DE202004006594U1 - Cutting machine, for slicing bread rolls and baguettes, has two U-shaped shafts to carry them through on belts/chains, with a horizontal center circular blade cutting into both shafts - Google Patents

Abstract

The cutting machine, to slice bread rolls and long baguettes, has two parallel U-shaped shafts (S1, S2) of equal length and size, bonded together longitudinally. A horizontal circular blade (M) has each half cutting across the shafts. The blade is powered by a lower electromotor (A). The motor and the blade can be raised and lowered by a lifter (V) for height settings. A powered belt or chain (T), with grip tines (G) at intervals, pushes the rolls/baguettes through the cutting blade.

Description

Known automatic cutting machines operated by an electric motor are for buns complex and therefore expensive. This is not least due to the fact that for the different in shape and size Buns and Baguette only one feed shaft is available. This has to be done by elaborate mechanisms for the respective Shape and size always changed can be. The requirement also requires different cutting thicknesses preferably to be able to adjust continuously further effort.

The cutting machine presented here has other, simpler techniques, is therefore less prone to failure, and saves space and because of its simplicity, it is also considerably cheaper manufacture. Band knives or double electric knives are not used in favor of a circular knife. These have been around for decades Tried and tested in slicers and bread slicers.

In the innovation described here cuts however, the knife is not vertical, but horizontal. The knife disc lies on the engine like a plate. Since both rolls and baguette one have a maximum width of 8 cm, is sufficient for cutting open or Slit only a half a circular knife of slightly more than twice the diameter. On this way two feed shafts are led, either both with bread rolls at the same time or one for bread rolls and the other for Baguette can be set up.

The feed chutes preferably consist of two U-profiles open at the top, the parallel, lengthways be connected to each other. Each profile has its own top preferably transparent cover through which the cutting processes are observed can be and which can be removed or folded up for cleaning. The Circular knife divides a shaft horizontally with each half. For example, a shaft especially for the sharing of rolls and the other for Baguette of any length can be set up or, with a cutting insert both shafts only for Bun, the cutting capacity therefor be doubled.

With a diameter of the circular knife of only 18 cm needed the machine only has a total width of just over 20 cm. The Supply of bun to the knife is carried out by an electromotive belt or a chain that is in the outer side wall or on the floor moved towards the end of the shaft and at the end under pulleys runs back down the shaft floor. Out this belt or chain protrudes horizontally from the shaft, like fingers, at least one of which is passed under the circular knife and one or two over the knife passed become.

One presses under the lid spring-loaded small pressure plate, which is in front of the knife, the Tips of baguette or bun with light pressure on the bottom of the shaft. So it becomes a more even, horizontal one Guaranteed cut.

The manhole cover points at the beginning an opening upwards in which the buns individually, one after the other. Those on the tape They slide their fingers through the knife hidden in the shaft. The distance between the fingers and the speed of the tape are set so that a safe insertion of rolls between two sliders possible is.

When measuring various bun and baguette was found to be different in height deviate from each other by a maximum of 2 cm. Preferably have the cut Lower part one and the upper part two thirds of the total height. About the relationship at different heights to maintain, the knife only needs one adjustment option of about one centimeter. This process can be caused by an outward protrusion Lever located under the engine. He raises or lowers the motor, and thus the knife, to the desired cutting thickness.

Since two or three settings are sufficient, it is not necessary a complex adjustment device. The shafts can pass through in length a small "guardrail" that is located inside , longitudinal, on the outside of the shaft is made narrower. If this plank is an adjustment that can be made from the outside having.

The propulsion of long baguettes is done manually by a slide in the longitudinal direction, which is in the lid is reasonable. This can be followed by a hinge across the shaft can be folded up and has two rows of needle pins on the underside on, when lowering through two parallel slots in the lid press into the top of the baguette. In this way, the baguette can be moved lengthways through the knife pulled and pulled out after the slider is folded up become.

Summary.

Electric cutting machine for rolls and baguettes, characterized in that a rectangular, U-shaped housing open at the ends ( 1 u. 2 ) has a partition in the middle in the longitudinal direction, and thus in two long, horizontal shafts. 1 shows the front view, 2 the top view and 3 a section of the side view.

( 1 , S 1 u. S 2) is shared. A circular knife (M) is located horizontally in the shafts, half of which cut horizontally through a shaft.

The knife is through an underfloor Drive (A) driven. Motor with knife can be lifted (V) raised or lowered.

The shafts are each one with one preferably transparent cover completed. On the underside of the lids there is a pressure plate (Q) that runs obliquely backwards in front of the knife and that folds backwards by up to 45 degrees thanks to a joint at the front.

A compression spring always keeps the flap angled Position. Continuous cutting material is countered by this flap pressed the ground. The feed for the rolls to be cut or Baguettes can be done manually or by motor. In the left shaft (S 1) a motor feed is shown.

An electric motor operated conveyor belt or chain (T) on which at intervals Gripper fingers (G) are attached, pushes the material to be cut through the Knife. It is important to have a finger under the knife and one or more about the knife are attached so that the lower part does not cut can get stuck under the knife.

The belt / chain (T) runs covered behind an intermediate wall in the cutting direction above and back under the housing base. At the beginning the shaft has an opening (E) into which the bun be inserted in order to then be removed from the gripper fingers while the belt is running to be transported.

In the right shaft (S 2) 2 and 3 a manual feed is shown. It also enables a semi-automatic version of the cutting device. The plate P runs in the guide slots (F) and can be pushed back and forth like a slide with a button (K) via the gripping device ((K). Under the plate there are vertically attached needle pins.

The plate can be folded up in the joint (GE) ( 3 ). The plate is folded up before the material to be cut is inserted. After insertion, the needles press into the bread when folded down. Now the baguette or bread roll with the plate on the cover rail (F) can be pulled through the shaft and thus through the knife.
