Definitions

  • the present invention relates to a tape binding device that binds a material to be bound using a tape.
  • the conveyance directions of the tapes must be changed at right angles thereto.
  • curved guide plates for direction change are provided at the corners of the rectangular loop.
  • the belt is wound around the respective outer sides of the pulleys. Therefore, the length of the fixed guide plate for direction change is increased. Since an end of the tape slides relative to the long fixed guide plate, the end of the tape that receives sliding resistance is easily prevented from being conveyed.
  • the tape may be absorbed to the long fixed guide plate by the water that has attached to the tape. Furthermore, when the tape is in a thin film shape, it may be electrostatically absorbed to the long fixed guide plate. In these cases, the loop of the tape cannot be satisfactorily formed.
  • An object of the present invention is to provide a small-sized tape binding device capable of satisfactorily forming a loop of a tape when the loop is formed by conveying the tape using air suction.
  • the present invention includes a loop forming mechanism for forming a loop for winding a material to be bound at an end of a tape.
  • the loop forming mechanism includes a plurality of belt conveying mechanisms arranged in a polygonal shape in a conveyance direction for absorbing the tape by air suction and conveying the tape.
  • Each of the belt conveying mechanisms includes a plurality of endless conveying belts extending parallel to the conveyance direction and arranged in a direction perpendicular to the conveyance direction with a space for air suction provided therebetween.
  • the tension of the longitudinal belt is partially excessive.
  • the plurality of belt conveying mechanisms arranged in a polygonal shape are used. Therefore, the number of times of bending the belt can be made significantly reduced, as compared with the conventional case. As a result, the tension of the belt can be significantly reduced. Therefore, a small-sized electric motor can be used as an electric motor for driving the belt conveying mechanisms, and thus the tape binding device can be miniaturized.

  • the pair of vertical frames 22 and 24 and the upper frame 23 are arranged above the table 3, and the lower frame 21 is arranged below the table 3.
  • the first belt conveying mechanism 11 is accommodated within the lower frame 21
  • the second belt conveying mechanism 12 is accommodated within the right vertical frame 22
  • the third belt conveying mechanism 13 is accommodated within the upper frame 23
  • the fourth belt conveying mechanism 14 is accommodated within the left vertical frame 24.

  • the following function and effect are produced. That is, in the conventional case where only one elongate belt is bent many times through a large number of pulleys, the tension of the longitudinal belt is partially excessive.
  • the plurality of belt conveying mechanisms 11 to 14 arranged in a polygonal shape are used. Therefore, the number of times of bending of the conveying belt 19 can be reduced significantly, as compared with the conventional case. As a result, the tension of the conveying belt 19 can be significantly reduced. Therefore, a small-sized motor can be used as the electric motor 115 for driving the belt conveying mechanisms 11 to 14, and thus the tape binding device 1 can be miniaturized.
  • the conveying belts 19 in the adjacent first and second belt conveying mechanisms 11 and 12 are wound around the common second pulley 42, the distance between the tape conveying surfaces 19a of the conveying belts 19 can be brought closer to each other between the first and second belt conveying mechanisms 11 and 12. Therefore, it is possible to satisfactorily change the direction of the tape T in the vicinity of the second pulley 42.
  • the annular plate 26 that rotates together with the common second pulley 42 around which the conveying belts 19 in the adjacent first and second belt conveying mechanisms 11 and 12 are wound is arranged coaxially with the second pulley 42.
  • the annular plate 26 that rotates together with the common third pulley 43 around which the conveying belts 19 in the adjacent second and third belt conveying mechanisms 12 and 13 are wound is arranged coaxially with the third pulley 43.
  • the annular plate 26 that rotates together with the common fourth pulley 44 around which the conveying belts 19 in the adjacent third and fourth belt conveying mechanisms 13 and 14 are wound is arranged coaxially with the fourth pulley 44.
  • the annular plate 26 arranged coaxially with the common third pulley 43 around which the conveying belts 19 in the adjacent second and third belt conveying mechanisms 12 and 13 are wound rotates together with the third pulley 43.
  • the annular plate 26 changes the direction of the tape T, therefore, a relative speed between the outer periphery 26a of the annular plate 26 and the tape T is low.
  • the annular plate 26 does not impose on the tape T such sliding resistance as to prevent the tape T from being conveyed.
  • the tape T can be satisfactorily conveyed toward the next third belt conveying mechanism 13 because the annular plate 26 rotates together with the third pulley 43. This is also effective when a thin tape T is electrostatically absorbed to a peripheral surface of the annular plate 26.
  • the loop TL of the tape T can be satisfactorily formed.
  • the loop TL can be also satisfactorily formed when the material to be bound A including water such as tofu is bound and when the material to be bound A is bound using the tape T that is easy to be electrostatically absorbed.
  • the annular plate 26 may be only disposed in each of the pulleys 42, 43, and 44. Therefore, the configuration is simple.
  • the plurality of conveying belts 19 in each of the second and third belt conveying mechanisms 12 and 13 are symmetrical with respect to the center position TW1 in the width direction TW of the tape T perpendicular to the conveyance direction L1 of the tape T. Therefore, the tape T can be absorbed to the conveying belts 19 in each of the belt conveying mechanisms 11 to 13 uniformly, and can be satisfactorily conveyed. The same is true for the other belt conveying mechanisms 11 and 14.
  • the annular plate 26 may be formed of a single material integrally with each of the pulleys 42, 43, and 44. Alternatively, the annular plate 26 composed of another member may be attached to each of the pulleys 42, 43, and 44.
  • the conveying belts 19 in the belt conveying mechanisms 11 to 14 are respectively composed of toothed belts wound around the pulleys 42, 43, and 44 composed of toothed pulleys. Therefore, the conveying belt 19 is not shifted from the toothed pulley. Therefore, no excessive tension is applied to the conveying belt 19. From this point, a small-sized electric motor can be also used as the electric motor 115 for driving the belt conveying mechanisms 11 to 14, and thus the tape binding device 1 can be miniaturized.
  • the present invention is not limited to the above-mentioned embodiment.
  • the annular plate 26 that rotates together with the third pulley 43 is used as a guiding member for forcing the direction of the tape T to be changed from the second belt conveying mechanism 12 to the third belt conveying mechanism 13, which are adjacent to each other in the conveyance direction L1
  • the annular plate 26 may be replaced with a fixed guide plate 260 as shown in Fig. 20 .
  • the fixed guide plate 260 as a guiding member includes a main body 261 and a plurality of guiding pieces 262.
  • the main body 261 is opposed to the outer periphery of the third pulley 43 fixed to the negative pressure groove formation frame 7 and serving as a common pulley.
  • the guiding piece 262 extends into the space S between the conveying belts 19 from the main body 261.
  • the guiding piece 262 has an inclined guiding surface 262 that is inclined in the conveyance direction L1 of the tape T and is abuttable to the end Ta in the conveyance direction L1 of the tape T.
  • the guiding piece 262 in the fixed guide plate 260 enters the space S between the conveying belts 19 in an inclined manner, as shown in Fig. 21 . Therefore, the end Ta of the tape T conveyed by the conveying belt 19 does not collide with an end surface of the guiding piece 262. That is, the end Ta of the tape T is smoothly stripped from the conveying belt 19 in the second belt conveying mechanism 12 by the inclined guiding surface 263 of the guiding piece 262, and is satisfactorily delivered to the conveying belt 19 in the third belt conveying mechanism 13.
  • a groove 29 extending in the width direction W1 perpendicular to the conveyance direction L1 of the conveying belt 19 may be formed on the tape conveying surface 19a of the conveying belt 19, as shown in Fig. 22 .
  • the tape T can be absorbed over the whole area in the width direction W1 of the conveying belt 19.
  • the tape T in a small amount enters the groove 29 in a convex manner, as shown in Fig. 23 . Therefore, the capability of the conveying belt 19 to convey the tape T can be enhanced, which allows the tape T to be satisfactorily conveyed without slipping.
  • the groove 29 may be inserted through at least one of the pair of spaces S with the conveying belt 19 held therebetween.
