Abstract

PURPOSE:To simplify the structure for transfer by a constitution wherein a driving wheel driving chain conveyors provided in front and rear lines respectively is arranged between these conveyors and transfer jigs are provided radially on the driving wheel in a method for transferring a load between said conveyors. CONSTITUTION:When a driving wheel 5 is roated by a driving power member 7 through the intermediary of a chain 8, the respective chain conveyors 1 and 2 of front and rear lines pressed on the driving wheel 5 by a pair of counter wheels 15 respectively are operated in synchronization. On the occasion, load supporting pawls 14 of transfer jigs 10 provided on the driving wheel 5 advance in gearing with load supporters 3 of the conveyor 1, and guide rollers 13 run on a fixed rail 9. Therefore the whole of the jigs 10 are raised with the rise in a track of the rail 9. Thereby loads 4 on the load supporters 3 are received and supported sequentially by the load supporting pawls 14. The operation as described above is performed in an entirely reverse sequence on the rear line side, and thus the loads 4 on the pawls 14 are transferred onto load supporters 3 on the rear line.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applicable to a chain conveyor in which a load is loaded above the conveyor chain and conveyed, and a trolley conveyor in which the load is suspended and conveyed below the conveyor chain. This relates to an automatic transfer method for transferring cargo to the next line.

In general, when transferring between two conveyors in the front and rear lines, there are many methods in which the conveyors in the front and rear lines perform synchronized operation at the same speed and in the same phase, and the transfer mechanism is driven by a drive unit. The transfer mechanism is provided with a mechanism for unloading from the conveyor in the front line and a mechanism for loading onto the conveyor in the rear line, and is often equipped with an electrical position detection device.

For trolley conveyors, there is a transfer method using a double-acting trolley conveyor that does not require synchronized operation of the conveyors in the front and rear lines. Moreover, the structure is complicated.

The Ki-en provides a more stable and reliable transfer method using a simple mechanism. In the method of transferring the load to the other chain conveyor which also rotates endlessly and whose side chain part is arranged in parallel opposite to the unloading side chain part of the one chain conveyor, the unloading side chain part and the loading side chain part are arranged in parallel. A common drive wheel that meshes with the chain conveyors is provided to drive both chain conveyors, and transfer jigs are provided radially around the periphery of the drive coil, and one chain is connected to the unloading side chain. This automatic transfer method is characterized by receiving a load being conveyed on a conveyor and transferring the received load to a load-side chain portion of the other chain conveyor.

When carrying out the method of the present invention, if the distance between the drive chain height and the load height or suspended load height is approximately the same in the front and rear lines, one drive wheel provided on the vertical axis is used for the transfer. If the distance is different between the front and rear lines, the transfer is performed using two drive wheels installed above and below a common vertical drive shaft. By this method, the drive unit and the transfer mechanism unit are integrated, that is, the front and rear line conveyors are directly connected at the transfer mechanism unit position, and synchronized operation at the same speed and phase can be performed reliably and safely. Moreover, the mechanism is simple and economical, and it is also convenient in that the drive section and the transfer mechanism section can be performed in the same place during daily maintenance and inspection.

Next, an embodiment in which one driving wheel is used in an automatic transfer method for a chain conveyor in which a load is loaded and conveyed above a conveyor chain will be described with reference to FIGS. 1 and 2.

1 indicates the conveyor on the front line, and s indicates the conveyor on the back line. Reference numeral 3 designates a load support device fixed to the chain of a chain conveyor. In this embodiment, the load 4 to be conveyed is supported by using the center hole on the lower surface of the load 4, so the load support device 3 has a thin upper part and an acute angle at the tip, and a lower part. is a stepped rod shape that is thicker. Further, the load supporting devices 3 are attached at a constant rate, one for every two links of the chain. Does the drive boiler 5 rotate around the fixed shaft 6? The chain conveyor of the front line and the rear line is simultaneously driven by the meshing teeth of the drive wheel 5. Reference numerals 7 and 8 indicate a drive power section and a power transmission chain that are chain-connected to the drive wheel 5 to drive the drive boiler 5. Fixed rail 9
is an annular rail supported and fixed by another support (not shown) above the drive boiler 5, and serves as a guide for raising and lowering a transfer jig 1°, which will be described later. That is, on the front line side, the fixed rail 9 is set on an upward trajectory so as to rise as the transfer jig 1o advances in order to unload the load 4 from the line, and on the other hand, on the rear line side, the load 4 is delivered to the line. Therefore, the transfer jig 10 is set on a descending trajectory so that it descends sequentially. The transfer jig 1o can slide up and down with little play along the support 1111 fixed to the upper surface of the drive wheel 5, and has a structure 12, and a guide roller 13 at one end of the transfer jig 1o. It rides on the fixed rail 9, and a horseshoe-shaped load support claw 14 with an acute angle at the tip for supporting the load 4 is attached to the other end. Support rod 1
In this embodiment, 12 pairs of reeds 1 are provided in pairs, and when the chains of the conveyors in the front and rear lines are engaged with the drive boiler 5, the mounting position is the load supporting claw of the transfer jig 1o. 14 and the load support 3 are positioned at the same position and engage with each other.

The counter wheels 15 are arranged to press the respective conveyor chains in the front and rear lines so that they mesh with the drive wheels 5. The number of engagements between the chains and the drive wheels 5 changes depending on the position of the arrangement. Four supporting tools 3 and four transfer jigs 10 are engaged with each other. The number of engagements may be two or more.

The operation of the device constructed as above will be described below.

The power of the drive power unit 7 is transmitted to the drive wheel 5 by the power transmission chain 8, and the drive wheel 5 mechanically synchronizes the chain conveyor in the front line and the chain conveyor in the back line at the same speed and phase. It will be in operation state.

In this state, the state of unloading from the conveyor on the front line will be described in detail below.

As the drive wheel 5 rotates, the upper surface of the drive wheel 5 is
The load supporting mold 14 of the attached transfer jig 10 and the load supporting tool 3 of the conveyor on the front line completely mesh with each other and move in the same direction. At the same time, the idle roller 1 of the transfer jig 10
The guide roller 13 also rises as the fixed rail 9 moves up on the track of the three-way fixed rail 9, and therefore the entire transfer jig 10 also rises. That is, at the beginning of engagement between the transfer jig 1o and the load support 3, the load support mold 14 enters with a gap below the load 4 loaded on the load support 3. As the drive wheel 5 rotates, the guide roller 13 running on the fixed rail 9 forming the ascending track rises, and accordingly the load supporting mold 14 at the other end of the transfer jig 10 rises. The load 4 comes into contact with the load 4 loaded on the load support holder 3, and as the drive wheel 5 rotates, the load 4 is completely loaded onto the load support die 14 and unloaded from the load support 3.

In this way, the loads 4 are sequentially unloaded from the front line. On the rear line side, the exact opposite of the above is performed, and the loads 4 loaded on the transfer jig 10 from the front line are sequentially transferred to the load support 3 on the rear line. The state on the rear line side will be described in detail below.

As the drive wheel 5 rotates, the load support type 1 of the transfer jig 10
4 and the load support 3 of the conveyor on the rear line completely mesh with each other and move in the same direction. At the same time, the guide roller 13 of the transfer jig 10 runs on the track of the fixed rail 9, and as the fixed rail 9 descends on the track, the guide roller 13 also descends, and therefore the entire transfer jig 10 also descends. That is, the transfer jig lO
At the beginning of engagement between the load supporting tool 3 and the load supporting tool 3, the load supporting tool 3 enters with a gap below the load 4 loaded on the load supporting mold 14 of the transfer jig IO. As the drive wheel 5 rotates, the guide roller 13 running on the fixed rail 9 forming a descending track descends, and therefore the load 4 on the load support mold 14 of the transfer jig 10 descends. and comes into contact with the load support 3,
Furthermore, as the drive wheel 5 rotates, the load 4 descends, is completely loaded onto the load support 3 on the rear line, and is unloaded from the transfer jig 10.

In this way, the loads 4 on the front line are sequentially transferred onto the rear line via the transfer jig 10.

Next, an embodiment in which a single drive wheel is used in an automatic transfer method for a trolley conveyor for suspending and conveying a load below a conveyor chain will be described with reference to FIGS. 3 and 4.

Reference numeral 16 indicates a trolley conveyor on the front line, and reference numeral 17 indicates a trolley conveyor on the rear line. The load support 18 has holes in the upper position and the middle position. The perforation, ie, the central hole 21, is a perforation for hanging on a transfer jig 22, which will be described later. The lower position 12 of the load support 18 is the hook 2
3 is suspended from the hook 23, and a load 24 to be transported is suspended from the hook 23. The drive wheel 25Ifi can drive the front and rear line trolley conveyors simultaneously. The fixed rail 26 is an annular rail supported and fixed by another support (not shown) below the drive wheel 25, and serves as a guide for raising and lowering the transfer jig 22, which will be described later.

That is, on the front line side, the fixed rail 26 is set as an ascending track so that it rises as the transfer jig 22 advances in order to unload the load 24 from the line, and on the other hand, on the rear line side, the load 24 is delivered to the line. Therefore, the transfer jig 22 is set on a descending trajectory so that it descends sequentially. Can the transfer jig 22 be slid up and down with little play along the support rod 27 fixed to the lower surface of the drive wheel 25? The transfer jig 22 has a guide roller 29 at one end that rides on the fixed rail 26, and the other end supports the load support 18 on which the load 24 is suspended. A load supporting mold 30 is attached to support the load. The support rods 27 are a pair of two, and their mounting positions are set at the transfer jig 22 when the chains of the trolley conveyors on the front and rear lines are engaged with the drive wheel 25.
The load supporting weight 30 is inserted into the middle hole 21 of the load supporting tool 18. Although not shown, a counter wheel is arranged at a position corresponding to that shown in FIG.

The operation of the device constructed as above will be described below.

The power of a drive power section (not shown) is transmitted to the drive wheel 25 by a power transmission chain, and the drive wheel 25
Mechanically, the trolley conveyor in the front line and the trolley conveyor in the rear line are mechanically synchronized with the same speed and phase.

As the drive wheel 25 rotates, the load support type 30 of the transfer jig 22 attached to the lower surface of the drive wheel 25 and the hook 20 of the trolley conveyor on the front line suspend the load 2.
4 is completely inserted into the middle hole 21 of the load support 18 which is suspending the load, and moves in the same direction. At the same time, the guide roller 29 of the transfer jig 22 runs on the track of the fixed rail A/26, and as the fixed rail 26 moves up the track, the guide roller 29 also rises, and therefore the entire transfer jig 22 also rises. That is, when the transfer jig 22 and the load support 18 are first inserted into each other, the load support mold 30 is inserted into the upper edge of the central hole 21 of the load support 18 with a gap. As the drive wheel 25 rotates, the idle roller 29 moves up while traveling on the fixed rail 26 forming a rising track, and therefore the transfer jig 2
The load support mold 30 at the other end of the load support mold 30 rises and comes into contact with the upper edge of the middle hole 21 of the load support tool 18, and as the drive wheel 25 rotates, the load support tool 18 is completely attached to the load support mold 30. The supporting part is detached from the hook 20 of the trolley conveyor. That is, load 2
4 is suspended from the load support 18, unloaded from the trolley conveyor on the front line, and transferred to the transfer jig 22.

In this way, the loads 24 are sequentially unloaded from the front line.

On the back line side, everything is done in reverse to the above, and the load 2 suspended from the front line to the transfer jig 22 together with the load support 18 is
4, the state on the rear line side where the load is sequentially transferred to the hook 20 of the trolley conveyor on the rear line together with the load support 18 will be described in detail below.

As the drive wheel 25 rotates, the upper hole 19 of the load support 18 suspended from the load support mold 30 of the transfer jig 22 and the hook 20 of the trolley conveyor are completely inserted and moved in the same direction. proceed. At the same time, the guide roller 2 of the transfer jig 22
9 runs on the track of the fixed rail 26, and as the fixed rail 26 descends on the track, the guide roller 29 also descends, and therefore the entire transfer jig 22 also descends. That is, when the upper hole 19 of the load support 18 suspended from the transfer jig 22 and the hook 20 of the trolley conveyor are initially inserted, there is a gap between the upper hole 19 of the load support 18 and the trolley conveyor. The hook 20 of the conveyor is inserted. As the drive wheel 25 rotates,
The guide rollers 29 running on the fixed rails 26 forming the descending track descend, and the load support 18 supported by the load support mold 30 of the transfer jig 22 descends, and the hook of the trolley conveyor descends. 20, and as the drive wheel 250 rotates, the load support 18 descends and is completely suspended from the hook 20 of the trolley conveyor on the rear line. That is, the load 24 is transferred while being suspended from the load support 18.

The method of the embodiment shown in FIGS. 1 to 4 above is an embodiment in which the distance between the height of the drive chain and the height of the load or the suspended load is approximately the same in the front and rear lines. Approximately the same here.
This refers to a difference in the spacing between the front and back lines of about 30 cages or less, but in the case of a difference in the spacing of this degree, the slope of the ascending track or descending track of the fixed rail in the above embodiment should be selected appropriately. It can be carried out by

However, depending on the work content of the front and rear lines, the distance between the drive chain height and the load height or suspended load height may vary.
For example, there are cases where a difference of 100 meters or more is required between the front and rear lines. In such a case, the transfer can be carried out by using two coaxial drive wheels.

FIG. 5 shows an embodiment using two coaxial drive wheels. The nuclear diagram shows that for a chain conveyor that loads and transports a load above the conveyor chain, the loading height above the floor is the same for the front and rear lines, but the height of the drive chain from the floor is This shows a case where the line is high and the back line is low.

31 indicates a conveyor on the front line, and 32 indicates a conveyor on the rear line. The drive wheels are arranged above and below a death part 34 that rotates around a fixed shaft 33, and constitute a lower drive wheel 35 and a lower drive wheel 36, respectively.The lower drive wheel 35 controls the front line, and the lower drive wheel 36 controls the front line. Drives the chain conveyor on the rear line at the same time. That is, the lower drive wheel 3
5 and the position of the lower drive wheel 36 on the death part 34 directly becomes the difference in the height of the drive chain between the front and rear lines.

The loading height is approximately the same on the front and rear lines, so the distance between the drive chain height and the loading height is small on the front line and large on the rear line. Accordingly, the length of the rod-shaped support part of the load supporter 37 is shortened in the front line and lengthened in the rear line. The transfer jig 38 and the support rod 39 are attached to the lower drive wheel 35, and the fixed rail 40 is supported and fixed above the lower drive wheel 35 by a support (not shown).

The other detailed configurations of the transfer jig 38, support rod 39, and fixed rail 40 are the same as those in FIGS. 1 and 2 of the previous embodiment.

By driving the device having the above configuration, it is possible to reliably and safely transfer the load on the chain conveyor in the front line to the chain conveyor in the rear line.

In addition to the above, there are three other embodiments when the distance between the drive chain height and the load height or suspended load height needs to be different between the front and rear lines. That is, the first embodiment is a chain conveyor that loads a load, and the distance between the height of the drive chain and the height of the load is larger in the front line than in the rear line. The rear line is driven by the foil, and the transfer jig, support rod, and fixed rail are installed on or above the lower drive foil. Next, as another 29 embodiments, there are two cases in which the distance between the drive chain height and the suspended load height is smaller on the front line and larger than the rear line in a trolley conveyor that suspends loads.

In the former, the lower drive wheel drives the front line, and the lower drive wheel drives the rear line, and in the latter, the lower drive wheel drives the front line, and the lower drive wheel drives the rear line.
The support rod and fixed rail are installed on or below the lower drive wheel.

As described above, the present invention enables reliable and safe transfer by performing synchronized operation of the conveyors 9 in the front and rear lines and transfer at the drive wheel position, and also eliminates the need for a complicated control mechanism as in the past. The effect is remarkable.
