine 12. It is configured. As shown in FIG. 6, the needle supply mechanism 13 is attached to the rear surface side of the guide member 12 b of the needle punching machine 12, and is moved up and down integrally with the needle driving machine 12. The push-out direction of the needle 11 supported by the holder 13a by the push-out claw 13b is a direction orthogonal to the hammering direction of the hammer 12c. For this reason, the holder 13a extends rearward from the rear surface of the guide member 12b. It is attached to the guide member 12b. The aggregate of the needles 11 is such that only the leading needle 11 protrudes from the tip of the holder 13a into the guide path 12a of the guide member 12b, and the subsequent needle 11 is not inserted into the guide path 12a but is held by the holder 13a. Therefore, when the hammer 12c is driven out, only the leading needle 11 is driven out, and when the hammer 12c returns, the next needle 11 becomes the leading and is pushed into the guide path 12a. Thus, the aggregate of the needles 11 supported by the holder 13a of the needle supply mechanism 13 is driven out so as to be sequentially cut out from the top one by the hammer 12c.

  The raising / lowering operation amount by the first raising / lowering driving body 20 of the turf planting means 3 is set as appropriate, but the lower end position is such that the tip of the guide member 12b of the needle punching machine 12 is located on the pot portion 6 of the mat 7. It is set to a position in contact with the upper surface of the opening. In addition, the operating condition is set so that the traversing operation of the first traversing drive body 21 is performed only when the needle driving machine 12 is at the ascending end position. This is a distance corresponding to the arrangement interval of the pot parts 6 arranged in the direction orthogonal to the mat conveying direction among the pot parts 6 arranged in a double row. Correspondingly, the mounting interval of the needle driving machine 12 mounted on the mounting head 18 is arranged in a direction orthogonal to the mat conveying direction among the pot portions 6 arranged in a double row and a double row on the mat 7. The interval is equivalent to twice the arrangement interval of the pot portions 6. That is, the attachment interval of the needle punching machine 12 is continuously provided at every other interval of the pot portions 6 in the direction orthogonal to the mat conveying direction. With this configuration, the pot 7 arranged in the direction orthogonal to the mat conveyance direction is made to perform the needle driving operation by the needle driving machine 12 twice with respect to the single feeding operation of the mat 7. The needle 11 is driven into the odd-numbered portion of the portion 6, and in the second operation, the needle driving machine 12 is caused to traverse by one portion of the pot portion 6 through the mounting head 18 by the first traversing drive body 21. Later, the needle 11 is driven by the needle driving machine 12, whereby the needle 11 is driven into the even-numbered pot portion 6 in the second operation. If comprised in this way, even when the arrangement | positioning space | interval of the pot part 6 formed in the mat 7 is below the width dimension of the needle punching machine 12, it can arrange | position so that adjacent needle driving machines 12 may not overlap.

  As shown in FIGS. 7 and 10, the turf planting length setting means 4 includes a pot unit 6 before turf planting at the turf planting position 9 and one pot downstream from the pot unit 6 in the mat conveying direction.
