Are arranged at two places along the direction perpendicular to the paper surface of FIG. 1 so as to be able to abut on both side portions in the width direction of the sheet S. Accordingly, as shown in FIG. 3, the sheet S pulled out downstream while being in contact with the application roller 23 has
A thin band-like adhesive layer 27 along each edge in the width direction of the sheet S
Is formed. The adhesive A is not particularly limited. In addition to a normal adhesive, a pressure-sensitive adhesive or a heat-sensitive adhesive can be used. In particular, the pressure-sensitive adhesive is advantageous in handling. is there. Further, in FIG. 3, the adhesive layer 27 is applied in a continuous linear or band shape, but may be a partially applied intermittent adhesive layer.

The sheet feeding means 14 is rotatably supported by the frame 11, and is located on each of the upper and lower surfaces of the sheet S and has a pair of feeding rollers 29, 29 for changing the feeding direction to the horizontal direction. A pair of upper and lower pinch rollers 30 provided at a position downstream of the feed roller 29, and a belt for feeding the sheet S sent through the pinch roller 30 to the covering position in a substantially horizontal posture. The apparatus includes a circulating mechanism 31 and a press roller 32 that contacts the upper surface of the sheet S and presses the sheet S against the belt circling mechanism 31.

A driven gear 35 is fixed to a rotating shaft 34 of the lower feeding roller 29 of the pair of upper and lower feeding rollers 29. The driven gear 35 is adapted to engage with a main driving gear 36 fixed to an output shaft of a first motor M1 which operates intermittently at a predetermined timing, whereby the driven gear 35 is held by the sheet holding means 12. The roll-shaped sheet S can be sequentially intermittently pulled out and sent out to the belt revolving mechanism 31 side. The upper feed roller 29 is provided so as to be slightly higher than the position shown by a cam mechanism (not shown).
The sheet S is smoothly inserted between the upper and lower feeding rollers 29 when the sheet S is initially laid and the sheet S is replaced.

As shown in FIG. 1, the belt revolving mechanism 31 is provided on a pair of support shafts 38, 39 disposed at respective left and right positions of the frame 11, and provided on the support shafts 38, 39. Two pulleys 40 each upstream and downstream,
41, and a belt 42 wound between pulleys 40 and 41 on the upstream and downstream sides. A driven gear 44 that rotates while engaging with the main driving gear 36 fixed to the output shaft of the first motor M1 is fixed to the support shaft 38 that supports the pulley 40 on the upstream side. Further, the outer diameter of the upstream pulley 40 is set smaller than that of the downstream pulley 41, and the feeding speed of the sheet S sent out by the belt circulating mechanism 31 becomes faster than the sheet feeding speed by the feeding roller 29. A fixed tension can be applied to the sheet S. The support shaft 39 that supports the pulley 41 on the downstream side is rotatably provided by an air cylinder and a rack & pinion mechanism (not shown). The air cylinder is provided after the sheet S is cut by a cutter 45 described later. The sheet S is provided so as to be transferred to the covering position. Here, the position of the sheet S sent to a substantially central portion between the pulleys 40 and 41 on the upstream side and the downstream side is defined as a covering position.

The pinch roller 30 and the upstream pulley 4
A cutter 45 as a cutting device is arranged at an upper position between the positions 0 and 0. The cutter 45 can be moved up and down through a cylinder 46.
The lowering of 5 enables cutting corresponding to the sheet length required for wrapping for each container P.

As shown in FIG. 3, the respective axial lengths of the feed roller 29 and the pinch roller 30 which are in contact with the application surface side of the adhesive layer 27 of the sheet S are applied to both sides in the width direction of the sheet S. The distance between the adhesive layers 27, 27 is shorter than the distance between the adhesive layers 27, 27, and the feeding roller 29 and the pinch roller 30 are kept out of contact with the adhesive layer 27, and the belt circling mechanism 31 is formed. Belt 42 and adhesive layer 2
7 are provided so as to be able to contact each other. Therefore, in the sheet revolving mechanism 31, the adhesive layer adheres to the outer surface of the belt 42, and the sheet S is sent out with the sheet S adhered to the adhesive layer. At this time, since the press roller 32 is disposed immediately after the pulley 40 on the upstream side, the press roller 32 ensures the adhesion state between the adhesive layer 27 of the sheet S and the outer surface of the belt 42. The length of each of the feeding roller 29 and the pinch roller 30 in the axial direction that comes into contact with the surface of the sheet S on which the adhesive layer 27 is not applied can be longer than the width of the sheet S. In addition, the feeding roller 29 that is in contact with the application surface side of the adhesive layer 27 can also be longer than the width of the sheet S. In this case, the feeding roller 29 corresponds to the area where the adhesive layer 27 is applied. 2
It suffices if the diameter of 9 is partially reduced so that the feeding roller 29 does not contact the adhesive layer 27.

The displacement means 15 comprises a cylinder device 50 as a lifting device for raising the container P. The cylinder device 50 is provided with a push-up plate 51 at the upper end for contacting and supporting the bottom surface of the container P,
Detecting means 53 arranged near this cylinder device 50
Can be raised when it is detected that the container P has reached below the covering position. Therefore, when the cylinder device 50 rises, the sheet S at the covering position can be peeled off from the belt 42 by the container P supported by the cylinder device 50, and the sheet S can be covered on the container P. At this time, as shown in FIG. 3, since a space is formed between each of the pulleys 40 and 41, no interference occurs when the cylinder device 50 rises.

While being held by two support shafts 73 each having a cantilever structure so that the container can be delivered from
The pulley 70 on the downstream side is fixed to a single support shaft 74 extending between the left and right frames 11, as shown in FIG.

The belt conveyor 60 and the suspension transfer device 6
The second motor M2 is arranged at a lower position between the first motor M1 and the second motor M2. As shown in FIG. 2, a driving pulley 77 is fixed to an output shaft 76 of the motor M2, and a belt 78 wound around the driving pulley 77 is connected to a downstream roller 64 of the belt conveyor 60. And a pulley 81 provided at one end of the support shaft 74 of the downstream pulley 70 in the hanging and transferring device 61. Therefore,
When the second motor M2 is driven, the belt conveyor 60 and the suspension transfer device 61 are simultaneously driven to rotate. At this time, since the support shaft 74 of the downstream pulley 70 constituting the suspension transfer device 61 is one, each of the upstream pulleys 69 can be simultaneously rotated.

The sticking means 17 is a pair of pads 84, 84 made of a pair of sponges and the like which can be pressed against the left and right outer surfaces of the container P in FIG. 2, and moves these pads 84 in the direction of separating and approaching each other. A pair of cylinders 85, 85
And a sheet position deviation preventing device 86 for preventing the sheet S covered on the container P by the displacement means 15 from falling off. Each pad 84 is mounted on the lower end of an arm 87 located in the vertical direction, and the upper end of each arm 87 is fixed to the tip of the piston rod 88 of each cylinder 85. Here, the cylinder 85 is supported by a suspension device 90 located on the upper side of the frame 11, as shown in FIG. As shown in FIG. 2, the suspension device 90 includes moving blocks 91, 91 at two upper and lower positions on the base end side, and these moving blocks 91 are positioned at respective upper and lower positions via a rodless cylinder 92. The pads 84 are movably supported along guide rails 93 which are parallel to each other, so that the pad 84 can be moved in substantially orthogonal biaxial directions, that is, in the horizontal direction in FIG. The wrapped container P can be sent out to the transport path 95.

As shown in FIG. 4, the sheet misalignment preventing device 86 includes a rotating piece 101 rotatably supported on the upper end side with respect to the frame 11 and a rotating piece 1.
And a pair of arms 104, 1 supported by the shaft 102 and having a roller 103 disposed at the tip end thereof.

When the sheet S is covered by the displacing means 15, each of the rollers 103 has a flange portion P1 of the container P.
The sheet S is provided on the upper surface side so as to be able to press the sheet S.
Is configured to be able to ascend while rolling on the upper surface side of the flange portion P1. The air cylinder 105 is used when the outer peripheral surface of the container P is sandwiched between the pads 84 and starts transporting.
By acting to slightly raise the position of the roller 103, the container P can be smoothly transported.

The sheet sending means 14, the displacement means 15, the transfer means 16 and the sticking means 17 are provided with sensors and switches (not shown) so as to form a series of flows which do not interfere with each other at a predetermined timing. The sequence control can be performed via the above-described method. Further, when an abnormality occurs in the operation state, an alarm is generated and the operation of the entire apparatus is stopped.

Next, the overall operation of the packaging apparatus 10 will be described.

First, by turning on a predetermined power supply,
The first and second motors M1 and M2 are driven to start operation of each unit of the device. That is, the feeding roller 29 constituting the sheet feeding means 14 rotates and the sheet winding roller 2
The roll-shaped sheet S supported by 1 is sequentially pulled out. Then, the sheet S is applied with the adhesive A in two rows in contact with the application roller 23 of the adhesive application device 13 on the way, and then the pinch roller 30 is rotated by the rotation of the feeding roller 29.
And is sent out to the upstream side of the belt revolving mechanism 31 via the.

The sheet S sent to the upstream side of the belt circling mechanism 31 has an adhesive layer 27 provided on the back side thereof.
Further, since the pressing force from the press roller 32 is received from above, the sheet is fed to the covering position in a state of being in close contact with the belt. At this time, since the speed of the belt rotation mechanism 31 is set to be higher than that of the feeding roller 29, a constant tension is applied to the sheet S. Then, at a position where the sheet S is pulled out by a predetermined length, the cutter 45 is moved.
Descends to cut the sheet S, and the cut sheet S
Is further transferred to the coating position by the rotation of the pulley 41 on the downstream side. At this time, the driving of the first motor M1 is temporarily stopped, and the subsequent sheet drawing and feeding are stopped. Further, as described above, the sheet S is cut by the cutter 45 in a state where tension is applied, and therefore, the cutting and separation can be performed extremely smoothly.

In parallel with this, a container P containing fruits and the like
Is transferred via the belt conveyor 60,
The hanging and transferring device 61 supports the flange surface P1 of the container P and sends it out below the covering position. Before the container P reaches the covering position, the swing arm 55 is in the inclined position, but the swing arm 55 is displaced by the container P reaching the covering position to a position where it contacts the locking member 56. I do. When the swing arm 55 comes into contact with the locking member 56, the stop switch 58 specifies that the container has reached the position below the covering position, that is, just above the cylinder device 50. At this time, the sheet S is simultaneously located or waiting at the covering position. And
The sheet S is peeled off from the belt 42 and is put on the opening of the container P by the cylinder device 50 being further raised above the covering position while pushing the container P upward. At the time of this ascent, the sheet S is removed from the container P by the rollers 103 of the sheet misalignment prevention device 86.
The sheet S is pressed against the container P so as not to fall off.

When the container P has been lifted in this way,
By moving the roller 103 further upward, the pad 8
4 from the initial separation width, the adhesive layer 27
Is pressed against and adhered to the outer surface of the container P,
The pressed state of the sheet S is released. Thereby, while the cylinder device 50 descends and waits for the next container P,
The first motor M1 is driven again to feed the sheet S to the covering position.

While the sheet S is adhered by the pad 84, the suspension device 90 supporting the pad 84 moves rightward in FIG. 1 along the guide rail 93, and moves to the upstream position of the roller transport path 95. Then, after the container P is released, the container P returns to the position above the coating position and waits for the next container. At this time, the roller 10 of the sheet misalignment prevention device 86
3 again goes down to the lower limit and waits at the pressing position of the next container.

When a heat-sensitive adhesive is used as the adhesive A, the pad 84 may be provided with a heat bonding device.

Therefore, according to this embodiment, it is possible to continuously perform the sheet covering and the sticking on the container P while sending out the sheet S and the container P, which is compared with the manual packaging efficiency. The efficiency can be dramatically improved.

The configuration of each part of the apparatus according to the present invention is as follows.
The present invention is not limited to the illustrated configuration example, and various changes are possible as long as substantially the same operation is achieved.
For example, in the above-described embodiment, the case where the covering position of the sheet S is substantially horizontal has been illustrated and described. However, as long as an object to be accommodated such as fruit does not spill out of the container, the inclined position may be used.

In the above embodiment, the adhesive A is applied to the sheet S. However, the adhesive may be applied to the outer surface of the container P. In this case, the belt revolving mechanism 31 constituting the sheet sending means 14 may be of a vacuum type, for example, so that the sheet S can be sent while being closely contacted. In addition, it is also possible to use a sheet to which an adhesive has been applied in advance.

Further, in the above-described embodiment, the first and second motors M1 and M2 are employed, but the present invention can be similarly implemented by a single motor. In this case, a plurality of rows of pulleys and belts or sprockets and chains connected to a single motor output shaft are provided, and a series of operations are performed while adjusting the timing of each unit of the apparatus through an appropriate cam or clutch mechanism. Can be done.

[0044]

As described above, according to the present invention,
This makes it possible to attach the sheet in a state where it is accurately positioned with respect to the opening of the container, which can eliminate difficulties such as sticking out of the adhesive seen when packaging with the adhesive, and eliminate a series of flow. The effect that packaging can be performed efficiently inside is obtained.

Further, according to the present invention, the container can be supplied to the coating position or lower via the transfer means, and can be raised on condition that the container reaches the coating position or lower. In addition to no empty operation, the sheet can be stuck at an accurate position without any difficulty in the method of putting the sheet over the opening of the container.

Further, the sheet feeding means includes a pair of belt revolving mechanisms which are in contact with both side regions orthogonal to each other in a plane substantially the same as the sheet feeding direction. Since it is possible, it is possible to prevent the sheet from fluttering at the time of this sending, and it is not necessary to take measures to prevent fluttering such as a vacuum mechanism.

Further, since a certain tension can be applied to the sheet at the time of feeding the sheet, when the container is wrapped, sheet wrinkles that cause irregular reflection of light are not formed. Can be maintained, and the possibility of impairing the clear visibility of the contents can also be prevented.

Further, since a sheet cutting device is interposed between the belt revolving mechanism and the feeding roller, it is possible to use a raw material in which the sheet is wound in a roll shape, thereby improving the efficiency of the packaging flow. can do.

The sticking means comprises a pair of pads capable of pressing both sides of the sheet covered by the container against the container and movably supports the pad, so that the sheet is attached to the container. The container can be transferred to the next process station while being put on, and post-processing can be performed smoothly.

Further, since a sheet falling-off preventing means capable of pressing the coated sheet to the container is employed, the sheet covering the container is completely adhered until the sheet is completely stuck.
The sheet can be prevented from falling off, and the sheet can be stuck at a stable position at all times.
