Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a stacking device for sewing materials such as fabrics.

(Prior art and its problems) In factories that make suits and other garments, the sewing materials, which are cut into predetermined dimensions, are fed in order and processed, but the sewing materials that are fed in order are once stacked at the joints of the process. It may be necessary to stock up. In this case, so that so-called first-in, first-out is possible, the items sent in first are placed on top.
It is necessary to stack the items that come later on the bottom in order, but there is no stacking device that can stack sheet materials such as pieces of cloth for sewing on the bottom in this way.

(Technical means for solving the problem) An object of the present invention is to provide a stacking device capable of stacking sheet materials such as the above-mentioned pieces of cloth for sewing downward one after another. A plurality of arms are arranged horizontally in a comb-like manner at intervals from each other, and a fixed-position pallet is supported at a fixed position, and a plurality of arms pass vertically through the space between the arms of the fixed-position pallet. A movable pallet arranged horizontally in a comb-like manner and supported so as to be movable back and forth between a position vertically overlapping with the fixed position pallet and a position away from the fixed position pallet, and a movable pallet in which the movable pallet is in a retracted position. From the initial state, the moving pallet is superimposed on the fixed-position pallet, and then the levels of the fixed-position pallet and the moving pallet are almost the same, and then the moving pallet is moved backward, and then the moving pallet is moved forward until it reaches the fixed position. The gist of the system is a stacking device equipped with a pallet operating device that moves the movable panel up and down so that it is positioned above the fixed-position pallet after stacking it on the bottom of the pallet, and then returns the movable panel to its initial state. .

(Embodiment) Below, an embodiment of the present invention will be described. FIG. 1 is a plan view showing one example of a stacking device according to the present invention. Two pallets 2 and 3 arranged in parallel are provided on a base 4. One pallet 2 is a fixed position pallet that moves up and down in a fixed position, and the other pallet is a moving pallet that moves horizontally back and forth between a position overlapping the fixed position pallet 2 vertically and a position away from the fixed position pallet 2. be.

The fixed position pallet 2 has a horizontally supported base frame 5.
The bases of the arms 6, 6, . A movable frame 11 equipped with rollers 10 in contact with the rail is attached to the vertical rails 9, which also serve as legs of the base 4, so as to be movable up and down.
is fixed. At the center of the moving frame 11, a cylinder tube 13 is attached to a horizontal bar provided on the moving frame 11.
The upper end of a is attached and the piston rod 13
An air cylinder 13 attached to the floor F is provided at the tip of b. This air cylinder 13
By expanding and contracting, the fixed position pallet 2 fixed to the moving frame moves up and down. Note that the upper surface of the base 4 has a recess 1 into which the arms 6, 6, ... are fitted.
2, 12, . . An anti-slip 6a is attached to the upper surface of the arm 6.

The movable pallet 3 is arranged in a space between the arms 6, 6, . . . of the fixed position pallet 2, and has arms 15, 15, . The outer surface of the arm 15 is coated with Teflon to reduce friction. Base frame 1
7 are two elongated holes 19, 19 bored in the base 4.
It is supported by columns 20, 20 passing through it vertically, and the lower end of this column 20 is attached to a moving frame 25 equipped with a roller 23 that rotates in contact with a horizontal rail 21 provided at the bottom of the base. Fixed. A piston rod 27b tip of an air cylinder 27 is attached to the moving frame 25, and the end of the cylinder tube 27a is attached to the fixed frame 29 of the base 4. By expanding and contracting the air cylinder 27, The movable pallet 3 fixed to the movable frame 25 can be moved back and forth along the elongated hole 19.

The air cylinders 13 and 2 are located below the base 4.
A control box 30 containing a built-in valve for switching and supplying air to air pump 7 is installed. In the figure,
31 is a limit switch for detecting the vertical position of the fixed position pallet 2;

This stacking device 1 is installed at the terminal end of a conveyor 35 that conveys workpieces such as sewing materials from a previous process. At the end of the conveyor 35, a feeding device 39 equipped with a presser 37 whose lower end is made of sponge, and a photoelectric sensor 40 for detecting when the work has reached the end of the conveyor 35 are installed. ing. The presser 37 is attached to the tip of the piston rod 41b of the air cylinder 41, and the cylinder tube 41a of the air cylinder 41 is attached to a hook-shaped support 43. Support 4
3 is supported while being slidably fitted into a guide groove 47 of a guide tool 45 provided along the base 4, and drive pulleys 4 provided at both ends of the guide tool 45.
9, 49' and the belt 50 hooked thereon, it is caused to reciprocate along the guide groove 47.

Next, to explain the operation of this stacking device, when the work W is carried to the end of the conveyance by the conveyor 35, the sensor 40 detects this and extends the air cylinder 41, and the presser 37
, lower it. When the presser 37 presses down the workpiece W, the drive pulleys 49, 49' rotate and move the presser 37 in the direction of the arrow X, so that the workpiece W is held down.
is placed on the pallet 2 by sliding on the upper surface of the arm 6 of the fixed position pallet 2 in the lowest position.
After feeding the work W to the deep end, press the presser 37.
rises and returns to its original position.

Note that even if the sensor 40 detects the workpiece W, if the stacking device 1 is in operation, the feeding device 39
is not activated and the conveyor 35 is stopped. That is, the feeding device 39 is configured such that the workpiece W exists at the end of the conveyor and the stacking device 1
It operates only when is in the initial state, and the work W
on the pallet.

The workpiece W is fed onto the fixed position pallet 2,
When the photoelectric sensor 55 detects this, the moving pallet 3, which was in the retreat position, moves forward to a position where it overlaps the fixed position pallet 2 (Fig. 4 a), and the fixed position pallet 2 moves up one step (Fig. 4 b). ) It will be at almost the same level as moving pallet 3 (c in the same figure). In this state, the arm 15 of the movable pallet 3 enters the space between the arms 6 of the fixed-position pallet 2, and the lower surface of the lowest part of the preceding workpieces stacked on the movable pallet 3 is placed on the fixed-position pallet 2. It comes into contact with the upper surface of a new workpiece placed on it. When the moving pallet 3 retreats from this state, the moving pallet 3
The arm 15 of the moving pallet 3 is slippery.
The upper work is placed on the work on the fixed position pallet 2 and remains there (d in the figure). Next, the fixed-position pallet 2 rises one step further and becomes higher than the level of the moving pallet 3 (see e in the figure), and the moving pallet 3 moves forward and overlaps the lower side of the fixed-position pallet 2. (Figure f). From this state, when the fixed position pallet descends to the initial position (lowest stage) below the moving pallet 3, the workpieces loaded on the fixed position pallet 2 are transferred onto the warp moving pallet 3 ( Figure g. At this time, the newly fed workpiece is stacked on the lowest stage.Then, the movable pallet 3 retreats and the stacking device 1 returns to its initial state. Subsequent workpieces are always stacked on the bottom, and the order of the workpieces is never messed up.

In this embodiment, only the fixed position pallet 2 is moved up and down, but the movable pallet 3 may be moved up and down with respect to the fixed position pallet. Alternatively, the moving pallet 3 may be placed on the side of the fixed position pallet 2 in the figure, the fixed position pallet 2 may be placed at the position of the moving pallet 3 in the figure, and the workpieces may be piled up on the fixed position pallet.

(Effects of the Invention) As is clear from the above description, the sheet material stacking device according to the present invention is excellent in that it can sequentially stack sheet materials such as sewing materials downward.
