Description

The present invention relates to a lateral movement device for a gantry that can be laterally moved freely between chains for moving the gantry.

(Prior Art) For example, as a method of raising and lowering a gantry that moves in the vertical direction, it is quite common to suspend both ends of the gantry by a chain stretched in the vertical direction. In this method, a large number of pedestals are suspended from a chain at regular intervals, and are raised or lowered by moving the chain upward or downward.

(Technical problem) In the conventional lifting method, when any one of a large number of mounts is moved to a specific position, all the mounts in the moving direction of the mount must pass through the specific position. It is not possible to move any mount to this position.

Therefore, as a result of the research, the inventor of the present invention has found that if a plurality of chains are stretched and the gantry is delivered in each system chain, rational operation can be performed without unnecessary movement of the gantry. I thought about it.

It is an object of the present invention to provide a gantry lateral movement device that allows smooth movement including transfer between chains of a plurality of systems.

(Technical Means) The object is a plurality of sets of parallel chains stretched between a plurality of sets of sprockets, a movable roll provided on the chain plate via a bracket so as to be rotatable around a horizontal axis,
The moving roll passes through the inside, and a slit for taking out the bracket to the outside is provided in the moving direction, and a frame pillar on which the moving roll rolls and a wall on the side of the slit are approximately horizontal to the gantry side moved by the chain. A lock rail provided and a traverse roll rotatably provided on the bracket side around the vertical axis so as to be locked to the rail, and from one chain to an adjacent chain when the adjacent bracket is at the same position. This can be achieved by a configuration including a gantry and a lateral movement mechanism having a claw for engaging and disengaging the gantry for transferring the gantry.

The apparatus of the present invention configured as described above is equipped for horizontal movement of elevating pallets or the like in elevating type parking lots or warehouses or in smaller rotating (elevating) racks. can do.

(Example) Hereinafter, description will be given with reference to the drawings. 1 and 2 show a lateral movement device for an elevating pedestal, where 1 is a main body of the elevating pedestal device, 2 is a base portion thereof, and 3 and 4 are pillars standing upright in the rear portion thereof. 5 is a pedestal, which is a pallet portion 6 on which the object A to be lifted is placed
And a back plate 7 provided at its end, and a plurality of units are attached to the elevating mechanism 10 in a cantilever manner at required intervals.
Reference numeral 8a is a lateral moving wheel provided on the lower surface of the tip of the pallet portion, and 8b and 8c are guide wheels provided on the right and left inner portions of the pallet portion, which are in contact with the pillars 3 and 4 and the intermediate partition 4 '. 9 is the left and right pillars 3,
4 shows a hollow frame column standing upright between 4, 3, 4. Again 1
Reference numerals 1 ₁ , 11 ₂ , 12 ₁ , 12 ₁ , 12 ₂ , 13 ₁ , 13 ₂ , 14 ₁ , 14 ₂ are four pairs of upper and lower sprockets, which are mounted near the frame pillar 9, and the outer chain 15 is an outer sprocket 11 ₁ , The inner chain 16 is hung on 14 ₁ , 14 ₂ , 11 ₂ and the inner chain 16 is set on the inner sprocket 12 ₁ , 13 ₁ , 13 ₂ , 1
Since 2 ₂ are train-around, they Article 2 right when for example the left two rows of both chain 15 and 16 is increased is lowered lifting mechanism
Make up 10. A space S in which the gantry 5 is to be moved laterally by the lateral movement mechanism 40 is prepared in the lifting mechanism 10.

A side wall U-shaped bracket 18 is attached to a chain plate 17 of each chain 15 and 16, and four lifting and lowering rolls 20 rotatable around a horizontal axis are axially supported 20a on both sides of the bracket. Reference numeral 19 indicates a space interposed between the chain plate 17 and the back plate of the bracket. The chain and roll 20 pass through the hollow frame pillar 9 described above, and the end of the bracket 18 is exposed to the outside through a vertical slit 21 formed in the front surface of the frame pillar. The elevating roll 20 rolls along the inner walls on both sides of the slit, but in the illustrated example, the receiving frame 22 is provided in the frame columns on both sides of the slit so that the elevating roll 20 rolls in the roll receiving frame 22. . Horizontally movable rolls 23 rotatable around a vertical axis are respectively supported 24 above and below the tip of the bracket 18.
The illustrated lateral movement rolls 23, 23 are arranged to face each other. Further, a sub roll 25 for bearing a load, which is located between these rolls 23 and is rollable by lateral movement on the gantry side, is pivotally supported 26 on the bracket 18.

These rolls 23 and 25 constitute the lateral movement mechanism 40,
It engages with a locking rail 30 provided on the gantry 5 side. The locking rail 30 is a hook-shaped portion with which the upper and lower traverse rolls 23, 23 engage, respectively.
31 is provided up and down, and a groove-shaped portion 32 opened to the bracket side is provided between them, and further provided with a side plate 33 that forms a receiving groove for the traverse roll together with a mounting member and hook-shaped portion 31 on the gantry side. ing. It is desirable that at least two upper and lower locking rails 30 are horizontally provided on the pedestal back plate portion, 34 is an engaging ring provided at the end of the rail 30, 35 is an engaging claw that engages and disengages with the engaging ring.
Reference numeral 36 denotes a lateral movement chain to which the engaging claws 35 are attached, and has a length that extends from one chain of the elevating mechanism 10 arranged in parallel to the other chain. Reference numeral 37 denotes a chain / sprocket mechanism for driving the lateral movement chain 36.

The lifting roll 2 that can be attached via the bracket 18
0, traverse roll 23 and auxiliary roll 25 are all chains 15, 1
A large number of fixed rails 6 are fixed to 6 and locking rails 30 are provided on the pedestal 5 in accordance with the fixed rails. Inside, the bracket 18 parts of each chan 15, 16 are all lined up in the same position.

(Operation) In the lateral movement device of the present invention having the above-described configuration, the gantry 5 is laterally moved from the chain on either side to the chain on the other side. For example, when the gantry 5 on the upper left side of the hoistway is moved to the right side, the chain and sprocket mechanism 37 is activated by a signal from the control device, and the engaging claw 35 attached to the traverse chain 36 is attached to the engaging ring 34. It engages and moves the gantry 5 in the moving direction of the chain 36. At that time, the pedestal 5 is the back plate 7
Is in a state of being locked with the laterally moving rolls 23, 23 and the auxiliary roll 25 by the locking rail 30 provided on the locking rail 30, and when the rolls 23, 25 are rotated by being pulled by the engaging claws 35, the locking rail 30 is It rolls on each roll 23, 25 of the adjacent chain and moves further to transfer to the chain on the other side. The completion of this lateral movement is detected by a limit switch or other detecting means.

(Effect) Since the present invention is configured and operates as described above, the gantry can be freely moved between the chains of a plurality of systems in a direction substantially orthogonal to the tensioning direction, and the gantry is formed by the chuns. By combining movement and lateral movement by the lateral movement mechanism, it is possible to reach the target position from a certain position in the shortest time, eliminating unnecessary movement of the chain, and quickly moving any one of the many gantry to a specific position. It has the effect of being able to move.
