Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a transfer mechanism for a plate-like object, that is, a mechanism for horizontally transferring a plate-like object that has been vertically fed as it is.

(Prior Art and its Problems) As this type of transfer mechanism, there is Japanese Utility Model Application Laid-Open No. 59-133522 previously proposed by the present applicant. That is, the vertical feed roll and the horizontal feed roll are arranged to face each other in the vertical direction, and the plate-like object on the vertical feed roll is held by the horizontal feed roll and the upper track of the endless belt for horizontal feed that is pushed up by the support table. It is something to send.

However, with this mechanism, although there is no hindrance to normal plate-shaped object transfer, it is necessary to adjust the distance between the lateral feed roll and the support table by the thickness of the single plate when laterally feeding. That is, if the distance between the lateral feed roll and the support table is narrow, the veneer cannot pass, and if it is too wide, the veneer cannot be laterally fed.

(Object of the Invention) In view of the circumstances as described above, the present invention provides a plate-like object transfer mechanism capable of laterally feeding a plate-like object without adjusting the plate-like object feeding mechanism according to the thickness of the plate-like object. That is the purpose.

(Structure of the Invention) Therefore, the transfer mechanism of the plate-like object according to the present invention has a plurality of vertical feed rolls for loading the plate-like object into the transfer area and a vertical feed roll extending in a direction intersecting with the vertical feed rolls. A plurality of lateral feed rolls located above the rolls, an endless belt for lateral feed arranged between the plurality of vertical feed rolls that can be driven to rotate in the same direction as the transfer direction by the lateral feed rolls, and a lateral feed roll A plurality of divisions that are arranged in alternating orbits of the endless belt for lateral feed and that can move up and down so that the upper orbit of the endless belt for lateral feed is pushed up above the level of conveyance by the vertical feed rolls at the elevated position. A roller and a drive mechanism for driving each of the division rollers up and down. The plate-like object conveyed to the upper surface of the vertical feed roll is taken into the transfer area by the rotation of the vertical feed roll, and then each division is performed by driving the drive mechanism. Rising roller By doing so, the upper track of the horizontal feed endless belt is raised above the level of conveyance by the vertical feed rolls, and the upper track of the horizontal feed endless belt and the plate-like object are staggered between each horizontal feed roll and each split roller. It is configured to be held and to carry out the plate-like material in the lateral direction by the endless belt for lateral feeding, which is driven to rotate.

(Embodiment of the Invention) In the illustrated transfer mechanism, a pair of left and right lateral feed rolls 2a and 2b are arranged above and below a plurality of longitudinal feed rolls 1 ... A pair of endless belts 3,3 as a pair of endless belts for lateral feed and a longitudinal feed roll 1 ...
Are placed between.

The vertical feed rolls 1 ... Are constantly rotated in the arrow A direction by contact with an endless belt (not shown), and the horizontal feed rolls 2a are always rotated in the arrow B direction by a winding belt (not shown). The lateral feed roll 2b is free to rotate.

The endless belts 3, 3 are wound between a rotating roll 3a and rotating rollers 3b, 3b arranged near both ends of the longitudinal feed roll 1 in the axial direction, and are constantly wound in the direction of arrow C. Further, the orbit above it is usually set to be lower by a predetermined amount than the upper surface of the vertical feed roll 1, that is, the vertical feed transport level of the plate-like material by the vertical feed roll 1.

A plurality of split rollers 5 are provided between the upper and lower tracks of each endless belt 3.
Positions where a, 5b, 5c are different from the transverse feed rolls 2a and 2b alternately, that is, the order of the division roller 5c, the transverse feed roll 2b, the division roller 5b, the transverse feed roll 2a, and the division roller 5a according to the transfer direction of the plate-like material. The upper and lower tracks of the endless belt 3 are pushed up by the divided rollers 5a, 5b, and 5c so that the upper rollers are vertically fed and conveyed by the vertical feed roll 1 in the vertical feeding conveying level. Plate-like object Y on the orbit above it
Can be moved up and down so as to press against the lower surface of the lateral feed rolls 2a and 2b.

The split roller 5a is connected to an air cylinder 8 via an arm 6 and a rod 7, and can be moved up and down according to the operation of the air cylinder 8. Bracket 9 for air cylinder 8
The arm 6 is fixed to the body frame via the arm 6, and the arm 6 is connected to the arm 13 via the arm 10 and the shafts 11 and 12. The arm 13 is connected to an arm 15 rotatably fixed to a bracket 14, and the arm 15 has a split roller 5b.
Is rotatably fixed. Shaft 11 and shaft 12
A spring 16 is wound between them, and the arm 13 is urged toward the split roller 5c. And the air cylinder 8
When the rod 7 is lifted by the operation of, the split roller 5a is lifted by the swing of the arm 6, the shaft 11 is moved to the turning roll 3a side, and the split roller 5b is also lifted.

The split roller 5c is connected to an air cylinder 19 via an arm 17 and a rod 18. The air cylinder 19 is fixed to the main body frame via the bracket 20, and the arm 17
The end of is connected to a shaft 23 via an arm 21. A spring 25 is wound around the shaft 23, and the tip end side of the arm 21 is biased toward the split roller 5c side. When the rod 18 moves upward due to the operation of the air cylinder 19, the split roller 5c rises and pushes up the upper track of the endless belt 3 to move the plate-like object Y on the upper track to the lower surface of the transverse feed rolls 2a and 2b. Operates to press.

In addition, on the frame 26 bridged between the support frames 4,
A roller 29 connected to the rod 28 of the air cylinder 27 is arranged, and is configured to come into contact with the tip of the plate-like object moving on the vertical feed roll 1. An air cylinder 30 is fixed to the frame 26, and a pressing roll support mechanism 31 is fixed to the support frame 4.

The support mechanism 31 has pressure rollers 33 and 34 on both sides of a frame 32, and a belt 35 is wound between the pressure rollers 33 and 34.
The center of the frame 32 is connected to the cylinder via a shaft 36, arms 37 and 38, and a rod 39. For this reason,
When the rod 39 contracts due to the operation of the air cylinder 30, the arm
The frame 32 is maintained in a substantially horizontal state by the swinging of 37 and 38, and the plate-like object can be carried out by the belt 35 and the endless belt 3.

(Operation of the device) In the transfer mechanism configured as described above, the air cylinders 8, 19
When the rod is compressed and the rod 38 of the air cylinder 30 is extended, and the roller 29 is moved downward to introduce the plate Y into the upper surface of the vertical feed roll 1,
The plate-like material Y is sequentially introduced into the transfer area by the rotation of the vertical feed roll 1. When the tip of the plate-like object Y comes into contact with the stopper, a micro switch (not shown) provided on the stopper is actuated to drive the air cylinders 8, 19, 27, 30 in reverse rotation, and the rods 7 of the air cylinders 8, 19 are driven.・ As 18 expands, rods 28 and 39 of air cylinders 27 and 30 contract. As a result, the arms 6, 15, 17 swing and the arms 37, 38 swing, and the split rollers 5a, 5b, 5c move upward to lift the upper track of the endless belt 3. At this time, the roller 29 moves upward and the frame 32 of the support mechanism 31 is maintained in the horizontal state.

By the upward movement of the division rollers 5a, 5b, 5c, the upper track of the endless belt 3 is pushed up above the upper surface of the vertical feed roll 1 (that is, the vertical feed conveyance level), and the plate-like object Y is supported on the upper surface thereof. The plate-like object Y is pressed against the lower surface of the lateral feed rolls 2a and 2b. As a result, the upper track of the endless belt 3 and the plate-like object Y are separated by the divided rollers 5a, 5b, 5c and the lateral feed rollers 2a, 2a.
The plates Y are alternately sandwiched by b and the plate-like object Y is in a wavy state and is laterally fed as the endless belt 3 is driven to rotate. At this time, the tip end side of the plate-like object is sequentially carried out in the lateral direction as the belt 35 of the support mechanism 31 moves.

In this way, the upward trajectory of the endless belt 3 is raised by the dividing rollers 5a, 5b, 5c located at positions different from the transverse feed rollers 2a, 2b, so that the plate-like object Y on the upper trajectory is moved upwards of the endless belt 3. By being configured to be pressed by the lateral feed rollers 2a, 2b and laterally conveyed (transferred) around the endless belt 3, the plate-like material is prevented from being damaged due to dance or floating, and is stably transferred. And the split rollers 5a, 5b,
The distance between the 5c and the feed rollers 2a, 2b does not have to be a distance for sandwiching the plate-like object with a predetermined pressing force, and therefore the amount of rise of the split rollers 5a, 5b, 5c (endless belt 3
It is possible to convey without re-adjusting the ascending amount of the upper track).

(Effect of the Invention) According to the transfer mechanism of the plate-like object according to the present invention as described above, when the plate-like object is laterally fed, the endless belt is alternately held by the split roller and the lateral feed roll in a staggered state. Since the plate-shaped object is laterally fed in a wavy state, damage can be prevented and stable transfer can be performed, and plate-shaped objects with different plate thicknesses can be adjusted without adjusting the horizontal folding mechanism according to the thickness. It can be smoothly fed laterally.

That is, it is possible to perform transfer of plate-like objects having a plurality of plate thicknesses without adjusting the plate thicknesses, and stable and efficient transfer operation can be performed.
