Description

[Detailed description of the invention] This invention relates to a conveyance supply device.

A conventional example of a conveyance supply device is shown in FIG. In this figure,
The pace member 1 has a pair of struts 2. (3) are placed upright at a predetermined distance from each other. A carry-in conveyor 4 is provided between the pillars 2 and 3, with one end facing the supply source and the other end, the supply end, inclined low. The carry-in conveyor 4 is constituted by a gravity roller conveyor that rotates rollers 4α by a component force due to the weight of the transported object to transport the transported object.

At the end of the pace member l, there are struts 5, (lower than the struts 2 and 3).
6) are each erected. A housing support stand 7 is provided between the base columns 5 and 6, and the housing support stand 7 is swingable around a pin 8 provided at the free end of the support columns 5.6. Like the carry-in conveyor 4, the case support stand 7 is equipped with a plurality of conveying rollers 7α and also has a stop 4'7b for stopping the conveyed object.

An air cylinder 9 is provided on the pace member 1 so as to be swingable by a pin 11 via an auxiliary stand 10 for height adjustment. The rod 9α of the air cylinder 9 is connected to the front end side of the housing support 7 by a pin 12 so as to be able to swing freely, and supports the housing support 7 together with the columns 5 and 6. When not in operation, the housing support stand 7 is used as the carry-in conveyor 4
The housing is located at a first predetermined position near the delivery end of the housing and is continuously conveyed from the carry-in conveyor 4 to the housing support stand 7.

In a parts supply device having such a configuration, a transport box 15 is used as a housing for supplying parts to a worker, and the transport box 15 has an opening and a grid-like interior as shown in FIG. 2, for example. It is partitioned so that electronic components such as resistors and capacitors are housed and held within the partitions. Further, the worker performs assembly work etc. in front of the casing and the support stand 7 (on the left side of the casing support stand 7 in the figure). (In this case, it goes without saying that the loading section may be an automatic parts supply device.)
When supplying parts to a worker, first, the transport box 15 storing and holding the parts is placed on the carry-in conveyor 4, and is transported from the supply source side in the transport direction of the carry-in conveyor 4 by the gravity of the transport box 15. When the transport box 15 is transported from the carry-in conveyor 4 to the case support stand 7, the transport box 15 is moved to the stock A? 7b and stops on the housing support stand 7. When the operator confirms that the transport box 15 has been supplied to the housing support stand 7 in this way, the operator operates the air cylinder 9 by operating a switch or the like. When the air cylinder 9 is operated, the rod 9α is projected from inside the air cylinder 9, and the housing support 7 is moved together with the transport box 15 to the bin 8 in conjunction with the rod 9α.
The rod 9α rotates upward by an amount corresponding to the stroke of the rod 9α. At this time, the case support stand 7 is inclined at a predetermined angle as shown by the broken line A in FIG. Components can be easily taken out from 15 or moved to a predetermined location.

Next, when all the parts in the transport box 15 have been discharged, the operator removes the transport box 15 from the housing support base 7. Then, by operating a switch or the like again, the rod 9α is stored in the air cylinder 9, and the case support 7 is positioned at the first predetermined position near the A"Ak end of the carry-in conveyor 4, and the next transport box is carried in. It is supplied from the conveyor 4 to the case support stand 7.

However, in such a conveyance/supply device, once the parts in the transport box on the case support stand 7 are ejected and run out, a new transport box will be created unless the operator removes the transport box from the case support stand. Since the casing is not carried into the casing support table from the carrying conveyor, there is a problem that it causes a decrease in the work efficiency of the worker and is not suitable for automation.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a conveying and feeding device that realizes an automatic circulation transfer system and improves work efficiency.

The conveyance supply device according to the present invention includes a discharge conveyor provided above or below the carry-in conveyor for discharging the casing from a third predetermined position, and the casing is moved to the first position by the carry-in conveyor.
When the casing is carried into the predetermined position, the casing support is positioned at a first predetermined position, and when the casing is carried into the casing support, the casing support is tilted to be positioned at a second predetermined position, and the casing is then placed at a second predetermined position. The present invention is characterized in that an empty housing can be automatically discharged by a discharge conveyor by raising or lowering the body support base from a second predetermined position to a third predetermined position.

Embodiments of the present invention will be described below with reference to FIGS. 3 to 5.

In the conveying and supplying apparatus according to the present invention shown in FIG. 3, two pillars 22 and (23) are erected on the pace member 21, respectively. An inlet conveyor 24 is provided between the columns 22 and 23 with the supply end side inclined lower than the supply source side, and a discharge conveyor 25 is provided between the upper portions of the columns 22 and 23, which is different from the inlet conveyor 24. They are tilted in opposite directions. Loading conveyor 24 and discharge conveyor 2
5 is a conveyor similar to the carry-in conveyor 4 shown in FIG. Auxiliary stands 26 and 27 (27
(not shown) are provided respectively, and auxiliary stands 26, 2
Longitudinal members 29 and 30 (30 is not shown) are respectively provided on the conveyor 7 so as to be swingable and parallel to the carry-in conveyor 24 by means of pin paths. A housing support stand 31 is provided at the tips of the longitudinal members 29 and 30 so as to be swingable by a bin 32.
The case support stand 31 is constructed similarly to the case support stand 7 shown in FIG. The pace member 21 is also provided with two air cylinders 3j and 34. The air cylinder 33 is located closer to the pillar 22°23 than the air cylinder 34, and
The air cylinder 34 is also made swingable by a bottle 38 via an auxiliary stand 37. Rod 3 of air cylinder 33
3α is swingably connected to the front end side of the housing support 31 by a pin 39, and the rod 34α of the air cylinder 34 is swingably connected to the intermediate portion of the longitudinal members 29 and 30 by a pin 40. When the air cylinders 33 and 34 are inactive, the rods: Th and 34α are the air cylinders 33 and 3.
4, and at this time, the loading conveyor 24-4
A case support stand 31 is located near the end of the cheek and eyelid, so that objects to be transported are continuously carried into the case support stand 31 from the carry-in conveyor 24.

Note that a control circuit (not shown) is provided to control the air in the air cylinders 33 and 34, and the rod 33α or 34α is moved in accordance with the operation of a switch (not shown) connected to the control circuit. It is supposed to be done. That is, the first switch operation causes the rod 33α to protrude, the second switch operation causes the rod 34α to protrude, the third switch operation causes the rod 34α to return to its original position, and then the rod 33a also returns to its original position. This operation is repeated.

In the conveying and supplying apparatus according to the present invention having such a configuration, when parts are supplied to an operator using the transport box 15 shown in FIG. As in the conventional case, the housing is carried into the housing support stand 31 located at the first predetermined position. Then, when the operator operates the switch, the rod 33α moves to the air cylinder 33.
The housing support 31 protrudes from the housing support 31 and is rotated upwardly by the rod 334 together with the transport box 15 about the bin 32 by an amount corresponding to the stroke of the rod 9α. At this time, the case support stand 31 is tilted at a predetermined angle as shown in FIG. 4, and is located at a second predetermined position where the opening of the transport box 15 is substantially opposite to the operator. Up to this point, the operation is similar to that of the conventional example shown in FIG.

Next, when all the parts in the transport box 15 have been discharged, the operator operates a switch. Then, the rod 34 (Z) protrudes from the air cylinder 34, and the longitudinal members 29 and 30 rotate upward around the bottle by an amount corresponding to the stroke of the rod 34α, and in conjunction with the longitudinal members 29 and 30, the housing The support stand 31 also rises together with the transport box 15 while being supported by the air cylinder 33. Therefore, the case support stand 31 is positioned near the inlet end of the ejection conveyor 25 at an angle approximately equal to that of the ejection conveyor 25, as shown by the fifth tooth. !Position, housing support stand 3
1 and the discharge conveyor 25 form a continuous conveyance line, the transport box 15 is separated from the housing support base 3 and is conveyed by the discharge conveyor 25 in the discharge conveyance direction.

As described above, according to the conveyance and supply device according to the present invention, the discharge conveyor is provided above the carry-in conveyor, and the case support table is raised to the third predetermined position near the discharge conveyor, so that the case is supplied to the discharge conveyor. Since the container is configured so that it can be removed after parts have been supplied, the empty case such as the transport box can be easily ejected, and there is no need for an operator to remove it as in the conventional case. Therefore, with a simple operation, the worker can carry in the casing holding the parts and eject the empty casing, allowing him to concentrate on his original work, thereby improving his work efficiency.

In addition, in the conveying and supplying device of the present invention, the casing support base is not limited to being driven by switch operation as in the above embodiment, but a sensor for detecting the position of the casing or an electric switch is provided to drive the casing support base according to the sensor output. The housing support base may be automatically driven. Also, there is a stock I at the delivery end of the carry-in conveyor? It is also a good idea to set up the casing support table so that the casing support is activated when the casing support is driven, and not when it is not driven so that the next casing is waited for.
