CONSTITUTION: The disengageable ratchet mechanism 30 to receive and take out a container 1 from a holder 13 is mounted on a holder 12 in order to hold jaws 13, 14 of the holder 12 together in transportation and cleaning process of the container 1.

Description

[Detailed description of the invention]

0001

FIELD OF INDUSTRIAL APPLICATION The present invention relates to a washing machine for bottle-shaped containers such as bottles, ampoules or flasks, which is equipped with a conveying device for feeding the containers to various processing stations. The device has a holder equidistantly spaced on an endless pair of conveyor chains and having relatively pivotable jaws for holding the container at its neck, and further includes a lever coupled to the jaws for holding the container at its neck. for the pivoting of the jaws for the purpose of receiving and removing them from the holder, each pair of levers having a device for keeping the jaws of the holder together.

0002

BACKGROUND OF THE INVENTION In known washing machines of the above-mentioned type, the jaws of a holder, each containing a plurality of containers, are pulled towards each other by a spring acting on a lever. The spring must have a sufficient tensile force to ensure that the container does not fall out of the jaw recess during transport and during the washing process in the washing machine. Even if the deviation of the diameter of the container neck is within the permissible range, thin-walled containers often break due to strong spring forces if only one or two containers are clamped by the jaws. be.

0003

OBJECTS OF THE INVENTION Therefore, an object of the present invention is to improve the washer of the type mentioned at the beginning to provide a washer that can reliably hold containers and reliably prevent container breakage. The challenge is to provide.

0004

[Means for Solving the Problems] In order to solve the above problems, in the structure of the present invention, the device for holding both levers of the holder together is formed by a ratchet mechanism.

[0005]

The washing machine constructed as described above has the following advantages over known washing machines. That is, in the washer according to the present invention, the jaws of the holder can be held together without applying pressure to a container loosely held in the notch of the jaw, and in this case, the ratchet mechanism allows the ratchet mechanism to move the jaws of the holder to the diameter of the container. can be maintained at a predetermined interval corresponding to

Further advantageous embodiments of the washing machine according to the invention result from the features of the subclaims. With the structure according to claim 2, the structure of the ratchet mechanism can be particularly simplified. Further, with the structure as described in claim 3, handling of the ratchet mechanism becomes particularly easy.

[0007]

[Embodiment] A conveying device for a washing machine for a bottle-shaped container 1 has two endless conveyor chains 10 and 11 extending parallel to each other.
0,11 comprises a plurality of holders 12, arranged at equal distances from each other, for containers 1 to be cleaned, which have a body 2, a neck 3 and a head 4. The holder 12 has two elongated jaws 13 and 14 that are rotatable relative to each other in order to grip and hold a plurality of containers 1, respectively. The jaws 13, 14 are provided with triangular notches 15, 16 facing each other, which in pairs grip around the neck 3 of the individual container 1. Jaws 13, 14 with recesses 15, 16 adapted to the shape of the container 1 are exchangeably fastened to strips 17, 18, which are connected via arms 19 to rods 21, 18. It is tightly connected to 22. Both rods 21, 22 of each holder 12 extend between the two conveyor chains 10, 11 and are rotatably supported by journals 23 on the hinges of the links 24, 25 of the conveyor chains 10, 11.

Levers 26 and 27 are fixed to rods 21 and 22 near both conveyor chains 10 and 11,
In the closed position of the jaws 13, 14 of the holder 12, the levers 26, 27 extend approximately parallel to the arm 19 holding the jaws 13, 14.

In order to maintain the closed position of both jaws 13, 14 of each holder 12 and to pivot them apart, the levers 26, 27 of each holder 12 are connected to each other by a ratchet mechanism 30. Ratchet mechanism 30
has a rack 31 with serrated teeth 32 on the first lever 27 and a locking member in the form of a ratchet 33 on the second lever 26. Pin 35 of lever 27
A rack 31, which is pivotably mounted on the lever 26, passes through a through hole 36 in the lever 26 and is pressed there against a ratchet 33 by a ball 38 loaded with a compression spring 37. This causes the ratchet 33 to engage in the gap of the serrated teeth 32 of the rack 31, so that the jaws 13, 14 of the holder 12 are kept in the closed position. Both levers 26, 27 of each holder 12 furthermore have one tooth segment 40, 41 in each case close to the pivot axis of the levers 26, 27. The tooth segments 40, 41 engage one another in pairs, so that after disengagement of the ratchet mechanism 30 both jaws 13, 14 of each holder 12 can be pivoted in the same manner.

For loading and unloading containers 1 into the holders 12 of the transport device, the rack 31 is pressed against the spring force of the compression spring 37 towards the pivot axis of the lever 26, so that the rack 31 serrated teeth 32 are disengaged from ratchet 33 . After the ratchet mechanism 30 is disengaged, both jaws 13 of the holder 12,
14 can be pivoted away from each other, so that the container 1 can be inserted into and removed from the notches 15, 16 of both jaws 13, 14. During a new loading of the holder 12, the two jaws 13, 14 of the holder 12 are moved towards each other again;
This causes the ratchet 33 to once again engage the serrated teeth 32 of the rack 31, possibly jumping over one or more teeth, and reaching the closed position in which the ratchet mechanism 30 becomes active.

In the embodiment described above, the holder 12 has two hard jaws 13, 14 each. If it is desired to hold each container 1 flexibly, alternatively a plurality of spring arms 4 are provided in the region of the recess 15 instead of the two jaws 13 or 14.
4 is arranged on the rod 21 (FIG. 3). The spring arm 44 has at its free end a finger 45 which grips the neck 3 of the container 1 in a partially surrounding manner, which together with the recess 15 of the associated jaw 13 forms a holding mechanism. There is. Spring arm 44 has bent back end 46
The end 46 is located in the hole 47 of the rod 21 and is fixed by a screw 48 (FIG. 3).
