Description

  The present invention relates to a filling container reversing device used in a bagging and packaging machine and the like and a filling container used in the device. More specifically, when packaging food or the like in a packaging container such as a packaging bag, the container containing the filling to be filled in the packaging container is inverted from the upright state to the inverted state, and the filling in the container is moved downward. The present invention relates to a filling container reversing device that drops and fills the packaging container disposed in the container, and a container for storing the filling that is suitable for use in the device.

  When automatically packaging food or the like, a container containing a predetermined amount of food or the like to be filled in the packaging container is sequentially supplied, and the container is sandwiched by, for example, a pair of detachable clamping members, and the clamping members are vertically By rotating in a plane, the container is reversed from an upright state, and the filling in the container is dropped into a packaging container disposed below and filled. An example of this type of reversing device is described in, for example, Japanese Utility Model Publication No. 7-20007.

  In the reversing device described in this publication, the container is held by a clamping member attached to the tip of a rotating arm, and the container is reversed from an upright state to an inverted state by rotating the arm approximately 180 degrees, and the reversal thereof Release the container while still accelerating in position. And a container is made to collide with a stopper board etc., and the inside filling is discharged | emitted below by the impact. Therefore, a large impact sound is generated at the time of the collision, which contributes to the deterioration of the working environment. Further, there is a problem that a part of the container is chipped due to an impact at the time of collision, and the chipped part is mixed with the filling material and mixed into the packaging container. (The container is often made of resin.)

  In Japanese Patent No. 2929476, a cushioning material such as rubber is provided at the stopper portion, and although the impact sound is somewhat reduced, it is not yet sufficient. Further, due to repeated collisions, not only the container but also the rubber material of the cushioning material may be worn and mixed into the filling. Furthermore, due to the cushioning action on the cushioning material, in the case of a relatively viscous filling, the discharge of the filling from the container may be incomplete.

  In utility model registration No. 2539246, the arm is stopped at a position rotated 180 degrees, the inertia is used to discharge the filling in the container downward, the container is then released and dropped, and it is stopped against the stopper plate. I am letting. Therefore, although the problem due to impact is alleviated compared to the above two examples, it is not yet a complete solution. Also, if the reversal speed is increased in order to improve the processing capacity and complete discharge of the filling material from the container in this apparatus, the filling material discharged from the container does not fall directly below when the arm is stopped. There is a tendency that the product is discharged in a direction along the rotation trajectory, and therefore, there is a problem that the packing material is not surely filled into the packaging container by adhering to the guide side wall.

  On the other hand, the containers used in the conventional reversing device for filling containers, including the above examples, have smooth outer peripheral surfaces and upper and lower end surfaces with no irregularities. The contact surfaces of the pair of holding members that are in contact with the container are also formed smoothly. Therefore, it is necessary to hold the container with a considerably strong force so that the container does not slip off from the holding member when the container is reversed. In some cases, the filler may adhere to the outer peripheral surface of the container. In particular, when the filler contains an oil component, the magnitude of the clamping force must be set larger. Therefore, the container is severely worn and has poor durability. In addition, there is a possibility that foreign matters generated due to wear may be mixed in the filler.

No. 7-20007 Japanese Patent No. 2929476 Utility Model Registration No. 2539246

  The present invention has been made in view of the above-described conventional problems, and discharges the filling material from the container without causing the filling container to collide with a stopper or the like, thereby preventing generation of noise and realizing a good working environment. In addition, an object of the present invention is to provide a filling container reversing device which avoids breakage of the container and prevents the chipping of the container from being mixed into the filling.

  It is also an object of the present invention to provide a filling container reversing device that can improve the processing capacity regardless of the type, properties, amount, and the like of the filling and can reliably fill the packing container.

  Furthermore, it is an object of the present invention to provide a filling container reversing device that does not require a clamping force as strong as that of the prior art and can improve the wear and durability of the container.

  Another object of the present invention is to provide a filler container that can be suitably used in the above-described filler container inversion device.

  In order to solve the above-mentioned problem, the container containing the filling material to be sequentially supplied according to the present invention is inverted from the upright state to the substantially inverted state, and the filling material in the container is directed to the packaging container disposed below. The filling container reversing device that drops and fills includes reversing means, reversal stop position adjusting means, empty container carrying means, and clamping member opening / closing means.

  The reversing means includes a main rotating member that can rotate around an axis, a rotating means that intermittently rotates the main rotating member in a fixed direction, and stops at first and second positions, and is attached to the rotating means. And a pair of holding members that can hold and hold the container while the holding member is stopped when the main rotating member stops at the first and second positions. Each stops at a holding stop position where the container supplied in the upright state can be held and a reverse stop position where the container is held in a substantially inverted state.

  The reverse stop position adjusting means adjusts the reverse stop position of the clamping member.

  The empty container carry-out means is arranged at an empty container discharge position provided in the middle of returning the holding member from the reverse stop position to the holding stop position, receives the empty container from which the filling material has been discharged, and transports it to a subsequent process. To do.

  The clamping member opening / closing means closes the clamping member at the clamping stop position to clamp the container, opens the clamping member at the empty container discharge position, and discharges the empty container toward the empty container carrying-out means.

  With the above configuration, the container is sandwiched and rotated by the sandwiching member, and the filling in the container is discharged using the inertia force at the reversal stop position where the container is reversed and stopped. Since it is clamped by the clamping member as it is and released toward the container unloading means in the middle of returning to the clamping stop position, there is no direct collision between the container and the stopper plate as in the prior art. The problem of deterioration does not occur.

  In addition, the reverse stop position can be arbitrarily adjusted by the reverse stop position adjusting means, so the reverse stop position is adjusted according to the properties, filling amount, processing speed, etc. of the filling, and the filling surely falls into the packaging container directly below. You can do that.

  In one embodiment, the main rotating member comprises a main rotating shaft that intermittently rotates in one direction by 180 degrees, and the rotating means is further supported by the main rotating shaft in parallel with the main rotating shaft and is self-supporting. Is provided with a support shaft that can reciprocate between an initial position and a rotation position. The filling container reversing device further includes a supporting shaft rotating means for rotating the supporting shaft, the reversing stop position adjusting means adjusts the rotational position of the supporting shaft, and the pair of clamping members are It is attached to one end of the support shaft.

  In the above configuration, the supporting shaft rotating means rotates the supporting shaft to change the relative position in the rotational direction with respect to the main rotating shaft. Even when intermittent rotation is performed gradually, the reverse stop position can be changed while the pinching stop position is kept constant.

  In addition, the spindle is rotated during reversal.By appropriately setting the mode of the rotation, for example, the container is not tilted so much at the initial stage of reversal, and the container is reversed at the end of reversal. The inclination state can be set so that the filling material does not jump out of the container in the middle according to the kind, properties, amount and reversal speed of the filling material.

  In another embodiment, the support shaft is formed in a hollow shape, and the holding member opening and closing device is inserted into the hollow portion of the support shaft so as to be axially movable, and is slid connected to the holding member at one end. The holding member is configured to open and close in conjunction with the axial movement of the sliding shaft.

  According to the above configuration, since the sliding shaft is arranged in the support shaft, the periphery of the reversing mechanism of the apparatus can be made compact, and the cleaning property is improved.

  In still another embodiment, the support shaft rotating means includes a groove cam fixedly arranged around the axis of the main rotation shaft, a lever fixed to the other end of the support shaft, and an attachment to the lever. And a cam roller that rolls in a groove formed in the groove cam, and the groove cam has a groove width within a predetermined range before and after the position corresponding to the rotational position of the support shaft, and at least an inner diameter. The reverse stop position adjusting means is formed to be smaller than the other part of the groove and wider than the diameter of the roller, and the reverse stop position adjusting means includes a stopper that contacts and positions the lever at the reverse stop position, And stopper position adjusting means for adjusting the position.

  According to the above configuration, the reversal stop position can be changed only by adjusting the position of the stopper, and the nipping stop position does not change even if the reversal stop position is changed, so that the adjustment work can be easily performed.

  In still another embodiment, the support shaft is provided symmetrically with the axis of the main rotating shaft as the axis of symmetry, and the pair of clamping members are provided respectively. Thereby, the processing capability of the apparatus can be increased.

  In still another embodiment, the sandwiching member sandwiches the outer peripheral surface of the container, and the outer peripheral surface of the container is formed with ridges or grooves extending in the entire circumferential direction. Grooves or ridges that fit into the convex shape of the container or the groove are formed on the clamping surface facing the container. Thereby, clamping of a container can be performed reliably and a container does not remove | deviate from a clamping member. Therefore, it is not necessary to sandwich the container with an excessively strong force, and damage to the container can be prevented. Furthermore, by making the ridges and grooves into a substantially circular cross section or a trapezoid, the fitting of the ridges and grooves between the container and the clamping member is surely and stable. Moreover, by setting it as the structure which forms a groove | channel on the container side, the container damage by the collision of the protruding ridges which may arise when a protruding ridge is formed in a container can be prevented.

  In yet another embodiment, the rotational speed of the main rotating member changes in at least two stages, and is low during the first movement period in which the clamping member moves from the reverse stop position to the container discharge position. Thereafter, the second movement period during which the movement to the clamping stop position is faster than the first movement period. As a result, it is possible to reliably deliver the empty container to the empty container carrying-out means and to surely discharge the filler.

  The present invention further provides a filler container suitable for use in the above-described filler container inversion apparatus. The container has grooves or ridges formed on the outer peripheral surface thereof extending over the entire circumference.

  In one embodiment, the cross-sectional shape of the groove or ridge is substantially semicircular or trapezoidal.

  As described above, according to the present invention, breakage of the container during use can be prevented, and mixing of foreign substances into the packaging container can be prevented. In addition, the generation of noise can be reduced, and the working environment can be improved. Further, it is possible to prevent the filling material from jumping out from the container in the middle and to surely fall into the packaging container directly below at the reverse position. The adjustment for that can be done easily.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view, partially in section, showing a filling container reversing device 1 (hereinafter simply referred to as “device 1”) according to an embodiment of the present invention, FIG. 2 is a plan sectional view, and FIG. FIG. 4 is a rear view of the main part. In the present embodiment, as will be described later, two sets of mechanisms for holding and reversing the container Y are provided.

  The apparatus 1 includes a machine base 2, a stand 3 is erected on the machine base 2, and a substantially box-shaped frame 4 is fixedly attached thereon. In the frame 4, two vertical wall portions are formed in the vertical direction in the lower portion of the frame 4 in FIG. 2 in parallel up and down and serve as support portions 5 and 6 for the main rotating shaft 7. The main rotating shaft 7 is supported via bearings 8 and 8 arranged at both ends. The main rotating shaft 7 is formed with through holes at symmetrical positions with respect to the center thereof, and the support shafts 9 and 10 are respectively inserted through the bearings 11 arranged at the ends of the main rotating shaft 7. And is rotatably supported. (For convenience of explanation, the first support shaft 9 is shown on the left side in the state shown in FIG. 2 and the second support shaft 10 is shown on the right side, but there is no need for distinction. Or, when it is obvious, it is simply referred to as the support shaft 9 or the support shaft 10.) Since the support shafts 9, 10 and the members attached thereto and the configuration thereof are the same, the support shaft 9 and related members will be mainly described below. Only explained. In the drawing, the support shaft 9 and related members are in a holding stop position where the container Y can be held, and the support shaft 10 and related members are in a reverse stop position which is a position where the container Y is inverted in a substantially inverted state. is there. The container Y is a bottomed cylindrical container in the present embodiment, and is sequentially supplied to the illustrated position by the supply conveyor 71.

  A through hole is formed in the support shaft 9, and a sliding shaft 12 is inserted through the through hole. The sliding shaft 12 can move in the axial direction but cannot rotate. One end side (the lower side in FIG. 2) of the sliding shaft 12 protrudes from the support shaft 9, and the protruding portion has a holding member support block 13 fixed to a flange portion 9 a formed at the end of the support shaft 9. The cylindrical part 14 formed in the base part of is fitted. The support block 13 includes a bifurcated portion 15, and a left clamping member 16 and a right clamping member 17 that rotate integrally with the fulcrum shafts 16 a and 17 a are attached to the distal ends thereof.

  A link connecting member 18 is fixedly attached to an end portion of the sliding shaft 12 protruding from the cylindrical portion 14 of the holding member support block 13. One end of a link 18a is rotatably attached to the connecting member 18 on the lower surface side of the cylindrical portion 14 (see the second support shaft 10 side in FIG. 2), and the right clamping member 17 is connected to the other end of the link 18a. The end portions of the connecting arm portion 17b are rotatably connected. An engagement pin 19 is planted in the engagement arm portion 17c formed to extend in a direction substantially orthogonal to the connection arm portion 17b of the right clamping member 17, and is formed on the engagement arm portion 16b of the left clamping member 16. A long hole 16c is fitted, and motion is transmitted between the holding members 16 and 17.

  A spring receiving portion 12a having a large diameter is formed in a portion of the sliding shaft 12 located in the cylindrical portion 14 of the holding member support block 13, and the receiving portion 12a and the inner surface of the end of the cylindrical portion 14 of the support block 13 are formed. A compression spring 20 is disposed therebetween. Accordingly, the left and right clamping members 16 and 17 are biased in the closing direction.

  A roller 21 is attached to the opposite end of the sliding shaft 12 via an attachment shaft 22. A clamping member opening / closing cam 25 fixed to and attached to the tip of the rod of the air cylinder 24 attached to the frame 4 via the attachment bracket 23 is disposed on the roller 21. The opening / closing cam 25 is a substantially semi-annular member (see FIG. 4), and the surface facing the roller 21 has a flat portion 25a and an inclined portion 25b inclined toward the end away from the roller 21. (See FIGS. 2 and 4, the roller 21 on the first support shaft 9 side is mounted on the flat portion 25 a in the state shown in the figure, and the roller 21 on the second support shaft 10 side is disengaged from the cam 25. ). When the main rotating shaft 7 is stopped and the first support shaft 9 and its sliding shaft 12 are at the position shown in FIG. 2, the air cylinder 24 is operated to retract the rod, and the cam 25 is retracted. The members 16 and 17 are closed to sandwich the container Y. When the main rotating shaft starts to rotate (in this embodiment, it rotates clockwise in FIG. 1 and counterclockwise in FIG. 4), and the roller 21 on the first support shaft 9 side is disengaged from the cam 25, the air cylinder 4 operates in the opposite direction, returning the cam to its original position. Then, as will be described later, after the main rotating shaft 7 stops at the reverse stop position where the container Y is reversed (the second support shaft 10 is at that position in the drawing), the same direction is required to return to the clamping stop position. When the rotation is resumed, the roller 21 is placed on the inclined portion 25b of the cam 25 and then placed on the flat end portion 25a, and the clamping members 16 and 17 are opened again. This will be described later again.

  Here, with reference to FIG. 7, it demonstrates about the structure of the clamping surface of the container Y and the clamping members 16 and 17. FIG. That is, the container Y does not have a smooth outer peripheral surface as in a conventional container, and a groove Ya having a substantially semicircular cross section extending in the circumferential direction is formed on the outer peripheral surface as shown in FIG. Correspondingly, projections 16d and 17d having a thin strip-like cross section and a semicircular cross section are formed on the inner surfaces of the holding members 16 and 17 for holding the container Y. When the container Y is sandwiched between the sandwiching members 16 and 17, the protrusions 16d and 17d are fitted in the groove Ya, so that the container can be securely sandwiched as compared with the conventional container, and the container is detached from the sandwiching member. There is no. Therefore, it is not necessary to sandwich the container Y with an excessive force. The shape of the groove and the protrusion is not limited to this semicircular shape. For example, as shown in FIG. Further, a protrusion may be formed on the container side and a groove may be formed on the holding member side. In the present embodiment, the groove Ya is formed below the middle in the height direction of the container.

  Next, a mechanism for reversing the container Y will be described with reference mainly to FIGS. 1 to 4 again. Reference numeral 31 denotes a motor attached to the main rotating shaft support 6 of the frame 4 (see FIG. 2). An output shaft 32 of the motor 31 extends through the support portion 6, and a drive gear 33 located between the support portions 5 and 6 is fixed to the tip of the output shaft 32. The drive gear 33 meshes with the driven gear 34 fixed to the main rotation shaft 7 described above. In the present embodiment, the motor 31 rotates intermittently in the same direction, and rotates the main rotating shaft 7 by 180 degrees clockwise in FIG. 1 and counterclockwise in FIG. At this time, the support shafts 9 and 10 also revolve around the axis of the main rotary shaft 7 together.

  2, cam levers 35 are fixedly attached to the end portions of the support shafts 9 and 10 protruding upward from the main rotary shaft 7 (see FIG. 4). A cam roller 36 is attached to the other end. A groove cam 37 corresponding to these cam rollers 36 is fixed to the main rotating shaft support 6. The groove cam 37 is formed with a groove 38 in which the cam roller 36 fits and rolls. The inner wall 39 and the outer wall 40 of the groove 38 are concentric circles centered on the axis of the main rotating shaft 7, and the width of the groove 38 at that portion is approximately the size corresponding to the diameter of the cam roller 36. It consists of a uniform portion 38a and a part of the enlarged portion 38b having a larger width. That is, the inner side wall 39 includes a concentric circular portion 39a and a displacement portion 39b that gradually decreases in diameter and gradually increases in the counterclockwise direction from the upper left side to the lower side in FIG. In addition, the outer wall 40 includes a concentric circular portion 40a and a displacement portion 40b that gradually increases in diameter on the upper side and decreases again. Therefore, while the cam roller 36 is positioned at the uniform portion 38a, the support shafts 9 and 10 cannot rotate, but the enlarged portion 38b can do so.

  In FIG. 4, the cam lever 35 attached to the second support shaft 10 is attached to the cam lever 35, and thus to the second support shaft 10 side, corresponding to the end of the cam lever 36 attached to the cam roller 36. A stopper mechanism 45 is provided for adjusting the stop position of the holding members 16 and 17, that is, the reverse stop position.

  Referring to FIGS. 5 and 6 in addition to FIG. 4, FIG. 5 is a plan view showing details of the stopper mechanism 45, and FIG. 6 is a right side view thereof. Reference numeral 46 denotes a rail of the stopper mechanism 45, which is fixed to the main rotating shaft support portion 6 of the frame 4. A slide member 47 is attached to the rail 46 so as to be movable in the left-right direction in FIGS. A slide plate 48 is integrally fixed on the slide member 47, and a stopper roller 50 is attached to the slide plate 48 by a support shaft 49 at the left end portion in FIG. An abutting portion 51 that abuts is erected. On the other hand, a shock absorber 52 is attached to the main rotary shaft support portion 6 via a mounting bracket 54 in correspondence with the contact portion 51. The contact portion 51 of the slide plate 48 contacts the contact shaft 53. The position of the shock absorber 52 can be adjusted in the axial direction of the contact shaft 53.

  When the main rotating shaft 7 starts to rotate from the state shown in FIG. 1 and the like, the first support shaft 9 is initially configured so that the cam roller 36 on the cam lever 35 attached thereto has the width of the groove 38 of the groove cam 37. Since the uniform portion rolls, it cannot rotate, and only rotates (revolves) around the axis of the main rotating shaft 7 integrally with the main rotating shaft 7. When the cam roller 36 reaches the displacement portion 40b of the outer wall 40 of the groove 38 and further the displacement portion 39b of the inner wall, the width of the groove 38 becomes larger than the diameter of the cam roller 36. Therefore, the cam roller 36 moves in a rolling manner on the inner wall 39b, and the cam lever 35 and the support shaft 9 rotate around the axis in the clockwise direction in FIG. In other words, the cam lever 35 and the clamping members 16 and 17 attached thereto rotate in a state of being slightly delayed with respect to the main rotating shaft 7. When the main rotating shaft 7 is rotated by 180 degrees and stopped, the cam members 35 and the support shaft 9 are rotated in the counterclockwise direction by continuing the movement of the clamping members 16 and 17 as they are due to inertia. The end of the cam lever 35 on the side where the cam roller 36 is attached collides with the stopper roller 50 described above, and the impact is absorbed by the shock absorber 52, while the cam lever 35 and thus the support shaft 9 stop. The second spindle 10 and the members attached thereto in FIGS. 1 to 4 correspond to this state. At this time, the container Y suddenly stops in a substantially inverted state as shown in FIG. 1 and discharges the filled material into the lower guide tube 56. At this time, as shown in the drawing, the container Y is not completely inverted. This is in consideration of the direction in which the filling in the container Y, which is referred to in the description of the prior art, is discharged when the container Y is suddenly stopped. This discharge direction can be optimally adjusted by adjusting the position of the shock absorber 52 of the stopper mechanism 45 described above to adjust the final stop position, that is, the reverse stop position of the clamping members 16 and 17.

  Next, at a predetermined timing, the main rotation shaft 7 resumes rotating in the same direction again, and the second support shaft 10 in the reverse stop position in the drawing is stopped by the above-mentioned clamping where the first support shaft 9 is positioned. The operation to return to the position is started. As the main rotary shaft 7 rotates, the support shaft 10 rotates together with the main rotary shaft 7 while the cam lever 35 first pushes the shock absorber 52 via the stopper roller 50, and the cam lever 35 moves to the stopper roller 50. To disengage. Then, the cam roller 36 rolls on a portion where the diameter of the displacement portion 39b of the inner wall 39 of the groove 38 of the groove cam 37 gradually increases, so that the support shaft 10 rotates by a predetermined angle in the opposite direction to the previous direction. And the main rotary shaft 7 return to their original state.

  On the other hand, when the main rotating shaft 7 rotates in the returning step, the roller 21 attached to the sliding shaft 12 is also placed on the inclined portion 25b of the holding member opening / closing cam 25, and then at a predetermined rotational position. It rides on the flat part 25a, opens the clamping members 16 and 17, and discharges the held container Y. This position is a container discharge position, in which a container unloading device 61 that receives an empty container Y and transports it to a subsequent process is disposed (see FIGS. 1 and 3). The operation of discharging the container Y is performed while the main rotating shaft 7 continues to rotate.

  The container carry-out device 61 includes an empty container collection conveyor 62, and the space between the receiving end and a notch 56a through which the container Y sandwiched between the sandwiching members 16 and 17 formed on the guide tube 56 can pass. A container collection guide 63 extending to the stand 3 is attached to the stand 3 by a bracket 64. The empty container Y released when the holding members 16 and 17 are opened is received on the empty container collection guide 63, moved onto the conveyor 62, and conveyed to the subsequent process while being guided by the guide rod 65. The main rotating shaft 7 continues to rotate, rotates 180 degrees and stops, and the clamping members 16 and 17 return to the clamping stop position in the open state.

  In the present embodiment, the rotational speed of the motor 31 is changed in two steps during one operation. That is, since there is a problem in discharging the empty container Y at a too high speed, the stage until the discharge is completed is set to a relatively low speed, and the speed is changed to a high speed after the discharge. The filling material is discharged completely from the container Y.

  In the above embodiment, two support shafts are provided on the main rotating shaft and two sets of clamping members are used. However, when using one set of clamping members, the clamping members are directly attached to the main rotating shaft. Can be. At that time, if the servo motor is used as the motor and thereby the rotation angle from the pinching stop position to the reverse stop position and the return rotation angle from the reverse stop position to the pinching stop position are adjusted appropriately, the above-mentioned It is not necessary to use the stopper mechanism used in the embodiment.
