Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a band feeding device that automatically feeds and rewinds a binding band in a binding machine that binds packages with a binding band, that is, a binding band dispenser. More specifically, a pulley-type looper is disposed on the exit side of the binding band dispenser, and when the band is hung around the package at the beginning of binding, the band stored in the looper is fed and tightened. The surplus band relates to a tie band dispenser that automatically pulls back into the looper for storage.
[0002]
[Prior art]
A band dispenser (hereinafter referred to as a dispenser) used in a binding machine for binding a package with a binding band (hereinafter referred to as a band) repeats the supply and withdrawal of the band every time the package is bound. Therefore, the belt wound in a coil shape repeats normal rotation and reverse rotation by the driving device for each binding. When the material of the belt is synthetic resin and the weight is light, the rotational load applied to the driving device is small, but when the material of the belt is iron or copper, the weight of the coil of the belt is 250 to 500 kg, and the rotational load of the driving device is As the size of the motor becomes larger and the motor used becomes larger, the outer shape of the apparatus becomes larger and the manufacturing cost becomes higher. In addition, if the coiled belt is rotated forward and backward, it will cause urumi and misalignment, and if this is repeated, it will not be possible to feed out, so there is a strong need for improvement.
[0003]
[Problems to be solved by the invention]
In view of such circumstances, the present invention aims to reduce the size of the driving device, simplify the control, and reduce the cost by rotating the coiled strip on the dispenser forward and backward as usual, i.e., only sending out, It is another object of the present invention to provide a binding band dispenser excellent in workability for preventing work stoppage due to band slurries and displacement.

DETAILED DESCRIPTION OF THE INVENTION
In the present invention, by arranging a pulley-type looper on the outlet side of the dispenser, the coiled belt is rotated in the forward direction, that is, only on the delivery side. As a result, the load on the driving device is reduced, so that the driving device is downsized, the control is simplified, and the manufacturing cost is reduced. In addition, there was no coiling belt slack and misalignment due to forward and reverse rotation as in the past, and work interruption troubles could be solved.
Hereinafter, the present invention will be described in detail with reference to an example.
[0006]
【Example】
1 is a front view of the present invention, FIG. 2 is a side view of FIG. 1, FIG. 3 is a plan view of FIG. 1, and an inner cylinder portion of a band 4A wound in a coil shape in FIG. Then, the expansion / contraction cylinder 8 is expanded and contracted, and the expansion / contraction cylinder 8 is expanded to fix the coiled band 4A. The expansion / contraction cylinder 8 is rotated by the driving device 7 and the binding band 4 is sent out. The driving device 7 includes an electric motor 9 with a brake, a bevel gear reduction mechanism 10 and the like. Since the link mechanism is a general-purpose technology, the description thereof is omitted. A main shaft 11 that rotates while supporting the expansion / contraction cylinder 8 is supported by a bearing 12. The bearing 12 is attached to a frame 13 disposed on the bed 6.
[0007]
The belt 4 delivered from the dispenser 2 enters the next pulley-type looper 3 and then enters the binding machine 5. FIG. 4 shows the relationship among the package 38, the binding band 4, and the binding machine 5. The binding band 4 exiting the looper 3 passes between the feed wheel 40 and the backup roll 41 of the binding head 39. Here, the bundling band 4 is given a feeding force, goes around the band guide ring 34 disposed around the package 38, goes around once again, returns to the bundling head 39, and the band tip 4B is clamped to the clamping device 33. Held in. Next, after the feed wheel 40 is reversed and the binding band 4 is wound and shrunk to tighten the package 38, the upper and lower binding bands are joined by the sealing device 42, and the surplus band is cut by a cutting blade (not shown). Finish the bundling work. When the feed wheel 40 is reversed and the binding band 4 is wound and contracted, if the returned binding band 4 is left as it is, it becomes tangled or twisted and the next binding work cannot be performed. The looper 3 has a function of winding the returned binding band 4 so that the next binding operation can be performed smoothly.
[0008]
Another function of the looper 3 is that when the binding head 39 hangs the binding band 4 around the package 38, the binding band 4 stored in the looper 3 is automatically stored. Is to supply. As a result, the dispenser 2 does not operate every time it is bundled, and the dispenser 2 may be sent out when the bundling band 4 stored in the looper 3 runs out. Next, the looper 3 will be described.
[0009]
As shown in FIGS. 1, 2, and 3, the belt 4 that has been turned 180 degrees by the deflector roll 14 is next to a plurality of hooked pulleys that are rotatably attached to the same shaft 31 that is disposed on the lower side. After entering the front pulley 15 and changing the direction by 180 degrees, the front side of the plurality of fixed vehicles with hooks that are installed on the upper side and are rotatably attached to the same shaft 32 engaged therewith Enter fixed car 20 and turn 180 degrees to enter lower pulley 16. In the following, the belt 4 repeats in the same manner as described above, and passes through the deflector roll 24 disposed on the upper side through the fixed pulley 21, the moving pulley 17, the fixed pulley 22, the moving pulley 18, the fixed pulley 23, and the moving pulley 19. The deflector roll 25 turns 90 degrees and enters the binding machine 5. The deflector rolls 14 and 24 are rotatably attached to shafts 28 and 29 attached to the arms 26A and 27A of the pillars 26 and 27 attached to the bed 6. The deflector roll 25 is also rotatably attached to a shaft 30 attached to the arm 27B of the column 27. In addition, the same shaft 31 to which each of the above-described moving pulleys is attached slides up and down along guides (not shown) provided on the columns 26 and 27.
[0010]
In the present invention, in order to store a large amount of belt 4 in the pulley-type looper 3, a multi-stage system is adopted in which a plurality of moving pulleys and a plurality of fixed vehicles engaged with the pulleys are arranged. When entering the next fixed vehicle, if the two axles are parallel, the belt 4 may come off or bend and become inoperable. For this reason, as a result of intensive studies, the inventor has found that the above-mentioned trouble can be solved by setting the same axis for the fixed vehicle to a horizontal plane with respect to the same axis for the moving pulley and a tilt angle K in the clockwise direction as shown in FIG. Invented and tested, it was confirmed that the steel strip had a width of 32 mm, a thickness of 0.9 mm, and the tilt angle was 18 degrees. In the present invention, the mounting holes 46 and 47 of the beam 43 for attaching the fixed vehicle support bracket 35 are long holes so that the inclination angle can be easily adjusted with the bolts 44 and 45 in the field.
[0011]
Since the looper 3 is a multi-stage type, a considerable amount of the belt 4 can be stored. However, when the binding is repeated, the belt is consumed, and the position of the moving pulley is gradually raised, and the storage of the belt becomes zero. In the present invention, the position of the moving pulley in front of which the storage amount of the belt becomes zero is detected by the photoelectric tube position detectors 36 and 37 installed in the columns 26 and 27, and this signal is fed back to a control device (not shown) to supply the dispenser 2 Is operated to feed the binding band 4 into the looper 3 so that continuous work can be performed.
[0012]
【The invention's effect】
In the present invention, a pulley-type looper is arranged on the outlet side of the dispenser, so that the conventional dispenser rotates forward and backward, and the belt is fed back. However, the dispenser of the present invention has a pulley-type looper on the outlet side. By installing the dispenser, the dispenser only has a function of rotating forward, that is, feeding out the belt. This reduced the size of the dispenser drive, simplified control, reduced costs and reduced failure. In addition, when the dispenser is rotated in the forward and reverse directions, there are many troubles that the coiled belt is loosened or tangled and the operation becomes impossible. It is also an excellent breakthrough dispenser.
