Abstract

The invention relates to a device for cutting Gefürut with a guillotine-type cutting mechanism, which is constructed so that the frozen food is held during the cutting process. The aim is to reduce the energy consumption and the time losses when loosening and holding the frozen food block during the cutting. The object is to develop a block holding device so that an automatic stepless stroke limitation of the pressure plate takes place on the frozen goods passage height. According to the invention, a tactile feeler, which has a scanning edge and an impact surface, is movably arranged on the pressure plate of the block holding device. To trigger the control processes, there is a signal generator on the pressure plate. The impact plate of the Tastfuehlers is at an acute angle to the support plate of the frozen food block. The pivot point of the tactile error was chosen so that it is located on the pressure plate in the vicinity of the knife carrier. To limit the movement of the Tastfuehlers a stop on the pressure plate is attached. The impact surface of the Tastfuehlers is formed from an acute-angled molding. Energy- and time-consuming Hube the block holding device to the end position are avoided.

Description

'Field of the invention

The invention relates to a device for cutting frozen food with a guillotine-like cutting mechanism, which are usually constructed so that the food to be cut is held with a device during the cutting process.

Characteristic of the known technical solutions

The cut-to-size frozen food is in a variety of geometric dimensions depending on the technology in the processing plants, so that the block holding device to keep each frozen food block must be driven so high, .that the subsequent frozen food block can slip «

In the working process, this means that the block holding device must perform an idle stroke in the solution phase above the frozen food block "The idle stroke is the maximum height difference of the frozen food blocks"

These known technical solutions have the disadvantage that in the solution phase, the block holding device always moves into the upper end position to release the frozen food block. As a result, energy and time losses occur, especially in the case of small frozen food blocks, which restrict these machines in productivity.

Object of the invention € 1 $ 7

The aim of it is to reduce Erfindimg _s energy consumption and the loss of time when releasing and holding the Gefriergutblockes while cutting "

Explanation of the essence of the invention

The invention has for its object to develop a block holding device so that an automatic Stufenloee stroke limitation of the pressure plate is carried out on the Gefriergutdurchlaßhöhe. ,

According to the invention the object is achieved in that on the pressure plate of the block holding device, a touch probe, which has a sensing edge and an impact surface, is movably disposed *. To trigger the corresponding control processes, there is a signal generator on the pressure plate or on this festverbindenen guide frame, which is actuated by the feeler «The impact surface of the feeler is at an acute angle to the support plate of the frozen food block * Preferably, the pivot point of the probe was selected that it is located on the pressure plate in the vicinity of the knife carrier © To limit the movement of the touch probe, a stop on the pressure plate attached The impact surface of Tastfühlers is preferably formed from an acute-angled molding «By this solution is achieved j that the pressure plate of the block holder device only so far raises that the frozen food block can slip "energy and time-consuming strokes of the block holding device are thus avoided to the end position"

Embodiment.

The invention will be explained in more detail with reference to an embodiment _&.

Figure 1 Schematic side view of the Sehneidmechanismus and the block holding device in section

Pig 2 Scheme of the complete block holding device (front view without Sehneidmechanismus)

The block holding device consists essentially of the pressure plate 1 and a movable feeler 2, whose fulcrum 3 is located on the pressure plate 1 Furthermore, on the pressure plate 1, a signal generator 4 and a stop 5 mounted addition also still belong to Blockhaltevor · direction, a torsionally rigid frame, formed by the cross-beam 6 and the guide rods 7 and 8, which are supported in the guide bearings 9, »With the last cut, the block holding device assumes the starting position« Here, the pressure plate 1 has taken the lower position * Thus, the signal generator 10 in the starting position actuated by the switching lug 11 on the crossbeam «,

If now a frozen food block 12 on the inclined arranged support plate 13, it slips by its gravity against the feeler 2 _e This is so actuated that the switch lug 14 releases the signal generator 4 via the fulcrum 3 "This information from the signal generator 4 is turned on used the drive of the block holding device »It is the stroke of the block holding device by pressurizing the hydraulic cylinder 16 until the feeler 2 from the frozen food 12 is exposed · Thus, the pressure plate 1 freeze 12 free to slide down against the holding plate 17, the distance to the cutting edge of the knife carrier 15 the cutting disc thickness determined * The knife carrier 15 with the holding plate 17 is connected to the Quertravers.e 18 through the two guide rods 19 and also form a ver ~ 'torsion stiff guide frame * During the downward movement of the blade carrier 15 »initiated by the signal generator 20, success t the cut * At the same time, the block holding device is driven by the hydraulic cylinder 16 so that the pressure plate is placed on the frozen goods 12 and block with set pressure

this presses against the platen 13 "The lower switching point, which is formed by the signal generator 21 is set so that the cutting edge of the blade carrier 15 on the counter knife 22 the frozen goods 12 cuts safely * In the lower position of the blade carrier 15, signal generator 21 is actuated is also reversed, respectively, the block holder, d _e h ", the pressure plate 1 also dissolves from Gefriergutblock 12 when the touch probe 2 is not operated © This stroke of the block-holding" = device is carried out, however. only urn a set amount, which serves to ensure that the Gefriergutblock 12 is released and can slide down "1st However, during the lifting movement of the Me s ~ serträgers operated 15 of the touch probe 2, d _e tu, the nachrutschende Gefriergutblock 12 has different dimensions than the, which is just under the pressure plate 1, the lifting movement of the block holding device via the signal generator 4 continues until he releases the feeler-2 and slipped in the process further, these movements are repeated, "until the cropping frozen food is used up"
