Description

  The present invention relates to a packaging device having a label underlaying function of packaging a product using a stretch film and pasting a label on a lower surface of a product to be discharged after packaging.

Fresh foods (meat, fish, etc.) and prepared foods such as side dishes and bento boxes that are handled at supermarkets are placed on trays and packed with stretch film along with the trays. A label with information such as name, price, unit price, and barcode is affixed, but information that cannot be printed on the label, such as additive data, is printed on another label, May be affixed to the bottom.
And the packaging apparatus which can perform from the packaging of the goods piled up on the tray to the label sticking to the lower surface of the packaged goods with one machine is already known (for example, refer patent document 1).

In a packaging device having a label underlay function shown in Patent Document 1, a packaged product discharged from a packaging machine is conveyed leftward or rightward along the packaging machine from a discharge position along a packaging machine from the discharge position. A lower labeling machine is disposed below the conveying surface.
Then, a label for affixing is issued in the same direction as the direction of goods transported by the transport conveyor, and the issued label moves on the opening from the opening formed in the transport path of the transport conveyor for transporting the goods ( It is attached to the lower surface of the product to be moved. Here, the reason that the product conveyance direction and the label issuance direction are set in the same direction is to allow labeling to be accurately performed on the product moving (passing) over the opening.

  However, the width of the packaging device (the width in the direction facing the infeed part and the discharge part of the packaging machine) is desired to be as small as possible because of the adjacent equipment after installation. However, when the product conveyance direction and the label issuing direction are the same, the label roll set in the label issuing unit is also set in the same direction as the product conveyance direction. Therefore, when a label roll having a particularly large diameter can be set, the length of the conveyor of the product conveying conveyor becomes long, and as a result, the size in the width direction of the packaging device becomes large (long).

  In addition, as described in Patent Document 1, even if the length of the conveyor for conveying the product is not increased, a space corresponding to the size of the label roll is created above the label roll, As a result, the dimension of the packaging device in the width direction could not be reduced.

JP 2002-308235 A (see FIGS. 1 and 2)

  The present invention has been made in view of the above-described problems of the prior art, and the problem is to reduce the diameter of the label roll of the label issuing unit that prints and issues the label to be attached to the lower surface of the product. And providing a packaging device with a label underlaying function that can reduce the width direction of the packaging device.

In order to solve the above-described problems, the packaging device of the present invention discharges a packaged product discharged from a packaging machine having a packaging function by a stretch film along the packaging machine, and on the lower surface of the product in the discharging process. A packaging device having a label underlaying function for attaching a label, the first transport conveyor for transporting a packaged product discharged from the packaging machine along the front surface of the packaging machine, and the first transport conveyor A label underlaying device arranged in series on the downstream side of the printer, and the label underlaying device receives and conveys products from the first transport conveyor and is used for labeling in the middle of the transport path. A product conveyor having an opening, a label issuing unit that is positioned below the product conveyor and issues a label, and conveys the issued label to the opening of the product conveyor, and passes through the opening. To including the label attachment unit for attaching a label to the lower surface of the product, the label issuing unit is arranged such that a label issuing direction perpendicular to the conveying direction in plan view of the product by the product conveyor, the labeling unit is the label disposed issue port of issuing unit, perpendicular plan view of the conveying direction of the label with respect to the label printing direction, and the conveying direction and the direction of the product conveyor, Ru to face the opening of the product conveyor ( Claim 1).
The product conveying conveyor of the label underlaying apparatus may be either a roller conveyor or a belt conveyor, and an opening, that is, a label applying position is provided in the conveying path of the conveyor.
Further, the label issuing unit of the label underlaying device may be either a label printer that prints and issues predetermined information on a label, or a label issuer that issues a label on which predetermined information is printed.
Further, the orthogonality of the label issuing direction of the label issuing unit and the conveying direction of the product conveying conveyor in plan view includes not only a strictly right-angled crossing but also a crossing state close to a right angle.
In addition, the labeling unit that attaches the label issued from the label issuing unit to the lower surface of the product through the opening of the product transport conveyor is mechanically labeled by a label transport method, air blowing method, pusher, etc. Any method may be used such as pressing and sticking.
With this configuration, even if the diameter of the label roll set in the label issuing unit is large, the outer diameter does not affect the machine length direction of the commodity transport conveyor.

The label underlaying device has a label issuing unit disposed below the product transport conveyor, and the product transport conveyor is configured to be horizontally movable in a direction perpendicular to the product transport direction and toward the front of the device, the label issuing unit has been configured so as to be exposed by the horizontal movement.
With this configuration, when the product transport conveyor is horizontally moved to the front side of the apparatus, the label issuing unit is opened and the label issuing unit is exposed. As a result, it is possible to easily replace the label roll set in the label issuing unit, inspect the equipment, and the like.

In addition, a guide member may be disposed at the end of the first transport conveyor on the downstream side in the transport direction to contact the product to be transported and guide the product toward the opening side of the product transport conveyor. Yes. Then, the guide member is rotated at a slower speed than the conveying speed of the first conveyor, Ru can be assumed that the items to the centering guide in the speed difference.
With this configuration, the product conveyed by the first conveyor can be guided in a fixed direction (opening side) by the guide member, thereby reliably sticking the label to a predetermined location on the lower surface of the product. It becomes possible.

Furthermore, the 2nd conveyance conveyor which accumulates the goods by which the label was stuck on the lower surface of goods is connectedly arranged in the downstream of the goods conveyance conveyor in the said label lowering apparatus. Then, the second transport conveyor, the use state of the substantially horizontal continuous to the conveying surface of the product conveyor to the transport surface, freely switched between a storage state in which the conveying surface is hanging substantially vertically downward.
With this configuration, when packaging the product, the second transport conveyor is placed in a substantially horizontal state in which the transport surface is continuous with the transport surface of the product transport conveyor, so that the products with labels attached thereto can be collected. When the packaging operation is not performed, the second conveyor is folded to make a space for the conveyor, and the installation space can be effectively used.

In addition, an infeed part for supplying products into the packaging machine is provided at the front part of the packaging machine, and in the position adjacent to the infeed part, the transport direction of the product conveyor and the label roll of the label issuing part but but it may also be to place the label Shitabari device to orthogonal.
In that case, since the label lowering apparatus with a small horizontal width can be arranged in parallel with the infeed part, the dimension in the width direction of the entire packaging apparatus can be reduced.

Further, a label transporting conveyor in which the labeling part of the label underlaying device is constituted by a label transporting conveyor, and the label issuing part is arranged so that the label issuing direction by the issuing part is in the same direction as the transporting direction of the product transporting conveyor The label conveying conveyor is arranged so as to cross the plane in the direction of conveyance of the label, and the label conveying conveyor has a substantially horizontal state for receiving the label issued from the label issuing unit, and the received label faces the opening of the commodity conveying conveyor. It is also possible to make the posture changeable and controllable to the inclined state for this purpose (claim 2 ).
In that case, even if the label issuing direction of the label issuing unit and the conveying direction of the label conveying conveyor intersect each other, the posture of the label conveying conveyor is changed to a substantially horizontal state substantially the same surface as the issuing surface of the label issuing unit. Since the label is received, it is possible to reliably deliver the label.
Therefore, since the label issuing unit can be arranged so as to cross the conveyance direction of the product conveyor, the length of the product conveyor can be shortened.
Also, the label Shitabari device but it may also be configured to be movable above the first conveyor. In that case, the maintenance work of the label lowering apparatus can be easily performed.

Since the packaging device of the present invention has the configuration according to claim 1 and the label for underlaying applied to the lower surface of the product is issued in a direction orthogonal to the conveyance direction of the product, the diameter of the label roll itself set in the label issuing unit Since the length of the product conveying conveyor can be shortened without reducing the size, the size in the width direction of the apparatus can be reduced.
In addition, the label roll itself set in the label issuing unit is also set in the direction orthogonal to the product conveyance direction, and the label is issued in the direction orthogonal to the product conveyance direction, so it is easy without reducing the diameter of the label roll. With this structure, it is possible to reduce the dimension in the width direction of the label lowering apparatus.

Further, the configuration of claim 2, be arranged the label issuing unit so that the conveying direction of the label printing direction and the label transport conveyor to plan chiasm (substantially right angle), stabilizing the delivery of labels to be issued It became possible to do. Thereby, in the label conveyance type undercoating device, the label issuing unit can be arranged at a position intersecting with the conveyance direction of the product conveyance conveyor, so that the length of the product conveyance conveyor can be made shorter than that of the conventional device.
Therefore, even when it is incorporated into a packaging device or the like, it can be installed even in an environment where there is not enough room for the product conveyor.

An example of an embodiment of a packaging device according to the present invention will be described with reference to the drawings.
FIG.1 and FIG.2 shows the outline of the packaging apparatus A by the stretch film incorporating the label conveyance type label lowering apparatus B. FIG.
When the packaging device A carries in the product a (the content is stored in the tray in the drawing), it comes with a measurement value, wraps with a stretch film, and issues a label based on the measurement value and data input from the console unit. This is a device known today that automatically performs a series of operations for pasting.
That is, when a product is placed on the infeed unit 7, the product is weighed, and the size of the product (tray) is measured by passing between sensors provided on both sides on the conveyance path start end side. Then, the product a is transported to the position directly above the elevator 8 by the pusher conveyor 7 ', and the product a is mounted on the elevator by the elevator 8 being lifted, and stretched on the upper packaging portion. Pushed up from below, the upper surface of the product is covered with a stretch film. And the peripheral edge part of the stretch film which coat | covered the upper surface of the goods a is folded in the bottom face side of the goods with the right-and-left folding board 9 and the back folding board 10, and also the front side edge part of a film is also goods of a goods by pushing of a discharge pusher. Folded to the bottom side, the ends of the folded film are brought into close contact with each other at the heat seal portion and discharged.
Then, the product name, price, unit price, capacity, expiration date on the top surface of the product a ′ packaged in the process of being discharged by the discharge pusher, based on the weighing at the time of product delivery and data input from the console unit 11 A label L ′ in which items necessary for the customer to select a product are printed by the label printer 12 is pasted by the label pasting machine 13. The label L ′ is affixed by the label affixing machine 13 while the label affixing machine 13 sucks and holds the label L ′ printed and issued by the label printer 12, moves onto the product a ′, and affixes it to the upper surface (surface) of the product. .
The packaged product a ′ to which the label L ′ is affixed is an item that cannot be displayed on the label L ′, for example, a label L that describes items such as a barcode, an additive name, and a place of origin display. It is transported by the first transport conveyor (discharge conveyor) 14 to the label underlaying device B portion to be pasted on the lower surface of '.

  When the weighing of the product a by the weighing unit provided in the infeed unit 7 is stabilized, the upper label L ′ to be pasted on the upper surface of the product and the lower label L to be pasted on the lower surface of the product are printed and issued. Wait for the labeling timing. However, for the label L for underlaying, if the label issuing sensor 45 of the label underlaying apparatus B, which will be described later, is not ON, no label is issued even if the weighing is stable, and the product is placed in the infeed section and weighing is performed. Even if is stabilized, the product is not conveyed to the elevator side, and an error message is displayed on the display unit of the console unit 11. That is, the label L for underlaying is issued when the label issuing sensor 45 of the label underlaying apparatus B is ON and the weighing is stable.

  The first transport conveyor (discharge conveyor) 14 is a conveyor that feeds a product a ′ wrapped in a film to the label lowering apparatus B, and the conveyor is perpendicular to the discharge direction of the product a ′ in the packaging machine. The products a ′ are arranged so as to be crossed so that the product a ′ can be discharged in the left-right direction along the packaging machine. The first transfer conveyor (discharge conveyor) 14 transmits the rotational force of the motor 14a to one of the rollers 14c around which the belt 14b is wound via power transmission means such as a belt or a chain, thereby the belt 14b. Is designed to rotate. The first conveyor 14 is activated when a product is detected by the discharge sensor 37 provided at the front end of the heat seal portion of the packaging machine, and rotates for a predetermined time. The rotation direction of the belt is determined by the installation position of the label lowering apparatus B provided side by side on the first conveyor 14. In this embodiment, it rotates in the right direction.

Hereinafter, the label lowering apparatus B will be described in detail.
FIG. 3 is a plan view showing an outline of the label underlaying device B portion, and is arranged close to the downstream side of the first carry-out conveyor (discharge conveyor) 14 of the packaging device A as described above. On the downstream side in the conveyance direction of the commodity conveyance conveyor 1 in B, a second conveyance conveyor 15 that temporarily stores the commodity a ′ on which the label L has been pasted is disposed.

  The label underlaying device B conveys and affixes the label L issued from the label issuing unit to the lower surface of the product a ′ while conveying the product a ′. A label constituting a label issuing unit 3 for printing and issuing a label L, and a label applying unit for transferring and attaching the label L issued by the label issuing unit 3 to the lower surface position of the product a ′ conveyed by the product conveying conveyor 1 It is comprised with the conveyance conveyor 4. FIG. That is, the label issuing unit 3 is positioned below the conveyance path surface of the commodity conveyance conveyor 1.

The product transport conveyor 1 is composed of roller conveyors in which rollers 1a are arranged in parallel at a predetermined interval. An opening 2 is formed in the middle of the transport path, and a tip along the transport direction of a label transport conveyor 4 described later. The part is configured to face.
As shown in FIGS. 4 and 5, the driving system for rotating the rollers 1a constituting the commodity transport conveyor 1 is such that a driving belt 16 that rotates endlessly on the upper outer peripheral surface of one side end of all the rollers 1a is held in contact. The drive belt 16 is wound around a pulley 18 driven by a motor 17 and rotates endlessly. That is, each roller 1a rotates by contact with the drive belt 16, and the product a 'is conveyed by the rotation of the roller 1a. The commodity conveyor 1 starts rotating at the same time as the first conveyor (discharge conveyor) 14 starts rotating.

  And the opening part 2 is formed in the middle location along the conveyance direction of the said goods conveyance conveyor 1. As shown in FIG. The opening 2 has the length of a plurality of (two in the drawing) rollers 1a 'located in the middle of the plurality (eight in the drawing) of rollers 1a constituting the conveyor 1, and other rollers. Rollers 1a other than the short roller 1a and the supporting plate 19 that supports the end of the short roller 1a 'opposite to the drive belt 16 and the roller 1a that is formed shorter than the length of the la 1a'. The opening 2 is defined by a drive frame 16 and a support frame 19 ′ that supports the opposite end of the drive belt 16. And the label L conveyed by this opening part 2 is prevented from contacting the roller 1a of the goods conveyance conveyor 1 in the upstream position in this opening part 2, and it is made to stick and transfer to the lower surface of goods smoothly. A Soroban ball-like guide roller 38 is attached.

As described above, the product transport conveyor 1 constituted by the roller conveyor is supported so as to be horizontally movable in the front side direction (the lower side direction in FIG. 2) of the packaging device perpendicular to the product transport direction by the rotation of the rollers 1a and 1a '. ing.
The support structure is such that guide frames 39 and 39 ′ having a substantially U-shaped cross section are fixed along both sides of the lower surface in the width direction of the frame of the commodity transport conveyor 1, and the guide frames 39 and 39 ′ accommodate the label issuing unit 3. It is slidably fitted to guide plates 41 and 41 ′ attached to both upper sides of the frame body 40.
A magnet 42 is attached to the outer surface of the support frame 19 ′ of the horizontally movable product transport conveyor 1. When the product transport conveyor 1 is held at the transport position, the magnet 42 is attracted to the member of the packaging device A. The product conveying conveyor 1 is not moved carelessly. Further, a handle 43 is attached to the outer surface of the mounting frame 44 to which the drive mechanism of the product transport conveyor 1 located on the opposite side to the side on which the magnet 42 is attached in the product transport conveyor 1, and the product transport conveyor 1 is moved horizontally. Can be easily performed.

In addition, a product detection sensor 20 for detecting that the product a ′ is supplied onto the product transport conveyor 1 is provided on the inlet side (upstream side) of the product transport conveyor 1. The posture of the label conveyor 4 is switched, that is, the operation starts from the horizontal state to the standing and inclined state, and when a predetermined time elapses from the detection signal of the product detection sensor 20, it is determined that label sticking has been completed, and the state changes from the inclined state to the horizontal state. A timer (not shown) for performing the switching control is activated.
The merchandise detection sensor 20 may be either a transmission type or a reflection type, and is configured to turn on / off an electromagnetic solenoid that switches the posture of the label transport conveyor 4 to be described later with the detection signal.

  At a lower position within the range of the opening 2 of the product transporting conveyor 1, a label transporting conveyor 4 is arranged with its transporting direction in the same direction as the transporting direction of the product transporting conveyor 1. The label issuing unit 3 is disposed in the section so as to cross the direction in which the label L is issued at right angles to the conveying direction of the label conveying conveyor 4.

The label issuing unit 3 prints and issues required data, for example, items such as barcodes, additive names, and origin indications, on the label L based on data input from the console unit 11 of the packaging apparatus A. It consists of '.
As shown in FIG. 4, the label printer 3 'includes a label roll 3a in which a label is detachably attached to a mount, a thermal head 3b, a platen roller 3c, and a mount take-up roller 3d. , A feed roller 3e, a mount roller 3d and a motor 3f for driving and rotating the feed roller 3e, etc., which are well known today, and the required items are printed on a label on the mount by a thermal head 3b and a platen roller 3c. Then, the label after printing is peeled off from the mount by the dispenser 3g at the tip of the platen roller 3c, sent to the issuing port, and delivered to the label conveying conveyor 4 arranged so as to cross the issuing port substantially at right angles. The label roll 3 a is arranged so that the paper drawing direction from the label roll 3 a intersects at right angles to the conveyance direction of the commodity conveyance conveyor 1.

The label conveying conveyor 4 includes a pair of rollers 4a and 4a ′, an endless belt 4b wound around the pair of rollers 4a and 4a ′, and a motor 4c that drives and rotates one of the pair of rollers 4a. The rotation of the motor 4c is transmitted to the roller 4a by belt transmission. A large number of suction holes 4d are formed in the endless belt 4b that rotates endlessly, and a suction force generating means 5 is accommodated in the interior defined by the pair of rollers 4a, 4a ′ and the endless belt 4b. Has been placed.
The suction force generating means 5 is composed of a suction fan and a motor, and is arranged such that suction force is generated on the transport surface (outward side) of the endless belt 4b by the rotation of the suction fan. The suction force generating means 5 is attached to a frame 4e that supports the pair of rollers 4a and 4a 'of the label transport conveyor 4. In the frame 4e, a plurality of (three in the drawing) long holes 27 communicating with the suction force generating means 5 are formed in a plane portion that supports the forward path side of the endless belt 4b. A suction force is generated on the forward path surface of the endless belt 4b.
As a result, the label L issued from the label issuing unit 3 with the adhesive surface facing up is placed on the endless belt 4b, and is sucked and held on the endless belt 4b by the suction force acting on the belt surface.
A label issuing sensor 45 that detects whether or not a label L has been issued on the endless belt 4 b of the label conveying conveyor 4 is installed below the label conveying conveyor 4.

Further, the label conveying conveyor 4 maintains a horizontal state when receiving a label from the label issuing unit 3 and, after receiving the label, conveys and supplies the label L to the opening 2 of the commodity conveying conveyor 1. The posture is switched to the inclined state, and the posture is switched to the initial horizontal state after the label L is attached to the lower surface of the product.
The posture switching control is performed in such a manner that the frame 4e is fixed so that the conveyor 4 as a whole rotates up and down around the axis 21 of one of the rollers 4a and 4a 'which is driven and rotated among the pair of rollers 4a and 4a' in the label conveyor 4. It is attached to be pivotable. An electromagnetic solenoid 22 for raising and lowering the conveyor 4 is connected via a linkage 23 on the outer side (right side in FIGS. 4 and 6) of the axis 4 of the rotation center of the frame 4e.
Accordingly, when a detection signal is output from the commodity detection sensor 20 described above, the electromagnetic solenoid 22 is turned on and the rod 22 'is pulled in, whereby the label transport conveyor 4 is rotated upwardly with the axis 21 as a fulcrum. . Then, when the timer is started from the detection signal output of the commodity detection sensor 20 and a predetermined time has elapsed, the energization to the electromagnetic solenoid 22 in the ON state is turned off, and thereby the weight of the label transport conveyor 4 and the electromagnetic solenoid 22 are built in. The rod 22 'is pushed out by the action of the spring, and the posture of the label transport conveyor 4 is switched from the inclined state to the horizontal state.

Further, the label conveying conveyor 4 is provided with a label presser 6 for pressing the label L sucked and held on the endless belt 4b of the conveyor 4.
As shown in FIGS. 3 and 5, the label retainer 6 is provided with a roller 6b having an outer peripheral surface formed at an acute angle like a Soroban ball on the horizontal end of a frame body 6a having a substantially L-shaped side surface and a substantially U-shaped surface. A plurality of pieces are mounted so as to be freely rotatable. This label presser 6 is pivotally supported by a shaft 24 connecting the frame 4e and the linkage 23 of the label transport conveyor 4 so that the lower end of the vertical portion of the frame 6a is rotatable. A protruding piece 25 is formed to protrude at the end opposite to the side on which 6b is attached (right side in FIG. 5), and in the horizontal state of the label conveying conveyor 4, the engaging piece 26 is attached to the fixing member. The label retainer 6 is configured to be held in contact with and engaged with the endless belt 4b of the label conveying conveyor 4.

Accordingly, when the posture of the label conveyor 4 is switched to the upward inclined state with the axis 21 as a fulcrum by the action of the electromagnetic solenoid 22, the protruding piece 25 of the label presser 6 is separated from the engaging piece 26, and the frame 6a is connected to the shaft 24. The front end side to which the roller 6b is attached rotates about its own weight, and the roller 6b contacts the label L sucked and held on the endless belt 4b of the label conveyor 4. By forming the shape of the roller 6b in the label presser 6 into a Soroban ball having an acute outer peripheral surface, it is difficult to adhere when the label L is pressed, and the label L can be transported smoothly. The roller 6b may be formed into a cylindrical shape without forming a Soroban ball, and the surface thereof may be subjected to an easily peelable surface treatment (for example, Teflon (registered trademark) processing).
In a horizontal state where the label transport conveyor 4 receives the label from the label issuing unit 3, the label transport conveyor 4 maintains a non-contact state separated from the surface of the endless belt 4b of the conveyor 4, and the label transport conveyor 4 receives the label L and tilts upward. When the posture is switched to the state, the belt L is approached and urged so as to press the label L sucked and held on the endless belt 4b.

In the label lowering apparatus B configured as described above, the conveying surface of the first conveying conveyor 14 and the conveying surface of the commodity conveying conveyor 1 are the same height in a normal use state. In order to facilitate the maintenance work (label issuing unit 3, label conveyor 4 etc.), the label lowering device B is supported so as to be movable above the conveying surface of the first conveyor 14. To do.
In the supporting structure, the label under-sticking device B is connected and supported at the front position of the packaging device A by the parallel link mechanism 33, and a gas spring 47 is installed over the parallel link mechanism 33 and the packaging device. Accordingly, the vertical movement of the label lowering device B can be smoothly performed by the action of the gas spring 47.

The label L transported by the operation of the label transport conveyor 4 is such that the product a ′ transported by the product transport conveyor 1 passes through the opening 2 formed in the transport path of the conveyor, thereby lowering the bottom surface of the product. However, if the product a ′ transported by the product transport conveyor 1 always passes through the same position with respect to the opening 2, the position where the label L is pasted can also be fixed.
For that purpose, the movement position of the product a ′ supplied from the first transport conveyor 14 to the product transport conveyor 1 is constant, and between the first transport conveyor 14 and the product transport conveyor 1 and of the transport conveyor 14. A guide member 28 is provided at one end portion in the width direction.

The guide member 28 guides the product a ′ transported by the first transport conveyor 14 toward the side wall 29 that stands on the side of the opening 2 of the product transport conveyor 1, and rotates vertically. It is composed of rollers.
Specifically, as shown in FIGS. 9 and 10, the intermediate roller 30 is arranged in parallel between the downstream end portion in the transport direction of the first transport conveyor 14 and the upstream end portion in the transport direction of the product transport conveyor 1. The intermediate roller 30 is arranged so as to be belted on the roller 14c of the first conveyor 14 and rotated.
A gear 31 is fixed to one end of the intermediate roller 30, and a gear 32 fixed to the lower end of the guide member 28 that is vertically supported by the gear 31 is engaged. Thereby, when the first conveyor 14 is started, the rotation is transmitted as intermediate rollers 30 → gear 31 → gear 32, and the guide member 28 is also rotated. The rotational speed of the guide member 28 is set slower than the rotational speed of the first conveyor 14 (intermediate roller 30) (the outer diameter of the intermediate roller 30> the outer diameter of the guide member 28). As a result, the sheet is moved by the dimension l with respect to the transfer position on the first transfer conveyor 14 and transferred by the product transfer conveyor 1 (see FIG. 10).

  With the above configuration, as shown in FIG. 11, the product a ′ is transported by the first transport conveyor 14 and transferred to the product transport conveyor 1 from the first transport conveyor 14. When contacted, the rotational speed of the guide member 28 is slower than the transport speed of the first transport conveyor 14, so that the product a ′ in contact with the guide member 28 is guided to be wound on the guide member 28, and the product transport conveyor 1 In operation, one side of the product a ′ is conveyed while being in contact with the side wall 29.

  By the action of the guide member 28, the product a ′ is transported on the opening 2 near the side wall 29 in the product transporting conveyor 1, and when passing through the opening 2, the label transporting conveyor 4 faces the opening 2. The label L comes into contact with the lower surface of the product a ′ in contact with the conveyed label L. Then, the label L is sequentially adhered to the product a ′ side by the movement of the product a ′ and the conveyance of the label conveying conveyor 1, and the label L is attached to the lower surface of the product a ′ by passing through the opening 2. (See FIG. 12).

When the label L is affixed to the lower surface of the product by the label lowering device B, the product a ′ is installed in parallel on the downstream side of the product conveying conveyor 1 in the label lowering device B with the conveying direction orthogonal to each other. It is discharged to the second conveyor 15.
The second transport conveyor 15 is configured by foldably connecting a short roller conveyor 15a in which rollers are freely installed and a long roller conveyor 15b in which rollers are provided so as to be freely rotatable. The conveyor 15a holds one side (upstream side) in the transport direction at the same height as the transport surface of the product transport conveyor 1, and the other side (downstream side) is inclined downward to the downstream of the product transport conveyor 1. Attached in parallel along the side edges.
A stopper 46 is provided at the front end of the long roller conveyor 15b in the conveying direction to receive the product a '.

A long roller conveyor 15b is connected to the downstream end of the short roller conveyor 15a, and a stay 34 is rotatably connected to the frame of the connected long roller conveyor 15b. An engagement piece 36 that is engaged with and disengaged from the latch bar 35 fixed to the packaging device A side is attached to the other end of the package (see FIG. 13).
The length of the stay 34 is such that the short roller conveyor 15a and the long roller conveyor 15b are inclined substantially in a straight line when the engaging piece 36 attached to the tip of the stay 34 is engaged with the latch bar 35, Projected forward and supported. Then, when the long roller conveyor 15b is lifted upward and the engagement piece 36 is removed from the latching bar 35, the long roller conveyor 15b is broken at the connecting portion with the short roller conveyor 15a and hangs vertically downward (see FIG. 15). .
Thereby, when the second transport conveyor 15 is not used, the overhang of the long roller conveyor 15b exists as a space compared to the time of use, and the apparatus can be made compact.

The present invention is not limited to the embodiment described above, and the following modifications are possible.
(1) The type of the packaging machine that constitutes the packaging device is not limited. Moreover, the conveyance direction of the 1st conveyance conveyor arrange | positioned at the product discharge part of a packaging machine is determined according to the installation place of an apparatus, and may be either right or left.
