Description

Device and procedure for packing articles.

The invention relates to a device and a procedure for packing items, especially items Small, preferably chocolate.

The machines that work according to the principle of two stops transport the item to be packed with the medium packing by a folding device (for example, box of folding), making the first folds of the packing medium Around the article.

During this, the packaging or portion corresponding packaging is fed intermittently by cycles, the individual portion of a band or similar being separated of the packing medium.

This is necessary, since the packing medium it is positioned approximately centered with respect to the article, for example on the top side of this one, before the item together with the packing medium is held by a unit of reception (for example, the stops) and impersonate the folding device.

Due to the subsequent transport movement of the article with the packing means by the folding device the area for the supply of the packing medium is blocked next by the part of the receiving unit that moves by The folding device. Only when this part has returned to its Starting position, the following packing medium can cross your motion path, that is, position approximately centered on the article.

Therefore, the following packing medium For the packing of the following article you can transport less than 50%, because otherwise it collides with the unit of reception.

There is a desire to increase the speed of Processing or packing of this type of machines.

To increase the speed of a machine this type, could increase the speed of movement of the receiving unit, for example, of its stop. Without However, such a speed increase is limited by accelerations and material stresses that occur in the machine and the efforts to which the articles.

Nor is a faster supply of packing or means of packing without problems, since a many of the materials used are susceptible to speeds variables and resulting efforts.

Alternatively, you might consider giving up approximately centered alignment of the packing medium Regarding the article. This, however, limits the selection of types of folding that can be done with a machine of this kind. Thus, for example, positioning is normally required. approximately centered of the packing means in the sense of supply of the packing medium to make a gathered fold,  letter, side, bottom, bag and tip, as well as a folding by folding with double turn etc., if you do not want to perform no additional folding in the folding unit. Therefore, if You want the packing device to provide a wide range of types of folding, the centered alignment of the means of packing in the sense of supply of the packing medium and the Article.

Therefore, the invention aims at provide a device for packing items that present a higher processing speed, providing the same time a plurality of types of folding.

This objective is achieved through device indicated in claim 1.

Because the device to pack items is provided with a receiving device, a folding device and a medium supply device packaging, the receiving device being with an article and with a packing medium positioned approximately centered in the article in the sense of supply of packing medium, and the folding device positioned so that one can move with respect to another, so that the receiving device passes through the article and the packaging means by the folding device, the receiving device and the device being configured folded so that they avoid the following packing medium, especially during the movement back to the position of heading, the folding device being a folding box configured so that it avoids the receiving device, being possible to feed the packaging or the packaging means continues, as it cannot collide with the device reception or folding, so there is no limitation of the capacity of the machine due to the delivery device of the packing medium Consequently, it is possible to increase the processing speed without anticipating others or several receiving and folding devices. In this case, the construction and structure of the device would be much more complicated and, consequently, would also increase its cost.

In addition, it results in a series of advantages additional. Thus, due to the continuous supply of means of packing is achieved a regular march of the packaging, so the corresponding packing medium can be positioned in a way optimal In addition, a constant voltage of the medium of packing, so you can avoid breakage etc. from the middle of packaging. This allows processing of packing media extremely sensitive and difficult to process otherwise, such as very thin sensitive packaging media such as aluminum or polypropylene sheets.

According to a preferred configuration, at least one part of the receiving device travels during its movement of return a return movement path that eludes the medium following packaging, and that is different from the trajectory of outward movement

According to another preferred configuration, the avoidance return movement takes place in the sense of Supply of the packing medium. By sense of supply of means of packaging means the direction in which the packing medium

According to another preferred configuration, the receiving device has two clamping units arranged opposite each other, receiving the article and the packing medium (or section of packing medium) between them for Pass them through the packing device.

According to another preferred configuration, at least one clamping unit is set to bypass during the return movement of the receiving unit packing medium next.

In this regard, the at least one unit of clamping can be configured to follow, in addition to the sense of movement through the folding device, a sense of deviation movement oriented approximately in shape transversal with respect to this one.

To do this, according to another preferred configuration, the at least one clamping unit can be fixed so rotating to a tree that can move in a sense of round trip movement The rotation of the clamping unit It can be done especially by means of a lever. Alternatively, the at least one clamping unit may be housed slidably in the direction of supply of the means of packaging.

Obviously, it is also possible to configure the folding direction such that the entire folding device, together with the receiving device, you can bypass the means of following packing.

According to another preferred configuration, the folding device is a folding box that preferably it has a modular structure, that is, its walls can adapt without much effort, by exchanging different zones, to the different types of folding and articles. It is understood that the folding box can also have walls provided with brushes, depending on the type of folding.

According to another preferred configuration, the box of folding is done in a divided way and can also present At least one rotating wall. Alternatively, the folding box It has at least one sliding wall in the direction of supply of the packing medium.

Therefore, according to a preferred configuration, according to which the wall of the mobile folding box, for example of swivel or slide shape, is configured so that bypass the receiving unit in the sense of supply of the medium packing, the folding box does not prevent the receiving unit can perform the diversion movement, so that a Compact structure with good accessibility.

For this purpose, the wall of the folding box it can be mobile by means of a lever, whose movement can be optionally coupled with the movement of the unit reception.

To allow maintenance and repair easy folding unit, this is done so that from the work position you can turn to a position of maintenance, for which a union is specially planned by spherical lever articulation. In this way, the setting of the lever can be maintained despite the possibility of rotation, and this can be coupled in a simple way with your drive

The aforementioned objective is also achieved by the method indicated in claim 17 for Packing items, which is specially done using the device described above, and comprising the following Steps:

-

receipt of the article along with a packing medium positioned approximately centered with respect to the article in the sense of supply of the means of packaging, by means of a receiving device,

-

folding the packing medium around of the article by a relative movement between a device folding and receiving unit, passing the device Reception, with the item and the means of packaging, by the folding device,

-

delivery of an item packed at least partly with the packing medium and

-

performing a movement by the receiving device and folding device, to bypass the following packing means, the folding device being a folding box (5) that performs a movement to avoid the receiving device (3, 4).

In a preferable variant of the procedure, the deviation movement of the receiving device takes place in a return motion path to bypass the medium of following packaging, which differs from the movement path outward.

More features, details and advantages of the invention result from the following description of an example of realization with the help of the drawings. They show:

Fig. 1 a detail of a section in direction vertical of a device to pack items in the area of the folding device with an article and the middle section of packing in the starting position;

Fig. 2 the detail of Fig. 1 after making pass the article through the folding device, making the receiving device and folding the movement of deviation, and

Fig. 3 the detail of Fig. 1 during the sequence of movements when passing the article through the folding device and return to the starting position.

Figure 1 shows a detail of a cut in vertical sense of a device designated by 100 as a whole,  intended to pack items 1 with a packing medium 2. In the drawings, the device 100 is oriented approximately vertical. It is understood, however, that a horizontal orientation, that is, the orientation lacks importance for the invention.

The device 100 comprises a unit of reception that has two clamping units 3 and 4 arranged opposite each other receiving article 1 and the means of 2 packing each other to make them pass through a device folding configured as folding box 5 to perform the first folding of the packing medium 2 around the article one.

Clamping units 3, 4 have respectively a stop 3A, 4A and an arm 3B, 4B. The arms 3B, 4B they are joined on one side with the stop 3A, 4A and, on the other hand they are housed in a mobile way, so that, to receive the article 1 and the packing means 2 with each other, can move one towards the other.

The arms 3B, 4B respectively have a arched shape, so that during a common movement of the articulation points of the arms in a trajectory of curved movement in the direction of arrow H, stops 3A, 4A move through the folding box 5. Obviously, you can also be provided a movement path rectilinear

The arm 3B of the clamping unit 3 which in the Figures is arranged below, is also coupled in a manner rotating in a tree 16, so that it can rotate in a direction along the arrow R.

The packing medium is supplied laterally through a packing supply device 9, for what which means of individual packing 2 is separated from a band of continuous packing by means of a rotating blade 10, and positioned on a table for packing means 11.

The table for packing means 11 has a suitable opening 8 whereby the clamping unit 3 can press article 1 from below against packing means 2 or against the opposite clamping unit 4.

The packing medium 2 is positioned oriented approximately centered in the sense of Z supply of the packaging, before being collected, together with the Article 1, by clamping units 3, 4. Depending on the type of desired folding, the packing means 2 can also be oriented in transverse direction with respect to the supply direction Z of the packaging (that is, in the visual direction of the figure), so centered or off-center (for example, bag folding) with with respect to article 1.

The folding device made as a box folding 5 is configured in a modular way, that is, its walls 6, 7 in which the first folds take place, can disassemble and change with few removable parts to adapt the folding box, for example, to the size or shape of the articles. It is understood that they can also be removable and interchangeable the other walls provided eventually.

The wall 7 is a wall arranged in a way rigid and adapted to the arched movement path of the Article.

Wall 6, however, is configured so swivel It can be turned in the direction of arrow W using a lever 12 (see Figure 2). In this way, the wall 6 can yield to the clamping unit 3 that rotates in the direction of the arrow R.

The movement of the lever 12 is coupled, to through a spherical joint (not shown), through a corresponding gear, with the movement of the units of clamping 3, 4, especially arm 3B of the clamping unit 3. The spherical joint allows to move the folding box 5 from the operating position to a maintenance position turned towards above without having to separate the lever 12 from the drive or set it again after turning it back to the position of service.

The drive of the receiving unit and the folding device is done through a common engine, whose movement multiplies through gears and trees adequate.

In the Figures only the walls 6, 7 of the folding box, but it is understood that according to the type of folding there may be other walls, for example, parallel to the paper plane Correspondingly, they can be provided Also walls with brushes.

In addition, the device 100 comprises a evacuation device 13 that article 1 receives after its passage by folding box 5 and supplies it to other processing (for example, final folding) (see Fig. 2). To this end, the evacuation device 13 has opposite clamps 14, 15 that hold article 1 sideways, so that they do not collide with clamping units 3, 4 of the receiving unit.

Next, it is described, especially with reference to Fig. 3, the development of the packaging of an article 1 with a packing means 2, omitting the packing means in the Fig. 3 for clarity. In addition, the development of the movement originated is represented in dashed lines.

In the first step you start from the position of Item represented in Fig. 1. Article 1 is held together with the packing medium 2 positioned approximately centered on it, between the clamping units 3, 4 of the receiving device, next to the folding box 5.

Then they pose as the folding box 5 to the other side, during which the means of Packing 2, guided by the walls of the folding box, sticks around article 1 for relative movement. During this, the clamping units 3, 4 with article 1 and the means of packing 2 follow the arched one-way movement path (direction of arrow H) by the folding box 5.

Afterwards, the reception or delivery of the Article 1 packed at least in part with the packing medium, at evacuation device 13, for which article 1 is attached laterally by clamps 14, 15.

Now, first, the clamping unit 3 It moves back to the starting position. During this movement return of the receiving device, however, does not follow the one-way movement path but a trajectory of return movement that avoids the following packing medium, and which is different from the one-way movement path.

To do this, arm 3B of the clamping unit 3 not only moves backwards in the opposite direction to the arrow H, but is additionally rotated in the direction of arrow R, so that the clamping unit 3 avoids the packaging means that it follows in the sense of supply Z. In this way, the packaging or Following packing medium can still be transported continuously for the next article throughout the entire sequence described above. The turn in the R direction is done by the turn of arm 3B around tree 16.

Since, during the backward movement, the clamping unit 3 is located inside the folding box 5, it has to bypass the clamping unit 3 to avoid a collision. For this, the wall 6 can be rotated in the direction of the arrow W, by means of the lever 12, this being coupled movement, in the present example, with the movement of the unit clamping 3. A movement independent of the clamping unit

As soon as clamping unit 3 arrives below of the supply path of the packing medium, that is, under the table for packing means 11, and stop crossing the Supply of the following packing medium is rotated towards back in the opposite direction of the arrow R. Then the clamping unit 3 can take the starting position and will be Ready to receive a new article.

As soon as article 1 has been evacuated from the zone of the second clamping unit 4 by the device evacuation 13, this can move towards the first unit of clamping 3 to "receive" a new item and a means of packaging. The process can start again.

Throughout the process, the packaging can continue to be transported continuously, since the middle of packing, separated by the blade 10 cannot collide with the clamping unit 3.
