Even if you try to transfer the material loaded with
As shown in the figure, the material hits the lifting plate a, making it impossible to transfer.

Therefore, the materials on the transport trolley must be manually transferred onto the lifting plate a, which makes it difficult to save labor and improve efficiency, and manual transfer of materials disrupts the queue, so it is not possible to manually transfer the materials onto the lifting plate a. When feeding, it causes positional discrepancies,
Furthermore, if there is a height discrepancy between the lifting plate a and the material feeding surface of the processing machine, there is a problem in that the material gets stuck on the lifting plate a or the feeding surface of the processing machine, impeding take-out and feeding. was there.

The present invention was developed in order to solve this problem.A lifting plate is attached to the base by a link of the same length, with the center intersection pivoted, pivoted at one end, and slidable at the other end. By connecting the hoisting cable wrapped around the upper machine, the lowering limit of the lifting plate is lower than that of the cart, making it possible to move the material loaded on the cart onto the lifting plate, saving labor and improving work efficiency.

34 is a processing machine that feeds the material 4 from the material feeding surface 35 to the lifter of the present invention, or feeds the material 4 from the lifter to the feeding surface 35.

Next, the operation of the material feeding and feeding device for woodworking according to the present invention will be explained.

When transferring the material 4 loaded on the bifurcated transport cart 30 to the lifting plate 3 of the lifter and feeding it one by one to the feeding surface 35 of the material 4 in the processing machine 34, the electric hoist A is used to hoist the material 4. When the cable 21 is unwound and the lifting plate 3 is lowered, the same-length links 5.5 are collapsed, and the lifting plate 3 is lowered in a horizontal state, and the weight is placed on the base frame 1 as shown in Figure 4 of the drawing. Since the lifting plate 3 is lowered than the cart 30, in this state, if the cart 30 is delivered with the lifting plate 3 in its two forks, the material 4 loaded on the cart 30 will be lower than the lifting plate 3. When the electric hoisting machine A winds up the hoisting cable 21, the same-length links 5, 5 rise and lift the lifting plate 3 in a horizontal state, so that the bogie 30 The material 4 on top is moved there by the lifting of the lifting plate 3. At this time, the screw shaft 11 is raised and lowered by operating the adjustment nut 14, and the height of the material guide rollers 24, 24 is adjusted to the height of the material guiding rollers 24, 24 in the processing machine 34. After matching the height of the material feeding surface 35, the electric hoist A is activated by the foot switch 23, and when the lower surface of the uppermost material 4 matches the height of the guide roller 24.24, the foot switch is activated. 23, the operation of the electric hoist A is stopped, the lifting plate 3 is stopped, and the material 4 in the uppermost stage is manually pushed out. Since it is sent to the surface, along with this,
By stepping on the foot switch 23, raising and lowering the lifting plate 3 by the thickness of one piece of material 4, and then manually feeding the material 4 toward the processing machine 34, the material 4 on the trolley 30 can be raised and lowered. Board 3
In response to this, the operation of feeding the sheets one by one to the processing machine 34 starting from the top one is performed efficiently.

In addition, when the materials 4 sent one after another from the feed surface 35 of the processing machine 34 are received and stacked on the lifting plate 3 and transferred to the cart 30 when the required number of stacks is reached, the lifting plate 3 is moved from the processing machine. The initial position is determined so that its upper surface is aligned with the guide rollers 24, 24, which are at the same height as the feed surface 35 of the processing machine 34, and the material is guided from the feed surface 35 of the processing machine 34 to the guide rollers 24, 24. Each time the material 4 is sent out onto the lifting plate 3, the foot switch 23 is operated and the electric hoist A
If the lifting plate 3 is operated in the downward direction of the lifting plate 3 and the lifting plate 3 is lowered by the thickness of one sheet of material 4, the materials 4 to be delivered are stacked on the lifting plate 3, and the lifting plate 3 is moved to the base frame. 1, the material 4 supported by the lifting plate 3 is transferred onto the cart 30 placed so as to sandwich the lifting plate 3, so if the cart 30 is pulled out at this time, the material 4 is sent out from the processing machine 34. The operation of stacking and taking out the materials 4 is also performed efficiently.

As mentioned above, the woodworking material feeding/discharging device according to the present invention can lower the elevating plate until it overlaps the base frame, making its height lower than that of the trolley, so it is possible to lower the height of the elevating plate until it overlaps with the base frame. When a transport cart of the shape of the shape is fed out so as to sandwich the elevating plate, the material on the cart is positioned on the elevating plate and is transferred thereto as the elevating plate rises. If the material is pushed out one by one while the elevating plate is raised intermittently, the operation of receiving the stacked material from the cart and feeding it to the feeding surface of the processing machine can be performed efficiently with little effort. If the plate is placed at the height of the feed surface of the processing machine and the elevating plate is lowered intermittently by the thickness of the material each time the material is fed from the feed surface of the processing machine, the material to be sent out can be stacked on the elevating plate. The removal of the material to be transferred to the trolley afterward is also carried out efficiently with only a few hands, so it has a great effect on labor saving and efficiency in the work of feeding and taking out the material.

A material guide roller is provided on the top of the support frame provided on one side of the base frame so that it can be raised and lowered.If the height of this guide roller is set to match the material feeding surface of the processing machine, the material can be fed in or out. Even if there is a slight difference in height between the position and the feeding surface of the processing machine, the guiding action of the rollers allows the material to be fed in and taken out smoothly without any jamming.

Since an electric hoist is used as a means for raising and lowering the lifting plate, unlike conventional products that use hydraulic cylinders with attached hydraulic units, it can be manufactured at an extremely low cost, maintenance costs are low, and only one end of the lifting plate is connected to the lifting cable. However, this elevating plate is connected to the base frame by a link of the same length that pivots at one end and slides at the other end, which is pivoted at the central intersection, so the elevating plate is always in a horizontal state due to the action of the link of the same length. It also has the unique effect of holding and raising and lowering materials, stacking materials, and delivering the stacks in a stable and orderly manner.
