Description

Description: TECHNICAL FIELD The present invention relates to a device for automatically opening cans and automatically draining canned beer, canned juice, and the like that are not suitable for the enclosed liquid amount. .

[Conventional technology]

For canned beer, canned juice, etc., container supply-liquid injection-capping-check for liquid entry lines (X-ray irradiation, weight measurement, etc.)
-Manufactured by a series of processes consisting of product removal.

Then, in the liquid spill line checking step, the unqualified products which are in excess or deficiency with respect to the specified amount are sent to the transfer line branched from the check step, and the lid is opened and the liquid is drained in the transfer line.

Thus, in this opening and draining, conventionally, a cap-shaped cap capped in a glass bottle or a synthetic resin container is automatically pulled up and removed, and then the liquid is automatically sucked up. The device (Japanese Patent Publication No. 48-40691) and the screw-type screw cap sealed in the bottle or container (in the case of draft beer or gas drink of carbonated drink under pressure) are automatically twisted and then removed. There is a lid opening / draining device (Japanese Patent Publication No. 61-35077) that automatically sucks liquid.

[Problems to be Solved by the Invention]

Since the conventional automatic lid opening / draining device is intended for a glass bottle or a synthetic resin container with a crown cap or a screw cap sealed, in particular, the automatic lid opening means is safe. However, it cannot be applied to the can-enclosed automatic can opening of canned beer, canned juice, etc., which has dominated the market in recent years from the viewpoints of measuring measures and prevention of deterioration of the enclosed liquid, and therefore the can opening work is manual. The current situation is that

Therefore, there is a problem that the work efficiency of opening the can is poor and labor saving cannot be achieved.

The present invention focuses on the above-mentioned problems of the prior art, canned beer,
An object of the present invention is to provide an opened can of unqualified products such as canned juice such as a can-filled type, and an automatic device for draining the can.

[Means for Solving the Problems]

According to the present invention, a turntable that intermittently rotates via an indexing mechanism, a chuck opening / closing / rotating mechanism provided on the turntable, and a size of the can are divided into a large group and a small group. Equipped with a plurality of can-opening cutters whose positions can be set variably and an air blowing mechanism for bubble cutting, opening and closing the chuck of the cans transferred to the transfer line.
It is characterized in that the turntable is sequentially intermittently rotated to a position where it is gripped by a rotation mechanism, a can opening position of a cutter, an inverted liquid draining / foaming position of a can, an inverted return of the can and a grip open position. .

〔Example〕

An embodiment of the present invention will be described for canned beer with reference to the drawings.

As shown in FIG. 1, the automatic can opener / drainage device A uses the transport mechanism B for the unqualified cans 1 and the indexing mechanism C to move the
A turntable 2 which rotates intermittently to a degree, and a pair of chucks 3 which perform each operation of gripping, inversion, and inverted gripping and releasing of the can 1 by a chuck opening / closing / rotation mechanism D attached to the turntable 2. It is composed of a cutter 4 for opening a can, a drainage receiver 5, an air blowing mechanism F for removing bubbles, and a can receiver 6.

Therefore, the chuck opening / closing / rotating mechanism D is set at the rotating position of the turntable 2 which is intermittently rotated by the indexing mechanism C.
The pair of chucks 3 closed by the operation of gripping the can 1 which has transferred the transport mechanism B, then actuates to the rotational position b, and is lowered by the cutter drive mechanism E operating at the rotational position b to open the can. 4, the can 1 is opened, then the can 1 is tilted by the chuck 3 that is rotated by the chuck opening / closing / rotating mechanism D that operates when the rotating position B is passed, and draining is started.
At the turning position c, the liquid is completely inverted to complete the drainage (stored in the drainage receiver 5) and the air blowing mechanism F
The air is blown into the can 1 by the operation of
Next, the chuck opening / closing / rotating mechanism D, which operates at the time when the turning position c has passed, starts to restore the inverted state of the can 1 by the chuck 3 that rotates in the reverse direction, and opens the chuck 3 at the completely restored rotating position d. The can 1 is sent into the can receiver 6.

Thus, operation of the chuck opening / closing / rotating mechanism D (grip of the can 1) at the rotating position a of the turntable 2, operation of the cutter driving mechanism E at the rotating position b (operation of the cutter 4), rotating position Opening and closing the chuck from B to the rotating position
Operation of the rotating mechanism D (draining operation), operation of the air blowing mechanism F at the rotating position c (bubble cutting operation), operation of the chuck opening / closing / rotating mechanism D from the rotating position c to the rotating position d ( The operation of returning the can 1 to the inverted position) and the operation of the mechanism D at the same position d (holding and releasing the can 1) are performed by the position detection sensors (phototube, limit switch, etc.) respectively provided at the turning positions.
Controlled by.

Next, the transport mechanism B, the indexing mechanism C, the chuck opening / closing / rotating mechanism D, the cutter driving mechanism E, and the air blowing mechanism F will be described.

As shown in FIG. 1, the transport mechanism B includes two pairs of air-operated stoppers 8a and 8b, which are orthogonal to the height direction of the can 1 and are paired at the end point of the transport path 7 of the can 1. When the stopper 8a is retracted, the preceding can 1 is sent to the chuck 3, and the stopper 8b moves forward and the stopper 8b retracts so that the succeeding can 1 comes into contact with the stopper 8a and waits, and then the stopper 8b advances. Can be followed by 1
Is controlled to prevent the migration of.

As shown in FIG. 2, the indexing mechanism C slides on the input side roller gear cam 9 having a cam portion 9a having a predetermined curve and a linear portion 9b, and the cam portion 9a and the linear portion 9b. The roller gear 10 is composed of an output side roller gear 10 having a plurality of cam followers 10a, and the roller gear 10 rotates intermittently by 90 ° with respect to a roller gear cam 9 which rotates at a constant speed.

Therefore, the roller gear 10 of the indexing mechanism C is
The turntable 2 connected to is rotated by 90 ° intermittently.

The indexing of the intermittent rotation is set to the time required for liquid removal and bubble removal from the rotation position B of the turntable 2 at C. The indexing mechanism is not only the above-mentioned means but also the Geneva mechanism and the intermittent gear device. Intermittent exercise devices such as

As shown in FIG. 3, the chuck opening / closing / rotating mechanism D includes a pair of chucks 3 having bases that slide on guide bodies 11a provided on the chuck body 11, and a bent portion pivotally supported on the chuck body 11. The pair of L-shaped levers 13, one end of which is fitted into a recess 3a formed in the base of the chuck 3 and the other end of which is fitted into a recess 12a formed at the end of a rod 12 which penetrates the chuck body 11, and the rod 12 A cylinder 15 having a pair of ports 15a for accommodating a piston 14 provided at the other end of the
And a gear 17 fixed to the other end of a shaft 16 having one end fixed to the cylinder 15 and an air-operated rack 18 meshing with the gear 17.

Therefore, the L-shaped lever 13 is swung by the up-and-down movement of the rod 12 associated with the feeding and discharging of air into the cylinder 15, and the chuck 3 slides the guide body 11a to grip and open the can 1.

Further, the linear motion of the rack 18 due to the air operation is converted into the rotary motion of the gear 17, and the chuck body 11 rotates forward and backward through the shaft 16, and the can 1 gripped by the chuck 3 is inverted and inverted.

Since the chuck 3 is operated by air, the diameter of the can differs depending on the capacity of the canned beer (83.4 mmφ at 1000 cc, 75 mm
76mmφ at 0cc, 67mmφ at 500cc, 350cc
65mmφ, 250cc 62mmφ, 135cc 54
surely grip the can 1 according to mmφ).

As shown in FIG. 4, the cutter drive mechanism E has different can diameters and different can heights as described above depending on the capacity of can beer (204.5 mm at 1000 cc, 185.7 mm at 750 cc, 500 cc). 167mm, 350cc 1
23 mm, 250 cc 92 mm, 135 cc 80 mm), so that body parts 4a ₁ and 4b _{1 of} two different diameters (56 mmφ and 40 mmφ) with 750 cc or more as a large group and 500 cc or less as a small group, and the body part 4a ₁ , 4b ₁ is provided with cutters 4a and 4b each having a quadrangular pyramid-shaped blade portion 4a ₂ and 4b _2, and a support 1 for each of the cutters 4a and 4b is provided.
A large / small group switching cylinder 22 for air operation is attached to a frame 21 supporting 9 and 20, and the height of air operation is set so that the can opening stroke of each cutter 4a, 4b is about 30 mm. Cylinder 2
3, 24 are attached.

Thus, the large / small group switching cylinder 22 and the height switching cylinders 23, 24 are controlled by a sensor that detects a slide range in which the chuck 3 of the chuck opening / closing / rotating mechanism D grips the can 1.

Therefore, the cutters 4a and 4b are switched by the large and small groups of the cans 1 that have moved to the rotation position b of the turntable 2, and the heights facing the cans 1 are switched, and the blade portion 4a ₂ is opened by the can opening stroke of about 30 mm. Alternatively, the can is opened with 4b ₂ .

In addition, at a rotation position B of the turntable 2, a table 25 that comes into contact with the bottom of the can 1 is installed so as to be vertically slidable.

The air blowing mechanism F is not shown in the drawing, but is not shown in the turntable 2
A timer is activated by a sensor that detects the time when is rotated to the rotating position c, and air is blown into the can 1 from the nozzle for a set time to perform bubble cutting.

As described above, the present embodiment shows the automatic can opener / drainage device for canned beer, but it is clear that it can be applied to the treatment of unqualified canned juice.

[Effect]

According to the present invention, a chuck opening / closing / rotating mechanism is attached to a turntable which intermittently rotates via an indexing mechanism, and a can held by the chuck opening / closing / rotating mechanism is opened by a cutter, and liquid is removed by inversion of the can. It is designed to rotate sequentially to each position of foam cutting and gripping and opening of cans, which can smoothly and quickly perform automatic can opening of unqualified products such as can beer and can juice, and automatic draining, It can be omitted.

Further, since the can opening cutter is provided with two types divided into large and small groups according to the size of the can, the can opening operation can be reliably performed according to the difference in the can size.
