Description

Technical Field

[0001] The present invention relates to an improved technology of a horizontal rotary automatic filling and packaging machine for manufacturing a packaged product by dividing a long packaging film (resin film) conveyed horizontally into a number of bag portions and filling each bag portion arranged horizontally with contents.

Background Art

[0002] Conventionally, there is a horizontal rotary automatic filling and packaging machine as one of the automatic filling and packaging machines that use a long packaging film (resin film) to divide and package contents such as powders quantitatively measured into a number of packages.

[0003] In this horizontal rotary automatic filling and packaging machine, for example, as described in Patent Document 1 and Patent Document 2, while pulling out and moving the packaging film horizontally from a film coil in which a packaging film or the like is wound around a core material, in the film guide portion, the packaging film is folded in two in a direction substantially orthogonal to the film traveling direction to form a portion that becomes the bottom of the bag portion, and the packaging film is introduced into the turntable.

[0004] A number of side seal bars arranged around on the turntable rotate at a speed synchronized with the introduced packaging film, and by sandwiching the packaging film from the vertical direction, a width seal (side seal: heat seal) extending in the vertical direction of the moving direction is formed for the packaging film moving (rotating and moving) in the horizontal direction.

[0005] Then, a plurality of filling shoots are inserted corresponding to the spaces between adjacent side seal bars among the sequentially folded packaging films (bag portions with upper openings), and rotate in synchronization with the packaging film and the side seal bars. The filling shoots are filled (loaded) with a predetermined amount of contents (powders, granular materials), then the filling shoots are removed from the bag portions, and the side seal bars holding the resin film are removed.

[0006] The packaging film thus filled with the contents in each bag portion is then top-sealed (heat-sealed) at the upper edge of the bag portion to be sealed. In this state, the width seal portion between the bag portions is cut or perforated along the longitudinal direction to obtain the required packaging form.

Summary of the Invention

Problems to be Solved by the Invention

[0008] Here, in a horizontal rotary automatic filling and packaging machine that has conventionally operated at high speed, in order to improve the product quality by making the cut portion of the packaging bag neat, a method has been used in which the packaging bag is pulled to give tension to the film and then cut or perforated. Specifically, by making the interval between the clips (144) of the clamp conveying device that grips and conveys the packaging bag (F4) slightly longer (L1) than the interval between one package (L) during cutting, tension is applied to the cut portion (side seal portion) (L2) of the packaging bag to perform a high-quality and stable cut (see FIGS. 2(A) to (C)).

[0009] However, when perforating between the packaging bags of the continuous packaging by this method, there is a problem that as the number of connections of a set of continuous packaging cut every predetermined number of packaging bags increases, the actual perforation position shifts (lags) to the right with respect to the set position (target position) of the perforation. With the recent further increase in speed, such problems have become prominent.

[0010] Generally, the perforating device for making perforations is configured to operate so as to make perforations at a set position (C1) which is the central position of the side seal at intervals of one bag in synchronization with the bag-making conveyance of the packaging bag.

[0011] However, in order to suppress the shaking of the continuous body of the packaging bag (continuous packaging bag F4) as the conveyance speed increases, the clamp conveyance device applies tension to the continuous body of the packaging bag and conveys it while pulling. Therefore, the installation position (C1) where the perforations should be made will be slightly extended more than the interval of one bag. For this reason, it is considered that a deviation (L3) occurs in the perforation position (C2) by that amount (see Fig. 2(C)).

[0012] When cutting one packaging bag at a time, this is a slight deviation within the allowable error level, so it did not pose a major problem. However, when a plurality of packages are connected, the deviation accumulates and increases by the length of the perforations, which has become a major problem in terms of product quality.

[0013] The present invention has been made in view of such circumstances, and when making perforations while pulling a continuous packaging bag or cutting at every predetermined number of bags, it prevents the perforation position and the cutting position from shifting cumulatively, and aims to provide a horizontal rotary type automatic filling and packaging machine capable of maintaining high product quality.

Means for Solving the Problems

[0014] Therefore, the horizontal rotary type automatic filling and packaging machine according to the present invention includes a side seal device that performs heat sealing in the width direction on a packaging film whose central portion is bent while being transferred in the horizontal direction, a filling chute that inputs contents into the packaging film bag portion divided by this side seal device, a turntable that rotates a plurality of arranged side seal devices and filling chutes, a top seal device that performs heat sealing on the upper edge of the packaging film bag portion filled with contents, A clamp conveyor device that grips and conveys a part of the top seal of the completed continuous packaging bag one by one with a clamp, A cutter device that cuts the side seal of the conveyed continuous packaging bag at a preset position to form a connected packaging bag in which a predetermined number of packaging bags are connected in series, A control device including an operation panel capable of setting the cutting position of the side seal of the continuous packaging bag, A horizontal rotary type automatic filling and packaging machine equipped with, In the clamp conveyor device, the clamps are arranged without end at intervals slightly longer than the product length of each continuous packaging bag, The cutting position for each bag of the cutter device with respect to the reference value A cutting position correction amount that can be shifted by a set distance can be set, and the cutter device is controlled so that the control device corrects the cutting position based on the cutting position correction amount. It is characterized by this.

[0015] In the present invention, A perforating device for making perforations in the side seal of the continuous packaging bag is provided upstream of the cutter device in the conveying direction, The cutting position correction amount is also applied to the perforation position made by the perforating device, and is cumulatively set for each perforation position within the range of one connected packaging bag. When cut and separated by the cutting device, this cumulative cutting position correction amount is reset. It can be characterized by this.

Effects of the Invention

[0016] According to the present invention, when making perforations while pulling the continuous packaging bag or cutting at every predetermined number of bags, it is possible to prevent the perforation position and the cutting position from shifting cumulatively, and it is possible to provide a horizontal rotary type automatic filling and packaging machine that can maintain high product quality.

Embodiments for Carrying out the Invention

[0018] Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the present invention is not limited by the embodiments described below.

[0019] First, the overall configuration of the horizontal rotary type automatic filling and packaging machine according to the present invention will be described with reference to FIG. 1. FIG. 1(A) is a front view (partial cross-sectional view) showing the horizontal rotary type automatic filling and packaging machine according to the present invention, and FIG. 1(B) is a plan view of the conveyance path of the packaging film as viewed from above. As shown in Fig. 1(A), the horizontal rotary automatic filling and packaging machine 1 includes a packaging film reel support shaft (in use) 3 rotatably supported by a main body 2, a packaging film reel support shaft (standby) 4 for the next use (spare), a packaging material feeding device 5, a packaging film folding guide (bag making guide) 6, a side seal device (side seal bar) 7, a filling chute 8, a content storage hopper 9, a weighing device 10, a preheating device 11, a top seal device 12, a notch device 13, a clamp conveying device 14, a perforation device 15, a cutter device 16, a first carry-out sliding table 17, a second carry-out sliding table 18, and an operation panel (control device) 19. The side seal device (side seal bar) 7, the filling chute 8, etc. are attached to a turntable 20 that rotates around the end of the main body in the horizontal plane.

[0020] The packaging film is wound in a roll as a packaging film reel F1 and supported by the packaging film reel support shaft 3. Also, the remaining part of the packaging film reel F1 is the spare packaging film reel F1' supported by the packaging film reel support shaft 4. Here, the packaging film is made of a transparent or semi-transparent material, and is composed of, for example, a base film such as PET and a heat-seal film such as polyethylene with a melting point lower than that of this base film. Further, the packaging film F1 may have a three-layer structure of a base film, an intermediate film, and a heat-seal film.

[0021] The packaging film F2 drawn from the packaging film reel F1 supported by the packaging film reel support shaft 3 passes through the packaging material feeding device 5 and is then continuously sent in the right direction in Fig. 1(A) and is folded into two along the central part in the longitudinal direction by the bag making guide (packaging film folding guide) 6 to form an upwardly open U shape. The folded packaging film F2 is introduced into the turntable 21 from the tangential direction of the turntable 20 as shown in Fig. 1(B) and is moved in the circumferential direction (the rotation direction of the arrow shown in Fig. 1(B)) at a speed synchronized with the turntable 20.

[0022] On the turntable 20, as shown in Fig. 1(B), a number of side seal devices (side seal bars) 7 for forming width seals are arranged concentrically. The side seal device 7 that rotates and moves at a speed synchronized with the turntable 20 performs predetermined positioning (circumferential and height direction positioning) on the packaging film F2 that is introduced into the turntable 20 and rotated and moved in the circumferential direction, and at the same time, applies a heat seal in the width direction of the packaging film F2 and locally thermocompresses it.

[0023] At this time, the packaging film at the portion sandwiched by the side seal device 7 melts due to the heat supplied from the side seal device 7. At the same time, since the side seal device 7 sandwiches the packaging film F2, the melted portion of the two-folded packaging film F2 is pressurized. As a result, the heat seal films of the two-folded packaging film F2 are pressure-bonded to form a side seal L2 (see Fig. 2(A), etc.). In this way, a plurality of bag portions with upper openings sandwiched by the side seal device 7 are formed in the two-folded packaging film F2.

[0024] Incidentally, a filling chute 8 is inserted between the two-folded packaging films F2 in parallel with the heat seal operation by the side seal device 7, and the contents measured by the measuring device 10 are introduced via the filling chute 8. The plurality of filling chutes 8 arranged concentrically with the turntable 20 are configured to rotate and move in the circumferential direction (the rotation direction of the arrow shown in Fig. 1(B)) at a speed synchronized with the turntable 20 and thus the packaging film F2.

[0025] After that, the packaging film F3 filled with the contents is sent out from the turntable 20 in the tangential direction (left horizontal direction in Fig. 1(B)), and the top seal device (top seal roll) 11 applies a heat seal to the filling opening (upper opening) of the bag portion of the packaging film F3 and thermocompresses it to form a top seal. As a result, the upper opening packaging film (continuous packaging bag) F3 filled with the contents becomes a continuous packaging bag F4 with the contents sealed (see Fig. 1(A), (B)).

[0026] Subsequently, the sewing machine device 15 and the cutter device 16 form stitches near the center of the side seal L2 and cut the packaging bags at predetermined intervals, producing connected packaging bags P1, P2 (Fig. 1(A)) in which a plurality of packaging bags are connected.

[0027] Fig. 2(A) is a view showing the continuous packaging bag F4 according to the present invention in the plane of Fig. 1(A). In the present embodiment, a sewing machine device 15 for forming stitches in the side seal L2 of the continuous packaging bag F4 is provided. The continuous packaging bag F4 has a plurality of packaging bags connected at a predetermined dimension (pitch) L. In each figure, reference sign F5 indicates the continuous packaging bag that is gripped and conveyed by the clamp conveying device 14, and reference sign F6 indicates the continuous packaging bag with stitches applied. As shown in Fig. 1(B) and enlarged in Fig. 2(B), the sewing machine device 15 is configured to form stitches by sandwiching the side seal L2 of the continuous packaging bag F4 (F5) from both the front and back sides by a sewing cutter 15A that is rotationally driven by a servo motor or the like and a cutter receiving portion 15B. On the outer periphery of the sewing cutter 15A, a cutter portion is formed at a predetermined interval for forming stitches, and a retracted portion that retracts from the receiving portion 15B and does not cut the side seal L2 is formed.

[0028] Here, in the present embodiment, as shown in Figs. 2(B) and (C), the sewing cutter 15A and the cutter receiving portion 15B sandwich the side seal L2 of the continuous packaging bag F4 (F5) from both the front and back sides to form stitches. However, when forming stitches, if the continuous packaging bag F4 (F5) is not properly taut (not pulled with a predetermined tension) in the left-right direction (the conveying direction of the continuous packaging bag) as shown in Fig. 2(C), there may be problems such as the stitches becoming oblique or the stitches not being formed properly. In particular, such problems become prominent when the conveying speed is increased due to the demand for improving the production capacity of the automatic filling and packaging machine.

[0029] The same applies to the cutting device 16. As shown in FIG. 1(B) and enlarged in FIG. 2(B), the cutting device 16 is configured to cut each of the connected packaging bags (P1, P2) connected in a predetermined number by sandwiching the side seal L2 of the continuous packaging bag F4 (F5) from both the front and back sides by a cutter 16A and a cutter receiving portion 16B that are rotationally driven by a servo motor or the like. Note that the outer periphery of the cutter 16A is configured to function as a cutter.

[0030] Therefore, in the present embodiment, it is configured to include a clamp conveying device 14 that can apply tension while linearly conveying the continuous packaging bag F4 (F5). As shown in FIGS. 1(A) and 1(B), the clamp conveying device 14 includes an endless (non-terminating) chain (or belt, etc.) 141 that is an endless (non-terminating) continuous body having a linear portion that moves in a direction coinciding with the linear conveying direction of the continuous packaging bag F4 (F5). Such a chain (or belt, etc.) 141 is looped around a sprocket (or pulley, etc.) (not shown) and is arranged to have the linear portion and an arc portion in a horizontal plane (in the plane of FIG. 1(B)), and is rotationally driven by an electric motor or the like.

[0031] Clamps 142 (143, 144, 145) are attached to the chain 141 at a predetermined interval (pitch) L1. That is, the clamps 142 are arranged in an endless manner at an interval (L1) slightly longer than the product length (L) of each bag of the continuous packaging bag F4 (F5). The clamp 142 has a structure such as that of a laundry clip, and is normally biased to a closed state in which the tip (the lower end in FIG. 2(B)) is closed via a spring (not shown) or the like, while having a configuration that can be set to an open state in which the tip is opened against the biasing force of the spring, and is configured to be able to grip the top seal portion of the continuous packaging bag F4 (F5) in the closed state and release it in the open state. Note that, the clamp in the closed state is denoted by reference numeral 142, the clamp in the open state is denoted by reference numeral 143, the clamp in the state of clamping the top seal portion of the continuous packaging bag F4 (F5) (closed state) is denoted by reference numeral 144, and the clamp in the state of releasing the continuous packaging bag F4 (F5, F6) (open state) is denoted by reference numeral 145.

[0032] Then, as shown in FIG. 1(B), the clamp 142 that is rotationally moved in the direction of arrow B along the arc shape on the outer periphery of a sprocket or the like is moved toward the downstream side of arrow B, and, for example, via a cam mechanism (or pressing mechanism) not shown in the drawings, the interval between the proximal end side of the clamp 142 (the upper end side of reference numeral 144 in FIGS. 2(C) and 3(C)) is narrowed against the biasing force of a spring, whereby the clamp 143 is in an open state with its tip opened. Thereafter, the clamp 143 is further moved in the direction of arrow B, and after being aligned with the conveyance direction of the continuous packaging bag F4 (F5) (the straight portion of the chain 141), at the position of reference numeral 144 in FIG. 1(B), the proximal end side of the clamp 142 is released and the tip of the clamp is closed to grip (or pinch) the top seal portion of the continuous packaging bag F4 (F5), and the continuous packaging bag F4 (F5) is conveyed in the downstream direction.

[0033] Note that, the first clamp 144 (reference numeral 144 at the left end in FIG. 2(C)) grips the corresponding top seal portion of the continuous packaging bag F4 (F5), and the continuous packaging bag F4 (F5) is pulled with respect to the top seal device 12 to apply tension (stretch it). Thereafter, in sequence, while applying tension to the previously clamped clamp 144, tension is similarly applied up to the last clamp 144 (reference numeral 144 at the right end in FIG. 2(C)). In order to make perforations, the attachment pitch of the clamp 144 to the chain 141 is set to L1 (>L), and the drive motor of the chain 141 is controlled such that each clamp 144 moves at a speed that is L1 / L times faster than the conveyance speed of the continuous packaging bag F4 (F5).

[0034] Therefore, in the present embodiment, as shown in FIG. 2(B), with respect to the distance L3 from the upstream end in the product conveyance direction of the side seal L2 to the side seal center C1, the distance L4 from the upstream end in the product conveyance direction of the side seal L2 to the perforation C2 is shorter by L5, that is, in a state where a tension T is applied by pulling a predetermined continuous packaging bag F4 (F5), the perforation is configured to be made.

[0035] According to such a way of making the perforation, as shown in FIG. 2(C), when the perforation position of the first package is aligned in the middle (when the perforation position C2 of the first package is made to coincide with the side seal center C1 and L3 (= L41) = 10 mm), the perforation in the right adjacent position in the figure is shifted 0.4 mm to the right (L42 = 9.6 mm), the perforation in the right adjacent position to that is shifted 0.8 mm to the right (L43 = 9.2 mm), the perforation in the right adjacent position to that is further shifted 1.2 mm to the right (L44 = 8.8 mm), the perforation in the right adjacent position to that is further shifted 1.6 mm to the right (L45 = 8.4 mm), and the cut position in the right adjacent position to that is shifted 2.0 mm to the right (L46 = 8.0 mm). For L41, L42, L43, L44, L45, L46, refer to FIG. 2(C).

[0036] That is, for example, in the case of a six-pack as shown in FIG. 2(C), as it progresses to the right side in the figure, the position of the perforation gradually accumulates and is greatly shifted, and the cut position of the sixth package is shifted by 2 mm. If the width of the side seal L2 is 20 mm, the right side of the cut line is 12 mm and the left side is 8 mm, which is greatly different between the left and right, resulting in a situation where the product quality and appearance are not favorable. Note that the numerical values used in the description here are examples, and the numerical values are according to the conveyance speed of the packaging bag and the clamp, the connection pitch of the connected packaging bags (products), the attachment pitch of the clamp, and the like.

[0037] Note that, as shown in Fig. 1(A), the connected packaging bags (products) P1, P2 cut by the cutting device 16 for each of a plurality of packaging bags are carried out via the first carry-out sliding table 17 and the second carry-out sliding table 18 respectively, and are, for example, boxed. However, it is also possible to have only one carry-out sliding table and only the connected packaging bag (product) P1 (or P2).

[0038] Here, in the present embodiment, in order to suppress the increase in the amount of deviation of the perforation position and the cutting position as the number of the above-mentioned connected packages increases, the control device (operation panel) 19 performs the following control.

[0039] In the present embodiment, in the horizontal rotary type automatic filling and packaging machine 1, when applying a perforation to the side seal L2 between each packaging bag while gripping and conveying the continuous packaging bag F4 (F5’) while applying a predetermined tension by the clamp conveying device 14 (while stretching the continuous packaging bag F4 (F5’) by a predetermined amount), the perforation is applied by the perforation device 15 at a timing earlier than normal by the “cutting position correction value” preset for each packaging bag (L6), and within the same continuous packaging bag F4, the perforation is applied at a timing earlier by the amount obtained by accumulating and adding the correction value for each bag one by one. At the end of one set, cutting is performed at the position corrected by the same cumulative correction, and after cutting, the timing is delayed by the accumulated amount to reset the correction (see Fig. 4(A), (B), etc.).

[0040] Note that the perforation cutter 15A and the cutter receiving part 15B constituting the perforation device 15 are rotationally driven by a servo motor or the like. Since the rotational drive control is independent of the conveyance of the continuous packaging bag F4 and other devices, by controlling the servo motor, it is possible to independently control (change the setting) the adjustment of the perforation position (the timing of making the perforation) appropriately from others.

[0041] Similarly, for the cutting device 15, the cutter 16A and the cutter receiving part 16B are rotationally driven by a servo motor or the like, and the rotational drive control is independent of the conveyance of the continuous packaging bag F4 and other devices. Therefore, by controlling the servo motor, it is possible to independently control (change the setting) the adjustment of the cutting position (cutting timing) as appropriate from others.

[0042] The stitch position correction control and the cut position correction control will be described according to FIG. 4(B). Note that the control is performed by the control device 19. In step 1 (denoted as S in the figure; the same applies hereinafter), as shown in FIG. 4(A), the cut position correction amount (stitch position correction amount) is input to the control device (operation panel) 19. Here, 0.4 mm is input. The stitch position correction amount or the cut position correction amount is a correction amount (correction value) with respect to the reference value of the stitch position or the cut position of each packaging bag (here, the first to sixth packages) determined from the inter-bag pitch L of the continuous packaging bag F4 in FIG. 2(A) and the arrangement pitch L1 of the clamps in FIG. 2(C), etc. (in other words, the value set without considering the elongation when the continuous packaging bag F4 (F5’) is tensioned to a predetermined value and stitched or cut). In step 2, the number of connected stitches is input. Here, the connection number 6 is input. In step 3, the operation of the packaging machine 1 is started. In step 4, for the first package: advance the stitch position (L41→L71: refer to FIG. 3(C); the same applies hereinafter) by 0.4 mm (correction cumulative value -0.4 mm). That is, the control device 19 controls the drive of the stitching device 15 so that the timing of inserting the stitches of the first package is advanced by 0.4 mm (correction cumulative value -0.4 mm) with respect to the reference value of the first package. In step 5, for the second package: advance the stitch position (L72) by 0.4 mm (correction cumulative value -0.8 mm). That is, the control device 19 corrects and controls the drive of the stitching device 15 so that the timing of inserting the stitches of the second package is advanced by 0.4 mm (correction cumulative value -0.8 mm) with respect to the reference value of the second package. In step 6, for the third pack: Advance the stitch position (L73) by 0.4 mm (cumulative correction -1.2 mm). That is, the control device 19 corrects the timing of inserting the stitch of the third pack to be 0.4 mm (cumulative correction -1.2 mm) earlier than the reference value of the third pack and controls the drive of the stitching device 15. In step 7, for the fourth pack: Advance the stitch position (L74) by 0.4 mm (cumulative correction -1.6 mm). That is, the control device 19 corrects the timing of inserting the stitch of the fourth pack to be 0.4 mm (cumulative correction -1.6 mm) earlier than the reference value of the fourth pack and controls the drive of the stitching device 15. In step 8, for the fifth pack: Advance the stitch position (L75) by 0.4 mm (cumulative correction -2.0 mm). That is, the control device 19 corrects the timing of inserting the stitch of the fifth pack to be 0.4 mm (cumulative correction -2.0 mm) earlier than the reference value of the fifth pack and controls the drive of the stitching device 15. In step 9, for the sixth pack: Advance the cut position (L76) by 0.4 mm (cumulative correction -2.4 mm). That is, the control device 19 corrects the timing to be 0.4 mm (cumulative correction -2.4 mm) earlier than the reference value for cutting the side seal L2 of the sixth pack and controls the drive of the cutting device 16. In step 10, reset the correction (cumulative correction 0 mm), return to step 4, and perform the stitching and cutting of the next continuous packaging bag F4.

[0043] After the product P1 (or P2) is produced by cutting with the cutting device 16, for example, via a cam mechanism (or pressing mechanism) not shown in the figure, the interval between the proximal ends of the clamp 144 (the upper end side of the reference numeral 144 in FIGS. 2(C) and 3(C)) is narrowed against the biasing force of the spring to form the clamp 145 in an open state with the tip open, and the continuous packaging bag F4 (F6’) is released as the product P1 (or P2) (see FIG. 1(A)). Thereafter, the clamp 145 releases its proximal end side and the tip of the clamp is made into the closed clamp 142, and it is circulated by the chain 141 again to sandwich the top seal portion of the continuous packaging bag F4 (F5’).

[0044] In this way, since the correction of the stitch position and the cut position can be performed according to the number of connections of the connected packaging bag P1 (or P2), it is possible to keep the stitch position and the cut position constant for each package of the packaging bag while maintaining the cut quality of the product. Therefore, it is possible to manufacture (produce) high-quality connected packaging bags.

[0045] In this embodiment, as the stitch device 15 and the cutting device 16, the case where the cutter is rotated to make stitches or cuts has been described as an example. However, the present invention is not limited to this. For example, a device that presses the cutter to make stitches or slides the cutter to make cuts can be employed.

[0046] Further, in this embodiment, the case where both the stitch device 15 and the cutting device 16 are provided has been exemplified. However, the present invention is not limited to this, and a configuration including only the cutting device 16 can also be adopted.

[0047] It should be noted that various modifications can be made without departing from the gist of the present invention.
