Abstract

The brush production machine (1) has a brush body-receptacle (11) having circumferential transport device (2) for transporting brush bodies (3). A brush body-feed area (14) is provided for manual insertion of the brush-body in the brush-body receptacle by an operator (12). The transfer devices (17a,17b) are assigned to the feeding devices for feeding a brush body from the transport device and back to the transport device.

Description

The invention relates to a brush-making machine with a brush body receptacles having, circulating transport device for transporting brush bodies, which are assigned at least one stuffing device for stuffing bristle bundles in bundle receiving holes of the brush body and at least one post-processing device for processing the bristle bundles.

From the DE 196 25 063 A1 For example, such a device is known, with which bundles of bristles are stuffed into bundle bodies and the bundles of bristles are processed on a finishing machine, for example sheared off and / or ground. The transport of the brush body between a stuffing device and the post-processing machine takes place by means of a workpiece holder having transport device. For stuffing the bristle bundles into the brush bodies, the brush bodies are removed from the transport device and transferred to the stuffing tool.

A similar device is in the DE 196 44 233 A1 described. Again, brush body are transported on a rotating feed device to a stuffing tool, removed from the feed device and fed to the stuffing tool for stuffing the bristle bundles and then transferred back to the feed device to be transported to other processing stations.

From the EP 0 563 419 B1 Known is a method for producing brushes in which brush bodies are fed into a carrier part with a conveying device a stuffing tool, wherein the brush is removed together with the carrier part of the conveyor for stuffing the bristle bundles in the brush body, which is complicated and thus costly.

All devices have in common that each devices for supplying unprocessed brush body as well as for removing finished machined brush body are required, which means a high design effort with appropriate space requirements and high costs.

It is therefore an object to provide a brush manufacturing machine of the type mentioned, which is structurally simple to manufacture and thus inexpensive and has a small footprint.

The solution to this problem according to the invention consists, in particular, in that a brush body supply area for manually inserting the brush bodies into the brush body receptacles is provided by an operator, that the stuffing device (s) respectively transfer devices for supplying a brush body from the transport device and to this are assigned back, and that an output device for transferring the finished stuffed and post-processed brush body is provided by the transport device in an output tray.

The brush production machine can thus be realized in a space-saving and structurally simple manner. Additional conveyor belts or devices for loading the transport device with brush bodies and for transporting the finished brushes are not required. The operator, or possibly another person, may replace the output tray when filled with finished brushes.

The brush manufacturing machine according to the invention is therefore particularly suitable in environments in which the brush manufacturing machine should be inexpensive, although continuous operation should be possible and this is possible by manual insertion of the brush body and corresponding manual removal of the finished brushes by one or more operators.

It is expedient if at least one brush body tray is provided as a supply for unbeborn brush body on the brush body supply area. The operator can then continuously remove brush body from the brush body tray and insert it into the brush body receptacles of the transport device. Another person may refill more brush bodies into the brush body tray or replace the brush body trays with full trays when empty.

In order to enable a simple insertion of the brush body in the brush body receptacles, and on the other hand to ensure a secure grip of the brush body in the brush body receptacles during transport, it is advantageous if the brush body receptacles have clamping clips for receiving the head of a brush body.

It is particularly expedient if a device for holding the clamping clips in the open position is provided in the brush body feeding area. The operator can then insert the brush body, without opening the clamps or use the brush body, for example, against a spring force in the clamps of the brush body shots. On the other hand, the tensioning clamps automatically get into their closing position, which clampingly holds the brush body, as soon as they reach the Leave brush body feed area by advancing the transport device.

The device for holding the tensioning clamps in the open position can be, for example, a strip along which an actuating element of the tensioning clamp is guided and acted upon. Leaves the brush body receptacle with the clamp the brush body supply area, eliminates the application of the actuator, which is then returned, for example, by a compression spring in a rest position and the tensioning clamp is thus brought into the closed position.

Thus, the brush body after inserting are still held securely clamp and can not fall out of the brush body receptacle, a support band for the free brush body ends can be provided in the brush body supply area. The brush body is then held in two places, namely in the head area by the brush body receptacle and in the handle area by the support belt. The support belt must be provided only in the area in which the tensioning clamps are in the open position. Once the clamps of the brush body receptacles are closed, the brush body are held firmly in these and an additional supporting or holding is no longer necessary.

The support belt preferably moves at the same speed as the transport device to prevent friction of the brush body on the support belt and thus damage.

The distance of the support belt to the conveyor belt as well as the vertical position of the support belt may be adjustable to adapt to different brush body.

In order to ensure a precise insertion of the brush body in the correct position, the support belt may have lateral guide elements for the free brush body ends. On the one hand, these guide elements facilitate a straight-lined insertion of the brush bodies into the brush body receptacles and, on the other hand, prevent the brush body from slipping during further transport.

A preferred embodiment provides that the transport device has individual chain links, on each of which at least one brush body receptacle can be fixed. This allows a particularly simple construction of the transport device and a flexible configurability. The chain links can rotate along a chain carrier. By equipping the individual chain links with one or more brush body receptacles, the brush manufacturing machine can be quickly and easily adapted to different brushes to be produced.

For example, each chain link may have two brush body receptacles. The operator inserts an unbeborn brush body into each of the brush body receptacles. After transporting the respective brush body receptacle to a first stuffing tool of this brush body is removed there, fed to the stuffing tool and stuffed a portion of the bristle field. After this stuffing the teilbeborstete brush body is converted into the released by the operator brush body receptacle of a chain link, fed by advancing the transport device of a post-processing device and abraded the bristles of the partial bristle field. The chain link in question is transported further, transported past the brush body feed region past a second stuffing device and fed to it, where another part bristle field with longer bristles is stuffed. The brush body so completely dipped is returned to the original brush body receptacle of a chain link and thus transported again to the post-processing device, where now the newly stuffed bristles are ground. Thereafter, the brush body is implemented as a finished brush in the output tray, so that the relevant brush body receptacle, when it comes back into the brush body feed area, is free and can be equipped with a new, unbeborsteten brush body.

This principle is not limited to two stuffing devices. If a chain link has more brush body receptacles, a corresponding number of stuffing devices may be provided for stuffing a partial bristle field respectively, with the brush bodies correspondingly often circulating on the transport means until they are transferred completely stuffed with the dispenser into the output tray.

So that differently long partial bristle fields can be processed on the same post-processing device without being able to position the post-processing device and simultaneously treat brush bodies with differently long partial bristle fields, brush body receptacles with different heights can be provided for accommodating brush bodies with partial bristle fields of different heights ,

It is expedient if the transfer device (s) in each case a first Umlegeeinheit for removing one or more brush body from the transport device and for transferring the (the) brush body to an intermediate buffer or a rotary receiving a stuffing tool and a second Umlegeeinheit for covering a machined on stuffing tool brush body on the transport device. This allows a quick transfer of the brush body between the transport device and stuffing tool. In this case, individual brush body can be implemented. However, it is also possible for two or more brush body, which are arranged in juxtaposed brush body receptacles, at the same time to pass to an intermediate buffer, which allows a faster feed of the transport device. In this case, it is also possible to provide an intermediate buffer for the stuffed brush bodies into which the brush bodies are inserted from the stuffing tool and returned from this to the transport device.

It is expedient if a device for checking the filling status of a brush body receptacles is arranged downstream of the brush body feed region in the feed direction of the transport device. If the operator inadvertently forgets to equip a brush body receptacle with a brush body, this will be detected at the control device and at the stuffing devices, if the spilled brush body receptacle has been appropriately advanced, the duty cycle in question may be eliminated to damage or contaminate to avoid the stuffing devices. For evaluation and forwarding of the signals of the control device, a control unit may be provided which also controls the stuffing devices, the post-processing devices and the transport device.

So that the operator can insert the brush body into the brush body receptacles ergonomically and without fatigue, it may be expedient for the upper run of the transport device to be lowered in the brush body feed region. Regardless of the overall size of the transport device, where appropriate, the upper run can be arranged comparatively high to make room for the stuffing devices, their associated Umsetzzeinrichtungen and the post-processing facilities, then the brush body supply region can be arranged at a level which nevertheless a comfortable inserting the brush body allows.

It is expedient if the individual components of the brush manufacturing machine are arranged on a common console. The entire brush making machine can then be built as a unit on the console and packaged upon completion and delivered to the customer. There are no further assembly work required, so that the brush making machine must be connected only electrically and pneumatically and then ready for use. Specially trained technicians of the manufacturer are thus not required for the commissioning of the brush manufacturing machine.

Shut-off elements for separating the working area of the operator and the remaining areas of the brush-making machine may be provided in the brush body feed area. The operator is shielded by these shut-off elements from the other machine areas, in particular the stuffing devices and the post-processing devices, so that the reliability of the brush-making machine is increased and a possible risk of injury to the operator is reduced.

An embodiment of a brush manufacturing machine according to the invention is explained in more detail below with reference to the drawings.

It shows, in part schematized:

1 a perspective view of a brush manufacturing machine,

2 a side view of the transport device of the brush manufacturing machine 1 .

3 to 7 in each case a differently provided with brush-receiving elements chain link of the transport device.

One in total with 1 designated brush manufacturing machine according to 1 a circulating transport device 2 for transporting brush bodies 3 on. The transport device 2 has one of individual chain links 4 formed chain 5 on, attached to a chain carrier 6 is guided. The chain 5 will, as in particular in 2 it can be seen from a chain drive 7 with a motor 8th and a sprocket 9 that have a drive belt 10 interconnected, driven (arrow Pf1).

At the chain links 4 are according to 1 and 2 two brush body shots each 11 for receiving the head of a respective brush body 3 arranged.

An operator 12 ( 1 ) lays in a brush body supply area 14 brush body 3 from several brush body shelves 13 in the brush body shots 11 the transport device 2 one. This unbeborn brush body 3 be with the transport device 2 to one in the end region of the transport device 2 arranged first stuffing device 15a transported. Along the transport route is doing a device 16 for checking the filling status of a brush body holder 11 intended. With this device 16 is checked if in a brush body receptacle 11 a brush body 3 is held and optionally if this is already equipped with a partial bristle field. The measuring signals of the device 16 are evaluated with a controller, not shown, and to the stuffing devices 15a . 15b transmitted. This will prevent the stuffing equipment 15a . 15b a stuffing process is triggered, although no brush body 3 exists because, for example, the operator 12 accidentally a brush body shot 11 has left free.

At the stuffing device 15a becomes a brush body 3 with a first transfer unit 18a a transfer device 17a from his brush body intake 11 taken and in an intermediate buffer 20 to hand over. Are both brush body shots 11 a chain link 4 with unbeborn brush bodies 3 equipped, these can be handed over at the same time. The intermediate buffer 20 is rotatably mounted and after turning the intermediate buffer 20 180 ° can be a brush body 3 with an insert element 21 in a rotation recording 22 be handed over. Because the shooting 22 remains horizontal in the same position, the intermediate buffer must 20 be horizontally displaceable to successively juxtaposed brush body 3 from the intermediate buffer 20 to the rotation recording 22 to hand over.

By turning the rotary holder 22 by 90 ° passes the brush body 3 in front of the stuffing tool 23 with which a partial bristle field in the brush body 3 is stuffed. After turning the rotary holder again 22 90 ° becomes the partially brushed brush body 3 with a second transfer unit 19a back to the transport device 2 to hand over. The brush body 3 is in the illustrated embodiment, respectively in accordance with 1 and 2 left brush body holder 11 a chain link 4 of the lower chain run inserted.

The so partially stuffed brush body 3 be with the transport device 2 transported to the other end, where in a post-processing area 24 Post-processing devices not shown are provided, in particular for grinding and rounding of the bristles.

The teilbeborsteten brush body 3 go through the brush body feed area again 14 and arrive at the second stuffing device 15b at the brush body 3 passed in the first round. There are the teilbeborsteten brush body 3 as described above with a transfer device 17b to a stuffing tool 23 where a second partial bristle field, especially with longer bristles, is stuffed. Such a completely filled brush body 3 is in a free, in the example described right brush body recording 11 put back and gets back into the post-processing area 24 where the newly stuffed bristles are processed.

After processing the bristles are the brush body 3 as finished brushes on an output device 25 in an output tray 26 transferred. The output device 25 may for example have a slider or a transfer gripper. There are several output trays 26 provided on a bracket 27 rest. Full output trays 26 can be removed by another operator and against a blank output tray 26 be replaced. This additional operator can also brush body shelves 13 in the brush body supply area 14 fill up and the stuffing devices 15a . 15b supply with bristle and anchor material.

The brush making machine 1 may also be configured differently, for example, at both stuffing devices 15a . 15b same, complete bristle fields instead of a partial bristle field are stuffed, so that more brushes per unit time can be produced.

All components of the brush making machine 1 are on a console 28 arranged. This allows the entire brush making machine 1 fully assembled at the manufacturer and set up at the customer, without further assembly work to be done there. The brush making machine 1 only has to be connected electrically and pneumatically. This allows a simple and inexpensive installation of the brush manufacturing machine 1 , Also the operator 12 Can be used to insert the brush body 3 in the brush body shots 11 on the console 28 stand.

To increase the operational safety, shut-off elements 29 provided that the working area of the operator 12 separate from the remaining machine areas. In 1 is the sake of clarity, only a shut-off 29 in the leg area of the operator 12 shown. Further shut-off elements can in particular each side next to the brush body shelves 13 be arranged.

So that the brush body feed area 14 in one for the operator 12 is arranged ergonomically favorable position, the upper run of the transport device 2 in the brush body supply area 14 over deflecting elements 30 lowered. In addition to the in 2 shown deflecting element 30 above the chain links 4 can also be a supporting deflecting element below the chain links 4 be provided.

The transition curves for lowering and lifting the chain 5 in the brush body supply area 14 as well as the deflection at the lateral ends of the transport device 2 are calculated so that in each position of the chain 5 no effective length change of the chain 5 results. The calculation can be carried out with superimposed sinusoids or with polynomial calculations, preferably with 11th or 13th order polynomials. Alternatively, balancing elements could be in the chain 5 which compensate for positional changes in the effective chain length.

To friction losses through the chain links 4 to avoid or reduce is the brush body feed area 14 with the lowered portion of the chain 5 spaced apart from the chain drive 7 arranged. The larger this distance is selected, the lower will be possible friction losses.

As in the 3 to 7 shown schematically, the individual chain links 4 the transport device 2 as a multifunction carrier for one or more brush body shots 11 educated. Depending on the type of brush to be produced, the chain links 4 in the embodiment shown with a ( 3 ) or more, up to five ( 7 ) Brush body shots 11 be fitted.

The brush body shots 11 each have only schematically illustrated clamping clips 32 on that over an actuator 33 can be brought from a clamping position into an open position. When retracting the brush body shots 11 in the brush body supply area 14 become the actuators 33 loaded and the clamping clips 32 opened to a simple insertion of a brush body 3 to enable. Once the brush body shots 11 the brush body supply area 14 leave again, eliminates the application of the actuator 33 and the tensioning clamp 32 enters its clamping position in which the brush body 3 is held clamped.

So that the brush body 3 also in the brush body feed area 14 with open clamps 32 are held securely and in particular with curved brush bodies 3 falling out of the brush body 3 from the brush body shots 11 is safely avoided is in the brush body feed area 14 a support band 31 provided for the brush body handles. The support band 31 runs synchronously with the transport device 2 around (arrow Pf2, 2 ). Because the brush body 3 so on the one hand in the brush body shots 11 and on the other hand on the support band 31 rest, these are also open clamps 32 kept safe. On the support band 31 also lateral guide elements, not shown, may be provided, whereby on the one hand a straight insertion of the brush body 3 is ensured and on the other hand, a lateral slipping of the brush body 3 during transport in the brush body feed area 14 with open clamps 32 is safely avoided.

The individual, on each one chain link 4 arranged brush body shots 11 can like in 3 to 7 represented, each formed identically. However, it is also possible that on each one chain link 4 arranged brush body shots 11 have different heights, so that the free ends of partial bristle fields that at the various stuffing devices 15a . 15b are stuffed and have different lengths, each arranged at the same height and thus very easy in the post-processing area 24 can be processed by the same post-processing facilities. For this purpose, the brush body 3 , which are equipped with shorter bristle bundles, in higher brush body shots 11 used and brush body 3 , which are equipped with longer bundles of bristles, are in lower brush body shots 11 used.
