Description

[Detailed description of the invention] This invention relates to a sheet material stacking device,
More specifically, the present invention relates to a stacking device that automatically folds and stacks sheet-like flexible materials into a predetermined state.

Conventionally, when this type of device folds and stacks flexible sheet materials such as rubber sheets, the stacking is done only by the swinging motion of a pendulum-shaped feeding device that swings and guides the supplied sheet material. As a result, as shown in FIG. 1a, both ends of the sheet material W become disordered and uneven, and it is therefore necessary to manually correct the stacking so that it can be stacked properly.

Various devices have been proposed in the past in order to solve the problem of manually correcting the stacking so that it stacks up properly. It consists of a guide device that periodically changes the amplitude of the member, a detection device that detects the height of the top surface of the stacked sheet materials, and a lifting device that lowers in conjunction with this detection device. A stacking method is disclosed in which both ends of sheet materials are periodically shifted.

However, in the case of such a conventional device, although it is suitable for rubber sheet materials with a thickness of several millimeters or more and is highly elastic, it is difficult to adjust the folding position when stacking highly elastic sheet materials of a thickness of several millimeters or less in multiple stages. As shown in FIG. 1b, although the folding position is changed periodically, there is a problem in that the folding position is concentrated at both ends, causing the load to collapse.

This invention was devised by focusing on the conventional problems, and its purpose is to automatically stabilize the sheet material by periodically shifting the folded ends of the sheet material and changing the alignment width. This sheet eliminates the need to manually correct the folded parts of the sheet materials so that they can be stacked in a normal state, and can efficiently stack highly elastic sheet materials with a thickness of several millimeters or less. The present invention provides a material stacking device.

In order to achieve the above object, the present invention includes a swinging feeding device that guides and supplies the supplied sheet material at a constant amplitude, and a sheet receiving carriage that is reciprocatably disposed below the swinging feeding device. and a control device for controlling the movement of the swinging supply device and the sheet receiving carriage, and the control device controls the left and right reciprocating speed of the sheet receiving carriage and the swinging speed of the swinging feeding device. The gist of the present invention is to periodically shift both folded ends of the sheet material by controlling relative displacement, and to automatically change the width of the sheet material so that the sheet material is stacked in multiple stages.

Embodiments of the present invention will be described below with reference to FIGS. 2 and 3 a and b of the accompanying drawings. FIG. 2 shows a schematic configuration diagram of a stacking device according to the present invention. 10, and a control device 100 that controls the reciprocating movement of the sheet receiving carriage 50.

The swing supply device 10 includes a conveyor 11 that conveys the sheet material W from the previous process, and a drive motor 14 that rotationally drives the conveyor 11 via sprockets 12a, 12b and a chain 13.
The sprocket 12 is attached to this drive motor 14.
b, a chain 15, a sprocket 16, and a swing supply mechanism 18 for sheet material W connected via a crank mechanism 17.

The crank mechanism 17 is composed of a crank arm 20 connected coaxially with the sprocket 16 and a link 22 rotatably connected to the crank arm 20 via a pin 21. , a swinging supply mechanism 1 for sheet material W that is swingably installed vertically around a pin 23 as a fulcrum.
The central portions of the swing arms 24 at 8 are connected via pins 25.

Therefore, when the drive motor 14 rotates, the sprocket 12b→chain 15→sprocket 1
6→The crank arm 20 rotates in a predetermined direction via the shaft 19, and at the same time, the pin 2 is attached to the link 22.

The sheet materials W are piled up with a predetermined width on the sheet receiving carriage 50 while swinging in the direction of the arrow with the fulcrum being the fulcrum.

Next, the sheet receiving carriage 50 is moved to the frame 5.

02 is installed. This gear box 10
A gear mechanism (not shown) in 2 meshes with a spline shaft 104 installed on the frame 51 via a support plate 103. Further, at both ends of the pedestal 54, there are provided proximity pieces 107 which can come into contact with a proximity switch 106 via adjustable rods 105, and the proximity switch 106 is electrically connected to the control device 100. .

Proximity piece 1 provided via the rod 105
07 and the proximity switch 106 are for regulating the left and right movement range of the sheet receiving carriage 50, and this control is controlled by the variable speed motor 101 via the control device 100.
By rotating forward or backward, the sheet receiving carriage 50 is moved within a predetermined range along the spline shaft 104 via a gear mechanism (not shown) in the gearbox 102, and both folded ends of the sheet material W are moved. By periodically shifting the section W as shown in FIGS. 3a and 3b and changing the arrangement width L, the sheet materials W are automatically and stably stacked. That is, the control to periodically shift the folded ends W of the sheet material W is made possible by relatively shifting the left and right reciprocating speed of the sheet receiving carriage 50 and the swinging speed of the swinging supply mechanism 18. The control device 100
It is going by.

Both folded ends of the sheet material are controlled to shift periodically, and the width of the sheet material is automatically changed to stack the sheet materials in multiple stages. By shifting the target and changing the arrangement width, it is possible to automatically stack up in a stable state, and especially highly elastic sheet materials with a thickness of several millimeters or less can be stacked efficiently.

Moreover, since the structure is simple, it can be manufactured at low cost and maintenance is also easy.
