Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for arranging a predetermined number of plate materials on a conveyor at equal pitches to form one block and conveying a large number of blocks at regular intervals.

This type of intermittent conveying device is used in the manufacturing process of fences and balcony decks to arrange a predetermined number of planks at equal intervals and convey them all at once over the required distance while keeping the intervals constant. As shown in the figure, a box motion bar 7 movable in the front-rear and up-down directions is installed on the side of the two parallel chain conveyor 6 that receives both ends of the plate material 1.
As shown in Fig. A, first, the plate materials 1 are fed one by one to the chain conveyor 6 and fed in pitch, and when a predetermined number of the plate materials 1 are lined up on the chain conveyor 6 at an equal pitch, they are fed as shown in the loss chart. The box motion par 7 is raised as shown in FIG.
As shown in Figure 2, the bar 7 is lowered to a predetermined (next process) position 8, and as shown in Figure E, the bar 7 is moved backward to complete one cycle of box motion.

However, the conventional method shown in FIG. 1 has the problem that the box motion mechanism is significantly more expensive than a belt conveyor or chain conveyor, and that it is not possible to achieve a large bulk conveyance distance.

The present invention aims to solve the above problems.

Hereinafter, the present invention will be described in detail with reference to the embodiment diagram shown in FIG. , a pair of belts or chains 3a, 3
A short transshipment conveyor 3 consisting of the above-mentioned material B is provided, and an elevating device (not shown) is provided to move the transshipment conveyor 3 up and down. A board material supply device 4 that supplies the board materials 1 one by one, and a belt or chain 3 of the transshipment conveyor 3 each time the board material 1 is supplied.
A and 3b are provided with a pitch feeding device (not shown) that feeds the plates 1 by one pitch, and a predetermined number of plates 1 are transferred to the reloading conveyor 3.
By lowering the transshipment conveyor 3 at the time when the plate materials 1 are supplied to the conveyor 2 for bulk conveyance.

The plate material supply device 4 consists of belt conveyors 4a, 4b and a stopper bar 40, and the reloading conveyor 3 and the bulk transport conveyor 4 are provided with attachments 5 for regulating the interval between the plate materials 1 to a constant value.

FIG. 3 explains the operating state of the device of the present invention. First, as shown in FIG. When the board materials 1 for blocks are lined up on the reloading conveyor 3, the reloading conveyor 3 is lowered and transferred to the bulk transport conveyor 4 as shown in Figure C. Then, the bulk conveyor 4 intermittently conveys the required distance.

In this example, one block of plate material is attached to the deck base material at the end of the bulk conveyor 4, and one block of plate materials 1 is supplied to the bulk conveyor 4. Each block is intermittently fed with a predetermined interval between blocks.

The present invention is constructed as described above, and since the reloading conveyor 3 has the functions of both pitch feeding and reloading of the plate materials 1, the bulk conveyor 4 can be configured with an ordinary belt conveyor or chain conveyor. This eliminates the need for a box motion mechanism, which not only reduces equipment costs, but also enables long-distance bulk conveyance, and the conventional box motion bar for bulk conveyance can only move one block at a time. However, according to the present invention, there is an advantage that a large number of blocks can be transported by providing intervals between the blocks.

Furthermore, in the present invention, the starting end of the reloading conveyor 3 for arranging the plate materials 1 at a constant pitch is aligned with the starting end of the bulk transport conveyor 2, so the length of the reloading conveyor 3 can be reduced to the minimum necessary length. Moreover, since the short conveyor 3 for reloading is raised and lowered up and down by the lifting device, the lifting force is small, and the lifting device can be made smaller and power saving can be achieved.
