Abstract

PURPOSE:To prevent sections from damages due to grip, slide and drop by carrying out all operations of receiving the sections in a skid arm, transferring them to a temporary support mechanism and loading them on a pallet only by scooping up the section from below. CONSTITUTION:A skid arm 4 receives a section W carried by a conveyer 2 in the ascending process, while a spacer pocket 12 receives a spacer 16 so that the spacer 16 is inserted in the underside of the section W. Next, when the arm 4 is advanced to transfer the section W above a pallet bed 17, both ends of the spacer 16 received in this pocket 12 are opposed to a carrier plate 19 of a support lever 18 in a temporary support mechanism 7 attached to the pallet bed 17. Thereafter, the arm 4 is lowered to temporarily support the section W on the support lever 18 through the spacer 16. Finally, the arm 4 is retreated to lift the pallet 17 and the carrier plate 19 is retreated to the outside after the carrier plate 19 is transferred to the pallet side.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a shape material loading device, and relates to an aluminum shape material loading device.
It is used in the field of manufacturing mold materials (hereinafter referred to as mold materials).

(Prior Art) Conventionally, there have been methods for loading metal shapes conveyed from an extruder onto a pallet, either manually or automatically using power. In the latter automatic method, a predetermined number of shapes are gripped and transferred onto a pallet, and the gripped and transferred shapes are sequentially stacked on the pallet.

(Problems to be solved) In the conventional method, the manual method requires labor,
Needless to say, this method is time-consuming and has problems that impede efficiency improvement.

In the unidirectional dynamic method, it is necessary to detect and confirm the operating conditions when gripping and releasing the shape material, which takes time and is a bottleneck in increasing speed. In addition, there is a problem of damage to the mold materials due to gripping and sliding contact between the mold materials due to vibrations during transportation, etc., and when stacking the mold materials on a pallet, it is necessary to accurately detect the height of the mold materials that are already stacked. Because it is difficult to do so, the molds must be dropped from above the pallet or pressed against the molds that are already stacked, which can cause scratches and
There was a problem with the equipment's operation being unreliable.

(Means for Solving the Problems) However, the present invention is a device for transferring and loading the molded materials conveyed from an extruder onto a pallet via a skid arm, and in order to insert a spacer under the transported molded materials into the skid arm. In addition, a pallet stand is installed in front of the skid arm so as to be movable up and down, and a support mechanism for temporarily supporting the mold material via the spacer is attached to the pallet stand to constitute the model A loading device, It is something that tries to solve problems.

The skid arm is known as a member that repeats upward, forward, downward, and backward movements. The mechanism for inserting the spacer under the transfer profile is a spacer pocket provided on one side of the tip of the skid arm, and a spacer supply conveyor provided below the skid arm at right angles to the skid arm. It consists of spacer receivers that are provided on both sides of the conveyor in the direction of movement, and are movable up and down. When the skid arm rises, the upper spacer of the spacer receiver fits into the spacer pocket. is now inserted.

In addition, the support mechanism that temporarily supports the shape material through the spacer is
Consisting of multiple sets of support rods rotatably installed on both sides of the pallet stand (in the forward and backward directions of the skid arm),
A receiving plate for the end of the spacer is fixed to the upper end of the support rod. The support rod may further be movable up and down.

(Function) In the profile loading device having the above configuration, the skid arm receives the profile carried by the conveyor during the upward process.

At this time, the spacer is simultaneously inserted into the spacer pocket, and as a result, the spacer is inserted into the lower side of the mold material. Next, when the skid arm is advanced to transfer the molded material above the pallet table, both ends of the spacer that has been received in the spacer pocket and the receiving plate of the support rod in the temporary support mechanism attached to the pallet table face each other, Therefore, when the skid arm is lowered next, the profile is temporarily supported on the support rod via the spacer. Finally, when the skid arm is retreated and the pallet is raised, the shaped material supported by the temporary support mechanism is moved to the pallet side, and the supporting rod is rotated to move the receiving plate that was facing the end of the spacer outward. When the pallet is evacuated and the pallet is lowered, it returns to the initial state, and by repeating the same operation, it is possible to sequentially stack the shapes on the pallet.

However, in the above-mentioned device, the receiving of the profile material onto the skid arm, the transfer to the temporary support mechanism, and the stacking operation on the pallet are all operations in which the profile material is scooped up from the bottom to the top. Moreover, since there is no need for an operation such as gripping the mold materials, the mold materials can be loaded onto a pallet without causing damage to the mold materials due to gripping, adhesive bonding, dropping, or pressing.

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

FIG. 1 is a diagram showing the entire apparatus, and numeral 1 in the figure is a saw gauge table composed of a rolling conveyor, which is a table in which shapes cut to a fixed size are sequentially fed and brought to the saw gauge table. Belt conveyors 2.2 are arranged in parallel at right angles to the table 1 at a predetermined interval so that a predetermined number of shapes on the saw gauge table 1 can be transferred in the direction of the arrow 3.

Now, the profile loading device of the present invention is based on the belt conveyor 2.
．． This device loads the molded materials transferred in step 2 onto a pallet, and includes a skid arm 4, a mechanism 5 for inserting a spacer into the lower side of the molded materials, a pallet stand 6, and a support mechanism 7 for temporarily supporting the molded materials. It consists of

The skid arm 4 is an arm installed parallel to one side of the front end of the belt conveyor 2.2, and is raised, advanced, and lowered as shown by arrows 8, 9, 10, and 11 via a drive mechanism (not shown). , is set to retreat.

A spacer pocket 12 having a U-shaped cross section is fixed upward on the outside of the front end of the skid arm 4, and the spacer is attached to the molded material by the spacer pocket 12 and a chain conveyor 13 installed below the skid arm 4. A mechanism 5 for insertion into the lower side is configured. That is, a chain conveyor 13 is installed at right angles to the skid arm 4, and pawls 14 and 14 are provided on the chain conveyor 13 in accordance with the installation interval of the skid arm 4, and the spacers are provided on both sides of the chain conveyor 13 in the direction of movement. A spacer receiver 15.15 is installed on the lower side of the pocket 12 so as to be movable up and down.

The chain conveyor 13 and spacer receiver 15.15 that constitute this spacer insertion mechanism 5 are driven in a constant relationship with the movement of the skid arm 4, and when the skid arm 4 is raised, the spacer receiver 15.15 is moved upward. A spacer 16 is associated to fit within the spacer pocket 12. When the spacer 16 is moved to the skid arm 4 side, the chain conveyor 13 starts driving in order to prepare the next spacer 16, and stops when the spacer 16 is conveyed below each skid arm. During this time, the spacer receiver 15 is lowered, and when the chain conveyor 13 stops, it rises and the spacer receiver 15 is lowered.
A spacer 16 is supported on the spacer 5. On the other hand, the skid arm 4 moves forward, descends, and retreats during the above operation, and when it next ascends, the spacer pocket 12
The spacer 16 supported on the spacer receiver 15 can be removed from the spacer receiver.

A pallet stand 6 on which a pallet 17 is placed is installed in front of the skid arm 4 so as to be movable up and down.

Further, on both sides of the pallet table 6 in the longitudinal direction (in the forward and backward directions of the skid arm 4), there are spacers 16 that are carried in the spacer pockets 12 of the skid arm 4.
A support rod 18.18 is rotatably provided at a position below both ends of each of the support rods 18.18, and the upper end of the support rod 18.18 is provided with a support rod 18.18 that receives the spacer 16 in the spacer 12 so as to be opposed to its upper end. Plate 19.19 is fixed.

The support rods 18.18 and the receiving plates 19.19 are mechanisms that temporarily support the shapes transferred above the pallets 1 to 17 by the skid arm 4, and when the skid arm 4 is moved forward and then lowered. Support rod 18.18 catch plate 1
9. Spacer 1 in spacer pocket 12 on top of 19
The end of 6 can be placed on it. Further, the spacer 16 supported by the temporary support mechanism can be moved to the pallet 17 side by raising the pallet stand 6.
When the pallet stand 6 is raised, the support rods 18.18 are rotated and the receiving plate 19.19 is turned to the side. When the pallet stand 6 is lowered, the spacer 16 moved to the pallet 17 side is It can be lowered together with 17 and does not return to the temporary support mechanism side.

Referring to FIGS. 2 to 7, the manner in which the shape material W is loaded by the shape material loading device of the above embodiment will be described as follows. When a predetermined number of shapes W are transferred onto the saw gauge table 1, the belt conveyor 2 is driven and the shapes W are conveyed to the front end of the belt conveyor 2 (FIG. 2). At this time, the skid arm 4 is in the lowered and retreated position, and the spacer 16 is placed on the spacer receiver 15, 15 in the spacer insertion mechanism.

Next, as shown in FIG. 3, the skid arm 4 rises as shown by arrow 8, receives the mold material W on the belt conveyor 2 on the skid arm 4 side, and receives the spacer 16 in the spacer pocket 12. I'll take it.

The shaped material W and spacer 16, which have been received in the above manner, are carried above the pallet table 17 by the advance of the skid arm 4 in the direction of arrow 9 (FIG. 4).

At this stage, as described above, the spacer insertion mechanism starts the next preparatory operation.

Next, the skid arm 4 is lowered and the spacer receiver 15.15 of the spacer insertion mechanism is raised (FIG. 5). As the skid arm 4 descends, the spacer 16 carried by the skid arm 4 rests on the receiving plate 19.19 fixed to the support rod 18 of the temporary support mechanism 7.
Further, the shape material W is placed on the spacer 16 one level above the receiving plate 19, and is temporarily supported in this state.

Subsequently, the skid arm 4, which has released the profile W and the spacers 16 and 16, retreats as shown in FIG.

While returning to the initial state, the pallet stand 17 is raised via the pallet stand 6. On the other hand, as the pallet stand 6 rises, the pallet 17 lifts the shape material W temporarily supported by the temporary support mechanism 7, with spacers 16 and 16 placed underneath.

Next, as shown in FIG. 7, by rotating the support rod 18 of the temporary support mechanism 7 to release the receiving plate 19 to the outside and lowering the pallet stand 6, one cycle of the loading operation of the shapes W is completed. , and thereafter, by repeating the same operations, the shapes W are sequentially loaded onto the pallet 17.

When the number of loading stages reaches the specified number, pallet 17
can be moved in the direction of the arrow 20, another pallet 17 can be set on the pallet stand 6, and the same work can be continued.

In the above, the receiving plate 19 between the belt conveyor 2 and the skid arm 4, between the skid arm 4 and the temporary support mechanism 7
．． 19 and between one of the receiving plates 19.1 and the pallet 17, the shape material W is transferred by lifting the shape material W from the lower side at any stage. There is no risk of the mold material W falling or being pushed around, and it is possible to eliminate damage to the mold material W during transfer.

(Effects of the Invention) As explained above, according to the present invention, there is no need to grip the shapes when loading the shapes, so there is no risk of damaging the materials due to gripping, and the work speed is increased. There is also an effect that can be done.

Moreover, since all the handling of the mold material is carried out by lifting it from the lower part and transferring it, there is an advantage that there is no damage caused by dropping or pressing.

In addition, the mechanism of the device is quite simple, and the operation of the device is stabilized, reliability is high, and the operating rate is improved due to fewer troubles due to scratches and fewer troubles in feeding the mold material.

However, since it is possible to provide a device that can maintain the quality of the mold material at high speed, it is effective in manufacturing.
