Description

[Detailed Description of the Invention] The present invention relates to a mechanism for aligning and discharging containers at high speed, and even relatively lightweight containers such as synthetic resin containers and paper containers can be aligned at high speed and filled with contents. The aim is to provide a new mechanism suitable for sequentially supplying capping and other processing steps.

Relatively lightweight containers made of synthetic resin or paper are widely used as containers for containing beverages, food, cosmetics, and other products. When packaging, packaging, cleaning, and sterilizing containers, it is necessary to arrange and send out the containers. That is, for this purpose, a traveling conveyor having a width for placing the containers in an inverted state at the bottom of a hopper which is designed to accommodate a large number of containers in a disorderly manner, and a conveyor located on both sides of the traveling conveyor that moves up and down. An alignment operation board is provided,
Through the interaction between these running conveyors and the alignment operation plate, the containers are sent out with their directions aligned, and the reversal locking member acts on the rows of containers that are aligned and sent out to the top of the machine frame, so that the direction is adjusted. The direction of the containers sent out in the opposite direction is reversed to the forward direction, and then the containers are dropped between the alignment frames on the front of the machine frame. Regarding sending out a plurality of containers in a line by dropping a locked row of containers onto a lower transfer conveyor by releasing the locking operation of the stopper, the present applicant has, for example, disclosed in Japanese Patent Publication Sho. It has been proposed as in Publication No. 46-11729. That is, when such a system is used, it is possible to automatically arrange and send out a large number of containers, which is extremely useful industrially.

However, in the method described above, it is necessary to considerably increase the speed of the transfer conveyor in order to perform the work associated with modern mass production processing, and it is necessary to considerably increase the speed of the transfer conveyor under the conditions where the transfer speed is increased. However, there are drawbacks such as overturning of the containers on the transfer belt or the inability to maintain orderly spacing or direction between the containers. However, as a method to eliminate such overturning of containers or irregularities on the transfer belt, a rotating screw is installed on the transfer conveyor, and the group of containers dropped as described above is received and held between the screws of the rotating screw. It is conceivable that the rotary screw may be transferred at the same time, but even in the case of a device equipped with a rotating screw, the rotational transfer speed of the rotating screw also increases under the speed-up conditions mentioned above, so this has been reduced. If the container does not fit between the screws, the bottom of the container that has been neatly dropped may get caught on the screw and fall, or be thrown out of the transfer conveyor, making it impossible to send out the container in a smooth alignment.

The present invention has been devised after repeated studies in view of the above-mentioned circumstances, and is based on a traveling conveyor that places and transports containers with mouths formed at their upper ends in an upside-down state. In a device in which the containers are sequentially dropped into a frame and then carried out to the side from the alignment frame and the containers are sequentially filled with contents and other processing, the containers are dropped to the side from the alignment frame. As a transfer means for carrying out the container, a transfer screw is provided which receives the container between the spiral protrusions and propels and transfers the container by rotation, and a pocket portion for receiving the container between the transfer screw and the above-mentioned alignment frame, and this pocket portion. An intermediate transfer means is provided with a stopper that can move back and forth to hold the containers received in the alignment frame, and the drive system for the intermediate transfer means is in a stopped or low speed state suitable for receiving the containers dropped from the alignment frame. The present invention proposes to provide a speed change operation mechanism that changes gears in a predetermined cycle to a high speed state suitable for carrying out such processing continuously, and to continuously and orderly send out containers in a high speed state.

To explain the specific embodiment of the device according to the present invention as described above as shown in the attached drawings, the general structural relationship of the device according to the present invention is as follows.
As shown in the figure, hopper 1 is attached to the top of the machine frame.
is provided at the bottom of the hopper 1, and drums 3, 3, 3 are provided at the bottom of the hopper 1.
A plurality of rows of belt conveyors 2 are arranged as shown in FIG. Belt conveyor 2 is the second
Said container 50 as shown in the figure
It has a width suitable for placing the belt conveyors 2, 2, 2... and on both sides of the conveyor rows. The rotary cam 8 provided on the rotary shaft 7 acts vertically on the containers 50 housed in the hopper 1 in an irregular manner, and the cam 8 on each belt 2 acts as shown in FIG. They are placed parallel to each other and transported to the upper part on the right side in FIG. Above-mentioned conveyors 2, 2, 2... rotary blades 9 are provided in the upper part of the rows, and act on the upper ends of the containers 50 that are being lifted in an upright state on each conveyor 2 to topple them and place them on the conveyor 2. Container 50a that has been removed from the lifting process and has been lifted with the mouth of the conveyor 2, 2, 2, etc. provided with a hook-shaped reversal locking member 13 in front of the upper end
As shown in FIG. 1, the container 50 is locked to the opening 50' and dropped from the bottom of the container 50. Items lifted with the bottom leading are dropped directly into the alignment frame 11 from the bottom. It is designed to fit in. Furthermore, as shown in FIG. 1, the above-mentioned alignment frame 11 accommodates the containers 50 that have been lifted and sequentially dropped in the above-described manner in multiple stages. A stopper 18 having upper and lower locking parts 18a and 18b is attached to the lower part.
As shown in FIG. 1, the container 50 is
The stopper 18 rotates about its pivot 18d from the state in which it receives the bottom of the container, and the locking part 18b retreats, causing the bottom container to fall downward, and the upper locking part 18a to drop the container in the uppermost stage. Container 5
0, and when the stopper 18 is then reversed, the locking portion 18
The container 50, which has been locked by the locking portion 18a as described above, and the containers located above the container 50 are dropped onto the container b.

Provided below the above-mentioned alignment frame 11 is an intermediate transfer means 30 that uses a chain or a belt, and the intermediate transfer means 30 has a structure as shown in FIGS. 3 and 4. A front plate 31 is attached, and a folded part 32 is formed on at least one side of the front plate 31. Furthermore, a guide plate 33 is fixed to the front surface of the transfer means 30, and a folded part 32 is formed on at least one side of the front plate 31. A receiving pocket 35 for the container 50 is formed between the guide plate 33 and the receiving pocket 33, and a container stopper 38 is provided below the receiving pocket 35 so as to be movable forward and backward. In addition, for the intermediate transfer means 30 as described above, there is a drive system 43 which is interlocked with a drive shaft 41 via an index table 42, as shown in FIG.
The drive shaft 41 rotates at a constant speed the transfer screw 40 as a lateral transfer means provided further below the transfer means 30 as described above, while the drive system 43 rotates at a constant speed. The table 42 is configured to perform variable speed drive including stopping. That is, the details of the variable speed drive by the drive system 43 are such that the variable speed drive is performed between a deceleration state that is at or near stop and an increased speed state that is equal to or similar to the transfer speed by the transfer screw 40, and as described above. The container 50 is dropped from the alignment frame 11 in a decelerated state as shown in FIG. As shown in FIG. 5, the alignment frame 11 and the intermediate transfer means 30 are provided in a state that is biased rearward in the transfer direction with respect to the transfer screw 40, and as described above, the intermediate transfer is performed from a deceleration state including stopping. While the means 30 is being transported by the deviated distance, the above-mentioned speed increase condition is created.

Further, to explain the intermediate transfer means 30 and the operational relationship before and after it, the timing at which the container 50 is dropped from the alignment frame 11 into the receiving pocket 35 of the intermediate transfer means 30 is such that the transfer screw 40
The number of rotations (transfers) is equal to the number of rows of containers in 1, and the above-mentioned speed change cycle of the intermediate transfer means 30 is also selected in response to this. When changing the conveying speed using an index cam or the like by the intermediate conveying means 30 to form a stopped state, the process of stop → acceleration → high speed → deceleration → stop is repeated, and in continuous drive, it is not possible to achieve a low speed state. , the process of low speed→acceleration→high speed→deceleration→low speed is periodically repeated. The guide plate 33 described above may be provided separately in the transfer means, but since the guide plate 33 is fixed and positioned directly below the alignment frame 11, as shown in FIG. It is clear that the front plate of the alignment frame 11 may be extended downward as a series.

Note that the drive of the transfer means 30 shown in FIG. 5 can be modified and implemented as shown in FIG. 7. That is, the alignment frame 1 is moved from the drive shaft 41 that drives the transfer screw 40 via the deceleration mechanism 44.
A drive cam 36 is provided whose speed is reduced to 1/N with respect to the number N of container rows in 1.
The proximal end engager 37b of the drive lever 37, whose intermediate part is pivoted 37a, is engaged with the cam groove 36a of No. is engaged with the retainer 30d of the transfer means 30a which is slid along the guide 39, and the transfer means 30a has a pocket section of the alignment frame 11 for receiving the container 50, similar to that shown in FIG. The number of container rows is the same as N.

Although the lateral transfer means in the configuration up to FIG. 7 described above uses the transfer screw 40,
Any other appropriate mechanism may be adopted as such a lateral transfer means. For example, as shown in FIGS. 8 and 9, a container receiving frame 61 is continuously disposed on a conveyor 60, and In contrast, a continuous drive system may be provided. Said acceptance slot 6
1 requires a guide plate 63, and such a guide plate 63 is integrated with the guide plate 33 in the intermediate transfer means as shown in FIG. As shown in FIG. 9, it may be formed to hang integrally from the frame 11 portion. Further, as the conveyor 60, a belt or the like may be used, and its continuous drive system may be driven by a drive shaft 41 as shown in FIG. 5 via a bevel gear or the like as shown in FIG. The arrangement phase relationship between the continuous conveyor 60 and the intermediate transfer means 30 is the same as that shown in FIG. Note that the intermediate transfer means 30 and the stoppers 18 and 38 provided on the alignment frame 11 are moved forward and backward using separate operation cylinders 19 and 39, as in the case of FIG.
It is clear that even if 9 has an inclined direction, it is only necessary to change the shape of the interlocking member between it and the stopper 39.

According to the present invention as described above, the containers are transferred in an aligned state by a traveling conveyor that places and transfers the containers in an inverted state, and the containers are sequentially dropped into an alignment frame, and are carried out laterally from the alignment frame to collect the contents of the containers. In a device that sequentially performs filling and other processing of objects, a transfer screw that receives the containers between spiral protrusions and propels and transfers them by rotation is used as a transfer means for carrying out laterally from the above-mentioned alignment frame. Because the container 50 has a certain height and a good product appearance, it can be propelled and transferred at a considerably high speed without falling over or being ejected from the transfer line. It is capable of carrying out continuous conveyance to smoothly carry out predetermined filling and other processing under conditions of continuous mechanical operation, and also has a pocket portion for receiving the container between the transfer screw and the alignment frame as described above. Since the intermediate transfer means is provided with a stopper that can move forward and backward to hold the container received in the pocket, the container is sent to the transfer screw via this intermediate transfer means, and the above-mentioned The drive system for the intermediate transfer means is in a stopped or low-speed state suitable for receiving containers dropped from the alignment frame, and in a high-speed state suitable for continuously carrying out the above-mentioned processing, the number of container rows in the alignment frame, etc. Since a speed change operation mechanism is provided that changes speed according to a predetermined cycle that responds quickly to the movement of the containers, the containers can be dropped from the alignment frame that is stopped in the transport direction of the containers under the same direction transport conditions by the intermediate transport means. This means that the containers that are dropped into the transfer screw, which rotates under fairly high speed conditions suitable for efficient continuous processing, are accurately fed and fitted without coming into contact with the screw projections, etc. Therefore, smooth and high-speed container alignment,
It has the function and effect of making delivery effective and also making it possible to carry out a series of processing operations such as filling, capping, sealing, and packing continuously and smoothly, and is a highly effective device in practical terms. be.
