Stacking apparatus
A stacking apparatus includes a conveyance unit, a stacking unit, and a separation member supply unit. The conveyance unit conveys sheets for circuit board. The stacking unit stacks the sheets. The separation member supply unit supplies a separation member to separate the stacked sheets at any position. The separation member supply unit places the separation member on the sheet in being conveyed.
1. A stacking apparatus, comprising:
a conveyance unit that conveys circuit board sheets;
a stacking unit that stacks the circuit board sheets; and
a separation member supply unit that is disposed above the conveyance unit on an upstream side of the stacking unit in a conveyance direction, the separation member supply unit supplying a separation member to separate the stacked circuit board sheets at any position, wherein
the separation member supply unit supplies the separation member obliquely downward toward a circuit board sheet being conveyed by the conveyance unit in the conveyance direction and places the separation member on the circuit board sheet.
2. The stacking apparatus according to claim 1 , wherein the separation member supply unit supplies the separation member before the circuit board sheet is stacked on the stacking unit.
3. The stacking apparatus according to claim 2 , wherein the separation member supply unit supplies the separation member at the same speed as a speed of the circuit board sheet in being conveyed.
4. The stacking apparatus according to claim 1 , wherein the separation member supply unit supplies the separation member at the same speed as a speed of the circuit board sheet being conveyed.
5. The stacking apparatus according to claim 1 , wherein the separation member differs from the circuit board sheet in at least one of a thickness, a size, a color, or a material.
6. The stacking apparatus according to claim 1 , wherein the separation member has a color different from a color of the circuit board sheet.
7. The stacking apparatus according to claim 1 , wherein the separation member is made of the same material as a material of the circuit board sheet.
8. The stacking apparatus according to claim 1 , wherein at least one width of the separation member is equal to at least one width of the circuit board sheet.
9. The stacking apparatus according to claim 1 , wherein the separation member has a thickness smaller than a thickness of the circuit board sheet.
10. The stacking apparatus according to claim 1 , wherein the separation member is dust-free paper.
11. The stacking apparatus according to claim 1 , wherein the separation member supply unit includes a forming section that forms a crease on the separation member.
12. The stacking apparatus according to claim 11 , wherein a direction of the crease coincides with a direction in which the separation member is supplied on the circuit board sheet.
13. The stacking apparatus according to claim 11 , wherein the forming section forms a plurality of creases in parallel with one another on the separation member.
14. The stacking apparatus according to claim 1 , wherein the separation member supply unit is disposed on an upstream side of the stacking unit in a conveyance direction of the circuit board sheet.
15. The stacking apparatus according to claim 1 , wherein the circuit board sheet has lower wear resistance than the separation member.
16. The stacking apparatus according to claim 1 , wherein the circuit board sheet is a prepreg material.
