Will be described.

FIG. 1 is a perspective view of a main part of a stopper according to an embodiment of the present invention, FIG. 2 is a perspective view of a packaging container, FIG. 7 is a plan view of an infeeder according to the embodiment of the present invention, and FIG. 9 is a side view of a main part of the infeeder according to the embodiment of the present invention, FIG. 10 is a diagram showing a gate opening / closing mechanism according to the embodiment of the present invention, and FIG. It is a front view of the package holder in embodiment of this invention.

In the figure, 13 is a main wheel, 14
Is a package holder, 15 and 16 are holding parts, 21 is a conveyor, and 32 is an infeeder. Here, since each packaging container 17 is held by the holding portions 15 and 16, respectively, the packaging container 17 held by the holding portion 16 is referred to as a first packaging container 17, and
The packaging container 17 held by the second packaging container 17
And

Then, a first stopper 85 is provided at a predetermined position on the conveyor 21, and the first stopper 85 is provided.
The first packaging container 17 transported by 1 is stopped by the first stopper 85. The first stopper 85 is adapted to be advanced and retracted by an air cylinder 87.
If it is not necessary to attach it to the device, it will be retracted. In that case, each packaging container 17 conveyed by the conveyor 21 passes through the first position S1, is guided by the guide 86, and is sent to the eighth position S8.

A second stopper 88 is provided upstream of the first stopper 85 in the traveling direction of the conveyor 21. The second stopper 88 is moved forward and backward by an air cylinder 89, and is closed. The position and the retreat position are taken. Then, the second stopper 88 is advanced,
By placing it in the closed position, the second packaging container 17 can be stopped. In this way, when the first and second packaging containers 17 are stopped by the first stopper 85 and the second stopper 88, the air cylinders 35, 3
6 is driven, and the second packaging container 1 is
7 is pushed into the holding portion 15, and the first packaging container 17 is pushed into the holding portion 16 by the pusher 34.

For this purpose, the first sensor Se1 is located slightly upstream of the first stopper 85 in the traveling direction of the conveyor 21 and the second sensor Se2 is located slightly downstream of the second stopper 88. A third sensor Se3 is provided slightly upstream of 88. The second
When the sensor Se2 detects the first packaging container 17, the control device (not shown) drives the air cylinder 89 to move the second stopper 88 forward. Then, when the first sensor Se1 detects the first packaging container 17 and the third sensor Se3 detects the second packaging container 17, the control device drives the air cylinders 35 and 36, and the pusher 3
3, 34 is advanced.

As described above, since the first packaging container 17 is stopped and positioned by the first stopper 85 and the second packaging container 17 by the second stopper 88, the pushers 33 and 34 are advanced. At the same time, it is possible to prevent the adjacent packaging containers 17 from interfering with each other. Therefore, since the packaging container 17 does not fall, it is not necessary to stop the operation of the lid attaching device 11 (FIG. 3) and raise or remove the falling packaging container 17.

Further, the conveyor 21 and the package holder 1
4, a gate 20 is disposed movably in the up-down direction, from when the first packaging container 17 reaches the first position S1 to when the pushers 33, 34 start to advance. The gate 20 is moved above the surface of the conveyor 21 by a predetermined amount. Therefore, the packaging container 17 does not fall on the package holder 14.

The packaging container 17 has a top wall 17.
a, side walls 17b to 17e and a bottom wall 17f. For example, the sealing portion 201 is provided on the top wall 17a, and the side walls 17b, 17e.
The ear piece 202 is fused in a state of being bent near the upper end of d. Therefore, in the upper half part AR1 of the packaging container 17, each of the side walls 17b to 17e is relatively easy to maintain the shape and extends substantially vertically.
In the lower half part AR2, the side walls 17b to 17e are
It is relatively difficult to maintain the shape,
It swells outward by being pushed by the liquid food inside. In addition,
The lower half part AR2 forms a bulging part.

Therefore, the packaging container 17 conveyed by the conveyor 21 is moved to the first stopper 85 and the second stopper 85.
When the lower half AR2 hits the first stopper 85 and the second stopper 88 when being stopped by the stopper 88, the lower half AR2 is deformed. At this time, the reaction from the first stopper 85 and the second stopper 88 and the reaction from the liquid food due to the deformation of the lower half part AR2 greatly apply to the packaging container 17, and the packaging container 17 may be stopped at a predetermined position. I can no longer do it.

In this case, the packaging container 17 is
In addition to the fact that the packaging container 17 cannot be reliably set in the package holder 14 due to 3, 34, the packaging container 17 may be crushed by being pressed against the package holder 14. Therefore, the cost of the packaging container 17 increases. Therefore, the first stopper 85 and the second stopper 88 are provided with the first stopper 8 so that the recoil when stopping the packaging container 17 can be suppressed.
5 is a first arm 8 fixed to the air cylinder 87
5a and a second arm 85b extending at right angles to the first arm 85a, a portion of the second arm 85b corresponding to the upper half AR1, particularly a flat portion below the lug 202. At a position corresponding to 203, a rod-shaped contact member 85c is formed so as to protrude. The second stopper 88 includes a first arm 88a fixed to the air cylinder 89, and a second arm 88b extending perpendicular to the first arm 88a.
A rod-shaped contact member 88c is formed at a position corresponding to the flat portion 203 in FIG.

In this case, when the packaging container 17 transported by the conveyor 21 reaches the first stopper 85 and the second stopper 88, the flat portion 203 hits the contact members 85c and 88c, and the packaging container 17 is stopped. Can be At this time, the lower half part AR2 does not contact or slightly contacts the first stopper 85 and the second stopper 88. Therefore, since the lower half part AR2 is not deformed, the reaction from the first stopper 85 and the second stopper 88 and the reaction from the liquid food due to the deformation of the lower half part AR2 may greatly add to the packaging container 17. Absent. Therefore, the packaging container 17 can be accurately stopped at a predetermined position.

Then, the packaging container 17 is pushed into the pusher 3.
Since the packaging container 17 can be reliably set in the package holder 14 by the use of 3, 34, the packaging container 17 is not pressed against the package holder 14 and crushed. Therefore, the cost of the packaging container 17 can be reduced. Further, since it is not necessary to stop the operation of the lid attaching device 11, the working efficiency can be improved.

By the way, the package holder 14
It comprises a bottom plate 90, a back plate 91, and first to fourth side plates 92 to 95, and the holding portion 15 is provided between the first and second side plates 92 and 93, and between the third and fourth side plates 94 and 95. The holding portion 16 is formed at the bottom. Then, each packaging container 17 is placed in the holding section 1.
When the pushers 33 and 34 are pushed into the pushers 5 and 16, the pushers 33 and 34 stop moving forward for a predetermined time so that the package 17 does not fall down due to interference between the package 17 and the first to fourth side plates 92 to 95. For example, when the packaging container 17 is in the first position S1
The width of the holding portions 15 and 16 is widened from when the pusher 33 reaches the forward position until the pushers 33 and 34 finish moving forward. Therefore, the first and third side plates 92 and 94 are fixed to the bottom plate 90 and the back plate 91, while the second and fourth side plates 93 and 95 are fixed to the bottom plate 90 and the back plate 91. It is arranged so that it can move freely. In addition, the first to fourth side plates 92 to 95
Are formed with tapered surfaces 92a to 95a, respectively.

Then, on the back side of the back plate 91, a back plate 91
And a sleeve 97 that slides along the fixed rod 96 and supports the second and fourth side plates 93 and 95. The fixed rod 96 is fixed to the fixed rod 96. Spring 9 between sleeve 97
8 is installed. Further, the arm 10 is moved around a pin 101 set at a predetermined position on the main wheel 13.
2 is swingably disposed, and a projection 103 is formed substantially at the center of the arm 102.

A rod 107 of an air cylinder 106 is connected to the tip of the arm 102, and by driving the air cylinder 106, the arm 102 takes a forward position shown in FIG. 10 and a retracted position (not shown). . When the arm 102 is moved to the forward position, the protrusion 103 is moved to the roller 104 provided on the sleeve 97.
To move the sleeve 97 rightward in FIG. As a result, the second and fourth side plates 93 and 95 are also shown in FIG.
Moved right at 0. In addition, windows 111 and 112 are formed in the back plate 91 to fix the second and fourth side plates 93 and 95 to the sleeve 97.

Then, each packaging container 17 is held by the holding parts 15, 1
6, the arm 102 is located at the retracted position, and the protrusion 103 is separated from the roller 104. As a result, the sleeve 97 is moved leftward in FIG. 10 by the urging force of the spring 98. In this way, from the time when the packaging container 17 reaches the first position S1 to the time when the pushers 33 and 34 finish moving forward, the holding portions 15 and 1
6, the width of each packaging container 17 is increased.
In pushing the package containers 5 and 16, the packaging container 17 does not interfere with the first to fourth side plates 92 to 95. Therefore, the packaging container 17 does not fall.

The eighth position S adjacent to the first position S1
8 is set, and at the eighth position S8, the packaging container 17 held by the package holder 14 is pushed out onto the conveyor 21 by an outfeeder (not shown).
Also in this case, while the packaging container 17 is being pushed by the out feeder, the width of the holding portions 15 and 16 is increased by driving the air cylinder 106.

The present invention is not limited to the above embodiment, but can be variously modified based on the gist of the present invention, and they are not excluded from the scope of the present invention.
