As shown in FIG. 5, in the horizontal bag-making filling and packaging machine 1, the strip-shaped packaging material FwA (or FwB) is transferred from the original roll FrA (or FrB) wound in a roll shape to the paper feed roller 7 and paper. It is fed and supplied by the packaging material conveying device 3 provided with the pulling rollers 9 and 9. The strip-shaped packaging material FwA is curved and molded into a substantially tubular shape by the bag making device 8 and transferred horizontally, and the product P is sequentially delivered and supplied to the substantially tubular curved film by the supply conveyor 2 at predetermined intervals. The curved packaging material to which the product P is supplied is formed into a tubular packaging material Ft by center-sealing the overlapping surface of the end edge portion in the longitudinal direction with the center seal rollers 10 and 10 of the center seal device 4. Further, downstream of the center seal device 4, an end seal device 5 including end sealers 11 and 11 that normally perform rotation or box motion operations is arranged, and before and after the tubular packaging material Ft sandwiches the product P. The pillow package Bp is manufactured by performing end seals (which can be cut by a built-in cutter) by the end seal devices 5 at each position. Since the operation of the horizontal bag-making filling and packaging machine has been well known in the past, further detailed description thereof will be omitted.

The auto-splicer 6 ends when the strip-shaped packaging material FwA drawn from one of the two raw rolls FrA and FrB (referred to as FrA in the figure) as the packaging material supply source reaches the feeding end. The part is automatically connected to the starting end of the new strip-shaped packaging material FwB (referred to as "paper splicing") drawn from the other original roll (referred to as FrB in the figure), and the strip-shaped packaging material is continuously uninterrupted. This is an automatic paper splicing device for pulling out to the packaging material transport device 3. The auto splicer 6 shown in FIG. 5 includes cutter portions 41A and 41B for cutting the end portions of the raw fabric rolls FrA and FrB and the strip-shaped packaging materials FwA and FwB, and crimping roller portions arranged so as to face each other on the downstream side thereof. 42A and 42B are provided, and the cutter portions 41A and 41B and the crimping roller portions 42A and 42B are arranged symmetrically in the drawing.

As shown in FIGS. 5 and 6, the auto splicer 6 includes not only the cutter portions 41A and 41B and the crimping roller portions 42A and 42B, but also the roll holder shafts 43A and 43B on which the original rolls FrA and FrB are loaded. The upper surfaces of the guide portions 44A and 44B composed of a plurality of guide rollers 44aA and 44bA; 44aB and 44bB for guiding the traveling of the strip-shaped packaging materials FwA and FwB drawn from the original rolls FrA and FrB, respectively, and the strip-shaped packaging materials FwA and FwB The tables 45A and 45B are provided so as to run along the above. The original rolls FrA and FrB are set on the roll holder shafts 43A and 43B. The strip-shaped packaging materials FwA and FwB drawn from the original rolls FrA and FrB move horizontally on the tables 45A and 45B via the guide portions 44A and 44B composed of a plurality of guide rollers 44aA and 44bA; 44aB and 44bB. , Cutter portions 41A and 41B located at the ends of the tables 45A and 45B, and reach the crimping roller portions 42A and 42B.

Inside the tables 45A and 45B, suction boxes 46A and 46B are provided for suction holding of the band-shaped packaging materials FwA and FwB when stopped, guidance during running, and tension application, and the suction boxes 46A and 46B are provided. The table plates 48A and 48B, which are the front plates, have a large number of suction holes (not shown). The suction boxes 46A and 46B provided inside the tables 45A and 45B on which the strip-shaped packaging materials FwA and FwB travel suck air through the suction holes formed in the table plates 48A and 48B, whereby the strip-shaped packaging materials FwA and FwB is adsorbed on the tables 45A and 45B.

The crimping roller portions 42A and 42B are provided with crimping rollers 55A and 55B located opposite to each other, and guide rollers 56A and 56B on which the strip-shaped packaging materials FwA and FwB are hung are provided at the ends on the table 45A and 45B sides. ing. Suction boxes 47A and 47B are also provided inside the crimping roller portions 42A and 42B, and a large number of suction holes (not shown) are also provided in the suction boxes and the suction plates 54A and 54B which are the front plates of the 47A and 47B. It is formed. The strip-shaped packaging materials FwA and FwB are attracted not only by the table plates 48A and 48B of the tables 45A and 45B but also by the suction plates 54A and 54B of the crimping roller portions 42A and 42B by the suction action of the suction box. Adsorbing the strip-shaped packaging materials FwA and FwB on these plates 48A, 48; 54A and 54B acts as a resistance when any of the strip-shaped packaging materials FwA and FwB is run, and the strip-shaped packaging material FwA is routed downstream. , FwB is given an appropriate tension.

In the auto splicer 6 shown in FIG. 5, the strip-shaped packaging material from the original roll FrA used for packaging (the packaging material FwA is the old strip-shaped packaging material) is transferred from the table 45A to the downstream via the crimping roller portion 42A. The strip-shaped packaging material (the packaging material FwB is used as the new strip-shaped packaging material) from the raw fabric roll FrB that is drawn around and spliced to the paper is pulled out from the table 45B to the crimping roller portion 42B, and the starting end portion FSB is crimped. It stands by on the roller 55B. When the feeding of the old strip-shaped packaging material FwA is completed, the double-sided adhesive tape Ta is attached to the starting end portion FSB of the new strip-shaped packaging material FwB (the timing of attaching the double-sided adhesive tape Ta may be close to the paper splicing). With the adhesive tape Ta attached, the crimping roller portions 42A and 42B are rotated in opposite directions with the center position in the longitudinal direction as the center of rotation. The crimping rollers 55A and 55B approach each other, and the starting end FSB of the new strip-shaped packaging material FwB is interposed via the double-sided adhesive tape Ta near the end portion FEA of the old strip-shaped packaging material FwA (remaining portion Fs is left). Is crimped.

The auto splicer of this horizontal bag-making filling and packaging machine is provided with two horizontal table portions as described above, and a crimping roller portion that is connected to each table portion and is arranged and rotated, and each table portion. Since each crimping roller part is configured to have a suction function that attracts the strip-shaped packaging material, the table part and the crimping roller part have a suction function that sucks the band-shaped packaging material that is the packaging material to stabilize the running. Play. By the suction function of this table part, the strip-shaped packaging material is sucked from the back surface to the table part and tension is applied, so that the strip-shaped packaging material meanders even when it is peeled off from the paper tube. It is designed to prevent it from becoming. Further, the suction function of attracting the strip-shaped packaging material in the crimping roller portion can be realized by a suction plate having a large number of suction holes, and by sucking the starting end portion of the standby strip-shaped packaging material from the back surface thereof. , It is intended to prevent the starting end of the strip-shaped packaging material from flying up and curling. This eliminates the need to dispose a pressing member or a pressing brush above the strip-shaped wrapping material, which makes it possible to easily set the strip-shaped wrapping material on the table portion and the crimping roller portion, and at the time of paper splicing. We are trying to prevent the occurrence of misalignment of the pattern.

However, although the auto splicer of this horizontal bag-making filling and packaging machine is an auto splicer improved as described above, the crimping rollers provided at the tip portions of the two crimping rollers are in a non-crimping state. Even if they are, they are arranged so that they are close to each other. That is, since the space between the two crimping roller portions is a V-shaped space closer to the tip portion when viewed from the side, the space is very narrow in the vicinity of the crimping roller portion. It is necessary to set the starting end of the new strip-shaped packaging material in the vicinity of the crimping roller where the space is narrowed, but at that time, the operator's finger or the tip of the strip-shaped packaging material is caught between the crimping rollers. There is a risk. In addition, when setting an opaque strip-shaped wrapping material such as an aluminum vapor-deposited film, the worker is in a state of looking at the back surface of the strip-shaped wrapping material. It is necessary to pay close attention to the position of the old and new strip-shaped wrapping materials, such as turning over the strip-shaped wrapping material to prevent the pattern from shifting, which is extremely troublesome and requires paper splicing work. The sex may not be good.

Therefore, in the auto splicer of the horizontal bag-making filling and packaging machine in which the table portion and the crimping roller portion tiltably connected to the table portion are arranged in pairs facing each other, waiting for paper splicing. By making it possible to change the setting posture of the starting end of the strip-shaped packaging material inside, the safety of the setting work when joining the strip-shaped packaging material is further improved, and the new strip-shaped to be joined. There is a problem to be solved in terms of making it easier to determine the position of the tip of the packaging material and further improving the workability of the paper splicing.

An object of the present invention is to solve the above problems, and to eliminate the risk that the operator's finger or the tip of the strip-shaped wrapping material may get caught between the crimping rollers when the strip-shaped wrapping material is spliced. By making the work safer, eliminating the need to position the tip of the new strip-shaped wrapping material to be spliced in a narrow space, and preventing the connection where the printed pattern is misaligned, it is possible to set the paper splicing. It is to provide an auto splicer of a horizontal bag-making filling and packaging machine capable of further improving workability.

In order to solve the above problems, the auto splicer of the horizontal bag-making filling and packaging machine according to the present invention includes a table portion having a feed guide surface capable of guiding the feed of the strip-shaped packaging material delivered from the strip-shaped packaging material supply source. Two sets of packaging material feeding assemblies each including a crimping roller portion having a working surface capable of guiding the feeding of the strip-shaped packaging material and supporting the strip-shaped packaging material following the feeding guide surface of the table portion. The crimping roller portions are arranged in pairs in a manner in which the crimping roller portions face each other, and each crimping roller portion is arranged at an end portion on the table portion side and is a guide roller for winding and guiding the strip-shaped packaging material. A crimping roller on which the strip-shaped packaging material, which is arranged at the end far from the table portion and is guided and sent to the work surface, is hung, and a roller that rotatably supports the guide roller and the crimping roller. A roller unit having a frame, a work plate having the work surface and having a large number of suction holes formed in the work surface, and the strip-shaped packaging material provided integrally with the work plate and through the suction holes. The work / suction unit having a suction box that exerts a suction action on the work / suction unit, and the work / suction unit are rotatably supported by the roller frame, and the work / suction unit can be tilted by the rotation. It is composed of a rotation support structure that can be fixed by selecting one of the operating position and the flipped up working position.

According to the auto splicer of this horizontal bag-making filling and packaging machine, the strip-shaped packaging material is unwound from one of the strip-shaped packaging material supply sources by winding the strip-shaped packaging material, and the strip-shaped packaging material is delivered by the packaging operation of the horizontal bag-making filling and packaging machine. When the situation is such that the new strip-shaped packaging material should be spliced with paper due to the consumption of the paper, the old strip-shaped packaging material to be spliced is tilted at one of the crimping rollers. In the other crimping roller part, the work / suction unit is held on the work surface of the work / suction unit, and the work / suction unit is flipped up by the rotation operation of the rotation support structure. Work in which the tip of the packaging material takes a working position ・ Work in which the suction unit is positioned and held on the work surface of the suction unit, and the new band-shaped packaging material is sucked and held ・ The suction unit is tilted by the rotational operation of the rotation support structure. When both crimping rollers move closer to each other by rotating the roller frame in the flip-up direction in both crimping roller portions, the starting end portion of the new band-shaped packaging material on the other crimping roller is on one side. By crimping the old strip-shaped packaging material on the crimping roller of the above, the new strip-shaped packaging material is spliced to the old strip-shaped packaging material. That is, if a new strip-shaped packaging material is set for the work / suction unit that occupies the work position and the work / suction unit is returned to the operation position, the subsequent paper splicing operation is automatically performed.

In the auto splicer of this horizontal bag-making filling and packaging machine, the rotation support structure is provided in relation to a support shaft that rotatably supports the guide roller, and the work / suction unit is the rotation support. By rotating around the support shaft according to the structure, the operating position along the roller frame and the working position that jumps up from the roller frame so that the working surface is flush with the feed guide surface of the table portion. It consists of being able to select any of the positions.
By providing a rotary support structure related to the support shaft that rotatably supports the guide roller, the work surface of the work / suction unit is the same as the peripheral surface of the guide roller even if it rotates with respect to the guide roller. Since the connections are made in an angle relationship, the strip-shaped packaging material is well guided from the peripheral surface of the guide roller to the work surface of the work / suction unit.
Also, when the work / suction unit is flipped up to take the work position, the feed guide surface of the table and the work surface of the work / suction unit are flush with each other, so the new strip-shaped packaging material is fed from the feed guide surface. It can be extended straight to the work surface, facilitating the setting work of new strip-shaped packaging material.

In the auto splicer of this horizontal bag-making filling and packaging machine, at least the work surface of the feed guide surface of the table portion and the work / suction unit of the crimping roller portion is formed on the strip-shaped packaging material. At least one index such as a cash register mark for positioning the feeding direction of the strip-shaped packaging material or an engraving that can be contrasted with a specific part of the pattern can be provided.
By providing at least such an index on the work surface, it is possible to easily determine at least the position of the strip-shaped packaging material in the feeding direction on the work surface when setting the strip-shaped packaging material. By providing a plurality of indexes, one index is used as a cutting position for cutting a new strip-shaped packaging material to form a starting end portion, and the cut starting end portion is used as an index closer to the next crimping roller. By moving to and positioning the strip-shaped wrapping material, it is possible to more accurately splice the strip-shaped wrapping material so that the pattern does not deviate from the old strip-shaped wrapping material.

In the auto splicer of this horizontal bag-making filling and packaging machine, the table portion has a suction hole formed in the feed guide surface with respect to the strip-shaped packaging material on the feed guide surface, and the suction hole is passed through. A suction unit for exerting a suction action can be provided.
The table portion also forms a suction hole that opens in the feed guide surface, and the suction unit sucks and holds the strip-shaped packaging material through the suction hole, so that the work surface of the work surface of the work surface of the work surface of the crimping roller portion is sucked and held. , The holding of the strip-shaped packaging material can be further ensured. It is preferable that the suction unit provided on the table portion and the suction unit provided on the crimping roller portion can be operated separately.

In the auto splicer of this horizontal bag-making filling and packaging machine, it corresponds to the operation when the work / suction unit of the crimping roller portion is changed from the work position to the operation position by rotation by the rotation support structure. Therefore, since the new strip-shaped packaging material that is attracted and held on the work surface of the work / suction unit is provided with a small feed mechanism that slightly feeds the new strip-shaped packaging material so that its starting end portion protrudes beyond the crimping roller. It is made up.
By providing a small feed mechanism, when the work / suction unit of the crimping roller is changed from the work position where it is flipped up to the tilted operation position, the start end of the new band-shaped packaging material is changed to the crimp roller. It will be slightly pushed over. For example, if double-sided tape is attached to this protruding part, when both crimping rollers approach each other due to the rotational movement of the roller frame, the starting end of the new strip-shaped packaging material becomes the old strip-shaped packaging material via the double-sided tape. It is crimped and the old and new strip-shaped wrapping materials are firmly adhered with double-sided tape, so that the paper joint can be ensured.

In the auto splicer of this horizontal bag-making filling and packaging machine, the operation by the small feed mechanism is changed from the work position to the operation position by the work / suction unit of the crimping roller portion by the rotation support structure. It can be a passive operation by mechanically converting.

Use it to do it. That is, since the operation of the small feed mechanism can be passively obtained by mechanically converting the rotation operation when the position is changed, a drive source only for the small feed mechanism is provided and actively operated. It is not necessary, and the structure of the small feed mechanism can be simplified and the manufacturing and operating costs can be reduced.

In the auto splicer of this horizontal bag-making filling and packaging machine, the work / suction unit is movably supported by the crimping roller portion in a direction parallel to the strip-shaped packaging material feed guide direction of the work surface with respect to the roller frame. The small feed mechanism includes a lever rotation shaft supported by the roller frame at a position away from the rotation center of the rotation support structure, and a suction unit support pin provided on the work / suction unit. When the work / suction unit of the crimping roller portion is in the operating position, the suction unit support lever is rotatably connected to the lever rotation shaft and the suction unit support pin. It can be assumed that the rotation center of the rotation support structure, the axis of the lever rotation shaft, and the pin axis of the suction unit support pin are on one straight line.
Work of the crimping roller part ・ When the suction unit is in the flip-up state, the rotation center of the rotation support structure, the axis of the lever rotation axis, and the pin axis of the suction unit support pin are at the apex of the triangle. There are each, and the pin axis of the suction unit support pin, and therefore the work / suction unit, is moved toward the rotation support structure side (retracted position of the suction unit support pin). When the work / suction unit is changed from the work position to the inclined operating position, the pin axis of the suction unit support pin, and therefore the work / suction unit moves to the crimping roller side (advance position of the suction unit support pin), and the work -The strip-shaped packaging material adsorbed on the suction unit is pushed out from the crimping roller by the amount of movement.

The suction unit support pin is movable along the first elongated hole formed in the work / suction unit of the crimping roller portion in a manner extending in the strip-shaped packaging material feed guide direction, and the crimping roller portion is said to have the same. In the work plate having a work surface, a plurality of second elongated holes are formed in a manner extending in the strip-shaped packaging material feed guide direction, and the work / suction unit has a plurality of suctions in which the suction holes are opened. The convex portion is arranged in the second long hole, and the suction convex portion moves in the second long hole in response to the movement of the suction unit support pin along the first long hole. It consists of doing.
According to this auto splicer, in the work / suction unit, a plurality of suction protrusions arranged in the second elongated hole open the suction hole on the work surface of the work plate, and are band-shaped through the suction hole. It exerts a suction action on the packaging material. When the work / suction unit of the crimping roller is changed from the work position in the flip-up state to the operation position in the tilted state, the suction unit support pin moves along the first elongated hole to move the work / suction unit. It is possible to move along the strip-shaped packaging material feed guide direction inside the work plate, and by moving the work / suction unit, the strip-shaped packaging material sucked by the work / suction unit can be small-fed. Using the rotational movement when the work / suction unit changes from the work position to the operating position, the additional feeding of the strip-shaped packaging material in the crimping roller portion of the strip-shaped packaging material has a simple structure such as a pin, an elongated hole, and a lever. It can be obtained by the mechanism.

Since the auto splicer in the horizontal bag-making filling and packaging machine according to the present invention is configured as described above, a paper splicing is applied to the new band-shaped packaging material by completing the feeding of the band-shaped packaging material from one of the packaging material rolls. When the situation should be reached, in the other assembly consisting of the other table part and the other crimping roller part, the position of the work / suction unit of the other crimping roller part is bounced from the operating position in the inclined state. When the working position is changed to the raised working position, the crimping roller of the other crimping roller that takes the working position takes a position away from the crimping roller of one crimping roller, so that the space around the other crimping roller is widely opened. Will be done. Further, in the other assembly, it is safe and easy to set the new band-shaped packaging material including the tip portion on the feed guide surface of the table portion and the work surface of the crimping roller portion without being disturbed by one assembly. become. In the other assembly in which the new band-shaped packaging material is set, the position of the work / suction unit of the crimping roller portion is changed to the operating position. By moving the roller frame of both crimping rollers in the flip-up direction, the tips of the new strip-shaped wrapping material are automatically crimped to the old strip-shaped wrapping material by both crimping rollers approaching each other, and paper splicing is performed. .. Therefore, while both crimping rollers occupy the inclined operating position, both crimping rollers are close to each other and the space between both crimping rollers is narrowed. However, the crimping roller part to which the new strip-shaped packaging material should be set By placing the work / suction unit in the flipped-up work position, the hands and fingers of the worker are prevented from being pinched, the safety of the paper splicing work is improved, and the work in a narrow space is eliminated, so the paper splicing work The sex can be improved. Further, the position of the starting end portion of the new strip-shaped packaging material in the assembly is predetermined in the work / suction unit before crimping, preferably in the flip-up state, in accordance with the position of the old strip-shaped packaging material on the work surface. Even with an opaque strip-shaped wrapping material, it is possible to obtain a state in which a pattern or a printed pattern is aligned at the time of paper splicing.

A pipe joint 27a connected to an appropriate negative pressure source is attached to the suction box 24, and an air passage 27b connected to the pipe joint 27a is formed in the suction box 24. A plurality of suction convex portions 28 arranged in the width direction of the crimping roller portion 14 are formed so as to project from the suction box 24. A suction hole connected to the air passage 27b is formed in the suction convex portion 28, and the suction hole is opened at the tip of the suction convex portion 28. A plurality of second elongated holes 29 extending in the feed direction of the strip-shaped packaging material Fw are formed in the work plate 22 of the workbench 21 corresponding to each of the plurality of suction convex portions 28, and protrude from the suction box 24. Each suction convex portion 28 is fitted and arranged in the corresponding second elongated hole 29. The tip of the suction convex portion 28 through which the suction hole opens is flush with the work surface 22a of the work plate 22.

The suction box 24 moves while being guided by the first elongated hole 26 formed in the work plate support 23 by the suction unit support pin 25 on each side in the width direction, whereby the strip-shaped packaging material Fw is moved with respect to the work table 21. In response to the sliding operation, each suction convex portion 28 of the suction box 24 moves in the second elongated hole 29 formed in the work plate 22. Even when the suction convex portion 28 moves in the second elongated hole 29, the suction hole of the suction convex portion 28 is always open flush with the work surface 22a, so that the suction box 24 operates by suction. When it is present, the strip-shaped packaging material Fw on the work surface 22a of the work plate 22 can be sucked and held by exerting a suction action on the strip-shaped packaging material Fw. Therefore, the suction box 24 can move in the feeding direction of the strip-shaped packaging material Fw along the work plate 22 while exerting a suction action on the strip-shaped packaging material Fw.

The axial position of the roller shaft 19a of the guide roller 17 is fixedly arranged on the machine frame of the packaging machine in the vicinity of the table portion 13, but the work / suction unit 20 has a rotation support structure on the roller shaft 19a. 30 attaches the roller shaft 19a so as to be rotatable around the roller shaft 19a and fixed at a predetermined rotation position. That is, a housing 31 having a cylindrical structure is fixedly attached to the end of the roller frame 16 on the table portion 13 side, and the roller shaft 19a penetrating the roller frame 16 also penetrates the cylindrical structure of the housing 31. It is extending. Regarding the workbench 21, on each side in the width direction, the work plate support 23 is rotatably attached to the roller shaft 19a, while the work plate 22 advances and retreats with respect to the housing 31. A possible fixed plunger 32 is screwed in. The housing 31 is formed with at least two pin fitting holes 33a and 33b for selectively accepting the tip pin of the fixing plunger 32 in order to selectively fix the posture / state that the work / suction unit 20 can take. There is.

According to the rotation support structure 30 having the above structure, in the crimping roller portion 14, the housing 31 and the structures related thereto (fixed plunger 32, pin fitting holes 33a, 33b, etc.) are provided with respect to the roller frame 16. The work / suction unit 20 (work plate 22, work plate support 23, suction box 24, etc.) is rotatably supported around the roller shaft 19a, and the posture of the work / suction unit 20 can be changed. By selectively fitting the fixed plunger 32 penetrating the work plate 22 into any of the pin fitting holes 33a and 33b formed in the housing 31, the work / suction unit 20 is placed in the work position (posture in the flip-up state). ) And the operating position (tilted posture) can be selected and held / fixed. In the state shown in FIG. 1B, the fixed plunger 32 is fitted in the fitting hole 33a, and the crimping roller portion 14 is actually in the inclined operating position (P1). When the crimping roller portion 14 is rotated around the roller shaft 19a (rotated counterclockwise in the figure) to reach the working position (P2) in the flip-up state, the fixed plunger 32 is fitted into the fitting hole 33b. By matching, the crimping roller portion 14 is fixed and held at the working position (P2).

In the auto splicer, during the normal packaging operation, the two packaging material feed assemblies 12 and 12 face each other in an inclined state with the crimping roller portions 14 and 14 as shown in FIG. In each crimping roller portion 14, the working / suction unit 20 is in an inclined posture along the roller frame 16, that is, in the operating position P1 (see FIG. 2). From that state, at the time of paper splicing, in one packaging material feed assembly body 12, only the work / suction unit 20 is flipped up at the work position P2 (while leaving the roller frame 16 and the crimping roller 18 at the operating position). (See Fig. 2). At this time, the work / suction unit 20 does not interfere with the crimping roller portion 14 in the inclined state of the packaging material feed assembly body 12 on the other side. The new strip-shaped packaging material Fw can be positioned and held in the flipped-up work / suction unit 20. Paper splicing can be performed by returning the work / suction unit 20 from the work position P2 to the operation position P1 and bringing the crimping rollers 18 and 18 closer to each other.

FIG. 2 is an enlarged view of a part of the auto splicer shown in FIG. 1. A working position P2 in which the working / suction unit 20 is flipped up to a horizontal position and an operating position P1 in an inclined state. Are shown by solid lines. FIG. 2 does not show the roller unit 15 and the rotation support structure 30. The crimping roller portion 14 includes a small feed mechanism 34 that feeds the new strip-shaped packaging material Fw slightly ahead by the rotation of the work / suction unit 20 to push it out from the crimping roller 18 at the time of paper splicing.

The small feed mechanism 34 includes a lever rotation shaft 35 attached to a roller frame 16 (not shown in FIG. 2), a suction unit support pin 25 provided on the suction box 24, and a lever rotation shaft 35 and a suction unit support. A suction unit support lever 36 rotatably connected to the pin 25 is provided. The lever rotation shaft 35 is supported on the roller frame 16 at a position separated by a distance L1 from the rotation center (axis line of the roller shaft 19a) of the rotation support structure 30.

When the crimping roller portion 14 is in the working position P2 in the flip-up state, the rotation center of the roller shaft 19a, the axis of the lever rotation shaft 35, and the pin axis of the suction unit support pin 25 are located at the apex of the triangle. The pin axis of the suction unit support pin 25, that is, the suction box 24 is moved toward the roller shaft 19a. The work / suction unit 20 at the work position P2 is lined up on an extension line of the table unit 13, and the feed guide surface 48 (see FIG. 6) of the table unit 13 and the work surface 22a of the work / suction unit 20 are flush with each other. It becomes a state. By making the work surface 22a flush with the feed guide surface 48, the new strip-shaped packaging material Fw can be extended straight from the feed guide surface 48 of the table portion 13 to the work surface 22a of the work plate 22, and the strip-shaped packaging material can be extended. The setting work of the Fw on the work surface 22a becomes easy. The length of the suction unit support lever 36, that is, the distance between the axis of the lever rotation shaft 29 and the pin axis of the suction unit support pin 25 is L2, and the rotation center of the roller shaft 19a and the suction unit support pin 25 If the distance between the pin axis and the pin axis is L3, the distance L3 is shorter than the length (L1 + L2). Therefore, the suction unit support pin 25 takes a position closer to the roller shaft 19a in the first elongated hole 26 formed in the work plate support 23, and the suction box 24 occupies a position closer to the roller shaft 19a.

When the work / suction unit 20 is rotated around the roller shaft 19a and the posture is changed from the work position P2 in the flip-up state to the operation position P1 in the tilted state, the rotation center of the roller shaft 19a and the lever rotation shaft 35 And the pin axis of the suction unit support pin 25 are aligned on one straight line. At this time, the distance L3 between the rotation center of the roller shaft 19a and the pin axis of the suction unit support pin 25 is the maximum length (L1 + L2), and the suction unit support pin 25 is formed on the work plate support 23. The suction box 24 occupies a position closer to the crimping roller 18 in the first elongated hole 26. Therefore, the suction box 24 has a crimping roller 18 along the work plate 22 when the work / suction unit 20 is rotated to change the posture from the work position P2 in the flip-up state to the operation position P1 in the tilted state. The suction convex portion 28 of the suction box 24 moves to the side, and moves to the crimping roller 18 side in the second elongated hole 29. The strip-shaped packaging material adsorbed on the suction convex portion 28 is fed while being guided along the feed guide surface 48 and the work surface 22a by the amount of movement (L1 + L2-L3), and the predetermined tip portion of the strip-shaped packaging material Fw is fed. The length is pushed out from the crimping roller 18 first.

By providing the small feed mechanism 34, when the work / suction unit 20 is rotated from the work position P2 to the operation position P1 by the rotation support structure 30, the new strip-shaped packaging material moves while being sucked, and its starting end. The predetermined length of the portion side protrudes from the crimping roller 18 first. If, for example, double-sided tape is attached to this protruding portion, both crimping rollers 18 and 18 can be formed by slightly rotating the roller frames 16 and 16 of both packaging material feed assemblies 12 and 12 on opposite sides. When they approach each other, the starting ends of the new strip-shaped wrapping material are crimped to the old strip-shaped wrapping material via the double-sided tape, and the old and new strip-shaped wrapping materials can be adhered by the double-sided tape, that is, the paper joint can be ensured. The operation of the small feed mechanism 34 is a passive operation obtained by mechanically converting the rotation operation of the work / suction unit 20 (the operation of changing the position from the work position P2 to the operation position P1). Operation. As a result, it is not necessary to provide a drive source only for the small feed mechanism 34, the structure of the small feed mechanism 34 can be simplified, and the manufacturing and operating costs of the auto splicer can be reduced. When it is permitted to use an appropriate other drive source such as an air cylinder, the operation of the small feed mechanism 34 may be an active operation that is operated in accordance with the attitude change by the drive source.

FIG. 3 is a diagram illustrating the operation of the auto splicer in this horizontal bag-making filling / packaging machine, that is, the paper joining process of the strip-shaped packaging material. In one of the crimping roller portions 14 shown in FIG. 3A, the work / suction unit 20 is at the operating position P1 inclined along the roller unit 15, but the old strip-shaped packaging material Fwo is placed on the work / suction unit 20. It is in a state where the feeding supply is finished as it is. In the crimping roller portion 14 on the Fwo side of the old strip-shaped packaging material, reference numerals are omitted for simplification of the drawings. On the other hand, in the crimping roller portion 14 on the (new strip-shaped packaging material Fwn) side, a step of lifting the fixing plunger 32 and removing the tip of the fixing plunger 32 from the pin fitting hole 33b of the housing 31 is shown. In the crimping roller portion 14, the new strip-shaped packaging material has not yet been placed in the work / suction unit 20. By removing the fixed plunger 32 from the pin fitting hole 33b, the crimping roller portion 14 can be rotated around the roller shaft 19a by the rotation support structure 30, from the work plate 22, the work plate support 23, and the suction box 24.・ The suction unit 20 can be flipped up around the roller shaft 19a.

FIG. 3B shows that the work / suction unit 20 occupies the work position P2 in the flip-up state in the other crimping roller portion 14. By fitting the fixed plunger 32 into another pin fitting hole 33a of the housing 31, the working / suction unit 20 is maintained in a state of occupying the working position P2. Further, in the small feed mechanism 34, when the work / suction unit 20 jumps up, the suction unit support pin 25 is restricted by the first elongated hole 26 and lifted, and at the same time, the suction unit support lever 36 moves to the lever rotation shaft. Rotating around 35, the suction unit support pin 25 moves in the first elongated hole 26 toward the roller shaft 19a, that is, toward the upstream side in the feeding direction of the strip-shaped packaging material Fw. Therefore, the work / suction unit 20 is moved to the upstream side in the feed direction of the strip-shaped packaging material Fw at the other crimping roller portion 14.

FIG. 3C shows a step of setting the new strip-shaped packaging material Fwn in the work / suction unit 20 occupying the work position P2 in the other crimping roller portion 14. The new strip-shaped packaging material Fwn is pulled out from the table portion 13 (see FIG. 4) and set on the work surface 22a of the work / suction unit 20 of the crimping roller portion 14. Regarding the set of the new band-shaped packaging material Fwn, it is preferable to set the position of the start end portion FSB using an index (described later) provided on the table portion 13 or the crimping roller portion 14 as a mark.

FIG. 3D shows a state in which the new strip-shaped packaging material Fwn is set in the work / suction unit 20 occupying the work position P2 in the other crimping roller portion 14. A double-sided tape Ta is attached in the immediate vicinity of the starting end portion FSB of the new strip-shaped packaging material Fwn in order to adhere to the old strip-shaped packaging material Fwo. Since the space above the work / suction unit 20 is in an open state, it is safer to attach the double-sided tape Ta than when the new strip-shaped packaging material Fwn is set in the inclined state shown in FIG. 3 (a). And it is easy to do. In the rotation support structure 30, the work / suction unit 20 can be rotated around the roller shaft 19a by lifting the fixed plunger 32 again and removing the tip of the fixed plunger 32 from the pin fitting hole 33a of the housing 31. To do. At this time, the suction box 24 is subjected to a suction operation to suck and hold the new strip-shaped packaging material Fwn on the work surface 22a.

FIG. 3E shows a process in which the work / suction unit 20 is returned from the work position P2 in the flip-up state to the operation position P1 in the tilted state in the other crimping roller portion 14. After rotating the work / suction unit 20 around the roller shaft 19a to an inclined state, the tip of the fixed plunger 32 is fitted into the initial pin fitting hole 33b of the housing 31, so that the work / suction unit 20 is formed. It is locked to the original tilted operating position P1. In the small feed mechanism 34, the suction unit support lever 36 rotates around the lever rotation shaft 35, so that the suction unit support pin 25 moves in the first elongated hole 26 in the feed direction of the new strip-shaped packaging material Fwn. To do. Since the suction box 24 supported by the suction unit support pin 25 also moves by the amount of movement (L1 + L2-L3), the new strip-shaped packaging material Fwn sucked and held by the suction convex portion 28 of the suction box 24 is fed by that amount. Small feed in the direction. The suction convex portion 28 moves in the second elongated hole 29 of the work plate 22 by the same amount in the packaging material feeding direction.

FIG. 3 (e) shows a state in which the starting end portion FSB of the new strip-shaped packaging material Fwn protrudes from the crimping roller 18. In this state, by rotating both the crimping roller portions 14 and 14 in the direction of the flip-up state, the crimping rollers 18 and 18 approach each other, and the starting end portion FSB of the new band-shaped packaging material Fwn is interposed via the adhesive tape Ta. Is automatically crimped to the old strip-shaped packaging material Fwo to perform paper splicing. As a means for rotating the crimping roller portions 14, 14, for example, two sector gears having rotation centers on the roller shafts 19a and 19a are meshed with each other, and the sector gears are rotated by an appropriate driving means (air cylinder). It can be a structure to make it. According to this auto splicer, even when the old band-shaped packaging material Fwo is set as the new band-shaped packaging material Fwen in the past, the start end FSB is small-fed by the operation of the small feed mechanism 34, and the small-fed band-shaped packaging is provided. Feed control is performed for the material Fw according to the specifications of the bag package. Therefore, even when the new strip-shaped wrapping material Fwn is spliced with paper this time, the paper splicing is performed on the old strip-shaped wrapping material Fwo to which the start end FSB has already been slightly fed, so that the pattern pattern shifts even after the paper splicing. It never happens.

As shown in FIG. 2, at least the work surface 22a of the feed guide surface 48 (see FIG. 6) of the table portion 13 and the work surface 22a of the work / suction unit 20 is for positioning the strip-shaped packaging material Fw in the feed direction. At least one index (mark) 37 such as a stamp of is provided. The index 37 is for making it possible to compare with a specific part of the cash register mark or the pattern displayed on the strip-shaped packaging material Fw. By providing such an index 37, it is possible to easily determine the position of the strip-shaped packaging material Fw in the feeding direction at least on the work surface 22a when the strip-shaped packaging material Fw is set. When a plurality (for example, two) indexes 37 are provided according to the specifications of the packaging material, a new band-shaped packaging material is provided in one index 37 on the upstream side (for example, engraved on the feed guide surface of the table plate 48). Fw is cut with a cutter and used as the cutting position of the starting end FSB, and the cut starting end FSB is moved by the length of one bag and positioned at the index 37 closer to the next crimping roller 18 to join the paper. It is possible to splice the paper more accurately so that the pattern does not shift at the time of.
