Description

  The present invention relates to a folded cloth piece laminating apparatus. In laundry factories and the like, cloth pieces with a large area such as sheets are folded in small increments after washing, drying and pressing, and the folded cloth pieces are stacked in a predetermined number (for example, 7 to 10 pieces). And are shipped to hospitals. The present invention relates to a folding cloth piece laminating apparatus in which a predetermined number of such folding cloth pieces are laminated to form a laminated cloth piece.

  In order to stack the folded cloth pieces, sheets must be folded before that, but oversized sheets have a side length of up to about 3m and need to be folded several times. is there.

For example, in order to fold a large sheet as described above, the stretched cloth after pressing is folded into a zigzag shape with three parallel fold lines, folded into a quarter size, and then folded. Fold in half in the middle of the length and fold to the original size of 1/8, then fold in half in the middle of the length and fold to the original size of 1/16, and then in the middle of the length It is folded in half and folded to the original size of 1/32 to make a folded piece of cloth.
The final folded cloth pieces are sequentially stacked on the stacking conveyor one by one, and when stacked, for example, on the order of 7 to 10 sheets, are collectively transported to the next process (for example, a packing process).

As a conventional folding cloth piece laminating apparatus, there is a technique of Patent Document 1.
As shown in FIG. 10 and FIG. 11, the folded cloth piece laminating apparatus 140 includes a pair of gate plates 141, 141, an opening / closing device 142 that opens and closes both gate plates 141, 141, and both gate plates 141, 141. And a feeding conveyor 143 for feeding the folded cloth piece Y. A laminating conveyor 144 for laminating the folded folding cloth pieces Y is provided below the gate plates 141 and 141.

  The folded cloth piece laminating apparatus 140 is incorporated in a whole cloth folding machine that spreads and conveys sheets and the like. In this overall processing machine, sheets spread by a cloth spreader and pressed by a press machine are sequentially supplied from the discharge conveyor 161 on the press machine side onto the first end of the first conveyor 111 of the cloth folding apparatus 110. The The sheets supplied onto the starting end of the first conveyor 111 are successively reduced by the first to fifth folding sections 121 to 125 while being conveyed by the conveyors 111 to 119 of the cloth folding apparatus 110. The folded cloth piece Y is folded. Then, the folded cloth piece Y is conveyed to the folded cloth piece laminating apparatus 140 portion by the delivery device 130 and then fed to a predetermined position across the gate plates 141 and 141 by the feeding conveyor 143. Next, both gate plates 141 and 141 are opened, and the folded cloth piece Y falls to a fixed position on the laminated conveyor 144. Similarly, the subsequent folded cloth pieces Y sequentially fall from the gate plates 141 and 141, and a predetermined number (for example, 7 to 10) of folded cloth pieces Y are laminated on the laminated conveyor 144 to obtain a laminated cloth piece Z. . Then, the stacking conveyor 144 performs a discharging operation, and the stacked cloth pieces Z are further transferred to the table 146 via the discharging conveyor 145.

A basic structure of the laminating apparatus 140 will be described with reference to FIG.
The upper ends of the gate plates 141 and 141 arranged on the left and right are rotatably supported by pins 151. The cylinder 142 that is an opening / closing device and the pin 151 are connected via links 152 and 153. For this reason, when the cylinder 142 is expanded and contracted, the ends of the gate plates 141 can be opened and closed between a state in which the gate plate 141 hangs downward and a state in which the gate 142 is in horizontal horizontal orientation. When closing, the tip of each gate plate 141 rises from the bottom to the top and faces each other when it becomes horizontal. In this state, the folded cloth piece Y is placed across the gate plates 141 and 141, and then the gate plates 141 and 141 are opened.

As described above, when the two gate plates 141 are opened downward, the drop height h increases. That is, since the height corresponding to the width of the gate plate 141 must be opened on the stacking conveyor 144, the two gate plates 141 are positioned horizontally and are lower than the height when the folding cloth pieces Y are placed. The height to the stacking conveyor 144 must be higher than the width dimension of the gate plate 141.
When the folded cloth piece Y is dropped from such a high place, it is easy to cause inconveniences such as collapse of the folded shape or falling on the folded cloth that has been dropped first.

(First embodiment)
Based on FIGS. 1-3, the cloth piece laminating apparatus A of 1st Embodiment is demonstrated. In the following, the X direction shown in the figure is referred to as the left-right direction (or width direction), and the Y direction is referred to as the front-rear direction (or depth direction).

Reference numerals 1 and 1 denote stacker plates, which are provided with a pair of left and right plates. Each stacker plate 1, 1 is a rectangular plate-like member.
A front guide roller 2 is attached to the front and rear side surfaces of the front end of each stacker plate 1 (the end on the side where both stacker plates 1 and 1 face each other), and the base end of each stacker plate 1 (the one farther from the front end). The rear guide roller 3 is attached to the front and rear side surfaces at the end portion. The rear guide roller 3 includes a first roller 3a that guides in the left-right direction and a second roller 3b that guides in the front-rear direction within a vertical guide 6 to be described later.

5 is a horizontal guide, and 6 is a vertical guide. In either case, U-shaped steel or the like is used, and the inside is a U-groove.
The lateral guide 5 extends in the lateral direction, and two are disposed on the front and rear sides. The vertical guides 6 are fixed at both left and right end portions of the two horizontal guides 5 and are erected so as to individually extend in the vertical direction, and a total of four vertical guides are provided. Reference numeral 7 denotes a connecting beam that joins the upper ends of the four vertical guides.
The horizontal guide 5, the vertical guide 6, and the connecting beam 7 constitute a machine frame of the cloth stacking apparatus A. Therefore, it is not necessary to provide a separate frame material, and the machine frame has high rigidity.

  The front guide roller 2 is fitted in the U groove so as to roll in the horizontal guide 5, and the rear guide roller 3 is fitted in the U groove so as to roll in the vertical guide 6. The stacker plates 1 and 1 are movably supported. Further, since the rear guide roller 3 guides the left-right direction with the first roller 3a and the second roller 3b guides the front-rear direction, no blur occurs in any direction, front-rear, left-right, when the stacker plates 1, 1 are raised and lowered. Stable opening and closing operation is possible.

Reference numeral 10 denotes a push-pull drive unit that pushes and pulls the stacker plates 1 and 1.
The push / pull drive unit 10 includes a cylinder 11, a swing link 12 that changes the expansion / contraction operation of the cylinder 11 to a swing motion, and a lift link 13 that changes the swing motion to a lift operation of the stacker plate 1. The swing link 12 and the lift link 13 constitute a link mechanism as defined in the claims. The lower ends of the elevating links 13 are connected to the base end portions of the left and right stacker plates 1 and 1. The upper ends of the left and right lifting links 13 and the swing link 12 are connected by a shaft 14. For this reason, when one cylinder 11 expands and contracts, the base ends of the left and right stacker plates 1 and 1 are raised and lowered.

As shown in FIG. 1, when the cylinder 11 is contracted, the stacker plates 1 and 1 are closed in a horizontal state. That is, there is only a slight opening between the tip portions of the stacker plates 1 and 1, and the stacker plates are closed. As shown in FIG. 2, when the cylinder 11 is slightly extended, the swing link 12 is slightly tilted and the lift link 13 is moved, and the base end portions of the left and right stacker plates 1 and 1 are lifted and tilted. In this state, the tip portions of the left and right stacker plates 1 and 1 begin to open. The state shown in FIG. 3 is a state in which the cylinder 11 is extended and the proximal end portions of the stacker plates 1 and 1 are fully raised. At this time, the stacker plates 1 and 1 are almost vertical, and the opening between the tip portions is opened to the maximum. This state is an open body.
When the cylinder 11 is contracted from the state of FIG. 3, the base end portion of the stacker plates 1 and 1 descends as shown in FIG. 2, and finally the stacker plates 1 and 1 are horizontal as shown in FIG. And closed.

As described above, while the stacker plates 1 and 1 are opened and closed, the distal end portion moves laterally within the lateral guide 5 and the proximal end portion moves up and down within the longitudinal guide 6, but the guide rollers 2 and 3 are guided by the guide 5. , 6 rolls in the U-groove, so that the movement is smooth. In addition, the movement trajectory is always constant and no vibration occurs.
And since the height of the tip of the stacker plates 1 and 1 does not change at all, the height H between the stacking conveyor (reference numeral 4 in FIG. 6) to be disposed below can be made very low. .

Below, the usage method in the cloth lamination apparatus A of this embodiment is demonstrated.
As shown in FIG. 1, when the stacker plates 1 and 1 are closed, that is, the stacker plates 1 and 1 are horizontal and the space between the tips is narrowed, the folded cloth piece Y is drawn. Make it. The folding cloth piece Y may be pulled in by an appropriate conveyor. Next, the left and right stacker plates 1 and 1 are opened, and when the opening between the tips widens as shown in FIG. 3, the folded cloth piece Y falls downward.

In the above embodiment, the stacking conveyor disposed below the stacker plates 1 and 1 is not shown. However, if the stacking conveyor 4 as illustrated in FIGS. 6 and 9 is disposed, the folded cloth piece Y is placed thereon. Thus, the folded cloth pieces Y can be sequentially stacked and further conveyed to the next process.
In the first embodiment, the pressing device for the folding cloth piece Y is not shown, but in order to prevent the folding cloth piece Y from being deformed when dropped, it is preferable to provide an appropriate pressing device.
Next, an embodiment provided with a presser device will be described.

(Second Embodiment)
The basic configuration of the second embodiment of FIGS. 4 to 6 is the same as that of the first embodiment of FIGS. 1 to 3, and is provided with a roller-type pressing device 20. In addition, the same code | symbol is attached | subjected to the part same as 1st Embodiment, and description is abbreviate | omitted.

The presser device 20 has two arms 22 each having a roller 21, and the arms 22 are attached to a support body 23.
The two arms 22 are biased by a biasing means such as a spring, and each roller 21 presses the folded cloth piece Y on the stacker plates 1 and 1 lightly.

  In addition, as shown in FIG. 6, the lamination | stacking conveyor 4 is arrange | positioned under both the stacker plates 1 and 1. As shown in FIG. The laminated conveyor 4 can be constituted by a known conveyor in which a belt is wound endlessly between two rollers.

Next, the stacking operation of the folding cloth pieces Y according to the second embodiment will be described.
In the state where the stacker plates 1 and 1 shown in FIG. 4 are horizontal, the folded cloth piece Y is fed into the stacker plates 1 and 1. The folded cloth piece Y is placed on both the stacker plates 1 and 1 across the left and right stacker plates 1 and 1.
Thereafter, the upper surface of the folded cloth Y is lightly pressed by the roller 21 of the pressing device.

Next, as shown in FIG. 5, when the cylinder 11 is extended and the base ends of both stacker plates 1 and 1 are raised, the tip ends of both stacker plates 1 and 1 are opened to the left and right as a whole. Increasing the slope.
At this time, since the roller 21 of the presser device 20 presses the upper surface of the folded cloth piece Y while rotating, the folded shape of the folded cloth piece Y does not collapse.

  As shown in FIG. 6, when both the stacker plates 1 and 1 are in an upright state, a large opening is formed between the tip portions of the both stacker plates 1 and 1, so that the folded cloth piece Y falls from between them. The fallen folded cloth piece Y is placed on the lower layered conveyor 4 and laminated on the folded cloth piece Y previously placed. When this operation is repeated several times (for example, 7 to 10 times), the laminated cloth piece Z is obtained.

  In the present embodiment, since the tips of the stacker plates 1 and 1 do not move up and down, the height H between the stacking conveyors 4 arranged below the stacker plates 1 and 1 may be considerably small. For this reason, the fall position of a folding cloth piece does not shift, or a folding state does not collapse.

(Third embodiment)
Next, a third embodiment will be described with reference to FIGS.
Since the basic structure of this embodiment is the same as that of the first embodiment, the same parts are denoted by the same reference numerals and description thereof is omitted.

A cotton belt is used as the presser device 30.
Reference numeral 31 is a cotton belt, which is wound endlessly between two pulleys (not shown) in the same manner as a known belt conveyor. An intermediate portion between the two pulleys in the cotton belt 31 comes into contact with the upper surface of the stacker plate 1.

The stacking operation of the folding cloth pieces Y according to the third embodiment will be described below.
In the state where the stacker plates 1 and 1 shown in FIG. 7 are horizontal, the folded cloth piece Y is placed thereon, and the cotton belt 31 is lightly pressed on the upper surface thereof.
As shown in FIG. 8, when the stacker plates 1 and 1 are inclined, the cotton belt 31 presses the folded cloth piece Y, so that the shape of the folded cloth piece Y does not collapse. As shown in FIG. 9, when the stacker plates 1 and 1 are opened, the folded cloth pieces Y drop onto the lower laminated conveyor 4 from the opening therebetween and are stacked on the laminated cloth pieces Z.

  Also in the third embodiment, since the tips of the stacker plates 1 and 1 do not move up and down, the height H between the stacked conveyors 4 arranged below the stacker plates 1 and 1 may be considerably small. For this reason, the fall position of a folding cloth piece does not shift, or a folding state does not collapse.

  In each embodiment of the present invention, the base end portion of the stacker plates 1 and 1 is moved up and down by the vertical guide 6, but the front end portion is moved horizontally by the horizontal guide 5, so that the overall height of the opening and closing operation is increased. I don't need it. Therefore, since the height between the stacker plates 1 and 1 and the conveyor disposed below the lower is lowered, the falling distance of the folded cloth piece Y is shortened, the falling position of the folded cloth piece Y is shifted, or the folded state is changed. There is no collapse.

  Further, the expansion and contraction operation of the cylinder 11 converts the left and right stacker plates 1 and 1 to open and close in the horizontal direction, so that the opening and closing operation can be reliably performed with a simple structure, and the movement path of the stacker plates 1 and 1 Since the drive unit can be kept away from the moving path of the folding cloth piece Y, no external force is applied to the taking-in operation and the dropping action of the folding cloth piece Y.

  Furthermore, since two of the horizontal guides 5 and four of the vertical guides 6 are connected by the connecting beam 7 to form a strong machine frame, there is no need to provide a separate frame, and the push-pull drive unit 10 is connected to the connecting beam 7. By attaching, the space | interval which keeps away from the stacker board 1 and 1 and draws in the folding cloth piece to the stacker board 1 and 1 and temporarily hold | suppresses the folding cloth piece at the time of dropping, etc. can be ensured.
