2. Description of the Related Art Pail packs come in various sizes, but usually, for example, can weights of 200 kg and 300 k.
Two types of g are used. And each can diameter is 520m
m and 670 mm, the height is 825 mm and 770 m
m and the height when loaded on a pallet is 945 m
m and 895 mm. These pail packs are shown in Figure 1.
As shown in (2), two or more having the same size are loaded on a pallet, and each pail pack is bound together with the same pallet by a binding band and carried out. The bundling at this time is performed by vertical bundling along the vertical plane and horizontal bundling along the horizontal plane as shown in FIG.

Since these bindings are heavy and bulky, conventionally, the bindings have been mainly done manually by using a binding tool, but in recent years, various labor-savings have been realized. Proposals have been made, and automatic binding machines are being put to practical use.

[0004]

However, in the vertical tying by such a conventional automatic tying machine, the tying band is vertically wound around each pail pack as described above. At this time, the vertical binding band is inserted through the hollow part formed between the spacers of the pallet to fasten and fix the pail pack and the pallet all at once in the vertical plane, but the vertical binding band is wound along the vertical plane. Fixed with
Depending on the size of the pail pack or the insertion position of the binding band to the hollow part of the pallet, the position where the band is inserted through the hollow part of the pallet and the fork insertion position of the pallet transporting forklift are matched, and the band is damaged. This causes the load to collapse.

On the other hand, one handle is attached to each of both side surfaces of the upper part of the pail pack, but in order to prevent lateral displacement of the vertical binding band, it is preferable to insert the vertical binding band through the ring of the handle. Although the operation can be performed manually, the vertical binding band cannot be inserted through the ring of the handle in the conventional automatic binding machine, and it is impossible to surely prevent the vertical binding band from being laterally displaced. there were.

The present invention has been made for the purpose of solving the problems of the conventional automatic binding machine as described above. Specifically, the binding band is damaged by the fork of a forklift for pallet transportation. It is possible to insert a vertical band into the handle of the pail pack at the same time, and a powerful automatic binding method that does not cause a load collapse that can continuously and automatically perform a series of binding work including horizontal binding. The purpose is to provide the binding machine.

[0007]

SUMMARY OF THE INVENTION The above object is to bind a pallet loaded with two or more pail packs, which is a main component of the present invention, together with the pail packs continuously and automatically by a vertical binding device and a horizontal binding device. A method for automatically bundling a pail pack, characterized in that the vertical bundling is performed by inserting a vertical bundling band through the handle of each pail pack and bundling it obliquely at a required angle to circulate the substantially central bottom of the pallet. Achieved by

Specifically, the pallet loaded with the pail pack is transferred to the vertical bundling position by the supply means, the pail pack is positioned with the pallet by the centering means before the transfer to the vertical bundling position, and during the transfer. Including rotating the handle in the hanging state by the handle upright means to the upright state, and inserting the binding band through the handle in the upright state by the band guide means and circling the pallet through substantially the center of the bottom portion. Further, the bundling band is guided by the band guide means arranged at the vertical bundling position at a required inclination angle with respect to the vertical binding position, and the pail pack and the pail pack in an upright state along the inclined surface. Orbit around the loaded pallets in a horizontal position.

Further, preferably, after finishing the vertical bundling of one of the two or more pail packs, the pallet is returned to the outside of the vertical bundling device, and the pallet is rotated by a predetermined angle by the rotary positioning means. Next, the position of the pallet to be vertically bound on the pallet is changed, and the pallet is transferred to the vertical binding device again to vertically bind the pail pack.

Further, the above-mentioned object is an automatic binding machine for continuously and automatically binding a pallet loaded with two or more pail packs together with the pail packs by a vertical binding device and a horizontal binding device. To a vertical binding position, and a horizontal transfer path that is installed in the vertical binding part, crosses the horizontal transfer path at a right angle, and circulates in an inclined surface having a desired inclination angle with respect to the vertical plane. And a vertical binding device having a binding band guide means.

Preferably, the vertical binding portion of the vertical binding device is provided with positioning means for positioning the pail pack and the pallet at the vertical binding position, and the vertical binding device hangs down on the pail pack. It has a handle raising means for rotating the handle attached in this state to the raised state. Further, a part of the binding band guide means is configured to be capable of advancing and retracting in the band circling direction, and a part of the binding band guide means capable of advancing and retracting advances and retracts the insertion position of the handle in the upright state. Further, in the middle of the horizontal transfer path, a rotary table for positioning the pail packs for positioning the pail packs to be bound at a predetermined transfer position is arranged.

According to a specific bundling mode of vertical bundling, a pallet loaded with two or more pail packs transferred from the supply conveyor is centered together with the pail packs on the way. Each time the pallet is placed on the supply conveyor, a pail pack type setting signal is input, and the operating positions and centering positions of various detectors are automatically set.

When the type setting signal is input, the rotation erection means of the handle moves and waits at the passage position of the handle of the pail pack. When the pail pack is introduced into the vertical binding unit together with the pallet, the handle in the hanging state is guided by the rotation erection means to be rotatably erected until it takes a substantially vertical posture. Next, the band guide means installed in the upper part inside the vertical binding unit descends and stops at a predetermined position. At this time, at the same time, the handle standing posture holding means presses the surface portion of the pail pack which is out of the passing position of the vertical binding bands of the left and right handles, and secures the standing posture. When held by the handle standing posture holding means, the rotation raising means moves backward and stands by at the original position.

Thereafter, the movable guide member of the band guide means arranged around the periphery of the pallet on which the pail pack is loaded is moved from the vertical binding band delivery / welding portion, and the band is inserted at the center of the bottom of the pallet. It is inserted into the space and the right and left handles of the pail pack in the upright state. When the band passage that is inclined around the pallet loaded with the pail pack at a predetermined angle with respect to the vertical plane is completed, the vertical binding band is fed out at a high speed from the vertical binding band sending / welding section and is guided along the band guide. When it circulates and its tip reaches the vertical binding band delivery / welding portion, the band feeding is stopped and the tip is automatically gripped. When the end of the band is gripped, the vertical binding band is sent out and welded to rewind the vertical binding band slightly,
By this unwinding force, the vertical binding band remaining inside is automatically released to the inner peripheral surface side of each guide member. Here, the band guide means returns to the original position. At the same time, the entire upper guide means is pulled up to the upper standby position. When the band guide means is moved to the standby position, the vertical binding band is completely removed from each guide member.

Next, after correcting the twist of the vertical binding band, the handle in the standing state is rotated downward in two steps until it is rotated obliquely downward to about 45 °. Subsequently,
After the vertical binding band is sent out and welded, the vertical binding band is finally tightened, and then the vertical binding band is sent out and welded toward the vertical binding unit and stopped, where the end of the vertical binding band is stopped. Weld and cut. By this final tightening, the handle of the pail pack is in a posture of hanging downward with the vertical binding band inserted. Finally, the vertical binding band sending out / welding portion returns to the original position,
Each operating member also moves to the original position to complete the vertical binding.

When the vertical bundling of one pail pack is completed, the pallet is returned to the rotary table on the upstream side of the supply conveyor, and the rotary table rotates 180 ° in the horizontal plane.
After being inverted, the above operation is repeated again to change the position of the second pail pack and to perform centering, and then the vertical bundling operation is performed to obliquely bunch the pail pack. When two or more pail packs have completed their vertical bundling, the pallets bound together with the pail packs are discharged from the vertical bundling device, transferred to a supply conveyor and transferred to a horizontal bundling device 15, where two or more pail packs are placed. The bale packs of (1) are collectively bundled horizontally by a horizontal binding band, and discharged to the outside of the machine by discharging means.

That is, the two pail packs 2 loaded on the pallet 4 have the loading position and orientation set in advance, and the pallet 4 transferred on the first feeding conveyor 11 is fed by the second feeding. It is transferred to the conveyor 12 and stopped at a predetermined position on the rotary table 13 installed in the middle of the conveyor 12. Here, the pail pack 2 is centered so that the pail pack 2 located on the front side in the transfer direction is the center of the conveyor. In order to perform vertical bundling accurately, it is necessary to introduce the pail pack 2 into the center of the vertical bundling device 20. However, since there is some variation in the size of the pallet 4 and the loading position of the pail pack 2 loaded on the pallet 4, it is necessary to correct this.
As described above, the rotary table 13 is provided on the second supply conveyor 12.
The tip of the pail pack 2 on the pallet 4 transferred to
For example, when detected by a photoelectric detector (not shown), the second
The driving of the supply conveyor 12 is stopped and the front and rear positions of the pail pack 2 are determined. Next, the cylinder 17a is operated in the extension direction to move the pallet centering arm 17
Is pushed forward and pushed out until the center position of the pallet 4 located on the front side is displaced by about 30 mm toward the pallet moving arm 18.

Here, the pallet centering arm 17
Moves to the standby position, and the cylinder 19a instead operates in the extension direction to cause the pail pack centering arm 19 to abut against the side surface of the front pail pack 2. When the pail pack centering arm 19 collides with the side surface of the front pail pack 2, the pallet moving arm 18 also moves forward in the center direction at the same time, and the pail pack centering arm 19 includes a pail pack (not shown). The operation is continued until the position confirmation sensor operates, and when the pail pack position confirmation sensor operates, both the pallet moving arm 18 and the pail pack centering arm 19 start retreating and the centering ends.

In these operations, when the vertical bundling of the front pail pack 2 is completed, the pallet storage section 12a and the pallet introducing conveyor 12b installed at the downstream end of the second supply conveyor 12 are reversed, Vertical binding unit 2
Return the pallet 4 from 1 to the rotary table 12,
After rotating the rotary table 13 by 180 ° in the horizontal plane, the same operation is repeated again and the pail pack 2 on the rear side is rotated.
Is moved to the front side and centering is performed at the same position. In addition, in this embodiment, when the pallet 4 is placed on the first supply conveyor 11, the pail pack type setting signal is input to the central control panel (not shown) each time, and the operation position of the photoelectric detector, The forward distance of the pallet centering arm 17 and the operating position of the pail pack position confirming sensor provided on the pail pack centering arm 19 are automatically set.

When the type setting signal is input, the handle 3
The rotating upright member 35d advances and descends, stops at the position where the handle 3 of the pail pack 2 passes, and stands by. When the pail pack 2 is introduced into the vertical binding unit 21 together with the pallet, the handle 3 in the hanging state is rotated by the rotation raising member 35.
It is guided by d and is rotated upright until it takes a substantially vertical posture as described above. Next, when the upper guide arch 27 installed inside the vertical binding unit 21 descends and the guide stopper 36 comes into contact with the upper surface of the pail pack 2 to be bound, the lowering of the upper guide arch 27 stops. At this time, at the same time, the plate piece 37b of the handle standing posture holding means 37 causes the vertical binding band 1 of the left and right handles 3 of the pail pack 2 to be connected.
The surface position deviated from the passing position of is held down to prevent downward rotation and maintain the standing posture. When the handle is held by the handle standing posture holding means 37, the rotation raising member 35d.
Retreats and waits.

Thereafter, the first lower fixed guide member 26a and the second lower fixed guide member 26b are unwound from the vertical binding band feeding / welding portion 23, and the upper and lower deck boards 4a, 4b of the pallet 4 and the central portion thereof. Is inserted into the band insertion space IS formed between the left and right spacers 4c. At the same time, at the same time, the first to sixth upper movable guide members 25a, 25c, 25d, 25f, 25 of the upper guide portion 25 are formed.
g and 25i move in the circumferential direction of the vertical binding band 1 and are connected to the upper and lower fixed guide members. The upper movable guide members 25a, 25c, 25d, 25f, 25g,
When 25i is moved, the second upper movable guide member 25c and the fifth upper movable guide member 25g are inserted into the left and right handles 3 of the pail pack 2 in the upright state.

When the band passage is completed, the vertical binding band 1 is fed out at a high speed from the vertical binding band delivering / welding portion 23 and circulates along the band guide, and the tip thereof is fed to the vertical binding band feeding / welding portion 23. When reaching, the band feeding is stopped and the tip is gripped by a known gripping mechanism (not shown). When the end of the band is gripped, the band winding mechanism (not shown) of the vertical binding band feeding / welding portion 23 is actuated to slightly rewind the vertical binding band 1 and leave it inside by the unwinding force. The vertical tying band 1 has the guide members 25a to 25i and 26 having the above-described mechanism.
It will come off from a and 26b. Subsequently, the movable guide members of the upper guide portion 25 and the lower guide portion 26 return to their original positions, and at the same time, the entire upper guide portion 25 is pulled up to the upper standby position. These guide parts 25, 2
When the 6 is moved to the standby position, the vertical bundling band 1 includes the guide members 25a to 25i and 26a, 26.
Completely removed from b.

Next, the pallet 4 is slightly retracted to correct the twist of the vertical binding band 1, and then the fluid pressure cylinder 43 supporting the center of the rectangular frame 42 operates in the extending direction to form a disc shape. The stopper 44 comes into contact with the upper surface of the pail pack 2 and stops, but by this, the handle 3 in the upright state is rotated downward in two steps to the first hanging-off means 38 and the first handle removing means 38. (2) At the same time when the handle removing means 39 is lowered, the band holding fluid cylinder 40c
Is operated to prevent the movement of the pail pack 2 during bundling and the movement of the vertical bundling band 1,
With 0, the binding band 1 is pressed together with the pail pack 2 from above. Subsequently, the first handle removing means 38 is rotated to press the upper end portion of the handle 2a in the upright state to incline up to about 45 ° obliquely upward, and then the second handle removing means 39 is lowered. Then, the handle 3 in the above-described posture is pushed down from above and rotated diagonally downward until it reaches approximately 45 °.

Subsequently, after the vertical binding band 1 is fully tightened by the vertical binding band sending / welding portion 23, the vertical binding band sending / welding portion 23 leans toward the vertical binding unit 21 and stops. Then, the ends of the vertical binding band 1 are welded and cut here. By this full fastening, the handle 3 of the pail pack 2 is in a posture of hanging downward with the vertical binding band 1 inserted. Finally, the vertical binding band delivery / welding portion 23 returns to its original position, the fluid pressure cylinder 43 is actuated in the contraction direction, and the first handle removing means 38, the second handle removing means 39, and the band retainer. Raise 40 to complete vertical bundling.

When the two pail packs 2 have completed their vertical binding, the pallets bound together with the pail packs 2 are discharged from the vertical binding device 20, and the third feeding conveyor 14
Horizontal bundling device 1 that is transferred to a transfer path and installed in the transfer path
5, the two pail packs 2 are collectively bundled horizontally by the horizontal binding band 5 and discharged from the discharge conveyor 16 to the outside of the machine.

In addition, the automatic binding machine according to the present embodiment can be switched to a completely manual mode in addition to the above-described series of automatic operation modes, so that, for example, an operator makes individual operations in the manual mode at his own discretion. It can also be done arbitrarily.

As is clear from the above description,
According to the automatic bale pack bundling method and the automatic bundling machine according to the present invention, the lower part of the pallet is simultaneously inserted into each of the two or more pail packs loaded on the pallet while the vertical binding band is inserted through the handle. Since it is possible to bind diagonally with the center part, the fork of the forklift does not hit the vertical binding band and it is possible to prevent damage, and the vertical binding band is inserted into the handle of the pail pack even after binding. It is extremely unlikely to slip because it is hooked on the crosspiece at the bottom of the pallet. Further, since a series of these binding operations can be automated, great labor saving can be achieved.
