Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lid hook device for placing a lid on a storage box storing small parts such as spring washers.

[Conventional technology and its problems]

Storage boxes for storing small parts such as springs and washers are usually made of cardboard, etc., and are not very structurally strong, so if you fill them with small parts, it will be difficult to store them due to the weight of the parts. The side walls of the box bend and are pushed outward.

Such expanded side walls are a major hindrance when automatically fitting the lid onto the storage box, and conventionally, the work of fitting the lid onto the storage box has been done manually. For this reason, it took time and effort to fit the lid on, resulting in poor work efficiency.

[Purpose of the invention]

This il was created in consideration of the above points, and the lid hook is a device that can automatically and reliably fit the lid into a storage box filled with small parts and whose side walls expand outward. is intended to provide.

[Means for solving problems]

In order to solve the above problems, according to the present invention, a guide in which a plurality of vertical elastic plates are arranged in an annular manner is provided on the storage box mounting table, and the storage box passing path inside the guide is directed upward. a lid feeding mechanism for covering the upper opening of the guide with a lid, the upper opening of the passage being made smaller than the outer periphery of the storage box; A lifting mechanism was installed to raise it.

[Effect]

In the device, the lid hook configured as described above is used to raise the storage box by pushing up the mounting table using the elevating mechanism, and a guide is formed upward, which serves as a passageway, gradually narrowing so that the upper opening is smaller than the outer periphery of the storage box. is placed, so the storage box will elastically push out the guide and rise.
Conversely, the elastic force of the guide pushes the side wall inward and deforms so that the outer circumference becomes smaller. At this time, the top opening of the guide is covered with a lid by the lid supply mechanism, and when the shrinkable box whose outer periphery has been deformed to a small size rises and passes through the top opening, it enters the inside of the lid and closes the lid. The lid is then fitted with the lid.

[Embodiments] Examples according to the present invention will be described below based on the accompanying drawings.

As shown in FIGS. 1 and 2, an upper table 1 and a lower table 2 are mounted in parallel, and openings 1a and 2a are formed in the center of each.

Among these, the opening 1a of the upper table 1 is formed to be larger than the outer periphery of the lid B, and the opening 2a of the lower table 2 is formed to be slightly larger than the outer periphery to the storage box.

On the other hand, a conveyor 5 for transporting storage boxes is attached to one side of the lower table 2, and as shown in FIG. 3, storage boxes filled with small parts are transported to a stop plate 5.
When it hits point a and stops, it is pushed out to the lower table 2 by the storage box pusher 6. In this case, a guide plate 9 is attached to the carry-in side of the lower table 2, so that the storage box A is guided to the opening 2a.

A mounting table 3 is located inside this opening 2a, and supports the storage box A. This mounting table 3 is
The elevating mechanism is connected to the above and moves up and down, and when rising, it pushes up the storage box A through the opening 1a of the upper table 1.

On the other hand, a shutter opening/closing mechanism 11 is provided on one side of the upper table 1, and the opening 1a is opened and closed by two shutter plates 12 and 12.

This shutter plate 12.12, as shown in FIG.
It is slidably mounted along both walls of the opening 1a and is connected via a pair of links 17.17 to a reciprocating plate 16 connected to an actuating cylinder 15.

When this reciprocating plate 16 is pushed out by the actuating cylinder 15 and moves forward toward the upper table 1, the tips of both links 17.17 move away from each other, and both shutter plates 12.12 move left and right. It will be opened in Conversely, when the reciprocating plate 1G is retracted, the shutter plate 12.12 will be closed.

As shown in FIG. 4, on the side of the upper table 1 opposite to the shutter opening/closing mechanism 11, there is a conveyor 7 for conveying the lid B.
is provided, and when the lid B is conveyed and stops against the stop plate 7a, it is pushed out to the upper table 1 by the lid pusher 8, and a guide plate 10a that is attached to the loading side is provided.
, 10'b into the opening 1a and fed onto the upper surface of the closed shutter plate 12.12.

Also, between the lower table 2 and the upper table 1, there is a sixth
As shown in the figure, a guide plate 13 whose upper end is inclined toward the center of the opening 2a is attached to surround the opening 2a of the lower table 2 from three sides.

Further, a guide plate 14 is attached to the receiving plate 6a of the storage box pusher 6 with its upper end inclined in the direction of pushing out the storage box A, and the pusher 6 pushes out the storage box A until the receiving plate 6b reaches the opening 2a. When I pushed out the 13 and 14 moths,
The opening 2a is surrounded by the side plate from four directions. This receiving plate 6a remains at the periphery of the opening 2a even after the storage box A is pushed out into the opening 2a, and the above state is maintained until the mounting table 3 rises and reaches the upper limit of the upward stroke. .

Guide plate 13.1 surrounding opening 2a in this way
The upper opening 18 formed at the upper end of the storage box A is set to be narrower than the outer periphery of the storage box A, and larger than the outer periphery of the force fighting table 3 so that the lifting and lowering of the placing table 3 is not hindered.

Therefore, when the storage box A is pushed up, the side walls of the storage box A and the inner surfaces of the guide plates 13 and 14 interfere with each other, causing the storage box A to
The guide plates 13, 14 rise to spread out, and conversely, the side walls are pushed inward by the repulsive force of the guide plates 13, 14, deforming the entire structure to become smaller.

In order to obtain the above-mentioned effect, the guide plates 13, 14 are made of a material with appropriate elasticity, for example, a plate material such as metal or flexible synthetic resin.

In addition, a protrusion 13a is provided on the outside of the upper end of each of the 13 guide plates, and when the shutter plate 12.12 is opened, the lid B falls and is supported on the protrusion 13a. .

On the other hand, above the upper table 1, a mold pressing mechanism 19 is installed. This pressing mechanism 19 is configured such that the mounting table 3 and the storage box A are pushed up by the lifting mechanism 4, and the storage box A is pushed up by the lid B.
When it is inserted through the opening 1a with the top covered with it and lifted up,
The lid B is pressed from above to ensure that the storage boxes A and iB are fitted together. Furthermore, a conveyor 20 is provided between the upper table 1 and the mold pressing mechanism 19, which carries out the storage box A fitted with the lid B when the mounting table 3 reaches the upper limit of its upward stroke and stops. A pushing mechanism 21 for pushing out the storage box onto the conveyor 20 is attached at the position.

Next, the effects will be explained in order.

First, the lid B is carried in by the conveyor 7 and pushed out to the opening 1a of the upper table 1 by the lid pusher 8.
The top surface of both shutter plates 12.12 is supplied. on the other hand,
After the storage box A is filled with small parts, it is carried in by the conveyor 5, pushed out to the opening 2a of the lower table 2 by the storage box pusher 6, and supported on the upper part of the mounting table 3.

(See Figure 6) Next, the shutter plate 12.12 of the opening 1a opens, the lid B falls through the gap, and the protrusion 1 on the upper part of the guide plate 13
3a, in this case the shutter plate 12.
12 opens in both directions, the ground surface of the lid B is not dragged to one side, and the lid B falls almost straight onto the protrusion 13a without tilting.

After that, the mounting table 3 is pushed up by the elevator 4 and the storage box A
rises. At this time, since the upper passage of the storage box A is narrowed by the guide plate 13.14, the storage box A expands the guide plate 13.14 and rises. The repulsive elastic force presses the peripheral wall from four directions and deforms the outer peripheral shape to become smaller. and an upper opening 1 formed at the upper end of the guide plate 13.14.
When the storage box A rises to δ, as shown in FIG. 7, since the outside of the upper opening 18 is covered with the lid B in advance, the storage box A enters the inside of the lid B from the upper opening 18. At this time, the outside of the upper opening 18 is expanded outward by the storage box A and the lid B
Since the inner periphery of the storage box A is pushed and expanded from the inside, it becomes easier to enter the lid B of the storage box A, and the storage box A and the lid B are reliably fitted together.

In this case, the elastic force of the guide plates 13 and 14 acts on the side walls obliquely from above, so the storage box is deformed so that the upper entrance becomes narrower, and the small parts packed inside are This effectively prevents protrusion.

Meanwhile, the lifting mechanism 4 continues to operate, pushing the storage box A fitted with the lid B upward through the guide plate 13, 14 and the opening 1a of the upper table 1. At this time, as shown in FIG. 8, the mold pressing mechanism 19 acts from above and presses the lid B with the elastic force of the spring that becomes stronger as the storage box A rises, thereby ensuring that the lid B and the storage box A fit together. Make it even more reliable.

When the lifting mechanism 4 reaches the upper limit of its operating stroke and stops pushing up, the pushing tool of the pushing mechanism 21 moves from the side to push the covered storage box onto the conveyor 20. This conveyor 20 transports the storage box to the outside.

Thereafter, when the mounting table 3 is lowered and returned to the rear end position, the shutter plates 12, 12 are closed, the storage box pusher 6 is retreated and returned to the initial state, and the above-described operation is repeated.

[Effects] As described above, the present invention provides a guide in which a storage box filled with small parts and whose side walls are expanded is pushed upward by an elevating mechanism, and the upper opening is smaller than the outer periphery of the storage box on the passage path. By providing a guide, the peripheral wall is elastically pressed and moved inward, and the upper opening of the guide is fitted with the lid supplied from the lid supply mechanism, making it possible to automate the loading of the lid onto the storage box. , realize highly efficient work.

In addition, the guides are arranged so that the passage of the storage box gradually narrows, and the pressure from the guide acts diagonally from above on the side walls of the storage box as the storage box rises, making the storage box smaller from the population side. As a result, the small parts filled inside are prevented from flying out, and the lid can be securely attached.
