DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for separating and aligning a large number of cylindrical or columnar works put into a storage container and supplying the required amount for the next process.

[0002]

2. Description of the Related Art For example, a tube-shaped container for containing creamy cosmetics or medicines such as toothpaste, or creamy foods such as toothpaste and the like, is provided with a cap member and a one-letter seal above and below a synthetic resin cylinder such as polypropylene. Part is provided. In order to supply the above-mentioned cylinder to this type of tubular container assembling machine, it is necessary to feed the necessary amount according to the assembling work capacity in an aligned state.

[0003] When a conventional vibratory feeder having a circular hopper is used to supply a relatively large and light work as described above, the diameter of the hopper becomes very large and a light object is moved unless the amplitude is increased. Can not do. For this reason, there is a problem that the noise is loud and a muffler must be provided.

Therefore, there is a component supply device disclosed in Japanese Patent Application Laid-Open No. H2-1110016 shown in FIG. 10 for a cylindrical or columnar work which is not suitable for the above-mentioned vibration type supply device.
This device accumulates a round bar or a cylindrical material S in the end portion of the chute 102 on the bottom plate of the hopper 101 in the same direction and accumulates the material S, and feed plates 111 to 119 including moving plates 111A to 119A and fixed plates 111B to 119B. Are arranged in parallel, and the movable plates 111A to 119A are moved upward by the actuator 103 all at once, so that the accumulated materials S are placed one by one on the lowermost movable plate 111A and the fixed plate 111B is fixed.
Put it on top. Next, the material S on the fixed plate 111B is moved to the next moving plate 1 by moving the moving plate downward at a stroke.
Fall over 12A. In this way, the materials S are successively replaced and sent to the next process.

[0005]

In the component supply apparatus disclosed in Japanese Patent Application Laid-Open No. H2-1110016, the material S must be accumulated in the direction of the end of the chute 102 in the same direction.
It takes a lot of labor. In addition, in the case of a material that is relatively easy to transport, such as a metal material, that rolls smoothly on the lowest moving plate while maintaining a stable stacked state, a stable supply amount can always be obtained. Workpieces that are light and easily move with slight interference, such as resin-made cylindrical or cylindrical workpieces, are likely to fall off during transportation, so the feeding amount on the moving plate is unstable, and the feeding amount in the next process There is a problem that it does not match the required amount.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to allow a work to be randomly loaded into a storage container without worrying about the direction. It is an object of the present invention to provide a work aligning and supplying apparatus capable of separating and aligning a work put into a storage container and reliably supplying a required amount of a next process.

[0007]

In order to achieve the above object, the work aligning and feeding apparatus according to the present invention requires a next step by aligning a large number of cylindrical or columnar works put into a storage container.

A partition plate, first drive means for raising the partition plate and lowering the partition plate in a stepwise manner, and projecting substantially perpendicularly from two long holes formed in the inclined plate in front and rear of the partition plate in parallel with each other. First and second movable plates that can be moved up and down, second and third driving devices that continuously move the first and second aligned plates up and down, respectively, and a terminal of the inclined plate. And the inner wall of the storage container A plurality of elevating plates and a plurality of fixed plates having an upper surface having substantially the same inclination angle as the inclined plate are alternately arranged in parallel such that the inner wall side of the storage container is higher, and the upper end surface of the fixed plate is An upper end surface which is fixed stepwise at an interval equal to the moving amount of the elevating plate and which is inclined by downward movement of the stepped elevating plate at an interval equal to the moving amount is inclined by the inclined plate and the fixed plate. Upon receiving the work in alignment with the upper end surface and moving the lift plate upward, the inclined upper end surface of the lift plate coincides with the inclined upper end surface of the fixed plate to reload the work and the inner wall of the storage container. A delivery member for carrying out of the storage container from the window provided on the inner wall to the outside of the storage container from the contacting lifting plate, fourth driving means for vertically moving the lifting plate of the delivery member, and the delivery member is carried out of the storage container through the window. Guided work to conveyor That the swinging shutter the workpiece provided on the chute plate damming in a row sent intermittently, a fifth driving means for driving in conjunction with launching member said rocking shutter, at delivery end side on the conveyor A sensor provided at a position capable of detecting the minimum holding amount of a workpiece waiting for transfer to the next process, and the actuators of the fourth driving means and the fifth driving means are input / output by a signal of the sensor. Control means for turning off.

[0008]

The work stored in the first storage room and the second storage room separated by the partition plate in the storage container is the first alignment plate and the second storage room.
Separation and alignment are performed by each vertical movement with the alignment plate. Then, when the number of storage works in the second storage chamber becomes equal to or less than the set minimum number by the sending-out member, the partition plate is automatically lowered one step at a time and works are sent from the first storage chamber to the second storage chamber. When the storage work in the first storage room and the second storage room becomes less than the minimum, the partition plate is raised to the uppermost stage, and then the worker is notified of a work replenishment request by a display lamp or a buzzer. When the operator inputs a predetermined amount of work, the operation automatically returns to the initial step.

On the other hand, the delivery member and the oscillating shutter
The interlocking is started by a sensor signal indicating that the number of workpieces waiting on the work conveyor has become a minimum or less.
The swing shutter pivots so that the pawls (bent portions) on the work conveyor side are opened, and transfers a row of works blocked by the bend portions onto the work conveyor via the chute plate, and then pivots in the opposite direction. To return to the position where the work is blocked.

[0010] In conjunction with the swing shutter, the plurality of step-like lift plates, which are located at the lower end position of the feeding member, are raised to the upper end positions, so that the work placed on each inclined upper end surface is stepped. The work is placed on the inclined upper end surface of the plurality of fixed plates, and the work placed on the highest lifting plate in contact with the inner wall of the storage container is sent out of the storage container through the window. This interlocking operation between the feeding member and the swing shutter is repeated while confirming until the sensor signal on the work conveyor disappears.

Next, in step S11, the worker manually loads the work W into the first storage room a. It is desirable that the work input amount at this time is such that a predetermined amount of the work W is transferred into the second storage chamber b beyond the partition plate 6 as shown in FIG. When the loading of the work W is completed, the sensor O
P1 or the signal of the sensor OP1 and the sensor OP2 automatically returns to the step S2 and returns to the step S2.
In steps S4 to S4, the alignment operation by the vertical movement of the first alignment plate 13 and the second alignment plate 14 is repeated.

Next, in step S12, it is confirmed by the work confirmation sensor OP3 whether or not the minimum work W is present on the work conveyor 40. If the result is NO, in step S13, FIG. 5 and FIG. Air is sent to the upper chamber of the air cylinder 35 shown in FIG.

18C returns to the standby position shown in FIG. 5 and FIG.
One cycle of the transfer of the work W and the transfer operation to the conveyor belt 44 is completed.

The delivery amount of the work W by the delivery member 17 is higher than the amount required for the next process. However, if the required amount of the work W is not delivered in the above-described one cycle operation, Since the NO state continues in step S12, the above-described operation of feeding the workpiece W in steps S13 and S14 is repeated. .

If the answer is YES in step S12, in step S15, the lifting plates 18A, 18B,
18C and the oscillating shutter 32 stand by while being stopped,
In step S16, for example, it is confirmed whether a machine stop signal from the next process is output. If NO, the process returns to step S2. If YES, the main switch is automatically turned off in step S17, and the process ends.

In addition to the above-described embodiment in which the stop of the first aligning plate 13 and the second aligning plate 14 at the descending end position is stopped by YES in step 8, the first aligning plate 13 is The case where the NO and the second alignment plate 14 are stopped at the respective lower end positions in separate steps of NO in Step 4 is also included in the present invention.

[0045]

Since the work aligning and feeding device of the present invention is constructed as described above, the following effects can be obtained.
Since the first storage chamber and the second storage chamber, which are separated by partitioning plates that descend step by step, are provided with alignment plates that can move up and down, respectively, to separate and align the workpieces, a relatively large number of workpieces are arranged. Can be introduced without considering the directionality, the labor for replenishing the work is reduced, and manpower can be saved. Further, since the work is sent out using a sending member in which a plurality of elevating plates and fixed plates are arranged in a stepwise manner, if the outer diameter difference of the work is about 20 mm, there is no need to replace parts. Available and highly versatile.

Further, since the feeding member and the oscillating shutter having a supply capacity greater than the required amount in the next process are controlled by the signal of the work confirmation sensor on the work conveyor, the supply amount is adjusted, so that it is difficult. It is possible to always supply and supply a required amount of a light-weight, easily-movable work that can be transported.

The upper end surface inclined by the downward movement of the step-shaped elevating plate coincides with the inclined upper end surfaces of the inclined plate and the fixed plate to receive a work, and the upward movement of the elevating plate causes the upward movement of the elevating plate. The upper end inclined surface coincides with the inclined upper end surface of the fixed plate to reload the work, and the unloading plate is brought out of the storage container through the window provided on the inner wall from the elevating plate in contact with the inner wall of the storage container. And a fourth member for vertically moving the elevating plate of the sending member.
A driving means, a swing shutter provided on a chute plate for guiding the work carried out of the storage container out of the window to the conveyor, and intermittently feeding the works in a row and intermittently feeding the work; and Fifth driven in conjunction with
A driving unit, a sensor provided at a position on the delivery end side of the conveyor that can detect a minimum holding amount of a workpiece waiting for transfer to a next process, and the fourth driving unit based on a signal of the sensor. And a control means for turning on and off each actuator of a fifth driving means.
