Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to improvements in a method for feeding molding machine material and an apparatus for carrying out this method.

[Background technology]

Air transportation using pipes is common for supplying materials to molding machines, but when using air transportation using such pipes, not only do pipes and hoses complicate the work site (at least 2 times the amount of air and material (If multiple materials need to be mixed, a corresponding number of pipes will be required for each molding machine). Due to the power source used for this purpose, the influence of noise cannot be ignored, and there are also problems on the work site, such as the need for work space.Furthermore, when the length of the pipe hose becomes large, material segregation, separation of mixed materials, and moisture content may occur. There are also problems in material molding, such as a decrease in .

In order to solve these problems,
In No. 8410, a required number of molding machines are arranged in parallel, a common guide rail and a transfer member that moves along the guide rail are installed above the hoppers of the molding machines, and a predetermined number of molding machines are placed on the transfer member. In addition to installing material storage tanks,
A material supply method for a molding machine is proposed, in which a carrier bucket is attached to the transfer member, and the material is supplied by reciprocating the carrier bucket between the material storage tank and the hopper of each molding machine. has been done.

However, in the supply method according to this proposal, since the material to be supplied to each molding machine is provided in a predetermined number of material storage tanks on a transfer member provided above the molding machine, cleaning of the material storage tanks is required. However, it is difficult to supply the material to the material storage tank using means such as pneumatic transport, and simply installing a pipe hose using pneumatic transport in the space above rather than below is sufficient to solve the problem. The current situation is that this has not been achieved.

[Purpose of the invention]

The present invention has been proposed to solve the above-mentioned problems. In particular, in the space from the material supply station of molding material to each molding machine, there is no problem inherent to the above-mentioned pneumatic transportation, and moreover, The movable carrier is
It is an object of the present invention to provide a method for supplying material to a molding machine that can perform multi-purpose functions, allowing other work to be done during idle time other than material supply to the molding machine, and an apparatus used for carrying out the method.

[Disclosure of the invention]

The present invention proposed to achieve the above object stores the material metered and supplied from the material supply station in a closed container, and then moves the container along a rail constructed above to a position above the molding machine. The container is lowered and placed on the material supply hopper of the molding machine to supply the material contained in the container to the molding machine.

Further, the present invention device proposed at the same time includes a material supply station, at least one molding machine, a rail extending from the supply station above each molding machine, and a rail attached to the rail. It is characterized by being constructed by combining a carrier that moves reciprocally and moves up and down, and a closed-structure transfer container that is held by the carrier and moves along the rail.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of the apparatus of the present invention.

A is a material supply station, and a plurality of materials determined according to the molded product to be manufactured are mixed in advance at a mixing station (not shown) and sent to a hopper dryer At, where appropriate dehumidification is performed. Thereafter, it is automatically weighed and stored in the transport container E.

The automatic metering mechanism uses a rotary feeder A3 in the example, and the amount of material supplied for each molding iB installed in the system is controlled in advance by a control device installed in the central control panel E. The program is set. This program control is performed by setting a timer for one hour to drive the rotation of the valve of the row feeder A3.

The transport container F is of a closed type, as will be described in detail later.
It is formed in a sealed structure with a lower lid, and when placed in a predetermined position (indicated by (A)) on the container installation stand A5 of material supply station A, the upper lid is pushed down by the upper lid opening/closing device H, and a predetermined amount is material is stored in the transfer container E (see Fig. 4). When a predetermined amount of material is stored in the container E, the carriage A6 of the installation stand A5 moves and lifts the container F to the position ((ro). ) as shown in ). Here,! 5! The carriage A6 of the device A5 is configured to move back and forth by driving a motor and rotating a ball screw.

A plurality of forming machines are provided for one material supply station A, and each forming machine B...
It is possible to manufacture different types of molded products. The hopper Bl provided in each molding machine B... has an opening/closing lid B.
2 is provided, and the container F, which has been moved along the rail C by the carrier D from the material supply station A to a position above each molding machine B..., reaches a predetermined position in the hopper Bl of the molding JaB. When it descends, the opening/closing mechanism iB2 of hopper B1 is opened to receive the container F, and the downstream opening/closing device G is driven to push up the lower lid of the container F and transfer the material stored in the container to the hopper B1. (See Figure 5). Note that CI is a column supporting the rail C, C2 is a trolley duct provided to supply power to the carrier D, and A2 is a dehumidifier.

Next, the method of the present invention will be explained with reference to FIG.

When the container F is placed in the position shown in (A) at the material supply station A, the arm 213 of the top lid opening/closing device G
is driven to push down the top lid of the container F by the push-down member and open the sealing lid. At this time, the rotary valve rotates, and the material stored in the hopper dryer At through the supply pipe A4 is stored in the container F by its own weight. The lowered position of the arm 213 of the upper lid opening/closing device H is detected by position detection sensors Ll and L2 provided on the rod 214a of the air cylinder 214 that drives the arm 213 (detects the upper and lower limit positions of the rod), and The position of the carriage A6 on the mounting table 5 is detected by the sensor L3.

After the required amount of material is supplied into the container F, the rotation of the rotary valve A3 is stopped, and the carriage 86 of the mounting table A5 moves to the position shown in (b). At this position, there is a sensor L4 that confirms the presence of the container F, and a sensor L5 that detects the lowered position of the gripping arm 2 of the carrier D.
L6 is provided, and when the carrier lifting hand 8 extends and the gripping arm 2 descends to the position L5,
Decrease the descending speed and stop descending at position L6.

When the gripping arm 2 of the carrier D comes to this stop position, the container F is gripped as will be described later.

In this way, when the container F is gripped by the handle arm 2 of the carrier D, the elevating hand 8 of the carrier D is retracted and the carrier D rises while gripping the container F.

On the other hand, the carriage 10 of the carrier D has a gripping arm 2.
Upper and lower limit sensors L7 and L8 are provided to detect the ascending and descending positions of the gripping arm 2, and when the gripping arm 2 reaches the position of the sensor L8, the ascending speed is decelerated and the ascending is stopped at the position of L7.

When the gripping arm 2 stops at this position, the carriage 10
moves to above the position where molding aB is placed to receive material supply.

A position detection sensor Ln is placed at a location corresponding to the position where the formation fiB of the rail C is placed, and a position detection sensor Ln-1 is placed slightly in front of the position detection sensor Ln-1 in each molding 4! When the carriage 10 of the carrier D comes in front of the upper position of each molding mB, the position detection sensor Ln-1 detects this and the carriage 10 is decelerated, Ln-1 The carriage 10 can be stopped at the position.

The deceleration and stop position of the carriage IO is defined based on the control signal from the control panel E, and the carriage l of the carrier D
When O arrives at that location, the carrier D extends the lifting hand 8 and lowers the gripping arm 2. In this way,
When the carrier D hanging and holding the container F descends into the hopper B1 of the target molding machine B, the upper and lower limit detection sensors L9. L! O detects the position.

That is, when the detection sensor L9 detects the container F suspended on the carrier D, the lifting speed of the carrier D is reduced, and at the same time, the upper 11 of the hopper 81 of the molding machine B
7 is opened and the container F is placed in the upper opening of the hopper 81.
Place 2. The upper opening of the hopper Bl is provided with a push-up member for pushing up the lower lid of the container F, so when the container F is placed on the upper opening of the hopper 81, the lower lid is pushed up and held. The material stored in F is discharged into hopper B1 due to its own weight.

After the carrier D places the container F on the upper part of the molding machine hopper Bl, the carrier D further extends the lifting hand 8 and releases the grip on the container F. In this way, the carrier D, which has released its grip on the container F, retracts the elevating hand 8 that had been extended and ascends, thereby performing the necessary work.

That is, sprue discharged from other molding iBs.

It collects scraps from molded products such as runners, returns to supply station A, and transfers container F newly filled with material to another molding machine B.

Thus, while performing such necessary work, the material contained in the container F is completely discharged into the hopper Bl (this state is the same as when the container is placed on the hopper of the molding machine at 8
31i1), the carrier D becomes empty without holding the container F, and descends onto the hopper Bl of the forming JaB in the same manner as described above, Collect empty containers.

According to the method of the present invention, the efficiency of the system is extremely good because the free time can be used for other work, and it is possible to add traversers, turntables, etc. to the rail C! By adding position A, the work space can be used effectively and multi-purpose work with a wide range of work can be realized.

FIG. 6 shows a plan view of the upper lid portion of the ompper 81, showing the upper lid 217, 217 in a closed state.

Figure 7 shows the basic structure of the carrier D. Openings 1a and la are formed on the left and right sides of the base l, and one end is made to protrude from each of the openings 1a and la. 0 gripping arm 2.2, in which the gripping arm 2.2 is arranged.
Each of 2 is formed by overlapping two arm flat plates formed in the same shape with three mounting shaft members 2c, 2d, and 2e, and has a hook portion 2a and a small claw 3 at the tip. are doing. The small claw 3 is pivoted at a proper position on the arm 2 above the hook portion 2a, and is mounted between the shaft member 3b provided between the bifurcated claws and the above-mentioned mounting shaft member 2C of the arm 2. is gripped by the passed spring 30, that is, the hook portion 2a
It has a structure that constantly applies an elastic force in the direction. In addition,
3C is a stopper that regulates the closing angle of the small claw 3.

Each of the gripping arms 2 having such a structure is pivoted 2b to a mounting part 1b provided below the base 1, and is mounted on the shaft 2e of the acom 2 and the mounting plate IC at the center lower part of the base 1. is always biased with an elastic force in the closing direction by the passed spring 20.

The upper part of each gripping arm 2 protrudes from an opening 1a provided in the substrate 1, and a stopper piece 1d is provided on the outer edge of the opening 1a to regulate the closing angle when the arm 2 opens. There is.

Further, a pair of parallel levers 4a are arranged above the base l so as to be orthogonal to the upper end of each arm 2, and the parallel levers 4a are pivoted on the inside of the opening 1a with a support piece 4c. A spring 40 is provided at the end located outside the opening 1a.
is provided to apply an elastic force in a pulling direction toward the base l. A recess 4b having a sufficient width is formed in a portion of the parallel lever 4a corresponding to the upper end of the gripping arm 2. The provided mounting shaft 2d is engaged in sliding contact.

A parallel lever 4a and a spring 40 provided corresponding to the gripping arm 2 constitute an auxiliary measure 4, which applies braking force to the closing action of the spring 20 when the gripping arm 2 is opened and closed. This makes opening and closing operations smooth.

The base l has the above-described structure, and a pantograph-shaped lifting hand 8.8 is attached to both side pieces 5a, 5a of the housing 5 provided on the base l. A wire rope 7 is provided on the top plate of the housing 5 via a movable pulley 6.

The wire rope 7 is wound or unwound by a carriage 10 attached to a rail C (see Fig. 1) so as to be reciprocally movable, and the pantograph-shaped lifting hand 8.8 is extended and contracted to lift the base 1. let

8 and 9 show the structure of the carriage 10 of the carrier D. The carriage 10 has a pantograph-shaped elevating hand 8.8 disposed below a rectangular housing 101.
is provided to suspend the base 1.

102 is a geared motor, and its output shaft is provided with two sprockets 103 and 110.

The sprocket 103 is connected to the TLK via the chain 108.
The rotational force is transmitted to the N clutch 105 to rotate the driving wheel 106 mounted on the rail C to move the carriage 10, and the sprocket 110 rotates the wire take-up reel 114 via the chain 109 to move the base l. is raised and lowered. Further, 111 is a clutch that controls transmission of the rotational force of the motor 102 to the reel 114. When the electromagnetic clutch 105 is in the disengaged state, the rotational force of the motor 102 is not transmitted to the driving wheels 106.
The wire 7 is wound up or rewound by the forward and reverse rotation of the motor 102, and the base 1 is moved up and down. However, when the clutch 111 is in the disengaged state, the rotational operation of the wire take-up reel 114 is stopped. Carriage lO tracks C
When the rotation of the gear 102 is stopped, the above-mentioned lifting and lowering movements and reciprocating movements are stopped.

Note that 107 is a wheel, 104 is an electromagnetic brake that stops the rotation of the rotating shaft, and 112 is a wire guide roller. The carrier D grips the auxiliary plate 211b of the container F between the hook portion 2a and the small claw 3 of the gripping arm 2 by the operation described below, and lifts and lowers the lifting hand 8.8.
The carriage 10 can be moved up and down along the rail C.
can be moved and transported.

Next, the operation of carrier D will be explained.

The 10th episode shows the state (referred to as the reset state) in which the contracted elevating hand (not shown) is extended, the base l is lowered, and the container F is gripped. A pair of gripping arms 2.2 provided on the gripping arms 2.2 are positioned approximately parallel to each other under the tension of a spring 20.20.
is positioned closest to the hook portion 2a due to the tensile force of the spring 30 and the restricting force of the stopper 30.

Further, the parallel lever 4a of the auxiliary mechanism 4 also has a spring 40.
Since the arm 2 is positioned parallel to the base 1 due to the tensile force of the arm 2, almost no force is applied to the arm 2 in this state.

When the wire row 17 is unwound and the base 1 is further lowered in such a reset state, the tapered part 21'a formed at the tip of the hook part 2a of the arm 2 is connected to the tapered part of the auxiliary plate 210b of the container F. Upon contact, the arm 2 is gradually pushed apart against the elastic force of the spring 20, and as the arm 2 opens, the shaft 2d provided at the upper end of the arm 2, which is engaged in the space 4b with the parallel lever 4a, is opened. As it moves while sliding inward, the parallel lever 4a lifts the free end by the tension of the spring 4° (at this time, the small claw 3 also comes into contact with the tapered part of the auxiliary plate 210b of the container F, and the elasticity of the spring 30 (opens upward against the force). When the auxiliary plate 211b of the container F fits into the space between the hook 2a and the small claw 3 of the arm 2, the open arm 2
is closed by the tensile force of the spring 20. In this state, if the rotation of the motor 102 in the carriage 10 is stopped and the lifting and lowering of the base l is stopped, the arm 2゜2 will move between the small claw 3 and the hook portion 2a as shown in FIG. This means that the auxiliary plate 210b of the container F can be firmly gripped. When releasing the gripped container F, the motor 102
The wire row 1 wound on the reel 114 by rotating
7 and lower the base 1, and as the base 1 further descends, the small claw 3 opens upward against the elastic force of the spring 30, and the arm 2.2 also moves further. It is opened to the state shown in FIG. 12, and the grip on the container F is released. After releasing the grip on the container F in this way, the wire rope 7 is attached to the wire rope 1 in the carriage 10.
14 and further raises the base 1, the contact with the container F is lost, so the arms 2, 2 try to close instantly due to the restoring force of the springs 20 and 20, but the arms 2 and 2 open. As a result, the free end of the parallel lever 4a of the auxiliary mechanism 4 is lifted by the tensile force of the spring 40, and the arm 2.2 is loaded in the closing direction via the engagement recesses 4b, 4b of the parallel levers 4a, 4a. Since a counterforce acts, the arm 2.2 receives a braking force that is large at first and gradually decreases from the beginning of closing to the reset state, and the closing operation is performed slowly. In addition, the auxiliary mechanism 4
When the arm 2.degree. 2 is opened, a force in the opening direction is applied from the upper end of the gripping arm, so that the opening action is facilitated.

Note that after releasing the grip on container F, arm 2
It is necessary to lift the small claws 3.3 of , 2 and the hooks 'la, 'la to the position of the auxiliary plate 210b inside the container F. Therefore, in the reset state, the small claws 3 of arms 2, 2
, 3 and the hook portions 2a, 2a is called the container F.
Needless to say, it is necessary to set the thickness to be smaller than the thickness of the auxiliary plate 210b.

FIG. 13 shows the other side of the carrier D, in which the shafts 2d, 2d provided at one end of the arm 2.2 are attached to the parallel levers 4a, 4a of the auxiliary mechanism 4 when the grip of the arm 2.2 is released. The opening angle of the arm is determined by fitting the shafts 2d, 2d of the arms 2, 2 into the recesses 4b, 4b. . At the time of release, the arm 2.2 is moved by the parallel lever ~4a, 4a
Since the opening angle is fixed by fitting into the recesses 4b, 4b, it is necessary to release the engagement between the arm 2.2 and the parallel levers 4a, 4a when starting the gripping operation again.
For this reason, the axis 2d of arm 2.2.

2d is locked in the recesses 4b, 4b of the parallel levers 4a, 4a, and then the operation parts 12a, 12a of the reset member 12 are inserted into the protrusions (not shown) provided on the carriage 10 side.
The structure is such that the lyceter throat member 12 is brought into contact with the levers 12, and the parallel levers 4a, 4a raised at the free ends are pushed down to release the lock and return to the original state. Further, FIG. 14 shows an example in which the elevating hands 8', 8' provided on the carriage 10 have a structure in which a number of cylinders are concentrically and telescopically connected.
The descending hands 8', 8' automatically expand and contract as the base moves up and down.

(Effects of the Invention) As can be understood from the above explanation, the method and apparatus of the present invention have the following advantages over conventional pneumatic transportation methods.

l) Since the material for the molding machine is stored in a closed container and transferred in a stationary state, segregation or separation of the material does not occur during transfer, and the moisture content does not decrease. Therefore, it is extremely suitable for transporting mixed materials, etc.

2) Since there is no need for pipes like air transport, there is no need for troublesome vibrator wiring, there is no need to scatter dust around the work site, and there is no need for a clean amplifier.

3) Since a driving source such as pneumatic transportation is not used, a quiet working environment can be obtained without the influence of noise.

4) Since the sealed container moves along the rails built in the space above, the space on the ground can be used effectively, the work area becomes tidy, and the work space can be reduced.

5) Carriers that reciprocate along rails can transport various objects in addition to container transport, so free time can be used effectively to perform many types of work in parallel, resulting in extremely high work efficiency.
