Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a dry ice cutting device for cutting dry ice.

[0002]

2. Description of the Related Art A conventional dry ice cutting device has a table having a band saw insertion portion at a substantially central portion, which is mounted on a machine frame so as to be slidable in the front-rear direction, and slides the dry ice forward on the table. The band saw is attached to the machine frame so that the dry ice can be cut by moving the dry ice.

[0003]

In the conventional dry ice cutting device, the table slides forward and backward,
If a person accidentally puts his / her hand on the table, there is a risk of cutting his / her hand with a band saw. In addition, there is a drawback that the band saw is exposed on the table, which is dangerous and that the band saw is easily damaged when a baggage of another worker collides with the side surface of the band saw.

In view of the above-mentioned conventional drawbacks, the present invention has been made.
If you do not need to move the table, you can lock the movement of the table to prevent danger, and you can determine whether the table is locked or unlocked at a glance, and the band saw can be exposed when not in use. An object of the present invention is to provide a dry ice cutting device capable of surely preventing damage to a band saw and preventing danger.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in view of the accompanying drawings. However, the drawings are only for explanation and do not limit the technical scope of the present invention.

[0006]

In order to achieve the above object, the present invention is a table having a band saw insertion portion at a substantially central portion, which is attached to a table support of a machine frame so as to be slidable in the front-rear direction. By placing dry ice on this table and sliding it forward, a band saw attached to the machine frame so that the dry ice can be cut, and one side portion of the table are projected outward. A support piece having a pin insertion hole fixed to the pin, and a pin fixed to a machine frame or a table support part that supports the table at a position where the support piece is located, with the table located at the front part A fixed piece having an insertion hole, and the support piece suspended from the fixed piece or a machine frame or table support near the fixed piece via a string member such as a chain. Insert detachably on the pin insertion hole of the pin insertion hole and the fixing piece, constitute the dry ice cutting device with a locking piece for locking the movement of the table.
