Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic feeding device for a grain storage bag used in a grain storage device such as a threshing machine.

Conventionally, as a grain storage bag used in this type of grain storage device, the guide rod is inserted through the insertion holes provided on the left and right sides of the upper gate, and the bag is moved from the empty bag storage position to the lower position of the grain bag. What made it so is known.

In addition, as an automatic feeding device that automatically feeds out grain storage bags in the empty bag storage position one by one toward the lower position of the grain hopper, the grains are guided by an inclined guide rod, for example, as disclosed in Japanese Patent Publication No. 54-25873. A drop type of grain storage bag that utilizes the sliding of the grain storage bag itself, or
As in Japanese Patent No. 24876, a spiral blade type using horizontal spiral blades has been proposed.

However, in these conventional automatic dispensing devices using a sliding type or a spiral blade type, the upper side of the main body that is inserted through the guide rod is closed, and the opening and closing is closed with the filled grains provided at the upper side of the grain storage bag. The reality is that only special grain storage bags equipped with a tongue can be used, but this grain storage bag with an opening/closing tongue that closes with the filled grains does not allow the grains to be filled with the grains. Because the opening/closing tongue does not close completely,
Another drawback is that grain leaks from the opening/closing tongue, making it difficult to put into practical use an automatic feeding device that requires the use of a grain storage bag that is opened and closed.

[Discharge tube lifting device K]

Referring to FIGS. 3 and 5, a transmission shaft 21a is rotatably supported on a frame integrally fixed to the homper 1, and an arm 8 is fixed to a 685 portion of the transmission shaft 21a, and is integrally connected to the arm 8. It is designed to rotate. The elongated hole 8a provided in the arm 8 engages with a pin 61) fixed to the side of the discharge cylinder 6, and when the arm 8 rotates between 3 and 5, the discharge cylinder 6 is rotated.
The popper discharge port 1c is opened and closed as described above by performing two downward movements. That is, when the arm 8 is in the position a, the discharge tube 8 closes the discharge port IC, and when the arm 8 is in the position a, the discharge port ``C'' is opened. Arm 8 with the same configuration for the other paired hoppers
A pin 6b on the side of the discharge cylinder 6 is engaged with the elongated hole 8a'.This arm 8' is integrally fixed to the shaft 21a', and an arm 11 fixed to the shaft 21a' is further connected to the elongated hole 8a'.
is connected to an arm 11 fixed on the transmission IJJ shaft 2la side via a mouth/throat 12.

Therefore, the arm 8' is designed to move in synchronization with the arm 8 described above.

A gear 21 is fixed to the other end of the transmission shaft 21a.

This gear 21 is meshed with a pinion gear 20 driven by the motor 10 which is capable of forward and reverse rotation. Therefore, the discharge cylinder 6 is moved up and down by the power of the motor 10.

The motor 10 is stopped by turning on the arm 8' or the switch S8 when the discharge cylinder 6 reaches the raised position and closes the discharge port 1c. Further, when the motor 10 performs reverse rotation to lower the discharge tube 6 and open the discharge port IC, the arm 8' stops the reverse rotation by turning on the switch S5.

13.13' are the discharge holes I of the left and right hoppers 1, respectively.
This is a full detection sensor installed in the second part of the CJ. This sensor 1
3 and 13' are turned ON to detect when the grain storage bag 50 is full and the discharge port IC is blocked, and to issue a start signal to the motor 10 to raise the discharge tube 6.

FIG. 16 shows an electric circuit for raising the discharge cylinder 6.

In this electric circuit, 15 is a manual switch notch, which is provided outside the lower part of the hopper 1, as shown in FIG. 1.2. This manual switch 15 is connected to the full detection sensor 13.
, 13' is provided so that the discharge cylinder 6 can be manually raised 1 (a) at any time, and when the neutral sui-nochi 15 is turned on to the void s side, the relay 307 is activated. Switch, rotate motor 10 and discharge ↑
θj6 is lowered. Further, when turned on to the point lu side, the relay 308 is switched, the motor 10 is reversed, the discharge tube 6 is raised, and the discharge port IC is closed. Therefore, it is convenient when interrupting work.

In the electrical circuit diagram, 300, 301, and 302 are monostable multicircuits whose output becomes L for a short period of about 1 second in response to an input rising signal. Further, the switch S7 is turned from OFF to ON when the mobile device 84 of the bag opening device M, which will be described later, is in the raised position. When pulled up to cover the outside of the discharge port IC, OF
It turns ON from F.

In this way, the grain storage bag 50 is pulled up and the switch S
7 is turned ON, the discharge cylinder 6 is in the raised position in the closed state, so the switch S5 is OFF. Therefore, when the switch S7 is turned on, the signal S of the flip-flop 305 becomes I-1, and the signal Q of the flip-flop 305 becomes H. Therefore, the relay 307 is switched, and the motor 10 rotates in a direction to lower the discharge cylinder 6 and open the discharge port IC. By the monostable multi-circuit 300, flip-flop 3
050) S changes directly from L to "L", or) Maka month -
(2), and Q holds I-1.

When the discharge cylinder 6 is in the lower opening position (1), the switch S5 is turned on.
When the switch is turned on, R of the flip-flop 305 becomes L, S becomes L (therefore, Q is reset to I, and the motor 10 stops. As the discharge cylinder 6 descends, the switch S8
changes from ON to OFF, but the full detection sensor 13.1
Flip-flop 306 unless 3' is turned ON.
The output of remains L, and the motor IO does not start.

Next, when the grain storage bag 50 becomes full and the fullness detection sensor 13, 13° is turned ON, the flip-flop 30
Since S of 6 becomes L and switch S8 is OFF, R outputs I] and Q outputs H. - Therefore, the motor 10 reverses, the discharge tube 6 rises, and the discharge port 1c is closed. The switch S8 is turned on by this second rise of the discharge cylinder 6.
Therefore, the monostable multi-circuit 302 detects the rise of the input and outputs an instantaneous output. Therefore, the flip-flop 306 is reset with S set to H, R set to L, and Q set to L, so that the motor 10 stops.

[Bag feeding device L]

Referring to FIGS. 3 to 5, there is a pair of guide rails 34 at the bottom of each discharge port IC of the two left and right pumpers 1.
．． 34 is arranged, and this guide rail 34 is connected to the frame 3.
It is fixed to 6.

On the frame 36 side of this guide rail 34 is a power transmission shaft 3 that is pivotally supported across all of these guide rails 34.
3 is provided, and this transmission shaft 33'' second guide rail 34
A sprocket 3'2a is fixed at a position adjacent to each. A sprocket 32b is rotatably supported on the opposite side of each guide rail 34, and a check 735 is provided between each sprocket 1, 32b and the sprocket 32a.

On the other hand, the bracket 24 fixed on the opposite side of the frame 36
Several examples of motors 22 that can be rotated in forward and reverse directions are shown. The drive shaft 25 of this motor 22 drives a shaft 26, and further drives a shaft 26.
A chain 728 is interposed between the sprocket 27 fixed to the transmission shaft 33 and the sprocket 29 fixed to the transmission shaft 33, so that the power of the motor 22 is transmitted to the transmission shaft 33. Therefore, when the motor 10 rotates forward and backward, the check 735 reciprocates along the guide rail 34.

A bracket 44 is fitted onto the guide rail 34 via rollers 42 so as to be able to reciprocate along the guide rail 34. Further, a permanent magnet 45 is attached to the bracket 44, and the chain 735 is connected thereto. Therefore, when the chain 735 reciprocates as described above, the bracket 44 reciprocates together with the permanent magnet 45. That is, it constitutes a so-called moving magnet. At both ends of the reciprocating path of the moving magnet, a switch S3 is provided at a position corresponding to each bracket 44.
．． S4 is provided oppositely, and the switches S3 and S4 are connected to the bracket 7.
When 1.44 comes into contact, it is turned ON and the rotation of the motor 22 is stopped.

Further, at the innermost side of the empty bag storage section J, switches SL and 32 are provided to detect the presence or absence of empty bags, corresponding to the left and right grain storage bags 50 and 50, respectively. Each switch S
As shown in FIG. 5, L and S2 are provided at positions outside the moving path of the moving magnet, and the grain storage bags 50 are placed in the empty bag storage section J.
Only when the grain storage bag 50 is present, the pressing force of the moving magnet acts through the grain storage bag 50 and turns on. That is, when there is no grain storage bag 50 in the empty bag storage section J, the switches SL and S2 do not operate because the moving magnet does not come into contact with them.

Further, the guide rail 34 is configured to be able to swing between A and 8 around a shaft 26 that is pivotally supported by the body frame 30. A frame 37 is fixed to the guide frame 34 so as to cross the upper surface of the guide frame 34, and is interlocked with the above-mentioned discharge cylinder elevating device via the frame 37. That is, a bracket 38 is fixed to the upper surface of the frame 37, and this bracket 38 is connected to a link 39.
Transmission shaft 21 on the side to the discharge cylinder lifting device through ゜40.41
It is connected to an arm 9 fixed to a, and a guide rail 34 is interlocked therewith. The link 40 is rotatable upward and downward about the shaft 40a, and one end of the link 40 is engaged with the long hole of the link 39. Therefore, when the discharge tube 6 is in the raised position a, the links 39, 40, and 41 are in the a position in the figure, and the kite rail 34 is in the approximately horizontal state shown by A, but when the discharge tube 6 is in the lowered position, Then, links 39, 40.41
is at position b in the figure, and the guide rail 34 changes to a tilted state as shown by B.

Now, in the above-mentioned bag dispensing device, when the device is in a non-operating state, the moving magnet is on standby at the position shown by A in FIG. From this state, when the motor 22 is rotated by the bag feed signal, the permanent magnet 45 of the moving magnet moves toward the empty bag storage section J together with the bracket 44.

Due to this movement of the moving magnet, the permanent magnet 45 attracts the magnetic body 52 of the grain storage bag 50 located on the outermost side and continues to press it. By this pressing, a plurality of grain storage bags 50
are pressed one after another to turn on the switches Sl and S2, and the presence of the grain storage bag 50 is known (ε. Both 31 and 32 are turned on.
When N is selected, the rotation of the motor 22 is temporarily stopped and then immediately reversed, and the permanent magnet 45 of the moving magnet moves toward the lower part of the discharge port 1c together with the grain storage bag 50 that has been attracted. Then, when the blow-note 44 comes into contact with the switch S4 and turns it on, the motor 22 stops. As a result, the pair of left and right grain storage bags 50.50 are opened at the discharge ports 1c and 1, respectively.
It is placed below c.

When the grain storage bag 50 is placed below the discharge port IC, the grain storage bag 50 is opened wide by a bag opening device M, the details of which will be described later, and is pulled up to a device that covers the outside of the discharge port IC. Next, the motor 10 rotates and the arms 8, 8
' lowers the discharge cylinders 6, 6, and inserts the closed end 6a of the discharge port 6 into the grain storage bag 50. In conjunction with this lowering of the discharge cylinder 6, the guide rail 34 is moved from the horizontal state A to the inclined state B.
rise to the state. As the guide rail 34 of the grain storage bag 50 rises, the permanent magnet 45 and the magnetic body 52 of the grain storage bag 50
Since a shearing force along the plane direction acts between the permanent magnet 45 and the magnetic body 52, the permanent magnet 45 easily separates from the magnetic body 52.

In other words, the attraction force of the magnet is large in the direction perpendicular to the surface of the magnetic material 52, but is small in the direction along the surface. If you move it in the direction along it, you can easily detach it.

When the guide rail 34 is raised and the discharge tube 6 is lowered to turn on the switch S5, the motor 10 is stopped. After the motor 10 stops, the motor 22 rotates by a certain angle, moves the moving magnet to the position shown in the figure, and stops.

When the grain storage bag 50 is full, the fullness detection sensor 13.1
3' are both turned ON, the motor 10 rotates and the discharge cylinder 6 rises to close the discharge port IC.

With this closure, the guide rail 34 returns to the horizontal state, but the moving magnet remains in position A and waits for the next collection operation so as not to interfere with the removal of the full bag.

As described above, according to the bag dispensing device, the task of setting the empty grain storage bag 50 is simple because it is only necessary to insert and push the empty grain storage bag 50 through the guide rod 4. Moreover, since the magnetic material 54 is provided on the side of the grain storage bag 50, the grain storage bags 50 do not attract each other, and the permanent magnet 45 of the moving magnet reliably attracts and feeds out the grains one by one. I can do it. In other words, if a permanent magnet was attached to the grain storage bag 50 side, the plurality of grain storage bags 50 would be mutually removed due to mutual attraction of the magnets), 1
It becomes impossible to reliably pay out one sheet at a time.

In the above device, when the moving magnet force (reaching the lower part of the discharge port IC and separating from the magnetic body 52 force 1 of the grain storage bag 50) is applied not in the perpendicular direction to the surface G of the magnetic body 52, but in the plane. Since it moves upward along the direction and rises, it can easily escape from G with an extremely small upward force.For this reason,
Even if permanent saltpeter, which is stronger than LL, is used as the moving magnet, the drive device for raising the moving magnet upward together with the force idle rail 34 and the like can be made smaller and lighter.

In addition, the load on the drive unit is small, and the device can be made inexpensive.

In the above embodiment, the permanent magnet 45 is used as the moving magnet, but this magnet may be replaced by the electromagnetic magnet G.

[Bag opening device M]

Referring to FIGS. 6 to 11, this is a guide plate fixed to the lower side surface of Maho Tsunomar 1 No. 93. With respect to this guide plate 93, a movable plate 84 is slidably guided in the vertical direction via an inner surface (j, +J4 x 1:7-ra 97) so that it can reciprocate. 8° is a motor that can rotate in forward and reverse directions, and an arm 80a is fixed to the drive shaft of this motor 8o so as to swing back and forth from side to side.A pin provided at the tip of this arm 80a connects the arm 82.
This arm 82 is integrally fixed to a shaft 81 rotatably supported on the frame. An arm 83 is fixed to the shaft 81 and rotates together with the shaft 81. A long groove 8 provided at the tip of this arm 83
3a is engaged with a pin 84a fixed to the outer surface of the movable plate 84. Therefore, the reciprocating rotation of the motor 8 degrees causes the movable plate 84 to reciprocate up and down.

S6 is a switch provided at the lower end of the guide plate 93, and is a switch provided on the lower end of the guide plate 93.
When it comes to the lowered position, it comes into contact and turns on, motor 80
stop rotating. Further, a switch s7 provided at the end of the guide plate 93 is brought into contact with the switch s7 and turned ON when the movable plate 84 reaches the second raised position, thereby stopping the motor 80 from rotating in the opposite direction.

Links 86 are provided at both ends of the moving plate 840. ．． 87 is rotatably supported. A plate 88 is pivotally supported on the other end side of the links 86 and 87, forming a parallel link as a whole. A permanent magnet 9o is fixed to the plate 88 via a J plate 89.

On the other hand, arms 91 and 91 are fixed to the pivoting sides of the links 86 and 86 disposed on both sides relative to the movable plate 84, and the arms 91 and 91 are connected to each other by a spring 9.
It is connected by 2. For this reason, link 86.87
is caught by the elastic force of the spring 92, and always maintains a wide-angle posture with the tip side (the side where the plate 88 is attached) spread outward, as shown by the solid line.

Further, a cam 95 is fixed to the upper end side of the link 86. When the cam 95 descends from the raised position d to the lowered position C together with the movable plate 84, it comes into contact with a stopper 94 fixed to the lower side surface of the guide plate 93, and the ends of the left and right links 86 and 87 as shown by broken lines. The permanent magnet 9o gradually moves toward the center, and the grain storage bag 5o is brought into contact with and attracted to the magnetic bodies 54 on both sides. Next, when the movable plate 84 rises again in the above-mentioned suction state due to the reverse rotation of the motor 8o, the cam 95 separates from the stopper 94, opens the left and right links 86 and 87 outward, and widens the opening of the grain storage bag 50. Raise it from above. Just wanted to say, grain storage bag 50
For example, the upper edge of the bag, which was lower than the lower end of the outlet 1c as shown in state C, is changed to the state D where the upper edge of the bag covers the outside of the outlet 1c. At the same time, the lower part of the bag, which had been bent so as to be bent on the floor 6o as shown in C, is brought into a state where it is not bent on the floor 6o as shown in D.

Therefore, according to the bag opening device M described above, the grain storage bag 5° is attracted to the permanent magnet 90 at the tip of the bag opening tool at the lower part of the popper outlet 1c via the magnetic body 54 on the side surface. Since the upper opening is widened, the outside of the discharge port 1c can be covered, and the discharge tube 6 can be inserted reliably and smoothly. However, the grain storage bag 50 is pulled upward by the bag-opening tool, and the binding gB is kept from bending or folding on the floor 6o, so that the grains are evenly distributed all the way to the bottom of the bag. It can be filled evenly. In addition, since the grain storage bag 50 is held using a magnet, when the grain storage bag 50 is filled with enough grains to fill the bag,
Since the grain storage bag 50 is naturally detached from the permanent magnet 90 due to the weight of the grains, the detachment operation is not necessary, simplifying the work, and preventing damage to the bag.

Note that the permanent magnet 90 used in the above embodiment may be replaced with an electromagnet.

[Full bag drawer N]

Referring to FIGS. 1 and 3, as described above, the kite rod 4 for suspending the grain storage bag 50 is constructed by slidably fitting the cylinder rod 4a and the rod rod 4b. floor 6
At the front end of 0, a support rod 61 has a lower end connected to a plate spring 6.
The upper end of the support rod 61 supports the end of the rod 4b. A frame 63 is fixed to the upper end of the support rod 61, and a retaining plate spring 64 provided inside the frame 63 removably grips the end of the rod 4b by its elastic force.

Reference numeral 67 is a cover that covers the upper surface of the floor 60 in the empty bag storage section J, and prevents the flexible portion of the lower part of the empty grain storage bag 50 from directly interfering with the upper surface of the floor 60 and damaging it. Further, numeral 68 denotes a partition plate provided at the boundary position of the empty bag storage section J to prevent interference between the empty bags and the full bags on the front side, and to prevent them from shifting together.

A hydraulic cylinder 5) is installed in the frame below the floor 60, and a piston rod 66 of this hydraulic cylinder 65 is installed.
The front end of the floor 60 is fixed to the back of the apron which is bent. Therefore, by the operation of the hydraulic cylinder 5, the floor 60 located at the position indicated by the solid line in the figure moves forward together with the rod 4b of the kite rod 4 to the forward position (direction perpendicular to the direction of movement of the combine harvester) shown by the broken line. You can return to your original position. S9 and SIO are each switches. Switch S9 is activated when the floor 60 moves forward and the rear end is removed from switch S9.
Close the selector valve of the cylinder to stop the forward movement of the screw rod 66. Also switch S
When the floor 60 moves backward and its rear end contacts the switch S10, the IO closes the hydraulic oil switching valve for the cylinder 65 and stops the piston rod 66 from moving backward.

With the above-mentioned configuration, when the grain storage bag 50 becomes full, this device can operate the hydraulic cylinder 65 to pull out the full bag forward, leaving the full bag in the drawn-out state. The next empty bag is placed at the outlet I by the bag feeding device.
It can be fed out below C and immediately move on to the next grain storage operation. Therefore, since it is possible to work with full bags in front and back side-by-side, and thereby to save time, the empty bag storage section J
The space can be made larger by the amount that the guide rod 4 is incremented by i;.

In short, the automatic feeding device for grain storage bags according to the present invention is arranged in a substantially horizontal direction in which the insertion holes of the main body provided on the left and right sides of the upper opening are extended from the empty bag storage position to the lower position of the grain popper. A grain storage bag is inserted through a guide rod and stored in an empty bag storage position of the guide rod, and a magnetic body provided at the upper opening of the grain storage bag is moved along the guide rod to deliver the bag. A magnet provided on the device side attracts the empty bag storing position of the bag feeding device to prevent the grain storage bag from being drawn out to a position below the grain popper due to movement of the bag feeding device, and
The bag dispensing device is moved to a position below the grain popper of the grain storage bag that has been moved, and the magnet on the bag dispensing device side is vertically separated from the magnetic body on the grain storage bag side. A grain storage bag is inserted through the insertion holes provided on the left and right sides of the opening into the left and right guide rods in a substantially horizontal direction, and the empty bag is stored along the magnetic material or guide rods provided at the upper opening of the grain storage bag. Although it is possible to feed the grains to the lower position of the grain popper by utilizing the parallel state of adsorption by the magnet on the side of the bag feeding device that has moved to the position, the grain storage bag that has been moved to the lower part of the grain popper can be fed out. By moving the bag feeding device at this position, the magnet on the bag feeding device side is vertically separated from the magnetic body on the grain storage bag side supported by the guide rod, and the grain storage bag is moved below the grain hopper. can be stopped.
