Definitions
- the present invention relates to a cap application and tightening apparatus for a trigger pump vessel used in a material filling and packing industry and the like.
- This type of the vessel member includes the above cap 4 rotatably attached to a pump 5 faced to a horizontal direction and the pump 5 includes a suction hose 6 provided on the lower side, i.e., on the liquid suction side thereof and a nozzle 7 faced to a predetermined direction and provided on the lower side, i.e., the liquid spray side thereof and further a trigger portion 8 to be pressed by a finger of a hand holding the above pump 5.
- the nozzle 7 projecting upwardly from the vessel 1 through the above cap 4 must be arranged to a predetermined uniform direction with respect to a label la attached on the front surface of the vessel, taking the decorative effect thereof into consideration when the vessel is displayed in a shop.
- a job for filling a liquid such as detergent or the like into the vessel and packing the same is automatically carried out as a trial by an apparatus having a continuous processes, which is disclosed, for example, in Japanese Patent Application (Laid-Open) Sho 63-67294 for a combination type capper.
- the above conventional combination type capper has the following problems.
- a funnel-shaped guide means is provided at the upper portion of the mouth of a vessel to properly and smoothly insert a suction hose on the liquid suction side of a pump attached to a cap into the mouth of a vessel to thereby cause the lower end of the above suction hose to be guided along the inner inclined surface of the guide means.
- suction hoses are differently curved and a largely curved hose as shown by an imaginary line of Figure 3 sometimes cannot put the extreme end thereof into the opening of the above guide means, and in this case a vessel with this hose is rejected because a cap with nozzle is not properly attached to the vessel.
- the conventional combination type capper is arranged as a roller type capper in which a roller in abutment on the periphery of a cap transmits the rotating force thereof to the cap for tightening the same, the roller comes into contact with the cap through points or a line of the roller, so that the roller is in contact with the cap through a small area and thus a sufficient tightening torque necessary for finally tightening the cap cannot be obtained.
- the above roller must have a large diameter to provide a rotating torque for tightening, but since a cap to be rotated has a small diameter, a sufficient distance cannot be provided between rollers disposed in parallel. Further, although not shown, in the case of a vessel with a projection for positioning a pump and preventing the rotation thereof, the periphery of the above roller abuts against the projection to prevent the vessel from being gripped, and thus a roller to be used must have a small diameter and as a result a torque produced by the roller of small diameter is further reduced.
- An object of the present invention made for satisfying the above desire is to provide a cap application and tightening apparatus for a trigger pump vessel capable of securely, automatically and continuously supplying caps with nozzle to vessels filled with a material, e,g, a liquid, with the extreme end of the hose of the cap securely corresponding to the mouse of each vessel in the state that each vessel corresponds to the cap with nozzle in a predetermined positional relationship and tightening the caps with a predetermined torque.
- a material e,g, a liquid
- a vessel 1 used in this embodiment of the present invention is made of a synthetic resin and formed to an oval shape as shown in Figure 3 or a round shape as shown in Figure 5 having a mouth squeezed to a small diameter and provided with a male screw.
- a recessed portion 2 is defined to the outside surface of the bottom thereof for positioning a printed surface 1a applied to the surface of the vessel, the vessel 1 is filled with a liquid such as detergent or the like and packed, and a cap 4 with a male screw defined around the inside periphery thereof is threaded to the male screw of the mouth.
- the cap 4 is rotatably attached to a cylindrical pump 5 in a horizontal direction, a hose 6 having a length abutting against the bottom of the above vessel 1 is provided on the lower portion , i.e., the suction side of the pump 5 to suck the above liquid, a nozzle 7 facing to one side, i.e., one lateral direction is provided on the upper portion, i.e., the liquid ejection side of the above pump 5, and further a trigger portion 8 to be pressed by a finger of a hand holding the above pump 5.

Description
- The present invention relates to a cap application and tightening apparatus for a trigger pump vessel used in a material filling and packing industry and the like.
- Today, available in a market are many vessel members used for spraying a foamed or atomized liquid of detergent or the like to a surface to be washed due to an eminent progress in a packing vessel member, the vessel member being composed of a
vessel 1 containing a liquid and acap 4 with a trigger pump type nozzle, as shown in Figure 3. - This type of the vessel member includes the
above cap 4 rotatably attached to apump 5 faced to a horizontal direction and thepump 5 includes asuction hose 6 provided on the lower side, i.e., on the liquid suction side thereof and anozzle 7 faced to a predetermined direction and provided on the lower side, i.e., the liquid spray side thereof and further atrigger portion 8 to be pressed by a finger of a hand holding theabove pump 5. - In addition, the
nozzle 7 projecting upwardly from thevessel 1 through theabove cap 4 must be arranged to a predetermined uniform direction with respect to a label la attached on the front surface of the vessel, taking the decorative effect thereof into consideration when the vessel is displayed in a shop. - A job for filling a liquid such as detergent or the like into the vessel and packing the same is automatically carried out as a trial by an apparatus having a continuous processes, which is disclosed, for example, in Japanese Patent Application (Laid-Open) Sho 63-67294 for a combination type capper.
- The above conventional combination type capper has the following problems.
- A funnel-shaped guide means is provided at the upper portion of the mouth of a vessel to properly and smoothly insert a suction hose on the liquid suction side of a pump attached to a cap into the mouth of a vessel to thereby cause the lower end of the above suction hose to be guided along the inner inclined surface of the guide means.
- The above suction hoses, however, are differently curved and a largely curved hose as shown by an imaginary line of Figure 3 sometimes cannot put the extreme end thereof into the opening of the above guide means, and in this case a vessel with this hose is rejected because a cap with nozzle is not properly attached to the vessel.
- Since the conventional combination type capper is arranged as a roller type capper in which a roller in abutment on the periphery of a cap transmits the rotating force thereof to the cap for tightening the same, the roller comes into contact with the cap through points or a line of the roller, so that the roller is in contact with the cap through a small area and thus a sufficient tightening torque necessary for finally tightening the cap cannot be obtained.
- Further, the above roller must have a large diameter to provide a rotating torque for tightening, but since a cap to be rotated has a small diameter, a sufficient distance cannot be provided between rollers disposed in parallel. Further, although not shown, in the case of a vessel with a projection for positioning a pump and preventing the rotation thereof, the periphery of the above roller abuts against the projection to prevent the vessel from being gripped, and thus a roller to be used must have a small diameter and as a result a torque produced by the roller of small diameter is further reduced.
- An object of the present invention made for satisfying the above desire is to provide a cap application and tightening apparatus for a trigger pump vessel capable of securely, automatically and continuously supplying caps with nozzle to vessels filled with a material, e,g, a liquid, with the extreme end of the hose of the cap securely corresponding to the mouse of each vessel in the state that each vessel corresponds to the cap with nozzle in a predetermined positional relationship and tightening the caps with a predetermined torque.
- Further, according to the present invention, since a series of jobs from the application of caps to the tightening thereof are continuously carried out, these jobs can be automatically performed to improve a manufacturing efficiency as well as a factory automation can be achieved to cope of the shortage of manpower.
- When caps are tightened by a machine, a stable tightening torque can be uniformly applied and thus the occurrence of products rejected due to untightened caps or insufficient tightening torque can be entirely prevented to improve a yield.
- Even if the hose of a cap to be inserted into the opening at the mouth of a vessel is largely curved, since the hose is corrected to a vertical state and maintained in this attitude by a locking means provided with a mounting apparatus, the occurrence of vessels rejected by the reason that they have an incorrectly inserted hose or no cap and thus no hose inserted thereinto can be prevented and as a result only good products pass through a series of these systems to achieve a high yield.
- Since a belt used as a tightening means of a tightening unit abuts against the periphery of a cap to be tightened through a contact surface as large as possible, a sufficient tightening torque can be obtained and thus an eminent effect can be achieved in that a ratio of products rejected by the reason that caps are insufficiently tightened due to slip and the like can be greatly lowered, and the like.

- Next, an embodiment of a cap application and tightening apparatus for a trigger pump vessel according to the present invention will be described with reference to the drawings.
- A
vessel 1 used in this embodiment of the present invention is made of a synthetic resin and formed to an oval shape as shown in Figure 3 or a round shape as shown in Figure 5 having a mouth squeezed to a small diameter and provided with a male screw. - In the case of the
round vessel 1, arecessed portion 2 is defined to the outside surface of the bottom thereof for positioning a printed surface 1a applied to the surface of the vessel, thevessel 1 is filled with a liquid such as detergent or the like and packed, and acap 4 with a male screw defined around the inside periphery thereof is threaded to the male screw of the mouth. - The
cap 4 is rotatably attached to acylindrical pump 5 in a horizontal direction, ahose 6 having a length abutting against the bottom of theabove vessel 1 is provided on the lower portion , i.e., the suction side of thepump 5 to suck the above liquid, anozzle 7 facing to one side, i.e., one lateral direction is provided on the upper portion, i.e., the liquid ejection side of theabove pump 5, and further atrigger portion 8 to be pressed by a finger of a hand holding theabove pump 5. As a result, when thistrigger portion 8 is depressed, foamed or atomized detergent or the like is sprayed to a surface to be washed. - In Figures 1 and 2, 9 designates a cap application and tightening apparatus as a whole which is composed of a transfer unit A for transferring the
vessel 1, first cap arrangement unit B1, second cap arrangement unit B2, vessel delivery unit C, cap delivery unit D, mounting unit E for mounting thevessel 1 andcap 4 with nozzle, tightening unit F, transfer unit G for transferring thevessel 1 with thecap 4, and drive means H associated with the above respective units. - The transfer unit A for the
vessel 1 is composed of a horizontal endless conveyer attached to asupport frame plate 10a provided along the entire length of a side of amachine body 10, and theabove vessels 1 filled with a predetermined amount of detergent are placed thereon and continuously transferred to the vessel delivery unit C, the endless conveyer being driven in one direction by a drive means 11 such as a motor with reduction gear or the like. - Note although this transfer unit A is also used as the transfer unit G for discharging the
vessel 1 having been tightened, these transfer operations may be carried out by independent units A and G (not shown). - The first arrangement unit B1 accommodating a multiplicity of the
above caps 2 with nozzle therein is disposed in the vicinity of theabove machine body 10 is used to arrange the direction of thecaps 2, i.e. thecaps 2 andhoses 6 in a predetermined direction. More specifically, as shown in Figure 6, acylindrical cabinet 13 inclined by about 20 to 30o is supported by asupport member 12 and the height thereof can be adjusted by a vertically movingmember 14 contained in thesupport member 12. - A combing-up
disk 16 is rotatably supported in thecabinet 13 by asupport shaft 15 in accordance with the inclination of thecabinet 15 and the combing-updisk 16 is continuously rotated in a direction by adrive means 17 such as a motor or the like with reduction gear coupled to thesupport shaft 15. - Further, a multiplicity of
radial cutouts 18 are intermittently defined around the periphery of the above combing-updisk 16 and cleaning-outplates 19 freely projecting from and entering into thecutouts 18 are mounted on the backside of the above combing-updisk 16 in such a manner that each of the cleaning-outplates 19 is urged by anelastic member 20 such as a leaf spring or the like in a direction along which the cleaning-outplate 19 is embedded below theabove cutout 18. - Then, a
guide 21 is provided in abutment against the lower edge of each of the cleaning-outplates 19 for regulating the embedding of the cleaning-outplate 19, and when the above combing-updisk 16 is moved along an ascending inclination as it is rotated, the cleaning-outplates 19 are projected from the above combing-updisk 16 so that thecaps 4 with nozzle staying at the lower portion of thecabinet 13 are combed up by the above cleaning-out plates and transferred to the upper portion thereof. The thus combed up caps are engaged with thesteps 22 defined around the peripheral edge of the combing-updisk 16 at the lower edges thereof and thus prevented from being dropped when the bombing-updisk 16 is moved upward and further the projected cleaning-outplates 19 prevent the caps withnozzle 4 from moving laterally. - In addition, when the above bombing-up
disk 16 is in a downward process from an upper position, the cleaning-outplates 19 are embedded below thecutouts 18 by the returning force of theelastic members 20, and thus the lateral movement of the caps withnozzle 4 is not prevented. - Designated at 23 is a sweeping-down means provided at the inside upper portion of the
above cabinet 13 and arranged such thatrotating shafts drive motor 25 supported by a mountingplate 24 to the opposite side thereof and a multiplicity offeather members 27 are attached to therotating shafts caps 4 with nozzle are not properly accommodated in the cleaning-outplates cabinet 13, thecaps 4 are swept down by theabove feather members 27 rotating downward at the risen top the of the above combing-updisk 16 toward the bottom portion of thecabinet 13 and then transferred again upward by being accommodated in the cleaning-outplates - Designated at 28 is an outlet tangentially defined in the interior of the
above cabinet 13 in the descending inclination of the above combing-updisk 16 for sending out theabove caps 4 with nozzle arranged on the above combing-upplate 16 to the outside. - The second cap arrangement means B2 disposed in the midway of a
chute 42 coupled to theoutlet 28 of the above first cap arrangement means B1 is used to arrange thenozzle 7 of theabove cap 4 in a predetermined direction. As shown in Figures 10 and 11, when thehose 6 supported by afirst receiving piece 42a and thepump portion 5 supported by asecond receiving piece 42b are transferred in theabove chute 42 in a fallen down state, thepump portion 5 is turned as theabove receiving piece 42b is inclined downward and thus thenozzle portion 7 having a large weight difference is arranged downward, and in this state the attitude of thecap 4 with nozzle is gradually raised up by the bending of theabove chute 42 so that thecap 4 is corrected to be positioned at an upper portion and thehose 6 is corrected to be positioned at a lower portion. - The above vessel receiving unit C continuously supplies the
vessels 1 on the transfer unit A to the mounting unit E through a first transit means 29 one by one, and is arranged such that asupport frame 30 is attached to thesupport frame plate 10a on the transfer unit A in themachine body 10 and atransfer screw 31 is rotatably attached to thesupport frame 30 by being supported by ashaft 32. An end of theshaft 32 is coupled to a rotation means 41 composed of achain wheel 35 attached to adirection changing shaft 34 associated with a direction changing shaft 33, agear 37 meshed with asynchronizing gear 36 of the above drive means H, and achain 40 trained around achain wheel 39 mounted on theshaft 38 of thegear 37. - The cap delivery unit D is interposed between the
outlet 42c of the second cap arrangement unit B2 and the mounting unit E and supplies thecap 4 with nozzle to the mounting unit E, and as shown in Figures 13 and 15, the cap delivery unit D is arranged such that a channel-shapedchute 42 having a predetermined inclination for holding thepump portion 5 of theabove cap 4 with nozzle on the opposite sides thereof is attached to the above outlet 42C. The end of thechute 42 is formed to a flat shape and astopper 44 advanced and retracted by afluid cylinder 43 is provided at the terminal end thereof in such a manner that it is perpendicular to thechute 42. When theabove stopper 44 is released, the caps with nozzle are supplied one by one by asupply member 45 disposed below theabove chute 42 in correspondence with the location of thestopper 44 and ejecting air for blowing off the caps. - As shown in Figure 13, a disk-shaped transfer means 49 with
transfer cutouts 48 is horizontally and rotatably supported between the above end and the above mounting unit E and transfers the above suppliedcaps 4 with nozzle to the gripping member of the mounting unit E through thecutouts 48 along aguide 47 with asemi-annular groove 46, as the transfer means 49 is rotated. Thenozzle 7 is faced to a predetermined direction at all times in such a manner that the arc-shapedcutout 48a of theabove cutout 48 is engaged with the cylindrical portion of thecap 4 and the laterallylong cutout 48b thereof is engaged with thetripper portion 8 of thepump 5. - The above first transit means 29 interposed between the vessel delivery unit C and the mounting unit E supplies the
vessels 1 to the mounting unit E one by one. As show in Figure 2, since the first transit means 29 is arranged such that a horizontal rotatingmember 50 is rotatably supported on themachine body 10 by ashaft 51 and a multiplicity ofcutouts 52, e.g., six sets ofcutouts 52 corresponding to the outside configuration of theabove vessel 1 are defined around the periphery of the rotatingmember 50, and thus thevessel 1 engaged with thecutout 52 is transferred from the vessel delivery unit C to the mounting unit E along an arc-shapedguide 52a as the rotatingmember 50 is rotated. - Note, when the
vessel 1 to be used has a round or square shape, a multiplicity of, e.g., six sets of not shown grip means composed of a pair of radially openable and closable rotating claws are attached to the above rotatingmember 50 in place of the rotatingmember 50, so that thevessel 1 is transferred from the vessel delivery unit C to the mounting unit E by being gripped thereby. - The mounting unit E receives the
vessel 1 transferred from the above first transit means 29 and thecap 4 with nozzle transferred from the above cap delivery unit D and assembles them on the mounting unit E. As shown in Figures 15 and 16, the mounting unit E is arranged such that ahorizontal disk 53 the upper surface of which is in coincidence with the above rotatingmember 50 is rotatably sup ported by ashaft 54 on themachine body 10 and a multiplicity of, e.g., eight sets of grip means 55 for gripping thevessel 1 are radially attached to thehorizontal disk 53 and thus locations corresponding to the grip means 55 of thehorizontal disk 53 are used as placinglocations 56. - As shown in Figures 15, 16, 20 and 21, each of the grip means 55 is composed of a pair of
rotating claws claws horizontal disk 53 byshafts gears shafts vessel 1. Usually, the turningclaws tension spring 60 attached to one of the synchronizing gears 59. - Further, as shown in Figure 16, the
grip member 55 is continuously opened and closed along a moving locus of acam plate 61 in such an arrangement that one of theabove shafts 58 is provided with aroller 62 abutting against thecam plate 61 attached to the aboverotating shaft 54. - Note that 55a and 55b in Figures 20 and 21 designate a grip means used for gripping a round or square vessel, wherein the grip means 55a is arranged such that
grip rollers above vessel 1 is supported on the upper portion of the pair ofrotating claws grip roller vessel 1 are disposed on the lower portion of therotating claws rotating claws horizontal disk 53, and are freely opened and closed by an arrangement similar to that of the turningclaws oval vessel 1. - In the case of the
above round vessel 1, a positioning means 66 is provided with the mounting unit E to rotate therespective vessels 1 so that the direction of the surface thereof is corrected, i.e., the printed surface of thevessels 1 is faced to a predetermined direction. As shown in Figures 16 and 17, thevessel 1 is rotated on theabove placing location 56 in such a manner that eachpositioning plate 68 is engaged with each steppedround hole 67 provided with the abovehorizontal disk 53, a turningmember 71 is supported by a rotatingshaft 70 supported by a bearing 69 of thehorizontal disk 53, and a projectingrod 73 projected upward by aspring 72 is locked to the turningmember 71 through a passinghole 74 defined to a suitable location of theabove positioning plate 68 and engaged with the recessedportion 2 of thevessel 1. - A range in which the
vessel 1 is rotated by the positioning means 66 is intermittently controlled by a control means 75 to be described below. - The control means 75 for controlling the rotation and upward and downward movement of the above
rotating shaft 70 is arranged such that agear 88 meshed with alarge gear 87 fixed to themachine body 10 is attached to the aboverotating shaft 70 through afrction clutch 89, adisk 91 having acutout 90 defined at a suitable location of the periphery thereof is attached to therotating shaft 70, and further a bell crank 95 having aroller 93 engaged with acam 92 and supported by a shaft 94 at an end of the bell crank 95is supported in the vicinity of therotating shaft 70, and when an engagingmember 96 supported at the other end of the bell crank 95 is engaged with theabove cutout 90, the transmission of rotation to the aboverotating shaft 70 is stopped by theabove friction clutch 89. - Note that the above bell crank 95 is urged by a
compressed spring 97 in the direction causing the engagingmember 96 to be always engaged with thecutout 90. - Further, the above projecting
rod 73 of the turningmember 71 attached to the upper end of therotating shaft 70 is freely moved upward and downward through the passinghole 74 defined to theabove positioning plate 68 by the control means 75 in such an arrangement that anannular member 99 having a receiving groove 98 defined around the periphery thereof is attached to the lower end of the aboverotating shaft 70, aroller 103, with which the engagingmember 101 of anarm 100 attached to the shaft 94 of the above bell crank 95 and to which the shaft 102of the engagingmember 101 is connected, is abutted against a cam provided around the aboverotating shaft 54 and the aboverotating shaft 70 is moved upward and downward as the circular motion of thecam 104 is changed into motion up and down. - Note that the above
rotating shaft 70 is vertically floatingly supported by acompressed spring 105 accommodated in theabove bearing 69 and urged upward at all times. - A cap supply means 106 in the above mounting unit E is composed of a vertically moving
means 108 for thecap 4 with nozzle and a suspension means 109 therefore. The vertically movingmeans 108 supports thepump 5 of thecap 4 with nozzle supplied from the cap delivery unit D so that thecap 4 is correctly mounted to thevessel 1 supplied onto the placinglocation 56 of the above mounting unit E. As shown in Figure 15, a cylindrical member 111 having acam groove 110 defined thereto is attached to theabove machine body 10 and a vertically movingrod 113 supported by the upper mountingplate 112 of the aboverotating shaft 54 at one end thereof is attached to thecam groove 110 of the cylindrical member 111 through a movingmember 114 at the other end thereof, and thus when the above cylindrical member 111 is rotated, the vertically movingrod 113 is moved upward and downward while the movingmember 114 slides along theabove groove 110. - The above suspension means 109 is opened and closed by an actuation means 115 such as a fluid cylinder or the like attached to the lower end of the above vertically moving
rod 113 and provided with a pair ofclaw members 116 for gripping thepump portion 5 of theabove cap 4 supplied from the cap delivery unit D. - Further, since the mounting unit E is provided with a locking means 117 for smoothly and securely inserting the
hose 6 of thecap 4 held by the above suspension means 109 into thevessel 1, and as shown in Figure 15, each of movingpieces 121 is engaged with each of a pair ofspline shafts upper mounting plate 112 of the aboverotating shaft 54 and thelower mounting plate 118 attached to therotating shaft 54, each of vertically movingmembers 122 such as a rodless cylinder or the like attached to a mountingmember 118a is associated with each of the movingpieces 121, and each ofgrip claws pieces 121 is slidingly attached to each of theabove spline shafts - A
rotating lever 125 is supported at the upper end of one of the pair ofabove spline shafts roller 127 abutting against thecam plate 126 attached to the lower portion of the above cylindrical member 111 is supported at the extreme end of thelever 125, and thus when a positional change caused by a rotational force of thecam 126 is transmitted to the pair ofabove spline shafts rotating lever 125 and synchronizinggears above claws hose 6 of thecap 4 with nozzle is greatly bent as shown by a two-dot-and-dash line in Figure 3, thehose 6 is maintained vertically by being supported by thegrip claws grip claws cap 4 to grip thehose 6 and thegrip claws above hose 6 can be securely inserted into thevessel 1 through the opening at the mouse thereof waiting on the placinglocation 56 of thehorizontal disk 54 by actuating the above vertically movingmeans 108. - In Figure 2, 130 designates a second transit means for supplying the
vessel 1 on which thecap 4 with nozzle is mounted in the mounting unit E to the tightening unit F to be described below. Since the second transit means 130 is arranged similarly to that of the above first transit means 29, it is not described here in detail. - The above tightening unit F receives the
vessel 1 supplied from the above second transit means 130 and tightens thecap 4 to the mouse of thevessel 1. As shown in Figure 25, the tightening unit F is arranged such that the abovehorizontal plate 53 and arotating disk 131 the upper surface of which is in coincidence therewith are rotatably supported on themachine body 10 by ashaft 132, a multiplicity of, e.g., 8 sets ofgrip members 133 for gripping thevessel 1 are radially attached to therotating disk 131, and the locations corresponding to thegrip members 133 on therotating disk 131 serve as placinglocations 134. - Each of the
grip members 133 is composed of a pair of turningclaws vessel 1. Although Figure 25 shows only one of the turningclaws claws rotating disk 131 byshafts gears shafts above vessel 1. Usually, the turningclaws tension spring 137 attached to one of thegears 136. - Further, since opening and closing of the
grip member 133 is controlled by an arrangement similar to thegrip members - A mechanism for performing a tightening operation is such that a tightening
member 136 is vertically disposed above thevessel 1 on the placinglocation 134 so that the tighteningmember 136 can be lifted and lowered by a vertically movingmeans 135 supported by theabove shaft 132 and a tightening means 138 composed of a pair of right and leftendless belt members member 136 in correspondence with the upper portion of thevessel 1 with the cap supplied from the above mounting unit E so that the tightening means 128 can pressingly hold thecap 4 of thevessel 1. - The above vertically moving
means 135 is arranged such that acylindrical member 140 having acam groove 139 defined around the periphery thereof is attached to theabove shaft 132 and a movingmember 141 provided at the upper portion of theabove tightening member 136 is engaged with thecam groove 139 of thecylindrical member 140, so that theabove tightening member 136 is lifted and lowered as the abovecylindrical member 136 is rotated. - The tightening
member 136 of the above tightening means 138 containshorizontal turning plates shafts drive shafts horizontal turning plates shafts shafts horizontal turning plates cap 4. Each of urethane or rubbertype belt members rings gears above drive shafts above belt members above cap 4. - Further, this tightening means 138 is associated with an actuation means 151 for pressing against and retracting from the outside periphery of the
cap 4 of thevessel 1, and thus when an advancing and retracting means 154 such as a fluid cylinder or the like the base portion of which is attached to theabove tightening member 136 is associated with thelever 153 projected from thesupport cylinder 152 of the abovehorizontal turning plate 143 and operated, the abovehorizontal turning plate 143 is turned about thedrive shaft 142, and as a result pressing against and retracting from the outside periphery of thecap 4 are arbitrarily carried out. The synchronizing gears 155, 155 mounted on theabove drive shafts horizontal turning plates belt members cap 4. - The actuation means 151 for pressing against and retracting from the outside periphery of the
cap 4 of theabove vessel 1 may be arranged to perform a linear motion executed by thehorizontal turning plate 143 as shown, for example, in Figures 28 and 29 in addition to the arrangement for performing the swing motion executed by thehorizontal turning plate 143. In the case shown in Figure 28, this motion is carried out by associating the advancing and retracting means 154 with thehorizontal plate 143, and in the case shown in Figure 29, a movingplate 156 capable of advancing and retracting is provided with thehorizontal plate 143, and press rings 148, 148 and the tension rings 157, 157 of thebelt member 137 are supported on the movingplate 156 and the movingplate 156 is associated with the advancing and retracting means 154 to thereby execute an advancing and retracting motion. - There is provided a
grip member 158 for gripping thenozzle portion 7 of thecap 4 when thecap 4 is tightened by the above tightening means 138. Thegrip member 158 is arranged such that opening/closing levers 161, 161 having receivingrollers shafts member 159 located just above thevessel 1 waiting at theabove placing location 134, that is, just above the insertedcap 4, and rubber typeelastic members pump portion 8 of thecap 4 and preventing thecap 4 and the like from being damaged and slipped are attached to the lower edge of the opening/closing levers 161, 161. The opening/closing levers 161, 161 are opened and closed in such a manner that ataper cone 164 is inserted into the above holdingmember 159 and thetaper cone 164 is advanced and retracted by an actuating means (not shown) to press the above receivingrollers - In Figure 2, 165 designates a third transit means for supplying the
vessel 1 with the tightened cap to the transfer unit G. Since this third transit means 165 has the same arrangement as that of the first and second transit means 29 and 130, it is not described in detail. - The above transfer means G for the
vessel 1 with thecap 4 employs an endless rail type conveyer and also is used as the above transfer unit A for thevessel 1. - As shown in Figure 30, the drive means H in the above description drives the above first transit means 29, disk-shaped transfer means 49, mounting unit E, second transit means 130, tightening unit F, and third transit means 165 together in synchronism in such a manner that the rotation of a
motor 166 mounted on themachine body 10 is transmitted to atransit shaft 168 through a connectingmember 167 such as a belt or the like and then separately transmitted toreduction gears intermediate shaft 168 through connectingmembers - In addition, gears 174, 175 are mounted on the
output shafts gear 174 mounted on theshaft 51 of the first transit means 29 is meshed with thegear 174, agear 36 mounted on theshaft 54 of the mounting unit E is meshed with thegear 176, and further agear 177 mounted on the shaft of the disk-shaped transfer means 49 is meshed with thegear 36 for the transmission of rotation. - In addition, a
gear 179 mounted on theshaft 178 of the third transit means 165 is meshed with thegear 175 mounted on theoutput shaft 173 of theabove reduction gear 171, agear 180 mounted on theshaft 132 of the tightening unit F is meshed with thegear 179, and further agear 182 mounted on theshaft 181 of the second transit means 130 is meshed with thegear 180 for the transmission of rotation. - Next, operation of the above embodiment will be simply described.
- When the respective drive means 11 and H are started to operate the respective units and means, they are operated together in synchronism.
- First, when
vessels 1 formed to have, e.g., an oval cross section and filled with a liquid such as detergent or the like are continuously transferred by the transfer unit A at the starting end side of themachine body 10, thesevessels 1 are supplied to the vessel delivery unit C waiting on the transfer unit A. - At this time, these
vessels 1 are transferred with the printed surfaces thereof uniformly faced to a predetermined direction. - Then, the
vessel 1 reached to the vessel delivery unit C is accommodated in the recessed portion of thetransfer screw 31 at the starting point thereof and supplied to thecutout 52 of the horizontal rotatingmember 50 in the first transit means 29. - The thus supplied
vessel 1 is guided by theguide 52a provided along the outside periphery of the rotatingmember 50 while accommodated in theabove cutout 52 and delivered onto the placinglocation 56 of the mounting unit E as the above rotatingmember 50 is rotated. - Note that when the
vessel 1 supplied to the unit E is formed to a round shape, the projectingrod 73 projecting from thepositioning plate 68 of thehorizontal disk 53 is turned as thepositioning plate 68 is rotated, while thevessel 1 is transferred, and when the projectingrod 73 is positioned at the recessedportion 2 defined on the bottom of thevessel 1, it is engaged therewith by thespring 72 thereof so that thevessel 1 is rotated on the placinglocation 56 until the engagingmember 96 is locked to thecutout 90 in the control means 75, i.e., the printed surface of thevessel 1 is positioned. - On the other hand, a multiplicity of
caps 4 with nozzle put into thecabinet 13 of the first arrangement unit B1 are moved upward by being engaged with the cleaning-outplates 19 as the combing-updisk 16 is rotated and prevented from being dropped at the top portion thereof in such a manner that thecaps 4 are locked to thesteps 22 at the lower edges thereof, and thecaps 4 not properly accommodated by the above cleaning-outplates 19 are dropped by thefeather members 27 of the sweeping-down means 23 provided at the top portion and then combed up again. - Then, thus arranged
caps 4 with nozzle are supplied from the outlet and dropped from thechute 42 of the cap delivery unit D in a horizontally-brought-down state and supplied to the second cap arrangement unit B2. - The thus transferred
caps 4 with nozzle are dropped by the dead weight thereof and further transferred while thehose 6 of each of thecaps 4 is supported by the receivingpiece 42a of the second cap delivery unit B2 and thepump portion 8 thereof is supported by the receivingpiece 42b thereof. While thecaps 4 are transferred, thepump portion 8 engaged with the above downwardlyinclined receiving piece 42b is turned and thus thenozzle portion 7 having a large difference of weight is faced downward, and thus the attitude of thecap 4 with nozzle is gradually lifted by the bending of thechute 42 in the state that thenozzle 7 is uniformly faced to a predetermined direction and thecap 4 is dropped along thechute 42 in a vertical state. Thus, a predetermined amount of thecaps 4 stored by thestopper 44 at the lower portion of thechute 42 wait for a next operation. - The
cap 4 regulated by thestopper 44 releases thestopper 44 in synchronism with the turning motion of thevessel 1 performed by the mounting unit E and supplied to the disk-shaped transfer means 49 by an air ejection force of thesupply member 45. - Then, the
cap 4 with nozzle is transferred to the delivery position of the mounting unit E gripping thevessel 1 along theguide 47 with thesemi-annular groove 46 while turned by being pushed by thesupply cutouts 38 of the transfer means 49, with the periphery of thecap 4 and the lower end of thetrigger portion 8 engaged with thecutout 48. - When the vertically moving
rod 113 of the cap supply means 106 waiting above the grippedvessel 1 is lowered by the actuation of thecam groove 110 of the vertically movingmeans 108 and the movingmember 114 engaged therewith and theclaw members 116 of the suspension means 109 provided at the lower end of the above vertically movingrod 113 are opened, thecap 4 with nozzle having reached the delivery position and waiting above the transfer means 49 is kept vertically with thepump portion 5 thereof gripped by theclaw members 116. - Further, the
above cap 4 with nozzle is inserted into thevessel 1 supplied onto the placinglocation 56 of the mounting unit E, and at this time even if thehose 6 of thecap 4 is greatly curved, thehose 6 is kept vertically by being squeezed in such a manner that the upper portion of thehose 6 is gripped by actuating thegrip claws grip claws member 122. When the above vertically movingmeans 108 is actuated in this state to insert thehose 6 into the opening at the mouth of thevessel 1 and then theabove grip claws cap 4 is set to thevessel 1. - Then, the
vessel 1 andcap 4 with nozzle are continuously turned in synchronism to each other by the mounting unit E and supplied to the next tightening unit F through the second transit means 130. - Further, these
caps 4 are tightened by the tightening means 138 of the tightening unit F with a predetermined tightening torque and sequentially discharged by the transfer means G or A provided at the terminal end of theabove machine body 10. When thevessel 1 into which thecap 4 is inserted reaches the lower portion of the above tightening means 138, thebelt members rings horizontal turning plate 143 is turned inwardly by the actuation means 151 and abutted against the periphery of thecap 4 to obtain a predetermined torque, and then thebelt members drive shafts belt members cap 4 with a relatively large contact surface created therebetween to thereby tighten thecap 4. - Note that modifications of the above actuation means shown in Figures 28 and 29 may be employed by the apparatus of the present embodiment, operation thereof is not described here.
