Glass jaw remover, especially container glass

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a jaw holder for a glass article remover, in particular a container glass, L-shaped with a vertical and a horizontal portion. The vertical portion includes means for attaching to the detachment mechanism.

BACKGROUND OF THE INVENTION Corresponding to US 1998/199621 (Nov. 25, 1998), owned by Owens-Brockway Glass Container Inc. US, a takeout mechanism for removing glass containers from molds is disclosed. The mechanism comprises pliers assemblies, each of which is intended to remove a glass container. Each clamp assembly includes a pair of opposing arms, a hinged member extending in the direction of removal of the glass containers, attached to the cylindrical housing and supporting the shaft, and coupling means carried by the hinged member and pivotally mounted on the shaft to open and grip the opposing arms of the pliers. Opposite arms of the pliers are supported by the fastener and are actuated by the fastener. Each of the collet assemblies comprises a first adjusting means comprising a bolt and nut assembly and a groove for adjustably attaching the opposing pliers arms to the coupling means to adjust the offset between the opposing pliers arms and the hinged member in the container removal direction. The second adjusting means is formed by a threaded member and a projection, after adjusting the positions of the opposing pliers arms in a plane extending transversely to the container removal direction. Each of the opposing pliers arms is formed by an L-shaped member, each L-shaped member having a groove. The first adjusting means comprises a bolt-nut assembly that extends transversely of a L-shaped groove in the member.

It is a common and industry-established solution for attaching members. The disadvantage is the laborious adjustment of the members, the jaws of the remover and the occasional dropping of the members from the remover. The adjusting means formed by the screw and the nut is currently overcome so that instead of the nut 30, a thread is formed in the holder of the L-shaped member into which the screw is screwed.

GB 2 126 211 of United Glass PLC GB (July 26, 1982) discloses a glass container remover. The remover has a thermoset composite liner with a special filler, without asbestos fiber filler, and a thermoset resin. Each of these components of the composite is stable at temperatures up to 200 ° C. The 17th claim mentions an L-shaped member of which one%

the arm is adapted to fit with the insert on the remover, and the second arm is shaped to receive the jaw member. The jaw member aligns with a depression on the second arm of the clamp member L.

In Fig. 1 of the present invention, an L-shaped jaw member is described, wherein on the vertical portion there is a gripping portion which is provided with an opening for gripping to the removal mechanism. The vertical portion of the L-shaped member is provided with a side guide on the side of the removable mechanism. The L-shaped jaw member is reinforced by side walls on both outer sides. The horizontal portion of the L-shaped jaw member has a depression flush with the insert. The recess has a shape allowing insertion of an insert having an outer semicircular circumference. On the horizontal part of the L-shaped jaw member there are on each side, one above the other, holes for receiving a pin to secure the insert against falling out. The inner circular opening of the liner is shaped according to the shape of the mouth of the removed bottle. The inserts are provided, on the outer circumference in the dividing plane, with a groove for a pin which is inserted into the holes in the jaw member to secure the insert against falling out after insertion of the insert into the L-shaped jaw member.

The disadvantage of this solution is laborious replacement of the inserts after their mechanical wear or when changing the assortment. Accurate adjustment is quite laborious. Due to the relatively compact and robust L-shaped jaw member, including its lateral reinforcement, greater weight can be expected. As regards securing the liner against falling out, there may be a certain risk of instability, the locking pins falling out during operation and long-term use at operating temperatures.

U.S. Pat. No. 4,959,896 (Aug. 31, 1989), the owner of the Union Oil Company of Caliphia US, describes the jaws of a remover. Remover jaws in bottle forming machines have an outer semicircular shape and include a spring clip for firmly holding the insert of non-metallic contact material 15 in the cavity of the remover body. The remover jaws assembly for gripping glass bottles shall consist of:

(a) an arcuate base comprising a wall member and an inwardly extending, substantially parallel, upper and lower flat member, and the flat members and the wall form a cavity; (b) a semicircular body contacting the bottle, the body positioned within the cavity and having a circularly extending surface for contacting the bottle, the body having a depression adjacent the trailing edge of the body; (c) the means for retaining the body in the cavity is formed by a flat spring mounted on an outer surface of the wall member and extending through the wall opening and having an end for engagement in the recess of the body. The arched base is made of steel. The semicircular body is made of a material containing graphite.

The disadvantage of this solution is that the body can fall out more often after the spring has been heated during operation. Another disadvantage is the higher price of the body, due to its complex shape.

Another disadvantage is the small axial play between the body and the cavity of the arched foundation.

SUMMARY OF THE INVENTION These disadvantages are eliminated or substantially reduced by the jaw holder of a glass article remover, in particular L-shaped container glass, with a vertical part and a horizontal part, the vertical part comprising means for attaching to the a takeout mechanism according to the invention. It is an object of the present invention that each bracket is provided in its vertical part with a groove at its upper end for attaching the bracket to the removal mechanism; and, on the side facing the removed glass product, stops for rapid and accurate alignment, with the upper stop surface situated below the groove level and above the locking column. Each bracket is provided with a locking post for fixation the upper surface of which is below the upper surface of the stops and the lower surface extends up to 16 Λ to the level of the lower surface of the top plate of the horizontal part. In its horizontal part, the holder is provided with a cavity adapted to receive an insert having a substantially corresponding external shape. The cavity is formed between the upper plate and the lower plate between which are the side walls. Both plates are shaped into a semicircular cut-out on the side facing the removed glass product. Each insert is provided with a locking hole for insertion 20 May of the locking pin into the locking column. The main advantage of the present invention is that it allows the use of inserts with a very simple manufacturing, construction and inexpensive design. The design allows for very simple and quick replacement of inserts and their secure securing against falling out 25 . \ 30 from the bracket. The groove is used to attach the bracket to the remover mechanism. The optimum positioning of the jaws ensures that the jaw holder is positioned precisely in the extractor. The securing post and its optimal positioning represent the most important structural element of the holder according to the invention. The locking post is located on the side facing the removed bottle. The locking post of the present invention ensures an accurate and secure positioning of the insert in the holder, while at the same time securing the insert from falling out of the holder. The cavity defined between the two plates serves as a space for insertion of the insert. The size of the cavity ensures the required axial play of the insert in the holder. Based on long-term The operating tests should have a clearance of 0.3 * 40.8 mm between the cavity and the insert for the required axial clearance. The holder of the present invention, with a locking post, is suitable for most 35 inserts manufactured and used so far, but with the requirement that the insert must additionally be provided with one locking hole.

For a smaller diameter of the mouth of the glass container, especially of glass bottles, it is preferred that the substantially vertically oriented portion of the L-shaped jaw holder has a rear side facing away from the removed glass container over the entire surface vertical and uninterrupted. In this case, it is structurally advantageous if the locking post is situated between two stops, which takes up little space and simplifies the construction and allows the insert to be locked in one place. The insert can then be of a standard size and the holder is thus usable for most existing inserts.

For a larger diameter, the glass container mouth of the bottle, in particular glass bottles for ketchup, juices, and the like. or tin jars, it is preferred that the vertically oriented portion has a rear side facing away from the removed glass container, angled in the central portion away from the removed glass container, and the adjoining base is vertical, so that the horizontal portion of the holder is extended by offset.

Preferably, the locking post is hollow, a locking pin surrounded by a spring is located therein, and a screw is located above the pin. The advantage of this design is that the locking column is located on the inside of the jaws, thus allowing the use of standard, commonly used inserts and their perfect securing against falling out during operation.

It is also advantageous if the vertical part of the holder is provided with relief holes to relieve the holder, which reduces its weight.

It is also preferred that the semicircular removable cutout is provided with a further smaller 25 'semicircular cutout situated below the locking post for easy insertion of the locking pin when changing the insert to change the container glass range, or when inserting a new insert into a new jaw, or possibly damaged inserts.

It is also preferred that a vertical recess is situated in the vertical portion of the holder, in the case of the vertical rear side of the holder 30, below the groove and above the stop on the side facing the removed glass product to facilitate manufacture of the interior space of the locking post.

It is also preferred that an aperture for pushing the liner out of the holder is located in the rear wall of the holder, at the level of the cavity.
