[Problem that the idea aims to solve]

Use the above conventional structure to bind cut flowers, green onions, asparagus, and other soft and long vegetables. If you try to do this, the objects to be bound will be damaged by the plowing pressure from the packer. This has the disadvantage of causing a decline in quality, and if the binding tension of the items to be bound is too strong, the binding may deteriorate. If the item is damaged and weakened, the binding will not be sufficient and will become loose, so this binding It was difficult to finely adjust the tension, making it impractical for practical use. Therefore, when bundling objects as described above, it is necessary to manually supply the objects. However, the present invention is suitable for manually binding objects as described above. We aim to provide a general-purpose binding machine that has a compact shape and can work safely. The purpose is

[Means to solve the problem]

The characteristic configuration of this invention is that a drive is placed below the workbench for placing and supplying objects to be bound. A constantly rotating body that receives power from a source and is externally attached to the rotating shaft via a one-turn clutch mechanism. and a needle that supplies a knotting mechanism and a binding rubber string from both ends of the rotating shaft. The connecting mechanism is arranged below the workbench. and the needle is arranged so as to protrude above the workbench, and the one-turn crank An operating tool is provided for activating the latch mechanism.

[0005]

[Effect]

Since soft objects are bound using rubber strings, the elasticity of the rubber strings itself is reduced. It can be used to bundle items with appropriate tension, and the items to be bundled can be bundled along the workbench. When placing and feeding the string manually, the needle that swings greatly to feed the string is It operates above the workbench, so the operator can visually monitor its movements while working. . In addition, the power for one rotation for binding operation is supplied by branching from both ends of one rotating shaft. At the same time, since this rotating shaft is also used as the supporting shaft of the rotating body, its function makes it possible to avoid bundling. One rotation power is supplied to the knotting mechanism and the needle, which are located at separate locations. The transmission system can be constructed with a simpler structure compared to the case where the transmission system is supplied with the power supply. Moreover, the one-turn clutch mechanism is configured to be activated by manual operation of the operating tool. You can set the number of items to be bundled to any desired number, and no pressing force is applied to the items themselves. Never.

[0006]

[Effect of the idea]

Therefore, cut flowers, green onions, soft long vegetables such as asparagus, and other soft knots can be used. It is possible to effectively automatically bind bundles with moderate tension without causing damage. In addition, by simplifying the transmission system, the entire device can be made smaller, and the bundling is highly versatile. We are now able to provide the machine.

0010 As shown in FIG. 11, the binding rubber string 4 is a string attached to the surface of a band-like rubber plate main body 4a. Forming streak-like unevenness 4b that extends in the longitudinal direction to improve longitudinal sliding. , is constructed so that an appropriate tension can be obtained when the objects to be bound a are bundled.

[0011] The knotting mechanism 3 is provided in a knotterbill type, and holds one end of the rubber string 4 by pinching it. At the same time, the new string part supplied by the needle 6 and the held string A string holder 42 that sets the parts in an overlapping state, and both overlapped strings as described above. A knot holder 42 is provided, and a knot holder 43 is provided to operate the knot by winding the part. and the node building 43 are arranged so that their rotational drive axes are parallel to each other, and the supporting brackets are A pair of timing gears 45 and 4 drive these gears. 6 is attached to the nodule drive shaft 21. And near the upper side of the nodal building 43 At the same time, when the knot bill 43 is in operation for winding the string, that is, it is held in place by the string holder 42. The rubber string portion 4c that has been wrapped around the object to be tied and the rubber string portion 4d that has been wrapped around the object are wound and tied. In order to lock and hold each of the string portions 4c and 4d at a predetermined position when forming the In addition to providing the string guide member 47, after the string winding operation by the knot building 43 is completed, The string guide member 47 is moved in a direction substantially perpendicular to the direction in which the needle 6 supplies the string. A means of transportation A is provided. To be more specific, as shown in FIGS. 2, 7, and 10, The string guide member 47 is provided in a plate shape to cover the upper part of the knot building 43, and is used to guide the movement of the tied object a. A locking recess 48 is formed along the movement direction into which both the string portions enter and engage, and the swing support is The holding arm 49 is capable of swinging freely around the axis along the axial direction of the knot drive shaft 21. It is pivotally supported on a support bracket 44. The swing support arm 49 is supported by a spring 50. A cam 51 provided on the tuberosity drive shaft 21 and oscillatingly biased toward the above-mentioned working position. The cam follower 52 abuts and engages with the cam follower 52 and retreats from the working position and the position above the knot building. The above-mentioned moving means A is constructed so as to be able to oscillate between the avoidance positions and the avoidance position. child In this manner, the string guide member 47 is in the retracted state while being wound around the knot building 43. By switching to the active position, the string comes off from the knot building 43 and the knot operation ends. It becomes. The rotation axis 29 of the needle 6 is aligned with the rotation axis of the knot building 43 and the string holder 42. The rubber cord 4 is located above the center of the rotation axis, and the rubber cord 4 is connected to the knot building. 43 and the string holder 42 at a substantially uniform level, and , the needle support case 28 is provided in an inclined position so as to provide a large nodule space. It is set as.

0012 A stopper is provided near the string guide member 47 to close the entrance of the locking recess 48. By providing a string gathering member 53 that can be freely switched between a closing position and a position opening the entrance part. In both cases, when the knot building 43 operates to wind the string, the string gathering member 53 is placed in a retaining position. A posture switching means B for switching is provided. In other words, as shown in Figures 7 and 8, , the string gathering member 53 is supported swingably around an axis X2 perpendicular to the axis of the knot drive shaft 21. It is pivotally supported on a holding bracket 44 and is biased to swing toward the open position by a spring 54. At the same time, the continuous cam follower 55 comes into contact with the cam 56 provided on the node drive shaft 21. It is configured to perform a switching oscillating motion.

[0013] Moreover, as shown in FIGS. 19 and 20, there is a gap between the knot building 43 and the string holder 42. , a rubber string 4 whose one end is held by a string holder 42 when the needle 6 is retracted. A cord guide plate 57 is provided for regulating the cord to a predetermined standby position, and this cord guide plate 57 is The thickness of the rubber string is determined by the rotation trajectory of the outer end of the string cutting cutter 58 provided in the string holder 42. They are placed close to each other with a very small distance between them.

[0014] Next, the binding operation procedure will be explained. The end of the rubber string 4 is held between the string holder 42 From the standby state where the needle 6 is held in the upper standby position, the object to be bound a is placed on the workbench. 7 and feed it along the lower side of the string until the object to be bound a reaches near the binding area. Then, the object to be bound a comes into contact with the actuating piece 27 of the hand switch SW2, and the one-turn clutch is activated. The mechanism 18 is activated and the driven shaft 16 is driven one revolution. Then, as shown in Figure 12, The needle 6 operates to feed the rubber string 4 toward the knotting mechanism 3. this At this time, the string wound around the string guide roller 40 is further wound as the needle 6 operates. The string is wound in the direction in which it is drawn, and the string is almost at a standstill. And then Before the handle 6 reaches the maximum plunge position, the string pulling member 53 first comes out of the open position. Switch to the stopped position. Immediately after that, the knot building 43 rotates and the string holder 42 and a string portion 4d supplied by the needle 6. They are wound together to begin the knotting operation (Fig. 13). In addition, at this time, the string guide member 47 It is set in the working position.

[0015] After that, when the needle 6 reaches the maximum plunge position, the string holder 42 is moved from that point on. Rotate to align both string portions 4c and 4d, and the string portions 4c and 4d are wound up by the knot building 43. (Fig. 14, Fig. 15). Then, when the winding operation of the knot building 43 is completed, , the string gathering member 53 is switched to the open position, and the string holder 42 is The cutting cutter 58 approaches the string guide plate 57 and cuts the string portion, and then the string guide plate 57 The member 47 swings laterally from the working position to remove the string wrapped around the knot building 43. Then, the knotting operation is completed (FIGS. 16 to 18). At this time, the winding work of Node Building 43 Near the end of the movement, the string holder 42 releases the held string portion 4c, In addition, the supply string portion 4d by the needle 6 is newly held and held, and then the cutting cap is The supply string portion 4d is cut by the cutter 58. As mentioned above, needle 6 Since the rubber string 4 is hardly let out from the side, the rubber string 4 is in a stretched state during the knotting operation. , and when the string was cut, it was first held by the string holder 42. The string portion 4c is in an extremely stretched state due to its winding action, so it does not appear to be in a pinched state. When the condition is released, it comes off the loop formed by the nodule building 43, The knot of the binding string becomes a so-called one-sided knot (see FIG. 21). As a result, unity When removing the rubber string 4 from the tied object a, pull the one string part to release the loop of the knot. The fact that there is only one string passing through the loop, the stretching action of the rubber string, and the unevenness formed on the rubber string 4 It can be easily removed due to the sliding action caused by b, and after it comes out of the loop. In this case, the remaining loops are expanded, and the binding state can be easily released. Moreover, the knot building 43 and the string holder 42 are arranged so that their respective drive axes are parallel to each other. Since the cord holder 42 is provided at The postures of the two string portions to be positioned and the rotating direction of the string holder 42 are approximately parallel to each other. This prevents the clamping spring 42a from being wrapped around the disposed portion and hindering the knotting operation. (Figure 19). Moreover, by forming the streak-like unevenness 4b on the surface of the rubber string 4, the string In the clamping action by the holder 42, it slides appropriately in the longitudinal direction and is clamped appropriately. This means that the holding force can be maintained, and the holding action can be performed smoothly. When the needle retires to the standby position, the string is wound from the guide roller 40. The attachment acts in the direction of loosening, and the rubber cord 4 is paid out from the storage section 5 as the retraction operation is performed. It will be done.
