Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a baking sheet oil applicator for manufacturing confectionery, cakes, bread, etc.

Conventionally, in the production of confectionery, cakes, bread, etc., dough is placed on a baking sheet and baked in an oven, and when the baked bread, etc. is removed from the baking sheet, the baking sheet and the bread stick together due to the heat, causing problems. There were many cases where it could not be removed. Therefore, an oil called mold release oil was applied to make it easier to take out the mold. However, although this application of mold release oil was performed manually with a brush or the like, it has been mechanized because it is extremely inefficient. Due to this mechanization,
A spray gun for paint, etc. is used, and the spray gun is either manually installed or attached to a fixed device above the top plate to inject oil. A detection device detects the plate, activates an oil pumping device, and sprays oil using a spray gun to coat the top plate. However, the top plate is recessed with mold holes to accommodate multiple rows of bread dough, and the purpose of applying oil is to coat the inside of these mold holes, and applying oil to areas other than the mold holes is a waste of oil. The position, number, and depth of the mold holes vary depending on the shape of the product, so the nozzle position must be corrected each time the top plate is changed, and the nozzle position must be adjusted to match the mold hole of the top plate. It is necessary to provide as many nozzles as possible, and furthermore, since the oil is applied by a spray gun, the oil becomes a mist and flies around, creating an environment that is not favorable for health.

The present invention has been made in view of the above-mentioned conventional drawbacks, and provides a top plate oil applicator that can prevent oil from scattering and can evenly apply oil to the inside of mold holes in various types of mold holes. The purpose is to provide a top plate push-up device that pushes the top plate upwards on the way of the top plate conveyor, and an opening that opens downward above the top plate push-up device. and a masking plate having holes aligned with a plurality of mold holes recessed in the top plate is removably attached to the opening side of the injection box to prevent the opening from being openable and closable. An ejection chamber consisting of a movable lid is provided, and a movable pedestal on which a plurality of nozzle units are arranged side by side is disposed on the upper side of the ejection chamber so as to be movable back and forth, so that the tips of the nozzles of the nozzle units are connected to the ejection chamber.

Therefore, when applying oil to the mold hole Wa, oil is applied to the bottom surface and the circular edge of the mold hole Wa on the rear side in the conveyance direction of the top plate W during the forward movement, and to the circular edge surface which is the rear side of the mold hole Wa in the conveyance direction of the top plate W, and during the backward movement. The inner surface of the mold hole Wa can be uniformly coated by coating the bottom surface and the circular edge surface which are the front side of the hole Wa.
In particular, when coating a vertical circular edge surface, by tilting the nozzle unit 82 back and forth during its movement process, uniform coating can be achieved regardless of the size and depth of the mold hole Wa. Further, since the nozzle unit 82 is arranged on the movable frame 73 and moves back and forth, the number can be reduced to the minimum required number. Further, since the oil is injected into the injection chamber C, the oil does not become a mist and scatter around, thereby improving environmental hygiene. In addition, this example device has the top plate conveying section A, the top pushing device B, the injection chamber, and the injection device D arranged in a hierarchical manner, so it can be configured compactly and the installation area can be reduced. It has many features such as:

In the present invention, a top plate pushing device for pushing up the top plate upward is disposed in the middle of the top plate conveyor, and an injection box having an opening that opens downward is provided above the top plate pushing device. The injection box includes a movable lid body that is removably attached to the opening side of the injection box and has holes that match the plurality of mold holes formed in the top plate, so that the opening can be opened and closed. An ejection chamber is provided, and a movable frame on which a plurality of nozzle units are arranged side by side is reciprocally disposed on the upper side of the ejection chamber so that the tips of the nozzles of the nozzle units can be viewed from the ceiling side of the ejection chamber. Furthermore, the plurality of nozzle units are connected via a link mechanism so that the spray angle directions of the nozzle units can be changed during the reciprocating process of the movable frame, thereby making it possible to apply oil to the mold holes in the top plate. When moving forward, the bottom and circular edge surfaces that are on the rear side of the mold hole in the transport direction of the top plate are coated, and during backward movement, the bottom surface and circular edge surface that are on the front side of the mold hole are coated. The inner surface of the mold cavity can be coated uniformly. In particular, when coating a vertical circular edge surface, by tilting the nozzle unit back and forth during the movement process, uniform coating can be achieved regardless of the size and depth of the mold hole. Further, since the nozzle unit is arranged on a movable frame and reciprocated, the number can be reduced to the minimum required number. Furthermore, since the oil is injected into the injection chamber, the oil does not turn into mist and scatter around, thereby improving environmental hygiene. In addition, this device has a top plate conveyance section, a top push-up device, an injection chamber, and an injection device arranged in a layered manner, so it can be configured compactly and the installation area can be reduced. Its contribution as a coating device is extremely large.
