Thus, in this invention, since the temperature rise of the workpiece | work is suppressed before returning to a blade edge table, the temperature rise of the workpiece | work at the time of a cutting | disconnection can be suppressed reliably, and favorable cutting can be performed.

<Embodiment 1>
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 to 10. The slicer according to the present embodiment includes a cutting table 10, a blade edge table 12, and a pressing member 18. A workpiece (not shown) is pressed from above by the pressing member 18, placed on the upper surfaces of the blade table 12 and the cutting table 10, and in the process of sliding from the blade table 12 to the cutting table 10, Is cut into thin slices by the cutting blade 11.

  The cutting table 10 is made of metal and is supported horizontally. An edge on the upstream side in the workpiece conveyance direction (right side in FIGS. 2 and 6) at the time of cutting in the cutting table 10 is inclined with respect to the conveyance direction. A cutting blade 11 is attached. The blade edge table 12 is made of metal and is supported horizontally and at substantially the same height as the cutting table 10. The blade edge table 12 is disposed on the upstream side of the cutting table 10 in the workpiece conveyance direction at the time of cutting, and the edge on the downstream side of the workpiece conveyance direction at the time of cutting in the blade edge table 12 is oblique to the conveyance direction (cutting). A long and narrow metal blade 13 is attached to the oblique downstream end edge of the table 10.

  On the downstream side of the cutting table 10, a plurality of transport rollers 14 whose axes are oriented perpendicular to the transport direction, and an auxiliary table 15 made of metal elongated in a direction perpendicular to the transport direction provided between adjacent transport rollers 14. The downstream side conveyance path 16 comprised from these is provided. Further, on the upstream side of the blade table 12, a plurality of transport rollers 14 whose axes are oriented perpendicular to the transport direction and a metal that is elongated in a direction perpendicular to the transport direction provided between the adjacent transport rollers 14 are provided. An upstream conveyance path 17 composed of the auxiliary table 15 is provided.

  The pressing member 18 is a member in which an endless pressing belt 20 is wound between a pair of driving rollers 19 whose axis is directed at right angles to the conveying direction, and the driving roller 19 is interposed between the pair of driving rollers 19. And a plurality of pressing rollers 21 that are in contact with the upper surface of the horizontal running portion on the lower side of the pressing belt 20 are arranged. When the drive roller 19 is driven to rotate, the pressing belt 20 rotates in one direction, and the workpiece is caused to be conveyed by the friction between the lower surface of the pressing belt 20 and the upper surface of the workpiece, the upstream conveying path 17, the blade edge table 12, the cutting. It is conveyed in the order of the table 10 and the downstream conveyance path 16. When the workpiece is transferred from the blade edge table 12 to the cutting table 10, the lower surface is cut thinly by the cutting blade 11.

  When the cut workpiece reaches the downstream conveyance path 16, the driving direction of the driving roller 19 of the pressing member 18 is switched from normal rotation to reverse rotation, and the workpiece passes through the cutting table 10 and the blade edge table 12 in order. And returned to the upstream conveyance path 17. Thereafter, the drive roller 19 is switched to forward rotation, and the workpiece is cut again. As described above, in this embodiment, the workpiece is repeatedly cut by reciprocating the workpiece across the cutting blade 11.

  In this embodiment, the workpiece is pressed against the upper surface of the conveyance path constituted by the upstream conveyance path 17, the blade table 12, the cutting table 10, and the downstream conveyance path 16 by the pressing member 18. Heat is generated by friction with the lower surface of the workpiece. For this reason, when the workpiece is a heat-softening synthetic resin such as polyvinyl chloride or urethane resin, the temperature of the lower surface of the workpiece rises due to the transmission of frictional heat generated in the conveyance path. There is a concern that cutting will not be performed.

Therefore, in this embodiment, cooling means for suppressing the frictional heat generated in the conveyance path from being transmitted to the workpiece is provided in the cutting blade 11, the cutting table 10, the blade edge table 12, and the auxiliary table 15. ing.

A supply path (not shown) such as a hose is connected to one open end of the flow path 23, and a discharge path (not shown) such as a hose is connected to the other open end. Further, the cutting table 10 is formed with a circular cross-section channel 24 that branches off from the upstream channel of the pair of channels 23 and opens at the upstream edge of the cutting table 10. A supply path or a discharge path (not shown) such as a hose is connected to the opening at the upstream end of the flow path 24.

  As shown in FIGS. 7 and 8, a pair of hole-shaped flow paths 25 extending perpendicularly to the workpiece transfer direction are formed inside the blade table 12. The flow path 25 has a form penetrating the blade table 12, and the cross-sectional shape perpendicular to the penetrating direction is circular (see FIG. 7). A supply path (not shown) such as a hose is connected to one open end of the flow path 25, and a discharge path (not shown) such as a hose is connected to the other open end. The blade table 12 is formed with a circular cross-sectional flow channel 26 that branches from the flow channel 25 located on the downstream side of the pair of flow channels 25 and opens to the downstream edge of the blade table 12. Yes. A supply path or a discharge path (not shown) such as a hose is connected to the opening at the downstream end of the flow path 26.

Immediately before and during cutting of the workpiece, cooling water (fluid which is a constituent feature of the present invention) flows through each of the flow paths 22, 23, 24, 25, 26 and 27. By flowing the cooling water, the frictional heat generated in the cutting blade 11, the cutting table 10, the blade edge table 12, and the auxiliary table 15 is all taken away by the cooling water, so that it is hardly transmitted to the workpiece. The lower surface of the workpiece is kept at a relatively low temperature. Therefore, the cutting defect resulting from the temperature rise of the lower surface of the workpiece is avoided.

In the present embodiment, the coolant and the workpiece can be set at a temperature suitable for cutting the workpiece by circulating the cooling water through the flow path 22 formed in the cutter blade 11. 11 can be prevented from being cut due to the heat transfer between the two.
