Glue station

The invention relates to a gluing station for gluing workpieces with a base plate on which a holder for a glue application device and a rotary table are provided, wherein the rotary table comprises a foot arranged vertically on the base plate and a table top arranged rotatably on the foot with pins adjustable in guide rails for fixing workpieces.

A gluing station of this type is known from the brochure "HESS PRESSES-Beleimarbeiten" from Reinhold Hess GmbH + Co. KG, 7460 Balingen-Weilstetten. The rotary table of the well-known gluing station consists of a square support mounted on a base plate with rollers as a base with a circular table top that can rotate on this base. On the table top there are several pins, some of which are arranged vertically in guide rails, which are infinitely adjustable and serve to hold and fix the workpieces to be glued. In addition to the rotary table, there is a space on the base plate for a gluing pressure vessel formed by a ring. Together with a glue gun connected to the vessel with the corresponding attachments, the

sets, this pressure vessel represents the glue application device of the gluing station. The table top is designed to be rotatable to make work easier for the operator. For larger workpieces, two workpiece carriers can be clamped onto the table top, on which the workpieces to be glued can then be arranged. The height of the gluing station is 92 cm according to the data in the brochure.

The object of the invention is to further improve a known gluing station from an ergonomic point of view.

To solve this problem, a gluing station of the type mentioned above is designed so that the height of the rotating table can be adjusted to suit the size of the operator. This inventive design of the gluing station allows for a more work-friendly adjustment to the respective operator, so that both male and female operators can work comfortably at the gluing station. Consequential work injuries due to poor posture, especially during intensive piecework work, are thus excluded.

An advantageous embodiment of the invention provides that the rotating table top can be adjusted in height by means of a spindle mounted in the base. By loosening a counterpart attached underneath the table top, the height can thus be continuously adjusted by simply turning it.

In another embodiment of the invention, the table top can be moved telescopically relative to the base using an attachment, whereby the attachment and the base have rows of holes that are opposite one another and the height is determined by a pin that can be pushed through the holes. In this embodiment, the height of the table top can be adjusted in steps according to the distance between individual holes. To do this, the table top is moved in height until the holes of the attachment are in the area of the desired height.

the table top should be aligned with the holes in the foot. To secure it in this position, a sturdy pin, e.g. made of steel, is inserted through the holes in the foot and the attachment.

Advantageously, the height of the table top is adjustable between approx. 850 and 1050 mm.

The invention is illustrated in the drawing using two embodiments and is explained in more detail below. Show:

Fig. 1 shows a gluing station according to the invention in a first version,

Fig. 2 shows a gluing station according to the invention in a second version, and

Fig. 3 is a section through the gluing station of Fig. 2 along the section line III-III.

Fig. 1 shows a gluing station (1) according to the invention with a mobile base plate (5) provided with rollers (6). A ring (7) is fixedly arranged on the base plate (5), e.g. by welding, which forms a holder for a pressure vessel (8) of the glue application device of the gluing station (1).

Furthermore, a rotary table (10) with a foot (11) is firmly attached to the base plate (5). The rotary table (10) comprises a table top (12) arranged at the upper end of the foot (11), on which vertical pins (13) are attached. The pins (13) are partially adjustable in guide rails (not visible in the illustration) and are used to fix the workpieces to be glued. A rotary plate (15) is arranged concentrically below the table top (12). The table top (12) and the rotary plate (15) are rotatably connected to one another.

connected. A spindle (17) is attached to the underside of the turntable (15), which extends through the head end (16) of the base (11), which is designed with a thread as a counterpart to the spindle (17), into the base. By turning the turntable (15) with the spindle (17), the height of the table top (12) can be adjusted. In the drawing, the table top (12) with the pins (13) and the turntable (15) are shown in solid lines in their lowest position and in dashed lines with the reference numerals 12', 13', 15' in their highest position.

To fix the table top (12) at a desired height, a lock nut (14) is provided on the spindle (17), which when the desired height is reached, is tightened against the head end

(16) of the foot (11). Thus, the spindle (17) is locked against the foot (11) and the height of the table top

(12)

To make it easier to adjust the height, a pin (not shown) can be provided on the table top (12) which can be pressed into a corresponding recess in the turntable (15), thereby creating a rotationally fixed connection between the table top (12) and the turntable (15). When the lock nut (14) is loosened, the height can now be adjusted by turning the table top (12). It is then no longer necessary to reach under the table top (12) to the turntable (15) if the height is to be adjusted.

A further embodiment of a gluing station according to the invention can be seen in Figure 2. The gluing station shown there is provided with the reference symbol (2). The same parts of the gluing station (2) are provided with the same reference symbols as in Figure 1.

The rotary table (20) mounted on the base plate (5) of the gluing station (2) comprises a foot (21) which at its foot end

is firmly connected to the base plate (5). The table top (22) of the rotary table (20) in turn has pins (23) for receiving and fixing the workpieces to be glued. A rotary plate (25) is arranged below the table top (22), which consists of an upper plate (25a) firmly connected to the table top (22) and a lower plate (25b) that can rotate relative to it. A downward-reaching extension (27) is attached to the lower rotary plate (25b), which extends telescopically into the interior of the foot (21) designed as a hollow body. As can be seen in particular from Fig. 3, the extension (27) adapts to the inner contour of the foot (21) with little play.

Two rows of opposite holes are provided on the extension (27) which is mounted telescopically inside the base (21), while the base (21) has at least two opposite holes. If the extension (27) with the rotary plate (25b) and the table top (22) attached to it is moved up or down, the holes in the base (21) alternately come to lie over the holes and the solid sections of the extension (shown in dashed lines inside the base (21)) in between. In order to fix the table top (22) at a desired height, a pin (24) is inserted through these holes when the holes in the base (21) and the extension (27) are aligned (see also Fig. 3).

To adjust the height of the turntable (20), the locking pin (24) is pulled out and the table top (22) is adjusted to the desired height by moving it up or down. In the area of the desired height, it must then be ensured that the nearest pair of holes in the extension (27) is aligned with the pair of holes in the foot (21). The locking pin (24) is then pushed through these holes again, and the table top (22) is set at the desired height.

•&Oacgr;—

In Fig. 2, the table top (22) with the pins (23) and the turntable (25) are shown in solid lines in their lowest position and in dashed lines with the reference numerals 22', 23', 25' in their highest position.

With a gluing station according to the invention, the height of the turntable can be easily and quickly adjusted to the size of the operator working with the gluing station. This height adjustment option contributes significantly to an ergonomic design of the workplace.
