Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an automatic tatami stacking machine with a reversing device for use in equipment that produces tatami mats in large quantities.

[Prior Art] A completed tatami mat has a handle for transportation on the back side. For this reason, when tatami mats are stacked and stored, the front sides of adjacent tatami mats touch, and the back sides touch, so that the top side is front, back, front, back, front, back...
The sheets must be stacked one by one in reverse order, alternating with each other. If you don't do it this way,
The handle leaves marks on the tatami mat.

Conventionally, the stacking was done mainly by hand as described above.

There are also mechanical devices, but they are large, expensive, and require a large amount of space.

[Problems that the invention aims to solve] This invention aims to provide a semi-automatic tatami stacking machine that stacks tatami mats so that the upper side of the tatami mats is stacked alternately in order: front, back, front, back. This allows tatami mats to be stacked up without the need for human labor.

[Means for solving the problem] The automatic tatami stacking machine with a reversing device according to this invention is an automatic tatami stacking machine equipped with a lift mechanism 15 that lowers the thickness of one tatami every time it is stacked. Abutment 1 on the feed side of the machine
2, two mutually independent rotation shafts 1a, 1b are horizontally supported on the same axis on the upper front surface of the support base 12, and the L-shaped swing frames 2a, 2b are mounted on each rotation shaft 1a, 1b. While fixing the tips of the long sides of the swinging frame 2a,
2b is configured to rotate between the forward direction and the diagonally forward downward direction, and the L-shaped swing frames 2a, 2b are provided with swing baskets 7a, 7b at the corners to receive the long sides of the tatami.

[Example] 10 is a sewing machine, and 11 is a foot roller arranged on the delivery side of the sewing machine 10.

Reference numeral 12 designates a support stand arranged at an appropriate interval on the exit side of the sewing machine, and reference numeral 13 represents a feed roller provided on the support stand 12.

There are two independent rotation shafts 1 on the front upper part of the support base 12.
a and 1b are arranged on the same line, and the ends of the long sides of the L-shaped swing frames 2a and 2b are fixed.
Crank 4a, 4 rotated by motor 3a
The lower ends of connecting rods 5a, 5b are connected to b, and the upper ends of connecting rods 5a, 5b are at the highest and lowest positions of L-shaped swing frames 2a, 2b, and cranks 4a, 4b are controlled by limit switches. The rotation is now stopped.

Swivel baskets 7a, 7b for receiving the long sides of the tatami mats are attached to the corners of the swing frames 2a, 2b by spindles 14, and the pivot baskets 7a, 7b are pressed against stoppers by springs 8a. There is.

When the tatami mat 16 is placed on the lift mechanism 15 provided adjacent to the support base 12, the optical sensor 17 is cut off, and the lift mechanism 15 is lowered to the position where the electricity is turned on again. In the lift mechanism 15, the rotation of a motor 19 attached to a roof plate on a support column 18 is transmitted to a chain 21 via a chain wheel 20, and the lift mechanism 15 moves up and down together with the chain 21.

[Function] A tatami sewing machine is installed as a pre-process on the feeding side of the automatic tatami stacking machine.

When the operation button 22 is pressed, both swing frames 2a and 2b are lowered. Then, the swing frames 2a, 2b and the sewing machine 10
A gap A is maintained between the sewing machine and the sewing machine, allowing the worker to operate the sewing machine 10.

On the sewing machine 10, the back side of the tatami mat 16 is facing upward.

First, the procedure for turning over the tatami 16 on the sewing machine 10 and loading it onto the lift mechanism 15 so that the upper side is the front side will be described.

When the operation button 23 is pressed, the first swing frame 2a is raised and the second swing frame 2b is lowered.

A worker who has entered between the second swing frame 2b and the sewing machine 10 places the tatami mat 16 diagonally and only one end on the roller 33 of the first swing frame 2a, as shown in FIG.

The worker steps out from between the second swing frame 2b and the sewing machine 10 and presses the operation button 23. Then, the second swing frame 2b rises and the timer B starts operating.

As shown in FIGS. 3 to 5, the other end of the tatami mat 16 is placed on the roller 34 of the second swing frame 2b.

After the set time of the timer B has elapsed, both swing frames 2
a and 2b are lowered, and the tatami 16 falls diagonally downward and backward, as shown in FIGS.
a and 7b, and timer C starts operating.

Manually raise the upper end of the tatami mat 16 using the rotating baskets 7a and 7b as fulcrums and pass it through a vertical plane, so that the upper end of the tatami mat is leaning diagonally backward and upward, as shown in Figures 8 and 9. .

By the operation of the timer B, both swing frames 2a,
2b rises and is supported by the feed roller 13 on the abutment 12 as shown in FIGS. 10 and 11,
It is supported in a slightly inclined state toward the rotating baskets 7a and 7b.

The tatami 16 is manually pushed onto the lift mechanism 15.

When the tatami mat 16 is placed directly on the lift stand or at a predetermined position on the tatami mats already stacked on the lift stand, the lift stand is lowered by the height of one tatami mat by the optical sensor 17.

Next, a working procedure for loading the tatami mat 16 on the sewing machine 10 onto the lift mechanism 15 with the upper side facing back will be explained.

When the operation button 23 is pressed, the swing frames 2a, 2b rise to the state shown in FIG. 12. Sewing machine 1
The tatami 16 on top of the tatami mat 16 is pushed by hand to move it onto the lift mechanism 15.

[Effects of the invention] One tatami mat weighs over 30 kg with straw flooring, and it would require a lot of labor if done by hand. However, according to the present invention, there is no need to manually lift the tatami floor, so it is possible to significantly prevent the consumption of human physical strength.

Additionally, compared to conventional fully automated systems, it requires less space and has a simpler structure, making it cheaper.
