Description

  The present invention relates to a collection device for a cigarette butt and the like that is disposed in an island facility where a gaming machine such as a pachinko is installed and collects garbage such as cigarette butt and paper waste thrown by a player.

  Game machines such as pachinko machines that play games using game balls and revolving game machines that play games using game balls or medals (so-called parrots, slot machines) have housings in preparation for smoking by players. A cigarette holder is provided separately. Conventionally, in many amusement halls, it has been common for an attendant to periodically circulate and collect butts before the butts are full. However, in recent years, a recovery device has been installed inside the island facility where game machines are arranged in order to immediately recover the generated butts without interrupting the game of the player, to reduce the work burden of the staff. There are an increasing number of amusement halls that use a system in which a cigarette butt is inserted into an inlet formed in an island facility and automatically collected instead of a cigarette jar in a gaming machine housing. In such a collecting apparatus, in addition to cigarette butts, garbage such as paper scraps discarded by the player can be transferred and collected through the slot.

  As this type of recovery device, for example, in Patent Document 1 below, a screw member connected along the longitudinal direction of an island facility where a gaming machine is installed, and a long hollow that accommodates the screw member and serves as a recovery path for the butts A device for butt collection device comprising a member is described. Patent Document 2 below proposes a recovery device that can bend the suction path of the cigarette butt. In this device, a plurality of screw shafts having a spiral blade body are connected to each other by a universal joint in a state where the screw shafts are bent to each other, so that a driving force from a driving source provided at one end is effectively obtained. It can be transmitted to the other end. As a result, it is possible to automatically collect butts even in an island facility in which a gaming machine is arranged in a bent shape to improve layout.

  In recent amusement halls, the number of game machines installed in parallel on the island facilities varies from store to store in order to effectively use the store space and diversify the layout. In addition to the side-by-side pattern, attempts have been made to bend the whole into a U-shape, curve it into an arc shape, or combine them. On the other hand, a problem arises when the cigarette collection device described in each of the above patent documents is mounted on an island facility.

  In the case of the cigarette collection device described in the above-mentioned Patent Document 1, the screw member divided into a plurality of parts is connected linearly to constitute the means for transferring the cigarette butt, so that the gaming machine can be changed by changing the number of connections. Although it can follow changes in the number of installed units, it cannot cope with bent or curved island facilities (see Patent Document 1: FIG. 2).

  On the other hand, the screw shaft described in Patent Document 2 has been transferred along one screw shaft by shifting the phase of the blade body by 180 degrees and discontinuous at the connecting end portion connected by the universal joint. The cigarette butt is once pushed out into the inner space of the bent portion of the conduit, and this is scooped up by the blades of other screw shafts to bend the course of the butt. By using such a screw shaft as a means for transferring the butts, it is possible to cope with island facilities such as a bent shape or an arc shape in which gaming machines are bent and arranged with respect to each other.

  However, in such a system, since the transfer force for conveying the cigarette butt is temporarily interrupted at the bent portion, the butt tends to stay in the inner space of the bent portion, particularly outside the bend. This is because a dead space that does not touch either of the blades is generated outside the bend (see Patent Document 1: FIG. 4). The butts that stay in the dead space of the bent part continue to stay in that place until they are pushed out by the other butts that have been transported from the rear. There is a problem that off-flavors, smoke, harmful gases, etc. are generated. In addition, any butts that have been sent in sequence will always stay at the staying part of the bent part, so if this continues to burn, the part of the conduit will be overheated, and the player will enter the conduit from the outside. There is a risk of feeling heat when touching.

  In addition, when the inventions described in Patent Documents 1 and 2 above are combined, that is, a plurality of screw members whose blade members are adjacent to each other as in Patent Document 1, are bent and connected by a universal joint as in Patent Document 2. Also, on the outer side of the bent portion of the connecting portion, a gap is generated between the blade portions, and the butts are missed, resulting in the same problem as described above.

  The present invention has been made to solve the above-described problems, and can transfer dust such as cigarette butt and paper waste without stagnation, flexibly corresponding to the length of the island facility, linear shape, bent shape, curved shape, etc. It is an object of the present invention to provide a collection device such as a cigarette butt that can quickly collect this. Other objects of the present invention will become apparent from the following description.

  The present invention is characterized in that the pressing surfaces of the two screw bodies whose shaft ends are connected to each other by the shaft joint overlap each other at the connecting portion. As a result, such as cigarettes and paper scraps transferred to the tip of the screw body along the axial direction by the pushing surface of the screw body or along the axial direction and rotating around the axis by the helical pushing surface. It is possible to continue the transfer of the dust in the other axial direction by the pressing surface of the other screw body without interrupting the transfer force.

  In other words, dust such as a cigarette put into the conduit from the inlet is brought into contact with the inner surface of the conduit and a pushing surface formed in a spiral shape around the shaft portion, thereby causing a transfer force in the axial direction of the shaft portion. Receive. When transferring garbage in the intended transfer direction, the screw body is rotated in the direction opposite to the twisting direction of the spiral that proceeds in the transfer direction. In order to rotate the screw body, torque may be applied to the shaft portion by a rotation drive device such as a motor. Specifically, for example, when the push surface is formed as a right-handed spiral around the shaft (a spiral that rotates counterclockwise when viewed from the transfer direction), the shaft is rotated clockwise when viewed from the transfer direction. By rotating, the dust is transferred in the axial direction of the screw body by a drag force acting in the normal direction of the pressing surface that comes into contact. In addition, due to the dynamic frictional force between the dust and the pushing surface, a part of the load also acts on the dust in the direction of rotation of the pushing surface, but the dust remains in the axial direction of the screw body while falling to the bottom of the conduit due to its own weight. It is transferred to. In addition, since the push face of the other screw body (transfer destination) having the same spiral direction overlaps and continues to the tip of the push face of one screw body (transfer source), the tip of the one screw body (transfer source) As described above, the dust that has been transferred to the end is continuously transferred from the base end (rear end) to the front end by the pressing surface of the other screw body.

  In addition, by making the shaft joint that connects the two screw bodies into a universal joint, this screw body can be connected to the "U" shape with a predetermined bending angle, not to mention that these screw bodies are aligned in a straight line. Even in such a case, the torques of the rotary drive devices can be transmitted to each other. Therefore, even in an island facility where gaming machines are arranged side by side rather than in a straight line, a set of collection devices such as butts according to the present invention is provided from each of the inlets provided corresponding to the planned installation positions of the gaming machines. Can collect garbage. In addition, by increasing the number of screw bodies to three or more and connecting them in series with two or more universal joints, the game machine is placed on a curved island facility, exceeding the “U” shape. Even if it is a case where it arrange | positions to the perimeter along the periphery of island equipment, the collection apparatus, such as a cigarette which collects garbage from the installation position of each game machine, is realizable.

  FIG. 1 is a front view of an island facility 100 provided with a collection device 10 such as a cigarette butt according to an embodiment of the present invention. FIG. 2 shows a gaming machine 102 installed in the island facility 100 (not shown in the figure) and each game. It is a perspective view of the replenishment basket 120 which replenishes a game ball to a machine. Examples of the gaming machine 102 include a pachinko machine, a parrot, a slot machine, and an arrange ball. The gaming machines 102 are installed in the island facility 100 in two rows side by side with their backs (hatched in FIG. 2) facing each other. As a side-by-side mode, in addition to the conventional straight line island, which is the most common in the past, adjacent game machines 102 have a predetermined bending angle as shown in the figure, and at least a part of the longitudinal direction of the island equipment 100 and the supply rod 120 Can be in the form of a so-called R island with a polygonal shape or a curved shape. In addition, a game medium supply device such as a ball lending machine that supplies a player with a game medium such as a pachinko ball may be installed between the game machines 102.

  Generally, in the island facility 100, a board 121 for placing a game medium storage box (commonly called a dollar box) in which a player stores game media such as a game ball and a medal is placed on the waist and chest of the player who is playing the game. It is formed so as to protrude toward the player at the height position. The board 121 also functions to place and support the gaming machine 102 attached to the island facility 100. The saddle plate 121 is supported and fixed to the bottom plate of the island facility 100 and the floor of the amusement shop by a waist plate 122 standing below. In addition, the island facility 100 includes a recovery device 123 that recovers the game media discharged from the gaming machine 102, a lifting device 124 that transfers the recovered game media to the supply tank 125, and the like.

In addition, in the island facility 100 in which the collection device 10 for sucking butt according to the present invention is used, an insertion port 104 is formed in the base plate 121 so as to correspond to the installation position of the gaming machine 102, so It is possible to drop trash such as paper scraps (hereinafter referred to as “butt butts”) into it and throw it away. An ashtray is formed at the input port 104 so as to surround it, and the lit cigarette can be temporarily placed or the cigarette can be extinguished.
The butterfly collection device 10 that transfers and collects the dropped butts etc. is generally provided on the back surface of the board 121 and far from the player, that is, on the front side of the waist plate 122. This is because the input port 104 is provided in a range where the player does not hit his / her feet or the like on the collection device 10 such as the cigarette but can be easily reached by the player's hand (generally the left hand) during the game. . In the R island, in order to make the relative positional relationship between the gaming machines 102 and the insertion slot 104 aligned in the longitudinal direction constant, the insertion slot 104 has an arc shape corresponding to the planned installation position of the gaming machine 102. It is good to provide in a distributed manner.

  Therefore, when the collection device 10 for sucking butt or the like according to the present invention is used on the R island, the conduit 20 has a curved shape or a bent shape that sequentially connects the charging ports 104 so that the sucking shells and the like charged from any of the charging ports 104 can be collected. Formed and communicated with each of the inlets 104.

  The recovery device 10 for a cigarette butt according to the present invention includes a screw body in which a spiral push surface is formed around a shaft portion as a transfer means such as a cigarette butt. A state in which the butt or the like is transferred by the screw device 30 provided in the inside of the conduit 20 composed of a half-cylindrical cylindrical member will be described with reference to the schematic longitudinal sectional view of FIG.

The screw device 30 includes a shaft portion 31 that extends in the transfer direction (leftward in the figure) of the cigarette shell 110 and the like, and a blade portion 34 that protrudes in the radial direction. The pushing surface 36 corresponding to the entire blade portion 34 or at least the front surface side (the left side of the figure) that contacts and at least contacts the butterfly shell 110 is formed in a spiral shape. The push surface 36 illustrated in the figure has a right-handed spiral shape.
A highly rigid shaft 70 made of metal or the like is coaxially fixed to the shaft portion 31, and the blade portion 34 rotates around the shaft portion 31 by applying torque to the shaft 70 by a rotary drive device 50 such as a motor. In the present embodiment, the shaft 70 is inserted into the shaft portion 31 formed in a hollow cylindrical shape, and both are fixed by pins, screws, adhesives, or the like. By adopting such a method, the torque applied from the rotary drive device 50 is transmitted exclusively in the longitudinal direction of the collection device 10 such as the sucking butt through the shaft 70, so that it is not necessary to increase the torsional rigidity and strength of the screw device 30. There is an advantage. However, when the torsional rigidity and strength of the shaft portion 31 are sufficiently high, the shaft 70 may be connected to the end portion of the shaft portion 31.

The rotation driving device 50 is fixed to the flange plate 121 by a bracket 51. Further, by making the joint 52 that transmits the torque of the rotation drive device 50 to the shaft 70 a universal joint, even when the rotation drive device 50 swings around the rotation shaft 53, the vibration in the direction orthogonal to the rotation shaft 53 is shaken. Is prevented from being transmitted to the shaft 70 or the screw device 30.
In addition, although the figure has shown the aspect by which the rotational drive apparatus 50 is arrange | positioned ahead in the transfer direction, in this invention, you may arrange | position the rotational drive apparatus 50 to the transfer origin side, and also the both sides of the screw apparatus 30 Alternatively, it may be arranged at an intermediate position in the longitudinal direction.

The cigarette shell 110 or the like is transferred in the axial direction of the screw device 30 in response to a drag force acting in the normal direction of the pressing surface 36 that abuts. By making the clearance between the conduit 20 and the end of the push surface 36 relative to the outer diameter of the butt 110 or the like, that is, the distance (d0) between the bottom of the inner surface of the conduit 20 and the peripheral end of the push surface 36, The butt 110 or the like 110 is given a transfer force without spilling from the push surface 36. In other words, the spiral diameter of the pushing surface 36 formed to protrude from the surface of the shaft portion 31 of the screw body 301 accommodated in the conduit 20 is determined according to the diameter of the inner surface of the conduit 20. That is, the maximum radius of the spiral is equal to the radius of the inner surface of the conduit 20, and the minimum radius is the radius of the inner surface of the conduit 20 minus the diameter of the cigarette 110 or the like to be transferred. In addition, about the inner surface upper part of the conduit | pipe 20, the space | interval to the peripheral edge part of the pressing surface 36 may exceed the said d0. This is because even if the butts or the like lifted up by the screw body 301 leak from the pushing surface 36 at the upper part of the inner surface of the conduit 20, the butts and the like reach the bottom of the conduit 20 again by their own weight, and the transfer force by the pushing surface 36 continues. Because it will receive.
Here, in the case where a leftward transfer force (CF) is applied to the butt or the like 110 in the figure, the shaft portion 31 can be rotated in a direction opposite to the spiral direction of the push surface 36 as seen from the transfer direction as described above. Therefore, the direction of the torque (TR) applied to the shaft 70 is clockwise as seen from the transfer direction as shown in the figure. When the direction of the spiral of the push surface 36 is opposite, or when the transfer direction of the cigarette butt 110 is reversed, the direction of the torque (TR) may be reversed.

  FIG. 4 is a perspective view of the screw device 30 according to the embodiment of the present invention. The direction of transfer of the cigarettes is indicated by arrows in the figure. The screw device 30 is configured by connecting a screw body 301 positioned ahead in the transfer direction and a screw body 302 positioned rearward by a shaft joint such as a universal joint 40. When the number of screw bodies to be connected is three or more, the number of connecting portions by the shaft coupling is two or more. The shaft coupling transmits torque applied to one screw body to the other screw body to be connected. In particular, as in the present embodiment shown in the figure, when the screw bodies 301 and 302 to be connected form a predetermined bending angle, the universal joint 40 is used as the shaft joint so that the screw bodies 301 and 302 can be connected to each other. Torque can be transmitted, and the transfer direction of the butts can be bent.

  In the screw device 30 according to the present invention, the screw bodies 301 and 302 constituting the screw device 30 may be connected in a straight line by a flange joint or a sleeve joint, or may be bent and connected by the universal joint 40. The pushing surfaces 36a, 36b are overlapped (overlapped) with each other at the shaft ends 32a, 32b to be connected. Thereby, regardless of whether the entire screw device 30 has a linear shape or a bent shape, it is possible to apply a continuous transfer force to the butts and the like. That is, unlike the above-described conventional butt collection device, the butt or the like continues to receive a transfer force even at the bent portion, and therefore does not spill from the push surface 36 of the screw device 30.

  Therefore, in the present invention, as long as the pressing surfaces overlap each other at the connection end of the screw body connected by the shaft coupling, the transfer force such as the sucking cup is not divided in the middle, and the individual screw bodies are separated. There is no limit to the length or number of connections. The lengths of the individual screw bodies can be determined according to the bent shape of the island facility 100 and the arrangement interval of the inlets 104, and can be adjusted to the width dimensions of the gaming machine 102 and the game medium supply device arranged side by side, for example. it can.

  The screw bodies 301 and 302 may have portions where the pressing surfaces 36a and 36b overlap at an intermediate portion other than the connecting end portion by the shaft coupling. Specifically, each of the screw bodies 301 and 302 according to the present embodiment is configured by further connecting a plurality of screw parts 60 coaxially and in series as shown in FIG. As a mode of connection, a method of attaching a plurality of screw components 60 to the shaft 70 may be used in addition to providing an uneven fitting portion described later on the shaft portion 31 of the screw component 60. In this way, the screw device 30 is configured by connecting a plurality of screw bodies 301, 302 linearly or bent by a shaft coupling, and the screw bodies 301, 302 are configured by connecting a plurality of screw parts 60 to each other. It is composed.

  In the present invention, as shown in FIG. 4, a shaft coupling 31 such as a universal joint 40 is attached to the shaft portions 31a and 31b of the screw bodies 301 and 302, and the screw parts are coupled as shown in FIG. The shaft part 31 of 60 itself constitutes a part of a shaft joint (joint parts 401 and 402 to be described later), and the screw parts 60 are pin-coupled. That is, the shaft coupling may be prepared as a separate member from the screw bodies 301 and 302 and the screw component 60 constituting the screw bodies 301 and 302, or the shaft coupling may constitute a part of them.

FIG. 5 is a perspective view of the screw component 60. 6A is a left side view of the universal joint 40, FIG. 6B is a front view thereof, and a DD sectional view thereof is shown in FIG. FIG. 3C is a right side view of the universal joint 40.
As shown in the figure, the screw component 60 includes a shaft portion 31 and a blade portion 34 having a spiral pushing surface 36 formed so as to protrude from the peripheral surface thereof. The blade portion 34 extends in the axial direction from the shaft end 32 of the shaft portion 31 and is provided with an extending portion 38. In the present invention, the extending portion 38 may be formed only on either the front or rear in the axial direction.

  Therefore, by connecting the shaft ends 32 of the two screw parts 60 so that the spiral directions of the push faces 36 coincide with each other, the push face 36 in the extending portion 38 is connected to the push faces of the other screw parts 60 to be joined. It overlaps with a predetermined length. In particular, when the extending portions are provided so as to protrude from both ends of the shaft portion 31, the extending portions 38a and 38b overlap each other as shown in FIGS. Such an overlap is not only a connecting portion between the screw bodies 301 and 302 connected by a shaft joint such as the universal joint 40, but also a screw part constituting each of the intermediate portions in the longitudinal direction of the screw bodies 301 and 302. It also occurs at the connecting portion between 60.

  In the straight portions of the screw bodies 301 and 302, the overlap length corresponds to the sum of the extension lengths of the extension portions 38a and 38b. In addition, at the shaft ends 32a and 32b that are bent and connected by the universal joint 40, the overlap length on the inner side of the bend exceeds the sum of the extension lengths, while the overlap length on the outer side of the bend. Is smaller than the sum of the extended lengths. By the way, when the screw device 30 is rotationally driven, the position of the extending portion 38 is alternately changed to the inside or outside of the bending. For this reason, the overlap length between the extending portions 38 does not become zero on the outside of the bend, and the pressing surface 36a of the screw body 301 and the pressing surface 36b of the screw body 302 always overlap each other. It is preferable to determine the extension length of the extension portion 38 according to the bending angle of the screw device 30 so that the extension is possible. The bending angle between the screw bodies is 30 degrees or less, preferably 5 to 15 degrees, so that the torque can be satisfactorily transmitted by the universal joint 40.

  As in the present embodiment, by connecting a plurality of identical screw parts 60 to form a screw body, the length of the screw body can be easily adjusted by increasing or decreasing the number of screw parts 60 connected. Can do. For this reason, the screw device 30 can be freely arranged corresponding to the island equipment 100 of various sizes and shapes including straight islands and R islands, while using a shaft joint such as the common screw component 60 and the universal joint 40. Can do.

  In the screw device 30, as an aspect in which the pushing surface 36a of the screw body 301 and the pushing surface 36b of the screw body 302 overlap each other at the shaft ends 32a and 32b, as shown in FIG. Of the blade 34a of the screw body 301 located at the front of the transfer direction, such as a sucking shell, in other words, the push surface 36a of the screw body 302 is arranged so as to overlap the rear of the push surface 36b of the screw body 302 located at the rear of the transfer direction. In contrast to the case where the rear end portion 341 is arranged behind the front end portion 342 of the blade portion 34b of the screw body 302 located rearward in the transfer direction, the push surface 36a of the screw body 301 ahead in the transfer direction is rearward. The screw body 302 can be disposed at the tip of the pushing surface 36b of the screw body 302. The cigarette ends or the like over the screw body a plurality of which are connected by the joint can be continuously provide the transfer force.

Here, the rear end portion 341 of the blade portion 34a means the extension portion 38 when the extension portion 38 is formed to protrude to the rear side of the shaft portion 31a of the screw body 301 (see FIG. 4). When this is not formed, it means the vicinity of the rear end of the blade 34a.
On the other hand, the tip part 342 of the blade part 34b means the extension part 38 when the extension part 38 is formed to protrude on the front side of the shaft part 31b of the screw body 302 (see FIG. 4). When it is not formed, it means the vicinity of the end portion on the front side of the blade portion 34b.
That is, it is not necessary that the extending portions are provided on both of the two screw bodies to be connected, and at least one of the screw bodies may be provided with this. Even when the extending portion 38 is formed only at one of the connecting end portions of the screw bodies, when the extending portion 38 is rotated and positioned outside the bent portion, it overlaps with the connecting end portion of the blade portion of the other screw body. It is preferable that the length of the extending portion 38 is determined so that

  Like the screw device 30 according to the present embodiment, the screw parts 60 are connected to each other in the axial direction to form the screw bodies 301 and 302, respectively, and these are bent by the universal joint 40 and connected to each other. Accordingly, the connecting end portion by the universal joint 40 and the straight portions corresponding to the intermediate portions of the screw bodies 301 and 302 are configured using the common screw part 60 and the screw bodies 301 and 302 having a desired length. be able to.

  In the case of the present embodiment in which the rear end 341 of the front blade portion 34a in the transfer direction is arranged behind the front end portion 342 of the rear blade portion 34b, the rear of the front blade portion 34a is reversed. Compared with the case where the end portion 341 is disposed at the tip of the tip portion 342 of the rear blade portion 34b, the butt that is transferred extends when the abutting position shifts from the pushing surface 36b to the pushing surface 36a. Since it is not necessary to go over the step corresponding to the thickness of the portion 38, there is an advantage that the butt can be delivered smoothly by the screw body on the other side.

In the present embodiment, when the push surface 36a of the screw body 301 located at the front in the transfer direction is arranged behind the push surface 36b of the screw body 302 located at the rear in the transfer direction, the extension portion 38a or The spiral pitch of the push surface in at least one of 38b may be larger than the spiral pitch of the push surface in the region other than the extending portion. That is, as shown in FIG. 5, the angle (θ ₁ ) between the normal direction of the push surface 36 in the extension portion 38 and the axial direction of the shaft portion 31 is the normal line of the push surface in the region other than the extension portion. The rear end portion 341 of the blade portion 34a of the screw body 301 corresponding to the front in the transfer direction is set to be larger than the angle (θ ₂ ) between the direction and the axial direction of the shaft portion, and the screw body 302 corresponding to the rear in the transfer direction. The screw body 301 and the screw body 302 can be directly connected to each other in the axial direction by making the spiral directions of the respective pressing surfaces 36a and 36b coincide with each other while sliding backward from the tip portion 342 of the blade portion 34b.

  At this time, as shown in FIG. 3, the clearance (d1) between the rear end 341 of the blade part 34 and the front end 342 of the screw part 60 positioned in the transfer direction of the cigarette butt 110 or the like is pushed against the conduit 20. It is preferable that the clearance (d0) with the end of the surface 36 is smaller. The minimum size of the butt 110 or the like that can be transferred by the screw device 30 is defined by the clearance (d0) between the inner peripheral surface of the conduit 20 and the peripheral edge of the push surface 36, and dust smaller than this is difficult to transfer by the screw device 30. When a separate transfer means such as a blower is required for recovery, the clearance (d1) between the rear end 341 of the blade 34 and the tip 342 of the other blade 34 connected to the rear of the blade 34 is set. If the size is smaller than this, the butts and the like 110 will not leak out at the connecting portion between the blade portions 34.

  The present invention relates to a collection device 10 for sucking butt or the like for transferring and collecting dust such as cigarette butts and paper waste, and the clearance d0 is determined by the minimum size of the dust to be transferred. Of course, the present invention may be a recovery device that targets only the cigarette butt, or a recovery device that targets only recovery of paper waste and the like.

Further, when the screw device 30 receives torque from the rotary drive device 50 and rotates, the extension portions 38a and 38b are also connected to the shaft portions 31a and 31b at the moment when the connected extension portions 38a and 38b are positioned inside the bend. In the extending portions 38a and 38b, notches 39 are formed on the peripheral surfaces of the shaft portions 31a and 31b, respectively (see FIG. 5). That is, an extension projecting forward from the shaft end 32b is prevented so that the shaft end 32a on the front side which is bent and connected by a universal joint in a “U” shape does not collide with the tip portion 342 of the blade 34b on the rear side. It is preferable to form a notch 39 on the inner diameter side of the protruding portion 38. Similarly, a notch 39 may be formed on the inner diameter side of the rear end portion 341 of the front blade portion 34a that may collide with the rear shaft end 32b.
The width (d2) of the notch 39 is smaller than the clearance (d0) between the conduit 20 and the end of the pressing surface 36 so that the butts or the like that reach the extending portions 38a and 38b do not leak from the notch 39. It is preferable to do.

  The universal joint 40 shown in FIG. 6 is formed by combining joint components 401 and 402 so as to be rotatable with respect to the rotation shafts 43 and 44. The rotating shaft 43 is orthogonal to the axis (CLa) of the joint component 401, and the rotating shaft 44 is orthogonal to the axis (CLb) of the joint component 402. Therefore, the axial center (CLa) of the joint part 401 and the axial direction of the shaft part 31a of one screw body 301 are made to coincide with each other, and both are rotationally fixed, and the axial core (CLb) of the joint part 402 and another screw body By rotating and fixing the two shafts 31b so that they are aligned with each other in the axial direction of the shaft portion 31b, the screw bodies 301 and 302 to be connected can transmit torque to each other regardless of the bending angle.

On the outer peripheral surfaces of the joint components 401 and 402, bosses 45 are formed so as to protrude along the respective shaft cores. The joint parts 401 and 402 are each formed with a through hole 46. On the other hand, a key groove 42 for mounting the boss 45 is formed on the inner peripheral surface of the screw component 60, and a pin insertion hole 41 is provided at a position corresponding to the through hole 46 (see FIG. 5).
Accordingly, one joint component of the universal joint 40 is inserted into the shaft portion 31 of the screw component 60, and the pin is driven in a state where the pin insertion hole 41 and the through hole 46 are aligned, so that both can be easily angled. And can be fixed.

In addition, the screw part 60 has an uneven fitting part 33 formed at the shaft end 32 thereof, and can determine the angle when connected in series with other screw parts, and the torque applied to the shaft part 31. Can be transmitted to the shaft portion of another connected screw part. That is, the screw which makes the unevenness fitting part of one screw part and the unevenness fitting part of another screw part fit together, makes the extension parts 38 overlap by predetermined length, and makes the push face 36 continue. Body assembly work is easy and reproducible. In addition, as shown in FIG. 5, you may share the recessed part of the uneven | corrugated fitting part 33, and the keyway 42. FIG. The specific shape of the concave-convex fitting portion 33 is not particularly limited, and as long as the angle between adjacent screw parts 60 can be determined, a combination of a protrusion and a fitting groove that are detachable in the axial direction as shown in FIG. In addition, a male screw and a female screw that are screwed together may be provided.
Further, when the shaft 70 is not inserted into the screw body 301 and the screw body 301 is divided and configured by the plurality of screw parts 60, the torque applied to the screw body 301 from the rotary drive device 50 is via the uneven fitting portion 33. Since it is transmitted to the other screw parts 60, the uneven fitting part 33 is required to have a predetermined torsional strength.

The spiral angle of the spiral push surface 36 (excluding the extension portion 38) provided in the screw component 60 according to the present embodiment is 270 degrees. Such a helix angle is determined from the following viewpoints.
1) When the screw part 60 is obtained by injection molding of a molten resin such as polyarylate having excellent flame retardancy, if a spiral angle of about 360 degrees or more is given, it is difficult to remove the mold from the mold. On the other hand, when the spiral angle is small, the number of the screw parts 60 is excessive in order to obtain the pressing surface 36 having a predetermined spiral pitch.
2) When the screw parts 60 are connected in series, the formation positions of the extending portions 38 that overlap each other are shifted by 90 degrees around the shaft part 31, so the rigidity balance of the screw device 30 formed by assembling the screw parts 60 Is good.
3) When the spiral angle is 180 degrees or 360 degrees, it is necessary to reverse the concave and convex formation patterns of the concave-convex fitting portion 33 at both ends of the shaft end 32. If the spiral angle is 270 degrees, As shown in FIG. 5, by using the concave / convex fitting portions 33 in which the concave / convex patterns are arranged 90 degrees apart, the same concave / convex fitting portions 33 can be formed at both ends of the shaft end 32. As a result, the screw component 60 can be used with its axial direction reversed, and the assembly workability is excellent.

  The inner peripheral surface of the flange member 21 constituting the conduit 20 has a cross-sectional shape cut perpendicularly to the longitudinal direction so that the clearance with the peripheral edge of the screw body does not become a dead space such as a butt shell, at least downward (bottom) On the side, it is preferable that the distance from the axial center of the screw body is a semicircular arc shape having a uniform curved shape. Further, since it is necessary for the eaves member 21 to communicate with the insertion port 104 and receive the inserted butts or the like, it is preferable to use, for example, a halved cylindrical member opened upward as shown in FIG. In addition, a cylindrical member in which an opening communicating with the charging port 104 is formed in the peripheral surface may be used.

  The conduit 20 that needs to be bent at a predetermined angle together with the screw device 30 according to the present embodiment may be formed by bending the opening surface of one long eaves member into a “U” shape. It can be easily manufactured by connecting a plurality of straight tubular scissors members 21 opened upward at the predetermined angle. Although the length of the collar member 21 can correspond to the length of the screw body accommodated therein, it does not necessarily have to correspond to the length of the screw body individually accommodated.

  That is, in the recovery device 10 such as a butt sucker shown in the same figure, the lengths of the screw bodies 301 to 306 and the flange member 21 that accommodates the screw bodies 301 to 306 are substantially the same, and the arrangement of the universal joint 40 that connects the screw bodies together The position is inside the holding member 24. On the other hand, especially in the case of the conduit 20 with a shallow bending angle, the clearance between the bottom of the inner peripheral surface of the flange member 21 and the peripheral edge of the screw body is equal to or smaller than the outer dimensions of the butterfly shell, and the flange member 21 and the screw body. As long as the condition of not interfering with each other, a plurality of screw bodies may be accommodated in one scissor member 21, and conversely, as a mode of covering one screw body with a plurality of scissors members 21 Also good. In these cases, the arrangement position of the universal joint 40 that couples the screw bodies may be inside the holding member 24 or may be removed from the middle portion of the flange member 21.

  In addition, when connecting the eaves member 21, the end portions of the eaves member 21 are held by the holding member 24 having a special shape in addition to the method in which the respective end portions are cut obliquely and joined to each other. You may attach A specific example of the holding member 24 will be described later.
