Description

[Detailed description of the invention] This invention transports blanks picked up by a vacuum cup to a loader by a day-stacking conveyor, and drives the day-stacking conveyor in the day-stacker where the blanks are supplied into the press by the loader. It is related to the device.

Conventionally, this type of day stacking conveyor is driven by a motor that operates a clutch/brake on and off.

For this reason, there may be a time lag with the loader drive due to slippage, variations, timing deviations, clutch/brake wear, etc. caused by intermittent use of the clutch/brake during high-speed operation, and blanks may not be conveyed correctly to the loader. .

The present invention has been made in view of the above circumstances, and its object is to provide a drive device for a de-stacking conveyor in a de-stacker, which allows the de-stacking conveyor to be driven in synchronization with the loader.

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a press-side drive shaft connected to a drive section of the press via a gear 2, and the press-side drive shaft 1 is connected to a loader-side drive shaft 4 via a coupling mechanism 3. The loader side drive shaft 4 has a bevel gear mechanism 5 and a shaft 6.
The gear 7 meshes with a gear 9 of a camshaft 8, and a cam 10 is fixed to the camshaft 8.

A cam follower 13 provided at one end 12a of a first lever 12 fixed to one end of the rotating shaft 11 contacts the cam 10, and a second lever 21 is fixed to the other end of the rotating shaft 11. The swinging end of the two levers 21 is connected to a carrier 23 of the loader A via a rod 22. The carrier 23 is a guide rod 23
It can freely reciprocate toward the press along line a. Further, a rack member 25 is pivotally connected to the other end side 12b of the first lever 12 via a link 24, a pinion 27 provided on a shaft 26 meshes with the rack rod 25, and the shaft 26 is connected to a gear 28, a gear 29, is connected to a shaft 31 via a one-way clutch 30, and the shaft 31 is provided with a friction brake 32.

B is a stacking conveyor that is installed continuously with the loader A, and a plurality of unit belts 37, each of which has a belt 36 wound around a drive roller 34 and a forward roller 35 provided on a drive shaft 33, are arranged side by side at intervals. A vacuum cup 38 is provided between adjacent belts 36 and 36 and is moved up and down by a lifting mechanism (not shown).
Belt 3 with a built-in magnet that picks up the
6.

A gear 42 provided on a rotating shaft 41 meshes with a gear 40 provided on each drive shaft 33, and the rotating shaft 41 is connected to the shaft 31 via a sprocket 43, a chain 44, and a sprocket 45.

On the discharge side of the day stacking conveyor B, a pair of oil coater rollers 46, 46 which are in pressure contact with each other are provided over the entire length in the width direction. It is connected to the rotating shaft 41 via the rotating shaft 41 .

51 is a jaw (clamp claw) provided on the carrier 23.

When the press is driven, the cam 10 rotates, the first lever 12 and the second lever 21 swing, and the second
By swinging the lever 21, the carrier 23 is reciprocated toward the press. Thereby, the jaw 51 is reciprocated in synchronization with the press.

On the other hand, due to the swinging of the first lever 12, the rack lever 25
is moved up and down, and the shaft 26 is rotated forward and backward via the pinion 27. However, this rotation is transmitted to the rotating shaft 41 via the one-way clutch 30, etc., so the rotating shaft 41 rotates intermittently in one direction. In order to do this, the belt 36 is rotated in one direction intermittently in synchronization with the carrier 23.

Therefore, the blank material 39 adsorbed on the belt 36 is transferred to the loader A through the oil coater rollers 46 and 46 in synchronization with the supply of the blank material by the loader A.
The materials are sequentially conveyed to the side and sequentially supplied into the press by the jog 51.

The present invention is as described above, and when the press side drive shaft 1 rotates, the cam 10 moves the first and second levers 1.
2 and 21 swing, the carrier 23 of the loader A is reciprocated by the second lever 21, and the shaft 26 is rotated in forward and reverse directions by the first lever 12, and the forward and reverse rotation is controlled by the one-way clutch 30. As a result, only forward rotation is transmitted to the rotating shaft 41, and the belt 36 is rotated in only one direction.

Therefore, the carrier 23 of the loader A and the belt 36 of the day stacking conveyor B can be driven in synchronization with the press, and the blanks picked up by the belt 36 are conveyed to the loader A, which then supplies them into the press. can.

Further, the blank material is attracted by the vacuum cup 38 and lifted up, and is attracted by the belt 36 having magnetic force, and by rotating the belt 36, the loader A
Since it is transported towards the target, even thin and weak blank materials can be transported reliably.
