Description

[Technical field]

[0001] The present invention relates to the adjustment of various adjustment devices in packaging-related apparatus such as pillow packaging machines, wrapping packaging machines, overwrap packaging machines, and boxing machines. [Background technology]

[0002] Packaging-related equipment includes pillow packaging machines, which sequentially fill cylindrically formed packaging material with packaged products and then seal and cut the product to produce a package; wrapping packaging machines, which package the products by wrapping them in cut packaging material; overwrap packaging machines, which cover one or more packaged products with packaging material; and boxing devices, which box products. Pillow packaging machines include vertical pillow packaging machines, which feed the packaging material up and down (vertically) to fill it with packaged products, and horizontal pillow packaging machines, which feed the packaging material left and right (horizontally) to fill it with packaged products. In such packaging-related equipment, when switching between products to be produced, it is necessary to carry out setting and adjustment work to align the positions of various adjustment devices with the installation values ​​for the product to be produced next. For example, the setting and adjustment of the various adjustment devices on a vertical pillow packaging machine includes setting and adjusting the left and right position of the rolled packaging material, setting and adjusting the date printing feed direction position and left and right position of the date printing, setting and adjusting the position of the slide roller in front of the tube maker, setting and adjusting the position of the vertical sealing block, and setting and adjusting the packaging material cutting position, while on a horizontal pillow packaging machine, setting and adjusting the angle and distance of the tension roller. Each adjustment device is provided with a scale or the like that indicates its position, and an operator manually sets and adjusts the position of each adjustment device. This means that the setup and adjustment of various adjustment devices takes a lot of time, placing a heavy workload on workers and reducing production efficiency, and so improvements in this area were needed.

[0003] In this regard, Patent Document 1 (JP 2019-34772 A) discloses a product processing device that is an apparatus for packaging or boxing products, and is equipped with a memory unit that stores settings related to the packaging or boxing of the products, and a display unit that displays adjustment parts that need to be adjusted in the apparatus and their setting values ​​when the settings are changed.A bag-making packaging machine is cited as an example of the product processing device, and examples of adjustment parts include the position of the former roller, the left and right printing positions, the top and bottom printing positions, and the film position sensor position. However, the product processing device of Patent Document 1 merely displays the setting values ​​of the parts requiring adjustment on the display unit, and the adjustment of the parts requiring adjustment must itself be performed by the operator, which still imposes a heavy workload on the operator and does not significantly improve the decline in production efficiency. In particular, in tasks that require manual adjustment of the position of adjustment equipment (tension rollers), such as adjusting the angle and distance of the tension rollers on a horizontal pillow packaging machine, there is little improvement in the workload of the worker or the decline in production efficiency.

[0004] In addition, Patent Document 2 (JP 2019-85152 A) discloses a vertical form-fill-seal packaging machine in which a control device controls the operation of the vertical sealing device, horizontal sealing device, and packaging material feed device to produce a bag package containing a product by applying a vertical seal to a strip of packaging material to form a tubular packaging material, and then applying a horizontal seal to the tubular packaging material to produce a bag package containing a product.The control device adjusts at least one of the support position of the packaging material roll in the packaging material roll support device, the approach / retraction position of the strip of packaging material guiding device relative to the former, the approach / retraction position of the vertical sealing device relative to the filling tube, and the approach / retraction position of the packaging material feed device relative to the filling tube to a position corresponding to the strip width or fold diameter of the strip of packaging material in response to setting information regarding the strip width or fold diameter of the strip of packaging material obtained based on setting input to the control device. However, in the vertical form-fill-seal packaging machine of Patent Document 2, the control device adjusts at least one of the positions of the support position of the packaging material roll, the approach / retraction position of the strip-shaped packaging material guiding device relative to the former, the approach / retraction position of the vertical sealing device relative to the filling tube, and the approach / retraction position of the packaging material feed device relative to the filling tube, eliminating the need for manual adjustment by an operator. However, because new drive equipment is installed to adjust each adjustment device and the control device controls each newly installed drive equipment, the vertical form-fill-seal packaging machine is equipped with excessive automated equipment, making the machine expensive and creating another problem in that excessive strain is placed on the maintenance and upkeep of each adjustment device.

As shown in the figure, the former tension unit 30 is composed of a tension roller 31, tension arms 32, 33, an arm support shaft 34, an arm fixing unit 35, pinions 36a, 36b, racks 36c, 36d, a roller fixing unit 37, and the like. The tension roller 31 is rotatably held by roller shafts 31a and 31b, and pinions 36a and 36b are attached to the roller shafts 31a and 31b. The tension arms 32, 33 are supported by an arm support shaft 34, and the rear end of the arm support shaft 34 is rotatably held by a rear frame (not shown) of the horizontal pillow packaging machine main body 2. The tension arms 32, 33 are provided with grooves 32m, 33m in the longitudinal direction, and racks 36c, 36d are attached to the opposing surfaces of the tension arms 32, 33 along the grooves 32m, 33m. The arm fixing portion 35 is composed of a clamping block 35a consisting of an upper block 35a1 and a lower block 35a2, and a fixed lever portion 35b consisting of a cylindrical portion 35b1, a lever 35b2, and a threaded rod 35b3, and the end of the upper block 35a1 is fixed to the rear frame (not shown) of the horizontal pillow packaging machine main body 2. The roller fixing portion 37 is made up of a knob 37a, a fixed lever portion 37b consisting of a cylindrical portion 37b1, a lever 37b2 and a threaded rod 37b3, a pressing plate 37c and a slide block 37d.

[0023] In the arm fixing portion 35, the end 34a of the arm support shaft 34 protruding from the tension arm 32 is fitted into a clamping hole 35a3 formed by the upper block 35a1 and the lower block 35a2, and the screw rod 35b3 of the fixed lever portion 35b passes through the hole 35a4 on the upper block 35a1 side and is screwed into the hole 35a4 on the lower block 35a2 side. By rotating the lever 37b2 clockwise, the cylindrical portion 35b1 presses the lower block 35a2 via the upper block 35a1, whereby the inner surface of the clamping hole 35a3 presses the end 34a of the arm support shaft 34, preventing the tension arms 32, 33 from rotating and fixing the angle of the tension arms 32, 33. The tension roller 31 is attached to the tension arms 32, 33 with the roller shafts 31a, 31b fitted in grooves 32m, 33m of the tension arms 32, 33 and the pinions 36a, 36b meshing with the racks 36c, 36d. In the roller fixing portion 37, the roller shaft 31a of the tension roller 31 passes through hole 37c1 of the pressing plate 37c and is fixed to the knob 37a. As a result, when the knob 37a is rotated to rotate the roller shaft 31a, the pinion 36a rotates and moves on the rack 36c, and in conjunction with this, the pinion 36b also rotates and moves on the rack 36d, and the tension roller 31 moves along the grooves 32m, 33m of the tension arms 32, 33. On the other hand, the convex portion of the slide block 37d of the roller fixing portion 37 is fitted into the groove 32m of the tension arm 32, and the screw rod 37b3 of the fixed lever portion 37b passes through the hole 37c2 of the movable plate 37c and is screwed into the screw hole 37d1 of the slide block 37d, so that the roller fixing portion 37 (fixed lever portion 37b, movable plate 37c, slide block 37d) moves together with the movement of the tension roller 31 due to the rotation of the knob 37a. Then, by rotating lever 37b2 clockwise, the cylindrical portion 37b1 presses the movable plate 37c against the front side of the tension arm 32, and the slide block 37d presses the back side of the tension arm 32, thereby immobilizing the movable plate 37c and the tension roller 31, and fixing the position of the tension roller 31 on the tension arms 32, 33.

[0024] Here, the position adjustment of the tension roller 31 will be described. In the horizontal pillow packaging machine 1, the size (width, height) of the opening of the former 41 can be changed according to the size of the packaged product CP. Therefore, it is necessary to change the position of the tension roller 31 in accordance with the size of the opening of the former 41 so that the guide angle of the packaging material Fi guided to the former 41 is constant. In addition, it is also necessary to adjust the path length of the packaging material Fi from the position of the registration mark (register mark) of the packaging material Fi detected by the registration mark detector provided in the packaging material supply / feed section 10 to the end seal / cutting position so that it is an integer multiple of the length of the package Pc. For this reason, the position of the tension roller 31 can be changed, and the position of the tension roller 31 is set for each product produced by the horizontal pillow packaging machine 1, and position adjustment is performed to move the tension roller 31 to that set position. The position of the tension roller 31 is determined by the angle (tension arm angle) of the tension arm 32 (33) relative to the horizontal plane and the distance (tension roller distance) from a reference position on the tension arm 32 (33) to the tension roller 31. Therefore, to adjust the position of the tension roller 31, the angle is adjusted by rotating the tension arm 32 (33) around the arm support shaft 34 so that the tension arm angle becomes the set value, and the distance from the reference position is adjusted by turning the knob 37a to move the tension roller 31 so that the tension roller distance becomes the set value.

[0025] [Rotary encoder, linear encoder] The tip of the end 34a of the arm support shaft 34 protrudes from a clamping hole 35a3 of the clamping block 35a, and a rotary encoder 38 is attached to the tip of the protruding end 34a by fitting into a shaft hole 38a. A linear encoder 39 is attached to the front side of the tension arm 32 in the longitudinal direction along the groove 32m, and a sensor head 39a is connected to the moving plate 37c. FIG. 5 is a front view of tension arm 32 to explain the tension arm angle detected by rotary encoder 38 and the tension roller distance detected by linear encoder 39. In the figure, Cp is the center point of end 34a, Hp is the reference plane (horizontal plane), and Rp is the position (reference position) where tension roller 31 has moved to the tip-most side of tension arm 32. The rotary encoder 38 detects the angular displacement θ of the tension arm 32 from the reference plane Hp when the tension arm 32 rotates around the center point Cp, and outputs the detected angular displacement θ as the tension arm angle θ of the tension arm 32 with respect to the reference plane Hp. When the tension roller 31 moves along the groove 32m of the tension arm 32, the linear encoder 39 detects the distance L from the position (reference position) Rp to the tension roller 31, and outputs it as the tension roller distance L. The position of the tension roller 31 in the horizontal pillow packaging machine body 2 is detected based on the tension arm angle θ output by the rotary encoder 38 and the tension roller distance L output by the linear encoder 39.

[0030] The buzzer 61 serves as a sound generator of the present invention, and emits intermittent sounds with different intermittent periods. This buzzer 61 is attached to the outside of the outer frame 60 next to the auxiliary operation panel 70 near the former tension section 30 (see Figure 1), so that the intermittent sound of the buzzer 61 can be easily heard by an operator adjusting the position of the tension roller 31. The indicator lamp 62 is a light-emitting device of the present invention, and flashes at different intervals. This indicator light 62 is attached to the outside of the outer frame 60 next to the buzzer 61 near the former tension section 30 (see Figure 1), so that the worker adjusting the position of the tension roller 31 can easily see the flashing indicator light 62. Incidentally, instead of the indicator lamp 62, the input display section 84 of the auxiliary operation panel 80 may be provided with a flashing light emitting function to serve as the light emitting device of the present invention.

[0031] [Adjustment status information generation unit] As described above, in the horizontal pillow packaging machine control unit 90, the adjustment state information generating unit 91b of the arithmetic control unit 91 includes a tension arm angle information generating unit 91b1 and a tension roller distance information generating unit 91b2. When an operator adjusts the position of the tension roller 31, the tension arm angle information generating unit 91b1 compares the tension arm angle θ detected by the rotary encoder 38 and sent to the horizontal pillow packaging machine control unit 90 with the tension arm angle θs stored in the product parameter table of the memory unit 92. If θ changes to approach θs, it generates adjustment possible information (data) indicating that adjustment is possible, such as "01", if θ changes to move away from θs, it generates non-adjustable information (data) indicating that adjustment is not possible, such as "00", and if the difference between θ and θs falls within the allowable range, it generates adjustment completed information (data) such as "11". In addition, when the operator adjusts the position of the tension roller 31, the tension roller distance information generation unit 91b2 compares the tension roller distance L detected by the linear encoder 39 and sent to the horizontal pillow packaging machine control unit 90 with the tension roller distance Ls stored in the product parameter table of the memory unit 92, and if L changes to approach Ls, generates adjustment possible information (data) indicating that adjustment is possible, such as "01", if L changes to move away from Ls, generates non-adjustable information (data) indicating that adjustment is not possible, such as "00", and if the difference between L and Ls falls within the allowable range, generates adjustment completed information (data) such as "11".

[0032] The adjustment possible information (data) "01", the adjustment impossible information (data) "00", and the adjustment completed information (data) "11" generated by the adjustment status information generator 91b (tension arm angle information generator 91b1 and tension roller distance information generator 91b2) are sent to the buzzer 61 and the indicator light 62. When adjustment possible information (data) "01" is sent from the calculation control unit 91 (adjustment status information generating unit 91b), the buzzer 61 emits intermittent sound A, when adjustment impossible information (data) "00" is sent, the buzzer emits intermittent sound B having a different intermittent period than intermittent sound A (for example, a longer intermittent period), and when adjustment completion information (data) "11" is sent, the intermittent sound A stops. The indicator light 62 blinks with a period T1 when adjustment possible information (data) "01" is sent from the calculation control unit 91 (adjustment status information generating unit 91b), blinks with a period T0 different from the period T1 (for example, T0 is greater than T1) when adjustment impossible information (data) "00" is sent, and stops blinking when adjustment completion information (data) "11" is sent. Furthermore, the indicator lamp 62 may be configured to light up different colors instead of blinking based on the adjustment possible information (data) and the like sent from the calculation control unit 91. For example, the indicator lamp 62 may be configured to light up blue when the adjustment possible information (data) "01" is sent, light up yellow when the adjustment impossible information (data) "00" is sent, and light up green when the adjustment complete information (data) "11" is sent. Furthermore, if the input display unit 84 of the auxiliary operation panel 80 is given a flashing light function instead of the indicator light 62, the adjustment possible information (data) "01", the adjustment impossible information (data) "00", and the adjustment completed information (data) "11" generated by the adjustment status information generating unit 91b are sent to the auxiliary operation panel 80 via the communication line CL2, and the indication mark displayed on the input display unit 84 flashes or stops flashing (details will be described later). Although the horizontal pillow packaging machine 1 is provided with both the buzzer 61 and the indicator light 62, it may be provided with only one of them.

[0033] [Operation of horizontal pillow packaging machine 1 during tension roller position adjustment work] Figures 7 and 8 are flowcharts showing the operation of the horizontal pillow packaging machine 1 during the tension roller position adjustment work, Figure 9 is an explanatory diagram explaining the movement of the tension arm 32 and the tension roller 31, and Figure 10 is a screen configuration diagram of the screen displayed on the input display unit 84 of the auxiliary operation panel 80. The operation of the horizontal pillow packaging machine 1 will be described below with reference to the drawings. Now, as shown in Figure 9(a), assume that the tension arm 32 is at a position with a tension arm angle θ (= 40 degrees), the tension roller 31 is at a position with a tension roller distance L (= 90 mm), and the tension arm angle θs (= 20 degrees) and tension roller distance Ls (= 150 mm) are set (stored) in the product parameter table of the memory unit 92. In Figure 9(a), P1 is the current position of the tension roller 31, Ps is the set position of the tension roller 31, and the tension arm 32 and tension roller 31 in the current position are represented by solid lines, and the tension arm 32 and tension roller 31 in the set position are represented by dotted lines. First, by operation of the operator, the tension arm angle θs (= 20 degrees) and tension roller distance Ls (= 150 mm) stored in the product parameter table in the memory unit 92 of the horizontal pillow packaging machine control unit 90 are displayed on the input display unit 84 of the auxiliary operation panel 80 (S1). FIG. 10(a) shows a screen displayed on the input display section 84 of the auxiliary operation panel 80 in step S1. In the figure, 110 is a memo screen, BX1 to BX4 are display boxes, and M1 and M2 are instruction marks. On the memo screen 110, the words "Memo screen", "Item name", "Setting value", "Current position", "Tension arm angle", and "Tension roller distance" are displayed in the positions shown in the figure. In this memo screen 110, display box BX1 displays the number "20" indicating the set tension arm angle θs (= 20 degrees), display box BX2 displays the number "150" indicating the set tension roller distance Ls (= 150 mm), display box BX3 displays the number "40" indicating the current angle θ (= 40 degrees) of the tension arm 32, and display box BX4 displays the number "90" indicating the current distance L (= 90 mm) of the tension roller 31, with an indication mark M1 to the right of the number "40" indicating that the current angle θ (= 40 degrees) of the tension arm 32 is greater than the set value θs (= 20 degrees), and an indication mark M2 to the right of the number "90" indicating that the current distance L (= 90 mm) of the tension roller 31 is less than the set value Ls (= 150 mm). If the input display section 84 of the auxiliary operation panel 80 is provided with a flashing light emitting function instead of the indicator lamp 62, the instruction marks M1 and M2 displayed on the memo screen 110 will flash.

[0034] Here, when the worker begins adjusting the tension arm angle and the tension arm 32 (33) rotates around the arm support shaft 34 (center point Cp), the rotary encoder 38 detects the tension arm angle θ (S2), the detected angle θ is sent to the calculation control unit 91 of the horizontal pillow packaging machine control unit 90, and the tension arm angle information generation unit 91b1 determines whether the angle θ is changing to approach the set angle θs (=20 degrees) (S3). Then, when the tension arm angle information generating unit 91b1 determines that the angle θ is changing to approach the set angle θs (=20 degrees), it generates and outputs adjustment possible information (data) "01" indicating that adjustment is possible (S4). This adjustment possible information (data) "01" is sent to the buzzer 61 and the indicator light 62, the buzzer 61 emits an intermittent sound A and the indicator light 62 flashes with a period T1 (S5), notifying the operator that the direction in which to rotate the tension arm 32 (33) is correct. Next, the tension arm angle information generator 91b1 determines whether the difference between the angle θ detected by the rotary encoder 38 and the set angle θs (=20 degrees) is within an acceptable range, for example, within 5% (19 to 21 degrees) of θs (=20 degrees) (S6), and if it determines that it is not within the acceptable range, the process returns to step S5, the buzzer 61 emits an intermittent sound A, and the indicator light 62 continues to flash with a period T1. Then, when the tension arm angle information generating unit 91b1 determines that the difference between the angle θ detected by the rotary encoder 38 and the set angle θs (=20 degrees) is within the allowable range, it generates and outputs adjustment completion information (data) "11" (S7). This adjustment completion information (data) "11" is sent to the buzzer 61 and the indicator light 62, the buzzer 61 stops the intermittent sound A and the indicator light 62 stops flashing (S8), notifying the operator that the adjustment of the tension arm angle is complete.

[0035] FIG. 9(b) shows the state in step S7 above, that is, the state in which the tension arm 32 (33) has rotated around the arm support shaft 34 (center point Cp) and the tension arm angle has become the set value θs (=20 degrees). In the figure, P2 is the position of the tension roller 31, and the tension arm 32 in the position before it rotates is represented by a dotted line, the tension roller 31 is represented by a dashed line, and the tension arm 32 and tension roller 31 in the position after the tension arm 32 has rotated to a tension arm angle θs (=20 degrees) are represented by solid lines. As shown in FIG. 9(b), the tension arm 32 rotates in the direction of the arrow Y1, the tension roller 31 moves from position P1 to position P2, the tension arm angle becomes θs (=20 degrees), and the tension roller distance becomes L (=90 mm). FIG. 10(b) shows a memo screen 110 displayed on the input display section 84 of the auxiliary operation panel 80 in the state of step S7. On the memo screen 110, the display box BX3 showing the current position (angle) of the tension arm 32 displays the number "20" indicating the adjusted tension arm angle θs (=20 degrees), and to the right of that is an indication mark M0 indicating that the angle adjustment of the tension arm 32 has been completed.

[0036] On the other hand, in step S3 above, if the tension arm angle information generating unit 91b1 determines that the angle θ detected by the rotary encoder 38 has not changed to approach the set angle θs (=20 degrees), in other words, that θ has changed to move away from θs, it generates and outputs non-adjustment information (data) "00" (S9). This adjustment impossible information (data) "00" is sent to the buzzer 61 and the indicator light 62, and the buzzer 61 emits an intermittent sound B with a longer intermittent period than the intermittent sound A, and the indicator light 62 flashes with a period T0 longer than the period T1 (S10), notifying the operator that the direction in which the tension arm 32 (33) is being rotated is incorrect. Then, the process returns to step S2, and detection of the tension arm angle θ by the rotary encoder 38 continues.

[0037] Next, when the worker finishes adjusting the tension arm angle and starts adjusting the tension roller distance, and the knob 37a is turned to move the tension roller 31, the linear encoder 39 detects the tension roller distance L (S11), and the detected distance L is sent to the calculation control unit 91 of the horizontal pillow packaging machine control unit 90, and the tension roller distance information generation unit 91b2 determines whether the distance L is changing to approach the set distance Ls (=150 mm) (S12). Then, when the tension roller distance information generating unit 91b2 determines that the distance L is changing to approach the set distance Ls (=150 mm), it generates and outputs the adjustment possible information (data) "01" indicating that adjustment is possible (S13). This adjustment possible information (data) "01" is sent to the buzzer 61 and the indicator light 62, the buzzer 61 emits an intermittent sound A and the indicator light 62 flashes with a period T1 (S14), notifying the operator that the direction in which the tension roller 31 is being moved is correct. Next, the tension roller distance information generation unit 91b2 determines whether the difference between the distance L detected by the linear encoder 39 and the set distance Ls (=150 mm) is within an acceptable range, for example, within 3% (145 to 155 mm) of Ls (=150 mm) (S15), and if it determines that it is not within the acceptable range, the process returns to step S14, the buzzer 61 emits an intermittent sound A, and the indicator light 62 continues to flash with a period T1. Then, when the tension roller distance information generating unit 91b2 determines that the difference between the distance L detected by the linear encoder 39 and the set distance Ls (=150 mm) is within the allowable range, it generates and outputs adjustment completion information (data) "11" (S16). This adjustment completion information (data) "11" is sent to the buzzer 61 and the indicator light 62, the buzzer 61 stops the intermittent sound A, and the indicator light 62 stops flashing (S17), notifying the operator that the adjustment of the tension roller distance is complete.

[0038] FIG. 9(c) shows the state in step S16 above, that is, the state in which the tension roller 31 has moved in the longitudinal direction along the groove 32 of the tension arm 32, and the tension arm distance has become the set value Ls (=150 mm). In the figure, the tension roller 31 is shown by a dashed line when it is at a position P2 before it moves, and the tension roller 31 is shown by a solid line when it has moved to a position Ps. As shown in FIG. 9(c), the tension roller 31 moves in the direction of the arrow Y2 from position P2 to position Ps, and the tension roller distance becomes Ls (=150 mm). FIG. 10(c) shows a memo screen 110 displayed on the input display section 84 of the auxiliary operation panel 80 in the state of step S16. On the memo screen 110, the display box BX4 showing the current position (distance) of the tension roller 31 displays the number "150", indicating that the tension roller distance after adjustment is Ls (=150 mm), and to the right of this is an indication mark M0, indicating that the distance adjustment of the tension roller 31 is complete.

[0039] On the other hand, in step S12 above, if the tension roller distance information generating unit 91b2 determines that the distance L detected by the linear encoder 39 has not changed to approach the set distance Ls (=150 mm), that is, L has changed to move away from Ls, it generates and outputs the non-adjustable information (data) "00" (S18). This adjustment impossible information (data) "00" is sent to buzzer 61 and indicator light 62, and buzzer 61 emits intermittent sound B with a longer intermittent period than intermittent sound A, and indicator light 62 flashes with period T0 longer than period T1 (S19), notifying the operator that the direction in which tension roller 31 is being moved is incorrect. Then, the process returns to step S11, and detection of the tension roller distance L by the linear encoder 39 continues. In addition, if the input display unit 84 of the auxiliary operation panel 80 is given a flashing light-emitting function instead of the indicator light 62, in step S5, the indication mark M1 displayed on the memo screen 110 will flash with a cycle T1, in step S10, the flashing of the indication mark M1 will stop and the indication mark M0 will be displayed, in step S10, the indication mark M1 will flash with a cycle T0, in step S14, the indication mark M2 displayed on the memo screen 110 will flash with a cycle T1, in step S17, the flashing of the indication mark M2 will stop and the indication mark M0 will be displayed, and in step S19, the indication mark M2 will flash with a cycle T0.

[0040] As described above, when the worker adjusts the tension arm angle, the rotary encoder 38 detects the tension arm angle θ, and the tension arm angle information generation unit 91b1 determines whether the angle θ is changing to approach the set angle θs, and if the angle θ is changing to approach the set angle θs, the buzzer 61 emits intermittent sound A and the indicator light 62 flashes with a period T1 to inform the worker that the direction in which the tension arm 32 is rotated is correct, and if the angle θ is changing to move away from the set angle θs, the buzzer 61 emits intermittent sound B and the indicator light 62 flashes with a period T0 to inform the worker that the direction in which the tension arm 32 is rotated is incorrect. The tension arm angle information generation unit 91b1 also determines whether the difference between the angle θ and the set angle θs is within an allowable range, and if it is within the allowable range, the buzzer 61 stops intermittent sound A and the indicator light 62 stops flashing, notifying the worker that adjustment of the tension arm angle is complete. Furthermore, when the worker adjusts the tension roller distance, linear encoder 39 detects tension roller distance L, and tension roller distance information generation unit 91b2 determines whether distance L is changing to approach set distance Ls, and if distance L is changing to approach set distance Ls, buzzer 61 emits intermittent sound A and indicator light 62 flashes with a period of T1 to inform the worker that the direction in which tension roller 31 is moved is correct, and if distance L is changing to move away from set distance Ls, buzzer 61 emits intermittent sound B and indicator light 62 flashes with a period of T0 to inform the worker that the direction in which tension roller 31 is moved is incorrect. Furthermore, tension roller distance information generation unit 91b2 determines whether the difference between distance L and set distance Ls is within an allowable range, and if it is within the allowable range, buzzer 61 stops intermittent sound A and indicator light 62 stops flashing, notifying the worker that adjustment of the tension roller distance is complete. Therefore, an operator can efficiently and reliably complete adjustment work of the tension roller position (tension arm angle, tension roller distance) in a horizontal pillow packaging machine in a short period of time.
