Description

  The present invention relates to a tape bundling device for a bag packaging body, and in particular, a bundling method for closing a bag neck formed by drawing a part of a bag packaging body in which a package is biased in a bag and closing it with a bundling tape. And an apparatus for the same.

  Conventionally, a bag package body in which a plurality of bar-shaped items such as bar-shaped foods and vegetables are packaged is formed by drawing a bag neck and binding the bag neck with a tape to freely move the package in the bag. Limited to some extent, it may be distributed as a relatively tight package that is easy to handle in a single package and sold.

  As an example of such a method and apparatus for binding a bag mouth of a bag package with a single-sided adhesive tape, the present applicant has applied for a patent and obtained a patent (Patent Document 1). This tape bundling method is carried in a gripped state in which the bag packages are alternately gripped alternately by the gripping means of the gripping means which are arranged on each side in the transport direction of the bag package and make a pair. The bag neck of the bag package conveyed by the gripping means is squeezed by a squeezing means operating on the side opposite to the side gripped by the gripping means, and the bag package is received in place of the gripping means, and the bag neck The bag packaging body in a state where the bag is squeezed is fed into the tape binding device by the squeezing means, whereby the bag neck portion of the bag packaging body is tape-bound.

  The tape bundling device is arranged on each side of the bag packaging body in the conveying direction to form a pair and alternately grip each other bag packaging body in a gripping state. A pair of gripping means for transporting, a throttle that operates on the side opposite to the side gripped by the gripping means and squeezes the bag neck of the bag package transported by the gripping means and receives the bag package in place of the gripping means And a tape binding device for binding a tape to the bag neck of the bag package which is fed by the squeezing means in a squeezed state.

  According to the tape bundling method and apparatus configured in this way, a pair of gripping means is disposed on each side in the transport direction for transporting the bag package, and one pair of gripping means on each side is placed. The bag packaging bodies are alternately gripped, and each gripping means conveys each bag packaging body in a gripping state. The squeezing means that operates on the side opposite to the side gripped by the gripping means squeezes the bag neck of the bag wrapping material conveyed by the gripping means. The squeezing means feeds the bag package received in place of the gripping means to the tape binding device in the squeezed state of the bag neck, and the tape binding device winds the tape around the bag neck of the bag packaging to bind them.

  The bag package is transported in a posture along the transport direction with the lateral seal portion that seals the bag opening, and by associating the direction of the bag package with the transport direction, gripping by the gripping means is performed from the side of the bag package. At the same time, the bag neck is squeezed from the front and back in the conveying direction. The gripping means is an adsorbing means composed of an upper adsorbing portion that adsorbs the flat upper portion of the bag neck and a lower adsorbing portion that adsorbs the bag main body portion containing the package of the bag package, and the conveying direction It acts on a wide side part facing the side of the bag and can stably hold the bag package. Further, the squeezing means can perform an operation of squeezing the bag neck portion without interfering with the suction means between the upper suction portion and the lower suction portion of the suction means. The squeezing means includes a pair of squeezing arms that open and close in the front and rear direction of the bag package, and the neck of the bag can be squeezed by opening and closing in the front and rear direction of the transport.

  Further, the present applicant is guided and guided the body to be bound and the binding tape with respect to the binding method and apparatus for closing the bag neck formed by drawing a part of the bag package with the binding tape. By abutting on a specific part such as a wall surface of the member to be averaged without repeatedly abutting with a strong force, the action of the force on the bound body is reduced, and the guiding and guiding member is worn. Has been proposed and patented (Patent Document 2).

  According to the tape bundling method and apparatus disclosed in Patent Document 2, the bundling tape is wound around the outer peripheral surface by a ring piece that is loosely fitted around the engagement shaft and can be swung around the engagement shaft. It is guided in the state of being pushed out. The front end side portion of the binding tape guided by the ring piece is delivered and locked from the outer peripheral surface of the ring piece to a tape locking mechanism that can come in contact with and separate from the ring piece in the radial direction. Moves the object to be bound to the guide path formed in the frame in the vicinity of the outer peripheral surface of the ring piece with respect to the binding tape that has been transferred from the ring piece to the tape locking mechanism and locked. Then, the front end side portion of the bundling tape pulled back from the tape locking mechanism and the rear end side portion of the bundling tape fed out from the ring piece are wound around the binding object. The bundling tape wound around the bundling body is completed by bundling both ends left from the periphery of the bundling body.

  By the way, in the tape bundling method and apparatus disclosed in Patent Document 1, there are several points to be overcome when higher speed processing is required. One of these points is that the bag conveyor body in the tape bundling device is driven by a surface cam / swing lever system and the conveyance unit is moved back and forth by the surface cam. When the driving speed of the cam follower is increased to a predetermined speed or more, the cam follower cannot follow the movement of the face cam, and the cam follower jumps from the face cam. In addition, the front and rear aperture claws may cause mechanical interference and breakage, and therefore cannot be rotated at high speed. In addition, when the pressure of the spring air cylinder used to engage the cam follower with the face cam is increased so that the cam follower does not fly, the contact of the face cam with the cam follower increases. Premature wear and the life of the spring air cylinder may be shortened, possibly causing damage. As a result, in the surface cam system, the maintenance cycle of the apparatus is shortened, and further improvement is demanded in this respect.

  If the face cam is changed to the groove cam, the followability can be improved. However, since the cam and the cam follower are always engaged and cannot be easily detached, the operation mode of the conveying section that reciprocates alternately is changed. Is difficult. If it becomes so, it will become difficult to make the state which separated the tape binding apparatus from the bag making filling packaging apparatus, and selection of the manufacturing mode which manufactures a pillow package as it is, without processing a tape binding is difficult.

  The second point to be overcome when performing higher speed processing is that the synchronization pattern with the transport unit cannot be adjusted because the tape unit is also advanced and retracted by a cam.

  The third point to be overcome when performing high-speed processing is the dropping of the bundled pillow package on the discharge chute. The bundled pillow package is dropped into the discharge chute by its own weight when the squeezing claw that squeezes the bag neck is opened, but the dropping posture becomes unstable at high speed. If the dropping posture is not stable, it may stop on the discharge chute and collide with the next falling pillow package to block the discharge chute.

Japanese Patent No. 4472113 Japanese Patent No. 4537532

  Therefore, it is possible to easily select the production mode of the bag-wrapped bag package and the production mode of the non-tape bag package, and at the same time, high-speed operation is possible, and the binding tape is wound. There is a need for a tape binding device for a bag package that can easily adjust the timing and accurately discharge the bundled bag package.

  An object of the present invention is to solve the above-described problem, and a manufacturing mode for manufacturing a bag-wrapped bag package by binding the tape to the bag neck of the manufactured bag-packed body by a tape binding device. And a tape bundling device without the need for tape bundling, making it possible to easily select a production mode for producing a bag package that is not tape bundled, and capable of high-speed operation, and It is an object of the present invention to provide a tape binding device for a bag packaging body which can easily adjust the winding timing and can accurately discharge the bound bag packaging body.

  In order to solve the above-mentioned problems, a tape bundling device for a bag package according to the present invention includes the bag packaging in a transport unit having two transport parts arranged in parallel along the direction in which the lateral seal portion of the bag package extends. A pair of transport means for transporting the body, each of which is disposed in each transport portion of the transport section, and alternately grips the bag packaging body alternately and transports the bag packaging body in a gripping state. A gripping means, a squeezing means that operates on a side opposite to a side gripped by the gripping means and squeezes a bag neck of the bag package conveyed by the gripping means, and receives the bag package instead of the gripping means; and In a bag packaging body tape binding device comprising a tape binding device for binding a tape to the bag neck portion of the bag packaging body fed by the squeezing means while the bag neck portion is in a squeezed state, the transport means includes a drive source A camshaft that is rotated by the output of the drive source, two groove cams that are driven to rotate by the camshaft, and a cam follower that is cam-engaged with the groove cams. The camshaft is provided with an electromagnetic clutch between the groove cams, and an electromagnetic brake is applied to the camshaft portion to which the output of the driving source is not transmitted when the camshaft is disconnected by the electromagnetic clutch. It is characterized by providing.

  According to this bag packaging body tape binding device, during normal operation, the transport means alternately transports the continuously supplied bag packaging body in two transport portions in mutually opposite phases. In order to cancel the alternate conveyance in the reverse phase by the conveyance means, for example, to stop in the same phase state, first turn off the electromagnetic clutch, separate both camshaft parts, and the one that is not rotationally driven directly by the drive source The camshaft portion (and the groove cam attached to the camshaft portion) is stopped and locked by operating the electromagnetic brake at the stop position. After that, the camshaft portion (and the groove cam attached to the camshaft portion) that is directly driven to rotate by the drive source is rotated to be in phase with the already stopped and locked camshaft portion (and groove cam). Stop the drive source in this state.

  With respect to the tape binding device for the bag packaging body, the gripping means grips the bag packaging body manufactured and discharged by the vertical bag making and packaging machine with respect to the vertical bag making and packaging machine and It is applicable so that a conveyance part conveys. When the tape binding device is used in combination with a bag making filling and packaging machine, a production mode for stopping the production of the pillow packaging body by the bag making filling packaging machine, and tape binding at the neck of the bag for the produced pillow packaging body. It is preferable that the production mode can be selected in which even the pillow package is produced. When the tape binding device is not used, it is necessary to avoid interference with the bag making filling and packaging machine. Therefore, when the tape binding device and the vertical bag making filling packaging machine are operated together and used in the mode of manufacturing a pillow-wrapped pillow body, both camshaft portions are integrated with the electromagnetic clutch turned on. And the gripping means and the diaphragm means are driven in opposite phases outside both the conveying portions. When manufacturing a pillow package without binding using the tape binding device in a mode in which only the vertical bag making and filling and packaging machine is in operation, stop one of the transport parts in the retracted position and disconnect the electromagnetic clutch. At the same time, the electromagnetic brake is activated. As a result, the groove cam for one conveying portion is disconnected from the drive and becomes free, but the position can be maintained because the electromagnetic brake is operating. Next, the camshaft is driven by the output of the drive source to stop the other conveyance portion in the retracted position. Thereby, both conveyance parts of a tape binding apparatus can be fixed in the retreat position where both interference with a bag making filling packaging machine is avoided.

  The tape binding device for the bag wrapping body is reciprocated in synchronism with the feed of the squeezing means along the feeding direction of the bag wrapping body, and the reciprocation of the tape binding device can be driven by a servo motor. By performing the reciprocating motion of the tape bundling device with a servo motor, it becomes possible to set the timing and stroke of synchronization with the squeezing means of the tape bundling device to optimum values. Furthermore, when replacing the binding tape reel, the tape binding device can be moved to the replacement position independently.

  In this bag wrapping tape binding apparatus, a holding member for the bag wrapping body driven by an air cylinder is provided at a discharge position of the bag wrapping body that has been tape-bound, and the holding member is provided before the squeezing means is opened. After the bag package is held and the squeezing means is opened, the bag package can be opened. The bag package can be stably dropped by holding the bag package with the holding member before opening the squeezing means and opening the holding member after the squeezing means is opened. By providing the holding member that performs the operation of holding the bag package when the bag package is discharged, the followability in the high-speed operation region can be stabilized in the tape binding device.

  Since the tape bundling device for a bag package according to the present invention is configured as described above, during normal operation, the conveying means alternates the bag package that is continuously supplied in two conveying portions with phases opposite to each other. Transport to. On the other hand, by combining the operation of the electromagnetic clutch and the operation of the electromagnetic brake, it is possible to eliminate the alternate conveyance in the opposite phase by the conveyance means and to stop the two conveyance portions in the same phase. Therefore, the tape binding is performed on the bag neck by the tape binding device on the bag neck body manufactured, and the manufacturing mode for manufacturing the tape package bag binding body, without tape binding by the tape binding device, It can be easily combined with the production mode for producing the bag package that is not tape-bound, and can be operated at high speed, and the winding timing of the binding tape can be easily adjusted and bound. It is possible to provide a tape bundling device capable of accurately discharging a bag package.

  Hereinafter, an embodiment of a tape binding device for a bag package according to the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an outline of an example in which the tape binding device 100 for bag packaging according to the present invention is applied to a vertical bag making filling packaging machine 200. The apparatus on the right side of FIG. 1 schematically shows a vertical bag making and filling and packaging machine 200. The vertical bag making and filling and packaging machine 200 uses, for example, a web-like packaging material fed from a roll as a former 201. After being bent into a curved shape by passing it through, it is formed into a cylindrical packaging material by heat-sealing both side edges of the web-shaped packaging material with a vertical sealer 202, and further filling the product into the cylindrical packaging material And the horizontal sealer 203 heat-seal the cylindrical packaging material in the transverse direction, and repeatedly perform sealing of the upper end portion of the preceding pillow package P and sealing of the bottom end portion of the subsequent pillow packaging bag. is there. The manufactured pillow package P is separated from the cylindrical packaging material by a cutting means such as a cutter incorporated in the horizontal sealer 203 and discharged outside the machine through the discharge chute 204.

  A tape binding device 100 is attached to the side of the vertical bag making and filling machine 200, and the pillow package P manufactured by the vertical bag making and filling machine 200 is not discharged to the discharge chute 204. When the paper is horizontally transported from the transport start position S1 to the tape binding device 100 in the vertical bag making filling and packaging machine 200, the neck portion of the pillow packaging body Pa (rather than the product filled inside) in the tape binding device 100. The upper part of the bag until the upper end seal is squeezed and the tape is wrapped around the squeezed part to bind it, and a bundled pillow package is manufactured at the lateral conveyance end position S3 in the tape binding device 100. The pillow package Pb bound from that position is discharged through the discharge chute 190.

  According to the vertical bag making and filling machine with the tape bundling device shown in FIG. 1, the pillow package Pa manufactured by the vertical bag making and filling machine 200 is directly passed through the discharge chute 204 of the vertical bag making and filling machine 200. If discharged, the unwrapped pillow package Pa is obtained. Moreover, if the pillow packaging body Pa manufactured by the vertical bag making and packaging machine 200 is laterally transported and transported to the tape binding device 100, the bound pillow packaging body Pb is manufactured. In a vertical bag making and packing machine with a bundling device, when the bundling device is not operated, only the pillow package can be manufactured, and when the bundling device is operated together, the pillow package is tape-bound. It is possible to manufacture pillow packages that are transported and bound to the apparatus. As described above, the vertical bag-filling and packaging machine provided with the bundling device can be used for both the production of the pillow package and the bundled pillow package, and any one of the production modes can be selected by selection. .

The basic configuration of the bag wrapping tape binding apparatus according to the present invention is the same as that of the bag wrapping tape binding apparatus disclosed in Patent Document 1 (Patent No. 4472113). The configuration will be described.
The tape bundling device for a bag package shown in Patent Document 1 (Patent No. 4472113) sucks and holds the pillow package at the conveyance start position directly below the horizontal sealer of the vertical bag making filling and packaging machine, and conveys it in the horizontal direction. It is a device that transports to a completion position, covers the upper part of the bag package in the meantime, winds a binding tape, manufactures a bundled pillow package, and discharges it downward at the transfer completion position.
The bundling device includes a lateral transport unit that transports the packaging body from the transport start position to the transport completion position, and a binding tape winding unit that winds the binding tape. It has claw crests on the top.
Of these four elements, the horizontal transport unit, suction member, claw claw, and binding tape winding unit, the suction member is operated by operating the suction valve at electrical timing. The binding tape winding portion is operated by a mechanism using a cam.
The horizontal transfer unit is a pair of A, B, and two transfer units, each of which operates alternately with a phase difference of 180 degrees to achieve high-speed processing. Each of the two transfer units includes a claw claw and a suction member.
Hereinafter, with reference to FIGS. 15-19, the structure employ | adopted also in the tape binding apparatus of the bag packaging body which is this invention is demonstrated.

  FIG. 15 is a perspective view showing a main part of one embodiment of a tape wrapping device for a bag package described in Patent Document 1, and FIG. 16 shows an operation of the tape binding device for a bag wrap shown in FIG. It is a schematic explanatory drawing which shows. FIG. 17 is a plan view showing a part of the bag wrapping tape binding apparatus according to the present invention shown in FIGS. 15 and 16, and FIG. 18 is a part of the bag wrapping tape binding apparatus shown in FIG. FIG. 19 is a side cross-sectional view of the bag packaging body shown in FIG. 17 with a part removed.

  15 and 16 shows a bag packaging body tape binding device 1 according to the present invention, which is provided in a form attached to the rear stage of a vertical bag making filling packaging machine. The vertical bag-filling and packaging machine is known per se, and forms a web-shaped packaging film into a vertical cylindrical film T (see FIGS. 18 and 19) that runs downward from above. The side seal mechanism 50 seals the bag mouth portion P1 of the previously formed cylindrical bag P and forms the bottom portion P2 of the next bag, and the package is formed in the cylindrical bag in which the bottom portion P2 is formed. Is a packaging machine that continuously manufactures the bag package P by repeating the process of sealing the bag mouth portion P1.

  The bag neck P3 is flattened by appropriate squeezing means acting from the left and right sides with respect to the bag package P in which the bag mouth P1 of the bag package P containing the package therein is sealed by the lateral seal mechanism 50. Is done. The lateral sealing mechanism 50 may be a known mechanism, and is a lower side for thermally sealing and sealing the bag mouth portion P1 of the bag packaging body P formed in advance on each side of the bag packaging body P. A pair of horizontal heat sealers 51 having a side heat sealer 52 and an upper heat sealer 53 for heat-sealing and sealing the bag bottom P2 of the bag package P to be formed next is disposed. One horizontal heat sealer 51b is provided with a cutter 54 that is cut between the upper heat sealer portion 53 and the lower heat sealer portion 52 so as to be separated from the bag formed next and formed next. In the other side heat sealer 51a (see FIG. 19, omitted in FIGS. 15 and 16), a relief 55 for the cutter 54 is formed. Immediately above the pair of horizontal heat sealers 51, a detection plate 63 is provided for detecting whether or not a package is present on the bag neck P3 (see FIG. 15). Since the detection plate 63 operates substantially in synchronization with the lateral heat sealer 51, when a package is present on the bag neck P3 to be bound, the sensor 64 detects a movement different from the normal state of the detection plate 63, and an abnormality is detected. The status is notified.

  In the lateral seal mechanism 50 disclosed in Patent Document 1 (Japanese Patent No. 4472113), as shown in FIG. 17, the rotation output of the motor 56 attached to the frame 45 is transmitted through the first link 57 to the frame. 45 is transmitted to a reciprocating rotation member 58 provided rotatably at 45. The reciprocating rotation member 58 is directly connected to a sealer block 60a for one side heat sealer 51a through a second link 59a. The horizontal heat sealer 51a advances and retreats with respect to the bag package P by the sealer block 60a being guided by the guide rod 62 supported by the frame 45 so as to be freely guided. The reciprocating rotation member 58 is also connected to a sealer block 60b for the other horizontal heat sealer 51b via a second link 59b, a horizontal stay 61, and a guide rod 62, and the horizontal heat sealer 51b is connected to one horizontal heat sealer. Synchronously with 51a, it advances and retreats with respect to the bag package P. The pair of horizontal heat sealers 51a and 51b repeats the operation of moving toward and away from the tubular tube T in synchronization with the filling of the package into the bag. The bag package P which has been applied and the cutter 54 is completed is cut off from the tubular tube T.

  The lateral sealing mechanism 50 is provided with suction means 10 as a gripping means for sucking and gripping the bag package P separated by the cutter 54 on each side of the bag package P (FIGS. 15 and 18). , See FIG. That is, rails 18, 18 extending in a direction parallel to the lateral seal direction of the bag package P are formed on the sealer blocks 60 a, 60 b of the lateral seal mechanism 50, and a pair of suction tools constituting the suction means 10. 11a and 11b are slidably provided on the rail 18 on each side of the bag package P. In FIG. 15, with respect to the suction means 10, only one suction tool 11a on the near side is shown. The bag package P is conveyed in a direction (indicated by an arrow A) in which the rail 18 extends, which is the transverse seal direction of the bag package P, in a state where the bag package P is adsorbed by the adsorption means 10.

  Each adsorber 11 includes a bag containing an upper adsorbing portion 12 that adsorbs the flattened upper portion P4 of the bag neck P3 and a bag package P that is spaced downward from the upper portion P4 of the bag neck P3. It comprises a lower suction portion 13 that sucks the main body portion P5. In each suction tool 11, the upper suction portion 12 and the lower suction portion 13 are configured as a continuous suction box 14, and a suction air hose 15 is connected to the inside of the suction box 14. Corresponding to the upper suction portion 12 and the lower suction portion 13, a plurality of suction holes 16 (partially indicated by reference numerals in FIGS. 15 and 19) are formed on the suction surface of the suction box 14. An appropriate control valve (not shown) is provided on the suction side of the suction air hose 15, and the grip of the bag package P by the suction tool 11 is controlled by controlling the control valve. Since the upper suction part 12 and the lower suction part 13 act from the side of the bag package P and adsorb to the wide surface facing the side of the transport direction A of the bag package P, the bag package P is Grasp stably. Each suction box 14 is spaced apart laterally from the flattened bag neck P3 between the upper suction portion 12 and the lower suction portion 13, and a void 17 is formed between the suction neck 14 and the bag neck P3. The empty space 17 provides a space when the throttle means 20 (to be described later) for bundling enters the bag neck P3 without interfering with the suction tool 11.

  Each suction means 10 that is a gripping means is only shown on one suction tool 11a in FIG. 15, but is disposed on each side in the transport direction (A) for transporting the bag package P. The adsorbing tools 11a and 11b alternately hold every other bag packaging P manufactured continuously, and each adsorbing tool 11 is conveyed along the rail 18 while holding each bag packaging P. To do. That is, as shown in FIG. 16, when one bag 11 is to be sucked at the transport start position S1, which is a discharge position at which one suction tool 11a is discharged from the bag making and filling machine, the other suction tool 11b is sucked. The finished bag package P has been transported to the transport end position S2.

  When both side heat seal parts 51a and 51b approach each other to perform horizontal sealing / cutting, only one of the suction tools (for example, 11a) operates by applying a negative pressure in the suction box 14 based on an appropriate valve operation. The bag package P is adsorbed on one side by the adsorber. When the lateral heat seal portions 51a and 51b are separated from each other, the bag package P is retracted while being sucked and held by one of the suction tools, and the suction tool 11a is packaged during the next packaging operation in the bag making and filling machine. The body P is moved along the rail 18 while being sucked and held, and is sent to a standby position (refer to the position 11a in FIG. 17) corresponding to a conveyance end position (aperture position) S2 where a diaphragm operation described later is performed. In accordance with the lateral sealing operation for the next bag package P in the bag making and filling machine, the adsorbed bag package P is moved from the standby position to the conveyance end position (squeezing position) S2. At this time, the next bag package P manufactured by the bag making and filling machine is sucked and held by the other suction tool 11b, and the same conveyance as described above is performed on the opposite side of the bag package P. The suction tool 11a that has transported the previous bag package P returns to the original transport start position S1 with the suction operation turned off, and prepares for the next suction operation for the bag package P. Thus, the bag packaging body P manufactured one after another is immediately sucked and held by any one of the suction tools 11a or 11b when transported without passing through the waiting time.

  The bag packaging body P transported to the transport end position (squeezing position) S2 in the state of being sucked by the suction means 10 while the next bag packaging body P is being subjected to the lateral sealing operation will be described later. The bag neck P3 is squeezed and delivered by the squeezing operation. The squeezing and bundling operations for the bag package P conveyed to the conveyance end position (squeezing position) S2 are also performed by a pair of squeezing means 20 (20a, 20b) provided on each side of the bag package P. . For each bag package P, the squeezing means 20 operates on the side opposite to the side on which the suction means 10 sucks, and squeezes the bag neck P3 of the bag package P conveyed by the suction means 10. The squeezing means 20 feeds the bag package P received in place of the suction means 10 to the tape binding device 30 with the bag neck P3 being squeezed, and the tape binding device 30 passes the bag neck P3 of the bag packaging P. A slit 31, a binding single-sided adhesive tape 40 supplied from the tape reel 32, a substrate 33 provided with a binding mechanism therein, and a bag package P formed on the substrate 33 and connected to and bound to the slit 31. A hole 34 to be dropped is provided. While the bag neck P3 of the bag package P is passed through the slit 31, the single-sided adhesive tape 40 cut to a predetermined length is wound around the bag neck P3 to perform binding.

  Each of the squeezing means 20a and 20b includes a pair of squeezing arms 21 and 21 that open and close before and after the bag packaging body P in the transport direction A in order to squeeze the bag neck P3 of the bag packaging body P. The squeezing arms 21 and 21 are arranged on the side of the bag package P that is sent in the transport direction A, and opens and closes before and after the transport direction A to squeeze the bag neck P3. Each throttle arm 21 is composed of two upper and lower arm portions 22 and 22, and the vertical distance between the upper and lower arm portions 22 and 22 is the thickness of the tape binder 30 so that the tape binder 30 described later can pass through. Is set to a width that can be accommodated.

  The diaphragm means 20 will be described with reference to FIGS. 15, 16, 17 and 18. Each throttle arm 21 is provided with a gear 23 on a rotation shaft portion which is a base, and a gear 23 provided on one throttle arm 21 and a gear 23 provided on the other throttle arm 21 are engaged with each other. A groove 24 that engages with the bag neck P3 is formed at the tip of each throttle arm 21. Since the gears 23 and 23 have the same number of teeth, the pair of aperture arms 21 and 21 are synchronously rotated by the same rotation amount in opposite directions by the meshing of the gears. Each squeezing means 20 is provided on a moving plate 28 that reciprocates on an extension line in the conveyance direction A of the bag package P. In order to open and close the aperture arms 21 and 21, cam means 25 for converting the reciprocating motion of the moving plate 28 into a rotational motion is provided. The cam means 25 comprises a gear 26 that meshes with one gear 23 and a cam follower 27 provided at a position eccentric to the gear 26. The cam follower 27 engages with a cam plate attached to a frame (not shown). Yes. When the moving plate 28 reciprocates, the cam follower 27 receives the cam action with the cam plate and rotates the gear 26, so that the pair of throttle arms 21 and 21 are synchronized with each other via the gear 23 that meshes with the gear 26. It is driven to open and close, and the bag neck P3 of the bag package P is squeezed from the front and rear direction in the conveying direction A between the opposed grooves 24.

  As shown in FIG. 18, the moving plate 28 is driven by a mechanism such as a link cam mechanism that converts the rotation of the motor 65 into a reciprocating motion, so that the suction means 10 transports the bag package P (a diaphragm end). Position) Reciprocates in synchronization with the operation of the suction means 10 between S2 and a bundling end position S3 described later. That is, the rotation of the motor 65 is transmitted to the sprocket 67 through the chain 66, and the coaxial cam 68 provided on the sprocket 67 is driven to rotate. As the cam 68 rotates, the swing lever 69 as a cam follower rotates around the support shaft 70, and the movable plate 28 is moved via an intermediate lever connected to the tip of the swing lever 69 with a certain degree of freedom. It is reciprocated.

  The tape binder 30 may preferably have a structure disclosed in Patent Document 2, but is not limited thereto. The tape binder 30 is formed with a slit 31 through which the bag wrapping body P with the squeezed bag neck P3 is passed, and the slit 31 is located along an extension line in the conveyance direction A of the bag wrapping body P. Yes. By forcibly passing the narrowed bag neck P3 through the slit 31, the single-sided adhesive tape 40 for binding supplied from the tape reel 32 to the slit 31 can be wound around the bag neck P3.

  The tape binder 30 is fed along the feed direction of the bag package P in synchronization with the feed of the squeezing means 20 and at a speed slower than the feed speed of the squeezing means 20. In order to reciprocate the tape binder 30 in synchronism with the feed of the throttle means 20, the swing lever 75 (see FIG. 18) is swung by another cam (not shown) provided coaxially with the sprocket 67. Similar to the lever 69, it swings around the support shaft 76 and is connected to the tip end portion 77 of the swing lever 75 via the intermediate connecting portion 78 to the tape binder 30. By reciprocating the tape binder 30, the relative movement speed between the bag package P and the tape binder 30 in the tape binding process in which the narrowed bag neck P3 passes through the slit 31 is lowered. Therefore, in the period from the start to the completion of one tape bundling operation, a long time is secured for the bundling operation, and the bundling operation is performed relatively slowly. Impact and damage to the bag package P are prevented. Since the moving direction of the suction means 10 which is a gripping means for transporting the bag package P and the moving direction of the squeezing means 20 and the tape binder 30 are aligned, the layout of the suction means 10 and the squeezing means 20 will be described. Is simplified, the drive mechanism is simplified and operational interference is avoided.

  In addition, the reciprocating movement of each squeezing means 20 by the moving plate 28 is synchronized with the gripping and conveying of the bag package P by the suction means 10, and the conveyance end position (squeezing position) S <b> 2 for squeezing the bag neck P <b> 3 and the tape binder 30. Is performed with the binding end position S3. That is, in synchronization with the operation of the suction means 10 that grips and conveys the bag package P, the movable plate 28 provided with the respective throttle means 20 reciprocates between the throttle position S2 and the binding end position S3. For example, the bag packaging body P transported by the suction tool 11a is, in the transport end position (squeezing position) S2, the squeezing means 20b (at this time, disposed on the side surface opposite to the suction tool 11a with respect to the bag packaging body P). The bag neck P3 is squeezed by the movement plate 28 being sent back to the squeezing position S2. The squeezing means 20b receives the bag package P in place of the adsorbing tool 11a, and the bag wrapping body P ends the binding in the tape binder 30 with the bag neck P3 being squeezed by the squeezing means 20b by the feed of the moving plate 28. Sent to position S3. During the feeding, the single-sided adhesive tape 40 is wound around the narrowed bag neck P3 by the tape binder 30 and bound.

  For one bag package P, the side on which the squeezing means 20 for squeezing the movable plate 28 and the bag neck P3 is opposite to the side on which the suction means 10 for conveying the bag package is provided. Located on the side. Therefore, the suction means 10 and the squeezing means 20 do not interfere with each other at the conveyance end position (squeezed position) S2 where the bag package P is conveyed. In particular, since the void 17 is formed in the suction tool 11 corresponding to the range in which the pair of throttle arms 21 and 21 open and close, the suction tool 11 and the suction tool 11 when the throttle arms 21 and 21 narrow the bag neck P3. There is no collision.

  When the squeezing arms 21 and 21 of one squeezing means 20 squeeze the bag neck P3 of the bag wrapping body P, the bag wrapping body P already sent to the tape binding device 30 by the other squeezing means 20 is the single-sided adhesive tape 40. Therefore, the bundled bag package P is discharged from the tape binder 30 and carried out by an appropriate means when the throttle arms 21 and 21 are opened. When the bag neck P3 is squeezed by one of the squeezing means 20 and the bag package P is in the feeding stroke for feeding it into the tape binder 30, the squeezing arms 21 and 21 of the other squeezing means 20 are in the expanded state and the return stroke. Therefore, the distal ends of the diaphragm arms 21 and 21 are retracted from the slit 31 with respect to the distal end of the other diaphragm means 20. Therefore, one of the diaphragm means 20 in the feeding stroke and the other diaphragm means 20 in the return stroke can pass each other in a non-interfering state. The pair of squeezing means 20 and 20 alternately perform the squeezing operation on the bag wrapping body P, and the bag wrapping body P from the squeezing arms 21 and 21 is fed to the tape binding device 30 with the bag neck P3 being squeezed. Since the return to the conveyance end position (squeezing position) S2 is performed after the release, the bag neck P3 and the tape bundling that are successively conveyed by the gripping means while maintaining the conveyance speed. Can be processed at high speed.

  Next, portions to which the present invention is applied will be described. 2 to 4 show driving force transmission from a drive servo motor in a bag binding unit for tape packaging according to the present invention to a pair of conveying / throttle units arranged on the left and right with respect to the conveying direction of the pillow package. FIG. 2 is a schematic diagram showing a main part of a driving force transmission system from a driving servomotor to each conveying swing lever for a pair of conveying / diaphragm units and to a diaphragm claw opening / closing lever. FIG. 3 is a perspective view of the driving force transmission system shown in FIG. 2, and FIG. 4 is a perspective view showing a conveyance / throttle unit that is alternately driven by the driving force transmission system shown in FIGS. .

  As shown in FIG. 2, the driving force transmission system 101 to the conveying / throttle unit includes a camshaft via an appropriate power transmission means (chain transmission means) 102a in which the output rotation of the drive servo motor 102 of the tape bundling apparatus 100 is appropriately transmitted. The camshaft 103 is rotated by being transmitted to 103. The cam shaft 103 is rotatably supported by a bearing (not shown) with respect to the frame of the tape binding device 100. The camshaft 103 is divided into left and right shaft portions 103a and 103b, and both shaft portions 103a and 103b are connected to each other by an electromagnetic clutch 104 disposed in the center portion so as to be separable from each other. Cam plates 105a and 105b having groove cams are attached to the left and right shaft portions 103a and 103b, respectively, on the outer sides of conveying rocking levers 107a and 107b described later. Rotate by rotation.

  As shown in FIGS. 2 and 3, cam followers 108a, 106b attached to intermediate portions of the swing levers 107a, 107b for conveyance are provided in the cam grooves 106a, 106b (only 106b is shown in FIG. 3) of the cam plates 105a, 105b. 108b is fitted. Further, in the transport swing levers 107 a and 107 b, bosses 109 a and 109 b provided at the base ends of the transport swing levers 107 a and 107 b are rotatably fitted to the lever swing fulcrum shaft 111 supported by the frame 110. ing. Therefore, as the cam plates 105a and 105b rotate, the conveying rocking levers 107a and 107b rock around the lever rocking fulcrum shaft 111 by the cam action of the cam grooves 106a and 106b and the cam followers 108a and 108b. The transport / throttle units 130a and 130b engaged with the front ends of the transport swing levers 107a and 107b reciprocate linearly in the transport direction of the pillow package. The swinging operation of the transport swing levers 107a and 107b by the cam plates 105a and 105b will be further described later with reference to FIG.

  In relation to the camshaft 103, an electromagnetic brake 112 is provided at the shaft end portion 103c of the shaft portion 103a opposite to the shaft portion 103b driven by the drive servomotor 102. The electromagnetic brake 112 is turned on to apply the brake in response to the connection between the shaft portions 103a and 103b being separated by the off operation of the electromagnetic clutch 104, thereby preventing the shaft portion 103 from rotating blindly. ing.

  In order to stop the conveying unit (and hence the conveying rocking levers 107a and 107b), for example, in the same phase, first, the electromagnetic clutch 104 is turned off to separate the camshaft portions 103a and 103b. The camshaft portion 103a (and the groove cam attached to the camshaft portion) that is not directly rotationally driven is stopped and locked by operating the electromagnetic brake 112 at the stop position. Thereafter, the camshaft portion 103b (and the groove cam attached to the camshaft portion) which is directly rotated by the servo motor 102 is rotated, and the camshaft portion 103a (and groove cam) which has already been stopped and locked is rotated. Stop the drive source in the same phase as.

  The shaft portion 103 is provided with a diaphragm claw drum cam 113 in which a cam groove 114 is formed. The diaphragm claw opening / closing lever 115 (FIGS. 3 and 7) is connected to the cam groove 114 of the diaphragm claw drum cam 113. A cam follower 116 that engages the cam is provided. Accordingly, in accordance with the rotation of the camshaft portion 103a, the cam follower 116 moves in a direction parallel to the axial direction of the camshaft 103 by the cam action with the cam groove 114, and the slide blocks 153a and 153b operate to move the aperture claw. Open and close (FIG. 4). Further, the tape bundling device 100 is provided with a tape unit advance / retreat servomotor 117, the output rotation is transmitted to the belt 118, and the belt 118 cooperates with the belt clamp member 119, and the tape unit 140. Are advanced and retracted (FIG. 6).

  As shown in FIG. 4, the upper end portions of the conveying rocking levers 107 a and 107 b protrude upward from the long holes 121 a and 121 b formed in the upper table 120 of the tape bundling device 100. The upper ends of the levers 107a and 107b are linked to the transport / throttle units 130a and 130b via the arms 122a and 122b. Therefore, when the conveying rocking levers 107a and 107b are swung by the cam action of the cam grooves 106a and 106b of the cam plates 105a and 105b and the cam followers 108a and 108b, the conveying / throttle unit 130a is interposed via the arms 122a and 122b. , 130b is reciprocated while being guided along the guide rails 131a, 131b.

  Regarding the reciprocating operation of the tape unit 140, a post 141 coupled to the belt clamp member 119 protrudes upward through a long hole 123 formed in the upper table 120, and the tape unit 140 is attached to the upper end of the post 141. Yes. The driving of the tape unit 140 will be further described later with reference to FIG. The details of the tape unit 140 itself are omitted here.

FIG. 7 shows a mechanism from the drum cam on the camshaft to the front of the aperture pawl. FIG. 8 is a diagram for explaining the rotation operation of the aperture claw by the mechanism shown in FIG.

  In the drive mechanism using the cams of the conveying rocking levers 107a and 107b shown in FIG. 5, the cam plate 105a uses a disk in consideration of the rotational balance. The cam groove 106a has a substantially D shape surrounding the camshaft portion 103a. In the normal bundling operation state shown in FIG. 5, the conveying rocking lever 107a occupies the position closest to the camshaft 103. As the camshaft 103 rotates, it swings between a position further away from the camshaft 103 (a left position in the figure). The conveying rocking lever 107b also occupies the position closest to the camshaft 103 in the state shown in FIG. 5, but is different from the case of the conveying rocking lever 107a in the position sandwiching the camshaft 103. Along with the rotation of 103, it swings between a position farther from the camshaft (a right position in the figure).

  Of the pair of cam plates 105a and 105b, the cam groove 106a of one cam plate 105a has a phase difference of 180 degrees with respect to the rotation of the camshaft 103 with respect to the cam groove 106b of the other cam plate 105b. The reciprocating operation of one conveying rocking lever 107a and the reciprocating operation of the other conveying rocking lever 107b are alternated. Therefore, the conveying / throttle units 130a and 130b are indicated by arrows in FIG. Thus, they operate in opposite phases to each other (FIG. 4).

  FIG. 6 shows a tape unit advance / retreat mechanism 142 that advances and retracts the tape unit 140. 2 to 4, the tape unit advance / retreat mechanism 142 includes a tape unit advance / retreat servomotor 117, a drive pulley 144, a driven pulley 145, and a belt 118 wound around them.

A post 141 is provided. The belt 118 of the belt transmission mechanism 143 reciprocates by the output rotation of the tape unit advance / retreat servomotor 117, and the reciprocation is transmitted from the belt clamp 119 clamping the belt 118 to the tape unit plate 146 via the post 141. The tape unit plate 146 is reciprocated in the direction of the arrow.

  7 and 8 show an example of a drawing claw opening / closing mechanism 150 that opens and closes the drawing claw when the pillow package is bound with tape. A diaphragm claw drum cam 113 attached to the camshaft 103 is formed with a cam groove 114 on a cylindrical peripheral surface, and a cam follower 116 provided on a lever 115 is engaged with the cam groove 114. A pair of slide blocks 153a and 153b are slidably provided on the slide shaft 152 attached to the frame, and the lever 115 is fixed to a connecting shaft 154 that connects the slide blocks 153a and 153b. The lever 115 in which the cam follower 116 is engaged with the cam groove 114 of the drum cam 113 is moved in the axial direction of the camshaft 103 by the cam action of the cam groove 114 and the cam follower 116 as the camshaft 103 rotates, as indicated by an arrow. When moving, both slide blocks 153 a and 153 b move left and right on the slide shaft 152 while maintaining a distance from each other by the connecting shaft 154. Since both slide blocks 153a and 153b are provided with channel material cams 155a and 155b for opening and closing the aperture claws, respectively, both cams 155a and 155b are also indicated by arrows in accordance with the lateral movement of the lever 115. Move left and right.

  As shown in FIG. 8, the cams 155a and 155b attached to the slide blocks 153a and 153b correspond to the aperture claw units 160a and 160b respectively provided on both sides in the transport direction. Cams 155a and 155b attached to the slide blocks 153a and 153b shown in FIG. 7 are cam-engaged with cam followers 165a and 165b provided at the ends of levers 164a and 164b fixed to the shafts of the gears 161a and 161b. doing. Since the gears 161a and 161b to which the levers 164a and 164b are attached further mesh with the gears 162a, 163a and 162b and 163b, respectively, each having a pair of aperture claws 166a and 167a; When the levers 164a and 164b are rotated counterclockwise and clockwise in the figure by the cam action of the cams 155a and 155b and the cam followers 165a and 165b, the gears 161a to 163a; 161b to 163b are sequentially rotated in the direction of the arrow. Thus, the aperture claws 166a and 167a of the aperture claw unit 160a on one side are closed, and the aperture claw unit 160b on the opposite side is operated in reverse by the lever 164b rotating in the reverse direction. 167b performs an opening operation. When the cams 155a and 155b move in the direction shown in FIG. 8 (a), the aperture claw unit 160a on one side operates in the closing direction, and the aperture claw unit 160b on the opposite side operates in the opening direction. When 155b moves in the direction shown in FIG. 8B, the aperture claw unit 160a on one side operates in the opening direction, and the aperture claw unit 160b on the opposite side operates in the closing direction.
