A cutting tool, a shrink tunnel, and the like for fusing each object 9 are provided.

  The incision forming unit 2 performs the opening incision shown in FIG. 2 (hereinafter simply referred to as “cutting”) at predetermined intervals in the sending direction of the packaging film 7 while the packaging film 7 that is a shrink film is being sent from the film roll 6. (Referred to as “cut”) 8. This notch 8 is a part that becomes a trigger for opening the package 10 after shrink-wrapping the article 9 (see FIG. 5).

  The folding processing unit 3 has a configuration for bending the opened label tape 11 sent from the tape roll 12 of the opened label tape 11. The cutting unit 4 has a configuration for cutting the sent open label tape 11 so as to have an appropriate length as the open label 13 to be attached to the region where the cut 8 is formed. The affixing unit 5 has a configuration for affixing the unsealing label 13 to an area of the packaging film 7 where the cuts 8 are formed.

  The cut forming unit 2 will be described. The cut forming part 2 is arranged in the middle of the delivery path of the packaging film 7 delivered from the film roll 6. That is, it is disposed downstream in the delivery direction with respect to the film roll 6 and upstream in the delivery direction with respect to the sticking portion 5.

  The notch forming unit 2 sandwiches the packaging film 7 between the front surface as one surface and the back surface as the other surface, so that the cutting blade 14 and the receiving blade 14 move in conjunction with the moving force of the packaging film 7. A stand 15 is provided. The cutting blade 14 is disposed on the front surface side of the packaging film 7, and the cradle 15 is disposed on the back surface side of the packaging film 7.

  The cutting blade 14 is supported by the blade support portion 16 so as to be movable up and down. The blade support portion 16 includes a cutting blade cylinder device 17 having a cutting blade 14 attached to the tip. The cutting blade 14 is moved up and down as the cutting blade cylinder device 17 expands and contracts. The cutting blade 14 is housed in the outer cylinder member 18 in the upper position. When the cutting blade cylinder device 17 extends, the cutting blade 14 moves down together with the outer cylinder member 18 and moves so as to protrude downward with respect to the outer cylinder member 18. In addition, the front-end | tip part of the main body of the cutting blade 14 is a part which forms the cut 8 in the packaging film 7, and the front-end | tip part is cut diagonally.

  The cradle 15 is supported by the cradle support part 19 via the support base 20. The cradle 15 is disposed at a position that is always opposed to the cutting blade 14 in the vertical direction. The cradle 15 includes an insertion recess 21 into which the cutting blade 14 can be inserted. The outer cylinder member 18 and the cutting blade 14 can be moved toward and away from the packaging film 7, while the cradle 15 can be reciprocated only in the horizontal direction without moving up and down. The upper end surface 15 a of the cradle 15 is always in contact with the back surface of the packaging film 7. That is, the packaging film 7 is sent out so as to slide on the upper end surface 15 a of the cradle 15.

The cradle support portion 19 includes a guide member 22 (guide bar) that guides the cradle 15 so as to reciprocate in the horizontal direction. The cradle support unit 19 includes one side wall 23 that restricts the position of the cradle 15 on one side (upstream in the sending direction) on one side of the support base 20. The cradle support portion 19 includes a spring (biasing means) 24 that biases the cradle 15 to one side. The spring 24 is disposed between the side portion of the cradle 15 and the other side wall 25 provided on the support base 20 of the cradle support portion 19. The cradle support portion 19 includes a regulating member 26 (a bowl-shaped member) for regulating the amount of movement of the cradle 15 to the other side. The regulating member 26 penetrates the other side wall 25 in the horizontal direction and is laterally It is comprised so that the position of can be adjusted.
ing.

  The support 20 of the cradle support 19 and the blade support 16 are connected in the vertical direction by a connecting member 27. Since the support base 20 and the blade support portion 16 are connected by a connecting member 27, the cutting blade 14 and the receiving base 15 are configured to be capable of reciprocating in synchronization with the horizontal direction.

  In the notch forming part 2, when the packaging film 7 is fed while being tensioned by a plurality of rollers R1 with a force drawn out on the downstream side of the film roll 6, the feeding direction of the packaging film 7 A cut 8 is formed on the packaging film 7 at every predetermined interval in the delivery direction using the output power to.

  That is, when the cutting blade cylinder device 17 extends and the outer cylinder member 18 and the cutting blade 14 move downward, and the lower end surface 18a of the outer cylinder member 18 contacts the surface of the packaging film 7, The packaging film 7 is sandwiched between the lower end surface 18 a of the outer cylinder member 18 and the upper end surface 15 a of the cradle 15. At this time, the packaging film 7 is strongly sandwiched between the lower end surface 18 a of the outer cylinder member 18 and the upper end surface 15 a of the cradle 15.

  When the packaging film 7 is strongly clamped between the lower end surface 18a of the outer cylinder member 18 and the upper end surface 15a of the cradle 15, the force for pulling out the packaging film 7 is applied to the outer cylinder member 18 and the cradle 15. Communicated. And since the support stand 20 and the blade support part 16 are connected by the connection member 27 in the up-down direction, the outer cylinder member 18 and the receiving stand 15 resist the elastic force of the spring 24, and are downstream in the delivery direction. Move to.

  When the outer cylinder member 18 and the cradle 15 are moved to the downstream side in the delivery direction, the cutting blade 14 protrudes from the outer cylinder member 18 and a notch 8 is formed at a predetermined position of the packaging film 7. . When the outer cylinder member 18 and the cradle 15 are moved in the horizontal direction (downstream in the delivery direction) by a necessary stroke, the cutting blade cylinder device 17 is contracted, and the outer cylinder member 18 and the cutting blade 14 are replaced with the packaging film 7. Leave upwards.

  As a result, the outer cylinder member 18 and the cradle 15 do not receive the output of the packaging film 7, and the elasticity of the spring 24 causes the support base 20 and the blade support portion 16 to have the cutting blade 14 away from the packaging film 7. In the detached state, it moves to one side (upstream side) in the sending direction. The movement of the outer cylinder member 18 and the cradle 15 by a necessary stroke is detected by, for example, a proximity switch. The required stroke is a distance corresponding to a time required for the cutting blade 14 to protrude from the outer cylinder member 18 to form the cut 8.

  The notch forming unit 2 operates so as to form the notch 8 at a predetermined position set in advance. Thus, in the notch formation part 2, when the packaging film 7 is sent out with the force withdraw | derived to the downstream of the film roll 6, using the sending output in the sending direction of the packaging film 7 is used. Since the cuts 8 are formed at predetermined intervals in the sending direction with respect to the packaging film 7, the packaging film 7 is driven only by the driving force of the actuator called the cutting blade cylinder device 17 as the driving force. An incision 8 can be formed.

  Next, the bending process part 3 is demonstrated. In the present embodiment, the bending unit 3 applies the unwrapped label tape 11 that is sent from the tape roll 12 and serves as the unsealed label 13 to an area on one side in the width direction (hereinafter simply referred to as “one side” that does not reach half of its width). It is configured so that it can be bent with respect to the adhesive surface 11a. In this case, the opening label tape 11 is an adhesive tape having a non-adhesive surface on the front surface and an adhesive surface on the entire back surface.

The flanged roller 36 is rotatable around a horizontal shaft member 36a along a horizontal plane perpendicular to the delivery direction.

  The barbed roller 36 is used for barking to the extent that a crease is formed at the rising base end of the opened opening label tape 11, and the outer peripheral surface of the barbed roller 36 is on the other side in the width direction. In comparison, the width direction one side is formed to have a large diameter, and the outer periphery of the width direction one side end is formed in an edge shape. The outer periphery of one end in the width direction of the flanged roller 36 is in contact with the adhesive surface 11a of the opened label tape 11 being fed, and rotates around the horizontal shaft member 36a as the opened label tape 11 is moved.

  The flanged roller 36 is disposed to face the guide plate 35, and the outer periphery of one end in the width direction of the flanged roller 36 contacts the adhesive surface 11 a of the opened label tape 11, so that the opened label tape 11 is sent out. By rotating around the horizontal shaft member 36a with the movement, the rising proximal end of the opened label tape 11 is brazed.

  The bent portion 32 is disposed on the downstream side in the delivery direction with respect to the pair of opposing members. The bent portion 32 feeds a folded piece (corresponding to a tilting member) that folds the one side region 28 that has passed between the pair of opposing members gradually closer to the adhesive surface 11a with respect to the pair of opposing members. Provided on the downstream side. A plurality of folded pieces are provided, and the first folded piece 40, the second folded piece 41, and the third folded piece 42 are arranged in this order from the upstream side in the delivery direction to the downstream side in the delivery direction.

  Each folded piece is formed integrally with the fixed piece 43 fixed to one side end in the width direction of the narrow member 34 and the upper end of the fixed piece 43, and to the upper surface of the narrow member 34 with respect to the fixed piece 43. And an inclined piece 44 that is inclined toward the surface. In the folded piece, the inclined angle of the inclined piece 44 is configured to be steeply inclined toward the upper surface of the narrow member 34 in the order of the first folded piece 40, the second folded piece 41, and the third folded piece 42. .

  The bent portion 32 further includes a pressing roller disposed on the downstream side in the feeding direction with respect to the folded piece. The presser roller includes an upper roller 45 and a lower roller 46 that are arranged to face each other in the vertical direction. The upper roller 45 and the lower roller 46 are supported so as to be rotatable around other horizontal shaft members 45a and 46a parallel to the horizontal shaft member 36a, respectively. The upper roller 45 is a driving roller. The opening label tape 11 is sandwiched between the lower roller 46 and the opening label tape 11 is sent out by driving of the driving motor 45A.

  The upper roller 45 and the lower roller 46 sandwich not only the one side region 28 of the opening label tape 11 but also the entire opening label tape 11 from above and below so that the one side region 28 contacts the adhesive surface of the opening label tape 11. It is configured.

  In the bending portion 3 having the above-described configuration, the opening label tape 11 is guided in the feeding direction by the non-adhesive surface by the guide portion 30 and does not reach half the width of the opening label tape 11 guided by the guide portion 30. The one side region 28 is raised toward the other side in the width direction by the guide plate 35 of the rising portion 31 so as to bring the adhesive surfaces 11a closer to each other.

  When the one side region 28 passes between the guide plate 35 and the flanged roller 36, the one side region 28 of the opened label tape 11 is raised by the outer periphery of one end in the width direction of the flanged roller 36. The rising base end is brazed, and then the one side region 28 is adhered to the adhesive surface 11a toward the downstream side in the delivery direction by the first fold piece 40, the second fold piece 41, and the third fold piece 42 of the bent portion 32. The unsealed label tape 11 is sandwiched between the upper roller 45 and the lower roller 46, and the one side region 28 is adhered to the adhesive surface 11a.

The drum main body 52 is rotatably supported around a horizontal axis member 52a along the feeding direction of the packaging film 7 in which the cut 8 is formed in the cut forming portion 2.

  The cutting unit 4 includes a rotation driving unit 53 for rotating the horizontal shaft member 52a. The presser roller 51 presses the unsealed label tape 11 with the drum body 52 from above, and is configured to be able to approach and separate from the outer peripheral surface of the drum body 52 by operating a lever (not shown). Yes.

  The suction portion 47 includes suction means (not shown) that makes the inside of the drum main body 52 have a negative pressure. On the outer peripheral surface of the drum body 52, suction holes 55 communicating with the internal space are formed at predetermined intervals in the circumferential direction and the axial direction. Grooves 56 extending in the axial direction are formed on the outer peripheral surface of the drum main body 52 at predetermined intervals in the circumferential direction. The space | interval in which the groove | channel 56 is formed substantially corresponds to the size of the label 13 for opening affixed on the packaging film 7 so that the notch 8 formed in the packaging film 7 may be included.

  The cutting blade 48 cuts the opening label tape 11 entering the groove 56 formed on the outer peripheral surface of the drum main body 52 and adsorbed on the outer peripheral surface of the drum main body 52 at intervals of the groove 56 and the opening label 13. The tip is formed in a plate shape with a sharp tip. The cutting blade 48 is attached to the tip of a cylinder device 57 that is an actuator, and is configured to approach and separate from the groove 56. The cutting blade 48 is disposed so as to correspond to an intermediate position of the height of the drum main body 52 in the vertical direction.

  In the cutting part 4, the opened label tape 11 whose one side region 28 is bent in the bending part 3 is adsorbed so as to be sequentially applied to the outer peripheral surface of the drum body 52, and the adsorbed opened label tape 11 is When the cutting blade 48 enters the groove 56, it is cut into the size of the label 13 for opening.

  The unsealed label tape 11 that has been sent to the downstream side in the sending direction through the bending processing section 3 is sent to the downstream side in the sending direction at a lower position of the drum body 52. The unsealing label tape 11 is sent out with the adhesive surface 11a up in the bending portion 3, and is sucked into the drum body 52 and rotated together with the drum body 52 in the attaching portion 5, so that the adhesive surface 11a is lowered.

The opening label tape 11 delivered from the tape roll 12 is bent with respect to the adhesive surface 11a in a region on one side in the width direction that does not reach half of its width, and the opening label delivered by the cutting unit 4 The tape 11 is cut to an appropriate length as the opening label 13 to be attached to the region where the cut 8 is formed in the packaging film 7, and the opening label 13 is attached to the region of the cut 8 by the attaching portion 5. Then, the article 9 is packaged with the packaging film 7.

  The opening label tape 11 delivered from the tape roll 12 is cut after being bent with respect to the adhesive surface 11a in a region on one side in the width direction that does not reach half of the width, thereby opening the label 13 Thus, since the region can be used as a handle when the opening label 13 is picked, the opening label 13 can be easily picked when the packaging film 7 is opened, and therefore the packaging film 7 is easily opened. Since the opening label 13 is formed by bending the pressure-sensitive adhesive tape with respect to the pressure-sensitive adhesive surface 11a in a region on one side in the width direction that does not reach half of its width, it is inexpensive.

  Moreover, about the cut formation part 2, the bending process part 3, the cutting | disconnection part 4, and the sticking part 5, the cut formation part 2 and the cutting part 4 are arranged in the delivery direction of the packaging film 7, and the sticking part 5 is cut | disconnected 4 The label sticking device has a configuration in which the cutting portion 4 and the bending processing portion 3 are arranged in the delivery direction of the unsealed label tape 11 with the direction substantially orthogonal to the delivery direction of the packaging film 7 as the delivery direction. As a whole, the arrangement can be made compact.

  The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. The same applies to the specific configuration of each part. As an example, the configuration of the cut forming portion 2 is not limited to the above embodiment. For example, in the above embodiment, the force for moving the packaging film 7 is used. The drive part which moves 14 and the receiving stand 15 with the film 7 for packaging can be provided, and the cut 8 can be formed in the film 7 for packaging. Further, the driving of the cutting blade 14 is not limited to the configuration by the cylinder device, and may be moved up and down by using the rotation of the cam.

  In the above embodiment, the opening label tape 11 is folded in a region on one side in the width direction that does not reach half of its width. However, depending on the direction of the cut 8 formed in the packaging film 7, the opening label tape 11 is opened. In some cases, the label tape 11 may be bent in a region on the other side in the width direction that does not reach half of its width.

  In the above-described embodiment, the bending unit 3 uses the first folded piece 40, the second folded piece 41, and the third folded piece 42 as the folded pieces. You may make it incline so that a part may approach the adhesion surface 11a. Further, the guide plate 35 and the folded piece can be integrally formed.

  In the cutting part 4, in the said embodiment, the groove | channel 56 over the axial direction was formed in the outer peripheral surface of the drum main body 52 of the adsorption | suction drum 50 for every circumferential direction predetermined space | interval. However, the suction drum 50 may not be provided, and the unsealed label tape 11 may be cut at predetermined intervals using a cutting blade while being sent downstream in the sending direction.

  In the above-described embodiment, the affixing unit 5 has exemplified a configuration in which the pressing roller 58 is intermittently pushed upward. However, the pressing roller 58 may be configured to constantly press the packaging film 7 upward.
