Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a food slicer that cuts food with a rotating round knife, and when a device that locks a knife cover that covers the cutting edge of the round knife in its attached state is released, the food slicer Relating to a safety device that prohibits the driving of

In a food slicer, a feeding box that stores food such as meat chunks is reciprocated toward a rotating round knife, and the food is sequentially sliced with the round knife. A blade cover covering the round blade is removably provided, and when replacing or cleaning the round blade, the blade cover is removed to expose the cutting edge of the round blade on the opposite side to the cutting side. However, when the cutting edge of the round knife is exposed, the operation switch of the food slicer may be operated by mistake. In such a case, the conventional food slicer is started by operating the operation switch, the round cutter begins to rotate, and the feeding box begins to reciprocate. This is extremely dangerous and may cause injury.

It is an object of the present invention to provide a food slicer knife cover safety device that eliminates the above-mentioned conventional drawbacks.

The present invention provides a food slicer that reciprocates a feeding box for storing food toward a rotating round knife and sequentially cuts the food with the round knife, and the present invention provides a knife that covers the cutting edge of the round knife on the opposite side to the cutting side. A food product characterized by C, wherein the cover is removably attached, a device is provided for locking the cutter cover in the attached state, and a switch for prohibiting driving of the food slicer is provided so as to be operable by releasing the locking device of the cutter cover. This is a safety device for the slicer blade cover.

In this safety device, when the locking device of the cutter cover is released, a switch that prohibits driving of the food slicer is activated, and driving of the food slicer is prohibited. Therefore, even if the food slicer's operation switch is operated by mistake when the locking device of the cutter cover is released and the cutter cover is removed, the food slicer will not operate.
It is safe because there is no chance of the worker being injured by a round knife or the like that suddenly starts moving.

Next, examples of the present invention will be described.

As shown in Figs. 1 and 2, the food 7 cooker equipped with the safety device for the cutter cover of this example has a cutter rest (2) installed on the negative side of the machine stand (1), and ) is attached to the upper end of the rotating shaft (3
) is pivotally supported, a circular disc-shaped round cutter (4) is attached to the tip of the rotating shaft (3), and the end of the rotating shaft (3) is connected to a brake motor (7) via a belt transmission mechanism (6). In addition, the feeding box (8) is mounted on the machine base (1) so as to be able to slide in two directions, and the feeding box (8) is connected to the machine via a crank mechanism (not shown). The feeding box (8) is connected to a motor with a brake (not shown) so as to reciprocate toward the round cutter (4). As shown in Fig. 1, a device (9) is provided for polishing the upper cutting edge of the round knife (4) with a whetstone.On the side of the tool rest (2), as shown in Figs. platen) (
