Description

[Detailed description of the invention] This invention relates to the improvement of a conveyance device for transporting objects to the next process, in which the objects are locked to bars provided at the top and bottom, and the lower bars are moved up and down. The object of the present invention is to provide a simple conveying device that can move the conveyed objects forward and pack the conveyed objects first without providing a conveying pitch on the bar. .

In production factories, workpieces such as workpieces processed by press working, machining, etc. are transported by conveying devices such as roller conveyors, chain conveyors, belt conveyors, etc. according to various purposes such as processing, assembly, and transportation. be done.

Conveyance using these devices requires attachments to transport conveyor hangers and parts boxes.
Further, there was a problem in that it was not possible to pack the items at the front unless the items to be transported were collected.

In other words, in the case of conveyance using a roller conveyor, it is necessary to tilt the conveyance table for automatic conveyance, and it is also possible to convey small items and plates that are difficult to convey by themselves, and is suitable for items that require attachments for parts boxes. In order to transport the parts box, it is necessary to provide a hydraulic device to move the transport platform up and down at the front end.

In addition, for conveyance using a chain conveyor, etc., the conveyor hanger is fixed, so the hanger pitch cannot be changed, the conveyed objects cannot be arbitrarily packed first, and the equipment is large-scale. Therefore, the installation location is restricted,
It has disadvantages such as requiring a large driving force and high equipment costs.

This invention seeks to eliminate these drawbacks.

This invention will be explained as follows with regard to the embodiment shown in the drawings.

The conveying device of this invention includes a fixed bar 2, an operating bar 3, a front support IA that fixes the fixed bar 2 at the front and rear, and pivots the front end of the operating bar 3 so that it can rotate in the vertical direction; It is comprised of a rear strut 1B, a cylinder 5, etc., which periodically moves the rear end of the operating bar 3 up and down.

The front strut IA and the rear strut 1B are erected with an appropriate interval in the front-rear direction, and spacing members 16A and 16B are fixed between their upper and lower ends.

The fixing bar 2 is installed and fixed substantially horizontally at the upper end between the front column 1A and the rear column 1B.

The front end of the actuating bar 3 is pivotally connected to a bracket 4 attached near the lower end of the front strut 1A by a pin 8 so as to be rotatable in the vertical direction.

The rear end of the actuating bar 3 is pivoted vertically by a pin 18 at the tip of a rod 6 of a cylinder 5, which is attached to the rear column 1B via a bracket 17 so as to be swingable in the front-rear direction. It is worn.

Reference numeral 7 denotes a stopper for a transported object provided near the front end of the actuating bar 3.

The distance between the fixed bar 2 and the lower limit position P of the operating bar 3 is such that an upper hook part 10 that can be hooked to the fixed bar 2 is provided above, and a lower hook part 10 that can be hooked to the actuated bar 3 is located below. The interval is narrower than the distance between the upper hooking section 10 and the lower hooking section 11 of the conveyed object 9 having the stopping section 11 .

Further, at the lower limit position P of the actuating bar 3, the fixed bar 2 and the actuating bar 3 are in a substantially parallel state.

Note that the fixing bar 2 does not necessarily need to be fixed horizontally, and may be inclined downwardly or upwardly within a range with a small inclination, and the range of inclination is within a range where the object 9 to be transported can be transported. good.

The cylinder 5 moves the rear end of the operating bar 3 up and down.
is provided with limit switches (not shown) at the upper and lower limits of the stroke of the cylinder 5, and the operating bar 3
Its rear end is moved up and down periodically.

Next, a method of transporting the object 9 will be explained.

First, the object 9 to be transported is placed at position a shown in FIG. 3, with the upper hooking part 10 attached to the fixed bar 2 of the conveying device, the lower hooking part 11 being attached to the operating bar 3, and the upper hooking part 10 being tilted forward. Therefore, the distance between the fixed bar 2 and the lower limit position P of the actuating bar 3 is set to such an extent that the transported object 9 can be latched in an inclined state.

When the rear end of the actuating bar 3 is raised by the cylinder 5 in this state, the conveyed object 9 tends to fall forward, and the weight of the conveyed object 9 is applied to the actuating bar 3 side, causing the conveyed object 9 to fall forward. The sliding resistance between the actuating bar 3 is greater than the sliding resistance between the conveyed object 9 and the fixed bar 2.

Therefore, the fixed bar 2 side of the conveyed object 9 slides forward and falls forward as shown in b.

Next, when the rear end of the actuating bar 3 is lowered by the cylinder 5, the conveyed object 9 tries to stand up and the conveyed object 9
Much of its own weight is on the fixed bar 2 side, and the sliding resistance between the transported object 9 and the fixed bar 2 is greater than the sliding resistance between the transported object 9 and the operating bar 3.

Therefore, the operating bar 3 side of the IJ9 to be transported slides forward, and the to be transported 9I9 stands up as shown in C.

Thereafter, by repeating the vertical movement of the actuating bar 3, the object 9 to be transported is sequentially moved forward as d, e, and f, and is transported.

Therefore, even if the inclination is small (approximately 10 degrees) and the incline is downward or upward, the conveyance is possible as long as the object 9 to be conveyed can be latched in an inclined state as in the state a shown in FIG.

Note that an upper hooking portion 10 for hooking on the fixed bar 2 is provided above the conveyed object 9, and a lower hooking portion 11 for hooking on the operating bar 3 is provided below. Even when the bar 3 moves up and down, the conveyed object 9 does not come off the fixed bar 2 and the operating bar 3.

Furthermore, the number of fixed bars 2 and operating bars 3 is not limited to one each, and a plurality of them may be arranged in parallel.

FIG. 4 shows an embodiment in which an object to be transported 9 is provided with a pedestal 12 for the transported object, which is used for transporting small objects. 14, and the opening 14 has a hinge 1.
A lid 13 which can be opened and closed by means of 5 is provided.

Further, an upper latching part 10 for latching onto the fixed bar 2 is provided above the pedestal 12, and a lower latching part 11 for latching on the operating bar 3 is provided below.

As mentioned above, this invention allows the object to be transported to be moved into the transport device by hooking the upper end of the object to the fixed bar, hooking the lower end to the actuating bar, and moving the rear end of the actuating bar up and down. Since it is moved forward, 1. Limit switches are provided at the upper and lower limits of the cylinder to automatically move the operating bar up and down, eliminating the need for human power for transportation.

2. When the transported object advances to the previous transported object, it will no longer be able to slide on the fixed bar and will automatically stop, allowing for aphasia.

3. The structure is simpler and cheaper than conventional conveying devices.

4. The conveyance speed can be adjusted by changing the vertical stroke or vertical cycle of the operating bar (by adding a timer).

5. Even if the conveyance device is installed at an upward slope of about 10°, conveyance is possible.

6. It has the advantage that it can also serve as a simple storage for objects to be transported.
