Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a device for feeding containers into a holder.
More specifically, the present invention relates to a container feeding device into a holder in which the container is fitted into the holder in an upright state.

``Prior art'' In general, for unstable containers such as paper cups, the bottom of the container is housed in a holder to stabilize it, and in that stable state, the filling liquid is filled or the opening is sealed. ing.

2. Description of the Related Art Conventionally, as a container feeding device for fitting the bottom of a container into a holder, there is known a device that mechanically grips the container and fits the container into the holder.

In addition, in a state in which a large number of containers are rolled over, the containers are aligned and guided in a line in the axial direction of the containers, and the front of the guide member that guides the containers in the conveyance direction is opened vertically downward, and from this opening. It is known that containers are sequentially placed upright and then sequentially dropped into a holder that is being moved.

Furthermore, a container conveyor that conveys the containers, a cylindrical guide member that receives containers rotated and dropped from the tip of the container conveyor and guides them downward in a vertical state, and a cylindrical guide member below the guide member. A device equipped with a holder conveyor for conveying holders is known (Japanese Patent Publication No. 55-17724). ``Problem to be Solved by the Invention'' However, the first container feeding device had a problem in gripping unstable containers. As a result, the grip tends to be incomplete, and attempts to stably hold the device result in the entire device becoming complicated and large.

In addition, in the second container feeding device, the containers are dropped into a holder that is moved from a fixed guide member, and therefore are not suitable for high-speed operation.

Furthermore, in the third container supply device, the container conveyor, guide member, and holder conveyor, which are operated separately, are operated in synchronization, so their relative positions are likely to be out of order, and adjustment work is required relatively frequently. In addition, as the operating speed changes, the amount of containers that are pushed out and dropped from the tip of the container conveyor changes, which changes the falling posture of the containers relative to the guide member. There is a risk that the falling guide may become erroneous and the product may fall out of the guide member.

"Means for Solving the Problem" In view of such circumstances, the present invention includes a first rotary table rotatably provided on the machine frame, and holders provided at equal intervals on the outer periphery of the first rotary table. a holder holding section that holds a holder; a second rotating table that is arranged above the first rotating table and rotates integrally with the first rotating table; and a holder holding section on the second rotating table; A container storage section provided at an upper position to store the container in an overturned state facing the radial direction of the second rotary table, and a container storage section provided on the machine frame to accommodate the underside of the overturned container accommodated in the container storage section. a support member for supporting the container to prevent the container from falling from the container storage section; A notch is provided for rotating and dropping the container downward, and a guide member is provided on at least one of the rotary tables and guiding the rotating and falling container into the holder in a substantially upright state. It is something that

"Operation" According to the above configuration, the container can be dropped while being rotated in a plane perpendicular to the direction in which the container is conveyed by the two rotary tables, that is, in a vertical plane in the radial direction of the rotary table.
Even if the rotation speed of the rotary table fluctuates, it does not have a large effect on the dropping of containers, so that containers can be dropped in a constant state even during high-speed operation.

Since the container storage section, guide member, and holder holding section are provided on the rotary table, their relative positions do not change, and the container can always be dropped in a constant state, which also makes maintenance easier. The container can be freely and securely dropped into the holder for a long time.

"Example" The present invention will be described below with reference to the illustrated example.
In FIG. 4, the containers 1 are conveyed by the conveyor 2 in an overturned state with their bottoms facing forward, with both sides guided by guide members (not shown) in a continuous line. A transport conveyor 3 is provided in front of the transport conveyor 2 and is operated at a faster speed than the transport conveyor 2.
By transferring the containers 1 from the conveyor 2 to the conveyor 3, a required gap can be formed between the containers 1.

At the front side of the conveyor 3, as shown in FIG.
and a detector 5 for detecting the presence or absence of the container 1. When the detector 5 detects the container 1, air is injected from the air nozzle 4, and the container 1 is transferred to the chute 6 provided on the side of the conveyor 3. It is designed to be pushed inward.

The containers 1 pushed out into the chute 6 fall inside the chute 6 due to their own weight in an overturned state, and are stored in the chute 6 in a state where they are overturned and in contact with each other. These containers 1 can be taken out one by one through an opening 7 provided at the bottom of the chute 6, as described below.

In FIGS. 1 and 2, numeral 10 denotes a conveying means for rotatably transporting the container 1 in an overturned state;
This conveyance means 10 is equipped with a rotary table 12 that is rotationally driven by a drive shaft 11, and a container storage section 13 consisting of slits formed at equal intervals in this first rotary table 12. At the bottom of 12 is a support member 1 fixed to the machine frame 14.
5 are arranged over the required rotation range.

As shown in FIG. 2, the opening 7 of the chute 6 is opened at a position above the container storage section 13, which is moved as the rotary table 12 rotates, and the opening 7 is located above the upper surface of the support member 15. Container storage part 1
3 so that the height difference with the top surface of the container 1 is slightly larger than the diameter of the container 1, and from the chute 6 to each container storage section 13 with the bottom of the container 1 facing inward in the radial direction. We are trying to supply one at a time.

At this time, the supporting member 15 supports the lower surface of the container 1 supplied in the container storage section 13 to prevent the container 1 from falling downward, and
A closing plate 16 is provided between each adjacent container storage part 13, and the closing plate 16 prevents the container 1 following the container 1 supplied from the chute 6 to the container storage part 13 from falling.
This can be prevented.

Furthermore, the support member 15 further includes a container storage section 1.
While fixing guide members 17 and 18 that support and guide the bottom and top of the container 1 housed in the container 3,
As shown by the dotted line in FIG.
At the portion 9, only the top side of the container 1 can be supported.

Therefore, the container 1 stored in the container storage section 13 of the rotary table 12 through the opening 7 of the chute 6 is guided by the support member 15 and the pair of guide members 17 and 18 while being guided by the rotary table 1.
It comes to be conveyed on the circumference along with the rotation of 2. When the container 1 reaches the notch 19 provided in the support member 15, the support member 15 supports only the top side of the container 1 and releases the support on the bottom side of the container 1, as shown in FIG. As shown by the line,
The container 1 rotates and falls with the bottom side facing downward.

By the way, below the rotary table 12,
A transfer means 25 is provided for transferring the holder 24 that fits and supports the bottom of the container 1. The transfer means 25 includes a second rotary table 26 that rotates together with the rotary table 12, and a second rotary table 26 that rotates together with the rotary table 12.
6, and a semicircular pocket 28 (holder holding part) for storing the holder 24 formed on the outer periphery of the support member 27 located directly below each of the container storage parts 13. There is.
The holder 24 is attached to the conveyor 2 shown in FIG.
9 in a continuous line, and the timing wheel 30 rotates the rotary tables 12, 26.
After being synchronized with the data, it is sequentially supplied into each of the pockets 28 via the star wheel 31 on the supply side.

Further, as shown in FIG. 1, containers 1 are placed at the lower part of the upper rotary table 12 and the upper part of the lower rotary table 26, respectively, through the notches 19, so that the containers 1 are rotated and dropped so that the bottom faces downward. Hold the holder 2 in an almost upright position.
Guide members 32 and 33 are provided to guide the inside of the vehicle.

The upper guide member 32 is formed in a cylindrical shape,
The upper part is formed in an elliptical shape radially inward with a large diameter to allow the container 1 to rotate and fall, while the lower part has a reduced diameter so that the container 1 can stop rotating and be guided vertically downward. has been done. On the other hand, the lower guide member 33 guides the container 1 from the upper guide member 32 and at the same time allows the container 1 stored in the holder 24 to be carried out from the pocket 28 together with the holder 24. The cylindrical body has a semicircular cross-section with its radially outer side open.

Therefore, the container 1 that falls while rotating due to the notch 19 with the bottom facing downward is stopped from rotating by the guide member 32 in the middle of falling, is made to stand upright, and is further transferred to the guide member 33. The bottom portion thereof becomes a drop fit into the holder 24.

Next, the holder 2 into which the bottom of the container 1 is fitted
As shown in FIG.
It is equipped with a pair of upper and lower wheels 37 and 38 that are rotationally driven in synchronization with wheels 2 and 26, and the upper wheel 37 has pockets 39 that support the body of the container 1 at equal intervals, and the lower wheel 38 has pockets 39 that support the body of the container 1. A pocket 40 for supporting the holder 24 is formed directly below the pocket 39.

A rotating body 41 that supports the wheels 37 and 38
has the same number of lifting rods 4 as each pocket 39, 40 above.
A cam follower 43 provided at the bottom thereof is rotatably engaged with a cam 44 fixed to the machine frame 14, and the elevating rod 42 is raised and lowered by the cam 44. We are making it possible to do so. A weight 45 is attached to the upper end of each lifting rod 42, and a push-down member 46 is attached to push down the top of the container 1 housed in the holder 24 by the weight of the weight 45. A bracket 47 is attached to each elevating rod 42 to prevent its rotation, and the bracket 47 is engaged with a rod 48 erected on the rotating body 41 so as to be able to rise and fall.

The push-down member 46 is located above when the holder 24 into which the bottom of the container 1 is fitted is conveyed by the pocket 28 of the support member 27 and approaches the star wheel 35, The assembled holder 24 is placed in the pocket 40 of the wheel 38.
Also, the containers 1 are delivered to the pockets 39 of the wheels 37, respectively.

Container 1 and holder 24 are connected to star wheel 35
When the container 1 is delivered and transported, the push-down member 46 is lowered by the cam 44, and the bottom of the container 1 is completely fitted into the holder 24 by the weight of the weight 45. When the push-down member 46 is raised again by the cam 44, the holder 24 with the bottom of the container 1 completely fitted therein is discharged onto the discharge conveyor 49 shown in FIG.

"Effects of the Invention" As described above, according to the present invention, it is possible to drop a container while rotating it in a plane perpendicular to the direction in which the container is conveyed by the rotary table, that is, in a vertical plane in the radial direction of the rotary table. Therefore, even if the rotational speed of the rotary table fluctuates, there is no significant effect on the dropping of containers, and therefore, containers can be dropped in a constant state even during high-speed operation.

Since the container storage section, guide member, and holder holding section are provided on the rotary table, their relative positions do not change, and the container can always be dropped in a constant state, which also makes maintenance easier. This provides the effect that the container can be reliably dropped into the holder for a long period of time.
