Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a stack feeder used to separate a large number of stacked blanks one by one and feed them to a press machine, etc. In particular, the present invention relates to improvements in the loading section for blank materials.

[Background technology and its problems]

Conventionally, a large number of blank materials punched by a blanking press are stacked as one stack, and the large number of stacks are stacked on a pallet. Generally, each stack on this pallet is wrapped around a wire and lifted by a crane using a so-called slinging operation, and in this state is supplied to a stack feeder.

However, when supplying the board by lifting it by slinging, it is necessary to supply one stack at a time, which is not only inefficient, but also has the disadvantage that the board may be damaged by the slinging.

Therefore, it has been desired to develop a disk stack feeder that can efficiently receive blanks without damaging the blanks.

[Purpose of invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a stack feeder which does not damage blanks and has good working efficiency, which can feed a plurality of stacks of blanks from the blanking press side.

[Means and actions for solving problems]

In this invention, a fixed roller chute is provided on the main body frame of the stack feeder, and a lift plate having a large number of rollers that is lifted by a lift cylinder and can be arranged at the same height as the fixed roller chute is provided. A floating device having a blank separation mechanism for separating blanks on a plate can be reciprocated between the installation position of a data stack cylinder that sucks and supports the blank at the uppermost position and a position away from this installation position.2 A lifting table is provided on one side of the main body frame, and
A movable roller chute that is lifted to the same height as the fixed roller chute by the lifting table is removably provided, and a magazine that can be hung with blanks loaded on the movable roller chute is provided. Two movable carts that can be placed freely and pass through the lifting table are provided so as to be able to reciprocate between the installation position of the lifting table and a position away from this installation position, and furthermore, two movable carts are installed on the movable roller chute of the magazine. A stack feeder is constructed by providing a blank material moving means that enables the stack of blank materials to be transferred onto the rollers of the lift plate via a fixed roller chute.

The operation of the disk feeder having such a structure is as follows.

That is, one or more stacks of blanks are stacked on the movable roller chute of the magazine, the whole magazine is moved from the blanking press position to the stack feeder position, and placed on one of two movable carts. The movable cart on which the magazine is mounted is moved to the lifting table side. Only the movable roller chute is lifted from the magazine on the movable cart to the position of the fixed roller chute by a lifting table, and in this state, one stack of blanks on the movable roller chute is moved onto the lift plate by the blank material moving means via the fixed roller chute. onto the rollers. In this state, the lift plate is raised by a lift cylinder, and one of the floating devices, which is preset to the shape of the transferred blank, separates each blank and sequentially de-stars the uppermost blank. A pick cylinder is used to transport out one sheet at a time.

As a result, in the present invention, instead of carrying in blanks by slinging, one or several stacks are loaded on the movable roller chute of the magazine, and the whole magazine is moved to the main body frame side of the day stack feeder. In addition to preventing damage, it is possible to transfer multiple stacks of blanks onto the movable roller chute, and by using two movable carts to place the magazines, it is possible to improve the efficiency of magazine loading. By having two floating devices, we can immediately respond to differences in the shape of blank materials, improving work efficiency.
This aims to achieve the above objective.

is fixed. The other end of the chain 41 is engaged with these sprockets 67, and the other end of the chain 41 is housed in a chain receiver 68 (see FIG. 2) provided in the main body frame 1. has been done.

Note that the chain 41, shafts 42A, 42B,
Hook bracket 43, roller 44, spindle 45,
The hook 46, the tension coil spring 47, the motor 61, the coupling 63, the connecting shaft 64, the clutch 65 and the sprocket 67 constitute a blank material moving means 69. Further, the motor 61, the coupling 63, the connecting shaft 64, and the sprocket 67 constitute driving means for the chain 41 as a push/pull connecting means.

Next, the operation of this embodiment will be explained.

A plurality of blank materials 12 punched by a blanking press (not shown) are stacked at a predetermined height on a movable roller chute 58 of a magazine 55 disposed near the blanking press. In this case, the stacks of blank materials 12 need only be spaced apart enough so that the hooks 46, which are attached to the chain 41 so as to be able to rise and fall, can stand between the stacks, and in particular, they need to be installed in a precise arrangement. There isn't.

In this way, a plurality of stacks of blank materials 12
The magazine 55 loaded with the magazine 55 is lifted by a crane or the like using the lifting hook 56.
It is placed on a moving cart 52. This magazine 55
The movable trolley 52 on which is placed is moved to a position facing the main body frame 1 and stopped, and in this state, the cylinder 36 is activated, and each movable roller chute 58 in the magazine 55 is lifted by the lifting table 38. The height position of each movable roller chute 58 is made to match the height position of the fixed roller chute 3 fixed to the main body frame 1, and the height position of the chain guide 40 of the lifting table 38 and the chain guide 4 of the main body frame 1 is made to match. are matched. At this time, the piston rod 11 of the lift cylinder 10 is located at the lowest position, and in this state, the height position of the lifting roller chute 6 of the lift plate 7 also matches the height position of the fixed roller chute 3.

In this state, when the clutch 65 is disengaged and the pair of motors 61 are driven in the chain feeding direction, the hook bracket 4, which was initially located on the chain guide 4 side of the main body frame 1, is moved.
3 will move toward the chain guide 40 side of the lifting table 38. As the hook bracket 43 moves toward the chain guide 40, the hook 46 protruding from the upper surface of the movable roller chute 58 comes into contact with the lower part of the blank material 12 placed on the movable roller chute 58. When it comes into contact with the hook 4
6 resists the tension coil spring 47 having a relatively weak spring force, falls down, goes under the blank material 12, passes under this blank material 12, is moved to the rear of the blank material 12, and is moved to the rear of the blank material 12. When passing under the material 12, the movable roller chute 5 is moved again by the action of the tension coil spring 47.
Projected above 8. This ups and downs of the hook 46 are detected by a switch 48, and the hook 46 is connected to one blank material 12 by one ups and downs of the hook 46.
It is detected that the motor 61 has passed below the stack, and the motor 61 is stopped in response to this detection signal. At this time, switch 4 corresponding to each hook 46
The detection signal of 8 is the motor 6 that drives the hook 46.
A signal is transmitted to the first power supply circuit, and the motor 61 that drives the chain 41 is stopped. Therefore, when the blank material 12 has an irregular shape that is not a rectangular parallelepiped as shown in FIG. 1, that is, a blank material 12 with one side inclined as shown in FIG. In other words, the timing of stopping the motor 61 is
Each will be different.

In this way, when each hook 46 passes under the blank material 12 and both motors 41 are stopped, the clutch 65 is actuated in the connecting direction based on the stop signal of both motors 61, and then both motors 61 are stopped. The motor 61 is driven in a direction opposite to that described above to pull in the chain 41, that is, to move the chain 41 to the right in FIG. As a result, the connecting shaft 64 integrally connected by the clutch 65
In this case, the rotations of both motors 61 are forcibly synchronized to pull both chains 41 at the same speed via the sprocket 66, and a hook connected to the tip of the chain 41 via the leading member 42 and the hook bracket 44 is connected to the tip of the chain 41. The end face of the blank material 12 is hooked on the arcuate surface 46 and moved to the right in FIG. At this time, the movable roller chute 5
8. Since the fixed roller chute 3 and the lifting roller chute 6 are located at the same height, the blank material 12 moves smoothly as the hook 46 moves, and finally the blank material 12 moves to the backing plate whose position has been adjusted in advance. The blank material 12 is moved until the end surface of the blank material 12 on the side opposite to the hook 46 comes into contact with the hook 46, and by this movement, the blank material 12 is transferred to a predetermined position on the lifting roller chute 6.

When the blank material 12 is transferred onto the lifting roller chute 6 in this manner, both motors 61 are stopped, the lift cylinder 10 is operated, and the piston rod 11 is driven in the advancing direction. As the piston rod 11 advances, the blank 12 is also lifted up via the lift plate 7 and the lifting roller chute 6, so that its upper end is located within the floating device 25. At this time, the volume of the pressure fluid supplied to the lift cylinder 10 is set to a predetermined amount, so that the upper end of the blank material 12 does not protrude from the floating device 25 in accordance with the amount of the blank material 12. has been done. Moreover, when the blank material 12 is raised in this way, the centering device 20
The pressing cylinder 22 is activated, and the pair of pressing plates 2
1 regulates both end surfaces of the blank material 12,
Lifting roller chute 6 of blank material 12
Centering at the top, ie, center positioning, is performed.

The blank material 12 whose center position has been determined in this way and whose upper end is placed in the floating device 25 is separated into pieces one by one by the action of the blank material separation mechanism 28 of the floating device 25. , blank material 1 at this top position
2 is adsorbed by the disk stack cylinder 32 and transferred to the blank material transfer device 30 side. This blank material transfer device 30 presses blank materials 12 one by one at predetermined intervals by the action of movable and fixed suction cups provided on a movable frame 33 and a fixed frame 31 in the same way as a normal blank material transfer device. It will be moved to the machine side and supplied.

Next, when all the blank materials 12 placed on the lifting roller chute 6 are carried out by the blank material transfer device 30, the lift cylinder 10
is activated and the lifting roller chute 6 is lowered, while the pair of motors 61 is again moved in the chain payout direction, and the stack of blank materials 12 still remaining on the movable roller chute 58 is lifted by the action of the hook 46 again. It is pulled onto the lifting roller chute 6 in the same manner as described above, and the floating device 2 is moved by the action of the lift cylinder 10.
5, and sequentially remove the blank material 12 one by one.
will be carried out. At this time, if continuous operation is to be performed, that is, in order to supply the blank material 12 on the lifting roller chute 6 to the floating device 25 without interruption, it is necessary to
As disclosed in the above publication, a holding pawl that can be rotated only in the upward direction may be provided at the lower part of the floating device 25.

When all the stacks of blank materials 12 on the movable roller chute 58 have been carried out onto the lifting roller chute 6 in this way, they are transferred onto the movable roller chute 58 by a detection signal from a detection means such as an optical sensor (not shown) or in advance. automatically according to the program in which you have entered the number of loads.
The cylinder 36 is actuated in the direction in which its piston rod 37 descends, and the empty movable roller chute 5
8 is lowered and stored in the magazine 55. At this time, a new blank material is placed on a movable dolly 52 different from the undulating dolly 52 on which the magazine 55 with the empty movable roller chute 58 lowered and stored is set, that is, on the movable dolly 52 located on the left side in FIG. 1
A magazine 55 carrying blanks 12 in a predetermined stack is set in advance while the blanks 12 are being carried out one by one.
A movable cart that supports a magazine 55 loaded with a new blank material 12 that is moved outward from a position facing the main body frame 1, that is, to the right in FIG. 52
is moved to a position facing the main body frame 1.
Furthermore, if this new blank material 12 has a different shape from the blank material 12, it is necessary to change the setting position of the floating device 25.
5 is moved away from above the main body frame 1 along the rail 24, and the other floating device 25, which has been set in advance along the shape of the new blank material 12, is moved onto the main body frame 1 and moves to the next blank material. The separation operation of the material 12 will be performed.

Thereafter, the blank material 12 is successively operated in the same manner.
is separated and fed to the press machine.

According to this embodiment as described above, the stack of blank materials 12 piled up to a predetermined height is not lifted up by slinging work as in the conventional method, so that each blank material 12 is not damaged.
Further, the stack of these blank materials 12 is mounted on a movable roller chute 58 that can be attached to and detached from the magazine 55.
Since the products are delivered in multiple stacks on top of each other, compared to the conventional process of supplying one stack at a time, the interval required for one supply can be extended, which simplifies logistics and improves work efficiency. can be improved. Furthermore, the operation of drawing the stack of blank materials 12 from the movable roller chute 58 via the fixed roller chute 3 onto the lifting roller chute 6 uses a hook 46 that can be raised and lowered, and a single raising and lowering of this hook 46 is detected. Since the retracting operation is performed by driving the pair of motors 61, it is sufficient that the stacks of blanks 12 are placed on the movable roller chute 58 at intervals within the range where the hooks 46 can be raised and lowered. Since the loading position is accurately regulated and there is no roller for loading, the loading can be easily controlled. Furthermore, since the pair of hooks 46 are driven by different motors 61, even if the blank material 12 is not a simple rectangle but has an irregular shape as shown in FIG. Since the driving of the motor 61 is stopped upon detection of a single up-and-down movement, the retracting movement can be performed without any problem. At this time, since the end surface of the hook 46 that comes into contact with the blank material 12 is formed in an arc shape, the hook 46 and the blank material 12 can always properly contact each other, and the retracting operation can be performed smoothly. Furthermore, since the retracting operation of the chain 41 by the pair of motors 61 is forcibly synchronized with the clutch 65 in the connected state, the rotation speed of the motor 61 can be controlled without the need for a special device, and the control circuit can be controlled. It's easy to do. In addition, the floating device 25
Since a plurality of mobile carts 52, that is, two moving carts 52 are provided, one floating device 2
5 or moving carriage 52 while the other floating device 25 or moving carriage 52 is being used.
2 setup operations can be performed, and work efficiency can also be improved from this point of view.

In the above embodiment, the chain 41 was used as the push/pull connection means, but the present invention is not limited to this, and a wire rope of relatively high rigidity, such as a wire rope wound around a drum in a winch, or a comparative Other means such as a highly rigid timing belt may also be used. Also, hook 46
As a hook undulation detection means for detecting undulations of
A switch 48 consisting of a proximity switch as shown.
However, the present invention is not limited to this, and a reed switch, optical switch, or other switch may be used. Further, the blank material moving means 69 is not limited to the above-mentioned structure, and may have other structures. For example, the hook 46 is not limited to a structure that rises and falls, but may be a structure that protrudes up and down. The means is not limited to the chain 41 and the motor 61, but may be a cylinder, a rack and pinion, etc., if space is available. Further, the number of the movable roller chute 58, the fixed roller chute 3 on the main body frame side, and the lifting roller chute 6 on the lift plate 7 in the above embodiment is not limited to the number in the above embodiment. It can be set as appropriate depending on the shape of. Furthermore, a clutch 65 connects the pair of motors 61.
does not necessarily need to be provided, and the motors 61 may be driven independently, but since the drive control to synchronize and rotate both motors 61 during the retracting operation is complicated, it is not necessary to provide the motors 61 as in the above embodiment. It is advantageous to provide the clutch 65 at Further, in the embodiment, the chain guide 40
Although a chain guide 40 is provided on the lifting table 38, the present invention is not limited thereto, and a chain guide 40 may be provided on each magazine 55. However, since a large number of magazines 55 are generally attached, the number of chain guides 40 also increases according to the number of magazines 55, which has the disadvantage of increasing the manufacturing cost of the entire device. Therefore, when there are a large number of magazines 55, it is cheaper to provide the chain guide 40 on the lifting table 38 as in the above embodiment;
5, the lifting device consisting of the lifting table 38 or the like may be omitted by providing it directly on the magazine 55.

[Effect of idea]

As described above, the present invention has the advantage that it is possible to provide a disk feeder that does not damage blank materials and can improve work efficiency.
