[0007]
【Example】
Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
1 to 5 show a container delivery apparatus according to the present invention. FIG. 1 is an enlarged plan view showing a main part of the container delivery apparatus, and FIG. 2 is a front cross-sectional view showing an enlarged main part of the container delivery apparatus. 3 is a cross-sectional view taken along line AA in FIG. 2, FIG. 4 is a front view and a side view showing a state in which a part of the container delivery device is cut out, and FIG. FIG.
[0008]
In FIG. 1, 1 is a 1st conveyance conveyor which is arrange | positioned at a drink production line and conveys the container 2 (refer FIG. 4) to a downstream processing apparatus (for example, caser). Guides 3 are arranged on both sides of the first conveyor 1 to guide the containers 2 to be conveyed.
[0009]
An accumulator 4 is arranged in the middle of the conveyance of the first conveyor 1 so as to be orthogonal to the first conveyor 1, and when the downstream processing apparatus stops for some reason, The container 2 is received and accumulated. The accumulator device 4 includes an accumulator conveyor (hereinafter referred to as a second transport conveyor) 6 that is connected to the first transport conveyor 1 via a jumper plate 5. The second conveyor 6 can be rotated forward and backward by a drive motor (not shown), and is driven so as to convey the container 2 to the right side of FIG. 1 during normal rotation and left side of FIG. The container 2 is conveyed.
[0010]
Moreover, the conveyance surface of the 2nd conveyance conveyor 6 becomes the uneven | corrugated shape (refer FIG. 3) by which the convex part 6a and the recessed part 6b continued continuously in the cross section orthogonal to the conveyance direction, and also the recessed part 6b is a conveyance direction. Are arranged at predetermined intervals (see FIG. 2), and an engaging portion 6c formed at an acute angle is formed on the first conveying conveyor 1 side, and a curved portion 6d is formed on the opposite side to the first conveying conveyor 1. Is formed.
[0011]
Extrusion means 7 is disposed in the accumulator device 4. The pushing means 7 is attached to the tips of a plurality of holders 8 disposed on the second conveyor 6, weights 9 placed on the holders 8, and rods 10 penetrating the weights 9. The extrusion guide 11 is in contact with the container 2, and the rod 10, the holder 8, and the weight 9 serve as support means for supporting the extrusion guide 11.
[0012]
Engagement pieces 8a are formed on the bottom surface of each holder 8, and when the second transport conveyor 6 performs a reverse rotation for discharging, it engages with the engaging portion 6c to transfer the pushing means 7 to the second transport. Move in conjunction with the conveyor 6.
[0013]
Further, when the extrusion guide 11 is at the upstream end position (solid line position on the left side in FIG. 1), the distance L between the contact surface 11a of the extrusion guide 11 and the engagement piece 8a on the first transport conveyor 1 side (FIG. 2). The extrusion guide 11 is supported so that the relationship between the reference width and the transfer width L ′ (see FIG. 1) of the transition plate 5 is L ≧ L ′, and the container 2 on the transition plate 5 is completely transferred to the first transport conveyor. It can be handed over to 1.
[0014]
When the second conveyor 6 is rotating forward for accumulating, the extrusion means 7 moves without slipping on the second conveyor 6 due to the load of the weight 9, and is overloaded for some reason. Since the curved portion 6d and the engaging piece 8a are not engaged with each other, the pushing means 7 can be separated from the second conveyor 6.
[0015]
Thus, the extruding means 7 does not require a separate driving means, and moves using the driving of the second transport conveyor 6.
[0016]
Furthermore, the detecting means 12 is provided in the pushing means 7, and it is confirmed that the pushing means 7 has reached the upstream end position and the downstream end position (the two-dot chain line position on the right side in FIG. 1) of the second transport conveyor 6. It is detected by the proximity sensor 13 disposed in the accumulator device 4.
[0017]
A swing guide 14 is disposed at a position facing the accumulator 4 of the first transport conveyor 1, and when the sensor 15 provided downstream of the first transport conveyor 1 detects the stagnation of the containers 2. The container 2 that protrudes on the transport path of the first transport conveyor 1 (in the state of the two-dot chain line in FIG. 1) and is transported by the control means (not shown) is guided to the accumulator 4.
[0018]
Next, the operation of the container delivery device according to the above configuration will be described.
First, when the container processing apparatus arranged downstream is operating normally, the container 2 is continuously conveyed downstream by the first conveyor 1. At this time, the swing guide 14 is retracted and is in a position (a position indicated by a solid line in FIG. 1) that does not interfere with the conveyance of the container 2. The extrusion guide 11 is positioned along the transport path of the first transport conveyor 1 and guides the container 2 together with the guide 3.
[0019]
Here, when the container processing apparatus arranged downstream stops due to trouble and the container 2 stays up to the position of the sensor 15 on the first transport conveyor 1, the swing guide 14 is advanced by a control device (not shown). The second conveyor 6 is rotated forward. Then, the containers 2 transported on the first transport conveyor 1 are brought into contact with the swing guide 14 and transferred to the second transport conveyor 6 through the transition plate 5 and are sequentially accumulated on the second transport conveyor 6. The At this time, the extrusion guide 11 moves at the same speed as that of the second transport conveyor 6, but even if an overload is applied for some reason, the engaging portion 8a of the holder 8 is different from the curved portion 6d of the second transport conveyor 6. Since it does not engage, it will only slide on the 2nd conveyance conveyor 6, and damage to components can be prevented beforehand.
[0020]
Next, when the downstream container processing apparatus resumes operation, the container 2 staying on the first conveyor 1 is conveyed downstream, and it is detected that the container 2 is no longer at the position of the sensor 15. Then, the swinging guide 14 is moved backward, and the second conveying conveyor is reversed to start the discharging operation of the accumulated container 2. The container 2 is transported toward the first transport conveyor 1 along with the movement of the second transport conveyor 6, and is placed on the transition board 5. The container 2 on the transition plate 5 moves while sliding toward the first transport conveyor 1 by the pressing force of the subsequent container 2 that is subsequently placed, and is sequentially delivered to the first transport conveyor 1 in due course. The payout operation may be started during the accumulating operation in which the pushing means 7 does not reach the downstream end position.
[0021]
Thus, when the extrusion guide 11 moves together with the second transport conveyor 6 and moves to the upstream end position, it comes into contact with the container 2 on the transition board 5. The pushing means 7 is formed on the bridge plate 5 by the driving force of the second transport conveyor 6 and the load of the weight 9 due to the engagement piece 8a of the holder 8 being engaged with the engagement portion 6b of the second transport conveyor 6. All the containers 2 placed are moved to the first conveyor 1 side and delivered. When the proximity sensor 13 detects that the extrusion guide 11 has reached the upstream end position, the second conveyor 6 is stopped. To complete the payout operation.
[0022]

As a result of employing the above configuration, the present invention can obtain the following effects.
(1) It is not necessary to provide a separate drive means as a container delivery device.
(2) Since the weight can be reduced, the apparatus can be made compact.
(3) Even if an overload is applied during accumulation, there is no risk of damage to the device.
