Description

  The present invention relates to a bundling device for winding and bundling adhesive tape.

  For example, in the work of binding and fixing grapes, cucumbers, etc., especially horticulture, crop branches and vines, to splints or tension cords, etc. A method of winding a tape using a good tape such as vinyl and fixing both ends of the tape with a binding needle or staple is known (for example, Patent Document 1).

  However, this method has a serious problem of environmental pollution because vinyl, binding needles and staples do not rot on the land of farms and fields and remain until later.

For this reason, conventionally, a method of winding an object to be bound using a paper adhesive tape and bonding both ends of the adhesive tape is also known (for example, Patent Document 2).
According to this method, since the tape is made of paper and no binding needles or staples are used, the above-described problem of environmental pollution can be prevented.

JP 2001-055203 A JP 2002-284115 A

However, in the method using an adhesive tape, the tape surface cannot be slid against the object to be bound such as a vine or a branch, so that the tape is wound in a slack state, and the tight binding is not performed. There was a problem that the branches were easily separated from the splint by wind.
For this reason, in order to bind tightly, it was wound manually, but it was the current situation.

  The present invention provides a bundling device capable of tightly bundling around an object to be bundled without loosening while using an adhesive tape so that both ends of the tape can be fixed by adhesion without using a bundling needle or staple. It is an object.

In order to achieve the above object, the binding device of the present invention comprises:
A tape holding portion that is provided on the substrate and rotatably holds a winding body of the adhesive tape; an accommodation portion that is provided on one end side of the substrate and can accommodate a bundled object from an opening; and A tape end processing device that is provided closer to the opening than the accommodating portion of the substrate and sandwiches or opens a free end of the tape, and is provided in a linearly movable manner from the accommodating portion side of the substrate to the tape holding portion side. A plate, an arm rotatably attached to the plate, a plate moving device for moving the plate in a linear direction, an arm rotating device for rotating the arm, and a straight line for detecting the position of the plate A position detection device; a rotation position detection device for detecting a rotation position of the arm; and the plate moving device based on detection signals from the linear position detection device and the rotation position detection device. And a control unit for driving and controlling the fine arm rotating device,
A free end of the tape is clamped by a tape end processing device, a tape intermediate portion between the free end of the tape and the wound body is slidably held at a tip portion of the arm, and the plate moving device and After the arm rotating device is driven and the tape is extended, the tape intermediate portion is moved around the object to be bound in the housing part and wound around the object to be bonded. The tape processing apparatus is characterized in that the tape intermediate portion is cut and the free end of the cut tape is clamped.

  Since it did in this way, since the tape which has adhesiveness with bad slip with respect to a to-be-bundled material is wound so that the circumference | surroundings of a to-be-bundled material may be surrounded in the expansion | extension state, it can bind firmly.

Hereinafter, an embodiment of a binding device of the present invention will be described based on the drawings.
FIG. 1 shows a schematic configuration of a bundling device according to an embodiment of the present invention.

In FIG. 1, cover plates 2 and 3 are fixed to both sides of the substrate 1 in parallel with the substrate 1.
A columnar receiving shaft 4 for mounting the tape A rotatably is erected on the upper right corner of FIG.

As shown in FIGS. 2 and 13, the substrate 1 is provided with two parallel long holes 5 and 6 in the lateral direction in a wide portion below the receiving shaft 4.
As shown in FIG. 2, a plate 10 is slidably mounted in the lateral direction on the same surface side of the receiving shaft 4 of the substrate 1 by pins 7 and 8 fitted in the long holes 5.

  Further, a shaft 11 is fitted into the long hole 6, and the shaft 11 is rotatably attached to the plate 10.

As shown in FIG. 13, a plate moving device that moves the plate 10 in the horizontal direction is provided on the back surface of the substrate 1.

  A crank 16 is rotatably connected to one end of a crank 15 that rotates integrally with the output gear 14, and an end of the crank 16 is rotatably attached to the shaft 11.

Therefore, since the shaft 11 moves along the elongated hole 6 according to the rotation of the motor 12, the plate 10 moves laterally together with the shaft 11.
The position of movement along the long hole 6 of the shaft 11 is detected by a contact type or photoelectric type detection device (shown by reference numeral 131 in FIG. 23) provided on the substrate 1. Therefore, the horizontal position of the plate 10 is detected by this.

The plate 10 is provided with an arm rotation device that rotates the operation arm 23 and the guide arm 28.
That is, as shown in FIG. 2, the plate 10 is provided with a reduction gear device 21 for reducing the rotation of the motor 20 and its output shaft (worm gear) 20a.
The output gear 22 is rotatably attached to the shaft 11.

An operating arm 23 that rotates integrally with the output gear 22 is attached to the shaft 11. A pushing plate 24 and a cutting plate 25 are fixed to the distal end of the operating arm 23 in parallel with each other.
Further, a guide arm 28 is rotatably attached to the shaft 11 so as to overlap the operating arm 23.

A plurality of tape guide rollers 29 are provided upright at the tip and middle of the guide arm 28.
The guide arm 28 is urged clockwise (in FIG. 2) by a spring 30 with one end locked to the operating arm 23 and abuts against the stopper 26 of the operating arm 23.

  The rotation angle of the output gear 22 is detected by a detection device (not shown) provided on the plate 10 (indicated by reference numeral 132 in FIG. 23).

  A semicircular cutout 31 is provided in the upper left part of the substrate 1 (in FIG. 2) to accommodate the objects to be bound, and a tape for sandwiching and cutting the tape in the upper left corner 1a. A processing device 32 is provided.

The tape processing device 32 is configured as follows.
That is, in the upper corner portion 1a of the substrate 1, two parallel cutting plates 33 and 34 in the vertical direction are erected at the outer position, and the holding plate 35 in the vertical direction is provided on the notch 31 side. It is erected.
Between the flat plate 34 and the flat plate 35, a clamping operation plate 36 is attached to the upper corner 1a so as to be rotatable by a shaft 37.

As shown in FIG. 6, the sandwiching operation plate 36 has an L-shaped bent portion 36a extending, and a spring 38 is attached between the bent portion 36a and the flat plate 33. It is biased counterclockwise (in FIG. 6) about the support shaft 37.
As shown in FIGS. 2 to 4 and 12, the tip 36 b of the clamping operation plate 36 is in contact with the tip 35 a of the flat plate 35.

  As shown in FIGS. 2, 11, and 12, a rotating member 40 is provided by a shaft 41 provided on the substrate 1 on the lower side of the flat plate 33, 34, 35, and the sandwiching operation plate 36 (on the substrate 1 side). It is rotatably attached and is urged clockwise (in FIG. 2) by a spring 42.

As shown in FIG. 12, a protrusion 36c is provided at the front end 36b of the clamping operation plate 36 in the direction of the rotating member 40, and an engagement protrusion 36d is provided laterally from the front end of the protrusion 36c. .
As shown in FIGS. 2 to 4 and 12, in the state where the flat plate 35 and the front end of the clamping operation plate 36 are in close contact with each other, the rotating member 40 is biased in the direction of the arrow. 43 abuts on the engaging projection 36d of the clamping operation plate 36.

  As shown in FIG. 12, a release member 50 is provided between the rotating member 40 and the substrate 1 so as to be slidable in the vertical direction along the substrate 1. The upper corner portion 1a protrudes downward from the lower side edge portion 1b in the horizontal direction, and the other end of the abutting portion 52 (see FIG. 3) is in contact with the bent portion 36a of the clamping operation plate 36.

  Therefore, in the state of FIG. 12, as shown in FIG. 5, when the projecting edge 51 is pushed in the direction of the arrow shown in FIG. Pushes the bent portion 36a upward, so that the clamping operation plate 36 rotates clockwise as shown in FIGS. 5 and 11 against the urging force of the spring 38.

  As a result, the protrusion 43 of the rotating member 40 is disengaged from the engaging protrusion 36 d, and the rotating member 40 is rotated in the direction of the arrow (FIG. 11) by the urging force of the spring 42 and contacts the protruding edge 51. In this state, since the protrusion 43 is in contact with the back surface of the protruding portion 36c of the clamping operation plate 36, the operation arm 23 is moved downward as shown in FIG. 6, and the pressing in the arrow direction shown in FIG. However, the clamping operation plate 36 cannot be returned and is maintained in an open state with the flat plate 35.

  In the state of FIG. 11, as shown in FIG. 7, when the front end protrusion 44 of the rotating member 40 is pushed in by the front end edge plate 23 a of the operating arm 23, the protrusion 43 is deeper than the protrusion 36 c of the clamping operation plate 36. Since it moves to the side (in FIG. 11) and disengages from the protrusion 36c, the clamping operation plate 36 is restored by the urging force of the spring 38, and is in the closed state of FIG.

As shown in FIGS. 14 and 15, a base 60 having legs 61, 61 is attached to the back surface of the substrate 1 in parallel with the substrate 1.
An operation member 63 is rotatably attached to the back surface of the base 60 by a shaft 62.
A lever locking body 64 at one end of the operating member 63 protrudes from the hole 65 of the base 60 to the upper surface side of the base 60.

Further, the operating rod body 66 is fixed to the operating member 63 so as to protrude from the hole 65 to the upper surface side of the base 60.
The actuating member 63 is biased counterclockwise (in FIG. 14) about the shaft 62 by a spring 67.

As shown in FIGS. 16 and 17, the operation lever 70 is rotatably attached to the upper surface of the base 60 by a shaft 71 (the operating rod body 66 is in contact with the upper surface of the operation lever 70).
The operation lever 70 is biased counterclockwise (in FIG. 16) by a spring 72 (a part of which is disposed on the back side of the base 60 through the hole 61a of the leg 61).

A gear portion 73 is provided at the upper end of the operation lever 70 along an arc centered on the shaft 71.
The operation lever 70 is provided with a notch 74 into which the lever locking body 64 of the operating member 63 is fitted.

A rotor 77 having a gear portion 76 that meshes with the gear portion 73 is in contact with the upper surface of the base 60 and is rotatably attached by a shaft 78. At one end of the rotor 77, a protruding piece 79 is erected in the vertical direction.
On the back surface of the substrate 1 is provided a detector 80 that comes into contact when the operation lever 70 is operated as shown in FIG.

  As shown in FIG. 18, a shutter 81 is rotatably attached to the base 60 by the same shaft 78 in contact with the upper surface of the rotor 77. When the front end side of the shutter 81 is closed, an arcuate portion 81a is formed so as to form a circular space together with the notch 31 of the substrate 1 as shown in FIG.

  The shutter 81 is urged clockwise (in FIG. 18) by the spring 82, and the corner portion 83 abuts against the bending tip portion 66 a of the operating rod body 66 to rotate the operating member 66 clockwise against the urging force of the spring 67. It is pushing in the direction.

As shown in FIG. 19, an arcuate plate 90 having a fitting recess 92 (see FIG. 21) having a substantially arcuate shape is pivoted by a shaft 91 on the opposite side of the arcuate portion 81 a of the shutter 81. It is attached.
The arcuate plate 90 is biased counterclockwise (in FIG. 19) about the shaft 91 by a spring 93.

A disc 100 is rotatably attached to the upper surface of the shutter 81 by the same shaft 78.
The disc 100 has a tongue piece 101 extending in the radial direction, and a notch 101 a with which a protrusion 79 of the rotor 77 can be engaged is provided on one side of the tongue piece 101.

Further, an ear piece 102 that protrudes in a substantially radial direction at a different position in the circumferential direction of the disc 100 and can be engaged with the fitting recess 92 of the arcuate plate 90 is provided. A projecting body 102a is provided vertically.
The spring 103 biases the projecting piece 79 of the rotor 77 and the projecting body 102a away from each other in the circumferential direction.

  As shown in FIG. 19, when the shutter 81 is open, the arcuate plate 90 receives a counterclockwise biasing force by the spring 93, so that the ear piece 102 of the disc 100 is fitted in the fitting recess 92. Has been.

  In the state of FIG. 19, when the handle 1 d of the substrate 1 is gripped by hand and the lower end portion of the operation lever 70 is rotated clockwise against the urging force of the spring 72, the rotor in which the gear portions 73 and 76 are engaged with each other. 77 rotates counterclockwise (in FIG. 19), and this turning force is applied to the protrusion 102a of the ear piece 102 of the disc 100 via the spring 103, and this turning force is engaged with the ear piece 102. Added to the arcuate plate 90.

Since the force applied to the arcuate plate 90 similarly acts on the shaft 91, the shutter 81 rotates counterclockwise around the shaft 78 against the spring 82 (at the same time, the rotor 77 and the disc 100). The arcuate plate 90 also rotates integrally), resulting in the state of FIG. In the state of FIG. 19, the corner 83 of the shutter 81 that holds the bent tip 66 a of the actuating rod 66 is separated, and therefore, as shown in FIG. The stop body 64 engages with the notch 74 of the operation lever 70 so that the operation lever 70 cannot rotate.
If the operation lever 70 cannot be rotated, the meshed rotor 77 cannot be rotated.

  Since the ear piece 102 is fitted in the fitting recess 92 and the rotor 77, the disc 100, and the arcuate plate 90 are in an integrated state, the shutter 81 shown in FIG. Is kept closed.

As shown in FIGS. 3, 4, 6, 13, and 20, a swing pin 111 is rotatably provided on the substrate 1 by a shaft 110.
As shown in FIG. 13, the swing pin 111 is divided into two portions 111a and 111b, and the tips are bent portions 111a ′ and 111b ′ that are bent vertically.

In the state where the shutter 81 in FIG. 20 is closed, the bent portion 111 b ′ of the swing pin 111 is near the tip end portion 94 of the arcuate plate 90.
Therefore, as will be described later, when the operating arm 23 rotates counterclockwise (in FIG. 6) after the tape is cut and the swing pin 111 is pushed as shown in FIG. Rotating to the center, the bent portion 111 b ′ presses the tip end portion 94 of the arcuate plate 90.

  Then, the arcuate plate 90 rotates clockwise (in FIG. 20) about the shaft 91 against the spring 93. Therefore, as shown in FIG. 100 ear pieces 102 are detached.

  The rotor 77 meshing with the operation lever 70 cannot rotate, and the disc 100 engaged with the protrusion 79 of the rotor 77 cannot be rotated by the spring 103, but the arcuate plate 90 is engaged with the disc 100. As shown in FIG. 21, the arcuate plate 90 attached to the shutter 81 and the shutter 81 by the spring 82 rotates clockwise, and the tip of the ear piece 102 is the end surface of the arcuate plate 90. It is in a state of being in pressure contact with 90 a by the urging force of the spring 93.

  When the shutter 81 is opened, the corner 83 presses the bent tip 66a of the actuating rod 66 to the left, so that the lever locking body 64 is disengaged from the notch 74 of the operation lever 70 and the biasing force of the spring 72 is applied. The operating lever 70 rotates counterclockwise about the shaft 71 and returns to the state shown in FIG.

  At the same time, the counterclockwise rotation of the operation lever 70 causes the rotor 77 (FIG. 16) meshing with the operation lever 70 to rotate clockwise, and the projecting piece 79 of the rotor 77 moves to the disc 100. When the tongue piece 101 is pressed, the disc 100 also rotates clockwise, and the ear piece 102 of the disc 100 slides along the end surface 90a of the arcuate plate 90 from the state of FIG. 19 is fitted into the mating recess 92 to return to the state of FIG.

As shown in FIGS. 1 and 13, a strip-like door 120 is rotatably attached to the inner upper end of the cover plate 2 by a shaft 121 and is urged by a spring 122 in a direction to close the entrance.
A detector 123 that detects rotation in the direction of being pushed into the inside of the door 120 is provided.

Next, the operation of this binding device will be described.
As shown in FIG. 22, for example, the free end of a tape A made of paper (A1 is an adhesive surface) is sandwiched between the flat plate 35 and the front end of the clamping operation plate 36 (this clamping will be described later). In a state where the operating arm 23 and the guide arm 28 are in a standby state at the position shown in FIG. 2, the user holds the handle 1d with his hand and presses the door 120 against the object B to be rotated, thereby turning the door 120 inward. When the object B is accommodated in the notch 31 and the operation lever 70 is rotated so as to pull the trigger with a finger, the shutter 81 is closed as shown in FIGS. 3 and 20 as described above. .

The rotation of the door 120 is detected by the detector 123, and the closing of the shutter 81 by the operation lever 70 is detected by the detector 80, and a detection signal is output to the control circuit 130.
The control circuit 130 operates by sending drive control signals to the motors 12 and 20.

The plate 10 moves in the lateral direction by driving the motor 12, and the gear 22 is rotated by driving the motor 20.
The amount of movement of the plate 10 is detected by the detection device 131, and the amount of rotation of the gear 22 is detected by the detection device 132 and sent to the control circuit 130.

  The control circuit 130 sends drive control signals to the motors 12 and 20 based on these two detection signals, and operates as follows.

  First, while moving the plate 10 to the right from the standby state of FIG. 2, the tips of the operating arm 23 and the guide arm 28 are rotated counterclockwise, and as shown in FIG. 4, and then rotated clockwise, as shown in FIG. 4, the object B to be bound is enclosed while the adhesive tape A is pulled, and the tapes A ′ and A ″ shown in FIG. 4 are enclosed. After bonding them together as shown in FIG. 5, as shown in FIGS. 5 and 8, the cutting plate 25 at the tip of the operating arm 23 is inserted between the flat plate 33 and the flat plate 34 to cut the tape A.

  At the time of this cutting, as described above, the clamping operation plate 36 (FIG. 8) is separated from the flat plate 35 and the free end of the tape A is released as shown in FIG.

After cutting, the operating arm 23 and the guide arm 28 rotate counterclockwise as shown in FIG. 6 to press the swing pin 111, and as described above, the shutter 81 is opened, and then the operation is performed. The lever 70 returns.
When the user moves the bundling device to the right (in FIG. 6) so as to take out the object B to be bound with the tape A, the door 120 is returned by the spring 122.

When the shutter 81 is opened, a detection signal is output from the detector 81 to the control circuit 130, and when the door 120 is restored, a detection signal is output from the detector 123 to the control circuit 130.
As a result, the control circuit 130 outputs a drive control signal to the motor 12 and the motor 20. Therefore, the operating arm 23 and the guide arm 28 rotate clockwise as shown in FIG. 7, and the end portion of the tape A from which the pushing plate 24 is cut is sandwiched between the flat plate 35 as shown in FIGS. While being pushed in between the operation plates 36, the holding operation plate 36 is restored as described above, and the end portion of the tape A that is pushed in is held between the flat plate 35 and the holding operation plate 36 as shown in FIG. 10.

  Next, the operating arm 23 and the guide arm 28 return to the standby state of FIG. Therefore, the end of the tape A changes from the state shown in FIG. 10 to the state shown in FIG.

  As described above, the bundling device of the embodiment sandwiches the free end of the tape A having adhesiveness, and the tip of the guide arm 28 for guiding the tape A is connected to the object B to be bound in a state where the tape A is extended. It is configured to move around and wrap around the object to be bundled B to bond the tapes together, then cut the end of the tape, and sandwich the end of the cut tape A. On the other hand, since the tape A having a non-sliding adhesive property is wound so as to surround the object to be bundled B while being stretched, the object to be bundled B can be firmly bound by a simple operation.
