The invention relates to an improved hydraulic feed for a system in which Goods, such as raw potatoes, are conveyed quickly and precisely through a cutting device and in which the product, for example a potato, is divided into a number of so-called middle cuts becomes, while at the same time the exterior or the outer shell parts of the potato of the more desired middle cut parts are removed.

In particular, the invention is an improvement to an apparatus in which the novel Combination includes the following sequential steps: Raw potatoes are put into one Reservoir filled, which with a circulation or return medium forming hydraulic Means, like water, is filled. A feed pump, which picks up the potatoes with water, feeds them the same into a goods accelerator, whereby the individual potatoes are separated from each other and then thrown through a cutter. This is with alignment or guide shoes provided, which are arranged in front of the cutting device so that they each potato along the Center the longitudinal axis of the flow exactly, so that each potato goes directly into the Cutting device is fed.

After the cutting process, the middle pieces of the shell parts of the potato are through Separating devices separated. Once separated, the trays become one side of a drainage trough and the middle parts passed to the other side thereof, the drainage trough separating the respective potato parts from the water. The water is then returned to the storage tank to be continuously supplied with new ones Loads of goods to be reused.

The invention relates in particular to the main mode of operation of such a device, namely on the alignment and centering of the goods immediately before they hit the blades of the cutting system without flowing past or losing part of what is available Pressure medium. The known centering devices are balanced in such a way that each side the same moves in the same proportion and by the same amount as the opposite Page. A centering of the liquid flow and the goods is brought about.

The operation of the known device is extremely satisfactory, the experience shows, however, that not the maximum impact energy or kinetic energy of the hydraulic Device for cutting goods,

Means was exploited. It has been found that when using the known cutting device and feeding device a certain part of the water at the central line or at the desired one Flow path flowed past, d. that is, certain amounts of liquid were against the outside the ladder elements or adjusters. Accordingly, the impact force became smaller than it would be if all the power of the hydraulic medium was in the central pipe and inside the baffles or adjusters would be included. In this case it would be full force, full thrust or the achievable pressure of the pumped liquid is fully utilized. The invention is therefore based on the following feature directional: the confinement of the flow of the control medium in restrictions within the adjuster, so that the full force of it gives a sharper and more precise impact on the cutting assembly causes, which is arranged immediately after the adjustment device, with essentially no funding passes by either side of the setting or control facilities.

It is therefore a primary object of the invention to provide an adjustment cutting assembly which by Control of the flow of the enclosed hydraulic medium in the center line by means of devices, which have an elastic tube within the adjuster or guide elements, the exercise the full force or full impact of the drive means in the appropriate direction in full Way causes, with no essential or

It follows that they are schematically shown in FIG. 4, any outward movement of the guide members may necessary slide. This table 78 is directly on the end plate 4 on the lower fork heads and accordingly welded on, as shown in FIG. 1 shown. 55 any resistance to this movement is immediate

The articulated mechanism that enables the corresponding inward or outward movement of the guide parts from the lower fork heads to the arms 98, 98 'and from these via the rollers 102, 102' to the mechanism is transmitted at any time to the adjacent adjuster or guide parts. Standing bars directly connected. As in Fig. 3 represent these lower fork heads 110, 110 ', which are placed below, is a vertical flange or extension 80 60 half of the one shown in FIG. 6, the guide parts shown are arranged directly on the upper and lower rod 35 and 37, respectively, are welded to corresponding ones in the same way. The opposite roller 120, 120 'is provided in the same way, the latter being mounted on the flange W on the upper and lower bearing journals 122, 122', which are welded on by spacer rods 36 and 38, respectively. Each part has any customary device, for example the joint movements in relation to each guide part, 63 Qaerzapfen or the like, can be held in their position, of course in the same way the other way round. In each case, the vertical supports 80, 8A 'are connected to a pivot point and not only respond to an outward movement of the guide parts with Läogsöanschen 84, 84' (FIGS. 1, 3), but also.

also to forces which are exerted on a common bumper 130. That bumper (Figs. 6 and 7) is slidably mounted in a bearing 135 to perform a reciprocating movement, which is their main support and in turn by a transverse arm 132 in FIG Is held in position, the cross arm being welded to the opposing spacer rods 37 and 38 is.

From Fig. 7 it can be seen that the hinge end of the bumper 130 is provided with a side flange 136 is provided, which has two parallel, spaced apart U-shaped parts 138 and 140 carries, the distance between which is large enough to abut the above-mentioned rollers 120, 120 'slidably. As shown in this figure, causes these rollers to move to the right or left a corresponding movement of the bumper with practically no friction as a result of this roller engagement 130 to the right or left, as indicated by the arrow in this figure. In the same way becomes the impact exerted on the bumper 130 on the rollers and the other elements described of the joint mechanism. Therefore, the whole movement of the two adjusters or guide parts stands in relation to one another, is interdependent and related to one another, so that the guiding devices move inwards or outwards over equal and proportional distances, regardless of whether a slightly greater pressure is exerted against one of the guiding devices than against the other. Through this the center setting of the arrangement is guaranteed.

Except for the storage in the bearing 135, the bumper 130 is in the same way on its opposite End supported by a bearing 150 which has an extension thereof from the guide assembly also allows, but the same with respect to the exterior of the unit closes watertight. This is caused by the said bearing bush 150, which is supported by the end wall 4 of the Housing is screwed, as in F i g. 7 shown. A bearing shell 151 is in direct engagement with the bumper 130, the bearing bush 150 is made waterproof by the pressure seal 154 and the Shell 151 is provided with seal 152 for the same purpose.

The protruding part 153 of the bumper 130, i. H. the outside of the housing of the adjustment device located part, is by means of a pin 160 with the fork 163 of a triangular cam plate 165 tied together. The pivot point of this cam is formed by the axis of a roller 168, which is mounted on the lower triangular edge of the cam by a pin 170. The roller 168 is mounted between two parallel surfaces, which by the inner edge of the projection 172 and the on a flange 180, which in turn is suitably welded to the end plate 4 or to others Manner attached, attached bearing surface 165 are formed.

The approach 172 is supported by an additional flange part 183, which under right Angles extends to the flange 180 and is attached to this, as in F i g. 1 shown.

The third position of the triangular cam is, for example, by a pivot pin 185 with the Diaphragm rod 188 of known type of air brake diaphragm 190 is pivotally connected. The compressed air brake diaphragm is mounted on the above-mentioned carrier element 183. Such Devices simply use the air pressure on one side of a sealed membrane to exert a spring load, d. H. to counteract any movement when applied Force is canceled. It goes without saying that other devices for generating a counter o pressure can be used against outward movement of the guide devices, for example Springs with a given spring force.

From the above description, the mode of operation of this device is for feeding and central Alignment of goods clearly understandable. The unexpanded or collapsed position of the elastic tube 45 and the two lateral adjusters 40 and 42 are shown in FIG. 3 shown. This condition there is one before the entry of the first

ao row of, for example, potatoes in the arrangement, which as a result of the enclosed hydraulic means exerted pressure as well as due to the speed or momentum of the is pressed by the means conveyed goods through the cutting device. While getting a potato Approaching the cutter, of course, the inner tube 45 is in the position shown in FIG. 4 position shown extended. This outward movement or expansion of the inner tube causes a corresponding effect Movement of the adjusters as the product approaches the outlet end of the device and impinges on the cutting element. The joint mechanism described above makes this Movement by an outward movement of the upper arms 98, 98 'and a corresponding movement of the lower forks and rollers 120,120 'and thereby a correspondingly wide movement of the bumper 130 toward the outlet end of the device or to the left in FIG. 7 added. These Movement also triggers the diaphragm rod 188 to be pushed downward (FIG. 1). With In other words, this outward movement of the two guide members 40 and 42 is from pushing the Diaphragm rod down and accompanied by a corresponding movement of the triangular cam plate. As shown in FIG. 1, this corresponding movement is indicated in dashed lines. When the pressure on the tube 45 is released, the compressed air acts on the sealed Side of the air brake diaphragm, a countermovement of the push rod 188 into its starting position back (shown in solid lines in Fig. 1) and related corresponding movements of the same associated elements in their in FIG. 3 layers shown.

It can be seen that by this hinge mechanism between the two adjustment plates 40 and 42 they are caused to move equidistantly with respect to an outward or inward movement and as a result of any expansion of the inner elastic tube 45. So is the goods at all times accurately and neatly averaged along the longitudinal axis of the unit so that its full impact force is directed exactly towards the center of the cutting device itself.

It is noted that although the inlet end of the elastic tube 45 is sealed against the ingress of water

509 507/99

tet, but the outlet end of the same is open and unsealed. The guidance systems keep how stated above, the central disposition of element 45 at each stage of the process, as in FIG F i g. 3, upright when the potato has not yet entered the unit. Though the outlet end is actually not sealed with the opening 15 of the end wall 4, it is nevertheless arranged in the immediate vicinity of this opening. It's going at great speed Water conveyed through the unit, and the liquid, which is located in the outside of the guide elements Part of the cylindrical housing 1 emerges has no meaning for the following reason: If this Water rises to a height close to the opening 15, it is through one of the water adjacent Lines 30 or 32 added and derived. This is done because the hydraulic means with the speeds used here a mode of operation of the tube 45 in the manner of a suction nozzle a ° causes. Any excess water near the opening 15 is due to this jet effect of the water and printed in one or the other of the outlet lines.

It is therefore evident that the interior of the cylindrical housing 1, with the exception of the water, which is pushed through the tube 45, at all times substantially free of substantial Amount of water is maintained. Therefore, the guide parts and the associated elements which control them, unaffected by the presence of water in or around them and accordingly speak better to every pressure or pressure change inside the Tube 45.

The arrangement described thus achieves the main objective mentioned, namely the utilization of the total force potential, which of the hydraulic used to convey the goods Medium is exercised as a means of properly slitting the goods on a cutting element. Indeed the mode of action is better than any previously known, and by creating sensitive Facilities that respond quickly and immediately to any movement of the guiding facilities respond, the central setting is also greatly improved in the same way.

While a preferred embodiment of the invention has been shown and described herein, it is It is clear that various changes have been made thereto without departing from the spirit of the invention will be körinen.
