Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container conveyance device that includes a walking beam type conveyance mechanism and an input conveyor mechanism for feeding objects to the walking beam type conveyance mechanism.

In conventionally known container conveyance devices of this kind, the walking beam type conveyance mechanism and the carry-in conveyor mechanism are operated asynchronously, and the carry-in conveyor mechanism continuously feeds the articles to be conveyed.

However, as is conventionally known, and as will be described later, the walking beam type transport mechanism does not transport the transported object continuously at a constant speed, but rather intermittently, so it is difficult to transport the transported object between the two mechanisms. Objects were accumulating and the conveyor mechanism was putting a lot of pressure on the objects being transported.

If the objects to be transported collide with each other due to the pressure, there is no problem if there is no risk of damage, but for example, in the case of large bottles whose outer peripheries are coated with resin, etc., the coating may be damaged by collisions between the bottles. The problem arises that it is damaged.

Therefore, the purpose of the present invention is to suppress the pressure on the conveyed items to the minimum necessary to carry them into the walking beam type conveyance mechanism, and for this purpose, the carry-in conveyor mechanism is synchronized with the walking beam type conveyance mechanism. It is designed to be driven intermittently.

The invention will now be described with reference to the illustrated embodiments.

In FIG. 1, A is a carry-in conveyor mechanism, B is a walking beam type conveyor mechanism, and C is a discharge conveyor mechanism.The conveyed object is conveyed in order of the carry-in conveyor mechanism A, the walking beam type conveyor mechanism B, and the discharge conveyor mechanism C.

FIG. 2 is a schematic side view showing the above-mentioned walking beam type conveyance mechanism B.
A bed 2 and a second bed 3 are arranged in parallel, and a plurality of trusses 4 and 5 are hung between the left and right pair of first beds 2 and between the left and right pair of second beds 3, respectively. It has been passed.

A plurality of first beams 6 are installed between the plurality of trusses 4 provided on the first bed 2, and are arranged parallel to the bed 2 with a fixed interval between them. A second beam 7 is similarly attached between the trusses 5 of the second bed 3.

At this time, the second beams 7 are provided so as to be located between the first beams 6, respectively.

The first and second beds 2 and 3 are each supported by a roller 10 at the tip of a Y-shaped arm 9 that can swing around a shaft 8, and an elevating cylinder device 11 is linked to the Y-shaped arm 9. has been done.

Therefore, if the rod 12 of the cylinder device 11 is moved back and forth to swing the Y-shaped arm 9, the first and second beds 2
, 3, ie the second beam 6.7, can be raised and lowered in opposite directions.

It goes without saying that when the first and second beds 2 and 3 are raised and lowered, care must be taken so that the trusses 4 and 5 and the beams 6 and 7 provided thereon do not interfere with each other and impede the raising and lowering of the beds.

Furthermore, a reciprocating cylinder device 13 that reciprocates the eleventh and second beds 2 and 3 in opposite directions on the roller 10 is linked via a link mechanism 14.

This link mechanism 14 converts the reciprocating motion of the rod 15 of the reciprocating cylinder device 13 into first and second reciprocating motions in opposite directions.
Needless to say, the transmission can be transmitted to the first and second beds 2 and 3, and the structure is such that it can simultaneously allow the first and second beds 2 and 3 to be raised and lowered.

Therefore, in order to transport the transported object 1 in the direction of the arrow in FIG. When the rod 12 of the device 11 is moved to the left end of movement, the second beam 7 descends and the first beam 6 rises, so that the conveyed object 6 is moved by the first beam 6.
will be supported by

Next, when the rod 15 of the reciprocating cylinder device 13 is moved upward, the first beam 6 and the conveyed object 1 supported by it are moved in the direction of the arrow, and at the same time the second beam 7 is moved in the opposite direction. do.

Then, the lifting cylinder device 11 is operated again, and the rod 12 of the reciprocating cylinder 13 is moved in the opposite direction to support the conveyed object 1 by the second beam 7.
If it is moved in the opposite direction to the above, the second beam 7 and the conveyed object 1 are moved in the direction of the arrow.

Since this results in the first state shown in the figure, the objects 1 can be sequentially transported in the direction of the arrow by controlling the operation of each cylinder device 11, 13 in a fixed order.

The operation of the cylinder devices 11 and 13 is controlled by, for example, operating a switching valve (not shown) by the rod 12 when the rod 12 of the lifting cylinder device 11 moves to one sliding end, thereby switching the reciprocating cylinder. At the same time as stopping the operation of the device 11, pressure fluid is supplied to the reciprocating cylinder device 13 to operate it, and further, the reciprocating cylinder device 13 is activated.
When the rod 15 moves from one sliding end to the other sliding end, the switching valve is switched in the same manner as above,
I was trying to get the cycle mentioned above.

Therefore, in this embodiment, the rod 1 of the reciprocating cylinder device 13 is
A pair of detection switches 16 and 17 detect both sliding ends of 5.
, and both detection switches 16 and 17 are connected in series to the prime mover (not shown) of the carrying-in conveyor mechanism A.

For both detection switches 16 and 17, the protrusion 18 provided on the rod 15 is connected to the detector 16a of each detection switch 16, 17.
It has the function of opening the contact only when it is in contact with the rain detector 17a, and therefore, the conveyed object 1 is moved forward only when the protrusion 18 is away from the rain detectors 16a and 17a, that is, by the operation of the reciprocating cylinder device 13. The prime mover of the carrying-in conveyor mechanism A is energized only when the carrying-in conveyor mechanism A is in use, and thereby the carrying-in conveyor mechanism A is driven intermittently in synchronization with the walking beam type conveying mechanism B.

Note that the carry-out conveyor mechanism C is asynchronously operated with the two mechanisms A and B and is operated continuously.

Further, the means for synchronizing the carry-in conveyor mechanism A and the walking beam type conveyance mechanism B is not limited to that of the above embodiment, and phototube switches may be used in place of the detection switches 16 and 17. It is also possible to use the pressure of the pressurized fluid to the cylinder device 13.

As mentioned above, in the present invention, the loading conveyor mechanism is synchronized with the walking beam type conveyance mechanism and operated intermittently, so it is possible to suppress the pressure applied to the conveyed items to the minimum necessary amount, and therefore the conveyed items The effect is that damage caused by mutual collision can be minimized.
