JPS6024557Y2 - Tatami face gripping device in tatami face fixed length cutting machine - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a tatami facing gripping device in a tatami facing fixed length cutting machine.

This invention is based on a patent application filed in 1975, in which a long woven tatami mat is first cut into various specified dimensions such as Kyo-ma, Naka-kyo-ma, and Hyo-ga, and then pulled out horizontally to form a stacked state for convenient handling.
No. 5-140774 was proposed.

The present invention prevents errors during cutting by effectively holding the cut edges of the tatami mat in the fixed length cutting machine for tatami mat and preventing slippage during the removal of the tatami mat. Moreover, it allows accurate cutting to be performed according to specified dimensions.

An example of implementing the present invention will be described below with reference to the drawings.

FIG. 1 is an overall perspective view of a tatami mat length cutting machine using the device of the present invention, in which a pair of horizontal beams F and F' are provided in parallel at a constant height position, and the boom A tatami mat feeding device A is configured in the front half of the tatami mat cover, and a pulling means B for picking up the tatami mat cover to a fixed length is configured in the rear half of the tatami mat cover.
Further, a cutting means C is interposed between the two means.

The holding device of the present invention relates to the above-mentioned taking-off means B, and the details of this construction are as shown in FIG.

Reference numeral 1 denotes a concave bracket that bridges between the horizontal beams F and F', and is guided by guide rails provided on each horizontal beam and is made to travel by an appropriate drive means, and the central inside of the bracket has air cylinder 2
is installed horizontally.

3 is a central projecting plate provided in the same horizontal direction as the cylinder 2 at the cylinder position,
A bearing 4 is provided at a certain distance forward position on the plate surface, and a lever 7 which is connected to the tip of the piston rod 5 of the cylinder via a pin 6 is pivotally supported on the bearing 4. .

In this case, the lever 7 is integrally attached to the rotating shaft of the holding plate, which will be described below.

Note that 8a and 8b are wing plates provided at both left and right axial positions, and bearings 9a and 9b are provided on the plate surfaces to support both ends of the rotating shaft of the presser plate.

Reference numeral 10.10' denotes a presser plate having an inverted V-shaped cross section, which extends from the rotating shaft 11 to the arms 12a, 12b, 12'a.
, 12'b, and when the lever 7 is swung back and forth in the directions A and B by the movement of the piston rod 5 of the cylinder 2, the levers 7 and 7 are integrally attached via the rotary shaft 11 in the up and down directions. It is made to sway.

Reference numeral 13 denotes a receiving plate, which is attached to a lower surface position opposite to the holding plate 10, 10' via wing plates 8a and 8b, respectively.

In this case, the width dimension 1 of the receiving plate is a chevron-shaped holding plate 10.
10', and the front and rear corners p and p' of the receiving plate come into contact with the ceiling inner wall surfaces S and S' of the holding plates 10 and 10', which have an inverted V-shaped cross section. ing.

(See Fig. 3) The present invention is constructed as described above, and the tatami mat 14 is placed on the receiving plate 1 with the piston rod 5 of the cylinder 2 being pulled and the holding plates 10, 10' being lifted upwards.
In this state, the piston rod 5 advances and the holding plates 10 and 10' are pushed down, so that the tatami mat cover 14 is sandwiched between it and the receiving plate 13.

(See Figure 4) As seen in the drawing, the present invention
4 is held between the corners p and p' on the receiving plate 13 and the inner wall surfaces S and S' of the ceiling, which have an inverted cross-section, and the tatami surface is folded in at these parts. Since it is gripped in a wave-like shape as a whole, slippage is completely prevented and errors during cutting are prevented, making it possible to pick up and cut accurately according to specified dimensions.
