Description

  The present invention relates to a packaging apparatus that cuts a packaging sheet into a desired length so as to be used for a packaging operation of an article to be packaged.

  In supermarkets and farmers, packaging apparatuses are used that draw a packaging film from a film roll in which the packaging film is wound into a roll and cut it to a desired length. Examples of the items to be packaged include fresh foods and side dishes. From the viewpoint of providing information to the consumer, the date of manufacture, the name of the manufacturer / producer, etc. are displayed on the product packaged using the packaging film. As a display method, sticking a sticker has already been performed, but in order to reduce costs and improve work efficiency, it is desired to print directly on a packaging film.

  As a configuration for performing such direct printing, it is conceivable to provide a printing apparatus that thermally transfers a thermal transfer material to a packaging film with a thermal head. In an automatic packaging apparatus that performs all packaging operations automatically, a configuration in which such a printing apparatus is provided has been known (see Patent Document 1).

The packaging device according to any one of 1 to 7.

  According to the means 8, it is suppressed by the regulating member that the wound sheet is swayed left and right when the packaging sheet is pulled out. Thereby, the packaging sheet can be pulled out smoothly. Moreover, if the restriction position by the restriction member is changed in the left-right direction, the position where the packaging sheet is pulled out is changed to the left and right. As a result, the relative position between the printing body of the marking means and the packaging sheet is changed in the left-right direction, and the position for marking on the packaging sheet is also changed in that direction. As a result, the versatility of the packaging apparatus provided with the marking means can be enhanced, for example, by appropriately changing the marking position according to the type of the packaging sheet.

  Here, in a printing apparatus using thermal transfer, it is possible to employ a configuration in which a thermal head is moved left and right to perform printing at a desired position. Therefore, when changing the printing position, it is not necessary to move the printing object to the left and right. On the other hand, in the structure provided with the marking means, the marking position cannot be changed unless the position of the printed body itself or the left and right position of the packaging sheet is changed. For this reason, the subject of changing the left and right positions of the printing body or the packaging sheet in order to change the printing position becomes a big problem in the configuration provided with the above-mentioned marking means.

  And it is desirable for the structure for changing the left-right position of a printing body or a packaging sheet to be the structure which can change the position easily. However, when trying to realize it on the printing body side, there arises a problem that the configuration becomes complicated. One of the factors is that the printed body must be supported at a position away from the packaging sheet while avoiding interference with the packaging sheet drawn continuously from the wound sheet.

  Therefore, if the restriction member that restricts the position of the wound sheet as in the means 8 is configured to change the restriction position to the left and right, it is not necessary to consider interference with the drawn out packaging sheet. Can be simplified. In addition, since the configuration is simple, the manufacturing cost is reduced.

  In addition, in the structure which has the means 4 and the means 8 together, the position of both the said printing body holding | maintenance part and the said packaging sheet can be changed into right and left. For this reason, it is possible to expand the adjustment range of the marking position even if the packaging device is small, by changing both positions to the side away from each other.

The regulating member is a pair of clamping members that clamp the sheet roll from both left and right sides, and at least one clamping member abuts the sheet roll and presses the sheet roll, The packaging device according to means 8, characterized in that a pressing member (pressing plate 164) capable of adjusting the pressing amount is provided.

  According to the means 9, the sheet roll is clamped by the pair of clamping members, so that the lateral variation is regulated. And if the pressing amount of a pressing member is adjusted, the ease of rotation at the time of a sheet | seat roll rotating can be adjusted. When pulling out the packaging sheet manually, the force to pull out the packaging sheet from the rolled sheet varies depending on the operator, so if the ease of rotation is adjusted according to the operator, the packaging sheet may be pulled out too much. It is possible to prevent the drawer from becoming difficult. Moreover, even if the contact state between the sheet roll and the clamping member is incomplete, the sheet roll can be securely held by adjusting the pressing amount of the pressing member.

Means 10. A packaging device in which the packaging sheet is pulled out above the device body,

The printed body support member includes support side portions (support side plates 43 and 44) provided on the left and right sides of the packaging sheet as viewed from the front of the apparatus, and a bridge member (crossover plate 45) bridged between the support side portions. The printed body holding portion is fixed to the transfer member so that the printed body holding portion is supported at a position spaced upward from the packaging sheet, and at the same time, the support side portion is subjected to marking. The bridge plate is supported so that the support state is changed from a state (closed state) to a state where the space above the packaging sheet is expanded (open state) from the state (closed state). Packaging equipment.

  According to the means 11, when the support state of the crossover member is changed to a state in which the space above the packaging sheet is widened, the degree of the interference is reduced when the crossover member and the hand interfere with each other. Thereby, it is possible to facilitate the work.

Thus, a recess 75 is formed by the upper plate 21 and the rising plates 73 and 74.

  Thus, the upper plate 21 is disposed at a position lower than the upper end edges of the main body side plates 13 and 14. For this reason, the packaging film 17 drawn out from the film roll 19 and passing under the first and second pressing rollers 52 and 56 has its adhesive portions 17a and 17b as a whole attached to the upper plate 21 as shown in FIG. It does not stick, and is configured to only stick to the upper ends of the rising plates 73 and 74. Thereby, sticking to the upper board 21 of the packaging film 17 is suppressed to the minimum.

  As a second feature, the manual packaging device 11 is configured so that the film pressing device 22 can easily pass the packaging film 17 drawn from the film roll 19. Specifically, it has the following configuration, which will be described with reference to FIGS. 3, 6, and 7. FIG. 6 is a front view of the film pressing device, and FIG. 7 is a front view showing an opened state of the film pressing device.

  As described above, the film pressing device 22 includes the support substrate 41 and the transition plate 45 supported by the left and right support side plates 43 and 44. As shown in FIG. 3, the bridge plate 45 and the left support side plate 43 are connected by a hinge device 81. For this reason, as shown in FIG. 6, the bridge plate 45 is placed on the receiving pieces 43a and 44a and bridges between the left and right support side plates 43 and 44, and a flat portion as shown in FIG. Between the open state where the upper part of 42 is opened, the hinge device 81 can be rotated around the hinge axis.

  A flange 82 is provided at the right end of the transition plate 45, and a lock device 83 that can be engaged with the flange 82 is provided on the right support side plate 44. And the crossing board 45 made into the closed state is fixed by engaging both. When the lock device 83 is released, the engagement with the flange portion 82 is released, and the transition plate 45 can be opened. The left support side plate 43 is provided with a rotation restricting plate 84 outside the hinge device 81. When the transition plate 45 is in the open state, the pivot piece of the hinge device 81 is in contact with the pivot restriction plate 84, so that further pivoting of the transition plate 45 is restricted and the open state is maintained. Is done.

  Next, the operation of the film pressing device 22 configured as described above will be described.

  Before pulling out the packaging film 17 from the film roll 19, the locking device 83 is released, and the transition plate 45 is rotated until the rotation piece of the hinge device 81 comes into contact with the rotation restricting plate 84 to open the transition plate 45. To do. In this open state, the upper side of the flat portion 42 of the support substrate 41 is opened, so that the hand holding the packaging film 17 does not interfere with the cross board 45 and the first and second press rollers 52 and 56, and can be easily The packaging film 17 can be pulled out. After the packaging film 17 is pulled out to the front side of the main body frame 12, the transition plate 45 is rotated in the reverse direction to return to the original closed state, and the state is fixed by the lock device 83.

  Further, not only at the beginning of the packaging operation described above, but also when the work is performed on the packaging film 17 during or at the end of the packaging operation, for example, dealing with a defect of the packaging film 17, the hand interferes with the film pressing device 22. In such a case, if the bridge plate 45 is opened in the same manner as described above, these operations can be easily performed.

  As a third feature, the manual packaging device 11 includes a stamping device 91 as a marking means for marking the packaging film 17. Specifically, it has the following configuration, which will be described with reference to FIGS. 1 to 5, 8, and 9. FIG. 8 is an exploded perspective view of the stamp unit constituting the stamp device, and FIG. 9 is an operation explanatory diagram for explaining the marking operation by the stamp unit.

  As shown in FIGS. 3 and 4, the stamp device 91 includes a stamp unit 92 as a print body holding unit provided in the film pressing device 22, a stamp mat 93, and a print body provided in the stamp unit 92. And the configuration for executing printing by the stamp 94. Note that the stamp 94 in the present embodiment uses ink that can be printed on a non-absorbing surface such as the packaging film 17 and is generally commercially available. Further, since the stamp portion 92 is supported by the support substrate 41 and the bridge plate 45, a print body support member is constituted by both of them.

  The stamp portion 92 includes a support member 96 provided at the central portion in the left-right direction of the flat portion 46 of the crossover plate 45. As shown in FIG. 8, the support member 96 is formed by bending a plate body, and a fixing portion 97 fixed to the flat portion 46 of the transition plate 45, and a base portion bent upward at the front end portion of the fixing portion 97. 98 and a mounting portion 99 that is bent forward at the upper end portion of the base portion 98. The base 98 is provided with a stamp housing member 101 on the front side thereof.

  A guide member 109 formed in a lip groove shape is fixed to the front surface of the base portion 98 by a fixing screw 107. The guide member 109 is disposed such that the lip portion 109a faces forward and the back surface portion 109b contacts the base portion 98. Further, the groove 109c of the guide member 109 is disposed so as to extend in the vertical direction.

  The stamp accommodating member 101 is provided with a back surface portion 102, left and right side surface portions 103 and 104, and an upper surface portion 105 according to the shape of the stamp 94 accommodated in the stamp accommodating member 101.

  An interposition member 106 is fixed to the rear surface of the back surface portion 102 with a fixing screw 107. On the front surface of the interposition member 106, a convex portion 106a protruding forward is formed so as to extend in the vertical direction. Also, guided portions 106b extending in the vertical direction are formed on both the left and right sides. The interposition member 106 is dimensioned so that it can be inserted from the end of the guide member 109 and slid in the vertical direction, and is inserted into the groove 109c of the guide member 109 after being fixed to the stamp housing member 101. Is done.

  A stamp support piece 108 formed by bending the lower end portion inward is provided at the lower ends of the back surface portion 102 and the left and right side surface portions 103 and 104. The stamp support piece 108 supports the lower end of the stamp 94 fitted in the stamp accommodating member 101 from the open side of the front surface, whereby the stamp 94 is held in the state accommodated in the stamp accommodating member 101.

  On the other hand, a through hole 111 is formed in the mounting portion 99 described above.

  The stamp mat 93 is provided on the upper surface of a base 113 provided on the flat portion 42 of the support substrate 41. The stamp mat 93 is made of a resin having elasticity, and is provided to form a clearer impression than printing on a hard surface.

  As a configuration for performing printing by the stamp 94, a first connection port 121 and a second connection port 122 are provided on the left main body side plate 13 constituting the main body frame 12 as shown in FIGS. The first connection port 121 is connected to the other end of a first outer pipe 124 having one end connected to an air source 123 (not shown in FIG. 1). The first connection port 121 is connected to an electromagnetic valve 126 provided on the back surface of the left main body side plate 13 via a first inner pipe 125 (not shown in FIG. 1). For this reason, air compressed by a compressor or the like is supplied from the air source 123 to the electromagnetic valve 126 via the first inner and outer pipes 124 and 125. As shown in FIG. 4, the electromagnetic valve 126 is a 2-position 3-port electromagnetic switching valve. One of the remaining two ports of the solenoid valve 126 is open to the atmosphere. The second connection port 122 is connected to the other port of the electromagnetic valve 126 via a second inner pipe 127 (not shown in FIG. 1). One end of the second outer pipe 128 is connected to the second connection port 122. When the electromagnetic solenoid provided in the electromagnetic valve 126 is turned off, the insides of the second inner and outer pipes 127 and 128 are opened to the atmosphere. On the other hand, when the electromagnetic solenoid is ON, the second inner and outer pipes 127 and 128 are communicated with the air source 123 through the first inner and outer pipes 124 and 125 and the electromagnetic valve 126, and the compressed air is supplied to the second inner and outer pipes 127 and 128. .

  As shown in FIG. 8, a cylinder 131 is provided on the mounting portion 99 of the support member 96. The cylinder 131 is fixed by a fixing screw 133 with the rod 132 facing downward so that the rod 132 is inserted into the through hole 111 of the mounting portion 99. Further, as shown in FIG. 4, a pressing plate 132 a is fixed to the tip of the rod 132. The pressing plate 132 a is also fixed to the upper surface portion 105 of the housing member 101. Of the pair of ports provided in the cylinder 131, the second outer pipe 128 is connected to a port 134 (upper port 134) located on the upper side. The lower port 135 (see FIG. 4) is open to the atmosphere.

  Therefore, in FIG. 4, when the electromagnetic solenoid of the electromagnetic valve 126 is turned on, compressed air is supplied from the second outer pipe 128 to the upper port 134 of the cylinder 131. As a result, the rod 132 protrudes downward, and a force is applied downward to the housing member 101 via the pressing plate 132a. As a result, the accommodating member 101 and the stamp 94 accommodated therein move downward. On the other hand, when the electromagnetic solenoid of the electromagnetic valve 126 is turned off, the second outer pipe 128 is opened to the atmosphere, so the compressed air that has pressed a piston (not shown) in the cylinder 131 is discharged to the atmosphere. As a result, the rod 132 returns to the non-projecting state, and the accommodating member 101 and the stamp 94 accommodated therein also return to their original positions. The electromagnetic valve 126, the cylinder 131, and the like constitute pressure contact means.

  As shown in FIG. 5, a detection switch 136 for detecting whether the rocking body 61 of the cutting device 23 is in a normal state or a rotating state on the back surface of the right main body side plate 14 constituting the main body frame 12. Is provided. A plate piece 137 capable of pressing the pressing pin 136a of the detection switch 136 is provided at the tip of the restricting piece 68 provided in the main body 63 of the rocking body 61. The plate piece 137 presses the pressing pin 136a when the swinging body 61 is in the normal position, and releases the pressing when it is in the rotating position. The detection switch 136 is turned on when the pressure pin 136a is pressed and released from the pressed state, and outputs a detection signal. As shown in FIG. 4, the electromagnetic valve 126 is connected to the detection switch 136, and the electromagnetic solenoid of the electromagnetic valve 126 is turned on / off depending on the presence / absence of a detection signal from the detection switch 136. Therefore, the electromagnetic solenoid of the electromagnetic valve 126 is turned on / off in conjunction with the operation of the oscillating body 61.

  Next, the operation of the stamp device 91 configured as described above will be described.

  When the oscillator 61 is in the normal state, the switch of the detection switch 136 is OFF, so the electromagnetic solenoid is also OFF, and the second outer pipe 128 is opened to the atmosphere. For this reason, the rod 132 of the cylinder 131 is in a non-projecting state. As shown in FIG. 9A, printing with the stamp 94 is not performed in this state. When the wrapping film 17 is pulled out from the film roll 19 or the pulled wrapping film 17 is wound around the article H to be packaged prepared in front of the manual wrapping device 11, the swinging body 61 is in the normal state, and therefore the wrapping film 17 Is not printed. When the packaging film 17 is pressed in front of the manual packaging device 11 so as to melt the packaging film 17 with the cutter 62, the rocking body 61 rotates from the normal position to the rotation position, and the detection switch 136 is turned on. Become. As a result, the electromagnetic solenoid is also turned on, and compressed air is supplied to the second outer pipe 128. Then, as shown in FIG. 9B, the rod 132 of the cylinder 131 protrudes, so that the housing member 101 and the stamp 94 housed therein move downward. As a result, the printing portion of the stamp 94 is pressed against the surface of the packaging film 17 on the stamp mat 93 and printed on the surface. Therefore, the printed packaging film 17 used for the next packaging operation is prepared as the packaging film 17 is melted.

  As a fourth feature, the manual packaging device has a configuration in which the printing position by the stamp device 91 is changed back and forth. Specifically, it has the following configuration, which will be described with reference to FIG.

  As shown in FIG. 3, the flat portion 42 of the support substrate 41 is formed with fixing holes 141 each having an oval shape along the front-rear direction at both left and right ends thereof. The support substrate 41 is fixed to the upper plate 21 by tightening a fixing screw in a screw hole provided in the upper plate 21 through the fixing hole 141. Then, if the fixing screw 143 is loosened, the support substrate 41 can slide in the front-rear direction. For this reason, if the support substrate 41 is slid in the front-rear direction in the range where the fixing hole 141 is formed, the film pressing device 22 is fixed at a desired position in the front-rear direction. The upper plate 21 has a plurality of screw holes 142 formed in the front-rear direction. If the screw hole 142 provided with the fixing screw 143 is appropriately changed, the position of the film pressing device 22 in the front-rear direction can be further changed.

  Next, the operation of the above configuration will be described.

  A fixing screw 143 is provided in a desired screw hole 142, and the support substrate 41 of the film pressing device 22 is slid in the front-rear direction with the fixing screw 143 being loosened to adjust the stamp device 91 to a desired position. Then, the fixing screw 143 is tightened at that position to fix the film pressing device 22 to the upper plate 21. Thereby, it prints on the packaging film 17 in the specific position of the front-back direction.

  When changing the print position from the specific position in the front-rear direction, the fixing screw 143 is loosened and the support substrate 41 is slid in the front-rear direction within the range of the fixing hole 141, or the screw hole 142 is changed. . The fixing screw 143 is tightened at the position after the change to fix the film pressing device 22 to the upper plate 21. Since the packaging film 17 does not move in the front-rear direction when printing by the stamp 94 is performed, if the front-rear position of the film pressing device 22 is changed, the relative position in the front-rear direction between the stamp unit 92 fixed to the device is changed. Is changed. For this reason, the packaging film 17 is printed at a position different from the specific position in the front-rear direction. In this way, the printing position by the stamp device 91 can be appropriately changed to a desired position in the front-rear direction.

  As a fifth feature, the manual packaging device has a configuration in which the printing position by the stamp device 91 is changed in the left-right direction. Specifically, it has the following configuration, which will be described with reference to FIGS. 10 is a cross-sectional view showing the support mechanism, FIG. 11 is a plan view showing a pair of holding members, and FIG. 12 is an enlarged cross-sectional view showing the right holding member.

  As shown in FIG. 10, the rear connecting plate 16 constituting the main body frame 12 is provided with a pair of holding members 151 and 152 as restricting members for holding the film roll 19. Of the both clamping members 151, 152, the left clamping member 151 (left clamping member 151) includes a fixed plate 153 fixed to the rear connecting plate 16. As shown in FIG. 11, a fixing hole 154 having an oval shape is formed in the fixing plate 153 along the left-right direction. The left clamping member 151 is fixed to the rear connection plate 16 by tightening the fixing screw 155 in the screw hole formed in the rear connection plate 16 through the fixing hole 154. If the fixing screw 155 is loosened, the fixing plate 153 can slide in the left-right direction. For this reason, if the fixing plate 153 is slid in the left-right direction within the range where the fixing hole 154 is formed, the left clamping member 151 can be fixed at a desired position in the left-right direction. At the end of the fixed plate 153 on the film roll 19 side (right side), a sandwiching plate 156 formed by bending the end upward is provided. The sandwiching plate 156 contacts the left end of the film roll 19 and sandwiches the film roll 19 together with a right sandwiching member 152 (right sandwiching member 152) described later.

  As shown in FIG. 12, the right clamping member 152 includes a first fixing plate 157. A second fixing plate 158 is provided between the first fixing plate 157 and the rear connection plate 16. The second fixing plate 158 is formed so that the length in the left-right direction is longer than that of the first fixing plate 157. Both the fixing plates 157 and 158 are joined by welding or the like with the end on the opposite side (right side) opposite to the film roll 19 being aligned. The first and second fixing plates 157 and 158 are formed with fixing holes 159 having an oval shape along the left-right direction. The right clamping member 152 is fixed to the rear connection plate 16 by tightening the fixing screw 160 in the screw hole formed in the rear connection plate 16 through the fixing hole 159. If the fixing screw 160 is loosened, both the fixing plates 157 and 158 can slide in the left-right direction. For this reason, if both the fixing plates 157 and 158 are slid in the left-right direction within the range where the fixing hole 159 is formed, the right clamping member 152 can be fixed at a desired position in the left-right direction.

  A screw attachment plate 161 formed by bending the end portion upward is provided at the left end portion of the first fixing plate 157. A through-hole 162 is formed in the upper part of the screw mounting plate 161, and an adjustment screw 163 is provided in the through-hole 162 so that the tip portion is directed leftward. A pressing plate 164 as a pressing member formed by bending the end portion upward is provided at the left end portion of the second fixed plate 158. The pressing plate 164 contacts the right end of the film roll 19 and clamps the film roll 19 together with the above-described sandwiching plate 156 of the left sandwiching member 151. Further, when the adjusting screw 163 is tightened, the tip thereof presses the pressing plate 164 and the pressing plate 164 is deformed to the film roll 19 side. Conversely, if the adjustment screw 163 is loosened, the pressing plate 164 returns from its deformed state to its non-deformed state according to the amount by which the adjustment screw is loosened due to its restoring force. For this reason, the amount of deformation of the pressing plate 164 toward the film roll 19 is adjusted by adjusting the tightening amount of the adjusting screw 163.

  Next, the operation of the pair of holding members 151 and 152 configured as described above will be described.

  The left and right clamping members 151 and 152 are loosened by loosening the fixing screws 155 and 160 so that the holding plate 156 is in contact with the left end of the film roll 19 and the pressing plate 164 is in contact with the right end and the film roll 19 is disposed at a desired left and right position. Adjust the slide. Then, the fixing screws 155 and 160 are tightened at the adjusted position to fix the left and right holding members 151 and 152 to the rear connecting plate 16. Thereby, the film roll 19 is arrange | positioned in the specific position of the left-right direction. And if the position of the film roll 19 is specified, since the relative position in the left-right direction is specified with the stamp portion 92 that cannot be changed in the left-right direction, the packaging film 17 has a specified position in the left-right direction. Is printed.

  When changing the printing position from the specific position in the left-right direction, the fixing screws 155, 160 are loosened, and the left and right clamping members 151, 152 are slid in the left-right direction within the range of the fixing holes 154, 159, respectively. The adjustment takes into consideration that the film roll 19, the sandwiching plate 156 and the pressing plate 164 abut after the position change in the left-right direction. When the fixing screws 155 and 160 are tightened at the adjusted position to fix the left and right holding members 151 and 152 to the rear connecting plate 16, the position of the film roll 19 in the left and right direction is changed. Thereby, since the relative position with respect to the stamp part 92 is also changed, the packaging film 17 drawn out from the film roll 19 is printed at a position different from the specific position in the left-right direction. In this way, the printing position by the stamp device 91 can be appropriately changed to a desired position in the left-right direction.

  Further, when the adjustment screw 163 of the right clamping member 152 is tightened in a state where the left and right clamping members 151 and 152 are fixed to the rear connecting plate 16, the pressing plate 164 is pressed against the film roll 19 by the deformation. As the adjustment screw 163 is tightened, the pressing force becomes stronger, and accordingly, the film roll 19 becomes difficult to rotate. On the contrary, as the adjustment screw 163 is loosened, the pressing force is relaxed, and the film roll 19 is easily rotated accordingly. Therefore, the left and right clamping members 151 and 152 have not only a change of the left and right positions but also a function of adjusting the ease of rotation of the film roll 19.

  Since the pressing plate 164 can be deformed in this way, when the positions of the left and right holding members 151 and 152 are adjusted, the contact state between the film roll 19 and the holding plate 156 and the pressing plate 164 is not good. Even if it is complete, the imperfection is absorbed by the deformation of the pressing plate 164.

  As described above in detail, the present embodiment has the following excellent effects.

  In the present embodiment, the upper plate 21 is arranged at a position lower than the upper edge of the main body side plates 13, 14, and rising plates 73, 74 are provided at both front and rear ends thereof, and separated from the upper surface of the upper plate 21. In this state, the packaging film 17 is drawn out. Thereby, even when the packaging film 17 provided with the adhesive portions 17a and 17b is used as in the present embodiment, the entire adhesive portions 17a and 17b can be prevented from sticking to the upper plate 21. Thereby, sticking to the upper board 21 of the packaging film 17 is suppressed to the minimum.

  In the present embodiment, a hinge device 81 is provided at the left end portion of the crossover plate 15 provided with the presser rollers 52 and 56 so that the crossover plate 45 rotates from the closed state to the open state. As a result, when the work is performed in which the hand interferes with the pressing rollers 52 and 56 and the crossing plate 45, the work can be easily performed if the crossing plate 45 is opened.

  In the present embodiment, the packaging film 17 is printed by printing on the packaging film 17 using the stamp 94. For this reason, compared with the case where the printing apparatus by thermal transfer is used, it is excellent in the following points. First, the heat does not cause shrinkage or perforation in the printed portion. In addition, there is no waiting time, and the user's stress at the beginning of work can be alleviated. Furthermore, the stamp 94 is less expensive than electronic components such as a thermal head, and can be easily procured by using a commercially available one. For this reason, the manual packaging apparatus 11 with a printing function can be provided at low cost.

  In the present embodiment, the stamp 94 is detachable from the stamp accommodating member 101, and the stamp accommodating member 101 is formed in accordance with the specifications of the commercially available stamp 94. For this reason, when it is necessary to replace the stamp 94 due to a change in the print contents, the replacement is possible, and the stamp 94 can be easily procured. Thereby, the cost of the manual packaging apparatus 11 can be reduced.

  In this embodiment, by loosening the fixing screw 143, the mounting position of the support substrate 41 is slidably adjusted in the front-rear direction within the range of the fixing hole 141. Further, if the plurality of screw holes 142 formed in the front-rear direction are appropriately changed, the position in the front-rear direction is changed in a wider range. If the front and rear position of the support substrate 41 is changed, the front and rear relative positions of the packaging film 17 and the stamp 94 are changed, and the marking position on the packaging film 17 is also changed. Thereby, the versatility of the manual packaging apparatus 11 with a printing function, such as changing a stamping position suitably according to the kind of the packaging film 17, can be improved.

  Then, presser rollers 52 and 56 and a stamp portion 92 are provided on the transition plate 45 supported by the support substrate 41. For this reason, compared with the structure which provides both in the respectively separate member, both structures can be put together compactly. Further, since the pressing rollers 52 and 56 are provided before and after the stamp portion 92, the packaging film 17 located below the stamp 94 can be prevented from being lifted up and down when the packaging film 17 is printed. Thereby, the stamp part of the packaging film 17 can be held in an appropriate state, and the occurrence of printing defects can be suppressed.

  In the present embodiment, the compressed air is supplied to and discharged from the cylinder 131 in conjunction with the swinging motion of the swinging body 61 so that the stamping operation by the stamp 94 and the returning operation from the stamping state are performed. For this reason, if the oscillating body 61 is turned and the packaging film 17 is cut, the stamped packaging film 17 used for the next packaging operation is prepared. As a result, an operation only for marking the packaging film 17 becomes unnecessary, and the packaging work by the stamped packaging film 17 can be made efficient.

  In the present embodiment, the film roll 19 is clamped by a pair of clamping members 151 and 152. Thereby, since it is suppressed that the film roll 19 shakes right and left when pulling out the packaging film 17 from the film roll 19, the drawing of the packaging film 17 can be performed smoothly. The clamping members 151 and 152 are configured to be slidably adjusted in the left-right direction within the range of the fixing holes 154 and 159. As a result, the left and right relative positions of the stamp portion 92 and the packaging film 17 are changed, and the marking position of the packaging film 17 is changed. Thereby, the versatility of the manual packaging apparatus 11 with a printing function, such as changing a stamping position suitably according to the kind of packaging film 17, can be improved. As a configuration for changing the positions of the holding members 151 and 152, it is sufficient that the fixing holes 154 and 159 have an oval shape, and it is possible to change the marking position to the left and right with a simple and inexpensive configuration.

  In the present embodiment, the pressing amount of the pressing plate 164 is adjusted to adjust the ease of rotation of the film roll 19. Since the operator pulls out the packaging film 17 from the film roll 19 differently, adjusting the ease of rotation according to the operator may cause the packaging film 17 to be pulled out excessively or difficult to pull out. Can be prevented. Further, even if the contact state between the film roll 19 and the holding plate 156 and the pressing plate 164 is incomplete, the imperfection can be absorbed by adjusting the pressing amount of the pressing plate 164, and the holding can be performed reliably. it can.

  In this embodiment, an electromagnetic solenoid 231 and a wire cable 224 connected to the electromagnetic solenoid 231 are provided as a configuration for performing printing by the stamp 94. As shown in FIG. 15, the electromagnetic solenoid 231 is provided inside the main body frame 12. The electromagnetic solenoid 231 is provided with a plunger 232, and the plunger 232 is drawn toward the electromagnetic solenoid 231 by energizing the electromagnetic solenoid 231. The wire cable 224 includes an inner wire 224a and an outer wire 224b outside the inner wire 224a, and the inner wire 224a can slide in the outer wire 224b.

  A connection port 221 is formed in the left main body side plate 13, and one end portion of the outer wire 224 b is fitted into the connection port 221 from the outside of the main body frame 12. Thus, one end portion of the outer wire 224b is fixed to the main body frame 12. One end of the inner wire 224 a extends from the connection port 221 into the main body frame 12 and is connected to the plunger 232.

  A cylindrical outer wire fixing member 225 is attached to the through hole 211 formed in the upper surface portion 299 of the support member 296. The outer wire fixing member 225 is attached to the upper surface portion 299 by inserting one end of the outer wire fixing member 225 into the through hole 111 from below and screwing the nut 226 from above. From the other end of the outer wire fixing member 225, the other end of the outer wire 224b is fitted and fixed.

  The other end portion of the inner wire 224a passes through the outer wire fixing member 225, the coil spring 227 and the through hole 212 disposed between the upper surface portions 299 and 203. A spherical stopper member 228 is fixed to the end of the inner wire 224a. The stopper member 228 is locked to the locking member 229, and the locking member 229 is fixed to the upper surface portion 203 with a fixing screw 230. This prevents the end portion of the inner wire 224a from falling down from above the through hole 212. As shown in FIG. 15, the balance position of the coil spring 227 when the manual packaging device 11 is not in operation is set such that the lower end of the stamp 94 is positioned above the flat portion 297.

  As shown in FIG. 13, the wire cable 224 is pulled out to the left side of the main body frame 12 so as not to interfere with the packaging film 17, and then connected to the connection port 221 formed in the left main body side plate 13.

  In the above configuration, when the electromagnetic solenoid 231 is turned on by a signal from the detection switch 136, the plunger 232 is pulled toward the electromagnetic solenoid 231 side. As a result, the inner wire 224a having one end connected to the plunger 232 is also drawn toward the electromagnetic solenoid 231 side. Since the stopper member 228 at the other end of the inner wire 224a is locked to the upper surface portion 203 of the driving force transmission member 201, a downward force is applied to the upper surface portion 203 by the inner wire 224a. As a result, the coil spring 227 is contracted, and the driving force transmission member 201, the stamp accommodating member 101 fixed thereto, and the stamp 94 accommodated therein are lowered.

  On the other hand, when the electromagnetic solenoid 231 is turned off by a signal from the detection switch 136, the plunger 232 returns to the original position. Then, the downward force applied to the upper surface portion 203 by the inner wire 224a is released. As a result, an upward force is applied to the upper surface portion 203 by the restoring force of the coil spring 227, and the driving force transmission member 201, the stamp accommodating member 101, and the stamp 94 are raised and returned to their original positions.

  Next, the operation of the stamp device 91 configured as described above will be described.

  When the oscillator 61 is in the normal state, the switch of the detection switch 136 is OFF, so the electromagnetic solenoid 231 is also OFF, and the inner wire 224a is not drawn toward the electromagnetic solenoid. For this reason, the coil spring 227 is in a balanced position. As shown in FIG. 16A, printing with the stamp 94 is not performed in this state. When the packaging film 17 is pressed in front of the manual packaging device 11 so as to melt the packaging film 17 with the cutter 62, the rocking body 61 rotates from the normal position to the rotation position, and the detection switch 136 is turned on. Become. As a result, the electromagnetic solenoid 231 is also turned ON, and the inner wire 224a is drawn toward the electromagnetic solenoid 231 side. Then, as shown in FIG. 16 (b), the stamp 94 is lowered and the printed portion is pressed against the surface of the packaging film 17 on the stamp mat 93 and printed on the surface. Therefore, the printed packaging film 17 used for the next packaging operation is prepared as the packaging film 17 is melted.

  As shown in FIG. 16, the packaging film 17 is in contact with the first and second sheet pressing portions 246b and 297b, and is prevented from rising. In addition, the packaging film 17 faces the lower surface of the flat surface portion 246 of the transition member 245 in a state before the stamping. Thereby, the packaging film 17 is prevented from being lifted on both the left and right sides of the stamping position.

  As described above in detail, the present embodiment has the following excellent effects.

  In the present embodiment, by loosening the fixing screw 250, the mounting position of the support member 296 can be slidably adjusted in the left-right direction within the range of the fixing hole 259. For this reason, the stamping position of the packaging film 17 can be changed by changing the relative position between the stamp portion 92 and the packaging film 17. Thereby, the versatility of the manual packaging apparatus 11 can be improved, such as changing a stamping position suitably according to the kind of the packaged article H. In particular, fine adjustment of the stamping position is facilitated by adopting a configuration in which the stamp portion 92 side is slid left and right.

  Moreover, in this embodiment, since it has the structure which slide-adjusts the clamping members 151 and 152 of the film roll 19, both the film roll 19 and the stamp part 92 can be slide-adjusted to the left and right. For this reason, even if the manual packaging device 11 is small, it is possible to expand the adjustment range of the stamp stamping position by sliding both to the side away from each other. Furthermore, in this embodiment, it has the structure which slide-adjusts the attachment position of the support substrate 41 in the range of the fixing hole 141 in the front-back direction. Thereby, the marking position on the packaging film 17 can be changed in the front-rear and left-right directions, and the versatility of the manual packaging device 11 with a printing function can be further enhanced.

  In this embodiment, by turning on the electromagnetic solenoid 231, the inner wire 224 a is drawn and the stamp portion 92 is lowered. Further, by turning off the electromagnetic solenoid 231, the stamp 94 was returned to the original position by the restoring force of the coil spring 227. Thereby, it is possible to perform the stamping operation and the return operation with a simple configuration. Further, the return position of the stamp 94 may be such that the printing portion of the stamp 94 is positioned above the flat surface portion 246 of the crossover member 245, and the accuracy of the return position is not so required. For this reason, even when the elastic force of the coil spring 227 slightly decreases due to the change over time, the stamp 94 can be returned to the predetermined return position.

  In the present embodiment, the first sheet pressing portion 246b is formed by a bent portion at the rear end of the flat portion 246 in the transition member 245. In addition, the second sheet pressing portion 297 b was formed by a bent portion at the front end of the flat portion 297 in the support member 296. As a result, the first and second presser rollers 52 and 56 used in the first embodiment are not required, and the cost can be reduced, and the packaging film 17 can be prevented from being lifted with a simple configuration. Also, the first and second sheet pressing portions 246b and 297b are formed by smooth curved surface portions. Thereby, when the packaging film 17 is pressed by the first and second sheet pressing portions 246b and 297b, it is possible to prevent the packaging film 17 from being holed or torn. Furthermore, the free end portion at the front end of the second sheet pressing portion 297b is on the drawing direction side of the packaging film 17. Thereby, when pulling out packaging film 17, it can control that a hole, a tear, etc. occur in packaging film 17 in the front end part of the 2nd sheet press part 297b.

  In the present embodiment, the packaging film 17 is opposed to the lower surface of the flat portion 246 of the crossover member 245. Thereby, the packaging film 17 can be prevented from being lifted on both the left and right sides of the stamping position. As a result, the stamped portion of the packaging film 17 can be held in an appropriate state, and the occurrence of printing defects can be suppressed.

  In the present embodiment, the guide member 109 is fixed to the base portion 298 of the support member 296 in a state where the lower end of the guide member 109 is in contact with the flat portion 297 of the support member 296. That is, the guide member 109 was fixed so as to be supported by the back surface portion 109b and the lower end portion thereof. For this reason, when the interposition member 106 integrated with the stamp housing member 101 or the like slides up and down in the groove 109c of the guide member 109, compared to the case of the first embodiment supported only by the back surface portion 109b. Improves stability.
