Description

[Detailed description of the invention]

The present invention relates to an automatic tying device that completes the operation of wrapping a bundled object with a thread or string, tying the end of the string, and tying it with a single touch. This is a vertical automatic tying device that has never been seen before, and tying can be completed with the simple action of placing the cord on the handle and pushing the handle downward with one hand. To explain the outline of the device of the present invention, as shown in FIG. While pushing the string stretched over the female type A' of the string guiding mechanism provided in front, place it on the workbench while pushing it with a binding object. Next, hold the handle 5 and push down the string passing tube to tighten the string. The guiding mechanism engages, the tying lever mechanism operates, and the fine twilling is completed as shown in FIG. 16. In this way, the structure is such that the binding can be completed with the easy action of pushing the handle downward. This is an extremely convenient device that allows you to hold a load of agricultural products, seedlings, etc. with one hand, place it on the workbench while pressing it against the string, and then press down on the handle to bind these items with the string.
When the tied object is in an upright orientation, it is easier to tie the string with the tied object B lying on its side than with a device that turns the string horizontally and ties the end of the string into a bow knot (or a single bow knot). It is much more difficult to run the string in the vertical direction and tie a bow (or single bow) at the end of the string, and the mechanism of the device becomes complicated. The present invention strives to make the mechanism as simple as possible, and adopts a method in which the string is stretched in the vertical direction in advance. There have been few examples of this ultra-thin tying device in the past, and the one provided here is completely unique in this respect. The basic concept of the bundling device of the present invention is as described above, but to explain it in more detail, a thin K is stretched from top to bottom at the center of the front of the device, and the bundled object B is tied as shown in Fig. 7. Place this on the workbench C while pressing the string K. At this time, the lower part of the string K passes from below the bundle B, over the female mold A' of the string guiding mechanism, through the string holding rod 46', and continues to the string end tail K'. In this state, the handle 5 is pushed down to engage the fine guide mechanism A with A', and then the handle is released and the string tying is completed while the string threading tube is raised to its original position by the force of the spring 33. . For details, see Rack 2.
9 and various movements by the gear mechanism linked to this,
By the action of iron-inserting the fine guidance mechanism A into the same A', and by releasing the force that pushes down the handle 5, and by the actions performed when the handle returns to its old position, each mechanism also returns to its old position. The completed work is summarized as follows.

...Due to the retreat of the hook 45' of the string catcher 45. [W] Cutting the end of the string...The lever 56 provided at the end of the rack operates on the bending lever 53, pulls down the wire 60 and the cutter stand 50, and raises the cutter 50' to cut it into pieces. To explain the above actions in order, three actions are performed as the rack 29 is carried by lowering the handle. First, the cam 34 moves the shaft 27' of the pinioso
As the pinion rotates, the roll 20 of the string receiving tube 19 that engages with the cam rises, and the string receiving punch rises. The upper part of the string receiving tube has a shape in which half of the cylinder is cut obliquely in the vertical direction (Fig. 6), so the thin part that was previously passed onto the tube as it rises is To the right side of the tube (
(front view) It will slide down, resulting in the situation shown in Figure 8. (Note that when the string receiving tube 19 rises, the string push-up tube 18 is pulled up by the pin 21 (FIG. 4) provided on its chest.) Next, by the rotation of the thin winding tube 17, the projecting plate 17
The string K is wrapped around the outer periphery of the elevated string receiving tube 19 through the notch A (FIGS. 11 and 12). In other words, a horizontal string theory is formed. Furthermore, the lever cam 47 on the shaft 37 rotates due to the rotation of the gear 38 (due to the engagement of the long pin 43 implanted in the cam 34 and the bar cam 42), and this lever cam is activated by the narrow presser punch 46 and the string catcher punch. 4
5 and rotate them counterclockwise, the former string presser releases the string that was being held down, and the latter string gripper,
The hook 45' at the tip thereof is driven to enter into a notch suitable for the string receiving tube string push-up tube 18. At the final stage of lowering the handle 5, the male type A of the fine guide mechanism is inserted into the female type A', and in this state, the string reaching the upper part of the bundle B from the fine nozzle 13 is shown in FIG. As shown in Figure 14, it will be pushed into the inside of the string receiving tube 19 in a U-shape (vertical section formation). As a result of the above action, a vertical U-shaped section R is formed within the horizontally formed section, as shown in Figure 14.
As shown in the figure, the hook 45' enters into the string R, and engages with the inside part of the end of the string K'. Next, the force that lowered the handle 5 is released. That is, as a result, the thin tube 4 starts to move back to its original position by the force of the spring 33, and each mechanism also takes a movement opposite to that described above in order to return to its original position. First, the hook 45' pulls out the gripped end of the string through the inside of the string R through its notch 2, and at the same time pulls out the end rod 46 of the string presser 46.
' again enters the cavity 12 of the male part A of the fine guide mechanism and presses the string, and the fine nozzle 13 rises to apply tension to the string leading to the fine guide R, while the string receiving tube 19 holds the string. It descends with the push-up tube 18 and wraps around itself,
By releasing the horizontal string loop, a knot will naturally form (Figure 15). Finally, we installed the -ru 5 at the end of the rack.
6 actuates the bending lever 53, lowers the cutter stand 50' through the wire 60, and cuts the cutter 5's strand. An example of implementing the present invention will be described with reference to the drawings. In Figures 1 to 4, 1 is the machine base, 2 is a support provided at the rear of the machine base, and the lower end of a stringing tube 4 is attached to the upper end of this support by a pivot 3, and 4' is a support provided at the rear of the machine base. This is the leg of the string tube. As shown in FIG. 1, the string passing tube is bent in an arc shape, and a handle 5 is protruded from the tip thereof, and guide rolls 65, 65 for the string to be let out from the winding K are provided inside the tube. ' is installed. 6 is a male type of the string guiding mechanism provided at the tip of the string passing tube 4, as shown in the figure, at the tip of the string passing tube,
From this, three protrusions 7, 9, 11 are protruded in a comb-like shape,
A U-shaped gap 8, 10, 12 is formed between each protrusion, and a guide 7', 9', 11' is provided at the tip of each protrusion, forming a male type A of the guide mechanism. 13 is a narrow nozzle, and 13' is a string groove provided at the lower end of the narrow nozzle. 14' is an upright machine frame installed in the middle of the machine base, 15 is a horizontal machine frame that continues above the machine frame 14, and a metal 16 is provided at the front position of the machine frame 15, and a string is attached to this metal. Induced female type A
A narrow ported pipe 17 forming the outer side of ' is iron-bonded. 17' is a semicircular projecting plate formed on the upper part of the thinly wound tube;
A notch is provided on its side edge, and a gap is provided between it and the main body. Now, to explain the female type of the string yielding mechanism, Figure 3~
As shown in FIG. 6, a string push-up tube 18 is installed inside the narrow-wound tube 17, and a string receiving tube 19 is installed inside the narrow push-up tube. teeth,
A roll 20 is pivotally supported 20' at its lower end, and a pin 21 is provided at its upper back. Further, the string push-up tube 18 and the string receiving tube 19 are interlocked with each other because the pin 21 of the latter 19 engages in a vertical groove 22 provided on the back of the former. As can be seen in FIG. 6 when both are seen from the front, the upper right side of the tubular body is cut off to form sloped portions S and S'. 23 is a pin provided on the string receiving tube 19, 24 is a pin provided on the coupling 1, and a spring 25 is stretched between both pins to pull the string receiving tube 19 downward. Further, as shown in FIG. 5, long notches C and C are provided passing through the string receiving tube 19 and the thin push-up tube 18 from side to side.
Reference numeral 26 denotes a gear fixed to the lower part of the narrow winding tube 17, which meshes with a gear 40 in a series of gear mechanisms to cause the narrow winding tube to rotate, and the string receiving tube and narrow push-up tube to move up and down. . Next, the cam machine will be explained. Reference numeral 27 is a shaft installed in the machine base 1, 28 is a pinion provided on the shaft and meshes with the rack 29, and 30 is a guide for the rack. The end of the leg 4' of the string passing tube 4 is attached to the support 29' provided at the rear end of the rack by a pivot 31', and is stretched between the pivot and the pin 32 on the machine frame 14. It is pulled to the right by the spring 33. For this reason, the stringing tube and the rack take the position shown in FIG. A cylindrical cam 34 is fixed on the shaft 27' above the pinion 28, 35 indicating the lower position of the cylindrical cam and 36 indicating the top of the cam. Therefore, when the handle 5 is pushed down, the leg 4' of the stringing tube and the rack 29 move to the left against the spring 33 (Fig. 1), and the pinion 28 that engages with the rack rotates, causing the cylindrical cam 34 to move to the left. rotates. To explain the gear mechanism driven by the rotation of the cam 34, a series of gear mechanisms mounted on the lower surface of the horizontal machine frame 15 are suspended from the horizontal machine frame 15 as shown in FIG. A gear 38 is attached to the attached shaft 37, 39 is a gear that meshes with the gear 38, and 40 is a gear fixed to the same shaft 41 as the gear 39, which is attached to the thinly wound tube 17. gear 26
meshes with Further, a lever cam 42 extending outward from the boss portion of the gear is fixed to the lower surface of the gear 38, and a long pin 43 embedded in the inner bottom surface of the cylindrical cam is engaged with the lever cam. Note that 47 is a small lever cam fixed to the 37 shaft, and is provided on the upper surface of the horizontal machine frame 15.
Next, the string tying lever mechanism will be explained. This mechanism consists of two levers whose bases are pivotally attached to a support shaft 44 provided on the upper surface of the rear part of the horizontal machine frame 15. A rising leg 45a is provided at the tip of the horizontal arm, and a horizontal hook 45' is provided at the upper end of the leg, while a string holder 46 is provided at the tip of the horizontal arm.
A and a horizontal rod 46' at the upper end of the chest. The hook 45' of the former string gripper is connected to the string receiving pipe 19.
The rod 46' of the string presser is positioned immediately in front of the fine winding punch 17 and presses the end of the string or presses the narrow part. To hold down
Rotation movement is performed around the support shaft 44. This spreading movement is due to the movement of the cam 34. Reference numeral 44' denotes a spring attached to the support shaft 44, which acts to maintain the two shafts 45, 46 at a predetermined angle as shown in FIG. 45b is a protruding rod provided at the base of the village 45, which engages with a lever cam 47 fixed to a portion where the shaft 37 protrudes from the upper surface of the horizontal machine frame 15. The lever cam 47 is retractably mounted on the base 47',
When rotating to the left, the portion 47 is configured to bend relative to the portion 47'. Next, regarding the cutter mechanism, reference numeral 48 is an L-shaped punch attached to the upper end of a column 51 fixed on the machine base 1 at the front position of the machine, and a force cutter mount 50 is attached to the vertical part 48' of the punch. A cutter 50' is attached to the cutter stand. The upper end of the vertical part 48' of the core L-shaped punch is located at the lower end of the notch A of the projecting plate 17' provided at the upper part of the thin winding village 17.
The cutter 50' is located below. Also,
A pin 52 is provided below the support column 51, a bent short lever 53 is pivotally attached to the pin, a pin 54 is provided at the center of the lower piece 55, and the lower piece 55 can only be moved in one direction. The roll 56 is provided on the rack guide 30 and is brought into contact with the roll 56 provided on the rack guide 30. The upper end 59 of the lever 53 and the lower end 58 of the power lever mount 50 are connected to a wire 60.
57 is a wire guide roll. 61 is a cover on the front side of the device, 62 is a bundle receiving guide plate, 63 is a winding string holder, 63' is a shaft thereof, and 64 is a thin guide hole provided at the upper end of the shaft. The device of the present invention has the above-mentioned configuration, and its operation will be explained below. The thin K passes through the string passing tube 4 and is guided downward from the string nozzle 13, and is held between the rod 46' of the string holding village 46 and the cover 61, with the string end being K'. Now, to tie the bundle B with a string, press the string with the bundle B and place it on the binding table C as shown in Fig. 7. At this time, the string K is easily unwound from the bobbin and is given an appropriate tension. At this time, the lower part of the thin K passes through the upper surface of the female mold A' of the string transfer mechanism and extends rearward. In this state, push down the handle 5 by hand. As a result, the string passing tube 4 first rotates downward and the rack 29 is moved backward by its legs 4', so that when it engages with the rack, the pinion 28 rotates, and the cam 34 fixed to its shaft 27' is rotated in the direction indicated by the arrow. Rotate in the direction. (Fig. 3) That is, before the male part A of the string induction machine engages with the female part A',
The roll 20 engaged on the cylindrical cam 34 rises, and the string receiving tube 19 begins to rise. Since the right half of the tube is configured with a neck slope S when viewed from the front, the thin K on the top surface of the tube slides on the forehead slope and is pushed to the right, and the string receiving tube 18 is pushed along the side surface of the tube. Attach the top (Fig. 8) and cylindrical cam 3.
As the rotation of cam 4 progresses, the long pin 4 provided as a shield on the inner bottom surface of the cam
3 pushes the lever cam 42 fixed to the back of the gear 38,
Since the gear 38 is rotated, the rotation is transmitted to the gear 26 through a series of gears 39 and 40, and the narrowly wound tube 17 integrally connected to the gear 26 rotates. In this way, as shown in FIG. 10, the string K rotates while holding the string through the string gripping notch A provided in the green side of the projecting plate 17' above the tube, so that the string K is connected to the string wrapping tube 17 and the projecting plate 17'. The string is passed through the gap provided between the strings and wrapped around the tube body of the string receiving tube 19. At this time, since the string receiving tube is raised, the string rests on the upper twill portion of the narrow push-up tube 18. Furthermore, since the small lever 47 attached to the shaft 37 of the gear 38 is also rotating at the same time as the lever cam 42, the lever cam is attached to the string presser mallet 46.
Press and rotate it counterclockwise around the 44th axis,
The rod 46' at the tip also moves outward accordingly,
Release the end of the string K' that you were holding down. On the other hand, the cylindrical cam 3 mentioned above
When the cylindrical cam rotates to a certain extent, the contact engagement between the long pin 43 provided as a shield on the inner bottom surface of the gear 38 and the lever cam 42 on the back surface of the gear 38 is disengaged, and the rotation of the gear 38 is stopped. Therefore, the rotation of the wrap-around tube 17 also stops, but during this time the string forms a complete line (FIG. 12). Next, the operation of the fine guidance mechanism will be explained. When the handle 5 is further lowered, the cylindrical cam rotates further, and the roll 20 that engages with the cam is pushed up to the highest position.Therefore, the string receiving tube 19 also rises to the highest position, but at this time, the rear wall of the tube The pin 21 attached to
Since it reaches the upper end of the vertical groove 22 on the wall of the thin push-up tube 18 and pushes the narrow push-up tube upward, both the string receiving tube 19 and the narrow push-up tube 18 rise as shown in FIG. , the details wrapped around the string receiving tube 19 also rise. In this state, the male mold A of the fine guide mechanism enters into the female mold A'. The thin K guided to the male mold A is combed into the string grooves 7', 9', and 11' provided at the tips of the comb-teeth-like projections 7, 9, and 11, and then inserted into the female mold A'. To explain in detail, the protruding pieces 7 and 9 are introduced into the inside of the string receiving tube 19, and the protruding pieces 11 and the string nozzle 13 are on the outside of the tube 19, so that the string is inserted as shown in FIG. Then, from the thin/zuru 13 to the string groove of the protruding piece 11, it ascends from this point, crosses the hem of the string receiving tube 19, reverses down and enters the string groove of the protruding piece 9, and then horizontally moves the protruding piece 9 It is formed in a bent state in which it crosses over to the string groove, rises, crosses the rear wall of the string receiving tube 19, and reaches the bundle B. At this time, part of the string can be seen through the elongated hole. The overall shape of the thin body described above is the first
It is shown in Figure 4. Next, regarding the string tying movement, the small lever cam 47 attached to the shaft 37 presses the protruding rod 45b of the string grip village 45 and rotates the string grip village counterclockwise. The provided hook 45' enters into the elongated through hole of the string receiving pestle 19 and the thin push-up village 18, and the end K' portion of the string is hung on the hook. Further, the lever cam 47 is rotated and disengaged from the protruding rod 45b, so the string catcher 45 returns to its old position by the action of the linear spring 44', and the end of the string hooked on the hook is pulled into the string position. At the same time as the cord presser rod 46 returns to its old position, the cord presser rod 46' enters the gap 12 between the protruding piece 11 and the narrow nozzle 13, and presses the lower end of the protruding piece 11 and the string nozzle 13. It advances above the local part D (Fig. 14) of the stretched string. This is the lowest state in which the handle 5 is pressed down. Next, when the pressure on the handle is released, each mechanism attempts to return to its old position in the reverse order described above by the force of the spring 33.
First, the male die A rises, and the string receiving punch 19 starts to descend, releasing the string wound around the tube body and making it free, but the rod 46' presses down the small part D. At the same time, the string nozzle 6 rises and pulls the string, so that the string forms a knot and binds the object B. Handle 5 and string/zuru 13
Just before it completes its ascent, the roll 56 provided at the front end of the rack 29 presses the lower part of the bending lever 53 and rotates the lever, which pulls the wire 60 and connects it to its upper end. The cutter stand 50 is lowered and the cutter 50' is raised to cut the thin K. Thus, the bundle B is released. On the other hand, the other end of the cut string is pressed by the rod 46' of the string presser 46 (FIG. 16) and then returns to its original state, completing the entire operation of the device. At the final stage of operation, the string is stretched between the thin nozzle 13 and the string holding rod 46', so that the next tying operation can be carried out immediately. The tying device of the present invention is characterized in that by pressing the handle downwards, the string can be hung on the bundled object and the ends of the string can be tied. It is convenient and can be applied to any product, large or small, and can easily be fully automated using power.
