Next, referring to FIG. 1 to FIG.
Will be described. The tape feeding section 5 is connected to the binding section 4.
A constant braking force having a conventional configuration is applied to a delivery shaft 51 which is provided with left and right delivery wheels 50 for delivering and feeding the tape 2 inwardly at the upper portions of both side frames 11 corresponding to the left and right binding positions. Each of the feeding wheels 5 is mounted and supported via a friction support mechanism for freely feeding and rotating the feeding wheel 50 so that the feeding wheel 5 can be rotated.
The tape 2 to be inserted and supported at 0 can be smoothly fed out by an amount required for the binding operation.
Reference numeral 52 denotes a guide roller which rolls and guides the lower side (front side) of the tape 2 at the front side of the feeding wheel 50, and the guide roller 52 stretches the tape 2 with a proper downward inclination between the gripper 40, It is intended to smoothly guide the pressing contact by the pressing portion 42.

In the illustrated example, the tape feeding section 5
By installing a feeding assist mechanism 5a, which will be described later, on the feeding wheel 50 on the neck side of asparagus, it is possible to loosen the winding and binding of the neck side of asparagus. The tape 2 to be inserted and supported on the feeding wheel 50 has an adhesive surface coated with an adhesive on one side of a film tape having a width of about 10 mm, and the adhesive surface is set inside.
A commercially available wound tape is used, in which the tape 2 is wound in multiple layers around a core material that can be inserted into the core material.

Next, the slide table 8 will be described with reference to FIG. The slide base 8 is formed in a flat plate shape having substantially the same width as the horizontal frame 12 below the tape feeding section 5, and slide sections 80 are provided on both side ends thereof. And slide table 8
The slide portions 80 on both sides inside the side frames 11,
A crank arm 83 provided on the motor shaft 82 of the drive motor 8M supports the slide base 8 in a vertically movable manner by being inserted into and engaged with a guide rail 81 provided along the inclination direction. When the drive motor 8M performs one rotation during the binding operation of the binding unit 4, the slide stand 8 is moved from the binding standby posture at the solid line position shown in FIG. 3B to the binding posture shown by the dotted line via the crank arm 83. In addition to the lowering to the position, after the completion of the binding operation, the returning operation to the original binding standby posture can be performed. Reference numeral 8S denotes a limit switch that detects a return operation of the slide base 8 and stops positioning at a predetermined position.

Further, the slide base 8 which moves up and down in the rear inclined posture by the above-mentioned structure has a cutter 41 and a pressing part 42 attached and fixed up and down at a front part thereof, and a feeding assist mechanism 5a at a rear part thereof. It is mounted and supported integrally. As shown in FIG. 3, the feeding assist mechanism 5a is
The extension piece 58 having a downwardly engaging portion 57 formed at the distal end thereof is swingably and rotatably mounted on a holder 55 standing upright from a mounting shaft 56 via a mounting shaft 56, and a spring 59 a provided on an adjusting screw 59. A downward biasing force is applied so as to be adjustable, and the lower limit position of the feeding piece 58 is adjusted by a stopper bolt 59b. The engaging portion 57 is formed on an uneven surface, and is brought into contact with and joined to an engaging wheel 50a formed of a plastic material integrally with the feeding wheel 50 at a position where the holder 55 contacts the stopper bolt 59a. Have to be able to.

With this configuration, when the slide base 8 descends as shown by the dotted line, the engaging portion 57
a from the rear side, the engaging wheel 50a engages with the peripheral surface of the engaging wheel 50a and attempts to rotate the engaging wheel 50a in the winding direction.
No. 0a is non-rotatable because the tape 2 is stretched by the grip portion 40, so that the engaging portion 57 retracts the feeding piece 58 upward against the spring 59a.
The vehicle travels over the engaging wheel 50a while slipping over the engaging wheel 50a and moving forward. When the slide base 8 returns to the ascending position, the engaging portion 57 is engaged with the engaging wheel 50a again. In this case, since the engaging wheel 50a is in the extending direction, the tension drag of the tape 2 does not act. The joint wheel 50a is rotated in the feeding direction by a predetermined engagement amount, whereby the tape 2 is fed by the predetermined engagement amount, and the tape 2 is moved between the grip portion 40 of the binding portion 4 and the feeding wheel 50. Stretch with 2 loosened.

Accordingly, since the tape 2 on the neck side is always stretched in the binding standby posture in a loosened state, the asparagus is supplied and conveyed to the tying part 4 by the conveying part 3, and the neck of the asparagus is taped. When pressing the tape 2 into the binding standby posture, the tape 2 has a slack,
The neck of the asparagus is not broken by the pressure contact of the tape 2. Further, in this state, the tape 2 is gripped by the operation of the pressing portion 42 accompanying the lowering of the slide table 8.
Pressing and sticking to the tape 2 on the 0 side, the asparagus can be loosely bound without strongly tightening the neck side of the asparagus, and the asparagus is in a state of being easily broken with a large amount of moisture immediately after harvesting. Even in this case, there is an advantage that the binding operation in which the neck portion is prevented from being broken can be performed efficiently and smoothly.

Next, the discharge path 6 will be described with reference to FIGS. The illustrated discharge path 6 includes a plurality of downwardly inclined discharge transfer guides 60 positioned between the support receiving member 71 and the gripping reception member 9 in the binding posture of the transport unit 3, and a base of the discharge transfer guide 60. A discharge guide 61 formed of a flat plate extending downward and rearward of the machine base 10, a discharge sensor 62 and the like protruding from below the discharge transfer guide 60 along the start end of the discharge guide 61, and the like. Thus, a series of discharge paths 6 for slidingly discharging asparagus from the lower part of the binding part 4 toward the rear of the machine base 10 have a simple and inexpensive structure.

That is, in the binding posture of asparagus, the transport unit 3 which has rotated half a turn from the supply unit 1a is in a substantially horizontal state,
Since the gripping receiving device 9 and the receiving device 73 are open downward, when the tied tape 2 is cut, the tied asparagus is directly dropped on the discharge and transfer guide 60,
The sheet passes smoothly over the discharge sensor 62 without being accompanied by a large drop impact and the like, and is guided by the discharge guide 61 so as to be neatly accommodated in a container (not shown) installed at the rear of the body frame 13. Therefore, it is possible to efficiently discharge asparagus while preventing damage to asparagus at the time of discharging. In addition, since the asparagus gas is slid and discharged by the discharge transfer guide 60 and the discharge guide 61, the discharge path 6 does not require a special discharge drive mechanism such as a discharge belt from the position where the transport unit 3 is substantially horizontal. In addition to being able to be manufactured with a low-cost configuration, the discharge path 6 can be compactly integrated in the space formed below the tape feeding section 5 installed in the backward tilted posture without increasing the size of the machine. There are advantages such as installation configuration.

The discharge sensor 62 is installed substantially at the middle between the discharge transfer guide 60 and the discharge guide 61, and when the asparagus passes, it is pushed downward from the solid line state in the illustrated example by its weight. The circuit configuration is such that the operation of the entire apparatus is turned on (operated) in the solid line state. Therefore, according to this, for example, when asparagus is caught and stopped in the middle of the discharge path 6, or when the removal of asparagus on the discharge guide 61 is forgotten and the asparagus stagnates on the discharge guide 61 Has a discharge sensor 6
2 turns off the operation of the apparatus, so that there is an advantage that a trouble caused by the binding operation when asparagus is clogged in the discharge path 6 can be accurately prevented with a simple configuration. is there.

Next, the asparagus bundling operation by the bundling apparatus 1 configured as described above will be described. First,
When the asparagus gripped by a handful is inserted into the supply unit 1a of the transport unit 3 in the binding standby posture in a substantially horizontal state shown in FIG. 1 and the asparagus is received, the receiver 73 and the movable claw 95 are opened. When it is supported by the fixed claw 91, it is supported by the weighing receiver 1c and measured by the weighing unit 1b, and when the weight is appropriate, the drive motors 7M and 8M enter an operation standby state. When the supply unit sensor 1S detects that the asparagus is left in the transporting unit 3 and the hand is pulled out, the transporting unit 3 rotates about 180 ° about the rotation shaft 70 halfway in the automatic operation state to remove asparagus. Binding unit 4
To the side.

At this time, the conveying section 3 closes the movable pawl 95 by being brought into contact with the closing cam surface 9 b of the cam guide 97 by the urging force of the spring 98 to close the asparagus with the fixed pawl 91.
Since the asparagus is accurately grasped without being crushed by the spring urging force, and the asparagus is stably supported by the support receiving members 71, 71,.. Even if the rotating speed of the transport unit 3 is increased and the transport unit 3 is rotated half a turn, asparagus can be accurately transported and transferred to the binding unit 4 without leaking from the transport unit 3 and without disturbing the transport. Can be in contact with the tape 2. Next, the movable claw 95 is opened against the spring 98 by the opening motion cam surface 9c, and is pressed against the tape 2 in the binding standby posture by the fixed claw 91 and the holder 73 while releasing the asparagus gripping.

As a result, the asparagus conveyed as shown in FIG. 10 is properly received on the two tapes 2 at the neck side and the base side in a half-wrapped manner, and a good bundling operation is performed. Can be performed in a union-disruption start posture. When the slide base 8 moves down in the binding start posture in which asparagus is held between the gripping receiver 9 and the tape 2 in a sandwiching manner, the pressing portion 42 of the binding portion 4 causes the outer surface of the tape 2 to move. When pressed, the tape 2 is wrapped around the entire circumference of asparagus and pressed and adhered to the tape 2 side fastened by the gripping portion 40 to bind it.
The binding tape 2 is cut by the cutter 41 and
The end of the tape 2 cut in the above step is fixed, and then the slide table 8
As a result, the bound asparagus is accurately discharged to the lower discharge path 6 side.

At this time, in the tape feeding section 5 provided with the feeding auxiliary mechanism 5a, the binding section 4 stretches the tape 2 on the root side in a substantially tension state between the gripping section 40 and the feeding wheel 50, Since the tape 2 on the neck side is stretched in a loosened state, the relatively rigid base portion side is firmly wrapped with the tape 2 halfway, and the soft and easily breakable neck side is loosened halfway. It is wrapped, and from this state, both parts are pushed by the pressing part 42 of the tying part 4 to be tied. Therefore, even asparagus with a large amount of water or asparagus collected in the morning, it may be broken or crushed. It is possible to properly tie without causing any troubles such as defects and to efficiently perform good tying without lowering the quality.

In the binding posture of asparagus, the transport unit 3 which has rotated half a turn from the supply unit 1a is in a substantially horizontal posture,
Since the grip receiving device 9 and the receiving device 73 are open downward,
When the tied tape 2 is cut, the tied asparagus is smoothly transferred as it is onto the discharge and transfer guide 60, passes through the discharge sensor 62 without a large drop impact, etc., and is transferred to the discharge guide 61. Guided to the fuselage frame 1
3. Since the exhaust gas is discharged rearward, the asparagus can be efficiently exhausted while preventing damage to asparagus at the time of exhaustion. Further, since the discharge path 6 is configured to slide and discharge asparagus by the discharge transfer guide 60 and the discharge guide 61 from a position where the transport unit 3 is substantially horizontal, a special drive mechanism such as a discharge belt is not required. The tape feeding section 5 which can be manufactured at a low cost and is installed in a backward inclined posture.
There is an advantage that the airframe can be compactly installed and configured without increasing the size of the body in a space formed below the spacecraft. And since the tape feeding section 5 can be installed at a lower position than the conventional one, the bundling device 1 which is easy to use and easy to use for maintenance work such as replenishment of the tape 2 and the like.
Can be provided.

In this embodiment, the tape winding and sticking type bundling device 1 for binding asparagus with the tape 2 having a single-sided adhesive has been described. Alternatively, a tying device of a string tie type may be used with a twisted string made of plastic fibers or the like. Further, the material to be bound by the binding device 1 is not limited to asparagus.
