Description

Label fitting system

The present invention relates to a label fitting system for fitting a cylindrical label around the outer periphery of a container.

Conventionally, a container whose top surface is wider than the trunk is known. For example, among containers for storing yogurt or the like, there is a container having a pot portion for storing contents and a flange projecting outward from the upper end of the pot portion. In order to attach a cylindrical label to the outer periphery of such a container, a technique has been proposed in which a cylindrical label is inserted from the lower side of the container, and then the label is thermally contracted to adhere to the container.

For example, in Patent Document 1, a container pack in which three (or six in two columns × three rows) containers are integrally connected by a flange portion is continuously suspended and conveyed by an adsorption belt, and in the middle After the heat-shrinkable cylindrical label that is blown in an open state from the label supply unit provided below the adsorption belt is fitted around the pot portion of each container, the label is thermally contracted by the heating means. A label mounting device for mounting a label on the pot portion of each container is described.

JP-T-2015-525713

By the way, in the case of a configuration in which the cylindrical label is fitted to the container from the lower side, the cylindrical label may fall from the container after being fitted to the container and before being heat-shrinked. In Patent Document 1, in order to prevent the label from dropping, a plate is disposed on the lower side of the container after the label is fitted. By arranging the plate, the label fitted to the container is reliably prevented from falling.

However, in the technique of Patent Document 1, the label falls at the plate height. Since the plate is located below the lower end of the container, as a result, in the technique of Patent Document 1, the lower end height of the label is limited to be lower than the lower end height of the container. In other words, in the technique of Patent Document 1, the label cannot be fitted to the container in a state where the lower end height of the label is higher than the lower end height of the container, and there are many design restrictions. .

技術 Another possible technique for preventing the label from falling is to reduce the gap between the container and the label and prevent the label from falling due to the frictional force between the two. However, this technique has difficulty in practically managing the dimensions of the container and the label. Another technique is to spray the water around the container and use the surface tension of the water to prevent the label from falling. However, depending on the contents accommodated in the container, water spraying may not be possible for hygienic reasons. In other words, water spraying was not a useful technique.

Therefore, an object of the present invention is to provide a label fitting system that can hold a label fitted from the lower side at a desired height position.

The label fitting system according to the present invention includes a container transport device that moves a predetermined container in a predetermined transport direction while suspending and holding a cylindrical container, and a barrel portion of a container that is suspended and held by the container transport device. A label fitting unit that fits the label from below the container, and a holding member that holds the side surface of the cylindrical label fitted to the container are moved in translation with the container to convey the label A label conveying device.

In a preferred aspect, the label conveying device is configured to suck and hold the side surface of the cylindrical label.

In another preferred aspect, the label transport device can synchronize with the container transport device by a mechanism (or control) and transport the label in synchronization with the movement of the container.

In another preferred aspect, the label transport device and the container transport device can be driven independently of each other, and the label transport device generates a movement speed difference with the container transport device, The circumferential position of the fitted label with respect to the container is adjusted.

In another preferable aspect, the apparatus further includes a shrink device that heat-shrinks the label fitted to the container and closely contacts the container, and the label transport device heats the label by the shrink device. The label is held immediately before or immediately after the start of heating.

In another preferred aspect, the container includes a plurality of pot portions that are continuous and integrated in the transport direction, and the label transport device is a direction perpendicular to the transport direction in the cylindrical label. Hold the sides.

In another preferred aspect, the container transport device sucks and holds the top surface of the container.

According to the present invention, since the side of the cylindrical label is conveyed by the label conveying device, the cylindrical label is prevented from dropping, and the label fitted from below is held at a desired height position. it can.

In this description, specific shapes, materials, numerical values, directions, and the like are examples for facilitating the understanding of the present invention, and can be appropriately changed according to the application, purpose, specification, and the like. In addition, when a plurality of embodiments and modifications are included in the following, it is assumed from the beginning that these characteristic portions are used in appropriate combinations.

The label fitting system 10 of this embodiment is an apparatus for mounting a heat-shrinkable cylindrical label on the outer periphery of a pot portion of a container. In the following, an example will be described in which a 4-pot pack, which is a container that integrally includes four containers of 2 columns × 2 rows each containing contents such as yogurt, is transported and label-fitted. The technology of the form is not limited to this.
For example, the present invention may be applied to a 2-pot pack integrally including two containers of 2 columns × 1 row, a 6-pot pack integrally including 6 containers of 2 columns × 3 rows, or one The present invention can also be applied to the case where the labels are fitted while the containers separated one by one are continuously conveyed in one or more rows.

FIG. 1 is a front view showing an overall configuration of a label fitting system according to an embodiment of the present invention. FIG. 2 is a plan view of the label fitting system 10 of FIG. 1 as viewed from above. Further, in FIG. 3, (a) is a 4-pot pack, (b) is a 2-pot pack, and (c) is a plan view and a side view of a 6-pot pack.

As shown in FIGS. 1 and 2, the label covering system 10 includes a first container transport device 12, a second container transport device 14, a third container transport device 16, in order along the container transport direction indicated by the arrow A. And a fourth container transfer device 18. Among these, the 3rd container conveyance apparatus 16 respond | corresponds to the container conveyance apparatus described in the claim. Further, the label covering system 10 includes a label tunneling unit 20 installed along the third container transport device 16, a label transport device 19, and a heat tunnel (on the downstream side of the fourth container transport device 18). (Not shown). The heat tunnel functions as a shrink device that heat-shrinks the label L fitted to the container C and closely contacts the container C.

1st container conveyance apparatus 12 is an apparatus which conveys in order to introduce container pack CP4 which consists of 4 pot packs shown to Fig.3 (a) in the label fitting system 10. FIG. The first container transporting device 12 has an endless conveyor belt 13 that circulates and each container pack CP4 is transported linearly in the direction of arrow A while being placed on the conveyor belt 13. .

Further, the fourth container transport device 18 has a function of guiding the container pack CP4 with the label fitted on the outer periphery of the pot portion to the heat tunnel, and is configured in the same manner as the first container transport device 12.

As shown in FIG. 3A, the container pack CP4 integrally includes four containers C of 2 columns × 2 rows. Each container C includes a pot portion P that is recessed so as to accommodate contents such as yogurt, a flange portion F that is formed to protrude laterally at the periphery of the upper opening of the pot portion P, and a pot portion P. And a sheet-like lid S that seals the upper opening. These four containers C are integrally connected at the edge portion of the flange portion F having a substantially square outer contour.

The pot part P of each container C is formed in a substantially rectangular shape with the upper opening rounded at the corners. Moreover, the side wall of the pot part P is formed in the external shape which makes a taper shape toward the bottom part of a lower end from upper opening. Further, in the container pack CP4 integrally including four containers C, the pitch between the pot portions P of two containers C adjacent to each other in the container transport direction A is a predetermined pitch PP defined by a molding die of a molding machine to be described later. Is formed. Furthermore, a substantially rectangular through hole is formed in the central portion of the container pack CP4 surrounded by the flange portions F of the four containers C. Furthermore, a product name (not shown) is written on the lid S that seals the upper opening of each container C. In addition, the shallow fracture | rupture facilitation groove | channel for making it easy to fracture-separate into the container C one by one may be formed in the connection part of flange parts F.

An example of a method for manufacturing the container pack CP4 is as follows. First, a resin flat plate is supplied to a molding machine of a manufacturing apparatus. The molding machine includes a male mold formed by aligning convex portions for forming pot portions and a female mold formed by aligning concave portions forming an inner surface corresponding to the outer peripheral surface of each pot portion. The resin flat plate is sandwiched by the mold. Thereby, the recessed part equivalent to the pot part P of each container C is formed. In such a pot portion molding operation, a container intermediate body in which a large number of pot portions P are molded at a predetermined pitch PP by repeatedly executing a process of intermittently supplying a resin flat plate and closing and opening the mold. Is formed.

The container intermediate fed from the molding machine is then supplied to the filling machine. In this filling machine, contents such as yogurt are poured and filled from the upper opening into each pot portion P of the container intermediate. Then, the upper opening of the pot part P is sealed by heat-sealing the sheet-like lid S to the flange part F on the upper surface of the container intermediate. And the container pack continuous body with which several container pack CP4 was connected by the flange part F is sent out from a filling machine.

Thereafter, the container pack continuum is divided into container packs CP4 integrally including a predetermined number of containers C. In the present embodiment, as described above, each container pack CP4 is manufactured by being divided so as to integrally include four containers C of 2 columns × 2 rows. Thereafter, each container pack CP4 is supplied onto the conveyor belt 13 of the first container transport device 12 and transported to the second container transport device 14.

1 and 2 again, each container pack CP4 transported by the first container transport device 12 from the manufacturing apparatus is once accumulated in front of the second container transport device 14 in the container storage unit γ. Then, each container pack CP4 is third in a state where the second container transport device 14 pitches the transport pitch between the container packs CP4 to the predetermined pitch PP between the pot portions P included in the container pack CP4. It is transported to the container transport device 16.

Specifically, the second container transport device 14 includes a plurality of moving claws 21 that move along the container transport direction A on both sides of a linear container transport path 22 continuous with the first container transport device 12 (see FIG. 2). The plurality of moving claws 21 circulate and move on both sides of the container conveyance path 22 while drawing a movement track in a substantially track shape (a shape in which each end of two arcs is connected by two straight lines, the same applies hereinafter). It is configured. The drive mechanism of the moving claw 21 that moves linearly along the container transport path 22 having a straight belt shape can have the same configuration on both sides of the container transport path 22.

Each moving claw 21 is fitted between a support upper surface that is in contact with and suspended from the lower surface of the flange portion F of each container C that constitutes each container pack CP4, and the pot portion P of each container C, and is in the transport direction A. And the tip outer peripheral surface which contacts the outer periphery of two pot parts P adjacent to each other. In the present embodiment, it is preferable that the distal outer peripheral surface of the moving claw 21 is formed in a semicircular shape. By being formed in such a shape, when entering the space between the two adjacent container packs CP4 in which the space between the pot portions P is narrowed in the container storage portion γ, it smoothly enters while widening the space between the pot portions P. The conveyance pitch of the container pack CP4 can be pitched to a predetermined pitch PP.

Each container pack CP4 transported at a predetermined pitch PP by the second container transport device 14 is delivered to the third container transport device 16. The third container transport device 16 includes an endless conveyor belt 34 having a lower surface that moves linearly along the container transport direction A. When the conveyor belt 34 is driven to rotate at a constant speed, the conveyor belt 34 conveys each container pack CP4 pitched to a predetermined pitch PP by the second container conveying device 14 while adsorbing the top surface while maintaining the state. It is a conveyor belt.

The conveyor belt 34 has a large number of through holes (not shown). In addition, a suction box 36 is disposed inside the conveyor belt 34 having a loop shape so as to be adjacent to the lower surface of the conveyor belt 34. An elongated hole 38 extending along the container transport direction A is formed in the lower wall portion of the suction box 36. The suction box 36 is connected to a suction source (not shown) such as a pump. As a result, the conveyor belt 34 of the third container transport device 16 causes the top surface of the container pack CP4 transported by the second container transport device 14 (that is, the upper surface of the container pack CP4 sealed with the lid S) to be the lower surface of the belt. The container pack CP4 can be transported in a suspended state. At this time, the pitch between the container packs CP4 pitched by the second container transport device 14 is suspended and transported while being maintained.

Next, the label fitting unit 20 in the label fitting system 10 will be described. As shown in FIG. 1, the label fitting unit 20 is installed below the third container transport device 16 that suspends and transports the container pack CP4. As shown in FIG. 2, when the space in which the operator OP can work is the front of the label fitting system 10 and the back side sandwiching the third container transport device 16 is the rear, the label fitting unit 20 is The front portion is installed at a position where it overlaps the third container transport device 16.

The label fitting unit 20 includes a large number of mandrel heads 40 for fitting a cylindrical label L around the outer periphery of the pot portion P of each container pack CP4 suspended and conveyed by the third container conveying device 16, and each mandrel head. And a mandrel moving device 42 that circulates 40 along a substantially track-like movement trajectory.

The mandrel moving device 42 includes a driving pulley 44 and a driven pulley 46 that are provided at predetermined intervals, and an endless belt 48 that is stretched around the

pulleys

44 and 46. The drive pulley 44 is configured to be rotationally driven by a motor 49. The many mandrel heads 40 are attached to the outer peripheral surface of the belt 48 at a predetermined pitch. Thus, when the drive pulley 44 is driven to rotate by the motor 49, the belt 48 rotates in the direction of the arrow. As a result, a large number of mandrel heads 40 attached to the belt 48 circulate along a track-like or loop-like circulation path. That is, the mandrel head 40 moves in the straight section 47 in the front portion of the label fitting unit 20. While the movement path of the straight section 47 of the mandrel head 40 is located directly below the third container transport device 16, this translates in synchronization with the container pack CP 4 suspended and transported by the third container transport device 16. The label can be fitted on the outer periphery of the pot portion P of each container C at the label fitting position β.

Further, the label fitting unit 20 is provided with a label forming unit 50. The label forming unit 50 cuts a long label base material into a predetermined length to form a cylindrical label L, and the label L is opened and fitted to the outer periphery of the mandrel of each mandrel head 40. Have the function of handing over.

In the present embodiment, the label is transferred to the mandrel head 40 at the label supply position α on the arcuate movement trajectory before each mandrel head 40 goes around the driven pulley 46 and enters the straight section 47. In addition, a label forming unit 50 is installed. In this way, in the region where each mandrel head 40 moves in an arc shape, a gap is formed relatively large between each mandrel head 40, so that the operation of supplying labels to each mandrel head 40 is reliably performed without interfering with each other. There is an advantage that you can. However, the present invention is not limited to this, and the label forming unit 50 may be installed in another area of the label fitting unit 20 (for example, a rear area of the label fitting unit 20 or the like).

As described above, in this embodiment, the label forming unit 50 forms the label at the position deviated from the container transport path by the third container transport device 16 when the label fitting system 10 is viewed from above, and the label to the mandrel head 40. It is installed so that it can be delivered. As a result, even if the contents stored in the container C of the container pack CP4 spill out due to some trouble at the label fitting position β, there is no cutting unit or the like constituting the label forming unit 50 underneath, so label formation The label supply operation by the unit 50 can be continued without stopping. Therefore, the operation rate of the label covering system 10 is increased, and the productivity can be improved.

The circulation path of the mandrel moving device 42 that circulates and moves a large number of mandrel heads 40 extends from the position overlapping the label fitting position β in the linear container conveyance path in the third container conveyance device 16 to the rear side of the container conveyance path. It is formed as a path that goes around and returns to the label fitting position β through the label supply position α. Thus, since the circulation path of the mandrel head 40 is installed only on the back side of the label fitting system 10, the front side of the label fitting position β can be used as a work space for the operator OP, and workability is improved. Has the advantage of improving.

Furthermore, the label fitting system 10 in the present embodiment is a manufacturing apparatus that performs a series of steps of container molding, content filling, sealing with a lid, and dividing into one or a predetermined number of container packs. It is possible to attach a label with a product name or the like to the outer periphery of the pot portion of each container of the container pack.

FIG. 4 is a front view of the label forming unit 50 provided in the label fitting unit 20, and FIG. 5 is a side view of the label forming unit 50. 4 and 5, the label base material LM and the label L cut and formed from the label base material LM are indicated by a two-dot chain line.

As shown in FIG. 4 and FIG. 5, the label forming unit 50 separates the individual labels L from the label base material LM in a state where the cylindrical labels L are continuously connected and folded into a sheet shape. By sequentially discharging L to the label supply position α, it is delivered to the mandrel M of the mandrel head 40 which is sequentially transferred by the mandrel moving device 42.

The label forming unit 50 includes, in order from the top, a mark sensor 51, an inner guide 52, a pitch feed roller pair 53, a cutting unit 54, a label shaping guide member 55, a pair of

shot rollers

57a and 57b, and a transfer unit 58.

The mark sensor 51 detects a cut mark formed by printing or the like on the label substrate LM. Based on a mark detection signal output from the mark sensor 51, operations of a pitch feed roller pair 53, a cutting unit 54, and the like, which will be described later, are controlled.

The inner guide 52 is provided below the mark sensor 51, and is arranged inside the cylindrical label substrate LM that is continuously conveyed in a connected state. The inner guide 52 functions to release the close contact state of the label base material LM and guide the label base material LM from entering the pitch feed roller pair 53 along the vertical direction.

The pitch feed roller pair 53 is composed of a roller pair of a drive roller 53a and a driven roller 53b that intermittently feed the label base material LM toward the cutting position by a predetermined pitch. The drive roller 53a is rotationally driven by a motor (not shown) such as a servo motor or a stepping motor. Based on the mark detection signal from the mark sensor 51, this motor is intermittently driven and controlled so that the label base material LM is sent downward by a predetermined cut length from between the

rollers

53a and 53b of the pitch feed roller pair 53. Is done.

The cutting unit 54 is a cutting device that includes a fixed blade 54a and a movable blade 54b that form individual labels L by sequentially cutting the label base material LM fed downward by a predetermined length from the pitch feed roller pair 53. The movable blade 54b is reciprocally driven by a motor (not shown) such as a servo motor or a stepping motor, for example, and based on the mark detection signal from the mark sensor 51, the feeding operation of the label base material LM by the pitch feed roller pair 53 is temporarily stopped. During operation, the label L is controlled to be separated from the label base material LM. The cutting unit 54 may be constituted by a fixed blade and a rotary movable blade.

The label shaping guide member 55 opens in a predetermined state by fitting the label base material LM sent out by the pitch feed roller pair 53, and transports the label L cut from the label base material LM to the transfer unit 58. It functions as a guide member when conveyed downward by the action.

The label shaping guide member 55 has a label opening portion 55a having a tapered wedge shape on the upper end side, and a label shaping portion 55b having a circular cross section continuously provided below the label opening portion 55a. The label base material LM fitted on the upper end of the label opening 55a is separated into individual labels L, and then gradually opened by being transferred to the lower side of the label opening, whereby the label shaping unit The opening is shaped into a cylindrical shape by being fitted to 55b. A pair of

shot rollers

57a and 57b are rotatably attached to the lower end portion of the label shaping portion 55b of the label shaping guide member 55.

The transfer unit 58 is placed in the label opening 55a of the label shaping guide member 55, and the label L separated from the label base material LM by the cutting unit 54 is sandwiched between the label opening 55a and the label shaping. It is composed of

feed belt units

58a and 58b which are transferred to the section 55b. Each of the

feed belt units

58a and 58b includes a driving pulley 59a, four driven

pulleys

59b, 59c, 59d, and 59e, and a narrow endless feed belt 59f (for example, about several millimeters) spanned between them. Has been. The feed belt 59f is rotationally driven along the axial direction on both sides of the label shaping guide member 55, so that the feed belt 59f can be transferred to the lower end portion of the label shaping guide member 55 while shaping the label L into an open state. Yes.

The pair of

shot rollers

57a and 57b is provided at a position facing the radial direction at the lower end of the label shaping guide member 55. Each of the

shot rollers

57a and 57b is directly connected to a rotation shaft of a motor (not shown). As a result, when each of the

shot rollers

57a and 57b is rotationally driven, the label L fitted on the label shaping guide member 55 is sent downward along the outer peripheral surface of the label shaping portion 55b, and the mandrel of the mandrel head 40 It will be put on M.

Next, the label fitting unit 20 in the present embodiment will be described in more detail with reference to FIGS. FIG. 6 is a view showing only the mandrel head 40 of the label fitting unit 20 as viewed from above. 7 is a cross-sectional view taken along the line GG in FIG.

As shown in FIG. 6, a number of mandrel heads 40 in the label-fitting unit 20 are rotated counterclockwise in a track-like movement path by the belt 48 spanning the drive pulley 44 and the driven pulley 46 rotating. As described above, it is configured to circulate in the direction (the direction of arrow J).

In the mandrel head 40 according to the present embodiment, the container pack CP4 transported by the first, second, and third

container transport devices

12, 14, 16 described above has containers C in two rows in a direction perpendicular to the container transport direction A. Corresponding to being conveyed side by side, two mandrels M arranged in parallel are provided. When such a mandrel head 40 moves in the straight section 47 of the mandrel moving device 42, the six mandrel heads 40 including the 12 mandrels M are moved in a group in a state where they are aligned at a predetermined pitch PP. It is configured. The predetermined pitch PP is the pot pitch between the pot portions P of the container C integrally included in the container pack CP4, and the two adjacent pot portions P of each container pack CP4 pitched by the second container transport device 14. It is equivalent to the conveyance pitch PP. In the present embodiment, the six mandrel heads 40 aligned in this way are synchronously conveyed by the third container conveying device 16 above the linear mandrel head 47 while moving in a group that is aligned at a predetermined pitch PP. A cylindrical label L pushed up from the mandrel M is fitted from below into each pot portion P of the container pack CP4.

Each mandrel head 40 is attached to the belt 48 at the predetermined pitch PP on the inner peripheral side of the loop-shaped circulation path. However, a gap 41 is formed between the six mandrel heads 40 forming a group in the straight section 47 on the upstream side and the downstream side in the movement direction between the mandrel heads 40 forming another group. The gap 41 is formed larger than the gap between the six mandrel heads 40 forming a group. By providing such a gap 41, the mandrel moving device 42 is used as it is even when it is necessary to replace the mandrel head 40 in order to cope with label fitting of a container pack of another shape and size. It becomes possible.

As shown in FIG. 7, the two mandrels M included in the mandrel head 40 have a gap between the bottoms of the two pot portions P in which the container packs CP <b> 4 lined up and conveyed by the third container conveying device 16 are arranged. The label fitting operation is performed while translationally moving in a non-contact state while facing each other (for example, about several mm to 10 mm). During the label fitting operation, neither the container pack CP4 nor the mandrel M moves in a straight line in the horizontal direction without moving up and down. Therefore, even when the container conveyance speed is increased, the label fitting operation to each pot portion P of the container pack CP4 can be stably performed. Further, since the label covering operation is performed while the upper end of the mandrel M is not in contact with the bottom of the pot portion P, the pot portion P of the container C included in the container pack CP4 is not damaged.

Further, in the label fitting unit 20 in the present embodiment, a configuration is adopted in which six mandrel heads 40 including twelve mandrels M are moved in a straight section 47 in a group arranged with a predetermined pitch PP. As described above, the six mandrel heads 40 including the 12 mandrels M that are the least common multiple of the two pots, the four pots, and the six pots are configured to move in one group. In addition to the pack CP4, two-pot pack CP2 (see FIG. 3 (b)) in which two containers C are integrally connected in two columns and one row via the flange portion F, and six containers C are disposed via the flange portion F. Thus, the 6-pot pack CP6 (see FIG. 3 (c)) integrally connected in 2 columns × 3 rows can be handled without changing parts (or changing models).

More specifically, in the case of the two-pot pack CP2, six two-pot packs CP2 including a total of twelve containers C are pitched to a predetermined pitch PP by the second container transport device 14, and then transferred to the third container transport device 16. It is delivered and suspended and conveyed to the label fitting position β. In the case of the 4-pot pack CP4, three 4-pot packs CP4 including a total of 12 containers C are pitched to a predetermined pitch PP by the second container transport device 14, and then delivered to the third container transport device 16. It is suspended and conveyed to the label fitting position β. In the case of the 6-pot pack CP6, two 6-pot packs CP6 including a total of 12 containers C are pitched to a predetermined pitch PP by the second container transport device 14, and then delivered to the third container transport device 16. It is suspended and conveyed to the label fitting position β. As described above, in any of the 2-pot pack CP2, the 4-pot pack CP4, and the 6-pot pack CP6, it is possible to perform the label fitting by the label fitting unit 20 in the present embodiment. Therefore, the versatility of the label fitting system 10 can be improved and the equipment cost can be reduced.

Note that a gap 41 is formed before and after the six mandrel heads 40 forming the group in the conveyance direction, and a gap corresponding to the gap is formed between the container packs conveyed by the third container conveyance device 16. For example, when the container pack is transferred from the second container transport device 14 to the third container transport device 16, the transport speed of the second container transport device 14 (that is, the moving claw 21 by the motor 30 is moved). Control such as decelerating may be performed.

However, if only a container pack integrally including a specific number of containers C such as a 4-pot pack is considered, it is not necessary to provide the gap 41 as described above, and all the mandrel heads 40 have an equal pitch corresponding to a predetermined pitch. It may be attached to the belt 48. Also in this case, the two-pot pack CP2, the 4-pot pack CP4, and the 6-pot pack CP6 can be used in the same manner as described above.

Next, the mandrel moving device 42 of the label fitting unit 20 will be described in detail with reference to FIG. The two mandrels M of the mandrel head 40 are supported in a state where each lower end portion stands on a metal base plate 60, for example. A bracket 62 is fixed to the inner peripheral end of the base plate 60 by fixing means such as bolts. The bracket 62 is attached to the belt 48 by a fixing means such as a bolt and a nut via an outer peripheral side attachment member 64. Further, an inner peripheral side mounting member 66 is disposed inside the belt 48, and the mandrel head 40 is, for example, a bolt with the belt 48 sandwiched between the outer peripheral side mounting member 64 and the inner peripheral side mounting member 66. And it is being fixed to the belt 48 by fixing means, such as a nut. In this way, the mandrel head 40 is attached to the belt 48 in a cantilever state.

Two rollers 68 are rotatably attached to the inner peripheral side attachment member 66 at positions separated by a predetermined distance in the vertical direction. Of these rollers 68, the upper roller 68 is in contact with the lower surface of the rail member 70 fixed at a predetermined position in the mandrel moving device 42. Thus, the weight of the mandrel head 40 that circulates together with the belt 48 in a cantilever state is supported by the roller 68 and the rail member 70.

As described above, the belt 48 is stretched over the drive pulley 44 and the driven pulley 46, and circulates when the drive pulley 44 is rotationally driven by a motor 49 (see FIG. 2). The

pulleys

44 and 46 are rotatably supported by shafts 45 erected on the mount 43 of the mandrel moving device 42. In FIG. 7, only the driven pulley 46 and the shaft 45 that supports it are shown.

The mandrel moving device 42 is provided with an upper cover 80 having a U-shaped cross section. The upper cover 80 is fixed to a frame 72 fixed to the upper end of the shaft 45 erected on the mount 43 by a fixing means such as a screw. The front wall portion 80 a and the rear wall portion 80 b of the upper cover 80 hang from the upper side to the outer peripheral side of the bracket 62 of the mandrel head 40, and each lower end portion extends to a position close to the upper surface of the base plate 60.

On the other hand, the gantry 43 is provided with a front lower cover 82a and a rear lower cover 82b. The front lower cover 82a and the rear lower cover 82b extend upward in a gap formed at a lower portion between the bracket 62 and the outer peripheral mounting member 64 of the mandrel head 40, and upper ends thereof are front and rear of the upper cover 80. It is located above each lower end part of

wall part

80a, 80b.

A fixing member 74 having a L-shaped cross section or side surface is attached to the top plate portion of the upper cover 80 in front of and behind the mandrel moving device 42, respectively. The first cam plate 76 and the second cam plate 78 are fixed to the front portion of the mandrel moving device 42 by a fixing member 74. The first cam plate 76 constitutes a first cam mechanism together with a first cam follower 94 of a mandrel head described later, and the second cam plate 78 constitutes a second cam mechanism together with a second cam follower 96 of a mandrel head 40 described later.

On the other hand, a support plate 77 is fixed to the rear part of the mandrel moving device 42 by a fixing member 74. The upper surface of the support plate 77 extends in the horizontal direction, and the first cam follower 94 of the mandrel head 40 is in contact with the upper surface. Thus, the weight of the constituent members of the mandrel M included in the mandrel head 40 (that is, the label delivery guide, the push-up plate, the first and second connecting members, etc.) is supported.

In the above description, an example in which the belt 48 is used as a moving member that circulates the mandrel head 40 has been described. However, the present invention is not limited to this. For example, the mandrel head 40 may be connected to the chain as a configuration in which a plurality of chains are circulated and moved by a plurality of sprockets.

In the above description, the example in which the mandrel head 40 circulates in a cantilever state has been described. However, a wheel is attached to the lower surface of the base plate 60 of the mandrel head 40 and the wheel is mounted on a rail fixed to the gantry 43. The mandrel head may be configured to circulate and move. In this case, the mandrel head can be supported more stably.

Subsequently, the configuration and operation of the mandrel head 40 will be described in more detail with reference to FIGS. 8A is a front view including a partial cross section of the mandrel head 40, FIG. 8B is a cross-sectional view taken along line HH in FIG. 8A, and FIG. It is II sectional drawing in a).

As shown in FIG. 8A, the mandrel head 40 includes two mandrels M, a base plate 60 that supports each lower end of the mandrel M, and an inner peripheral end of the base plate 60 (of FIG. 8A). A bracket 62 fixed to the right side) and extending upward in parallel with the mandrel M. The mandrels M are erected on the base plate 60 at a pitch equal to two pot portions P arranged in a direction orthogonal to the container transport direction A (see FIGS. 1 and 2).

The base plate 60 of the mandrel head 40 is preferably made of a metal plate that is lightweight and has rust prevention properties. As a specific example, for example, an aluminum plate can be used for the base plate 60. However, the present invention is not limited to this, and a resin flat plate that is lightweight and has rust prevention properties may be used as the base plate 60.

Each mandrel M has a mandrel shaft 84 whose lower end is fixed to the base plate 60 and extends upward, and a label delivery packaged so as to be movable in the shaft axial direction (vertical direction in the present embodiment) around the mandrel shaft 84. A guide 86 and a push-up plate (push-up member) 88 are provided so as to be movable in the shaft axis direction around the label delivery guide 86.

The mandrel shaft 84 is formed of, for example, a resin rod-shaped member. In the present embodiment, the upper end portion of the mandrel shaft 84 is formed in a substantially square frustum shape. By having such a tapered upper end portion 84a, it is possible to easily receive the label L supplied downward from the label forming unit 50 in the opened state.

Further, the mandrel M has a label holding part (film holding part) 85 below the upper end part 84a of the mandrel shaft 84. The label holding portion 85 is a portion where the label L fitted on the mandrel M is held on the outer peripheral surface of the mandrel M while the mandrel head 40 moves from the label supply position α to the label fitting position β. The label holding unit 85 is located above the label lifting plate 88 in the retracted position.

The mandrel shaft 84 has an intermediate shaft portion 84b that extends downward from the upper end portion 84a. As shown in FIG. 8B, the intermediate shaft portion 84b of the mandrel shaft 84 has a substantially square cross section, and guide grooves 98 made of, for example, V-shaped notches at the four corners along the shaft axial direction. Is formed.

In the guide groove 98 of the intermediate shaft portion 84b of the mandrel shaft 84, a guide bar 86a forming a part of the label delivery guide 86 is fitted. The guide bar 86a of the label delivery guide 86 has a fan-shaped cross section with a substantially right central angle, and the outer surface forming an arc shape forms a part of the surface of the label holding portion 85. Further, the outer surface exposed to the outer periphery of the intermediate shaft portion 84b of the mandrel shaft 84 also constitutes a part of the surface of the label holding portion.

Further, in the intermediate shaft portion 84b of the mandrel shaft 84, four engagement grooves 87 are formed to extend along the shaft axial direction at the center position of each side portion of the substantially square shape. A piece 89a of a push-up plate 88, which will be described later, is fitted in the engagement groove 87 so as to be movable up and down.

As shown in FIG. 8C, the lower shaft portion 84c continuous with the intermediate shaft portion 84b in the mandrel shaft 84 is formed as a round bar shaft portion having a circular cross section. The guide groove 98 and the engagement groove 87 are formed to extend from the intermediate shaft portion 84b of the mandrel shaft 84 to the upper end portion 84a, but are not formed in the lower shaft portion 84c.

The label delivery guide 86 of the mandrel M is composed of a cylindrical member made of the same resin material as the mandrel shaft 84. As shown in FIGS. 8A and 8C, the lower portion 86b of the label delivery guide 86 has a substantially square outer contour with rounded corners, similar to the label holding portion 85 of the mandrel M. Further, the lower portion 86b of the label delivery guide 86 has a cylindrical shape in which a circular cavity is formed. On the other hand, four guide bars 86 a corresponding to the guide grooves 98 of the mandrel shaft 84 are formed on the upper portion of the label delivery guide 86. These guide bars 86a are respectively arranged in the guide groove 98 of the mandrel shaft 84 so as to be movable up and down. It is preferable that the arc-shaped outer surface of the guide bar 86a is formed with almost no step from the outer peripheral surface of the intermediate shaft portion 84b of the mandrel shaft 84. By forming in this way, it is possible to smoothly receive and send the label L about the mandrel M without being caught.

As shown in FIGS. 8B and 8C, the push-up plate 88 of the mandrel M is a flat plate member made of, for example, resin in which two through holes 89 into which the two mandrels M can be inserted are formed. These through holes 89 are formed in a substantially square shape that is slightly larger than the outer contour of the label holding portion 85 including the intermediate shaft portion 84 b of the mandrel shaft 84 and the guide bar 86 a of the label delivery guide 86. Four pieces 89 a that protrude toward the center of the through hole 89 are formed at the center of each side of the periphery of the through hole 89. These pieces 89a are arranged so as to be vertically movable while engaging in an engagement groove 87 formed in the intermediate shaft portion 84b of the mandrel shaft 84.

The label delivery guides 86 of the two mandrels M included in the mandrel head 40 are respectively fixed to, for example, a resin coupling plate 92a at each lower end portion. One end of the connecting plate 92a is fixed to the first connecting member 92b by a fixing means such as a bolt. On the base plate 60, two guide members 90 are erected in parallel with the mandrel M. A stopper 91 is fixed to the upper end of each guide member 90. Here, it is preferable that the guide member 90 is comprised by the metal round bar member which has rust prevention property. Specifically, for example, a round bar made of stainless steel can be suitably used as the guide member 90.

The first connecting member 92b is slidably supported on the guide member 90 through a resin bush 93, for example. A first cam follower 94 is rotatably attached to the side portion of the first connecting member 92b. The first cam follower 94 is in contact with the first cam plate 76 of the mandrel moving device 42. The first cam follower 94 and the first cam plate 76 constitute a first cam mechanism that moves the label delivery guide 86 of each mandrel M up and down.

Further, the push-up plate 88 of the mandrel head 40 is fixed to the second connecting member 95 at one end by a fixing means such as a bolt. Similar to the first connection member 92b, the second connection member 95 is slidably supported by the guide member 90 via a resin bush 93, for example. A second cam follower 96 is rotatably attached to the side portion of the second connecting member 95. The second cam follower 96 is in contact with the second cam plate 78 of the mandrel moving device 42. The second cam follower 96 and the second cam plate 78 constitute a second cam mechanism that moves the push-up plate 88 of the mandrel head 40 up and down.

FIG. 9A is a front view showing the state of the mandrel head 40 at the label supply position α, and FIG. 9B is a front view showing the state of the mandrel head 40 at the label fitting position β.

As shown in FIG. 9A, when the mandrel head 40 passes the label supply position α by the mandrel moving device 42, the cylindrical label is supplied from the label forming unit 50 disposed above in an open state. . At this time, in each mandrel M of the mandrel head 40, the label delivery guide 86 is in a label receiving position (film receiving position) lowered with respect to the mandrel shaft 84. In this state, the guide bar 86 a of the label delivery guide 86 is located below the tapered upper end portion 84 a of the mandrel shaft 84 and is accommodated in the guide groove 98. Therefore, the mandrel head 40 can smoothly and reliably receive the cylindrical label L on the outer periphery of each mandrel M through the tapered upper end portion 84a.

On the other hand, as shown in FIG. 9B, at the label fitting position β, the label delivery guide 86 is moved up to a predetermined height by driving the first cam follower 94 and the first cam plate 76, and the label delivery position ( Film delivery position). At this label delivery position, each upper end portion of the guide bar 86a of the label delivery guide 86 protrudes around the tapered upper end portion 84a of the mandrel shaft 84, and is substantially equivalent to the outer peripheral shape of the pot portion P of the container C. The label L can be sent with the label L opened.

In this state, by driving the second cam follower 96 and the second cam plate 78, the push-up plate 88 moves upward from the retracted position shown in FIG. 9A to the label push-up position shown in FIG. 9B. As a result, the piece 89 a of the push-up plate 88 moves upward along the engagement groove 87 of the intermediate shaft portion 84 b of the mandrel shaft 84. Then, the label L fitted to the label holding portion 85 of the mandrel shaft 84 is lifted with the lower end edge of the label 89 a coming into contact with the one end 89a of the push-up plate 88, and from the mandrel M to the outer periphery of the pot portion P of the container C. It is fitted from below.

Next, with reference to FIG. 10, the label fitting operation by the mandrel head 40 of this embodiment will be described. 10 (a) to 10 (l) are operation explanatory views showing the label fitting operation of the mandrel head 40 over time. 10 (a) to 10 (l), the label covering operation of the mandrel M shifts from the left side to the right side in the figure. In FIG. 10, the movement locus of the center point of the first cam follower 94 is indicated by a two-dot chain line 77, and the movement locus of the center point of the second cam follower 96 is indicated by a two-dot chain line 79. In addition, in FIG. 10, illustration of the 3rd container conveying apparatus 16 which conveys container pack CP4 is abbreviate | omitted.

10 (a) to 10 (c), the mandrel head 40 is moved along the straight section 47 by the mandrel moving device 42. Then, as shown in FIGS. 10D and 10E, when the mandrel head 40 moves to the label fitting position β, the first cam follower 94 is pushed up by the first cam plate 76, and the label delivery guide The guide bar 86 a of 86 becomes a label feeding position protruding around the upper end portion 84 a of the mandrel shaft 84. At this time, the upper end of the guide bar 86a is preferably raised to a position that is slightly higher than the upper end of the mandrel shaft 84 but does not contact the pot portion P of the container C. Thereby, the label L sent out from the mandrel M can be reliably fitted around the pot portion P.

In synchronism with the ascent of the label delivery guide 86, the second cam follower 96 is pushed up by the second cam plate 78 as shown in FIGS. As a result, the push-up plate 88 starts to move upward from the retracted position located below the label holding portion 85 of the mandrel M. Then, the push-up plate 88 moves up to a label push-up position where the upper surface thereof is substantially the same height as the upper end of the guide bar 86a of the label delivery guide 86. As a result, the label L pushed out from the mandrel M by the push-up plate 88 is fitted onto the outer periphery of the pot portion P of the container C from below.

When the label L is fitted on the outer periphery of the pot portion P, as shown in FIGS. 10 (h) to 10 (l), the push-up plate 88 is moved down to the normal retracted position, and the label delivery guide is As shown in FIGS. 10I to 10L, the label is lowered from the label sending position to the label receiving position. Thus, the preparation for receiving the label at the label supply position α is completed.

The container pack CP4 including the container C in which the label L is fitted in the pot part P is continuously transported by the third container transporting device 16 (see FIG. 1). At this time, the label L is transported together with the container pack CP4 by a label transport device 19 described later. In this state, the container pack CP4 is transferred to the fourth container transport device 18 by releasing the suction by the conveyor belt 34 of the third container transport device 16. Thereafter, when the container pack CP4 fitted with the label L passes through a heat tunnel (not shown), the label L is thermally contracted, whereby the mounting of the label L is completed. And container pack CP4 is conveyed by post processes, such as packing.

Next, the label transport device 19 will be described with reference to FIGS. 1, 2, and 11. FIG. 11 is a schematic view of the label transport device 19 as viewed from the transport direction A. A label conveying device 19 is provided between the label fitting position β and the heat tunnel. The label transport device 19 is a device that transports the label L fitted in the pot portion P of the container C together with the container C to the downstream side in the transport direction. That is, the label L is fitted around the outer periphery of each pot portion P by the label fitting unit 20. However, the label L is slightly larger in diameter than the pot portion P before the shrink, and a gap is generated between the pot portion P and the label L. Therefore, when the container C is transported while being suspended by the third container transport device 16, the label L gradually falls due to the influence of gravity, and the relative height position of the label L with respect to the pot portion P is originally There may be deviation from the intended height.

Therefore, in the present embodiment, a label transport device 19 that sucks and holds the label L and transports it together with the container C between the label fitting position β and the heat tunnel is provided. The label transport device 19 includes a pair of conveyor belts 23 disposed on both sides in the width direction (direction substantially orthogonal to the transport direction) with the container pack CP4 interposed therebetween, which is a holding member that sucks and holds the side surface of the label L. . Each conveyor belt 23 is an endless belt that adsorbs the outer surface of the label L fitted in the pot portion P and moves linearly along the container conveying direction A. The conveyor belt 23 is formed with a large number of through holes (not shown). In addition, a suction box 33 is disposed on the inner side of the loop-shaped conveyor belt 23 adjacent to the inner side surface of the conveyor belt 23. An elongated hole extending along the container transport direction A is formed in the side wall of the suction box 33. The suction box 33 is connected to a suction source (not shown) such as a pump. Thereby, the conveyor belt 23 of the label conveying apparatus 19 can adsorb | suck the side surface of the label L fitted to the pot part P to a belt side surface, and can convey it with the container C to a conveyance direction downstream.

The container pack CP4 is transferred to the fourth container transport device 18 by releasing the suction at the downstream end of the third container transport device 16. It is desirable that the label transport device 19 keeps holding the label until the container pack CP4 reaches the heat tunnel even after the container pack CP4 has been transferred to the fourth container transport device 18. By adopting such a configuration, it is possible to reliably prevent the label from dropping until the shrink starts, and to appropriately maintain the height position of the label with respect to the pot portion.

In the heat tunnel, first, steam is injected between two pot portions P arranged in the width direction (position Pm in FIG. 11), in other words, at a place where the conveyor belt 23 of the label conveying device 19 is not present, and the label L Shrink. Then, after the label suction by the label transport device 19 is released, steam is sprayed from both sides of the container pack CP4 in the width direction (position Po in FIG. 11) to completely shrink the label L.

Incidentally, a glue is partially applied to the inner surface of the label L in order to ensure the bonding with the pot portion P during heat shrinkage. As such a paste, for example, an oily paste that exhibits an adhesive force by volatilization of an oily solvent, a heat sensitive paste that exhibits an adhesive force by heating, or the like can be used. It is desirable that the paste is applied to a location that is not adsorbed by the label conveying device 19, for example, a position facing the front surface and the rear surface of the pot portion P. A region E in FIG. 11 shows an example of a paste application portion. By adopting such a configuration, the paste application part E can be brought into close contact with the outer peripheral surface of the pot part at the time of the initial jet of steam (before the release of the label adsorption by the label conveying device 19), and the label L and the pot part P are Glued. As a result, even if the suction by the label conveying device 19 is released, the slippage of the label L from the pot portion P is almost certainly prevented.

In the present embodiment, the label L suction period and the steam injection period by the label conveying device 19 are slightly overlapped, but the label L slippage in the period from the release of the label L suction to the start of steam injection. If the sticking of the label L is released, the steam injection may be started. For example, if the lower end height of the label L is the same as the lower end height of the container C, the container pack CP4 is brought into contact with the fourth container transport device 18 after the transfer to the fourth container transport device 18. , The slippage of the label L is prevented. In such a case, immediately after the container pack CP4 is transferred to the fourth container transport device 18, the label L sucked by the label transport device 19 may be released. In any case, the height position of the label L relative to the pot portion P can be appropriately maintained by sucking and holding the label L during the period in which the container pack CP4 is suspended and conveyed.

By the way, the label transport device 19 of the present embodiment transports the label in synchronization with the container pack CP4. In order to synchronize with the container pack CP4, in this embodiment, the label conveying device 19 and the third container conveying device 16 are driven by a single motor 30. FIG. 12 is a schematic diagram illustrating the drive mechanism of the label transport device 19 and the third container transport device 16. As shown in FIG. 1, the conveyor belt 34 of the third container transport device 16 is stretched between a pair of pulleys 35. The motor 30 rotates the pulley 35 at a predetermined rotational speed. As shown in FIG. 12, the first rotary shaft 25 is fixed to the center of the pulley 35 of the third container transport device 16 and rotates together with the pulley 35. A first transmission pulley 26 is connected to the first rotation shaft 25, and the rotation of the first rotation shaft 25 is transmitted to the second transmission pulley 27 via a transmission belt 27 stretched over the first transmission pulley 26. It is transmitted to the pulley 28. A second rotating shaft 29 is fixed to the center of the second transmission pulley 28. The rotation of the second rotation shaft 29 is converted into rotation in the vertical direction by two pairs of bevel gears 31 connected to the second rotation shaft 29. The conveyor belt 23 of the label conveying device 19 is driven by a pulley 24 that is rotated by this vertical rotational force. Thus, in this embodiment, the 3rd container conveyance apparatus 16 and the label conveyance apparatus 19 are driven with the single motor 30, and both

apparatus

16 and 19 are synchronized by the mechanism. As a result, the conveyance speed difference between the label L and the container C can be reliably prevented, and the position of the label L with respect to the container C can be appropriately maintained.

Note that the synchronization method described here is merely an example, and synchronization may be performed by other methods. For example, the third container transport device 16 and the label transport device 19 may be synchronized by control. That is, after the label transport device 19 and the third container transport device 16 are configured to be driven independently of each other, the

devices

16, 19 are configured so that the transport speed of the label L and the container pack CP4 is the same. The drive mechanism may be controlled. Moreover, the conveyance speed of the label L and the container pack CP4 does not need to be completely the same, and depending on the situation, a slight difference may be caused between the conveyance speeds of the two. For example, when a positional deviation in the circumferential direction of the label L with respect to the pot portion P is recognized, a speed difference is generated between the transport speed of the label L and the container pack CP4, and the positional deviation of the label L is corrected. May be.

In any case, in the present embodiment, the label transport device 19 is provided to hold the label L fitted in the container C and to transport the label L together with the container C. As a result, the label L can be reliably prevented from slipping out of the container C, and the label L can be kept at an appropriate position.

The configuration of the present invention is not limited to the above-described embodiment and its modifications, and various modifications and improvements can be made within the scope of the matters described in the claims of the present application and their equivalents. It is.

For example, the present invention is not limited to the container pack filled with the contents in the above-described embodiment, but includes a state in which the cylindrical film is fitted from the lower side to the body of the container of various shapes including the state where the contents are not filled. It can be widely applied to the film-covered head. Here, the “body body” of the container includes a cap part of the container, and the present invention may be applied when the tubular film is fitted as a so-called cap seal. Further, the conveyor belt 23 (holding member) of the label conveying device 19 may be held by means other than suction as long as the side surface of the label L can be held. For example, the label L may be held using static electricity. As another configuration, the label L may be pressed against the side surface of the container C to prevent the label L from falling.
Moreover, the technique of this embodiment is applicable also when the height of the label L is small compared with the height of the container C, and the label L is mounted | worn only in a part of height direction of the container C. In this case, the label conveyance device 19 may be arranged at a height position corresponding to the mounting height position of the label L with respect to the container C. In order to improve versatility, it is desirable that the height position at which the label conveying device 19 holds the label L can be changed as appropriate according to the type of the label L and the container C to be handled. For example, an adjustment mechanism for changing the height position of the conveyor belt 23 may be provided in the label conveying device 19.
Furthermore, the technology of the present embodiment is such that the height of the label L is larger than the height of the container C, and the label L is fitted with the tip protruding from the bottom surface of the container C. It can also be applied to the case where the label L is heated and shrunk so that the label L is wound from the side surface to the bottom surface of the container C. In this case, the third container transport device 16 is extended into the heat tunnel, and transported in a state where the top surface of each container C is sucked and held suspended. As another configuration, a jig conveyor synchronized with the third container transport device 16 that transports the containers C while adsorbing and suspending the top surface of the containers C is provided so as to overlap the lower side, and a label L is applied to the conveyor. Each fitted container C is transferred, conveyed to the heat tunnel with the center of the bottom surface of each container C held by a jig, and the label L is heated and contracted so that the label L is wound from the side surface to the bottom surface of each container C. It is good also as a structure to mount.
