Abstract

An apparatus for producing a multipack includes forming groups on opposite sides of a transport section. The first forming group comprises a sliding carriage that moves along and transverse to a transport direction, a format part that forms a contact surface for engaging a container, and a guiding-and-holding element that detachably secures the format part to the sliding carriage. The first and second forming groups are movable along the transport direction and transverse to the transport direction such that contact surfaces of the first and second forming groups that are opposite each other are brought into contact with containers to move the containers along the transport direction and to press the containers against each other by moving transverse to the transport direction.

First claim

The invention claimed is:

1. An apparatus for producing a multipack comprising at least two rows of containers, each of which is formed from a container group, said apparatus comprising a container inlet that receives first and second container flows, a first treatment segment that applies adhesive to containers in said first container flow, a second treatment segment that applies adhesive to containers in said second container flow, and a transport section that is arranged downstream of said first and second treatment segments and that extends along a transport direction, wherein said transport section comprises a forming device that separates container groups from said first and second container flows and compresses said container groups to form said multipack, wherein said forming device comprises first and second forming groups on opposite sides of said transport section and extending along said transport direction, wherein said first forming group comprises a sliding carriage that moves along and transverse to said transport direction, a format part that forms a contact surface for engaging a container, and a guiding-and-holding element that detachably secures said format part to said sliding carriage, wherein said first and second forming groups are movable along said transport direction and transverse to said transport direction such that contact surfaces of said first and second forming groups that are opposite each other are brought into contact with containers to move said containers along said transport direction and to press said containers against each other by moving transverse to said transport direction, and wherein said sliding carriage comprises a U-shaped support body that comprises a middle limb and side limbs that extend at right angles away from a free-face side of said central middle limb, said side limbs comprising an upper side limb, and a lower side limb.

2. The apparatus of claim 1 , wherein said guiding-and-holding element is configured as a completely exchangeable structural unit that transitions between a first state and a second state, wherein, in said first state, said guiding-and-holding is detached from said format part, wherein, in said second state, said guiding-and-holding element secures said sliding carriage and said format part to each other, and wherein said guiding-and-holding element is in said first state.

3. The apparatus of claim 1 , wherein said guiding-and-holding element comprises a strip having a U-shaped profile.

4. The apparatus of claim 1 , wherein said sliding carriage is one of several sliding carriages of said first forming group, wherein said format part is one of several format parts of said first forming group, wherein each of said format parts is detached from said sliding carriages, and wherein each of said format parts is configured to transition between a state of being detached from said sliding carriages and a state of being secured to one of said sliding carriages.

5. The apparatus of claim 1 , wherein said first forming group further comprises guide rods that mechanically couple said format part to another format part of said first forming group.

6. The apparatus of claim 1 , wherein said format part is one of a plurality of format parts in said first forming group, wherein said first forming group further comprises upper and lower guide rods that that connect said format parts to each other forming an exchangeable structural unit that comprises said guide rods and said format parts, wherein said exchangeable structural unit is detached from said first forming group, wherein said exchangeable structural unit is configured to transition between a state in which said exchangeable structural unit is detached from said first forming group to a state in which said exchangeable structural unit is attached to said first forming group.

7. The apparatus of claim 1 , wherein said guiding-and-holding element comprises a rod having a U-shaped profile.

8. An apparatus for producing a multipack comprising at least two rows of containers, each of which is formed from a container group, said apparatus comprising a container inlet that receives first and second container flows, a first treatment segment that applies adhesive to containers in said first container flow, a second treatment segment that applies adhesive to containers in said second container flow, and a transport section that is arranged downstream of said first and second treatment segments and that extends along a transport direction, wherein said transport section comprises a forming device that separates container groups from said first and second container flows and compresses said container groups to form said multipack, wherein said forming device comprises first and second forming groups on opposite sides of said transport section and extending along said transport direction, wherein said first forming group comprises a sliding carriage that moves along and transverse to said transport direction, a format part that forms a contact surface for engaging a container, and a guiding-and-holding element that detachably secures said format part to said sliding carriage, wherein said first and second forming groups are movable along said transport direction and transverse to said transport direction such that contact surfaces of said first and second forming groups that are opposite each other are brought into contact with containers to move said containers along said transport direction and to press said containers against each other by moving transverse to said transport direction, wherein said guiding-and-holding element is an upper guiding-and-holding element, wherein said first forming group further comprises a lower guiding-and-holding element, wherein said sliding carriage comprises a support body, and wherein
(1) said support body has upper and lower side limbs,
said upper guiding-and-holding element, which is in a first state in which said upper guiding-and-holding element is detached from said upper side limb, transitions into a second state, in which said upper guiding-and-holding element is secured to said upper side limb, and
said lower guiding-and-holding element, which is in a second state, in which said lower guiding-and-holding element is secured to said lower side limb, transitions between a first state, in which said lower guiding-and-holding element is detached from said lower side limb, and said second state,
or
(2) each of said upper and lower guiding-and-holding elements comprises a free-face side and
said first forming group further comprises a detachable quick-connection device that transitions between a first state, in which said quick-connection device is detached from said support body, and a second state, in which said quick-connection device mechanically attaches said support body to corresponding ones of said upper and lower guiding-and-holding elements at said free-face sides thereof.

9. The apparatus of claim 8 , wherein said first forming group further comprises a head piece and wherein said head piece comprises a strip that securely connects said upper and lower guiding-and-holding elements to each other.

10. The apparatus of claim 8 , wherein said first forming group further comprises a head piece and wherein said first forming group further comprises a container receiver on a side of said head piece that faces away from said guiding-and-holding element.

11. The apparatus of claim 8 , wherein said format part comprises upper and lower container receivers that are spaced apart from each other along a head piece and wherein said upper and lower container receivers form corresponding upper and lower contact surfaces for engaging upper and lower portions of a container.
