Abstract

PURPOSE:To orderly align flow of containers from plural rows to a single row by forming a combiner part on a curved travelling passage inclined into downward slope on the maximum speed side of a slat chain. CONSTITUTION:At transferring containers 1 from a supply conveyor 2 to a combiner part 3, they are transferred in order to the outside slat chain having a higher speed by descending on downward slope and by the function of a guide 5, and spaces between them are spread. At passing through a half of a semicircular part, they are transported in the opposite direction against the down slope, transferred to the more outside slat chain having more higher speed by function of the guide 5, as 3a - 3e, and mutual spaces among the containers are further spread. Finally, a single row of spacedly arranged containers is formed and transported to a discharge conveyor 4.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a conveyor device for conveying q containers such as bottles and cans in food plants, cosmetic plants, and the like.

(Prior art) This type of device uses a drive motor (107) as shown in FIG.
a supply conveyor (102) in which a plurality of rows of slat chains driven by a slat chain are arranged in parallel, and a combiner section in which a plurality of rows of slat chains connected in a partially wrapped state around the supply conveyor (102) are sequentially arranged in parallel at increased speeds. (103) and a single-row discharge conveyor (104) connected to the highest speed slot chain of the combiner section (103). ) and roller chain (110), the slat chain is (103a) (103b) (103c)
The speed of the slat chain is increased in the order of (103d) and (103e), and guides (105) and (106) are provided on both sides of the upper surface of the conveyor to guide the container (101). The containers (101) supplied in double rows to the combiner section (103) are controlled by the speed difference of the slat chains that increase their speed sequentially and the guides (105) (106) whose downstream side is narrowed sequentially.
), the containers (101) are arranged sequentially from double rows to single rows.

(Problem to be Solved by the Invention) However, since the guides (105 and 106) that guide the container (101) from both sides have a wedge shape that narrows at the downstream end, there is a certain probability that the container will become clogged as shown in Figure 5. Occur.

Also, the container (101b) that overturned from upstream is a normal container (101b).
101), almost 100% clogging occurs as shown in Figure 6.

If a container becomes clogged in the combiner section, there is a problem in that the clog must be cleared manually to restore normal conditions.

Further, since the guides (105) and (106) are wedge-shaped, the contact pressure between the containers in the combiner section increases due to the pressure of the containers from upstream, and the problem of damage to the container surface and generation of noise cannot be ignored.

The above problem should be solved (as a means, JP-A-56-1612
There are those described in Publication No. 16 and Japanese Patent Application Laid-open No. 135025/1983. This increases the speed of multiple rows of slat chains corresponding to the combiner section in stages,
In addition, the entire combiner section is tilted in cross section, containers are separated from each other by the action of a guide, and overturned containers are discharged from the combiner section using the tilt, which solves the above problem. Therefore, it is necessary to eliminate the difference in level between the supply and discharge side conveyors, which are not inclined.

In other words, in order to eliminate the difference in level, some of the connectors had to have a slightly twisted structure to match the slope, making assembly and adjustment difficult and increasing costs.

The present invention has been proposed in view of the current situation, and an object of the present invention is to eliminate the level difference in the connecting portion of the combiner portion.

(Means for Solving the Problems) The structure of the present invention for achieving the above object will be explained using FIGS. 1 to 3 corresponding to the embodiments. Multiple rows of slat chains (3a) (3b) partially wrapped around the supply conveyor (2)
A combiner section (3) in which the speeds of... are sequentially increased and installed in parallel, and a discharge conyer (4) provided downstream of the combiner section (3).
In the container conveyor device, the combiner section (3) is formed into a curved running path that slopes downward toward the highest speed side of the slot chain.

(Function) According to the present invention, the double-row slat chain curved by the above-mentioned means can process containers smoothly and orderly from the 3rd row to the 2nd row and from the 2nd row to the 1st row. Since the container is tilted downward toward the slat chain, an overturned container easily slips and heligates out of the slat chain.

(Example) An example of the present invention will be described below based on the drawings.
As shown in the figure, double-row slat chains are installed in parallel, and the motor (
A supply conveyor (2) driven by force, a combiner section (3) consisting of a curved slat chain partially wrapped around the conveyor (2), and a combiner section (3) arranged downstream of the combiner section (3). The combiner section (3) consists of a double-row curved slat chain (
3a), (3b), (3c), (3d) and (3e) are installed in parallel, and the chain speed of each slat chain is controlled by independent motors (8a), (8b), (8c), (8d) and (8e).
), each chain speed differs. The semicircularly curved combiner part (3) is sloped downward toward the highest speed slat chain (3e), and the pedestal α2 for receiving the overturned container (1b) on the outer periphery is lower than the top surface of the combiner part (3). The inner guide (5) (61 is provided on both sides, but the inner guide (5) is installed at the level to guide the container (1).
), and has a shape that guides the containers (11) sequentially from the inside to the outside, and the mating guide (6) is not provided in the combiner part (3).

The supply conveyor (2) uses a motor (7) as a drive source, and the discharge conveyor (4) uses a motor (9) as a drive source.

Next, the sensor detects the containers (1) in each part of the combiner section (3).
), (10a) (10b) (1
0c), and the speed of the upstream supply conveyor (2) is controlled by a control device (not shown). In addition, the sensor sensor detects the amount of accumulation in the downstream container and controls the speed of the upstream supply conveyor (2).

The speed of the slut chains (3a) to (3e) is greater than the difference in their semicircularly curved shapes (3a), (ab)s (3c)-
(ad) and (3e) are farthest away in that order. In other words, the speed gradually increases on the outside of the curved part.

The container (1) is transferred from the supply conyer (2) to the combiner section (3).
), it descends down the slope, and by the action of the guide (5), it sequentially transfers to the faster outer slat chain and widens the gap between them. After passing half of the semicircular shape, it is transported in an upward direction, contrary to the downward slope, and is guided (
5) transfers to the outer slat chain, which has a faster speed, further widens the gap between containers (1), and finally the first
As shown in the figure, the discharge condenser is a single row with a gap between the containers.
(4).

In the above embodiments, the shape of the combiner portion (3) has been described as having a circularly curved shape with a downward slope in the outer circumferential direction, but a combiner having an upward slope in the outer circumferential direction is also conceivable.

In this case, contrary to the first embodiment, the speed of each slot chain is increased sequentially toward the inner circumference, and the arrangement of the guides is also narrowed from the outer circumference to the inner circumference. A pedestal for receiving an overturned container is also arranged on the inner periphery.

Although the curved portion has been described as being semicircular, it is not limited to a semicircular shape, and may be shaped to match the arrangement required as a container conveyance device.

(Effects of the Invention) According to the present invention, by applying curve pressure to the combiner section, the flow of containers is arranged in an orderly manner from double rows to single rows, and the conveyor structure in which the combiner section is sloped remains the same. This makes it possible to easily adjust the tilt angle.

In addition, by tilting the combiner section, the overturned container is helijected to the outside, which eliminates the problem of container clogging.Furthermore, by installing sensors inside the combiner section and downstream, the containers can be opened and closed electrically. Since the view can be kept constant, the pressure in the container can be significantly lowered, preventing damage to the container, reducing noise, and making it possible to match the layout required for the container conveyance device, giving greater freedom in design. It has the effect of increasing
