The invention relates to a method and to a device for producing a butt-welded joint between two pipe segments (38, 39) of a pipe (27, 28) made of a weldable plastic material, each pipe segment being held by a gripping means (14, 15), pipe end cross-sections of the pipe segments (38, 39) being machined with the aid of a tool means (11) for forming welding contact surfaces (40, 41), said tool means (11) being disposed in a stationary manner in a separating plane (37) for machining the welding contact surfaces (40, 41) and a separating cut for forming the pipe segments (38, 39) being realised by the gripping means (14, 15) moving the pipe (27, 28) relative to the tool means (11) in the separating plane (37), said separating cut simultaneously serving to form the welding contact surfaces (40, 41).

A tube joining device which is capable of preventing occurrence of a joining failure. The tube joining device includes: a first tube holding portion for holding a first tube; a second tube holding portion for holding a second tube; a tube superimposing portion that aligns the first tube and the second tube; and a switching mechanism switching from a state of holding the second tube to a state of releasing the second tube.

Provided is a tube joining device that allows a user to easily and appropriately perform setting of tubes which become a joining target, and is capable of preventing occurrence of a joining failure caused by a setting error of the tubes in advance. A tube joining device 1 includes: a first tube holding portion 41 that is capable of holding a first tube T1; a second tube holding portion 42 that is disposed in adjacent to the first tube holding portion, and is capable of holding a second tube T2 at a position that is parallel to the first tube; and a housing 2 that is provided with a cover member 20 that is closed to cover fusion-joining sites C of the first tube and the second tube. The cover member is slidable along a direction in which the first tube and the second tube are disposed in parallel.

[Object] Provided is a tube joining device that allows a user to easily and appropriately perform setting of tubes which become a joining target, and is capable of preventing occurrence of a joining failure caused by a setting error of the tubes in advance.

[Solving Means] A tube joining device 1 includes: a first tube holding portion 41 that is capable of holding a first tube T1; a second tube holding portion 42 that is disposed in adjacent to the first tube holding portion, and is capable of holding a second tube T2 at a position that is parallel to the first tube; and a housing 2 that is provided with a cover member 20 that is closed to cover fusing-joining sites C of the first tube and the second tube. The cover member is slidable along a direction in which the first tube and the second tube are disposed in parallel.

Provided is a tube joining apparatus that allows a user to easily and properly set tubes to be joined, and can prevent occurrence of joining failures due to tube setting errors.

A tube joining apparatus 1 includes a housing, a lid relatively movable toward and away from the housing, a tube holding part that holds a first tube and a second tube individually in a state of being placed side by side in an oblique direction with respect to a height direction of the housing, and a tube pressing part that presses the first tube and the second tube against each other as the lid relatively moves toward the housing.

[Object] To provide a tube joining device in which the degree of freedom of device design is improved.

[Solving Means] A tube joining device 1 includes a delivery mechanism 500. The delivery mechanism includes a first pusher member 542 that is provided to perform forward movement and backward movement along a delivery direction and delivers a wafer WF to a first position PS2 that is set between a take-out position PS1 at which the wafer WF is taken out from a cassette WC and a stand-by position PS3, and a second pusher member 543 that is provided to perform forward movement and backward movement along the delivery direction in combination with the first pusher member, and delivers the wafer from the first position to the stand-by position. An operation of delivering the wafer by the first pusher member is capable of being switched to an operation of delivering the wafer by the second pusher member in synchronization with forward movement and backward movement of the first pusher member and the second pusher member.

[Object] Provided is a tube joining device which is capable of preventing occurrence of a joining failure caused by a setting error of tubes in advance, and in which tube holding and release of the holding are realized by a simple device configuration.

[Solving Means] A tube joining device 1 includes: a first tube holding portion 160 that is capable of holding a first tube T1; a second tube holding portion 230 that is capable of holding a second tube T2; a tube superimposing portion 30 that disposes the first tube and the second tube in a superimposed manner; and a switching mechanism 240 that is capable of switching holding of the second tube by the second tube holding portion and release of the holding. The switching mechanism applies a biasing force for maintaining a state in which the second tube is held to the second tube holding portion, and applies a biasing force for maintaining a state in which the holding of the second tube is released to the second tube holding portion in accordance with relative approaching of the tube holding portions.

The invention discloses an apparatus for aligning and supporting a first and a second length of thermoplastic tubing, preparatory to and during cutting and welding of said lengths of tubing, that includes a first holder arranged to accommodate portions of the first and second lengths of tubing in a first and a second elongated holding space respectively, a second holder arranged to accommodate portions of the first and second lengths of tubing in a third and a fourth elongated holding space respectively, and movable in a direction essentially perpendicular to the holding spaces of the first and second holders from a cutting position, a cutting means arranged between said first and second holders for cutting said lengths of tubing when the second holder is in the cutting position and an aligning means to align these lengths of tubing with each other.

A device for welding thermoplastic tubes to a welding method, and to a welding knife. The device is provided for welding thermoplastic tubes, wherein the tubes are placed into tube holders and squeezed with the aid of tube clamps. A welding knife is moved between the first and the second tube holder and severs the tubes in the process. Cut ends and residual ends are thereby produced. The cut ends are aligned with one another by a relative movement of one tube holder with respect to the other tube holder and, by a horizontal movement of the two tube holders, are welded simultaneously to form continuous tubes.
