Description

  The present invention relates to a tape bundling apparatus for bundling an object to be bundled using a tape.

In recent years, a tape bundling device has been proposed in which air is sucked through a hole formed in a conveyance belt to adsorb and convey the tape to the conveyance belt to form a rectangular loop using the tape (for example, Patent Documents). 1).
Japanese Patent No. 3585926

  However, in Patent Document 1, a single belt is wound around a large number of pulleys and is turned many times. For this reason, the only belt circulates through a very long path bent many times by a pulley. Therefore, the only belt is subject to partial tension. As a result, since an extremely large torque is required as an electric motor for driving the belt, it is necessary to use a large electric motor, and as a result, the bundling device becomes large.

In addition, when a thin film-like resin tape is used as the tape, the end of the tape is likely to curl due to the influence of static electricity or the like in the final process of loop formation. For this reason, there exists a possibility that the loop by a tape cannot be formed favorably.
The present invention has been made in view of the above problems, and in the method of attracting and transporting a tape to a transport belt, curling of the end portion of the tape can be prevented and a tape loop can be satisfactorily formed. An object of the present invention is to provide a small tape bundling device.

In order to achieve the above object, the present invention provides a loop forming mechanism for forming a loop for winding an object to be bound at an end of a tape, a mounting table for mounting the object to be bound, and the above table A tape passage groove through which the tape passes to form the loop, and an upper surface for placing the object to be bound, along the width direction of the tape perpendicular to the tape transport direction, A receiving plate that can advance and retreat in the tape passage groove, a clamp member that presses the overlapped portion of the tape on which the loop is formed, and a lower surface of the receiving plate, and a tape that is longer than the receiving plate in the tape passage groove along the width direction A tape restricting plate capable of advancing and retreating to an upstream position in the transport direction, and a drive mechanism for driving the tape restricting plate to an advance position that advances into the tape passage groove and a retreat position that retreats from the tape passage groove, Loop type above The mechanism is arranged in a polygonal shape so as to be aligned in the transport direction, and includes a plurality of belt transport mechanisms that suck and transport the tape by air suction, each belt transport mechanism extending in parallel with the transport direction and A plurality of endless transport belts arranged with air suction gaps in a direction perpendicular to the transport direction, wherein the plurality of belt transport mechanisms transport the tape along the tape passage groove; The belt that includes a belt conveyance mechanism and conveys the tape along the tape passage groove, and conveys the tape along the tape passage groove when the conveyance belt of the belt conveyance mechanism conveys the tape to form a loop. between the tape regulating plate in the advanced position and the conveyor belt of the transport mechanism, to characterized in that are as passage for tape transport to the receiving plate side is formed It is intended.

  In the conventional case where the only long belt is bent many times through a large number of pulleys, the tension is partially excessive in the long belt. On the other hand, in the present invention, since a plurality of belt conveying mechanisms arranged in a polygonal shape are used, the number of times the belt is bent can be significantly reduced as compared with the conventional one, and as a result, the belt tension can be reduced. It can be remarkably reduced. Therefore, a small electric motor can be used as the electric motor for driving the belt conveying mechanism, and the tape bundling device can be downsized.

Even if the tape is thin and easily curled due to the influence of static electricity or the like, the tape is placed between the transport belt of the belt transport mechanism that transports the tape along the tape passage groove and the tape regulating plate at the advanced position. Therefore, the tape can be prevented from curling and can be transported satisfactorily.
The drive mechanism may include a drive member, a cam that is rotationally driven by the drive member, and a rotating arm that swings to move the tape restricting plate back and forth following the cam. (Claim 2). In this case, by setting the lever ratio of the rotating arm, the stroke amount of the rotating arm can be sufficiently increased even with a small cam. Therefore, even a small drive mechanism can ensure a sufficient amount of advancement / retraction as a tape regulating plate.

  The rotating arm has first and second end portions and is rotatable about the first end portion, and the drive mechanism is configured to have the second end portion of the rotating arm. A slider that is slidable in a predetermined sliding direction and supports the tape restricting plate so as to be able to move together, and a biasing member that biases the tape restricting plate in the advancing direction via the slider. In some cases, the cam is configured to drive the tape restricting plate in the backward direction through the rotating arm against the biasing member.

In this case, the tape restricting plate can be smoothly advanced and retracted by using the slider. Further, since the tape regulating plate is urged in the advance direction by the urging member, it is preferable that the tape passage groove can be mechanically closed when an abnormality occurs.
The plurality of belt conveyance mechanisms may include belt conveyance mechanisms adjacent to each other in the conveyance direction, and the conveyance belts of the belt conveyance mechanisms adjacent to each other in the conveyance direction may be wound around a common pulley. (Claim 4). In this case, the distance between the tape conveyance surfaces of the conveyance belts of the belt conveyance mechanisms adjacent to each other can be reduced. The direction of the tape in the vicinity of the pulley can be favorably changed.

Further, there may be provided a guide member for urging the direction change of the tape from one of the belt conveyance mechanisms adjacent to each other in the conveyance direction to the other. In this case, the direction of the tape can be favorably changed from one of the belt conveying mechanisms adjacent to each other to the other by the guide member.
The guide member includes an annular member provided on the same axis of the pulley so as to be able to rotate along with the pulley. The annular member has a larger diameter than the pulley, and the outer circumference of the annular member causes In some cases, the direction of the tape is urged from one to the other of the belt conveying mechanisms adjacent to each other.

In this case, the annular member arranged on the same axis of the pulley around which the conveyance belts of the belt conveyance mechanisms adjacent to each other are wound in common rotates together with the pulley. Therefore, when the annular member changes the direction of the tape, the relative speed between the outer periphery of the annular member and the tape is small. As a result, the annular member does not give sliding resistance to the tape so as to prevent the tape from being conveyed.
In addition, for example, even when the tape is adsorbed to the outer periphery of the annular member due to moisture adhering to the tape when bundling other materials containing tofu or other moisture, the annular member rotates along with the pulley, so the tape Can be satisfactorily conveyed to the next belt conveying mechanism side.

  Therefore, when a polygonal loop is formed by sucking and transporting the tape to the transport belt, the tape loop can be satisfactorily formed. As a result, it is possible to satisfactorily bind to-be-bound objects containing tofu and other moisture, and to bind to-to-be-bound objects using a tape that is easily electrostatically attracted. Moreover, it is only necessary to arrange an annular member on the pulley, and the structure is simple.

  The loop forming mechanism includes a negative pressure groove forming frame that forms a negative pressure groove communicating with the gap, and the guide member is fixed to the negative pressure groove forming frame and faces an outer periphery of the common pulley. Including a main body and a guide piece extending from the main body into the gap, the guide piece having an inclined guide surface that is inclined with respect to the transport direction and is capable of contacting an end of the tape in the transport direction. (Claim 7). In this case, although a fixed mold is used as the guide member, the guide piece is inclined into the gap between the conveyance belts, so the end of the tape conveyed by the conveyance belt collides with the end surface of the guide piece. There is nothing. That is, the end portion of the tape is smoothly peeled off from the transport belt by the inclined guide surface of the guide piece, and is successfully delivered to the next belt transport mechanism.

In some cases, the transport belts of the belt transport mechanisms adjacent to each other in the transport direction are arranged symmetrically with respect to the center position in the width direction of the tape. In this case, since the tape can be adsorbed to the transport belt without deviation, it can be transported satisfactorily.
Moreover, each said conveyance belt of each said belt conveyance mechanism may be a toothed belt wound around a toothed pulley. In this case, since the conveyance belt made of a toothed belt does not cause a shift with respect to the toothed pulley, an excessive tension is not applied to the conveyance belt. Therefore, a small motor can be used as a motor for driving the belt conveying mechanism, and the tape bundling device can be downsized.

A cam follower 88 that moves up and down with the body 87, an urging member 89 made of, for example, a tension coil spring that urges the support 87 downward, and is fixed to the upper part of the support 87 and abuts against the lower surface of the receiving plate 18. And a possible horizontal bar-shaped second clamp 90.

By pushing up by the cam 63, the support body 87 and the heater 84 are moved up against the biasing member 89, and the end portion Ta of the tape T is sandwiched between the second clamp 90 and the lower surface of the receiving plate 18. It has become so.
Referring to FIG. 19A, the receiving plate 18 extends in the front-rear direction and is driven back and forth by the drive mechanism 91. The drive mechanism 91 includes a guide shaft 93 having one end fixed to a support block 92 fixed to the apparatus main body 2 and extending in the front-rear direction. A rear end 18 b of the receiving plate 18 is fixed to a movable body 94 that is supported by the guide shaft 93 so as to be movable in the axial direction of the guide shaft 93. The movable body 94 has an insertion hole 94a through which the guide shaft 93 is slidably inserted. A stopper 101 that prevents the movable body 94 from being detached from the guide shaft 93 is provided at the rear end of the guide shaft 93.

The support block 92 has a receiving plate insertion groove 95 that supports the receiving plate 18 so as to be slidable back and forth. The front end 18 a of the receiving plate 18 advances forward through the receiving plate insertion groove 95.
The drive mechanism 91 includes an electric motor 96 as a drive member supported by the apparatus main body 2, a rotation member 97 that rotates along with a rotation shaft 96 a of the electric motor 96, the rotation member 97, and the movable body. 94, and a connecting arm 98 that connects to the main body 94. One end 98 a of the connecting arm 98 is rotatably connected to the movable body 94 via the pivot 99, and the other end 98 b of the connecting arm 98 is rotatably connected to the rotating member 97 via the pivot 100. Yes. The pivot 100 is disposed at a position separated from the rotation shaft 96 a of the electric motor 96 by a predetermined distance in the rotation member 97.

The crank mechanism using the rotating member 97 and the connecting arm 98 converts the rotational motion of the electric motor 96 into the linear motion of the plate 18 so that it can cope with the case where the wide tape T is used. A large amount of movement is secured.
In order to receive the object A to be bound, the receiving plate 18 is advanced and retracted to an advanced position where it advances into the tape passage groove 4 as shown in FIG. 19B and a retreat position where it retracts from the tape passage groove 4 as shown in FIG. 19A. It is like that.

  Referring to FIG. 20, the conveyance roller 31 of the supply mechanism 9 and the first pulley 41 of the first belt conveyance mechanism 11 are driven by the electric motor 114 as the same drive member. That is, a pulley 111 that can be coaxially rotated with the conveying roller 31 and a pulley 112 that can be coaxially rotated with the first pulley 41 of the first belt conveying mechanism 11 are provided. An endless belt 113 is wound around 111 and 112.

  When the pulley 111 is driven by the electric motor 114 as a driving member, the conveying roller 31 of the supply mechanism 9 is driven, and the conveying belt 32 is driven by being driven by the conveying roller 31. By driving the pulley 112 via the belt 113, the first pulley 41 of the first belt transport mechanism 11 is driven. That is, the first pulley 41, which is a pulley at the start of the belt conveyance mechanisms 11 to 14, is driven, and the entire belt conveyance mechanisms 11 to 14 are thereby driven.

As a result, the end portion Ta of the tape T is sequentially conveyed to the first belt conveyance mechanism 11, the second belt conveyance mechanism 12, the third belt conveyance mechanism 13, and the fourth belt conveyance mechanism 14, which will be described later. As shown in FIG. 22A, a loop TL of the tape T is formed.
Next, the tape bundling operation 1 of the tape bundling apparatus will be described.

First, as shown in FIG. 21A, after the receiving plate 18 has advanced into the tape passage groove 4, the tape regulating plate 35 has advanced into the tape passage groove 4 as shown in FIG. 21B. A tape transport path 60 is formed between the tape regulation plate 35 that has advanced and the transport belt of the fourth belt transport mechanism 14.
Next, the transport roller 31 and the transport belt 32 of the supply mechanism 9 rotate forward, and the tape T is supplied to the loop forming mechanism 6. Along with this, the air suction pump 8 is driven, and negative pressure is generated in the frames 21 to 24 of the negative pressure groove forming frame 7. Simultaneously with the driving of the transport roller 31, the belt transport mechanisms 11 to 14 are driven to form a loop TL of the tape T as shown in FIG. At this time, as described above, the end portion Ta of the tape T passes through the tape transport passage 60, so that curling of the tape T can be prevented.

Further, the tape restricting plate 35 is disposed in the formed loop TL. However, as it is, the tape restricting plate 35 is obstructed when the tape T is drawn, and as shown in FIG. Is withdrawn outside the loop TL. That is, it is retracted from the tape passage groove 4 to below the rear portion 3 b of the table 3.
Next, as shown in FIG. 23A, the end portion Ta of the tape T is sandwiched between the raised first clamp 68 and the receiving plate 18 of the first clamp mechanism / cutting mechanism 15.

  Next, as shown in FIG. 23B, the object to be bound A is placed on the receiving plate 18. Next, the driving of the air suction pump 8 is stopped, the suction of the belt transport mechanisms 11 to 14 to the transport belt 19 is released, and the transport roller 31 and the transport belt 32 are reversed, whereby As shown to 24A, the loop TL is drawn and the tape T becomes a shape along the circumference | surroundings of the to-be-bound object A. FIG.

Next, as shown in FIG. 24B, the overlapped portion Tb of the tape T is sandwiched between the second clamp 90 that has been raised by the second clamp mechanism 17 and the lower surface of the receiving plate 18. Next, as shown in FIG. 24C, the heater 84 raised by the heating mechanism 16 is heated while pressing the overlapping portion Tb of the tape T against the lower surface of the receiving plate 18, and the overlapping portion Tb of the tape T is heated and fused.
Although not shown in the figure, the raised cutter 70 of the first clamping mechanism / cutting mechanism 15 cuts the extra length portion of the tape T at almost the same timing as the operation of the heater 84 or slightly delayed, and the binding is completed.

  According to the present embodiment, the following operational effects are obtained. That is, in the conventional case where the only long belt is bent many times through a large number of pulleys, the tension is partially excessive in the long belt. On the other hand, in the present embodiment, since a plurality of belt conveyance mechanisms 11 to 14 arranged in a polygonal shape are used, the number of bendings of the conveyance belt 19 can be significantly reduced as compared with the prior art. As a result, the tension of the transport belt 19 can be significantly reduced. Therefore, it is possible to use a small motor as the electric motor 114 for driving the belt conveying mechanisms 11 to 14, and the tape bundling device 1 can be downsized.

Further, even for a thin tape T that is likely to be curled due to the influence of static electricity or the like, the transport belt 19 of the fourth belt transport mechanism 14 that transports along the tape passage groove 4 and the tape regulating plate 35 at the advanced position Since the tape T is transported through the tape transport path 60 formed between the two, the curling of the tape T can be prevented and transported satisfactorily.
Since the tape restricting plate 35 is advanced and retracted by the rotating arm 55 rotated by the cam 58, the distance from the rotation center (fulcrum) of the rotating arm 55 to the cam 58 (power point) and the rotation of the rotating arm 55. By setting the distance from the moving center (fulcrum) to the engagement portion 57 (operation point), it is possible to obtain a remarkably large lever ratio with respect to the displacement amount of the engagement portion 58b of the cam 58 in the front-rear direction. . Therefore, even if it is small, the stroke amount of the second end 55b of the rotating arm 55 can be increased. Therefore, even with a small drive mechanism, a sufficient amount of advancement / retraction can be secured as the tape regulating plate 35.

Further, by using the slider 47, the tape restricting plate 35 can be smoothly advanced and retracted. Further, since the tape restricting plate 35 is urged in the advance direction by the urging member 54, it is preferable that the tape passing groove 4 can be mechanically closed by the tape restricting plate 35 when an abnormality occurs.
Further, since the conveyance belt 19 of the adjacent first and second belt conveyance mechanisms 11 and 12 is wound around the common second pulley 42, it is between the first and second belt conveyance mechanisms 11 and 12. Thus, the distance between the tape transport surfaces 19a of the transport belts 19 can be reduced. Therefore, the direction change of the tape T can be satisfactorily performed in the vicinity of the second pulley 42.

Further, the conveyance belts 19 of the adjacent second and third belt conveyance mechanisms 12, 13 are wound around a common third pulley 43, and the adjacent third and fourth belt conveyance mechanisms 13, 14 are wound. Since the conveyor belt 19 is wound around the common fourth pulley 44, the same effect can be obtained.
An annular plate 26 that rotates along with the second pulley is arranged on the same axis as the second pulley 42 around which the conveyance belts 19 of the first and second belt conveyance mechanisms 11 and 12 adjacent to each other are wound in common. Has been. An annular plate 26 that rotates along with the third pulley 43 is coaxial with the third pulley 43 around which the conveyance belts 19 of the second and third belt conveyance mechanisms 12 and 13 adjacent to each other are wound in common. Has been placed. An annular plate 26 that rotates along with the fourth pulley 44 is coaxial with the fourth pulley 44 around which the conveyance belts 19 of the third and fourth belt conveyance mechanisms 13 and 14 adjacent to each other are wound in common. Has been placed.

  For example, as shown in FIGS. 8A and 8B, an annular plate disposed on the same axis as a third pulley 43 around which the conveyance belts 19 of the second and third belt conveyance mechanisms 12 and 13 adjacent to each other are wound in common. 26 rotates together with the third pulley 43. Therefore, when the annular plate 26 changes the direction of the tape T, the relative speed between the outer periphery 26a of the annular plate 26 and the tape T is small. As a result, the annular plate 26 does not give a sliding resistance that prevents the tape T from being conveyed.

  Further, for example, even when the tape T is adsorbed to the outer periphery 26a of the annular plate 26 due to moisture adhering to the tape T when binding the binding object A containing tofu or other moisture, the annular plate 26 is not connected to the third pulley. Since the rotation is accompanied with the belt 43, the tape T can be favorably transported to the next third belt transport mechanism 13 side. This is also effective when the thin tape T is electrostatically attracted to the peripheral surface of the annular plate 26.

  Therefore, when forming the rectangular loop TL by sucking and transporting the tape T to the transport belt 19, the loop TL by the tape T can be formed satisfactorily. As a result, it can perform well also when binding the to-be-bound object A containing tofu and other water | moisture contents, and binding using the tape T which is easy to carry out electrostatic adsorption. In addition, the structure is simple because only the annular plate 26 is provided on each of the pulleys 42 and 43.

  The plurality of transport belts 19 of the first and second belt transport mechanisms 11 and 12 are arranged symmetrically with respect to the center position TW1 in the width direction TW of the tape T perpendicular to the transport direction L1 of the tape T. ing. Therefore, the tape T can be adsorbed to the transport belt 19 of each belt transport mechanism 11 and 12 without deviation and can be transported satisfactorily. The same applies to the other belt conveyance mechanisms 13 and 14.

Further, the conveyance belts 19 of the first and second belt conveyance mechanisms 11 and 12 are alternately arranged with respect to the axial direction X1 of the second pulley 42, and each annular plate 26 is arranged between the adjacent conveyance belts 19. Therefore, the direction change of the wide tape T can be performed satisfactorily. The same applies to the annular plate 26 of the third pulley 43.
The annular plate 26 may be formed integrally with the pulleys 42 and 43 with a single material, or the annular plate 26 made of a different member may be attached to the pulleys 42 and 43.

  Moreover, since each conveyance belt 19 of each belt conveyance mechanism 11-14 consists of the toothed belt wound around the pulleys 41-45 which consist of a toothed pulley, the conveyance belt 19 is with respect to a toothed pulley. , No deviation occurs. Therefore, excessive tension is not applied to the conveyor belt 19. Also from this point, it is possible to use a small electric motor as the electric motor 114 for driving the belt conveyance mechanisms 11 to 14, and the tape bundling device 1 can be downsized.

  The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the second pulley 42 is used as a guide member that promotes the direction change of the tape T from the second belt conveyance mechanism 11 adjacent to the conveyance direction L1 to the second belt conveyance mechanism 12. Although the annular plate 26 that rotates together is used, a fixed guide plate 260 as shown in FIG. 25 may be used instead of the annular plate 26.

The fixed guide plate 260 as a guide member has a curved main body 261, a guide piece 262 extending from the main body 261 in opposite directions, and a pair of guide pieces 263. The main body 261 is fixed to the negative pressure groove forming frame 7 and faces the outer periphery of the second pulley 42 as a common pulley.
The guide piece 262 extends from the center in the width direction of the main body 261 into the gap S between the two transport belts 19 of the first belt transport mechanism 11. The pair of guide pieces 263 are disposed on both sides of the second belt conveyance mechanism 12 with the two conveyance belts 19 interposed therebetween.

Each of the guide pieces 262 and 263 has an inclined guide surface 264 that is inclined with respect to the transport direction L1 of the tape T and can contact the end portion Ta in the transport direction L1 of the tape T.
In this embodiment, although the fixed guide plate 260 is used as the guide member, the guide piece 262 of the fixed guide plate 260 is inclined into the gap S between the transport belts 19, so that it is transported by the transport belt 19. The end portion Ta of the tape T does not collide with the end surface of the guide piece 262. That is, the end portion Ta of the tape T is smoothly peeled off from the transport belt 19 of the second belt transport mechanism 12 by the inclined guide surface 264 of the guide piece 262, and is moved to the transport belt 19 of the second belt transport mechanism 12.
