[Industrial applications]

 The present invention relates to a general-purpose bundling machine for bundling cut flowers, soft vegetables, boxes, etc., and more specifically, a bundling string for a bundling object manually placed and transferred along a workbench. The present invention relates to a general-purpose binding machine having a needle for guiding winding and a binding mechanism for binding a string supplied by the needle.

[0002]

[Prior art]

 Recently, we have rationally improved the discharge straw bundling device used for combine, binder, etc., which is a conventionally well-known mechanism, and perform a bundling operation based on a switch operation using an electrically controlled one-rotation clutch mechanism. A general-purpose binding machine that can bind cut flowers and soft vegetables without damaging them has been put to practical use with a rubber cord, but in the conventional general-purpose binding machine, the workbench was configured to have a flat surface over the entire area. [For example, see Japanese Patent Application No. 3-120733 by the applicant].

[0003]

[Problems to be solved by the device]

 However, when performing string binding of a relatively small box body such as a lunch box using a Styrofoam container using the general-purpose binding machine having the above-mentioned conventional structure, the box body to be bound is manually operated. The work is carried out by transporting it on the workbench while grasping it with a box.However, since the box as described above holds down the upper and lower sides, it is necessary to hold a finger between the bottom of the box and the transfer surface of the workbench. Since the box is lifted from the work table by that amount, the string will loosen when the string binding operation is performed, and it will be difficult to perform the binding work, and there is room for improvement. there were. The present invention aims to solve the above-mentioned problems.

[0004]

[Means for Solving the Problems]

 The characteristic structure of the present invention is, in the general-purpose binding machine described at the beginning, for transferring a bound object placement transfer surface located at a binding action position on the upper surface of the work table and for passing fingers formed along the transfer direction. A mounting guide member having a step recess is detachably attached.

[0005]

[Action]

 For example, when bundling a relatively small box as described above, the box as an object to be bound can be transferred by placing the box on the loading guide member by attaching the above-mentioned loading guide member. Even if the gripping position by hand is relatively close to the binding action position by placing it on the surface and placing the fingers for gripping the box body in the stepped recesses and transferring. When the object to be bound is gripped by hand, there is almost no gap between the bottom surface of the object to be bound and the transfer surface, and it is supplied in a stable posture, with little slack and efficiently The operation can be performed. Also, when binding long and thin objects to be bound, such as cut flowers, a sufficient distance can be secured between the gripping point of the objects to be bound and the binding action position. Even if the object to be bound is to remove and perform work while binding multiple stems together at a place away from the place where it can be gripped by hand, the gap between the stem and the knot formed by the binding mechanism should be minimized. It is possible to reduce the number of wires and to perform binding operation with less string looseness.

[0006]

[Effect of device]

 Therefore, a general-purpose binding machine that can always perform the binding work efficiently and easily according to the type of the object to be bound, and can perform the string binding operation with the least looseness as much as possible. Has come to offer.

【Example】

 Embodiments will be described below with reference to the drawings. 1 to 4 show a general-purpose binding machine for binding a bundled object a such as cut flowers, leeks, and soft and long vegetables such as asparagus using a rubber cord. This binding machine is provided with an electric motor 2 as a drive source and a knotting mechanism 3 inside the box body 1, and a winding cord storage portion 5 in which a binding rubber cord 4 is wound and stored above the outside of the box body 1. And a needle 6 for feeding out the rubber cord 4 from the winding cord storage portion 5 at a high speed and supplying the rubber cord 4 toward the knot mechanism 3, which is to be bound along the upper workbench 7 of the box body 1. A is artificially placed and supplied to perform binding operation. A transmission belt 14 is stretched over a pulley 9 provided on the output shaft 8 of the electric motor 2 and a pulley 13 provided on a relay shaft 12 supported by a bearing member 10 standing from the bottom of the box body 1. , A gear 15 provided on the relay shaft 12 and a large-diameter gear 17 which is fitted onto the driven shaft 16 so as to freely rotate are engaged with each other, and a one-rotation clutch is provided between the large-diameter gear 17 and the driven shaft 16. The mechanism 18 is interposed. A driven crank mechanism 19 for driving the needle 6 is provided at one end of the driven shaft 16 and interlockingly connected to a drive shaft 21 of the knot mechanism 3 via a bevel gear mechanism 20 provided at the other end. It is a branch transmission.

The needle 6 is provided so as to be exposed upward from the workbench 7, and is pivotally supported by a needle support case 28 protruding upward from the workbench 7 so as to be swingable around a horizontal axis X1. . That is, the support boss portion 30 is cantilevered from the needle support case 28, the rotation shaft 29 is provided in the boss portion 30, and the needle 6 is connected to the shaft end. Then, inside the needle support case 28, the drive arm 32 attached to the rotating shaft 29 and the crank mechanism 19 are operatively connected via a push-pull rod 33, and the crank mechanism 19 drives the drive arm 32. That is, the needle 6 is swingably driven within a predetermined range to supply the rubber cord 4 to the knot mechanism 3. Further, the needle 6 is urged to return to the upper standby position by the spring 34 arranged in the needle support case 28, and the elastic force of the rubber string 4 which expands when the one-rotation clutch mechanism 18 is in the disengaged state. Therefore, it is configured so as not to stop at the unstable position displaced downward from the predetermined standby position.

As shown in FIGS. 1 to 3 and 9, the winding cord storage portion 5 rotatably supports a winding cord 36 by a support member 35 extending from the support boss portion 30. A string guide rod 37 and a pair of string guide rollers 39 and 40 are attached to the needle side of the boss portion 30. The pay-out string is wound around the guide roller 40 located on the lower side of the string supply once and then supplied to the needle 6. The string guide hole 37a of the string guide rod 37 is formed as a long hole in the lateral direction, and is set so as not to come into sliding contact with the lateral end portion as the string is unwound so that the unwinding resistance does not change. When the cord is consumed and the outer diameter of the cord is reduced, it is slidably contacted with the upper part to increase the feeding resistance. In addition, a friction brake member 60 that slidably acts on the outer circumferential surface of the winding string 36 by its own weight is swingably supported and arranged. The brake member 60 is made of a square member and has a swing fulcrum set at a position higher than the winding cord 36 so that the braking member 60 always slidably acts on the winding cord 36 in an oblique posture. As shown in FIG. 11, the bundling rubber string 4 has a strip-shaped rubber plate body 4a having a string-like unevenness 4b continuous in the longitudinal direction on the surface of the band-shaped rubber plate body 4a to improve the sliding in the longitudinal direction. It is configured so that an appropriate tension force can be obtained in a state where the objects a are bundled.

The knot mechanism 3 is provided in a knotter bill type, holds and holds one end of the rubber cord 4, and puts a new cord portion supplied by the needle 6 and a cord portion on the held side in an overlapping state. A string holder 42 to be set and a knotting building 43 for knotting by winding both overlapping string portions as described above are provided, and the string holder 42 and the knotting building 43 have their rotation drive axes parallel to each other. Are arranged in this way and supported by a support bracket 44, and a pair of timing gears 45, 46 for driving them are attached to the knot drive shaft 21. Then, at a position near the upper side of the knotted building 43, when the cord winding operation of the knotted building 43 is performed, that is, the rubber cord portion pinched and held by the cord holder 42 and the rubber cord portion after winding the object to be bound. When a cord is wound to form a knot, a string guide member 47 is provided for locking and holding each of the string portions at a predetermined actuated position, and after the string winding operation by the knot building 43 is completed, the needle 6 is used. A moving means A for moving the string guide member 47 in a direction substantially orthogonal to the string supply direction is provided. More specifically, as shown in FIG. 10, the string guide member 47 is provided in the shape of a plate that covers the upper part of the knotted building 43, and both of the string parts are inserted and engaged along the moving direction of the object to be bound a. An engaging recess 48 is formed and is pivotally supported on the support bracket 44 by a swing support arm 49 so as to be swingable around an axis along the axial direction of the knot drive shaft 21. The swing support arm 49 is urged by the spring 50 to swing toward the working posture, and the cam follower 52 is abuttingly engaged with the cam 51 provided on the knot drive shaft 21, so that the working posture and the knot building can be obtained. The moving means A is configured so as to swing and move so as to retract from the upper position. In this way, when the string guide member 47 is switched to the retracted posture while being wound by the knot building 43, the string comes off from the knot building 43 and the knot operation is completed. As shown in FIG. 10, a cutout recess 47a having a shape substantially conforming to the outer shape of the knot building 43 is formed at the lower end of the string guide member 47 in the moving direction. According to this structure, even when a thick rubber cord having a large tension is used, the rubber cord 4 is pulled out while directly handling and handling the cord portion wound around the knot building 43, so that a sufficient knot is formed. There is an advantage that the nodule operation can be performed in this state. The rotation shaft 29 of the needle 6 is arranged so as to be positioned above the center of the rotation axis of the knot building 43 and the rotation axis of the string holder 42, and the rubber string 4 is connected to the knot building 43 and the string. It is supplied to the holder 42 at a substantially uniform level, and the needle support case 28 is provided in an inclined posture so that a large knot space can be secured. In the vicinity of the string guide member 47, there is provided a string pulling member 53 which can be switched between a stop position for closing the entrance part of the locking recess 48 and a position for opening the entrance part, and a string by the knot building 43. Attitude switching means B is provided for switching the string-pulling member 53 to a position that prevents the cord-pulling member 53 from coming off during the winding operation. In other words, as shown in the figure, the cord pulling member 53 is pivotally supported on the support bracket 44 so as to be swingable around an axis X2 orthogonal to the axis of the knot drive shaft 21, and is rocked toward the open position by the spring 54. The cam followers 55 are connected to the cam 56 provided on the knot drive shaft 21 so as to be oscillated and oscillated. Further, between the knot building 43 and the string holder 42, a string inner plate 57 is provided for restricting the rubber string 4 whose one end is held by the string holder 42 to a predetermined standby position when the needle 6 is retracted. The cord guide plate 57 is arranged so as to approach the outer end rotation locus of the cord cutting cutter 58 provided in the cord holder 42 with a minute gap smaller than the thickness of the rubber cord.

As shown in FIGS. 4 and 5, the one-rotation clutch mechanism 18 is provided with a pawl clutch 22 between the boss portion of the large-diameter gear 17 and the driven shaft 16, and the pawl clutch 22 has a pawl clutch 22. The clutch plate 23 is set between the driven-side meshing portion 22a and the driving-side meshing portion 22b by pushing the locking plate 23 from the upper side toward the inner side in the axial radial direction with a pressing force. The clutch plate 23 can be set in the clutch-engaged state by swinging the locking plate 23 in a direction away from the pawl clutch 22 by driving the electromagnetic solenoid 25 via the operating plate 24. Immediately after the clutch is engaged, the electromagnetic solenoid 25 is disengaged and actuated, and when the driven shaft 16 makes one revolution, the locking plate 23 is engaged along the inclined cam surface 26 formed on the outer peripheral surface of the driven side meshing portion 22a. Accordingly, the driven side meshing portion 22a is gradually slid to the clutch disengagement side and is rotationally driven only once. The electromagnetic solenoid 25 is configured to be turned on and off for only a short time by the operation of either the foot switch SW1 or the hand switch SW2 arranged at the foot of the operator. A changeover switch SW3 is provided which can be switched between a state in which the foot switch SW1 is used and a state in which the hand switch SW2 is used. The hand switch SW2 projects the operating piece 27 upward from the work table 7 at the upper hand side position of the knotting mechanism 3 at the passing position when the bundled object a is placed and supplied, and is supplied with the bundled object a. It is configured so that it automatically enters and operates when contacted.

When a small box or the like is to be bound as an object to be bound, the placement guide member 63 is detachably attached to the work table 7 at a position corresponding to the transfer area, and the placement guide member 63 is attached. A vertical positioning contact plate 64 is attached to the inner side of the member 63. As shown in FIG. 23, the placement guide member 63 includes a placement transfer surface 63a on which a bundled object having a needle passage insertion hole 65 is placed and transferred. A stepped recess 63b for passing a finger is formed along the transfer direction, and is configured to be fixed together by a fixing knob bolt 67 of the front operation panel 66. When the boxes are bound, as shown in FIG. 24, when the boxes are moved along the placement transfer surface 63a while being gripped by the hands, the fingers are allowed to enter the stepped recesses 63b so as not to hinder the binding operation. You can work like this. Further, the contact plate 64 is constructed so that its position can be adjusted forward and backward.

Next, a binding operation procedure will be described. The operation procedure is shown in FIGS. The end of the rubber cord 4 is clamped and held by the cord holder 42, and from the standby state in which the needle 6 is in the upper standby position, the object to be bound a is placed on the work table 7 and supplied along the lower side of the cord. Then, when the bound object a approaches the binding action point, the bound object a comes into contact with the operating contact piece 27 of the hand switch SW 2, the switch is actuated, and the one-rotation clutch mechanism 18 is activated. The driven shaft 16 is driven to rotate once. Then, as shown in FIG. 12, the needle 6 operates to supply the rubber cord 4 toward the knot mechanism 3. At this time, the string wound around the string inner roller 40 is wound in the direction in which it is further wound with the operation of the needle 6, and the unwinding of the string is almost stopped. Then, before the needle 6 reaches the maximum plunging position, first, the string-pulling member 53 is switched from the open position to the retaining position. Immediately after that, the knot building 43 is rotationally driven to wind the string portion 4c held by the string holder 42 and the string portion 4d supplied by the needle 6 together to start the knot operation. At this time, the string guide member 47 is set to the working position. After that, when the needle 6 reaches the maximum plunging position, the cord holder 42 rotates from that point to align both the cord portions 4c and 4d and to be wound by the knot building 43. 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 cutting cutter 58 provided in the string holder 42 approaches the string guide plate 57 to cut both string portions. After that, the string guide member 47 swings laterally from the acting state to pull out the string wound around the knot building 43, and the knot operation is completed. At this time, as described above, since the rubber cord 4 is hardly fed out from the needle 6 side, the rubber cord 4 is in the extended state during the knotting operation, and the cord holder 42 is first attached to the cord holder 42 when the cord is cut. Since the string portion 4c that was held and held is in an extremely extended state due to the winding action, when it is cut, it will come off from the knot portion of the knot building 43, and will be bound. The knot becomes a so-called single knot (Fig. 21). As a result, when the rubber cord 4 is detached from the bound object a, if the above-mentioned one cord portion is pulled, it can be easily removed due to the stretching action of the rubber cord and the sliding action due to the unevenness 4b formed on the rubber cord. You can Moreover, since the knot building 43 and the string holder 42 are provided such that the drive shaft cores of the knot building 43 are parallel to each other, when the winding operation of the string holder 42 is performed, the two knots of the two string parts positioned with the knot building 43 are positioned. The posture and the direction of rotation of the string holder 42 are substantially parallel to each other, and the knotting operation is not hindered by being wound around the arrangement portion of the holding spring 42a. Moreover, by forming the stripe-shaped irregularities 4b on the surface of the rubber cord 4, it becomes possible to moderately slide in the longitudinal direction and to maintain an appropriate clamping force in the clamping action by the cord holder 42. The action can be performed smoothly. Then, when the needle is retracted to the standby position, the winding of the cord acts from the guide roller 40 in a loosening direction, and the rubber cord 4 is paid out from the accommodating portion 5 in accordance with the retracting operation.
