The goods (tray T) are transported to the elevator (not shown) provided inside the machine body a by the transport conveyor d.

A film wrapping means c (wrapping section) is provided above the elevator, and a film roll placement section (not shown) on the side of the film wrapping means c (packaging section) and a film roll set in the placement section. Film holding means for holding the leading end of the fed film F is provided. The film packing means c that holds and pulls out the film leading end held by the film holding means and transfers it to the film packaging means c (packaging part). Clamping means provided in the (packaging part) is arranged close to the tip of the film holding means.
Further, a cutter is disposed between the film holding means and the clamping means for cutting the film F held and pulled out by the clamping means into a predetermined length.
Further, above the clamping means provided in the film packaging means c (packaging section), there are a left and right folding plate and a rear folding plate (not shown), and a discharge means 4 (discharge pusher) positioned above the rear folding plate. It is arranged.

Therefore, the article to be packaged (tray T) placed on the elevator is pushed up and stretched with respect to the film F stretched on the film packaging means c (packaging part) due to the elevation of the elevator. The product is folded at the bottom of the article to be packaged (tray T) by the left and right folding plates and the rear folding plate, and then the article to be packaged (tray T) is ejected by the discharge means 4 (discharge pusher). While pushing horizontally toward the (heat seal part), the front end of the film F is folded into the bottom of the package by a front folding roller to complete the packaging with the film. And the paper L issued by the arm part 2 and the sticking part 3 of the sticking apparatus B is stuck on the upper surface of the product during the extrusion transfer of the article to be packaged by the discharging means 4 (discharge pusher).
In the film packaging apparatus A of the present embodiment, the sticking device B that sucks the paper descends to the object to be pasted below the sticking device and sticks the paper. It may be above, and the sticking position on the sticking object may be not only the top face of the sticking object but also the side face or the back face.

-Configuration of the sticking device-
The structure of the sticking device B employed in the film packaging device A will be described in detail.
(Overall configuration)
As shown in FIGS. 1 to 4, the sticking device B according to the embodiment of the present invention is a main body 1 that is freely movable left and right (arrow M <b> 1 in FIGS. 1 and 4) on the body a of the film packaging device A. And an arm part 2 supported so as to be freely rotatable in the left-right direction with respect to the main body part 1 (arrow M2 in FIGS. 3 and 4), and freely movable and rotated with respect to the arm part 2 (arrow M3 in FIG. 3). (Arrow M4 in FIGS. 3 and 4) Discharge of a pusher or the like that moves the adhering part 3 supported freely and the tray T wrapped with the film F to the commodity discharge part e which is the adhering position (arrow M5 in FIG. 3). It is comprised by the means 4, and is drive-controlled by the control means 50 mentioned later based on the information input by the input display means h.

(Configuration of the main unit of the pasting device)
As shown in FIG. 3, the main body 1 of the sticking apparatus B has a sheet support shaft 11 that supports a sheet roll R formed by winding the sheet L and a belt-shaped sheet fed from the sheet roll R. A printing unit 12 that prints information and the like, and a cutter unit 13 that cuts a belt-like sheet printed by the printing unit 12 to create a sheet L are provided.
A paper issue port 13a (FIG. 1) through which a paper is issued is provided on the front surface of the main body 1. The belt-like paper printed by the printing unit 12 is held in a standby state in a state where it is discharged from the paper issue port 13a. Then, after being sucked and held by the suction pad 33 constituting the sticking portion 3, the paper L is formed by being cut by the cutter means 13.

At a position below the paper issue port 13 a of the main body 1, a paper placement plate 142 for waiting and holding the belt-like paper so as not to hang down is extended forward, Ensures standby hold.
As described above, the main body 1 of the sticking apparatus B is configured as a paper issuing unit and also as a paper (sticking medium) holding unit that holds the paper to be pasted on standby.

Accordingly, when the main body 1 moves in the left-right direction on the machine body a of the film packaging apparatus A, the holding (standby) position of the sheet is moved in the left-right direction, and the arm portion 2 and the arm portion 2 are moved. The affixing part 3 to be supported moves in the left-right direction as a whole.
The arm unit 2 is not limited to the arm unit 2 that is rotatably supported with respect to the main body unit 1 configured as a sticking medium holding unit. For example, the arm unit 2 is separated from the main body unit 1. The arm unit 2 that is supported and moves in the left-right direction independently, the arm unit 2 that is supported separately from the main body unit 1 and moves in the left-right direction in conjunction with the main body unit 1, and the arm unit 2 that moves with the main body unit 1 It may be supported separately, and the arm part 2 may not move in the left-right direction but can cover the range of movement in the left-right direction of the main body part 1 by a rotational movement.

(Structure of arm part)
Two upper and lower brackets 15a and 15b are provided in front of the main body 1, and the arm 2 is rotatably supported in the left-right direction with respect to the first rotating shaft 15 formed by the brackets 15a and 15b. Yes.
The arm unit 2 reciprocally rotates between the paper suction position P1 and the paper sticking position P2 around the first rotation shaft 15. Then, the second rotating shaft 25 is provided at a position at a predetermined distance from the first rotating shaft 15, specifically, the tip position of the arm portion 2, and the sticking rod 31 of the sticking portion 3 is located at the position of the second rotating shaft 25. Can be rotated and moved up and down, and the sticking portion 3 can be rotated and moved up and down by the second rotation driving means 23 and the vertical driving means 22.

As shown in FIG. 3, the sticking bar 31 protrudes from the lower surface of the arm portion 2, and the sub arm portion 32 is fixed to the lower end thereof. A suction pad 33 is provided on the lower surface of the sub arm portion 32.
As can be seen from FIG. 4, in this embodiment, the distance from the first rotating shaft 15 to the second rotating shaft 25 in the arm unit 2 is larger than the distance from the second rotating shaft 25 to the suction pad 33. In other words, the arc (rotatable range) drawn by the arm portion 2 around the first rotation axis 15 is larger than the arc (rotatable range) drawn by the sticking portion 3 around the second rotation axis 25. A large arc motion by the arm unit 2 enables movement of the paper L to the pasting position, and a small arc motion by the pasting unit 3 enables adjustment of the pasting angle of the paper L.
Note that the magnitude relationship between the arc drawn by the arm portion 2 and the arc drawn by the sticking portion 3 is not particularly limited to the above-described magnitude relationship, and an arc of the same size is also used than the arc drawn by the sticking portion 3. Alternatively, the arc drawn by the arm portion 2 may be small.

(Composition of pasting part)
As shown in FIG. 5, the sub-arm portion 32 of the sticking portion 3 has an upper block 321 and a lower block 322 that are substantially rectangular in a plan view and are connected by a shaft 323, and the lower block 322 with respect to the upper block 321. Is configured to be rotatable. The sticking bar 31 is fixed to one side of the upper surface of the upper block 321, and the suction pad 33 is fixed to the other side of the lower block 322 where the sticking bar 31 is not fixed.
The lower block 322 is formed with an air passage 322a continuous with the suction passage 33a of the suction pad 33, and the upper block 321 has an air passage 321a continuous with the vacuum passage 6a from the pressure adjusting means 6 such as a vacuum pump. Is formed. The air passage 321a of the upper block 321 and the air passage 322a of the lower block 322 are communicated via a release valve 324 that is released as the lower block 322 rotates with respect to the upper block 321.

  Therefore, when the paper L is stuck to the tray T wrapped with the film F from the suction state in which the paper is sucked and held as shown in FIG. 5A, the suction pad 33 is pressed upward by the reaction force of the sticking operation. . Here, the suction pad 33 can be tilted (deformed) by being formed of a material having elasticity as a whole. Therefore, as shown in FIG. 5B, the suction pad 33 is pressed by an upward pressing force. 33 itself tilts (deforms) by the same amount as the rotation amount of the lower block 322, and rotates the lower block 322 about the shaft 323 while keeping the adsorbed paper surface parallel. Then, the release valve 324 is released, the pressure in the suction path 33a of the suction pad 33 is released to atmospheric pressure, the suction force to the paper L is lost, and the paper L is smoothed against the film F on the upper surface of the tray T. Can be affixed to.

(Adsorption pad configuration)
The adhering pad 33 of the sticking part 3 is made of a material having elasticity such as synthetic rubber, for example, and has a substantially cylindrical shape as a whole as shown in FIG. 6, and a main body part 331 constituting the upper part thereof, A conical adsorbing portion 332 that continues below the main body portion 331 and gradually spreads downward, and is continuous below the adsorbing portion 332 and is elastic at a spreading angle larger than the conical spreading angle of the adsorbing portion 332. The skirt portion 333 having a ring shape, and an annular rib 334 provided on the inner periphery of the skirt portion 333 below the adsorption portion 332 and projecting downward in an annular shape. The lower end of the rib is located about 0.5 mm above the lower end of the skirt portion 333.

An attachment portion 331a for fixing the main body portion 331 to the lower surface of the lower block 322 of the sub arm portion 32 of the attaching portion 3 is formed in the upper portion thereof, and the outer peripheral surface of the lower portion of the attachment portion 331a is thin. A buffer portion 331b made up of a plurality of annular groove portions that are hollowed out is formed, and can be tilted with respect to an external force applied to the suction pad 33. In addition, the buffer part 331b which consists of a some annular groove part is not restricted to what is formed by making an outer peripheral surface thin, but can also be formed by a bellows etc., for example. Furthermore, the number of annular grooves may be one.
In addition, as long as the suction pad 33 can be tilted and the suction surface at the time of paper suction can be kept horizontal, an indirect portion or the like is provided in the main body 331, and the configuration is not particularly specified.

The surface of the adsorbing part 332 is flat without forming a thin-walled part, and the waist is formed stronger than the main body part 331. Further, since it has a conical shape that gradually spreads downward, the force for crushing the suction pad 33 caused by the negative pressure in the suction path 33a at the time of paper suction is released slightly downward from the horizontal direction. Therefore, crushing of the suction pad 33 at the time of suction is suppressed.
Since the skirt portion 333 has elasticity that spreads at a large spread angle, the skirt portion 333 is elastically deformed when the paper L is adsorbed and comes into contact with the surface of the paper L on the surface, thereby enabling the paper L to be stably adsorbed. At the same time, the annular rib 334 disposed on the inner periphery of the skirt portion 333 contacts the surface of the sheet L to be sucked, so that the sheet L is not sucked more than necessary, and the sheet L is wrinkled or deformed. To prevent it.

(Driving device drive control)
In the sticking apparatus according to the embodiment of the present invention, each driving means is controlled by the control means 50 shown in FIG.
The left-right direction driving means 16 is a driving means for adjusting the position where the paper L is pasted, and according to the command of the control means 50, according to the left-right direction pasting position of the paper L set by the input display means h, The horizontal position of the main body 1 is changed.
Usually, in order to perform a predetermined number of packaging and pasting processes under the same conditions, it is driven at the time of the first pasting process and is not normally driven until the conditions are changed thereafter.

The front-rear direction driving means 17 is a driving means for adjusting the sticking position of the paper L, and according to the command of the control means 50, the discharging means 4 such as a pusher according to the set sticking position of the paper L in the front-rear direction. The tray T is moved to the product discharge section e. Usually, the tray T is moved in accordance with the lowering timing of the pasting unit 3 in order to perform the pasting process of the paper L by the pasting unit 3 descending to the upper surface of the tray T during the movement of the tray T to the product discharge unit e. The pasting position in the front-rear direction is adjusted by controlling the timing.
Although it is disadvantageous for shortening the sticking time, depending on the products accommodated in the tray T, the heights thereof are uneven, and sticking while the tray T is moving may be difficult to stick to a certain position. In such a case, it is also possible to adjust the pasting position of the paper L in the front-rear direction by adjusting the final movement position of the tray T by the discharging means 4 such as a pusher.

  The first rotation drive unit 21 is a drive unit that drives the arm unit 2 to reciprocate around the first rotation shaft 15 in order to paste a sheet at a position different from the position where the sheet L is issued. The arm unit 2 reciprocates between the paper suction position P <b> 1 and the paper sticking position P <b> 2 by driving the first rotation driving unit 21. The rotation angle from the paper suction position P1 to the paper sticking position P2 is constant regardless of the sticking position to the tray T, and the first rotation driving means 21 can be configured by a simple mechanism that repeats a constant rotational reciprocating operation.

  During the pasting process, the arm unit 2 is moved from the paper suction position P1 and the pasting unit 3 is detached from the paper issue position by the first rotation driving means 21, so The paper L to be affixed to the can be issued. Further, by moving to the sticking position by rotational movement, it is not necessary to convert the rotational movement of the motor into a linear movement, and stable movement is performed.

  The vertical drive means 22 is a means for driving the sticking part 3 up and down with respect to the arm part 2 and performs an ascending operation and a descending action of the sticking part 3 at the time of adsorbing and sticking paper.

The second rotation driving means 23 is a means for changing the direction in which the sheet is stuck by rotating the sticking part 3 around the sticking stick 31, that is, the second rotating shaft 25, with respect to the arm part 2.
Since the movement of the paper L is performed by the rotational movement from the paper suction position P1 to the paper sticking position P2 by the arm unit 2, if the orientation of the paper L is not changed with respect to the arm unit 2, the arm 2 The paper L attached by the rotational movement is rotated while changing its direction, and the end of the paper L on the paper issuing part side interferes with the mechanism around the paper issuing port 13a, and the adhesive surface of the paper L sticks. There is a possibility. Therefore, in the sticking device B of the present embodiment, the sticking unit 3 is moved to the sticking position while maintaining the orientation of the paper L with respect to the machine body a by rotating the sticking unit 3 according to the rotation of the arm unit 2. Then, after the paper L is moved to the sticking position, the sticking direction of the paper L can be freely changed by the angle at which the sticking part 3 is rotated. The paper L can be stuck at a desired position according to the size of T or the like.

(Attachment return control)
The pressure adjusting means 6 such as a vacuum pump is controlled in conjunction with each driving means, and in the vacuum path 6a where the pressure adjusting means 6 and the suction pad 33 are continuous, there is a problem with the pressure adjusting means 6 and the suction pad. In order to detect a pressure increase in the vacuum path 6a due to breakage of 33 or the like, a pressure sensor 51 for detecting the pressure in the vacuum path is disposed. The pressure in the vacuum path 6 a detected by the pressure sensor 51 is transmitted to the control means 50.

Further, as shown in FIG. 5, when the suction pad 33 affixes the paper L to the film F surface covering the tray T, the release valve 324 provided in the vacuum path 6a is released by the reaction force, and the air pressure in the vacuum path Changes from a state close to vacuum to an atmospheric pressure state.
By detecting the pressure change at that time by the pressure sensor 51, the application of the paper L is detected.
When the pressure value detected by the pressure sensor 51 rises above a threshold value stored in advance, the control unit 50 releases the inside of the vacuum path 6a from the vacuum state to the atmospheric pressure state. It is determined that the film is attached to the surface of the film F, and the vertical drive means 22 is controlled to change from the lowering operation to the ascending operation.

(Home return operation)
In the pasting device, it is necessary to quickly return to the original position after pasting the paper together with the pasting operation of the paper in order to shorten the time of the entire pasting process. Although it is necessary to shorten the time required for the return, if the ascending speed is large, a large load is applied at the time of stopping, which may cause an error in stopping at the accurate origin height. The error of the origin position, that is, the initial position with respect to the next suction operation, is a serious problem in the suction operation of the paper using the suction pad 33, leading to suction mistakes and omissions.

In the pasting device according to the embodiment of the present invention, deceleration control is employed in the return operation for returning the origin of the pasting unit 3 to enable quick and accurate return to the origin.
Specifically, as shown in FIG. 7, the arm unit 2 includes an origin stop sensor 52 that detects that the upper end 31 a of the stick 31 of the stick 3 is at the origin stop position, and an upper end 31 a of the stick 31. And a deceleration start sensor 53 that detects that the vehicle is at a deceleration start position that is a position below a predetermined distance from the origin stop position.
The return operation of the sticking unit 3 from the sticking position is performed at a large ascent speed, and the timing at which the deceleration start sensor 53 detects that the upper end of the sticking bar 31 has reached the deceleration start position below the origin stop position by a predetermined distance. Thus, deceleration control of the vertical drive means 22 is performed to reduce the stop load at the home stop position. Thereafter, when the origin stop sensor 52 detects that the upper end of the stick 31 has reached the origin stop position, the drive of the vertical drive means 22 is stopped, so that the accurate return to the origin position can be performed.

(Adjustment of paper application position)
With reference to FIG. 8, the operation | movement which adjusts the sticking position of the paper stuck by the sticking apparatus B to the front-back, left-right direction is demonstrated.
FIG. 8A shows a state in which the paper L printed with “A” is pasted to the center of the tray T without changing the direction of “A” (hereinafter referred to as “reference pasting state”). The main body 1 is arranged on the left side of the machine body a by the left and right direction driving means 16 so that the arm portion 2 is positioned at a substantially central position in the left and right direction, which is the attachment position of the paper L. Then, the sheet L is stuck at the center position of the tray T by controlling the timing of the back-and-forth movement of the tray T by the back-and-forth driving means 17 in accordance with the lowering timing of the sticking part 3 by the vertical driving means 22.
Since the direction of the paper L at the time of pasting is set to be the same as the direction in which the paper is issued, the second rotation is performed in accordance with the counterclockwise rotation operation (m1) of the arm unit 2 by the first rotation driving means 21. The direction of the paper L is always controlled to be the same by rotating the sticking part 3 clockwise (m2) by the same angle by the driving means 23.

FIG. 8B shows a state in which the same sheet L is pasted to the right side position of the tray T (that is, the pasting position is changed in the left-right direction), and the pasting position of the sheet L is the sheet in the reference pasting state. It is set at a position away from the holding position in the left-right direction. In such a case, the left and right position of the main body 1 is changed (m3) by the left and right direction driving means 16 so that the sheet holding (issuing) position itself approaches the sheet application position.
Therefore, the movement from the holding (issuing) position of the paper to the pasting position in the pasting process of the paper L is always a constant rotation operation (m1) of the arm unit 2 by the first rotation driving means regardless of the pasting position of the paper L. The sticking process time according to the sticking position of the paper is not changed, and an efficient sticking process can always be performed.

FIG. 8C shows a state in which the paper L is pasted to the front position of the tray T (that is, the pasting position is changed in the front-rear direction).
When the pasting position of the paper L is located behind the tray T relative to the pasting position in the reference pasting state, the front / rear movement timing of the tray T by the front / rear direction driving means 17 is controlled to adjust the front / rear position of the pasting position ( m4). Specifically, when it is desired to stick the paper L forward, the forward movement timing for the lowering operation of the sticking unit 3 by the vertical drive means 22 is delayed from the timing in the reference sticking state, and the paper L is moved backward. When it is desired to stick to the front, the forward movement timing for the lowering operation of the pasting portion 3 by the vertical drive means 22 is made earlier than the timing in the reference pasting state.

It should be noted that the adjustment of the pasting position of the paper L in the front-rear direction can also be performed by controlling the stop position of the tray.
As described above, the front and rear direction and the left and right sticking positions with respect to the tray T can be adjusted by the drive control of the front and rear direction driving means 17 and the left and right direction driving means 16.

(Adjusting the direction to paste the paper)
With reference to FIG. 9, the operation | movement which adjusts the sticking direction of the paper L with respect to the tray T by the sticking apparatus B is demonstrated.

FIG. 9A shows a case where the application direction of the paper L is applied to the center of the tray T in the front / rear / right / left direction in a direction different from the direction in which the paper L is issued by 180 degrees. Even when the paper L is changed by 180 degrees and pasted, during the rotation (m1) of the arm portion 2 from the paper suction position P1 to the paper pasting position P2, the orientation of the paper L does not change due to the rotational movement. The sticking unit 3 is rotated (m2) to perform pull-out control. After the arm portion 2 reaches the paper sticking position P2, the orientation of the paper L is adjusted by the second rotation driving means 23 by the sticking portion 3 rotating 180 degrees (m5) about the second rotation shaft 25. Yes.
At this time, since the direction in which the sticking part 3 protrudes with respect to the second rotating shaft 25 is opposite to the front and rear, the sticking position of the paper L in the front-rear direction is different from that in the reference sticking state.
In order to respond to the position change, the drive control of the tray T by the front-rear direction driving unit 24 is performed, and the front-rear position of the sticking position is adjusted (m6).

FIG. 9B shows a case where the paper L is attached to the right side portion of the tray T in a direction 180 degrees different from the direction in which the paper L is issued. 9A, during the rotation (m1) of the arm part 2, the sticking part 3 rotates (m2) the sticking part 3 to perform the pull-out control, and then the second rotating shaft 25 is moved. The orientation of the paper L is adjusted by rotating 180 degrees to the center (m5), and the drive control of the tray T is performed by the front-rear direction driving means 24, and the front-rear position of the sticking position is adjusted (m6). In addition, the main body 1 is repositioned to the right (m3) by the left and right direction driving means 16 so that the paper issue position of the main body 1 approaches the paper application position.
In this way, by applying the paper L to the right side of the tray T by changing the orientation of the paper L by 180 degrees, it is possible to create substantially the same application state as when the paper L is applied to the left side of the tray T. This eliminates the need to increase the width of the entire pasting device more than necessary.

FIG. 9C shows a case where the paper L is attached to the right side portion of the tray T in a direction that is 90 degrees different from the direction in which the paper L is issued.
The affixing unit 3 performs pull-out control by rotating (m2) the affixing unit 3 in synchronization with the rotation (m1) of the arm unit 2 from the paper suction position P1 to the paper affixing position P2, and then the second rotating shaft 25. Is rotated 90 degrees counterclockwise (m7) and the orientation of the paper L is adjusted, and the drive of the tray T is controlled by the front-rear direction driving means 24 to adjust the front-rear position of the application position (m8) Is done.
