Brush processing device with brush body storage device capable of manual loading

The present invention relates to a brush processing apparatus having a brush body storage device that can be manually loaded, the brush body storage device having a loading portion and an output portion and an output for outputting a brush body on the output portion The device, wherein the output portion of the brush storage device is disposed in an area of the loading station of the downstream processing station.

This low-automatic brush processing equipment is used in situations where it is necessary to manufacture brushes at low cost. In the simplest case, the operator loads the brush body directly into the loading location of a processing station (e.g., a stuffer) without the presence of a brush storage device. Since the filling process for the toothbrush lasts only about 1 to 5 seconds and immediately after the other brush body has to be loaded, the operator cannot perform additional tasks, such as loading the bristle bundle into the stuffing device or carrying a brush with a finished filling. Or a new unfilled brush body container. To do this, a second operator is required, or the stuffing process must be interrupted in order to perform the corresponding work.

Because of this time-consuming and labor-intensive, a brush processing device having a stacking bin as a brush storage device is disclosed, for example, in German Patent No. DE 197 431. A plurality of brush bodies can be stacked on top of each other in the stacking bin, leaving time for other work during several filling cycles before the stacking bin needs to be refilled with the new brush body For example, filling the bristle memory.

However, this type of stacking bin is not suitable for all brush bodies. For example, a brush body profile with a undulating or protruding sheet or a brush body that has been partially bristled cannot be placed in the stacking bin.

In this case, the intermediate storage and transport of the brush body can be carried out by means of a conveyor belt and a clamp, for example, by the device described in German Patent No. DE 43 11 974 C2. However, such a device is complicated and thus expensive. In addition, such a device requires a large space.

The object of the invention is therefore to achieve a brush processing device of the type mentioned at the outset which is simple, cost-effective and capable of storing any brush body.

The object of the invention is that the brush storage device has a transport device that is rotatable about a rotational axis, the transport device having a plurality of receptacles for a brush body, the receptacle being arranged in The conveying device is circumferentially spaced apart from each other by a distance in the circumferential direction; the receiving portion is respectively matched with a holding device for fixing the brush body to the corresponding receiving portion, and the output device has at least one capable of initializing The brush ejector that moves between the position and the ejector position of the brush body to be ejected.

The operator can respectively insert a brush body into the empty receptacle of the transport device. By arranging a respective brush body separately in a housing, it is also possible to machine a brush body having a complex outer contour or partially containing bristles. The rotational movement of the transport device is carried out in the region of the output and is transferred from the respective receptacle to the respective receptacle of the downstream processing station by means of the brush ejector. Since a plurality of brush body accommodating portions are provided on the outer circumference of the conveying device, the processing station can be supplied with the brush body held in the accommodating portions, and the operator can also be at one or more working cycles of the processing station. Perform other tasks for the duration, such as refilling the stuffing material. The receptacle of the conveying device which is emptied during this time and which is returned to the loading position can then be loaded by the operator with a new brush body. Since it takes less time to load the housing with each brush body, the machining can be performed without interruption.

An advantageous embodiment provides that the delivery device has a support element on the head side and a support element on the shank side, the support element on the shank side being axially spaced apart from the support element on the head side It is provided that the support elements each have a brush body receptacle on the outer circumference. For example, the support element can have recesses which, in pairs, respectively form a receptacle for the brush body. This allows the conveying device to be manufactured simply and cost-effectively with less material, since no longitudinal side-through, solid bearings are required. With this configuration, the conveying device In addition, it has a small weight, so that the conveying device can be easily operated and rotated at a lower energy consumption.

Suitably, the support elements each have a circular or polygonal outer contour. The support element can in particular be a disk or a disk with an octagonal outer contour, for example.

Preferably, the holding device can be embodied as a clamping element and can be moved from the holding position to the release position against the restoring force. This allows the operator to simply and quickly insert the brush body into the receptacle and on the other hand allows the brush body to be ejected simply and reliably on the output point. Nevertheless, the brush body is reliably held during transport and avoids accidental detachment of the brush body from the respective receptacle.

The position of the brush body in the longitudinal direction is important, and when the brush body is ejected and the brush body is transferred to the loading portion of the downstream processing device, the brush body is located at a predetermined position and is subsequently processed, for example, the brush material is padded to the brush. The pores of the body can be accurately performed. In order to be able to transport the brush body in the desired longitudinal position, it is expedient if the brush body storage device has a longitudinal stop for the head side and/or the handle side of the brush body. In this way, the operator can insert the brush body into the receptacle in such a way that the head side and/or the handle side of the brush body rest on one of the stops and thus occupy a predetermined position in the longitudinal direction of the brush body.

Therefore, it is ensured that, according to the further operation of the downstream processing station, when a new brush body is waiting at the loading portion thereof, a brush body for transfer is provided on the output portion of the brush body storage device, and the brush body storage device is transported. The device can be associated with the drive of a downstream processing station. The delay in loading the downstream processing device may result from the fact that the conveying device of the brush storage device must first be moved into the respective transfer position, the delay being avoided by the synchronization.

Likewise, the entire brush storage device can be associated with the positioning drive of the downstream processing device. In the case of a stuffing device as a downstream processing device, the drum supporting the brush body of the stuffing device performs a positioning movement along all three spatial axes during the filling. If the brush storage device participates in the positioning movement, the positioning movement at the transfer position is not required before the brush body is transferred, thereby reducing the cycle time.

The at least one brush ejector can preferably have a pneumatic drive. It achieves simple and precise control of the brush ejector. Other types of drive can also be tested, for example by electric motor.

In order to enable the brush storage device to be quickly adapted to the other brush body type and to enable the brush body storage device to be configured in a universal manner, it is expedient if the receptacle has an adjustment element for the accommodation. The cross section of the receptacle is matched to the different brush bodies.

In order to match the brush bodies of different lengths, the support element on the head side, the support element on the shank side, the longitudinal stop on the head side, the longitudinal stop on the shank side and/or the retaining plate of the support holding device can each other Positioned in the axial direction.

Advantageously, at least one sensor for detecting the brush body in the receiving portion is provided, and preferably at least one of the following sensors is provided, the sensor detecting whether one of the sensors is located at the output portion A brush body is present in the previous housing. Although it is basically possible to provide a sensor for each of the receptacles, the sensor detects whether there is a brush body in the associated receptacle. However, in order to be able to control whether or not there is a brush body in one of the corresponding receiving portions of the output portion, it is sufficient that the output portion is provided with at least one sensor, and the sensor detects whether one of the fronts is placed A brush body is present in the housing of the output portion. If the brush body does not need to be loaded, the further rotation of the transport device can be prevented by a drive control device, so that the operator can also load a brush body before the empty accommodation portion is further rotated into the region where the output portion is inaccessible.

The brush processing apparatus, generally indicated at 1, has a brush body storage device 2 that can be manually loaded according to FIGS. 1 to 7. The brush body 3 held on the brush body storage device 2 can be transferred to the downstream processing device 4. The downstream processing device 4 is a stuffing device having a stuffing tool 5 and a drum 6 rotatably held on the drum support 7.

The brush storage device 2 has a transport device 9 rotatable about a pivot axis 8 , the transport device having a plurality of receptacles 10 for a brush body 3 , the receptacles They are arranged on the outer circumference of the conveying device and are spaced apart from each other by a certain distance in the circumferential direction. The conveying device 9 has a support element 11a on the head side and a support element 11b on the shank side, the support element on the shank side being axially spaced apart from the support element on the head side, thereby achieving A lighter weight and thus a lighter construction of the brush body storage device 2 of the quality to be moved.

A retaining plate 12 is provided between the support element 11a on the head side and the support element 11b on the shank side, said retaining plate having a plurality of retaining means 13 associated with the receptacle 10.

Correspondingly, the receptacle 10 situated in the upper region of the brush body storage device 2 forms a loading point 14. A brush body 3 can be separately loaded into the housing portion 10 in this position by the operator. By the rotation of the conveying device 9, the brush body 3 reaches the output portion 15, and the output portion 15 is located above the loading portion 16 of the downstream processing device 4. At this point, the brush body 3 can be transferred from its receptacle 10 to the drum clamping device 17 of the drum 6.

To this end, in particular as shown in Figures 5 to 7, an output device 18 having two brush ejector 19 is provided. After the brush body 3 is brought into the region of the output portion 15 by means of the transport device 9 and the empty drum clamping device 17 is located in the region of the loading portion 16 of the drum 6 (Fig. 5), through the head side and the handle The side of the body is loaded by the longitudinally displaceable actuating element 20, respectively, and the brush body 3 is ejected from the receptacle 10 of the transport device 9 by means of a brush ejector 19 (Fig. 6). At this time, the brush body 3 is pressed by its holding device 13 into the drum clamping device 17 of the drum 6. When the drum clamping device 17 fixes the brush body 3, the action member 20 can be pulled back (Fig. 7) and the drum 6 can bring the brush body 3 to the front of the stuffing tool 5 by rotating 90 degrees (Fig. 8).

The brush ejector 19 can be pneumatically driven, respectively.

The retaining plate 12 with the retaining device 13 is also clearly visible in FIG. The holding device 13 each has a stop strip 21 as a fixed stop for the brush body 3. The stop strip 21 can be adjusted in the axial direction and in its angular position by the elongated opening 22 and then fixed by means of a fixing screw 23 in order to enable the holding device 13 to Different brush bodies 3 match. The brush body 3 is clampedly held between the stop strip 21 and the clamping strip 24 rotatably supported on the pivot pin 25, wherein the clamping force passes through the stop strip 21 and the clamping strip A pressure spring 26 is provided between the 24s. If there is no brush body 3 in the respective holding device 13, the deflection of the clamping strip 24 is defined by a circular stop 27. In the case where the brush body 3 is inserted into the holding device 13, it is possible for the pair of holding devices 13 in the loading portion 14 shown in dashed lines, respectively, against the reset of the pressure spring 26 The force is deflected and the brush body 3 is clamped between the clamping strip 24 and the stop strip 21 . This allows the brush body 3 to be easily inserted into the holding device 13 and allows the brush body 3 to be easily removed.

As shown in Fig. 9, the receiving portion 10 of the supporting members 11a, 11b can be a simple groove on the outer circumference of the supporting members 11a, 11b.

In order to enable the transport device 9 of the brush storage device 2 to quickly match the shape of the different brush bodies, for example with respect to thickness and contour, as shown in FIG. 10, the support elements 11a, 11b can have on their receptacles 10 The lateral frame 28 and the support frame 29 are adjustable. The support frames can be locked in the desired position and orientation by the elongated holes 30 and the fastening bolts 31, respectively, so that the empty receiving regions of the respective receptacles 10 can be adapted to the characteristics of the type of brush body to be processed. The possibility of matching by means of the lateral frame 28 and the support frame 29 as adjustment elements is simple in construction and thus low in cost.

According to Figures 1 and 2 and Figures 5 to 7, the brush storage device 2 has a disk-shaped head-side longitudinal stop 32a and a handle-side longitudinal stop 32b, respectively. It is ensured by the longitudinal stops 32a, 32b that the brush body 3 can be inserted into the receptacle 10 in the correct axial position, which is necessary in order for the brush body 3 to be correctly transferred to the drum 6 In the barrel clamping device 17. As a result, the brush body 3 can be inserted into the corresponding receptacle 10 in a particularly simple manner. In the embodiment according to FIG. 3 , only the longitudinal side stop 32 a of the head side is provided, and in the embodiment according to FIG. 4 only the longitudinal stop 32 b of the handle side is provided. When the brush body 3 is loaded into the accommodating portion 10, it must be noted here that The brush bodies 3 bear with their respective ends against the respective longitudinal stops 32a, 32b.

The support elements 11a, 11b, the retaining plate 12 and the longitudinal stops 32a, 32b are each arranged in a rotationally fixed manner on the hollow shaft 33, which can be rotatably mounted about the rotational axis 8.

On the hollow shaft 33 there is also a driven gear 34 which is drivingly connected to the electric drive 36 via the drive gear 35 and thus achieves a rotational movement of the transport device 9. The drive unit 36 is held by the motor support 37 and the slats 38 on the drum support 7 (Fig. 2), and the entire transport unit 9 participates in the positioning movement of the drum 6 (arrows Pf1, Pf2, Pf3, Fig. 1).

In order to match the different lengths of the brush body 3, the support elements 11a, 11b, the retaining plate 12 and the longitudinal stops 32a, 32b can be positioned axially on the hollow shaft 33 and fixed in the respective positions in a manner not illustrated in detail. .

The rotary drive for the conveyor can also be coupled to the rotary drive for the drum 6 to synchronize the two rotational movements.

As an alternative to the electric drive 36, the transfer device 9 can be further connected to the brake on the hollow shaft 33 via the shifting wheel.

The brush body storage device 2 shown in the drawing has a housing portion 10 for eight brush bodies 3. It goes without saying that embodiments with more or fewer receptacles are also possible.

By means of the sensor 100 shown in FIGS. 3 to 7 , it is possible to control whether or not the brush body 3 is present in the corresponding receptacle 10 before the output point 15 . If the brush body should not be loaded, further rotation of the transport device 9 can be prevented by the drive control means, so that the operator can also insert a brush body before the empty accommodation portion is further rotated into the area where the output portion 15 is inaccessible.

It is also possible to provide a protection device which, if the operator loads the brush body 3 into the receptacle 10, monitors the loading point 14 and prevents the rotation of the transport device 9. Guarantee The guard can be realized, for example, by a light barrier or a grating.
