Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings. FIGS. 1 to 4 show an example of a mount (P) with a shrink film for heat shrink packaging that is a product of the present invention. Through the adhesive (2) applied by a certain length (L) and width (W) along the transport center line (front / rear center line / longitudinal center line) (OO) of the mount (1), the mount is provided. Shrink film (PVC, polyethylene, polyvinylidene chloride, polypropylene, polystyrene, polyester, other heat-shrinkable stretch films) (3) (3) bottomless cylindrical shape (1) It is not a tunnel shape, but is affixed and integrated as a sheet-like film having a bottomed bag shape (substantially U-shaped cross section). (4) shows a preheated or folded bottom of the film (3).

The bag-shaped shrink film (3) having such a bottom (4) is in a flat folded state as a product (P) affixed to the mount (1), but is expanded and three-dimensionalized from the entrance. After the product is inserted into the inner space, the product is thermally shrunk, resulting in a completely beautiful packaging.

In this case, the outline shapes of the mount (1) and the shrink film (3) shown in FIGS. 1 and 3 are both simple rectangular shapes (a semi-elliptical shape having a circular arc at the front end). The relative ratio of the size and the pasting position of both change depending on the size and shape of the product. The mount (1) may be provided with a hanging hole (5) for display, a punched window (not shown), and the like. Needless to say, the figure or characters of the product are printed on the front surface and / or the back surface of the mount (1).

5 and 6 schematically show the entire manufacturing apparatus according to the present invention. The substantially rectangular parallelepiped rigid apparatus frame (M) extending in the front-rear direction has a rear side (manufacturing process). From the upstream side) to the front side (also downstream side) of the mount supply unit (A) and the transfer unit (B), the adhesive application unit (C) in the middle of the mount transfer unit (B), and the film supply The part (D), the attachment part (E) of the film (3) to the mount (1) after application of the adhesive, and the discharge part (F) of the finished product (P) are assembled.

Among these main components, first, the mount supply section (A) is disposed at the rear end (upstream end of the manufacturing process) of the apparatus frame (M), from FIGS. 7 and 8 and FIGS. As is obvious, a magazine magazine rack (10) for mounting a fixed unit amount (for example, 100 to 200 sheets) of the mount (1) in a stacked state in a substantially horizontal posture, and the magazine rack (10) The mount (1) that naturally falls sequentially from the bottom of the opening is composed of a mount feed mechanism (11) that feeds the mount (1) one by one to the front where the mount transport section (B) exists.

A mount feeding slit (12) is formed in the front wall surface of the magazine rack (10) that stands integrally from the apparatus frame (M), and the opening of the feed slit (12) is the mount (1). Is adjusted by the lifting operation screw 杆 (14) of the opening / closing shutter (13).

It can move. Moreover, as shown in FIGS. 12 and 13, the kick plate (15) in the retracted standby state partially protrudes to the bottom of the opening of the magazine rack (10) and handles the next mount (1) from below. Therefore, the mount feeding leakage from the magazine rack (10) and the overlapping feeding of two or more sheets do not occur.

(18) is also a mount-feed rubber roll of the mount feed mechanism (11), and is horizontally laid horizontally on the apparatus frame (M) while being positioned substantially directly below the mount feed slit (12). A one-way clutch (20) is attached to and integrated with either the left or right extension end of the rotating rubber roll shaft (19) as shown in FIG. The one-way clutch (20) is for preventing reverse rotation of the rubber roll (18).

Further, (21) is a horizontal rotation feeding shaft supported in a state of projecting from the apparatus frame (M) in the same lateral direction as the rotating rubber roll shaft (19), and is parallel to the rotating rubber roll shaft (19). In this, an input sprocket (22) having a relatively large diameter, a kick plate transmission wheel (23) and a rubber roll transmission wheel (24) each having a smaller diameter are attached and integrated.

Then, the input sprocket (22) on the rotation feeding shaft (21) is driven by a geared motor (25) with a brake in the frame of the device frame (M), so that the first and second intermediate shafts as shown in FIGS. (26a) (26b) The transmission sprockets (27a) (27b) (27c), endless transmission chains, timing belts (28a) (28b) (28c), etc. are rotationally driven. .

Furthermore, the kick plate transmission wheel (23) on the rotary feed shaft (21) and the leg block (16) of the mount kick plate (15) are pivotally connected via a first crank arm (29a). On the other hand, the transmission wheel (24) for the rubber roll on the rotary feed shaft (21) and the one-way clutch (20) on the rotary rubber roll shaft (19) are connected via another second crank arm (29b). It is pivotally connected.

That is, when the rotation feeding shaft (21) of the mount feeding mechanism (11) is rotated in the direction of the arrow (R1) in FIG. 13 using the geared motor (25) with a brake as a drive source, the mount kick plate (15) When the first crank arm (29a) pivotally connects the leg block (16) and the eccentric portion of the kick plate transmission wheel (23) to move backward in the direction of the arrow (r) in FIG. At the same time, the rubber roll (18) is moved by the swinging action of the second crank arm (29b) that pivotally connects the one-way clutch (20) and the eccentric part of the transmission wheel (24) for rubber roll. Rotate in the direction R2) and feed the mount (1) from the mount feeding slit (12) of the magazine rack (10) forward (f1) as shown in FIG. It has become.

The mount (1) fed out from the mount feeding slit (12) of the magazine rack (10) to the front (f1) continues as the rotation of the rotary feed shaft (21) continues as indicated by the arrow (f2) in FIG. By the mount kick plate (15) moving forward in the direction, the chain follower roll, which will be described later, of the mount transport section (B) is kicked between the mount press roll from above and securely clamped. Become.

In the process in which the mount kick plate (15) moves forward in the direction of the arrow (f2) in FIG. 14 and kicks the mount (1) forward to the mount transport section (B), the rubber roll (18) is moved to FIG. When rotating in the direction opposite to the arrow (R2) direction, the rotation is blocked by the action of the one-way clutch (20) and resists the mount (1) in combination with the rubber roll (18). There is no risk of damage, deformation, etc.

Next, the board transport section (B) is on the front side (downstream side) of the board supply section (A), and one by one by the kick plate (15) of the mount feeding mechanism (11) in the mount supply section (A). A pair of parallel slide guide groove rails (30) for receiving the left and right sides of the mount (1) kicked forward, and the mount (1) one by one along the mount slide guide groove rail (30) It consists of an endless link chain (31) that is sequentially conveyed forward.

(33) is a link chain drive sprocket pivoted on the device frame (M), from the geared motor (25) with brake via the first intermediate shaft (26a), the transmission chain or the timing belt (34). It is rotated by the distributed power received. Similarly, (35a) and (35b) are a pair of front and rear link driven rollers for the link chain, but the backing presser roll (36) is elastically biased from above to the rear (upstream) chain driven roll (35b). ing.

Then, the mount (1) kicked forward by the kick plate (15) of the mount feeding mechanism (11) in the mount supply section (A) is connected to its mount press roll (36) and chain follower as shown in FIG. It enters between the upper and lower sides of the roll (35b) and between the left and right sides of the mount slide guide groove rail (30), and is then captured by the mount locking claw (32) where the link chain (31) arrives. As shown in FIGS. 15 and 16, it is pushed forward smoothly and stably.

The mount (1) has a length relationship in which the mounts (32) in the link chain (31) are adjacent to each other between the mount locking claws (32). The fixed interval of the pawl (32) and the left and right mutual interval of the mount slide guide groove rail (30) can be changed and adjusted according to the length (L1) and width (W1) of the mount (1).

As described above, the adhesive application section (C) is arranged in the middle of the mount transport section (B). This is the mount transported by the link chain (31) as shown in FIGS. A plate roll (37) facing the upper surface of (1), a plate receiving roll (38) sandwiching the mount (1) between the upper and lower sides thereof, an adhesive containing pan (39), and its containing pan (39) And an adhesive application roll (40) for transferring the adhesive (2) to the rubber plate (37a) of the plate roll (37), excluding the plate receiving roll (38) and its elevation adjustment handle (41). The whole is attached to the apparatus frame (M) via a gantry (42). In addition, the doctor which scrapes off the excessive adhesive agent (2) at the time of the said transfer is abbreviate | omitting illustration.

The plate roll (37) is also moved from the geared motor (25) with brake to the transmission gears (43a) (43b) that mesh with each other on the first and third intermediate shafts (26a) (26c) When the third intermediate shaft (26c) and the transmission sprocket (45a) (45b) on the plate roll shaft (44) and the power distributed through the transmission chain or timing belt (46) are rotated, the adhesion The agent (2) is transferred to the rubber plate (37a) of the plate roll (37) through the adhesive application roll (40) rotated in the opposite direction to the plate roll (37), and the plate roll (37). And plate receiver What pinching action with phase 俟 mount (1) according Lumpur (38), so that the adhesive on the upper surface of the base sheet (1) (2) is applied. The plate receiving roll (38) is also rotationally driven in the opposite direction to the plate roll (37). (47) is an input gear on the adhesive application roll shaft (48), which meshes with another transmission gear (49) on the plate roll shaft (44). The mount (1) after application of the adhesive is continuously pushed forward (downstream) by the mount locking claw (32) of the link chain (31) and conveyed.

In that case, the length (L), width (W) and position of the adhesive (2) to be applied to the mount (1) are the size and shape of the mount (1) and the shrink film (3), the positional relationship of the attachment, etc. Can be set appropriately. The plate roll (37) for applying the adhesive (2) to the mount (1) and the mount locking claw (32) of the link chain (31) that pushes the mount (1) forward and conveys it do not interfere with each other. Needless to say, they are installed in a relational state (see FIG. 16) that is shifted in the horizontal direction.

Next, the film supply section (D) is disposed on the front side (downstream side) of the mount transport section (B). As is apparent from FIGS. 5, 6 and 11 and FIGS. 1) and a magazine rack (50) for film that accommodates a certain unit amount (for example, 100 to 200) of shrink film (3), and a film (3) from the rearward outlet of the magazine rack (50), It consists of a film feeding mechanism (51) that feeds out one sheet at a time in the downward direction where the mount (1) after application of the adhesive comes.

(52) is a pair of left and right fixed masts erected integrally from the apparatus frame (M), and the magazine rack (50) for film is substantially U-shaped when viewed from the front and rear directions between the left and right. It is erected in a downwardly inclined state with a certain angle that gradually decreases toward the exit.

As described above, the shrink film (3) is formed into a bag-like sheet film that is heat-sealed or folded in advance at the bottom (4), and into the inside of the magazine rack (50) in the extraction enlarged portion of FIG. As shown in the figure, the entrance is aligned in a tilted upright posture, and is subjected to vibrations from an air vibrator (not shown) and the like, and in that tilted upright posture, the magazine rack (50) sequentially advances to the rearward exit, so to speak down. It is supposed to be.

(53) is a film suction soccer (vacuum suction port) of the film feeding mechanism (51), and is located in the middle of the supporting link arm (54) as a positional relationship facing the rear outlet of the film magazine rack (50). Is pivotally attached by a horizontal pivot fulcrum shaft (55) to a stationary mast (52) standing up from the device frame (M).

(56) is a horizontal cam shaft parallel to the pivot fulcrum shaft (55) of the link arm (54) that supports the football (53), and is horizontally mounted between the left and right of the fixed mast (52). The left and right ends of the camshaft (56) include a plate cam (57) for moving the soccer (53) in the vertical direction by a fixed rotation angle (α), and the geared motor (25) with a brake. The input sprockets (58) that receive the distributed power are respectively mounted and integrated.

And the upper end part of the vertical link arm (60) provided with the roller (59) that always contacts the plate cam (57), and the rear end part of the link arm (54) supporting the soccer (53), It is pivotally connected via a fixed length forward and backward advance / retreat arm (61). Needless to say, (62) is a swinging intermediate fulcrum shaft of the vertical link arm (60), and is pivotally attached to the fixed mast (52).

That is, when the plate cam (57) is rotated, the soccer (53) is directed to the rearward exit of the film magazine rack (50) as shown in FIGS. 17 to 20 based on the predetermined cam profile.

It can be reciprocated only (for example, about 55 degrees).

In that case, as is apparent from FIG. 5, the link chain (upstream side) and the front side (downstream side) of the adhesive application part (C) interposed in the middle of the mount conveyance part (B) 31) The first and second position detection sensors (63a) and (63b) for detecting the front end of the mount (1) conveyed by the head (31) are exposed, and the first position detection sensor (63a) of the mount (1) The soccer (53) starts to adsorb the shrink film (3) from the film magazine rack (50) by the output electric signal that has detected the front end, and then the second position detection sensor (63b) uses the front end of the same mount (1). The relationship is set so that the soccer (53) releases the suction of the film (3) by the output electric signal detected.

That is, the soccer (53) separates the shrink film (3) adsorbed at the raised position (H1) at the lowered position (H2) moved by a fixed rotation angle (α), and the separated film (3). Is received by the suction roll so as to hang down to the circumferential surface of the suction roll described later. The time required from the ascending position (H1) where the soccer (53) adsorbs the film (3) to the descending position (H2) where the adsorbing is released, and the front end of the mount (1) are defined as the first position detection sensor (63a). The required time from the detection to the detection by the next second position detection sensor (63b) is matched and matched with each other.

More specifically, the first position detection sensor (63a) is fixed, and the attachment position of the second position detection sensor (63b) is moved in the front-rear direction, whereby the shrink film (3) with respect to the mount (1).
