Description

Detailed Description of the Invention [Industrial Field of Application] The present invention provides an endless rotation band that moves in parallel directions with bag support rods, and is capable of filling grain bags suspended and supported by the bag support rods. The present invention relates to a bag fastener operating structure for a grain bagging device, in which the endless rotating band is provided with a fastener operating part for closing the mouth fastener.

[Conventional technology]

The grain bagging device described above is configured to close the filling port fastener by the rotational force of the endless rotation band.

Conventionally, in this type of bagging device, when the slider of the filling port fastener closes and reaches the stroke end, the fastener operating part reaches the endless rotating band wrapping ring body as the endless rotating band is driven. Due to the rotation of the endless rotation band along the wheel, it was configured to move upwardly away from the grain bag and away from the slider. In other words,
The endless rotating band is driven in only one rotation direction, and when the slider reaches the closing stroke end, the fastener operation part is raised from the slider push transfer level up to that point and separated from the slider, thereby closing the endless rotating band. It was possible to separate it from Fuasner, who had become an adult.

[Problem to be solved by the invention]

Conventionally, it has been necessary to configure the slider so that the slider closes and slides simply by abutting the fastener operating section on the slider from the upper side in the transfer direction, so when the fastener is closed, the endless rotation band vibrates and the fastener is operated. It sometimes came off from the section, causing a closing error.

An object of the present invention is to ensure a reliable closing operation.

[Means for Solving the Problems] The characteristic configuration of the present invention is that, in the bag fastener operating structure of the grain bagging device described above, an endless rotating band is attached so as to be freely driven in the forward and reverse directions, and the endless rotating band is The fastener operation part engages with the slider of the filling port fastener by rotational driving and slides the slider to the closing side, and the fastener operation part separates from the slider by reverse driving of the endless rotating band. Further, in the engaged state, the fastener operating section is formed in a state that prevents the fastener operating section from separating upward from the slider, and an engagement means for the fastener operating section and the slider is provided. . The functions and effects thereof are as follows.

[Effect]

Even if the engaging means is used to interlock the endless rotating band and the fastener so that the upward movement of the fastener operation part from the slider is suppressed during the fastener closing operation, the endless rotating band will not move when the fastener is closed. By driving the fastener in the reverse direction, the fastener operation part is detached from the slider, and the endless rotating band can be separated from the fastener in the closed state.

〔Effect of the invention〕

By switching the detachment of the fastener operation part from the slider from normal rotation to reverse rotation of the endless rotation band, when the fastener is closed, the fastener operation part is engaged with the slider by the engagement means to suppress upward separation. This makes it possible to perform a closing operation while making it difficult for a closing error to occur due to the upward movement of the fastener operating section from the slider.

〔Example〕

Next, examples will be shown.

As shown in FIGS. 1 and 2, a reaping pre-treatment device 1 that causes and reaps planted grain culms as the aircraft travels and conveys the reaped grain culms to the rear of the aircraft is connected to a crawler type traveling device 2, a driving section 3.

Bag 9 on both support rods 1
0, 10 and conveys the second endless rotation chain 19 while sliding on the rollers 18 juxtaposed on the mounting surface of the mounting table 17,
A control mechanism (not shown) is provided on one side of the traveling machine and automatically operates both the devices 11, 12 and the chains 16, 19, and the machine is equipped with a control mechanism (not shown) for bagging threshed grains and filling filled bags. The transportation and storage of the images onto the mounting table 17 is automatically performed as follows.

That is, a plurality of grain bags 9 are attached to the storage section with their fasteners 15 open, and
A grain bag 9 is manually attached to the tips of both support rods 10, 10, a boot 13 is manually inserted into the bag 9, and a shutter 14 is manually opened to start the work. When the bag 9 becomes full and the pressure-sensitive sensor 20 detects this, the first chain 16 first closes the shutter, lifts the boot, and closes the fastener in sequence, and then,
The second chain 19 removes the filled bag,
A take-out device 11 takes out an empty bag 9 and supports both support rods 1.
0 and 10 are attached to the tip, and the bag opening device 12 is activated. Then, when the bag 9 is opened, the first chain 16 sequentially performs the boot insertion operation and the shutter release operation to resume filling, and thereafter each operation is performed sequentially in the same manner as after the start of the work.

The bag removal device 11 is configured by:
As shown in FIG. 4, the bag support rods 10, 10 are rotatably attached to their support bosses 21, and
A first threaded portion 22 and a second threaded portion 23 act on eyelets 9a provided at both lateral ends of the grain bag 9 to form a bag support rod insertion hole, thereby locking and transferring the bag 9. A pair of spiral bodies each formed separately are arranged in parallel in the support rod axis direction with the first threaded portion 22 located closer to the support rod base end than the second threaded portion 23,
In addition, in a state in which the feeding directions of both threaded parts 22 and 23 are opposite to each other, and furthermore, in a state in which both threaded parts 22 and 23 are connected by the support rod 10 so as to rotate together, the support rods 10 and 10 are An electric motor M is attached to the distal end side so as to be integrally rotatable, and is an example of a mechanism for driving both the threaded portions 22 and 23 in forward and reverse directions.
The output rotation arm 2 is engaged with the support rod rotation operation arm 10a provided at the base end of the support rod 10.
Support rods 10, 1 through a speed reduction mechanism 25 having 4
0 respectively, and is also linked to the control mechanism so that it can be rotated and stopped by it, so that it operates as follows.

That is, as the second chain 19 takes out the filled bag 9 from the tip of the support rod, both motors M, M move in a direction that allows the first threaded portion 22 to feed the bag toward the tip of the support rod. As the first screw portion 22 rotates and changes from the state shown in FIG. 5A to the state shown in FIG. As it rotates further, the take-out bag 9 is transferred to the tip end side of the support rod. When the transfer bag 9 reaches the starting end of the second threaded part 23 as shown in FIG. Only the bag 9 transferred by the first threaded part 22 is rotated in the direction in which it is rotated, and the first threaded part 22 that reverses the movement of the bag 9 remaining in the storage part from coming to the tip end of the support rod. is continuously transferred to the tip side of the support rod by both second threaded portions 23, 23. When the transfer bag 9 reaches the tip of the support rod as shown in FIG. 5D, both motors M, M are stopped and the bag removal is completed. The timing of switching the rotational direction of the motor M when the grain bag 9 reaches the starting end of the second threaded part 23 and the timing of stopping the motor when the grain bag 9 reaches the tip of the support rod 10 It is determined based on the information from the screw rotation speed detection counter linked to the thread rotation speed detection counter and the setting device for the rotation speed at which the screw portion should be operated, or when the bag is at the starting end of the second screw portion or the tip of the support rod. The decision is made based on information from the switch that detects that the target has been reached.

Further, in configuring the bag opening device 12, as shown in FIGS. 3 and 4, an opening operation plate 26 that acts on the periphery of the bag support rod insertion hole of the grain bag 9 is connected to the bag support rod. 10 and 10 so as to be integrally rotatable, and when the opening operation is performed, each of the opening operation plates 26 is moved horizontally of the grain bag 9 by the rotational force of the motor M transmitted through the bag support rod 10. It is configured to be driven to swing outward. That is, a relaxing force is applied to the filling opening edges of the bag 9 so that both lateral ends approach each other, and the pair of opposing filling opening edges are curved and deformed in the direction of separating from each other to open. It's like this.

Further, the first chain 16 is shown in FIGS. 3 and 4.

The configuration is such that it is possible to unlink the . At the start of work, each of the operating arms 28, 29, and 30 is in the first standby position where the shutter operating arm 28 and the first limit switch _SW1 for position detection are in contact with each other, and the grain bag 9 is full. Accordingly, the first chain 16 is rotated forward in the direction of arrow A, and the shutter operating arm 28 first presses the swingable shutter opening/closing device 31, which is in the open position (OP), to the closed position (CL) to open the shutter 14. Then, the boot operation arm 29 presses the swinging boot lifter 32, which is in the lowered position (DN), to the raised position (UP) to pull out the boot 13, and then operates the fastener. The arm 30 locks and moves the slider 15A toward the rear of the body to close the fastener 15. When the fastener closing is completed and the fastener operating arm 30 contacts the second limit switch _SW2 that detects the end of its stroke, the chain 16 is reversely driven in the direction of arrow B, and the fastener operating arm 30 is disengaged from the slider 15A. When the shutter operating arm 28 comes into contact with the third limit switch SW ₃ for position detection, the chain drive is stopped and each operating arm 28, 29, 30
is on standby at the second standby position where the shutter operating arm 28 and the third limit switch _SW3 are in contact. Then, when the empty bag 9 is attached to the tip of the support rod, the chain 16 is driven in the direction of arrow B.
The boot operating arm 29 presses the boot lifter 32 in the raised position (UP) to the lowered position (DN) to insert the boot 13, and the shutter operating arm 28 opens and closes the shutter in the closed position (CL). When the tool 31 is pressed to the open position (OP) and each operating arm 28, 29, 30 reaches the first standby position, the chain drive is stopped and the bag waits at that position until it is full. It's like this.

The coil spring 33 shown in FIGS. 4 and 5 is for urging the bag 9 stored on the base end side of the bag support rod 10 toward the first threaded portion 22. The leaf spring 34 shown in FIG. 4 is used to prevent the storage bag from lifting up from the support rod 10 to prevent the first threaded portion 22 from being removed incorrectly. The leaf spring 35 shown in FIG. 3 moves the boot lifting tool 32 to a position where the boot operating arm 29 can pass forward or backward after pressing the boot lifting tool 32.
The leaf spring 36 maintains the boot lifting device 32 swinging back into the path of the boot operating arm 29 after passing the boot operating arm 29 while allowing the shutter operating arm 28 to be displaced. The shutter operating arm 2 is moved while allowing the shutter opening/closing tool 31 to be displaced to a position where it can pass forward or backward after pressing the shutter opening/closing tool 31.
8, the shutter opening/closing tool 31 is kept swinging back into the passage of the shutter operating arm 28.

The bag removal device described above can be applied not only to combine harvesters but also to stationary grain bagging devices.
