Description

The invention relates to a conveyor carpet module and a conveyor carpet comprising a plurality of the above-mentioned modules.

Promotional carpets are well known in the art. Their use is very widespread in many areas, as they allow the transport of a very high number of objects, such as bottles or containers, at high speeds.

The known in the art conveyor carpet typically consist of several adjacent modules, two of which are connected via respective bolts. Each module has a support surface on which the objects to be transported rest during the carpet feed. Typically, the modules forming the conveyor carpets are made of plastic injection molding, for example of a suitable acetal resin.

Also known in the art are conveyor carpets in which the support surface consists of rolling elements, such as rollers, needles or balls. In this type of carpets, the modules define a receiving structure provided with further bolts on which the rolling elements are loosely mounted. The axis of rotation about which the rolling elements rotate is the axis of the further bolts and is perpendicular to the direction of advance of the carpet so that the transported articles move with some relative movement to the carpet.

This type of conveyor carpet is used under special conditions where it is desired to minimize the frictional force between the transported articles and the support surface. For example, this type of carpet may be used in the area of an automatic packaging line having a plurality of sequentially arranged workstations where different speeds of the articles are present at the exit from the various stations. In this case, with this type of carpet, it is possible to create variable "buffers" of objects between two adjacent stations.

A disadvantage of this type of conveyor carpet is that it is very loud due to the noise caused by the rotation of the plurality of rolling elements on the other bolts. Because while the rolling elements are typically made of plastic (for example, acetal resin as in the modules), the other bolts are generally made of a metal material, such as steel. The rotation of a very large number of plastic rolling elements on a steel bolt thus generates a very high noise in the environment.

Another disadvantage of this technical solution is that the rotation of a plastic rolling element on a bolt of metallic material creates some friction. It is clear that this is absolutely undesirable, in view of the fact that this solution is mainly used when the friction during the advance of the transported objects should be maximally reduced.

To remedy this disadvantage, a solution is also known in the art, in which the other bolts on which the rolling elements rotate are also made of plastic. By this solution, the noise generated by the rotation of the rolling elements can be limited and the friction between the latter and the bolts on which they are stored, minimized, a disadvantage, however, is that the carpet is weakened in the structure. Because plastic bolts have very different mechanical properties than steel bolts. In particular, they have much lower tensile / compressive strength, torsional / bending strength and wear resistance than a steel bolt.

This has the effect that it is not always possible to replace the other steel bolts with plastic bolts because, depending on the conditions of use, i. Depending on the nature of the products to be transported (size and weight of the products) and the feed rate of the products, it is necessary to consider in advance when assembling the conveyor carpet which type of stud is to be used. In other words, depending on the requirements of the user in advance to consider whether plastic bolts (by which the noise and friction can be reduced, but which have a lower strength) to be mounted or if it is necessary, steel bolts (louder, but also with greater strength).

One purpose of the invention is to provide a conveyor carpet module that is improved over the known type modules.

Another purpose is to provide a very flexible module intended for assembly with bolts in different materials, for example both plastic bolts and bolts of a metal material.

Another purpose is to provide a flexible conveyor carpet that can be adapted to the application requirements so that, depending on the application requirements, the structural rigidity required by the conditions can be offered, or one To provide carpet with limited noise and friction.

According to the invention, a module is provided as defined in claim 1 below.

module 1 includes at least a first shot 7 that in the first lateral receiving element 5 is executed, and at least a second recording 8th in the second lateral receiving element 6 is executed. It should be noted that the first recording 7 and the second shot 8th shaped in different ways and with each other and the first bolt 3 . 9 are aligned, so they each have a part, headboard 3a , a or end part 3b . 9b , take up. In module 1 According to the invention, it is provided that one of the two recordings, the first recording 7 or the second shot 8th , is shaped so that they have a positive connection with the head part 3a . 9a connects, and the other of the two shots 7 and 8th with a corresponding game for receiving the end part 3b . 9b is determined.

In the illustrated embodiment, the rolling means comprise 2 also at least several second rolling elements 30 which are arranged at least along a further row B parallel to and adjacent to said row A. The second rolling elements 30 are like rollers (cylindrical rollers) of the known type in the same way as the first rolling elements 20 shaped. In other, not shown, implementation forms, the second rolling elements 30 include any type of rolling element, such as balls or needles.

module 1 includes a second bolt 3 ' . 9 ' on which rotatably said second rolling elements 30 are stored, identical to the said first bolt 3 . 9 , Accordingly, also the second bolt 3 ' . 9 ' at opposite ends with the above-mentioned head part 3a . 9a and end part 3b . 9b Mistake. It should be noted that the second rolling elements 30 on the second bolt 3 ' . 9 ' turn it loose.

The first lateral receiving element 5 includes at least one more first shot 70 and the second lateral receiving element 6 includes at least one more second shot 80 , The further first shot 70 and the second shot 80 are shaped in different ways and with each other and the second bolt 3 ' . 9 ' aligned so that they each have a part, headboard 3a . 9a or end part 9a . 9b , take up. module 1 According to the invention provides that one of the two shots, the further first recording 70 or the second shot 80 , is shaped so that they have a positive connection with the head part 3a . 9a of the second bolt 3 ' . 9 ' connects, and the other of the two shots 70 and 80 with a corresponding game for receiving the end part 3b . 9b of the second bolt 3 ' . 9 ' is determined.

It should be noted that the shape of the first shot 7 is identical to the shape of the other second recording 80 , and the shape of the second shot 8th is identical to the shape of the further first recording 70 , In other words, each two of the four shots have the same shape according to a configuration in a cross and not in series (ie, the first shot 7 with the second shot 8th and the further first shot 7 with the second shot 8th ).

With reference to the first state of use according to FIGS. 1 and 2, it can be observed that the head parts 3a of the first bolt 3 and the second bolt 3 ' have a spherical shape. Consequently, also have the first shot 7 and the second shot 80 responsible for receiving the headboards 3a are determined, the same spherical shape (see better in the enlarged cross-section of Figure 2), so that the intended positive connection is possible. Arrow F1 shows the direction of insertion for the first bolt 3 in module 1 , after the first the end part 3b through the first shot 7 insert and then the first bolt 3 push so far until the end part 3b in the second shot 8th passes and the headboard 3a about a positive connection with the first shot 7 combines. Similarly, arrow F2 shows the direction of insertion for the second bolt 3 ' in module 1 , after the first the end part 3b through the second shot 80 insert and then the second bolt 3 ' push so far until the end part 3b in the further first recording 70 passes and the headboard 3a over a positive connection with the other second recording 80 combines. In other words, the insertion directions F1, F2 of the first and second bolts 3 . 3 ' are the same and opposite to each other.

With reference to the second state of use according to FIGS. 3 and 4, it can be observed that the head parts 9a of the first bolt 9 and the second bolt 9 ' have a cylindrical shape. It should be noted that in this embodiment the headboards 9a For example, they may have been subjected to mechanical corrugation so that they are corrugated. Consequently, also have the second shot 8th and the further first shot 70 responsible for receiving the headboards 9a are determined, the same cylindrical shape (see better in the enlarged cross-section of Figure 4), so that the intended positive engagement is possible. It should be noted that at the headboards 9a executed corrugation is an aid for the production of the necessary form fit with oversize. Arrow F1 'shows the insertion direction for the first bolt 9 in module 1 , after the first the end part 9b through the second shot 8th insert and then the first bolt 9 push so far until the end part 9b in the first shot 7 passes and the headboard 9a about a positive connection with the second shot 8th combines. Analog arrow F2 'shows the direction of insertion for the second bolt 9 ' in module 1 , after the first the end part 9b through the further first recording 70 insert and then the second bolt 9 ' push so far until the end part 9b in the second shot 80 passes and the headboard 9a about a positive connection with the other first recording 70 combines. In other words, the insertion directions F1 ', F2' of the first and second bolts 9 . 9 ' are the same and opposite to each other. It should be noted that the insertion directions F1 'and F2' in this second deployment configuration are equal to or opposite to the deployment directions F1, F2 of the first deployment state.

It should be noted that the bolt pairs 3 . 3 ' and 9 . 9 ' are made with materials from the following selection group: plastics, such as acetal resins or self-lubricating plastics, metal alloys, such as stainless steel, metal materials.

Thanks to the invention module can 1 different bolt pairs 3 . 3 ' and 9 . 9 ' include, which are completely interchangeable with each other.

For example, in the first use state, the first bolt is 3 and the second bolt 3 ' made with a suitable acetal resin or a self-lubricating plastic. In this case, the bolts can 3 . 3 ' for example by injection molding just like module 1 can be manufactured and therefore can the headboards 3a Once the shape of the plastic injection mold is selected, the desired shape can be given in a very simple manner.

In the second state of use, however, are the first bolt 9 and the second bolt 9 ' made of stainless steel. In this case, the bolts 9 . 9 ' made by suitable mechanical machining, which is a corrugation of the head parts 9a enable.

Consequently, module is 1 According to the invention very flexible, since the rolling means 2 No matter on a pair of bolts 3 . 3 ' made of plastic, if noise and friction during operation of the conveyor carpet to be limited, as well as on a pair of bolts 9 . 9 ' can rotate from a metal alloy, if an increase in the mechanical strength properties of the bolt is desired. It should be noted that in operation the replacement of bolts made of a material 3 . 3 ' against other bolts made of a different material 9 . 9 ' is very easy and fast.

The first lateral receiving element 5 includes a first part 5a in which the first recording 7 is executed, and a second part 5b in which the further first recording 70 is executed. The first part 5a has a first thickness S1 and the second part has a second thickness S2. The first thickness S1 is less than the second thickness S2. Analogously, the second lateral receiving element comprises 6 a corresponding first part 6a in which the second shot 8th is executed, and a corresponding second part 6b in which the further second recording 80 is executed. The corresponding first part 6a has another first thickness S1 'and the corresponding second part 6b another second thickness S2 '. The further first thickness S1 'is greater than the further second thickness S2'. In particular, it is pointed out that the first thickness S1 is identical to the further second thickness S2 'and the second thickness S2 is identical to the further first thickness S1'.

This causes the parts 5a and 6b in which the first shot 7 or the second recording 80 which are identical to one another, are of the same thickness (S1 = S2 '). This configuration is advantageous because the operator instantly visually recognizes the parts to which the pin pair 3 . 3 ' is to be used according to the corresponding Einsetzrichtungen F1, F2.

Analog have the parts 5b and 6a in which the further first recording 70 or the second recording 8th , which are identical to each other, are made the same thickness (S1 '= S2). This has the advantage that the operator immediately visually recognizes the parts on which the bolt pair 9 . 9 ' according to the corresponding Einsetzrichtungen F1 ', F2' is to be used.

The receiving means also comprise at least a plurality of first receiving elements 10 and at least several second receiving elements 11 , The first recording elements 10 are along the row A and the second receiving elements 11 arranged along the further row B. The first recording elements 10 and the second receiving elements 11 are between the first lateral receiving element 5 and the second side receiving element 6 positioned with a certain distance from each other so that they are from the first bolt 3 . 9 and the second bolt 3 ' . 9 ' can be crossed.

The first recording elements 10 and the second receiving elements 11 are offset from each other so that none of the first receiving elements 10 side by side with one of the second receiving elements 11 located.

Because each of the first recording elements 10 between two first rolling elements 20 and each of the second receptacles 11 between two second rolling elements 30 it is clear that the first rolling elements 20 offset to the second rolling elements 30 are. This is advantageous because in this way arranged on two adjacent rows A, B rolling elements 20 . 30 uniform over the entire longitudinal extent of the module 1 (as can be clearly seen in the plan view of Figure 6), so that the formation of areas without rolling elements is prevented, which could slow down the flow of transported on the conveyor carpet items.

module 1 includes connecting means 12 , the several, equally spaced eyelets 13 which extends longitudinally between the first lateral receiving element 5 and the second side receiving element 6 extend. The variety of eyelets 13 is laterally on opposite sides of the module 1 attached, and each of the eyelets 13 includes a through hole 14 which is arranged so that it comes from a connecting bolt 15 (visible in Figure 8) can be traversed.

Every eyelet 13 has a pointed arch shape. This shape is particularly advantageous because the eyelets 13 thanks to the upper pointed end, when the conveyor carpet around the pulley 16 wraps the spaces between two adjacent modules 1 . 1' . 1'' Completely fill in so that the risk for an operator to injure his hands is minimized.

As can be clearly seen in pictures 1, 3 and 7, the module according to the invention can 1 . 1' . 1'' several assemblies 1a . 1b which are arranged so that they can be assembled to the module. The assemblies 1a . 1b comprise the same elements and may have different longitudinal dimensions. It should be noted that the total longitudinal extent of the assemblies 1a . 1b the longitudinal extent of the module 1 . 1' . 1'' equivalent.

In an alternative embodiment not shown, the module comprises 1 . 1' . 1'' a single assembly extending longitudinally along the length of the module.

Referring to Figures 5, 6 and 8, there is a conveyor carpet 100 (In particular, a part thereof) according to the invention, which is arranged so that it can transport objects, and a plurality of modules 1 . 1' . 1'' according to the invention and a plurality of connecting bolts 15 includes, which are arranged so that in each case two adjacent modules 1 . 1' . 1'' get connected.

Thanks to the invention, a module 1 . 1' . 1'' provided, which is very flexible, since it has two different bolt pairs 3 . 3 ' and 9 . 9 ' can work, each pair of bolts is made with a different material.

Another advantage of the modules according to the invention is that it is possible to use different bolt pairs 3 . 3 ' and 9 . 9 ' to mount, with which the carpet can run quickly and easily. Another advantage of the promotion carpet 100 According to the invention, it can be adapted to the application requirements in order to provide the structural strength required by the conditions, the first and second bolts 9 . 9 ' made of a metal alloy, or alternatively for limiting the noise and the friction by the rotation of the rolling elements 20 . 30 the first and second bolts 3 . 3 ' , made of plastic, are used.
