Description

[Detailed description of the invention] The present invention relates to a device for stamping substances having a similar consistency.

To understand the present invention, we will provide some general information about the latest technology of soap stamping machines. The theories must first be made: the current and popular format is disk or disk. The axis of rotation is the feed and perpendicular to the direction of the soap's journey on the take-out belt, and It is called a rotating disk type.

A rotation in which the axis of rotation is parallel to the travel direction of the soap on the feed and take-off belts. There is another family of machines that has elements called trochanters, and this machine's One group is called the rotor type.

The feature that distinguishes the two groups described is that the disc type is equipped with a large number of molds. This is because the disk diameter quickly grows too large and results in This is because the inertia of the fruit poses significant handling and mechanical problems and therefore On these machines, increasing production increases processing speed without changing the number of molds. This is achieved by

This group of machines is therefore called the "fast" type.

In a rotor group, the number of forming molds can theoretically increase infinitely along the main axis of the rotor. Possible, but would this not increase the diameter and therefore the inertia of the soap bar? It is et al.

In fact, at the current state of the art, these rotor machines only have one or two rotations. Limited to eight molds placed on the trochanter. Therefore, the increase in production changes the speed This is achieved by increasing the number of molds without increasing the number of molds. Therefore this is better Call a group of horns ``low speed uJ!-''.

Speed, expressed in number of strokes per minute, is defined as high speed or disk speed, depending on the format. 100:150 for machines and for low speed or rotor machines is 50:60.

The invention refers to machines belonging to the low speed or rotor type group.

Currently produced stamping machines of this type exhibit the following problems: 1) High number of forming halves: i.e. a single rotor on the rotor for each piece to be formed. Instead of having mold halves, there are two sets at 180° for each soap piece; There are therefore three mold halves, two for feeding and stamping. , the other at 180° to the first two performs other operations such as ejection and cleaning. Let's do it.

2) Rotors with mold halves cooled by cooling fluid always rotate in the same direction This creates a sealing problem for the cooling fluid.

3) Due to the lack of a transfer suction unit, it is difficult to send bar soap to be stamped. Although difficult, as this transverse molding half moves horizontally, the stamping The piece to be stamped is removed from the feed belt in the same motion reaching the highest point in the motion. I'll take it.

The aim of the invention is to reduce the number of mold halves for each part to be stamped and to reduce the cooling fluid seal. It not only saves the problem with holes, but also helps in feeding similar bar soaps.

The aforementioned aim is achieved as specified in claims 1 and 2. Other advantageous arrangements are explained in the subsequent claims.

The invention will be better explained on the basis of exemplary embodiments shown in the attached figures, in which: Keep: Figures 1, 1a and 1b are a series of stamps in three non-limiting applications. Showing the axonometric projection of the ping machine; 2 to 5 are schematic cross-sectional views of the embodiment according to FIG. The sequence of the stamping process can be deduced.

In terms of numbers, the components of the system are defined as follows: Number 1 indicates a stamping slide with forming half 9, whereas forming half 1 0 gives a radial movement with respect to the rotor 2 on which it is mounted. In particular, (non- In the embodiment shown, the mold halves 10 are set below the mating mold halves 9. As the mold is cut, the mold halves 9 move from the top to the bottom and vice versa.

The number 3 indicates the means for gripping the piece S1 to be stamped, which may in particular include a suction part. good.

The numeral 4 indicates means for grasping the stamped piece S2, which means e.g. It may also include a group of suction parts.

A punch plate 5 is envisaged for cutting off excess soap ES.

The number 6 indicates the feed belt for the piece S1 to be stamped, and 7 for the stamped part S1. 8 shows the take-out belt for the removed piece S2, and 8 is the take-out belt for the surplus soap ES. Indicates the

FIG. 1 shows a system for a non-limiting exemplary embodiment of simultaneous processing of two soap bars. This example shows 4, 6 or 8 pieces etc. for easy understanding. can be easily expanded in successive multiples for simultaneous processing of soap bars.

Figure 1a shows an apparatus for processing 4 soap bars at the same time, Figure 1b shows an apparatus for processing 8 soap bars at the same time. 1 shows an apparatus for processing soap bars. As can be seen from Figures 1a and 1b, In the case of four pieces at the same time, a single rotor 2' supporting two double mold halves is be. Two feed belts 6 and a plate 5' for the four pieces are also envisaged. . For simultaneous stamping of 8 parts, preferably two offset rotors 2 ', each capable of processing four soap pieces.

In this case there are four feed belts 6.

Operation of the proposed machine with particular reference to FIGS. 2, 3, 4 and 5 An explanation of how the cycle works follows. Obviously all this behavior is is repeated for a set of mold halves. Soap piece $1 to be stamped is already cut They arrive at the machine on the feed belt 6 (Fig. 2), and are transferred to the feed adsorption section 3. It is then removed (FIGS. 3 and 4) and transferred to the rotating mold half 10 ( 5 and 2). The lowering stroke of the transverse forming half mold 9 (Fig. 3) is the final shape. Resulting in the shaping (or stamping) of the soap bar taking S2, the excess soap ES causing it to be ejected from the mold half. Stamped piece S2 and surplus soap The ES is attached to the lower mold half 10 by a method not covered in this invention. It remains as it is, and is transferred to the appropriate position by rotating the rotor 2 by 90 degrees, and the suction unit 4 (Figure 4). The suction part 4 is drawn in from the rotor 2 (Fig. 5), and the pump Cut off the excess soap ES through the plate 5 (Fig. 5), and remove the excess soap from the belt. 8 (Figure 5). The extraction suction part 4 continues its movement and rotates by 90°. Place the stamped soap on the stamped piece removal belt (Figure 2) ). After the rotor 2 (Fig. 5) passes the stamped soap S2 and the surplus soap ES, After 90" rotation, the mold returns to the position shown in Figure 2 and is carried by the suction unit 3 and rotated. A stamping piece S1 is received which is placed on the mold half 10 (FIG. 2). Like this The kuru is completed and repeated anew as described.

Feed and take-out suction unit uses vacuum to hold soap before or after stamping do. During detachment of the pieces, the vacuum is turned off and compressed air is blown to aid in removal. true Both air and air are controlled by solenoid valves not shown.

Flexible tubes (not shown) carry the necessary process fluids, i.e. cooling fluid, air and Provided to convey vacuum to the transverse (top) and rotating (bottom) mold halves. Ru. Since the rotor reciprocates, it is possible to use the tube, but before the invention In the produced model, the rotor always rotates in the same direction, so it is possible to use a tube. However, a rotating seal is necessary and must carry three fluids at the same time. This poses a structural problem.

The movement of the individual parts will be explained in more detail below = 1) Stamping slide It reciprocates in a radial translational motion with respect to the trochanter; in Figure 2 it starts its motion. At this stage, the descending forming half mold 9 and the retracting feeding suction part 3 are drying out from each other. Care must be taken not to interfere; Figure 3 shows the stamping operation. , is shown stationary in its highest position in Figures 4 and 5, and other parts are Wait for the material to finish its movement.

2) Rotor: In Figures 2 and 3 the pieces are stamped and the stamp pin It is shown standing still waiting for movement; Figure 4 shows a 90" counterclockwise rotation. After rolling, stand still and wait for the pick-up suction unit to pick up the stamped piece. Wait; in Figure 5, to return to the position in Figure 2 to receive the soap piece to be stamped. Piece S1 stamped by one rotor 2 making a clockwise rotation of 90'' Before being in the correct position to receive the stamp, the feed suction unit 3 with the piece S1 to be stamped is It should be noted that it is already in motion.

3) Feed suction unit: In Figure 2, the feed suction unit 3 holds the piece S1 to be stamped on the rotor. It can be seen retracting from the molding half after being placed in the molding half; at this stage It is necessary to make sure that the molding half mold 9 to be drawn and the feeding suction part 3 to be retracted do not interfere with each other. ; In Figure 3, the feed suction part after 90° rotation and backward movement is the stamping part. This is where the piece is removed; in Figures 4 and 5, the suction part that rotates 90 degrees is , conveying the part towards the lower mold half 10. Adsorption part and rotor come together at the same time Move towards the point and place the piece S1 to be stamped below.

4) Take-out suction unit: In Figure 2, the suction unit places the stamped piece S2 on the belt 7. Rotate and proceed (Figure 3) to take the stamped piece S2. (Figure 4).

The suction unit and rotor arrive at the gathering point at the same time and take the stamped soap S2. (Figure 4). FIG. 5 shows the extraction belt 7 with the piece stamped with the suction part. 5 shows the excess soap ES being cut off by the punch plate 5 as it returns towards; The suction part continues to move backward and rotates 90 degrees clockwise to remove the stamped piece S. 2 and place it on the belt 7 (Fig. 2).

5) Punch plate 5: This is stationary.

6) Feeding belt: This is a suction part that moves jerkily to feed the soap piece to be stamped. Bring it to the correct position as taken by 3. The exact location of the pieces is shown in the diagram. Determined by the immovable soap stop not shown, for which the soap stops.

7) Removal belt for stamped parts: This moves at a constant speed and The placed pieces are carried to the next operation by the pick-up suction unit.

8) Excess soap removal belt: This moves at a constant speed and is cut by a punch plate. Remove any excess soap that has been dropped.

9) Transverse (or upper) molding half and rotating (or lower) molding half: The first moves integrally with the stamping plate 1, and the second moves with the rotor 2.
